Description

Technical Field

[0001] This application relates to the technical field of new energy vehicle battery production, and in particular to a commercial vehicle large-area adhesive application equipment. Background Technology

[0002] In the assembly process of commercial vehicle battery packs, the batteries need to be bonded and fixed together using double-sided adhesive to ensure the overall structural stability and safety of the battery pack.

[0003] like Figure 1 To accommodate the transportation, storage, and subsequent bonding of double-sided adhesive, the related technology incorporates release paper on both the top and bottom sides of the adhesive layer. To facilitate the removal of the release paper, tear-off ears are provided on the outer side of the release paper. Furthermore, the tear-off ears on the top and bottom sides of the release paper are staggered to avoid interference during the tearing process.

[0004] Currently, the double-sided adhesive bonding operation on the battery surface is mainly completed using automated adhesive application equipment. Specifically, through the coordinated operation of various actuators inside the equipment, the double-sided adhesive is first gripped and positioned, then the bottom release paper is peeled off, and one side of the adhesive layer of the double-sided adhesive is bonded to the target battery surface. Finally, the remaining top release paper of the adhesive layer is peeled off, achieving precise bonding between the double-sided adhesive and the battery.

[0005] Regarding the aforementioned technologies, due to the different operating conditions and functional requirements of batteries in different locations within the battery pack, batteries need to be bonded with either thermally conductive double-sided adhesive (hereinafter referred to as Type A double-sided adhesive) or cushioning double-sided adhesive (hereinafter referred to as Type B double-sided adhesive). Current adhesive application equipment only has the capability to apply a single type of double-sided adhesive, typically requiring multiple machines to work together to complete the application of various types of double-sided adhesive. This results in high space requirements for actual adhesive application operations, making it difficult to adapt to space-constrained environments and severely restricting battery adhesive application. Summary of the Invention

[0006] To address the issue that existing adhesive application equipment can only perform adhesive application of a single type of double-sided tape and cannot be compatible with both Type A and Type B double-sided tape, this application provides a large-area adhesive application equipment for commercial vehicles.

[0007] This application provides a commercial vehicle large-area adhesive application equipment, which adopts the following technical solution:

[0008] A commercial vehicle large-area adhesive application device includes a material storage mechanism, a conveying mechanism, a first gripping mechanism, a first adhesive-tearing mechanism, a second gripping mechanism, and a second adhesive-tearing mechanism.

[0009] The storage mechanism includes a storage trolley, which is equipped with a storage assembly. The storage assembly includes two storage sections, which are used to stack and store Type A double-sided tape and Type B double-sided tape, respectively.

[0010] The conveying mechanism includes two parallel conveyor belts, which are used to convey Type A double-sided adhesive and Type B double-sided adhesive, respectively.

[0011] The first gripping mechanism is used to grip Type A double-sided tape and Type B double-sided tape located in the two storage sections respectively, and transfer them to the first peeling mechanism to cooperate with the first peeling mechanism to peel off the bottom release paper of both Type A double-sided tape and Type B double-sided tape. It is also used to transfer the Type A double-sided tape and Type B double-sided tape with the bottom release paper removed and place them respectively on the two conveyor belts of the conveying mechanism.

[0012] Both the second gripping mechanism and the second adhesive-tearing mechanism are connected to the battery pack conveyor line used in conjunction with the commercial vehicle large-area adhesive-applying equipment;

[0013] The second gripping mechanism is used to selectively grip the Type A or Type B double-sided adhesive located on the conveying mechanism and bond it to the target battery being conveyed by the battery pack conveying line;

[0014] The second adhesive-removing mechanism is used to remove the top release paper of the Type A or Type B double-sided adhesive that is bonded to the target battery.

