Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a deep-penetration cell bonding control method, equipment, and stacking machine. Background Technology

[0002] Solid-state batteries are batteries that use solid electrolytes instead of the separators and liquid electrolytes in traditional batteries. Solid-state lithium batteries can use lithium metal anodes instead of the graphite or silicon anodes in traditional lithium-ion batteries. Lithium metal anodes have higher energy density than traditional anodes, allowing the battery to store more energy in the same volume.

[0003] In related technologies, multiple electrode sheets need to be stacked to form a battery cell during the battery production process. However, in subsequent processes, there is a risk that the stacked electrode sheets may scatter or become misaligned, affecting the production quality of the battery. Summary of the Invention

[0004] This invention aims to at least solve the technical problems existing in related technologies. To this end, this invention proposes a deep-layer cell bonding control method, which is beneficial for maintaining the stacking stability of multiple electrode sheets and improving the production quality of batteries.

[0005] The present invention also proposes an apparatus and a stacking machine.

[0006] The first aspect of the present invention provides a method for controlling the deep bonding of adhesive to battery cells, comprising: The control transfer mechanism transfers the battery cell to the clamping station of the clamping mechanism; Control the clamping mechanism to clamp the battery cell located at the clamping station; Control the relative movement of the adhesive application mechanism and the clamping mechanism to the preset adhesive application position; The adhesive applicator is controlled to extend into the clamping mechanism to apply adhesive to the edges of the battery cell.

[0007] The deep-penetration battery cell adhesive application control method according to embodiments of the present invention has at least the following beneficial effects: This deep-penetration battery cell adhesive application control method can control the transfer mechanism to transfer the battery cell to the clamping station of the clamping mechanism, then control the clamping mechanism to clamp the battery cell located at the clamping station. Under the clamping action of the clamping mechanism, the multiple electrodes of the battery cell are kept in a stacked and tightly pressed state. Then, the adhesive application mechanism is controlled to move relative to the clamping mechanism to a preset adhesive application position, so that the adhesive application mechanism can align with the edge of the battery cell within the clamping mechanism. Finally, the adhesive application machine is controlled... The clamping mechanism applies adhesive to the edges of the battery cell, allowing the adhesive strips output by the adhesive application mechanism to adhere to the edges of multiple electrode sheets exposed on the outside of the clamping block. In other words, by applying adhesive to multiple electrode sheets that are kept stacked and compressed, the multiple electrode sheets are connected to each other. When the clamping force of the clamping mechanism is released, the multiple electrode sheets are connected as one unit by the connecting action of the adhesive strips. This also maintains the stacking stability of the multiple electrode sheets and effectively reduces the risk of multiple electrode sheets scattering or misaligning in subsequent processes, which is beneficial to improving the production quality of the battery.

[0024] Reference Figures 1 to 5 As shown, an embodiment of the present invention provides a method for controlling the deep bonding of adhesive to battery cells, comprising the following steps: Step S100: Control the transfer mechanism to transfer the battery cell 410 to the clamping station of the clamping mechanism 100; Step S200: Control the clamping mechanism 100 to clamp the battery cell 410 located at the clamping station; Step S300: Control the adhesive application mechanism 200 and the clamping mechanism 100 to move relative to each other to the preset adhesive application position; In step S400, the adhesive applicator 200 is controlled to penetrate the clamping mechanism 100 to apply adhesive to the edge of the battery cell 410.

[0025] Reference Figure 1 As shown, in step S100, the deep-penetration cell adhesive application control method controls the transfer mechanism to clamp and transfer the cell 410 to the clamping station of the clamping mechanism 100. The cell 410 includes multiple electrode sheets arranged in a stacked manner. Through the clamping and conveying of the transfer mechanism, the cell 410 can be conveyed to the clamping mechanism 100 while maintaining a stacked and compacted state, so as to maintain the transfer stability of the cell 410.

[0026] Reference Figure 1 As shown, in step S200, when the battery cell 410 is in the clamping position of the clamping mechanism 100, the deep-penetration battery cell adhesive control method can control the clamping mechanism 100 to clamp the battery cell 410 located in the clamping mechanism 100. That is, by applying clamping force to the battery cell 410, the battery cell 410 continues to be stacked and pressed, so that the relative positional relationship between multiple electrode sheets is more stable and compact.

[0027] Reference Figure 1 As shown, in step S300, considering the requirements for the adhesive application points and adhesive application actions of the battery cell 410, this deep-penetration battery cell adhesive application control method can control the adhesive application mechanism 200 and the clamping mechanism 100 to move relative to each other to a preset adhesive application position, so that the adhesive application mechanism 200 can be positioned relative to the edge of the battery cell 410 located at the clamping mechanism 100, thereby improving the positioning accuracy of the adhesive application mechanism 200 and the clamping mechanism 100.

