The battery cell 110 has two, and the outgoing tab ends of the two battery cells 110 are oppositely arranged to define a channel suitable for accommodating the connecting sheet 130 between the two battery cells 110. In one embodiment, the battery cell 110 is a same-side outgoing tab type battery cell 110, i.e. a positive tab group and a negative tab group are arranged at the outgoing tab end of each battery cell 110.

Through the above arrangement, the extension slide plate 18 can first drive the mounting frame 12 to slide on the moving guide rail 11, so as to realize the purpose of pulling out the inflatable shaft 121 from the battery tab protection adhesive pasting device. In addition, the mounting frame 12 can continue to move along the extension slide plate 18 in a direction away from the adhesive cutting mechanism 3, so that the mounting frame 12 can further adjust the position of the adhesive replacement according to the actual working condition, so that the position of the adhesive replacement is more flexible and safer during the replacement of the adhesive.

[0044] Specifically, in the embodiment, the movable protrusion 13 comprises a first lifting movement block 131 and a second lifting movement block 132, and a first limiting air cylinder 123 and a second limiting air cylinder 124 are fixedly installed on the mounting frame 12, the output end of the first limiting air cylinder 123 is connected to the first lifting movement block 131, and the first lifting movement block 131 is selectively connected to the limiting groove on the first limiting block 14 and the second limiting block 15.

[0045] Optionally, in the embodiment, two spare adhesive mechanisms 1 are provided, and the adhesive pasting mechanism 4 is selectively arranged in butt joint with one of the spare adhesive mechanisms 1, so that when the second inductor 17 detects that the adhesive roll on one of the spare adhesive mechanisms 1 is used up, the adhesive pasting mechanism 4 can be butt jointed with the other spare adhesive mechanism 1 and continue to paste the adhesive, so that the two spare adhesive mechanisms 1 can realize the adhesive replacement without stopping through the circulating exchange mode, thereby ensuring the working efficiency.

Through the above arrangement, the clamp cylinder 24 can control the clamp block 25 to clamp the adhesive tape 140 led out from the adhesive preparation mechanism 1, and the pulling motor 23 can control the clamp block 25 to move along the direction close to or away from the adhesive cutting mechanism 3 through the second horizontal linear drive module 22, so that the clamp block 25 can pull out the adhesive tape 140 by a certain distance according to the setting, so as to facilitate the subsequent adhesive cutting mechanism 3 to cut the pulled out adhesive tape 140.

[0048] More specifically, the adhesive pulling mechanism 2 further comprises a third sensor 26, the third sensor 26 is electrically connected to the clamp cylinder 24, so as to accurately judge whether the adhesive tape 140 is stretched to the required length by detecting the distance of the clamp cylinder 24 moving on the second horizontal linear drive module 22.

[0049] Reference Figure 3 As shown, one of the embodiments of the present embodiment is that the adhesive cutting mechanism 3 is arranged on the mounting frame 12 and comprises a cutting cylinder 31 and a cutting knife 32, the fixed end of the cutting cylinder 31 is fixedly connected to the mounting frame 12, and the output end of the cutting cylinder 31 is drivingly connected to the cutting knife 32 in the vertical direction, so that the cutting knife 32 can perform ascending or descending movement, when the adhesive pulling mechanism 2 pulls the adhesive tape 140 to the required length, the cutting cylinder 31 can drive the cutting knife 32 to descend to cut the adhesive tape 140, and can drive the cutting knife 32 to ascend again to prepare for the next cutting action, thereby ensuring an automatic and stable cutting process and reducing human intervention.

[0050] It should be noted that the cutter 32 is coated with an anti-sticking layer, which can be Teflon, titanium nitride, polytetrafluoroethylene or the like, and the utility model is not limited to this, so that the cutter 32 can be prevented from sticking to the glue, and the pressure of cleaning the cutter 32 is reduced.

[0051] Optionally, the battery tab protection adhesive pasting device provided by the embodiment further comprises a glue pressing mechanism 7, which is arranged between the glue pulling mechanism 2 and the glue cutting mechanism 3 and is used for pressing the adhesive tape 140 pulled out by the glue pulling mechanism 2, so as to ensure the accuracy of the glue cutting position of the glue cutting mechanism 3.

[0052] Specifically, the glue pressing mechanism 7 is arranged on the mounting frame 12, so that the glue cutting mechanism 3 can cut the pressed adhesive tape 140, and the integrity of the glue cutting mechanism 3, the glue pressing mechanism 7 and the glue preparing mechanism 1 is improved, and the space occupancy is reduced. In one of the embodiments of the embodiment, the glue pressing mechanism 7 comprises a glue pressing cylinder 71, a first pressing block 72 and a second pressing block 73, wherein the fixed end of the glue pressing cylinder 71 is fixedly connected to the mounting frame 12, the output end of the glue pressing cylinder 71 is drivingly connected to the first pressing block 72 in the vertical direction, and the second pressing block 73 is fixedly arranged below the first pressing block 72 and defines a channel for the adhesive tape 140 to pass through between the first pressing block 72 and the second pressing block 73.

