Description

Technical Field

[0001] The utility model relates to the technical field of printing, and more specifically to a device integrating a multi-channel grating, a network and a power supply. Background Art

[0002] With the increasing application of digital inkjet printing, industrial printers are also flourishing. In particular, the development of different industrial printheads requires not only the selection of appropriate solutions from a technical perspective, but also the selection of appropriate solutions from an architectural perspective. Currently, there are two mainstream architectures for digital inkjet printers. One is a customized architecture, where a control board controls multiple printheads. The selection of the appropriate number of printheads is generally affected by parameters such as structure, power supply, and data flow. The requirements for this customized architecture must be clear, such as the need to determine a clear number of printheads, etc. Generally, the number of printheads is ≤16, and it is common in small flatbed printers. This customized architecture is not flexible enough and cannot meet the needs of more printers; the other is a general architecture, where a control board controls a printhead, and the printheads are integrated with IP. This structure is common in large industrial printers, monochrome printers, and other special industrial printers. In this structure, the integrated IP of printheads has become an increasingly important module, and the power lines, trigger lines, and communication lines between each module become more and more complicated as the number of printheads increases. The cost and technical requirements for maintenance will become higher and higher, which is not only extremely inconvenient for the efficiency and maintenance of equipment assembly, but also makes the entire spray truck very complicated.

[0003] Therefore, in order to solve the problems of inflexible architecture, redundant wires, high maintenance costs and high technical requirements in the prior art, this patent provides a device with multi-channel integrated gratings, gigabit networks and power supplies. Utility Model Content

[0027] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides a multi-channel integrated grating, network and power supply device, the device includes: a power supply unit, a network unit and a data unit, which are used to integrate power supply signals, network signals and grating signals; wherein,

[0030] The power supply unit includes a power input port and a plurality of power output ports, which are used to integrate the power signal between the nozzle and the external power supply;

[0031] The network unit includes a switch chip and several network interfaces, which are used to integrate the network signals between several print heads, PC computers and software modules, and realize IPization of print heads and print head modules;

[0032] The data unit comprises an integrated chip, a plurality of signal input terminals, a plurality of signal output terminals and a signal conversion component, and is used for integrating data signals between a plurality of nozzles and external sensors.

[0033] Since the nozzles and nozzle modules are IP-based in the general architecture, the difficulty of developing the software system and the nozzle module is greatly reduced. However, as the equipment becomes larger and more scalable, the complexity of its wires becomes more and more complex. Therefore, a device is provided in the utility model to integrate the wires, making wiring simpler and easier to maintain.

[0034] Specifically, in this embodiment, the device can be a grating network 1×6 secondary distribution board, such as Figure 1 As shown, the input signal can be integrated accordingly, and as more and more nozzle components are connected, the wiring becomes more and more complicated. In order to make the wiring of the printing system simpler, the device can also be cascaded, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the cascade connection of a 1×6 secondary distribution board of a grating network provided in this embodiment. Figure 2 It can be seen that the device uses its own properties to integrate all grating, network, and power input signals, which greatly simplifies wiring, thereby making the wiring distribution of the entire printing system organized, making problems easier to detect and maintain.

[0035] Preferably, in the data unit, the signal input terminal includes a differential grating / magnetic grating signal input terminal and a single-ended grating / magnetic grating signal input terminal, such as Figure 3 As shown, Figure 3 The schematic diagram of the structure of the grating network 1×6 secondary distribution board provided in this embodiment, wherein Figure 3P8 is a differential grating / magnetic grating signal input terminal, and P15 is a single-ended grating / magnetic grating signal input terminal. Different types of input ports are set to receive different types of incoming data signals. Among them, since the single-ended grating signal is a signal directly read from one grating unit or a combination of multiple grating units, and the differential grating signal is a signal processing method that uses the differential measurement method between two grating units to obtain higher accuracy and better anti-interference ability, the choice of using a single-ended or differential signal depends on the requirements of the specific application, including factors such as accuracy, noise suppression requirements, and system design complexity. Setting two different types of input ports can further adapt to the needs of actual applications and increase the practicality of the device.

