[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the embodiment, Figure 1-4 An automatic ear pinching mechanism for a cast welding machine is provided, comprising a stand 1, two push assemblies 2 for pushing the lead-acid battery casing are provided on the stand 1, a lifting assembly 3 is provided on the stand 1, a pinching assembly 4 for pinching the pole group is provided at the bottom end of the lifting assembly 3, and a translation assembly 5 for translating the pinching assembly 4 is provided on the lifting assembly 3;

[0023] The lifting assembly 3 includes a lifting cylinder 31, which is fixedly connected to the stand 1. A lifting cylinder push rod 32 is slidably connected to the inner side of the lifting cylinder 31. The bottom end of the lifting cylinder push rod 32 is fixedly connected to the lifting seat 33. Four guide sleeves 34 are fixedly connected to the inner side of the stand 1. The inner sides of the four guide sleeves 34 are all slidably connected to guide rods 35. The four guide rods 35 are all fixedly connected to the top of the lifting seat 33.

[0024] The ear pinching assembly 4 includes a slide rail 41, the bottom end of the lifting seat 33 is fixedly connected to the slide rail 41, the outer side of the slide rail 41 is slidably connected to two sliders 42, the bottom ends of the two sliders 42 are fixedly connected to the connecting plate 43, and the bottom end of the connecting plate 43 is fixedly connected to several ear pinching columns 44.

[0025] Through the above settings, the stand 1 is installed above the conveyor belt of the cast welding machine. When the conveyor belt transfers the battery shell (the pole group has been inserted into the battery shell at this time) to the pushing assembly 2, the conveyor belt stops transmitting, and the pushing assembly 2 pushes the battery pack to the bottom of the connecting plate 43, and starts the translation assembly 5. The translation assembly 5 drives the connecting plate 43 to translate to the left or right. At this time, the two sliders 42 slide to the left or right along the outside of the slide rail 41, and the positions of several pinching columns 44 are fine-tuned so that several pinching columns 44 are located just above each pole piece of the pole group. The lifting cylinder 31 is started, the lifting cylinder push rod 32 is pushed out, and the lifting seat 33 moves downward. At this time, the four guide rods 35 slide along the inner side of the four guide sleeves 34, and several pinching columns 44 are squeezed downward to bend all the pole pieces, thereby completing the pinching operation.

[0026] Reference Figure 1-4The push assembly 2 includes a fixed seat 21, the fixed seat 21 is fixedly connected to the stand 1, the top of the fixed seat 21 is fixedly connected to the push cylinder 22, the inner side of the push cylinder 22 is slidably connected to the push cylinder push rod 23, and the end of the push cylinder push rod 23 located on the outer side of the push cylinder 22 is fixedly connected to the L-shaped push plate 24;

[0027] Through the above settings, when the conveyor belt transports the battery casing (the electrode group has been inserted into the battery casing at this time) to the vicinity of the L-shaped push plate 24, the push cylinder 22 is started, the push cylinder push rod 23 is pushed out, and the L-shaped push plate 24 is pushed out to push the battery casing to the bottom of the ear pinching component 4. The short end of the L-shaped push plate 24 can play a limiting role to prevent the battery casing from moving.

[0029] Through the above-mentioned structural arrangement, the translation cylinder 52 is started, and the translation cylinder push rod 53 is pushed out or retracted, thereby driving the translation connecting rod 54 to move rightward or leftward, and further causing the connecting plate 43 to move rightward or leftward.