[0053] Specifically, referring to Figure 5As shown, in the present embodiment, the taping mechanism 4 comprises a taping driving assembly 41 and a suction block 42, wherein the taping driving assembly 41 is arranged between the taping position and the cutting mechanism 3, and the suction block 42 is drivingly connected to the taping driving assembly 41, so that the taping driving assembly 41 can drive the suction block 42 to reciprocate between the cutting mechanism 3 and the taping position. The suction block 42 is provided with a suction surface for suctioning both ends of the cut-off adhesive tape 140, and the suction surface is partially arranged on the surface of the battery cell 110 and the other part of the suction surface is arranged on the connecting tab 130, so that the both ends of the adhesive tape 140 can be adhered to the surface of the battery cell 110 and the connecting tab 130 respectively, and the middle part of the adhesive tape 140 can cover the welding part between the connecting tab 130 and the tab 120. In this way, the position between the connecting tab 130 and the battery cell 110 can be kept relatively fixed, the installation stability of the tab 120 on the battery cell 110 is higher, and the welding point between the connecting tab 130 and the tab 120 can be effectively avoided from being exposed, the use safety of the battery cell 110 and the tab 120 is ensured, and the demand for efficiently and high-quality taping of the tab 120 of the paralleled square battery pack 100 is realized.

[0054] More specifically, in one of the embodiments of the present embodiment, the taping driving assembly 41 comprises a first horizontal linear driving module 411 and a lifting driving module 412, wherein the first horizontal linear driving module 411 is horizontally arranged between the cutting mechanism 3 and the taping position, the lifting driving module 412 is movably arranged on the first horizontal linear driving module 411 in the horizontal direction, and the output end of the lifting driving module 412 is drivingly connected to the suction block 42, so that the suction block 42 can be lifted or lowered in the vertical direction.

[0055] Through the above arrangement, the first horizontal linear driving module 411 can automatically drive the suction block 42 to move horizontally to the position directly below the cutting mechanism 3, and then the lifting driving module 412 drives the suction block 42 to lift to suction the adhesive tape 140, and then the lifting driving module 412 drives the suction block 42 to lower to a safe height, and then the first horizontal linear driving module 411 drives the suction block 42 to move horizontally in the direction close to the taping position until the suction block 42 moves to the position directly below the taping position, and finally the lifting driving module 412 drives the suction block 42 to lift and approach the taping position, so that the suction block 42 can adhere the adhesive tape 140 to the surface of the battery cell 110 and the connecting tab 130, and the taping process is automatically completed, thereby ensuring the taping efficiency.

[0056] More specifically, in this embodiment, the suction block 42 includes a first suction head 421, a second suction head 422, and an elastic reset element 423. The first suction head 421 and the second suction head 422 are arranged side-by-side and spaced apart, and each of the first and second suction heads 421 and 422 has an suction surface for adsorbing the end of the adhesive tape 140. It is understood that the suction surfaces of the first and second suction heads 421 and 422 have multiple suction holes communicating with a vacuum suction device. The elastic reset element 423 connects the first suction head 421 and the adhesive application drive assembly 41. Preferably, the elastic reset element 423 is a compression spring. The elastic reset element 423 is configured such that when the elastic reset element 423 is in the restored state, the adsorption surfaces of the first adsorption head 421 and the second adsorption head 422 are aligned so that the tape 140 can be adhered to the suction block 42 in a horizontal state, effectively preventing the tape 140 from being pulled and torn during transportation; when the elastic reset element 423 is in the pre-tightened state, the adsorption surface of the first adsorption head 421 is pressed against the surface of the battery cell so that one end of the tape 140 can be adhered to the surface of the battery cell, while the adsorption surface of the second adsorption head 422 is pressed against the connecting piece 130 so that the other end of the tape 140 is adhered to the connecting piece 130, thereby enabling the tape 140 to be stably and reliably adhered to the surface of the battery cell and the connecting piece 130 in a Z-shaped posture.

[0057] Understandably, as the other end of the tape 140 moves toward the connecting piece 130, the elastic reset element 423 is always in a compressed state, which ensures that one end of the tape 140 can always maintain an adhesive relationship with the surface of the battery cell, thus preventing the tape 140 from falling off the surface of the battery cell.

