Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment manufacturing, specifically a cell feeding device. Background Technology

[0002] In lithium battery production, battery cells stored in trays need to be removed and loaded onto the cell processing station. The existing method involves conveying the trays containing the cells to the loading station via a roller conveyor. A robotic arm at the loading station then removes the cells from the trays and loads them onto the cell processing station. However, due to the small contact area between the conveyor rollers and the cell trays, slippage is common, resulting in slow pallet conveying speeds. Consequently, when the trays at the loading station are empty, the next tray containing cells cannot reach the loading station quickly due to slippage, causing loading delays and reducing production efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems in existing battery cell module production methods, this application provides a battery cell feeding device, the detailed technical solution of which is as follows:

[0004] A battery cell loading device includes an input mechanism, a pushing mechanism, a loading mechanism, and a tray unloading mechanism.

[0005] The push mechanism is located after the input mechanism;

[0006] The input mechanism is used to transport the tray containing the battery cells to the pushing mechanism, which in turn pushes the tray containing the battery cells to the loading station.

[0007] The feeding mechanism is located above the feeding station. The feeding mechanism is used to remove the battery cells from the tray and transport the removed battery cells to the next station.

[0008] The pallet unloading mechanism is located on the side of the loading station. The pallet unloading mechanism is used to transport the empty pallets located at the loading station to the pallet stacking station.

[0009] The battery cell loading device provided in this application involves an input mechanism that inputs a tray containing battery cells. Once the tray at the loading station is emptied and transported to the tray recycling station, a pushing mechanism receives a tray from the input mechanism and quickly pushes it to the loading station. Compared to existing loading devices, the battery cell loading device of this application improves battery cell loading efficiency.

[0010] In some embodiments, the pushing mechanism includes a conveying section and a pushing section, wherein: the input end of the conveying section is connected to the output end of the input mechanism, and the conveying section is provided with a buffer station and a loading station, wherein the loading station is located after the buffer station; the conveying section is used to convey the tray containing the battery cells input by the input mechanism to the buffer station for buffering; the pushing section is located below the conveying section, and the pushing section is used to grip the tray located at the buffer station and push the tray to the loading station.

[0011] Once the pallet at the loading station is emptied and removed from the loading station, the pushing mechanism can actively and quickly push the pallet containing the battery cells, which was input by the input mechanism, to the loading station, thereby improving the battery cell loading efficiency.

[0012] In some embodiments, the conveying unit includes a conveying section and a carrying section, wherein the carrying section is located after the conveying section; a buffer station is located on the conveying section, the conveying section being used to receive a tray containing battery cells input by the input mechanism, and to convey the tray containing battery cells to the buffer station; and a loading station is located on the carrying section, the carrying section being used to carry the tray pushed to the loading station by the pushing unit.

[0013] The first half of the conveying section is a conveying section with conveying capacity.

The second half of the conveying section is a carrying section without conveying capacity. It can ensure the carrying of the tray pushed into place by the pushing unit, so that the tray is kept at the loading station, making it convenient for the picking mechanism to remove the battery cells from the tray.

[0014] In some embodiments, the conveying section includes a first mounting bracket, a first conveying roller group, a second conveying roller group, and a conveying drive unit, wherein: the first conveying roller group includes a plurality of first conveying rollers spaced apart along the conveying direction of the conveying section on a first side edge of the first mounting bracket, and the first conveying roller group is used to support a first end of the tray; the second conveying roller group includes a plurality of second conveying rollers spaced apart along the conveying direction of the conveying section on a second side edge of the first mounting bracket, and the second conveying roller group is used to support a second end of the tray; the conveying drive unit is disposed on the first mounting bracket and is drively connected to the first conveying roller group and the second conveying roller group, and the conveying drive unit is used to drive the first conveying roller group and the second conveying roller group to rotate synchronously to convey the tray containing the battery cells to the buffer station; a first pushing space for avoiding the pushing part is formed between the first conveying roller group and the second conveying roller group.

[0017] By configuring the conveyor drive unit, it is possible to implement simultaneous drive of the first and second conveyor roller groups with only one conveyor drive component, thereby reducing drive costs.

[0018] In some embodiments, the carrying section includes a second mounting bracket, a first carrying roller group, and a second carrying roller group, wherein: the first carrying roller group includes a plurality of first carrying rollers spaced apart along the conveying direction of the conveying section on the first side edge of the second mounting bracket, and the first carrying roller group is used to carry the first end of the pallet; the second carrying roller group includes a plurality of second carrying rollers spaced apart along the conveying direction of the conveying section on the second side edge of the second mounting bracket, and the second carrying roller group is used to carry the second end of the pallet; a second pushing space for avoiding the pushing section is formed between the first carrying roller group and the second carrying roller group.

[0019] By configuring the support section, on the one hand, during the pallet pushing process, the support section can support and guide the pallet, thereby improving the stability of the pallet pushing by the pushing unit. On the other hand, the support section forms a pushing space to accommodate the pushing unit and allow it to move, ensuring that the pushing unit can push the pallet to the loading station.

