Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an adhesive application device and a battery manufacturing system. Background Technology

[0002] In battery production, after the tabs and adapter plates of a bare cell are ultrasonically welded together, adhesive tape needs to be applied to the welding area, attaching the tape to both sides of the welding area. Currently, a single-sided independent adhesive application method is commonly used. This requires applying adhesive to one side of the welding area first, then transporting the bare cell to a flipping station where it is rotated 180° using flipping equipment, and applying adhesive to the other side of the welding area. However, this adhesive application method requires two sets of adhesive application equipment and an additional flipping mechanism, and its efficiency is low, making it difficult to meet the demands of high-speed battery production. Utility Model Content

[0003] In view of this, the present application aims to provide an adhesive application device to improve the efficiency of adhesive application.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: An adhesive applicator includes a frame, an adhesive supply mechanism, a cutting mechanism, and an adhesive application mechanism mounted on the frame, wherein the adhesive supply mechanism and the adhesive application mechanism are each configured as two oppositely arranged components. The adhesive supply mechanism includes a tape reel for winding the tape, and the cutting mechanism is used to cut the tape unwound from the two tape reels. The adhesive applicator includes a moving unit and a gripping unit connected to the moving unit for gripping the adhesive tape. The two gripping units can be driven by the corresponding moving units to attach the tape to two opposite sides of the bare cell tab welding area.

[0005] Furthermore, the cutting mechanism includes two cutting assemblies corresponding one-to-one with the two tapes; each cutting assembly has two cutting sections arranged at intervals along a preset direction, each cutting section including a first driving section and two blades disposed on the driving end of the first driving section; the two blades are driven by the first driving section to move closer to each other and cut the tapes.

[0006] Furthermore, the cutting mechanism also includes a second drive unit disposed on the frame, both of the two cutting blade assemblies are disposed on the drive end of the second drive unit, and the second drive unit is capable of driving the two cutting blade assemblies away from the tape; and / or, the blades of the two blades are arranged in a V-shape.

[0007] Furthermore, the cutting mechanism also includes a support assembly located between the two cutting assemblies; the support assembly includes support blocks that abut against opposite sides of the two tapes respectively.

[0008] Furthermore, the frame is provided with a tape-pulling mechanism, which includes a first lifting part on the frame and two clamping assemblies on the lifting end of the first lifting part. The clamping assemblies include a clamping drive part and two jaws on the drive end of the clamping drive part. The jaws are driven by the clamping drive part to move closer to each other to clamp the corresponding tape.

[0009] Furthermore, the frame is provided with a pressing mechanism, which is located between the tape reel and the cutting mechanism. The pressing mechanism includes pressing mating parts and pressing drive parts respectively disposed on both sides of the tape, and pressing block disposed on the drive end of the pressing drive part. The pressing block is driven by the pressing drive part to move toward the pressing mating parts, so that the pressing mating parts and the pressing block form a clamping and fixing of the tape.

[0010] Furthermore, the adhesive pressing component includes an adhesive pressing roller rotatably mounted on the frame, and the adhesive pressing roller is located on the adhesive side of the tape.

[0011] Furthermore, the frame is provided with a guide roller group, which includes multiple rollers disposed between the tape reel and the pressing mechanism, and the tape passes around the multiple rollers sequentially along a preset path.

[0012] Furthermore, the moving unit includes a second lifting part, a first translation part disposed on the lifting end of the second lifting part, and a second translation part disposed on the moving end of the first translation part; the gripping unit is disposed on the moving end of the second translation part; and / or, the gripping unit includes a vacuum suction cup connected to an external negative pressure source, the vacuum suction cup being capable of adsorbing the adhesive side of the tape.

