Description

Technical Field

[0001] This utility model relates to the field of optical element processing technology, and in particular to a device for removing liquid accumulated on a dome. Background Technology

[0002] PC (polycarbonate) is a high-strength, high-transparency engineering plastic widely used in eyeglass lenses, mobile phone screens, automotive headlight covers, bulletproof glass, etc. However, PC has a relatively low surface hardness (Mohs hardness of about 3-4), making it easy to scratch. Therefore, PC hardening liquid (also known as PC hardening liquid or PC hardening coating) is often used to improve its surface hardness (up to 6-9H pencil hardness).

[0003] In the hardening process of PC dome, the hardening liquid is prone to local accumulation on the surface of the dome. If the accumulated liquid is not removed in time, it will have multiple negative impacts on product performance and production efficiency: (1) Uneven thickness: After the accumulated area is cured, it forms a protrusion, which leads to inconsistent light transmittance or refractive index of the dome, affecting optical uniformity (such as lens imaging distortion). (2) Surface defects: After the accumulated liquid is cured, it may produce ripples, orange peel or bubbles, reducing the surface smoothness. (3) Stress concentration: Locally excessively thick hardened layers may cause microcracks due to differences in internal stress, reducing the impact resistance of the dome. (4) Adhesion problems: When the accumulated area is not thoroughly cured, the coating is easy to peel off, affecting wear resistance. Utility Model Content

[0004] The purpose of this invention is to provide a suction device for removing liquid accumulated on a dome, which can remove the accumulated liquid.

[0005] The technical solution of this utility model:

A base plate is provided on the top of the frame, and a chemical tank is fixed on the base plate. A rotating seat for placing the spherical dome is provided in the chemical tank. The rotating seat is driven by a rotating component. The rotating component drives the rotating seat to rotate, thereby causing the spherical dome to rotate. At the same time, the spray pipe sprays hardening liquid onto the spherical dome from above, and the suction pipe suctions away the accumulated liquid at the lower end of the outer wall of the spherical dome.

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] like Figures 1-9As shown, this utility model provides a first embodiment of a suction device for removing liquid accumulated on a spherical cover, including a suction pipe 1 and a spray pipe 2. The suction pipe 1 is connected to a negative pressure generator, and the spray pipe 2 is connected to a spray water pump in a cooling constant temperature chamber for the hardening liquid. It also includes a frame 3, with a base plate 4 on top of the frame 3. A chemical tank 5 is fixed on the base plate 4 for collecting the hardening liquid flowing downwards from the spherical cover 100. A rotating seat 6 for placing the spherical cover 100 is provided in the chemical tank 5. The rotating seat 6 is driven by a rotating assembly; the rotating assembly drives the rotating seat 6 to rotate, thereby causing the spherical cover 100 to rotate. Simultaneously, the spray pipe 2 sprays the hardening liquid onto the spherical cover 100 from above, and the suction pipe 1 suctions the accumulated liquid from the lower end of the outer wall of the spherical cover 100.

[0034] The rotating base 6 is equipped with a limiting component for limiting the ball cover 100. The limiting component includes fixing blocks 81 fixed at both ends of the rotating base 6. A limiting cylinder 82 is fixed on the fixing blocks 81. The limiting cylinder 82 can be a threaded cylinder of model MPE6x5, but is not limited to this. The push rod of the limiting cylinder 82 is fixed with a positioning block 84. A limiting pin 85 is fixed on the positioning block 84. The ball cover 100 has a limiting hole 200 for the insertion of the limiting pin 85. The ball cover 100 is placed on the rotating base 6, so that the limiting hole 200 is aligned with the limiting pin 85. The limiting cylinder 82 drives the positioning block 84 to move outward, thereby driving the limiting pin 85 to move outward and insert into the limiting hole 200, thus completing the limiting of the ball cover 100.

