Technical Field

[0001] This invention relates to the field of mobile phone case printing technology, and more specifically, to a method, device, and storage medium for automatic alignment of consumables for mobile phone case printers. Background Technology

[0002] With the rapid development of mobile communication technology, mobile phones have become an indispensable part of people's daily lives. The demand for mobile phone cases, closely related to mobile phones, has also surged. This industry has formed a large and dynamic market with continuously rising annual sales. Consumer aesthetics are constantly changing, and personalized customization has become a new trend in the mobile phone case industry, leading to a growing demand for self-service and shared mobile phone case printing services. However, current mobile phone case printers suffer from many inconveniences in actual operation. Traditional models are mostly modified from universal printers. When printing different brands and models of mobile phone cases, due to their varying shapes and sizes, each replacement of consumables requires manual intervention for tedious alignment operations. Operators need to spend time and energy accurately setting the printing starting point and fixing the consumables one by one. This entire process is not only inefficient but also prone to errors. In the current pursuit of automation and intelligence, this over-reliance on manual operation not only incurs high labor costs but also fails to meet the convenience requirements of self-service printing in the sharing economy era. This greatly limits the application and promotion of mobile phone case printers in a wider range of scenarios, becoming a development bottleneck that the industry urgently needs to overcome.

[0003] Existing mobile phone case printers require cumbersome manual alignment, are inefficient, and are difficult to adapt to the needs of unattended self-service printing. Summary of the Invention

[0004] In order to overcome the problems of cumbersome manual alignment, low efficiency, and difficulty in adapting to the needs of unattended self-service printing in existing mobile phone case printers, this invention discloses an automatic alignment method, device and storage medium for mobile phone case printer consumables that can effectively solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: An automatic alignment method for mobile phone case printer consumables includes the following steps: A dynamic positioning system is established by using an L-shaped push plate component and an electronically controlled magnetic suction device on the printing platform. When the printer carriage assembly is detected to have fallen into the printing platform, it is controlled to move laterally until the alignment sensor triggers the magnetic linkage. The consumables are pushed to the platform reference boundary through the coordinated action of the X / Y axis push plate mechanism; Dynamically calculate the size and placement direction of consumables based on the displacement data of the X / Y axis push plate mechanism; Automatically adjust printing coordinate parameters based on direction determination results; After positioning is completed, control the push plate mechanism to reset to the initial position.

[0006] Preferably, the magnetic attraction linkage includes: When the first alignment sensor on the printer carriage assembly is optically aligned with the second alignment sensor on the L-shaped push plate component; Control the electromagnet to generate magnetic attraction force; Establish the mechanical linkage between the printer carriage assembly and the L-shaped push plate component.

[0007] Preferably, the dimensions of the dynamic computing consumables include: Record the number of motor steps when the X-axis push plate mechanism triggers the positioner; Calculate the actual length in the Y-axis direction based on the correspondence between the number of steps and the unit step size; The calculation results are then matched against a pre-stored model database to determine the pattern. When the detected length difference exceeds the threshold, it is determined to be an abnormal placement state.

[0008] Preferably, the direction determination includes: Establish the mapping relationship between the stroke of the X / Y axis push plate mechanism and the dimensions of the standard model; A horizontal placement identifier is generated when the stroke value of the Y-axis push plate mechanism meets the horizontal placement characteristic value. When the travel value of the X-axis push plate mechanism exceeds the vertical placement threshold range, a secondary verification process is triggered.

[0009] Preferably, adjusting the printing coordinate parameters includes: Select the corresponding image transformation matrix based on the direction determination result; Print the starting coordinates ( Dynamically corrected to ( , ); Where Δx and Δy are position compensation values ​​calculated based on the consumable contour features.

[0010] Preferably, it also includes an exception handling mechanism: When the positioning sensor is not triggered after three consecutive push plate actions; Start the platform vibration device to fine-tune the position of consumables; Activate the auxiliary visual positioning system to attempt a second positioning.

[0011] Preferably, the reset operation includes: Move the push plate mechanism back to the initial coordinates along the X / Y axis in the opposite direction; Keep the magnetic attraction device disconnected during movement; After the reset is complete, a ready signal is sent to the main control system.

