Description

Crimping mechanism, testing device and operation machine

Technical Field

The invention relates to a crimping mechanism which can prevent a positioning piece from shaking randomly and can carry out fine adjustment and precise positioning so that a presser can be crimped with an electronic component really.

Background

In recent years, the number of contacts of an electronic component is increasing, and is increased to several tens of contacts, and correspondingly, the test socket of a testing apparatus must be provided with the same number of probes to electrically contact the contacts of the electronic component; because the inside of the probe is provided with the spring, in order to ensure that the contact of the electronic component is electrically contacted with the probe of the test seat, the test device utilizes a depressor to press the electronic component with default pressure so as to enable the electronic component to compress the spring of the probe, but the over or under of the pressure of the depressor affects the test quality.

Referring to fig. 1, the testing apparatus includes a machine 11, a circuit board 12 and a testing base 13 electrically connected to each other, the testing base 13 having a plurality of probes 131 for supporting and testing electronic components 14; a lower press 16 driven by the moving arm 15 to move is disposed above the test socket 13, a diaphragm 161, an air chamber 162 and a lower press fixture 163 are disposed inside the lower press 16, the air chamber 162 is connected to an air supply device through a conveying pipe (not shown), and two positioning members 164 are disposed at the bottom of the lower press 16; during testing, the moving arm 15 drives the pushing device 16 to move downward in the Z direction, so that the positioning element 164 is first inserted into the positioning hole 132 of the testing seat 13, and then the air supply device (not shown) injects air into the air chamber 162 to make the membrane 161 protrude and deform downward, and pushes the pushing fixture 163 to move downward in the Z direction to press and connect the electronic component 14, so that the electronic component 14 performs testing operation in the testing seat 13.

Since the moving arm 15 drives the pressing device 16 to make rigid displacement in the Z direction, if the positioning element 164 and the positioning hole 132 have a position difference, the pressing device 16 cannot correct the positioning element 164, so that the positioning element 164 cannot be inserted into the positioning hole 132, and the accuracy of pressing the pressing jig 163 is affected. However, if the moving arm 15 drives the lower pressing device 16 to move flexibly in the Z direction, the lower pressing device 16 is prone to be pulled by the gas transmission pipeline and the circuit wiring to shake arbitrarily, and the positioning element 164 cannot be inserted into the positioning hole 132 accurately, which also affects the accuracy of the pressing connection of the pressing fixture 163.

Furthermore, when the springs (not shown) of the tens of probes 131 of the test socket 13 are compressed by the pressing fixture 163, the tens of probes 131 generate a large reaction force on the electronic component 14, and the large reaction force pushes the whole set of the pressing unit 16 to perform a reverse displacement in the Z direction via the electronic component 14, so that the pressing unit 16 cannot press the electronic component 14 with a predetermined pressing force, and thus some contacts of the electronic component 14 cannot reliably contact the probes 131 of the test socket 13, thereby affecting the testing quality of the electronic component.
