Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive coating equipment, specifically relating to a desktop semi-automatic 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] Spin coaters are devices used to coat the aforementioned lens medium layer. Most existing spin coaters are large-scale machines used for mass lens coating production. However, for different production scales, especially small-scale production, smaller spin coaters are needed to meet production requirements and reduce production costs.

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

[0005] The purpose of this invention is to provide a desktop semi-automatic spin coater, which can solve the problem that spin coaters are mostly large mechanical equipment and cannot be miniaturized for small-scale production.

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

[0007] A benchtop semi-automatic spin coater includes a worktable and a material handling assembly, an adsorption assembly, and an adhesive application assembly disposed on the worktable. Two sets of material handling assemblies are provided for loading and unloading materials. Both sets of material handling assemblies and the adhesive application assembly are located around the adsorption assembly. The material handling end of the material handling assembly can move along a preset circumferential trajectory, and the adhesive application end of the adhesive application assembly can move along a preset straight line trajectory. The two preset circumferential trajectories and the preset straight line trajectories corresponding to the two sets of material handling assemblies intersect at the adsorption assembly.

[0008] In one or more embodiments of the present invention, the material handling assembly includes a rotary drive, a lifting drive disposed at the output end of the rotary drive, and a material handling robot mounted at the output end of the lifting drive. The rotary drive drives the material handling robot to move along the preset circumferential trajectory.

[0009] In one or more embodiments of this utility model, the material handling robot includes two sets of grippers that can move closer or further apart from each other, and the adsorption assembly includes a protective cover installed on the worktable and an adsorption element located inside the protective cover. The adsorption element can be driven to rotate and can adsorb and fix the lens.

[0010] The protective cover has a first clearance groove on the side away from the worktable to avoid the gripper. There are two sets of the first clearance grooves, and the extension directions of the two sets of the first clearance grooves intersect, which are used to avoid the gripper of the two sets of material pick-and-place components.

[0011] In one or more embodiments of the present invention, the adhesive application assembly includes a moving drive and an adhesive application head mounted on the output end of the moving drive. The moving drive drives the adhesive application head to move along the preset straight trajectory. The protective cover also has a second clearance groove to avoid the adhesive application head.

[0012] In one or more embodiments of the present invention, the desktop semi-automatic spin coater further includes a receiving component connected to the protective cover, the receiving component being provided with a receiving groove communicating with the interior of the protective cover, and the coating head being drivably moved within the receiving groove.

[0013] In one or more embodiments of this utility model, the bottom of the receiving tank is provided with a flow guiding surface for guiding the liquid flow to the protective cover.

[0014] In one or more embodiments of this utility model, the adhesive coating assembly is located between two sets of material handling assemblies, and both the material handling assemblies and the adhesive coating assembly are located on the same side of the adsorption assembly.

[0015] In one or more embodiments of this utility model, the two material handling components are arranged symmetrically along a preset straight path relative to the adhesive application end of the adhesive application component.

[0016] In one or more embodiments of the present invention, the tabletop semi-automatic spin coating machine further includes a feeding conveyor belt, the output end of which is located on a preset circumferential path of the feeding end of the feeding assembly used for feeding.

[0017] In one or more embodiments of the present invention, the desktop semi-automatic spin coating machine further includes a feeding conveyor belt, the input end of which is located on a preset circumferential path of the feeding end of the feeding assembly used for feeding.

[0018] Compared with existing technologies, the tabletop semi-automatic spin coater of this invention features two sets of material handling components for loading and unloading, an adsorption component for adsorbing and fixing lenses, and an adhesive application component for applying the coating medium. The two preset circular and linear trajectories corresponding to the two sets of material handling components intersect at the adsorption component. This ensures that the various structures operate independently without interference, and also makes the overall structure more compact and space-saving, meeting the needs of small-scale production and thus reducing production costs.

[0026] 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.

[0027] Reference Figure 1 and Figure 2 In one embodiment of this utility model, a tabletop semi-automatic spin coater includes a worktable 1 and a material handling assembly 2, an adsorption assembly 3, and an adhesive application assembly 4 disposed on the worktable 1. The material handling assembly 2 is provided in two sets for loading and unloading materials. Both sets of the material handling assembly 2 and the adhesive application assembly 4 are located on the periphery of the adsorption assembly 3. The material handling end of the material handling assembly 2 can move along a preset circumferential trajectory, and the adhesive application end of the adhesive application assembly 4 can move along a preset straight line trajectory. The two preset circumferential trajectories and the preset straight line trajectory corresponding to the two sets of material handling assemblies 2 intersect at the adsorption assembly 3.

