Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to an automatic assembly device for the beading of switching power supplies. Background technique [0002] Switching power supply, also known as switching power supply and switching converter, is a high-frequency power conversion device and a type of power supply. like Figure 10 and Figure 11 As shown, the bead is one of the important parts in the switching power supply, and the function of the bead is to compress other parts through the threaded hole on the bead with the screw. However, since the bead itself is not made of insulating material, it is necessary to cover the bead with a heat-shrinkable insulating sleeve for insulation, otherwise the bead may cause the switching power supply to fail due to conduction. The traditional method of assembling the heat-shrinkable insulating sleeve on the bead is manual assembly, such as Figure 12 As shown in the figure, manually...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the efficiency of manually assembling the heat-shrinkable insulating sleeve on the bead is relatively slow and cannot meet the existing production requirements, the present invention provides an automatic assembly of the bead of a switching power supply The equipment uses a stepping motor to drive the turntable to perform step-by-step rotation. During the rotation process, the heat-shrinkable insulating sleeve can be automatically assembled to the bead through the bead feeding device, the heat-shrinkable insulating sleeve feeding device, and the sleeve propulsion device. On the other hand, the perforation and blanking device can not only perforate the heat-shrinkable insulating sleeve on the briquette, but also feed the perforated briquette to the heat-shrinking mechanism, and the heat-shrinking mechanism can heat the briquette to make it The heat-shrinkable insulating sleeve can wrap the bead, and the invention has a high degree of automation, which greatly improves the assembly efficiency of the bead
