Description

Technical Field

[0001] The invention relates to the technical field of lens cutting, in particular to an optical lens cutting and positioning device. Background Art

[0002] Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks.

[0003] Eyeglass lens cutting equipment is mainly used for cutting and processing eyeglass lenses. This equipment usually includes laser cutting machines, mechanical cutting machines and manual cutting tools.

[0037] like Figure 7 The supporting component 2 includes an input tube 35, an alignment device 36 and a power device 37. The input tube 35 is symmetrically fixedly installed on the top of the alignment device 36. The alignment device 36 is fixedly installed at the top front end of the power device 37, which can support the input tube 35 to store the optical lens 3.

[0038] like Figure 8 The alignment device 36 includes a shovel plate 38, a second gear 39, a first rack 40, a second magnetic sheet 41 and an extension bracket 42. The second gear 39 is rotatably mounted on the front end of the extension bracket 42. The first rack 40 is meshed at the top and bottom ends of the second gear 39. The shovel plate 38 is fixedly mounted on the rear end of the first rack 40. The second magnetic sheet 41 is fixedly mounted on the rear end of the first rack 40 below the second gear 39. When the second magnetic sheet 41 moves toward the rear end and disengages from the first magnetic sheet 26, the shovel plate 38 at the bottom end of the second gear 39 will fit against the inner wall of the input tube 35 to prevent the first rack 40 from disengaging from the second gear 39.

[0039] like Fig. 9The power device 37 includes a receiving cavity 43, a blocking plate 44, a cutting device 45, a second rack 46, a driving motor 47, a threaded rod 48 and a positioning base 49. The second rack 46 is fixedly mounted at the centers of both sides of the positioning base 49. The driving motor 47 is fixedly mounted on the front end of the positioning base 49. The threaded rod 48 rotates through the positioning base 49 and is fixedly connected to the rear end center of the driving motor 47. The cutting device 45 is fixedly mounted at the top rear end of the positioning base 49. The receiving cavity 43 is fixedly mounted on the rear end of the positioning base 49, and the receiving cavity 43 is located below the rear end of the cutting device 45. The blocking plate 44 is fixedly mounted at the top rear end of the receiving cavity 43, and is slidably sleeved on the sliding rods on both sides of the inside of the positioning base 49 through the bottom end of the positioning substrate 19, so that the positioning substrate 19 can be supported to move in a straight line.

[0040] The connecting frame 13 is fixedly mounted on the rear ends of both sides of the positioning base plate 19, the end of the first spring 9 facing away from the winding wheel 12 is connected to the front ends of both sides of the positioning base plate 19, the supporting cross frame 8 is slidably sleeved on the first guide rail 22, the vertical plate 25 is threadedly sleeved on the threaded rod 48, the input cylinder 35 is fixedly mounted on the opposite end of the extension bracket 42, the extension bracket 42 is fixedly mounted on both sides of the positioning base 49 close to the first rack 40, the jet equipment 6 and the grinding equipment 7 are both electrically connected to the plug 16, the contact guide plate 14 is horizontally aligned with the limit plate 27, the two sides of the rear end of the extrusion block 24 are inclined at 45°, the front end of the opposite end of the support fence 28 is inclined at 45°, and the interior of the positioning base plate 19 is provided with a supporting cross frame. The guide plate 20 has a displacement groove adapted to the frame 8, the transverse guide rod 23 and the extrusion block 24 are offset up and down, the top of the guide plate 20 is set at a 45° slope on both sides, the interior of the U-shaped air cylinder 34 is set in a hollow state, and a closed cavity is formed between the first piston rod 30, the U-shaped air cylinder 34 and the second piston rod 33, a key is fixedly installed on the side end of the first rack 40 away from the second gear 39, and a card groove is provided inside the top and bottom ends of the extension bracket 42, and the rear end surface of the shovel plate 38 is set at a 20° inclination. When the optical lens 3 falls from the input cylinder 35 to the supporting railing 28, the bottom end of the grinding device 7 will be 5 mm away from the top of the optical lens 3, so that the grinding device 7 can grind the surface of the optical lens 3 when moving to the rear end.

[0041] The working principle of the embodiment 1 is as follows: when in use, the optical lens 3 is first placed into the input tube 35 in sequence, and when the second gear 39 is kept in a normal state, the shovel plate 38 at the bottom end of the second gear 39 will be located at the bottom end of the input tube 35, so that the optical lens 3 inside the input tube 35 can be prevented from falling downwards. At the same time, the driving motor 47 can be started to drive the threaded rod 48 to rotate, and the vertical plate 25 is threadedly sleeved on the threaded rod 48, so that when the threaded rod 48 rotates, the vertical plate 25 can drive the front end of the positioning base plate 19 to move. When the positioning base plate 19 is rotated, the vertical plate 25 can be used to drive the front end of the positioning base plate 19 to move. When the plate 19 moves toward the front end, the first magnetic sheet 26 can be driven to contact the second magnetic sheet 41. When the second magnetic sheet 41 is squeezed, the first rack 40 at the bottom of the second gear 39 can be driven to move at the bottom of the second gear 39, so that the second gear 39 can be driven to rotate, causing the first rack 40 above the second gear 39 to move toward the inside of the input cylinder 35, and the first rack 40 can be supported to move in a straight line by sliding the key on the end of the first rack 40 away from the second gear 39 in the slot inside the extension bracket 42;

