Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing technology, and in particular to a testing device and a photovoltaic module processing system. Background Technology

[0002] After the photovoltaic modules are installed in the junction box, the junction box needs to be soldered to the busbars (hereinafter referred to as leads) extending from the module. If the soldering is not secure, the connection between the lead and the junction box may fail or completely disconnect, causing abnormal equipment operation or even malfunction. Therefore, the leads need to be tested after soldering to verify the reliability of the connection. Currently, this test mainly relies on manual operation using tools, which has the following drawbacks:

[0003] 1. Low efficiency and high cost: Manual sorting is much slower than automated equipment. Additional inspection personnel are needed to match the production line rhythm, which significantly increases labor and manufacturing costs.

[0004] 2. Poor quality consistency: Long-term operation can easily lead to employee fatigue and distraction, resulting in missed defects such as incomplete soldering and desoldering, making it difficult to guarantee product yield.

[0005] 3. Unstable force control: The force applied manually varies greatly. Excessive prodding may damage the lead wire, while insufficient force will not effectively expose potential welding defects. Utility Model Content

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] like Figures 1 to 5 As shown, one embodiment of this application provides a testing device 10, which is used to test the welding quality of the lead 20a of the photovoltaic module 20 to the junction box 30 (see...). Figure 6 ).like Figures 1 to 5 As shown, the testing device 10 includes a transfer module 100 and at least one testing body 200. The testing body 200 includes a mounting base 210, a pressing member 220, and a propelling member 230. The transfer module 100 can drive the mounting base 210 to move along the X-axis, Y-axis, or Z-axis. The pressing member 220 is disposed on the mounting base 210 and can press the junction box 30. The propelling member 230 is disposed on the mounting base 210 and can move along the Y-axis to insert between the junction box 30 and the lead 20a of the photovoltaic module 20. The propelling member 230 can also propel the lead 20a of the photovoltaic module 20. The directions of "X-axis," "Y-axis," and "Z-axis" in the text refer to... Figure 1 The information shown shall prevail.

[0043] The testing device 10 can be installed on the production line of the photovoltaic module 20. Specifically, it can be installed at the welding quality inspection station downstream of the welding station on the production line. At the welding station, the lead wire 20a of the photovoltaic module 20 extends into the junction box 30 and is welded to the conductive terminal 30a (see...). Figure 7 ).

[0044] After the photovoltaic module 20 and junction box 30 are welded and transported from the welding station to the welding quality inspection station, the transfer module 100 drives the inspection body 200 to move along the X-axis or Y-axis. When the inspection body 200 moves directly above the junction box 30, the transfer module 100 drives the inspection body 200 to move downward along the Z-axis. Of course, when the inspection body 200 moves along the X-axis or Y-axis, the transfer module 100 can also simultaneously drive the inspection body 200 to move along the Z-axis until the pressing member 220 presses against the junction box 30. This prevents the parts of the photovoltaic module 20 located around the junction box 30 from being pulled when the leads 20a of the photovoltaic module 20 are subsequently moved, which would affect the performance of the photovoltaic module 20. When the pressing member 220 presses against the junction box 30, the propelling member 230 moves along the Y-axis between the junction box 30 and the lead 20a of the photovoltaic module 20. After the propelling member 230 is inserted between the junction box 30 and the lead 20a of the photovoltaic module 20, it will prod the lead 20a of the photovoltaic module 20. It should be noted that the insertion position of the propelling member 230 between the junction box 30 and the lead 20a of the photovoltaic module 20 must be close to the welding position between the conductive terminal 30a of the junction box 30 and the lead 20a of the photovoltaic module 20. Afterwards, observe whether there are cracks in the welding position between the conductive terminal 30a of the junction box 30 and the lead 20a of the photovoltaic module 20, or use other methods to determine whether the connection between the lead 20a of the photovoltaic module 20 and the junction box 30 is reliable.

