Description

Technical Field

[0001] The present application relates to the technical field of position adjustment devices, and more specifically, to an adjustment device and a camera assembly. Background Art

[0002] In the industrial production process, it is necessary to promptly discover product defects and quickly solve corresponding production problems to improve product yield. Using a line scan camera to inspect products is an efficient means of inspection. During the inspection process, the line scan camera is usually fixed on a bracket so that the lens of the line scan camera faces the loading platform. However, due to manufacturing errors in the bracket and assembly errors between the line scan camera and the bracket, after the line scan camera is installed on the bracket, it is easy for the actual angle of the line scan camera to differ greatly from the preset angle, thereby affecting the image acquisition effect of the line scan camera. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide an adjustment device and a camera assembly, by which the angle of a line scan camera can be adjusted, so that the difference between the actual angle of the line scan camera and the preset angle is smaller, thereby improving the image acquisition effect of the line scan camera.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] In a first aspect, a regulating device is provided, comprising:

[0006] A first bracket, the first bracket is used to carry the part to be adjusted;

[0007] The second bracket, the first bracket can rotate relative to the second bracket until the first bracket and the second bracket are relatively fixed by a locking structure;

[0008] A first adjustment structure, the first adjustment structure is used to drive the first bracket to rotate around the first axis;

[0009] A second adjustment structure, the second adjustment structure is used to drive the first bracket to rotate around the second axis;

[0010] The first axis extends along a first direction, the second axis extends along a second direction, and the first direction is perpendicular to the second direction.

[0011] The beneficial effect of the adjustment device provided by the present application is that the adjustment device of the present application can be used to adjust the angle of the line scan camera. The line scan camera is installed on the first bracket as a to-be-adjusted member. The first bracket can be rotated relative to the second bracket around the first axis by the first adjustment member, and the first bracket can be rotated relative to the second bracket around the second axis by the second adjustment member. Since the first axis extends along the first direction and the second axis extends along the second direction, and the first direction is perpendicular to the second direction, the two rotational degrees of freedom of the line scan camera can be adjusted by rotating the line scan camera around the first axis and the second axis, thereby adjusting the angle of the line scan camera to reduce the difference between the actual angle of the line scan camera and the preset angle. After the angle adjustment of the line scan camera is completed, the first bracket and the second bracket are fixed by the locking structure, thereby fixing the line scan camera at the adjusted angle. Through the above adjustment device, the angle of the line scan camera can be adjusted and fixed, the difference between the actual angle of the line scan camera and the preset angle can be reduced, and the image acquisition effect of the line scan camera can be improved.

[0012] In a second aspect, a camera assembly is provided, comprising a camera and an adjusting device provided by the above technical solution, wherein the camera is mounted on a first bracket of the adjusting device.

[0013] Since the camera assembly includes a camera and the adjustment device provided by the above technical solution, the angle of the camera can be adjusted by the adjustment device to reduce the difference between the actual angle of the camera and the preset angle, thereby improving the image acquisition effect of the camera.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that when an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element. The terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0040] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0041] like Figure 1 and Figure 2As shown, an embodiment of the present application provides an adjustment device 1, including a first bracket 100, a second bracket 200, a locking structure 400, a first adjustment structure 310 and a second adjustment structure 320. The first bracket 100 is used to carry the to-be-adjusted member 3, and the to-be-adjusted member 3 can be placed or mounted and fixed on the first bracket 100, so that the to-be-adjusted member 3 can rotate with the rotation of the first bracket 100. The first bracket 100 can rotate relative to the second bracket 200 until the first bracket 100 and the second bracket 200 are relatively fixed by the locking structure 400. When the locking structure 400 does not completely lock the first bracket 100 and the second bracket 200, the first bracket 100 can rotate relative to the second bracket 200. When the locking structure 400 locks the first bracket 100 and the second bracket 200, the first bracket 100 and the second bracket 200 are relatively fixed, and the first bracket 100 cannot rotate relative to the second bracket 200. Therefore, during the process of adjusting the angle of the first bracket 100, the locking structure 400 is in an unlocked state. After the adjustment is completed, the locking structure 400 locks the first bracket 100 and the second bracket 200 so that the first bracket 100 is fixed to the adjusted angle. The first bracket 100 can rotate around the first axis L1 and the second axis L2 relative to the second bracket 200. The first adjustment structure 310 is used to drive the first bracket 100 to rotate around the first axis L1, and the second adjustment structure 320 is used to drive the first bracket 100 to rotate around the second axis L2. The first axis L1 extends along the first direction, and the second axis L2 extends along the second direction. The first direction is perpendicular to the second direction.

[0042] A spatial rectangular coordinate system is established with the first direction, the second direction and the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. In the drawings of the embodiments of the present application, the first direction is indicated by X, the second direction is indicated by Y, and the third direction is indicated by Z. The first axis L1 extends along the first direction, and the second axis L2 extends along the second direction. By rotating the first bracket 100 along the first axis L1 and rotating the first bracket 100 along the second axis L2, the angle between the first bracket 100 and the plane formed by XY can be adjusted.

[0043] The adjustment device 1 provided in the embodiment of the present application can be used to adjust the angle of the part to be adjusted 3, and fix the part to be adjusted 3 at the adjusted angle after the adjustment. Exemplarily, the adjustment device 1 can be used to adjust the angle of the line scan camera, that is, the line scan camera can be carried on the first bracket 100 as the part to be adjusted 3, and the first bracket 100 drives the line scan camera to rotate around the first axis L1 and the second axis L2 to adjust the angle of the line scan camera.

[0044] In a specific use scenario, the line scan camera is fixed to one side of the stage through the adjustment device 1, so that the line scan camera can capture images of the items on the stage to detect defects of the items. The items can be Micro LEDs (Micro-Light Emitting Diodes), and the line scan camera can be used to detect abnormal display lamp beads in Micro LEDs (for example, lamp beads with dark lights, bright lights, color cast, etc.), as well as abnormal conditions such as cracks, scratches, and missing corners. When the working surface of the stage (that is, the surface of the stage for carrying items) is parallel to the plane formed by XY, the axis of the lens of the line scan camera (hereinafter referred to as the third axis L3) is perpendicular to the working surface of the stage, and the imaging effect of the line scan camera is better, that is, when the line scan camera is at a preset angle, the third axis L3 is perpendicular to the working surface of the stage, or the third axis L3 extends along the third direction. That is, after the line scan camera is fixed to the first bracket 100, the axis of the lens of the line scan camera (hereinafter referred to as the third axis L3) extends along the third direction, so that the line scan camera can obtain better imaging effect.

