Description

Technical Field

[0001] This utility model relates to the field of printed circuit technology, and more specifically, to a feeding mechanism for an SMT pick and place machine. Background Technology

[0002] The feeding mechanism of an SMT pick-and-place machine, also called a feeder or feeder, is a key component in the SMT production line. It is responsible for accurately and quickly supplying electronic components to the pick-and-place machine for placement. The components are placed on a disc, which is rotated to a designated position by a motor. The placement head picks up the components from the designated position on the disc and places them onto the PCB. This article provides technical insights into the feeding mechanism.

[0003] The study of the feeding mechanism revealed the following problems:

[0004] The feeding mechanism places electronic components inside a disc. Since the disc has a spiral belt that rotates and transports the electronic components, when a large number of electronic components accumulate inside the disc, the electronic components can easily affect the normal transport of the belt. As a result, the feeding mechanism needs to add electronic components inside the disc periodically, and cannot transport a large number of electronic components at once.

[0005] Currently, the existing technology CN202310798134.1 discloses a feeding mechanism for an anti-deviation SMT placement machine. This utility model has a conveyor belt at the upper end of its main body, and a first bracket is provided above the front of the conveyor belt. A motor is fixedly installed above the first bracket, and the output end of the motor is fixedly connected to a first rotating rod. A first bevel gear, a forward thread, and a reverse thread are sequentially arranged on the outer side of the first rotating rod from front to back. A second bracket is rotatably connected to the end of the first rotating rod, and the main body is fixedly connected to the bottom end of the second bracket. This anti-deviation feeding mechanism for an SMT placement machine is equipped with an anti-deviation device. Since the material is easily deviated during transport on the conveyor belt, two limiting plates are provided, which can adjust the width. Rotating rollers are provided on the limiting plates, and these rollers are in contact with the material. When the conveyor belt transports the material, the rotating rollers rotate, which can limit the material and thus achieve the anti-deviation effect.

[0006] This invention mainly solves the problem that the feeding mechanism needs to add electronic components inside the disc at regular intervals, and cannot transport a large number of electronic components at once. Utility Model Content

[0007] The present invention aims to solve the problems mentioned in the background, thereby providing a feeding mechanism for an SMT pick and place machine.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a feeding mechanism for an SMT pick and place machine, comprising a base, a motor at the upper end of the base, a disc at the upper end of the motor, a material barrel at the lower end inside the disc, and a hopper penetrating the upper end of the material barrel.

[0009] Furthermore, the base is placed on the ground, the motor is connected to the power circuit via a power cord, and the motor's output shaft extends into the interior of the disc.

[0010] Furthermore, a belt is rotatably connected to the inner wall of the disc, and the motor drives the belt to rotate, thereby forming a rotary feeding mechanism.

[0011] Furthermore, the lower end of the hopper is provided with an opening, the opening of the hopper is 5-10cm away from the bottom wall of the disc, and the hopper extends to the top of the disc.

[0012] Furthermore, the opening of the material bucket is spaced 5-10cm from the bottom wall of the disc, which facilitates the entry of electronic components into the interior of the disc.

[0013] Furthermore, a pad is provided at the lower end of the inside of the material barrel, and a ball is rotatably fitted inside the pad. The upper end of the ball is oscillatingly connected to a bearing, and a washer ring surrounds the outside of the bearing.

[0014] Furthermore, the upper end of the pad has a groove, and the sphere is embedded in the groove to maintain circumferential rotation.

[0015] Furthermore, the bearings are arranged vertically inside the material barrel, the diameter of the gasket is 3-5 cm smaller than the diameter of the inner wall of the material barrel, and the gasket is concave.

[0016] 1. The feeding mechanism of this SMT pick and place machine, through the setting of the material bucket and hopper, can feed a large number of electronic components while avoiding the accumulation of electronic components inside the disc, which would affect the belt rotation and feeding. At the same time, it is convenient for the disc to feed a large number of electronic components at a time, avoiding the need to control the number of electronic components added inside the disc due to the presence of a belt inside the disc.

