Description

Technical Field

[0001] The present application belongs to the field of battery cell processing equipment, and more specifically, relates to a battery cell gluing device. Background Art

[0002] Lithium battery cells are generally made through a winding process. Usually, the positive electrode sheet, negative electrode sheet, and separator are stacked in a certain order, and then wound to a certain length by the winding needle of the winding head. After the winding is completed, the rolled battery cells are bundled with tape to prevent the rolled battery cells from loosening again.

[0003] Currently, battery cell taping devices tape rolled battery cells by attaching one end of the tape to the outer circumference of the cell. The winding needle then rotates the cell, causing the tape to wrap around the outer circumference. Once the tape is completely wound around the cell, it is cut. This results in a long taping process and low efficiency. Furthermore, during taping, the rotation of the cell pulls on the tape, resulting in a strong wrapping force on the cell, which can affect the cell's internal structure and hinder the needle's ability to remove the core.

[0046] See also Figures 1 to 3 The battery cell gluing device 100 provided in this application is now described. The battery cell gluing device 100 includes a glue feeding mechanism 30, a glue cutting mechanism 40, a glue sticking mechanism 20, and a core fixing mechanism 50. The glue feeding mechanism 30 is used to clamp and pull the supply tape 92, thereby automatically supplying the tape 92 to the gluing mechanism 20. The glue cutting mechanism 40 is used to cut the tape 92. When in use, after the glue feeding mechanism 30 supplies a set length of tape 92, the glue cutting mechanism 40 cuts the tape 92. This not only facilitates the glue feeding mechanism 30 to continue to convey the tape 92, but also facilitates the glue sticking mechanism 20 to stick glue.

[0047] Please also refer to Figure 9 and Figure 10 The gluing mechanism 20 includes a gluing assembly 21, a core stabilizing assembly 22, and a glue pushing assembly 23. The gluing assembly 21 is used to stick the tape 92 cut by the glue cutting mechanism 40 to the battery cell. The core fixing mechanism 50 and the core stabilizing assembly 22 are spaced apart. The core stabilizing assembly 22 is used to hold one side of the battery cell, and the core fixing mechanism 50 is used to hold the other side of the battery cell. The gluing assembly 21 is located between the core fixing mechanism 50 and the core stabilizing assembly 22. In this way, when gluing, the core stabilizing assembly 22 and the core fixing mechanism 50 can be used to hold two positions on the circumference of the battery cell. The battery cell is on the winding needle, which can better stabilize the battery cell and facilitate the winding needle to drive the battery cell to rotate smoothly, so that the gluing assembly 21 sticks the tape 92 to the battery cell.

[0048] The glue pushing assembly 23 is used to push the tape 92 supplied by the glue feeding mechanism 30 to the glue sticking assembly 21. That is, the glue feeding mechanism 30 transfers the tape 92 to the glue pushing assembly 23, and the glue pushing assembly 23 pushes the tape 92 to the glue sticking assembly 21 so that the glue sticking assembly 21 can stick the tape 92 on the battery cell.

[0049] The glue feeding mechanism 30, the glue cutting mechanism 40, the glue applying assembly 21 and the glue pushing assembly 23 are located between the core fixing mechanism 50 and the core stabilizing assembly 22, so that when in use, the core fixing mechanism 50 and the core stabilizing assembly 22 press against the side of the battery cell to support the battery cell. The glue feeding mechanism 30 clamps the tape 92 and pulls the tape 92 toward the glue pushing assembly 23 to automatically feed the tape 92. When the tape 92 is delivered to the set length, the glue cutting mechanism 40 cuts the tape 92, and the glue pushing assembly 23 pushes the cut tape 92 to the glue applying assembly 21. The glue applying assembly 21 presses one end of the tape 92 against the battery cell, and the battery cell rotates to achieve the purpose of applying the tape 92 to the battery cell, completing the gluing of the battery cell.

[0050] Since the adhesive feeding mechanism 30 delivers the set length of the adhesive tape 92, the adhesive cutting mechanism 40 immediately cuts the adhesive tape 92, eliminating the need to wait for the adhesive tape 92 to be applied to the battery cell for a full circle before cutting. This improves efficiency. Furthermore, after the adhesive tape 92 is cut, the adhesive applying assembly 21 holds the adhesive tape 92 against the battery cell, which rotates to drive the adhesive tape 92 to adhere to the battery cell. Since the cut adhesive tape 92 is applied to the battery cell, the tension of the adhesive tape 92 on the battery cell is small when the battery cell rotates, and thus the wrapping force of the adhesive tape 92 on the battery cell is also small, thus avoiding affecting the internal structure of the battery cell and facilitating the winding needle to remove the core, thereby improving efficiency.

