Detailed Description
Generally, the force for pushing the print head is different for different installation modes of the print head, so that a user needs to set the working current of the electromagnet of the thermal transfer printer according to different installation modes of the print head, and the intelligentization is low. Therefore, the technical scheme provided by the embodiment of the application can adaptively adjust the working current of the electromagnet according to different installation modes of the printing head of the thermal transfer printer, so that the printing head is driven by the electromagnet to move, the adaptive adjustment of the working force required by different installation modes is realized, the independent setting of a user is not needed, and the intellectualization of the thermal transfer printer is improved.
The working force refers to a force required for the print head to complete a printing task, and may include a force (which may be referred to as an "urging force" herein) for urging the print head to a printing position against a resistance of the print head returning mechanism, and a force (which may be referred to as a "printing pressure" herein) continuously applied between the print head and the printing medium. The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Fig. 1 is a schematic flowchart of a method for controlling a print head driving assembly of a thermal transfer printer according to an embodiment of the present disclosure. The present embodiment relates to a situation of adaptive adjustment of a working force required by a thermal transfer printer, where the method may be executed by a controller of the thermal transfer printer in the embodiment of the present application, the thermal transfer printer further includes a print head, an electromagnet, and a displacement monitoring module, the electromagnet is configured to drive the print head to move toward a printing position, the displacement monitoring module is configured to monitor a displacement of the print head, and optionally, the displacement monitoring module may be a hall displacement sensor or a grating ruler displacement sensor. As shown in fig. 1, the method may include:
and S101, determining a basic current value.
And the basic current value is a current value required by the electromagnet to drive the printing head to move to the printing position.
In the embodiment, the working force of the thermal transfer printer is provided by the electromagnet, namely, the printing head is driven to work by the attraction force of the electromagnet, so that the printing task is completed. Alternatively, the print head of the thermal transfer printer may be installed towards the ground (i.e. installed upright), or installed away from the ground (i.e. installed upside down), or installed side-ways or obliquely, and the working force of the print head required by different installation modes of the print head is different, for example, the working force required by the print head for installing upside down is larger than that required by installing upright. That is, the force with which the printhead is urged against the resistance of the printhead return mechanism to the print position is not the same for different mounting configurations of the printhead.
Generally, the attractive force output by the electromagnet is controlled by current, so that in order to realize the required driving force under different installation modes of the printing head, the basic current value required for driving the printing head to move to the printing position by the electromagnet of the thermal transfer printer can be obtained by sequentially adjusting the current of the electromagnet, so that the corresponding basic current value can be obtained no matter the printing head of the thermal transfer printer is installed in a forward mode, a reverse mode, a side mode or an inclined mode, the basic current value is used for controlling the electromagnet in the thermal transfer printer to drive the printing head to move, and the printing head can be moved to the printing position.
And S102, determining a current compensation value.
Wherein the current compensation value is a current value required by the electromagnet to drive the printing head to generate printing pressure at the printing position. The basic current value enables the electromagnet to drive the printing head to move to the printing position, and the printing head needs to output a certain printing pressure when the printing head completes a printing task, namely, the current compensation value is a current value for providing the printing pressure for the printing head. Optionally, the process of determining the current compensation value may be: acquiring a distance between a mounting position and a printing position of a printing head and a desired printing pressure; and determining a current compensation value corresponding to the expected printing pressure according to the working characteristic curve of the electromagnet at the distance.
Specifically, the desired printing pressure refers to a printing pressure of a print head output desired to complete a print job, and may be set in advance based on a printing demand in general. In practical application, different distances correspond to different working characteristic curves, so that the distance between the installation position and the printing position of the printing head of the thermal transfer printer can be obtained, then the working characteristic curve of the electromagnet corresponding to the distance is determined, the working characteristic curve comprises the corresponding relation between the printing pressure and the current value, and therefore the current compensation value corresponding to the expected printing pressure can be determined through the working characteristic curve.
S103, determining a target current value according to the basic current value and the current compensation value, and controlling the electromagnet to work based on the target current value.
After obtaining the basic current value and the current compensation value, the thermal transfer printer controller controls the electromagnet to work according to the basic current value and the current compensation value. Alternatively, the current compensation value may be superimposed on the base current value, that is, the sum of the base current value and the current compensation value is determined as a target current value, and the electromagnet is controlled to operate based on the target current value, so that the electromagnet can generate the working force required by the print head to drive the print head to move, thereby completing the printing task. Therefore, no matter the printing head of the thermal transfer printer is positively installed, reversely installed, laterally installed or obliquely installed, the working force required by the printing head under the corresponding installation mode can be achieved, and the self-adaptive adjustment of the working force of the printing head under different printing head installation modes is realized.
The method for controlling the printing head driving assembly of the thermal transfer printer determines a basic current value required by the electromagnet to drive the printing head to move to the printing position, determines a current compensation value required by the electromagnet to drive the printing head to generate printing pressure at the printing position, further determines a target current value according to the basic current value and the current compensation value, and controls the electromagnet to work based on the target current value, so that the force for pushing the printing head to move converted from the target current value can meet the printing requirement, the printing quality is improved, the abrasion of the printing head is reduced, and the service life of the printing head is prolonged. In addition, according to the technical scheme, under any printing head installation mode, a proper target current value can be configured for the electromagnet, so that the printing requirement under the current installation mode is met, a user does not need to separately set different installation modes, and the thermal transfer printer is more intelligent.
