Description

Technical Field

[0001] This application relates to the field of battery cell manufacturing technology, and in particular to a battery cell adhesive bonding equipment and a battery production system. Background Technology

[0002] During battery cell production, sealing tape needs to be applied to the Mylar film covering the cell. Typically, multiple layers of sealing tape are applied to a cell, with small gaps between each layer. Currently, the tape-applying mechanism in battery production systems can only apply one layer of tape to a cell at a time. After one layer is applied, the cell needs to be transferred to the next tape-applying mechanism for re-application.

[0003] However, the above-mentioned adhesive application process requires setting up multiple adhesive application mechanisms to apply adhesive to the battery cells separately, which not only increases the cost of the equipment, but also results in low efficiency in applying adhesive to the battery cells. In addition, it is not convenient to adjust the spacing between the adhesive tapes, and the versatility is poor. Utility Model Content

[0004] In view of this, this application aims to provide a battery cell adhesive application device to improve the efficiency of battery cell adhesive application and enhance its versatility.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A battery cell adhesive application device includes an adhesive application mechanism for applying adhesive tape to a battery cell. The adhesive application mechanism includes a base, a plurality of adhesive application components slidably disposed on the base, and a locking mechanism disposed on each of the adhesive application components. The plurality of adhesive application components are arranged along the X-axis direction, and each of the adhesive application components can be driven to slide along the X-axis direction; The locking mechanism can be operated to restrict the position of the corresponding adhesive component relative to the base.

[0006] Furthermore, the base is provided with a guide rod extending along the X-axis direction, and the adhesive application assembly is slidably passed through the guide rod; the locking mechanism includes a locking member provided on the adhesive application assembly, and the locking member can be operated to clamp the guide rod.

[0007] Furthermore, the adhesive application assembly includes a frame, a tape reel, a tape dispensing roller assembly, and an adhesive application plate disposed on the frame; the tape dispensing roller assembly is used to guide the tape in the tape reel to be conveyed to the adhesive application plate, and the tape dispensing roller assembly includes multiple rollers, and the tape passes around the multiple rollers sequentially along a preset path.

[0008] Furthermore, the adhesive application assembly includes a cutting unit; the cutting unit includes a first drive unit disposed on the frame and a cutter connected to the drive end of the first drive unit; the end of the adhesive application plate is provided with a channel through which the cutter passes, and the cutter can be driven to extend out from the channel to cut the adhesive tape.

[0009] Furthermore, the adhesive application assembly includes a pressing unit; the pressing unit includes a second drive unit disposed on the frame, and a pressing head connected to the drive end of the second drive unit, the pressing head being driven to press the adhesive tape tightly against the top of the adhesive application plate.

[0010] Furthermore, the adhesive application assembly includes an adhesive removal unit; the adhesive removal unit includes a cylinder and a slider slidably disposed on the frame and connected to the piston rod of the cylinder; the slider is provided with at least one of the plurality of rollers, and the rollers are driven to slide to change the extension length of the adhesive tape in the preset path.

[0011] Furthermore, it also includes a moving mechanism, the moving end of which is connected to the adhesive applicator; the adhesive applicator can be driven by the moving mechanism to move along at least one of the Y-axis and Z-axis directions, and the X-axis, Y-axis and Z-axis directions are perpendicular to each other.

[0012] Furthermore, the moving mechanism includes a translation mechanism and a lifting mechanism; the translation mechanism includes a slide table slidably mounted on a mounting platform, and a translation drive unit mounted on the slide table for driving the slide table to move; the lifting mechanism includes a lead screw nut mounted on the slide table, a lifting lead screw screw screwed to the lead screw nut, and a drive motor for driving the lifting lead screw to rotate, and the top of the lifting lead screw is rotatably connected to the base.

[0013] Compared with related technologies, this application has the following advantages: (1) The battery cell adhesive application equipment described in this application is configured with multiple adhesive application components and a locking mechanism. The multiple adhesive application components can slide on the base and lock in position, which can not only apply multiple tapes to the battery cell at the same time, but also change the spacing between adjacent adhesive application components, thereby adjusting the adhesive spacing on the battery cell. This improves the working efficiency of applying adhesive to the battery cell, and can also adapt to battery cells of different sizes or adhesive application positions, thereby improving versatility.

