[0002] In the photovoltaic field, IV testing (also known as IV measurement) is an important method for evaluating the performance of solar panels. It measures the current output of the cell at different voltages to obtain key parameters related to cell performance, such as open-circuit voltage (Voc), short-circuit current (Isc), fill factor (FF), and conversion efficiency (Eff).

[0003] Existing testing equipment performs IV testing on solar cells by manually operating a test probe, which results in slow testing speed and low testing accuracy. Summary of the Invention

Detailed Implementation

[0060] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0061] As a specific embodiment of the present invention, such as Figure 1 and Figure 2As shown, the battery cell IV testing device of this embodiment may include at least one pair of XYT adjustment modules 100 and a pin-connection testing module 200. Each XYT adjustment module 100 may include a base plate 110 and at least three adjustment components 120. The at least three adjustment components 120 are disposed on the base plate 110 along a first direction, and a top mounting plate 130 is rotatably connected to each of the at least three adjustment components 120. The adjustment components 120 at both ends of the base plate 110 drive corresponding portions of the top mounting plate 130 to move along a second direction, and the adjustment component 120 in the middle of the base plate 110 drives corresponding portions of the top mounting plate 130 to move along the first direction, which is perpendicular to the second direction. The pin-connection testing module 200 is disposed on the top mounting plate 130 of the at least one pair of XYT adjustment modules 100, and the at least one pair of XYT adjustment modules 100 drives the pin-connection testing module 200 to move and rotate in the horizontal plane along the first and second directions.

[0062] Specifically, the battery cell IV testing apparatus of the present invention is provided with at least a pair of adjustment modules 100, for example, a pair of adjustment modules 100 arranged opposite each other. Each adjustment module 100 is provided with a base plate 110, three adjustment components 120 arranged in a straight line on the base plate 110, and a top mounting plate 130 rotatably connected to the three adjustment components 120. Two adjustment components 120 are provided at both ends of the base plate 110, driving the corresponding connecting part of the top mounting plate 130 to move in a second direction (e.g., along the width direction of the base plate 110). The other adjustment component 120 is provided in the middle of the base plate 110, driving the corresponding connecting part of the top mounting plate 130 to move in a first direction (e.g., along the length direction of the base plate 110). The two ends of the pin test module 200 are provided on the top mounting plate 130 of the pair of adjustment modules 100. In other words, the adjustment components 120 at both ends of the base plate 110 enable the pin connection test module 200 to move along the width direction of the base plate 110 in the plane, while the adjustment component 120 in the middle of the base plate 110 enables the pin connection test module 200 to move along the length direction of the base plate 110 in the plane. This allows for convenient adjustment of the position of the pin connection test module 200 in the plane to match the position of the battery cell, effectively improving the detection efficiency and accuracy of the battery cell.

[0063] In addition, the top mounting plate 130 is rotatably connected to three adjustment components 120. When the adjustment components 120 at both ends of the base plate 110 drive the corresponding connecting parts of the top mounting plate 130 to move in opposite directions along the second direction, the top mounting plate 130 rotates around the middle adjustment component 120 as the center of rotation, and the two ends of the top mounting plate 130 rotate as driven by the adjustment components 120 at both ends of the base plate 110. That is to say, the battery cell IV testing device of the present invention can also drive the pin test module 200 to adjust the deflection angle by driving the rotation of the top mounting plate 130, further improving the positioning accuracy of the pin test module 200 for the battery cell.

[0064] Furthermore, the XYT adjustment module 100 of the present invention is arranged in a straight line, making the overall structure more elongated and facilitating a compact layout of existing IV testing devices, thus improving space utilization. Within a limited space, the positional adjustment of the needle test module 200 along the X and Y axes in the plane, as well as the adjustment of its deflection angle in the plane, can be achieved.

