Description

Technical Field

[0001] This utility model relates to the field of backlight manufacturing process assembly technology, and in particular to a fixture with a hollow structure. Background Technology

[0002] As smartphones become increasingly complex and quality requirements rise, assembly processes also face higher demands. Traditional assembly turntables use acrylic steel plates as fixtures.

[0003] Traditional assembly turntable product placement fixtures are technically based on a combination of three parts: an upper transparent acrylic section, a middle steel plate, and a lower transparent acrylic section. The middle steel plate and the upper and lower acrylic sections are arranged in a grid pattern. Over long-term use, the upper and lower acrylic sections are prone to scratches, leading to abnormal camera gripping and affecting the film adhesion accuracy. Furthermore, the connection between the acrylic and the steel plate is susceptible to wear, which can transfer foreign matter and cause backlight defects, increasing repair costs and posing potential quality risks to customers. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings in the existing technology, and to propose a fixture with a hollow structure, wherein the fixture for assembling turntable products is changed to a hollow design on both the head and tail sides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixture with a hollow structure, including a tool, wherein hollow holes are provided on both sides of the tool, and a central plate is provided between the hollow holes distributed along both sides, and the central plate and the tool are integrally formed.

[0006] The device has through holes 1 on both the left and right sides. There are two through holes 1 on one side of the displacement device, and they are symmetrically distributed. There is a through hole 2 between the two through holes 1 distributed on one side. The through hole 2 penetrates the interior of the device. Both through holes 1 and through holes 2 are perpendicular to the device.

[0007] The device has through holes three at both ends. Two through holes three distributed along one end are symmetrically distributed with respect to the central plate. The through holes three are perpendicular to the device.

[0008] The center plate has a through hole four that runs through it, and the through hole four is horizontally positioned with the appliance.

[0009] The innovation of this solution is that the appliance is made of stainless steel, eliminating the traditional upper and lower transparent acrylic structure (such as the three-piece design mentioned in the background art), and only retaining the central plate (cross structure) in the middle, thereby avoiding wear and foreign matter caused by long-term friction between acrylic and steel plate (such as the adverse problems mentioned in the background art).

[0010] This fixture fundamentally solves the quality problems caused by acrylic wear in traditional designs through its hollow structure and material reduction. The fixture is a rectangular stainless steel structure with hollow holes on both sides and through holes at the front and rear ends forming a symmetrical distribution. This not only reduces weight but also facilitates visual positioning during assembly (such as camera gripping points). The integrated cross design of the center plate replaces the traditional grid-shaped hollow combination, avoiding the friction risk caused by connecting multiple parts. The overall solution eliminates the generation of foreign objects through structural simplification and material upgrades, while improving assembly accuracy and efficiency.

[0011] In detail, the device has a rectangular structure and is made of stainless steel.

[0012] In detail, the central plate has a cross-shaped structure.

[0013] In detail, the diameter of the second via is much smaller than the diameter of the first via.

[0014] In detail, the surface of the central plate is provided with a number of through holes five that penetrate its interior, and the through holes five are symmetrically distributed along the front and rear ends of the central plate.

[0015] In detail, the central area of ​​the central plate is provided with several through holes six that penetrate through it, and the diameter of the through holes six is ​​much smaller than the diameter of the through holes five.

[0016] In detail, the central area of ​​the central plate has a central hole that penetrates through it, and a number of through holes are arranged in a ring around the central hole.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] This solution provides a fixture with open top and bottom sections, eliminating the transparent acrylic at the top and bottom, reducing the risk of membrane material misalignment during assembly, improving assembly accuracy, and eliminating friction between acrylic and steel plate, fundamentally preventing the generation of wear and foreign objects, thereby improving yield. In addition, the original middle steel plate has a cross-shaped structure, and the upper and lower parts of the cross steel are widened and lengthened to make the product placement more stable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 A fixture with a hollow structure includes a fixture 1, with hollow holes 14 on both sides of the fixture 1, and a central plate 19 between the hollow holes 14 distributed along both sides. The central plate 19 and the fixture 1 are integrally formed.