[0051] The battery cell gluing device 100 provided in the embodiment of the present application is compared with the prior art. The battery cell gluing device 100 in the embodiment of the present application clamps and pulls the tape 92 through the glue feeding mechanism 30 to automatically feed the tape 92 to the gluing mechanism 20. The glue cutting mechanism 40 cuts the tape 92 when the glue feeding mechanism 30 feeds the set length, and the core stabilizing component 22 and the core fixing mechanism 50 support the two sides of the battery cell to stabilize the battery cell, and the glue pushing component 23 pushes the tape 92 to the gluing component 21. , so that the glue sticking component 21 can stick the cut tape 92 on the battery cell, realizing automatic glue sticking of the battery cell; since the glue cutting mechanism 40 cuts the tape 92 after the glue feeding mechanism 30 delivers the set length of tape 92, there is no need to wait for the tape 92 to be stuck on the battery cell, which is more efficient; and the glue sticking component 21 sticks the cut tape 92 on the battery cell, reducing the tension of the tape 92 during glue sticking, thereby reducing the wrapping force of the tape 92 on the battery cell, avoiding affecting the internal structure of the battery cell, and also facilitating the winding needle to cut and pull the core, thereby improving efficiency.

[0052] In one embodiment, see Figure 1 and Figure 4The battery cell adhesive laminating device 100 further includes a glue dispensing mechanism 10, which includes a glue dispensing assembly 11 and a guide wheel assembly 12. The glue dispensing assembly 11 is used to pull the adhesive tape 92 out of the adhesive reel 91. The guide wheel assembly 12 guides the adhesive tape 92 pulled out by the glue dispensing assembly 11 into the adhesive feeding mechanism 30, thereby facilitating the delivery of the adhesive tape 92 by the adhesive feeding mechanism 30. It is understood that the adhesive tape 92 on the adhesive reel 91 can also be directly connected to the adhesive feeding mechanism 30. Of course, the adhesive tape 92 can also be supplied to the adhesive feeding mechanism 30 manually or by a robot.

[0053] In one embodiment, see Figure 1 and Figure 4 The debonding component 11 includes a pulling wheel 111 and a debonding driver 112. The pulling wheel 111 resists the adhesive tape 92. The debonding driver 112 is connected to the pulling wheel 111. The debonding driver 112 drives the pulling wheel 111 to move to pull out the adhesive tape 92 in the adhesive disc 91.

[0054] In one embodiment, the glue-opening driver 112 can use a linear driver such as a cylinder or a direct motor. Of course, the glue-opening driver 112 can also use a motor to drive a rocker or a cam to rotate to drive the pulling wheel 111 to move.

[0055] In one embodiment, see Figure 1 and Figure 4 The debonding component 11 also includes a support seat 113, a guide rail 114 and a sliding block 115. The guide rail 114 is installed on the support seat 113, the sliding block 115 is slidably installed on the guide rail 114, and the pulling wheel 111 is installed on the sliding block 115. The debonding driver 112 is connected to the support seat 113, and the debonding driver 112, the guide rail 114 and the sliding block 115 are supported by the support seat 113. The debonding driver 112 drives the sliding block 115 to move along the guide rail 114 to drive the pulling wheel 111 to move along the guide rail 114 to pull out the tape 92.

[0056] In one embodiment, see Figure 4 and Figure 5 The glue discharging mechanism 10 also includes a glue detection component 13, which includes a guide wheel 131, multiple detection pieces 132 and a detector 133. Each detection piece 132 is mounted on the guide wheel 131. The detector 133 is used to sense the detection piece 132. The guide wheel 131 is used to guide the movement of the adhesive tape 92. That is, the adhesive tape 92 passes around the guide wheel 131. When the adhesive tape 92 moves, it can drive the guide wheel 131 to rotate, and then drive the multiple detection pieces 132 to rotate. When each detection piece 132 passes the detector 133, it can be detected by the detector 133 to determine the rotation angle of the guide wheel 131, and then determine the conveying length of the adhesive tape 92.

