Description

Technical Field

[0001] The invention relates to the technical field of mobile phone detection, in particular to a detection device used for mobile phone processing. Background Art

[0002] Mobile phone screens are also called display screens, which are used to display images and colors. Screen material As mobile phone color screens become more and more popular, the material of mobile phone screens is becoming more and more important; the application of mobile phone screens has transitioned from resistive screens to capacitive screens, and touch operations have become more sensitive, with stronger human-computer interaction. Compared with resistive mobile phone screens, capacitive mobile phone screens have better performance. As long as the finger touches the screen, it can be sensed and recognized. Even if it is in contact for a long time, the mobile phone screen will not be worn out, and it is convenient and natural to use. The capacitive mobile phone screen is composed of a PCB with a highly integrated chip, with fewer components, better consistency, and a high yield rate. The yield rate of mobile phone screens is determined by the final test results. The mobile phone touch screen test is to detect defective products. All mobile phone screens that do not meet the performance and quality standards cannot flow into the next production station to avoid loss of production resources.

[0003] Mobile phone screen testing includes screen power-on and capacitive touch testing. After the conveyor belt transfers the mobile phone screen to the testing area, workers gather around the testing table in the testing area. In order to reduce the number of times the mobile phone screen is taken and improve the testing efficiency of the mobile phone screen, workers will stack the mobile phone screens together and place the stacked mobile phone screens on the testing table. Then, the mobile phone screens will be tested from top to bottom. The workers will connect the end of the touch screen cable connected to the mobile phone screen to the detector. In order to ensure the power-on stability of the mobile phone screen, the workers will press one of their hands on the connection position between the touch screen cable and the detector, and the workers will control the other hand on the stacked hands. When performing touch detection on the screen of a mobile phone, since the screen of the mobile phone is relatively thin, the screen may shift when the worker touches it. The shifted screen may cause the touch screen cable to be pulled. The touch screen cable is very delicate and fragile. Therefore, it is easy to cause the touch screen cable to be pulled and damaged during the displacement process of the screen scratch detection, thereby damaging the screen detection. The method of directly picking up the stacked mobile phone screens for scratch detection, on the one hand, if the connection position of the touch screen cable and the connector is not pressed, it will cause poor connection. On the other hand, the worker's hands will become sore after holding the mobile phone screen for a long time. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0030] Embodiment 1: A detection device for mobile phone processing, comprising a detection platform 1 and a detector 2 arranged on the detection platform 1; the detector 2 is provided with a contact 21 connected to the end of the touch screen cable on the mobile phone screen; a positioning seat 3 is provided on the front side of the detection platform 1; a suction cup 31 is provided on the lower surface of the positioning seat 3; a positioning groove 32 is provided on the upper surface of the positioning seat 3; the inner wall of the positioning groove 32 is slidably connected to the support plate 4; the inner cross-section of the positioning groove 32 is adapted to the shape of the mobile phone screen; a pressure spring 41 is provided on the lower surface of the support plate 4; the pressure spring 41 drives the support plate 4 to move upward as the gravity above the support plate 4 decreases; an operating groove 33 is provided at the corner position of the positioning seat 3 close to the detector 2; the operating groove 33 is connected to the positioning groove 32; the touch screen cable on the mobile phone screen extends out of the operating groove 33.

[0031] In this embodiment, a groove 42 is provided on the outer wall of the support plate 4; a clamping block 5 is slidably connected in the groove 42; the clamping block 5 is connected to the bottom of the groove 42 via a clamping spring 51; a guide surface 52 is provided on the end of the clamping block 5 away from the clamping spring 51 and tilted upward; clamping grooves 34 are vertically and evenly provided on the inner wall of the positioning groove 32; the grooves 42 correspond one-to-one with the clamping grooves 34 after the support plate 4 moves; the end of the clamping block 5 away from the clamping spring 51 can be clamped into the clamping groove 34.

[0032] In this embodiment, the bottom of the slot 34 passes horizontally through the inner and outer walls of the positioning seat 3; the end of the block 5 away from the clamping spring 51 can be inserted into the inner port of the slot 34; the outer port of the slot 34 is slidably connected to the unlocking block 35; the specifications of the unlocking block 35 are adapted to the shape of the slot 34; and multiple unlocking blocks 35 are jointly fixedly connected to the unlocking bar 36.

