Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0025] The fixed ring seat 5 is annular, and the movable end of the support rod 3 means that the support rod 3 can rotate and slide. The sliding direction of the slider 8 is along the length direction of the support rod 3. The grinding device 10 is a prior art and can be a polishing grinder. It is vertically arranged, and the output end is a grinding head. The grinding head is arranged downward and abuts against the processing glass 15. The polishing and grinding function can be achieved by rotating the grinding head.

[0026] In the specific implementation, the position of the support rod 3 is adjusted first. By rotating the support rod 3, the support rod 3 can be positioned in the radial direction of the fixed ring seat 5 to form a Figure 4 In the state, the movable end of the support rod 3 can also be slid to make the support rod 3 in an eccentric structure relative to the fixed ring seat 5, forming a Figure 5 In the state, by adjusting the position of the support rod 3, the support rod 3 is first aligned with the scratch position of the glass to be processed 15 below it, and then the driving assembly and the grinding device 10 are started to make the slider 8 reciprocate along the support rod 3, so that the grinding device 10 reciprocates and polishes the glass to be processed 15, and finally the polishing and grinding treatment of the glass to be processed 15 is achieved to eliminate the scratches. Compared with the prior art, the present invention can make the grinding device 10 reciprocate linearly on the support rod 3 to evenly polish and grind the glass to be processed 15, and the multiple positions of the support rod 3 can be adjusted to adapt to different positions of the scratches on the glass to be processed 15, and the adaptability is high.

[0027] like Figure 1 、 Figure 4 The top of the fixed ring seat 5 is slidably connected to two arc-shaped seats 4, and the sliding direction of the two arc-shaped seats 4 is the circumferential direction of the fixed ring seat 5. The top of one of the arc-shaped seats 4 is rotatably connected to the first connecting head 20, and the top of the other arc-shaped seat 4 is rotatably connected to the second connecting head 21; the first connecting head 20 is fixedly connected to one end of the support rod 3, and the other end of the support rod 3 is slidably passed through the second connecting head 21, so that the support rod 3 can be located in the radial or eccentric distribution of the fixed ring seat 5.

[0028] The arc seat 4 is arc-shaped, and an arc groove is set at its bottom. It is nested on the top end face of the fixed ring seat 5 through the arc groove. Bearings, balls and other components can be set on the fixed ring seat 5 to reduce friction. The arc seat 4 slides along the circumferential direction of the fixed ring seat 5.

[0029] Both the first connector 20 and the second connector 21 are provided with through holes, and the two ends of the support rod 3 pass through the corresponding through holes. The first connector 20 and the second connector 21 realize the rotation of the support rod 3, among which the second connector 21 realizes the sliding of the support rod 3 and the extension when eccentric.

[0030] In specific implementation, the angle and position of the support rod 3 can be adjusted by sliding the two arc-shaped seats 4. During this process, the first and second connectors rotate, and the length of the support rod 3 passing through the second connector 21 changes.

[0031] Furthermore, the driving assembly includes a driving wheel 6, a driven wheel 22, a synchronous belt 7 and a motor. The driving wheel 6 and the driven wheel 22 are rotatably arranged at both ends of the support rod 3, and the axes of the driving wheel 6 and the driven wheel 22 are vertically arranged. The driving wheel 6 is arranged on the top of one end of the support rod 3 passing through the first connecting head 20, and the motor is installed at the bottom. The driving wheel 6 is connected to the output end of the motor, and the motor is fixedly installed on the support rod 3 through a bracket. The synchronous belt 7 is sleeved on the driving and driven wheels, the support rod 3 is located on the inner side of the synchronous belt 7, and one side of the synchronous belt 7 is connected to the slider 8.

[0032] Specifically, the side of the slider 8 is fixedly connected to the transition block 9, and the transition block 9 is fixedly connected to one side of the synchronous belt 7. The slider 8 can be reciprocated by the reciprocating rotation of the motor.

