Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a mobile phone touch control verification device and a verification method for a mobile phone touch display screen. Background Art

[0002] After the mobile phone screen is produced, it needs to undergo touch inspection, which is divided into click test, long press test and slide test. However, the existing detection devices can usually only perform separate click test or slide test, with low versatility. In addition, the click force cannot be adjusted during the test, which affects the accuracy of the detection data.

[0003] To this end, Chinese patent CN115314578B discloses a mobile phone screen line and click detection device, which realizes the click detection of the mobile phone screen by driving the extension and contraction of the cylinder piston rod, and realizes the line detection of the mobile phone screen by driving the movable frame to move by the driving motor, so that it has the functions of both click detection and line detection. And by setting a height adjustment mechanism, the height of the detection pen can be adjusted before the mobile phone screen is detected, and then the pressure during the line and click test can be adjusted.

[0004] However, when performing sliding detection on the display screen, if the detection pen is always in a vertical state, the contact area between the pen tip and the display screen is small. When sliding quickly, the contact between the pen tip and the display screen is not stable enough, resulting in fluctuations in the detection signal and affecting the detection accuracy. In addition, during the actual use of the mobile phone, the operator's fingertips are usually in a tilted state during the sliding operation. Therefore, the detection pen that is always kept in a vertical state cannot simulate the actual use process, affecting the detection accuracy. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention solves the problem that the detection pen of the existing touch test device cannot be tilted and affects the accuracy of the sliding test data through a workbench, a mechanical arm and an angle adjustment mechanism, and controls the tilt of the detection pen through a torsion spring and an angle adjustment mechanism to improve the fidelity of the touch simulation, thereby improving the detection accuracy of the touch detection and avoiding the occurrence of jump points and intermittent situations of the detection pen during the sliding process. When performing a sliding test, the tip of the detection pen is first brought into contact with the sliding start end on the display screen, and then the detection pen is moved by the mechanical arm. The detection pen is subjected to the action of friction and downward pressure, overcomes the elastic force of the torsion spring and drives the bracket to rotate along the main axis. As the detection pen tilts, the mechanical arm controls the bracket to continue to move downward, and through the signal fed back by the pressure sensor, keeps the downward pressure of the detection pen on the display screen constant. After the detection pen tilts, the angle adjustment mechanism controls the main axis to rotate to a specified angle, and the main axis pulls the bracket to rotate through the torsion spring. The bracket and the detection pen are controlled to move by the mechanical arm, and a sliding operation is performed on the display screen, and the sliding touch is detected according to the feedback of the mobile phone.

[0022] 2.

The rotation of the adjustment disk is controlled by the cooperation of the control component and the limiting disk. The rotation timing of the main shaft is controlled by the adjustment disk. When the detection pen is tilted, the detection pen drives the control component to control the separation of the limiting disk and the adjustment disk, thereby releasing the rotation restriction of the adjusting disk, and then the main shaft and the adjustment disk are driven to rotate by the second rotation driver.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figure 1-Figure 3: A mobile phone touch verification device comprises a workbench 1 and a mechanical arm 2, the workbench 1 is arranged on a movable slide with a guide rail, the mechanical arm 2 is arranged on the side of the movable slide, and a mounting plate 21 is arranged at the end of the mechanical arm 2, a main shaft 211 is rotatably arranged on the mounting plate 21, a bracket 22 is sleeved on the main shaft 211, the bracket 22 is connected to the main shaft 211 through a torsion spring, a detection pen 221 is installed on the bracket 22, and an angle adjustment mechanism 3 for controlling the rotation of the main shaft 211 is arranged on the mounting plate 21. In a working state, when the tip of the detection pen 221 contacts the screen of a mobile phone 5 and generates pressure, the detection pen 221 is subjected to a reaction force and overcomes the elastic force of the torsion spring to drive the bracket 22 to rotate along the main shaft 211, and then the angle adjustment mechanism 3 controls the main shaft 211 to rotate to a specified angle, the main shaft 211 pulls the bracket 22 to rotate through the torsion spring, and after the detection is completed, the angle adjustment mechanism 3 controls the main shaft 211 to reset, and the bracket 22 drives the detection pen 221 to reset under the elastic force of the torsion spring.

