For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] A fully automatic optical lens ink coating machine, such as Figure 1-Figure 9 As shown, it includes: a double-track workbench 1 with electric guide rails fixedly installed on both sides of the table top, the double-track workbench 1 is used to be fixedly installed on the production line in the processing room through the installation holes set around it, and the electric guide rails on both sides are connected with a mobile platform 2, and the mobile platform 2 can move laterally under the action of the electric guide rails, and a batch execution unit 3 for batch transfer and inking operations on the lenses 00 is arranged on the mobile platform 2, and the fixed rotating part of the lenses 00 is a fixed rotating mechanism 4 installed in the middle of the double-track workbench 1. The main function of the fixed rotating mechanism 4 is to adsorb and fix the lenses 00 transferred by the batch execution unit 3, and then make the lenses 00 rotate coaxially, and complete inking on the edges of the lenses 00 during the rotation of the lenses 00; wherein the batch execution unit 3 includes the following parts: an electric telescopic rod 31, a downward pressing inking mechanism 32 and a suction cup frame 33, and the electric telescopic rod 31 is symmetrically installed on both sides of the mobile platform 2, according to Figure 3 As shown, the end of the movable rod of the electric telescopic rod 31 provided on the right side of the mobile platform 2 is connected with a downward pressing ink coating mechanism 32, and the downward pressing ink coating mechanism 32 mainly cooperates with the fixed rotating mechanism 4 to complete the ink coating operation on the lens 00; a suction cup frame 33 is fixedly installed at the end of the movable rod of the electric telescopic rod 31 on the left side of the mobile platform 2, and the suction cup frame 33 is mainly composed of a plurality of suction nozzles 34 installed together on a plate, so that multiple lenses 00 can be sucked at the same time, and the suction cup frame 33 and the downward pressing ink coating mechanism 32 are moved up and down under the action of the electric telescopic rod 31;

[0038] Among them, according to Figure 4 and Figure 5As shown, the fixed rotating mechanism 4 includes: a fixed platform 41 fixed at the middle position of the double-track workbench 1, a first electric push block 42 is fixedly installed at the edge position on the right side of the fixed platform 41, and a pull rod 421 is fixedly connected to the moving end of the first electric push block 42, and the pull rod 421 installed on the first electric push block 42 is in a vertical state; empty pipe suction cups 43 are rotatably connected to the fixed platform 41 through bearings 431 at uniform intervals, and the number of empty pipe suction cups 43 corresponds to the number of suction nozzles 34. 3 is plugged with a piston 432. In a normal state, the piston 432 is located at the upper part of the empty tube suction cup 43. After a lens 00 is placed on the empty tube suction cup 43, the downward movement of the piston 432 can form a negative pressure area between the lens 00 and the empty tube suction cup 43, so that the empty tube suction cup 43 can tightly absorb the lens 00 and keep it stable. The piston 432 is moved downward by adopting the following scheme: a plurality of strip holes 433 leading to the inside are evenly opened on the side wall of the empty tube suction cup 43, and the bottom of the piston 432 is along the circumference. The piston 432 is evenly and fixedly connected with a plurality of plug rods 434, which extend from the strip hole 433, and the plug rods 434 can slide up and down within the range of the strip hole 433. A spring 435 is installed at the bottom of the piston 432, and the spring 435 is mainly used to keep the piston 432 at the upper part of the empty tube suction cup 43. By pressing down the plug rod 434, the piston 432 can be moved down, and after the plug rod 434 is released, the piston 432 resets itself. After the piston 432 is reset, the empty tube suction cup 43 is The negative pressure area between the plate 43 and the lens 00 disappears, and the lens 00 can be taken away; wherein, the distance from the head of the piston 432 to the insertion rod 434 shall not be shorter than the length of the strip hole 433. The purpose of this is that if the distance from the head of the piston 432 to the insertion rod 434 is too short, the piston 432 will move to the strip hole 433 area during the process of pressing the piston 432 downward, so that an effective closed environment cannot be formed and ultimately negative pressure cannot be formed, and the lens 00 placed on the empty tube suction cup 43 cannot be adsorbed;A gear ring 44 is fixedly connected to the end of the insertion rod 434, and the gear ring 44 and the empty tube suction cup 43 are kept on the same axis. The gear rings 44 on multiple empty tube suction cups 43 are meshed with each other, so that multiple empty tube suction cups 43 can rotate at the same time, and a support ring 45 is rotatably connected to the gear ring 44. A group of straight ears extending straightly are symmetrically provided on the top of the support ring 45. A synchronous separation and combination positioning splint is slidably connected through the flat ears provided on the support ring 45. The synchronous separation and combination positioning splint mainly includes: a correction plate 46 with semicircular notches evenly opened on one side, the number of semicircular notches corresponds to the number of empty tube suction cups 43, and the two correction plates 46 are symmetrically slidably installed on both sides of the support ring 45 in a manner that the semicircular notches are opposite to each other. On the straight ears on the side, one of the two straightly installed correction plates 46 is slidably connected to the pull rod 421 in the vertical state, and racks 47 are fixedly connected to both sides of the two correction plates 46. The racks 47 on the two correction plates 46 on the same side are meshed through an intermediate gear 48. Vertical through grooves are opened on both sides of the fixed platform 41. The intermediate gear 48 can slide up and down in the through groove on the fixed platform 41 while rotating itself. Through the cooperation of the intermediate gear 48 and the rack 47, after the correction plate 46 on one side moves a fixed distance, the correction plate 46 on the other side also moves a fixed distance accordingly due to the meshing transmission of the rack 47 and the intermediate gear 48;

