[0002] In the battery cell manufacturing process, the adhesive application process is a crucial step in ensuring the insulation performance and safety of the cells. Insulating tape needs to be applied to specific locations on the cells. Most existing adhesive application equipment uses a single-reel feeding method. When multiple cells need to be adhesive-applied on the production line, the equipment must complete the adhesive application process for each cell individually, resulting in low overall production efficiency. Furthermore, during the process of the tape being pulled from the reel and applied to the cell surface, the mismatch between the feeding speed and the adhesive application speed often leads to loose or overstretched tape, causing quality problems such as wrinkles, bubbles, or poor adhesion after application.

[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0034] Reference Figure 1-4 An adhesive application mechanism includes: a feeding assembly 100, including multiple parallel trays 110 for supplying multiple adhesive tapes 120 and maintaining an independent feeding path for each tape 120; a pulling assembly 200, including a clamping part 210 for clamping each tape 120 and simultaneously pulling the front end of each tape 120 to the corresponding adhesive application position on the battery cell 700; and an adhesive application assembly 300, including a pressing part 321 and a cutting part 322, wherein the pressing part 321 simultaneously presses each tape 120 onto the surface of the corresponding battery cell 700, and the cutting part 322 cuts the applied tape 120; wherein the feeding assembly 100, the pulling assembly 200, and the adhesive application assembly 300 cooperate with each other to form multiple parallel adhesive application paths, realizing simultaneous adhesive application to multiple battery cells 700.

[0035] Understandably, in practical applications, multiple trays 110 on the feeding assembly 100 are loaded with different rolls of tape 120. For example, on a power battery module production line, two trays 110 can supply two rolls of insulating tape 120 at the same time. Each tray 110 controls the release tension of the tape 120 through the unwinding mechanism to ensure the stability of each tape 120 during the feeding process.

[0036] When two battery cells 700 need to be glued at the same time on the production line, the clamping part 210 of the pulling component 200 drives the first clamping plate 2112 to approach the second clamping plate 2113 through the clamping cylinder 2111, clamping the two tapes 120 in the corresponding clamping positions respectively. Then the first driving component 212 drives the entire clamping part 210 to move from the feeding position to the glue application position above the battery cell 700. During this process, each tape 120 remains independent of each other.

[0037] Upon reaching the adhesive application position, the second drive unit 310 of the adhesive application assembly 300 first drives the retainer 320 to move to the first position, bringing the pressure roller 3211 and the cutter 3221 close to the surface of the battery cell 700. Then, the pressure cylinder 3212 drives the pressure roller 3211 to move downward to the second position, pressing the two tapes 120 onto the surfaces of the two battery cells 700 simultaneously. After pressing is completed, the cutter cylinder 3222 drives the cutter 3221 to move to the third position, cutting the two applied tapes 120 at once, thus completing one adhesive application cycle.

[0038] Throughout the process, the feeding component 100 maintains a stable tension on the tape 120, the pulling component 200 accurately controls the conveying length of the tape 120, and the adhesive application component 300 performs pressing and cutting actions. The coordinated operation of the three components enables efficient and synchronous adhesive application to multiple battery cells 700.

[0039] It should be noted that the tape used in this case is preferably a stop adhesive.

[0040] In some embodiments, refer to Figure 4 , 8 It also includes a detection component 400, which is disposed on the adhesive application path between the feeding component 100 and the pulling component 200, and is used to detect the remaining amount of adhesive tape 120. Specifically, the detection component 400 includes a sensor 410, and the adhesive tape 120 is provided with a preset position mark. The sensor 410 is used to detect the mark to determine the remaining amount of adhesive tape 120. When the mark is detected, the adhesive application mechanism stops the adhesive application operation, and the pulling component 200 maintains the clamping state of the adhesive tape 120.

[0041] Understandably, the detection component 400 is installed on the conveying path of the tape 120 between the feeding component 100 and the pulling component 200. For example, during the process of feeding the tape 120 from the two trays 110 to the pulling component 200, each tape 120 will pass through the detection area of ​​the corresponding sensor 410. The tape manufacturer has pre-set reflective marks or color marks at the end of the tape 120. When the tape 120 on the first tray 110 is about to run out, the mark on its tape 120 will be detected by the sensor 410.

[0042] After the sensor 410 detects the identification signal, the control system immediately stops the adhesive application operation of the entire adhesive application mechanism. At this time, the clamping part 210 of the pulling component 200 still holds the two tapes 120 in a clamping state to prevent the tapes 120 from retracting or loosening. The operator can replace the tape 120 roll of the first material tray 110 while the equipment is stopped. After the replacement is completed, the front end of the new tape 120 is passed through the detection component 400 area and sent to the clamping position of the clamping part 210.

