Description

Technical Field

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

[0002] An optical lens is an optical element made of a transparent material with a spherical surface. It is a glass or plastic component used in lighting fixtures to change the direction of light or control light distribution. An optical lens consists of a hemisphere and rings distributed along the edge of the hemisphere's base, and is generally manufactured using extrusion molding. To allow multiple optical lenses to be molded in a single step, a connecting frame is used after molding. Before further processing, the optical lens needs to be cut from the connecting frame, and any burrs need to be removed.

[0003] Currently, optical lenses are typically cut using laser cutting equipment. Each time a cut is performed, the operator needs to manually place the optical lens into the designated cutting station, resulting in low overall efficiency of the cutting operation. Summary of the Invention

[0004] The purpose of this invention is to provide an optical lens laser cutting device that can automatically remove the optical lens from the conveying mechanism and place it on the cutting station before each cut, ensuring continuous cutting without manual operation by the operator and improving the efficiency of the cutting operation.

[0005] The embodiments of the present invention are achieved through the following technical solution: an optical lens laser cutting device, including a worktable, a cutting seat disposed on the worktable, a cutting head disposed on the cutting seat, and a conveyor for conveying the workpiece toward the cutting seat. The worktable is provided with a suction mechanism for picking up optical lenses, a flipping mechanism for driving the suction mechanism to flip, a lifting mechanism for driving the flipping mechanism to move vertically, and a transverse mechanism for driving the lifting mechanism to move along the length direction of the worktable.

The rotating rod is rotatably connected inside the support base, and the end of the rotating rod extends outside the support base. The worm wheel is coaxially mounted on the rotating rod. Two support blocks are provided on the support base. The worm gear is rotatably mounted between the two support blocks and meshes with the worm wheel. The rotating motor is fixedly mounted on one of the support blocks, and the output shaft of the rotating motor is coaxially connected to the worm gear.

[0008] Furthermore, there are two sets of lifting mechanisms. Each side of the worktable has a sliding groove along its own length.

A drive rod is provided on the piston rod of the transverse electric cylinder. A moving groove communicating with the slide is provided on the worktable. The drive rod passes through the moving groove and is fixedly connected to the slider.

[0010] Furthermore, a waste collection box is provided on the workbench and directly below the cutting head, and a finished product collection box for collecting finished products is provided on one side of the workbench. A material guiding mechanism for guiding finished products into the finished product collection box is also provided on the workbench. The material guiding mechanism is inclined and the end of the material guiding groove near the cutting head is higher than the end of the material guiding groove near the finished product collection box.

[0011] Furthermore, the material guiding mechanism includes a material guiding trough and support frames disposed on both sides of the material guiding trough. The material guiding trough is slidably disposed between the two support frames. One of the support frames is provided with a moving component for driving the material guiding trough to move closer to or away from the cutting head.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] Example 1

[0029] The following description, in conjunction with specific embodiments, provides further details. Figures 1-6As shown, this invention is an optical lens laser cutting device, including a worktable 1, a cutting seat 11 mounted on the worktable 1, a cutting head 12 slidably mounted on the cutting seat 11, and a conveyor 2 for conveying workpieces toward the cutting seat 11. The worktable 1 is provided with a suction mechanism 3 for picking up optical lenses, a flipping mechanism 4 for driving the suction mechanism 3 to flip, a lifting mechanism 5 for driving the flipping mechanism 4 to move vertically, and a transverse mechanism 6 for driving the lifting mechanism 5 to move along the length of the worktable 1. The conveyor 2 periodically and intermittently conveys the optical lenses to be processed. When the conveyor 2 conveys a set of optical lenses to be processed to the end, the suction mechanism 3 flips 180° and the suction part faces downward. Then, the transverse mechanism 6 drives the suction mechanism 3 to move to directly above the optical lens located at the end of the conveyor 2. Then, the lifting mechanism 5 drives the suction mechanism 3 to move downward and activates the suction mechanism 3 to pick up the optical lens. After the optical lens is attracted, the lifting mechanism 5 drives the attraction mechanism 3 to move upward. The horizontal movement mechanism 6 drives the lifting mechanism 5 to move towards the gap between the cutting mechanism and the conveyor 2. The flipping mechanism 4 drives the attraction mechanism 3 to flip so that the optical lens is located on the top surface of the attraction mechanism 3. The horizontal movement mechanism 6 then drives the lifting mechanism 5 to continue moving to the designated cutting position. The lifting mechanism 5 is then adjusted to a suitable cutting height. The cutting head 12 is then started and begins cutting according to the preset program.