[0027] Both sides of the device 1 have through holes 11. There are two through holes 11 distributed on one side of the displacement device 1, and they are symmetrically distributed. There is a through hole 2 12 between the two through holes 11 distributed on one side. The through hole 2 12 penetrates the interior of the device 1. Both through holes 11 and through holes 2 12 are perpendicular to the device 1.

[0028] Both ends of the appliance 1 have through holes 3 13. Two through holes 3 13 distributed along one end are symmetrically distributed with respect to the central plate 19. The through holes 3 13 are perpendicular to the appliance 1. Both ends of the appliance 1 located at the hollow hole 14 have indentations, and the through holes 3 13 are located in the indentations.

[0029] The center plate 19 has a through hole 4 15 that runs through it, and the through hole 4 15 is horizontally positioned with the appliance 1.

[0030] It should be further noted that the device 1 has a rectangular structure and is made of stainless steel. The traditional upper and lower transparent acrylic parts are eliminated, and only the middle stainless steel part is retained. This reduces the risk of membrane material misalignment during assembly, improves assembly accuracy, eliminates friction between acrylic and steel plate, and fundamentally prevents the generation of wear foreign objects, thereby improving yield.

[0031] It should be further noted that the center plate 19 has a cross structure, and the upper and lower parts of the cross structure are widened and lengthened to make the product more stable when placed.

[0032] It should be further noted that the diameter of via hole 2 12 is much smaller than the diameter of via hole 11. Via hole 11 is used to reduce the overall weight and facilitate the installation and fixation of the fixture. Via hole 2 12 is used to assist in positioning or reduce weight, while avoiding affecting the structural strength.

[0033] It should be further explained that the surface of the center plate 19 is provided with a number of through holes 16 penetrating its interior. The through holes 16 are symmetrically distributed along the front and rear ends of the center plate 19, and the single-layer through holes 16 are distributed in a 2*4 pattern.

[0034] It should be further noted that the central area of ​​the central plate 19 has several through holes 17 that penetrate its interior. The diameter of the through holes 17 is much smaller than that of the through holes 16. The several through holes 17 are arranged in a cross shape.

[0035] It should be further noted that a central hole 18 is provided in the central area of ​​the central plate 19, and several through holes 17 are arranged in a ring around the central hole 18. The central hole 18 can be easily connected to the shaft used for the rotation of the turntable.

[0036] In practice

[0037] The appliance 1 in this solution is made of stainless steel and eliminates the traditional upper and lower transparent acrylic structure (such as the three-piece design mentioned in the background art). Only the central plate 19 (cross structure) is retained, thereby avoiding wear and foreign matter caused by long-term friction between acrylic and steel plate (such as the adverse problems mentioned in the background art).

[0038] The cross structure of the center plate 19 is widened and lengthened at the top and bottom to enhance the stability of product placement. In addition, the design of the hollow holes 14 and through holes 11 on both sides not only reduces the overall weight but also facilitates the installation and fixation of the fixture. Through holes 12, as auxiliary positioning holes, have a smaller diameter, which reduces weight while ensuring structural strength. Through holes 16 and 17 on the center plate 19 further optimize the weight distribution. At the same time, the design of the center hole 18 facilitates connection with the turntable shaft, ensuring the stability of the fixture during rotation. These improvements work together to significantly reduce the risk of membrane assembly misalignment and improve yield.

[0039] This fixture fundamentally solves the quality problems caused by acrylic wear in traditional designs by using a hollow structure and reducing materials. The fixture 1 is a rectangular stainless steel structure with hollow holes 14 on both sides and through holes 13 at the front and rear ends forming a symmetrical distribution. This not only reduces weight but also facilitates visual positioning during assembly (such as camera gripping points). The integrated cross design of the center plate 19 replaces the traditional grid-shaped hollow combination, avoiding the friction risk caused by connecting multiple parts. The overall solution eliminates the generation of foreign objects through structural simplification and material upgrades, while improving assembly accuracy and efficiency.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
