[0045] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0046] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0047] The present application provides a circuit board coating method, which is specifically applied to a coating device, wherein the coating device specifically includes a spray nozzle that can spray a water curtain-like spray material, wherein the water curtain-like refers to the spray material width between the spray nozzle and the circuit board to be coated being consistent. The specific steps of the method are as follows: Figure 1 As shown, the method can be specifically executed by a control unit of the spraying equipment, including:

[0048] S101, the control unit obtains the shape of the area to be coated of the circuit board to be coated and the coating width of the spray nozzle.

[0049] In the embodiment of the present application, when coating a circuit board, the control unit of the spraying equipment first obtains the shape of the to-be-coated area of ​​the circuit board to be coated and the coating width of the spraying nozzle.

[0050] Specifically, the circuit board to be coated can be divided into a coating area and a coating-forbidden area, wherein the coating-forbidden area may include the area of ​​the relay, the area requiring heat dissipation, and the like.

[0051] In one example, when the control unit acquires the shape of the area to be coated of the circuit board to be coated, the image acquisition device of the spraying equipment can be used to acquire the image of the circuit board to be coated to acquire the shape of the area to be coated of the circuit board to be coated, or the shape of the area to be coated of the circuit board to be coated can be selected or input by the user on the coating equipment. Specifically, the image acquisition device can be a camera.

[0052] S102, the control unit divides the area to be coated into a plurality of sub-areas to be coated according to the shape and coating width of the area to be coated.

[0053] In the embodiment of the present application, after obtaining the shape and coating width of the area to be coated, the control unit divides the area to be coated using the shape and coating width of the area to be coated to obtain a plurality of sub-areas to be coated.

[0054] S103, the control unit controls the spray nozzle to coat the multiple sub-areas to be coated to obtain a coating area with a preset coating thickness.

[0055] In an embodiment of the present application, after completing the division of the area to be coated, the control unit controls the spray nozzle to coat each sub-area to be coated in turn to obtain a coating area with a preset coating thickness, thereby completing the three-proof paint coating on the circuit board.

[0056] In one example, when the control unit controls the spray nozzle to coat the sub-area to be coated, it first obtains the coating parameters set by the user, and uses the coating parameters to control the spray nozzle to coat the sub-area to be coated. Specifically, the coating parameters may include the flow rate of the spray material and the moving speed of the spray nozzle. The flow rate of the spray material may be 20-60cm 3 / min, the moving speed of the spray nozzle can be 30-50mm / s.

[0057] In one example, the preset coating thickness of the embodiment of the present application is 45±5 μm.

[0058] According to the circuit board coating method provided by the embodiment of the present application, the shape of the area to be coated of the circuit board to be coated and the coating width of the spray nozzle are first obtained, and further, according to the shape of the area to be coated of the circuit board to be coated and the coating width of the spray nozzle, the area to be coated is divided into a plurality of sub-areas to be coated, and the spray nozzle is controlled to coat the plurality of sub-areas to be coated, so as to obtain a coating area with a preset coating thickness. The embodiment of the present application divides the area to be coated into a plurality of sub-areas to be coated according to the shape of the area to be coated of the circuit board to be coated and the coating width of the spray nozzle, so that the shape of the sub-areas to be coated can be regularized, the difficulty of coating can be reduced, and the coating efficiency can be improved. At the same time, by controlling the spray nozzle to coat each sub-area to be coated separately, it is ensured that the coating of each sub-area to be coated does not affect each other, and repeated coating is avoided, so that the thickness of the coating area can be ensured to be the same, and the coating quality is improved.

[0059] Furthermore, the shape of the area to be coated in the embodiment of the present application includes a regular shape, and dividing the area to be coated into a plurality of sub-areas to be coated according to the shape and coating width of the area to be coated may include the following steps:

[0060] S1021, the control unit obtains the coating width when the shape of the area to be coated is a regular shape.

[0061] In the embodiment of the present application, after obtaining the shape of the area to be coated, the control unit determines whether the shape of the area to be coated is a regular shape. Specifically, the regular shape in the embodiment of the present application may include a rectangle, an ellipse, and a Chinese-shaped circle. When the control unit confirms that the shape of the area to be coated is a rectangle, an ellipse, or a Chinese-shaped circle, it is determined that the area to be coated is a regular shape.

[0062] S1022, the control unit divides the area to be coated into a plurality of sub-areas to be coated that have the same regular shape and coating width.

[0063] In an embodiment of the present application, after determining that the area to be coated is a regular shape, the control unit obtains the regular shape and uses the regular shape and the coating width to divide the area to be coated into multiple sub-areas to be coated that have the same regular shape and coating width.

