Description

Technical Field

[0001] This invention relates to the field of energy storage battery component processing technology, and in particular to an upper plate processing device for energy storage battery cover plates. Background Technology

[0002] The cover plate of an energy storage battery is an important component of the battery. As the housing structure for the energy storage batteries in new energy vehicles, it needs to accommodate multiple battery modules. Therefore, the cover plate must have high sealing performance, structural strength, and corrosion resistance. Its processing quality directly affects the overall performance and service life of the energy storage battery. In the processing of the energy storage battery cover plate, the loading step is a key step connecting the conveying equipment and the processing equipment. It is necessary to ensure that the cover plate is transferred smoothly and accurately to the processing station.

[0003] Existing battery cover plate feeding equipment used in energy storage battery processing often faces the problem of mismatch between the cover plate conveying speed and the processing equipment speed during the battery cover plate processing process. Traditional feeding equipment has a relatively simple structure, usually only realizing the basic cover plate conveying function, making it difficult to accurately control and flexibly adjust the conveying speed. When the conveying equipment speed is too fast, the cover plates are prone to accumulate at the inlet of the processing equipment, causing equipment blockage and affecting the normal production order; while when the conveying equipment speed is too slow, the processing equipment will wait for the cover plates, making it impossible to properly connect the conveying equipment and the processing equipment, affecting the continuity of the entire production process, and increasing the uncertainty and error rate in the production process. Therefore, this application provides a feeding equipment for energy storage battery cover plate processing to meet the requirements. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an upper plate processing device for energy storage battery cover plates.

[0005] To achieve the above objectives, this application provides the following technical solution: a plate-mounting device for processing energy storage battery cover plates, comprising a frame and a first carrier plate fixed inside the frame, wherein a stand is fixed on the surface of the first carrier plate, and a movable plate distributed along the plane direction is provided on one side of the stand.

[0006] The support extends horizontally to form multiple first extension beams with a comb-like structure, and multiple second extension beams with a comb-like structure are fixed on the movable plate. When the movable plate moves to below the first extension beams, the second extension beams and the first extension beams are spliced ​​together to form a planar structure that accommodates the energy storage battery cover.

[0007] Two sets of transfer suction cups that can move horizontally and vertically synchronously are provided above the first carrier plate. When the two sets of transfer suction cups move the two energy storage battery cover plates outside the frame to the surface of the second extension beam and the first extension beam in the spliced ​​state, the two energy storage battery cover plates are moved to the outside of the frame as the moving plate and the second extension beam move horizontally synchronously.

[0008] Furthermore, a first follower frame is fixed to the bottom of the movable plate, and a first rack assembly arranged in a straight line is fixed to the inner side of the first follower frame. A first drive gear is meshed with one side of the first rack assembly. The first drive gear is mounted on the first carrier plate, and a first driver for driving the first drive gear to rotate is assembled on the first carrier plate.

[0009] A slide rail is fixed on the first carrier plate, and the first follower frame is slidably assembled with the slide rail. As the first drive gear rotates, the first rack assembly, the first follower frame, the moving plate, and the second extension beam move synchronously.

[0010] Furthermore, a second carrier plate is fixed inside the frame, and a feeding plate distributed along the plane is provided below the second carrier plate. Connecting seats are fixed on both sets of transfer suction cups, and both connecting seats are located in the relative space between the feeding plate and the first extension beam.

[0011] Furthermore, a second follower frame is fixed to the top of the feeding plate, and a second rack assembly arranged in a straight line is fixed to the inner side of the second follower frame. A second drive gear is meshed with one side of the second rack assembly. The second drive gear is mounted on the second carrier plate, and a second driver for driving the second drive gear to rotate is assembled on the second carrier plate.

[0012] The second carrier plate is fixed with a slide rail two, and the second follower frame is slidably assembled with the slide rail two. As the second drive gear rotates, the second rack group, the second follower frame, the loading plate, the connecting seat and the two sets of transfer suction cups move synchronously.

[0013] Furthermore, two sets of third linear cylinder modules are installed on the feeding plate. The output ends of the third linear cylinder modules are respectively assembled with two connecting seats. As the third linear cylinder modules operate, the two connecting seats carrying two sets of transfer suction cups move up and down.

[0014] Furthermore, the upright base is fixed with docking frames on both sides of the frame. Each docking frame has two first limiting supports of the same specification on the side facing the first extension beam. Each docking frame is equipped with two sets of first linear cylinder modules that can control the movement of the first limiting supports respectively.

