Description

Technical Field

[0001] This utility model pertains to measuring equipment, and more particularly relates to a fully automatic light strip detection device. Background Technology

[0002] In the development of the LED industry, optical parameter testing is necessary to ensure products meet certain specifications and quality levels. In the past, the lack of comprehensive national and industry standards led to significant disputes among manufacturers, users, and research institutions, which negatively impacted the development of the domestic LED industry. Testing optical parameters such as luminous flux, luminous efficiency, radiant flux, radiant efficiency, luminous intensity, luminous intensity distribution characteristics, and spectral parameters ensures products meet certain quality standards, contributing to the healthy development of the industry. Furthermore, optical parameter testing results can provide a basis for improving LED manufacturing processes. For example, if the luminous flux of a batch of LED products is lower than expected, manufacturers can analyze various aspects of the production process, such as raw material quality, chip manufacturing processes, and packaging processes, to identify potential problems and make improvements, thereby enhancing the overall quality and performance of the products. Therefore, LED strip testing also plays a crucial role in quality control.

[0003] Chinese patent document CN205139181U discloses an LED photoelectric characteristic measuring instrument, including a movable test platform for mounting an LED strip to be tested, a light receiving device disposed above the LED strip, an integrating sphere connected to the output end of the light receiving device for measuring light, and a display for displaying the measurement results of the integrating sphere; the LED strip is uniformly provided with multiple LEDs. The LED strip is clamped onto the movable test platform. After power is applied, the light receiving device transmits light to the integrating sphere, which analyzes and measures the light. The brightness result is displayed on the screen. After the measurement is completed, the test platform moves forward, positioning the next LED below the light receiving device, thus continuing to test the photoelectric characteristics of the next LED.

[0004] With the continuous development of the LED industry, the light-emitting position of LED light strips is no longer limited to the front of the strip; for example, some LED light strips also emit light from the side. Furthermore, the arrangement of LED light strips is no longer limited to uniform distribution, but is instead used in uneven and irregular arrangements to meet the differentiated needs of various industries. Therefore, the aforementioned patented solutions no longer meet actual usage requirements. Utility Model Content

[0005] To overcome the technical problem that existing LED strip testing equipment can only detect LEDs that are uniformly distributed and emit light from the front on the LED strip, but cannot detect LEDs that are irregularly and unevenly distributed and emit light from the side on the LED strip, one objective of this utility model is to provide a fully automatic LED strip testing device. This device uses a rectangular slot, and the LED strip is positioned on the side wall or bottom of the slot according to its emission direction to ensure that the emission direction is aligned with the testing device. Simultaneously, supplementary lighting and a camera are used to sequentially detect and record the position of each LED in a dark chamber, providing the data to an integrating sphere for positional reference, allowing the integrating sphere to sequentially detect the emission status of the LEDs.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a fully automatic light strip detection device, comprising a light-shielding shell; an X-axis slider slidably connected to the inner top of the light-shielding shell; a Y-axis slider slidably connected to the inner bottom of the light-shielding shell, the sliding direction of the Y-axis slider being perpendicular to the sliding direction of the X-axis slider; an integrating sphere disposed at the lower end of the X-axis slider; and a mounting plate disposed at the upper end of the Y-axis slider; wherein, a rectangular groove is provided at the upper end of the mounting plate, the length direction of the rectangular groove being along the sliding direction of the X-axis slider, and the light strip can be selectively mounted on the side wall or inner bottom of the rectangular groove; a ring-shaped supplementary light is provided at the lower end of the X-axis slider; a camera is provided at the lower end of the X-axis slider; and the camera is located in the center of the ring of the supplementary light.

[0007] The light-shielding shell forms a dark chamber. The X-axis slider drives the camera to slide along the rectangular groove. The camera records the position of each LED on the light strip visually. Subsequently, the X-axis slider drives the integrating sphere to slide along the rectangular groove. Based on the position information of the LEDs recorded by the camera, the integrating sphere is made to stop directly above each LED in sequence to detect the luminous parameters.

[0008] Furthermore, an installation plate is provided on the integrating sphere, and the installation plate is longitudinally slidably connected to the X-axis slider; a fine-tuning knob is rotatably connected to the upper end of the X-axis slider, and the fine-tuning knob is threadedly connected to the installation plate.

[0009] Depending on the object being detected, the relative distance between the integrating sphere and the object can be adjusted by rotating the fine-tuning knob.

[0010] Furthermore, the inner wall of the light-shielding shell is provided with a non-reflective treatment layer; the non-reflective treatment layer is blackened by means of painting or other methods; the supplementary light is an infrared lamp.

[0011] Furthermore, the Y-axis slider is provided with multiple pairs of adjustment plates; in one pair of adjustment plates, a fixed block is provided at the upper end of one adjustment plate, and a movable block is slidably connected to the upper end of the other adjustment plate; the mounting plate is detachably connected between the fixed block and the movable block.

[0012] Specifically, the upper end of the movable block is symmetrically provided with two waist-shaped holes, and the length direction of the waist-shaped holes is set along the sliding direction of the movable block.

[0013] Specifically, the movable block has an L-shaped structure, and the long side of the L-shaped structure abuts against the mounting plate.

[0014] Furthermore, the lower front end of the light-shielding shell is provided with a lower opening, which is directly opposite to the Y-axis slider; a flap is rotatably connected to the lower end of the lower opening, which can selectively close the lower opening; the Y-axis slider slides out of the light-shielding shell through the lower opening.

[0015] Furthermore, the upper front end of the light-shielding shell is provided with an upper opening; two cabinet doors are symmetrically arranged inside the upper opening, and the side wall of the upper opening is rotatably connected to the side of the cabinet door.

[0016] The light strip on the mounting plate can be replaced through the lower opening; the light shield can be adjusted or debugged through the upper opening.

[0017] Specifically, the outer wall of the light-shielding shell is rotatably connected to a keyboard and mouse tray, the rotation axis of the keyboard and mouse tray is longitudinally arranged and located on one vertical side of the keyboard and mouse tray; the outer wall of the light-shielding shell is provided with a cantilever, and the end of the cantilever is provided with a display.

[0018] Specifically, a platform is horizontally arranged inside the light-shielding shell, and the Y-axis slider is slidably connected to the upper end of the platform; a gantry frame is arranged at the upper end of the platform; and the X-axis slider is slidably connected to the upper part of the gantry frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By setting rectangular slots on the mounting plate, the mounting method of the light strip can be flexibly adjusted according to the light emission direction of the LEDs on the light strip, so that the light emission direction is upward, which facilitates the operation of the testing equipment and increases the applicability of the equipment.

[0021] 2. By setting up a camera, machine vision is used to locate and record the positions of irregular and unevenly distributed LEDs on the light strip, providing a reference for the detection position of the integrating sphere. This allows the integrating sphere to automatically hover above the LEDs sequentially to detect their illumination. This automated process reduces manual workload and improves detection efficiency.

[0022] 3. By setting up a light-shielding shell and using an infrared supplementary light to provide a light source for the camera, the influence of external light sources is reduced, resulting in more accurate detection results. Attached Figure Description
