Description

Technical Field

[0001] This application relates to the field of lithium battery manufacturing equipment technology, and in particular to a cell picking mechanism and a cell handling device. Background Technology

[0002] In the manufacturing process of lithium battery cells, after the electrodes and separators of different polarities are stacked in sequence to form a cell unit, the cell unit needs to be sent to the hot pressing position of the hot pressing device for hot pressing by the cell feeding mechanism.

[0003] Existing battery cell loading mechanisms typically use a cell handling mechanism as shown in patent document CN219729736U. This mechanism uses a clamping drive to drive grippers from one side of the battery cell unit, clamping it with multiple pairs of vertically arranged crossbars. Each crossbar is longer than the width of the battery cell unit to ensure relative fixation during clamping. When transferring the battery cell unit to the subsequent hot-pressing device, a receiving component typically extends from the center of the hot-pressing table to temporarily support the unpressed electrodes and separators. After the grippers are removed, the receiving component is lowered, and the electrodes and separators to be pressed are placed on the hot-pressing table. Then, the hot-pressing plate presses down, pressing the electrodes and separators into a single unit. It is evident that if existing grippers are used for handling, the receiving component on the hot-pressing table can only be positioned parallel to the grippers. If the battery cell is long, multiple receiving components are needed in multiple locations, increasing indentations on the surface of the hot-pressed battery cell unit and affecting the final hot-pressing effect. Utility Model Content

[0004] The purpose of this application is to provide a battery cell picking mechanism to solve the above-mentioned problems existing in the existing battery cell handling mechanism; another purpose of this application is to provide a battery cell handling device including the battery cell picking mechanism.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] In a first aspect, this application proposes a battery cell pickup mechanism, which includes a base and at least one pickup unit, wherein:

[0007] The pickup unit is mounted on the base and is configured to pick up or release a cell unit;

[0008] The pickup unit includes a drive assembly, a first mounting component, and a second mounting component. Both the first mounting component and the second mounting component are mounted on a base. The drive end of the drive assembly is connected to the first mounting component and / or the second mounting component. Both the first mounting component and the second mounting component are provided with a support portion.

[0009] The drive assembly drives the first mounting piece and the second mounting piece to move closer to each other so as to pick up the battery cell at the opposite two sides of the battery cell through the bearing parts of the first mounting piece and the second mounting piece, respectively.

[0010] The drive assembly drives the first mounting piece and the second mounting piece to move away from each other, thereby controlling the carrier portion of the first mounting piece and the second mounting piece to release the battery cell.

[0011] The battery cell pickup mechanism proposed in this application achieves automatic pickup or release of battery cell units through the cooperation of a drive assembly, a first mounting component, a second mounting component, and a carrier portion. At the same time, the carrier portions of the first and second mounting components adopt a horizontal carrier portion for the battery cell units and pick them up from the two side edges of the battery cell unit pair, which reduces the size of the pickup mechanism, reduces the space occupied by the pickup mechanism, and does not limit the number of receiving components and the installation direction on the subsequent hot pressing table, thereby improving the compatibility of the battery cell pickup mechanism and the hot pressing effect of the hot pressing device.

[0012] Optionally, a clamping assembly is also provided on the base. The clamping assembly is matched with the pickup unit and is configured to clamp and fix the battery cell unit on the support portion of the first mounting member and the second mounting member.

[0013] By setting up a clamping component, the battery cell units picked up by the first and second mounting components are clamped and fixed on the bearing parts of the two mounting components, which prevents the battery cell units from shifting during the movement of the battery cell picking mechanism and ensures the stability and reliability of picking up the battery cell units.

[0014] Optionally, the clamping assembly includes a clamping drive and a clamping element, wherein:

[0015] The clamping element is vertically mounted on the base, and the driving end of the clamping drive is connected to the clamping element. The clamping drive is configured to drive the clamping element to move up and down.

[0016] The clamping drive drives the clamping member to descend and press against the top surface of the battery cell unit, thereby clamping and fixing the battery cell unit onto the support portion of the first mounting member and the second mounting member.

[0017] By driving the clamping component to press the clamping component against the top surface of the battery cell, the battery cell is clamped and fixed on the bearing part of the first mounting component and the second mounting component, providing a clamping assembly with simple structure, low cost and good clamping effect.

[0018] Optionally, at least two pickup units are spaced apart along the height direction on the base.