[0020] In some embodiments, the pushing unit includes a first translation module, a mounting plate, and at least one clamping unit, wherein: the mounting plate is connected to a movable part of the first translation module, and the clamping unit is disposed on the mounting plate; the first translation module is used to drive the clamping unit to move back and forth between a buffer station and a loading station, and the clamping end of the clamping unit is configured to switch between a high clamping position and a low clearance position; when the clamping unit moves to the buffer station, the clamping end of the clamping unit rises to the high clamping position to clamp the tray located at the buffer station; when the clamping unit moves to the loading station, the clamping end of the clamping unit releases the tray and descends to the low clearance position.

[0021] A simple pusher unit is provided, which can quickly push the pallet from the buffer station to the loading station. Furthermore, after pushing, the pusher unit is positioned at a low, unobstructed position, so it does not interfere with the conveying process of the transport unit.

[0022] In some embodiments, the clamping unit includes a first sliding bracket, a second sliding bracket, a clamping drive member, a first clamping plate, a second clamping plate, a first lifting drive member, and a second lifting drive member, wherein: both the first sliding bracket and the second sliding bracket are slidably connected to the mounting plate and are both drive-connected to the clamping drive member disposed on the mounting plate; the first clamping plate is slidably and vertically connected to the first sliding bracket and is drive-connected to the first lifting drive member disposed on the first sliding bracket; the second clamping plate is slidably and vertically connected to the second sliding bracket and is drive-connected to the second lifting drive member disposed on the second sliding bracket. Connection; When the clamping unit moves to the buffer station, the first lifting drive and the second lifting drive respectively drive the first clamping plate and the second clamping plate to rise to the clamping high position, and the clamping drive drives the first sliding bracket and the second sliding bracket to slide towards the middle, so that the first clamping plate and the second clamping plate clamp the tray located at the buffer station; when the clamping unit moves to the loading station, the clamping drive drives the first sliding bracket and the second sliding bracket to slide apart to both sides, so that the first clamping plate and the second clamping plate release the tray, and the first lifting drive and the second lifting drive respectively drive the first clamping plate and the second clamping plate to descend to the avoidance low position.

[0023] By configuring the clamping unit, when it moves to the buffer station, it can rise to the high clamping position to grab the pallet located at the buffer station; when it moves to the loading station, it can release the pallet and descend to the low clearance position, allowing the pallet to fall to the loading station.

[0024] In some embodiments, the feeding mechanism includes a second translation module, a first lifting module, a mounting beam, a plurality of clamping components, and a distance adjustment component, wherein: the first lifting module is connected to a movable part of the second translation module, the mounting beam is connected to a movable part of the first lifting module, the second translation module is used to drive the mounting beam to translate, and the first lifting module is used to drive the mounting beam to lift; a plurality of clamping components are spaced apart on the mounting beam along the extension direction of the mounting beam, each clamping component is used to clamp and straighten a battery cell; the distance adjustment component is disposed on the mounting beam, and a plurality of clamping components are connected to a movable part of the distance adjustment component, the distance adjustment component is used to drive a plurality of clamping components to synchronously move closer to the middle of the mounting beam or separate to both sides, so as to adjust the distance between the battery cells clamped by two adjacent clamping components.

[0025] The feeding mechanism enables the adjustment of the spacing between battery cells during the feeding and handling process, thereby improving the battery cell feeding efficiency.

[0026] In some embodiments, the plurality of clamping components include a first clamping component, a second clamping component, a third clamping component, a fourth clamping component, and a fifth clamping component, wherein: the fifth clamping component is fixedly installed at the middle position of the mounting beam; the first clamping component and the third clamping component are slidably connected to the mounting beam and located on the first side of the fifth clamping component; the second clamping component and the fourth clamping component are slidably connected to the mounting beam and located on the second side of the fifth clamping component; the pitch adjustment component includes a pitch driving member, a first pitching member, and a second pitching member, wherein: the pitch driving member is used to simultaneously drive the moving ends of the first pitching member and the second pitching member to move; the first clamping component and the second clamping component are connected to the moving end of the first pitching member, and the first pitching member is used to drive the first clamping component and the second clamping component to move closer to the middle of the mounting beam or to separate to both sides; the third clamping component and the fourth clamping component are connected to the moving end of the second pitching member, and the second pitching member is used to drive the third clamping component and the fourth clamping component to move closer to the middle of the mounting beam or to separate to both sides.

[0027] An implementation method for a pitch adjustment component is provided, which only requires setting a pitch driving component to control four clamping components to slide closer to the middle clamping component or slide apart to both sides, thereby implementing the handling and pitch adjustment operation of five materials.

[0028] In some embodiments, the first pitching member includes a first driving pulley, a first driven pulley, and a first synchronous belt, wherein: the first driving pulley and the first driven pulley are rotatably mounted on a mounting beam, and the first synchronous belt is fitted onto the first driving pulley and the first driven pulley along the extending direction of the mounting beam; a first clamping assembly is fixedly connected to a first side body of the first synchronous belt, and a second clamping assembly is fixedly connected to a second side body of the first synchronous belt; the second pitching member includes a second driving pulley, a second driven pulley, and a second synchronous belt, wherein: the second driving pulley and the second driven pulley are rotatably mounted on the mounting beam, and the second driving pulley is coaxially arranged and fixedly connected to the first driving pulley, and the diameter of the second driving pulley is [missing information - likely a percentage] of the diameter of the first driving pulley. The second synchronous belt is mounted on the second driving pulley and the second driven pulley along the extension direction of the mounting beam; the third clamping assembly is fixedly connected to the first side belt body of the second synchronous belt, and the fourth clamping assembly is fixedly connected to the second side belt body of the second synchronous belt; the driving end of the pitch drive member is connected to at least one of the first driving pulley and the second driving pulley, and the pitch drive member is used to simultaneously drive the first synchronous belt and the second synchronous belt to rotate, so as to drive the first clamping assembly and the second clamping assembly to move synchronously closer to or away from the middle position of the mounting beam at a first speed, and the third clamping assembly and the fourth clamping assembly to move synchronously closer to or away from the middle position of the mounting beam at a second speed, wherein the second speed is twice the first speed.

