Description

Technical Field

[0001] This invention relates to the field of automatic battery adhesive application technology, specifically to an automatic small round adhesive application device and method based on batteries. Background Technology

[0002] Bluetooth headsets contain batteries, and the positive terminal of the battery needs to be covered with high-temperature resistant tape. The battery casing has positioning lines on its side, and the tape must maintain a specific angle with these lines. The tape serves to provide insulation and reduce noise generated by the battery within the headset. Currently, the industry primarily uses manual methods to apply tape to the positive terminal of cylindrical batteries. First, a ring-shaped piece of tape is punched out using a mold. Then, a person uses a knife to remove the ring-shaped tape from the release paper and manually applies it to the positive terminal. This manual application method is inefficient, and during the process, factors such as operating techniques and fatigue can easily lead to misalignment or loose adhesion of the tape, resulting in inconsistent product quality. Consequently, after tape application, manual measurement and inspection of the battery's angle and coaxiality are required, which is not only labor-intensive and time-consuming but also difficult to guarantee in terms of accuracy, leading to poor product consistency, low overall production efficiency, and a high dependence on manual labor.

[0003] Therefore, a battery-based automatic small round adhesive applicator and method are proposed to solve the problems mentioned above. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic small round adhesive applicator and method based on batteries. A servo motor drives a rotating disk to rotate intermittently, causing batteries to flow sequentially between multiple stop positions, including a vision inspection position and an adhesive application position. A feeding module uses a lead screw module and cylinders to transfer batteries from the material box to the battery slot on the rotating disk. A discharging module transfers qualified batteries to the discharging box, and a defective product recycling module transfers defective products to the waste box. This replaces manual feeding, discharging, and sorting. Furthermore, based on the continuous cyclic operation design of S1-S6 in the automatic small round adhesive applicator method, the intermittent nature of manual operation is avoided, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a mounting plate, wherein the mounting plate is provided with a feeding module, an angle adjustment module, an adhesive tape feeding module, an adhesive tape cutting module, an adhesive tape transfer assembly, a feeding module, a primary vision inspection module, a secondary vision inspection module, and a coaxiality vision inspection module, wherein the primary vision inspection module is used to detect the angle of the battery, and the angle adjustment module is used to lift and rotate the battery;

[0007] The adhesive tape feeding module includes a vertical plate, a cutting surface steering guide wheel, an upper adhesive tape clamping unit, and a lower adhesive tape clamping unit.

[0010] Preferably, the adhesive tape feeding module further includes an unwinding roller, a winding roller, a cutting surface, multiple adhesive tape pulling guide rollers, and a winding buffer guide roller;

[0011] The unwinding roller is installed above one side of the vertical plate, and the winding roller is installed below the vertical plate on the same side as the unwinding roller. The cutting surface is fixedly installed on the side of the vertical plate away from the unwinding roller, and the cutting surface is used to support the adhesive tape to be cut.

[0012] Multiple adhesive-stretching guide wheels are installed in the middle of the side of the upright plate, the winding buffer guide wheel is disposed between the winding wheel and the cutting surface, the winding buffer guide wheel is slidably connected to the upright plate, and the cutting surface steering guide wheel is installed on the side of the upright plate near the cutting surface.

[0013] Preferably, the tape cutting module is a laser cutting module, which includes an adjustment bracket and a laser cutting head. The adjustment bracket is mounted on the mounting plate, and the laser cutting head is mounted on the adjustment bracket and located directly above the tape cutting surface. The adjustment bracket is used to adjust the height of the laser cutting head relative to the tape cutting surface.

[0014] Preferably, the adhesive tape transfer assembly further includes a cylinder and a vacuum nozzle. The lead screw module is mounted on the mounting plate via a bracket. The cylinder is vertically mounted on the moving end of the lead screw module, and the vacuum nozzle is mounted on the piston rod end of the cylinder.

[0015] Preferably, the upper clamping unit of the adhesive tape is disposed above the cutting surface, and the lower clamping unit of the adhesive tape is disposed below the cutting surface. The upper clamping unit of the adhesive tape includes a pressing cylinder and a pressing block, and the lower clamping unit of the adhesive tape includes a clamping cylinder and a clamping block.

