Description

Technical Field

[0001] The present application relates to the field of lens grinding, and in particular to a single-sided grinding device and process for PPG glass. Background Art

[0002] After processing, the PPG glass needs to be ground and polished to ensure its surface flatness and smoothness.

[0003] At present, the way to grind PPG glass is usually to limit the PPG glass in the placement groove, and then the grinding wheel descends to grind the surface of the PPG glass. And the existing grinding device is equipped with multiple processing stations, which can grind multiple PPG glasses at the same time. However, in practice, the processed PPG glass will have multiple specifications, that is, the overall thickness is different. If multiple specifications of PPG glass are processed at the same time, the descending stroke of the grinding wheel will be different. On the existing grinding device, the descending stroke of all grinding wheels is synchronized and the same, which cannot adapt to the simultaneous processing of PPG glass of different thicknesses. That is, the existing grinding device can only process PPG glass of the same specification at the same time. When you want to process glass of other specifications, you need to adjust the descending stroke of the grinding wheel and then process it, which is inefficient. Summary of the invention

The descending stroke of the mounting plate is fixed. If PPG glass of different thickness specifications is processed, the corresponding grinding wheel will rise adaptively to ensure that all grinding wheels can abut against the surface of the corresponding PPG glass. Then the rotating sleeve is rotated to drive the grinding wheel to rotate, and the rotating disk is rotated at the same time to achieve grinding of the surface of the PPG glass. That is, the grinding device can grind PPG glass of different specifications, and there is no need to adjust the descending stroke of the mounting plate to change the descending stroke of the grinding wheel, which helps to improve processing efficiency; the lifting block and the lifting groove are plug-in matched to realize the coaxial rotation of the linkage rod and the rotating sleeve, and the lifting block and the lifting groove are slidably matched to realize the relative sliding of the linkage rod and the rotating sleeve.

[0008] By adopting the above technical solution, the descending stroke of the mounting plate is fixed. When processing PPG glass with a thicker thickness, after the mounting plate is lowered, the linkage rod will rise a certain distance accordingly to ensure that the grinding wheel abuts against the surface of the PPG glass. When the linkage rod rises, under the cooperation of the first ratchet and the second ratchet, the second sliding block will slide when the linkage rod rises to avoid the rise of the first sliding block. When the linkage rod finishes rising, the second reset spring acts and the second sliding block resets. At this time, due to the action of the first ratchet and the second ratchet, the linkage rod cannot fall. Subsequently, when the rotating sleeve rotates, the locking piece locks the second sliding block, that is, the first ratchet and the first ratchet are locked. The two ratchets remain engaged, and the second sliding block cannot rise or fall, thereby locking the first sliding block in the vertical direction; at this time, the rotating sleeve drives the linkage rod to rotate synchronously to realize the rotation of the grinding wheel, and during the rotation process, the linkage rod is effectively prevented from vertical movement, thereby ensuring the grinding effect; when the grinding is completed, the rotating sleeve gradually stops rotating, and the driving assembly drives the first sliding block to slide away from the second sliding block, and the locking member also releases the lock on the second sliding block, the first ratchet and the second ratchet disengage, and under the action of the first compression spring, the linkage rod is reset, and then under the action of the first reset spring, the first sliding block is reset.

[0009] Preferably, a first motor is fixedly mounted on the mounting plate, and an output shaft of the first motor is fixedly connected to the rotating disk.

[0010] By adopting the above technical solution, the first motor runs to drive the rotating disk to rotate, and the rotating disk drives the grinding wheel to rotate. At this time, the grinding wheel performs eccentric motion, thereby achieving grinding of the PPG glass surface.

A communicating groove is also provided at one end of the rotating sleeve located in the communicating groove and an abutting spring is provided, one end of the abutting spring is connected with the inner wall of the communicating groove, and the other end of the abutting spring is connected with the plug-in block; a locking groove is provided on the second sliding block, the annular rod passes through the locking groove, and the locking piece is provided with a wedge block, and the wedge block is integrally formed on the annular rod; when the annular rod slides, the wedge block enters the locking groove, and the locking block abuts against the inner wall of the locking groove to prevent the second sliding block from sliding in a direction away from the first sliding block.