[0015] Furthermore, the movable plate is fixed with a positioning frame on both sides facing the frame. The positioning frame has a channel for accommodating the docking frame. The positioning frame has two second limiting supports of the same specification on the side facing the second extension beam. The positioning frame is also equipped with two sets of second linear cylinder modules that can control the movement of the second limiting supports respectively. When the second extension beam and the first extension beam are spliced ​​together to form a planar structure for accommodating the energy storage battery cover, the docking frame is located inside the channel opened on the positioning frame, and the two sets of second limiting supports are located above the two sets of first limiting supports respectively.

[0016] Furthermore, both the first limiting bracket and the second limiting bracket are isosceles trapezoidal frame structures, and the openings of the first limiting bracket and the second limiting bracket face the direction of the first extension beam and the second extension beam, respectively.

[0017] Furthermore, the first limiting support and the second limiting support are respectively equipped with a first limiting roller group and a second limiting roller group in the two symmetrically distributed inclined side frames.

[0018] In summary, the technical effects and advantages of this invention are as follows: 1. This invention enables the storage and transportation of energy storage batteries, allowing the device to act as a transfer point for the energy storage battery cover. This allows the moving speed of the energy storage battery cover to adapt to the operating speed of the conveying and processing equipment, balancing the difference in operating speed between the conveying and processing equipment. This ensures the continuity and stability of the entire production process, avoids production interruptions or efficiency reductions caused by equipment speed mismatches, and reduces the error rate during equipment operation.

[0019] 2. Based on the cooperative use of the first and second extension beams in this device, the frequency of the two energy storage battery covers being moved to the inside of the frame and removed from the frame can be controlled according to the needs of different production rhythms, which greatly improves the flexibility and overall efficiency of the production line, reduces the complexity and error rate of manual operation, and further improves the automation level of the entire production process.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Reference Figure 1 - Figure 3 The illustrated equipment for processing energy storage battery cover plates includes a frame 1 and a first carrier plate 2 fixed inside the frame 1. A support 3 is fixed to the surface of the first carrier plate 2, and a movable plate 5 distributed along a planar direction is provided on one side of the support 3. In actual operation, a conveying device for continuously transporting energy storage battery cover plates is provided on one side of the frame 1, and a processing device for processing the energy storage battery cover plates is provided on the other side. The energy storage battery cover plates, after being conveyed by the conveying device, need to enter the frame 1 before being moved to the processing device.

[0035] Specifically, such as Figure 7 , Figure 8 As shown, multiple first extension beams 4 with a comb-like structure extend horizontally from the base 3, and multiple second extension beams 6 with a comb-like structure are fixed on the movable plate 5. When the movable plate 5 moves below the first extension beams 4, the second extension beams 6 and the first extension beams 4 are joined to form a planar structure for accommodating the energy storage battery cover. This planar structure can serve as a transfer structure for the energy storage battery cover, and can store two energy storage battery cover plates at a time.

[0036] like Figure 4 As shown, two sets of transfer suction cups 10, capable of synchronous lateral and vertical movement, are provided above the first carrier plate 2. During the transport of the energy storage battery cover, as the conveyor operates, the energy storage battery cover can be successively transferred to one side of the frame 1. After the two sets of transfer suction cups 10 move the two energy storage battery cover conveyed on the conveyor to the surface of the second extension beam 6 and the first extension beam 4 in the spliced ​​state, the two energy storage battery cover are moved to the outside of the frame 1 with the synchronous lateral movement of the moving plate 5 and the second extension beam 6. At this time, the mechanical suction cup structure in the processing equipment can move the two energy storage batteries into the processing equipment to carry out the processing operation of the energy storage battery cover.

[0037] Throughout the process, the storage and transportation of energy storage batteries enable the device to act as a transfer point for the energy storage battery cover, allowing the moving speed of the energy storage battery cover to adapt to the operating speed of the conveying and processing equipment. This balances the differences in operating speed between the conveying and processing equipment, ensuring the continuity and stability of the entire production process. It avoids production interruptions or efficiency reductions caused by equipment speed mismatches, while also reducing the error rate during equipment operation and minimizing the frequency of manual adjustments to the equipment to accommodate errors.

