There are many types of electronic components, which can be roughly divided into two categories, one is components, such as resistors, capacitors, inductors, etc., and the other is devices, such as transistors, diodes, field effect transistors and integrated circuits. With the development of electronic technology, electronic components are gradually developing towards miniaturization, light weight, high frequency, high current, low EMI, low manufacturing cost, and high reliability. In order to meet the above requirements, more and more electronic components need to be coated with glue on the product during processing.

The interiors of the two second transmission boxes are both rotatably connected with a first threaded rod, and the surface of the first threaded rod is threadedly connected with a first slider, and the first slider is slidably connected to the inner wall of the second transmission box.

[0026] However, although it can automatically feed through the tray during the dispensing operation, the number of electronic components that can be placed on the tray is limited, and it cannot realize continuous dispensing operations on electronic components. The dispensing efficiency is low and cannot meet the needs of modern production. In order to solve this technical problem, a conveyor belt 4, a mounting support 9, and a micro electric vacuum suction cup 10 are added to the application document.

[0027] According to the above content, in order to realize the continuous dispensing operation of electronic components and ensure the stability of electronic components during dispensing, it also includes a plurality of driving rollers 3 movably installed inside the mounting bracket 2, and the outer part of the driving roller 3 is sleeved with a conveyor belt 4, and a plurality of mounting supports 9 are arranged around the conveyor belt 4, and a placement frame 11 is arranged on the top of the mounting support 9, and the electronic components are restricted by the placement frame 11 to ensure the stability of the electronic components during dispensing, and a micro-electric vacuum suction cup 10 is fixedly installed inside the mounting support 9, and the micro-electric vacuum suction cup 10 is a common prior art, and the model can be XP50Z-24V, and the left and right sides of the mounting support 9 are provided with conductive components 12 that cooperate with the micro-electric vacuum suction cup 10, and the left and right sides of the mounting bracket 2 are fixedly installed with a mounting back plate 13, and the inside of the mounting back plate 13 is fixedly installed with a conductive copper plate 14, and the conductive copper plate 14 is electrically connected to the power supply equipment in the prior art.

The glue gun 8 is a common prior art, and its principle and use process are not described here. The glue gun 8 can perform glue dispensing operations on electronic components. A discharge port 16 located below the conveyor belt 4 is arranged at the tail of the mounting base 1. When the micro-electric vacuum suction cup 10 moves to the tail of the conveyor belt 4, the conductive component 12 is disconnected from the micro-electric vacuum suction cup 10, and the micro-electric vacuum suction cup 10 is powered off to release the adsorption of electronic components. The electronic components can be discharged along the discharge port 16 to achieve automatic discharge.

[0028] As a further implementation scheme of the above technical scheme: the driving rollers 3 are evenly distributed inside the mounting bracket 2, and the driving rollers 3 and the conveyor belt 4 are in a tight fit, ensuring that the driving rollers 3 can drive the conveyor belt 4 to rotate stably and prevent the conveyor belt 4 from slipping, thereby improving the accuracy of glue dispensing. A transmission assembly 6 is provided at one end of the driving roller 3 away from the stepper motor 7. The output shaft of the stepper motor 7 is fixedly connected to a group of driving rollers 3 at the inner head of the mounting bracket 2. The stepper motor 7 is a common prior art, and the model BSHB3913 can be selected. The stepper motor 7 drives the conveyor belt 4 to rotate intermittently, so that the electronic components can be continuously and intermittently transported, and the glue dispensing gun 8 can perform glue dispensing operations on the electronic components during the intervals.

[0029] As a further implementation scheme of the above technical scheme: the transmission assembly 6 includes a transmission chain and a plurality of transmission sprockets. The number of the transmission sprockets is the same as that of the driving roller 3, and the transmission sprocket is fixedly mounted on the end of the driving roller 3 away from the stepper motor 7. The transmission chain is meshingly mounted on the outside of the transmission sprocket. The transmission is transmitted through the transmission sprocket and the transmission chain to ensure that the stepper motor 7 can drive the plurality of driving rollers 3 to rotate synchronously, thereby providing sufficient power for the rotation of the conveyor belt 4, thereby driving the conveyor belt 4 to rotate stably.

