[0029] The marking mechanism 7 includes a slide bar 71, a roller 72, a chuck 73, an elastic telescopic strip 74, a transmission bar 75 and a seal 76. The slide bar 71 is slidably connected to the inner wall of the side guide plate 28, the roller 72 is rotatably connected to the inner wall of one end of the slide bar 71, the elastic telescopic strip 74 is fixedly connected to the other end of the slide bar 71, the chuck 73 is fixedly connected to the front and rear sides of the slide bar 71, the transmission bar 75 is fixedly connected to the bottom end of the elastic telescopic strip 74, and the seal 76 is fixedly connected to the surface of the transmission bar 75. When the limit plate 63 rotates, the spring will drive the chuck 73 to move in the direction of the limit plate 63, the chuck 73 drives the slide bar 71 to move, and the slide bar 71 is tightly attached to the surface of the limit plate 63 through the roller 72. When the limit plate 63 rotates and When code 27 is limited, roller 72 will move according to the surface trajectory of limit plate 63, so that roller 72 and slide bar 71 move toward the direction close to limit plate 63, slide bar 71 drives elastic telescopic strip 74 to move, elastic telescopic strip 74 drives transmission bar 75 to move, transmission bar 75 drives seal 76 to move, and after seal 76 moves, it contacts with both sides of silicon rod body 5 and stamps both sides of silicon rod body 5, so that subsequent workers can remove smaller silicon rod body 5 for separate inspection to see whether it meets the use requirements; the surface of elastic telescopic strip 74 contacts with the inner wall of counterweight positioning tooling 21, a spring is arranged between chuck 73 and side guide plate 28, and the circumferential surface of roller 72 contacts with the surface of limit plate 63.

[0030] Working principle: When the counterweight 27 is placed on the counterweight plate 26, the counterweight plate 26 drives the sleeve 62 to move downward, and the sleeve 62 will slide down on the circumferential surface of the spiral rod 61, and the block on the inner wall of the sleeve 62 will move in the non-self-locking spiral groove on the surface of the spiral rod 61, so that the block rotates along the spiral groove, and the block drives the sleeve 62 to rotate, and the sleeve 62 drives the limit plate 63 to rotate, and the limit plate 63 will rotate to the top of the counterweight 27 and limit it to prevent the counterweight 27 from falling off the counterweight plate 26 when the device is transmitted on the conveyor table, thereby affecting the subsequent pressing and bonding effect between the silicon rod body 5, the plastic plate 4 and the crystal support 3.

[0031] When the size of the silicon rod body 5 is relatively small, the distance that the counterweight plate 26 is pressed downward by the counterweight 27 will be greater, and the counterweight plate 26 will simultaneously drive the side guide plate 28 to move downward. After moving downward for a certain distance, it will contact the top of the pressure rod 81 and push the pressure rod 81 to move downward. The pressure rod 81 drives the transmission rod 82 to move downward, and the transmission rod 82 drives the push plate 83 to move through the guidance of the inclined groove on the inner wall of the push plate 83. The push plate 83 drives the two positioning rubber strips 214 to further gather together through the elastic telescopic rod 84, so that the small-sized silicon rod body 5 can be positioned and clamped.

[0032] When the limit plate 63 rotates, the spring will drive the chuck 73 to move in the direction of the limit plate 63, and the chuck 73 will drive the slide bar 71 to move. The slide bar 71 is tightly attached to the surface of the limit plate 63 through the roller 72. When the limit plate 63 rotates and limits the counterweight 27, the roller 72 will move according to the trajectory of the surface of the limit plate 63, so that the roller 72 and the slide bar 71 move in the direction close to the limit plate 63, and the slide bar 71 drives the elastic expansion bar 74 to move, and the elastic expansion bar 74 drives the transmission bar 75 to move, and the transmission bar 75 drives the seal 76 to move. After the seal 76 moves, it contacts the two sides of the silicon rod body 5 and stamps the two sides of the silicon rod body 5, so that subsequent workers can remove the smaller silicon rod body 5 for separate inspection to see whether it meets the use requirements;

[0033] When the silicon rod is bonded and positioned, the counterweight plate 26 is clamped by the manipulator, so that the manipulator lifts the counterweight positioning fixture 21 through the counterweight plate 26. When the manipulator moves the counterweight plate 26 upward, the counterweight plate 26 will still be pressed on the top of the silicon rod body 5 by its own weight. At this time, when the manipulator lifts the counterweight plate 26, the counterweight plate 26 will move up and generate relative displacement with the stationary counterweight positioning fixture 21. Therefore, the upward reset of the counterweight plate 26 will drive the side guide plate 28 to reset, and the side guide plate 28 will drive the two positioning silicon rod bodies 5 to reset. The positioning strips 214 move away from each other and reset, so that the positioning strips 214 no longer clamp the silicon rod body 5 for positioning, so that when the manipulator continues to move up, the two positioning strips 214 have moved away from each other to the maximum distance, so the side guide plate 28 will not be able to continue to move up in the counterweight positioning tooling 21. Therefore, the manipulator can lift the entire counterweight positioning tooling 21 through the counterweight plate 26 and the side guide plate 28, and automatically reset it during the lifting process, which is convenient for subsequent reuse, and the counterweight weight 27 will always be placed on the top of the counterweight plate 26 without being removed.
