Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a detection circuit for an anti-static lamp and a printing equipment. Background Art

[0002] The cleaning lamp, a core component of the drum assembly in printers and copiers, plays a crucial role. Its function is to remove residual charge from the drum surface, paving the way for subsequent printing. If the cleaning lamp malfunctions, printed paper may exhibit residual image or background dust, affecting print quality.

[0003] To produce compatible drum assemblies, manufacturers commonly adopt strategies such as recycling the discharge lamps from used original drum assemblies or using aftermarket LED lamps to produce their own discharge lamps. However, these manufacturers often fall short in testing the discharge lamps, tending to rely solely on the ability to illuminate after powering on as the basis for installation, while overlooking the more critical step of testing.

[0004] In reality, proper operation of the cleaning lamp requires more than just power. To ensure complete removal of electrical charges from the photosensitive drum surface, the light emitted by the lamp at a specific voltage must meet the required wavelength intensity. Unfortunately, this wavelength intensity is difficult to determine visually.

[0005] Although there are mature spectral detection equipment on the market that can accurately analyze the wavelength intensity of light sources, such equipment is generally expensive and has a slow detection speed. Therefore, it is more often used as an auxiliary tool for parameter detection rather than a direct detection method on the production line. Utility Model Content

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] The definitions of various nouns or methods in the following embodiments, except for those that are logically untenable, are generally based on the broad concepts that can be implemented under the premise of the disclosure in the embodiments. Under such an understanding, the various specific subordinate specific definitions of the nouns or methods should be regarded as the utility model content of the utility model, and should not be narrowly understood or biasedly interpreted on the grounds that the specification does not disclose such specific definitions. Similarly, under the premise that it can be logically implemented, the order of the steps in the method is flexible and changeable, and the specific subordinate specific definitions of the broad concepts of various nouns or methods are all within the scope of protection of the utility model.

[0042] The main solution of the embodiment of the present application is: by providing an extinction lamp and a spectrum detection circuit, and the spectrum detection circuit includes a spectrum sensor, and the spectrum sensor is arranged at the light source of the extinction lamp, so that the spectrum detection circuit is used to receive the light source of the extinction lamp to detect the intensity of each wavelength of the light source, thereby generating a corresponding detection signal, and then providing a control circuit, and the control circuit is electrically connected to the spectrum detection circuit and the extinction lamp respectively, so that the control circuit controls the on and off of the extinction lamp according to the detection signal.

[0043] To ensure complete removal of surface charge from the photosensitive drum, existing technology requires that the light emitted by the lamp at a specific voltage meet the required wavelength intensity. Unfortunately, this wavelength intensity is difficult to determine visually. While sophisticated spectral detection equipment exists on the market that can accurately analyze the wavelength intensity of the light source, such equipment is generally expensive and slow, making it more commonly used as an auxiliary tool for parameter testing rather than a direct measurement method on the production line.

[0044] The present application provides a solution that improves the detection accuracy and efficiency of discharge lamps during the production process and solves the production detection problem of discharge lamps in printer and copier components.

[0045] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the detection circuit includes a discharge lamp 100, a spectrum detection circuit 200, and a control circuit 300, wherein:

[0046] The spectrum detection circuit 200 includes a spectrum sensor 210, which is arranged at the light source of the de-energizing lamp 100. The spectrum detection circuit 200 is used to receive the light source of the de-energizing lamp 100, detect the intensity of each wavelength of the light source, and generate a corresponding detection signal. The first input terminal of the control circuit 300 is connected to the output terminal of the spectrum detection circuit 200, and the control terminal of the control circuit 300 is connected to the controlled terminal of the de-energizing lamp 100. The control circuit 300 is used to control the on and off of the de-energizing lamp 100 based on the detection signal.

[0047] In this embodiment, the spectrum detection circuit 200 is an integrated, high-precision spectrum analysis module that incorporates advanced optical filters and photoelectric conversion elements, enabling precise capture and conversion of the optical signal emitted by the de-energizing lamp 100 into an electrical signal. This design not only reduces the complexity and size of the detection circuit but also significantly improves the response speed and accuracy of spectrum detection. The optical filter selectively allows light of specific wavelengths to pass through, effectively filtering out interfering light and ensuring accurate spectrum detection. The photoelectric conversion element efficiently converts the filtered optical signal into an electrical signal for subsequent processing circuitry.

[0048] The control circuit 300 may be implemented using a main controller, such as an MCU (Micro controller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), or a SOC (System on Chip).

