Description

Technical Field

[0001] This utility model relates to the field of lens processing equipment technology, and in particular to an automatic dispensing and curing device for lenses of vision training equipment. Background Technology

[0002] In the production and manufacturing of visual function-related equipment such as myopia control, strabismus and amblyopia diagnosis and training equipment, the lens, as the core optical component, directly determines the training effect and the accuracy of the examination results. If the light transmittance decreases due to contamination, it will lead to the attenuation and distortion of the optical signal output by the equipment, which will prevent patients from receiving accurate visual stimulation during training, affecting the myopia control and strabismus and amblyopia correction effects. It will also cause doctors to make misjudgments based on the equipment examination results, interfering with the diagnosis and treatment process.

[0003] Currently, the bonding process for lenses in vision training equipment relies on existing automated adhesive application equipment. However, because the adhesive remains uncured and flowing after application, it easily flows into the optical areas of the lens during lens transfer or subsequent processes, causing contamination. Furthermore, the lack of adaptability to vision training equipment lenses in existing equipment leads to insufficient precision in application location and inconsistent adhesive dosage control, increasing the risk of adhesive overflow and contamination of the lens.

[0004] Therefore, there is an urgent need for an automatic dispensing and curing device for lenses in vision training equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic dispensing and curing device for lenses of vision training equipment. This addresses the problem in existing automatic dispensing equipment where, after application, the adhesive remains in an uncured, flowing state, causing it to easily flow into the optical area of ​​the lens and contaminate it during lens transfer or subsequent processes. Furthermore, existing dispensing equipment lacks a design specifically adapted for vision training equipment lenses, resulting in insufficient dispensing accuracy and unstable adhesive dosage control, increasing the risk of adhesive overflow and contamination. The preferred technical solutions provided by this invention offer numerous advantages, which are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides an automatic dispensing and curing device for lenses in a vision training equipment, comprising a base, a dispensing execution unit, a glue storage unit, a curing unit, and a central control unit, wherein: The base is provided with a material support position, which is used to accommodate the eyepiece disk; The dispensing execution unit includes a driving mechanism and a dispensing mechanism. The driving mechanism is disposed on the base, and the dispensing mechanism is connected to the driving mechanism. The glue storage unit is connected to the glue dispensing mechanism via a delivery pipeline; The curing unit is disposed on the driving mechanism. The effective area of ​​the curing unit covers all the preset dispensing positions of the dispensing mechanism on the material carrier position. The curing unit maintains a preset distance from the dispensing mechanism so as to cure the adhesive after the dispensing mechanism completes the dispensing. Both the drive mechanism and the curing unit are electrically connected to the main control unit.

[0007] Preferably, it further includes a gas source and a gas source control unit, wherein: The gas source control unit is signal-connected to the main control unit; The air source is connected to the dispensing mechanism via an air pipe through the air source control unit, and the air source control unit is used to control the dispensing time and air pressure.

[0008] Preferably, the driving mechanism includes a multi-axis driving unit, which can drive the dispensing mechanism and the curing unit to move along a preset trajectory in three-dimensional space.

[0009] Preferably, the multi-axis drive unit includes a linear module.

[0010] Preferably, the curing unit is a photocuring component, and the irradiation parameters of the photocuring component are set by the central control unit. The irradiation parameters include irradiation time and irradiation intensity.

[0016] This utility model provides an automatic dispensing and curing device for lenses in visual function training equipment.

The dispensing execution unit comprises a drive mechanism and a dispensing mechanism, connected to the drive mechanism. The curing unit is mounted on the drive mechanism, and both are electrically connected to the central control unit. The central control unit coordinates the operation of the drive mechanism and the curing unit, achieving precise linkage between the dispensing and curing processes. This avoids timing deviations caused by manual operation, ensuring the glue cures at the optimal time and improving the stability of lens adhesion. By setting the curing unit's effective area to cover all preset dispensing positions on the material carrier, and maintaining a preset distance between the curing unit and the dispensing mechanism, the glue can be cured promptly after dispensing, significantly shortening the glue flow time and effectively reducing glue overflow into the optical area of ​​the lens, thus ensuring the light transmittance of the visual function training equipment lenses and preventing any impact on training and inspection results. The entire device integrates dispensing, storage, and curing functions into one unit, with the curing unit integrated into the drive mechanism. The layout is reasonable, reducing the space occupied by the equipment. The whole process is fully automated through the central control unit, reducing manual intervention and operational errors. At the same time, it enables continuous production and significantly improves the processing efficiency of lenses for vision training equipment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figure 1 As shown, this embodiment provides an automatic dispensing and curing device for lenses of a vision training device, including a base 1, a dispensing execution unit 2, a glue storage unit 3, a curing unit 4, and a central control unit 5.

[0024] The base 1 is provided with a material support position 10, which is used to accommodate the eyepiece disk 6. A lens is placed in the preset mounting position of the eyepiece disk 6. When the automatic dispensing and curing device is working, the dispensing execution unit 2 accurately dispenses adhesive at the gap between the eyepiece disk 6 and the lens. The adhesive must cover the contact area between the lens and the eyepiece disk to ensure the bonding strength.

[0025] Optionally, the material carrier position 10 in this embodiment is provided with a positioning pin and / or a limiting protrusion. The positioning pin and the limiting protrusion are used for positioning, which can accurately accommodate and position the eyepiece disk 6 to ensure the accuracy of the dispensing position.