[0045] The detection device 10 provided in this embodiment can automatically adjust the lead 20a of the photovoltaic module 20 after it has been soldered to the junction box 30. This adjustment is achieved by using a probing component 230 to determine whether the connection between the lead 20a and the junction box 30 is reliable. During the adjustment process, the pressing component 220 presses the junction box 30, preventing the parts of the photovoltaic module 20 located around the junction box 30 from being pulled and affecting the performance of the photovoltaic module 20. For example, it can prevent the solar cells of the photovoltaic module 20 from developing microcracks under external force. Therefore, this detection device 10 can automatically adjust the lead 20a of the photovoltaic module 20 without relying on manual adjustment. This improves efficiency, reduces costs, lowers the false negative rate, ensures product yield, and effectively controls the adjustment force to avoid damaging the lead 20a of the photovoltaic module 20, while also preventing damage to the solar cells of the photovoltaic module 20.

[0046] The pressing member 220 of the detection body 200 is used to press the junction box 30 on the photovoltaic module 20 when the lead 20a of the photovoltaic module 20 is provoked, as in some embodiments of this application, such as Figures 3 to 5 As shown, there are two pressing members 220. The two pressing members 220 can move towards each other along the Y-axis and can press the opposite ends of the junction box 30. If the pressing member 220 only presses one end of the junction box 30, while the other end is pulled when the lead 20a of the photovoltaic module 20 is provoked, there is a risk of microcracks in the cells of the photovoltaic module 20. Therefore, two pressing members 220 are provided to firmly press the junction box 30.

[0047] When the detection body 200 moves downward along the Z-axis directly above the junction box 30, the two pressing parts 220 are moved closer to each other until they reach the positions that press the opposite ends of the junction box 30. After the welding quality inspection is completed, the two pressing parts 220 are moved away from each other.

[0048] See Figure 5 In some embodiments of this application, the pressing member 220 has a first pressing surface 221 and a second pressing surface 222 distributed along the Z-axis. The first pressing surface 221 is used to press against the junction box 30, and the second pressing surface 222 is used to press against the photovoltaic module 20. With this configuration, the pressing member 220 can firmly press the junction box 30 onto the photovoltaic module 20. The junction box 30 is typically located on the back of the photovoltaic module 20; therefore, as an example, the second pressing surface 222 is used to press against the back of the photovoltaic module 20.

[0049] The second pressing surface 222 is an arc-shaped convex surface. This prevents the pressing part 220 from scratching the photovoltaic module 20.

[0050] See also Figure 5 The pressing member 220 also has a receiving groove 223 for receiving the lead wire passing block 30b of the junction box 30 (see Figure 8 And adjacent to the second pressing surface 222. The receiving groove 223 is used to receive the lead wire passing block 30b of the junction box 30, so that the pressing member 220 can firmly press the junction box 30 onto the photovoltaic module 20. The receiving groove 223 can be an arc-shaped groove. The groove wall of the arc-shaped groove is relatively smooth, which can avoid scratching the lead wire passing block 30b of the junction box 30. Specifically, the receiving groove 223 can be set as a quarter arc-shaped groove.

[0051] The pressing part 220 can be made of rigid materials such as cast iron and stainless steel. The length can be set to 40mm to 50mm (e.g., 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, 50mm, etc.), and the width can be set to 10mm to 20mm (e.g., 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.).

[0052] See Figures 3 to 5 In some embodiments of this application, the detection body 200 further includes a pneumatic finger mechanism 240 disposed on the mounting base 210. The pneumatic finger mechanism 240 has two fingers that move toward each other along the Y-axis, and the fingers are connected to corresponding pressing members 220. The pneumatic finger mechanism 240 can automatically drive the two pressing members 220 to move toward each other along the Y-axis. Only one power mechanism is needed to drive the movement of the two pressing members 220, which simplifies the structure of the device and reduces the cost of use.

[0053] Of course, in some other embodiments, the detection body 200 may be provided with two power mechanisms, each power mechanism being used to drive the corresponding pressing member 220. The power mechanism may be a power cylinder such as a pneumatic cylinder or a hydraulic cylinder, or it may be a power mechanism composed of a motor and a transmission assembly.

