[0045] To better understand the embodiments of this application, the following is combined with... Figures 1 to 11 The embodiments of this application will be described in detail.

[0046] like Figures 1 to 11 As shown, this application provides a solar cell testing device 1, including a support assembly 11, a probe assembly 12, a pressure plate assembly 13, and a frame 14. The support assembly 11 supports the solar cell 2; the probe assembly 12 is disposed below the support assembly 11 along a first direction X, and includes a probe module 121, which includes a plurality of probes 1211 spaced apart along a second direction Y; the pressure plate assembly 13 is disposed above the support assembly 11 along the first direction X, and is made of glass. A groove 131 is provided on the side of the pressure plate assembly 13 facing away from the support assembly 11 to reinforce the pressure plate assembly 13; at least two of the support assembly 11, probe assembly 12, and pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X.

[0047] The solar cell testing device 1 is a component used to measure the electrical characteristics, conversion efficiency, stability and other properties of the solar cell 2. The measurement results of the solar cell testing device 1 can be used to evaluate the quality of the produced solar cell 2 and ensure the efficiency and reliability of the solar cell 2 in practical applications.

[0048] The support component 11 is a component used to support the solar cell 2. Specifically, the support component 11 can be a clamping device such as a gripper, or an adsorption device such as a magnetic adsorption component or a vacuum adsorption component. This application embodiment does not limit this. By setting up the support component 11, a stable support can be provided for the solar cell 2 during the testing process, ensuring that the solar cell 2 remains flat and relatively fixed during the test, avoiding measurement errors caused by the shaking or positional displacement of the solar cell 2, thereby ensuring the accuracy and reliability of the test results of the solar cell 2.

[0049] The probe assembly 12 is disposed below the support assembly 11 along the first direction X. When the two are close to each other, the probes 1211 of the probe assembly 12 can contact the grid lines of the solar cell 2, thereby realizing the performance testing of the solar cell 2. The probe assembly 12 includes probe modules 121. Specifically, the probe assembly 12 may include only one probe module 121 or multiple probe modules 121. This embodiment of the application does not limit this. It should be noted that the number of probe modules 121 should be greater than or equal to the number of grid lines on the solar cell 2.

[0050] The probe module 121 includes a plurality of probes 1211 spaced apart along the second direction Y. The number and spacing of the probes 1211 are designed according to the number and spacing of the grid lines of the solar cell 2. When the probe assembly 12 and the carrier assembly 11 approach each other, the probes 1211 contact the grid lines on the solar cell 2, thereby realizing the performance testing of the solar cell 2.

[0051] The pressure plate assembly 13 is disposed on the upper side of the support assembly 11 along the first direction X, that is, the pressure plate assembly 13 and the probe assembly 12 are respectively disposed on both sides of the support assembly 11 along the first direction X. In this way, during the testing of the solar cell 2, when the probe 1211 of the probe assembly 12 contacts the solar cell 2, the pressure plate assembly 13 is abutted against the end of the solar cell 2 away from the probe assembly 12, so as to restrict the movement of the solar cell 2 along the first direction X, ensure effective contact between the probe 1211 and the solar cell 2, and thus ensure the testing accuracy and reliability of the solar cell 2.

[0052] The pressure plate assembly 13 is made of glass. In this way, during the test, the glass material allows light to penetrate the pressure plate assembly 13 and act on the surface of the solar cell 2, which can simulate the lighting environment of the solar cell 2 in actual use scenarios, improve the detection accuracy of the solar cell 2, and ensure that the test results are closer to the actual use of the solar cell 2.

[0053] A groove 131 is provided on the side of the pressure plate assembly 13 away from the support assembly 11, that is, the groove 131 is provided on the upper surface of the pressure plate assembly 13. During the test, it will not affect the limiting effect of the pressure plate assembly 13 on the solar cell 2. The groove 131 can be a regular shape such as a circle or square, or it can be an irregular shape composed of straight lines and / or curves. This application embodiment does not limit this. By providing the groove 131, the stress generated by the pressure plate assembly 13 under force can be effectively dispersed, so that the stress is more evenly distributed on the pressure plate assembly 13, thereby improving the compressive strength and impact resistance of the pressure plate assembly 13.

[0054] At least two of the support assembly 11, probe assembly 12, and pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X, specifically including the following two schemes:

[0055] Option 1: The carrier assembly 11, probe assembly 12 and pressure plate assembly 13 are all movably mounted on the frame 14 along the first direction X. The contact and separation of the probe 1211 with the solar cell 2 are achieved by adjusting the relative positions of the three components in the first direction X, thereby enabling the testing of the solar cell 2.

