[0045] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] In addition, in the utility model, the connection between two objects may refer to the connection and contact between the two objects, or it may refer to the two objects not being in direct contact, in which case the two objects are connected through an intermediate object.

[0047] like Figure 1 As shown, in one embodiment, the detection device 100 includes a support module 10 and a camera module 20, wherein the camera module 20 is connected to the support module 10 and is used to take pictures of the object to be tested. In addition, the detection device 100 also includes a processing module, which is used to process the image taken by the camera module 20 to determine whether the appearance of the object to be tested meets the requirements.

[0048] like Figures 1 to 4 As shown, in one embodiment, the support module 10 includes a first support component 1, a second support component 2 and a first drive component 3. The first support component 1 is used to connect to the camera module 20, and the first support component 1 and the second support component 2 are rotatably connected with the first axis as the axis; the first drive component 3 is used to drive the first support component 1 or the second support component 2, so that the first support component 1 and the second support component 2 can rotate relative to each other with the first axis as the axis. Figure 1 and Figure 2 In the illustrated embodiment, the first axis is parallel to the X-axis.

[0049] When the first driving component 3 directly drives the first supporting component 1 to rotate relative to the second supporting component 2 around the first axis (the second supporting component 2 can be regarded as stationary at this time), it can drive the camera module 20 connected to the first supporting component 1 to rotate around the first axis, thereby adjusting the shooting angle of the camera module 20 when shooting the object to be measured. When the first driving component 3 directly drives the second supporting component 2 to rotate relative to the first supporting component 1 around the first axis (the first supporting component 2 can be regarded as stationary at this time), if the object to be measured is placed on the second supporting component 2 or the corresponding supporting object connected to the second supporting component 2, the second supporting component 2 can drive the object to be measured to rotate relative to the camera module 20 connected to the first supporting component 1 around the first axis, so that the shooting angle of the camera module 20 when shooting the object to be measured can also be adjusted.

[0050] In addition, after the camera module 20 is connected to the first support assembly 1, the optical axis of the camera module 20 is not parallel to the first axis, wherein the angle between the optical axis of the camera module 20 and the first axis is greater than or equal to 70 degrees and less than or equal to 110 degrees. In this way, when the camera module 20 rotates around the first axis, its shooting angle can be adjusted. The optical axis of the camera module 20 is the axis of the lens of the camera module 20.

[0051] Preferably, the optical axis of the camera module 20 is perpendicular to the first axis.

[0052] Through the arrangement of this embodiment, it is possible to adjust the shooting angle of the camera module 20 when shooting the object to be measured, thereby improving the adaptability of the camera module 20 to different detection requirements.

[0053] In addition, the first axis may be perpendicular to the arrangement direction of the first support assembly 1 and the second support assembly 2. In one application scenario, the first support assembly 1 and the second support assembly 2 may be arranged along the front-to-back direction, and the first axis extends along the left-to-right direction. When the first support assembly 1 drives the camera module 20 to rotate, the optical axis of the camera module 20 can rotate to be parallel to the vertical direction.

[0054] like Figure 2 and Figure 3As shown, in one embodiment, the first driving assembly 3 includes a first adjusting rod 31, a first mounting seat 32 and a rotating structure 33; the first mounting seat 32 is connected to the second supporting assembly 2, the first mounting seat 32 is provided with a first connecting through hole, and the second supporting assembly 2 is provided with a second connecting through hole corresponding to the first connecting through hole; the first adjusting rod 31 passes through the first connecting through hole and the second connecting through hole in sequence; the two ends of the rotating structure 33 are respectively connected to the first adjusting rod 31 and the first supporting assembly 1; when the first adjusting rod 31 moves along its axial direction, the first adjusting rod 31 can drive the rotating structure 33 to rotate, and then drive the first supporting assembly 1 to rotate around the first axis. The rotating structure 33 can adjust the direction of force transmission, and the setting of the rotating structure 33 can make it more convenient for the first adjusting rod 31 to apply force to the first supporting assembly 1.

