Technical Field
[0001] The utility model relates to the field of electronic components, and more specifically to a side coating jig. Background Art
[0002] Surge protection devices (SPDs) are used to absorb lightning overvoltage spike pulses, filter out interference signals in the power grid, and protect system safety. They have been widely used in precision and expensive instruments, equipment, and power supply systems in military, new energy, communication base stations, railways, meteorology, and other systems to protect instruments and equipment from lightning strikes and other transient overvoltage interference. As the application of SPDs becomes more and more extensive, the application environment has become more complex, especially under high temperature and high humidity conditions. The core component of SPD, the lightning valve MOV (Metal Oxide Varistors), is a resistor device with nonlinear volt-ampere characteristics based on zinc oxide.

[0030] The following combination Figure 1 to Figure 6 Taking the side coating jig provided by the embodiment of the utility model as an example, the side coating jig is described in detail.
[0031] like Figure 1 As shown, the side coating jig provided by the embodiment of the utility model mainly includes: a bracket body 13, a fixing rib assembly, a hole 12, a limiting groove 11 and the like.
[0032] Specifically, the bracket body 13 is used to set the lightning protection valve plate. Fixed ribs are set around the bracket body 13, and four fixed ribs distributed around the bracket body 13 constitute a fixed rib assembly. In order to fix the bracket body 13 on the fixed rib, preferably, a limiting groove 11 is set on the side of the fixed rib close to the bracket body 13, and the width of the limiting groove 11 is equal to the thickness of the bracket body 13. The limiting groove 11 can effectively fix the fixed rib on the bracket body 13 to prevent sliding and loosening due to long-term use; further, a plurality of holes 12 are also set on the fixed rib, and the fixed rib is fixed to the bracket body 13 by screwing the bolt 4 into the hole 12 set on the fixed rib and tightening it.
[0033] The fixing ribs provided in the embodiment of the utility model are made of aviation aluminum material, which can not only reduce the deformation of the bracket body 13 after repeated use, but also increase the strength of the side coating fixture, which is beneficial to the track clamping operation.
[0034] For example, in the side coating jig provided by the embodiment of the utility model, the shape of the bracket body 13 is rectangular, and the fixing ribs located on the long side of the bracket body 13 are respectively the first fixing rib 21 and the second fixing rib 22; the fixing ribs located on the wide side of the bracket body 13 are respectively the third fixing rib 31 and the fourth fixing rib 32; further, 5 holes 12 are evenly arranged on the first fixing rib 21 and the second fixing rib 22, and 3 holes 12 are evenly arranged on the third fixing rib 31 and the fourth fixing rib 32. The first fixing rib 21, the second fixing rib 22, the third fixing rib 31 and the fourth fixing rib 32 are symmetrically arranged on the bracket body 13, and are screwed into the holes 12 by sixteen hexagon socket bolts 4 to be tightened and fixed.
[0035] For example, the side coating jig provided by the embodiment of the utility model further includes positioning grooves, and a plurality of positioning grooves are evenly arranged on the bracket body 13 in a matrix arrangement, and the positioning grooves are used to set the lightning protection valve sheet. The positioning grooves can prevent the lightning protection valve sheet from sliding sideways and shifting during track operation, and avoid the suction cup from grabbing the lightning protection valve sheet without being in the center, resulting in uneven thickness of the side coating on all sides, and in severe cases, the insulating material may not be coated.
[0036] It should be noted that, in practical applications, the shape of the lightning protection valve plate includes a circle and a rectangle, the radius of the circle can include a variety of numbers, and the length and width of the rectangle can include a variety of sizes. Figure 2As shown, the specifications of the lightning protection valve plate can include a first specification 5, a second specification 6, a third specification 7, a fourth specification 8 and a fifth specification 9, wherein the first specification 5 is circular and the other specifications are all matrices. The positioning groove provided by the embodiment of the utility model includes a multi-specification sleeve design, which can not only improve the utilization rate of the fixture, but also effectively reduce the production cost.
[0037] Furthermore, exhaust holes 10 are provided on the bracket body 13, and the number of the exhaust holes 10 is consistent with the number of the positioning grooves provided on the bracket body 13, and the exhaust holes 10 are concentrically arranged with the positioning grooves. This arrangement not only facilitates the stacking of lightning protection valve sheets, but also facilitates the grasping of the suction cup, thereby avoiding the difficulty in suction caused by the pressure difference.
[0038] In actual application, the six suction cups of the lightning protection valve sheet insulation layer side coating device automatically absorb the lightning protection valve sheet stacked in the positioning groove on the bracket body and move it to the bottom of the brush pen under the action of the predetermined program. The six suction cups rotate one to two weeks at the same time, and the tightly sucked lightning protection valve sheet also rotates one to two weeks. The other end of the brush pen is equipped with a paint bucket, and the pressure is used to continuously supply the brushed insulating material to the brush pen to ensure the continuity and consistency of the brushing. The distance between the lightning protection valve sheet and the brush pen can control the brushing thickness. After the brushing is completed, the lightning protection valve sheet is also transported to the predetermined position of the curing furnace by the suction cup through the program for curing. At this point, the whole process is completed. This method has low production cost and high efficiency, and has good brushing thickness, continuity and consistency of the insulating coating.
[0039] The embodiment of the utility model provides a side coating jig, including: a bracket body, which is used to set a lightning protection valve sheet; a fixed rib assembly, which includes four fixed ribs, and the four fixed ribs are symmetrically arranged around the bracket body; a hole, which is arranged on the fixed rib, and the bolt fixes the bracket body through the hole; a limit groove, which is located on the side of the fixed rib close to the bracket body, and the width of the limit groove is equal to the thickness of the bracket body. The coating test jig provided by the embodiment of the utility model has fixed ribs arranged around the bracket body, which, on the one hand, reduces the deformation of the bracket body for repeated use, and on the other hand, increases the strength of the coating test jig, which is conducive to track clamping operation. Moreover, by arranging holes and limit grooves on the fixed ribs, the bracket body can be effectively fixed on the fixed ribs to prevent sliding and loosening during long-term use; further, the positioning groove is arranged on the bracket body, which can prevent the lightning protection valve sheet from sliding and displacement during track operation, and avoid the suction cup from not being in the center of the valve sheet when grabbing, resulting in uneven thickness of the side coating around, and in severe cases, the insulating material may not be coated. When a high-resistance moisture-proof layer is applied to the side of a lightning protection valve plate by means of the side coating jig, the production cost is reduced while the production efficiency is improved, and the coating thickness, continuity and consistency of the insulating coating are good.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
