Description

Technical Field

[0001] This invention relates to the field of screen illumination and detection, and particularly to a screen connection and illumination detection device and method. Background Technology

[0002] In current screen production and testing processes, the screen needs to be powered on by connecting the flexible flat cable at the bottom of the screen. Screen testing is then performed by observing the illuminated screen. However, traditional testing methods largely rely on manual operation, which is not only inefficient but also prone to inaccurate results due to human error. This is especially true on large-scale production lines, where manual testing struggles to meet the demands for high efficiency and precision. Even with robotic arms, inaccurate connections can occur due to the flat cable's location at the bottom of the screen. Therefore, developing an automated, efficient, and accurate screen connection and illumination testing device and method has become a pressing issue in the current screen production and testing field.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, embodiments of this application disclose a screen insertion and lighting detection device, including a frame 1, a transmission device 2 disposed below the frame 1, a fixture 3 for placing products disposed on the transmission device 2, a detection camera 4 for detecting the screen after it is lit disposed on the top of the frame 1, a needle film crimping mechanism 5 for pressing the detection end of the product's flexible flat cable disposed below the frame 1, and a suction and feeding component 6 disposed on one side of the needle film crimping mechanism 5 for picking up the flexible flat cable on the back of the product and inserting it into the needle film crimping mechanism 5.

[0041] In practice, the product is first placed on fixture 3, and the conveyor 2 is activated to smoothly transport fixture 3 and the product on it to a designated position below the inspection camera 4. Next, the suction and feeding assembly 6 picks up the flexible flat cable on the back of the product and plugs it into the needle film crimping mechanism 5. Then, the needle film crimping mechanism 5 crimps the signal end of the flexible flat cable to energize it, causing the screen to light up. Then, the inspection camera 4 inspects the lit screen.

[0042] This device, through the inclusion of a transmission device 2, a fixture 3, a detection camera 4, a needle film crimping mechanism 5, and a suction and feeding assembly 6, achieves automatic insertion and lighting detection of the flexible flat cable at the bottom of the screen, greatly improving detection efficiency and accuracy. Simultaneously, the cooperation between the suction and feeding assembly 6 and the smoothing mechanism allows the suction and feeding assembly 6 to accurately pick up the end of the flexible flat cable and deliver it to the needle film crimping mechanism 5.

[0043] In this embodiment, as Figure 4 As shown, a smoothing mechanism for smoothing the soft ribbon cable at the bottom of the product is also provided on one side of the suction and feeding assembly 6.

[0044] Specifically, before adsorption, the smoothing mechanism will smooth and flatten the soft flat cable at the bottom of the product, so that the subsequent suction and feeding component 6 can accurately pick up the soft flat cable from the bottom.

[0045] In this embodiment, as Figure 4 As shown, the smoothing mechanism includes a smoothing block 72 and a first drive cylinder 71 for driving horizontal movement, and also includes a second drive cylinder 73 for driving the smoothing block 72 to move up and down.

[0046] Specifically, when it is necessary to smooth the flexible flat cable, the second drive cylinder 73 first drives the smoothing block 72 to rise to a suitable height so that it can contact the flexible flat cable at the bottom of the product. Then, the first drive cylinder 71 drives the smoothing block 72 to move horizontally to smooth the flexible flat cable, ensuring that the flexible flat cable is flat and easy for the subsequent feeding component 6 to pick up accurately.

[0047] In this embodiment, as Figure 2 As shown, the suction and feeding assembly includes a first mounting plate 61, a rotary drive mechanism 62 is provided at the upper end of the first mounting plate 61, a suction head assembly 63 is provided at the driving end of the rotary drive mechanism 62, a positioning camera 64 for detecting the position of the end of the product flexible flat cable is provided at the lower end of the first mounting plate 61, and also includes a first XYZ drive module 65 for driving the first mounting plate 61 to move.

