Abstract
Description
Technical Field
[0001] This application relates to the field of inkjet printing, and more particularly to an inkjet printing device and inkjet printing system. Background Technology
[0002] In the traditional glass display screen shading area production process, the shading area adopts a first-coverage spray coating and then exposure process. The first-coverage spray coating and then exposure process has disadvantages such as high pollution, high energy consumption, low precision, ultra-long process flow, and multiple manual interventions. With the development of the times, technological progress and the urgent need for energy conservation and emission reduction, industrial automated printing equipment has emerged to replace the traditional first-coverage spray coating and then exposure process.
[0003] Traditional glass display screen light-shielding area production process requires covering the entire glass substrate with a special photoresist for light-shielding areas, and then removing the unwanted parts using exposure equipment, leaving the graphic area that meets production requirements. This process is complex, inefficient, and wasteful of raw materials.
[0004] Therefore, how to improve the production efficiency of products to be printed has become an urgent problem to be solved in this field. Utility Model Content
[0005] The purpose of this application is to provide a printing device and printing system, which aims to improve the production efficiency of products to be printed.
[0006] This application discloses a printing device, including a guide rail, a movable frame, and a printing platform. The guide rail is connected to the printing platform and has a preset height relative to the printing platform. The movable frame is movably connected to the guide rail and can move along the extension direction of the guide rail. A printing platform is provided on the printing platform for holding the product to be printed. A printhead, an ink cartridge, and a curing device are provided on the movable frame. The printhead is connected to the ink cartridge, and the curing device is located on the side of the printhead away from the printing platform. The printhead is used to print the product to be printed according to a preset pattern, and the curing device cures the ink on the product to be printed during the printing process.
[0007] Optionally, the curing apparatus includes an ultraviolet curing apparatus, which is used to irradiate the ink on the product to be printed with ultraviolet light.
[0008] Optionally, a support rod is provided between the guide rail and the machine base. The support rod includes a first support rod and a second support rod. One end of the second support rod is connected to the machine base. The end of the second support rod away from the machine base has an opening. The first support rod passes through the opening and is sleeved inside the second support rod. The first support rod is movable relative to the second support rod. The end of the first support rod away from the second support rod is connected to the guide rail.
[0009] Optionally, the printing equipment further includes a housing, in which the guide rail, the movable frame, and the printing platform are all disposed.
[0010] Optionally, the housing is provided with a first window, which is used to partially expose the space inside the housing.
[0011] Optionally, the printing equipment further includes a printhead cleaning device, which is disposed on the machine platform and correspondingly disposed below the guide rail. After the printhead finishes printing, the printhead is removed from the printing platform and moved above the printhead cleaning device, which is used to clean the residual ink on the printhead.
[0012] Optionally, the movable frame is also equipped with an image detection device, which is used to detect whether the printhead is aligned with the product to be printed at a preset position.
[0013] Optionally, the movable frame is also equipped with a height detection device, which is used to detect the distance between the printhead and the printing platform.
[0014] Optionally, the printing equipment further includes an alarm device connected to the height detection device. When the height detection device detects that the distance between the printhead and the printing platform is less than or greater than a first preset distance, the height detection device transmits a detection signal to the alarm device, and the alarm device is in a first state. When the height detection device detects that the distance between the printhead and the printing platform is equal to the first preset distance, the height detection device transmits a detection signal to the alarm device, and the alarm device is in a second state.
[0015] This application also discloses a printing system, including a host computer, and the printing system further includes the aforementioned printing equipment, with the host computer connected to the printing equipment.
[0016] This application improves inkjet printing equipment by integrating the printhead and curing device onto the same movable frame, which moves along a guide rail. This allows the printhead to move along a predetermined path under precise control, ensuring high accuracy and consistency of the printed pattern. While the printhead is printing on the product, the curing device immediately follows, curing the area just printed. This eliminates the need to wait for the ink to dry naturally, ensuring the ink does not spread or deform, thus guaranteeing printing quality and forming the predetermined pattern on the product. This eliminates the need for covering and exposing the printing material, reducing manual intervention, operational difficulty, and error rates. It effectively improves production efficiency and saves costs. Attached Figure Description

Detailed Implementation
[0027] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Figure 1 This is a schematic diagram of the first embodiment of the inkjet printing equipment of this application, as shown. Figure 1 As shown in the figure, this application discloses a printing device 100, including a guide rail 110, a movable frame 120, and a machine base 130. The guide rail 110 is connected to the machine base 130 and has a preset height relative to the machine base 130. The movable frame 120 is movably connected to the guide rail 110 and can move along the extension direction of the guide rail 110. A printing platform 131 is provided on the machine base 130, which is used to hold the product to be printed. A printhead 121, an ink cartridge 122, and a curing device 123 are provided on the movable frame 120. The printhead 121 is connected to the ink cartridge 122, and the curing device 123 is located on the side of the printhead 121 away from the printing platform 131. The printhead 121 is used to print the product to be printed according to a preset pattern, and the curing device 123 cures the ink on the product to be printed during the printing process of the printhead 121.
