To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0049] Example 1

[0050] Please see Figure 1 This invention provides a method for controlling a positioning device in a printing equipment, the steps of which are as follows:

[0051] S1: A sensing sensor is set at the zero point position of the X motor direction of the printing device; wherein the X motor direction is the inkjet movement direction, and the sensing sensor is used to sense whether the printing carriage is at the zero point position.

[0052] refer to Figure 2 A sensing sensor is set at the zero point position of the X motor direction of the printing device, wherein the X motor direction is the inkjet movement direction and the inkjet movement direction is the crossbeam scanning direction.

[0053] A sensing sensor is installed at the zero point position to monitor whether the printing carriage is at the zero point position.

[0054] When the printing carriage moves and prints on the crossbeam, the printing carriage will not be at the zero point position. When the printing carriage finishes printing an area, it will stop at a position and wait for the next area to be printed. The stopping position is the zero point position.

[0055] S2: Control the sensor to send a sensing signal to the preset control device of the printing equipment.

[0056] Specifically, when the sensing sensor detects a change in the state of the printing carriage, the sensing sensor automatically generates a corresponding sensing signal and controls the sensing sensor to emit the corresponding sensing signal to the preset control device of the printing settings.

[0057] The transformation refers to whether the printed car is at the zero point position.

[0058] S3: Connect the preset control device and the positioning device, and control the preset control device to open or close simultaneously with the positioning device according to the sensing signal, wherein the positioning device is set in the printing platform for positioning the printing medium.

[0059] Specifically, the preset control device and the positioning device are connected, and the switching state of the positioning device is controlled according to the switching state of the preset control device. When the sensing sensor does not detect that the printing carriage is at the zero point position, that is, when the printing carriage is moving, a corresponding sensing signal is sent to the preset control device to control the preset control device to turn off, and the positioning device is turned off; when the sensing sensor detects that the printing carriage is at the zero point position, that is, when the printing carriage stops, a corresponding sensing signal is sent to the preset control device to control the preset control device to turn on, and the positioning device is turned on, thereby ensuring that the positioning device is not accidentally activated, which would cause the printing carriage to collide with the positioning device.

[0060] In this embodiment, a sensing sensor is set at the zero point position of the X motor direction of the printing equipment. The sensing sensor detects whether the printing carriage is at the zero point position and controls the sensing sensor to send a sensing signal to the preset control device of the printing equipment. The preset control device is connected to the positioning device. According to the sensing signal, the preset control device is controlled to open or close, and the positioning device is controlled to open or close simultaneously, so as to avoid accidental activation of the positioning device switch during the printing process, which could cause damage to the nozzle of the positioning device.

[0061] In one embodiment, the sensing sensor is neither a photoelectric limit switch nor a mechanical limit switch. The photoelectric sensor determines whether the printing carriage is at the zero point position based on information such as changes in light and shadow or light intensity; the mechanical limit switch determines whether the printing carriage is at the zero point position based on current.

[0062] The installation sensor is located at the zero point of the X motor direction of the device. Before the printing carriage starts printing, the sensor starts to sense and detect the target position through the sensing element or sensor component. When the target position is detected, the sensor determines whether there is a printing carriage at the zero point of the X motor direction of the device.

[0063] In one embodiment, such as Figure 3 As shown, the preset control device for controlling the sensing sensor to send sensing signals to the printing equipment includes:

[0064] S21: When the sensing sensor detects that the printing carriage is at the zero point position, a first signal is sent to the preset control device;

[0065] S22: When the sensing sensor detects that the printing carriage is not at the zero point position, a second signal is sent to the preset control device.

[0066] Specifically, when the sensor detects a printing carriage at the zero point position, the sensor generates a first signal, which is then sent to the preset control device of the printing equipment.

[0067] When the sensor detects that there is no printing carriage at the zero point position, the sensor will automatically generate a second signal, which will then be sent to the preset control device of the printing equipment.

[0068] In one embodiment, such as Figure 4 As shown, the connection between the preset control device and the positioning device, and the control of the preset control device to open or close simultaneously with the positioning device based on the sensing signal, includes:

[0069] S31: When the sensing signal is the first signal, control the preset control device to turn on; when the preset control device is turned on, the positioning device is turned on.

[0070] S32: When the sensing signal is the second signal, control the preset control device to turn off; when the preset control device is turned off, the positioning device is turned off.

[0071] Specifically, the preset control device is connected in series with the positioning device, and the on / off states of the preset control device and the positioning device are consistent. That is, when the preset control device is on, the positioning device is also on; when the preset control device is off, the positioning device is also off. Controlling the on / off state of the preset control device to be the same as the on / off state of the positioning device ensures that even if the positioning device switch is accidentally touched during the printing process, the positioning device switch will not be turned on.

[0072] The preset control device receives the sensing signal from the sensing sensor, analyzes the sensing signal, and controls the preset control device to turn on when the sensing signal is determined to be the first signal. At the same time, the positioning device detects the status of the preset control device. When the preset control device is detected to be turned on, the positioning device turns on.

[0073] When the preset control device receives the sensing signal from the sensing sensor, it analyzes the sensing signal and determines that the sensing signal is the second signal. At the same time, the positioning device detects the status of the preset control device. When it detects that the preset control device is closed, the positioning device cannot be turned on.

