Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, and in particular to an integrated machine for applying adhesive and peeling film. Background Technology

[0002] In the assembly of prismatic battery cells, double-sided adhesive tape is typically applied to their sidewalls to ensure a secure connection between adjacent cells. This tape usually comes with a release liner, which must be peeled off after application to allow for subsequent stacking and welding processes. Currently, tape application relies primarily on traditional tape-applying equipment, which has limited freedom of movement, supporting only horizontal and vertical motion and unable to directly apply tape to the sidewalls of vertically positioned cells. Therefore, in actual production, the cells must first be flipped to a horizontal position for tape application, and then flipped back to a vertical position after tape application and film removal to meet subsequent process layout requirements. This repeated flipping operation not only increases the number of process steps and reduces production efficiency but also increases equipment complexity and manufacturing costs. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an integrated adhesive application and film removal machine that can apply adhesive and remove film from the side wall of a vertically oriented battery cell with high processing efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide an integrated adhesive application and film removal machine, comprising:

[0005] The workbench is equipped with adhesive application and film removal stations.

[0006] A rotary table is rotatably mounted on the workbench and has at least one openable gripper assembly. The gripper assembly is used to hold the battery cell and keep it in a vertical position. The battery cell has an adhesive surface that is perpendicular to the horizontal plane. The rotary table can drive the gripper assembly to switch between the adhesive application station and the film peeling station.

[0007] An adhesive applicator is provided on the adhesive applicator station. The adhesive applicator includes an adhesive supply table, an adhesive applicator head, and a first drive assembly. The adhesive supply table is arranged perpendicularly to the adhesive applicator head. The first drive assembly is connected to the adhesive applicator head and can drive the adhesive applicator head to rotate between the adhesive applicator head and the adhesive supply table to absorb and stick the tape on the adhesive supply table to the adhesive applicator head.

[0008] A film-peeling mechanism is provided at the film-peeling station and is used to peel off the release film from the surface of the adhesive tape located on the adhesive surface.

[0009] Furthermore, the film-tearing mechanism includes a first drive module, a second drive module, and an openable film-tearing clamp. The first drive module is detachably and vertically mounted on the worktable, the second drive module is detachably and inclinedly mounted on the output end of the first drive module, and the film-tearing clamp is vertically arranged and detachably connected to the output end of the second drive module. The first drive module is used to drive the film-tearing clamp to move up and down, and the second drive module is used to drive the film-tearing clamp to move obliquely.

[0010] Furthermore, the film-tearing clamp includes a first clamping member and a second clamping member arranged opposite to each other and openable and closable. The first clamping member and the second clamping member are respectively provided with a connecting part and a clamping part. When the two clamping parts abut, there is a gap between the two connecting parts, and an air blowing structure is provided in the gap.

[0011] Furthermore, the workbench is also provided with a loading station and a unloading station. The loading station, adhesive application station, film removal station and unloading station are arranged in a ring. There are four gripper assemblies arranged around the circumference of the rotary table and correspond one-to-one with the loading station, adhesive application station, film removal station and unloading station. The rotary table can drive the four gripper assemblies to switch synchronously between different stations.

[0012] Furthermore, a vision inspection component is detachably provided on the unloading station, which is used to detect the adhesive application status of the battery cell as the gripper assembly switches to the unloading station.

[0013] Further, the first driving assembly includes a trajectory control plate, a first linkage structure, and a first driving member. The trajectory control plate is provided with a first guide groove, which includes a first guide segment, a second guide segment, and a third guide segment connected in sequence. One end of the first linkage structure is connected to the adhesive applicator head, and the other end is movably inserted into the first guide groove. The output end of the first driving member rotatably passes through the trajectory control plate and is connected to the first linkage structure, for driving the first linkage structure to move along the first guide groove. When the first linkage structure moves along the first guide segment, it can drive the adhesive applicator head to move vertically to absorb the adhesive tape. When the first linkage structure moves along the second guide segment, it can drive the adhesive applicator head to rotate to align with the adhesive surface or the adhesive supply table. When the first linkage structure moves along the third guide segment, it can drive the adhesive applicator head to move horizontally to apply adhesive to the adhesive surface.

[0014] Furthermore, both the first guide segment and the third guide segment are straight segments, and their extension directions are perpendicular to each other. The second guide segment is an arc transition segment connecting the first guide segment and the third guide segment.

[0015] Furthermore, the output end of the first driving member is provided with a second connecting rod structure, the second connecting rod structure is provided with a second guide groove, and the first connecting rod structure is provided with a connecting shaft that is slidably inserted into the second guide groove and the first guide groove in sequence; when the first driving member is working, the second connecting rod structure rotates, causing the connecting shaft to drive the first connecting rod structure to move along the second guide groove and the first guide groove.

