In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] Please refer to Figures 1 to 5 , this embodiment provides a glass grinding device. The glass grinding device includes a grinding wheel 310. A wheel groove 311 is formed along the circumferential direction of the grinding wheel 310. The edge of the glass can extend into the wheel groove 311, and the grinding wheel 310 can rotate around its axis to grind the edge of the glass.

[0035] Similar to the prior art, the grinding wheel 310 can not only rotate about its axis but also move in a linear direction. Exemplarily, in this embodiment, the glass grinding device includes two grinding wheels 310. The two grinding wheels 310 are arranged at intervals in the first direction, and the distance between the two grinding wheels 310 is adjustable. Both of the two grinding wheels 310 can move in the second direction perpendicular to the first direction. The carrier glass 100 can be placed between the two grinding wheels 310, and the length direction of the carrier glass 100 is parallel to the second direction, so that the two grinding wheels 310 can respectively grind the two long sides of the carrier glass 100. After grinding the two long sides of the carrier glass 100, the distance between the two grinding wheels 310 is adjusted, and the position of the carrier glass 100 is adjusted. Specifically, the carrier glass 100 is rotated by 90°, so that the width direction of the carrier glass 100 is parallel to the second direction. After that, the two grinding wheels 310 can respectively grind the two short sides of the carrier glass 100.

[0036] Of course, in other alternative embodiments, four grinding wheels 310 can also be provided, and the four grinding wheels 310 respectively grind the four edges of the carrier glass 100. Or, in other alternative embodiments, only one grinding wheel 310 can be provided, and the grinding wheel 310 can move along the contour of the carrier glass 100, so as to grind the four edges of the carrier glass 100 in sequence. No specific limitation is made in this embodiment.

[0037] In addition to the grinding wheel 310, the glass grinding device in this embodiment further includes a clamp 321 and a driving mechanism 322. Among them, the clamp 321 is configured to clamp the repair stone 200, and the driving mechanism 322 is configured to drive the repair stone 200 to move in a direction perpendicular to the axial direction of the grinding wheel 310, so that the repair stone 200 can be moved into the wheel groove 311. When the repair stone 200 is moved into the wheel groove 311, as the grinding wheel 310 rotates, mutual friction occurs between the repair stone 200 and the groove wall of the wheel groove 311. Moreover, as the repair stone 200 gradually wears, the driving mechanism 322 always controls the feeding of the repair stone 200, so as to repair the groove wall of the wheel groove 311.

[0038] Based on the above, in this embodiment, the driving mechanism 322 drives the repair stone 200 to move. Therefore, this embodiment can accurately control the feeding speed of the repair stone 200, the pressure exerted by the repair stone 200 on the grinding wheel 310, the angle between the moving direction of the repair stone 200 and the axial direction of the grinding wheel 310, and the feeding amount of the repair stone 200, so as to ensure that the repair effect of each repair is consistent, and further ensure that the defects of the grinding wheel 310 can be eliminated in each repair. In addition, this embodiment can realize the automatic repair of the groove wall of the wheel groove 311, thus eliminating the safety hazards to the staff and improving the repair efficiency, and further improving the production efficiency of the carrier glass 100.

[0039] Specifically, in this embodiment, the chuck 321 and the driving mechanism 322 form a repair module 320. The repair module 320 is arranged at the repair station. Based on the above, the glass grinding device in this embodiment includes two grinding wheels 310. Correspondingly, the glass grinding device is provided with two repair stations, and the repair module 320 is arranged at both repair stations. During the process of the grinding wheel 310 grinding the carrier glass 100, when the grinding wheel 310 moves a preset stroke in the second direction, the grinding wheel 310 moves to the repair station for repair operations. When the grinding wheel 310 is at the repair station, the driving mechanism 322 drives the chuck 321 to move in a direction perpendicular to the axial direction of the grinding wheel 310 to repair the groove wall of the wheel groove 311. After the repair is completed, the grinding wheel 310 resumes grinding the carrier glass 100.

