Description

Technical Field

[0001] This application relates to the field of lighting fixture testing technology, and more specifically, to an automatic testing device for fire emergency sign lights. Background Technology

[0002] The standards for fire emergency sign lights specify requirements for brightness. During the production and testing of these lights, it is necessary to check whether the brightness meets these requirements. In actual production and testing, brightness meters and darkrooms are used, with manual testing of individual products. This method is inefficient, requires frequent maintenance, and is prone to errors such as incorrect nameplate labeling.

[0003] A search revealed that Chinese patent CN221198888U discloses a brightness detection device for fire emergency lighting fixtures. This device limits the position of the lighting fixture by using a limiting clamp, and facilitates the adjustment of the lighting fixture's position through the cooperation of gears and an external gear ring. It can adjust the position of the lighting fixture in multiple directions, realizing multi-directional detection of the lighting fixture, improving the accuracy of the lighting fixture brightness detection, and achieving the goal of improving the practicality of the brightness detection device for fire emergency lighting fixtures.

[0004] The aforementioned device cannot continuously detect the brightness of the lamps, requiring manual assistance, resulting in low efficiency in detecting lamp brightness. Therefore, we propose an automatic detection device for fire emergency sign lights. Utility Model Content

[0015] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0016] Please see Figure 1 and Figure 2 This application provides an automatic detection device for fire emergency sign lights, including a support base 1. Two parallel guide rails 2 are fixedly mounted on the upper part of the support base 1. A conveyor belt 3 is mounted above the guide rails 2. A carrier 4 is positioned between the two guide rails 2 and placed above the conveyor belt 3. The carrier 4 is equipped with a power interface 401, which contains a conductive element. A bracket 5 is fixedly mounted on the upper part of the support base 1. A dark box 6 is slidably connected to the bracket 5. A luminance meter 601 is mounted on the dark box 6, which is located above the carrier 4. A lifting cylinder 7 is installed between the bracket 5 and the dark box 6. A jacking cylinder 8 is located between the two guide rails 2 and below the dark box 6 and the carrier 4. A power-on pin 9 is mounted on the upper part of the support base 1. The power-on pin 9 is plugged into the power interface 401 and electrically connected to the conductive element.

[0017] The lamp is placed on the carrier 4, and the lamp's bus is inserted into the power interface 401 and electrically connected to the conductive element. The carrier 4 is then placed between two guide rails 2, and the carrier 4 is driven by the conveyor belt 3 to move towards the dark box 6. When the carrier 4 moves directly under the dark box 6, the lifting cylinder 7 pushes the carrier 4 upward, causing it to disengage from the conveyor belt 3. The lifting cylinder 7 then moves the dark box 6 downward, so that the dark box 6 covers the lamp. The power-on pin 9 is inserted into the power interface 401 and electrically connected to the conductive element to supply power to the lamp. The brightness of the lamp is detected by the luminance meter 601. After the detection is completed, the power-on pin 9, the dark box 6, and the carrier 4 are reset in sequence, and the carrier 4 is driven by the conveyor belt 3 to move to the next work station.

[0018] like Figure 3 , Figure 4 and Figure 5 As shown, the upper part of the carrier 4 has two mounting slots 402, which can hold two lamps at the same time, increasing the detection efficiency; one end of the power interface 401 is located on the upper part of the carrier 4, and the other end is located on the side of the carrier 4; preferably, there are two power interfaces 401, which are located on both sides of the carrier 4 respectively; a power supply cylinder 10 is fixedly installed on the support base 1, and there are two power supply cylinders 10, which are respectively located on the outside of the two power interfaces 401. The power supply pin 9 is fixedly installed on the telescopic end of the power supply cylinder 10, and the power supply pin 9 is located above the guide rail 2.

[0019] After the lifting cylinder 7 pushes the carrier 4 upward, causing the carrier 4 to detach from the conveyor belt 3, the power supply cylinder 10 is extended to push the power pin 9 into the power interface 401 to supply power to the lamp; after the test is completed, the power supply cylinder 10 is reset to pull out the power pin 9.

[0020] Preferably, the conductive element is a metal spring, which can increase the stability of the electrical connection between the conductive element and the power-on pin 9 and the lamp bus.

[0021] Preferably, a limiting module 11 is provided below the dark box 6. The limiting module 11 is fixedly installed on the upper part of the support base 1. The limiting module 11 can block the carrier 4 below the dark box 6 and can obtain the position information of the carrier 4 through the limiting module 11, which is used to control the dark box 6 and the state of the power-on pin 9, facilitating the detection of the lamp. After the lamp detection is completed, the limiting module 11 can release the carrier 4. The limiting module 11 can use a micro switch or an infrared sensor to obtain the position information of the carrier 4, and the limiting module 11 can limit the carrier 4 by magnetic force or mechanical fixation.
