Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a glass supporting device and a glass chamfering and edge grinding device. Background Art

[0002] Panel glass is widely used in the manufacturing process of electronic devices such as LCDs, TVs, and touch screens. Especially in the production of display panels, the quality of the glass surface directly affects the display effect and service life of the product. As electronic products have increasingly higher requirements for the cleanliness of display panel glass, they are more sensitive to glass surface defects and dust pollution.

[0003] Panel glass is usually cut into small pieces by cutting large pieces of glass according to the required product size. However, there will be a difference between the size of the glass after cutting and the required size, so the edge of the glass needs to be chamfered and edged. In the past, workers usually used grinding wheel equipment to manually chamfer and edge grind the glass. With the development of technology, the glass is now placed flat on the support table. After the glass is positioned and fixed, the grinding wheel equipment is driven by a two-axis mechanism to move along the edge of the glass to complete the chamfering and edge grinding.

[0004] However, there are two problems with the current glass chamfering and edging devices: first, when chamfering and edging the glass, the edge of the glass needs to extend beyond the edge of the supporting table and be exposed for processing, but the length and width of panel glass vary greatly depending on different needs, so different sizes of supporting tables need to be designed for different sizes of glass, which not only has high production costs but also makes production line maintenance difficult. Second, since there will be an error between the size of the glass after cutting and the required size, and the error conditions of different batches of glass also vary, it is difficult to control the feed amount during grinding, and multiple small feeds are required, which makes work efficiency extremely slow and easily causes glass breakage.

DETAILED DESCRIPTION

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, combined Figure 2 and Figure 3 A glass supporting device of the present invention includes a first supporting part 2 and a second supporting part 3.

[0032] The horizontal upper surface of the first supporting portion 2 is a first contact surface 201. The first supporting portion 2 is located in the center of the entire glass supporting device, and supports small-sized glass.

[0033] The second supporting part 3 is arranged in a ring shape around the first supporting part 2 and its horizontal upper surface is the second contact surface 301, which supports large-sized glass; the second supporting part 3 is installed on a stable base, and the second supporting part 3 is installed on the base through a guide rail slider mechanism, so that the second supporting part 3 moves in the vertical direction of the horizontal plane, and the second contact surface 301 is flush with the first contact surface 201 or drops to a position lower than the first contact surface 201; a plurality of adsorption holes are opened on the first contact surface 201 and the second contact surface 301, and the glass 1 is fixed by vacuum adsorption through the adsorption holes to prevent the glass 1 from being During the processing of the grinding mechanism, it receives a pushing force from the side direction and moves; when there is a height difference between the second contact surface 301 and the first contact surface 201, the small-sized glass 1 is attached to the first contact surface 201 and its outer edge exceeds the outer contour of the first contact surface 201, and the second supporting part 3 descends to avoid the grinding mechanism so that the grinding mechanism can contact the edge of the glass 1 without hindrance; or when the second contact surface 301 is flush with the first contact surface 201, the large-sized glass 1 is attached to the first contact surface 201 and the second contact surface 301 at the same time and its outer edge exceeds the outer contour of the second contact surface 301.

[0034] exist Figure 2In a preferred embodiment shown, since the panel glass 1 has extremely high requirements for surface cleanliness, it is necessary to reduce the contact area between the contact surface and the lower surface of the glass 1 as much as possible. The upper surfaces of the first supporting part 2 and the second supporting part 3 are both provided with a raised step 21. The step 21 is arranged in a ring shape along the outer contour edge of the first contact surface 201 or the second contact surface 301. Adsorption holes are arranged on the upper surface of the step 21. The adsorption holes on the step 21 can be arranged more densely, so the contact area between the step 21 and the glass 1 is smaller. At the same time, the stability of the glass 1 adsorbed and fixed is ensured by the denser adsorption holes. Moreover, the step 21 is arranged at the edge of the contact surface, so that the adsorption position surrounds the edge of the glass 1, thereby ensuring the adsorption strength. .

