Description

Technical Field

[0001] This utility model relates to the field of IC chip programming technology, specifically to a motherboard programming power switch fixture. Background Technology

[0002] The operator at the motherboard manual programming station used a manual switch fixture to program IC chips. There was a risk that the programming winding was removed before the power switch was turned off after programming, which caused the display product to have no picture. Later, the machine needed to be disassembled for repair, which increased the company's labor costs and time losses. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a motherboard programming power switch fixture.

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

[0005] A motherboard programming power switch fixture includes a fixture housing, wherein the fixture housing contains an RS232 control relay module, a relay, and a power adapter.

[0006] The power adapter is electrically connected to the RS232 control relay module, and the power adapter supplies power to the RS232 control relay module, so that the RS232 control relay module is in standby mode.

[0007] The output terminal of the relay is electrically connected to the power control board, which is used to supply power to the burner.

[0008] The RS232 control relay module is connected to the PC host for communication. The PC host sends commands to the RS232 control relay module through the serial port and controls the relay to turn on and off, thereby controlling the power control board to turn on and off.

[0009] Furthermore, the relay is a DC12V relay.

[0010] Furthermore, the power adapter and the relay are powered by two AC220V voltages respectively.

[0011] The present invention adopts the above technical solution and has the following beneficial effects: After the motherboard program is burned, the power can be automatically controlled to turn off, and the operator does not need to manually switch the power on and off, reducing manual work, greatly improving efficiency and product quality assurance, and saving stationing time and labor costs. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0013] Figure 1This is a schematic diagram of the circuit principle of this utility model. Detailed Implementation

[0014] like Figure 1 As shown, the motherboard programming power switch fixture of this utility model includes a fixture box, and the fixture box is provided with an RS232 control relay module 1, a relay 2 and a power adapter 3; the relay 2 is a DC12V relay.

[0015] Power adapter 3 is electrically connected to RS232 control relay module 1. Power adapter 3 supplies power to RS232 control relay module 1 (providing DC12V voltage), so that RS232 control relay module 1 is in standby mode.

[0016] The output terminal of relay 2 is electrically connected to power control board 4, which is used to supply power to burner 5.

[0017] The RS232 control relay module 1 is connected to the PC host 6, which is also connected to the burner 5. The PC host 6 provides the burner 5 with burning software. The PC host 6 sends commands to the RS232 control relay module 1 via the serial port and controls the on / off state of the relay 2, thereby controlling the power control board 4 to turn on and off.

[0018] The power adapter 3 and the relay 2 are powered by two AC220V voltages respectively.

[0019] Among them, RS232 control relay module 1, relay 2 and power adapter 3 are all products that can be purchased on the existing market.

[0020] Before the programming begins, the PC host 6 sends a command via serial port to the RS232 control relay module 1 and controls the relay 2 to turn on, power control board 4 turns on, and the programming machine 5 begins programming the motherboard. After the motherboard programming is completed, the PC host 6 receives feedback from the programming software and then sends a command via serial port to the RS232 control relay module 1 and controls the relay 2 to turn off, cutting off the power control board 4. This achieves automated switching of the programming power, eliminating the need for operators to manually switch the power on and off, reducing manual labor, greatly improving efficiency and product quality assurance, and saving time and labor costs.

[0021] 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.
