Description

Technical Field

[0001] This invention relates to the field of lens manufacturing and processing technology, and in particular to a lens grinding device and lens processing equipment. Background Technology

[0002] In the fields of optical instruments, laser systems, telescopes, and microscopes, the devices contain a variety of lenses. Before being assembled into these devices, the lenses need to undergo multiple processing steps such as grinding, polishing, and lapping.

[0003] In existing technologies, the lens grinding process typically involves using a suction pen to apply a drop of grinding fluid to the lens to be processed, followed by grinding with a grinding rod. The suction pen usually requires two control devices (such as pneumatic or electric cylinders): one for lateral movement between the grinding fluid tank and the lens, and the other for vertical extension and retraction. The grinding rod, on the other hand, requires three control devices: one for lateral movement between the cleaning tank and the lens, one for vertical extension and retraction, and one for rotation. Expanding production requires equipping each suction pen and grinding rod with the same movement devices, which is not cost-effective and makes wiring and repairing the large number of electrical components extremely complicated. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a lens grinding device, which aims to solve the technical problems in the prior art, where if the production scale of lens grinding needs to be expanded, each suction pen and grinding rod needs to be equipped with the same moving device, which is not conducive to cost control, and the wiring and repair of the large electrical components are also very complicated.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A lens grinding apparatus includes a fixed cylinder and a rotating cylinder coaxially arranged with the fixed cylinder. The rotating cylinder rotates intermittently on the fixed cylinder via a rotating assembly. Multiple liquid-absorbing components and grinding components are arranged in a circular array along the fixed cylinder, and the liquid-absorbing components and grinding components are alternately arranged. The liquid-absorbing components and grinding components are elastically connected to the rotating cylinder via a first elastic element and a second elastic element, respectively. The fixed cylinder has a wave groove with varying heights and multiple lowest points. The liquid-absorbing components and grinding components slide in the wave groove. Below the multiple lowest points, a preparatory station and a lens placement slot for holding lenses to be processed are alternately arranged. The rotating cylinder drives the liquid-absorbing components and grinding components to move in the wave groove, so that the liquid-absorbing components and grinding components alternately pass through the lowest points to reach the preparatory station and the lens placement slot.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0008] By setting up a fixed cylinder and a rotating cylinder that rotates around the fixed cylinder, when the liquid suction component and the grinding component on the rotating cylinder slide along the corrugated groove of the fixed cylinder, the first elastic element and the second elastic element can move them up and down, so that the liquid suction component and the grinding component alternately pass through the preparatory station located at the lowest point of the corrugated groove and the lens placement groove, thereby realizing four sets of actions in sequence: the liquid suction component absorbs the grinding liquid, the liquid suction component drips the grinding liquid onto the lens in the lens placement groove, the grinding component cleans itself, and the grinding component grinds the lens in the lens placement groove. The rotating component controls the rotating cylinder to rotate intermittently. When the liquid suction component and the grinding component are at the lowest point of the corrugated groove, the rotating cylinder stops to allow sufficient time to complete the above four sets of actions. This invention can set up multiple sets of liquid suction components and grinding components as needed, and reasonably control the shape of the corrugated groove to realize the simultaneous operation of multiple stations, without the need to equip each liquid suction component and grinding component with multiple moving devices, thereby reducing costs and improving processing efficiency.

[0009] According to one aspect of the above technical solution, the preparatory station includes an adjacent grinding fluid tank and a cleaning tank, wherein the grinding fluid tank is used to hold grinding fluid and the cleaning tank is used to hold clean water.

[0010] According to one aspect of the above technical solution, the liquid aspiration assembly includes a first connecting rod connected to the first elastic element and a suction pen connected to the first connecting rod. The suction pen is used to aspirate the grinding liquid. The grinding assembly includes a second connecting rod connected to the second elastic element and a third connecting rod connected to the second connecting rod. The third connecting rod is arranged vertically, and a horizontally arranged swing rod is connected to the lower part of the third connecting rod through a torsion elastic element. One end of the swing rod is connected to a grinding rod. A pressing rod is provided on the fixed circle near the preparatory position. The end of the swing rod away from the grinding rod contacts the pressing rod, so that the swing rod rotates around the third connecting rod as an axis.

