Description

Technical Field

[0001] This invention relates to the field of positioning device technology, and specifically to a rapid positioning device for grinding a TFT-LCD glass substrate surface grinding tray. Background Technology

[0002] During the grinding process of TFT-LCD glass substrates, the grinding tray holding the glass substrate needs to be re-grinded to ensure process requirements are met. When re-grinding the tray, it must be hoisted onto the marble tabletop of a specialized grinding equipment. This process requires precise placement of the tray on the worktable to ensure it is accurately positioned on the equipment's marble surface.

[0003] Currently, the method relies on manual observation of the relative position of the pallet and the marble countertop during the hoisting process. The pallet is positioned on the marble countertop through continuous attempts and adjustments. This manual positioning method is time-consuming and labor-intensive. Most importantly, the pallet is prone to tilting when it is placed on the marble positioning platform, which causes errors in subsequent positioning and results in poor positioning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid positioning device for grinding a TFT-LCD glass substrate surface grinding tray, solving the following technical problems:

[0005] How to place the pallet more neatly on the positioning platform.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A rapid positioning device for grinding a TFT-LCD glass substrate surface grinding tray includes a rectangular frame. Two sets of positioning parts are symmetrically and slidably arranged on the upper ends of each of the four sides of the rectangular frame. Each positioning part contains a positioning stage. The positioning part includes...

[0008] A slide block is slidably disposed on the upper end of a rectangular frame, and a first screw hole is provided on the upper surface of the slide block;

[0009] A skateboard, which is slidably mounted on the upper surface of a slide block;

[0010] A channel is provided on the surface of the slide plate that contacts the slide block;

[0011] The first bolt, the shank of the first bolt passing through the channel and the screw hole on the upper surface of the slide;

[0012] A connecting plate, the connecting plate being connected to the outer end of the sliding plate;

[0013] A spring, the spring being connected between the connecting plate and the slide;

[0014] A positioning plate is connected to the inner end of the slide plate, and the upper end of the positioning plate is inclined outward.

[0015] In a further embodiment, the slide block has an n-shaped cross-section.

[0016] In a further embodiment: the slide includes two parallel vertical plates and a horizontal plate connected between the upper ends of the two vertical plates. A second screw hole is provided on the vertical plate located on the outer side of the slide, and a second bolt passes through the second screw hole.

[0017] In a further embodiment, the cross-section of the skateboard is L-shaped.

[0018] In a further embodiment: the skateboard includes a horizontal board and a vertical board connected to one edge of the horizontal board, the vertical board being provided with anti-slip texture.

[0019] In a further embodiment: a gasket is provided on the inner side of the positioning plate, and the gasket is made of silicone.

[0020] In a further embodiment: the positioning plate is a rectangular steel plate with its upper end bent outwards.

[0021] Beneficial effects of the embodiments of the present invention:

[0022] When using this invention, since the pallet needs to pass through the inclined edges of the upper part of multiple positioning plates when it enters the positioning table surface, the lower position of the pallet can be initially regulated, which can effectively avoid the problem of the pallet being tilted and thus causing positioning difficulties. Moreover, after the pallet is placed on the positioning table through the positioning plates, there is no need to adjust its position; only the first bolt needs to be tightened, which is convenient and quick.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-3 As shown, this invention is a rapid positioning device for grinding a TFT-LCD glass substrate surface grinding tray, comprising a rectangular frame 100, which is made of aluminum profile. The upper surface of the rectangular frame 100 is smooth and can be used as a slide rail. A positioning platform 300 is provided inside the rectangular frame 100, which is made of marble. Two sets of symmetrical positioning parts 200 are slidably arranged on the upper ends of the four side rails of the rectangular frame 100. Each positioning part 200 is located on the side rail near the adjacent side, so that two sets of corresponding positioning parts 200 are distributed at the four corners of the rectangular frame 100. The positioning parts 200 are channel steel structural components.

[0032] The positioning part 200 includes a slide 201, which is slidably disposed on the upper end of the rectangular frame 100, and a first screw hole is provided on the upper surface of the slide 201; a sliding plate 202 is also slidably disposed on the upper surface of the slide 201, and a channel 203 is provided on the side surface of the sliding plate 202 that contacts the slide 201. The channel 203 is an elongated hole, and a first bolt 204 corresponding to the first screw hole on the upper surface of the slide 201 passes through the channel 203. The shank of the first bolt 204 passes through the channel 203 and the first screw hole, and the head is located above the channel 203, and the diameter of the head is greater than the width of the channel 203, so the head will not be submerged in the channel 203. The number of the first bolts 204 is at least one. For example, in this embodiment of the invention, the number of the first bolts 204 is two.