[0028] Reference Figure 1As shown, in step S400, this deep-penetration cell adhesive application control method can control the adhesive application mechanism 200 to penetrate the clamping mechanism 100 to apply adhesive to the edge of the cell 410, thus attaching the adhesive strip 420 to the edge of the cell 410, connecting the adhesive strip 420 to the edges of multiple electrode sheets, and thus connecting the multiple electrode sheets to each other. Furthermore, this deep-penetration cell adhesive application control method can also apply adhesive to multiple points on the cell 410 to connect multiple electrode sheets into a single unit.

[0029] Reference Figure 1 As shown, this deep-layer cell adhesive application control method applies adhesive to multiple electrode sheets that are kept in a stacked and compressed state, so that the multiple electrode sheets are connected to each other. When the clamping force of the clamping mechanism 100 is released, the multiple electrode sheets are connected into one piece under the connecting action of the adhesive strip 420. This method can also maintain the stacking stability of multiple electrode sheets and effectively reduce the risk of multiple electrode sheets falling off or misaligning in subsequent processes, which is beneficial to improving the production quality of the battery.

[0030] Reference Figure 2 As shown, it can be understood that in step S300, the deep-penetration cell adhesive application control method controls the adhesive application mechanism 200 and the clamping mechanism 100 to move relative to each other to a preset adhesive application position, including the following steps: Step S310: Obtain adhesive application point information and timing sequence information. The adhesive application point information includes multiple preset adhesive application positions for the battery cell 410. The timing sequence information is used to determine the execution order of the multiple preset adhesive application positions. Step S320: Based on the adhesive application point information, determine at least one preset adhesive application position information, as well as the first point information and the second point information corresponding to the preset adhesive application position information. The first point information is used to characterize the spatial pose of the clamping mechanism 100, and the second point information is used to characterize the spatial pose of the adhesive application mechanism 200. Step S330: Determine the target adhesive application position information based on the timing sequence information. The target adhesive application position information is the preset adhesive application position information that needs to be applied in the current timing sequence. Step S340: Based on the first point information corresponding to the real-time target adhesive application position information, control the clamping mechanism 100 to move to a first position state that matches the spatial pose represented by the first point information. Step S350: Based on the second point information corresponding to the real-time target adhesive application position information, control the adhesive application mechanism 200 to move to a second position state that matches the spatial pose represented by the second point information, so that the adhesive application mechanism 200 and the clamping mechanism 100 are in the preset adhesive application position.

[0031] Reference Figure 2As shown, in step S310, this deep-penetration cell adhesive application control method can acquire adhesive application point information and timing sequence information. The adhesive application point information includes multiple preset adhesive application positions for the cell 410, including information such as the position where the clamping mechanism 100 and the adhesive application mechanism 200 cooperate to apply adhesive to the cell 410. The timing sequence information is used to determine the execution order of the multiple preset adhesive application positions. For example, if adhesive needs to be applied to 8 points on the cell 410, then the cell 410 corresponds to 8 preset adhesive application positions, and the timing sequence information is used to ensure the execution order of the 8 preset adhesive application positions, thereby ensuring the sequential execution of the 8 preset adhesive application positions.

[0032] Reference Figure 2 As shown, in step S320, the deep-penetration cell adhesive control method can establish a correspondence between the cell type and multiple preset adhesive application positions. During the process of controlling the transfer mechanism to transfer the cell 410 to the clamping mechanism 100, the cell type can be obtained by image capture or barcode scanning.

[0033] Reference Figure 2 As shown, the deep-penetration cell adhesive control method can then determine at least one preset adhesive application position information, as well as the first and second position information corresponding to the preset adhesive application position information, in the adhesive application position information according to the type of the cell 410.

[0034] Reference Figure 2 As shown, the first point information includes multi-axis point coordinates and horizontal rotation angles to characterize the spatial pose of the clamping mechanism 100. The second point information includes multi-axis point coordinates and horizontal rotation angles to characterize the spatial pose of the adhesive applicator 200.

[0035] Reference Figure 2 As shown, in step S330, the deep-penetration cell adhesive application control method can determine the target adhesive application position information based on the timing sequence information, that is, determine the preset adhesive application position information that needs to be applied in the current timing sequence from multiple preset adhesive application position information.

[0036] Reference Figure 2 As shown, in step S340, the deep-penetration cell adhesive application control method can obtain the first point information corresponding to the preset adhesive application position information that needs to be applied in the current time sequence based on the real-time target adhesive application position information, that is, obtain the first point information corresponding to the preset adhesive application position information that needs to be applied in the current time sequence, and then control the clamping mechanism 100 to move to the first position state that matches the spatial pose represented by the first point information through the moving mechanism 300.