[0055] The axis of the first adjustment rod 31 is not parallel to the optical axis of the camera module 20. Figure 2 and Figure 3 In the illustrated embodiment, the axis of the first adjustment rod 31 is parallel to the Y-axis, wherein the Y-axis is perpendicular to the X-axis.

[0056] It should be understood that the force application point of the first adjusting rod 31 on the first supporting assembly 1 through the rotating structure 33 is spaced a certain distance from the first axis.

[0057] like Figure 3 As shown, in one embodiment, the first adjustment rod 31 includes a first connecting rod 311 and a first manual force-applying member 312, the first connecting rod 311 passes through the first connecting through hole and the second connecting through hole in sequence, one end of the first connecting rod 311 is connected to the first manual force-applying member 312, and the other end of the first connecting rod 311 is connected to the rotating structure 33. The operator can manually apply force to the first manual force-applying member 312, thereby driving the first connecting rod 311 to move along the axis of the first connecting rod 311, so that the rotating structure 33 can be driven to rotate, and then the first support assembly can be driven to rotate around the first axis. Among them, the axis of the first connecting rod 311 is the axis of the first adjustment rod 31. That is, in this embodiment, the first adjustment rod 31 can be driven to move along its own axis direction manually.

[0058] In addition, the first connecting through hole can be through the first mounting seat 32 along the axial direction of the first adjusting rod 31, and the second connecting hole can be through the second supporting assembly 2 along the axis of the first adjusting rod 31. The second connecting hole plays a avoidance role to prevent the second supporting assembly from interfering with the movement of the first adjusting rod 31.

[0059] like Figure 5As shown, in one embodiment, the rotating structure 33 includes a first connecting portion 331 and a second connecting portion 332 that are rotatably connected; the first connecting portion 331 is connected to the first adjusting rod 31, and the second connecting portion 332 is connected to the first supporting assembly 1. Specifically, the first connecting portion 331 can be connected to an end of the first connecting rod 311 away from the first manual force applying member 312.

[0060] In one embodiment, an internal thread is provided on the inner surface of the first connecting hole, that is, along the axial direction of the first connecting hole, at least a part of the first connecting hole is a threaded hole; an external thread is provided on the first adjusting rod 31, that is, along the axial direction of the first adjusting rod 31, at least a part of the first adjusting rod 31 is a stud, and the stud part of the first adjusting rod 31 is threadedly matched with the threaded hole part of the first connecting hole, and the first adjusting rod 31 can be driven to move along its axial direction by rotating the first adjusting rod 31. In addition, the stud part is actually located on the first connecting rod 311, and the first manual force applying member 312 can be a hand wheel. In addition, in this embodiment, the rotating structure 33 is a universal structure, and one of the first connecting part 331 and the second connecting part 332 can be universally rotated relative to the other.

[0061] like Figure 1 and Figure 4 As shown, in one embodiment, the first support component 1 is provided with a first assembly hole 1a, and the second support component 2 is provided with a second assembly hole 2a matching the first assembly hole 1a; the fastener 4 can be inserted into the first assembly hole 1a and the second assembly hole 2a.

[0062] When the fastener 4 is inserted into the first assembly hole 1a and the second assembly hole 2a, the first support assembly 1 and the second support assembly 2 can be fixed or loosened. When the fastener 4 fixes the first support assembly 1 and the second support assembly 2, the first support assembly 1 and the second support assembly 2 cannot rotate relative to each other around the first axis; when the fixing assembly 4 loosens the first support assembly 1 and the second support assembly 2, the first support assembly 1 and the second support assembly 2 can rotate relative to each other around the first axis.

[0063] like Figure 1 As shown, in one embodiment, at least one of the first assembly hole 1a and the second assembly hole 2a is an arc-shaped hole; wherein the axis of the arc-shaped hole is the first axis.

[0064] In a feasible embodiment, the first assembly hole 1a is an arc-shaped hole, and the second assembly hole 2a is a threaded hole. In this case, the fastener 4 can be a locking bolt, and the fastener 4 passes through the first support assembly 1 from the first assembly hole 1a and then is threadedly matched with the second assembly hole 2a. By adjusting the depth of the fastener 4 screwed into the second assembly hole 2a, the first support assembly 1 and the second support assembly 2 can be fixed or loosened.

