Description

Technical Field

[0001] This utility model relates to the field of viewing table technology, and in particular to an electronic viewing table for printed materials. Background Technology

[0002] To facilitate effective control over the printing quality of printed materials, it is necessary to observe the color of the printed materials during the proofing process. The printed materials are placed on a stencil and compared with the sample. The finished color of the stencil is observed under standard light source and compared with the sample color, thereby completing the inspection of the printing quality. It can also be used for quality sampling and tracking of pre-press, in-press, and post-press products to avoid color deviations in the printed materials and help control the printing quality. However, some thinner printed materials are prone to wrinkling when placed on the stencil, which prevents the printed materials from being completely flattened. This can cause deviations when the stencil is used for sampling, thus affecting the inspection results of the stencil. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where thin printed materials are prone to wrinkling when placed on a viewing table, resulting in the printed materials not being fully flattened and deviations occurring during sampling, thus affecting the testing results of the viewing table. This invention provides an electronic viewing table for printed materials.

[0004] The purpose of this utility model is achieved through the following technical solution: an electronic viewing platform for printed materials, including a frame, a negative pressure placement platform installed on the frame, a background wall corresponding to the negative pressure placement platform installed on the frame, a lifting plate installed on the upper part of the background wall, a projector and a camera corresponding to the negative pressure placement platform installed at the bottom of the lifting plate, a display screen installed on the background wall, a control center installed on one side of the frame, the control center being electrically connected to the projector and the camera respectively, a touch screen installed on the control center, and the touch screen being electrically connected to the display screen. The projector is configured to project an electronic image of the product sample onto the negative pressure placement platform for comparison with the actual product, and the camera is configured to take pictures of the actual product and send them to the control center for automatic comparison with the electronic manuscript of the sample, and send the comparison results to the touch screen and the display screen for display, so as to facilitate the observation of the staff;

[0005] The bottom surface of the negative pressure placement platform is equipped with a negative pressure chamber. The negative pressure placement platform is provided with multiple sets of ventilation holes that communicate with the negative pressure chamber. A negative pressure fan is installed at the air outlet of the negative pressure chamber, and the air outlet of the negative pressure fan extends to the back of the frame. By setting up the negative pressure chamber and the negative pressure fan in combination, the actual product on the negative pressure placement platform can be suctioned and flattened to avoid wrinkles, ensure the accuracy of camera image capture, and improve the accuracy of product detection and comparison by the control center.

[0006] A further technical solution is to install lighting on the bottom surface of the lifting platform, which corresponds to the negative pressure placement platform. The lighting is a strip light source and is electrically connected to the control center. After the lighting is uniformly processed, it illuminates the products on the negative pressure placement platform, so that the color reproduction of the camera is better when it captures the image.

[0007] A further technical solution is that the negative pressure placement stage is made of magnetic stainless steel, and a magnetic pressure block is installed on the negative pressure placement stage. By setting the negative pressure placement stage to be made of magnetic stainless steel and cooperating with the magnetic pressure block, the product placed on the negative pressure placement stage can be pressed and fixed, ensuring the stability of the product placed on the negative pressure placement stage and ensuring the accuracy of subsequent image acquisition.

[0008] A further technical solution is to install an electric slide on the background wall. The moving end of the electric slide is connected to one side of the lifting plate. The electric slide can drive the lifting plate to rise and fall along the background wall. The electric slide can drive the lifting plate to rise and fall, which can adapt to products of different sizes for image capture and avoid the camera blurring when the product size is too small, thus avoiding the impact on the comparison results.

[0009] A further technical solution is to use an area scan camera. Setting the camera to an area scan camera can capture high-precision images with higher resolution and faster sensitivity, capturing more details and more accurate colors, thus improving the accuracy of subsequent comparisons.

[0010] A further technical solution is to install a sample storage drawer on the rack, which is slidably connected to the rack. By setting up the sample storage drawer, some physical samples can be stored for manual comparison.

[0011] A further technical solution is to install multiple sets of universal self-locking wheels on the bottom surface of the frame, which makes the frame easy to move and use.

[0012] This invention has the following advantages: The projector allows the electronic image of the product sample to be projected onto the negative pressure placement platform for comparison with the actual product. Simultaneously, a camera photographs the actual product and sends the image to the control center for automatic alignment with the electronic copy of the sample. The comparison results are then displayed on a touchscreen and screen for easy observation by staff. The combination of a negative pressure chamber and a negative pressure fan allows for suction and flattening of the actual product on the negative pressure placement platform, preventing wrinkles, ensuring accurate camera imaging, and improving the accuracy of product inspection and comparison by the control center.
