[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1 and Figure 2The multi-station and multi-angle image acquisition device 100 provided in the embodiment of the present invention can solve the above problems, which will be described in detail below.

[0039] The multi-station multi-angle image acquisition device 100 includes a housing 110, a bracket 120, a positioning mechanism 160, a first acquisition mechanism 130, a second acquisition mechanism 140, and a fill light mechanism 150;

[0040] Among them, the bracket 120, the positioning mechanism 160, the first collection mechanism 130 and the fill light mechanism 150 are all arranged on the inner side of the box 110. The positioning mechanism 160 is used to support the workpiece. The first collection mechanism 130 and the fill light mechanism 150 are both movably connected to the bracket 120 and are located on the upper side of the positioning mechanism 160. The second collection mechanism 140 is arranged on the outside of the box 110. The box 110 is provided with a collection port 111, and the collection port 111 is arranged corresponding to the second collection mechanism 140.

[0041] During the acquisition process, the box 110 can be used to isolate the ambient light source, and the first acquisition mechanism 130 and the second acquisition mechanism 140 can acquire images of the workpiece from different angles. The fill light mechanism 150 is used to fill light the workpiece in the box 110 to ensure that the acquired image has sufficient brightness, thereby eliminating the negative impact of ambient light on the acquisition operation while achieving multi-angle acquisition.

[0042] In this embodiment, the box body 110 is a hollow rectangular parallelepiped structure. An inspection door is provided on one side of the box body 110. The inspection door can be rotated open to facilitate maintenance or replacement of components in the box body 110, thereby improving the convenience of inspection.

[0043] In this embodiment, the bracket 120 includes a vertically connected support 121 and a support rod 122. The support 121 is used to support the positioning mechanism 160 and to connect the second collection mechanism 140. The first collection mechanism 130 and the fill light mechanism 150 are used to be connected to the support rod 122. The relative positions of other mechanisms can be limited by the support 121 and the support rod 122.

[0044] refer to Figure 3 The positioning mechanism 160 includes a positioning base 161, a rotating platform 162 and a clamping block 163 connected in sequence. The rotating platform 162 is used to drive the clamping block 163 to rotate relative to the positioning base 161. A second arc guide rail 1621 is formed at the top of the rotating platform 162. The inner side of the arc of the second arc guide rail 1621 is set toward the first collection mechanism 130. The clamping block 163 slides with the second arc guide rail 1621 and is used to clamp the workpiece.

[0045] Among them, the positioning base 161 is connected to the top surface of the support 121, and the rotating table is used to rotate in the horizontal plane under the action of external force. While rotating, 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 providing a second arc guide rail 1621 on the top of the rotating table, so that the arc opening of the second arc guide rail 1621 faces the upper side, the clamping block 163 can drive the workpiece to move along the second arc guide rail 1621 to adjust the angle. As for the positioning mechanism 160, the angle adjustment in two directions can be achieved through the relative rotation of the rotating table and the positioning base 161, and the arc sliding of the clamping block 163 and the second arc guide rail 1621. Specifically, the bottom end of the clamping block 163 is in an arc shape that is compatible with the second arc guide rail 1621.

[0046] It is worth noting that to facilitate visual observation of the rotation angle of the rotating table 162 relative to the positioning base 161, a rotation angle ruler can be provided on the positioning base 161. The clamping block 163 can also have a clamping cavity for clamping the workpiece. A clamping handle is provided at one end of the clamping block 163. By rotating the clamping handle, the clamping block 163 can be driven to slide, thereby shrinking or expanding the clamping cavity. Furthermore, the workpiece can be a part with complex geometry.

[0047] refer to 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 set on the bracket 120, the first fixing plate 133 is slidably set on the first connecting member 132, and the first camera 134 is set toward the positioning mechanism 160.

[0048] 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 pressing against the side wall of the support rod 122 for locking to prevent the first slider 131 from falling on the support rod 122 .

[0049] During the acquisition process, 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 .