[0054] The probing element 230 of the detection body 200 is used to prod the lead 20a of the photovoltaic module 20, such as... Figures 3 to 5 As shown, in some embodiments of this application, the propelling element 230 includes a force-controlled motor 231 and a propelling finger 232. The force-applying end of the force-controlled motor 231 is connected to the propelling finger 232 and can provide a preset propelling force to the propelling finger 232. After the propelling finger 232 of the propelling element 230 is inserted between the junction box 30 and the lead 20a of the photovoltaic module 20, the force-controlled motor 231 provides a preset propelling force to the propelling finger 232, causing the propelling finger 232 to propel the lead 20a of the photovoltaic module 20. The force-controlled motor 231 can precisely control the force of the propelling finger 232, preventing defective parts from leaking out and avoiding damage to the lead 20a of the photovoltaic module 20.

[0055] The 231 force-controlled motor is a precision force-controlled motor. Compared to ordinary force-controlled motors, precision force-controlled motors have higher accuracy and can meet the requirements of various applications.

[0056] The dimensions of the probing finger 232 can be set according to requirements, as long as it can meet the normal probing function. For example, the length of the probing finger 232 can be set to 30mm to 50mm (e.g., 30mm, 35mm, 40mm, 45mm, 50mm, etc.), and the width can be set to 3mm to 5mm (e.g., 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc.).

[0057] The probing finger 232 protrudes downward along the Z-axis relative to the pressing member 220. This arrangement allows the pressing member 220 to press the top cover of the junction box 30, while the probing finger 232 can extend into the junction box 30 to prod the leads 20a of the photovoltaic module 20. The length of the probing finger 232 protruding downward along the Z-axis relative to the pressing member 220 can be set to 5mm to 15mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0058] The propellant finger 232 has a pointed head 2321 extending along the Y-axis at one end away from the force control motor 231 (see [reference]). Figure 5 The pointed tip 2321 is designed to facilitate the insertion of the finger 232 between the junction box 30 and the lead 20a of the photovoltaic module 20 without damaging the lead 20a of the photovoltaic module 20.

[0059] Junction box 30 typically contains a positive conductive terminal and a negative conductive terminal. The positive conductive terminal connects to the positive lead of photovoltaic module 20, and the negative conductive terminal connects to the negative lead of photovoltaic module 20. That is, junction box 30 has two points where it needs to be soldered to lead 20a of photovoltaic module 20. Regarding this, if... Figures 3 to 5 As shown, in some embodiments of this application, two propellants 230 are provided, and the two propellants 230 are spaced apart along the Y-axis. One propellant 230 is used to propel the positive lead of the photovoltaic module 20, and the other propellant 230 is used to propel the negative lead of the photovoltaic module 20. The two propellants 230 can work simultaneously, which can reduce the inspection time of welding quality and improve inspection efficiency. The pointed head 2321 of the propellant 230 extends towards the other propellant 230.

[0060] To further improve the efficiency of welding quality inspection, the number of inspection bodies 200 can be set according to the number of junction boxes 30 on the photovoltaic module 20, so that one inspection body 200 corresponds to one junction box 30, and the welding quality between all junction boxes 30 and the leads 20a of the photovoltaic module 20 can be inspected simultaneously. For example, such as Figure 6 As shown, if three junction boxes 30 are installed on the photovoltaic module 20, then three detection bodies 200 are also set accordingly.

[0061] like Figures 3 to 5As shown, in some embodiments of this application, the detection body 200 further includes a power cylinder 250 disposed on the mounting base 210. The power output end of the power cylinder 250 is connected to the propelling member 230 and can drive the propelling member 230 to move along the Y-axis. The power cylinder 250 can drive the propelling member 230 to move along the Y-axis, which can improve the automation level of the device.

[0062] The power cylinder 250 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The number of power cylinders 250 can be set according to the number of the picking components 230. For example, if there are two picking components 230, there are also two power cylinders 250, with each picking component 230 corresponding to one power cylinder 250.

