Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive coating equipment, specifically relating to a linear spin coater. Background Technology

[0002] In the manufacturing process of lenses, different dielectric layers need to be coated onto the lenses to meet actual usage requirements. One common example is the protective layer, a coating applied to the lens surface that provides effective protection and improves lens durability. Another example is the photochromic layer, a thin film containing a photosensitive substance that reacts reversibly under UV radiation, changing the lens color and reducing direct sunlight exposure to the eyes.

[0003] A spin coater is a device used to coat the aforementioned medium layer on lenses. In lens processing and production, the spin coater needs to be arranged in conjunction with curing equipment and loading / unloading equipment to complete the lens production line. Currently, the loading and unloading ends of existing spin coaters are located in different directions, resulting in the corresponding arrangement of the equipment in different directions, potentially forming a zigzag layout. This leads to the production line occupying a large amount of factory space, reducing the number of production lines that can be arranged in the factory, and lowering lens production efficiency.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a linear spin coating machine. Utility Model Content

[0005] The purpose of this invention is to provide a linear spin coating machine that can solve the problem that the feeding end and unloading end of the existing spin coating machine have different orientations, which reduces the number of work lines that can be arranged in the factory and reduces the production efficiency of lenses.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A linear spin coating machine includes a worktable and a feeding conveyor belt, a feeding component, an adsorption component, and a discharging component disposed on the worktable. The feeding component is used to pick up lenses from the feeding conveyor belt and place them at the adsorption station of the adsorption component. The discharging component picks up lenses from the adsorption station and discharges them. The feeding component, the adsorption component, and the discharging component are all arranged along the conveying direction of the feeding conveyor belt, and the adsorption component is located between the feeding component and the discharging component.

[0008] In one or more embodiments of this utility model, the feeding assembly includes a mounting frame slidably disposed with the worktable and a feeding robot mounted on the mounting frame. The mounting frame can be driven to move in the same direction as the conveying direction of the feeding conveyor belt, and the feeding robot is located above the feeding conveyor belt.

[0009] In one or more embodiments of this utility model, the unloading assembly includes a rotating module mounted on the worktable and an unloading robot mounted on the output end of the rotating module. The rotating module drives the unloading robot to rotate towards the material picking position of the adsorption assembly, or away from the material unloading position of the adsorption assembly.

[0010] In one or more embodiments of the present invention, the linear spin coater further includes a coating assembly, which cooperates with the adsorption assembly. The coating assembly includes a moving drive and a coating head disposed at the output end of the moving drive. The moving drive drives the coating head to move closer to or away from the adsorption assembly.

[0011] In one or more embodiments of this utility model, the glue application assembly is located on the side of the conveying direction of the feeding conveyor belt, and the moving drive unit drives the glue application head to move in a direction that intersects with the conveying direction of the feeding conveyor belt.

[0012] In one or more embodiments of the present invention, the adsorption assembly includes a protective cover installed at the adsorption station and an adsorption element located inside the protective cover. The adsorption element can be driven to rotate and can adsorb and fix the lens.

[0013] In one or more embodiments of the present invention, the protective cover includes a cover body fixed to the workbench and a cover plate covering the cover body, the cover plate being provided with a clearance hole for the material loading and unloading ends of the loading and unloading components to pass through.

[0014] In one or more embodiments of this utility model, at least two sets of feeding conveyor belts are arranged in parallel, and each feeding conveyor belt is provided with the adsorption component, the feeding component and the unloading component in the conveying direction.

[0015] In one or more embodiments of this utility model, the feeding component is provided with a material picking and dispensing end corresponding to the number and position of the feeding conveyor belt, and the unloading component is provided with a material picking and dispensing end corresponding to the number and position of the adsorption components.

[0016] In one or more embodiments of the present invention, the linear spin coating machine further includes a feeding conveyor belt, which is located on the side of the feeding assembly away from the adsorption assembly, and the feeding conveyor belt and the feeding conveyor belt have the same conveying direction.

[0017] Compared with existing technologies, the linear spin coater of this invention uses a feeding conveyor belt to transport lenses. The feeding assembly picks up lenses from the feeding conveyor belt and places them at the adsorption station of the adsorption assembly for subsequent spin coating. The unloading assembly removes the spin-coated lenses from the adsorption station. In this application, the feeding assembly, adsorption assembly, and unloading assembly are all arranged along the conveying direction of the feeding conveyor belt, facilitating subsequent connection with other equipment to form a linear work line. This increases the number of work lines that can be arranged in the factory and improves lens production efficiency. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0026] Reference Figure 1 In one embodiment of this utility model, the linear spin coating machine includes a worktable 1 and a feeding conveyor belt 2, a feeding component 3, an adsorption component 4, a discharging component 5, and an adhesive coating component 6 disposed on the worktable 1.

[0027] Reference Figure 1 The loading assembly 3 is used to pick up lenses from the loading conveyor belt 2 and place them at the adsorption station of the adsorption assembly 4. The unloading assembly 5 picks up lenses from the adsorption station and unloads them. The loading assembly 3, adsorption assembly 4, and unloading assembly 5 are all arranged along the conveying direction of the loading conveyor belt 2, with the adsorption assembly 4 located between the loading assembly 3 and the unloading assembly 5. The adhesive application assembly 6 works in conjunction with the adsorption assembly 4 to apply adhesive to the lenses.

