[0051] Please refer to Figures 1 to 5 The embodiment provides a printed matter detection device for detecting printed matter. The printed matter detection device comprises a frame body 1, a fixed platform 2, a movement mechanism 3, a scanning mechanism 4 and a processing mechanism 5. The fixed platform 2 is arranged on the frame body 1 and is configured to carry and fix the printed matter. The movement mechanism 3 is arranged on the frame body 1 and comprises a carrying part 31 capable of sliding in a predetermined direction, and the carrying part 31 is located above the fixed platform 2. The scanning mechanism 4 is arranged on the carrying part 31 and is configured to collect a printed image of the printed matter on the fixed platform 2. The processing mechanism 5 is arranged on the frame body 1 and is electrically connected with the scanning mechanism 4. The processing mechanism 5 is used for detecting whether the printed image collected by the scanning mechanism 4 has defects.
[0052] When detecting, first, the printed matter is placed on the fixed platform 2, and the printed matter is fixed by the fixed platform 2, then the moving mechanism 3 starts to work to drive the scanning mechanism 4 to move through the bearing part 31, at the same time, the scanning mechanism 4 gradually collects the printed image of the printed matter, and feeds the collected printed image to the processing mechanism 5, then the processing mechanism 5 compares the collected printed image with the standard image to analyze whether the printed matter has defects, and feeds back the detection result, and finally the printed matter on the fixed platform 2 is taken off.
[0053] In this way, the scanning mechanism 4 and the processing mechanism 5 cooperate to detect whether the printed matter has defects, which has high automation degree, small labor intensity of the workers, and high detection efficiency. In addition, compared with the manual detection method, the detection result deviation caused by the negligence of the operator can be avoided, thereby helping to improve the accuracy of the detection result.
[0054] It should be noted that the printed matter in the present application mainly refers to a carrier for carrying printed content in a large format, including but not limited to a large sheet of paper, a film, a cloth or other materials capable of displaying printed graphic information. Those skilled in the art can understand that the present application is not limited to the detection of paper printing materials, as long as the material can be scanned and analyzed by the above-mentioned detection device for its printing quality, it can be regarded as the "printed matter" described in the present application.
[0055] If the printed matter of large size is detected, the size of the fixed platform 2 will be relatively large, thereby causing the volume of the printed matter detection device to be large, the floor area to be large, and a large space in the production workshop to be occupied. Therefore, in order to reduce the floor area of the printed matter detection device, the fixed platform 2 is inclined. In addition, the inclined fixed platform 2 enables the workers to take and place the printed matter from the lower side of the fixed platform 2, which is more convenient to operate.
[0056] In the embodiment, the frame body 1 includes a frame made of profiled material by welding, and the outer periphery of the frame is covered with a plurality of sheet metal parts to form a box body. In addition, the bottom of the frame is also provided with components such as casters and foot cups, which are not described in detail. It should be noted that the preset direction mentioned in the foregoing is the length direction of the frame body 1.
[0057] In order to improve the stability of the moving mechanism 3 driving the scanning mechanism 4, the moving mechanism 3 includes at least two bearing parts 31, all the bearing parts 31 are distributed on both sides of the fixed platform 2, and the two sides of the scanning mechanism 4 are arranged on the bearing parts 31 on both sides. The moving mechanism 3 further includes a driving part 32 arranged on the frame body 1, and the driving part 32 is drivingly connected with all the bearing parts 31 through a synchronous assembly 33 to synchronously drive all the bearing parts 31 to slide.
[0058] It can be understood that the driving connection between the movement mechanism 3 and the scanning mechanism 4 is more reliable by supporting and fixing the scanning mechanism 4 through the plurality of bearing parts 31 distributed on both sides of the fixed platform 2. It can also be understood that the movement of the scanning mechanism 4 is more stable by synchronously driving all the bearing parts 31 to slide through the driving member 32 and the synchronous assembly 33.
