Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel processing technology, specifically to a laser cutting device for photovoltaic panels used in photovoltaic power generation and heating systems. Background Technology

[0002] Photovoltaic power generation and heating systems utilize solar photovoltaic panels to generate electricity to drive heating equipment, achieving the technical purpose of clean heating and hot water supply. Among them, photovoltaic panels are the most important components in photovoltaic power generation and heating systems, directly determining the efficiency and stability of the entire heating system. In the production and manufacturing process of photovoltaic panels, standard-sized photovoltaic cells are generally produced first, and then they are cut into strips or rectangles according to design requirements using laser cutting. The photovoltaic cells are then arranged and welded, and finally laminated and encapsulated into a complete photovoltaic panel.

[0003] Currently, in the laser cutting production process of photovoltaic cells in photovoltaic panel manufacturing, the operator first places the workpiece to be cut flat on the processing platform of the existing dicing machine. The edge of the cell is captured and positioned by a vision positioning system (such as CCD camera shooting for positioning). Then, a laser beam is emitted to move and cut along a set trajectory, eventually forming many small cell pieces, thus completing the laser cutting operation.

[0004] The following problems exist in the existing laser cutting process: Although the workpiece is positioned by a vision positioning system, it is not restricted or locked during the cutting process. As a result, the stress release caused by the solar cell detaching from the workpiece during cutting causes the workpiece to slide, rotate, or warp at the edges to a certain extent. This affects the subsequent cutting reference of the solar cell, which can lead to over-cutting of the solar cell by the laser, resulting in damage to the solar cell and rendering it unusable. Summary of the Invention

[0005] Therefore, it is necessary to provide a photovoltaic panel laser cutting device for photovoltaic power generation and heating systems, which aims to solve the problems of the above-mentioned prior art.

[0006] This application provides a photovoltaic panel laser cutting device for a photovoltaic power generation and heating system, comprising: a working chamber, a laser cutting assembly disposed on the rear side of the working chamber, the laser cutting assembly including a laser emitter, a fixed frame fixedly disposed in the working chamber below the laser emitter, and a fence frame for supporting the workpiece fixedly disposed in the fixed frame.

[0007] The work chamber is equipped with a positioning component, which positions and locks the workpiece so that the center of each battery cell is located within the gap of the fence frame.

[0008] The work chamber is equipped with a mobile platform located below the fence frame. Above the mobile platform, four rectangular suction devices are arranged via two left and right movable plates. The mobile platform is equipped with an adjustment component for adjusting the position of the suction devices.

[0009] The adsorption component is provided with a protective component, which forms a protective area whose edge extends beyond the edge of the battery cell by a specified length.

[0010] While locking the workpiece with the positioning component, the center of the battery cell is positioned in the middle of the gap between the grid frame. The position of the adsorption component is adjusted by the adjustment component, and the adsorption component is moved sequentially to the bottom of each battery cell by the moving platform. During laser cutting, the bottom side of the battery cell is adsorbed and locked, and the bottom edge is protected by the protection component.

[0011] According to an advantageous embodiment, an L-shaped fixing member is provided on the left rear side of the work compartment, located above the fence frame, with the inside corner of the fixing member facing the workpiece.

[0012] T-shaped frames are slidably installed on the front and right sides of the work chamber, and each T-shaped frame is equipped with a bonding roller with a vertical axis that fits the edge of the workpiece.

[0013] According to an advantageous embodiment, a lower pressure ring is fixedly sleeved on the bonding roller, and a lower pressure plate is fixedly disposed in the inner corner area of ​​the fixing member.

[0014] According to an advantageous embodiment, the fastener is detachably installed, and when the left rear corner of the workpiece abuts against the inner wall of the inner corner area of ​​the fastener, the middle position of the battery cell in the left-right direction is located within the gap of the fence frame.

