[0042] See attached Figure 1 and Figure 8 As shown, in the utility model, the rotary flushing assembly 5 includes a telescopic cylinder 51 installed on the outer wall of the protective shell 4, a reversing plate 52 installed on the telescopic cylinder 51, a connecting plate 53 installed on the reversing plate 52 and passing through the protective shell 4, and a rotating structure 54 and a cleaning structure 55 installed on the connecting plate 53.

[0043] The utility model uses the telescopic cylinder 51 as the mobile power source of the rotating structure 54 and the cleaning structure 55 to avoid interference between the rotating structure 54 and the cleaning structure 55 and the reversing and flipping of the blank, ensuring that the blank can be reversed and flipped; the reversing plate 52 is used to reverse the movement of the telescopic cylinder 51, so that the telescopic rod of the telescopic cylinder 51 does not need to enter the protective shell 4, which is convenient for maintenance of the telescopic cylinder 51; the connecting plate 53 is used to provide an installation position for the rotating structure 54 and the cleaning structure 55. It should be particularly noted that the telescopic cylinder can be an electric cylinder or a pneumatic cylinder.

[0044] See attached Figure 8 As shown, in the utility model, an avoidance groove 41 is provided on the protective shell 4; the connecting plate 53, the rotating structure 54 and the cleaning structure 55 penetrate the protective shell 4 through the avoidance groove 41; wherein the rotating structure 54 includes a rotating motor 541 installed on the top of the connecting plate 53, and a rubber friction column 542 installed on the rotating motor 54; the cleaning structure 55 includes a mounting plate 551 installed on the bottom of the connecting plate 53, a cleaning nozzle 552 installed on the mounting plate 551, and a water inlet pipe 553 connected to the cleaning nozzle 552, and the water inlet pipe 553 is connected to the main water tank.

[0045] The utility model arranges the avoidance groove 41 so that the connecting plate 53 can drive the rotating structure 54 and the cleaning structure 55 to move. The rotating motor 541 is arranged as a rotating power source to drive the blank to rotate so that the entire blank can be cleaned. The rubber friction column 542 is arranged to transmit the power of the rotating motor 541, that is, the friction between the rubber friction column 542 and the blank can drive the blank to rotate, and since the rubber material is used, the blank will not be damaged. The cleaning nozzle 552 is arranged to spray clean water to clean the blank. It should be particularly noted that the water inlet pipe 553 is connected to the water outlet of the water pump, and the water inlet of the water pump is connected to the main water tank.

[0046] It should be particularly noted that the rotation directions of the rotary motors 541 in the two sets of rotary flushing components 5 are opposite.

[0047] See attached Figure 1 — Figure 8 As shown, the use process of the utility model is as follows:

[0048] In the first step, the blank is placed by the robot arm, and the infrared sensor 321 senses that the blank is placed, and then the blank is reversed and cleaned; specifically, when the robot arm places the blank on the blank support assembly 3, the infrared sensor 321 is blocked, which means that the blank is being placed. When the blank is placed, the infrared sensor 321 is re-shot, and then the robot arm is reset and the infrared sensor 321 is blocked again. After blocking, it means that the blank is placed, and the blank can be reversed and flipped;

[0049] In the second step, the telescopic cylinder 51 starts to work, driving the rotating structure 54 and the cleaning structure 55 to move toward the blank through the reversing plate 52 and the connecting plate 53 until they move to the designated position, at which time the rubber friction column 542 contacts the blank;

[0050] In the third step, the rotating motor 541 starts to work, driving the rubber friction column 542 to rotate; at the same time, the cleaning structure 55 starts to work to rinse the blank; specifically, the external water pump starts to work, pumping water from the main water tank, and after pressurization, it is sprayed out from the cleaning nozzle 552 through the water inlet pipe 553 to clean the blank;

[0051] Step 4: After the rotating motor 541 has worked for a specified time, it stops working. At the same time, the water pump also stops working. The telescopic cylinder 51 drives the rotating structure 54 and the cleaning structure 55 to reset through the reversing plate 52 and the connecting plate 53.

[0052] Step 5: After the telescopic cylinder 51 is reset, the reversing member 2 starts to work, driving the blank to rotate and turn over, preparing for the robot to take it.

[0053] It should be noted that the control in the present application is performed by a PLC controller, wherein a proximity switch can be used for distance limiting, and the working time of the rotating motor can be controlled by a timer of the PLC controller.

[0054] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
