[0045] Inkjet printing is an important research direction in the field of display technology. It aims to achieve efficient and low-cost fabrication of various functional layers through inkjet printing technology. Compared with traditional vacuum evaporation technology, inkjet printing technology can significantly reduce material consumption and production costs. Inkjet printing technology is a non-contact patterning technology that can precisely spray ink droplets onto designated positions on the substrate to achieve high-resolution patterning.

[0046] However, current drying structures are inefficient, and liquid materials remain on the substrate for a long time, forming a wet layer. This not only prolongs the drying time but also makes the oil easily spread due to slight contact or airflow. Therefore, existing technologies need to be improved and developed.

[0047] As attached Figure 1 To be continued Figure 9 As shown, this application provides a liquid supply device that adopts the following technical solution:

[0048] A liquid supply device includes a motion component, a control component 100, and a liquid supply component 200. The liquid supply component 200 is connected to the motion component, and the control component 100 is connected to the motion component. The control component 100 drives the motion component to move the liquid supply component 200. The liquid supply component 200 includes a nozzle 1 and a heating element 2 disposed on the nozzle 1. This application improves the drying rate of the material by providing the heating element 2 on the nozzle 1 to preheat the liquid material during printing.

[0049] It is understandable that the liquid material can be a solution containing display functional materials, which is dried to form the various functional layers in the display device.

[0050] Furthermore, the motion assembly includes a main motion assembly 300 and an auxiliary motion assembly 400, the main motion assembly 300 and the auxiliary motion assembly 400 being respectively connected to the liquid supply assembly 200;

[0051] The control component 100 is connected to the main motion component 300 and is used to drive the liquid supply component 200 to move.

[0052] The printhead 1 is positioned by the main motion component 300 and the auxiliary motion component 400, which facilitates the vertical adjustment of the printhead 1, improves the stability of the adjustment, avoids excessive swaying angle when the printhead 1 moves up and down, and improves liquid supply and printing accuracy.

[0053] Furthermore, the main motion component 300 includes a wheel structure 3 and a cable 4, one end of which is connected to the liquid supply component 200, and the other end is wound around the wheel structure 3; and / or,

[0054] The auxiliary motion component 400 includes several fixed rods 5, and also includes a sliding member 6, a traction member 61 and a connecting member 62;

[0055] The sliding member 6 is slidably disposed on the fixed rod 5, the connecting member 62 is disposed on the liquid supply assembly 200, and the two ends of the traction member 61 are respectively connected to the sliding member 6 and the connecting member 62.

[0056] During adjustment, the sliding member 6 slides up and down on the fixed rod 5 to assist in adjusting the nozzle 1, making it convenient to adjust the vertical position of the nozzle 1. At the same time, the traction member 61 is hinged to the sliding member 6 and the connecting member 62 respectively, so that the sliding member 6 can slide up and down on the fixed rod 5 during vertical position adjustment.

[0057] In one embodiment, the two ends of the traction member 61 are hinged to the sliding member 6 and the connecting member 62, respectively.

[0058] Furthermore, the control component 100 includes a first motor (not shown in the figure), the output end of which is connected to the rotating wheel structure 3 to drive the rotating wheel structure 3 to rotate.

[0059] The rotating wheel structure 3 can retract the cable 4, and at the same time, when the first motor controls the cable 4 to drive the nozzle 1 to adjust its position up and down, it can continuously and smoothly supply the cable 4, which facilitates the up and down movement of the cable 4, increases the range of up and down movement of the nozzle 1, and avoids problems such as the cable 4 getting tangled or insufficient supply of the cable 4 causing uneven up and down adjustment.

[0060] Furthermore, the number of the traction members 61 corresponds to the number of the fixing rods 5.

[0061] For example, there are 6 fixed rods 5 and 61 traction members. One sliding member 6 is connected to 2 fixed rods 5, that is, there are 3 sliding members 6. The connecting member 62 is set to one. The sliding member 6 has a through hole 63 sleeved on the fixed rod 5, which can improve the sliding stability of the sliding member 6. At the same time, the array of fixed rods 5 is respectively on the base 7, which facilitates the fixation of the printhead 1 in multiple directions, further improving the stability of the movement of the printhead 1, so that the ink can be accurately deposited on the substrate or base plate, thereby improving the printing accuracy.

[0062] Furthermore, the sliding member 6 and the connecting member 62 are each provided with a connector 60, and both ends of the traction member 61 are respectively provided with connecting sleeves 611 for connecting with the sliding member 6 and the connecting member 62. The connecting sleeves 611 are fitted over the connectors 60. The structure is simple and easy to connect, providing convenient and stable conditions for adjusting the vertical position of the nozzle 1.

[0063] Furthermore, the nozzle 1 has a liquid outlet 11, the heating element 2 is located at the end of the nozzle 1 away from the liquid outlet 11, and one end of the cable 4 is connected to the heating element 2.

[0064] The heating wire preheats the liquid material during printing. The preheated liquid material is then ejected from the outlet 11, increasing both the fluidity of the liquid material and the speed of solvent molecule movement, thus accelerating its evaporation and improving the drying rate. This, in turn, enhances film uniformity and quality. Furthermore, after printing, heating or vacuum drying of the display panel can be omitted, simplifying the process, improving printing efficiency, and reducing processing costs. Simultaneously, the cable 4 can be electrically connected to the heating element 2 to control its heating, and it can also be fixedly connected to the printhead 1, allowing for vertical adjustment of the printhead 1 via the first motor. This facilitates printing from different positions to meet various printing needs, increasing printing versatility. The liquid material can be precisely deposited on the substrate or base plate, improving liquid supply and printing accuracy.

