[0002] In the field of automation within the photovoltaic industry, the length of the crystal rods emerging from the crystal pulling furnace in automated crystal picking equipment is variable. During the picking process, the bottom of the crystal rod must first be supported by a crystal rod support. Because the length of the crystal rod is uncertain, a contact signal needs to be transmitted immediately after the crystal rod support contacts the rod, and the lifting process needs to stop. However, the crystal rods are very long, and the picking equipment is also very long. Existing methods that install sensors on the crystal rod support suffer from difficulties in connecting and bundling the signal transmission lines, frequently leading to malfunctions and inability to continue operation. Furthermore, the transmission lines often become tangled, making the overall operation more cumbersome and increasing the maintenance frequency. Therefore, a device needs to be developed to solve this technical problem. Utility Model Content

[0038] The positioning and triggering device for the crystal-retrieving cart's base is installed on the crystal-retrieving cart. The base 3 is connected to a transmission mechanism on the crystal-retrieving cart via a chain 311. The base 3 is guided by a guide wheel 318 that is movably connected to a U-shaped groove (guide groove) on the column 2 of the crystal-retrieving cart. This structural design is intended to connect the positioning and triggering device of the crystal-retrieving cart of this invention with existing crystal-retrieving carts to achieve transmission.
[0039] The preferred photoelectric sensor model is Omron E3JK-RR11-2M-R (free power supply type, retroreflective type).
[0040] The device is also equipped with a PLC control system, and the photoelectric sensor 1 is connected to the PLC control system to realize signal feedback, informing the existing crystal-picking cart whether the crystal rod has arrived.
[0041] In actual operation, the base 3 is installed on the existing column 2 of the crystal picking vehicle and connected by a chain 311 and a connecting seat 310. The photoelectric sensor 1 is installed on the side wall of the column 2. When operation is required, the movable pressure plate 302 of the base moves upward with the chain 311. The guide wheel 318 guides the downward movement on the column 2, causing the base to rise. When it rises and contacts the crystal rod, the movable pressure plate 302 moves downward due to the weight of the crystal rod. At the same time, the pressure plate adjusting seat 303 moves downward, causing the limiting groove 308 to move downward, which in turn causes the shift fork 307 to swing the light shield 305, making the light shield 305 swing. When flipped up, the optical path between photoelectric sensor 1 and reflector 306 is connected, and photoelectric sensor 1 outputs a signal that the crystal rod contacts the base 3. The PLC control system can send a signal to the existing robot or other equipment to remove the crystal rod. When the crystal rod is removed, the reset spring 301 resets and pushes the base movable pressure plate 302 and pressure plate adjusting seat 303 to reset. Then, the pressure plate adjusting seat 303 drives the limiting groove 308 to move upward, which in turn drives the fork 307 to swing the light shield 305, so that the light shield 305 resets. At this time, the optical path between photoelectric sensor 1 and reflector 306 is blocked; photoelectric sensor 1 outputs a signal that the crystal rod is removed.
[0042] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
