Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, and in particular to a jig used for transformer impregnation treatment. Background Art

[0002] Electronic transformers are indispensable components for electronic, communication and household electrical appliances. In today's information age, with the rapid development of the information industry, electronic transformers have achieved even faster development. In the "Pearl River Delta" region in southern my country, foreign-funded, wholly-owned or joint-venture electronic manufacturers mainly engaged in electronic transformers have sprung up like mushrooms after rain. In recent years, there are more and more electronic manufacturers in the "Yangtze River Delta" region.

[0003] In the production of transformers, vacuum impregnation treatment (i.e. oil treatment of transformers) is required. The impregnation tank in transformer oil treatment is used for coil immersion to improve the penetration ability of insulating paint and increase the filling rate, thereby improving the overall mechanical strength, insulation strength, moisture resistance, and mildew resistance of electrical coils. After the coils are immersed in the impregnation tank, they need to be taken out, dried, labeled, or sprayed, and then the finished product is obtained. The existing impregnation jig is a perforated plate with leak holes. The perforated plate is surrounded by walls, and the height of the walls is greater than the height of the coil to ensure that when the jig is placed in the impregnation tank, the oil can submerge the coil to ensure the impregnation effect. After the impregnation treatment, the jig is taken out and dried, and then the coil is poured out. Since the wall has a certain height, the jig needs to be turned over and dumped when the coil is taken out. This operation reduces the continuity of production. Flipping requires one hand to be raised and the other hand to be lowered. Long-term operation will make the shoulder of the hand that needs to be raised sore and weak. This is not only inefficient, but also if you are not careful, the coil will be dumped outside, scratching and bumping the surface of the coil, reducing the yield. When the coil is taken out in this way, the oil in the impregnation tank will also flow out, which causes waste. Summary of the invention

[0004] The present invention is intended to provide a jig for transformer impregnation treatment to solve the problem in the prior art that when taking out the coil, the jig can only be tilted and turned over, which causes the coil to be easily scratched and the oil is also wasted.

[0005] A jig for transformer impregnation treatment in the present scheme includes a substrate, a surrounding wall is provided around the substrate, a handle is provided on the surrounding wall, a plurality of holes are provided on the substrate, a circular baffle is provided in the hole groove, a plurality of small holes are provided on the circular baffle, the side wall of the circular baffle is slidably connected to the inner wall of the hole groove, the bottom of the circular baffle is vertically connected with a push rod, the push rod passes through the bottom of the hole groove and extends to the bottom of the substrate, a base is provided under the substrate, the push rods are connected to the base, the base is a hollow structure, the bottom of the hole groove is provided with an oil drain hole, a plurality of oil inlet holes are provided on the base, the oil drain holes correspond to the oil inlet holes one by one, a hose for oil drainage is connected between the oil drain hole and the oil inlet hole, a control valve is provided on the hose, and the length of the push rod is greater than or equal to the depth of the hole groove.

[0006] Working principle of the present invention:

[0007] The jig for transformer impregnation treatment in the present invention, when used, first put the coil in the hole groove on the substrate in sequence, because the bottom of the hole groove is provided with an oil drain hole, the base is provided with an oil inlet hole, the oil drain hole and the oil inlet hole correspond to each other one by one, and a hose for draining oil is connected between the oil drain hole and the oil inlet hole, and a control valve is provided on the hose, the control valve is closed, and then oil is added to the hole groove, after the coil is soaked, the control valve is opened, and the handle on the surrounding wall is pressed down by hand, because a circular baffle is provided in the hole groove, a plurality of small holes are provided on the circular baffle, and the side wall of the circular baffle is slidably connected with the inner wall of the hole groove, and a push rod is vertically provided at the bottom of the circular baffle, the push rod passes through the bottom of the hole groove and extends to the bottom of the substrate, the length of the push rod is greater than or equal to the depth of the hole groove, and the push rod pushes the circular baffle to move upward along the inner wall of the hole groove until the coil is pushed out of the hole groove, and at the same time, the oil in the hole groove passes through the small holes on the circular baffle and enters the oil drain hole, and at the same time enters the oil inlet hole through the hose and flows into the base.

[0008] Beneficial effects of the present invention:

[0009] When the coil is soaked using the present solution, it is only necessary to close the control valve first, put the coil into the hole groove, and then add oil to the hole groove. After the soaking is completed, open the control valve, hold the handle on the surrounding wall with your hand, and then press the substrate downward, because a circular baffle is provided at the bottom of the hole groove, and a plurality of small holes are provided on the circular baffle, and the side wall of the baffle is slidably connected to the inner wall of the hole groove, and a push rod is vertically connected to the upper part of the circular baffle. As the substrate moves downward, the push rod pushes the circular baffle to move upward, so that the coil in the hole groove can be pushed out of the hole groove, and at the same time, the oil in the hole groove also enters the base through the hose. Compared with the prior art, this method can effectively prevent the coil from tipping over or scratching or bumping the surface of the coil due to falling from a high place, thereby greatly improving the yield of the coil, and the oil in the hole groove can also be recycled.

[0010] Furthermore, the surrounding wall is connected to the base plate in a buckling manner, which makes it very convenient to clean the base plate.

[0011] Furthermore, a sealing layer is provided at the connection between the surrounding wall and the substrate. The oil in the hole groove will inevitably overflow onto the substrate, so it is easy to flow on the substrate. The sealing layer is provided at the connection between the surrounding wall and the substrate to prevent the oil from flowing out as much as possible, effectively avoiding waste.

[0012] Furthermore, the side wall of the base is connected with an oil outlet pipe, and the oil outlet pipe includes at least two. After the oil in the hole groove is discharged into the base, it is necessary to discharge the oil in the base in time and store it. The side wall of the base is connected with an oil outlet pipe, so that the oil in the base can be discharged, and the oil outlet pipe includes at least two, which speeds up the oil discharge rate and greatly improves the work efficiency.
