Detailed Implementation
[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] Reference Figures 1 to 4As shown, this utility model provides a pressing and shaping device for a lithium battery explosion-proof sheet welding machine. In one embodiment, it includes a shaping fixing frame 1, a shaping platform 2 installed inside the shaping fixing frame 1, a shaping transport mechanism 3 installed on one side of the shaping fixing frame 1, and a shaping pressing mechanism 4 installed on the top of the shaping fixing frame 1 and above the shaping platform 2. The shaping platform 2 is also equipped with a shaping fixture 5 for carrying the product. The shaping transport mechanism 3 includes a first Z-axis lifting mechanism 31 connected to one side of the shaping fixing frame 1, and a first Z-axis lifting mechanism 3... 1. A first X-axis translation mechanism 32 is connected, and a shaping translation frame 33 is connected to the first X-axis translation mechanism 32; a shaping transport module is connected to each end of one side of the shaping translation frame 33; the shaping transport module includes a shaping connecting seat 34 connected to one side of the shaping translation frame 33, and a shaping transport rod 35 is connected to each end of the bottom of the shaping connecting seat 34; a plurality of first suction nozzles 36 are installed at intervals along the length of the bottom of the shaping transport rod 35, and a first air source connector communicating with the first suction nozzles 36 is also installed on the top of the shaping transport rod 35.
[0016] Continue to refer to Figures 1 to 4 As shown, in this embodiment, a first transmission device 6 is also included. The first transmission device 6 is arranged on one side of the shaping platform 2, and a first vision inspection mechanism 7 is also arranged on one side of the first transmission device 6. The first vision inspection mechanism 7 includes a vision inspection frame, two industrial cameras mounted on the vision inspection frame, and a light source arranged below each industrial camera. At the same time, a lifting mechanism (including a lifting cylinder, etc.) is arranged at the lower end of the first transmission device 6 near the shaping platform 2. The first transmission device 6 is used to connect to the upstream transmission line to receive the battery top cover after the explosion-proof sheet has been welded. The first transmission device 6 first transmits the battery top cover to the first vision inspection mechanism 7, where it is inspected by the industrial camera. If the inspection is qualified, it is then transmitted to the lifting mechanism. If the inspection is unqualified, it is transferred to the defective product buffer position by an external robot. The lifting mechanism can lift the battery top cover so that the shaping and transporting mechanism 3 can transfer it to the shaping fixture 5. Subsequently, the shaping and pressing mechanism 4 presses down the battery top cover for shaping. After the shaping is completed, the shaping and transporting mechanism 3 then transports it to the downstream transmission line.
[0017] In this embodiment, both the first Z-axis lifting mechanism 31 and the first X-axis translation mechanism 32 adopt existing linear modules, while the shaping and transporting mechanism 3 is provided with two sets of shaping and transporting modules. One shaping and transporting module can transfer the product to the shaping fixture 5 for shaping, while the other shaping and transporting module can transport the shaped product to the downstream transmission line. This seamless working method can ensure the uninterrupted continuous operation of the production line, thereby greatly improving work efficiency. At the same time, each shaping and transporting module is provided with two shaping and transporting rods 35, which can transport two battery top covers at one time, further improving work efficiency.

The extension and retraction of the shaping and pressing electric cylinder 41 can drive the pressing and fixing plate 42 to move up and down, and then the shaping pressing block 45 presses and shapes the battery top cover. The number, shape and size of the shaping pressing block 45 can be adjusted according to the product.
[0019] Preferably, the bottom of the upper adjusting block 43 has a first sliding groove extending to both ends along its length, and each of the inner walls of the first sliding groove has a first slot extending to both ends of the upper adjusting block 43; the top of the upper adjusting block 44 is integrally connected to an upper connecting block 46 with a T-shaped structure, and the T-shaped ends of the upper connecting block 46 are respectively inserted into a first slot; a plurality of first fixing holes are spaced apart along the length of both sides of the upper adjusting block 43. The upper adjusting block 44 can slide within the first sliding groove of the upper adjusting block 43, thereby allowing manual adjustment of the position of the shaping pressure block 45 according to the actual product type, providing strong versatility. After adjusting the position of the shaping pressure block 45, it can be fixed by locking screws into the first fixing holes, making it convenient to use.
[0020] Furthermore, a first guide post 47 is connected to each of the four top corners of the pressing and fixing plate 42, and a first linear bearing is installed on the shaping plate at the corresponding position of the first guide post 47; the upper part of the first guide post 47 passes through the first linear bearing, and a guide post connecting frame 48 is connected between the tops of the four first guide posts 47. Through the cooperation of the first guide posts 47 and the first linear bearings, precise guidance is provided for the up and down movement of the pressing and fixing plate 42, ensuring its stability during lifting and lowering.
[0021] In one embodiment, a shaping fixture 5 is installed on each of the top two sides of the shaping platform 2; the shaping fixture 5 includes two width limiting strips 51 arranged along the length direction of the shaping platform 2, and two length limiting strips 52 arranged along the length direction of the shaping platform 2; the two width limiting strips 51 are arranged in parallel and spaced apart, and the two length limiting strips 52 are respectively arranged at one end between the two width limiting strips 51; a width adjusting block 53 is slidably connected to each of the top two ends of the width limiting strip 51, and a first limiting wheel 54 is also installed on one side of the width adjusting block 53 perpendicular to the length direction of the shaping platform 2; a length adjusting block 55 is slidably connected to the top of each of the length limiting strips 52, and a second limiting wheel 56 is installed on one side of the length adjusting block 55 along the length direction of the shaping platform 2; a second fixing hole is provided on both the width adjusting block 53 and the length adjusting block 55.
[0022] The width limiting strip 51 and the length limiting strip 52 work together to limit, fix, and support the two ends and sides of the battery top cover, ensuring its stability when the shaping and pressing mechanism 4 presses it down. Simultaneously, the positions of the width adjusting block 53 and the length adjusting block 55 can be manually adjusted to accommodate top covers of different sizes, offering high versatility. After adjustment, screws are tightened into the second fixing holes to secure it. Furthermore, a position sensor is installed on the shaping platform 2, positioned between the two length limiting strips 52. The position sensor detects whether the top cover is in place, facilitating backend control of the shaping and pressing mechanism 4 to press and shape the top cover.
