Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone display screen testing, and in particular to a display screen power-on testing device and a testing method. Background Art

[0002] As an advanced display tool, the core function of mobile phone displays is to display electronic files on the screen through specific transmission equipment and reflect them to the human eye. To ensure the quality of each mobile phone display, power-on testing must be carried out during the production process.

[0003] In the traditional testing process, the operator manually connects the connector of the mobile phone display to the docking slot of the tester to ensure a smooth connection between the screen and the test equipment. The operator then draws a square track along the edge of the mobile phone display surface and continuously draws multiple circular tracks within the square to comprehensively test the performance of the display. After the test is completed, the operator manually disconnects the connector from the docking slot, places the tested mobile phone screen in the designated area, and repeats the above steps to test the next screen.

[0004] In the current mobile phone display inspection process, workers need to manually handle a large number of repetitive inspection tasks every day, which not only easily leads to operator fatigue, but also may affect inspection quality and lead to low inspection efficiency. The test quality of products fluctuates, and it is impossible to ensure that every display screen leaving the factory meets high quality requirements. During display inspection, the internal structure of the existing inspection device is only suitable for inspecting a single display screen. It cannot guarantee that the screens of different models are completely fixed in place. The plug-in and unplug interfaces of different display models are also different. The device relies on a guide structure for plug-in and unplug installation. If the display model is different, the interface will be damaged. At the same time, the power supply for the display inspection is not sufficient.

[0005] In current display inspection equipment, the reciprocating cyclic movement of the inspection pen is used to evaluate the color and touch function of the display. However, this reciprocating movement usually relies on multiple cylinders or motors to perform, adding additional electrical components. This not only increases the complexity of the system, but also makes the device easily damaged, affecting inspection efficiency.

[0006] Therefore, a display screen power-on test device and a test method are needed to improve the above problems. Summary of the Invention

[0023] As a preferred solution of the present invention, connecting rods are respectively provided on opposite outer walls of the mounting housing, wherein through-hole grooves are opened on opposite outer walls of the mounting housing, and sliding rods are slidably connected to the inner walls of the through-hole grooves;

[0024] Limiting springs are arranged in an equidistant array on the inner wall of the fixed housing;

[0025] A lower pressing plate is provided on the outer wall of the limit spring, wherein one side of the lower pressing plate is in contact with the outer wall of the display screen for limiting.

[0026] As a preferred solution of the present invention, the controller is connected to the display, the first electro-controlled magnet, the magnetic displacement sensor, the wireless power supply patch, the dual-axis servo motor, the second electro-controlled magnet, the electrical slip ring, the high-definition camera and the drive motor through wires, and the connection method is electrical connection.

[0027] A display screen power-on test method, the specific steps are as follows:

[0028] Operation step 1: Turn on the controller switch to control the drive motor to operate. The drive shaft of the drive motor drives the rotating rod to rotate, and then the rotating rod drives the conveyor belt to rotate through the drive wheel. The conveyor belt drives the magnetic clamp to rotate in a cycle.

[0029] Operation step 2: Install the display screen by inserting the plug-in interface on the inner wall of the charging interface. Then insert the display screen into the inner cavity of the mounting housing through the through-hole slot. Pull the slide bar to move the slide bar along the inner wall of the through-hole slot to fit the model size of the display screen. At the same time, under the elastic pressure of the limit spring, the limit spring drives the lower pressure plate to press down to limit and fix the back of the display screen. Then insert the fixing assembly into the inner cavity of the slide slot.

[0030] Operation step three: When the conveyor belt drives the magnetic clamp to move to one side of the magnetic adsorption block, the magnetic clamp magnetically adsorbs the magnetic adsorption block, and then the magnetic adsorption block drives the fixed components to move. When one set of fixed components moves away, the fixed components located in the inner cavity of the blanking shell slide to the initial position on the inner wall of the chute through the connecting rod, and the blocking rod blocks the fixed components at the same time.

