Description

Technical Field

[0001] This invention relates to the field of optical lens processing technology, specifically to an optical lens laser cutting processing device. Background Technology

[0002] Optical lens cutting is a high-precision manufacturing process widely used in the forming and segmentation of optical components. Optical lens blanks are mainly divided into plane mirror blanks and curved mirror blanks. Plane mirror blanks are widely used in objective lenses of optical instruments and observation lenses of industrial inspection equipment, which can realize the straight transmission or parallel reflection of light. Curved mirror blanks, on the other hand, have functions such as focusing, scattering, or imaging, and are often used in the fields of telescope reflectors and car rearview mirrors.

[0003] Currently, laser cutting equipment is commonly used to cut optical lens blanks. The operator fixes the optical lens blank on the worktable of the device, then adjusts the position of the support platform of the worktable so that the area to be cut on the blank is precisely aligned with the laser output end of the laser cutting machine. The laser cutting machine is then started, and the blank is laser-cut according to the preset cutting trajectory to form the outline of the finished optical lens that meets the size requirements. After cutting, the operator needs to manually separate the cut finished optical lens from the surrounding waste material to complete the cutting and processing of the optical lens blank.

[0004] The existing technology has the following problems when laser cutting optical lens blanks: the separation of waste material and finished product after cutting depends on manual operation, which greatly reduces the overall processing efficiency. It is also easy for the finished product to be scratched or damaged due to improper operation by the operator, which will damage the optical performance and appearance quality of the optical lens. In addition, the existing fixtures have poor adaptability to optical lens blanks with different shapes, such as curved mirrors and plane mirrors. The same set of fixtures cannot be adapted to the processing of two types of blanks at the same time, and special fixtures often need to be replaced, which leads to a decrease in the cutting efficiency of optical lens blanks.

[0015] The beneficial effects of this invention are as follows: First, this invention can support and fix each cutting area of ​​the optical lens blank when clamping and fixing it, so that after the optical lens blank is processed, the finished optical lens and waste can be quickly separated, ensuring overall processing efficiency. At the same time, it prevents scratches and other damage to the finished product caused by improper operation by the operator, ensuring the optical performance and appearance quality of the optical lens.

Detailed Implementation

[0032] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0033] See Figure 1 , Figure 2 and Figure 3 An optical lens laser cutting processing device includes a worktable 1, a laser cutting machine 2 mounted on the upper right side of the worktable 1, a support platform 11 that moves left and right, two clamping units 3 symmetrically arranged front and back mounted on the upper end of the support platform 11, and a stabilizing unit 4 mounted in the middle of the upper end of the support platform 11. The clamping units 3 are used to clamp and fix the ends of the optical lens blank. The support platform 11 can drive the optical lens blank to move left and right, and the laser cutting head of the laser cutting machine 2 can perform laser cutting on the optical lens in the front and back direction. In addition, the laser cutting head can be controlled by CNC to perform precise laser cutting on the blank according to a preset cutting trajectory.

[0034] It should be noted that the CNC control of the laser cutting machine 2 and the carrier platform 11 is existing technology, and will not be elaborated on here.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The stabilizing unit 4 includes multiple adjusting groups 41 evenly arranged front and back on the support platform 11. Multiple mounting plates 43 evenly arranged left and right are mounted on the adjusting groups 41 via suction groups 42. Multiple circumferentially evenly arranged support cylinders 44 are mounted on the mounting plates 43. Suction cups 45 are fixedly mounted on the upper ends of the support cylinders 44. The support cylinders 44 are connected to the suction groups 42. A sealing plate 442 is slidably mounted inside the support cylinder 44 via a return spring 441. A sealing ring 46 is slidably sleeved on the outer side of the support cylinder 44. A transmission plate 112 is mounted on the upper right side of the support platform 11 via an electric push rod 111. Multiple suction groups... A lower pressure plate 47 is installed together between groups 42, and the right end of the lower pressure plate 47 is attached to the lower side of the transmission plate 112. The stabilizing unit 4 can support and fix each cutting area of ​​the optical lens blank. After the optical lens blank is processed, the finished optical lens can be fixed on the stabilizing unit 4, while the optical lens waste can fall off, thereby quickly separating the finished optical lens and the waste, thus ensuring overall processing efficiency and ensuring the optical performance and appearance quality of the optical lens. In addition, the stabilizing unit 4 can support and fix each cutting area of ​​optical lens blanks of different shapes, thereby increasing the applicability of the present invention.