[0016] Furthermore, the trajectory control board is rotatably provided with a rotating seat, and the rotating seat is provided with a sliding groove. The first connecting rod structure is slidably disposed on the sliding groove, and the rotation center of the rotating seat and the rotation center of the second connecting rod structure are located on the angle bisector of the right angle formed by the first guide segment and the third guide segment. When the connecting shaft moves along the second guide segment, the rotating seat rotates around its own axis and drives the first connecting rod structure to rotate synchronously.

[0017] Furthermore, the center point of the rotating seat is located at the intersection of the extension lines of the first guide segment and the third guide segment, and the distance between the rotation center of the rotating seat and the rotation center of the second connecting rod structure is equal to the length of the first guide segment and the third guide segment.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. In this utility model, the worktable is equipped with an adhesive application mechanism and a film removal mechanism, as well as a rotatable rotary table. The rotary table has at least one openable and closable gripper assembly for holding the battery cell and maintaining its vertical position. The rotary table can drive the gripper assembly to switch between the adhesive application station and the film removal station. The adhesive application mechanism includes an adhesive supply table, an adhesive application head, and a first drive assembly. The adhesive supply table is arranged perpendicularly to the adhesive application surface. The first drive assembly is connected to the adhesive application head and can drive the adhesive application head to rotate between the adhesive application surface and the adhesive supply table to absorb and adhere the tape on the adhesive supply table to the adhesive application surface. This integrated design breaks through the limitations of traditional equipment on the adhesive application and film removal directions, allowing the battery cell to directly complete the adhesive application and film removal operations in a vertical position. This avoids the problems of process complexity, reduced production efficiency, and increased equipment costs caused by repeated flipping, significantly improving the automation level and production cycle of adhesive application and film removal.

[0020] 2. In this utility model, the film-tearing mechanism includes a film-tearing clamp, which includes a first clamping member and a second clamping member arranged opposite to each other and openable and closable. The first clamping member and the second clamping member are respectively provided with a connecting part and a clamping part. When the two clamping parts abut, there is a gap between the two connecting parts, and an air-blowing structure is provided in the gap. This design effectively removes release film fragments remaining in the clamp through the air-blowing structure, preventing film adhesion failure or poor adhesive application caused by film adhesion, improving the stability and reliability of film tearing, while enhancing the self-cleaning ability of the equipment and reducing the maintenance frequency.

[0021] 3. In this utility model, the first driving assembly includes a trajectory control plate, a first linkage structure, and a first driving member. The trajectory control plate is provided with a first guide groove, which includes a first guide segment, a second guide segment, and a third guide segment connected in sequence. One end of the first linkage structure is connected to the adhesive applicator, and the other end is movably inserted into the first guide groove. The output end of the first driving member rotatably passes through the trajectory control plate and is connected to the first linkage structure to drive the first linkage structure to move along the first guide groove. When the first linkage structure moves along the first guide segment, it can drive the adhesive applicator to move vertically to absorb the adhesive tape. When the first linkage structure moves along the second guide segment, it can drive the adhesive applicator to rotate to align with the adhesive surface or the adhesive supply table. When the first linkage structure moves along the third guide segment, it can drive the adhesive applicator to move horizontally to apply adhesive to the adhesive surface. This design utilizes a three-segment continuous guide groove mechanical guidance structure, requiring only a single primary drive component to control the adhesive application head, completing the entire process of adhesive pickup, steering, and application. This significantly simplifies the overall mechanism structure and reduces equipment manufacturing and maintenance costs. Furthermore, the purely mechanical guidance method avoids complex servo control, improving the stability and repeatability of the equipment's operation. Attached Figure Description

[0035] like Figures 1 to 6 As shown, in this embodiment, an adhesive application and film removal integrated machine includes:

[0036] Workbench 100, which is equipped with an adhesive application station and a film removal station;

[0037] A rotary table 200 is rotatably mounted on a worktable 100 and is provided with at least one openable gripper assembly 210. The gripper assembly 210 is used to hold the battery cell 600 and keep it in a vertical position. The battery cell 600 has an adhesive surface 610 that is perpendicular to the horizontal plane. The rotary table 200 can drive the gripper assembly 210 to switch between an adhesive application station and a film peeling station.

[0038] The adhesive applicator 300 is located at the adhesive applicator station. The adhesive applicator 300 includes an adhesive supply table 311, an adhesive applicator head 321, and a first drive assembly 330. The adhesive supply table 311 is arranged perpendicularly to the adhesive applicator surface 610. The first drive assembly 330 is connected to the adhesive applicator head 321 and can drive the adhesive applicator head 321 to rotate between the adhesive applicator surface 610 and the adhesive supply table 311 to absorb and stick the adhesive tape on the adhesive supply table 311 to the adhesive applicator surface 610.

