Description

Technical Field

[0001] The present invention relates to optical detection technology for new materials, in particular to optical detection equipment for new printed materials. Background Art

[0002] It is well known that after printing, printed products made of new materials need to use optical detection instruments to perform optical detection on the transmittance, development, etc. of the new materials. During the detection process, different detection light sources are generally selected according to different materials, such as light sources of different colors for detection, and one material may require light sources of multiple colors for switching detection. Therefore, multiple light sources need to be used in the detection process. When optically detecting printed products made of new materials, the printed products are fixed on the surface of the detector through the existing fixed clamping mechanism, and the different light sources set in the visual detection head are used to detect the printed products.

[0003] The shortcomings of existing technologies are that switching between light sources typically requires manual replacement of light source components or the use of complex mechanical structures, which is cumbersome and inefficient. Furthermore, traditional devices lack an automatic reset mechanism, preventing unused light sources from returning to their original positions, potentially leading to structural confusion or accidental triggering. The positioning accuracy of the light source and the detection port is insufficient, which can affect the accuracy of detection results. The reset structure is poorly compatible with the light source's flipping trajectory, which can cause motion freezes or incomplete resets, making it difficult to meet the requirements of efficient and accurate detection.

[0046] In another embodiment provided by the present invention, the limiting slide rail 10 is provided in an arc shape to match the moving trajectory of the inner slide bar 18 during the flipping process of the cross bar 9.

[0047] In another embodiment provided by the present invention, the reset track 16 is provided in a straight line.

[0048] After printing, printed materials made of new materials need to be optically inspected for transmittance, development, and other conditions using an optical detector. During the inspection process, different light sources are generally selected based on different materials, such as light sources of different colors. One material may require multiple colors of light sources for switching inspection, so multiple light sources are required during the inspection process.

[0049] When performing optical inspection on printed products of new materials, the printed products are fixed on the surface of the detector 1 through the existing fixed clamping mechanism, and then the printed products are inspected using different light sources provided in the visual inspection head 2;

[0050] When the light source head 6 needs to be switched during the detection process, the rotating drum 3 is rotated, and the rotating drum 3 rotates to mesh the rack 8 and the gear 7 provided on the inner wall. When the rotating drum 3 rotates counterclockwise, the multiple groups of gears 7 are respectively meshed with the rack 8. The gear 7 meshed with the rack 8 drives the cross bar 9 fixedly connected to the gear 7 away from the light source head 6 installed at one end of the gear 7 to flip upward to the position of the light source port 4 opened at the center of the fixed disk 5, so that the light source head 6 corresponds to the position of the light source port 4, so that the light source emitted by the light source head 6 is irradiated to the surface of the detector 1 through the light source port 4, thereby performing optical detection on the printed matter of the new material;

[0051] During this process, the meshing between gear 7 and rack 8 requires the following explanations:

[0052] 1. When the detector 1 is not in use, the light source heads 6 connected to the multiple sets of cross bars 9 are folded around the inside of the rotating drum 3 so that the light source heads 6 do not shine outward from the light source opening 4, and the rack 8 and the multiple sets of gears 7 are in a separated state.

[0053] Second, when the drum 3 is rotated, multiple sets of gears 7 are meshed with the racks 8 respectively. When the gears 7 are meshed with the racks 8, as the drum 3 rotates counterclockwise, the gears 7 will rotate counterclockwise on the surface of the racks 8 along with the racks 8. Since the gears 7 are fixedly connected to the bottom end of the cross bar 9, the gears 7 cannot rotate on their own. Therefore, when the gears 7 rotate and mesh with the racks 8, the racks 8 will drive the cross bar 9 to flip downward under the rotation of the torsion spring bearing 12 through the gears 7, thereby forming a lever with the torsion spring bearing 12 as the fulcrum, and flipping the light source head 6 fixedly connected to the top of the cross bar 9 from the inner and outer peripheries of the drum 3 to the light source port 4 opened at the center of the fixed disk 5.