[0065] In some embodiments, such as Figure 3 As shown, the adjustment assembly 120 may include: a base plate 121, a first moving assembly 122, a second moving assembly 123, and a rotating assembly 124. The base plate 121 is disposed on the base plate 110. The first moving assembly 122 is disposed on the base plate 121. The second moving assembly 123 is disposed on the first moving assembly 122 perpendicular to it. The rotating assembly 124 is disposed on the second moving assembly 123 and is connected to the top mounting plate 130. The first moving assembly 122 drives the second moving assembly 123 to move linearly, and the second moving assembly 123 drives the rotating assembly 124 to move in a direction perpendicular to the second moving assembly 123.

[0066] In other words, the adjustment component 120 of this embodiment of the invention has a first moving component 122 on the substrate 121 and a second moving component 123 on the first moving component 122. The first moving component 122 drives the second moving component 123 to move in a straight line, and a rotating component 124 is provided on the second moving component 123. The second moving component 123 drives the rotating component 124 to move in a direction perpendicular to the movement of the second moving component 123. This enables the top mounting plate 130 connected to the rotating component 124 to move in the plane along the X-axis and Y-axis directions, which facilitates the positioning and adjustment of the pin test module 200 on the top mounting plate 130.

[0067] In some embodiments, such as Figure 2As shown, the first moving component 122 of the adjustment component 120 at both ends of the base plate 110 is arranged along the second direction, and the first moving component 122 of the adjustment component 120 in the middle of the base plate 110 is arranged along the first direction.

[0068] In other words, the adjustment components 120 at both ends of the base plate 110 are perpendicular to the adjustment component 120 in the middle, meaning the first moving components 122 of the adjustment components 120 at both ends are perpendicular to the first moving component 122 of the adjustment component 120 in the middle. As an example, the first moving components 122 of the adjustment components 120 at both ends are positioned along the width direction of the base plate 110, thereby driving the two ends of the connected top mounting plate 130 to move along the width direction of the base plate 110, thus causing the top mounting plate 130 as a whole to move along the width direction of the base plate 110. The first moving component 122 of the adjustment component 120 in the middle is positioned along the length direction of the base plate 110, thereby driving the middle portion of the connected top mounting plate 130 to move along the length direction of the base plate 110, thus causing the top mounting plate 130 as a whole to move along the length direction of the base plate 110.

[0069] It should be noted that, since the second moving component 123 of each adjustment component 120 is arranged perpendicular to the first moving component 122, the driving direction of the second moving component 123 is perpendicular to the driving direction of the first moving component 122. Therefore, the first moving components 122 of the adjustment components 120 at both ends and the second moving component 123 of the middle adjustment component 120 are arranged in the same direction. Furthermore, when the first moving components 122 of the adjustment components 120 at both ends drive the top mounting plate 130 to move along the width direction of the base plate 110, the middle portion of the top mounting plate 130 moves along the width direction of the base plate 110 under the action of the second moving component 123 of the middle adjustment component 120. Similarly, when the first moving component 122 of the middle adjustment component 120 drives the top mounting plate 130 to move along the length direction of the base plate 110, the two ends of the top mounting plate 130 move along the length direction of the base plate 110 under the action of the second moving components 123 of the adjustment components 120 at both ends.

[0070] In other words, by setting the adjustment components 120 on the base plate 110 to be perpendicular to each other, the top mounting plate 130 can be flexibly and cleverly adjusted in the X and Y axes of the plane.

[0071] Furthermore, when the first moving components 122 of the adjustment components 120 at both ends are driven in opposite directions, and with the coordinated action of the rotating components 124 at the top of each adjustment component 120, the top mounting plate 130 can be adjusted in the plane along the X-axis and Y-axis directions, while further rotation adjustment with the middle adjustment component as the rotation center can be achieved, which greatly improves the flexibility and accuracy of the position adjustment of the needle test module 200.

[0072] In some embodiments, such as Figure 3 As shown, the first moving component 122 may include at least one first guide rail 1221, a first sliding block 1222, and a first drive motor 1223. At least one first guide rail 1221 is disposed on the substrate 121. The first sliding block 1222 is slidably disposed on one of the first guide rails 1221. The first drive motor 1223 is disposed on one side of the substrate 121, and the output end of the first drive motor 1223 is connected to the first sliding block 1222 to drive the first sliding block 1222 to move linearly.

