Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a photovoltaic module welding flatness testing device. Background Technology

[0002] The weld flatness of photovoltaic modules refers to the degree of unevenness on the surface of the welded part, which reflects the quality and precision of the welding process.

[0003] The flatness of the weld directly affects the sealing, durability, and power generation efficiency of photovoltaic modules. Uneven welds can allow moisture, dust, and other impurities to enter the module, impacting its performance and lifespan. Therefore, after welding, the flatness of the weld joints needs to be checked to prepare for subsequent adjustments. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the problem in the prior art that it is necessary to detect the flatness of the weld joint of photovoltaic modules in order to prepare for subsequent repairs, a photovoltaic module weld flatness detection device is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a photovoltaic module welding flatness detection device, including a support, a transmission mechanism, a detection mechanism and a lifting mechanism. The transmission mechanism and the support are fixedly connected. The transmission mechanism is used to transport the photovoltaic module and make the photovoltaic module pass through the detection mechanism. The lifting mechanism and the support are fixedly connected. The output end of the lifting mechanism is fixedly connected to the detection mechanism. The lifting mechanism is used to provide power for the detection mechanism to move away from or closer to the photovoltaic module. The detection mechanism is used to detect whether the thickness of the weld of the photovoltaic module is within the qualified range.

[0006] The testing mechanism includes a fixed plate, a testing plate, a fixed contact, a moving contact, an elastic element, and a connecting rod. The fixed plate is fixedly connected to the output end of the lifting mechanism. The lower end of the connecting rod is provided with a threaded section, which is threadedly connected to the testing plate. The upper end of the connecting rod is slidably connected to the fixed plate. The elastic element is sleeved on the connecting rod and is located between the fixed plate and the testing plate. The elastic element is used to maintain the distance between the moving contact and the fixed contact. The fixed contact is fixedly connected to the bottom surface of the fixed plate, and the top surface of the testing plate is fixedly connected to the moving contact. Through the design of the testing components, it is possible to quickly detect whether the thickness of the weld meets the standard, thus avoiding its impact on subsequent installation. Furthermore, through the design of the printing roller, welds exceeding the qualified thickness can be marked for easy subsequent identification and processing, improving processing efficiency.

[0007] When the fixed contact and the moving contact come into contact, it can send a signal that the thickness of the weld exceeds the acceptable range.

[0008] To address the issue of how to arrange the lifting mechanism, the lifting mechanism further includes a cylinder, with the cylinder and bracket fixedly connected, and the piston rod of the cylinder and a fixed plate fixedly connected.

[0009] To address the issue of low stability during cylinder movement, a lifting mechanism is further included, comprising a guide seat. The guide seat has a through hole for the piston rod of the cylinder to pass through, and the piston rod of the cylinder is located within the through hole of the guide seat.

[0010] To address the issue of photovoltaic modules being difficult to enter between the testing board and the transmission mechanism, a further improvement is made by providing a rounded chamfer at the lower end of the testing board facing the transport direction of the transmission mechanism.

[0011] To address the issue of the elastic element affecting the user's ability to apply force and rotate the connecting rod between the fixed plate and the detection plate, a further improvement is made by arranging a support plate on the connecting rod. The support plate is located between the fixed plate and the detection plate, above the threaded section of the connecting rod, with one end of the elastic element abutting against the fixed plate and the other end abutting against the support plate.

[0012] To address the issue of preventing the connecting rod from detaching from the fixed plate, a limiting block is further included on the top of the connecting rod, with the limiting block positioned above the fixed plate.

[0013] To address the inconvenience of locating substandard welds during subsequent grinding, a further feature includes a receiving groove on the bottom surface of the inspection plate, within which is arranged a printing roller for applying marks to welds that exceed specifications. The printing roller and the inspection plate are rotatably connected.

[0014] To address the issue of insufficient coating material, the method further includes arranging ink paste in the receiving tank, with the ink paste positioned above the printing roller and in contact with the printing roller.

[0015] Furthermore, rollers are installed on the bottom surface of the detection plate.

[0016] The beneficial effects of this utility model are: the photovoltaic module welding flatness detection device provided by this utility model can quickly detect whether the thickness of the weld meets the standard through the design of the detection component, so as to avoid affecting the subsequent installation. In addition, through the design of the printing roller, the weld exceeding the qualified thickness can be marked, which facilitates subsequent identification and processing and improves processing efficiency.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figure 1 This is a schematic diagram of the structure of this utility model, a photovoltaic module welding flatness detection device, including a support 1, a transmission mechanism 2, a detection mechanism 3, and a lifting mechanism 4. The transmission mechanism 2 is fixedly connected to the support 1. The transmission mechanism 2 is used to transport the photovoltaic module and allow the photovoltaic module to pass through the detection mechanism 3. The transmission mechanism 2 can be a chain plate conveyor or a translational transmission device (e.g., a placement platform pushed by a cylinder). The lifting mechanism 4 is fixedly connected to the support 1. The output end of the lifting mechanism 4 is fixedly connected to the detection mechanism 3. The lifting mechanism 4 is used to provide power for the detection mechanism 3 to move away from or closer to the photovoltaic module. The lifting mechanism 4 includes a cylinder 41. The cylinder 41 is fixedly connected to the support 1. The piston rod of the cylinder 41 is fixedly connected to the fixed plate 31. The size of the photovoltaic module to be detected is adjusted by the cylinder 41. The cylinder 41 can also be replaced by a lead screw mechanism or an electric push rod, etc.

