Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, specifically designing an automatic device for applying adhesive tape to battery cell protection boards. Background Technology

[0002] In the battery manufacturing industry, after bending both ends of the cell protection board, adhesive tape needs to be applied to fix the cell protection board. Existing equipment first applies the adhesive tape to the cell protection board, and then goes to another station to spread the extension of the adhesive tape onto the cell using rollers and other structures. This makes the entire process of applying and spreading the adhesive tape time-consuming, reducing overall production efficiency. Moreover, since the adhesive application and spreading are separate mechanisms, even a slight deviation in the position when applying the adhesive tape is difficult to completely correct during the subsequent roller spreading, resulting in inaccurate adhesive tape placement and affecting the fixing effect of the cell protection board. Utility Model Content

[0003] The purpose of this invention is to provide an automatic adhesive application device for battery cell protection boards that can improve the consistency and stability of adhesive application and increase production efficiency.

[0004] An automatic adhesive tape applicator for battery cell protection boards includes a machine base and a turntable device, a battery cell transport device, several adhesive tape applicators, and several adhesive tape feeding feeders mounted on the machine base. The battery cell transport device, adhesive tape applicators, and adhesive tape feeding feeders are arranged around the outer periphery of the turntable device. The turntable device is equipped with several battery cell fixtures, which can hold several battery cells. The adhesive tape applicators are used to pick up adhesive tape from the adhesive tape feeding feeders and then apply the adhesive tape to the head of the battery cell to fix the bent protection board.

[0005] In the above scheme, the cell handling device transports the cells to the cell fixture on the turntable device. After the cell fixture clamps the cells, it is rotated by the turntable device to the front of the adhesive tape applicator. The adhesive tape applicator automatically picks up the adhesive tape from the adhesive tape feeder and then applies the adhesive tape to the head of the cell, extending the tape onto the cell to fix the bent protective plate. By completing the application and application of adhesive tape through the adhesive tape applicator, the problem of adhesive tape position deviation can be avoided, thereby improving the consistency and stability of adhesive tape application. Several adhesive tape applicators and adhesive tape feeders are arranged to apply protective plate adhesive tape to several cells on the cell fixture in turn. The overall automation level is high, improving production efficiency.

[0006] Furthermore, the adhesive tape application device includes an adhesive tape application robot, a rotary drive assembly, an adhesive tape application mechanism, a first adhesive application mechanism, and a second adhesive application mechanism. The rotary drive assembly is connected to the execution end of the adhesive tape application robot, and the adhesive tape application mechanism is connected to the rotary drive assembly. The first adhesive application mechanism and the second adhesive application mechanism are respectively installed on both sides of the adhesive tape application mechanism. The adhesive tape application mechanism, the first adhesive application mechanism, and the second adhesive application mechanism cooperate to apply adhesive tape to the battery cell.

[0007] In the above solution, the adhesive application robot can drive the adhesive application mechanism, the first adhesive application mechanism, and the second adhesive application mechanism to move along a preset trajectory. The adhesive application mechanism, the first adhesive application mechanism, and the second adhesive application mechanism first pick up the adhesive paper on the adhesive paper feeder and apply the adhesive paper to the protective plate on the head of the battery cell. Then, the first adhesive application mechanism and the second adhesive application mechanism work together to apply the extension of the adhesive paper to the battery cell, realizing a seamless connection of the adhesive application process. This makes the entire application process more compact and efficient, further increasing the number of battery cells processed per unit time. The rotary drive component facilitates the adjustment of the positions of the adhesive application mechanism, the first adhesive application mechanism, and the second adhesive application mechanism to better pick up and apply the adhesive paper.

[0008] Furthermore, the adhesive application mechanism includes a first elastic sliding component, a connecting plate, and a vacuum suction plate. The first elastic sliding component is connected to the rotary drive component, the connecting plate is connected to the first elastic sliding component, and the vacuum suction plate is connected to the connecting plate.

