Description

Technical Field

[0001] The invention belongs to the technical field of prism processing, and in particular relates to a laser chamfering device for chamfering the edge of a prism. Background Art

[0002] A prism is a polyhedron made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. For example, in spectral instruments, the "dispersion prism" that decomposes composite light into a spectrum is commonly an equilateral prism; in instruments such as periscopes and binoculars, the "total reflection prism" that changes the direction of light and thus adjusts its imaging position is generally a right-angle prism;

[0003] During the prism production process, it is usually necessary to chamfer the edges of the prism to remove the corresponding sharp edges. At present, the common method of processing chamfers is for workers to hold the lens and grind it manually on the grinding wheel. This processing method has extremely poor controllability, which will cause uncertainty in the grinding amount and uncontrollable angles, that is, the chamfered edge processed has too much chamfer on one side and too little chamfer on the other side. Therefore, the chamfers processed in this way have poor consistency and do not meet the quality requirements of customers. In addition, due to the high-speed rotation of the grinding wheel, it is easy to hurt fingers. At the same time, during the grinding process, it is necessary to constantly observe whether the grinding is in place, which has low work efficiency.

[0004] In the prior art, the Chinese utility model with publication number: CN211916356U discloses a prism chamfering device, which relates to the technical field of optical prism chamfering equipment. It includes a grinder, which includes a horizontally arranged grinding disc and a main body for driving the grinding disc to rotate, and the grinding disc is arranged on the top of the main body; it also includes a support table, the bottom of which is provided with height-adjustable support feet, and the middle part of which has a vertically through-going working area, the support table is arranged on the top of the main body, and the grinding disc is located in the working area; and a left crossbeam and a right crossbeam are arranged in parallel in the working area of ​​the support table, and the left crossbeam and the right crossbeam are respectively provided with a left support body and a right support body on the opposite sides of the left crossbeam and the right support body. The support surfaces on the opposite sides of the left support body and the right support body are matched at a "V"-shaped angle to support the prism to be processed. The utility model is provided with a height-adjustable support table, thereby changing the amount of edge lowering when the prism is chamfered, and then changing the amount of chamfering grinding. It can be applied to the processing of different prisms and chamfers of different specifications, and the operation is simple and efficient.

[0005] Although the above technical solution can improve the consistency of prism chamfering, it still requires workers to hold the prism for chamfering, and the amount of operation before chamfering the prism is high, the degree of automation of prism chamfering is low, and the efficiency of prism chamfering needs to be further improved.

The first motor 37 drives the driving bevel gear 38 to engage the driven bevel gear 39, so that the synchronous wheel 35 drives the synchronous belt 36 to adjust the position of the moving seat 310, thereby facilitating the horizontal position adjustment of the CO2 laser 9 and chamfering the prism edge.

[0034] The laser adjustment mechanism 3 also includes a first motor 37 installed on one side of the inner cavity of the first mounting frame 31 and two groups of limit columns 33 fixedly connected to the top of the inner cavity of the chassis 1.

The limit columns 33 ensure the stability of the first mounting frame 31 in the lifting and lowering adjustment of the CO2 laser 9, thereby improving the quality of the chamfering of the prism edge processed by the CO2 laser 9.

[0035] As shown in question 4, the prism positioning and flipping mechanism 4 includes a second cylinder 41 fixedly connected to both sides of the inner cavity of the chassis 1, the telescopic ends of the two groups of second cylinders 41 are fixedly connected to the second mounting bracket 42, one side of the two groups of second mounting brackets 42 are rotatably connected to a connecting shaft 45, one end of the connecting shaft 45 is fixedly connected to a positioning clip 47, and the second mounting bracket 42 is driven to move by the second cylinder 41, so that the positioning clip 47 can clamp the prism, thereby improving the stability of the prism under the CO2 laser 9 processing.

[0037] like Figure 5As shown, the loading and unloading mechanism 5 includes a support frame 52, an loading and unloading plate 56 and two groups of third motors 57. The inner cavity of the support frame 52 is fixedly connected with two groups of guide rods 55 for sliding connection of the loading and unloading plates 56. The two groups of third motors 57 are installed at both ends of the lower surface of the loading and unloading plates 56. The output shafts of the two groups of third motors 57 are both transmission-connected with adjusting gears 58. Tooth plates 59 for meshing with the adjusting gears 58 are fixedly connected on both sides of the inner cavity of the support frame 52. The adjusting gear 58 is driven by the third motor 57 to engage with the tooth plate 59, thereby facilitating the adjustment of the position of the loading and unloading plates 56, and facilitating and quickly adjusting the position of the prism transfer mechanism 6, thereby improving convenience.