[0011] According to one aspect of the above technical solution, with the rotating cylinder as the center, the position of the suction pen, the position of the grinding rod when the swing rod is not in contact with the pressing rod, the position of the lens placement groove, and the position of the grinding liquid groove are all located at the first arc, and the position of the grinding rod and the position of the cleaning groove when the swing rod is in contact with the pressing rod are all located at the second arc.

[0012] According to one aspect of the above technical solution, the grinding rod includes a housing fixedly connected to the swing rod, a rotating rod located inside the housing, a grinding block located below the rotating rod, and a first motor for controlling the rotation of the rotating rod and the grinding block. The grinding rod is provided with an infrared sensor for sensing the lens and the cleaning tank. When the infrared sensor senses the lens or the cleaning tank, the infrared sensor sends an electrical signal to cause the first motor to rotate.

[0013] According to one aspect of the above technical solution, the lens grinding device further includes a base, on which a spiral slide rail is installed at a position corresponding to the lens placement slot. A slide rail cylinder that slides along the spiral slide rail is fixed to the bottom of the lens placement slot. A stop portion is provided at both the starting end and the ending end of the spiral slide rail. A sensor is provided in the stop portion. The slide rail cylinder contacts the sensor to change the movement direction of the slide rail cylinder.

[0014] According to one aspect of the above technical solution, a third elastic element is provided vertically between the rotating rod and the grinding block, and the grinding block contacts the concave and convex surfaces of the lens at different horizontal heights, so as to deform the third elastic element.

[0015] According to one aspect of the above technical solution, the rotating assembly includes a first rotating shaft located at the center of the rotating cylinder, an intermittent gear located on the outer cylindrical surface of the first rotating shaft, a one-way gear meshing with the intermittent gear, and a second motor driving the first rotating shaft to rotate. The inner wall of the rotating cylinder is provided with an annular rack meshing with the one-way gear. When the intermittent gear disengages from the one-way gear, both the liquid suction assembly and the grinding assembly are located at the lowest point of the wave groove.

[0016] According to one aspect of the above technical solution, the rotating assembly includes a fixed structure connected to the rotating cylinder and a third motor that drives the fixed structure to rotate intermittently about the axis of the rotating cylinder.

[0017] The present invention also provides a lens processing apparatus, including the lens grinding device described above. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Example 1

[0032] Please see Figures 1 to 6The image shows a lens grinding apparatus according to a first embodiment of the present invention, including a fixed cylinder 30 and a rotating cylinder 40 coaxially arranged with the fixed cylinder 30. The rotating cylinder 40 rotates intermittently on the fixed cylinder 30 via a rotating assembly 50. In this embodiment, the rotating cylinder 40 is mounted on the fixed cylinder 30. The rotating cylinder 40 includes a first slider 41 located on the bottom surface and a second slider 42 located on the side wall. The fixed cylinder 30 is correspondingly provided with a first groove 31 for sliding the first slider 41 and a second groove 32 for sliding the second slider 42, so as to ensure the stability of the rotating cylinder 40 when rotating on the fixed cylinder 30.

[0033] Specifically, the lens grinding device also includes an upper top plate 10 fixed at a point on the production line, and the fixed cylinder 30 is fixed below the upper top plate 10 by a ring of spaced fixing rods.

[0034] Furthermore, a plurality of liquid-absorbing components 60 and grinding components 70 are arranged in a ring array along the fixed cylinder 30. The liquid-absorbing components 60 and the grinding components 70 are arranged alternately. The liquid-absorbing components 60 and the grinding components 70 are elastically connected to the rotating cylinder 40 through a first elastic member 61 and a second elastic member 71, respectively. The distance between the liquid-absorbing components 60 and the grinding components 70 is equal in arc length.

