Abstract
The utility model discloses a finger pressure detection device which comprises a support seat and a press finger. A press touch end and a connection end are arranged on the press finger. The press touch end penetrates through the support seat to press and touch a sample to be measured, and a detachable weight is installed on the connection end. According to the finger pressure detection device, the detachable weight is installed on the press finger, the press finger can move downwards under the effects of self gravity and the gravity of the weight in test, the press touch end presses and touches the sample to the measured, namely added pressure is sum of the gravity of the press finger and the gravity of the weight. The applied pressure is accurate, and the finger pressure detection device improves accuracy of the sample to be measured. Therefore, the finger pressure detection device can replace weights with different masses according to test parameters of different samples to be measured. The finger pressure detection device is simple in structure, low in cost and convenient to operate. The finger pressure detection device is used for detecting electronic products with keys and touch screens.
Description
Technical field
The utility model relates to a kind of pick-up unit in the electronic device accessory production research field, particularly a kind of finger pressure pick-up unit.
Background technology
The electronic product of band button or touch-screen is more and more at present, and output is also increasing.Automatic testing button of industry and touch-screen demand are also increasing.Generally all need testing apparatus that testing sample is detected, this testing sample comprises the electronic product of button or touch-screen.
Existing testing apparatus is difficult to control to the dynamics of pushing, and perhaps directly controls the pressure of gas finger with expensive high accuracy number air pressure valve, and needing pressure transducer to be used just simultaneously can achieve the goal.A general cover high accuracy number air pressure valve, senior gas finger and pressure transducer, their threes' cost is about 10,000 yuan.And 5 tests of the minimum needs of the detection of testing sample, in that cover test macro finger pressure detect this will 50,000 yuan of costs, this is with high costs.
Except the above-mentioned equipment cost of mentioning was expensive, also there was following shortcoming in existing pick-up unit:
1, can't do accurate control to the pressure that is applied to testing sample;
If 2 with precision digital air pressure valve and pressure transducer control gas finger pressure, cost an arm and a leg, and digital air pressure valve needs regularly to Weights and Measures Bureau's verification.
The utility model content
The purpose of the utility model is to provide a kind of finger pressure pick-up unit.
The solution that the utility model solves its technical matters is: a kind of finger pressure pick-up unit; Comprise supporting seat and end finger; Said end finger is provided with to press contravention and link, said pressure contravention to pass can to press behind the supporting seat and touches testing sample, and removable counterweight is installed on the said link.
As the further improvement of technique scheme, also comprise the control system of cylinder and control cylinder work, said counterweight below is provided with the pallet that counterweight is vertically moved, and said pallet connects with the output terminal of cylinder.
As the further improvement of technique scheme, said cylinder below also is provided with limited block.
The beneficial effect of the utility model is: the utility model is through being equipped with removable counterweight on end finger, and so when test, end finger can be under the effect of the gravity of self gravitation and counterweight; Down motion is pressed contravention to press and is touched testing sample, and the pressure that promptly adds is the gravity sum of the gravity and the counterweight of end finger; This applied pressure very accurately improves the accuracy rate that detects testing sample, like this; Can change the counterweight of different quality according to the test parameter of different testing samples, the utility model is simple in structure; Cost is low, is convenient to operation.
The utility model is applied to detect in the electronic product of band button or touch-screen.
Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specify the application of the utility model in the electronic product that detects band button or touch-screen.
With reference to Fig. 1, a kind of finger pressure pick-up unit comprises supporting seat 5 and end finger 1, and said end finger 1 is provided with to press contravention 2 and link 3, said pressure contravention 2 to pass can to press behind the supporting seat 5 and touches testing sample, and removable counterweight 4 is installed on the said link 3.
Through removable counterweight 4 is housed on end finger 1, so in when test, end finger 1 can be under the effect of the gravity of self gravitation and counterweight 4, down motion; Press contravention 2 to press and touch testing sample, the pressure that promptly adds is the gravity sum of the gravity and the counterweight 4 of end finger 1, and this applied pressure very accurately improves the accuracy rate that detects testing sample; Like this, can change the counterweight 4 of different quality according to the test parameter of different testing samples; The utility model is simple in structure, and cost is low, is convenient to operation.
Further as preferred embodiment, also comprise the control system of cylinder 7 and control cylinder 7 work, said counterweight 4 belows are provided with the pallet 6 that counterweight 4 is vertically moved, and said pallet 6 connects with the output terminal of cylinder 7.When pick-up unit detected end finger 1 below testing sample is arranged, control system sent instructions and lets the output terminal of cylinder 7 down move, and promptly counterweight 4 has lost support; Counterweight 4 is down motion under the gravity of himself; And force end finger 1 down to move, and touch testing sample until pressing contravention 2 to press, promptly be applied to the gravity sum that pressure on the testing sample equals the gravity and the end finger of counterweight; Applied pressure very accurately improves the accuracy rate that detects testing sample.After accomplishing detection, the output terminal of cylinder 7 up moves and drives counterweights through pallet 6 and returns back to virgin state, waits for the detection of next testing sample.
Further as preferred embodiment, said cylinder 7 belows also are provided with limited block 8, and limited block 8 plays the position limitation protection effect.
More than be that preferred embodiments to the utility model specifies; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
