Abstract

The invention relates to a clamp, in particular to a clamp for sealing detection of an electronic packaging shell. The clamp for sealing detection of the electronic packaging shell comprises a pressing board, a detection platform and a pressing rod. The pressing board is installed on the detection platform through a bolt, and the lower side of the detection platform is connected with a leak detector connector. A circular hole is formed in the center of the upper surface of the pressing board, a counter bored hole is formed in the lower surface of the pressing board, the diameter of the counter bored hole is larger than that of the circular hole, and the counter bored hole is communicated with the circular hole. The counter bored hole is filled with a soft rubber board, a ventilation hole is formed in the center of the soft rubber board, a through hole is formed in the center of the detection platform, a workpiece is buckled to the ventilation hole inversely, the upper edge of the workpiece and the soft rubber board are sealed, and a cavity of the workpiece is communicated with the leak detector connector. One end of the pressing rod is fixed to the upper surface of the pressing board through a support, a pressing head is installed on the pressing rod, and when the pressing rod is pressed downwards, the pressing head presses the bottom surface of the workpiece. The clamp for sealing detection of the electronic packaging shell can correspond to workpieces in various sizes flexibly, and a detection port and a detected product can be well sealed without using vacuum grease.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for sealing detection of an electronic packaging shell. Background technique [0002] The existing sealing performance test of electronic device packaging shell adopts vacuum leak detection method, and uses helium mass spectrometer leak detector to detect its air leakage rate. The diameter of the mouth is large, which cannot be adapted to the detection of this type of product. At the same time, the workpiece to be tested needs to be lined with a soft rubber plate between the detected port of the workpiece and the detection platform. In order to prevent air leakage, vacuum grease must be evenly applied on the rubber plate and the workpiece to ensure that the workpiece under test , soft rubber plate, and no air leakage between the detection ports, the test of the workpiece to be tested can be completed. However, the use of vacuum grease will pollute the product, and it is difficult to achie...