[0035] The rotating assembly includes a hollow rotating platform 71 fixed in the mounting slot 51 within the medicine tank 5. The hollow rotating platform 71 is driven by a first motor 72. The rotating end of the hollow rotating platform 71 is connected to the bottom of the rotating seat 6 via a mounting plate 73. The first motor 72 drives the rotating end of the hollow rotating platform 71 to rotate, thereby causing the mounting plate 73 to rotate, which in turn causes the rotating seat 6 to rotate, and consequently, the spherical cover 100 to rotate.

[0036] Based on the first embodiment, this utility model provides a second embodiment of a suction device for accumulating liquid on a spherical cover. The rotating seat 6 is also fixed with a guide plate 87. The guide plate 87 has a guide hole for the limit pin 85 to pass through. By cooperating with the guide hole, the limit pin 85 can play a limiting and guiding role during the movement of the limit pin 85.

[0037] Based on any of the above embodiments, this utility model provides a third embodiment of a suction device for accumulating liquid on a spherical cover. The rotating seat 6 is also provided with a cover plate 9, which is connected to the rotating seat 6 by bolts. When the spherical cover 100 is placed on the rotating seat 6, the cover plate 9 is wrapped inside the spherical cover 100. The cover plate 9 can prevent the hardening liquid from flowing from the gap of the rotating seat 6 into the hollow rotating platform 71.

[0038] Based on any of the above embodiments, this utility model provides a fourth embodiment of a suction device for removing liquid accumulated on a spherical cover. The spray pipe 2 is driven by a first moving component, which can adjust the position of the spray pipe 2 so that it can be moved above the spherical cover 100 for spraying. The first moving component includes a first base 21, which is fixed on the left side of the medicine tank 5 on the base plate 4. A first ball screw 22 is provided on the first base 21, which is driven by a first turntable 23. A slide cylinder 24 is fixed on the slider of the first ball screw 22. The slide cylinder 24 can be of model HLQ12X50, but is not limited to this. The spray pipe 2 is connected to the slide of the slide cylinder 24 via a first connecting plate 25.

[0039] Rotating the first turntable 23 drives the first ball screw 22 to rotate, which in turn drives the slide cylinder 24 to move up and down, thereby driving the spray pipe 2 to move up and down and adjusting the height of the spray pipe 2; the slide cylinder 24 drives the first connecting plate 25 to move left and right, which in turn drives the spray pipe 2 to move left and right and adjusts the horizontal position of the spray pipe 2.

[0040] Based on the fourth embodiment, this utility model provides a fifth embodiment of a suction device for removing liquid accumulated on a spherical cover. The suction tube 1 is driven by a second moving component, which can adjust the position of the suction tube 1 so that it can be moved to the lower end of the outer wall of the spherical cover 100 to remove the accumulated liquid. The second moving component includes an electric slide table 101, which is fixed on the right side of the medicine tank 5 on the base plate 4. A second base 102 is fixed on the slide table 101, and a second ball screw 103 is provided on the second base 102. The second ball screw 103 is driven by a second turntable 104. The suction tube 1 is connected to the slider of the second ball screw 103 via a second connecting plate 105.

[0041] The electric slide 101 drives the second base 102 to move left and right, which in turn drives the second connecting plate 105 to move left and right, thereby driving the suction tube 1 to move left and right and adjusting the horizontal position of the suction tube 1. Rotating the second turntable 104 drives the second ball screw 103 to rotate, which in turn drives the second connecting plate 105 to move up and down, thereby driving the suction tube 1 to move up and down and adjusting the height of the suction tube 1.

[0042] Based on the fifth embodiment, this utility model provides a sixth embodiment of a suction device for accumulating liquid on a spherical cover. A laser rangefinder 106 is also fixed on the second connecting plate 105. The laser rangefinder 106 can be of model blg-30nm, but is not limited to this. In actual production, the spherical cover 100 has a certain deviation in roundness, causing the distance between the lower end of its outer wall and the suction pipe 1 to change continuously during rotation, thus affecting the suction effect. The laser rangefinder 106 can provide feedback on the distance between the suction pipe 1 and the lower end of the outer wall of the spherical cover 100. The distance between the suction pipe 1 and the lower end of the outer wall of the spherical cover 100 can then be adjusted by the electric slide 101, resulting in better suction of the accumulated liquid.

