Description

Technical Field

[0001] The present invention relates to the technical field of ceramic production equipment, and in particular to an inkjet printing system for printing two-dimensional codes and logos on ceramic products. Background Art

[0002] Currently, product labels for ultra-high voltage materials are manually applied, which is time-consuming and labor-intensive, and does not allow for product differentiation or traceability. While some existing technologies utilize QR codes to trace product information, these technologies are difficult to apply to ceramic manufacturing. Summary of the Invention

[0003] In response to the problems existing in the prior art, the purpose of the present invention is to provide an inkjet printing system suitable for ceramic production that generates QR codes and prints QR codes and LOGOs.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions.

[0005] An inkjet printing system for generating a QR code and printing the QR code and a LOGO is characterized in that it comprises a first inkjet printer, an automatic code scanner and a second inkjet printer which are sequentially arranged on a ceramic product production line, wherein the first inkjet printer and the automatic code scanner are located before a glazing process, and the second inkjet printer is located after the glazing process; the first inkjet printer generates a QR code according to a rule and prints the QR code on a blank for the first time, the automatic code scanner is responsible for identifying the QR code on the blank and transmitting it to the second inkjet printer, and the second inkjet printer is responsible for printing the same QR code and a customer-specified LOGO pattern for a second time.

[0006] More preferably, a counter is used to count the number of blanks entering the automatic code scanner; there are n workstations between the glazing process and the second inkjet printer, and when the count reaches the nth blank entering the automatic code scanner, the second inkjet printer is controlled to start printing the QR code for the second time.

[0007] More preferably, the QR code includes product model information, production date information and serial number information.

[0008] More preferably, the ink used by the first inkjet printer is ink that does not develop color after firing, and the ink used by the second inkjet printer is ink that develops color after firing.

[0009] More preferably, the first inkjet printer and the second inkjet printer both include: a conveyor belt, a nozzle arranged above the conveyor belt, and an operation display connected to the nozzle.

[0010] More preferably, the nozzle is rotatably mounted on a frame to form an adjustable spray angle structure; a rotatably mounted supporting plate is provided on the frame, and the inclination angle is adjusted between the supporting plate and the frame by means of mutually cooperating threaded rods and pull rods, and the nozzle is mounted on the supporting plate.

[0011] More preferably, the operation display of the first inkjet printer is used to input the product model and production date, and the operation display of the second inkjet printer is used to input the LOGO mark to the corresponding print head.

[0012] More preferably, the first inkjet printer and the second inkjet printer are connected to a host computer, and the host computer inputs the product model, production date and LOGO.

[0013] More preferably, the second inkjet printer includes two groups of the nozzles, one of the nozzles in each group is used to print the QR code and the other is used to print the LOGO; different groups of nozzles have different printing colors.

[0014] More preferably, the automatic code scanner includes: an industrial code reader, a machine vision lens, a machine vision light source and a light source controller; the industrial code reader is used to convert the captured QR code into data, the machine vision lens is used to capture the QR code on the blank and identify the features, the machine vision light source provides a good lighting environment during shooting, and the light source controller is used to cooperate with the light source to provide power and trigger signals.

[0015] The above technical solution can achieve the following technical effects.

[0016] 1. By setting up the first and second inkjet printers, a QR code can be automatically generated according to the product information and production date, without the need to manually paste the product information and LOGO pattern; and the generated QR code and LOGO pattern can remain on the product surface for a long time, and the information at the time of product production can be traced at any time.

[0017] Second, by installing an automatic code scanner before the glazing process and a second inkjet printer connected to the automatic scanner after the glazing process, the problem of glaze blocking the QR code and causing inaccurate recognition can be avoided. At the same time, a counter is used to count the number of blanks entering the automatic code scanner to ensure the consistency of the second-printed QR code with the first-printed QR code.

[0018] 3. Since the ink of the QR code printed for the first time does not show color after firing, the ink of the QR code printed for the second time shows color after firing, which effectively avoids the interference between the two printed QR codes and also ensures the quality of the product.

[0019] 4. By setting corresponding operation displays on the first inkjet printer and the second inkjet printer, it is convenient to re-compile the corresponding QR code encoding rules and select different LOGO patterns according to different customer requirements.

[0029] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention.

