Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying protection device for a power panel with side holes. Background Technology

[0002] like Figure 1 and Figure 2 The image shows a power supply panel that can seal over a power supply, providing protection and waterproofing. The power supply panel has side holes. After manufacturing, the outer side of the power supply panel needs to be painted to coat it with a layer of paint, and the walls of the side holes also need to be painted. However, it is important to note that the inner side of the power supply panel cannot be painted.

[0003] In the existing technology, the method for spraying this power panel with side holes is as follows: First, high-temperature adhesive tape is pasted onto the inside of the side holes of the power panel; then, a fixture is prepared, and the power panel is placed on the fixture, with the upper side of the fixture tightly connected to the edge of the power panel; next, the fixture and the power panel are placed together in the working position of the spraying equipment, and the spraying equipment sprays the power panel; then, the fixture and the power panel are removed together, and the high-temperature adhesive tape on the inside of the side holes is peeled off; finally, the paint burrs adhering to the inside of the side holes are removed, and the spraying is completed.

[0004] However, the existing spraying method for power panels with side holes has the following disadvantages: (1) There is a gap between the high-temperature adhesive tape and the inside of the side hole of the power panel. After the spraying operation is completed and the high-temperature adhesive tape is removed, there will be many burrs on the inside of the side hole of the power panel. These burrs are difficult to remove after curing, which can easily lead to increased labor costs and unstable product quality; (2) High-temperature adhesive tape needs to be pasted before spraying and needs to be removed after spraying. The labor cost is high, and the high-temperature adhesive tape is consumed seriously, resulting in high material costs; (3) When the power panel is placed on the fixture, since there is no other mechanism for positioning between the power panel and the fixture, it is easy to cause a large gap between the fixture and the power panel due to shaking, tilting, etc., which causes the paint to enter the inside of the power panel from the gap during spraying. The paint that enters the inside of the power panel will adhere to the inside of the power panel, resulting in poor spraying. Utility Model Content

[0005] The technical problem this utility model aims to solve is to address the shortcomings of the prior art by providing a spray protection device for a power panel with side holes. This spray protection device can prevent burrs from forming on the inside of the side holes of the power panel after spraying, and eliminates the need for high-temperature adhesive tape, significantly reducing labor costs and improving product spraying quality. At the same time, this spray protection device can provide dual positioning for the power panel, preventing large gaps between the protective cavity and the power panel due to shaking or tilting, and preventing paint from entering the interior of the power panel during spraying.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a spray protection device for a power panel with side holes, comprising a protective cavity and a hole-plugging mechanism. The protective cavity includes a cavity base plate, and cavity side plates are connected around the cavity base plate. The upper end of the cavity side plates is used to support and position the inner edge of the power panel. The cavity side plates have notches. When the cavity side plates support and position the power panel, the side holes of the power panel are located at the notches of the cavity side plates. The hole-plugging mechanism includes a cylinder, a push block, and a flexible plug. The cylinder is installed on the cavity base plate, and the piston rod of the cylinder extends toward the notches of the cavity side plates and is connected to the push block. The flexible plug is installed on one side of the push block and is used to block or loosen the inner end of the side holes of the power panel.

[0007] In the above technical solution, each end of the cavity side plate has a notch, and there are two plugging mechanisms, one of which corresponds to one of the notches and the other corresponds to the other notch.

[0008] In the above technical solution, the cylinder is a double piston rod cylinder, and the flexible plug is a silicone plug.

[0009] In the above technical solution, the shape of the upper end of the cavity side plate matches the shape of the inner edge of the power panel.

[0010] The beneficial effects of this utility model are: (1) When the power panel is supported and positioned by the side plate of the cavity, the cylinder can push the flexible plug to block the inner end of the side hole of the power panel through the push block. Since the flexible plug can be pushed by the cylinder, the flexible plug and the inner end of the side hole of the power panel achieve an interference fit and the connection is very tight, avoiding the generation of gaps. Therefore, after spraying, the inner end of the side hole of the power panel will not produce burrs, saving the labor cost of burr removal and significantly improving the spraying quality of the product; (2) This utility model uses a hole-blocking mechanism to block or loosen the inner end of the side hole of the power panel. (2) No high-temperature adhesive tape is needed, saving the labor cost of pasting and tearing high-temperature adhesive tape, and no high-temperature adhesive tape is consumed, thus avoiding material waste; (3) The upper end of the cavity side plate of this utility model can support and position the inner edge of the power panel, playing the first positioning role, while the flexible plug of the hole-blocking mechanism can play the second positioning role when it is pressed against the inner end of the side hole of the power panel. Under the dual positioning role, the problem of large gap between the protective cavity and the power panel due to shaking, tilting and other reasons can be avoided, and the problem of paint entering the inside of the power panel during spraying can be avoided.

