Description

Technical Field

[0001] This application relates to the field of optical lens processing technology, specifically to an optical lens pressing and coating device. Background Technology

[0002] Utility model patent CN219256473U discloses an automatic glass lens coating device, including a frame with several conveying rollers rotatably mounted on it. Glass lenses are conveyed on these rollers. First support seats are also mounted opposite each other on the frame. Bearing seats are mounted on the tops of the two first support seats, and a material roller is rotatably mounted between the bearing seats. A protective film roll is mounted on the material roller, with its free end extending between a pressure roller and the glass lens. The pressure roller is movably mounted on a second support seat via a drive cylinder. The second support seat is mounted opposite to the frame. This utility model solves the problem that current methods for applying protective films to glass lens surfaces mainly rely on manual application. Manual application is prone to misalignment, air bubbles, poor bonding effect, and low efficiency. However, this device has certain shortcomings in use. It is not convenient for clamping and limiting glass of different widths, and air bubbles can remain during the bonding process between the glass and the film, with inefficient and incomplete removal. Utility Model Content

[0003] The purpose of this invention is to provide an optical lens pressing and coating device, which solves the problems that the device is not convenient for clamping and limiting glass of different widths, and that air bubbles exist when the glass and film are bonded together, and the removal of air bubbles is not efficient and complete.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an optical lens pressing and coating device, comprising a frame, a conveying roller disposed inside the frame, a limiting mechanism disposed on the frame, a bracket fixedly connected to the upper end of the frame, a pressing mechanism disposed on the bracket, a mounting frame disposed on the pressing mechanism, the mounting frame and the bracket being slidably connected, and a pressure roller disposed on the mounting frame.

[0005] Preferably, the limiting mechanism includes a support plate, which is fixedly connected to the lower end of the frame. A motor is fixedly mounted on the surface of the support plate, and the motor's shaft passes through and is rotatably connected to the support plate. A bidirectional screw is fixedly connected to the end of the motor's shaft, and the bidirectional screw is rotatably connected to the support plate. A pressure plate is threadedly connected to the outer side of the bidirectional screw. A sliding plate is slidably connected inside the frame, and a guide rod is slidably connected inside the sliding plate. The guide rod is fixedly connected to the pressure plate, and a compression spring is provided on the outer side of the guide rod. A guide roller is provided on the sliding plate. By driving the bidirectional screw to rotate and the pressure plate to perform threaded movement, the compression spring compresses the sliding plate, thereby causing the guide roller to move. This can limit the movement of glass of different widths and prevent positional deviation during the processing of the device.

[0006] Preferably, one end of the compression spring is fixedly connected to the pressure plate, and the other end of the compression spring is fixedly connected to the slide plate. By setting the compression spring, the slide plate is elastically compressed.

[0007] Preferably, the extrusion mechanism includes a screw, which is mounted inside the bracket via bearings. A screw cylinder is threadedly connected to the outside of the screw, and a slide cylinder is slidably connected to the outside of the screw cylinder. A hanger is fixedly connected to the lower end of the slide cylinder, and the hanger is fixedly connected to the mounting bracket. A spring is installed inside the slide cylinder, and a scraper is slidably connected inside the hanger. A motor is fixedly mounted to the upper end of the hanger, and an eccentric wheel is fixedly connected to the upper end of the motor's output. By rotating the screw and screw cylinder to perform threaded motion, the screw cylinder is moved by the spring pressing the mounting bracket, thus ensuring that the pressure roller and scraper remain in contact with the film. Furthermore, the eccentric wheel, driven by the motor, rotates and collides with the baffle, causing the scraper to move back and forth, resulting in more efficient and complete removal of air bubbles between the film and the glass.

[0008] Preferably, a sliding pin is fixedly connected to the surface of the screw cylinder, and the sliding pin and the slide cylinder are slidably connected. By providing the sliding pin, relative rotation between the screw cylinder and the slide cylinder is prevented.

[0009] Preferably, a baffle is fixedly connected to the upper end of the scraper, and the baffle is slidably connected to the hanger. The movement of the scraper is controlled by setting the baffle.

[0010] Preferably, one end of the spring is fixedly connected to the screw cylinder, and the other end of the spring is fixedly connected to the hanger. By setting the spring, the hanger is elastically compressed downwards.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a motor to drive a bidirectional screw to rotate and a pressure plate to make a threaded motion, which in turn causes a pressure spring to squeeze a sliding plate, thereby causing the guide roller to move. This can limit the movement of glass of different widths and prevent positional deviation during the processing of the device.

[0013] 2. This utility model uses the rotating screw and screw barrel to make a spiral motion, which causes the screw barrel to move by the spring pressing the mounting bracket. This allows the pressure roller and scraper to always maintain contact with the film. Furthermore, the eccentric wheel is driven by the motor to rotate and collide with the baffle, which causes the scraper to move back and forth, making the removal of air bubbles between the film and the glass more efficient and complete.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-2 An optical lens pressing and coating device includes a frame 1, a conveying roller 2 inside the frame 1, a limiting mechanism 3 on the frame 1, a bracket 4 fixedly connected to the upper end of the frame 1, a pressing mechanism 5 on the bracket 4, a mounting frame 6 on the pressing mechanism 5, the mounting frame 6 and the bracket 4 being slidably connected, and a pressure roller 7 on the mounting frame 6.