[0035] exist Figure 2 In a preferred embodiment shown in the figure, a ball groove is arranged on the first contact surface 201 or the second contact surface 301, and a ball 22 is arranged in the ball groove. The ball 22 can be a plastic universal ball, which can reduce the friction damage that may be caused when the ball 22 contacts the lower surface of the glass 1; the ball 22 contacts the lower surface of the glass 1 adsorbed on the first contact surface 201 or the second contact surface 301, and the glass 1 is supported by the ball 22. The point contact formed by a plurality of balls 22 further reduces the contact area with the glass 1.

[0036] exist Figure 2 In a preferred embodiment shown, the second supporting portion 3 includes a supporting unit 31 .

[0037] Among them, a plurality of supporting units 31 are arranged in a ring shape around the first supporting part 2, each supporting unit 31 is arranged at intervals from the outer edge of the first contact surface 201, and the upper surfaces of the plurality of supporting units 31 constitute the second contact surface 301. In the above design, the second supporting part 3 forms a segmented structure, and each supporting unit 31 can be independently raised and lowered, so that one side of the second supporting part 3 can be independently raised and lowered, thereby making the supporting device suitable for supporting glass of more sizes.

[0038] exist Figure 2 In a preferred embodiment shown, the glass 1 is transferred to the supporting device by a mechanical fork, the fork tines of the mechanical fork hold the bottom of the glass 1, and the mechanical fork descends to place the glass 1 on the supporting device, but this requires avoiding the fork tines holding the lower surface of the glass 1, so a clearance groove 202 is provided on the first contact surface 201, and the two ends of the clearance groove 202 extend along the length direction or width direction of the glass 1; adjacent supporting units 31 are arranged at intervals to form the clearance groove 202. When the mechanical fork descends, the fork tines descend into the clearance groove 202, so that the glass 1 can be placed on the contact surface; in addition, the clearance groove 202 also plays a role in locating the placement position of the glass 1.

[0039] like Figure 4 As shown, combined Figure 5 A glass chamfering and edge grinding device of the present invention includes a glass supporting device, a platform 4, a movable base 5, a grinding assembly 6 and a visual observation part 7.

[0040] Among them, the glass supporting device can adopt any of the above embodiments. When the glass supporting device supports glasses 1 of different sizes, the edge of the glass 1 will exceed the edge of the contact surface, not only the size of the glass 1 of different batches will have errors with the standard size, but also when the mechanical fork places the glass 1 on the supporting device, the width of the edge of different glasses 1 will also have errors, and the error part that needs to be ground for large-sized glass 1 and small-sized glass 1 is also different. This makes it difficult for the grinding assembly 6 to determine the grinding feed amount for different glasses 1.

[0041] The platform 4 is provided with a first station 401 and a second station 402. The first station 401 is a grinding station, and the second station 402 is an identification and detection station.

[0042] The movable base 5 is disposed on the platform 4 and a glass supporting device is disposed thereon. The movable base 5 drives the glass supporting device to synchronously reciprocate horizontally between the first station 401 and the second station 402 .

[0043] The grinding assembly 6 is disposed above the platform 4 and is used to chamfer and grind the edge of the glass 1 .

[0044] The visual observation unit 7 is arranged above the platform 4 and is used to identify the edge contour of the glass 1; when the movable base 5 moves to the second station 402, the visual observation unit 7 identifies the edge contour of the glass 1; when the movable base 5 moves to the first station 401, the grinding assembly 6 moves horizontally back and forth in the vertical direction of the moving direction of the movable base 5 and performs chamfering and edge grinding on the edge of the glass 1. Before the grinding process, the software needs to import the product CAD standard size drawing, and then compare the edge contour of the glass 1 identified by the visual observation unit 7 with the standard size, so as to determine the error amount between the identified edge contour of the glass 1 and the edge contour of the standard size, and then determine the feed amount of the grinding assembly 6.

