Needle bed testing equipment

Abstract

This invention relates to a needle bed testing device, which includes a support device and two testing devices inside the machine. The testing devices include a drive module and a detection module. The detection module can be controlled by the drive module to move in three directions within the testing space inside the machine, and includes a detection lens and a probe assembly. This needle bed testing device can simultaneously perform spring probe testing on the needle bed using the two detection devices, which can significantly improve the efficiency of needle bed testing. After locating the distribution position of the spring probes through visual judgment, the needle bed testing device controls the probe assembly to press down the spring probes to perform height correction, so that the spring probes can be reliably installed on the needle sleeve of the substrate before performing the elasticity test. This can greatly improve the accuracy of the test and save the time of manual correction.

Claims

1. A needle bed testing device, capable of supporting a fixture, the fixture capable of clamping and positioning a needle bed, the needle bed testing device capable of performing testing operations on the needle bed, the needle bed testing device comprising: a machine base having an internal testing space; a support device disposed within the testing space of the machine base, the support device comprising two support platforms and two clamping components, the two support platforms being located on opposite sides of the testing space, the two clamping components being respectively disposed on the two support platforms, the fixture being capable of straddling the two support platforms and being clamped and positioned by the two clamping components; Two detection devices are respectively installed in the detection space of the machine. Each detection device includes a drive module and a detection module. The detection module is installed in the drive module and can control the detection module to move in three dimensions in the detection space. The detection module includes a detection lens and a probe assembly. The probe assembly is installed on one side of the detection lens and includes a lifting brake and a probe. The probe is connected to the lifting brake through a load cell and can drive and control the probe to lift and lower.

2. The needle bed testing device as claimed in claim 1, wherein each clamping assembly includes an end abutment, a side positioning member, and a stop mechanism, the end abutment being disposed at the end of a corresponding support platform, the side positioning member being disposed on a corresponding support platform and located at a position opposite to the two support platforms, and the stop mechanism being disposed on the support platform at the other end opposite to the end abutment, the needle bed being able to abut against the end abutments of the two clamping assemblies and being clamped and limited by the side positioning member and the stop mechanism of the two clamping assemblies.

3. The needle bed testing device as claimed in claim 2, wherein the stop mechanism includes a stop drive and a stop rod, the stop rod being connected to the stop drive, the stop drive being able to drive the stop rod to pivot, thereby limiting the fixture.

4. The needle bed testing apparatus as described in any one of claims 1 to 3, wherein each of the support platforms has a plurality of omnidirectional rollers arranged in an array.

5. The needle bed testing device as described in any one of claims 1 to 3, wherein the two support platforms are synchronously and vertically distributed on opposite sides of the testing space.

6. The needle bed testing device as described in claim 4, wherein the two support platforms are synchronously and vertically distributed on opposite sides of the testing space.
