Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a bonding device and photovoltaic cell production equipment. Background Technology

[0002] As part of the photovoltaic industry, perovskite has attracted much attention due to its potential for high efficiency and low cost, and its development has been rapid in recent years. Although perovskite is an emerging material with a short development history and is far less mature than crystalline silicon products, the stability and efficiency of the product itself have become key factors in market competition.

[0003] In the existing manufacturing process of perovskite thin-film photovoltaic modules, thin-film chips are used as the substrate. Insulating tape is first applied to the surface of the back electrode film layer by rolling. Then, busbars are applied on the insulating tape to lead out the current. Conductive tape is applied to the positive and negative electrodes of the battery on both sides to transmit the current. Butyl glue is applied around the perimeter, and an encapsulating film is used in the middle for lamination and encapsulation.

[0004] Existing bonding devices apply the insulating tape directly above the battery chip's film layer using bonding rollers. The rollers exert a pulling force on the film layer during bonding, increasing the risk of film detachment. Furthermore, the upward pulling force during the folding motion of the busbar also pulls the insulating tape, further increasing the risk of film detachment. To ensure product stability, currently only about 12mm of the battery area is removed, ensuring the insulating tape adheres only to the glass surface and not to the thin-film battery layer, thus avoiding film detachment. However, this method also reduces the effective power generation area of ​​the battery, affecting overall power generation efficiency. Utility Model Content

[0005] In view of this, the present invention provides a bonding device and photovoltaic cell production equipment to solve the problem that existing bonding devices may cause the cell chip film layer to fall off or affect the effective power generation area of ​​the cell.

[0006] In a first aspect, this utility model provides an application device, including an application platform, an insulating tape feeding mechanism, a busbar feeding and application mechanism, and an insulating busbar picking mechanism. The application platform is equipped with a first adsorption mechanism for adsorbing and fixing the insulating tape onto the application platform; the insulating tape feeding mechanism includes an insulating tape release paper receiving tray and an insulating tape feeding tray respectively disposed at both ends of the application platform; the busbar feeding and application mechanism is disposed above the application platform and is adapted to move along the extension direction of the insulating tape; the busbar feeding and application mechanism includes a busbar feeding tray and a busbar application pressure roller, the busbar application pressure roller being disposed in the discharge direction of the busbar feeding tray, adapted to press and fix the busbar onto the adhesive surface of the insulating tape to obtain an insulating busbar; the insulating busbar picking mechanism is disposed above the application platform and is adapted to pick up and place the insulating busbar.

[0007] Beneficial Effects: The applicator provided in this embodiment of the invention pre-attaches and connects the busbar and insulating tape to form an insulating busbar, which is then applied to the battery chip. This allows for rolling only on the adhesive surface of the insulating tape, avoiding direct contact with the battery film layer and thus preventing pulling forces and film detachment. Because the busbar is pre-attached to the insulating tape, the folding action of the busbar is also pre-completed, eliminating the risk of film detachment caused by direct bending on the film surface.

[0008] Furthermore, the insulating busbar obtained by the application device provided by this utility model can be directly applied to the battery chip. Since it will not cause the cell film layer to fall off, there is no need to remove the battery area of ​​about 12mm in the middle, thus preserving the complete battery area. This can maximize the effective power generation area of ​​the battery, improve the overall power generation efficiency, and also improve the appearance of the product.

[0009] The applicator provided by this utility model realizes the online integrated applicator operation of insulating tape and busbar, and the entire process does not require interruption of production cycle, thus maintaining efficient continuous production.

[0011] In one optional embodiment, the busbar feeding and applying mechanism further includes a movable base and a movable module. The busbar feeding tray and the busbar applying pressure roller are both mounted on the movable base. The movable module and the movable base are connected and adapted to drive the movable base to move along the extension direction of the insulating tape.

[0012] In one optional embodiment, the busbar feeding and applying mechanism further includes a busbar straightening device and a busbar guide groove, which are sequentially arranged between the busbar feeding tray and the busbar applying pressure roller along the busbar discharge direction.

[0013] In one optional embodiment, the busbar feeding and application mechanism further includes busbar cutting scissors, which are disposed between the busbar feeding tray and the busbar application pressure roller, and are close to the busbar application pressure roller.