[0030] like Figure 1 As shown, an inkjet printing system for generating a QR code and printing a QR code and a LOGO is characterized in that it includes a first inkjet printer 1, an automatic code scanner 2 and a second inkjet printer 3 which are sequentially arranged on a ceramic product production line, the first inkjet printer 1 and the automatic code scanner 2 being located before a glazing process 4, and the second inkjet printer 3 being located after the glazing process 4; the first inkjet printer 1 generates a QR code according to a rule and prints the QR code onto a blank 5 for the first time, the automatic code scanner 2 is responsible for identifying the QR code 5-1 on the blank 5 and transmitting it to the second inkjet printer 3, and the second inkjet printer 3 is responsible for printing the same QR code 5-1 and the customer-specified LOGO 5-2 (product identification) for the second time.

[0031] Among them, the QR code includes product model information, production date information and serial number information. The product model is manually entered by the operator, the font and layout are editable, and it consists of English letters and numbers. The date uses the date of the day (year, month, and day). The serial number system automatically sorts and generates it. For example, the date format of the day is: 20200522. Serial number: 4 digits, serial number from 0000 to 9999, and those that are not used up on the same day will not be used again. The product model and date + serial number are not related to each other. When the product model changes, the serial number is recounted; if a model appears twice on a certain day, it should automatically continue with the previous serial number of the day.

[0032] In this embodiment, a counter 6 is used to count the number of blanks entering the automatic code scanner 2. There are n stations between the glazing process 4 and the second inkjet printer 3. When the nth blank enters the automatic code scanner 2, the second inkjet printer 3 is controlled to begin printing the QR code for the second time. This ensures the accuracy of the second QR code print, and the structure is simple and easy to implement. The counter 6 is preferably a photoelectric eye counting device.

[0033] In this embodiment, the ink used by the first inkjet printer 1 is an ink that does not develop color after firing, and the ink used by the second inkjet printer 3 is preferably an ink that develops color after firing; in this way, after the product is fired, the QR code printed for the first time completely disappears, and only the QR code printed for the second time is retained to avoid mutual interference.

[0034] Combine Figure 2 As shown, the first inkjet printer 1 and the second inkjet printer 3 both include: a conveyor belt 7, a nozzle 8 arranged above the conveyor belt 7, and an operation display 9 connected to the nozzle 8.

[0035] In this embodiment, the spray head 8 is rotatably mounted on a frame 10, forming an adjustable spray angle structure. Specifically, a rotatably mounted support plate 11 is provided on the frame 10. The support plate 11 and the frame 10 are connected by a threaded rod 12 and a tie rod 13 that cooperate to adjust the inclination angle. The spray head 8 is mounted on the support plate 11. To facilitate adjustment of the relative position between the threaded rod 12 and the tie rod 13, a rotating handle 14 is preferably connected to the tie rod 13.

[0036] In this embodiment, the operation display of the first inkjet printer 1 is used to input the product model and production date, and the operation display of the second inkjet printer 3 is used to input the logo mark to the corresponding inkjet printer. In other embodiments, the first inkjet printer and the second inkjet printer are connected to a host computer, and the host computer inputs the product model, production date and logo mark; this is not limited to this embodiment.

[0037] It should be noted that the second inkjet printer 3 includes two groups of nozzles, one of each group of nozzles is used to print the QR code and the other is used to print the LOGO; different groups of nozzles have different printing colors, and when one group of nozzles is printing, the other group of nozzles does not need to print. Figure 1 The C and M in the figure represent two ink color codes respectively. In this way, you can choose different ink sets to print according to different blank colors, which has good compatibility.

[0038] It should also be noted that the automatic barcode scanner includes an industrial barcode reader, a machine vision lens, a machine vision light source, and a light source controller. The industrial barcode reader converts captured QR codes into data, the machine vision lens captures and identifies the QR codes on the blanks, the machine vision light source provides a good lighting environment for capturing images, and the light source controller provides power and trigger signals for the light source. During operation, the automatic barcode scanner automatically captures the appearance features of the QR code on the blanks, converts the code content into data, and transmits it via TCP data mode to the host computer of the second inkjet printer.

[0039] Compared with the existing technology, the inkjet printing system provided in this embodiment uses an inkjet machine to intelligently generate a QR code and a LOGO and print them on ceramic blanks, which can meet customers' requirements for ceramic product information traceability; at the same time, the production efficiency is high, up to 3,000 pieces / day (24 hours).

[0040] Through the description of the above structure and principle, those skilled in the art should understand that the present invention is not limited to the above specific embodiments. Improvements and substitutions based on the present invention using the known technology in the art fall within the scope of protection of the present invention, which is defined by the claims and their equivalents. Any parts not described in the specific embodiments are prior art or common knowledge.
