Description

Technical Field

[0001] This utility model relates to the field of mobile phone button processing, and in particular to a positioning fixture for mobile phone button processing. Background Technology

[0002] With the rapid development of mobile communication technology, mobile phones have become an indispensable necessity in people's daily lives. As a key component of human-computer interaction, the appearance quality, tactile consistency, and assembly precision of mobile phone buttons directly affect the overall quality and user experience. Currently, mobile phone buttons (including decorative pieces for physical buttons and touch buttons) are mostly processed using a variety of techniques such as precision injection molding, CNC engraving, surface coating (PVD), spraying, and laser engraving.

[0003] In the aforementioned processing, especially in CNC precision machining, inspection, pad printing, and assembly, accurate positioning and reliable clamping of mobile phone buttons are required. However, existing positioning fixtures typically require dedicated fixtures for different models, sizes, and shapes of mobile phone buttons (such as volume buttons, power buttons, and home buttons). Frequent fixture changes not only reduce production efficiency but also increase equipment costs. Therefore, we propose a positioning fixture for mobile phone button processing to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for processing mobile phone buttons, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning fixture for processing mobile phone buttons includes two support plates, with a flip frame between the two support plates. Two positioning frames are slidably connected inside the flip frame. Two electric push rods are installed on the inner wall of the flip frame. The output end of each electric push rod is connected to one side of a positioning frame. Each positioning frame has a hexagonal clamp inside, and different types of positioning grooves are formed on the outer surface of each hexagonal clamp. Connecting shafts are fixedly connected to both ends of each hexagonal clamp. Connecting grooves are formed inside each positioning frame, and both ends of the two connecting shafts are rotatably connected to the connecting grooves. Equally spaced limiting grooves are formed on the outer surface of each connecting shaft. Threaded holes are formed on the upper surface of each positioning frame, and limiting screws are threaded into the interior of each threaded hole.

[0007] As a further technical solution of this utility model, the inner wall of the flipping frame is provided with two sliding grooves, and a slider is slidably connected inside each sliding groove. The sides of the two sets of sliders that are close to each other are connected to the outer surface of the positioning frame.

[0008] As a further technical solution of this utility model, each of the threaded holes is connected to the connecting groove, and the bottom end of each of the limiting screws is in contact with the inner wall of one of the limiting grooves.

[0009] As a further technical solution of this utility model, the left and right sides of the flipping frame are fixedly connected with rotating shafts, and one end of each rotating shaft is rotatably connected to the support plate through a bearing. A flipping motor is installed on one side of one of the support plates, and the output end of the flipping motor is connected to one end of the rotating shaft.

[0010] As a further technical solution of this utility model, the bottom surfaces of the two support plates are fixedly connected to a base, and the upper surface of the base is provided with two sets of mounting holes.

[0011] As a further technical solution of this utility model, a controller is installed on the outer surface of the support plate, and the controller is electrically connected to the electric push rod and the flipping motor respectively through wires.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device employs a rotatable hexagonal clamp with different types of positioning grooves on its six outer surfaces. One hexagonal clamp can provide six different positioning schemes, adapting to various models, sizes, and shapes of mobile phone buttons (such as volume buttons, power buttons, and home buttons). By rotating the clamp to change surfaces, the processing object can be quickly switched, greatly reducing the frequency of clamp changes and the number of dedicated clamps, significantly reducing equipment costs and production management complexity. The positioning frame is moved by an electric push rod, achieving automatic centering and clamping of the workpiece. The clamping force is uniform and precise, avoiding errors and uncertainties caused by human operation. The hexagonal clamp, through the cooperation of the limiting grooves and limiting screws at both ends of the connecting shaft, can achieve rigid locking after each surface is rotated into position, ensuring that the clamp will not rotate or shift during processing, thereby guaranteeing positioning accuracy and processing stability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this utility model, a positioning fixture for processing mobile phone buttons includes two support plates 1, with a flip frame 9 between the two support plates 1. Two positioning frames 6 are slidably connected inside the flip frame 9. Two electric push rods 8 are installed on the inner wall of the flip frame 9. The output end of each electric push rod 8 is connected to one side of the positioning frame 6. The positioning frame 6 is moved by the electric push rod 8, realizing automatic centering and clamping of the workpiece. The clamping force is uniform and precise, avoiding errors and uncertainties caused by human operation. Two sliding grooves 7 are opened on the inner wall of the flip frame 9. A slider 4 is slidably connected inside each sliding groove 7. The sides of the two sets of sliders 4 that are close to each other are connected to the outer surface of the positioning frame 6. The positioning frame 6 can be moved stably by the sliding grooves 7 and sliders 4. The clamping force of the fixture is evenly applied to the positioning frame 6 by the electric push rods 8, rather than directly acting on the delicate surface of the button itself. The reasonable structural design avoids direct rigid contact with the easily damaged areas of the product, greatly reducing the risk of scratching or crushing the product surface during clamping and processing.

