[Technical field]

[0001] The invention relates to the technical field of rotating mechanisms, in particular to the technical field of a product online high-speed rotating device. [Background technology]

[0002] Before the products conveyed by the conveyor belt are processed, they usually need to be corrected by a correction device to keep the deflection angles of each product consistent, thereby ensuring the processing quality of the products. During each correction, the conveyor belt needs to be temporarily paused to make the products temporarily still, thereby ensuring that the conveyor belt and the correction device maintain a normal working rhythm. However, the pause will in turn lead to a decrease in processing efficiency, which needs to be solved urgently. [Summary of the invention]

[0029] Working process of the present invention:

[0030] See also Figure 8 When the deflected product is conveyed by the conveyor belt 1 to the bottom of the visual module, the visual module immediately detects its deflection angle. At the same time, a set of adjustment mechanisms 3 located closest to the input end of the conveyor belt 1 starts to work. The lever motor 312 first drives the screw to rotate through the transmission assembly, so that the nut 313 moves along the screw, so that the suction cup 39 is located directly above the product to be corrected, and then according to the transmission speed of the conveyor belt 1, the suction cup 39 and the product to be corrected move synchronously along the transmission direction. Then, the cylinder 34 drives the suction cup 39 to move vertically downward through the telescopic rod until the rubber disc 393 is close to the top surface of the product. Then, the vacuum generator allows the air between the rubber disc 393 and the product to leave along the guide head 392, the joint 391, the ventilation block 37, the duct 38 and the air pipe, so that the suction cup 39 generates negative pressure and sucks the product. Subsequently, the adjustment motor 33 drives the suction cup 39 to rotate, thereby driving the product to rotate until the product rotates to a uniform deflection angle. After the deflected product is corrected, the positioning mechanism 3 returns to its original position or adjusts the angle of the next product to be corrected. In addition, if the positioning mechanism 3 is too late to process, the next or next group of positioning mechanisms 3 located at the rear can correct the product to be corrected.

[0031] The present invention installs a visual module that can detect the deflection angle of the product on the input end of the conveyor belt, and uses a support frame to install at least two groups of positioning mechanisms along the conveying direction of the conveyor belt. The mutual cooperation between the groups of positioning mechanisms can be used to adjust the angles of all products to be corrected. The whole process does not require the conveyor belt to stop, which can greatly improve the product correction efficiency; the connection between the positioning motor, the cylinder and the ventilation block is realized by adopting a support plate with an opening on the extension part and a limit plate with a sleeve, which does not affect the normal operation of the positioning motor and can effectively improve the installation stability of the positioning motor and the ventilation block; by arranging the ventilation block and the duct, the airflow direction is reversed, so that the rubber disc is set downward to ensure stable adsorption of the product.
