Description of the Invention: [Technical Leadership of the Invention] [0001] The present invention relates to a concentricity detecting device and a detecting method, and more particularly to a lens module concentricity detecting device and a detecting method thereof. [Prior Art] [0002] In recent years, with the development of optical products, the application range of lens modules has continued to expand, such as digital cameras and electronic products with camera functions. For electronic products, especially consumer electronic products, the development trend is lighter and thinner. The corresponding lens modules are also getting smaller and smaller, and the precision requirements are getting higher and higher. The assembly process of the module also requires higher precision and stability to ensure production efficiency and yield. [0003] Generally, the assembly process of the lens module includes assembling an optical component such as an optical lens, a spacer, and a diaphragm into a lens barrel, and then assembling the lens barrel with the optical component into the lens holder, the lens barrel and the lens holder. The structure is generally connected by an intermeshing structure such as a threaded structure or the like. After the lens barrel is loaded into the lens holder, a step of detecting the concentricity between the lens barrel and the lens holder is further included. Generally, a light source is disposed on the side of the lens barrel at the axial direction of the lens barrel. a position sensing element is disposed near the focus position of the optical lens in the other side of the lens barrel, and the light source is used to illuminate the lens barrel, and the light enters the lens barrel and then forms a spot on the position sensing element. Manually rotating the lens barrel so that the lens barrel (4) is at the angle of the lens holder (four), repeating the above steps, and subtracting another spot on the sensing element at the position; comparing whether the distances between the centers of the two spots are mutually allowed Within the range of error. 09611029^^^^* A〇101 Page 3 of 21^13279281-0 1375789 ___ 101 years. July 23rd shuttle replacement page [0004] However, the practice of manually rotating the lens barrel is slow and efficient. And the accuracy is low, and due to the influence of human fatigue and mood, it is impossible to ensure that the required angle can be achieved every time the manual rotation is performed, and sometimes a large error occurs. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a high-efficiency and high-precision concentricity detecting device and a concentricity detecting method. [0006] A concentricity detecting device for detecting an axial concentricity between a lens barrel and a lens holder in a lens module. The concentricity detecting device includes a light source, a detecting jig and an optical axis shift detecting device. The optical axis offset detecting device is disposed opposite to the light source for recording the optical axis projection position of the lens barrel and sensing the optical axis projection offset. The test fixture includes an outer sleeve and an inner sleeve disposed in the outer sleeve, the inner sleeve being rotatable relative to the outer sleeve by a predetermined angle, the inner sleeve being used for the barrel co-operate. [0007] A concentricity detecting method 'for detecting a car center concentricity between a lens holder and a lens barrel disposed in the lens holder, the concentricity detecting method comprising the following steps: providing a detecting jig, the detecting The fixture includes an outer sleeve and an inner sleeve disposed in the outer sleeve, the inner sleeve being rotatable relative to the outer sleeve by a predetermined angle to engage the inner sleeve with the lens barrel; Illuminating the lens barrel to form a first spot, the optical axis offset detecting device records the position of the first spot; fixing the lens holder, rotating the inner sleeve relative to the outer sleeve by a predetermined angle, thereby the lens barrel Rotating a predetermined angle with respect to the lens holder; illuminating the lens barrel with the light source to form a position of the second light spot' fine deviation detecting device for recording the second spot, and the sound number is AG101 ^ 4 1 / ^ 21 I 1013279281 -0 09611029? 