[0030] Reference Figure 1 , Figure 2 As shown, the suction mechanism 3 includes a mounting base 31, a suction pump 32, and multiple vacuum suction cups 33. A distribution pipe 34 is provided on the mounting base 31. The multiple vacuum suction cups 33 are distributed along the circumference of the distribution pipe 34 and connected to it via suction branch pipes 35. The suction pump 32 is located on the side of the mounting base 31 opposite to the vacuum suction cups 33 and is connected to the distribution pipe 34 via a main suction pipe 36. Activating the suction pump 32 draws the distribution pipe 34 to a negative pressure state. The distribution pipe 34, through multiple suction branch pipes 35, keeps all the vacuum suction cups 33 under negative pressure, thereby enabling the suction of the optical lens.

[0031] Reference Figure 2 , Figure 3As shown, the flipping mechanism 4 includes a rotating rod 41, which is fixedly mounted on one side of the mounting base 31. Support seats 42 are provided at both ends of the rotating rod 41, and rotating components 43 for driving the rotating rod 41 to rotate are provided on the support seats 42. The rotating component 43 includes a rotating motor 431, a worm gear 432, and a worm wheel 433. The rotating rod 41 is rotatably connected inside the support seat 42, and its end extends outside the support seat 42. The worm wheel 433 is coaxially mounted on the rotating rod 41. Two support blocks 434 are provided on the support seat 42. The worm gear 432 is rotatably mounted between the two support blocks 434 and meshes with the worm wheel 433. The rotating motor 431 is fixedly mounted on one of the support blocks 434, and its output shaft is coaxially connected to the worm gear 432. The starting motor 431 drives the worm gear 432 to rotate. Under the meshing action of the worm gear 432, the worm wheel 433 rotates and drives the rotating rod 41 to rotate. This causes the rotating rod 41 to drive the mounting base 31 to flip, thereby changing the direction of the suction surface on the vacuum suction cup 33. This makes it convenient to have the suction surface facing down when picking up optical lenses and to have the suction surface facing up when cutting.

[0032] Reference Figure 2 As shown, there are two sets of lifting mechanisms 5. Slide grooves 13 are provided on both sides of the worktable 1 along its length. The two sets of lifting mechanisms 5 are slidably disposed within the slide grooves 13 on both sides. Each lifting mechanism 5 includes a lifting cylinder 51. A slider 52 is fixedly mounted on the cylinder of the lifting cylinder 51, and the slider 52 is slidably connected within the slide groove 13. The piston rod of the lifting cylinder 51 is fixedly connected to the support base 42. The lifting cylinder 51 drives the support base 42 to move vertically, thus simultaneously causing the suction mechanism 3 to move vertically. The transverse movement mechanism 6 includes a transverse movement cylinder 61, which is fixedly disposed outside the worktable 1. A drive rod 62 is mounted on the piston rod of the transverse movement cylinder 61. A moving groove 14 communicating with the slide groove 13 is provided on the worktable 1. The drive rod 62 passes through the moving groove 14 and is fixedly connected to the slider 52. The horizontal electric cylinder 61 drives the slider 52 to move, which in turn drives the lifting mechanism 5, the flipping mechanism 4 and the suction mechanism 3 to move synchronously, so that the optical lens moves closer to or further away from the cutting head 12.