[0016] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown, a power panel 100 is provided. This power panel 100 can seal and cover a power source, providing protection and waterproofing. The power panel 100 has side holes 101 on its side. After the power panel 100 is manufactured, its outer surface needs to be painted to coat it with a layer of paint. At the same time, the walls of the side holes 101 are also coated with paint. However, it should be noted that the inner surface of the power panel 100 cannot be painted.

[0018] like Figure 3 and Figure 4 As shown, in conjunction with reference Figure 1 and Figure 2 This utility model is a spray protection device for a power panel with side holes, including a protective cavity 1 and a hole-blocking mechanism 2. The protective cavity 1 includes a cavity base plate 11, and cavity side plates 12 are connected around the cavity base plate 11. The upper end of the cavity side plates 12 is used to support and position the inner side of the edge of the power panel 100. The cavity side plates 12 have a notch 13. When the cavity side plates 12 support and position the power panel 100, the side hole 101 of the power panel 100 is located at the notch 13 of the cavity side plates 12. The hole-blocking mechanism 2 includes a cylinder 21, a push block 22 and a flexible block 23. The cylinder 21 is installed on the cavity base plate 11. The piston rod of the cylinder 21 extends toward the notch 13 of the cavity side plates 12 and is connected to the push block 22. The flexible block 23 is installed on one side of the push block 22 and is used to block or loosen the inner end of the side hole 101 of the power panel 100.

[0019] The method of using this utility model spray protection device is as follows: First, place the power panel 100 with side holes on the cavity side plate 12 of the protective cavity 1, so that the upper end of the cavity side plate 12 supports and positions the inner edge of the power panel 100, with the outer side of the power panel 100 facing outward. The inner edge of the power panel 100 has an annular groove 102, and the upper end of the cavity side plate 12 matches the shape of the annular groove 102, so that it can be inserted into the annular groove 102. Then, control the cylinder 21 to work, and the piston rod of the cylinder 21 extends outward, driving the push block 22 to push towards the notch 13 of the cavity side plate 12. The push block 22 then... The flexible plug 23 blocks the inner end of the side hole 101 of the power panel 100; then, the spray protection device and the power panel 100 are placed together in the working position of the spraying equipment, and the spraying equipment sprays the power panel 100; next, the spray protection device and the power panel 100 are taken out together, the control cylinder 21 is operated, the piston rod of the cylinder 21 retracts inward, driving the push block 22 away from the notch 13 of the cavity side plate 12, and the push block 22 then drives the flexible plug 23 to be released from the inner end of the side hole 101 of the power panel 100; finally, the power panel 100 with the side hole is removed from the spray protection device, and the spraying is completed.

[0020] When the power panel 100 is supported and positioned by the cavity side plate 12, the cylinder 21 can push the flexible plug 23 through the push block 22 to block the inner end of the side hole 101 of the power panel 100. Since the flexible plug 23 can be pushed by the cylinder 21, the flexible plug 23 and the inner end of the side hole 101 of the power panel 100 achieve an interference fit, and the connection is very tight, avoiding gaps. Therefore, after spraying, no burrs will be generated at the inner end of the side hole 101 of the power panel 100, saving the labor cost of burr removal and significantly improving the product spraying quality. This utility model uses a hole-blocking mechanism 2 to block or release the power panel 100. The inner end of the side hole 101 of the power panel 100 does not require the use of high-temperature adhesive tape, saving the labor cost of pasting and tearing off high-temperature adhesive tape, and avoiding the consumption of high-temperature adhesive tape, thus avoiding material waste. The upper end of the cavity side plate 12 of this utility model can support and position the inner edge of the power panel 100, playing a first positioning role. When the flexible plug 23 of the plugging mechanism 2 is pressed against the inner end of the side hole 101 of the power panel 100, it can play a second positioning role. Under the dual positioning role, the problem of large gaps between the protective cavity 1 and the power panel due to shaking, tilting, etc. can be avoided, and the problem of paint entering the interior of the power panel during spraying can be avoided.

[0021] like Figure 3 and Figure 4 As shown, each end of the cavity side plate 12 has a notch 13. There are two hole-blocking mechanisms 2, one of which corresponds to one of the notches 13 and the other corresponds to the other notch 13. By setting two notches 13 and two hole-blocking mechanisms 2, the inner ends of the side holes 101 on both sides of the power panel 100 can be blocked or loosened at the same time.

[0022] like Figure 3 and Figure 4 As shown, in a preferred embodiment of this utility model, the cylinder 21 is a double piston rod cylinder, which has excellent driving stability, and the flexible plug 23 is a silicone plug, which has the best sealing effect.

[0023] like Figure 3 and Figure 4 As shown, in a preferred embodiment of this invention, the shape of the upper end of the cavity side plate 12 matches the shape of the inner edge of the power panel 100. See also Figure 1 The inner edge of the power panel 100 has an annular groove 102, and the upper end of the cavity side plate 12 matches the shape of the annular groove 102 and can be inserted into the annular groove 102.

[0024] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
