Description

Technical Field

[0001] This utility model relates to the field of glue application device technology, and in particular to an optical lens glue application device. Background Technology

[0002] Optical lenses are core components of optical systems, primarily used for refracting, reflecting, or modulating light. They are widely used in eyeglasses, cameras, microscopes, telescopes, laser equipment, and other fields. During the manufacturing process, two lenses are bonded together. Currently, this is done using a glue applicator to evenly apply adhesive to the edges of the lens. After the adhesive is applied, the lens is removed and transferred to a bonding device where it is bonded to another lens (the other lens may or may not be coated with adhesive, depending on the situation). However, the process is cumbersome. Workers place the lens on the glue applicator, apply adhesive using a dispensing pen, and then remove the glued lens to replace it with another lens to be glued. Furthermore, after the lens is glued, workers are prone to touching the adhesive when handling it, which can disrupt the uniformity of the adhesive distribution and affect the quality of the final bonded lens. Utility Model Content

[0003] This utility model discloses an optical lens adhesive application device, which solves the problem that after the lens is applied, the staff can easily touch the glue when handling the lens, which disrupts the uniformity of the glue distribution on the lens.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An optical lens gluing device includes a worktable, a rotatable connecting plate on the top of the worktable, and electromagnets of type I fixed around the perimeter of the connecting plate. A support block is attracted to the electromagnet of type I, and a recessed hole for placing the lens is opened on the top of the support block. A dispensing pen is placed above the support block. A top plate is provided above the worktable, and a slidable electric telescopic rod of type I is provided on the top plate. A second electromagnet is fixed to the telescopic end of the electric telescopic rod of type I. A drive assembly for driving the electric telescopic rod of type I is provided on the top plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The lens is placed in the recess on the support block, and then the first electromagnet is energized to generate magnetic force that attracts the support block. Once the support block moves the lens directly under the dispensing pen, glue is applied to the lens using the pen. After the glue is applied, the connecting plate rotates, causing the first electromagnet to rotate the support block. When the lens with glue applied moves away from under the dispensing pen, the telescopic end of the first electric telescopic rod extends, bringing the second electromagnet closer to the support block and energizing it. When the drive assembly moves the first electric telescopic rod, the second electromagnet contacts the support block, thus attracting it. The first electromagnet in contact with the support block is then de-energized. Electromagnet No. 2 transfers the carrier block and lens together, allowing subsequent workers to transfer the lens to the next processing step by picking up the carrier block. A set of electromagnets No. 1 can hold a set of carrier blocks, and by rotating the connecting plate, the lenses can be glued sequentially without the need for manual material removal. This invention eliminates the need for manual removal of glued lenses, and allows for continuous glue application to subsequent lenses without machine downtime, improving glue application efficiency. Furthermore, the lens transfer process avoids direct contact with the worker's hands, preventing disruption of the glue's uniform distribution on the lens. Attached Figure Description

