Description

Technical Field

[0001] The invention relates to the technical field of glazing of zinc oxide resistors, in particular to automatic glazing equipment for zinc oxide resistors. Background Art

[0002] During the production process of zinc oxide resistors, an insulating glaze needs to be rolled on the surface of the resistor to provide external insulation and prevent breakdown. However, due to the diversity of material components (such as resistor raw materials, inorganic insulating layers and organic insulating glazes), when the resistor is subjected to millisecond square waves or microsecond high current shocks, the rapid change in heat may cause stress in each part due to differences in thermal expansion and contraction coefficients. Under this long-term effect, if the thickness of the coating is not accurately controlled, cracking and peeling will occur, thereby affecting the performance of the resistor and related products. The traditional process uses manual labor to place each piece on a roller coating machine, and then remove the resistor after a certain period of rolling, which is time-consuming and labor-intensive. At the same time, it is easy to cause inconsistent coating thickness, with problems such as being too thick, too thin or uneven, thereby affecting the electrical properties of the resistor. For this reason, an automatic glazing device for zinc oxide resistors is proposed to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0015] like Figure 1-14As shown, the present invention provides an automatic glazing device for zinc oxide resistors, including a rack 1. The rack 1 is made of aluminum alloy, which has low density and light weight, and can reduce the overall weight of the rack of the automation equipment; at the same time, the aluminum alloy has good strength. Through appropriate alloying and processing technology, its strength can meet the requirements of most automation equipment racks; the aluminum alloy also has good corrosion resistance and can form a dense oxide film in the air to prevent further oxidation; a support plate 14 is fixed above both sides of the rack 1, and the support plate 14 has a plurality of first bearing holes 13 for installing the first bearing 12, and a first shaft rod 16 is used to fix it in the first bearing 12 on both sides, and the first shaft rod 16 is fixedly connected to the second single-row sprocket 15 and the chain 2 The chain 2 cooperates with each other to rotate, a fixing plate 21 is fixed on the chain 2, a fixing column 22 is provided on the fixing plate 21, and the cross section of the fixing column 22 is an isosceles trapezoid, so that the resistor 23 can be inserted into the fixing column 22 without shaking and falling due to the transmission of the chain 2; in order to prevent the resistor from being eroded by external environmental factors, such as humid air, corrosive chemicals, etc., in some environments with high humidity, if the resistor 23 is not protected by glaze spraying, the metal material on its surface may undergo oxidation reaction, resulting in changes in resistance value, and glaze spraying can effectively isolate air and moisture to maintain the stability of the resistor performance; the resistor 23 is driven into the glaze spraying device 5 with the chain 2, and the resistor 23 is moved in the glaze spraying device 5 by controlling the speed of the chain 2 The length of the glaze spraying time controls the thickness of the glaze to improve the qualified rate of the product; the connection port of the glaze spraying device 5 is fixedly connected to the upper and lower sides of the support plate 14, and a plurality of connection holes are provided on the upper and lower sides of the glaze spraying device 5 for installing a glaze spraying gun 27. The resistor 23 is driven by the chain 2 to evenly spray the glaze on the surface of the resistor 23 with a certain pressure and speed, so that the glaze can be completely attached to the surface; during the spraying process, it is necessary to control the flow rate of the glaze, the spraying distance and the speed and other parameters, which will directly affect the thickness and quality of the glaze layer; the resistor 23 after coming out of the glaze spraying device 5 passes through the cooling box 4 so that the glaze is quickly condensed and fixed on the resistor, and the cooling box 4 is provided with a plurality of through holes 28, and the through holes 28 are connected to the cooling fan 3 0, and fasteners 29 are used to pass through the through holes 28 and connect with the fixing holes 31 to fix the cooling fan 30 in the cooling box body 4; the resistor sheet 23 coming out of the cooling box body 4 passes through the material taking plate 32 arranged below the fixing column 22, and an inclined plate 33 is fixed on the material taking plate 32. Since the cross section of the fixing column 22 is an isosceles trapezoid, the resistor sheet 23 will not be too much inserted into the fixing column 22 and contact the fixing sheet 21. The inclined plate 33 and the fixing sheet 21 are in a relatively inclined position, and the top of the inclined plate 33 does not contact the fixing sheet 21.

The first roller 38 and the second roller 39 rotate in coordination with the belt 35, and the resistor 23 that falls off the fixed column 22 falls on the belt 35. The material receiving plate 46 is fixedly connected below the connecting plate 34, and a material receiving box 6 is provided below the other side of the material receiving plate 46.
