Description

[0002] After the production of photovoltaic modules is completed, they will undergo IV testing to test parameters such as power, opening voltage and short-circuit current of the photovoltaic modules.

[0003] To avoid the risk of electric shock during IV testing of PV modules, a connection fixture is typically used to connect the PV module to the IV test device. Specifically, the connection fixture is first installed on the PV module and electrically connected to the module. Once the PV module is positioned to the IV test device, the IV test device's cylinder lifts the probe until it makes electrical contact with the connection fixture, allowing the PV module to undergo IV testing.

[0004] However, the random contact between the probe and the connection tooling makes the contact force and contact position between the connection tooling and the probe on each photovoltaic module not fixed, resulting in different degrees of wear on each connection tooling, thus affecting the accuracy and stability of the IV test of the photovoltaic module.

[0030] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] See Figure 1 One embodiment of the present application provides photovoltaic module testing equipment, including an IV test device and a connection fixture 10 for photovoltaic module testing. Connection fixture 10 is used to connect the photovoltaic module under test to the IV test device, establishing an electrical path between the IV test device and the photovoltaic module under test, thereby enabling the IV test device to perform IV testing on the photovoltaic module under test.

[0032] The photovoltaic testing equipment further includes a conveyor device having an installation station and a testing station. The conveyor device is used to transport the photovoltaic modules to be tested through the installation station and the testing station. At the installation station, a connection tool 10 is installed on the photovoltaic module to be tested and electrically connected to the connection tool 10. An IV test device is located at the testing station and electrically connected to the connection tool 10 at the testing station.

[0033] During testing, the conveyor transports the photovoltaic module to the installation station. At the installation station, a person or a robotic arm installs the connection tool 10 on the frame of the photovoltaic module to be tested, and then electrically connects the connection tool 10 to the photovoltaic module to be tested. The conveyor then transports the photovoltaic module to the testing station. At the testing station, the IV test device is electrically connected to the connection tool 10, establishing an electrical path between the IV test device and the photovoltaic module to be tested, allowing the IV test device to perform IV testing on the photovoltaic module to be tested.

[0034] In one embodiment, see Figure 1 The IV test device includes a power fixture 20 and a drive mechanism. The power fixture 20 is connected to the output terminal of the drive mechanism. The power fixture 20 includes a base 21, a first power member 22, and a second power member 23. The first power member 22 and the second power member 23 are both located on the base 21. At the test station, the drive mechanism drives the power fixture 20 toward the connection fixture 10 until the power fixture 20 is electrically connected to the connection fixture 10, establishing an electrical path between the IV test device and the photovoltaic module under test. After the test is completed, the drive mechanism drives the power fixture 20 away from the connection fixture 10, separating the power fixture 20 from the connection fixture 10.

[0035] Optionally, the driving mechanism is a cylinder. Of course, in other embodiments, the driving mechanism may also be other devices, and is not limited thereto.

[0036] In one embodiment, see Figure 1 、 Figure 2 and Figure 3 The connection tool 10 includes a connection base 11, a positive connector, a negative connector, a positive conductive member 13, and a negative conductive member 14. The positive connector, the negative connector, the positive conductive member 13, and the negative conductive member 14 are disposed on the connection base 11. The positive connector is electrically connected to the positive conductive member 13 and is used to connect to the positive connecting wire of the photovoltaic module under test. The positive conductive member 13 is used to electrically connect to the first energizing member 22 of the IV test device. The negative connector is electrically connected to the negative conductive member 14 and is used to connect to the negative connecting wire of the photovoltaic module under test. The negative conductive member 14 is used to electrically connect to the second energizing member 23 of the IV test device.