[0015] By adopting the above technical solution, during battery adhesive application, the first gripping mechanism picks up Type A and Type B double-sided adhesives located at the material storage component and transfers them to the first peeling mechanism. The first peeling mechanism simultaneously peels off the bottom release paper of both types of double-sided adhesives. Subsequently, the first gripping mechanism transfers the Type A and Type B double-sided adhesives, with their bottom release paper removed, to two separate conveyor belts on the conveying mechanism for independent transport. When the battery pack conveyor line transports the target battery to the corresponding adhesive application station, the second gripping mechanism selectively picks up the corresponding type of double-sided adhesive from the conveyor belt and precisely adheres it to the surface of the target battery. Finally, the second peeling mechanism peels off the top release paper of the adhered double-sided adhesive, completing the entire adhesive application process. Compared to traditional adhesive application equipment, this method achieves compatibility between two types of double-sided adhesive application operations with a single machine, eliminating the need for multiple independent machines and significantly reducing the space requirements of the adhesive application equipment in the production area. It is effectively suitable for battery adhesive application operations in space-constrained locations.

[0016] Preferably, the storage unit includes a storage bracket, a storage plate, and a lifting drive. The storage bracket is provided with a storage station, and the storage plate is supported on the storage station of the storage bracket. The storage plate is used to place double-sided tape, and the lifting drive is used to drive the storage plate to rise and fall.

[0017] By adopting the above technical solution, after the first gripping mechanism grips the double-sided tape located on the top of the storage plate, the storage plate can be driven to rise and fall vertically by the lifting drive component, so that the top of the stacked double-sided tape is always within the gripping range of the first gripping mechanism, realizing automatic replenishment of double-sided tape without frequent adjustment of the gripping position of the first gripping mechanism, realizing automated replenishment in the feeding process, which is conducive to improving work efficiency.

[0018] Preferably, the storage bracket is vertically supported with a plurality of limiting stops corresponding to the storage plate. The limiting stops are all inserted through the corresponding storage plate, and the plurality of limiting stops are distributed around the storage plate to circumferentially limit the double-sided adhesive.

[0019] By adopting the above technical solution, on the one hand, by using several limiting stops to form a circumferential limiting boundary for the double-sided tape stacking area, it is beneficial to limit the horizontal displacement of the double-sided tape during stacking and lifting, and avoid the situation where the double-sided tape is offset or tilted, affecting the gripping of the first gripping mechanism. On the other hand, the storage plate can be guided and limited by several limiting stops, which is conducive to the storage plate being lifted and lowered more effectively in the vertical direction.

[0020] Preferably, an ionizing air bar is supported on the top of the storage rack, and the air outlet of the ionizing air bar is positioned facing the top of the storage station.

[0021] When the first gripping mechanism grips the target double-sided tape located on the top of the storage plate, the ion air bar blows positive and negative charged airflow toward the target double-sided tape to remove dust and impurities from the surface of the double-sided tape and eliminate static electricity between adjacent double-sided tapes.

[0022] By adopting the above technical solution, when the first gripping mechanism performs the top double-sided tape gripping action, the ion air bar blows positive and negative charged airflows toward the target double-sided tape and adjacent double-sided tape areas. On the one hand, the airflow can effectively blow away dust and impurities on the surface of the target double-sided tape and in the stacking gaps, making it easier for the first gripping mechanism to grip the target double-sided tape more firmly. On the other hand, it helps to quickly neutralize the static electricity generated between the double-sided tapes due to stacking friction, eliminating the problem of multiple double-sided tapes sticking together due to static adsorption.

[0023] Preferably, the synchronous belt structure of the conveyor belt has a plurality of strip-shaped protrusions uniformly protruding on its outer periphery, the strip-shaped protrusions being used for bonding the adhesive layer of the double-sided adhesive; the strip-shaped protrusions are all coated with a non-stick coating.

[0024] By adopting the above technical solution, the contact area between the adhesive layer and the synchronous belt structure is reduced, avoiding large-area adhesion caused by the adhesive layer directly bonding to the synchronous belt surface. At the same time, it can effectively reduce the contact and adsorption of impurities such as chips and dust on the synchronous belt structure surface with the adhesive layer, effectively reducing the impact of impurities on the adhesive layer's bonding performance.

[0025] Preferably, the outer periphery of the synchronous belt structure of the conveyor belt is also uniformly provided with a plurality of limiting strips, and adjacent limiting strips form a limiting groove structure for double-sided adhesive to be embedded.

[0026] By adopting the above technical solution, the limiting groove structure formed by adjacent limiting bars is used to limit the double-sided tape placed on the conveyor belt, effectively constraining the horizontal displacement of the double-sided tape during the operation of the conveyor belt, avoiding the double-sided tape from shifting or tilting due to the acceleration, deceleration or vibration of the conveyor belt, ensuring that the double-sided tape always maintains the preset conveying posture, which in turn facilitates the subsequent second gripping mechanism to more accurately grip the target double-sided tape located on the conveyor belt.

