Description

[0002] During the processing and assembly of many products such as PCB boards and display screens, they need to be flipped for double-sided processing. In this process, flipping equipment is one of the indispensable and important devices. At present, the adsorption flipping equipment is driven by the flipping drive device to flip 180° after the adsorption table receives and adsorbs the product, and then releases the product to the specified position to complete the flipping. After that, the flipping drive device drives the adsorption table to flip back to its original position to receive the next product. Each time it flips, it is necessary to wait for the adsorption table to flip back to its original position before continuing to flip the next product, which takes a long time and has low flipping efficiency.

Thus, each time the suction device is driven to flip, it can complete the flipping of one product, eliminating the operation process of flipping and resetting the suction device, with high flipping efficiency and energy saving.

[0033] Specifically, the adsorption device includes a support frame 21, a plurality of connecting rods 22, and a plurality of suction cup assemblies 23. The connecting rods 22 are arranged in parallel on the support frame and are provided in two rows. A suction cup assembly 23 is connected to each connecting rod 22. The suction nozzles of the suction cup assemblies on the two rows of connecting rods 22 face in opposite directions to form two reverse adsorption surfaces.

The suction cup assemblies 23 of the two adsorption surfaces are respectively connected to a vacuum generator (not shown in the figure) through the air paths. Each air path is connected to one vacuum generator, enabling each vacuum generator to independently control the suction cup assembly 23 corresponding to the air path to adsorb or release the product. After the adsorption device rotates clockwise or counterclockwise by a preset angle, one adsorption surface can place the product that has been flipped, and the other adsorption surface can adsorb the product to be flipped. By alternately rotating clockwise and counterclockwise, the two adsorption surfaces work alternately, enabling the adsorption device to complete the flipping of the product every time it is driven to rotate, with high flipping efficiency and reduced energy consumption. Among them, the preset angle is 180°. In addition, a photoelectric induction device 25 is provided on each adsorption surface. The photoelectric induction device 25 is electrically connected to the control system.

The vacuum generator is connected to the air path inside the adsorption device through the rotary cylinder 3, and the rotary cylinder 3 is provided with the rotating inner cylinder 31 and the sealed outer cylinder 32, so that the inlet end joint is fixed and the outlet end rotates together with the adsorption device, thereby avoiding the trachea from being bent during the flipping process of the adsorption device.

[0036] Specifically, the air channel 33 is an L-shaped air channel. A plurality of annular grooves 36 are formed on the outer side of the connection end of the rotating inner cylinder 31 with the sealed outer cylinder 32. Each annular groove 36 and the inner side wall of the sealed outer cylinder 32 form an annular air channel 37. One end of the L-shaped air channel is connected to the air path inside the support frame 21, and the other end is connected to the annular air channel 37. The air inlet hole 34 is communicated with the L-shaped air channel through the annular air channel 37, so that when the rotating inner cylinder 31 rotates inside the sealed outer cylinder 32, the air inlet hole 34 and the air channel 33 can maintain a connected state.