[0036] Specifically, when optical lenses need to be cut, the operator first adjusts the position of the mounting plate 43 through the adjustment group 41 so that the position of the mounting plate 43 corresponds one-to-one with the cutting area of ​​the optical lens blank. Then, the optical lens blank is placed on the suction cup 45 and the end of the optical lens blank is clamped and fixed by the clamping unit 3. During the clamping process, the clamping unit 3 can press down on the optical lens blank, so that the multiple suction cups 45 corresponding to the mounting plate 43 are adsorbed at the lower end of the optical lens blank cutting area corresponding to the mounting plate 43. Then, the electric push rod 111 is controlled to drive the transmission plate 112 to move downward. The transmission plate 112 drives the lower pressure plate 47 to move downward. The lower pressure plate 47 drives the sealing plate 442 to move downward through the air extraction group 42 and compresses the return spring 441. As the sealing plate 442 moves downward, the adsorption force of the suction cup 45 on the optical lens blank gradually increases, so that the suction cup 45 is stably adsorbed at the lower end of the optical lens blank.

[0037] Finally, the support platform 11 and the laser cutting machine 2 are started, so that the laser cutting machine 2 can perform laser cutting on the optical lens blank. After the laser cutting of the optical lens blank is completed, the finished optical lens is still fixed on the corresponding suction cup 45, while the optical lens waste falls onto the support platform 11 under the action of gravity, and the finished optical lens is taken out from the suction cup 45 by the operator.

[0038] To ensure that the suction cup 45 can adhere to the lower end of the optical lens blank, the present invention adopts the following structure: (See attached diagram) Figure 1 , Figure 2 and Figure 4The clamping unit 3 includes a back plate 31 fixedly installed on the support platform 11. A support roller 32 is fixedly installed at one end of the back plate 31 near the middle of the support platform 11, and a sliding plate 33 is slidably installed on it. The sliding plate 33 is located above the support roller 32. An adjusting screw 34 is connected between the sliding plate 33 and the back plate 31. A clamping roller 35 is installed at one end of the sliding plate 33 near the middle of the support platform 11. Both the clamping roller 35 and the support roller 32 are made of rubber to prevent the clamping force of the clamping roller 35 and the support roller 32 from being too large and causing damage to the optical lens blank.

[0039] Specifically, after the optical lens blank is placed on the suction cup 45, the two adjusting screws 34 are rotated synchronously to drive the two sliding plates 33 to move downwards synchronously. The sliding plates 33 drive the clamping rollers 35 to move downwards, so that the clamping rollers 35 press on the upper end of the optical lens blank and drive the optical lens blank to move downwards, so that the suction cup 45 is adsorbed on the lower end of the optical lens blank. Finally, the clamping rollers 35 and the support rollers 32 cooperate to clamp and fix the end of the optical lens blank.

[0040] To ensure that the suction cup 45 can adhere to the lower end of the corresponding optical lens blank cutting area, the invention adopts the following structure: (See reference) Figure 1 and Figure 5 The adjustment assembly 41 includes an adjustment plate 411. The adjustment plate 411 located in the middle is fixedly connected to the support platform 11. The adjustment plates 411 located on the front and rear sides are slidably connected to the support platform 11 through a first synchronous screw 412. Multiple adjustment seats 413 evenly arranged on the left and right sides are installed on the upper end of the adjustment plate 411. The adjustment seat 413 located in the middle is fixedly connected to the adjustment plate 411. The two adjustment seats 413 located on the left and right sides are slidably connected to the adjustment plate 411 through a second synchronous screw 414. The sliding connection between the adjustment plate 411 and the support platform 11, as well as the sliding connection between the adjustment seats 413 and the support platform 11, are also included. The sliding connection of the adjusting plate 411 is equipped with a bellows cover, which facilitates the quick cleaning of optical lens waste. By rotating the first synchronous screw 412, the front and rear positions of the adjusting plates 411 located on the front and rear sides are adjusted synchronously. By rotating the second synchronous screw 414, the left and right positions of the two adjusting seats 413 located on the left and right sides are adjusted synchronously. This allows the position of the mounting plate 43 to be adjusted so that the mounting plate 43 corresponds one-to-one with the optical lens blank cutting area. This allows the multiple suction cups 45 corresponding to the mounting plate 43 to be adsorbed at the lower end of the optical lens blank cutting area corresponding to the mounting plate 43.

