The method for controlling the thickness of the target spray coating according to a preferred embodiment of the present invention is used for spraying the surface to be sprayed of the target to form the spray coating, so as to prevent two adjacent targets from interfering with each other. In this embodiment, the target is a semiconductor, and the surfaces to be sprayed are the upper surface and the side surfaces of the semiconductor.
In the prior art, a spray head and a surface to be sprayed are arranged to be relatively parallel to perform spraying work. When the surface to be sprayed is the upper surface of the semiconductor, the spray head parallel to the upper surface can well realize the spray coating with the required thickness, and when the surface to be sprayed is the side surface, the spray head is difficult to form the spray coating with the thickness consistent with the thickness of the spray coating on the upper surface or the spray coating with the thickness thicker than the thickness of the spray coating on the side surface. If the spray coating layer on the side needs a certain thickness, the spray head needs to be repeatedly sprayed on the side, which not only wastes time, but also increases the cost of the spray coating.
In order to solve the above problem, in the present embodiment, the heads 1 are inclined and arranged in pairs on both sides of the target 2 (only one is shown in the drawing), and the two heads 1 are arranged symmetrically with respect to the target 2 such that the two heads 1 correspond to the side faces 22 of one target 2, respectively. Under the action of external force, the two spray heads 1 can move in the horizontal direction relative to the target object 2, and simultaneously spray two side surfaces 22 of the target object 2 corresponding to the positions of the spray heads 1 and the upper surface 21 of the target object 2, so that the upper surface 21 and the side surfaces 22 of the target object 2 can obtain a sprayed layer 25 with required thickness. The head 1 is higher than the upper surface 21 of the target 2 in the height direction of the target 2. In this embodiment, the force for driving the nozzle to move is a driving force generated by a driving member, such as a motor or an air cylinder.
In practical applications, the difference in the inclination angle of the head 1, the difference in the distance between the head 1 and the target 2, and the like directly affect the ejection height of the head 1, that is, the ejection range of the head 1. Due to the different heights of the different objects 2 or the different thicknesses of the sprayed layer 25 required for the side faces 22 of the different objects 2. It is therefore necessary to control the thickness of the sprayed layer 25 formed on the side face 22 of the object 2 by the head 1 by adjusting the inclination angle of the head 1 and the interval between the head 1 and the object 2. For the sake of easy understanding, in the present embodiment, the change of the spray head 1 in the sprayed layer 25 sprayed to the side surface 22 of the object 2 can be explained by the relation of trigonometric functions.
Specifically, referring to fig. 1, since the two nozzles 1 are symmetrically disposed and have the same structure and position, the following description will be made by taking only one nozzle 1 spraying the target object 2 to form the spray coating 25 as an example.
The spray head 1 has a first position 3 and a second position 4; the side surface 22 of the target 2 has a first spray point and a second spray point, and the spray head 1 moves from the first position 3 to the second position 4 to form a sprayed layer 25 on the side surface 22 of the target 2 from the first spray point to the second spray point;
the shortest straight-line distance from the spray head 1 to the side surface 22 in the horizontal direction is a;
the shortest straight line distance of the spray head 1 in the vertical direction is b;
the straight-line distance from the first position 3 to the first jet point is c, namely the length of the jet line is c;
the included angle between the straight line a and the straight line c is A;
the angle of the included angle a is adjusted to change the ratio of a to b to control the thickness of the sprayed layer 25.
The first position 3 is an initial position of the head 1, and the second position 4 is a position from which the head 1 ejects to a second ejection point. In the present embodiment, the side surface 22 of the object 2 has a top end 23 and a bottom end 24, the bottom end 24 being a first ejection point, the top end 23 being a second ejection point, and the head 1 being disposed higher than the second ejection point. In other embodiments, the first injection point and the second injection point may be any two height points on the side surface 22, and the positions of the first injection point and the second injection point are not specifically limited as long as the first injection point and the second injection point are both on the spraying track formed by the movement of the spray head 1.
The position of the spray head 1 is determined so that the shortest straight-line distance b of the spray head 1 in the vertical direction is kept constant, and the angle of the included angle A is adjusted to change the ratio of a to b. I.e. b remains unchanged, the value of a is changed by adjusting the angle of a. In this embodiment, the included angle a is in the range of 1 to 45 °, so that the spray coating 25 formed on the side surface 22 by the spray head 1 has a certain thickness.
The shortest straight distance from the top end 23 to the bottom end 24 is b 1;
the top end 23 is provided with a first extension surface in the horizontal direction, and the shortest straight-line distance from the spray head 1 to the first extension surface in the vertical direction is b 2; b1+ b2 ═ b.
The linear distance from the first position 3 to the second position 4 is a 1;
the top end 23 has a second extension surface in the vertical direction, and the shortest straight-line distance from the spray head 1 at the second position 4 to the second extension surface in the horizontal direction is a 2; a1+ a2 ═ a.
The spray head 1 also has a third position 5 and the object 2 has a third spray point. In this embodiment, the third position 5 is a position from the head 1 to a third injection point, which is a half of the upper surface 21 of the target 2.
Specifically, the nozzle 1 is rotated so that the included angle a is 45 °, as defined by the reference mark, and the ratio of a to b is 1, i.e., a is b. In this case, the thickness of the sprayed layer 25 formed by the spraying line c on the straight line b during the movement of the spray head 1 from the first position 3 to the second position 4 is the first thickness; the thickness of the jet formed by the jet line c on the upper surface 21 of the target 2 is the second thickness in the process that the spray head 1 moves from the second position 4 to the third position 5; at this time, the first thickness is the same as the second thickness.
If the side 22 of the target 2 requires a thicker spray coating 25 than the spray coating 25 on the upper surface 21, the linear distance b remains unchanged, and the nozzle 1 is rotated under the action of the external force, so that the included angle a is greater than 0 ° and less than 45 °, and it can be known from the feature of the right triangle that the ratio of a to b is greater than 1, that is, the linear distance a is greater than the linear distance b, thereby obtaining that the first thickness is greater than the second thickness. It should be noted that the specific thickness of the sprayed layer 25 on the side surface 22 is determined according to the angle of the included angle a and the linear distance a.
In other embodiments, since the spraying distance of the spraying head 1 has a certain limitation, when the height of the target object 2 is high, that is, the first spraying point is not in the spraying range of the spraying head 1, the deflection angle of the spraying line becomes large, so that the spraying layer 25 sprayed on the side surface 22 by the spraying head 1 has poor effect or the spraying layer 25 is thin, and the difference between the spraying layer 25 and the upper surface 21 of the target object 2 is large. Because, in this case, it is necessary to rotate the head 1 by an external force so that the included angle a is greater than 45 ° to shorten the length of the straight line c, and the spraying of the side surface 22 of the higher object 2 by the head 1 is achieved, but the thickness of the sprayed layer 25 formed on the side surface 22 is still thin at this time, it is necessary to repeatedly spray the side surface 22 so that the thickness of the sprayed layer 25 of the side surface 22 coincides with the thickness of the upper surface 21 or so that the side surface 22 forms the sprayed layer 25 thicker than the thickness of the sprayed layer 25 of the upper surface 21.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
