How does the hot plate machine operate the control system?
1. The hot plate machine adopts programmable controller (PLC) and touch screen to control the whole operation process, which can be fully automatic operation or manual operation. The following points: 2. Each end of the equipment shall be equipped with double emergency stop buttons, switch buttons and alarm devices. 3. The parameter setting interface is locked with a password to prevent unauthorized personnel from modifying and setting parameters. 4. The status indicator is set on the control panel, and various states of the machine can be displayed on the control panel. 5, equipped with an independent distribution box, circuit function block, strong current, weak current partition control, in the equipment maintenance, at a glance, in order to facilitate maintenance. 6. Electric control cabinet (integrated with machine) 7. Programmable controller, installed in the electric control cabinet 8. The gas path adopts integrated gas path module, which is neat and clear, beautiful and generous 9. Button operation panel 10. Various parameters can be input for equipment operation (hot melt time, curing time, heating temperature, etc.) 11. Installed on the left side of the operator 12. All functions can be operated on the operation panel: debugging (manual), automatic welding and parameter setting.

(I) on Laser Welding Technology of Plastics
New technologies provide practical operability for the development of many new products, such as biopharmaceutical chips, which are mostly composed of plastic sheets. There are many on the plastic sheet μ The structure of the m limit requires the use of plastic laser precision welding technology during packaging.

Design of a Modular Hot Plate Welding Unit
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 (Figure 1), which is 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.
