Embodiment Construction

[0064] The present invention will be described below in conjunction with specific embodiments.

[0065] Such as Figure 1 to Figure 12 As shown, a keyboard electrical function testing machine includes a frame 10, and the frame 10 includes a lower bottom plate 11, a left side plate 12 installed above the left end of the lower bottom plate 11, and a left side plate 12 installed on the right end of the lower bottom plate 11. The right side plate 13 on the top, the top of the lower bottom plate 11 can be equipped with a left and right test bench 20 and a right test bench 21 arranged symmetrically between the left side plate 12 and the right side plate 13, and the left and right test benches 21 can be moved back and forth relatively. Located on the right side of the left test bench 20, the left test bench 20 and the right test bench 21 respectively include a test bench 22 and a bottom mold 23 installed on the upper surface of the test bench 22, and the upper surface of the bott...

Abstract

The invention discloses a machine for testing the electrical function of a keyboard. The machine is of a double-test-table structure, and therefore the time for fetching and placing the keyboard can be effectively shortened, and test efficiency can be improved. In the working process, the keyboard is accurately clamped and positioned through a keyboard clamping and positioning assembly, a pressing fixing assembly clamps and fixes a connecting flat cable of the keyboard to be tested; a left stepping motor and a right stepping motor drive a left test table and a right test table to move backwards to enter the position under a keyboard knocking assembly, a prepressing rod rolls keys of the keyboard before the keyboard enters a knocking region, prepresses the keys of the keyboard and simulates the pressed movement of the keys, a lead screw servo motor drives key knocking heads to horizontally move, and an electric control cabinet controls the key knocking heads to move and simulates knocking key movements. In the whole test process, a displayer can display a test result in time for users to conveniently check. Accordingly, the machine can efficiently and automatically detect the electrical function of the keyboard, in other words, the machine has the advantages of being high in working efficiency, positioning accuracy and flexibility.

Description

technical field [0001] The invention relates to the technical field of keyboard testing devices, in particular to a keyboard electrical function testing machine. Background technique [0002] As the main input structure, keys are widely used in electronic products such as computer keyboards, mobile phones and calculators; On and off, so as to input letters, numbers, punctuation marks, etc. into the corresponding computer, mobile phone or calculator. [0003] In the production process of keyboards (including computer keyboards, mobile phone keyboards, and calculator keyboards, etc.), when the quality inspection of the finished keyboard must be carried out before production, it is necessary to hit each key to test its rebound and contacts. on and off. However, the keyboard testing devices in the prior art generally have the defects of low work efficiency, poor positioning accuracy and insufficient sensitivity. Contents of the invention [0004] The object of the present i...
