[0002] With the development of energy technology, existing electronic devices require mobile power sources such as batteries to power the devices. Therefore, the supply chain of electronic equipment or electric vehicle manufacturers has a demand for battery cell assembly. The level and requirements of battery cell production lines are becoming increasingly higher, and the improvement of production line capacity is imminent.

[0031] See also Figures 1 to 4 According to an embodiment of the present invention, a battery cell gluing and stacking device 100 is provided, comprising: a picking piece 110, a stacking mechanism 120 and a gluing assembly 130. The picking piece 110 is used to pick up the battery cells 200 and the foam 300. The stacking mechanism 120 comprises a stacking platform 121, a transverse movement assembly 122 and a lifting assembly 123. The stacking platform 121 is provided with a stacking hole 1211, and the lifting assembly 123 is arranged corresponding to the stacking hole 1211. The lifting assembly 123 can move along the height direction of the stacking platform 121, and the transverse movement assembly 122 is used to drive the battery cells 200 to move along the length direction of the stacking platform 121. The lifting assembly 123 is used to stack the battery cells 200. The gluing assembly 130 is connected to the stacking platform 121, and the gluing assembly 130 is used to glue the battery cells 200.

[0032] During use of the battery cell gluing and stacking device 100, first, at the initial position, the lifting assembly 123 is located at the stacking hole 1211. When stacking begins, the picking component 110 places the battery cell 200 on the lifting component 123. Then, the gluing component 130 applies glue to the battery cell 200. Then, the picking component 110 picks up a layer of foam 300 and places it on the glued battery cell 200. Then, the gluing component 130 applies glue to the foam 300. After the gluing is completed, the picking component 110 picks up the next battery cell 200 and stacks it on the foam 300. Each time a battery cell 200 is stacked, the lifting assembly 123 drives the battery cell 200 to move downward, so that the gluing assembly always applies glue at the horizontal position of the stacking platform 121. When the set number of stacking layers is reached and the stacking is completed, the transverse moving assembly 122 supports the stacked battery cells 200 and moves them along the length direction of the stacking platform 121 for the subsequent unloading process. The battery cell gluing and stacking device 100 can automatically perform stacking and gluing at the same time without manual intervention, meets the requirements of automated production, and is beneficial to greatly improve the working efficiency of battery cell 200 processing and the convenience of unloading after the battery cells 200 are stacked.

[0033] In order to further understand and explain the height direction and length direction of the stacking platform 121, Figure 1 For example, the height direction of the stacking platform 121 is Figure 1 The direction indicated by any arrow on the center line S1 is the length direction of the stacking platform 121. Figure 1The direction indicated by any arrow on the center line S2.

[0034] Optionally, the picking member 110 may be an industrial robot, a collaborative robot, or other devices capable of completing the task of picking up the battery cells 200 .

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The lifting assembly 123 includes a lifting platform 1231, a first driving member 1232, and a first transmission member 1233. The lifting platform 1231 is connected to the first driving member 1232 via the first transmission member 1233. The first driving member 1232 drives the lifting platform 1231 to move along the height direction of the stacking platform 121. The lifting platform 1231 is used to stack the battery cells 200. In this way, the first driving member 1232 drives the first transmission member 1233 to move, and the first transmission member 1233 drives the lifting platform 1231 to move up and down, so that the battery cells 200 are lowered layer by layer during stacking, which facilitates the positioning and gluing of the gluing assembly 130, thereby simplifying the control program and improving the operational reliability of the gluing device for the battery cells 200.

[0036] It should be noted that the lifting platform 1231 is driven and connected to the first driving member 1232 through the first transmission member 1233, which should be understood as the lifting platform 1231 is connected to the first driving member 1232 through the first transmission member 1233, and the first driving member 1232 serves as a driving source to drive the first transmission member 1233 to move, and the first transmission member 1233 drives the lifting platform 1231 to move up and down.

[0037] Alternatively, the first driving member 1232 may be an electric motor, a pneumatic motor, a hydraulic motor or other driving devices. The first transmission member 1233 may be a gear, a screw transmission mechanism, a conveyor belt, a connecting rod or other transmission devices.

[0038] Specifically, see Figure 1 The first drive member 1232 is a servo motor. The first transmission member 1233 is a screw drive mechanism. The screw drive mechanism converts the servo motor's rotation into displacement, thereby moving the lifting platform 1231 up and down. The servo motor improves positioning accuracy, offers high reliability, and simplifies control, effectively ensuring the overall operational stability and reliability of the lifting assembly 123. This embodiment provides only one specific implementation of the first drive member 1232 and the first transmission member 1233, but is not intended to be limiting.

