Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic insulation withstand voltage testing technology, and in particular relates to a photovoltaic module testing device. Background Technology

[0002] During the production of photovoltaic modules, insulation and withstand voltage tests are required. Insulation testing involves testing the frame, while withstand voltage testing involves applying high voltage to the junction box. Existing technologies include testing devices that perform both insulation and withstand voltage tests simultaneously. For example, Chinese Patent Publication No. CN117639664A discloses an insulation and withstand voltage testing device and method, which includes a frame with a first testing mechanism and a second testing mechanism located above it. The first and second testing mechanisms have identical structures and can transport photovoltaic modules to either the first or second testing mechanism for testing. Because the first testing... The first or second testing mechanism is fixedly installed at different intervals and at different heights. Therefore, before testing, a first hoist is needed to transport the photovoltaic modules from the first processing line to the first or second testing mechanism for testing. After testing, a second hoist is needed to transport the tested photovoltaic modules from the first or second testing mechanism to the second processing line for unloading. Therefore, when using the above-mentioned insulation withstand voltage testing device, hoists are needed at both ends of the insulation withstand voltage testing device to realize the conveying action. The installation of two hoists results in the entire testing device occupying a large space and increasing the equipment cost.

[0003] Therefore, it is necessary to provide a photovoltaic module testing device to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this invention is to provide a photovoltaic module testing device that is compact in structure, occupies little space, saves costs, and can simultaneously test multiple materials, thereby improving testing efficiency.

[0005] This utility model achieves the above objective through the following technical solution: a photovoltaic module testing device, comprising:

[0006] The testing mechanism has several layers spaced vertically. Each layer of the testing mechanism includes a conveyor line for conveying photovoltaic modules, a correction module for correcting the photovoltaic modules on the conveyor line, and a testing module for testing the corrected photovoltaic modules.

[0007] The lifting unit is used to drive the simultaneous lifting and lowering of several layers of the test mechanism.

[0008] Furthermore, the correction module includes a correction wheel for correcting the photovoltaic module and a correction drive for driving the correction wheel closer to or further away from the photovoltaic module.

[0009] Furthermore, several of the aforementioned alignment wheels are arranged vertically at intervals on a support pole, which is mounted on a movable plate. The movable plate is driven by one of the alignment drive components to move closer to or away from the photovoltaic modules, and the vertically spaced alignment wheels respectively align the photovoltaic modules of each layer.

[0010] Furthermore, the test module includes a first test module for insulation testing of photovoltaic modules and a second test module for withstand voltage testing of photovoltaic modules. The first test module and the second test module of each layer are both located above the conveyor line of that layer.

[0011] Furthermore, the first test module includes a first drive component, a first mounting plate disposed at the active end of the first drive component, a first test drive component disposed on the first mounting plate, a first moving block driven by the first test drive component to move up and down, and a first test probe disposed on the first moving block.

[0012] Furthermore, the second test module includes a second drive component, a second mounting plate disposed at the active end of the second drive component, a second test drive component disposed on the second mounting plate, a second moving block driven by the second test drive component to move up and down, and a second test probe disposed on the second moving block.

[0013] Furthermore, both the first drive assembly and the second drive assembly include a first motor, a moving rod driven by the first motor to move in the X direction, and a second motor disposed on the moving rod. The first mounting plate or the second mounting plate is driven by the second motor to move in the Y direction.

[0014] Furthermore, the lifting unit includes a lifting frame on which several layers of the testing mechanism are installed, and a lifting drive module for driving the lifting frame to perform lifting movements.

[0015] Furthermore, the lifting frame includes several layers of horizontal beams spaced apart vertically, and the test module of the test mechanism and the conveyor line of each layer are respectively set on the two adjacent layers of horizontal beams.

