[0070] Please refer to the appendix Figure 5 In order to spray the plate comprehensively and ensure the uniformity of spraying, specifically, a three-axis motion mechanism 7 is installed on the top corners of the base 1 through support columns 6, and the spraying device 9 is installed on the three-axis motion mechanism 7. The spraying device 9 specifically includes a spraying main body 9.1, which is provided with a driving device inside and is fixed on the three-axis motion mechanism 7;

[0071] A spray head 9.2 is arranged at the bottom of one end of the spraying main body 9.1 and realizes spraying through the drive of the driving device;

[0072] A paint adding hose 9.3 is connected to the spraying main body 9.1 at one end.

[0073] In order to facilitate driving the spraying device to move and lift randomly, please refer to the appendix Figure 1 and the appendix Figure 5 Furthermore, the three-axis motion mechanism 7 is a conventional existing structure, which can drive the spraying device 9 to perform three-axis motion and fixation in space. The specific structure of any one axis is a support slide 7.1, a threaded shaft 7.3 that can rotate on the support slide 7.1, and a drive motor 7.2 that drives the threaded shaft 7.3 to rotate.

The slider 7.4 is threadedly connected to the threaded shaft 7.3, and the structures of the other two axes are the same as the above, forming a spatial three-axis motion mechanism.

[0074] Please refer to the appendix Figure 6 and the appendix Figure 7 In order to facilitate pushing the sprayed plate from the flipping device into the support conveying device for conveying out and realizing automatic continuous spraying of the plate, specifically, the pushing device 10 includes a third rotating shaft 10.3, which is rotatably connected between the support columns 6 and keeps the third rotating shaft 10.3 parallel to the conveying direction of the support conveying device 3;

[0075] The third driving motor 10.1 is arranged on the side of the support column 6 and is connected to the third rotating shaft 10.3 through a belt transmission mechanism 10.2;

[0076] The rotating rod 10.4 is arranged in parallel outside the third rotating shaft 10.3 and is fixed to the third rotating shaft 10.3;

[0077] One end of the push plate 10.6 is sleeved on the outer end of the third rotating shaft 10.3 to maintain linear sliding, and the other end extends above the plate 8 of the flipping device 5;

[0078] The rodless cylinder 10.5 is sleeved on the outer end of the rotating rod 10.4 to maintain sliding and is connected to the push plate 10.6.

[0079] Before the spraying device is used, according to the size of the plate in advance, by rotating the screw 4.2 in the adjusting assembly 4, the support conveying device 3 and the flipping device on the sliding plate 11 are driven to move along the sliding rail 2, ensuring that both sides of the plate can be inserted into the conveying grooves or sliding grooves of the two groups of support conveying devices 3 or flipping devices 5.

[0080] Subsequently, the third driving motor 10.1 is started to drive the third rotating shaft 10.3 to rotate, driving the rotating rod 10.4, the rodless cylinder 10.5 and the push plate 10.6 to flip outwards. Then, the second driving motor 5.1 is started to drive the second rotating shaft 5.5 to rotate. Under the action of the transmission mechanism in the transmission box 5.2, the second support clamping plate 5.4 is driven to flip, keeping the sliding groove on the side of the second support clamping plate 5.4 corresponding to the conveying groove on the support conveying device 3 at one end. Finally, the first conveying motor 3.2 is started to drive the first rotating shaft 3.3 to rotate, thereby driving the tension belt in the conveying groove to move. The plate 8 is placed in the conveying groove of the first support clamping plate 3.4 and is conveyed through the tension belt until it enters the sliding groove of the second support clamping plate 5.4. Since one end of the sliding groove is sealed, the fixing of the plate 8 can be realized.

[0081] Then, according to the induction device (such as a sensor) on the spraying device 7 and the external control system (such as a PLC control system), the three-axis motion mechanism 7 is controlled to move to a suitable height and position, and then the spraying main body 9.1 is controlled to spray. After spraying, the external control system controls the three-axis motion mechanism 7 to return to its original position. At the same time, the second driving motor 5.1 is started, and through the rotation of the second rotating shaft 5.5 and the transmission of the transmission mechanism in the transmission box 5.2, the second support clamping plate 5.4 and the plate 8 are driven to flip 180° (note that when flipping, keep the open end of the sliding groove facing upwards to avoid the falling off of the plate), so that the open end of the sliding groove of the second support clamping plate 5.5 corresponds to the conveying groove of the support conveying device 3 at the other end.

[0082] After the flipping is completed, the three-axis motion mechanism 7 is controlled by the induction device (such as a sensor) on the spraying device 7 and the external control system (such as a PLC control system) to move and lift for re-spraying, so as to achieve spraying on both sides of the plate. After the spraying is completed, the three-axis motion mechanism 7 returns to its original position. At this time, the rodless cylinder 10.5 is activated to move the push plate 10.6 to the outside of the closed end of the chute. Then, by starting the third driving motor 10.1, the third rotating shaft 10.3 is driven to rotate, so as to drive the push plate 10.6 to rotate around the third rotating shaft 10.3 to the lower part of the end of the plate 8. Finally, the rodless cylinder 10.5 is activated to drive the push plate 10.6 to move, so as to push the plate 8 to move from the chute of the second support clamping plate 5.4 towards the conveying chute of the other end support conveying device 3, realizing automatic spraying of the plate 8. Finally, after the plate is pushed out, each motion device returns to its original position and waits for the spraying of the subsequent plate.