[0038] The movable slide is provided with a screw structure for controlling the workbench 1 to move along the guide rail, and two push bars 11 and a linear drive component 12 for controlling the movement of the two push bars 11 are slidably installed on the workbench 1, and the linear drive component 12 includes a first rotary driver 121 and a screw 122, the first rotary driver 121 is arranged on the workbench 1, the screw 122 is rotatably arranged on the workbench 1, the screw 122 is transmission-connected with the driving end of the first rotary driver 121, and the screw 122 is provided with two threaded sections with opposite thread directions, the two threaded sections are respectively threadedly connected with the two push bars 11, and then the two push bars 11 are driven by the first rotary driver 121 to move in opposite directions at the same speed. After the mobile phone 5 is placed on the workbench 1, the two push bars 11 are controlled to move toward the mobile phone 5 by the first rotary driver 121, and then the mobile phone 5 is fixed and positioned by the two push bars 11 respectively abutting against the two sides of the mobile phone 5, and a pressure sensor for sensing the pressure under the detection pen 221 is provided at the connection between the mechanical arm 2 and the mounting plate 21. After the mobile phone 5 is fixed to the middle position of the workbench 1 by the push bar 11 and the linear drive assembly 12, the bracket 22 is moved to the top of the screen of the mobile phone 5 by the robotic arm 2, and then the tip of the detection pen 221 is controlled by the robotic arm 2 to contact the test position of the display screen to perform a click test. When performing a sliding test, first, the tip of the detection pen 221 is brought into contact with the sliding starting end on the display screen, and then the detection pen 221 is moved by the mechanical arm 2. Under the action of friction and downward pressure, the detection pen 221 overcomes the elastic force of the torsion spring and drives the bracket 22 to rotate along the main shaft 211. As the detection pen 221 tilts, the mechanical arm 2 controls the bracket 22 to continue to move downward, and through the signal fed back by the pressure sensor, keeps the downward pressure of the detection pen 221 on the display screen constant. After the detection pen 221 tilts, the angle adjustment mechanism 3 controls the main shaft 211 to rotate to a specified angle. The main shaft 211 pulls the bracket 22 to rotate through the torsion spring. The bracket 22 and the detection pen 221 are controlled to move by the mechanical arm 2 to perform a sliding operation on the display screen, and the sliding touch is detected according to the feedback of the mobile phone 5, thereby completing the touch detection of the display screen of the mobile phone 5. After the detection is completed, the angle adjustment mechanism 3 controls the main shaft 211 to reset, and the bracket 22 drives the detection pen 221 to reset under the elastic force of the torsion spring.

[0039] Reference Figure 3-Figure 5The angle adjustment mechanism 3 includes an adjusting disk 31, a limiting disk 32, a control component 33 and a second rotation driver 34; the adjusting disk 31 is sleeved on the main shaft 211, and the limiting disk 32 is slidably sleeved on the main shaft 211. When the limiting disk 32 abuts against the adjusting disk 31, the adjusting disk 31 is restricted from rotating. A connecting rod 321 and a first elastic member 322 are provided on the limiting disk 32. The connecting rod 321 slides with the mounting disk 21. The two ends of the first elastic member 322 are respectively connected to the limiting disk 32 and the mounting disk 21. The control component 33 is used to overcome the elastic force of the first elastic member 322 to control the limiting disk 32 to move in a direction away from the adjusting disk 31. The second rotation driver 34 is arranged on the mounting disk 21, and the second rotation driver 34 is used to drive the main shaft 211 to rotate.

