Description

Technical Field

[0001] This invention relates to the field of battery cell delivery, and more particularly to a multi-station feeding device. Background Technology

[0002] During the production process, the battery cells need to be charged, and then tested after charging.

[0003] Throughout the entire process, the battery cells are charged in batches. In the current production process, the battery cells are placed in a fixture in batches, and the fixture constrains the position between each battery cell, which simplifies the positioning steps for subsequent charging and testing.

[0004] Current feeding equipment uses single-station batch feeding, which places multiple unidirectional battery cells (with tabs on the cells and a specific arrangement direction) directly into the fixture.

[0005] As we all know, single-station designs are inefficient. To improve efficiency, dual-station designs are the most effective and common approach. However, the current fixtures position the battery cells by using a clamping function. The clamping components that perform this function all face the same direction. Considering that the mechanism for opening the clamping components is integrated into the entire transfer mechanism, adding a station in the conventional way would make the mechanism's reciprocating path more complex. Obviously, this is not suitable for the current feeding method.

[0006] To meet the needs of multi-station operation, the current approach involves redesigning the feeding device by replacing the fixtures. The change in fixtures primarily involves altering the layout; the new fixtures are arranged in a single row with symmetrical spacing (e.g., ...). Figure 1 As shown in the figure, that is, the orientation of the upper and lower clamping parts is opposite. Therefore, the existing feeding device cannot feed the new fixture in a dual-station manner. Summary of the Invention

[0045] Please see Figure 1-20 As shown, a multi-station feeding device includes, in sequence, a flipping mechanism 1, a flattening mechanism 2, and a row spacing adjustment mechanism 3.

[0046] The flipping mechanism 1 has an output end with a positioning effect and includes a first linear moving mechanism 1000 suspended at the output end. The output end of the first linear moving mechanism 1000 is provided with a rotating mechanism 10 and a second clamping part 11, and the output end of the rotating mechanism 10 is provided with a first clamping part 12.

[0047] The first clamping part 12 and the second clamping part 11 are designed as a dual-station unit. The rotating mechanism 10 can change the position of the battery cell and change the orientation of the tabs on the battery cell 4. In this regard, after the battery cell 4 is flipped and flattened by the flipping mechanism 1, the tabs on the battery cell 4 are facing away from the clamping component. Therefore, the tabs will not be clamped by the clamping component.

[0048] The flattening mechanism 2 includes a first part 20, a pressure plate 21, and a lifting mechanism 23. The middle area of ​​the first part 20 is an open structure. Multiple pressure plates 21 are provided. The pressure plates 21 are located in the open structure. The head of the pressure plate 21 has a pressing part 21a extending toward the surface of the first part 20. The surface of the first part 20 is provided with multiple first positioning grooves 20a corresponding to the pressing part 21a. The output end of the lifting mechanism 23 is connected to the pressure plate 21.

[0049] The middle area of ​​the first part 20 is hollowed out, so that the multiple pressure plates 21 set in the open structure can face all directions on the surface of the first part 20. The head of the first part 20 is provided with a pressing part 21a. Under the action of the telescopic mechanism, the pressing part 21a can fall into the first positioning groove 20a in different directions and flatten the electrode tab in the first positioning groove 20a. Thus, the pressing of the electrode tab is realized on the symmetrically arranged battery cell 4.

[0050] The row spacing adjustment mechanism 3 includes a second part 31 that carries the battery cell clamp 5. The row spacing adjustment mechanism 3 includes a worktable 32 and a third movable plate 34 and a positioning plate 33 disposed on the worktable 32. The third movable plate 34 is disposed on the positioning plate 33. The third movable plate 34 has an end that extends to the surface of the worktable 32. The end is slidably connected to the worktable 32. A positioning protrusion 33a provided on the positioning plate 33 and the side of the third movable plate 34 form a positioning area for constraining the battery cell 4. In the positioning area, there are multiple movable positioning components 36 that divide the positioning area into multiple slots.