[0029] Since the third and fourth clamping components are located outside the first and second clamping components, by setting the diameter of the second drive wheel to twice the diameter of the first drive wheel and driving the second and first drive wheels to rotate synchronously by the drive component, the moving speed of the third and fourth clamping components can be twice the moving speed of the first and second clamping components, thus ensuring that each clamping component achieves synchronous pitch change.

[0030] In some embodiments, the clamping assembly includes a base, a clamping member, a aligning drive member, and a aligning plate, wherein: the base is connected to a mounting beam; the clamping member is slidably connected to the base and is drively connected to the aligning drive member mounted on the base, and the clamping member is used to clamp the battery cell; the aligning plate is fixedly connected to the base and located on the side of the clamping member; the aligning drive member is used to drive the clamping member to slide toward the aligning plate, so that the battery cell clamped on the clamping member abuts against the aligning plate.

[0031] By configuring the clamping components, the clamping components can be used to correct the position of the battery cells after they are clamped.

[0032] In some embodiments, the first lifting module includes a fixed plate, a first lifting plate, a second lifting plate, a lifting drive motor, and a connecting plate, wherein: the fixed plate is connected to the movable part of the second translation module, and the fixed plate is provided with a first rack extending in a vertical direction; the first lifting plate is connected to the fixed plate and can slide up and down along the fixed plate, the second lifting plate is slidably connected to the first lifting plate and can slide up and down along the first lifting plate, and the second lifting plate is provided with a second rack extending in a vertical direction; the lifting drive motor is mounted on the first lifting plate, and a gear is provided on the drive shaft of the lifting drive motor, the gear is located between the first rack and the second rack, and meshes with the first rack and the second rack respectively; when the lifting drive motor drives the gear to rotate, the first lifting plate rises and falls at a third speed, and the second lifting plate rises and falls at a fourth speed, wherein the fourth speed is twice the third speed; a mounting beam is connected to the lower end of the second lifting plate.

[0033] By adjusting the lifting module settings, the lifting drive motor's lifting speed for the mounting beam was doubled, and the lifting drive stroke for the mounting beam was also doubled, ultimately improving the material loading efficiency.

[0034] In some embodiments, the pallet unloading mechanism includes a height detection component, a third translation module, a second lifting module, and a gripper assembly, wherein: the height detection component is disposed on the side of the loading station and is used to detect the battery cells carried by the pallet located at the loading station; the second lifting module is connected to the movable part of the third translation module, and the gripper assembly is connected to the movable part of the second lifting module; the third translation module and the second lifting module cooperate to drive the gripper assembly to translate and lift, so as to drive the gripper assembly to pick up the empty pallet from the loading station and transport the pallet to the pallet stacking station.

[0035] By setting up a height detection component, it can be confirmed whether all the battery cells in the topmost pallet have been removed. This ensures that after the loading mechanism empties the battery cells from a pallet, the unloading mechanism can promptly transport the empty pallet to the pallet stacking station.

[0072] 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.

[0073] like Figures 1 to 2 As shown, the battery cell feeding device in this embodiment includes an input mechanism 10, a pushing mechanism 20, a feeding mechanism 30, and a tray unloading mechanism 40, wherein:

[0074] The push mechanism 20 is located after the input mechanism 10.

[0075] The input mechanism 10 is used to transport the tray 100 containing the battery cells to the pushing mechanism 20, and the pushing mechanism 20 is used to push the tray 100 containing the battery cells to the loading station B.

[0076] like Figure 1 and Figure 2 Optionally, the input mechanism 10 may convey multiple stacked trays 100 containing battery cells to the pushing mechanism 20 each time, and the pushing mechanism 20 may push a stack of trays 100 containing battery cells to the loading station B each time. Alternatively, the input mechanism 10 may convey only one tray 100 containing battery cells to the pushing mechanism 20 each time, and the pushing mechanism 20 may push only one tray 100 containing battery cells to the loading station B each time.

[0077] The feeding mechanism 30 is located above the feeding station B. The feeding mechanism 30 is used to remove the battery cells from the tray 100 and transport the removed battery cells to the subsequent station. The tray unloading mechanism 40 is located on the side of the feeding station B. The tray unloading mechanism 40 is used to transport the empty tray 100 located at the feeding station B to the tray recycling station.

[0078] When the pushing mechanism 20 pushes a stack of trays 100 containing battery cells to the loading station B, after the loading mechanism 30 removes the battery cells from the topmost tray 100, the tray unloading mechanism 40 moves the empty tray 100 to the tray recycling station until all trays 100 are empty and moved to the tray recycling station.

[0079] As can be seen, the battery cell loading device provided in this application uses an input mechanism 10 to input a tray 100 containing battery cells. When the tray 100 at loading station B is emptied and transported to the tray recycling station, the pushing mechanism 20 immediately receives one tray 100 or a stack of trays 100 from the input mechanism 10 and quickly pushes the tray 100 to loading station B. Compared to existing loading devices, the battery cell loading device of this application improves battery cell loading efficiency.