[0014] (2) By setting the guide rod, the sliding of the adhesive component can be accurately guided, and by operating the locking part, the guide rod can be tightened, which can limit the sliding of the adhesive component relative to the guide rod, so that the adhesive component and the guide rod are firmly connected, further improving the reliability of the position restriction of the adhesive component, and has the advantages of simple structure and convenient operation.

[0015] (3) By setting up the tape reel and the adhesive plate, the tape reel can provide tape to the adhesive plate for adhesive application.

[0018] (6) By setting the de-adhesion unit, the roller on the slider can be driven to move on the frame, thereby adjusting the tension of the tape and ensuring stability during the tape application process. At the same time, after replacing the tape reel, the tape is pulled out of the tape reel by the movement of the roller, thereby realizing the de-adhesion process, which increases the free length of the tape and helps to prevent the tape from sticking back.

[0019] (7) By setting a moving mechanism to drive the entire adhesive applicator to move, the adhesive applicator plate of the adhesive applicator can move along the outline of the area to be adhesiveped on the battery cell, so as to attach the tape to the battery cell. At the same time, the adhesive applicator is driven to move, which can adapt to battery cells of different sizes and adhesive application requirements at different positions on the battery cell, thereby improving versatility.

[0020] (8) By setting up the translation mechanism, the slide can be moved by the translation drive unit, providing precise guidance and power for the translation of the adhesive applicator along the Y-axis.

[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 a battery cell 9 adhesive bonding device.

[0032] In related technologies, the adhesive application mechanism in the battery production system can only apply one layer of adhesive tape to the battery cell 9 at a time. After applying one layer of tape, the battery cell 9 needs to be transferred to the next adhesive application mechanism at the next workstation for another application of adhesive tape.

[0033] However, in the above-mentioned adhesive application process, multiple adhesive application mechanisms are required to apply adhesive to the battery cell 9 separately. This not only increases the cost of the equipment but also results in low efficiency in applying adhesive to the battery cell 9. Furthermore, it is not convenient to adjust the spacing between the adhesive tapes, and the versatility is poor.

[0034] In view of this, in order to overcome the shortcomings of the related technology, the battery cell 9 adhesive bonding equipment in this embodiment combines... Figure 1 , Figure 2 As shown, the overall design includes an adhesive applicator for applying tape to the battery cell 9.

[0035] The adhesive application mechanism includes a base 1, a plurality of adhesive application components 2 slidably disposed on the base 1, and a locking mechanism disposed on each adhesive application component 2. The plurality of adhesive application components 2 are arranged along the X-axis direction, and each adhesive application component 2 can be driven to slide along the X-axis direction. The locking mechanism can be operated to restrict the position of the corresponding adhesive application component 2 relative to the base 1.

[0036] Therefore, by cooperating with multiple adhesive application components 2 and locking mechanism, the multiple adhesive application components 2 can slide and lock their positions on the base 1, which not only allows multiple tapes to be applied to the battery cell 9 at the same time, but also allows the spacing between adjacent adhesive application components 2 to be changed, thereby adjusting the adhesive application spacing on the battery cell 9. This improves the efficiency of applying adhesive to the battery cell 9, and at the same time, it can adapt to battery cells 9 of different sizes or adhesive application position requirements, thus improving versatility.

[0037] Based on the above general description, specifically, in some exemplary embodiments, the base 1 is provided with a guide rod 101 extending along the X-axis, and the adhesive application assembly 2 slides through the guide rod 101. The locking mechanism includes a locking member 3 provided on the adhesive application assembly 2, which can be operated to clamp the guide rod 101.

[0038] By setting the guide rod 101, precise guidance can be provided for the sliding of the adhesive application component 2. By operating the locking member 3 to tighten the guide rod 101, the sliding of the adhesive application component 2 relative to the guide rod 101 can be restricted, so that the adhesive application component 2 and the guide rod 101 are firmly connected, further improving the reliability of the position restriction of the adhesive application component 2, and has the advantages of simple structure and convenient operation.