[0051] The positioning device is pre-set with multiple positioning slots for the battery cells 4. The positioning protrusion 33a and the third movable plate 34 apply pressure to the side of the battery cell 4 along the length direction, so that the position of the battery cell 4 is adjusted to a certain extent in the predetermined position and direction. The positioning component 36 applies pressure to the side of the battery cell 4 along the width in the positioning area, and finally positions the multiple battery cells 4 in the predetermined position. Combined with the transfer mechanism 6, the positioned battery cells 4 are placed into the battery cell clamp 5. Thus, the positioning of multiple closely adjacent battery cells 4 is achieved.

[0052] The transfer mechanism 6 pulls the battery cell 4 from the row spacing adjustment mechanism 3 onto the battery cell clamp 5. The transfer mechanism 6 includes a third linear movement component 601, an adsorption component, and a contact release component that opens the clamp 51. The adsorption component and the contact release component are connected to the output end of the linear movement component. There is one set of adsorption components, which are located on both sides of the contact release component.

[0053] The transfer mechanism 6 is a dual-station design. By placing two battery cells 4 with different orientations on the battery cell clamp 5, a dual-station feeding effect is achieved. At the same time, in the transfer mechanism 6, the adsorption components are located on both sides of the same contact release component. Therefore, the feeding process is optimized and the production capacity is faster.

[0054] In this embodiment, the flip angle of cell 4 is 90°.

[0055] Furthermore, the first clamping part 12 is a first pneumatic finger, and the second clamping part 11 is a second pneumatic finger.

[0056] Furthermore, the output end of the flipping mechanism 1 is provided with a first adsorption port 13a; the first adsorption port 13a is connected to an external vacuum generator, and the vacuum adsorption is a non-mechanical method to fix the battery cell 4, and the battery cell 4 is firmly adsorbed on the output end of the flipping mechanism 1 by negative pressure.

[0057] Furthermore, the flipping mechanism 1 includes a drive assembly, a suction cup 14, a clamping member 15, and a lifting cylinder 16. The clamping member 15 is formed by multiple baffles on the platform surface, which are arranged at intervals. A pressure groove 15a for placing the battery cell 4 is formed between the baffles. The lifting cylinder 16 is set in a posture where its output end moves towards the suction cup 14. The platform is set on the output end of the lifting cylinder 16. Multiple suction cups 14 are provided and connected to multiple output ends of the drive assembly. The suction cups 14 correspond to the aforementioned pressure grooves 15a. The purpose of adopting the above technical solution is to enable the battery cell 4 to be attracted by the suction cup 14. Since the battery cell 4 will undergo multiple transfers during the production process, some of the battery cells 4 will have certain deformation and be uneven. At this time, the inner side of the pressure groove 15a provides a support effect. Combined with the pneumatic fingers, the vertical battery cell 4 is flattened in a clamping posture to ensure that the battery cell 4 can be attracted by the suction cup 14.

[0058] Furthermore, the drive assembly includes a first drive cylinder 100, a rack 101, a slide plate 102, a support frame 103, and multiple drive units. Each drive unit includes a gear 104, a connecting shaft 105, a bearing seat 106, and a bearing. The surface of the support frame 103 is provided with a first slide rail, and the slide plate 102 is slidably connected to the first slide rail. The rack 101 is mounted on the slide plate 102. The output end of the first drive cylinder 100 is connected to the slide plate 102. The bearing seat 106 is mounted on the support frame 103. The gear 104 and the bearing are sleeved on the connecting shaft 105, which passes through the bearing seat 106. The bearing is located inside the bearing housing 106, and the gear 104 meshes with the rack 101. The purpose of adopting the above technical solution is to achieve synchronous control of multiple battery cells 4 by one drive source. In particular, the choice made for the structure of the suction cup 14 (the suction cup 14 includes an L-shaped transmission member 107 and an adsorption platform 108 located inside the transmission member 107, and the inner side of the transmission member 107 is provided with a suction head 109 passing through the adsorption platform 108) makes the suction cups 14 relatively compact. The specific implementation of the drive assembly has the advantage of having a small number of parts, which can satisfy the requirement of driving all the suction cups 14 to rotate in this space.