[0016] Furthermore, the lifting drive module includes a third motor, a drive shaft driven by the third motor to rotate, and a first driven shaft and a second driven shaft disposed above the drive shaft. A first transmission wheel is disposed on the drive shaft, a second transmission wheel is disposed on the first driven shaft, and a third transmission wheel is disposed on the second driven shaft. A first transmission component is disposed on the first transmission wheel and the second transmission wheel to realize rotational transmission. One end of the first transmission component is fixedly connected to the left end of the lifting frame. A second transmission component is disposed between the second transmission wheel and the third transmission wheel to realize rotational transmission. A third transmission component is also disposed on the third transmission wheel, and one end of the third transmission component is fixedly connected to the right end of the lifting frame.

[0017] Compared with existing technologies, the advantages of this photovoltaic module testing device are as follows: the lifting unit can drive several layers of testing mechanisms to move up and down simultaneously, aligning with the processing conveyor line to receive the photovoltaic modules to be tested or output the tested photovoltaic modules. This eliminates the need for a separate lifting machine for conveying operations, reducing the overall length of the testing device. Therefore, the testing device of this solution has a compact structure, occupies little space, and saves equipment costs. Furthermore, the device features several layers of testing mechanisms, and when one layer is being tested, the lifting unit can drive the lifting frame to raise all layers of testing mechanisms simultaneously, aligning the conveyor line of the next layer with the processing conveyor line to receive the photovoltaic modules to be tested. This enables multiple layers of testing mechanisms to perform testing actions simultaneously, allowing for the simultaneous testing of multiple photovoltaic modules, improving the testing cycle time and efficiency.

Detailed Implementation

[0028] Please refer to Figures 1-6 This embodiment is a photovoltaic module testing device 100, which includes:

[0029] The testing mechanism 1 has several layers spaced vertically. Each layer of the testing mechanism 1 includes a conveyor line 11 for conveying photovoltaic modules, a correction module 12 for correcting the photovoltaic modules on the conveyor line 11, and a testing module 13 for testing the corrected photovoltaic modules.

[0030] Lifting unit 2 is used to drive several layers of testing mechanism 1 to move up and down simultaneously.

[0031] In this embodiment, a photovoltaic module is being tested. In other embodiments, the same testing machine can be used to test other products, by simply replacing the test module 13 accordingly.

[0032] In this embodiment, three layers of testing mechanisms 1 are arranged at vertical intervals, allowing simultaneous testing of three photovoltaic modules. In other embodiments, multiple layers of testing mechanisms 1 may be provided depending on the actual situation; the number of layers of testing mechanisms 1 is not limited in this embodiment.

[0033] The conveyor line 11 includes a conveyor drive unit 111, a rotating shaft 112 driven by the conveyor drive unit 111, a conveyor wheel mounted on the rotating shaft 112, and a conveyor belt 113 wound around the conveyor wheel. The conveyor drive unit 111 is preferably a servo motor to ensure conveying accuracy; multiple conveyor belts 113 are provided to ensure conveying stability.

[0034] In this embodiment, two alignment modules 12 are respectively disposed on the left and right sides of the module assembly feed line 11 to align the two opposite sides of the photovoltaic module. The alignment module 12 includes an alignment wheel 121 for aligning the sides of the photovoltaic module and an alignment drive component 122 for driving the alignment wheel 121 closer to or further away from the photovoltaic module.

[0035] In this embodiment, the correction drive 122 can be configured as a servo motor or a cylinder, preferably a servo motor. This allows for one-click switching when changing the size of the photovoltaic module, saving time on position adjustment and improving the versatility of the testing device. In other embodiments, the correction drive 122 can be configured with other driving methods; this embodiment does not impose any limitations.

[0036] In this embodiment, a three-layer test mechanism 1 is provided. Therefore, three sets of correction modules 12 are provided accordingly, and the three sets of correction modules 12 are arranged vertically and horizontally. If each set of correction modules 12 includes a correction drive 122 and a correction wheel 121, then three correction drive 122s are required to drive the correction wheel 121 to move closer to or away from the photovoltaic module. Since the three correction wheels 121 only move closer to or away from the photovoltaic module to achieve the correction action, this action is relatively simple. Setting three correction drive 122s would make the structure complex. To simplify the structure of the alignment module 12, several alignment wheels 121 are arranged vertically at intervals on a support rod 123. The support rod 123 is mounted on a movable plate 124. The movable plate 124 is driven by an alignment drive 122 to move closer to or away from the photovoltaic module. The vertically at intervals of the alignment wheels 121 simultaneously align each layer of photovoltaic modules. Therefore, one alignment drive 122 can simultaneously align several layers of photovoltaic modules, ensuring the consistency of alignment for several layers of photovoltaic modules. Furthermore, it simplifies the structure of the alignment module 12, reduces the number of alignment drive 122, and lowers the cost of the testing device.