[0031] Operation step 4: When the fixed component is moved by the conveyor belt through the magnetic clamp, since a magnetic induction block is provided on the outer wall of the fixed component, when the magnetic induction block moves to the magnetic displacement sensor, the magnetic displacement sensor generates an electrical signal which is transmitted to the controller through the wire, so that the controller controls the first electro-magnet to be energized to generate magnetism, thereby causing the first electro-magnet to magnetically adsorb the fixed shell. The magnetism of the first electro-magnet is greater than that of the magnetic clamp, thereby causing the first electro-magnet to adsorb and fix the fixed component. Since there are multiple groups of first electro-magnets, multiple groups of fixed components are adsorbed and fixed at the same time. When the first electro-magnet fixes the fixed component, the wireless power supply patch is located directly above the wireless charging patch, and an induced current is generated between the wireless power supply patch and the wireless charging patch, thereby causing the wireless charging patch to power the display screen through the charging interface.

[0032] Operation step five: while the magnetic displacement sensor generates induction to the magnetic induction block, the controller controls the dual-axis servo motor to operate, and the driving shaft of the dual-axis servo motor drives the special-shaped gear to rotate. When the special-shaped gear contacts the tooth groove above the sliding frame, the special-shaped gear applies a thrust to the sliding frame to the right, thereby causing the sliding frame to slide to the right on the inner wall of the limit shell, and the sliding frame drives the flexible connecting rod to move to the right, thereby causing the flexible connecting rod to drive the test pen to slide to the right on the surface of the display screen. Subsequently, when the special-shaped gear contacts the tooth groove below the sliding frame, the special-shaped gear applies a thrust to the sliding frame to the left, thereby causing the sliding frame to slide to the left on the inner wall of the limit shell, and the sliding frame drives the flexible connecting rod to move to the left, thereby causing the flexible connecting rod to drive the test pen to slide to the left on the surface of the display screen, thereby causing the test pen to slide back and forth left and right on the surface of the display screen;

[0033] Operation step six: When the controller controls the second electro-magnet to be energized, the second electro-magnet generates magnetism, thereby causing the second electro-magnet to magnetically attract and connect to the magnetic iron block. When the connecting short rod of the driving shaft of the dual-axis servo motor rotates, the connecting short rod is connected to the magnetic iron block through magnetic coupling to rotate, thereby causing the magnetic iron block to drive the threaded rod to rotate. The threaded rod moves back and forth on the inner wall of the fixed protrusion, applying tension to the dual-axis servo motor. The dual-axis servo motor drives the second slider to move back and forth on the outer wall of the second guide rail through the top plate. The test assembly can drive the test pen to move left and right, front and back. The test pen slides in a square, circular or irregular cycle to test the display screen.

[0034] Operation step seven: When the display screen is tested with a test pen, the high-definition camera captures the screen image of the display screen. The image data captured by the high-definition camera is transmitted through the controller and displayed on the monitor. At the same time, it is observed and judged by the naked eye.

[0035] Operation step eight: After passing the detection, the controller controls the magnetism of the first electro-magnet to weaken, so that the first electro-magnet maintains the fixed component from falling. When the magnetic clamp passes by, the magnetic clamp magnetically adsorbs the magnetic adsorption block, so that the device is transported under the drive of the conveyor belt. When the fixed component moves to one side of the aggregate shell, the aggregate shell blocks the installation shell in the fixed component, and the installation shell falls into the inner cavity of the aggregate shell for collection.

[0036] Compared with the prior art, the present invention can realize the lateral and forward and backward movement of the test pen by arranging a test component in the display screen power-on test equipment, so that the test pen can perform sliding detection in various ways. One end of the dual-axis servo motor drives the special-shaped gear to engage and drive the upper and lower tooth grooves of the sliding frame respectively, so that the sliding frame moves laterally. At the same time, the other end of the dual-axis servo motor magnetically couples the magnetic iron block through the second electric-controlled magnet, so that the magnetic iron block drives the threaded rod to rotate. The threaded rod moves back and forth on the inner wall of the fixed protrusion, applying tension to the dual-axis servo motor, driving the second slider of the top plate to move back and forth on the outer wall of the second guide rail. The structure is simple, and multi-directional movement can be achieved by relying on a single motor, thereby solving the problem that the reciprocating cycle of the detection pen usually relies on multiple cylinders or motors to execute, which adds additional electrical components and system complexity, causing the device to be easily damaged and affecting the detection efficiency.

