Technical Field

[0001] The present application relates to the field of display screen production technology, and in particular to a modular detection system for 5G mobile phone displays. Background Art

[0002] A smartphone is a general term for mobile phones that, like a personal computer, have an independent operating system and independent running space, on which users can install software, games, navigation and other programs provided by third-party service providers, and can access wireless networks through mobile communication networks. The display screen is one of the core components of a smartphone and its quality needs to be tested after production.

[0003] In the related technology, such as publication number CN113271373A, a modular detection system for a smart phone display screen has the following working principle: by starting the first rodless cylinder, the first rodless cylinder drives the servo motor to move toward one side of the support plate, the servo motor drives the adsorption piece to rotate, and the vertical rodless cylinder drives the vacuum suction cup to move toward the display screen, and the vacuum suction cup sucks the display screen, and then the servo motor rotates to the initial position to place the display screen above the support plate, which makes it easier to absorb the display screen, and through the vertical rodless cylinder, the vacuum suction cup is driven to change its position in the vertical direction to drive the display screen to the required height, and then the vacuum suction cup releases the adsorption of the display screen, which plays a role in testing at different heights; the second rodless cylinder drives the square tube to move in the horizontal direction and supplies air to the cleaning piece, which makes it easier to clean the debris on the top of the support plate.

[0004] With respect to the above-mentioned related technologies, there is a defect that each work process of the device includes loading, drop test and unloading, and one work process realizes the drop detection of one display screen, which leads to low work efficiency in large-scale detection. Summary of the invention

[0005] In order to improve the work efficiency under large-scale detection, the present application provides a modular detection system for 5G mobile phone displays.

[0006] The modular detection system for a 5G mobile phone display provided in this application adopts the following technical solution: A modular detection system for a 5G mobile phone display screen, comprising: frame; A transfer conveyor belt, horizontally arranged on the frame; A striker, arranged on the frame, the striker being located below the transfer conveyor belt; A follower seat connected to the belt of the transfer conveyor belt; Fixture seat, for clamping and fixing the workpiece; A lifting drive assembly is connected to the jig seat, and is used to enable the jig seat to have a transfer state, a falling state, and a lifting state. In the transfer state, the distance between the jig seat and the follower seat is constant. In the falling state, the jig seat descends due to its own gravity. In the lifting state, the jig seat gradually rises.

[0007] By adopting the above technical solution, the workpiece is first fixed on the jig seat, and then the follower seat is gradually moved forward by the transfer conveyor belt. When it moves above the striker, the jig seat is then placed in a falling state through the lifting drive assembly to achieve a drop test. Finally, the jig seat is placed in a lifted state through the lifting drive assembly until the jig seat is in a transfer state. With this design, the workpiece can be loaded and unloaded in the transfer state, while other jig seats can be in a dropped state or a lifted state, so there is overlap between the test cycles of each workpiece. In addition, the workpiece can be loaded and unloaded in the transfer state far away from the lifted state and the dropped state, so it can be adapted to batch loading robots, thereby improving work efficiency under large-scale inspections.

[0008] Preferably, the following seat is detachably arranged on the belt of the transfer conveyor belt.

[0009] By adopting the above technical solution, the distance between two adjacent follower seats can be changed accordingly according to the size specifications of the workpiece, thereby improving the adaptability of the detection system.

[0010] Preferably, the following seat is provided with a hand pump suction cup, and the following seat is connected to the belt of the transfer conveyor belt through the hand pump suction cup.

[0011] By adopting the above technical solution, compared with the method of fixing by bolts, this design method, first, does not need to destroy the structure of the transfer conveyor belt to improve the transfer stability of the transfer conveyor belt; second, it is convenient for the staff to operate the fixing work of the follower seat.

[0012] Preferably, the lifting drive assembly includes a self-contracting variable-pitch connection, a following track and a following slide, the self-contracting variable-pitch connection connects the following seat and the fixture seat in series, the self-contracting variable-pitch connection makes the force of the following seat and the fixture seat closing together smaller than the gravity of the fixture seat, and the closing force is parallel to the direction of the connection between the following seat and the fixture seat; the following track is arranged on the frame, the following track is provided with a slide hole, the slide hole is arranged around the transfer conveyor belt, the slide hole is divided into a transfer section, a dropping section and a lifting section, the distance between different positions of the transfer section and the belt of the transfer conveyor belt is constant, the dropping section is located below the transfer belt, the dropping section is vertically extended, the lifting section is located below the transfer belt, and the lifting section is inclined upward; one end of the following slide is connected to the fixture seat, and the other end is slidably passed through the slide hole.