[0039] In one embodiment, see Figure 2The transverse movement assembly 122 includes a transverse movement support plate 1221, a second driving member 1222, and a second transmission member 1223. The transverse movement support plate 1221 is connected to the second driving member 1222 via the second transmission member 1223. The second driving member 1222 drives the transverse movement support plate 1221 to move along the length of the stacking platform 121. Thus, under the driving action of the second driving member 1222, the stacked battery cells 200 are supported by the transverse movement support plate 1221 and then driven by the second transmission member 1223 along the length of the stacking platform 121, entering the subsequent unloading and packaging operations.

[0040] Optionally, the second driving member 1222 may be an electric motor, a pneumatic motor, a hydraulic motor or other driving devices. The second transmission member 1223 may be a gear, a screw transmission mechanism, a conveyor belt, a connecting rod or other transmission devices.

[0041] Specifically, see Figure 1 , second drive member 1222 is a servo motor. Second transmission member 1223 is a screw drive structure. Thus, the screw drive mechanism converts the rotation of the servo motor into displacement, thereby causing the lateral movement of the transverse support plate 1221. The servo motor improves positioning accuracy, is highly reliable, and is easy to control, thereby effectively ensuring the overall operational stability and reliability of the translation assembly. This embodiment only provides a specific implementation of the second drive member 1222 and the second transmission member 1223, but is not limited thereto.

[0042] Specifically, see Figure 2 The transverse support plate 1221 is provided with a first through slot 1224, and the first through slot 1224 is for the lifting platform 1231 to pass through when it moves along the height direction of the stacking platform 121. In this way, in the initial position, the transverse support plate 1221 is directly below the lifting platform, and the first through slot 1224 is arranged corresponding to the lifting platform up and down. The shape of the first through slot 1224 can ensure that the lifting platform passes through, and the battery cells 200 are stacked down until the lifting platform descends to the position of the first through slot 1224. The battery cells 200 collide with the transverse support plate 1221, and the lifting platform descends again. The transverse support plate 1221 supports the battery cells 200, and the lifting platform is disconnected from the battery cells 200. This coordination method can avoid interference between the movement trajectory of the lifting component and the transverse component 122, simplify the handling action of the battery cells 200, and is conducive to improving the automatic operation reliability and stability of the battery cell 200 stacking and loading process, thereby helping to improve the overall use quality and work efficiency of the battery cell glue coating and stacking device 100.

[0043] In one embodiment, see Figure 2The stacking mechanism 120 further includes a transverse pressing assembly 124, which is connected to the transverse moving assembly 122 and is used to press against the stacked battery cells 200. In this way, during the transverse movement of the battery cells 200, the transverse moving support plate 1221 below supports the battery cells 200, while the transverse pressing assembly 124 above the battery cells presses against the upper portion of the battery cells 200. This improves the stability of the battery cells 200 during the transverse movement, reduces or even prevents the battery cells 200 from tipping over due to acceleration, and thus helps improve the overall quality of use and work efficiency of the battery cell glue coating and stacking device 100.

[0044] Specifically, see Figure 2 The transverse pressing assembly 124 includes a transverse pressing claw 1241, a transverse pressing screw 1242 and a fourth driving member 1243. The transverse pressing claw 1241 is driven and connected to the fourth driving member 1243 through the transverse pressing screw 1242. The fourth driving member 1243 drives the transverse pressing claw 1241 to move along the length direction of the stacking platform 121. Specifically, the fourth driving member 1243 is a servo motor. In this way, the movable transverse pressing claw 1241 can be used flexibly. When the battery cells 200 are stacked, the transverse pressing claw 1241 moves away to avoid affecting the stacking of the battery cells 200 on the lifting platform 1231. After the stacking is completed, the transverse pressing claw 1241 moves to the top of the battery cells 200 and presses the battery cells 200, thereby fixing the stacked battery cells 200 from the top and bottom, which is beneficial to improving the stability of the battery cells 200 during the transverse movement.

[0045] In one embodiment, see Figure 1 The glue applying assembly 130 includes a two-axis motion platform 131 and a glue applying machine 132. The two-axis motion platform 131 is set on the stacking table 121, and the glue applying machine 132 is connected to the two-axis motion platform 131. The two-axis motion platform 131 drives the glue applying machine 132 to move along the length and width directions of the stacking table 121. In this way, the two-axis motion platform 131 drives the glue machine 132 to move horizontally and vertically on the plane of the stacking platform 121. The glue machine 132 applies glue to the battery cells 200 and foams 300 stacked on the lifting platform at the position of the stacking hole 1211, and can increase the gluing area, set the gluing method and gluing route, such as square, S-shaped, Z-shaped and other gluing methods, which is beneficial to improve the gluing effect of the glue component 130 on the battery cells 200 and foams 300. At the same time, the two-axis motion platform 131 can set the path and reposition, and can perform gluing operations on battery cells 200 of different sizes, which is beneficial to improve the use quality and applicability of the glue component 130.

