[0025] like Figure 1 As shown, a battery cell gluing device provided in one embodiment of the present invention is used to apply adhesive tape to the surface of a battery cell 400. The battery cell gluing device includes a glue taking unit 100, a glue cutting unit 200, and a glue applying unit 300. The pre-cutting unit 200 is used to cut the adhesive tape to obtain a fixed length of adhesive tape. The glue taking unit 100 is used to pick up the fixed length of adhesive tape and transfer the adhesive tape to the glue applying unit 300. The glue applying unit 300 then adheres the adhesive tape to the surface of the battery cell 400.

[0026] The following will illustrate the battery cell gluing device by taking a square-shaped battery cell 400 as an example. It can be understood that by using different devices to provide and fix the battery cell 400 to cooperate with the battery cell gluing device, the battery cell gluing device can also realize gluing of battery cells 400 of other shapes.

[0027] Also refer to Figure 2 The adhesive dispensing unit 100 includes a substrate 110, a slide 120, a support 130 and two gripping fingers 140, 141. The substrate 110 is a support for other components and can be a base frame or other fixed plate member of the battery cell adhesive dispensing device.

[0028] The slide 120 is slidably mounted on the base plate 110. The slide 120 can be driven by a motor, cylinder, or other drive element to slide relative to the base plate 110. In one embodiment, the slide 120 is threadedly connected to a screw 121. A slide rail 122 is provided on the base plate 110 to mate with the slide 120. A motor 123 is provided at one end of the screw 121. The motor 123 drives the screw 121 to rotate, thereby causing the slide 120 to move relative to the base plate 110 along the slide rail 122.

[0029] The support 130 can move along the slide rail 122 together with the slide 120. At the same time, the support 130 can slide relative to the slide 120 with the help of a sliding mechanism. The support 130 can be driven by a driving member such as a motor and a pressure cylinder to slide relative to the slide 120. In a specific embodiment, a slide plate 124 and a slider 134 that cooperate with each other are provided between the slide 120 and the support 130, and relative movement is achieved by cylinder drive, wherein the slide plate 124 is fixedly connected to the slide 120, and the slider 134 is connected to the support 130, thereby achieving relative movement between the support 130 and the slide 120. The movement direction of the slide 120 relative to the substrate 110 is different from the movement direction of the support 130 relative to the slide 120. Specifically, the movement direction of the slide 120 relative to the substrate 110 is perpendicular to the movement direction of the support 130 relative to the slide 120. Furthermore, the support 130 and the slider 134 can achieve relative movement through another cylinder 143, wherein the movement direction of the support 130 relative to the slider 134 is different from the movement direction of the slide 120 relative to the substrate 110 and the movement direction of the support 130 relative to the slide 120. Figure 2 In the embodiment shown, the movement direction of the support 130 relative to the slider 134, the movement direction of the slide 120 relative to the substrate 110, and the movement direction of the support 130 relative to the slide 120 are perpendicular to each other. With the help of this mechanism, the displacement of the support 130 in the three-dimensional direction is achieved, and then the displacement of the two clamping fingers 140 and 141 set on the support 130 in the three-dimensional direction is achieved.

[0030] Two clamping fingers 140, 141 are arranged on the support 130. The clamping fingers 140, 141 are used to clamp the adhesive tape. Figure 2 1 shows a certain length of adhesive tape 500 cut from an adhesive tape roll, and one side edge of the adhesive tape 500 is clamped by the clamping fingers 140 and 141. The opening and closing of the clamping fingers 140 and 141 can be controlled by components such as solenoid valves.

[0031] Driven by the slide 120, the slider 134 and the support 130, the positions of the clamping fingers 140 and 141 can be changed in three different directions, and then by controlling the opening and closing of the clamping fingers 140 and 141, the clamping fingers 140 and 141 can be clamped and released at different positions of the adhesive tape 500.

[0032] Furthermore, a slot can be provided on the support 130, and the two clamping fingers 140, 141 can be slidably disposed in the slot to adjust the distance between the two clamping fingers 140, 141 to clamp adhesive tapes 500 of different fixed lengths. Therefore, the battery cell adhesive laminating device provided by the present invention can accommodate adhesive tapes of different lengths by simply adjusting the distance between the two clamping fingers 140, 141, thus having good versatility.

[0033] Also refer to Figure 1 、 Figure 2 and Figure 3 The rubber cutting unit 200 includes an unwinding frame 210 , a first pair of pressing blocks 220 , a second pair of pressing blocks 230 and a cutter 240 .