[0045] After the line scan camera is installed on the first bracket 100, an image is collected by the line scan camera and the image quality is judged. If the edge of the image appears blurred, it means that the third axis L3 does not extend along the third direction. In this case, the first bracket 100 drives the line scan camera to rotate around the first axis L1 through the first adjustment structure 310, and the first bracket 100 drives the line scan camera to rotate around the second axis L2 through the second adjustment structure 320. Through the cooperation of one or both of the first adjustment structure 310 and the second adjustment structure 320, the angle of the line scan camera is changed, so that the third axis L3 extends along the third direction. The image is captured again by the line scan camera and the image quality is determined. If the imaging effect of the entire area of ​​the image captured by the adjusted line scan camera is consistent or substantially consistent (that is, there is no or reduced area with obvious blur), the locking structure 400 is used to fix the first bracket 100 and the second bracket 200, that is, the line scan camera carried by the first bracket 100 is fixed at the current angle. In the subsequent process of using the line scan camera to capture images, the angle of the line scan camera will not change, so that the line scan camera can be used to capture images with better imaging effects, which is conducive to obtaining more accurate detection results, so as to achieve better detection effects.

[0046] The first adjustment structure 310 is used to make the first bracket 100 rotate relative to the second bracket 200 around the first axis L1, and the second adjustment structure 320 is used to make the first bracket 100 rotate relative to the second bracket 200 around the second axis L2. According to the different installation positions of the first adjustment structure 310 and the second adjustment structure 320, there are many specific configuration methods for the first adjustment structure 310 and the second adjustment structure 320.

[0047] For example, in a feasible setting, the first adjustment structure 310 and the second adjustment structure 320 can both be installed on the first bracket 100, and the first adjustment structure 310 and the second adjustment structure 320 can both be against the second bracket 200, the first adjustment structure 310 can move in the second direction relative to the first bracket 100, and the second adjustment structure 320 can move in the first direction relative to the first bracket 100.

[0048] In another feasible setting method, the first adjustment structure 310 and the second adjustment structure 320 can both be installed on the second bracket 200, and the first adjustment structure 310 and the second adjustment structure 320 can both be against the first bracket 100, the first adjustment structure 310 can move in the second direction relative to the second bracket 200, and the second adjustment structure 320 can move in the first direction relative to the second bracket 200.

[0049] In another configuration, the first adjustment structure 310 is mounted on the first bracket 100, the first adjustment structure 310 can move along the second direction relative to the first bracket 100, and one end of the first adjustment structure 310 abuts against the second bracket 200. The second adjustment structure 320 can move along the first direction relative to the second bracket 200, and one end of the first adjustment structure 310 abuts against the first bracket 100. The first adjustment structure 310 and the second adjustment structure 320 are respectively mounted on the first bracket 100 and the second bracket 200, so that the angle of the first bracket 100 can be adjusted when relatively fewer adjustment structures are added to the first bracket 100 and the second bracket 200, that is, it is easier to arrange the layout design of the first adjustment structure 310 and the second adjustment structure 320, and the first adjustment structure 310 and the second adjustment structure 320 can respectively have a relatively larger adjustment operation space.

[0050] It is worth noting that the intersection of the first axis L1 and the second axis L2 is the rotation center of the first bracket 100, and the extension line of the moving track of the first adjustment structure 310 and the extension line of the moving track of the second adjustment structure 320 do not pass through the rotation center. After the first adjustment structure 310 moves along the second direction, the distance between the first bracket 100 and the second bracket 200 where the first adjustment structure 310 is provided changes, so that the first bracket 100 rotates around the first axis L1 relative to the second bracket 200. After the second adjustment structure 320 moves along the first direction, the distance between the first bracket 100 and the second bracket 200 where the second adjustment structure 320 is provided changes, so that the first bracket 100 rotates around the second axis L2 relative to the second bracket 200.

[0051] To facilitate installation of the second adjustment structure 320, Figure 3As shown, in some feasible embodiments, the second bracket 200 includes a first base 210 and an adjustment base 220, the number of the adjustment base 220 is two, the two adjustment bases 220 are installed on the first base 210 at intervals along the first direction, at least part of the structure of the first bracket 100 is located between the two adjustment bases 220, and at least two second adjustment structures 320 are arranged at intervals along the third direction on the two adjustment bases 220. The extension line of the moving trajectory of each second adjustment structure 320 does not pass through the rotation center. Since the second adjustment structure 320 moves along the first direction, and the first axis L1 extends along the first direction and passes through the rotation center, the plurality of second adjustment structures 320 are arranged at intervals from the first axis L1 in the third direction. In a preferred embodiment, at least one second adjustment structure 320 is arranged on both sides of the first axis L1 along the third direction. When the second adjustment structure 320 on one side of the first axis L1 along the third direction moves toward the first bracket 100, the second adjustment structure 320 on the other side of the first axis L1 along the third direction moves away from the first bracket 100.

[0052] The adjustment seat 220 and the first base 210 can be an integral structure, for example, manufactured by an integral molding process such as injection molding, casting, etc., or the adjustment seat 220 and the first base 210 can be manufactured as an integral structure by a large-sized plate through a process such as cutting. The adjustment seat 220 and the first base 210 can be a split structure, and the adjustment seat is fixedly connected to the first base 210 so that the relative position between the adjustment seat 220 and the first base 210 is fixed. Exemplarily, the adjustment seat 220 and the first base 210 can be connected by bonding, welding, clamping, etc., and the adjustment seat 220 and the first base 210 can also be connected by bolts, pins, etc.

[0053] exist Figure 4 and Figure 5 As shown in the angle, the third direction is the up-down direction, the first direction is the left-right direction, and the second direction is the direction perpendicular to the paper. In a specific example, the second bracket 200 includes a first base 210 and two adjustment seats 220, and the two adjustment seats 220 are spaced apart on the first base 210 in the left-right direction, and at least part of the first bracket 100 is located between the two adjustment seats 220. Taking the example of two second adjustment structures 320 installed on the left adjustment seat 220, the two second adjustment structures 320 are spaced apart in the up-down direction, and the two second adjustment structures 320 are respectively located on both sides of the first axis L1, and the right sides of the two second adjustment structures 320 are respectively abutted against the left side of the first bracket 100. Figure 4As shown, the angle between the left side of the first bracket 100 and the right side of the adjustment seat 220 is α1. The second adjustment seat 220 located above moves to the right (i.e., moves toward the first bracket 100), and the second adjustment seat 220 located below moves to the left (i.e., moves away from the first bracket 100). Figure 5 As shown, after each second adjustment seat 220 moves, the angle between the left side of the first bracket 100 and the right side of the adjustment seat 220 is α2, and the first bracket 100 rotates around the second axis L2 by an angle of α3, α3 = α2-α1. Since the adjustable member 3 is installed on the first bracket 100, the adjustable member 3 rotates with the first bracket 100 by an angle of α3.

