Description

Technical Field

[0001] This application belongs to the technical field of lithium battery production equipment, and in particular relates to a cell processing device. Background Technology

[0002] When producing battery cell modules, it is necessary to pre-apply spacers or adhesive strips to the battery cells, and then stack multiple battery cells into a battery cell module through a stacking mechanism, with adjacent battery cells adhered together by spacers.

[0003] Existing battery cell processing equipment typically uses a pallet to carry multiple battery cells, which are then transported by a single conveyor line to the chip mounting and adhesive application stations. A handling mechanism removes the cells requiring chip mounting or adhesive application from the pallet, and the chip mounting and adhesive application mechanisms then apply the adhesive or chip to the removed cells before placing them back into the pallet. While this method achieves chip mounting and adhesive application, it suffers from drawbacks. If the adhesive strips or spacers are not applied accurately, the incomplete cells must be removed. Furthermore, the order of the cells in the battery cell modules is crucial. For example, cells without adhesive, cells with adhesive strips, and cells with spacers are grouped together and cyclically ordered. If one cell in a group is not properly mounted, to avoid disrupting the module's order, the entire group must be removed, or the incomplete cell must be removed and replaced with a qualified one. Therefore, existing battery cell processing equipment suffers from cumbersome operation and low production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a battery cell processing device to solve the problem of low production efficiency in existing battery cell processing devices when attaching spacers or adhesive strips to battery cells.

[0005] To achieve this objective, the present application adopts the following technical solution:

[0006] This application discloses a battery cell processing device, which includes a first conveying device, a second conveying device, a third conveying device, a rejecting device, a bonding device, and a battery cell stacking device, wherein:

[0007] The first conveying device, the second conveying device, and the third conveying device are arranged in parallel along the first horizontal direction;

[0008] The first conveying device is configured to receive the battery cell to be attached with adhesive strips and convey the battery cell to the first feeding station along the second horizontal direction; the second conveying device is configured to receive the battery cell to be attached with spacers and convey the battery cell to the second feeding station along the second horizontal direction; the third conveying device is configured to receive the battery cell that does not require adhesive strips or spacers and convey the battery cell to the third feeding station along the second horizontal direction; the first horizontal direction is perpendicular to the second horizontal direction.

[0009] A first attaching station is provided on the conveying path of the first conveying device, and a second attaching station is provided on the conveying path of the second conveying device. The attaching device is configured to attach adhesive strips to the battery cells at the first attaching station and attach spacers to the battery cells at the second attaching station.

[0010] The rejection device is located outside the first conveyor and is configured to remove defective battery cells from the first and second conveyors.

[0011] The cell stacking device is configured to pick up cells from the first feeding station, the second feeding station and the third feeding station, and stack the picked-up cells into a cell module.

[0012] The battery cell processing equipment proposed in this application has a first conveying device that transports battery cells to be attached with adhesive strips to a first attaching station, a second conveying device that transports battery cells to be attached with spacers to a second attaching station, and a third conveying device that transports battery cells that do not require adhesive strips or spacers to a third feeding station. The attaching device attaches adhesive strips to the battery cells at the first attaching station and attaches spacers to the battery cells at the second attaching station. The battery cell stacking device picks up the battery cells at the first, second, and third feeding stations and stacks them into battery cell modules, thus realizing automatic battery cell stacking. At the same time, since it is not necessary to remove or put back the battery cells at the first and second attaching stations, the process of attaching adhesive strips and spacers is simplified, improving the battery cell processing efficiency. Moreover, the rejection device can promptly remove unqualified battery cells from the first and second conveying devices, preventing unqualified battery cells from flowing into the stacking process and ensuring the processing quality of the battery cell modules.

[0013] Optionally, the first, second, and third conveying devices each include a conveyor frame, a conveyor motor, a conveyor chain, and several battery cell fixtures, wherein:

[0014] The conveyor chain is rotatably mounted on the conveyor frame, and the drive end of the conveyor motor is connected to the conveyor chain. The conveyor motor is configured to drive the conveyor chain to rotate.

[0015] Several battery cell fixtures are installed at intervals on the conveyor chain. Each battery cell fixture is configured to carry and position at least one battery cell. The conveyor motor drives the conveyor chain to rotate, thereby causing the several battery cell fixtures to move along the conveyor path of the conveyor chain.