[0037] The present invention can fix display screens of different models by arranging a fixing component in the display screen power-on test equipment, and the magnetic displacement sensor is sensed through the magnetic induction block, and then the first electro-controlled magnet magnetically adsorbs the fixed shell. Since there are multiple groups of first electro-controlled magnets, multiple groups of fixing components are adsorbed and fixed at the same time. When the first electro-controlled magnet fixes the fixing component, its wireless power supply patch is just located directly above the wireless charging patch. An induced current is generated between the wireless power supply patch and the wireless charging patch to power the display screen, so as to facilitate large-scale testing at the same time, thereby solving the problem that different models of detection screens cannot be guaranteed to be completely fixed in place, and different models of display screens have different plug-in interfaces. The device relies on a guide structure for plug-in installation. If the models of the display screens are different, the interface will be damaged, and the power supply for the detection of the display screen cannot be met.

[0038] The present invention arranges a circulating conveyor belt in the display screen power-on test equipment to adsorb the installed fixed components through a magnetic clamp. When the magnetic displacement sensor generates induction on the magnetic induction block, the first electrically controlled magnet then magnetically adsorbs and fixes the fixed shell, and simultaneously adsorbs multiple groups of fixed components, so that the test component uses a test pen to test the display screen. Multiple groups of display screens are tested simultaneously, thereby solving the problem of worker fatigue affecting the detection quality and resulting in low detection efficiency in the current mobile phone display screen detection process.

Then, the fixing assembly 16 is placed in the inner cavity of the blanking shell 803, and the connecting rod 1602 is inserted into the inner cavity of the slide slot 804.

[0061] While the magnetic displacement sensor 705 generates induction to the magnetic induction block 1612, a second guide rail 710 is installed on the outer wall of the bottom plate 709, a second slider 711 is installed on the outer wall of the second guide rail 710, a top plate 712 is installed on the outer wall of the second slider 711, a dual-axis servo motor 713 is installed on the outer wall of the top plate 712, wherein a limit housing 714 is installed on one side of the dual-axis servo motor 713 and on the base surface of the top plate 712, a sliding frame 715 is slidably connected to the inner wall of the limit housing 714, and the sliding frame 715 is connected to the bottom wall of the bottom plate 712. Tooth grooves 716 are symmetrically arranged on the opposite inner walls, and a special-shaped gear 717 is installed on the driving shaft at one end of the dual-axis servo motor 713, wherein the special-shaped gear 717 is a semicircular arc tooth structure. When the special-shaped gear 717 is engaged with a set of tooth grooves 716, the special-shaped gear 717 and the other set of tooth grooves 716 are disconnected. At the same time, the controller 4 controls the dual-axis servo motor 713 to operate, and the driving shaft of the dual-axis servo motor 713 drives the special-shaped gear 717 to rotate. When the special-shaped gear 717 contacts the tooth groove 716 above the sliding frame 715, the special-shaped gear 717 is engaged with the tooth groove 716 above the sliding frame 715. The special-shaped gear 717 applies a thrust to the sliding frame 715 to the right, thereby causing the sliding frame 715 to slide to the right on the inner wall of the limit shell 714. Flexible connecting rods 724 are installed on the outer wall of the sliding frame 715 from left to right, wherein one end of the flexible connecting rod 724 passes through the mounting groove 6 and extends to the fixed plate 2 where a test pen 725 is installed. One end of the test pen 725 is attached to the surface of the display screen 1606, and the sliding frame 715 drives the flexible connecting rod 724 to move to the right, thereby causing the flexible connecting rod 724 to drive the test pen 7 25 slides to the right on the surface of the display screen 1606. Then, when the special-shaped gear 717 contacts the tooth groove 716 below the sliding frame 715, the special-shaped gear 717 applies a thrust to the sliding frame 715 to the left, thereby causing the sliding frame 715 to slide to the left on the inner wall of the limiting housing 714. The sliding frame 715 drives the flexible connecting rod 724 to move to the left, thereby causing the flexible connecting rod 724 to drive the test pen 725 to slide to the left on the surface of the display screen 1606, thereby causing the test pen 725 to slide back and forth left and right on the surface of the display screen 1606.