[0049] Optionally, the model of the spectrum sensor 210 is AS7343, and the detection wavelength of the spectrum sensor 210 is 395 nm to 865 nm.

[0050] In this embodiment, the AS7343 is a 14-channel, multifunctional, and versatile spectral sensor 210. It responds to wavelengths between 395nm and 865nm with high sensitivity, meeting the wavelength testing requirements of the anti-static lamp 100 used in printers and copiers. It can quickly and accurately analyze the light intensity of the anti-static lamp 100 in each channel, i.e., each wavelength band. The sensor also integrates an I2C interface, converting analog wavelength intensity measurements into digital signals and exchanging information with the main control unit via this I2C interface.

[0051] This embodiment comprises an anti-discharge lamp 100 and a spectrum detection circuit 200, wherein the spectrum detection circuit 200 includes a spectrum sensor 210. The spectrum sensor 210 is disposed at the light source of the anti-discharge lamp 100, so that the spectrum detection circuit 200 is used to receive the light source of the anti-discharge lamp 100 and detect the intensity of each wavelength of the light source, thereby generating a corresponding detection signal. A control circuit 300 is further provided and electrically connected to the spectrum detection circuit 200 and the anti-discharge lamp 100, respectively, so that the control circuit 300 controls the on and off of the anti-discharge lamp 100 based on the detection signal, thereby improving the detection accuracy and efficiency of the anti-discharge lamp 100 during the production process and solving the production detection problem of the anti-discharge lamp 100 in the drum assembly of printers and copiers.

[0052] Optionally, refer to Figure 3 Another embodiment of the present invention provides a detection circuit for a discharge lamp 100. Figure 1 and Figure 2 In the embodiment shown, the control circuit 300 includes:

[0053] A control chip 310 , wherein an input terminal of the control chip 310 is connected to an output terminal of the spectrum detection circuit 200 ;

[0054] A driving circuit 320, wherein a controlled terminal of the driving circuit 320 is connected to a control terminal of the control chip 310, and the control terminal of the driving circuit 320 is connected to a controlled terminal of the discharge lamp 100;

[0055] The control chip 310 is used to output the corresponding control circuit 300 to the driving circuit 320 according to the detection signal, so as to control the on and off of the discharge lamp 100.

[0056] In this embodiment, the control chip 310 serves as the core processing unit of the entire detection circuit, responsible for receiving detection signals from the spectrum detection circuit 200 and rapidly analyzing and processing them. Based on a pre-set algorithm or logical judgment, the control chip 310 accurately determines whether the intensity of each wavelength of the light source meets preset standards and, therefore, determines whether the on / off state of the anti-static lamp 100 needs to be adjusted. This design enables real-time monitoring and precise control of the light quality of the anti-static lamp 100, effectively improving the automation and intelligent level of the production line.

[0057] The driver circuit 320 serves as a bridge between the control chip 310 and the discharge lamp 100. Its function is to convert control signals from the control chip 310 into electrical signals that directly drive the discharge lamp 100. Upon receiving instructions from the control chip 310, the driver circuit 320 quickly responds by adjusting the current or voltage supplied to the discharge lamp 100, achieving precise control of the discharge lamp's on / off state. Furthermore, the driver circuit 320 incorporates safety features such as overload and short-circuit protection, ensuring that power is promptly cut off in the event of an abnormality, protecting the entire detection circuit and the discharge lamp 100 from damage.

[0058] The driver circuit 320 can be an H-bridge driver circuit based on MOSFETs (metal oxide semiconductor field-effect transistors). This circuit structure enables bidirectional current control of the de-energizing lamp 100, allowing it to not only illuminate but also quickly extinguish when needed. Through the clever configuration of four MOSFETs, the H-bridge driver circuit flexibly switches the direction of current flow, thereby enabling on / off and brightness adjustment of the de-energizing lamp 100. In a specific implementation, the control chip 310 uses PWM (pulse width modulation) signals to control the on and off times of the MOSFETs, thereby adjusting the current flowing through the de-energizing lamp 100 to precisely control its brightness.

[0059] Optionally, the model of the control chip 310 is STM32F103.

[0060] In this embodiment, the control chip 310 utilizes the STM32F103 chip, featuring an ARM Cortex M3 core and a maximum clock speed of 72 MHz. This speed allows for high-speed analysis of data transmitted by the spectral sensor 210. It also features a rich set of interfaces, such as I2C, SPI, and USART, facilitating efficient communication with the spectral sensor 210 (AS7343). The STM32F103 also integrates multiple timers, ADCs (analog-to-digital converters), and DACs (digital-to-analog converters), providing powerful hardware support for spectral data acquisition and processing. Its low power consumption also meets the energy conservation and emission reduction requirements of modern industrial production.

