Description

Technical Field

[0001] The present invention relates to an injection molding machine automation system. Background Art

[0002] Nowadays, injection molding machines are widely used as common equipment. Since traditional product parts have different molds, different specifications, sizes, and shapes of molds need to be dealt with in the injection molding machine to meet the processing of various products. This has led to the fact that injection molding machine equipment is doomed to be unable to produce efficiently and quickly. Especially for traditional injection molding machines, manual mold assembly is required, followed by feeding. After injection molding, mold cutting, mold opening, and material collection are needed. Thus, it is very difficult to achieve automation.

[0003] In order to improve the intelligence of the factory, manufacturers often purchase a large number of intelligent devices to meet the existing production requirements. However, the injection molding machine itself belongs to conventional technology, and the difference in products only lies in the molds. Once the mold is made, the injection molding machine only needs to perform injection molding. Therefore, how to quickly carry out injection molding production is reflected in the loading and unloading device supporting the injection molding machine.

[0004] Without purchasing new equipment, only by installing a new manipulator for the injection molding machine can manual feeding be changed to automatic feeding. However, if the efficiency of the injection molding machine is to be improved, another mold needs to be immediately fed into the equipment for injection molding after one mold production is completed. This is a dual injection molding mode for traditional injection molding machines. Although this production method greatly improves production efficiency, if the supporting manipulator cannot be intelligent, it will only increase the burden of manual operation and cannot bring economic benefits to the factory. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide an injection molding machine automation system, aiming to control the loading and unloading of the manipulator through the system, set the traditional injection molding machine to a dual injection molding mode, improve production efficiency while reducing labor costs, and use the system to replace manual operation.

[0006] To solve the above technical problems, the technical solution of the present invention is: an injection molding machine automation system, including a main control system, which controls the start and stop of the injection molding machine and the operation of loading and unloading; a feeding system, an injection molding system and a discharging system are provided in the main control system; wherein the feeding system includes a first specification feeding system and a second specification feeding system, and the two operate at intervals. After the first specification feeding system finishes execution, the second specification feeding system will be executed. After the second specification feeding system finishes execution, the first specification feeding system will be repeated, and so on to form a double injection molding mode; the injection molding system controls the injection molding machine itself, and after detecting that the feeding system fixes the mold in the equipment, it executes the injection molding work to complete the injection molding production; the discharging system includes a detection system, a mold cutting system and a discharging system; the detection system uses visual detection to observe the overflow state around the mold, judge whether the injection molded product is qualified, directly send the unqualified products to the waste area, and the qualified products enter the mold cutting system for mold cutting and mold opening, and then use a pressure device to demold the mold and send the product into the discharging system. The discharging system detects the product specifications and classifies and stores the products to complete the production.

[0007] Further, the feeding system includes a mold assembly module and a moving module. The mold is assembled by a manipulator and then clamped and sent into the injection molding machine. When the first specification feeding system and the second specification feeding system distinguish and clamp the mold parts for feeding according to the visual sensor, fixtures corresponding to different specifications are assembled.

[0008] Further, an overflow detection module is provided in the detection system. Whether the product is qualified is determined by the overflow size of the mold during mold closing, and the detection is realized by covering the mold with a detection fixture, and a two-way comparison is carried out with the visual detection.
