  • Patent number: 10286487
    Abstract: Laser processing of sapphire is performed using a continuous wave laser operating in a quasi-continuous wave (QCW) mode to emit consecutive laser light pulses in a wavelength range of about 1060 nm to 1070 nm (hereinafter “QCW laser”). Laser processing of sapphire using a QCW laser may be performed with a lower duty cycle (e.g., between about 1% and 10%) and in an inert gas atmosphere such as argon or helium. Laser processing of sapphire using a QCW laser may further include the use of an assist laser having a shorter wavelength and/or pulse duration to modify a property of the sapphire substrate to form absorption centers, which facilitate coupling of the laser light pulses of the QCW laser into the sapphire.

  • Patent number: 8899459
    Abstract: In a breaking operation, a substrate is moved so that a blade can be situated in line with a scribe line, and the blade is lowered to break the substrate. After the breaking, the blade is raised. Then, the substrate is moved along its surface while taking an image of the substrate by using a camera after the breaking. Moreover, the blade is lowered to break the substrate. After the breaking, the blade is raised. Then, the substrate is moved along its surface while performing image processing concurrently. After the movement of the substrate, the position of the substrate is corrected so that the following scribe line to be cut for breaking can be situated immediately below the blade. In this way, the time required for breaking the substrate formed with a multiplicity of scribe lines into pieces can be shortened.

Furthermore, the anvil is coupled to the second member, such that the anvil could move from a crushing position to a non-crushing position, which allows for crushing and splitting of the pill, respectively.

    Abstract: A tearing method for tearing a polarizing plate, including: after a tear-initiation edge of a polarizing plate defectively attached on a liquid crystal panel is torn away from the panel, turning on a pneumatic maintaining device to keep the tear-initiation edge at a torn-away state; moving the pneumatic maintaining device and a tearing platform such that the tear-initiation edge can be located in a tearing assembly; and clamping the tear-initiation edge in the tearing assembly and further tearing the polarizing plate by the relative movement between the tearing platform and the tearing assembly. The present disclosure further provides a tearing apparatus for tearing the polarizing plate. The tearing method and device allows the polarizing plate to be torn semi-automatically, improves the controllability of the tearing process of the polarizing plate, and further improves the yield rate of the panel as well as reduces the industry safety risks.

    Abstract: A wrapping film dispenser has a generally cylindrical container that defines a cavity for accommodating a wrapping film roll, and further defines a slot extending along its length for extracting a sheet of wrapping film through the slot. A gripping pad member is rigidly attached at a first lengthwise edge of the slot. A locking element is rigidly attached proximal to a second lengthwise edge of the slot. The locking element extends towards the gripping pad member, presses the extracted wrapping film sheet against the gripping pad member, and restricts movement and prevents roll back of the extracted wrapping film sheet. A cutting frame is rigidly attached proximal to the first lengthwise edge of the slot above the gripping pad member, and has a protruding element located at a predetermined location on the cutting frame for cutting the wrapping film sheet extracted out through the slot.

    Abstract: A chisel bit of a percussion tool for penetrating hard surfaces includes a shaft having a mounting end, a working end and upper and lower protuberances formed along its length. The upper protuberance provides for retaining the mounting end of the shaft within a body of the percussion tool. The lower protuberance forms a retaining collar beyond the body of the percussion tool against which a resilient extractor is mounted along the shaft. The resilient extractor includes an elastomeric member that is positioned by the retainer collar along the shaft to contact the hard surfaces penetrated by the chisel bit and exert a resilient bounce back force against the hard surfaces when the chisel bit has penetrated to a given depth to prevent the chisel bit from becoming stuck in place.

    Abstract: A split bearing ring according to the invention includes two or more split portions into which the split bearing ring is divided with respect to a circumferential direction. Surfaces of the split portions other than circumferential end faces of the spit portions have hardness of HRC 59 or higher, the surfaces of the split portions other than the circumferential end faces are quenched and tempered, and the surfaces of the split portions other than the circumferential end faces have a prior austenite grain size of No. 6 or above. The split portions are formed by applying a load to a bearing ring such that stress generated on one end side of the bearing ring with respect to an axial direction is larger than stress generated on the other end side of the bearing ring with respect to the axial direction.

    Abstract: A method and system for preparing polysilicon slim rods, the method and system including: placing a piece of polysilicon on a fixture; applying a predetermined laser beam or abrasive jet to the piece of polysilicon; and separating a polysilicon slim rod from the piece of polysilicon. The laser beam may be used for either cutting or for cracking depending on the operating parameters chosen. There may also be various combinations of cutting and cracking used in order to separate the slim rod from the piece of polysilicon. For example, the laser cut may be a scribing and/or partial cut and the separation may be completed by cracking the remaining silicon. In this case, the cracking may be accomplished by, for example, mechanical bending or laser cracking. Generally speaking, a laser beam used for cracking may be different from and have differing operating parameters from a laser beam used for cutting.
