Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a photovoltaic module follow-up power-on device. Background Technology
[0002] After undergoing a series of manufacturing processes on the production line, photovoltaic (PV) modules need to complete finished product inspections, including insulation withstand voltage tests, grounding continuity tests, and IV tests. These tests measure electrical performance parameters to classify different PV modules before they can be officially shipped. Before these finished product inspections, an electrical connection fixture needs to be installed on the PV modules. By connecting the male and female connectors in the junction box of the PV module to the electrical connection fixture, a circuit loop is formed. Then, power is applied to the copper blocks at both ends of the electrical connection fixture to perform a power-on test on the PV module.
[0003] Furthermore, since photovoltaic modules also undergo simultaneous photo-taking and other inspections on the production line, the current power-on method involves setting up three sets of power-on blocks at intervals on the production line. The photovoltaic modules are then conveyed linearly along the belt conveyor to each power-on block for a power-on test. However, this method requires a cylinder to move the power-on block up and down once at each location to complete one power-on test. The entire power-on test process requires the cylinder to move the power-on block up and down three times, resulting in numerous cylinder movements and a long testing time. With increasingly fierce market competition, photovoltaic module manufacturers are demanding higher production line speeds to increase daily production capacity. The existing photovoltaic module power-on testing method clearly no longer meets the production needs of photovoltaic module manufacturers. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a photovoltaic module follow-up power-on device that can improve production cycle and meet actual production needs.
[0005] The present invention adopts the following technical solution:
[0006] This utility model provides a photovoltaic module follow-up power-on device, including a connecting frame, a lifting component, a reset component, a clamping component, and a controller. The connecting frame is fixedly installed and is equipped with a position detection component and a laterally extending linear guide rail. The lifting component is slidably mounted on the linear guide rail and is in contact with the position detection component in its initial position. The reset component is mounted on the connecting frame and can push the lifting component to move laterally to the initial position. The clamping component is connected to the lifting component and moves up and down vertically under the drive of the lifting component. Two power-on blocks are arranged laterally at intervals on the clamping component. The two power-on blocks can contact the male and female heads of the power-on fixture to form a circuit loop. The lifting component, reset component, clamping component, and position detection component are all signal connected to the controller.
[0007] Preferably, the lifting assembly includes a slide table and a slide table cylinder. The slide table is slidably mounted on a linear guide rail and is in contact with the positioning detection assembly in its initial position. The slide table cylinder is mounted on the slide table and connected to the clamping assembly via a drive end. The slide table cylinder is also connected to the controller signal.
[0008] Preferably, the reset assembly includes a push plate and a servo motor. The push plate is slidably mounted on a linear guide rail, and the servo motor is fixed on a connecting frame and drives the push plate to reciprocate laterally. The servo motor is connected to the controller via a signal.
[0009] Preferably, the clamping assembly includes a pneumatic gripper and a bar frame. The pneumatic gripper is connected to the lifting assembly and is also connected to the controller signal. The bar frame is fixed on the pneumatic gripper, and the power block is locked and fixed in the transverse slide groove of the bar frame.
[0010] Preferably, the two gripping claws on the pneumatic gripper have cushioning pads fixed on their opposing inner surfaces.
[0011] Preferably, the positioning detection component includes a fixed block, a proximity sensor, and a stop positioning screw. The fixed block is fixed on the connecting frame, and the proximity sensor and the stop positioning screw are both mounted on the fixed block. The lifting component is in contact with the stop positioning screw in its initial position.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model's photovoltaic module follow-up power-on device can move the photovoltaic module to the initial position of the lifting component when the production line belt conveyor moves the photovoltaic module. The lifting component then drives the clamping component downward, causing the two power-on blocks on the clamping component to contact the male and female heads of the power-on fixture to form a circuit loop. This causes the clamping component to close and clamp the power-on fixture. The first power-on test is performed simultaneously during the closure of the clamping component. After the first power-on test, the belt conveyor continues to move the photovoltaic module to the second power-on position, and the clamping component moves synchronously under the belt conveyor. Upon reaching the second power-on position, no further movement or waiting is required, and the second power-on test can be performed directly. Then, the clamping component continues to move with the photovoltaic module to the third power-on position, where power-on testing can begin immediately. Finally, after completing the third power-on test, the controller controls the clamping component to release the power-on fixture and simultaneously controls the lifting component to raise the clamping component, thus completing the entire power-on test process for the photovoltaic module. Afterward, the reset component pushes the lifting component to move laterally back to the initial position, ready to wait for the next photovoltaic module's power-on test.
[0014] Obviously, the photovoltaic module follow-up power-on device of this utility model only needs to perform one up-and-down movement of the power-on block during the entire power-on test process, which saves two up-and-down movements of the power-on block compared with the existing power-on method. This can improve the rhythm of production line equipment, increase the daily production capacity of the production line, and achieve the purpose of improving production efficiency and reducing production costs to meet actual production needs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0032] See Figure 1 This embodiment provides a photovoltaic module follow-up power-on device, including a connecting frame 1, a lifting component 2, a reset component 3, a clamping component 4, and a controller. The connecting frame 1 is fixedly installed and is equipped with a position detection component 5 and a laterally extending linear guide rail 6. The lifting component 2 is slidably installed on the linear guide rail 6 and is in contact with the position detection component 5 in its initial position. The reset component 3 is installed on the connecting frame 1 and can push the lifting component 2 to move laterally to the initial position. The clamping component 4 is connected to the lifting component 2 and moves up and down in the vertical direction under the drive of the lifting component 2. Two power-on blocks 401 are arranged laterally at intervals on the clamping component 4. The two power-on blocks 401 can contact the male and female heads of the power-on fixture to form a circuit loop. The lifting component 2, the reset component 3, the clamping component 4, and the position detection component 5 are all signal connected to the controller.