[0059] In particular, the movement mechanism 3 further comprises at least two synchronous belt modules 34 arranged on the frame body 1, the number of the synchronous belt modules 34 corresponds to the number of the bearing parts 31, and the plurality of bearing parts 31 are arranged one by one on the movement end of the plurality of synchronous belt modules 34. It can be understood that the synchronous belt module 34 has the advantages of accurate transmission, high efficiency, and being suitable for long-distance transmission, thereby further improving the stability of the movement of the scanning mechanism 4. It should be noted that the specific model of the synchronous belt module 34 is selected according to the actual application scene, and therefore is not limited.
[0060] In the embodiment, the synchronous assembly 33 comprises a plurality of transmission shafts connected through a shaft coupling, and the plurality of synchronous belt modules 34 are in transmission connection with the corresponding transmission shafts. In addition, in the embodiment, the driving member 32 is composed of a servo motor, a speed reducer and the like, and drives any transmission shaft in transmission connection, which will not be described in detail.
[0061] Preferably, the movement mechanism 3 further comprises a leveling assembly 35 arranged between the synchronous belt module 34 and the frame body 1, the leveling assembly 35 is used for adjusting the position and angle of the synchronous belt module 34 relative to the frame body 1, and the number of the leveling assembly 35 corresponds to the number of the synchronous belt module 34. In this way, the position and angle of the movement mechanism 3 can be adjusted to meet the use requirements of the scanning mechanism 4. It should be noted that the adjusting assembly is preferably an existing adjusting bolt, and the synchronous belt module 34 is installed on the frame body 1 through a plurality of adjusting bolts. In addition, the number and distribution position of the adjusting bolts are selected according to the actual application scene, and the angle of the synchronous belt module 34 can be adjusted by adjusting the height difference of each position through a plurality of adjusting bolts, and therefore will not be described in detail.
[0062] In the embodiment, the fixed platform 2 comprises an adsorption panel 21 and a vacuum generator. The adsorption panel 21 is arranged on the frame body 1 and is used for bearing the printed matter, the adsorption panel 21 comprises a plurality of partitions, and a plurality of ventilation holes are distributed on each partition. The vacuum generator is arranged on the frame body 1 and is in communication with the plurality of ventilation holes through a pipeline assembly, so that all the ventilation holes can generate a vacuum adsorption force. In this way, the printed matter can be fixed by the vacuum adsorption method, which is convenient to operate and does not easily cause damage to the printed matter.
[0063] It should be noted that the adsorption panel 21 is preferably a black aluminum plate and is subjected to hard anodizing treatment, so that it has high hardness, excellent wear resistance and corrosion resistance, color stability, good appearance and scientific and technological sense. It should be noted that the structure and working principle of the vacuum generator are prior art and will not be described in detail. More importantly, the black adsorption panel 21 has high contrast with the printed matter, and the printed image collected by the scanning mechanism 4 is easy to be stably cut by the processing mechanism 5, and will not be overloaded or missed. In addition, when detecting a double-sided printed matter of a thin paper of about 40 grams, the false positive probability caused by backside printing can be reduced, and the imaging and detection stability can be improved.
[0064] It should be noted that in order to ensure the integrity of the image collected by the scanning mechanism 4, the initial position of the bearing part 31 needs to be away from the nearest side of the fixed platform 2 by a certain distance. The time corresponding to this distance cannot be shorter than the starting time of the scanning mechanism 4. Similarly, the time corresponding to this distance cannot be shorter than the starting time of the fixed platform 2, so that after the printed matter is placed on the fixed platform 2, the staff starts the machine, and when the scanning mechanism 4 moves to the nearest side of the fixed platform 2, the scanning mechanism 4 is in the scanning state, and at the same time, the fixed platform 2 fixes the printed matter.
[0065] Further, the pipeline assembly includes an input pipe, a flow divider 22, and an output pipe 23. One end of the input pipe is in communication with the outlet of the vacuum generator, and the other end is in communication with the inlet of the flow divider 22. The flow divider 22 includes a plurality of flow outlets, and the number of flow outlets corresponds to the number of partitions. The number of output pipes 23 corresponds to the number of partitions, and one end of each of the plurality of output pipes 23 corresponds to one of the plurality of flow outlets, and the other end of each of the plurality of output pipes 23 corresponds to one of the plurality of partition interfaces of the adsorption panel 21.