[0028] In operation, the tabletop semi-automatic spin coating machine of this invention firstly picks up and places the lens on a pre-set circular path to the adsorption component 3, then places the lens on the adsorption component 3 and moves away from it. Next, the adhesive application component 4 moves along a pre-set straight path to the adsorption component 3 to apply adhesive, and then moves away from it. Finally, the unloading component 2 picks up the coated lens from the adsorption component 3 and moves away from it along a pre-set circular path. Therefore, the two pre-set circular paths and the pre-set straight path intersect at the adsorption component 3, ensuring that the various structures do not interfere with each other during operation. In this embodiment, compared to the material handling component 2 moving along a straight path, it moves along a pre-set circular path, while the adhesive application component 4 moves along a pre-set straight path, making the entire structure more compact and space-saving, meeting the needs of small-scale production and thus reducing production costs.

[0029] Reference Figure 2 and Figure 3 The material handling assembly 2 includes a rotary drive 21, a lifting drive 22 disposed at the output end of the rotary drive 21, and a material handling robot 23 mounted at the output end of the lifting drive 22. The rotary drive 21 drives the material handling robot 23 to move along a preset circumferential trajectory. The lifting drive 22 can drive the material handling robot 23 to move closer to or further away from the worktable 1 for picking up or placing materials.

[0030] Reference Figure 3 and Figure 4The material handling robot 23 includes two sets of grippers that can move closer or further apart. The adsorption assembly 3 includes a protective cover 31 mounted on the worktable 1 and an adsorption element 32 located inside the protective cover 31. The adsorption element 32 can be driven to rotate and can adsorb and fix the lens. Specifically, the adsorption element 32 can be driven to rotate by a motor, and the adsorption element 32 can be an adsorption suction cup. Therefore, when the adhesive application assembly 4 applies adhesive to the lens located on the adsorption element 32, the adsorption element 32 can drive the lens to rotate to complete the spin coating work and ensure the uniformity of the medium layer coating. The protective cover 31 can prevent material splashing.

[0031] Reference Figure 3 and Figure 4 The protective cover 31 has a first clearance groove 311 on the side away from the worktable 1 to avoid the grippers. There are two sets of the first clearance groove 311, and the extension directions of the two sets of the first clearance groove 311 intersect to avoid the grippers of the two sets of material handling components 2. Specifically, since the two grippers move linearly and have a fixed stroke range, the first clearance groove 311 can be set to a linear shape according to the stroke of the grippers.

[0032] Reference Figure 3 and Figure 4 The adhesive application assembly 4 includes a moving drive 41 and an adhesive application head 42 mounted on the output end of the moving drive 41. The moving drive 41 drives the adhesive application head 42 to move along a preset straight trajectory. The protective cover 31 also has a second clearance groove 312 to avoid the adhesive application head 42. The second clearance groove 312 can also be set as a straight line.

[0033] Reference Figure 3 and Figure 4 The benchtop semi-automatic spin coater also includes a receiving component 5 connected to the protective cover 31. The receiving component 5 is provided with a receiving groove 51 communicating with the inside of the protective cover 31, and the coating head 42 can be driven to move within the receiving groove 51. The receiving component 5 can collect residual liquid on the coating head 42 and guide it into the protective cover 31. Furthermore, the bottom of the receiving groove 51 is provided with a guide surface 52 for guiding the liquid flow towards the protective cover 31. In this embodiment, the guide surface 52 can be inclined, with its lower inclined end close to the bottom of the protective cover 31, for guiding the liquid flow towards the protective cover 31.

[0034] Reference Figure 2 The adhesive application component 4 is located between the two sets of material handling components 2, and both the material handling components 2 and the adhesive application component 4 are located on the same side of the adsorption component 3. The two material handling components 2 are arranged symmetrically with respect to the preset straight-line path of the adhesive application end of the adhesive application component 4. The above arrangement makes the movement lines of each structure in this application more reasonable, and at the same time makes the overall structure more compact.

[0035] Reference Figure 3In one optional embodiment, the benchtop semi-automatic spin coater further includes a feeding conveyor belt 6 and a discharging conveyor belt 7. The output end of the feeding conveyor belt 6 is located on a preset circumferential path of the feeding end of the feeding assembly 2, and the input end of the discharging conveyor belt 7 is located on a preset circumferential path of the discharging end of the feeding assembly 2. The feeding conveyor belt 6 and the discharging conveyor belt 7 can further improve the operating efficiency of the spin coater and ensure automated operation.
