Abstract
The invention discloses a sliding force tester, which comprises a chassis and a driving motor arranged in the chassis, wherein a lead screw is fixed on an output shaft of the driving motor and is provided with a jig; the jig is provided with a guide post which is parallel to the lead screw; the two ends of the jig are provided with fixing plates positioned outside the chassis; each fixing plate is provided with an adjusting plate; the adjusting plate is provided with a force sensor; the surface of the chassis is provided with a display screen; a plurality of voltage transformers are connected between the display screen and the force sensor; and the side part of the chassis is provided with a motor speed regulator and a power switch which are connected with the driving motor. During working, a mobile phone shell is arranged on the jig, the driving motor is started to drive the lead screw to rotate, the fixing plates are moved relative to the jig, the force sensors are pressed against the two ends of the mobile phone shell, an obtained voltage signal is converted into a digital stream signal by using the voltage transformer, and the digital stream signal is displayed on the display screen and is compared with a preset value on the display screen, so that a sliding force test result is obtained.
Description
Technical field
The present invention relates to a kind of tester, be specifically related to a kind of dynamics tester that the slip dynamics of phone housing is tested.
Background technology
The shell of slide type mobile phone is in the process of using, need stand up to ten thousand times slip, can be to the front slide certain distance when shell stops suddenly because of inertia effect, the acting force that is produced in sliding process is for being sliding force, each phone housing all will carry out the detection of antiskid power degree before rolling off the production line, to guarantee that shell can phenomenons such as distortion, breakage can not occur in the guarantee period at mobile phone.
The dynamics tester of on the market phone housing being tested at present is subjected to the influence of temperature and equipment operation easily, often occurs reporting an error, and causes the data statistics out of true, brings the serious consequence of doing over again in a large number even stopping work to production.
Summary of the invention
Purpose of the present invention just provides a kind of stable performance, the dynamics that slides tester that measuring accuracy is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slip dynamics tester, comprise cabinet and be located at the interior CD-ROM drive motor of cabinet, be fixed with leading screw on the output shaft of CD-ROM drive motor, leading screw is provided with tool, tool is provided with the guide pillar parallel with screw mandrel, the tool two ends are provided with and are positioned at the outer fixed head of cabinet, fixed head is provided with adjustable plate, adjustable plate is provided with the dynamics sensor, the cabinet surface is provided with display screen, be connected with a plurality of transformation conveyers between display screen and the dynamics sensor, the cabinet sidepiece is provided with motor speed regulator and the power switch that is connected with CD-ROM drive motor.
Wherein, the described tool outside also is provided with a plurality of protection inductors and limit induction device, is provided with a plurality of cooling fans in the described cabinet.
The invention has the beneficial effects as follows: during work phone housing is placed on the tool, start CD-ROM drive motor then and drive the leading screw rotation, fixed head and tool are relatively moved, the dynamics sensor of allowing is pressed in the phone housing two ends, obtain being converted into the digital stream signal through the transformation conveyer behind the voltage signal, be presented on the display screen, and with display screen on the numerical value set in advance compare, slide the dynamics test result thereby draw.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
With reference to Fig. 1, shown in Figure 2, the invention discloses a kind of slip dynamics tester, comprise cabinet 1 and be located at CD-ROM drive motor 2 in the cabinet 1, be fixed with leading screw 3 on the output shaft of CD-ROM drive motor 2, leading screw 3 is provided with tool 4, tool 4 is provided with the guide pillar 5 parallel with screw mandrel 3, tool 4 two ends are provided with the fixed head 6 that is positioned at outside the cabinet 1, fixed head 6 is provided with adjustable plate 7, adjustable plate 7 is provided with dynamics sensor 8, cabinet 1 surface is provided with display screen 9, be connected with a plurality of transformation conveyers 11 between display screen 9 and the dynamics sensor 8, cabinet 1 sidepiece is provided with motor speed regulator 14 and the power switch 15 that is connected with CD-ROM drive motor 2, during work phone housing 10 is placed on the tool 4, start CD-ROM drive motor 2 then and drive leading screw 3 rotations, fixed head 6 and tool 4 are relatively moved, allow dynamics sensor 8 be pressed in phone housing 10 two ends, obtain being converted into the digital stream signal through transformation conveyer 11 behind the voltage signal, be presented on the display screen 9, and with display screen 9 on the numerical value set in advance compare, if in setting range expression test OK then, if not setting range then the status lamp 19 on the cabinet 1 show red, and report to the police, slide the dynamics test result thereby draw.
In addition; described tool 4 outsides also are provided with a plurality of protection inductors 12 and limit induction device 13; be provided with vacuum generator and air filtration variable valve 17 in the cabinet 1, be provided with a plurality of cooling fans 16 in the described cabinet 1, CD-ROM drive motor 2 devices such as grade are dispelled the heat; cabinet 1 top is provided with startup/scram button 18; the precision of this tester test dynamics can reach 0.01N, and repeatability is 0.01%FS, and non-linear is 0.02%FS; and stable performance, be the first-selection that substitutes the import tester.
The foregoing description is illustrative principle of the present invention and effect thereof only; and the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
