[0019] like Figure 1-2 As shown, the present invention provides a motor switching device for a printing equipment, comprising a motor switching circuit, a stepper motor, and a servo stepper motor, wherein the stepper motor and the servo stepper motor are respectively connected to the motor switching circuit via signals.

[0020] The motor switching circuit includes a mode selection switch, a power relay, and a main control device.

[0021] Preferably, the mode selection switch includes a first mode driving circuit and a second mode driving circuit.

[0022] Preferably, the first mode driving circuit and the second mode driving circuit further include a first mode driving circuit interface U14 and a second mode driving circuit J9, respectively.

[0023] Preferably, the mode selection switch also includes the main interface J7.

[0024] The motor switching circuit, as the core hub of the entire device, consists of three key components: a mode selection switch, a power relay, and a main control unit. The mode selection switch is ingeniously designed, encompassing both a first-mode drive circuit and a second-mode drive circuit, providing users with diverse motor drive mode options. The first-mode drive circuit and the second-mode drive circuit are respectively equipped with interfaces U14 and J9, further ensuring the accuracy and stability of signal transmission. The mode selection switch also features a main interface J7, facilitating flexible connection and interaction with other devices.

[0025] Preferably, the main control device is connected to an external power supply via a relay.

[0026] Preferably, the relay is a 24V DC relay.

[0027] Preferably, the relay is also electrically connected to the stepper motor load device, and the stepper motor load device is signal connected to the main control device.

[0028] The central control unit is connected to an external power supply via a 24V DC relay, which not only reliably controls the power supply's on / off state but also provides stable power support for the entire device. Simultaneously, this relay is electrically connected to the stepper motor load device, which in turn maintains a signal connection with the central control unit, forming a complete and efficient control loop. This ensures that the printing equipment can flexibly and accurately switch motor operating modes according to actual needs, significantly improving the printing equipment's efficiency and performance.

[0029] In this utility model, J4 is the customer's stepper motor interface; D55, D56, D57, D58, D59, D60, D61, and D62 are the freewheeling diodes of the stepper motor; GND, the power supply of the 24V_STP stepper motor, is the system ground; U14 is TB6560, the stepper motor driver chip; RL1 and RL2 are 24V DC relays respectively; J11 is the servo stepper motor control signal interface for system control output; J9 is the interface for connecting the stepper motor output of the board; J8 is the interface for connecting J4; U1, U2, and U3 are optocouplers. Through the application of optocouplers U1, U2, and U3, the servo drive signals PUL+, PUL-, DIR+, DIR-, EN+, and EN- are made to follow the current loop mode, improving the anti-interference capability of external signals and avoiding false triggering of the motor; U5 is L7805CD2T, a 5V LDO chip; J10 is the 24V input, connecting to the 24V power supply box; J1 and J2 are connected to the sensing device; J3 J5 connects to the 5V input interface of the board; J39 is the relay selection switch signal;

[0030] The working principle of this utility model:

[0031] This invention controls two types of interface devices—stepper motors and servo stepper motors—by synchronously outputting signals through a central control device. These two types of motors are driven by a power relay, with the stepper motor mode selected by default.

[0032] Servo stepper drive mode: J4 is the interface for connecting to the customer's stepper motor device, U14 is the stepper motor driver IC, and J11 is the servo stepper motor interface of the system motherboard. The signals are PUL+PUL-DIR+DIR-EN+EN- respectively. This interface module is equivalent to a servo stepper driver, which can support stepper motor output with higher power. A servo driver costs hundreds or even thousands of dollars. The application of this module can greatly reduce the customer's machine setup cost in this scenario.

[0033] The motor driving mode allows customers to select the load motor and other motor devices. J7 is the interface for connecting the customer's stepper motor device, RL1 is the power relay, J9 is the interface for connecting the board's stepper motor output, J39 is the relay selection switch signal, and J8 is the interface for connecting to J4. By default, if the switch on J39 is not closed, J7 will connect to the signal on J9, and the motor output signal on J7 will be the output driver for the board's stepper motor. If the switch on J39 is closed, J7 will connect to the signals on J8-J4, and the motor output signal on J7 will be the output driver for U14. This connection method allows customers to select different motor drivers according to their actual usage environment without needing to change system settings, greatly reducing the customer's manpower and material costs. J1 and J2 are the sensor interfaces for connecting the front and rear limit switches of the motor. J3 and J5 are the 5V input interfaces of the board. RL2 is a signal-triggered relay. When the switch of J39 is closed, the signal of J1 will be connected to J3, and the signal of J2 will be connected to J5. This design is used in conjunction with switching the servo stepper drive mode to ensure that the motor can detect the front and rear position information.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
