[0002] Solar energy is an important energy for sustainable development of human society as it is widely distributed, inexhaustible and green. At present, solar energy is mainly used for photovoltaic power generation. The energy converter of solar photovoltaic power generation is a solar cell, also known as a photovoltaic module.
[0003] Before lamination, the photovoltaic module needs to be subjected to EL (electroluminescence) and IV tests to verify whether the module is in good condition before lamination. If the module is in good condition, it will be transferred to the next lamination process. If abnormalities are found, the module needs to be repaired and then subjected to EL and IV tests again. This process is repeated until the module is in good condition and then transferred to the next lamination process. Since the single-glass module has been laid with two layers of adhesive film, back plate and high-temperature cushion before entering the EL test, and the double-glass module has been laid with two layers of adhesive film, long strip, high-temperature cushion and corner protector, etc., when abnormalities are found in the module during the EL and IV tests, all the main materials and auxiliary materials on the back of the module need to be removed before the module can be repaired. This will cause great difficulty in production, affect the production rhythm and capacity release, and cause loss of product quality, material and labor after manual repair and re-laying of materials.
[0004] Therefore, it is necessary to design a testing device to solve the above technical problems. Content of the utility model

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0037] The embodiment of the present application provides a test device, which carries out pre-power-on test on EL and IV test of a photovoltaic module, and directly disassembles and repairs or abnormally processes the poor photovoltaic module without an encapsulation layer when the poor photovoltaic module needs to be repaired.
[0038] The test device provided by the embodiment will be described in detail below with reference to the accompanying drawings. Figures 1-4 As shown in the figure, the test device is applied after the photovoltaic module is stacked and welded, and is used for testing the photovoltaic module. The test device comprises a mounting component 10, a moving component 20 and a test clamping component 30. The mounting component 10 is arranged on one side of an assembly line and is used to play a mounting support role. The moving component 20 is arranged on the mounting component 10 and can move along a specific direction on the mounting component 10. The test clamping component 30 is provided with a terminal for connecting an external detection device, and the test clamping component 30 is assembled on the moving component 20 and can move synchronously with the moving component 20 to a specified position and clamp a module lead-out wire 40 to realize power-on detection.
[0039] The process flow of the photovoltaic module is generally one paving-pad-string welding-layout-welding-lamination-strip laying-second paving-backboard / back glass paving-high temperature pad and flat leading wire-corner installation-EL&IV testing-lamination. In the embodiment, the EL and IV testing process of the photovoltaic module is moved to the post-welding process, and the pre-positioned power-on testing can be realized by the testing device between the lamination and the second paving, and the defective module needs to be repaired or abnormally processed without encapsulation. Therefore, the main material and auxiliary material do not need to be repeatedly removed, and the problems of product quality loss, material and labor loss do not occur. Specifically, because the EL and IV testing needs to be powered on, the leading wire 40 of the module after lamination is in a vertical state, that is, a vertical leading wire. Correspondingly, the testing device in the embodiment is moved to the post-welding process, and the installation part 10 in the testing device is installed on one side of the assembly side, which is used to install and support the testing device. Then, the moving part 20 moves in a specific direction, that is, the direction of the vertical leading wire, so that the testing clamping part 30 clamps the vertical leading wire, and then realizes the power-on detection. Because the leading wire 40 of the module after the post-welding process is in a vertical state, the testing clamping part 30 can move from the side or the top to clamp the vertical leading wire (as shown in Figure 3 and 4 ), and the contact area with the vertical leading wire is increased by clamping; in the lamination process, the leading wire 40 of the module needs to be bent into a horizontal state, that is, a horizontal leading wire. In this working condition, the testing clamping part 30 can move downward from the top to contact the horizontal leading wire (as shown in Figure 5 ). Because the horizontal leading wire and the testing clamping part 30 have sufficient contact area, the power-on detection can be realized without clamping. Therefore, the testing device in the embodiment can meet the testing requirements of the vertical leading wire and the horizontal leading wire, and is more flexible to use, has a wide application scenario, and has high equipment utilization.