[0027] Preferably, each of the limiting bars has a correction notch in the middle;

[0028] The end of the conveyor belt is supported by a straightening assembly; the straightening assembly includes a straightening rod and a straightening drive, the straightening rod is disposed opposite to the straightening notch of the limiting stop bar, and the straightening drive is used to drive the straightening rod to move in a direction closer to or away from the straightening notch;

[0029] When the conveyor belt delivers the double-sided adhesive to its end, the straightening drive causes the straightening rod to be inserted into the straightening notch corresponding to the limiting strip, so as to straighten and limit the double-sided adhesive located in the limiting groove.

[0030] By adopting the above technical solution, when the conveyor belt transports the double-sided tape to the end, the straightening drive unit drives the straightening rod to move toward the straightening notch of the limit bar and embed it. The straightening rod is used to straighten and limit the double-sided tape, so as to correct the slight deviation of the double-sided tape during the transport process. This helps to keep the double-sided tape in the preset reference position, which makes it easier for the subsequent second gripping mechanism to grip the target double-sided tape on the conveyor belt more accurately.

[0031] Preferably, the first adhesive-tearing mechanism includes a first adhesive-tearing component and a first collection hopper;

[0032] The first adhesive-tearing assembly includes a first adhesive-tearing section and a lateral drive component;

[0033] The first adhesive-tearing section includes an adhesive-tearing support rod and two adhesive-tearing supports; the adhesive-tearing support rod is provided with a plurality of first clamping ears for clamping the release paper tearing ears; the adhesive-tearing support rod is rotatably connected between the two adhesive-tearing supports, and the adhesive-tearing supports are provided with swinging drive components for driving the adhesive-tearing support rod to swing around its own rotation axis.

[0034] The lateral drive component is driven to the two adhesive tearing supports, and is used to drive the two adhesive tearing supports to move the adhesive tearing support rod in the horizontal direction.

[0035] The first collecting hopper is located below the moving path of the adhesive-tearing support rod.

[0036] By adopting the above technical solution, after the first gripping mechanism transfers the Type A and Type B double-sided adhesives to the first tearing mechanism, the first clamping lug on the tearing support rod clamps the tearing lug of the release paper located on the bottom side of the double-sided adhesive. Then, the swing drive drives the tearing support rod to swing the first clamping lug downward. The vertical downward pulling force generated by the swing creates an initial peeling gap between the release paper and the bottom surface of the adhesive layer. After the initial peeling is completed, the transverse drive drives the two tearing supports to move the tearing support rod horizontally. The remaining unpeeled release paper is completely torn off by the continuous horizontal pulling force. The torn release paper falls into the first collection hopper below under the action of gravity for centralized recycling, which is conducive to the automated tearing and recycling of release paper.

[0037] Preferably, the second adhesive-tearing mechanism includes a second adhesive-tearing component and a second collection hopper;

[0038] The second adhesive-tearing assembly includes an adhesive-tearing robot and a second clamping ear, the second clamping ear being connected to the drive end of the adhesive-tearing robot; the second clamping ear is used to hold the tear tab of the release paper.

[0039] By adopting the above technical solution, after the double-sided adhesive is bonded to the target battery, the adhesive-tearing robot, in conjunction with the second clamping ear of the second adhesive-tearing component, holds the corresponding double-sided adhesive tearing ear and pulls the release paper along a preset trajectory so that the release paper is smoothly peeled off along the top surface of the adhesive layer.

[0040] Preferably, it also includes a testing mechanism; the testing mechanism includes a control system and an adhesive application testing component;

[0041] The adhesive application detection component includes an adhesive application camera;

[0042] The adhesive-applying camera is positioned facing the adhesive-applying station of the battery pack conveyor line;

[0043] Both the adhesive-coated camera and the second gripping mechanism are connected to the control system.

[0044] The adhesive-applying camera is used to acquire battery position data at the adhesive-applying station on the battery pack conveyor line and feed it back to the control system. The control system is used to control the second gripping mechanism to apply the corresponding double-sided adhesive to the target battery based on the battery position data.

