Technical Field

[0001] This utility model relates to the field of positioning and locking technology, and in particular to a positioning and locking device for a string welding machine material box. Background Technology

[0002] String welding machines primarily utilize the coordinated operation of mechanical, electrical, and pneumatic systems to automatically weld multiple solar cells into a string according to a specific arrangement. Common welding methods include infrared heating welding and laser welding. Taking infrared heating welding as an example, the infrared heating source in the equipment rapidly heats the welding area of ​​the solar cells, causing the welding ribbon to form a strong alloy bond with the metal electrodes on the surface of the solar cells at high temperatures, thereby achieving electrical connection between the solar cells.

[0003] In the prior art, such as Chinese Patent CN 220030003 U, a positioning and locking device for a string welding machine hopper includes a positioning component and a locking component. The positioning component is used to position one side of the hopper and includes a first bracket and a positioning element. The positioning element includes a positioning body and a positioning platform. The positioning body abuts against the side wall of the groove on one side of the hopper, and the positioning platform abuts against the upper surface of the hopper. The locking component is used to fix the other side of the hopper and includes a second bracket, a driving element, and a locking element. The driving element includes a driving body and a driving shaft. Both the driving body and the driving shaft extend upwards at an angle away from the base. The driving body is rotatably connected to the lower side of the second bracket. The upper end of the locking element has a locking part that abuts against the bottom wall of the groove on the other side of the hopper. The lower end of the locking element has a first connection point rotatably connected to the driving shaft and a second connection point rotatably connected to the upper side of the second bracket. The device provided by this utility model prevents the hopper from tilting and tipping over after impact and firmly locks the hopper. However, this patent still has the following problems.

[0004] In the aforementioned patent, although a positioning component is provided to effectively prevent the material box from tilting and tipping over after impact, the position of the positioning platform and the position of the positioning rod are fixed. Therefore, for material boxes of other sizes, the positioning and locking components may not fit tightly enough with the material box or there may be an interference fit, which will affect the positioning and locking effect and the service life of the material box. Utility Model Content

[0005] This utility model mainly provides a positioning and locking device for a string welding machine material box that facilitates improved positioning efficiency and prevents interference with positioning and locking.

[0024] like Figure 2 and Figure 4 As shown, an L-shaped plate 8 is provided at the end of the material box body 1 away from the positioning rod 12. The L-shaped plate 8 is located on the side wall of the base plate. A first electric telescopic rod 9 is fixedly installed at the bottom of the L-shaped plate 8. The telescopic end of the first electric telescopic rod 9 passes through the L-shaped plate 8 and is fixedly installed with a connecting plate 10. A slot 20 is opened on the outer wall of the connecting plate 10. A limiting groove 21 is opened on the inner wall of the slot 20. A spring 22 is fixedly installed on the inner wall of the limiting groove 21. A locking block 23 is fixedly installed at the bottom of the spring 22. A connecting rod 24 is fixedly installed at the top of the locking block 23. The top of the connecting rod 24 passes through the limiting groove 21 and is fixedly installed with a pull plate 25. When the operator starts the first electric telescopic rod 9, the pressure plate 11 descends and contacts the inner wall of the fixing groove 7, locking the material box body 1.

[0025] like Figure 4 As shown, the insert plate 18 is slidably installed inside the slot 20, and the top of the insert plate 18 has a through slot 19. The outer wall of the insert plate 18 is fixedly installed with a pressure plate 11. The insert plate 18 is slidably connected to the slot 20, and the card block 23 is slidably connected to the slot 19.

[0026] like Figure 1 As shown, fixing grooves 7 are provided on all four sides of the material box body 1. When the pressure plate 11 descends and contacts the inner wall of the fixing groove 7, the material box body 1 can be locked.

[0027] like Figure 3 As shown, top plates 16 are fixedly installed on the top of both positioning rods 12 to prevent the abutment plate 15 from leaving the positioning rods 12.

[0028] like Figure 1 and Figure 3As shown, the outer wall of the positioning rod 12 fits against the inner wall of the positioning groove 6 to prevent affecting the stability of the positioning.
