Description

Technical Field

[0001] The present application relates to the technical field of digital watermarks, and in particular to a digital watermark anti-counterfeiting device. Background Art

[0002] Digital watermarking embeds specific digital signals into digital products to protect their copyright, integrity, copy protection, or tracking. By embedding digital watermarks using information hiding, they prove the creator's ownership of their work and can serve as evidence in identifying and prosecuting illegal infringements. Using industrial cameras to capture digital images of printed materials ensures high image quality and capture speed. Digital watermark detection software running on a computer can quickly and accurately detect watermarks. Compared to traditional anti-counterfeiting technologies, digital watermarking offers advantages such as rapid detection, high security, and low cost. Therefore, applying digital watermarking technology to printed product anti-counterfeiting holds great promise.

[0003] In the application detection of digital watermarks, the anti-counterfeiting device usually includes a scanning device and a conveyor belt. The conveyor belt passes the article through the scanning device, and the scanning device scans the digital watermark on the article. When the digital watermark is located on the bottom surface of the article, the scanning device cannot scan the digital watermark and needs to be manually flipped and straightened, which increases the workload of the staff and is prone to missed detections. The effectiveness of the anti-counterfeiting device cannot be fully utilized, so it needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a digital watermark anti-counterfeiting device to solve the problem that existing anti-counterfeiting devices cannot fully exert their effectiveness.

[0005] The digital watermark anti-counterfeiting device provided in this application adopts the following technical solution:

[0006] A digital watermark anti-counterfeiting device includes a scanning device and a conveyor belt. The conveyor belt is provided with a flipping mechanism for rotation, and the flipping mechanism is provided with a clamping mechanism for clamping an article. The scanning device is provided with a driving member. A linkage structure is provided between the driving member and the flipping mechanism. The driving member drives the flipping mechanism to rotate through the linkage structure.

[0007] By adopting the above technical solution, the clamping mechanism clamps the article, and the conveyor belt drives the flipping mechanism to move along the length direction of the conveyor belt. When the article passes through the scanning device, the scanning device first scans the top and side surfaces of the article. During the continued transmission, the driving member drives the flipping mechanism to flip through the linkage structure. The flipping mechanism flips and drives the article to flip at the same time, so that the bottom surface of the article that was originally facing downward is flipped upward, which facilitates the scanning device to continue scanning the original bottom surface of the article. Through this automatic flipping structure, the workload of the staff is effectively reduced, and the effectiveness of the anti-counterfeiting device can be fully exerted.

[0008] Optionally, the conveyor belt is provided with a support frame, the flipping mechanism includes two sliding plates arranged on the support frame, a rotating shaft rotatably arranged on the sliding plates, and a rotating seat fixedly arranged on the rotating shaft, the clamping mechanism is fixedly arranged on the rotating seat, and the rotating shaft cooperates with the linkage structure.

[0009] By adopting the above technical solution, the two clamping mechanisms clamp the article, the driving member drives the rotating shaft to rotate through the linkage structure, the rotating shaft drives the rotating seat to rotate, and drives the corresponding clamping mechanism to rotate to realize the flipping of the article.

[0010] Optionally, the clamping mechanism includes a clamping member provided on the rotating seat and a contact plate provided on the clamping member, the clamping member is used to drive the contact plate to slide, and an anti-slip pad is provided on one side of the contact plate.

[0011] By adopting the above technical solution, the two pressing members simultaneously drive the two contact plates to slide toward or away from each other, and the anti-slip pad contacts the object, which can improve the stability of the contact between the contact plate and the object.

[0012] Optionally, the linkage structure includes a linkage shaft, a driving gear, a linkage gear, and a transmission member. The linkage shaft is rotatably arranged on the support frame, one end of the linkage shaft is fixedly connected to the driving gear, and the other end is fixedly connected to the linkage gear. The driving gear cooperates with the driving member, the linkage gear cooperates with the transmission member and drives the rotating shaft to rotate, and the driving member drives the driving gear to rotate.

[0013] By adopting the above technical solution, the driving member drives the active gear to rotate, the active gear drives the linkage shaft to rotate, the linkage shaft drives the linkage gear to rotate, the linkage gear cooperates with the transmission member and drives the rotating shaft to rotate, thereby realizing the flipping of the object.

[0014] Optionally, the sliding plate is slidably arranged on the support frame, and the transmission member includes a transmission gear fixedly arranged on the rotating shaft, a transmission tooth bar fixedly arranged on the support frame, and a linkage tooth bar fixedly arranged on the sliding plate, the transmission gear is meshed with the transmission tooth bar, and the linkage tooth bar is meshed with the linkage gear.

[0015] By adopting the above technical solution, the linkage gear rotates to drive the linkage rack bar to slide, and then drives the sliding plate to slide, so that the transmission gear engages with the transmission rack bar to drive the transmission gear to rotate to realize the flipping of the object. At the same time, the sliding of the sliding plate can realize the lifting and lowering of the object, and realize the flipping of the object while lifting, reducing the situation of flipping jamming due to the large size of the object.

[0016] Optionally, the driving member is a driving plate provided on the scanning device, the driving plate is provided with a connecting groove for the driving gear to slide, and a side wall of the connecting groove is provided with a driving toothed bar meshing with the driving gear.

