Description

Technical Field

[0001] The utility model relates to the technical field of corneal contact lens transfer, in particular to a contact lens transfer device for testing. Background Art

[0002] Contact lenses, a key achievement in modern ophthalmic medical technology, stem from the demand for improved vision correction methods, particularly for those seeking a more natural appearance, increased comfort, and convenience. Advances in materials science have led to the evolution of contact lenses from their original rigid plastics to today's soft hydrogel and silicone hydrogel materials, offering improved breathability and comfort.

[0003] Most existing contact lens implants are performed manually. Inefficiency is a significant issue during this process, as manual operation is limited in speed and continuous working time. This is particularly evident when faced with large-scale production demands. Furthermore, insufficient operational accuracy is a key issue. Because manual operation relies on the operator's skill and concentration, long hours of work can lead to fatigue, increasing the error rate and affecting the accuracy of contact lens positioning and handling. This inaccuracy not only affects production efficiency but can also lead to product quality issues and increase the cost of subsequent inspection and rework. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a contact lens detection transfer device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A transfer device for contact lens testing includes two conveying devices and a support base. The support base is located between the two conveying devices. The upper end of the support base is rotatably connected to a turntable. The upper end of the turntable is fixedly connected to a column. The upper end of the column is fixedly connected to a support frame. The other end of the support frame is fixedly connected to an electric telescopic rod below. The telescopic end of the electric telescopic rod is connected to an adsorption component. Both conveying devices are provided with a placement box, and the two placement boxes are respectively clamped to one conveying device through a limit assembly.

[0007] As a further improvement of the present invention, a servo motor is installed at the lower end of the support seat, and the output shaft end of the servo motor passes through the support seat and is fixedly connected to the turntable.

[0008] As a further improvement of the present invention, the adsorption assembly includes a fixed frame fixedly connected to the telescopic end of the electric telescopic rod, a chamber is provided inside the fixed frame, an air pump connected to the chamber is installed at the upper end of the fixed frame, a piston plate is slidingly provided in the chamber, and a plurality of straws connected to the chamber are installed at the lower end of the fixed frame.

[0009] As a further improvement of the present invention, the limiting assembly includes limiting blocks arranged on the front and rear sides of the placement box, and the two limiting blocks are fixedly connected to the conveying device. Limiting bars are provided on the left and right sides of the placement box, and the two limiting bars are fixedly connected to the conveying device.

[0010] As a further improvement of the present invention, a plurality of fixing grooves are provided on the upper ends of the two placement boxes, and corneal contact lenses are provided in the plurality of fixing grooves on one of the placement boxes.

[0011] As a further improvement of the present invention, the straws are the same in size and number as the fixing grooves.

[0012] Beneficial effects of the utility model:

[0013] By setting the limit assembly and the placement box, the placement box can be limited by the cooperation of the limit bar and the limit block. At the same time, due to the special structure of the limit bar and the limit block, the placement box can be well limited without affecting the normal operation of the conveying device, thereby improving the accuracy of automation.

[0014] By setting up an adsorption component and starting the air pump to extract the gas in the chamber, the piston plate will move upward under the action of air pressure, so that multiple straws can use air pressure to adsorb the corneal contact lenses. In conjunction with the turntable driven by the servo motor, multiple corneal contact lenses can be quickly adsorbed and automated transplantation can be completed, which can improve work efficiency.

[0015] The utility model realizes the precise positioning of the placement box and improves the detection and transplantation efficiency of corneal contact lenses through the cooperation of air pressure adsorption and servo motor drive. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Figures 1-4 A contact lens detection transfer device comprises two conveying devices 1 and a support base 2 arranged on the left and right. The support base 2 is located between the two conveying devices 1. The upper end of the support base 2 is rotatably connected to a turntable 4 through a rotating shaft. A servo motor 6 for driving the turntable 4 is installed at the lower end of the support base 2. The output shaft end of the servo motor 6 passes through the support base 2 and is fixedly connected to the turntable 4. The upper end of the turntable 4 is fixedly connected to a supporting column 7 by bolts. The upper end of the column 7 is fixedly connected to a support frame 8 by bolts. The other end of the support frame 8 is fixedly connected to an electric telescopic rod 9 by bolts. The telescopic end of the electric telescopic rod 9 is connected to a suction The attached component, the adsorption component includes a fixed frame 10 fixedly connected to the telescopic end of the electric telescopic rod 9 by bolts, and a chamber 12 is provided inside the fixed frame 10, and the chamber 12 is used to control the internal air pressure. The upper end of the fixed frame 10 is equipped with an air pump 11 connected to the chamber 12, and the air pump 11 is used to extract the internal gas of the chamber 12. A piston plate 13 is slidingly provided in the chamber 12, and the contact part of the piston plate 13 and the chamber 12 is provided with a sealing strip. The plane size of the piston plate 13 is the same as the plane size of the chamber 12. The lower end of the fixed frame 10 is equipped with a plurality of straws 14 connected to the chamber 12, and the straws 14 are made of soft rubber material.

[0023] Both conveying devices 1 are provided with a placement box 15 for storing corneal contact lenses 17. The upper ends of the two placement boxes 15 are provided with fixing grooves 16 of the same size and number as the straws 14. Each straw 14 can be inserted into a fixing groove 16. A corneal contact lens 17 is provided in multiple fixing grooves 16 on one of the placement boxes 15. The two placement boxes 15 are respectively connected to a conveying device 1 through a limiting assembly. The limiting assembly includes limiting blocks 3 arranged on the front and rear sides of the placement box 15. The two limiting blocks 3 are fixedly connected to the conveying device 1 by bolts. Limiting bars 5 are provided on the left and right sides of the placement box 15. The two limiting bars 5 are fixedly connected to the conveying device 1 by bolts.

[0024] When the present invention is used, a worker first places a placement box 15 containing a contact lens 17 on a conveyor 1, and two limit blocks 3 and two limit bars 5 will clamp the placement box 15. Another empty placement box 15 is also placed on another conveyor 1. Then, the electric telescopic rod 9 is started to drive the fixed frame 10 to move down to a certain position. Then, multiple straws 14 are respectively inserted into multiple fixed grooves 16. Multiple straws 14 will contact the contact lenses 17. Then, the air pump 11 is started to extract the gas in the chamber 12. The piston plate 13 will move up under the action of air pressure, so that the multiple straws 14 will adsorb the contact lenses 17. Then, the electric telescopic rod 9 is started to fix the frame 10. After reset, multiple contact lenses 17 are separated from the fixed grooves 16 together with the upward movement of multiple straws 14. Then, the servo motor 6 is started to drive the turntable 4 to rotate. The rotation of the turntable 4 will drive the column 7 to rotate. The rotation of the column 7 will drive the support frame 8 to rotate. The rotation of the support frame 8 will drive the fixed frame 10 to rotate, indirectly driving the multiple contact lenses 17 to rotate to the top of another placement box 15. Then, the electric telescopic rod 9 is started again to move the multiple straws 14 downward and reinsert them into the fixed grooves 16. The air pump 11 is started again to fill gas into the chamber 12, driving the piston plate 13 to move downward, so that the straws 14 no longer have adsorption force, and the multiple contact lenses 17 will fall into the multiple fixed grooves 16, completing the transplantation.

[0025] It should be noted that during the transplantation process, the stage where the suction tube 14 adsorbs the corneal contact lens 17 can be used to test the integrity of the corneal contact lens 17 to a certain extent. When the integrity of the corneal contact lens 17 is insufficient, the suction tube 14 cannot adsorb the corneal contact lens 17 through air pressure.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