In one embodiment, a smaller current may be set for the electromagnets and the base current value may be obtained by sequentially increasing the current to the electromagnets. Therefore, on the basis of the above embodiment, optionally, as shown in fig. 2, the process of S101 may be:
s201, controlling the electromagnet to drive the printing head to move according to a first current value, and obtaining a first displacement of the printing head corresponding to the first current value.
Specifically, the thermal transfer printer can obtain the basic current value of the control electromagnet through a plurality of circulation processes. During the first cycle, the first current value may be an initial current value set for the electromagnet in advance, and generally, the first current value may be set to be smaller, so that the base current value of the electromagnet is obtained by sequentially increasing the first current value. The first current value may be a second current value set for the electromagnet during a previous cycle, during a non-initial cycle.
Alternatively, a displacement monitoring module is provided in the thermal transfer printer, and the displacement monitoring module may be provided on the print head, and the displacement of the print head moving toward the printing position is acquired by the displacement monitoring module. Optionally, the displacement monitoring module may be a hall displacement sensor or the like, or may be a grating ruler displacement sensor, and the specific type of the displacement monitoring module is not limited in this embodiment. It can be understood that when the printing head of the thermal transfer printer is installed normally, the pressing displacement of the printing head can be obtained through the displacement monitoring module, when the printing head of the thermal transfer printer is installed reversely, the ascending displacement of the printing head can be obtained through the displacement monitoring module, and by analogy, the displacement of the printing head moving towards the printing position can be obtained through the displacement monitoring module.
S202, increasing the first current value to obtain a second current value, and controlling the electromagnet to drive the printing head to move according to the second current value to obtain second displacement of the printing head.
The first current value may be increased according to a certain rule, for example, according to a preset increment. Alternatively, there may be a plurality of preset increments, and initially, a larger preset increment may be selected to increase the first current value, and as the number of times of sequential increases changes, a smaller preset increment may be selected to increase the first current value.
After the second current value is obtained, the electromagnet can be controlled again to drive the printing head to move towards the printing position directly based on the second current value, and the second displacement of the printing head moving towards the printing position is obtained through the displacement monitoring module.
S203, determining a basic current value based on the difference value of the first displacement and the second displacement.
After acquiring the first displacement and the second displacement, a controller of the thermal transfer printer may determine a base current value for controlling the electromagnets by comparing magnitudes between the first displacement and the second displacement and based on the comparison result.
In one embodiment, optionally, if a difference between the first displacement and the second displacement is less than or equal to a preset threshold, determining the first current value as the base current value;
and if the difference value between the first displacement and the second displacement is larger than a preset threshold value, taking the second current value as a new first current value, taking the second displacement as a new first displacement, obtaining the first displacement and the second displacement again until the difference value between the first displacement and the second displacement is smaller than or equal to the preset threshold value, and determining the latest first current value as a basic current value.
Specifically, the preset threshold may be set in combination with practical experience. In the case where the difference between the first displacement and the second displacement is less than or equal to the preset threshold value, it is indicated that the driving force of the electromagnet converted by the first current value and the second current value is equivalent, and the driving force converted by the second current value has failed to cause the print head to continue moving toward the printing position, at which point it can be determined that the print head has contacted the print medium, the first current value can be determined as the basic current value for controlling the electromagnet.
When the difference between the first displacement and the second displacement is larger than the preset threshold, it indicates that the printing head still moves a certain distance towards the printing position after the current value is increased, the driving force of the electromagnet converted by the first current value cannot move the printing head to the printing position, but at this time, it cannot be determined whether the driving force of the electromagnet converted by the second current value moves the printing head to the printing position, and the next round of circulation process is needed to confirm. Therefore, the second current value may be taken as a new first current value, the second displacement may be taken as a new first displacement, the first displacement and the second displacement may be reacquired, it may be determined again whether a difference between the reacquired first displacement and the second displacement is less than or equal to the preset threshold, and if so, the latest first current value may be determined as the base current value. If the difference value between the second displacement and the first displacement is still larger than the preset threshold value, the driving force of the electromagnet converted by the latest first current value still cannot move the printing head to the printing position, and a next circulation process is needed to search the basic current value of the electromagnet capable of moving the printing head to the printing position.
In this embodiment, the thermal transfer printer can be through the electric current that increases the electro-magnet in proper order, and the current value control electro-magnet drive after increasing beats printer head and removes, obtain the displacement of beating printer head, change through the size between this displacement and the last displacement, confirm to make and beat printer head and remove to the basic current value of the electro-magnet of printing the position, and combine the electro-magnet work of current compensation value and basic current value control thermal transfer printer, thereby satisfy the printing demand, need not to distinguish the mounting means that the thermal transfer printer beaten printer head at this in-process, the control current that all can satisfy the printing demand for thermal transfer printer automatic determination, need not the user to beat printer head mounting means to the difference and carry out the independent setting of electro-magnet control current, the convenience and the suitability of thermal transfer printer installation have been improved, reduce installation training cost and after sale cost.
