Description

Technical Field

[0001] This application belongs to the field of new energy battery processing equipment technology, and in particular relates to an adhesive application mechanism and adhesive application device. Background Technology

[0002] In the processing of new energy batteries (such as lithium batteries and zinc batteries), adhesive strips need to be applied to at least one side of the battery cell by an adhesive applicator to prevent the multi-layered battery cells from becoming loose after being stacked.

[0003] Existing adhesive application mechanisms include a drive assembly and an adhesive application head. The drive assembly drives the adhesive application head to move up, down, and laterally, while the adhesive application head provides the adhesive strip. Existing adhesive application mechanisms typically employ a C-type adhesive application method disclosed in CN207116599U. In this method, the drive assembly first drives the adhesive application head to adhere a portion of the adhesive strip to the first side of the battery cell. Then, the drive assembly drives the adhesive application head to move laterally, then move up and down, and finally move laterally again, so that the adhesive strip wraps around the side of the battery cell and adheres to the second side of the battery cell. This adhesive application method involves many steps and has low efficiency. Moreover, during the adhesive application process, the adhesive application head applies pressure to the battery cell to be adhesiveped. When the battery cell is relatively thin, the adhesive strip may not adhere well, thus affecting the adhesive application quality of the battery cell. Utility Model Content

[0004] The purpose of this application is to provide an adhesive application mechanism to solve the above-mentioned problems of existing adhesive application mechanisms. In addition, another purpose of this application is to provide an adhesive application device including the adhesive application mechanism.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] In a first aspect, this application proposes an adhesive application mechanism, which includes a first drive assembly, a movable base, and at least one set of adhesive application components, wherein:

[0007] At least one adhesive application assembly is installed on the movable base. The drive end of the first drive assembly is connected to the movable base. The first drive assembly is configured to drive the movable base to translate, thereby moving the adhesive application assembly between the adhesive dispensing station and the adhesive application station.

[0008] The adhesive application assembly includes a lifting drive, a lifting base, a first adsorption component, a second adsorption component, and a second drive assembly. The lifting drive is mounted on a movable base, and the drive end of the lifting drive is connected to the lifting base. The lifting drive is configured to drive the lifting base to lift.

[0009] The first adsorption element is installed on the lifting base, and the second adsorption element is arranged side by side with the first adsorption element. The second adsorption element is rotatably installed on the lifting base, and the first and second adsorption elements are configured to work together to adsorb the same adhesive strip.

[0010] The second drive assembly is mounted on the lifting base. The drive end of the second drive assembly is connected to the second adsorption component. The second drive assembly is configured to drive the second adsorption component to rotate by a preset angle.

[0011] The adhesive application mechanism proposed in this application, after the first drive component drives the adhesive application component to move to the adhesive dispensing station and adsorbs an adhesive strip, the first drive component then drives the adhesive application component and the adsorbed adhesive strip to move to the adhesive application station. When applying adhesive to multi-layered battery cells stacked at the adhesive application station, the lifting drive component drives the lifting seat to descend a preset height, first adsorbing part of the adhesive strip onto the first side of the battery cell, and then the second drive component drives the second adsorbent component to rotate a preset angle close to the first adsorbent component, moving the remaining adhesive strip adsorbed by the second adsorbent component to below the second side of the battery cell and adsorbing it onto the second side and side of the battery cell, thus realizing lateral adhesive application to the battery cell. Compared with the existing adhesive application method, it simplifies the adhesive application process and improves the adhesive application efficiency. Moreover, no pressure is applied to the battery cell in the thickness direction during the adhesive application process, avoiding deformation of the battery cell during adhesive application, thus making it suitable for lateral adhesive application to relatively thin battery cells. At the same time, when the second adsorbent component applies adhesive, the cooperation between the first and second adsorbent components can generate a certain clamping force on the battery cell, improving the adhesive application quality.

[0012] Optionally, the second drive assembly includes a rotary drive and a rotary frame, wherein:

[0013] The rotating frame is rotatably mounted on the lifting seat, and the second adsorption component is mounted on the rotating frame;

[0014] The fixed end of the rotary drive is mounted on the lifting seat, and the driving end of the rotary drive is connected to the rotating frame. The rotary drive is configured to drive the rotating frame to rotate, thereby causing the second adsorption component to rotate by a preset angle, so that the adsorption surface of the second adsorption component rotates to a position opposite to the adsorption surface of the first adsorption component.

[0015] By rotatably mounting the rotating frame on the lifting base and mounting the second adsorption component on the rotating frame, and connecting the driving end of the rotating drive component to the rotating frame, the rotating drive component drives the second adsorption component to rotate by a preset angle when driving the rotating frame to rotate. This provides a second drive component with a simple structure and stable and reliable operation.