[0057] In one embodiment, see Figure 1 、 Figure 4 and Figure 5 The guide wheel 131 is provided with textures, and the adhesive side of the tape 92 is wrapped around the guide wheel 131 to reduce the adhesive force between the tape 92 and the guide wheel 131, making it easier for the tape 92 to pull the guide wheel 131 to rotate.

[0058] In one embodiment, the guide wheel group 12 includes two first guide wheels 121, which are arranged on both sides of the pulling wheel 111 to guide the tape 92 to wrap around the pulling wheel 111, increase the wrap angle between the tape 92 and the pulling wheel 111, so that the tape 92 can be better pulled out when the pulling wheel 111 moves.

[0059] In one embodiment, the first guide wheel 121 is provided with textures, and the adhesive side of the tape 92 is wound around the first guide wheel 121, while the non-adhesive side of the tape 92 is wound around the pulling wheel 111 to reduce the adhesion force between the tape 92 and the first guide wheel 121, making it easier for the pulling wheel 111 to pull out the tape 92.

[0060] In one embodiment, the guide wheel assembly 12 further includes two second guide wheels 122 , which are disposed on both sides of the guide wheel 131 , so as to determine the wrap angle of the tape 92 on the guide wheel 131 through the position layout of the two second guide wheels 122 .

[0061] In one embodiment, the guide wheel assembly 12 further includes an intermediate wheel 123 to better guide the movement of the adhesive tape 92 .

[0062] In one embodiment, the glue discharging mechanism 10 further includes a support shaft 14 , and the glue disc 91 is detachably mounted on the support shaft 14 , so that the glue disc 91 is supported by the support shaft 14 , thereby facilitating the installation and replacement of the glue disc 91 .

[0063] In one embodiment, see Figure 6 and Figure 7 The glue-applying assembly 21 includes a glue-applying roller 211, a main bracket 212, and a glue-applying driver 213. The glue-applying roller 211 is rotatably mounted on the main bracket 212. The glue-applying driver 213 is connected to the main bracket 212. The glue-applying roller 211 is used to apply the adhesive tape 92 to the battery cell. The glue-applying driver 213 is used to drive the main bracket 212 to drive the glue-applying roller 211 toward and away from the battery cell. The glue-applying assembly 21 and the glue-pushing assembly 23 are located on opposite sides of the glue-applying roller 211. When in use, the glue-applying driver 213 drives the main bracket 212 to move toward the battery cell, driving the glue-applying roller 211 to press one end of the adhesive tape 92 against the battery cell, thereby applying the adhesive tape 92 to the battery cell when the battery cell rotates. After the adhesive tape 92 is applied to the battery cell, the glue-applying driver 213 drives the main bracket 212 to move away from the battery cell and drives the glue-applying roller 211 away from the battery cell.

[0064] In one embodiment, see Figure 6 and Figure 7 The glue-applying driver 213 can use a linear driver such as a cylinder or a direct motor.

[0065] In one embodiment, the adhesive assembly 21 further includes a first guide rail 214 , and the main bracket 212 is slidably mounted on the first guide rail 214 . The first guide rail 214 supports and guides the movement of the main bracket 212 to ensure smooth movement of the main bracket 212 .

[0066] In one embodiment, the adhesive application assembly 21 further includes a first slider 215, which is slidably mounted on the first guide rail 214. The main bracket 212 is connected to the first slider 215 so that the main bracket 212 is slidably mounted on the first guide rail 214. It is understandable that the main bracket 212 can also be directly mounted on the first guide rail 214.

[0067] In one embodiment, the glue assembly 21 further includes a first support 216 , the first guide rail 214 is mounted on the first support 216 , and the glue driver 213 is mounted on the first support 216 to support the first guide rail 214 and the glue driver 213 to facilitate the installation and use of the glue assembly 21 .

[0068] In one embodiment, see Figure 6 and Figure 7 The core stabilizing assembly 22 includes a pressure roller 221, a support frame 222, and a pressure roller driver 223. The pressure roller 221 is rotatably mounted on the support frame 222. The pressure roller driver 223 is connected to the support frame 222 to drive the support frame 222 toward and away from the battery cell through the pressure roller driver 223, thereby driving the pressure roller 221 toward and away from the battery cell. When the pressure roller 221 needs to press against one side of the battery cell, the pressure roller driver 223 drives the support frame 222 toward the battery cell, thereby driving the pressure roller 221 toward the battery cell until it presses against the battery cell. When the pressure roller 221 needs to leave the battery cell, the pressure roller driver 223 drives the support frame 222 away from the battery cell, thereby driving the pressure roller 221 away from the battery cell.