[0048] Specifically, during the feeding process, the positioning camera 64 first accurately detects the end position of the product's flexible flat cable and feeds the position information back to the control system. Based on the feedback, the control system directs the first XYZ drive module 65 to adjust the position of the first mounting plate 61, so that the suction head assembly 63 moves accurately below the end of the flexible flat cable. Subsequently, the rotation drive mechanism 62 adjusts the angle of the suction head assembly 63 as needed to ensure that the suction head 633 can pick up the flexible flat cable in the optimal posture. After picking up the cable, the first XYZ drive module 65 drives the first mounting plate 61 to descend and retract. When the needle film crimping mechanism 5 is in place, the first XYZ drive module 65 drives the first mounting plate 61 to move again, accurately delivering the flexible flat cable to the needle film crimping mechanism 5, preparing for subsequent insertion and power-on.

[0049] In this structure, the coordinated operation of the positioning camera 64, the first XYZ drive module 65, and the rotation drive mechanism 62 effectively improves the automation level and detection accuracy of screen insertion and lighting detection.

[0050] In this embodiment, as Figure 3 As shown, the suction head assembly 63 includes a suction head mounting plate 631, an arc-shaped plate 632 on the suction head mounting plate 631, a first mounting hole on the arc-shaped plate, and a suction head 633. The suction head 633 has mounting blocks 634 at both ends, and the mounting blocks 634 have second mounting holes that cooperate with the first mounting hole, so that the suction head 633 and the arc-shaped plate can be detachably connected.

[0051] Specifically, the suction head 633 and the arc-shaped clamp are detachably connected, greatly facilitating the replacement and maintenance of the suction head 633. In practical applications, the appropriate suction head 633 can be quickly replaced according to the specifications of the flexible flat cable and the testing requirements of different products, thereby ensuring the stability and accuracy of the suction operation. This design not only improves the flexibility of the device but also reduces maintenance costs and time.

[0052] In this embodiment, as Figure 5 and Figure 6 As shown, the needle membrane pressing mechanism 5 includes a second mounting plate 51, on which an upper needle membrane 54 assembly and a lower pressing assembly that cooperate with the upper needle membrane 54 assembly are respectively provided, and also includes a third driving cylinder 52 for driving the second mounting plate 51 to perform lifting and lowering movements.

[0053] Specifically, the upper needle membrane 54 assembly includes an upper needle membrane mounting block 53, with the upper needle membrane 54 disposed at the bottom of the upper needle membrane mounting block 53, and also includes a fourth drive cylinder 55 for driving the upper needle membrane mounting block 53 to move horizontally; the lower pressing assembly includes a lower pressing block 56, with a protrusion 57 disposed on the lower pressing block 56, and also includes a fifth drive cylinder 58 for driving the lower pressing block 56 to move horizontally and a sixth drive cylinder 59 for driving the lower pressing block 56 to move vertically. When the fifth cylinder and the sixth cylinder drive the lower pressing block 56 to move into position, the protrusion 57 and the upper needle membrane 54 are aligned and engaged.

[0054] During the needle film crimping operation, the third drive cylinder 52 first drives the second mounting plate 51 to rise to a suitable height, placing the upper needle film 54 assembly and the lower crimping assembly in an easily operable position. Then, the upper needle film 54 assembly extends under the drive of the fourth drive cylinder 55. Next, the suction and feeding assembly 6, driven by the first XYZ drive module 65, accurately delivers the sucked-up flexible flat cable to the upper needle film 54 assembly. At this time, the positioning camera 64 positions the upper needle film 54 assembly and the end of the flexible flat cable, and fine-tunes the suction head assembly 63 through the first XYZ drive module 65 and the rotary drive mechanism 62 to ensure accurate alignment and connection between the signal end of the flexible flat cable and the upper needle film 54 assembly. After alignment, the fifth drive cylinder 58 and the sixth drive cylinder 59 drive the lower crimping block 56 to move, causing the protrusion 57 to press the signal end of the flexible flat cable against the upper needle film 54 assembly, thereby energizing the flexible flat cable and lighting up the screen.