[0043] Since there is still some tape 120 remaining in the second tray 110 and it is stably held by the clamping part 210, it is only necessary to adjust the position of the first new tape 120 to align it with the second tape 120, so that the two tapes 120 can be used simultaneously for subsequent adhesive application. This design avoids the generation of waste products due to the exhaustion of a single tape 120, while ensuring the continuity and consistency of multi-path adhesive application.

[0044] Furthermore, referring to Figure 8 The detection component 400 uses a through-beam sensor 410, with its transmitter and receiver positioned on opposite sides of the tape 120 transmission path. The tape 120 passes through the middle. For example, in a tape application system with two trays 110, the tape manufacturer attaches an opaque label to the end of the tape 120. This predetermined length ensures that at least one complete loop of tape 120 remains on the tray 110.

[0045] When the tape 120 of the first tray 110 passes the through-beam sensor 410, the label will block the light transmission. The receiving end of the sensor 410 detects the interruption of the light signal and immediately sends a signal to the control system. At this time, there is still about one ring of tape 120 on the tray 110 for buffering. After the clamping part 210 of the pulling assembly 200 receives the detection signal, the clamping cylinder 2111 increases the output pressure, which increases the clamping force between the first clamping plate 2112 and the second clamping plate 2113, ensuring that the two tapes 120 are firmly clamped and will not fall off.

[0046] Operators can directly connect the starting end of the new tape 120 to the end of the old tape 120 at the material tray 110 by gluing or overlapping. Since a ring of tape 120 is retained on the material tray 110, there is enough operating space and time during the connection process. After the connection is completed, the label on the old tape 120 is removed. After the system detects that the light signal has returned to normal, the tape application operation is automatically resumed. Throughout the process, the second tape 120 is always in a normal feeding state, realizing continuous production without stopping the machine to change materials.

[0047] Reference Figure 1-4It also includes a buffer component 500, disposed between the detection component 400 and the pulling component 200, for storing and releasing tape 120 of a predetermined length. It is understood that the buffer component 500 pre-stores a certain length of tape 120 during normal tape application. For example, in a tape application system with two trays 110, the buffer component 500 on each tape 120 path includes a movable storage wheel assembly. When the tape 120 passes from the feeding component 100 through the detection component 400, it forms a downward-curving arc and is stored in the storage space of the buffer component 500.

[0048] During normal production, the buffer component 500 maintains a certain length of tape 120 in reserve through the tension adjustment mechanism. When the detection component 400 detects the label on the tape 120 of the first tray 110 and sends a material change signal, the feeding component 100 stops feeding, but the pulling component 200 continues to work. At this time, the buffer component 500 begins to release the pre-stored tape 120. The storage wheel group gradually moves upward under the action of the spring or cylinder, smoothly sending out the stored tape 120.

[0049] The buffer tape 120 in this part is sufficient to complete multiple tape application cycles, giving the operator enough time to reconnect new tape 120 at the material tray 110. After the reconnection is completed, the feeding component 100 resumes feeding, the buffer component 500 starts storing tape 120 again, and the storage roller group gradually moves down to return to the standard storage position. The whole process decouples the feeding, buffering, and pulling links, ensuring the continuity of the tape application operation.

[0050] In some embodiments, refer to Figure 1-4 It also includes a clamping component 600; the buffer component 500 is used to pull the tape 120 out of the tray 110 and form a buffer, and the clamping component 600 is used to control the locking and releasing of the tape 120; during feeding, the clamping component 600 releases the tape 120, and the buffer component 500 controls the release speed of the tape 120 to cooperate with the traction action of the pulling component 200.

[0051] For example, in an adhesive application system with two trays 110, the storage rollers of the buffer assembly 500 will actively pull out a certain length of adhesive tape 120 from the tray 110 to form a drooping buffer area in the storage space. At the same time, the clamping rollers of the clamping assembly 600 are locked to prevent the adhesive tape 120 from moving freely.

[0052] When the pulling component 200 needs to pull the tape 120 for adhesive application, after receiving the feeding signal, the clamping component 600 drives the clamping wheel away from the surface of the tape 120 through the cylinder, releasing the lock on the tape 120. At this time, the storage wheel group of the buffer component 500 begins to move upward, controlling the release speed of the tape 120 to match the pulling speed of the pulling component 200, ensuring that the tape 120 maintains appropriate tension during transmission, neither too loose causing wrinkles nor too tight causing breakage.