[0066] In this way, the suction force provided by the vacuum generator can be evenly distributed to the plurality of partitions of the adsorption panel 21 through the flow divider 22, thereby improving the uniformity of the suction force of the adsorption panel 21, and further better fixing the printed matter. In this embodiment, the adsorption panel 21 has four partitions, each of which is provided with two interfaces in communication with the flow outlets. Correspondingly, the flow divider 22 includes an inlet and eight flow outlets, and the eight flow outlets are uniformly arranged along the circumference. The output pipe 23 is provided with eight output pipes. In this way, the inlet position of the flow divider 22 is located at the center of the circumferences of the eight flow outlets, which can ensure that the suction force is evenly distributed to the eight flow outlets, thereby ensuring that the suction force of the eight partitions on the adsorption panel 21 is equivalent. It should be noted that the flow outlets and the output pipes 23 are preferably connected in a pagoda head connection mode, which is simple in structure and reliable in connection. It should be noted that the input pipe and the outlet of the vacuum generator are locked by a stainless steel clamp, which is reliable in connection and easy to operate.
[0067] To place the printed matter more accurately on the adsorption panel 21, the side edges of the adsorption panel 21 are provided with positioning blocks 24, and the positioning blocks 24 are provided with scale marks 241. In this way, by abutting the side edges of the printed matter against the positioning blocks 24, the printed matter can be made more orderly, with high consistency, and it is more convenient for the scanning mechanism 4 to collect images. In addition, the scale marks 241 make it easier to adjust the accurate position of the printed matter. In the embodiment, two positioning blocks 24 are provided, and the two positioning blocks 24 are arranged on the two adjacent side edges of the adsorption panel 21, respectively.
[0068] Specifically, the scanning mechanism 4 includes a mounting member 41, a scanning camera 42, and a light-emitting member 43. The mounting member 41 is arranged on the bearing part 31. The scanning camera 42 is arranged on the mounting member 41, and the scanning camera 42 is used to collect the printed image of the printed matter. The light-emitting member 43 is arranged on the mounting member 41, and the light-emitting member 43 is used to illuminate the printed matter, so as to ensure the quality of the printed image collected by the scanning camera 42. In the embodiment, the box is provided with movement grooves in a predetermined direction, and the mounting member 41 extends to the upper side of the box through the movement grooves. The number of the mounting member 41 and the number of the movement grooves correspond to the number of the bearing part 31. It should be noted that, in order to prevent sundries from falling into the box through the movement grooves, dustproof brushes are arranged on both sides of the movement grooves along the length direction of the movement grooves.
[0069] In the embodiment, the bearing part 31, the mounting member 41, and the movement grooves are all provided with two. It should be noted that the scanning camera 42 and the light-emitting member 43 are preferably a linear scanning camera in one piece. The specific model of the linear scanning camera is not specifically required. It should be further noted that the scanning mechanism 4 is electrically connected with the processing mechanism 5 as mentioned above. The processing mechanism 5 is specifically a controller, a computer, or other structure having the function of processing and analyzing images, and thus will not be described in detail. In addition, in order to improve the convenience of adjusting the position and angle of the linear scanning camera, the linear scanning camera is installed on the mounting member 41 through the structure composed of the plurality of adjusting bolts as mentioned above, and will not be described in detail.
[0070] In order to prevent the scanning mechanism 4 in motion from colliding with the staff or other articles, the printed matter detection platform further includes a safety light barrier 6 arranged on the frame 1. The safety light barrier 6 is electrically connected with the processing mechanism 5, and the safety light barrier 6 is configured to form a sensing area on the frame 1 when the movement mechanism 3 is working. The sensing area is arranged corresponding to the maximum movement area of the movement mechanism 3. The processing mechanism 5 can control the movement mechanism 3 to stop working when there is sundry in the sensing area.
[0071] It should be noted that the safety light barrier 6 is composed of a transmitter and a receiver. A protective net is formed by an infrared light beam. When an object enters the area, which is the sensing area in the embodiment, the infrared light will be blocked, and the receiver will detect the change and trigger the safety protection measures.