[0037] Reference Figure 2As shown, in step S350, the deep-penetration cell adhesive application control method can obtain the second point information corresponding to the target adhesive application position information in real time, that is, obtain the second point information corresponding to the preset adhesive application position information that needs to be applied in the current time sequence, and then control the adhesive application mechanism 200 to move to the second position state that matches the spatial pose represented by the second point information through the moving mechanism 300.

[0038] Reference Figure 2 As shown, when the clamping mechanism 100 is in the first position and the adhesive applicator 200 is in the second position, the clamping mechanism 100 and the adhesive applicator 200 are in the preset adhesive applicator position, so that the adhesive applicator 200 can then penetrate the clamping mechanism 100 to perform the adhesive applicator action on the battery cell 410 in the clamping mechanism 100.

[0039] Reference Figure 2 As shown, this deep-penetration cell adhesive application control method can, after determining the target adhesive application position information, move the clamping mechanism 100 and the adhesive application mechanism 200 to the first position state and the second position state respectively according to the first point information and the second point information corresponding to the preset adhesive application position information required in the current timing sequence. This improves the positioning accuracy of the clamping mechanism 100 and the adhesive application mechanism 200, thereby ensuring the accuracy of subsequent adhesive application to the cell.

[0040] Reference Figure 3 As shown, it can be understood that in step S310, this deep-penetration cell adhesive application control method obtains adhesive application point information and timing sequence information, including the following steps: Step S311: Obtain the cell position information of cell 410; Step S312: When the cell position information is cell position information, obtain the cell attitude information of cell 410; Step S313: When the cell attitude information is the preset attitude information, obtain the adhesive application point information and timing sequence information.

[0041] Reference Figure 3 As shown, in step S311, this deep-penetration cell adhesive control method can obtain the cell position information of the cell 410 through sensing components such as photoelectric sensors.

[0042] Reference Figure 3 As shown, in step S312, when the deep-penetration battery cell adhesive application control method determines that the battery cell position information is battery cell in place, it is determined that the transfer mechanism has moved the battery cell 410 to the clamping position of the clamping mechanism 100. Then, the deep-penetration battery cell adhesive application control method can continue to acquire the battery cell attitude information of the battery cell 410.

[0043] Reference Figure 3As shown, for example, this deep-penetration cell adhesive control method can obtain the cell attitude information of the cell 410 by arranging photoelectric sensors at multiple end corners of the clamping station of the clamping mechanism 100.

[0044] Reference Figure 3 As shown, in step S313, when the deep-penetration cell adhesive application control method determines that the cell attitude information is the preset attitude information, the adhesive application point information and timing sequence information are obtained.

[0045] Reference Figure 3 As shown, for example, when multiple photoelectric sensors detect the obstruction of the battery cell 410, i.e., when multiple photoelectric sensors are triggered, the deep-penetration battery cell adhesive application control method determines that the acquired battery cell attitude information is the preset attitude information, and the placement attitude of the battery cell 410 is the preset attitude. Then, the deep-penetration battery cell adhesive application control method can continue to acquire adhesive application point information and timing sequence information about the battery cell 410.

[0046] Reference Figure 3 As shown, if the deep-penetration cell adhesive control method determines that the cell posture information is not the preset posture information, that is, the cell 410 has a large deviation in the placement posture of the clamping mechanism 100, a prompt message can be issued to indicate the offset of the cell 410, so as to adjust the position of the cell 410 in time and ensure the accuracy of subsequent adhesive application to the cell 410.

[0047] Reference Figure 4 As shown, it can be understood that in step S400 of this deep-penetration cell adhesive application control method, the adhesive application mechanism 200 is controlled to penetrate the clamping mechanism 100 to apply adhesive to the edge of the cell 410, including: In step S410, the adhesive applicator 200 is controlled to advance relative to the clamping mechanism 100 to a first preset depth, and the adhesive applicator 200 is controlled to raise to a first preset height, so that the adhesive strip 420 is attached to one end face of the battery cell 410. Step S420: Control the adhesive applicator 200 to descend to a second preset height, and control the adhesive applicator 200 to retract relative to the clamping mechanism 100 to the waiting position; Step S430: Control the adhesive applicator 200 to raise the third preset height so that the adhesive strip 420 is placed on the side of the battery cell 410; In step S440, the adhesive applicator 200 is controlled to advance relative to the clamping mechanism 100 to a second preset depth, and the adhesive applicator 200 is controlled to descend to a fourth preset height, so that the adhesive strip 420 is attached to the side and the other end face of the battery cell 410. In step S450, the cutter 240 is controlled to cut the adhesive strip 420 that is attached to the battery cell 410, and the adhesive application mechanism 200 is controlled to advance relative to the clamping mechanism 100 to a third preset depth to complete the adhesive application.