[0009] In the above scheme, the vacuum suction plate is used to adsorb and apply the adhesive paper to the main body. The first elastic sliding component provides a good buffering effect during the adhesive application process. When the adhesive application mechanism is close to the battery cell to perform the adhesive application operation, the first elastic sliding component can elastically expand and contract according to the actual situation of the battery cell surface, so that the vacuum suction plate and the battery cell surface can fit better, avoiding excessive pressure that may be caused by rigid contact, and ensuring that the adhesive paper can be evenly attached to the protective plate at the head of the battery cell, thereby improving the stability and quality of adhesive application.

[0010] Furthermore, the first elastic sliding component includes a first base plate, a first fixing block, a first guide rail, a first slider, and a first connecting block. The first fixing block is installed at one end of the first base plate, the first guide rail is installed on the first base plate, the first slider is slidably disposed on the first guide rail, the first connecting block is connected to the first slider, one end of the first connecting block is connected to a first connecting shaft, the other end of the first connecting shaft is connected to the first fixing block, and a first spring is sleeved on the first connecting shaft.

[0011] In the above scheme, the first base plate is connected to the first elastic sliding component and the rotary drive component. When the vacuum suction plate with adhesive paper comes into contact with the surface of the battery cell, the vacuum suction plate will be subject to a certain resistance because the surface of the battery cell may be uneven or the adhesive application process requires a certain buffer pressure. At this time, the first connecting block will be displaced relative to the first fixed block, and the first spring will be compressed. The first guide rail and the first slider prevent the vacuum suction plate from shifting. The compression process of the first spring absorbs the impact force generated when the adhesive application mechanism comes into contact with the battery cell, thus avoiding rigid collisions that could damage the battery cell and the adhesive application mechanism.

[0012] Furthermore, the first adhesive application mechanism includes a first telescopic drive component, a second elastic sliding component, a third elastic sliding component, a first push plate, and a plurality of first vacuum push blocks. The first telescopic drive component and the second elastic sliding component are mounted on the connecting plate along a first direction. The driving end of the first telescopic drive component is connected to the second elastic sliding component. The third elastic sliding component is connected to the first elastic sliding component along a second direction. The first push plate is slidably connected to the third elastic sliding component. The plurality of first vacuum push blocks are connected to the first push plate.

[0013] In the above scheme, after the main body of the adhesive tape is attached to the protective plate, the first telescopic drive component drives the second elastic sliding component to continue moving along the first direction, that is, along the horizontal direction of the battery cell, which in turn drives the first push plate and the first vacuum push block to continue moving, so that the first vacuum push plate attaches the extension of the adhesive tape to the battery cell. The third elastic sliding component is connected to the second elastic sliding component along the second direction, that is, the direction perpendicular to the battery cell, so that when the first vacuum push plate applies adhesive, there is elastic buffering in both the horizontal and vertical directions of the battery cell, avoiding damage to the battery cell.

[0014] Furthermore, the second elastic sliding assembly includes a second guide rail, a second slider, a sliding plate, a connector, and a second connecting shaft. The second guide rail is mounted on the connecting plate, the second slider is slidably disposed on the second guide rail, the sliding plate is connected to the second slider, one end of the connector is connected to the sliding plate, and the other end is sleeved on the second connecting shaft. The second connecting shaft is connected to the driving end of the first telescopic driving member, and a second spring is sleeved on the second connecting shaft.

[0015] In the above scheme, after the main body of the adhesive tape is attached to the protective plate, the first telescopic drive component starts to work. Its drive end pushes the second connecting shaft to move along the horizontal direction of the battery cell. Since the connector is sleeved on the second connecting shaft, the movement of the second connecting shaft will drive the connector and the sliding plate connected to the connector to move. If resistance is encountered, such as the friction force on the surface of the battery cell when the extension of the adhesive tape is attached to the battery cell, the connector will generate a certain displacement relative to the second connecting shaft, so that the second spring is compressed. The compression of the second spring plays a buffering role, absorbing and dispersing the impact force generated by the resistance, and avoiding damage to the equipment and battery cell caused by rigid collision.