[0053] After each adhesive application cycle is completed, the pulling component 200 stops the traction action, and the clamping component 600 immediately presses the clamping wheel back onto the surface of the tape 120 to relock the tape 120, preventing the tape 120 from being over-released due to inertia. At the same time, the buffer component 500 uses this interval to pull the tape 120 out of the tray 110 to replenish the buffer. Through the locking and releasing coordination of the clamping component 600 and the speed control of the buffer component 500, the control and stable transmission of the tape 120 feeding are achieved.

[0054] Furthermore, refer to Figure 2 , 4 The buffer assembly 500 includes a tape-pulling buffer roller 510 and a tape-pulling cylinder 520, and the pressing assembly 600 includes a tape-pressing plate 610, a tape-pressing cylinder 620, and a tape-pressing roller 630. The tape-pulling buffer roller 510 is located between the pressing assembly 600 and the detection assembly 400. The tape-pressing cylinder 620 drives the tape-pressing plate 610 to move toward the tape-pressing roller 630 to press the tape 120, and drives the tape-pulling buffer roller 510 to move to pull the tape 120 out of the tray 110. During feeding, the tape-pressing plate 610 retracts to release the tape 120, and the tape-pulling cylinder 520 drives the tape-pulling buffer roller 510 to rotate slowly to control the release speed of the tape 120.

[0055] Understandably, the tape-pulling buffer roller 510 of the buffer assembly 500 is installed between the pressing assembly 600 and the detection assembly 400, forming a buffer area for the tape 120. During the preparation stage of the tape application system of the two trays 110, the pressure cylinder 620 first drives the pressure plate 610 to move towards the pressure roller 630, pressing the two tapes 120 onto the corresponding pressure roller 630 surfaces respectively, ensuring that the tapes 120 are stably locked. Then, the tape-pulling cylinder 520 drives the tape-pulling buffer roller 510 to move downward. Since the tape 120 is locked at the rear end by the pressing assembly 600, the downward movement of the tape-pulling buffer roller 510 will force a certain length of tape 120 to be pulled out from the tray 110, forming a U-shaped tape 120 buffer between the tape-pulling buffer roller 510 and the pressure roller 630.

[0056] When the pulling assembly 200 begins to pull the tape 120 for adhesive application, the pressure cylinder 620 drives the pressure plate 610 to retract backward, creating a gap between the pressure plate 610 and the pressure roller 630, releasing the pressure and locking on the tape 120. At the same time, the adhesive pulling cylinder 520 controls the adhesive pulling buffer roller 510 to move slowly upward. By adjusting the upward movement speed of the adhesive pulling buffer roller 510, the release speed of the tape 120 is precisely controlled, keeping it synchronized with the pulling speed of the pulling assembly 200. For example, when the pulling assembly 200 pulls the tape 120 at a speed of 100 mm per second, the adhesive pulling buffer roller 510 also moves upward at a corresponding speed to release the buffered tape 120. Through the cooperation of the mechanical structure, the tape 120 maintains a constant tension throughout the transmission process, avoiding the problem of tape 120 becoming loose or overstretched due to speed mismatch.

[0057] In some embodiments, refer to Figure 4 , 5 6. The clamping part 210 includes a glue-pulling and feeding clamp 211 and a first driving member 212; the glue-pulling and feeding clamp 211 is used to clamp each tape 120 and keep the front end of the tape 120 in a free extended state; the first driving member 212 is used to drive the glue-pulling and feeding clamp 211 to reciprocate between the feeding position and the adhesive application position, and to send the front end of the tape 120 to the adhesive application position of the corresponding battery cell 700.

[0058] For example, in the adhesive application system with two trays 110, the adhesive feeding clamp 211 clamps two tapes 120 respectively through the internal independent clamping slots. The clamping point is located about 50 mm behind the front end of the tape 120, so that the front end of the tape 120 maintains a free extension length of about 50 mm, thereby ensuring that the front end of the tape 120 will not curl or deviate during the movement.

