In the above manner, multiple sets of rail frames 350 are sequentially spliced ​​into one piece;

[0098] There are two ways to use it:

[0099] The first method is: inserting the first placement rack 340 holding the circuit board from the driving-in position of the spliced ​​rail frame 350, and then processing the upper side of the circuit board on the placement rack 340 at the driving-in position, after processing, sliding the first placement rack 340 inwards, sliding the first placement rack 340 away from the driving-in position, and then inserting the second placement rack 340 holding the circuit board from the driving-in position of the spliced ​​rail frame 350, and then processing the upper side of the circuit board on the placement rack 340 at the driving-in position, after processing, sliding the second placement rack 340 inwards, sliding the second placement rack 340 away from the driving-in position, and then inserting the third placement rack 340 holding the circuit board from the driving-in position of the spliced ​​rail frame 350, and so on, successively inserting each placement rack 340 holding the circuit board from the driving-in position of the spliced ​​rail frame 350, and After the processing of the driving-in position, the rack 340 is turned away from the position until the last rack 340 is inserted from the driving-in position of the spliced ​​rail frame 350. After the processing of the driving-in position, the flip rack 300 is immediately driven to rotate as a whole through the action of the first touch screen 311, so that a group of racks 340 are flipped at one time. After flipping, the other side of the circuit board on the rack 340 at the driving-in position is processed first. After processing, the rack 340 at the driving-in position is extracted from the driving-in position, and then the second rack 340 is slid to the driving-in position, and then the other side of the circuit board on the rack 340 at the driving-in position is processed. After processing, the rack 340 at the driving-in position is extracted from the driving-in position, and the other side of the circuit board on each rack 340 is processed in sequence. After processing, the rack 340 is extracted from the driving-in position, and the other side of the circuit board on each rack 340 is processed. After processing, the rack 340 is extracted from the driving-in position, and the operation of double-sided processing of a group of circuit boards is completed.

[0100] Alternatively, each placement rack 340 is first inserted into the entry position of the spliced ​​rail frame 350, and then the upper side of the circuit board on the entry position placement rack 340 is processed. After processing, the entry position placement rack 340 is immediately driven to rotate independently through the action of the No. 3 driving motor 3422 of the entry position placement rack 340, and the entry position placement rack 340 is turned over. After turning over, the other upper side of the circuit board on the entry position placement rack 340 is processed to complete a set of circuit board double-sided processing operations. After processing, the circuit boards in each placement rack 340 are taken out one by one, and then each circuit board to be processed is placed in each placement rack 340 in turn, and then the entry position placement rack 340 is first processed. The circuit board on the placement rack 340 at the driving position is processed on the upper side. After the processing, the driving-in position placement rack 340 is immediately driven to rotate independently by the action of the No. 3 driving motor 3422 of the driving-in position placement rack 340, and the driving-in position placement rack 340 is turned over. After the turning over, the other upper side of the circuit board on the driving-in position placement rack 340 is processed. After the processing, the driving-in position placement rack 340 is withdrawn, and the second placement rack 340 is moved to the driving-in position, and the two sides of the circuit board on the second placement rack 340 are processed. After the processing, the driving-in position placement rack 340 is withdrawn from the driving-in position, and each placement rack 340 is withdrawn in turn, and then the cycle is repeated;

[0101] The first method is: inserting the three placing racks 340 from the driving-in position of the spliced ​​rail frame 350, so that the first placing rack 340 is placed in the middle position of the spliced ​​rail frame 350, and then clamping the circuit board on the three placing racks 340 in sequence, first processing the upper side of the circuit board on the placing rack 340 at the middle position, after processing, the placing rack 340 at the middle position is driven to rotate independently by the action of the No. 3 driving motor 3422 of the placing rack 340 at the middle position, and the placing rack 340 at the middle position is turned over, and then the other upper side of the circuit board on the placing rack 340 at the middle position is processed after turning over, and after both sides are processed, the placing rack 340 is moved right, and the second placing rack 340 is moved to the middle position, and then the circuit board on the second placing rack 340 is processed on both sides, and then the circuit board on the third placing rack 340 is processed on both sides according to the above method, and a set of circuit board double-sided processing operations are completed;

[0102] Alternatively, three racks 340 are inserted from the driving position of the spliced ​​rail frame 350, so that the first rack 340 is placed in the middle position of the spliced ​​rail frame 350, and then the circuit board is clamped on the three racks 340 in sequence, and the upper side of the circuit board on the rack 340 in the middle position is processed first. After the processing, the rack 340 is moved to the right, and the second rack 340 is moved to the middle position, and the upper side of the circuit board on the second rack 340 is processed, and then the circuit board on the third rack 340 is processed in the above manner. After the upper sides of the circuit boards on a set of racks 340 are processed, the flip rack 300 is driven to rotate as a whole through the function of the first touch screen 311, so that a set of racks 340 are flipped at one time, and then the other side of the circuit board on the rack 340 in the middle position is processed. After processing, the rack 340 is moved to the left, and the second rack 340 is moved to the middle position. Then, according to the above method, the upper side of the circuit board on the third rack 340 is processed, and the double-sided processing operation of a set of circuit boards is completed;

[0103] To store a set of rail racks 350:

[0104] The rail frames 350 are stacked vertically one by one, so that the top seat 352 of the lower rail frame 350 is tightly inserted into the inner groove 353 of the upper rail frame 350. After two rail frames 350 are connected and limited by the insertion rod 354, a group of rail frames 350 can be stacked. Example
