[0002] In today's fast-paced consumer electronics market, the portability and durability of charger plugs have become key concerns for consumers. To meet these demands, charger plugs are becoming increasingly smaller and more diverse in shape. Plugs with symmetrical structures, such as cubes and rectangular blocks, are particularly popular due to their unique design. However, this miniaturization and diversification present new challenges in the production process, particularly when applying protective films such as release paper to the plugs.
[0003] In the production process of charger plugs, protective film coating is a crucial step. It not only protects the plug from damage during transportation and storage, but also provides a good feel when plugging and unplugging the product. However, existing coating technology faces a major challenge: how to accurately and efficiently identify and ensure the correct orientation of the plug. Because the front and back of symmetrical plugs, such as square ones, are highly similar in appearance, traditional automated inspection equipment has difficulty distinguishing the front and back of the plug, resulting in increased errors and rework rates during the production process.

[0030] The charging plug laminating equipment described in this embodiment uses directional detection to determine the processing orientation of the plug 400. A limiting mechanism 320 ensures that the attachment operation is performed with the plug 400 accurately positioned, thereby improving the yield rate. Compared to current conventional laminating equipment, this application is compatible with processing plugs 400 of various shapes and can significantly reduce the cost of defective products. It also improves the controllability, efficiency, and flexibility of the processing process, providing new ideas for plug laminating equipment and processes.
[0031] See also Figures 1 to 3 As shown, the processing table 100 in this embodiment includes a table body 110 and a plurality of positioning blocks 120. The plurality of positioning blocks 120 are arranged on the table body 110 to enclose the detection processing site. Specifically, in this embodiment, four positioning blocks 120 are provided.

[0036] This embodiment also includes a control system, to which the attachment mechanism 200, the detection assembly 310, and the limit mechanism 320 are each signal-connected. During actual production and processing, the operator can use the control system to adjust the above-mentioned structures in real time, thereby increasing the flexibility of the device. Parameters can also be preset through the control system, thereby increasing the automation level of the device.

[0039] Step S1: First, lay the release film on the processing table with the connection surface facing upward, and then place the charging plug on the release film and position it in the detection processing position;
[0040] Step S2: The metal proximity switch is brought close to the plug to be processed, so that the metal proximity switch can determine the position of the plug by detecting the metal structure on the plug.
[0041] When it is detected that the orientation of the plug is correct, the limiting mechanism is moved from the extended stop state to the retracted avoidance state, and then the attaching mechanism is moved toward the plug to attach the protective film to the plug;
[0042] When the plug orientation is detected to be incorrect, the limiting mechanism is kept in the extended stop state, the plug orientation is adjusted and re-detected until the plug orientation is detected to be correct, and then the attaching mechanism is moved toward the plug to attach the protective film to the plug.
[0043] Furthermore, in step S2 of this embodiment, the metal proximity switch transmits the detection result to the control system, and the control system drives the driver in the limit mechanism to move so that the limit head connected to the driver moves toward / away from the push block of the attachment mechanism.
[0044] In summary, the charging plug laminating equipment and method described in the present invention uses directional detection to determine the processing orientation of the plug, and uses a limiting mechanism to ensure that the attachment operation is performed under the premise of accurate plug orientation, thereby improving the yield rate. Compared with current conventional laminating equipment, this application is compatible with processing plugs of different shapes and can significantly reduce the cost waste caused by defective products. At the same time, it can also improve the controllability, processing efficiency, and flexibility of the processing process, providing new ideas for plug laminating processing equipment and processes.