[0039] Specifically, after the lens 00 is placed on the empty tube suction cup 43 by the suction cup holder 33, in order to prevent the lens 00 from swinging due to not being kept on the same axis as the empty tube suction cup 43 during the rotation process after being adsorbed and fixed, it is necessary to first push the separated correction plates 46 to contact each other through the pull rod 421 by the first electric push block 42, and the semicircular notches on the two correction plates 46 contact the edges of the lens 00, so that the offset lens 00 is corrected to a position coaxial with the empty tube suction cup 43. After the lens 00 is corrected, the downward pressing ink coating mechanism 32 presses the correction plate 46 downward through the electric telescopic rod 31, and The supporting ring 45, the gear ring 44 and the insert rod 434 are also pressed down, and finally the piston 432 is pressed down, and the empty tube suction cup 43 absorbs the lens 00. At this time, the empty tube suction cup 43 can be rotated and the ink coating operation can be started; the empty tube suction cup 43 is rotated by the reduction drive device 49 installed on the fixed platform 41. The reduction drive device 49 is composed of a servo motor and a reducer installed on the servo motor. The output end of the reducer is provided with a cylindrical gear, and the cylindrical gear is meshed with the gear ring 44. The cylindrical gear can make the gear ring 44 still realize meshing transmission during the up and down movement;

[0040] It should be noted that if the hollow tube suction cup 43 is not provided with the piston 432 to pump air, and an ordinary suction cup without holes is used for adsorption, that is, the fixing action of the lens 00 is to directly press the lens 00 downward to make it adsorb on the hollow tube suction cup 43 after the suction cup frame 33 transfers the lens 00 to the hollow tube suction cup 43. Although this can also complete the fixation of the lens 00, when the center of the circle of the lens 00 is subsequently corrected, the suction nozzle 34 on the hollow tube suction cup 43 has a certain elasticity, which will cause the suction nozzle 34 on the hollow tube suction cup 43 to deform adaptively when the synchronous separation and combination positioning clamp plate calibrates the center position of the lens 00. After the synchronous separation and combination positioning clamp plate is separated from the lens 00, the lens 00 returns to its original position again. In fact, the center of the circle of the lens 00 is not corrected.