[0040] The present invention realizes the function of adjusting the tilt angle of the detection pen 221 through the adjustment disk 31, the limiting disk 32, the control component 33 and the second rotation driver 34, and utilizes the cooperation of the control component 33 and the limiting disk 32 to achieve the effect of controlling the rotation of the adjustment disk 31. The second rotation driver 34 is preferably a servo motor without self-locking capability; when performing a sliding test on the display screen of the mobile phone 5, the tip of the detection pen 221 is first brought into contact with the sliding start end on the display screen through the mechanical arm 2, and then the detection pen 221 is moved through the mechanical arm 2. The detection pen 221 is subjected to the effects of friction and downward pressure, overcomes the elastic force of the torsion spring and drives the bracket 22 to rotate along the main axis 211. As the detection pen 221 tilts, the mechanical arm 2 controls the bracket 22 to continue to move downward, and maintains the downward pressure of the detection pen 221 on the display screen through the signal fed back by the pressure sensor. The control component 33 is driven by the squeezing effect of the detection pen 221 after the detection pen 221 is tilted. The control component 33 overcomes the elastic force of the first elastic member 322 to drive the limiting disk 32 to move in the direction away from the adjusting disk 31, so that the limiting disk 32 is separated from the adjusting disk 31, and the rotation restriction of the limiting disk 32 on the adjusting disk 31 is released. Then, the main shaft 211 is driven to rotate to a specified angle through the second rotation driver 34. The main shaft 211 pulls the bracket 22 to rotate through the torsion spring, and controls the movement of the bracket 22 and the detection pen 221 through the robot arm 2 to perform a sliding operation on the display screen.

[0041] Reference Figure 4 , Figure 6 and Figure 7 : A docking block 323 and a second elastic member 324 are provided on the limiting disk 32, and the docking block 323 is slidably installed on the limiting disk 32. The two ends of the second elastic member 324 are respectively connected to the docking block 323 and the limiting disk 32. A docking groove 311 that cooperates with the docking block 323 is provided on the adjusting disk 31. When the docking block 323 and the docking groove 311 are plugged into each other, the limiting disk 32 limits the rotation of the adjusting disk 31.

[0042] The present invention realizes the function of limiting the rotation of the regulating disk 31 when the limiting disk 32 is close to the regulating disk 31 through the docking block 323 , the second elastic member 324 and the docking groove 311 . The limiting disk 32 is provided with a receiving groove for accommodating the docking block 323. When the limiting disk 32 is close to the adjusting disk 31 and the gap between the limiting disk 32 and the adjusting disk 31 is less than a threshold value, the docking block 323 is squeezed by the adjusting disk 31, and the elastic force of the second elastic member 324 is overcome to push the docking block 323 into the receiving groove. The bracket 22 pulls the main shaft 211 to rotate through the torsion spring, and the main shaft 211 drives the adjusting disk 31 to rotate. When the adjusting disk 31 and the limiting disk 32 rotate relative to each other, as the adjusting disk 31 rotates, when the docking groove 311 on the adjusting disk 31 is aligned with the docking block 323, the docking block 323 is engaged with the docking groove 311 under the elastic force of the second elastic member 324. The more the number of docking grooves 311 is, the smaller the required rotation angle is, and the further rotation of the adjusting disk 31 and the main shaft 211 is limited by the limiting disk 32. When the detection pen 221 is tilted by the reaction force of the display screen, the detection pen 221 drives the bracket 22 to rotate. The rotation of the bracket 22 drives the control component 33 through the squeezing force of the bracket 22. The control component 33 drives the limiting disk 32 to move, overcomes the elastic force of the first elastic member 322, and drives the limiting disk 32 to move in a direction away from the adjusting disk 31, so that the limiting disk 32 is separated from the adjusting disk 31, and the limiting disk 32 drives the docking block 323 to move. When the docking block 323 is separated from the docking groove 311, the limiting disk 32 releases the adjusting disk 31. The rotation of the disk 31 is limited, and then the second rotation driver 34 is used to drive the main shaft 211 to rotate. The main shaft 211 drives the adjusting disk 31 to rotate. At the same time, as the main shaft 211 rotates, the elastic force of the torsion spring is released, and when the rotation angle of the main shaft 211 exceeds the bracket 22 and the detection pen 221, the main shaft 211 pulls the bracket 22 and the detection pen 221 through the torsion spring, thereby driving the detection pen 221 to rotate. After the detection pen 221 is controlled to rotate to a specified angle, the detection pen 221 is driven to move through the robot arm 2 and slide on the display screen to perform a sliding test.

