Design of a Modular Hot Plate Welding Unit
Author:
We often hear customers complain: "we only need to weld such small parts, why do we sell me such a large equipment, the price is too expensive", "can your equipment sell welded parts to me, the peripheral frame is too big I don't want, so I am here to facilitate automatic integration". We will patiently explain the customer's complaints, but the result is still "no".
Including common hot plate/infrared welding equipment, laser welding equipment and ultrasonic welding equipment, there are such problems. Today, let's take a look at how Extol provides unexpected products to customers through modular design.
One of Extol's main products is servo hot plate welding equipment, suitable for welding large tanks and components. If the pipe fittings, brackets and cover plates on automobile parts are to be welded, the maximum size of such parts is often less than 100mm, which is "overqualified" and "expensive".
Hot plate welding is the process of melting and connecting two plastic welding ribs together with a heating plate. First, the welding ribs of the upper and lower plastic parts are in contact with the heating plate. The heat of the hot plate is conducted to the weld bars to melt them. Then, remove the heating plate and press the upper and lower pieces tightly until they are firmly connected to each other.
Customer's challenge: Using standard hot plate welding equipment, several small parts are welded to a main body part. Typical parts are manifolds in the engine compartment of an automobile. Many different brackets are welded to the long and tortuous main body. If the use of multiple standard equipment, is undoubtedly expensive. For this reason, Extol's engineers have developed a modular hot plate welding unit with a light and compact design that is very convenient to install on the automation line. Economy and flexibility to meet customer requirements.
The working principle of EXTOL modular hot plate welding unit: the lower mold can fix larger parts. The higher upper die is moved up and down by servo or electric cylinder control. The heating plate on one side is moved up and down by the cylinder. During the welding process, the part placed on the upper mold presses the hot plate, and the hot plate is pushed together to press the part on the lower mold. Once melting is complete, the upper mold is retracted and the heating plate is retracted. Finally, the upper mold presses the part down to the part on the lower mold and welds the two together.