[0016] The second conveying device is disposed between the first conveying device and the third conveying device. The two ends of the first conveying device along the second horizontal direction are aligned with the two ends of the third conveying device along the second horizontal direction in the first horizontal direction. The end of the second conveying device on which the conveying motor is mounted protrudes from the first conveying device and the third conveying device along the second horizontal direction.

[0017] By configuring the first, second, and third conveying devices, the conveyor motor drives the conveyor chain to rotate, thereby moving several battery cell fixtures mounted on the conveyor chain. This allows the battery cells carried and clamped on the fixtures to be conveyed to the next process. This not only ensures stability, durability, high efficiency, and precision, but also provides good flexibility and safety. Furthermore, aligning the two ends of the first and third conveying devices in the first horizontal direction, and having the end of the second conveying device equipped with the conveyor motor protrude beyond the first and second conveying devices in the second horizontal direction, reduces the distance between adjacent conveying devices, saving floor space.

[0018] Optionally, the battery cell fixture includes a first limiting block and a second limiting block spaced apart on the conveyor chain. Both the first and second limiting blocks are provided with limiting grooves. The two ends of the battery cell along the second horizontal direction are respectively inserted into the limiting grooves on the first and second limiting blocks, so that the battery cell is suspended on the battery cell fixture.

[0019] Clamping components are provided on the sides of both the first and second attaching stations. These clamping components are configured to clamp and position the battery cells on the battery cell fixtures at the first and second attaching stations. Each clamping component includes a moving module, a clamping drive unit, a carrier unit, and grippers, wherein:

[0020] The drive end of the mobile module is connected to the carrier. The mobile module is configured to drive the carrier to insert into or move away from the gap between the cell fixture and the suspended cell in a first horizontal direction. The mobile module is also configured to drive the carrier to rise to lift the cell or fall to place the cell on the cell fixture.

[0021] The grippers and clamping drive are mounted on the carrier, and the clamping drive is configured to drive the grippers to clamp or release the two ends of the battery cell along the second horizontal direction.

[0022] By cooperating with the first and second limiting blocks, the battery cell is suspended and limited on the battery cell fixture. By setting up the clamping component, the battery cells at the first and second attaching stations are clamped and positioned when the adhesive strip is applied to the battery cell at the first attaching station and when the spacer is applied to the battery cell at the second attaching station. This prevents the battery cell from tilting due to force when the adhesive strip or spacer is applied, which would affect the attaching quality of the adhesive strip or spacer.

[0023] Optionally, the cell stacking device includes a support platform, a pick-up assembly, and a stacking assembly, wherein:

[0024] The support platform extends along the first horizontal direction, and the first feeding station, the second feeding station and the third feeding station are aligned along the first horizontal direction. The picking end of the picking component is configured to slide horizontally along the first horizontal direction to the first feeding station, the second feeding station and the third feeding station to pick up the battery cell and send it to the support platform. The stacking component is configured to stack the individual battery cells on the support platform into a battery cell module.

[0025] or,

[0026] The support platform extends along the second horizontal direction. The pickup end of the pickup component is configured to rotate around the mounting base of the pickup component. The first feeding station, the second feeding station, the third feeding station and the support platform are respectively located on the rotation path of the pickup end of the pickup component. The pickup end of the pickup component is configured to rotate to the first feeding station, the second feeding station and the third feeding station to pick up the battery cell and send it to the support platform. The stacking component is configured to stack the individual battery cells on the support platform into a battery cell module.

[0027] By setting the support platform to extend along a first horizontal direction, the picking component slides along the first horizontal direction to deliver the battery cells from the three feeding stations to the support platform, and the stacking component then stacks the individual battery cells on the support platform into a battery cell module. The movement path of the battery cells is a straight line, providing a battery cell stacking device with a simple structure and easy implementation. By setting the support platform to extend along a second horizontal direction, the picking component rotates around the center of the mounting seat to deliver the battery cells from the three feeding stations to the support platform, and the stacking component then stacks the individual battery cells on the support platform into a battery cell module. The movement path of the battery cells is a circular motion, providing a battery cell stacking device with high working efficiency and high space utilization.

[0028] Optionally, the bonding device includes a bonding mechanism, with a first bonding station and a second bonding station aligned in a first horizontal direction. The bonding mechanism is disposed on the side of the first bonding station or the second bonding station and is configured to bond adhesive strips to the battery cell at the first bonding station and to bond spacers to the battery cell at the second bonding station.

