The long pulse xenon lamp light source is located inside the light source housing 170.

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

[0061] Optionally, the positioning camera 154 may be provided in multiple locations.

[0062] For example, Figure 5 The scanning range of the positioning camera is shown. In this embodiment of the application, there are two positioning cameras 154, which are mounted directly above the material tray of the test workbench 141. They are used 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 to the left or to the right.

[0063] Specifically, the camera captures a product image of the battery string assembly and displays it on the screen of the software system 130. The XYT offset of the battery string assembly relative to the calibrated position is calculated. After obtaining the offset, the industrial control computer controls the intelligent robotic arm 122 to match this position for grasping and transporting. The offset can be corrected independently.

After the position is adjusted by visual positioning, the mechanical arm 122 places the sucked battery string on the testing workbench 141, so as to realize automatic conveying of materials.

[0066] It can be understood that the electromagnetic valve controls the opening and closing of the valve core by electromagnetic force, so as to control the flow of fluid. In the suction nozzle tooling 124, the electromagnetic valve group 125 is used to control the flow of gas, so as to realize the suction and release operation of the suction nozzle.

[0072] Specifically, Figure 4 The scanning range of the code scanner is shown. The code scanner scans the battery string on the tray placing mechanism 111 of the feeding process. The bar code and information of each slot assembly obtained from the MES are compared to verify whether the information corresponds. The feeding verification is automatically performed.

[0073] For example, one code reader is used for horizontal movement to perform full-range bar code scanning. The actual scanning success rate is 100%. If the bar code position is fixed, the code scanner 164 can set the position according to the bar code position (the fixed scanning position is set by the man-machine interface) to avoid waste of the cycle time caused by full-range scanning.

[0074] In some embodiments, the software system 130 is detachably arranged on the equipment main frame 100. Specifically, the software system 130 is detachably arranged on the equipment main frame 100 close to the test workbench 141 to generate the test result according to the collected data of the battery string.

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

[0076] For example, please refer to Figure 9 The IV curve interface is shown. The software system 130 uses the resistance load test principle. The initial scanning voltage range is set. The IV data of the battery piece in the bright field is scanned. The standard light intensity IV correction compensation is calculated. The IV curve is drawn. The short-circuit current Isc, the open voltage Voc, the fill factor FF, the maximum power current Ipm, the maximum power voltage Vpm, the maximum power Pmax, the efficiency Eff, the string Rs, the parallel group Rsh and the light intensity Insol are calculated. The data are saved to the database.

[0077] For example, please refer to Figure 10 When the assembly string containing the unmatched battery is tested, the IV curve appears an abnormal step trend (an inflection point) similar to the figure, so that it is identified which string assembly has the unmatched battery.

[0078] Specifically, the solar cell module test system of the embodiment of the present application interfaces with the AGV or MGV, or directly places multiple solar cell strings on the tray 111a of the tray 111a placing mechanism in a manual loading manner; the industrial computer controls the mechanical arm 122 to move to the tray 111a placing mechanism, drives the mechanical arm 122 to grab the cell string, controls the suction nozzle to suck the cell string through the electromagnetic valve group 125; the industrial computer controls the code scanner 164 to scan the code of the cell string, reads the module number of the cell string, and compares the slot module bar code and information obtained from the MES to verify whether the information corresponds, if corresponding, then the next step is performed, that is, after the mechanical arm 122 grabs the cell string, the mechanical arm 122 is moved to the test workbench 141, and after the cell string is positioned by the positioning camera 154, the mechanical arm 122 places the cell string on the interconnection sheet 147 on the test workbench 141, the double-head probe 143 is driven by the clamp 142 to press down and contact the test electrode 146 on the test copper 145, so as to measure the voltage and current data of the cell string, and the collected data is sent 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, so as to identify which string of components has a mismatched cell. It can be understood that after the cell string is tested, the mechanical arm 122 is controlled to grab the cell string, and the five-axis module controls the mechanical arm 122 to move from the test area to the feeding and discharging area for discharging.