[0039] The film-peeling mechanism 400, located at the film-peeling station, is used to peel the release film from the adhesive tape surface on the adhesive-applying surface 610. This integrated design breaks through the limitations of traditional equipment on the direction of adhesive application and film peeling, allowing the battery cell 600 to directly complete the adhesive application and film peeling operations in a vertical position. This avoids the problems of process complexity, reduced production efficiency, and increased equipment costs caused by repeated flipping, and significantly improves the automation level and production cycle of adhesive application and film peeling.

[0040] like Figures 1 to 6As shown, in this embodiment, the adhesive application and release film peeling machine mainly consists of a worktable 100, a rotary table 200, an adhesive application mechanism 300, a release film peeling mechanism 400, and a vision inspection component 500. It is used to apply adhesive and peel the release film from vertically oriented square batteries. The battery cell 600 has an adhesive application surface 610 perpendicular to the horizontal plane. The worktable 100 serves as the main support for the equipment, housing and supporting the other functional modules. The rotary table 200 is rotatably mounted on the worktable 100 and has at least one openable gripper assembly 210 for holding the battery cell 600 and maintaining its vertical orientation. Rotation allows the gripper assembly 210 to switch between different workstations. The adhesive application mechanism 300 and the release film peeling mechanism 400 are respectively positioned at corresponding workstations to perform continuous adhesive application and release film peeling operations on the adhesive application surface 610 of the battery cell 600. The vision inspection component 500 automatically inspects the adhesive application quality before unloading, ensuring product consistency and process reliability.

[0041] In this embodiment, the workbench 100 has a stepped structure, consisting of a first placement platform 110 and a second placement platform 120 with a height difference. The first placement platform 110 has a greater horizontal height than the second placement platform 120, and it has a loading station, a film-removing station, and a unloading station. The second placement platform 120 has an adhesive-applying station, and these stations are arranged in a ring. This design rationally allocates the functional areas of the equipment through a stepped layout, effectively isolating and orderly connecting different processes in space. This not only improves the overall structural compactness but also enhances the safety and ease of maintenance of the equipment.

[0042] In this embodiment, the rotary table 200 is rotatably mounted on the first placement platform 110, and four gripper assemblies 210 are evenly arranged circumferentially on it. Each gripper assembly 210 can be opened and closed to hold the battery cell 600 and keep it in a vertical position, thereby ensuring the stability and reliability of subsequent adhesive application and film removal operations.

[0043] In this embodiment, the four gripper assemblies 210 correspond one-to-one with the loading station, adhesive application station, film peeling station, and unloading station, respectively. The rotary table 200 drives the four gripper assemblies 210 to switch synchronously between the stations, thereby realizing a continuous and periodic production process. This design significantly improves the automation level and production cycle of the adhesive application and film peeling machine through multi-station collaborative cooperation. The one-to-one correspondence between the gripper assemblies 210 and the stations facilitates positioning and action matching by the control system, ensuring seamless connection between each process. In addition, the method of using the rotary table 200 to drive multiple gripper assemblies 210 to switch synchronously not only simplifies the transmission structure but also allows the actuators on each station to operate independently and synchronously, avoiding efficiency losses caused by action conflicts or waiting, and further improving overall work efficiency and equipment operation stability.

[0044] In this embodiment, each gripper assembly 210 includes a first gripper cylinder 211 and a first chuck 212 and a second chuck 213 arranged opposite to each other. The first chuck 212 and the second chuck 213 have the same structure, both being L-shaped plate structures, and are detachably connected to the two output ends of the first gripper cylinder 211, respectively. They can open and close under the drive of the cylinder, thereby clamping and releasing the battery cell 600. This design is not only simple in structure and reliable in operation, but also, through the layout of the L-shaped chucks, can better conform to the contour of the battery cell 600, improving clamping stability, especially suitable for clamping requirements when the battery cell 600 is kept in a vertical position. In addition, the detachable connection between the chucks and the cylinder makes it easy to replace chucks of different sizes or shapes according to actual production needs to adapt to changes in the specifications of the battery cell 600, and has good versatility and adaptability.

[0045] In this embodiment, the first clamp 212 and the second clamp 213 each have a buffer on the side that contacts the surface of the battery cell 600. Preferably, the buffer is a rubber pad or other elastic material to avoid damage to the surface of the battery cell 600 during clamping, thereby improving product yield and equipment safety.