[0037] In this embodiment, three alignment rollers 121 are provided at the top, middle, and bottom positions of the support pole 123 to align the photovoltaic modules on the three-layer conveyor line 11. In other embodiments, the number of alignment rollers 121 can be provided on the support pole 123 according to the number of layers of the testing mechanism 1. Several alignment rollers 121 provided at the top and bottom can simultaneously align the photovoltaic components on the multi-layer conveyor line 11. The number of alignment rollers 121 provided on each support pole 123 is not limited.

[0038] In other embodiments, the front end of the conveyor line 11 is further provided with a blocking component to prevent the photovoltaic modules from continuing to be conveyed forward, and the rear end of the conveyor line is provided with a straightening component to straighten the rear end of the photovoltaic modules. The blocking component and the straightening component can adopt the design of the prior art, and will not be described in detail here.

[0039] The test module 13 includes a first test module 131 for insulation testing of the photovoltaic module and a second test module 132 for withstand voltage testing of the photovoltaic module. The first test module 131 and the second test module 132 of each layer are both located above the conveyor line 11 of that layer. In this embodiment, four first test modules 131 are provided for each layer, and these four first test modules 131 are respectively located at the four corners of the conveyor line 11 to perform insulation testing on the four edges of the photovoltaic module. Two second test modules 132 are provided for each layer, located at the front and back, respectively located in the middle above the conveyor line 11 to perform high voltage testing on the junction box of the photovoltaic module. In other embodiments, the number and position of the first test module 131 and the second test module 132 can be set according to actual conditions and are not limited here.

[0040] The first test module 131 includes a first drive component 1311, a first mounting plate 1312 disposed at the active end of the first drive component 1311, a first test drive component 1313 disposed on the first mounting plate 1312, a first moving block 1314 driven by the first test drive component 1313 to move up and down, and a first test probe 1315 disposed on the first moving block 1314.

[0041] The second test module 132 includes a second drive assembly 1321, a second mounting plate 1322 disposed at the active end of the second drive assembly 1321, a second test drive component 1323 disposed on the second mounting plate 1322, a second moving block 1324 driven by the second test drive component 1323 to move up and down, and a second test probe 1325 disposed on the second moving block 1324.

[0042] In this embodiment, the first test drive unit 1313 and the second test drive unit 1323 can be configured as a cylinder or a servo motor, depending on the actual situation. If the photovoltaic modules have the same height, the probe will move up and down a consistent distance, so a cylinder is preferred to save costs. If the photovoltaic modules have different thicknesses, the probe will move up and down a different distance, so a servo motor is preferred. A sensor is used to detect the position of the photovoltaic modules, and then the servo motor drives the probe to move up and down to contact the photovoltaic modules for testing. In other embodiments, the first test drive unit 1313 and the second test drive unit 1323 can be configured as other drive units, which are not limited here.

[0043] To improve the versatility of the testing device and enable the first test module 131 and the second test module 132 to test photovoltaic modules of different lengths and widths, the first drive component 1311 needs to be able to drive the first test probe 1315 to move in the X and Y directions, and the second drive component 1321 needs to be able to drive the second test probe 1325 to move in the X and Y directions, so as to adapt to photovoltaic modules of different lengths and widths. Both the first drive component 1311 and the second drive component 1321 include a first motor 13111, a moving rod 13112 driven by the first motor 13111 to move in the X direction, and a second motor 13113 mounted on the moving rod 13112. The first mounting plate 1312 or the second mounting plate 1322 is driven by the second motor 13113 to move in the Y direction. In this embodiment, two second test modules 132 are arranged front and rear, and the two second test modules 132 share a single moving rod 13112, enabling the two second test modules 132 to move in the X direction simultaneously. In other embodiments, multiple second test modules 132 may be set to move simultaneously or at different times, depending on the actual situation, and no restrictions are imposed here.

