A film-pressing wheel and film-pressing equipment thereof

Abstract

The invention provides a film-pressing wheel and film-pressing equipment thereof. The film-pressing wheel includes a tube body, a heat source arranged in the tube body, and a rubber surface coated outside the tube body; the tube body includes an outer tube and an inner tube. The outer wall of the inner pipe is provided with a plurality of oil storage tanks, and the plurality of oil storage tanks are evenly distributed on the outer wall of the inner pipe; each oil storage tank is correspondingly provided with an oil filling tank, and the oil filling tank is arranged on the outer wall of the inner tube , one end of the oil filling tank communicates with the oil storage tank, and the other end extends to the end of the inner tube; the inner tube is nested and installed in the outer tube, and the outer wall of the inner tube is close to the inner wall of the outer tube, so that the oil storage tank and the outer tube A closed space for storing heat transfer oil is formed between the inner walls of the tubes, and an oil filling hole for pouring heat transfer oil is formed between the oil filling groove and the inner wall of the outer tube. The film pressing wheel and film pressing equipment provided by the present invention have the characteristics of gentle and uniform heat and high film yield rate.

Description

technical field [0001] The invention relates to the field of electronic processing, in particular to a film pressing wheel and film pressing equipment. Background technique [0002] With the advent of the electronic industry era, the equipment for producing electronic products and manufacturing parts is booming. Laminator is a device that hot-presses a specific PCB (printed circuit board) dry film onto a PCB. The dry film to be pressed is erected on the laminator equipment. Only the pressing wheel is pressed against each other, relying on the pressure and temperature of the pressing wheel to make the dry film closely adhere to the surface of the PCB. [0003] The lamination process requires that the dry film pressed on the surface of the entire PCB board be neat and uniform without any air bubbles or wrinkles. Consistent with the above, the thickness and hardness of the rubber layer of the lamination wheel are appropriate, only the above points can ensure the quality of th...

Problems solved by technology

The design of heat transfer directly by metal will make the heat conduction of the metal uneven, the temperature high and low, and the temperature of the wheel body will be greatly affected by the ambient air, resulting in rapid temperature rise and fall, which will easily cause the thickness of the film to be formed on the plate surface. Wrinkles, small air bubbles and other phenomena, resulting in a high defect rate of the board surface, a waste of cost, and even degumming
