Description

Technical Field

[0001] The invention relates to the field of spraying technology, in particular to a mechanical spraying device for surface treatment of metal accessories of optical lenses. Background Art

[0002] Optical lens metal accessories spraying device is a device used to spray coating on metal accessories of optical lenses. Optical lens accessories usually need to spray special coatings on their surfaces to provide protection, improve optical performance or achieve other specific needs. Spray coatings can include anti-reflective coatings, anti-scratch coatings, coatings, etc., which are very important for the performance and life of optical lenses and are widely used in the optical lens manufacturing industry:

[0003] Due to improper paint mixing, inappropriate nozzle size or too fast evaporation of the spray liquid, the pressure of the spray paint will be too high or too low, the spray pressure of the spray paint will be unstable, or when spraying the paint, the distance between the spray gun and the object to be sprayed and the spraying angle are not selected correctly. If the distance is too close or too far, or the angle is incorrect, it will cause uneven coating. In the spraying process, some spray devices are sprayed by the operator's hand-held spray device, but the stability of the spray device and the control ability of the spray speed will also affect the uniformity of the spray.

[0045] The complete working principle and steps of the above embodiment are as follows:

[0046] When using:

[0047] Spraying and spreading steps:

[0048] When it is necessary to spray paint on the accessories of the optical lens, the metal accessory plate to be sprayed is first placed on the upper surface of the transport device 106, and transported to the side close to the ventilation device 105. When the metal accessory plate is transported to the bottom of the spray head 104, the metal accessory plate is sprayed with paint through the spray head 104, and then the transportation continues. When it is transported to the bottom of the smearing plate 24, a signal is transmitted to the controller 102 through the position sensor, and a signal is sent by the controller 102 to start the motor 21, and then the first linkage rod 22 is driven to rotate by the motor 21. Since the first linkage rod 22 is far away A rotating shaft 23 is fixedly connected to one end of the motor 21, so the rotating shaft 23 rotates synchronously with the rotation of the first linkage rod 22, and then when the rotating shaft 23 rotates, it drives the fixedly connected extension block 25 to rotate synchronously. Since the side of the extension block 25 away from the rotating shaft 23 is fixedly connected to the movable rod 28 and the movable rod 28 is placed in an inclined state, when the movable rod 28 rotates, it drives the smoothing plate 24 to take the rotating shaft 23 as the center of the circle, and the excess coating sprayed on the accessory plate is pushed to both sides of the accessory plate as the smoothing plate 24 rotates, and falls from both sides of the accessory plate to the lower part of the spray machine box 1 for collection;

[0049] When the movable rod 28 drives the smoothing plate 24 to sweep away the excess spray paint on the surface of the accessory plate, since the rotating shaft 23 is connected to the second linkage rod 27 through the transmission belt, the second linkage rod 27 is driven to rotate synchronously when the rotating shaft 23 rotates, and then since the second linkage rod 27 is fixedly connected to the first cylindrical gear 210, and the first cylindrical gear 210 is continuously meshed with the bevel gear 29 fixedly connected to the circumferential surface of the movable rod 28, when the second linkage rod 27 rotates, the first cylindrical gear 210 is driven to rotate synchronously, and then when the first cylindrical gear 210 rotates, the bevel gear 29 is driven to rotate through the meshing connection, and since the bevel gear 29 is fixed to the circumferential surface of the movable rod 28, the movable rod 28 and the smoothing plate 24 are driven to rotate, and when the excess spray coating on the surface of the accessory plate is cleaned, the sprayed liquid is smoothed on the accessory plate, so that the paint is evenly covered on the surface of the accessory plate;

[0050] Flipping and secondary spraying steps:

[0051] Then, after the metal plate passes through the smoothing mechanical mechanism 2 to smooth the excess spraying liquid on the surface, when the motor 21 drives the first linkage rod 22 to rotate, since the driving wheel 31 is fixedly connected to the circumferential surface of the first linkage rod 22 away from the motor 21, when the first linkage rod 22 rotates, the driving wheel 31 is driven to rotate, and then when the driving wheel 31 rotates, the driven wheel 34 is driven to rotate synchronously through the transmission belt, and then the driven wheel 34 is fixedly connected to the side away from the spray machine box 1 with a cam 35, and the cam 35 is slidably connected in the arc frame 37, and the sliding rod 33 is slidably connected in the rotating column 32, and the rotating column The side of the crossbeam 36 away from the rotating column 32 is rotatably connected to the crossbeam 36, and the side of the crossbeam 36 away from the sliding rod 33 is fixedly connected to the arc frame 37. Therefore, when the cam 35 rotates with the driven wheel 34 to make the arc frame 37 move to the side away from the rotating column 32, and then when the arc frame 37 moves to the side away from the rotating column 32, since the connecting rod 38 is fixedly connected to one side of the arc frame 37, the connecting rod 38 moves synchronously to the side away from the rotating column 32. Since the side of the connecting rod 38 away from the arc frame 37 is fixedly connected to the buffer rod 310, and the telescopic end of the buffer rod 310 is rotatably connected to the second cylindrical gear 31 When the connecting rod 38 moves to the side away from the rotating column 32, the second cylindrical gear 311 and the sliding block 314 are driven to move synchronously. When the sliding block 314 moves to the side away from the rotating column 32, the first limiting frame 313 is pushed to the side of the buffer rod 310 through the special-shaped sliding groove of the second limiting frame 316. Since the rotating rod 312 is fixedly connected to the inside of the first limiting frame 313, when the first limiting frame 313 moves to the side close to the buffer rod 310, the rotating rod 312 is driven to move synchronously, and then the groove of the first limiting frame 313 and the movable latch 315 are engaged, and when the rotating rod 310 is engaged, the first limiting frame 313 is engaged with the movable latch 315. When 312 moves to the side close to the buffer rod 310, the clamping claw of the rotating rod 312 is retracted into the sliding block 314 to clamp the accessory plate, and then moves to the side away from the rotating column 32. When the rotating rod 312 clamps the accessory plate to the side away from the rotating column 32, the second cylindrical gear 311 is engaged with the rack 317 to drive the accessory plate to flip, and then the spraying is continued through the nozzle 104, and then the surface of the accessory plate is cleaned by the smoothing mechanical mechanism 2. The surface of the accessory can be sprayed at one time, reducing the subsequent processing steps and effectively reducing the fatigue of the construction workers.