[0050] refer to Figure 4 and Figure 5The first connecting member 132 includes a first arcuate guide rail 1321, a guide wheel group 1322 and a fixed block 1323. The arc inner side of the first arcuate guide rail 1321 is set toward the positioning mechanism 160. The guide wheel group 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 wall of the first arcuate guide rail 1321, and the second guide wheel 1327 and the third guide wheel 1328 both cooperate with the inner wall of the first arcuate guide rail 1321. One end of the fixed 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 fixed block 1323 slides with the first fixed plate 133.

[0051] In operation, force can be applied to the guide wheel assembly 1322 to cause it to slide along the first curved guide rail 1321, thereby adjusting 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 disposed on either side of the first curved guide rail 1321. These functions ensure a tight connection between the guide wheel assembly 1322 and the first curved guide rail 1321, preventing them from easily becoming detached. Furthermore, these functions ensure a stable relative position of the three guide wheels, preventing them from tilting relative to the first curved guide rail 1321 and potentially causing the first camera 134 to tilt unexpectedly.

[0052] It is worth noting that because the arc-shaped opening of the first curved guide rail 1321 is facing downward, when the guide wheel group 1322 is located at both sides of the first curved guide rail 1321, there is a safety hazard that the guide wheel group 1322 moves toward the lower part of the first curved guide rail 1321 due to the influence of gravity. The first guide wheel 1326 can be an eccentric wheel, and the peripheral wall of the first guide wheel 1326 can be formed with friction teeth 1329. When the relative position of the guide wheel group 1322 relative to the first curved guide rail 1321 is fixed, the eccentric distal end surface of the first guide wheel 1326 can be in contact with the first curved guide rail 1321, and with the help of the friction force between the friction teeth 1329 and the first curved guide rail 1321, the first guide wheel 1326 can be prevented from continuing to rotate relative to the first curved guide rail 1321, so as to achieve a self-locking effect on the guide wheel group 1322, and prevent it from continuing to rotate and move toward the lower part of the first curved guide rail 1321 under the influence of the action.

[0053] Therefore, through the arc-shaped sliding cooperation between the first arc-shaped guide rail 1321 and the guide wheel group 1322, the first camera 134 can be driven to deflect, thereby allowing the first camera 134 to adjust its angle relative to the workpiece.

[0054] refer to Figure 6The second acquisition mechanism 140 includes a telescopic slide rail 141, a support block 142, an adjustment frame 143, a second fixed plate 144 and a second camera 145 connected in sequence. One end of the telescopic slide rail 141 is connected to the bracket 120, and 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 fixed plate 144 close to or away from the support block 142 under the action of external force. The second camera 145 is set toward the positioning mechanism 160.

[0055] In this embodiment, the telescopic slide rail 141 is a three-level slide rail structure, and the width of the three-level slide rail gradually increases from the inside to the outside. Through the telescopic cooperation of the three-level slide rail, the telescopic slider can have a sufficiently large movable stroke to drive the second camera 145 closer to or away from the workpiece, thereby realizing the position adjustment of the second camera 145.

[0056] refer to Figure 7 The adjusting frame 143 includes an adjusting 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 adjusting base 1431 is connected to the supporting block 142. The rotating handle 1433 is eccentrically connected to the rotating shaft 1432. A first spiral segment 1438 and a second spiral segment 1439 with opposite rotation directions are formed on the rotating shaft 1432. The two lower sliders 1434 are spirally engaged with the first spiral segment 1438 and the second spiral segment 1439 respectively. The two bottom ends of the X-shaped rotating link 1435 are respectively connected to the two lower sliders 1434, and 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 fixed plate 144.

[0057] The rotating handle 1433 is used to rotate under the action of external force and drive the rotating shaft 1432 to rotate, so that the two lower sliders 1434 move closer to or away from each other and drive the X-shaped rotating link 1435 to deform, so that the guide shaft 1437 moves relatively away from or close to the adjustment base 1431.