[0073] As an example, the first moving component 122 includes a first guide rail 1221 disposed on a substrate 121, a first sliding block 1222 slidably connected to the first guide rail 1221, and a first drive motor 1223 disposed on one side of the substrate 121, connected to the first sliding block 1222 to drive the first sliding block 1222 to slide on the first guide rail 1221. For example, the first drive motor 1223 is disposed on a motor base 1224 connected to one side of the substrate 121, and the first drive motor 1223 is connected to the first sliding block 1222 via a lead screw 1225. The first drive motor 1223 drives the lead screw 1225 to reverse direction to drive the first sliding block 1222 to move forward or backward.

[0074] In some embodiments, such as Figure 2 As shown, the second moving component 123 may include: at least one second guide rail 1231 and a second sliding block 1232. The at least one second guide rail 1231 is disposed perpendicular to the first guide rail 1221 on the first sliding block 1222. The second sliding block 1232 is slidably disposed on the at least one second guide rail 1231, and a rotary component 124 is disposed on the second sliding block 1232.

[0075] As an example, the second moving component 123 includes a second guide rail 1231 disposed on the first sliding block 1222. The second guide rail 1231 is perpendicular to the first guide rail 1221. A second sliding block 1232 is slidably connected to the second guide rail 1231, and a rotary component 124 is connected to the second sliding block 1232. Thus, the rotary component 124 can be adjusted in the plane along the X-axis and Y-axis directions via the first sliding block 1222 and the second sliding block 1232.

[0076] Furthermore, the adjustment component 120 of the present invention, by setting a first moving component 122 and a second moving component 123 that are perpendicular to each other, and using the first moving component 122 as the driving source, and by setting each adjustment component 120 perpendicular to each other on the base plate 110, can flexibly realize the adjustment of the position in the plane of the top mounting plate 130, which is simple, reliable and has low maintenance cost.

[0077] In some embodiments, the swivel assembly 124 may include a crossed roller bearing.

[0078] Specifically, the swivel assembly 124 of this embodiment of the invention may use, but is not limited to, crossed roller bearings to connect the top mounting plate 130 and the adjustment assembly 120.

[0079] In some embodiments, such as Figure 1 and Figure 4 As shown, the probe test module 200 may include: a mounting bracket 210, an upper probe array assembly 220, and a lower probe array assembly 230. The mounting bracket 210 is disposed on the top mounting plate 130 of at least one pair of XYT adjustment modules 100. The upper probe array assembly 220 and the lower probe array assembly 230 are disposed on the mounting bracket 210 in a way that allows them to move vertically relative to each other.

[0080] In other words, the probe test module 200 of the present invention includes a mounting bracket 210 disposed on a pair of XYT adjustment modules 100, and an upper probe array assembly 220 and a lower probe array assembly 230 disposed on the mounting bracket 210 and movable vertically relative to each other. On the one hand, the XYT adjustment module 100 can adjust the position of the mounting bracket 210 in the X and Y axes of the plane, as well as the rotation angle, to adapt to the position of the battery cell to be tested; on the other hand, by providing the upper probe array assembly 220 and the lower probe array assembly 230 that can move vertically relative to each other on the mounting bracket 210, it is convenient to match the size and model of the battery to be tested, wherein the number and arrangement of probes in the upper probe array assembly 220 and the lower probe array assembly 230 can be adjusted as needed.

[0081] In some embodiments, such as Figure 4 As shown, the mounting bracket 210 includes a pair of upright plates 211, which are respectively disposed on the top mounting plate 130 of at least one pair of XYT adjustment modules 100. The upper probe array assembly 220 and the lower probe array assembly 230 are disposed between the pair of upright plates 211 in a way that allows them to move up and down relative to each other.

[0082] As an example, the mounting bracket 210 includes a pair of upright plates 211, which are respectively mounted on the corresponding top mounting plate 110 for a pair of XYT adjustment modules 100. An upper probe array assembly 220 and a lower probe array assembly 230 are arranged in the space between the pair of upright plates 211 to leave space for the detection of the battery cells.