[0029] By configuring the bonding device to include a bonding mechanism, which connects to a first conveying device and a second conveying device, to bond adhesive strips to the battery cells at the first bonding station or to bond spacers to the battery cells at the second bonding station, a bonding device with a simple structure is provided.

[0030] Optionally, the bonding device includes two bonding mechanisms. The first bonding mechanism corresponds to the first conveying device and is configured to bond adhesive strips to the battery cells at the first bonding station. The second bonding mechanism corresponds to the second conveying device and is configured to bond spacers to the battery cells at the second bonding station.

[0031] By setting the bonding device to include two bonding mechanisms, the first bonding mechanism bonds the adhesive strip to the battery cell at the first bonding station, and the second bonding mechanism bonds the spacer to the battery cell at the second bonding station. This achieves that the adhesive strip bonding process and the spacer bonding process do not interfere with each other, improves the bonding efficiency of the adhesive strip and spacer, and meets the needs of fast-paced production.

[0032] Optionally, the attachment mechanism includes a first transport assembly, a transfer assembly, a film-peeling assembly, a transfer assembly, and a second transport assembly, wherein:

[0033] The first handling component is configured to pick up the adhesive strip or spacer to be attached and move the picked-up adhesive strip or spacer to the transfer component;

[0034] The transfer assembly includes a base, a rotary drive assembly, a rotary support, and at least three adsorption components. The rotary support is rotatably mounted on the base, and the rotary drive assembly is mounted on the base with its drive end connected to the rotary support. The adsorption components are evenly spaced along the circumference of the rotary support. The rotary drive assembly is configured to drive the rotary support to rotate around its own central axis to rotate each adsorption component. A detection station, a first film-tearing station, and a loading station are sequentially arranged along the rotation path of each adsorption component. When an adsorption component rotates to the detection station, it is configured to receive adhesive strips or spacers transported by the first conveying assembly. When an adsorption component rotates to the first film-tearing station, it is configured to cooperate with the film-tearing assembly to tear off the first release paper on the first surface of the adhesive strip or spacer. When an adsorption component rotates to the loading station, it is configured to release the adhesive strip or spacer with the first release paper to the transfer assembly. When the first adsorption component is at the detection station, the second adsorption component is at the first film-tearing station, and the third adsorption component is at the loading station.

[0035] The transfer component is configured to pick up the adhesive strip or spacer on the adsorption component at the loading station and rotate the picked-up adhesive strip or spacer by a preset angle so that the second release paper on the second surface of the adhesive strip or spacer faces the second transport component.

[0036] The second handling assembly is configured to pick up the adhesive strip on the adapter assembly and attach it to the battery cell at the first attachment station, or to pick up the spacer on the adapter assembly and attach it to the battery cell at the second attachment station.

[0037] By cooperating with the first handling component, the transfer component, the switching component, and the second handling component, the first release paper of the adhesive strip or spacer is automatically removed and the adhesive strip or spacer is automatically attached to the battery cell at the first or second attachment station, resulting in high work efficiency. Moreover, by cooperating with the rotary drive component, the rotary bracket, and at least three adsorption components, an adsorption component is present at the detection station, the first film-removing station, and the loading station at the same time. The adsorption components at the three stations can simultaneously perform the receiving and film-removing work of the adhesive strip or spacer, thereby speeding up the work pace and improving work efficiency. In addition, the overall structure is compact and occupies little space.

[0038] Optionally, a second film-peeling station is provided on the conveying path of the first conveying device, located after the first attaching station. The first conveying device is also configured to convey the battery cell after the adhesive strip is attached to the second film-peeling station.

[0039] The second conveying device has a third film-peeling station located after the second attaching station on its conveying path. The second conveying device is also configured to convey the battery cells after attaching the spacers to the third film-peeling station.

[0040] The second and third film-tearing stations are aligned in the first horizontal direction. The material removal device is located on the side of the second or third film-tearing station. The material removal device is also configured to remove the second release paper of the adhesive strip on the battery cell at the second film-tearing station and the second release paper of the spacer on the battery cell at the third film-tearing station.

[0041] By setting a second film-tearing station on the conveying path of the first conveying device and a third film-tearing station on the conveying path of the second conveying device, and by connecting the rejecting device to the first and second conveying devices, the second release paper on the adhesive strip of the battery cell at the second film-tearing station and the second release paper on the spacer of the battery cell at the third film-tearing station are automatically removed. The degree of automation is high and the processing efficiency of the battery cells is improved.