[0033] Reference Figure 1 , Figure 4As shown, a waste collection box 15 is provided on the workbench 1 and directly below the cutting head 12. The waste collection box 15 is used to collect waste chips generated during the cutting process and waste materials such as connecting frames generated during injection molding, so as to facilitate recycling. A finished product collection box 16 is provided on one side of the workbench 1 to collect finished products after cutting. The workbench 1 is also provided with a material guiding mechanism 7 for guiding finished products into the finished product collection box 16. The material guiding mechanism 7 is inclined and the end of the material guiding trough 71 near the cutting head 12 is higher than the end of the material guiding trough 71 near the finished product collection box 16.

[0034] Reference Figure 4 , Figure 5 As shown, the material guiding mechanism 7 includes a material guiding trough 71 and support frames 72 disposed on both sides of the material guiding trough 71. The material guiding trough 71 is slidably disposed between the two support frames 72. One of the support frames 72 is provided with a moving component 73 for driving the material guiding trough 71 to move closer to or away from the cutting head 12. The moving component 73 includes a moving motor 731, a driving gear 732, and a driven rack 733. The moving motor 731 is fixedly disposed on the support frame 72, the driving gear 732 is disposed on the piston rod of the moving motor 731, and the driven rack 733 is disposed on one side of the material guiding trough 71 and meshes with the driving gear 732. By driving the driving gear 732 to rotate through the moving motor 731, the material guiding trough 71 can move along the length direction of the support frame 72 under the meshing action of the driving gear 732 and the driven rack 733. This ensures that the material guiding trough 71 does not obstruct the collection of waste materials. When collecting finished products, the material guiding trough 71 is extended to facilitate the introduction of finished products into the finished product collection box 16.

[0035] Reference Figure 4 , Figure 5 As shown, a baffle 711 is hinged to one end of the guide trough 71 facing the finished product collection box 16. A spring plate 712 is connected between the baffle 711 and the guide trough 71. The spring plate 712 can drive the baffle 711 to be perpendicular to the bottom wall of the guide trough 71. A toggle bar 713 is provided at the bottom of the baffle 711. When the guide trough 71 moves towards the finished product collection box 16, the toggle bar 713 abuts against the worktable 1 and drives the baffle 711 to flip and open the opening of the guide trough 71. An obstacle groove 17 is provided on the worktable 1 for the baffle 711 to rotate. When no external force is applied, the baffle 711 closes the opening of the guide trough 71 under the action of the spring plate 712, so that the finished material will not leak out of the opening during the movement of the guide trough 71. When the guide trough 71 moves to the point where the actuating bar 713 abuts against the worktable 1 under the drive of the moving component 73, the actuating bar 713 can drive the baffle 711 to flip and open the opening of the guide trough 71, so that the finished material can fall into the finished product collection box 16.

[0036] Reference Figure 4 , Figure 6 As shown, the cutting head 12 is equipped with an air blowing mechanism 8 for blowing waste material into the waste collection box 15. After cutting, when the flipping mechanism 4 drives the suction mechanism 3 to flip, most of the waste material can fall into the waste collection box 15 under gravity. A small amount of waste material will remain on the suction mechanism 3, and the air blowing mechanism 8 can blow off this part of the waste material. The air blowing mechanism 8 includes an air blowing fan 81 and an air blowing pipe 82. An adjusting member 83 for adjusting the angle of the air blowing pipe 82 is provided on one side of the cutting head 12. The adjusting member 83 includes an adjusting rod 831 and a ball joint seat 832 provided at the end of the adjusting rod 831. The air blowing pipe 82 includes a flexible section 821 and a rigid section 822. A ball joint head 823 is provided on the rigid section 822, and the ball joint head 823 is hinged in the ball joint seat 832. By changing the position of the ball joint head 823 within the ball joint seat 832, the direction of the rigid section 822 can be adjusted, thereby allowing the outlet end of the rigid section 822 to blow air at an appropriate position.