[0013] Compared with related technologies, this application has the following advantages: (1) The adhesive applicator described in this application sets up two adhesive supply mechanisms and two adhesive applicator mechanisms arranged in opposite directions. The cutting mechanism can cut the adhesive tape from the two tape reels and drive the two gripping units to the corresponding moving units, so as to stick the adhesive tape on both sides of the bare battery cell tab welding area. This realizes the synchronous application of adhesive to both sides of the welding area, reduces the time consumption of single-side step-by-step adhesive application, and improves the work efficiency of the adhesive application process.

[0014] (2) By setting a cutting assembly and setting two cutting parts at the same time, two tapes can be cut at the same time and the two tapes can be cut to a preset length. Furthermore, the first driving part drives the two blades to approach each other and cut the blades, which has a better cutting efficiency and thus improves the efficiency of applying adhesive.

[0015] (3) By setting the second drive unit, the cutter assembly can be driven to retract in the non-cutting state to prevent the cutter assembly from affecting the tape pulling operation or causing interference during tape replacement. In addition, by arranging the blades of the two blades in a V-shape, the cutting effect on the tape can be improved, preventing the tape edges from turning outward or wrinkling, and avoiding the tape shape from affecting the adhesive application effect.

[0016] (4) By setting up the support components, the support blocks can be used to support the tape, preventing it from shifting when the gripping unit grips the tape, thus facilitating the gripping unit to grip the cut tape.

[0017] (5) By setting the clamping components, the two jaws in the clamping components can clamp the tape, and under the drive of the first lifting part, the clamping components can pull the tape to the cutting mechanism to realize the conveying of the tape to the cutting mechanism. At the same time, both clamping components are set on the first lifting part, which can ensure that the length of the two tapes pulled is consistent, and avoid length deviation from affecting the subsequent cutting and adhesive application operations.

[0018] (6) By setting up the adhesive pressing mechanism, the adhesive pressing drive unit drives the adhesive pressing block to move towards the adhesive pressing mating part to clamp and fix the tape. This can keep the tape taut during the tape cutting process and avoid the tape slack affecting the tape cutting effect.

[0019] (7) By setting the pressure roller, the characteristics of the pressure roller rotation can be taken advantage of, reducing the friction and adhesion between the pressure roller and the adhesive side of the tape, and avoiding the adhesive layer from being damaged by friction and affecting the adhesion.

[0020] (8) By setting the guide roller group, the belt can be routed around multiple rollers, which can adjust the tension of the belt, avoid belt deviation, slack and wrinkles, and improve the smoothness of belt conveying.

[0021] (9) Through the coordinated arrangement of the second lifting part, the first translation part, and the second translation part, the moving unit can drive the gripping unit to move in multiple directions, so that the gripping unit can attach the tape to the battery cell. At the same time, it can adapt to different adhesive application positions and has good versatility. Meanwhile, the gripping unit adopts a vacuum suction cup, which can adsorb the adhesive side of the tape, ensuring the gripping effect while ensuring the flatness of the tape, so as to facilitate the application of adhesive.

[0022] Another object of this application is to provide a battery production system having the adhesive application device described above.

[0023] The battery production system described in this application and / or the adhesive application device described above have the same technical effects as related technologies, and will not be described in detail here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides an adhesive applicator.

[0032] In related technologies, a single-sided independent adhesive application method is typically used. This requires first applying adhesive to one side of the welding area, then transporting the bare cell to a flipping station where the cell is flipped 180° using a flipping device, and then applying adhesive to the other side of the welding area. However, this adhesive application method requires two sets of adhesive application equipment and an additional flipping mechanism, and its efficiency is low, making it difficult to meet the demands of high-speed battery production.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the adhesive applicator in this embodiment combines... Figure 1 As shown, the overall design includes a frame 1, and a glue supply mechanism, a cutting mechanism 3 and a glue application mechanism mounted on the frame 1.

[0034] The adhesive supply mechanism and the adhesive application mechanism are both configured as two oppositely arranged units. The adhesive supply mechanism includes a tape reel 2 for winding the tape, and a cutting mechanism 3 for cutting the tape unwound from the two tape reels 2. The adhesive application mechanism includes a moving unit 4 and a moving end connected to the moving unit 4 for gripping the tape. The two gripping units 5 can be driven by their corresponding moving units 4 to apply the tape to two opposite sides of the tab welding area of ​​the bare battery cell 8.

