Specifically, as shown in fig. 2, the plane adjustment assembly 10 is provided with a bearing seat 131 for respectively accommodating the calibration member and the lens barrel 200, the plane adjustment assembly 10 is further provided with a detection member 111 for respectively acquiring outer diameter information of the calibration member and outer diameter information of the lens barrel 200, as shown in fig. 3, the triaxial adjustment assembly 20 is provided with a suction member 243 for sucking lenses, as shown in fig. 1, the optical center detector 30 is respectively arranged corresponding to the bearing seat 131 and the suction member 243 for acquiring first optical center information of the calibration member and second optical center information of the lenses.

The lens aligning device 100 can make the lenses in the lens module meet the set tolerance value of the same optical axis when being assembled, thereby avoiding the problems of overhigh maintenance cost, possible scratching and even scrapping of the lenses and the like caused by the deviation and the need of reassembly.

As shown in fig. 1 to 4, when the lens module is assembled by using the lens aligning device 100, in a first step, the calibration piece may be first accommodated in the bearing seat 131 (by means of a manipulator or the like), the calibration piece is detected by the optical center detector 30 to obtain first optical center information of the calibration piece and transmit the first optical center information to the controller 40, and meanwhile, outer diameter information of the calibration piece is obtained by the detection piece 111 and transmitted to the controller 40; secondly, the calibration piece is taken away (by means of a manipulator and the like), then the lens barrel 200 is accommodated in the bearing seat 131 (by means of a manipulator and the like), and the outer diameter information of the lens barrel 200 is acquired by the detection piece 111 and is transmitted to the controller 40; thirdly, the lens is sucked by the sucking member 243 on the triaxial adjusting assembly 20, and the lens is detected by the optical center detector 30 to obtain second optical center information of the lens and transmit the second optical center information to the controller 40; fourthly, the controller 40 can control the three-axis adjusting assembly 20 to drive the absorbing member 243 to move relative to the bearing seat 131 according to the comparison result of the first optical center information of the calibration member and the second optical center information of the lens, so as to complete the primary aligning operation of the lens relative to the lens barrel 200; in the fifth step, the controller 40 can also control the three-axis adjusting assembly 20 to drive the suction member 243 to move relative to the bearing seat 131 according to the comparison result between the outer diameter information of the calibration member and the outer diameter information of the lens barrel 200, so as to complete the secondary aligning operation of the lens relative to the lens barrel 200. When the lens module comprises a plurality of lenses, the operations from the second step to the fifth step are repeated continuously, and the whole lens module can be assembled.

Therefore, when the lens subjected to the primary aligning operation and the secondary aligning operation is assembled in the lens barrel 200, the error between the optical center of the calibration piece and the optical center of the lens and the error between the outer diameter of the calibration piece and the outer diameter of the lens barrel 200 are eliminated, and the tolerance value of the set same optical axis can be met, so that the problems that the maintenance cost is too high due to the deviation and the reassembly is needed, the lens is possibly scratched or even scrapped and the like are avoided.

For example, the controller 40 may include a signal receiving unit, a data operation unit, a signal transmitting unit, a data storage unit, and the like, to receive the first optical center information of the calibration piece, the second optical center information of the lens, the outer diameter information of the calibration piece, and the outer diameter information of the lens barrel 200 through the signal receiving unit, compare the first optical center information of the calibration piece with the second optical center information of the lens, the outer diameter information of the calibration piece, and the outer diameter information of the lens barrel 200 through the data operation unit, respectively, transmit an action command (including detection, movement, and the like) obtained according to the comparison result to the plane adjustment assembly 10, the three-axis adjustment assembly 20, and the optical center detector 30 through the signal transmitting unit, and transmit the first optical center information of the calibration piece, the second optical center information of the lens, the outer diameter information of the calibration piece, and the like through the data storage unit, The comparison result of the outer diameter information of the lens barrel 200, the first optical center information and the second optical center information of the lens, the comparison result of the outer diameter information of the calibration piece and the outer diameter information of the lens barrel 200, the action command obtained according to the comparison result, and the like are subjected to data storage, so that data support is provided for the aligning operation of the lens aligning device 100.

It is noted that the specific structure, testing principles and methods of use of optical center detector 30 will be known to those skilled in the art from the prior art and will not be explained herein.

Optionally, as shown in fig. 2, the bearing seat 131 is a V-shaped structure, the plane adjustment assembly 10 includes a pushing block 141 disposed corresponding to the bearing seat 131, and the pushing block 141 is driven to move toward a side close to the bearing seat 131, so that the pushing block 141 and the bearing seat 131 cooperate to clamp the fixing target and the lens barrel 200, respectively. Certainly, the pushing block 141 is driven to move toward a side far away from the bearing seat 131, so that when the calibration piece and the lens barrel 200 are required to be respectively placed in the bearing seat 131, a sufficient accommodating space can be reserved for placing, that is, the calibration piece and the lens barrel 200 are respectively placed in the bearing seat 131 first, and then the pushing block 141 moves toward a side close to the bearing seat 131, so that the pushing block 141 and the bearing seat 131 are jointly matched to respectively clamp and fix the calibration piece and the lens barrel 200, and meanwhile, when the calibration piece and the lens barrel 200 are required to be respectively taken out of the bearing seat 131, the pushing block 141 and the bearing seat 131 can release the clamping and fixing effects on the calibration piece and the lens barrel 200.

For example, as shown in fig. 2, when the pushing block 141 and the bearing seat 131 cooperate to clamp and fix the calibration piece and the lens barrel 200, respectively, the pushing block 141 and the detecting piece 111 abut against each other, so that the detecting piece 111 obtains the outer diameter information of the calibration piece and the outer diameter information of the lens barrel 200, respectively. Because there is an outer diameter difference between the calibration piece and the lens barrel 200 and between the lens barrels 200 of different specifications, the detecting end of the detecting piece 111 should have scalability, so that when the pushing block 141 and the bearing seat 131 are cooperatively used to clamp and fix the calibration piece and the lens barrel 200, the pushing block 141 and the detecting end of the detecting piece 111 can both be contacted, so as to avoid the phenomenon that the detected object with a smaller outer diameter cannot be contacted with the pushing block 141 to obtain the outer diameter information thereof, and the pushing block 141 and the detecting end of the detecting piece 111 cannot be interfered, so as to avoid the phenomenon that the detected object with a larger outer diameter is damaged by being interfered with the pushing block 141.