[0054] In order to improve the position stability of the first bracket 100 after the second adjustment structure 320 completes the angle adjustment and before the locking structure 400 locks the first bracket 100 and the second bracket 200, a plurality of second adjustment structures 320 are respectively arranged on the two adjustment seats 220, and two or more second adjustment structures 320 are respectively arranged on each adjustment seat 220 along the third direction. The number of second adjustment structures 320 arranged on the two adjustment seats 220 may be the same or different, and the second adjustment structures 320 arranged on the two adjustment seats 220 may be arranged one by one or not relative to each other. Since the first bracket 100 is respectively in contact with multiple second adjustment structures 320 on two opposite sides, during the angle adjustment process, each second adjustment structure 320 is moved relative to the adjustment seat 220 to enable the first bracket 100 to rotate around the second axis L2. After the adjustment is completed, each second adjustment structure 320 is relatively fixed to the second bracket 200. The first bracket 100 is limited to a certain extent from both sides of the first bracket 100 by multiple second adjustment structures 320, thereby improving the positioning stability of the first bracket 100 at the current angle, so as to facilitate the subsequent operation of fixing the first bracket 100 to the second bracket 200.

[0055] In the case where multiple second adjustment structures 320 are provided on both adjustment seats 220, at least four adjustment seats 220 are provided on the second bracket 200, that is, two second adjustment structures 320 are provided on the two adjustment seats 220 at intervals along the third direction. Optionally, the second adjustment structures 320 on the two adjustment seats 220 are arranged opposite to each other and coaxially. The two second adjustment structures 320 are arranged opposite to each other, that is, the extension lines of the axes of the two second adjustment structures 320 coincide, or in other words, the extension lines of the movement trajectories of the two second adjustment structures 320 in the first direction coincide. In this arrangement, two second adjustment structures 320 are provided on both sides of the first bracket 100, respectively, and the four second adjustment structures 320 are respectively abutted against the opposite sides of the first bracket 100. During the process of adjusting the angle of the first bracket 100, Figure 4If the four second adjustment structures 320 are in the initial state, if the first bracket 100 is to be Figure 4 If the left adjustment seat 220 is rotated clockwise along the second axis L2, the second adjustment structure 320 located on the upper side of the left adjustment seat 220 and the second adjustment structure 320 located on the upper side of the right adjustment seat 220 will both move to the right, and the second adjustment structure 320 located on the lower side of the left adjustment seat 220 and the second adjustment structure 320 located on the lower side of the right adjustment seat 220 will both move to the left. The positions of the second adjustment structures 320 after the movement are as shown in FIG. Figure 5 As shown. Since the number of the second adjustment structures 320 provided on the two adjustment seats 220 is the same and their positions are opposite, during the manufacturing process, the manufacturing processes of the two adjustment seats 220 are the same or similar, which is convenient for design and manufacturing. This arrangement method uses a smaller number of second adjustment seats 220 to adjust the angle of the first bracket 100, which can not only improve the stability of the first bracket 100 during and after the angle adjustment, but also can be manufactured in a relatively simple and convenient processing method, and since the number of the second adjustment structures 320 is relatively small, the assembly efficiency is high.

[0056] In the above two adjustment seats 220, the second adjustment structure 320 in one of the adjustment seats 220 can also be replaced by an elastic structure, that is, a plurality of second adjustment structures 320 can be arranged on one of the adjustment seats 220, and a plurality of elastic structures can be arranged on the other adjustment seat 220, the elastic structure is located between the adjustment seat 220 and the first bracket 100, and one end of the elastic structure is in contact with the first bracket 100, and the elastic structure provides thrust for the first bracket 100, so that the first bracket 100 is in stable contact with the second adjustment structure 320 on the other adjustment seat 220, so that the first bracket 100 has a higher stability during the rotation process around the second axis L2, and when the first bracket 100 is not locked in the second bracket 200 by the locking structure 400, the two sides of the first bracket 100 are in a stable state under the action of the second adjustment structure 320 and the elastic structure respectively. The number of the elastic structures can be the same as the number of the second adjustment structures 320 and they are arranged one by one. The elastic structure can be a spring, a spring, a block structure made of an elastic material (such as rubber), etc.

[0057] The second adjustment structure 320 can move relative to the adjustment seat 220 in the first direction, and can be fixed relative to the adjustment seat 220 after the movement. Optionally, the second adjustment structure 320 and the adjustment seat 220 can be moved and fixed by threaded matching. Specifically, the second adjustment structure 320 includes a first thread segment, which is a structure with external threads in the second adjustment structure 320. The adjustment seat 220 is provided with a first threaded hole 330, and the first threaded hole 330 on the adjustment seat 220 matches the external threads in the second adjustment structure 320. By rotating the second adjustment structure 320, the first thread segment rotates relative to the first threaded hole 330. As the first thread segment rotates, the first thread segment also moves relative to the first threaded hole 330 in the first direction. The second adjustment structure 320 can be a bolt or a top screw. The bolt includes a head and a rod. The head of the bolt is not provided with external threads, and the rod is provided with external threads. The rod of the bolt is the first thread segment. The top screw is provided with external threads as a whole, and the top screw is the first thread segment as a whole. The second adjustment structure 320 can only include the first thread segment. When the second adjustment structure 320 is a top screw, one end of the top screw extends out of the first threaded hole 330 to abut against the first bracket 100, and the other end of the top screw is located inside the first threaded hole 330. The top screw can be inserted into the inside of the first threaded hole 330 through an auxiliary structure such as a screwdriver to rotate the top screw, so as to drive the first bracket 100 to rotate around the second axis L2 through the top screw. Since the end of the top screw away from the first bracket 100 does not extend outside the first threaded hole 330, less space is occupied outside the adjustment seat 220. The use of the first thread segment and the first threaded hole 330 to achieve the movement of the second adjustment structure 320 relative to the adjustment seat 220 along the first direction is also convenient for more accurate estimation of the adjustment angle. When the first thread segment rotates one circle, the distance moved by the first thread segment relative to the first threaded hole 330 is constant, so it is convenient to make more accurate angle adjustment of the first bracket 100. As can be seen from the above, the second adjustment structure 320 is moved and fixed relative to the adjustment seat 220 through the cooperation between the first threaded section and the first threaded hole 330 , and has a simple structure, a simple adjustment method, and high adjustment accuracy.