[0058] More specifically, in this embodiment, reference is made to... Figure 6 As shown, the suction block 42 also includes a guide plate 424, which includes a fixed part 4241 and a sliding part 4242 connected in a T-shape. The fixed part 4241 is horizontally arranged, with one side fixedly connected to the adhesive driving assembly 41 and the other side fixedly connected to the sliding part 4242. An elastic reset element 423 is connected between the first suction head 421 and the other side of the fixed part 4241. The sliding part 4242 is vertically arranged, with one end fixedly connected to the fixed part 4241 and the other end of the sliding part 4242 being provided with the aforementioned second suction head 422. In addition, the sliding part 4242 is also provided with a guide rail extending in the vertical direction, and the first adsorption head 421 is provided with a groove that is slidably connected to the guide rail, so that under the guiding and limiting action of the groove and the guide rail, the elastic reset element 423 can be stably compressed in the vertical direction, avoiding the elastic reset element 423 from becoming skewed during compression, which would cause the adsorption surface of the first adsorption head 421 to be uneven with the surface of the battery cell, resulting in the tape 140 not being firmly bonded to the surface of the battery cell.

[0059] Further, the cross-sectional area of the suction surface of the second suction head 422 is larger than that of the first suction head 421, so as to increase the suction force of the second suction head 422 on the other end of the adhesive tape 140. Since the middle part of the adhesive tape 140 needs to be avoided from the welding between the tab 120 and the connecting piece 130, and the middle part of the adhesive tape 140 is prevented from being bonded to the welding of the two, which affects the use performance of the battery cell 110, after the two ends of the adhesive tape 140 are bonded to the surface of the battery cell and the connecting piece 130 respectively, the middle part of the adhesive tape 140 needs to be kept in a tension state as much as possible. When the second suction head 422 with the other end of the adhesive tape 140 approaches the connecting piece 130, the middle part of the adhesive tape 140 can be pulled to be in a tension state. By increasing the suction force of the second suction head 422, the embodiment can avoid the situation that the second suction head 422 is loosened from the other end of the adhesive tape 140 during the process of pulling the middle part of the adhesive tape 140, so as to ensure that the adhesive tape 140 can be safely and reliably adhered to the square parallel battery pack 100.

[0060] Optionally, the first horizontal linear drive module 411 is further provided with a first sensor 413, and the first sensor 413 is electrically connected to the lifting drive module 412. The first sensor 413 can detect the position of the lifting drive module 412 on the first horizontal linear drive module 411, so as to accurately judge whether the suction block 42 moves to the adhesive position or directly below the adhesive tape cutting mechanism 3, thereby helping to improve the adhesive quality.

[0061] Optionally, in the embodiment, the suction block 42 is provided with two in parallel, so as to simultaneously adhere two cut adhesive tapes 140 to two adhesive positions. The adhesive mechanism 4 can simultaneously adhere to two adhesive positions, thereby effectively improving the production efficiency. Correspondingly, the adhesive tape fixing position, the guide roller 122, the adhesive tape cutting mechanism 3 and the adhesive tape pulling mechanism 2 are all provided with two. Of course, in other embodiments, three, four or more suction blocks 42 and corresponding components can be provided in parallel according to the process needs, so as to simultaneously adhere three, four or more adhesive tapes 140 to three, four or more adhesive positions. The utility model is not limited thereto.

[0062] In the embodiment, the adhesive driving assembly 41 further comprises a first rotary driving assembly 414, a second rotary driving assembly 415 and a fixed disc 416, wherein the first rotary driving assembly 414 is provided with two corresponding to the suction blocks 42, and the fixed ends of the two first rotary driving assemblies 414 are fixedly connected to the same fixed disc 416, the fixed disc 416 is fixedly connected to the output end of the second rotary driving assembly 415, and the fixed end of the second rotary driving assembly 415 is connected to the lifting driving module 412. Through the above setting, the first rotary driving assembly 414 can drive the suction block 42 to rotate horizontally by 90°, and then be transmitted to the lower side of the adhesive cutting mechanism 3 by the first horizontal linear driving module 411 to adsorb the adhesive tape 140, and by adjusting the posture of the suction block 42, the suction block 42 can be precisely connected with the adhesive tape 140. The setting of the second rotary driving assembly 415 can drive the two suction blocks 42 to rotate around the vertical direction at the same time, so that the two adhesive tapes 140 on the two suction blocks 42 can be precisely aligned with the corresponding adhesive positions, thereby realizing the purpose that the two adhesive tapes 140 are accurately moved from the adhesive cutting mechanism 3 to the corresponding adhesive positions, the degree of automation is high, and the production efficiency is high.