[0042] Optionally, the rejection device is also configured to inspect the battery cells at the second and third film-tearing stations to determine whether the adhesive strips on the battery cells at the second film-tearing station are properly attached and whether the spacers on the battery cells at the third film-tearing station are properly attached, and to remove battery cells with unqualified adhesive strips and spacers based on the inspection results.

[0043] The automatic detection of the bonding quality of the battery cells at the second and third film-peeling stations by the rejection device, and the timely removal of battery cells with unqualified adhesive strips and spacers, realizes the automatic rejection of battery cells with unqualified adhesive strips and spacers, thus improving production efficiency.

[0044] Optionally, the cell processing equipment includes a feeding device, which comprises a feeding conveyor line, an OVC detection mechanism, and a handling mechanism, wherein:

[0045] The feeding conveyor line has a detection station and a feeding station set up sequentially along its conveying path. The feeding conveyor line is configured to receive battery cells and transport the received battery cells sequentially to the detection station and the feeding station.

[0046] The OVC testing unit is set up at the testing station and is configured to perform OVC testing on the battery cells at the testing station.

[0047] The conveying mechanism is configured to pick up the battery cells at the loading station and sequentially transport the picked-up battery cells to the first conveying device, the second conveying device, and the third conveying device.

[0064] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] Existing battery cell processing equipment typically uses a pallet to carry multiple battery cells, which are then transported by a single conveyor line to the chip mounting and adhesive application stations. A handling mechanism removes the cells requiring chip mounting or adhesive application from the pallet, and the chip mounting and adhesive application mechanisms then apply the adhesive or chip to the removed cells before placing them back into the pallet. While this method achieves chip mounting and adhesive application, it suffers from drawbacks. If the adhesive strips or spacers are not applied accurately, the incomplete cells must be removed. Furthermore, the order of the cells in the battery cell modules is crucial. For example, cells without adhesive, cells with adhesive strips, and cells with spacers are grouped together and cyclically ordered. If one cell in a group is not properly mounted, to avoid disrupting the module's order, the entire group must be removed, or the incomplete cell must be removed and replaced with a qualified one. Therefore, existing battery cell processing equipment suffers from cumbersome operation and low production efficiency.

[0066] Therefore, this application proposes a cell processing device, please refer to [link to relevant documentation]. Figure 1 and Figure 2 As shown, the battery cell processing equipment proposed in this application includes a first conveying device 10, a second conveying device 20, a third conveying device 30, a rejecting device 40, an attaching device 50, and a battery cell stacking device 60, wherein: the first conveying device 10, the second conveying device 20, and the third conveying device 30 are along a first horizontal direction ( Figure 1The first conveying device 10 is configured to receive the battery cell 70 to be attached with adhesive strips and to move the battery cell 70 along the second horizontal direction (X direction). Figure 1 The first conveyor 10 is configured to receive the battery cell 70 to be attached with a spacer and convey the battery cell 70 along the second horizontal direction to the second feeding station. The second conveyor 20 is configured to receive the battery cell 70 that does not require the attachment of adhesive strips or spacers and convey the battery cell 70 along the second horizontal direction to the third feeding station. The first horizontal direction is perpendicular to the second horizontal direction. The first attachment station is set on the conveying path of the first conveyor 10, and the second attachment station is set on the conveying path of the second conveyor 20. The attachment station is configured to attach adhesive strips to the battery cells 70 at the first attachment station and attach spacers to the battery cells 70 at the second attachment station; the rejection device 40 is located outside the first conveying device 10 and is configured to remove unqualified battery cells 70 from the first conveying device 10 and the second conveying device 20; the battery cell stacking device 60 is configured to pick up the battery cells 70 from the first feeding station, the second feeding station and the third feeding station, and stack the picked-up battery cells 70 into a battery cell module.

