Description

Technical Field

[0001] This utility model relates to the field of backlight assembly technology, and in particular to a fixture for placing steel components for lamp guide detection. Background Technology

[0002] As the market and customers demand increasingly higher quality backlight products while prices continue to fall, the need for stricter control over the production process is also growing.

[0003] Traditional process for testing and placing steel fixtures for light guide components involves hollowing out the middle of the steel component, placing a glass block, and fixing it with screws. Gaps and height differences between the glass and the steel component can easily lead to defects such as scratches and white spots on the light guide plate.

[0004] For example, scratches, white spots, and white marks can lead to low product yield and increased rework costs. In addition, slight white marks can result in poor luminescence after assembly, which often leads to products being lost to customers, damaging the company's quality and reputation, and potentially reducing the company's market competitiveness. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings of the existing technology by proposing a lamp guide detection and placement steel fixture. By hollowing out the middle of the steel part and making the surrounding area low, and embedding the glass block in the inner groove, the continuous occurrence of defects is avoided from the source, thereby improving the yield.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lamp guide detection and placement steel fixture, including a steel fixture, wherein the interior of the steel fixture is provided with a hollow hole, both the steel fixture and the hollow hole are rectangular structures, an indentation is provided on the front of the steel fixture, and a notch is provided on the edge of the indentation to penetrate the edge of the steel fixture, the notch being distributed along the four apex positions of the indentation.

[0007] A glass plate, which is made of tempered glass, is inserted into the recessed area.

[0008] A mounting plate is welded and fixed to one side of the steel fixture. The mounting plates are symmetrically distributed along both sides of the steel fixture. Several mounting holes are opened on the surface of the mounting plates, and the mounting holes are arranged in the same row.

[0009] This solution utilizes an internal perforated design and a concave front to create a precise positioning space for the light guide assembly. The concave area is recessed and milled around its perimeter before a tempered glass plate is inserted. The glass's flatness and wear resistance ensure uniform and unbiased bottom contact when the light guide assembly is placed. When the light guide assembly is inserted into the perforated hole, the glass plate prevents scratches or deformation caused by direct metal contact. Its transparency allows for easy observation of the assembly's placement. Notches at the four corners of the concave area reduce overall weight and provide clearance for operation, preventing interference during handling or installation. This structure eliminates defects such as component misalignment and scratches caused by unevenness or friction in the fixture, significantly improving the inspection yield.

[0010] In detail, a positioning shaft is fixedly installed on the side of the steel tool away from the concave side. The positioning shafts are symmetrically distributed at both ends along one side of the steel tool, and bearings are interference-fitted onto the surface of the positioning shafts.

[0011] In detail, two positioning seats are fixed on the outer ring wall of the bearing, and the two positioning seats are arranged at 90 degrees.

[0012] In detail, the surface of the steel tool is fixedly mounted with a positioning sleeve by a bracket, and a positioning pin is slidably connected inside the positioning sleeve. One end of the positioning pin is inserted and docked with the inside of any positioning seat.

[0013] In detail, a spring is wound around the surface of the positioning pin, and the two ends of the spring are fixedly installed to the end of the positioning pin and the end face of the positioning sleeve, respectively.

[0014] In detail, an extension plate is fixedly installed on the outer ring wall of the positioning sleeve, and a threaded sleeve is installed through the end of the extension plate away from the bearing.

[0015] In detail, the internal threads of the threaded sleeve are fitted with a threaded knob, and a pressing plate is fixedly installed at the end of the threaded knob near the steel tool.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. This solution replaces the traditional screw fixing. The groove inside the steel part is directly embedded with the glass block, and the steel part is made low around the glass block so that the glass block is in the shape of a protrusion. That is, the direct contact surface of the light guide plate is the whole glass block, which prevents defects such as scratches, white spots and white marks from the light guide plate from the source, thereby improving the yield, reducing rework costs, reducing customer complaints and abnormalities, and increasing customer trust.

[0018] 2. As described in point 1, the design of the positioning shaft, bearings, and rotatable extension plate enables multi-angle positioning and rapid switching of the lamp guide assembly. The cooperation between the positioning pin and the spring allows the extension plate to be stably fixed in a right-angle or removed position, making operation simple and precise. The threaded linkage mechanism of the threaded knob and the clamping plate can quickly clamp the lamp guide assembly, ensuring no displacement during the inspection process and improving inspection efficiency.

[0025] 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.

[0026] Example 1

[0027] Reference Figures 1-5 A fixture for placing steel components for light guide detection includes a steel fixture 1. The interior of the steel fixture 1 is provided with a hollow hole 11. Both the steel fixture 1 and the hollow hole 11 are rectangular structures. A recess 12 is provided on the front side of the steel fixture 1. A notch 14 is provided on the edge of the recess 12, penetrating the edge of the steel fixture 1. The notch 14 is distributed along the four apex positions of the recess 12.

