DETAILED DESCRIPTION

[0025] The core of the utility model is to disclose a lamp board detection tool to accurately plug the lamp board with terminals and LED particles in the same direction with the probe, thereby improving the accuracy of lamp board performance detection.

[0026] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0027] See also Figure 1 , Figure 2 and Figure 3The lamp board detection tooling provided by the embodiment of the utility model includes a base plate 10, a contoured carrier plate 20, a first driving unit, a plug connector 50 and a lamp board driver 60, wherein the base plate 10 serves as a supporting structure to provide a flat setting position for other structural components, and the contoured carrier plate 20 is fixedly arranged on the base plate 10 to carry the lamp board to be inspected. The purpose of setting the contoured carrier plate 20 is to adapt the shape structure of the lamp board to stably fix the lamp board and avoid the displacement of the lamp board during plugging in and causing plugging failure. It should be noted that the setting of the contoured carrier plate 20 and the lamp board here refers to the fact that the lamp board can be stably limited and fixed when it is set on the contoured carrier plate 20.

[0028] On this basis, when the light board is adapted to be arranged on the contoured carrier 20, its terminals will be arranged toward the first driving part, and the first driving part is transmission-connected with the probe 40 to drive the probe 40 to move when the first driving part drives, and preferably the first driving part drives the probe 40 along a straight line in a driving path to reduce the driving difficulty and structural complexity, and the risk of failure of the linear motion of the probe 40 is small, and the path of the probe 40 will at least pass through the position for plugging in the light board terminals. On the basis of this structure, when the first driving part is not started, the probe 40 is spaced apart from the light board, and after the first driving part is started, the probe 40 moves toward the light board and can be plugged in with the terminals of the light board.

[0029] The plug connector 50 is used to connect to an external power source, and the plug connector 50 is electrically connected to the probe 40 and the light board driver 60. It should be noted that the electrical connection here refers to an electrical connection, that is, when the plug connector 50 is powered on, current passes synchronously through the probe 40 and the light board driver 60. The light board driver 60 is a driving program for the light board when it is powered on and lit. The operator can turn on the first drive unit and the external power supply equipment of the plug connector 50 at a position away from the light board detection tooling to complete the connection between the probe 40 and the light board terminal, and capture images through the lighting camera under the light board to compare and analyze the lighting effect of the light board.

[0030] The lamp board detection tooling provided by the embodiment of the utility model can, when plugging the lamp board whose terminals and LED particles are in the same direction with the probe 40, enable the operator to drive the external power supply device of the first driving part and the plug connector 50 at a position far away from the detection tooling to achieve the plugging of the probe 40 with the lamp board terminal, and transmit current to the lamp board through the probe 40 so that the lamp board is lit and detected. The process is simple and will not cause glare problems due to manual plugging by employees. At the same time, the operator can start the first driving part alone without starting the external power supply, and observe and adjust the position of the plugging effect of the probe 40 and the lamp board terminal. After confirming that the probe 40 and the terminal can be effectively plugged, start the external power supply device of the first driving part and the plug connector 50 at a distance to ensure the effective plugging effect of the probe 40 and the lamp board terminal during formal testing, thereby reducing the loss of testing costs caused by plugging failure.

[0031] Taking into account that during the detection of the light board, the external light source may have a certain impact on the accuracy of the light board detection, in some embodiments of the present invention, the light board detection tooling also includes a light shielding box 110, which is a box structure with an opening at the top, and a cover plate 120 is arranged on the top of the light shielding box 110 to open and close the light shielding box 110, and the contoured carrier 20 is arranged in the light shielding box 110, and the light board can be placed in the box body from the top opening of the light shielding box 110 when the cover plate 120 is opened, and the cover plate 120 will cooperate with the contoured carrier 20 when it is closed, so as to press the light board from the upper and lower sides so that the light board is stably set in a preset position, and when the cover plate 120 is closed, the light shielding box 110 is in a dark room state to isolate the influence of external light sources; it should be noted that it is preferred to also arrange the first driving unit inside the light shielding box 110, so that the light shielding box 110 maintains a good light shielding effect,

[0032] Furthermore, in some embodiments of the utility model, the first driving part adopts the cylinder 30 as the power source, so as to have the advantages of fast response speed and high control accuracy. Correspondingly, the probe 40 is arranged on the extension rod 310 of the cylinder 30, so that it can move quickly and accurately and plug into the lamp board terminal under the action of the cylinder 30; at the same time, the base plate 10 is designed with a special pipe connector 70 for receiving high-pressure gas. The pipe connector 70 is connected to the air pipe connector 320 of the cylinder 30 to ensure that the high-pressure gas can reach the cylinder smoothly, so that the cylinder 30 can operate stably under various working conditions. The above structure not only improves the detection efficiency, but also can improve the safety and reliability of the operation process of the detection tooling.

