Description

Technical Field

[0001] The present invention relates to the technical field of optical lens processing, and in particular to cutting equipment and a method of using the same for optical lens processing. Background Art

[0002] Optical lenses are made of optical glass. Generally, optical lens processing requires cutting, grinding, polishing and other processes. When cutting optical lenses, lens cutting devices are needed. Existing cutting devices cannot push out the cut optical lens blanks, which is inconvenient for staff to take. The existing patent announcement number CN114851288B discloses a resin lens cutting device. Through the main board, sub-board, fixed frame, first gear, second gear, transmission belt and storage board, it realizes the function that after the lens plate moves to a certain position, the clean water in the water storage box will be evenly spread on the lens plate from both ends to complete the cooling work. This solves the problem that when the traditional resin lens cutting equipment is working, the friction between the cutter and the lens will generate a lot of heat, which will cause the edge of the resin lens to melt and turn yellow.

[0003] However, the staff is required to load the materials after each processing, and the staff loading and taking materials are inefficient. In addition, when the equipment is cutting, the coolant can only dissipate heat from one side of the lens during the cutting process of the tube knife, and the heat dissipation is very uneven, which is not conducive to ensuring the cutting quality.

[0004] Based on this, a cutting device and a method for using the optical lens processing are now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention

[0043] A protective sleeve 301 is provided above the loading turntable 200 where the cutting knife group 300 is located. The protective sleeve 301 is connected to the lower end of the mounting bracket 101 through a suspension rod. The diameter of the protective sleeve 301 is larger than the diameter of the cutting knife group 300, so that the cutting position can be protected;

[0044] The cutting drive unit includes a cutting sleeve 415 arranged at the upper end of the cutting cylinder 302, a cutting shaft rod 418 is slidably provided at the upper end of the cutting sleeve 415, a rotation limiter is provided between the cutting shaft rod 418 and the cutting sleeve 415, a first pulley 419 is provided on the outer side of the upper end of the cutting shaft rod 418, the cutting shaft rod 418 is connected to the cutting motor 406 for driving its rotation, the upper end of the first pulley 419 is rotatably connected to the mounting bracket 101, a reciprocating column 403 is provided on one side of the cutting sleeve 415, and the reciprocating column The driving shaft at the upper end of 403 is rotatably connected to the mounting bracket 101, and the second pulley 421 on the mounting bracket 101 is connected to the first pulley 419 through a synchronous belt 420. A guide slip ring 430 is provided on the outer side of the reciprocating column 403 for sliding. The guide slip ring 430 is connected to the cutting sleeve 415 through a connecting cross bar 429. The end of the connecting cross bar 429 is provided with a collar 432 rotatably connected to the cutting sleeve 415. The setting of the collar 432 prevents the connecting cross bar 429 from interfering with the rotation of the cutting sleeve 415. A guide member is provided between 429 and the mounting bracket 101, a guide pin 431 is provided on the inner side of the guide slip ring 430, and a reciprocating guide groove 404 matching the guide pin 431 is provided on the outer side of the reciprocating column 403. When the cutting shaft 418 rotates, the first pulley 419 drives the second pulley 421 to rotate through the synchronous belt 420, thereby driving the reciprocating column 403 to rotate, and the reciprocating guide groove 404 on the outer side of the reciprocating column 403 matches the guide pin 431 to drive the guide slip ring 430 to move up and down. When the guide slip ring 430 moves up and down, When the cutting sleeve 415 is driven to move up and down along the cutting shaft 418 through the connecting cross bar 429, the cutting knife group 300 at the lower end of the cutting shaft 418 will reciprocate up and down to complete the cutting feed and retract actions. The outer side of the guide slip ring 430 is also provided with a switching transmission member for driving the loading turntable 200 to rotate intermittently to achieve material replacement. When the cutting knife group 300 moves upward, the switching transmission member can drive the loading turntable 200 to rotate a predetermined angle, thereby transferring the next workpiece A to the bottom of the cutting knife group 300 to complete automatic loading;

[0045] The switching transmission member includes a central worm wheel 401 arranged on the central rotating shaft 102, a worm 402 is meshed on the outer side of the central worm wheel 401, the end of the worm 402 is connected to a one-way transmission gear 426 through a linkage shaft 424, a bearing ring 425 is provided for rotation on the outer side of the linkage shaft 424, the bearing ring 425 is connected to the mounting bracket 101 through a positioning vertical rod, the one-way transmission gear 426 is connected to the linkage shaft 424 through a ratchet or an overrunning clutch, a vertically arranged transmission rack 422 is meshed on the outer side of the one-way transmission gear 426, and the upper end of the transmission rack 422 is connected to a guide slip ring through a cross bar. 430 is connected. When the guide slip ring 430 drives the transmission rack 422 to move downward, the transmission rack 422 moves downward to drive the one-way transmission gear 426 to rotate. Since the one-way transmission gear 426 and the linkage shaft 424 are one-way transmission, the transmission rack 422 will not drive the linkage shaft 424 to rotate when it moves downward. However, when the transmission rack 422 moves upward, the transmission rack 422 will match the one-way transmission gear 426 to drive the linkage shaft 424 to rotate, thereby providing power for the rotation of the worm 402. The worm 402 matches the central worm wheel 401, thereby providing power for the intermittent rotation of the loading turntable 200.

