Fig. 1 schematically shows a perspective structural layout of a milling device for an optical lens according to one embodiment of the invention. As shown in fig. 1, the milling device for an optical lens according to the present invention includes a milling unit 1, a dust collection unit 2, and a feed unit 3. In the present embodiment, the dust collection unit 2 is disposed next to the milling unit 1 and is fixedly connected to the milling unit 1.

The specific linear arrangement is not limited to the above embodiment, as long as it is possible to ensure that the milling cutter in the milling unit 1 and the stem of the optical lens are on the same straight line. In addition, in the present embodiment, the milling device for an optical lens further includes a control button unit a for controlling an operation state of the milling device.

In addition, fig. 1 shows two sets of milling devices of the optical lens according to the invention, wherein the two sets of milling devices are in different working states, such as the milling device near the left side in the figure is in a non-working state, namely, the state that the milling unit 1 and the material conveying unit 3 do not have matched butt joint processing. The milling device near the right side in the figure is in a working state, namely, a state that the material conveying unit 3 and the milling unit 1 are matched and in butt joint.

Fig. 2 schematically shows a perspective structural arrangement of a milling unit according to an embodiment of the invention. As shown in fig. 2, in the present invention, the milling unit 1 comprises a first driving mechanism 101, a second driving mechanism 102, and a milling mechanism 103. In the present embodiment, the first drive mechanism 101 is located at the lowermost side to provide support and linear drive for the second drive mechanism 102 and the milling mechanism 103. The second driving mechanism 102 is supported above the first driving mechanism 101, and can be linearly reciprocated by the driving of the second driving mechanism 102. As shown in fig. 2, a guide rail is provided in parallel with the first drive mechanism 101, and the second drive mechanism 102 is movable back and forth on the first drive mechanism 101 and the guide rail, and is movable in the left-right direction in fig. 2. Further, the milling mechanism 103 is supported on the second driving mechanism 102, and the milling mechanism 103 is linearly reciprocally movable by the second driving mechanism 102, the reciprocal movement being realized along the axial direction of the second driving mechanism 102, which is a movement in the front-rear direction in fig. 2. As a result, the milling mechanism 103 can be linearly reciprocated in the left-right direction as viewed in fig. 2 by the driving of the first driving mechanism 101 together with the second driving mechanism 102. Meanwhile, the milling mechanism 103 may also be linearly reciprocated in the front-rear direction as in fig. 2 by the driving of the second driving mechanism 102. Thus, the milling mechanism 103 has two directions of freedom of movement, which may be referred to as lateral movement and longitudinal movement. Because the milling mechanism 103 has transverse movement and longitudinal movement, the milling mechanism for actual machining in the milling unit can realize a required movement track in the working process of the milling device, so that the efficiency of milling the material handle of the optical lens is higher, and the time required for machining production is less; meanwhile, the first driving mechanism 101 and the second driving mechanism 102 can adopt a servo motor to drive the ball screw module to move, so that the moving precision is high, and the surface of the milled lens is smoother.

Furthermore, as shown in fig. 2, the milling unit 1 in the milling device for an optical lens according to the present invention comprises two sets of milling mechanisms 103 arranged side by side. The two milling mechanisms 103 can be operated simultaneously, so that the milling speed of the optical lens is doubled in the actual production process, and small-batch production can be realized. One of the milling mechanisms 103 is specifically described below:

as shown in fig. 2, the milling mechanism 103 includes a milling cutter 1031, a support base 1032, a mounting base 1033, a height adjustment handle 1034, and a cooling tube 1035.

The mounting block 1033 is fixedly mounted to the shank of the milling cutter 1031. The height adjustment handle 1034 is partially threaded through the mounting block 1033 and fixedly coupled to the mounting block 1033, and is partially threaded through the mounting block 1033 and threadably coupled to a threaded bore provided in the support block 1032. By this arrangement, the height adjustment handle 1034 can be screwed into and out of the supporting seat 1032 to drive the mounting seat 1033 to move up and down, so as to drive the milling cutter 1031 to move up and down, and adjust the height of the milling cutter 1031, i.e., adjust in the up and down direction in fig. 2. In this embodiment, the height adjustment handle 1034 may employ a precision adjustment measurement tool such as an outside micrometer.

As shown in fig. 2, in the present embodiment, the cooling pipe 1035 is disposed adjacent to the milling cutter 1031, and the nozzle of the cooling pipe 1035 is directed toward the cutter head of the milling cutter 1031, so that when the external air source is connected to the cooling pipe 1035, air can be directly blown to the working cutter head portion of the milling cutter 1031 through the cooling pipe 1035, and thus the milling cutter 1031 can be cooled from time to time, the phenomenon of sticking of the milling cutter 1031 is effectively prevented, and thus the phenomena of breakage and uneven surface of the lens are prevented.