[0065] In another feasible embodiment, the first assembly hole 1a is an arc-shaped hole, and the second assembly hole 2a is a through hole that passes through the second support component 2 along the first axis. In this case, the fastener 4 may include a locking bolt and a nut. The locking bolt passes through the first support component 1 from the first assembly hole 1a, and passes through the second support component 2 from the second assembly hole 2a, and the locking bolt and the nut are threadedly matched. The first support component 1 and the second support component 2 can be fixed or loosened by the matching of the locking bolt and the nut.

[0066] In one embodiment, the arc angle of the arc-shaped hole is 10 degrees to 20 degrees. For example, the arc angle may be 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees or 20 degrees.

[0067] In one embodiment, the number of arc holes is two, and the two arc holes are arranged at intervals along the radial direction of the midpoint of the arc holes, wherein the "radial direction of the midpoint of the arc holes" refers to the extension direction of the radius passing through the midpoint of the two arc holes, and the radius is the radius of the arc holes. In addition, "the two arc holes are arranged at intervals along the radial direction of the midpoint of the arc holes" can also be understood as: the two arc holes are arranged at intervals along the direction perpendicular to the first axis, and the two arc holes are symmetrical with respect to the same plane. Among them, "the two arc holes are symmetrical with respect to the same plane" means that when one arc hole is divided into two mirror-symmetrical parts by the first plane, the other arc hole is also divided into two mirror-symmetrical parts by the first plane.

[0068] In addition, when there are two arc-shaped holes, the number of the assembly holes corresponding to the arc-shaped holes can also be two.

[0083] In one embodiment, the first guide structure 53 is a guide groove provided on the upper surface of the third support plate 51, and the guide groove extends along the first direction; the second guide structure 25 is a guide block connected to the bearing plate 23. In addition, two guide grooves and two guide blocks are provided, one guide groove and one guide block cooperate, and the two guide grooves are spaced apart along the first axis.

[0084] like Figure 3 As shown, the first drive assembly 3 and the second drive assembly 6 are both connected to the side of the second support plate 21 away from the first support plate 11 , which facilitates the connection and adjustment of the first drive assembly 3 and the second drive assembly 6 .

[0085] like Figure 3 As shown, in one embodiment, the second driving assembly 6 includes a second adjusting rod 61 and a second mounting seat 62, the second mounting seat 62 is connected to the third supporting assembly 5, and the second mounting seat 62 is provided with a third connecting hole, the second adjusting rod 61 passes through the third connecting hole, and when the second adjusting rod 61 moves along its own axis, it can apply force to the second supporting assembly 2 to drive the second supporting assembly 2 to move along the first direction.

[0086] In addition, the third connecting hole can be a second threaded hole, and the second adjusting rod 61 has a stud, which is threadedly engaged with the third connecting hole. When the second adjusting rod 61 rotates around its own axis relative to the second mounting seat 62, the second adjusting rod 61 can apply force to the second support assembly 2 to drive the second support assembly 2 to move in the first direction.

[0087] The second mounting seat 62 may be connected to the upper surface of the third support plate 51 , the third connecting hole penetrates the second mounting seat 62 along the first direction, and the second adjusting rod 61 passes through the second mounting seat 62 from the third connecting hole and contacts the second support assembly 2 .

[0088] In addition, if Figure 3 As shown, the second adjustment rod 61 includes a second connecting rod 611 and a second manual force-applying member 612, the second connecting rod 611 is the stud portion of the first adjustment rod, the second manual force-applying member 612 is connected to one end of the second connecting rod 611, the second connecting rod 611 is threadedly matched with the third connecting hole, the axis of the second connecting rod 611 is the axis of the second adjustment rod 61, and the second connecting rod 611 can apply force to the second support assembly 2 when rotating around its own axis to drive the second support assembly 2 to move in the first direction. The second manual force-applying member 612 can also be a hand wheel, which is coaxial with the second connecting rod 611.