[0063] It should be noted that the two adhesive preparation mechanisms 1, the two adhesive pulling mechanisms 2, the two adhesive cutting mechanisms 3, the adhesive pressing mechanism 7, the adhesive applying mechanism 4 and the load fixture 200 for placing the battery cell 110 jointly constitute an adhesive applying station, and the adhesive applying station can only apply adhesive to the adhesive position formed between the connecting piece 130 and the battery cell 110 on one side. In the embodiment, the battery tab protection adhesive applying device comprises two parallel adhesive applying stations, and the other adhesive applying station can apply adhesive to the adhesive position formed between the connecting piece 130 and the battery cell 110 on the other side, so that the two positive tab groups can be fixedly connected with the corresponding battery cells 110 by the adhesive tapes 140.

[0064] The working principle of the battery tab protection adhesive applying device is as follows:

[0065] (1) The first limiting cylinder 123 and the second limiting cylinder 124 make the first lifting movement block 131 and the second lifting movement block 132 retract and leave the limiting grooves of the first limiting block 14 and the third limiting block 182, and the mounting frame 12 is moved to the positions of the second limiting block 15 and the fourth limiting block 183 with the extension slide rail 181 and the moving guide rail 11 through the handle 16, and the first limiting cylinder 123 and the second limiting cylinder 124 are started again to make the first lifting movement block 131 and the second lifting movement block 132 extend and insert into the corresponding limiting grooves, so that the adhesive fixing position can be pulled out of the device for adhesive preparation.

[0066] (2) When the adhesive tape is prepared, the film is first fixed in the air expansion shaft 121, and then the adhesive tape 140 is pulled out and guided by the guide roller 122 into the channel between the first pressing block 72 and the second pressing block 73. The pressing cylinder 71 is started to enable the first pressing block 72 to descend and press the adhesive tape 140 tightly on the second pressing block 73. Then, the step (1) is performed in the reverse operation process to make the mounting frame 12 return to the original position.

[0067] (3) The tape pulling motor 23 is started to move the slider in the second horizontal linear drive module 22, the clip cylinder 24 and the clip block 25 to the tape pulling position, and the third inductor 26 detects the moving distance to ensure the accuracy of the position of the clip cylinder 24 and the clip block 25. Then, the clip cylinder 24 is started to make the clip block 25 clamp the adhesive tape 140, and the output end of the clip cylinder 24 is retracted. At the same time, the tape pulling motor 23 is started to make the clip cylinder 24 and the clip block 25 retreat and move horizontally away from the tape cutting mechanism 3 to pull the adhesive tape.

[0068] (4) The two first rotary drive assemblies 414 are started to rotate the corresponding two suction blocks 42 by 90°, and the lifting drive module 412 is started to make the suction block 42 rise to the adhesive taking position. After the vacuum is opened, the suction block 42 can suck the adhesive tape 140. Then, the tape cutting cylinder 31 is started to make the cutter 32 extend downward to cut the adhesive tape 140. The clip cylinder 24 is started to control the first pressing block 72 to move away from the second pressing block 73, and the tape cutting cylinder 31 controls the cutter 32 to retreat.

[0069] (5) The lifting drive module 412 controls the suction block 42 to descend, and the tape pulling motor 23 is started to control the suction block 42 to move to the right below the adhesive applying position. The first inductor 413 detects the moving distance of the lifting drive module 412 to determine whether the suction block 42 moves to the specified position accurately. Then, the first rotary drive assembly 414 is started to rotate the suction block 42 by 90° to the original position, and the second rotary drive assembly 415 is started to rotate the fixing disc 416 by 90° to ensure that the adhesive tape 140 is aligned with the adhesive applying position. Then, the lifting drive module 412 makes the suction block 42 rise to control the adhesive tape 140 to move in the direction close to the adhesive applying position.

[0070] (6) During the rising of the adhesive tape 140, the first suction head 421 in the suction block 42 first adheres to the surface of the battery cell to make one end of the adhesive tape 140 adhere to the surface of the battery cell, and the elastic return element 423 is in the pre-tightening state to ensure the stable adhesion between the adhesive tape 140 and the surface of the battery cell. The second suction head 422 continues to move upward until the other end of the adhesive tape 140 is attached to the connecting piece 130, thereby completing the Z-shaped adhesive application.

[0071] (7) The lifting drive module 412 is activated, causing the suction block 42 to descend, and the above steps (1) to (6) are repeated until the adhesive is applied between one of the cells 110 in the square parallel battery pack 100 and the connecting piece 130.

[0072] (8) The robot arm picks up the square parallel battery pack 100 and places it on another adhesive application station. The other adhesive application station is used to apply adhesive to another cell 110 in the square parallel battery pack 100 and the connecting piece 130.

[0073] (9) When the second sensor 17 detects that the film roll on one of the glue preparation mechanisms 1 is used up, the interactive cylinder 5 is activated to move the other glue preparation mechanism 1 to the position of the first glue preparation mechanism 1, so that the other glue preparation mechanism 1 docks with the glue cutting mechanism 3, thereby continuing to apply glue.
