Description

[Detailed description of the invention] (Field of industrial application) The invention is applicable to, for example, electronic parts-related processing, plastic-related processing, electric wire-related processing, glass-related processing, paint/ink-related processing, or metal-related processing. The present invention relates to an apparatus that uses a heat source of parallel reflected light emitted from a heat source unit as a heat source during processing. More specifically, the present invention relates to a heat source unit using a heat ray, in which the shape of the parallel reflected light heat ray can be arbitrarily changed depending on the processing application.

[Conventional technology]

For example, in the field of electronic components, as LSIs become larger year by year, the number of ICs with many lead pins is rapidly increasing. For example, smaller flat-type IC packages (hereinafter sometimes referred to as flat-type IC packages)
As a soldering machine that connects IC (sometimes referred to as IC) to a printed circuit board, the soldering iron is pressed directly against the processing area where the leads of the IC package and the leads of the printed circuit board are to be connected. Alternatively, processing equipment using lasers was known [Light Metal Welding Vol. 17 (1979)]
No. 1] [Problem that the invention aims to solve] The above-mentioned device is used when the processed part of the processed part becomes wide, or when a heat ray is irradiated from the entire circumference of the processed part, such as when drying a product. Such hot wires could not be easily fabricated if the need arose. In addition, the former device had the disadvantage of extremely low work efficiency, since it was necessary to press the soldering iron directly against the workpiece to perform soldering. Furthermore, since the latter device requires optical equipment, the device is large and extremely expensive.

The inventors of the present invention succeeded in developing a device that can freely change the heat rays of the parallel reflected light from the heat source unit depending on the processing application.

The purpose of this invention is for cases where a narrow or wide irradiation width is required because the processed area is narrow or wide, or where irradiation from the entire circumference of the processed area is required. , or other similar processing parts, when various processing forms of the heating wire are required depending on the use of the processing parts, a heating wire that can easily produce parallel reflected light heating wires in such a form is used. The purpose is to provide a heat source unit.

[Means for solving problems]

The means of the present invention for solving the above problems consists of a heat source body formed in a rectangular shape, an end housing detachably attached to both longitudinal ends of the heat source body, and an end housing that is detachably attached to the heat source body. a horizontal piece with an attachment hole and a vertical piece with an attachment hole that is removably attached to the longitudinal end of the heat source body; A group of brackets having pieces, and a group of connecting plates formed in an angle or dogleg shape for assembling a heat source main body in a polygonal shape and detachably connecting and holding the ends of the bracket group, To provide a heat source unit using a hot wire, characterized in that when the above heat source body is assembled into a polygonal shape, the mounting holes formed in the bracket group and the mounting holes formed in the connecting plate group are aligned and fixed with screws. It is something.

[Effect]

In the case of a single heat source unit, one heat source unit is removably attached to the bracket by screwing screws into two mounting holes provided in the horizontal piece of the bracket.

When two heat source units are arranged in series, mounting holes for hanging are provided in the bracket at both ends in the longitudinal direction. Also,
There are two sets of mounting holes provided in the horizontal piece, one to one, for a total of four mounting holes. Therefore, two heat source units are mounted adjacently to a total of four mounting holes in this one-to-one pair. In this case, since there are no obstructive parts on the sides of the heat source units, the pair of heat source units can be brought into close contact with each other. Therefore, even though two heat source bodies are arranged side by side, a uniform heating wire with no gaps in the width direction can be produced.

Further, in the case of arranging three heat source units in series, the bracket is provided with three sets of mounting holes provided in the horizontal piece, six in total, in one-to-one pairs. Therefore, in the case of this bracket, three heat source units are mounted adjacently in parallel.

Further, in the case of arranging four heat source units in succession, the bracket is provided with four sets of mounting holes provided in the horizontal piece in one-to-one pairs, for a total of eight mounting holes. Therefore, in the case of this bracket, four heat source units are mounted adjacently in parallel.

Further, the bracket used when four heat source units are successively arranged in a square shape is generally the same as the single bracket described above. The length of this bracket is slightly longer than that of a single bracket. This bracket is provided with screw holes at both longitudinal ends thereof. Therefore, the heat source units with brackets attached are arranged in a square shape, and angled connecting plates are applied to both longitudinal ends of the adjacent brackets, and screws are screwed into the screw holes provided in the plates. It can be attached integrally. Then, a square processing space surrounded by the four heat source units is formed.
By passing the workpiece through this workspace, uniform heat rays are irradiated from the entire circumference of the workpiece, and desired workpieces such as drying can be performed as a furnace.

Finally, the bracket when the heat source units 1 are successively arranged in an octagonal shape is the same as the bracket when the heat source units 1 are arranged in a square shape. Therefore, by arranging the heat source units with brackets attached in an octagonal shape and screwing the longitudinal ends of the adjacent brackets into the screw holes of the dogleg-shaped connecting plate, the heat source units can be integrated. Attach to. Then, an octagonal processing space surrounded by eight heat source units is formed. Therefore, by passing a workpiece through this processing space, desired processing operations such as drying can be performed as in the case of the square processing space, for example, as in the case of the square processing space.

The embodiments of the present invention shown in the drawings will be described below, but the invention is not limited thereto.

[Effect of idea]

As explained above, the present invention uses brackets for single, double, triple, five, or square, octagonal, or other arbitrary polygonal shapes to place a plurality of heat source units in a parallel state or in a polygonal shape. Since they are configured in combination, it is possible to freely widen or narrow the heating wire width according to the shape of the processing part of the processed part, and there are no parts on the sides of the heat source unit that get in the way. Since there are no heat source units, a plurality of heat source units can be placed closely adjacent to each other. Therefore, even though a plurality of heat source bodies are arranged in parallel, it is possible to produce uniform parallel reflective heat rays without gaps in the width direction or circumferential direction. Also, for example, if the heat source lamp burns out and needs to be replaced,
By removing the end housing from the heat source body, the lamp can be easily removed without tampering with other parts. Furthermore, when the heat source unit is configured in a polygonal shape, the parallel reflected light can be uniformly irradiated from the entire circumference of the workpiece installed in or passed through the workspace.
Therefore, since the entire circumference of the processed portion receives uniform parallel reflected light, processing can be performed under uniform processing conditions over the entire area.
