Description

Technical Field

[0001] This utility model relates to the field of mobile phone mid-frame processing technology, specifically to a layered mobile phone mid-frame spraying fixture. Background Technology

[0002] The mobile phone mid-frame spraying fixture is a clamp specifically designed to fix and mask the mobile phone mid-frame during the spraying process. Through a reasonable structure design, the spraying fixture firmly fixes the mobile phone mid-frame on the fixture, preventing it from moving or falling off during the spraying process, and ensuring the accuracy and consistency of the spraying.

[0003] Existing mobile phone frame coating fixtures typically use screws to clamp and fix the mobile phone frame, which cannot achieve rapid clamping of the mobile phone frame and results in low clamping efficiency. Before coating, workers need to manually or use tools to tighten each screw one by one, which is not only time-consuming and labor-intensive, but also increases the complexity of the operation. On large-scale, high-efficiency production lines, this inefficient clamping method will undoubtedly become a bottleneck restricting production speed. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a layered mobile phone mid-frame spraying fixture.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A layered mobile phone mid-frame spraying fixture includes:

[0007] Placement board;

[0008] Two grooves are respectively formed at both ends of the placement plate;

[0009] Two sliding plates are respectively sealed and slidably connected within two sliding grooves;

[0010] Two clamping blocks are respectively fixed to the ends of the two sliding plates that are far apart from each other;

[0011] Two springs, one end of which is connected to the wall of the two grooves respectively, and the other end of which is connected to the two slide plates respectively;

[0012] The outer cylinder is positioned below the placement plate;

[0013] An inner rod is slidably disposed inside the outer cylinder, with its top end extending to the outside of the outer cylinder and fixedly connected to the placement plate;

[0014] An inflatable structure is provided on the inner rod;

[0015] The positioning structure is installed on the outer cylinder and the inner rod.

[0016] As a further embodiment of this utility model: the inflatable structure includes:

[0017] A cavity is formed inside the inner rod;

[0018] The sliding plug is slidably connected to the cavity in a sealing manner.

[0019] The pressure rod has one end fixedly connected to the sliding plug and the other end extending to the outside of the cavity. The pressure rod passes through the bottom end of the inner rod and is slidably connected to the inner rod. The end of the pressure rod located outside the cavity is fixedly connected to the inner bottom surface of the outer cylinder.

[0020] Spring 2 has one end connected to the top of the cavity and the other end connected to the sliding plug;

[0021] Two connecting tubes, one end of which is connected to the cavity, and the other end of which is connected to two sliding plugs respectively.

[0022] As a further embodiment of this utility model: the positioning structure includes:

[0023] Both grooves are formed on the inner rod;

[0024] Two locking blocks are slidably disposed in the two grooves respectively, and each locking block is provided with a bevel.

[0025] Two springs, one end of which is connected to the groove wall of each of the two grooves, and the other end of which is connected to each of the two locking blocks;

[0026] Both bayonets are located on the outer cylinder.

[0027] As a further embodiment of this utility model, the inner surface of the outer cylinder and the outer surface of the inner rod are fitted together.

[0028] As a further embodiment of this invention, the clamping block is made of rubber material.

[0029] As a further aspect of this utility model, the shape of the card block is adapted to the card slot.

[0030] The beneficial effects of this utility model are:

[0031] 1. This fixture enables the quick clamping and disassembly of the mobile phone frame. The operator only needs to place the mobile phone frame on the placement plate and press it gently. Through a series of mechanical linkages, the two clamping blocks will press the mobile phone frame together to complete the fixation. In this process, no screws or other complicated tools are required, which greatly improves the clamping efficiency. At the same time, when it is necessary to remove the fixation, it is only necessary to press the two clips to easily and quickly disassemble the mobile phone frame, which also saves time and labor costs.

[0032] 2. This fixture employs multiple safeguards to ensure the stability and reliability of the phone's mid-frame during fixation. First, the two clamping blocks work together mechanically to provide a balanced and stable clamping force. Second, as the inner rod moves downward, the two locking blocks spring out under the force of the spring and engage in the locking slots, further securing the position of the inner rod. This ensures the fixation effect of the two sliding plates on the phone's mid-frame. This design not only improves the stability of the fixation but also effectively avoids painting quality problems caused by unstable fixation. Attached Figure Description

[0038] 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 scope of protection of the present utility model.

