Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a plastic lens coating machine. Background Art

[0002] Lens coating machine refers to the process of coating a layer of metal film on the surface of optical lens, so that the optical lens can reduce or increase the reflection, beam splitting, color separation, filtering, polarization and other requirements of light. It is a common facility for the production and processing of optical lenses and is widely used in lens manufacturers. As the number of glasses used by people has been increasing, the demand for lenses has increased, making lens coating machines gradually unable to meet the current processing and use. More convenient lens coating machines are needed for processing and production. Since the lens has a certain curvature, during the coating process from the inside to the outside of the lens, there will be a certain height difference between the inside and outside of the lens, which will cause the coating head to be unable to perform all-round sputtering on the curved lens, resulting in poor uniformity of the mirror coating.

The utility model is further explained below in conjunction with the specific implementation mode. Example

[0020] like Figure 1-Figure 5 As shown, the utility model provides a plastic lens coating machine, which structure includes a driving motor 3, a visual window 1, a main unit 2, an indicator light 4, and a base 5. The driving motor 3, the indicator light 4 and the main unit 2 are matched in an electrically connected manner. The main unit 2 is fixedly connected to the visual window 1 on the outside, and the bottom of the main unit 2 is welded and connected to the top of the base 5;

[0021] The host 2 includes a body 2q, a coating nozzle 2w, a connecting rod 2e, a built-in clamp 2r, and a positioning seat 2t. The coating nozzle 2w and the positioning seat 2t are fixedly connected inside the body 2q through the connecting rod 2e. The coating nozzle 2w is loosely fitted above the positioning seat 2t. The built-in clamp 2r is installed inside the positioning seat 2t.

[0022] The built-in card component 2r includes a partition r1, a built-in cover r5, a lifting structure r2, a connecting shaft r3, and a mounting groove r4. The partition r1 is fixedly connected between the built-in cover r5 and the mounting groove r4. The mounting groove r4 is sleeve-connected to the inside of the positioning seat 2t, and the lifting structure r2 is installed inside the mounting groove r4 through the connecting shaft r3.

[0023] The built-in cover r5 is a circular folding structure, which is movably engaged inside the partition r1 through the lifting structure r2, and the middle part of the built-in cover r5 is interference-fitted with the outside of the coating nozzle 2w, and can be opened from the inside to the outside and expanded under the lens due to the spraying direction of the coating nozzle 2w.

[0024] The lifting structure r2 includes a support plate r22, a docking sleeve r23, a correction handle r24, a protruding piece r21, and an arch strip r25. The tip of the support plate r22 is fixedly connected to the docking sleeve r23, and the support plate r22 is slidably fitted on the built-in cover r5 and the bottom of the partition r1 through the protruding piece r21. The docking sleeve r23 is sleeved on the tip of the correction handle r24. The end of the correction handle r24 is hingedly connected to the inside of the installation groove r4 through the connecting shaft r3, and the arch strip r25 is welded between the correction handles r24.

[0025] The arch strip r25 is interference-fitted in the installation groove r4 through the correction handle r24, and has a certain elasticity, and its bending degree is determined by the swing angle of the correction handle r24.

[0026] The protruding piece r21 includes a top plate 21a, a cross buckle 21s, a vertical side strip 21d, and a telescopic rod 21f. The top plate 21a is hingedly connected between the support plates r22, and the vertical side strip 21d is fixedly connected at the intersection of the top plate 21a. The vertical side strip 21d is internally welded with a cross buckle 21s and a telescopic rod 21f. The cross buckle 21s is interference fit at the bottom of the built-in cover r5.

[0027] Based on the above embodiment, the specific working principle is as follows:

[0028] The driving motor 3 is used to control the coating nozzle 2w under the connecting rod 2e inside the machine body 2q to coat the lens inside the positioning seat 2t from the inside out. As the coating nozzle 2w sprays, the lens will be pressed against the upper part of the built-in cover r5, so that the built-in cover r5 will release the pressure on the support plate r22 along the spraying direction, so that the arch strip r25 between the pointing handle r24 on the back of the support plate r22 will rebound and stretch, and the arch strip r25 will shorten, and then the pointing handle r24 will be involved to drive the support plate r22 to expand outward and swing at the bottom of the built-in cover r5. The top plate 21a in between drives the cross buckle 21s and the telescopic rod 21f to tilt close to the bottom of the built-in cover r5, allowing the cross buckle 21s to leverage the opening of the top plate 21a and the telescopic rod 21f, and cooperate with the tip of the support plate r22 to support and lift the middle of the built-in cover r5, so that the built-in cover r5 bulges upward, and the outer edge is tightly held to lift the edge of the lens close to the coating nozzle 2w, adjusting the height difference between the coating nozzle 2w, which is beneficial for the coating nozzle 2w to perform all-round sputtering on the curved lens, ensuring the uniformity of the mirror coating.