[0059] Furthermore, the output end of the first linear movement mechanism 1000 is provided with a pitch-changing module. The pitch-changing module includes a second drive cylinder 1001, a main board 1002, and multiple sets of scissor braces 1003 and fixed seats 1004. The fixed seats 1004 are spaced apart, and the surfaces of the fixed seats 1004 and the main board 1002 are slidably connected. The scissor braces 1003 are distributed on the surfaces of the fixed seats 1004 and the main board 1002. The scissor braces 1003 are rotatably connected end to end. In addition, the rotating end 1003' at the center of the scissor brace 1003 is also rotatably connected to the fixed seat 1004 and the main board 1002. The output end of the second drive cylinder 1001 is connected to any one of the fixed seats 1004. The specific method of this pitch-changing is that the pneumatic fingers are spaced apart. Using the scissor braces 1003, the spacing between multiple pneumatic fingers can be adjusted under the drive of a single power source. Moreover, after using the scissor braces 1003, the spacing adjustment between the pneumatic fingers is equal.

[0060] In this embodiment, a plurality of second linear moving mechanisms 1100 are also included to adjust the lateral position of the clamping member 15 and the suction cup 14, respectively.

[0061] Method of using this invention:

[0062] S1, Pre-adjust the position of suction cup 14 and the distance between it and the pneumatic finger;

[0063] S2, the first linear moving mechanism 1000 drives the suction cup 14 to take out the battery cell 4 from the material tray;

[0064] S3, the rotating mechanism 10 drives the first pneumatic finger to rotate, changing the orientation of the battery cell's 4 tabs;

[0065] S4, by driving the cylinder, the first suction port 13a of the suction cup 14 is kept in a position that can contact the side of the battery cell 4.

[0066] S5, the first linear moving mechanism 1000 moves the first pneumatic finger and the second pneumatic finger above the suction cup 14, and moves one side of the battery cell 4 in its vertical state onto the first suction port 13a. At the same time, the lifting cylinder 16 pushes the clamping member 15 to move towards the other side of the battery cell 4. Combined with the second linear moving mechanism 1100, the inner side of the pressure groove 15a applies pressure to the side of the battery cell 4, so that the battery cell 4 is adsorbed and fixed.

[0067] S6, the secondary execution of the drive cylinder causes the suction cup 14 to rotate in the opposite direction, causing the battery cell 4 to rotate 90°.

[0068] S7, stop evacuating cell 4, and cell 4 falls completely into pressure groove 15a.

[0069] The lifting mechanism 23 in the flattening mechanism 2 is a lifting cylinder.

[0070] The pressing part 21a and the pressure plate 21 are integrally formed. After the pressing part 21a and the pressure plate 21 are connected, they are L-shaped. The bottom surface of the pressing part 21a is the pressing surface of the electrode tab. The integral forming design makes the connection between the pressing part 21a and the pressure plate 21 more stable, and the L-shape can better apply pressure to the electrode tab.

[0071] Furthermore, a second adsorption port 20b is provided in the first positioning groove 20a; the second adsorption port 20b is connected to an external vacuum generator, and the negative pressure is used to fix the battery cell 4 in the first positioning groove 20a to prevent the battery cell 4 from shifting during the pressure adjustment process.

