Description

Technical Field

[0002] In the current field of mobile phone glass cover plate testing technology, mobile phone glass cover plates, also known as mobile phone cover plate glass, are mainly installed on the surface of touch screens. This glass cover plate has multiple functions. First, it can protect the mobile phone screen from external damage, such as impact, scratches, etc. After the processing of the mobile phone glass cover plate is completed, a sample pressure test is required to detect the pressure resistance of the mobile phone glass cover plate.

[0003] The utility model patent with the authorization announcement number CN210375978U discloses a mobile phone glass cover pressure test device, including a support base and a pressure monitoring mechanism, a mounting frame is arranged above the support base, and a pressure monitoring mechanism is arranged in the middle of the upper end of the mounting frame, and the pressure monitoring mechanism includes a mounting seat, a pressure monitor, a limit plate and a pressure contact block, and a pressure monitor is arranged at the front end of the mounting seat, a limit plate is arranged at the lower end of the pressure monitor, and a pressure contact block is arranged below the limit plate. Compared with the existing ordinary test device, the mobile phone glass cover pressure test device has greatly improved the performance of the entire device while increasing the structure. The improved test device is simpler and more convenient to use, and the original manual inspection operation of the mobile phone glass screen is abandoned. The test data is more accurate, and the pressure of each detection can be kept the same, which effectively meets people's use needs.

[0004] However, the above patent has the following shortcomings: 1. In the above patent, the pressure contact block is driven down by the pressure monitor to perform pressure test on the glass cover of the mobile phone. However, only single-point detection can be performed on the glass cover of the mobile phone, and multi-point detection cannot be performed. Single-point position detection may be affected by local abnormal parts and cannot reflect the overall pressure test situation of the glass cover of the mobile phone, resulting in inaccurate pressure test results. Multi-point sampling can cover a wider range and reduce deviations caused by local characteristics.

[0005] The above-mentioned patent and current mobile phone glass cover testing devices all touch the mobile phone glass cover through pressure contact blocks or test contacts. When the contacts contact the mobile phone glass cover, the pressure is too high, which can easily damage the contacts or the mobile phone glass cover. In addition, the contacts need to be replaced after long-term use, and manual replacement requires stopping the detection, thereby reducing the detection efficiency of the mobile phone glass cover.

[0025] The driving assembly 23 includes a driving motor 1 231 and a driving motor 232 fixedly mounted on the supporting pad 21. The driving motor 1 231 is connected to the adjusting screw 1 221 via a coupling, and the adjusting screw 1 221 is connected to the adjusting screw 222 via a transmission belt 336. A driving shaft 233 is fixedly mounted on the output end of the driving motor 232. A plurality of limit blocks 234 are arranged on the outer wall of the driving shaft 233. The driving shaft 233 is slidably connected to a bevel gear 2 235 via a plurality of limit blocks 234. The bevel gear 235 is meshed with the bevel gear 1 225.

[0026] Among them, the driving motor 1 231 uses a coupling to drive the adjusting screw 1 221 to rotate, and the adjusting screw 1 221 drives the adjusting screw 222 to rotate through a transmission belt 336, so that the adjusting screw 1 221 and the adjusting screw 222 rotate synchronously.

[0027] The fixing mechanism 3 includes a fixing seat 31, which is connected to the driving screw 224 through a sliding nut threaded connection, a bidirectional threaded rod 32 is rotatably installed in the fixing seat 31, a stepping motor 33 is fixedly installed on the outer wall of the fixing seat 31, the stepping motor 33 is transmission-connected to the bidirectional threaded rod 32, two sliding blocks 321 are threadedly connected to the bidirectional threaded rod 32, a supporting seat 34 is fixedly installed on the two sliding blocks 321, and a step groove 341 is provided on the two supporting seats 34, an air guide groove 35 is provided inside the fixing seat 31, and a plurality of air vents 351 are provided on the fixing seat 31, the plurality of air vents 351 are connected to the air guide groove 35, and the plurality of air vents 351 are evenly distributed on the fixing seat 31.

[0028] Furthermore, the stepper motor 33 drives the two-way threaded rod 32 to rotate, and the two sliding blocks 321 drive the two support seats 34 to move horizontally. The two support seats 34 support the mobile phone glass cover through the step groove 341, and the inner wall of the step groove 341 can be pasted with a plastic pad, and the plastic pad is used to support the mobile phone glass cover. When the two-way threaded rod 32 moves forward, the two support seats 34 approach each other, and when the two-way threaded rod 32 moves reversely, the two support seats 34 move away from each other, so that it is suitable for use with different models of mobile phone glass covers, and has a wider range of applications. A negative pressure fan can be installed on the base 1, and the outer wall of the fixed seat 31 can be connected to the negative pressure fan through a joint and an air pipe, so that the air guide groove 35 is connected to the negative pressure fan, and the air guide groove 35 increases the air flow rate between the two support seats 34 through a plurality of vents 351 to form a negative pressure, and fix the mobile phone glass cover on the two support seats 34, thereby driving the stability of the mobile phone glass cover when moving, and preventing it from sliding off the support seat 34 when moving.