[0016] Optionally, the first adsorption element is adjustablely mounted on the lifting base via a waist hole, or the adhesive application assembly may further include an adjustment component, the fixed end of which is mounted on the lifting base, the adjusting end of which abuts against the first adsorption element, and the adjustment component is configured to adjust the distance between the first adsorption element and the second adsorption element.

[0017] By adjusting the distance between the first and second adsorption components, the adhesive application mechanism can be adapted to apply adhesive to battery cells of different stacking thicknesses, thus improving the compatibility of the adhesive application mechanism.

[0018] Optionally, both the first and second adsorption components include a substrate. The adsorption surface of the substrate is evenly distributed with multiple adsorption holes. An air extraction channel is opened in the substrate and connected to the multiple adsorption holes. The air extraction channel is connected to an air extraction component through a pipe. The air extraction component draws air from the air extraction channel to form a negative pressure on the adsorption surface of the substrate for adsorbing the adhesive strip.

[0019] By setting multiple adsorption holes on the adsorption surface of the substrate and setting an air extraction channel connected to the multiple adsorption holes in the substrate, the air extraction component draws air from the air extraction channel, thereby forming a negative pressure on the adsorption strip, providing a first adsorption element and a second adsorption element with simple structure and stable and reliable adsorption.

[0020] Secondly, this application also proposes an adhesive applicator, which includes a frame and a feeding mechanism, a pulling mechanism, a cutting mechanism, and an adhesive applicator mounted on the frame, wherein:

[0021] The feeding mechanism is located on the first side of the glue-taking station and is configured to supply tape to the pulling mechanism.

[0022] The material pulling mechanism is located on the second side of the glue taking station, and the material pulling mechanism is configured to pull the tape on the material feeding mechanism to the glue taking station along the first horizontal direction.

[0023] The cutting mechanism is located below the glue dispensing station and is configured to work with the adhesive applicator to cut the tape at the glue dispensing station into strips of a predetermined length.

[0024] The adhesive applicator is located above the adhesive dispensing station. The adhesive applicator is configured to pick up an adhesive strip at the adhesive dispensing station and to apply the picked-up adhesive strip to the surface of the battery cell at the adhesive applicator station.

[0025] The adhesive applicator proposed in this application supplies adhesive tape to the pulling mechanism via a feeding mechanism. The pulling mechanism then guides the adhesive tape from the feeding mechanism to the adhesive dispensing station. A cutting mechanism, in conjunction with the adhesive applicator, cuts the adhesive tape at the dispensing station into strips of a predetermined length. The adhesive applicator then picks up one strip from the dispensing station and applies it to the surface of the battery cell, thus achieving automatic adhesive applicator application to the battery cell. Furthermore, the feeding mechanism, pulling mechanism, cutting mechanism, and adhesive applicator are roughly arranged in a cross shape, resulting in a reasonable overall layout and minimal space occupation. Additionally, the adhesive applicator offers advantages such as high adhesive applicator efficiency, good adhesive applicator quality, and suitability for lateral adhesive applicator application to relatively thin battery cells.

[0026] Optionally, the material pulling mechanism includes a first driving member, a transverse sliding seat, a second driving member, a first clamping member, and a second clamping member, wherein:

[0027] The fixed end of the first driving member is mounted on the frame, and the driving end of the first driving member is connected to the transverse slide seat. The first driving member is configured to drive the transverse slide seat to move closer to or away from the feeding mechanism in a first horizontal direction.

[0028] The fixed end of the second drive member is mounted on the transverse seat, and the drive end of the second drive member is connected to the first clamping member and the second clamping member. The second drive member is configured to drive the first clamping member and the second clamping member to move closer or further away from each other, so as to control the clamping or releasing of the ends of the tape by the first clamping member and the second clamping member.

[0029] The first driving component drives the transverse seat to move closer to the feeding mechanism, thereby moving the first clamping component and the second clamping component to the position of clamping the tape. The second driving component drives the first clamping component and the second clamping component to move closer to each other, thereby clamping the end of the tape. Then, the first driving component drives the transverse seat to move away from the feeding mechanism, thereby pulling the tape on the feeding mechanism to the adhesive dispensing station. This provides a high-efficiency, stable and reliable material pulling mechanism.

[0030] Optionally, a first clamping roller is installed at the clamping end of the first clamping member, and a second clamping roller is installed at the clamping end of the second clamping member. The first clamping roller is located above the second clamping roller. The bottom surface of the tape is the adhesive surface. The roller surface of the second clamping roller is coated with a non-stick coating, and / or the roller surface of the second clamping roller is provided with a plurality of grooves.

