Abstract
Description
Technical Field
[0001] This invention relates to the field of LED backlight panel testing technology, and in particular to a cable clamping fixture and an LED backlight panel testing device. Background Technology
[0002] LED backlight panels are widely used in display modules, automotive displays, industrial displays and related lighting components. During the production, assembly, debugging and factory testing processes, it is usually necessary to conduct power-on tests on the LED backlight panels to confirm whether there are any problems such as the product not lighting up, partially not lighting up, abnormal brightness, or abnormal electrical performance.
[0003] In existing technologies, a common method involves inspectors manually connecting the backlight panel to a power source or testing fixture and directly observing whether it lights up, then relying on experience to determine if any abnormalities exist. While this method is simple to implement, it is inefficient. Furthermore, because the positions of the two leads of the LED backlight panel are not fixed, automatic detection cannot be used to connect the two lead contacts of the LED backlight panel.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0005] This invention provides a cable clamping fixture and an LED backlight panel testing device, thereby effectively solving the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this invention is: a cable clamping fixture, comprising:
[0007] The testing plane is used to place the LED backlight panel to be tested, and
[0008] A flip-pressing assembly is located at one end of the detection plane. It is flip-configurable and includes a first flip state in which the flip-pressing assembly is attached to the detection plane to press the LED backlight panel.
[0009] A flip-up cable management assembly is disposed at the other end of the detection plane. It can be flipped and includes a second flip state. The cable management assembly is provided with a comb structure. In the second flip state, the comb structure is located at the LED backlight panel lead wire. The comb structure can move linearly along the direction of the LED backlight panel lead wire to manage the LED backlight panel cable.
[0010] Furthermore, one end of the flip-pressing assembly is provided with a first flip structure, and the other end is provided with a first pressing assembly. The first pressing assembly flips from the first flip structure to the first flip state to press the LED backlight panel.
[0011] Furthermore, the first clamping component has a clamping plate at one end near the detection plane, and the clamping plate has a flexible material on the side that is in contact with the LED backlight panel.
[0012] Furthermore, the first pressing component is provided with an elastic element, which is located at the end of the pressing plate away from the LED backlight panel. The elastic element provides elastic support to the pressing plate so that when the pressing plate presses against the LED backlight panel, the pressing force does not exceed a set threshold.
[0013] Furthermore, it also includes a wire gathering assembly, which is disposed at one end of the flip-up wire management assembly. The wire gathering assembly includes two wire gathering plates, which move linearly in a direction perpendicular to the LED backlight panel leads to gather the two LED backlight panel leads into the comb structure range.
[0014] Furthermore, the flipping cable management assembly includes:
[0015] A second flip structure is disposed at one end away from the detection plane;
[0016] A linear module is disposed at one end near the detection plane, and the comb structure is disposed on the linear module, which drives it to move linearly along the direction of the LED backlight panel lead wire.
[0017] Furthermore, a plurality of grooves are provided on the detection plane corresponding to the comb tooth structure, so that the comb tooth structure can be inserted into the detection plane.
[0018] Furthermore, the comb structure is provided with a plurality of comb grooves, and the comb grooves are arched structures.
[0019] Furthermore, it also includes a lateral positioning component, which is disposed at the end of the detection plane away from the flipping cable management component. It moves linearly in the direction of approaching or away from the flipping cable management component, and after the LED backlight panel placed on the detection plane is laterally pushed to position it, the flipping pressing component presses it.
[0020] This invention provides an LED backlight panel testing device, comprising:
[0021] As mentioned above, the cable clamping fixture and
[0022] The detection frame is disposed on the top of the wire clamping fixture and includes a three-axis moving module, which can move laterally along the x, y, and z axes.
[0023] The finished product frame is located at one end near the flipping and pressing assembly, and the finished product frame includes at least two receiving slots to respectively accommodate qualified or unqualified parts.
[0024] The beneficial effects of this invention are as follows: By setting up a flip-and-press component and a flip-and-organize component, the backlight board can be quickly positioned and pressed, and the leads can be automatically organized before the LED backlight board is inspected, preventing the backlight board from shifting during the inspection process and improving inspection stability. Simultaneously, by utilizing the comb structure moving along the lead direction, disordered leads can be separated and organized, making the lead positions more uniform and facilitating subsequent automatic clamping, automatic power-on, and automatic inspection. This effectively solves the problem of difficulty in automatic docking due to the non-fixed position of the leads in the prior art. This fixture has a simple structure and is easy to operate, significantly improving the automation level, inspection efficiency, and inspection consistency of LED backlight board inspection.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0034] like Figures 1 to 6 As shown: A cable clamping fixture, comprising:
[0035] Detection plane 1 is used to place the LED backlight panel to be tested, and
[0036] The flip-pressing component 2 is located at one end of the detection plane 1. It can be flipped and includes a first flip state. In the first flip state, the flip-pressing component 2 is attached to the detection plane 1 to press the LED backlight panel.