[0016] Furthermore, the third elastic sliding assembly includes a third guide rail, a third slider, a second fixing block, and a third connecting shaft. The third guide rail is connected to the sliding plate, the third slider is slidably disposed on the third guide rail, one end of the third connecting shaft is connected to the second fixing block, and the other end is movably disposed through the first push plate. A third spring is sleeved on the third connecting shaft.

[0017] In the above scheme, during the process of applying adhesive tape to the battery cell, the first vacuum pusher plate will be subjected to the vertical force of the battery cell. The first pusher plate will be displaced relative to the third connecting shaft, and the third spring will begin to be compressed. The compression process of the third spring absorbs and disperses this vertical impact force, playing an elastic buffering role, and preventing the first vacuum pusher plate from putting too much pressure on the battery cell and damaging it.

[0018] Furthermore, the second adhesive application mechanism includes a second telescopic drive member, a fourth elastic sliding component, a fifth elastic sliding component, a second push plate, and a plurality of second vacuum push blocks. The second telescopic drive member and the fourth elastic sliding component are mounted on the connecting plate along a first direction. The drive end of the second telescopic drive member is connected to the fourth elastic sliding component. The fifth elastic sliding component is connected to the fourth elastic sliding component along a second direction. The second push plate is slidably connected to the fifth elastic sliding component. The plurality of second vacuum push blocks are connected to the second push plate.

[0019] In the above scheme, after the main body of the adhesive tape is attached to the protective plate, the second adhesive application mechanism and the first adhesive application mechanism apply adhesive simultaneously. Specifically, the second telescopic drive component drives the fourth elastic sliding component to continue moving along the first direction, that is, along the horizontal direction of the battery cell, which in turn drives the second push plate and the second vacuum push block to continue moving. This causes the second vacuum push plate to attach the extension of the adhesive tape to the battery cell. The fifth elastic sliding component is connected to the fourth elastic sliding component along the second direction, that is, the direction perpendicular to the battery cell. This ensures that the second vacuum push plate provides elastic buffering in both the horizontal and vertical directions of the battery cell when applying adhesive, thus avoiding damage to the battery cell.

[0020] Furthermore, the battery cell handling device includes a linear motor module, a transfer plate, and a battery cell adsorption assembly. Multiple sets of the battery cell adsorption assemblies are connected to the transfer plate, and the transfer plate is connected to the linear motor module.

[0021] In the above scheme, the linear motor module converts electrical energy into mechanical energy for linear motion, driving the connected transfer plate to move along a preset path and speed. The transfer plate drives multiple sets of battery cell adsorption components to move together until they reach the battery cell storage location. After the battery cell adsorption components successfully adsorb the battery cell, the linear motor module works again, driving the transfer plate and the battery cell adsorption components with the adsorbed battery cell to transport the battery cell onto the battery cell fixture.

[0022] Furthermore, the battery cell adsorption assembly includes a lifting cylinder, a suction cup mounting plate, and a vacuum suction cup. The lifting cylinder is connected to the transfer plate, the suction cup mounting plate is connected to the output end of the lifting cylinder through a support plate, and the vacuum suction cup is mounted on the suction cup mounting plate.

[0023] In the above scheme, the lifting cylinder drives the suction cup mounting plate and the vacuum suction cup mounted on it to descend together via the support plate. The lifting cylinder can precisely control the descent distance, so that the vacuum suction cup accurately reaches the position where the battery cell is stored and makes contact with the surface of the battery cell. When the vacuum suction cup makes contact with the surface of the battery cell, the vacuum system is activated, creating a negative pressure inside the vacuum suction cup. Under the action of atmospheric pressure, the vacuum suction cup tightly adheres to the battery cell, ensuring that the battery cell will not fall off during transportation. After the vacuum suction cup successfully adheres to the battery cell, the output end of the lifting cylinder retracts, driving the suction cup mounting plate and the vacuum suction cup adsorbing the battery cell to rise to a certain height, preparing for subsequent transportation operations.