[0031] The first and second clamping rollers achieve the clamping or releasing of the tape, ensuring line contact between the first and second clamping components and the tape. This reduces the contact area between the first and second clamping rollers and the tape while maintaining stable and reliable clamping, thus mitigating any potential adverse effects on the tape during clamping. Furthermore, coating the surface of the second clamping roller with a non-adhesive coating prevents adhesive from adhering to the tape's bonding surface, thus maintaining the tape's adhesion. Finally, creating several grooves on the surface of the second clamping roller further reduces the contact area, further minimizing any potential adverse effects on the tape during clamping.

[0032] Optionally, the cutting mechanism includes a third drive unit, a lifting unit, a support platform, and a cutting blade, wherein:

[0033] The fixed end of the third drive component is mounted on the frame, and the lifting component is mounted on the frame in a liftable manner. The drive end of the third drive component is connected to the lifting component, and the third drive component is configured to drive the lifting component to lift.

[0034] The support platform can be installed on the lifting component by means of a flexible connection component. The support platform is configured to support the tape at the adhesive dispensing station. The bottom surface of the tape is the adhesive surface. The support surface of the support platform is coated with a non-stick coating, and / or the support platform is provided with a protrusion. The top surface of the protrusion is the support surface of the support platform.

[0035] The cutting blade is vertically mounted on the lifting component and located on the side of the support platform. The cutting blade's cutting edge is lower than the support surface of the support platform when the elastic connecting component is not retracted.

[0036] By mounting the support platform and the cutting blade on the lifting component, when the third drive component drives the lifting component to rise, it causes the support platform and the cutting blade to rise synchronously. Because the cutting blade's blade is lower than the support surface of the support platform when the elastic connecting component is not retracted, the support platform first supports the tape at the adhesive dispensing station from below and, together with the first and second adsorption components of the adhesive applicator, positions the tape. Then, the third drive component drives the lifting component to continue rising. After the elastic connecting component retracts, the cutting blade's blade extends out of the support surface of the support platform to cut the tape. This provides a cutting mechanism with high cutting accuracy and stable and reliable operation. Moreover, the support surface of the support platform is coated with a non-stick coating, which can prevent the adhesive on the tape's adhesive surface from adhering to the support platform when the support surface of the support platform contacts the adhesive surface of the tape, thus affecting the tape's adhesive performance. A protrusion is provided on the support platform, and the top surface of the protrusion serves as the support surface of the support platform, which can reduce the contact area between the support surface of the support platform and the tape, reducing the potential adverse effects of the support platform on the tape during tape cutting.

[0037] Optionally, a glue dispensing station is set on each side of the frame. Each glue dispensing station is equipped with a feeding mechanism, a pulling mechanism and a cutting mechanism around its perimeter. The glue application mechanism has two sets of glue application components, which are installed alternately on the moving base. Each set of glue application components corresponds to one glue dispensing station.

[0038] By setting up a glue-taking station on each side of the frame, and equipping each glue-taking station with a feeding mechanism, a pulling mechanism and a cutting mechanism around it, and each glue-taking station corresponding to a set of glue-applying components, the glue can be applied to two stacked groups of multiple battery cells at the same time, which improves the glue-applying efficiency; at the same time, the two sets of glue-applying components share a first drive component, which simplifies the overall structure.

[0039] Optionally, the feeding mechanism includes an unwinding assembly, a tension control assembly, and a tension stop assembly arranged sequentially along the travel direction of the conveyor belt, wherein:

[0040] The unwinding assembly includes a carrier roller and a fourth drive member. The carrier roller is configured to receive and fix the roll, and the drive end of the fourth drive member is connected to the carrier roller and configured to release the tape from the roll.

[0041] The tension control assembly includes a tension roller and an elastic element. The elastic element is connected to the tension roller, and a portion of the tape abuts against the tension roller. The elastic element is configured to adjust the tension of the tape in real time via the tension roller.

[0042] The tension barrier assembly is configured to compress the tape before the cutting mechanism cuts the tape.

[0043] The automatic release of the tape roll is achieved through the cooperation of the fourth drive component and the bearing roller; the real-time adjustment of the tape tension is achieved through the cooperation of the tension roller and the elastic component; and the tape is pressed before cutting by setting a tension isolation component, thereby isolating the tape tension at the tape dispensing station from that of the tape in the feeding mechanism, and further improving the cutting accuracy.

[0059] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] In the processing of new energy batteries, to prevent the multi-layered cells from loosening after stacking, an adhesive strip needs to be applied to at least one side of the cell using an adhesive applicator. Existing adhesive applicators typically use a C-type adhesive applicator, which includes a drive assembly and an adhesive applicator head. The drive assembly first drives the adhesive applicator head to adhere a portion of the adhesive strip to the first side of the cell. The drive assembly then drives the adhesive applicator head to move laterally, then rise and fall, and finally move laterally again, so that the adhesive strip wraps around the side of the cell and adheres to the second side of the cell. This adhesive applicator method has many steps and low adhesive applicator efficiency. Moreover, during the adhesive applicator process, the adhesive applicator head applies pressure to the cell to be applicated. When the cell is relatively thin, the adhesive strip may not adhere well, thus affecting the quality of the adhesive applicator.

