[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figures 1 to 3 As shown, a battery string EL detection device includes a detection frame 1, which is slidably connected to a support frame 8. The support frame 8 is provided with an EL camera 2 and a second drive assembly 9 for driving the detection frame 1 to move horizontally. The EL camera 2 is located on one side of the detection frame 1; a connecting column 3 is provided below the detection frame 1, and the connecting column 3 is connected to a first drive assembly 4 that drives it to move up and down and rotate relative to the detection frame 1. Among them, the connecting column 3 is provided with two conductive blocks 5, two rotating pressing assemblies 6, and a plurality of suction cup assemblies 7 located between the two conductive blocks 5. The two rotating pressing assemblies 6 can cooperate with the corresponding conductive blocks 5 to fix the two solder ribbon ends of the battery string adsorbed and fixed by each suction cup assembly 7.

[0022] Specifically, the inspection frame 1 is positioned above the battery string conveyor line. The first drive assembly 4 comprises two opposing lifting plates 41, which are slidably connected to the inspection frame 1 and connected to a lifting drive 42. The connecting column 3 is rotatably connected between the two lifting plates 41, and one of the lifting plates 41 is provided with a second rotary drive 43 for rotating the connecting column 3. In this embodiment, the lifting drive 42 can be a pneumatic cylinder or an electric linear slide, and the second rotary drive 43 is preferably a servo motor.

[0023] During use, driven by the two lifting drive members 42, the two lifting plates 41 move up and down together, driving the connecting column 3 and each suction cup assembly 7 to move up and down together, so as to take and place the battery string; driven by the second rotating drive member 43, the connecting column 3 and each suction cup assembly 7 rotate together toward or away from the EL camera 2, driving the battery string adsorbed and fixed by each suction cup assembly 7 to rotate together, so that the EL camera 2 can take images of the battery string.

[0024] Furthermore, the detection frame 1 is provided with a limit buffer 44 for limiting the lifting plate 41, which can effectively prevent the battery cells in the battery string from being crushed when taking and placing the battery string, while reducing the impact force between the lifting plate 41 and the detection frame 1, thereby extending the service life of the device.

[0025] like Figure 2 As shown, the suction cup assembly 7 includes a bracket 71 connected to the connecting column 3 and two suction cups 72 mounted on the bracket 71; wherein the two suction cups 72 are symmetrically arranged relative to the connecting column 3. In the initial state, each suction cup assembly 7 is located below the connecting column 3.

[0026] like Figure 3 As shown, the rotary pressing assembly 6 includes a fixed base 61 connected to the connecting column 3, an insulating plate 62 rotatably arranged on the fixed base 61, and a first rotary driving member 63 for driving the insulating plate 62 to rotate relative to the fixed base 61. When in use, the insulating plate 62 is driven to rotate by the first rotary driving member 63, so that the insulating plate 62 can cooperate with the conductive block 5 to achieve clamping or opening.

[0027] In the rotary pressing assembly 6, a limit member 66 is provided on the fixed seat 61. The limit member 66 can be a limit block, a limit rod or a limit buffer. The first rotary driving member 63 is preferably a servo motor.

[0028] Furthermore, the rotary pressing assembly 6 also includes an adjusting seat 64, which is connected to the fixed seat 61 and the connection position can be adjusted up and down; the insulating plate 62 is rotatably connected to the adjusting seat 64 through a rotating arm 65; the conductive block 5 and the first rotating drive member 63 are both installed on the adjusting seat 64.

[0029] In this embodiment, two long first adjustment holes 641 are provided on the adjustment seat 64, and a screw hole 611 corresponding to the first adjustment hole 641 is provided on the fixing seat 61; the adjustment seat 64 is connected to the fixing seat 61 by screwing the locking screw located in the first adjustment hole 641 into the screw hole 611.

[0030] During use, after each suction cup assembly 7 adsorbs and fixes the battery string, the insulating plate 62 rotates toward the conductive block 5 under the drive of the first rotary drive member 63, and cooperates with the conductive block 5 to clamp and fix the end of the soldering ribbon of the battery string. Among them, the conductive block 5 is preferably a copper block.

[0031] In this battery string EL detection device, the mounting position of EL camera 2 on support frame 8 is adjustable horizontally; the tilt angle of EL camera 2 relative to the horizontal plane is also adjustable. Specifically, EL camera 2 is connected to a camera holder 21, which has a circular first mounting hole and an arc-shaped second mounting hole. The support frame 8 has a second, elongated adjustment hole, or multiple mounting holes arranged horizontally. The camera holder 21 is connected to the support frame 8 by two locking screws located in the first and second mounting holes, which are screwed into the second adjustment hole or one of the mounting holes.

[0032] In this battery string EL detection device, the second drive assembly 9 can be an electric linear slide, or a motor-driven pulley assembly can be used, as long as it can drive the detection frame 1 to move linearly relative to the support frame 8. When the battery string test result is unqualified, the second drive assembly 9 drives the detection frame 1 to move relative to the support frame 8 to facilitate sorting and recycling of the unqualified battery strings.

[0033] The utility model provides a battery string EL detection device. When in use, driven by two lifting drive members 42, the connecting column 3 moves downward and then moves upward to reset, so that each suction cup assembly 7 can absorb the battery string from the battery string conveyor line; driven by the first rotating drive member 63, the insulating plate 62 rotates toward the conductive block 5 and cooperates with the conductive block 5 to clamp the end of the welding ribbon of the fixed battery string; driven by the second rotating drive member 43, the connecting column 3, each suction cup assembly 7 and the adsorbed and fixed battery string rotate together toward the EL camera 2; power is turned on for detection, and the EL camera 2 takes an image of the battery string; finally, the placement position of the battery string is selected according to the detection result: if the detection is qualified, the battery string is placed back on the original battery string conveyor line; if the detection is unqualified, the battery string is moved to the recovery conveyor line located on the side of the battery string conveyor line. The entire detection process only requires one time of picking up and placing the moving battery string, which improves the detection efficiency and reduces the risk of the battery string being damaged during the detection process.