[0039] In a specific implementation, the base 1 of this embodiment is provided with a first slide rail 102, which extends along the X-axis direction, and the adhesive application component 2 is slidably disposed on the first slide rail 102. In addition, a fixed adhesive application component 2a is fixedly connected to the base 1 of this embodiment. The structure of the fixed adhesive application component 2a is the same as the rest of the adhesive application mechanism slidably disposed on the base 1. The guide rod 101 is fixedly connected to the fixed adhesive application component 2a, and the fixed connection base can serve as the connection base between the guide rod 101 and the base 1.

[0040] Furthermore, the locking element 3 in this embodiment is a conventional quick-release clamp well-known to those skilled in the art. When locked, the clamp can tighten the guide rod 101. Of course, the locking element 3 can also adopt other conventional structures that can clamp and fix the guide rod 101, thereby restricting the sliding of the adhesive application assembly 2.

[0041] Combination Figure 4 As shown, in some exemplary embodiments, the adhesive application assembly 2 includes a frame 201, a tape reel 202, a tape dispensing roller assembly, and an adhesive application plate 203 disposed on the frame 201. The tape dispensing roller assembly guides the tape in the tape reel 202 to the adhesive application plate 203, and the tape dispensing roller assembly includes a plurality of rollers 204, which pass sequentially around the plurality of rollers 204 along a preset path.

[0042] With the tape reel 202 and the adhesive plate 203, the tape reel 202 can supply tape to the adhesive plate 203 for adhesive application. At the same time, the tape feeding roller group can guide the tape to be conveyed to the adhesive plate 203. The tape passes around multiple rollers 204, which can adjust the tension of the tape and prevent the tape from deviating, loosening and wrinkling.

[0043] In this embodiment, the frame 201 is slidably mounted on the first slide rail 102 and slidably passes through the guide rod 101. The adhesive application plate 203 is located on the side of the frame 201 near the battery cell 9 and extends towards the battery cell 9 along the Y-axis. The adhesive tape is conveyed to the top of the adhesive application plate 203.

[0044] During the adhesive application process, the adhesive application plate 203 is moved to the bottom of the battery cell 9, pressing the adhesive tape onto the bottom of the battery cell 9. Then, the adhesive application plate 203 retracts along the Y-axis to further press the tape until the end of the adhesive application plate 203 is aligned with the side of the battery cell 9. Next, the adhesive application plate 203 moves along the Z-axis, pressing the tape onto the side of the battery cell 9 until the bottom of the adhesive application plate 203 is flush with the top of the battery cell 9. Finally, the adhesive application plate 203 moves towards the battery cell 9 along the Y-axis, pressing the tape onto the top of the battery cell 9, and then returns to its original position. This process attaches the tape to the bottom, sides, and top of the battery cell 9, completing the adhesive application process for the battery cell 9.

[0045] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some exemplary embodiments, the adhesive application assembly 2 includes a cutting unit 205. The cutting unit 205 includes a first drive unit 2051 disposed on the frame 201, and a cutter 2052 connected to the drive end of the first drive unit 2051. The end of the adhesive application plate 203 is provided with a channel 2031 through which the cutter 2052 passes, and the cutter 2052 can be driven to extend out of the channel 2031 to cut the adhesive tape.

[0046] The cutting unit 205, utilizing the first drive unit 2051 and the cutter 2052, automatically completes the tape cutting action without manual operation, improving the automation and efficiency of the tape application process. Simultaneously, the channel 2031 provides a guide for the cutter 2052, ensuring that the cutter moves along a preset path to cut the tape, thus guaranteeing the reliability of the cutting unit 205. Furthermore, it ensures that sufficient length of tape remains on the application plate 203 for the next application.