[0058] In addition to being moved and fixed relative to the adjustment seat 220 by means of threads, the second adjustment structure 320 may also be moved and fixed in other ways. For example, a first hole is provided along the first direction on the adjustment seat 220, and a second hole is provided along the second direction. The first hole is connected to the second hole. The first hole is a light hole, and the second hole is a threaded hole. The second adjustment structure 320 includes a sliding part and a positioning part. The positioning part is a bolt. The sliding part is inserted into the first hole, and the positioning part is screwed into the second hole. During the movement of the sliding part relative to the first hole, the positioning part does not contact the sliding part. After the sliding part moves into position, the positioning part is tightened, the positioning part abuts against the sliding part, and the sliding part abuts against the hole wall of the first hole, thereby fixing the sliding part on the adjustment seat 220.

[0059] In the adjustment device 1, the first adjustment structure 310 is used to drive the bracket to rotate around the first axis L1. The number of the first adjustment structure 310 can be one or more. When the number of the first adjustment structure 310 is one, an elastic structure can be provided on the second bracket 200 at a position symmetrical to the first adjustment structure 310 relative to the rotation center along the third direction. The elastic structure is installed on the second bracket 200 and contacts the first bracket 100. When the number of the first adjustment structure 310 is multiple, the elastic structure may not be provided. In this arrangement, at least two first adjustment structures 310 are installed on the first bracket 100 at intervals along the third direction. The first adjustment structure 310 can move relative to the first bracket 100 along the second direction, and the multiple first adjustment structures 310 are respectively in contact with the second bracket 200. Since the number of the first adjustment structure 310 is multiple, multiple different positions on the first bracket 100 can be abutted and supported by multiple first adjustment structures 310, so that the force on the first bracket 100 is more uniform, less likely to shake, and more stable.

[0060] In order to make the first bracket 100 obtain higher support stability and complete the angle adjustment more quickly, Figure 5 As shown, there are four first adjustment structures 310, which are distributed in a matrix on the first bracket 100, and two first adjustment structures 310 are installed on one side of the first bracket 100 along the first direction, and the other two first adjustment structures 310 are installed on the other side of the first bracket 100 along the first direction. Figure 5 In the direction shown, the moving directions and moving distances of the two first adjustment structures 310 located on the upper side are equal, and the moving directions and moving distances of the two first adjustment structures 310 located on the lower side are equal. Figure 6 and Figure 7 As shown, the first direction is the direction perpendicular to the paper surface. Figure 6 and Figure 7 In the embodiment, the sides of the first bracket 100 and the first base 210 in the second bracket 200 that are opposite to each other are parallel to the third direction, and there is an angle between the side of the first bracket 100 facing the first base 210 and the side of the first base 210 facing the first bracket 100, which is hereinafter referred to as the angle between the first bracket 100 and the first base 210. Figure 6 In the embodiment, the angle between the first bracket 100 and the first base 210 is β1. Figure 6 The first bracket 100 rotates counterclockwise around the first axis L1, and the first adjustment structure 310 located on the upper side is moved away from the first base 210 ( Figure 6The first adjustment structure 310 located at the lower side is moved toward the direction close to the first base 210 ( Figure 6 The first bracket 100 is driven to rotate to the left Figure 7 The status shown in Figure 7 , the angle between the first bracket 100 and the first base 210 is β2, the angle of rotation of the first bracket 100 around the first axis L1 is β3, β3 = β2-β1. Since the adjustable member 3 is mounted on the first bracket 100, the angle of rotation of the adjustable member 3 around the first axis L1 with the first bracket 100 is β3.

[0061] The first adjustment structure 310 can move relative to the first bracket 100 along the second direction, and can be fixed relative to the first bracket 100 after the movement. The first adjustment structure 310 can adopt the same structure as the second adjustment structure 320, or can adopt a different structure from the second adjustment structure 320. When the first adjustment structure 310 and the second adjustment structure 320 adopt the same structure, when the angle of the first bracket 100 is adjusted, the adjustment operation of the first adjustment structure 310 is the same or similar to the adjustment operation process of the second adjustment structure 320, which is conducive to improving the adjustment efficiency and facilitating the adjustment operation.

[0062] When the first adjustment structure 310 and the second adjustment structure 320 adopt the same structure, the first adjustment structure 310 and the second adjustment structure 320 may both adopt a structure having a first threaded section. For example, the first adjustment structure 310 and the second adjustment structure 320 respectively have a first threaded section, and the first bracket 100 and the adjustment seat 220 are respectively provided with a first threaded hole 330. The first threaded section of the first adjustment structure 310 is installed in the corresponding first threaded hole 330 on the first bracket 100, and the first threaded section of the second adjustment structure 320 is installed in the corresponding first threaded hole 330 on the adjustment seat 220. By rotating the first threaded section of the first adjustment structure 310, the first adjustment structure 310 can be moved relative to the corresponding first threaded hole 330, and by rotating the first threaded section of the second adjustment structure 320, the second adjustment structure 320 can be moved relative to the corresponding first threaded hole 330. In a specific example, each of the first adjustment structures 310 and each of the second adjustment structures 320 are top screws.

[0063] Of course, in other settings, the first adjustment structure 310 and the second adjustment structure 320 may also adopt other moving and fixing methods, such as the moving method of the second adjustment seat 220 described above including the sliding part and the positioning part, which will not be repeated here.

[0064] like Figure 1 and Figure 6As shown, the locking structure 400 is used to lock and fix the first bracket 100 and the second bracket 200. During the process of adjusting the angle of the first bracket 100 by the first adjustment structure 310 and the second adjustment structure 320, the locking structure 400 is in an unlocked state, so that the first bracket 100 and the second bracket 200 can rotate relative to each other. After the angle adjustment process of the first bracket 100 is completed, the locking structure 400 relatively fixes the positions of the first bracket 100 and the second bracket 200 to fix the angle of the first bracket 100 at the current angle. The locking structure 400 can relatively fix the first bracket 100 and the second bracket 200 by thread locking. Exemplarily, the locking structure 400 is provided with a second threaded section. In the first bracket 100 and the second bracket 200, one is provided with a first through hole 410, and the other is provided with a second threaded hole 420. One end of the locking structure 400 provided with the second threaded section passes through the second through hole and is screwed into the second threaded hole 420, and the other end of the locking structure 400 abuts against the bracket provided with the first through hole 410, thereby fixing the first bracket 100 and the second bracket 200. It is worth noting that the aperture of the first through hole 410 is larger than the aperture of the threaded hole, so that the first bracket 100 can be rotated relative to the second bracket 200 without completely unscrewing the locking structure 400 from the second threaded hole 420. It is worth noting that in order to simultaneously display the locking structure 400 and the second threaded hole 420 and the first through hole 410 used for installing the locking structure 400, only Figure 1 and Figure 6 A locking structure 400 is shown in each figure, and the first bracket 100 and the second bracket 200 can be connected and fixed by multiple locking structures 400.

