[0020] Example 1

[0021] A pallet positioning mechanism for transportation includes: a conveyor frame 1 and a plurality of conveyor rollers 2 disposed within the conveyor frame 1. The conveyor rollers 2 are rotatably disposed within the conveyor frame 1 via a transmission mechanism. The conveyor frame 1 is provided with a positioning mechanism 3, a limiting mechanism 4, and a guiding mechanism 5. The positioning mechanism 3 includes a double-headed cylinder 31 disposed at the lower end of the conveyor frame 1, a connecting frame 32 fixedly disposed at the end of the piston rod of the double-headed cylinder 31, and a positioning frame 33 disposed on the connecting frame 32. The positioning frame 33 is disposed at the upper end of the conveyor rollers 2 and has a guide roller 331 rotatably disposed inside it. The limiting mechanism 4 includes a limiting motor 41, a reduction gearbox 42 operatively connected to the limiting motor 41, and a limiting shaft 43 operatively connected to the reduction gearbox 42. The limiting shaft 43 is disposed between adjacent conveyor rollers 2 and has a limiting plate 431 fixedly disposed on it. The guiding mechanism 5 includes a mounting base 51 fixedly disposed on the conveyor frame 1 and a guide rod 52 slidably disposed on the mounting base 51.

[0022] like Figures 1 to 4 As shown, in actual use, the relative positions of the positioning frame 33 and the guide rod 52 are adjusted sequentially to adapt the spacing between the positioning frames 33 and the guide rod 52 to the size of the pallet. The pallet is then placed on the conveyor roller 2. During transport, the pallet is guided by the guide rollers 331 and the guide rods 52, allowing it to move within a set position and preventing positional deviation. When transported to a designated point, a sensor triggers a signal, causing the limit motor 41 to rotate the limit plate 431 upwards, thus limiting the pallet. Simultaneously, the robotic arm places the product on the pallet within its designated area. After placement, the limit motor 41 reverses, releasing the limit plate 431 from limiting the pallet, allowing the product and pallet to be transported into the irradiation equipment. This reduces potential safety hazards caused by positional deviations, ensures worker safety, helps maintain a more stable production process and product quality, and reduces the risk of physical damage during handling, protecting product integrity.

The two sets of through holes 5121 are vertically arranged and both have expansion joints 5122. Each set of expansion joints 5122 has a threaded hole 5123 through its side end. The mounting block 512 is slidably mounted on the mounting column 511 through the through hole 5121 on the left side. The end of the guide rod 52 is slidably mounted in the through hole 5121 on the right side of the mounting block 512.

[0024] Specifically, a locking bolt is screwed in the threaded hole 5123, and by loosening the locking bolt, the height of the mounting block 512 on the mounting column 511 and the position of the guide rod 52 on the mounting block 512 can be adjusted.
