TECHNICAL FIELD
[0001] The utility model relates to the industry technical field of work, concretely is a four rotary table line needle testing machine breaks out and falls off device. BACKGROUND
[0002] The test basic principle of four rotary table high density line needle testing machine is that the jig probe on the upper and lower compression structure and the contact on the measured product carry out high-precision alignment contact, carry out channel selection, and apply the test current or test voltage required by the test to the measured point to carry out conduction, insulation and other project tests. High-precision alignment contact means that the compression jig probe needs to maintain a relatively absolute physical position and cannot be offset. The jig on the upper and lower compression structure is fixed by a pneumatic cylinder, and the pneumatic cylinder structure is fixed by back pressure. If the air pressure is unstable or even abnormally broken during operation, the machine will trigger an alarm.
