Detailed implementation manners

[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the illustrated embodiments are not intended to limit the present utility model.

[0028] Refer to Figure 1 and Figure 2 As shown, the present utility model discloses a locking device, including two locking units 10 arranged relatively at intervals along the first direction D1 to fix the to-be-locked member through the locking unit 10. In this embodiment, the to-be-locked member is a material frame for receiving lenses.

[0029] The locking unit 10 includes a support base 11, a limiting seat 12 and a pressing member 13. The support base 11 is used to support the material frame and install the remaining components. The support base 11 extends along the second direction D2, and a support surface 111 is provided on the support base 11, and the material frame during operation is arranged on the support surface 111. Preferably, the second direction D2 is perpendicular to the first direction D1.

[0030] The limiting seat 12 is used to cooperate with the support base 11 to limit the material frame. The limiting seat 12 is arranged on the support surface 111, and the limiting seat 12 includes a connected first limiting member 121 and a second limiting member 122. The first limiting member 121 extends along the second direction D2. Taking a plane perpendicular to the second direction D2 to intercept the first limiting member 121 and the support base 11, its cross-section is in a similar "L" shape structure to carry and limit the material frame. A notch portion 1211 is formed on the first limiting member 121 to facilitate the pressing member 13 to achieve pressing. Those skilled in the art can set the number and positions of the notch portion 1211 and the pressing member 13 according to actual needs; preferably, both are provided with a plurality of them and are arranged at intervals in sequence along the second direction D2 to achieve a good pressing and fixing effect.

[0031] The second limiting member 122 is disposed at one end of the first limiting member 121 along the second direction D2. The second limiting member 122 and the first limiting member 121 form an "L"-shaped structure, so that the second limiting member 122 forms a limit when the material frame moves along the second direction D2 toward the side where the second limiting member 122 is located. A limited space 123 is formed between the two limiting seats 12 opposite to each other along the first direction D1, and the limited space 123 is used to accommodate the material frame.

[0032] The pressing member 13 is used to cooperate with the support seat 11 and the limiting seat 12 to achieve locking and fixing of the material frame. The pressing member 13 is arranged on the side of the support seat 11 away from the other support seat 11 along the first direction D1 to avoid interfering with the material frame entering the limiting space 123 and avoiding interfering with other devices to take and place lenses. The pressing member 13 is configured to be able to switch between a pressing state and a loose state.

[0033] When in the clamped state, the clamping member 13 clamps the material frame in the limiting space 123 from the notch portion 1211. At this time, the material frame is locked and positioned by the clamping member 13, the support member and the limiting seat 12. During the operation, the material frame can be effectively prevented from shaking or falling off, thereby improving the stability and safety of the material frame and ensuring high quality and yield in the lens production process. When in the loosened state, the material frame in the limiting space 123 can move along the second direction D2 toward the side away from the second limiting member 122 to take, place and replace the material frame. Those skilled in the art can set the clamping member 13 according to actual needs. For example, a tilted telescopic cylinder is set to achieve the clamping of the material frame.

[0034] Taking the unloading of lenses as an example, an empty material frame is placed in the limiting space 123, so that the material frame is placed on the support surface 111 and one end of the material frame along the second direction D2 abuts against the second limiting member 122. Subsequently, the state of the pressing member 13 is switched so that the pressing member 13 presses the material frame. After pressing, the lenses can be placed in the material frame one by one. When the material frame is full of lenses, the state of the pressing member 13 is switched so that the pressing member 13 releases the material frame. Finally, the material frame is removed to complete one unloading.

[0035] The locking device of the utility model conveniently and effectively realizes the locking and positioning of the material frame by setting the support seat 11, the limit seat 12 and the pressing member 13 to cooperate with each other. During the operation, it can effectively prevent the material frame from shaking and falling off, improve the stability and safety of the material frame, and ensure high quality and yield in the lens production process.

[0036] Reference Figure 2As shown, in some embodiments of the locking device of the present utility model, a limiting portion 1111 is provided on the supporting surface 111. By providing the limiting portion 1111, when the pressing member 13 does not press the material frame, the pre-positioning of the material frame can be achieved with the limiting portion 1111.
