[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] Example 1

[0037] like Figure 1-11 As shown, a tempered glass positioning device includes a flexible pad 4, and a plurality of slots 41 formed in a linear array on the flexible pad 4 are respectively provided with conveying rollers;

[0038] The positioning mechanism 2 includes a plurality of driving wheels 1 arranged in an axial linear array on the conveying roller, a plurality of movable grooves 11 are formed in a circumferential array on the driving wheels 1, and a lining plate 21 is movably provided on the movable grooves 11. The driving wheels 1 are connected to the air source;

[0039] The lining plate 21 extends out of the driving wheel 1 as the gas is supplied, and the lining plate 21 is offset from the active groove 11 and exposed, and is adsorbed as the gas is exhausted.

[0040] Specifically, the flexible pad 4 is the cutting table for the glass plate 6. The multiple driving wheels 1 on the same conveyor roller will rotate together with the rotation of the conveyor roller. The flexible pad 4 is hollow, and the conveyor roller passes through the multiple slots 41 of the flexible pad 4. The driving wheel 1 is located in the multiple slots 41 on the flexible pad 4. The driving wheel 1 extends out of the flexible pad 4, thereby transporting the glass plate 6.

[0041] When the glass plate 6 is being transported, the conveying roller rotates to drive the driving wheel 1 to convey the glass plate 6 to the flexible pad 4. Then, the driving wheel 1 on some conveying rollers is connected to the exhaust gas source and started. At this time, the lining plate 21 and the movable groove 11 are offset and exposed, and the glass plate 6 is adsorbed and fixed. At this time, the other part of the conveying rollers are staggered with the adsorbed and fixed conveying rollers (with Figure 1 For reference, multiple inclined conveyor rollers penetrate the flexible pad 4 and are staggered, that is, the conveyor rollers adjacent to the conveyor rollers connected to the exhaust air source for adsorption and fixation are connected to the exhaust air source. The conveyor rollers are inflated, so that the backing plate 21 extends out of the driving wheel 1 with the air supply and is fixed to the glass plate 6. Finally, the flexible pad 4 rises to fit the glass plate 6 to complete the entire positioning and fixing steps, and the glass plate 6 is cut.

[0042] In the above scheme, the flexible pad 4 is an elastic sponge belt, which increases friction to assist fixation and provides buffering during cutting. A connecting plate can be set in the sponge belt and driven upward by hydraulic or pneumatic equipment to fit the glass plate 6 and buffer the vibration generated during cutting.

[0043] In the above technical solution, the glass plate 6 is transported by multiple conveying rollers. After the glass plate 6 is transported to the specified position, the conveying rollers corresponding to the glass plate 6 are alternately connected to the exhaust air source and the exhaust air source, so that part of the lining plate 21 and the movable groove 11 are misaligned and exposed, and the glass plate 6 is adsorbed and fixed by the exhaust air source to play a locking role, while the other part of the lining plate 21 extends the driving wheel 1 to play a supporting role, reducing the deformation of the flexible material, thereby reducing the offset and improving the positioning accuracy. While the glass plate 6 can be rolled and conveyed, it can also be fixed by adsorption and supported by inflation, reducing deformation while fixing. It is more suitable for the production mode of the automated assembly line when used with the flexible pad 4.

[0044] Furthermore, the air source for exhaust in the above solution may be a vacuum pump, and the air source for exhaust may be an air compressor.

[0045] As an embodiment provided by the present invention, a fixed plate 14 is provided on the driving wheel 1, and a folding plate 22 is provided between the fixed plate 14 and the lining plate 21. The three form a space, and an air source supplies air into the space to drive the lining plate 21 to extend.

[0046] Specifically, the folding plate 22 can stretch and contract to move. The lining plate 21, the folding plates 22 arranged on both sides of the lining plate 21, and the folding plate 22 used to support the fixed plate 14 form a space. When the outlet air source supplies air to the space, the air pressure in the space increases, pushing the folding plate 22 to stretch, thereby driving the lining plate 21 to be pushed out along the movable groove 11, thereby playing an auxiliary fixing effect.

[0047] Furthermore, the lining plate 21 is provided with an air release groove 214, which releases a portion of the gas when the air is inflated to limit the extension speed of the lining plate 21. The lining plate 21 is provided with a top plate 211, which always extends outside the driving wheel 1. When the outlet gas source delivers gas into the space (such as Figure 9 As shown in FIG2 , the liner plate 21 will eventually fit the inner wall of the driving wheel 1 to complete the inflation. At this time, the deflation channel of the deflation groove 214 is blocked and can no longer deflate. When the exhaust gas source sucks the space, (as shown in FIG2 , FIG2 ) Figure 10 As shown in the figure, because the exposed active groove 11 is blocked by the glass plate 6, the gas in the driving wheel 1 is drawn into the space along the exhaust groove 214 and is drawn away, so that the active groove 11 produces an adsorption effect.

[0048] Furthermore, the distance between the top plate 211 and the supporting plate 21 is 3 mm to 9 mm. The distance between the top plate 211 and the supporting plate 21 affects the distance between the top plate 211 and the supporting plate 21 in the adsorption state.

