Description

Technical Field

[0001] The utility model belongs to the technical field of gluing equipment, and particularly relates to a gluing machine. Background Art

[0002] In the processing and production of lenses, different dielectric layers need to be coated on the lenses to meet actual requirements. For example, a protective layer is a common coating applied to the surface of a lens, which can provide effective protection for the lens and thus improve the durability of the lens during use.

[0003] A gluing machine is a device for coating the dielectric layer of a lens. During gluing, the lens is usually grabbed by a manipulator, and then the manipulator moves along the guide rail to the spin coating station and places the lens on the spin coating station. Then, the coating is dripped onto the lens, and the lens is driven to rotate to complete the coating of the dielectric layer on the lens surface by centrifugal force.

[0004] The guide rail in the gluing machine is usually installed in a wall-mounted manner, and the spin coating station is arranged on the workbench and below the guide rail. This installation method causes the guide rail to bear a large bending moment from the manipulator on the one hand; on the other hand, some dust may fall onto the spin coating station during the reciprocating movement of the manipulator along the guide rail, resulting in possible impurities on the protective layer of the lens surface and affecting the gluing quality.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a gluing machine.

[0006] The information disclosed in this background art section is only for increasing the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a gluing machine, which can solve the problems of relatively poor structural stability and relatively poor coating effect of the lens caused by the wall-mounted installation method of the guide rail as mentioned above.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] Referring to Figure 1 , the glue applicator in an embodiment of the present utility model includes a workbench 1, a guide rail 2, a material taking assembly 3, an adsorption assembly 4, a spraying assembly 5, a feeding conveyor belt 6 and a discharging conveyor belt 7.

[0030] Referring to Figure 1 and Figure 2 , the guide rail 2 is horizontally installed on the tabletop of the workbench 1, and the material taking assembly 3 is slidably installed on the side of the guide rail 2 away from the workbench 1. The adsorption assembly 4 is installed on the tabletop of the workbench 1 and is located on the side of the extension direction of the guide rail 2. The material taking assembly 3 can be controllably slid along the extension direction of the guide rail 2 to pick up and place the lens on the adsorption assembly 4. The spraying assembly 5 is cooperatively installed with the adsorption assembly 4 for spraying the coating on the lens on the adsorption assembly 4.

[0031] Referring to Figure 2 , the feeding conveyor belt 6 and the discharging conveyor belt 7 are installed on the workbench 1, and the feeding conveyor belt 6 and the discharging conveyor belt 7 are respectively located at both ends of the guide rail 2. The material taking assembly 3 includes a first material taking assembly and a second material taking assembly. The first material taking assembly is used to transfer the lens on the feeding conveyor belt 6 to the adsorption assembly 4, and the second material taking assembly is used to transfer the lens on the adsorption assembly 4 to the discharging conveyor belt 7.

[0032] During operation, the first material taking assembly obtains the lens from the feeding conveyor belt 6, moves along the guide rail 2 and places the lens on the adsorption assembly 4. Then, the adsorption assembly 4 cooperates with the spraying assembly 5 to complete the coating of the surface protection layer of the lens. After the coating is completed, the second material taking assembly moves along the guide rail 2 to the adsorption assembly 4, and then takes out the coated lens from the adsorption assembly 4 to the discharging conveyor belt 7. In this embodiment, the coating method of the lens adopts the spin coating method, that is, the coating of the lens is completed by using the rotational centrifugal force.

[0033] It can be understood that, compared with setting the guide rail 2 as a wall-mounted installation, the guide rail 2 in this embodiment adopts a horizontal installation, so that the bending moment that the guide rail 2 may bear can be reduced, and the structural stability is improved. At the same time, in this embodiment, the adsorption assembly 4 is located on the side of the guide rail 2 and is in the same installation plane as the guide rail 2, so that the possibility of dust on the guide rail 2 falling onto the lens due to the movement of the material taking assembly 3 along the guide rail 2 can be reduced, and the quality of spin coating is ensured.