[0037] The flip-up cable management component 3 is located at the other end of the detection plane 1. It can be flipped and includes a second flip state. The cable management component is provided with a comb structure 31. In the second flip state, the comb structure 31 is located at the LED backlight board lead wire. The comb structure 31 can move linearly along the LED backlight board lead wire direction to manage the LED backlight board cable.
[0038] By setting up the flip-and-press component 2 and the flip-and-sort-wire component 3, the backlight board can be quickly positioned and pressed, and the lead wires can be automatically sorted before the LED backlight board is inspected. This prevents the backlight board from shifting during the inspection process and improves inspection stability. Simultaneously, the comb structure 31, moving along the lead wire direction, can separate and organize the messy lead wires, making their positions more uniform. This facilitates subsequent automatic clamping, automatic power-on, and automatic inspection, effectively solving the problem of difficult automatic docking due to the non-fixed position of the lead wires in existing technologies. This fixture has a simple structure and is easy to operate, significantly improving the automation level, inspection efficiency, and inspection consistency of LED backlight board inspection.
[0039] In this embodiment, a first flip structure 21 is provided at one end of the flip-pressing component 2, and a first pressing component 22 is provided at the other end. The first pressing component 22 flips from the first flip structure 21 to the first flip state to press the LED backlight panel.
[0040] One end of the flip-and-press assembly 2 is provided with a first flip structure 21, and the other end is provided with a first pressing assembly 22. The first flip structure 21 can drive the first pressing assembly 22 to flip relative to the detection plane 1. When the flip-and-press assembly 2 flips to the first flip state, the first pressing assembly 22 presses down on the LED backlight panel, limiting and pressing the LED backlight panel, thereby improving the stability of the LED backlight panel during the wiring and detection process, and avoiding the impact on subsequent lead wire arrangement and automatic detection operations due to movement or tilting. At the same time, this flip-and-press method has a simple structure and is easy to operate, which can improve the adaptability and efficiency of the tooling.
[0041] As a preferred embodiment of the above, the first pressing component 22 is provided with a pressing plate 23 at one end near the detection plane 1, and the pressing plate 23 is provided with a flexible material on the side that is in contact with the LED backlight panel.
[0042] A clamping plate 23 is provided at one end of the first clamping component 22 near the detection plane 1. A flexible material is provided on the side of the clamping plate 23 that contacts the LED backlight panel. This flexible material, in contact with the LED backlight panel, ensures clamping stability while providing buffer protection to the LED backlight panel surface, preventing scratches, indentations, or localized damage caused by rigid clamping. This improves the tooling's adaptability to LED backlight panels of different specifications and enhances product protection during the testing process. Simultaneously, the flexible material can compensate for minor height differences on the backlight panel surface, improving clamping and bonding stability.
[0043] The first pressing component 22 is provided with an elastic element 24, which is located at the end of the pressing plate 23 away from the LED backlight. The elastic element 24 provides elastic support to the pressing plate 23 so that when the pressing plate 23 presses against the LED backlight, the pressing force does not exceed a set threshold.
[0044] The first clamping assembly 22 is provided with an elastic element 24, which is located on the side of the clamping plate 23 away from the LED backlight panel and provides elastic support to the clamping plate 23. When the clamping plate 23 presses against the LED backlight panel, the elastic element 24 provides buffering and elastic compensation, allowing the clamping plate 23 to clamp the LED backlight panel in a flexible manner, thereby avoiding excessive clamping force that could cause deformation, damage, or abnormal pressure on internal components of the LED backlight panel. Simultaneously, the elastic deformation of the elastic element 24 can limit the clamping force, keeping it within a set threshold range, improving clamping stability and product protection, and enhancing the tooling's adaptability to LED backlight panels of different thicknesses.
[0045] In this embodiment, a wire gathering component 4 is also included. The wire gathering component 4 is disposed at one end of the flip wire management component 3. It includes two wire gathering plates 41. The two wire gathering plates 41 move linearly in a direction perpendicular to the LED backlight board leads to gather the two LED backlight board leads into the range of the comb structure 31.
[0046] The wire gathering component 4 is located at one end of the flip-up wire organizing component 3 and includes two wire gathering plates 41 arranged opposite each other. The two wire gathering plates 41 can move linearly along the extension direction of the LED backlight panel leads to gradually gather the two scattered leads into the working range corresponding to the comb structure 31. By setting the wire gathering component 4, the scattered leads can be pre-gathered before the comb structure 31 performs wire organizing, reducing the spacing deviation and positional randomness between the leads, thereby improving the stability and success rate of the subsequent lead separation and arrangement by the comb structure 31, further improving the automatic wire organizing effect and the reliability of subsequent automatic detection.
[0047] As a preferred embodiment of the above embodiment, the flipping cable management component 3 includes:
[0048] The second flipping structure 32 is disposed at the end away from the detection plane 1;
[0049] A linear module 33 is disposed at one end near the detection plane 1, and a comb structure 31 is disposed on the linear module 33. The linear module 33 drives it to move linearly along the direction of the LED backlight board lead wire.
