Description

Technical Field

[0001] The present invention relates to a feeding structure, and more particularly to an automatic sorting and feeding device for small parts. Background Art

[0002] Under the background of the booming development of modern manufacturing, the processing and assembly of small parts play an important role in many production fields. From precision electronic devices to small mechanical products, the efficient feeding of small parts has become a key link in improving production efficiency and product quality. However, the traditional feeding methods for small parts have many limitations. In the early production process, manual feeding was the most common method. Workers needed to manually place small parts onto the processing equipment one by one. Although this method could ensure the flexibility of operation to a certain extent, the efficiency was extremely low. With the continuous growth of market demand and the increasing requirements for product output, the speed of manual feeding was far from meeting the rhythm of large-scale production. Moreover, long-term repetitive manual operations were likely to cause fatigue among workers, resulting in an increase in the error rate of operations. For example, in the production of some products with strict requirements for the installation order of parts, manual feeding might result in incorrect sorting of parts, which would not only cause product quality problems but also lead to subsequent rework, further increasing production costs and time costs. In addition to the problems of manual feeding, in actual production, many small parts involve screw installation, and the existing feeding and related technologies often do not have the function of automatically tightening screws. This means that after the feeding of small parts is completed, additional manual labor or other equipment is required for screw tightening operations. This not only increases the production steps and prolongs the production time, but also it is difficult to achieve exactly the same force control when manually tightening screws, which may cause the screws to become loose or too tight, affecting the stability and service life of the product. If other equipment is used for screw tightening, additional equipment procurement costs and space are required, further increasing production costs and management difficulties.

[0003] Therefore, those skilled in the art are committed to providing an automatic sorting and feeding device for small parts that can effectively solve the above technical problems. Summary of the Invention

[0059] a grasping and tightening mechanism 6, which is arranged directly above the positioning assembly 7 and is used to grasp the small parts conveyed by the clamping mechanism 3. After conveying them to the positioning assembly, the small parts are tightened onto the workpiece;

[0060] a positioning assembly 7, which is used to position the workpiece;

[0061] a conveying mechanism 8, which is used to convey the workpiece to the positioning assembly 7 and transport it away after processing;

[0062] a manipulator 9, which is arranged on one side of the conveying mechanism 8 and is used to clamp the workpiece on the conveying mechanism 8 to the positioning assembly 7 and clamp the processed workpiece back onto the conveying mechanism 8.

Under the action of the magnetic field, the armature of the vibration source is attracted by the electromagnetic force and moves relative to the electromagnetic coil, and the spring plate deforms. When the electromagnetic force disappears, the spring plate returns to its original state. This process repeats, causing the chassis to generate high-frequency and small-amplitude vibrations.

[0070] This vibration is transmitted from the chassis to the spiral track. The materials on the track are affected by the frictional force with the track surface and their own inertial force under the action of the vibration. Since the vibration direction has a certain angle with the track plane, the materials move continuously upward along the spiral track under the combined action of the frictional force and the inertial force, and finally reach the track outlet, completing the conveying process from the bottom in a spiral upward manner.

The material clamping mechanical finger 33 and the drive assembly are both prior arts.

[0076] It further includes a second support platform 35 connected to one side of the first support platform 15. The upper end of the second support platform 35 is lower than that of the first support platform 15;

A displacement plate 38 is arranged below the second support platform 35. Four corners of the displacement plate 38 are slidably sleeved on respective columns 37. A moving cylinder 39 is arranged on the top plate 36. The output end of the moving cylinder 39 is connected to the upper end of the displacement plate 38. A material grasping manipulator 9 is arranged at the lower end of the displacement plate 38. The material grasping manipulator 9 is driven by a tightening motor to rotate.

[0078] The material positioning assembly 7 includes a positioning seat 50 arranged on the second support platform 35. A positioning table 51 is arranged on the positioning seat 50. A plurality of positioning holes 52 are formed in the positioning seat 50. Two parallel positioning grooves 53 that cooperate with the respective positioning holes 52 are formed in the second support platform 35;

[0079] Above the positioning table 51, there is a first positioning assembly 56 and a second positioning assembly 55 connected to the second support platform 35.

