[0025] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0026] Please refer to Figure 1 and Figure 2 , the multi-station multi-angle image acquisition device 100 provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0027] The multi-station multi-angle image acquisition device 100 includes a box body 110, a bracket 120, a positioning mechanism 160, a first acquisition mechanism 130, a second acquisition mechanism 140, and a supplementary light mechanism 150; Among them, the bracket 120, the positioning mechanism 160, the first acquisition mechanism 130, and the supplementary lighting mechanism 150 are all arranged inside the box body 110. The positioning mechanism 160 is used to support the workpiece. The first acquisition mechanism 130 and the supplementary lighting mechanism 150 are both movably connected to the bracket 120 and are located above the positioning mechanism 160. The second acquisition mechanism 140 is arranged outside the box body 110. The box body 110 is provided with an acquisition port 111, and the acquisition port 111 is correspondingly arranged with the second acquisition mechanism 140.

[0028] During the acquisition operation, the box body 110 can isolate the ambient light source. The first acquisition mechanism 130 and the second acquisition mechanism 140 can perform image acquisition on the workpiece from different angles, and the supplementary lighting mechanism 150 is used to supplement light to the workpiece inside the box body 110 to ensure that the acquired images have sufficient brightness, thereby eliminating the negative impact of ambient light on the acquisition operation while achieving multi-angle acquisition.

[0029] In this embodiment, the box body 110 is a hollow cuboid structure. An access door is arranged on one side of the box body 110, and the access door can be rotated and opened to facilitate the maintenance or replacement of the components inside the box body 110, improving the convenience of maintenance.

[0030] In this embodiment, the bracket 120 includes a support 121 and a support rod 122 that are vertically connected. The support 121 is used to support the positioning mechanism 160 and is used to connect the second acquisition mechanism 140. The first acquisition mechanism 130 and the supplementary lighting mechanism 150 are used to be connected to the support rod 122. The relative positions of other mechanisms can be defined through the support 121 and the support rod 122.

[0031] Reference Figure 3 , the positioning mechanism 160 includes a positioning base 161, a rotating table 162, and a clamping block 163 that are connected in sequence. The rotating table 162 is used to drive the clamping block 163 to rotate relative to the positioning base 161. A second arc-shaped guide rail 1621 is formed at the top of the rotating table 162, and the arc-shaped inner side of the second arc-shaped guide rail 1621 faces the first acquisition mechanism 130. The clamping block 163 is slidably matched with the second arc-shaped guide rail 1621 and is used to clamp the workpiece.

[0032] Among them, the positioning base 161 is connected to the top surface of the support 121. The rotating table is used to rotate in the horizontal plane under the action of an external force. During the rotation, it can drive the clamping block 163 and the workpiece to rotate, thereby driving the workpiece to adjust the angle in the horizontal plane. Furthermore, by opening a second arc-shaped guide rail 1621 on the top of the rotating table, the arc-shaped opening of the second arc-shaped guide rail 1621 faces upward, and the clamping block 163 can drive the workpiece to move along the second arc-shaped guide rail 1621 for angle adjustment. For the positioning mechanism 160, through the relative rotation of the rotating table and the positioning base 161, and the arc-shaped sliding of the clamping block 163 and the second arc-shaped guide rail 1621, angle adjustment in two directions can be achieved. Specifically, the bottom end of the clamping block 163 is in an arc shape adapted to the second arc-shaped guide rail 1621.

[0033] It should be noted that in order to facilitate visual observation of the rotation angle of the rotating table 162 relative to the positioning base 161, a rotation angle scale can be provided on the positioning base 161. The clamping block 163 can also be provided with a clamping cavity for clamping the workpiece. A clamping handle is provided at one end of the clamping block 163, and the clamping block 163 can be driven to slide by rotating the clamping handle, so that the clamping cavity shrinks or expands. And the workpiece can be a complex geometric part.

[0034] Reference Figure 4 , the first acquisition mechanism 130 includes a first slider 131, a first connecting member 132, a first fixing plate 133, and a first camera 134 connected in sequence. The first slider 131 is slidably disposed on the bracket 120, the first fixing plate 133 is slidably disposed on the first connecting member 132, and the first camera 134 is disposed facing the positioning mechanism 160.

[0035] Specifically, the first slider 131 is slidably engaged with the support rod 122, and a first locking screw is provided on the side wall of the first slider 131 for abutting against the side wall of the support rod 122 for locking to prevent the first slider 131 from falling off the support rod 122.

[0036] During the acquisition operation, the position of the first camera 134 can be adjusted in two directions by the relative sliding of the first slider 131 and the support rod 122, and the relative sliding of the first fixing plate 133 and the first connecting member 132.

