Description of the Invention: [Technical Field] The present invention relates to a detecting device, and more particularly to an automatic detecting device and a detecting method for a focus lens. [Prior Art] With the continuous development of digital technology, electronic technology is widely used in the field of cameras, digital imaging technology has been rapidly developed, and cameras have become more intelligent. In particular, in recent years, portable electronic devices such as mobile phones and personal digital assistants (pDAs) equipped with digital camera functions have also rapidly developed into high-performance, multi-functional directions to improve the performance of cameras, and while improving resolution, they must be improved. The precision of the camera's autofocus system. A general camera focus system includes an actuator such as a piezoelectric motor, a stepping motor, a voice coil motor, etc., which is mounted in the actuator and driven by the actuator to telescopically move the focus lens. The maximum displacement is about 300~400 microns, so that the focus distance of the image is from infinity to about 10 cm. Since the camera has many different postures during use, such as the most common horizontal placement and vertical placement, The camera is required to achieve a certain degree of precision in different postures, so it is necessary to detect the precision of the displacement of the camera actuator driving lens during different postures to ensure that it has high precision under different use conditions. . SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a multi-directional detection automatic 3 201028788 ‘ detection device and detection method for the displacement of a gastric focus lens. • A displacement detecting device for autofocus lens for detecting, moving, ... the displacement of the lens under the actuator drive, including the bracket sill, the sensor and the driver, the mount and the f The device is disposed on the bracket, and the fixing seat is configured to actuate the bracket to rotate and change the attitude of the actuation n to measure the displacement amount of the lens focus in different safety states. Electrically coupled to the actuator to drive a lens within the actuator to move the focus, the sensor sensing the amount of displacement of the lens of the actuator during focusing. A displacement detecting method for an autofocus lens for detecting a displacement amount of a lens under the driving of an actuator during autofocusing, I including the following steps: providing one frame; and - an actuator with a lens The detectors are respectively fixed at different positions of the bracket; the bracket is rotated to make the lens of the actuator face up, down, and laterally, and the lens is in focus when the lens is facing upward, downward, and laterally, respectively. The amount of displacement in the process, wherein the sequence is: arbitrarily exchanged, in any one of the two processes, the actuator drives the lens to move the focus, the sensor senses the displacement of the lens during the moving focus, and the The amount of displacement sensed in each posture determines whether the actuator is qualified. Compared with the prior art, the detecting device and the detecting method use the rotatable bracket to drive the actuator to rotate and change the attitude of the actuator lens. By simply rotating the bracket to realize the lens in different postures in the 4 201028788 'secondary drive The detection of the amount of displacement during the lower focus process is simple, and the low-cost and fully automated detection can be achieved. [Embodiment] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings. As shown in FIG. 1, the detecting device comprises a base 1 , a frame 20 , a fixing base 30 , a sensor 40 , a controller 5 , a motor 6 , and a driver 70 . The detecting device judges the actuator by checking whether the displacement amount in the process of driving the focus by the actuator 1 在 in the different postures of the lens in the actuator 100 (refer to FIGS. 5 to 7) meets the requirements. 1〇〇 Is it a qualified product? In view of the fact that products such as cameras are most commonly used for lateral placement and longitudinal placement during use, the detection device detects the lens in lateral and longitudinal postures, that is, in the three postures including lens up, lens down, and lens lateral direction, the actuator The amount of displacement of the 100-lens lens telescopic movement is determined to determine whether the actuator 100 is qualified. If any one of the detection results is not satisfied, it means that the actuator 100 is a non-conforming product, and the detection should be terminated, and the product is rejected. Otherwise, if all the above detection results meet the requirements, the actuator 1 is indicated. 〇〇 is a qualified product 'end inspection. The detecting device and detecting method of the present invention will be described in detail below. The base 10 has a flat shape and is formed with a horizontal upper surface 12. The bracket 20 is mounted on the upper surface 12 of the base 10. The fixing base 30 and the sensor 40 are disposed on the bracket 20, and the fixing base 5 201028788 30 is used for placing the actuator 100 to be detected. The driver 70 is electrically Connected to the motor 60 and the actuator 100, the controller 50 is electrically connected to the sensor 40. In order to simplify the illustration, the electrical connection relationship between the above components is not shown in the drawings, and it can be understood that the electrical connection relationship between the respective components can be realized by a simple wire connection. For each detection attitude, the motor 70 is first driven by the driver 70 to rotate and then the bracket 20 is rotated to a specific to-be-detected attitude by the pivot 8〇, and then the driver 70 drives