Description

Technical Field

[0001] This utility model relates to the field of computer keyboard processing technology, specifically a computer keyboard laser engraving positioning fixture. Background Technology

[0002] Laser engraving, also known as laser carving or laser marking, is a surface treatment process that uses optical principles. Similar to screen printing and pad printing, it prints words or patterns on products. In the keyboard production process, laser engraving is used to print words on the keycaps of the keyboard, and the keyboard needs to be held by a positioning fixture during the laser engraving process.

[0003] Chinese patent document CN206717297U discloses a keyboard laser engraving positioning fixture, including a rectangular positioning disk. A quick-clamping mechanism is installed on each of the left and right sides of the top of the rectangular positioning disk. The top of the rectangular positioning disk has a keyboard receiving cavity and a keycap removal slot. The keyboard receiving cavity is located between the two quick-clamping mechanisms. There are two keycap removal slots, respectively located at the center of the front and rear sides of the keyboard receiving cavity. Each keycap removal slot extends into the keyboard receiving cavity, and its depth is greater than the depth of the keyboard receiving cavity. At least four keycap positioning blocks are installed inside the keyboard receiving cavity. When the quick-clamping mechanisms are in the clamping state, the pressure head of the quick-clamping mechanism falls into the keyboard receiving cavity. The fixture features a simple structure, ingenious design, and convenient operation, significantly improving the laser engraving yield.

[0004] The existing technology described above has the disadvantage of poor clamping and fixing effect when clamping and locking computer keyboards, which makes the computer keyboards prone to displacement and results in poor laser engraving quality. Therefore, it is necessary to develop a new type of computer keyboard laser engraving positioning fixture. Utility Model Content

[0011] Preferably, a pushing cylinder is installed on the positioning processing table, and the output end of the pushing cylinder is connected to a pushing head.

[0012] Preferably, the bottom of the positioning processing table is fixedly connected to a load-bearing base via a support frame, and the bottom of the load-bearing base is equipped with casters.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes elastic fixing clips and limiting stop plates to initially limit and fix both ends of a computer keyboard on a positioning processing table. Then, by using a first positioning cylinder and a second positioning cylinder, the limiting clip plates can be driven and controlled to limit and fix both ends of the computer keyboard. At the same time, the positioning chuck is used to further clamp and lock the sides of the computer keyboard, thereby ensuring the safety and stability of the computer keyboard during laser engraving operations and improving the laser engraving quality of the computer keyboard.