[0044] The lifting unit 2 includes a lifting frame 21 on which several layers of testing mechanisms 1 are installed, and a lifting drive module 22 that drives the lifting frame 21 to move up and down. The lifting drive module 22 is installed on the frame 23. The lifting frame 21 is movably mounted on the frame 23 by means of a slide rail slider, or the lifting frame 21 is movably mounted on the frame 23 by means of a pulley and slide groove, or the lifting frame 21 is movably mounted on the frame 23 by a combination of both. This is set according to the actual situation and is not limited here.

[0045] The lifting frame 21 has a square frame structure and includes several layers of horizontal beams 211 arranged at intervals. Each layer of horizontal beams 211 has two beams arranged at the front and back. The test module 13 and the conveyor line 11 of the test mechanism 1 in each layer are respectively arranged on the upper and lower adjacent layers of horizontal beams 211. The test module 13 is arranged on the upper layer of horizontal beams 211 of the two adjacent layers of horizontal beams 211 and the probe extends downward. The conveyor line 11 is arranged on the lower layer of horizontal beams 211 of the two adjacent layers of horizontal beams 211 and the conveyor belt 113 is located above the lower layer of horizontal beams 211. The photovoltaic module passes through the upper and lower adjacent layers of horizontal beams 211 and is located between the test module 13 and the conveyor line 11.

[0046] To make the overall structure more compact and occupy less space, in this embodiment, the number of layers of the crossbeam 211 is one more than the number of layers of the testing mechanism 1. The top layer of the crossbeam 211 only has the testing module 13 with the probe extending downwards, and the bottom layer of the crossbeam 211 only has the conveyor line 11 with the conveyor belt 113 located above the crossbeam 211. The middle layer of the crossbeam 211 has both the testing module 13 and the conveyor line 11, with the conveyor line 11 positioned above the testing module 13, i.e., the testing module 13 and the conveyor line 11 are arranged vertically and horizontally. In this embodiment, there are three layers of the testing mechanism 1, with a total of four layers of crossbeams 211. The top layer of the crossbeam 211 only has the testing module 13, the bottom fourth layer only has the conveyor line 11, and the middle second and third layers of the crossbeam 211 both have both the testing module 13 and the conveyor line 11. In other embodiments, the number of layers of the crossbeam 211 is adapted to the number of layers of the testing mechanism 1, and is not limited here.

[0047] The conveyor line 11 is fixedly mounted on the crossbeam 211. The first motor 13111 of the first drive assembly 1311 and the first motor 13111 of the second drive assembly 1321 are both mounted on the crossbeam 211, and the moving rod 13112 and the moving plate 124 are movably mounted on the crossbeam 211 by means of a slide rail slider.

[0048] In this embodiment, the lifting drive module 22 includes a third motor 221, a drive shaft 222 driven by the third motor 221 to rotate, and a first driven shaft 223 and a second driven shaft 224 disposed above the drive shaft 222. A first transmission wheel 225 is disposed on the drive shaft 222, a second transmission wheel 226 is disposed on the first driven shaft 223, and a third transmission wheel 227 is disposed on the second driven shaft 224. A first transmission member 228 is disposed on the first transmission wheel 225 and the second transmission wheel 226 to realize rotational transmission. One end of the first transmission member 228 is fixedly connected to the left end of the lifting frame 21. A second transmission member 229 is disposed between the second transmission wheel 226 and the third transmission wheel 227 to realize rotational transmission. A third transmission member 2210 is also disposed on the third transmission wheel 227, and one end of the third transmission member 2210 is fixedly connected to the right end of the lifting frame 21. In this embodiment, the first transmission wheel 225, the second transmission wheel 226, and the third transmission wheel 227 are all sprockets, and correspondingly, the first transmission component 228, the second transmission component 229, and the third transmission component 2210 are all chains. In other embodiments, the first transmission wheel 225, the second transmission wheel 226, and the third transmission wheel 227 are all pulleys, and correspondingly, the first transmission component 228, the second transmission component 229, and the third transmission component 2210 are all transmission belts.