[0059] The first drive unit 212 is a linear module driven by a servo motor, which drives the adhesive feeding clamp 211 to reciprocate in the horizontal direction. At the initial feeding position, the adhesive feeding clamp 211 is located below the buffer component 500. After clamping the two tapes 120, the first drive unit 212 starts and drives the adhesive feeding clamp 211 to move along the preset track to the adhesive application position. The moving distance can be adjusted within the range of 200-500 mm according to the placement position of the battery cell 700. After reaching the adhesive application position, the adhesive feeding clamp 211 delivers the front ends of the two tapes 120 to the corresponding two battery cells 700. The free extension of the front end of the tape 120 just covers the starting position of the battery cell 700 where adhesive needs to be applied, preparing for the subsequent pressing action of the adhesive application component 300. After the feeding is completed, the first drive unit 212 drives the adhesive feeding clamp 211 back to the feeding position to prepare for the tape 120 traction work of the next adhesive application cycle.

[0060] In some embodiments, refer to Figure 6The adhesive feeding clamp 211 includes a clamping cylinder 2111, a first clamping plate 2112, and a second clamping plate 2113. The clamping cylinder 2111 is used to drive the first clamping plate 2112 to approach the second clamping plate 2113, so as to clamp the tape 120 between the first clamping plate 2112 and the second clamping plate 2113, thereby realizing the controllable clamping and release of the tape 120.

[0061] Understandably, when the adhesive feeding clamp 211 needs to grab the tape 120 from the feeding position, the control system inputs compressed air into the clamping cylinder 2111. The cylinder piston pushes the first clamping plate 2112 to move towards the second clamping plate 2113. The two tapes 120 are simultaneously clamped at corresponding positions between the two clamping plates. The clamping force is controlled by adjusting the cylinder pressure to ensure that the tape 120 neither slips off nor is damaged. Subsequently, the first driving component 212 drives the entire adhesive feeding clamp 211 to move to the adhesive application position above the battery cell 700. During the movement, the clamping cylinder 2111 maintains pressure output, and the first clamping plate 2112 and the second clamping plate 2113 remain clamped. When the adhesive application position is reached, the control system switches the air path of the clamping cylinder 2111, causing the cylinder to depressurize and retract under the action of the internal spring. The first clamping plate 2112 quickly leaves the second clamping plate 2113, releasing the clamping of the tape 120, so that the adhesive application assembly 300 can take over the tape 120 to perform the pressing operation. The entire clamping and releasing process is achieved by pneumatic control to achieve rapid response and positioning.

[0062] In some embodiments, referring to Figures 3-5, the adhesive application assembly 300 includes a second drive member 310 and a retainer 320, with a pressing part 321 and a cutting part 322 disposed on the retainer 320; the second drive member 310 is used to drive the retainer 320 close to the adhesive application side of the battery cell 700; the pressing part 321 includes a pressing roller 3211 and a pressing cylinder 3212, and the cutting part 322 includes a cutting blade 3221 and a cutting cylinder 3222; during tape pressing, the second drive member 310 drives the retainer 320 to move to a first position, the pressing cylinder 3212 drives the pressing roller 3211 to move to a second position for pressing and applying adhesive, and the cutting cylinder 3222 drives the cutting blade 3221 to move to a third position for cutting the tape 120.

[0063] Understandably, referring to Figure 4 , 58. The adhesive application assembly 300 achieves the adhesive application action through the cooperation of the second drive member 310 and the retainer 320. The retainer 320 serves as an integrated mounting platform, which integrates the pressing roller 3211 and pressing cylinder 3212 of the pressing part 321, as well as the cutting blade 3221 and cutting cylinder 3222 of the cutting part 322. The second drive member 310 adopts a servo motor driven lifting mechanism, which can drive the entire retainer 320 to move in the vertical direction.

[0064] For example, in the adhesive application process involving two battery cells 700, after the adhesive feeding clamp 211 delivers two adhesive tapes 120 above the battery cells 700, the second drive unit 310 first drives the retainer 320 to descend from its initial high position to the first position. This position is approximately 10 mm from the surface of the battery cells 700, bringing the pressure roller 3211 and the cutter 3221 close to but not yet in contact with the surface of the battery cells 700. Subsequently, the pressure cylinder 3212 begins to operate, pushing the pressure roller 3211 to descend another 5 mm to the second position. The elastic surface on the pressure roller 3211 then contacts the adhesive tape. The tape 120 is brought into contact with the surface of the two battery cells 700 and appropriate pressure is applied. The pressure roller 3211 rolls forward along the surface of the battery cell 700 to ensure that the tape 120 is applied flat and without air bubbles. When the tape 120 is applied to the predetermined length, the cutter cylinder 3222 drives the cutter 3221 to descend quickly to the third position. The blade of the cutter 3221 precisely cuts the two tapes 120, completing one tape application cycle. The control of the three positions throughout the process ensures the consistency of the tape application quality and the accuracy of the cutting.