[0047] In specific implementation, the cutter 2052 and the channel 2031 of this embodiment extend along the Y-axis direction. The first drive unit 2051 of this embodiment is a telescopic cylinder well known to those skilled in the art. This telescopic cylinder is mounted on the frame 201 and located on one side of the adhesive plate 203. Alternatively, other conventional linear drive mechanisms can be used, as long as they can drive the cutter 2052 to move along the Y-axis direction.

[0048] In some exemplary embodiments, the adhesive application assembly 2 includes a pressing unit 206. The pressing unit 206 includes a second drive section 2061 disposed on the frame 201, and a pressing head connected to the drive end of the second drive section 2061, the pressing head being driven to press the adhesive tape tightly onto the top of the adhesive application plate 203.

[0049] With the setting of the pressing unit 206, the pressing head can be driven by the second driving part 2061 to press the tape tightly onto the top of the adhesive plate 203, so as to prevent the tape from falling off the adhesive plate 203 during the movement of the adhesive applicator.

[0050] In specific implementation, the second drive unit 2061 of this embodiment is a telescopic cylinder well known to those skilled in the art, or other conventional linear drive mechanisms can be used to drive the cutter 2052 to move along the Y-axis direction.

[0051] In some exemplary embodiments, the adhesive application assembly 2 includes an adhesive release unit 207. The adhesive release unit 207 includes a cylinder 2071 and a slider 2072 slidably mounted on a frame 201 and connected to the piston rod of the cylinder 2071. The slider 2072 is provided with at least one of a plurality of rollers 204, which are driven to slide to change the extension length of the adhesive tape in a preset path.

[0052] After replacing the tape reel 202, the distance between the roller 204 on the slide rail and the adjacent roller 204 fixed on the frame 201 is closest. This facilitates the sequential winding of the tape on the tape reel 202 onto each roller 204, and stretches one end of the tape onto the adhesive plate 203. Subsequently, the pressure head 2062 is driven to press the tape, and the cylinder 2071 drives the roller 204 on the slider 2072 to move, allowing the roller 204 to stretch the tape, thereby pulling the tape further out of the tape reel 202. This achieves the unsealing of the tape reel 202. Through the unsealing process, the free length of the tape can be increased, and it is beneficial to prevent the tape from sticking back.

[0053] With the setting of the tape release unit 207, the roller 204 on the slider 2072 can be driven to move on the frame 201, thereby adjusting the tension of the tape and ensuring stability during the tape application process. At the same time, after replacing the tape reel 202, the movement of the roller 204 is used to pull the tape out of the tape reel 202, realizing the tape release process, thereby increasing the free length of the tape and helping to prevent the tape from sticking back.

[0054] In a specific implementation, the frame 201 of this embodiment is provided with a second slide rail 2073. The second slide rail 2073 can guide the slider 2072 to slide, thereby improving the smoothness of the roller 204 when it moves and preventing the tape from being torn.

[0055] Combination Figure 2 , Figure 3 As shown, in some exemplary embodiments, the cell 9 adhesive applicator further includes a moving mechanism, the moving end of which is connected to the adhesive applicator. The adhesive applicator can be driven by the moving mechanism to move along at least one of the Y-axis and Z-axis directions, and the X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0056] By setting a moving mechanism to drive the entire adhesive application mechanism to move, the adhesive application plate 203 of the adhesive application mechanism can move along the contour of the area to be adhesiveped on the battery cell 9, so as to attach the tape to the battery cell 9. At the same time, the adhesive application mechanism is driven to move, which can adapt to battery cells 9 of different sizes and adhesive application needs at different positions on the battery cell 9, thereby improving versatility.

[0057] In practical implementation, the mounting platform of this embodiment is equipped with two moving mechanisms, each with an adhesive application mechanism. One adhesive application mechanism serves as the primary adhesive application mechanism, while the other serves as a backup adhesive application mechanism, thereby improving the redundancy of the adhesive application equipment for this battery cell 9.

[0058] In some exemplary embodiments, the moving mechanism includes a translation mechanism and a lifting mechanism. The translation mechanism includes a slide 5 slidably mounted on a mounting platform 4, and a translation drive unit mounted on the slide 5 for driving the slide 5 to move. The lifting mechanism includes a lead screw nut 501 mounted on the slide 5, a lifting lead screw 6 screwed to the lead screw nut 501, and a drive motor 602 for driving the lifting lead screw 6 to rotate, with the top of the lifting lead screw 6 rotatably connected to a base 1.