[0014] In one optional embodiment, the busbar feeding and application mechanism further includes a busbar folding A pressing fixture and a busbar folding A rod, which are disposed on a movable seat with adjustable spacing relative to the application platform.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, in a first aspect, an applicator is provided, comprising an applicator platform 1, an insulating tape feeding mechanism 2, a busbar feeding and applicator 3, and an insulating busbar picking mechanism 4. The application platform 1 is provided with a first adsorption mechanism 11, which is used to adsorb and fix the insulating tape 10 onto the application platform 1; the insulating tape feeding mechanism 2 includes an insulating tape release paper receiving tray 21 and an insulating tape feeding tray 22 respectively disposed at both ends of the application platform 1; the busbar feeding and application mechanism 3 is disposed above the application platform 1 and is adapted to move along the extension direction of the insulating tape 10; the busbar feeding and application mechanism 3 includes a busbar feeding tray 31 and a busbar application pressure roller 32, the busbar application pressure roller 32 is disposed in the discharge direction of the busbar feeding tray 31, and is adapted to press and fix the busbar 20 onto the adhesive surface of the insulating tape 10 to obtain the insulating busbar 30; the insulating busbar picking mechanism 4 is disposed above the application platform 1 and is adapted to pick up and put down the insulating busbar 30.

[0037] The application platform 1 provides the main support workbench, and the feeding of the insulating tape 10 and the application of the busbar 20 are both completed on the application platform 1. By setting a first adsorption mechanism 11 on the application platform 1, the insulating tape 10 is pre-adsorbed and fixed on the platform, so that the insulating tape 10 remains stable during the application process, which facilitates the subsequent application of the busbar 20.

[0038] In the insulating tape feeding mechanism 2, the insulating tape release paper receiving tray 21 and the insulating tape feeding tray 22 are respectively located at both ends of the application platform 1. The insulating tape feeding tray 22 is used for feeding the insulating tape 10, and the insulating tape release paper receiving tray 21 is used for receiving the insulating tape release paper. While waiting for the busbar 20 to be applied, the insulating tape 10 is taut between the insulating tape release paper receiving tray 21 and the insulating tape feeding tray 22, and is fixedly adsorbed onto the application platform 1 by the first adsorption mechanism 11. In some embodiments, the top surfaces of both the insulating tape release paper receiving tray 21 and the insulating tape feeding tray 22 are lower than the surface of the application platform 1. This ensures that when the insulating tape 10 is taut between the insulating tape release paper receiving tray 21 and the insulating tape feeding tray 22, the insulating tape 10 can adhere tightly to the application platform 1.

[0039] In the busbar feeding and applying mechanism 3, the busbar feeding tray 31 is used for feeding the busbar 20. The busbar 20 output from the busbar feeding tray 31 extends to the busbar applying pressure roller 32. Since the busbar feeding and applying mechanism 3 can move along the extension direction of the insulating tape 10, it can move from one end of the applying platform 1 to the other end. During the movement of the busbar feeding and applying mechanism 3, the busbar applying pressure roller 32 rolls and presses the busbar 20 tightly onto the adhesive surface of the insulating tape 10. During the process of the busbar feeding and applying mechanism 3 moving from one end of the applying platform 1 to the other end, the busbar 20 is pressed and fixed onto the insulating tape 10 during the output process, thus obtaining the insulating busbar 30.

[0040] The insulating busbar picking mechanism 4 can pick up the insulating busbar 30 and transfer the insulating busbar 30 onto the battery chip 40.

[0041] The applicator provided in this embodiment of the invention pre-attaches and connects the busbar 20 and the insulating tape 10 to form an insulating busbar 30, and then places the insulating busbar 30 on the battery chip 40. This way, the rolling operation is performed only on the adhesive surface of the insulating tape 10, avoiding direct contact with the battery film layer, thus avoiding pulling forces on the battery film layer and preventing film layer detachment. Since the busbar 20 is pre-attached to the insulating tape 10, the folding action of the busbar 20 is also pre-completed. Therefore, this invention also eliminates the risk of the battery cell film layer detaching due to the folding action directly on the film surface.

[0042] Furthermore, the insulating busbar 30 obtained by the application device provided by this utility model can be directly applied to the battery chip 40. Since it will not cause the cell film layer to fall off, there is no need to remove the battery area of ​​about 12mm in the middle, thus preserving the complete battery area. This can maximize the effective power generation area of ​​the battery, improve the overall power generation efficiency, and also improve the appearance of the product.

