Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a continuous loading and unloading device for cutting a keyboard positioning plate. Background Art

[0002] People input instructions and data into computers and direct the computers to work by operating the keyboard. The keyboard positioning plate is one of the keyboard structural parts. It is between the circuit board and the shaft of the keyboard keycap. The positioning plate mainly plays the role of fixing the shaft and receiving the pressing pressure of the shaft. The keyboard positioning plate is usually a relatively regular rectangular thin plate. Because it needs to be assembled with the shaft of the keyboard keycap through the positioning hole, the keyboard positioning plate needs to be processed with the positioning hole.

[0003] At present, due to the large number of keycaps on keyboards, keyboard positioning plates are usually processed by laser cutting or CNC processing. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, ablate or reach the ignition point quickly, so that the cutting part is disconnected from the raw material to obtain the desired pattern. Laser cutting replaces the traditional mechanical knife with an invisible beam, and has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs, and is gradually replacing CNC cutting process equipment.

[0004] In the prior art, when laser cutting the keyboard positioning plate, employees usually manually place the keyboard positioning plate on the positioning fixture, and need to spend a relatively long time on the positioning fixture to fix the keyboard positioning plate. For example, after the keyboard positioning plate is placed on the positioning fixture, it is necessary to twist multiple pressing pieces one by one to fix the keyboard positioning plate. Then start the cutting machine for cutting, and remove the keyboard positioning plate from the positioning fixture after completion. During cutting, employees spend most of their time waiting. The entire processing process relies on manual work by employees, and the production efficiency is low. Utility Model Content