[0024] This utility model discloses an automatic adhesive tape application device for battery cell protection boards, which improves the consistency and stability of adhesive tape application and increases production efficiency. The battery cell transport device transports the battery cells to a battery cell fixture on a turntable. After the battery cell fixture clamps the battery cell, it rotates to the front of the adhesive tape application device via the turntable. The adhesive tape application device automatically picks up the adhesive tape from the adhesive tape feeder and then applies the adhesive tape to the head of the battery cell, extending the tape over the cell to secure the bent protection board. This adhesive tape application and application process avoids adhesive tape misalignment, thus improving the consistency and stability of the application. Several adhesive tape application devices and feeders are arranged to apply protective film tape to multiple battery cells on the battery cell fixture in turn, resulting in a high degree of automation and significantly improved production efficiency.

[0033] The following will describe in further detail an automatic adhesive tape applicator for battery cell protection boards according to specific embodiments and accompanying drawings.

[0034] like Figure 1 and Figure 2As shown in a preferred embodiment, the automatic adhesive tape applicator for battery cell protection boards of this utility model includes a machine base 1 and a turntable device 2, a battery cell transport device 3, several adhesive tape applicators 4, and several adhesive tape feeders 5 mounted on the machine base 1. The battery cell transport device 3, the adhesive tape applicators 4, and the adhesive tape feeders 5 are arranged around the outer periphery of the turntable device 2. The turntable device 2 is provided with several battery cell fixtures, which can hold several battery cells. The adhesive tape applicators 4 are used to pick up the adhesive tape from the adhesive tape feeders 5 and then apply the adhesive tape to the head of the battery cell to fix the bent protection board.

[0035] In the above embodiment, the cell handling device 3 transports the cell to the cell fixture on the turntable device 2. After the cell fixture clamps the cell, the turntable device 2 drives the cell fixture to rotate to the front of the adhesive tape applicator 4. The adhesive tape applicator 4 automatically picks up the adhesive tape from the adhesive tape feeder 5. Then, the adhesive tape applicator 4 applies the adhesive tape to the head of the cell and can also apply the extension of the adhesive tape to the cell, thereby fixing the bent protective plate. The adhesive tape applicator 4 completes the application and application of adhesive tape, which can avoid the problem of adhesive tape position deviation, thereby improving the consistency and stability of adhesive tape application and application. The overall automation level is high, which improves production efficiency.

[0036] In this embodiment, there are two sets of adhesive tape application device 4 and adhesive tape feeding feeder 5. The adhesive tape feeding feeder 5 is a conventional standard feeding feeder. Each battery cell fixture holds two battery cells. First, one set of adhesive tape application device 4 and adhesive tape feeding feeder 5 completes the adhesive tape application for one battery cell. Then, the turntable device 2 transports the battery cell fixture to the operating position of the other set of adhesive tape application device 4 and adhesive tape feeding feeder 5 to complete the adhesive tape application for the other battery cell, thereby improving production efficiency.