[0040] Moreover, after multiple repair operations, it is necessary to replace the repair stone 200. Exemplarily, each time it is necessary to replace the repair stone 200 clamped by the chuck 321, the driving mechanism 322 drives the chuck 321 to move to the first limit position. After that, when the grinding wheel 310 moves to the repair station for repair, the driving mechanism 322 drives the chuck 321 to move a first preset stroke towards the grinding wheel 310. Taking the first preset stroke as 5 mm as an example, each time it is necessary to replace the repair stone 200 clamped by the chuck 321, when the grinding wheel 310 first moves to the repair station, the driving mechanism 322 drives the chuck 321 to move 5 mm, so that the repair stone 200 moves into the wheel groove 311 and repairs the groove wall of the wheel groove 311. After the repair is completed, the driving mechanism 322 drives the chuck 321 to retreat a second preset stroke. When the grinding wheel 310 moves to the repair station next time, the driving mechanism 322 drives the chuck 321 to move 5 mm towards the grinding wheel 310 again. Based on the above, taking the second preset stroke as 3 mm as an example, the length of the worn part of the repair stone 200 for each repair operation is 2 mm, so as to ensure that the repair effect of each repair is consistent, and further ensure that each repair can eliminate the defects of the grinding wheel 310.

[0041] In addition, it is worth noting that for manual repair, the staff needs to hold the repair stone 200 to repair the groove wall of the wheel groove 311. Moreover, for the convenience of the staff's operation, a relatively long part needs to be reserved on the repair stone 200 for the staff to hold. Therefore, a large amount of the repair stone 200 remains unconsumed after each repair operation. When the staff performs the next repair operation, for the convenience of the staff's operation, the repair stone 200 that was not consumed last time is directly discarded, and the staff holds a new repair stone 200 for repair, resulting in relatively serious waste of resources. In this embodiment, the chuck 321 clamps the repair stone 200, and the chuck 321 only needs to clamp a relatively short part of the repair stone 200. Moreover, the same repair stone 200 can be used for multiple repair operations, thus saving resources.

[0042] It can be understood that the clip 321 can be selected as a snap or a claw, etc., and no specific limitation is made in this embodiment. In addition, since the specific structure of the clip 321 is prior art, it will not be elaborated in this embodiment.

[0043] Further, the glass grinding device further includes a first shield 330. The first shield 330 covers the outer periphery of the grinding wheel 310. The first shield 330 can move together with the grinding wheel 310. The first shield 330 is provided with a first opening 331 and a second opening 332. The edge of the carrier glass 100 can extend into the wheel groove 311 through the first opening 331. As the grinding wheel 310 moves along the second direction and rotates about its axis, the grinding wheel 310 rolls along the edge of the carrier glass 100, thereby grinding the edge of the carrier glass 100. The first shield 330 can prevent the waste chips generated during grinding from splashing onto other parts of the carrier glass 100 during the process of grinding the carrier glass 100. When the grinding wheel 310 is located at the repair station, the second opening 332 is aligned with the repair stone 200, and the repair stone 200 can be moved into the wheel groove 311 through the second opening 332. Specifically, the driving mechanism 322 can drive the repair stone 200 to move into the first shield 330 through the second opening 332 and into the wheel groove 311.

[0044] In addition, a nozzle 333 is provided in the first shield 330. The nozzle 333 is configured to spray water towards the joint position of the grinding wheel 310 and the carrier glass 100 when the grinding wheel 310 grinds the carrier glass 100, so as to dissipate heat during the grinding process.

[0045] Based on the above-mentioned content, the glass grinding device further includes a baffle 340. The baffle 340 has a first working position covering one side of the second opening 332 and a second working position away from the second opening 332. During the process of grinding the carrier glass 100, the baffle 340 is located at the first working position, so as to prevent the waste water from spraying out through the second opening 332. After the grinding wheel 310 moves to the repair station, the baffle 340 can be switched from the first working position to the second working position, so that the repair stone 200 can be moved into the first shield 330.

