The principle of the design is as follows: as shown, the material is firstly penetrated: the terminal material belt is discharged from the material disc, the material supporting metal plate at the feeding end assists in smoothly transferring the terminal material belt to the feeding runner, the terminal material belt is always penetrated to the position of a feeding positioning PIN at the discharging end through the runner, the positioning PIN can penetrate a PIN hole of the terminal material belt, and meanwhile, an optical fiber signal is aligned to the PIN hole position, so that the initial position is correct; and then the clamping cylinder acts to drive the upper clamping block to move and act together with the lower clamping block to clamp the terminal material strip, the servo motor is started at the moment, the terminal material strip is pulled to a specified position (a correct position where the die can be closed) through the transmission of the screw rod assembly, then the clamping cylinder is released (returned), and the servo system returns to complete one cycle.
The key problem that above-mentioned mechanism need solve is that the position of terminal is correct when guaranteeing the mould compound die, otherwise probably causes the defective products of moulding plastics, probably damages the mould when serious. Therefore, the mechanism needs to ensure that the clamping materials must be clamped and do not slip; the second is to confirm the correct position again by using the optical fiber signal. Strive for all the things.
the mode that the servo motor drives the screw rod to move is smooth and stable, but the moving part needing to be driven cannot be too heavy and has too high sound velocity.

The structure of the screw part is then outlined as shown in the figure: after the electric work is normal, the clamping cylinder is at the initial position (the upper position in the figure), the servo motor finds the initial position of the servo motor (when the induction sheet in the figure moves to the rightmost end, the right induction switch gives a signal, which is a right limit position; similarly, when the induction sheet moves to the leftmost end, the left limit position is provided; when the induction sheet moves to the middle induction switch, the induction switch is the original position, and the position which is deviated according to the requirement is the initial position of the structure), the initial positions of the two power parts are determined and then the servo motor starts to work, the action sequence is a clamp cylinder clamp terminal-injection mold open (action of mold, not shown here) -servo start shift to designated position-injection mold close (action of mold, not shown here) -clamp cylinder release-servo motor return-clamp cylinder clamp terminal-and then cycle the above actions.
In order to quickly find the initial position, two auxiliary devices are added:
one is that three groups of optical fibers (the number of the optical fibers can be set according to specific product characteristics) are added at a feeding end; one of the three groups of optical fibers is aligned with the PIN holes of the terminal material belt to ensure that the material pulling position or the initial position is correct, and the other two groups of optical fibers are used for detecting the product characteristics, such as the absence of corner defect fragments, the need of detecting an important characteristic, or the presence of the terminal material belt.
