Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a double-chip double-sided IV detection device which can flexibly adapt to the width of a battery chip. Background Art

[0002] Some solar cells are manufactured as a large panel and then need to be cut into two separate solar cells. When testing one by one, the efficiency is relatively low. It is more efficient to test two solar cells at the same time.

[0003] IV testing refers to testing the conversion efficiency of solar cells. It is necessary to test the current-voltage output of solar cells under the premise of fixed solar cell area and fixed light intensity for analysis. Its purpose is to help solar cells to classify performance intervals. Only when the performance of solar cells is close can the photovoltaic module with the best conversion efficiency be obtained.

[0004] Chinese patent CN213715411U discloses a double-cell cell testing device, which uses a rotating workbench to transport two cells to a test station on one side of the original conveyor line for testing to obtain the cell's electrical conversion efficiency. However, the conveyor line width of this device is fixed, and the position of the suction cup is also fixed. If cells of different widths are manufactured, cells with too large a width will be too close together during the conveying process, which may easily cause collision damage; if cells with too large a width are too far apart, when the light source range is fixed, the light may not cover the entire upper surface of the cell, or the electrical measurement may lead to inaccurate test results. Therefore, it cannot meet the needs of multiple cell widths.

[0005] Therefore, it is necessary to improve the detection equipment to solve the above problems. Summary of the invention

[0006] The main purpose of the utility model is to provide a double-cell double-sided IV detection device that can flexibly adapt to the width of the battery cell, and can first adjust the distance between the battery cells to a relatively close position to meet the electrical measurement requirements, thereby adapting to the synchronous testing of two battery cells with larger widths.

[0009] Four stations are evenly arranged around the rotary unit, and the four stations are a feeding station, a detection station, a discharging station and an empty station in sequence. The feeding station is close to the position adjustment unit, the discharging station is close to the discharging conveying unit, and the electrical measuring unit is arranged at the detection station;

[0010] The rotary unit includes a rotary mechanism that rotates 90° stepwise along the Z axis, a rotary frame driven by the rotary mechanism, and four workbenches uniformly distributed around a vertical axis on the edge of the rotary frame, each workbench is provided with two battery cell accommodating positions side by side, and the battery cell accommodating positions are connected vertically;

The first fixed suction and release mechanism and the first dynamic suction and release mechanism are arranged side by side along the Y direction.

[0013] Specifically, the first transport unit also includes a second lifting module, a first suction and release mechanism and a second suction and release mechanism. The second lifting module moves along the X direction under the drive of the first X-direction moving module. The first suction and release mechanism and the second suction and release mechanism are arranged side by side along the Y direction and are lifted and lowered synchronously under the drive of the second lifting module. The first suction and release mechanism and the second suction and release mechanism move the battery cells from the position adjustment unit to the workbench located at the feeding station.

[0014] Specifically, the second transport unit includes a second X-direction moving module, a second lifting module, a second fixed suction and release mechanism, a second dynamic suction and release mechanism and a second spacing adjustment cylinder.

[0015] Specifically, the feed conveying unit includes a pair of first conveying modules and a second conveying module sequentially arranged along the conveying direction, the first conveying module adjusts two battery cells to be arranged side by side, and the second conveying module adjusts two battery cells to be centered respectively.

[0018] Furthermore, the electrical measuring unit also includes an in-position sensor for detecting whether the workbench reaches the detection position, and the in-position sensor is located outside the moving path of the workbench; when the in-position sensor detects the workbench, the rotating mechanism stops working.

[0036] The utility model is further described in detail below in conjunction with specific embodiments.

[0037] Example:

[0038] like Figure 1 and Figure 2As shown, a double-cell double-sided IV testing device 1 that can flexibly adapt to the width of a cell comprises a feeding and conveying unit 11, a position adjustment unit 12, a first handling unit 13, a rotating unit 14, a second handling unit 15, an electric measuring unit 16 and a discharging and conveying unit 17; the feeding and conveying unit 11, the position adjustment unit 12, the rotating unit 14 and the discharging and conveying unit 17 are arranged in sequence along the X direction; four stations are evenly arranged around the rotating unit 14, and the four stations are a feeding station 14a, a testing station 14b, a discharging station 14c and an empty station 14d in sequence, the feeding station 14a is close to the position adjustment unit 12, the discharging station 14c is close to the discharging and conveying unit 17, and the electric measuring unit 16 is arranged at the testing station 14b. The first handling unit 13 first moves the cell 2 from the feeding and conveying unit 11 to the position adjustment unit 12, and then moves it to the workbench 143 located at the feeding station 14a. The second handling unit 15 can move the battery cell 2 from the workbench 143 located at the unloading station 14 c to the unloading conveying unit 17 .

[0039] like Figure 4 As shown, the rotating unit 14 includes a rotating mechanism 141 that rotates in 90° steps along the Z axis, a rotating frame 142 driven by the rotating mechanism 141, and four workbenches 143 evenly distributed around the vertical axis on the edge of the rotating frame 142, and each workbench 143 is provided with two battery cell accommodating positions 1431 side by side, and the battery cell accommodating positions 1431 are connected from top to bottom.

[0040] During electrical testing, the main parts of the upper and lower surfaces of the battery cell 2 must not be blocked, so the conventional conveying mechanism cannot be used here, which will interfere with the contact of the probe. Therefore, the two battery cells 2 must be supported by the workbench 143, and the middle position of the battery cell receiving position 1431 is empty, so as not to affect the action of the probe.