[0059] In a specific implementation, the mounting platform 4 of this embodiment is provided with a translation slide rail 401, the slide table 5 is slidably disposed on the translation slide rail 401, and the translation drive unit includes a translation screw 402 that is rotatably connected to the mounting platform 4 at both ends and can be driven to rotate by an external drive unit, and a translation nut 403 that is screwed to the translation screw 402 and connected to the slide table 5.

[0060] Furthermore, in this embodiment, the lower end of the lifting screw 6 is rotatably connected to a fixed frame 601, and the fixed frame 601 is equipped with a drive motor 602 that drives the lifting screw 6 to rotate. A guide column 603 is connected between the fixed frame 601 and the base 1, and the guide column 603 is slidably mounted on the slide table 5 to restrict the rotation of the base 1 and the fixed frame 601 relative to the slide table 5.

[0061] By setting up a translation mechanism, the slide table 5 can be moved by the translation drive unit, providing precise guidance and power for the translation of the adhesive applicator along the Y-axis. At the same time, the lifting screw 6 and the screw nut 501 work together to drive the adhesive applicator to rise and fall, ensuring the accuracy and controllability of the lifting process.

[0062] Furthermore, by placing the lifting mechanism on the slide table 5 of the translation mechanism, the center of gravity of the adhesive application mechanism, the lifting mechanism, and the slide table 5 are all located on the same line in the Z-axis direction. Compared with placing the translation mechanism on the lifting end of the lifting mechanism, this can improve the stability of the adhesive application mechanism when it moves in the Y-axis direction.

[0063] It is worth noting that, regarding the adhesive application device for the battery cell 9 in this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still shown in the figure.

[0064] The adhesive applicator for the battery cell 9 in this embodiment includes an adhesive applicator mechanism and a moving mechanism. The adhesive applicator mechanism includes a base 1, a plurality of adhesive applicator components 2 slidably disposed on the base 1, and a locking mechanism disposed on each adhesive applicator component 2. The plurality of adhesive applicator components 2 are arranged along the X-axis direction, and each adhesive applicator component 2 can be driven to slide along the X-axis direction.

[0065] The base 1 has a guide rod 101 extending along the X-axis, and the adhesive application assembly 2 slides along the guide rod 101. A locking mechanism includes a locking member 3 on the adhesive application assembly 2, which can be operated to clamp the guide rod 101. The base 1 has a first slide rail 102 extending along the X-axis, and the adhesive application assembly 2 slides along the first slide rail 102. Furthermore, in this embodiment, a fixed adhesive application assembly 2a is fixedly connected to the base 1. The structure of the fixed adhesive application assembly 2a is the same as the other adhesive application mechanisms slidably mounted on the base 1. The guide rod 101 is fixedly connected to the fixed adhesive application assembly 2a, and the fixed connection base serves as the connection base between the guide rod 101 and the base 1.

[0066] Furthermore, the adhesive application assembly 2 includes a frame 201, a tape reel 202, a tape dispensing roller assembly, and an adhesive application plate 203 mounted on the frame 201. The tape dispensing roller assembly guides the tape in the tape reel 202 to the adhesive application plate 203, and includes multiple rollers 204, with the tape sequentially passing over the rollers 204 along a preset path. The frame 201 is slidably mounted on the first slide rail 102 and slidably passes through the guide rod 101. The adhesive application plate 203 is located on the side of the frame 201 near the battery cell 9 and extends towards the battery cell 9 along the Y-axis. The tape is then conveyed to the top of the adhesive application plate 203.

