Description

Technical Field

[0002] As an advanced display tool, the core function of mobile phone display is to display electronic files on the screen through specific transmission equipment and reflect them to human eyes. In order to ensure the quality of each mobile phone display, power-on test 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 smooth connection between the screen and the test equipment. Then, the operator draws a square track along the edge of the surface of the mobile phone display and continuously draws multiple circular tracks inside the square to comprehensively test the performance of the display. After the test is completed, the operator needs to manually disconnect the connector and the docking slot, place the tested mobile phone screen in the designated area, and then repeat the above steps to test the next screen;

[0004] In the current mobile phone display screen 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 the inspection quality and lead to low inspection efficiency. In addition, the product test quality fluctuates, and it is impossible to ensure that every display screen shipped out of the factory meets high quality requirements. When inspecting the display screen, the internal structure of the existing inspection device can only be suitable for a single display screen inspection. For different models of inspection screens, it cannot be guaranteed to be completely fixed in place. The plug-in interfaces of different models of display screens are also different. The device relies on a guide structure for plug-in and installation. If the display screen models are different, the interface will be damaged. At the same time, the power supply for the display screen inspection cannot be met.

[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 execute, adding additional electrical components. This not only increases the complexity of the system, but also makes the device easily damaged, affecting the 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

[0018] As a preferred solution of the present invention, a magnetic induction block is installed on one side of the wireless charging patch and on the outer wall of the connecting shell, a charging interface is installed on the inner wall of the connecting shell, one end of the charging interface is connected to the wireless charging patch, and the other end of the charging interface is connected to the plug-in port of the display screen for electrical connection, and the controller is respectively 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.

[0019] A display screen power-on test method, the specific steps are as follows:

[0020] Operation step 1: Turn on the switch of the controller so that the controller controls the driving motor to operate, and the driving shaft of the driving motor drives the rotating rod to rotate, and then the rotating rod drives the conveyor belt to rotate through the driving wheel, and the conveyor belt drives the magnetic clamp to rotate in a cycle;

[0021] Operation step 2: Install the display screen by inserting the plug-in interface of the display screen on the inner wall of the charging interface, then insert the display screen into the inner cavity of the installation shell through the through-hole slot, pull the slide bar to move the slide bar on the inner wall of the through-hole slot to fit the model size of the display screen, and at the same time, under the elastic extrusion 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, and then insert the fixing component into the inner cavity of the slide slot;

[0022] 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 component to move. When a group of fixed components are moved away, the fixed components located in the inner cavity of the unloading shell slide to the initial position on the inner wall of the slide slot through the connecting rod, and the blocking rod blocks and limits the fixed components at the same time;

[0023] Operation step 4: When the fixed component is moved by the conveyor belt through the magnetic clamp, since a magnetic induction block is arranged 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-controlled magnet to be energized to generate magnetism, thereby causing the first electro-controlled magnet to magnetically adsorb the fixed shell, and the magnetism of the first electro-controlled magnet is greater than that of the magnetic clamp, thereby causing the first electro-controlled magnet to adsorb and fix the fixed component. Since there are multiple groups of the first electro-controlled magnets, multiple groups of fixed components are adsorbed and fixed at the same time. When the first electro-controlled magnet fixes the fixed component, its wireless power supply patch is located just 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;

[0024] 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. When the driving shaft of the dual-axis servo motor drives the special-shaped gear to contact the tooth groove above the sliding frame, the special-shaped gear applies a thrust to the sliding frame to the right, so that the sliding frame slides 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, so that the flexible connecting rod drives the test pen to slide to the right on the surface of the display screen. Then, 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, so that the sliding frame slides 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, so that the flexible connecting rod drives the test pen to slide to the left on the surface of the display screen, so that the test pen slides back and forth left and right on the surface of the display screen;

[0025] Operation step six: When the controller controls the second electro-controlled magnet to be energized, the second electro-controlled magnet is energized to generate magnetism, thereby causing the second electro-controlled magnet to magnetically adsorb 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, exerting a pulling force on 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. From the above, it can be seen that the test component can drive the test pen to move left and right, front and back, and the test pen can slide in a square, circular or irregular cycle to test the display screen;

[0026] Operation step seven: When the display screen is tested by the test pen, its high-definition camera takes pictures of the screen. The image data taken by the high-definition camera is transmitted through the controller and displayed on the display. At the same time, it is observed and judged by the naked eye.

[0027] 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 and does not fall. When the magnetic clamp passes by, the magnetic clamp magnetically adsorbs the magnetic adsorption block so that the device is transported by 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.

[0028] 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 respectively engage and drive the upper and lower tooth grooves of the sliding frame, 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, and a pulling force is applied to the dual-axis servo motor to drive 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 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.

[0029] The present invention can realize that the device 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 the first electro-controlled magnet is provided with multiple groups, 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, and 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 detection 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 and installation. If the models of the display screens are different, the interface will be damaged, and the detection power supply for the display screen cannot be satisfied.

