[0041] As Figure 1 illustrated, some embodiments of the disclosure provide a display device 1000, which can be any device displaying anything whether moving (e.g., video) or stationary (e.g., still image) and whether text or image.
[0042] Exemplarily, the display device 1000 can be any product or component having a display function, such as a television, a notebook computer, a tablet computer, a mobile phone, a personal digital assistant (PDA), a navigator, a wearable device, an augmented reality (AR) device, a virtual reality (VR) device, an in-vehicle display, a flight display, etc.
[0043] In some examples, the display device 1000 can be a large display product. For example, the display device 1000 can be a television.
[0044] In yet other examples, the display device 1000 can be a wearable device. For example, the display device 1000 can be a watch.
[0045] In some embodiments, as Figure 2 illustrated, the display device 1000 includes a display panel 100 and a printed circuit board 200 (PCB).
[0046] The type of the display panel 100 described above includes a variety, which can be selected and arranged according to actual needs.
[0047] Exemplarily, the display panel 100 can be an organic light-emitting diode (OLED) display panel 100, a quantum dot light-emitting diode (QLED) display panel 100, an active matrix organic light-emitting diode (AMOLED) display panel 100, a liquid crystal display (LCD) display panel 100, or a mini / micro light-emitting display (MLED) display panel 100, and the like, which are not specifically limited in the embodiments of the present disclosure.
[0048] The printed circuit board 200 is used to connect the display panel 100 and an external host, the external host is used to deliver signals to the display panel 100, and the printed circuit board 200 is used to control and process the delivered signals to make the display panel 100 display images.
[0049] It can be understood that the external host is a device that provides a signal source for the display panel 100, which is various in type and different in function, but outputs specific signals to the display panel 100, and the signals are processed and controlled by the printed circuit board 200, and finally various images, texts and audio contents are presented on the display panel 100.
[0050] In some examples, the external host includes a personal computer, a notebook computer, a video playing device and a game host.
[0051] In the process of manufacturing the display device 1000, the pins of the printed circuit board 200 need to be detected to determine whether the pins of the printed circuit board 200 are damaged, and if the pins of the printed circuit board 200 are damaged, the display panel 100 cannot be lighted.
[0052] In the related art, whether the pins of the printed circuit board are damaged is determined by an artificial detection method. However, the artificial detection method has a low result accuracy. The inventors have found that the printed circuit board can be seen by the detection personnel after the display panel and the printed circuit board are inclined, and therefore, the detection personnel needs to keep the display panel and the printed circuit board inclined at a fixed angle during the detection. However, under the influence of various factors (for example, fatigue), the angle at which the display panel and the printed circuit board are inclined is not fixed, thereby causing some printed circuit boards not to be detected by the detection personnel, and thus causing the detection result of the detection personnel to be wrong, that is, the result accuracy of the artificial detection method is low.
[0053] To solve the above technical problems, some embodiments of the present disclosure provide a detection device 2000 as shown in Figure 3 and Figure 4 The detection device 2000 includes a fixed plate 10, a support plate 20, and an adjusting rod 30. The fixed plate 10 is configured to be connected to a rack.
[0054] The support plate 20 is located on one side of the fixed plate 10, and the support plate 20 is configured to rotate relative to the fixed plate 10 about a first axis X1 as shown in Figure 3 , Figure 4 and Figure 5 The first axis X1 extends in a first direction M1 and is parallel to the fixed plate 10. The support plate 20 is configured to support a display panel 100 and a printed circuit board connected to the display panel 100.
[0055] The adjusting rod 30 intersects the fixed plate 10 and is connected to the support plate 20. The adjusting rod 30 is configured to move relative to the fixed plate 10 along the extension direction of the adjusting rod 30 and drive the support plate 20 to rotate relative to the fixed plate 10 about the first axis X1. Exemplarily, the adjusting rod 30 is perpendicular to the fixed plate 10.
[0056] With this arrangement, as shown in Figure 6 , the adjusting rod 30 moves towards the support plate 20, which can drive the support plate 20 to rotate relative to the fixed plate 10 about the first axis X1 away from the fixed plate 10, thereby tilting the support plate 20. During the detection process, keeping the position of the adjusting rod 30 unchanged can keep the angle of the support plate 20 unchanged. In this way, the pins of the printed circuit board can be fully detected by the detection personnel, which can reduce the risk of detection errors by the detection personnel and improve the accuracy of the detection results.
[0057] In some embodiments, as shown in Figure 5 , the detection device 2000 further includes a first support seat 40, a second support seat 50, and a support shaft 101.
