1、 Basic working principle of dual station pulse hot press machine

The pulse hot press machine effectively loads a certain pulse voltage on its heating head to a certain extent. During operation, the hot press head heats up, effectively raising the temperature of the connected objects. When the temperature reaches the melting point of the solder (i.e., the pre-set temperature) during operation, the tin between the connected objects is melted and connected together

The pulse current of the hot press machine during operation refers to the ratio of the ON and OFF frequency of the current. The larger the pulse ratio, the greater the current output, and the faster the temperature rise of the welded joint.

Product features of dual station automatic hot press machine

1) PLC control system, constant temperature heating method, high-precision temperature control module, accurate temperature control.

2) The hot melt adhesive process adopts a dual head working method, with one head hot pressed and the other head cold pressed, to achieve the best hot melt bonding effect.

3) The hot melt process for nuts uses a hot pressing head with two strokes to heat the nut before embedding it.

4) The equipment can be used as a platform for inbound and outbound, left-right mobile feeding, and automatic feeding for hot and cold pressing, improving efficiency.

5) The dual button start switch, emergency stop protection device, over temperature alarm and other functions ensure production safety.

Advantages of pulse hot press machine

Pulse hot press machines are mainly used to a certain extent for welding devices that cannot be welded using normal SMT+reflow ovens. When welding with a soldering iron, it is very easy to encounter inconsistent and uneven welding appearance, virtual soldering, and product damage.

A pulse hot press machine is different from a constant temperature soldering iron. The pulse hot press machine can reach the desired temperature at the moment of power on, and once no voltage is applied to the two ends of the soldering head, it can instantly reach room temperature. Moreover, the soldering head is flat, so the appearance of the welded product is flat and consistent, with very few virtual soldering defects.

The pulse hot press machine can effectively place its workpiece in the fixture to a certain extent, so that the fixture can be sent under the welding head. When operating, the double start button can be effectively pressed. During operation, the welding head presses against the workpiece, and the temperature rises rapidly and accurately according to the input parameters during use, up to 4 temperature zones (solder reflow at this time), blowing air for cooling (solder solidification), and the welding head rises (completed).

Pulse hot press machine can effectively load a certain pulse voltage on the hot press head. When in use, the voltage head heats up, and the connected objects can be heated up. When the temperature reaches the melting point of the solder (i.e., the pre-set temperature), the tin between the connected objects is melted and connected together The general pulse hot press uses temperature closed-loop control.