[0056] Option 2: Any two of the carrier assembly 11, probe assembly 12, and pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X. Specifically, in some embodiments, the carrier assembly 11 is fixedly disposed on the frame 14, while the probe assembly 12 and pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X. The solar cell 2 is tested by moving the probe assembly 12 closer to or further away from the carrier assembly 11. In other embodiments, the probe assembly 12 is fixedly disposed on the frame 14, while the carrier assembly 11 and pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X. The solar cell 2 is tested by moving the carrier assembly 11 closer to or further away from the probe assembly 12. Similarly, in still other embodiments, the pressure plate assembly 13 is fixedly disposed on the frame 14, while the carrier assembly 11 and probe assembly 12 are movably disposed on the frame 14 along the first direction X. The solar cell 2 is tested by moving the carrier assembly 11 closer to or further away from the pressure plate assembly 13.

[0057] It should be noted that the relative movement of the bearing assembly 11, probe assembly 12, and pressure plate assembly 13 with the frame 14 can be achieved by a guide rail slider mechanism or a lead screw mechanism, and this application embodiment does not limit this.

[0058] By providing a groove 131 on the side of the pressure plate assembly 13 away from the support assembly 11, when at least two of the support assembly 11, probe assembly 12 and pressure plate assembly 13 move relative to the frame 14 along the first direction X and the probe 1211 comes into contact with the solar cell 2, the groove 131 can effectively disperse and absorb the external force acting on the pressure plate assembly 13, thereby enhancing the strength of the pressure plate assembly 13 and preventing the pressure plate assembly 13 from breaking and affecting the production efficiency and quality of the solar cell 2.

[0059] like Figure 1 , 2 As shown in Figure 5, in some embodiments, the solar cell testing device 1 further includes a camera 15 disposed on the upper side of the pressure plate assembly 13 for calibrating the positions of the solar cell 2 and the probe 1211.

[0060] The camera 15 is positioned above the pressure plate assembly 13, allowing it to view the solar cell 2 and probe 1211 from above, thus obtaining a clear and comprehensive field of view. Meanwhile, the pressure plate assembly 13 is made of glass, ensuring that light can pass through smoothly while allowing the camera 15 to clearly capture the surface of the solar cell 2 and the position of the probe 1211.

[0061] By setting up the camera 15, the position of the grid line of the solar cell 2 and the tip position of the probe 1211 can be captured. Then, the precise distance and relative position relationship between the two can be calculated to ensure that the probe 1211 is precisely aligned with the grid line of the solar cell 2, thereby improving the testing accuracy of the solar cell testing device 1.

[0062] like Figure 1 , 4 As shown in Figures 5 and 9, in some embodiments, the groove 131 is an arched groove 131 extending along the second direction Y, and the edge of the arched groove 131 along the first direction X coincides with the projection of the probe 1211.

[0063] The groove 131 is an arched groove 131 extending along the second direction Y. When subjected to force, the arched structure of the groove 131 can disperse and transfer the external force to other adjacent parts, so that the stress of the pressure plate assembly 13 can be evenly distributed along the arched structure when under pressure. This allows the pressure plate assembly 13 to effectively disperse and bear the pressure, avoid damage caused by stress concentration, enhance the stability and load-bearing capacity of the pressure plate assembly 13, and extend the service life of the pressure plate assembly 13.

[0064] The edge of the arched groove 131 along the first direction X coincides with the projection of the probe 1211, that is, the edge of the arched groove 131 and the probe 1211 are directly opposite each other in the first direction X. In this way, when the camera 15 performs photo calibration, it can be ensured that the edge and the vertex of the probe 1211 coincide on a straight line, which can avoid the vertex of the probe 1211 being distributed around the edge, thus increasing interference and affecting the calibration accuracy of the camera 15.

[0065] like Figure 3 , 4 As shown in Figure 8, in some embodiments, the pressure plate assembly 13 includes a plurality of arched grooves 131 arranged adjacent to each other along the third direction Z, and the probe assembly 12 includes a plurality of probe modules 121 spaced apart along the third direction Z, and the spacing distance d1 of the probe modules 121 along the third direction Z and the width d2 of the arched grooves 131 along the third direction Z satisfy an integer multiple relationship.