[0072] Furthermore, it also includes a positioning mechanism 22 and a transport mechanism 24 for transferring the battery cell 4 between various mechanisms. The positioning mechanism 22 includes a positioning main board 2201, a movable plate, a fixed plate 2203, a sliding assembly, and a push cylinder 2204. The push cylinder 2204 and the sliding assembly are mounted on the positioning main board 2201. There are two fixed plates 2203, which are mounted on the positioning main board 2201 and have a second positioning groove. There are two movable plates, which are distributed on the fixed plate 2203 and connected to the movable end of the sliding assembly. There are multiple push cylinders 2204, and their output ends are connected to the movable plates respectively. The movable plates have a frame structure, and the staggered overlap between the movable plates results in a partial border 2202-a / 2202-b of another movable plate within the enclosed area of ​​the movable plate. The sides of a / 2202-b are adapted to the shape of the battery cell 4; the positioning mechanism 22 recalibrates the position of the battery cell 4, and the subsequent conveying mechanism 24 places the calibrated battery cell 4 into the second positioning slot; the combination of the movable plates is to optimize the space of the entire positioning mechanism 22. In this specific embodiment, there are two movable plates, and the first movable plate 2205 and the second movable plate 2206 are staggered, so that part of the frame 2202-a of the first movable plate 2205 is located in the enclosed area of ​​the second movable plate 2206. Similarly, part of the frame 2202-b of the second movable plate 2206 is located in the enclosed area of ​​the first movable plate 2205. Both are moved closer to each other by the push cylinder 2204, and the battery cell 4 is moved by the aforementioned part of the frame 2202-a to adjust the position of the battery cell 4.

[0073] Furthermore, the conveying mechanism 24 includes a first linear moving component 200, the output end of which is provided with a suction plate, and the suction plate is provided with a plurality of suction nozzles; the first linear moving component 200 is the prior art, mainly used in conjunction with the suction nozzles to transfer the battery cell 4 from the positioning mechanism 22 to the first positioning groove 20a.

[0074] The positioning device is specifically designed for the clamping member 51 in this single-row symmetrical layout.

[0075] The positioning device includes a second part 31 that carries the battery cell clamp 5.

[0076] And a transfer mechanism 6 for extracting the battery cell 4 from the row spacing adjustment mechanism 3 onto the battery cell clamp 5, wherein the row spacing adjustment mechanism 3 includes a worktable 32 and a third movable plate 34 and a positioning plate 33 disposed on the worktable 32. The third movable plate 34 is disposed on the positioning plate 33 and has an end extending to the surface of the worktable 32. The end is slidably connected to the worktable 32 (in the embodiment, the end is connected to a sliding mechanism on the surface of the worktable 32). A positioning protrusion 33a provided on the positioning plate 33 and the side of the third movable plate 34 form a positioning area for constraining the battery cell 4. In the positioning area, there are multiple movable positioning components 36 that divide the positioning area into multiple slots.

[0077] The positioning device provided by the present invention is pre-set with multiple positioning slots for positioning multiple battery cells 4. The positioning protrusion 33a and the third movable plate 34 apply pressure to the side of the battery cell 4 along the length direction, so that the position of the battery cell 4 is adjusted to a certain extent in the predetermined position and direction. The positioning component 36 applies pressure to the side of the battery cell 4 along the width in the positioning area, and finally positions multiple battery cells 4 in the predetermined position. Combined with the transfer mechanism 6, the positioned battery cells 4 are placed into the battery cell clamp 5. Thus, multiple closely adjacent battery cells 4 are positioned.

[0078] In other words, the present invention applies pressure to the circumferential surface of the battery cell 4, uses the third movable plate 34 and the positioning protrusion 33a to determine the adjustment of the battery cell 4 in one direction, and then uses the movable positioning component 36 in the positioning area to adjust the battery cell 4 in another direction, thereby achieving the purpose of adjusting the position of the battery cell 4.

[0079] Furthermore, the positioning component 36 is a push plate, and the worktable 32 has openings at both ends extending towards the battery cell 4. The push plate is located inside the openings, and the other part is located on the worktable 32. Together with the third movable plate 34 and the positioning protrusion 33a, it forms a positioning area. The openings serve as a guide to ensure that the movement direction of the push plate does not deviate from its original trajectory, thereby enhancing the stability of use.