[0026] like Figure 1 and Figure 2 As shown, the dispensing execution unit 2 includes a drive mechanism 21 and a dispensing mechanism 22. The drive mechanism 21 is disposed on the base 1, and the dispensing mechanism 22 is connected to the drive mechanism 21.

[0027] Optionally, the drive mechanism 21 in this embodiment includes a multi-axis drive unit, which includes X-axis, Y-axis, and Z-axis linear modules. The guide rails of each module adopt a precision ball screw structure, and the travel of the X-axis and Y-axis is not less than 500 mm, while the travel of the Z-axis is not less than 200 mm. The multi-axis drive unit is driven by a servo motor to ensure that the dispensing mechanism 22 moves smoothly and is positioned accurately.

[0028] Specifically, in this embodiment, the drive mechanism 21 is electrically connected to the central control unit 5, which includes a PLC controller. Different moving speeds can be adapted to different eyepiece discs 6 and different lenses according to actual usage needs, improving processing efficiency while ensuring dispensing accuracy.

[0029] The dispensing mechanism 22 includes a dispensing needle, and the dispensing mechanism 22 is detachably connected to the driving mechanism 21. In this embodiment, the dispensing needle is preferably made of stainless steel, and its inner diameter can be selected according to actual usage needs, without specific limitations.

[0030] like Figure 2 and Figure 3 As shown, the glue storage unit 3 is connected to the glue dispensing mechanism 22 through the delivery pipeline 30.

[0031] Specifically, in this embodiment, the glue storage unit 3 includes a glue storage container 31 and a sealing cap 32. One end of the delivery pipe 30 extends into the bottom of the glue storage container 31, and the other end is connected to the dispensing mechanism 22. The delivery pipe 30 is made of polytetrafluoroethylene (PTFE), with one end extending into the bottom of the glue storage container 31 and the other end equipped with a quick connector for connecting to the dispensing mechanism 22.

[0032] It is understandable that delivery pipes 30 with different inner diameters can be selected according to actual dispensing needs. Generally, the inner diameter of the delivery pipe 30 is larger than the inner diameter of the dispensing needle in the dispensing mechanism 22. In this embodiment, the inner diameter of the delivery pipe is set to 5-10 mm; the inner diameter of the dispensing needle is 0.2-2 mm.

[0033] like Figure 4 and Figure 5As shown, the curing unit 4 is mounted on the drive mechanism 21 and is electrically connected to the main control unit 5. The effective area of ​​the curing unit 4 covers all the preset dispensing positions of the dispensing mechanism 22 on the material carrier position 10, and the curing unit 4 maintains a preset distance from the dispensing mechanism 22 to cure the adhesive after the dispensing mechanism 22 has completed dispensing.

[0034] In this embodiment, the preset distance between the curing unit 4 and the dispensing mechanism 22 is 50-200mm. The multi-axis drive unit drives the dispensing mechanism 22 and the curing unit 4 to move along a preset trajectory in three-dimensional space. By setting the preset distance of 50-200mm between the curing unit 4 and the dispensing mechanism 22, the curing unit 4 is activated within 1-3 seconds after the dispensing mechanism 22 completes dispensing, so as to immediately cure the adhesive and reduce the contamination of the optical area of ​​the lens by the adhesive flow. This is especially suitable for the high light transmittance requirements of the lenses in vision training equipment.

[0035] As an optional implementation, it also includes an air source and an air source control unit 7. The air source control unit 7 is signal-connected to the main control unit 5; the air source is connected to the dispensing mechanism 22 via an air pipe 70 through the air source control unit 7, and the air source control unit 7 is used to control the dispensing time and air pressure.

[0036] Specifically, in this embodiment, the air source control unit 7 adjusts the dispensing time within a range of 0.1-10 seconds and the air pressure within a range of 0.1-1.2 MPa. Automated parameter adjustment is achieved through the signal connection between the air source control unit 7 and the main control unit 5, avoiding errors caused by manual intervention. The adjustable dispensing time and air pressure range can adapt to the dispensing requirements of different adhesive viscosities and different lenses, ensuring precise and controllable adhesive quantity and reducing adhesive waste or insufficiency.

[0037] As an optional implementation, the curing unit 4 is a photocuring component, and the irradiation parameters of the photocuring component are set by the central control unit 5. The irradiation parameters include irradiation time and irradiation intensity.

[0038] Optionally, in the actual dispensing and curing process, the irradiation time is adjustable from 1 to 60 seconds, and the irradiation intensity is adjustable from 10 to 100W. Adjustable irradiation parameters can be set via the central control unit 5 to allow for customization to meet the curing requirements of different types of adhesives, ensuring thorough and uniform curing and improving curing quality.

[0039] In this embodiment, the photocuring component is an ultraviolet curing lamp. Since ultraviolet light with a wavelength of 350-380nm has the highest curing efficiency for commonly used optical adhesives, the ultraviolet curing lamp in this embodiment has a wavelength range of 350-380nm, with no fewer than 10 LED beads that are evenly distributed to ensure the consistency of light intensity on the irradiated surface and reduce curing time.

[0040] Optionally, it also includes a lamp cover 8, which is disposed on the outside of the curing lamp. By providing a lamp cover, on the one hand, the curing lamp can be protected and heat dissipated, thereby improving the service life of the curing lamp; on the other hand, the irradiation area can be focused to reduce ultraviolet light leakage and improve curing efficiency.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