the lens to move telescopically through the actuator 1〇〇. Focusing, at this time, the sensor 4 〇 senses the displacement of the lens during the focusing process, and the controller 5 电 is electrically connected to the sensor 4 并 and outputs a signal according to the measurement result of the sensor 40 , according to the signal $ can judge whether the 丨 actuation g (10) is qualified in the special money, and after the field is qualified in a special posture, the drive 7 is driven by the driver 7 旋转 to rotate and drive the bracket 2 to rotate to change the posture of the actuator 〇〇 'Continue testing. The bracket 2 includes a vertical support portion 22 and an operating portion 24 coupled to the support portion 22. The supporting portion 22 and the operating portion 24 are both in a plate shape, wherein the supporting portion 22 is perpendicular to the base 10 and is defined on the upper surface 12 of the base 10, and the operating portion 24 is coupled to the supporting portion 22 via a pivot 80. The pivoting portion 8 is fixedly connected to the operating portion 24, such as an interference fit, and is snap-fitted so that the operating portion 24 can rotate in synchronization with the pivot 8'. In this embodiment, the up to 60S is placed in the rear of the operation unit 24 to serve the motor, thereby realizing the actuator 100 to measure the posture using the high-precision attitude, speed, torque, and communication control of the feeding motor. The precise determination of the position of the pivot axis 80 is the output shaft of the motor 60. It can be understood that: When the position of the installation is limited, the motor 60 can be disposed at a position away from the operating portion 24. At this time, the pivot 80 can be a component separate from the motor 60 through other components such as gears. It is connected to the output shaft of the motor 60 or directly to the output shaft of the motor 6〇, thereby enabling long-distance transmission. The fixing base 30 and the sensor 40 are respectively disposed at both ends of the operation portion 24. The sensor 40 can be a non-contact laser displacement sensor or a contact capacitive sensor. As shown in FIG. 2 to FIG. 4, the fixing base 30 includes a bottom plate 32 and a cover plate 34'. The two ends of the bottom plate 32 (the rear side in FIG. 2 and FIG. 3 are the right side in FIG. 4) respectively A bump 320 is disposed upwardly. A connecting rod 322 is disposed between the two bumps 32. The bottom plate 32 is opposite to the side on which the bump 320 is disposed (the front side in FIG. 2 and FIG. 3, φ in FIG. 4 The outer side surface 321 of the left side protrudes outwardly to form a lug 324. The center of the bottom plate 32 is convexly disposed with a plurality of positioning posts 326. The positioning posts 326 are disposed separately, and a columnar capacity is formed between the positioning posts 326. a space 90 is provided for the actuator 100. The accommodating space 90 is provided with a plurality of pins 328. The top end of the plug 328 is slightly protruded from the bottom plate 32, and is lower than the top end of the positioning post 326. The bottom end passes through the bottom plate 32, and the pin 328 is made of a conductive material. The cover plate 34 includes a body 340 and 7 opposite the bottom plate 32. 201028788 • A fastening portion 342. The body 340 corresponds to the connection of the bottom plate 32. One side of the rod 322 is formed with a perforation (not labeled), and the perforation is provided for the connecting rod 322 of the bottom plate 32 to be connected to the bottom plate > The cover plate 34 is rotatable about the connecting rod 322 of the bottom plate 32 to open the cover plate 34 (Figs. 2, 3) to place the actuator 100 or to close after the actuator 100 is placed (Fig. 4). A central portion of the body 340 corresponding to the receiving space 9 底板 of the bottom plate 32 defines a through hole 346 ′. Therefore, during the detecting process, the detection signal sent by the sensor 40 can directly reach the solid seat through the through hole 346 . The actuator 1 in 30 increases the accuracy of the detection. The fastening portion 342 extends vertically downward from a side of the cover plate 34 opposite to the through hole, and an inner side surface thereof defines a recess 344 which cooperates with the lug 324 of the bottom plate 32. As shown in FIG. When the actuator 100 is placed in the accommodating space 90, the positioning post 326 is disposed on the outer side surface of the actuator , 1 , and the top end of the latch 328 is pressed against the lower side of the actuator 100 . The circuit is electrically connected to the circuit in the actuator 1B, and the bottom end of the pin 328 is connected to the driver 7A to connect the actuator 1 to the driver 70. As shown in FIG. 4, after the actuator 100 is placed, the cover plate 34 is rotated to the closed state, and the lug 324 of the bottom plate 32 is received in the recessed hole 344 of the engaging portion 342 of the cover plate 34, and the cover is closed. The bottom surface of the plate 34 is formed to abut against the top surface of the actuator 1 , so that the actuator 100 is fixed in the fixing base 3 to prevent the fixing base 30 from rotating at the operating portion 24 of the bracket 2 . The actuator 100 moves during the 201028788 process. As shown in FIG. 8 , after the actuator 1 is placed in the fixed seat 3 , the actuator 1 开始 is detected. First, referring to FIG. 5 , the lens of the actuator 100 is detected to face upward. After the start switch is pressed, the drive 70, that is, the drive motor 60 is rotated, and the operating portion 24 of the bracket 20 is rotated by the pivot 80, and the operation portion 24 is rotated to the vertical direction, that is, the sensor 4 and the actuator On a vertical line, the sensor 40 is on and the actuator is on, and the driver 70 controls the motor 6 to