[0034] The unwinding frame 210 is provided with a tape roll 501. By rotating the unwinding frame 210, the tape roll 501 can be released, and the free end 502 of the tape of the tape roll 501 can be exposed from the unwinding frame 210. The unwinding frame 210 is arranged on the substrate 110. In one embodiment, the unwinding frame 210 is located on one side of the substrate 110, and the axial direction of the unwinding frame 210 is roughly parallel to the substrate 110, and thus has a different orientation from components such as the slide 120 provided on the substrate 110. In some embodiments, an auxiliary substrate 201 can be further provided to connect to the substrate 110, and the auxiliary substrate 201 and the substrate 110 can roughly form an L-shaped structure. Components such as the unwinding frame 210, the first pressure block pair 220, the second pressure block pair 230, and the cutter 240 can be arranged on the auxiliary substrate 201. In some embodiments, the auxiliary substrate 201 and the substrate 110 can be integrally constructed.

[0035] The first pressing block pair 220 and the second pressing block pair 230 are arranged on the travel path of the free end 502 of the adhesive tape roll 501. When the adhesive tape cutting unit 200 is working, the free end 502 of the adhesive tape roll 501 passes through the first pressing block pair 220 and the second pressing block pair 230 in sequence, and is clamped and fixed by the first pressing block pair 220 and the second pressing block pair 230. The adhesive tape 500 is then cut by the cutter 240 to obtain a certain length, and is then clamped by the two clamping fingers 140 and 141 (as shown in FIG. Figure 2 ).

[0036] The first pressure block pair 220 includes two opposing pressure blocks 221 and 222. Pressure block 221 is fixed and immovable, while pressure block 222 is movably mounted on the auxiliary base plate 201 and driven relative to pressure block 221 by a drive element such as a cylinder. To clamp the free end 502 of the adhesive tape roll 501, pressure block 222 moves toward pressure block 221. Conversely, to release the free end 502 of the adhesive tape roll 501, pressure block 222 moves away from pressure block 221, allowing the free end 502 of the adhesive tape roll 501 to pass through the first pressure block pair 220.

[0037] The second pressure block pair 230 includes two relatively arranged pressure blocks 231 and 232. Both pressure blocks 231 and 232 are movably arranged, wherein the pressure block 231 can be set on the substrate 110, and the pressure block 232 can be set on the auxiliary substrate 201. They can be driven by a driving member such as a cylinder to move toward or away from each other to clamp or release the free end 502 of the adhesive tape roll 501.

[0038] The cutter 240 is disposed at the second pair of pressing blocks 230. In one embodiment, the cutter 240 is disposed on a side of the second pair of pressing blocks 230 away from the first pair of pressing blocks 220. The cutter 240 is used to cut the free end 502 of the adhesive tape roll 501 to obtain a fixed length of adhesive tape 500. Before the cutter 240 cuts the free end 502, the two clamping fingers 140 and 141 complete the clamping action. After the cutter 240 cuts the free end 502, the clamping fingers 140 and 141 clamp one side edge of the cut adhesive tape 500 (e.g., Figure 2 ).

[0039] The cutter 240 may be driven by the same driving member used to drive the second pressure block pair 230 , or by providing an independent driving member.

[0040] Furthermore, the adhesive cutting unit 200 includes a movable adhesive sheet 250. The adhesive sheet 250 serves as an auxiliary tool, supporting the adhesive side of the adhesive sheet 500 and moving it toward the adhesive laminating unit 300 to assist in transferring the cut adhesive sheet 500 to the adhesive laminating unit 300. To reduce the bonding area between the adhesive sheet 250 and the adhesive sheet 500, the adhesive sheet 250 can be linear, or pins can be provided on the contact surface between the adhesive sheet 250 and the adhesive sheet 500 to ensure point contact between the adhesive sheet 250 and the adhesive sheet 500.

[0041] The adhesive tape pressing sheet 250 can be driven by a cylinder 251 . The cylinder 251 can be disposed on the base plate 110 or on other fixed plates.

[0042] Furthermore, the rubber cutting unit 200 further includes a plurality of rubber rollers 260 and a transmission mechanism 270 disposed on the substrate 110. Figure 3 In the illustrated embodiment, the rubber roller 260 and transmission mechanism 270 are mounted directly on the auxiliary base plate 201. When the free end 502 of the adhesive tape roll 501 is released, it is guided by the rubber roller 260 and then passes through the first pair of pressure blocks 220. The transmission mechanism 270 is used to adjust the position of at least one rubber roller 260 to adjust the tension of the adhesive tape roll. The transmission mechanism 270 can be a pull rod structure driven by a cylinder or the like. The pull rod pulls the rubber roller 260, changing the path of the free end 502 and thereby varying the tension on the free end 502.

