[0039] Currently, UV flatbed printing generally doesn't use visual positioning. However, as customer needs evolve, selective use of visual positioning has emerged to meet the needs of printing products with high precision or extremely irregular shapes. However, some existing visual positioning devices in the UV printing field are generally only able to achieve vertical position adjustment, that is, to adjust the height of the inspection camera in the vertical direction, thereby changing the accuracy of visual inspection. With the continuous development of the market and the changes in customer needs, existing one-way adjustment visual inspection UV printing equipment can no longer meet customer needs. Based on these needs, this embodiment proposes a multi-directional adjustment mechanism 20.

[0040] See also Figures 1 to 14The embodiment discloses a multi-directional adjusting mechanism 20, which comprises a support plate 22, an adjusting plate 25 connected to the support plate 22, a connecting plate 24 connected to the adjusting plate 25, and a rotating plate 26 connected to the connecting plate 24; wherein the support plate 22 and the adjusting plate 25 are connected by an adjusting assembly, so that the adjusting plate 25 can be adjusted to rotate in a vertical plane with a first rotating shaft perpendicular to the vertical plane, and the rotating plate 26 can be adjusted to rotate with a second rotating shaft perpendicular to the first rotating shaft, and the rotating plate 26 is used for connecting an adjusted unit, which is an industrial detection camera 200 in the embodiment, and can also be any module that needs to be adjusted in multiple directions in other embodiments.

[0041] The multi-directional adjusting mechanism 20 of the embodiment connects the adjusted industrial detection camera (i.e. a CCD camera) 200 to the rotating plate 26, the rotating plate 26 can be adjusted to rotate relative to the connecting plate 24, so as to adjust the image shooting direction of the industrial detection camera 200, and the connecting plate 24 is movably connected to the support plate 22 through the adjusting plate 25, and the support plate 22 and the adjusting plate 25 are connected by an adjusting assembly to adjust the rotation in the vertical plane, so as to change the perpendicularity between the industrial detection camera 200 and the shooting object, and improve the shooting accuracy. That is, the multi-directional adjusting mechanism 20 of the embodiment can adjust the rotation of the industrial detection camera 200 in the vertical direction and the front-back swing, and has higher flexibility compared with the existing single-directional adjusting mechanism, and can be adjusted in multiple directions according to actual needs.

[0042] The support plate 22 is vertically arranged, the adjusting plate 25 is arranged in parallel with the support plate 22, that is, the adjusting plate 25 is adjusted to rotate with a first rotating shaft perpendicular to the axis of the support plate 22, as shown in Figure 6 , the adjusting plate 25 is adjusted to swing forward and backward in the vertical direction.

[0043] The rotating plate 26 is arranged in parallel with the connecting plate 24, that is, the rotating plate 26 is adjusted to rotate with a second rotating shaft perpendicular to the axis of the connecting plate 24. It should be noted that the vertical plane in the embodiment is a relative position, and is not limited to the vertical direction to the ground plane in the actual space, so the first rotating shaft perpendicular to the vertical plane and the second rotating shaft perpendicular to the first rotating shaft are both relative directions, which are used to indicate that the multi-directional adjusting mechanism 20 has the adjusting function in two different directions.

[0044] The adjusting assembly comprises a rotating shaft 224 connected to the support plate 22 and a fixing unit 223, the rotating shaft 224 is arranged in the center of the adjusting plate 25, the adjusting plate 25 can rotate around the rotating shaft 224, and the fixing unit 223 is used for locking the adjusting plate 25 after the adjusting plate 25 is rotated to a set angle.

[0045] Specifically, the adjustment plate 25 is a semicircular plate or a fan-shaped plate, and the rotation shaft 224 is disposed on a vertical midline of the adjustment plate 25 passing through the center of the circle, so that the adjustment plate 25 can swing about the rotation shaft 224 .

[0046] It should be noted that the rotating shaft 224 may also pass through the rear end portion of the supporting plate 22 and be connected to the adjusting plate 25 . In this case, the relative rotation mode between the adjusting plate 25 and the supporting plate 22 remains unchanged.

[0047] Please refer again Figure 10 The fixing unit 223 includes: an adjusting block 2231 and an adjusting screw 2232 screwed to the adjusting block 2231. The adjusting block 2231 is fixedly connected to the support plate 22. The adjusting screw 2232 is passed through the adjusting block 2231, and the end thereof can extend out of the adjusting block 2231 and abut against the connecting plate 24 or the adjusting plate 25 in the rotation direction of the adjusting plate 25.

[0048] Specifically, the fixing units 223 are provided with two groups, and the two groups of fixing units 223 are arranged in the front and rear extension width directions of the support plate 22. When the adjustment plate 25 is adjusted to a suitable angle, the screws 2232 of the fixing units 223 are adjusted respectively so that the lengths of the ends thereof extending out are different, thereby fixing the adjustment plate 25 in the adjusted position and keeping it unchanged.

[0049] Please refer again Figure 6 and Figure 8 At least two adjustment holes 2612 (2621) are provided on the rotating plate 26 along the same circumference, and a horizontal adjustment screw (not shown in the figure) is passed through the adjustment hole 2612 (2621), and the end of the horizontal adjustment screw is screwed to the connecting plate 24.