[0046] Further, see Figure 1 There are more than two glue spraying machines 132, and the two or more glue spraying machines 132 are all connected to the two-axis platform. Figure 1, there are three glue spraying machines 132, but the present invention is not limited thereto. In this way, it is beneficial to further enrich the glue spraying function of the glue spraying assembly 130 on the battery cell 200, improve the glue spraying effect of the glue spraying assembly 130, and thus improve the use quality of the glue spraying assembly.

[0047] In one embodiment, see Figure 1 and Figure 4 The battery cell glue coating and stacking device 100 also includes a unloading mechanism 140. The unloading component includes a unloading platform 141, a unloading tray 142 and a unloading displacement component 143. The unloading platform 141 is provided with a second passing groove 144. The second passing groove 144 is for the unloading platform 141 to pass through. The unloading tray 142 is driven and connected to the unloading displacement component 143. The unloading displacement component 143 is used to drive the unloading tray 142 to move along the width and height directions of the stacking platform 121. In this way, the stacked battery cells 200 are moved horizontally to the top of the unloading tray 142 through the transverse movement component 122, and then the unloading tray 142 moves upward through the first passing slot 1224, and the unloading displacement component 143 drives the unloading tray 142 to lift the stacked battery cells 200 to the height of the unloading platform 141, and then moves along the width direction of the stacking platform 121, and the unloading tray 142 transports the battery cells 200 to the unloading platform 141, and then moves downward and passes through the second passing slot 144. At this time, the stacked battery cells 200 are placed on the unloading platform 141 for workers to pack and unload, and the unloading platform 141 returns to its initial position for the next work cycle.

[0048] In order to understand and explain the width direction of the stacking platform 121, Figure 1 For example, the width direction of the stacking platform 121 is Figure 1 The direction indicated by any arrow on the center line S3.

[0049] Specifically, see Figure 3 The blanking displacement assembly 143 includes a blanking lifting member 1431 and a blanking transverse moving member 1432. The blanking tray 142 is connected to the blanking lifting member 1431, and the blanking lifting member 1431 is movably connected to the blanking transverse moving member 1432. The blanking transverse moving member 1432 drives the blanking lifting member 1431 to move along the width direction of the stacking platform 121, and the blanking lifting member 1431 drives the blanking tray 142 to move along the height direction of the stacking platform 121. In this way, the blanking lifting member 1431 can control the blanking tray 142 to move up and down, and the blanking transverse moving member 1432 can control the blanking lifting member 1431 to move laterally, thereby realizing the lifting and lowering and transverse movement of the battery cell 200. The structure is simple and the control is convenient, which is conducive to improving the working reliability and stability of the blanking mechanism 140.

[0050] In one embodiment, see Figure 1The unloading mechanism 140 also includes a pressing assembly 145. The pressing assembly 145 includes a pressing bracket 1451, a third driving member 1452 and a pressing block 1453. The pressing bracket 1451 is connected to the unloading platform 141, and the pressing block 1453 is drivingly connected to the third driving member 1452. The third driving member 1452 is connected to the pressing bracket 1451, and the third driving member 1452 is used to drive the pressing block 1453 to contact or move away from the battery cell 200. In this way, after the unloading tray 142 moves the stacked battery cells 200 onto the unloading platform 141, the pressing block 1453 contacts the top layer of the battery cells 200 through the action of the pressing assembly 145, which can prevent the battery cells 200 from falling over, thereby improving the working stability and reliability of the unloading mechanism 140.

[0051] Optionally, the third driving member 1452 may be a cylinder, a motor, an oil cylinder or other driving devices.

[0052] Specifically, see Figure 1 The third driving member 1452 is a cylinder. This has a fast response speed, simple control, and convenient operation, which is conducive to improving the working stability and reliability of the material pressing assembly 145. This embodiment only provides a specific implementation of the third driving member 1452, but is not limited to this.

[0053] Further, see Figure 1 There are at least two third driving members 1452 and pressing blocks 1453, and the two or more third driving members 1452 are all connected to the pressing bracket 1451. The pressing blocks 1453 and the third driving members 1452 are arranged one-to-one. This is conducive to providing more angles and directions for fixing the battery cells 200. At the same time, it can also fix battery cells 200 of different models and sizes without moving the pressing bracket 1451, which is conducive to further improving the use effect of the pressing assembly 145.

