Embodiment 1

[0018] Embodiment 1: It can be clearly seen from Fig. 1 that this is an electromagnetically driven single-set weight gravity finger. The so-called "single-weight gravity finger" means setting a weight on the test weight gravity finger. The weight gravity finger of the single group is composed of a shaft 1 , a weight 10 , an electromagnetic drive mechanism 4 , a shaft return spring 2 and a mounting seat 6 . The middle part of the shaft 1 is provided with a first limit buckle 8, and the end is provided with a second limit buckle 9; the weight 10 is a tapered cylinder, and its center is provided with a shaft hole 11 for the shaft 1 to be introduced into. , the shaft hole 11 is provided with a section of the limit section 12 for the second limit buckle 9 on the shaft 1 to move up and down; Line 3 is composed. The top of the shaft 1 is inserted into the cylindrical coil 5 of the electromagnetic drive mechanism 4, the top of the shaft 1 is provided with a return spring 2 connected ...

Embodiment 2

[0025] Embodiment 2: It can be clearly seen from Fig. 2 that this is an electromagnetically driven double-weight gravity finger. The so-called "two-group weight gravity finger" is exactly to set two weights on the weight gravity finger. The basic structure of this "double weight gravity finger" is the same as that of Embodiment 1, the only difference being that an upper weight 15 is added in the middle of the shaft 1 . That is: add a third limit buckle 14 in the middle of the shaft 1, add an upper weight 15 to the shaft 1 at the third limit buckle 14, and the upper weight 15 is columnar, with a hole in the center for the shaft 1 to shuttle. Shaft hole 16, the shaft hole 16 is provided with a limit interval 17 that cooperates with the third limit buckle 14 on the shaft rod 1, and the upper weight 15 can move up and down along the shaft rod 1 within the range of the limit interval 17.

Embodiment 3

[0032] Embodiment 3: It can be clearly seen from Fig. 3 that this is a cylinder-driven single-set weight gravity finger. Its basic structure is the same as that of Embodiment 1, the only difference is that the driving mechanism is the cylinder driving mechanism 18 . The cylinder driving mechanism 18 is composed of a cylinder body 19 and a piston rod 20 disposed therein, and an upper air inlet 21 and a lower air inlet 22 are provided at both ends of the cylinder body 19 . The piston rod 23 protrudes from one end of the cylinder body 19 to become a shaft rod for weight installation, and the cylinder driving mechanism 18 impels the piston rod 23 to move downward. A reset spring 2 can be sleeved on the piston rod 23 inside the cylinder body 19 .

[0033] The piston 20 in the cylinder 19 is driven to move up and down by controlling the air volume input to the upper and lower air inlets 21 and 22 at both ends of the cylinder 19 of the cylinder driving mechanism 18, and then drives ...

Abstract

A kind of code gravity point includes: one axis pole which the end is set with at least one movable code in the direction of the axis in a limit range, the axis pole is set with the driving device and the replacement spring; also the installing seat is set on the axis pole. The set code is pressed on the detected switch by the driving device controlling the code to detect the pressure of the button. If the weight of the code can't make the switch open, the detected switch is the disqualify product. So it can instead the detection by the manufacture. So it can detect the over sensitivity and over pressure. Therefore, it has the quick detection and good precision.

Description

technical field [0001] The invention relates to electronic product testing equipment, in particular to a weight gravity finger suitable for being connected with an electronic testing instrument to automatically test key switches. Background technique [0002] Today, as science and technology are more and more developed, electronic equipment is widely used, and the key switches on the accompanying electronic equipment are also widely used. These key switches are metal, plastic, and electronic. For example: computer keyboards, control panels on household appliances, mobile phone keypads, human-machine interface touch panels, etc. Before this type of electronic product leaves the factory, it is necessary to test the configured key switch. In the past, the test method was to manually press one by one to check whether these key switches are turned on. Pressing by hand has the following disadvantages: [0003] (1) The test efficiency is slow; [0004] (2) The strength is irre...