[0015] According to an advantageous embodiment, the right-side movable plate is slidably mounted above the movable platform via four rectangularly arranged lifting rods with vertical axes, while the left-side movable plate is slidably mounted on the right-side movable plate and the movable platform.

[0016] The movable plate has two sliding blocks arranged in a front-to-back manner, with pipes running through the sliding blocks, and the adsorption component is fixedly installed above the pipes.

[0017] According to an advantageous embodiment, the movable plate is rotatably permeated by a bidirectional threaded rod whose axis extends from front to back, and the bidirectional threaded rod is threaded through two sliding blocks on the same side.

[0018] According to an advantageous embodiment, limiting plates are fixedly provided on both the front and rear sides of the upper surface of the movable plate. When the movable plate drives the limiting plates to move up and contact the lower surface of the fence frame, the adsorption member moves and fits against the lower surface of the battery cell.

[0019] According to an advantageous embodiment, the protective assembly includes two replacement plates distributed front to back, which are then assembled above the sliding block and sleeved on the pipe after being attached front to back.

[0020] The edge area formed by the two replacement plates is larger than the edge area of ​​the corresponding battery cell, and a laser receiving plate adapted to the edge direction is fixedly installed on the upper edge of the replacement plate.

[0021] According to an advantageous embodiment, two left-right distributed docking posts with their axes extending from front to back are fixedly provided on the front end face of the rear replacement plate on the same pipe, and a docking groove corresponding to the docking post is opened on the rear end face of the corresponding front replacement plate.

[0022] The upper surface of the sliding block has four rectangular slots with vertical axes, and the lower surface of the replacement plate is fixedly provided with a corresponding snap-fit ​​post.

[0023] In summary, the present invention has the following beneficial effects: The present invention uses a positioning component in conjunction with a CCD camera to form a dual positioning system combining mechanical and visual positioning. Mechanical positioning improves stability during cutting, reduces workpiece edge deformation caused by stress changes, and provides a reference guide for subsequent adsorption actions. Secondly, the adsorption process of the adsorption component reduces the impact of stress release during the separation of the battery cells, improving stability and cutting accuracy. Simultaneously, a protective component forms a rectangular area to protect the battery cells, preventing over-cutting and damage. In conclusion, by strengthening the positioning reference, reducing stress through adsorption, and protecting the reference, the present invention ensures precise cutting of the battery cells.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2 As shown, a photovoltaic panel laser cutting device for a photovoltaic power generation and heating system includes: a working chamber 1, a laser cutting component 2 is arranged on the rear side of the working chamber 1, the laser cutting component 2 includes a laser emitter 20 that can move adaptively, a fixed frame 3 located below the laser emitter 20 is fixedly arranged in the working chamber 1, and a fence frame 4 for supporting the workpiece is fixedly arranged in the fixed frame 3.

[0036] The work chamber 1 is equipped with a positioning component 5, which positions and locks the workpiece so that the center of each battery cell is located in the gap of the fence frame 4. The positioning component 5 also includes an external existing CCD camera (not shown in the figure) set above the fence frame 4.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, the working chamber 1 is equipped with a mobile platform 6 located below the fence frame 4. Above the mobile platform 6, four rectangular adsorption components 7 are arranged through two left and right distributed mobile plates 63. The adsorption components 7 are connected to an external air pump (not shown in the figure). The mobile platform 6 is equipped with an adjustment component 8 for adjusting the position of the adsorption components 7.

[0038] like Figure 5 and Figure 6 As shown, the adsorption component 7 is provided with a protective component 9, which forms a protective area whose edge extends beyond the edge of the battery cell by a specified length.

[0039] During operation, the operator places the photovoltaic cells to be cut (collectively referred to as workpieces) onto the grid frame 4, and uses the positioning component 5 to clamp and lock the workpiece in both the circumferential and vertical positions, ensuring that the center of each cell in the workpiece is within the gap of the grid frame 4. This ensures that the subsequent adsorption action can be performed. After the mechanical locking and positioning is completed, the surface features of the workpiece are photographed by a CCD camera, and the collected data is transmitted to the existing information processing terminal. The center position of each cell is determined through feedback information.