[0033] After the mobile phone screen assembly is assembled, the mobile phone screen assembly will be transported to the inspection area along the conveyor belt, and then the staff will stack the single mobile phone screen assemblies together, place the positioning seat 3 on the front side of the detector 2, and use the suction cup 31 on the lower surface of the positioning seat 3 to fix the positioning seat 3 on the upper surface of the inspection table 1, and then place the stacked mobile phone screens on the upper surface of the support plate 4. Since the card block 5 is stuck in the corresponding card slot 34, after the stacked mobile phone screens are placed on the support plate 4, even if the gravity on the upper surface of the support plate 4 increases, the support plate 4 cannot move down, and then the staff will press the unlocking bar 36 to approach the positioning seat 3. The unlocking bar 36 will be pressed to drive the unlocking block 35 to slide in the card slot 34, and multiple unlocking blocks 35 will move close to the center of the positioning slot 32, and multiple unlocking blocks 35 will fill the corresponding card slot 34, thereby squeezing out the card block 5 in the corresponding card slot 34. After being squeezed out by the unlocking block 35, the card block 5 will overcome the clamping spring 51 and retract into the groove 42 for avoidance, so that the support plate 4 is unlocked inside the positioning slot 32;

[0034] The stacked mobile phone screens placed on the support plate 4 will transfer gravity to the support plate 4, and the support plate 4 will move downward after being unlocked, and the support plate 4 will not cause a large vibration under the buffering of the pressure spring 41, so that the stacked mobile phone screens will move down smoothly with the support plate 4 and enter the positioning groove 32. The upper end of the positioning groove 32 is provided with a chamfer, so that the stacked mobile phone screens can enter the positioning groove 32 more smoothly under the guidance of the chamfer. The touch screen cable on the mobile phone screen faces the detector 2 and extends from the operating groove 33. The distance between the detector 2 and the positioning seat 3 is less than the length of the touch screen cable. After the support plate 4 moves down to the limit position, the pressing of the unlocking strip 36 is stopped, and the card block 5 in the groove 42 is inserted into the corresponding card slot 34 under the elastic force of the clamping spring 51, and the unlocking block 35 is squeezed open in the card slot 34, so that the support plate 4 is unidirectionally locked in the positioning groove 3 2, the top mobile phone screen in the positioning groove 32 is close to the notch of the positioning groove 32 but not higher than the notch of the positioning groove 32, so as to ensure the positioning effect of the positioning groove 32 on the mobile phone screen. Then, when the detector 2 is powered on, one hand is used to control the end of the touch screen cable to contact the contact 21 on the detector 2, so that the mobile phone screen and the detector 2 are electrically connected. Then, the detection button on the detector 2 is pressed to observe the power-on status of the mobile phone screen. In addition, the other hand is controlled to slide on the surface of the mobile phone screen after power-on through the operation groove 33 to observe the scribing effect on the mobile phone screen, so as to realize the screen scribing touch detection. In the process of scribing the surface of the mobile phone screen, since the surrounding of the mobile phone screen is positioned by the positioning groove 32, the mobile phone screen will not shift, so as to ensure the stability of the mobile phone screen and avoid the situation that the touch screen cable is pulled and damaged due to the displacement of the mobile phone screen;

[0035] In addition, when the staff slides on the mobile phone screen, the mobile phone screen will be subjected to a downward pressure. However, since the support plate 4 and the positioning groove 32 are one-way locked, the support plate 4 will not move down during the mobile phone screen detection process, making the mobile phone screen detection more stable. After completing the detection, the staff controls one of their hands to loosen the connection between the end of the touch screen cable and the contact 21 on the detector 2, and the staff will open the top mobile phone screen of the stacked mobile phone screens through the operating groove 33, so that the mobile phone screen is taken out from the inner side of the positioning groove 32. As the number of mobile phone screens above the support plate 4 decreases, the pressure spring 4 1 is reduced, so that the pressure spring 41 drives the support plate 4 to move upward, and the upward movement of the support plate 4 drives the card block 5 to move upward. As the support plate 4 moves upward, the guide surface 52 on the card block 5 is squeezed by the corresponding card slot 34, so that the card block 5 is compressed to overcome the clamping spring 51 and retract into the groove 42 to avoid it. After the support plate 4 stops moving upward, the card block 5 is clamped into the corresponding card slot 34 under the elastic force of the clamping spring 51, so that the support plate 4 is locked again, and then the touch screen cable connected to the mobile phone screen to be detected is controlled to contact with the contact point 21 of the detector 2, and the above actions are repeated;