[0033] A downwardly extending connecting plate 206 is vertically connected to the outer upper side of the slide 201. A spring 207 is connected between the connecting plate 206 and the side wall of the slide 201. The elastic coefficient of the spring 207 is not specifically limited and can be determined according to actual application requirements, but it should be proportional to the mass of the tray 400. An upwardly extending positioning plate 208 is vertically connected to the inner upper side of the slide 201. The upper end of the positioning plate 208 is inclined outward relative to the lower end, that is, the positioning plate 208 is a rectangular steel plate with the upper end bent outward. Therefore, the elastic coefficient of the spring 207 should be large enough to ensure that the positioning plate 208 can be subjected to a sufficiently large elastic thrust, thereby meeting the requirements.

[0034] Please see Figure 4-5 Specifically, when using this positioning device, its initial state is that the first bolt 204 is loosened and the spring 207 is in a natural, non-stretched state. The operator lowers the tray 400 from top to bottom, aligning it with the positioning platform 300, and moves the side of the tray 400 downwards along the inclined edge of the upper end of the positioning plate 208 until it contacts the vertical surface of the lower end of the positioning plate 208 and stops on the surface of the positioning platform 300. At this point, the tray 400 will cause the positioning plate 208 to move outwards. The positioning plate 208 will cause the slide plate 202 to slide outwards on the slide block 201. The slide block 201 will then cause the connecting plate 206 to move outwards accordingly. The connecting plate 206 will cause the spring 207 to undergo tensile elastic deformation. At this point, the positioning plate 208 will firmly press the side of the tray 400 against the platform. Then, tightening the first bolt 204 will fix the position of the slide plate 202, and then fix the position of the positioning plate 208, so that the multiple positioning plates 208 can position the pallet 400. Since the pallet 400 needs to pass through the inclined edge of the upper end of the multiple positioning plates 208 when it enters the surface of the positioning table 300, the lower position of the pallet 400 can be initially regulated, which can effectively avoid the problem of the pallet 400 being placed tilted and thus causing positioning difficulties. Moreover, after the pallet 400 is placed on the positioning table 300 through the positioning plate 208, there is no need to adjust its position. Just tighten the first bolt 204, which is convenient and quick.

[0035] Furthermore, the slide block 201 has an n-shaped cross section. The slide block 201 includes two parallel vertical plates and a horizontal plate connected between the upper ends of the two vertical plates. A second screw hole is provided on the vertical plate located on the outer side of the slide block 201, and a second bolt 205 passes through the second screw hole.

[0036] In detail, when the second bolt 205 is loosened, the slide 201 can slide on the upper end of the rectangular frame 100, thereby adjusting the position of the slide 201, and thus the overall position of the positioning part 200. When the second bolt 205 is tightened, the position of the slide 201 is fixed on the rectangular frame 100. By adjusting the position of the positioning part 200, the distribution of multiple positioning parts 200 can be changed, thereby changing the fixing point of the pallet 400. Operators can select the most suitable fixing point based on testing, thus achieving the best positioning effect.

[0037] Furthermore, the skateboard 202 has an L-shaped cross-section; the skateboard 202 includes a horizontal board and a vertical board connected to one edge of the horizontal board, and the vertical board is provided with anti-slip texture.

[0038] When adjusting the position of the skateboard 202, the staff can move the skateboard 202 as a whole by manually moving the vertical board, which is more convenient and faster. The anti-slip texture on the vertical board helps to increase the friction between the staff and the vertical board, preventing slippage.

[0039] Furthermore, a gasket 209 is provided on the inner side of the positioning plate 208. The gasket 209 is made of silicone. The gasket 209 helps to reduce the wear on the surface of the pallet 400 when the positioning plate 208 presses against the pallet 400, and avoids the positioning plate 208 from damaging the surface of the pallet 400.

[0040] Working principle of the invention:

[0041] When using this positioning device, its initial state is that the first bolt 204 is loosened and the spring 207 is in a natural, non-stretched state. The operator lowers the tray 400 from top to bottom, aligning it with the positioning platform 300, and moves the side of the tray 400 downwards along the inclined edge of the upper end of the positioning plate 208 until it contacts the lower vertical surface of the positioning plate 208 and rests on the surface of the positioning platform 300. At this point, the tray 400 will cause the positioning plate 208 to move outwards. The positioning plate 208 will cause the slide plate 202 to slide outwards on the slide block 201. The slide block 201 will then cause the connecting plate 206 to move outwards accordingly. The connecting plate 206 will cause the spring 207 to undergo tensile elastic deformation. At this point, the positioning plate 208 will firmly press the side of the tray 400 against the platform. Then, tightening the first bolt 204 will fix the position of the slide plate 202, and then fix the position of the positioning plate 208, so that the multiple positioning plates 208 can position the pallet 400. Since the pallet 400 needs to pass through the inclined edge of the upper end of the multiple positioning plates 208 when it enters the surface of the positioning table 300, the lower position of the pallet 400 can be initially regulated, which can effectively avoid the problem of the pallet 400 being placed tilted and thus causing positioning difficulties. Moreover, after the pallet 400 is placed on the positioning table 300 through the positioning plate 208, there is no need to adjust its position. Just tighten the first bolt 204, which is convenient and quick.