[0035] Therefore, by setting up two glue supply mechanisms and two glue application mechanisms arranged in opposite directions, the cutting mechanism 3 can cut the glue from the two tape reels 2, and drive the two gripping units 5 to the corresponding moving units 4, so as to stick the glue to the two opposite sides of the tab welding area of ​​the bare cell 8. This achieves synchronous glue application on both sides of the welding area, reduces the time consumption of single-sided step glue application, and improves the work efficiency of the glue application process, thereby helping to improve the overall production efficiency of the battery.

[0036] Based on the above overview, specifically, the adhesive applicator of this embodiment can simultaneously apply adhesive to both sides of the welding area. Compared with related technologies that use multiple adhesive applicators and flipping devices, it can also reduce equipment costs and maintenance costs.

[0037] In addition, the frame 1 in this embodiment includes a base 101, a first bracket 102 and a second bracket 103 disposed on the base 101. The first bracket 102 is provided with a glue supply mechanism and a cutting mechanism 3, and the second bracket 103 is provided with a glue application mechanism.

[0038] Tape reels 2 are located on top of the first support 102, and each tape supply mechanism has two tape reels 2, one as the main tape reel 2 and the other as the spare tape reel 2, to facilitate tape replenishment and replacement. Meanwhile, the cutting mechanism 3 is located below the two supply mechanisms.

[0039] In some of the exemplary implementations, combined with Figure 5 As shown, the cutting mechanism 3 includes two cutting assemblies 3a corresponding to two pieces of tape. Each cutting assembly 3a has two cutting sections 301 arranged at intervals along a predetermined direction. Each cutting section 301 includes a first driving section 3011 and two blades 3012 disposed on the driving end of the first driving section 3011. The two blades 3012 are driven by the first driving section 3011 to move closer together and cut the tape.

[0040] By setting the cutter assembly 3a and simultaneously providing two cutter sections 301, two tapes can be cut simultaneously to a preset length. Furthermore, the first drive section 3011 drives the two blades 3012 to approach each other and cut the tapes, resulting in good cutting efficiency and improved adhesive application efficiency. In specific implementation, the preset direction is the extension direction of the tape.

[0041] In some exemplary embodiments, the cutting mechanism 3 further includes a second drive unit 302 disposed on the frame 1, with two cutter assemblies 3a disposed on the drive end of the second drive unit 302, and the second drive unit 302 is capable of driving the two cutter assemblies 3a away from the tape.

[0042] By providing the second drive unit 302, the cutter assembly 3a can be driven to retract in the non-cutting state to avoid the clamping assembly in the adhesive pulling mechanism 6 described below, so as to prevent the cutter assembly 3a from affecting the adhesive pulling operation of the tape or causing interference during tape replacement.

[0043] Meanwhile, in some exemplary embodiments, the blades of the two blades 3012 are arranged in a V-shape, so that the cutting path of the V-shaped blades extends along the width of the tape. The two blades 3012 can gradually cut from one side of the tape to the other side, improving cutting efficiency and thus improving the cutting effect on the tape. This prevents the tape edges from turning outward or wrinkling, and avoids affecting the adhesive application effect due to poor tape shape.

[0044] In some exemplary embodiments, the cutting mechanism 3 further includes a support assembly located between the two cutting blade assemblies 3a. The support assembly includes support blocks 303 that abut against opposite sides of the two tapes. In a specific embodiment, the support blocks 303 are also located between the two cutting blades 301.

[0045] By providing a support component, the support block 303 can support the tape, preventing it from shifting when the gripping unit 5 grips the tape, thus facilitating the gripping unit 5 to grip the cut tape. In a specific implementation, the support component is located on the drive end of the second drive unit 302 and is driven by the second drive unit 302 to move with the cutter assembly 3a.

