Description

Technical Field [0001] The present invention relates to a vision inspection and loading system,

[0001] The present invention relates to an injection-molded product inspection and loading system, and more particularly, to a method of inspecting an injection-molded hollow disc or a ring-shaped injection product and automatically classifying the injection product according to the result of the vision inspection, And an injection system vision inspection and loading system for automatically collecting and stacking an injection object.

The injection molding is an injection molding method for producing at least one or more materials integrally by injecting a material melted at a high pressure into a cavity of an injection mold apparatus and injection molding the injection mold according to the shape of the cavity, The injection molding is carried out in a manner of filling and injection molding. Therefore, the production time is short and it is suitable for the production and has the advantage of obtaining a product having high mechanical properties. And is widely used.

In particular, with the development of robotic technology, product precision and high performance required, an injection automation system using a servo robot and an end effector has been introduced. Such an injection automation system is designed to meet the precision and high performance of a product But also unnecessary labor and process time can be reduced.

In general, since the quality of the product is influenced by the external dimensions and the surface condition of the injection-molded product through precision control, the vision inspection process for inspecting the surface of the injection product must be performed after all the processes are performed.

Injection molding products that have been injection-molded by the injection automation system and passed through the vision inspection are loaded onto trucks and transported to the requesting company. Accordingly, prior to loading into the transportation means, a process of arranging the injection products produced by the injection of the molds in a manner suitable for transportation should be carried out.

Conventionally, various studies have been conducted on vision inspection to improve the reliability, accuracy and convenience of inspection, but there has been no research on a process for loading an injection object passed through vision inspection to be suitable for transportation. Particularly, in the case of conventional vision inspection, the process is delayed because it is performed independently as a separate process regardless of the stacking process, and the process is complicated.

Accordingly, although the process of arranging and loading the injection objects passed through the vision inspection has been performed mainly through manpower, the work through such manpower increases manpower consumption and labor costs and has a disadvantage of delaying the process time.

1 is a plan view showing a vision inspection apparatus disclosed in Korean Patent No. 10-1358109 (entitled "Vision Inspection Apparatus Having Object Guiding Function").

The vision inspection apparatus 100 of FIG. 1 includes a supply unit 111 for supplying an object N, a transfer unit 111 for transferring an object to be supplied from the supply unit 111 in a slidable manner, A camera 170 for photographing an object to be conveyed through the conveying unit 120; a conveying unit 120 installed at a downstream end of the conveying unit 120 for passing a surface inspection; A defective part discharge unit 183 provided at the downstream end of the transfer unit 120 for discharging defective products which have not passed the result of the surface inspection, And a pneumatic nozzle 185 for moving the object to the good product discharge portion 181 or the defective product discharge portion 183.

The conventional technique 100 configured as described above analyzes the image captured by the camera 170 to perform surface inspection and drives the pneumatic nozzle 185 according to a result of the surface inspection to detect the object N 181) or a defective product discharge unit 183.

However, since the prior art 100 does not disclose any technique and method for loading the object to be discharged through the good article discharging portion 181 or the bad article discharging portion 183, a separate attraction force is required to load the collected object Therefore, unnecessary labor and labor costs are increased, and the process time is delayed.

Although the prior art 100 is configured to change the direction in which the object N is inserted through the pneumatic pressure of the pneumatic nozzle 185, this configuration is useful when the object N is of a weight below the threshold, There is a disadvantage in that separate or non-defective products are not accurately classified and additional equipment for periodically generating air pressure is required.

On the other hand, there are various studies on a loading system for carrying out the vision inspection or carrying out the final process on the object to be suitable for transportation.

FIG. 2 is a perspective view showing an automatic injection device for an injection molding disclosed in Korean Patent Laid-Open No. 10-2009-0021748 (entitled "Automatic injection device for injection molding").

2 is a block diagram illustrating an automatic filling apparatus 200 according to an embodiment of the present invention.

It is possible to automatically load the article 290 on the loading box 241 without separately arranging the article 290 by loading the loaded article on the loading box 241. [

However, in the conventional art 2 200, since the mounting grooves 242 on which the injection molding 290 is mounted are formed on one side of the loading box 241, the loading slot 242 having the mounting groove 242 corresponding to the size and shape of the injection molding 290, (241) must be manufactured separately, which leads to an increase in manufacturing cost and a complicated process.

In addition, as in the conventional art 2 (200), a method of loading an injection object using a separate loading box 241 is such that due to its own volume of the loading box 241, unnecessary space consumption is increased at the time of loading the transportation means, A problem arises.

The conventional art 2 200 is useful for an injection molded article having a predetermined volume and area because the injection molded body 290 is mounted on the mounting recess 242 in a one-to-one manner. However, when applied to an injection molded article having a small volume, And the efficiency is deteriorated.

Further, in the conventional art 2 (200), since it is carried out after the vision inspection process, and it is assumed that an article of good product passed the vision inspection is loaded, it is separated from the vision inspection process and independently operated, And the installation and operation costs are increased.

That is, 1) the process of sorting the good or defective product according to the result of the vision inspection and the process of collecting and stacking the classified products classified as good products are performed at the same time, thereby shortening the process steps to reduce the process time, And 2) it is urgent to study injection system vision inspection and loading system which can increase the load ratio compared with the space consumption by collectively arranging the injection products of good products without using a separate loading box.
