Description

Technical Field

[0001] This utility model relates to the field of camera lens processing technology, specifically a coating machine for optical lens processing. Background Technology

It serves to filter light, improve light transmittance, and prevent ultraviolet rays and stray light from interfering with the lens's color recognition. Camera lenses are a type of optical lens. During the manufacturing process of camera lenses, to prevent dust from accumulating during transport, a protective film is applied to the surface of the optical lens before transport to prevent dust from adhering to the lens surface. In existing technology, the authorized publication number CN... 222292081U proposes a vacuum coating machine for optical lens processing, including a housing. A vacuum mechanism is located on the right side of the housing, a rotating mechanism is located on the front side of the housing, and a coating mechanism is located inside the housing.

A stop block is fixedly connected to the inner side of the housing, and an mounting block is slidably connected to the inner side of the sealing gasket near the door. Although this machine can coat optical lenses, the height of the hot press roller needs to be adjusted according to the thickness of the optical lens during the coating process. During adjustment, the hot press roller may loosen its grip on the film material, and the probability of the film material becoming loose during adjustment is relatively high, resulting in more time being spent adjusting the height of the hot press roller.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5This embodiment provides a technical solution: a coating machine for optical lens processing, including a coating frame 1, an upper film 2 at the upper end of the coating frame 1, a lower film 3 at the lower end of the coating frame 1, and hot press rollers 4 respectively in the middle part of the coating frame 1. The hot press rollers 4 are commonly used in the prior art and include a roller and a heating element. The heating element can be directly heated by an electric heating tube inside the roller. An electric conveyor belt is provided between two horizontal plates of the coating frame 1. The lower hot press roller 4 is rotatably connected between the two horizontal plates of the coating frame 1 and is in contact with the lower surface of the upper belt of the electric conveyor belt. Vertical plates are provided at both the front and rear ends of the upper surface of the coating frame 1. A first unwinding roller is rotatably connected between the upper ends of the two vertical plates of the frame 1. The upper film 2 is set on the outer arc surface of the first unwinding roller. A second unwinding roller is rotatably connected to the lower end of the laminating frame 1. The lower film 3 is set on the outer arc surface of the second unwinding roller. Guide rollers are rotatably connected to both the upper and lower ends of the right side of the laminating frame 1. The upper film 2 passes over the lower surface of the upper guide roller and the lower surface of the lower hot press roller 4 in sequence. The lower film 3 passes over the outer arc surface of the lower guide roller and is conveyed to the left along the upper surface of the electric conveyor belt. A microcontroller 9 is provided on the front surface of the laminating frame 1. The input end of the microcontroller 9 is electrically connected to an external power source. The input end of the hot press roller is electrically connected to the output end of the microcontroller 9 through a collector ring to control the start and stop of the entire device. It also includes an adjustment mechanism 5.