[0069] In one embodiment, see Figure 6 and Figure 7The support frame 222 is slidably mounted on the main support 212, and the pressure roller driver 223 is mounted on the main support 212. The main support 212 supports the pressure roller 221, the support frame 222, and the pressure roller driver 223. That is, the main support 212 supports the core stabilizing assembly 22, so that when the glue driver 213 drives the main support 212 to move, it can also drive the core stabilizing assembly 22 to move. In this way, the driving stroke of the pressure roller driver 223 can be set to be shorter, thereby reducing the size and volume of the core stabilizing assembly 22 and improving the integration. It is understandable that the core stabilizing assembly 22 can also be provided separately without being connected to the main support 212.

[0070] In one embodiment, see Figure 6 and Figure 7 The core stabilizing assembly 22 also includes a swing frame 224 and an elastic member 225. The swing frame 224 is rotatably mounted on the support frame 222, and the pressure roller 221 is rotatably mounted on the swing frame 224. The elastic member 225 connects the support frame 222 and the swing frame 224, so that the elastic member 225 elastically pulls the swing frame 224 toward one side of the glue-applying roller 211. In this way, when the pressure roller 221 is against the battery cell, the elastic member 225 can drive the pressure roller 221 on the swing frame 224 to elastically press against the battery cell so as to apply glue to the battery cell.

[0071] In one embodiment, the elastic member 225 can be a spring. Of course, the elastic member 225 can also be an elastic pull rope, a spring sheet, etc.

[0072] In one embodiment, a first guide assembly 226 may be provided on the main support 212 to guide the support frame 222 to move on the main support 212. The first guide assembly 226 may be a guide rod, a guide rail, or other assembly.

[0073] In one embodiment, the direction in which the pressure roller driver 223 drives the support frame 222 to move can be the same as the direction in which the glue application driver 213 drives the main support frame 212 to move. Of course, the direction in which the pressure roller driver 223 drives the support frame 222 to move can be different from the direction in which the glue application driver 213 drives the main support frame 212 to move. For example, the direction in which the pressure roller driver 223 drives the support frame 222 to move can intersect with the direction in which the glue application driver 213 drives the main support frame 212 to move.

[0074] In one embodiment, see Figure 6 and Figure 7 The pressure roller driver 223 can use a linear driver such as a cylinder or a direct motor.

[0075] In one embodiment, see Figure 6 and Figure 7The adhesive pushing assembly 23 includes an adhesive pushing block 231 and an adhesive pushing driver 232. The adhesive pushing driver 232 is connected to the adhesive pushing block 231. The adhesive pushing driver 232 drives the adhesive pushing block 231 to move toward and away from the adhesive applying roller 211, so that the adhesive pushing block 231 pushes the adhesive tape 92 to the adhesive applying roller 211, so that the adhesive applying roller 211 can apply the adhesive tape 92 to the battery cell. When the adhesive feeding mechanism 30 drives the adhesive tape 92 to move toward the adhesive pushing block 231, the adhesive pushing driver 232 then drives the adhesive pushing block 231 to move toward the adhesive applying roller 211, so that the adhesive applying roller 211 can apply the adhesive tape 92 to the battery cell. When the adhesive roller 211 presses the adhesive tape 92 against the battery cell, the adhesive pushing driver 232 drives the adhesive pushing block 231 to move away from the adhesive roller 211 so as to push the adhesive tape 92 delivered by the adhesive feeding mechanism 30 to the adhesive roller 211 when the next battery cell is adhesive-applied.

[0076] In one embodiment, see Figure 6 and Figure 7 The adhesive push driver 232 is mounted on the main bracket 212, and the adhesive push block 231 is slidably mounted on the main bracket 212. The main bracket 212 supports the adhesive push driver 232 and the adhesive push block 231, that is, the main bracket 212 supports the adhesive push assembly 23, so that when the adhesive driver 213 drives the main bracket 212 to move, the adhesive push assembly 23 can be driven to move. In this way, the driving stroke of the adhesive push driver 232 can be set to be smaller, thereby reducing the size and volume of the adhesive push assembly 23 and improving the integration. It is understandable that the adhesive push assembly 23 can also be set separately without being connected to the main bracket 212.