[0033] In this embodiment, the photovoltaic module follow-up power-on device can move the photovoltaic module to the initial position of the lifting component 2 when the production line belt conveyor moves the photovoltaic module. The lifting component 2 then drives the clamping component 4 downwards, causing the two power-on blocks 401 on the clamping component 4 to contact the male and female heads of the power-on fixture to form a circuit. This closes the clamping component 4, clamping the power-on fixture. The first power-on test is performed synchronously during the closing of the clamping component 4. After the first power-on test, the belt conveyor continues to move the photovoltaic module to the second power-on position, and the clamping component 4 also moves synchronously under the drive of the belt conveyor. Then, upon reaching the second power-on position, no further movement or waiting is required; the second power-on test can proceed directly. Next, clamping component 4 continues to move with the photovoltaic module to the third power-on position, where it can be immediately powered on for testing. Finally, after completing the third power-on test, the controller controls clamping component 4 to release the power-on fixture and simultaneously controls lifting component 2 to raise clamping component 4, thus completing the entire power-on test process for the photovoltaic module. Afterward, reset component 3 pushes lifting component 2 horizontally back to its initial position, ready to await the next photovoltaic module's power-on test.
[0034] Obviously, the photovoltaic module follow-up power-on device in this embodiment only needs to perform one up-and-down movement of the power-on block during the entire power-on test process, which saves two up-and-down movements of the power-on block compared to the existing power-on method, thereby saving about two seconds of power-on test time. This can improve the rhythm of production line equipment, increase the daily production capacity of the production line, and achieve the purpose of improving production efficiency and reducing production costs to meet actual production needs.
[0035] It should be noted that, in use, the photovoltaic module follow-up power-on device of this embodiment can also be connected to the slider of the guide rail slider assembly on the production line through the connecting frame 1, so that the setting position of the photovoltaic module follow-up power-on device can be adjusted by means of the guide rail slider assembly, which facilitates the fixing of the power-on block 401. In addition, the production line is equipped with a sensor. When the photovoltaic module moves to the initial position of the lifting assembly 2, the sensor senses that the power-on fixture is in place and sends the relevant signal to the controller. Then the controller controls the operation of the photovoltaic module follow-up power-on device of this embodiment.
[0036] Preferably, in this embodiment, the controller is a PLC controller.
[0037] Preferably, see Figure 2 The lifting assembly 2 includes a slide table 201 and a slide table cylinder 202. The slide table 201 is slidably mounted on the linear guide rail 6, and the slide table 201 is in contact with the positioning detection assembly 5 in the initial position. The slide table cylinder 202 is mounted on the slide table 201 and connected to the clamping assembly 4 through the drive end. The slide table cylinder 202 is also connected to the controller signal.
[0038] After the clamping assembly 4 closes and clamps the electrical fixture, the belt conveyor drives the photovoltaic module to move, while the slide table 201 on the lifting assembly 2 also slides along the linear guide rail 6 under the drive of the belt conveyor, thereby realizing the synchronous movement of the clamping assembly 4 under the drive of the belt conveyor. In addition, the slide table cylinder 202 on the lifting assembly 2 can drive the clamping assembly 4 to move up and down in the vertical direction through the drive end.
[0039] Preferably, see Figure 3 The reset assembly 3 includes a push plate 301 and a servo motor 302. The push plate 301 is slidably mounted on the linear guide rail 6. The servo motor 302 is fixed to the connecting frame 1 and drives the push plate 301 to move laterally back and forth. The servo motor 302 is signal-connected to the controller. After the entire power-on test of the photovoltaic module is completed, the controller controls the servo motor 302 to drive the push plate 301 to move laterally on the linear guide rail 6, thereby pushing the lifting assembly 2 to the initial position.
[0040] Preferably, see Figure 2 The clamping assembly 4 includes a pneumatic gripper 402 and a strip frame 403. The pneumatic gripper 402 is connected to the lifting assembly 2 and is also signal-connected to the controller. The strip frame 403 is fixed on the pneumatic gripper 402, and the upper electric block 401 is locked and fixed in the transverse slide groove of the strip frame 403. When the clamping assembly 4 closes to clamp the upper electric fixture, the clamping of the upper electric fixture can be completed by controlling the pneumatic gripper 402 to close. The setting of the strip frame 403 makes the transverse position of the upper electric block 401 adjustable. By loosening the upper electric block 401, the position of the upper electric block 401 in the transverse slide groove of the strip frame 403 can be adjusted to adapt to the position of the male and female heads on the upper electric fixture.
[0041] Preferably, see Figure 2 The two gripping jaws on the pneumatic gripper 402 have buffer pads 404 fixed on their opposite inner sides to prevent the pneumatic gripper 402 from clamping and damaging the upper electrical fixture.
[0042] Preferably, see Figure 2 The positioning detection component 5 includes a fixed block 501, a proximity sensor 502, and a stop positioning screw 503. The fixed block 501 is fixed to the connecting frame 1. The proximity sensor 502 and the stop positioning screw 503 are both mounted on the fixed block 501. The lifting component 2 is in contact with the stop positioning screw 503 in its initial position. The proximity sensor 502 can sense that the power-on block 401 has returned to its initial origin position and transmit the information to the controller to start the power-on detection of the next photovoltaic module. The stop positioning screw 503 can accurately position the initial origin position of the power-on block 401.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
