Description

Technical Field

[0001] This utility model relates to the field of mobile phone SIM card tray processing technology, and in particular to a universal jig for SIM card tray painting. Background Technology

[0002] Currently, the side caps of SIM card trays protrude from the phone's frame. To match the color of the phone's frame, these side caps need to be painted during the tray manufacturing process. The current painting process involves placing the SIM card tray on a fixture and passing it through a painting line for painting.

[0003] like Figure 1 As shown, the existing jig for card tray painting includes a bottom cover and a top cover 1, forming a cavity between them. The top cover has multiple card tray slots 2, into which the card trays are inserted. To prevent the card trays from falling out during the painting process, the card trays need to be interference-fitted with the jig's card tray slots. This places high demands on the jig's dimensions. If the fit is too tight, the card trays may be damaged, and they may be easily bent during loading and unloading. Conversely, if the fit is too loose, the card trays may easily fall out.

[0004] At the same time, the dimensions of the card holder fixture need to be strictly controlled, and the card holder processing for each project requires the creation of a new card holder mold, which increases the mold cost.

[0005] When unloading cassettes, each cassette needs to be clamped out of the fixture one by one, which makes unloading difficult and increases the workload for the unloading personnel. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model designs a universal fixture for carton painting.

[0007] The present invention adopts the following technical solution: A universal jig for card tray painting includes a bottom cover and a top cover, forming a cavity between the bottom cover and the top cover. The top cover has multiple card tray slots. An intermediate layer is provided between the bottom cover and the top cover. The intermediate layer is detachably and fixedly connected to the bottom cover. An elastic gripper is provided on the intermediate layer corresponding to each card tray slot. The elastic gripper is used to hold the lower part of the card tray.

[0008] Preferably, the elastic gripper is formed by two plastic grippers distributed left and right.

[0009] Preferably, hooks are fixedly connected to the four corners of the intermediate interlayer, and slots are correspondingly opened on the bottom cover, with the hooks and slots engaging and securing them.

[0010] Preferably, the bottom cover and the top cover are detachably snap-fitted together.

[0011] Preferably, the elastic gripper and the intermediate interlayer are integrally formed by injection molding.

[0012] The beneficial effects of this utility model are as follows: This utility model designs a universal jig for card tray painting, which adds an intermediate layer. This reduces the requirement for the gap size between the card tray slot and the card tray, allowing for a more spacious design. The clamping is controlled by the elastic claws of the intermediate layer, which can accommodate card trays of more project sizes. At the same time, when unloading, only the bottom cover and the top cover need to be removed. After the bottom cover is opened, the card tray automatically detaches from the elastic claws. Then, simply invert the top cover, and the card tray can fall off naturally for unloading. This results in high unloading efficiency and saves labor costs. Attached Figure Description

[0014] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example: Figures 2-3 As shown, a universal jig for card tray painting includes a bottom cover 3 and a top cover 1, forming a cavity between the bottom cover and the top cover. The top cover has multiple card tray slots 2. An intermediate layer 4 is provided between the bottom cover and the top cover. The intermediate layer is detachably and fixedly connected to the bottom cover. An elastic gripper 5 is provided on the intermediate layer corresponding to each card tray slot. The elastic gripper is used to hold the lower part of the card tray.

[0015] The elastic gripper is formed by two plastic grippers distributed on the left and right.

[0016] The four corners of the middle interlayer are fixedly connected with hooks 7, and the bottom cover is provided with corresponding slots 6. The hooks and slots are engaged and fixed.

[0017] The bottom cover and top cover are detachably snap-fitted together. The elastic grippers and the middle interlayer are integrally molded by injection molding.

[0018] This utility model designs a universal jig for card tray painting, which adds an intermediate layer. This reduces the required gap between the card tray slot and the card tray 8, allowing for a more spacious design. The clamping is controlled by the elastic claws of the intermediate layer, which can accommodate card trays of more project sizes. When unloading, simply remove the bottom cover and the top cover. As the bottom cover opens, the card tray automatically detaches from the elastic claws. Then, simply invert the top cover, and the card tray will fall off naturally for unloading. This method is highly efficient and saves labor costs.

[0019] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
