[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As shown in the utility model provides a kind of optical lens carrier plate's clamping mechanism, mainly used for processing optical lens carrier plate when to optical lens carrier plate clamping movement use, can replace artificial feeding and discharging operation. Figs. 1-3

[0025] The specific structure of the clamping mechanism mainly includes a dustproof shell 1, two clamping arm plates 3 are installed inside the dustproof shell 1 through linear guide rails 2, so that the clamping arm plates 3 can move along the length direction of the linear guide rails 2. Among them, the number of linear guide rails 2 provided for the movement of the clamping arm plates 3 is two, and the two linear guide rails 2 are fixed on both sides inside the dustproof shell 1, and when connected, each clamping arm plate 3 is connected with two linear guide rails 2 at the same time, to improve the stability of movement. In addition, two sliders 8 for moving on the linear guide rails 2 are also provided on each clamping arm plate 3, and the clamping arm plates 3 are driven to move by the sliders 8 moving on the linear guide rails 2.

[0026] To drive and control the movement of the two clamping arm plates 3 on the two linear guide rails 2, a lead screw adjusting assembly 4 for controlling the movement of the two clamping arm plates 3 is installed on one side of the dustproof shell 1, and after the lead screw adjusting assembly 4 is controlled, the two clamping arm plates 3 will move in opposite directions at the same time, and finally form a structure for clamping or opening. When in the clamping structure state, it can be used for clamping optical lens carrier plate to move; when in the open structure state, it can be used for adjusting position to prepare clamping or opening operation.

[0027] ​The structure of the screw rod adjusting assembly 4 mainly comprises a stepper motor 401, a screw rod 402 and screw rod connecting pieces 403. The screw rod connecting pieces 403 are provided in two numbers and are reversely distributed, and the two screw rod connecting pieces 403 are connected to different clamping arm plates 3 respectively. One end of the screw rod 402 is connected to the output end of the stepper motor 401, and the other end of the screw rod 402 penetrates through the two screw rod connecting pieces 403 simultaneously. In this case, when the screw rod 402 rotates, it can drive the two screw rod connecting pieces 403 to move in different directions, so as to make the two clamping arm plates 3 move in opposite directions. Specifically, when the stepper motor 401 reversely rotates, the two screw rod connecting pieces 403 drive the two clamping arm plates 3 to move away from each other to form an open structure. When the stepper motor 401 rotates forward, the two screw rod connecting pieces 403 drive the two clamping arm plates 3 to move close to each other to form a clamping structure.

[0028] In order to enable the two clamping arm plates 3 to be opened to a certain distance without affecting clamping, the side of the dustproof shell 1 is also provided with a displacement sensor 5 for detecting the clamping arm plate 3, which is greater than the length of the optical lens carrier after being opened as required. When the displacement sensor 5 detects the position of the clamping arm plate 3, it represents that the clamping arm plate 3 has been opened to a distance that satisfies the clamping of the optical lens carrier. At this time, the two clamping arm plates 3 do not need to be continuously opened, and wait for the operation of clamping the optical lens carrier.

[0029] The position of the clamping arm plate 3 clamping the optical lens carrier is arranged at the bottom, so the bottom of the clamping arm plate 3 needs to penetrate through the bottom of the dustproof shell 1 and extend downward, and is connected with two clamping pieces 6 for clamping the optical lens carrier. The two clamping pieces 6 arranged on the same clamping arm plate 3 are distributed in the same direction, and the clamping pieces 6 arranged on different clamping arm plates 3 are symmetrically distributed.

[0030] The structure of the clamping piece 6 comprises a clamping jaw 601 and an air cylinder 602. The clamping jaw 601 is mounted on the bottom of the clamping arm plate 3, and the air cylinder 602 is mounted on one side of the clamping jaw 601 through an air cylinder mounting block 603. An inwardly bent clamping portion 6011 is arranged at the end of the clamping jaw 601 away from the clamping arm plate 3, which is convenient for clamping the optical lens carrier. Correspondingly, the air cylinder 602 mounted on the clamping jaw 601 can also extend to the end of the clamping portion 6011, and cooperates with the clamping portion 6011 to fix the optical lens carrier. It should be noted that when the clamping portion 6011 is arranged at the bottom of the optical lens carrier, the air cylinder 602 is arranged at the top of the optical lens carrier.

[0031] When the clamping jaw 601 clamps the optical lens carrier, a carrier sensor 7 for detecting the clamping state of the optical lens carrier is also mounted on the clamping jaw 601. The number of the carrier sensor 7 is two, and the carrier sensor 7 is mounted on the outer side of the clamping jaw 601 of different clamping arm plates 3. When the clamping piece 6 completes the clamping action,

[0032] Before clamping the optical lens carrier plate, the position of the optical lens carrier plate can be detected by the carrier plate sensor 7, and then the clamping operation is performed. The carrier plate sensor 7 detects the state of clamping the optical lens carrier plate, and when the clamping is completed, the lifting processing conveying is facilitated.

[0033] The top plate 9 is connected to the top of the dustproof shell 1, and the top plate 9 is provided with a connecting part 901 for mounting the lifting cylinder 602. With the connecting part 901 mounted with the lifting cylinder for lifting, the optical lens carrier plate can be conveyed in cooperation with the clamping operation.

[0034] In addition, the plastic five-way 10 for shunting the gas supply is also mounted on the top plate 9. The plastic five-way 10 includes one inlet and four outlets, and the four outlets are respectively connected to the four cylinders 602 on the clamping jaw 601. The gas is input through the inlet, and then is provided to the four cylinders 602 through the four outlets after being shunted.

[0035] Compared with the conventional technology, the clamping mechanism provided by the technical scheme drives the clamping piece 6 to move in different directions through the screw rod adjusting assembly 4, completely clamps the optical lens carrier plate, and automatically carries out the loading and unloading operation. The whole process does not need manual participation, avoids the case of artificial damage or secondary pollution, and improves the work efficiency. At the same time, the clamping mechanism is provided with components such as the displacement sensor 5 and the carrier plate sensor 7, which effectively detects the state in the process of taking and placing the optical lens carrier plate, and avoids the case of dropping the piece due to not clamping in place.

[0036] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