[0038] The loading and unloading mechanism 5 also includes two groups of first hinges 51, two groups of second hinges 54 and two groups of third cylinders 53. The two groups of first hinges 51 are fixedly connected to the inner cavity of the chassis 1, and the two groups of second hinges 54 are respectively rotatably connected to the two sides of the support frame 52. The two groups of third cylinders 53 are respectively rotatably connected to the two groups of first hinges 51. The telescopic ends of the two groups of third cylinders 53 are respectively fixedly connected to the two groups of second hinges 54. The telescopic ends of the third cylinders 53 are reset to change the support frame 52 from a horizontal state to an inclined state, thereby avoiding affecting the deployment of the material receiving mechanism 7.

[0039] like Figure 6 As shown, the prism transfer mechanism 6 includes a fourth cylinder 61, a support plate 62 and a prism corner plate 64. The fourth cylinder 61 is installed on the lower surface of the upper and lower material plates 56. The telescopic end of the fourth cylinder 61 passes through the upper and lower material plates 56 and is fixedly connected to the lower surface of the support plate 62. The upper surface of the support plate 62 is provided with two groups of slide grooves 69 for sliding connection of the prism corner plate 64. Both ends of the lower surface of the support plate 62 are fixedly connected with the fifth cylinder 63. One side of the prism corner plate 64 is fixedly connected with a convex plate 68 for fixing the telescopic ends of the two groups of fifth cylinders 63. The fifth cylinder 63 is used to facilitate the movement of the position of the prism corner plate 64, so that the prism corner plate 64 can be extended out of the chassis 1 to facilitate the staff to take and place the prism, thereby improving the efficiency of taking and placing the prism.

[0040] A plurality of groups of air suction holes 66 are provided on the upper surface of the prism corner plate 64, and an air suction valve 65 is provided on one side of the prism corner plate 64 adjacent to the two groups of convex plates 68. The vertical cross-section of the prism corner plate 64 is L-shaped, and the prism corner plate 64 is hollow. A pressure sensor 67 is embedded on the upper surface of the prism corner plate 64. The pressure sensor 67 detects whether the prism is placed on the prism corner plate 64, so that the pressure sensor 67 transmits a signal to the control system 2 after detecting the pressure, and the control system 2 controls the air suction valve 65 to open, thereby reducing the pressure in the prism corner plate 64, facilitating the adsorption of the prism through the air suction holes 66, and improving the stability of the prism movement.

[0041] like Figure 7As shown, the material receiving mechanism 7 includes two groups of screw rods 71, two groups of pulling blocks 73 and multiple groups of material receiving stacking plates 74. The two groups of screw rods 71 ​​are rotatably connected to the inner cavity of the chassis 1, and the two groups of pulling blocks 73 are respectively threadedly connected to one end of the two groups of screw rods 71, and the two groups of pulling blocks 73 are arranged in the same plane. One end of the two groups of screw rods 71 ​​passes through the chassis 1 and is driven by the fourth motor 72. The two adjacent groups of material receiving stacking plates 74 are slidingly connected, and the upper end of one group of material receiving stacking plates 74 is rotatably connected to the lower ends of the two groups of pulling blocks 73, and the lower end of the other group of material receiving stacking plates 74 is rotatably connected to the upper end of the collecting hopper 8. The fourth motor 72 drives the screw rod 71 to adjust the pulled position, so that the pulling block 73 drives the material receiving stacking plate 74 to unfold, so as to separate the prism and the loading and unloading mechanism 5, avoid the debris generated by the chamfering of the prism from accumulating in the chassis 1, and improve the cleanliness of the chassis 1.

[0042] like Figure 1-2 As shown, a double door is provided on the side adjacent to the chassis 1 and the control system 2, an observation window is provided on the upper end of the chassis 1 on the same side as the double door, and a discharge hole connected to the collecting hopper 8 is provided at the lower end of the chassis 1 on the side opposite to the control system 2. The cross-section of the collecting hopper 8 is arranged in a right-angle trapezoid. Through the inclined observation window on the chassis 1, the process of prism chamfering can be observed, and then the programming of the control system 2 (which is the prior art, composed of the prior art such as the controller, the information transceiver and the power supply) can be quickly adjusted. At the same time, the debris generated by the chamfering is centrally processed through the collecting hopper 8, thereby improving the efficiency of processing the debris.

