Description
Technical field
The present invention relates to the technical fields accurately placing testee on automatic Test Table and being fixed, and specifically relate to
And a kind of device for quickly positioning tested circuit board on automatic Test Table and clamping it on testboard, especially relate to
And a kind of circuit board quickly positions and clamping device.
Background technique
With the development of social informatization and the progress of science and technology, all trades and professions are very big to the demand of circuit board, and make
For the guarantee of quality of circuit board, basic detection and functional test before factory are an essential links.To circuit board
Test job have the characteristics that repeated strong, fine degree is high, to improve testing efficiency and test job accuracy, reduce and survey
The labor intensity of examination personnel has the test equipment of some automations at present, can be to the circuit board being placed on its testboard
Automatically it is tested and provides examining report.But no matter circuit board tested using manual or automated test equipment, due to
The many kinds of of circuit board, size are different, quantity is larger, install on testboard and fixed tested circuit board all will
It is a relatively complicated job, automated test device is even more to propose to the installation site consistency of all tested circuit boards
It requires.
As the type of circuit board, shape, size are increasing, installation and replacement are tested circuit board on testboard
Work will restrict the efficiency of entire automatic test work the more next moon.Currently, generally using multiple band screw locking functions
Block to install on testboard and fixed tested circuit board, i.e., tested circuit board is placed on testboard in advance
Then some position moves block and blocks tested circuit board surrounding, finally tighten the screw on block, realizes tested electricity
The installation and fixation of road plate.It when needing replacing tested circuit board, needs first to unclamp block screw, repeats and new quilt is installed
Test circuit board.When testing same circuit board, this device needs to unclamp block screw repeatedly and repeats installation steps,
When testing various boards, needs to unclamp all blocks of surrounding, be laid out stop location again, therefore efficiency is lower, and by
The repetitive positioning accuracy of test circuit board is unable to get guarantee.Further, since all using rigidity between tested circuit board and block
The way of contact, the vibration of testboard will will cause the failure of these rigid contacts, so that tested circuit board loosens on testboard,
Test job can not continue.
Summary of the invention
It quickly positions and clamping device, can effectively solve in the prior art the object of the present invention is to provide a kind of circuit board
Installing and dismounting existing for circuit board detecting clamping device is inconvenient, test various boards are laid out block low efficiency again, test electricity
The repetitive positioning accuracy of road plate is unable to get guarantee and testboard vibration causes tested circuit board and circuit board positioning to clamp
The various problems such as the rigid contact failure between device, provide a kind of suitable for different size circuit board testing, Neng Goufang