[0038] Meanwhile, based on the splicing distribution of the first extension beam 4 and the second extension beam 6, they can be made to not interfere with each other. When the moving plate 5 in this device, carrying the second extension beam 6 and two energy storage battery cover plates, moves to the outside of the frame 1, the two sets of transfer suction cups 10 can again pick up the two energy storage battery cover plates from the conveying equipment and transfer them to the first extension beam 4. At this time, although the moving plate 5 and the second extension beam 6 are located outside the frame 1, and the processing equipment is transferring the two energy storage battery cover plates on the second extension beam 6, after the energy storage battery cover plates are transferred into the processing equipment, the moving plate 5 can immediately return to the bottom of the first extension beam 4, so that the second extension beam 6 is spliced ​​with the first extension beam 4 again to form a new planar structure for accommodating the energy storage battery cover plates. The moving plate 5 and the second extension beam 6 can then move the two energy storage battery cover plates to the outside of the frame 1 again, so that the processing equipment can transfer the energy storage battery cover plates, thereby realizing the continuous and efficient transfer of energy storage battery cover plates.

[0039] Based on the coordinated use of the first extension beam 4 and the second extension beam 6 in this device, the frequency at which the two energy storage battery covers are moved to the inside of the frame 1 and removed from the inside of the frame 1 can be controlled according to the needs of different production rhythms, which greatly improves the flexibility and overall efficiency of the production line, reduces the complexity and error rate of manual operation, and further improves the automation level of the entire production process.

[0040] like Figure 3 As shown, the comb-like structure of the first extension beam 4 and the second extension beam 6 also increases the stability and reliability of their splicing, preventing the energy storage battery cover from shaking during movement and improving the safety and accuracy of the energy storage battery cover during transfer.

[0041] like Figure 5 , Figure 6 As shown, a first follower frame 51 is fixed at the bottom of the movable plate 5. A first rack group 52 arranged in a straight line is fixed inside the first follower frame 51. A first drive gear 53 is meshed on one side of the first rack group 52. The first drive gear 53 is mounted on the first carrier plate 2. A first driver 54 for driving the first drive gear 53 to rotate is mounted on the first carrier plate 2.

[0042] A slide rail 21 is fixed on the first carrier plate 2, and the first follower frame 51 is slidably assembled with the slide rail 21. During operation, the first driver 54 drives the first drive gear 53 to rotate, thereby causing the first rack assembly 52, the first follower frame 51, the moving plate 5, and the second extension beam 6 to move synchronously along the distribution path of the slide rail 21. This achieves the purpose of moving and transporting the energy storage battery cover and moving it to its reset position.

[0043] like Figure 9 , Figure 10As shown, in order to enable the two sets of transfer suction cups 10 to move smoothly horizontally and vertically, in this device, a second carrier plate 7 is fixed inside the frame 1, and a feeding plate 8 distributed along the plane direction is provided below the second carrier plate 7. A connecting seat 9 is fixed on each of the two sets of transfer suction cups 10, and the two connecting seats 9 are located in the relative space between the feeding plate 8 and the first extension beam 4.

[0044] Specifically, such as Figure 10 As shown, a second follower frame 81 is fixed at the top of the feeding plate 8, and a second rack group 82 arranged in a straight line is fixed inside the second follower frame 81. A second drive gear 83 is meshed on one side of the second rack group 82. The second drive gear 83 is mounted on the second carrier plate 7, and a second driver 84 for driving the second drive gear 83 to rotate is mounted on the second carrier plate 7.

[0045] like Figure 9 As shown, a second slide rail 71 is fixed on the second carrier plate 7, and the second follower frame 81 is slidably assembled with the slide rail 71. During operation, the second driver 84 drives the second drive gear 83 to rotate, thereby causing the second rack assembly 82, the second follower frame 81, the loading plate 8, the connecting seat 9, and the two sets of transfer suction cups 10 to move synchronously along the distribution path of the slide rail 71, so as to drive the two sets of transfer suction cups 10 to move laterally. It is worth noting that the movement direction of the two sets of transfer suction cups 10 is opposite to the movement direction of the moving plate 5.

[0046] Furthermore, such as Figure 11 As shown, two sets of third linear cylinder modules 85 are installed on the feeding plate 8. The output ends of the third linear cylinder modules 85 are respectively assembled with two connecting seats 9. As the third linear cylinder modules 85 operate, the two connecting seats 9, equipped with two sets of transfer suction cups 10, move up and down, allowing the two sets of transfer suction cups 10 to adjust their height according to actual needs, so as to more accurately adsorb and place the energy storage battery cover. This design enhances the flexibility and adaptability of the device, enabling it to handle energy storage battery covers of different sizes and shapes, further improving production efficiency and product quality.

