The visual sensor 107 collects the size data of the molding bricks from multiple angles, collects and focuses the light reflected or emitted by the object, and transmits it to the image sensor in the form of light. The principle is that when the light is irradiated onto the photosensitive surface of the image sensor, the photosensitive element will produce a change in charge or voltage, and this change is related to information such as the intensity and color of the light; the image sensor will convert these charges or voltages into a single charge or voltage. The voltage change is converted into an electrical signal; the electrical signal is converted into a digital signal through an analog-to-digital converter, and then the digital signal is transmitted to the image processor for processing. The image processing includes image denoising, enhancement, segmentation, feature extraction, etc. The visual sensor 107 compares the processed image with the reference image or preset standard stored in the memory. The reference image or standard is set in advance and is used to determine whether the detected object meets the requirements.

[0110] At the same time, when making hollow bricks, the size of the extrusion pressure is also crucial. During extrusion, the pressure accumulates in the middle. The pressure sensor 1136 is used to detect the molding state of the brick blank. The pressure sensor 1136 monitors the molding pressure of the brick blank in the mold in real time. When the pressure reaches the set value, the system automatically controls the compaction device to stop working or actively reminds. Semi-automatic control is achieved manually, which can ensure that the compaction degree of each hollow brick is uniform and consistent, thereby improving product quality. The detection principle of the pressure sensor 1136 is an existing technology and will not be repeated.

[0111] The hollow brick forming device can produce hollow bricks of the same specifications at one time, or can control the specifications separately and produce hollow bricks of different specifications at one time. In addition, the hollow forming device can realize flexible switching of hollow shapes without the need for additional mold replacement, thus realizing the function of one mold for multiple uses.