[0036] Preferably, if Figure 4 As shown, Figure 4 This is a schematic diagram of the data unit of this embodiment. Figure 4 It can be seen that the signal conversion component includes a differential-to-single-ended component and a single-ended-to-differential component, which are used to convert data signals, wherein the integrated chip can be a 74 chip, and one end of the differential-to-single-ended component is connected to the signal input end, and the other end is connected to the input end of the 74 chip; the two signal lines (positive and negative polarities) of the differential signal are converted into a single signal line through the differential-to-single-ended component, so that the single-ended signal input into the chip is easier to be processed and transmitted to the chip receiving end;

[0037] In addition, the 74 series logic chips (such as 74LS, 74HC, etc.) usually accept single-ended logic levels as their input. Therefore, if the input signal is a differential signal, it needs to be converted into a single-ended signal first, and then input into the 74 chip for logic processing. After the processing is completed, the single-ended to differential component is connected to the output end of the 74 chip at one end and connected to several signal output ends at the other end to convert the single signal line into two signal lines (positive and negative polarity) for easy transmission and to meet the needs of the receiving end, such as Figure 3 As shown, Figure 3 P9-P14 are grating signal output ports, through which the signal is output to each nozzle or nozzle universal module, so as to ensure the adaptation and transmission quality of the signal and meet the input and output requirements of the device or chip.

[0038] Preferably, if Figure 5 As shown, in the network unit, the network interface is a gigabit network interface for realizing high-speed communication; wherein, a plurality of network interfaces are connected to the input end of the switch chip, and a plurality of network interfaces are connected to the output end of the switch chip. In the grating network 1x6 secondary distribution board provided in this embodiment, the switch chip can be an 8-port switch chip, and the switch chip is used to integrate network signals. Figure 3 P16-P23 are Gigabit network interfaces, optionally, Figure 2 As shown, two of the gigabit network interfaces are used as input signal receivers and connected to the input end of the switch chip, so that the redundant wires in the printing system can be integrated, and the synchronization and anti-interference of high-speed communication can be ensured.

[0039] Preferably, as Figure 6 shown, since the device provided in this embodiment is a secondary distribution board of the raster network 1x6 specification, it includes 6 output power supplies. Combining Figure 3 shown, Figure 3 in which P2 - P7 are the 6 independent output power supplies, and P1 is the input power supply, thus realizing the integration of the power signal wires; in addition, in this embodiment, the power supply unit also includes voltage stabilization and power distribution components for providing stable power supply to various parts of the device.

[0040] Preferably, as Figure 3 shown, the device further includes an indicator light unit, which includes a power indicator light, several network interface indicator lights, and several raster signal change indicator lights, and are respectively arranged on the power supply unit, the network unit, and the sensor unit. Among them, Figure 3 in which LD1 is the power indicator light, LD3 and LD4 are the raster signal change indicator lights, and there are indicator lights in each gigabit network structure for displaying the status of relevant units. Thus, by setting the indicator lights, relevant staff can quickly understand the status of the device, and then take corresponding operation or maintenance measures, improving the usability of the device and the convenience of operation.

[0041] Further preferably, the number n of the raster signal change indicator lights is at least set to 2. When the status is normal, the two raster signal change indicator lights are always on, so as to be able to detect whether the status of the signal is abnormal.

[0042] Preferably, the range of the input voltage Vin of the device is 7V < Vin < 40V. In actual operation, the input voltage can fluctuate within this range without affecting the normal function of the device.

[0043] Preferably, the range of the differential signal voltage U of the device is 4.5V < U < 5.5V.

[0044] Preferably, when the input voltage Vin is the standard voltage 36V, the maximum current Imax of the device < 0.3A.

[0045] By setting the usage ranges of relevant parameters such as voltage and current, the performance of the device can be ensured, and its damage and impact on the use of the device can be avoided.

[0046] Further preferably, in addition to the 1×6 distribution board mentioned in this embodiment, the present device may also adopt other specifications, such as 1×8, 1×10, 1×12 and the like. The specific specification settings can be selected according to actual needs. Correspondingly, the number of interfaces in each unit in the device is also adjusted accordingly, so as to achieve corresponding integration and optimization of wire redundancy and the like existing in the prior art, thereby improving the flexibility of the architecture, making the printing system simpler and clearer, and improving the installation efficiency, reliability and debuggability of the equipment, while also ensuring the synchronization and anti-interference of high-speed communication.