[0083] In some embodiments, the probe test module 200 further includes at least one pair of third guide rails 240, which are respectively disposed on the inner side surfaces of a pair of upright plates 211, and the upper probe array assembly 220 and the lower probe array assembly 230 are slidably disposed on the at least one pair of third guide rails 240.

[0084] In other words, a pair of third guide rails 240 are provided on the inner side of a pair of upright plates 211. The upper probe array assembly 220 and the lower probe array assembly 230 are slidably connected to the mounting bracket 210 through the third guide rails 240, making the upper probe array assembly 220 and the lower probe array assembly 230 more accurate and reliable when they are aligned.

[0085] In some embodiments, such as Figure 4 As shown, the probe testing module 200 may further include a first drive module 250 and a second drive module 260. The first drive module 250 and the second drive module 260 are mounted on the upright plate 211. The first drive module 250 is connected to the upper probe array assembly 220 to drive the upper probe array assembly 220 to move up and down, and the second drive module 260 is connected to the lower probe array assembly 230 to drive the lower probe array assembly 230 to move up and down.

[0086] As an example, both the first drive module 250 and the second drive module 260 can be mounted on the upright plate 211 on one side of the mounting bracket 210. The first drive module 250 and the second drive module 260 may include a drive motor, a lead screw, and a slider. The drive motor is connected to the lead screw and mounted on the upright plate 211. One end of the slider is movably connected to the lead screw, and the other end is connected to the upper probe array assembly 220 or the lower probe array assembly 230. The upright plate 211 has notches at the positions of the sliders of the first drive module 250 and the second drive module 260, and the sliders are movably disposed in the notches. The sliders are raised and lowered on the lead screw by driving the lead screw to rotate forward and backward by the drive motor, thereby reliably driving the upper probe array assembly 220 and the lower probe array assembly 230 to engage or disengage.

[0087] A second aspect of the present invention provides a battery cell IV testing machine, such as... Figure 5 As shown, it may include: a conveying module 300, a feeding robot 400, a vacuum turntable module 500, a cell IV testing device, a discharge module 600, and a discharge robot 700, wherein the cell IV testing device is the cell IV testing device of any embodiment of the first aspect described above.

[0088] Specifically, in this embodiment of the invention, the battery cell IV testing machine receives the battery cell 800 to be tested from the conveying module 300, and then the feeding robot 400 transfers the battery cell 800 from the conveying module 300 to the vacuum turntable module 500. After receiving the battery cell 800 at the first station of the vacuum turntable module 500, the battery cell 800 is first photographed and positioned, and then rotated and conveyed to the second station. The battery cell IV testing device at the second station performs IV testing on the battery cell 800. After the test is completed, the vacuum turntable module 500 rotates and conveys the battery cell 800 to the third station. The unloading robot 700 takes the battery cell 800 out from the third station of the vacuum turntable module 500 and transports it to the unloading module 600. After receiving the battery cell 800, the unloading module 600 conveys the battery cell 800 to the next machine.

[0089] It should be noted that the battery cell IV tester of the present invention has two conveyor lines, which can simultaneously transport and test two battery cells.

[0090] In some embodiments, such as Figure 5 As shown, the conveying module 300 may include a transition conveying unit 310, a positioning conveying unit 320, and a feeding conveying unit 330.

[0091] Specifically, the transition conveyor unit 310 receives a pair of solar cells 800 and uses a photoelectric sensor on the transition conveyor unit 310 to detect whether there are solar cells on the conveyor belt. The transition conveyor unit 310 conveys the received solar cells 800 to the positioning conveyor unit 320. The positioning conveyor unit 320 performs coarse positioning of the solar cells front and back using clamping and laser sensors to minimize the relative positional deviation of each pair of solar cells entering the vacuum turntable module 500. After coarse positioning, the positioning conveyor unit 320 then conveys the solar cells to the feeding conveyor unit 330.