[0016] Preferably, the L-shaped guide groove includes a horizontal section and a vertical section. The horizontal section of the L-shaped guide groove is parallel to the moving direction of the lead screw module. One end of the spring is fixed to the end of the rubber-cutting surface steering guide wheel that passes through the L-shaped guide groove. The other end of the spring is fixed to the guide plate. The fixing point of the spring and the guide plate is located on one side of the vertical section of the L-shaped guide groove.

[0017] Preferably, the angle adjustment module includes a lifting cylinder, a stepper motor, and a suction nozzle. The angle adjustment module is located directly below the primary vision inspection module. The lifting cylinder is vertically arranged, the stepper motor is installed at the end of the lifting cylinder, and the suction nozzle is installed on the telescopic shaft of the lifting cylinder.

[0018] Preferably, a secondary lifting cylinder is provided directly below the secondary visual inspection module. The secondary lifting cylinder is used to lift the battery. The secondary visual inspection module is used to detect the relative angle between the pasted battery and the adhesive tape. The coaxiality visual inspection module is used to detect the coaxiality between the pasted battery and the adhesive tape. The mounting plate is also provided with a defective product recycling module for recycling batteries that fail the angle detection or coaxiality detection.

[0019] The rotating disk has multiple battery slots evenly distributed along its edge. Each battery slot is used to accommodate a cylindrical battery. The rotating disk rotates intermittently under the drive of a servo motor. The rotating disk has multiple stop positions, namely, loading position, primary visual inspection position, adhesive application position, secondary visual inspection position, coaxiality inspection position, unloading position, and defective product recycling position.

[0020] A battery-based automatic method for applying small round adhesive strips includes the following steps:

[0021] S1: Loading operation: Place the material box containing cylindrical batteries into the loading module. The loading module is equipped with a No. 1 transfer component. By moving the No. 1 transfer component horizontally and lifting it vertically, the batteries in the material box are transferred to the battery slot of the material position on the rotating disk.

[0022] S2: First visual inspection and angle adjustment: The servo motor drives the rotating disk to rotate, transferring the battery in the battery slot to the first visual inspection position and stopping. The lifting cylinder of the angle adjustment module rises to lift the battery. The first visual inspection module captures an image of the battery and calculates the angle deviation, outputting an electrical signal to the stepper motor. The stepper motor drives the battery to rotate to a suitable angle. The lifting cylinder descends to put the battery back into the battery slot.

[0023] S3: Adhesive tape feeding and cutting: The unwinding wheel of the adhesive tape feeding module unwinds the tape, and the tape is laid on the cutting surface after being guided by the tape pulling guide wheel, the winding buffer guide wheel, and the cutting surface turning guide wheel. The tape is clamped by the tape upper clamping unit and the tape lower clamping unit. The laser cutting head of the tape cutting module cuts the tape according to a preset program.

[0024] S4: Adhesive application and inspection operation: The rotating disk transfers the battery after angle adjustment to the adhesive application position and stops. The adhesive tape transfer component transfers the cut ring-shaped adhesive tape to the positive electrode surface of the battery. Then the rotating disk continues to drive the battery to rotate. The secondary vision inspection module and the coaxiality vision inspection module detect whether the battery adhesive tape is qualified.

[0025] S5: Feeding and Defective Product Recycling: The rotating disk transfers the battery to the feeding position or the defective product recycling position. If it is a qualified product, the third transfer component of the feeding module transfers the battery to the feeding box. If it is a defective product, the fourth transfer component of the defective product recycling module transfers the battery to the waste box.

[0026] S6: Repeat steps S1-S5 to achieve continuous adhesive application.

[0027] Preferably, step S4 includes the following steps:

[0028] S41: The servo motor drives the rotating disk to transfer the angle-adjusted battery to the adhesive application position and stop. The lead screw module of the adhesive transfer assembly drives the cylinder and vacuum nozzle to move above the cutting surface. The cylinder descends, and the vacuum nozzle picks up the annular adhesive tape. At this time, the clamping unit above the adhesive tape is released. Then, the lead screw module drives the adhesive tape to move directly above the battery. The cylinder descends to stick the adhesive tape to the positive electrode surface of the battery. Then, the clamping unit above the adhesive tape clamps it, and the clamping unit below the adhesive tape releases it. Subsequently, the adhesive transfer assembly resets.

