Abstract

The utility model discloses an automatic pressing device for UV (Ultra Violet) curing of a miniature transformer. The automatic pressing device comprises a base, an air cylinder, a guide post, a guide plate, two support plates, two pressing plates and a track, wherein the guide plate is arranged at the upper part of the guide post in a sleeving manner and is matched with the guide post in a sliding manner; the air cylinder is installed on the base, and the piston rod of the air cylinder is connected with the guide plate; the two pressing plates are fixedly arranged on the top surfaces of the two support plates respectively and are parallel to each other, and ribs are arranged on the inner side edges of the lower surfaces of the two pressing plates; and the two ribs are respectively positioned over two sides of the track groove of the track. When the miniature transformer is subjected to UV curing, the automatic pressing device is adopted to enable a frame and a magnetic core to be closely fitted and ensure that the frame is in a horizontal state in the magnetic core.

Description

Miniature transformer UV solidifies automatic pressing device

Technical field

The utility model relates to the production and processing device of miniature transformer, and the UV that is specifically related to a kind of miniature transformer solidifies automatic pressing device.

Background technology

Miniature transformer is widely used in each class of electronic devices, as shown in Figure 6, miniature transformer comprises skeleton 10 and magnetic core 9, be provided with cylinder 11 and stitch 12 in the both sides of skeleton, by locate some UV glue in the slit of skeleton and magnetic core, skeleton and magnetic core are fastened as a whole, and wherein UV is that ultraviolet is ultraviolet abbreviation.Because UV glue is a kind of adhesive that needs the ultraviolet ray irradiation to solidify, therefore after miniature transformer is carried out a glue, needing again transformer to be carried out the ultraviolet ray irradiation solidifies, and when transformer being carried out ultraviolet ray irradiation curing, for skeleton and magnetic core are fitted tightly, guarantee that skeleton is the level of state in magnetic core, just need to apply external force to skeleton, skeleton is the level of state in magnetic core.

The pressing mode of taking during existing transformer UV solidifies is that the miniature transformer behind a plurality of somes glue is positioned on the smooth aluminium sheet, stitch one side of transformer up, by transparency glass plate of artificial placement, this glass plate is pressed in skeleton and magnetic core is fitted tightly again.There is following problem in this kind pressing mode: 1. since clear glass board plane impetus on stitch, and stitch may have a small amount of distortion behind the high temperature wicking, so that stitch just differs, so transparency glass plate is pressed on the described stitch, can not guarantee that skeleton is in level, produce hidden danger of quality.2. the workman need manually move glass plate, and labour intensity is large, production efficiency is low.

Summary of the invention

The purpose of this utility model is to provide a kind of miniature transformer UV to solidify automatic pressing device, when miniature transformer carries out UV curing, skeleton and magnetic core is fitted tightly, and guarantees that skeleton is the level of state in magnetic core.

Miniature transformer UV described in the utility model solidifies automatic pressing device, comprise pedestal, cylinder, lead, guide plate, two supporting brackets, two block pressur plates and track, lead is vertically fixed on the pedestal, guide plate is sleeved on lead top and lead is slidingly matched, cylinder is installed on the pedestal, its piston rod is connected with guide plate, two supporting brackets are parallel be fixed on the guide plate vertical with guide plate, track is between two supporting brackets, simultaneously parallel with two supporting brackets and guide plate, two block pressur plates are separately fixed at two support plate top surface and are parallel to each other, place, the inside edge of two block pressur plate lower surfaces is provided with fin, two fins lay respectively at track the rail groove both sides directly over.

Rail supported in this device is suspended between two supporting brackets in this device the below of two block pressur plates on other device.

The course of work of this device is as follows:

1. the miniature transformer behind many some glue moves to the pressing plate below by track one end, the projection of skeleton both sides lay respectively at fin on the pressing plate under.

2. cylinder moves down by the pressing plate that guide plate drives on the supporting bracket, and the fin that pressing plate lower surface inside edge is located is pushed down the cylinder of miniature transformer skeleton both sides, and transformer is pressed in orbit.

3. after miniature transformer being carried out UV curing, cylinder rises by guide plate band dynamic pressure plate, and the miniature transformer after the curing is shifted out by the track other end.

When miniature transformer being carried out UV curing, adopt automatic pressing device described in the utility model that transformer is carried out pressure fixing, changed the position of putting forth effort when transformer carried out pressure fixing, namely directly push down the cylinder of skeleton both sides by the fin on the device center platen, the defective of having avoided the skeleton that may cause by pushing down stitch in the existing operation to tilt, so that skeleton can fit tightly with magnetic core, guarantee that skeleton is the level of state in magnetic core, improved product quality.And pressing plate is driven by cylinder, has alleviated labor strength, has realized that UV solidifies the automation of pressing, has improved production efficiency.