[0046] In this embodiment, a support plate 220 is also provided below the gripper assembly 210. The support plate 220 extends horizontally to the area below the first gripper 212 and the second gripper 213, and is used to temporarily support the battery cell 600 when the gripper assembly 210 is in the released state (gripper open). This design facilitates the gripper holding the battery cell 600 and prevents the battery cell 600 from falling or tilting due to gravity during the gripping and releasing process, thereby improving the safety and operational stability of the equipment.

[0047] Preferably, in this embodiment, a positioning plate 230 is vertically disposed on the support plate 220. The positioning plate 230 abuts against the side of the battery cell 600 facing away from the adhesive surface 610, thereby limiting and calibrating the position of the battery cell 600 during the clamping process. This design ensures that the battery cell 600 is always in a preset aligned position before and after clamping, thereby improving the accuracy and consistency of subsequent processes such as adhesive application and film removal.

[0048] In this embodiment, the adhesive applicator 300 is detachably mounted on the second placement platform 120, and includes an adhesive supply component 310, an adhesive applicator 320, a first drive component 330, and a support bracket 340. The adhesive supply component 310 carries and releases the double-sided adhesive tape, ensuring stable delivery of the tape to the applicator area. The adhesive applicator 320 adsorbs and positions the tape, accurately attaching it to the adhesive surface 610 on the sidewall of the battery cell 600. The first drive component 330 is connected to the adhesive applicator 320, enabling it to perform combined vertical and horizontal movements to complete the adsorption, turning, and applicating actions of the tape. The support bracket 340 serves as a support structure for mounting the first drive component 330 and the adhesive applicator 320, ensuring the relative positional accuracy and operational stability of the components.

[0049] In this embodiment, the adhesive supply assembly 310 is horizontally arranged on the second placement platform 120 and extends away from the first placement platform 110. The adhesive supply assembly 310 includes a horizontally arranged rectangular adhesive supply platform 311, which is perpendicular to the adhesive application surface 610. This platform is used to support and position the double-sided adhesive tape roll or pre-cut film to be applied, ensuring it is in a suitable position for the adhesive application assembly 320 to absorb. The working principle of the adhesive supply assembly 310 and other related structures are readily apparent in conventional designs in the prior art and will not be described further here.

[0050] In this embodiment, a third drive module 700 and a fourth drive module 710 are arranged horizontally and vertically intersecting below the glue supply assembly 310. The third drive module 700 drives the glue supply platform 311 to move along the X-axis, and the fourth drive module 710 drives it to move along the Y-axis. Working together, they enable precise positioning and adjustment of the glue supply platform 311 on the horizontal plane. This design allows users to flexibly adjust the design according to changes in the battery cell 600 specifications, glue application position, and process parameters, thereby improving glue application accuracy and equipment adaptability.

[0051] In this embodiment, the support bracket 340 is vertically disposed on the adjacent side of the adhesive supply component 310. One end of the support bracket 340 is detachably fixed to the second placement platform 120 by fasteners, and the other end extends vertically away from the second placement platform 120. The first drive component 330 is disposed on the extended end of the support bracket 340 and is used to control the adhesive application component 320 to complete the multi-stage composite action.

[0052] Preferably, a fifth drive module 720 is provided between the first drive assembly 330 and the support bracket 340. One side of the fifth drive module 720 is detachably fixed to the support bracket 340 by fasteners, and the other side is detachably connected to the trajectory control plate 331 to drive the trajectory control plate 331 to move up and down in the vertical direction. This design realizes the function of adjusting the height position of the trajectory control plate 331 through the fifth drive module 720, thereby driving the overall vertical position adjustment of the adhesive application assembly 320. This structural feature significantly improves the adaptability of the equipment to battery cells 600 of different height specifications, allowing the same adhesive application mechanism 300 to adapt to changes in the height of the battery cells 600 without changing parts, enhancing the flexibility and versatility of the equipment in practical applications.

[0053] In this embodiment, the first drive assembly 330 includes a trajectory control plate 331, a first linkage structure 332, and a first drive member 333. The trajectory control plate 331 is provided with a first guide groove 335, which includes a first guide segment 335a, a second guide segment 335b, and a third guide segment 335c connected in sequence to form a continuous guide path with a specific trajectory.