[0042] At this time, the gap between the two shovel plates 38 is consistent with the thickness of the optical lens 3, and the rear end surface of the shovel plate 38 is inclined at 20 degrees, so that when the shovel plate 38 above the second gear 39 is inserted into the input tube 35, the optical lens 3 can be separated, so that only one optical lens 3 can be transmitted inside the input tube 35 at a time. At the same time, when the positioning substrate 19 moves to the front end to the limit position, the support fence 28 can be vertically aligned with the bottom end of the input tube 35, and the shovel plate 38 at the bottom end of the second gear 39 can be removed from the inside of the input tube 35. At this time, the optical lens 3 will fall accurately on the support fence 28, completing the loading of the optical lens 3;

[0043] Afterwards, the driving motor 47 can be started again to drive the threaded rod 48 to rotate in the opposite direction, so that the positioning substrate 19 can move toward the rear end. When the positioning substrate 19 moves toward the rear end, the first magnetic sheet 26 and the second magnetic sheet 41 are adsorbed, so that when the positioning substrate 19 moves toward the rear end, the first rack 40 at the bottom of the second gear 39 can be driven to move toward the rear end, so that the shovel plate 38 on the second gear 39 can be drawn out from the inside of the input tube 35, and the shovel plate 38 under the second gear 39 can be blocked under the input tube 35, so that the optical lens 3 inside the input tube 35 can be prevented from moving downward;

[0044] At the same time, when the positioning substrate 19 moves, the winding wheel 12 can be driven to mesh with the second rack 46, so that the winding wheel 12 can drive the first gear 11 to rotate, and when the first gear 11 rotates, the supporting cross frame 8 can be pulled to move to the rear end through the connecting rope 10. At this time, when the supporting cross frame 8 moves to the rear end, the contact guide plate 14 can be driven to disengage from the limit plate 27, and the elasticity of the second spring 17 can drive the plug 16 to be inserted into the inside of the socket 15, so that the grinding device 7 and the jet device 6 can be turned on at the same time. When the grinding device 7 moves inside the positioning substrate 19, it can pass through the top of the optical lens 3, so that the optical lens 3 can be polished, and the polished waste residue can be cleaned by the jet device 6, so that the waste residue can be prevented from accumulating on the top of the optical lens 3. When the winding wheel 12 passes over the second rack 46, the winding wheel 12 will lose its meshing force;

[0045] At this time, the elasticity of the first spring 9 will drive the support cross frame 8 to move to the front end until the support cross frame 8 is reset, driving the contact guide plate 14 to contact the limit plate 27 again. At this time, the contact guide plate 14 can move into the support cavity 18 through the blocking of the limit plate 27 until the plug 16 is pulled out from the inside of the socket 15, so that the jet device 6 and the grinding device 7 are powered off to prevent energy waste. Afterwards, when the support fence 28 moves to the cutting device 45 for vertical alignment, the cutting device 45 can be started to cut the optical lens 3 on the support fence 28;

[0046] Afterwards, the cut finished lenses will fall onto the guide plate 20. The top two sides of the guide plate 20 are inclined at 45 degrees, so that the lenses can be prevented from accumulating inside the guide plate 20. Afterwards, when the positioning substrate 19 continues to move toward the rear end, the disc 31 can be driven to contact the blocking plate 44. Through the blocking of the blocking plate 44, the disc 31 can drive the second piston rod 33 to slide toward the inside of the U-shaped cylinder 34, so that the first piston rod 30 can drive the movable rod 29 and the extrusion block 24 to move toward the rear end. When the extrusion block 24 contacts the front end of the support fence 28, the support fence 28 can be squeezed to separate, thereby expanding the gap between the support fences 28, so that the scraps of the optical lens 3 can fall onto the receiving cavity 43, completing the waste discharge work;

[0047] Afterwards, when the positioning base plate 19 moves toward the front end again, the disc 31 can be driven to disengage from the blocking plate 44, and the elasticity of the fourth spring 32 can drive the second piston rod 33 to reset to the rear end, causing the first piston rod 30 to move toward the front end, so that the extrusion block 24 can be pulled out from between the two support railings 28. At this time, the elasticity of the third spring 21 can drive the support railings 28 to move toward each other again until the support railings 28 fit together and the work is completed.

[0048] Example 2

[0049] On the basis of Example 1, Fig.10 As shown, the positioning base 49 includes a slide rod 50, a transfer cavity 51, an extension bottom plate 52, a suction cup 53 and a rotating shaft 54. The extension bottom plate 52 is fixedly mounted on the rear of both sides of the positioning base 49, the rotating shaft 54 ​​is rotatably mounted on the top of the extension bottom plate 52, the transfer cavity 51 is fixedly mounted on the outer ring of the rotating shaft 54, the slide rod 50 is slidably inserted on both sides of the transfer cavity 51 close to the positioning base 49, and the suction cup 53 is fixedly mounted on one end of the slide rod 50.

[0050] When implementing this embodiment, the transfer cavity 51 can be aligned with the positioning base 49 when it is vertically aligned with the cutting device 45, so that when the guide plate 20 discharges the lens, the lens can directly slide into the interior of the transfer cavity 51 to complete the lens reception work. Afterwards, when a certain amount of lenses are received inside the transfer cavity 51, the slide bar 50 can be pulled to the end away from the positioning base 49 until the suction cup 53 is out of contact with the positioning base 49, so that the transfer cavity 51 can be released. Afterwards, the rotating shaft 54 ​​can be rotated to drive the transfer cavity 51 loaded with the optical lens 3 to rotate, and then the empty transfer cavity 51 is rotated to be close to the positioning base 49, and then the slide bar 50 is moved until the suction cup 53 is adsorbed and fits with the outer surface of the positioning base 49, so that the transfer cavity 51 can be restricted and fixed, so that the transfer cavity 51 can receive the optical lens 3 and complete the work.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
