Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module processing technology, and in particular relates to a trimming device for photovoltaic module processing. Background Technology

[0002] With the rapid development of the photovoltaic power generation industry, the requirements for the precision of photovoltaic module production process and appearance quality are constantly increasing. After the photovoltaic module is encapsulated and laminated, excess EVA film, backsheet material or glass roughness often remain on its edges. These edge defects not only affect the flatness of the module's appearance, but may also cause stress concentration during transportation or installation, thereby causing the module to crack or its waterproof performance to decline.

[0003] However, some problems still exist in the above solutions: Existing edge trimming methods mostly employ mechanical cutters or manual trimming. These methods suffer from uneven trimming, low precision, high labor intensity, and easy generation of debris. Furthermore, due to the brittle surface of photovoltaic panels, traditional edge trimming equipment, if subjected to excessive clamping force or inaccurate positioning, can easily cause glass chipping or backsheet scratches, severely impacting yield and module quality. Some existing processing equipment attempts to adopt automated edge trimming structures, but several shortcomings remain. On the one hand, traditional edge trimming mechanisms often rely on rigid clamping devices or fixed clamps, which, while simple in structure, lack buffer protection and are prone to causing localized damage to the photovoltaic module itself. On the other hand, during the edge trimming process, equipment vibration or airflow disturbances can cause slight displacement of the photovoltaic panel, resulting in non-parallel trimming lines or excessively deep cuts in certain areas, making it difficult to guarantee trimming quality. In addition, mechanical cutter trimming suffers from severe wear and excessive processing debris, increasing maintenance costs and affecting the cleanliness and safety of the photovoltaic modules. Utility Model Content

[0004] This invention provides a trimming device for processing photovoltaic modules, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a trimming device for processing photovoltaic modules includes: a processing table, a clamping and locking mechanism on the top of the processing table, and an anti-deviation mechanism in the middle of the processing table; The clamping and locking mechanism includes a connecting platform, spring rods, clamping plates, and buffer plates. The free ends of the two spring rods are fixedly connected to the clamping plates, and the inner sides of the two clamping plates are engaged with the buffer plates. The anti-deviation mechanism includes a suction cup, a connecting tube, and a transfer pump. One end of the connecting tube is fixedly connected to the suction cup, and one end of the suction cup is connected to the output end of the transfer pump.

[0006] Preferably, the top of the processing table is fixedly connected to two guide rails, and the top of the processing table is provided with two connecting platforms.

[0007] Preferably, the bottom end of one of the connecting platforms is slidably connected to the top ends of two guide rails, and a laser cutting machine is connected to the inner side of both connecting platforms.

[0008] Preferably, a support is fixedly connected to the top of one of the connecting platforms, and a motor is fixedly connected to the top of the other connecting platform. A lead screw is fixedly connected to the output end of the motor, and the middle part of the lead screw is threadedly connected to the middle part of the support.

[0009] Preferably, a photovoltaic module body is placed on the top of the processing table, and a support plate is fixedly connected to the inner side of each of the two connecting tables. The inner side of each of the two support plates is fixedly connected to the back of the two spring rods respectively.

[0010] Preferably, the inner sides of the two buffer plates are respectively attached to both sides of the photovoltaic module body.

[0011] Preferably, the processing table is provided with a connecting frame in the middle, the bottom end of the suction cup is fixedly connected to the top end of the connecting frame, and the bottom end of the connecting frame is fixedly connected to a mounting shell.

[0012] Preferably, the transfer pump is fixedly connected to the inner wall of the mounting housing, a connecting beam is fixedly connected to the outer side of the mounting housing, and the suction cup is attached to the bottom of the photovoltaic module body.

[0013] Compared with related technologies, the edge-trimming device for photovoltaic module processing provided by this utility model has the following beneficial effects: 1. In this utility model, the clamping and locking mechanism includes a connecting platform, spring rods, clamping plates, and buffer plates. When the photovoltaic module body is placed on the top of the processing table, the two spring rods drive the clamping plates to press inward, so that the buffer plates are attached and fixed to both sides of the photovoltaic module body. This effectively prevents the photovoltaic panel from shaking or shifting during the edge trimming process, and reduces the squeezing damage to the edges of the photovoltaic panel during clamping through the elasticity of the buffer plates. This improves the stability and safety of the processing. Through this structural design, the photovoltaic panel can be quickly positioned and reliably locked on the processing table, providing a stable support foundation for subsequent laser cutting. This avoids the problem of module breakage or scratches caused by excessive rigidity in traditional clamping methods, and significantly improves the practicality and processing accuracy of the edge trimming device.