[0045] By adopting the above technical solution, the battery position data at the adhesive application station of the battery pack conveyor line is collected in real time by the adhesive application camera and fed back to the control system. This allows the control system to calculate the actual adhesive application coordinates based on the data, which helps the subsequent control system to more accurately control the second gripping mechanism to bond the double-sided adhesive layer to the target battery.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] 1. Through the coordinated operation of the material storage mechanism, conveying mechanism, first gripping mechanism, first adhesive-removing mechanism, second gripping mechanism, and second adhesive-removing mechanism, the simultaneous supply, application, and removal of release paper for Type A and Type B double-sided adhesives are achieved. This allows a single machine to complete the application of multiple types of double-sided adhesives without the need for additional application equipment, which significantly reduces the space requirements of the equipment in the production area.

[0048] 2. By having the first clamping ear of the adhesive-tearing support rod clamp the corresponding release paper tearing ear, the swinging drive unit drives the first clamping ear to swing downward, which helps to quickly break the initial adhesion between the release paper and the adhesive layer, and avoids the adhesive layer from being deformed or displaced when the release paper is moved horizontally in the subsequent process.

[0049] 3. By setting several strip-shaped protrusions on the synchronous belt structure, on the one hand, it helps to reduce the contact area between the adhesive layer and the synchronous belt structure, avoiding the situation where the adhesive layer is directly bonded to the surface of the synchronous belt structure, which would lead to difficulties in subsequent detachment; on the other hand, it reduces the contact and adsorption of impurities such as chips and dust on the surface of the synchronous belt structure with the adhesive layer, reducing the impact of impurities on the adhesive layer's bonding performance.

[0066] The following is in conjunction with the appendix Figure 2-14 This application will be described in further detail.

[0067] This application discloses a commercial vehicle large-area adhesive application device, referring to... Figure 2The system includes a frame 1, on which are mounted a storage mechanism 2, a conveying mechanism 3, a first gripping mechanism 4, a first adhesive-removing mechanism 5, a second gripping mechanism 6, a second adhesive-removing mechanism 7, and a detection mechanism. The storage mechanism 2 stores Type A and Type B double-sided adhesives. The conveying mechanism 3 conveys Type A and Type B double-sided adhesives. The first gripping mechanism 4 transfers Type A and Type B double-sided adhesives from the storage mechanism 2 to the first adhesive-removing mechanism 5, allowing the first adhesive-removing mechanism 5 to remove the bottom release paper from the Type A and Type B double-sided adhesives. The first gripping mechanism 4 also places the Type A and Type B double-sided adhesives with the bottom release paper removed onto the conveying mechanism 3. The second gripping mechanism 6 and the second adhesive-removing mechanism 7 connect to a battery pack conveyor line used with the adhesive application equipment. The second gripping mechanism 6 selectively adheres Type A or Type B double-sided adhesives from the conveying mechanism 3 to the target battery conveyed by the battery pack conveyor line. The second adhesive-removing mechanism 7 removes the top release paper from the double-sided adhesive adhered to the target battery.

[0068] Reference Figure 2 and Figure 3 The storage mechanism 2 includes a storage trolley 20, which is equipped with storage components. In this embodiment, there are two storage components, one for standby and one for use during actual operation. The storage components include two storage sections 21. The two storage sections 21 are used to store Type A and Type B double-sided adhesive, respectively.

[0069] Reference Figure 3 and Figure 4 The storage section 21 includes a storage bracket 210, a storage plate 211, and a lifting drive 212. The storage bracket 210 is provided with a storage station. The storage plate 211 is supported on the storage station of the storage bracket 210 and is used to place stacked double-sided tape. The lifting drive 212 is used to drive the storage plate 211 to rise and fall. Specifically, the lifting drive 212 includes an electric screw vertically arranged on one side of the storage bracket 210. The slide of the electric screw is connected and fixed to the corresponding storage plate 211, realizing the driving connection between the lifting drive 212 and the storage plate 211. The electric screw drives the storage plate 211 to move the stack of double-sided tape vertically up and down.