[0035] In this embodiment, there are two liquid suction components 60 and two grinding components 70. In some other embodiments, there may be multiple liquid suction components 60 and multiple grinding components 70, but the number of both must be consistent.

[0036] Furthermore, the fixed cylinder 30 has a wavy groove 35 with varying heights through its wall. The wavy groove 35 has multiple lowest points. The liquid absorption assembly 60 and the grinding assembly 70 slide in the wavy groove 35. Below the multiple lowest points, a preparation station 80 and a lens placement slot 90 for holding the lens to be processed are alternately provided. The rotating cylinder 40 drives the liquid absorption assembly 60 and the grinding assembly 70 to move in the wavy groove 35, so that the liquid absorption assembly 60 and the grinding assembly 70 alternately pass through the lowest points to reach the preparation station 80 and the lens placement slot 90.

[0037] Understandably, by setting up a fixed cylinder 30 and a rotating cylinder 40 that rotates around the fixed cylinder 30, when the liquid suction component 60 and the grinding component 70 on the rotating cylinder 40 slide along the corrugated groove 35 of the fixed cylinder 30, the first elastic element 61 and the second elastic element 71 can move them up and down, so that the liquid suction component 60 and the grinding component 70 alternately pass through the preparatory station 80 located at the lowest point of the corrugated groove 35 and the lens placement groove 90, thereby sequentially realizing the liquid suction component 60 absorbing the grinding liquid, the liquid suction component 60 dripping the grinding liquid onto the lens in the lens placement groove 90, and the cleaning of the grinding component 70 itself. The invention comprises four sets of actions: grinding the lens in the lens placement groove 90 by the grinding component 70, and intermittent rotation of the rotating cylinder 40 controlled by the rotating component 50. When the liquid suction component 60 and the grinding component 70 are at the lowest point of the wave groove 35, the rotating cylinder 40 is stopped to allow sufficient time to complete the above four sets of actions. The invention can set multiple sets of liquid suction components 60 and grinding components 70 as needed and reasonably control the shape of the wave groove 35 to realize the simultaneous operation of multiple workstations. Moreover, it does not require multiple moving devices for each liquid suction component 60 and grinding component 70, which reduces costs and improves processing efficiency.

[0038] Specifically, the preparation station 80 includes an adjacent grinding liquid tank 81 and a cleaning tank 82. The grinding liquid tank 81 is used to hold grinding liquid, and the cleaning tank 82 is used to hold clean water. The liquid suction assembly 60 includes a first connecting rod 62 connected to the first elastic member 61 and a suction pen 63 connected to the first connecting rod 62. The suction pen 63 is used to suction the grinding liquid. The grinding assembly 70 includes a second connecting rod 72 connected to the second elastic member 71 and a third connecting rod 73 connected to the second connecting rod 72. The third connecting rod 73 is vertically arranged, and a horizontally arranged swing rod 75 is connected to the lower part of the third connecting rod 73 through a torsion elastic member 74. One end of the swing rod 75 is connected to a grinding rod 76. A pressing rod 33 is provided on the fixed circle near the preparation station 80. The end of the swing rod 75 away from the grinding rod 76 contacts the pressing rod 33 so that the swing rod 75 rotates around the third connecting rod 73 as an axis.

[0039] With the rotating cylinder 40 as the center, the positions of the suction pen 63, the grinding rod 76 when the swing rod 75 is not in contact with the pressing rod 33, the lens placement groove 90, and the grinding liquid groove 81 are all located at the first arc. When the swing rod 75 is in contact with the pressing rod 33, the positions of the grinding rod 76 and the cleaning groove 82 are all located at the second arc.