[0092] It should be noted that after receiving a material signal from the feeding conveyor unit 330, the feeding robot 400 closes its upper gripper cylinder, making the distance between the two suction cups on the cylinder the same as the distance of the conveying section (i.e., the distance between the two suction cups on the feeding robot 400 is equal to the distance between a pair of battery cells). Simultaneously, the two lifting cylinders on the feeding robot 400 press down together, lowering the two suction cups to a suitable height for adsorbing the battery cells. After the feeding robot 400 adsorbs the pair of battery cells, its two lifting cylinders rise, and its lower cylinder, along with the upper mechanism, moves the pair of battery cells towards the vacuum turntable module 500. During this movement, the gripper cylinder opens, making the distance between the two suction cups on the cylinder the same as the required battery cell distance of the vacuum turntable module 500.

[0093] In some embodiments, such as Figure 5 and Figure 6As shown, the vacuum turntable module 500 may include: a fixed plate 510, a transmission adapter 520, four vacuum stage assemblies 530, and a positioning camera 540. The transmission adapter 520 is mounted on the fixed plate 510. The four vacuum stage assemblies 530 are sequentially connected to the four positions of the transmission adapter 520. The positioning camera 540 is positioned above the vacuum stage assemblies 530 near the feeding conveyor unit 330. The transmission adapter 520 drives the four vacuum stage assemblies 530 to rotate and shift.

[0094] Specifically, Figure 6 As shown, after the feeding robot 400 transports the battery cell pair to the first station (P1 position) of the vacuum turntable module 500, its suction cup releases the battery cell and returns to the feeding conveyor unit 330. After receiving the battery cell pair, the vacuum stage assembly 530 at the first station of the vacuum turntable module 500 opens its suction cup to adsorb the battery cell pair, and the positioning camera 540 above it takes pictures of the battery cell pair for precise positioning. After the positioning camera 540 has collected the data, the vacuum turntable module 500 rotates the vacuum stage assembly 530 carrying the battery cell at station P1 to the second station (P2 position). A pair of XYT adjustment modules 100 adjust the position and rotation angle parameters of the upper and lower probe array assemblies of the probe test module 200 in the X and Y axes according to the position data of the battery cell processed by the algorithm, so that the probe array assemblies are aligned with the grid lines of the battery cell. After the probe array assembly aligns with the grid lines of the solar cell, the probe assembly 200 drives the upper and lower probe array assemblies to press together, causing the solar cell located between the upper and lower probes to contact the probes. The tester then collects data from the solar cell. After the tester has collected the data, the upper and lower probe array assemblies of the probe assembly 200 open. The vacuum turntable module 500 rotates the vacuum stage assembly 530 at station P2 to the third station (position P3), and the vacuum stage assembly 530 stops adsorbing the solar cell. Finally, the unloading robot 700 removes the solar cell 800 from the third station and transports it to the unloading module 600.

[0095] In some embodiments, such as Figure 7 As shown, the vacuum stage assembly 530 may include: a support frame 531, a pair of vacuum stage gas path plates 532, and at least a pair of suction cup supports 533. One end of the support frame 531 is connected to the transmission adapter assembly 520. The pair of vacuum stage gas path plates 532 are respectively connected to the two sides of the other end of the support frame 531. The pair of suction cup supports 533 are respectively disposed on opposite sides of the pair of vacuum stage gas path plates 532, and the suction cup support 533 on a single vacuum stage gas path plate 532 is used to adsorb the battery cell 800.

[0096] In other words, the vacuum stage assembly 530 is connected to the transmission adapter assembly 520 via a support frame 531. Both sides of the support frame 531 are connected to the vacuum stage gas path plate 532 to provide gas passages to the suction cup bracket 533 of the vacuum stage gas path plate 532. The suction cup bracket 533 is equipped with multiple suction cups 534 for adsorbing the battery cells 800. Additionally, the vacuum stage gas path plate 532 is equipped with a gas path sealing gasket 535 to seal the gas path and ensure the reliability of the adsorption.