[0014] 2. In this utility model, the anti-deviation mechanism works in coordination with the laser cutting machine. The anti-deviation mechanism consists of a suction cup, a connecting pipe, and a transmission pump. During the edge trimming operation, the transmission pump works to create negative pressure, and the suction cup tightly adheres to the bottom of the photovoltaic module body to achieve stable adsorption. This prevents the photovoltaic panel from shifting due to vibration or airflow during the laser cutting process, ensuring the accuracy of the cutting path. At the same time, laser cutting machines are installed on the inner sides of the two connecting platforms. Driven by the motor and lead screw, they can achieve smooth reciprocating motion along the guide rail, thereby simultaneously trimming both sides of the photovoltaic module body. This structure not only improves processing efficiency but also avoids the problems of traditional tool wear and chip contamination by using non-contact laser cutting, making the trimmed surface smoother and neater, effectively improving the appearance quality and product consistency of the photovoltaic module.

[0020] In a further preferred embodiment of the present invention, two guide rails 6 are fixedly connected to the top of the processing table 1, and two connecting platforms 203 are provided on the top of the processing table 1.

[0021] In this embodiment, two guide rails 6 are arranged parallel to each other along the length of the processing table 1 to guide the smooth movement of the connecting table 203 and ensure the motion accuracy of the laser cutting machine 4 during the edge trimming process. The guide rails 6 are made of wear-resistant stainless steel, which has good stability and durability and can adapt to long-term continuous processing use, ensuring that the edge trimming device operates smoothly and reliably, and improving the overall processing efficiency and cutting consistency.

[0022] In a further preferred embodiment of the present invention, the bottom end of one of the connecting platforms 203 is slidably connected to the top end of the two guide rails 6, and the inner sides of the two connecting platforms 203 are connected to laser cutting machines 4.

[0023] In this embodiment, the laser cutting machine 4 can move along the edge of the photovoltaic module body 3 on the guide rail 6 to perform edge trimming. By precisely controlling the cutting path and speed, a high-precision cutting effect is achieved. The sliding connection structure reduces frictional resistance, making the laser cutting machine 4 run smoothly and steadily, reducing processing deviations, improving the surface quality of the trimmed edge and the service life of the equipment.

[0024] In a further preferred embodiment of the present invention, a support 208 is fixedly connected to the top of one of the connecting platforms 203, and a motor 204 is fixedly connected to the top of the other connecting platform 203. A lead screw 201 is fixedly connected to the output end of the motor 204, and the middle part of the lead screw 201 is threadedly connected to the middle part of the support 208.

[0025] In this embodiment, the linear movement of the connecting table 203 can be achieved by the motor 204 driving the lead screw 201 to rotate, thereby driving the laser cutting machine 4 to move synchronously along the guide rail 6. The lead screw 201 transmission structure is stable and reliable, with high positioning accuracy and repeatability, ensuring a smooth and vibration-free edge trimming process.

[0026] In a further preferred embodiment of the present invention, a photovoltaic module body 3 is placed on the top of the processing table 1, and a support plate 202 is fixedly connected to the inner side of each of the two connecting tables 203. The inner side of each of the two support plates 202 is fixedly connected to the back of each of the two spring rods 205.

[0027] In this embodiment, the reset spring rod 205 can automatically push the support plate 202 back to the initial position after the edge trimming is completed, which facilitates the reset and repositioning of the clamping device, ensuring that the photovoltaic module body 3 is picked up and placed more conveniently and efficiently, reducing manual operation steps, and improving the overall automation level and production efficiency.

[0028] In a further preferred embodiment of this utility model, the inner sides of the two buffer plates 206 are respectively attached to both sides of the photovoltaic module body 3.

[0029] In this embodiment, the buffer plate 206 is made of highly elastic rubber material, which can play a protective and buffering role when clamping the photovoltaic panel, avoiding damage or cracking of the photovoltaic panel edge due to excessive clamping force, while improving the fixing stability, keeping the photovoltaic panel flat during the edge trimming process, ensuring the consistency of the laser cutting path, thereby effectively improving the edge trimming accuracy and product quality. Example

[0030] Based on Embodiment 1, a preferred embodiment of the edge-trimming device for photovoltaic module processing provided by this utility model is as follows: Figures 5 to 6 As shown: A connecting frame 502 is provided in the middle of the processing table 1. The bottom end of the suction cup 501 is fixedly connected to the top end of the connecting frame 502. A mounting shell 504 is fixedly connected to the bottom end of the connecting frame 502.

[0031] In this embodiment, the connecting frame 502 is made of high-strength metal material to support the overall structure of the suction cup 501 and the mounting shell 504, making the anti-deviation mechanism 5 more stable and reliable. The suction cup 501 generates negative pressure adsorption force under the action of the transfer pump 505, which effectively prevents the photovoltaic panel from moving during the edge trimming process and ensures that the edge trimming lines are straight and have high precision.

