The present invention relates to a cutting system, more particularly, to a cutting system for cutting a plurality of workpieces.
In electronics manufacturing, a plurality of workpieces, for example, contacts, are often machined from a metal plate. The workpieces are machined by punching or cutting the metal plate with a known punching or cutting tool. However, known methods using the conventional punching or cutting tool have a slow processing speed and low production efficiency. Furthermore, the workpieces machined by the conventional punching or cutting tool have rough edges, reducing the quality of the workpiece.
An object of the invention, among others, is to provide a cutting system capable of cutting a plurality of workpieces in a single cutting process while improving the cut quality of edges of the workpieces. The disclosed cutting system comprises a moving mechanism, a cutter mounted on the moving mechanism, a support table having a material plate disposed thereon, and a fixation device including a pressing plate having a row of teeth defining a row of teeth slots. The row of teeth press the material plate on the support table while the moving mechanism drives the cutter to move along edges of the row of teeth slots. The cutter cuts a plurality of workpieces out of the material plate by a single cutting process.
The invention will now be described by way of example with reference to the accompanying figures, of which:
The invention is explained in greater detail below with reference to embodiments of a cutting system. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and still fully convey the scope of the invention to those skilled in the art.
The cutting system is shown generally in
The moving mechanism 100 is shown in
The cutter 200 is shown in
The support table 300 is shown in
The fixation device 400 is shown in
The pressing plate 410, as shown in
The force exerting mechanism 420, as shown in
A connection member 4221 is provided on the third corner of the second linking plate 422 and formed with a through hole. The threaded end of the connection rod 413 passes through the through hole of the connection member 4221 and is locked on the connection member 4221 by two fasteners, for example, nuts, at both sides of the connection member 4221. The pressing plate 410 is thus fixedly connected to the third corner of the second linking plate 422.
The assembly of the cutting system will now be described in greater detail with reference to
The use of the cutting system will now be described in greater detail with reference to
The cutting system is used with a material plate 500 as shown in
The material plate 500 is positioned on the support table 300, as shown in
The moving mechanism 100 drives a head of the cutter 200 to move along a predetermined trajectory based on a preset control program. During cutting of the material plate 500, the cutter 200 emits a laser beam, and as the row of teeth 412 press the sheet of material plate 500 on the support table 300, the moving mechanism 100 drives the laser head of the cutter 200 to move along edges of the teeth slots 401, so as to cut and form a row of workpieces 510. The workpieces 510 corresponding to the row of teeth 412 are cut out of the material plate 500 by a single cutting process. The edge 520 of the sheet of material plate 500 is cut off last, so as to separate the work pieces 510 from each other for use.
In the shown embodiment, the teeth 412 are identical with each other in size and shape, so that the row of workpieces 510 are identical with each other in size and shape. The present invention, however, is not limited to this, the row teeth 412 may be different from each other in size and shape, so that the row of workpieces 510 made from the material plate 500 are different from each other in size and shape.
Through the row of material dropping slots 301 in the top wall of the chamber 350, waste material cut from the material plate 500 falls into the chamber 350, and smoke and dust produced during cutting the sheet of material plate 500 enters into the chamber 350. The vacuum suction pipe 320 sucks the smoke and dust out of the chamber 350. The waste material falling into the chamber 350 through the material dropping slots 301 is collected in the material collecting slots 330 and is discharged through the smaller openings of the material collecting slots 330 after the bottom cover 340 is opened.
Advantageously, in the cutting system according to the invention, the workpieces 510 are cut out of the material plate 500 by a single cutting process, increasing cutting efficiency. Furthermore, the laser cutter 200 cuts a smooth edge on the workpieces 510, improving the cut quality of the edges of the workpieces 510.