[0029] During the tape transfer process, the moving end of the tape transfer assembly drives the guide plate to move. The guide plate and the inclined slide groove drive the cutting surface steering guide wheel to move downwards in a direction away from the cutting surface. During each tape application operation, the cutting surface steering guide wheel moves an equal distance along the inclined slide groove, thereby quantitatively stretching the tape. During the tape transfer assembly reset process, the winding buffer guide wheel moves downwards, pulling the waste tape and release paper toward the winding wheel, which then tightens the tape.

[0030] S42: Secondary visual inspection: The rotating disk transfers the glued battery to the secondary visual inspection position and stops. The secondary lifting cylinder below the secondary visual inspection module rises and lifts the battery. The secondary visual inspection module detects the angle between the adhesive tape and the battery positioning line. Unqualified batteries are marked as defective products.

[0031] S43: Coaxiality Detection: The rotating disk transfers the battery to the coaxiality detection position and stops. The coaxiality visual detection module takes a picture of the battery, compares the position of the tape and the outer edge of the battery, and detects the coaxiality. Unqualified batteries are marked as defective products.

[0032] Compared with the prior art, the present invention provides a battery-based automatic small round adhesive applicator and method, which has the following beneficial effects:

[0033] 1. The servo motor drives the rotating disk to rotate intermittently, causing the batteries to flow sequentially between multiple stop positions such as the first visual inspection position and the adhesive application position. The feeding module transfers the batteries in the material box to the battery slot of the rotating disk through the lead screw module and cylinder. The unloading module transfers qualified products to the unloading material box, and the defective product recycling module transfers defective products to the waste box, replacing manual feeding, unloading and sorting. At the same time, based on the continuous cycle operation design of SS in the automatic small round adhesive application method, the intermittent nature of manual operation is avoided, greatly reducing the dependence on manual labor and improving the overall adhesive application efficiency.

[0034] 2. The adhesive tape feeding module achieves stable adhesive tape feeding through structures such as unwinding rollers, adhesive tape guide rollers, and rewinding buffer guide rollers. The adhesive tape cutting module uses a laser cutting head to precisely cut the adhesive tape on the cutting surface. The adhesive tape transfer component uses a lead screw module and a cylinder to drive a vacuum nozzle to pick up and transfer the adhesive tape. At the same time, the moving end of the adhesive tape transfer component drives the guide plate to move when transferring the adhesive tape. In conjunction with the inclined sliding groove of the vertical plate, the cutting surface is turned to the guide roller to quantitatively stretch the adhesive tape and assist the adhesive tape to detach from the release paper. This makes the adhesive tape feeding, cutting, transfer and pasting process precise and continuous, thereby improving the stability of adhesive application.

[0035] 3. The primary vision inspection module captures images of the battery using a vision camera. The image processing unit calculates the angle deviation and outputs a signal. The lifting cylinder of the angle adjustment module lifts the battery, and the stepper motor drives the battery to rotate to a preset angle according to the electrical signal from the primary vision inspection module, thereby achieving precise adjustment of the battery angle and ensuring that the angle between the tape and the battery positioning line meets the requirements.

[0036] 4. The secondary vision inspection module, in conjunction with the secondary lifting cylinder, detects the relative angle between the adhesive tape and the battery after application. The coaxiality vision inspection module detects the coaxiality between the adhesive tape and the battery. This eliminates the need for manual measurement and inspection, thereby saving labor costs and avoiding subjective errors in manual inspection, thus improving product consistency and adhesive application accuracy.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example:

[0049] Please see Figure 1 - Figure 8 This embodiment describes an automatic small round adhesive applicator and method based on batteries, including a mounting plate 100. The mounting plate 100 carries various functional modules. With the help of a rotating disk 101, the battery is transferred between multiple modules, thereby achieving fully automated adhesive application. The overall structure of the equipment includes the mounting plate 100, which is equipped with a feeding module 200, an angle adjustment module 400, an adhesive tape feeding module 500, an adhesive tape cutting module 600, an adhesive tape transfer assembly 700, a discharging module 1000, a primary vision inspection module 300, a secondary vision inspection module 800, and a coaxiality vision inspection module 900. The primary vision inspection module 300 is used to detect the angle of the battery, and the angle adjustment module 400 is used to lift and rotate the battery.