[0019] By setting at least two pickup units on the base, the simultaneous pickup of at least two pickup units is achieved, which improves the working efficiency of the cell pickup mechanism.

[0020] Optionally, the drive assembly includes a first drive element, a second drive element, a first connector, and a second connector, wherein:

[0021] The first connector is reciprocally mounted on the base in a first horizontal direction. The drive end of the first drive member is connected to the first connector. The first drive member is configured to drive the first connector to reciprocate in the first horizontal direction. The first mounting member is fixedly connected to the first connector.

[0022] The second connector is mounted on the base and can reciprocate along the first horizontal direction. The driving end of the second drive is connected to the second connector. The second drive is configured to drive the second connector to reciprocate along the first horizontal direction. The second mounting piece is fixedly connected to the second connector.

[0023] By driving the corresponding first connector and second connector to reciprocate along the first horizontal direction, the first mounting component and the second mounting component move closer to each other or further away from each other, thereby picking up or releasing the battery cell unit through the bearing part, providing a stable and reliable driving component.

[0024] Optionally, the mounting position of the first mounting member on the first connector along the first horizontal direction is adjustable, and the mounting position of the second mounting member on the second connector along the first horizontal direction is adjustable.

[0025] By setting both the first and second mounting components to be adjustable in the first horizontal direction, the picking up of battery cells of different sizes and specifications in the first horizontal direction is realized, thus improving the compatibility of the battery cell picking mechanism.

[0026] Optionally, the mounting position of the support portion on the first and second mounting members along the second horizontal direction is adjustable, and the second horizontal direction is perpendicular to the first horizontal direction.

[0027] By setting the carrier to be adjustable in the installation position along the second horizontal direction, it is possible to pick up battery cells of different sizes and specifications in the second horizontal direction, further improving the compatibility of the battery cell picking mechanism.

[0028] Secondly, this application proposes a battery cell handling device, which includes a transfer mechanism and the aforementioned battery cell picking mechanism. The drive end of the transfer mechanism is connected to a base. The transfer mechanism is at least configured to drive the base to move laterally and move up and down, so as to pick up the battery cell unit to be hot-pressed by the picking unit and transport it to the hot-pressing station, or to pick up the hot-pressed battery cell unit by the picking unit and transport it to the next process.

[0029] By coordinating the transfer mechanism and the cell picking mechanism, automatic loading and unloading of the cell hot pressing device is achieved. At the same time, the small size of the cell picking mechanism does not limit the number of receiving parts and the installation direction on the subsequent hot pressing table, thus improving the compatibility of the cell picking mechanism and the hot pressing effect of the hot pressing device.

[0030] Optionally, the transfer mechanism includes a first lateral movement module, a first lateral movement plate, a second lateral movement module, a second lateral movement plate, and a lifting drive module; wherein:

[0032] The fixed end of the second transverse module is mounted on the first transverse plate, and the driving end of the second transverse module is connected to the second transverse plate. The second transverse module is configured to drive the second transverse plate to reciprocate along the first horizontal direction.

[0033] The lifting drive module is mounted on the second transverse plate. The drive end of the lifting drive module is connected to the base, and the lifting drive module is configured to drive the base to lift.

[0034] By cooperating with the first transverse module, the first transverse plate, the second transverse module, the second transverse plate, and the lifting drive module, the battery cell picking mechanism is able to transfer in the first horizontal direction, the second horizontal direction, and the height direction, providing a transfer mechanism that can realize three-axis transfer.

[0046] 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.

[0047] In the manufacturing process of lithium battery cells, after the electrodes and separators of different polarities are stacked in sequence to form a cell unit, the cell unit needs to be sent to the hot pressing position of the hot pressing device for hot pressing by the cell feeding mechanism.

[0048] Existing battery cell loading mechanisms typically use a clamping drive to clamp the battery cell unit from one side. The clamps consist of multiple pairs of vertically arranged crossbars, each longer than the width of the battery cell unit, to ensure relative fixation during clamping. When transferring the battery cell unit to the subsequent hot-pressing device, a receiving component extends from the center of the hot-pressing table to temporarily support the unpressed electrodes and separators. After the clamps are removed, the receiving component is lowered, and the electrodes and separators to be pressed are placed on the hot-pressing table. Then, the hot-pressing plate presses down, pressing the electrodes and separators together. It is evident that if existing clamps are used for handling, the receiving component on the hot-pressing table can only be positioned parallel to the clamps. If the battery cell is long, multiple receiving components are needed in multiple locations, increasing indentations on the surface of the battery cell unit after hot pressing and affecting the final hot-pressing effect.

