[0056] In related technologies, the process of coating battery cells with adhesive requires first positioning and fixing the battery cells, and then using manual labor or complex mechanical devices to wrap the adhesive tape around the designated position of the battery cells, which affects the efficiency of battery cell production.

[0057] The adhesive coating device provided in this application embodiment can accurately adhere the adhesive tape to the battery cell after the cell is received by the rotating mechanism. This effectively improves the adhesive application accuracy, reduces adhesive defects caused by positional deviations, and thus improves the pass rate of battery cell production.

[0058] Reference Figure 1 and Figure 2 This application provides a coating device, which includes:

[0059] Rotating mechanism 2, which can support battery cell 100 and drive battery cell to rotate around its own axis;

[0060] The adhesive dispensing and applying mechanism 4 is located on one side of the rotating mechanism 2. The adhesive dispensing and applying mechanism 4 includes a first-direction power component 4211, a second-direction power component 4212, and an adsorption plate 43. The first-direction power component 4211 can drive the adsorption plate 43 to move along the first direction, and the second-direction power component 4212 can drive the adsorption plate 43 to move along the second direction, which is the rotation axis direction of the rotating mechanism 2.

[0061] In the above embodiment, the rotation axis of the rotating mechanism 2 is the same as the axial direction of the battery cell 100, that is, the second direction is the axial direction of the battery cell 100 on the rotating mechanism 2, and the adsorption plate 43 can acquire the tape 201.

[0062] See Figure 1 The rotating mechanism 2 can accurately receive the delivered battery cell 100 and drive the battery cell 100 to rotate around its own axis, facilitating the adhesive application mechanism 4 to apply adhesive to the end of the battery cell circumferentially. When the battery cell rotates, the adhesive application mechanism 4 can perform adhesive application on the end of the battery cell circumferentially in a fixed position or during movement, simplifying the device structure while ensuring that the adhesive tape can be evenly and completely wrapped around the end of the battery cell, improving the accuracy and quality of adhesive application.

[0063] In the above embodiments, see Figure 3 The power component 42 of the adhesive dispensing and applying mechanism 4 includes a first power component 421, which includes a first-direction power component 4211 and a second-direction power component 4212. The first-direction power component 4211 and the second-direction power component 4212 can be devices such as motors, hydraulic cylinders, or pneumatic cylinders. The first direction can be... Figure 3 In the X direction, the first direction power component 4211 controls the adsorption plate 43 to move along the first direction, so that the tape on the adsorption plate 43 can be completely wrapped around the circumference of the battery cell; the second direction can be Figure 3 In the Y direction, the second direction power component 4212 drives the adsorption plate 43 along the second direction to adjust the position of the adsorption plate 43 in the axial direction of the battery cell 100 and ensure the accuracy of the adhesive application.

[0064] In one embodiment, the first power component 421 further includes a first connecting plate 4213. The moving end of the first directional power component 4211 is fixedly connected to the second directional power component 4212, and the moving end of the second directional power component 4212 is fixedly connected to the first connecting plate 4213. The second power component 422 is fixedly connected to the first connecting plate 4213. That is, the second power component 422 is connected to the second directional power component 4212 through the first connecting plate 4213, which facilitates the connection and power transmission between the first power component 421 and the second power component 422.

[0065] In some embodiments, the adsorption plate 43 is used to adsorb the tape 201;

[0066] When the adsorption plate 43 moves in the first direction, it can adhere the tape 201 to the end of the battery cell.

[0067] After the adsorption plate 43 picks up the tape, the second directional power component 4212 drives the adsorption plate 43 to approach the battery cell position along the axial direction of the battery cell 100. When the adsorption plate 43 is against the position of the battery cell to be glued, the rotating mechanism 2 drives the battery cell to rotate. At the same time as the battery cell rotates, the first directional power component 4211 drives the adsorption plate to move horizontally, thereby transferring the tape to the surface of the battery cell and completing the operation of wrapping the tape on the surface of the battery cell, which improves the accuracy and efficiency of the glue application.

[0068] In some embodiments, see Figure 3 The rotating mechanism 2 includes a rotating drive component 211 and a gripper assembly 22, with the gripper assembly 22 connected to the rotating end of the rotating drive component 211.

[0069] In the above embodiments, the drive component 21, including the rotary drive component 211, can convert other forms of energy such as electrical energy and hydraulic energy into mechanical energy, and provide continuous and stable power support for the rotation of the gripper assembly 22 through the rotating end, so as to meet the requirements for rotation speed and accuracy during the cell coating process.