[0041] Among them, according to Figure 6 and Figure 7 As shown, the downward pressure inking mechanism 32 mainly includes: a downward pressure frame 71 installed at the end of the movable rod of the electric telescopic rod 31, a receiving chamber is provided at the upper part of the downward pressure frame 71, and a plurality of downwardly extending thorns are evenly distributed on both sides of the lower part of the downward pressure frame 71. The thorns can contact the correction plate 46 after the electric telescopic rod 31 is driven downward, and an equal number of slide plates 72 are evenly arranged on the downward pressure frame 71 according to the number of empty tube suction cups 43. The slide plates 72 slide horizontally on the downward pressure frame 71. An ink brush block 73 is fixedly installed at the lower part of the slide plates 72. The ink brush block 73 is made of sponge / cotton cloth / brush. After the lens 00 is stabilized, the slide plates 72 can slide to bring the ink brush block 73 into contact with the edge of the lens 00, and then complete the rotation of the lens 00. The ink coating operation of the lens 00 is completed; in order to keep the ink on the ink brush block 73 sufficient, an ink tank 731 is also hung on the slide frame 72, and the ink tank 731 is connected to the ink brush block 73 through a conduit, so that the ink brush block 73 can be replenished with ink at any time. After the ink in the ink tank 731 is used up, the ink tank 731 can be removed for replenishment, and a series plate 74 that connects multiple slide frames 72 together is arranged in the accommodation chamber of the lower pressing frame 71, and a second electric push block 75 is also fixedly installed in the accommodation chamber, and the moving end of the second electric push block 75 is fixedly connected to the series plate 74. After the series plate 74 is pushed to move under the action of the second electric push block 75, all the slide frames 72 will move together, so that all the ink brush blocks 73 can simultaneously ink all the lenses 00;

[0042] Specifically, according to Figure 2As shown, after the tray 5 with the lens 00 is placed on the left side of the double-track workbench 1, the mobile platform 2 moves to the left above the tray 5, and the suction cup frame 33 is moved down by the electric telescopic rod 31 to suck up the lens 00, and then the mobile platform 2 is transferred to the empty tube suction cup 43. After the lens 00 is gently placed, the suction cup frame 33 is retracted, and the mobile platform 2 is offset to make the downward pressing ink coating mechanism 32 suspended above the correction plate 46. Before the downward pressing ink coating mechanism 32 is pressed down, the first electric push block 42 pushes the correction plate 46 forward, so that the correction plates 46 are closed together to keep the lens 00 and the empty tube suction cup 43 on the same axis. Figure 6 and Figure 7 As shown, the inking mechanism 32 is then moved downward so that the protrusions on the lower pressing frame 71 are pressed on the correction plate 46. During the continuous downward pressing process, the piston 432 moves down to the limit position to allow the empty tube suction cup 43 to absorb the lens 00. After the lens 00 is stabilized, the deceleration drive device 49 drives the gear ring 44 to rotate, thereby rotating the empty tube suction cup 43 and the lens 00. In order not to affect the inking of the lens 00, the pressed correction plates 46 need to be separated from each other. Therefore, a pull rod 421 is required to pull the correction plates 46 apart. In this process, vibrations will be generated between the protrusions and the correction plate 46 due to the movement friction. In order to avoid affecting the lens 00, a roller 711 is rotatably arranged at the end of the protrusion. The roller 711 can effectively avoid friction and reduce the wear of the burrs. After the lens 00 rotates, the second electric push block 75 pushes the series plate 74 with the ink brush block 73 on the slide frame 72 close to the edge of the lens 00, and the inking operation is completed when the lens 00 rotates. After the inking is completed, the ink brush block 73 is moved away, and then the inking mechanism 32 is pressed down and moved up as a whole to separate from the correction plate 46. Then, the suction cup frame 33 is used to move the inked lens 00 to the storage area on the right side of the double-track workbench 1, and the inked lens 00 is collected. In the above manner, batch inking of the lenses 00 is achieved, the rotation stability of each lens 00 during the inking process is guaranteed, and the processing efficiency is effectively improved.

