It can operate on multiple circuit boards at the same time, greatly improving the production efficiency. When working, the device will be connected to the circuit board through the interface, and then the pre-prepared program data will be accurately transmitted to the target chip. This process requires precise signal control and data transmission protocol support to ensure that the program is written correctly. It usually has multiple transmission interfaces, and the device will monitor the writing process. If an error occurs, such as data transmission interruption, write address error, etc., an error prompt will be given in time. This device is widely used in the field of electronic product manufacturing.

[0030] Working principle: In the first step, after the staff places the circuit board on the placement platform 13, the driving motor 17 is started. The driving motor 17 drives the transmission rod 29 to rotate. Since the synchronous sprockets 38 on the two transmission rods 29 are connected by the synchronous chain 27, the two transmission rods 29 will drive the rotating bevel gear 2 32 to rotate synchronously. When the two rotating bevel gears 2 32 rotate, they will drive the meshing bevel gear 2 28, the rotating threaded rod 2 31 and the transmission column 34 to rotate. The two lifting plates 40 will drive the pressing plates 30 to descend with the rotation of the rotating threaded rod 2 31 until the two pressing plates 30 clamp the two ends of the circuit board. At this time, the circuit board will not be offset during burning, avoiding the problem that the displacement of the circuit board may cause a short circuit between the write head and the chip pins, thereby improving the success rate of writing the program.

[0031] In the second step, when the two lifting plates 40 move vertically, the limit blocks 39 at both ends of the lifting plates 40 will also move with the movement of the lifting plates 40, and the limit blocks 39 are all located inside the limit grooves 41, thereby ensuring that the lifting plates 40 can be lifted and lowered smoothly, so that the pressing plate 30 can accurately fix the circuit board and ensure smooth burning.

[0032] In the third step, the limit ring 36 provides stable support for the drive motor 17 when it starts. When the drive motor 17 starts, vibration may occur due to the power output, and the limit ring 36 is connected to the drive motor 17. Therefore, the limit ring 36 can absorb part of the vibration energy when the motor starts, reduce the impact on surrounding components, and extend the service life of the equipment.

[0033] The fourth step, when the transmission rod 29 at the left end rotates, the rotating bevel gear 37 will also rotate, and the rotating bevel gear 37 drives the meshing bevel gear 20 and the connecting column 21 to rotate. At this time, the rotating threaded rod 18 also rotates with the connecting column 21. When the rotating threaded rod 18 rotates, the U-shaped block 25 will move laterally. The staff controls the cleaning rubber brush 23 to move in a circle with the damping shaft 26 as the center, and moves the cleaning rubber brush 23 to the surface of the circuit board. At this time, when the U-shaped block 25 moves laterally, the cleaning rubber brush 23 will sweep the surface of the circuit board, effectively cleaning the surface of the circuit board, removing impurities such as dust and debris, and effectively preventing impurities from affecting the electrical performance of the circuit board, ensuring the stability of burning and subsequent use.

[0034] In the fifth step, when the staff moves the cleaning rubber brush 23, the cleaning rubber brush 23 can only rotate with the damping shaft 26 as the center, and the damping shaft 26 is made of damping material, which can provide appropriate resistance for the cleaning rubber brush 23 to avoid accidental scratching of the circuit board due to excessive rotation. At the same time, it can maintain a stable position without external force, which is conducive to precise cleaning operations.