[0048] Reference Figure 4 As shown, in step S410, the deep-penetration cell adhesive application control method can control the adhesive application mechanism 200 to penetrate the clamping mechanism 100 to a first preset depth. The first preset depth is used to control the adhesive application length of the adhesive strip 420 on the lower surface of the cell 410. Then, the adhesive application mechanism 200 can be controlled to raise a first preset height. The first preset height can be the distance between the adhesive strip 420 and the surface of the cell 410, so that the adhesive strip 420 located below the cell 410 can adhere to the cell 410.

[0049] Reference Figure 4 As shown, in step S420, the deep-penetration cell adhesive application control method can control the adhesive application mechanism 200 to descend to a second preset height, for example, control the adhesive application mechanism 200 to descend by 1-2mm, thereby avoiding the problem of the adhesive application mechanism 200 scratching the cell 410. Then, the adhesive application mechanism 200 can be controlled to exit relative to the clamping mechanism 100 to a preset waiting position. In the preset waiting position, the adhesive application mechanism 200 and the clamping mechanism 100 do not have overlapping parts in the vertical direction.

[0050] Reference Figure 4 As shown, in step S430, the deep-penetration cell adhesive application control method can control the adhesive application mechanism 200 to rise to a third preset height. The third preset height can be slightly greater than the thickness of the cell 410, so that the adhesive strip 420 is placed on the side of the cell 410.

[0051] Reference Figure 4 As shown, in step S440, the deep-penetration cell adhesive application control method can control the adhesive application mechanism 200 to advance relative to the clamping mechanism 100 to a second preset depth, and control the adhesive application mechanism 200 to descend to a fourth preset height, so that the adhesive strip 420 is attached to the side and top surface of the cell 410, that is, the adhesive strip 420 is attached to the edge of the cell 410 in a C-shape, so that the edges of multiple electrode sheets are connected to each other as one.

[0052] Reference Figure 4 As shown, in step S450, the deep-penetration cell adhesive application control method can control the cutter 240 to cut the adhesive strip 420 bonded to the cell 410, thus segmenting the adhesive strip 420. Considering that there may be portions of the adhesive strip 420 that are not bonded to the cell 410 at the cut ends, the deep-penetration cell adhesive application control method can continue to control the clamping mechanism 100 to advance to a third preset depth, so that the separated adhesive strip 420 can be fully bonded to the cell 410, thus achieving complete bonding between the adhesive strip 420 and the cell 410.

[0053] Reference Figure 4As shown, this deep-penetration cell adhesive application control method uses the adhesive application mechanism 200 relative to the clamping mechanism 100 to apply the adhesive strip 420 in a C-shape to the side of the cell 410, thereby connecting the sides of multiple electrode sheets into a single unit. This deep-penetration cell adhesive application control method uses the adhesive application mechanism 200 to apply multiple adhesive strips 420 circumferentially to the cell 410, resulting in higher stability of the stacking and connection of multiple electrode sheets and reducing the risk of multiple electrode sheets scattering or misaligning in subsequent processes.

[0054] Reference Figure 5 As shown, it can be understood that in step S400, the deep-penetration cell adhesive application control method involves controlling the adhesive application mechanism 200 to penetrate the clamping mechanism 100 to apply adhesive to the edge of the cell 410, and then includes the following steps: In step S500, the adhesive applicator 200 is raised to the fifth preset height and retracted relative to the clamping mechanism 100 to the preset detection position. Step S600: Control the sensor to detect the position information of the adhesive strip on the battery cell 410; Step S700: When the adhesive strip position information is adhesive strip in place information, determine the next preset adhesive application position information as the new target adhesive application position information according to the timing sequence information.

[0055] Reference Figure 5 As shown, in step S500, after the adhesive strip 420 is applied to the battery cell 410, the deep-penetration battery cell adhesive application control method can control the adhesive application mechanism 200 to be raised to a fifth preset height, for example, 1-2mm, so that the adhesive application mechanism 200 is separated from the battery cell 410, thereby avoiding the problem of the adhesive application mechanism 200 causing scratches to the battery cell 410 due to movement.

[0056] Reference Figure 5 As shown, this deep-penetration cell adhesive application control method can drive the adhesive application mechanism 200 to retract relative to the clamping mechanism 100 to a preset detection position. In the preset detection position, the detection component for detecting the adhesive strip 420 is opposite to the adhesive strip 420 adhered to the cell 410.

[0057] Reference Figure 5 As shown, in step S600, the deep-penetration cell adhesive control method can control the detection component used to detect the position information of the adhesive strip on the cell 410, that is, detect whether the adhesive strip 420 is attached to the cell 410 according to the preset situation.