[0043] In one preferred embodiment, Figure 2 and Figure 8As shown, in order to facilitate the processing of the lens 00, the tray 5 for mounting the lens 00 is improved. The tray 5 is mainly placed on the right side of the double-track workbench 1 for mounting the lens 00. The tray 5 mainly includes: a chassis frame 51 with raised protrusions around the bottom, the raised protrusions can facilitate the chassis frame 51 to be picked up, and a separation groove is provided on the upper surface of the chassis frame 51. The purpose of setting the separation groove is to guide the lens 00 to slide in a fixed area. The placement groove frame 52 is slidably embedded in the separation groove on the chassis frame 51. The placement holes are arranged in a matrix on the placement groove frame 52. The placement holes are aligned with the separation grooves. The lens 00 completed from the previous process is placed in the placement hole. After the placement groove frame 52 is removed, the lens 00 is located in the separation groove on the chassis frame 51. In order to ensure that the placement slot frame 52 and the chassis frame 51 will not slip off easily during use, movable buckle plates 53 are symmetrically hinged on both sides of the chassis frame 51, and a protrusion 54 is provided on the movable buckle plate 53. Normally, when the lenses 00 are placed, the movable buckle plate 53 is adsorbed on the side wall of the placement slot frame 52 by setting a magnetic block 531, and the edge of the placement slot frame 52 is hooked by the protrusion 54, so that the placement slot frame 52 and the chassis frame 51 will not be separated during the transfer of the lenses 00. When feeding is needed, the movable buckle plate 53 can be pried open to remove the placement slot frame 52, so as to achieve the purpose of fast and convenient feeding, and at the same time, damage to the lenses 00 can also be avoided. When the number of lenses 00 to be inked is large, the tray 5 can be pre-stored in the storage bin 8 opened on the side wall of the double-track workbench 1.

[0044] In one preferred embodiment, Figure 2 and Fig. 9As shown, in order to reduce the number of manual feeding times of the lenses 00, a large number of lenses 00 can be stored by fixing the inclined feeding rack 6 on the left side of the double-track workbench 1 to cooperate with the batch execution unit 3 to complete the feeding; the inclined feeding rack 6 mainly includes: an inclined plate 61 fixedly set on the left side of the double-track workbench 1, a notch is opened in the middle of the inclined plate 61, a plurality of rotating rods 62 are evenly connected in the horizontal direction and rotated in the notch, and a plurality of dividing strips 63 are evenly fixedly connected to the inclined plate 61 in the longitudinal direction, and the dividing strips 63 and the rotating rods 62 are mutually connected. The dividing strip 63 divides the inclined plate 61 into a plurality of guide slides of the same width as the dividing grooves. After the tray 5 takes away the placing groove frame 52, the lens 00 in the dividing groove can be laid in the inclined guide slide. Whenever the lens 00 at the lower part of the inclined plate 61 is taken away, the upper lens 00 slides downward. At the lower part of the inclined plate 61, an arc-shaped limiting block 65 is provided at the end of the guiding slide. The arc-shaped limiting block 65 is mainly used to keep the lens 00 at the end of the guiding slide in a fixed central position, so that In order to prevent the suction cup frame 33 from having a large position deviation when adsorbing the lens 00, a supporting plate 66 is fixedly installed at the upper position of the inclined plate 61. The supporting plate 66 allows the chassis frame 51 to be placed on it, so that the lens 00 on the chassis frame 51 can slide into the guide slide better. By storing a large number of lenses 00 in the guide slide, the number of manual regular feedings can be effectively reduced. In order to prevent the lenses 00 in the guide slide from arching, a limiting pressure plate 64 is fixedly installed on the dividing strip 63 to form a closed guide slide. It should be noted that in order to prevent the lenses 00 from colliding with the inclined plate 61 due to excessive inertia during the process of sliding down the guide slide, or colliding with each other, some flexible obstructing materials, such as flexible bristles or elastic blocking plates, can be appropriately added on both sides of the guide slide to hinder the sliding speed of the lenses 00, and in the guide slide, the surface of the components on the side in contact with the lenses 00 can be paved with flexible wool pads to prevent the lenses 00 from being scratched during the sliding process.

[0045] In one preferred embodiment, Figure 5 As shown, since common suction nozzles 34 are all capable of elastic deformation, in order to prevent the suction nozzle 34 from being slightly deformed after the hollow tube suction cup 43 adsorbs the lens 00, which in turn causes uneven ink coating during the ink coating process of the lens 00, a stabilizing ring 410 is fixedly sleeved on the hollow tube suction cup 43. The stabilizing ring 410 is flush with the top of the hollow tube suction cup 43, and the lens 00 is supported from the bottom by the stabilizing ring 410. In this way, even if the suction nozzle 34 is deformed, the lens 00 will still remain in a fixed position under the action of the stabilizing ring 410.

[0046] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