[0080] like Figures 3 to 4 As shown, optionally, the pushing mechanism 20 includes a conveying section 21 and a pushing section 22, wherein: the input end of the conveying section 21 is connected to the output end of the input mechanism 10, and the conveying section 21 is provided with a buffer station A and a loading station B, wherein the loading station B is located after the buffer station A. The conveying section 22 is used to convey the tray containing the battery cells input by the input mechanism 10 to the buffer station A for buffering. The pushing section 22 is located below the conveying section 21, and the pushing section 22 is used to grip the tray located at the buffer station A and push the tray to the loading station B.

[0081] With the cooperation of the conveying unit 21 and the pushing unit 22, when the tray at the loading station B is emptied and moved out of the loading station B, the pushing mechanism 20 can actively and quickly push the tray containing the battery cells input by the input mechanism 10 to the loading station B, thereby improving the battery cell loading efficiency.

[0082] Optionally, the conveying unit 21 includes a conveying section 211 and a carrying section 212, wherein the carrying section 212 is located after the conveying section 211. A buffer station A is located on the conveying section 211, which receives a tray containing battery cells from the input mechanism 10 and conveys the tray to the buffer station A for buffering. A loading station B is located on the carrying section 212, which carries the tray pushed to the loading station B by the pushing unit 22.

[0083] The first half of the conveying unit 21 is a conveying section 211 with conveying capacity. After receiving the tray containing battery cells input by the input mechanism 10, the conveying section 211 can convey the tray to the buffer station A. The second half of the conveying unit 21 is a carrying section 212 without conveying capacity. It can ensure the carrying of the tray pushed into place by the pushing unit 22, so that the tray is held at the loading station B, so as to facilitate the picking mechanism to remove the battery cells from the tray.

[0084] Continue to refer to Figure 3 and Figure 4 As shown, optionally, the conveying section 211 includes a first mounting bracket 2111, a first conveying roller group 2112, a second conveying roller group 2113, and a conveying drive unit, wherein:

[0085] The first conveying roller group 2112 includes multiple rollers along the conveying direction of the conveying section 21 (e.g., ...). Figure 3 and Figure 4 The first conveyor rollers (in the direction indicated by the straight arrows in the diagram) are spaced apart on the first side edge of the first mounting bracket 2111, and the first conveyor roller group 2112 is used to support the first end of the pallet. The second conveyor roller group 2113 includes a plurality of second conveyor rollers spaced apart along the conveying direction of the conveying section on the second side edge of the first mounting bracket 2111, and the second conveyor roller group 2113 is used to support the second end of the pallet.

[0086] A conveying drive unit is mounted on the first mounting bracket 2111 and is connected to the first conveying roller group 2112 and the second conveying roller group 2113. The conveying drive unit drives the first conveying roller group 2112 and the second conveying roller group 2113 to rotate synchronously, so as to convey the tray containing the battery cells to the buffer station A. A first pushing space is formed between the first conveying roller group 2112 and the second conveying roller group 2113 to avoid the pushing part 22.

[0087] When the input mechanism 10 conveys the tray containing the battery cells toward the input end of the conveying section 211, the conveying drive unit drives the first conveying roller group 2112 and the second conveying roller group 2113 to rotate synchronously, so that the tray output by the input mechanism 10 is transferred onto the first conveying roller group 2112 and the second conveying roller group 2113. Then, the tray continues to be conveyed under the drive of the first conveying roller group 2112 and the second conveying roller group 2113. When the tray reaches the buffer station A, the conveying drive unit drives the first conveying roller group 2112 and the second conveying roller group 2113 to stop conveying, so that the tray is buffered at the buffer station A.

[0088] When the previous stack or pallet at the loading station B is emptied and removed from the loading station B, making the loading station B idle, the pushing unit 2 picks up the pallet containing the battery cells stored at the buffer station A and pushes the pallet to the loading station B through the first pushing space.

[0089] As can be seen, by configuring the conveying section 211 with a first conveying roller group 2112 and a second conveying roller group 2113 driven by the conveying drive unit, and setting a first pushing space between the first conveying roller group 2112 and the second conveying roller group 2113, it is ensured that the conveying section 211 can smoothly convey the pallet, so that the pallet is accurately conveyed to the buffer station A. On the other hand, it enables the pushing unit 22 to smoothly push the pallet at the buffer station A to the loading station B.

[0090] Continue to refer to Figure 3 and Figure 4 As shown, each of the first and second conveying rollers has a driven gear at its mounting end. The conveying drive unit includes a conveying drive component 2114, a rotating rod 2115, a first drive sprocket 2116, a second drive sprocket 2117, a first synchronous chain 2118, and a second synchronous chain 2119. The first end of the rotating rod 2115 is rotatably connected to the first side edge of the first mounting bracket 2111, and the second end of the rotating rod 2115 is rotatably connected to the second side edge of the first mounting bracket 2111. The first drive sprocket 2116 is fixedly mounted on the first end of the rotating rod 2115, and the second drive sprocket 2117 is fixedly mounted on the second end of the rotating rod 2115. The first synchronous chain 2118 is wound around the first drive sprocket 2116 and the driven gears of each of the first conveying rollers, and the second synchronous chain 2119 is wound around the second drive sprocket 2117 and the driven gears of each of the second conveying rollers. The conveying drive 2114 is connected to the rotating rod 2115 for transmission. The conveying drive 2114 is used to drive the rotating rod 2115 to rotate. When the rotating rod 2115 rotates, it drives each first conveying roller and each second conveying roller to rotate synchronously via the first synchronous chain 2118 and the second synchronous chain 2119.

