Description

Technical Field

[0001] This utility model relates to the technical field of monitor or television motherboard testing equipment, specifically to a cylinder pressing-down start device for a monitor or television motherboard testing machine. Background Technology

[0002] The cylinder on the motherboard testing machine for monitors or televisions (used for functional testing or program burning) lowers the lifting plate into position, but there is no communication with the test computer. Each test requires manual operation of the lowering cylinder, and after the cylinder is fully depressed, the "start" button of the test program must be manually pressed. This results in low automation and low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cylinder pressing-down starting device for a motherboard testing machine for monitors or televisions, so as to solve the efficiency bottleneck of relying on manual operation in monitor motherboard testing, and achieve high stability with low-cost hardware.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cylinder-pressed-in-position starting device for a monitor or television motherboard test bench, including a cylinder sensor, an ESP32 development board, and a test computer;

[0006] The cylinder sensor is located on the test bench and is connected to the ESP32 development board. After the cylinder sensor detects that the cylinder has been pressed down to the position, it sends a signal to the ESP32 development board.

[0007] The ESP32 development board is connected to the test computer. After receiving the cylinder position signal, the ESP32 development board sends a test start command to the test computer.

[0008] The test computer is connected to the test machine. The test machine starts the test according to the test start command. After the test is completed, the test computer sends the test results to the ESP32 development board.

[0009] Furthermore, the test computer and the test machine are connected via an RS232 serial port.

[0010] Furthermore, the ESP32 development board is equipped with indicator lights for displaying test results.

[0011] Furthermore, when the test is passed, the control indicator light on the ESP32 development board turns green, and when the test fails, the control indicator light on the ESP32 development board turns red.

[0012] This utility model adopts the above technical solution and has the following beneficial technical effects:

[0013] 1. By linking the cylinder sensor, ESP32 development board, test computer and test machine, the manual clicking of the "start button" is replaced, avoiding test delays or errors caused by operator reaction time or operational mistakes.

[0014] 2. This invention uses a general-purpose ESP32 development board, which is low-cost and easy to develop and maintain. Furthermore, it is based on a mature solution of sensor signal acquisition and serial communication, ensuring high stability and controllable risks. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] Figure 1 This is a schematic diagram of the structure of this utility model;

[0017] Figure 2 This is a flowchart illustrating the process of this utility model. Detailed Implementation

[0018] like Figure 1-2 As shown, the cylinder pressing-in start device of the motherboard test bench for monitors or televisions of this utility model includes a cylinder sensor, an ESP32 development board 2, and a test computer 3.

[0019] The cylinder sensor is located on the test bench 1 and is connected to the ESP32 development board 2. After the cylinder sensor detects that the cylinder has been pressed down to the position, it sends a signal to the ESP32 development board 2.

[0020] The ESP32 development board 2 is connected to the test computer 3 via a USB interface. After receiving the cylinder position signal, the ESP32 development board 2 sends a test start command to the test computer 3.

[0021] The test computer 3 and the test machine 1 are connected via an RS232 serial port. The test machine 1 controls the test machine 1 to start the test according to the test start command. After the test is completed, the test computer 3 sends the test results to the ESP32 development board 2.

[0022] In addition, the ESP32 development board 2 is connected to an indicator light for displaying test results. When the test is passed, the indicator light on the ESP32 development board 2 turns green; when the test fails, the indicator light turns red, facilitating quick identification of defective products on-site.

[0023] The working principle of this utility model (applied to the testing machine 1 at the left and right workstations):

[0024] 1. After the cylinder is pressed down to the position, the cylinder sensor detects that the cylinder is in position and sends a high level to the ESP32 development board 2. The ESP32 development board 2 sends {0x4F, 0x4B, 0x9A} and {0x4F, 0x4C, 0x9B} signals to the test computer 3 (which has automated testing and KEY burning program).

[0025] 2. When test computer 3 recognizes {0x4F, 0x4B, 0x9A}, test machine 1 on the left side of the program starts running; when it recognizes {0x4F, 0x4C, 0x9B}, test machine 1 on the right side of the program starts running.

[0026] 3. After the test is completed: ① If the test and burning are successful, the left side of the test computer 3 will send hexadecimal {50 4f 4bea}, and the right side will send hexadecimal {50 4f 4c eb}; ② If the test and burning are unsuccessful, the left side of the test program will send hexadecimal {50 4f 4d ec}, and the right side will send hexadecimal {50 4f 4e ed}.

[0027] 4. When the ESP receives a pass command from the left, the left light illuminates green; when it receives an NG command, the left light illuminates red. When the ESP receives a pass command from the right, the right light illuminates green; when it receives an NG (fail) command, the right light illuminates red. All indicator lights are set to off after the cylinder is depressed to avoid misjudgment.

[0028] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