[0046] In some of the exemplary implementations, combined with Figure 2 , Figure 4 As shown, the frame 1 is provided with a tape-pulling mechanism 6. The tape-pulling mechanism 6 includes a first lifting part 601 provided on the frame 1, and two clamping assemblies provided on the lifting end of the first lifting part 601. The clamping assemblies include a clamping drive part 602, and two grippers 603 provided on the drive end of the clamping drive part 602. The grippers 603 are driven by the clamping drive part 602 to move closer to each other to clamp the corresponding tape.

[0047] By configuring the clamping components, the two grippers 603 in the clamping components can clamp the tape, and under the drive of the first lifting part 601, they can pull the tape to the cutting mechanism 3, thereby realizing the conveying of the tape to the cutting mechanism 3. At the same time, both clamping components are located on the first lifting part 601, which can ensure that the two tapes are pulled to the same length, avoiding length deviation that would affect subsequent cutting and adhesive application operations.

[0048] In a specific implementation, the first support 102 of this embodiment is provided with a vertically arranged slide rail, and the first lifting part 601 includes a lifting plate 6011 slidably arranged on the slide rail, and a synchronous belt 6013 assembly arranged on the first support 102. The synchronous belt 6013 assembly includes two pulleys 6012 that are driven to rotate and are arranged at intervals along a preset direction, and a synchronous belt 6013 wound on the pulleys 6012. The lifting plate 6011 is provided with a fixing block for connecting the synchronous belt 6013.

[0049] When the pulley 6012 is driven to rotate, the synchronous belt 6013 can drive the lifting plate 6011 to rise and fall through the fixed block. At this time, the first lifting part 601 acts as a lifting mechanism for the synchronous belt 6013 to drive the clamping component to rise and fall. Of course, the first lifting part 601 in this embodiment can also adopt other conventional lifting mechanisms known to those skilled in the art, as long as they can drive the clamping component to rise and fall.

[0050] In some of the exemplary implementations, combined with Figure 2 , Figure 3 As shown, a tape pressing mechanism 7 is provided on the frame 1, and the tape pressing mechanism 7 is located between the tape reel 2 and the cutting mechanism 3. The tape pressing mechanism 7 includes tape pressing mating parts and a tape pressing drive part 702 respectively disposed on both sides of the tape, and a tape pressing block 703 disposed on the drive end of the tape pressing drive part 702. The tape pressing block 703 is driven by the tape pressing drive part 702 to move towards the tape pressing mating parts, so that the tape pressing mating parts and the tape pressing block 703 form a clamping and fixing mechanism for the tape.

[0051] By setting up the adhesive pressing mechanism 7, the adhesive pressing drive unit 702 drives the adhesive pressing block 703 to move toward the adhesive pressing mating part to clamp and fix the tape. This can keep the tape taut during the tape cutting process and avoid the tape slack affecting the tape cutting effect.

[0052] Furthermore, in some exemplary embodiments, the pressure-adhesive mating component includes a pressure roller 701 rotatably mounted on the frame 1, and the pressure roller 701 is located on the adhesive side of the tape. It is understood that the contact area between the pressure roller 701 and the tape is small, and the pressure roller 701 can rotate freely. When the tape adheres to the pressure roller, even if the tape is pulled, the pressure roller 701 can roll along with the movement of the tape, avoiding significant frictional adhesion between the adhesive side of the tape and the pressure roller. Therefore, by utilizing the rotational characteristics of the pressure roller 701, friction and adhesion between the pressure roller 701 and the adhesive side of the tape can be reduced, preventing the adhesive layer from being damaged by friction and affecting its tackiness.

[0053] In some exemplary embodiments, the frame 1 is provided with a guide roller group, which includes multiple rollers 201 disposed between the tape reel 2 and the tape pressing mechanism 7. The tape passes around the multiple rollers 201 sequentially along a preset path. By setting the guide roller group so that the tape passes around the multiple rollers 201, the tension of the tape can be adjusted, avoiding tape deviation, slack, and wrinkles, thereby improving the smoothness of tape conveying.