[0013] By adopting the above technical solution, the follower seat will allow the fixture seat to move along the follow-up track through the self-contracting variable-pitch connector. At the same time, the closing force exerted by the self-contracting variable-pitch connector is less than the gravity of the fixture seat. When the fixture seat moves to the dropping section, the fixture seat will be in a dropping state, and the drop test will be realized. When the fixture seat moves to the lifting section, the fixture seat will be in a lifting state. Subsequently, when the fixture seat moves to the transfer section, the fixture seat will be in a transfer state. In this design method, first, the lifting drive assembly has no components with a driving source, so there is no need to consider how the power of the driving source is transmitted during the movement of the follower seat, thereby making the structure of the detection system simpler; second, due to the closing force exerted by the self-contracting variable-pitch connector, the follower seat can still keep moving forward during the falling process of the fixture seat, so the transfer conveyor belt does not need to stop to complete the drop test, thereby improving the work efficiency under large-scale detection.

[0014] Preferably, the self-retracting variable-pitch connecting member includes a rope winding shaft, a connecting rope and a winding torsion spring. The rope winding shaft is rotatably connected to the follower seat, one end of the connecting rope is wound and fixed on the rope winding shaft, and the other end is connected to the fixture seat. The winding torsion spring is connected to the rope winding shaft and is used to apply a torque to the rope winding shaft to reel in the connecting rope.

[0015] By adopting the above technical solution, compared with the self-contracting variable-pitch connector that adopts a self-contracting multi-section telescopic rod, this design method can make the connecting rope send out more smoothly when the fixture seat is in a dropped state, and can make the connecting rope reel in more smoothly when the fixture seat is in a raised state, thereby further improving the transmission speed of the conveyor belt and improving the work efficiency under large-scale inspection.

[0016] Preferably, the inclination angle of the lifting section is less than 20°.

[0017] By adopting the above technical solution, the gravity component of the jig seat along the lifting section can be weakened, so that the jig seat can move more smoothly in the lifting section, thereby reducing the distance difference between the jig seat and the follower seat in the transmission direction of the transmission conveyor belt when in the lifting state, thereby avoiding interference between two adjacent workpieces.

[0018] Preferably, the frame is provided with a lifting and blowing member, and the lifting and blowing member is located below the lifting section and is used to apply an upward lifting force to the fixture seat.

[0019] By adopting the above technical solution, the jig seat can move more smoothly in the lifting section, so as to improve the movement synchronization of the jig seat and the follower seat in the transmission direction of the transmission conveyor belt, thereby reducing the time for the transmission conveyor belt to slow down and adjust, thereby improving work efficiency.

[0020] Preferably, between one of the jig seats and one of the follower seats, a plurality of the self-contracting variable-distance connecting members are provided, and the plurality of the self-contracting variable-distance connecting members are distributed along the movement direction of the follower seat.

[0021] By adopting the above technical solution, the lifting drive assembly can exert a more uniform pulling force on the fixture seat, so that when the fixture seat is in a falling state, the lower surface of the workpiece can be smoother, thereby completing the drop test more accurately.

[0022] Preferably, the fixture seat includes a seat body, a clamping block and a self-retracting clamping spring, the seat body is connected to the lifting drive assembly, the clamping block is slidably connected to the seat body, four clamping block parts are provided, the four clamping block parts move toward or away from the center of the seat body, and an opening guide surface is provided on the side of the clamping block part away from one end of the seat body and close to the center of the seat body, the opening guide surface is used to abut against the workpiece, and the self-retracting clamping spring is connected to the clamping block part, and is used to apply a closing force to the four clamping block parts.

[0023] By adopting the above technical solution, the distances between the four clamping block parts and the center of the seat body part can be changed, so workpieces of different sizes and specifications can be adapted.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. First fix the workpiece on the fixture seat, then let the follower seat gradually move forward through the conveyor belt, and when it moves to the top of the striker, the fixture seat is placed in a falling state through the lifting drive assembly to achieve a drop test, and finally the fixture seat is placed in a lifting state through the lifting drive assembly until the fixture seat is placed in a transfer state. With this design, the workpiece can be loaded and unloaded in the transfer state, while other fixture seats can be in a falling state or a lifting state, so there is an overlap between the test cycles of each workpiece. In addition, the workpiece can be loaded and unloaded in the transfer state far away from the lifting state and the falling state, so it can be adapted to the batch loading robot, thereby improving the work efficiency under large-scale inspection; 2. The follower seat will allow the fixture seat to move along the follow track through the self-contracting variable-pitch connector. At the same time, the closing force applied by the self-contracting variable-pitch connector is less than the gravity of the fixture seat. When the fixture seat moves to the dropping section, the fixture seat will be in a dropping state to achieve the drop test. When the fixture seat moves to the lifting section, the fixture seat will be in a lifting state. Subsequently, when the fixture seat moves to the transfer section, the fixture seat will be in a transfer state.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] An embodiment of the present application discloses a modular detection system for a 5G mobile phone display.