Fig. 3 schematically shows a perspective structural arrangement of a feed unit according to an embodiment of the invention. As shown in fig. 3, the feeding unit 3 includes an adjusting mechanism 301, a lens carrying mechanism 302, a driving mechanism 303, and a stopper 304.

In the present embodiment, the feeding unit 3 includes two sets of adjustment mechanisms 301 and two sets of lens carrying mechanisms 302. In the present embodiment, the two sets of lens-carrying mechanisms 302 respectively correspond to the two sets of adjusting mechanisms 301, and also respectively correspond to the two sets of milling mechanisms 103. In the present embodiment, as shown in fig. 3, the driving mechanism 303 is located at the lowermost side, and the adjusting mechanism 301 is supported on the driving mechanism 303, and can be reciprocally linearly moved along a guide rail in the driving mechanism 303 by the driving of the driving mechanism 303. The lens carrier 302 is supported on the adjustment mechanism 301, which is movable simultaneously with the adjustment mechanism 301. In addition, a stopper 304 is provided at one end of the driving mechanism 303, and as shown in fig. 3, the stopper 304 is provided at the rear end of the driving mechanism 303, which is used to limit the movement range of the adjusting mechanism 301 and the lens carrying mechanism 302, so that the movement positions of the adjusting mechanism 301 and the lens carrying mechanism 302 on the driving mechanism 303 can be effectively controlled, the lens in the lens carrying mechanism 302 is ensured to have high in-place rate, and no position error is generated.

As shown in fig. 3, in the present embodiment, the driving mechanism 303 includes a slide rail 3031, a slider 3032, and a cylinder 3033. In this embodiment, the slide 3032 is slidingly coupled to the slide 3031, with the slide 3032 supporting the feed unit 3. The cylinder 3033 is used to drive the feeding unit 3 to perform a reciprocating linear movement, i.e. the feeding unit 3 is moved back and forth on the sliding rail 3031 by means of the sliding block 3032. In the present invention, the driving mechanism 303 may also use a servo motor to drive the ball screw module to move. The arrangement of the driving mechanism ensures high moving precision, and the surface of the milled lens is smoother.

Fig. 4 schematically shows a perspective view of an adjustment mechanism according to an embodiment of the invention. As shown in fig. 4, the adjustment mechanism 301 includes a first support plate 3011, a second support plate 3012, a mounting plate 3013, a first adjuster 3014, and a second adjuster 3015. In the present embodiment, a first support plate 3011 is used to support the lens carrying mechanism 302, a second support plate 3012 is used to support the first support plate 3011, and a mounting plate 3013 is used to support the second support plate 3012. The first adjuster 3014 can adjust the position of the first support plate 3011, and the second adjuster 3015 can adjust the position of the second support plate 3012. According to one embodiment of the invention, the two sets of adjustment mechanisms 301 may share a single mounting plate 3013, although separate mounting plates 3013 may be used. As shown in fig. 4, in the present embodiment, two sets of adjustment mechanisms 301 share a single mounting plate 3013. The material consumption of the material conveying unit 3 can be reduced by the arrangement, so that the structure of the material conveying unit is simple and reasonable, and the structural arrangement is clear and concise.

As shown in fig. 4, the first adjustor 3014 is fixedly installed at a side end position of the second support plate 3012, as in the left side end position of the second support plate 3012 in fig. 4. As shown in fig. 4, the first adjustor 3014 is composed of a first fixing plate 3014a, a first micrometer 3014b, and a first adjusting screw 3014 c. In the present embodiment, the first adjustor 3014 is fixed to the side end of the second support plate 3012 by a first fixing plate 3014 a. The first micrometer 3014b is screwed to the first support plate 3011 through the first fixing plate 3014 a. The first adjustment screw 3014c is also screwed through the first fixing plate 3014a to the first support plate 3011. So configured, the position of the first support plate 3011 can be coarse-tuned by the first adjustment screw 3014c, and then the position of the first support plate 3011 can be fine-tuned by the first micrometer 3014 b. In the present embodiment, the first adjustor 3014 can adjust the position (lateral position) of the first support plate 3011 in the left-right direction in fig. 4.