[0058] The first support seat 40 includes a first support portion 41 and a second support portion 42. The first support portion 41 extends in a first direction, and the second support portion 42 extends in a direction perpendicular to the support plate 20. One end of the first support portion 41 and one end of the second support portion 42 are fixedly connected. The first support portion 41 is fixedly connected to the fixed plate 10. The second support portion 42 has a sixth hole 421, and the axis of the sixth hole 421 is parallel to the first direction M1.
[0059] The second support base 50 extends in a direction perpendicular to the support plate 20 and is fixedly connected to the support plate 20 at one end. The second support base 50 has a seventh hole 51, and the axis of the seventh hole 51 is parallel to the first direction M1. Exemplarily, the second support base 50 is fixedly connected to the support plate 20 by a first fastener 1, for example, the first fastener 1 includes a screw.
[0060] The support shaft 101 extends in the first direction M1. One end of the support shaft 101 is embedded in the sixth hole 421 and can rotate relative to the second support portion 42 about the axis of the sixth hole 421. The other end of the support shaft 101 is embedded in the seventh hole 51 and is fixedly connected to the second support base 50. In this way, the support plate 20 can be rotated relative to the fixed plate 10 about the first axis X1.
[0061] In some embodiments, as shown in Figure 4 、 Figure 6 and Figure 7 , the fixed plate 10 has a first through hole extending through the fixed plate 10, and the adjustment rod 30 is arranged in the first through hole. The detection device 2000 further includes a first adjustment block 60. The first adjustment block 60 is located on the side of the fixed plate 10 away from the support plate 20 and is fixedly connected to the fixed plate 10. The first adjustment block 60 is provided with a first threaded hole 61, and the adjustment rod 30 is screwed with the first threaded hole 61.
[0062] In this way, rotating the adjustment rod 30 can move the adjustment rod 30 towards the support plate 20, thereby driving the support plate 20 to rotate relative to the fixed plate 10 about the first axis X1 away from the fixed plate 10.
[0063] In some examples, the first adjustment block 60 and the fixed plate 10 are fixedly connected by a screw.
[0064] In other examples, the first adjustment block 60 and the fixed plate 10 are fixedly connected by a rack.
[0065] In some embodiments, as shown in Figure 4 、 Figure 6 and Figure 7 , the detection device 2000 further includes a knob 70. The knob 70 is located on the side of the first adjustment block 60 away from the fixed plate 10 and is fixedly connected to the end of the adjustment rod 30 away from the support plate 20.
[0066] In this way, rotating the knob 70 can rotate the adjustment rod 30, thereby driving the support plate 20 to rotate relative to the fixed plate 10 about the first axis X1 away from the fixed plate 10.
[0067] In other embodiments, the detection device 2000 further includes a first motor and a retractable coupling. The first motor is located on the side of the fixed plate 10 away from the support plate 20, and the housing of the first motor is fixedly connected to the first adjustment block 60. One end of the retractable coupling is connected to the rotating shaft of the first motor, and the other end is connected to the end of the adjustment rod 30 away from the support plate 20.
[0068] In this manner, the rotation of the first electrode can cause the adjustment rod 30 to rotate, thereby driving the support plate 20 to rotate relative to the fixing plate 10 around the first axis X1 in a direction away from the fixing plate 10 .
[0069] It should be noted that a telescopic coupling refers to a coupling that can be extended and retracted to a certain length in the axial direction.
[0070] Exemplarily, the telescopic coupling includes a sliding telescopic coupling, a gear telescopic coupling, and a bellows telescopic coupling.
[0071] In some embodiments, as Figure 7 As shown, the detection device 2000 further includes a second adjustment block 80 , an adjustment wheel 90 and an adjustment shaft 110 .
[0072] Among them, such as Figure 7 As shown, the second adjustment block 80 is located between the support plate 20 and the fixed plate 10, and is fixedly connected to the support plate 20. Along the first direction M1, a first groove 81 is provided on the surface of the second adjustment block 80, and the first groove 81 extends along the second direction M2. The second direction M2 is perpendicular to the first direction M1 and parallel to the fixed plate 10.
[0073] The adjusting wheel 90 is located in the first groove 81. The adjusting wheel 90 can move along the first groove 81 relative to the second adjusting block 80, and can rotate along the axis of the adjusting wheel 90 relative to the second adjusting block 80. The axis of the adjusting wheel 90 is parallel to the first direction M1. The adjusting wheel 90 has a second through hole 91, and the axis of the second through hole 91 coincides with the axis of the adjusting wheel 90.