[0050] The mounting plate 100 is also equipped with a rotating disk 101, which is driven by a servo motor to drive the battery to flow between the feeding module 200, the primary vision inspection module 300, the angle adjustment module 400, the tape transfer assembly 700, the secondary vision inspection module 800, the coaxiality vision inspection module 900, and the unloading module 1000.

[0051] The mounting plate 100 is also equipped with a defective product recycling module 1100, which is used to recycle batteries that fail the angle test or the coaxiality test. The defective product recycling module 1100 is equipped with a fourth transfer component and a conveyor belt. The fourth transfer component is used to place the defective products on the turntable onto the conveyor belt, and the conveyor belt sends the defective products to the waste box.

[0052] The rotating disk 101 has multiple battery slots 40 evenly distributed along its edge. Each battery slot 40 is used to accommodate a cylindrical battery. The rotating disk 101 rotates intermittently under the drive of a servo motor. The rotating disk 101 corresponds to multiple stop positions, namely, the loading position, the primary vision inspection position, the adhesive application position, the secondary vision inspection position, the coaxiality inspection position, the unloading position, and the defective product recycling position. The loading position corresponds to the loading module 200, the primary vision inspection position corresponds to the primary vision inspection module 300 and the angle adjustment module 400, the adhesive application position corresponds to the adhesive tape feeding module 500, the adhesive tape cutting module 600 and the adhesive tape transfer assembly 700, the secondary vision inspection position corresponds to the secondary vision inspection module 800, the coaxiality inspection position corresponds to the coaxiality vision inspection module 900, the unloading position corresponds to the unloading module 1000, and the defective product recycling position corresponds to the defective product recycling module 1100.

[0053] After each rotation of the rotating disk 101, a battery slot 40 precisely stops at a stop position, realizing the orderly flow of batteries between modules. The rotating disk 101 is driven by a servo motor to make the battery transfer precise and continuous.

[0054] The adhesive tape feeding module 500 includes a vertical plate 501, an unwinding roller 502, a winding roller 503, a cutting surface 504, multiple adhesive tape pulling guide rollers 505, a winding buffer guide roller 506, and a cutting surface steering guide roller 507. The unwinding roller 502 is installed on the upper side of one side of the vertical plate 501, and the winding roller 503 is installed on the lower side of the vertical plate 501 on the same side as the unwinding roller 502. The cutting surface 504 is fixedly installed on the side of the vertical plate 501 away from the unwinding roller 502. The entire roll of adhesive tape is mounted on the unwinding reel 502. The adhesive tape is drawn out from the unwinding reel 502, guided by the tape guide wheel 505, and reaches the cutting surface 504. After passing through the cutting surface 504, it is turned by the cutting surface turning guide wheel 507 and then laid on the cutting surface 504. The release paper of the adhesive tape is in contact with the cutting surface 504. After the used release paper and waste adhesive tape are drawn out from the cutting surface 504, they are wound onto the take-up reel 503 after passing through the take-up buffer guide wheel 506.

[0055] The cutting surface 504 is used to support the adhesive tape to be cut. Multiple adhesive tape guide wheels 505 are installed in the middle of the side of the upright plate 501. The winding buffer guide wheel 506 is located between the winding wheel 503 and the cutting surface 504. The winding buffer guide wheel 506 is slidably connected to the upright plate 501. The cutting surface turning guide wheel 507 is slidably installed on the side of the upright plate 501 near the cutting surface 504, and is used to turn the adhesive tape after passing through the cutting surface 504 to the winding wheel 503.

[0056] The tape feeding module 500 also includes an upper tape clamping unit 508 and a lower tape clamping unit 509. The upper tape clamping unit 508 is positioned above the cutting surface 504, and the lower tape clamping unit 509 is positioned below the cutting surface 504. The upper tape clamping unit 508 includes a pressing cylinder 5081 and a pressing block 5082, and the lower tape clamping unit 509 includes a clamping cylinder 5091 and a clamping block 5092. The telescopic end of the pressing cylinder 5081 is fixedly connected to the pressing block 5082. The pressing block 5082 and the cutting surface 504 together squeeze the tape to fix the upper end of the tape. The clamping cylinder 5091 drives the two clamping blocks 5092 to move closer to each other and squeeze the lower end of the tape to fix the lower end of the tape. The two work together to ensure the stability of the tape position during cutting.