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an optical lens gluing device, including a worktable 1, a rotatable connecting plate 2 on the top of the worktable 1, a first electromagnet 21 fixed around the four sides of the connecting plate 2, a support block 3 adsorbed on the first electromagnet 21, a concave hole 4 for placing the lens on the top of the support block 3, and a dispensing pen 5 above the support block 3; a top plate 6 is provided above the worktable 1, and a slidable first electric telescopic rod 61 is provided on the top plate 6, a second electromagnet 62 is fixed to the telescopic end of the first electric telescopic rod 61, and a driving assembly for driving the first electric telescopic rod 61 is provided on the top plate 6. The dispensing pen 5 is a pneumatic glue-storing type dispensing pen. This model of dispensing pen 5 is a very mature existing technology, and will not be described in detail here. After placing the lens in the recess 4 on the support block 3, a set of support blocks 3 are then brought into contact with the first electromagnet 21 located around the connecting plate 2, so that the first electromagnet 21 is energized and attracts the support block 3. By rotating the connecting plate 2, the lens in the recess 4 on one support block 3 corresponds to the dispensing pen 5, and the dispensing pen 5 can then apply glue to the designated position on the lens. After the glue is applied, the connecting plate 2 continues to rotate, so that another support block 3 moves the lens to be glued to below the dispensing pen 5. The glued lens then moves toward the second electromagnet 62. After the support block 3 moves the glued lens to the designated position, the extension end of the first electric telescopic rod 61 drives the second electromagnet 62 to move downwards to be flush with the support block 3. The system is set to a level height, and then the drive assembly drives the first electric telescopic rod 61 to approach the support block 3, energizing the second electromagnet 62 and bringing it into contact with the support block 3, thus attracting the support block 3. At the same time, the first electromagnet 21, which is attracted to the support block 3, is de-energized. Subsequently, the drive assembly drives the first electric telescopic rod 61 away from the connecting plate 2, causing the second electromagnet 62 to pull the support block 3 away from the first electromagnet 21, completing the unloading of the lens. There is no need for the staff to manually remove the lens. Afterwards, the staff can transfer the lens to the external pressing equipment through the support block 3, so that the lens is located in the recess 4 on the support block 3. After the lens pressing operation is completed, the lens can be removed. At the same time, after the first electromagnet 21 is de-energized, the staff can continue to contact the other support block 3 containing the lens with the first electromagnet 21, so that the first electromagnet 21 attracts the support block 3.

[0014] like Figure 1 As shown, a No. 1 motor 23 is fixed on the workbench 1. A rotating rod 22 connected to the connecting plate 2 is fixed on the rotating shaft of the No. 1 motor 23, and a storage battery 24 is fixed on the rotating rod 22. The main body of the No. 1 motor 23 is fixed to the bottom of the workbench 1, and the rotating shaft of the No. 1 motor 23 passes through the workbench 1. After the No. 1 motor 23 is started, the connecting plate 2 can be driven to rotate through the rotating rod 22, and the storage battery 24 can supply power to the No. 1 electromagnet 21.

[0015] like Figure 1 As shown, the drive assembly includes a second motor 7 fixed on the top plate 6, a lead screw 71 fixed on the shaft of the second motor 7, and a movable plate 72 threadedly connected to the fixed end of the first electric telescopic rod 61 on the lead screw 71; the connecting plate 2 is located between the dispensing pen 5 and the second electromagnet 62. A support plate is fixed between the top plate 6 and the worktable 1. The end of the lead screw 71 away from the second motor 7 is rotatably connected to a fixed block fixed to the bottom of the top plate 6. After the second motor 7 is started to rotate the lead screw 71, the moving plate 72 can move laterally. The moving plate 72 can drive the second electromagnet 62 to move through the first electric telescopic rod 61. The top of the second electromagnet 62 is fixed with a connecting strip that is fixed to the telescopic end of the first electric telescopic rod 61. The connecting plate 2 is located between the dispensing pen 5 and the second electromagnet 62 so that after the lens dispensing is completed, as the connecting plate 2 rotates, when the carrier block 3 carrying the dispensed lens moves to a position close to the second electromagnet 62, the second electromagnet 62 can perform the unloading operation on the carrier block 3 without affecting the dispensing pen 5's subsequent lens dispensing operation.

[0016] like Figure 1 and Figure 2 As shown, a second electric telescopic rod 8 is fixed to the top of the top plate 6. A third motor 81 is fixed to the telescopic end of the second electric telescopic rod 8 via a fixing plate. A connecting block 82 is fixed to the rotating shaft of the third motor 81. A moving block 83, which is fixed to the dispensing pen 5, is provided on the connecting block 82. The telescopic end of the second electric telescopic rod 8 passes through the top plate 6. After the second electric telescopic rod 8 is started, the third motor 81 can be driven to move downward, so that the connecting block 82 drives the dispensing pen 5 downward through the moving block 83, so that the dispensing pen 5 can perform glue application on the lens (the dispensing pen 5 corresponds to the concave hole 4 of the bearing block 3 located directly below). After the third motor 81 is started, the dispensing pen 5 can be driven to rotate, so as to perform glue application on the lens from all directions.