[0066] The pressure plate assembly 13 includes a plurality of arched grooves 131 arranged adjacent to each other along the third direction Z. By providing a plurality of arched grooves 131, the stress generated by the pressure plate assembly 13 under force can be further dispersed, thereby further improving the strength of the pressure plate assembly 13. In addition, the adjacent arrangement of the arched grooves 131 allows two adjacent arched grooves 131 to form a common edge, which can prevent an excessive number of edges from affecting the calibration accuracy of the camera 15.

[0067] The probe assembly 12 includes a plurality of probe modules 121 spaced apart along the third direction Z. That is, the spacing distribution direction of the probe modules 121 is consistent with the extension direction of the arched groove 131. In this way, all probes 1211 of the probe module 121 and the edges of the arched groove 131 can be aligned in the first direction X, further improving the calibration accuracy of the camera 15.

[0068] The spacing d1 of the probe modules 121 along the third direction Z and the width d2 of the arched groove 131 along the third direction Z satisfy an integer multiple relationship. Specifically, when the spacing d1 of the probe modules 121 along the third direction Z is greater than or equal to the width d2 of the arched groove 131 along the third direction Z, d1 = n d2, where n is a positive integer; and when the spacing d1 of the probe modules 121 along the third direction Z is less than or equal to the width d2 of the arched groove 131 along the third direction Z, d2 = n d1, where n is a positive integer. In this way, it can be ensured that the probes 1211 of all probe modules 121 coincide with the edges of the arched groove 131 in the first direction X, improving the calibration accuracy of the camera 15.

[0069] like Figures 9 to 11As shown, in some embodiments, the pressure plate assembly 13 further includes an adsorption element 132 and an air delivery channel 133. The adsorption element 132 is disposed on the surface of the pressure plate assembly 13 near the support component 11. One end of the air delivery channel 133 is connected to the adsorption element 132, and the other end is connected to the side of the pressure plate assembly 13.

[0070] The adsorption element 132 is disposed on the surface of the pressure plate assembly 13 near the support assembly 11. Specifically, the adsorption element 132 can be a negative pressure suction cup or a Bernoulli suction cup, and this embodiment does not limit this. By disposing of the adsorption element 132 on the surface of the pressure plate assembly 13 near the support assembly 11, the adsorption element 132 can adsorb and fix the solar cell 2 during the testing process, ensuring that the solar cell 2 will not shift or shake during the testing process, reducing measurement errors caused by the movement of the solar cell 2, thereby improving the testing accuracy and reliability of the solar cell testing device 1.

[0071] One end of the gas delivery channel 133 is connected to the adsorption element 132, and the other end is connected to the side of the pressure plate assembly 13. This allows gas to be delivered to the adsorption element 132 through the gas delivery channel 131, thereby enabling the adsorption function of the adsorption element 132. Furthermore, connecting the other end of the gas delivery channel 131 to the side of the pressure plate assembly 13 prevents gas delivery components such as pipes from being placed on top of the pressure plate assembly 13 and obstructing the field of view of the camera 15, thus affecting the calibration accuracy of the camera 15. It should be noted that the cross-section of the gas delivery channel 133 can be a regular shape such as square or circle, or an irregular shape composed of straight lines and / or curves; this embodiment does not impose any limitations on this.

[0072] like Figure 11 As shown, in some embodiments, the adsorption element 132 is a Bernoulli suction cup.

[0073] Specifically, high-speed gas is delivered to the adsorption element 132 through the gas delivery channel 131. The high-speed airflow generates a low-pressure area on the surface of the Bernoulli suction cup, thereby generating an adsorption force to adsorb the solar cell 2 onto one side of the pressure plate assembly 13.

[0074] By setting the adsorption element 132 as a Bernoulli suction cup, on the one hand, the Bernoulli suction cup generates adsorption force through the low-pressure area, which will not generate local high-pressure points on the surface of the solar cell 2, thereby avoiding damage to the solar cell 2 caused by excessive local pressure; on the other hand, the Bernoulli suction cup is a non-contact adsorption method, which can avoid contamination or damage to the surface of the solar cell 2 due to contact.

[0075] like Figure 1 , 4As shown in Figures 5 and 7, in some embodiments, the support assembly 11 is rotatably disposed on the frame 14. The support assembly 11 includes a plurality of support members 111 and a holding member 112 disposed on the support member 111, and the plurality of support members 111 are arranged in an array on a circumference with the rotation center of the support assembly 11 and the frame 14 as the center.

