[0002] A mobile phone charger is an accessory used to charge a mobile phone. It mainly consists of an upper cover, a lower cover, a circuit board, and a plug. During the manufacturing process, the upper and lower covers need to be positioned and assembled. The upper cover has a snap-fit ​​structure, and the lower cover has a snap-fit ​​groove. During assembly, the snap-fit ​​needs to be fastened into the snap-fit ​​groove.

[0003] Existing assembly methods typically involve grippers directly clamping the top cover and pressing it onto the bottom shell from top to bottom. However, this method can lead to situations where the clips fail to fit into their slots due to incorrect angles of the top cover. Therefore, the top cover needs to be aligned before assembly. Furthermore, chargers can come in various sizes and have different clip positions. Existing assembly equipment struggles to meet the diverse assembly requirements of charger housings. Consequently, an automated assembly and testing device for charger circuit boards is needed. Utility Model Content

[0023] 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.

[0024] Example:

[0025] refer to Figures 1-7 The illustrated automatic assembly and re-inspection equipment for mobile phone charger casings includes a frame, on which a carrier conveying mechanism 1 and a carrier return mechanism 2 are mounted. Next to the carrier conveying mechanism 1 on the frame are an upper vision inspection module 3, a lower vision inspection module 4, a vision re-inspection module 5, a flipping mechanism 6, a transfer assembly robot 7, and a lifting streamline 8. The vision re-inspection module 5 includes a re-inspection translation mechanism 501, a first rotating device 502, a rotating seat 503, a camera seat 504, and a re-inspection CCD camera 505. The rotating seat 503 is fixedly connected to the rotating platform of the first rotating device 502, and the camera seat 504 is hinged to the rotating seat 503. The flipping mechanism 6 includes a first XYZ movement mechanism 601, a second rotating device 602, a rotating seat 603, and a first gripper cylinder 604. The transfer assembly robot 7 includes a second XYZ movement mechanism 701, a third rotating device 702, a material handling seat 703, and a second gripper cylinder 704.

[0026] Two carrier conveying mechanisms 1 can be installed in the frame. One is used to convey carriers loaded with upper covers, and the other is used to convey carriers loaded with lower covers. A blocking cylinder is used to block the carriers so that they are conveyed to a designated work station and stop. A lifting cylinder is used to lift the carriers on the carrier conveying mechanism 1. A sliding table cylinder is fixedly connected to the side of the carrier conveying mechanism 1 on the frame to drive the push plate to unlock the elastic clamping structure on the carrier, thereby loosening the product.

[0027] The upper vision inspection module 3 is used to photograph the upper cover and guide the transfer assembly robot 7 to pick up the upper cover from the unlocked upper cover carrier, adjust its angle and orientation, and then place it. The upper light source can provide supplemental lighting in low-light environments. The lower vision inspection module 4 is used to photograph the lower cover and guide the transfer assembly robot 7 to pick up the lower cover from the unlocked lower cover carrier, adjust its angle and orientation, align it, and then press it onto the aligned upper cover to complete the assembly.

[0028] The visual inspection module is used to detect the gaps around the top and bottom covers after assembly. If the gaps are too large, it indicates that the buckles do not match the buckle slots. The inspection camera mount 504 is fixedly connected to the C-shaped groove by a screw. The angle of the camera mount 504 can be adjusted to adapt to the visual inspection of products of different specifications.

[0029] The flipping mechanism 6 is used to grip the lower cover and flip it 180° to facilitate subsequent detection and alignment by the lower vision inspection module 4. The first XYZ moving mechanism 601 is used to drive the second rotating device 602 to perform translational movement. The second rotating device 602 is used to drive the rotating seat 603 and the first gripper cylinder 604 to flip.

[0030] The second XYZ moving mechanism 701 is used to drive the third rotating device 702 to translate. The picking seat 703 is slidably connected to the rotating table of the third rotating device 702. A spring is provided between the picking seat 703 and the rotating table of the third rotating device 702. During assembly, the non-rigid structure can avoid the shell from breaking. The second gripper cylinder 704 is fixedly connected to the picking seat 703.

[0031] The working principle of this utility model is as follows:

[0032] The carrier with the upper cover and the carrier with the lower cover are transported by two carrier conveying mechanisms 1 respectively. When the lower cover carrier and the upper cover carrier arrive at the assembly station, the lifting cylinder lifts the lower cover carrier and the upper cover carrier upward. Then the slide cylinder drives the push plate to move towards the carrier. The lower cover carrier and the upper cover carrier are unlocked by squeezing the movable end of the elastic clamp on the carrier.

[0033] The first XYZ moving mechanism drives the first gripper cylinder 604 to grip the lower cover. The second rotating mechanism 602 drives the rotating seat 603 and the first gripper cylinder 604 to rotate 180 degrees. Then, the second XYZ moving mechanism 701 drives one of the second gripper cylinders 704 to move and grip the rotated lower cover, and moves it to the lower vision detection module 4 for alignment (the lower vision detection module 4 is used to take pictures of the lower cover, guide the transfer assembly robot 7 to grab the lower cover from the unlocked lower cover carrier, adjust its angle and orientation for alignment, and then press it onto the aligned upper cover to complete the assembly). The second XYZ moving mechanism 701 drives another second gripper cylinder 704 to move and grip the upper cover to the upper vision detection module for alignment (the upper vision detection module 3 is used to take pictures of the upper cover, and guide the transfer assembly robot 7 to grab the upper cover from the unlocked upper cover carrier, adjust its angle and orientation for placement in the carrier).

[0034] After alignment, the aligned lower cover is assembled onto the aligned upper cover to complete the assembly. After the blocking cylinder and lifting cylinder are reset, the assembled finished products continue to flow to the re-inspection station. The re-inspection CCD camera 505 checks whether the gaps around the upper and lower covers are too large. If the gap is too large, it means that the buckle does not match the buckle groove. Otherwise, it is a finished product. According to the inspection results, the defective products are unloaded and the finished products are transferred to the next station.

[0035] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