[0074] The adjusting shaft 110 is passed through the second through hole 91 and fixedly connected to the adjusting wheel 90. The adjusting shaft 110 has a third through hole 1101. The adjusting rod 30 is also passed through the third through hole 1101 and fixedly connected to the adjusting shaft 110. Exemplarily, the adjusting rod 30 and the adjusting shaft 110 are fixedly connected by a set screw.
[0075] In this way, the adjusting rod 30 and the support plate 20 are connected through the second adjusting block 80, the adjusting wheel 90 and the adjusting shaft 110. When the adjusting rod 30 moves towards the support plate 20, the adjusting shaft 110 and the adjusting wheel 90 can be driven to move along the first groove 81 away from the first axis X1, so that the second adjusting block 80 and the support plate 20 rotate relative to the fixed plate 10 around the first axis X1 away from the fixed plate 10, thereby tilting the support plate 20 and improving the accuracy of the detection result.
[0076] In some examples, as shown in Figure 7 , the detection device 2000 includes two second adjusting blocks 80, two adjusting wheels 90 and one adjusting shaft 110. The first grooves 81 in the two second adjusting blocks 80 are oppositely arranged. One adjusting wheel 90 is located in one first groove 81, and one end of the adjusting shaft 110 is arranged in one third through hole 1101 and the other end is arranged in another third through hole 1101.
[0077] In some examples, the detection device 2000 further includes a third adjusting block 120, which is located between the two second adjusting blocks 80 and the support plate 20 and is fixedly connected with the two second adjusting blocks 80 and the support plate 20. In this way, the third adjusting block 120 forms a whole with the two second adjusting blocks 80, thereby facilitating disassembly and installation.
[0078] In some embodiments, as shown in Figure 4 , Figure 6 and Figure 8 , the support plate 20 and the fixed plate 10 have a gap therebetween, so that the included angle between the support plate 20 and the fixed plate 10 is -90°-90°. In this way, the range of the angle of the support plate 20 can be enlarged, which is beneficial to expand the use range of the detection device 2000.
[0079] Exemplarily, the included angle between the support plate 20 and the fixed plate 10 is -89°, -60°, -45°, -30°, -10°, 0°, 20°, 30°, 50°, 70° and 89°.
[0080] In some embodiments, as shown in Figure 9 , the detection device 2000 further includes an angle gauge 130, which is located on the side of the fixed plate 10 close to the support plate 20, on the side of the support plate 20 along the first direction M1, and is connected with the fixed plate 10. The angle gauge 130 is perpendicular to the first axis X1.
[0081] In this way, the detection personnel can determine the tilt angle of the support plate 20 by the position of the support plate 20 relative to the angle gauge 130, which is convenient for the subsequent detection process.
[0082] In some examples, such as Figure 9 As shown, the inclinometer 130 and the first support base 40 are fixedly connected.
[0083] In some embodiments, as Figure 9 As shown, the detection device 2000 further includes a plurality of support bars 140 and a plurality of positioning blocks 150 .
[0084] A plurality of support bars 140 are located on a side of the support plate 20 away from the fixed plate 10 and are fixedly connected to the support plate 20. The plurality of support bars 140 extend along the third direction M3 and are spaced apart along the fourth direction M4. The support bars 140 are configured to support the display panel 100 and the printed circuit board 200 connected to the display panel 100. In this case, the support plate 20 is used to indirectly support the display panel 100 and the printed circuit board 200 connected to the display panel 100. The third direction M3 intersects the fourth direction M4. For example, the third direction M3 is perpendicular to the fourth direction M4.
[0085] In this manner, the support bars 140 can create a gap between the display panel 100 and the support plate 20 , and an inspector can more easily remove the display panel 100 through the gap.
[0086] A plurality of positioning blocks 150 are located on a side of the support plate 20 away from the fixed plate 10 and are fixedly connected to the support plate 20. The plurality of positioning blocks 150 are arranged around at least one support bar 140 and abut against the display panel 100. In a direction perpendicular to the support plate 20, the height of the positioning blocks 150 is greater than the height of the support bar 140.
[0087] Arranged in this manner, during the tilting of the support plate 20, multiple positioning blocks 150 can fix the display panel 100, which can reduce the risk of the display panel 100 moving back and forth or left and right, causing the display panel 100 to separate from the support bar 140, thereby reducing the risk of the display panel 100 being damaged due to collision with other objects.
[0088] In some embodiments, as Figure 9 As shown, the third direction M3 is parallel to the first direction M1. The plurality of support bars 140 include at least one first support bar 1401 and at least one second support bar 1402. The at least one second support bar 140 is located on one side of the at least one first support bar 1401 along the fourth direction.
