Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic modules, and specifically relates to an automated assembly line testing tool for photovoltaic modules. Background Art

[0002] Solar energy, as a clean energy source, has garnered significant attention in recent years. Photovoltaic manufacturers and researchers are striving to continuously improve the performance and quality of photovoltaic products through process optimization and production process improvements. Electrical performance testing of photovoltaic products is an essential step in ensuring product quality during production. However, with the introduction of automated assembly line testing tools and the rapid evolution of photovoltaic module products, the precise, convenient, non-destructive, and rapid completion of these tests has become a crucial issue in the photovoltaic product manufacturing process. Traditional assembly line operations involve manual testing of modules for voltage withstand safety, electrical performance, and electroluminescence (EL). Testers manually flip the modules onto the test surface, connect the test equipment to the module lead wires, and conduct the tests. With the advancement of intelligent manufacturing in my country, automated assembly line testing tools are beginning to replace manual operations, but this has also brought with it a series of challenges. For example, when the modules are automatically flipped on the assembly line, the freely moving lead wires on the back of the module can easily strike the module backsheet, causing hidden cracks in the cells, affecting the module's electrical performance, and damaging the backsheet's appearance.

[0003] For example, publication number CN207798882U discloses a photovoltaic module automated assembly line test fixture and test device, comprising: a positioning tube; a telescopic tube that slides through the positioning tube and can be used to pass the test cable on the tester; a locking mechanism for preventing the telescopic tube from sliding in the positioning tube; and an adsorbent that is provided on the side wall of the positioning tube and can be adsorbed on the surface of the photovoltaic cell panel. The utility model can be applied to photovoltaic module performance tests on automatic assembly lines, such as insulation withstand voltage tests, EL tests, electrical performance tests, etc., and can effectively prevent the components from being flipped over on the automatic assembly line due to the falling of connecting wires, causing hidden cracks in the components, or even being scrapped. At the same time, the cable telescopic function of the utility model solves the problem of testing difficulties caused by changes in the position of components of different sizes and junction boxes.

[0004] However, in this application, the structure of the adsorbent adsorbed on the surface of the photovoltaic cell panel is unclear, and it is impossible to firmly adsorb the testing device on the surface of the photovoltaic module or to remove the device from the surface. Utility Model Content

[0005] The purpose of this application is to provide a photovoltaic module automated assembly line testing tool in order to solve the above-mentioned problem of firm adsorption and detachment of the adsorption plate.

[0006] The technical solution adopted in this application is as follows: A photovoltaic module automated assembly line test tool, including a positioning tube, a plurality of vacuum adsorption disks are provided on the bottom surface of the positioning tube, the rear end of the positioning tube is connected with a positioning block and a maintenance junction box in sequence, a micro vacuum pump is provided on the surface of the maintenance junction box, a control panel is provided on the surface of the micro vacuum pump, and the micro vacuum pump is connected with a vacuum connecting plate inside the positioning tube, a connecting tube is connected between the vacuum connecting plate and the vacuum adsorption disk, and a snap plate and a block are provided at the surface connection of the vacuum adsorption disk and the positioning tube, and an elastic sealing gasket is provided on the surface of the block of the vacuum adsorption disk.

[0007] By adopting the above technical solution, an adjustable vacuum adsorption disc structure is set up, which not only facilitates the device to firmly adsorb and fix to the photovoltaic module, but also facilitates the detachment of the device. The vacuum adsorption disc forms negative pressure by extracting air to adsorb objects. When the negative pressure is maintained, the object is firmly fixed. When the negative pressure is reduced or disappears, the object will be detached from the disc surface. When the positioning tube and the vacuum adsorption disc on its surface are placed on the surface of the photovoltaic module, they are matched with the micro vacuum pump and the control panel on its surface. The vacuum adsorption disc can be matched with the elastic sealing gasket to maintain negative pressure adsorption and fixation through the vacuum connecting plate and the connecting tube, and the provided clamping block and snap plate facilitate the snap fixation of the structure.

[0008] In a preferred embodiment, a telescopic tube is movably provided inside the positioning tube, and a test cable assembly is provided inside the positioning tube and the telescopic tube.

[0009] By adopting the above technical solution, the arrangement of the positioning tube and the telescopic tube not only facilitates the testing of photovoltaic modules in conjunction with the test cable assembly, but also can correspond to the testing of photovoltaic modules of different sizes.

[0010] In a preferred embodiment, the plurality of vacuum adsorption plates on the bottom surface of the positioning tube are adsorbed onto the surface of the photovoltaic module.

[0011] By adopting the above technical solution, the positioning tube can be fixed on the surface of the photovoltaic module through the adsorption effect of multiple vacuum adsorption disks, thereby facilitating the operation of the automated assembly line.

[0012] In a preferred embodiment, a plurality of positioning holes are formed on the upper surface of the positioning tube.

[0013] By adopting the above technical solution, the multiple positioning holes provided on the surface of the positioning tube facilitate the telescopic positioning of the positioning tube and the telescopic tube.

[0014] In a preferred embodiment, a fixing plate is fixedly provided on the inner surface of the telescopic tube, and a spring is connected to the fixing plate and the surface of the telescopic tube, and the other end of the spring is connected to a pressing protrusion.

[0015] By adopting the above technical solution, the fixing plate arranged inside the telescopic tube cooperates with the spring to facilitate the connection of the pressing protrusion. At the same time, the setting of the spring makes it easy for the positioning tube to slide inside the telescopic tube, and the pressing protrusion will automatically pop out for positioning when it aligns with the positioning hole.

[0016] In a preferred embodiment, the surface of the pressing protrusion is configured as a spherical surface, and the pressing protrusion is correspondingly connected with a positioning hole.

[0017] By adopting the above technical solution, the pressing protrusion arranged for pressing cooperates with its smooth surface to facilitate its fixation or sliding in the middle of the positioning hole.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In the present application, an adjustable vacuum adsorption disc structure is provided, which not only facilitates the device to firmly adsorb to the photovoltaic module but also facilitates the detachment of the device. The vacuum adsorption disc adsorbs objects by extracting air to form negative pressure. When the negative pressure is maintained, the object is firmly fixed. When the negative pressure decreases or disappears, the object is detached from the disc surface. When the positioning tube and the vacuum adsorption disc on its surface are placed on the surface of the photovoltaic module, they are combined with a micro vacuum pump and a control panel on its surface. The vacuum adsorption disc can be combined with an elastic sealing gasket to maintain negative pressure adsorption and fixation through a vacuum connecting plate and a connecting tube, and the provided clamping block and snap plate facilitate the snap fixation of the structure.