[0037] Reference Figure 4 and Figure 5, the first connecting member 132 includes a first arc-shaped guide rail 1321, a guide wheel set 1322 and a fixing block 1323. The inner arc of the first arc-shaped guide rail 1321 faces the positioning mechanism 160. The guide wheel set 1322 includes a first guide wheel 1326, a second guide wheel 1327 and a third guide wheel 1328. The first guide wheel 1326 cooperates with the outer side wall of the first arc-shaped guide rail 1321, and both the second guide wheel 1327 and the third guide wheel 1328 cooperate with the inner side wall of the first arc-shaped guide rail 1321. One end of the fixing block 1323 is connected to the first guide wheel 1326, the second guide wheel 1327 and the third guide wheel 1328 at the same time, and the other end of the fixing block 1323 is slidably matched with the first fixing plate 133.

[0038] In the working state, by applying force to the guide wheel set 1322, the guide wheel set 1322 can slide along the first arc-shaped guide rail 1321, so as to adjust the orientation angle of the first camera 134. The first guide wheel 1326, the second guide wheel 1327 and the third guide wheel 1328 are respectively arranged on both sides of the first arc-shaped guide rail 1321. One is to ensure the tight connection between the guide wheel set 1322 and the first arc-shaped guide rail 1321 and prevent them from easily separating; the other is to ensure the relative position stability of the three guide wheels and prevent the three guide wheels from skewing relative to the first arc-shaped guide rail 1321, thereby driving the first camera 134 to deflect accidentally.

[0039] It should be noted that because the arc opening of the first arc-shaped guide rail 1321 faces downward, when the guide wheel set 1322 is located on both sides of the first arc-shaped guide rail 1321, affected by gravity, there is a safety hazard that the guide wheel set 1322 moves towards the lower part of the first arc-shaped guide rail 1321. The first guide wheel 1326 can be an eccentric wheel, and the peripheral wall of the first guide wheel 1326 is formed with friction teeth 1329. When the relative position of the guide wheel set 1322 relative to the first arc-shaped guide rail 1321 is fixed, the eccentric far end surface of the first guide wheel 1326 can be made to contact the first arc-shaped guide rail 1321, and with the friction between the friction teeth 1329 and the first arc-shaped guide rail 1321, the first guide wheel 1326 can be prevented from continuing to rotate relative to the first arc-shaped guide rail 1321, so as to achieve the self-locking effect of the guide wheel set 1322 and avoid its continued rotational movement towards the lower part of the first arc-shaped guide rail 1321 under the influence of gravity.

[0040] Therefore, through the arc-shaped sliding cooperation between the first arc-shaped guide rail 1321 and the guide wheel set 1322, the first camera 134 can be driven to deflect, so that the first camera 134 can adjust its angle relative to the workpiece.

[0041] Reference Figure 6, the second acquisition mechanism 140 includes a telescopic slide rail 141, a support block 142, an adjustment frame 143, a second fixing plate 144, and a second camera 145 that are connected in sequence. One end of the telescopic slide rail 141 is connected to the support 120, the support block 142 is connected to the other end of the telescopic slide rail 141, the adjustment frame 143 is used to drive the second fixing plate 144 to approach or move away from the support block 142 under the action of an external force, and the second camera 145 is arranged facing the positioning mechanism 160.

[0042] In this embodiment, the telescopic slide rail 141 is a three-stage slide rail structure, and the width of the three-stage slide rail gradually increases from the inside to the outside. Through the telescopic cooperation of the three-stage slide rail, the telescopic slider can have a sufficiently large movement stroke to drive the second camera 145 to approach or move away from the workpiece, realizing the position adjustment of the second camera 145.

[0043] Reference Figure 7 , the adjustment frame 143 includes an adjustment base 1431, a rotating shaft 1432, a rotating handle 1433, two lower sliders 1434, an X-shaped rotating link 1435, two upper sliders 1436, and a guide shaft 1437. The adjustment base 1431 is connected to the support block 142, the rotating handle 1433 is eccentrically connected to the rotating shaft 1432, the rotating shaft 1432 is formed with a first spiral section 1438 and a second spiral section 1439 with opposite rotation directions, the two lower sliders 1434 are respectively in spiral cooperation with the first spiral section 1438 and the second spiral section 1439, the two bottom ends of the X-shaped rotating link 1435 are respectively connected to the two lower sliders 1434, the two top ends of the X-shaped rotating link 1435 are respectively connected to the two upper sliders 1436, the two upper sliders 1436 are sleeved on the guide shaft 1437, and the guide shaft 1437 is connected to the second fixing plate 144; The rotating handle 1433 is used to rotate under the action of an external force and drive the rotating shaft 1432 to rotate, so that the two lower sliders 1434 approach or move away from each other and drive the X-shaped rotating link 1435 to deform, so that the guide shaft 1437 relatively moves away from or approaches the adjustment base 1431.

[0044] In this embodiment, the X-shaped rotating link 1435 includes two single links that are rotatably connected, and the rotatable connection parts of the two are both at the central positions to ensure that the top or bottom ends of the two links can remain flush during the rotatable connection process.