[0064] In an example, see Figure 2 As shown, it is a schematic diagram of a sub-region to be coated provided in an embodiment of the present application. Specifically, the circuit 100 includes a region to be coated 1, such as Figure 2 As shown, when the control unit determines that the area to be coated is a rectangle, the control unit divides the area to be coated 1 into a plurality of rectangular sub-areas 11 to be coated having a coating width using the rectangle and the coating width, that is, the shape of each sub-area to be coated 11 is the same as the shape of the area to be coated 1, which is a rectangle, and the width of each sub-area to be coated 11 is the same as the spraying width of the spray nozzle.

[0065] In one example, the rectangle of the embodiment of the present application includes a special rectangle square.

[0066] In an example, see Figure 3 As shown, it is a schematic diagram of another sub-region to be coated provided in an embodiment of the present application. Specifically, the circuit 100 includes a region to be coated 1, such as Figure 3 As shown, when the control unit determines that the area to be coated is an ellipse, the control unit divides the area to be coated 1 into a plurality of elliptical sub-areas 11 to be coated having a coating width using the ellipse and the coating width, that is, the shape of each sub-area to be coated 11 is the same as the shape of the area to be coated 1, which is an ellipse, and the width of each sub-area to be coated 11 is the same as the spraying width of the spray nozzle.

[0067] In one example, the ellipse of the embodiment of the present application includes a special elliptical circle.

[0068] In an example, see Figure 4 As shown, it is a schematic diagram of another sub-region to be coated provided in an embodiment of the present application. Specifically, the circuit 100 includes a region to be coated 1, such as Figure 4 As shown, when the control unit determines that the area to be coated is in the shape of a U-shaped letter "U", the control unit uses the ellipse and the coating width to divide the area to be coated 1 into a plurality of U-shaped sub-areas 11 to be coated having a coating width, that is, the shape of each sub-area to be coated 11 is the same as the shape of the area to be coated 1, which is a U-shaped letter "U", and the width of each sub-area to be coated 11 is the same as the spraying width of the spray nozzle.

[0069] The embodiment of the present application obtains the shape of the area to be coated, and when the shape of the area to be coated is a regular shape, divides the area to be coated into the plurality of sub-areas to be coated which have the same regular shape and a coating width, so that the shape of the sub-areas to be coated can be regular, the difficulty of coating can be reduced, and the coating efficiency can be improved. At the same time, the spray nozzle is controlled to coat each sub-area to be coated separately, thereby ensuring that the coating of each sub-area to be coated does not affect each other, avoiding repeated coating, and thus ensuring that the thickness of the coating area is the same, thereby improving the coating quality.

[0070] Further, in the embodiment of the present application, the shape of the area to be coated in the embodiment of the present application may also include an irregular shape. According to the shape of the area to be coated and the coating width, the area to be coated is divided into a plurality of sub-areas to be coated, which may include the following steps:

[0071] S1023, when the shape of the area to be coated is irregular, the control unit divides the area to be coated into a first area to be coated with a regular shape and a second area to be coated with an irregular shape.

[0072] In the embodiment of the present application, after obtaining the shape of the area to be coated, the control unit determines whether the shape of the area to be coated is an irregular shape. Specifically, if the control unit determines that the boundary of the area to be coated is an irregular line, the control unit determines that the shape of the area to be coated is an irregular shape. When the control unit determines that the area to be coated is an irregular shape, the control unit first divides the area to be coated for the first time, that is, divides the area to be coated into a first area to be coated with a regular shape and a second area to be coated with an irregular shape.

[0073] In an example, see Figure 5 As shown, it is another schematic diagram of a sub-area to be coated provided in an embodiment of the present application. When the control unit determines that the area to be coated 1 is irregular in shape, the control unit divides the coating area into a first area to be coated 12 with a regular shape and a second area to be coated 13 with an irregular shape. Specifically, the preferred regular shape in the embodiment of the present application is a rectangle, that is, the coating area is divided into a first area to be coated 12 with a rectangular shape and a second area to be coated 13 with an irregular shape.

[0074] S1024, the control unit determines the second area to be coated as the first sub-area to be coated, divides the first area to be coated into a plurality of second sub-areas to be coated having the same regular shape and a coating width, so as to obtain a plurality of sub-areas to be coated.

[0075] In an embodiment of the present application, after completing the first division, the control unit determines the irregular area after the first division as the first sub-area to be coated, and performs a second division on the first area to be coated with a regular shape, dividing the first area to be coated with a regular shape into a plurality of second sub-areas to be coated which have the same regular shape and a coating width, so as to obtain a plurality of sub-areas to be coated.

[0076] In one example, when the control unit performs the second division of the first area to be coated with a regular shape, the control unit obtains the regular shape and divides the first area to be coated into a plurality of sub-areas to be coated with the same regular shape and coating width using the regular shape and coating width.

[0077] For an example, see Figure 5 As shown, when the first rectangular area to be coated is divided for the second time, the width of the first area to be coated 12 and the coating width of the spray nozzle are obtained, and then the first area to be coated 12 is divided into a plurality of rectangular sub-areas to be coated with coating widths using rectangles.

