Description

Technical Field

[0001] This utility model relates to the field of license plate processing, and in particular to an automatic license plate feeding electronic control system. Background Technology

[0002] License plates are a vehicle's "identity card," serving as crucial information to distinguish it from other motor vehicles. With economic development, the number of vehicles per capita has increased rapidly, leading to a corresponding surge in demand for license plates.

[0003] During the processing of license plates, the processed plates need to be stacked and stored uniformly; this process is called plate cutting. To avoid scratches and damage to adjacent plates during stacking, which would affect the quality of the finished product, paper is usually placed between them to separate and protect them. This process is usually still done manually, moving and placing the plates and paper, which is inefficient and incurs high labor costs over the long term. Therefore, an automatic cutting device is needed to automatically cut license plates, improving the automation level and work efficiency. Devices capable of automatic license plate cutting all have mechanical structures and electronic control systems; among them, the electronic control system is the key, controlling the mechanical structure to complete the automatic cutting work. Therefore, the quality of the electronic control system directly affects the practicality of the automatic license plate cutting device.

[0004] Therefore, an automatic license plate feeding electronic control system is proposed here. Utility Model Content

All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, an automatic license plate feeding electronic control system includes:

[0034] PLC controller, control switches, drive modules, and detection modules.

[0035] The PLC controller is electrically connected to the control switch, the drive module, and the detection module, respectively.

[0036] The control switch is used to input control commands.

[0037] The PLC controller is used to control the working state of the drive module according to control instructions.

[0038] Furthermore, the PLC controller has built-in automatic control programs corresponding to each control instruction.

[0039] The detection module is used to detect the operating status of the drive module and the storage status of the material station, and send the data to the PLC controller.

[0040] Example 2

[0041] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the control switch includes a start / stop button, a reset button, a mode switching switch, and a motor brake switch.

[0042] The start / stop button is used to issue start and stop commands.

[0043] The reset button is used to issue a reset command.

[0044] The mode switch is used to issue a command to switch the working mode.

[0045] The motor brake switch is used to protect the electronic control system. The motor brake switch can detect the status of the drive module (including the current and voltage of the drive module, etc.), and control the drive module to stop running when a fault occurs.

[0046] Furthermore, the control switch is a touch screen controller.

[0047] Example 3

[0048] like Figure 3 As shown, the difference between this embodiment and the previous embodiment is that it also includes a status display module, which is used to display the operating status of the electrical control system; the status display module is electrically connected to the PLC controller and receives status information sent by the PLC controller.

[0049] Furthermore, the status display module is a three-color indicator light. The three-color indicator light includes red, yellow, and green lights. A red light indicates a equipment malfunction requiring immediate shutdown and inspection. A yellow light indicates the equipment is preparing to run or is in standby mode. A green light indicates the equipment is running normally and in good condition.

[0054] Furthermore, the upper limit sensor and lower limit sensor of the material platform are magnetic induction switches; used to detect the storage status of the receiving box for storing license plates, ensuring that it can be replaced in time when it is full.

[0055] Furthermore, the material surface sensor of the material platform consists of a set of two infrared sensors, one for transmitting infrared signals and the other for receiving infrared signals. The material surface sensor detects whether the material platform is in the correct position, ensuring that the timing of license plate placement matches the timing of the receiving bin's placement at the workstation, thus guaranteeing that the receiving bin is in the appropriate position when the license plate is placed.

[0056] Example 6

[0057] The difference between this embodiment and the previous embodiment is that the PLC controller is a DVP32ES, and its connection wiring diagram is as follows. Figure 6 As shown.