[0040] It should be noted that both the mobile platform 6 and the laser cutting component 2 are capable of moving in the forward and backward and left and right directions, and the movement process is controlled by an information processing terminal. The mobile platform 6 is controlled to move adaptively according to the center position of the battery cell. The above-mentioned processing process and information processing terminal are all external existing technologies, which are not shown and will not be described in detail later.

[0041] After the workpiece and battery cells are positioned, the positions of the four adsorption components 7 are adjusted by the adjustment component 8. Then, the moving platform 6 moves the adsorption components 7 to below the four battery cells. At this time, the adsorption components 7 are directly below the corresponding battery cells. The adsorption components 7 move up and adsorb the corresponding battery cells. Then, the laser cutting component 2 adaptively moves to the corresponding position and emits a laser through the laser emitter 20 to cut the edges of the battery cells one by one. By adsorbing the adjacent battery cells at the cutting position by the adsorption components 7, the problem of the position of the adjacent remaining battery cells being affected by the stress caused by the battery cells detaching during cutting is reduced. The above process is repeated to complete the laser cutting of all battery cells on the workpiece.

[0042] Secondly, during each cutting operation, an alternative protective area is formed directly below the solar cell by the protective component 9. When the laser touches the protective area, the cutting stops to avoid over-cutting and damage to the solar cell.

[0043] like Figure 2 and Figure 4 As shown, an L-shaped fixing member 50 is provided on the left rear side of the work chamber 1, located above the fence frame 4, with the inside corner of the fixing member 50 facing the workpiece.

[0044] like Figure 2 and Figure 3 As shown, T-shaped frames 51 are slidably arranged on the front and right sides of the work chamber 1. The T-shaped frames 51 are all driven to move by external electric guide rods (not shown in the figure). Each T-shaped frame 51 is rotatably equipped with a bonding roller 52 with a vertical axis that fits the edge of the workpiece.

[0045] like Figure 3 and Figure 4 As shown, a lower pressure ring 53 is fixedly sleeved on the bonding roller 52, and a lower pressure plate 54 is fixedly installed in the inner corner area of ​​the fixing member 50. In order to facilitate the lower pressure ring 53 to press the edge of the workpiece, the lower edge of the lower pressure ring 53 is chamfered.

[0046] like Figure 2 and Figure 4 As shown, the fastener 50 is detachably installed. When the top corner of the left rear side of the workpiece is pressed against the inner wall of the inner corner area of ​​the fastener 50, the middle position of the battery cell in the left-right direction is located in the gap of the fence frame 4.

[0047] During operation, the workpiece is first placed flat on the fence frame 4 by hand. The workpiece is moved according to its size and the fixing part 50 is installed in the set position to ensure that the workpiece is above the fence. The workpiece is moved manually so that the top corner of the left rear side of the workpiece is inserted into the inside corner area of ​​the fixing part 50, and the fixing part 50 is inserted into the bottom of the lower pressure plate 54.

[0048] Then, the external electric guide rod operates, causing the T-shaped frame 51 to move closer to the workpiece synchronously. The T-shaped frame 51 drives the bonding roller 52 on it to finally contact the workpiece. Finally, the bonding roller 52 and the fixing member 50 work together to fix the workpiece at a fixed angle, thus completing the circumferential positioning of the workpiece. This ensures that the length direction of the battery cell is the same as the length direction of the fence frame 4, and the center position of the battery cell is located in the gap area of ​​the fence frame 4. Secondly, during the bonding process of the bonding roller 52, the bonding roller 52 drives the pressing collar 53 on it to press the edge of the workpiece. Therefore, through the pressing action of the pressing collar 53 and the pressing plate 54, the workpiece is pressed and clamped in the periphery of the workpiece, improving the stability during cutting and reducing the problem of workpiece edge deformation caused by stress changes and affecting cutting stability.

