Description

Technical Field

[0001] This utility model relates to the field of display module circuit technology, specifically to a display module circuit for a sealing machine. Background Technology

[0002] In sealing machines, the display module circuit plays a crucial role. It is responsible for presenting the sealing machine's working status, parameter settings, and other information to the user through the display device, while also receiving the user's key operation commands to realize human-machine interaction.

[0003] Currently, existing sealing machine display module circuits on the market have several shortcomings. First, the circuit structure is complex, with cumbersome connections between various functional modules, leading to lengthy production and installation processes and increased difficulty in subsequent maintenance, thus raising production and maintenance costs. Second, some display module circuits suffer from poor driving stability, easily exhibiting problems such as LED flickering, uneven brightness, and even display errors during use, affecting users' accurate judgment of the sealing machine's operating status. Third, the button drive response is not sensitive enough; after a user presses a button, the circuit cannot promptly respond and execute the corresponding command, reducing operational convenience. Furthermore, communication between the power board and various modules is unstable, easily affected by external interference, leading to data transmission errors and impacting the normal operation of the entire display module. Finally, the buzzer, as an alarm device, is unstable in some existing circuits, sometimes failing to emit an alarm sound in time, unable to promptly alert users to abnormal situations in the sealing machine, posing a certain safety hazard.

[0004] Therefore, developing a sealing machine display module circuit that is simple in structure, stable in drive, sensitive in button response, reliable in communication, and timely in alarm is of great practical significance. Utility Model Content

[0031] The button driver module includes switches SW1, SW2, SW3, SW4, SW5, and SW6. One end of switch SW1 is connected to pin SEG5, and the other end of switch SW1 is connected to one end of resistor R1, which is connected to pin COM1.

[0033] The VCC pin of the LED driver module is connected to two capacitors C1 and C2 connected in parallel. The model of the chip IC1 is TM1650.

[0034] Working principle:

[0035] Power Supply Process: The 5V power supply enters the power board communication module through pin 2 of chip CN1, providing the operating voltage for the entire circuit. Pin 1 of chip CN1 is grounded to ensure the zero-potential reference point of the circuit. The VCC pin of the LED driver module receives the 5V voltage. At the same time, the parallel capacitors C1 and C2 connected to the VCC pin filter the power supply voltage, removing noise and ensuring a stable operating voltage for chip IC1.

[0036] Communication Process: Data transmission between the power board and the display module occurs via the power board communication module. Pin 3 of chip CN1 is connected to the DAT pin of chip IC1 via resistor R7, and pin 4 is connected to the CLK pin of chip IC1 via resistor R8. The DAT pin is the data transmission pin, and the CLK pin is the clock signal pin. Under the synchronization of the clock signal, data is transmitted bidirectionally through the DAT pin. Resistors R7 and R8 limit the current during transmission, protecting the relevant pins and ensuring communication stability.

[0037] LED Display Process: The LED driver module's IC1 chip controls the LED display module's operation through SEG1-SEG8 pins and COM1-COM4 pins. When IC1 needs to control a specific LED to light up, it outputs a high level through the corresponding SEG pin and simultaneously controls the COM pin connected to the negative terminal of that LED to output a low level, creating a potential difference across the LED and allowing current to flow through it, thus lighting it up. For example, when LED1 needs to be lit, IC1 controls the SEG5 pin to output a high level and the COM2 pin to output a low level. Current flows from the SEG5 pin through LED1 to the COM2 pin, lighting up LED1. By controlling different combinations of SEG and COM pin levels, different LEDs can be turned on and off, thereby presenting various display information.

[0038] Button driving process: When a user presses a switch in the button driving module, the corresponding circuit is activated. Taking switch SW1 as an example, when SW1 is pressed, the SEG5 pin is connected to the COM1 pin through SW1 and resistor R1. Chip IC1 detects the level change between the SEG5 and COM1 pins, identifies that SW1 is pressed, and then executes the operation corresponding to that button. Resistors R1-R6 limit current to prevent excessive current from damaging the pins of chip IC1.

[0039] Buzzer Alarm Process: When the power board detects an abnormality in the sealing machine through the power board communication module, it outputs a control signal through pin 5 of chip CN1. This signal is filtered by capacitor C5 and then transmitted to the buzzer BUZ, energizing the buzzer BUZ to emit an alarm sound, alerting the user to the equipment malfunction and requiring immediate attention. Capacitor C5 filters out noise in the signal, ensuring stable buzzer operation.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
