Description

CONVEYOR PROFILE FOR REFLOW APPARATUS FOR REFLOW DEVICE

The present invention relates to a conveyor profile for a reflow apparatus, and more particularly to a conveyor profile for a reflow apparatus capable of effectively preventing thermal deformation of a conveyor for conveying a substrate during a reflow process.

Usually, the substrate soldering apparatus is for mounting electronic components on a substrate, and soldering is performed by a reflow apparatus.

Such a reflow apparatus is divided into a preheating region, a reflow region, and a cooling region, which are mounted before the soldering process.

The preheating area and the reflow area are provided with a heater and a fan, respectively, though not shown in the drawings.

The preheating area and the reflow area are provided with conveyors passing through these areas.

Accordingly, the substrate is moved along the conveyor, and the electronic component is mounted through the heat source of the heater in the preheating area and the reflow area.

That is, the substrate is coated with solder at every position where the electronic component is mounted before entering the preheating area. The solder is soldered through the preheat region and the reflow region, and the electronic component is installed at the soldered location.

However, in conventional reflow facilities, heaters are provided on the upper and lower portions of the conveyor in the reflow region, so that the heat of the heaters is transferred to the substrate through the blower to be soldered, There is a problem that is damaged.

That is, the heat source generated by the heater is usually at a temperature of 240 to 250 ° C., while the non-heat resistant part of the power related part has a lower critical temperature. Accordingly, in the case of a non-heat-resistant component, if the heat of the heater on the conveyor is directly applied to the non-heat-resistant component, the component is damaged and defective products are generated.

Here, the support for supporting the process line in the reflow line having the above characteristics is usually provided with an aluminum profile.

The conventional profile is exposed to the high temperature environment generated during the reflow process.

Therefore, in the past, when thermal deformation occurs along the axial direction of the profile as described above, there is a problem that the conveying path of the conveyor is twisted and the rigidity itself is reduced, and the device itself is damaged due to frequent deformation.

Prior art related to the present invention is Korean Patent Laid-Open Publication No. 10-2004-0058861 (published on Jul. 2004.07.05), which discloses a technique for an aluminum profile for a belt conveyor.

An object of the present invention is to provide a conveyor profile for a reflow apparatus which can effectively prevent thermal deformation of a conveyor for conveying a substrate during a reflow process.

In a preferred embodiment, the present invention provides a conveyor profile for a reflow apparatus.

The support portion includes the pair of support members.

Preferably, each of the pair of support members is provided with a cut-out groove formed so as to be exposed upward.

And a rotation hole passing through the tension shaft is formed with the cutout groove as a boundary.

It is preferable that the elastic portion is disposed in the cutout groove.

The elastic portion may include an elastic spring disposed in the cutout groove in a state of being fitted to both ends of the tension shaft portion and having both side portions elastically supported on both side walls of the cutout groove.

The elastic spring preferably further comprises a spacing member.

It is preferable that the spacing member is disposed between the elastic spring and one side wall of both side walls of the cutout groove.

It is preferable that the spacing members are formed so as to be arranged adjacent to each other.

Preferably, the spacing member is disposed to be sandwiched between both ends of the tension shaft portion.

The tension shaft portion preferably includes a pair of tension shafts.

Preferably, the pair of tension shafts are respectively installed at one upper end and lower end of the profile body portion.

Hereinafter, a conveyor profile for a reflow apparatus of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing a conveyor profile for a reflow apparatus of the present invention.

1, a conveyor profile 300 for a reflow apparatus according to the present invention includes a pair of supports 310, a profile body 320, a tension shaft 330 and an elastic portion 340, .

Each configuration will be described.

The conveyor profiles 300 for the reflow apparatus according to the present invention are installed in a plurality of spaced intervals along the width direction in the apparatus.

The pair of supports 310 according to the present invention are arranged to face each other at intervals.

The pair of supports 310 are formed to have the same structure.

Each of the pair of supports 310 includes a support member 311.

The supporting member 311 is formed with a cutting groove 311a which is cut so that an upper end thereof is exposed upward.

The incision groove 311a is formed in a '

Figure 112016024534717-pat00001
'Shape.

The supporting member 311 is formed with a through hole 311b.

The through holes 311b are formed on both sides of the boundary of the cutout groove.

The through hole 311b is perforated so as to be exposed to the outside of the support member 311. [

Both ends of the tension shaft portion 220 are engaged with the through holes 311b formed in the pair of support members 311 in the present invention.

Fig. 2 is a perspective view showing a support according to the invention, and Fig. 3 is a partially cutaway perspective view showing a tension shaft and a profile body according to the invention.

The profile body 320,

Referring to FIGS. 2 and 3, the profile body 320 according to the present invention may be formed of an aluminum material.

The profile body 320 has a predetermined length.

Both ends of the profile body 320 may be connected to a pair of supports 310.

The profile body 320 may have a rectangular hollow 321.

Although not shown in the drawing, the profile body 320 may be formed with a plurality of vent holes communicating with the outside.