[0067] The battery cell processing equipment proposed in this application has a first conveying device 10 that conveys battery cells 70 to be attached with adhesive strips to a first attaching station, a second conveying device 20 that conveys battery cells 70 to be attached with spacers to a second attaching station, and a third conveying device 30 that conveys battery cells 70 that do not require adhesive strips or spacers to a third feeding station. An attaching device 50 applies adhesive strips to the battery cells 70 at the first attaching station and applies spacers to the battery cells 70 at the second attaching station. A battery cell stacking device 60 picks up cells from the first feeding station, the second feeding station, and the third feeding station. The three feeding stations automatically stack the battery cells 70 into battery cell modules. This simplifies the process by eliminating the need to remove or replace the battery cells 70 at the first and second attaching stations, thus improving processing efficiency. Furthermore, the rejection device 40 promptly removes defective battery cells 70 from the first and second conveying devices 10 and 20, preventing them from flowing into the stacking process and ensuring the quality of the battery cell modules. After the rejection device removes the defective battery cells 70, subsequent qualified battery cells 70 automatically fill the gap at the feeding station, without affecting the normal feeding cycle of the battery cell stacking device 60. This eliminates the need for an additional replenishment device, reducing production costs and increasing efficiency.

[0068] Please see Figures 1 to 4As shown, in one embodiment, the first conveying device 10, the second conveying device 20, and the third conveying device 30 each include a conveying frame 11, a conveying motor 12, a conveying chain 13, and a plurality of battery cell fixtures 14.

A plurality of battery cell fixtures 14 are spaced apart on the conveying chain 13. Each battery cell fixture 14 is configured to carry and position at least one battery cell 70. The conveying motor 12 drives the conveying chain 13 to rotate, thereby causing the plurality of battery cell fixtures 14 to move along the conveying path of the conveying chain 13. The second conveying device 20 is disposed between the first conveying device 10 and the third conveying device 30. The two ends of the first conveying device 10 along the second horizontal direction are aligned with the two ends of the third conveying device 30 along the second horizontal direction in the first horizontal direction. One end of the second conveying device 20 on which the conveying motor 12 is mounted protrudes from the first conveying device 10 and the third conveying device 30 along the second horizontal direction.

[0069] Specifically, multiple connecting plates 15 are mounted on the mounting surface of the conveyor chain 13. The battery cell fixture 14 is detachably and fixedly mounted on the corresponding connecting plate 15. Part of the connecting plate 15 is fixed to the conveyor chain 13, while the remaining part is not connected to the conveyor chain 13, to avoid the connecting plate 15 affecting the normal rotation of the conveyor chain 13 at both ends of the conveyor frame 11 in the second horizontal direction.

[0070] As can be seen, by setting up the first conveying device 10, the second conveying device 20 and the third conveying device 30, the conveying motor 12 drives the conveying chain 13 to rotate, thereby moving a number of battery cell fixtures 14 mounted on the conveying chain 13, and then conveying the battery cells 70 carried and clamped on the battery cell fixtures 14 to the next process. This is not only stable, durable, efficient and precise, but also flexible and safe. At the same time, aligning the two ends of the first conveying device 10 and the third conveying device 30 in the first horizontal direction, and having one end of the second conveying device 20 with the conveying motor 12 protrude from the first conveying device 10 and the third conveying device 30 in the second horizontal direction, can reduce the distance between two adjacent conveying devices and save space.

Both the first limiting block 140 and the second limiting block 141 are provided with limiting grooves 142. The two ends of the battery cell 70 along the second horizontal direction are respectively inserted into the limiting grooves 142 on the first limiting block 140 and the second limiting block 141, so that the battery cell 70 is suspended on the battery cell fixture 14. Clamping components 16 are provided on the sides of both the first and second attaching stations. The clamping components 16 are configured to clamp and position the battery cell 70 on the battery cell fixture 14 at the first and second attaching stations. Component 16 includes a moving module (not shown), a clamping drive 160, a carrier 161, and a gripper 162, wherein: the driving end of the moving module is connected to the carrier 161, and the moving module is configured to drive the carrier 161 to insert into or move away from the gap between the cell fixture 14 and the suspended cell 70 along a first horizontal direction; the moving module is also configured to drive the carrier 161 to rise to lift the cell 70 or to fall to place the cell 70 on the cell fixture 13; the gripper 162 and the clamping drive 160 are disposed on the carrier 161, and the clamping drive 160 is configured to drive the gripper 162 to clamp or release the two ends of the cell 70 along a second horizontal direction.

[0072] Specifically, the gripper drive 160 can be a single double-headed cylinder, with the two piston rods of the double-headed cylinder connected to the two gripping parts of the gripper 162 respectively; the gripper drive 160 can also be two single-headed cylinders, with each single-headed cylinder corresponding to one gripping part of the gripper 162, and the piston rod of the single-headed cylinder connected to the corresponding gripping part of the gripper 162.