[0037] like Figure 2 and Figure 3As shown, in some embodiments, the adhesive tape application device 4 includes an adhesive application robot 41, a rotary drive assembly 42, an adhesive application mechanism 43, a first adhesive application mechanism 44, and a second adhesive application mechanism 45. The rotary drive assembly 42 is connected to the execution end of the adhesive application robot 41, and the adhesive application mechanism 43 is connected to the rotary drive assembly 42. The first adhesive application mechanism 44 and the second adhesive application mechanism 45 are respectively installed on both sides of the adhesive application mechanism 43. The adhesive application mechanism 43, the first adhesive application mechanism 44, and the second adhesive application mechanism 45 cooperate to apply adhesive tape to the battery cell. The adhesive applicator robot 41 drives the adhesive applicator 43, the first adhesive applicator 44, and the second adhesive applicator 45 to move along a preset trajectory. The adhesive applicator 43, the first adhesive applicator 44, and the second adhesive applicator 45 first pick up the adhesive paper on the adhesive paper feeder 5 and stick the adhesive paper on the protective plate of the battery cell head. Then, the first adhesive applicator 44 and the second adhesive applicator 45 work together to apply the extension of the adhesive paper to the battery cell, realizing a seamless connection of the adhesive paper application process, making the entire application process more compact and efficient, and further increasing the number of battery cells processed per unit time. The rotary drive component 42 facilitates the adjustment of the positions of the adhesive applicator 43, the first adhesive applicator 44, and the second adhesive applicator 45 for better adsorption and application of adhesive paper.

[0038] like Figures 3 to 6 As shown, in some embodiments, the adhesive application mechanism 43 includes a first elastic sliding component 431, a connecting plate 432, and a vacuum suction plate 433. The first elastic sliding component 431 is connected to the rotary drive component 42, the connecting plate 432 is connected to the first elastic sliding component 431, and the vacuum suction plate 433 is connected to the connecting plate 432. The vacuum suction plate 433 is used to adsorb and apply the main body of the adhesive paper. The first elastic sliding component 431 provides a good buffering effect during the adhesive application process. When the adhesive application mechanism 43 approaches the battery cell for adhesive application, the first elastic sliding component 431 can elastically expand and contract according to the actual situation of the battery cell surface, so that the vacuum suction plate 433 fits better with the battery cell surface, avoiding excessive pressure that may be caused by rigid contact, and ensuring that the adhesive paper can be evenly attached to the protective plate at the head of the battery cell, thereby improving the stability and quality of adhesive application.

[0039] like Figures 3 to 6 As shown, in some embodiments, the first elastic sliding assembly 431 includes a first base plate 4311, a first fixing block 4312, a first guide rail 4313, a first slider 4314, and a first connecting block 4315. The first fixing block 4312 is installed on one end of the first base plate 4311, the first guide rail 4313 is installed on the first base plate 4311, the first slider 4314 is slidably disposed on the first guide rail 4313, the first connecting block 4315 is connected to the first slider 4314, one end of the first connecting block 4315 is connected to a first connecting shaft, the other end of the first connecting shaft is connected to the first fixing block 4312, and a first spring 4316 is sleeved on the first connecting shaft.

[0040] The first base plate 4311 connects the first elastic sliding component 431 and the rotary drive component 42. When the vacuum suction plate 433 with adhesive paper adsorbed comes into contact with the surface of the battery cell, the vacuum suction plate 433 will be subject to a certain resistance because the surface of the battery cell may be uneven or the adhesive application process requires a certain buffering pressure. At this time, the first connecting block 4315 will be displaced relative to the first fixed block 4312, and the first spring 4316 will be compressed. The first guide rail 4313 and the first slider 4314 prevent the vacuum suction plate 433 from shifting. The compression process of the first spring 4316 absorbs the impact force generated when the adhesive application mechanism 43 comes into contact with the battery cell, thus avoiding rigid collisions that could damage the battery cell and the adhesive application mechanism 43.

[0041] like Figures 3 to 6 As shown, in some embodiments, the first adhesive application mechanism 44 includes a first telescopic drive member 441, a second elastic sliding component 442, a third elastic sliding component 443, a first push plate 444, and a plurality of first vacuum push blocks 445. The first telescopic drive member 441 and the second elastic sliding component 442 are mounted on the connecting plate 432 along a first direction. The drive end of the first telescopic drive member 441 is connected to the second elastic sliding component 442. The third elastic sliding component 443 is connected to the first elastic sliding component 431 along a second direction. The first push plate 444 is slidably connected to the third elastic sliding component 443. The plurality of first vacuum push blocks 445 are connected to the first push plate 444.