[0050] Specifically, the adjustment holes 2612 (2621) are circular arc holes extending along the same circumference. When adjusting the rotating plate 26, the horizontal adjustment screw is first loosened, and then the rotating plate 26 is rotated. When the rotating plate 26 is rotated to the desired position, the horizontal adjustment screw is tightened, thereby fixing the rotating plate 26 to the connecting plate 24. Correspondingly, the industrial inspection camera 200 being adjusted is also fixed to the support plate 24.

[0051] like Figure 8As shown, the rotating plate 26 includes: a first rotating disk 261 and a second rotating disk 262. The middle parts of the first rotating disk 261 and the second rotating disk 262 jointly enclose an assembly hole 260. The first rotating disk 261 and the second rotating disk 262 are each provided with a corresponding assembly step structure 2611 at the joint. The first rotating disk 261 and the second rotating disk 262 are fixedly connected at the assembly step 2611 by screws 2613. In other words, the joints of the first rotating disk 261 and the second rotating disk 262 are each provided with a step structure in opposite directions, thereby facilitating the rapid alignment and assembly of the two. When connecting the industrial inspection camera 200, first open the first rotating disk 261 and the second rotating disk 262, and then respectively embrace the gooseneck of the industrial inspection camera 200 to connect the industrial inspection camera 200 to the rotating plate 26.

[0052] Please refer again Figure 11 In this embodiment, the connecting plate 24 is perpendicularly connected to the support plate 22. The connecting plate 24 is also perpendicular to the adjustment plate 25. A positioning slot 241 is recessed on the upper surface of the connecting plate 24. The rotating plate 26 is positioned within the positioning slot 241. A through-hole 242 is provided at the bottom of the positioning slot 241. The connecting plate 24 is also provided with a clearance hole 243 that communicates with the through-hole 242 and extends to the side edge of the connecting plate 24. Since the industrial inspection camera 200 is connected to the rotating plate 26, the lens must pass through the rotating plate 26 and the connecting plate 24. To facilitate assembly, interconnected clearance holes 243 and through-holes 242 are provided. During assembly, the gooseneck of the industrial inspection camera 200 passes through the clearance hole 243 and fits into the through-hole 242.

[0053] The adjusting plate 25 is provided with a screw hole 252 connected to the rotating shaft 2232 and a screw hole 251 connected to the fixing screw 222. When the adjusting plate 25 is rotated to a suitable angle, it is locked by the fixing screw 222 passing through the adjusting hole 221.

[0054] Please refer again Figure 6 and Figure 12 The support plate 22 is further connected to the lifting plate 21. The support plate 22 is provided with at least one longitudinally extending slot 225. A guide member (not shown), such as a screw, is inserted into the slot 225. One end of the guide member is connected to the lifting plate 21. The lifting plate 21 and the support plate 22 are movably connected by a lifting adjustment assembly 23, so that the support plate 22 can be raised and lowered vertically relative to the lifting plate 21. When the support plate 22 is adjusted to a desired height relative to the lifting plate 21, the guide member and the lifting adjustment assembly 23 jointly secure the two in position.

[0055] Among them, the lifting adjustment component 23 includes: an adjustment seat 231 and an adjustment bolt 232 screwed on the adjustment seat 231, the adjustment seat 231 is fixedly connected to the bottom of the lifting plate 21, and the end of the adjustment bolt 232 extends out of the adjustment seat 231 and abuts against the support plate 22 in the lifting direction of the support plate 22, that is, the adjustment bolt 232 abuts against the bottom of the support plate 22 in the vertical direction.

[0056] The lifting and adjusting components 23 are provided with two groups and are arranged in the width direction of the lifting plate 21. The support plate 22 can be raised and lowered relative to the lifting plate 21 under the guidance of the guide member. When the support plate 22 is raised and lowered to the required height, the adjusting bolts 232 of the lifting and adjusting components 23 are adjusted at the same time so that they abut against the bottom of the support plate 22, so that the support plate 22 remains at the set height position.

[0057] In order to improve the supporting strength of the lifting plate 21 , a reinforcing rib 211 is provided on the back thereof. Similarly, a reinforcing rib is also provided on the bottom of the connecting plate 24 .

[0058] Please refer again Figures 1 to 5 This embodiment further provides a visual inspection device 100, which includes the multi-directional adjustment mechanism 20 described above. The multi-directional adjustment mechanism 20 is used to adjust the industrial inspection camera 200 in multiple directions. The adjustment directions include vertical lifting adjustment, vertical rotation adjustment, and front-to-back rotation angle adjustment relative to the support plate 22.

[0059] Industrial inspection camera 200 includes a camera body 201, a mounting plate 203 connected to the gooseneck of camera body 201, and a heat sink 202 for dissipating heat from camera body 201. Heat sink 202 is assembled to multi-directional adjustment mechanism 20 via a connecting arm 14. An auxiliary light source 13 is located below the lens of camera body 201, and a cover 12 is located outside the lens to prevent UV light from penetrating and endangering the user.

[0060] This embodiment also provides a UV printing device, which includes the visual inspection device 100 as described above. Specifically, it is connected to the head of the UV printer through an assembly plate 11 connected to the lifting plate 21, so as to follow the head to obtain image information of the printing format.

[0061] The multi-directional adjustment mechanism of this embodiment, through its support plate, adjustment plate, connecting plate, rotating plate, and corresponding movable adjustment components, enables multi-directional adjustment of the adjusted unit. Its overall structure is simple and adjustment is convenient.