[0073] As can be seen, through the cooperation of the first limiting block 140 and the second limiting block 141, the battery cell 70 is suspended and limited on the battery cell fixture 14. By setting the clamping component 16, the battery cell 70 at the first and second attaching stations is clamped and positioned when the adhesive strip is applied to the battery cell 70 at the first attaching station and when the spacer is applied to the battery cell 70 at the second attaching station, so as to avoid the battery cell 70 tilting due to force when the adhesive strip or spacer is applied, which would affect the attaching quality of the adhesive strip or spacer.

[0074] Please see Figure 1 and Figure 2 As shown, in one embodiment, the cell stacking device 60 includes a support platform 61, a pickup component 62, and a stacking component 63, wherein: the support platform 61 extends along a first horizontal direction, the first feeding station, the second feeding station, and the third feeding station are aligned along the first horizontal direction, the pickup end of the pickup component 62 is configured to slide horizontally along the first horizontal direction to the first feeding station, the second feeding station, and the third feeding station to pick up the cells and send them to the support platform 61, and the stacking component 63 is configured to stack the individual cells 70 on the support platform 61 into a cell module.

[0075] As can be seen, by setting the carrier platform 61 to extend along the first horizontal direction, the picking component 62 slides along the first horizontal direction to deliver the battery cells 70 at the three feeding stations to the carrier platform 61, and the stacking component 63 then stacks the individual battery cells 70 on the carrier platform 61 into a battery cell module. During the stacking process, the movement path of the battery cells 70 is a straight line, which provides a battery cell stacking device 60 with a simple structure and easy implementation.

[0076] In one embodiment, the cell stacking device 60 includes a support platform 61, a pickup component 62, and a stacking component 63. The support platform 61 extends along a second horizontal direction. The pickup end of the pickup component 62 is configured to rotate around the mounting base of the pickup component 62. The first feeding station, the second feeding station, the third feeding station, and the support platform 61 are respectively located on the rotation path of the pickup end of the pickup component 62. The pickup end of the pickup component 62 is configured to rotate to the first feeding station, the second feeding station, and the third feeding station to pick up the cells 70 and deliver them to the support platform 61. The stacking component 63 is configured to stack the individual cells 70 on the support platform 61 into a cell module.

[0077] As can be seen, by setting the support platform 61 to extend along the second horizontal direction, the picking component 62 rotates around the center of the mounting seat to deliver the battery cells 70 at the three feeding stations to the support platform 61, and the stacking component 63 then stacks the individual battery cells 70 on the support platform 61 into a battery cell module. The movement path of the battery cells 70 is a circular motion, which provides a battery cell stacking device 60 with high working efficiency and high space utilization.

[0078] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the attaching device 50 includes an attaching mechanism, with a first attaching station and a second attaching station aligned in a first horizontal direction. The attaching mechanism is disposed on the side of the first attaching station or the second attaching station and is configured to attach an adhesive strip to the battery cell at the first attaching station and attach a spacer to the battery cell at the second attaching station.

[0079] As can be seen, by configuring the attaching device 50 to include an attaching mechanism, which connects to the first conveying device 10 and the second conveying device 20, to attach adhesive strips to the battery cell 70 at the first attaching station or attach spacers to the battery cell 70 at the second attaching station, a simple attaching device 50 is provided.

[0080] In one embodiment, the attaching device 50 includes two attaching mechanisms. The first attaching mechanism corresponds to the first conveying device 10 and is configured to attach adhesive strips to the battery cell 70 at the first attaching station. The second attaching mechanism corresponds to the second conveying device 20 and is configured to attach spacers to the battery cell 70 at the second attaching station.

[0081] It can be seen that by setting the attaching device 50 to include two attaching mechanisms, the first attaching mechanism attaches the adhesive strip to the battery cell 70 at the first attaching station, and the second attaching mechanism attaches the spacer to the battery cell 70 at the second attaching station, the adhesive strip attaching process and the spacer attaching process do not interfere with each other, thereby improving the attaching efficiency of the adhesive strip and spacer and meeting the needs of fast-paced production.