[0057] The tape cutting module 600 uses laser cutting. The tape cutting module 600 includes an adjustment bracket 601 and a laser cutting head 602. The adjustment bracket 601 is mounted on the mounting plate 100, and the laser cutting head 602 is mounted on the adjustment bracket 601. The laser cutting head 602 is located directly above the cutting surface 504. The adjustment bracket 601 is used to adjust the height of the laser cutting head 602 relative to the cutting surface 504. The laser cutting head 602 cuts out a ring of tape according to a preset program.

[0058] The adhesive tape transfer assembly 700 includes a lead screw module 701, a cylinder 702, and a vacuum nozzle 703. The lead screw module 701 is mounted on the mounting plate 100 via a bracket. The cylinder 702 is vertically mounted on the moving end of the lead screw module 701. The vacuum nozzle 703 is mounted on the piston rod end of the cylinder 702. The cylinder 702 is used to drive the vacuum nozzle 703 to move vertically up and down, so that the vacuum nozzle 703 can press down to the cutting surface 504 to pick up the cut annular adhesive tape and press it down to the surface of the battery positive electrode at the adhesive application position on the rotating disk 101 to complete the adhesion. After the adhesion is completed, the cylinder 702 drives the vacuum nozzle 703 to rise, and the lead screw module 701 drives the cylinder 702 and the vacuum nozzle 703 to return to above the cutting surface 504.

[0059] In addition to transferring the adhesive tape, the adhesive tape transfer assembly 700, in conjunction with the adhesive tape feeding module 500, also has the function of quantitatively stretching the adhesive tape and separating it from the release paper.

[0060] The adhesive tape feeding module 500 has an inclined groove 10 on the side of its upright plate 501 near the cutting surface guide wheel 507. The adhesive tape transfer assembly 700 has a guide plate 20 on the moving end of its screw module 701. An L-shaped guide groove 30 is formed on the side of the guide plate 20 facing the upright plate 501. The L-shaped guide groove 30 includes a horizontal section and a vertical section. The horizontal section of the L-shaped guide groove 30 is parallel to the moving direction of the screw module 701. One end of the cutting surface guide wheel 507 is inserted into the L-shaped guide groove 30 for cutting adhesive tape. One end of the surface-turning guide wheel 507 inserted into the L-shaped guide groove 30 is connected to the guide plate 20 via a spring 60, and the surface-turning guide wheel 507 is slidably connected to the vertical plate 501 via the inclined slide groove 10. One end of the spring 60 is fixed to one end of the surface-turning guide wheel 507 passing through the L-shaped guide groove 30, and the other end is fixed to the guide plate 20. The fixing point of the spring 60 and the guide plate 20 is located on one side of the vertical section of the L-shaped guide groove 30, which is used to pull the surface-turning guide wheel 507 to be stabilized in the inclined slide groove 10.

[0061] When the cylinder 702 of the tape transfer assembly 700 presses down the vacuum nozzle 703 to pick up the cut tape, both the upper tape clamping unit 508 and the lower tape clamping unit 509 clamp the tape. Then, the moving end of the tape transfer assembly 700 moves toward the rotating disk 101. At this time, the upper tape clamping unit 508 is released, and only the lower tape clamping unit 509 clamps the tape.

[0062] When the moving end of the adhesive tape transfer assembly 700 moves toward the rotating disk 101, the adhesive tape transfer assembly 700 drives the guide plate 20 to move. The vertical end of the L-shaped guide groove 30 pushes the cutting surface steering guide wheel 507 to move obliquely downward along the inclined slide 10. When the cutting surface steering guide wheel 507 moves obliquely downward along the inclined slide 10, the adhesive tape is stretched from the upper end. Since the length of the inclined slide 10 and the moving path of the adhesive tape transfer assembly 700 are fixed, the quantitative stretching of the adhesive tape is achieved.

