Description

Technical Field

[0001] This utility model relates to the field of photovoltaic busbar technology, and in particular to an automatic winding machine adhesive applicator. Background Technology

[0002] With the development of the photovoltaic industry, photovoltaic busbars need to be fixed with tape during the connection of solar cells to ensure reliable adhesion between the busbar and the cells. Currently, the tape application process is mostly completed using automated equipment. This equipment achieves the bonding of the tape and busbar through steps such as conveying, pressing, positioning, and applying the tape. Such equipment typically includes a tape conveying unit, an application unit, and a winding unit, aiming to improve production efficiency and application accuracy.

[0003] Existing tape-applying devices are prone to belt misalignment during conveying due to slight differences in belt thickness or factors such as tension fluctuations and guide wheel installation deviations. This misalignment not only disrupts the belt's straightness but may also cause wrinkles on the belt surface or even belt deviation, resulting in the belt rolling or tearing inside the reel. In severe cases, it may even lead to the scrapping of the entire belt, increasing production losses. Utility Model Content

[0004] The purpose of this invention is to provide an automatic rewinding machine adhesive applicator that can adapt to minor deviations in tape thickness and position, and prevent tape from wrinkling or running off-track during transport.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic winding machine adhesive applicator includes a base and an adhesive applicator base plate disposed on the base. The adhesive applicator base plate is sequentially provided with a lead-out reel, a lead-through roller assembly, an adhesive applicator mechanism, a pressure roller, and a take-up reel. The lead-through roller assembly is used to guide the tape from the lead-out reel through the adhesive applicator mechanism to the take-up reel. The adhesive applicator base plate is provided with a take-up motor and a pressure roller motor. The output end of the take-up motor is connected to the take-up reel, and the output end of the pressure roller motor is connected to the pressure roller. The take-up reel and the pressure roller are suspended on the adhesive applicator base plate by a floating component.

[0006] By adopting the above technical solution, the smooth transmission of the tape can be achieved. The take-up motor and the pressure motor drive the take-up reel and the pressure reel to rotate respectively, ensuring that the tape maintains tension during operation. The take-up reel and the pressure reel can float in a direction perpendicular to the adhesive base plate, which can adapt to slight deviations in tape thickness and position, and prevent the tape from wrinkling or running off-track during the conveying process.

[0007] A further feature of this invention is that the floating component includes a first elastic element and a second elastic element; the first elastic element is sleeved on the output shaft of the take-up motor, and the outer end of the first elastic element abuts against the take-up reel, so that the take-up reel tends to move away from the adhesive base plate; the second elastic element is sleeved on the output shaft of the pressing motor, and the outer end of the second elastic element abuts against the pressing reel, so that the pressing reel tends to move away from the adhesive base plate.

[0008] By adopting the above technical solution, the take-up reel and the pressure reel can generate buffer when subjected to external pressure or changes in tape tension. The first elastic element and the second elastic element ensure that the take-up reel and the pressure reel always tend to move away from the adhesive base plate. This allows for automatic adjustment of the clamping force when the tape thickness changes or the position shifts, further improving the smoothness of tape conveying.

[0009] A further feature of this invention is that a straightening mechanism is provided on one side of the pressure plate. The straightening mechanism includes a fixed bracket, a movable frame, and a straightening wheel assembly disposed on the movable frame. A straightening belt is wrapped around the outer periphery of the straightening wheel assembly, and the straightening belt is in close contact with the pressure plate.

[0010] By adopting the above technical solution, the tape can be pressed and straightened before winding by the tight fit between the straightening belt and the take-up reel, ensuring that the tape is upright during transmission and preventing wrinkled excess material from rolling or tearing in the reel.

[0011] A further feature of this invention is that a straightening elastic element is provided between the movable frame and the fixed support, and the straightening elastic element is used to drive the movable frame away from the fixed support.

[0012] By adopting the above technical solution, a straightening elastic element is set between the fixed bracket and the movable frame, so that the movable frame can be adjusted within a certain range, making it convenient for staff to adjust the clamping force.

