[0002] Under the trend of increasingly thin and light electronic products, the importance of glass substrate thinning process is increasingly prominent. The thickness of liquid crystal display, as the core component of electronic devices, directly affects the overall thickness of the product. For example, the thin and light of products such as mobile phones, notebook computers, tablet computers, etc. needs to be realized by reducing the thickness of glass substrate. The thinning of glass substrate is usually completed by etching process, but due to the brittleness of glass substrate itself, how to ensure its uniform thickness and smooth surface during the thinning process becomes a key problem. Therefore, in order to improve the performance and user experience of electronic products, the accuracy of thinning process and the uniformity of glass substrate become particularly important.
[0003] In order to explore the thinning ability of different components of etching liquid to glass substrate, thinning experiment needs to be carried out. In the thinning experiment of glass substrate, in order to ensure the experimental effect, it is usually necessary to fix the glass substrate by using a placing rack, and then put the placing rack into the etching liquid. The existing placing rack (for example: authorized announcement No. CN205525809U, name: a glass placing rack) includes an outer frame for supporting the glass to be placed; a plurality of limiting rods for limiting the glass to be placed; the plurality of limiting rods are divided into two groups and oppositely arranged, the distance between the two groups of limiting rods is adapted to the length or width of the glass to be placed; each limiting rod in each group is distributed in parallel along the height direction of the outer frame from top to bottom, and the two ends of each limiting rod are connected to the opposite inner side walls of the outer frame; the outer surface of each limiting rod is distributed with limiting grooves arranged in parallel along the axial direction; the groove width of the limiting groove is adapted to the thickness of the glass to be placed, and the glass is placed into the etching liquid for thinning after the glass is placed. Although this placing rack can fix the glass, it cannot adapt to glass substrates of different lengths because the position of the limiting rod is fixed. CONTENT OF THE UTILITY MODEL

The plurality of fixing components 20 and the plurality of first adjusting openings 111 and the plurality of second adjusting openings 121 are arranged in one-to-one correspondence, each fixing component 20 comprises two fixing clamping strips 21, and the two ends of the two fixing clamping strips 21 are movably arranged in the corresponding first adjusting opening 111 and second adjusting opening 121 respectively.
[0029] The technical scheme of the embodiment is applied to the glass substrate thinning experiment placing rack, which comprises: a placing rack body 10 and a plurality of fixing components 20. The placing rack body 10 comprises a first mounting plate 11 and a second mounting plate 12, the first mounting plate 11 and the second mounting plate 12 are oppositely arranged, the first mounting plate 11 and the second mounting plate 12 play a supporting role, and the carrying of the glass substrate thinning experiment placing rack is realized by clamping the first mounting plate 11 and the second mounting plate 12. The first mounting plate 11 has a plurality of first adjusting openings 111, the second mounting plate 12 has a plurality of second adjusting openings 121, and the plurality of first adjusting openings 111 and the plurality of second adjusting openings 121 are arranged in one-to-one correspondence. The plurality of fixing components 20 and the plurality of first adjusting openings 111 and the plurality of second adjusting openings 121 are arranged in one-to-one correspondence, each fixing component 20 comprises two fixing clamping strips 21, and the two ends of the two fixing clamping strips 21 are movably arranged in the corresponding first adjusting opening 111 and second adjusting opening 121 respectively, the to-be-thinned glass 100 is placed on the fixing clamping strip 21 for fixation, the distance between the two fixing clamping strips 21 can be adjusted by moving the fixing clamping strip 21, and then the to-be-thinned glass 100 of different widths can be adapted. The technical scheme of the embodiment effectively solves the poor adaptability of different lengths of glass substrates (i.e. to-be-thinned glass 100) in the prior art when the glass substrates are fixed.
[0030] As shown in some embodiments, Figure 1 the first mounting plate 11 and the second mounting plate 12 are both rectangular plates, the to-be-thinned glass 100 is parallel to the first mounting plate after being placed, the plurality of first adjusting openings 111 are arranged in parallel along the length direction of the first mounting plate 11, and the plurality of second adjusting openings 121 are arranged in parallel along the length direction of the second mounting plate 12. This arrangement enables the two opposite fixing clamping strips 21 to be adapted to the long side of the to-be-thinned glass 100 when the fixing clamping strip 21 is moved.
[0031] As shown in some embodiments, Figure 2As shown in the drawings, in some embodiments, the fixed clamping strip 21 comprises a fixed rod 211 and a plurality of limiting blocks 212, the fixed rod 211 has a mounting section 2111 in a cuboid structure, and the plurality of limiting blocks 212 are sequentially arranged along the length direction of the mounting section 2111, and the limiting blocks 212 abut against the glass substrate 100 to be thinned to fix the glass substrate 100 to be thinned.
[0032] As shown in the drawings, Figure 3 In some embodiments, the fixed rod 211 further has two groups of threaded sections 2112 connected to the two sides of the mounting section 2111 respectively, the two groups of threaded sections 2112 are respectively arranged in the first adjusting opening 111 and the second adjusting opening 121 arranged oppositely, and the two groups of first nuts are respectively screwed with the two groups of threaded sections 2112 and abut against the first mounting plate 11 and the second mounting plate 12 respectively.

For glass substrates 100 with a small thickness, they can be directly placed into the limiting notch 2123 for fixation. For glass substrates with a large thickness, the limiting blocks 212 can be moved so that two adjacent sets of limiting blocks 212 abut against two sides of the glass substrate 100 to be thinned, thereby achieving fixation.
[0037] like Figure 5 As shown, in some embodiments, a circular hole is provided on the inner wall of the limiting notch 2123. The purpose of the circular hole is to increase the contact area between the glass 100 to be thinned and the etching liquid. It should be noted that the limiting block 212 is made of Teflon.

The fixing strip 21 is rotatably disposed in the corresponding first adjustment opening 111 and second adjustment opening 121, and the orientation of the limiting notch 2123 can be changed by rotating the fixing strip 21.