[0043] Reference Figure 8-Figure 10The control component 33 includes a movable block 331, a third elastic member 332 and a connecting disk 333. The movable block 331 is slidably mounted on the adjusting disk 31. An extension block 3311 is provided on the movable block 331. Two ends of the third elastic member 332 are respectively connected to the movable block 331 and the adjusting disk 31. The movable block 331 abuts against the limiting disk 32 under the elastic force of the third elastic member 332, and an arc surface is provided at the end of the plane section of the extension block 3311. In the working state, when the detection pen 221 tilts under the squeezing force of the display screen, the detection pen 221 overcomes the elastic force of the torsion spring to drive the bracket 22 to rotate. The bracket 22 squeezes the arc surface of the extension block 3311, overcomes the elastic force of the third elastic member 332 to drive the movable block 331 to move in the direction close to the limiting disk 32. The movable block 331 overcomes the elastic force of the first elastic member 322 to push the limiting disk 32 to move, and the limiting disk 32 releases the rotation restriction on the adjusting disk 31.

[0044] The present invention realizes the function of controlling the limiting disk 32 to release the rotation restriction of the adjusting disk 31 through the movable block 331, the extension block 3311, the third elastic member 332 and the connecting disk 333. The bracket 22 is provided with a connecting disk 333, and the connecting disk 333 is provided with a notch for the extension block 3311 of the movable block 331 to extend out. When performing a sliding test, the detection pen 221 is moved to the collected display screen by the mechanical arm 2. When the tip of the detection pen 221 contacts the display screen, under the downward pressure provided by the mechanical arm 2, the detection pen 221 is driven by the reaction force of the display screen, overcomes the elastic force of the torsion spring and tilts, and the detection pen 221 drives the bracket 22 to rotate. The notch of the connecting disk 333 on the bracket 22 is misaligned with the extension block 3311. The connecting disk 333 on the bracket 22 squeezes the arc segment of the extension block 3311, overcomes the elastic force of the third elastic member 332 and pushes the movable block 331, and then the limiting disk 32 is pushed to move by the movable block 331, so that the docking block 323 on the limiting disk 32 is separated from the docking groove 311 on the adjusting disk 31, and the rotation restriction of the limiting disk 32 on the adjusting disk 31 is released.

[0045] Reference Figure 3-Figure 5 : An auxiliary control mechanism 4 is provided on the adjusting disk 31, and the auxiliary control mechanism 4 includes a first mounting ring 41, an articulated seat 42 and a fourth elastic member 43. The first mounting ring 41 is fixedly sleeved on the detection pen 221, and a fixed shaft 411 is provided on the first mounting ring 41. There are two articulated seats 42, and the two articulated seats 42 are respectively rotatably set on the adjusting disk 31 and the fixed shaft 411, and the two ends of the fourth elastic member 43 are respectively connected to the two articulated seats 42.

[0046] The present invention realizes the function of pushing the detection pen 221 to rotate when the detection pen 221 is tilted through the first mounting ring 41, the fixed shaft 411, the hinge seat 42 and the fourth elastic member 43. When the detection pen 221 is tilted by the reaction force of the display screen, the bracket 22 squeezes the extension block 3311 on the movable block 331, overcomes the elastic force of the third elastic member 332 to drive the movable block 331 to move in the direction close to the limiting disk 32, and then overcomes the elastic force of the first elastic member 322 to push the limiting disk 32 to move, and releases the rotation restriction of the limiting disk 32 on the adjustment disk 31. When the detection pen 221 is tilted, the detection pen 221 drives the first mounting ring 41 and the hinge seat 42 installed on the first mounting ring 41 to rotate, and the elastic force of the fourth elastic member 43 is released to push the first mounting ring 41, so that the first mounting ring 41 and the detection pen 221 further rotate, and the bracket 22 and the detection pen 221 are controlled to tilt. When the detection pen 221 is in a vertical state relative to the mounting plate 21, the fourth elastic member 43 is in a compressed state, and the axis of the fourth elastic member 43 is parallel to the axis of the detection pen 221. At this time, the hinged seat 42 is pushed by the elastic force of the fourth elastic member 43, and the first mounting ring 41 is fixedly connected to the detection pen 221 and cannot move along the axis of the detection pen 221. Therefore, the fourth elastic member 43 cannot drive the first mounting ring 41 to move by pushing the fixed shaft 411. The two hinged seats 42 and the fourth elastic member 43 are in a balanced state. Once the detection pen 221 and the bracket 22 tilt, the balanced state is broken, and the fourth elastic member 43 releases elastic potential energy, and drives the detection pen 221 to rotate by pushing the hinged seat 42 on the fixed shaft 411, thereby controlling the rotation of the detection pen 221 and the bracket 22, and controlling the tilt of the detection pen 221.