[0058] Reference Figure 5As shown, in step S700, when the deep-penetration cell adhesive application control method determines that the adhesive strip position information is adhesive strip in place information, that is, it is determined that the adhesive strip 420 has been attached to the cell 410, the preset adhesive application position information can be moved down to determine the new target adhesive application position information according to the timing sequence information.

[0059] Reference Figure 5 As shown, the deep-penetration cell adhesive application control method can then control the adhesive application mechanism 200 and the clamping mechanism 100 to move to the next preset adhesive application position and repeatedly execute the adhesive application action of the adhesive application mechanism 200 and the clamping mechanism 100 to achieve adhesive application at multiple positions and multiple edges on the same side of the cell 410, so that the edges of multiple electrode sheets are connected as one, so that multiple electrode sheets can be kept stacked and pressed, thereby reducing the problem of multiple electrode sheets detaching or misaligning with each other in subsequent processes.

[0061] The battery cell adhesive application equipment includes: a clamping mechanism 100, an adhesive application mechanism 200, and a moving mechanism 300.

[0062] Reference Figure 6 , Figure 7 and Figure 8 As shown, the clamping mechanism 100 includes a tensioning driver 120 and two clamping blocks 110. The tensioning driver 120 is connected to the two clamping blocks 110 to drive the two clamping blocks 110 to move closer or further apart in the vertical direction. When the battery cell 410 is placed between the two clamping blocks 110, the tensioning driver 120 can drive the two clamping blocks 110 to move closer to each other, and the two clamping blocks 110 can jointly apply a clamping force to the battery cell 410 from the upper and lower sides.

[0063] Reference Figure 6 , Figure 7 and Figure 8 As shown, the battery cell 410 includes multiple electrode sheets arranged in a stacked manner. The adhesive applicator of the battery cell can apply a clamping force to the battery cell 410 through the clamping mechanism 100, so that the multiple electrode sheets are kept in a stacked and compacted state.

[0064] Reference Figure 6 , Figure 7 and Figure 8 As shown, the adhesive applicator 200 is configured to output adhesive strip 420 to the clamping mechanism 100 and apply adhesive to the battery cell 410. The moving mechanism 300 is configured to drive the clamping mechanism 100 and the adhesive applicator 200 to move relative to each other. In conjunction with the adhesive applicator 200's application action, the adhesive strip 420 can be applied to the edges of multiple electrode sheets exposed on the outer side of the clamping block 110, so that the multiple electrode sheets are interconnected.

[0065] Reference Figure 6 , Figure 7 and Figure 8 As shown, the adhesive application equipment for this battery cell applies adhesive to multiple electrode sheets that are kept in a stacked and compressed state, so that the multiple electrode sheets are connected to each other. When the clamping force of the clamping mechanism 100 is released, the multiple electrode sheets are connected into one piece under the connecting action of the adhesive strip 420. This also maintains the stacking stability of the multiple electrode sheets and can effectively reduce the risk of multiple electrode sheets falling off or misaligning with each other in subsequent processes, which is conducive to improving the production quality of the battery.

[0066] Reference Figure 6 , Figure 7 and Figure 8 As shown, it should be noted that the opening and closing actuator 120 can be a linear drive mechanism such as an electric actuator, a pneumatic actuator, or a hydraulic actuator.

[0067] Reference Figure 6 , Figure 7 and Figure 8 As shown, it can be understood that the moving mechanism 300 includes a multi-axis moving assembly 310, which is connected to the clamping mechanism 100 and the adhesive applicator 200 to drive the clamping mechanism 100 and the adhesive applicator 200 to move along multiple axes.

[0068] Reference Figure 6 , Figure 7 and Figure 8 As shown, specifically, the multi-axis moving assembly 310 may include multiple linear drive mechanisms. The multi-axis moving assembly 310 can drive the adhesive applicator 200 to move linearly back and forth in the left and right direction. The multi-axis moving assembly 310 can also drive the clamping mechanism 100 to move linearly back and forth in the front and back direction. The adhesive applicator 200 includes an adhesive applicator head. The adhesive applicator 200 can drive the adhesive applicator head to move linearly back and forth in the up and down direction through a lifting driver, thereby attaching the adhesive strip 420 to the side of the battery cell 410.