[0076] The load-bearing component 11 is rotatably mounted on the frame 14. Specifically, the rotatable arrangement between the load-bearing component 11 and the frame 14 can be achieved by a rotating shaft, bearing, or rotating support. This application embodiment does not limit this.

[0077] The carrier assembly 11 includes multiple carrier members 111 and holding members 112 disposed on the carrier members 111. The holding member 112 is a component used to hold the solar cell 2. Specifically, the holding member 112 can be a clamping component such as a gripper, or a magnetic adsorption component, suction cup, or other attachment component; this embodiment does not limit this. By setting multiple carrier members 111, the solar cell 2 on the previous carrier member 111 can be tested while the solar cell 2 on the next carrier member 111 is being placed or removed. This allows the testing and loading / unloading processes of the solar cell 2 to be performed in parallel, thereby reducing equipment downtime and improving the testing efficiency of the solar cell testing device 1.

[0078] Multiple carriers 111 are arrayed on a circle with the rotation center of the carrier assembly 11 and the frame 14 as the center. In other words, multiple carriers 111 are arrayed on the circumference, and the center of the circumference coincides with the rotation center of the carrier assembly 11 and the frame 14. In this way, the carrier assembly 11 can sequentially deliver the solar cell 2 on each carrier 111 to the test position during the rotation process, which can realize the continuity of the test process and improve the test efficiency.

[0079] like Figure 1 , 4 As shown in Figures 5 and 7, in some embodiments, a plurality of carriers 111 are evenly arrayed on a circumference centered on the rotation center of the carrier assembly 11 and the frame 14.

[0080] Multiple carrier components 111 are evenly distributed in an array on a circle centered on the rotation center of the carrier component 11 and the frame 14. That is, the interval angle between two adjacent carrier components 111 is the same. In this way, during the testing of solar cells 2, when the testing process of solar cells 2 on the carrier component 111 is completed and the solar cells 2 on the next carrier component 111 need to be tested, the required rotation angle of the carrier component 11 is fixed, which facilitates the control of the carrier component 11.

[0081] like Figures 1 to 3As shown in Figures 5 and 6, in some embodiments, the carrier assembly 11 is fixedly disposed on the frame 14 along the first direction X, and the probe assembly 12 and the pressure plate assembly 13 are movably disposed on the frame 14 along the first direction X.

[0082] The support component 11 is fixedly mounted on the frame 14 along the first direction X. That is, during the test, the position of the support component 11 along the first direction X is fixed, and it can only rotate around the first direction X but cannot move along the first direction X. In this way, the solar cell 2 can be stably fixed in the support component 11, ensuring that it remains relatively flat and stable during the test.

[0083] The probe assembly 12 and the pressure plate assembly 13 are movably mounted on the frame 14 along the first direction X. Specifically, the relative movement between the probe assembly 12 and the pressure plate assembly 13 and the frame 14 can be achieved by a guide rail slider mechanism or a channel screw mechanism, etc. This application does not limit the implementation of such mechanisms. Specifically, during the test, the probe assembly 12 and the pressure plate assembly 13 gradually move closer to the support assembly 11 along the first direction X, so that the solar cell 2 placed on the support assembly 11 is sandwiched between the probe assembly 12 and the pressure plate assembly 13, realizing the contact between the probe 1211 and the solar cell 2 and the testing of the solar cell 2. After the test is completed, the probe assembly 12 and the pressure plate assembly 13 gradually move away from the support assembly 11 along the first direction X, so that the support assembly 11 can rotate around the frame 14 and move the support member 111 out of the test position while placing the next support member 111 in the test position.

[0084] By fixing the support component 11 to the frame 14 along the first direction X, and movably locating the probe component 12 and the pressure plate component 13 to the frame 14 along the first direction X, the detection function of the solar cell 2 can be realized, while ensuring that the solar cell 2 is stably fixed in the support component 11, ensuring that it remains flat and stable during the test, thereby improving the detection accuracy of the solar cell testing device 1.

[0085] like Figure 1 , 2 As shown in Figures 4 and 6, in some embodiments, the solar cell testing apparatus 1 further includes a mounting component 16, which includes a first slider 161 and a second slider 162 respectively connected to the probe assembly 12 and the pressure plate assembly 13. The frame 14 includes a guide rail 141 extending along a first direction X, and the first slider 161 and the second slider 162 are slidably disposed on the guide rail 141.