[0030] As a further implementation scheme of the above technical scheme: connecting bases 5 with the same number as the mounting supports 9 are arranged on the circumferential side of the conveyor belt 4, and the mounting supports 9 are fixed on the connecting bases 5 by screws. By setting the connecting bases 5, an installation position is provided for the mounting supports 9, ensuring that the conveyor belt 4 can drive the mounting supports 9 to rotate, thereby realizing the adjustment of the position of the electronic components.

[0031] As a further implementation scheme of the above technical scheme: the conductive component 12 includes a positioning plate 121, a conductive connecting rod 122, a transmission ring 123, and a compression spring 124. The positioning plate 121 is fixedly installed on the side of the mounting support 9, and the conductive connecting rod 122 is movably installed on the end of the positioning plate 121. A transmission ring 123 is arranged on the conductive connecting rod 122. By setting the transmission ring 123, the elastic force of the compression spring 124 can act on the conductive connecting rod 122. The external movable sleeve of the conductive connecting rod 122 is provided with a compression spring 124. The micro-electric vacuum suction cup 10 is electrically connected to the conductive connecting rods 122 in the conductive components 12 on both sides. When the mounting support 9 rotates to the top of the conveyor belt 4, the conductive connecting rods 122 in the conductive components 12 on both sides of the mounting support 9 are snapped into the mounting back plate 13 on the corresponding side and are against the conductive copper plate 14, so as to realize the power supply of the micro-electric vacuum suction cup 10. The micro-electric vacuum suction cup 10 adopts a low-voltage power supply below 36 volts, which is safer.

[0032] As a further implementation of the above technical solution: The compression spring 124 always applies an elastic force to the conductive connecting rod 122. The end of the conductive connecting rod 122 can be inserted into the interior of the mounting backplane 13 and abuts against the conductive copper plate 14. The conductive connecting rod 122 is electrically connected to the micro electric vacuum chuck 10. By applying an elastic force to the conductive connecting rod 122 through the compression spring 124, the end of the conductive connecting rod 122 can closely adhere to the conductive copper plate 14, ensuring the conductivity between the conductive connecting rod 122 and the conductive copper plate 14, and thus realizing stable power supply to the micro electric vacuum chuck 10.

[0033] As a further implementation of the above technical solution: The cross-sectional shape of the mounting backplane 13 is in a "U" shape. The head of the conductive copper plate 14 is provided with a guiding inclined surface 15 that cooperates with the conductive component 12. Since the conductive connecting rod 122 is affected by the elastic force of the compression spring 124, interference is likely to occur when the conductive connecting rod 122 and the conductive copper plate 14 are initially mated.

[0034] Working principle:

[0035] When using the present utility model, through the transmission of the transmission component 6, the stepping motor 7 drives a plurality of driving rollers 3 to rotate intermittently, and then drives the conveyor belt 4 to rotate intermittently. Through a manipulator in the prior art, the electronic components to be dispensed are placed one by one in the placement frame 11 on the top of the mounting support 9 at the head position of the conveyor belt 4. The conveyor belt 4 drives the placed electronic components to move intermittently to the bottom of the dispensing gun 8. When the electronic component moves into place, the dispensing gun 8 performs a dispensing operation on the electronic component. Through the continuous conveyance of the electronic components by the conveyor belt 4 and dispensing the electronic components by the dispensing gun 8 during conveyance, continuous dispensing operation of the electronic components is realized. When the mounting support 9 moves to the head position at the top of the conveyor belt 4, the micro electric vacuum chuck 10 in the mounting support 9 is connected to the conductive copper plates 14 at the corresponding positions on both sides through the conductive components 12 on both sides to supply power to the micro electric vacuum chuck 10. The electronic components placed on the top of the mounting support 9 are adsorbed by the micro electric vacuum chuck 10 to ensure the stability of the electronic components during dispensing. When the micro electric vacuum chuck 10 moves to the tail of the conveyor belt 4, the conductive components 12 on both sides of the micro electric vacuum chuck 10 are disconnected from the conductive copper plates 14, and the micro electric vacuum chuck 10 is powered off. During the continuous rotation of the conveyor belt 4 driving the mounting support 9 and the micro electric vacuum chuck 10, the dispensed electronic components on the top of the mounting support 9 fall into the blanking port 16 and are discharged along the blanking port 16 to realize automatic blanking.