[0029] This application improves the inkjet printing equipment 100 by integrating the printhead 121 and the curing device 123 onto the same movable frame 120, which moves along the guide rail 110. This allows the printhead 121 to move along a predetermined path under precise control, ensuring high accuracy and consistency of the printed pattern. While the printhead 121 is printing on the product, the curing device 123 immediately follows the printhead 121, curing the area just printed. This eliminates the need to wait for the ink to dry naturally, allowing for immediate curing after printing. This ensures the ink does not spread or deform, guaranteeing printing quality and forming a predetermined pattern on the product. This eliminates the need for covering or exposing the printing material, reducing manual intervention, operational difficulty, and error rate. It effectively improves production efficiency and saves costs.
[0030] Specifically, in this application, the curing apparatus 123 includes an ultraviolet curing apparatus 124, which is used to irradiate the ink on the product to be printed with ultraviolet light. The ultraviolet curing apparatus 124 can be a UV lamp or a UV curing device.
[0031] This application utilizes an ultraviolet curing device 124 that can closely follow the printhead 121. While the printhead 121 is printing the product to be printed, it emits ultraviolet light to irradiate the ink, causing the ink to quickly change from a liquid state to a solid state. This greatly shortens the production cycle and the instant curing avoids the problem of traditional solvent-based inks requiring a long drying time, thus improving overall production efficiency.
[0032] In addition, the UV curing process ensures that the ink is fixed immediately after printing, avoiding the problem of blurred patterns caused by diffusion or deformation, which helps to improve the printing effect.
[0033] It should be noted that the inkjet printing equipment 100 of this application can print on the light-shielding layer in the non-display area of the display screen. By using the inkjet printing equipment 100 of this application to print and cure ink at the same time, the steps of covering the entire surface of the glass substrate with special photoresist and then removing the unwanted parts by exposure equipment can be simplified. This simplifies the production process, improves production efficiency and saves costs.
[0034] In this application, the printhead 121 can add ink or photoresist and other materials into the ink cartridge 122 according to actual needs. Therefore, in addition to curing ink, the ultraviolet curing device 124 of this application can also be used for curing other printing materials such as photoresist.
[0035] Figure 2 This is a schematic diagram of a second embodiment of the inkjet printing equipment of this application, as shown below. Figure 2 As shown, a support rod 140 is provided between the guide rail 110 and the machine base 130. The support rod 140 includes a first support rod 141 and a second support rod 142. One end of the second support rod 142 is connected to the machine base 130, and the end of the second support rod 142 away from the machine base 130 has an opening 143. The first support rod 141 passes through the opening 143 and is sleeved inside the second support rod 142. The first support rod 141 is movable relative to the second support rod 142. The end of the first support rod 141 away from the second support rod 142 is connected to the guide rail 110.
[0036] In this embodiment, a support rod 140 is provided between the guide rail 110 and the machine base 130, and the support rod 140 includes a first support rod 141 and a second support rod 142. By moving the first support rod 141 relative to the second support rod 142, the height of the guide rail 110 relative to the machine base 130 can be precisely adjusted; wherein, the first support rod 141 can move relative to the second support rod 142 under the drive of a motor.
[0037] Since the printhead 121 is mounted on the guide rail 110 along with the moving frame 120, the height of the printhead 121 relative to the machine platform 130 can be adjusted by adjusting the height of the guide rail 110. This ensures that the distance between the printhead 121 and the printing platform 131 is always optimal. When the printhead 121 is printing on displays of different thicknesses, the operator can quickly adjust the height as needed to avoid collisions between the printhead 121 and the display, which could damage the printhead 121 or the display. When no height adjustment is needed, the first support rod 141 can be completely stored in the second support rod 142, reducing space occupation and improving the flexibility and adaptability of the printing equipment 100.