[0041] See Figure 2 , Figure 6 , Figure 10 and Figure 11The air extraction assembly 42 includes an air extraction cylinder 422 fixedly installed on the adjusting seat 413 via an L-shaped connecting plate 421. The upper end of the air extraction cylinder 422 is fixedly connected to the mounting plate 43. A corrugated pipe 423 is connected between the upper end of the outer side of the air extraction cylinder 422 and the lower end of the corresponding support cylinder 44. A piston plate 425 is slidably installed inside the air extraction cylinder 422. An air extraction rod 426 is fixedly installed at the lower end of the piston plate 425. The lower end of the air extraction rod 426 slides through the air extraction cylinder 422. A telescopic rod 424 is installed at the lower end of two adjacent air extraction rods 426. The end of the telescopic rod 424 is set as a telescopic structure. Multiple telescopic rods 424 arranged on the left and right are connected to the corresponding lower pressure plate 47. The telescopic rod 424 located in the middle is fixedly connected to the lower pressure plate 47. The telescopic rods 424 located on the left and right sides are slidably connected to the lower pressure plate 47, so as not to interfere with the position adjustment of the mounting plate 43.

[0042] After the clamping roller 35 and the support roller 32 clamp and fix the optical lens blank, the control electric push rod 111 drives the transmission plate 112 to move downward. The transmission plate 112 drives the multiple telescopic rods 424 arranged on the left and right to move downward through the lower pressure plate 47. The telescopic rods 424 drive the piston plate 425 to move downward through their corresponding two suction rods 426. Since the space between the suction cylinder 422, the piston plate 425, the bellows 423, the support cylinder 44 and the sealing plate 442 is a closed space, when the piston plate 425 moves downward, the sealing plate 442 moves downward under the action of air pressure.

[0043] To facilitate the rapid removal of the cut optical lens product and further increase the cutting efficiency of the optical lens blank, this invention adopts the following structure: (See attached diagram) Figure 4 , Figure 6 , Figure 8 , Figure 9 and Figure 11 A synchronous plate 462 is fixedly installed between two adjacent sealing rings 46 corresponding to the same mounting plate 43. A top extension spring connects the synchronous plate 462 and the mounting plate 43. A square plate 463 is fixedly installed at the center of the front end of the synchronous plate 462. A mating plate 464 is installed at the front end of multiple square plates 463 arranged on the left and right. The square plate 463 in the middle and the mating plate 464 are fixedly connected. The square plates 463 on the left and right sides and the mating plate 464 are slidably connected to each other to prevent the mating plate 464 from drying out. The position adjustment of the mounting plate 43 is involved; multiple lifting plates 114 are evenly arranged front and back on the upper end of the transmission plate 112 through the elastic relief rod 113. The height of the lifting plates 114 decreases from front to back. The installation positions of multiple mating plates 464 arranged front and back correspond to the lifting plates 114. The right end of the mating plate 464 is located above the lifting plate 114. Multiple pressure relief holes 443 are evenly arranged circumferentially on the outside of the support cylinder 44. A through hole 461 is opened on the outside of the sealing ring 46 and below the pressure relief holes 443.

[0044] After the laser cutting of the optical lens blank is completed, the electric push rod 111 drives the transmission plate 112 to move upward. The transmission plate 112 drives the lifting plate 114 to move upward through the elastic relief rod 113. When the lifting plate 114 moves to the corresponding position of the mating plate 464 and continues to move upward, the lifting plate 114 drives the multiple square plates 463 arranged on the left and right to move upward through the mating plate 464. Under the action of multiple synchronous plates 462, the square plates 463 drive the multiple sealing rings 46 to move upward through the synchronous plates 462. When the sealing rings 46 move upward a certain distance, the through hole 461 and the pressure relief hole 443 are connected. At this time, air can enter the suction cup 45 through the through hole 461 and the pressure relief hole 443, thereby quickly releasing the suction cup 45 from fixing the finished optical lens. The suction cups 45 on the multiple mounting plates 43 arranged on the left and right sides are simultaneously released from fixing the finished optical lenses. Since the height of the lifting plate 114 decreases from front to back, the suction cups 45 on the corresponding mounting plates 43 are unlocked from front to back, making it easier for the operator to remove the finished optical lenses one by one. As the transmission plate 112 moves upward, it gradually separates from the lower pressure plate 47, allowing the sealing plate 442 to return to its initial position under the action of the return spring 441. It should be noted that the upward movement distance of the sealing ring 46 driven by the electric push rod 111 through the transmission plate 112 is achieved by precise control of the electric push rod 111 after precise calculation by those skilled in the art. The specific control method is existing technology and will not be repeated.

