[0051] As described above, the embodiment of the present application controls the lifting mechanism 112 of the loading and unloading component 110 through various components of the industrial computer control system to lift the tray placement mechanism 111 to a set height, and the intelligent robotic arm 122 grabs the battery string from the tray placement mechanism 111 and transports it to the test area 102. The battery string in the test area 102 is tested and the test results are generated through the test component and software system 130. The entire process is automated, which improves the generation efficiency, improves the repeatability of the test, and avoids the problem of damage to the battery string.

[0052] It can be understood that the set height is set according to the needs and the specific component setting structure, and the embodiment of the present application does not limit the specific value of the set height.

[0054] In some embodiments, please refer to Figure 7 and Figure 8 The table top of the test workbench 141 is installed with a fiberglass board, and the milling groove of the fiberglass board is provided with a variety of vacuum adsorption slots and test coppers 145 corresponding to the vacuum adsorption slots, and two test electrodes 146 are provided on the test copper 145, and an interconnection piece 147 is provided on the test copper 145; the test workbench 141 is provided with an automatic slide rail device, and the double-headed probe 143 fixture 142 is slidably connected to the automatic slide rail device, the double-headed probe 143 is arranged corresponding to the test electrode 146, and the double-headed probe 143 fixture 142 is also provided with a driving motor for driving the double-headed probe 143 to move.

[0055] For example, please refer to Figure 7 The test bench 141 of the embodiment of the present application is divided into two areas (two vacuum adsorption slots), which are used for placing and testing two different specifications of battery strings. For example, the size of the test bench 141 is 2000mm*500mm. In order to meet the battery string arrangement of 30.3*40, 40*60.5, 40*80 sizes, 32 pieces in string length, and 3 parallel numbers, and 144.6*66.5, 27 strings, and 1 parallel number, the battery string arrangement is measured and designed. Figure 7 The arrangement is divided into two areas. The battery string with a parallel number of * 3 is tested in the lower area, and the battery string with a parallel number of 1 is tested in the upper area.

[0056] Please refer to Figure 8 , showing the test copper 145, the interconnection sheet 147 and the test electrode 146. By placing the battery string on the interconnection sheet 147, the battery string can be conductively connected to the test copper 145 through the interconnection sheet 147, so that the current and voltage of the battery string can be obtained through the two test electrodes 146.

[0057] Specifically, the battery string is placed on the interconnection sheet 147, and a conductive connection is achieved with the test copper 145 through the interconnection sheet 147. The battery string is adsorbed by the vacuum adsorption slot, and the industrial computer controls the double-headed probe 143 and the clamp 142 to move to the position of the battery string. The driving motor controls the double-headed probe 143 to move and contact with the two test electrodes 146 of the test copper 145, so as to realize the data collection of the current and voltage of the battery string.

[0058] In some embodiments, the light source module includes: a long pulse xenon lamp light source, which is disposed on the top of the test area 102; and the long pulse xenon lamp light source provides illumination for the test area 102.

[0059] Optional, see Figure 1The light source module includes a light source housing 170 , which is disposed at the upper end of the device main frame 100 and communicated with the test area 102 , and a long pulse xenon lamp light source is disposed in the light source housing 170 .

[0060] In some embodiments, please refer to Figure 6 The camera device includes a camera supporting frame 151, a camera slide 152, a first connecting member 153 and a positioning camera 154. The camera slide 152 is located on the camera supporting frame 151. The first connecting member 153 is slidably connected to the camera slide 152. The first connecting member 153 is used to fix the positioning camera 154. The positioning camera 154 is arranged directly above the test workbench 141.

[0061] Optionally, there are multiple positioning cameras 154.

[0062] For example, Figure 5 The scanning range of the positioning camera is shown. In the embodiment of the present application, two positioning cameras 154 are arranged directly above the material tray of the test workbench 141 to calibrate the actual position of the battery string assembly in the tray 111a and guide the intelligent robotic arm 122 to grasp it. The two cameras are used to distinguish whether the actual position of the battery string assembly in the material tray is on the left or right.