[0012] Preferably, an electronic device includes: The printing platform module integrates an L-shaped push plate component with magnetic attraction function; A multi-axis positioning system, comprising an X / Y axis push plate mechanism and a displacement sensor array; The intelligent control module is configured to execute the steps of the alignment method described above; The dynamic compensation module is used to adjust the printing coordinate parameters in real time.

[0014] A computer-readable storage medium storing program instructions that, when executed by a processor, implement the steps of the alignment method as described above.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention solves the problems of tedious manual alignment, low efficiency, and difficulty in adapting to unattended self-service printing in existing mobile phone case printers. Firstly, because the consumables have different shapes, printers require manual setting of the printing starting point and fixing of the consumables, which is complex and labor-intensive. This invention constructs a dynamic positioning system through an L-shaped push plate component and an electrically controlled magnetic suction device on the printing platform. When the consumable falls into the platform, the printer carriage component moves laterally until the alignment sensor triggers the magnetic suction linkage, realizing automatic grabbing and preliminary positioning of the consumable, eliminating the step of manual intervention and laying the foundation for accurate positioning. Secondly, previous printers could not automatically identify the size and placement direction of the consumables, requiring repeated manual adjustments to ensure the correctness of the printed pattern. However, this invention utilizes the coordinated action of the X / Y axis push plate mechanism to push the consumables to the platform reference boundary, and dynamically calculates the size and placement direction of the consumables based on the displacement data of the push plate mechanism. The system automatically adjusts printing coordinate parameters based on the direction determination result, achieving precise positioning of consumables and adaptive adjustment of printing parameters, thus improving printing efficiency and accuracy and meeting the needs of self-service printing scenarios. Furthermore, traditional equipment is prone to jamming or errors when consumables are misplaced, affecting the printing process. This invention also includes an anomaly handling mechanism: if the positioning sensor is not triggered by three consecutive push-plate actions, the platform vibration device is activated to fine-tune the consumable position, and the auxiliary visual positioning system is activated for a second positioning attempt, enhancing the system's fault tolerance and stability. Finally, after completing positioning, the invention controls the push-plate mechanism to reset to its initial position, preparing for the next printing task, further improving printing continuity and automation. Through these improvements, this invention not only reduces labor costs but also improves printing efficiency and system stability, successfully solving the application challenges of existing mobile phone case printers in self-service printing scenarios.

[0020] An automatic alignment method for mobile phone case printer consumables includes the following steps: A dynamic positioning system is established by using an L-shaped push plate component and an electronically controlled magnetic suction device on the printing platform.

[0026] The reset operation includes: Move the push plate mechanism back to the initial coordinates along the X / Y axis in the opposite direction; Keep the magnetic attraction device disconnected during movement; After the reset is complete, a ready signal is sent to the main control system.

[0027] An electronic device, comprising: The printing platform module integrates an L-shaped push plate component with magnetic attraction function; A multi-axis positioning system, comprising an X / Y axis push plate mechanism and a displacement sensor array; The intelligent control module is configured to execute the steps of the alignment method described above; The dynamic compensation module is used to adjust the printing coordinate parameters in real time.

[0028] The L-shaped push plate component includes: A right-angle guiding structure composed of a non-magnetic substrate; Replaceable magnetic inserts embedded on the inside; A distributed array of infrared beam sensors.

[0029] A computer-readable storage medium storing program instructions that, when executed by a processor, implement the steps of the alignment method as described above.

[0030] For specific implementation details, please refer to [link / reference]. Figure 1-3 The printing platform used in this embodiment integrates a specially designed L-shaped push plate component on its surface. The L-shaped push plate component is composed of a right-angle guiding structure made of a non-magnetic substrate. This structure is robust and durable and can effectively avoid interference with the magnetic field, ensuring the accuracy of the magnetic attraction operation. On the inner side of the L-shaped push plate component, there are replaceable magnetic inserts. These inserts are made of metal materials that can be attracted by magnets, which facilitates their use with electrically controlled electromagnets. At the same time, infrared photoelectric sensor groups are distributed on the L-shaped push plate component as the second alignment sensor B, which works in conjunction with the first alignment sensor A on the printer carriage assembly to achieve precise alignment. X-axis positioner x2 and Y-axis positioner x1 are installed in the lower right corner of the printing platform. Both of these positioners are high-precision displacement sensors that can accurately detect the position information of the push plate mechanism pushing the consumable to the platform reference boundary and transmit the signal to the printer motherboard in real time.