[0033] Furthermore, it also includes two positioning components, which are slidably arranged on the support rod 3, and the top of the positioning component contacts the top of the glass 15 to be processed. The slider 8 is located between the two positioning components, and the two positioning components are used to align the two ends of the scratch, thereby achieving the function of positioning the support rod 3.

[0034] The distance between the two positioning components constrains the reciprocating stroke of the slider 8. During implementation, the bottoms of the two positioning components are aligned with the two ends of the glass scratch, so that the support rod 3 is roughly aligned with the scratch, and then the number of revolutions of the motor is adjusted to control the movement stroke of the slider 8. When adjusting, the slider 8 is first moved to the positioning component on one side. At this time, the number of revolutions of the motor can be adjusted. When the motor rotates to a certain number of revolutions, the slider 8 moves to the other positioning component, and then the motor is reciprocated forward and reversed within the range of the number of revolutions, so that the slider 8 can be reciprocated between the two positioning components, so that the grinding device 10 can reciprocate. Grinding scratches, the positioning component of the present invention is to realize the positioning of the scratches, so that the support rod 3 is convenient for aligning the scratches, so that the reciprocating motion of the slider 8 and the grinding device 10 is on the scratch path, and the second is to constrain the stroke of the slider 8, and the stroke of the reciprocating motion is specifically set according to the length of the scratch. In the specific implementation, since the support rod 3 is above the glass to be processed 15, the two positioning components determine the direction of the scratch by a line determined by two points, which is more accurate and can avoid parallax during positioning. By constraining the stroke of the slider 8 by two positioning components, it can also be more intuitive and convenient to adapt to the path length of the scratch.

[0035] It should be noted that the present invention preferably performs polishing and grinding on linear scratches. For curved or bent scratches, a splitting method can be adopted to split them into multiple straight scratch segments for segmented processing. Alternatively, the grinding head at the output end of the grinding device 10 can be replaced with a larger diameter to cover the curvature of the scratch. The motor is preferably a servo motor in the prior art, and its control method is the prior art and can be controlled by a PLC microcontroller.

[0036] Specifically, the positioning component includes a positioning sleeve 12, a vertical rod 13 and a plug-in piece 11. The positioning sleeve 12 can be slidably mounted on the support rod 3. The bottom of the positioning sleeve 12 is fixedly connected to the top of the vertical rod 13, and the bottom of the vertical rod 13 contacts the top of the glass 15 to be processed; the support rod 3 is provided with waist-shaped holes distributed along the length direction of the support rod 3, and the top of the positioning sleeve 12 is provided with a plug-in groove connected to the waist-shaped hole. The plug-in piece 11 passes through the plug-in groove and is inserted into the waist-shaped hole. A clamping portion is provided on the side of the plug-in piece 11, and the inner wall surface of the waist-shaped hole is provided with a limiting portion matching the clamping portion to constrain the sliding of the positioning sleeve 12.

[0037] The support rod 3 is preferably a square steel tube structure, so as to constrain the circumferential rotation of the positioning sleeve 12 and the slider 8. In specific implementation, after sliding the positioning sleeve 12 on the two positioning components to the target position, the plug-in piece 11 is passed through the plug-in slot from top to bottom and inserted into the waist-shaped hole, so that the clamping part and the limiting part cooperate, and the positioning sleeve 12 can be constrained in the length direction of the support rod 3.

[0038] like Figure 3 , Figure 7 , the clamping part is a groove on the side surface of the insertion piece 11, and the limiting part is a convex tooth on the inner wall surface of the waist-shaped hole. A plurality of the convex teeth are distributed along the length direction of the support rod 3, and the plurality of convex teeth are equally spaced, forming a wavy or toothed structure. The convex teeth can be distributed on one or both inner wall surfaces of the waist-shaped hole. The groove of the insertion piece 11 is nested on the convex teeth to realize the constraint of the positioning sleeve 12 in the length direction of the support rod 3.