[0070] See Figure 3 The gripper assembly 22 can accurately and reliably receive the battery cells conveyed by the conveying mechanism 1. The structural design of the gripper assembly 22 can match the shape of the battery cell, ensuring that the battery cell can be stably and safely fixed on the gripper assembly 22, and preventing the battery cell from being damaged or falling off during the receiving process.

[0071] After the gripper assembly 22 clamps the battery cell 100, driven by the rotary drive component 211, the rotary drive component 211 drives the gripper assembly 22 and the battery cell 100 to rotate together via its rotating end, thus realizing that the battery cell rotates around its own axis. Through precise rotation control, the adhesive application mechanism 4 can perform adhesive application operations at different positions on the end of the battery cell from a fixed position, simplifying the structure and movement trajectory of the adhesive application mechanism 4 and improving the adhesive application efficiency and accuracy.

[0072] In some embodiments, see Figure 3 The gripper assembly 22 includes an opening and closing drive component 212, a first gripper 221, and a second gripper 222.

[0073] The rotating end of the rotary drive component 211 is provided with an opening and closing drive component 212. The opening and closing drive component 212 is provided with a first gripper 221 and a second gripper 222, and can drive the first gripper 221 and the second gripper 222 to move closer to each other or further away from each other.

[0074] In the above embodiments, the rotary drive component 211 provides continuous and stable power support for the rotation of the opening and closing drive component 212, ensuring that the entire rotating mechanism 2 can operate at a preset speed and direction of rotation, meeting the requirements for rotation angle and speed during the battery cell coating process. The rotary drive component 211 drives the opening and closing drive component 212 to rotate, thereby causing the first gripper 221 and the second gripper 222 connected to the opening and closing drive component 212, as well as the clamped battery cell, to rotate together. This allows the battery cell end to contact the adhesive material evenly, achieving omnidirectional coating operation and improving the uniformity and quality of the coating.

[0075] The opening and closing drive component 212 can be a rotary cylinder. The opening and closing drive component 212 can precisely drive the first gripper 221 and the second gripper 222 to move closer or further apart, realizing the clamping and releasing of the battery cell. When clamping the battery cell, it ensures that the clamping force is moderate, which can firmly fix the battery cell without causing damage; when releasing the battery cell, it can smoothly and quickly release the battery cell, facilitating subsequent transport and processing.

[0076] In the above embodiment, the rotation drive component 211 and the opening / closing drive component 212 cooperate to achieve independent control and coordinated operation of the two movements: rotation and opening / closing. The rotation drive component 211 provides rotational power to the opening / closing drive component 212, enabling the battery cell to be rotated and coated with adhesive; the opening / closing drive component 212 controls the opening and closing of the first gripper 221 and the second gripper 222, realizing the clamping and release of the battery cell. This allows the rotation mechanism 2 to flexibly and efficiently complete the clamping, rotation, and release of the battery cell.

[0077] In one embodiment, see Figure 3 The rotary drive component 211 includes a motor 2111 and a rotary shaft 2112. The motor 2111 drives the rotary shaft 2112 to rotate via a belt or chain or other transmission component. The rotary shaft 2112 is connected to the opening and closing drive component 212, so as to drive the opening and closing drive component 212, the gripper assembly 22, and the battery cell 100 to rotate synchronously. The rotary shaft 2112 serves as an intermediate component connecting the motor 2111 and the opening and closing drive component 212, simplifying the structural design of the rotary mechanism.

[0078] In some embodiments, see Figure 3The coating device also includes a detection mechanism 3, which is used to detect the position of the battery cell on the rotating mechanism 2. The detection mechanism 3 includes a first detection component 31 and a second detection component 32, which are disposed on both sides of the battery cell position.

[0079] See Figure 3 The conveying direction of the battery cell 100 can be the X direction in the figure, and the rotation axis of the rotating mechanism 2 can be set along the Y direction to improve the structural compactness of the coating device; the Z direction is perpendicular to the XOY plane.

