Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] A kind of laser drilling machine, refer to figure 1 , Figure 10 and Figure 11 , which includes a frame 109 and a feeding device 1, a laser device 3 and a discharging device 2 that are all arranged on the frame 109. When processing a flexible circuit board, the flexible circuit board wound on the core tube is first passed through the feeding device. Device 1 delivers. In this embodiment, the preferred feeding device 1 includes a feeding transmission frame 11 that is slidably arranged on the frame 109, and several feeding transmission rollers 13 that are rotated on the transmission frame. The feeding roller 12 is set on the feeding transmission frame 11, and the winding core tube is placed on the feeding roller 12, and because the end surface of the flexible circuit board may be inclined during the processing process, and due to the precisio...

Abstract

The invention discloses a laser drilling machine, which comprises a feeding transmission frame and a plurality of feeding transmission rollers rotatably arranged on the transmission frame. The feeding transmission frame is provided with a tensioning part for tensioning a flexible circuit board. A sliding hole extending in the vertical direction is provided on the feeding transmission frame, and a slider that slides and fits with the sliding hole is provided on the tensioning part, and when the transmission speed of the flexible circuit board suddenly becomes faster, the flexible circuit board The part of the board pressed by the tension part will push the tension part up, and since the tension part itself is drooping by its own gravity, when the bent part of the flexible circuit board generates a relatively large force, the flexible circuit The plate pushes the tension up, which prevents the flex from being over-tensioned.

Description

technical field [0001] The invention relates to the field of mechanical drilling, more specifically, it relates to a laser drilling machine. Background technique [0002] Drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target to leave a cylindrical hole or hole on the target by means of rotary cutting or rotary extrusion. Also known as drilling rigs, punching machines, drilling machines, through-hole machines, etc. The expected effect is achieved by drilling precision parts. Drilling machines include semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs; most companies consider fully automatic drilling machines as the development direction . [0003] However, in recent years, as the integration of printed circuit boards (also known as PCBs) is getting higher and higher, and electronic products are developing towards portability and function-intens...