[0063] The power output end of the power cylinder 250 is connected to the force control motor 231 of the toggle member 230 via the connecting seat 251 (see...). Figure 4 To ensure that the power cylinder 250 can drive the toggle member 230 to move along the Y-axis, one of the connecting seat 251 and the mounting seat 210 is provided with a guide groove along the Y-axis, and the other is provided with a guide protrusion, which is accommodated in the guide groove.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the transfer module 100 includes a first transfer component 110, a second transfer component 120, and a third transfer component 130. The first transfer component 110 is used to drive the detection body 200 to move along the X-axis, the second transfer component 120 is used to drive the detection body 200 to move along the Y-axis, and the third transfer component 130 is used to drive the detection body 200 to move along the Z-axis.

[0065] See Figure 1 The first transfer assembly 110 may include a first power member 111, a first transmission member, and a first guide rail 112 along the X-axis. The first power member 111 can drive the second transfer assembly 120 to move along the first guide rail 112 via the first transmission member. This structure of the first transfer assembly 110 enables the detection body 200 to move automatically and oriented along the X-axis.

[0066] The first power component 111 can be a motor, and the first transmission component can be a belt drive mechanism or other transmission mechanism, such as a lead screw drive mechanism. The belt drive mechanism may include a driving pulley, a driven pulley, and a conveyor belt. The driving pulley is connected to the output shaft of the first power component 111, and the transmission belt is tensioned on the driving pulley and the driven pulley. The conveyor belt is located below the first guide rail 112, and the upper or lower half of the conveyor belt is connected to the second transfer assembly 120.

[0067] The first guide rail 112 can roll and guide the second transfer component 120. The steel ball rolls and circulates infinitely between the second transfer component 120 and the first guide rail 112, so that the second transfer component 120 can easily perform high-precision linear motion along the first guide rail 112 and reduce the coefficient of friction to one-fiftieth of that of conventional sliding guides, thus easily achieving very high positioning accuracy.

[0068] Two first guide rails 112 can be provided, with the two first guide rails 112 spaced apart along the Y-axis. The second transfer component 120 can slide along the two first guide rails 112, which also facilitates the sliding of the second transfer component 120. A first power component 111 is provided on the side of one of the first guide rails 112 and a first transmission component is provided below it.

[0069] See also Figure 1 The detection device 10 also includes a first cable chain mechanism 260, which is disposed at the movable connection between the first transfer component 110 and the second transfer component 120. The first cable chain mechanism 260 can be used to protect and manage cables, allowing the internal cables to move in an orderly manner when the equipment moves, preventing them from being damaged by bending, stretching, or abrasion, and ensuring line safety and stable equipment operation.

[0070] See also Figure 1 The second transfer assembly 120 may include a second power member 121, a second transmission member, and a second guide rail 122 along the Y-axis. The second power member 121 can drive the third transfer assembly 130 to move along the second guide rail 122 via the second transmission member. This structure of the second transfer assembly 120 enables the detection body 200 to move automatically and oriented along the Y-axis.

[0071] The second power component 121 has the same structure as the first power component 111, the second transmission component has the same structure as the first power transmission component, and the second guide rail 122 can also have the same structure as the first guide rail 112. Each end of the second guide rail 122 along the Y-axis has a slider, which can slide along its respective first guide rail 112.

[0072] See also Figure 1 The detection device 10 also includes a second drag chain mechanism 270, which is disposed at the movable connection between the third transfer component 130 and the second transfer component 120.

[0073] See also Figure 1 The third transfer assembly 130 may include a third power component 131, a third transmission component, and a third guide rail 132 along the Z-axis. The third power component 131 can drive the mounting base 210 to move along the third guide rail 132 via the third transmission component. This structure of the third transfer assembly 130 enables the detection body 200 to move automatically and oriented along the Z-axis.

