[0002] With the improvement of people's living standards and the current trend of environmental protection, energy conservation, and a green ecological earth, new energy vehicles, with the strong support of the country, are growing stronger and stronger and are being used more and more widely. The batteries that match new energy vehicles are also developing rapidly accordingly. The battery pack is an important component of the battery. It determines the operating environment of the battery module and thus affects the battery life. However, the battery pack production process is complicated, and different processes generally need to be operated at different workstations. Therefore, during the continuous processing of multiple processes, the workpiece needs to be changed and repositioned multiple times, which will seriously affect the production efficiency and positioning accuracy of the battery pack.

[0030] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0031] like Figures 1 to 4 As shown, this embodiment provides a battery pack shaping and trimming device, comprising a lower die shaping block 1 for fixing the workpiece and an upper die shaping block 2 for reciprocating on the lower die shaping block 1 and shaping the workpiece.

[0032] The lower mold shaping block 1 includes: a base plate 11 and a product positioning block 12 and a guide column seat 13 arranged on the base plate 11, a guide column 131 is provided on the guide column seat 13, and a waste slag middle hole 14 is provided in the product positioning block 12 that passes through the upper and lower parts; the base plate 11 is provided with an opening below the waste slag middle hole 14.

[0033] The upper mold shaping block 2 includes: a top plate 21, a pressure plate 22, a knife edge plate 23 and a pressure block 24. A support plate 25 is provided between the top plate 21 and the pressure plate 22. The pressure plate 22 is slidably connected to an inner guide column 29 fixedly provided between the knife edge plate 23 and the top plate 21. The pressure plate 22 and the pressure block 24 are fixedly connected by a connecting rod 26 provided through the knife edge plate 23. The position of the pressure block 24 corresponds to the upper and lower sides of the product positioning block 12. A knife edge 2 is provided below the knife edge plate 23 corresponding to the outer side of the pressure block 24. 31, the blade 231 is arranged around the shaping area, and the blade 231 is provided with a burr segmentation, and the blade 231 is a detachable blade; a guide sleeve seat 27 is also provided at the bottom of the blade plate 23, and a guide sleeve 271 corresponding to the guide column 131 of the guide column seat 13 is provided at the bottom of the guide sleeve seat 27; an elastic member 28 is also provided between the pressing plate 22 and the top plate 21, and the elastic member 28 is a nitrogen spring; the pressing block 24 is divided into several shaping areas, and the waste slag middle hole 14 on the product positioning block 12 is provided corresponding to the shaping area.

[0034] An ejection block is provided on the top plate 21 at a position corresponding to the elastic member 28 . When the upper mold shaping block 2 and the lower mold shaping block 1 are at the third limit position, the elastic member 28 ejects the ejection block.

[0035] The pressing plate 22 is provided with a pressure signal sensor for receiving a signal indicating that the pressing plate 22 is in position.

[0036] A level detection device 3 is provided on the product positioning block 12 for performing level detection on the product on the product positioning block 12. The level detection device 3 includes at least two groups and is arranged at the corners of the product positioning block 12. The diagonally arranged level detection devices 3 constitute one group.

[0037] When the guide sleeve seat 27 and the guide column seat 13 are not in contact, it is the first limit position;

[0038] The second limit position is when the guide sleeve seat 27 contacts the guide post seat 13, the guide post 131 has not fully entered the guide sleeve 271, and the pressing block 24 contacts the product fixed on the product positioning block 12;

[0039] The guide post 131 completely enters the guide sleeve 271, the blade plate 23 moves downward on the connecting rod 26 relative to the pressing plate 22, and the pressing plate 22 moves upward on the inner guide post 29 relative to the top plate 21. When the elastic member 28 between the pressing plate 22 and the top plate 21 is compressed, it reaches the third limit position, at which time the elastic member 28 pushes the ejection block out;

[0040] The upper mold shaping block 2 and the lower mold shaping block 1 move between a first limit position, a second limit position and a third limit position.

[0041] The working process of the entire battery pack shaping and trimming device is as follows: the product is placed on the product positioning block 12 by the robot, and the upper mold shaping block 2 is pressed down by the hydraulic press, so that the upper mold shaping block 2 and the lower mold shaping block 1 enter the first extreme position, the second extreme position and the third extreme position in turn. After the shaping and trimming are completed, the upper mold shaping block 2 is pushed back upward, and the product falls into the opening in the bottom plate 11. After the product is taken out by the robot, the upper mold shaping block 2 and the lower mold shaping block 1 are cleaned by blowing air around them, and the cycle operation is repeated.

[0042] By setting the upper and lower mold shaping blocks 1, the product can be shaped and trimmed quickly and effectively, and the guide sleeve seat 27 and the guide column seat 13 set on the shaping block are limited. During the downward pressing process of the upper mold shaping block 2, the knife edge 231 set on the pressing block 24 can quickly shape the product, ensuring high efficiency during the continuous processing process.

[0043] By ejecting the ejection block through the elastic member 28, a signal that the product shaping and trimming is completed can be quickly obtained. The whole process is coherent and fast, and the ejection block can quickly determine that the product shaping is completed. After the ejection block is ejected, the finished product is quickly withdrawn and the next round of shaping is continued.

[0044] By setting a corresponding waste slag middle hole 14 in the lower mold shaping block 1 and providing a burr segmentation on the blade 231, it can fall smoothly after completing the shaping and trimming, ensuring the blanking speed during processing, and the blade 231 on the blade plate 23 used for shaping and trimming in the shaping area adopts a detachable blade 231, which is easy to replace separately, reducing the time lost in replacing the entire tool holder and improving production efficiency. The overall setting of this application makes the entire shaping and trimming process efficient and fast, and the positioning is accurate, greatly improving production efficiency while ensuring accuracy.

[0045] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present invention specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of patent protection of the present invention.