[0030] Reference Figure 1 and Figure 2 The modular detection system of 5G mobile phone display screen includes a frame 1, a transfer conveyor belt 2, a striker 3, a follower seat 4 and a fixture seat 5. The transfer conveyor belt 2 is horizontally arranged on the frame 1, and the horizontal direction here refers to the length direction of the transfer conveyor belt 2, which is horizontally extended; the striker 3 is installed on the frame 1, and the striker 3 is located below the transfer conveyor belt 2; the follower seat 4 is connected to the belt of the transfer conveyor belt 2, and there are multiple follower seats 4 distributed around the conveying direction of the transfer conveyor belt 2; the fixture seat 5 is used for clamping and fixing the workpiece, and one fixture seat 5 corresponds to one follower seat 4; the lifting drive component 6 is connected to the fixture seat 5, which will make the fixture seat 5 have a transfer state, a falling state and a lifting state, wherein in the transfer state, the distance between the fixture seat 5 and the follower seat 4 is constant, in the falling state, the fixture seat 5 descends with its own gravity, and in the lifting state, the fixture seat 5 gradually rises.

[0031] Reference Figure 1 and Figure 2 The working principle of the drop test is as follows: first, fix the workpiece on the jig seat 5, then let the follower seat 4 gradually move forward through the transfer conveyor belt 2, and when it moves to above the striker 3, the jig seat 5 is then placed in a falling state through the lifting drive assembly 6 to achieve the drop test, and finally, the jig seat 5 is placed in a lifting state through the lifting drive assembly 6 until the jig seat 5 is placed in a transfer state. It can be seen from the working process that the workpiece can be loaded and unloaded in the transfer state, while other jig seats 5 can be in a dropping state or a lifting state, so there is overlap between the test cycles of each workpiece, and the workpiece can be loaded and unloaded in the transfer state far away from the lifting state and the dropping state, so it can be adapted to a batch loading robot, thereby improving the work efficiency under large-scale inspection.

[0032] In addition, considering that the following seat 4 needs to pass through the corner of the transfer conveyor belt 2, the corner of the transfer conveyor belt 2 will have a plurality of belt rollers distributed in a circumferential manner.

[0033] Reference Figure 1 and Figure 2 In order to adapt to workpieces of different sizes, the following settings are correspondingly arranged. First, the follower seat 4 is detachably arranged on the belt of the transfer conveyor belt 2 so as to change the distance between two adjacent follower seats 4. Specifically, the follower seat 4 is provided with a hand pump suction cup, and the follower seat 4 is connected to the belt of the transfer conveyor belt 2 through the hand pump suction cup, so that it will not damage the structure of the transfer conveyor belt 2, and it is also convenient for the staff to operate the fixing work of the follower seat 4.

[0034] Reference Figure 1 and Figure 2 Secondly, each fixture seat 5 includes a seat body 51, a clamping block 52 and a self-closing clamping spring 53. The seat body 51 is roughly in the shape of a rectangular parallelepiped. The seat body 51 is connected to the lifting drive assembly 6. The clamping block 52 is slidably connected to the seat body 51. Four clamping block parts 52 are provided. The four clamping block parts 52 move toward or away from the center of the seat body 51. The clamping block part 52 is away from one end of the seat body 51 and is close to the center of the seat body 51. An opening guide surface 521 extending obliquely is formed on the side. The opening guide surface 521 will abut against the workpiece to allow the four clamping block parts 52 to open when the workpiece moves toward the seat body 51. The self-closing clamping spring 53 is connected to the clamping block part 52, which will apply a closing force to the four clamping block parts 52, so that workpieces of different sizes can be clamped.

[0035] Reference Figure 1 and Figure 2 In order to realize the falling and rising of the fixture seat 5 through a simpler structure, and to complete the drop test without stopping the conveyor belt 2, the following settings are correspondingly arranged. The lifting drive assembly 6 includes a self-contracting variable-pitch connection 61, a following track 62 and a following slide 63. The self-contracting variable-pitch connection 61 connects the following seat 4 and the fixture seat 5 in series. The self-contracting variable-pitch connection 61 makes the force of closing the following seat 4 and the fixture seat 5 smaller than the gravity of the fixture seat 5. This closing force is parallel to the connection direction between the following seat 4 and the fixture seat 5; the following track 62 is arranged On the frame 1, a slide hole 7 is opened on the follower rail 62, and the slide hole 7 is arranged around the transfer conveyor belt 2. The slide hole 7 is divided into a transfer section 71, a drop section 72 and a lifting section 73. The distance between different positions of the transfer section 71 and the belt of the transfer conveyor belt 2 is constant. The drop section 72 is located below the transfer belt, and the drop section 72 is vertically extended. The lifting section 73 is located below the transfer belt, and the lifting section 73 is inclined upward; one end of the follower slide 63 is connected to the seat body 51 of the jig seat 5, and the other end is slidably passed through the slide hole 7.