[0014] By adopting the above technical scheme, in the initial state, under the action of the abutment spring, the plug-in block abuts against one end of the plug-in slot, and when the second motor is running, the second pulley will rotate. When the second pulley rotates, the plug-in block slides in the plug-in slot. At this time, the abutment spring is compressed into the connecting slot, and when the plug-in block abuts against the other end of the plug-in slot, the second pulley drives the rotating sleeve to rotate synchronously, thereby realizing the coaxial rotation of the second pulley and the rotating sleeve; when the plug-in block slides, the annular rod slides accordingly, and the wedge block enters the sliding slot of the second sliding block and abuts against the inner wall of the sliding slot, thereby locking the sliding of the second sliding block in the sliding slot, that is, the second sliding block cannot slide, and at this time the second ratchet on the second sliding block is meshed with the first ratchet on the first sliding block, ensuring that the linkage rod cannot be lifted or lowered, which helps to reduce radial movement during the grinding process.

[0015] Preferably, a mounting groove is further provided in the rotating sleeve, the mounting groove is communicated with the annular groove, the rotating sleeve is located in the mounting groove and is rotatably connected to the first connecting shaft and the second connecting shaft, the rotation axes of the first connecting shaft and the second connecting shaft are both horizontal and perpendicular to each other, a linkage gear and a first bevel gear are coaxially fixed on the first connecting shaft, and a second bevel gear is coaxially fixed on the second connecting shaft; a sliding groove is provided on the annular rod, the annular rod is located in the sliding groove and is slidably connected to the first rack, the annular rod is located in the sliding groove and is provided with an avoidance spring, one end of the avoidance spring is connected to the inner wall of the sliding groove, the other end of the avoidance spring is connected to the first rack, the first rack and the linkage gear mesh with each other The first rack is provided with a plurality of first helical teeth, the linkage gear is provided with second helical teeth, and the first bevel gear and the second bevel gear are meshed; the driving assembly includes a driving gear and a second rack, the driving gear is coaxially fixed on the second connecting shaft, a vertical groove is provided in the vertical direction on the side of the first sliding block away from the first ratchet tooth, the second rack is slidably arranged in the vertical groove, the second rack is horizontally arranged and located below the driving gear, the first sliding block is provided with a second compression spring in the vertical groove, the second compression spring is located below the second rack, one end of the second compression spring is connected to the inner wall of the vertical groove, and the other end of the second compression spring is connected to the second rack.

[0016] By adopting the above technical solution, the second pulley rotates, the plug-in block slides in the plug-in groove and moves to the end of the plug-in groove, and then drives the rotating sleeve to rotate together. When the plug-in block moves in the plug-in groove, it drives the annular rod to slide. On the one hand, the wedge block of the annular rod enters the locking groove of the second sliding block to lock the second sliding block; on the other hand, when the annular rod slides, the first rack moves accordingly. Because the second sliding block locks the first sliding block, the first sliding block cannot slide, and the first rack will slide into the sliding groove to avoid the linkage gear; when the grinding is completed, under the action of the abutment spring, the plug-in block is reset, and the annular rod slides accordingly. On the one hand, the annular rod drives the wedge block to disengage from the locking groove to release the lock of the second sliding block; on the other hand, the annular rod drives the first rack to slide, and the first rack drives the linkage gear When the movable gear rotates, the linkage gear drives the first bevel gear to rotate through the first connecting shaft, and the first bevel gear drives the driving gear to rotate through the second bevel gear, and the driving gear drives the first sliding block to slide in the accommodating groove through the second rack, so that the first ratchet tooth and the second ratchet tooth are disengaged, and then under the action of the first compression spring, the linkage rod moves downward and resets. After the linkage rod is reset, the second rack and the driving gear just disengage. After disengagement, under the action of the first reset spring, the first sliding block is reset; in practice, in the initial state, the second rack and the driving gear are not meshed. When the linkage rod rises, the driving gear is meshed with the second rack, and because the second rack slides in the vertical groove, the second compression spring supports it, which can ensure that the driving gear and the second rack are in a meshing state, so as to ensure that the subsequent rotation of the driving gear can drive the first sliding block to slide.

[0017] Preferably, a screw slide is mounted on the base in a vertical direction, and the mounting plate is mounted on the slide of the screw slide.

[0018] By adopting the above technical solution, the screw slide operates to realize the lifting and lowering of the mounting plate in the vertical direction.