[0046] Exemplarily, in this embodiment, the baffle 340 is a film made of a soft material, and one side of the baffle 340 is fixedly connected to the first shield 330. When the driving mechanism 322 drives the repair stone 200 to move towards the grinding wheel 310, the repair stone 200 can push open the baffle 340, so that the baffle 340 is switched from the first working position to the second working position. After that, the repair stone 200 can be moved into the first shield 330.

[0047] Of course, in other alternative embodiments, the baffle 340 may also be a rigid plate capable of moving in a straight line direction. The baffle 340 can move between a first working position and a second working position, and this embodiment does not make specific limitations on this.

[0048] Further, the glass grinding device further includes a mounting plate 323. The driving mechanism 322 includes a slider 3221 and a driving member 3222. The slider 3221 is slidably connected to the mounting plate 323, and the clamp 321 is fixedly connected to the slider 3221. The driving member 3222 is configured to drive the slider 3221 to reciprocate in a direction perpendicular to the axial direction of the grinding wheel 310, so as to drive the clamp 321 to advance a first preset stroke and retreat a second preset stroke. Based on the above-mentioned content, both repair modules 320 include a mounting plate 323.

[0049] Optionally, in this embodiment, the driving member 3222 is a servo motor, so as to accurately control the moving distance of the clamp 321. Correspondingly, a lead screw 3223 is fixedly connected to the movable end of the driving member 3222, and the slider 3221 is screwed to the lead screw 3223. The driving member 3222 can drive the lead screw 3223 to rotate, so as to drive the slider 3221 to move in a direction perpendicular to the axial direction of the grinding wheel 310.

[0050] Furthermore, a guide rail 3231 is fixedly connected to the mounting plate 323. The guide rail 3231 is provided with a chute 32311, and the chute 32311 extends in a direction perpendicular to the axial direction of the grinding wheel 310. The slider 3221 is slidably connected to the chute 32311, so as to accurately control the feeding direction of the repair stone 200.

[0051] Moreover, a guide block 32313 is provided at one end of the guide rail 3231 away from the driving member 3222. A guide hole (not shown in the figure) is provided on the guide block 32313. The driving member 3222 can drive the repair stone 200 to pass through the guide block 32313 and move into the wheel groove 311. The guide block 32313 is used to guide the repair stone 200, so as to further accurately control the feeding direction of the repair stone 200.

[0052] In addition, the glass grinding device further includes a second shield 324. The second shield 324 covers the outer periphery of the guide rail 3231, so as to protect the chute 32311 from external pollution, and further accurately control the feeding direction of the repair stone 200. Based on the above-mentioned content, both repair modules 320 include a second shield 324.

[0053] Based on the above, a blow pipe 32312 is provided on the guide rail 3231. The blow pipe 32312 is configured to blow air into the chute 32311, so as to further protect the guide rail 3231 from being polluted by the chute 32311, and further accurately control the feeding direction of the repair stone 200.

[0054] In addition, based on the content described above, when the remaining repair stone 200 is insufficient to complete the next repair operation after multiple repair operations, it is necessary to replace the repair stone 200 clamped by the clamp 321. At this time, the clamp 321 is located at the second limit position. When it is necessary to replace the repair stone 200, the drive mechanism 322 needs to drive the clamp 321 to move to the first limit position. That is, the first limit position and the second limit position are the two limit positions of the clamp 321. In this embodiment, a position detection mechanism is installed on the guide rail 3231. The position detection mechanism is configured to detect the position of the slider 3221, so as to detect whether the position of the clamp 321 moves to the first limit position and the second limit position. That is, the detection mechanism is used to detect whether the clamp 321 moves to the two limit positions, so as to further ensure that the repair effect of each repair is consistent.

[0055] Exemplarily, in this embodiment, the detection mechanism includes a first photoelectric sensor 32314 and a second photoelectric sensor 32315. Among them, the first photoelectric sensor 32314 detects whether the clamp 321 moves to the first limit position by detecting the position of the slider 3221, and the second photoelectric sensor 32315 detects whether the clamp 321 moves to the second limit position by detecting the position of the slider 3221.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