[0049] Therefore, in a first aspect, this application provides a cell pickup mechanism, please refer to... Figure 1 and Figure 2As shown, the battery cell pickup mechanism 1 provided in this application embodiment includes a base 10 and at least one pickup unit 11. The pickup unit 11 is disposed on the base 10 and is configured to pick up or release a battery cell. The pickup unit 11 includes a drive assembly, a first mounting member 12 and a second mounting member 13. Both the first mounting member 12 and the second mounting member 13 are mounted on the base 10. The drive end of the drive assembly is connected to the first mounting member 12 and / or the second mounting member 13. Both the first mounting member 12 and the second mounting member 13 are provided with a support portion 14. The drive assembly drives the first mounting member 12 and the second mounting member 13 to move closer to each other so as to pick up the battery cell at the opposite two edges of the battery cell through the support portions 14 of the first mounting member 12 and the second mounting member 13 respectively. The drive assembly drives the first mounting member 12 and the second mounting member 13 to move away from each other so as to control the support portions of the first mounting member 12 and the second mounting member 13 to release the battery cell.

[0050] Specifically, the support portion 14 includes at least two support members 140 spaced apart. The support member 140 has an overall "L" shaped structure. The upper end of the support member 140 is mounted on the corresponding first mounting member 12 and second mounting member 13, and the lower end of the support member 140 is bent and extends inward.

[0051] As can be seen, the battery cell picking mechanism proposed in this application achieves automatic picking or releasing of battery cell units through the cooperation of the drive assembly, the first mounting member 12, the second mounting member 13 and the carrier part 14; at the same time, the carrier part 14 of the first mounting member 12 and the second mounting member 13 adopts the method of horizontally carrying the battery cell units and picking them up from the two side edges of the battery cell unit pair, which reduces the volume of the picking mechanism, reduces the space occupied by the picking mechanism, and does not limit the number of receiving parts and the installation direction on the hot pressing table in the subsequent process, thereby improving the compatibility of the battery cell picking mechanism 1 and the hot pressing effect of the hot pressing device.

[0052] Please see Figure 1 and Figure 2 As shown, in one embodiment, a clamping assembly 15 is also provided on the base 10. The clamping assembly 15 is provided in conjunction with the pickup unit. The clamping assembly 15 is configured to clamp and fix the battery cell unit on the support portion 14 of the first mounting member 12 and the second mounting member 13.

[0053] As can be seen, by setting the clamping component 15, the battery cell units picked up by the first mounting component 12 and the second mounting component 13 are clamped and fixed on the bearing part 14 of the two mounting components, which prevents the battery cell units from shifting during the movement of the battery cell picking mechanism and ensures the stability and reliability of picking up the battery cell units.

[0054] In one embodiment, the clamping assembly 15 includes a clamping drive 150 and a clamping member 151. The clamping member 151 is movably mounted on the base 10. The drive end of the clamping drive 150 is connected to the clamping member 151. The clamping drive 150 is configured to drive the clamping member 151 to move up and down. The clamping drive 150 drives the clamping member 151 to descend and press against the top surface of the battery cell to clamp and fix the battery cell to the support portion 14 of the first mounting member 12 and the second mounting member 13.

[0055] Specifically, the clamping drive 150 uses a cylinder, and the clamping component 151 uses a horizontally arranged pressure plate. A flexible layer is provided on the bottom surface of the pressure plate to avoid damaging the battery cell unit.

[0056] As can be seen, by driving the clamping drive 150 to press the clamping member 151 against the top surface of the battery cell, the battery cell is clamped and fixed on the bearing part 14 of the first mounting member 12 and the second mounting member 13, providing a clamping assembly 15 with simple structure, low cost and good clamping effect.

[0057] In one embodiment, at least two pickup units 11 are provided on the base 10 at intervals along the height direction.

[0058] It can be seen that by setting at least two pickup units 11 on the base 10, the simultaneous pickup of at least two pickup units 11 is achieved, which improves the working efficiency of the cell pickup mechanism 1.