[0063] Meanwhile, as the cutting surface guide wheel 507 stretches the adhesive tape, it drives the adhesive tape to move diagonally downwards, thereby separating the waste adhesive tape from the release paper from the vacuum nozzle 703. That is, the adhesive tape to be transferred separates from the release paper. After the adhesive tape separates from the release paper, the cylinder 702 drives the vacuum nozzle 703 to rise, and the moving end of the adhesive tape transfer assembly 700 continues to drive the adhesive tape to move towards the rotating disk 101.

[0064] The horizontal section of the L-shaped guide groove 30 is aligned with the lower end of the inclined slide 10. When the cutting surface steering guide wheel 507 moves to the horizontal section of the L-shaped guide groove 30, the moving end of the adhesive tape transfer assembly 700 can continue to move toward the rotating disk 101.

[0065] When the guide wheel 507 of the cutting surface moves to the horizontal section of the L-shaped guide groove 30, the moving end of the tape transfer assembly 700 continues to move towards the rotating disk 101. The cylinder 702 drives the vacuum nozzle 703 to rise and then press down to stick the tape to the positive terminal of the battery. After the tape is pasted, the upper clamping unit 508 clamps the tape and the lower clamping unit releases it, and the tape transfer assembly 700 can move towards the cutting surface 504.

[0066] As the tape transfer assembly 700 moves toward the cutting surface 504, the spring 60 pulls the cutting surface steering guide wheel 507, causing the cutting surface steering guide wheel 507 to move relative to the guide plate 20. The cutting surface steering guide wheel 507 moves closer to the vertical end of the L-shaped guide groove 30. When the cutting surface steering guide wheel 507 reaches the vertical end of the L-shaped guide groove 30, the vertical end of the L-shaped guide groove 30 pushes the cutting surface steering guide wheel 507 to move upward along the inclined slide 10. During this process, the tape clamping unit 509 below the tape releases the lower end of the tape, while the tape clamping unit 508 above the tape continues to clamp the tape. The winding buffer guide wheel 506 slides downward due to its own weight, thereby pulling the tape toward the winding wheel 503, and then the winding wheel 503 tightens it.

[0067] One end of the spring 60 is fixed to the end of the rubber-cutting surface steering guide wheel 507 that passes through the L-shaped guide groove 30, and the other end of the spring 60 is fixed to the guide plate 20. The fixing point of the spring 60 and the guide plate 20 is located on one side of the vertical section of the L-shaped guide groove 30. The spring 60 is used to pull the rubber-cutting surface steering guide wheel 507, so that when the rubber-cutting surface steering guide wheel 507 is at the lower end of the inclined slide 10, in addition to being limited by the horizontal section of the L-shaped guide groove 30 and the inclined slide 10, it is also subjected to the pulling force of the spring 60, so that the rubber-cutting surface steering guide wheel 507 is closer to the lower end of the inclined slide 10, thereby stabilizing the rubber-cutting surface steering guide wheel 507 in the slide. The spring 60 shown in the figure is located on the back of the guide plate 20.

[0068] After the guide wheel 507 of the cutting surface is located at the lower end of the inclined slide 10 and the moving end of the tape transfer assembly 700 is disengaged from the cutting surface 504, the tape cutting module 600 can start cutting the tape. During the cutting process, the tape clamping unit 508 above the tape and the tape clamping unit 509 below the tape clamp and fix the tape.

[0069] When the take-up buffer guide wheel 506 moves downward and triggers the proximity sensor, the take-up wheel 503 rotates at a set angle to ensure that the tape is not too tight. At the same time, the unwind wheel 502 is provided with a torsion spring 60 at one end passing through the vertical plate 501. When the tape is pulled, the torsion spring 60 twists and releases the tape. After the torque sensor detects the preset torque, the unwind wheel 502 rotates at a set angle to ensure that the tape is properly tensioned.

[0070] The angle adjustment module 400 includes a lifting cylinder 401, a stepper motor 402, and a suction nozzle 403. The angle adjustment module 400 is located directly below the primary vision inspection module 300. The lifting cylinder 401 is vertically arranged, the stepper motor 402 is installed at the end of the lifting cylinder 401, and the suction nozzle 403 is installed on the telescopic shaft of the lifting cylinder 401. The suction nozzle 403 is used to adsorb and fix the battery to prevent the battery from shifting when adjusting the angle. The primary vision inspection module 300 has a built-in vision camera and image processing unit for accurately detecting battery angle deviation.