[0089] like Figure 3 As shown, the second support assembly 2 also includes a first stop block 26, which is connected to the second support plate 21. A through hole is provided on the first stop block 26, and the through hole penetrates the first stop block 26 along the first direction. The end of the second connecting rod 611 away from the second manual force member 612 passes through the first stop block 26 from the through hole. The end of the second connecting rod 611 away from the second manual force member 612 is provided with a second stop. When the second connecting rod 611 moves in the direction from the second stop block to the second manual force member 612, the second stop block can interfere with the first stop block 26 to drive the second force assembly to move along the first direction.

[0090] In addition, the second support plate 21 is provided with a connection hole 211, which penetrates the second support plate 21 along the direction from the second support plate 21 to the third support plate 51, and the third support plate 51 is provided with a third threaded hole 511. The support module 10 also includes a connection bolt, which passes through the second support plate 21 from the connection hole 211 and then is threadedly engaged with the third threaded hole 511, so that the second support plate 21 and the third support plate 51 can be locked together. The connection hole 211 is a long hole extending along the first direction.

[0091] like Figure 3 As shown, the second support plate 21 is provided with an avoidance groove 212, which is arranged on the surface of the second support plate 21 facing away from the first support plate 11, and the avoidance groove 212 passes through the second support plate 21 along the arrangement direction of the second support assembly 2 and the third support assembly 5. When the second support assembly 2 moves along the first direction, the second mounting seat 62 can enter the avoidance groove 212.

[0092] like Figure 3 and Figure 6 As shown, in one embodiment, the support module 10 also includes a fourth support assembly 7 and a third drive assembly 8; the fourth support assembly 7 is connected to the first support assembly 1 and can move relative to the first support assembly 1 to generate displacement in the arrangement direction of the second support assembly 2 and the third support assembly 5; the first support assembly 1 is connected to the camera module 20 through the fourth support assembly 7; the third drive assembly 8 is connected to the first support assembly 1, and is used to drive the fourth support assembly 7 to move; the arrangement direction of the second support assembly 2 and the third support assembly 5 is defined as the second direction, the second direction is perpendicular to the first axis, and the second direction is perpendicular to the first direction. In the application scenario where the first direction and the first axis are parallel to the horizontal direction, the second direction is the vertical direction. Among them, the second direction is parallel to the Z axis.

[0093] In addition, after the detection device is assembled, the third driving assembly 8 drives the fourth supporting assembly 7 to move in a direction parallel to the optical axis direction of the camera module 20. When the camera module 20 rotates until the optical axis is parallel to the vertical direction, the third driving assembly 8 can drive the fourth supporting assembly 7 to move in the second direction (vertical direction). When the camera module 20 rotates until the optical axis is not parallel to the vertical direction, the third driving assembly 8 actually drives the fourth supporting assembly 7 to move in a direction that is an acute angle or an obtuse angle with the second direction. At this time, the fourth supporting assembly 7 has a displacement component in the second direction.

[0094] like Figure 3As shown, in one embodiment, the fourth support assembly 7 includes a fourth support plate 71, a fifth support plate 72 and a guide mechanism 73, the fourth support plate 71 is connected to the first support plate 11 through the guide mechanism 73, the fifth support plate 72 is connected to the fourth support plate 71, and the fourth support plate 71 is used to connect the camera module 20. Among them, the fourth support plate 71 is arranged in parallel with the first support plate 11, the fifth support plate 72 is arranged perpendicular to the fourth support plate 71, the surface of the fifth support plate 72 used to connect the camera module 20 is parallel to the first axis, and the fifth support plate 72 is located on the side of the fourth support plate 71 away from the first support plate 11, and the guide mechanism 73 is used to guide the movement of the fourth support plate 71. Among them, the movement of the fourth support plate 71 can drive the fifth support plate 72 and the camera module 20 connected to the fifth support plate 72 to move, thereby realizing that the fourth support assembly 7 drives the camera module 20 to move relative to the first support assembly 1, so that the fourth support assembly 7 and the camera module 20 are displaced in the second direction.

