DETAILED DESCRIPTION

[0024] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model provides a technical solution: a contact lens filling workbench 2, comprising a base 1 and a workbench 2 fixed above the base 1, a micro motor 7 is provided at the bottom end of the workbench 2, the output shaft of the micro motor 7 is fixedly connected to a threaded rod 8, a threaded block 9 is threadedly connected to the surface of the threaded rod 8, a fixed plate 10 is fixed to the bottom end of the threaded block 9, and a filling head 11 is fixed on the fixed plate 10, a groove 5 is opened in the workbench 2, a roller 4 is provided at the bottom end of the workbench 2, and the rollers 4 are evenly arranged horizontally, a glasses box 3 is provided above the roller 4 inside the groove 5, a squeezing mechanism 6 is provided above the workbench 2, and the squeezing mechanism 6 is located between two adjacent glasses boxes 3.

[0026] The above technical solution uses a micro motor 7, a threaded rod 8 and a threaded block 9 to drive the fixed plate 10 and the injection head 11 to move upward to realize the injection operation. The use of the injection head 11 to inject liquid vertically upward can also avoid liquid dripping. The squeezing mechanism 6 is set behind the two glasses boxes 3 to make the moving glasses boxes 3 evenly distributed on both sides of the squeezing mechanism 6, thereby achieving a positioning effect and facilitating the subsequent injection operation.

[0027] Specifically, such as Figure 5As shown, the extrusion mechanism 6 includes a fixed frame 601, a guide wheel 602, a movable block 603, a limit block 604, a limit slot 605 and a spring 606. The fixed frame 601 is fixed on the workbench 2 respectively. The movable block 603 is provided in the fixed frame 601. The opposite surface of the movable block 603 is movably provided with a guide wheel 602 through a pin shaft. A spring 606 is provided above the movable block 603, and the other end of the spring 606 is fixed to the fixed frame 601. A limit slot 605 is provided in the fixed frame 601, and a limit block 604 is provided in the limit slot 605. The opposite surface of the limit block 604 is fixed to the surface of the movable block 603.

[0028] The above scheme uses the squeezing mechanism 6 to utilize the elastic force of the spring 606 to lift the guide wheel 602 upward when the glasses box 3 moves, and at the same time, it can also use the elastic force to move the guide wheel 602 downward and stop it between the two glasses boxes 3, thereby realizing the limiting operation. The limiting groove 605 and the limiting block 604 can cooperate with the movable block 603 to move up and down with the guide wheel 602, thereby improving the stability of the movement of the glasses box 3 and making the glasses box 3 move more smoothly.

[0029] Specifically, such as Figure 3 As shown, a slide groove 12 is provided in the base 1, a slider 14 is provided inside the slide groove 12, and the slider 14 is fixed to the side of the fixed plate 10. A connecting pipe 13 is provided at the bottom end of the fixed plate 10, and the connecting pipe 13 passes through the fixed plate 10 and is connected to the injection head 11.

[0030] Specifically, such as Figure 4 As shown, the glasses case 3 includes an upper shell 301, a lower shell 302 and a seal 303. The upper shell 301 and the lower shell 302 are connected by threads. An internally connected seal 303 is provided at the center of the bottom end of the lower shell 302. The glasses case 3 is vertically located directly above the liquid injection head 11 under the action of the squeezing mechanism 6.

[0031] The above solution provides a seal 303 inside the lower shell 302 of the glasses case 3, which makes it easy to insert the liquid injection head 11 into the lower shell 302 for injection. When pulling it out, the surface of the liquid injection head 11 can be squeezed to avoid liquid remaining on the surface of the liquid injection head 11, thereby preventing liquid from leaking out of the liquid injection head 11.

[0032] Working principle: When in use, multiple glasses boxes 3 are placed in the groove 5 in the workbench 2 and gradually pushed forward by multiple groups of rollers 4, so that multiple glasses boxes 3 are arranged in the workbench 2, and the guide wheel 602 in the squeezing mechanism 6 will use the pressure of the spring 606 to squeeze downward between the two glasses boxes 3. After the multiple glasses boxes 3 are arranged, start the micro motor 7 to drive the threaded block 9 and the fixed plate 10 below to move upward through the threaded rod 8. While the fixed plate 10 moves, the injection head 11 on the surface will be inserted into the lower shell 302 through the seal 303 of the lower shell 302 of the glasses box 3, and the contact lens liquid that needs to be injected will be injected into the interior of the glasses box 3 through the connecting pipe 13 through the injection head 11. After the injection is completed, the micro motor 7 reverses and separates the injection head 11 and the glasses box 3 through the fixed plate 10, and the empty glasses box 3 is loaded again and the injected glasses box 3 is pushed out through the roller 4.
