[Prior Art] Image sensing components are mainly divided into two types: Complementary Metal Oxide Semiconductor (CMOS) and Charged Coupled Device (CCD), which have been widely used in various images. For electronic products, such as digital cameras, digital cameras, computer cameras (pcCamera), digital cameras for digital presentations (D〇cumentCam (10), also known as physical projectors), even the car's inverting device can see the image. The use of sensing elements. Let's take a digital camera as an example. Please refer to (a)'/, #, for the video recorder 1 R R R / Μ In the picture we can clearly see 4, 4 (10) 卜 t structure L, from the new moon It can be seen that the digital report captures the image capture device 2, 1 annihilation 1 main package image capture action. For example, the figure-display object 3 performs an exploded view of the device 2, from:::= The image pick-up device 2 includes and clears the image, and the image is 1271997. The capturing device 2 can perform the image capturing operation on the object 3 to be displayed. The working principle of the image sensing element 11 is as shown in the first figure (c). From the block diagram, we can clearly see that the image surface element u functions like a negative film in a conventional camera, and first receives the object by the lens 1G. The light that is projected or reflected, and the image sensing element u utilizes the effect of photoelectric conversion to generate a corresponding number of electricity according to the intensity of the light of the lake, so that the image money can be formed, so that the image Signal 12 (Digital Signal Processor) t performs image processing, and then is output and played by the display device 13 (for example, a liquid crystal screen on a digital camera, a computer screen, etc.), and the user can see through the touch device 13 The most instant image picture, it can be seen that the shadow reduction component u can be said to be an important component affecting the image quality, so the process of assembling and assembling the tilted m image sensing element η and the lens is usually After a relatively precise adjustment, the assembly tolerance between the image sensing element u and the lens 10 is less than a standard value to ensure image quality. [See Figure (d) (e), which is a schematic diagram of the assembly of the lens 1〇1 and the image sensing element 102. It can be clearly seen from the figure that the shirt-like sensing element 102 is bonded to a circuit board. On the 1〇3, the lens (8) is screwed onto one of the screw mounts 〇4, and the base 1042 is directly connected to the circuit board 1〇3. The fixing is generally such that the (four) wire is locked under the circuit board 1G3, so that the lens fixing base is engaged with the circuit board 1〇3, and the length of the screw can be locked. And adjusting the angle of the lens holder 1271997 to the circuit board i〇3, or after the angle between the lens holder 1〇4 and the circuit board 103 is adjusted, and then fixing by using a dispensing method, and then the lens is desired The optical axis 1011 of 101 can be perpendicular to the plane 1〇21 of the image sensing element 102 to achieve better image quality when image capturing is performed, but usually the image sensing element 1〇2 will be with the circuit board 103. There may be some degree of tilt when assembling and joining (for example, the first figure) d)), so that the lens fixing member 104 and the image sensing element 102 may form a certain degree of inclination when assembled and bonded to the circuit board 103, so that the lens assembly The optical axis 1011 of the lens 101 cannot be perpendicular to the plane 1〇21 of the image sensing element 102. If the degree of tilting is too large, the quality of the captured image is seriously affected, so the base of the lens holder 104 must be 1〇42 and the junction of the circuit board 1〇3 are quite time-consuming adjustments (such as re-adjusting the length of the control screw lock described above, or re-adjusting and dispensing) to make the lens 1〇 7 The inclination of the image sensing element 102 with respect to each other can be within a reasonable range (assembly tolerance) without affecting the quality of the image, but is adjusted between the lens 101 and the image sensing element 102 by conventional techniques. The T process, which requires considerable time-consuming and tuned equipment, is also quite expensive due to the need for precise calibration, resulting in considerable cost and time over the entire process. How to improve the lack of conventional technical means is to develop the main purpose of the case.

