Description

Technical Field

[0001] This invention relates to the field of battery cell module production equipment technology, specifically to a pre-stacking gripper for a battery cell module production line. Background Technology

[0002] In the battery manufacturing process, multiple cells need to be packaged into cell modules, and then multiple cell modules need to be packaged into battery packs. The pre-packing gripper is a device used in the battery production line to transfer cell modules from the material picking station to the pre-pushing station.

[0003] The existing technology has several drawbacks. First, the compatibility of the pre-stacking gripper is not very high. When the specifications of a new product differ significantly in size from the previous one, the corresponding components of the pre-stacking gripper need to be replaced to adapt to the new product size, extending the production time. Second, battery cell modules are generally quite long, requiring clamping at multiple points during transport to ensure clamping stability. The current method involves setting up multiple clamping drive devices for separate clamping, which is cumbersome to debug, occupies a lot of space, and is costly. Third, depending on the process requirements, the battery water-cooling plate also needs to be transported during the transport of the battery cell module. The current method uses two different gripper devices for gripping and transporting, resulting in low integration and increased space and cost. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a pre-stacking gripper for a battery cell module production line. This gripper allows for easy adjustment of the positions of the lower and upper gripper mechanisms, thereby adjusting the gripping position to accommodate battery cell modules of different sizes. It is flexible, convenient, and has a wide range of applications.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A pre-stacking gripper for a battery cell module production line includes a fixed base and a movable support. A first guide rail is connected to one side of the fixed base. A second guide rail is fixedly connected to the first guide rail, and the second guide rail is perpendicular to the first guide rail. The second guide rail is slidably connected to the movable support. A third guide rail is connected to the movable support, and the third guide rail is parallel to the first guide rail. A plurality of lower gripper mechanisms are slidably connected to the first guide rail, and a plurality of upper gripper mechanisms are slidably connected to the third guide rail. Each lower gripper mechanism corresponds one-to-one with an upper gripper mechanism. A first clamping drive device is connected to the fixed base, and the movable end of the first clamping drive device is connected to the movable support.

[0007] The lower gripper mechanism includes a slider, a clamp, and a lower clamping plate. The slider is fixedly connected to the clamp, and both the slider and the clamp are slidably connected to the first guide rail. The lower end of the slider is fixedly connected to the lower clamping plate, and the upper end face of the lower clamping plate is provided with a clamping groove.

[0008] The upper gripper mechanism includes a second slider, a second clamping device, and an upper clamping block. The second slider is fixedly connected to the second clamping device, and both the second slider and the second clamping device are slidably connected to the third guide rail. A mounting plate is connected to the lower side of the second slider, and the upper clamping block is connected to the lower side of the mounting plate.

[0009] The upper gripper mechanism further includes a spring seat, a compression spring, and a pad block disposed between the mounting plate and the upper clamping block; the upper end face of the spring seat is provided with a slot, the bottom of the slot is provided with a vertical through mounting hole, the mounting hole is connected to a guide rod, the mounting hole supports and limits the top end of the guide rod, the lower end of the guide rod is fixedly connected to the pad block, the compression spring is disposed between the spring seat and the pad block, and the pad block is fixed to the upper clamping block.

[0010] A water-cooled plate clamping device is provided at each end of the fixed base. The water-cooled plate clamping device includes a mounting base connected to the fixed base and a vertically arranged fourth guide rail. The mounting base is connected to a lifting drive device. The movable end of the lifting drive device is connected to a lifting slide plate. The lifting slide plate is slidably connected to the fourth guide rail. A water-cooled plate lower clamp and a second clamping drive device are fixedly connected to one side of the lifting slide plate. The movable end of the second clamping drive device is connected to the water-cooled plate upper clamp.

[0011] A robotic arm connector is connected to one side of the fixed base, and the fixed base is connected to the transfer and displacement mechanism through the robotic arm connector.

[0012] The fixed base is connected to two of the first clamping drive devices, and the movable bracket is connected to two bending connecting plates, with each bending connecting plate corresponding to one of the first clamping drive devices.