[0042] After the main body of the adhesive tape is attached to the protective plate, the first telescopic drive member 441 drives the second elastic sliding component 442 to continue moving along the first direction, that is, along the horizontal direction of the battery cell, which in turn drives the first push plate 444 and the first vacuum push block 445 to continue moving, so that the first vacuum push plate attaches the extension of the adhesive tape to the battery cell. The third elastic sliding component 443 is connected to the second elastic sliding component 442 along the second direction, that is, the direction perpendicular to the battery cell, so that when the first vacuum push plate applies adhesive, there is elastic buffering in both the horizontal and vertical directions of the battery cell, avoiding damage to the battery cell.

[0043] like Figures 3 to 6As shown, in some embodiments, the second elastic sliding assembly 442 includes a second guide rail, a second slider 4421, a sliding plate 4422, a connector 4423, and a second connecting shaft 4424. The second guide rail is mounted on the connecting plate 432, the second slider 4421 is slidably disposed on the second guide rail, the sliding plate 4422 is connected to the second slider 4421, one end of the connector 4423 is connected to the sliding plate 4422, and the other end is sleeved on the second connecting shaft 4424. The second connecting shaft 4424 is connected to the driving end of the first telescopic driving member 441, and a second spring 4425 is sleeved on the second connecting shaft 4424. After the main body of the adhesive tape is attached to the protective plate, the first telescopic drive 441 starts to work. Its drive end pushes the second connecting shaft 4424 to move horizontally along the battery cell. Since the connector 4423 is sleeved on the second connecting shaft 4424, the movement of the second connecting shaft 4424 will drive the connector 4423 and the sliding plate 4422 connected to the connector 4423 to move. If resistance is encountered, such as the friction force on the surface of the battery cell when the extension of the adhesive tape is attached to the battery cell, the connector 4423 will have a certain displacement relative to the second connecting shaft 4424, so that the second spring 4425 is compressed. The compression of the second spring 4425 plays a buffering role, absorbing and dispersing the impact force generated by the resistance, and avoiding damage to the equipment and battery cell caused by rigid collision.

[0044] like Figures 3 to 6 As shown, in some embodiments, the third elastic sliding assembly 443 includes a third guide rail 4431, a third slider 4432, a second fixing block 4433, and a third connecting shaft. The third guide rail 4431 is connected to the sliding plate 4422, the third slider 4432 is slidably disposed on the third guide rail 4431, one end of the third connecting shaft is connected to the second fixing block 4433, and the other end is movably disposed through the first push plate 444. A third spring 4434 is sleeved on the third connecting shaft. During the process of applying adhesive tape to the battery cell, the first vacuum push plate will be subjected to a vertical force from the battery cell, and the first push plate 444 will be displaced relative to the third connecting shaft. The third spring 4434 will begin to be compressed. The compression process of the third spring 4434 absorbs and disperses this vertical impact force, playing an elastic buffering role and preventing the first vacuum push block 445 from putting excessive pressure on the battery cell and damaging it.

[0045] like Figures 3 to 6As shown, in some embodiments, the second adhesive applicator 45 includes a second telescopic drive member 451, a fourth elastic sliding component 452, a fifth elastic sliding component 453, a second push plate 454, and a plurality of second vacuum push blocks 455. The second telescopic drive member 451 and the fourth elastic sliding component 452 are mounted on the connecting plate 432 along a first direction. The drive end of the second telescopic drive member 451 is connected to the fourth elastic sliding component 452. The fifth elastic sliding component 453 is connected to the fourth elastic sliding component 452 along a second direction. The second push plate 454 is slidably connected to the fifth elastic sliding component 453. The plurality of second vacuum push blocks 455 are connected to the second push plate 454.