[0037] In the installation station, the connecting tool 10 is installed on the frame of the photovoltaic module to be tested, and the positive connection wire of the photovoltaic module to be tested is connected with the positive connecting piece, and the negative connection wire is connected with the negative connecting piece. Then, the conveying device conveys the photovoltaic module to be tested with the connecting tool 10 to the test station. In the test station, the driving mechanism drives the power tool 20 to move towards the connecting tool 10 until the first power supply part 22 contacts with the positive conductive part 13 and the second power supply part 23 contacts with the negative conductive part 14, so that the electrical path is formed between the IV testing device and the photovoltaic module to be tested. Thus, the IV testing device can test the photovoltaic module to be tested.

[0038] In one embodiment, referring to Figure 1 The connecting tool 10 further comprises a magnetic attraction part 15. The magnetic attraction part 15 is used to be attached to the magnetic attraction matching part 24 of the IV testing device, so that the positive conductive part 13 contacts with the first power supply part 22 of the IV testing device and the negative conductive part 14 contacts with the second power supply part 23 of the IV testing device.

[0039] Optionally, the magnetic attraction part 15 is one of an electromagnet and a permanent magnet, and the magnetic attraction matching part 24 is one of an electromagnet and a permanent magnet.

[0040] In the test station, the driving mechanism drives the power tool 20 to move towards the connecting tool 10. When the power tool 20 approaches the connecting tool 10, the magnetic attraction part 15 is attached to the magnetic attraction matching part 24, so that the first power supply part 22 contacts with the positive conductive part 13 and the second power supply part 23 contacts with the negative conductive part 14. The power tool 20 and the connecting tool 10 are attached together by magnetic attraction, so as to realize the positioning of the power tool 20 and the connecting tool 10. In each test, the contact position and the contact force between the first power supply part 22 and the positive conductive part 13 and between the second power supply part 23 and the negative conductive part 14 remain consistent. The wear degree of each connecting tool 10 is basically consistent. Thus, the test error caused by the difference of the connecting tool 10 can be reduced, and the accuracy and stability of the test can be ensured.

[0041] In addition, the IV testing device has a position deviation in long-term operation. By using the magnetic attraction fixing mode, the contact position of the first power supply part 22 and the positive conductive part 13 and the contact position of the second power supply part 23 and the negative conductive part 14 can remain consistent. Thus, the test error caused by the deviation of the IV testing device can be avoided, and the accuracy and stability of the test can be ensured.

[0042] In addition, the production personnel do not need to check the contact condition between the first power supply part 22 and the positive conductive part 13 and between the second power supply part 23 and the negative conductive part 14, so as to save the production suspension time and improve the test yield.

[0043] In one embodiment, the positive electrode conductive member 13, the negative electrode conductive member 14, the first conductive member 22, and the second conductive member 23 are metal members with conductive functions. Optionally, the positive electrode conductive member 13, the negative electrode conductive member 14, the first conductive member 22, and the second conductive member 23 are made of metal copper, metal iron, etc., but are not limited thereto.

[0044] Further, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The positive conductive member 13, the negative conductive member 14, the first current member 22, and the second current member 23 have contact flat surfaces. Optionally, the positive conductive member 13, the negative conductive member 14, the first current member 22, and the second current member 23 are sheet-like, block-like, or plate-like structures of equal size and thickness. This arrangement increases the contact area between the positive conductive member 13 and the first current member 22, and between the negative conductive member 14 and the second current member 23, ensuring reliable contact between the positive conductive member 13 and the first current member 22, and between the negative conductive member 14 and the second current member 23.

[0045] In one embodiment, see Figure 1 The connecting tool 10 further includes a support member 16, and the connecting base 11 is mounted on the support member 16. The support member 16 is provided with a first connecting portion 164 and a second connecting portion 165 at both ends along its length, and the first connecting portion 164 and the second connecting portion 165 are respectively used to connect to opposite sides of the frame of the photovoltaic module to be tested.