[0045] exist Figure 4In a preferred embodiment shown, positioning marks are provided on at least three corners of the first contact surface 201, and the lines connecting the positioning marks intersect vertically; two visual observation parts 7 are symmetrically arranged on both sides of the moving direction of the movable base 5, and the visual observation parts 7 recognize the outer contour of the corners of the glass 1 and the positioning marks. Since the glass 1 is transparent, the visual observation parts 7 can also visually recognize the positioning marks when the glass 1 is placed on the contact surface. Since the position of the positioning mark is determined, the outer contour of the contact surface is also determined, and the three positioning marks on the three corners of the contact surface form a rectangular coordinate system, so the coordinate feature information of the outer contour of the contact surface can be determined; the two visual observation parts 7 are distributed on both sides of the glass 1, and as the glass 1 moves from the first station 401 to the second station 402 driven by the supporting device, the two visual observation parts 7 respectively identify the two corners of the glass 1, totaling four corners, and the center of the visual observation part 7 and the positioning mark is determined, so the coordinate feature information of each corner can be identified, and then the software can generate the actual product shape of the glass 1 according to the moving distance of the glass 1 and the coordinate information characteristics of the four corners, and then compare it with the standard size, and then determine the feed amount of the grinding component 6.

[0046] exist Figure 6 In a preferred embodiment shown, when grinding the glass 1 , the grinding assembly 6 includes an assembly body 61 , a grinding disc 62 , a waterproof cover 63 and a water spray nozzle 64 .

[0047] The component body 61 is arranged above the platform 4 and moves horizontally back and forth in a direction perpendicular to the moving direction of the movable base 5. A crossbeam is set on the platform 4, and a two-axis driving mechanism is installed on the crossbeam. The component body 61 is installed on the two-axis driving mechanism and is driven to move. The component body 61 includes a shell, and electrical components such as electrodes that drive the grinding disc 62 to rotate are arranged in the shell. Since this application does not involve improvements to the principle of the grinding equipment and the driving mechanism, the internal structure of the component body 61 is not described in detail.

[0048] The grinding disc 62 is disposed on the end of the component body 61 facing the platform 4 and is used to chamfer and grind the edge of the glass 1 .

[0049] Since water needs to be sprayed during the grinding process, glass dust and water mist will be generated. If they splash onto the upper surface of the glass 1, scratches are likely to be caused. Therefore, the waterproof cover 63 is arranged on the component body 61 and covers the grinding disc 62. The waterproof cover 63 is provided with a plurality of window grooves 601, and both ends of the window grooves 601 extend horizontally in an arc shape. The window grooves 601 expose the edge of the grinding disc 62 to the outside world. The edge of the glass 1 enters the window grooves 601 and contacts the edge of the grinding disc 62 for chamfering and edge grinding, so that the glass dust and water mist generated by grinding can be caught by the waterproof cover 63 and will not splash onto the glass 1.

[0050] A plurality of water spray nozzles 64 are disposed on the component body 61 and are evenly arranged around the grinding disc 62 ; the water spray nozzles 64 spray water toward the window groove 601 , thereby cooling the grinding portion of the glass 1 and the grinding disc 62 .

[0051] exist Figure 6 In a preferred embodiment shown, eight window slots 601 are provided, with the center of the grinding disc 62 as the center of the circle and the two ends of the moving direction of the movable base 5 as 0° and 180°, and the eight window slots 601 are respectively provided at the positions of 0°, 45°, 90°, 135°, 180°, 225°, 270° and 315°. Specifically, the edges of the grinding disc 62 exposed at the positions of the window slots 601 at 0°, 90°, 180° and 270° grind the four edges of the glass 1 respectively, and the edges of the grinding disc 62 exposed at the positions of the window slots 601 at 45°, 135°, 225° and 315° chamfer the four corners of the glass 1 respectively. Therefore, there are also eight corresponding water spray nozzles 64. When it is necessary to grind an edge or a corner of the glass 1, the corresponding water spray nozzle 64 automatically sprays water into the corresponding window slot 601.

[0052] exist Figure 7 In a preferred embodiment shown, in order to further reduce the adverse effects of glass dust and water mist generated by grinding on the glass 1 , the grinding assembly 6 further includes an annular air knife 65 and an air intake 66 .

[0053] The annular wind knife 65 is arranged on the component body 61 and sleeved on the outside of the waterproof cover 63. The annular wind knife 65 sprays air toward the platform 4 and surrounds the waterproof cover 63 to form an air curtain to prevent the remaining water mist from splashing out.

[0054] A plurality of air inlets 66 are provided on the end surface of the component body 61 facing the platform 4 and are arranged around the waterproof cover 63. The air inlets 66 suck out the atomized water vapor in the air curtain, thereby protecting the appearance quality of the glass 1 product to the greatest extent.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