[0043] The applicator provided by this utility model realizes the online integrated applicator operation of insulating tape 10 and busbar 20. The entire process does not require interruption of production cycle and maintains efficient continuous production.

[0044] In summary, the bonding device provided by this utility model effectively solves the problem of cell film layer detachment in the manufacturing of existing perovskite thin-film photovoltaic modules, significantly improves the effective power generation area and production efficiency of the battery, and enhances the stability and reliability of the product.

[0045] In some embodiments, the first adsorption mechanism 11 includes a vacuum suction cup with its adsorption port facing upwards. This allows it to adsorb the insulating tape 10.

[0046] In some embodiments, the busbar feeding and applying mechanism 3 further includes a movable base 38 and a movable module. The busbar feeding tray 31 and the busbar applying pressure roller 32 are both disposed on the movable base 38. The movable module is connected to the movable base 38 and is adapted to drive the movable base 38 to move along the extension direction of the insulating tape 10.

[0047] In this embodiment, by setting up a moving module, the movement of the moving seat 38 can be powered, improving the level of automation and reducing manual intervention. The moving module can drive the moving seat 38 to move smoothly along the extension direction of the insulating tape 10, ensuring that the busbar application roller 32 applies uniform pressure throughout the application process, avoiding excessive or insufficient local pressure, thereby improving the adhesion effect between the insulating tape 10 and the busbar 20. The moving module can be flexibly adjusted according to different sizes of insulating tape 10, enabling the equipment to adapt to the production needs of various specifications of products. This flexibility not only improves the versatility of the equipment but also reduces the changeover cost of the production line.

[0048] Specifically, the moving module can be set to move horizontally, or it can also move vertically, so that the application position of the busbar 20 can be flexibly adjusted.

[0049] The moving module can be a telescopic cylinder or a threaded screw pair.

[0050] In some embodiments, the busbar feeding and applying mechanism 3 further includes a busbar straightening device 33 and a busbar guide groove 34, which are arranged sequentially between the busbar feeding tray 31 and the busbar applying pressure roller 32 along the discharge direction of the busbar 20.

[0051] In this embodiment, the busbar straightening device 33 effectively eliminates any bending or twisting that may occur during the busbar 20's discharge process, ensuring it remains straight at all times. This avoids poor application caused by busbar 20 deformation, improving application accuracy and quality. After straightening, the busbar 20 can more accurately enter the busbar guide groove 34 and proceed along a predetermined path, ensuring precise contact with the insulating tape 10, further improving application consistency and reliability. By setting the busbar guide groove 34, the busbar 20 has a clear guiding path during transport, reducing jamming caused by positional deviation or entanglement, ensuring smooth operation of the entire application process. Simultaneously, it reduces the probability of equipment requiring maintenance due to frequent malfunctions, minimizing downtime and maintenance costs.

[0052] In some embodiments, the busbar feeding and applying mechanism 3 further includes a busbar cutting scissors 35, which is disposed between the busbar feeding tray 31 and the busbar applying pressure roller 32, and is close to the busbar applying pressure roller 32.

[0053] In this embodiment, the busbar cutting scissors 35 can cut the busbar 20. The busbar cutting scissors 35 can be used manually or automatically. By setting the busbar cutting scissors 35, precise length cutting can be performed after the busbar 20 is applied, ensuring that each section of the busbar 20 is of consistent length. This avoids poor application caused by inconsistent busbar 20 lengths, improving the consistency and aesthetics of the application. Simultaneously, the precise cutting by the busbar cutting scissors 35 maximizes the use of the busbar 20 material, reduces waste, and lowers production costs. The cut length of the busbar 20 is adapted to the actual needs of the insulating tape 10 and the battery assembly, avoiding problems caused by excessively long or short busbars 20 during application, such as folding, stacking, or insufficient length, ensuring a smooth application process.

[0054] Furthermore, in an embodiment with a busbar guide groove 34, a busbar cutting scissors 35 is disposed between the busbar guide groove 34 and the busbar application roller 32.

[0055] In some embodiments, the busbar feeding and applicating mechanism 3 further includes a busbar folding A-pressing fixture 36 and a busbar folding A-rod 37, which are adjustablely positioned on the movable seat 38 relative to the applicating platform 1. In the applicating displacement direction, the busbar folding A-pressing fixture 36 is positioned behind the busbar applicating pressure roller 32, and the busbar folding A-rod 37 is positioned between the busbar applicating pressure roller 32 and the busbar folding A-pressing fixture 36.

