[0023] Please see Figure 1-4The present invention provides a technical solution: an automatic feeding circuit board mounting device, including a feeding structure 1, a mounting base 2 and a conveyor belt 3. The mounting base 2 is provided at the four corners of the side end of the conveyor belt 3, and the feeding structure 1 is fixedly provided at the center side end of the conveyor belt 3.

[0024] Conveyor belt 3 is used for transporting circuit boards;

[0025] Mounting bracket 2 is used for fixed installation of the pick and place machine;

[0026] The feeding structure 1 is used for automated feeding. The guide seat 4 inside the feeding structure 1 is connected to the guide belt 7, and the control motor 5 controls the rotation of the guide belt 7, so that the chip is transferred and guided on the guide belt 7. The swing rod 13 and the barrier frame 14 can limit the chip to prevent the chip from falling. The mounting seat 2 is installed, which is used for the installation of the pick and place machine. The conveyor belt 3 can transfer the circuit board. The setting of the feeding structure 1 facilitates the feeding work, so that the chip reaches the designated position and is then processed by the pick and place machine on the mounting seat 2, which helps to automate the pick and place process.

[0027] The feeding structure 1 includes a mounting plate 6, on which a control motor 5 is mounted. The control motor 5 controls the rotation of the guide belt 7. A guide seat 4 is fixedly provided on the side end of the mounting plate 6, and the guide seat 4 is connected to the guide belt 7.

[0028] A protection board 8 is fixedly connected to the mounting plate 6, which provides top protection for the chip.

[0029] A positioning detector 9 is fixedly installed on the upper side of the mounting plate 6 for detecting the chip position.

[0030] A fixed plate 10 is fixedly connected to the side of the mounting plate 6. A stepper motor 12 is mounted on the fixed plate 10. The stepper motor 12 controls the rotation of the swing arm 13, and a barrier frame 14 is fixedly connected to the swing arm 13. By installing the feeding structure 1, the guide seat 4 in the feeding structure 1 is used for chip transfer. The guide seat 4 is connected to the guide belt 7. The control motor 5 controls the rotation of the guide belt 7, so that the chip is transferred on the guide belt 7 and reaches the lower end of the position detector 9 for sensing and detection. At this time, the stepper motor 12 controls the swing arm 13 to rotate, changing the position of the barrier frame 14, so that the barrier frame 14 blocks the chip. Then the pick-and-place machine can adsorb and install the chip.

[0031] The mounting plate 6 is also fixedly connected to a limit sleeve 11, which is sleeved with the swing rod 13.

[0032] Working principle: When needed, a chip mounter is installed on mounting base 2. The circuit board is transported on conveyor belt 3. When it reaches the position of mounting base 2, the feeding structure 1 loads the chip. The guide seat 4 is used for chip transport. After reaching the guide belt 7, the mounting plate 6 controls the rotation of the guide belt 7 to change the chip position, so that the chip reaches the lower position of the positioning detector 9. The protection plate 8 is set to limit the chip's upper position. The positioning detector 9 detects the chip position. At this time, the stepper motor 12 controls the swing arm 13 to rotate, so that the barrier frame 14 is in position. Figure 4 In this state, the barrier 14 is used to block the chip. The pick-and-place machine reaches the top of the chip and performs chip adsorption and gripping. Then, the stepper motor 12 controls the swing arm 13 to rotate, so that the barrier 14 is released from the chip limit. The pick-and-place machine places the chip into the circuit board on the conveyor belt 3 to complete the work.