1375789 On the 23rd of the 101st, the relative offset between the second position and the first position is judged to be within the error tolerance. [0008] Compared with the prior art, the concentricity detecting device of the present invention comprises a detecting fixture, and the inner sleeve can be rotated by a predetermined angle with respect to the outer sleeve. The use of the detecting fixture can save manpower, reduce production cost, and reduce efficiency. Further, the concentricity detecting device can be used to control the rotation of the lens barrel more accurately. [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. Referring to FIG. 1 to FIG. 3 together, FIG. 1 is a schematic diagram of a concentricity detecting device 100 and a lens module 200 to be detected according to a first embodiment of the present invention. [0011] The lens module 200 to be detected includes a lens holder 22, a lens barrel 24 disposed in the lens holder 22 and meshingly coupled to the lens holder 22, and at least one lens 26 disposed in the lens barrel. The concentricity detecting device 100 is configured to detect the axial concentricity between the lens barrel 24 and the lens holder 22 after the lens barrel 24 is assembled into the lens holder 22, that is, the axial center of the lens barrel 24 and the lens holder 22 Positional deviation between the axes. The outer edge of one end portion of the lens barrel 24 is provided with a plurality of notches 242, and the plurality of notches 242 of the embodiment are uniformly disposed at the outer edge of the end portion of the lens barrel 24. [0012] The concentricity detecting device 100 includes a light source 12, a detecting fixture 14, a detecting platform 16, and an optical axis offset detecting device 18° in the optical axis direction. [0013] As shown in FIG. 4, the detection is performed. The jig 14 includes an outer sleeve 142 and an inner sleeve 144 in which the outer sleeve 142 is disposed. The outer sleeve 142 and the inner sleeve 144 can be relatively rotated by a predetermined angle 0 (where 〇° < 0 < 0 〇 °), in the present _ a single number fine 1 page 5 / total 21 pages 1013279281-0 [0014] [0017] [0017] [0017] The July, 2011 day is replaced by positive = in the embodiment 0 = 18 〇. . A spring (not shown) is coupled between the outer sleeve 14 2 and the inner sleeve 14 4, and the spring returns the outer sleeve 42 and the inner sleeve 144 to an initial position by elastic force (described later). The inner wall of the inner sleeve 144 is provided with a plurality of projections 1444 for cooperating with the notches 242 of the lens barrel 24 to drive the lens barrel 24 to rotate together. A protrusion 1442 is disposed on the outer wall of the inner sleeve 144. The outer sleeve 142 is provided with a horizontal groove 1424 and a vertical groove 1422. The horizontal groove 1424 and the vertical groove 1 422 serve as guide rails, and the protrusion 1442 moves along the guide rail to realize the outer sleeve 142 and the inner sleeve. The phase | of the sleeve 144 is rotated. The length of the horizontal groove 1424 is determined by a predetermined angle 0 that requires rotation, in the present embodiment <9=180. Therefore, the horizontal groove 1424 has a length of half a circumference. When it is desired to rotate the inner sleeve 144 relative to the outer sleeve 142, the inner sleeve 144 is depressed along the vertical groove 1422 of the outer sleeve 142 and then rotated counterclockwise along the horizontal groove 1424 to the horizontal groove. At the end of 1424, inner sleeve 144 is rotated relative to outer sleeve 142 by a predetermined angle of 0 = 18 。. . When it is necessary to return the inner sleeve 144 and the outer sleeve 142 to the initial state, the inner sleeve read 144 is rotated clockwise along the horizontal groove 1424 to the end of the horizontal groove 1424, and then the elastic force of the upward pulling by the spring is restored to When it reaches the initial state. Referring to FIG. 1 to FIG. 3 again, the detecting platform 16 is provided with a placing slot 162 and a through hole 164. The slot 62 is used for placing the lens module 200 to be detected, and the through hole 164 is used for the light source 12 to be emitted. The light rays can pass through the detection platform 16 to the optical axis offset detecting device 18. The lens holder 22 of the present embodiment has a circular cross section, and thus is used for placing the lens mold 09611029# single number A including the lens holder 22. 