There are two support columns 12, the PCBA board is rectangular, and the stabilizing column 16 and the two support columns 12 abut against three corners of the PCBA board.

[0040] A terminating column 17 is further vertically arranged at the bottom of the support plate 8. During programming, the downward pressing rod 6 abuts against the top of the support plate 8, the terminating column 17 abuts against the top of the support bottom plate 1, and the pressing plate block 7 presses the plug-in component on the PCBA board to be in contact with the programming probe 15.

[0041] The pressing plate body 5 is movably sleeved on all the guide columns 2, which improves the movement stability of the pressing plate body 5.

[0042] The elastic member 10 is movably sleeved on the outer wall of the support rod 9, which can preferably prevent the elastic member 10 (i.e., the spring) from deforming.

[0043] A support base plate 1 is provided with a support frame 18, and an L-shaped protective member 19 is hingedly arranged on the support frame 18. The protective member 19 includes a protective arm 19a and an anti-rotation arm 19b perpendicular to the protective arm 19a. The length of the protective arm 19a is greater than the length of the anti-rotation arm 19b. A stop block 20 is further arranged on the support base plate 1. The stop block 20 is located below the protective member 19. The top of the stop block 20 includes a first support inclined surface 21, a relief groove 22 and a second support inclined surface 23 arranged in sequence. The protective member 19 includes a first state and a second state;

[0044] When the protective member 19 is in the first state, the tops of both the protective arm 19a and the anti-rotation arm 19b are lower than the support plate 8, and the lower side of the protective arm 19a is attached to the second support inclined surface 23. The free ends of the protective arm 19a and the anti-rotation arm 19b are located on both sides of the support frame 18;

[0045] When the protective member 19 is in the second state, the top of the protective arm 19a abuts against the top of the support plate 8, and the top of the elastic member 10 is in a separated state from the support plate 8. The lower side of the anti-rotation arm 19b is attached to the first support inclined surface 21. The free ends of the protective arm 19a and the anti-rotation arm 19b are located on the same side of the support frame 18.

[0046] A drag reduction column 24 is rotatably arranged at the free end of the anti-rotation arm 19b, and the drag reduction column 24 is movably abutted against the bottom of the support plate 8.

[0047] An operating rod 25 is horizontally arranged on the outer side of the protective arm 19a. A rotating cylinder 26 is rotatably sleeved on the outer wall of the operating rod 25. The projection of the free end of the rotating cylinder 26 in the vertical direction is located outside the projection of the support plate 8 in the vertical direction.

[0048] A connecting column 27 is arranged on the outer side of the support frame 18. An auxiliary spring 28 in a continuously extended state is arranged between the free end of the connecting column 27 and the operating rod 25.

[0049] There are two support frames 18, and the two support frames 18 are located below both sides of the support plate 8.

[0050] A programming device for a PCBA board provided by the utility model. When programming the PCBA board, first, the worker manually places the PCBA board flat on several support columns 12, and makes the pre-opened holes on the PCBA board sleeved on the limit protrusions 13. At this time, the bottom of the PCBA board is supported by the support columns 12, and the horizontal direction is limited by the limit protrusions 13. Therefore, the PCBA board can stably maintain its position. Then, the driving cylinder 4 (preferably a cylinder) drives the pressing plate body 5 to descend. During the descending process, first, the lower pressing rod 6 touches the top of the support plate 8 and drives the support plate 8 to descend. At the same time, the pressing plate block 7 fits on the top of the PCBA board, or there is a very small gap between the pressing plate block 7 and the PCBA board; after descending a certain distance, the connectors on the PCBA board are in contact with or connected to the programming probes 15; at this time, stop driving the pressing plate body 5 downward (if the lower pressing rod 6 acts on the support plate 8 and the pressing plate block 7 acts on the PCBA board simultaneously) or move downward a very small distance (if the lower pressing rod 6 acts on the support plate 8 and the pressing plate block 7 acts on the PCBA board successively), and then the PCBA board can be programmed through the programming probes 15. After programming is completed, the driving cylinder 4 raises the pressing plate body 5, and at the same time, the elastic member 10 drives the support plate 8 to rise, so that the PCBA board is separated from the programming probes 15, which is convenient for the worker to remove the PCBA board and place a new PCBA board. Since the worker only needs to manually place the PCBA board throughout the process (the driving cylinder 4 is preferably automatically started at a fixed time and can also be manually controlled according to the actual situation) to complete the programming, the operation effect is better, and the production efficiency is high.