[0032] In a further preferred embodiment of the present invention, the transfer pump 505 is fixedly connected to the inner wall of the mounting shell 504, the outer side of the mounting shell 504 is fixedly connected to the connecting beam 506, and the suction cup 501 is attached to the bottom of the photovoltaic module body 3.

[0033] In this embodiment, the suction cup 501 is attached to the bottom of the photovoltaic module body 3. The transfer pump 505 is connected to the suction cup 501 through the connecting pipe 503 to form a vacuum adsorption, which can continuously provide a stable adsorption force during the photovoltaic panel processing, preventing the photovoltaic panel from shifting due to vibration or external force. The connecting beam 506 structure enhances the overall rigidity, improves the vibration resistance of the equipment, and makes the edge trimming operation more stable and reliable.

[0034] In summary, during operation, the photovoltaic module body 3 is first placed on the top surface of the processing table 1. Two guide rails 6 are provided on both sides of the top of the processing table 1. The bottom end of one of the connecting platforms 203 can slide along the guide rail 6, thereby realizing the precise movement of the laser cutting machine 4 in different directions. The laser cutting machine 4 is installed on the inner side of the two connecting platforms 203 respectively, forming a double-sided collaborative edge cutting structure, which can simultaneously cut both sides of the photovoltaic module body 3. When the equipment is started, the motor 204 starts to work. Its output end is fixedly connected to the lead screw 201. The middle part of the lead screw 201 is threadedly connected to the middle part of the support 208. The motor 204 drives the lead screw 201 to rotate, so that the connecting table 203 can move smoothly along the guide rail 6. This mechanism can drive the laser cutting machine 4 to reciprocate in the horizontal direction, so that its cutting path is evenly distributed on the edge of the photovoltaic module body 3, achieving precise edge trimming. The transmission structure of the lead screw 201 makes the movement more stable, effectively avoids the vibration generated during the cutting process, and improves the edge trimming accuracy and the neatness of the photovoltaic panel edge. During the placement of the photovoltaic module body 3, the clamping and locking mechanism 2 plays a crucial role in fixing it. The clamping and locking mechanism 2 includes a connecting platform 203, spring rods 205, clamping plates 207, and buffer plates 206. The free ends of the two spring rods 205 are respectively fixedly connected to the clamping plates 207. The inner side of the clamping plates 207 is provided with buffer plates 206, which are used to fit against the two sides of the photovoltaic module body 3. When the clamping mechanism clamps inward, the spring rods 205 provide elastic force, so that the clamping plates 207 firmly press against the two sides of the photovoltaic module body 3. The elastic fit of the buffer plates 206 can play a buffering and protective role, preventing damage to the module glass layer or back sheet caused by rigid clamping, thereby ensuring processing safety and positioning accuracy. To prevent the photovoltaic panel from shifting due to vibration or airflow disturbance during the edge trimming process, an anti-offset mechanism 5 is provided in the middle of the device. The anti-offset mechanism 5 includes a suction cup 501, a connecting pipe 503, and a transfer pump 505. The suction cup 501 is connected to the output end of the transfer pump 505 through the connecting pipe 503. When the transfer pump 505 is working, a negative pressure is formed in the suction cup 501, thereby firmly adsorbing the photovoltaic module body 3 onto the surface of the processing table 1, which plays a role in anti-slip and anti-offset. The bottom end of the suction cup 501 is fixedly connected to the top end of the connecting frame 502. The bottom end of the connecting frame 502 is fixedly connected to the mounting shell 504. The transfer pump 505 is installed inside the mounting shell 504, and the connecting beam 506 is fixedly connected to the outside, making the entire anti-offset system structure stable and compact. During the edge trimming process, two laser cutting machines 4 are started simultaneously according to the set program. The laser beam moves along the edge area of ​​the photovoltaic module body 3. The high-energy laser beam is focused on the edge, instantly vaporizing or melting the excess EVA film, backsheet or glass burrs, thereby achieving smooth non-contact edge trimming. Compared with the traditional mechanical edge trimming method, the laser cutting machine 4 has high processing precision, neat edges and no debris, which can effectively avoid the problem of module edge cracking. After the edge trimming operation is completed, the motor 204 rotates in reverse, and the lead screw 201 drives the connecting table 203 to reset. At the same time, the two support plates 202 automatically return to their initial positions under the elastic action of the spring rod 205, so that the clamping plate 207 gradually releases the photovoltaic module body 3. After the transfer pump 505 stops working, the suction cup 501 releases its adsorption, and the photovoltaic panel can be safely removed, completing one edge trimming cycle.