[0054] In some of the exemplary implementations, combined with Figure 6 , Figure 7 As shown, the moving unit 4 includes a second lifting part 401, a first translation part 402 disposed on the lifting end of the second lifting part 401, and a second translation part 403 disposed on the moving end of the first translation part 402. The second lifting part 401 is disposed on the second support 103, and the gripping unit 5 is disposed on the moving end of the second translation part 403.

[0055] The coordinated arrangement of the second lifting part 401, the first translation part 402, and the second translation part 403 enables the moving unit 4 to drive the gripping unit 5 to move in multiple directions, so that the gripping unit 5 can attach the tape to the battery cell. At the same time, it can adapt to different adhesive application positions and has good versatility.

[0056] Meanwhile, in some exemplary embodiments, the gripping unit 5 includes a vacuum suction cup 501 connected to an external negative pressure source, which is capable of adsorbing the adhesive side of the tape. The gripping unit 5 uses a vacuum suction cup 501, which can adsorb the adhesive side of the tape, ensuring both gripping effectiveness and tape flatness for easy application.

[0057] In specific implementation, the two first translation mechanisms in the two moving units 4 of this embodiment can preferably be arranged on the same second lifting part 401. Of course, two second lifting parts 401 can also be arranged to drive the two first translation mechanisms to rise and fall respectively.

[0058] In addition, the gripping unit 5 in this embodiment also includes a variable pitch assembly. The variable pitch drive unit 502 has a similar structure to the first drive unit 3011, with two drive ends that move synchronously and in opposite directions. Both drive ends are provided with the aforementioned vacuum suction cups 501. The variable pitch drive unit 502 can drive the two vacuum suction cups 501 to move away from or closer to each other so as to attach the tape to the designated position of the battery cell, that is, the two welding areas corresponding to the positive and negative electrodes.

[0059] Understandably, as a specific implementation, the adhesive-pulling mechanism 6 can pull out a sufficient length of adhesive tape, creating a certain length of tape between the two cutting sections 301, and also creating a certain length of tape between the lower cutting section 301 and the adhesive-pulling mechanism 6. Thus, after cutting the tape, a single tape can be cut into two segments. At this time, the two vacuum suction cups 501 can respectively pick up the two tape segments to facilitate applying adhesive to the soldering areas of the positive and negative tabs of the bare battery cell 8.

[0060] Furthermore, the first driving unit 3011, the second driving unit 302, the second lifting unit 401, the clamping driving unit 602, the adhesive pressing driving unit 702, the first translation unit 402, and the second translation unit 403 in this embodiment can all adopt conventional driving mechanisms well known to those skilled in the art, such as linear modules, telescopic cylinders, and pneumatic cylinders, which can drive the corresponding components to move in the corresponding direction.

[0061] It is worth mentioning that the second translation section 403 in this embodiment includes two cylinders. The cylinder body of one cylinder is connected to the drive end of the first translation section 402, and the piston rod of the first cylinder is connected to the cylinder body of the second cylinder. A gripping unit 5 is provided on the piston rod of the second cylinder. This arrangement not only ensures the driving formation of the second translation section 403, but also reduces the length of the second translation section 403, thus reducing the space occupied.

[0062] It is worth noting that, regarding the adhesive applicator of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still shown in the figure.

[0063] The adhesive applicator in this embodiment includes a frame 1, and an adhesive supply mechanism, a cutting mechanism 3 and an adhesive applicator mounted on the frame 1.

[0064] The adhesive supply mechanism and the adhesive application mechanism are both configured as two oppositely arranged units. The adhesive supply mechanism includes a tape reel 2 for winding the tape, and a cutting mechanism 3 for cutting the tape unwound from the two tape reels 2. The adhesive application mechanism includes a moving unit 4 and a moving end connected to the moving unit 4 for gripping the tape. The two gripping units 5 can be driven by their corresponding moving units 4 to apply the tape to two opposite sides of the tab welding area of ​​the bare battery cell 8.

