Description

Pressure self-adaptation test module Technical Field The application relates to the field of chip testing, in particular to a pressure self-adaptive testing module. Background The existing chip also needs performance test after processing. The staff classifies the chips according to the performance test result, the chips with good detection results are good products, the chips with abnormal detection results are bad products, and after the bad products are recovered, the chips are sent to a laboratory by the staff to analyze the reasons of the problems, so that the improvement of production steps or production equipment is facilitated. The existing chip test module generally uses an air cylinder to drive a test pressure head to press down to detect the performance of a product. However, the existing chips are more in variety, and the cylinder directly drives the test pressure head to integrally press down, so that the test pressure requirements of different products cannot be met. Disclosure of utility model In order to improve the practicability of the test module and reduce the possibility of scratch phenomenon of chips in the test process, the application provides a pressure self-adaptive test module. The application provides a pressure self-adaptive test module, which adopts the following technical scheme: The utility model provides a pressure self-adaptation test module, includes test module body and the regulation subassembly of setting on the test pressure head of test module body, regulation subassembly is including setting up on the test module body and being used for the mount pad of location test pressure head, setting up on the mount pad and the elastic component that the bottom is connected with the test pressure head of test module body, setting up the setting piece in the elastic component upper end and setting up the impeller in the setting piece top, the impeller is used for driving the setting piece and reciprocates. By adopting the technical scheme, the pushing piece is used for pushing the positioning piece to push down the elastic piece, the elastic piece pushes down to drive the test pressure head to push down the test chip, the elastic piece provides extrusion supporting force for the test module, the possibility that the test pressure head directly and rigidly impacts the chip to damage the chip is reduced, meanwhile, the supporting force of the test pressure head to the chip is improved, the test effect of the test module is effectively improved, the practicability of the test module is improved, the extrusion degree of the pushing piece to the positioning piece is controlled according to different test pressures required by different products, and the test pressure is convenient for the staff to independently control the test pressure. Preferably, the pushing piece comprises a motor arranged on the mounting seat, a screw rod arranged at the output end of the motor and a pushing block in threaded connection with the screw rod, and the mounting seat is provided with a moving groove for moving the pushing block along the length direction of the screw rod. Through adopting above-mentioned technical scheme, the motor drives the lead screw and rotates, and the lead screw rotates and drives the impeller block and remove along lead screw length direction, and the shifting chute improves the stability that the impeller block removed.
