Description
Technical field
The present invention relates to a kind of keyboard clamping mechanism, more particularly to a kind of keyboard based on pressure and suction double action is filled
Clamp mechanism.
Background technology
The device that instruction and data is inputted during keyboard is run as computer, the feel of its button is that detection keyboard quality is good
One of bad index, and in order to ensure the feel quality of each keyboard, various keyboard-hand sense test equipments are arisen at the historic moment.Due to
Keyboard to be tested is generally on semi-finished product i.e. PCBA plus button in keyboard-hand sensing examination, be rigidly not enough to ensure its in assembling or
Movement keeps smooth during picking and placeing, and is often the state for having flexural deformation during arrival feel test station, and keyboard is put
Influence will be produced to the accuracy of test result by putting out-of-flatness, thus how to ensure keyboard it is smooth in test process be whole
The emphasis of test system.
At this stage, most of keyboard tester is all inhaled using relatively rough pressure plate structure or simple vacuum on the market
Attached structure fixes keyboard.
Existing keyboard pressing plate module fixed form is that the stage casing on a certain long side of pressing plate is fixed on using a cylinder, with two
Line slide rail is fixed on the both sides on this long side of pressing plate, pressing plate is pressed on keyboard using the contraction or release of cylinder, in pressing plate
Portion processes multiple square bit-avoiding slots, for depressing when avoid keyboard, be pressed in using the elongated strip material between square bit-avoiding slot
Gap location between keyboard is so as to reach the purpose for flattening keyboard.But, because whole pressing plate plane is equal after pressing plate is pushed
Meeting stress, and the mode that pressing plate is fixed only with one side can cause bulk strength not enough, and pressing plate is easily deformed, and service life is short etc.
Shortcoming；Meanwhile, pressing plate processes the remaining material of institute after button bit-avoiding slot due to testing requirement and the limitation of the profile of product, thinner thickness
Relatively thin, in processing, transport, insufficient strength in installation or test process easily produces local deformation, causes keyboard pressure uneven and goes out
Existing test error.
The fixed form of existing keyboard vacuum suction is then to install multiple vacuum slot groups in the support plate front of carrying keyboard
Part, each vacuum subassembly tail end both passes through support plate, and installs tight-lipped with being sent out afterwards with vacuum with tracheae and vacuum subassembly tail end tracheae
Raw device is connected, and produce certain negative-pressure vacuum using vacuum generator lives product by plastics suction.Due to vacuum group
The general length of part is longer, and every vacuum subassembly is required for individually connecing a tracheae, so such a structure is complex, occupies
Space is larger, and tracheae it is more unsightly and do not meet install safeguard simplicity, while also having limited to the installation of vacuum slot
Quantity, because the quantity of vacuum slot can not be arranged too much, it is possible that product absorption affinity is not enough to overcome because of keyboard plasticity
The situation for the elastic force for restoring and producing after deformation, causes product can not adsorb smooth risk larger.Vacuum suction is due to vacuum
Negative pressure maximum is not more than 1 atmospheric pressure, so the suction of each vacuum slot is certain, can not infinitely increase,
When large curved deformation occurs in keyboard corner, the total suction of vacuum at this overcomes the elastic force needed for deformation less than keyboard
When, vacuum can be destroyed and can not suck keyboard.Due to the out-of-flatness of product, operator needs to use hand flicking after product is placed
Product makes it entirely be contacted with vacuum slot so as to be adsorbed, in the process, because artificial operation can not ensure pressure
Size, can have the risk that product is subject to crushing.
Therefore, either pressing plate module fixed form either vacuum suction fixed form, all it cannot be guaranteed that can will be all
The smooth fixation of keyboard to be measured.
