The present invention relates to a laser processing apparatus for continuously processing a cylindrical element, and more particularly to a laser processing apparatus for cutting and bonding (fusion) processing of a fine filter network, yarn mesh, fine wire mesh, synthetic resin material to a certain size. It is about.

Conventional Patent Publication No. 10-2004-0016009 The manufacturing apparatus of the filter element for the oil filter is a fine mesh that is arranged from the upper side to the web supply stage, filter element manufacturing stage, and discharge web winding end and supplied from the web supply stage. A cylindrical filter element can be produced from a web of tape-shaped synthetic fiber tape. In the present invention, the filter element manufacturing stage is disposed on a web path extending between the web supply stage and the discharge web winding stage. The filter element manufacturing stage is installed on a platform lifted by an air cylinder and has a horizontal support plate and a hot wire support plate having two arms, a hot wire horizontally connected to the lower ends of two hot wire support rods extending below these arms, and a stretch paper on a horizontal support plate. A web guide plate which is installed through the roof and has web guide rods and web protection tubes extending at the ends thereof, and a web guide plate fixed at regular intervals below the web guide rods and web protection plates of the vertical movable plate where the heating wire is disposed between them, There is a known technique consisting of a web protection plate, a web fixing plate movably mounted relative to the web guide plate, and a loop forming rod extending upwardly of the web guide plate by an air cylinder installed on a horizontal movable plate movable left and right.

In addition, in the prior art Patent Publication No. 10-2004-0016009 of the manufacturing device of the filter element for the oil filter, the present invention is a web supply stage, filter element manufacturing stage, and discharge web winding end from the upper side in front of the base is disposed An apparatus for producing an oil filter filter element for producing a cylindrical filter element from a web on a fine mesh-like synthetic fiber tape supplied from a supply stage. According to the invention, the filter element manufacturing stage is arranged on a web path extending between the web supply stage and the discharge web winding end, so that the filter element manufacturing stage is mounted on a cylindrical support fixed to the base and the web can move in contact. 'C' shaped elastic plate with upper and lower coal pieces, an ultrasonic horn mounted on the front side of the elastic plate and having a long flat portion extending parallel to the width direction of the elastic plate at the top of the elastic plate and movable on the upper side of the ultrasonic horn A welding roller mounted on the carriage and a loop formed in the interior of the base at the position of the filter element manufacturing stage and extended and contracted by the air cylinder so as to advance to or retract from the two bullet pieces of the elastic plate. It consists of a rod and the front plate is placed on the upper side of the elastic plate, and two welding projections are formed on the main surface of the welding roller. The filter element had a known technique that is configured to heat fusion.

The loop forming rod described in the prior art is made to move between the web guide rod of the vertical movable plate and the lower web guide tube to the rear side of the web so as to form a loop from the web, while the loop is formed from the web by the loop forming rod. When formed, the two layers of webs are gripped and fixed, and the hot wire support plate on which the hot wire support rods are installed is lowered so that the hot wire passes through the web guide rods and the web protection plate and the two layers of webs that are gripped and fixed by the web guide plate and web protection plate It is configured to separate the loop from the web by melting cutting the connection part between the loop and the loop, but after forming the loop shape in the horizontal direction, the heat wire that can be cut as much as the width of the loop should be arranged so that the heat distribution of the heat wire that can be cut out at the moment As the melt cutting part is not cut sharply, the defective rate is increased. Had a problem.

In addition, since the connection surface of the loop presses the connection surface while the hot wire supporting rod equipped with the heating wire descends, there is a problem that the range of error is increased when processing a device requiring precision.

The loop forming rod described in the former latter is moved past the upper portion of the ultrasonic horn to form a loop from the web, and when the loop is formed from the web by the loop forming rod, the welding roller is placed on the upper plane of the ultrasonic horn. Although the connection between the loop and the web is melted and cut by moving through the connection between the loop and the loop, the connection between the loop and the loop separated from the web is separated and the remaining web is fused. As the number increases, the fusion roller is pressed and rotated on the upper portion of the ultrasonic horn, thereby causing a problem that the bonding surface of the fusion portion is not uniform and the bonding surface does not adhere uniformly.

In particular, the production cost per hour is increased during manufacturing and the material of the loop is limited, it was difficult to diversify the material with high strength.

Accordingly, an object of the present invention is to provide a factory value laser continuously processing the cylindrical element that can minimize the defect rate by sharply cutting the melt cutting part.