[0080] In the above embodiments, the tape unwinding mechanism 200 can unwind the tape 201, and the adhesive application mechanism 4 can obtain the tape 201 from the tape unwinding mechanism 200. After the detection mechanism 3 determines the position of the battery cell, the adhesive application mechanism 4 adjusts the position of the adsorption plate 43 according to the position of the battery cell detected by the detection mechanism 3 to ensure the accuracy of the adhesive application, thereby accurately wrapping the obtained tape around the end of the battery cell. Since the rotating mechanism 2 keeps the battery cell in a rotating state, the adhesive application mechanism 4 can continuously apply adhesive to the end of the battery cell in a relatively fixed manner, realizing efficient and precise adhesive application. Moreover, by precisely controlling the application position and length of the tape, the consistency of the adhesive wrapping quality of the battery cell is ensured, which helps to improve the overall performance and reliability of the battery cell.

[0081] In some embodiments, the first detection component 31 and the second detection component 32 can accurately measure and determine the position of the battery cell using precise sensors, measuring devices, and other components. By positioning the first detection component 31 and the second detection component 32 on opposite sides of the battery cell's transport direction, detection can be performed from two different directions, covering multiple parts of the battery cell and improving the efficiency of position detection.

[0082] In some embodiments, the adhesive dispensing and applying mechanism 4 can adjust the position of the adsorption plate 43 according to the position of the battery cell.

[0083] See Figure 1 After the battery cell 100 is received by the rotating mechanism 2, the detection mechanism 3 can detect the specific position of the battery cell 100 on the rotating mechanism 2 in real time and accurately. Since there may be positional deviations in the battery cell during transportation and reception, the detection mechanism can detect these deviations in a timely manner and feed the relevant information back to the control mechanism. The control mechanism makes corresponding adjustments to the adhesive application mechanism 4 based on the detection results to ensure that the adhesive application mechanism 4 can accurately wrap the adhesive tape on the battery cell, effectively improving the application accuracy, reducing the problem of poor application caused by positional deviations, and thus improving the pass rate of battery cell production.

[0084] In some embodiments, see Figure 3The first detection component 31 includes a first bracket 311 and a first sensor 312. The first sensor 312 is disposed on the first bracket 311 and has a first detection surface facing the cell position.

[0085] The first support 311 is provided with a first air hole 313, and the opening of the first air hole 313 faces the first detection surface.

[0086] In the above embodiments, the first support 311 can withstand the weight of components such as the first sensor 312 and the external forces that may be generated during the detection process, ensuring that the first sensor 312 is accurately and stably positioned during detection. The first sensor 312 can be a laser sensor, a vision sensor, an ultrasonic sensor, or other sensors, capable of accurately sensing the relevant position information of the battery cell.

[0087] The first support 311 is provided with a first air hole. The first air hole generates airflow that acts on the first detection surface of the first sensor 312, blowing away dust and other impurities on the first detection surface, preventing dust from falling on the first detection surface of the first sensor, keeping the first detection surface clean, and ensuring detection accuracy and reliability.

[0088] The second detection component 32 can be symmetrically arranged with the first detection component 31. The second detection component 32 includes a second bracket and a second sensor. The second sensor is disposed on the second bracket and has a second detection surface facing the battery cell position. A second air hole is provided on the second bracket, and the opening of the second air hole faces the second detection surface, which is beneficial to improving the accuracy and consistency of detection.

[0089] In some embodiments, see Figure 3 The adhesive coating device also includes a mounting base 5, and the rotating mechanism 2 and the detection mechanism 3 are all mounted on the mounting base 5.

[0090] In the above embodiments, the mounting base 5 can be fixedly installed to bear the weight of components such as the rotating mechanism 2 and the detection mechanism 3, as well as the external forces generated during operation, to ensure the stability of the position of the rotating mechanism 2 and the detection mechanism 3, thereby ensuring the accuracy and stability of the coating and detection process.

[0091] In one embodiment, the mounting base 5 includes a support 51 and a connecting rod 52, which are perpendicular to each other. The support 51 is used to mount the rotating mechanism 2, and the connecting rod 52 is used to mount the detection mechanism 3. The mounting base 5 provides stable support and a mounting position for the rotating mechanism 2, ensuring that the rotating mechanism 2 can operate accurately and stably, thereby achieving high-quality coating of the workpiece. The detection mechanism 3, which is set on the mounting base 5, can conveniently perform real-time detection of the workpiece during the rotation process, promptly detect problems in the coating process, and make adjustments and corrections, thereby improving the coating quality and production efficiency of the battery cell.

