Description

Parts sorting apparatus {Parts sorting apparatus}

The present invention relates to a component sorting device for sorting bolts of various sizes.

Among mechanical elements, screws used for combining and fixing parts are used in various products ranging from large machines to small electronic products.

In general, screws are classified as screws that are directly fixed to the female thread of the base material when tightening the assembly, and bolts that penetrate the base material and are tightened with a nut, and are usually called bolts in industrial settings.

The production of such bolts is based on mass production of various kinds of general bolts (especially in case of small size) in addition to special bolts of small quantity production used for special products. In mass production, defects inevitably occur due to obsolescence of processing machines, machine malfunctions and cumulative errors, and carelessness of workers.

Currently, most of the bolt defect screening tests are determined based on the subjective perception and judgment of the defect criteria of the operator.

This method is suitable for inspecting a small amount of parts in a short time, but has limitations in inspecting a large amount of various products for a long time.

As a means that can be applied to the inspection of many kinds of multi-products and can flexibly cope with various types of inspection items, a computer vision inspection system that is non-contact and capable of real-time inspection is the most effective.

Among them, as machine vision emerges as the core of the inspection process, it is becoming an important point in the manufacturing process while solving various problems such as securing the reliability of inspection results and replacing high wages.

Machine vision is a technology that obtains image data using electrical, optical, and non-contact technology, processes and analyzes the image, and derives a desired conclusion. Recently, it has been actively applied to parts inspection in Korea.

Registered Patent Publication No. 10-1296826 (name: Apparatus for selecting good quality of washer-mounting bolts) is a device for determining whether a bolt is good or not using machine vision. In the device for determining whether a washer-mounting bolt is good or not, a posture correcting device for correcting the posture so that the washer-mounting bolt reaches the machine vision camera for selecting a good product to have the same posture; A sorting device that supplies the washer-mounting bolts to a camera of machine vision and separates and discharges good and defective washer-mounting bolts according to the machine vision judgment, wherein the sorting device includes a feeding plate in which recesses spanning the heads of the supplied washer-mounting bolts are arranged at regular intervals; a guide plate that spans the groove of the feeding plate and guides the washer-mounting bolt that is rotatably supplied and has a discharge groove for collecting defective products; a rotating frame coupled to the feeding plate to transmit rotational force to the feeding plate, and around the circumference of which light holes for transmitting light are arranged at equal intervals equal to the concave grooves of the feeding plate; a driving device for rotating the rotating frame; And provided on the upper side of the feeding plate, the upper end is equipped with a posture correction device, the lower end is equipped with a light accommodated in the rotating frame, the light is positioned on the same line as the camera, and the posture correction device is a top plate mounted at an arbitrary point on a line parallel to the light.

Such a non-defective product sorting device can simplify a non-defective product judgment algorithm of machine vision for determining a non-defective product of washer mounting bolts supplied in irregular positions, and can reduce the time required for determining a non-defective product, thereby improving productivity.

In addition, since the washer-mounting bolts of good products are discharged by the discharge guide plate capable of moving in both directions around the rotating shaft, the box containing them can evenly contain the washer-mounting bolts. In addition, if there are two boxes containing the washer mounting bolts, the effect of being evenly contained as described above is lost, but the two boxes can be discharged at the same time, so the time delay due to the provision of the boxes is reduced as the time to put them in the boxes increases, eventually improving productivity.

However, in such a device for sorting good products, grooves are machined at regular intervals in the feeding plate, and the feeding plate is rotated by placing the head of the bolt in the groove in order to allow the bolt to be inspected to pass through the inspection position in a vertically erected state.

At this time, the driving devices (motor and feeding plate drive, etc.) required to rotate the feeding plate are usually installed below the feeding plate due to weight problems. As a result, it is difficult to utilize the space in the center. Therefore, the camera and various devices required to discharge good and defective products must be installed outside the feeding plate, requiring a relatively wide horizontal space. In addition, the camera for inspecting the thread part can be installed only on the outside of the feeding plate, and if the field of view of the feeding plate support and the bolt thread part overlaps, the shape of the thread part does not appear, so additional consideration is needed when arranging the groove machining interval.

However, when bolts of various dimensions are mixed, there were difficulties in classifying them.

In this embodiment, four supporters are disposed around the moving motor 20, and when classified, they are referred to as a first supporter, a second supporter, a third supporter, and a fourth supporter.

Unlike the present embodiment, only two supporters 40 may be disposed.

The moving motor 20 has a motor shaft disposed in a vertical direction, and a lower end thereof is fixed to the base 10.

A motor shaft is disposed toward the upper side of the moving motor 20, and the sorting housing 200 is assembled to the motor shaft.

The sorting housing 200 includes a rotary base 212 assembled to the moving motor 20 and rotated, a spiral guide 220, one end of which is formed to form a continuous surface with the upper surface 211 of the rotary base 212 and rises in a spiral along the edge of the rotary base 212, and a part connected to the spiral guide 220 and transported along the spiral guide 220. It includes a guide housing 250 that guides the selection assembly 300 .

The sorting speed can be improved.

Since the first selection grooves 1330 and the third selection grooves 1350 are formed in 6 different sizes, the first part can be dropped quickly before the first part falls in the first embodiment.

In particular, since the diameter of the first sorting distance is smaller than the diameter of the head of the second part and larger than the standard sorting distance, it is possible to prevent the second part from falling.

The shortest distance from the most concave point of the second sorting groove 1340 to the second outer circumferential surface 1325 is defined as the second sorting distance, and the shortest distance from the most concave point of the fourth sorting groove 1360 to the first outer circumferential surface 1315 is equal to the second sorting distance.

In this embodiment, a plurality of second sorting intervals are disposed between intermediate intervals in which the second standard sorting interval is gradually increased, so that the second part can be discharged/dropped quickly.

Therefore, the sorting assembly according to the present embodiment has the characteristic of minimizing that the mixed parts remain on the upper side of the first roller 1310 and the second roller 1320 even if the rotational speed of the moving motor 20 is increased to increase the supply speed of the mixed parts, and the sorting efficiency of the first part and the second part can be improved.