[0065] Furthermore, the cable 4 is configured as a power supply cable, which can not only supply power to the nozzle 1, but also form a protective shell that is sturdy and not easily stretched. The nozzle 1 connected to it can be adjusted up and down by pulling the cable 4. This cleverly utilizes the characteristics of the power supply cable to reduce the number of control components and lower costs.

[0066] Furthermore, the heating element 2 includes a heating wire, which is arranged around the end of the nozzle 1 away from the liquid outlet 11; and / or

[0067] The liquid supply device further includes a liquid storage chamber, which is connected to the end of the nozzle 1 away from the liquid outlet 11.

[0068] The heating wire can preheat the liquid material during printing. The preheated liquid material is then sprayed onto the substrate surface, increasing the fluidity of the liquid material and the movement speed of solvent molecules, thereby accelerating their evaporation from the liquid material and improving the drying rate of the liquid material. This, in turn, improves the uniformity and quality of film formation. Furthermore, after printing, the heating or vacuum drying of the display panel can be omitted, simplifying the process, thereby improving printing efficiency and reducing processing costs.

[0069] Furthermore, it also includes a fixing component 500, on which the motion component and the control component 100 are disposed.

[0070] Furthermore, the fixing component 500 includes a base 7 and a top plate 71 disposed opposite to each other;

[0071] The main motion assembly 300 and the control assembly 100 are mounted on the top plate 71, and the two ends of the fixing rod 5 are respectively connected to the base 7 and the top plate 71; and / or

[0072] The fixing assembly 500 further includes a side plate 72, the two ends of which are respectively connected to the base 7 and the top plate 71; and / or

[0073] The base 7 is also provided with a printing platform 73.

[0074] When in use, the glass substrate or substrate to be printed can be placed on the printing platform 73 for easy printing. At the same time, the base 7 lowers the center of gravity, reduces the tilt and vibration of the printer during operation, further enhances the stability during printing, reduces errors during printing, ensures print quality, and improves print accuracy.

[0075] Furthermore, the fixing rod 5 is also fixedly connected to the side plate 72 via the fixing member 74. In addition to being fixed to the base 7 and the top plate 71, the fixing member 74 can further tighten the fixing rod 5 to prevent it from shaking, thereby further improving the stability of the nozzle 1's movement and allowing the liquid material to be accurately deposited on the substrate or base plate, thus improving printing accuracy.

[0076] Furthermore, the rotating wheel structure 3 is mounted on the top plate 71, which facilitates the winding of the cable 4 and provides convenience for the up-and-down movement of the cable 4 when the first motor controls the cable 4 to drive the nozzle 1 to adjust its position. This increases the range of up-and-down movement of the nozzle 1 and avoids problems such as the cable 4 getting tangled or insufficient cable 4 supply causing uneven up-and-down adjustment.

[0077] Furthermore, the control component 100 also includes a controller 8, which is connected to the main motion component 300;

[0078] The controller 8 includes a second motor 81, a driven wheel 82, and a driving wheel 83. The output end of the second motor 81 is connected to the driving wheel 83, and the cable 4 is disposed between the driven wheel 82 and the driving wheel 83.

[0079] During printing, the second motor 81 rotates, driving the drive wheel 83 on the output shaft of the second motor 81 to rotate, causing the drive wheel 83 to drive the cable 4 to move up and down, thereby assisting the main motion component 300 in controlling the printhead 1 to adjust its position up and down, so that the printhead 1 can print in different positions to adapt to different printing needs, improve printing diversity, and allow ink to be accurately deposited on the substrate or base plate, further improving printing accuracy.

[0080] Furthermore, the control component 100 and the controller 8 are respectively mounted on the fixing component 500 for easy fixation; the cable 4 is disposed between the driven wheel 82 and the driving wheel 83. One end of the cable 4 passes through the controller 8 and is connected to the nozzle 1, further improving the stability of the nozzle 1 in adjusting its vertical position.

[0081] Furthermore, the controller 8 also includes an adjustment device for adjusting the distance between the driven wheel 82 and the driving wheel 83;

[0082] The adjusting device includes a first clamping member 84, a second clamping member 85, and an adjusting member 86. One end of the first clamping member 84 is rotatably mounted on the fixing component 500, and the second clamping member 85 is fixedly mounted on the fixing component 500. The driven wheel 82 is rotatably mounted on the end of the first clamping member 84 that is rotatably connected to the fixing component 500. The adjusting member 86 connects the other end of the first clamping member 84 and the second clamping member 85.

[0083] By adjusting the distance between the driven wheel 82 and the driving wheel 83, the clamping force of the driven wheel 82 and the driving wheel 83 on the cable 4 can be adjusted to accommodate different sizes of the cable 4. This facilitates the driving wheel 83 to drive the cable 4 and the driven wheel 82 to assist in its movement. At the same time, the controller 8 can limit the movement of the cable 4 to prevent excessive swaying angle when the cable 4 moves up and down, which could cause the printhead 1 to shake and affect printing accuracy.

[0084] Furthermore, one end of the first clamping member 84 is rotatably mounted on the top plate 71, and the second clamping member 85 is fixedly mounted on the top plate 71. When the adjusting member 86 is turned, the first clamping member 84 rotates around one end, thereby causing the other end of the first clamping member 84 to move closer to or further away from the second clamping member 85. This adjusts the distance between the driven wheel 82 and the driving wheel 83, and adjusts the clamping force of the driven wheel 82 and the driving wheel 83 on the cable 4, adapting to different sizes of cables 4. The structure is simple and easy to adjust. It also facilitates the driving wheel 83 to drive the cable 4 and the driven wheel 82 to assist in moving the cable 4. In addition, the controller 8 can limit the movement of the cable 4 to prevent excessive swaying angle when the cable 4 moves up and down, which could cause the printhead 1 to shake and affect printing accuracy.
