[0001] The utility model relates to the field of detection equipment, in particular to a device for testing a colorful light strip. Background Art
[0002] When producing TPV's unique colorful light strips, it is necessary to manually connect the hardware modules and rely on the naked eye to observe the lighting conditions to determine whether the product is defective. At the same time, the efficiency of inspecting one by one is low.
[0003] When testing the light bar, the matching hardware module needs to be connected with the test wire. The wiring is cumbersome, difficult to operate, and time-consuming. When producing TPV's unique and colorful light bar, each hardware module needs to be manually connected, and the product needs to be judged by human eyes to see the light condition. At the same time, the efficiency of one-by-one testing is low. During the test process, the light bar relies on human eyes to judge, and can only intercept some basic types of defects. At the same time, the human eye sees the LED light condition, which is very harmful to human eyesight. When the personnel are tired, there is a risk of missing the test defect.

If the actual color difference of the product is relatively small, it is easy to be missed and not intercepted. If it flows into the market, it will cause bad customer experience and complaints.

[0025] Furthermore, the sensor unit is electrically coupled to the lamp board to be tested through a test probe to collect the voltage and current of the lamp board to be tested.

[0031] Furthermore, the main controller is connected to a machine LCD display screen, and the machine LCD display screen displays data collected by the sensor unit.
[0032] Furthermore, the main controller is connected to a key input unit, and the key input unit is used for a user to input control instructions to the main controller.
[0033] Furthermore, the main controller is connected to a grating protection unit, which is set around the test fixture for placing the light board to be tested to prevent human hands or other foreign objects from entering the test machine.

This avoids safety accidents.
[0034] The specific principle of the utility model is described in detail below:
[0035] Test fixture structure: The functional interfaces of the light board are led out to the rear panel of the fixture through test probes and connecting wires. The fixture is universal (there are only three types of fixtures). When switching models, it only needs to be installed once, and the light strip can be directly placed in the fixture without frequent plugging and unplugging of wires for testing.
[0036] At the same time, the sensor unit monitors the product voltage, current test value and status in real time, and uploads the test value to the test host through the RS232 serial port. Specifically, the single-chip microcomputer module can control the cylinder to rise, fall, power on, and power off. When the product is powered on, the host computer starts to work to provide a signal light board, light up the light board, and the sensor unit collects and obtains the voltage and current test values of the light board to be tested and transmits them to the test host (PC) for subsequent use. For example, the test program that may be configured on the test host (PC) can be used to determine whether the voltage and current are normal.
[0037] Test method: When the test host sends a control instruction through the main controller to provide signals and power to the light bar, the test host sends a working signal to the photosensitive camera (signal vision system) at the same time. The photosensitive camera (signal vision system) collects the color of the light bar (red, green, blue, white) through a fixed camera and transmits it to the test host (PC) for subsequent use. For example, the test host (PC) may be configured with a test program to determine whether the color coordinates of the light bar are within the specification range to determine whether the product is normal. The entire system can detect 10 light bars at the same time, and can collect the colors of 2 to 280 LED lights at the same time, and analyze and determine. That is, after the logic control panel (SPI signal board) receives the signal from the test host, the logic control panel simultaneously outputs 10 signals to the light board to be tested, and lights up 10 groups of light bars at the same time. The camera captures the color of the light bar and analyzes the situation of each light to determine whether it is good or bad; greatly improve the test efficiency.
[0038] The utility model adopts the above technical solution. When the test host sends a control instruction through the main controller to provide signals and power to the light bar, the test host sends a working signal to the photosensitive camera (signal vision system). The photosensitive camera (signal vision system) collects the color of the light bar (red, green, blue, white) through a fixed camera and transmits it to the test host (PC) for subsequent use. At the same time, the sensor unit monitors the product voltage, current test value and status in real time, and uploads the test value to the test host through the RS232 serial port.
[0039] On the other hand, test fixtures are used to reduce the tediousness of plugging and unplugging wires in the equipment; a professional visual test system is used to avoid damage to the human eye caused by light bars, to achieve the integrity of product function testing, and to avoid defective omissions. Specifically, the main controller can control the cylinder to rise, fall, power on, and power off. When the product is powered on, the host computer starts to work to provide a signal light board, light up the light board, and the sensor unit collects and obtains the test values of the voltage and current of the light board to be tested and transmits them to the test host (PC) for subsequent use. The utility model uses a professional visual test system to avoid damage to the human eye caused by light bars, to achieve the integrity of product function testing, and to avoid defective omissions.