[0061] Therefore, in the first aspect, this application proposes an adhesive application mechanism 10, please refer to... Figures 1 to 5As shown, the adhesive applicator 10 proposed in this embodiment includes a first driving component 11, a movable base 12, and at least one set of adhesive applicator components 13. At least one set of adhesive applicator components 13 is mounted on the movable base 12. The driving end of the first driving component 11 is connected to the movable base 12. The first driving component 11 is at least configured to drive the movable base 12 to translate, thereby moving the adhesive applicator components 13 between the adhesive dispensing station and the adhesive applicator station. The adhesive applicator components 13 include a lifting drive component 130, a lifting base 131, a first suction component 132, a second suction component 133, and a second driving component 134. The lifting drive component 130 is mounted on the movable base 12. The drive end of 30 is connected to the lifting seat 131, and the lifting drive component 130 is configured to drive the lifting seat 131 to rise and fall; the first adsorption component 132 is installed on the lifting seat 131, and the second adsorption component 133 is arranged side by side with the first adsorption component 132. The second adsorption component 133 is rotatably installed on the lifting seat 131, and the first adsorption component 132 and the second adsorption component 133 are configured to cooperate to adsorb the same adhesive strip; the second drive assembly 134 is installed on the lifting seat 131, and the drive end of the second drive assembly 134 is connected to the second adsorption component 133. The second drive assembly 134 is configured to drive the second adsorption component 133 to rotate a preset angle.

[0062] Specifically, the first drive assembly 11 includes a mounting plate 110, a transverse drive module 111, a lifting cylinder 112, and a lifting plate 113. The movable seat 12 can move along the first horizontal direction ( Figure 1 The transverse drive module 111 is mounted on the mounting plate 110 in the X direction. The fixed end of the transverse drive module 111 is mounted on the mounting plate 110. The movable end of the transverse drive module is connected to the moving seat 12. The transverse drive module 111 is configured to drive the moving seat 12 to translate in the first horizontal direction. The fixed end of the lifting cylinder 112 is mounted on the moving seat 12. The driving end of the lifting cylinder 112 is connected to the lifting plate 113. The lifting plate 113 is mounted on the moving seat 12 in a height-reducible manner. The lifting cylinder 112 is configured to drive the lifting plate 113 to lift. At least one set of adhesive application assembly 13 is mounted on the lifting plate 113.

[0063] Specifically, a sliding guide pair consisting of a linear guide rail and a slider is provided between the movable seat 12 and the mounting plate 110 to improve the smoothness of the movable seat 12's translation along the first horizontal direction; a sliding guide pair consisting of a linear guide rail and a slider is provided between the lifting plate 113 and the movable seat 12 to improve the smoothness of the lifting plate 113's lifting.

[0064] The general working principle of the adhesive application mechanism proposed in this application is as follows:

[0065] In the glue-taking process, the first drive assembly 11 first drives the adhesive application assembly 13 to move directly above the glue-taking station. Then, the lifting cylinder 112 drives the lifting plate 113 to descend and cooperates with the lifting drive component 130 to drive the lifting seat 131 to descend to a preset height. The first adsorption component 132 and the second adsorption component 133 work together to adsorb the same adhesive strip located at the glue-taking station.

[0066] In the adhesive application process, the first drive assembly 11 first drives the adhesive application assembly 13 and the adsorbed adhesive strip to move directly above the adhesive application station. Then, the lifting cylinder 112 drives the lifting plate 113 to descend and cooperates with the lifting drive component 130 to drive the lifting seat 131 to descend to the adhesive application position, so that part of the adhesive strip adsorbed by the first adsorbent 132 is pasted on the first side of the battery cell. Finally, the second drive assembly 134 drives the second adsorbent 133 to rotate close to the first adsorbent 132 at a preset angle, moving the remaining adhesive strip adsorbed by the second adsorbent 133 to the bottom of the second side of the battery cell and pasting it on the second side of the battery cell. Here, the first side is the upper surface of the battery cell and the second side is the lower surface of the battery cell. During the rotation process, the adhesive strip will also be pasted on the side of the battery cell.

[0067] As can be seen, the adhesive applicator 10 proposed in this application can achieve automatic lateral adhesive application to the battery cell. Compared with the existing adhesive application method, the adhesive application action of the adhesive applicator 10 in this application only requires lowering and then rotating, which simplifies the adhesive application process and improves the adhesive application efficiency. Moreover, it can be applied to relatively thin battery cells laterally. At the same time, when the second adsorption member 133 applies adhesive, the first adsorption member 132 and the second adsorption member 133 cooperate to generate a certain clamping force on the battery cell, which improves the adhesive application quality.