[0038] In addition, the support rod 140 provides additional mechanical support for the guide rail 110, enhancing the connection stability between the guide rail 110 and the machine base 130 and reducing displacement caused by vibration or external force; the support rod 140 can distribute the load on the guide rail 110, ensuring the balanced and stable operation of the entire printing equipment 100.
[0039] Figure 3 This is a schematic diagram of the third embodiment of the inkjet printing equipment of this application, as shown below. Figure 3 As shown, the inkjet printing equipment 100 also includes a housing 150, and the guide rail 110, the movable frame 120 and the printing platform 131 are all disposed inside the housing 150.
[0040] In this embodiment, the guide rail 110, the moving frame 120, and the printing platform 131 are enclosed by an additional housing 150 to prevent operators from accidentally coming into contact with high-speed moving parts or live parts, thereby reducing operational risks.
[0041] Furthermore, the housing 150 can effectively isolate dust, moisture and other pollutants in the external environment, and effectively prevent ink from splashing into the surrounding environment during the printing process, keeping the working area clean, reducing environmental pollution and extending the service life of the equipment.
[0042] Furthermore, a first window 151 is provided on the housing 150, which is used to partially expose the space inside the housing 150.
[0043] By setting a first window 151 on the housing 150, the operator can intuitively observe the working status inside the housing 150, such as the movement of the guide rail 110, the moving frame 120 and the printhead 121, to ensure that the printing process proceeds normally. When the equipment malfunctions, the operator can directly view the status of the internal components through the first window 151 to help quickly locate the problem and make a preliminary diagnosis.
[0044] Figure 4 This is a schematic diagram of the fourth embodiment of the inkjet printing equipment of this application, as shown below. Figure 4 As shown, the inkjet printing equipment 100 also includes a printhead cleaning device 160. The printhead cleaning device 160 is mounted on the machine base 130 and is correspondingly mounted below the guide rail 110. After the printhead 121 finishes printing, the printhead 121 is moved out of the printing platform 131 and moved above the printhead cleaning device 160. The printhead cleaning device 160 is used to clean the residual ink on the printhead 121.
[0045] In this embodiment, a printhead cleaning device 160 is also provided. After the printhead 121 finishes printing, the printhead 121 is moved out of the printing platform 131 and moved above the printhead cleaning device 160 for cleaning.
[0046] The timely cleaning of residual ink on the printhead 121 by the printhead cleaning device 160 can effectively prevent the ink from clogging the nozzle after drying, ensuring that the printhead 121 is always in good working condition. Keeping the printhead 121 clean can reduce friction between the printhead 121 and impurities in the ink, reduce the wear rate of the printhead 121, and extend its service life.
[0047] Since the printhead 121 needs to move from a preset position to the printing platform 131 and align itself with the target area when it first starts working, and it is necessary to ensure that the printhead 121 is aligned with the product to be printed during this process, this application also makes improvements to the printing equipment 100, as follows:
[0048] Figure 5 This is a schematic diagram of the fifth embodiment of the inkjet printing equipment of this application, as shown below. Figure 5 As shown, the movable frame 120 is also equipped with an image detection device 170, which is used to detect whether the printhead 121 is aligned with the product to be printed at a preset position.
[0049] In this embodiment, by setting up an image detection device 170, the relative position of the printhead 121 and the product to be printed can be captured in real time, ensuring that the printhead 121 is accurately aligned with the target area and avoiding printing deviation. The image detection device 170 can be a positioning camera.
[0050] The image detection device 170 detects in real time whether the printhead 121 is aligned with the product to be printed. If it is aligned, printing proceeds normally. If it is not aligned, the image can provide feedback to the operator, allowing the operator to make timely adjustments. This ensures consistent printing quality, reduces product defects caused by alignment errors, and improves the yield.
[0051] Figure 6 This is a schematic diagram of the sixth embodiment of the inkjet printing equipment of this application, as shown below. Figure 6 As shown, a height detection device 180 is also provided on the movable frame 120. The height detection device 180 is used to detect the distance between the printhead 121 and the printing platform 131.