[0036] Reference Figure 1 and Figure 2 When the transfer conveyor belt 2 is working, the following seat 4 will allow the fixture seat 5 to move along the following track 62 through the self-contracting variable-distance connecting piece 61. At the same time, the closing force applied by the self-contracting variable-distance connecting piece 61 is less than the gravity of the fixture seat 5. When the fixture seat 5 moves to the dropping section 72, the fixture seat 5 will be in a dropping state, and the drop test will be realized. When the fixture seat 5 moves to the lifting section 73, the fixture seat 5 will be in a lifting state. Subsequently, the fixture seat 5 moves to the transfer section 71, and the fixture seat 5 will be in a transfer state, thereby achieving the purpose of realizing large-scale detection without stopping the machine, and this structure that realizes lifting and lowering through the track is also relatively simple.

[0037] Reference Figure 1 and Figure 2In order to realize the lifting and lowering of the fixture seat 5 more smoothly through the track structure, the self-retracting variable-pitch connecting member 61 includes a rope winding shaft 611, a connecting rope 612 and a winding torsion spring 613. The rope winding shaft 611 is rotatably connected to the follower seat 4. One end of the connecting rope 612 is wound and fixed on the rope winding shaft 611, and the other end is connected to the seat body 51 of the fixture seat 5. The winding torsion spring 613 is connected to the rope winding shaft 611, which will apply a torque to the rope winding shaft 611 to reel in the connecting rope 612. The resistance to the falling and rising process of the fixture seat 5 is only the contact friction between the connecting rope 612 and the rope winding shaft 611, so the movement of the fixture seat 5 can be smoother, thereby further improving the transmission speed of the transmission conveyor belt 2 and improving the work efficiency under large-scale inspection.

[0038] In other embodiments, if the accuracy of the components is met, the self-contracting variable-distance connecting member 61 may adopt a self-contracting multi-section telescopic rod structure.

[0039] Reference Figure 1 and Figure 2 In order to improve the smoothness of the movement of the jig seat 5 in the lifting section 73, the following settings are correspondingly made. First, the inclination angle of the lifting section 73 is less than 20°, which can weaken the gravity component of the jig seat 5 along the direction of the lifting section 73, so that the jig seat 5 can move more smoothly in the lifting section 73, so as to weaken the distance difference between the jig seat 5 and the follower seat 4 in the transmission direction of the transmission conveyor belt 2 in the lifting state, thereby avoiding interference between two adjacent workpieces; second, the frame 1 is provided with a lifting blowing member 8, which is located below the lifting section 73 and will apply an upward lift to the jig seat 5, thereby further allowing the jig seat 5 to move more smoothly in the lifting section 73, so as to improve the movement synchronization of the jig seat 5 and the follower seat 4 in the transmission direction of the transmission conveyor belt 2, thereby reducing the time for the transmission conveyor belt 2 to slow down and adjust, thereby improving work efficiency.

[0040] Reference Figure 1 and Figure 2 In order to make the lower surface of the workpiece smoother to complete the drop test, a plurality of self-contracting variable-distance connecting members 61 are arranged between a fixture seat 5 and a follower seat 4, and the plurality of self-contracting variable-distance connecting members 61 are distributed along the movement direction of the follower seat 4.

[0041] The implementation principle of a modular detection system for a 5G mobile phone display screen in an embodiment of the present application is as follows: first fix the workpiece on the jig seat 5, then let the follower seat 4 gradually move forward through the transfer conveyor belt 2, and when it moves to above the striker 3, then let the jig seat 5 be in a falling state through the lifting drive assembly 6 to achieve a drop test, and finally let the jig seat 5 be in a lifting state through the lifting drive assembly 6 until the jig seat 5 is in a transfer state. With this design, the workpiece can be loaded and unloaded in the transfer state, while other jig seats 5 can be in a falling state or a lifting state, so there is an overlap between the test cycles of each workpiece. In addition, the workpiece can be loaded and unloaded in the transfer state far away from the lifting state and the falling state, so it can be adapted to a batch loading robot, thereby improving the work efficiency under large-scale detection.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
