[0030] like Figure 13-Figure 15As shown, during the processing of the lens in the rubidium atomic clock gas chamber lens, the lens is easily rubbed by the cutting tool 98, which may cause glass fragments to splash. At the same time, the lens and the cutting tool 98 also generate a lot of heat due to friction. At the same time, after the lens is cut, glass fragments are still left on its cutting surface. Most of these situations require manual operation, and there is no automatic water spray lubrication, cooling and cleaning function. The other side of the top frame 4 is provided with an auxiliary component 10 used in conjunction with the placement frame 5, and the auxiliary component 10 includes a three-way valve 101 connected to the other end of the pressure storage tank 78.

The impurities in the waste water are doubly intercepted and filtered, which is beneficial to the recycling of the waste liquid.

[0031] The working principle of a lens cutting and forming device for a miniature rubidium atomic clock gas chamber integrated optical lens is as follows: first, four lenses to be cut are placed on four groups of supporting rings 91 in a placement frame 5, and then the first electric push rod 62 is controlled to start and drive the first main bevel gear 63 to be clamped to the meshing portion of the first sub-bevel gear 64, and then the double-headed motor 61 is controlled to start and drive the first sub-bevel gear 64 to rotate through the first main bevel gear 63 that is meshed in place, and the first sub-bevel gear 64 drives the cam frame 65 to rotate accordingly, and under the elastic buffering and elastic reset cooperation of the four reset springs 68, the cam frame 65 drives the pistons 67 on the four push rod frames 66 to rotate in the four groups of pistons The four push rod frames 66 perform reciprocating work in the cylinder 2. When the pistons 67 on the four push rod frames 66 follow the cam frame 65 to move to the innermost end under the elastic restoring force of the four restoring springs 68, the four groups of pistons 67 are in the return suction state in the four groups of piston cylinders 2. At this time, the first electric control valve 73 on the four negative pressure suction pipes 72 is controlled to open, and the second electric control valve 76 on the four auxiliary suction pipes 75 and the exhaust valve 11 on the four exhaust pipes 77 are closed. Then, the negative pressure suction force generated by the four groups of pistons 67 in the four groups of piston cylinders 2 is used by the four negative pressure suction pipes 72 through the four groups of negative pressure suction ports 71 to perform synchronous negative pressure adsorption positioning operations on the four lenses on the four groups of supporting rings 91. After the four lenses on the four groups of supporting rings 91 complete the negative pressure positioning operation, the first electrically controlled valves 73 on the four negative pressure suction pipes 72 are controlled to be closed, so that the four negative pressure suction pipes 72 maintain a continuous negative pressure adsorption state for the four lenses, and the second electrically controlled valves 76 on the four auxiliary suction pipes 75 are controlled to be opened, so that the outside air is sucked into the four groups of piston cylinders 2 through the three-way pipes 74 on the four auxiliary suction pipes 75, providing another suction channel support for the four groups of piston cylinders 2. When the cam frame 65 rotates to the outermost end, the pistons 67 on the four push rod frames 66 are squeezed by the outermost end of the cam frame 65, forcing the four return springs 68 to be compressed synchronously. , the four groups of pistons 67 are in the exhaust state in the four groups of piston cylinders 2. On the contrary, the first electric control valve 73 on the four negative pressure suction pipes 72 and the second electric control valve 76 on the four auxiliary suction pipes 75 are controlled to be closed, and the exhaust valve 11 on the four exhaust pipes 77 is opened. Then, the air source in the four groups of piston cylinders 2 is squeezed by the four groups of pistons 67 and supplied to the pressure storage tank 78 through the four exhaust pipes 77 for temporary storage. When the pressurized air source in the pressure storage tank 78 reaches the upper limit, the double-headed motor 61 is controlled to pause first, and then the first electric push rod 62 is controlled to close and drive the first main bevel gear 63 to disengage from the meshing portion of the first sub-bevel gear 64 to the initial position; Next, the second electric push rod 82 is controlled to open and drive the second main bevel gear 83 to the meshing part of the second sub-bevel gear 84, and then the double-headed motor 61 is controlled to open again and drive the second sub-bevel gear 84 to rotate through the second main bevel gear 83 that is meshed in place. With the rotation support of the driven ring gear 87 provided by the T-shaped slide 88 and the T-shaped slide groove 81, the second sub-bevel gear 84 drives the driven ring gear 87 to rotate at a uniform speed through the driving circular gear 86 on the rotating rod 85, and the driven ring gear 87 drives the slide seat 93 to rotate at a uniform speed in the arc-shaped slide mouth 92. The slide seat 93 drives the industrial camera 95, the electric cylinder 96, the drive motor 97 and the cutting tool 98 to rotate in sequence around the four groups of supporting rings 91 through the bracket 94, so as to achieve the above-mentioned operation. Starting from the lens on the first group of supporting rings 91, and after the cutting tool 98 reaches the top of the first group of lenses, the electric cylinder 96 is controlled to start and the cutting tool 98 is driven by the driving motor 97 to move down to the cutting surface of the first group of lenses, and then the driving motor 97 is controlled to start and drive the cutting tool 98 to perform cutting operations on the first group of lenses, and so on, until the continuous and efficient cutting of the four lenses is completed, the double-headed motor 61 is controlled to pause first, and then the second electric push rod 82 is controlled to close and drive the second main bevel gear 83 to disengage from the meshing part of the second sub-bevel gear 84 to the initial position, and the next round of cutting of the four lenses is started. After the next round of reverse indexing adjustment is started with the fourth lens as the starting point, the four lenses are continuously cut; Before and after the cutting tool 98 cuts the four lenses, the three-way valve 101 is opened first, and the pressurized air source in the pressure storage tank 78 is supplied to the three-way valve 101. At the same time, the water in the water bucket 103 is also supplied to the three-way valve 101 and merged with the pressurized air source to form a pressurized water source. The flow rate of the pressurized water source formed in the three-way valve 101 is monitored in real time by the flow meter 102, and the level meter 104 monitors the clean water level in the water bucket 103 in real time. The pressurized water source in the three-way valve 101 is quantitatively sprayed to the cutting tool 98 and the four lens areas through the four water spray heads 106 on the pressure pipe 105, and the four groups of baffles 13 are used to control the four lenses. The debris and water source splashed by cutting play a blocking role. At the same time, the water sprayed by the water spray head 106 plays a role of water spraying lubrication and cooling for the lens in the cutting state, and also plays a role of water spraying and cleaning for impurities remaining on the surface of the lens after cutting. After the lens cleaning is completed, the water bucket 103 is controlled to stop adding water, and the pressurized air source is blown dry to the four lenses through the water spray head 106. The large particles of impurities in the wastewater in the water collection tank 12 are first pre-intercepted by the stepped leakage hole 107, and then finely filtered by the filter screen 108 in the water collection cover 14. The clear wastewater after double interception and filtration is discharged through the sewage pipe for recycling.
