During the processing, the upper cover and the lower cover need to be positioned and assembled. The upper cover has a snap structure and the lower cover is provided with a snap groove. During assembly, the snap needs to be installed in the snap groove.

[0003] The existing assembly method generally adopts a clamping claw to directly clamp the upper cover and press it onto the lower shell from top to bottom. With the above assembly method, there may be a situation where the buckle is not assembled into the buckle groove due to the incorrect angle of the upper cover. Therefore, the upper cover needs to be aligned before assembly. In addition, the charger can have a variety of specifications. Chargers of different specifications have different sizes and different buckle positions. The existing assembly equipment is difficult to adapt to the diverse assembly requirements of the charger shell. Therefore, a charger circuit board automatic assembly detection equipment is required.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Example:

[0025] refer to Figure 1-Figure 7 The shown automatic assembly and re-inspection equipment for a mobile phone charger shell comprises a frame, on which a carrier conveying mechanism 1 and a carrier reflux mechanism 2 are arranged, and on the frame, an upper visual inspection module 3, a lower visual inspection module 4, a visual re-inspection module 5, a flipping mechanism 6, a transfer assembly robot 7 and a lifting and lowering flow line 8 are arranged beside the carrier conveying mechanism 1. The visual re-inspection module 5 comprises 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 table of the first rotating device 502, the camera seat 504 is hinged to the rotating seat 503, the flipping mechanism 6 comprises a first XYZ moving mechanism 601, a second rotating device 602, a rotating seat 603 and a first clamping cylinder 604, and the transfer assembly robot 7 comprises a second XYZ moving mechanism 701, a third rotating device 702, a material picking seat 703 and a second clamping cylinder 704.

[0026] Two carrier conveying mechanisms 1 can be set in the frame, one for conveying the carrier loaded with the upper cover, and the other for conveying the carrier loaded with the lower cover. The blocking cylinder is used to block the carrier so that the carrier is transported to the designated workstation and stops. The lifting cylinder is used to lift the carrier on the carrier conveying mechanism 1. A slide 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 visual inspection module 3 is used to take a picture 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, and then place it again. The upper light source can provide supplementary light in an environment with poor light. The lower visual inspection module 4 is used to take a picture of the lower cover, and guide the transfer assembly robot 7 to grab the lower cover from the unlocked lower cover carrier, adjust its angle and orientation, and then press it onto the aligned upper cover to complete the assembly.

[0028] The visual re-inspection module is used to detect the gap around the upper cover and the lower cover after assembly. If the gap is too large, it means that the buckle does not match the buckle groove. The re-inspection camera holder 504 is fixedly connected to the C-shaped groove by a screw. The angle of the camera holder 504 can be adjusted to adapt to the visual inspection of products of different specifications.

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

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

[0031] The working principle of the present invention is:

[0032] The carrier mounted on the upper cover and the carrier loaded with the lower cover are transported respectively by two carrier transport mechanisms 1. 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, and then the slide cylinder drives the push plate to move toward the carrier, and unlocks the lower cover carrier and the upper cover carrier by squeezing the movable end of the elastic clamp on the carrier;

[0033] The first XYZ moving mechanism drives 601 and the first clamping cylinder 604 to clamp the lower cover, and the second rotating seat 602 drives the rotating seat 603 and the first clamping cylinder 604 to flip 180 degrees. Then the second XYZ moving mechanism 701 drives one of the second clamping cylinders 704 to move and clamp the flipped lower cover, and move it to the lower visual inspection module 4 for alignment (the lower visual inspection module 4 is used to take a picture of the lower cover, guide the transfer assembly robot 7 to grab the lower cover from the unlocked lower cover carrier, adjust its angle 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 clamping cylinder 704 to move and clamp the upper cover to the upper visual inspection module for alignment (the upper visual inspection module 3 is used to take a picture 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 orientation, and then place it in the carrier).

[0034] After the alignment is completed, the aligned lower cover is assembled on the aligned upper cover to complete the assembly. After the blocking cylinder and the lifting cylinder are reset, the assembled finished product continues to flow to the re-inspection station. The re-inspection CCD camera 505 detects whether there is a too large gap around the upper cover and the lower cover. 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 workstation.

[0035] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
