Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a device for testing scratches on a surface of a mobile phone includes: cell-phone surface mar testing arrangement workstation 100, be located mar subassembly on the workstation and being located cell-phone clamping device on the workstation.
The mobile phone surface scratch test workbench is provided with a horizontal working surface. It can be understood that the utility model discloses do not restrict the shape of quick-witted surface mar test table, only need have a horizontal work face the workstation can. In one possible example, the machine surface scratch test station may be an i-beam.
The mar subassembly includes that one is fixed cylinder connecting plate 210, connection on the cell-phone surface mar testing arrangement workstation horizontal motion cylinder 220, connection on the cylinder connecting plate are in the mar gauge head fixed block 230 of horizontal motion cylinder front end, with mar gauge head fixed block threaded connection's bolt 240 and fixed connection are in the mar gauge head 250 of bolt one end. And the scratching measuring head points and scratches the surface of the mobile phone to be measured.
The horizontal movement cylinder can make the scratch measuring head perform linear movement in the horizontal direction. The adjusting bolt can adjust the position of the scratch measuring head in the vertical direction, so that the scratch measuring head can better contact the front or the back of the mobile phone to be measured. Or the depth of the scratch measuring head when the scratch measuring head scratches the front side or the back side of the mobile phone to be measured can be controlled.
In another embodiment, the horizontal motion cylinder is a double-acting cylinder. Because the horizontal movement cylinder is a double-acting cylinder, the horizontal movement of the horizontal movement cylinder is more flexible.
Referring to fig. 2, the mobile phone holding device includes a mobile phone placing base 310 and four mobile phone positioning devices 320 fixed on the mobile phone placing base and distributed in a matrix.
In another embodiment, a rotating disc 330 may be disposed under the handset placement base. The mobile phone clamping device can rotate by rotating the moving disc, so that the scratch measuring head of the dial indicator can contact with more positions on the front or back of the mobile phone to be measured.
The mobile phone positioning device comprises a rotating motor (not shown in the figure), a turntable 322 driven by the rotating motor, an air cylinder 323 fixed on the upper end surface of the turntable, and a mobile phone positioning block 324 linearly driven by the air cylinder.
The rotary motor drives the rotary disc to change the direction and stretch out and draw back when the cylinder drives the machine positioning block, so that the effect of testing and processing mobile phones with different lengths and widths can be achieved, and the adaptability is greatly improved.
Specifically, in one possible example, referring to fig. 3, the handset positioning block includes the handset positioning block body 3241 and a first groove 3242 on the handset positioning block body. It can be understood that the mobile phone positioning block with other shapes can be adopted, as long as the effect of clamping the mobile phone to be tested is achieved.
In another embodiment, the handset positioning device further comprises an angular displacement sensor that measures the angular displacement of the rotating electrical machine. In this way, the position of the rotating electrical machine can be more accurately controlled or known.
In another embodiment, the rotary electric machine is a DD direct drive motor. Unlike conventional motors, the large torque of the direct drive motor allows it to be directly connected to a motion device, thereby eliminating connection mechanisms such as a reducer, a gear box, a pulley, etc., and thus it will be referred to as a direct drive motor.
Because the motor is generally provided with a high-resolution encoder, the product can achieve one-level higher precision than the common servo. And because of adopting the direct connection mode, reduced because the positioning error that mechanical structure produced for the technology precision can be guaranteed, the requirement of installation has reduced a lot and the noise when using has also reduced a lot.
Above-mentioned cell-phone surface scratch testing arrangement, detection efficiency is high and the testing result is accurate.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