Place the PPG glass into the placement slot, the mounting plate descends, and the grinding wheel abuts against the surface of the PPG glass. If the thickness of the PPG glass is different, the corresponding linkage rod will rise adaptively before the mounting plate descends to ensure that all grinding wheels abut against the corresponding PPG glass surface. That is, the grinding device can grind PPG glass of different specifications at the same time, which helps to improve the grinding efficiency. 2. The second motor drives the second pulley to rotate through the first pulley and the belt. When the second pulley rotates, it will first rotate relative to the rotating sleeve, and the plug-in block slides in the plug-in slot until the plug-in block moves to the other end of the plug-in slot. Then the second pulley drives the rotating sleeve to rotate synchronously. When the plug-in block slides in the plug-in slot, it drives the annular rod to slide. On the one hand, the wedge block of the annular rod enters the locking slot of the second sliding block to lock the second sliding block; on the other hand, when the annular rod slides, the first rack moves accordingly. Because the second sliding block locks the first sliding block, the first sliding block cannot slide, and the first rack will slide to the sliding slot When the grinding is completed, the plug-in block is reset under the action of the abutment spring, and the annular rod slides accordingly. On the one hand, the annular rod drives the wedge block to disengage from the locking groove, thereby releasing the lock on the second sliding block. On the other hand, the annular rod drives the first rack to slide, and the first rack drives the linkage gear to rotate. The linkage gear drives the first bevel gear to rotate through the first connecting shaft, and the first bevel gear drives the driving gear to rotate through the second bevel gear. The driving gear drives the first sliding block to slide in the accommodating groove through the second rack, so that the first ratchet and the second ratchet are disengaged. Subsequently, under the action of the first compression spring, the linkage rod moves downward and resets. BRIEF DESCRIPTION OF THE DRAWINGS

In practice, the shape of the PPG glass is circular; a screw slide 11 is mounted on the base 1 in a vertical direction, and a mounting plate 12 is fixedly mounted on the slide of the screw slide 11, that is, the mounting plate 12 is lifted and lowered on the base 1, and a plurality of rotating disks 3 are rotatably arranged on the lower side of the mounting plate 12, and a rotating sleeve 4 is rotatably arranged on the lower side of the rotating disk 3, and the rotation axis of the rotating sleeve 4 is misaligned with the rotation axis of the rotating disk 3, and a linkage rod 5 is lifted and lowered in the rotating sleeve 4, and the linkage rod 5 rotates coaxially with the rotating sleeve 4, and a grinding wheel 6 is fixedly connected to the lower end of the linkage rod 5; the linkage rod 5 rises adaptively in the rotating sleeve 4.

[0026] The PPG glass is placed into the placement groove 21, and the screw slide 11 drives the mounting plate 12 to descend, so that the grinding wheel 6 and the surface of the PPG glass are in contact. If PPG glass of different specifications is to be handled, the descending stroke of the mounting plate 12 remains unchanged. After the grinding wheel 6 is in contact with the PPG glass, when the mounting plate 12 continues to descend, the linkage rod 5 will adaptively rise relative to the rotating sleeve 4 to ensure that the grinding wheel 6 is in contact with the PPG glass; then the rotating sleeve 4 rotates to drive the grinding wheel 6 to rotate, and the rotating disk 3 also rotates synchronously to realize the grinding operation of the PPG glass; that is, the grinding device can grind PPG glass of different thickness specifications without changing the descending stroke of the mounting plate 12, which helps to improve processing efficiency.

When the first motor 13 is running, the rotating disk 3 can be rotated, and when the second motor 31 is running, the rotating sleeve 4 can be rotated through the first pulley 32, the second pulley 33 and the belt 34, thereby realizing the rotation of the grinding wheel 6; when the rotating disk 3 rotates, the grinding wheel 6 will make an eccentric movement with the rotating disk 3, the diameter of the grinding wheel 6 is larger than the radius of the glass, and the moving track of the grinding wheel 6 can cover all positions on the surface of the PPG glass.

[0028] Reference Figure 2 and Figure 3A lifting block 51 is integrally formed on the circumference of the linkage rod 5, and a lifting groove 41 is provided on the inner wall of the rotating sleeve 4 in the vertical direction. The lifting block 51 is plugged into the lifting groove 41, and the lifting block 51 and the lifting groove 41 form a sliding fit in the vertical direction; a first compression spring 411 is provided in the rotating sleeve 4, and the first compression spring 411 is vertically arranged and located above the linkage rod 5, one end of the first compression spring 411 is connected to the linkage rod 5, and the other end is connected to the inner wall of the rotating sleeve 4. The plugging of the lifting block 51 and the lifting groove 41 realizes the coaxial rotation of the linkage rod 5 and the rotating sleeve 4, and the sliding fit of the lifting block 51 and the lifting groove 41 realizes the relative sliding of the linkage rod 5 and the rotating sleeve 4.