[0056] In this embodiment, by setting the busbar folding A-pressing fixture 36 and the busbar folding A-rod 37, the busbar 20 can be precisely folded A-shaped. The purpose of the folding A-shaped action is to leave an extra section of the busbar in the middle region along its length. This part of the busbar protrudes from the insulating tape and is used as the lead-out end of the electrode. That is, folding the busbar 20 A-shaped is to create the battery lead wire.

[0057] Among them, the busbar fold A pressing tool 36 and the busbar fold A rod 37 are respectively set to be raised or lowered or extended relative to the application platform 1. They can be driven manually or by a lifting mechanism or a telescopic mechanism.

[0058] In some embodiments, the insulating busbar picking mechanism 4 includes a horizontal rotation mechanism 41, a translation mechanism 42, and an insulating busbar picking robot 43. The insulating busbar picking robot 43 is disposed on the rotation end of the horizontal rotation mechanism 41, and the horizontal rotation mechanism 41 is disposed on the translation end of the translation mechanism 42.

[0059] In this embodiment, through the cooperation of the horizontal rotation mechanism 41 and the translation mechanism 42, the insulating busbar picking robot 43 can move precisely in multiple directions, ensuring that the position and posture of each picking operation meet the requirements. This improves the accuracy of picking and reduces picking failures caused by positional deviations. The horizontal rotation mechanism 41 can drive the insulating busbar picking robot 43 to rotate in the horizontal direction, allowing the robot to flexibly adjust its angle and switch between different workstations, ensuring the flexibility and wide applicability of the picking operation. The translation mechanism 42 can quickly move the insulating busbar picking robot 43 to the designated position, shortening the picking cycle. Combined with the rapid turning capability of the horizontal rotation mechanism 41, continuous and efficient operation is achieved, reducing downtime and improving production efficiency.

[0060] In some embodiments, the insulating busbar picking mechanism 4 further includes a second adsorption mechanism 44, which includes at least two negative pressure suction rods 441 arranged in parallel. One end of the negative pressure suction rod 441 is connected to the insulating busbar picking robot 43, and the other end of the negative pressure suction rod 441 is connected to a suction nozzle 442.

[0061] In this embodiment, the design of multiple negative pressure suction rods 441 and suction nozzles 442 allows for the simultaneous application of negative pressure adsorption force at different locations on the insulating busbar 30. This ensures the insulating busbar 30 is firmly adsorbed during material handling, achieving multi-point adsorption and reducing the risk of slippage or detachment due to unstable single-point adsorption. Furthermore, the multiple parallel negative pressure suction rods 441 can adsorb insulating busbars 30 of different specifications, expanding the applicability of the equipment. The negative pressure suction rods 441 can quickly establish and release negative pressure, achieving rapid adsorption and release, shortening the material handling cycle, and increasing the material handling speed.

[0062] Specifically, the diameter of the suction nozzle 442 is smaller than the width of the manifold 20.

[0063] In some embodiments, the insulating busbar picking mechanism 4 further includes an insulating tape separating cutter 45, which is located at one end of the insulating busbar picking robot 43 along the arrangement direction of the negative pressure suction rod 441.

[0064] In this embodiment, the insulating tape separating cutter 45 can precisely cut the insulating tape 10, cutting only the insulating tape 10 without breaking the release paper, ensuring that the position, length, and depth of each cut are consistent, thus improving the separation accuracy. Integrating the insulating tape separating cutter 45 onto the insulating busbar picking robot 43 achieves integrated picking and separating operations, reducing the changeover time between processes and improving overall work efficiency.

[0065] In some embodiments, a first driving device is further included, which is connected to the reel of the insulating tape release paper take-up tray 21 and is adapted to drive the insulating tape release paper take-up tray 21 to rotate; and / or, a second driving device is further included, which is connected to the reel of the busbar feed tray 31 and is adapted to drive the busbar feed tray 31 to rotate.

[0066] In this embodiment, the first driving device is connected to the reel of the insulating tape release paper take-up tray 21 and can drive the insulating tape release paper take-up tray 21 to rotate. Thus, the first driving device can drive the insulating tape release paper take-up tray 21 to rotate, realizing the automatic recycling of the insulating tape release paper. Simultaneously, when winding the insulating tape release paper, it can tighten the insulating tape 10.