[0054] In this embodiment, one end of the first linkage structure 332 is connected to the adhesive applicator 321, and the other end is movably inserted into the first guide groove 335. The output end of the first drive member 333 rotatably passes through the trajectory control plate 331 and is connected to the first linkage structure 332, which is used to drive the first linkage structure 332 to move along the first guide groove 335. When the first linkage structure 332 moves along the first guide section 335a, it can drive the adhesive applicator 321 to move in the vertical direction to absorb the adhesive tape. When the first linkage structure 332 moves along the second guide section 335b, it can drive the adhesive applicator 321 to rotate to align with the adhesive surface 610 or the glue supply table 311. When the first linkage structure 332 moves along the third guide section 335c, it can drive the adhesive applicator 321 to move in the horizontal direction to apply adhesive to the adhesive surface 610. This design utilizes a three-segment continuous guide groove mechanical guidance structure, requiring only a single first drive component 333 to control the adhesive application head 321 to complete the entire process of adhesive picking, turning, and application. This significantly simplifies the overall structure of the mechanism and reduces equipment manufacturing and maintenance costs. Furthermore, the purely mechanical guidance method avoids complex servo control, improving the stability and repeatability of the equipment operation.

[0055] In this embodiment, the first guide segment 335a and the third guide segment 335c are both straight segments, and their extension directions are perpendicular to each other. The second guide segment 335b is an arc transition segment connecting the first guide segment 335a and the second guide segment 335b, used to achieve a smooth transition in the movement direction of the adhesive applicator 321. This design not only ensures precise control of the rotation angle of the adhesive applicator 321, but also enhances the continuity of action and the stability of movement between each operation stage, avoiding vibration or positioning deviation caused by sudden changes in direction.

[0056] In this embodiment, a rotating seat 337 is rotatably provided on the trajectory control plate 331, and a sliding groove 337a is provided on the rotating seat 337. The first connecting rod structure 332 is slidably provided on the sliding groove 337a, thereby realizing relative movement with respect to the rotating seat 337, that is, adjustment of the degree of freedom in the X-axis direction and the Z-axis direction.

[0057] When the connecting shaft 332a moves along the second guide section 335b, the rotating seat 337 rotates around its own axis, driving the first connecting rod structure 332 to rotate synchronously, completing the attitude adjustment action and thus achieving a smooth turn from the vertical to the horizontal direction. This design eliminates the need for an additional independent rotary drive component, achieving the attitude change function of the adhesive applicator 321 through trajectory guidance and mechanical linkage. It not only boasts a compact structure and simple control logic but also effectively reduces the overall complexity and manufacturing and maintenance costs of the device, while improving the stability and repeatability of the equipment.

[0058] In this embodiment, the rotation center of the rotating seat 337 and the rotation center of the second connecting rod structure 336 are located on the angle bisector of the right angle formed by the first guide segment 335a and the third guide segment 335c. This design ensures that the rotation path of the adhesive applicator 321 has good symmetry and a more uniform force distribution during the transition from longitudinal (Z-axis) to lateral (X-axis) movement.

[0059] In this embodiment, the center point of the rotating seat 337 is located at the intersection of the extension lines of the first guide segment 335a and the third guide segment 335c, and the distance between the rotation center of the rotating seat 337 and the rotation center of the second linkage structure 336 is equal to the lengths of the first guide segment 335a and the third guide segment 335c. This design not only ensures the smoothness of the rotational movement but also effectively shortens the force arm length of the first linkage structure 332 and the second linkage structure 336, thereby reducing the bending moment and stress borne by the structure and improving the stability and reliability of the overall mechanical transmission. In addition, this design significantly reduces the volume occupied by the linkage mechanism in space, optimizes the overall layout of the equipment, and makes the adhesive application assembly 320 more compact.

[0060] In this embodiment, the trajectory control board 331 is further provided with a second sensor and a third sensor, which are electrically connected to the first drive unit 333 respectively, for realizing the limit detection and control of the movement stroke of the adhesive assembly 320. The second sensor is used to detect position changes of the second sensing part, and the third sensor is used to detect position changes of the third sensing part. When the second sensing part enters the sensing area of ​​the second sensor, the second sensor sends a feedback signal to the first drive unit 333, triggering the control system to execute a corresponding action switching or stop command, thereby preventing the first linkage structure 332 from overtravel within the first guide section 335a. Similarly, when the third sensing part enters the sensing area of ​​the third sensor, the third sensor also sends an electrical signal to the first drive unit 333, limiting its continued operation and preventing the first linkage structure 332 from overtraveling or overshooting within the third guide section 335c.

[0061] In this embodiment, the second sensing element is detachably disposed on the adjacent side of the end of the first guide section 335a, and its end is provided with a second U-shaped groove for the second sensing part to freely enter and exit, which is used to limit the movement stroke of the first connecting rod structure 332 in the Z-axis direction.

[0062] In this embodiment, a third U-shaped groove is provided at its end for the third sensing part to freely enter and exit, which is used to limit the stroke of the first connecting rod structure 332 in the X-axis direction.