[0069] Reference Figure 6 , Figure 7 and Figure 8As shown, the specific workflow is as follows: The multi-axis moving component 310 drives the adhesive applicator 200 to move in the left-right direction to position the adhesive strip 420 on the battery cell 410 in the left-right direction. Then, the multi-axis moving component 310 drives the adhesive applicator 200 to move in the front-back direction, cooperating with the upward movement of the adhesive applicator head, so that the upper adhesive surface of the adhesive strip 420 output by the adhesive applicator 200 adheres to the bottom surface of the battery cell 410. Then, the multi-axis moving component 310 drives the clamping mechanism 100 to move forward, cooperating with the upward movement of the adhesive applicator head, so that the adhesive strip 420 adheres to the side of the battery cell 410. Then, the multi-axis moving component 310 drives the clamping mechanism 100 to move backward, cooperating with the downward movement of the adhesive applicator head, so that the adhesive strip 420 adheres to the top surface of the battery cell 410.

[0070] Reference Figure 6 , Figure 7 and Figure 8 As shown, the adhesive application mechanism 200 of the battery cell adhesive application equipment can attach adhesive strips 420 in a C-shape to the side of the battery cell 410, so that the sides of multiple electrode sheets are connected to each other as a whole. The battery cell adhesive application equipment can attach multiple adhesive strips 420 to the circumference of the battery cell 410 through the adhesive application mechanism 200, so as to improve the stacking and connection stability of multiple electrode sheets, and reduce the risk of multiple electrode sheets scattering or misaligning in subsequent processes.

[0071] Reference Figure 6 , Figure 7 and Figure 8 As shown, it can be understood that the moving mechanism 300 includes a second rotary driver 320 connected to the clamping mechanism 100 to drive the clamping mechanism 100 to rotate relative to the adhesive applicator 200, so that the adhesive applicator 200 can apply adhesive to multiple edges of the battery cell 410.

[0072] Reference Figure 6 , Figure 7 and Figure 8 As shown, the second rotary driver 320 can drive the clamping mechanism 100 to rotate, switching the different edges of the battery cell 410 relative to the adhesive applicator 200. Under the movement drive of the moving mechanism 300, the adhesive applicator 200 can perform adhesive application on multiple long and short sides of the battery cell 410. This battery cell adhesive applicator can apply multiple adhesive strips 420 circumferentially to the battery cell 410 through the adhesive applicator 200, thereby improving the stacking and connection stability of multiple electrode sheets and reducing the risk of multiple electrode sheets scattering or misaligning in subsequent processes.

[0073] Reference Figure 6 , Figure 7 and Figure 8As shown, compared to the method of driving the adhesive applicator 200 to rotate, the adhesive applicator for this battery cell drives the clamping mechanism 100 to rotate, thereby switching the adhesive applicator 200 to apply adhesive to the long and short sides of the battery cell 410. This avoids the shaking or swaying of the adhesive strip 420 output by the adhesive applicator 200 caused by the rotation drive, and avoids problems such as inaccurate application or tangling of the adhesive strip 420 due to shaking or swaying, thus improving the production quality of the battery.

[0074] Reference Figure 7 , Figure 8 and Figure 9 As shown, it can be understood that the clamp 110 is provided with clearance notches 111 arranged at intervals along its circumference, the clearance notches 111 penetrating the side of the clamp 110 and the end face for abutting against the cell 410, and the adhesive applicator 200 is configured to apply adhesive to the portion of the electrode exposed in the clearance notches 111.

[0075] Reference Figure 7 , Figure 8 and Figure 9 As shown, the size of the adhesive application device clamp 110 is adapted to the size of the battery cell 410 to ensure that the main body and sides of the multiple electrode sheets are kept tightly stacked under the clamping action of the clamp 110. The clamp 110 is provided with clearance notches 111 arranged at intervals along its circumference, and the clearance notches 111 penetrate the side of the clamp 110 and the end face for the battery cell 410 to abut.

[0076] Reference Figure 7 , Figure 8 and Figure 9 As shown, the moving mechanism 300 can drive the adhesive applicator 200 to move relative to the clamping mechanism 100, so that the adhesive applicator 200 can move in and out of the clearance notch 111, thereby achieving adhesive application to the part of the electrode exposed in the clearance notch 111. The clearance notch 111 can be set in the preset adhesive application area of ​​the clamping block 110 corresponding to the electrode, so as to maintain the clamping effect of the clamping block 110 on the electrode while avoiding obstruction to the adhesive application of the adhesive applicator 200.

[0077] Reference Figure 7 , Figure 8 and Figure 9 As shown, the adhesive applicator for the battery cell drives the rotation of the clamping mechanism 100 through the moving mechanism 300, which can switch the long or short side clearance notch 111 of the clamping block 110 to face the adhesive applicator 200. The adhesive applicator 200 can enter and exit the clearance notch 111 of different edges of the clamping block 110 to achieve adhesive applicator processing on different edges of the battery cell 410.