[0033] In order to facilitate the adjustment of the position of the probe 40 so that the detection tooling can adapt to the detection of lamp boards of different sizes, in a specific embodiment of the utility model, the fixing structure of the probe 40 is designed to be adjustable, specifically, a support seat 330 is fixedly provided on the extension rod 310, and a fixing block 340 for setting the probe 40 is installed on the support seat 330. The fixing block 340 is slidably set on the support seat 330 and can be slidably connected by a slide rail, or a gear rack and other structures. At the same time, the fixing block 340 has at least two fixed positions on the support seat 330, so that the probe 40 can be fine-tuned according to the detection requirements to adapt to lamp board terminals of different models and sizes. The above structure can greatly improve the applicability and flexibility of the tooling.

[0034] It should be noted that the sliding path of the fixing block 340 is the connection direction of the terminals on the lamp board of different sizes, so that the probe 40 can be adapted to the terminals of the lamp board at different positions by adjusting the fixing block 340 .

[0035] On the basis of the above-mentioned embodiment, in order to ensure the stability and fixing accuracy of the probe 40, the utility model also designs a novel connection method between the fixing block 340 and the support seat 330, which is specifically that at least two positioning holes are spaced apart on the support seat 330, and the fixing block 340 is provided with a mounting groove and a locking hole. The probe 40 passes through the mounting groove for fixed setting, and the locking hole is used to align the single positioning hole. After the locking hole of the fixing block 340 is aligned with the positioning hole of the support seat 330, the locking hole and the positioning hole in the aligned state are passed through the bolt to realize the fixed connection between the fixing block 340 and the support seat 330. When the position of the probe 40 needs to be adjusted, it is only necessary to pull out the bolt, and move the fixing block 340 until its locking hole is aligned with other positioning holes on the support seat 330, and then fix it with the bolt. The above-mentioned connection method is simple and reliable, ensuring the stability and precise positioning of the probe 40 during the detection process.

[0036] In order to further optimize the above technical solution, in a preferred embodiment of the present invention, the fixed block 340 is made of acrylic material to have good transparency and stability. At the same time, two fixed blocks 340 are arranged at intervals on the support seat 330, which not only facilitates the operator to observe and adjust the position of the probe 40, but also can adapt to light boards with single or two plug-in terminals, thereby improving the versatility of the detection tooling.

[0037] Since the lamp board inspection tool provided in the embodiment of the utility model is often placed on metal machinery and equipment to perform lamp board performance inspection, in order to facilitate the fixed setting of the inspection tool, the lamp board inspection tool provided in the embodiment of the utility model is provided with a fixed magnet 80 on the bottom surface or side wall of the base plate 10, so that the tool can be conveniently fixed on various metal workbenches by magnetic force, and at the same time, in order to protect the fixed magnet 80 and the workbench, the outer periphery of the fixed magnet 80 is wrapped with an anti-collision layer to prevent the fixed magnet 80 from being damaged by collision.

[0038] In a specific embodiment of the present invention, the anti-collision layer is made of rubber or sponge material to have good cushioning performance and wear resistance. At the same time, at least two fixed magnets 80 are arranged on the bottom plate 10 at intervals to help evenly disperse the magnetic force, reduce the pressure on the workbench and maintain the stable setting of the detection tooling.

[0039] Furthermore, the light board detection tooling provided in the embodiment of the utility model adopts an aviation plug as the plug connector 50. This high-performance connector has excellent electrical performance and environmental adaptability, and the aviation plug can maintain stable signal transmission in harsh working environments and is suitable for high-frequency plugging and unplugging operations, thereby improving the durability and maintenance convenience of the tooling.

[0040] In order to improve the portability and operating comfort of the light board detection tooling, handles 90 are designed on both sides of the top surface of the base plate 10 in the embodiment of the utility model. The design of the handles 90 takes into account the principles of ergonomics, so that the operator can easily carry and position the tooling, reducing labor intensity. In addition, the shape and size of the handles 90 are also designed to adapt to the hand shape and grip strength of different operators, thereby improving the comfort of use.

[0041] Through the above detailed technical description and embodiments, the lamp board detection tooling provided by the embodiments of the utility model shows significant advantages in structural design, function realization, operational convenience and safety. This tooling can not only improve the efficiency and accuracy of lamp board detection, but also maintain stable and reliable performance under various working conditions. It has high practical value and market potential.
