Description

Technical Field

[0001] This invention relates to the field of electronic components technology, specifically to a feeding and discharging device for electronic components and its usage method. Background Technology

[0002] Electronic components are the components of electronic parts and small machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in the electrical, radio, and instrument industries, and are a general term for electronic devices such as capacitors, transistors, hairsprings, and clockwork. Among them, resistors include surface mount resistors.

[0003] Chinese Patent Publication No. CN 210854190 U discloses an automatic feeding and discharging device, including a vibrating plate and a conveying mechanism connected to the vibrating plate. The other end of the conveying mechanism is provided with a detachable pushing mechanism and a mold mechanism on both sides. The top surfaces of the pushing mechanism, the conveying mechanism and the mold mechanism are located on the same plane. Compared with the prior art.

[0004] The feeding and discharging device in the aforementioned patent involves material being vibrated out of the oscillating plate and entering the conveyor track. The conveyor track continues to move horizontally to feed the material, while the pusher pins repeatedly push the material to fill the material placement slot 9a sequentially. However, when used on surface mount resistors, it is necessary to ensure the orientation of the surface mount resistors during processing to avoid positional errors. This requires extremely high accuracy in orientation and position, making the device unsuitable if the positional accuracy issue cannot be resolved. To address this, we provide a feeding and discharging device for electronic components. This device monitors the angle and orientation of the surface mount resistors, uses a negative pressure suction head to pick them up, rotates a rotary joint to adjust the angle, and coordinates with multiple cylinders to adjust the position, ensuring feeding accuracy and effectively overcoming the aforementioned problems. Summary of the Invention

[0005] Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a small motor packaging device. The device uses clamping arms to hold and move the small motors conveyed by the motor conveyor. A packaging box conveyor on one side conveys the packaging boxes one by one. The clamping arms place the motors into the packaging boxes on the packaging box conveyor, thus completing the protection and transportation. This device is more convenient to use and solves the technical problems mentioned in the background.

[0006] Technical solution To achieve the objectives of this invention, the technical solution adopted is as follows: A feeding and unloading device for electronic components includes a vibrating feeder; a feeding conveyor belt is provided on one side of the vibrating feeder, and a negative pressure suction head is provided above the feeding conveyor belt and is connected to a rotary joint; the rotary joint is installed on a longitudinal slide, and a negative pressure pipe is connected to the rotary joint, the other end of which is connected to a negative pressure machine; the longitudinal slide is slidably connected to a longitudinal guide rail, the longitudinal guide rail is fixed to a lifting slide by bolts, and the lifting slide is slidably connected to the lifting guide rail; the lifting guide rail is fixed to a transverse slide by bolts. The outer side of the feeding conveyor belt is wrapped with a rubber ring, and multiple mounting grooves are evenly opened inside the rubber ring. A lever support is fixedly installed at the center of the mounting groove, and a lever is movably installed at the top of the lever support through a rotating shaft. The two ends of the lever are respectively connected to a stop block and an adjusting block through a rotating shaft. A material trough is opened on one side of the stop block.

[0007] As a further technical solution of the present invention, the feeding conveyor belt is installed in the groove of the operating table, and a material transfer plate is attached above the feeding conveyor belt. The material transfer plate is installed on the discharge port of the vibrating feeder. The vibrating feeder is fixed to the vibrating feeder bracket by bolts.

[0008] As a further technical solution of the present invention, a toothed ring is connected to the outer side of the rotary joint, the toothed ring meshes with a gear, and the gear is connected to the drive shaft of the drive motor; the drive motor is fixed to the longitudinal slide by bolts.

[0009] As a further technical solution of the present invention, the transverse slide block is slidably connected to the transverse slide rail frame, which is fixed to the operating table by bolts, and the transverse slide block is also connected to the transverse lead screw by threads; the transverse lead screw is connected to the bearing mounted on the transverse slide rail frame, and one end of the transverse lead screw is connected to the drive shaft of the drive motor, which is fixed to the transverse slide rail frame by bolts.

[0011] As a further technical solution of the present invention, a monitor is provided above the feeding conveyor belt. The monitor is fixed to the lifting frame by bolts, and the lifting frame is fixed to the operating table by bolts.

