When the sand blasting machine is used, after sand blasting is finished, the air pump 7 is started, the air pump 7 sprays air to the air spraying pipe 56 through the air pipe, the air spraying pipe 56 sprays air to the top end of the boss 2, the cleaning degree of the boss 2 is increased, sand grains are prevented from remaining on the top end of the boss 2 when the next sand blasting treatment is carried out, and the lens is prevented from being worn on the lens placement boss 2, so that the lens is damaged; by arranging the group of air ejector tubes 56 fixedly connected between the two first shafts 25, when the air ejector tubes 56 jet air towards the top end of the boss 2, the air flow direction is consistent, sand grains remained at the top end of the boss 2 are blown away, the cleaning degree of the top end of the boss 2 is further increased, the situation that when the air ejector tubes 56 jet air towards the top end of the boss 2, the air flow direction is opposite, an air flow cluster is formed at the top end of the boss 2, air is accumulated at the top end of the boss 2, and the possibility that the sand grains at the top end of the boss 2 are not cleaned cleanly is caused; through setting up filter screen 57 for when jet-propelled pipe 56 jet-propelled to boss 2 top, filter from air pump 7 spun air, increase the clean degree on boss 2 top, prevent boss 2 from receiving the dust influence in the air, lead to boss 2 top secondary pollution.
As an embodiment of the present invention, a contact timer 55 is fixedly connected to the boss 2 near the outer surface of the ring 51, and the timer 55 is electrically connected to the air pump 7; the surface of the outer ring of the circular ring 51 is fixedly connected with a poking rod 54, and the air injection of the air injection pipe 56 to the round table 11 is realized through the cooperation between the poking rod 54 and the timer 55 when the motor 6 stops rotating.
When the novel air pump is used, the ring 51 drives the poking rod 54 to move, when the motor 6 stops reversing, the poking rod 54 contacts with the timer 55, the timer 55 starts to drive the air pump 7 to jet air to the air ejector tube 56, the air ejector tube 56 jets air to the top end of the boss 2, when the set time of the timer 55 arrives, the timer 55 stops, the air pump 7 stops jetting air to the air ejector tube 56, a worker places a next lens to be subjected to sand blasting on the boss 2, the air pump 7 jets air automatically through cooperation among the timer 55, the air pump 7 and the poking rod 54, the top end of the boss 2 is cleaned, workload of the worker is reduced, the work efficiency of the worker is increased, and the production efficiency is increased.
The specific working procedure is as follows:
after the coating treatment of the part of the lens which does not need sand blasting treatment, the lens is placed on the boss 2, the vacuum chuck 22 is started by the controller, the lens is adsorbed on the top end of the boss 2 by the vacuum chuck 22, the motor 6 is started, when the motor 6 rotates positively, the output shaft of the motor 6 rotates to drive the circular ring 51 to rotate, the circular ring 51 drives the rotating rod 4 to rotate, the rotating rod 4 drives the push rod 3 to move towards the direction close to the lens, the push rod 3 drives the clamping plate 31 to clamp the lens, and when the clamping plate 31 contacts the lens; after the lens is contacted by the clamping plate 31 through the matching between the boss 2 and the first blind hole 12, the clamping plate 31 drives the lens to move towards the center of the round table 11, and as the lens is adsorbed on the top end of the boss 2 by the vacuum chuck 22, the lens drives the boss 2 to move towards the center of the round table 11 in the first blind hole 12, so that the stability of the lens is improved; the clamping plate 31 contacts the edge of the lens towards the arc-shaped outer surface of the lens to clamp the lens, and the acting force of the clamping plate 31 on the edge in the lens is the clamping force towards the center of the boss 2 and the downward extrusion force of the edge of the lens; the clamping plate 31 drives the plastic plate 32 to move, and the plastic plate 32 bends towards the clamping plate 31 after contacting the edge of the lens until the bending part in the plastic plate 32 contacts the arc-shaped surface of the clamping plate 31, so that the contact between the clamping plate 31 and the lens is reduced when the clamping plate 31 clamps the lens by contacting the edge of the lens; due to the arrangement of the plastic plate 32, one part of the plastic plate 32 is bent after contacting the edge of the lens until contacting the arc-shaped surface of the clamping plate 31, the plastic plate 32 drives the lens and the boss 2 to move towards the center of the round table 11, the other part of the plastic plate 32 which is not contacted with the lens contacts the edge of the lens in the moving process, and the other part of the plastic plate 32 is bent, so that the clamping plate 31 has a damping effect when clamping the lens; when the three plastic plates 32 contact the edge of the lens and then bend to contact the arc-shaped surface of the clamping plate 31, the three plastic plates 32 contact the outer surface of the clamping plate 31 and are continuously attached to the surface of the clamping plate 31 under the action of the clamping plate 31 until contacting the contact in the first limit switch 34, the three first limit switches 34 are started to stop the motor 6 from rotating positively, and when lenses with different sizes are processed, compared with the prior art, the clamping size is required to be readjusted and a worker needs to observe and judge whether the lens is clamped or not, and by arranging the three first limit switches 34, the motor 6 automatically stops after the lens is clamped, so that the working process of the worker is reduced, and the working efficiency of the worker is increased; after the sand blasting is finished, the motor 6 is started to rotate reversely, the output shaft of the motor 6 drives the circular ring 51 to rotate, the circular ring 51 drives the rotating shaft to rotate, the rotating shaft drives the push rod 3 to move away from the boss 2 until a second limit switch 53 on the push rod 3 contacts a first shaft 25, the second limit switch 53 is started, and the motor 6 stops rotating reversely; the ring 51 drives the poking rod 54 motion, when motor 6 stops reversing, poking rod 54 contacts time-recorder 55, time-recorder 55 starts to drive air pump 7 to jet tube 56 timing jet, jet tube 56 is clean to boss 2 top jet, when time-recorder 55 settlement time arrives, time-recorder 55 stops, drive air pump 7 stop jet to jet tube 56 jet, the staff places the lens of treating sand blasting on boss 2 next, cooperation between through time-recorder 55, air pump 7 and poking rod 54, make air pump 7 jet automatically, clean boss 2 top, reduce staff's work load, thereby increase staff's work efficiency, and then increase production efficiency.