[0092] In some embodiments, see Figure 3 and Figure 4 The coating device also includes a conveying mechanism 1 and a lifting mechanism 6. The conveying mechanism 1 is used to convey the battery cell 100, and the rotating mechanism 2 can receive the battery cell 100 conveyed by the conveying mechanism 1.

[0093] The lifting mechanism 6 includes a first lifting component 61 and a second lifting component 62. The first lifting component 61 and the second lifting component 62 are disposed on both sides of the conveying mechanism 1 and are capable of lifting the battery cell to the battery cell position.

[0094] In the above embodiments, in the cell coating process, the conveying mechanism 1 is responsible for smoothly and orderly conveying the cell 100 from the previous process (such as cell manufacturing or pretreatment process) to the coating station, realizing the continuous flow of the cell on the coating production line, improving the conveying efficiency of the cell, and also facilitating the rotating mechanism 2 to receive the cell 100.

[0095] In one embodiment, see Figure 3 The conveying mechanism 1 includes a conveying platform 11 and multiple clamps 12, which are spaced apart on the conveying platform. The conveying platform provides a track or guide for the conveying of the clamps 12 and the battery cells, enabling the clamps 12 to move along a predetermined path and direction, ensuring that the battery cells can be accurately and orderly conveyed to the subsequent coating station, which helps to improve the automation level and production efficiency of the entire battery cell production line.

[0096] In the above embodiments, each clamp 12 can fix the battery cell, preventing it from shaking, shifting, or falling during transport. Reliable fixing ensures the battery cell remains stable during transport, providing an accurate positioning basis for subsequent adhesive application and improving adhesive application accuracy.

[0097] Multiple clamps 12 are spaced apart on the conveying platform, enabling the conveying mechanism 1 to transport multiple battery cells simultaneously. On the one hand, this improves the conveying efficiency of the battery cells and enables mass production; on the other hand, the reasonable spacing can avoid mutual interference between the battery cells.

[0098] The first lifting component 61 and the second lifting component 62 form a conveying channel 63. After the battery cell in the conveying channel 63 is conveyed above the two lifting components, the two lifting components move to lift the battery cell and separate it from the conveying mechanism 1. The first lifting component 61 and the second lifting component 62 lift the battery cell simultaneously from both sides of the conveying mechanism 1, which can effectively prevent the battery cell from tilting or shaking during the lifting process and improve the stability of the lifting process.

[0099] In one embodiment, the first lifting member 61 includes a first lifting drive member 611 and a first lifting portion 612, the first lifting portion 612 being connected to the first lifting drive member 611 and having a first arcuate groove 6121; and / or,

[0100] The second lifting component 62 includes a second lifting drive 621 and a second lifting part 622. The second lifting part 622 is connected to the second lifting drive 621 and has a second arcuate groove 6221.

[0101] In the above embodiments, the first lifting component 61 and the second lifting component 62 can be designed or adjusted according to the actual shape and size of the battery cell to ensure the stability of the battery cell lifting process through the first arc-shaped groove 6121 and / or matching the structure of the battery cell. Furthermore, for irregularly shaped battery cells, the shape and position of the contact surfaces of the lifting components can be adjusted to allow the first lifting component 61 and the second lifting component 62 to better fit the battery cell, achieving stable lifting of the battery cell.

[0102] In the above embodiments, after the battery cell is lifted to the battery cell position on the rotating mechanism 2, the relative position between the battery cell and the rotating mechanism 2 can be ensured to be accurate, thereby improving the reliability of the rotating mechanism 2 in clamping and fixing the battery cell.

[0103] In some embodiments, see Figure 3 The adhesive dispensing and applying mechanism 4 includes a fixed plate 41 and a second power component 422. The fixed end of the second power component 422 is connected to the fixed plate 41 through the first power component 421, and the moving end of the second power component 422 is provided with an adsorption plate 43.

[0104] In the above embodiments, the adsorption plate 43 can be used to adsorb the tape at the adhesive adsorption position and to wrap the tape around the battery cell at the adhesive application position.

[0105] In the above embodiments, the fixed installation of the fixing plate 41 ensures the structural stability of the entire adhesive dispensing and applying mechanism 4, preventing components from loosening or shifting due to vibration or external forces, thereby ensuring the accuracy and stability of the adhesive dispensing and applying process. Furthermore, the fixing plate 41 can integrate components with different functions, such as the power unit 42, improving the overall performance and efficiency of the equipment.