[0059] Please see Figures 1 to 3 As shown, in one embodiment, the drive assembly includes a first drive member 16, a second drive member 17, a first connector 18, and a second connector 19. The first connector 18 can move along a first horizontal direction ( Figure 1 The first drive member 16 is reciprocally mounted on the base 10 in the X direction. The drive end of the first drive member 16 is connected to the first connector 18. The first drive member 16 is configured to drive the first connector 18 to reciprocate along the first horizontal direction. The first mounting member 12 is fixedly connected to the first connector 18. The second connector 19 is reciprocally mounted on the base 10 in the first horizontal direction. The drive end of the second drive member 17 is connected to the second connector 19. The second drive member 17 is configured to drive the second connector 19 to reciprocate along the first horizontal direction. The second mounting member 13 is fixedly connected to the second connector 19.

[0060] Specifically, there are two first connectors 18, and the two first connectors 18 are arranged along the second horizontal direction ( Figure 1The two first connectors 18 are arranged in parallel intervals in the Y direction. Both first connectors 18 are mounted on the base 10 and can reciprocate along the first horizontal direction via a sliding guide pair. There are also two second connectors 19, which are located between the two first connectors 18. The two second connectors 19 are arranged in parallel intervals in the second horizontal direction. Both second connectors 19 are mounted on the base 10 and can reciprocate along the first horizontal direction via a sliding guide pair. The sliding guide pair consists of a linear guide rail and a slider.

[0061] Specifically, both the first driving member 16 and the second driving member 17 include two cylinders. The driving rods of the two cylinders of the first driving member 16 are respectively connected to two first connecting members 18, and the driving rods of the two cylinders of the second driving member 17 are respectively connected to two second connecting members 19.

[0062] Specifically, two adjacent pickup units 11 share a set of first drive unit 16 and second drive unit 17 to simplify the overall structure.

[0063] As can be seen, by driving the corresponding first connector 18 and second connector 19 to reciprocate along the first horizontal direction through the first driving member 16 and the second driving member 17 respectively, the first mounting member 12 and the second mounting member 13 are brought closer or further away from each other, and then the battery cell unit is picked up or released by the bearing part 14, thus providing a stable and reliable driving component.

[0064] In one embodiment, the first mounting member 12 is adjustable in its mounting position along the first horizontal direction on the first connector 18, and the second mounting member 13 is adjustable in its mounting position along the first horizontal direction on the second connector 19.

[0065] Specifically, both the first connector 18 and the second connector 19 have a waist-shaped hole 180 extending along the first horizontal direction. The waist-shaped hole 180 is matched with a threaded hole on both the first mounting member 12 and the second mounting member 13. The fixing screw passes through the waist-shaped hole 180 and is locked in the corresponding threaded hole to install the first mounting member 12 on the first connector 18 and the second mounting member 13 on the second connector 19. The installation position of the first mounting member 12 and the second mounting member 13 in the corresponding waist-shaped hole 180 is adjusted to achieve the adjustment of the installation position of the first mounting member 12 and the second mounting member 13 in the first horizontal direction.

[0066] Specifically, the sidewalls of the portions of the first connector 18 and the second connector 19 where the waist-shaped holes 180 are opened are provided with scales 181. When adjusting, referring to scales 181 can ensure the accuracy of the position adjustment of the first mounting piece 12 and the second mounting piece 13.

[0067] It can be seen that by setting the first mounting component 12 and the second mounting component 13 to be adjustable in the first horizontal direction, the picking up of battery cells of different sizes and specifications in the first horizontal direction is realized, thereby improving the compatibility of the battery cell picking mechanism 1.

[0068] In one embodiment, the mounting position of the support portion 14 on the first mounting member 12 and the second mounting member 13 along the second horizontal direction is adjustable, and the second horizontal direction is perpendicular to the first horizontal direction.

[0069] Specifically, multiple threaded holes 120 are spaced apart on the inner sidewalls of the first mounting member 12 and the second mounting member 13 along the second horizontal direction. A fixing hole 121 is provided at the upper end of the bearing part 14. The fixing screw passes through the fixing hole 121 and is locked in the corresponding threaded hole 120 to fix the bearing part 14 on the corresponding mounting member. By installing the bearing part 14 in the threaded holes 120 at different positions, the installation position of the bearing part 14 on the first mounting member 12 and the second mounting member 13 along the second horizontal direction can be adjusted.