[0029] Reference Figure 2 and Figure 4 A receiving groove 52 is provided in the middle of the linkage rod 5. The linkage rod 5 is located in the receiving groove 52 and is slidably connected to the first sliding block 7. A first return spring 53 is provided in the receiving groove 52 of the linkage rod 5. The length direction of the first return spring 53 is consistent with the sliding direction of the first sliding block 7. One end of the first return spring 53 is connected to the inner wall of the receiving groove 52, and the other end is connected to the first sliding block 7. A plurality of first ratchet teeth 71 are distributed along the vertical direction on one side of the first sliding block 7. The first ratchet teeth 71 are arranged obliquely downward.

A second return spring 421 is provided in the sliding groove 42 of the rotating sleeve 4. The length direction of the second return spring 421 is consistent with the sliding direction of the second sliding block 8. One end of the second return spring 421 is connected to the inner wall of the sliding groove 42, and the other end is connected to the second sliding block 8.

The rotating sleeve 4 is provided with a driving assembly 9 for driving the first sliding block 7 to slide, and a locking member for locking the second sliding block 8 is also provided in the rotating sleeve 4.

[0030] When processing PGG glass with a larger thickness, after the mounting plate 12 is lowered, the linkage rod 5 will slide upward relative to the rotating sleeve 4. When the linkage rod 5 slides, under the action of the first ratchet 71 and the second ratchet 81, the second sliding block 8 slides to avoid the rise of the first sliding block 7. When the linkage rod 5 finishes rising, under the action of the second reset spring 421, the second sliding block 8 is reset, and the first ratchet 71 and the second ratchet 81 remain in a meshing state; then the rotating sleeve 4 rotates, and the locking member locks the second sliding block 8, and the second sliding block 8 cannot slide. At this time, the first sliding block 7 cannot be lifted or lowered relative to the rotating sleeve 4 due to the action of the ratchet teeth; during the grinding process, vibration and movement will occur, that is, the first sliding block 7 may be lifted or lowered relative to the rotating sleeve 4, affecting the grinding effect. The locking of the second sliding block 8 is used to achieve the locking of the first sliding block 7, which helps to prevent the first sliding block 7, i.e., the linkage rod 5, from slipping. When the grinding is completed, the rotating sleeve 4 gradually stops rotating, and the driving assembly 9 drives the first sliding block 7 to slide in the direction away from the second sliding block 8, and the first ratchet 71 and the second ratchet 81 are disengaged. Under the action of the first compression spring 411, the linkage rod 5 slides downward quickly to reset, and then the first reset spring 53 acts, and the first sliding block 7 is reset again.

The plug-in block 331 is plugged into the plug-in groove 43, and the plug-in block 331 slides in the plug-in groove 43. In practice, the second pulley 33 and the rotating sleeve 4 rotate in cooperation.

The locking piece is configured as a wedge block 101, and the wedge block 101 is integrally formed on the annular rod 10. When the annular rod 10 slides, the wedge block 101 enters the locking groove 82, and the wedge block 101 abuts against the inner wall of the locking groove 82 to lock the second sliding block 8, thereby preventing the second sliding block 8 from sliding in a direction away from the first sliding block 7.

[0033] In the initial state, under the action of the abutment spring 46, the plug-in block 331 abuts against one end of the plug-in slot 43. When the second pulley 33 rotates, the second pulley 33 will first rotate relative to the rotating sleeve 4, and the plug-in block 331 slides in the plug-in slot 43. The abutment spring 46 is compressed and enters the connecting slot 45. When the plug-in block 331 moves to the other end of the plug-in slot 43, the second pulley 33 drives the rotating sleeve 4 to rotate synchronously; when the plug-in block 331 slides, it drives the annular rod 10 to slide, and the wedge block 101 enters the locking slot 82 to lock the second sliding block 8. Through the action of the first ratchet 71 and the second ratchet 81, the first sliding block 7 can be locked, that is, the linkage rod 5 is prevented from lifting and lowering, and the grinding wheel 6 is prevented from radially moving during the grinding process, thereby affecting the grinding effect.

