[0002] SMT patching refers to the abbreviation of a series of process flows for processing on the basis of a PCB. SMT is Surface Mount Technology, which is currently the most popular technology and process in the electronic assembly industry. The surface assembly technology of electronic circuits is called surface mounting or surface mounting technology. It is a circuit assembly technology that installs leadless or short-lead surface-mounted components (abbreviated as SMC / SMD, also known as chip components in Chinese) on the surface of a printed circuit board or other substrates, and is welded and assembled by methods such as reflow soldering or dip soldering. Usually, the electronic products we use are designed from a PCB plus various capacitors, resistors and other electronic components according to the designed circuit diagram. Therefore, various electrical appliances require various different SMT patching processing technologies for processing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0019] An SMT mounter feeding device includes a base 2, a storage bin 1 and a conveying mechanism sequentially installed above the base 2. A housing 3 is installed on one side of the storage bin 1. A U-shaped feeding box 4 is slidably installed inside, and an electric push rod 5 for driving the U-shaped feeding box 4 to lift is installed at the bottom. Through holes are respectively opened on both sides. Driving holes and feeding ports are respectively opened on both sides inside the U-shaped feeding box 4. Placement partitions 6 are sequentially and equally spaced inside. A pushing mechanism is installed inside the housing 3. The conveying mechanism includes a support frame 7 installed above the base 2, a conveyor belt 8 rotatably installed on the support frame 7 through a movable shaft, and a driving component for driving the conveyor belt 8 to rotate.

[0020] Before work, the storage bin 1 can be opened, and the materials are sequentially placed on the placement partitions 6 inside the U-shaped feeding box 4. When the SMT mounter starts to work, the pushing mechanism is started, and the material on the uppermost placement partition 6 is pushed through the driving port and the through hole to reach the conveyor belt 8 through the feeding port. The material is continuously conveyed by the conveyor belt 8 to the lower part of the SMT mounter. When the material on the uppermost placement partition 6 is conveyed, the electric push rod 5 is started to drive the U-shaped feeding box 4 to rise until the material on the next layer is aligned with the pushing mechanism, so as to achieve the purpose of continuous feeding.

[0021] The pushing mechanism includes a movable roller 9 rotatably installed inside the housing 3 and a pushing rod 10 installed above the movable roller 9. One end of the rotating shaft of the movable roller 9 is connected to the output end of a servo motor I installed outside the housing, and the other end of the rotating shaft is rotatably connected to a limit seat fixedly installed inside the housing 3.

[0022] A spiral groove 11 is opened on the outer surface of the movable roller 9. A sliding column 12 fixedly installed at the bottom of the pushing rod 10 is slidably connected to the spiral groove 11. A jack is opened on one side of the housing 3 close to the storage bin 1. The pushing rod 10 penetrates through the jack and extends into the storage bin 1.

[0023] By starting the servo motor I, the movable roller 9 is driven to rotate. Under the rotation of the spiral groove 11, the sliding column 12 drives the pushing rod 10 to move, so as to complete the purpose of pushing the material.

[0024] The driving component includes a second servo motor installed outside the support frame 7. The output shaft of the second servo motor is connected to one of the movable shafts. A driving wheel and a driven wheel are respectively installed outside the two movable shafts. The driving wheel and the driven wheel are driven by a belt 14. By starting the second servo motor to drive the driving wheel to rotate, under the drive of the belt 14 and the driven wheel, the conveyor belt 8 is driven to rotate.

[0025] A cleaning brush 13 is installed inside the support frame 7 and below the conveyor belt 8, and a dust collection drawer is slidably installed below the cleaning brush 13. When the conveyor belt 8 rotates below and passes through the cleaning brush 13, its surface can be cleaned, and the impurities cleaned will fall into the dust collection drawer for collection, ensuring the cleanliness of the conveyor belt 8.
