[0002] The glue coating process is widely used in various industries. The traditional process adopts a simple manual glue coating method. Although the manual glue coating method is flexible and convenient, it has the defects of high labor intensity of workers and high production cost. Therefore, with the gradual development of technology, the glue coating process has gradually changed from the original manual glue coating method to automation. In the field of lens processing, it is usually necessary to coat the peripheral wall of the lens and then send it into a UV baking oven to complete the assembly of the lens.

[0003] Existing glue coating equipment can achieve relatively stable glue coating quality for the glue coating of non - special - shaped lenses, but it is often impossible to coat special - shaped lenses and still relies on manual operation. At the same time, after the glue coating operation is completed, it cannot be automatically sent into the UV baking oven for baking operation.

[0004] Therefore, the utility model proposes a glue coating device for lens processing. Content of the Utility Model

The driven wheel is fixedly connected to the rotating rod, and the driving wheel is connected to the output end of the servo motor and is in transmission connection with the driven wheel through the transmission belt.

[0010] Preferably, the driven wheel is connected to the other end of the rotating rod away from the suction nozzle. The rotating rod is axially provided with a receiving groove for receiving the connecting pipe communicating the suction nozzle with the negative pressure machine.

[0011] Preferably, a spring and a cover adapted to the UV baking oven are sleeved on one end of the rotating rod close to the suction nozzle. The spring is connected between the cover and the linkage member.

[0012] Preferably, the driving member is a hydraulic cylinder. The fixed end of the hydraulic cylinder is hinged to the upper surface of the base, and the movable end of the hydraulic cylinder is connected with a link transmission assembly and is coaxially and rotatably connected to the flipping base through the link transmission assembly.

[0013] Preferably, a translation assembly is provided on the platform. The translation assembly includes a sliding seat, a guide rail, and a lead screw. The lead screw and the guide rail are both installed on the platform, and one end of the lead screw is provided with a knob.

[0014] Preferably, the glue application mechanism includes a glue application tank, a glue application wheel, and a driving motor.

When the limit rod moves upward with the lifting component, it disengages from the limit block. Due to the action of the rotating shaft and the linkage component, the lens adsorption mechanism topples over towards the coating wheel of the coating mechanism on the side as the balance mechanism loses balance and makes the lens abut against the coating wheel. Since the rotation of the coating wheel drives the rotation of the lens, the coating around the lens is completed. After the coating is completed, the lifting component resets to make the limit rod and the limit block keep in the abutting state again, and the lens adsorption mechanism resets to restore balance. Then, under the action of the driving component, the flipping mechanism flips to the UV baking oven on the side for the baking step. The automatic coating of special-shaped lenses and the automatic feeding into the UV baking oven can be realized, improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] This embodiment provides a glue coating device for lens processing, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, which includes a base 1. A pair of platforms 2 are mounted on the base 1. A glue coating mechanism 3 is provided on the platforms 2. The glue coating mechanism includes a rotatable glue coating wheel 32. A flipping mechanism 4 is provided between the platforms 2. The flipping mechanism 4 includes a flipping seat 41 coaxially rotatably connected to the two platforms 2 on both sides and a driving member 42 for coaxial rotation. At least one balancing mechanism 5 is provided on the flipping seat 41. The balancing mechanism 5 includes a bearing seat 51 fixedly installed on the flipping seat 41, a rotating shaft 52 rotatably connected to the bearing seat 51, a lifting assembly 53, and a limiting rod 54 connected to the lifting end of the lifting assembly 53. One end of the rotating shaft 52 is fixedly connected with a counterweight 55 and a limiting block 56 abutted against the limiting rod 54. The other end of the rotating shaft 52 is fixedly connected to one side of a linkage member 57. The other connection of the linkage member 57 is connected with a lens adsorption mechanism 6.

[0029] Working principle: After manually placing the lens to be processed on the lens adsorption mechanism 6 for adsorption and fixation, the balance mechanism 5 releases the abutment between the limit block 56 and the limit rod 54. When the limit rod 54 moves upward with the lifting component 53, it releases the abutment with the limit block 56. Due to the action of the rotating shaft 52 and the linkage 57, the lens adsorption mechanism 6 topples over to the coating wheel 32 of the coating mechanism 3 on the side as the balance mechanism 5 loses balance, and the lens abuts against the coating wheel 32. Since the rotation of the coating wheel 32 drives the rotation of the lens, the coating around the lens is completed. After the coating is completed, the lifting component resets to make the limit rod 54 and the limit block 56 abut again, and the lens adsorption mechanism 6 resets to restore balance. Then, the flipping mechanism 4 flips to the side UV baking oven under the action of the driving member 42 for the baking step, which can realize the automatic coating of special-shaped lenses and the automatic feeding into the UV baking oven, improving production efficiency.

[0030] In this embodiment, as Figure 3 described, the lens adsorption mechanism 6 includes a rotating rod 61 rotatably connected to the linkage 57 and a suction nozzle 62 communicated with a negative pressure machine. The suction nozzle 62 is connected to the rotating rod 61, and the suction nozzle 62 adsorbs the lens. At the same time, when the linkage topples over to the coating mechanism 3 for coating due to the loss of balance of the balance mechanism 5, since the rotating rod 61 can rotate, a force is applied to the rotating rod 61 during the rotation of the coating wheel 32 for coating, so that the lens rotates 360°. Due to the toppling effect, the special-shaped lens always abuts against the coating wheel 32 due to the gravity during rotation.

