Abstract: The invention provides an electronic component mounting apparatus which can obtain a relative vertically moving stroke of a suction nozzle and is applicable to electronic components ranging from thin to thick ones. The electronic component mounting apparatus of the invention has a suction nozzle for picking an electronic component up from a plurality of component feeding units supplying the electronic component to a component pickup position and mounting the electronic component on a printed board, where a mounting head movable along a beam can move vertically by a head vertical movement device and the suction nozzle provided on the mounting head can move vertically by a nozzle vertical movement device 50.

Abstract: The invention is directed to correcting of a lower end level of a suction nozzle during manufacturing running based on the lower end level of the suction nozzle measured after a mounting operation. An electronic component mounting apparatus for picking electronic components up from component feeding units by suction nozzles and mounting the electronic component on a printed board is provided with a line sensor unit for measuring a lower end level of the suction nozzle after a component mounting operation on a printed board. A CPU calculates a descending amount of the suction nozzle at a pickup station and a mounting station based on a value measured by the line sensor unit, and rotates a stroke motor to move a moving body to a position where the suction nozzle can descend by the amount. Therefore, the electronic component can be picked up and mounted on the printed board properly even if the suction nozzle is worn with time.

Abstract: This invention is directed to prevention of setting a component feeding unit set with other storage member than a storage member storing same type of components as components in shortage in an electronic component mounting apparatus. A component mounting apparatus sends notice information about component shortage to a control computer when a number of electronic components in a storage member reduces and reaches a level for sending the notice information of component shortage during mounting operations. The control computer stores the notice information, and sends the notice information to a monitor computer to display this information on a monitor. A new storage member having the corresponding components is set in the component feeding unit based on the displayed notice information, and an operator inputs information A about which component feeding unit is set with the storage member and which components are stored in the storage member set in the component feeding unit.

Abstract: The invention is directed to quick adjustment of a positional relationship between two axes when an error occurs in the positional relationship between the axes when a beam is moved by two drive sources. According to movement of the beam for component picking and mounting operations, linear scale signals (outputs relating to positions of one drive axis and another drive axes) from linear scale reading heads are inputted to a Y2 driver and a Y1 driver respectively.

Abstract: This invention provides an electronic component mounting apparatus which can detects an electronic component held by a suction nozzle without fail after a mounting operation of electronic components on a printed board and perform various processes in a case where the electronic component is held by the suction nozzle.

Abstract: This invention provides a board positioning method where a stopper and so on are not required when positioning a printed board in an X direction. Servo motors of a board supplying conveyer portion and a board positioning portion are driven to start carrying of a board. When a first board detection sensor detects the board before timeout of a first timer which starts timekeeping together with the carrying of the board, second and third timers start timekeeping. The servo motor starts decelerating, decelerates to an arbitrary speed, and keeps a constant speed after timeout of the second timer. When a second board detection sensor detects the board before timeout of the third timer, the servo motor is controlled to decelerate and stop the board at an arbitrary position, and a board recognition camera takes an image of a positioning mark of the board stopping at the board positioning portion to recognize a position of the printed board.

Abstract: When an electronic component is recognized to be improper and the CPU detects that a “component recognition monitoring navigation mode” is set for a component feeding unit feeding the component, the “component recognition monitoring navigation mode” is activated to shift to an adjustment mode and an operator decides whether or not the picked-up component is to be discharged by visually examining a component recognition image displayed on a CRT. When the judgment of the component as improper is correct upon the visual examination of the operator, the picked-up component is discarded and a picking-up operation is repeated. When the judgment is not correct, the component is not discarded, the illuminating condition is adjusted for the component and the component library data is corrected. After this correction, if linked, a component recognition test is executed and the library informing is performed.

Abstract: This invention provides a low-cost electronic component feeding device which stabilizes a pickup position of an electronic component and does not require a highly accurate sprocket. A component feeding unit is fixed to an adjusting jig, a recognition camera moves to a component pickup position and takes an image of each of feeding teeth formed around a sprocket, and a recognition processing portion performs recognition processing and calculates a position of each of the feeding teeth. In this case, for each of the numbers corresponding to the feeding teeth checked through a checking window, positional data of each of the feeding teeth which are a recognition processing result of the recognition processing portion are stored in a memory by using an input device. After such an adjusting operation of the component feeding units is completed, the component feeding units each mounted with a storage tape are fixed to the electronic component mounting apparatus.

Abstract: The invention provides an electronic component mounting method which improves a work efficiency and enables pickup of electronic components without fail. A component feeding unit mounted with a master tape formed with pickup position indication holes is fixed to an adjusting jig. A recognition camera takes an image of a recognition mark to calculate a center position thereof, moves to a position corresponding to a component pickup position previously stored in a memory portion, and takes an image of the pickup position indication hole provided in the master tape to calculate a component pickup position. Data on a positional relationship between the recognition mark and the pickup position based on a result of this recognition processing are stored in a memory in the component feeding unit. The component feeding units each mounted with a storage tape are fixed to a base of an electronic component mounting apparatus.

Abstract: There is provided an electronic component-recognizing device for taking an image of an electronic component brought to a component-sensing station, for recognition thereof. The component-sensing camera takes the image of the electronic component by utilizing reflected light from the electronic component. A lighting mechanism lights the electronic component. The lighting mechanism comprises a light-guiding element, a ring light guide, and a light source. The light-guiding element is arranged annularly such that the light-guiding element can diffuse illumination light and emit the diffused illumination light toward the electronic component obliquely from below. The ring light guide holds the light-guiding element. A light source supplies the illumination light to the light-guiding element.

Abstract: The invention is directed to performing of an effective checking and aligning operation of component pick-up positions at component feeding units used for manufacturing by performing the operation sequentially at a time. A board recognition camera takes an image of a feeding position of a component feeding unit and the image is displayed being superimposed over a graphic image of a suction nozzle on a CRT. When an operator operates a trackball to move a cursor to an “execute visual alignment” menu and clicks a left button there, the stored image (memory image) becomes movable freely in any direction according to a trackball operation. The stored image (memory image) is moved to match a cross line and an outline of a graphic suction nozzle (component pick-up position) for visual alignment with a component feeding position. Then, the operator clicks both right and left buttons of the trackball to store an alignment value of the position in a RAM.