[0040] Please continue to refer to Figures 1-4As shown in the figure, in the present embodiment, it is to be noted that the mounting component 10 can include a first mounting plate 11 and a second mounting plate 12, the first mounting plate 11 is horizontally arranged, and screw holes for mounting can be formed on the first mounting plate 11, the mounting component 10 is fixed by using bolts and other components, the second mounting plate 12 is vertically arranged and the upper end is connected to the end of the first mounting plate 11, and the two are arranged in an L shape. When installing the test clamping component 30, the installation position can be adjusted according to the moving direction of clamping the vertical lead-out line. For example, when the test clamping component 30 needs to move from top to bottom to clamp the vertical lead-out line, the test clamping component 30 is installed below the first mounting plate 11 through the moving component 20, at this time the test clamping component 30 is in a vertical state and can then move from the top surface downward to clamp the vertical lead-out line; when the test clamping component 30 needs to clamp the vertical lead-out line from the side, such as from left to right or from right to left, it is only necessary to adjust the installation position of the test clamping component 30, that is, the test clamping component 30 is installed on the side of the second mounting plate 12 through the moving component 20, at this time the test clamping component 30 is in a horizontal state and can then move from the side to clamp the vertical lead-out line. How to set it specifically is not limited in the present embodiment.
[0041] Please refer to Figure 1 、 Figure 2 As shown in the figure, in the present embodiment, it is to be noted that the test device further includes a detection camera component 50 and a control component 60, both of which are arranged on the mounting component 10, and the control component 60 is electrically connected to the detection camera component 50 and the moving component 20. The detection camera component 50 is used to take pictures to identify the position of the component lead-out line 40 and send the identification signal to the control component 60; the control component 60 is used to receive the identification signal of the detection camera component 50 and control the moving component 20 to move with the test clamping component 30 to the position of the component lead-out line 40.
[0042] Specifically, the detection camera component 50 and the control component 60 are both mounted on the second mounting plate 12 of the mounting component 10, and are arranged on both sides of the second mounting plate 12, the detection camera component 50 is used to take pictures to identify the position of the component lead-out line 40 (such as Figure 3 、 Figure 4 and Figure 5The detection camera component 50 can be a detection camera, a lens of the detection camera is directed to the position of the component outgoing line 40, and the detection camera component 50 can be used to take a picture of the component outgoing line 40 to identify the position of the component outgoing line 40, so as to facilitate the clamping operation of the test clamping component 30. The control component 60 is used to receive the identification signal of the detection camera component 50, and control the movement component 20 to move to the position of the component outgoing line 40. After the detection camera component 50 takes a picture of the position of the component outgoing line 40, the control component 60 receives the identification signal, and then controls the movement component 20 to move to the position of the component outgoing line 40 with the test clamping component 30 until the test clamping component 30 clamps or abuts against the component outgoing line 40. Preferably, the control component 60 can be an execution controller with a control function, which is a commonly used controller in the art, such as a PLC controller.
[0043] Please continue to refer to Figure 1 、 Figure 2 In this embodiment, it should be further pointed out that the movement component 20 includes a fixed driving part 21, a movement reciprocating part 22, and a transmission part 23. The transmission part 23 is connected between the fixed driving part 21 and the movement reciprocating part 22. The fixed driving part 21 is arranged on the first mounting plate 11 of the mounting component 10 and is electrically connected to the control component 60. The fixed driving part 21 is in transmission connection with the transmission part 23. The transmission part 23 is connected with the movement reciprocating part 22. The fixed driving part 21 drives the movement reciprocating part 22 to move along a specific direction, such as from the top surface downward or from the side surface, through the transmission part 23. The test clamping component 30 is installed on the movement reciprocating part 22 and moves along a specific direction, such as from the top surface downward or from the side surface, with the test clamping component 30 under the action of the transmission part 23, so as to clamp or abut against the component outgoing line 40.
[0044] In one example, the fixed driving part 21 includes a driving motor arranged on the mounting component 10 and electrically connected to the control component 60. Specifically, the driving motor is installed on the lower surface of the first mounting plate 11 of the mounting component 10, and the output shaft of the driving motor is arranged vertically downward. The driving motor is electrically connected to the control component 60, so that the control component 60 can control the start or stop of the driving motor.