[0095] like Figure 6 As shown, in one embodiment, the third driving assembly 8 includes a motor 81 and a screw mechanism 82. The motor 81 drives the fourth support plate 71 to move through the screw mechanism 82 so as to cause the fourth support plate 71 to be displaced in the second direction.

[0096] It should also be understood that the support module 10 also includes a corresponding control module, which is used to control the operation of components such as the motor 81 in the support module 10. The control module can be a PLC, a single-chip microcomputer, and the like.

[0097] like Figure 2 As shown, in one embodiment, the camera module 20 includes a plurality of cameras 201, each of which is sequentially arranged on the first support assembly 1 along the first axis, and a portion of the field of view of two adjacent cameras 201 overlaps with each other. This can increase the shooting range of the entire camera module 20. At this time, each camera 201 has an optical axis, and the optical axes of the cameras 201 can be parallel to each other, and the optical axis of the camera module 20 is the optical axis of each camera 201.

[0098] like Figure 7 and Figure 8As shown, in one embodiment, the detection device 100 also includes a light source module 30 and a light source bearing module 40; the light source bearing module 40 is connected to the support module 10, and the light source module 30 is connected to the light source bearing module 40. The light source module 30 is used to project light to the object to be measured, and the light can be reflected by the object to be measured into the camera module 20 so that the camera module 20 can form an image. In addition, the light source module 30 can rotate relative to the light source bearing module 40 around a second axis to adjust the angle at which the light source module 30 projects light to the object to be measured; the second axis is parallel to the first axis. When the angle of the camera module 20 is adjusted, the angle of the light source module 30 can be adjusted accordingly so that the camera module 20 has a better shooting effect.

[0099] In actual use, the angle of the light source module 30 can be adjusted so that the light emitted by the light source module 30 is reflected by the object to be measured and propagates along the optical axis direction parallel to the camera module 20, so that the camera module 20 has a better imaging effect.

[0100] In addition, the light source bearing module 40 and the supporting module 10 can be respectively connected to corresponding supporting devices, in which case the light source bearing module 40 can be connected to the supporting module 10 through the supporting device; or, the light source bearing module 40 can also be directly connected to the supporting module 10, for example, the light source bearing module 40 can be connected to the bracket 52.

[0101] like Figure 7 and Figure 8 As shown, the light source bearing module 40 includes a first mounting plate 401 and a second mounting plate 402, the first mounting plate 401 and the second mounting plate 402 are spaced apart along a second axis, the light source module 30 is installed between the first mounting plate 401 and the second mounting plate 402, and the light source module 30 is rotatably connected to the first mounting plate 401 and the second mounting plate 402, respectively.

[0102] In addition, if Fig. 9As shown, the detection device 100 also includes an adjusting bolt 50, a locking threaded hole 301 is provided on the light source module 30, and an escape space 403 is provided on the second mounting plate 402. The escape space 403 is a through hole that penetrates the second mounting plate 402 along the second axis. The stud of the adjusting bolt 50 passes through the second mounting plate 402 from the escape space 403 and cooperates with the locking threaded hole 301. The depth of the adjusting bolt 50 screwed into the locking threaded hole 301 can be adjusted so that the bolt head of the adjusting bolt 50 can be in contact with the second mounting plate 402, thereby locking the light source module 30 and the second mounting plate 402 together, so that the light source module 30 is locked together with the light source bearing module 40. In addition, along the circumferential direction of the rotation of the light source module 30 around the second axis, there is a gap between the hole wall of the escape space 403 and the stud of the adjusting bolt 50, so that the adjusting bolt 50 can rotate a certain angle around the second axis together with the light source module 30. When the bolt head of the adjusting bolt 50 does not interfere with the second mounting plate 402 (i.e., the adjusting bolt 50 does not lock the second mounting plate 402 and the light source module 30), and the stud of the adjusting bolt 50 cooperates with the locking threaded hole 301, the light source module 30 can rotate around the second axis, and the adjusting bolt 50 will rotate accordingly.