The vent holes may be formed by venting the pressure formed in the hollow in accordance with the external heat to prevent deformation.

A reinforcing rib 322 may be formed at one side of the profile body 320 so as to protrude at intervals to maintain rigidity.

The reinforcing ribs 322 are formed along the longitudinal direction of the profile body 320 and protrude to one side.

The tension shaft portion (330)

3 and 4, the tension shaft portion 330 according to the present invention has tension shafts having lengths.

In the present invention, it is preferable that the tension shaft comprises two pieces.

Each tensile axis is installed to penetrate the profile body 320.

Both ends of the tension shaft are protruded to the outside through both ends of the form body 320.

Both ends of the tension shaft projecting through both ends of the profile body portion 320 are disposed so as to be fitted into the through holes 311b formed in the pair of support members 311. [

The tension shaft according to the present invention includes two tension shafts and is installed to penetrate the upper and lower ends of the profile body 320.

Therefore, a pair of through holes 311b are formed in the pair of support members 311 so as to correspond thereto.

Here, the pair of through holes 311b are formed so as to be exposed to the outside, and do not regulate both ends of the respective tension shafts.

The elastic portion 340,

The elastic portion 340 according to the present invention is disposed in the cutout groove 311a in such a state that it is fitted to both ends of the tension axis.

The elastic portion 340 includes elastic springs whose both side portions are elastically supported on both side walls of the cutout groove 311a.

In addition, the elastic spring further includes a spacing member 341. [

The spacing member 341 may be disposed between one side wall of the side walls of the elastic spring and the cutout groove 311a.

Here, the spacing members 341 may be arranged to be adjacent to each other.

The spacing member 341 is disposed to be sandwiched between both ends of the tension shaft.

According to the above configuration, the spacing member 341 according to the present invention can maintain a space between the elastic spring and one side wall of the cutout groove 311a.

In addition, the interval at which the holding member 341 is held can be variably controlled according to the number of the spacing members 341 installed.

With reference to the above configuration, the profile body 320 according to the present invention is installed in the reflow apparatus and is exposed to a high temperature above a certain level during the reflow process.

In addition, the profile body portion 320 located in the cooling region outside the reflow region can be exposed to a cooling temperature below a certain level.

Accordingly, the profile body 320 according to the present invention is different in temperature atmospheres exposed according to the installation position.

At this time, the profile body 320 according to the present invention is elongated or contracted along the longitudinal direction to generate a variable amount of length.

Here, in the profile body portion 320 according to the present invention, the two tension shafts are installed so as to penetrate the upper and lower ends to maintain the rigidity and are elastically supported by the respective elastic springs at both ends thereof. Therefore, The tension can be maintained.

In addition, since both ends of the tension shaft are turnably supported by the pair of elastic springs in the present invention, there is an advantage that the length of the profile body portion 320 itself can be reduced to a certain value or less.

That is, the embodiment according to the present invention can maintain the rigidity above a certain level and reduce the volume by installing the tension shafts.

Therefore, there is an advantage that the reflow apparatus itself can be downsized.

4 is a view showing another example in which the tension shaft according to the present invention is installed.

Referring to FIG. 4, the tension shaft 330 according to the present invention may be provided in three or more than two.

Further, the tension shafts 330 according to the present invention may be formed so that their diameters are different from each other.

Accordingly, it is possible to implement the rigidity at a plurality of positions of the profile body portion 320 differently from each other, so that a tension axis having a larger diameter can be used at a portion relatively weak in rigidity.

In addition, although not shown in the drawings, the tension shaft 330 according to the present invention may pass through the profile body 320, but may be coupled in a screwed state.

Accordingly, it is possible to increase the fastening force between the profile body 320 and the tension shaft 330 to prevent relative slip during rigidity and elastic flow.

The elastic force of the elastic spring according to the present invention is preferably designed to be proportional to the diameter of the tension shaft.

5 is a view showing another example of the elastic portion according to the present invention.

The elastic part according to the present invention may use an elastic spring as described above, but an elastic cylinder 350 having an elastic force may also be used.

In this case, the cylinder 350 is fixed to the spacing member 341, and the shaft 351 elastically stretched and contracted from the cylinder 350 can be supported on one side wall of the incision groove.

Accordingly, in the present invention, when both ends of the tension shaft 330 are held constant by using the elastic cylinder 350, the problem caused by elastic deformation of the spring itself can be solved.

In addition, there is an advantage that the elastic force can be variably controlled by forming a certain pressure in the elastic cylinder 350 to maintain the elasticity, and varying the pressure through a pressure regulating device (not shown).

According to the above construction and operation, in the embodiment according to the present invention, when the conveyor profile is cut by a required length by providing two or more tension shafts based on the pair of supports, It is possible to improve the responsiveness according to the deformation and the natural deformation according to the size of the profile, and to reduce the profile size itself, thereby achieving compactness of the apparatus.

As described above, the concrete embodiment of the conveyor profile for a reflow apparatus of the present invention has been described. However, it is apparent that various modifications can be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