[0046] After the main body of the adhesive tape is attached to the protective plate, the second adhesive application mechanism 45 and the first adhesive application mechanism 44 apply adhesive simultaneously. Specifically, the second telescopic drive member 451 drives the fourth elastic sliding component 452 to continue moving along the first direction, that is, along the horizontal direction of the battery cell, which in turn drives the second push plate 454 and the second vacuum push block 455 to continue moving, so that the second vacuum push plate attaches the extension of the adhesive tape to the battery cell. The fifth elastic sliding component 453 is connected to the fourth elastic sliding component 452 along the second direction, that is, the direction perpendicular to the battery cell, so that the second vacuum push plate has elastic buffering in both the horizontal and vertical directions of the battery cell when applying adhesive, thus avoiding damage to the battery cell.

[0047] like Figure 7 As shown, in some embodiments, the battery cell handling device 3 includes a linear motor module 31, a transfer plate 32, and battery cell adsorption components 33. Multiple sets of battery cell adsorption components 33 are connected to the transfer plate 32, and the transfer plate 32 is connected to the linear motor module 31. The linear motor module 31 converts electrical energy into mechanical energy for linear motion, driving the transfer plate 32 connected to it to move along a preset path and speed. The transfer plate 32 drives multiple sets of battery cell adsorption components 33 to move together until they reach the battery cell storage location. After the battery cell adsorption components 33 successfully adsorb the battery cell, the linear motor module 31 works again, driving the transfer plate 32 and the battery cell adsorption components 33 with the adsorbed battery cell to transport the battery cell onto the battery cell fixture.

[0048] like Figure 7As shown, in some embodiments, the battery cell adsorption assembly 33 includes a lifting cylinder 331, a suction cup mounting plate 332, and a vacuum suction cup. The lifting cylinder 331 is connected to the transfer plate 32, and the suction cup mounting plate 332 is connected to the output end of the lifting cylinder 331 via a support plate 333. The vacuum suction cup is mounted on the transfer plate 32. The lifting cylinder 331 drives the suction cup mounting plate 332 and the vacuum suction cup mounted on it to descend together via the support plate 333. The lifting cylinder 331 can precisely control the descent distance, so that the vacuum suction cup accurately reaches the position where the battery cell is stored and contacts the surface of the battery cell. When the vacuum suction cup contacts the surface of the battery cell, the vacuum system is activated, creating a negative pressure inside the vacuum suction cup. Under the action of atmospheric pressure, the vacuum suction cup tightly adsorbs the battery cell, ensuring that the battery cell will not fall off during transportation. After the vacuum suction cup successfully adsorbs the battery cell, the output end of the lifting cylinder 331 retracts, driving the suction cup mounting plate 332 and the vacuum suction cup adsorbing the battery cell to a certain height, preparing for subsequent transportation operations.

[0049] The working principle and process of this utility model are as follows: The battery cell transport device 3 transports the battery cell to the battery cell fixture on the turntable device 2. After the battery cell fixture clamps the battery cell, the turntable device 2 drives the battery cell fixture to rotate to the front of the adhesive application device 4. The adhesive application robot 41 drives the adhesive application mechanism 43, the first adhesive application mechanism 44, and the second adhesive application mechanism 45 to move along a preset trajectory. The adhesive application mechanism 43, the first adhesive application mechanism 44, and the second adhesive application mechanism 45 first absorb the adhesive paper. The adhesive tape on the feeder 5 is attached to the protective plate at the head of the battery cell. After the main body of the adhesive tape is attached to the protective plate, the first telescopic drive 441 drives the second elastic sliding component 442 to continue moving along the first direction, that is, along the horizontal direction of the battery cell. This causes the first push plate 444 and the first vacuum push block 445 to continue moving, so that the first vacuum push plate attaches the extension of the adhesive tape to the battery cell. The second adhesive application mechanism 45 works synchronously with the first adhesive application mechanism 44 to apply the adhesive tape to the battery cell to fix the battery cell protective plate.
