[0002] The LCD module frame is an industrial product. An LCD is constructed by placing liquid crystals between two parallel glass plates. Numerous fine vertical and horizontal wires connect the two glass plates, controlling the orientation of rod-shaped crystal molecules by adjusting the flow of electricity, thus refracting light to create an image. During manufacturing, the front frame needs to be fixed to facilitate drilling and other fabrication processes.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a fixing fixture for an LCD frame, including:

[0035] Please see Figures 1-5 This embodiment of an LCD frame fixing fixture includes a worktable 100. The worktable 100 has a moving component 200 in its inner cavity. The moving component 200 includes a moving frame 230 and a moving part 250. The top of the moving part 250 is provided with a clamping component 300, which includes a spring 330 and a buffer plate 350.

[0036] It is worth noting that, in order to facilitate the movement of the clamping component 300, a frame plate 110 is placed on the top of the worktable 100, and four square through slots are opened on the top of the worktable 100 to facilitate the movement of the connecting block.

[0037] Next, in order for the moving component 200 to drive the clamping component 300 to move, specifically, the moving component 200 includes a main rod 210, with multiple moving frames 230 sleeved on the outer circumference of the main rod 210. The main rod 210 controls the movement of the clamping component 300 in the Y-axis direction. A secondary rod 240 is inserted into the side wall of the moving frame 230, with multiple moving parts 250 sleeved on the outer circumference of the secondary rod 240. The secondary rod 240 controls the movement of the clamping component 300 in the X-axis direction.

[0038] Meanwhile, in order for the clamping assembly 300 to clamp the fixed frame plate 110, specifically, the clamping assembly 300 includes a clamping block 310. The clamping block 310 has multiple insertion holes on its side wall. A telescopic rod 320 is inserted into the insertion hole. A spring 330 is sleeved on the outer circumference of the telescopic rod 320 to reduce the pressure of the clamping assembly 300 on the frame plate 110. A fixing plate 340 is welded to the side wall of the spring 330 and the side wall of the telescopic rod 320. A buffer plate 350 is adhered to the side wall of the fixing plate 340 to avoid rigid contact of the fixing plate 340 causing damage to the surface of the frame plate 110.

[0039] Furthermore, for ease of control of the moving component 200, specifically, a baffle 251 is integrally formed on the top of the moving component 250. The baffle 251 is used to cover the square through slot, reducing the amount of dust entering the workbench 100. A connecting block is integrally formed on the top of the baffle 251. The clamping block 310 is fixedly connected to the top of the connecting block by screws. A limit sleeve is sleeved on the outer circumference of the main rod 210 to limit the moving frame 230 and prevent impact damage. A left thread is opened on the outer circumference of one end of the main rod 210 and the auxiliary rod 240, and a right thread is opened on the outer circumference of the other end of the main rod 210 and the auxiliary rod 240. The bidirectional threads enable bidirectional movement between the two moving frames 230 and the four moving components 250, causing the clamping component 300 to retract inward or expand outward. A threaded hole matching the outer circumference of the auxiliary rod 240 is opened at the bottom of the moving component 250 to facilitate the movement of the moving component 250.

[0040] It is worth noting that, in order to facilitate the control of the rotation of the main rod 210 and the auxiliary rod 240, specifically, a handle 211 is welded to the side wall of the main rod 210 through the worktable 100, a handle 241 is welded to the side wall of the auxiliary rod 240 through the worktable 100, and multiple sliding rods 220 are inserted into the bottom of the moving frame 230 to enhance the support of the moving frame 230 in conjunction with the main rod 210.

[0041] Finally, in order to reduce the pressure on the contact surface between the clamping assembly 300 and the frame plate 110, specifically, the clamping block 310 has an L-shaped structure, which facilitates clamping and fixing the four corners of the frame plate 110. The buffer plate 350 is a rubber plate, and the fixing plate 340 is a memory metal plate. The fixing plate 340 and the buffer plate 350 work together to effectively reduce the pressure on the contact surface.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of the LCD frame fixing fixture of this embodiment is as follows:

[0044] 1: When using the fixed fixture, place the frame plate 110 on top of the workbench 100 and center its position, then control the moving component 200 through handle 1 211 and handle 2 241.

[0045] 2: Rotating handle 211 causes the main rod 210 to rotate. Because of the bidirectional thread on the outer circumference of the main rod 210, the two moving parts 230 move in opposite directions. Then, control handle 241 to rotate, causing the auxiliary rod 240 to rotate. Because of the bidirectional thread on the outer circumference of the auxiliary rod 240, the two moving parts 250 move in opposite directions, so that the clamping assembly 300 can be adjusted in both directions on the XY axis.

[0046] 3: When the clamping assembly 300 contacts the frame plate 110, the buffer plate 350 and the fixing plate 340 are in close contact with the side wall of the frame plate 110. Then, the buffer plate 350 will work with the spring 330 to buffer part of the pressure. The telescopic rod 320 will extend and retract due to the elastic deformation of the spring 330, thereby controlling the lateral displacement of the fixing plate 340 and the buffer plate 350, reducing the pressure on the contact surface between the clamping assembly 300 and the frame plate 110, and avoiding damage to the surface of the frame plate 110 when the clamping assembly 300 clamps the fixed frame plate 110, thus effectively reducing the damage rate of the frame plate 110.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
