Description

Technical Field

[0001] This utility model relates to the field of image printing quality inspection technology, specifically an image printing quality inspection device. Background Technology

[0002] After the image is printed on the printing plate, it needs to be inspected by quality inspection equipment. Generally, this is done through a camera recognition and detection module. The processing equipment compares the captured photo with the predetermined image to find the image that does not meet the quality standard, and marks the position and coordinates of the image so that it can be found and removed in subsequent processing.

[0003] The existing inspection device includes a winding module, an unwinding module, and an inspection module. The unwinding module releases the wound printing paper, and the printing paper passes through the inspection module for printing quality inspection. The inspected portion is then wound up by the winding module. The existing inspection device can only inspect the image on one side of the printing paper. If the printing paper has images printed on both sides, the paper roll needs to be reinstalled and its installation direction changed when inspecting the image on the other side, which is not convenient to use. Utility Model Content

Support rollers are respectively provided at both ends of the top plate and at both ends of the upper surface of the base plate. A transfer roller is also provided on the base plate, and the transfer roller is located therein. Above a support roller, a cover is installed on the operating platform. Inside the cover, two sets of detection modules are installed. A material passage groove is opened on one side of the cover. A baffle is rotatably connected to the cover.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-4As shown, an image printing quality inspection device includes an operating table 1, a mounting frame 2 on the operating table 1, a ball screw 3 on the mounting frame 2, a first motor 4 for driving the ball screw 3 on the mounting frame 2, a slider 5 threadedly connected to the ball screw 3, a base plate 6 slidably connected to the mounting frame 2, the base plate 6 being fixedly connected to the slider 5, a top plate 7 above the base plate 6, and a support plate 8 connecting the base plate 6 and the top plate 7. Support rollers 9 are respectively provided at both ends of the top plate 7 and at both ends of the upper surface of the base plate 6. A transfer roller 10 is also provided on the base plate 6, located directly above one of the support rollers 9. A cover 11 is provided on the operating table 1. The cover 11 has two sets of detection modules 12 inside. A material passage 13 is opened on one side of the cover 11. A baffle 14 is rotatably connected to the cover 11. A placement plate 15 is provided on one side of the operating table 1. A slide table 16 is slidably connected to the placement plate 15. The slide table 16 is connected to the base plate 6 through a vertical plate 17. Two upright plates 18 are provided on the slide table 16. A sleeve 19 is rotatably connected to the upright plate 18. A positioning plate 20 is provided on the outer surface of the sleeve 19. A retaining ring 21 is threadedly connected to the sleeve 19. A second motor 22 is provided on the side of the upright plate 18 closest to the operating table 1. The output end of the second motor 22 is connected to the sleeve 19 on the upright plate 18.

[0019] When installing the printing substrate, first flip the baffle 14 to open one side of the cover 11. Then, start the first motor 4, which drives the ball screw 3 to rotate. Through the threaded connection with the slider 5, the bottom plate 6 moves along the mounting frame 2. At the same time, the top plate 7, connected by the support plate 8, moves with the bottom plate 6. The slide table 16, connected by the vertical plate 17, also moves with the bottom plate 6. When the bottom plate 6 and the top plate 7 are removed from the cover 11, the first motor 4 stops. Then, the material cylinder 26 containing the printing substrate is installed on the sleeve 19 away from the operating table 1. By rotating the retaining ring 21 on the sleeve 19, the material cylinder 26 is fixed on the sleeve 19. Finally, the empty optical cylinder 27 is installed on another sleeve 19. Next, by rotating the retaining ring 21 on the sleeve 19, the optical cylinder 27 is fixed on the sleeve 19. Then, the substrate on the material cylinder 26 is pulled out. First, one end of the substrate is pulled into the housing 11 from the material passage 13 on the housing 11, and the substrate passes over the top plate 7. At this time, the substrate will contact the support rollers 9 at both ends of the top plate 7, but the substrate will not directly contact the top plate 7. Then, the substrate is pulled to pass under the two support rollers 9 on the bottom plate 6. At this time, the substrate is above the bottom plate 6 but does not directly contact the bottom plate 6. The substrate only contacts the two support rollers 9 on the bottom plate 6. Then, one end of the substrate is pulled around the transfer roller 10 and fixed on the optical cylinder 27, thus completing the installation of the substrate.

[0020] After the substrate is installed, the first motor 4 is started, which controls the base plate 6 and top plate 7 to move into the housing 11. At the same time, the slide table 16 and the material cylinder 26 and light cylinder 27 on the slide table 16 move. When the base plate 6 and top plate 7 are completely inside the housing 11, the baffle 14 is flipped to keep the inside of the housing 11 relatively closed. Since the substrate inside the housing 11 is guided, the two detection modules 12 inside the housing 11 can simultaneously detect the images on both sides of the substrate on the base plate 6 and top plate 7. Furthermore, the top plate 7 can prevent interference between the two detection modules 12, thus ensuring the accuracy and stability of the image printing quality detection.

[0021] When controlling the movement of the printing substrate, it is only necessary to start the second motor 22. The second motor 22 drives the sleeve 19 to rotate, and drives the optical cylinder 27 on the sleeve 19 to rotate. When the optical cylinder 27 rotates, it can rewind the printing substrate that has been inspected. At the same time, the material cylinder 26 on the other sleeve 19 can continuously release the printing substrate under the traction of the optical cylinder 27 until all the printing substrate on the material cylinder 26 is released, and then the second motor 22 stops working.

[0022] There is a certain friction between the sleeve 19 on which the material cylinder 26 is installed and the upright plate 18. When the light cylinder 27 stops rotating, the material cylinder 26 can also stop relatively quickly under the action of the friction between the sleeve 19 and the upright plate 18. At the same time, when the light cylinder 27 pulls the material cylinder 26 to release the printing material, the release speed of the printing material on the material cylinder 26 is also relatively slow, thereby avoiding the large inertia of the material cylinder 26 and the poor stability of unwinding. Alternatively, a third motor can be set on one side of the upright plate 18 to control the rotation of the sleeve 19 on which the material cylinder 26 is installed, so as to ensure the efficient and stable release of the printing material by the material cylinder 26.

[0023] The detection module 12 includes modules such as an illumination module, a camera module, a processing module, and a storage module. It is used to detect and record the locations where the image quality is substandard, so as to facilitate subsequent removal. Since image quality detection is an existing technology, its specific working principle and process will not be described in detail here.

[0024] Furthermore, two fixing plates 23 are provided on the placement plate 15. A rotating shaft 24 is rotatably connected to the fixing plate 23. One end of the rotating shaft 24 can extend into the inside of the sleeve 19. When the rotating shaft 24 extends into the sleeve 19, it can support one end of the sleeve 19, thereby improving the stability of the material cylinder 26 during unwinding and the light cylinder 27 during winding.

[0025] Furthermore, the end of the rotating shaft 24 near the vertical plate 18 is chamfered to facilitate the insertion of the rotating shaft 24 into the sleeve 19.

[0026] Furthermore, the outer surface of the cover 11 is provided with a slope, and the baffle 14 can lean against the cover 11 after being flipped over.

[0027] Furthermore, a handle 25 is provided on the outer surface of the baffle 14.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