[0031] The printer carriage assembly is a key moving component of the entire printing system. An electrically controlled electromagnet is installed on the metal edge of the carriage assembly. The electromagnet is controlled by the printer motherboard to turn on and off. At the same time, the carriage assembly is also equipped with a first alignment sensor A, which works in conjunction with a second alignment sensor B on the L-shaped push plate. When the two are optically aligned, a magnetic linkage mechanism is triggered.

[0032] The multi-axis positioning system includes an X-axis pusher mechanism Xp and a Y-axis pusher mechanism Yp, which are responsible for pushing the consumables in the X and Y axes, respectively. Both pusher mechanisms are driven by high-precision motors, and the number of motor steps can be accurately recorded to calculate the size of the consumables. A displacement sensor array is also installed on the pusher mechanism to monitor the displacement of the pusher mechanism in real time, ensuring the accuracy and stability of the pusher action.

[0033] The intelligent control module is the core control unit of the entire printer. It is configured to execute each step of the automatic alignment method for the phone case printer filaments. This module receives signals from various sensors, including X-axis or Y-axis sensors, alignment sensors A and B, and positioners x1 and x2. It analyzes and processes these signals according to preset program logic, controlling the actions of the printer carriage assembly, push plate mechanism, and electrically controlled electromagnet. The dynamic compensation module is used to adjust the printing coordinate parameters in real time. Based on the filament placement direction and position information calculated by the intelligent control module, it selects the corresponding image transformation matrix and sets the printing start point coordinates (…). Dynamically corrected to ( , ), where Δx and Δy are position compensation values ​​calculated based on the contour features of the consumable material, ensuring that the printed image can be accurately printed on the phone case.

[0034] In actual operation, the phone case falls from the conveyor onto the printing platform. Since the phone case may have various positional deviations during the conveying process, its initial position is arbitrary. When the phone case falls onto the printing platform, it triggers the sensor installed on the printing platform. The sensor sends a signal to the intelligent control module. After receiving the signal, the intelligent control module determines that the printing task has started and initiates the subsequent automatic alignment process.

[0035] After receiving the print start signal, the intelligent control module controls the printer carriage assembly to move from the right ink station to the left. During the movement, the first alignment sensor A installed on the carriage assembly and the second alignment sensor B on the L-shaped push plate continuously work. When the first alignment sensor A and the second alignment sensor B form optical alignment, both sensors simultaneously send a trigger signal to the intelligent control module. After receiving the trigger signal, the intelligent control module immediately controls the electromagnet to be energized. At this time, the magnet generates a magnetic attraction force, attracting the replaceable magnetic insert on the L-shaped push plate, thereby establishing a mechanical linkage between the printer carriage assembly and the L-shaped push plate.

[0036] After establishing the mechanical linkage, the printer carriage assembly begins to push back to the right. The L-shaped pusher plate, linked to the carriage assembly, drives the X-axis pusher mechanism Xp to move to the right, pushing the filament towards the right edge of the printing platform. When the filament is pushed to the right edge of the printing platform, it creates resistance with the pusher plate, triggering the X-axis positioner x2. The X-axis positioner x2 sends a trigger signal to the intelligent control module. Upon receiving the signal, the intelligent control module immediately stops the X-axis motor. Simultaneously, the intelligent control module records the number of steps taken by the X-axis pusher mechanism Xp motor. Based on the pre-set correspondence between the number of steps and the unit step length, the intelligent control module calculates the actual length of the filament in the Y-axis direction. For example, assuming each step of the motor corresponds to a distance of 0.1mm, and the recorded number of steps is 500, then the calculated actual length in the Y-axis direction is 50mm. Subsequently, the intelligent control module performs pattern matching between the calculated actual length in the Y-axis direction and a pre-stored model database, which stores various common mobile phone models. The corresponding standard size information of the phone case is used. When the difference between the calculated length and the standard size exceeds a preset threshold, such as ±5mm, the intelligent control module determines that the phone case is in an abnormal placement state. After completing the push-plate action in the X-axis direction, the intelligent control module controls the Y-axis push-plate mechanism Yp to perform a top-down push-plate action. The working principle of the Y-axis push-plate mechanism Yp is similar to that of the X-axis push-plate mechanism XP. When the consumable is pushed to trigger the Y-axis positioner x1, the Y-axis positioner x1 sends a trigger signal to the intelligent control module. The intelligent control module controls the Y-axis motor to stop rotating and records the number of steps of the Y-axis push-plate mechanism Yp motor at this time, in preparation for calculation and direction determination.