[0046] At the installation station, the first connecting portion 164 of the support member 16 is connected to a specific position on one side of the frame of the photovoltaic module to be tested, and the second connecting portion 165 is connected to a specific position on the other side of the frame of the photovoltaic module to be tested, thereby installing the connection tool 10 on the photovoltaic module to be tested. By providing the support member 16, the support member 16 provides a mounting position for the connection base 11, facilitating the installation of the connection base 11.

[0047] In one embodiment, see Figure 1 The first connecting portion 164 is provided with a first snap-fitting groove, and the second connecting portion 165 is provided with a second snap-fitting groove. At the installation station, the first snap-fitting groove snaps into place with one side of the frame of the photovoltaic module under test, and the second snap-fitting groove snaps into place with the other side of the frame of the photovoltaic module under test, thereby detachably attaching the connecting tool 10 to the photovoltaic module under test and facilitating assembly and disassembly of the connecting tool 10.

[0048] Of course, in other embodiments, the first connection portion 164 may also abut against one side of the frame of the photovoltaic module to be tested, and the second connection portion 165 may abut against the other side of the frame of the photovoltaic module to be tested.

[0049] In one embodiment, see Figure 1 The support member 16 is a retractable structure. In this way, the length of the support member 16 can be adjusted according to the length of the photovoltaic module to be tested, so that the support member 16 is adapted to photovoltaic modules of different lengths to be tested. In this way, the connecting tool 10 can be installed on photovoltaic modules of different lengths to be tested.

[0050] Further, see Figure 1 The support member 16 includes a fixed rod 161, a first movable rod 162 and a second movable rod 163. The first movable rod 162 is movably mounted on one end of the fixed rod 161, and the second movable rod 163 is movably mounted on the other end of the fixed rod 161. The first movable rod 162 and the second movable rod 163 can move along the length direction of the fixed rod 161. The first connecting portion 164 is provided at the end of the first movable rod 162 away from the fixed rod 161, and the second connecting portion 165 is provided at the end of the second movable rod 163 away from the fixed rod 161. During installation, the first movable rod 162 and the second movable rod 163 can move relative to the fixed rod 161 to adjust the length of the support member 16 so that the support member 16 is adapted to photovoltaic modules to be tested of different lengths. In this way, the connecting tool 10 can be installed on photovoltaic modules to be tested of different lengths.

[0051] In one embodiment, see Figure 1 , there are two connecting seats 11, namely the first connecting seat 111 and the second connecting seat 112. The first connecting seat 111 is installed on the first movable rod 162, and the positive connector and the positive conductive member 13 are provided on the first connecting seat 111. The second connecting seat 112 is installed on the second movable rod 163, and the negative connector and the negative conductive member 14 are provided on the second connecting seat 112. At the installation station, the first movable rod 162 and the second movable rod 163 are adjusted along the length direction of the fixed rod 161 so that the distance between the first connecting seat 111 and the second connecting seat 112 is adapted to the distance between the first power-on member 22 and the second power-on member 23 to match different IV testing devices.

[0052] In one embodiment, see Figure 1 The base 21 is provided with two, namely a first base 211 and a second base 212. The first base 211 and the second base 212 are spaced apart, the first energizing member 22 is provided on the first base 211, and the second energizing member 23 is provided on the second base 212.

[0053] In one embodiment, see Figure 1 、 Figure 2 and Figure 3 The magnetic member 15 is provided with at least two, namely a first magnetic member 151 and a second magnetic member 152. The first magnetic member 151 is provided on the first connecting seat 111, and the second magnetic member 152 is provided on the second connecting seat 112.

[0054] Further, see Figure 1 、 Figure 4 and Figure 5 The magnetic fitting members 24 are provided with at least two, namely a first magnetic fitting member 241 and a second magnetic fitting member 242. The first magnetic fitting member 241 is provided on the first base 211, and the second magnetic fitting member 242 is provided on the second base 212.