[0041] like Figure 3 As shown, the first transport unit 13 includes a first X-direction moving module 131, a first lifting module 132, a first fixed suction and release mechanism 133, a first dynamic suction and release mechanism 134 and a first spacing adjustment cylinder 135. The first X-direction moving module 131 drives the first lifting module 132 to move along the X-direction, the first lifting module 132 synchronously drives the first fixed suction and release mechanism 133 and the first spacing adjustment cylinder 135 to rise and fall, the first spacing adjustment cylinder 135 drives the first dynamic suction and release mechanism 134 to move along the Y-direction, and the first fixed suction and release mechanism 133 and the first dynamic suction and release mechanism 134 are arranged side by side along the Y-direction.

[0042] The first fixed suction and placement mechanism 133 and the first dynamic suction and placement mechanism 134 are not only used to complete the work of synchronously transferring the two battery cells 2 to the position adjustment unit 12, but also the first spacing adjustment cylinder 135 allows the Y-axis spacing distance of the first fixed suction and placement mechanism 133 and the first dynamic suction and placement mechanism 134 to be reduced after the battery cell 2 is sucked, so that the two battery cells 2 are pre-approached, and then the position is fine-tuned at the position adjustment unit 12, and then sent to the workbench 143, so that it can adapt to the range of light and detection when transferred to the detection station 14b, so that it can adapt to IV detection of battery cells 2 with a larger width.

[0043] like Figure 3 As shown, the first transport unit 13 also includes a second lifting module 136, a first suction and release mechanism 137 and a second suction and release mechanism 138. The second lifting module 136 moves along the X direction under the drive of the first X-direction moving module 131. The first suction and release mechanism 137 and the second suction and release mechanism 138 are arranged side by side along the Y direction and are synchronously lifted and lowered under the drive of the second lifting module 236. The first suction and release mechanism 137 and the second suction and release mechanism 138 move the battery cell 2 from the position adjustment unit 12 to the workbench 143 located at the feeding station 14a.

[0044] The first suction and placement mechanism 137 and the second suction and placement mechanism 138 are used to move the two battery cells 2 from the position adjustment unit 12 to the workbench 143 located at the feeding station 14a. In this way, the first fixed suction and placement mechanism 133 and the first dynamic suction and placement mechanism 134 only need to complete the task of moving the two battery cells 2 to the position adjustment unit 12. The two transfer actions are performed synchronously, making the work rhythm faster.

[0045] like Figure 5 As shown, the second transport unit 15 includes a second X-direction moving module 151, a second lifting module 152, a second fixed suction and release mechanism 153, a second dynamic suction and release mechanism 154 and a second spacing adjustment cylinder 155. The second X-direction moving module 151 drives the second lifting module 152 to move along the X-direction, the second lifting module 152 synchronously drives the second fixed suction and release mechanism 153 and the second spacing adjustment cylinder 155 to rise and fall, the second spacing adjustment cylinder 155 drives the second dynamic suction and release mechanism 154 to move along the Y-direction, and the second fixed suction and release mechanism 153 and the second dynamic suction and release mechanism 154 are arranged side by side along the Y-direction.

[0046] After the electrical measurement is completed, the distance between the two battery cells 2 must be restored to the normal distance during transportation, otherwise there will be a risk of collision. Therefore, after the second fixed suction and release mechanism 153 and the second dynamic suction and release mechanism 154 respectively adsorb the battery cells 2, the second spacing adjustment cylinder 155 is used to separate the two. In this way, the two parallel battery cells 2 are adapted to the transportation distance of the next workstation again.

[0047] like Figure 1As shown, the feed conveying unit 11 includes a pair of first conveying modules 111 and a second conveying module 112 arranged in sequence along the conveying direction, the first conveying module 111 adjusts the two battery cells 2 to be side by side, and the second conveying module 112 adjusts the two battery cells 2 to be centered respectively; the discharge conveying unit 17 includes a third conveying module 171, a pair of fourth conveying modules 172 and a fifth conveying module 173 arranged in sequence along the conveying direction, the fourth conveying module 172 adjusts the two battery cells 2 to be side by side, and the fifth conveying module 173 adjusts the two battery cells 2 to be centered respectively.

[0048] The use principle of the fourth conveyor module 172 is the same as that of the first conveyor module 111, and both are used to align the front and rear positions of the two battery cells 2. The use principle of the fifth conveyor module 173 is the same as that of the second conveyor module 112, and both are used to adjust the left and right directions of the battery cells 2. Because both detection and position positioning require pauses, the third conveyor module 171 is used as a buffer position.

[0049] like Figure 1 As shown, the electric measuring unit 16 includes a light source mechanism 161, an upper probe component 162 and a lower probe component 163 arranged from top to bottom at the detection station 14b, the light source mechanism 161 provides light downward, the upper probe component 162 is raised and lowered above the workbench 143, and the lower probe component 163 is raised and lowered below the workbench 143. The electric measuring unit 16 also includes a position sensor 164 for detecting whether the workbench 143 has reached the detection station 14b, and the position sensor 1628 is located outside the moving path of the workbench 143; when the position sensor 164 detects the workbench 143, the rotation mechanism 141 stops working.

[0050] When the cell 2 reaches the inspection station 14b, the supporting workbench 143 is also detected by the in-position sensor 164. At this time, the upper probe component 162 and the lower probe component 163 approach the cell 2 from the upper and lower positions respectively to form a test circuit. The light source mechanism 161 simultaneously illuminates the upper surfaces of the two cells 2, so that the IV test results can be obtained.

[0051] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