[0080] The conveying mechanism 8 includes a conveying frame 57, on which there are two conveying chains 59 driven by a conveying motor 58, and a number of feeding components 60 are placed on the conveying chains 59;

[0084] When this small part automatic sorting and loading device works, multiple components cooperate to realize the automatic process of small parts from temporary storage to tightening of the processed parts. The specific working principle is as follows:

[0085] After the controller of the bowl-shaped plug feeding mechanism 1 is turned on, the electromagnetic coil of the vibrating bowl is energized to generate an alternating magnetic field. Under the action of the magnetic field, the armature of the vibration source is attracted by the electromagnetic force and moves relative to the electromagnetic coil, and the spring piece deforms; when the electromagnetic force disappears, the spring piece returns to its original state, and so on, causing the chassis to generate high-frequency and micro-amplitude vibrations. This vibration is transmitted through the chassis to the spiral track 12. The small parts on the track move continuously upward along the spiral track under the combined action of frictional force and their own inertial force, and finally reach the output end through the extended conveying channel 13, completing the conveying process of spiraling upward from the bottom;

[0086] The pushing mechanism 2 is arranged on the first support platform 15. The pushing cylinder 17 acts, pushing the push plate 18 to slide on the first guiding rod 20, and then driving the push rod 21 and the push head 22 to move. The push rod 21 passes through the first notch 23 and the second notch 27 on the extended conveying channel 13 and enters the extended channel 26, pushing the small parts at the output end of the extended conveying channel 13 to the clamping mechanism 3.

[0087] The lifting cylinder of the lifting assembly 5 operates to drive the lifting plate 28 to move up and down along the second guide rod 29. The material clamping mechanism 3 is arranged on the lifting plate 28 and moves accordingly. When the small parts are pushed to the material clamping mechanism 3, the displacement cylinder 31 operates to move the drive box 32. The material clamping mechanical fingers 33 clamp the small parts under the drive of the drive assembly. Then, the lifting cylinder operates again to convey the material clamping mechanism 3 and the clamped small parts upward to the material grasping and tightening mechanism 6.

[0088] The moving cylinder 39 of the material grasping and tightening mechanism 6 operates to drive the displacement plate 38 to move up and down along the column 37. The material grasping manipulator 9 is arranged at the lower end of the displacement plate 38 and moves accordingly. After the material clamping mechanism 3 conveys the small parts in place, the material grasping manipulator 9 grasps the small parts. The moving cylinder 39 operates again to convey the small parts to the positioning assembly 7 by the material grasping manipulator 9. Subsequently, the material grasping manipulator 9 rotates under the drive of the tightening motor to screw the small parts onto the workpiece.

[0089] The conveying motor 58 of the conveying mechanism 8 drives the conveying chain 59 to operate, driving the material conveying assembly 60 placed on the conveying chain 59 to move. The positioning plate 16 and the positioning posts are arranged on the placing plate 61 of the material conveying assembly 60 for placing and preliminarily positioning the workpiece. The anti-collision posts 62 at the edge can prevent the workpiece from being damaged by collision. The manipulator 9 clamps the workpiece at the loading platform 63 of the conveying mechanism 8 onto the material positioning table 51 of the material positioning assembly 7. The positioning holes 52 on the positioning seat 50 cooperate with the positioning grooves 53 on the second support platform 35 to accurately position the workpiece. The first positioning assembly 56 and the second positioning assembly 55 further fix the workpiece from above. After the processing is completed, the manipulator 9 clamps the workpiece back to the conveying mechanism 8 and conveys it to the unloading platform 64 by the conveying chain 59 for transportation. During the conveying process, if the separation operation of the material conveying assembly 60 is required, the power box 67 of the separation assembly 65 drives the separation plate 66 to move upward. The separation plate 66 jacks up the material conveying assembly 60 to separate it from the conveying chain 59. The lower end of the separation plate 66 is connected to the fifth guide rod 68 to ensure smooth movement.