[0080] Furthermore, it also includes a first push cylinder 37 and a connecting plate 38 located below the worktable 32. Multiple push plates are mounted on the connecting plate 38, and the output end of the first push cylinder 37 is connected to the connecting plate 38. Using a cylinder drive method can save a lot of usage time. At the same time, a single connecting plate 38 drives multiple push plates to move, so the number of power sources required is relatively small, requiring only one cylinder to push.

[0081] Furthermore, it also includes a second push cylinder 39 mounted on the worktable 32. The output end of the second push cylinder 39 is connected to the third movable plate 34. The second push cylinder 39 serves as the power source for moving the third movable plate 34, which also plays a role in improving efficiency.

[0082] Furthermore, the transfer mechanism 6 includes a third linear moving component 600, an adsorption component, and a contact release component 601 for opening the clamping member 51. The adsorption component and the contact release component 601 are connected to the output end of the third linear moving component 600. There is one set of adsorption components, which are located on both sides of the contact release component 601. The transfer mechanism 6 is a separate design based on the current battery cell clamp 5. The positions for placing the battery cell 4 on the battery cell clamp 5 are located on both sides of the clamping member 51. The contact release component 601 is located between the two adsorption components and can smoothly transfer the position of the battery cell 4 to the battery cell clamp 5. Each set of adsorption components has two rows of multiple adsorption heads 60d. The two rows of adsorption heads 60d are staggered to meet the symmetrical layout of the single row of clamping members 51.

[0083] Furthermore, the contact release assembly 601 includes a pressure plate 61 and a plurality of pressure blocks 61a extending from the pressure plate 61. The pressure blocks 61a are opposite to the clamping member 51. The pressure blocks 61a apply pressure to the clamping member 51 through contact, causing the clamping member 51 to open. The advantage of this method is that the clamping member 51 can be opened completely at once, and the opening and closing angles of the clamping member 51 can be controlled synchronously.

[0084] In this embodiment, a second lifting mechanism 62 is also provided at the output end of the third linear moving component 600 to independently control the lifting and lowering of the pressure plate 61.

[0085] Furthermore, the second part 31 is equipped with a rotating mechanism, the output end of which is connected to a rotating plate that supports the battery cell clamp 5, for transferring the battery cell clamp 5 to other workstations.

[0086] Furthermore, a support member 7 is provided between the second part 31 and the row spacing adjustment mechanism. The top of the support member 7 is provided with a pulley, and the rotating plate is mounted on the pulley. When the pressure block 61a opens the clamping member 51, the support member 7 can support the pressure brought by the pressure block 61a and improve the service life of the rotating plate.

[0087] It should be noted that, due to the small spacing between the clamping parts 51, the spacing between the adsorption heads 60d needs to be adjusted. The adsorption assembly also includes a mounting plate 60a, a positioning slider, an adsorption cylinder 60b, and an adjusting screw. The mounting plate 60a is provided with a slide rail 60c, and the positioning slider is slidably connected to the slide rail 60c. In this embodiment, there are several positioning sliders, and the adsorption heads 60d are respectively disposed on the positioning sliders. The positioning sliders are connected by adjusting screws. Specifically, the first adjusting screw 60f on the first positioning slider 60e is threadedly connected to the second positioning slider 60g. The first adjusting screw 60f does not penetrate the second positioning slider 60g. Similarly, the second positioning slider 60g, the third positioning slider 60h, and the fourth positioning slider 60i are also configured in this way. The output end of the adsorption cylinder 60b is connected to the first positioning slider 60e on the edge. When the adsorption cylinder 60b pulls the first positioning slider 60e to move towards the center position of the side of the mounting plate 60a, the first adjusting screw 60f first moves into the threaded hole on the second positioning slider 60g by rotation, bringing it closer to the second positioning slider 60g. When the first adjusting screw 60f reaches the end of the threaded hole of the second positioning slider 60g, the first adjusting screw 60f pushes the second positioning slider 60g in a pushing manner, causing the second adjusting screw 60j on the second positioning slider 60g to move into the third positioning slider 60h in the same manner. The other positioning sliders move according to the same principle, so they will not be described in detail.