[0106] See Figure 3 The second power component 422 is mounted on the fixed plate 41 via the first power component 421. For example, the second power component 422 is connected to the fixed plate 41 via the second directional power component 4212 and the first directional power component 4211, providing stable support and fixation for the power component 42. Simultaneously, the second power component 422 drives the adsorption plate 43 to move via its moving end, enabling the adsorption plate 43 to move between the adhesive absorption position and the adhesive application position. The second power component 422 can precisely control the movement trajectory and position of the adsorption plate 43, allowing the adsorption plate 43 to accurately reach the adhesive absorption position to absorb the tape, and accurately wrap the tape around the battery cell at the adhesive application position, improving the accuracy and quality of tape application and ensuring the battery cell's encapsulation effect.

[0107] See Figure 3 The adsorption plate 43 can provide sufficient adsorption force to keep the tape stable at the adsorption position, ensuring the integrity and accuracy of the tape during movement.

[0108] When picking up the adhesive, the second power unit 422 can drive the adsorption plate 43 to move to a suitable adhesive picking height, so that the adsorption plate 43 can accurately contact the tape and firmly adsorb it; when applying the adhesive, the second power unit 422 can also accurately move the adsorption plate 43 to the height of the battery cell position, ensuring that the tape can be accurately wrapped on the battery cell, thus improving the accuracy of adhesive picking and applying.

[0109] The height of battery cells may vary depending on their size and specifications. The second power unit 422 can flexibly adjust the height of the adsorption plate 43 according to the actual height of the battery cell, enabling the adhesive application mechanism to adapt to the production needs of various battery cells and enhancing the versatility and adaptability of the equipment.

[0110] In some embodiments, see Figure 3 The second power component 422 includes a first sub-drive component 4221 and a second sub-drive component 4222. The second sub-drive component 4222 is connected to the first power component 421 through the first sub-drive component 4221, and the adsorption plate 43 is connected to the second sub-drive component 4222.

[0111] In the above embodiment, the first sub-driving member 4221 can drive the adsorption plate 43 to move to the adhesive adsorption position, and the second sub-driving member 4222 can drive the adsorption plate 43 to move to the adhesive application position.

[0112] In the above embodiments, the first sub-drive member 4221 and the second sub-drive member 4222 can be devices such as a motor, hydraulic cylinder, or pneumatic cylinder. The moving end of the first sub-drive member 4221 is fixedly connected to the second sub-drive member 4222, and the moving end of the second sub-drive member 4222 is fixedly connected to the adsorption plate 43. The first sub-drive member 4221 and the second sub-drive member 4222 can provide two strokes for the adsorption plate 43. The stroke provided by the first sub-drive member 4221 is used to adsorb the tape, and the stroke provided by the second sub-drive member 4222 is used to transfer the tape onto the battery cell.

[0113] The first sub-drive unit 4221 can precisely move the adsorption plate 43 to the adhesive suction position that is completely aligned with the tape supply position, enabling the adsorption plate 43 to accurately and reliably adsorb the tape, thus improving the accuracy and success rate of tape application. The second sub-drive unit 4222 can precisely move the adsorption plate 43 with the tape adsorbed to the adhesive application position that is completely aligned with the battery cell, ensuring that the tape can be accurately wrapped around the battery cell, thus improving the accuracy and quality of adhesive application.

[0114] In one embodiment, see Figure 5The second power component 422 also includes a second connecting plate 4223, which connects the first sub-drive component 4221 and the second sub-drive component 4222. Through the connection of the second connecting plate 4223, the first sub-drive component 4221 and the second sub-drive component 4222 form a stable mechanical structure, improving the reliability and stability of the power component. Furthermore, the second connecting plate 4223 can be designed according to actual installation space and structural requirements, reasonably adjusting the relative position and angle between the first sub-drive component 4221 and the second sub-drive component 4222, enabling the entire second power component 422 to achieve a compact and reasonable layout within a limited space.

[0115] In some embodiments, see Figure 1 and Figure 5 The adhesive wrapping device also includes an adhesive pulling mechanism 7, an adhesive clamping mechanism 8, and an adhesive cutting structure 9. The adhesive pulling mechanism 7 is used to pull one end of the adhesive tape of a set length, the adhesive clamping mechanism 8 is used to clamp the other end of the adhesive tape of a set length, and the adhesive cutting structure 9 is used to cut the adhesive tape of a set length.

[0116] The adhesive dispensing and applicating mechanism 4 can acquire a set length of adhesive tape.