[0068] In one embodiment, the second drive assembly 134 includes a rotary drive 1340 and a rotary frame 1341. The rotary frame 1341 is rotatably mounted on the lifting seat 131, and the second adsorption member 133 is mounted on the rotary frame 1341. The fixed end of the rotary drive 1340 is mounted on the lifting seat 131, and the drive end of the rotary drive 1340 is connected to the rotary frame 1341. The rotary drive 1340 is configured to drive the rotary frame 1341 to rotate, thereby causing the second adsorption member 133 to rotate by a preset angle, so that the adsorption surface of the second adsorption member 133 rotates to a position opposite to the adsorption surface of the first adsorption member 132.

[0069] Specifically, the rotary drive 1340 is either an electric motor or a rotary cylinder.

[0070] As can be seen, by rotatably mounting the rotating frame 1341 on the lifting seat 131 and mounting the second adsorption member 133 on the rotating frame 1341, and connecting the driving end of the rotating drive member 1340 to the rotating frame 1341, the rotating drive member 1340 drives the second adsorption member 133 to rotate by a preset angle when driving the rotating frame 1341 to rotate, thus providing a second drive component 134 with a simple structure and stable and reliable operation.

[0071] In one embodiment, the first adsorption member 132 is adjustablely mounted on the lifting seat 131 through the waist hole, or the adhesive application assembly 13 may also include an adjustment assembly (not shown in the figure), the fixed end of the adjustment assembly is mounted on the lifting seat 131, the adjustment end of the adjustment assembly abuts against the first adsorption member 132, and the adjustment assembly is configured to adjust the distance between the first adsorption member 132 and the second adsorption member 133.

[0072] Specifically, the first adsorption element 132 can be adjusted and fixedly mounted on the lifting base 131, either close to or far from the second adsorption element 133. The driving component of the adjustment assembly can be any one of an adjusting screw, an adjusting motor, or an adjusting cylinder.

[0073] If an adjusting screw is used, the adjusting screw is rotatably mounted on the lifting seat 131, and the tail end of the adjusting screw abuts against the first adsorption member 132. When adjusting the distance, the first adsorption member 132 is loosened relative to the lifting seat 131, and the adjusting screw is rotated. The adjusting screw pushes the first adsorption member 132 closer to the second adsorption member 133 to adjust the distance between the first adsorption member 132 and the second adsorption member 133.

[0074] If an adjustable cylinder is used, the fixed end of the adjustable cylinder is installed on the lifting seat 131, and the driving end of the adjustable cylinder is connected to the first adsorption element 132. When adjusting the distance, the first adsorption element 132 is released relative to the lifting seat 131, and the adjustable cylinder is activated to drive the first adsorption element 132 to move closer to or further away from the second adsorption element 133, so as to adjust the distance between the first adsorption element 132 and the second adsorption element 133.

[0075] If an adjustable pitch motor is used, the fixed end of the adjustable pitch motor is installed on the lifting base 131, the driving end of the adjustable pitch motor is connected to the first end of the transmission assembly, and the second end of the transmission assembly is connected to the first adsorption member 132. The transmission assembly is used to convert the rotational motion of the adjustable pitch motor into the linear motion of the first adsorption member 132. The transmission assembly can be a ball screw type or a synchronous belt type linear transmission pair. When adjusting the pitch, the first adsorption member 132 is released relative to the lifting base 131, and the adjustable pitch motor is started to drive the first adsorption member 132 to move closer to or further away from the second adsorption member 133 through the transmission assembly, so as to adjust the distance between the first adsorption member 132 and the second adsorption member 133.

[0076] It can be seen that by adjusting the distance between the first adsorption member 132 and the second adsorption member 133, the adhesive application mechanism 10 can apply adhesive to multiple battery cells with different stacking thicknesses, thereby improving the compatibility of the adhesive application mechanism 10.

[0077] In one embodiment, both the first adsorption member 132 and the second adsorption member 133 include a substrate 1320. A plurality of adsorption holes 1321 are evenly distributed on the adsorption surface of the substrate 1320. An air extraction channel is provided in the substrate 1320 and communicates with the plurality of adsorption holes 1321. The air extraction channel is connected to an air extraction component through a pipe. The air extraction component draws air from the air extraction channel to form a negative pressure on the adsorption surface of the substrate 1320 for adsorbing the adhesive strip.

[0078] Specifically, the air extraction component is an air pump.

[0079] As can be seen, by providing multiple adsorption holes 1321 on the adsorption surface of the substrate 1320 and providing an air extraction channel connected to the multiple adsorption holes 1321 in the substrate 1320, the air extraction component draws air from the air extraction channel, thereby forming a negative pressure on the adsorption strip, providing a first adsorption element 132 and a second adsorption element 133 with a simple structure and stable and reliable adsorption.