[0017] like Figure 1 and Figure 2 As shown, the connecting block 82 is L-shaped, and the moving block 83 is T-shaped and slidably connected to the top of the connecting block 82. A screw 84 is threaded onto the connecting block 82, and one end of the screw 84 is rotatably connected to the moving block 83. The glue delivery tube of the dispensing pen 5 passes through the vertical part of the moving block 83. By rotating the screw 84, the moving block 83 can be moved, changing the glue application area of ​​the dispensing pen 5 on the lens. The position of the dispensing pen 5 can also be adjusted according to the size of the lens. At the same time, the recessed holes 4 on the carrier block 3 can be made according to the lens model to facilitate the preparation of multiple batches of carrier blocks 3 with different recessed hole sizes for placing different models of lenses.

[0018] like Figure 1As shown, a third electric telescopic rod 9 is fixed on the workbench 1. The telescopic end of the third electric telescopic rod 9 is fixed with a support plate 91 that is slidably connected to the workbench 1. The support plate 91 is located below the second electromagnet 62. Two loading frames 92 are placed on the support plate 91. A limiting plate 93 is fixed on the support plate 91 to block the loading frames 92. A carrier block 3 containing a lens to be coated can be placed in a loading frame 92, and another loading frame 92 can be used to place a carrier block 3 containing a lens that has been coated. At the same time, the third electric telescopic rod 9 can be activated to move the two loading frames 92 through the carrier plate 91, so that when the first electric telescopic rod 61 moves laterally, it can better place the carrier block 3 containing the coated lens in a loading frame 92. After the first electric telescopic rod 61 continues to move, it can pick up another carrier block 3 containing a lens to be coated for automatic feeding. The first electric telescopic rod 61, the second electric telescopic rod 8, the third electric telescopic rod 9, the first motor 23, the second motor 7, the third motor 81, the first electromagnet 21, the second electromagnet 62, and the glue pen 5 are controlled by an external control panel. The control program of the external control panel is a very mature existing technology, which will not be described in detail here. The first motor 23, the second motor 7, and the third motor 81 are all servo motors.

[0019] like Figure 1 and Figure 3 As shown, two iron plates 31 are fixed on the bearing block 3, and the bearing block 3 is located between the two iron plates 31. A limiting rod 32 is fixed on one of the iron plates 31 near the connecting plate 2. The connecting plate 2 has a limiting hole for the limiting rod 32 to be inserted. The iron plate 31 is designed to attract the iron plate 31 after the first electromagnet 21 and the second electromagnet 62 are energized. The iron plate 31 with the limiting rod 32 has two limiting rods 32. When the limiting rod 32 is inserted into the limiting hole on the connecting plate 2, the first electromagnet 21 is located between the two limiting rods 32. The setting of two limiting rods 32 can further increase the firmness of the connection between the bearing block 3 and the connecting plate 2.

[0020] like Figure 1 and Figure 3 As shown, a liftable support plate 41 is slidably connected inside the recess 4. The bottom of the support block 3 has a through hole communicating with the bottom of the recess 4. A short rod 42 is fixed to the bottom of the support plate 41 within the through hole. A magnetic block 43, in contact with the bottom of the support plate 41, is fixed inside the through hole. The support plate 41 is made of steel, and a push plate 44 is fixed to the bottom of the short rod 42. When it is necessary to remove the lens from the recess 4, the short rod 42 can be pushed by the push plate 44 to move the support plate 41 upwards, pushing the lens out. The magnetic block 43 can hold the support plate 41 in place, preventing it from moving freely.

[0021] like Figure 1 As shown, the connecting plate 2 is arranged in a cross shape, and a collection box 11 is placed on top of the workbench 1, directly below the dispensing pen 5. The connecting plate 2 is arranged in a cross shape, and four electromagnets 21 can be installed on the connecting plate 2. The collection box 11 can collect the glue dripping from the dispensing pen 5.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