[0045] The transmission part 23 mainly converts the rotating motion of the output shaft of the driving motor into the linear motion of the moving reciprocating part 22. The transmission part 23 comprises a reciprocating screw 231 connected to the driving motor and a screw block 232 cooperating with the reciprocating screw 231 and being limited to move along the axial direction of the reciprocating screw 231. Specifically, the reciprocating screw 231 is coaxially arranged with the output shaft of the driving motor, the upper end of the reciprocating screw 231 is connected to the output shaft of the driving motor, and the lower end of the reciprocating screw 231 is rotatably connected to the frame 70 fixed on the side surface of the second mounting plate 12, mainly serving to support the reciprocating screw 231. The screw block 232 is used in cooperation with the reciprocating screw 231, and the screw block 232 is limited to move along the axial direction of the reciprocating screw 231 during the self-rotation of the reciprocating screw 231. This part is a relatively mature technology in the art, and will not be described in detail here.
[0046] The moving reciprocating part 22 is arranged on the screw block 232, and the moving reciprocating part 22 can be arranged as a moving plate. The moving plate is vertically arranged, the upper end of the moving plate is fixed on the screw block 232, and the lower end of the moving plate is used to mount the test clamping component 30. The vertically arranged moving plate can increase the stroke of the test clamping component 30, avoiding the situation that the reciprocating screw 231 is not long enough to clamp the component lead-out wire 40.
[0047] Therefore, as described above, the driving motor drives the reciprocating screw 231 to rotate, the reciprocating screw 231 rotates while the screw block 232 moves along the axial direction of the reciprocating screw 231, and the test clamping component 30 moves along with the moving plate during the movement of the screw block 232.
[0048] Of course, the transmission part 23 in the embodiment is not limited to the cooperation of the reciprocating screw 231 and the screw block 232, and other transmission structures can also be used, as long as the structure can convert the rotating motion of the output shaft of the driving motor into the linear motion of the moving reciprocating part 22. The embodiment is not specifically limited.
[0049] Please refer to Figure 1 , Figure 6 and Figure 7As shown, in the embodiment, it is also to be noted that the test clamping component 30 comprises a bottom row seat 31 and a detection probe clamp group 32, the bottom row seat 31 is fixed on the moving reciprocating part 22 of the moving component 20, i.e. the moving plate, and the bottom row seat 31 is horizontally arranged and perpendicular to the moving plate. The detection probe clamp group 32 is arranged on the bottom row seat 31, and the detection probe clamp group 32 is arranged in one group or multiple groups, when arranged in multiple groups, the multiple detection probe clamp groups 32 are arranged at equal intervals on the bottom row seat 31, and are arranged along the arrangement direction of the component lead-out line 40, and then when clamped from top to bottom, one detection probe clamp group 32 corresponds to clamping one component lead-out line 40.
[0050] In some embodiments, each detection probe clamp group 32 comprises two oppositely and interval arranged detection probe clamp arms 321, and the two detection probe clamp arms 321 can jointly clamp the component lead-out line 40. The inner end of the detection probe clamp arm 321, i.e. the end close to the bottom row seat 31, is connected with an elastic member 322 between the detection probe clamp arm 321 and the bottom row seat 31, one end of the elastic member 322 is connected with the inner end of the detection probe clamp arm 321, and the other end is connected to the bottom row seat 31, and preferably, a connecting block 323 is fixed on the bottom row seat 31, and the two elastic members 322 in each detection probe clamp group 32 are connected to the connecting block 323. Through the arrangement of the elastic member 322, when the two detection probe clamp arms 321 move to clamp the component lead-out line 40, after the outer ends of the two detection probe clamp arms 321 contact the component lead-out line 40, the two detection probe clamp arms 321 continue to press down, and the opposite component lead-out line 40 also exerts a reaction force on the two detection probe clamp arms 321, and under the continuous extrusion of the component lead-out line 40 and the action of the elastic member 322, the two detection probe clamp arms 321 are extruded apart, and after the component lead-out line 40 enters between the two detection probe clamp arms 321, the elastic member 322 rebounds to reset the two detection probe clamp arms 321 to each other to clamp the component lead-out line 40, thereby improving the contact effect. In addition, the component lead-out line 40 has glass on the upper and lower sides in the horizontal state, which has a certain supporting effect, and although the component lead-out line 40 is subjected to force during extrusion, the force will not be transmitted to the battery string, thereby not causing risks to the battery string.