[0054] 3. When the drum 3 is rotated to flip the crossbar 9, the slide bar 18 provided in the middle of the side of the crossbar 9 that is in contact with the fixed plate 5 will slide along the limit rail 10 in an arc as the crossbar 9 flips.

[0055] Fourth, when the light source head 6 is flipped to the position facing the light source port 4, the gear 7 reaches the position close to the edge of the end of the rack 8. At this time, the gear 7 can continue to slide toward the end of the rack 8 for meshing, and the cross bar 9 is attached to the middle part of one side of the fixed plate 5 through the movable groove 20 and the return spring 19. The slide bar 18 reaches the initial position in the slot 15. At this time, the slide bar 18 is inserted into the initial position in the slot 15, that is, the position where the slot 15 connects to the end of the limiting slide rail 10. Since the depth of the slot 15 is deeper than the depth of the end of the limiting slide rail 10, the slide bar 18 will be clamped at the initial section of the slot 15, thereby fixing the use position of the light source head 6;

[0056] 5. When the light source head 6 needs to be replaced, continue to rotate the drum 3, turn the light source head 6 upward for a certain distance, and completely slide the gear 7 to the end position of the rack 8 and separate it from the gear 7. During this process, the slide bar 18 will slide from the initial position of the slot 15 to the end position and connect with the initial position of the reset track 16. Since the depth of the initial position of the reset track 16 is deeper than the depth of the end position of the slot 15, the slide bar 18 will automatically fall from the end of the slot 15 to the reset track 16. When the drum 3 is continued to be rotated, due to the separation between the gear 7 and the rack 8, the cross bar 9 is connected to the fixed plate 5. The torsion spring bearing 12 rotates automatically, and drives the cross bar 9 to reset and retract and fold at the inner and outer circumferences of the rotating drum 3. In this process, the slide bar 18 on the inner side of the cross bar 9 slides along the reset track 16 from the initial position at the end of the connecting groove 15 to the initial position of the connecting limit slide rail 10. Since the depth of the limit slide rail 10 is deeper than the reset track 16 at the connection between the reset track 16 and the limit slide rail 10, when the slide bar 18 slides to this point, it automatically slides into the limit slide rail 10, so that when the cross bar 9 rotates next time, the slide bar 18 automatically slides along the arc trajectory of the limit slide rail 10 upwards.

[0057] 6. Since the limiting slide rail 10 on which the slide bar 18 slides during the upward flipping process is arc-shaped, it is adapted to the movable trajectory of the slide bar 18 when flipping upward. Therefore, when the cross bar 9 flips upward, the position of the slide bar 18 in the movable groove 20 remains unchanged and the return spring 19 is not squeezed. When the cross bar 9 is reset downward, the slide bar 18 slides downward along the straight return track 16. At this time, the slide bar 18 will slide in the movable groove 20 and stretch the return spring 19. When the slide bar 18 slides to the initial position of the limiting slide rail 10, the stretching spring provides a pulling force to the slide bar 18, and the slide bar 18 slides to the inside of the initial position of the limiting slide rail 10.

[0058] It should be noted that:

[0059] The bottom end of the slide bar 18 is connected to a slide plate 21 via a spring rod 22. The slide plate 21 is slidably connected to the movable groove 20, and the other end of the slide bar 18 is slidably connected to the limiting slide rail 10, the slot 15 and the reset track 16. That is, the connection between the slide plate 21 and the slide bar 18 has a certain rigidity, and it can also ensure that the slide bar 18 can change its position as the depth between the limiting slide rail 10, the slot 15 and the reset track 16 changes.

[0060] A torsion spring shaft is provided inside the torsion spring bearing 12. The initial position is that the cross bar 9 folds the light source head 6 on the inner and outer circumferences of the rotating drum 3. When the gear 7 and the rack 8 slide and the cross bar 9 is rotated, the internal torsion spring shaft is rotated. Therefore, after the gear 7 and the rack 8 are separated, the torsion spring bearing 12 automatically rotates to drive the cross bar 9 to drive the light source head 6 to fold on the inner and outer circumferences of the rotating drum 3.

[0061] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
