The application takes the PFC module applied to a small manual welding welder as an example for explanation.

A common PFC module assembly method is manual assembly with cooperation of multiple persons, generally more than 9 persons are needed to cooperate with one PFC module at the same time, and the manual correction process is time-consuming, resulting in high labor cost and low efficiency.

In the prior art, a PFC module is formed by modularizing a PFC template, and the PFC module includes a module housing and a cover, wherein the cover is provided with a mounting hole for a guide post to pass through, and the cover is divided into a flat plate and a sliding plate, and the flat plate is in insertion fit with the sliding plate. During work, an operator sets the device on the sealing cover, and the PFC module is fixed through sliding connection of the sealing cover and the shell. However, the PFC module has problems of complex structure and high processing cost.

In order to solve the above problem, referring to fig. 1 and 2, the present embodiment provides a PFC module. The PFC module includes a component 100, a limiting plate 200, and a mounting plate 300. Wherein, limiting hole 210 has been seted up on the limiting plate 200, and this limiting hole 210 can hold components and parts 100, and this limiting hole 210 can restrict the position of placing of components and parts 100, and mounting panel 300 is connected with limiting plate 200, and mounting panel 300 is used for installing components and parts 100.

The PFC module optimizes the manual positioning process, saves the installation time, is beneficial to improving the installation efficiency of the installation plate 300 and the component 100, and has a simple structure and convenient processing, thereby realizing the reduction of the processing cost. Specifically, the number of the limiting holes 210 may be 1 or more, and is not particularly limited in the present application, depending on the number of the components 100 to be mounted on the mounting board 300. The mounting board 300 is preferably a PCB board, which can provide stable support for the connection of the components 100, and is a conventional component and is widely used in the field of electronic circuits.

As an alternative, referring to fig. 2, the PFC module further includes a heat dissipation member 400, the heat dissipation member 400 is connected to the limiting plate 200, and the heat dissipation member 400 can dissipate heat for the component 100, so as to prevent the temperature of the component 100 from rising during the operation process to affect the operation effect. Meanwhile, the long-term operation of the component 100 at a high temperature will result in a reduced lifetime, and the heat generated by the component 100 is absorbed in time by the heat sink 400, which is beneficial to improving the service life of the component 100.

Referring to fig. 2, in order to improve the heat dissipation effect of the heat dissipation member 400, the PFC module further includes a fan 600, the fan 600 is disposed at one side of the heat dissipation member 400, and the fan 600 can extract the heat collected by the heat dissipation member 400 and conduct the heat to the outside, so that the heat absorbed by the heat dissipation member 400 from the component 100 is quickly dissipated, thereby being beneficial to ensuring the heat dissipation effect of the heat dissipation member 400.

As shown in fig. 2, the PFC module further includes a bracket 500, and the heat sink 400 and the fan 600 are disposed on the bracket 500, so that the heat sink 400, the fan 600, the bracket 500, the limiting plate 200 disposed on the heat sink 400, and the mounting plate 300 form an integral module, which is convenient for an operator to mount and maintain, and is beneficial to expanding the application range of the PFC module.

The detailed structure of the stopper plate 200 will now be described with reference to fig. 3.

Referring to fig. 3, as an alternative, the position limiting member includes a position limiting plate body 230 and a plurality of supporting columns 260, the plurality of supporting columns 260 are disposed on the position limiting plate body 230, and the plurality of supporting columns 260 can support the mounting plate 300. Meanwhile, a third mounting hole 261 is formed in the center of each supporting column 260, and a fourth mounting hole is formed in the positions of the mounting plate 300 and the third mounting hole 261, the PFC module further comprises a fixing piece, the fixing piece can penetrate through the third mounting hole 261 and the fourth mounting hole, and the mounting plate 300 and the limiting plate 200 are fixed on the radiating piece 400, so that the mounting plate 300 and the limiting plate 200 are fixedly mounted, and the situation that the positions of the mounting plate 300 and the limiting plate 200 are moved to influence the stability of the PFC module in the working process of the welding machine is avoided.

