[0003] The production process of in-vehicle products has relatively high requirements for cleanliness. For example, for in-vehicle products such as glass cover plates, during the process of material taking and transportation by production process equipment, the suction rod often wears, that is, the telescopic tube moves up and down and rubs against the main sleeve to generate metal debris. The generated debris will directly fall onto the product, resulting in defects such as foreign objects and dirt on the product. Even some products need to be scrapped or reworked, ultimately affecting the production yield and efficiency of the enterprise.

[0004] Therefore, how to avoid the debris generated by the wear of the suction rod from falling onto the product is an urgent problem to be solved in this field. Content of the Utility Model

[0025] See also Figures 2-3 In this embodiment, a through hole 302 is opened at the center of the inner bottom wall of the material receiving box 3. The size of the through hole 302 is adapted to the size of the threaded tube 201. The material receiving box 3 is sleeved on the rod body of the threaded tube 201 through the through hole 302.

[0026] Specifically, the designed through-hole 302 can facilitate the installation of the material receiving box 3 on the telescopic tube 2, so that the material receiving box 3 can be used to receive the debris.

[0027] See also Figures 2-3 In this embodiment, a fastening nut 3 8 is threadedly sleeved on the surface of the threaded tube 1 201, and the diameter of the fastening nut 3 8 is larger than the aperture of the through hole 302; a sealing ring is also provided at the bottom of the fastening nut 3 8, and the sealing ring is tightly fitted to the inner bottom wall of the receiving box 3 through the fastening nut 3 8.

[0028] Specifically, by designing the fastening nut three 8 and cooperating with the sealing ring designed at the bottom, it is beneficial to use the fastening nut three 8 to fix the inner bottom wall of the docking material box 3, and indirectly block the through hole 302 through the sealing ring, thereby preventing debris from entering the through hole 302.

[0029] See also Figure 2, in this embodiment, the top of the suction cup 7 is threadedly connected to the bottom of the second threaded pipe 202, and the top of the suction cup 7 is closely attached to the bottom of the receiving box 3.

[0030] Specifically, on the one hand, the suction cup 7 can adsorb the product, and on the other hand, by tightening the suction cup 7, the bottom of the receiving box 3 can be fixed, thereby ensuring the stability of the receiving box 3.

[0031] Please refer to Figures 1-2 , in this embodiment, the edge at the top of the receiving box 3 is designed as an arc structure that bends outward, and the receiving box 3 is made of transparent plastic.

A cylinder device (not shown in the figure) is also connected to the adjusting plate 4. When the power output shaft of the cylinder device makes a telescopic movement, the position of the main sleeve 1 on the telescopic tube 2 can be changed.

[0037] When installing the material receiving box 3, first unscrew the suction cup 7 from the bottom of the second threaded pipe 202, screw up the third fastening nut 8, then insert the material receiving box 3 from the bottom of the second threaded pipe 202, so that the second threaded pipe 202 enters the through hole 302, and lift the material receiving box 3 upward to make the through hole 302 of the material receiving box 3 close to the first threaded pipe 201. Then, screw the suction cup 7 tightly at the bottom of the second threaded pipe 202 again, and screw down the third fastening nut 8, so that the sealing ring at the bottom of the third fastening nut 8 fits precisely on the inner bottom wall of the material receiving box 3, and finally fix the material receiving box 3 firmly between the bottom of the third fastening nut 8 and the top of the suction cup 7;

[0038] When the telescopic pipe 2 expands and contracts inside the main sleeve 1, the debris generated by friction and wear can fall into the material receiving box 3, preventing the debris from falling on the product adsorbed by the suction cup 7 and ensuring the cleanliness of the product.