[0040] Understandably, before operation, both the suction pen 63 and the polishing rod 76 are located at the highest point of the wave groove 35. Then, the rotating component 50 is activated to rotate the rotating cylinder 40 on the fixed cylinder 30, causing both the suction pen 63 and the polishing rod 76 to move downwards along the wave groove 35. The first elastic element 61 and the second elastic element 71 are stretched until both the suction pen 63 and the polishing rod 76 are located at the lowest point. At this time, the suction pen 63 is located at the polishing liquid tank 81, and the polishing rod 76 is located at the lens placement tank 90. ​​At this time, the lens placement tank 90 is not yet loaded with a film. Then, the rotating component 50 is used to pause the rotation of the fixed cylinder 30, allowing the suction pen 63 and the polishing rod 76 sufficient time to absorb the polishing liquid and polish the lens. After the above actions are completed, the rotating component 50 is controlled to drive the rotating cylinder 40 to continue rotating, so that the suction pen 63 and the polishing rod 76 can continue to move downwards along the wave groove 35. As the grinding rod 76 rotates to the lowest point of the next wave groove 35, the suction pen 63 is positioned at the lens placement groove 90 to drip the previously collected polishing liquid onto the lens. Before the grinding rod 76 reaches the lowest point, the swing rod 75 contacts the pressing rod 33, causing the swing rod 75 to rotate at a certain angle at the torsion elastic element 74, so that the grinding rod 76 is positioned precisely at the cleaning groove 82 to clean the grinding rod 76 after polishing the lens, thus avoiding affecting the polishing of the next lens. As the grinding rod 76 continues to rotate along the wave groove 35, the swing rod 75 rotates to disengage from the pressing rod 33 and resets through the torsion elastic element 74. This process is repeated to complete the above actions, enabling multiple suction pens 63 and grinding rods 76 to operate synchronously without the need for multiple moving devices for each suction pen 63 and grinding rod 76.

[0041] Furthermore, the polishing rod 76 includes a housing 762 fixedly connected to the swing rod 75, a rotating rod 763 located inside the housing 762, a polishing block 765 located below the rotating rod 763, and a first motor 761 for controlling the rotation of the rotating rod 763 and the polishing block 765. The polishing rod 76 is provided with an infrared sensor for sensing the lens and the cleaning tank 82. When the infrared sensor senses the lens or the cleaning tank 82, the infrared sensor sends an electrical signal to cause the first motor 761 to rotate.

[0042] Understandably, when the polishing rod 76 stops at the lowest point of the wave groove 35, it is either above the lens or above the cleaning tank 82. After the infrared sensor identifies the lens or the cleaning tank 82, it sends an electrical signal to control the rotation of the first motor 761 to polish the lens or clean itself. When the polishing rod 76 rotates to the point where it is no longer at the lowest point and the infrared sensor can no longer identify the lens or the cleaning tank 82, it sends an electrical signal to stop the rotation of the first motor 761.

[0043] According to one aspect of the above technical solution, the lens grinding device further includes a base 20, on which a spiral slide rail 91 is installed at a position corresponding to the lens placement groove 90. A slide rail cylinder 92 that slides along the spiral slide rail 91 is fixedly connected to the bottom of the lens placement groove 90. A stop portion 93 is provided at both the starting end and the ending end of the spiral slide rail 91. A sensor is provided inside the stop portion 93. The slide rail cylinder 92 contacts the sensor to change the movement direction of the slide rail cylinder 92.

[0044] Understandably, grinding requires covering every surface of the lens, typically starting from the center and working outwards. When the infrared sensor sends an electrical signal to drive the first motor 761, it also sends an electrical signal to move the slide rail cylinder 92. This causes the slide rail cylinder 92 to move the lens placement slot 90 along the spiral slide rail 91, making the lens rotate spirally and gradually contact the grinding block 765 from its center to its periphery, thus completing the uniform grinding of each point. When the slide rail cylinder 92 hits the stop 93 at the end, the sensor sends an electrical signal to the slide rail cylinder 92 to make it move in the opposite direction until the slide rail cylinder 92 hits the stop 93 at the beginning. The sensor at the stop 93 then sends an electrical signal to the slide rail cylinder 92 to stop it.

[0045] Preferably, a third elastic element 764 is provided vertically between the rotating rod 763 and the grinding block 765, and the grinding block 765 contacts the concave and convex surfaces of the lens at different horizontal heights so that the third elastic element 764 deforms.