[0086] Mounting component 16 includes a first slider 161 and a second slider 162 that are respectively connected to the probe assembly 12 and the pressure plate assembly 13. That is, the probe assembly 12 and the pressure plate assembly 13 are movably connected relative to the frame 14 through the first slider 161 and the second slider 162. In this way, the structure of the probe assembly 12 and the pressure plate assembly 13 can be simplified, and the strength of the probe assembly 12 and the pressure plate assembly 13 can be avoided by setting the sliding groove on the probe assembly 12 and the pressure plate assembly 13, thereby extending the service life of the solar cell testing device 1.

[0087] The frame 14 includes a guide rail 141 extending along a first direction X. The guide rail 141 provides a moving path for the first slider 161 and the second slider 162, thereby improving the moving accuracy and stability of the probe assembly 12 and the pressure plate assembly 13.

[0088] like Figure 4 , 7 As shown in Figure 8, in some embodiments, the probe assembly 12 includes a plurality of probe modules 121 spaced apart along the third direction Z, and a holder 112 is disposed between two adjacent probe modules 121, and the maximum dimension d3 of the holder 112 along the third direction Z is smaller than the spacing distance d2 of the probe modules 121 along the third direction Z.

[0089] The probe assembly 12 includes multiple probe modules 121 spaced apart along the third direction Z. The specific number of probe modules 121 is designed according to the number of grid lines in the solar cell 2. By setting multiple probe modules 121, multiple locations of the solar cell 2 can be tested simultaneously, which can improve testing efficiency and accuracy.

[0090] The holder 112 is positioned between two adjacent probe modules 121. In this way, during the testing of the solar cell 2, the probe 1211 can be avoided, preventing interference between the probe 1211 and the holder 112, which could cause damage or bending of the probe 1211 and affect the service life and testing accuracy of the solar cell testing device 1.

[0091] The maximum dimension d3 of the holder 112 along the third direction Z is smaller than the spacing distance d2 of the probe modules 121 along the third direction Z. In this way, when the probe assembly 12 approaches the carrier assembly 11 to test the solar cell 2, there is a sufficient spacing between the probe modules 121 to avoid the holder 112, ensuring that the holder 112 will not collide with the probe modules 121, thereby improving the service life and measurement accuracy of the solar cell testing device 1.

[0092] like Figure 1 , 5 As shown in Figures 7 and 8, in some embodiments, the holding member 112 is an adsorption member.

[0093] The adsorption component can be a negative pressure suction cup or a Bernoulli suction cup, and this application embodiment does not limit this. Compared with other holding devices, setting the holding member 112 as an adsorption component can reduce the size of the holding member 112, thereby ensuring that the holding member 112 can be accommodated between the probe modules 121 without interfering with the probe 1211.

[0094] like Figure 1 , 2 As shown in Figures 5 and 6, in some embodiments, the solar cell testing apparatus 1 further includes a light-emitting component 17 disposed on the upper side of the pressure plate assembly 13 for emitting simulated sunlight.

[0095] The main function of the light-emitting component 17 is to emit simulated sunlight. The spectrum and intensity of this simulated sunlight are consistent with natural sunlight, and it can accurately simulate the lighting conditions of the solar cell 2 in actual use.

[0096] By emitting simulated sunlight through the light-emitting component 17, the solar cell 2 can be provided with illumination conditions consistent with the actual working environment, so that the test data can truly reflect the performance of the solar cell 2 in actual use, thereby ensuring the accuracy and reliability of the test results of the solar cell test device 1.

[0097] Specifically, such as Figures 1 to 11 As shown, during loading, the solar cell 2 is placed on the support assembly 11 and fixed to the support assembly 111 by the holding member 112. Then, the support assembly 11 rotates relative to the frame 14, thereby rotating the support assembly 111 on which the solar cell 2 is mounted to the test position.

[0098] During testing, the light-emitting component 17 is turned on, and the probe component 12 and the pressure plate component 13 gradually approach the support component 11 along the first direction X. At the same time, the camera 15 acquires the position of the edge of the arched groove 131 in the probe 1211 and the pressure plate component 13. This position ensures that the edge of the probe 1211 and the arched groove 131 coincides in the first direction X, thereby ensuring the accurate relative positional relationship between the probe 1211 and the solar cell 2, so that the probe 1211 contacts the grid line of the solar cell 2, thus completing the testing process of the solar cell 2.

[0099] After the test is completed, the carrier component 11 rotates relative to the frame 14 again to move the tested solar cell 2 out of the test position, and moves the solar cell 2 to be tested on the next carrier component 111 to the test position, and performs the testing and loading / unloading of the solar cell 2 in parallel.

[0100] 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.

[0101] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
