Abstract

The invention relates to an insert block type thermal compression welding device with high welding speed and good welding effect and a thermal compression welding method. The thermal compression welding device comprises a power unit and a control unit. When being used, the thermal compression welding device is electrified, an upper roll embossing block for welding and a lower roll embossing block for welding are heated to the set welding temperature to ensure that the temperature of the upper roll embossing block for welding is a little higher than that of the lower roll embossing block for welding; a preheating block is heated to the set preheating temperature, then an oil cylinder falls, the welding material is covered on the lower roll to form a certain wrap angle and passes through a welding region with the upper roll and the lower roll at the same linear speed; in the welding process, a thermocouple is used to detect the temperature, if the temperature is higher than the required temperature, the control unit stops heating the electric heating tube on the tooth part of the welding place; if the temperature is lower than the welding temperature, temperature compensation is performed; the thermocouple can also detect whether the electric heating tube is burnt out or not; if the gap to be welded is too large or small, a wedge block component is used for adjustment; and when the thermal compression welding device is stopped, the oil cylinder moves upward, the material leaves the lower roll for preventing burning.