[0078] Furthermore, controlling the spray nozzle of the embodiment of the present application to coat multiple sub-areas to be coated to obtain a coating area with a preset coating thickness may include the following steps:

[0079] S1031, when the control unit determines that the shape of the area to be coated is an irregular shape, the control unit controls the spray nozzle to first coat the first sub-area to be coated, and then controls the spray nozzle to coat multiple second sub-areas to be coated to obtain a coating area with a preset coating thickness.

[0080] In the embodiment of the present application, when the control unit determines that the shape of the area to be coated is irregular, the control unit first controls the spray head to coat the first sub-area to be coated with a regular shape, so as to preferentially ensure the coating thickness of the regular shape area. After the coating of the first sub-area to be coated with regular characteristics is completed, the control unit controls the spray head to coat the second irregular shape area to be coated, and then completes the coating of the entire area to be coated, thereby obtaining a coating area with a preset coating thickness.

[0081] In one example, when controlling the spray nozzle to coat the irregularly shaped second area to be coated, the control unit can reduce the spray flow rate of the spray nozzle and coat the irregularly shaped second area to be coated multiple times to ensure that the irregularly shaped second area to be coated is coated and the coating quality is guaranteed.

[0082] Furthermore, after obtaining the coating area, the circuit board coating method of the embodiment of the present application performs high-temperature curing on the coating area to obtain a coating area with a preset coating. Specifically, the curing temperature can be 60-75 degrees Celsius.

[0083] For further information, see Figure 6 As shown, it is a schematic diagram of the structure of the spray nozzle provided by the embodiment of the present application, the spray nozzle comprises an upper shell 2 and a lower shell 3, the upper shell 2 and the lower shell 3 are connected by mounting bolts 6, a receiving groove 16 is provided in the upper shell 5, a power assembly is arranged in the receiving groove 16, and comprises a spring 4, a first slider 5 and an air inlet 15, one end of the spring 4 is fixedly connected to the receiving groove 16, and the other end is fixedly connected to the first slider 5, one end of the first slider 5 is connected to the spring 4, and the other end is connected to the air inlet 15, and the first slider 5 slides in the receiving groove 16 under the action of gas to deliver the gas to the storage tube 8. Specifically, when the gas enters through the air inlet 15, the first slider 5 compresses the spring to move under the action of the gas to open the storage tube 8, and then the gas enters the storage tube 8, so as to provide power for the spray material stored in the storage tube 8, so that the stored material can be sprayed out through the spray port 11, and when the gas is stopped, the first slider 5 moves under the elastic force of the spring 4 to seal the storage tube 8.

[0084] The spray nozzle also includes a sealing member, which is arranged in the storage tube 8. One end of the sealing member is fixedly connected to the first slider 5. The sealing member opens or closes the spray port 11 under the drive of the first slider 5. Specifically, the sealing member is a ejector pin 9. The needle head of the ejector pin 9 is connected to the spray port 11. The other end of the ejector pin 9 is fixedly connected to the first slider 5. When the first slider 5 compresses the spring 4 and moves under the action of gas, the ejector pin 9 can be driven to move to open the spray port 11 so that the spray material can be sprayed out. When the gas stops entering, the first slider 5 moves under the action of the spring 4 to close the sealing port 11.

[0085] Furthermore, the storage tube 8 of the present invention is also provided with a sealing valve 7, which is used to seal the spraying material in the storage tube 8. At the same time, the sealing valve can also allow gas to pass through, so that the spraying material in the storage tube 8 can be sprayed out in a water curtain shape under the action of the gas.

[0086] For further information, see Figure 7 As shown, it is an enlarged view of the spray port provided in an embodiment of the present application. The spray port 11 is cylindrical and is provided with a first V-shaped opening (lower opening) and a second V-shaped opening (upper opening). The first V-shaped opening (lower opening) is connected to the storage tube. The spray material enters the first V-shaped opening from the storage tube and is sprayed out from the second V-shaped opening. Since the second V-shaped opening has a certain width, the spray material sprayed from the second V-shaped opening is in the shape of a water curtain with consistent upper and lower widths.

[0087] The spray nozzle of the embodiment of the present application can spray the spray material in a water curtain shape, thereby making the spray shape of the spray material neat, avoiding splashing during the coating process, thereby ensuring uniform coating thickness and improving coating quality.

[0088] Furthermore, the present application provides a circuit board coating device, which is applied to a spraying device, wherein the spraying device includes a spray nozzle that can spray a water curtain-like spray material, such as Figure 8 As shown, the device comprises:

[0089] An acquisition module 801 is used to acquire the shape of the area to be coated of the circuit board to be coated and the coating width of the spray nozzle;

[0090] A division module 802 is used to divide the area to be coated into a plurality of sub-areas to be coated according to the shape of the area to be coated and the coating width;

[0091] The control module 803 is used to control the spray nozzle to coat the plurality of sub-areas to be coated to obtain a coating area with a preset coating thickness.