[0046] The guide member includes a vertical guide sleeve 428 disposed outside the connecting crossbar 429, and the vertical guide sleeve 428 is slidably sleeved on the vertical guide rod 427, and the upper end of the vertical guide rod 427 is connected to the mounting bracket 101, so that the reciprocating column 403 can slide up and down more smoothly;

[0047] The rotation limiting member includes a rotation limiting groove 416 arranged on the inner wall of the cutting sleeve 415, and a rotation limiting protrusion 417 matching the rotation limiting groove 416 is arranged on the outer side of the cutting shaft 418. The rotation limiting protrusion 417 cooperates with the rotation limiting groove 416 to only allow axial sliding but not rotation.

[0048] The water spray assembly includes a rotating ring box 304 rotatably arranged on the outer side of the upper end of the cutting cylinder 302, and a plurality of water inlets are distributed on the surface of the cutting cylinder 302 where the rotating ring box 304 is located, and a cooling nozzle 306 is provided at each water inlet position, and the lower port of the cooling nozzle 306 extends toward the position of the cutting tooth 307, and the upper end of the rotating ring box 304 is connected to a water inlet pipe 303, and the upper end of the water inlet pipe 303 is connected to the sliding inner tube 410, and the sliding sleeve 409 is provided on the upper end of the sliding inner tube 410, and the upper end of the sliding sleeve 409 is connected to the output end of the liquid pump 408, and the liquid pump 408 is installed at the lower end of the mounting bracket 101, and the liquid inlet end of the liquid pump 408 is connected to the liquid supply tank 407 at the upper end of the mounting bracket 101, and the liquid pump 408 sends the coolant in the liquid supply tank 407 into the rotating ring box 304, and the liquid is then sprayed toward the cutting tooth 307 along the cooling nozzle 306, thereby completing uniform cooling;

[0049] It should be noted that the water inlet pipe 303, the sliding inner pipe 410 and the sliding pipe sleeve 409 are hard pipes, and the sliding inner pipe 410 and the sliding pipe sleeve 409 are slidingly connected. Therefore, when the cutting cylinder 302 rotates rapidly, the rotating ring box 304 rotates relative to the outer side of the cutting cylinder 302 to supply water, thereby avoiding the problem of entanglement between the water inlet pipe 303, the sliding inner pipe 410 and the sliding pipe sleeve 409.

[0050] Fig.10 As shown, an auxiliary positioning rod 433 may be provided at the upper end of the swivel box 304, and an auxiliary positioning sleeve 434 may be slidably provided at the upper end of the auxiliary positioning rod 433, and the auxiliary positioning sleeve 434 may be connected to the mounting bracket 101, thereby avoiding the problem of excessive force on the sliding inner tube 410 and the sliding tube sleeve 409;

[0051] The collecting unit includes a recycling box 413, the upper end of which is provided with a receiving inclined plate 411 for guiding the blanks, the receiving inclined plate 411 is provided with filter holes 414 for filtering, and the end of the receiving inclined plate 411 is provided with a buffer groove 412 for buffering the blanks. After cutting, the blanks will fall onto the receiving inclined plate 411, and then slide into the buffer groove 412 along the receiving inclined plate 411 to complete the collection of the blanks. The feed port of the liquid supply box 407 is connected to the reflux pump inside the recycling box 413 through a pipeline to realize the recycling of the coolant.

[0052] The feeding unit 500 includes a vertically arranged buffer cylinder, the lower end of which corresponds to the position of the discharge hole 201 at the upper end of the loading turntable 200, and the outer side of the buffer cylinder is connected to the mounting bracket 101 through a positioning rod. When the loading turntable 200 rotates, the discharge hole 201 is transferred to the buffer cylinder position, and the workpieces at the bottom of the buffer cylinder are filled into the discharge hole 201, completing automatic loading;

[0053] The support unit includes a first movable support plate 105 and a second movable support plate 107 symmetrically arranged on both sides of the lower end of the discharge hole 201, the first movable support plate 105 and the second movable support plate 107 are slidably arranged with the bottom of the loading turntable 200, the outer ends of the first movable support plate 105 and the second movable support plate 107 are provided with two horizontal sliding holes, the outer ends of the unloading guide rods 110 in the horizontal sliding holes are connected to the positioning side blocks 108 at the bottom of the loading turntable 200, the positioning side blocks 108 and the second movable support plate 107 or the first movable support plate 105 are connected by unloading springs 109, the relative positions of the second movable support plate 107 and the first movable support plate 105 constitute a unloading gap 106 for supporting the workpiece A, the outer sides of the second movable support plate 107 and the first movable support plate 105 are provided with an unloading lever 111, and the lower end of each unloading lever 111 is provided with a unloading guide wheel 112, and the diameter of the unloading gap 106 is smaller than the diameter of the cut lens;

