[0013] According to the aforementioned high-speed SMT placement machine with stable placement, an electromagnetic valve is provided on the outside of the air supply pipe, and the air supply pipe is located inside the suction plate, which facilitates the control of opening and closing of the air supply pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The circuit board is placed in the fixing slot. By compressing the second spring, the first contact piece and the second contact piece come into contact. This activates the second cylinder to drive the limit frame and the limit block to limit the circuit board. This can automatically fix the workpiece. The fixing method is convenient and the work efficiency is high.

[0016] 2. After the surface mount is completed, the electric telescopic rod is activated to move the unloading platform upward, making it easier to pick up the workpiece. The inclined surface of the push rod cooperates with the inclined surface of the top block, so that the top block drives the limit block to compress the first spring, releasing the limit on the circuit board, which can then fall automatically onto the unloading platform. The soft pad is used to cushion the workpiece during unloading to prevent damage. The workpiece can be automatically removed, which can save labor and improve work efficiency.

One end of each of the multiple first springs 17... Each of the limiting blocks 19 is fixedly connected, and the exterior of the multiple limiting blocks 19 is slidably connected to the interior of the multiple limiting frames 21. The interior of the fixing groove 16 is fixedly connected to the second spring 22, which is used to separate the first contact piece 23 and the second contact piece 24 after the workpiece falls, so that the second cylinder 20 automatically retracts. The lower end of the second spring 22 is fixedly connected to the pad 10, and the upper surface of the pad 10 is fixedly connected to the second contact piece 24. The inner wall of the fixing groove 16 is fixedly connected to the first contact piece 23. The first contact piece 23 and the second contact piece 24 are both located inside the second spring 22.

[0027] Both limit blocks 19 are fixedly connected to top blocks 18 on their sides, which are used to drive the limit blocks 19 to move. One end of the top block 18 extends to the outside of the patch plate 9. An electric telescopic rod 15 is fixedly connected to the bottom of the box 1, which is used to push the unloading platform 6 closer to the workpiece for easy picking. The output end of the electric telescopic rod 15 is fixedly connected to the unloading platform 6. A soft pad 7 is fixedly connected to the upper surface of the unloading platform 6. To reduce the impact of the workpiece falling, a top rod 5 is fixedly connected to the side of the unloading platform 6.

[0028] The top rod 5 has a beveled side, and the top block 18 has a beveled side that matches the bevel of the top rod 5. The top of the housing 1 is fixedly connected to the first cylinder 12, which drives the suction plate 3 to move up and down to adsorb parts. The output end of the first cylinder 12 is fixedly connected to the suction plate 3. The upper surface of the suction plate 3 is fixedly connected to the air pump 14 to provide negative pressure. The output end of the air pump 14 is fixedly connected to the air supply pipe 13. The side surface of the air supply pipe 13 is connected to the suction nozzle 4 for adsorbing parts.

[0029] Working principle: In use, the patch is first placed inside the patch slot 8, and then the circuit board is placed inside the fixing slot 16. The circuit board will squeeze the pad 10, thereby compressing the second spring 22, so that the first contact piece 23 and the second contact piece 24 come into contact. This activates the second cylinder 20 to drive the limiting frame 21 and the limiting block 19 to limit the circuit board, which can automatically fix the workpiece. The fixing method is convenient and the working efficiency is high. Then, the first cylinder 12 is activated to drive the suction plate 3 to move down. When the suction nozzle 4 contacts the patch, the air pump 14 is activated to form a negative pressure. Then the solenoid valve is closed, and the first... The cylinder 12 retracts, and then the motor 11 is started to drive the chip plate 9 to rotate, thereby placing the component on the circuit board. After the chip placement is completed, the motor 11 is used again to make the fixing slot 16 face downward, and then the electric telescopic rod 15 is started to move the unloading table 6 upward. The inclined surface of the top rod 5 cooperates with the inclined surface of the top block 18, so that the top block 18 drives the limiting block 19 to compress the first spring 17, thereby releasing the limitation on the circuit board and making it fall automatically onto the unloading table 6. The soft pad 7 is used to buffer during unloading to prevent damage to the workpiece and facilitate automatic removal of the workpiece. This can save labor and improve work efficiency.