[0070] After the first gripping mechanism 4 grips a single sheet of double-sided tape located on top of the storage plate 211, the lifting drive 212 drives the storage plate 211 to rise vertically, so that the top of the stacked double-sided tape is always within the gripping range of the first gripping mechanism 4, realizing automatic replenishment of double-sided tape. There is no need to frequently adjust the gripping position of the first gripping mechanism 4, which helps to ensure the working efficiency of the first gripping mechanism 4.

[0071] Reference Figure 3 and Figure 4The storage bracket 210 is vertically supported by several limiting stops 213 corresponding to the storage plate 211. The bottom end of each limiting stop 213 is fixed to the storage bracket 210, and each limiting stop 213 passes through the corresponding storage plate 211. The limiting stops 213 are distributed around the outer perimeter of the storage plate 211. The limiting stops 213 are formed with receiving grooves corresponding to the tear-off ears of the double-sided adhesive release paper. The receiving grooves are used for embedding the tear-off ears so that they can be neatly stored.

[0072] By using several limiting stops 213, a circumferential limiting boundary is formed for the double-sided tape stacking area, which helps to limit the horizontal displacement of the double-sided tape due to external loads during stacking and lifting, and avoids the double-sided tape from affecting the gripping process of the first gripping mechanism 4 due to offset or tilting; at the same time, the limiting stops 213 can be used to guide and limit the storage plate 211, which is conducive to the storage plate 211 being lifted and lowered more effectively in the vertical direction.

[0073] Reference Figure 3 and Figure 4 An ionizing air bar 214 is mounted on the top of the storage rack 210, with its air outlet facing the top of the storage station. When the first gripping mechanism 4 grips the target double-sided tape located on top of the storage plate 211, the ionizing air bar 214 blows positive and negative charged airflows toward the target double-sided tape. On the one hand, the airflow removes dust and impurities from the surface of the target double-sided tape and the gaps between stacks, which helps the first gripping mechanism 4 grip the target double-sided tape more firmly; on the other hand, it can quickly neutralize the static electricity generated between adjacent double-sided tapes due to stacking friction, eliminating the problem of multiple double-sided tapes sticking together due to electrostatic adsorption, thus helping the first gripping mechanism 4 to grip a single double-sided tape stably.

[0074] Reference Figure 3 and Figure 4 Each storage trolley 20 is equipped with a sliding linear module 22 corresponding to the storage bracket 210. The sliding linear module 22 is driven to the corresponding storage bracket 210 and is used to drive the storage bracket 210 to move into or out of the storage trolley 20, which facilitates the replenishment of double-sided tape.

[0075] Reference Figure 5 and Figure 6 The conveying mechanism 3 includes two parallel conveyor belts 31, which are arranged side by side and are used to convey type A double-sided adhesive and type B double-sided adhesive respectively.

[0076] Reference Figure 5 and Figure 7The synchronous belt structure 310 of the conveyor belt 31 has several uniformly protruding strips 311 on its outer periphery. These strips 311 are made of silicone and coated with a non-stick coating made of silicone oil. The cross-section of each strip 311 is trapezoidal, narrower at the top and wider at the bottom. Both ends of each strip 311 extend to both sides of the synchronous belt structure 310. Gaps are left between adjacent strips 311. When the first gripping mechanism 4 places the double-sided adhesive (with the bottom release paper removed) onto the corresponding synchronous belt structure 310 of the conveyor belt 31, the strips 311 reduce the contact area between the double-sided adhesive layer and the synchronous belt structure 310. This prevents the adhesive layer from directly adhering to the surface of the synchronous belt structure 310, thus avoiding large-area adhesion and ensuring the second gripping mechanism 6 can remove the double-sided adhesive from the conveyor belt 31. Furthermore, this reduces direct contact between the adhesive layer and dust and impurities on the surface of the synchronous belt structure 310, effectively minimizing the impact of impurities on the adhesive's bonding performance.

[0077] Reference Figure 5 and Figure 6 The synchronous belt structure 310 of the conveyor belt 31 is also uniformly provided with several limiting strips 312 on its outer periphery. Adjacent limiting strips 312 form a limiting groove structure for embedding double-sided adhesive. After the double-sided adhesive is placed into the limiting groove, the limiting groove can effectively constrain the horizontal displacement of the double-sided adhesive during the operation of the conveyor belt 31, avoiding the double-sided adhesive from shifting or tilting due to the acceleration, deceleration or vibration of the conveyor belt 31, ensuring that the double-sided adhesive always maintains the preset conveying posture, which makes it easier for the subsequent second gripping mechanism 6 to more accurately grip the target double-sided adhesive on the conveyor belt 31.