[0062] A connecting short rod 718 is installed on the driving shaft at the other end of the dual-axis servo motor 713, a second electro-controlled magnet 719 is installed on the outer wall of the connecting short rod 718, an electrical slip ring 720 is installed on one side of the second electro-controlled magnet 719 and on the outer wall of the connecting short rod 718, a fixing protrusion 721 is installed on the outer wall of the bottom plate 709, one end of the fixing protrusion 721 is threadedly connected to a threaded rod 722, and one end of the threaded rod 722 is installed with a magnetic iron block 723, wherein the magnetic iron block 723 and the second electro-controlled magnet 719 are located in the same horizontal plane, and the connection between the magnetic iron block 723 and the second electro-controlled magnet 719 is a magnetic connection. When the controller 4 controls the second electro-controlled magnet 719 to be energized, the second electro-controlled magnet 719 is energized to generate magnetism, thereby causing the second electro-controlled magnet 719 to be magnetically attracted and connected to the magnetic iron block 723. When the driving shaft of the dual-axis servo motor 713 reaches the connecting short rod 71 When 8 rotates, its connecting short rod 718 is connected to the magnetic iron block 723 through magnetic coupling to rotate, and then the magnetic iron block 723 drives the threaded rod 722 to rotate. Since the threaded rod 722 and the fixed protrusion 721 are connected by a threaded connection, the threaded rod 722 moves back and forth on the inner wall of the fixed protrusion 721, exerting a pulling force on the dual-axis servo motor 713. Its dual-axis servo motor 713 drives the second slider 711 to move back and forth on the outer wall of the second guide rail 710 through the top plate 712. It can be seen from the above that the test component 7 can drive the test pen 725 to move left and right and back and forth. The test pen 725 can slide in a square, circular or irregular cycle to test the display screen 1606, thereby solving the problem that the reciprocating cycle of the test pen usually relies on multiple cylinders or motors to execute, which adds additional electrical components and the complexity of the system, causing the device to be easily damaged, affecting the detection efficiency, and not being energy-saving and environmentally friendly.

[0063] High-definition cameras 726 are symmetrically arranged from left to right at the ports of the positioning housing 702. The high-definition cameras 726 are tilted 45 degrees relative to the ports of the positioning housing 702 and face the fixing assembly 16. When the test pen 725 performs a test on the display screen 1606, the high-definition cameras 726 capture the screen image of the display screen 1606. The image data captured by the high-definition cameras 726 is transmitted by the controller 4 to be displayed on the display 5, and can be observed and judged by the naked eye.

[0064] After passing the detection, the controller 4 controls the magnetism of the first electro-controlled magnet 704 to weaken, so that the first electro-controlled magnet 704 maintains the fixed component 16 from falling. When the magnetic clamp 15 passes by, the magnetic clamp 15 magnetically adsorbs the magnetic adsorption block 1601, so that the device is transported under the drive of the conveyor belt 12. The aggregate shell 802 is installed on the base surface of the mounting base 1, and a discharge plate 810 is installed on the outer wall of the aggregate shell 802. The discharge plate 810 is located between the magnetic clamps 15. Under the action of the limited through groove 811 on the outer wall of the aggregate shell 802, when the fixed component 16 moves to one side of the aggregate shell 802, the aggregate shell 802 blocks the installation shell 1603 in the fixed component 16, and the installation shell 1603 falls into the inner cavity of the aggregate shell 802 for collection.

[0065] The installed fixed component 16 is adsorbed by the circulating conveyor belt 12 through the magnetic clamp 15. When the magnetic displacement sensor 705 generates induction on the magnetic induction block 1612, the first electro-controlled magnet 704 then magnetically adsorbs and fixes the fixed shell 1607, and at the same time adsorbs multiple groups of fixed components 16, so that the test component 7 uses the test pen 725 to test the display screen 1606. Multiple groups of display screens 1606 are tested simultaneously, thereby solving the problem of worker fatigue affecting the inspection quality and resulting in low inspection efficiency in the current mobile phone display inspection process.