[0017] 2. After the electronic components inside the hopper of the feeding mechanism of this type of SMT placement machine enter the barrel, the electronic components fall to the upper end of the pad ring. Due to the different weights of the electronic components on both sides of the upper end of the pad ring, the pad ring drives the bearing to tilt and swing vertically. The bearing rotates 360° inside the pad block through the ball.

[0018] The tilt of the pad ring facilitates the falling of electronic components to the lower end of the material barrel. The pad ring also ensures uniform discharge of electronic components, preventing them from accumulating inside the disc. The pad ring also limits the discharge of electronic components from the lower end of the material barrel. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 In the embodiments of this utility model,

[0026] Example 1: A feeding mechanism for an SMT pick and place machine includes a base 1, a motor 101 at the upper end of the base 1, a disc 102 at the upper end of the motor 101, a material bin 201 at the lower end inside the disc 102, and a hopper 2 passing through the upper end of the material bin 201.

[0027] Wherein: base 1 is placed on the ground, motor 101 is connected to power circuit through power cord, and output shaft of motor 101 extends into disk 102;

[0028] A belt is rotatably connected to the inner wall of the disc 102, and the motor 101 drives the belt to rotate, thereby forming a rotary feeding.

[0029] The lower end of the material bucket 201 has an opening, and the opening of the material bucket 201 is 5-10cm away from the bottom wall of the disc 102. The hopper 2 extends to the top of the disc 102.

[0030] The opening of the material barrel 201 is 5-10cm away from the bottom wall of the disc 102, which facilitates the entry of electronic components into the interior of the disc 102;

[0031] By setting up the material bucket 201 and the hopper 2, a large number of electronic components can be fed at the same time, while avoiding the accumulation of electronic components inside the disc 102, which would affect the belt rotation and feeding. At the same time, it is convenient for the disc 102 to feed a large number of electronic components at a time, avoiding the situation where the disc 102 has a belt inside, which would require controlling the number of electronic components added inside the disc 102.

[0032] The electronic components first enter the interior of the hopper 2, and then enter the interior of the barrel 201 through the hopper 2. Since the opening of the barrel 201 is 5-10cm away from the bottom wall of the disc 102, it is convenient for the electronic components to enter the interior of the disc 102. The inner wall of the disc 102 is rotatably connected to a belt, and the motor 101 drives the belt to rotate, thereby forming a rotary feeding of the electronic components.

[0033] Example 2: Refer to the attached instruction manual Figure 2-4 The difference between Embodiment 2 and Embodiment 1 is that a pad 3 is provided at the lower end of the material barrel 201, a ball 301 is rotatably mounted inside the pad 3, a bearing 302 is oscillatingly connected to the upper end of the ball 301, and a washer ring 303 surrounds the outside of the bearing 302.

[0034] Wherein: the upper end of the pad 3 is provided with a groove, and the sphere 301 is embedded in the groove to maintain circumferential rotation;

[0035] Bearings 302 are arranged vertically inside the material barrel 201. The diameter of the gasket 303 is 3-5 cm smaller than the inner wall diameter of the material barrel 201. The gasket 303 is concave.

[0036] Wherein: After the electronic components inside the hopper 2 enter the material barrel 201, the electronic components fall to the upper end of the pad ring 303. Since the electronic components on both sides of the upper end of the pad ring 303 have different weights, the pad ring 303 drives the bearing 302 to tilt and swing in the vertical direction. The bearing 302 rotates 360° inside the pad block 3 through the ball 301.

[0037] The tilt of the pad ring 303 facilitates the falling of electronic components into the lower part of the material barrel 201. The pad ring 303 also enables uniform discharge of electronic components, preventing them from accumulating inside the disc 102. The pad ring 303 also limits the discharge of electronic components from the lower part of the material barrel 201.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