As shown in fig. 4, the second regulator 3015 is fixedly mounted to a side wall of the mounting plate 3013, such as the front wall of the mounting plate 3013 in fig. 4. As shown in fig. 4, the second adjustor 3015 is composed of a second fixing plate 3015a, a second micrometer 3015b, and a second adjusting screw 3015 c. In the present embodiment, the second adjustor 3015 is fixed to the side wall of the mounting plate 3013 by a second fixing plate 3015 a. The second micrometer 3015b is screwed to the second support plate 3012 through the second fixing plate 3015a, and the second adjustment screw 3015c is also screwed to the second support plate 3012 through the second fixing plate 3015 a. So configured, the position of the second support plate 3012 can be coarsely adjusted by the second adjustment screw 3015c, and then the position of the second support plate 3012 can be finely adjusted by the second micrometer 3015 b. In the present embodiment, the second adjustor 3015 can adjust the position (longitudinal position) of the second support plate 3012 in the front-rear direction in fig. 4. Because the first support plate 3011 is supported on the second support plate 3012, the longitudinal position of the first support plate 3011 is adjusted simultaneously when the longitudinal position of the second support plate 3012 is adjusted by the second adjuster 3015. Therefore, both the lateral position and the longitudinal position of the first support plate 3011 can be precisely adjusted. Because the lens carrying mechanism 302 is supported on the first supporting plate 3011, the lens carrying mechanism 302 can drive the optical lens to freely adjust the position along the transverse direction or the longitudinal direction, so that the position accuracy is high enough to ensure the milling accuracy and the milling efficiency.

As shown in fig. 5, the lens carrier 302 includes a base 3021, a lens support base 3022, a lens cover 3023, a positioning fixture 3024, and an air fitting 3025. In the present embodiment, in combination with the lens carrier mechanism shown in fig. 5 and 6, a ventilation pipe is provided in the base 3021, and the bottom of the lens holder 3022 is mounted with a clearance to the base 3021.

In addition, a positioning jig 3024 for quick-fixing the lens cover plate 3023 and an air fitting 3025 for connecting an external air source are fixedly mounted on the base 3021, and in this embodiment, the positioning jig 3024 employs a quick toggle clamp.

According to the above arrangement, as shown in fig. 5, more specifically: the base 3021 includes a first mount 3021a for mounting on the first support plate 3011. A positioning jig 3024 may be mounted on the upper surface of the first mount 3021a as shown in fig. 5, and an air joint 3025 may be mounted on the left side end surface of the first mount 3021a. The base 3021 further comprises a second mount 3021b for supporting the lens support base 3022. In the present embodiment, the second mount 3021b includes a mount for mounting the lens support base 3022, and a recess 3021 b' corresponding to the ventilation pipe is provided in the mount. By such arrangement, when the lens support base 3022 is mounted on the second mounting base 3021b, a gap (i.e., a groove 3021b ') is formed therebetween, and at this time, the air connector 3025 supplies pressure air through an external air source to blow the pressure air toward the groove 3021b ' through the pipeline, and the lower surface of the optical lens in the lens support base 3022 corresponds to the groove 3021b ', so that the pressure air can blow away milling chips on the lower surface of the optical lens in time, and the cleanliness of the lower surface of the optical lens is ensured. In addition, a ventilation pipeline is formed between the lens cover plate 3023 and the lens supporting seat 3022, and pressure gas is blown to the ventilation pipeline through the air connector 3025 to blow the upper surface of the optical lens, so that the cleanliness of the upper surface of the optical lens is ensured.

Fig. 7 is a development view schematically showing a three-dimensional structural arrangement of the dust collecting unit according to an embodiment of the present invention. As shown in fig. 7, the dust collection unit 2 includes a dust collection box 201, a cover plate 202, and a hopper 203. In the present embodiment, the dust box 201 is made of a transparent material, and the condition of the milling cutter 1031 operating therein and the surface condition of the optical lens during milling can be observed from time to time using the transparent dust box 201. The cover plate 202 is used to cover the dust box 201, and the hopper 203 can drain milling chips collected by the dust box 201 out of the device in time. In this embodiment, the cover plate 202 comprises two through holes 2021 for two milling cutters 1031 of the two sets of milling mechanisms 103 to pass through and into the dust bin 201, respectively.

As shown in fig. 7, the dust box 201 includes a cavity 2011 that can accommodate the milling cutter 1031, and two windows 2012 that are separated and partially inserted by the two sets of lens bearing mechanisms 302 and correspond to the milling cutter. In the present invention, the optical lens is loaded in the lens carrying mechanism 302, a portion of the optical lens having a material shank is exposed, the portion of the optical lens having the material shank is moved to the dust collection box 201 of the dust collection unit 2 by the feeding unit 3, the portion of the optical lens having the material shank is extended from the window 2012 into the dust collection box to below the milling cutter 1031, and then the milling process is performed on the material shank of the optical lens by adjusting and controlling the position of the milling cutter 1031.

According to the milling device for an optical lens of the present invention, the dust box 201 in the dust collecting unit 2 is arranged with a dust blower 2013 for guiding the orderly discharge of milling chips. The air blown by the dust blower 2013 can form an air curtain to prevent milling scraps from flying out of the feed opening (i.e. the window 2012) and falling onto the machine to influence the cleanliness of the machine.
