Embodiment 1

[0044] refer to Figure 1~Figure 5 , an embedded mold protection system based on ZigBee network, the whole system consists of multiple sets of mold protectors (terminal nodes), multiple routing nodes, a coordinator node and a PC, such as figure 1 shown.

[0045] One disadvantage of conventional mold protectors is that after abnormality is detected, an alarm is issued only through a buzzer and a display unit. In this case, when a worker needs to monitor multiple devices, constant patrolling is necessary. Considering the existence of this situation, the present invention designs a single mold protector as a wireless sensor node with data wireless transmission and reception capabilities, builds a ZigBee wireless network with the mold protector as the terminal node in the workshop, and realizes remote monitoring of the mold state .

[0046] Firstly, further explain the wireless sensor network based on ZigBee technology. The network contains a terminal node, multiple routers an...

Embodiment 2

[0062] A single mold protector is implemented as Figure 5 As shown, the specific steps are as follows:

[0063] Step 1: After injection molding, the main control board waits for the mold opening signal. When the injection molding machine opens the movable mold to the maximum position, the signal is sent to the main control board through the I / O signal adapter board. At this time, the main control board waits After a set delay time (to ensure that a clear image can be taken), the infrared camera is controlled to capture the cavity image at this time. It should be emphasized that the reason why the infrared light source and infrared camera are used is that the images captured by ordinary cameras are easily affected by light changes and cause false detection by the system, while the infrared camera only accepts images of specific bands. This effect.

[0064] Step 2: Due to the vibration of the industrial site and the inaccurate return of the moving model, it is easy to cause p...

Abstract

The invention relates to an embedded type mold protection system based on a ZigBee network. The system comprises a coordinator, a router node, an embedded type mold protector with a wireless transceiver function, and a host computer. The coordinator is in charge of the establishment and maintenance of the ZigBee network, the addition of child nodes, data collection, and communication between the network and the host computer. The router node is in charge of data routing, and is used for ensuring correct data exchange between a main node and the embedded type mold protector with the wireless transceiver function. The embedded type mold protector with the wireless transceiver function is used for monitoring the safety of the mold, and is used for providing mold information. The host computer is used for displaying the real-time status of each terminal node in the system. The invention also provides an embedded type mold protection method based on the ZigBee network. The invention provides a remote monitoring scheme of the safety of an injection molding machine. With the scheme provided by the invention, mold safety and product quality of the injection molding machine can be ensured.

Description

technical field [0001] The invention relates to the field of molds for injection molding machines, in particular to a mold protection system for injection molding machines. Background technique [0002] Plastic injection molding machines have been used as processing equipment for plastic products for more than half a century. In recent years, with the continuous expansion of the application field of plastic products, the demand for injection molding machinery in the world has shown a trend of continuous and substantial increase. Especially in our country, since the 1990s, the sales of injection molding machines have grown rapidly at an average annual growth rate of about 10%, and the total output has ranked first in the world. [0003] In injection molding production, injection molds are the most important molding equipment for injection molding products, and their quality is directly related to the quality of products. And because the mold occupies a large proportion in th...