[0021] Each positioning frame 6 has a hexagonal clamp 5 inside, and each hexagonal clamp 5 has different types of positioning grooves 16 on its outer surface. Each hexagonal clamp 5 has a connecting shaft 17 fixedly connected to both ends. Each positioning frame 6 has a connecting groove 14 inside. Using a rotatable hexagonal clamp 5, each of its six outer surfaces has different types of positioning grooves 16. One hexagonal clamp 5 can provide six different positioning schemes, adapting to various models, sizes, and shapes of mobile phone buttons. By rotating the clamp, the processing object can be quickly switched, greatly reducing the frequency of clamp changes and the number of dedicated clamps. Both ends of the two connecting shafts 17 are connected to... The connecting groove 14 is rotatably connected. Each connecting shaft 17 has equidistantly arranged limiting grooves 18 on its outer surface. Each positioning frame 6 has a threaded hole 15 on its upper surface. Each threaded hole 15 is threaded with a limiting screw 13. Each threaded hole 15 is connected to the connecting groove 14. The bottom end of each limiting screw 13 is in contact with the inner wall of one of the limiting grooves 18. The hexagonal clamp 5 can be rigidly locked after each face is rotated into position by the limiting grooves 18 and the limiting screws 13 at both ends of the connecting shaft 17. This ensures that the clamp will not rotate or shift during the processing, thereby ensuring positioning accuracy and processing stability.

[0022] The left and right sides of the flip frame 9 are fixedly connected with rotating shafts 12. One end of each rotating shaft 12 is rotatably connected to the support plate 1 through a bearing. One side of one of the support plates 1 is equipped with a flip motor 3. The output end of the flip motor 3 is connected to one end of the rotating shaft 12. The outer surface of the support plate 1 is equipped with a controller 10. The controller 10 is electrically connected to the electric push rod 8 and the flip motor 3 through wires. This utility model integrates the electric push rod 8 and the flip motor 3 and centrally controls them through the controller 10. The entire clamping, flipping and changing operation can be automated or semi-automated. The unique design of the flip frame 9 allows the fixture to be driven to rotate 180° after one side is processed, so that the workpiece on the other side can be processed immediately. This greatly reduces manual operation links and labor intensity. The clamping speed is fast and the production efficiency is high. The bottom surfaces of the two support plates 1 are fixedly connected to the base 2. The upper surface of the base 2 is provided with two sets of mounting holes 11. The base 2 and the mounting holes 11 cooperate to facilitate the installation and fixation of the positioning furniture.

[0023] The working principle of this utility model is as follows: When in use, the positioning fixture is installed in the usage position through the base 2, the power supply of the positioning fixture is turned on, and the two electric push rods 8 in the flip frame 9 are started synchronously by the controller 10. The electric push rods 8 drive the two positioning frames 6 to cooperate with the hexagonal clamp 5 to clamp the button. The hexagonal clamp 5 is set in the positioning frame 6, and its six outer surfaces are respectively provided with different types of positioning grooves 16. One hexagonal clamp 5 can provide six different positioning schemes, which can be adapted to mobile phone buttons of various models, sizes and shapes. By rotating the face, the processing object can be quickly switched. The hexagonal clamp 5 cooperates with the limiting grooves 18 at both ends of the connecting shaft 17 and the limiting screws 13 to achieve rigid locking after each face is rotated into place, ensuring that the fixture will not rotate or move during the processing.