[0043] Also refer to Figure 1 and Figure 4 The glue sticking unit 300 is used to stick the adhesive tape 500 transferred from the glue taking unit 100 onto the battery cell 400 . The glue sticking unit 300 includes a main shaft 310 , a swing arm 320 , a glue sticking roller 330 , a push plate mechanism 340 and a pull plate mechanism 350 .

[0044] The main shaft 310 can be connected to the base frame of the battery cell gluing device together with the substrate 110 through a structure such as a bracket, and the main shaft 310 can also be supported by an independently provided bracket.

[0045] The swing arm 320 is rotatably mounted on the main shaft 310. The swing arm 320 has a first end 321 and a second end 322 opposite to each other. The main shaft 310 is passed through the connection between the first end 321 and the second end 322 of the swing arm 320. In one embodiment, the first end 321 and the second end 322 are arranged at an angle. Figure 4 As shown in FIG, the first end 321 and the second end 322 are substantially at a right angle to each other, so that the swing arm 320 as a whole has an L-shaped structure.

[0046] The adhesive roller 330 is rotatably mounted on the first end 321 of the swing arm 320. The roller surface of the adhesive roller 330 may be provided with air holes. By generating negative pressure or a certain degree of vacuum within the adhesive roller 330, the smooth side (i.e., the non-adhesive side) of the adhesive tape 500 is attracted to the adhesive roller 330. After the adhesive roller 330 absorbs the adhesive tape 500, the swing arm 320 rotates the adhesive roller 330 to position it at the battery cell 400. Further rotation of the adhesive roller 330 causes the adhesive side of the adhesive tape 500 to adhere to the battery cell 400, completing the adhesive application process.

[0047] The push plate mechanism 340 is provided on the second end 322 of the swing arm 320 for pushing the swing arm 320 in a predetermined direction. Figure 4 In the perspective shown, the push plate mechanism 340 applies a thrust generally toward the right, so that the glue roller 330 on the swing arm 320 can approach the position of the battery cell 400 so that the adhesive tape 500 adsorbed by the glue roller 330 can be adhered to the surface of the battery cell 400.

[0048] The pulling mechanism 350 is provided at the second end 322 of the swing arm 320 and is used to pull the swing arm 320 in a direction opposite to the predetermined direction. Figure 4In the illustrated perspective, the pull mechanism 350 applies a pulling force generally toward the left. When the push mechanism 340 pushes the swing arm 320 to a preset position, the pull mechanism 350 pulls the swing arm 320 in the opposite direction, securing it in the preset position. This preset position is the gluing position. In this gluing position, the adhesive tape 500 can be applied to the battery cell 400 by rotating the adhesive roller 330. It will be appreciated that the swing arm 320 also has a suction position, in which the adhesive tape 500 picked up by the adhesive removal unit 100 is attracted to the adhesive roller 330. In other words, the change in the output distance of the push mechanism 340 and the pull mechanism 350 jointly determines the swing angle of the swing arm 320, switching the adhesive roller 330 between the suction position and the gluing position, thereby enabling the adhesive roller 330 to absorb the adhesive tape 500 and adhere it to the surface of the battery cell 400.

[0049] In the present invention, the preset position of the swing arm 320 is jointly determined by the push plate mechanism 340 and the pull plate mechanism 350. The preset position can be changed by simply adjusting the output distance of the push plate mechanism 340 and the pull plate mechanism 350, thereby meeting the needs of different gluing positions and avoiding the disadvantages of the prior art such as the inability to accurately glue or unsuccessful gluing caused by changes in the gluing position due to different models of battery cells 400.

[0050] Furthermore, a bearing 360 is provided on the second end 322 of the swing arm 320. The push plate mechanism 340 and the pull plate mechanism 350 both abut against the bearing 360 to push or pull the swing arm 320. Since the bearing 360 is rotatable, the push plate mechanism 340 and the pull plate mechanism 350 can reduce friction when interacting with the second end 322, thereby facilitating the change or fixation of the swing arm 320.

[0051] In one embodiment, the plate pushing mechanism 340 and the plate pulling mechanism 350 are both disposed on a plate body 370. The plate body 370 can be disposed independently or indirectly connected to the base plate 110.