[0030] The present invention arranges a cyclically rotating 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 adsorbs multiple groups of fixed components at the same time, so that the test component uses a test pen to test the display screen, and multiple groups of display screens are tested simultaneously, thereby solving the problem of worker fatigue affecting the detection quality and causing low detection efficiency in the current mobile phone display screen detection process.

A display screen power-on test method, implemented according to the display screen power-on test device according to claim 9, wherein the steps are as follows: Operation step 1: by turning on the switch of the controller (4), the controller (4) controls the driving motor (10) to operate, and the driving shaft of the driving motor (10) drives the rotating rod (9) to rotate, and then the rotating rod (9) drives the conveyor belt (12) to rotate through the driving wheel (11), and the conveyor belt (12) drives the magnetic clamp (15) to rotate in a circular manner; Operation step 2: Install the display screen (1606) by inserting the plug-in interface of the display screen (1606) on the inner wall of the charging interface (1613), then insert the display screen (1606) into the inner cavity of the installation shell (1603) through the through hole groove (1604), pull the slide bar (1605) to move the slide bar (1605) on the inner wall of the through hole groove (1604) to fit the model size of the display screen (1606), and at the same time, under the elastic extrusion of the limit spring (1608), the limit spring (1608) drives the lower pressure plate (1609) to press down to limit and fix the back of the display screen (1606), and then place the fixing component (16) in the inner cavity of the blanking shell (803), and insert the connecting rod (1602) into the inner cavity of the slide groove (804); Operation step three: When the conveyor belt (12) drives the magnetic clamp (15) to move to one side of the magnetic adsorption block (1601), the magnetic clamp (15) magnetically adsorbs the magnetic adsorption block (1601), thereby causing the magnetic adsorption block (1601) to drive the fixed component (16) to move. When one group of fixed components (16) is moved away, the fixed components (16) located in the inner cavity of the unloading shell (803) slide on the inner wall of the slide groove (804) in sequence to the initial position through the connecting rod (1602), and at the same time, the blocking rod (808) blocks and limits the fixed components (16); Operation step 4: When the fixed component (16) is moved by the conveyor belt (12) through the magnetic clamp (15), since the magnetic induction block (1612) is arranged on the outer wall of the fixed component (16), when the magnetic induction block (1612) moves to the magnetic displacement sensor (705), the magnetic displacement sensor (705) generates an electrical signal which is transmitted to the controller (4) through the wire, so that the controller (4) controls the first electro-controlled magnet (704) to be energized to generate magnetism, thereby causing the first electro-controlled magnet (704) to magnetically adsorb the fixed housing (1607), and the magnetism of the first electro-controlled magnet (704) is greater than that of the magnetic clamp. (15), thereby causing the first electro-controlled magnet (704) to adsorb and fix the fixed component (16). Since the first electro-controlled magnet (704) is provided with multiple groups, multiple groups of fixed components (16) are adsorbed and fixed at the same time. When the first electro-controlled magnet (704) fixes the fixed component (16), its wireless power supply patch (706) is located just above the wireless charging patch (1611), and an induced current is generated between the wireless power supply patch (706) and the wireless charging patch (1611), thereby causing the wireless charging patch (1611) to power the display screen (1606) through the charging interface (1613); Operation step 5: While the magnetic displacement sensor (705) generates induction to the magnetic induction block (1612), 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) 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 housing (714), and the sliding frame (715) drives the flexible connecting rod (724) to move to the right, thereby causing the flexible connecting rod (724) to move to the right. 724) drives the test pen (725) to slide to the right on the surface of the display screen (1606), and 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 limit housing (714), and 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); Operation step six: 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 adsorbed and connected to the magnetic iron block (723). When the connecting short rod (718) connected to the driving shaft of the dual-axis servo motor (713) rotates, the connecting short rod (718) is connected to the magnetic iron block (723) through magnetic coupling and rotates, thereby causing the magnetic iron block (723) to drive the threaded rod (722) to rotate. The threaded rod (722) moves forward and backward on the inner wall of the fixed protrusion (721), exerting a pulling force on the dual-axis servo motor (713), and the dual-axis servo motor (713) drives the second slider (711) to move forward and backward on the outer wall of the second guide rail (710) through the top plate (712). As can be seen from the above, the test component (7) can drive the test pen (725) to move left and right and forward and backward, and the test pen (725) performs square, circular or irregular circular sliding to test the display screen (1606); Operation step seven: when the display screen (1606) is tested by the test pen (725), the high-definition camera (726) takes a picture of the screen of the display screen (1606), and the image data taken by the high-definition camera (726) is transmitted through the controller (4) and displayed on the display (5), and at the same time, the test is observed and judged by the naked eye; Operation step eight: 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). 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.