[0034] Referring to Figure 1 and Figure 3 , the adsorption assembly 4 includes a cylinder body 41 fixedly installed on the workbench 1 and an adsorption head 42 installed in the cylinder body 41. The height of the cylinder body 41 is greater than the height of the guide rail 2. A cover body 43 is provided on the side of the cylinder body 41 away from the workbench 1, and the cover body 43 is provided with an installation hole 431 for the lens to pass through. In this embodiment, the adsorption head 42 is set as a suction cup, and the lens is fixed by vacuum adsorption.

[0035] Among them, the height settings of the cylinder body 41, the cover body 43, and the cylinder body 41 can further reduce the possibility of the lens on the suction head 42 being contaminated with dust. At the same time, since the coating process of the lens in this embodiment adopts the spin coating method, the suction head 42 is arranged inside the cylinder body 41, which can effectively prevent the paint from splashing, and can also recycle the paint in an organized manner, reducing the coating cost of the lens.

[0036] It should be noted that the adsorption assembly 4 in this embodiment further includes a rotating member that can drive the suction head 42 to rotate. The rotating member is not shown in the drawings. Since the rotating member that drives the suction head 42 to rotate is a conventional structure in the art, it will not be described in detail in this embodiment.

[0037] Refer to Figure 3 , the spraying assembly 5 includes a moving member 51 and a glue coating head 52. The moving member 51 drives the glue coating head 52 to approach or move away from the suction head 42. During operation, the moving member 51 drives the glue coating head 52 to approach the cylinder body 41 and sprays paint on the lens on the suction head 42, thereby completing the spin coating of the lens. Among them, for example, the moving member 51 can be provided with a plurality of cylinders that can move in different directions. By controlling the coordinated operation of the plurality of cylinders, the glue coating head 52 is driven to move in the corresponding direction.

[0038] Refer to Figure 3 , a receiving pipe 44 communicating with the inside of the cylinder body 41 is provided on one side of the cylinder body 41; when the glue coating head 52 is driven to the maximum position away from the suction head 42, the glue coating head 52 is located directly above the pipe orifice of the receiving pipe 44. Therefore, when the coating assembly does not spray, the receiving pipe 44 can effectively receive the remaining paint that may drip from the glue coating head 52.

[0039] Furthermore, the receiving pipe 44 is inclined with respect to the axis line of the cylinder body 41. Therefore, the paint dripping from the glue coating head 52 can flow into the cylinder body 41 along the receiving pipe 44.

[0040] Refer to Figure 3 and Figure 4 , the material taking assembly 3 includes at least two groups of clamping jaws 31. The at least two groups of clamping jaws 31 include a material grabbing position close to each other and a material releasing position far from each other. The cover body 43 is also provided with an avoidance hole 432 for the clamping jaws 31 to pass through. The extending direction of the avoidance hole 432 is the same as the displacement direction of the corresponding clamping jaw 31 between the material grabbing position and the material releasing position. The setting of the avoidance hole 432 facilitates the material taking assembly 3 to take and place the lens at the suction head 42.

[0041] Refer to Figure 2, at least two spraying assemblies 5 are arranged in parallel on the workbench 1. Any spraying assembly 5 includes at least two glue applicator heads 52, and the number and positions of the cylinders 41 correspond to the number and positions of the glue applicator heads 52. By arranging multiple spraying assemblies 5, and correspondingly arranging multiple glue applicator heads 52 and cylinders 41, the coating efficiency of the lenses can be effectively improved.

[0042] Referring to Figure 2 , a curing assembly 8 for curing the surface coating of the lenses is arranged on the blanking conveyor belt 7. In this embodiment, the curing assembly 8 cures the coating on the surface layer of the lenses by means of ultraviolet curing. For example, the curing assembly 8 can install a housing above the blanking conveyor belt 7 and arrange ultraviolet light equipment inside the housing.
