[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figures 1 to 3As shown, in this embodiment, a welding block positioning mechanism for a half-cell battery includes a welding block feeding rail 1 and a welding block adjusting frame 2, the two ends of the welding block feeding rail 1 are rotatably connected with a welding block feeding main wheel 3 and a welding block feeding slave wheel 4, a welding block feeding belt 5 is drivingly connected between the welding block feeding main wheel 3 and the welding block feeding slave wheel 4, a welding block adjusting plate 6 is movable along the front and rear directions on the welding block adjusting frame 2, both sides of the welding block adjusting plate 6 are inserted into the welding block feeding belt 5, a first welding block adjusting baffle 7 is arranged on one side of the welding block adjusting plate 6, a striker 8 and a spring pin 9 are fixed to the front end of the first welding block adjusting baffle 7, a second welding block adjusting baffle 10 is arranged on the other side of the welding block adjusting plate 6, a welding block positioning cylinder 11 is fixed to the outer side of the second welding block adjusting baffle 10, and a welding block pushing block 12 is connected to the driving end of the welding block positioning cylinder 11.

[0020] The welding block is on the welding block feeding rail 1, and the welding block feeding main wheel 3 and the welding block feeding slave wheel 4 rotate in coordination, and the welding block feeding belt 5 drives the welding block to move. When the welding block needs to stop, the welding block adjusting plate 6 is adjusted to that position. When the welding block arrives, it will touch the spring pin 9, so that the spring pin 9 contacts the striker 8, thereby controlling the welding block feeding belt 5 to stop. Then the welding block positioning cylinder 11 controls the welding block pushing block 12 to push the welding block to the position of the first welding block adjusting baffle 7, thereby positioning it between the positions of the first welding block adjusting plate 6 and the second welding block adjusting plate 6. If the final position of the welding block needs to be adjusted, the welding block adjusting plate 6 is controlled to move back and forth, which is simple and convenient.

[0021] A welding block adjusting motor 13 is fixed on the welding block adjusting frame 2, and a welding block adjusting screw rod 14 is connected to the driving end of the welding block adjusting motor 13. The bearing of the welding block adjusting screw rod 14 is connected to the welding block adjusting frame 2, and a welding block adjusting gong nut 15 is fixed to the lower end of the welding block adjusting plate 6. The welding block adjusting screw rod 14 is threadedly connected to the welding block adjusting gong nut 15. The welding block adjusting motor 13 drives the welding block adjusting plate 6 with the welding block adjusting gong nut 15 to move forward and backward by controlling the rotation of the welding block adjusting screw rod 14.

[0022] A welding block adjustment rail 16 is fixed to the upper end of the welding block adjustment frame 2, and a welding block adjustment slider is fixed to the lower end of the welding block adjustment plate 6. The welding block adjustment slider slides on the welding block adjustment rail 16. In the process of the welding block adjustment plate 6 moving back and forth, the sliding between the welding block adjustment rail 16 and the welding block adjustment slider not only reduces the friction caused by the movement of the welding block adjustment plate 6, but also plays a guiding role.

[0023] Solder block sensors 17 are installed on both sides of the middle section of the solder block feeding rail 1 , and the solder block sensors 17 sense whether the solder block passes through the solder block feeding rail 1 .

[0024] An anti-drop plate 18 is fixed in the middle of the welding block feeding rail 1. In order to prevent the welding block from falling off the welding block feeding rail 1 during the movement of the welding block, the anti-drop plate 18 is added to catch the welding block that is about to fall.

[0025] A welding block moving motor 19 is installed on one side of the welding block feeding rail 1, and a welding block feeding shaft 20 is connected between the two welding block feeding main wheels 3. The driving end of the welding block moving motor 19 is transmission-connected to the welding block feeding shaft 20. In the conveying structure of the welding block feeding rail 1, the welding block moving motor 19 controls the rotation of the welding block feeding shaft 20, and the welding block feeding shaft 20 drives the welding block feeding main wheels 3 at both ends to rotate, thereby driving the welding block feeding belt 5 to drive the welding block to move.

[0026] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