[0077] In one embodiment, the direction in which the rubber pushing driver 232 drives the rubber pushing block 231 to move can be the same as the direction in which the rubber applying driver 213 drives the main support 212 to move. Of course, the direction in which the rubber pushing driver 232 drives the rubber pushing block 231 to move can be different from the direction in which the rubber applying driver 213 drives the main support 212 to move, such as the direction in which the rubber pushing driver 232 drives the rubber pushing block 231 to move can intersect with the direction in which the rubber applying driver 213 drives the main support 212 to move.

[0078] In one embodiment, see Figure 6 and Figure 7 The glue pushing driver 232 can use a linear driver such as a cylinder or a direct motor.

[0079] In one embodiment, a second guide assembly 233 may be provided on the main support 212 to guide the rubber pusher 231 to move on the main support 212. The second guide assembly 233 may be a guide rod, a guide rail, or other assembly.

[0080] In one embodiment, see Figure 3 、 Figure 6 and Figure 8The glue feeding mechanism 30 includes a mounting base 33, a glue feeding plate 31, a clamping block 32, a first actuator 34, and a second actuator 35. The glue feeding plate 31 is mounted on the mounting base 33, and the first actuator 34 is mounted on the mounting base 33. The first actuator 34 is connected to the clamping block 32, and the second actuator 35 is connected to the mounting base 33. The first actuator 34 is used to drive the clamping block 32 and the glue feeding plate 31 to cooperate in clamping the adhesive tape 92, and the second actuator 35 is used to drive the mounting base 33 to move toward and away from the glue pushing block 231. During use, the adhesive tape 92 extends between the adhesive feeding plate 31 and the clamping block 32. The first driver 34 drives the clamping block 32 toward the adhesive feeding plate 31 so that the adhesive feeding plate 31 and the clamping block 32 cooperate to clamp the adhesive tape 92. Then, the second driver 35 drives the mounting seat 33 to move toward the adhesive pushing block 231, thereby driving the first driver 34, the adhesive feeding plate 31, and the clamping block 32 to move toward the adhesive pushing block 231. The adhesive tape 92, which is clamped by the adhesive feeding plate 31 and the clamping block 32, is then delivered to the adhesive pushing block 231 so that the adhesive pushing block 231 pushes the adhesive tape 92 to the adhesive applying roller 211. Then, the first driver 34 drives the clamping block 32 away from the adhesive feeding plate 31 to loosen the adhesive tape 92. This allows the adhesive tape 92 to exert less tension on the battery cell during adhesive application, thereby minimizing the impact on the internal structure of the battery cell. Afterwards, the second driver 35 drives the mounting base 33 and drives the first driver 34 , the adhesive feeding plate 31 and the clamping block 32 away from the adhesive pushing block 231 so as to convey the next section of adhesive tape 92 .

[0081] In one embodiment, see Figure 3 、 Figure 6 and Figure 8 The glue feeding mechanism 30 further includes a second guide rail 361 mounted on the mounting base 33. The clamping block 32 is slidably mounted on the second guide rail 361 to guide the clamping block 32 for smooth movement. It is understood that the clamping block 32 can also be supported by a first driver 34. The first driver 34 can be a linear actuator such as a pneumatic cylinder or a direct current motor. Of course, the first driver 34 can also be a rotator, which drives the clamping block 32 to rotate, thereby cooperating with the glue feeding plate 31 to clamp the adhesive tape 92.

[0082] In one embodiment, the glue feeding mechanism 30 further includes a second slider 362, which is mounted on the second guide rail 361. The clamping block 32 is connected to the second slider 362 to facilitate installation and support of the clamping block 32, so that the clamping block 32 can be slidably mounted on the second guide rail 361. Of course, the clamping block 32 can also be directly mounted on the second guide rail 361.

[0083] In one embodiment, the glue feeding mechanism 30 further includes a second support 363 , which is mounted on the mounting base 33 , and the second guide rail 361 is mounted on the second support 363 , so that the second guide rail 361 is supported by the second support 363 to facilitate the installation of the second guide rail 361 .

[0084] In one embodiment, see Figure 3 、 Figure 6 and Figure 8 The glue feeding mechanism 30 further includes a third guide rail 371, and the mounting seat 33 is slidably mounted on the third guide rail 371 to guide the mounting seat 33 to move smoothly through the third guide rail 371. The second driver 35 can use a linear driver such as a cylinder or a direct motor.