[0067] The second drive unit is connected to the reel of the busbar feeding tray 31 and can drive the busbar feeding tray 31 to rotate. This enables automatic feeding of the busbar 20, reducing manual intervention and significantly improving the automation level of production. The first and second drive units can precisely control the rotation speed and angle of the reel, ensuring smooth and uniform unwinding and rewinding of the release paper and busbar 20, avoiding errors caused by manual operation or mechanical failure. Furthermore, precise drive control effectively reduces vibration and slack in the release paper and busbar 20 during transport, ensuring material quality and processing consistency.

[0068] Because of the busbar feeding tray 31 and the busbar application roller 32, the busbar 20 can be automatically discharged under the drive of the busbar application roller 32. When the second drive device is set, it can provide auxiliary power for the discharge of the busbar 20, ensure the smooth discharge of the busbar 20, and improve the application quality of the insulating busbar 30.

[0069] Specifically, in some embodiments, the first drive device and the second drive device are electric motors.

[0070] The main working process of the bonding device provided in this embodiment is as follows: First, the insulating tape 10 is adsorbed onto the surface of the bonding platform 1. Then, the busbar 20 is placed on the surface of the insulating tape 10 and folded (A-fold) is completed. The battery chip 40 flows into the bonding device. The insulating busbar picking robot 43 then places the folded insulating busbar 30 onto the surface of the corresponding position of the battery cell film layer. This enables the integrated placement of the insulating tape 10 and the busbar 20. No force is applied during the placement of the insulating busbar 30, and the entire process does not damage the film layer.

[0071] The specific workflow is as follows:

[0072] Insulating tape 10 loading: The worker loads and secures the insulating tape 10 onto the insulating tape loading tray 22, then pulls it along the application platform 1 to the insulating tape release paper receiving tray 21 for winding and securing. The release paper receiving tray 21 is then tightened to make the insulating tape 10 taut. The first adsorption mechanism 11 is then activated, and the insulating tape release paper and insulating tape 10 are firmly adsorbed onto the application platform 1. For loading a roll of insulating tape 10, only the initial section of the insulating tape 10 is cut off. Subsequent rolls of insulating tape 10 are simply transferred from the cut end to the beginning of the application platform 1 to complete the loading process.

[0073] The application process of manifold 20 is as follows Figure 6 As shown.

[0074] The operator fixes the disc-shaped busbar 20 onto the busbar feeding tray 31, pulls the busbar 20 through the busbar straightening device 33 and the busbar wire groove 34 to below the busbar application pressure roller 32, and cuts the busbar 20 with the busbar cutting scissors 35, removing the discarded busbar 20. After the insulating tape 10 is fed, the busbar feeding and application mechanism 3 moves to the head end of the application platform 1 via the moving module. The busbar wire groove 34 ejects the busbar 20 to below the busbar application pressure roller 32, and the busbar application pressure roller 32 presses down, fixing the head of the busbar 20 onto the insulating tape 10. The busbar feeding and application mechanism 3 slowly moves towards the insulating tape feeding tray 22, and the busbar 20 is firmly adhered to the surface of the insulating tape 10 under the action of the busbar application pressure roller 32. When the busbar feeding and application mechanism 3 moves to the middle of the insulating tape 10, it performs a folding action on the busbar 20. The specific process is as follows: Figure 7 As shown, the busbar feeding and application mechanism 3 operates in the direction indicated by the arrow. The busbar folding A-shaped pressing fixture 36 presses down on the busbar 20, ensuring that the applied busbar 20 and insulating tape 10 are not pulled off when the busbar application pressure roller 32 lifts them. The busbar application pressure roller 32 drives the busbar 20 to slowly lift backward and upward. The busbar folding A-shaped rod 37 presses down and extends below the busbar 20. After the busbar application pressure roller 32 is raised to a certain height, it presses down onto the surface of the insulating tape 10. The busbar folding A-shaped rod 37 lifts upward to complete the folding A-shape action and then compresses back down. The busbar folding rod 37 lifts the busbar folding pressing fixture 36. The busbar feeding and applying mechanism 3 slowly moves towards the tail end of the applying platform 1 while applying the busbar 20. When the busbar applying pressure roller 32 is within 5cm to 10cm of the tail end of the applying platform 1, the busbar cutting scissors 35 cuts the busbar 20. The busbar feeding and applying mechanism 3 continues to move towards the tail end of the applying platform 1 until the busbar applying pressure roller 32 completes the application of the cut and raised busbar 20.