[0022] Adjustment mechanism 5 includes a sliding shell 51, a sliding cylinder 52, and a rotating frame 53. The sliding shell 51 is vertically slidably connected between two vertical plates of the laminating machine frame 1. Adjustable sliding cylinders 52 are vertically slidably connected inside the sliding shell 51. The rotating frame 53 is elastically connected between the lower ends of the two sliding cylinders 52. The upper hot press roller 4 is rotatably connected to the inside of the rotating frame 53 via a rotating shaft. During lamination, the sliding shell 51 moves downward, and under the connection of the sliding cylinders 52 and the rotating frame 53, it drives the upper hot press roller 4 to move downward. Supported by the lower hot press roller 4, the lower film 3 and the upper film 2 are pressed against the upper surface of the electric conveyor belt. The adjustment mechanism 5 also includes a connecting column 54 and a spring 55. The connecting column 54 is vertically slidably connected inside the sliding cylinder 52, and the lower ends of the connecting column 54 all protrude from the sliding cylinder. Inside the slide cylinder 52, the rotating frame 53 is positioned between the lower surfaces of the two connecting columns 54. Springs 55 are provided between the limiting plate at the upper end of the connecting column 54 and the bottom wall of the slide cylinder 52. The springs 55 are movably sleeved on the outer arc surface of the connecting column 54. The adjusting mechanism 5 also includes a sliding column 56, an adjusting plate 57, and inclined grooves 58. The adjusting plates 57 are longitudinally slidably connected to the interior of the sliding shell 51. Inclined grooves 58 are provided on the surface of each adjusting plate 57. The sliding columns 56 are respectively positioned on the outer arc surface of the slide cylinder 52 and are slidably connected to adjacent inclined grooves 58. The two inclined grooves 58 slidably connected to the same sliding column 56 are symmetrical. When the adjusting plate 57 moves, the symmetrical inclined grooves 58 apply two opposite forces to the sliding column 56, thus more stably pushing the slide cylinder 56. The column 56 moves up and down. According to the thickness of the optical lens, the adjusting plate 57 moves, causing the sliding column 56 to slide within the inclined groove 58, pushing the sliding cylinder 52 to move up and down. This changes the distance between the upper surface of the connecting column 54 and the top wall of the sliding cylinder 52. During adjustment, under the elastic force of the spring 55, the connecting column 54 is subjected to a downward force, maintaining the pressure of the upper hot press roller 4 on the upper film 2 and lower film 3, reducing the probability of loosening of the upper film 2 and lower film 3 during adjustment. The adjusting mechanism 5 also includes an electric push rod 59, which is respectively disposed inside the sliding shell 51. The telescopic ends of the electric push rod 59 are fixedly connected to the adjacent adjusting plate 57, and the input end of the electric push rod 59 is electrically connected to the output end of the microcontroller 9, serving as the input for the adjusting plate 57. The movement of the sliding shell 51 is powered by a top plate 6 located in the middle of the top wall of the sliding cylinder 52. A distance sensor 7 is installed in the mounting holes of the top wall of the sliding cylinder 52. The output of the distance sensor 7 is electrically connected to the input of the microcontroller 9. Supported by the top plate 6, direct contact between the connecting column 54 and the top wall of the sliding cylinder 52 is avoided, providing space for the distance sensor 7 to detect the distance. The distance sensor 7 is used to detect the distance between the connecting column 54 and the top wall of the sliding cylinder 52, ensuring the accuracy of the adjustment. A longitudinal plate is provided between the two vertical plates of the laminating frame 1. An electric push rod 8 is installed in the mounting holes on the surface of the longitudinal plate. The lower end of the telescopic end of the electric push rod 8 is fixedly connected to the upper surface of the sliding shell 51. The input of the electric push rod 8 is electrically connected to the output of the microcontroller 9, providing power for the movement of the sliding shell 51.

[0023] The working principle of the coating machine for optical lens processing provided by this utility model is as follows: During the processing of optical lenses for camera lenses, when it is necessary to coat the optical lenses, the microcontroller 9 starts the electric push rod 2 8. The telescopic end of the electric push rod 2 8 drives the sliding shell 51 to move down. Under the connection of the sliding cylinder 52 and the rotating frame 53, it drives the upper hot pressure roller 4 to move down. Under the support of the lower hot pressure roller 4, the lower film 3 and the upper film 2 are pressed against the upper surface of the electric conveyor belt. According to the thickness of the optical lens, the electric push rod 1 59 is started. The telescopic end of the electric push rod 1 59 drives the adjusting plate 57 to move, so that the sliding column 56 slides in the inclined groove 58, pushing the sliding cylinder 52 to move up and down, changing the distance between the upper surface of the connecting column 54 and the top wall of the sliding cylinder 52. During the adjustment process, under the elastic force of the spring 55, the connecting column 54 is subjected to a downward force, maintaining the upper hot pressure roller 4 against the upper film 2 and the lower film 2. The pressure of film 3 reduces the probability of loosening of upper film 2 and lower film 3 during adjustment. After adjustment, the optical lens is placed on the surface of lower film 3, which is conveyed to the left along with the electric conveyor belt. The electric conveyor belt drives the optical lens to the left. During the conveying process, upper film 2 covers the upper surface of the optical lens. When the optical lens moves between the two hot press rollers 4, under the pressure of the optical lens, the elastic force of spring 55 is overcome, and the upper hot press roller 4 moves upward until the connecting column 54 contacts the top plate 6 of the top wall of the slide cylinder 52. The slide cylinder 52 blocks the connecting column 54 from moving upward. At this time, the position of the upper hot press roller 4 is fixed. Affected by the friction between the hot press roller 4, the electric conveyor belt, lower film 3 and upper film 2, the two hot press rollers 4 rotate relative to each other. Through the cooperation of the upper and lower hot press rollers 4, the lower film 3 and upper film 2 are hot-pressed onto the upper and lower surfaces of the optical lens, completing the coating of the optical lens.

[0024] It is worth noting that the microcontroller 9 disclosed in the above embodiments can be an AT89C4051 microcontroller. The ranging sensor 7, electric actuator 59 and electric actuator 8 can be freely configured according to the actual application scenario. The ranging sensor 7 can be a T150HJG-CGQ type reflective laser ranging sensor. Both electric actuator 59 and electric actuator 8 can be ANT-52 type electric actuators. The microcontroller 9 controls the operation of the ranging sensor 7, electric actuator 59 and electric actuator 8 using methods commonly used in the prior art.
