According to a specific embodiment of the present invention, a control method for a tube bending device is provided, where the core bar detection device includes an image acquisition module, and the image acquisition module is configured to acquire a core bar image. The method comprises the following steps: when the core bar of the pipe bender is adopted to bend the pipe fitting, the image acquisition module detects the core print operation state of the core bar in real time, after the image acquisition module detects the head information of the core bar, the controller controls the core bar to drive the core print to execute retreating action, and when the image acquisition module detects that the core print is lost, the pipe fitting with the core print is taken out in time to prevent the pipe fitting with the core print from entering the pipe fitting bending machine and the pipe fitting with the core print.

The front of the core print is provided with an irregular round core print with the diameter of about 4mm, and the core print is mainly used for processing and forming a U-shaped pipe. If the air conditioner is lost, the air conditioner can flow into the U pipe and then enter the air conditioner, and the refrigerating effect is influenced. In this embodiment, by adopting the control method of the application, the pipe bender can be combined with the image acquisition device in the pipe bending process, whether the core bar falls off from the processed pipe fitting or not can be detected by the image acquisition device, and then the core bar withdrawing operation can be carried out, so that the reliability of housekeeper processing can be effectively improved, and the quality of the processed pipe fitting can be improved.

The black tube is a section of unqualified product detected by a manufacturer after production, and black is sprayed on the section of unqualified product in the prior art so as to be conveniently detected manually during use. All detect by the manual work in the past for the operating efficiency is low, and this application can improve operating efficiency and reliability through setting up image acquisition device.

After the bending operation of the pipe fitting by the core rod is finished, the core rod is withdrawn to a preset angle, and the image acquisition module can acquire the head image information of the core rod. Wherein the preset angle is 100 degrees. The preset time is two seconds.

According to another aspect of the present invention, as shown in fig. 1, there is provided a pipe bending apparatus as described above. The image acquisition module is provided with a photographing unit 6, a delay control module and a light source module 7. The photographing unit 6 is used for photographing the head of the core rod in the bending operation so as to obtain the head image information. After the core rod is withdrawn to the preset angle, the delay control module receives the delay preset time information, and the photographing unit photographs within the preset time to discharge the black tubes appearing in the machining process. The light source module 4 is disposed adjacent to the image capturing module, and the light source module 7 is configured to provide a light source to the image capturing module.

The pipe bending device further comprises a pipe bender, and the image acquisition module is arranged adjacent to the pipe bender.

Specifically, the image acquisition module includes installing support 5, installs and feels detection device, and the unit of shooing 6 shoots when the core rod head is exposed after the pipe fitting is bent, takes a picture and carries out the action of loosing core again after accomplishing. The long U pipe bender control system of the image acquisition module can be perfectly integrated, and whether the core rod head falls off can be well detected.

The long U-shaped pipe bending machine adopts a Huichuan H3U controller and selects a Huichuan servo motor. And an image acquisition module is arranged right above the bending swing arm of the pipe bender. The pipe bending device further comprises a touch screen display, a visual detection switch is arranged on the touch screen display, and visual detection delay setting can be carried out. The visual detection switch is firstly turned on, the pipe withdrawing motor starts to withdraw materials after the long U pipe bender bends a pipe, the bending starts to withdraw after the material withdrawing is finished, and the core pulling is finished at the moment.

Further, after the long U-shaped pipe bender bends and retreats to 100 degrees, the core bar can be exposed, and at this time, a signal M287 is triggered to the controller, so that the camera of the photographing unit 6 performs photographing detection. And after two seconds of detection, the core withdrawing action is started, and after the core withdrawing is finished. Feeding and the like can be carried out in advance, and normal butt joint of the long U-shaped pipe bender and the visual detection device can be realized because feeding does not reach the core print yet, so that the long U-shaped pipe bender and the visual detection device are integrated, and conditions are created for providing visual detection for the next processing flow. Wherein, the image acquisition mould passes through aluminium alloy 2 to be installed on installing support 5, and installing support 5 has crossbeam 1, and light source module 7 passes through light source seat 3 and is connected with aluminium alloy 2.