[0037] The intelligent control module calculates the actual dimensions of the consumable in the X and Y axes based on the recorded step counts of the X and Y axis pusher mechanism motors and their corresponding unit step lengths. Simultaneously, by establishing a mapping relationship between the X / Y axis pusher mechanism travel and standard phone case dimensions, the intelligent control module determines the phone case's placement orientation. For example, in a pre-stored phone case database, the standard Y-axis length range for a common phone case is 60-70mm when placed horizontally, and 140-150mm when placed vertically. When the Y-axis pusher mechanism travel value (Yp) calculated by the intelligent control module matches the horizontal placement characteristic value (e.g., the calculated actual Y-axis length is 65mm), the intelligent control module generates a horizontal placement identifier. When the X-axis pusher mechanism travel value (Xp) exceeds the vertical placement threshold, to avoid misjudgment, the intelligent control module triggers a secondary verification process. This secondary verification process may include re-detecting the X / Y axis pusher mechanism travel data and comparing it with other relevant sensor data, such as image data obtained through an auxiliary vision positioning system, to ensure the accuracy of the placement orientation determination.

[0038] The intelligent control module selects the corresponding image transformation matrix based on the placement orientation. If the phone case is determined to be horizontal, an image transformation matrix suitable for horizontal printing is selected; if it is determined to be vertical, the image transformation matrix corresponding to vertical printing is selected. Simultaneously, the dynamic compensation module calculates position compensation values ​​Δx and Δy based on the material's contour features. For example, by detecting the edge position of the phone case, which can be obtained by an auxiliary vision positioning system or other sensors, analysis is performed to determine the actual positional deviation of the phone case on the printing platform, thereby calculating appropriate Δx and Δy values. Then, the dynamic compensation module adjusts the printing start point coordinates (…). Dynamically corrected to ( , This ensures that the printed image accurately fits the position and orientation of the phone case.

[0039] After the phone case is positioned and the printing coordinate parameters are adjusted, the intelligent control module controls the push plate mechanism to reset to its initial position. The push plate mechanism moves in the opposite direction along the X / Y axis. During the movement, the intelligent control module controls the electromagnet to disconnect, causing the L-shaped push plate to separate from the printer carriage assembly. When the push plate mechanism moves to the initial coordinate position, the sensor installed on the push plate mechanism sends a reset completion signal to the intelligent control module. After receiving the signal, the intelligent control module sends a ready signal to the main control system, informing the main control system that the phone case has been positioned and the printer can start the printing task.

[0040] During actual operation, various abnormal situations may occur. If the positioning sensor is not triggered by three consecutive push-plate actions, it indicates that the consumable may be in a state of serious deviation from the expected position. Ordinary push-plate operations cannot accurately push it to the platform reference boundary. At this time, the intelligent control module activates the platform vibration device to fine-tune the position of the consumable, such as an electromagnetic vibrator. The platform vibration device generates vibrations of a certain frequency and amplitude, causing the phone case on the printing platform to change position under the vibration, which may move it to a position that can be smoothly pushed by the push-plate mechanism. At the same time as activating the platform vibration device, the intelligent control module activates the auxiliary visual positioning system to make a secondary positioning attempt. The auxiliary visual positioning system is usually composed of a camera and an image recognition algorithm. The camera captures an image of the phone case on the printing platform, and the image recognition algorithm analyzes the image to determine the accurate position and shape information of the phone case. Based on the data provided by the auxiliary visual positioning system, the intelligent control module replans the action of the push-plate mechanism and tries to position the phone case again to ensure that the printing task can be carried out smoothly.
