AI Technical Summary
During the lens core adjustment process, the core adjustment claws are easily crushed because the core adjustment lens is not completely placed in the rear group fixture, resulting in the clamp used for core adjustment when the front and rear group fixtures are combined.
A core adjustment structure is designed, including a jaw base, a core adjustment claw, a lower disc, an XY slide table, a spring, a pressure sensor and a guide pin. The pressure sensor feedback signal is used to stop the movement of the lifting device, thereby protecting the adjustment. The core claws are prevented from being crushed.
It effectively protects the core-adjustment claw from compression, ensuring the safety and imaging quality of the lens core-adjustment process.

[0026] See also Figures 1 to 5 , the embodiment of the present application provides a lens centering machine, including a centering structure, a rear group base 2 and a front group assembly 4;
[0027] The core alignment structure includes a core alignment component 1, a lifting device for driving the core alignment component 1 to move up and down along the Z axis, and a control module; the core alignment component 1 includes a claw base 11, a core alignment claw 12, a lower plate 13, an XY slide 14, a spring 15, a pressure sensor 16, and a guide pin 17;
[0028] The lower plate 13 is fixedly arranged with the claw base 11, and the core-adjusting claw 12 is located in the gap between the lower plate 13 and the claw base 11; the guide pin 17 is arranged on the lower plate 13 and is in a vertical state, and the core-adjusting claw 12 has a corresponding first guide hole that cooperates with the guide pin 17, so that the core-adjusting claw 12 can only move along the Z axis between the lower plate 13 and the claw base 11, and the spring 15 presses between the claw base 11 and the core-adjusting claw 12, and the XY slide 14 is fixed with the claw base 11 to drive the claw base 11 to move along the X axis or the Y axis, and the lifting device is fixedly arranged with the XY slide 14;
[0029] The pressure sensor 16 is fixed on the claw base 11 and is located between the claw base 11 and the center-adjusting claw 12. The pressure sensor 16 is connected to the control module. When the center-adjusting claw 12 is pressed by the outside and overcomes the elastic force of the spring 15 to press on the pressure sensor 16, the pressure sensor 16 outputs a signal to the control module, and the control module stops the lifting device according to the signal.
[0030] The rear group base 2 is fixed on the frame and is located below the core adjustment component 1, and is used to fix the core adjustment lens 3; the front group component 4 includes a front group base 41 and a front group sensor 42, the front group base 41 is used to fix the front group sensor 42, and the front group base 41 can move up and down along the Z axis with the core adjustment component 1, so that after the front group sensor 42 moves into place, the core adjustment lens 3 can be imaged on the front group sensor 42.
[0031] Since a pressure sensor 16 is provided between the clamping claw base 11 and the centering claw 12, when the centering claw 12 is pressed against the pressure sensor 16, a signal is fed back to the control module, thereby controlling the lifting device to stop descending, thereby protecting the centering claw 12 from being crushed.
[0032] In some embodiments, the number of the springs 15 is six and they are spaced apart in the circumferential direction, the center-aligning claw 12 is provided with a groove for accommodating the elasticity, the number of the guide pins 17 is three, and the first guide hole is provided at the bottom of the groove. The lower plate 13 and the claw base 11 are fixed by bolt connection.
[0033] In some embodiments, a buffer pad 18 is further provided between the pressure sensor 16 and the claw base 11. The buffer pad 18 may be made of silicone material.
[0034] In some embodiments, the pressure sensor is a piezoelectric ceramic.
[0035] In some embodiments, a support member 43 is further fixedly provided on the front group base 41, and the support member 43 is used to separate the front group base 41 and the rear group base 2 by a preset distance. The lower part of the support member 43 has a connecting column 431, and the upper end of the connecting column 431 is provided with a first supporting platform 432. The core-adjusting claw 12 is provided with a first through hole 121 for facilitating the connecting column 431 to pass downward, and the first supporting platform 432 abuts against the core-adjusting claw 12, so that the core-adjusting claw 12 can drive the front group assembly 4 to move up and down together during the lifting process;

[0037] The inner diameter of the first through hole 121 is larger than the outer diameter of the positioning column 433 , so that after the front group assembly 4 is combined with the rear group base 2 , the center aligning claw 12 does not contact the positioning column 433 when moving along the X-axis or the Y-axis.
[0038] In some embodiments, a UV curing lamp 5 is also fixedly mounted on the jaw base 11 .
[0039] The following briefly describes the working process of a lens alignment machine in the above embodiment:
[0040] First, the core-adjusting lens 3 is placed on the rear group base 2, and the lifting device drives the entire core-adjusting assembly 1 and the front group assembly 4 to descend together. The front group assembly 4 is combined with the rear group base 2, and the positioning column 433 of the support member 43 is inserted into the second positioning hole 21 of the rear group base 2. The second support platform 434 abuts against the rear group base 2. At this time, the front group assembly 4 and the rear group base 2 remain stationary, and the core-adjusting lens 3 can be imaged on the front group sensor 42 of the front group assembly 4, and the core-adjusting claw 12 presses on the lens of the core-adjusting lens 3. During the descent of the core-adjusting claw 12, if the core-adjusting lens 3 is not completely placed in the rear group base 2, the core-adjusting lens 3 will press the core-adjusting claw 12, so that the core-adjusting claw 12 presses on the piezoelectric ceramic piece, and the piezoelectric ceramic piece outputs current under pressure. The control module controls the movement of the lifting device to cut off according to the current signal, which plays a protective role.
[0041] During the alignment process, the alignment claw 12 is subjected to the elastic force of the spring 15, so the alignment claw 12 can be pressed on the lens with a stable pressure. According to the imaging condition of the front group sensor 42, the XY slide 14 drives the claw base 11 and the alignment claw 12 therein to move, thereby driving the lens to move relative to the frame, so as to perform alignment. After the lens alignment is completed, the UV curing lamp 5 is started to cure the UV light curing glue on the lens by ultraviolet irradiation, so that the lens and the frame are fixed. After the lens is cured, the lifting device drives the alignment assembly 1 and the front group assembly 4 to rise together, and the front group assembly 4 is separated from the rear group base 2.