[0013] A further feature of this invention is that the adhesive applicator includes an adjusting cylinder, an adhesive applicator wheel mounted on the adjusting cylinder, and a strip plate fixed to the bottom of the adhesive applicator base plate, with one end of the strip plate abutting against the adhesive applicator wheel.

[0014] By adopting the above technical solution, the tape distributor presses the tape tightly onto the tape applicator, so that the tape can be firmly attached to the photovoltaic busbar on the tape applicator, thereby completing the tape applicator process of the photovoltaic busbar.

[0015] A further feature of this invention is that the cable tray is connected to the adhesive base plate via a rotating shaft, and a third elastic element is sleeved on the rotating shaft. The outer end of the third elastic element abuts against the cable tray, so that the cable tray tends to move away from the adhesive base plate.

[0016] By adopting the above technical solution, after the tape is applied, it is output from the output tray. The output tray can automatically adjust its position according to the tape winding amount and tension, avoiding tape breakage due to excessive tension and ensuring more convenient subsequent tape application.

[0017] A further feature of this invention is that the wire guide wheel assembly includes a first feeding guide wheel, a second feeding guide wheel, a first adhesive application guide wheel, a second adhesive application guide wheel, a first unloading guide wheel, and a second unloading guide wheel sequentially arranged on the adhesive application base plate. The first unloading guide wheel and the second unloading guide wheel are located between the pressure plate and the adhesive application mechanism. The first adhesive application guide wheel and the second adhesive application guide wheel are located on both sides of the tape separating plate. The first feeding guide wheel and the second feeding guide wheel are located between the adhesive application mechanism and the wire exit plate.

[0018] By adopting the above technical solution, the guide roller assembly adopts a multi-stage guiding structure. After passing through the first and second feeding guide rollers, the tape enters the tape application mechanism. The first and second tape application guide rollers achieve precise positioning, and finally the tape enters the output tray through the first and second feeding guide rollers. This effectively prevents the tape from swinging or slipping during transmission, ensures the accuracy of the tape application position, reduces the frequency of manual adjustment, and improves production efficiency.

[0019] A further feature of this invention is that: the adjusting cylinder is provided with a vertically movable lifting plate, a support plate is connected to the lifting plate, the adhesive-applying wheel is rotatably connected to the support plate, and an adhesive-applying elastic element is provided between the lifting plate and the support plate, the adhesive-applying elastic element being used to make the adhesive-applying wheel tend to move away from the lifting plate.

[0020] By adopting the above technical solution, the lifting plate in the cylinder can drive the adhesive roller to achieve vertical adjustment, and the adhesive roller is provided with buffer force by the adhesive elastic element, so that the adhesive roller can automatically adjust the pressure when in contact with the tape, ensuring the stability of the bonding effect, avoiding damage to the manifold, and adapting to tapes of different thicknesses.

[0021] A further feature of this invention is that an optical sensor is provided between the first adhesive-applying guide wheel and the second feeding guide wheel.

[0022] By adopting the above technical solution, the position and running status of the tape can be detected in real time, and control signals can be fed back in a timely manner to adjust the motor speed or stop the operation, thereby preventing the tape from breaking, running off track or getting tangled.

[0023] A further feature of this invention is that: a lead screw is provided on the base, a movable block is threadedly connected to the lead screw, the adhesive base plate is fixed on the movable block, and an adjustment motor for driving the lead screw to rotate is provided on the base.

[0024] By adopting the above technical solution, the adhesive base plate can be moved precisely in the vertical direction, enabling the adhesive application device to be finely adjusted throughout the photovoltaic busbar processing equipment, thus meeting different production needs.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. Both the take-up reel and the pressure reel have a floating structure and are equipped with elastic components, which can automatically adjust the pressure on the tape, reducing the risk of wrinkles and deviation caused by thickness differences or positional shifts during the conveying process.

[0027] 2. The straightening mechanism can adjust the clamping force within a certain range, making it convenient for operators to adjust and adapt to different tape specifications.