[0052] The push plate mechanism 340 includes a push plate 341, which is driven and mounted on the plate body 370, and a push block 342, which is driven and mounted on the push plate 341. The push block 342 is configured to abut against one side of the second end 322 of the swing arm 320. Both the push plate 341 and the push block 342 can be driven and mounted by pneumatic cylinders. For example, the push plate 341 is driven and mounted on the plate body 370 by one pneumatic cylinder, while the push block 342 is driven and mounted on the push plate 341 by another pneumatic cylinder. By separately mounting the push plate 341 and the push block 342, the push plate 341 can initially position the swing arm 320, while the push block 342 can precisely position the swing arm 320. This allows the swing arm 320 to be more accurately rotated to a desired position, thereby enabling the adhesive roller 330 to more accurately reach a predetermined position.

[0053] The plate-pulling mechanism 350 includes a pull block 351. The pull block 351 and the push block 342 are respectively configured to abut against opposite sides of the second end 322 of the swing arm 320, thereby positioning the swing arm 320. To stagger the pull block 351 and the push block 342 so that they do not interfere with each other, the pull block 351 and the push block 342 are positioned axially at opposite ends of the bearing 360. The plate-pulling mechanism 350 also includes a cylinder 352 for driving the pull block 351 and a guide rod 353 for guiding the pull block 351. Both the cylinder 352 and the guide rod 353 are mounted on the plate body 370.

[0054] In some embodiments, a motor 311 is disposed at one end of the main shaft 310 to drive the rotation of the main shaft 310. The main shaft 310 and the adhesive roller 330 are connected via a transmission member 312, such as a belt drive. Rotation of the main shaft 310 drives rotation of the adhesive roller 330. It will be appreciated that the rotation of the main shaft 310 and the swinging of the swing arm 320 do not interfere with each other. In other embodiments, the rotation of the adhesive roller 330 can also be achieved by a drive member disposed on the first end 321 of the swing arm 320, without requiring the transmission member 312 to connect the main shaft 310 and the adhesive roller 330.

[0055] The working process of the battery cell gluing device provided by one embodiment of the present invention will be described below in conjunction with the above drawings.

[0056] When it is necessary to tape a predetermined battery cell 400, the glue cutting unit 200 fixes the free end 502 of the released adhesive tape roll 501 through the first and second pressing block pairs 220 and 230, and exposes the free end 502 of a predetermined length on the side of the second pressing block pair 230 facing away from the first pressing block pair 220. The free end 502 of the predetermined length is the adhesive tape 500 to be cut off by the cutter 240 to obtain the predetermined length. The glue removing unit 100 moves the two clamping fingers 140 and 141 to the side of the second pressing block pair 230 facing away from the first pressing block pair 220 through the actuation of the slide 120 and the support 130, and controls the clamping fingers 140 and 141 to clamp one side edge of the free end 502 to be cut off through the control of the cylinder 143. Then, the cutter 240 is actuated to cut the free end 502 to obtain the adhesive tape 500 of the predetermined length. After the gripping fingers 140 and 141 of the adhesive dispensing unit 100 grip one edge of the adhesive tape 500, the support 130 moves toward the adhesive roller 330. Simultaneously, the adhesive tape pressing plate 250 assists in lifting the adhesive tape 500, bringing it closer to the adhesive roller 330, facilitating its absorption. The adhesive dispensing unit 300, through the push plate mechanism 340 and pull plate mechanism 350, moves the adhesive roller 330 on the swing arm 320 to a preset position until the smooth side of the adhesive tape 500 is close to the adhesive roller 330 and is attracted to it. The gripping fingers 140 and 141 then release the adhesive tape 500 and return to their original position, ready for the next gripping operation.

[0057] The adhesive roller 330, having absorbed the adhesive tape 500, is moved to the adhesive application position by the push plate mechanism 340 and the pull plate mechanism 350 and locked in the adhesive application position. The adhesive roller 330 then rotates to adhere the adhesive tape 500 to the battery cell 400. The adhesive roller 330 then returns to the preset position to wait for the next absorption, and this cycle repeats.

[0058] The battery cell gluing device provided by the present invention can adapt to the gluing needs of different positions by changing the position of the gluing roller in the gluing unit; in addition, since the clamping fingers in the glue taking unit can move in multiple directions, it can not only clamp adhesive tapes of different lengths, but also adapt to transferring adhesive tapes to gluing rollers in different positions so that the adhesive tapes are successfully adsorbed by the gluing rollers, thus having strong versatility.

[0059] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