As shown in fig. 3, since the mounting plate 300 has limited strength and the four corners of the mounting plate 300 are supported by the supporting columns 260, the limiting plate 200 includes the supporting portions 220 to prevent the mounting plate 300 from being damaged due to the middle collapse. The supporting portion 220 and the limiting hole 210 are correspondingly arranged, and the supporting portion 220 can support the mounting plate 300, so that the stability of the PFC module is prevented from being influenced by the collapse of the middle position of the mounting plate 300. Specifically, in order to improve the supporting effect of the supporting portion 220, the supporting portion 220 may be correspondingly disposed at each position of the limiting hole 210, so as to realize multi-point support of the mounting plate 300, and further improve the stability of the PFC module in the working process.

Installation department 240 is the L type setting with limiting plate body 230, and installation department 240 can carry on spacingly for limiting plate body 230 along the position of X direction to be favorable to improving limiting plate 200's installation effectiveness. Specifically, when the position limiting plate 200 is mounted, the mounting portion 240 may first abut against the side surface of the heat sink 400, and the position of the position limiting plate 200 in the X direction may be restricted, and the operator only needs to slide in the Y direction with the mounting portion 240 abutting against the side surface of the heat sink 400 as a reference, so that the third mounting hole 261 of the support pillar 260 is more easily aligned with the corresponding hole in the heat sink 400, and the mounting efficiency is greatly improved. Meanwhile, the structural design of the mounting part 240 is also beneficial to reducing the number of mounting personnel of the PFC module, and the purpose of saving labor cost is achieved.

As shown in fig. 3, further, a third mounting hole 261 is formed in the mounting portion 240, and after the position of the mounting portion 240 is fixed, the mounting portion 240 is fixed to the heat sink 400 by a fixing member, so that the limiting plate 200 is prevented from moving in the working process of the PFC module, and the stability of the PFC module is further improved.

As shown in fig. 3, specifically, the limiting plate 200 further includes a reinforcing rib 250, and the reinforcing rib 250 is disposed on the mounting portion 240 in an extending manner along the Z direction, so that the strength of the mounting portion 240 is improved, and the stability of the connecting of the limiting plate 200 and the heat sink 400 is enhanced. More preferably, the reinforcing ribs 250 extend from a surface perpendicular to the mounting portion 240 to a direction away from the mounting portion 240, and the height of the reinforcing ribs 250 increases in order from bottom to top in the Z direction, so that the reinforcing ribs 250 can play a role in guiding. It is understood that, when the heat sink 400 is mounted to the bracket 500 after the position limiting plate 200 is mounted to the heat sink 400, and the heat sink 400 is aligned at the inlet of the mounting position of the bracket 500, the height of the reinforcing ribs 250 is small, so that the heat sink 400 can be easily placed in the inlet. As the heat sink 400 is placed downward in the Z direction, the height of the reinforcing ribs 250 gradually increases, so that the position of the heat sink 400 gradually approaches the preset position, thereby achieving the guiding function of the reinforcing ribs 250.

Preferably, in order to improve the production efficiency of the limit plate 200, the limit plate 200 is integrally formed by a mold, so that the processing cost of the PFC module can also be reduced.

The detailed structure of the mounting board 300 and the component 100 will now be described with reference to fig. 4.

The specific working process of this embodiment is as follows:

as shown in fig. 2 and 3, an operator can correspondingly place the positions of the limiting plate 200 and the component 100 on the heat dissipating member 400, and then abut against the heat dissipating member 400 through the mounting portion 240, so as to limit the X direction of the limiting plate 200, move the limiting plate 200 along the Y direction, align the third mounting hole 261 on the limiting plate 200 with the corresponding hole on the heat dissipating member 400, and then pass the guiding column 110 through the first mounting hole 121 to mount the corresponding positions of the mounting plate 300 and the limiting plate 200, so that the operator fixes the mounting plate 300, the component 100, the limiting plate 200 and the heat dissipating member 400 through the fixing member, thereby realizing the rapid mounting of the PFC module.