[0075] For details on the folding action of the manifold 20 during the application process, please refer to the Chinese patent application document with publication number CN221466598U. This utility model only provides a brief introduction to this aspect.

[0076] Insulating busbar 30 adsorption and peeling: After the busbar 20 is applied to the insulating tape 10, the translation mechanism 42 drives the insulating busbar picking robot 43 to move downward. The suction nozzle 442 is close to the surface of the busbar 20, and the insulating tape separation cutter 45 extends to cut the insulating tape 10. At this time, the insulating tape release paper is not broken. The second adsorption mechanism 44 is activated. At the same time, the first adsorption mechanism 11 of the application platform 1 breaks the vacuum and cancels the adsorption. The second adsorption mechanism 44 of the insulating busbar picking robot 43 adsorbs the busbar 20 and the insulating tape 10 and slowly moves them towards the insulating tape release paper receiving tray 21. The first drive device operates synchronously to perform the insulating tape release paper receiving action until the insulating tape 10 and the insulating tape release paper are completely separated.

[0077] Insulating busbar 30 placement: The second adsorption mechanism 44 of the insulating busbar picking robot 43 adsorbs the insulating busbar 30. Simultaneously, the insulating busbar picking mechanism 4 moves downwards, driving the insulating tape separating cutter 45 to cut the insulating tape 10. After cutting, the insulating tape release paper does not break, only the insulating tape 10 breaks. The first driving device connected to the insulating tape release paper receiving tray 21 drives the insulating tape release paper receiving tray 21 to rotate, thereby transferring the cut edge of the insulating tape 10 to the head end of the application platform 1 (i.e., Figure 1 At the same time, the insulating busbar picking mechanism 4 moves synchronously with the insulating tape 10. During the winding process of the insulating tape release paper receiving tray 21, the insulating tape 10 is separated from the release paper until the cut insulating tape is completely separated from the release paper. The applied insulating busbar is completely adsorbed on the insulating busbar picking mechanism 4.

[0078] When the insulating busbar 30 is placed parallel to the long side of the battery chip, the insulating busbar picking robot 43 is transferred to the corresponding placement position of the battery chip 40 via the translation mechanism 42, breaking the vacuum and releasing the material. Figure 9 As shown. When the insulating busbar 30 is placed perpendicular to the long side of the battery chip, the insulating busbar picking robot 43 is translated to the middle position via the translation mechanism 42, and then rotated 90° via the rotation mechanism. The insulating busbar picking robot 43 is then translated to the corresponding placement position of the battery chip 40, breaking the vacuum and releasing the material, as shown. Figure 10 As shown. This ensures the precise placement of the insulating busbar 30, and the robotic arm's feeding position can be flexibly adjusted according to the laser cutting direction for different types of perovskite sub-cells, resulting in strong mechanism compatibility.

[0079] The placement of the insulating busbar 30 involves no force, unlike the complex actions of rolling, folding, and pulling on the film layer like a conventional film-applying roller. The film layer is minimally affected by the application, ensuring its integrity.

[0080] According to an embodiment of the present invention, in a second aspect, a photovoltaic cell production device is also provided, including the bonding device in the above embodiments, wherein the insulating busbar feeding mechanism 4 of the bonding device is adapted to place the insulating busbar 30 on the surface of the cell chip 40.

[0081] The photovoltaic cell production equipment provided in this embodiment includes the bonding device described in the previous embodiment. It pre-bonds the busbar 20 and insulating tape 10 to obtain an insulating busbar 30, and then places the insulating busbar 30 onto the cell chip 40. During this process, the surface of the cell chip 40 is not subjected to external force, eliminating the risk of film peeling, thereby improving the encapsulation quality of the perovskite module, enhancing product reliability, and increasing the overall module efficiency. Simultaneously, the cell chip 40 can achieve maximum area, eliminating the need for laser edge cleaning in the original busbar 20 area, thus improving module efficiency while maintaining product appearance. Furthermore, it features a simple structure, high automation, and convenient operation. It can be widely applied in various perovskite cell encapsulations, and the cutting of different products is convenient and quick.

[0082] Since photovoltaic cell production equipment includes a bonding device, it has all the effects of a bonding device, and other effects will not be elaborated here.

[0083] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