[0082] In one embodiment, the attachment mechanism includes a first transport assembly 51, a transfer assembly 52, a film-peeling assembly 53, a transfer assembly (not shown), and a second transport assembly 54. The first transport assembly 51 is configured to pick up the adhesive strip or spacer to be attached and move the picked-up adhesive strip or spacer to the transfer assembly 52. ​​The transfer assembly 52 includes a base 520, a rotation drive assembly 521, a rotation bracket 522, and at least three suction members 523. The rotation bracket 522 is rotatably mounted on the base 520. A drive assembly 521 is mounted on a base 520. The drive end of the rotary drive assembly 521 is connected to a rotary support 522. Each adsorption element 523 is evenly spaced along the circumference of the rotary support 522. The rotary drive assembly 521 is configured to drive the rotary support 522 to rotate around its own central axis, thereby rotating each adsorption element 523. A detection station 55, a first film-tearing station 56, and a loading station 57 are sequentially arranged along the rotation path of each adsorption element 523. When the adsorption element 523 rotates to the detection station 55... The adsorption member 523 is configured to receive the adhesive strip or spacer conveyed by the first conveying assembly 51; when the adsorption member 523 rotates to the first film-tearing station 56, the adsorption member 523 is configured to cooperate with the film-tearing assembly 53 to tear off the first release paper on the first surface of the adhesive strip or spacer; when the adsorption member 523 rotates to the loading station 57, the adsorption member 523 is configured to release the adhesive strip or spacer with the first release paper to the transfer assembly; when the first adsorption member 523 is located at the detection station 55, the second adsorption member 523 is located at the first film-tearing station 56. At the film station 56, the third adsorption element 523 is located at the loading station 57; the transfer assembly is configured to pick up the adhesive strip or spacer on the adsorption element 523 at the loading station 57 and rotate the picked-up adhesive strip or spacer by a preset angle so that the second release paper on the second surface of the adhesive strip or spacer faces the second transport assembly 54; the second transport assembly 54 is configured to pick up the adhesive strip on the transfer assembly and attach it to the battery cell 70 at the first attachment station or pick up the spacer on the transfer assembly and attach it to the battery cell 70 at the second attachment station.

[0083] The general working process of the above-mentioned attachment mechanism is as follows: In the initial state, there is an adsorption component 34 at each of the detection station 55, the first film peeling station 56, and the material feeding station 57.

[0084] S1, the first conveying component 51 picks up the adhesive strip or spacer to be attached and moves the picked-up adhesive strip or spacer to the inspection station 55;

[0085] S2, the adsorption component 523 located at the detection station 55 adsorbs the adhesive strip or spacer to be attached at the detection station 55.

[0086] S3, the rotary drive assembly 521 drives the rotary bracket 522 to rotate at a preset angle, so that the adsorption component 523 adsorbing the adhesive strip or spacer to be attached rotates to the first film-peeling station 56.

[0087] S4, the adsorption element 523, in conjunction with the film-tearing assembly 53, peels off the first release paper on the first surface of the adhesive strip or spacer, exposing the adhesive strip or spacer on its first sticky surface;

[0088] S5, the rotary drive assembly 521 drives the rotary bracket 522 to rotate by a preset angle again, so that the adsorption component 523 adsorbing the adhesive strip or spacer to be attached rotates to the loading station 57.

[0089] S6, the transfer component picks up the adhesive strip or spacer on the adsorption component 523 at the feeding station 57 and rotates the picked-up adhesive strip or spacer by a preset angle so that the second release paper on the second surface of the adhesive strip or spacer faces the second conveying component 54.

[0090] S7, the second conveying component 54 picks up the adhesive strip on the adapter component and attaches it to the battery cell 70 at the first attachment station, or picks up the spacer on the adapter component and attaches it to the battery cell 70 at the second attachment station.

[0091] Specifically, both the first transport component 51 and the second transport component 54 include a driving component and an adsorption component 523. The driving end of the driving component is connected to the adsorption component 523. The driving component is a transfer module consisting of a horizontal movement module and a lifting module. The driving component drives the adsorption component 523 to move horizontally and lift vertically.

[0092] Specifically, the film-tearing assembly 53 includes a film-tearing drive 530 and a film-tearing gripper 531. The drive end of the film-tearing drive 530 is connected to the film-tearing gripper 531. The film-tearing drive 530 is configured to drive the film-tearing gripper 531 to move laterally. The film-tearing gripper 531 is configured to clamp or release the tearing end of the first release paper on the first surface of the adhesive strip or spacer at the first film-tearing station 56. After the film-tearing gripper 531 clamps the tearing end of the first release paper on the first surface of the adhesive strip or spacer at the first film-tearing station 56, the film-tearing drive 530 drives the film-tearing gripper 531 to move laterally to tear off the first release paper on the first surface of the adhesive strip or spacer.