[0058] In this embodiment, the X-shaped rotating link 1435 includes two single links that are rotatably connected, and the rotating connection parts of the two links are both at the center position to ensure that the top ends or bottom ends of the two links can remain flush during the rotation connection process.

[0059] In addition, in order to avoid excessive extrusion when the two bottom ends of the X-shaped rotating link 1435 approach each other and contact each other, a limit block can be set at the center position of the rotating shaft 1432. The limit block is located between the first spiral segment 1438 and the second spiral segment 1439, and is used to limit the two bottom ends of the X-shaped rotating link 1435 to ensure a safe distance between the two bottom ends.

[0060] During the adjustment process, the adjustment base 1431 serves as a support, allowing the operator to manually rotate the rotating handle 1433, thereby driving the synchronous rotation of the rotating shaft 1432. By providing a first helical section 1438 and a second helical section 1439 with opposite rotation directions on the rotating shaft 1432, the two lower sliders 1434 can be moved toward or away from each other, thereby causing the X-shaped rotating link 1435 to contract or expand. When the two lower sliders 1434 move toward each other, the X-shaped rotating link 1435 contracts, its two top ends approaching each other and rising, driving the guide shaft 1437 away from the rotating shaft 1432, thereby raising the position 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, its two top ends also moving away from each other and lowering, driving the guide shaft 1437 toward the rotating shaft 1432, thereby lowering the position of the second fixed plate 144 and the second camera 145.

[0061] It should be noted that, through the coordination of the rotational axis 1432, the lower slider 1434, and the X-shaped rotating link 1435, rotational motion in the height direction can be first converted into axial motion in the horizontal direction, and then into movement in the height direction, thereby enabling the position adjustment of the second camera 145 while conveniently applying force. Furthermore, the coordination of the two lower sliders 1434, the X-shaped rotating link 1435, and the two upper sliders 1436 ensures stability during the motion conversion process, preventing the X-shaped rotating link 1435 from easily deflecting toward one side during deformation.

[0062] refer to Figure 6 In order to further improve the comprehensiveness of the angle adjustment of the second camera 145, the second acquisition mechanism 140 can also 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.

[0063] Specifically, the surface of the rotating disk 146 is perpendicular to the top surface of the support 121, so the rotation of the rotating disk 146 can drive the second camera 145 to adjust its angle in the vertical direction. In addition, the second fixing plate 144 is L-shaped, and the rotating disk 146 is connected to the top end of the second fixing plate 144 and is separated from the bottom end of the second fixing plate 144 by a certain distance, thereby preventing the second fixing plate 144 from interfering with the rotation of the second camera 145.

[0064] refer to Figure 8The fill light 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 set on the bracket 120, and 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 corresponding to the positioning mechanism 160 and the first collection mechanism 130.

[0065] During image acquisition, the second slider 151 can slide relative to the support rod 122 to adjust the height of the light source 154. The extension rod 152 can also slide relative to the second slider 151 to adjust the horizontal position of the light source 154. The extension rod 152 and the vertical rod are arranged perpendicularly and staggered. Furthermore, the light source 154 is annular, and when the first camera 134 captures an image, its collected light signal can pass through the annular cavity. This not only ensures that the light source 154 and the light signal are aligned and concentrated, ensuring sufficient brightness for the captured object, but also minimizes the impact of external lighting on the acquisition process, ensuring accurate image acquisition.

[0066] 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 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 also movably connected to the two second long holes 1537.

[0067] When the position of the light source 154 needs to be adjusted, the adapter plate 1531 can be rotated relative to the end of the extension rod 152 to adjust the deflection angle of the light source 154. Secondly, the connection position between the extension plate 1532 and the first elongated hole 1536 can be adjusted to adjust the position of the light source 154 along the elongated direction of the first elongated hole 1536. Thirdly, the connection position between the light source 154 and the second elongated hole 1537 can be adjusted. In addition, when light sources 154 with different outer or inner diameters are required, the extension plate 1532 can be moved to achieve installation and adjustment of different light sources 154.

[0068] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
