Description

Technical Field

[0001] The utility model relates to a disassembling device for defective plastic welding products. Background Art

[0002] Plastic ultrasonic welding is an efficient thermoplastic plastic connection technology. It melts the plastic surface through the friction heat generated by high-frequency vibration, and realizes the rapid welding of two plastic parts. Although ultrasonic welding technology has many advantages, it still has some shortcomings in practical applications, especially for products with other parts inside the plastic parts. When there are problems such as loose welding, surface damage or internal stress, and insufficient waterproofing at the weld, it is necessary to disassemble the welded plastic parts to facilitate the recycling of plastic parts and the recycling of internal usable parts. However, the disassembly of poorly welded injection molded products currently requires manual repeated knocking and breaking of the injection molded products, which is tiring and time-consuming, and it is also easy to damage the internal components.

[0008] Furthermore, a positioning block is included, which is arranged on one of the clamping members.

[0009] Furthermore, the clamping member is provided with a clamping groove adapted to the shape of the plastic member to be removed.

[0010] Furthermore, a third seat body is included, which is adjustably arranged on the second seat body along the axial direction of the slide rail; the quick clamp is arranged on the third seat body.

[0011] Furthermore, a sensor is included for stopping the operation of the welding head.

[0012] Furthermore, the sensor is a safety light barrier.

[0013] Furthermore, the working portion of the welding head is V-shaped.

[0014] Furthermore, the buffer mechanism includes a spring and / or an oil pressure buffer, which acts on the clamping assembly along the axial direction of the slide rail.