[0052] In this embodiment, a height detection device 180 is also provided on the movable frame 120. The height detection device 180 moves with the movable frame 120 and monitors the distance between the printhead 121 and the printing platform 131 in real time to ensure that the two are kept within the optimal working distance range and avoid printing quality problems caused by the distance being too close or too far.
[0053] Figure 7 This is a schematic diagram of the seventh embodiment of the inkjet printing equipment of this application, as shown below. Figure 7 As shown, the printing equipment 100 also includes an alarm device 190, which is connected to a height detection device 180. When the height detection device 180 detects that the distance between the printhead 121 and the printing platform 131 is less than or greater than a first preset distance, the height detection device 180 transmits the detection signal to the alarm device 190, and the alarm device 190 is in a first state. When the height detection device 180 detects that the distance between the printhead 121 and the printing platform 131 is equal to the first preset distance, the height detection device 180 transmits the detection signal to the alarm device 190, and the alarm device 190 is in a second state.
[0054] The alarm device 190 can display a color or emit an alarm sound. When the alarm device 190 is used to display a color, it can display red when it is in the first state and green when it is in the second state. When the alarm device 190 is used to emit an alarm sound, it can emit an alarm sound when it is in the first state and does not emit a sound when it is in the second state.
[0055] In the printing equipment 100, the height detection device 180 continuously monitors the distance between the printhead 121 and the printing platform 131 and transmits the detection signal to the alarm device 190. The alarm device 190 is connected to the height detection device 180 and triggers different alarm states according to the change in the distance between the printhead 121 and the printing platform 131, so as to ensure that the operator can understand the current working status in a timely manner.
[0056] For example, when the alarm device 190 is an alarm indicator light, when the height detection device 180 detects an abnormal distance (less than or higher than the first preset distance) between the printhead 121 and the printing platform 131, the height detection device 180 transmits the detection signal to the alarm device 190. The alarm device 190 then displays a red indicator light to remind the operator to adjust the height of the printhead 121 in a timely manner to avoid collision between the printhead 121 and the product to be printed on the printing platform 131, which could lead to damage to the printhead 121 or the product to be printed.
[0057] When the height detection device 180 detects that the distance between the printhead 121 and the printing platform 131 is equal to the first preset distance, the alarm device 190 displays green, indicating that the equipment is in the best working state, ensuring the stability and consistency of the printing process; and it can help operators to detect and deal with abnormal spacing problems in a timely manner, shorten the debugging time, and improve production efficiency.
[0058] Figure 8 This is a schematic diagram of an embodiment of the inkjet printing system of this application, as shown below. Figure 8 As shown in the illustration, this application also discloses a printing system 10, including a host computer 200. The printing system 10 further includes the aforementioned printing device 100, and the host computer 200 is connected to the printing device 100. The host computer 200 can be a computer, which connects to the printing device 100 and controls the operation of the printing device 100 through a preset program, thereby enabling the printing device 100 to perform printing operations on the product to be printed.
[0059] It should be noted that the product to be printed in this application can be a display screen, and the printing equipment 100 can be used to print a light-shielding layer in the non-display area of the display screen.
[0060] In the traditional inkjet printing system 10, during the printing process on the display screen, a special photoresist for the light-shielding area needs to be covered on the entire glass substrate, and then the unwanted parts are removed by the exposure equipment, leaving the graphic area that meets the production requirements. The production process is complicated, the production efficiency is low, and raw materials are wasted.
[0061] Based on the above problems, this application improves the printing equipment 100 in the printing system 10 by integrating the printhead 121 and the curing device 123 onto the same movable frame 120, which moves on the guide rail 110. This allows the printhead 121 to move along a predetermined path under precise control, ensuring high precision and consistency of the printed pattern. While the printhead 121 is printing on the product, the curing device 123 immediately follows the printhead 121 and cures the area just printed. There is no need to wait for the ink to dry naturally; curing can be performed immediately after ink printing, ensuring that the ink does not spread or deform, thus guaranteeing printing quality and forming a predetermined pattern on the product. This eliminates the need for processes such as covering and exposing the printing material, reducing manual intervention, lowering operational difficulty and error rate, effectively improving the production efficiency of the product, saving costs, and thus improving the working and production efficiency of the printing system 10.
[0062] It should be noted that the inventive concept of this application can form many embodiments, but due to the limited space of the application documents, they cannot all be listed. Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effect will be enhanced.
[0063] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