[0043] When the device is stationary, the loading and unloading mechanism 5 is in a horizontal state, and the receiving mechanism 7 is in a storage state (the multiple sets of receiving stacking plates 74 are all in a vertical state with the horizontal plane);

[0044] When the device is used to chamfer a prism, the double doors of the chassis 1 are opened, and the control system 2 controls the third motor 57 to drive the adjusting gear 58 to rotate, thereby driving the position of the prism transport mechanism 6 on the loading and unloading plate 56 to adjust the position, so that the prism transport mechanism 6 moves to the double door position, and then the fifth cylinder 63 starts the abutting convex plate 68 to make the prism corner plate 64 extend out of the chassis 1, so that the staff can place the prism to be chamfered on the prism corner plate 64 and abut against one side of the prism corner plate 64;

[0045] After the pressure sensor 67 detects the continuous pressure for 3-5s, it transmits a signal to the control system 2, and the air suction valve 65 extracts the air in the prism corner plate 64 through the air pump (not shown in the figure), so that the prism is adsorbed by the multiple groups of air suction holes 66 under the action of negative pressure, and then the control system 2 controls the fifth cylinder 63 to reset, so as to ensure the stability of the prism when the prism transport mechanism 6 moves;

[0046] When the third motor 57 rotates in reverse to reset the loading and unloading plates 56 to the bottom of the laser adjustment mechanism 3, the fourth cylinder 61 lifts the support plate 62 to place the prism corner plate 64 in the prism positioning and flipping mechanism 4, and the air intake valve 65 is closed to balance the pressure in the prism corner plate 64, thereby removing the adsorption force on the prism, and the telescopic end of the second cylinder 41 extends to make the positioning clip 47 contact and clamp the two ends of the prism, and the double door is closed at the same time;

[0047] After the prism is clamped, the fourth cylinder 61 is reset, and the telescopic end of the third cylinder 53 is retracted, and the support frame 52 and the end of the inlet hole (double door installation hole) of the chassis 1 are flipped, so that the support frame 52 is flipped to the bottom of the chassis 1, and at the same time, the control system 2 controls the fifth motor to drive the screw rod 71 to rotate, so that the screw rod 71 drives the pull block 73 to move, so that the multiple groups of material stacking plates 74 are unfolded, and the loading and unloading mechanism 5 and the prism positioning and flipping mechanism 4 are separated;

[0048] The telescopic end of the first cylinder 34 is controlled to be telescopic by the control system 2, thereby adjusting the distance between the CO2 laser 9 and the edge of the prism. The laser power, speed and frequency of the CO2 laser 9 are adjusted by the control system 2 to first cut the edge of the prism, and then to split the edge to remove excess material. The first motor 37 drives the driving bevel gear 38 to engage the driven bevel gear 39 to drive the synchronous belt 36 to rotate, thereby adjusting the position of the moving seat 310, so as to facilitate the adjustment of the position of the CO2 laser 9, thereby facilitating the chamfering of the edge of the prism. At the same time, a guide rail (not shown in the figure) for the sliding connection of the moving seat 310 is provided at the top of the first mounting frame 31 to ensure the stability of the moving seat 310 during movement, thereby ensuring the stability of the prism edge processing and improving the accuracy of the prism processing.

[0049] When one side of the prism is processed, the control system 2 controls the third motor 57 to drive the worm 43 to engage the worm wheel 46 on the connecting shaft 45, so that the connecting shaft 45 drives the positioning clip 47 to rotate the prism, so that the unprocessed corner of the prism is close to the CO2 laser 9, thereby realizing the efficiency of chamfering the prism edge without manual operation, thereby improving the efficiency of chamfering the prism edge;

[0050] The debris generated by the chamfering of the prism edge falls on the material receiving stacking plate 74, and then falls into the collecting hopper 8 for collection, which is convenient for quickly collecting the prism processing waste and reduces the cleaning workload of the staff. After the prism chamfering is completed, the control system 2 controls the material receiving mechanism 7 to reset, and at the same time the loading and unloading mechanism 5 rises, and the prism is supported by the prism transfer mechanism 6, and then the prism positioning and flipping mechanism 4 is reset to place the prism on the prism corner plate 64. After the pressure sensor 67 detects the prism pressure, the control system 2 pumps air to reduce the pressure in the prism corner plate 64, thereby adsorbing the prism, and the third motor 57 The driving adjustment gear 58 is meshed with the tooth plate 59, and the prism is transported to the double door. The staff opens the double door, and the telescopic end of the fifth cylinder 63 pushes out the prism corner plate 64, and then the air intake valve 65 is closed, so that the pressure inside and outside the prism corner plate 64 is balanced, so that the staff can take out the chamfered prism and facilitate the processing of the next prism, thereby improving the chamfering efficiency of the prism, and being able to quickly load and unload materials, thereby improving the degree of automation of the device, having a high production yield, effectively improving product quality, and effectively controlling the cross-sectional size of the chamfered edge and the roughness.