[0043] Based on the fifth or sixth embodiment, this utility model provides a seventh embodiment of a suction device for accumulating liquid on a spherical cover. The spray pipe 2 is fixed to the first connecting plate 25 by the first support block 26. The first connecting plate 25 has a first arc-shaped groove 27. One end of the first support block 26 is hinged to the first connecting plate 25, and the other end is fixed to the first arc-shaped groove 27 by bolts and nuts. When it is necessary to adjust the angle of the spray pipe 2, the nut is loosened, and the first support block 26 is rotated around the hinge point to adjust the angle of the spray pipe 2. After the angle is adjusted, the nut is tightened to complete the adjustment.

[0044] The suction tube 1 is fixed to the second connecting plate 105 via the second support block 107. The second connecting plate 105 has a second arc-shaped groove 108. One end of the second support block 107 is hinged to the second connecting plate 105, and the other end is fixed to the second arc-shaped groove 108 by bolts and nuts. This allows the angle of the suction tube 1 to be adjusted by loosening the nut and rotating the second support block 107 around the hinge point. After adjusting the angle, the nut is tightened to complete the adjustment.

[0045] Based on any of the above embodiments, this utility model provides an eighth embodiment of a suction device for removing liquid accumulated on a ball cover 100. The right end of the base plate 4 is connected to the top of the frame 3 via a hinge 10; a self-aligning rotating assembly is hinged to the left end of the frame 3; a third ball screw 12 is connected to the self-aligning rotating assembly, and the third ball screw 12 is driven by a handwheel 13; the slider of the third ball screw 12 is hinged to the left end of the base plate 4. By rotating the handwheel 13, the third ball screw 12 is rotated, thereby causing the slider of the third ball screw 12 to move up and down, thereby causing the base plate 4 to rotate around the hinge 10, so that the base plate 4 can be tilted, which facilitates the flow of hardening liquid to the right end of the ball cover 100, so that most of the accumulated liquid accumulates at the lower end of the right outer wall of the ball cover 100, and can be better removed by the suction pipe 1.

[0046] The adjusting rotation assembly includes a self-aligning ball bearing 11 hinged to the frame 3, and a third ball screw 12 is connected to the inner shaft of the self-aligning ball bearing 11. In practical applications, the weight of the base plate 4 will accumulate on the third ball screw 12, causing the third ball screw 12 to have a downward force. Therefore, the self-aligning rotation assembly hinged to the frame 3 will rotate downward around the hinge point. The self-aligning ball bearing 11 allows the inner shaft of the self-aligning ball bearing 11 to tilt and form an angle with the outer shaft after rotating downward around the hinge point, and the inner shaft can also rotate, which facilitates the rotation of the third ball screw 12.

[0047] Alternatively, the self-aligning rotating assembly includes a spherical bearing hinged to the frame 3. A conventional bearing is fixed on the inner shaft of the spherical bearing, and a third ball screw 12 is connected to the conventional bearing. In practical applications, the weight of the base plate 4 will accumulate on the third ball screw 12, causing it to exert a downward force. Therefore, the self-aligning rotating assembly hinged to the frame 3 will rotate downward around the hinge point. The spherical bearing allows the inner shaft of the spherical bearing to tilt and form an angle with the outer shaft after rotating downward around the hinge point. Furthermore, since a conventional bearing is fixed on the inner shaft, it can rotate relative to the inner shaft of the spherical bearing, facilitating the rotation of the third ball screw 12.

[0048] The negative pressure generator, the enhanced liquid cooling constant temperature chamber, the hollow rotating platform, the ball screw, the electric slide, the spherical bearing, and the self-aligning ball bearing in this utility model are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0049] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
