Technical Field

[0001] The present invention relates to the technical field of mobile phone processing, and in particular to a mobile phone middle frame flipping mechanism. Background Art

[0002] The flip mechanism of the mobile phone frame is an innovative technology designed to change the appearance and function of the mobile phone. With the continuous increase of smartphone functions and the intensification of competition, mobile phone manufacturers strive to seek new design concepts and functional innovations to attract consumers' attention. The emergence of the flip mechanism of the mobile phone frame has brought new possibilities to mobile phone design. The flip mechanism of the mobile phone frame is usually realized by a mechanical structure or an electric mechanism, which allows the frame of the mobile phone to be flipped or rotated in different directions. This design allows users to use the mobile phone more conveniently in different scenarios. For example, when taking selfies, the frame of the mobile phone can be flipped to the front, making it more convenient to take pictures; when watching videos or playing games, the frame of the mobile phone can be flipped to the horizontal direction to provide a better viewing experience. The background of the flip mechanism of the mobile phone frame can be traced back to the continuous pursuit of user experience and functional requirements.

[0003] As people's requirements for mobile phone functions and appearance design become higher and higher, mobile phone manufacturers continue to develop new technologies and designs to meet user needs.

The mobile phone middle frame flipping mechanism in the above invention has the following shortcomings:

[0005] Although the above device effectively solves the problems of poor positioning accuracy, low work efficiency, high labor intensity of workers and high labor costs for enterprises caused by the traditional manual operation of flipping and positioning the middle frame of the mobile phone, the guide rail assembly, lifting cylinder, rotating cylinder and clamp cylinder require a complete pneumatic control system to complete the coordinated work, resulting in increased basic cost and maintenance cost, and the control and positioning of the above pneumatic components will be limited by high precision requirements. Therefore, a mobile phone middle frame flipping mechanism is urgently needed. Summary of the invention

[0009] The top of the mobile flip mechanism is clamped with the mobile phone middle frame body, one end of the screw rod is connected to the guide shaft through a thread, the circumferential outer wall of the guide shaft is connected to the secondary gear through a thread, and the circumferential teeth of the secondary gear are meshed with the main gear, and one side of the fixed plate 2 is fixedly connected to a bracket, one side of the bracket is fixed with a motor through bolts, and the output end of the motor is connected to the main gear through a thread.

[0010] Preferably: the mobile flip mechanism includes a fixed component, a mobile plate, a linkage gear, a rack plate, an opening, a guide component, a U-shaped groove and a mobile channel, and the fixed component is clamped in the middle of the bottom of the mobile phone middle frame body, and the two ends of the mobile plate are fixedly connected to the opposite sides of the two sliding blocks.

[0011] Furthermore: the U-shaped groove is opened on one side of the bottom of the second fixed plate, and the movable channel is arranged on the inner wall of the second fixed plate close to the top of the U-shaped groove, and the opening is opened at one end of the movable channel, and the guide component is limitedly slidably connected in the U-shaped groove and the movable channel.

[0012] On the basis of the above scheme: the linkage gear is connected to the bottom end of the guide assembly through threads, the rack plate is fixedly connected to the bottom of the fixed plate 1, and the rack plate and the linkage gear are meshed with each other.

[0013] The starting motor drives the screw to rotate, and the rotating screw drives the moving plate and the sliding blocks at both ends of the moving plate to slide horizontally and linearly in the sliding grooves in the mounting plate one and the mounting plate two. During the movement of the moving plate, the guide assembly moves together with the mobile phone middle frame body from the U-shaped groove and the moving channel in the fixed plate two. At the same time, the linkage gear at the bottom of the guide assembly also moves accordingly. When the linkage gear moves and engages with the rack plate at the bottom of the fixed plate one, it drives the mobile phone middle frame body to flip over, and the flip angle is zero to one hundred and eighty degrees, thereby effectively realizing the rapid flipping of the mobile phone middle frame body.

[0014] A better solution among the above-mentioned solutions is: the guiding assembly includes a guide wheel, a mounting ring, a rotating rod, a connecting plate, a guide plate and an L-shaped limiting plate, and the bottom end of the rotating rod is threaded on the inner circumference of the linkage gear, the mounting ring is limitedly slidably connected in the moving channel, and the mounting ring and the rotating rod are interlaced.

During the movement of the moving plate, the guide assembly moves together with the mobile phone middle frame body from the U-shaped groove and the moving channel in the fixed plate 2. At the same time, the linkage gear at the bottom end of the guide assembly also moves accordingly. When the linkage gear moves and engages with the rack plate at the bottom of the fixed plate 1, the mobile phone middle frame body is driven to flip, and the flipping angle is zero to one hundred and eighty degrees, which effectively realizes the rapid flipping of the mobile phone middle frame body and is conducive to the adjustment of the flipping angle during the processing of the mobile phone middle frame body, solves the disadvantages of using various pneumatic components to flip the mobile phone middle frame body in the prior art, not only can it reduce the basic cost and maintenance cost, but also compared with the prior art, no pneumatic control system is used, thereby improving the efficiency and quality of the flipping of the mobile phone middle frame body.

[0023] 2. A mobile phone middle frame flipping mechanism, when the moving plate moves, drives the mounting ring to move in the U-shaped groove and the moving channel, and at the same time the guide wheel rolls in the moving channel, and when the linkage gear is engaged with the rack plate, drives the rotating rod to rotate, and drives the guide plate on the top of the rotating rod to rotate, thereby promoting the flipping of the mobile phone middle frame body on the top of the guide plate, which not only promotes the stable movement and delivery of the mobile phone middle frame body to the designated processing station, but also reduces the number of times the workpiece is moved, reduces the need for manual intervention, and ensures that each surface of the mobile phone middle frame body can be evenly processed.

[0024] 3. A mobile phone middle frame flipping mechanism first adsorbs one side of the bottom of the mobile phone middle frame body to the top of the T-shaped guide rod through a magnetic suction sheet, and inserts the four corners of the top of the T-shaped guide rod into the L-shaped step clamping plate accordingly, so that the four L-shaped step clamping plates clamp the two sides of the bottom of the mobile phone middle frame body, thereby promoting the movement and flipping stability of the mobile phone middle frame body. At the same time, the mobile phone middle frame body is flipped 90 degrees, so that the mobile phone middle frame body rotates around the rotating axis, and after the mobile phone middle frame body is flipped, it can be supported by the L-shaped limit plate, thereby realizing the horizontal flipping of the mobile phone middle frame body, which is convenient for subsequent processing.