[0045] In addition, in order to prevent the two bottom ends of the X-shaped rotating link 1435 from approaching and contacting each other and causing excessive extrusion, a limiting block can be arranged at the central position of the rotating shaft 1432. The limiting block is located between the first spiral section 1438 and the second spiral section 1439 and is used to limit the two bottom ends of the X-shaped rotating link 1435 to ensure the safe distance between the two bottom ends.

[0046] During the adjustment process, the adjustment base 1431 plays a supporting role. The operator can manually drive the rotation handle 1433 to rotate, so as to drive the synchronous rotation of the rotating shaft 1432. By providing a first helical section 1438 and a second helical section 1439 with opposite helix directions on the rotating shaft 1432, the two lower sliders 1434 can be made to approach or move away from each other, so that the X-shaped rotating link 1435 contracts or expands. When the two lower sliders 1434 approach each other, the X-shaped rotating link 1435 contracts, and its two top ends approach and rise, so as to drive the guide shaft 1437 away from the rotating shaft 1432, raising the positions of the second fixed plate 144 and the second camera 145. When the two lower sliders 1434 move away from each other, the X-shaped rotating link 1435 expands, and its two top ends also move away and lower, so as to drive the guide shaft 1437 closer to the rotating shaft 1432, lowering the positions of the second fixed plate 144 and the second camera 145.

[0047] It should be noted that through the cooperation of the rotating shaft 1432, the lower slider 1434 and the X-shaped rotating link 1435, the rotational movement in the height direction can be first converted into an axial movement in the horizontal direction, and then into a movement in the height direction. Thus, on the premise of facilitating the application of force, the position adjustment of the second camera 145 is achieved. Moreover, through the connection and cooperation of the two lower sliders 1434, the X-shaped rotating link 1435 and the two upper sliders 1436, the stability during the movement conversion process is ensured, and the X-shaped rotating link 1435 is prevented from easily deflecting towards one side during the deformation process.

[0048] Reference Figure 6 , in order to further improve the comprehensiveness of the angle adjustment of the second camera 145, the second acquisition mechanism 140 may further include a rotating disk 146. One end of the rotating disk 146 is rotatably connected to the second fixed plate 144, and the second camera 145 is connected to the other end of the rotating disk 146.

[0049] Specifically, the disk surface of the rotating disk 146 is perpendicular to the top surface of the support 121. Therefore, the rotation of the rotating disk 146 can drive the second camera 145 to perform angle adjustment in the vertical direction. In addition, the second fixed plate 144 is L-shaped, and the rotating disk 146 is connected to the top end of the second fixed plate 144 and has a certain interval from the bottom plate surface of the second fixed plate 144, thus preventing the second fixed plate 144 from interfering with the rotation of the second camera 145.

[0050] Reference Figure 8, The supplementary lighting mechanism 150 includes a second slider 151, an extension rod 152, a second connecting member 153, and a light source 154 connected in sequence. The second slider 151 is slidably disposed on the support 120. The extension rod 152 is slidably connected to the second slider 151. The light source 154 is annular, and the annular cavity of the light source 154 is correspondingly disposed with the positioning mechanism 160 and the first acquisition mechanism 130.

[0051] During the acquisition operation, the second slider 151 can slide relative to the support rod 122 to drive the light source 154 for height adjustment; the extension rod 152 can slide relative to the second slider 151 to drive the light source 154 for horizontal position adjustment, and the extension rod 152 is perpendicular and staggered with the vertical rod. In addition, the light source 154 is annular. When the first camera 134 acquires an image, the acquired optical signal can pass through the annular cavity. On the one hand, it makes the light source 154 and the optical signal as likely to correspond and concentrate as possible, ensuring that the acquisition object has sufficient brightness; on the other hand, it excludes the influence of external light on the acquisition operation as much as possible, ensuring the accuracy of image acquisition.

[0052] Specifically, the second connecting member 153 includes an adapter plate 1531 and two extension plates 1532. The adapter plate 1531 is rotatably connected to one end of the extension rod 152. The adapter plate 1531 is provided with two spaced-apart first long holes 1536. The two extension plates 1532 are respectively movably connected to the two first long holes 1536. The long extension direction of the first long hole 1536 is perpendicular to the extension direction of the extension rod 152. The two extension plates 1532 are respectively provided with second long holes 1537. The long extension direction of the second long hole 1537 is parallel to the extension direction of the extension rod 152. The light source 154 is simultaneously movably connected to the two second long holes 1537.

[0053] When it is necessary to drive the light source 154 for position adjustment, on the one hand, the adapter plate 1531 can be rotated relative to the end of the extension rod 152, and the deflection angle of the light source 154 can be adjusted by rotation; on the other hand, the connection position between the extension plate 1532 and the first long hole 1536 can be adjusted to make the light source 154 perform position adjustment along the long extension direction of the first long hole 1536; on the third hand, the connection position between the light source 154 and the second long hole 1537 can be adjusted. In addition, when it is necessary to use a light source 154 with different outer diameters or inner diameters, the extension plate 1532 can be moved to achieve the installation and adjustment of different light sources 154.

[0054] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims described above.