The first sliding block 7 is located in the vertical groove 72 and is provided with a second compression spring 74. The second compression spring 74 is vertically arranged and located below the second rack 92. One end of the second compression spring 74 is connected to the inner wall of the vertical groove 72, and the other end is connected to the second rack 92.

[0037] The second pulley 33 rotates, and the plug-in block 331 first slides in the plug-in groove 43. In this process, the plug-in block 331 drives the annular rod 10 to slide. On the one hand, the second sliding block 8 can be locked. On the other hand, the annular rod 10 drives the first rack 103 to slide. When the first rack 103 slides, the first sliding block 7 cannot slide to the side of the second sliding block 8, that is, the linkage gear 201 cannot rotate. Under the cooperation of the first bevel tooth 1031 and the second bevel tooth 2011, the first rack 103 will slide into the sliding groove 102 to avoid the linkage gear 201; when the grinding is completed, under the action of the abutment spring 46, the plug-in block 331 is reset, and the annular rod 10 slides accordingly. On the one hand, the wedge block 101 and the locking groove 82 are disengaged. , releasing the lock on the second sliding block 8; on the other hand, the first rack 103 slides in the opposite direction, driving the linkage gear 201 to rotate, and the linkage gear 201 drives the first bevel gear 202 to rotate through the first connecting shaft 20, and the first bevel gear 202 drives the driving gear 91 to rotate through the second bevel gear 301, and the driving gear 91 drives the second rack 92 to move, that is, drives the second sliding block 8 to slide in the direction away from the first sliding block 7, so that the first ratchet 71 and the second ratchet 81 are disengaged, and then under the action of the first compression spring 411, the linkage rod 5 slides downward quickly to reset, and after resetting, the second rack 92 and the driving gear 91 are just disengaged, and after disengagement, under the action of the first reset spring 53, the first sliding block 7 is reset.

[0038] In practice, in the initial state, the second rack 92 is not meshed with the driving gear 91. When the linkage rod 5 rises, the driving gear 91 is meshed with the second rack 92. Since the second rack 92 slides in the vertical groove 72, the second compression spring 74 supports it, thereby ensuring that the driving gear 91 and the second rack 92 are in a meshing state, so as to ensure that the subsequent rotation of the driving gear 91 can drive the first sliding block 7 to slide.

[0039] The implementation principle of a single-sided processing and grinding device for PPG glass in the embodiment of the present application is as follows: the PPG glass is placed in the placement groove 21 of the placement plate 2, and the mounting plate 12 drives the grinding wheel 6 to descend. The descending stroke of the mounting plate 12 is fixed. After the grinding wheel 6 abuts against the PPG glass, it will move upward a certain distance relative to the rotating sleeve 4, and the grinding wheel 6 rises, and the driving gear 91 is meshed with the second rack 92. For PPG glasses of different thickness specifications, the distances by which the grinding wheel 6 rises relative to the rotating sleeve 4 are different; then the second motor 31 drives the second pulley 33 to rotate, and the second pulley 33 first rotates relative to the rotating sleeve 4, that is, the plug-in block 331 slides in the plug-in groove 43, and the plug-in block 331 drives the annular rod 10 to slide, and the wedge block 101 enters the locking groove 82 to lock the second sliding block 8. When the plug-in block 331 moves to the other end of the plug-in groove 43, the second pulley 33 drives the rotating sleeve 4 to rotate synchronously to realize the rotation of the grinding wheel 6 The first motor 13 drives the rotating disk 3 to rotate, and the first motor 13 drives the rotating disk 3 to rotate, so that the grinding wheel 6 can grind the PPG glass; after the grinding is completed, the second pulley 33 stops rotating, the spring 46 acts, the plug-in block 331 resets, and drives the annular rod 10 to slide in the direction. On the one hand, the wedge block 101 disengages from the locking groove 82 to release the lock on the second sliding block 8. On the other hand, the first rack 103 drives the linkage gear 201 to rotate, and finally drives the driving gear 91 to rotate, and the driving gear 91 drives the second rack 92 to slide, that is, drives the first sliding block 7 to slide in the direction away from the second sliding block 8, so that the first ratchet 71 and the second ratchet 81 are disengaged. Under the action of the first compression spring 411, the linkage rod 5 quickly moves downward and resets to restore the initial state. The grinding device of the present application can be used to grind PPG glasses of different thickness specifications without adjusting the descending stroke of the mounting plate 12, thereby improving the grinding efficiency.