[0067] Additionally, the adhesive application assembly 2 includes a cutting unit 205. The cutting unit 205 includes a first drive unit 2051 mounted on the frame 201 and a cutter 2052 connected to the drive end of the first drive unit 2051. The end of the adhesive application plate 203 has a channel 2031 through which the cutter 2052 passes, allowing the cutter 2052 to be driven to extend from the channel 2031 and cut the adhesive tape. In this embodiment, the cutter 2052 and the channel 2031 extend along the Y-axis. The first drive unit 2051 in this embodiment is a telescopic cylinder well-known to those skilled in the art; this telescopic cylinder is mounted on the frame 201 and located on one side of the adhesive application plate 203.

[0068] Furthermore, the adhesive application assembly 2 includes a pressing unit 206. The pressing unit 206 includes a second drive unit 2061 mounted on the frame 201, and a pressing head connected to the drive end of the second drive unit 2061. The pressing head can be driven to press the adhesive tape tightly against the top of the adhesive application plate 203. The second drive unit 2061 is a telescopic cylinder well-known to those skilled in the art. The adhesive application assembly 2 also includes a de-adhesion unit 207. The de-adhesion unit 207 includes a cylinder 2071 and a slider 2072 slidably mounted on the frame 201 and connected to the piston rod of the cylinder 2071. The slider 2072 has at least one of a plurality of rollers 204, and the rollers 204, when driven to slide, can change the extension length of the adhesive tape in a preset path. The frame 201 has a second slide rail 2073, which guides the slider 2072 to slide, thereby improving the smoothness of the rollers 204's movement and preventing the adhesive tape from being torn.

[0069] Furthermore, the cell 9 adhesive applicator also includes a moving mechanism, with an adhesive applicator connected to its moving end. The adhesive applicator can be driven by the moving mechanism to move along at least one of the Y-axis and Z-axis directions, with the X-axis, Y-axis, and Z-axis directions being perpendicular to each other. The moving mechanism includes a translation mechanism and a lifting mechanism.

[0071] The adhesive applicator for the battery cell 9 in this embodiment adopts the above design. Through the cooperation of multiple adhesive applicator components 2 and locking mechanism, the multiple adhesive applicator components 2 can slide and lock their positions on the base 1. This not only allows multiple tapes to be applied to the battery cell 9 at the same time, but also allows the spacing between adjacent adhesive applicator components 2 to be changed, thereby adjusting the adhesive spacing on the battery cell 9. This improves the efficiency of applying adhesive to the battery cell 9 and can adapt to battery cells 9 of different sizes or adhesive application positions, thus enhancing versatility.

[0072] An embodiment of the second aspect of this application provides a battery production system, which, in terms of overall structure, combines... Figure 7 As shown, the battery production system includes a conveyor line 7 and a movable fixture 8 mounted on the conveyor line 7 for carrying battery cells 9. The conveyor line 7 has an adhesive application station, and the adhesive application station is equipped with adhesive application equipment for battery cells 9 as described above.

[0073] The battery production system of this embodiment, through the setting of the above-mentioned cell 9 adhesive application equipment, can simultaneously apply multiple adhesive tapes to the cell 9 and adjust the spacing of the adhesive tapes, thereby improving the working efficiency of cell 9 adhesive application. It eliminates the need to set up multiple adhesive application equipment, thereby reducing the equipment cost and maintenance cost of the battery production system and facilitating the miniaturization design of the battery production system.

[0074] Based on the above overall introduction, specifically, combined with Figure 8 As shown, the support platform 801 on the moving jig 8 of this embodiment is provided with a clearance groove 8011 on the side facing the adhesive applicator for the battery cell 9. By providing the clearance groove 8011, the adhesive applicator 2, that is, the adhesive applicator plate 203 in the adhesive applicator 2, can be cleared, so that the adhesive applicator plate 203 can extend under the battery cell 9 to apply adhesive to the bottom of the battery cell 9.

[0075] Meanwhile, the support platform 801 has an end plate 802 on the side facing the adhesive applicator for the battery cell 9, which abuts against the battery cell 9. The end plate 802 has a clearance notch 8021 for avoiding the adhesive applicator assembly 2. With the end plate 802, the end plate 802 can abut against the battery cell 9 and press the Mylar film on the battery cell 9 to prevent the Mylar film on the battery cell 9 from shifting during the adhesive applicator process.