[0061] Optionally, refer to Figure 4 Another embodiment of the present invention provides a detection circuit for a discharge lamp 100. Figures 1 to 3 In any of the illustrated embodiments, the detection circuit further includes an interactive circuit 400, wherein:

[0062] The input end of the interactive circuit 400 is connected to the output end of the control circuit 300 , and the output end of the interactive circuit 400 is connected to the second input end of the control circuit 300 . The interactive circuit 400 is used to output an operation signal or receive a display signal output by the control circuit 300 .

[0063] In this embodiment, interactive circuit 400 acts as a bridge between the detection circuit and the user, greatly enhancing the system's interactivity and ease of use. This circuit integrates multiple input and output interfaces, such as buttons, a touch screen, an LED display, or an LCD screen, allowing the user to intuitively understand the detection status of the discharge lamp 100 and to intervene or adjust the detection process through simple operations.

[0064] The input of interactive circuit 400 is connected to the output of control circuit 300. This means that control circuit 300 can visually or audibly present the current detection status, results, or information requiring user attention to the user through interactive circuit 400. For example, if the luminous intensity of the discharge lamp 100 does not meet a preset standard, control circuit 300 can send a signal to interactive circuit 400, driving the LED display to display a "luminous abnormality" prompt or sounding an alarm through a buzzer to attract the user's attention.

[0065] At the same time, the output terminal of the interactive circuit 400 is connected to the second input terminal of the control circuit 300, allowing the user to send operation signals to the control circuit 300 through input devices such as buttons and touch screens. These operation signals may include instructions such as starting and stopping detection, adjusting detection parameters, etc., allowing users to flexibly control the detection process according to their needs.

[0066] Optionally, refer to Figure 5 Another embodiment of the present invention provides a detection circuit for a discharge lamp 100. Figure 4 In the illustrated embodiment, the interactive circuit 400 includes a display circuit 410, wherein:

[0067] An input end of the display circuit 410 is connected to an output end of the control circuit 300 , and the display circuit 410 is configured to receive a display signal output by the control circuit 300 .

[0068] In this embodiment, display circuit 410, a key component of interactive circuit 400, refines the information presentation between the detection circuit and the user. Using its high-definition display (such as an LCD or OLED screen), display circuit 410 provides real-time, intuitive display of various detection parameters and status information of the de-energizing lamp 100. This information includes not only the intensity data for each wavelength of the light source but also key information such as the lamp's on / off status, detection progress, remaining time, and abnormality alarms.

[0069] The display circuit 410 can also be designed with a user-friendly interface (UI), presenting data in a graphical and intuitive manner, enabling users to quickly understand and take appropriate actions. This interface may include multiple viewing modes, such as real-time data, historical records, and settings adjustment views, to meet the needs of different users in different scenarios. Furthermore, the display circuit 410 features a high response speed and refresh rate, ensuring that any subtle changes during the inspection of the discharge lamp 100 are captured and displayed to the user in a timely manner. This instant feedback mechanism is crucial for improving inspection accuracy and optimizing production processes.

[0070] Optionally, the display circuit 410 includes at least one of an OLED screen, a TFT screen, and an LCD display screen.

[0071] In this embodiment, the display circuit 410 utilizes a variety of materials to accommodate diverse application scenarios. OLED screens, with their self-luminous, high contrast, wide viewing angle, and ultra-thin design, are a high-end choice for the display circuit 410. They not only display vibrant colors but also maintain excellent display quality even in low-light conditions, making them ideal for use in inspection environments requiring detailed displays and a superior visual experience. Furthermore, OLED screens offer low power consumption and a fast response time, further enhancing the overall performance of the inspection circuit.

[0072] Secondly, TFT screens, with their high resolution, high brightness, and excellent color reproduction, are also a common component in display circuit 410. TFT screens are widely used in various electronic devices and display screens. Their stable performance and mature technology make them equally important in the detection circuit of discharge lamp 100. TFT screens are particularly effective when displaying large amounts of data and complex charts simultaneously, providing clearer and more detailed visual information.

[0073] Furthermore, LCD displays, as a representative of traditional display technology, may not be as advanced as OLED and TFT screens in some aspects, but their low cost, high reliability, and wide application base make them the preferred choice in many situations. In the detection circuit of the discharge lamp 100, LCD displays can meet basic display requirements, such as displaying detection parameters and status information, and their relatively affordable price makes them suitable for large-scale applications.