[0055] At the test station, the driving mechanism drives the power-on tooling 20 to move toward the connecting tooling 10. When the power-on tooling 20 approaches the connecting tooling 10, the first magnetic component 151 is attracted and fitted with the first magnetic fitting component 241, so that the first power-on component 22 is in contact with the positive conductive component 13. At the same time, the second magnetic component 152 is attracted and fitted with the second magnetic fitting component 242, so that the second power-on component 23 is in contact with the negative conductive component 14. In this way, during each test, the contact position and contact force between the first power-on component 22 and the positive conductive component 13 and between the second power-on component 23 and the negative conductive component 14 remain consistent, and the degree of wear of each connecting tooling 10 is basically the same. This can reduce the test error caused by the differences in the connecting tooling 10 and ensure the accuracy and stability of the test.

[0056] In one embodiment, see Figure 1 The support member 16 further includes a first elastic member 166 and a second elastic member 167. One end of the first elastic member 166 is connected to the first movable rod 162, and the other end of the first elastic member 166 is connected to the first connecting portion 164. One end of the second elastic member 167 is connected to the second movable rod 163, and the other end of the second elastic member 167 is connected to the second connecting portion 165. The expansion and contraction direction of the first elastic member 166 and the second elastic member 167 is the same as the length direction of the support member 16. During installation, the first elastic member 166 and the second elastic member 167 expand and contract along the length direction of the support member 16 to adjust the length of the support member 16, so that the support member 16 can be quickly installed on the photovoltaic module to be tested.

[0057] In one embodiment, the IV testing device further includes a third elastic member and a fourth elastic member, and the third elastic member and the fourth elastic member are both disposed between the output end of the driving mechanism and the energized fixture 20 .

[0058] Specifically, one end of the third elastic member is connected to the output end of the drive mechanism, and the other end of the third elastic member is connected to the first base 211. One end of the fourth elastic member is connected to the output end of the drive mechanism, and the other end of the fourth elastic member is connected to the second base 212. In this way, the first base 211 and the second base 212 can move slightly in the vertical, horizontal, and leftward directions, ensuring that the magnetic member 15 and the magnetic mating member 24 can effectively adhere to each other, ensuring that the first energizing member 22 is in accurate contact with the positive conductive member 13, and that the second energizing member 23 is in accurate contact with the negative conductive member 14.

[0059] In this embodiment, the PV module IV test process is as follows:

[0060] S10. The conveying device conveys the photovoltaic module to be tested to the installation station. At the installation station, a person or a robotic arm connects the first connecting portion 164 and the second connecting portion 165 of the support member 16 to opposite sides of the frame of the photovoltaic module to be tested, and then connects the positive connecting wire of the photovoltaic module to the positive connecting member, and the negative connecting wire to the negative connecting member;

[0061] S20, when the conveying device conveys the photovoltaic module to be tested to the flipping station, the photovoltaic module to be tested is flipped at the flipping station so that the test surface of the photovoltaic module to be tested faces upward;

[0062] S30: The conveying device transports the photovoltaic module to be tested to the test station and activates the alignment module, which moves the photovoltaic module to the test fixed position. Then, the driving mechanism drives the power tool 20 upward. When the upward movement signal of the driving mechanism is triggered, the magnetic fitting 24 is energized after a delay of 0.5 seconds, causing the magnetic fitting 24 to generate a magnetic field. After the driving mechanism drives the power tool 20 to move to the specified height, the magnetic fitting 15 and the magnetic fitting 24 are attracted and attached, so that the first power member 22 is attached to the positive conductive member 13, and the second power member 23 is attached to the negative conductive member 14. An electrical path is formed between the IV test device and the photovoltaic module to be tested, and the IV test device initiates the test action.

[0063] S40: After the test is completed, the power supply of the power tool 20 of the IV test device is turned off, the magnetic force of the magnetic fitting 24 disappears, and after a delay of 0.5 seconds, the driving mechanism drives the power tool 20 to move downward;

[0064] S50: The conveying device continues to convey the photovoltaic module to be tested forward.