Therefore, in the present embodiment, The bonding unit 23 is engaged with the board 22; we use the gravity of the circuit board 22 itself to gently press on the fixing unit 23 and fix it by soldering (the fixing unit 24 as shown in the figure) The junction with the circuit board 21 is 25), so that the pressing of the fixing unit 24 and the second plane 222 13 1271997 of the image sensing element 22 is prevented from being too much pressure to cause damage to the image sensing element 22. . Referring to FIG. 2( d ), which is a top view of the first correction mode of the image sensing element 22 of the fixing unit 24 in the preferred embodiment, the figure is further matched with the second figure (b). , we can clearly see that the fixed unit 24 has two contact faces 340 parallel to the optical axis 231 of the lens 23, and we have a first contact surface 2〇1 and a second contact surface perpendicular to each other. 202, and the fixing unit 24 has at least two contact points 24〇 which are not on the same straight line and form a plane perpendicular to the optical axis 231 of the lens 23, and we have a first contact point 301, a The first contact point 302, a third contact point 3〇3 and a fourth contact point 304 are used to indicate the image with the first contact surface 2〇1 and the second contact surface 202 as shown in the figure. One of the first side 2201 of the component and the second side 2202 are closely adhered to form an "L", the shape of the word (the solid line and the dotted line are superimposed as shown in the figure), so that the optical axis 231 of the lens 23 can be The center point of the second plane 222 of the image sensing element 22 is utilized The contact point 3〇1, the second contact point go], the third contact point 303, and the fourth contact point 3〇4 are in contact with the second plane 222 of the image sensing element, in the image sensing Element 22 = forming a -, port, and word shape on the second plane 222 (as shown in the figure: 丄, such that the correction 231 of the lens 23 can be perpendicular to the second plane 222 of the image sensing = 22. - Come on, so that the solid = early 24 can carry the highest degree of precision and fineness of the shadows of the shadow zone when the component 22 is engaged with the circuit board 21 ,, In order to achieve the main purpose of pursuing good image quality. In addition, in the above-mentioned Langshi, we fit the side of the image sensing element 22 with two non-parallel contact faces, mainly to ensure the optical axis of the recording head 23. 231 can more accurately align the image sensing element 22 to the point 2221 'because the light receiving surface of the image sensing element 22 is a two-plane structure' in order to enable the optical axis 231 of the lens 23 to be aligned with the 2 image sensing The center point 2221 of the component 22 must have two In the above-mentioned correction method, we will use the first contact surface 01 and the second contact surface 202 as an example. - The second figure (e) is again requested. In the preferred embodiment, the second correction mode of the image sensing element 22 is as shown in the top view. It can be clearly seen that the material unit 24 can be three different in addition to the contact points of the ligaments. The contact point (30 mb to the second plane 222 of the video element 22 is 妾=妾== as shown in the figure, n, 'word shape (as shown in the figure, the slash to ^f can reach The same effect of the first correction method is the main purpose of the good image quality, and some of the technical means are the same as the above-mentioned slaves, and therefore will not be described here. The technical means described in this section, we can clearly see that the biggest difference between the device and the prior art is that === the device has at least two with the fixed unit and the other side. Using the fixing unit, the contact points of the 15 1271997 plane which are not in the same line and forming a plane perpendicular to the optical axis of the lens are in contact with the second plane of the image sensing element, so that the light of the lens (10) is a center point of the second plane of the image sensing element and perpendicular to the second plane of the image sensing element, so that the optical signal received by the two lenses can be focused onto the second plane of the image sensing element, and the The fixing unit can also be adjusted according to the degree of inclination generated when the image sensing element is engaged with the circuit board, so that the image capturing device can quickly achieve the purpose of accurate correction during the assembly process. Further, the image capturing device can capture a better image quality when the image capturing operation is performed, and the image captured by the saving device is surely changed. Poor quality and lack of accurate calibration of the required time-consuming and costly, and thus achieve the main purpose of the present case. The invention of the present invention is modified by those skilled in the art and is not intended to be protected by the scope of the patent application.