[0063] Specifically, the camera captures the product image of the battery string assembly and displays it on the display screen of the software system 130, and the XYT offset of the battery string assembly and the calibrated position is calculated. After the offset is obtained, the industrial computer controls the intelligent robotic arm 122 to match this position for grabbing and transporting, and the offset can be corrected separately. It is understandable that there are many existing implementation methods for calculating and correcting the offset, and the embodiments of the present application are not limited to this. Optionally, the position of the positioning camera 154 is adjusted using a motor control method according to the position of the battery string assembly, which is convenient and quick to switch and realize rapid calibration; optionally, a sensor is installed above the tray of the battery string assembly, and the sensor is used to verify the length of the assembly, and control the further adjustment of the position of the positioning camera 154.

[0064] In some embodiments, please refer to Figure 5 The intelligent robotic arm 122 includes: a mechanical slide rail 121, a robotic arm 122 slidably connected to the mechanical slide rail 121, and a five-axis module for driving the robotic arm 122. A gripper 123 and a plurality of suction nozzle fixtures 124 connected to the gripper 123 are provided at the end of the robotic arm 122, and a solenoid valve group 125 is provided on the suction nozzle fixture 124; the loading and unloading area 101 is provided with a support frame 126 for placing the mechanical slide rail 121, and the mechanical slide rail 121 extends from the support frame 126 to the test workbench 141 and is placed on the test workbench 141.

[0065] Specifically, the five-axis module is used to control the robot arm 122 to grab the battery string of the tray placement mechanism 111, and the solenoid valve group 125 is used to control the suction nozzle to suck the battery string. The five-axis module is used to drive the robot arm 122 to move from the loading and unloading area 101 to the testing area 102 through the mechanical slide rail 121. After adjusting the position through visual positioning, the robot arm 122 places the sucked battery string on the testing workbench 141 to realize automatic material transportation.

[0066] It is understandable that the solenoid valve controls the opening and closing of the valve core through electromagnetic force, thereby controlling the flow of the fluid. In the suction nozzle tooling 124, the solenoid valve group 125 is used to control the flow of gas to achieve the suction and release operations of the suction nozzle.

[0067] For example, please refer to Figure 5 The robot arm 122 is synchronously driven by a 5-axis module and is equipped with 192 suction nozzles. It can simultaneously absorb up to 96 battery string components (32*3 arrangement). The 32 groups of suction nozzles are controlled by separate solenoid valves. The number of components of different lengths can be selected through the human-machine interface to complete the switch. Among them, each group of suction nozzles is installed on a fixed profile, connected by bolts, and the position can be adjusted. Multiple sets of suction nozzle fixtures 124 are configured, and the fixtures of products with different specifications or different spacings can be replaced to achieve fast switching.

[0068] In some embodiments, please refer to Figure 3 and Figure 4 The tray placement mechanism 111 includes several layers of trays 111a, and each layer of the trays 111a is correspondingly provided with a telescopic device, and the telescopic device drives the trays 111a to move in and out.

[0069] In the above implementation process, the lifting mechanism 112 is controlled to raise the tray placement mechanism 111 to a set height, and the telescopic device drives the tray out so that the intelligent robotic arm 122 can grab the material from the tray to realize automatic loading.

[0070] Optional, see Figure 3 Two groups of vertical frames 113 are installed on the outer side of the tray placement mechanism 111, and the lifting mechanism 112 is arranged on the vertical frame 113. The tray placement mechanism 111 is connected with the lifting mechanism 112. Optionally, the lifting mechanism 112 includes a lifting plate, a lifting motor, a guide rail or a belt, etc., which is used to drive the tray placement mechanism 111 to lift and lower; it can be understood that there are many existing means for realizing the lifting mechanism 112, and the embodiment of the present application does not limit the specific structure of the lifting mechanism 112.