[0036] The present invention places the stacked mobile phone screens into the positioning groove 32 and cooperates with the movable support plate 4 in the positioning groove 32, so that the mobile phone screens will not shift during the detection process, thereby avoiding the touch screen cable connected to the mobile phone screen from being pulled and damaged, thereby reducing the damage rate of the mobile phone screen after detection.

[0037] Embodiment 2: Adjustment strips 6 are provided on the four directions of the inner wall of the positioning groove 32; the two adjustment strips 6 close to the operating groove 33 are slidably connected to the bottom of the positioning groove 32 at the lower end; the four edges of the support plate 4 are provided with first avoidance grooves 43 for the adjustment strips 6 to avoid; a threaded hole 37 is penetrated through the inner wall of the positioning groove 32 close to the operating groove 33; the threaded hole 37 is threadedly connected to the first bolt 38; the first bolt 38 is rotatably connected to the corresponding adjustment strip 6.

[0038] In this embodiment, a belt groove 61 is provided on one side of the adjustment strip 6 close to the center of the positioning groove 32; a roller 62 is rotatably connected inside the belt groove 61; the roller 62 inside the belt groove 61 is transmission-connected to a belt 63; the belt 63 extends out of the belt groove 61 and contacts the edge of the mobile phone screen on the support plate 4.

[0039] In this embodiment, the outer wall of the belt 63 is evenly provided with elastic protrusions 64 along the transmission direction; the distance between adjacent elastic protrusions 64 is adapted to the thickness of a single mobile phone screen; the elastic protrusions 64 on the two opposite belts 63 are staggered in the vertical direction; the end of the lowest roller 62 in the belt groove 61 is fixedly connected to the eccentric block 65; the support plate 4 is provided with a notch 44 near the operating groove 33.

[0040] Before the stacked mobile phone screens are placed inside the positioning groove 32, a single mobile phone screen sample is first placed on the upper surface of the support plate 4, and then the two first bolts 38 close to the operating groove 33 are screwed. The first bolts 38 will drive the two adjustment bars 6 close to the operating groove 33 to slide along the bottom of the positioning groove 32 when being screwed. The adjustment bar 6 close to the operating groove 33 moves close to the center of the positioning groove 32 when the first bolts 38 are screwed. The adjustment bar 6 close to the operating groove 33 will enter the corresponding first avoidance groove 43 for avoidance. The two adjustment bars 6 close to the operating groove 33 will push the mobile phone screen sample on the support plate 4, so that the belts 63 on the four adjustment bars 6 are in contact with the sample, and the control adjustment in the positioning groove 32 is completed. In this way, the positioning groove 32 in the positioning seat 3 can be suitable for mobile phone screens of different specifications, thereby improving the applicable range of the positioning groove 32 and improving the detection range of the detection device. After completing the adjustment of the adjustment bar 6, the mobile phone screen sample is removed from the support plate 4;

[0041] Since the end of the lowest roller 62 in each belt groove 61 is fixedly connected to the eccentric block 65, when no mobile phone screen is placed in the positioning groove 32, the center of gravity of the eccentric block 65 is located below the corresponding roller 62, so that the elastic protrusion 64 on the elastic belt 63 can be transmitted to a suitable position to maintain stability, so that the elastic protrusions 64 on the two opposite belts 63 are staggered in the vertical direction. After the stacked mobile phone screens are placed on the upper surface of the support plate 4, the support plate 4 is pressed to overcome the elastic force of the pressure spring 41 and move downward. During the downward movement of the support plate 4, the stacked mobile phone screens will be driven to move downward. During the downward movement of the stacked mobile phone screens, they will enter the side of the multiple adjustment strips 6 close to the center of the positioning groove 32. As the support plate 4 moves downward, the stacked mobile phone screens will contact the belts 63 in four directions, and the belts 63 will contact the edges of the mobile phone screens to form static friction.