[0025] The lifting mechanism 4 includes a guide seat 42, which has a through hole for the piston rod of the cylinder 41 to pass through. The piston rod of the cylinder 41 is located in the through hole of the guide seat 42, and the guide seat 42 increases the stability of the cylinder 41 drive.

[0026] like Figure 2 , Figure 3As shown, the testing mechanism 3 is used to test whether the thickness of the weld joint of the photovoltaic module is within the acceptable range. The testing mechanism 3 includes a fixed plate 31, a testing plate 32, a fixed contact 33, a moving contact 34, an elastic element 35, and a connecting rod 36. The fixed plate 31 is fixedly connected to the output end of the lifting mechanism 4. A threaded section 361 is provided on the lower end of the connecting rod 36. The threaded section 361 of the connecting rod 36 is threadedly connected to the testing plate 32. The upper end of the connecting rod 36 is slidably connected to the fixed plate 31. The elastic element 35 is sleeved on the connecting rod 36, and the elastic element 35 is located between the fixed plate 31 and the testing plate 32. Between the plates 32, the elastic element 35 is used to maintain the distance between the moving contact 34 and the fixed contact 33. The fixed contact 33 is fixedly connected to the bottom surface of the fixed plate 31, and the top surface of the detection plate 32 is fixedly connected to the moving contact 34. The elastic element 35 can be a steel ring spring, rubber spring, or other elastic element. The elastic element 35 is used to maintain the distance between the detection plate 32 and the fixed plate 31, that is, to maintain the distance between the fixed contact 33 and the moving contact 34. Since the thickness difference range at the weld is small, the distance between the fixed contact 33 and the moving contact 34 is short. Therefore, it avoids the two from generating false contact signals due to vibration contact.

[0027] When the fixed contact 33 and the moving contact 34 come into contact, they can send a signal that the thickness of the weld exceeds the acceptable range, which can quickly detect whether the thickness of the weld meets the standard and avoid affecting subsequent installation.

[0028] Cylinder 41 provides coarse adjustment for detecting the thickness of the photovoltaic module and weld joint, while threaded section 361 on connecting rod 36 provides fine adjustment for detecting the thickness of the photovoltaic module and weld joint.

[0029] like Figure 2 , Figure 3 As shown, the lower end of the detection plate 32 is provided with an arc-shaped chamfer 321 facing the transport direction of the transmission mechanism 2, which facilitates the welding joint on the photovoltaic module to enter between the detection plate 32 and the transmission mechanism 2, and avoids the welding joint from contacting and getting stuck with the side wall of the detection plate 32.

[0030] A support plate 362 is arranged on the connecting rod 36. The support plate 362 is located between the fixed plate 31 and the detection plate 32. The support plate 362 is located above the threaded section 361 of the connecting rod 36. One end of the elastic element 35 abuts against the fixed plate 31 and the other end abuts against the support plate 362. The support plate 362 makes it easy for the user to apply force to rotate the connecting rod 36, making the adjustment of the connecting rod 36 convenient.

[0031] A limiting block 363 is arranged on the top of the connecting rod 36, and the limiting block 363 is located above the fixing plate 31.

[0032] The bottom surface of the inspection plate 32 has a receiving groove 322, within which a printing roller 37 is arranged for applying markings to welds that exceed specifications. The printing roller 37 is rotatably connected to the inspection plate 32. Printing ink 38 is arranged within the receiving groove 322, positioned above and in contact with the printing roller 37, serving as supplementary ink for the printing roller 37. The printing roller 37 marks welds that exceed the acceptable range for easy identification and handling by the user. The lowest point of the printing roller 37 is flush with or higher than the bottom surface of the inspection plate 32.

[0033] In another embodiment, such as Figure 4 As shown, rollers 39 are installed on the bottom surface of the detection plate 32. The rollers 39 transform the surface contact between the detection plate 32 and the welding joint into rolling detection, which reduces damage to the detection plate and avoids affecting the detection accuracy. It can also improve the smoothness of detection, making the photovoltaic module transmission smooth.

[0034] When in use, if the welded joint is within the acceptable range when the photovoltaic module is transmitted through the detection mechanism 4 by the transmission mechanism 2, the photovoltaic module 4 will pass directly through the detection mechanism 4 without contacting the detection plate 32. If the welded joint is higher than the acceptable range, the welded joint will push up the detection plate 32, so that after the fixed contact 33 and the moving contact 34 come into contact, they can send a signal that the thickness of the welded joint exceeds the acceptable range, and when passing through the printing roller 37, it will be marked by the printing roller 37.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