[0065] When the first adjustment structure 310 is provided on the first bracket 100, the displacement operation of the first adjustment structure 310 can be located on the side of the first bracket 100 away from the second bracket 200 in the second direction. Therefore, in order to facilitate the locking and unlocking operations, the first through hole 410 is provided on the first bracket 100, the second threaded hole 420 is provided on the second bracket 200, the second threaded section is passed through the first through hole 410 and installed in the second threaded hole 420, and the aperture of the first through hole 410 is larger than the aperture of the threaded hole. In this arrangement, the locking and unlocking operations of the locking structure 400 are both performed on the side of the first bracket 100 away from the second bracket 200 in the second direction, which is on the same side as the displacement operation of the first adjustment structure 310, so as to facilitate the operation.

[0066] The first through hole 410 can be a straight hole or a countersunk hole. The locking structure 400 can be a bolt, which includes a head and a rod. The rod is the second threaded section. The head is connected to one side of the rod, and the outer diameter of the head is larger than the outer diameter of the rod. When the first through hole 410 is a straight hole, the outer diameter of the head is larger than the aperture of the first through hole 410. A part of the rod is screwed into the second threaded hole 420. The head is located outside the first through hole 410 and abuts against the outer area of ​​the first through hole 410 on the first bracket 100. Figure 6 As shown, when the first through hole 410 is a countersunk hole, the countersunk hole includes two sections of holes that are interconnected, one section is a small hole, and the other section is a large hole. The aperture of the small hole is larger than the aperture of the second threaded hole 420, and the aperture of the large hole is larger than the aperture of the small hole. The outer diameter of the head of the bolt is larger than the aperture of the small hole and smaller than the aperture of the large hole. When the locking structure 400 is in a locked state, the head of the bolt is completely located in the large hole and abuts against the step surface formed between the large hole and the small hole. In this arrangement, the locking structure 400 does not extend out of the outside of the first through hole 410 when it is in a locked state, so it does not occupy the space on the side of the first bracket 100 away from the second bracket 200, which is convenient for the installation of the part 3 to be adjusted.

[0067] It is worth noting that after the locking structure 400 passes through the first through hole 410 and is screwed into the second threaded hole 420, when the locking structure 400 does not abut against the first bracket 100, the locking structure 400 is in an unlocked state. Although the locking structure 400 has not completely disengaged from the second threaded hole 420, the second threaded segment of the locking structure 400 matches the second threaded hole 420, and the aperture of the second threaded hole 420 is smaller than the aperture of the first through hole 410. Therefore, there is a certain gap between the area where the second threaded segment is located in the first through hole 410 and the inner wall of the first through hole 410. The existence of this gap enables the first bracket 100 to rotate within a certain range relative to the second bracket 200 when the locking structure 400 is still located in the first through hole 410, so as to achieve angle adjustment of the first bracket 100. Since the locking structure 400 is located in the first through hole 410, the locking structure 400 also plays a certain supporting role for the first bracket 100, that is, even if no other structure for limiting is provided between the first bracket 100 and the second bracket 200, the provision of the locking structure 400 can provide limiting and supporting functions within a certain range for the first bracket 100 and the second bracket 200, and enable the first bracket 100 and the second bracket 200 to rotate relative to each other within the limiting range of the locking structure 400. After the locking structure 400 is further screwed into the second threaded hole 420, the locking structure 400 abuts against the first bracket 100, thereby locking the first bracket 100 and the second bracket, so that the first bracket 100 and the second bracket 200 are relatively fixed in the locked state and cannot rotate relative to each other.

[0068] like Figure 8 and Fig. 9 As shown, the first bracket 100 is used to limit or fix the adjustable member 3 to a certain extent, so that the adjustable member 3 can rotate with the first bracket 100 to achieve angle adjustment. In order to facilitate the installation and fixation of the adjustable member 3, the first bracket 100 includes a second base 110 and a first bearing seat 120, and the first bearing seat 120 includes a first clamping portion 121 and a second clamping portion 122. The first clamping portion 121 is installed on the second base 110, and the first clamping portion 121 and the second clamping portion 122 are detachably connected. The first clamping portion 121 and the second clamping portion 122 are surrounded to form a first clamping area 123, and the first clamping area 123 is used to clamp the adjustable member 3. When installing the part 3 to be adjusted, the first clamping portion 121 is separated from the second clamping portion 122, the part 3 to be adjusted is placed between the first clamping portion 121 and the second clamping portion 122, and the first clamping portion 121 is connected to the second clamping portion 122, so that the part 3 to be adjusted is clamped in the first clamping area 123. Since the first clamping portion 121 and the second clamping portion 122 are detachably connected, the first clamping portion 121 and the second clamping portion 122 can be separated during the installation of the part 3 to be adjusted, so that the opening of the first clamping area 123 for the part 3 to be adjusted to enter is larger, which is convenient for placing the part 3 to be adjusted in the first clamping area 123, and it is easy to make the size of the first clamping area 123 domain and the part 3 to be adjusted more adaptable, so that the contact area between the first clamping portion 121 and the second clamping portion 122 and the part 3 to be adjusted can be larger, which is convenient for fixing the part 3 to be adjusted more firmly.

[0069] The first clamping portion 121 is fixed on the second base 110. The first clamping portion 121 and the second base 110 can be connected by welding, gluing, etc., or by bolts, screws, etc. The first clamping portion 121 and the second base 110 can also be an integral structure manufactured by an integral molding method. Exemplarily, the first clamping portion 121 and the second clamping portion 122 can be connected by bolts. When the first adjustment structure 310 is installed on the first bracket 100, the first adjustment structure 310 can be installed on the second base 110. When the locking structure 400 includes a second threaded section and a first through hole 410 is opened on the first bracket 100, the first through hole 410 can be set on the second base 110.