[0071] In some embodiments, please refer to Figure 4The loading and unloading assembly 110 also includes a scanning device, which is located in the loading and unloading area 101; the scanning device includes: a scanner 164 support frame 161, a scanner 164 slide rail 162, a second connecting member 163 and a scanner 164, the scanner 164 slide rail 162 is located on the scanner 164 support frame 161, the second connecting member 163 is slidably connected to the scanner 164 slide rail 162, the second connecting member 163 is used to fix the scanner 164, and the scanner 164 is arranged above the loading and unloading area 101.

[0072] Specifically, Figure 4 The scanning range of the barcode scanner is shown. The battery string on the tray placement mechanism 111 of the loading process is scanned by the scanning device, and the barcode and information of each slot component obtained from the MES are compared to verify whether the information corresponds, thereby realizing automated loading verification.

[0073] For example, a barcode reader is used to scan the entire barcode horizontally, and the actual scanning success rate is 100%. If the barcode position is fixed, the barcode scanner 164 can be set according to the barcode position (the human-machine interface sets a fixed scanning position) to avoid wasting cycle time caused by full-range scanning.

[0074] In some embodiments, the software system 130 is detachably mounted on the device main frame 100; specifically, the software system 130 is detachably mounted on the device main frame 100 near the test workbench 141 to generate test results based on the collected data of the battery string.

[0075] Optionally, the software system 130 includes a display screen and a processing system.

[0076] For example, please refer to Fig. 9 , which is the IV curve interface diagram. The software system 130 adopts the resistive load test principle: setting the scanning voltage starting range, scanning the bright field IV data of the battery cell, calculating the standard light intensity IV correction compensation, drawing the IV curve, calculating the battery cell short-circuit current Isc, opening voltage Voc, fill factor FF, maximum power current Ipm, maximum power voltage Vpm, maximum power Pmax, efficiency Eff, string group Rs, parallel group Rsh, light intensity Insol and other data, and saving them to the database.

[0077] For example, please refer to Fig.10 When testing a component string containing mismatched cells, the IV curve shows an abnormal step trend (inflection point) as shown in the figure, thereby identifying which component string has mismatched cells.

[0078] Specifically, the solar cell module testing system of the embodiment of the present application is connected to the AGV or MGV, or a plurality of solar cell strings are directly placed on the tray 111a of the tray 111a placement mechanism by manual loading; the industrial computer controls the mechanical arm 122 to move to the tray 111a placement mechanism, drives the mechanical arm 122 to grab the battery string, and controls the suction nozzle 125 to suck the battery string; the industrial computer controls the barcode scanner 164 to scan the battery string, read the component number of the battery string, and compare the barcode and information of each slot component obtained from the MES to verify whether the information corresponds. If it corresponds, the next step is performed, that is, the mechanical arm 122 is controlled to scan the battery string, read the component number of the battery string, and compare the barcode and information of each slot component obtained from the MES to verify whether the information corresponds. If it corresponds, the next step is performed, that is, the mechanical arm 122 is controlled to scan the battery string, read the component number of the battery string, and compare the component number of each slot component obtained from the MES to verify whether the information corresponds. If it corresponds, the next step is performed, that is, the mechanical arm 122 is controlled to scan the battery string, read the component number of ... 22 After grabbing the battery string, the robot 122 is moved to the test workbench 141, and after positioning the battery string through the positioning camera 154, the robot 122 places the battery string on the interconnection sheet 147 on the test workbench 141, and drives the double-headed probe 143 through the double-headed probe 143 fixture 142 to press down and contact the test electrode 146 on the test copper 145, thereby measuring the voltage and current data of the battery string, and sending the collected data to the software system 130, the software system 130 draws the IV curve and displays the curve on the display screen, so that it can be directly seen whether the curve is normal, thereby identifying which string of components has mismatched batteries. It can be understood that after the test of the battery string is completed, the robot 122 is controlled to grab the battery string, and the robot 122 is controlled by the five-axis module to move from the test area to the loading and unloading area for unloading.
