Description

Technical Field

[0001] The invention relates to the technical field of corrosion and rust prevention of sheet metal parts, in particular to a device for coating with silver paint. Background Art

[0002] Because various heat generating devices need to be placed in the server cabinet, heat dissipation holes need to be set. The existing conventional practice is to open a heat dissipation space in the corresponding area of ​​the heat generating device. At the same time, in order to ensure the normal assembly of the heat generating device, a heat dissipation space is generally opened in the corresponding area of ​​the heat generating device mounting frame to dissipate heat. The structure of the conventional sheet metal bracket is shown in FIG. Figure 1 , which includes a three-sided structure, in which the upper plate and the lower plate are both provided with a number of heat dissipation grooves formed by discontinuous cutting, which ensure the heat dissipation circulation on the one hand, and ensure the firm installation of the entire sheet metal bracket on the other hand; in actual use, the original anti-rust coating on the cut surface of the cut heat dissipation groove is destroyed. In order to ensure the long-term, effective and reliable use of the entire sheet metal bracket, it is necessary to apply silver paint on the corresponding cut surface of each heat dissipation groove. The existing conventional practices are manual painting and manual spraying, which are generally inefficient, and due to the large number of heat dissipation grooves, it is easy to miss the brushing and spraying phenomenon; in view of this, it is urgent to develop a mechanism that can improve the silver paint coating operation. Summary of the invention

[0008] Oil tank;

[0009] and an oiling module, which includes a bottom plate and a profiling coating head that is shaped according to the shape, number, and position arrangement of the heat dissipation slots, wherein a plurality of coating heads are arranged on the upper surface of the bottom plate in an upward convex arrangement;

[0010] The workpiece placement platform is fixedly connected to the middle crossbeam, the lifting cylinder is fixedly installed on two adjacent columns that are not coplanar with the middle crossbeam, the lower output end of the lifting cylinder is connected to the lifting plate, the horizontal support surface of the lifting plate is located directly below the workpiece placement platform, the bottom plate is fixedly installed on the horizontal support surface of the lifting plate, and the area formed by the combination of several coating heads is located directly below the avoidance gap area;

[0011] The oil tank is arranged above the base, and the upper open surface of the oil tank covers the surface of the bottom plate. The lifting cylinder drives the bottom plate and a plurality of coating heads to be immersed below the oil level of the oil tank to complete the loading of the silver paint. The plate surface of the sheet metal bracket provided with the heat dissipation groove is supported on the workpiece placement platform and is positioned in the plane direction by at least two positioning columns. The lifting cylinder drives the bottom plate and a plurality of coating heads to rise until the outer surfaces of the coating heads respectively penetrate the avoidance notch area and bulge upward to exceed the upper surface of the corresponding heat dissipation groove, and the liquid paint on the outer surface of the coating head is transferred to the cut surface of the corresponding heat dissipation groove.

[0012] It is further characterized by:

[0013] Each coating head comprises an upper guiding profiling part and a lower coating profiling part in the height direction, wherein the lower coating profiling part is retracted by 0.1 mm to 0.2 mm according to the contour of the corresponding heat dissipation slot, and the upper guiding profiling part is retracted from bottom to top within the surface area of ​​the lower coating profiling part, and the upper guiding profiling part is used to guide the insertion into the corresponding heat dissipation slot;

Since the sheet metal bracket has weight, it does not need additional vertical force to ensure the stable and reliable placement of the sheet metal bracket. The lifting cylinder drives the bottom plate together with a number of coating heads to be immersed below the oil surface of the oil tank to complete the loading of the silver paint. After that, the lifting cylinder drives the bottom plate together with a number of coating heads to rise until the outer surfaces of the coating heads respectively penetrate the avoidance notch area and bulge up to exceed the corresponding heat dissipation notch area.

Due to the small number of positioning holes, it will not delay the anti-corrosion operation of the entire sheet metal bracket. It can quickly apply silver paint to the cut surface of each heat sink, ensuring reliable coating and ensuring long-term and reliable anti-rust and anti-corrosion of the sheet metal bracket.

[0035] In specific implementation, the vertical bracket 20 includes a side frame, which is formed by welding two columns 22, an upper crossbeam 24, and a lower crossbeam (blocked in the figure). A base 21 formed by splicing three pipes is welded to the bottom of the side frame, and a top seat 26 formed by splicing three pipes is welded to the top of the side frame. A column 22 for connection is also provided between the top seat 26 and the base 21. The entire vertical bracket 20 has only three columns, which is convenient for having a larger operating space for taking and placing the sheet metal bracket 10. Foot pads 27 are respectively fixed at the four corners of the bottom of the base.

[0041] In specific implementation, the bottom plate 61 is fixed to the upper surface of the horizontal support plate 82 by bolts on all sides, which enables the oiling module 60 to be quickly replaced according to the sheet metal bracket 10 to be oiled, thereby ensuring the versatility of the entire mechanism.

[0042] Its working principle is as follows: the plate surface of the sheet metal bracket with heat dissipation grooves is supported on the workpiece placement platform and is positioned in the plane direction by at least two positioning columns. Since the sheet metal bracket has weight, it does not require additional vertical force to ensure the stable and reliable placement of the sheet metal bracket. The lifting cylinder drives the bottom plate together with a number of coating heads to be immersed below the oil level of the oil tank to complete the loading of the silver paint. Then the lifting cylinder drives the bottom plate together with a number of coating heads to rise until the outer surfaces of the coating heads respectively penetrate the avoidance notch area and bulge up to exceed the corresponding heat dissipation area. The upper surface of the groove is transferred to the cut surface of the corresponding heat dissipation groove through the liquid paint on the outer surface of the coating head. In order to ensure reliable coating, it can be coated twice or three times in succession. Then the sheet metal bracket can be removed and a new sheet metal bracket can be placed. The silver paint coating on the positioning holes of the sheet metal bracket can be arranged manually for subsequent auxiliary coating. Due to the small number of positioning holes, it will not delay the anti-corrosion operation of the entire sheet metal bracket. It can quickly apply silver paint to the cut surface of each heat dissipation groove, ensuring reliable coating and ensuring the long-term and reliable anti-rust and anti-corrosion of the sheet metal bracket.