[0047] Example 2: As Figure 7 As shown, when the two energy storage battery covers are moved to the surface of the first extension beam 4, in order to ensure the accuracy of the cover position distribution, in this device, the support 3 is fixed with docking frames 31 on both sides of the frame 1. The docking frame 31 is provided with two first limit supports 32 of the same specification on the side facing the first extension beam 4, and two sets of first linear cylinder modules 34 that can control the movement of the first limit supports 32 are installed on the docking frame 31 respectively.

[0048] As the first linear cylinder module 34 operates, the two sets of first limiting supports 32 can move towards the first extension beam 4 respectively, limiting and aligning the energy storage battery cover plate placed on the surface of the first extension beam 4 to ensure its position accuracy and avoid deviation during subsequent movement and processing, which would affect production quality.

[0049] like Figure 8 As shown, the movable plate 5 is fixed with a positioning frame 55 on both sides of the frame 1. The positioning frame 55 has a channel to accommodate the docking frame 31. The positioning frame 55 has two second limit supports 56 of the same specification on the side facing the second extension beam 6. The positioning frame 55 is also equipped with two sets of second linear cylinder modules 58 that can control the movement of the second limit supports 56 respectively. When the second extension beam 6 and the first extension beam 4 are spliced ​​to form a planar structure to accommodate the energy storage battery cover, the docking frame 31 is located inside the channel opened on the positioning frame 55. The two sets of second limit supports 56 are located above the two sets of first limit supports 32 respectively and are in an overlapping state. Since the energy storage battery cover is actually a complete cover structure with a certain height on its side, the first limit supports 32 and the second limit supports 56 can contact it, and their operation does not interfere with each other.

[0050] Specifically, when the moving plate 5, carrying the second extension beam 6 and two energy storage battery covers, moves to the outside of the frame 1, the second linear cylinder module 58 enables the two sets of second limiting supports 56 to move towards the second extension beam 6 respectively, limiting the two energy storage battery covers placed on the surface of the second extension beam 6. This further ensures that the energy storage battery covers can move synchronously and stably with the movement of the second extension beam 6, preventing them from sliding or shifting during the movement, and providing a reliable guarantee for subsequent processing operations.

[0051] Based on Embodiment 1, when the movable plate 5 in this device, carrying the second extension beam 6, two sets of second limiting supports 56, and two energy storage battery covers, moves to the outside of the frame 1, if the two sets of transfer suction cups 10 have once again picked up the two energy storage battery covers from the conveying equipment and transferred them to the first extension beam 4, in this embodiment, the two sets of first limiting supports 32 located above the first extension beam 4 will once again straighten and limit the energy storage battery covers on the surface of the first extension beam 4.

[0052] Subsequently, during the repositioning and re-transfer of the energy storage battery cover by the moving plate 5, since the first limiting support 32 has already positioned the energy storage battery on the surface of the first extension beam 4, the time required for the second limiting support 56 to position the energy storage battery cover during subsequent transfers can be reduced, thereby improving the efficiency of the entire production process. This dual-limiting design not only enhances the stability of the energy storage battery cover during movement but also optimizes the production rhythm through phased limiting, enabling the device to adapt more quickly to the needs of different production stages.

[0053] Example 3: Based on Example 2, such as Figure 7 , Figure 8 As shown, both the first limiting bracket 32 ​​and the second limiting bracket 56 are isosceles trapezoidal frame structures, and the openings of the first limiting bracket 32 ​​and the second limiting bracket 56 face the first extending beam 4 and the second extending beam 6, respectively. The isosceles trapezoidal frame structure reduces the probability of collision between the first limiting bracket 32 ​​and the second limiting bracket 56 and the surface of the energy storage battery cover when they come into contact with it, thus better clamping the energy storage battery cover, providing a more uniform limiting force, and straightening the energy storage battery cover.

[0054] like Figure 7 , Figure 8 As shown, a first limiting roller assembly 33 and a second limiting roller assembly 57 are respectively installed in the two symmetrically distributed inclined frames of the first limiting support 32 and the second limiting support 56. When the first limiting support 32 and the second limiting support 56 come into contact with the energy storage battery cover, the arrangement of the first limiting roller assembly 33 and the second limiting roller assembly 57 can reduce the friction between the first limiting support 32 and the second limiting support 56 and the cover, making the straightening operation of the cover smoother, reducing equipment wear, and at the same time preventing the first limiting support 32 and the second limiting support 56 from causing scratches or other damage to the surface of the cover due to excessive friction, thus ensuring the quality and appearance of the cover.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
