Description

Technical Field

[0001] The invention relates to the technical field of inkjet printers, and in particular to a camera stabilization movement method used for inkjet printer calibration. Background Art

[0002] Inkjet printer is a device that uses software control to mark products in a non-contact manner. It generally refers to continuous inkjet technology (Continuous Inkjet Printer), referred to as CIJ.

[0003] Since the inkjet printer needs to move quickly when working, the stability of the inkjet printer when moving determines the working efficiency and spraying accuracy of the inkjet printer. How to improve the stability of the inkjet printer when moving has become an urgent problem to be solved today. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a camera stable movement method used for inkjet printer calibration, which can not only move quickly when the inkjet printer is working, but also has good stability, high working efficiency and high spraying accuracy.

[0005] To achieve the above object, the present invention provides the following technical solutions: A camera stabilization movement method for inkjet printer calibration comprises the following steps: Check the balance of the linear motor; Detect the stability of the linear motor current; Compensate the current of the linear motor; Detect the vibration generated by the inkjet printer when it is working; Take corresponding shock-absorbing measures for the inkjet printer according to the magnitude of the vibration generated when the inkjet printer is working.

[0006] According to some embodiments of the present invention, the balance of the linear motor is detected by: S1. Install a level at the bottom of the linear motor; S2. If the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level; If the level meter shows that the linear motor is not in a horizontal state as a whole, it means that the level of the linear motor is not normal.

[0007] As a further solution of the present invention, when the linear motor is in a non-horizontal state as a whole, it is necessary to correct the horizontal state of the linear motor. The specific correction method is: S1. Install hydraulic cylinders at both ends of the linear motor. It should be noted that the two hydraulic cylinders are movably connected to the two ends of the linear motor respectively. S2, according to the horizontal state of the linear motor, the two hydraulic cylinders are respectively started to perform corresponding telescopic movements, so as to adjust the horizontal state of the linear motor; S3. When adjusting the horizontal state of the linear motor, the staff needs to observe the level meter at all times. When the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level.

[0008] According to some embodiments of the present invention, the detection of the stability of the linear motor current is specifically: S1. Use an ammeter to detect the current of the linear motor; S2, by measuring the voltage and resistance of the linear motor, using Ohm's law to detect the current of the linear motor; S3, detecting the current of the linear motor by using a current clamp; S4. The current values ​​of the linear motor obtained by the above three methods are averaged to obtain the final current value of the linear motor, referred to as A1.

[0009] According to some embodiments of the present invention, when the linear motor is working normally, the current of the linear motor is detected by an ammeter, and the detected current value is compared with A1. If the two values ​​are consistent, it indicates that the current of the linear motor is stable and the motion state of the linear motor is also stable; If the two values ​​are inconsistent, it means that the current of the linear motor is not stable, there is a sense of frustration in the movement of the linear motor, and the overall movement is not stable.

[0010] According to some embodiments of the present invention, the current of the linear motor is compensated by: S1, connect the adjustable resistor to the circuit of the linear motor; S2. If the current of the linear motor is small, the current of the linear motor can be adjusted by reasonably reducing the resistance value of the adjustable resistor until the current of the linear motor tends to A1; S3. If the current of the linear motor is large, the current of the linear motor can be adjusted by reasonably increasing the resistance value of the adjustable resistor until the current of the linear motor tends to A1.

[0011] According to some embodiments of the present invention, the vibration generated by the inkjet printer during operation is detected, specifically: S1. Routine inspection: When the printer is working normally, use a pen-type vibration meter to detect the vibration value of the working part of the printer, mainly the vibration speed. Measure the vibration speed in the axial, vertical and horizontal directions and record them as reference values. S2. Precision detection: Use a vibration spectrum analyzer to detect the vibration spectrum of the inkjet printer and analyze the vibration velocity components corresponding to each frequency. If the vibration velocity component of a certain frequency exceeds the limit, the fault point can be determined by comparing it with the common vibration fault identification table; Calculation of vibration frequency: The power frequency vibration frequency (Hz) of the operating part of the inkjet printer = speed (r / min) / 60. For example, if the speed of a fan is 960r / min, its power frequency vibration frequency is 16Hz. The power frequency vibration frequency is usually called the rotation frequency. S3. The vibration values ​​of the inkjet printer obtained by the above two methods are averaged and referred to as B1.