[0028] In use, the linear spin coater of this invention employs a feeding conveyor belt 2 to transport lenses. The feeding assembly 3 picks up lenses from the feeding conveyor belt 2 and places them at the adsorption station of the adsorption assembly 4. The coating assembly 6 applies photochromic or protective layer material to the lenses at the adsorption station. The unloading assembly 5 removes the spin-coated lenses from the adsorption station. In this application, the feeding assembly 3, adsorption assembly 4, and unloading assembly 5 are all arranged along the conveying direction of the feeding conveyor belt 2, facilitating subsequent connection with other equipment (such as a curing oven) to form a linear work line. Therefore, compared to a zigzag work line (such as an L-shaped work line), a linear work line occupies less space, increases the number of work lines that can be arranged in the factory, and improves lens production efficiency.

[0029] Reference Figure 1 At least two sets of feeding conveyor belts 2 are arranged side by side. Each feeding conveyor belt 2 is equipped with an adsorption component 4, a feeding component 3, and a discharging component 5 in its conveying direction. In this embodiment, two sets of feeding conveyor belts 2 are arranged side by side as an example for illustrative purposes. In other embodiments, the number of feeding conveyor belts 2 can also be other, such as three, four, or even more sets. This application does not impose specific limitations on this. It is understood that by setting multiple sets of feeding conveyor belts 2 arranged side by side, the production speed of lenses can be further accelerated while ensuring a straight working line.

[0030] Reference Figure 2 and Figure 3The feeding assembly 3 includes a mounting frame 31 slidably disposed with the worktable 1 and a feeding robot 32 mounted on the mounting frame 31. The mounting frame 31 can be driven to move in the same direction as the conveying direction of the feeding conveyor belt 2, and the feeding robot 32 is located above the feeding conveyor belt 2. The movement direction of the mounting frame 31 is consistent with the conveying direction of the feeding conveyor belt 2, which facilitates the formation of a straight working line. Specifically, the mounting frame 31 can be driven to move by a cylinder. In this embodiment, the feeding assembly 3 is provided with picking and placing ends corresponding to the number and position of the feeding conveyor belt 2, that is, the mounting frame 31 can specifically be equipped with two sets of feeding robots 32. In this embodiment, the mounting frame 31 can specifically be a gantry frame and located above the feeding conveyor belt 2. The feeding robot 32 can specifically include two sets of grippers that can be driven to move closer or further apart from each other and a lifting drive component that drives the grippers to rise and fall.

[0031] Reference Figure 2 and Figure 3 The unloading component 5 includes a rotating module 51 mounted on the workbench 1 and an unloading robot 52 mounted on the output end of the rotating module 51. The rotating module 51 drives the unloading robot 52 to rotate and move closer to the picking position of the adsorption component 4, or away from the unloading position of the adsorption component 4. The unloading component 5 is provided with picking and unloading ends corresponding to the number and position of the adsorption components 4. That is, in this embodiment, the output end of the rotating module 51 can be provided with two sets of unloading robots 52. The unloading robots 52 can have the same structure as the loading robots 32 and are used for picking and unloading materials. In this embodiment, the unloading component 5 can place lenses at single or multiple points. Single-point placement on the conveyor belt of the next process can form a straight line arrangement when the belt is running at a constant speed. Multi-point placement on the conveyor belt can form an arc-shaped matrix arrangement when the belt is running at a constant speed. This application does not impose specific limitations on the above placement forms; specific settings can be made according to actual conditions.

[0032] Reference Figure 3 and Figure 4 The adsorption assembly 4 includes a protective cover 41 installed at the adsorption station and an adsorption element 42 located inside the protective cover 41. The adsorption element 42 can be driven to rotate and can adsorb and fix the lens. The adsorption element 42 can specifically be a vacuum suction cup. The protective cover 41 includes a cover body 411 fixed to the worktable 1 and a cover plate 412 covering the cover body 411. The cover plate 412 is provided with a clearance hole 413 for the material feeding assembly 3 and the material unloading assembly 5 to pass through. The glue application assembly 6 cooperates with the adsorption assembly 4. The glue application assembly 6 includes a moving drive 61 and a glue application head 62 provided at the output end of the moving drive 61. The moving drive 61 drives the glue application head 62 to move closer to or away from the adsorption assembly 4.

[0033] In this embodiment, when the moving drive 61 drives the coating head 62 to approach the adsorption station, it can apply photochromic layer or protective layer material to the lens located at the adsorption station. At the same time, the adsorption member 42 is driven to rotate to complete the spin coating of the photochromic layer or protective layer on the lens surface. The cover 411 can prevent paint from splashing everywhere, and the clearance hole of the cover plate 412 allows the material loading and unloading ends of the loading and unloading components 3 and 5 to pass through, so as to complete the material loading and unloading actions respectively.

[0034] Reference Figure 3 The coating assembly 6 is located on the side of the feeding conveyor belt 2 along its conveying direction. The moving drive unit 61 drives the coating head 62 to move in a direction intersecting with the conveying direction of the feeding conveyor belt 2. The positioning of the moving drive unit 61 avoids interference with the material handling paths of the feeding assembly 3 and the unloading assembly 5, ensuring a reasonable workflow for completing the lens spin coating. In this embodiment, the moving direction of the coating head 62 is perpendicular to the conveying direction of the feeding conveyor belt 2.

[0035] Reference Figure 1 In one optional embodiment, the linear spin coater further includes a feeding conveyor belt located on the side of the feeding assembly 5 away from the adsorption assembly 4, and the feeding conveyor belt and the loading conveyor belt 2 have the same conveying direction. This arrangement of the feeding conveyor belt and the loading conveyor belt 2 further ensures a linear work line, further improves feeding efficiency, and ensures lens production efficiency.