[0049] like Figure 5 and Figure 6 As shown, the right-side movable plate 63 is slidably mounted above the movable platform 6 via four rectangularly arranged and vertically aligned lifting rods 60. The right-side movable plate 63 is driven to rise and fall by an external hydraulic cylinder (not shown in the figure). The left-side movable plate 63 is slidably mounted on the right-side movable plate 63 and the movable platform 6.

[0050] like Figure 7 As shown, two sliding blocks 61 are slidably arranged on the moving plate 63, and a pipe 62 is provided through the sliding block 61. The adsorption element 7 is fixedly arranged above the pipe 62, so that the adsorption element 7 is connected to an external air pump (not shown in the figure) through the pipe 62.

[0051] like Figure 5 and Figure 7 As shown, an external electric push rod (not shown in the figure) is provided between the two movable plates 63. A bidirectional threaded rod 80 with its axis extending from front to back is rotatably passed through the movable plate 63. The bidirectional threaded rod 80 is threaded through two sliding blocks 61 on the same side. The bidirectional threaded rod 80 is connected to an external motor (not shown in the figure).

[0052] like Figure 5 and Figure 6 As shown, limiting plates 81 are fixedly installed on both the front and rear sides of the upper surface of the movable plate 63. When the movable plate 63 moves the limiting plates 81 upward to contact the lower surface of the fence frame 4, the adsorption member 7 moves and fits against the lower surface of the battery cell without exerting an upward force on the battery cell.

[0053] Before cutting, the spacing between two adjacent adsorption components 7 is adjusted according to the spacing between two adjacent battery cells. The specific steps are as follows: The external electric push rod operates to move the left moving plate 63 synchronously with the adsorption components 7 on it, adjusting the spacing between the left and right adjacent adsorption components 7 to be the same as the spacing between the left and right adjacent battery cells. The external motor operates to rotate the bidirectional threaded rod 80. Through the cooperation between the bidirectional threaded rod 80 and the corresponding sliding block 61, the sliding block 61 moves. Therefore, the spacing between the front and rear adjacent adsorption components 7 is adjusted to be the same as the spacing between the front and rear adjacent battery cells. It should be noted that the above process is adapted based on the size and specifications of the battery cells in the corresponding workpiece. All of these are results obtained by those skilled in the art through multiple tests, meeting the requirements of subsequent processing operations. Further details will not be elaborated upon hereafter.

[0054] After the workpiece is clamped and positioned, the moving platform 6 moves the moving plate 63 and the suction component 7 on it synchronously to the set position. At this time, the suction component 7 is located directly below the center of the corresponding battery cell. Then, the external hydraulic cylinder works to make the two moving plates 63 move upward synchronously. The suction component 7 gradually enters the gap of the fence frame 4 from below. In the above process, the moving plate 63 moves the limiting plate 81 on it synchronously upward. When the limiting plate 81 contacts the lower end of the fence frame 4, the suction component 7 moves upward to contact the lower end face of the battery cell. Through the cooperation between the limiting plate 81 and the fence frame 4, the upward movement distance of the suction component 7 is limited, ensuring that the suction component 7 can contact the battery cell without exerting an upward force on the battery cell. This avoids the problem of the suction component 7 pushing the battery cell upward during its upward movement contradicting the downward pressing action of the positioning component 5, which could cause damage to the battery cell.

[0055] An external air pump applies an adsorption force to the battery cells through pipe 62 and adsorption element 7. Therefore, regardless of whether the battery cells have been cut, they are adsorbed onto the corresponding adsorption element 7. This ensures cutting stability and accuracy when the four adsorbed battery cells are cut. Furthermore, when adjacent battery cells are separated from the workpiece after cutting, the adsorption action reduces the stress generated during the separation process.