[0012] According to some embodiments of the present invention, when the inkjet printer is working normally, the vibration value of the inkjet printer is detected by using a pen test vibration meter. If the value of the pen test vibration meter is greater than B1, it indicates that the vibration of the inkjet printer is too large. If the value of the pen test vibration meter is less than or equal to B1, it indicates that the vibration of the inkjet printer is normal.

[0013] As a further solution of the present invention, if the vibration of the inkjet printer is too large, corresponding vibration reduction measures need to be taken on the inkjet printer.

[0014] Compared with the prior art, the camera stable movement method used in the inkjet printer calibration of the present invention has at least the following beneficial effects: The present invention adjusts the horizontality of the linear motor to make the level of the linear motor tend to be normal, so the level of the camera also tends to be normal, thereby improving the stability of the camera when working, and detects and compensates the current of the linear motor to make the current of the linear motor tend to be stable, so the operation of the linear motor also tends to be stable, further improving the stability of the camera when working, and detects and reduces the vibration of the inkjet printer to reduce the impact of the vibration of the inkjet printer when working on the stability of the camera, thereby further improving the stability of the camera when working. Compared with the existing ones, the present invention uses a camera to correct the inkjet printer. Since the camera has better stability when moving, the correction accuracy of the camera to the inkjet printer is also higher, which greatly improves the working efficiency and spraying accuracy of the inkjet printer.

[0020] As a further solution of the present invention, the step 1 is specifically: S1. Install a level at the bottom of the linear motor; S2. If the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level; If the level meter shows that the linear motor is not in a horizontal state as a whole, it means that the level of the linear motor is not normal.

[0021] When the linear motor is not in a horizontal state as a whole, it is necessary to correct the horizontal state of the linear motor. The specific correction method is: S1. Install hydraulic cylinders at both ends of the linear motor. It should be noted that the two hydraulic cylinders are movably connected to the two ends of the linear motor respectively. S2, according to the horizontal state of the linear motor, the two hydraulic cylinders are respectively started to perform corresponding telescopic movements, so as to adjust the horizontal state of the linear motor; S3. When adjusting the horizontal state of the linear motor, the staff needs to observe the level meter at all times. When the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level.

[0022] The specific steps of step 2 are: S1. Use an ammeter to detect the current of the linear motor; S2, by measuring the voltage and resistance of the linear motor, using Ohm's law to detect the current of the linear motor; S3, detecting the current of the linear motor by using a current clamp; S4. The current values ​​of the linear motor obtained by the above three methods are averaged to obtain the final current value of the linear motor, referred to as A1.

[0023] When the linear motor is working normally, the current of the linear motor is detected by an ammeter, and the detected current value is compared with A1. If the two values ​​are consistent, it indicates that the current of the linear motor is stable and the motion state of the linear motor is also stable; If the two values ​​are inconsistent, it means that the current of the linear motor is not stable, there is a sense of frustration in the movement of the linear motor, and the overall movement is not stable.

[0024] The specific steps of step three are: S1, connect the adjustable resistor to the circuit of the linear motor; S2. If the current of the linear motor is small, the current of the linear motor can be adjusted by reasonably reducing the resistance value of the adjustable resistor until the current of the linear motor tends to A1; S3. If the current of the linear motor is large, the current of the linear motor can be adjusted by reasonably increasing the resistance value of the adjustable resistor until the current of the linear motor tends to A1.

[0025] The specific steps of step 4 are: S1. Routine inspection: When the printer is working normally, use a pen-type vibration meter to detect the vibration value of the working part of the printer, mainly the vibration speed. Measure the vibration speed in the axial, vertical and horizontal directions and record them as reference values. S2. Precision detection: Use a vibration spectrum analyzer to detect the vibration spectrum of the inkjet printer and analyze the vibration velocity components corresponding to each frequency. If the vibration velocity component of a certain frequency exceeds the limit, the fault point can be determined by comparing it with the common vibration fault identification table; Calculation of vibration frequency: The power frequency vibration frequency (Hz) of the operating part of the inkjet printer = speed (r / min) / 60. For example, if the speed of a fan is 960r / min, its power frequency vibration frequency is 16Hz. The power frequency vibration frequency is usually called the rotation frequency. S3. The vibration values ​​of the inkjet printer obtained by the above two methods are averaged and referred to as B1.

