Description

Hemming device capable of instantly adapting to the size of workpiece and a combination having the same

The present invention relates to a hemming device, and more particularly to a hemming device that can instantly adapt to the size of a workpiece and a combination having the device.

Before the development of printed circuit boards (PCBs), the connection between electronic components relied on direct wire connection to form a complete circuit. Now, printed circuit boards have become an absolute dominant role in the electronics industry. In the early 20th century, in order to simplify the manufacturing of electronic products and reduce the wiring between electronic components, people developed a method of replacing wiring with printing, which is to print/prepare conductive circuit patterns on an insulating substrate to form a complete circuit. It has also developed from a single-layer circuit board to a multi-layer circuit board until now.

The materials of the substrate are generally classified according to the insulating and reinforcing parts of the substrate. Common materials are bakelite, fiberglass and various plastic boards. After being cut into preset sizes, the subsequent conductive circuit pattern operation process is carried out. However, the burrs formed at the cutting point of the substrate will cause problems in the subsequent operation process such as cuts, powder pollution and defective rate. To solve the problems caused by burrs, a wrapping machine is used to apply a wrapping layer/glue layer on the cut edge/periphery of the substrate.

The commonly used hemming machine is mainly equipped with a roller with a vertical rotation axis and a gap adjacent to the roller on a movable base, wherein the roller is provided with an annular groove on the circumferential side surface. When the movable base moves along the periphery of a substrate, the annular groove of the roller first abuts against the periphery of the substrate and provides a coating layer/glue layer on the periphery of the substrate, and then the periphery of the substrate is The edge passes through the gap to modify the coating layer/glue layer; the annular groove is usually a V-shaped opening in the longitudinal section, which is not perfect for the upper and lower surfaces around the substrate in coating, and a gap also has its shortcomings in decoration. Moreover, when encountering substrates of different sizes and thicknesses, the commonly used hemming machine cannot be adjusted in time.

The main purpose of the present invention is to provide a hemming device that can instantly adapt to the size of the workpiece and a combination having the device, which can instantly adjust the position to adapt to substrates of different sizes and thicknesses.

The secondary purpose of the present invention is to provide a hemming device that can instantly adapt to the size of the workpiece and a combination having the device, which has better coating effect.

Another object of the present invention is to provide a hemming device that can instantly adapt to the size of the workpiece and a combination having the device, which has a better coating appearance.

Therefore, in order to achieve the above-mentioned purpose, the present invention provides a hemming device that can instantly adapt to the size of the workpiece and a combination having the device, which at least includes a first base, a second base, a third base, a fourth base and a fifth base; the first base can move linearly in a horizontal direction; the second base is slidably disposed on the first base, and a first coating portion is disposed on one side of the second base; the third base is slidably disposed on the first base horizontally; the fourth base is disposed on the third base The fifth base is slidably disposed on the third base; a second coating portion is provided between one side of the fifth base and one side of the fourth base; the first coating portion provides and covers a coating on one side of a workpiece, and the second coating portion provides and covers the coating on one side of the workpiece; the first coating portion is variable in position relative to the first base in the vertical direction, and the second coating portion is variable in position relative to the first base in the horizontal direction, and a gap is variably provided between the fourth base and the fifth base.