[0039] Furthermore, the fixed ring seat 5 is fixedly arranged on the table board 1. The top of the support table 2 is detachably connected to the bottom of the table board 1. The top of the support table 2 is an open structure. A hollow cavity for accommodating the glass to be processed 15 is formed between the opening of the support table 2 and the table board 1. An upper hollow part communicating with the inside of the fixed ring seat 5 is arranged on the table board 1.

[0040] The support table 2 is in a "U" - shaped structure and can be connected to the table board 1 by means of screws or buckles, etc. The bottom of the support table 2 is supported by several support legs. The two ends of the hollow cavity are open in the horizontal direction. In specific implementation, the glass to be processed 15 is slid into the hollow cavity and is located below the fixed ring seat 5.

[0041] Furthermore, a lower hollow part matching the upper hollow part is arranged on the support table 2. An upper feeding plate 14 is arranged in the lower hollow part. The upper feeding plate 14 is connected to the support table 2 by a lifting device 16. The glass to be processed 15 is arranged on the upper feeding plate 14.

[0042] The upper hollow part of the table board 1 and the lower hollow part of the support table 2 are the same in size and shape and are in corresponding positions, and are directly below the internal space of the fixed ring seat 5. The positioning component and the grinding device 10 pass through the upper and lower hollow parts from top to bottom. The lifting device 16 is a prior art, such as an electric slide rail, a cylinder, an electric cylinder, a hydraulic cylinder, etc. The lifting device 16 is installed on the support legs below the support table 2. In specific implementation, the lifting device 16 first lowers the upper feeding plate 14 to the lowest position to facilitate placing the glass to be processed 15 on the upper feeding plate 14, and then raises the upper feeding plate 14 to the highest position so that the upper feeding plate 14 is buckled into the lower hollow part and the glass to be processed 15 is located in the hollow cavity.

[0043] Furthermore, the upper feeding plate 14 is in the structure of a mesh plate, and insertion pieces are respectively inserted into a plurality of mesh holes thereof. The plurality of insertion pieces are distributed along the circumference of the glass to be processed 15 to restrict the horizontal movement of the glass to be processed 15.

[0044] The insertion pieces can be components such as screws and pins. The insertion pieces abut against the side surface of the glass to be processed 15 to limit its movement, so as to restrict the glass to be processed 15 in the horizontal direction and prevent the glass to be processed 15 from moving along with the grinding device 10 during grinding. Moreover, when the glass to be processed 15 is a special-shaped glass, for example Figure 6 The mesh plate structure of the loading plate 14 can also adapt to its shape, making it easier to fix the glass 15 to be processed.

[0045] During specific implementation, the position of the glass to be processed 15 on the loading plate 14 can be adjusted first so that the scratched area is located inside the fixed ring seat 5, which facilitates the subsequent adjustment of the position of the support rod 3. The projection outline of the internal space of the fixed ring seat 5 can be engraved on the loading plate 14, and the scratched area of ​​the glass to be processed 15 needs to be located within the coverage of the projection outline. The position of the scratch can also be roughly aligned with the support rod 3 in advance, thereby reducing the amount of operation for adjusting the position of the subsequent support rod 3.

[0046] Furthermore, the top of the grinding device 10 is fixedly connected to a slide plate 19, and a connecting rod 18 can slide through the slide plate 19. The top of the connecting rod 18 is fixedly connected to the bottom of the slider 8, and the bottom of the connecting rod 18 supports the slide plate 19. A spring 17 is mounted on the connecting rod 18.

[0047] The slide plate 19 is arranged horizontally and the connecting rod 18 is arranged vertically. Multiple connecting rods 18 can be arranged. The bottom of the connecting rod 18 can support the slide plate 19 through a nut. When the loading plate 14 moves from bottom to top to the highest position, the spring 17 is compressed, and the grinding head at the bottom of the grinding device 10 generates pressure on the glass to be processed 15, which can improve the grinding performance.

[0048] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