[0049] In other embodiments, the lifting drive module 22 may be provided with other structures. As long as it can drive the lifting frame 21 to perform lifting movements, the structure of the lifting drive module 22 can be adjusted according to the actual space. The structure of the lifting drive module 22 is not limited here.

[0050] When using the photovoltaic module testing device 100 provided in this solution, the lifting unit 2 drives the lifting frame 21 to descend so that the conveyor line 11 of the uppermost testing mechanism 1 is aligned with the processing conveyor line. The photovoltaic module is conveyed onto the conveyor line 11 of the uppermost testing mechanism 1. The correction drive 122 drives the moving plate 124 to move the correction wheel 121 to the side of the photovoltaic module. The correction wheels 121 on both sides correct the side of the photovoltaic module. After the correction module 12 completes the correction, it resets. The first testing module 131 and the second testing module 132 of the uppermost testing mechanism 1 perform testing simultaneously. The first testing drive 131... 3. Drive the first moving block 1314 to descend, causing the first test probe 1315 to extend into the test hole of the frame for insulation testing. The second test drive unit 1323 drives the second moving block 1324 to descend, causing the second test probe 1325 to extend into the junction box for high-voltage testing. When the test module 13 of the uppermost test mechanism 1 is working, the lifting unit 2 drives the lifting frame 21 to rise, making the conveyor line 11 of the second-layer test mechanism 1 flush with the processing conveyor line. The alignment module 12 of the second-layer test mechanism 1 completes the alignment action, and the test module 13 performs the test action. The test action is the same as described above and will not be repeated. When the test module 13 of the third-layer test mechanism 1 is being tested, the lifting unit 2 drives the lifting frame 21 to rise, making the conveyor line 11 of the third-layer test mechanism 1 level with the processing conveyor line. The alignment module 12 of the third-layer test mechanism 1 completes the alignment action, and the test module 13 performs the testing action. This process is repeated until the test module 13 of the bottom layer test mechanism 1 is being tested. At this time, the lifting unit 2 drives the lifting frame 21 to descend, making the conveyor line 11 of the top layer test mechanism 1 level with the processing conveyor line. The conveyor line 11 transports the photovoltaic modules that have completed testing of the top layer test module 13 to the subsequent workstation, while simultaneously transporting the modules to be tested... The photovoltaic modules are conveyed to the conveyor line 11 of the top-level testing mechanism 1. The alignment module 12 of the top-level testing mechanism 1 completes the alignment action, and the testing module 13 performs the testing action. At the same time, the lifting unit 2 drives the lifting frame 21 to rise so that the conveyor line 11 of the second-level testing mechanism 1 is aligned with the processing conveyor line. The conveyor line 11 conveys the photovoltaic modules that have been tested by the second-level testing module 13 to the subsequent workstations, and at the same time conveys the photovoltaic modules to be tested to the conveyor line 11 of the second-level testing mechanism 1, until the photovoltaic modules that have been tested at the bottom are conveyed. The photovoltaic modules to be tested are then placed in the conveyor line 11, and the above actions are repeated to test the photovoltaic modules.

[0051] The lifting unit 2 can drive several layers of testing mechanisms 1 to move up and down, aligning with the processing conveyor line to receive the photovoltaic modules to be tested. This eliminates the need for a separate lifting machine for conveying operations, reducing the overall length of the testing machine. The testing machine structure of this solution is compact, occupies little space, and saves equipment costs. Moreover, when the upper layer of testing mechanism 1 is being tested, the lifting unit 2 can drive the lifting frame 21 to lift several layers of testing mechanism 1 simultaneously, so that the conveyor line 11 of the lower layer of testing mechanism 1 is aligned with the processing conveyor line to receive the photovoltaic modules to be tested. This enables simultaneous testing of multiple layers of testing mechanism 1 and simultaneous testing of multiple photovoltaic modules, improving the testing cycle and efficiency.

[0052] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