[0085] In one embodiment, the glue feeding mechanism 30 further includes a third slider 372, which is mounted on the third guide rail 371. The mounting base 33 is connected to the third slider 372 so that the mounting base 33 can be slidably mounted on the third guide rail 371. Of course, the mounting base 33 can also be directly mounted on the third guide rail 371.

[0086] In one embodiment, the direction in which the second driver 35 drives the mounting seat 33 to move can intersect with the direction in which the adhesive pushing driver 232 drives the adhesive pushing block 231 to move, so that the adhesive feeding mechanism 30 can transfer the adhesive tape 92 to the adhesive pushing block 231. In one embodiment, the direction in which the second driver 35 drives the mounting seat 33 to move can be perpendicular to the direction in which the adhesive pushing driver 232 drives the adhesive pushing block 231 to move, so as to facilitate positioning of the adhesive tape 92 transferred by the adhesive feeding mechanism 30. It is understandable that the direction in which the second driver 35 drives the mounting seat 33 to move can also be arranged at an acute angle or an obtuse angle to the direction in which the adhesive pushing driver 232 drives the adhesive pushing block 231 to move.

[0087] In one embodiment, see Figure 3 、 Figure 6 and Figure 8 The rubber pushing block 231 is provided with a plurality of first push bars 2311 at intervals, and the rubber feeding plate 31 is provided with a plurality of second push bars 311 at intervals. The first push bars 2311 and the second push bars 311 are arranged alternately in space. When the rubber feeding plate 31 moves to the rubber pushing block 231, the plurality of first push bars 2311 cross-fit with the plurality of second push bars 311. The plurality of second push bars 311 are provided on the rubber feeding plate 31 and are arranged at intervals to form a fork-like structure, which can support the rubber tape 92 when it is conveyed. A plurality of first push strips 2311 are provided on the glue pushing block 231, and the plurality of first push strips 2311 are arranged at intervals to form a fork-shaped structure. After the second push strips 311 deliver the adhesive tape 92, the first push strips 2311 are inserted into the gaps between the second push strips 311 to push a section of the adhesive tape 92 on the second push strips 311 toward the glue applying roller 211, so that the glue applying roller 211 can hold the adhesive tape 92 against the battery cell, so that the battery cell can rotate and glue.

[0088] In one embodiment, see Figure 3 、 Figure 6 and Figure 8, an air channel (not shown) is provided in the clamping block 32, and a plurality of air holes 321 are provided on the clamping block 32, each air hole 321 is connected to the air channel, and when the air channel is connected to the air source, the air can be ejected through the air hole 321 to blow the adhesive tape 92 toward the direction of the adhesive pushing block 231. For example, an air hole 321 can be provided on one side of the clamping block 32 close to the adhesive pushing block 231 so as to blow the adhesive tape 92 toward the direction of the adhesive pushing block 231. When the adhesive tape 92 is conveyed by the adhesive feeding plate 31, the adhesive tape 92 is in the position of the adhesive pushing block 231. Between the rubber feeding plate 31 and the clamping block 32, the air hole 321 blows the adhesive tape 92 toward the rubber pushing block 231, so that the adhesive tape 92 is pressed against the rubber feeding plate 31. In this way, when the rubber feeding plate 31 transfers the adhesive tape 92 to the rubber pushing block 231, the rubber pushing block 231 pushes the adhesive tape 92. At this time, the air hole 321 blows the adhesive tape 92 toward the rubber pushing block 231, so that the adhesive tape 92 is pressed against the rubber pushing block 231, so that the rubber pushing block 231 can better push the adhesive tape 92 toward the adhesive roller 211.

[0089] In the above embodiment, when a first push strip 2311 is provided on the rubber pushing block 231 and a second push strip 311 is provided on the rubber feeding plate 31, when the rubber feeding plate 31 conveys the adhesive tape 92, the adhesive tape 92 can be pressed against the second push strip 311. When the first push strip 2311 is inserted into the gap between the second push strips 311, the adhesive tape 92 can be blown against the first push strip 2311 to push the adhesive tape 92 to the adhesive roller 211.

[0090] In one embodiment, a connector 322 is mounted on the clamping block 32, and the connector 322 is connected to the airway. The connector 322 is provided to connect to the air source. It is understood that the air source can also be directly connected to the airway on the clamping block 32.