[0045] To increase the stability of the suction cup 45 when supporting and fixing optical lens blanks of different shapes, the present invention adopts the following structure: (See attached diagram) Figure 2 , Figure 3 , Figure 6 and Figure 7 Multiple synchronous plates 462 corresponding to the same mounting plate 43 are all fixedly mounted with circular plates 465 on opposite sides through connecting plates. The outer side of the circular plate 465 is hinged with an elastic locking rod 466 corresponding to the support cylinder 44 through a diagonal rod, and the fixed section of the elastic locking rod 466 is radially slidably connected to the mounting plate 43. The telescopic section of the elastic locking rod 466 has an inclined surface. The support cylinder 44 is slidably connected to the mounting plate 43 through a top extension spring 48. Multiple locking holes are evenly arranged vertically on the outer side of the support cylinder 44 at positions corresponding to the elastic locking rod 466. The locking holes can cooperate with the telescopic section of the elastic locking rod 466 to lock the position of the support cylinder 44.

[0046] Specifically, when the curved or flat lens blank is placed on the suction cup 45 and pressed down, under the action of the second extension spring 48, the support cylinder 44 can drive the suction cup 45 to adhere to the lower end of the curved or flat lens blank. When the optical lens blank moves downward through the suction cup 45, the inclined surfaces of the support cylinder 44 and the elastic locking rod 466 cooperate to compress the telescopic section of the elastic locking rod 466, thus not interfering with the downward movement of the support cylinder 44. After the optical lens blank is clamped and fixed, the telescopic section of the elastic locking rod 466 is inserted into the corresponding locking hole, preventing the support cylinder 44 from moving upward. When the synchronous plate 462 moves upward, the synchronous plate 462 drives the circular plate 465 to move upward through the connecting plate. The circular plate 465 drives multiple elastic locking rods 466 to move inward synchronously through the inclined rod, causing the telescopic section of the elastic locking rod 466 to move out of the corresponding locking hole, thereby allowing the support cylinder 44 to return to its initial position under the action of the second extension spring 48.

[0047] It should be noted that, for reference Figure 3 The curvature of the curved mirror blank is usually small. Therefore, when the suction cup 45 is attached to the lower end of the curved mirror blank, the deformation of the multiple extension springs 48 corresponding to the same cutting area of ​​the curved mirror blank is small. This ensures that the suction force of the multiple suction cups 45 on the curved mirror blank corresponding to the same cutting area will not differ too much, thus enabling the suction cup 45 to stably support the curved mirror blank.

[0048] It should be noted that existing technologies can also employ simple fixed support methods, such as setting several suction cups 45 on the support platform 11, and supporting and fixing each cut area of ​​the optical lens blank after manual adjustment of their positions. Although it is technically easier and has a lower initial cost to achieve basic fixation using only suction cups 45, it only superficially addresses the single problem of "low efficiency of manual separation of finished optical lenses and waste materials." It only achieves quick and simple fixation through the adsorption force of the suction cups 45. In this existing technology, it is impossible to completely ensure that the suction cups 45 stably adsorb each cut area of ​​the optical lens blank. For curved mirrors, the suction cups 45 corresponding to different cut areas will vary. The suction force may vary, causing the cut optical lens to fall off the suction cup 45 and become damaged. However, in this invention, multiple distributed suction cups 45 fix the cutting area of ​​the optical lens blank. The suction group 42, controlled by the electric push rod 111, increases the suction force of the suction cups 45 on the optical lens blank, achieving stable suction of the optical lens blank. Furthermore, after cutting, the invention can automatically depressurize and synchronously unlock. The lifting plate 114, mating plate 464, and synchronization plate 462 allow for sequential release of suction from front to back, enabling operators to remove the lenses in an orderly and efficient manner without manual separation, greatly improving the efficiency of finished product removal. Simultaneously, the support cylinder 44, through the extension spring 48 and elastic locking rod 466, can achieve adaptive height adjustment and locking, adapting to lens blanks with different curvatures or thicknesses, significantly improving the versatility and practicality of the device. Although this invention adds structures such as the adjustment group 41, the air extraction group 42, and the electric push rod 111 compared to the simple fixing method, these are all conventional mechanical and pneumatic components, with controllable cost, high reliability, and long-term use after a single assembly and adjustment. Especially in the scenario of high-volume, multi-variety optical lens cutting, the improved processing efficiency, yield, and operational consistency brought about by this invention result in economic benefits far exceeding the initial investment, demonstrating significant practicality and necessity.