stop rotating, so that the lens in the actuator 1 is maintained in an upward posture. The driver 7 can be a processor or an external processor, and the execution program is pre-recorded inside the processor to enable fast detection. When the lens of the actuator 100 is maintained in the upward posture, the sensor 40 emits a measurement signal from the top to the bottom, and at this time, the actuator 7 drives the lens in the actuator 1 to telescopically move the focus to measure the actuation. The displacement amount of the device 100 in the lens upward posture is as shown in FIG. 9. In this process, the lens is first driven to focus to a distant position and the displacement amount of the lens is measured by the sensor 40, and then the lens is driven to move to focus. At the position of the lens at this time, the difference between the two displacement amounts is calculated by the sensor 40, which is the displacement amount of the actuator 1 in the posture of the mirror upward. Obviously, it is also possible to measure the amount of displacement of the lens to the near position, and then detect the displacement of the lens to a distant position I 隶 §·}} to calculate the difference between the two to get the displacement. The controller 5 产生 generates a corresponding output signal 201028788 according to the measurement result of the sensor 40, and according to the §fl number, it can be judged whether the actuator J 合格 is qualified. If the measured displacement amount does not meet the requirements, it indicates that the actuator 100 is unqualified, and if the measured displacement amount meets the requirement, it indicates that the actuator 100 meets the requirements in this posture, and can continue to perform other states. Check / then. In order to ensure the accuracy of the detection, the actuator 1 can repeatedly perform multiple times of displacement detection in any attitude. The number of detections is not more than 100 times. If it does not meet the requirements, it will not indicate the product. qualified. ❹ When the actuator 100 is qualified in the lens up posture, 'the operating portion 24 of the bracket 20 is again driven to rotate to the horizontal posture' to detect the displacement amount when the lens of the actuator 100 is placed laterally, as shown in FIG. The lens of the actuator 1〇〇 is in a leftward posture, that is, the sensor 40 is on the left and the actuator 1 is on the right, and the sensor 4 is transmitting the measurement signal from left to right, which can actually be actuated. The lens of the device 1 测量 is measured to the right 'that is, the sensor 40 is on the right and the actuator 1 is on the left, 感 the sensor 40 emits a measurement signal from right to left. The method of measuring the displacement amount when the lens of the actuator 100 is upward is the same as the displacement amount when the lens is placed laterally is also driven by the driver 7 〇 to drive the lens telescopic movement in the actuator 1 分别 to focus to the far and near, respectively. And calculating the difference between the lens displacement amount when focusing to the far place and the near position, the displacement amount of the lens 100 in the lateral direction of the lens is obtained, and if the displacement amount does not meet the requirement, the same indicates that the actuator 1 is unqualified. In the end, it indicates that the actuator 100 meets the requirements in this posture, and the detection can be continued. 201028788 As shown in Fig. 7, 'final detection of the actuator 1〇〇 in the downward direction of the lens is performed, and at this time, the operation portion 24 of the driving bracket 2〇 is rotated again to the vertical posture to make the actuator j〇 With the lens of the cymbal facing down, even if the sensor 40 is under the actuator and the actuator is oscillating, the sensor 4 发射 emits the measurement signal from the bottom to the top, and the lens 70 is also driven by the driver 70 to move the lens to move to the far focus. At the vicinity and near, the difference between the lens displacement when the focus is far and near is the displacement of the actuator 100 in the downward direction of the lens. If the value of the displacement does not meet the requirements, it means The actuator 100 fails; otherwise, the actuator 100 meets the requirements in this posture, that is, the actuator 100 meets the requirements in various detection postures, and the test is 'qualified'. In the above detection process, the automatic detection of the actuator 100 in different postures can be easily realized by rotating the bracket 20, which is simple and quick. It can be understood that the above three detection postures, that is, the lens facing ❿ ^, the lens facing downward, and the lens lateral direction, the order can be arbitrarily adjusted to save the program as a principle. In addition, the judgment of whether the displacement amount meets the requirements can be performed by the processor, and the standard value of the displacement amount of the actuator (10) is prestored in the processor, and the controller 50 is electrically connected to the processor to connect the sensor. 4〇The measured data is converted into digital: the number processor compares the measured data with the standard Fengbei (four) broken product whether it meets the requirements and according to the judgment, the corresponding output signal, more Huaiyin, the disk is further The output terminal β of the processor is connected to an indicator such as the indicator light 200 (Fig. 1), etc., when the processing 11 201028788 device f outputs a signal that does not meet the requirements, the indicator light is on, and the warning detection = the actuator 100 is not In accordance with the requirements, it is convenient to eliminate the unqualified products, so as to effectively ensure that the products manufactured after testing have high performance in any use posture.