[0013] The fixed base is connected to two parallel first guide rails. The two first guide rails are connected to two second guide rails and six lower gripper mechanisms. The two second guide rails divide the first guide rails into three equal parts and separate the six lower gripper mechanisms in pairs.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting several sliding lower gripper mechanisms on the first guide rail and several sliding upper gripper mechanisms on the third guide rail, the lower gripper mechanisms can slide relative to the first guide rail and the upper gripper mechanisms can slide relative to the third guide rail. When the size of the battery cell module changes, the positions of the lower and upper gripper mechanisms can be adjusted to adjust the gripping position, adapting to battery cell modules of different sizes. This avoids the inconvenience and increased cost of replacing the entire gripper mechanism, making the operation flexible and convenient, and adaptable to a wide range of applications.

[0016] 2. The first guide rail is vertically connected to the second guide rail. The first clamping drive device causes the movable bracket to slide on the second guide rail. The movable bracket drives several upper gripper mechanisms to move closer to or further away from the lower gripper mechanism, ensuring the consistency of the clamping action and the stability of clamping the battery cell module at all points. This avoids the need to set a drive device for each upper gripper mechanism, thus reducing costs.

[0017] 3. By setting water-cooled plate clamping devices at both ends of the fixed base, the two water-cooled plate clamping devices can be used to clamp the two ends of the water-cooled plate respectively, which can realize the individual clamping of the water-cooled plate, facilitate the transfer of the water-cooled plate, avoid the need to set up a separate water-cooled plate gripper, have high integration, occupy little space, and reduce costs.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely 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.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0026] like Figures 1 to 5 As shown, a pre-stacking gripper for a battery cell module production line includes a fixed base 1 and a movable support 2. A first guide rail 3 is connected to one side of the fixed base 1. A second guide rail 4 is fixedly connected to the first guide rail 3. The second guide rail 4 is perpendicular to the first guide rail 3 and is slidably connected to the movable support 2. A third guide rail 5 is connected to the movable support 2 and is parallel to the first guide rail 3. A plurality of lower gripper mechanisms 6 are slidably connected to the first guide rail 3, and a plurality of upper gripper mechanisms 7 are slidably connected to the third guide rail 5. The lower gripper mechanisms 6 and the upper gripper mechanisms 7 correspond one-to-one. A first clamping drive device 8 is connected to the fixed base 1, and the movable end of the first clamping drive device 8 is connected to the movable support 2.

[0027] In the battery manufacturing process, multiple cells need to be packaged into cell modules, and then multiple cell modules need to be packaged into battery packs. Pre-packing grippers are used to transfer cell modules in the battery production line, transferring the cell modules from the material picking station to the pre-pushing station.

[0028] By setting several sliding lower gripper mechanisms 6 on the first guide rail 3 and several sliding upper gripper mechanisms 7 on the third guide rail 5, the lower gripper mechanisms 6 can slide relative to the first guide rail 3 and the upper gripper mechanisms 7 can slide relative to the third guide rail 5. When the size of the battery cell module changes, the positions of the lower gripper mechanisms 6 and the upper gripper mechanisms 7 can be adjusted to adjust the gripping position, thereby adapting to battery cell modules of different sizes. This avoids the inconvenience and cost increase caused by replacing the entire gripper mechanism, making the operation flexible and convenient, and adaptable to a wide range of applications.

[0029] The first guide rail 3 is vertically connected to the second guide rail 4. The first clamping drive device 8 causes the movable bracket 2 to slide on the second guide rail 4. The movable bracket 2 drives several upper gripper mechanisms 7 to move closer to or further away from the lower gripper mechanism 6 as a whole, ensuring the consistency of the clamping action and the stability of clamping the battery cell module at all points. This avoids the need to set a drive device for each upper gripper mechanism 7, thus reducing costs.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the lower gripper mechanism includes a slider 9, a clamping device, and a lower clamping plate 10. The slider 9 is fixedly connected to the clamping device, and both the slider 9 and the clamping device are slidably connected to the first guide rail 3. The lower end of the slider 9 is fixedly connected to the lower clamping plate 10, and the upper end face of the lower clamping plate 10 is provided with a clamping groove. The slider 9 is used to slide and move relative to the first guide rail 3, and to install the lower clamping plate 10 at the position of the movable bracket 2, so that the lower clamping plate 10 is directly aligned with the upper gripper mechanism 7. The clamping device can grip the first guide rail 3 and is used to fix the slider 9 after adjusting its position. The clamping device can be operated manually or electrically.

