Description

Technical Field

[0001] The invention belongs to the field of hot stamping detection, and in particular relates to a hot stamping detection device. Background Art

[0002] From the manufacturing to the final consumption of goods, packaging is indispensable. In recent years, as consumers' aesthetic requirements for the appearance of goods continue to improve, the visual requirements for the outer packaging of goods are also getting higher and higher. The packaging box should not only play the functional role of protecting the goods, saving costs, facilitating transportation and facilitating calculation, but also play the value-added role of beautifying the goods, guiding consumption and increasing added value. The hot stamping process, because of its metallic texture and brightness, is widely used to realize the logo and important patterns of the packaging box.

[0003] Hot stamping equipment mainly uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metal effect. Hot stamping technology is widely used in packaging decoration in various industries, and the packaging can be made of plastic, paper and other materials.

[0004] During the hot stamping process, if the hot stamping process is unqualified, it will cause a series of problems such as the hot stamped images and texts to appear blurry and dizzy, the handwriting to be blurred and fuzzy, the edges of the images and texts to be uneven and unclear, the images and texts to be incomplete and irregular, with missing strokes, the images and texts to be blurred or blurred, the images and texts to be dull, the hot stamping quality to be unstable, and the bottom to leak after hot stamping.

[0005] Therefore, after the packaging production is completed, in order to avoid the output of defective products, a large number of people are often arranged to manually check the hot stamping paper for inspection. In this process, the human factor has a greater impact, and it is inevitable that defective products will occasionally be missed and output to the market. Summary of the invention

A controller is also provided on the detection platform. The infrared sensor and the telescopic rod are electrically connected to the controller. When the infrared sensor detects that the placement component appears under the second mounting plate, the infrared sensor transmits a signal to the controller, and the controller controls the movement of the telescopic rod to make the telescopic rod drive the second mounting plate and the dust removal component to descend, and the second mounting plate drives the placement component to rise through a linkage mechanism, so that the hot stamping on the placement component contacts the bottom of the dust cover, and then the power of the exhaust fan is turned on to clean the hot stamping surface, and the subsequent loading operation is not affected. After the cleaning is completed, the power of the exhaust fan is disconnected, and at the same time, the telescopic rod drives the second mounting plate to rise, and the second mounting plate drives the placement component to descend through the linkage mechanism, and the first tooth engages with the placement component again, and the conveyor belt can drive the placement component to move again.

A controller is also arranged on the detection platform 1, and the infrared sensor 6 and the telescopic rod 3 are both electrically connected to the controller. When the infrared sensor 6 detects that the placement component 4 appears below the second mounting plate 8, the infrared sensor 6 transmits a signal to the controller, and the controller controls the telescopic rod 3 to move, so that the telescopic rod 3 drives the second mounting plate 8 and the dust removal component 7 to descend, and the second mounting plate 8 drives the placement component 4 through the linkage mechanism 5. The placement component 4 rises, so that the hot stamping on the placement component 4 contacts the bottom of the dust cover 75, and then the power of the exhaust fan 71 is turned on to clean the hot stamping surface without affecting the subsequent loading operation. After the cleaning is completed, the power of the exhaust fan 71 is disconnected, and at the same time, the telescopic rod 3 drives the second mounting plate 8 to rise, and the second mounting plate 8 drives the placement component 4 to descend through the linkage mechanism 5, and the first latch tooth 45 engages with the placement component 4 again, and the conveyor belt 13 can drive the placement component 4 to move again.

The second mounting plate 8 drives the second rack 54 to descend, and the second rack 54 drives the transmission gear 53 to rotate. The transmission gear 53 drives the first rack 51 to rise, and the first rack 51 drives the placement plate 41 to rise, so that the first clamping tooth 45 and the second clamping tooth 14 are disengaged, and the conveyor belt 13 no longer drives the placement plate 41 to move. Finally, the surface of the placement plate 41 is in contact with the dust cover 7 5, the dust hood 75 completely covers the placement slot 46, the exhaust fan 71 is started, the exhaust fan 71 extracts the air inside the placement slot 46, and takes away the dust on the hot stamping surface, the dust will fall into the dust box 73, and then the power of the exhaust fan 71 is disconnected, the telescopic rod 3 drives the second mounting plate 8 and the dust removal assembly 7 to rise, the second mounting plate 8 drives the placement plate 41 to descend through the linkage mechanism 5, so that the first clamping tooth 45 is meshed with the second clamping tooth 14 again, and the conveyor belt 13 drives the placement plate 41 to continue to move through the second clamping tooth 14. When the placement plate 41 moves to the inside of the dark box 11, the optical sensor 17 will detect the hot stamping. Since the hot stamping has good reflective properties, the optical sensor 17 can accurately detect the color, shape and size of the hot stamping, and transmit the detection result to the processor, which determines whether the hot stamping is qualified, thereby greatly improving the accuracy of the detection result and avoiding the influence of human factors.

[0044] When the placement plate 41 is raised and the hot stamping is being cleaned, the conveyor belt 13 will continue to move, and the conveyor belt 13 will drive other placement components 4 to move. During this process, the staff can continue to load materials. Compared with the existing technology of pausing the conveyor belt 13 for cleaning, this device does not need to stop working, thereby improving work efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