101 Page 6 of 21 1013279281-0 1375789 The placement slot 122 of the group 200 is also designed to be circular. Of course, the placement slot i22 can be changed according to the shape of the lens holder 22, and is not limited to the embodiment of the through hole 164. The cross section is also circular 'and is disposed coaxially with the placement slot 162. [0018] The optical axis offset detecting device 18 is configured to record the projection position of the optical axis of the lens barrel when the light source 18 is twice illuminated by the lens barrel 12, and sense whether the distance of the relative offset of the optical axis projection position is within the error tolerance range. Preferably, the optical axis shift detecting device 20 is disposed near the optical axis focus of the lens barrel 12. In the present embodiment, the optical axis of the lens module 200 and the axis of the lens barrel 22 are approximately coincident, so that the spot records the axial center position of the lens barrel 12. The optical axis offset detecting device 18 can be a light sensitive component such as a Charge Coupled Device (CCD) or the like. [0019] The optical axis concentricity detection process of the lens module 200 by the concentricity detecting device 100 is as follows: [0020] (1) The lens module 200 to be detected is placed in the placement slot 162, and the detection platform is 16 thereby fixing the lens holder 22 and fitting the detecting fixture 14 to the lens module 20 0; [2] turning on the light source 12 to illuminate the lens barrel 24 to form a first spot (not shown), and the optical axis is biased The displacement detecting device 18 records the position of the first spot; [0022] (3) pressing the inner sleeve 144 along the vertical groove 1422 of the outer sleeve 142, and then rotating counterclockwise along the horizontal groove 1424 to the horizontal At the end of the recess 1424, the inner sleeve 144 is rotated relative to the outer sleeve (4) by a predetermined angle Θ. This embodiment takes 0-180 as an example. Since the fixed inner sleeve 144 of the lens holder 22 cooperates with the lens barrel 24 and drives the rotation of the lens barrel, the mirror is rotated by 180° with respect to the lens holder 22; 21 pages 09_production order number 1 1013279281-0 1375789 [ [0027] [0027] [0027] [0027] On July 23, 101, according to the replacement page (4) the light source 12 illuminates the lens barrel 24 to form a second spot (not shown), the optical axis offset detecting device 18 recording the position of the second spot, and comparing the offset of the center of the second spot with respect to the first spot, determining whether the offset is within the tolerance of the error, if the lens barrel 24 and the mirror The axial concentricity between the seats 22 meets the requirements; if not, the optical axis concentricity between the lens barrel 24 and the lens holder 22 does not meet the requirements. When the above detection process is completed, 'the inner sleeve 144 is rotated clockwise along the horizontal groove 丨 424 to the end of the horizontal groove 1424' when the protrusion 1442 reaches the boundary between the horizontal groove 1424 and the vertical groove 1422. The barrel 144 is restored to the initial state by the upward force of the spring _ spring, and the steps (1)-(4) can be repeated to detect the next lens module. In the present embodiment, the lens barrel 24 is rotated by 180 with respect to the lens holder 22, and the axial concentricity between the lens barrel 24 and the mirror holder 22 is detected by the offset of the two spots obtained before and after the comparison. In practice, 'can rotate other angles, such as 90. , 270. Wait. Of course, it is also possible to rotate a plurality of data for multiple times, thereby obtaining higher detection accuracy. Compared with the prior art, the concentricity detecting device 1 of the present embodiment includes an I detecting fixture 14 , and the inner sleeve 144 can be rotated by a predetermined angle with respect to the outer sleeve 142 , and the detecting fixture 14 can be used.

The horizontal recess 402 acts as a guide rail that slides along the horizontal recess 4022 as the inner sleeve 404 rotates relative to the outer sleeve 402. [0029] Please refer to FIG. 7' for the detection fixture 5 of the fourth embodiment of the present invention. The detecting jig 50 is similar to the detecting jig 14 of the first embodiment, except that the outer sleeve 502 has no recessed structure, and the inner sleeve 5〇4 and the outer sleeve 5〇2 are threadedly engaged. When the inner sleeve 504 is rotated clockwise relative to the outer sleeve 502, the inner sleeve 504 is rotated relative to the outer sleeve 502 by a predetermined angle 0 (where '<0>0<0>36.). Preferably, 0 = 18 〇. . [0030] The detection process of the axial concentricity between the lens barrel 24 and the lens holder 22 by using the detecting fixtures 3, 40, and 50 is similar to the detection process using the detecting fixture 14, and will not be described herein.