[0047] Reference Figure 3-Figure 5 A limit frame 44 for limiting the rotation angle of the detection pen 221 is provided on the mounting plate 21, and a telescopic rod 45 is provided on the hinge seat 42, and both ends of the telescopic rod 45 are respectively connected to the two hinge seats 42.

[0048] The present invention realizes the function of limiting the rotation angle of the detection pen 221 through the limit frame 44 and the telescopic rod 45, so as to achieve the effect of controlling the tilt angle of the detection pen 221. When the detection pen 221 tilts, the elastic force of the fourth elastic member 43 overcomes the elastic force of the torsion spring to control the detection pen 221 and the bracket 22 to rotate further, until the first mounting ring 41 and the fixed shaft 411 abut against the limit frame 44, hindering the further rotation of the detection pen 221, thereby controlling the tilt range of the detection pen 221. After the detection is completed, the main shaft 211 is driven to rotate by the second rotary driver 34, and the main shaft 211 drives the adjustment disk 31 to rotate. During this process, the detection pen 221 is restricted by the limit frame 44 and cannot rotate further. The fourth elastic member 43 is continuously compressed, and the torsion spring is gradually reset and releases elastic potential energy. When the main shaft 211 is reset relative to the bracket 22, the torsion spring is in a natural state, and the extension block 3311 on the movable block 331 moves to the notch of the connecting disk 333 again. The movable block 331 is in the third elastic member 33 2, the extension block 3311 is driven to move under the elastic force of the fourth elastic member 43, and the extension block 3311 is controlled to extend. The fourth elastic member 43 and the two hinge seats 42 are in a balanced state again, and then the main shaft 211 is controlled to rotate by the second rotation driver 34. At this time, since the fourth elastic member 43 is in a balanced state, the rotation of the main shaft 211 will drive the adjustment disk 31 to rotate, and since the fourth elastic member 43 will not deflect, the main shaft 211 pulls the bracket 22 and the detection pen 221 to rotate synchronously through the torsion spring, completing the reset action of the detection pen 221.

[0049] Reference Figure 3 and Fig.11 A linear driver 46 is provided on the mounting disk 21, and a push rod 461 is provided at the driving end of the linear driver 46. In the working state, when the linear driver 46 drives the push rod 461 to extend, the push rod 461 squeezes the movable block 331, overcomes the elastic force of the third elastic member 332 and drives the movable block 331 to slide, and the movable block 331 drives the extension block 3311 to move, so that the plane section on the extension block 3311 abuts against the connecting disk 333, thereby limiting the rotation of the connecting disk 333.