[0078] Reference Figure 7 , Figure 8 and Figure 9As shown, it can be understood that the clamping block 110 is provided with at least two through slots 112 arranged along its width direction, the through slots 112 penetrating the side surface of the clamping block 110 and the end face for abutting against the battery cell 410. Specifically, the two ends of the through slots 112 respectively penetrate the two ends of the clamping block 110 along its length direction.

[0079] Reference Figure 7 , Figure 8 and Figure 9 As shown, the cell bonding equipment can cooperate with an external cell transfer mechanism. The cell 410 is typically transferred to the clamping mechanism 100 under the clamping action of the grippers. The through slot 112 provided in the clamping block 110 can be used to avoid the grippers of the cell transfer mechanism. That is, when the external cell transfer mechanism clamps the cell 410 between the two clamping blocks 110, the clamping mechanism 100 can directly control the opening and closing driver 120 to drive the two clamping blocks 110 closer to each other, and cause the grippers of the external cell transfer mechanism to enter the through slot 112, so as to realize the transfer of the cell 410 under a tight pressure state, so as to maintain the stacking stability of multiple electrode sheets and improve the production quality of the battery.

[0080] Reference Figure 7 , Figure 8 and Figure 9 As shown, the external battery cell transfer mechanism can then separate the gripper from the battery cell 410 and exit the clamping mechanism 100 through the through slot 112, thereby separating the clamping mechanism 100 from the external battery cell transfer mechanism.

[0081] Reference Figure 7 , Figure 8 and Figure 9 As shown, it is understood that the adhesive applicator for the battery cell also includes a first detection mechanism 510 adjacent to the clamping mechanism 100, which is configured to detect whether a battery cell 410 exists between the two clamping blocks 110.

[0082] Reference Figure 7 , Figure 8 and Figure 9 Specifically, the first detection mechanism 510 can be a photoelectric sensor, which detects the presence of a battery cell 410 by detecting any obstruction of the battery cell 410 located between the two clamping blocks 110. The clamping mechanism 100 is configured to operate based on the detection result of the first detection mechanism 510. When a battery cell 410 is present between the two clamping blocks 110, the clamping mechanism 100 can drive the two clamping blocks 110 to jointly clamp the battery cell 410, thereby improving the automation of the battery cell adhesive application equipment.

[0083] Reference Figure 7 , Figure 8 and Figure 9As shown, it is understood that the adhesive application device for the battery cell also includes a second detection mechanism 520 adjacent to the clamping mechanism 100, which is configured to detect the posture of the battery cell 410 in the clamping mechanism 100.

[0084] Reference Figure 7 , Figure 8 and Figure 9 As shown, the second detection mechanism 520 includes multiple photoelectric sensors arranged at multiple end corners of the clamping mechanism 100. The orientation of the battery cell 410 within the clamping mechanism 100 is detected by determining whether the multiple photoelectric sensors are triggered. For example, the second detection mechanism 520 includes four photoelectric sensors arranged at the four end corners of the clamping mechanism 100. When all four photoelectric sensors detect obstruction by the battery cell 410, it indicates that the orientation of the battery cell 410 at the clamping mechanism 100 conforms to a preset orientation.

[0085] Reference Figure 7 , Figure 8 and Figure 9 As shown, if some photoelectric sensors do not detect the obstruction of the battery cell 410, it indicates that the posture of the battery cell 410 at the clamping mechanism 100 does not conform to the preset posture. A prompt message can be issued to the user so that the user can adjust the relative position relationship between the battery cell 410 and the clamping mechanism 100 in a timely manner to improve the production quality of the battery.

[0086] Reference Figure 7 , Figure 8 and Figure 9 As shown, it should be noted that the detection principles and structures of the first detection mechanism 510 and the second detection mechanism 520 are conventional technical means in this field and will not be described in detail here.

[0087] Reference Figure 6 , Figure 10 and Figure 11 As shown, it can be understood that the adhesive applicator 200 includes a housing 220, a first rotary driver, and a plurality of conveying rollers 210 arranged in a planar manner. The housing 220 has a conveying channel 221. The adhesive strip 420 is wound around the plurality of conveying rollers 210 and passes through the conveying channel 221. The first rotary driver is configured to drive at least one conveying roller 210 to rotate.

[0088] Reference Figure 6 , Figure 10 and Figure 11As shown, the adhesive applicator for the battery cell can rotate one or more conveying rollers 210 by rotating the first rotary driver. The arrangement of multiple conveying rollers 210 can adjust the conveying direction of the adhesive strip 420 so that the unwound adhesive strip 420 passes through the conveying channel 221 of the housing 220. The end of the conveying channel 221 facing away from the conveying roller 210 can attach the output adhesive strip 420 to the battery cell 410.