[0093] As can be seen, through the cooperation of the first conveying component 51, the transfer component 52, the transfer component and the second conveying component 54, the first release paper of the adhesive strip or spacer is automatically removed and the adhesive strip or spacer is automatically attached to the battery cell 70 at the first attachment station or the second attachment station, which is highly efficient. Moreover, through the cooperation of the rotary drive component 521, the rotary bracket 522 and at least three adsorption components 523, an adsorption component 523 is present at the detection station, the first film-tearing station and the loading station at the same time. The adsorption components 523 at the three stations can simultaneously perform the receiving and film-tearing work of the adhesive strip or spacer, thereby speeding up the work rhythm and improving work efficiency. In addition, the overall structure is compact and occupies little space.

[0094] In one embodiment, the attachment mechanism includes four adsorption elements 523, which are evenly arranged circumferentially on the rotating support 522. An idle station 58 is also provided on the rotation path of the adsorption elements 523, located between the detection station 55 and the loading station 57. The detection station 55, the first film-tearing station 56, the loading station 57, and the idle station 58 are evenly arranged circumferentially on the rotation path of the adsorption elements 523. When one of the adsorption elements 523 is located at the detection station 55, there is one adsorption element 523 at each of the first film-tearing station 56, the loading station 57, and the idle station 58.

[0095] As can be seen, by setting four stations along the rotation path of the adsorption component 523, each of the four adsorption components 523 has an adsorption assembly 523 present at the same time: the detection station 55, the first film-tearing station 56, the feeding station 57, and the idle station 58. Except for the adsorption component 523 at the idle station 58, the remaining three adsorption components 523 can simultaneously perform the receiving, film-tearing, and release of the three adhesive strips or spacers at their respective processing stations, thus accelerating the work pace and improving work efficiency. Furthermore, by setting the idle station 58, when an adsorption component 523 at another station fails, the adsorption component 523 at the idle station can be adjusted to replace the damaged adsorption assembly 523, demonstrating high fault tolerance.

[0096] Please see Figure 1 and Figure 2As shown, in one embodiment, the first conveying device 10 has a second film-peeling station located after the first attaching station on its conveying path. The first conveying device 10 is also configured to convey the battery cell with the adhesive strip attached to it to the second film-peeling station. The second conveying device 20 has a third film-peeling station located after the second attaching station on its conveying path. The second conveying device 20 is also configured to convey the battery cell with the spacer attached to it to the third film-peeling station. The second film-peeling station and the third film-peeling station are aligned in a first horizontal direction. The material-removing device 40 is located on the side of the second film-peeling station or the third film-peeling station. The material-removing device 40 is also configured to remove the second release paper of the adhesive strip on the battery cell 70 at the second film-peeling station and the second release paper of the spacer on the battery cell 40 at the third film-peeling station.

[0097] As can be seen, by setting a second film-tearing station on the conveying path of the first conveying device 10 and a third film-tearing station on the conveying path of the second conveying device 20, and by connecting the material-removing device 40 to the first conveying device 10 and the second conveying device 20, the second release paper of the adhesive strip on the battery cell 70 at the second film-tearing station and the second release paper of the spacer on the battery cell 70 at the third film-tearing station are automatically removed. The degree of automation is high and the processing efficiency of the battery cells is improved.

[0098] In one implementation, the rejection device 40 is also configured to inspect the battery cells 70 at the second and third film-tearing stations to determine whether the adhesive strip on the battery cells 70 at the second film-tearing station is properly attached and whether the spacer on the battery cells 70 at the third film-tearing station is properly attached, and to remove the battery cells 70 with unqualified adhesive strip and spacer attachment based on the inspection results.

[0099] It can be seen that by automatically detecting the bonding quality of the battery cells 70 at the second and third film-peeling stations through the rejection device 40, and promptly removing the battery cells 70 with unqualified adhesive strips and spacers, the automatic rejection of battery cells with unqualified adhesive strips and spacers is achieved, thereby improving production efficiency.

By setting up the OVC detection mechanism 82 on the feeding conveyor line 81, the battery cell 70 is automatically detected in advance to remove the battery cell that fails the OVC test and ensure the processing quality of the battery cell module. By setting up the conveying mechanism 83, the battery cell 70 at the feeding station of the feeding conveyor line 82 is automatically conveyed to the first conveying device 10, the second conveying device 20 and the third conveying device 30.