[0074] The third power component 131 has the same structure as the first power component 111, the third transmission component has the same structure as the first transmission component, and the third guide rail 132 may also have the same structure as the first guide rail 112.

[0075] In order to allow the mounting base 210 of the detection body 200 to slide smoothly along the third guide rail 132, such as Figure 3 As shown, the mounting base 210 may include a sliding part 211, a connecting part 212 and a mounting part 213 connected in sequence. The sliding part 211 is slidably disposed on the third guide rail 132, and the mounting part 213 is used to mount the pressing member 220 and the propelling member 230.

[0076] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the detection device 10 also includes an image acquisition module 300, which is mounted on the mounting base 210 and can acquire the morphological information of the welded joint between the lead 20a and the junction box 30 after the lead 20a is propelled. When the lead 20a of the photovoltaic module 20 is propelled by the propeller 230, the image acquisition module 300 can acquire the morphological information of the welded joint between the lead 20a and the junction box 30. Based on this morphological information, it can be determined whether the connection between the lead 20a of the photovoltaic module 20 and the junction box 30 is reliable. For example, it can be determined whether there are cracks in the welded joint between the conductive terminal 30a of the junction box 30 and the lead 20a of the photovoltaic module 20.

[0077] The image acquisition module 300 can be a visual inspection mechanism, such as a camera.

[0078] In some other embodiments, the image acquisition module 300 can also acquire the morphological information of the welded part between the lead 20a and the junction box 30 after the photovoltaic module 20 is welded to the junction box 30, and can perform background comparison and record the defective parts.

[0079] In some embodiments of this application, the detection device 10 further includes a control module (not shown in the figures). The control module typically adopts a hierarchical architecture. The top layer is a monitoring and management system, which is responsible for monitoring the operating status of the entire device, scheduling tasks, and managing data. The middle layer is the core control unit, including a programmable logic controller (PLC) or an industrial personal computer (IPC), which receives instructions from the upper layer and converts them into specific control signals for the lower-level actuators. The bottom layer is the drive control of various actuators, such as various motors, cylinders, and solenoid valve controllers.

[0080] Solenoid valve controllers are installed in the gas passages of each cylinder to control the basic automated components of the fluid, adjusting the direction, flow rate, speed, and other parameters of the medium. Each gas passage is also equipped with a pressure regulating valve and a filter. The pressure regulating valve operates within a pressure range of 0 MPa to 0.9 MPa, with a limit not exceeding 1.0 MPa. It is primarily used to regulate the pressure of compressed air entering the gas passage, ensuring the system operates under stable pressure. The filter operates within a pressure range of 0 to 0.9 MPa, and its main function is to filter impurities, moisture, and oil from the compressed air, ensuring clean air entering the gas passage and preventing component wear and blockage. The minimum filtration accuracy is 5 μm.

[0081] On the other hand, one embodiment of this application also provides a photovoltaic module processing system, which includes a straightening device and a detection device 10 as described in any of the above claims. The straightening device is located upstream of the detection device 10 and can perform a straightening operation on the photovoltaic module 20 before detecting the welding quality of the photovoltaic module 20 lead 20a and the junction box 30.

[0082] The photovoltaic module 20 processing system provided in this application embodiment can automatically adjust the lead 20a of the photovoltaic module 20 after it is welded to the junction box 30. This allows for determination of reliable connection between the lead 20a and the junction box 30 by using a adjusting member 230. During the adjusting process, the pressing member 220 presses the junction box 30, preventing the parts of the photovoltaic module 20 located around the junction box 30 from being pulled and affecting the performance of the photovoltaic module 20. For example, it can prevent microcracks in the solar cells of the photovoltaic module 20 from occurring under external force. Therefore, this detection device 10 can automatically adjust the lead 20a of the photovoltaic module 20 without relying on manual adjustment. This improves efficiency, reduces costs, lowers the false negative rate, ensures product yield, and effectively controls the adjusting force to avoid damage to the lead 20a of the photovoltaic module 20, while also preventing damage to the solar cells of the photovoltaic module 20.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
