Abstract: A solenoid valve includes a valve body having a valve cavity, a first delivery tube having a first tube cavity, a second delivery tube having a second tube cavity, and an electromagnetic member connected to the valve body. The first delivery tube is connected to the valve body at one end and the first tube cavity is in communication with the valve cavity. The second delivery tube is connected to the valve body at one end and the second tube cavity is in communication with the valve cavity. At least one of the first delivery tube and the second delivery tube is a bent tube. The electromagnetic member is configured to control communication and disconnection of the first delivery tube and/or the second delivery tube with the valve cavity.

Abstract: A fixation apparatus includes a base, a wire fixing device mounted on the base, and a pressing device mounted on the base. The wire fixing device positions and fixes a wire on a circuit board and includes a fixing frame mounted on the base and a moving unit received in a receiving chamber of the fixing frame. The fixing frame has a first positioning groove. The moving unit is movable between a clamping position and a release position and has a second positioning groove coupled with the first positioning groove. The wire is inserted into a wire insertion hole in the circuit board between the first positioning groove and the second positioning groove when the mobile unit is moved to the release position. The wire is clamped and fixed between the first positioning groove and the second positioning groove when the moving unit is moved to the clamping position.

Abstract: A system for feeding a diaphragm includes a diaphragm separating device adapted to separate a diaphragm from a stack of diaphragms, a first visual device adapted to identify the diaphragm separated from the stack of diaphragms and a position of the diaphragm, a robot adapted to pick up the diaphragm separated from the stack of diaphragms under guidance of the first visual device, and a second visual device adapted to check whether the diaphragm picked up by the robot is a single diaphragm.

Abstract: A system for feeding a diaphragm comprises a diaphragm separating device adapted to separate a single diaphragm from a stack of diaphragms and a visual device adapted to identify the single diaphragm and a position of the single diaphragm separated from the stack.

Abstract: A positioning device that has a support table, two pairs of sliding blocks slidably mounted in the support table, a positioning plate extending vertically at the top of each sliding block, a base on which the support table is supported, a cylinder in the base, a ball in the cylinder, a piston rod slidably mounted in the cylinder and pushing the ball to move upward in a vertical direction, so that the ball drives the two pairs of sliding blocks to move away from each other in the first horizontal direction and the second horizontal direction, respectively, until the positioning plates of the two pairs of sliding blocks abut against four inner walls of the opening of the circuit board, respectively, to allow the electronic device to be received in a positioning slot defined by the positioning plates, and a release mechanism that drives the piston rod to move downward in the vertical direction to allow the two pairs of sliding blocks to be moved toward each other in the first horizontal direction and the second