[0026] When the printer is working normally, use a pen-test vibration meter to test the vibration value of the printer. If the value of the pen-test vibration meter is greater than B1, it indicates that the vibration of the printer is too large. If the value of the pen test vibration meter is less than or equal to B1, it indicates that the vibration of the inkjet printer is normal.

[0027] If the vibration of the inkjet printer is too large, corresponding vibration reduction measures need to be taken for the inkjet printer.

[0028] Specifically, the present invention adjusts the horizontality of the linear motor so that the level of the linear motor tends to be normal, so the level of the camera also tends to be normal, thereby improving the stability of the camera when it is working, and detects and compensates the current of the linear motor so that the current of the linear motor tends to be stable, so the operation of the linear motor also tends to be stable, further improving the stability of the camera when it is working, and detects and reduces the vibration of the inkjet printer to reduce the impact of the vibration of the inkjet printer when it is working on the stability of the camera, thereby further improving the stability of the camera when it is working. Compared with the existing ones, the present invention uses a camera to correct the inkjet printer. Since the camera has better stability when moving, the correction accuracy of the camera to the inkjet printer is also higher, which greatly improves the working efficiency and spraying accuracy of the inkjet printer.

[0029] Working principle: First, mount the camera onto the linear motor; Install a level at the bottom of the linear motor; If the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level; If the level meter shows that the linear motor is not in a horizontal state as a whole, it means that the level of the linear motor is not normal.

[0030] When the linear motor is not in a horizontal state as a whole, it is necessary to correct the horizontal state of the linear motor. The specific correction method is: Hydraulic cylinders are installed at both ends of the linear motor. It should be noted that the two hydraulic cylinders are movably connected to the two ends of the linear motor respectively. According to the horizontal state of the linear motor, two hydraulic cylinders are respectively started to perform corresponding telescopic movements, so as to adjust the horizontal state of the linear motor; When adjusting the level of the linear motor, the staff needs to observe the level meter at all times. When the level meter shows that the linear motor is in a horizontal state as a whole, it means that the linear motor is in a normal level. Secondly, the current of the linear motor is detected using an ammeter; By measuring the voltage and resistance of the linear motor, the current of the linear motor is detected using Ohm's law; Use current clamp to detect the current of linear motor; The current values ​​of the linear motor obtained by the above three methods are averaged to obtain the final current value of the linear motor, referred to as A1.

[0031] When the linear motor is working normally, the current of the linear motor is detected by an ammeter, and the detected current value is compared with A1. If the two values ​​are consistent, it indicates that the current of the linear motor is stable and the motion state of the linear motor is also stable; If the two values ​​are inconsistent, it means that the current of the linear motor is not stable, there is a sense of frustration in the movement of the linear motor, and the overall movement is not stable.

[0032] Connect the adjustable resistor to the circuit of the linear motor; If the current of the linear motor is small, the current of the linear motor can be adjusted by reasonably reducing the resistance value of the adjustable resistor until the current of the linear motor tends to A1; If the current of the linear motor is large, the current of the linear motor can be adjusted by reasonably increasing the resistance value of the adjustable resistor until the current of the linear motor tends to A1; Finally, for routine testing, when the printer is working normally, use a pen-type vibration meter to detect the vibration value of the working part of the printer, mainly the vibration speed, measure the vibration speed in the axial, vertical and horizontal directions and record them as reference values; Precision detection: Use a vibration spectrum analyzer to detect the vibration spectrum of the printer and analyze the vibration velocity components corresponding to each frequency. If the vibration velocity component of a certain frequency exceeds the limit, the fault point can be determined by comparing it with the common vibration fault identification table; Calculation of vibration frequency: The power frequency vibration frequency (Hz) of the operating part of the inkjet printer = speed (r / min) / 60. For example, if the speed of a fan is 960r / min, its power frequency vibration frequency is 16Hz. The power frequency vibration frequency is usually called the rotation frequency. The vibration values ​​of the printer obtained by the above two methods are averaged and referred to as B1.

[0033] When the printer is working normally, use a pen-test vibration meter to test the vibration value of the printer. If the value of the pen-test vibration meter is greater than B1, it indicates that the vibration of the printer is too large. If the value of the pen test vibration meter is less than or equal to B1, it indicates that the vibration of the inkjet printer is normal.

[0034] If the vibration of the inkjet printer is too large, corresponding vibration reduction measures need to be taken for the inkjet printer.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