[0051] In some embodiments, a gap is arranged between the two elastic members 322 in each detection probe clamp group 32, the elastic members 322 are arranged in an arc structure, the two elastic members 322 are oppositely arranged in an arch position, and the opening of the arc structure faces outward. In this way, when the assembly lead-out line 40 extrudes the outer ends of the two detection probe clamp arms 321, the two elastic members 322 are facilitated to open in a direction away from each other, and when the assembly lead-out line 40 is located between the two detection probe clamp arms 321, the two elastic members 322 are facilitated to close in a direction close to each other. In addition, when the assembly lead-out line 40 is in a transverse lead-out line state, since the detection probe clamp arm 321 and the transverse lead-out line adopt a contact type, the contact type needs to ensure sufficient contact area and extrusion force to ensure the contact effect, so that the extrusion can be achieved by pressing the detection probe clamp arm 321. Since the elastic member 322 is provided, the elastic member 322 can also play a certain buffering role to avoid excessive extrusion force on the transverse lead-out line and reduce the risk of the assembly. Preferably, the elastic member 322 can be provided as a spring piece.
[0052] In some embodiments, the inner side of the end of the two detection probe clamp arms 321 in each detection probe clamp group 32 away from the elastic member 322 is arranged as a guide surface 324, and the opening distance between the opposite two guide surfaces 324 in each detection probe clamp group 32 gradually decreases from the outside to the inside. Through the arrangement of the guide surface 324, the detection probe clamp arm 321 can play a guiding role when clamping the assembly lead-out line 40. The assembly lead-out line 40 can be smoothly guided into the two detection probe clamp arms 321, and when the assembly lead-out line 40 is in a vertical lead-out line state, the vertical angle of the vertical lead-out line may be slightly deviated. At this time, the two detection probe clamp arms 321 may have errors when moving downward to clamp the vertical lead-out line. In the present embodiment, the slightly deviated vertical lead-out line can be guided between the two detection probe clamp arms 321 through the arrangement of the guide surface 324.
[0053] In some embodiments, the inner wall side of the two detection probe clamp arms 321 in each detection probe clamp group 32 is respectively provided with a clamping groove 325, and the two clamping grooves 325 are correspondingly arranged. Preferably, the clamping groove 325 is a circular arc groove. For some cylindrical lead-out lines, the clamping groove 325 can be used to achieve clamping, thereby improving the stability of clamping. For sheet-shaped lead-out lines, the clamping groove 325 is not used, but the inner wall side of the two detection probe clamp arms 321 is used for clamping.
[0054] The implementation principle of the embodiment is: by moving the EL and IV tests of the photovoltaic module to after the lamination process, the EL and IV tests can be performed between the lamination and the second paving, since the EL and IV tests require power supply, the lead-out wire 40 of the module after lamination is in a vertical state, i.e., a vertical lead-out wire, the position of the vertical lead-out wire is identified by the detection and camera component 50, after the control component 60 receives the identification signal, the control component 60 controls the movement component 20 to move the test clamping component 30 to the position of the vertical lead-out wire, after the outer end guide surface 324 of the two detection probe clamping arms 321 in the test clamping component 30 contacts the vertical lead-out wire, the two detection probe clamping arms 321 are pushed apart, under the action of the elastic member 322, the two detection probe clamping arms 321 are pushed apart, until the vertical lead-out wire is located between the two detection probe clamping arms 321, the elastic member 322 rebounds to clamp the vertical lead-out wire between the two detection probe clamping arms 321 to improve the contact effect, and then a second sequence of power supply is performed until the three-sequence power supply test is completed; by implementing the pre-power supply test, when a defective module is found to be in need of repair, the module can be directly disassembled for repair or abnormal processing without the need for repeated disassembly of the main material and auxiliary material as in the prior art.
[0055] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present disclosure.
[0056] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
