Precision plastic welding equipment

Abstract

The invention provides precision plastic welding equipment which is used for welding a first plastic piece to a second plastic piece. The precision plastic welding equipment comprises a hot melting device, a conveying device, a driving device and a fixing support, the hot melting device is provided with a first hot melting end in contact with the first plastic piece and a second hot melting end incontact with the second plastic piece, and the conveying device picks up a first welding piece; and the driving device comprises a hot melting driver used for driving the hot melting device, the hotmelting driver comprises a connecting plate connected with the hot melting device, a sliding block installed on the connecting plate and provided with a perforated hole, a rotating shaft in through connection fit with the perforated hole and a servo driving machine for driving the rotating shaft to rotate, an internal thread is arranged on the perforated hole, and the rotating shaft is provided with an external thread in threaded fit with the internal thread; and the fixing support is used for fixed installation of the driving device. By means of the precision plastic welding equipment, the condition of too deep heating or insufficient heating depth of the first hot melting end on the first plastic piece can be avoided, and the condition of too deep heating or insufficient heating depth ofthe second hot melting end on the second plastic piece can be avoided.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to a precision plastic welding equipment. Background technique [0002] The plastic welding machine mainly welds plastic parts through a welding assembly controlled by temperature, which includes a heating plate for welding plastic parts. Its working principle is that during welding, the heating plate is placed between the first plastic part and the second plastic part. When the first plastic part and the second plastic part are respectively close to the heating plate, the first plastic part and the heating plate will The plastic at the contact position starts to be heated and melted, and the plastic at the position where the second plastic part is in contact with the heating plate begins to be heated and melted. After a preset heating time has elapsed, the plastics on the surface of the first plastic part and the second plastic part will respectively reach a certain degree of mel...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of precision plastic welding equipment, aiming at solving the problem of low movement precision of the driving mechanism in the prior art, which may easily cause the heating depth of the heating plate to the first plastic part to be insufficient or too deep, and the heating plate to the first plastic part to be heated too deeply. 2. The heating depth of the plastic parts is not enough or the heating is too deep, resulting in poor product quality technical problems