[0091] In one embodiment, see Figure 1 、 Figure 3 and Figure 9 The rubber cutting mechanism 40 includes a cutter 41, a connecting base 42, and a rubber cutting driver 43. The cutter 41 is mounted on the connecting base 42, which is connected to the rubber cutting driver 43. The rubber cutting driver 43 drives the connecting base 42 to move, thereby driving the cutter 41 to move, thereby cutting the adhesive tape 92 delivered by the rubber feeding mechanism 30. The rubber cutting mechanism 40 has a simple structure and is easy to install and use.

[0092] In one embodiment, the rubber cutting mechanism 40 further includes a fixing seat 44 , and the rubber cutting driver 43 is mounted on the fixing seat 44 to support the rubber cutting driver 43 .

[0093] In one embodiment, the connecting base 42 is slidably mounted on the fixing base 44 to support the connecting base 42 and prevent the cutting drive 43 from bearing the weight of the connecting base 42 and the cutter 41. It is understandable that the connecting base 42 can also be directly supported on the cutting drive 43.

[0094] In one embodiment, a third guide assembly 45 may be provided on the fixing seat 44 to guide the connecting seat 42 to move on the fixing seat 44. The third guide assembly 45 may be a guide rod, a guide rail or other assembly.

[0095] In one embodiment, the cutting drive 43 may use a linear drive such as a cylinder or a direct motor.

[0096] In one embodiment, see Figure 3 、 Figure 6 and Figure 9 The blade 411 of the cutter 41 is serrated. This allows the cutter 41 to partially cut the tape 92 when cutting it, i.e., to create a row of holes in the cut surface. This allows the tape 92 to be completely severed by pulling it during adhesive application. Furthermore, this structure facilitates the release of the tape 92 and movement of the adhesive feeding mechanism 30 to the next position where it is clamped, as the tape 92 is not completely severed when the adhesive roller 211 applies the tape 92 to the battery cell. For example, if the adhesive feeding mechanism 30 includes a adhesive feeding plate 31 and a clamping block 32, when the adhesive feeding plate 31 and the clamping block 32 release the tape 92 and the second driver 35 drives the adhesive feeding plate 31 and the clamping block 32 away from the adhesive pushing block 231, the adhesive feeding plate 31 and the clamping block 32 are not completely severed, allowing the adhesive feeding plate 31 and the clamping block 32 to move to the next position where the adhesive tape 92 is clamped.

[0097] In one embodiment, see Figure 1 、 Figure 2 and Figure 10 The core fixing mechanism 50 includes a supporting roller 51, a sliding frame 52, and a core fixing driver 53. The supporting roller 51 is rotatably mounted on the sliding frame 52. The core fixing driver 53 is connected to the sliding frame 52 to drive the sliding frame 52 toward and away from the battery cell, thereby driving the supporting roller 51 toward and away from the battery cell. When the supporting roller 51 needs to contact one side of the battery cell, the core fixing driver 53 drives the sliding frame 52 toward the battery cell, driving the supporting roller 51 toward the battery cell until it contacts the battery cell. When the supporting roller 51 needs to move away from the battery cell, the core fixing driver 53 drives the sliding frame 52 away from the battery cell, driving the supporting roller 51 away from the battery cell.

[0098] In one embodiment, the core fixing mechanism 50 further includes a fourth guide rail 54, on which the carriage 52 is slidably mounted, so as to guide the carriage 52 to move smoothly. It is understood that the carriage 52 may also be supported by a core fixing drive 53. The core fixing drive 53 may be a linear drive such as a cylinder or a direct current motor.

[0099] In one embodiment, the core fixing mechanism 50 further includes a fourth slider 55, which is mounted on the fourth guide rail 54. The sliding frame 52 is connected to the fourth slider 55 to facilitate the installation and support of the sliding frame 52, so as to facilitate the sliding installation of the sliding frame 52 on the fourth guide rail 54. Of course, the sliding frame 52 can also be directly mounted on the fourth guide rail 54.

[0100] In one embodiment, the core fixing mechanism 50 further includes a positioning seat 56 , and the fourth guide rail 54 is mounted on the positioning seat 56 . The fourth guide rail 54 is supported by the positioning seat 56 , and the core fixing driver 53 can be mounted on the positioning seat 56 for easy installation and use.

[0101] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
