Description

Technical Field

[0001] This utility model relates to the field of display module assembly fixture technology, and more specifically, to a display module frame assembly positioning fixture. Background Technology

[0002] Display module bezel assembly is the process of precisely assembling the display assembly and bezel into a complete product. To ensure the accuracy of the assembly, the workpiece needs to be fixed by positioning fixtures during the assembly process to carry out the assembly operation without deviation.

[0003] Currently, the fixture has a complex structure and a small internal operating space. Employees need to be very careful when picking up or placing frames or modules, or they need to make multiple adjustments before they can be put in. This can easily scratch the workpiece and affect the overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a display module frame assembly and positioning fixture, which solves the problem that display modules are difficult to operate in the narrow space of the fixture in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A display module bezel assembly and positioning fixture includes a base and a rotating bidirectional fixture above it;

[0007] The base is fixedly mounted with brackets at both ends, and the front and rear center ends of the rotary bidirectional clamp are rotatably mounted inside the brackets.

[0008] The rotary bidirectional clamp includes a rotating frame and a tray.

[0009] The rotating frame has a double-opening structure at the top and bottom, and the tray is detachably installed on one side of the opening of the rotating frame;

[0010] The center of the tray is provided with a circular pad that can be elastically arched.

[0011] The rotating frame is provided with longitudinal bidirectional clamping mechanisms at both ends, including two bidirectional transmission rods with opposite rotation directions at the top and bottom.

[0012] The outer side of the bidirectional transmission rod is provided with a clamping arm;

[0013] The pallet has openings at both ends, which cover the bidirectional clamping mechanism.

[0014] Preferably, a fixing plate is fixed at the lower end of the center of the tray, and a movable top block is provided above the fixing plate.

[0015] Preferably, spring telescopic rods are evenly distributed around the top block above the fixed plate, and each end of the spring telescopic rod is fixed with a rotating seat, which is rotatably connected to the top block and the side wall of the fixed plate, respectively.

[0016] Preferably, the outer side of the bidirectional transmission rod is connected to a swivel sleeve, and one end of the clamping arm is fixed with a rotating frame, which is rotatably mounted on the outer side of the swivel sleeve.

[0017] Preferably, a support block and a base are fixedly installed at the corners of the tray and the rotating frame, respectively.

[0018] Preferably, a support rod extends from the upper end of the support block, and an elastic pad surrounds the outside of the support rod.

[0019] Preferably, the support has a through hole running vertically through the interior, and the inner wall of the through hole has an arc-shaped groove corresponding to the elastic pad.

[0020] The beneficial effects of this utility model are:

[0021] 1. By installing a deformable circular pad in the center of the tray and setting an elastic lifting mechanism below it, a lifting force can be generated when the display module assembly is placed. If there is no external force intervention, it can be pushed out in time to facilitate the adjustment of its position. There is no need to worry about scratches or inconvenience in operation in narrow spaces, thus shortening the overall working time.

[0022] 2. Through the double-opening structure and bidirectional clamping mechanism of the rotating frame, the working area of ​​the tray can be easily changed, and the upper and lower working openings of the rotating frame can be reversed, which facilitates the assembly of different sides of the display module.

[0031] 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.

[0032] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] A display module frame assembly and positioning fixture is designed to facilitate the positioning and assembly of the display module. The top block 35 is automatically raised by the spring telescopic rod 36, and the display module is supported by the arch of the circular pad 32. The display module can be removed in time for position adjustment, and then pressed and fixed after adjustment.

[0034] In addition, the bidirectional clamping mechanism allows for quick switching of the working surface of the rotating frame 2, facilitating the assembly of different surfaces of the display module and the frame.

[0035] In some embodiments, the specific structure of the display module frame assembly positioning fixture is as follows: Figure 1-5 As shown, it includes a base 1 and a bidirectional clamp above it;

[0036] The base 1 has brackets 11 fixedly installed on both sides. One of the brackets 11 has a rotary motor installed inside, which is fixedly connected to the rotating shafts at both ends of the bidirectional clamp to drive the bidirectional clamp to rotate and switch the working surface.

[0037] A two-way clamp, comprising a rotating frame 2 and a tray 3;

[0038] The rotating frame 2 has a double-opening structure at the top and bottom, and the tray 3 is detachably installed on one side opening of the rotating frame 2 to form a one-way closed structure.

[0039] Among them, a circular pad 32 and a fixing plate 34 are fixedly installed on the upper and lower sides of the center of the tray 3, forming a hollow cavity between them;

[0040] Furthermore, a top block 35 is placed in the cavity, the upper surface of which is arc-shaped, and multiple spring telescopic rods 36 are evenly distributed on the outer side of the top block 35. The upper and lower ends of the spring telescopic rods 36 are rotatably connected to the top block 35 and the side wall of the fixing plate 34, respectively.