[0103] In addition, the light source module 30 includes a light source and a supporting structure, the light source is connected to the supporting structure, both ends of the supporting structure are rotatably connected to the first mounting plate 401 and the second mounting plate 402, and the locking threaded hole 301 is arranged on the surface of the supporting structure close to the second mounting plate 402.

[0104] It should be understood that the above-mentioned related designs may also be replaced by other methods, such as:

[0105] In other embodiments, the first adjusting rod 31 may be driven to move along its own axial direction by electric or pneumatic means. In this case, the first driving component 3 also includes an electric cylinder or a pneumatic cylinder or other device that can drive the first adjusting rod 31 to move linearly.

[0106] In other embodiments, the second driving assembly 6 may also be a device such as an electric cylinder or a pneumatic cylinder that can drive the second supporting assembly 2 to move linearly.

[0107] In other embodiments, the third driving assembly 8 may also be a manual driving assembly, and its structural connection may be the same as that of the second driving assembly 6 .

[0108] In other embodiments, the first support plate 11 and the second support plate 21 may be rotatably connected together by other existing methods, for example, the two may be rotatably connected together by a hinge.

[0109] In other embodiments, at least one of the first assembly hole 1a and the second assembly hole 2a includes a plurality of sub-holes arranged at intervals along the same arc. The arrangement of the sub-holes along the arc may mean that the axes of the sub-holes are parallel to each other, and in the orthographic projection on a plane perpendicular to the axes of the sub-holes, the projections of the axes of the sub-holes are all located on the projection of the arc. In addition, the axis of the arc is the first axis.

[0110] When the first assembly hole 1a includes multiple sub-holes, the fastener 4 is inserted into the first assembly hole 1a, which means that the fastener 4 is inserted into one sub-hole; when the second assembly hole 2a includes multiple sub-holes, the fastener 4 is inserted into the second assembly hole 2a, which means that the fastener 4 is inserted into one sub-hole.

[0111] It should be understood that this embodiment is equivalent to replacing the arc-shaped hole of the above embodiment with a plurality of sub-holes arranged at intervals along the same arc line. Wherein, when the first assembly hole 1a includes a plurality of sub-holes arranged at intervals along the same arc line, the arc angle of the arc line is 10 degrees to 20 degrees, for example, the arc angle can be 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees or 20 degrees.

[0112] In addition, the plurality of sub-holes are arranged in two groups, one group of sub-holes are arranged in sequence along an arc, and the two groups of sub-holes are arranged in sequence along the radial direction of the midpoint of the arc.

[0113] When two groups of sub-holes are provided, the two groups of sub-holes are arranged at intervals along the radial direction of the midpoint of the arc, wherein the "radial direction of the midpoint of the arc" refers to the extension direction of the radius passing through the midpoint of the two arcs, and the radius is the radius of the arc. In addition, "the two groups of sub-holes are arranged at intervals along the radial direction of the midpoint of the arc" can also be understood as: the two arcs are arranged at intervals along the direction perpendicular to the first axis, and the two groups of sub-holes are symmetrical relative to the same plane. Among them, "the two groups of sub-holes are symmetrical relative to the same plane" means: when one group of sub-holes is divided into two mirror-symmetrical parts by the second plane, the other group of sub-holes is also divided into two mirror-symmetrical parts by the second plane.

[0114] In addition, when two groups of sub-holes are provided, the number of the assembly holes corresponding to one group of sub-holes can also be two. Among them, when the first assembly hole 1a is a group of sub-holes, the assembly hole corresponding to the group of sub-holes is the second assembly hole 2a, and when the second assembly hole 2a is a group of sub-holes, the assembly hole corresponding to the group of sub-holes is the first assembly hole 1a. In this case, there can also be two fasteners 4, and one fastener 4 cooperates with a group of sub-holes and the assembly hole corresponding to the group of sub-holes.

[0115] An embodiment of the utility model further provides an AVI appearance inspection machine, which includes the detection device 100 described in any one of the above embodiments.

[0116] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