[0054] In one embodiment, see Figure 1 The unloading mechanism 140 further includes a cover plate 146, which is rotatably connected to the wall of the second through-slot 144. When the cover plate 146 is closed, the cover plate 146 covers at least a portion of the second through-slot 144. In this way, when the unloading displacement assembly 143 drives the unloading tray 142 to move, the unloading lifting member 1431 needs to pass through the unloading platform 141 from top to bottom. At this time, the cover plate 146 is opened to allow the unloading lifting member 1431 to pass through. When the unloading lifting member 1431 is below the unloading platform 141, the cover plate 146 is lowered to cover a portion of the second through-slot 144, allowing workers to more conveniently unload and pack the battery cells 200 stacked on the unloading platform 141, preventing the battery cells 200 from falling through the second through-slot 144, thereby improving the reliability and convenience of the unloading mechanism 140.

[0055] In one embodiment, see Figure 3 The unloading mechanism 140 further includes an unloading and pressing assembly 147, which is connected to the unloading lifting member 1431 and is used to press and cooperate with the battery cell 200. In this way, the transverse movement assembly 122 moves the battery cell 200 transversely to the end position of the second transmission member 1223. At this time, the unloading tray 142 is located below the transverse movement support plate 1221, and the unloading and pressing assembly 147 is located above the battery cell 200. Then the unloading tray 142 moves upward, so that the unloading tray and the unloading and pressing assembly 147 clamp the stacked battery cells 200 from top to bottom. The unloading transverse movement member 1432 drives the unloading lifting member 1431 to drive the battery cell 200 to rise. After rising to the height of the unloading platform 141, it moves along the width direction of the stacking platform 121 to transport the battery cell to the unloading platform 141. The cooperation between the blanking tray 142 and the blanking pressing assembly 147 is conducive to improving the reliability and stability of the battery cells 200 during transportation, and preventing the battery cells 200 from tipping over and falling.

[0056] Specifically, see Figure 3 The blanking and clamping assembly 147 includes a blanking and clamping claw 1471, a blanking and clamping screw 1472, and a fifth driving member 1473. The blanking and clamping claw 1471 is connected to the fifth driving member 1473 via the blanking and clamping screw 1472. The fifth driving member 1473 drives the blanking and clamping claw 1471 along the length of the stacking platform 121. This allows the movable blanking and clamping claw 1471 to prevent the paths of different components from overlapping when the battery cells 200 are transferred from the transverse support plate 1221 to the blanking tray 142, thereby improving the operational reliability of the blanking mechanism 140.

[0057] In one embodiment, see Figure 1 The battery cell glue coating and stacking device 100 further includes a placement table 150, which is disposed adjacent to the picking member 110. Thus, the placement table 150 can place different types of foam materials 300, thereby facilitating the picking of the picking member 110, thereby improving the ease of use and operational reliability of the battery cell glue coating and stacking device 100.

[0058] In one embodiment, see Figure 1 There are at least two pick-up units 110, stacking mechanisms 120, and glue-applying components 130. The two stacking mechanisms 120 are located on opposite sides of the blanking mechanism 140. Thus, if the production cycle allows, two stacking stations can be coordinated with one blanking mechanism 140, saving equipment production costs and improving production efficiency.

[0059] In one embodiment, see Figure 4The battery cell glue coating and stacking device 100 further includes an upper cover assembly 160, which is disposed on the stacking platform 121 and the unloading platform 141. In this way, the upper cover assembly 160 can protect the battery cell glue coating and stacking device 100, and can also prevent dust and pollution, which is conducive to improving work safety.

[0060] In one embodiment, see Figures 1 to 4 , a battery cell 200 stacking and unloading system, including any one of the battery cell glue coating and stacking devices 100 described above.

[0061] During use of the above-mentioned battery cell 200 stacking and unloading system, first, at the initial position, the lifting assembly 123 is located at the stacking hole 1211. When stacking begins, the picking component 110 places the battery cell 200 on the lifting component 123. Then, the gluing component 130 applies glue to the battery cell 200. Then, the picking component 110 picks up a layer of foam 300 and places it on the glued battery cell 200. Then, the gluing component 130 applies glue to the foam 300. After the gluing is completed, the picking component 110 picks up the next battery cell 200 and stacks it on the foam 300. Each time a battery cell 200 is stacked, the lifting assembly 123 drives the battery cell 200 to move downward, so that the gluing assembly always applies glue at the horizontal position of the stacking platform 121. When the set number of stacking layers is reached and the stacking is completed, the transverse moving assembly 122 supports the stacked battery cells 200 and moves them along the length direction of the stacking platform 121 for the subsequent unloading process. The battery cell gluing and stacking device 100 can automatically perform stacking and gluing at the same time without manual intervention, meets the requirements of automated production, and is beneficial to greatly improve the working efficiency of battery cell 200 processing and the convenience of unloading after the battery cells 200 are stacked.

[0062] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