[0028] 3. This utility model adopts a multi-stage guiding design, combined with the adjusting cylinder and the tape-distributing plate in the adhesive applicator, to achieve stable position of the tape during the adhesive applicator process and ensure accurate application.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 3As shown, this utility model discloses an automatic winding machine adhesive applicator, comprising a base 1 and an adhesive applicator base plate 2 mounted on the base 1. A lead screw 11 is mounted on the base 1, and a movable block 12 is threadedly connected to the lead screw 11. The adhesive applicator base plate 2 is fixed to the movable block 12. An adjusting motor for driving the lead screw 11 to rotate is also provided on the base 1. Through the lead screw 11 mechanism, the adhesive applicator base plate 2 can move precisely in the vertical direction, achieving fine-tuning of the height of the adhesive applicator on the entire photovoltaic busbar processing equipment. The adhesive applicator base plate 2 is sequentially provided with a wire outlet plate 8, a wire guide wheel group 5, an adhesive applicator mechanism 6, and a wire pressing plate. 4 and take-up reel 3, and the guide roller group 5 are used to guide the tape from the exit reel 8 through the adhesive applicator 6 to the take-up reel 3. The adhesive applicator base plate 2 is equipped with a take-up motor 31 and a pressure motor 41. The output end of the take-up motor 31 is connected to the take-up reel 3, and the output end of the pressure motor 41 is connected to the pressure motor 4. The take-up reel 3 and the pressure motor 4 are suspended on the adhesive applicator base plate 2 by a floating component to ensure the stability of the tape during the transmission process. The take-up motor 31 and the pressure motor 41 drive the take-up reel 3 and the pressure motor 4 to rotate respectively, so that the tape always maintains appropriate tension and avoids wrinkles or deviation.

[0035] like Figure 1 and Figure 2 As shown, the floating assembly includes a first elastic element 32 and a second elastic element 42. The first elastic element 32 is sleeved on the output shaft of the take-up motor 31, and the outer end of the first elastic element 32 abuts against the take-up reel 3, causing the take-up reel 3 to tend to move away from the adhesive base plate 2. The second elastic element 42 is sleeved on the output shaft of the pressure motor 41, and the outer end of the second elastic element 42 abuts against the pressure plate 4, causing the pressure plate 4 to tend to move away from the adhesive base plate 2. When subjected to external pressure or changes in tape tension, the take-up reel 3 and the pressure plate 4 can generate buffering and automatically adjust the clamping force to adapt to small deviations in tape thickness or position, making transmission smoother.

[0036] like Figure 1 As shown, a straightening mechanism 7 is provided on one side of the pressure plate 4. The straightening mechanism 7 includes a fixed bracket 71, a movable frame 72, and a straightening wheel assembly 73 set on the movable frame 72. The straightening wheel assembly 73 includes two straightening wheels, and a straightening belt 74 is wrapped around the outer circumference of the two straightening wheels. The middle end of the straightening belt 74 near the pressure plate 4 is pressed against the pressure plate 4, thereby generating a pressing force on the tape on the pressure plate 4. Through this structure, the tape can be pressed and straightened before entering the guide wheel assembly 5, ensuring that the tape maintains a flat posture during transmission and reducing defects such as bubbles and wrinkles during transmission. A straightening elastic element 75 is provided between the movable frame 72 and the fixed bracket 71. The straightening elastic element 75 is used to drive the movable frame 72 away from the fixed bracket 71, so that the straightening mechanism 7 can adjust the pressing force within a certain range, which is convenient for operators to adjust and adapt to different tape specifications.

[0037] like Figure 1As shown, the adhesive application mechanism 6 includes an adjusting cylinder 61, an adhesive application wheel 62 rotatably mounted on the adjusting cylinder 61, and a tape distribution plate 63 fixed to the bottom of the adhesive application base plate 2. One end of the tape distribution plate 63 presses the adhesive tape firmly onto the adhesive application wheel 62, allowing the tape to adhere firmly to the surface of the photovoltaic busbar, thus completing the adhesive application process. The adjusting cylinder 61 is equipped with a vertically movable lifting plate 611, on which a support plate 612 is connected. The adhesive application wheel 62 is mounted on the support plate 612. An adhesive application elastic element 613 is provided between the lifting plate 611 and the support plate 612 to allow the adhesive application wheel 62 to tend to move away from the lifting plate 611, thereby providing cushioning during the adhesive application process, preventing excessive pressure from damaging the busbar, and accommodating the needs of tapes of different thicknesses.