[0029] A lifting mechanism 4 is arranged in the support frame 11 and the support frame 2 12, and a testing mechanism 5 for testing the glass cover of the mobile phone is arranged on the lifting mechanism 4, and the lifting mechanism 4 includes a lifting frame 41, and a slider 1 411 and a slider 2 412 are respectively installed at both ends of the lifting frame 41, a guide column 44 slidably connected to the slider 1 411 is fixedly installed in the support frame 1 11, and an elastic slide 43 contacting the guide column 44 is installed on the slider 1 411, a lifting screw 42 is rotatably installed in the support frame 2 12, the slider 2 412 is threadedly connected to the lifting screw 42, and a servo motor 421 is fixedly installed on the top wall of the support frame 2 12, and the servo motor 421 is transmission-connected to the lifting screw 42.

[0030] In addition, the servo motor 421 drives the lifting screw 42 to rotate, thereby using the slider 412 to drive the lifting frame 41 to move longitudinally, which is convenient for adjusting the height of the test mechanism 5. The slider 411 slides on the guide column 44, and two sliding pillars can be installed on the support frame 11. The slider 411 uses a sliding sleeve to slide and connect the two sliding pillars to improve the stability of the lifting frame 41 during longitudinal movement. The controller of this device can be installed on the base 1, and a voltmeter is installed inside the controller. At the same time, a resistance coil can be wound on the guide column 44, and the elastic slide 43 and the bottom wall of the guide column 44 are connected to the circuit. The voltage is detected by the voltmeter. Due to the different sliding heights of the slider 411, its resistance and voltage change, and then the pressure data is detected, and it is judged that the contact 525 is worn, that is, the pressure on the contact 525 is the same, but the voltage changes greatly compared with the previous data, and the contact 525 is worn more and needs to be replaced to prevent the contact 525 from affecting the test accuracy of the mobile phone glass cover due to its own wear.

A magnetic slider 526 that matches the electromagnetic slider 524 is fixedly installed at the upper end of the contact 525. The contact 525 is detachably connected to the electromagnetic slider 524 through the magnetic slider 526. A shock-absorbing spring 523 is mounted on the outer wall of the telescopic rod 522. One end of the shock-absorbing spring 523 abuts against the limit frame 512, and the other end abuts against the electromagnetic slider 524.

[0032] In addition, the limit seat 51 moves longitudinally with the lifting frame 41, and the electromagnetic slider 524 is energized to attract the magnetic slider 526, thereby fixing the contact 525. After the contact 525 descends and contacts the glass cover of the mobile phone, it squeezes the telescopic rod 522, thereby squeezing the shock-absorbing spring 523. The elasticity of the shock-absorbing spring 523 itself is used to reduce the force on the contact 525 and extend the service life of the contact 525. At the same time, the telescopic rod 522 squeezes the pressure sensor 521, and the pressure sensor 521 is used to detect the pressure on the glass cover of the mobile phone.

[0033] The replacement component 53 includes a pneumatic push rod 531, which is fixedly mounted on the outer wall of the limit seat 51.

[0034] Specifically, the contacts 525 are all inserted into the multiple sockets 534 on the rotating disk 533. When the contacts 525 are replaced, the electromagnetic slider 524 is powered off and no longer attracts the magnetic slider 526. The contacts 525 slide into the corresponding sockets 534. The pneumatic push rod 531 drives the stepper motor 2 532 and the rotating disk 533 to descend, so that the contacts 525 are away from the limiting groove 511. The stepper motor 2 532 drives the rotating disk 533 to rotate, so that the new contacts 525 are placed under the limiting groove 511. The pneumatic push rod 531 drives the rotating disk 533 and the contacts 525 to rise, and the electromagnetic slider 524 is powered on to attract the magnetic slider 526, thereby fixing the contacts 525. The contacts 525 on the rotating disk 533 are all movably connected.

The driving motor 232 can drive the driving shaft 233 to rotate. The plurality of limit blocks 234 can be used as pin blocks to drive the bevel gear 235 to rotate, so that the bevel gear 235 and the bevel gear 1 225 are meshed to drive the driving screw 224 to rotate, and the mobile phone glass cover plate moves forward and backward. The driving motor 1 231 and the driving motor 232 can simultaneously drive the adjusting screw rod 1 221 and the driving shaft 233 to rotate, and the bevel gear 235 is on the driving shaft. 233 is moved horizontally and rotated, so that the mobile phone glass cover plate moves along the inclined diagonal line, so as to sample the mobile phone glass cover plate at multiple points. After the mobile phone glass cover plate moves to the corresponding position, the servo motor 421 drives the lifting screw 42 to rotate, so as to use the slider 412 to drive the lifting frame 41 to move longitudinally, so as to adjust the height of the testing mechanism 5, so that the contact 525 contacts the surface of the mobile phone glass cover plate, squeezes the telescopic rod 522, and thus squeezes the shock-absorbing spring 523. The elasticity of the shock-absorbing spring 523 is used to reduce the force on the contact 525 and extend the service life of the contact 525. At the same time, the telescopic rod 522 squeezes the pressure sensor 521, and the pressure sensor 521 is squeezed by the pressure sensor 521. Sensor 521 detects the pressure on the glass cover of the mobile phone. When the contact 525 needs to be replaced, the electromagnetic slider 524 is powered off and no longer attracts the magnetic slider 526. The contact 525 slides into the corresponding socket 534. The pneumatic push rod 531 drives the stepper motor 2 532 and the rotating disk 533 to descend, so that the contact 525 is away from the limit slot 511. The stepper motor 2 532 drives the rotating disk 533 to rotate, so that the new contact 525 is placed under the limit slot 511. The pneumatic push rod 531 drives the rotating disk 533 and the contact 525 to rise, and the electromagnetic slider 524 is powered on to attract the magnetic slider 526, thereby fixing the contact 525 and continuing the detection.