[0063] Preferably, in this embodiment, both the second and third sensors are photoelectric switches. These switches offer advantages such as fast response speed, high detection accuracy, and strong anti-interference capabilities, effectively improving the stability of equipment operation and the reliability of the control system.

[0064] In this embodiment, the trajectory control board 331 is also provided with a first limiting member and a second limiting member, which are used to mechanically limit the movement of the first linkage structure 332 in the Z-axis direction and the X-axis direction to prevent overshoot or overrun caused by abnormal drive or failure of the control system.

[0065] In this embodiment, the first limiting member is detachably disposed on the adjacent side of the end of the first guide section 335a. When it abuts against the first limiting part on the first connecting rod structure 332, it can prevent the first connecting rod structure 332 from continuing to move in the original direction, thereby realizing its physical limiting function in the Z-axis direction. The second limiting member is detachably disposed on the adjacent side of the end of the third guide section 335c. When it contacts the second limiting part on the first connecting rod structure 332, it can restrict the first connecting rod structure 332 from continuing to move in the original direction, thereby realizing its mechanical limiting function in the X-axis direction. This design not only enhances the safety and stability of the adhesive application assembly 320 during operation, but also provides an additional mechanical protection mechanism in addition to the sensing control, forming a "sensing + mechanical" dual limiting protection system, further improving the reliability and risk resistance of the equipment operation. In addition, the limiting member adopts a detachable installation structure, which facilitates flexible adjustment of the limiting position or replacement of parts according to actual working conditions, improving the applicability and maintenance convenience of the equipment.

[0066] In this embodiment, the first connecting rod structure 332 is in the form of a strip guide rail and is slidably disposed in the sliding groove 337a on the rotating seat 337. One end of it is detachably connected to the protrusion on the adhesive head 321 by a fastener, and the other end extends away from the protrusion to form a free end.

[0067] In this embodiment, the free end of the first linkage structure 332 facing the trajectory control plate 331 is provided with a connecting shaft 332a. The connecting shaft 332a is slidably inserted into the second guide groove 336a and the first guide groove 335 in sequence to form a guiding fit. When the first driving member 333 works, it drives the second linkage structure 336 to rotate, so that the connecting shaft 332a drives the first linkage structure 332 to move along the second guide groove 336a and the first guide groove 335, so as to realize the composite motion of the first linkage structure 332 between the vertical direction (Z-axis) and the horizontal direction (X-axis), thereby driving the adhesive applicator 321 to complete multi-stage actions such as adhesive suction, turning and adhesive application. The entire process can complete complex path motion without additional driving mechanism, and has the advantages of compact structure, stable response and simple control logic.

[0068] In this embodiment, a mounting block is provided on the side of the extension end of the first link structure 332 away from the trajectory control plate 331. The mounting block is arranged along the length direction of the first link structure 332 and is used to fix components such as the second sensing part, the third sensing part, the first limiting part, and the second limiting part.

[0069] In this embodiment, the second and third sensing units are detachably and symmetrically disposed on both sides of the mounting block, extending in opposite directions to cooperate with the second and third sensing elements respectively disposed on the trajectory control plate 331. When the first linkage structure 332 moves along the first guide section 335a to its vertical limit position, the second sensing unit enters the second U-shaped groove of the second sensing element, triggering a sensing signal feedback to control the first drive unit 333 to stop or switch its movement direction; when the first linkage structure 332 moves along the third guide section 335c to its horizontal limit position, the third sensing unit enters the third U-shaped groove of the third sensing element, similarly triggering an electrical signal feedback to limit the adhesive applicator head 321 from continuing to advance, preventing overshoot or overtravel. This design, through the cooperation between the second and third sensing units and the second and third sensing elements, achieves precise position recognition and control of the adhesive applicator assembly 320 at different movement stages, improving the safety and control accuracy of equipment operation.

[0070] In this embodiment, the first limiting part and the second limiting part are fixedly and symmetrically disposed on both sides of the mounting block and extend in opposite directions, so as to form a mechanical limiting engagement with the first limiting member and the second limiting member correspondingly disposed on the trajectory control plate 331.

[0071] In this embodiment, the first driving member 333 is detachably mounted on the trajectory control plate 331. Its output end rotatably passes through the trajectory control plate 331 from the back and is connected to the first linkage structure 332. It is used to drive the first linkage structure 332 to move along the first guide groove 335 and sequentially complete composite actions such as longitudinal glue taking, rotation alignment and transverse glue application.

