Description

Technical Field

[0001] The utility model relates to the field of chip processing, in particular to an automatic feeding mechanism for a resettable fuse chip. Background Art

[0002] A resettable fuse is a device that protects electronic circuits from damage due to overcurrent, overload, overheating or short circuit. There are two types of resettable fuses, traditional radial lead and SMD chip packages. The resettable fuse has a positive temperature coefficient, which means that the resistance will increase when the temperature rises. When the temperature rises due to overcurrent or similar fault conditions, the resistance in the fuse will increase, thereby reducing the current. The resettable fuse chip needs to be transported using a loading mechanism to facilitate subsequent processing of the chip.

[0003] After searching, Chinese patent announcement number: CN219044685U discloses a chip base feeding mechanism, which starts the servo motor at one end of the fixed beam, rotates the screw, and makes the movable block drive the movable beam to move, thereby achieving the purpose of adjusting the position of the suction nozzle, so that the suction nozzle is above the chip base so that the suction nozzle can suck the chip base and improve the feeding efficiency.

[0004] In the above technical solution, a motor cooperates with a screw and then uses a suction nozzle to adsorb the chip, thereby completing the chip loading. However, the suction nozzle may damage the components on the surface of the chip when adsorbing the chip. At the same time, the chip lacks a pre-cleaning function during loading. The dust remaining on the surface of the chip will increase the subsequent processing steps, thereby reducing the chip loading effect. For this reason, an automatic loading mechanism for a self-resetting fuse chip is proposed to solve the above problems. Summary of the invention

[0032] Reference Figure 1-Figure 3 The material transport component includes a support column 6, which is connected to a rotating shaft 9 through a transmission belt. A motor 8 is fixedly connected to the top of the rotating shaft 9. Through the programming of the PLC controller, the motor 8 is preset in advance to drive the rotating shaft 9 to rotate forward and reverse. When rotating forward, the rotating shaft 9 causes the support column 6 to rotate toward the left side of the base 1 through the transmission belt. The outer wall of the motor 8 is fixedly connected to a mounting frame 7. The loading component includes a fixed frame 10. A conveyor belt 11 is arranged on the surface of the fixed frame 10. The conveyor belt 11 passes through two The conveyor rollers are driven by a group of conveyor rollers, which are operated by a driving motor. A U-shaped plate 12 is fixedly connected to the top of the fixed frame 10, an air pump 13 is fixedly connected to the top of the U-shaped plate 12, a three-way pipe 14 is fixedly connected to the input end of the air pump 13, and the two ends of the three-way pipe 14 away from the air pump 13 are located between the U-shaped plate 12 and the conveyor belt 11. A shunt pipe 15 is fixedly connected to the inner wall of the three-way pipe 14. The setting of the shunt pipe 15 can evenly shunt the gas in the three-way pipe 14. The feeding assembly includes a support plate 16, the surface of the support plate 16 is fixedly connected with an electric push rod 17, and the output end of the electric push rod 17 is fixedly connected with a release plate 18. The release plate 18 can cover or release the opening of the storage shell 2 through the operation of the electric push rod 17. The upper surface of the base 1 is fixedly connected with an inclined plate 19, and the inclined plate 19 drives the chip to slide to the bottom of the robot arm body 5 under the influence of gravity. The top of the support column 6 is fixedly connected to the bottom of the bracket 3, and the bottom end of the support column 6 is rotatably connected to the upper surface of the base 1. The lower surface of the mounting frame 7 is fixedly connected to the upper surface of the base 1. The fixed frame 10 is fixedly connected to the outer wall of the base 1 through a support rod. The three-way pipe 14 and the shunt pipe 15 are connected. The three-way pipe 14 and the shunt pipe 15 extract dust from the surface of the chip, and the output end of the air pump 13 is connected to the external pipeline to discharge dust. The side wall of the support plate 16 is fixedly connected to the side of the storage shell 2 close to the bracket 3, and the end of the inclined plate 19 close to the storage shell 2 is higher than the end of the inclined plate 19 away from the storage shell 2.

[0033] Reference Figure 4A baffle 20 is fixedly connected to the upper surface of the base 1. The baffle 20 is made of rubber material and has a certain hardness. It will not cause collision damage to the chip when it slides. A T-block 21 is fixedly connected to the side wall of the baffle 20. The side of the T-block 21 away from the baffle 20 is gradually inclined downward. The inclined surface can provide a certain buffer for the chip when it falls. An L-block 22 is set on the top of the T-block 21. The setting of the L-block 22 prevents the chip from bouncing upward and provides a limit for the chip before grabbing.

[0034] Working principle: Multiple groups of chips are stored inside the storage shell 2. When the chips need to be loaded in sequence for subsequent processing, the electric push rod 17 is first started. The electric push rod 17 intermittently drives the release plate 18 to rise and fall. When the release plate 18 rises, it unfolds the opening of the storage shell 2. After the opening is released, the chips can fall individually from the inclined plate 19. The blocking bar 20 provides a blocking function for the chips, so that the chips remain in the lower position of the robot arm body 5. At this time, the cylinder 4 drives the robot arm body 5 to descend, and the robot arm body 5 uses its own hydraulic cylinder to drive the grabbing clamp to grab the chip. After grabbing, the motor 8 runs through the rotation of the rotating shaft 9, and then cooperates with the transmission belt to make the support column 6 drive the bracket 3 to deflect toward the side of the conveyor belt 11. When the motor 8 is deflected to the confirmed position, the robot arm body 5 releases the chip. The conveyor belt 11 is in a slow running state at this time. When the chip moves to the bottom of the U-shaped plate 12, the air pump 13 sucks through the two groups of ports of the three-way pipe 14 and the multi-group manifold 15, so that the dust and impurities remaining on the surface of the chip are taken away, and the chip is pre-cleaned, so that the chip can be automatically loaded while ensuring the cleanliness of the chip, reducing subsequent processing steps.