[0078] Reference Figure 5 and Figure 6 Each of the limiting stops 312 has a correction notch 3121 in the middle. A correction assembly is supported at the end of the conveyor belt 31, comprising a correction rod 33 and a correction drive 34. The correction rod 33 is positioned opposite the correction notch 3121 of the limiting stops 312 at the end of the conveyor belt 31. The correction drive 34 is driven by the correction rod 33, driving the correction rod 33 to move towards or away from the correction notch 3121 of the limiting stops 312 at the end of the conveyor belt 31. Specifically, the correction drive 34 is a cylinder.

[0079] When the conveyor belt 31 conveys the double-sided tape to its end, the straightening drive 34 drives the straightening rod 33 to insert into the straightening notch 3121 of the corresponding limit stop 312. The straightening rod 33 is used to straighten and limit the double-sided tape to correct the slight deviation of the double-sided tape during the conveying process, so that the double-sided tape maintains the preset reference position, which is convenient for the subsequent second gripping mechanism 6 to grip accurately.

[0080] Reference Figure 5 and Figure 8Each conveyor belt 31 has a cleaning unit 32 installed at its bottom. The cleaning unit 32 includes a cleaning box 321, with both ends of the cleaning box 321 connected to the two sides of the conveyor belt 31 frame via baffles. A cleaning brush 322 is installed inside the cleaning box 321, with the bristles of the brush abutting against the bottom of the synchronous belt structure 310. Gaps are left between the cleaning brush 322 and the inner cavity of the cleaning box 321 on opposite sides. The cleaning brush 322 removes dust and impurities adhering to the synchronous belt structure 310, and the brushed-off dust and impurities fall into the cleaning box 321 through the gaps between the cleaning brush 322 and the inner cavity of the cleaning box 321. A dust collection trough 323 is inserted into the end of the cleaning box 321, located below the cleaning brush 322, to collect the brushed-off dust and impurities. A cleaning air knife is installed on the side of the cleaning box 321 facing the starting end of the conveyor belt 31, and the cleaning air knife is positioned towards the synchronous belt structure 310.

[0081] Reference Figure 2 and Figure 9 The first gripping mechanism 4 includes a first robotic arm and a first gripping assembly 41. The first robotic arm adopts an existing parallel robot, and the first gripping assembly 41 is connected to the drive end of the first robotic arm. The first gripping assembly 41 includes a first gripping bracket 411. The bottom of the first gripping bracket 411 is provided with two first gripping parts. The first gripping part includes a first gripping seat 412 supported at the bottom of the first gripping bracket 411. The first gripping seat 412 is vertically mounted with a plurality of first gripping suction cups 413 for holding double-sided adhesive release paper.

[0082] When the first gripping mechanism 4 grips the double-sided tape, the first robotic arm drives the two first gripping parts of the first gripping assembly 41 to move above the target double-sided tape, and the first gripping suction cup 413 of the first gripping part holds the release paper on the top side of the target double-sided tape, thus completing the gripping of the target double-sided tape.

[0083] Reference Figure 2 and Figure 9 The first gripping bracket 411 is equipped with an adjustment drive component 410 corresponding to a first gripping seat 412. The adjustment drive component 410 is drivenly connected to the corresponding first gripping seat 412 and is used to drive the corresponding first gripping seat 412 to move relative to the other first gripping seat 412. Specifically, the adjustment drive component 410 is a cylinder. When the size of the double-sided tape changes later, the relative distance between the two first gripping parts can be adjusted so that the two first gripping parts can better grip type A double-sided tape and type B double-sided tape respectively.

[0084] Reference Figure 2 and Figure 10 The first adhesive-tearing mechanism 5 includes a first adhesive-tearing assembly and a first collection hopper 54. The first adhesive-tearing assembly includes a first adhesive-tearing section and a lateral drive member 53.