[0080] The adhesive application mechanism 10 proposed in this application embodiment has the following advantages:

[0081] 1) The process of applying adhesive has been simplified, and the efficiency of applying adhesive has been improved;

[0082] 2) It is suitable for lateral bonding of relatively thin battery cells;

[0083] 3) When applying adhesive, the first adsorption component 132 and the second adsorption component 133 work together to generate a certain clamping force on the battery cell, which improves the quality of adhesive application.

[0084] 4) The spacing between the first adsorption component 132 and the second adsorption component 133 is adjustable, which can meet the requirements of applying adhesive to battery cells with different stacking thicknesses, and has good compatibility.

[0085] Secondly, this application also proposes an adhesive applicator, please refer to [link to relevant documentation]. Figure 1 As shown, the adhesive applicator proposed in this embodiment includes a frame 20 and a feeding mechanism 30, a pulling mechanism 40, a cutting mechanism 50, and an adhesive applicator 10 disposed on the frame 20. The feeding mechanism 30 is disposed on the first side of the adhesive dispensing station and is configured to supply adhesive tape 60 to the pulling mechanism 40; the pulling mechanism 40 is disposed on the second side of the adhesive dispensing station and is configured to move along a first horizontal direction ( Figure 1The tape 60 on the feeding mechanism 30 is pulled to the glue-taking station in the X direction. The cutting mechanism 50 is located below the glue-taking station and is configured to cooperate with the glue-applying mechanism 10 to cut the tape 60 at the glue-taking station into glue strips of a predetermined length. The glue-applying mechanism 10 is located above the glue-taking station and is configured to pick up a glue strip at the glue-taking station. The glue-applying mechanism 10 is also configured to apply the picked-up glue strip to the surface of the battery cell at the glue-applying station.

[0086] Specifically, the first side and the second side are the opposite sides of the glue-taking station in the first horizontal direction.

[0087] As can be seen, the adhesive applicator proposed in this application supplies adhesive tape 60 to the pulling mechanism 40 through the feeding mechanism 30. The pulling mechanism 40 pulls the adhesive tape 60 on the feeding mechanism 30 to the adhesive taking station. The cutting mechanism 50, in conjunction with the adhesive applicator 10, cuts the adhesive tape 60 at the adhesive taking station into strips of a predetermined length. The adhesive applicator 10 picks up one strip of adhesive from the adhesive taking station and applies the picked-up strip to the surface of the battery cell, thus realizing automatic adhesive applicator application to the battery cell. Moreover, the feeding mechanism 30, the pulling mechanism 40, the cutting mechanism 50, and the adhesive applicator 60 are roughly arranged in a cross shape, with a reasonable overall layout and small space occupation. At the same time, the adhesive applicator 10 has the advantages of high adhesive applicator efficiency, good adhesive applicator quality, and suitability for lateral adhesive applicator application to relatively thin battery cells.

[0088] Please see Figure 1 and Figure 6 As shown, in one embodiment, the feeding mechanism 40 includes a first driving member 41, a transverse seat 42, a second driving member 43, a first clamping member 44, and a second clamping member 45. The fixed end of the first driving member 41 is mounted on the frame 20, and the driving end of the first driving member 41 is connected to the transverse seat 42. The first driving member 41 is configured to drive the transverse seat 42 to move closer to or away from the feeding mechanism 30 in a first horizontal direction. The fixed end of the second driving member 43 is mounted on the transverse seat 42, and the driving end of the second driving member 43 is connected to the first clamping member 44 and the second clamping member 45. The second driving member 43 is configured to drive the first clamping member 44 and the second clamping member 45 to move closer to or away from each other, so as to control the first clamping member 44 and the second clamping member 45 to clamp or release the end of the tape 60.

[0089] Specifically, both the first driving component 41 and the second driving component 43 are cylinders, and a sliding guide pair consisting of a linear guide rail and a slider is provided between the transverse shift seat 42 and the frame 20 to improve the stability of the transverse shift seat 42.

[0090] As can be seen, the material pulling mechanism 40 drives the transverse seat 42 to move closer to the feeding mechanism 30 via the first driving member 41, so as to move the first clamping member 44 and the second clamping member 45 to the position of clamping the tape 60. The second driving member 43 drives the first clamping member 44 and the second clamping member 45 to move closer to each other, so as to clamp the end of the tape 60 via the first clamping member 44 and the second clamping member 45. Then, the first driving member 41 drives the transverse seat 42 to move away from the feeding mechanism 30, so as to pull the tape 60 on the feeding mechanism 30 to the adhesive picking station. This provides a material pulling mechanism 40 with high working efficiency and stable and reliable material pulling.

[0091] In one embodiment, a first clamping roller 46 is installed at the clamping end of the first clamping member 44, and a second clamping roller 47 is installed at the clamping end of the second clamping member 45. The first clamping roller 46 is located above the second clamping roller 47, the bottom surface of the tape 60 is the adhesive surface, and the roller surface of the second clamping roller 47 is coated with a non-stick coating.