[0091] By configuring the conveyor drive unit, it is possible to implement synchronous drive of the first conveyor roller group 2112 and the second conveyor roller group 2113 with only one conveyor drive component, thereby reducing the drive cost.

[0092] Optionally, the conveying section 211 further includes a first auxiliary roller group 2110, which includes a plurality of first auxiliary rollers 2110 spaced apart along the conveying direction of the conveying section 21 in the middle of the first mounting bracket 2111. The first auxiliary roller group 2110 is used to support the middle of the pallet.

[0093] When the first conveying roller group 2112 and the second conveying roller group 2113 convey and buffer the carrying pallet, the first auxiliary roller group 2110 supports the middle of the pallet, thereby further improving the conveying stability of the pallet by the conveying section 211 and improving the support strength of the pallet for the battery cells.

[0094] Continue to refer to Figure 3 and Figure 4 As shown, the carrying section 212 includes a second mounting bracket 2121, a first carrying roller group 2122, and a second carrying roller group 2123. The first carrying roller group 2122 includes a plurality of first carrying rollers spaced apart along the conveying direction of the conveying section 21 on the first side edge of the second mounting bracket 2121, and is used to carry the first end of the pallet. The second carrying roller group 2123 includes a plurality of second carrying rollers spaced apart along the conveying direction of the conveying section 21 on the second side edge of the second mounting bracket 2121, and is used to carry the second end of the pallet. A second pushing space, which avoids the pushing part, is formed between the first carrying roller group 2122 and the second carrying roller group 2123.

[0095] By configuring the carrying section 212 to include a first carrying roller group 2122 and a second carrying roller group 2123, on the one hand, during the process of the pushing unit 22 pushing the pallet, the carrying section 212 can support and guide the pallet, thereby improving the pushing stability of the pallet by the pushing unit 22. On the other hand, the carrying section 212 forms a pushing space to accommodate the pushing unit 22 and allow the pushing unit 22 to move, ensuring that the pushing unit 22 can push the pallet to the loading station B.

[0096] Optionally, the carrying section 212 may further include a second auxiliary roller group 2124, which includes a plurality of second auxiliary rollers spaced apart in the middle of the second mounting bracket 2121 along the conveying direction of the conveying section 21, and the second auxiliary roller group 2124 is used to carry the middle of the pallet.

[0097] During the process of pushing the pallet by the pushing unit 22, and when the pallet is pushed to the loading station B, the second auxiliary roller group 2124 supports the middle of the pallet, thereby further improving the pushing stability of the pallet by the pushing unit 22 and improving the support strength of the pallet for the battery cells.

[0098] like Figure 5 As shown, optionally, the pushing unit 22 includes a first translation module 221, a mounting plate 222, and at least one clamping unit 223, wherein: the mounting plate 222 is connected to the movable part of the first translation module 221, and the clamping unit 223 is disposed on the mounting plate 222. The first translation module 221 is used to drive the clamping unit 223 to move back and forth between the buffer station A and the loading station B, and the clamping end of the clamping unit 223 is configured to switch between a high clamping position and a low clearance position.

[0099] The process of pushing the pallet by the push unit 22 is as follows:

[0100] In the initial state, the clamping end of the clamping unit 223 is in a low position, that is, the clamping unit 223 is located below the bearing surface of the conveying part 21.

[0101] When it is necessary to push the tray at cache station A to loading station B, the first translation module 221 drives the clamping unit 223 to cache station A. Then, the clamping end of the clamping unit 223 rises to the clamping high position, and the clamping unit 223 clamps the tray located at cache station A.

[0102] The first translation module 221 drives the clamping unit 223 to translate to the loading station B, controls the clamping end of the clamping unit 223 to release the tray, and lowers it to the avoidance low position, so that the tray falls to the loading station B.

[0103] As can be seen, by configuring the pushing unit 22, it can quickly push the pallet at the buffer station A to the loading station B. Furthermore, after pushing, the pushing unit 22 descends below the bearing surface of the conveying unit 21, thus not interfering with the normal conveying operation of the conveying unit 21.

[0104] The first translation module 221 can adopt various existing linear drive modules that can drive the mounting plate 22 to translate, such as a screw drive module consisting of a screw motor, a screw and a nut, or a cylinder delivery module consisting of a cylinder, a slide rail and a slider.

[0105] Continue to refer to Figure 5As shown, the clamping unit 223 includes a first sliding bracket 2231, a second sliding bracket 2232, a clamping drive member 2233, a first clamping plate 2234, a second clamping plate 2235, a first lifting drive member 2236, and a second lifting drive member 2237. The first sliding bracket 2231 and the second sliding bracket 2232 are both slidably connected to the mounting plate 222 and are both drive-connected to the clamping drive member 2233 mounted on the mounting plate 222. The first clamping plate 2234 is slidably and vertically connected to the first sliding bracket 2231 and is drive-connected to the first lifting drive member 2236 mounted on the first sliding bracket 2231. The second clamping plate 2235 is slidably and vertically connected to the second sliding bracket 2232 and is drive-connected to the second lifting drive member 2237 mounted on the second sliding bracket 2232.

