Embodiment 1
[0030] see figure 1 , a method for improving the uniformity of automatic spray coating thickness, comprising the steps of:
[0031] a. Set the spraying width of the spray gun of the spraying robot to L, divide one spraying width into N times to overlap, and determine the front and rear overlapping distance D 1 =L / N, arc radius R= D 1 / 2;
[0032] b. Write the spraying program for the parts, first determine the area to be sprayed, determine the left and right boundaries of the two different spraying areas, then insert the starting point in the area to be sprayed, and set the starting point to shoot the command, and then make a straight line trajectory, the distance between the end point of the straight trajectory and the boundary is D 2 , and at the same time insert the command to close the gun at the end of the straight line trajectory;
[0033] c. Insert the first 1 / 4 arc, and set the shooting command at the end of the arc; then insert the second 1 / 4 arc; then insert a st...
Embodiment 2
[0037] see figure 1 , a method for improving the uniformity of automatic spray coating thickness, comprising the steps of:
[0038] a. Set the spraying width of the spray gun of the spraying robot to L, divide one spraying width into N times to overlap, and determine the front and rear overlapping distance D 1 =L / N, arc radius R= D 1 / 2;
[0039] b. Write the spraying program for the parts, first determine the area to be sprayed, determine the left and right boundaries of the two different spraying areas, then insert the starting point in the area to be sprayed, and set the starting point to shoot the command, and then make a straight line trajectory, the distance between the end point of the straight trajectory and the boundary is D 2 , and at the same time insert the command to close the gun at the end of the straight line trajectory;
[0040] c. Insert the first 1 / 4 arc, and set the shooting command at the end of the arc; then insert the second 1 / 4 arc; then insert a st...
Embodiment 3
[0045] see figure 1 , a method for improving the uniformity of automatic spray coating thickness, comprising the steps of:
[0046] a. Set the spraying width of the spray gun of the spraying robot to L, divide one spraying width into N times to overlap, and determine the front and rear overlapping distance D 1 =L / N, arc radius R= D 1 / 2;
[0047] b. Write the spraying program for the parts, first determine the area to be sprayed, determine the left and right boundaries of the two different spraying areas, then insert the starting point in the area to be sprayed, and set the starting point to shoot the command, and then make a straight line trajectory, the distance between the end point of the straight trajectory and the boundary is D 2 , and at the same time insert the command to close the gun at the end of the straight line trajectory;
[0048] c. Insert the first 1 / 4 arc, and set the shooting command at the end of the arc; then insert the second 1 / 4 arc; then insert a st...