[0092] As can be seen, the clamping or releasing of the tape 60 is achieved by the first clamping roller 46 and the second clamping roller 47, so that the first clamping member 44 and the second clamping member 45 are in line contact with the tape 60. Under the premise of ensuring stable and reliable clamping, the contact area between the first clamping roller 46 and the second clamping roller 47 and the tape 60 is reduced, thereby reducing the adverse effects that the first clamping roller 46 and the second clamping roller 47 may have on the tape 60 when clamping it. By coating the roller surface of the second clamping roller 47 with a non-adhesive coating, it is possible to avoid the adhesive on the bonding surface of the tape 60 adhering to the second clamping roller 47 when the second clamping roller 47 is in contact with the bonding surface of the tape 60, thus affecting the bonding performance of the tape 60.

[0093] In one embodiment, the surface of the second clamping roller 47 is provided with a plurality of grooves.

[0094] It can be seen that by opening several grooves on the roller surface of the second clamping roller 47, the contact area between the second clamping roller 47 and the tape 60 can be further reduced, thereby further reducing the adverse effects that the second clamping roller 47 may have on the tape 60 when clamping it.

[0095] Please see Figure 1 and Figure 7As shown, in one embodiment, the cutting mechanism 50 includes a third driving member 51, a lifting member 52, a support platform 53, and a cutting blade 54. The fixed end of the third driving member 51 is mounted on the frame 20. The lifting member 52 is mounted on the frame 20 in a lifting manner. The driving end of the third driving member 51 is connected to the lifting member 52. The third driving member 51 is configured to drive the lifting member 52 to lift. The support platform 53 is mounted on the lifting member 52 in a floating manner via an elastic connecting component 55. The support platform 53 is configured to support the adhesive tape 60 at the adhesive dispensing station. The bottom surface of the adhesive tape 60 is the adhesive surface. The support surface of the support platform 53 is coated with a non-adhesive coating, and / or the support platform 53 is provided with a protrusion. The top surface of the protrusion is the support surface of the support platform 53. The cutting blade 54 is vertically mounted on the lifting member 52 and located on the side of the support platform 53. The blade of the cutting blade 54 is lower than the support surface of the support platform 53 when the elastic connecting component 55 is not retracted.

[0096] Specifically, the elastic connection component 55 includes a spring, the upper end of which abuts against the bottom surface of the support platform 53, and the lower end of which is mounted on the lifting component 52.

[0097] Specifically, the third driving component 51 is a cylinder, and a sliding guide pair consisting of a linear guide rail and a slider is provided between the lifting component 52 and the frame 20 to improve the smoothness of the lifting component 52.

[0098] Specifically, a clearance notch 56 is provided on the side of the support platform 53 near the material pulling mechanism 40. The clearance notch 56 is used to allow the first clamping member 44 and the second clamping member 45 to pass when the material pulling mechanism 40 clamps the tape 60, so as to facilitate clamping the end of the tape 60.

[0099] Specifically, the protrusion can be either a rib or a truncated cone.

[0100] As can be seen, by mounting the support platform 53 and the cutting blade 54 on the lifting component 52, when the third drive component 51 drives the lifting component 52 to rise, it causes the support platform 53 and the cutting blade 54 to rise synchronously. Because the blade of the cutting blade 54 is lower than the support surface of the support platform 53 when the elastic connecting component 55 is not retracted, the support platform 53 will first support the tape at the adhesive dispensing station from below the tape 60 and cooperate with the first suction component 132 and the second suction component 133 of the adhesive applicator 10 to position the tape 60. Then, the third drive component 51 drives the lifting component 52 to continue to rise. After the elastic connecting component 55 retracts, the blade of the cutting blade 54 extends out of the support platform. The support surface of the support platform 53 cuts the tape 60, providing a cutting mechanism 50 with high cutting accuracy and stable and reliable operation. Furthermore, the support surface of the support platform 53 is coated with a non-stick coating, which prevents adhesive from adhering to the adhesive surface of the tape 60 when the support surface of the support platform 53 contacts the adhesive surface of the tape 60, thus avoiding any impact on the adhesive performance of the tape 60. A protrusion is provided on the support platform 53, with the top surface of the protrusion serving as the support surface of the support platform 53. This reduces the contact area between the support surface of the support platform 53 and the tape 60, minimizing any adverse effects that the support platform 53 may have on the tape 60 during tape cutting.

[0101] In one implementation, a glue-taking station is provided on each side of the frame 20. Each glue-taking station is equipped with a feeding mechanism 30, a pulling mechanism 40 and a cutting mechanism 50. The glue-applying mechanism 10 has two sets of glue-applying components 13, which are installed alternately on the movable seat 12. Each set of glue-applying components 13 corresponds to one glue-taking station.