[0071] When the rotating disk 101 drives the battery to rotate to the first visual inspection position and stops, the lifting cylinder 401 of the angle adjustment module 400 first drives the piston rod to rise, which in turn drives the suction nozzle 403 to rise. The suction nozzle 403 picks up the battery and lifts it out of the battery slot 40 of the rotating disk 101. Then, the vision camera of the first visual inspection module 300 captures an image of the battery. The image processing unit analyzes the image, identifies the position of the positioning line on the side wall of the battery, calculates the deviation between the current angle of the battery and the preset angle, generates an angle adjustment electrical signal and transmits it to the angle adjustment module 400. After receiving the electrical signal, the stepper motor 402 drives the battery to rotate to the preset angle. After the angle adjustment is completed, the lifting cylinder 401 drives the piston rod to descend and put the battery back into the battery slot 40 of the rotating disk 101. This achieves synchronous linkage between angle adjustment and first visual inspection, ensuring that the angle between the adhesive tape and the battery positioning line meets the requirements when applying adhesive later.

[0072] In addition, a secondary lifting cylinder 50 is located directly below the secondary visual inspection module 800. The secondary lifting cylinder 50 is used to lift the battery. The secondary visual inspection module 800 is used to detect the relative angle between the pasted battery and the adhesive tape. The coaxiality visual inspection module 900 is used to detect the coaxiality between the pasted battery and the adhesive tape. The two work together with the rotating disk 101 to further verify the quality of the adhesive application.

[0073] Visual intelligence algorithms are used in the primary visual inspection module 300, the secondary visual inspection module 800, and the coaxiality visual inspection module 900. These are commonly used methods and will not be elaborated upon here.

[0074] The No. 1, No. 3, and No. 4 transfer components each contain a lead screw, a cylinder, and grippers / nozzles. The suction cups or grippers in the transfer components are driven by the lead screw to move horizontally, and the suction nozzles or grippers are driven by the cylinder to move vertically.

[0075] A battery-based automatic method for applying small round adhesive strips includes the following steps:

[0076] S1: Loading operation: Place the box containing cylindrical batteries into the loading module 200. The loading module 200 is equipped with a first transfer component. Through the horizontal movement and vertical lifting of the first transfer component, the batteries in the box are transferred to the battery slot 40 of the loading position of the rotating disk 101. The box only needs to be placed into the loading module 200 manually. The first transfer component realizes precise horizontal and vertical movement, improving loading efficiency.

[0077] S2: Primary Visual Inspection and Angle Adjustment: The servo motor drives the rotating disk 101 to rotate, transferring the battery in the battery slot 40 to the primary visual inspection position and stopping. The lifting cylinder 401 of the angle adjustment module 400 rises, lifting the battery. The primary visual inspection module 300 captures an image of the battery and calculates the angle deviation, outputting an electrical signal to the stepper motor 402. The stepper motor 402 drives the battery to rotate to the appropriate angle. The lifting cylinder 401 descends to put the battery back into the battery slot 40. Through automated inspection and adjustment, the error of manual angle judgment is avoided, ensuring that the angle of each battery is consistent.

[0078] S3: Adhesive Tape Feeding and Cutting: The unwinding roller 502 of the adhesive tape feeding module 500 unwinds the tape. After being guided by the tape pulling guide roller 505, the winding buffer guide roller 506, and the cutting surface turning guide roller 507, the tape is laid on the cutting surface 504. The tape clamping unit 508 above the tape and the tape clamping unit 509 below the tape clamp the tape. The laser cutting head 602 of the adhesive tape cutting module 600 cuts the tape according to a preset program. The guide roller ensures smooth tape feeding, and the clamping unit fixes the tape. Compared with punching, laser cutting has lower vibration to the overall equipment and less impact on other steps.

[0079] S4: Adhesive application and inspection operation: The rotating disk 101 transfers the battery after angle adjustment to the adhesive application position and stops. The adhesive tape transfer component 700 transfers the cut ring-shaped adhesive tape to the positive electrode surface of the battery. Then the rotating disk 101 continues to drive the battery to rotate. The secondary visual inspection position and the coaxiality inspection position check whether the battery adhesive tape is qualified.