[0065] Specifically, the frame 1 includes a base 101, a first support 102 and a second support 103 mounted on the base 101. The first support 102 is equipped with a glue supply mechanism and a cutting mechanism 3, and the second support 103 is equipped with a glue application mechanism. A tape reel 2 is located on top of the first support 102, and each glue supply mechanism has two tape reels 2: one is a commonly used tape reel, and the other is a spare tape reel, facilitating tape replenishment and replacement. Meanwhile, the cutting mechanism 3 is located below the two supply mechanisms.

[0066] Furthermore, the cutting mechanism 3 includes two cutting assemblies 3a corresponding to two pieces of tape. Each cutting assembly 3a has two cutting sections 301 spaced apart along a predetermined direction. Each cutting section 301 includes a first drive section 3011 and two blades 3012 disposed on the drive end of the first drive section 3011. The two blades 3012 are driven by the first drive section 3011 to move closer together and cut the tape. The cutting mechanism 3 also includes a second drive section 302 disposed on the frame 1. Both cutting assemblies 3a are disposed on the drive end of the second drive section 302, and the second drive section 302 can drive the two cutting assemblies 3a away from the tape. Simultaneously, the cutting edges of the two blades 3012 are arranged in a V-shape.

[0067] In addition, the cutting mechanism 3 also includes a support assembly located between the two cutting blade assemblies 3a. The support assembly includes support blocks 303 that abut against opposite sides of the two tapes. The support blocks 303 are also located between the two cutting blade sections 301.

[0068] Furthermore, the frame 1 is provided with a tape-pulling mechanism 6, which includes a first lifting part 601 on the frame 1 and two clamping assemblies on the lifting end of the first lifting part 601. The clamping assemblies include a clamping drive part 602 and two grippers 603 on the drive end of the clamping drive part 602. The grippers 603 are driven by the clamping drive part 602 to move closer to each other to clamp the corresponding tape. The first support 102 is provided with a vertically arranged slide rail, and the first lifting part 601 includes a lifting plate 6011 slidably arranged on the slide rail and a synchronous belt 6013 assembly arranged on the first support 102. The synchronous belt 6013 assembly includes two pulleys 6012 that are driven to rotate and are spaced apart along a preset direction, and a synchronous belt 6013 wound on the pulleys 6012. The lifting plate 6011 is provided with a fixing block for connecting the synchronous belt 6013.

[0069] Furthermore, the frame 1 is equipped with a glue-pressing mechanism 7, which is located between the tape reel 2 and the cutting mechanism 3. The glue-pressing mechanism 7 includes glue-pressing mating parts and a glue-pressing drive unit 702 respectively disposed on both sides of the tape, and a glue-pressing block 703 disposed on the drive end of the glue-pressing drive unit 702. The glue-pressing block 703 is driven by the glue-pressing drive unit 702 to move towards the glue-pressing mating parts, so that the glue-pressing mating parts and the glue-pressing block 703 form a clamping and fixing of the tape. The glue-pressing mating parts include a glue-pressing roller 701 rotatably disposed on the frame 1, and the glue-pressing roller 701 is located on the glue-adhesive side of the tape.

[0070] Meanwhile, the frame 1 is equipped with a guide roller assembly, which includes multiple rollers 201 disposed between the tape reel 2 and the pressing mechanism 7.

The pitch-changing drive unit 502 can drive the two vacuum suction cups 501 to move away from or closer to each other, so as to attach the tape to the designated position of the battery cell, that is, the two welding areas corresponding to the positive and negative tabs.

[0072] In the preferred embodiment of the above adhesive applicator, the specific configuration and arrangement of the adhesive supply mechanism, the cutting mechanism 3 and the adhesive applicator can still be referred to the descriptions in the above exemplary embodiments.