[0012] A method for using an electronic component feeding and discharging device includes the following steps: Step 1: The vibrating feeder feeds the patches one by one along the feed plate onto the feed conveyor belt. After the patches reach the feed conveyor belt, they fall into the trough. At this time, the patches press against the adjusting block. Through the action of the lever support and the lever, the stop block at the other end of the lever rises, thereby blocking the patches behind and completing the orderly feeding process. At the same time, the monitor 5 above monitors the feeding direction of the patches. Step 2: When the orientation of the patches is not uniform, the drive shaft of the drive motor rotates, which will drive the connected transverse lead screw to rotate. Under the action of the transverse slide block and the transverse lead screw being threadedly connected and slidingly connected to the transverse slide rail frame, the transverse slide block moves along the transverse slide rail frame, indirectly adjusting the position of the negative pressure suction head. Step 3: The push rod of the lifting cylinder pushes the lifting slide to move along the lifting guide rail, which makes it easier for the negative pressure suction head to move downward to suck up and release material. The push rod of the longitudinal cylinder pushes the longitudinal slide to move along the longitudinal guide rail, which makes it easier for the negative pressure suction head to pick up the center position of the patch and ensure the stability of the material suction. Step four: The negative pressure pump is connected to the rotary joint through the negative pressure pipe, and the rotary joint is connected to the negative pressure suction head to pick up the patch that is not facing correctly; the drive motor drive shaft drives the connected gear to rotate, thereby driving the meshing gear ring to rotate, and the rotary joint and negative pressure suction head rotate accordingly, thereby achieving the purpose of rotating and adjusting the orientation of the patch, which can effectively ensure the accuracy of feeding.

[0013] Beneficial effects: In this invention, a vibrating feeder feeds the chip resistors via a conveyor belt. The vibrating feeder feeds the chip resistors one by one along the conveyor plate onto the conveyor belt. After the chip resistors reach the conveyor belt, they fall into the trough. At this time, the chip resistors press against the adjusting block. Through the action of the lever support and the lever, the stop block at the other end of the lever rises, thereby blocking the chip resistors behind and completing the orderly feeding process. When the chip resistor is not facing correctly, the lifting slide moves along the lifting guide rail to provide the negative pressure suction head with the action of picking up and putting down the chip resistors. The longitudinal slide moves along the longitudinal guide rail to adjust the position of the negative pressure suction head on the conveyor belt. The negative pressure pump is connected to the rotary joint through the negative pressure pipe, and the rotary joint is connected to the negative pressure suction head to pick up the chip resistors. The rotary joint rotates to adjust the chip resistor angle and then lowers it, thereby ensuring the accuracy of chip resistor feeding. In this invention, the drive shaft of the drive motor drives the connected gear to rotate, thereby driving the meshing gear ring to rotate, providing power for the rotation of the rotary joint, and the rotation of the rotary joint will not affect the negative pressure pipe. In this invention, the drive shaft of the drive motor drives the connected transverse lead screw to rotate. Under the action of the transverse slide block being threadedly connected to the transverse lead screw and slidably connected to the transverse slide rail, the transverse slide block moves along the transverse slide rail, thereby providing power for the negative pressure suction head to move above the corresponding patch.

[0021] By adopting the above technical solution, the drive shaft of the drive motor 23 drives the connected gear 22 to rotate, thereby driving the meshing gear ring 21 to rotate, providing power for the rotation of the rotary joint 19. The rotation of the rotary joint 19 will not affect the negative pressure pipe 18.

Under the action of the transverse slide block 11 being threadedly connected to the transverse lead screw 9 and slidably connected to the transverse slide rail frame 8, the transverse slide block 11 moves along the transverse slide rail frame 8, thereby providing power for the negative pressure suction head 20 to move above the corresponding patch.

[0028] A method for using an electronic component feeding and discharging device includes the following steps: Step 1: The vibrating feeder 2 vibrates to feed the patches, so that the patches will enter the feeding conveyor belt 7 one by one along the feed plate 3.

Through the action of the lever support 72 and the lever 73, the stop block 74 at the other end of the lever 73 rises, thereby blocking the patches behind, completing the orderly feeding process. At the same time, the monitor 5 above monitors the feeding direction of the patches. Step 2: When the orientation of the patch is not uniform, the drive shaft of the drive motor 10 rotates, which will drive the connected transverse lead screw 9 to rotate. Under the action of the transverse slide block 11 being threadedly connected to the transverse lead screw 9 and slidingly connected to the transverse slide rail frame 8, the transverse slide block 11 moves along the transverse slide rail frame 8, indirectly adjusting the position of the negative pressure suction head 20. Step 3: The push rod of the lifting cylinder 14 pushes the lifting slide 13 to move along the lifting guide rail 12, so that the negative pressure suction head 20 can move downward to suck up and release material. The push rod of the longitudinal cylinder 16 pushes the longitudinal slide 17 to move along the longitudinal guide rail 15, so that the negative pressure suction head 20 can adsorb the center position of the patch and ensure the stability of the suction. Step four: The negative pressure pump is connected to the rotary joint 19 through the negative pressure pipe 18, and the rotary joint 19 is connected to the negative pressure suction head 20 to pick up the patch that is not facing correctly; the drive motor 23 drives the drive shaft to rotate the connected gear 22, thereby driving the meshing gear ring 21 to rotate, and the rotary joint 19 and the negative pressure suction head 20 rotate accordingly, thereby achieving the purpose of adjusting the orientation of the patch by rotation, which can effectively ensure the accuracy of feeding.
