Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: A lens assembly device for producing an optical lens, such as Figure 1-4As shown, it includes a base 1, which is a supporting component, made of a harder metal material, customized according to the size of the device, directly in contact with the bottom plate, and transmitting the supporting force of the bracket to the mounting bottom plate outside the device; a fixing frame 2, welded to the rear of the base 1; a cylinder 3, fixedly installed on the top of the fixing frame 2, providing downward pressure for the lens installation, and the telescopic rod of the cylinder 3 penetrates the fixing frame 2; a pressure block 4, fixedly connected to the lower part of the telescopic rod of the cylinder 3, moves with the movement of the telescopic rod of the cylinder 3, and contacts with the upper surface of the lens when assembling the optical lens, and evenly distributes the downward pressure on the lens; a mounting seat 5, fixedly connected to the inside of the base 1, and used for installation and Protect the components that provide power; the motor 51 is installed on the inner side of the mounting base 5 to provide rotational power. The motor can stop in time after rotating at a small angle; the turntable 6 is fixedly connected to the upper part of the output shaft of the motor 51, and rotates with the output shaft of the motor 51, serving as a transmission component of the motor power; the pad 7 is fixedly installed on the top of the turntable 6, and is used to place the lens barrel required for the optical lens to be assembled. The pad 7 and the pressure block 4 are in a concentric position with a common center, and rotate with the rotation of the motor; the clamping block 8 is symmetrically slidably arranged on the pad 7, and is used to clamp and stabilize the lens when the lens is assembled, and the bottom of the clamping block 8 is in sliding contact with the turntable 6.

[0021] When assembling the lens, first, pull the two clamping blocks 8 apart toward the left and right sides, then place the lens barrel of the optical lens vertically upward and centered at the center point of the cushion block 7. At this time, the lens barrel is located between the two clamping blocks 8 on the cushion block 7, and the opening of the lens barrel is in a concentric position with the pressing block 4 above. Subsequently, slide the clamping blocks 8 on both sides inward toward each other, so that the two clamping blocks 8 clamp the inner lens barrel, and the lens barrel is supported and stabilized by the clamping blocks 8. After the two clamping blocks 8 clamp the lens barrel, put the lens to be assembled into the lens barrel, and control the cylinder 3 to extend the telescopic rod downward, and the telescopic rod drives the pressing block 4 to move downward, so that the pressing block 4 extends into the lens barrel and meets the required The installed lens surface contacts and firmly presses the lens on the lens barrel. Then, the telescopic rod of the cylinder 3 is controlled to be retracted upward, and then the motor 51 is started and controlled to rotate a certain angle. The turntable 6 and the cushion block 7 are driven to rotate by the rotation of the motor 51, and the lens barrel on the cushion block 7 rotates synchronously with the cushion block 7. After the motor 51 stops rotating, the cylinder 3 is continued to be controlled to extend the telescopic rod to press the lens for the second time. The telescopic rod of the cylinder 3 drives the pressure block 4 to press the lens installed on the lens barrel, and the motor 51 drives the lens barrel to rotate an angle. The pressure block 4 is pressed down for multiple times to press the lens, so as to ensure the parallelism and stability of the lens installation and improve the assembly quality.

[0022] Embodiment 2: Based on embodiment 1, Figure 1-4As shown, it also includes a connecting rod 9, and the clamping block 8 is rotatably provided with a connecting rod 9, and the two connecting rods 9 are cross-hinged with each other; a fixed block 91, which is fixedly connected to the rear side of the top of the turntable 6 for connection and support, and the front of the fixed block 91 penetrates into the two connecting rods 9 and is in rotatable contact with the two connecting rods 9; a spring 10, a spring 10 is wound around the outer side of the front of the fixed block 91, and the other end of the spring 10 is connected to the connecting rod 9 at the rear side, and the spring is a torsion spring, which will be in a deformation and force storage state when it is rotated and twisted; a top block 12, which is slidably arranged on the inner side of the cushion block 7, when the lens is assembled , the top of the top block 12 will contact one end of the lens barrel; the connecting block 13 is welded to the upper inner side of the top block 12, the outer lower side of the connecting block 13 contacts the inner sides of the two connecting rods 9, the lower part of the connecting block 13 is circular, when the circular block at the lower part of the connecting block 13 is close to the hinge point between the connecting rods 9, the connecting rods 9 will be opened by the connecting block 13, and the upper parts of the two connecting rods 9 will move away from each other, and vice versa, when the circular block at the lower part of the connecting block 13 is away from the hinge point between the connecting rods 9, the upper parts of the two connecting rods will move closer to each other; the rotating rod 11 is rotatably arranged on the inner side of the front part of the cushion block 7, and the rear part is in sliding contact with the inner side of the connecting block 13.

[0023] Initially, the top of the top block 12 is higher than the top of the cushion block 7, and the lower part of the connecting block 13 is located between the two connecting rods 9 and close to the hinge point of the two connecting rods 9. Under the action of the connecting block 13, the two connecting rods 9 rotate and open in opposite directions. The left and right clamping blocks 8 respectively connected to the upper parts of the two connecting rods 9 are in the state of the connecting rod 9 being opened. The spring 10 is in a state of twisting and storing force due to the rotation of the rear connecting rod 9, and is in a state of being opened in opposite directions. The rear part of the rotating rod 11 is located on the inner side of the connecting block 13 and will rotate with the movement of the connecting block 13. Conversely, the rotating rod 11 can be rotated to lift the connecting block 13. When it is necessary to install a lens on the lens barrel, first, a section of the lens barrel is pressed against the top of the top block 12 and pressed downward so that the lower end of the lens barrel contacts the cushion block 7. The top block 12 moves downward under the force, driving the connecting block 13 to move downward, and the connecting The block 13 is far away from the hinge point of the two connecting rods 9, but still keeps in contact with the inner sides of the two connecting rods 9. Under the action of the spring 10, the connecting rod 9 is forced to rotate back inward. Synchronously, the two clamping blocks 8 connected to the connecting rod 9 are clamped inwardly under the drive of the connecting rod 9. The two clamping blocks 8 clamp the lens barrel on the cushion block 7. When the lens is installed, the connecting block 13 is pried up by pressing the front position of the rotating rod 11 downward. The connecting block 13 pushes the top block 12 to lift up. At the same time, the connecting block 13 is close to the hinge point of the two connecting rods 9 to rotate and spread the two connecting rods 9. The connecting rod 9 drives the clamping blocks 8 to open inward and break away from the lens barrel. The lens barrel can be quickly clamped and released by the connecting rod 9, the connecting block 13, the rotating rod 11 and other components. There is no need to manually move the clamping blocks 8, which is more convenient.

At the same time, the lower part of the step drawing during installation can be placed in the groove of the drawing frame 15, so that the back side of the drawing is flat on the rotating plate 23, and the rotating block 14 is rotated to fix the upper part of the drawing. By placing the drawing on the drawing frame 15, people can quickly compare and view the drawing placed flat on the rotating plate 23 when assembling the lens, thereby reducing mistakes in the installation steps.