[0106] When the clamping unit 223 moves to the cache station A, the first lifting drive 2236 and the second lifting drive 2237 drive the first clamping plate 2234 and the second clamping plate 2235 to rise to the clamping high position, respectively. The clamping drive 2233 drives the first sliding bracket 2231 and the second sliding bracket 2232 to slide and move closer to the middle, so that the first clamping plate 2234 and the second clamping plate clamp the tray 2235 located at the cache station A.

[0107] When the clamping unit 223 moves to the loading station B, the clamping drive 2233 drives the first sliding bracket 2231 and the second sliding bracket 2232 to slide apart to both sides, so that the first clamping plate 2234 and the second clamping plate 2235 release the tray. The first lifting drive 2236 and the second lifting drive 2237 respectively drive the first clamping plate 2234 and the second clamping plate 2235 to descend to the avoidance low position.

[0108] Continue to refer to Figure 5 As shown, the pushing part 22 includes two clamping units 223, which are arranged side by side on the mounting plate 222. The two clamping units 223 clamp the tray from different positions, thereby improving the clamping stability of the tray and preventing the tray from tilting or slipping.

[0109] As those skilled in the art know, the spacing requirements of the downstream processing equipment at the downstream station for the battery cells are not necessarily the same as the storage interval of the battery cells in the tray. For example, if the battery cells are stored in the tray at a first spacing interval, the downstream processing equipment may require the battery cells to be loaded at a second spacing interval.

[0110] To enable cell spacing adjustment, the loading mechanism 30 can optionally include two transport mechanisms. One transport mechanism picks up several cells from the tray and places them on the spacing adjustment platform. The spacing adjustment platform then aligns and adjusts the spacing of the cells. Finally, the other transport mechanism transports the adjusted cells to the downstream processing equipment. Because the cells need to be transferred to the spacing adjustment platform for adjustment during the loading process, the loading efficiency of this structure is relatively low.

[0111] Therefore, this application embodiment also provides a feeding mechanism 30 with another structure, such as... Figure 6 and Figure 7 As shown, the feeding mechanism 30 includes a second translation module, a first lifting module 32, a mounting beam 33, several clamping components, and an adjustment component 39, wherein:

[0112] The first lifting module 32 is connected to the movable part of the second translation module, and the mounting beam 33 is connected to the movable part of the first lifting module 32. The second translation module is used to drive the mounting beam 33 to translate, and the first lifting module 32 is used to drive the mounting beam 33 to lift.

[0113] Several clamping components are spaced apart on the mounting beam 33 along the extension direction of the mounting beam 33, and each clamping component is used to clamp and straighten a battery cell.

[0114] The distance adjustment assembly 39 is mounted on the mounting beam 33. Several clamping assemblies are connected to the movable parts of the distance adjustment assembly 39. The distance adjustment assembly 39 is used to drive several clamping assemblies to move synchronously toward the middle of the mounting beam 33 or to separate to both sides, so as to adjust the distance between the cells clamped by two adjacent clamping assemblies.

[0115] The feeding process of the feeding mechanism 30 in this embodiment is as follows:

[0116] The spacing adjustment component 39 first adjusts the spacing between the clamping components to match the storage spacing of the battery cells in the tray, thus ensuring that each clamping component can be aligned with a battery cell component to be loaded.

[0117] Subsequently, the second translation module and the first lifting module 32 work together to drive the installation beam 33 to translate and lift, so that each clamping component can clamp a battery cell.

[0118] Next, the pitch adjustment component 39 drives several clamping components to move synchronously toward the center of the mounting beam 33 or separate to both sides until the spacing between the cells clamped by two adjacent clamping components is adjusted to the target spacing.

[0119] Finally, the second translation module and the lifting module 32 work together to drive the installation beam 33 to translate and lift, so that the battery cells of each clamping component can be placed in the subsequent work station.

[0120] As can be seen, the feeding mechanism 30 in this embodiment of the application realizes the adjustment of the spacing between the battery cells during the feeding and handling process, thereby improving the battery cell feeding efficiency.

[0121] Optionally, the clamping components include a first clamping component 34, a second clamping component 35, a third clamping component 36, a fourth clamping component 37, and a fifth clamping component 38, wherein: the fifth clamping component 38 is fixedly installed at the middle position of the mounting beam 333; the first clamping component 34 and the third clamping component 36 are slidably connected to the mounting beam 33 and located on the first side of the fifth clamping component 38; and the second clamping component 35 and the fourth clamping component 37 are slidably connected to the mounting beam 33 and located on the second side of the fifth clamping component 38.

[0122] The pitch adjustment assembly 39 includes a pitch drive 391, a first pitch component, and a second pitch component 393. The pitch drive 391 simultaneously drives the moving ends of the first pitch component 392 and the second pitch component 393. A first clamping assembly 34 and a second clamping assembly 35 are connected to the moving end of the first pitch component 392. The first pitch component 3921 drives the first clamping assembly 34 and the second clamping assembly 35 to move closer to the center of the mounting beam 33 or to separate to both sides. A third clamping assembly 36 and a fourth clamping assembly 37 are connected to the moving end of the second pitch component 393. The second pitch component 393 drives the third clamping assembly 36 and the fourth clamping assembly 37 to move closer to the center of the mounting beam 33 or to separate to both sides.