[0050] The present invention realizes the function of actively limiting the rotation of the bracket 22 through the linear driver 46 and the push rod 461 . When controlling the bracket 22 and the detection pen 221 to reset, it is necessary to keep the fourth elastic member 43 in the reset state. Once the detection pen 221 is subjected to external force, such as when the detection pen 221 contacts and collides with other objects during the reset process, the balance state of the fourth elastic member 43 will be broken, and the elastic force of the fourth elastic member 43 pushes the first mounting ring 41, thereby pushing the bracket 22 to rotate, thereby affecting the reset of the detection pen 221. For this purpose, a linear drive 46 and a push rod 461 are provided. When the second rotation drive 34 drives the main shaft 211 to rotate, so that the fixed shaft 411 abuts against the limit frame 44, and the torsion spring is in a natural state and the fourth elastic member 43 is in a balanced state, the extension block 3311 on the movable block 331 extends out from the notch of the connecting disk 333 again. At this time, the push rod 461 is driven to extend through the linear drive 46, and the push rod 461 overcomes the elastic force of the third elastic member 332 to squeeze the movable block 331, thereby pushing the movable block 331 and the extension block 33 11, so that the flat section of the extension block 3311 abuts against the notch side wall of the connecting disk 333. At this time, when the detection pen 221 is subjected to the reaction force of the display screen or other forces, the connecting disk 333 cannot squeeze the arc surface of the extension block 3311, and the rotation of the bracket 22 is limited by the abutment between the flat section of the extension block 3311 and the notch side wall of the connecting disk 333, so as to avoid the balance state of the fourth elastic member 43 being broken, thereby stably controlling the reset of the detection pen 221 and the bracket 22 to facilitate subsequent sliding tests, and after completing the reset of the detection pen 221, when the sliding test is performed again, the linear drive 46 controls the push rod 461 to reset, so that when the detection pen 221 tilts, it can be controlled by the fourth elastic member 43 to automatically tilt to the limit frame 44, and perform an active tilting operation, and the tilting direction of the active tilting is the same as the tilting direction of the detection pen 221, and when the detection pen 221 is squeezed in the corresponding direction, it can automatically tilt in the corresponding direction.

[0051] Reference Figure 1 , Figure 4 and Figure 5 : A buffer assembly 23 is provided on the bracket 22, and the buffer assembly 23 includes a second mounting ring 231 and a fifth elastic member 232. The second mounting ring 231 is sleeved on the detection pen 221, and the two ends of the fifth elastic member 232 are respectively connected to the second mounting ring 231 and the bracket 22.

[0052] The present invention realizes the function of preventing the detection pen 221 from exerting excessive downward pressure on the display screen when the detection pen 221 is pressed down by the second mounting ring 231 and the fifth elastic member 232. When the mechanical arm 2 controls the detection pen 221 to press down, the tip of the detection pen 221 will contact the display screen first. Since the contact area between the tip of the pen and the display screen is small, when the downward pressure is too large, it is easy to cause damage to the display screen. For this reason, a buffer component 23 is provided. When the display screen is pressed down, the fifth elastic member 232 is compressed under the reaction force, thereby preventing the tip of the detection pen 221 from exerting rigid extrusion on the display screen. Through the buffering effect of the fifth elastic member 232, the downward pressure of the detection pen 221 can be adjusted more conveniently. Moreover, when the detection pen 221 is tilted, the distance between the bracket 22 and the display screen will change. At this time, the mechanical arm 2 continues to press down, and the downward pressure of the detection pen 221 on the display screen will fluctuate greatly, and it is easy to have a situation where the downward pressure distance is too large. Through the deformation effect of the fifth elastic member 232, the situation where parts are damaged can be avoided to a great extent.

[0053] Reference Figure 1 , Figure 4 and Figure 5 : A guide rod 233 is provided on the second mounting ring 231 , and the guide rod 233 is slidably matched with the bracket 22 . Two limit rings 2331 are provided on the guide rod 233 , and the bracket 22 is located between the two limit rings 2331 .

[0054] The present invention realizes the function of limiting the moving range of the bracket 22 relative to the second mounting ring 231 through the guide rod 233 and the limit ring 2331. Through the guiding effect of the guide rod 233, the second mounting ring 231 can be prevented from being subjected to a large radial torque, thereby preventing the detection pen 221 and the second mounting ring 231 from being damaged when the detection pen 221 is tilted. At the same time, the two limit rings 2331 on the guide rod 233 limit the moving range of the detection pen 221 relative to the bracket 22, thereby preventing the detection pen 221 from being excessively displaced, thereby preventing the fifth elastic member 232 from being plastically deformed.
