This is a mature existing technology and will not be described in detail here;

[0020] It also includes a support frame 3, on both sides of which a feed conveyor belt 4 and a discharge conveyor belt 5 are respectively arranged, and two translation platforms 6 are slidably matched on the support frame 3, and a translation mechanism 7 is arranged between the feed conveyor belt 4, the discharge conveyor belt 5 and the adjacent translation platforms 6, and a stop block is fixedly arranged at one end of the feed conveyor belt 4 close to the translation platform 6, and a flipping mechanism 8 is arranged between the two translation platforms 6, and the translation platform 6 is connected to a driving mechanism so that the translation platform 6 has a first position and a second position relative to the spot welding head. When the translation platform 6 is located at the first position, it is used to receive the jig transferred by the translation mechanism 7 and the flipping mechanism 8, and when the translation platform 6 is located at the second position, the jig is located below the spot welding head for spot welding.

[0021] Four positioning blocks 9 are fixedly provided on the translation stage 6. Positioning grooves for placing the jig are formed on the inner sides of the four positioning blocks 9 to facilitate positioning of the jig after transfer and avoid displacement of the jig on the translation stage 6 to affect the spot welding quality.

[0022] The translation mechanism 7 includes a first mounting frame 701, the top of the first mounting frame 701 is rotatably connected to a screw rod 702 through a bearing, one end of the screw rod 702 is fixedly connected to a translation motor for driving the screw rod 702 to rotate, a translation block 703 is threadedly sleeved on the screw rod 702, the rotation of the screw rod 702 drives the translation block 703 to translate left and right along the screw rod 702, a movable block 704 is slidably connected to the translation block 703, and a lifting cylinder (not shown in the figure) is provided on the translation block for driving the movable block to lift and lower, and a first pneumatic clamp 705 is fixedly provided on the movable block.

[0023] The translation mechanism 7 also includes a limit rod 706 arranged parallel to the screw rod 702. The limit rod 706 is fixedly connected to the first mounting frame 701. A limit hole is opened on the translation block 703 for the limit rod 706 to pass through. The inner wall of the limit hole is in contact with the outer wall of the limit rod 706.

[0027] Working principle: When in use, when the driving mechanism drives the translation table a601 and the translation table b602 to move from the second position to the first position, the feed conveyor belt 4 conveys the jig loaded with the battery pack to be spot-welded close to the translation table a601 until it is blocked by the stop block, so that the first pneumatic clamp 704 can just move downward to clamp the jig onto the translation table a601, and the second pneumatic clamp 803 flips the jig on the translation table a601 180 degrees and places it on the translation table b602. The jig loaded with the spot-welded battery pack on the translation table b602 is translated to the discharge conveyor belt 5, and is sent away from the spot welding station by the discharge conveyor belt 5, replacing the traditional operation method, avoiding the tedious manual operation, reducing labor costs, and improving production efficiency.