[0021] Please see Figures 1-2The limiting mechanism 3 includes a support plate 31. The lower end of the frame 1 is fixedly connected to the support plate 31. A motor 32 is fixedly mounted on the surface of the support plate 31. The rotating shaft of the motor 32 passes through the support plate 31 and is rotatably connected to the support plate 31. A bidirectional screw 33 is fixedly connected to the end of the rotating shaft of the motor 32. The bidirectional screw 33 is rotatably connected to the support plate 31. A pressure plate 34 is threadedly connected to the outer side of the bidirectional screw 33. A sliding plate 35 is slidably connected inside the frame 1. A guide rod 36 is slidably connected inside the sliding plate 35. The guide rod 36 and the pressure plate are connected to each other. The guide rod 36 is fixedly connected to the pressure plate 34. A compression spring 37 is provided on the outside of the guide rod 36. One end of the compression spring 37 is fixedly connected to the pressure plate 34, and the other end of the compression spring 37 is fixedly connected to the slide plate 35. By setting the compression spring 37, the slide plate 35 is elastically compressed. A guide roller 38 is provided on the slide plate 35. The motor 32 drives the bidirectional screw 33 to rotate and the pressure plate 34 to make a threaded movement, thereby causing the compression spring 37 to compress the slide plate 35, and thus causing the guide roller 38 to move. This can limit the movement of glass with different widths and prevent positional deviation during the processing of the device.

[0022] Please see Figures 1-2 The extrusion mechanism 5 includes a screw 51. The screw 51 is mounted inside the support 4 via bearings. A screw cylinder 52 is threadedly connected to the outside of the screw 51. A slide cylinder 53 is slidably connected to the outside of the screw cylinder 52. A sliding pin 54 is fixedly connected to the surface of the screw cylinder 52, and the sliding pin 54 and slide cylinder 53 are slidably connected. By setting the sliding pin 54, relative rotation between the screw cylinder 52 and slide cylinder 53 is prevented. A hanger 55 is fixedly connected to the lower end of the slide cylinder 53, and the hanger 55 is fixedly connected to the mounting bracket 6. A spring 56 is installed inside the slide cylinder 53. One end of the spring 56 is fixedly connected to the screw cylinder 52, and the other end of the spring 56 is fixedly connected to the hanger 55. By setting the spring 56, the hanger 55 is elastically pressed down. An internal sliding connection is provided with a scraper 57, and a baffle 58 is fixedly connected to the upper end of the scraper 57. The baffle 58 and the hanger 55 are slidably connected. The movement of the scraper 57 is controlled by setting the baffle 58. A motor 59 is fixedly installed at the upper end of the hanger 55. An eccentric wheel 510 is fixedly connected to the upper end of the output end of the motor 59. By rotating the screw 51 and the screw barrel 52 to make threaded movement, the screw barrel 52 is pressed by the spring 56 to move the mounting bracket 6. This allows the pressure roller 7 and the scraper 57 to always maintain contact with the film. The eccentric wheel 510 is driven to rotate by the motor 59 and collide with the baffle 58, thereby causing the scraper 57 to move back and forth, making the removal of bubbles between the film and the glass more efficient and complete.

[0023] The specific implementation process of this utility model is as follows: In use, after adhering a film to the upper end of the glass, the glass is placed on the upper end of the conveyor roller 2. According to the glass width adjustment device, the motor 32 is started. The motor 32 drives the bidirectional screw 33 to rotate. The rotation of the bidirectional screw 33 and the pressure plate 34 make a threaded movement, thereby causing the pressure plate 34 to move. The movement of the pressure plate 34 compresses the pressure spring 37. The pressure spring 37 compresses the sliding plate 35, thereby causing the guide roller 38 to move. This can limit the glass of different widths and prevent positional deviation during the processing of the device. Then, the screw 51 is manually rotated. The rotation of the screw 51 and the screw barrel 52 make a threaded movement, thereby causing the screw to move. As the cylinder 52 moves downward, it compresses the spring 56, which in turn compresses the hanger 55. The hanger 55 then moves the mounting frame 6, which in turn moves the pressure roller 7. The pressure roller 7 presses the film onto the glass for transport. By rotating the screw 51 and the cylinder 52 in a spiral motion, the cylinder 52 is compressed by the spring 56, causing the mounting frame 6 to move. This ensures that the pressure roller 7 and the scraper 57 remain in contact with the film. The eccentric wheel 510 is driven to rotate by the motor 59 and collide with the baffle 58, causing the scraper 57 to move back and forth, making the removal of air bubbles between the film and the glass more efficient and complete.