[0117] In the above embodiment, a tape-pulling mechanism 7 may be provided on the fixing plate 41. The tape-pulling mechanism 7 is used to pull up a set length of tape. The tape-taking and applying mechanism 4 adsorbs the set length of tape pulled out by the tape-pulling mechanism 7 through the adsorption plate 43. Then, the tape-clamping mechanism 8 clamps the tape, and finally, the tape-cutting structure 9 cuts the set length of tape.

[0118] The tape pulling mechanism 7 accurately pulls the required length of tape according to preset parameters, ensuring consistent tape length for each wrapping operation and improving the stability and consistency of the wrapping quality. The tape clamping mechanism 8 ensures the tape maintains a stable position during cutting, tape picking, and application, preventing tape movement or loosening. The tape cutting structure 9 allows the cut tape segments to be used independently for subsequent wrapping, facilitating acquisition and operation by the tape picking and applying mechanism 4. The tape picking and applying mechanism 4 acquires tape of a set length and accurately wraps it around the battery cell. The tape picking and applying mechanism 4 acquires tape from the independent tape segments formed after pulling, clamping, and cutting, and then precisely applies the tape to the battery cell according to a preset motion trajectory and posture.

[0119] In one embodiment, see Figure 5The tape-pulling mechanism 7 includes a tape-pulling drive component 71, a tape-pulling gripper 72, and a tape-pulling connector 73. The tape-pulling drive component 71 can precisely control the movement speed, displacement, and acceleration of the tape-pulling gripper 72, thereby achieving precise control of the tape pulling length and meeting the tape length requirements of different tape-wrapping operations. The tape-pulling gripper 72 can adopt a jaw-type or suction cup-type structure to firmly clamp the tape and prevent the tape from slipping during the pulling process. The tape-pulling connector 73 connects the tape-pulling drive component 71 and the tape-pulling gripper 72, transmitting the power generated by the tape-pulling drive component 71 to the tape-pulling gripper 72, so that the tape-pulling gripper 72 performs the tape-pulling action according to a predetermined movement trajectory, ensuring that the power of the tape-pulling drive component 71 can be accurately and efficiently transmitted to the tape-pulling gripper 72.

[0120] In some embodiments, see Figure 5 The tape-cutting structure 9 includes a cutter 91, and when the cutter 91 cuts the tape, the angle between the cutter 91 and the tape is an acute angle.

[0121] In the above embodiments, the cutter 91 can move closer to or further away from the tape under the drive of the cutter drive member. When the angle between the cutter 91 and the tape is kept at an acute angle, the cutting edge of the cutter 91 can cut the tape more smoothly during the process of cutting into the tape, avoiding the cutter encountering greater resistance when cutting into the tape, and improving the cutting efficiency.

[0122] In some embodiments, see Figure 5 The adhesive coating device also includes an adhesive pressing mechanism 10, and the adhesive pressing mechanism 10 and the adsorption plate 43 are disposed on two pairs of sides of the adhesive adsorption position.

[0123] In the above embodiment, the adhesive pressing mechanism 10 and the adsorption plate 43 are respectively arranged on two pairs of sides of the adhesive suction position, so that the adhesive pressing mechanism 10 and the adsorption plate 43 can cooperate and work together during the adhesive wrapping process. The adsorption plate 43 can first use adsorption to initially position the tape at the adhesive suction position on one side of the tape, ensuring that the tape will not be displaced in subsequent operations. Subsequently, the adhesive pressing mechanism 10 can apply pressure to the tape on the other side of the tape to prevent the tape from detaching from the adsorption plate 43 during cutting.

[0124] In one embodiment, the pressing mechanism 10 includes a pressing drive 101 and a pressing block 102, which converts the power provided by the pressing drive 101 into pressure on the tape. Factors such as the shape, material, and surface treatment of the pressing block 102 all affect the pressing effect. For example, a pressing block 102 made of an elastic material such as rubber can act as a buffer during the pressing process, reducing damage to the tape and the object being coated.

[0125] This application also provides a winding device, which includes the above-described adhesive coating device.

[0126] In the above embodiments, after the battery cell is received by the rotating mechanism, the adhesive application mechanism of the winding equipment drives the movement of the adsorption plate through the first and second directional power components, which can accurately adhere the adhesive tape to the battery cell, effectively improving the adhesive application accuracy and reducing the problem of poor adhesive application caused by positional deviation, thereby improving the pass rate of battery cell production.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