[0050] The flip-over cable management assembly 3 includes a second flip structure 32 and a linear module 33. The second flip structure 32 is located at the end furthest from the detection plane 1, and is used to drive the flip-over cable management assembly 3 to flip relative to the detection plane 1. The linear module 33 is located at the end closest to the detection plane 1. The comb structure 31 is mounted on the linear module 33 and is driven by the linear module 33 to move linearly along the extension direction of the LED backlight panel leads. Through the cooperation of the second flip structure 32 and the linear module 33, the comb structure 31 can be automatically pressed down and positioned, and the cable management operation can be automatically performed. This allows the comb structure 31 to stably enter the lead area and orderly comb the leads, improving cable management accuracy and automation. At the same time, the linear module 33 has stable movement and high control precision, which is beneficial to improving the adaptability of LED backlight panels of different specifications and the overall detection efficiency.
[0051] As a preferred embodiment of the above, a plurality of grooves 11 are provided on the detection plane 1 corresponding to the comb tooth structure 31, so that the comb tooth structure 31 is inserted into the detection plane 1.
[0052] Several grooves 11 are provided on the detection plane 1 at positions corresponding to the comb structure 31, so that the comb structure 31 can be inserted into the detection plane 1 during the wire arrangement process. By providing grooves 11, the comb structure 31 can be brought closer to or even partially pass through the area where the LED backlight panel leads are located, thereby improving the limiting, separation, and guiding effect on the leads, avoiding wire skipping, detachment, or cross-entanglement during the wire arrangement process, and improving the stability and accuracy of wire arrangement. At the same time, the grooves 11 also provide clearance space for the movement of the comb structure 31, reducing interference between the comb structure 31 and the detection plane 1, and improving the smoothness and reliability of the tooling operation.
[0053] Among them, the comb tooth structure 31 is provided with a number of comb tooth grooves 311, and the comb tooth grooves 311 are arched structures.
[0054] The comb structure 31 is provided with a plurality of comb grooves 311, which are arranged in an arched shape. By making the comb grooves 311 arched, a smoother guiding and limiting effect can be formed on the LED backlight board leads during the cable management process, reducing scratching, jamming, or bending when the leads come into contact with the comb structure 31, and reducing the risk of damage to the leads. At the same time, the arched structure facilitates the gradual entry of the leads into the corresponding comb grooves 311, improving the stability of lead separation and arrangement, making the cable management process smoother, thereby improving the overall automatic cable management effect and the reliability of subsequent automatic detection.
[0055] As a preferred embodiment of the above, it further includes a lateral positioning component 5, which is disposed at the end of the detection plane 1 away from the flipping cable management component 3. It moves linearly in the direction of approaching or away from the flipping cable management component 3, and after laterally pushing the LED backlight panel placed on the detection plane 1 to position it, the flipping pressing component 2 presses it.
[0056] The lateral positioning component 5 is located at the end of the detection plane 1 furthest from the flip-up cable management component 3, and can move linearly in the direction of approaching or moving away from the flip-up cable management component 3. After the LED backlight panel is placed on the detection plane 1, the lateral positioning component 5 pushes the LED backlight panel laterally, moving it to a preset positioning position, and then the flip-up clamping component 2 clamps and fixes it. By setting the lateral positioning component 5, the automatic alignment of the LED backlight panel can be achieved, reducing the error of manual placement, improving the positional consistency of the backlight panel during cable management and detection, thereby improving the accuracy of automatic cable management and the stability and reliability of subsequent automatic detection.
[0057] like Figure 7 As shown, this embodiment also includes an LED backlight panel detection device, comprising:
[0058] As mentioned above, the cable clamping fixture and
[0059] The detection frame 6 is set on the top of the wire clamping fixture and includes a three-axis moving module 61, which can move laterally along the x, y, and z axes.
[0060] The finished product frame 7 is located at one end near the flipping and pressing assembly 2, and the finished product frame 7 includes at least two receiving slots 71 to respectively receive qualified or unqualified parts.
[0061] By using the aforementioned wire clamping fixture in conjunction with the inspection frame 6, automatic positioning, wire arrangement, and inspection of LED backlight panels can be achieved. The three-axis moving module 61 can move along the x, y, and z directions. An inspection camera and / or electrical contact plate can be mounted on the three-axis moving module 61, enabling precise alignment and automated inspection of the LED backlight panels by the inspection mechanism, improving inspection flexibility and accuracy. Simultaneously, the finished product frame 7 is equipped with at least two receiving slots 71, which can separately classify and store qualified and unqualified parts after inspection, achieving integrated inspection and sorting, reducing manual intervention, improving overall inspection efficiency and automation, and making it suitable for large-scale continuous inspection scenarios of LED backlight panels.