[0085] Reference Figure 10 and Figure 11 The first adhesive-tearing section includes an adhesive-tearing support rod 51 and two adhesive-tearing supports 52. The two ends of the adhesive-tearing support rod 51 are rotatably connected to the two adhesive-tearing supports 52 through bearing structures. The adhesive-tearing support rod 51 is provided with a plurality of first clamping ears 511 for clamping the release paper tear ears at the two first gripping parts of the first gripping bracket 411. The first clamping ears 511 are used to clamp the release paper tear ears.

[0086] Reference Figure 10 and Figure 11 The first clamping member 511 includes a first fixed clamping block 5111, a first movable clamping block 5112, and a first clamping cylinder 5113. The first fixed clamping block 5111 is fixed on the release paper support rod 51. The first movable clamping block 5112 is supported on the top of the first fixed clamping block 5111. The first clamping cylinder 5113 is fixed to the outside of the first fixed clamping block 5111. The piston rod at the top of the first clamping cylinder 5113 is connected to the first movable clamping block 5112 to drive the first movable clamping block 5112 to move relative to the first fixed clamping block 5111, thereby achieving the clamping of the release paper tear-off ear.

[0087] Reference Figure 10 and Figure 11 The adhesive-tearing support 52 is provided with a swing drive 521 for driving the adhesive-tearing support rod 51 to rotate around its own rotation axis. The swing drive 521 includes a rotary cylinder mounted on the adhesive-tearing support 52. The rotating end of the rotary cylinder is connected to the end of the adhesive-tearing support rod 51. The rotary cylinder drives the adhesive-tearing support rod 51 to swing the first clamping ear 511.

[0088] The lateral movement drive unit 53 includes two lateral movement linear modules. The two lateral movement linear modules are supported on the equipment frame 1 by brackets. The two lateral movement linear modules are respectively driven connected to two adhesive tearing supports 52, which are used to drive the adhesive tearing support rod 51 to move in the horizontal direction.

[0089] Reference Figure 10 and Figure 11 The first collecting hopper 54 is located below the moving path of the adhesive-tearing support rod 51.

[0090] After the first gripping mechanism 4, in conjunction with the first gripping component 41, transfers Type A and Type B double-sided adhesives to the first peeling mechanism 5, the first clamping ear 511 on the peeling support rod 51 clamps the peeling ear on the release paper located on the bottom side of the corresponding double-sided adhesive. Then, the swing drive 521 drives the peeling support rod 51 to swing the first clamping ear 511 downward. The vertical downward pulling force generated by the swing creates an initial peeling gap between the release paper and the bottom surface of the adhesive layer. After the initial peeling is completed, the lateral drive 53 drives the two peeling supports 52 to move the peeling support rod 51 horizontally. The remaining unpeeled release paper is completely peeled off by the continuous horizontal pulling force. After the peeling is completed, the first clamping ear 511 releases its clamp, and the peeled release paper falls into the first collection hopper 54 below under the action of gravity for centralized recycling, realizing the automated peeling and recycling of the bottom release paper of the double-sided adhesive.

[0091] Reference Figure 2 and Figure 12 The second gripping mechanism 6 includes a second robotic arm and a second gripping assembly 61. The second robotic arm is an existing parallel robot, mounted vertically downwards on the top of the equipment frame 1. The second gripping assembly 61 is connected to the drive end of the second robotic arm. The second gripping assembly 61 includes a second gripping bracket 611. A connecting seat 612 is supported on one side of the second gripping bracket 611, and a second gripping seat 613 is supported on the other side of the connecting seat 612. Several second gripping suction cups 6131 are installed on the side of the second gripping seat 613 away from the connecting seat 612. The second gripping suction cups 6131 are used to hold double-sided adhesive release paper. The connecting seat 612 is provided with a translation drive 614 corresponding to the second gripping seat 613 for driving the second gripping seat 613 to move closer to or away from the connecting seat 612. The second gripping bracket 611 is provided with a rotation drive 615 corresponding to the connecting seat 612 for driving the connecting seat 612 to rotate the second gripping seat 613. Specifically, the translation drive 614 is a cylinder, and the rotation drive 615 is a geared motor.

[0092] When applying the adhesive, the second robotic arm of the second gripping mechanism 6, together with the second gripping suction cup 6131 of the second gripping component 61, grips the type A or type B double-sided adhesive on the corresponding conveyor belt 31 and attaches it to the side of the target battery, thus completing the bonding of the corresponding type of double-sided adhesive.