[0031] In this embodiment, as Figure 2 shown, a self-rotation mechanism 7 for the self-rotation of the lens adsorption mechanism 6 is provided on the flipping seat 41. The self-rotation mechanism 7 includes a servo motor 71 fixedly connected to the flipping seat 41, a driving wheel 72, a transmission belt 73, and a driven wheel 74. The driven wheel 74 is fixedly connected to the rotating rod 61. The driving wheel 72 is connected to the output end of the servo motor 71 and is in transmission connection with the driven wheel 74 through the transmission belt 73. This self-rotation mechanism 7 is for better effect when abutting against the coating wheel 32, rotating better by itself to complete the coating operation more efficiently. At the same time, when the lens is turned to the UV baking oven by the flipping mechanism, the self-rotation mechanism 7 rotates during the baking in the UV baking oven to achieve a more uniform and better baking effect.

[0032] In this embodiment, as Figure 3 shown, the driven wheel 74 is connected to the other end of the rotating rod 61 away from the suction nozzle 62. The rotating rod 61 is axially provided with a receiving groove 75 for receiving the connecting pipe communicating the suction nozzle 62 with the negative pressure machine. Since the lens needs to be fed into the UV baking oven later, such a setting can make the design safer and more reasonable.

[0033] In this embodiment, asFigure 3 As shown, a spring 64 and a cover 63 adapted to the UV baking oven are sleeved on one end of the rotating rod 61 close to the suction nozzle 62. The spring 64 is connected between the cover 63 and the linkage member 57. Since the baking of the UV baking oven is radioactive, in order to prevent excessive radiation spillage, after the suction nozzle and the lens are sent into the UV oven, the cover 63 is abutted against the opening of the UV oven by the action of the spring for sealing.

[0034] In this embodiment, the driving member 42 is a hydraulic cylinder. The fixed end of the hydraulic cylinder is hinged to the upper surface of the base 1, and the movable end of the hydraulic cylinder is connected with a connecting rod transmission assembly 43 and is coaxially rotatably connected with the turning seat 41 through the connecting rod transmission assembly 43. As Figure 2 shown, when the hydraulic cylinder of the hydraulic cylinder expands and contracts, the linear motion force is converted into the force for the turning seat 41 to rotate coaxially through the connecting rod transmission assembly 43. As shown in the figure, the connecting rod transmission assembly 43 is a connecting rod member that changes the force and is hinged to the hydraulic movable end, and the connecting rod member is connected with a rotating shaft. At the same time, this rotating shaft is the shaft for the turning seat 41 to rotate coaxially, and there are a plurality of bearing seats on the platform to adapt to this rotating shaft to realize the coaxial rotation of the turning seat.

[0035] In this embodiment, a translation assembly 8 is provided on the platform 2. The translation assembly 8 includes a sliding seat 81, a guide rail 82 and a lead screw 83. The lead screw 83 and the guide rail 82 are both installed on the platform 2, and a knob 84 is provided at one end of the lead screw 83. The sliding seat 81 is sleeved on the nut seat of the lead screw 83 and is slidably connected with the guide rail 82. A glue application mechanism 3 is connected to the sliding seat 81.

[0036] In this embodiment, as Figure 3 and Figure 4 shown, the glue application mechanism 3 further includes a glue application tank 31 and a driving motor 33. A glue application wheel 32 is rotatably connected in the glue application tank 31. The output shaft of the driving motor 33 penetrates through the glue application tank 31 and is in transmission connection with the glue application wheel 32; an opening is provided above the glue application tank 31, and the upper end of the glue application wheel 32 penetrates through the opening.

[0037] In this embodiment, as Figure 4 shown, a glue amount control assembly 34 is installed at the opening of the glue application tank 31. The glue amount control assembly 34 includes a scraper 341 adapted to the outer circumference of the glue application wheel 32, a guide seat 342 connected to the outer wall of the glue application tank 31 and a push rod 343. The scraper 341 is slidably connected to the guide seat 342, and a push rod 343 is fixedly connected to the end far from the glue application wheel 32. According to needs, the distance between the scraper 341 and the glue application wheel 32 is adjusted by adjusting the push rod 343 to control the glue amount. As Figure 4As shown, the surface of the glue - applying wheel 32 is provided with grooves for adhering the glue in the glue - applying tank 31. The width of the squeegee 341 is adapted to the width of the grooves to scrape off the excess glue and leave it in the glue - applying tank 31.

[0038] In this embodiment, the lifting assembly 53 is a cylinder. The cylinder is vertically installed on the lower surface of the flipping seat 41, and the movable end of the cylinder penetrates through the flipping seat 41 and is connected with a limiting rod 54. The limiting rod 54 is arranged parallel to the flipping seat 41. When the cylinder moves upward, the limiting rod 54 contacts the limiting block for limiting. When the glue - applying is completed, the cylinder resets and the limiting rod 54 abuts against the limiting block again. The limiting block drives the rotating shaft to rotate so that the linkage drives the lens adsorption mechanism to reset.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
