[0002] A hot press is a device that heats two pre-tinned parts with flux to a temperature high enough to melt and flow the solder. After solidification, a permanent electrical and mechanical connection is formed between the parts and the solder. The heating rate can be selected according to different products. The titanium alloy pressure head ensures uniform temperature, rapid heating and long service life. In the manufacturing process of circuit boards, hot pressing is an indispensable process link. Circuit board molding requires placing the module circuit board in a hot press. Under high temperature and high pressure, pressure is used to firmly connect the circuit board and the copper busbar. Hot pressing has the advantages of firm connection and good conductivity. Most existing hot presses require manual placement of the circuit board on the bottom plate for hot pressing when in use.

[0003] At present, the existing flexible circuit board hot pressing binding equipment, when the temperature is low in winter, coupled with the cold temperature of the workpiece itself, requires a long period of heating to reach the temperature requirements for hot pressing binding of the circuit board.

At this time, the staff places the circuit board on the guide assembly and pushes it to one side of the operating table, so that the circuit board slides and moves on the surface of the guide assembly to guide and transport the circuit board. The circuit board passes above the operating table, and then the staff starts the hot pressing assembly, so that the hot pressing assembly descends and hot presses the flexible circuit board above the operating table, so that the adhesive between the circuit board and the copper bus is melted by heat to bond the circuit board and the copper bus.

[0010] Preferably, the guide assembly includes a bottom support frame, the bottom support frame is fixedly installed between the opposite surfaces of the side frames, and the top two sides of the bottom support frame are fixedly installed with a clamping plate, and the inside of the clamping plate is clamped with a stabilizing member, and the stabilizing member is provided with two groups, and the inside of the two groups of stabilizing members are both rotatably installed with conveying rollers.

Under high temperature and high pressure environment, pressure is used to firmly connect the circuit board and the copper busbar. The circuit board is placed on the bottom plate for hot pressing. At this time, the staff places the circuit board on the guide assembly and pushes it to one side of the operating table, so that the circuit board slides on the surface of the guide assembly to guide and transport the circuit board.