[0070] The first bracket 100 clamps and fixes the adjustable member 3 through the first bearing seat 120. In order to improve the fixing effect of the first bracket 100 on the adjustable member 3, as shown in FIG. Fig.10As shown, the first bracket 100 also includes a positioning seat 130, which is installed on the second base 110. The positioning seat 130 is spaced apart from the first bearing seat 120. The positioning seat 130 is provided with a positioning hole 131, which is arranged opposite to the first clamping area 123. The positioning hole 131 is used to accommodate a part of the structure of the part to be adjusted 3. When the part to be adjusted 3 passes through the positioning seat 130, the inner wall of the positioning hole 131 is arranged around the outer periphery of a part of the part to be adjusted 3, thereby playing a certain role in limiting the part to be adjusted 3. Figure 2 and Fig.10 As shown, the positioning hole 131 is coaxially arranged with the first clamping area 123, and the positioning hole 131 and the first clamping area 123 are spaced apart in the third direction. When the part 3 to be adjusted is a line scan camera, the positioning hole 131, the first clamping area 123 and the third axis L3 are coaxially arranged, the lens of the line scan camera passes through the positioning hole 131 and the first clamping area 123, the first bearing seat 120 clamps and fixes the lens of the line scan camera in the area within the first clamping area 123, and the positioning seat 130 limits the lens of the line scan camera in the radial direction, thereby reducing the shaking of the line scan camera relative to the first bracket 100 and improving the positioning effect of the line scan camera on the first bracket 100.

[0071] The first bracket 100 can be used to fix one to-be-adjusted member 3, or can be used to fix multiple to-be-adjusted members 3. When the first bracket 100 is used to fix one to-be-adjusted member 3, the number of the first bearing seat 120 is one. When the first bracket 100 is used to fix multiple to-be-adjusted members 3 at the same time, the number of the first bearing seats 120 can be multiple, and the multiple first bearing seats 120 can be arranged on the second base 110 along the first direction at intervals.

[0072] In addition to providing a plurality of first bearing seats 120, a second bearing seat 140 may be provided in the first bracket 100, and different adjustable parts 3 may be fixed by the first bearing seat 120 and the second bearing seat 140, respectively. Fig.10As shown, the first bracket 100 also includes a second bearing seat 140, and the second bearing seat 140 includes a second clamping area 141, and the second clamping area 141 is spaced apart from the first clamping area 123. The first bearing seat 120 can clamp and fix one to-be-adjusted member 3 through the first clamping area 123, and the second bearing seat 140 can clamp and fix another to-be-adjusted member 3 through the second clamping area 141. The first clamping area 123 and the second clamping area 141 can be of different sizes. For example, the first clamping area 123 and the second clamping area 141 are both cylindrical holes, and the aperture of the first clamping area 123 is larger than the aperture of the second clamping area 141, then the first clamping area 123 and the second clamping area 141 can be used to clamp the to-be-adjusted members 3 of different sizes, respectively. The first clamping area 123 and the second clamping area 141 are spaced apart. For example, the first clamping area 123 and the second clamping area 141 are spaced apart in the second direction, and the first clamping area 123 and the second clamping area 141 are spaced apart in the third direction. Fig.10 In the direction shown, the maximum distance between the first clamping area 123 and the second base 110 is smaller than the minimum distance between the second clamping area 141 and the second base 110. If being close to the second base 110 is considered close and being far away from the second base 110 is considered far, the second clamping area 141 is located further away from the second base 110 than the first clamping area 123. Fig.10 In the embodiment, the second bearing seat 140 is located at a side of the positioning seat 130 away from the second base 110, the second bearing seat 140 can be integrated with the positioning seat 130, a recessed structure is provided at a side of the positioning seat 130 away from the second base 110, the second bearing seat 140 includes a third clamping portion 142, the third clamping portion 142 is provided with a recessed structure opposite to the positioning seat 130, the third clamping portion 142 is detachably connected to the positioning seat 130, after the third clamping portion 142 is connected to the positioning seat 130, the recessed structure of the third clamping portion 142 is connected to the recessed structure of the positioning seat 130 to form a second clamping area 141. This arrangement makes the structure of the first bracket 100 more compact.

[0073] like Fig.10As shown, an avoidance groove 124 can be set at the position where the first bearing seat 120 and the second clamping area 141 are opposite to each other, and the part to be adjusted 3 is fixed on the second bearing seat 140, and part of the structure of the part to be adjusted 3 is located in the avoidance groove 124. The setting of the avoidance groove 124, on the one hand, can play a certain limiting role for the part to be adjusted 3 installed on the second bearing seat 140, and on the other hand, the second clamping area 141 can be set at a position closer to the second base 110, so that the size of the first bracket 100 in the second direction is smaller. After the part to be adjusted 3 is installed, the center of gravity of the first bracket 100 and the part to be adjusted 3 can be relatively closer to the second base 110, thereby improving the structural stability of the first bracket 100 and the part to be adjusted 3, and reducing the shaking of the first bracket 100 and the part to be adjusted 3 installed thereon.

[0074] The part to be adjusted 3 may be a camera. When the camera is in use, it needs to be focused first. To facilitate the focusing operation of the camera, the adjustment device 1 also includes a driving structure 500. The driving structure 500 is connected to the second bracket 200. The driving structure 500 is used to drive the second bracket 200 to move along the third direction, and the third direction is perpendicular to the first direction and the second direction respectively. The second bracket 200 is driven to move along the third direction by the driving structure 500, thereby driving the first bracket 100 and the part to be adjusted 3 on the first bracket 100 to move along the third direction. When the part to be adjusted 3 is a line scan camera, the line scan camera is driven to move along the third direction by the driving structure 500, which is conducive to the line scan camera focusing on the objects on the stage, so that the image obtained by the line scan camera has higher clarity.

[0075] The driving structure 500 is a structure for driving the second bracket 200 to move along the third direction, and the driving structure 500 may be an electric driving structure 500, a pneumatic structure, or a hydraulic driving structure 500. For example, the driving structure 500 may be a linear motor, a cylinder, or any other structure capable of driving the second bracket 200 to move linearly.