[0123] Before picking up a battery cell, the spacing drive 391 drives the moving ends of the first spacing component 392 and the second spacing component 393 to move, thereby adjusting the spacing between the first clamping assembly 34, the second clamping assembly 35, the third clamping assembly 36, the fourth clamping assembly 37, and the fifth clamping assembly 38 to match the storage spacing between the battery cells in the tray. Subsequently, driven by the cooperation of the second translation module and the first lifting module 32, the first clamping assembly 34, the second clamping assembly 35, the third clamping assembly 36, the fourth clamping assembly 37, and the fifth clamping assembly 38 each clamp a battery cell. Next, the spacing drive 391 drives the moving ends of the first spacing component 392 and the second spacing component 393 to move, causing the first clamping assembly 34, the second clamping assembly 35, the third clamping assembly 36, and the fourth clamping assembly 37 to move closer to the center of the mounting beam 33 or to separate to both sides, until the spacing between the five clamped battery cells is adjusted to the target spacing. Finally, driven by the cooperation of the second translation module and the first lifting module 32, the first clamping component 34, the second clamping component 35, the third clamping component 36, the fourth clamping component 37 and the fifth clamping component 38 place the five clamped battery cells to the downstream workstation.

[0124] like Figure 9 As shown, optionally, the first pitching member 392 includes a first driving pulley 3921, a first driven pulley 3922, and a first synchronous belt 3923, wherein: the first driving pulley 3921 and the first driven pulley 3922 are rotatably mounted on the mounting beam 33, and the first synchronous belt 3923 is fitted onto the first driving pulley 3921 and the first driven pulley 3922 along the extending direction of the mounting beam 33. The first clamping assembly 34 is positioned on the first side of the first synchronous belt 3923 (e.g., ...). Figure 9 The second clamping assembly 35 is fixedly connected to the second side (e.g., side C) of the first synchronous belt 3923, and is also fixedly connected to the second side (e.g., side C) of the first synchronous belt 3923. Figure 9 The D side of the belt is fixedly connected.

[0125] The second pitching component 393 includes a second driving pulley 3931, a second driven pulley 3932, and a second synchronous belt 3933. The second driving pulley 3931 and the second driven pulley 3932 are rotatably mounted on the mounting beam 333. The second driving pulley 3931 is coaxially arranged and fixedly connected to the first driving pulley 3921. The diameter of the second driving pulley 3931 is twice the diameter of the first driving pulley 3921. The second synchronous belt 3933 is fitted onto the second driving pulley 3931 and the second driven pulley 3932 along the extending direction of the mounting beam 33. The third clamping assembly 36 is positioned on the first side of the second synchronous belt 3933 (e.g., ...). Figure 9 The fourth clamping assembly 37 is fixedly connected to the second side (such as the C side) of the second synchronous belt 3933. Figure 9 The D side of the belt is fixedly connected.

[0126] The driving end of the pitch drive 391 is connected to at least one of the first drive pulley 3921 and the second drive pulley 3931. The pitch drive 391 drives the first synchronous belt 3923 and the second synchronous belt 3933 to rotate simultaneously via the first drive pulley 3921 and the second drive pulley 3931. The first synchronous belt 3923, through its two counter-rotating belt bodies, drives the first clamping assembly 34 and the second clamping assembly 35 to move synchronously towards or away from the middle position of the mounting beam 33 at a first speed. The second synchronous belt 3933, through its two counter-rotating belt bodies, drives the third clamping assembly 36 and the fourth clamping assembly 37 to move synchronously towards or away from the middle position of the mounting beam 33 at a second speed.

[0127] Since the third clamping assembly 36 and the fourth clamping assembly 37 are located outside the first clamping assembly 34 and the second clamping assembly 35, and the diameter of the second driving wheel 3931 is twice the diameter of the first driving wheel 3921, the moving speed of the third clamping assembly 36 and the fourth clamping assembly 37 is twice the moving speed of the first clamping assembly 34 and the second clamping assembly 35. In this way, it can be ensured that synchronous pitch change can be achieved between any two adjacent clamping assemblies during the pitch adjustment process.

[0128] Optionally, the first driving pulley 3921, the first driven pulley 3922, the second driving pulley 3931, and the second driven pulley 3932 all have meshing teeth. The first synchronous belt 3923 meshes with the first driving pulley 3921 and the first driven pulley 3922, respectively, and the second synchronous belt 3933 meshes with the second driving pulley 3931 and the second driven pulley 3932, respectively. This arrangement prevents slippage of the first synchronous belt 3923 and the second synchronous belt 3933, ensuring the variable pitch effect.

[0129] Optionally, the mounting beam 33 is also provided with a guide rail extending along the length of the mounting beam 33. The first clamping assembly 34, the second clamping assembly 35, the third clamping assembly 36, and the fourth clamping assembly 37 are all slidably connected to the guide rail via sliders. The guide rail provides sliding guidance for the first clamping assembly 34, the second clamping assembly 35, the third clamping assembly 36, and the fourth clamping assembly 37, preventing the clamping assemblies from deviating during the adjustment process.