[0072] In this embodiment, a second linkage structure 336 is detachably provided on the output end of the first driving member 333. The second linkage structure 336 is a strip-shaped rod structure with a second guide groove 336a extending along its length. When the first driving member 333 is activated and drives the output end to rotate, the second linkage structure 336 rotates synchronously. At this time, the second guide groove 336a on the second linkage structure 336 guides the connecting shaft 332a to move along a set path through sliding engagement with the connecting shaft 332a, and further drives the first linkage structure 332 to move along the first guide groove 335 on the trajectory control plate 331. Through this mechanical linkage structure, the adhesive application assembly 320 can complete multiple stages of actions such as adhesive suction, turning and adhesive application in sequence according to a predetermined trajectory under the control of a single driving source, realizing the efficient integration of multi-degree-of-freedom composite motion. This design is not only compact and stable in response, but also significantly simplifies the control system logic and improves the repeatability and automation level of the equipment operation.

[0073] In this embodiment, the adhesive applicator 320 includes an adhesive applicator head 321 and a first air supply structure (not shown in the figure). The adhesive applicator head 321 is used to absorb adhesive tape and can perform longitudinal movement, rotation and horizontal application under the drive of the first drive assembly 330, thereby transferring the adhesive tape from the adhesive supply platform 311 to the adhesive application surface 610 on the side wall of the battery cell 600.

[0074] In this embodiment, the first air supply structure is connected to the adsorption channel inside the adsorption block 321b in the adhesive applicator 321. The adsorption and release of the adhesive tape are achieved by controlling the opening and closing of the air path. Specifically, when the adsorption block 321b moves to contact the adhesive supply platform 311, the vacuum adsorption function is activated to grab the adhesive tape; when the adhesive applicator 321 moves to contact the adhesive surface 610 of the battery cell 600, the vacuum is turned off and the adhesive tape is released, so that it is accurately pasted on the adhesive surface 610 of the battery cell 600.

[0075] In this embodiment, the adhesive applicator 321 includes a rectangular connecting block 321a and an adsorption block 321b arranged vertically. One side of the connecting block 321a is detachably connected to the first connecting rod structure 332 for easy installation and replacement; the other side is connected to the adsorption block 321b via four matrix-distributed elastic pillars 322, allowing the adsorption block 321b to float vertically relative to the connecting block 321a within a certain range. This design not only facilitates flexible contact with the battery cell 600 during the adhesive application process but also allows the first sensor to determine the adhesive adsorption status and application position, thereby improving the control system's real-time monitoring capability of the adhesive application process.

[0076] In this embodiment, the connecting block 321a has a vertically arranged protrusion and a rectangular notch adjacent to the protrusion and penetrating through the connecting block 321a. A first sensor is detachably mounted on the protrusion. The first sensor is aligned with the notch and has a first U-shaped groove for the first sensing part to freely enter and exit, used to detect the position change or action state of the adsorption block 321b. Preferably, the first sensor is a photoelectric switch.

[0077] In this embodiment, the adsorption block 321b is detachably provided with a vertically arranged first sensing part. The first sensing part can enter the first U-shaped groove when the adsorption block 321b floats up and down, thereby triggering signal feedback. The control system determines whether the adsorption block 321b has contacted the adhesive surface 610 of the tape or the battery cell 600 based on the feedback signal, and controls the first driving member 333 to switch directions or other actions accordingly. Specifically, when the adhesive applicator 321 is in the process of picking up or applying adhesive, the adsorption block 321b is subjected to a reverse force due to contact with the surface of the tape or the battery cell 600, causing the elastic column 322 to undergo compression deformation, which drives the first sensing part to move upward and enter the first U-shaped groove. At this time, the first sensing member detects that the sensing part has entered the sensing area and immediately sends a trigger signal to the control system, thereby controlling the first driving member 333 to rotate forward or backward to execute subsequent operations and realize automated closed-loop control.

[0078] In this embodiment, the film-peeling mechanism 400 is detachably mounted on the first placement platform 110. It is used to automatically peel off the release film of the adhesive tape attached to the surface of the vertically positioned battery cell 600 after the adhesive application is completed. This provides a clean adhesive surface with the release film removed for subsequent assembly, stacking, or packaging processes, ensuring the continuity of the process and the quality of product assembly.