[0076] Combined with Fig. 9 and Fig.11When the driving structure 500 is a linear motor, the driving structure 500 may include a fixed portion 510 and a moving portion 520, wherein the fixed portion 510 is fixed relative to the stage, and the moving portion 520 is connected to the second bracket 200. The moving portion 520 is movably mounted on the fixed portion 510, and the moving portion 520 can move relative to the fixed portion 510 along the third direction, and the second bracket 200 is driven to move along the third direction by the moving portion 520. The fixed portion 510 may be fixedly connected to the ground or a table, or the fixed portion 510 may be fixed to other structures fixed relative to the ground or a table. Exemplarily, the adjustment device 1 is applied in an industrial production line, and the industrial production line includes a frame, and the fixed portion 510 may be directly mounted on the frame, or a support frame 2 is mounted on the frame, and the fixed portion 510 is fixedly connected to the support frame 2. Of course, the adjustment device 1 may also include a support frame 2, and the fixed portion 510 is fixedly mounted on the support frame 2, and the support frame 2 may be directly connected to the ground, or the support frame 2 may be connected to a frame in the industrial production line. When the part to be adjusted 3 is a line scan camera, a stage is usually provided on the frame, and the product to be inspected is placed on the stage, and the line scan camera is used to detect the product to be inspected. In the driving structure 500, the fixed part 510 is fixed relative to the frame, and the movable part 520 can move along the third direction relative to the fixed part 510. Since the movable part 520 is connected to the second bracket 200, the movable part 520 can drive the second bracket 200 to move along the third direction, so that the second bracket 200 can move relative to the stage, so that the first bracket 100 and the part to be adjusted 3 on the first bracket 100 are both moved relative to the stage. The movable part 520 and the second bracket 200 can be fixedly connected by screwing, clamping, welding or other methods.

[0077] In order to facilitate the movable part 520 to move more stably along the third direction relative to the fixed part 510, the adjustment device 1 may further include a slide rail 530 and a slider 540. The slide rail 530 is fixedly mounted on the support frame 2, and the slider 540 is movably mounted on the slide rail 530. The slider 540 is connected to the movable part 520, and the slide rail 530 extends along the third direction, and the slider 540 can move along the slide rail 530. The slide rail 530 cooperates with the slider 540 to make the movable part 520 move more stably along the third direction, thereby making the second bracket 200, the first bracket 100, and the to-be-adjusted member 3 on the first bracket 100 move more stably along the third direction.

[0078] When the part 3 to be adjusted is a line scan camera, the distance between the line scan camera and the stage is usually within a set range. In order to limit the maximum movement range of the part 3 to be adjusted along the third direction, the adjustment device 1 further includes a first sensor 610, a second sensor 620 and a trigger 630, the trigger 630 is connected to the second bracket 200, the first sensor 610 and the second sensor 620 are arranged at intervals along the third direction, the trigger 630 is used to trigger the first sensor 610 and the second sensor 620, the first sensor 610 and the second sensor 620 are connected to the drive structure 500 by signal, and the drive structure 500 is used to stop driving the second bracket 200 to move when one of the first sensor 610 and the second sensor 620 is triggered. When the second bracket 200 moves along the third direction driven by the drive structure 500, the trigger 630 is also driven to move along the third direction. Since the first sensor 610 and the second sensor 620 are arranged at intervals along the third direction, and when the trigger 630 triggers the first sensor 610 or the second sensor 620, the driving structure 500 stops driving the second bracket 200 to move, therefore, the trigger 630 can only move between the first sensor 610 and the second sensor 620. It can be seen from this that the first sensor 610 and the second sensor 620 can limit the maximum range of movement of the trigger 630 along the third direction. Since the trigger 630 is connected to the second bracket 200, the first sensor 610 and the second sensor 620 can also limit the maximum range of movement of the second bracket 200 along the third direction, thereby limiting the maximum range of movement of the part to be adjusted 3 along the third direction. The trigger 630 can be connected to the second bracket 200 by screwing, clamping, welding or other methods. Exemplarily, the first sensor 610 is used to limit the maximum range of movement of the trigger 630 in the direction away from the stage, so that the line scan camera performs a focusing operation on the part to be detected on the stage. The second sensor 620 is used to limit the maximum range of movement of the trigger 630 in the direction close to the stage, so as to avoid the collision between the line scan camera and the object to be inspected on the stage to a certain extent.

[0079] The first sensor 610 and the second sensor 620 may be contact sensors, proximity sensors, or other sensors that can be triggered by the trigger 630. The structures of the first sensor 610 and the second sensor 620 may be the same or different. In some examples, the first sensor 610 and the second sensor 620 are both proximity sensors. For example, the first sensor 610 and the second sensor 620 are both photoelectric sensors.

[0080] The driving structure 500 is used to drive the first bracket 100, the second bracket 200 and the adjustable member 3 to move along the third direction, that is, the driving structure 500 provides the first bracket 100, the second bracket 200 and the adjustable member 3 with a driving force to move along the third direction. In order to reduce the load of the driving structure 500, as shown in FIG. Fig.12 As shown, the adjustment device 1 also includes a balancing structure 700, which is connected to the second bracket 200, and the balancing structure is used to apply a force to the second bracket 200 to overcome the gravity. It is worth noting that the balancing structure can also be used to apply a force to the second bracket 200, the first bracket 100 and the member to be adjusted 3 as a whole to overcome the gravity, that is, the force applied by the balancing structure to the second bracket 200 to overcome the gravity can be greater than the gravity of the second bracket 200, but not more than the total gravity of the first bracket 100, the second bracket 200 and the member to be adjusted 3 installed on the first bracket 100. It can be seen that by setting the balancing structure, at least part of the weight of the first bracket 100 and the second bracket 200 can be borne, so as to reduce the weight of the first bracket 100 and the second bracket 200 borne by the driving structure 500, and to a certain extent, the service life of the driving structure 500 can be improved. Moreover, in the above-mentioned setting, the driving structure 500 applies a force on the second bracket 200 that is less than the total gravity of the first bracket 100, the second bracket 200 and the part to be adjusted 3, thereby driving the second bracket 200, the first bracket 100 and the part to be adjusted 3 to move along the third direction, thereby reducing the driving force required to be provided by the driving structure 500, thereby reducing the energy consumption of the driving structure 500 to a certain extent.

[0081] The balancing structure 700 may include a first balancing member 710 and a second balancing member 720, and the first balancing member 710 and the second balancing member 720 are respectively connected to the upward facing side wall and the downward facing side wall of the second bracket 200. Exemplarily, the first balancing member 710 is connected to the upward facing side wall of the second bracket 200, and the second balancing member 720 is connected to the downward facing side wall of the second bracket 200. The first balancing member 710 and the second balancing member 720 are both installed on the support frame 2, and the first balancing member 710 exerts a pulling force to overcome gravity on the second bracket 200, and the second balancing member 720 exerts a supporting force to overcome gravity on the second bracket 200. Such an arrangement can effectively reduce the weight of the first bracket 100 and the second bracket 200 borne by the driving structure 500.

