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] See also Figure 1-5 The utility model provides a technical solution: a jig for accurately positioning and assembling circular lenses, comprising a base 1, a receiving groove 2 being provided on the top surface of the base 1, a positioning tube 3 being integrally formed on the base 1 and located at the bottom side of the receiving groove 2, a groove 5 being provided on the bottom surface of the base 1 and located directly below the positioning tube 3; a slide groove 4 being provided on both side walls of the groove 5, and the slide groove 4 being conductively connected to the bottom end of the positioning tube 3 through a connecting hole 14, an ejection assembly being inserted into the inner cavity of the positioning tube 3, and the bottom end of the ejection assembly extending to the slide groove 4, a pressing plate 10 being provided in the inner cavity of the groove 5;

[0026] When the lens needs to be assembled, the staff first installs the product in the receiving groove 2 of the base 1, so that the receiving groove 2 can engage and limit the product. Since a groove 5 and two slide grooves 4 are provided on the bottom surface of the base 1 and directly below the positioning tube 3, and the slide groove 4 is connected to the bottom end of the positioning tube 3 through the connecting hole 14, and the inner cavity of the positioning tube 3 is plugged with an ejection assembly, and the bottom end of the ejection assembly extends to the slide groove 4, the ejection assembly can be flexibly extended and retracted in the connecting hole 14 and the two slide grooves 4. Then the staff puts the groove of the lens on the ejection assembly in the positioning tube 3, and then presses the lens down until the lens fits into the lens position on the product surface. Finally, release your fingers and pick up the product to complete the lens assembly. Through the pressure plate 10, it can be installed in the inner cavity of the groove 5 and limit the ejection assembly, thereby improving the stability of the ejection assembly.

[0027] See Figure 1 、 Figure 3-Figure 5The ejection assembly includes a movable core 6, which is inserted into the inner cavity of the positioning tube 3. The bottom ends of both sides of the movable core 6 are integrally formed with anti-slip blocks 7 for sliding in the slide groove 4; the bottom end of the movable core 6 is provided with a card slot 8, and the inner cavity of the card slot 8 is inserted with a spring 9, and the bottom end of the spring 9 is connected to the pressure plate 10. There are two card slots 8, and the two card slots 8 are symmetrically distributed on the left and right.

[0028] The movable core 6 in the ejection assembly can be inserted into the inner cavity of the positioning tube 3, and the bottom end of the positioning tube 3 can pass through the connecting hole 14 and extend to the slide groove 4. At the same time, it can provide space for the two card slots 8. Since the inner cavities of the two card slots 8 are both inserted with springs 9, the two springs 9 can provide upward elastic force to the movable core 6, so that the movable core 6 can slide up and down flexibly in the inner cavities of the positioning tube 3 and the connecting hole 14, and eject the completed lens assembled product. Since the bottom ends of both sides of the movable core 6 are integrally formed with anti-slip blocks 7 for sliding in the slide groove 4, the movable core 6 can not only move up and down smoothly, but also prevent the movable core 6 from sliding out of the positioning tube 3 and the connecting hole 14.

[0029] See Figure 3-Figure 5 The inner diameter of the positioning tube 3 and the inner diameter of the communicating hole 14 are the same as the outer diameter of the movable core 6, so that the movable core 6 can slide smoothly and flexibly in the positioning tube 3 and the communicating hole 14.

[0032] See Figure 1-Figure 3 , a first notch 12 is formed on the top of both side walls of the base 1, and the first notch 12 is connected to the receiving groove 2;

[0033] The two first notches 12 make it convenient for workers to take the assembled product out of the receiving tank 2 .

[0034] See Figure 1-Figure 3 The bottom of the other two side walls of the base 1 are each provided with a second notch 13, which makes it convenient for the staff to hold the base 1 steadily.

[0035] During work, when the lens needs to be assembled, the staff first installs the product in the receiving groove 2 of the base 1, so that the receiving groove 2 can engage and limit the product. Since a groove 5 and two slide grooves 4 are provided on the bottom surface of the base 1 and directly below the positioning tube 3, and the slide groove 4 is connected to the bottom end of the positioning tube 3 through the connecting hole 14, and the inner cavity of the positioning tube 3 is plugged with an ejection assembly, and the bottom end of the ejection assembly extends to the slide groove 4, the ejection assembly can be flexibly extended and retracted in the connecting hole 14 and the two slide grooves 4. Then the staff puts the groove of the lens on the ejection assembly in the positioning tube 3, and then presses the lens down until the lens fits into the lens position on the product surface. Finally, release your fingers and pick up the product to complete the lens assembly. Through the pressure plate 10, it can be installed in the inner cavity of the groove 5 and limit the ejection assembly, thereby improving the stability of the ejection assembly.

[0036] The movable core 6 in the ejection assembly can be inserted into the inner cavity of the positioning tube 3, and the bottom end of the positioning tube 3 can pass through the connecting hole 14 and extend to the slide groove 4. At the same time, it can provide space for the two card slots 8.

Since the bottom ends of both sides of the movable core 6 are integrally formed with anti-slip blocks 7 for sliding in the slide groove 4, the movable core 6 can not only move up and down smoothly, but also prevent the movable core 6 from sliding out of the positioning tube 3 and the connecting hole 14.

[0037] The pressure plate 10 can be fixed in the groove 5 of the base 1 by four fixing screws 11, which makes it convenient for the staff to disassemble and assemble the pressure plate 10. The two first notches 12 can facilitate the staff to take the assembled product out of the receiving groove 2. Since the bottom of the other two side walls of the base 1 are provided with second notches 13, it is convenient for the staff to hold the base 1 steadily.

[0038] In summary, the device can provide great convenience in product production and assembly.