[0102] As can be seen, by setting a glue-taking station on each side of the frame 20, and equipping each glue-taking station with a feeding mechanism 30, a pulling mechanism 40 and a cutting mechanism 50 around its perimeter, and with each glue-taking station corresponding to a set of glue-applying components 13, the glue can be applied to two stacked groups of multiple battery cells simultaneously, thus improving the glue-applying efficiency; at the same time, the two sets of glue-applying components 13 share a first driving component 11, which simplifies the overall structure.

[0103] Please see Figure 1 and Figure 8As shown, in one embodiment, the feeding mechanism 30 includes an unwinding assembly 31, a tension control assembly 32, and a tension interruption assembly 33 arranged sequentially along the traveling direction of the tape 60. The unwinding assembly 31 includes a carrier roller 310 and a fourth drive member (not shown in the figure). The carrier roller 310 is configured to receive and fix the tape roll. The drive end of the fourth drive member is connected to the carrier roller 310 and configured to release the tape 60 from the tape roll. The tension control assembly 32 includes a tension roller 320 and an elastic member 321. The elastic member 321 is connected to the tension roller 320, and a portion of the tape 60 abuts against the tension roller 320. The elastic member 321 is configured to adjust the tension of the tape 60 in real time via the tension roller 320. The tension interruption assembly 33 is configured to press the tape 60 before the cutting mechanism 50 cuts the tape 60.

[0104] Specifically, the carrier roller 310 is rotatably mounted on the frame 20, the fourth drive is a motor, the drive end of the fourth drive is connected to the carrier roller 310, and the fourth drive is configured to drive the carrier roller 310 to rotate in order to release the tape 60 of the material roll.

[0105] Specifically, the tension control assembly 32 also includes a movable seat 322 and two limit seats 323. The two limit seats 323 are installed at intervals along a first horizontal direction on the frame 20. The movable seat 322 is movably installed on the frame 20 along the first horizontal direction and is located between the two limit seats 323. The tension roller 320 is installed on the movable seat 322. The first end of the elastic element 321 abuts against one of the limit seats 323, and the second end of the elastic element 321 abuts against the movable seat 322. The elastic element 321 is a spring.

[0106] Specifically, the tension isolation assembly 33 includes a fifth driving member 330, an upper pressing member 331, and a lower pressing member 332. The upper pressing member 331 is fixedly installed on the frame 20, and the lower pressing member 332 is movably positioned directly below the upper pressing member. The fixed end of the fifth driving member 330 is installed on the frame 20, and the driving end of the fifth driving member 330 is connected to the lower pressing member 332. The fifth driving member 330 is configured to drive the lower pressing member 332 to rise and fall. The fifth driving member 330 drives the lower pressing member 332 to rise and press and fix the upper pressing member 331 and the lower pressing member 332 through the cooperation of the upper pressing member 331. The fifth driving member 330 is a cylinder.

[0107] As can be seen, the automatic release of the tape 60 roll is achieved through the cooperation of the fourth driving component and the bearing roller 310; the real-time adjustment of the tension of the tape 60 is achieved through the cooperation of the tension roller 320 and the elastic component 321; and the tape 60 is pressed before cutting by setting the tension isolation component 33, thereby isolating the tension of the tape 60 at the glue taking station from the tape 60 of the feeding mechanism 30, and further improving the cutting accuracy.

[0108] In one embodiment, the feeding mechanism 30 further includes a detection component 34 and a plurality of guide rollers 35. The detection component 34 is disposed on the movement path of the conveyor belt 60 and is configured to detect whether the conveyor belt 60 released by the feeding mechanism 30 has deviated. At least one or more of the guide rollers 35, the carrier rollers 310 and the tension rollers 320 are movably mounted on the frame 20 in a second horizontal direction. After the detection component 34 detects that the conveyor belt 60 has deviated, it controls the guide rollers 35, the carrier rollers 310 or the tension rollers 320 to move in the second horizontal direction to adjust the deviated conveyor belt 60.

[0112] 3) The material pulling mechanism 40 has high working efficiency and stable and reliable operation; moreover, by clamping the end of the tape 60 with two clamping rollers, the contact area between the two clamping rollers and the tape 60 is reduced, thereby reducing the adverse effects that the two clamping rollers may have on the tape 60 when clamping the tape.

[0113] 4) Before cutting the tape 60, the cutting mechanism 50 works with the adhesive applicator 10 to position the tape 60, preventing the tape 60 from shifting during cutting and improving the cutting accuracy of the tape.

[0114] 5) The adhesive is applied to multiple cells stacked on two sets at the same time, which is highly efficient; at the same time, the two adhesive application assemblies 13 share a first drive assembly 11, which makes the overall structure simple.
