Description

Technical Field

[0002] Ultraviolet (UV) curing equipment consists of two parts: a lamp head (lamp box) for generating UV light and a controller for controlling the lamp head. The lamp head uses an internal magnetron to generate high-power radio frequency microwave energy to power the UV lamp, a technology similar to that of a microwave oven in household appliances.

[0003] The power controller of a UV curing system contains many circuit boards, with the main control board being the most integrated and complex in design. Furthermore, its signal acquisition function involves adjusting circuit board parameters, requiring the adjustment of corresponding potentiometers to calibrate functional accuracy. Traditional manual testing and adjustment methods face many inconveniences.

[0004] 1. Large-scale production requires faster testing speeds;

[0005] 2. The cost of training skilled quality inspectors is high;

[0006] 3. Manual inspection is easily affected by subjective factors and lacks standardized procedures, which can easily affect product quality. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] See Figures 1-2 This embodiment provides an automatic testing device for the main control board of a UV curing power controller, including a main control board 1 under test and a testing board 2. The main control board 1 under test and the testing board 2 are electrically connected by multiple ribbon cables for transmitting various detection signals, including digital quantity (DI) detection, digital quantity (DO) detection, AC voltage detection, SPI bus detection, RS232 bus detection, voltage signal input detection, and voltage signal output detection.

[0026] This invention utilizes a detection board 2 and multiple ribbon cables to detect the digital input (DI), digital output (DO), AC voltage, SPI bus, RS232 bus, voltage signal input, and voltage signal output transmitted between the main control board 1 and the detection board 2. This enables automatic detection of the main control board 1 under test. Compared to traditional manual detection and debugging, this invention offers advantages such as faster detection speed, lower training difficulty for operators, and guaranteed uniformity of detection standards, thereby reducing the impact on product quality.

[0027] See Figure 2 The detection board 2 is equipped with a detection circuit, which includes a main control chip 3, a digital signal detection and output circuit, an analog voltage signal conversion and output circuit, a voltage signal acquisition circuit, and a CAN bus communication circuit.

[0028] The detection circuit enables the detection and processing of the output and input signals of the detection board 2, ensuring the normal function of the detection board 2 in detecting the main control board 1 under test.

[0029] See Figure 1 The main control board 1 under test is connected to an external 220VAC mains power supply. The main control board 1 under test has an integrated AC-DC circuit for generating a 24V DC voltage to power the detection board 2.

[0030] The main control board 1 under test is directly powered by 220VAC mains power, and the main control board 1 under test then powers the detection board 2 through an AC-DC circuit. This eliminates the need for additional wiring to power the detection board 2, reducing the number of external wires and making the invention more convenient to use.

[0031] See Figure 1 , Figure 2 The detection board 2 is externally connected to an RS485 communication circuit for establishing communication with the communication terminal.

[0032] The communication terminal is connected via an RS485 communication circuit to receive detection commands from the host computer. After the detection is completed, the detection results and fault information are sent back to the host computer, improving the speed and convenience of the detection operation.

[0033] See Figure 1 The detection circuit also includes a device indicator light control circuit, which is electrically connected to a red LED 5 and a green LED 6.

[0034] The device indicator light control circuit is used to indicate the start and stop of the detection steps through red LED 5 and green LED 6 during the detection process. At the same time, it uses red LED 5 and green LED 6 to simply indicate the detection results after the detection is completed, which improves the visualization effect of the detection steps and facilitates the rapid identification of the detection results by the staff, thereby improving the efficiency of the detection.

[0035] The operation method of this utility model is as follows:

[0036] Default operating mode: Automatic mode (e.g.) Figure 3 The value shown in row O is 0)

[0037] Setting: 0 Automatic Mode

[0038] Settings: 1 Manual Mode

[0039] Automatic mode operation (such as) Figure 3 (As shown in the first row)

[0040] Address 1: Configure automatic start / stop detection

[0041] Setting: 0 (Stop)

[0042] Settings: 1 Startup

[0043] The test results are displayed in the automatic test results window (1: test passed, 0: test failed). Test items include... Figure 4 As shown in the image. Items that pass the test turn green, and those that fail turn red (e.g., ...). Figure 5 (Lines 50, 51, and 55-66 are displayed in green, while lines 52-54 are displayed in red). If all tests pass, green LED 6 will light up; otherwise, red LED 5 will light up.

[0044] Manual detection operations (such as) Figure 3 The value shown in row O is 1)

[0045] See the operation flowchart Figure 6 .

[0046] In manual mode, to switch from one test item to the next, you must first reset, then reconfigure the test items, and then start the test. Setting new test items without resetting will not take effect.

[0047] In manual mode, there is a certain sequence switching time from manual start-up to running to the specified detection step. You need to wait a while. When running to the specified step, the green LED 6 will flash twice to indicate that the detection has started.

[0048] By looking at the current step point, you can see the detection steps that are currently running (such as...). Figure 3 (As shown in the 5th row of the middle section).

[0049] Manually test AO output channel

[0050] A fixed voltage is output on the channel corresponding to the terminal of detection board 2. A setting operation of 1 is required on the specified voltage channel. For example, in the 8th detection item, a fixed 1V voltage is output on AO1 (CONN1-1-10 channel), requiring the corresponding register to be set to 1 (e.g., ...). Figure 7 (As shown in the diagram), the other channels are similar.

[0051] See Figure 7 Each AO channel can output three different voltage values. The corresponding AutoTest-8 / 9 / 10 / 11 will display the actual voltage value detected by the corresponding test item, which is convenient for the staff to adjust the potentiometer of the main control board to ensure that the voltage value output by the AO is consistent with the actual voltage value detected by the test item, thereby ensuring that the debugging results of each tested main control board 1 are consistent.

[0052] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