[0055] The above structure achieves a high degree of automation and precision, effectively avoiding errors and instabilities that may be caused by manual operation.

[0056] In this embodiment, as Figure 7 As shown, the frame 1 is equipped with a light source assembly 8 for illuminating the product.

[0057] Specifically, the light source assembly 8 includes a light source mounting bracket 81, and strip light sources 82 are respectively arranged around the inner perimeter of the light source mounting bracket 81. When the product moves to the area below the detection camera 4, the light source assembly 8 is located around the upper part of the product.

[0058] During testing, the light source assembly 8 is turned on, and the bar light source 82 emits uniform light, illuminating all areas of the screen and providing a clear, shadow-free shooting environment for the inspection camera 4. This design ensures that the inspection camera 4 can capture every detail of the screen, achieving accurate testing. At the same time, the bar light sources 82 arranged around the perimeter effectively avoid reflections and glare caused by direct light, further improving the accuracy and reliability of the testing.

[0059] This invention also discloses a screen insertion and power-on detection method, which uses the screen insertion and power-on detection device described above and includes the following steps:

[0060] S100: The product is loaded onto fixture 3;

[0061] S200: The transmission device 2 drives the product to move below the detection camera 4;

[0062] S300: The smoothing mechanism abuts and smooths the soft ribbon cable at the bottom of the product, the positioning camera 64 detects the end position of the soft ribbon cable, the suction head assembly 63 picks up the soft ribbon cable and moves downward and backward, while the smoothing mechanism retracts.

[0063] S400: The third drive cylinder 52 drives the upper needle membrane 54 assembly and the lower pressing assembly to rise, and the fourth drive cylinder 55 drives the upper needle membrane 54 assembly to extend.

[0064] S500: The first XYZ drive module 65 drives the suction head assembly 63 to move the flexible flat cable to the upper needle film 54 assembly. At the same time, the positioning camera 64 positions the cable. The first XYZ drive module 65 and the rotary drive mechanism 62 adjust the position of the suction head assembly 63 so that the signal end of the flexible flat cable is aligned and connected with the upper needle film 54 assembly.

[0065] S600: The fifth drive cylinder 58 and the sixth drive cylinder 59 drive the lower pressing block 56 to move, so that the protrusion block 57 presses the signal end of the flexible flat cable against the upper needle film 54 component, the flexible flat cable is powered on, and the screen lights up.

[0066] S700: The detection camera 4 detects the screen after it is turned on.

[0067] Specifically, in step S300, when performing the smoothing operation, the second drive cylinder 73 first drives the smoothing block 72 to rise to a suitable height so that it can contact the soft ribbon cable at the bottom of the product, and then the first drive cylinder 71 drives the smoothing block 72 to move horizontally to smooth the soft ribbon cable.

[0068] This method achieves precise connection and lighting detection of the flexible cable at the bottom of the screen through close coordination and automated control of each step.

[0069] Specifically, in step S300, the smoothing mechanism provides strong support for the accurate pick-up of the suction head assembly 63. Subsequently, after picking up the flexible flat cable, the suction head assembly 63 retracts downwards, while the smoothing mechanism retracts, making room for the subsequent needle film crimping operation. In step S500, the fine adjustment of the first XYZ drive module 65 and the rotary drive mechanism 62 ensures accurate alignment and connection between the signal end of the flexible flat cable and the upper needle film assembly 54, thus guaranteeing precise subsequent docking. In step S600, driven by the fifth drive cylinder 58 and the sixth drive cylinder 59, the lower pressing block 56 presses the signal end of the flexible flat cable against the upper needle film assembly 54, energizing the flexible flat cable and lighting up the screen. Finally, in step S700, the inspection camera 4 performs a comprehensive inspection of the lit screen, ensuring that the screen's quality and performance meet the standard requirements. Therefore, the entire inspection method of this application is efficient and accurate, greatly improving the efficiency and reliability of screen inspection.