[0080] S5: Unloading and Defective Product Recycling: The rotary table 101 transfers the batteries to the unloading position or the defective product recycling position. If the batteries are qualified, the third transfer component of the unloading module 1000 transfers them to the unloading box. The unloading module 1000 then places the batteries into the tray, and the entire tray of batteries is manually removed. If the batteries are defective, the fourth transfer component of the defective product recycling module 1100 transfers them to the waste box. The defective product recycling module 1100 then transfers the defective batteries into the waste box, thus achieving automatic sorting of qualified and defective products and reducing manual screening costs.

[0081] S6: Repeat steps S1-S5 to achieve continuous adhesive application.

[0082] The advantages of this method are: a high degree of automation throughout the process, replacing manual feeding, adhesive application, inspection and sorting, avoiding problems such as misalignment and poor adhesion caused by human fatigue, improving product consistency, and coordinated operation of various modules, such as the linkage of adhesive tape feeding-cutting-transfer and visual inspection-angle adjustment. Compared with manual adhesive application, the efficiency of automated operation is significantly improved, and the adhesive application quality is ensured and the defect rate is reduced through primary angle inspection, secondary angle inspection and coaxiality inspection.

[0083] A battery-based automatic method for applying small round adhesive strips, wherein S4 includes the following steps:

[0084] S41: The servo motor drives the rotating disk 101 to transfer the angle-adjusted battery to the adhesive application position and stop. The lead screw module 701 of the adhesive transfer assembly 700 drives the cylinder 702 and the vacuum nozzle 703 to move above the adhesive cutting surface 504. The cylinder 702 descends and the vacuum nozzle 703 picks up the annular adhesive tape. At this time, the upper clamping unit 508 of the adhesive tape is released. Then the lead screw module 701 drives the adhesive tape to move directly above the battery. The cylinder 702 descends and sticks the adhesive tape to the positive electrode surface of the battery. Then the upper clamping unit 508 of the adhesive tape clamps, and the lower clamping unit 509 of the adhesive tape releases. Then the adhesive transfer assembly 700 resets.

[0085] During the tape transfer process of the tape transfer assembly 700, the moving end of the tape transfer assembly 700 drives the guide plate 20 to move. The guide plate 20 and the inclined slide 10 drive the cutting surface steering guide wheel 507 to move downwards in a direction away from the cutting surface 504. During each tape application operation, the cutting surface steering guide wheel 507 moves an equal distance along the inclined slide 10, thereby quantitatively stretching the tape. During the reset process of the tape transfer assembly 700, the winding buffer guide wheel 506 moves downwards, pulling the waste tape and release paper toward the winding wheel 503, and then the winding wheel 503 tightens it.

[0086] Furthermore, during the process of stretching the adhesive tape by the cutting surface steering guide wheel 507, the cutting surface steering guide wheel 507 drives the adhesive tape to move obliquely downward, thereby causing the waste adhesive tape and release paper to separate from the vacuum suction nozzle 703. That is, the adhesive tape to be transferred separates from the release paper. At this time, the cylinder 702 drives the vacuum suction nozzle 703 to rise, and the moving end of the adhesive tape transfer assembly 700 continues to drive the adhesive tape to move towards the rotating disk 101. When it is above the battery, the vacuum suction nozzle 703 descends, thereby realizing the integration of separating the adhesive tape to be transferred from the release paper, transferring the adhesive tape, quantitative adhesive supply and waste adhesive recycling.

[0087] S42: Secondary visual inspection: The rotating disk 101 transfers the battery after adhesive application to the secondary visual inspection position and stops. The secondary lifting cylinder 50 below the secondary visual inspection module 800 rises and lifts the battery. The secondary visual inspection module 800 detects the angle between the adhesive tape and the battery positioning line. Unqualified batteries are marked as defective products. The secondary visual inspection module 800 detects the angle deviation of the adhesive tape after application.

[0088] S43: Coaxiality Detection: The rotating disk 101 transfers the battery to the coaxiality detection position and stops. The coaxiality visual inspection module 900 captures an image of the battery and compares the position of the tape with the outer edge of the battery to detect coaxiality. Unqualified batteries are marked as defective products. The coaxiality detection ensures that the tape is pasted in the center to avoid misalignment.
