Technical Field

The invention relates to a vacuum tank for vacuum bubble removal, which can be filled quickly, belongs to the field of vacuum equipment (technology), can be used for vacuum bubble removal during encapsulation processing of electrical products or electronic products, and can also be applied to other fields with similar processing purposes or processes.

Background

Some electrical products, electronic products, electromechanical products and the like need to be encapsulated by encapsulating materials such as epoxy resin and the like so as to improve the protection grade, the insulation level, the heat transfer or heat dissipation capability and the like.

The process of potting of these potting members mainly includes three stages of potting material pouring, vacuum bubble discharging and (heating) curing, wherein the purpose of vacuum bubble discharging is to discharge bubbles in the potting material to improve the electrical and heat transfer performance and surface quality. Vacuum bubble removal is generally performed in a vacuum tank, and the higher the vacuum degree, the faster the bubble removal rate.

For mass produced pottings, the vacuum debubbling process becomes complex and inefficient. The reason for this is that in the process, the potting elements need to be filled into the vacuum tank one by one, and the filling process becomes time-consuming and laborious, especially for those potting elements which have small internal pores, are not easy to bubble, and often need to be filled and filled repeatedly, and the filling and vacuum bubble-discharging process becomes more complicated and inefficient. Secondly, for filling convenience, the vacuum tank of the prior art has large dimensions and large openings in all directions, which reduces the structural strength of the vacuum tank, and needs to be improved by increasing the thickness of the material and the like, so the vacuum tank of the prior art is heavy and consumes large steel.

Disclosure of Invention

The invention aims to provide a vacuum tank for vacuum bubble removal, which can be quickly filled, has larger length, smaller cross section and smaller opening, obviously improves the structural strength and can realize high vacuum degree; secondly, set up track, dolly and movable tray in the vacuum tank to improve filling efficiency.

The invention is realized by the following technical scheme: the vacuum tank body adopts a circular tank body structure with large length and small diameter, an opening and a sealing door are arranged at one end of the tank body, an inner track is arranged below the inner part of the tank body, a rail car is arranged on the inner track, a support is arranged on the rail car, a tray is arranged on the support, an outer track is arranged outside the tank body, the outer track can be connected with the inner track when the sealing door is opened, a filling and sealing piece is placed in the tray, the tray is placed on the support, and the rail car can move between the outer track and the inner track through the opening to realize quick filling and taking out of products; a plurality of layers of trays can be placed on the bracket; the tray is movable and can be placed on and taken down from the bracket; after the rail car enters the tank body, the outer rail can be removed, the sealing door can be closed, and the tank body can be sealed; the tank body is provided with a connecting port of a vacuum pump, and the vacuum pump can vacuumize the vacuum tank after the vacuum pump is connected; the tank body is connected with a vacuum meter which displays the vacuum degree in the vacuum tank.

The principle of the invention is as follows: the inner track, the outer track and the rail car are arranged, so that the problem that the large-batch produced pouring and sealing parts are quickly filled in the deep and long tank body is solved; because the inner track, the outer track, the rail car, the bracket and the tray are arranged, a large number of small-sized potting parts can be quickly filled and taken out; after the external track is removed, the sealing door can be closed and sealed, and the vacuum pump can vacuumize the vacuum tank at the moment; the vacuum tank adopting the circular tank body structure with small diameter and large length has high structural strength, can bear negative pressure generated by high vacuum, not only saves steel, but also can realize high vacuum, thereby improving the bubble discharge speed.

The invention has the following beneficial effects: 1. the bubble discharging speed and the filling and removing speed of the filling and sealing piece are improved, so that the production efficiency is greatly improved, and the production cost is reduced; 2. the tank body has high structural strength, and can realize high vacuum so as to improve the bubble discharge speed; 3. the foaming is faster and more thorough under the high vacuum condition, and the product quality can be obviously improved; 4. the tank body has high structural strength and can be manufactured by adopting finished pipes, so that the manufacturing cost of the vacuum tank is greatly reduced.