[0046] Understandably, since one surface of the lens to be processed is uneven, by providing a third elastic element 764 vertically between the rotating rod 763 and the grinding block 765 to play a pressing role, the grinding block 765 can adjust its tightness when it comes into contact with the lens to be processed, thereby improving the grinding quality.

[0047] Specifically, in this embodiment, the rotating assembly 50 includes a first rotating shaft 52 located at the axis of the rotating cylinder 40, an intermittent gear 51 located on the outer cylindrical surface of the first rotating shaft 52, a one-way gear 53 meshing with the intermittent gear 51, and a second motor (embedded in the upper top plate 10, not shown in the figure) that drives the first rotating shaft 52 to rotate. The inner wall of the rotating cylinder 40 is provided with an annular rack 54 that meshes with the one-way gear 53. When the intermittent gear 51 disengages from the one-way gear 53, the liquid suction assembly 60 and the grinding assembly 70 are both located at the lowest point of the wave groove 35.

[0048] Understandably, in specific operation, the second motor is started, causing its motor shaft to drive the first rotating shaft 52 to rotate slowly. When the toothed part of the intermittent gear 51 contacts the one-way gear 53, it will drive the one-way gear 53 to rotate. The rotation of the one-way gear 53 will drive the ring rack 54 to rotate, thereby causing the rotating cylinder 40 to rotate. When the toothed part of the intermittent gear 51 disengages from the one-way gear 53, the one-way gear 53 and the ring rack 54 will not rotate, thus achieving intermittent rotation of the rotating cylinder 40. By controlling the stroke between each gear and rack, when the toothed part of the intermittent gear 51 just disengages from the one-way gear 53, the suction pen 63 and the grinding rod 76 are exactly above the preparatory station 80 and the lens placement slot 90. The one-way gear 53 will only rotate in one direction. When the toothed part of the intermittent gear 51 disengages from the one-way gear 53, the one-way gear 53 can hold the ring rack 54, preventing the ring rack 54 from rotating in the opposite direction due to the rebound force of the first elastic element 61 and the second elastic element 71.

[0049] In summary, the lens grinding apparatus in the above embodiments of the present invention, by setting a fixed cylinder and a rotating cylinder that rotates around the fixed cylinder, allows the liquid suction component and the grinding component on the rotating cylinder to slide along the corrugated groove of the fixed cylinder. The first and second elastic elements enable them to move up and down, allowing the liquid suction component and the grinding component to alternately pass through the preparatory station located at the lowest point of the corrugated groove and the lens placement groove. This sequentially achieves four sets of actions: the liquid suction component absorbing the grinding liquid, the liquid suction component dripping the grinding liquid onto the lens in the lens placement groove, the cleaning of the grinding component itself, and the grinding component grinding the lens in the lens placement groove. The rotating component controls the rotating cylinder to rotate intermittently. When the liquid suction component and the grinding component are at the lowest point of the corrugated groove, the rotating cylinder stops to allow sufficient time to complete the above four sets of actions. The present invention can set multiple sets of liquid suction components and grinding components as needed, and reasonably control the shape of the corrugated groove to achieve simultaneous operation of multiple stations. Furthermore, it eliminates the need to equip each liquid suction component and grinding component with multiple moving devices, reducing costs while improving processing efficiency.

[0050] Example 2

[0051] Please refer to Figure 7 The image shows a lens grinding device in the second embodiment of the present invention. The lens grinding device in this embodiment differs from the lens grinding device in the first embodiment in that the rotating component 50 includes a fixed structure 55 connected to the rotating cylinder 40, and a third motor (located inside the upper top plate, not shown in the figure) that drives the fixed structure 55 to rotate intermittently around the axis of the rotating cylinder 40.

[0052] Understandably, the motor shaft of the third motor can also directly control the rotation of the rotating cylinder 40 through the fixed structure 55. However, the third motor needs to be set to rotate intermittently so that when the third motor just stops rotating, the liquid suction component 60 and the grinding component 70 are exactly at the lowest point of the wave groove 35.