[0041] It is understandable that the spring telescopic rod 36 can drive the top block 35 to rise through its elastic extension and contraction, thereby periodically causing the circular pad 32 to arch, which in turn pushes the display module upward, making it easier to adjust its position for secondary placement.

[0042] The two ends of the pallet 3 are provided with a bidirectional clamping mechanism in the vertical direction, including a bidirectional transmission rod 22;

[0043] The bidirectional transmission rod 22 is fixedly connected to the rotating frame 2 through the block structure of the middle section. The upper and lower sections of the body are ball screws with opposite rotation directions, and each of them is screwed with a screw sleeve 221.

[0044] The outer side of the screw-fit sleeve 221 is provided with a coaxially rotating clamping arm 23. An electric telescopic device is installed on one side of the clamping arm 23, and a rubber pad is installed on its movable end to clamp the display module frame to form a clamping fixation.

[0045] It is understandable that when the bidirectional clamping mechanism clamps the display module frame, the tray 3 can be removed and installed on the other side of the rotating frame 2. The working surface can be switched by rotating the rotating frame 2, which facilitates the assembly of different surfaces.

[0046] It should be noted that when the display module is adjusted to the predetermined position, the two-way clamping mechanism can prevent the spring telescopic rod 36 from pushing the display module out again.

[0047] like Figure 2 As shown in Figure 4, support blocks 33 and supports 21 of the same shape are installed at the corners of the pallet 3 and the rotating frame 2, respectively.

[0048] Among them, a support rod 331 is fixedly installed on one side of the support block 33, and an elastic pad 3311 is fixed around the outside of the support rod 331.

[0049] It should be noted that the elastic pad 3311 is preferably made of elastic silicone rubber, which can produce corresponding elastic deformation under pressure.

[0050] Furthermore, the support 21 has a through hole 211 coaxial with the support rod 331 inside, and the inner wall of the through hole 211 has multiple upper and lower arc grooves 2111, corresponding to the elastic pad 3311.

[0051] It is understandable that when the support rod 331 is inserted into the through hole 211, it fills the arc groove 2111 through the elastic deformation of the elastic pad 3311 to form a snap-fit ​​fixation, thereby fixing the support plate 3 to one side of the rotating frame 2.

[0052] like Figure 5 As shown, rotating seats 361 are fixedly installed at both ends of the spring telescopic rod 36, and a through hole is opened in the center of the rod, which is rotatably connected to the bearing installed on the outer side of the top block 35 and the inner surface of the side wall of the fixed plate 34.

[0053] Understandably, when the pressure above the circular pad 32 disappears, the spring telescopic rod 36 is in its normal state, that is, extended to the tilted state, at which time the top block 35 pushes the circular pad 32 upward.

[0054] like Figure 3 As shown, a rotating frame 231 is fixedly installed at the other end of the clamping arm 23, and the rotating frame 231 is rotatably installed on the outside of the screw-on sleeve 221;

[0055] The pallet 3 has openings 31 at both ends, which cover the bidirectional clamping mechanism.

[0056] Understandably, by rotating the clamping arm 23 to adjust the position of its end electric telescopic device, the relative position of the clamping display module frame can be adjusted.

[0057] Some publicly available information shows the specific usage method of the module frame assembly positioning fixture as follows:

[0058] S1. When placing the display module on the circular pad 32, first apply downward pressure to fix the display module. Then observe whether the position is accurate. If it is accurate, fix it through the bidirectional clamping mechanism. If it is inaccurate, release the downward pressure and use the elasticity of the spring telescopic rod 36 to drive the top block 35 to rise and periodically move the circular pad 32, thereby lifting the display module to achieve the removal effect. At this time, the position can be directly adjusted and placed a second time until the placement position is accurate.

[0059] S2. After the display module is accurately positioned, place the frame and then fix it using a two-way clamping mechanism;

[0060] S21. To use the bidirectional clamping mechanism, first rotate the screw-on sleeve 221 and use its transmission connection with the bidirectional transmission rod 22 to move it closer to the rotating frame 2.

[0061] Then rotate the clamping arm 23 so that its movable end swings to the predetermined position;

[0062] Finally, the electric telescopic device at the movable end of the clamping arm 23 presses down on the rubber pad, thereby clamping and fixing the display module frame.

[0063] S3. After the assembly work on one side is completed, pull down the tray 3 to disengage the support rod 331 from the through hole 211. Then, place the tray 3 in reverse above the rotating frame 2 and insert the support rod 331 into the through hole 211. The elastic pad 3311 and the arc groove 2111 are used to form a fixed connection. Then, the rotating frame 2 is rotated 180° by the rotating motor in the bracket 11, thereby achieving the effect of switching the working surface.

[0064] S4. Finally, release the two-way clamping mechanism from the frame of the real module and remove the finished product.