[0082] Combination Fig.12 The first balancing member 710 can be a cylinder, which includes a cylinder body and a piston. The cylinder body is mounted on the support frame 2, one end of the piston is movably mounted in the cylinder body, and the other end of the piston abuts against the second bracket 200. Optionally, the piston can also be connected to the second bracket 200. The piston specifically abuts against the side wall of the second bracket 200 facing downward, and the piston can move along the third direction relative to the cylinder body. In the process of the driving structure 500 driving the second bracket 200 to move along the third direction, the piston and the second bracket 200 move in the same direction.

[0083] The number of cylinders can be multiple, such as Fig.12As shown, the number of cylinders is two, and the two cylinders are arranged at intervals along the first direction. The second bracket 200 also includes a crossbeam 230, and the crossbeam 230 is connected to the first base 210. In the first direction, the length of the crossbeam 230 is greater than the length of the first base 210, and the two ends of the crossbeam 230 protrude from the opposite sides of the first base 210 in the first direction. The two cylinders are respectively located on the opposite sides of the first base 210 along the first direction, one of the cylinders is located below one end of the crossbeam 230, and the other cylinder is located below the other end of the crossbeam 230, and the pistons of the two cylinders are respectively abutted against the bottom wall of the crossbeam 230. By providing two cylinders, the support stability of the second bracket 200 is improved.

[0084] The above-mentioned second balancing member 720 can be an elastic member, and the elastic member is made of an elastic material. For example, the elastic member is a spring, which can be a compression spring or a tension spring. Taking the elastic member as a tension spring as an example, one end of the tension spring is mounted on the support frame 2, and the other end is connected to the second bracket 200. Specifically, a first mounting seat is provided on the support frame 2, one end of the tension spring is mounted on the first mounting seat, and the tension spring is mounted on the support frame 2 through the first mounting seat. The other end of the tension spring is specifically connected to the crossbeam 230 of the second bracket 200, and the tension spring can exert an upward pulling force on the crossbeam 230 to overcome at least part of the gravity of the second bracket 200 and the first bracket 100.

[0085] The number of the tension springs can also be multiple. Fig.12 In the figure, there are two tension springs (one tension spring is blocked by the to-be-adjusted member 3 and is not shown due to the viewing angle of the figure), and the two tension springs are arranged at intervals along the third direction. The two tension springs are respectively connected to the top wall of the crossbeam 230. By providing two tension springs, it is beneficial to improve the installation stability of the second bracket 200.

[0086] The adjusting device 1 may also include a limiting structure 800, and the second bracket 200 is provided with the limiting structure 800 on both sides of the third direction, and the limiting structure 800 is arranged at intervals with the second bracket 200. By respectively arranging the limiting structure 800 on both sides of the second bracket 200 along the third direction, the maximum movement range of the part to be adjusted 3 along the third direction can also be limited. Taking the third direction as the vertical direction as an example, the limiting structure 800 is respectively arranged on the upper and lower sides of the second bracket 200. When the second bracket 200 moves vertically upward, the first bracket 100 and the part to be adjusted 3 on the first bracket 100 also move upward at the same time, until the second bracket 200 abuts against the limiting structure 800 on the upper side, so that the second bracket 200 cannot continue to move upward, thereby limiting the maximum distance between the part to be adjusted 3 and the stage. When the second bracket 200 moves vertically downward, the minimum distance between the part to be adjusted 3 and the stage is limited by the limiting structure 800 on the lower side of the second bracket 200.

[0087] like Fig.12 As shown, the above-mentioned limiting structure 800 may include a second mounting seat 810 and a buffer 820, the second mounting seat 810 is mounted on the support frame 2, and the buffer 820 is mounted on the second mounting seat 810. The buffer 820 is made of a flexible material, such as rubber or silicone. When the second bracket 200 abuts against the limiting structure 800, the second bracket 200 specifically abuts against the buffer 820 in the limiting structure 800. Since the buffer 820 is made of a flexible material, it can play a certain buffering and protective role on the second bracket 200.

[0088] The number of the above-mentioned limiting structures 800 can be multiple. For example, the number of limiting structures 800 is four, of which two limiting structures 800 are located on one side of the second bracket 200 in the third direction and are arranged at intervals, and the other two limiting structures 800 are located on the other side of the second bracket 200 in the third direction and are arranged at intervals. In this way, when the second bracket 200 abuts against the two limiting structures 800 on one side, the two limiting structures 800 can provide more stable support for the second bracket 200, so that the limiting effect of the second bracket 200 is better.

[0089] It is understandable that the adjustment device 1 may include a first sensor 610, a second sensor 620, a trigger 630 and a limiting structure 800 at the same time. The first sensor 610, the second sensor 620 and the trigger 630 are arranged so that the adjustment device 1 can limit the maximum range of movement of the second bracket 200 along the third direction by controlling the driving of the driving motor. The arrangement of the limiting structure 800 plays a more effective role in limiting the movement range of the second bracket 200 in the third direction, thereby making the adjustment device 1 more reliable in limiting the movement range of the to-be-adjusted member 3 in the third direction. For example, when the signal transmission between the first sensor 610 and the second sensor 620 and the driving structure 500 fails, the maximum movement range of the second bracket 200 in the third direction can also be limited by the limiting structure 800.

[0090] The present application also provides a camera assembly, which includes a camera and an adjustment device 1 provided in any of the above embodiments, wherein the camera is mounted on a first bracket 100 of the adjustment device 1. In the adjustment device 1, the first bracket 100 can rotate relative to the second bracket 200 around a first axis L1 and a second axis L2. The camera is mounted on the first bracket 100, so the angle of the camera can be adjusted by rotating the first bracket 100. Figure 2As shown, in a specific example, the axis of the camera lens is the third axis L3, the first axis L1 extends along the first direction, the second axis L2 extends along the second direction, and the third axis L3 extends along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. Taking the first direction as the left-right direction, the second direction as the front-back direction, and the third direction as the up-down direction as an example, the first bracket 100 is rotated around the first axis L1 to adjust the pitch angle (or front-back tilt angle) of the camera, and the first bracket 100 is rotated around the second axis L2 to adjust the left-right tilt angle of the camera. When a driving structure 500 is provided in the adjustment device 1, the second bracket 200, the first bracket 100 and the camera can be driven to move up and down by the driving structure 500 to facilitate the camera to focus. The camera can be a line scan camera, an array camera, etc. Since the line scan camera has higher requirements for the installation angle, it is more suitable to be installed on the adjustment device 1. The pitch angle and the left and right tilt angle of the line scan camera can be adjusted by the adjustment device 1, so that the flatness of the line scan camera can be adjusted to improve the quality of the image collected by the line scan camera and reduce the problem of the angle of the line scan camera not reaching the preset angle after installation due to manufacturing errors or assembly errors.