[0039] like Figure 1-3 As shown, a layered mobile phone frame spraying fixture includes a placement plate 1; two sliding grooves 2, respectively opened at both ends of the placement plate 1; two sliding plates 3, respectively sealed and slidably connected in the two sliding grooves 2; two clamping blocks 4, respectively fixed to the two sliding plates 3 at their opposite ends, the clamping blocks 4 being made of rubber material; two springs 5, one end of which is connected to the groove wall of the two sliding grooves 2, and the other end of which is connected to the two sliding plates 3; an outer cylinder 6, placed below the placement plate 1; an inner rod 7, slidably disposed in the outer cylinder 6, the top end of the inner rod 7 extending to the outside of the outer cylinder 6 and fixedly connected to the placement plate 1, the inner surface of the outer cylinder 6 and the outer surface of the inner rod 7 being in contact with each other;

[0040] The stacked mobile phone frame spraying fixture also includes an inflation structure, which is set on the inner rod 7. The inflation structure includes: a cavity 81, which is opened inside the inner rod 7; a sliding plug 82, which is slidably connected to the cavity 81; a pressure rod 83, one end of which is fixedly connected to the sliding plug 82, and the other end extends to the outside of the cavity 81. The pressure rod 83 passes through the bottom end of the inner rod 7 and is slidably connected to the inner rod 7. The end of the pressure rod 83 located outside the cavity 81 is fixedly connected to the inner bottom surface of the outer cylinder 6; a second spring 84, one end of which is connected to the top of the cavity 81, and the other end of which is connected to the sliding plug 82; and two connecting pipes, one end of which is connected to the cavity 81, and the other end of which is connected to the inner rod 6. Connected to the two sliding plugs 82, when the placement plate 1 moves down, it can drive the inner rod 7 to move down, so that the inner rod 7 retracts into the outer cylinder 6. During this process, the inner rod 7 and the pressure rod 83 move relative to each other, which makes the sliding plug 82 move in the cavity 81. When the sliding plug 82 moves, it can push the air in the cavity 81 into the two sliding grooves 2 through the two connecting pipes. When the gas enters the two sliding grooves 2, the gas can push the two sliding plates 3 to move, so that the two pressure plates move away from each other until the two pressing blocks 4 press the mobile phone frame together. At this time, the two sliding plates 3 together play a pressing and fixing role on the mobile phone frame, thus fixing the mobile phone frame on the placement plate 1.

[0041] The stacked mobile phone frame spraying fixture also includes a positioning structure, which is set on the outer cylinder 6 and the inner rod 7. The positioning structure includes: two grooves 91, both of which are opened on the inner rod 7; two locking blocks 92, which are slidably set in the two grooves 91 respectively, and each locking block 92 is provided with an inclined surface; two springs 93, one end of which is connected to the groove wall of the two grooves 91 respectively, and the other end of which is connected to the two locking blocks 92 respectively; and two latches 94, both of which are opened on the outer cylinder 6. The shape of the locking blocks 92 is adapted to the latches 94. When the inner rod 7 moves down, the two locking blocks 92 will move to the position directly opposite the two latches 94. At this time, the two locking blocks 92 will pop out under the elastic force of the two springs 93 and respectively lock into the two latches 94. At this time, the two locking blocks 92 and the two latches 94 together fix the position of the inner rod 7. When the inner rod 7 is fixed, the position of the sliding plug 82 in the cavity 81 is also fixed, and the position of the two sliding plates 3 is also fixed.

[0042] The working principle of this utility model:

[0043] When using the stacked mobile phone frame spraying fixture proposed in this utility model, the operator first places the mobile phone frame on the placement plate 1 and then presses the mobile phone frame, causing the mobile phone frame to move the placement plate 1 downward. When the placement plate 1 moves downward, it can move the inner rod 7 downward, causing the inner rod 7 to retract into the outer cylinder 6. During this process, there is a relative movement between the inner rod 7 and the pressure rod 83, which causes the sliding plug 82 to move in the cavity 81. When the sliding plug 82 moves, it can push the air in the cavity 81 into the two sliding grooves 2 through the two connecting pipes. When the gas enters the two sliding grooves 2, the gas can push the two sliding plates 3 to move, causing the two pressure plates to move away from each other until the two pressing blocks 4 press the mobile phone frame together. At this time, the two sliding plates 3 together play a role in pressing and fixing the mobile phone frame, thus fixing the mobile phone frame on the placement plate 1.

[0044] Additionally, when the inner rod 7 moves downwards, the two locking blocks 92 will move to positions directly opposite the two latches 94. At this time, the two locking blocks 92 will pop out under the elastic force of the two springs 93 and respectively lock into the two latches 94. The two locking blocks 92 and the two latches 94 together fix the position of the inner rod 7. When the inner rod 7 is fixed, the position of the slider 82 within the cavity 81 is also fixed, and the positions of the two sliding plates 3 are also fixed. This design ensures the fixation effect of the two sliding plates 3 on the phone's frame. To release the two sliding plates 3 from the phone... When fixing the middle frame, the staff can press the two clips 92 to retract the two clips 92 into the two grooves 91 respectively. When the inclined surfaces of the two clips 92 are retracted into the inner cylinder 6, the two clips 92 no longer provide a limit to the inner rod 7. At this time, the inner rod 7 will move upward and reset under the elastic force of the second spring 84, so that the sliding plug 82 moves downward in the cavity 81. When the sliding plug 82 moves downward, it can draw out the air in the two sliding grooves 2 through the two connecting pipes. This allows the two sliding plates 3 to reset under the action of the two springs 5, so that the middle frame of the mobile phone can be quickly disassembled.

[0045] Furthermore, staff can use brackets to stack several outer cylinders in six layers to achieve the stacking and clamping of the mobile phone frame.

[0046] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