[0017] By adopting the above technical solution, when the conveyor belt drives the flipping mechanism to move, when the active toothed bar enters the connecting groove and slides along the length direction of the connecting groove, the active toothed bar can drive the active gear to rotate when it is engaged with the active toothed bar, and the active gear drives the linkage shaft to rotate, which has a linkage effect and can realize the automatic flipping of the flipping mechanism at the same time, without the need to provide an additional driving source for the flipping.

[0018] Optionally, a first reset member is provided between the sliding plate and the support frame, and the first reset member is used to drive the sliding plate to reset after sliding.

[0019] By adopting the above technical solution, when the driving gear is separated from the active toothed bar, the sliding plate resets and slides under the action of gravity. During the reset and sliding process, the transmission gear engages with the transmission toothed bar, and the reset rotation of the transmission gear drives the reset rotation of the rotating shaft, driving the object to reset and flip. At the same time, the first reset member can also drive the sliding plate to reset and slide. The first reset member can buffer the sliding of the sliding plate, thereby improving the stability of the reset and sliding of the sliding plate.

[0020] When the driving gear meshes with the active toothed bar, the sliding plate slides, the first reset member is elastically deformed by force, and maintains the elastic reset trend. When the driving gear is separated from the active toothed bar, the first reset member can drive the sliding plate to slide.

[0021] Optionally, a second reset member is provided between the linkage shaft and the support frame, and the second reset member is used to drive the linkage shaft to reset after rotation.

[0022] By adopting the above technical solution, when the driving gear is engaged with the active toothed bar, the linkage shaft rotates, the second reset member is subjected to force to produce elastic deformation, and maintains the trend of elastic reset. When the driving gear is separated from the active toothed bar, and the sliding plate is reset under the action of the first reset member, the second reset member also drives the sliding plate to reset and slide, thereby accelerating the efficiency of the sliding plate reset.

[0023] Optionally, the support frame is provided with a guide groove, and the sliding plate is provided with a guide bar that cooperates with the guide groove.

[0024] By adopting the above technical solution, the sliding connection between the guide bar and the guide groove guides and limits the sliding of the sliding plate, thereby improving the sliding stability of the sliding plate and preventing the sliding plate from rotating under the transmission of the linkage gear and the linkage toothed bar.

[0025] Optionally, the scanning device includes a body located above the conveyor belt, a scanner disposed on the body, and a controller disposed on the body and connected to the scanner.

[0026] By adopting the above technical solution, the digital watermark on the object is scanned by a scanner, and the scanned data is transmitted to the controller. The controller analyzes and calculates the scanned data, performs anti-counterfeiting identification on the digital watermark, and makes a judgment to facilitate identification by staff.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The clamping mechanism clamps the article, and the conveyor belt drives the flipping mechanism to move along the length of the conveyor belt. When the article passes through the scanning device, the scanning device first scans the top and side surfaces of the article. During the continued transmission, the driving member drives the flipping mechanism to flip through the linkage structure. The flipping mechanism flips and drives the article to flip at the same time, so that the bottom surface of the article, which was originally facing downward, turns upward, making it easier for the scanning device to continue scanning the original bottom surface of the article. This automatic flipping structure effectively reduces the workload of the staff and can give full play to the effectiveness of the anti-counterfeiting device.

[0029] 2. The linkage gear rotates to drive the linkage toothed bar to slide, which in turn drives the sliding plate to slide, so that the transmission gear engages with the transmission toothed bar to drive the transmission gear to rotate to flip the item. At the same time, the sliding of the sliding plate can realize the lifting and lowering of the item, so that the item can be flipped while being lifted, reducing the possibility of flipping and jamming due to the large size of the item.

[0030] 3. When the conveyor belt drives the turning mechanism to move, the active toothed bar enters the connecting groove and slides along the length direction of the connecting groove. When the active toothed bar engages with the active toothed bar, it can drive the active toothed bar to rotate, which has a linkage effect and can realize the automatic turning of the turning mechanism at the same time without providing an additional driving source for the turning.

[0047] The implementation principle of a digital watermark anti-counterfeiting device in the embodiment of the present application is as follows:

[0048] The clamping mechanism 4 clamps the article, and the conveyor belt 2 drives the flipping mechanism 3 to move along the length direction of the conveyor belt 2. When the article passes through the scanning device 1, the scanning device 1 first scans the top and side surfaces of the article. During the continued transmission, the driving member 5 drives the flipping mechanism 3 to flip through the linkage structure 6. When the flipping mechanism 3 flips, it also drives the article to flip, so that the bottom surface of the article that was originally facing downward is flipped upward, which facilitates the scanning device 1 to continue scanning the original bottom surface of the article. Through this automatic flipping structure, the work intensity of the staff is effectively reduced, and the effectiveness of the anti-counterfeiting device can be fully exerted.

[0049] The linkage gear 63 rotates to drive the linkage rack bar 643 to slide, and then drives the sliding plate 31 to slide, so that the transmission gear 641 engages with the transmission rack bar 642 to drive the transmission gear 641 to rotate to realize the flipping of the object. At the same time, the sliding of the sliding plate 31 can realize the lifting and lowering of the object, and realize the flipping of the object while lifting, reducing the situation of flipping jamming due to the large size of the object.

[0050] When the conveyor belt 2 drives the flipping mechanism 3 to move, the active rack bar 53 enters the connecting groove 52 and slides along the length direction of the connecting groove 52. When the active rack bar 53 is engaged with the active rack bar 53, it can drive the active rack bar 53 to rotate, which has a linkage effect. At the same time, it can realize the automatic flipping of the flipping mechanism 3 without providing an additional driving source for the flipping.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