[0130] like Figure 8 As shown, optionally, each clamping component in the embodiments of this application includes a base 341, a clamping member 342, a straightening drive member 343, and a straightening plate 344, wherein: the base 341 is connected to the mounting beam 33. The clamping member 343 is slidably connected to the base 341 and is drively connected to the straightening drive member 343 mounted on the base 341.

[0131] The clamping member 342 is used to clamp the battery cell, and the leveling plate 344 is fixedly connected to the base 341 and located on the side of the clamping member 342. After the clamping member 342 clamps the battery cell, the leveling drive member 343 drives the clamping member 342 to slide toward the leveling plate 344, so that the battery cell clamped on the clamping member 342 abuts against the leveling plate, thereby realizing the positional correction of the battery cell.

[0132] Optionally, the clamping member 342 includes a gripper cylinder 3421, a first clamping plate 3422 and a second clamping plate 3423, wherein the first clamping plate 3422 and the second clamping plate 3423 are connected to the two driving ends of the gripper cylinder 3421, and the gripper cylinder 3421 drives the first clamping plate 3422 and the second clamping plate 3423 to move closer to the middle or to separate to the sides, so as to grip or release the battery cell.

[0133] The second translation module can adopt various existing linear drive modules, such as a screw drive module consisting of a screw motor, a screw and a nut, or a cylinder drive module consisting of a cylinder, a slide rail and a slider.

[0134] Continue to refer to Figures 6 to 7As shown, optionally, the first lifting module 32 includes a fixed plate 321, a first lifting plate 322, a second lifting plate 323, a lifting drive motor 324, and a connecting plate 325, wherein: the fixed plate 321 is connected to the movable part of the second translation module, and a first rack extending vertically is provided on the fixed plate 321. The first lifting plate 322 is connected to the fixed plate 321 and can slide up and down along the fixed plate 321. The second lifting plate 323 is slidably connected to the first lifting plate 322 and can slide up and down along the first lifting plate 322. A second rack extending vertically is provided on the second lifting plate 323. The lifting drive motor 324 is mounted on the first lifting plate 322. A gear is provided on the drive shaft of the lifting drive motor 324. The gear is located between the first rack and the second rack and meshes with the first rack and the second rack respectively. A mounting beam 33 is connected to the lower end of the second lifting plate.

[0135] By configuring the first lifting module 32 in such a way that when the lifting drive motor 324 drives the gear to rotate, the first lifting plate 322 lifts and lowers at a third speed, and the second lifting plate 323 lifts and lowers at a fourth speed, wherein the fourth speed is twice the third speed.

[0136] In other words, by configuring the first lifting module 32, the lifting drive motor 324 doubles the lifting drive speed of the mounting beam 33, and the lifting drive stroke of the lifting drive motor 324 on the mounting beam 33 is also doubled accordingly.

[0137] Continue to refer to Figure 6 and Figure 7 As shown, optionally, the mounting beam 33 is rotatably connected to the movable part of the first lifting module 32. Correspondingly, the feeding mechanism 30 in this embodiment further includes a rotating module 310 connected to the movable part of the first lifting module 32. The rotating module 310 is used to drive the mounting beam 33 to rotate in the horizontal plane. By setting the rotating module 310, the feeding mechanism 30 in this embodiment can adjust the angle of the battery cells clamped on each clamping component during the feeding process, so that the battery cells are transported to the subsequent workstation at a predetermined angle.

[0138] like Figure 10 As shown, optionally, the pallet unloading mechanism 40 includes a third translation module 41, a second lifting module 42, and a gripper assembly 43, wherein: the second lifting module 42 is connected to the movable part of the third translation module 41, and the gripper assembly 43 is connected to the movable part of the second lifting module 42. The third translation module 41 and the second lifting module 42 cooperate to drive the gripper assembly 43 to translate and lift, so as to drive the gripper assembly 43 to pick up the empty pallet from the loading station B and transport the pallet to the pallet stacking station.

[0139] Both the third translation module 41 and the second lifting module 42 can adopt various existing linear drive modules, such as a screw drive module consisting of a screw motor, a screw and a nut, or a cylinder drive module consisting of a cylinder, a slide rail and a slider.

[0140] As mentioned above, in some embodiments, the pushing mechanism 20 pushes a stack of trays containing battery cells to the loading station B each time. After the loading mechanism 30 removes the battery cells from a tray, the tray unloading mechanism 40 transports the empty tray to the tray stacking station.

[0141] To ensure that the pallet unloading mechanism 40 can promptly transport the emptied pallets to the pallet stacking station, optionally, the pallet unloading mechanism 40 also includes a height detection component. The height detection component is located on the side of the loading station B and is used to detect the battery cells carried by the pallet located at the loading station B to determine whether all the battery cells in the pallet have been removed.

[0142] Optionally, the height detection component includes multiple sets of detection components, each consisting of a light generator and a photodetector, spaced vertically. Each set of detection components is used to detect the battery cells on each layer of the tray along the diagonal direction of the tray. When a battery cell is present in the topmost tray, the optical path of the detection component corresponding to that layer is blocked by the battery cell, generating a first signal. After receiving the first signal, the loading mechanism 30 continues to retrieve battery cells from the topmost tray. Once all the battery cells in the topmost tray have been removed, the optical path of the detection component at the corresponding height is no longer blocked by the battery cells, generating a second signal. After receiving the second signal, the tray unloading mechanism 40 removes the topmost tray.

[0143] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