[0070] It can be seen that by setting the carrier 14 to be adjustable in the second horizontal direction, the battery cell units of different sizes and specifications in the second horizontal direction can be picked up, further improving the compatibility of the battery cell picking mechanism 1.

[0071] The cell pickup mechanism proposed in this application has the following advantages:

[0072] 1) The method of horizontally carrying the battery cell unit and picking it up from both sides of the battery cell unit pair not only has a small size and occupies little space, but also does not limit the number of receiving parts and the installation direction on the hot pressing table in the later stage, thereby improving the compatibility of the battery cell picking mechanism and the hot pressing effect of the hot pressing device.

[0073] 2) The battery cell unit is pressed and fixed by the clamping component to prevent the battery cell unit from shifting during the movement of the battery cell picking mechanism, thus ensuring the stability and reliability of picking up the battery cell unit;

[0074] 3) It can pick up multiple battery cells at the same time, which improves the working efficiency of the battery cell picking mechanism;

[0075] 4) It has good compatibility and can pick up battery cells of various specifications.

[0076] Secondly, this application also proposes a battery cell handling device, please refer to [link to relevant documentation]. Figure 1 , Figure 4 and Figure 5As shown, the battery cell handling device provided in this application embodiment includes a transfer mechanism 2 and the aforementioned battery cell picking mechanism 1. The drive end of the transfer mechanism 2 is connected to the base 10. The transfer mechanism 2 is at least configured to drive the base 10 to move laterally and move up and down, so as to pick up the battery cell unit to be hot-pressed by the picking unit 11 and transport it to the hot-pressing station, or to pick up the hot-pressed battery cell unit by the picking unit 11 and transport it to the next process.

[0077] The battery cell handling device proposed in this application achieves automatic loading and unloading of the battery cell hot pressing device through the cooperation of the transfer mechanism 2 and the battery cell picking mechanism 1. At the same time, the battery cell picking mechanism 1 is small in size and does not limit the number of receiving parts and the installation direction on the hot pressing table in the later stage, thereby improving the compatibility of the battery cell picking mechanism 1 and the hot pressing effect of the hot pressing device.

[0078] In one embodiment, the transfer mechanism 2 includes a first transverse module 20, a first transverse plate 21, a second transverse module 22, a second transverse plate 23, and a lifting drive module (not shown in the figure); wherein: the driving end of the first transverse module 20 is connected to the first transverse plate 21, and the first transverse module 20 is configured to drive the first transverse plate 21 to reciprocate along a second horizontal direction; the fixed end of the second transverse module 22 is mounted on the first transverse plate 21, and the driving end of the second transverse module 22 is connected to the second transverse plate 23, and the second transverse module 22 is configured to drive the second transverse plate 23 to reciprocate along a first horizontal direction; the lifting drive module is disposed on the second transverse plate 23, and the driving end of the lifting drive module is connected to the base 10, and the lifting drive module is configured to drive the base 10 to move up and down.

[0079] Specifically, both the first transverse module 20 and the second transverse module 22 adopt standard linear modules, preferably electric cylinders.

[0080] Specifically, the lifting drive module is a linear module consisting of a servo motor, a lead screw, and a lead screw nut.

[0081] Through the cooperation of the first transverse module 20, the first transverse plate 21, the second transverse module 22, the second transverse plate 23 and the lifting drive module, the battery cell picking mechanism 1 is able to transfer in the first horizontal direction, the second horizontal direction and the height direction, thus providing a transfer mechanism 2 that can realize three-axis transfer.

[0082] In one embodiment, the transfer mechanism 2 is also configured to drive the base 10 to rotate. The transfer mechanism 2 also includes a rotation drive module 24 and a rotating plate 25. The fixed end of the rotation drive module 24 is mounted on the second transverse plate 23, and the drive end of the rotation drive module 24 is connected to the rotating plate 25. The rotation drive module 24 is configured to drive the rotating plate 25 to rotate by a preset angle, and the fixed end of the lifting drive module 24 is mounted on the rotating plate 25.

[0083] By cooperating with the rotary drive module 24 and the rotary plate 25, the drive base 10 is rotated at a preset angle, thereby changing the orientation of the picking unit of the cell picking mechanism 1 to meet the needs of different application scenarios and improve the compatibility of the transfer mechanism 2.