[0049] As an embodiment provided by the present invention, a driving ring 13 is provided on the driving wheel 1, a limiting protrusion 132 is provided on the driving ring 13, and limiting plates 210 are symmetrically provided on the lining plate 21, and the limiting protrusion 132 is attached to the limiting plate 210 on one side.

[0050] Specifically, the driving ring 13 is rotatably connected to the inner wall of the driving wheel 1 and is restricted and fixed (the restriction and fixation method can be fixed by fasteners; it can also be a snap fastener; or other fixing structures known to those skilled in the art). The restriction protrusion 132 is used to limit the movement direction of the restriction plate 210, thereby restricting the lining plate 21. Figure 8 As shown, when the driving ring 13 rotates counterclockwise, due to the friction on the surface of the glass plate 6, the top plate 211 will slide from right to left with the backing plate 21, but at this time the limiting protrusion 132 is fixed in contact with the limiting plate 210 and cannot move, thereby performing normal transportation of the glass plate 6. When it is necessary to expose the movable groove 11 to adsorb the glass plate 6, the driving ring 13 is rotated slightly in the opposite direction of the transportation direction. At this time, the top plate 211 is restricted by the glass plate 6, and only the driving wheel 1 rotates, causing the movable groove 11 and the top plate 211 to be misaligned, and a gap appears to adsorb the glass plate 6.

[0051] As an embodiment provided by the present invention, an elastic cover 20 is provided on the movable groove 11 , a top plate 211 is provided on the lining plate 21 , the top plate 211 is slidably connected to the elastic cover 20 , and a support bar 213 is provided on the top plate 211 .

[0052] Specifically, the elastic cover 20 is made of rubber and has good elasticity to assist the exposed movable groove 11 in adsorbing the glass plate 6. A accommodating cavity 212 is opened on the top plate 211, and a support bar 213 is provided in the accommodating cavity 212. The support bar 213 supports the top plate 211, thereby preventing the top plate 211 from deforming and causing the movable groove 11 to be accidentally exposed.

[0053] As an embodiment provided by the present invention, an air hole 133 is opened on the driving ring 13, an air ring 12 is rotatably connected in the driving wheel 1, an air pipe 121 connected to the air source is provided on the air ring 12, and a matching slip ring 131 is provided on the driving ring 13. The air ring 12 is rotatably connected to the matching slip ring 131 to extract or discharge air into the air hole 133. The conveying roller includes a connecting component 3 and a driving wheel 1. The connecting component 3 includes a connecting pipe 31 connecting two adjacent air pipes 121 and a connecting frame 32 connecting the two driving rings 13. The connecting frames 32 at the two ends are provided with end rings 321, and the end rings 321 are used to connect to the motor.

[0054] First, the conveying roller rotates to drive the driving wheel 1 to transport the glass plate 6 to the designated position on the flexible pad 4 where cutting is required. Then, the driving ring 13 is rotated slightly in the opposite direction of the transport direction. At this time, the top plate 211 is restricted by the glass plate 6, and only the driving wheel 1 rotates, causing the active groove 11 and the top plate 211 to be misaligned and exposed. Then, the driving wheel 1 on some conveying rollers is connected to the exhaust gas source and started, and is fixed by adsorption through the exposed active groove 11. At this time, the other part of the conveying rollers is inflated, so that the backing plate 21 extends out of the driving wheel 1 along with the air supply and is fixed to the glass plate 6. One adsorption and one production, fixing and reducing deformation.

[0055] Example 2

[0056] like Figure 1-11 As shown, a tempered glass production line includes a conveying roller, a backing plate 21 and a flexible pad 4 arranged on a driving wheel 1, and further includes:

[0057] a cutting assembly comprising a cutting unit for cutting a pre-cut groove 61 on the glass sheet 6;

[0058] The separation component includes conveying rollers arranged along a diagonal line, and two groups of conveying rollers on the same diagonal line are respectively inflated and exhausted.

[0059] Specifically, the cutting unit for cutting the glass plate 6 can be a glass cutting circular saw equipped with a servo motor frame, which cuts a pre-cut groove 61 on the glass plate 6. After cutting, the glass plate 6 is transported along the conveyor rollers to between the conveyor rollers arranged along the diagonal line. Then, the two groups of conveyor rollers on the same diagonal line are inflated and exhausted respectively to drive the glass plate 6 along the pre-cut groove 61 as the dividing line to be displaced up and down respectively, thereby completing the separation of the glass after cutting.

[0060] As an embodiment provided by the present invention, the separation assembly further includes a combination frame 5 for carrying the conveying rollers, and the combination frame 5 limits the conveying rollers to be arranged along the diagonal line.

[0061] As an embodiment provided by the present invention, a top plate 211 is provided on the backing plate 21, and the distance between the two is 8 mm to 16 mm. The distance between the backing plate 21 and the top plate 211 used for separation is greater than the distance used for locking and fixing. Improvements are made to the separation steps while still having the ability of adsorption and support, reducing the contact with the hard material of the glass plate 6 during the separation process and reducing damage to the glass plate 6.

[0062] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