[0079] In this embodiment, the film-peeling mechanism 400 includes a first drive module 410, a second drive module 420, and an openable and closable film-peeling clamp 430. The first drive module 410 is vertically arranged and detachably mounted on the first placement platform 110 via fasteners or a quick-change interface, used to drive the film-peeling clamp 430 to move vertically up and down. The second drive module 420 is detachably mounted at an angle on the output end of the first drive module 410, and its output end is connected to the film-peeling clamp 430, used to drive the film-peeling clamp 430 to move obliquely at a set angle. The film-peeling clamp 430 is vertically arranged, detachably connected to the output end of the second drive module 420, and has an opening and closing function, capable of stably gripping and peeling the release film from the surface of the battery cell 600. This design enables the film-peeling chuck 430 to descend vertically to a preset position under the drive of the first drive module 410, accurately gripping the release film on the adhesive tape on the surface of the battery cell 600; subsequently, driven by the second drive module 420, the film-peeling chuck 430 moves along an oblique path at a set angle, achieving a smooth and efficient peeling operation of the release film.

[0080] In this embodiment, the set angle is the angle between the first drive module 410 and the second drive module 420, preferably 30° to 60°. This design can effectively simulate the action trajectory of manual film tearing, reduce the instantaneous tension generated during the film tearing process, thereby avoiding adverse phenomena such as accidental tearing of tape, misalignment, or damage to the surface of the battery cell 600 caused by concentrated force, and significantly improve the stability and success rate of the film tearing process.

[0081] In this embodiment, the film-tearing clamp 430 includes a first clamping member 431 and a second clamping member 432 arranged opposite to each other and openable and closable. Each has a connecting portion 431a for installation and fixing, and a clamping portion 431b for clamping the release film. When the two clamping portions 431b abut against each other and close, a certain gap 431c remains between their corresponding connecting portions 431a. An air-blowing structure 440 is provided within this gap 431c. This design allows the air-blowing structure 440 to spray airflow into the clamping area after the clamp completes the film-tearing action or during the resetting process, effectively removing release film fragments or dust remaining on the surface of the clamping portion 431b. This prevents problems such as clamping failure, incomplete film tearing, or accidental tape tearing caused by film residue, significantly improving the stability and reliability of the film-tearing process, while also enhancing the equipment's self-cleaning capability and reducing maintenance frequency.

[0082] In this embodiment, the film-tearing chuck 430 includes a second gripper cylinder 450. This cylinder serves as the actuator for the gripping action, and its two output ends are respectively connected to the connecting portion 431a of the first gripper 431 and the second gripper 432. Driven by the second gripper cylinder 450, the two grippers can move synchronously relative to each other, realizing the opening and closing action of the gripping portion 431b, thereby completing the stable gripping and release of the release film on the surface of the battery cell 600.

[0083] In this embodiment, the connecting part 431a is arranged vertically, with its upper end connected to the output end of the second gripper cylinder 450 and its lower end vertically connected to the horizontally arranged clamping part 431b, forming a stable mechanical structure. The thickness of the connecting part 431a is less than the thickness of the clamping part 431b, forming a gap 431c space between them to accommodate the air blowing structure 440.

[0084] In this embodiment, the film-tearing mechanism 400 also includes a second air supply structure (not shown in the figure) connected to the air-blowing structure 440, which provides a stable air source for the air-blowing structure 440. This air supply structure can be integrated inside the equipment or connected through an external air circuit, and can be linked with the chuck movement through a control system to automatically perform a cleaning operation after each film tearing, thereby improving the automation level and maintenance convenience of the equipment.

[0085] In this embodiment, the first placement platform 110 is also provided with a waste outlet 111, which is located directly below the film-tearing clamp 430 and extends through the upper surface of the first placement platform 110, for receiving release film fragments peeled off by the film-tearing clamp 430.

[0086] Preferably, in this embodiment, the first, second, third, fourth, and fifth drive modules 720 are all linear drive modules.

[0087] In this embodiment, a vision inspection component 500 is detachably installed on the unloading station. This vision inspection component 500 is used to inspect the adhesive application status of the battery cell 600 as it is switched to the unloading station by the gripper assembly 210. The inspection includes key process parameters such as tape position, bonding angle, and whether there is any offset or wrinkles, thereby providing a basis for subsequent classification and processing of the battery cell 600 (such as the transfer of qualified products or the rejection of unqualified products).

[0088] In this embodiment, the vision inspection component 500 includes an industrial camera 510 and a light source ring structure 520 detachably mounted on the first placement platform 110. The industrial camera 510 and the light source ring structure 520 work together to quickly acquire high-definition images of the adhesive application area of ​​the battery cell 600 under uniform illumination. The built-in image processing algorithm intelligently analyzes the image information to automatically identify whether the adhesive application quality meets the set process standards. This design enables online quality monitoring of the adhesive application process, which not only helps improve product yield and process consistency but also allows the inspection results to be fed back to the control system in real time for functions such as triggering alarms, controlling the rejection mechanism, or adjusting adhesive application parameters, further improving the automation level of the equipment and the controllability of the production process.