[0031] In one embodiment, such as Figure 4 As shown, the upper gripper mechanism includes a second slider 11, a second clamping device 12, and an upper clamping block 13. The second slider 11 and the second clamping device 12 are fixedly connected, and both the second slider 11 and the second clamping device 12 are slidably connected to the third guide rail 5. A mounting plate 14 is connected to the lower side of the second slider 11, and the upper clamping block 13 is connected to the lower side of the mounting plate 14. The second slider 11 is used to adjust the position of the upper clamping block 13 so that the upper clamping block 13 corresponds to the lower clamping plate 10. The second clamping device 12 is used to fix the second slider 11.

[0032] In one embodiment, such as Figure 4 As shown, the upper gripper mechanism 7 also includes a spring seat 15, a compression spring 16, and a pad 18 disposed between the mounting plate 14 and the upper clamping block 13; the upper end face of the spring seat 15 is provided with a slot, the bottom of the slot is provided with a vertical through mounting hole, the mounting hole is connected to a guide rod 17, the mounting hole supports and limits the top end of the guide rod 17, the lower end of the guide rod 17 is fixedly connected to the pad 18, the compression spring 16 is disposed between the spring seat 15 and the pad 18, and the pad 18 is fixed to the upper clamping block 13.

[0033] Because the surface of the battery cell module is uneven, and the upper gripper mechanism 7 is driven by the movable bracket 2 to move uniformly, there is a height difference between each upper gripper block 13 and the battery cell module when they come into contact. Therefore, a compression spring 16 is set on the upper side of the upper gripper block 13 to achieve floating clamping. When the upper gripper block 13 moves closer to the lower clamping plate 10 and contacts the battery cell module, the upper gripper block 13 is forced to retract, causing the compression spring 16 to shorten and deform. The rebound force of the compression spring 16 causes the upper gripper block 13 to float and clamp the surface of the battery cell module. This ensures that when the upper gripper mechanism 7 moves uniformly, each upper gripper block 13 can also make close contact with the surface of the battery cell module, thus ensuring clamping stability.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, a water-cooled plate clamping device is provided at each end of the fixed base 1. The water-cooled plate clamping device includes a mounting base 19 connected to the fixed base 1 and a vertically arranged fourth guide rail 20. The mounting base 19 is connected to a lifting drive device 21. The movable end of the lifting drive device 21 is connected to a lifting slide plate 22. The lifting slide plate 22 is slidably connected to the fourth guide rail 20. A water-cooled plate lower clamp 23 and a second clamping drive device 24 are fixedly connected to one side of the lifting slide plate 22. The movable end of the second clamping drive device 24 is connected to the water-cooled plate upper clamp 25.

[0035] By setting water-cooled plate clamping devices at both ends of the fixed base 1, the two water-cooled plate clamping devices can respectively clamp the two ends of the water-cooled plate, which can realize the individual clamping of the water-cooled plate, facilitate the transfer of the water-cooled plate, avoid the need to set up a separate water-cooled plate gripper, have high integration, occupy little space, and reduce costs.

[0036] In one embodiment, a robotic arm connector 26 is connected to one side of the fixed base 1, and the fixed base 1 is connected to the transfer and displacement mechanism through the robotic arm connector 26.

[0037] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixed base 1 is connected to two first clamping drive devices 8, and the movable bracket 2 is connected to two bending connecting plates 27, each of which is connected to a corresponding first clamping drive device 8. The two first clamping drive devices 8 can ensure that the two ends of the movable bracket 2 are balanced, preventing one side from being overloaded and tilting. The bending connecting plates 27 are used to position the movable bracket 2.

[0038] In one embodiment, such as Figure 2 As shown, the fixed base 1 is connected to two parallel first guide rails 3. The two first guide rails 3 are connected to two second guide rails 4 and six lower gripper mechanisms 6. The two second guide rails 4 divide the first guide rails 3 into three equal parts and separate the six lower gripper mechanisms 6 in pairs.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