[0051] In this embodiment, it is preferably that when the lower pressing rod 6 just acts on the top of the support plate 8, there is still a certain gap between the pressing plate block 7 and the PCBA board at this time. In this way, the acting force of the support plate 8 descending is applied through the lower pressing rod 6, that is, the PCBA board does not need to bear pressure, which plays a protective role for it.

[0052] During the descending process of the lower pressing rod 6, after the connectors on the PCBA board are in contact with the programming probes 15, the PCBA board is supported by the programming probes 15; then the pressing plate body 5 continues to descend a small distance, and the pressing plate block 7 (preferably having a certain elasticity or flexibility) presses the PCBA board against the programming probes 15; at the same time, the termination column 17 touches the support bottom plate 1 at this time, so that the termination column 17 prevents the further descent of the support plate 8, that is, prevents the pressing plate block 7 from applying too much pressure to the PCBA board, and the protection effect on the PCBA is better.

[0053] The PCBA is rectangular, and holes (self-provided) are opened at its four corners. When placing it, only need to sleeve two holes at the diagonal corners onto the limit protrusions 13, and then place it downward, and make the bottom of the PCBA board touch the support columns 12 and the stabilizing columns 16, then the position of the PCBA board can be ensured to be stable, which ensures the efficiency from the side.

[0054] During the programming process, the elastic member 10 is used to reset the support plate 8, and the support rod 9 is used to keep the support plate 8 in a horizontal state. At the same time, during the use of the device, at this time, both the protective arm 19a and the anti-rotation arm 19b are lower than the support plate 8 (even when the support plate 8 moves to the lowest height), so the programming can proceed normally. At the same time, the protective arm 19a has a relatively large mass, so the lower side thereof fits on the second support inclined plane 23. At the same time, with the downward inclination pulling force of the auxiliary spring 28, the protective member 19 can be kept at a stable angle.

[0055] When the programming device is shut down and not in use (such as at night, on weekends, etc.), the operating rod 25 is rotated upward by the rotating cylinder 26, and the protective arm 19a raises the support plate 8 through the resistance reducing column 24. After the protective arm 19a rotates to the highest height and then rotates a small angle continuously, the lower side of the anti-rotation arm 19b abuts against the first support inclined plane 21. In this way, the support plate 8 can be supported by the resistance reducing column 24, and the support plate 8 at this time is higher than the elastic member 10. In this standby state, the elastic member 10 can be free from pressure, so that it can have a longer service life. At the same time, in this state, the auxiliary spring 28 can also exert a pulling force on the protective member 19, and the protective member 19 can better maintain its angle.

[0056] Both bottom sides of the support plate 8 can be supported by the anti-rotation arm 19b, improving its position stability. At the same time, when operating the protective member 19, since the outer end of the rotating cylinder 26 is located outside the support plate 8, the operation is not affected by the support plate 8, and the operation convenience is high.

[0057] Moreover, in this embodiment, the top of the support rod 9 is threadedly connected to the bottom of the support plate 8 (the top of the support rod 9 has an external thread, and a threaded hole is opened at the bottom of the support plate 8). After the elastic member 10 has been used for a relatively long time, it is necessary to replace the elastic member 10. At this time, only the bottom of the support rod 9 needs to be rotated below the support bottom plate 1, and the support rod 9 is separated from the bottom of the support plate 8 and moved downward. Then, the elastic member 10 can be directly taken out and replaced with a new one, so as to ensure that the support plate 8 can be reset in time.

[0058] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention according to the above disclosure shall fall within the protection scope of the claims.
