Description

Technical Field

[0001] This utility model relates to the field of substrate clamping technology, and in particular to a reflector substrate clamping device. Background Technology

[0002] In the precision engraving process of the reflector substrate, the traditional precision engraving machine fixture uses a long strip of Teflon-coated connecting rod to connect the side plate. After a period of use, deformation and damage will occur. When the precision engraving fixture is deformed, the position of the precision engraving machine insert will change during use, and the glass substrate will tilt and collide, resulting in chipping defects. In order to address the above defects, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a reflector substrate clamp that solves the problems of short service life and easy deformation and damage of current substrate clamps.

[0004] To address the aforementioned problems, this utility model provides a reflector substrate clamp, comprising an upper frame, a lower frame, and upper and lower connecting rods. Both the upper and lower frames are provided with several substrate clamping areas and toothed portions. The toothed portions are used to fix the substrate in the substrate clamping areas. A transverse connecting rod is provided in the substrate clamping area of ​​the lower frame to support the bottom of the substrate. The upper and lower connecting rods connect the upper and lower frames. The upper frame includes a Teflon interlayer and resin layers located on both sides of the Teflon interlayer. The resin layers are preferably made of bakelite. A Teflon interlayer is added between the upper and lower resin layers, and the entire frame is connected using the upper and lower connecting rods. The intermediate Teflon layer is protected by the upper and lower resin layers, reducing wear on the Teflon during use and ensuring that the Teflon will not deform or break during long-term use.

[0005] According to one embodiment of the present invention, the lower frame is made of resin.

[0006] Optionally, the lower frame can be made of the same material as the upper frame to further improve its service life.

[0007] According to one embodiment of the present invention, the transverse connecting rod is covered with a flexible layer, preferably a rubber sleeve covering the transverse connecting rod.

[0008] According to one embodiment of the present invention, the toothed portion is disposed on the inner walls of both sides of the substrate clamping area.

[0009] According to one embodiment of the present invention, the upper frame is provided with a hollow area to reduce the weight and cost of the fixture.

[0010] According to one embodiment of the present invention, the lower frame is provided with a hollow area to reduce the weight and cost of the fixture.

[0011] According to one embodiment of the present invention, one side of the substrate clamping area of ​​the upper frame has a notch to facilitate the differentiation of the clamping direction.

[0012] According to one embodiment of the present invention, at least four sets of upper and lower connecting rods are provided around each substrate clamping area to ensure the strength of the frame.

[0013] According to one embodiment of the present invention, two sets of substrate clamping areas are provided on both the upper frame and the lower frame.

[0014] According to one embodiment of the present invention, the upper and lower connecting rods are connected to the upper frame and the lower frame by bolts.

[0015] The beneficial effects of this utility model are that by setting up an upper frame composed of a Teflon interlayer and resin layers on both sides of the Teflon interlayer, and then connecting the entire frame with upper and lower connecting rods, the middle Teflon layer of the upper frame is protected by the upper and lower resin plates, reducing wear on the Teflon during use. This ensures that the Teflon will not deform or break under long-term use, extends the service life of the clamp, prevents tilting during insertion, and improves product quality and efficiency.

[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0022] A mirror substrate clamp, such as Figure 1 It includes an upper frame 1, a lower frame 2, and upper and lower connecting rods 4.

[0023] Two substrate clamping areas 6 are provided in the upper frame 1 and the lower frame 2, such as Figure 2 The substrate 5 is installed in the substrate clamping area 6 for clamping. A hollow area 3 is provided between the two substrate clamping areas 6 to reduce the weight and cost of the fixture. One side of the substrate clamping area 6 of the upper frame 1 has a notch 16 to facilitate the differentiation of the fixture direction.

[0024] The two side walls of the substrate clamping area 6 are provided with tooth-like portions 7, such as... Figure 4 As shown, the substrate is positioned and clamped by the grooves between the toothed portions 7, and the substrate is fixed in the substrate clamping area 6 by the toothed portions 7. The root and end edges of the toothed portions 7 are all machined with rounded corners.

[0025] Each substrate clamping area 6 of the lower frame 2 is provided with at least one transverse connecting rod 22. While ensuring the strength of the clamp, the overall weight of the clamp is reduced. The transverse connecting rod 22 is used to support the bottom of the substrate. To avoid hard collision with the substrate, the transverse connecting rod 22 is covered with a flexible layer. It is preferable to use a rubber sleeve to cover the transverse connecting rod 22.

[0026] The upper and lower connecting rods 4 connect the upper frame 1 and the lower frame 2. Preferably, at least four sets of upper and lower connecting rods 4 are provided around each substrate clamping area 6, that is, a total of eight upper and lower connecting rods 4, to ensure the strength of the frame. In other embodiments, the number of upper and lower connecting rods 4 can be set according to the specific requirements.

[0027] The upper and lower connecting rods 4 are connected to the upper frame 1 and the lower frame 2 by bolts. Bolt holes 15 are provided at corresponding positions in the upper frame 1 and the lower frame 2 for installing bolts. The bolt holes 15 are preferably countersunk holes.

[0028] The upper frame 1 includes a Teflon interlayer 13 and resin layers 14 located on both sides of the Teflon interlayer 13. The resin layers 14 are preferably made of bakelite. The entire frame is assembled by adding a Teflon interlayer between the upper and lower resin layers and connecting the upper and lower connecting rods 4. The middle Teflon layer of the upper frame 1 is protected by the upper and lower resin layers, which reduces wear on the Teflon during use. This ensures that the Teflon will not deform or break under long-term use, thereby extending the service life of the fixture, preventing the engraving machine insert from tilting, and improving product quality and efficiency.

[0029] In this embodiment, the lower frame 2 is made of resin. In other embodiments, the lower frame 2 can be made of the same material as the upper frame 1 to further improve service life and avoid fixture deformation problems.

The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments.