[0028] A glass plate 13, which is made of tempered glass, is inserted inside the recess 12.

[0029] The steel fixture 1 is hollowed out and has low edges and inner grooves to form an inner recess 12, which is then fitted with a glass plate 13 to prevent defects from continuing to occur from the source and improve the yield rate.

[0030] A mounting plate 15 is welded and fixed to one side of the steel fixture 1. The mounting plates 15 are symmetrically distributed along both sides of the steel fixture 1. Several mounting holes 16 are opened on the surface of the mounting plates 15, and the several mounting holes 16 are arranged in the same row.

[0031] It should be further noted that a positioning shaft 2 is fixedly installed on the side of the steel tool 1 away from the concave 12. The positioning shaft 2 is symmetrically distributed at both ends along one side of the steel tool 1. The surface of the positioning shaft 2 is interference-fitted with a bearing 21, which can rotate stably based on the positioning shaft 2.

[0032] It should be further explained that two positioning seats 22 are fixedly distributed on the outer ring wall of the bearing 21. The two positioning seats 22 are arranged at 90 degrees. When the positioning pin 24 is docked with the current positioning seat 22, the extension plate 3 can approach the hollow hole 11. When the positioning pin 24 is inserted with the other positioning seat 22, the extension plate 3 can be rotated 90 degrees and removed.

[0033] It should be further explained that a positioning sleeve 23 is fixedly installed on the surface of the steel tool 1 by a bracket. A positioning pin 24 is slidably sleeved inside the positioning sleeve 23. One end of the positioning pin 24 is inserted and connected to the inside of any positioning seat 22. The positioning pin 24 has a hand-pulled structure, which is easy to operate. The positioning pin 24 cooperates with the positioning seat 22 to fix the position of the extension plate 3.

[0034] It should be further noted that a spring 25 is wound around the surface of the positioning pin 24. The two ends of the spring 25 are fixedly installed to the end of the positioning pin 24 and the end face of the positioning sleeve 23, respectively. The spring 25 can ensure the stable extension and repositioning of the positioning pin 24.

[0035] It should be further explained that an extension plate 3 is fixedly installed on the outer ring wall of the positioning sleeve 23. A threaded sleeve 31 is installed through the end of the extension plate 3 away from the bearing 21. The extension plate 3 can be removed from the position of the hollow hole 11 when the light guide assembly is inserted, so that the light guide assembly can be properly inserted into the interior of the hollow hole 11. When it is necessary to position the light guide assembly, the extension plate 3 can be returned to the position of the hollow hole 11.

[0036] It should be further explained that a threaded knob 32 is installed inside the threaded sleeve 31. A pressing plate 33 is fixedly installed at one end of the threaded knob 32 near the steel tool 1. When the lamp guide assembly is placed inside the hollow hole 11, the threaded knob 32 is rotated to make it threadedly installed with the threaded sleeve 31, so that the pressing plate 33 fits and abuts against the back of the lamp guide assembly, thereby ensuring the stable installation of the lamp guide assembly.

[0037] In practice

[0038] The steel fixture 1 in this solution forms a precise positioning space for the light guide component through the design of the internal hollow hole 11 and the front recess 12. The recess 12 is recessed around the edges and milled into grooves before tempered glass plate 13 is inserted. The flatness and wear resistance of the glass ensure that the bottom contact surface of the light guide component is uniform and without deviation when it is placed. When the light guide component is placed into the hollow hole 11, the glass plate 13 can avoid scratches or deformation caused by direct metal contact. At the same time, its transparency makes it easy to observe the placement status of the component. The notches 14 are distributed at the four corners of the recess 12, which not only reduces the overall weight, but also provides clearance for operation and avoids interference during handling or installation. Through this structure, the defects such as component displacement and scratches caused by unevenness or friction of the fixture are eliminated from the source, and the inspection yield is significantly improved.

[0039] The extension plate 3 achieves stable rotation through the interference fit between the bearing 21 and the positioning shaft 2. Its core function is controlled by the positioning seat 22 and the positioning pin 24. When the lamp guide assembly needs to be placed into the cutout hole 11, the operator pulls out the positioning pin 24 and rotates the extension plate 3 to a 90-degree position (out of the cutout hole 11 area). At this time, the assembly can be placed without obstruction. After placement, the extension plate 3 rotates back to the initial position, and the positioning pin 24 is inserted into another set of positioning seats 22 under the elastic force of the spring 25 to achieve fixation. The threaded knob 32 then screws into the threaded sleeve 31, pushing the pressing plate 33 to press against the back of the lamp guide assembly, forming a three-point clamping (the glass plate 13 supports the bottom, and the pressing plate 33 presses against the side). This dynamic adjustment design ensures both operational flexibility and absolute stability of the assembly during the testing process, avoiding misjudgments caused by displacement.

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.