[0042] The belt 63 is driven as the stacked mobile phone screens move downward, and the belt 63 is driven in the corresponding belt groove 61. During the transmission process of the belt 63, the elastic protrusion 64 on the outer surface is driven to drive synchronously. Since the elastic protrusions 64 on the two relative belts 63 are staggered in the vertical direction, the elastic protrusions 64 on the two belts 63 in the relative direction squeeze the edges of the stacked mobile phone screens, which will cause the stacked mobile phone screens to be slightly staggered in the front-to-back direction and the left-to-right direction. The elastic protrusion 64 is hemispherical, so that the stacked mobile phone screens are slightly staggered in the vertical direction. In the subsequent detection process, the slightly misaligned mobile phone screens are still kept in the positioning groove 32 and limited by the belts 63 in four directions. After completing the detection of the mobile phone screens, since the stacked mobile phone screens are slightly misaligned up and down, it is easier for the staff's fingers to remove the top mobile phone screen of the stacked mobile phone screens, thereby improving the removal efficiency of the mobile phone screens and facilitating the detection of the mobile phone screens.

[0043] As the number of mobile phone screens on the pallet 4 decreases, the pallet 4 will drive the remaining stacked mobile phone screens to move upward. During the upward movement of the stacked mobile phone screens, static friction is generated between the belt 63 at the edge, so that the belt 63 is driven as the stacked mobile phone screens move upward. In this way, the stacked mobile phone screens can avoid wear on the edges of the mobile phone screens during vertical movement in the placement grooves, thereby achieving the purpose of protecting the mobile phone screens during the inspection process. For the last mobile phone screen on the pallet 4, the staff can remove the last mobile phone screen through the notch 44.

[0044] Embodiment 3: The inner wall of the positioning groove 32 is slidingly connected to the adjustment plate 7; the adjustment plate 7 is located directly below the support plate 4; the four sides of the adjustment plate 7 are provided with second avoidance grooves 71; the second avoidance grooves 71 correspond to the corresponding adjustment strips 6; the pressure spring 41 is located between the support plate 4 and the adjustment plate 7; one end of the pressure spring 41 is connected to the support plate 4, and the other end is connected to the adjustment plate 7; the lower surface of the positioning seat 3 is provided with a third avoidance groove 39; the third avoidance groove 39 passes through the upper and lower parts and is threadedly connected to the second bolt 8; the upper end of the second bolt 8 is rotatably connected to the lower surface of the adjustment plate 7.

[0045] In this embodiment, an anti-slip groove 321 is vertically arranged on the inner wall of the positioning groove 32; an anti-slip block 322 is slidably connected to the anti-slip groove 321; the anti-slip block 322 is fixedly connected to the support plate 4; the upper end of the anti-slip groove 321 is close to the upper surface of the positioning seat 3, and the lower end is close to the bottom of the positioning groove 32.

[0046] Different batches of mobile phone screens have different qualities. In order to ensure that the stacked mobile phone screens are always close to the notch of the positioning groove 32, the staff will adjust the elastic force of the pressure spring 41 according to the specifications or quality of the mobile phone screens. Specifically, the second bolt 8 is screwed in the third avoidance groove 39. The second bolt 8 drives the adjustment plate 7 to move in the positioning groove 32 when it is screwed. The elastic force of the pressure spring 41 is increased during the upward movement of the adjustment plate 7, and the elastic force of the pressure spring 41 is reduced during the downward movement of the adjustment plate 7. In this way, the pressure spring 41 is adjusted. The elastic force adjustment of the spring 41 allows the support plate 4 to be suitable for mobile phone screens of different qualities, further expanding the detection range of mobile phone screens; during the detection process, as the number of mobile phone screens above the support plate 4 decreases, the support plate 4 drives the stacked mobile phone screens to move upward under the elastic force of the pressure-bearing spring 41, and the anti-slip block 322 will be driven to slide in the anti-slip groove 321 during the upward movement of the support plate 4, and the anti-slip block 322 plays an anti-slip effect, so that the support plate 4 will not move out from the upper end of the positioning groove 32 under the action of the pressure-bearing spring 41 with greater elastic force.