[0038] like Figure 1 and Figure 3 As shown, the cable tray 8 is connected to the adhesive base plate 2 via a rotating shaft 81. A third elastic element 82 is sleeved on the rotating shaft 81. The outer end of the third elastic element 82 abuts against the cable tray 8, causing the cable tray 8 to tend to move away from the adhesive base plate 2. The cable tray 8 can automatically adjust its position according to the amount of tape winding and the tension, ensuring a smooth output process and avoiding tape breakage or deviation due to excessive tension.

[0039] like Figure 1 As shown, the guide roller group 5 includes a first feeding guide roller 56, a second feeding guide roller 55, a first adhesive application guide roller 54, a second adhesive application guide roller 53, a first unloading guide roller 52, and a second unloading guide roller 51. The first unloading guide roller 52 and the second unloading guide roller 51 are disposed between the pressure plate 4 and the adhesive application mechanism 6. The first adhesive application guide roller 54 and the second adhesive application guide roller 53 are disposed on both sides of the tape separating plate 63. The first feeding guide roller 56 and the second feeding guide roller 55 are disposed between the adhesive application mechanism 6 and the output reel 8. The tape passes sequentially through the output reel 8, the first feeding guide roller 56, the second feeding guide roller 55, the first adhesive application guide roller 54, the adhesive application mechanism 6, the first unloading guide roller 52, the second unloading guide roller 51, the pressure plate 4, and the take-up reel 3. Through multi-stage guidance, the tape can achieve precise positioning during transmission, avoid swaying or slipping, ensure the accuracy of the adhesive application position, reduce manual intervention, and improve production efficiency.

[0040] like Figure 1 As shown, an optical sensor 9 is provided between the first adhesive guide wheel 54 and the second feeding guide wheel 55. The optical sensor 9 is used to detect the position and running status of the tape in real time and feed the signal back to the control system so as to adjust the motor speed or execute the shutdown to prevent the tape from breaking, running off track or getting tangled.

[0041] The working principle of this utility model is as follows: the lead screw 11 drives the movable block 12 to move, the adhesive base plate 2 is fixed on the movable block 12, and the adjusting motor drives the lead screw 11 to rotate, thereby realizing the horizontal position adjustment of the adhesive base plate 2. When the device is started, the output disc 8 outputs the tape along a fixed path, and at the same time, under the action of the third elastic element 82, it can float in a direction perpendicular to the adhesive base plate 2 to maintain stability during the movement. After the tape is output from the output disc 8, it passes through the first feeding guide wheel 56 and the second feeding guide wheel 55 in sequence and enters the adhesive application mechanism 6. The lifting plate 611 moves vertically under the drive of the adjusting cylinder 61. The support plate 612 is connected to the lifting plate 611, and the adhesive application wheel 62 is set on the support plate 612 and is in close contact with the tape separating plate 63 under the action of the adhesive application elastic element 613. When the tape passes through the adhesive roller 62, the tape separating plate 63 separates the tape, completing the tape bonding. After the tape passes through the adhesive roller 62 and the separating plate 63, it continues to pass through the second adhesive guide roller 53, the first feeding guide roller 52 and the second feeding guide roller 51, and is further pressed by the pressure plate 4. The pressure plate 4 is driven by the pressure motor 41 and can float in a direction perpendicular to the adhesive base plate 2 under the action of the second elastic element 42. The tape is straightened between the pressure plate 4 and the straightening mechanism 7. The part of the straightening belt 74 located between the two pressure rollers is pressed tightly with the pressure plate 4, pressing the tape onto the pressure plate 4. After the tape passes through the straightening mechanism 7, the tape is finally guided to the take-up reel 3. The take-up reel 3 floats in a vertical direction under the action of the first elastic element 32 to maintain the stability of the winding.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
