Description

Technical Field

[0001] This utility model relates to the field of backlight processing technology, and in particular to a positioning fixture for backlight processing. Background Technology

[0002] With the continuous development of display technology, backlights are widely used in LCD displays, lighting, and other fields. In the backlight manufacturing process, precise positioning is crucial for ensuring product quality and production efficiency. Positioning fixtures, as core auxiliary equipment, enable the rapid and accurate installation and fixation of backlight components, providing stable support for subsequent assembly, welding, and testing processes.

[0003] Existing positioning fixtures are difficult to use for positioning backlights of different sizes, which limits their practical application.

[0004] To address this, a positioning fixture for backlight processing is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a positioning fixture for backlight processing to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A positioning fixture for backlight processing includes a main body mechanism and a working mechanism disposed on one side of the top of the main body mechanism. The main body mechanism includes: a working plate, a multi-level limiting groove disposed inside the working plate, a hollow plate disposed at the bottom of the working plate, a hollow groove disposed inside the hollow plate, a first vacuum pump disposed on one side of the bottom of the hollow plate, and a first limiting component, a second limiting component, a third limiting component and a fourth limiting component disposed inside the multi-level limiting groove. The first limiting component includes a limiting plate disposed at the bottom of the multi-level limiting groove, a silicone ring disposed on the outer wall of the limiting plate, and an opening disposed inside the limiting plate.

[0007] In some embodiments, a retaining ring is provided on the top outer wall of the working plate, and a working groove is provided inside the retaining ring.

[0008] In some embodiments, the working mechanism includes a support plate disposed on one side of the working plate and a reinforcing plate disposed on one side of the support plate.

[0009] In some embodiments, a top plate is provided on the top of the support plate, and a hydraulic cylinder is provided at the bottom of the top plate.

[0010] In some embodiments, an adsorption plate is provided at the bottom of the hydraulic cylinder, a second vacuum pump is provided on one side of the top of the adsorption plate, and a porous silicone pad is provided at the bottom of the adsorption plate.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] A positioning fixture for backlight processing utilizes a multi-level limiting groove in the main body, along with flexibly adjustable first, second, third, and fourth limiting components, to achieve precise adaptation to backlights of different sizes. The combination of the limiting plate and silicone ring not only securely supports the backlight but also prevents surface damage. Openings, combined with a hollow plate and a first vacuum pump, create negative pressure adsorption, enhancing the fixing effect. The multi-level structure and adsorption function work synergistically to not only achieve top-mounting and positioning of backlights of various sizes but also improve processing stability and yield, significantly increasing production efficiency and processing quality.

[0013] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] Example 1:

[0024] like Figure 1-3 As shown, a positioning fixture for backlight processing includes a main body 100 and a working mechanism 200 mounted on the top side of the main body 100. The main body 100 includes: a working plate 101, a multi-level limiting groove 102 formed inside the working plate 101, a hollow plate 103 mounted on the bottom of the working plate 101, a hollow groove 104 formed inside the hollow plate 103, a first vacuum pump 105 mounted on the bottom side of the hollow plate 103, and a first limiting component 106, a second limiting component 107, a third limiting component 108, and a fourth limiting component 105 placed inside the multi-level limiting groove 102. The limiting component 109 and the first limiting component 106 include a limiting plate 106a placed at the bottom of the multi-level limiting groove 102 and a silicone ring 106b bonded to the outer wall of the limiting plate 106a. The multi-level limiting groove 102 of the main body 100, together with the first, second, third and fourth limiting components that can be flexibly adjusted, can achieve precise adaptation to backlights of different sizes. The combination of the limiting plate 106a and the silicone ring 106b can not only stably lift the backlight, but also the opening 106c opened inside the limiting plate 106a. The opening 106c, together with the hollow plate 103 and the first vacuum pump 105, forms a negative pressure adsorption to enhance the fixing effect.

[0025] In this embodiment, a retaining ring 110 is installed on the top outer wall of the working plate 101, and a working groove 111 is formed inside the retaining ring 110.

[0026] In this embodiment, the working mechanism 200 includes a support plate 201 installed on one side of the working plate 101 and a reinforcing plate 202 installed on one side of the support plate 201. A top plate 203 is installed on the top of the support plate 201, and a hydraulic cylinder 204 is installed at the bottom of the top plate 203. An adsorption plate 205 is installed at the bottom of the hydraulic cylinder 204. A second vacuum pump 206 is installed on one side of the top of the adsorption plate 205. A porous silicone pad 207 is adhered to the bottom of the adsorption plate 205. The first hydraulic cylinder 204 drives the adsorption plate 205 to move downward, and the second vacuum pump 206 extracts the air at the bottom of the adsorption plate 205 so that the workpiece is adsorbed on the bottom porous silicone pad 207, which is convenient for picking up and placing.

[0027] In this embodiment: the multi-level limiting groove 102 of the main body mechanism 100, together with the first, second, third and fourth limiting components that can be flexibly adjusted, achieves precise adaptation to backlights of different sizes. The combination of the limiting plate 106a and the silicone ring 106b can not only stably lift the backlight, but also avoid surface damage. The opening 106c, together with the hollow plate 103 and the first vacuum pump 105, forms a negative pressure adsorption, which enhances the fixing effect. The multi-level structure and adsorption function work together to not only realize the top mounting and positioning of backlights of multiple sizes, but also improve the processing stability and yield rate, and significantly improve production efficiency and processing quality.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