[0089] Reference Figure 6 , Figure 10 and Figure 11 As shown, the conveying channel 221 ensures the straightness of the conveying of the adhesive strip 420 and supports the conveyed adhesive strip 420, which helps to avoid the problem of poor adhesive application or adhesive failure caused by the adhesive strip 420 bending due to its own material properties.

[0090] Reference Figure 6 , Figure 10 and Figure 11 As shown, specifically, the conveyor roller 210 and housing 220 may be made of non-stick material, thereby reducing the risk of conveying obstruction due to the adhesion of the adhesive strip 420 to the conveyor roller 210 or housing 220.

[0091] Reference Figure 7 , Figure 10 and Figure 11 As shown, it can be understood that the adhesive applicator 200 also includes a first linear driver 250 and a cutter 240. The housing 220 is provided with a cavity 222. Both the cavity 222 and the conveying channel 221 are open to the clamping mechanism 100. The first linear driver 250 is connected to the cutter 240 in a transmission manner, driving the cutter 240 to enter and exit the cavity 222 to cut the adhesive strip 420 that has passed through the conveying channel 221 and is attached to the battery cell 410.

[0092] Reference Figure 7 , Figure 10 and Figure 11 As shown, after the adhesive strip 420 is attached to the battery cell 410 according to the preset trajectory, that is, after the adhesive application is completed, the first linear driver 250 can drive the cutter 240 to extend out of the cavity 222, so that the cutter 240 cuts the adhesive strip 420 that has passed out of the conveying channel 221 and is attached to the battery cell 410, thus realizing the segmentation of the adhesive strip 420 and the application of adhesive to the edge of the battery cell 410.

[0093] Reference Figure 7 , Figure 10 and Figure 11 As shown, it can be understood that the adhesive applicator 200 also includes a second linear driver 230, which is connected to one of the conveyor rollers 210 to drive the conveyor roller 210 closer to or further away from the other conveyor rollers 210.

[0094] Reference Figure 7 , Figure 10 and Figure 11 As shown, when the adhesive applicator 200 is not applying adhesive, the second linear driver 230 can drive the conveyor roller 210 connected to it to move away from and then closer to the other conveyor rollers 210, thereby lengthening a section of adhesive strip 420 for later use. This can effectively avoid the problem of untimely delivery of adhesive strip 420 during the adhesive application process.

[0095] Reference Figure 7 , Figure 10 and Figure 11 As shown, it can be understood that the adhesive applicator 200 also includes a third linear actuator 260 and a pressure block 270. The upper end of the conveying channel 221 is connected to a first notch. The third linear actuator 260 is connected to the pressure block 270 to drive the pressure block 270 in and out of the first notch.

[0096] Reference Figure 7 , Figure 10 and Figure 11 As shown, when the adhesive applicator 200 is applying adhesive, the third linear driver 260 can drive the pressure block 270 to exit the first notch and separate from the adhesive strip 420 in the conveying channel 221, thereby eliminating the obstruction caused by the pressure block 270 to the conveying of the adhesive strip 420, so as to ensure that the adhesive strip 420 can apply adhesive to the battery cell 410 at a preset conveying speed.

[0097] Reference Figure 7 , Figure 10 and Figure 11 As shown, when the adhesive applicator 200 finishes applying the adhesive or needs to cut the adhesive strip 420, the third linear actuator 260 can drive the pressure block 270 into the first notch and abut against the adhesive strip 420 in the conveying channel 221 to restrict the movement of the adhesive strip 420.

[0098] It should be noted that the first linear actuator 250, the second linear actuator 230, and the third linear actuator 260 can all be linear drive mechanisms such as pneumatic actuators, hydraulic actuators, and electric actuators.

[0099] Reference Figure 7 , Figure 10 and Figure 11 As shown, it is understood that the adhesive application equipment for the battery cell also includes a third detection mechanism 530 connected to the adhesive application mechanism 200. The third detection mechanism 530 is configured to detect the adhesion of the adhesive strip 420 to the battery cell 410.

[0100] Reference Figure 7 , Figure 10 and Figure 11 As shown, the third detection mechanism 530 can be a color mark sensor, which determines whether the adhesive strip 420 is attached to the battery cell 410 by the color contrast change between the adhesive strip 420 and the battery cell 410.

[0101] Reference Figure 7 , Figure 10 and Figure 11 As shown, when the third testing agency 530 detects that the adhesive strip 420 is not attached to the cell 410, it can send a prompt message to the user so that the adhesive application to the cell 410 can be adjusted or repeated in a timely manner to improve the production quality of the battery.

[0102] Reference Figure 7 , Figure 10 and Figure 11 As shown, it should be noted that the testing principle and structure of the third testing agency 530 are conventional technical means in this field, and will not be elaborated here.