[0074] During the printing process, if the printing carriage leaves the zero position of the X motor direction of the device due to external force or other factors, the sensing sensor will immediately send a second signal to the preset control device when it detects that the printing carriage is not in the zero position. After receiving the signal, the preset control device will change from on to off, and the positioning device will also change from on to off. When the positioning device changes from on to off, it will retract in time to ensure that the positioning device will not collide with the device and the print head.

[0075] Preferably, the preset control device can be a relay switch, which is more reliable, has a longer lifespan, is easier to maintain, and has strong compatibility.

[0076] Preferably, the positioning device can be a positioning pin, which can precisely control the position of the equipment and maintain the stability of the equipment in the target position. The positioning pin function also helps to improve the safety of the equipment. The positioning pin function can be adjusted and configured as needed to adapt to different position requirements.

[0077] In one embodiment, when the relay switch is turned on, the positioning point is slightly raised and higher than the printing platform; when the relay switch is turned off, the positioning point is slightly lower and lower than the printing platform.

[0078] Specifically, the positioning sensor detects the state of the relay switch and analyzes the relay switch. When the positioning sensor detects that the relay switch is on, the positioning sensor rises and needs to be higher than the printing platform.

[0079] The positioning pin detects the status of the relay switch and analyzes it. When the positioning pin detects that the relay switch is closed, the positioning pin will not be turned on, and the positioning pin will fall below the printing platform, ensuring that the positioning pin will not move even if the positioning pin switch is accidentally touched during the printing process.

[0080] In one embodiment, during the printing process, when the positioning device changes from off to on, the sensing sensor detects the change and immediately sends a second signal. The controller then controls the printing carriage to immediately stop the current printing job, thus ensuring that the print head and print head do not collide with the positioning device.

[0081] In one embodiment, when the printing carriage stops the current printing job, it stops at the current printing position. At this point, the system checks if the sensing signal is the second signal. If not, it indicates a sensor error causing the positioning device to activate, and the printing equipment issues an error alarm to notify the user of the sensor error. If yes, it indicates the sensor is not misinterpreting the data. Next, it checks if the preset control device is off. If it is not off, it indicates a preset control device error, and the printing equipment issues an error alarm to notify the user of the preset control device error. If the preset control device is off, but the positioning device is not off, it indicates a positioning device error, and the printing equipment issues an error alarm to notify the user of the positioning device error.

[0082] In summary, the printing equipment positioning device control method of this embodiment of the invention sets a sensing sensor at the zero point position of the printing equipment in the X motor direction. The sensing sensor detects whether the printing carriage is at the zero point position and controls the sensing sensor to send a sensing signal to the preset control device of the printing equipment. The control device and the positioning device are connected in series to achieve a linkage control effect. According to the sensing signal, the preset control device is controlled to open or close, and the positioning device is controlled to open or close simultaneously. When the printing carriage is at the zero point position in the X motor direction of the equipment, the preset control device and the positioning device are controlled to open; when the printing carriage is not at the zero point position in the X motor direction of the equipment, the preset control device and the positioning device are controlled to close. This ensures that the positioning device will not be activated due to accidental triggering during the printing operation of the printing carriage, thus ensuring the safety of the printhead during the printing process.

[0087] The switch control module 3 is used to control the preset control device to open or close simultaneously with the positioning device to open or close based on the sensing signal.

[0088] Preferably, the signal transmitting module 2 includes:

[0089] Signal control unit: used to send a first signal to the preset control device when the sensing sensor detects that the printing carriage is at the zero point position; used to send a second signal to the preset control device when the sensing sensor detects that the printing carriage is not at the zero point position.

[0091] Device control unit: When the sensing signal is a first signal, it controls the preset control device to turn on, and when the preset control device is turned on, the positioning device is turned on; when the sensing signal is a second signal, it controls the preset control device to turn off, and when the preset control device is turned off, the positioning device is turned off.

[0092] In this embodiment of the invention, the positioning device control device for the printing equipment uses a sensor located at the zero point position of the X-motor direction of the printing equipment. The sensor detects whether the printing carriage is at the zero point position and sends a signal to a preset control device of the printing equipment. This connects the control device and the positioning device in series for coordinated control. Based on the signal, the preset control device is turned on or off simultaneously with the positioning device. When the printing carriage is at the zero point position of the X-motor direction, both the preset control device and the positioning device are turned on; when the printing carriage is not at the zero point position, both are turned off. This ensures that the positioning device will not be accidentally activated during the printing process, thus ensuring the safety of the printhead.

[0102] In one embodiment, the positioning device includes:

[0103] The sensor device is located at the zero point in the X-axis direction of the device.

[0104] In this embodiment of the invention, the positioning device control device for the printing equipment uses a sensor located at the zero point position of the X-motor direction of the printing equipment. The sensor detects whether the printing carriage is at the zero point position and sends a signal to a preset control device of the printing equipment. This connects the control device and the positioning device in series for coordinated control. Based on the signal, the preset control device is turned on or off simultaneously with the positioning device. When the printing carriage is at the zero point position of the X-motor direction, both the preset control device and the positioning device are turned on; when the printing carriage is not at the zero point position, both are turned off. This ensures that the positioning device will not be accidentally activated during the printing process, thus ensuring the safety of the printhead.