[0056] After the battery cell cutting operation on the adsorption component 7 is completed, the external air pump works to release the adsorption component 7 from the battery cell, the moving plate 63 moves down to reset, and the moving platform 6 drives the moving plate 63 to the next position and repeats the above operation process.

[0057] like Figure 5 , Figure 6 and Figure 7 As shown, the protective component 9 includes two replacement plates 90 distributed front to back. The two replacement plates 90 are attached front to back and assembled above the sliding block 61 and sleeved on the pipe 62.

[0058] The edge area formed by the two replacement plates 90 is larger than the edge area of ​​the corresponding battery cell, and a laser receiving plate 91 adapted to the edge direction is fixedly provided on the upper edge of the replacement plate 90.

[0059] like Figure 7 and Figure 8 As shown, two docking posts 92, which are distributed left and right and whose axes extend from front to back, are fixedly provided on the front end face of the rear replacement plate 90 on the same pipe 62. A docking groove 93 corresponding to the docking post 92 is opened on the rear end face of the front replacement plate 90.

[0060] The upper end face of the sliding block 61 is provided with four rectangular slots 94 arranged with vertical axes, and the lower end face of the replacement plate 90 is fixedly provided with a slot post 95 corresponding to the slot 94.

[0061] Before cutting, a suitable replacement plate 90 is selected according to the size and specifications of the battery cell. The two replacement plates 90 are initially assembled by the cooperation between the mating posts 92 and the mating grooves 93 on the two plates. At this time, the two replacement plates 90 are closed and fitted onto the pipe 62 and located directly above the corresponding sliding block 61. Then, the replacement plates 90 are manually lowered so that the snap-fit ​​posts 95 on the replacement plates 90 are snapped into the corresponding snap-fit ​​grooves 94, completing the assembly process of the replacement plates 90. At this time, the two replacement plates 90 are installed on the corresponding sliding block 61 in a closed state. The rectangular area formed by the two replacement plates 90 is larger than the rectangular area of ​​the battery cell directly above, and the center of the rectangular area formed is vertically aligned with the center of the battery cell.

[0062] Therefore, during the subsequent laser cutting process, the laser movement is limited by the edge of the laser receiving plate 91 on the replacement plate 90. That is, when the laser cuts excessively and the laser comes into contact with the laser receiving plate 91, it means that if the laser continues to move, it will cut the battery cell body and damage the battery cell. Therefore, after receiving the laser, the laser receiving plate 91 converts the received information into an electrical signal and transmits it to the information processing terminal to control the laser cutting action to stop. In summary, the rectangular area formed by the replacement plate 90 protects the battery cell and avoids the problem of damage to the battery cell due to excessive cutting. Secondly, different sizes of replacement plates 90 are selected according to the different sizes of battery cells, which improves the adaptability and flexibility of the device. Moreover, it can be used for a long time after a single installation, reducing the actual cost required to achieve the desired effect.

[0063] It should be further explained that in existing technologies, the workpiece is placed and positioned visually before laser cutting. This technical solution adds a positioning component 5, an adsorption component 7, and a protective component 9. The positioning component 5 employs a dual positioning system combining mechanical positioning and CCD camera visual positioning, ensuring not only the accuracy of the battery cell positioning but also pressing down to clamp the workpiece, improving stability during cutting, reducing workpiece edge deformation caused by stress changes, and providing a reference guide for subsequent adsorption actions. The adsorption component 7 reduces the stress generated during the battery cell separation process through adsorption, improving stability and cutting accuracy. The protective component 9 forms a rectangular area to protect the battery cell, preventing over-cutting and damage. All the added components are existing conventional mechanical parts, usable long-term after a single installation. Therefore, compared to the economic benefits of improving laser cutting stability and accuracy, the cost of these additional components is negligible. In summary, this technical solution is a specific improvement based entirely on and addressing the shortcomings of existing technologies.
