However, some chargers have clips on the side of the slot where the circuit board is installed inside the charger housing. Using the above assembly method, the circuit board will come into contact with and be squeezed by the clips, resulting in defective products. Therefore, there is a need for an automatic assembly and testing device for charger circuit boards. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] Example:

[0027] refer to Figures 1-8The device shown is an automatic assembly and testing equipment for charger circuit boards, including a frame. A first conveyor line 1, a second conveyor line 2, and a charger clip pulling mechanism 5 are arranged on the frame. A first handling robot 3 is arranged next to the first conveyor line 1, and a second handling robot 4 is arranged next to the second conveyor line 2. A vision inspection mechanism 6 is arranged on the frame next to the charger clip pulling mechanism 5. The charger clip pulling mechanism 5 includes an XY moving module 501, a shell elastic positioning component 502, a pulling translation module 503, a misalignment cylinder 504, and a pulling hook plate 505. The shell elastic positioning component 502 is fixedly connected to the moving platform of the XY moving module 501, and a tension sensor is fixedly connected to the moving platform of the misalignment cylinder 504.

[0028] A push-unlock cylinder for positioning the conveyor belts is installed on the frame beside the first conveyor line 1 and the second conveyor line 2, along with a transfer carrier for placing charger housings or circuit boards. A return line for recovering empty carriers is installed inside the frame. A blocking cylinder is fixedly connected to the frame below the first conveyor line 1 and the second conveyor line 2. The blocking cylinder blocks the carriers during transport, stopping them at the loading station. A lifting module lifts the positioned carriers, and then the push-unlock cylinder releases the clamping ends on the carriers carrying charger housings and circuit boards (the carriers have elastic clamping structures that hold the product after it is placed on the carrier). This facilitates subsequent robotic transfer. The blocking cylinder is misaligned with the conveyor belt to prevent interference from the conveyor belt on the lifting action of the blocking cylinder piston rod.

[0029] A scanning mechanism is fixedly connected to the frame on both sides of the first conveyor line 1 and the second conveyor line 2. The scanning mechanism includes a scanning translation module and a scanner. The scanner can scan the QR code on the carrier to prevent the wrong material from flowing into the production line. The scanner is fixedly connected to the moving platform of the scanning translation module. The scanning translation module is fixedly connected to the frame. The scanning translation module is used to drive the scanner to translate.

[0030] The first handling robot 3 includes a first XYZ moving module and a first gripper cylinder. The first XYZ moving module drives the first gripper cylinder to move and transfer the charger housing. The second handling robot 4 includes a second XYZ moving module, a rotating device, and a second gripper cylinder. The second XYZ moving module drives the second gripper cylinder to move and transfer the circuit board workpiece. The rotating device is used to adjust the installation angle before the circuit board is assembled. The pull hook plate 505 is fixedly connected to the detection end of the tension sensor. When the pull hook plate 505 pulls the buckle on the charger housing, the tension data is detected to prevent the pull hook plate 505 from over-pulling the buckle, causing irreversible deformation or buckle breakage.

[0031] The positioning seat 5022 of the outer shell elastic positioning component 502 is used to position the charger housing. When the main slider 5024 is not in contact with the baffle, the second sliding chuck 5026 and the first sliding chuck 5023 are in a clamping state on the charger housing under the action of the spring 5027. When the XY moving module drives the base 5021 to slide to the loading and unloading station, the main slider 5024 slides in the opposite direction to the traveling direction of the base 5021 under the obstruction of the baffle. At this time, when the inclined slider 5025 slides in the limiting groove, it pushes the second sliding chuck 5026 to slide away from the positioning seat 5022. The first sliding chuck 5026 is released synchronously with the sliding of the main slider 5024. At this time, the charger housing can be loaded or unloaded.

[0032] The visual inspection mechanism 6 includes a side CCD camera, a lower CCD camera, and an upper CCD camera, which can inspect from multiple angles. The side CCD camera and the lower CCD camera are fixedly connected to the frame, and the upper CCD camera is fixed on the second handling robot 4.

[0033] The working principle of this utility model is as follows: In use, the carrier for loading the charger housing and the carrier for loading the circuit board are transported via the first conveyor line 1 and the second conveyor line 2, respectively. At the loading station, the carrier at the loading station is vertically lifted by the lifting module. At this time, the XY moving module 501 drives the shell elastic positioning component 502 to the baffle, causing the first sliding clamp 5023 and the second sliding clamp 5026 to loosen. Then, the first handling robot 3 transports the charger housing to the intermediate transfer device. The second handling robot 4 adds the circuit board and moves it to directly above the lower CCD camera. Next, the first handling robot 3 transfers the charger housing to the positioning seat 5022. The XY moving module 501 drives the shell elastic positioning component 502 to move to the assembly station. At this time, under the action of the spring 5027, the first sliding clamp 5023 and the second sliding clamp 5026 tighten the charger housing. Then, the charger buckle pulling mechanism 5... The pull-out translation module 503 drives the pull-out hook plate 505 to move horizontally above the charger housing. Then, the misalignment cylinder 504 drives the pull-out hook plate 505 to descend to the inside of the buckle. The pull-out translation module 503 drives the pull-out hook plate 505 to pull the buckle outward, causing the buckle to misalign with the slot of the mounting circuit board. During this process, the deformation angle of the buckle is detected by taking pictures with the side CCD camera, and the circuit board is photographed by the lower CCD camera. The second gripper cylinder is rotated by the rotating device to finely adjust the angle of the circuit board. Then, the second handling robot 4 inserts the adjusted circuit board vertically downward into the corresponding slot of the charger housing. After that, the pull-out hook plate 505 is reset, thus completing the assembly of the circuit board. The upper CCD camera performs visual inspection on the assembled finished product. Finally, the shell elastic positioning component 502 moves to the loading and unloading station, and the first handling robot 4 transfers the assembled product to the corresponding charger housing carrier. It is then transported to the subsequent workstation for processing via the first conveyor line 1.
