Hand feel test head

Abstract

The invention discloses a hand feeling test head, which comprises a vertical fixed frame and a test head assembly installed on the fixed frame. The test head assembly includes an elastic column, a sensor hanging plate, a load cell and a test head which are sequentially connected from top to bottom. The sensor hanging plate is supported by the limit block arranged on the fixed frame; the top of the elastic column is fixed on the fixed frame, and the bottom end of the elastic column is fixed on the top surface of the sensor hanging plate; The slide rails of the fixed frame are connected, and the slide rails are set vertically; one side of the load cell is suspended and fixed on the sensor hanging plate, and the bottom end of the load cell is connected with a test head; there is a gap between the load cell and the sensor hanging plate. The sensor overload protection groove, the bottom end of the test head is a free end, acting on the keys in the keyboard to be tested. The overall structure is simple and compact, the degree of automation is high, the test is accurate and efficient, and it has the sensor overload protection function, which is resistant to damage and has a long life, and the replacement cost is low.

Description

technical field [0001] The invention relates to a testing mechanism, in particular to a hand feeling testing head, which belongs to the technical field of components for keyboard automatic testing equipment. Background technique [0002] As the main input structure, keys are widely used in electronic products such as computer keyboards, mobile phones, and calculators; for electronic products such as computer keyboards, mobile phones, and calculators, keys must be tapped during work to make the key contacts conduct Disconnect to input letters, numbers, punctuation marks, etc. into the corresponding computer, mobile phone or calculator. [0003] Therefore, whether the quality of the keyboard and its functions operate normally will directly affect the stability of the operation of the electronic equipment. At the same time, the direct operating unit in the keyboard is the key, so the quality test of the key is a crucial link for the keyboard. In the keyboard production proces...