[0093] Reference Figure 13 and Figure 14The second adhesive-tearing mechanism 7 includes a second adhesive-tearing assembly and a second collection hopper 8. The second adhesive-tearing assembly includes an adhesive-tearing robot 71 and a second clamping ear. The second clamping ear is connected to the drive end of the adhesive-tearing robot 71 via a bracket and is used to clamp the tear tabs of the release paper. The second clamping ear includes a pneumatic gripper 72, and each of the two gripping blocks of the pneumatic gripper 72 is connected to a clamping ear block 721. The two clamping ear blocks 721 have mutually cooperating serrated surfaces on opposite sides to increase the contact area with the tear tabs.

[0094] After the double-sided adhesive is bonded to the target battery, the peeling robot 71, in conjunction with the second clamping lug, clamps the tearing lug on the remaining release paper of the double-sided adhesive and pulls the release paper along a preset trajectory to make the release paper be peeled off smoothly along the adhesive layer surface. Then, the peeling robot 71, in conjunction with the second clamping lug, moves the release paper above the second collection hopper 8, and the second clamping lug releases the clamp on the release paper tearing lug so that the release paper falls into the second collection hopper 8.

[0095] The testing mechanism includes a control system, a peel-off detection component, and an adhesive application detection component. The control system can use an existing PLC controller.

[0096] Reference Figure 2 and Figure 10 The adhesive tear detection component is located between the conveying mechanism 3 and the first adhesive tearing mechanism 5. The component includes two adhesive tearing cameras, which are vertically mounted on the equipment frame 1. The cameras are connected to the control system. The two cameras are used to acquire images of the bottom sides of both type A and type B double-sided adhesives gripped by the first gripping mechanism 4 and feed them back to the control system.

[0097] After the first peeling mechanism 5, in conjunction with the first gripping mechanism 4, completes the removal of the release paper from the bottom sides of both Type A and Type B double-sided adhesive tapes, the first gripping mechanism 4 moves the Type A and Type B double-sided adhesive tapes to the conveying mechanism 3. Then, it moves them to above two peeling cameras, where the cameras acquire images of the bottom sides of the tapes and feeds them back to the control system. This allows the control system to determine the removal status of the release paper from the bottom sides of both tapes.

[0098] Reference Figure 2 and Figure 12The adhesive application detection component includes an adhesive application camera. The adhesive application camera is positioned facing the adhesive application station on the battery pack conveyor line. Each drive component of the adhesive application camera and the second gripping mechanism 6 is connected to the control system. The adhesive application camera acquires battery position data and a target battery type image at the adhesive application station on the battery pack conveyor line and feeds this data back to the control system. The control system accurately calculates the actual adhesive application coordinates based on the battery position data and, based on the battery type image, controls the second gripping mechanism 6 to accurately adhere the corresponding double-sided adhesive to the target battery, thus improving the accuracy of the adhesive application.

[0099] The implementation principle of this application embodiment is as follows: During the adhesive application operation, the first gripping mechanism 4 grips the Type A and Type B double-sided adhesives located at the material storage component and transfers them to the first adhesive-tearing mechanism 5. The first gripping mechanism 4, in conjunction with the first adhesive-tearing mechanism 5, removes the bottom release paper from both Type A and Type B double-sided adhesives. Then, the first gripping mechanism 4 transfers the Type A and Type B double-sided adhesives with the bottom release paper removed to two conveyor belts 31, which transport the corresponding double-sided adhesives to the end. When the battery conveyor line used in conjunction with the adhesive application equipment transports the target battery to the adhesive application station, the second gripping mechanism 6 grips the corresponding type of double-sided adhesive on the conveyor belt 31 according to the target battery type and adheres it to the surface of the target battery. Finally, the second adhesive-tearing mechanism 7 removes the top release paper from the adhered double-sided adhesives to complete the adhesive application operation.

[0100] The adhesive application equipment of this application is compatible with the application of Type A and Type B double-sided tapes, eliminating the need for additional adhesive application equipment and effectively reducing the space requirements of the adhesive application equipment in the production site.

[0101] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