[0074] In addition to the display screen, the display circuit 410 in this embodiment can further integrate touch functionality to form a touchscreen display circuit 410. The addition of a touchscreen not only improves user convenience but also provides the detection circuit with a more intuitive and interactive interface. Users can switch display views, adjust detection parameters, or execute other control commands through simple touch operations, greatly improving the efficiency of the detection process and user experience.

[0075] Optionally, refer to Figure 6 Another embodiment of the present invention provides a detection circuit for a discharge lamp 100. Figure 4 In the illustrated embodiment, the interactive circuit 400 includes a button circuit 420, wherein:

[0076] An output terminal of the button circuit 420 is connected to a second input terminal of the control circuit 300 . The button circuit 420 is configured to output an operation signal to the control circuit 300 .

[0077] In this embodiment, the button circuit 420 serves as another important input method in the interactive circuit 400, providing the user with a direct and reliable means of operation. Compared with the touch screen, the button circuit 420 may be more applicable in certain specific environments, such as when there is touch interference, a quick response is required, or there are high requirements for waterproof and dustproof. The button circuit 420 can generally be composed of multiple physical buttons, each button corresponding to a different function or instruction. These buttons are connected to the second input terminal of the control circuit 300 through a circuit. When the user presses a button, the button circuit 420 immediately generates a corresponding electrical signal and sends it to the control circuit 300 for processing. The control circuit 300 identifies the user's operating intention based on the received signal, and performs corresponding actions or adjusts the detection parameters accordingly.

[0078] In this embodiment, the button circuit 420 may include various types of buttons, such as switch-type buttons, touch-type buttons, or buttons with LED indicators. Switch-type buttons are the most common type, which implement signal on / off by mechanically connecting and disconnecting the button. Touch-type buttons use capacitance or resistance principles to detect user touch actions, and have higher sensitivity and longer service life. Buttons with LED indicators can light up when the button is pressed to provide additional visual feedback to help users confirm the success or failure of the operation.

[0079] In addition to basic operating functions, button circuit 420 may also integrate special function buttons, such as an emergency stop button, a reset button, or a mode switch button. The emergency stop button is used to immediately interrupt the detection process in an emergency, ensuring the safety of equipment and personnel. The reset button is used to restore the detection circuit to its initial state so that detection can be restarted. The mode switch button allows the user to switch between different detection modes to meet different detection requirements.

[0080] Alternatively, refer to Figure 7 Another embodiment of the present invention provides a detection circuit for a discharge lamp 100. Figures 1 to 3 In any of the illustrated embodiments, the detection circuit further includes a power supply circuit 500, wherein:

[0081] The input end of the power supply circuit 500 is used to connect to the mains power, and the output end of the power supply circuit 500 is electrically connected to the de-energizing lamp 100, the spectrum detection circuit 200 and the control circuit 300 respectively. The power supply circuit 500 is used to convert the voltage of the mains power into the corresponding supply voltage of the de-energizing lamp 100, the spectrum detection circuit 200 and the control circuit 300.

[0082] In this embodiment, the power supply circuit 500 serves as the heart of the entire detection circuit. Its stability and reliability are directly related to the proper operation of the detection circuit. To ensure that the discharge lamp 100, spectrum detection circuit 200, and control circuit 300 receive a stable and appropriate supply voltage, the power supply circuit 500 utilizes efficient and precise voltage conversion technology.

[0083] In this embodiment, the power supply circuit 500 first pre-processes the incoming mains power through a filtering circuit to remove noise and interference from the power grid, ensuring the purity of the subsequent voltage conversion process. Subsequently, a transformer or switching power supply is used to convert the high mains voltage (typically 220V or 110V) into a low voltage (e.g., 5V, 12V, 24V, etc.) suitable for each functional module. During the voltage conversion process, the power supply circuit 500 also performs necessary voltage stabilization and current limiting to prevent damage to circuit components due to voltage fluctuations or excessive current.

[0084] In addition to basic power supply functions, the power supply circuit 500 in this embodiment can further integrate power management functions. Through a built-in power management chip or microcontroller, the power supply circuit 500 can distribute, monitor, and manage power to various functional modules. For example, during the detection process, if a functional module experiences an abnormality or failure, the power management circuit can immediately cut off power to that module to prevent the fault from spreading and damaging other modules. Furthermore, the power management circuit can record and analyze power consumption data for each module, providing a basis for subsequent energy-saving optimization and performance improvement.