[0054] The unloading unit includes a waste collecting barrel 103 for receiving materials, the material receiving end of the waste collecting barrel 103 corresponds to the position of the discharge hole 201, the waste collecting barrel 103 is connected to the base 100 through a connecting frame, and an auxiliary unloading triangular plate 104 for separating the two unloading guide wheels 112 is provided at the upper port position of the waste collecting barrel 103, the lower end of the auxiliary unloading triangular plate 104 is connected to the upper end of the avoidance guide rod 114, the avoidance guide rod 114 is slidably arranged on the avoidance sliding sleeve 113, and the avoidance sliding sleeve 113 is connected and fixed to the outer side of the waste collecting barrel 103, and an avoidance spring 115 is provided between the auxiliary unloading triangular plate 104 and the avoidance sliding sleeve 113. As the loading turntable 200 rotates, the two unloading guide wheels 112 are separated. When the wheel 112 is transferred to the position of the auxiliary unloading triangle plate 104, when the vertex of the auxiliary unloading triangle plate 104 interferes with the path of the unloading guide wheel 112, the auxiliary unloading triangle plate 104 will move down along the avoidance guide rod 114 to avoid interference problems. As the loading turntable 200 rotates, when the two unloading guide wheels 112 are transferred to the position of the auxiliary unloading triangle plate 104, under the action of the inclined surface of the auxiliary unloading triangle plate 104, the two unloading guide wheels 112 will slide along the inclined surface of the auxiliary unloading triangle plate 104, thereby separating the second movable support plate 107 and the first movable support plate 105 through the unloading lever 111, so that the waste in the discharge hole 201 will lose its supporting force, and the waste will enter the waste collecting barrel 103 to complete the collection.

[0055] Working principle: In actual use, multiple workpieces A are placed in the feeding unit 500, and the cutting drive unit drives the cutting knife group 300 to rotate, and the cutting motor 406 drives the cutting shaft 418 to rotate. When the cutting shaft 418 rotates, the first pulley 419 drives the second pulley 421 to rotate through the synchronous belt 420, thereby driving the reciprocating column 403 to rotate, and the reciprocating guide groove 404 on the outer side of the reciprocating column 403 matches the guide pin 431 to drive the guide slip ring 430 to move up and down. When the guide slip ring 430 moves up and down, it will drive the cutting sleeve 415 to move up and down along the cutting shaft 418 through the connecting cross bar 429, so that the cutting knife group 300 at the lower end of the cutting shaft 418 will reciprocate up and down to complete the cutting feed and retract actions. When the cutting knife group 300 moves downward, it will cut the workpiece A in the discharge hole 201;

[0056] During cutting, the liquid pump 408 delivers the coolant in the liquid supply tank 407 into the rotating ring box 304, and then the liquid is sprayed toward the cutting teeth 307 along the cooling nozzle 306, so as to achieve uniform cooling. When the workpiece A is cut, under the action of the downward pressure spring 310, the downward pressure rod 309 drives the downward pressure positioning block 308 to squeeze downward, so as to push away the cut blank, and the pushed blank will fall to the collection unit, and the waste liquid will also be filtered and collected, so as to achieve the recycling of resources.

[0057] When the guide slip ring 430 drives the transmission rack 422 to move downward, the transmission rack 422 moves downward to drive the one-way transmission gear 426 to rotate. Since the one-way transmission gear 426 and the linkage shaft 424 are one-way transmission, the transmission rack 422 will not drive the linkage shaft 424 to rotate when it moves downward. However, when the transmission rack 422 moves upward, the transmission rack 422 will match the one-way transmission gear 426 to drive the linkage shaft 424 to rotate, thereby providing power for the rotation of the worm 402. The worm 402 matches the central worm gear 401, thereby providing power for the intermittent rotation of the loading turntable 200. In this way, cutting and feeding are matched, which greatly improves the processing efficiency.

[0058] It should be noted that when the cutting knife group 300 moves downward for cutting, the workpiece A will not rotate with the loading turntable 200. When the cutting knife group 300 starts to return to the city, the transmission gear 426 is still below the transmission rack 422, and the transmission will not be completed at this time. When the cutting knife group 300 completely leaves the loading turntable 200, the transmission gear 426 and the transmission rack 422 are transmitted, and the loading turntable 200 starts to switch positions to replace the next workpiece A.

[0059] When the cut waste is transferred to the unloading position, as the loading turntable 200 rotates, the two unloading guide wheels 112 are transferred to the position of the auxiliary unloading triangle plate 104. Under the action of the inclined surface of the auxiliary unloading triangle plate 104, the two unloading guide wheels 112 will slide along the inclined surface of the auxiliary unloading triangle plate 104, thereby separating the second movable support plate 107 and the first movable support plate 105 through the unloading lever 111, so that the waste in the discharge hole 201 will lose the supporting force, and the waste will enter the waste collecting barrel 103 to complete the collection.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
