Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a printing device. Background Technology

[0002] In the screen printing process of solar glass deep processing, PVC foam board is usually attached to the back of the screen as a backing plate. This serves to balance the printing blade pressure and prevent the printing edges from directly rubbing against the glass, which could damage or deform the screen. However, attaching the PVC foam board to the back of the screen fixes it in a specific position, making it unusable as the screen's lifespan ends, resulting in non-recyclability and resource waste. Furthermore, the fixed position of the backing plate cannot be adjusted to adapt to changes in glass size, and the position of the backing plate cannot be well matched with the printing blade for screen movement, resulting in low flexibility and limited effectiveness.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] In view of this, please refer to Figures 1 to 4 This invention provides a printing apparatus 100, which includes a cutting tool assembly 110, a screen assembly 120, and a support assembly 130. The printing blade 111 in the cutting tool assembly 110 is configured to move along a first direction X to apply pressure to a printing screen 122 to adhere it to a workpiece and transfer the pattern. The screen assembly 120 includes a mounting frame 121 and a printing screen 122, wherein the printing screen 122 is detachably mounted to the mounting frame 121 and can contact the workpiece surface under the action of the printing blade 111, thereby allowing the pattern on the printing screen 122 to be accurately imprinted on the workpiece surface.

[0042] A support assembly 130 is disposed on the side of the screen printing assembly 120 opposite to the cutter assembly 110, and includes a pad module 131 and a support base 132. The pad module 131 further includes a first pad group 1311 and a second pad group 1312, which are spaced apart at opposite ends of the support base 132 along a first direction X. The support base 132 is used to support the workpiece, and the workpiece is located between the first pad group 1311 and the second pad group 1312. By moving the first pad group 1311 and / or the second pad group 1312 relative to the support base 132 along the first direction X, the position of the workpiece can be adjusted, ensuring accuracy and stability during the printing process, thereby improving printing quality and efficiency. Furthermore, this application provides a flexible and adjustable support system; the movable design of the first pad group 1311 and / or the second pad group 1312 allows the printing apparatus 100 to adapt to workpieces of different sizes and shapes, thereby improving the applicability of the printing apparatus 100.

[0043] In some embodiments, the printing apparatus 100 is further provided with an automatic adjustment mechanism configured to drive the first pad group 1311 and the second pad group 1312 to move, thereby enabling the first pad group 1311 and the second pad group 1312 to automatically adjust their positions according to the actual size of the workpiece, further improving the automation level and applicability of the equipment.

[0044] Please see Figure 2 and Figure 3 In some embodiments, the pad module 131 further includes a drive group 1313 connected to the first pad group 1311 for driving the first pad group 1311 to move relative to the support base 132 in a first direction X. Specifically, the drive group 1313 includes a first drive wheel 1313a, a first transmission member 1313b, and a first drive member 1313c. The first transmission member 1313b connects the first drive wheel 1313a to the first drive member 1313c. When the first drive member 1313c is activated, it drives the first transmission member 1313b to run, thereby causing the first drive wheel 1313a to rotate. The first pad group 1311 includes a first pad 1311a and a first extension 1311b, wherein the first extension 1311b is fixed to the side of the first pad 1311a away from the second pad group 1312 and is movably connected to the first drive wheel 1313a. When the first drive wheel 1313a rotates, it pushes the first extension 1311b to move, which in turn causes the first pad 1311a to move relative to the support 132. This not only simplifies the mechanical structure but also ensures the accuracy and reliability of the movement.

[0045] Similarly, the drive assembly 1313 is also connected to the second pad assembly 1312, which drives the second pad assembly 1312 to move relative to the support base 132 in the first direction X. Specifically, the drive assembly 1313 includes a second drive wheel, a second transmission component, and a second drive component. The second transmission component connects the second drive wheel to the second drive component. When the second drive component is activated, it drives the second transmission component to run, thereby causing the second drive wheel to rotate. The second pad assembly 1312 includes a second pad 1312a and a second extension 1312b, wherein the second extension 1312b is fixed to the side of the second pad 1312a away from the first pad assembly 1311 and is movably connected to the second drive wheel. When the second drive wheel rotates, it pushes the second extension 1312b to move, thereby causing the second pad 1312a to move relative to the support base 132. This allows for simultaneous adjustment of the positions of the pad assemblies on both sides, more flexibly adapting to various complex printing needs and enhancing the versatility of the equipment.

[0046] In some embodiments, the first pad assembly 1311 is configured to move relative to the support base 132 under the drive of the drive assembly 1313, while the second pad assembly 1312 is fixedly connected to the support base 132. Thus, by moving the first pad assembly 1311 closer to or away from the second pad assembly 1312, workpieces of different sizes can be fitted. Similarly, the second pad assembly 1312 can be configured to move relative to the support base 132 under the drive of the drive assembly 1313, while the first pad assembly 1311 is fixedly connected to the support base 132. By driving the second pad assembly 1312 closer to or away from the first pad assembly 1311, workpieces of different sizes can be fitted.

[0047] In a further embodiment, the pad module 131 includes a plurality of first pad groups 1311, and the drive group 1313 is correspondingly configured with a plurality of first drive wheels 1313a, each first drive wheel 1313a being connected to a corresponding first pad group 1311. The first transmission member 1313b not only connects all the first drive wheels 1313a, but also drives each first drive wheel 1313a to rotate synchronously under the drive of the first drive member 1313c. This ensures that all first pad groups 1311 move along the first direction X at the same speed and direction, thereby providing a stable and uniform pressure distribution environment for the workpiece to be printed, avoiding printing quality problems caused by uneven pressure.

[0048] It should be noted that the multiple first pad groups 1311 work together to ensure that the workpiece surface is subjected to balanced pressure throughout the printing process, which helps to improve printing accuracy and consistency. Furthermore, this synchronous motion mechanism simplifies the equipment operation process, reduces the skill requirements for operators, and also reduces equipment maintenance costs, demonstrating significant technological advancement and practical value.

[0049] Please see Figure 3In some embodiments, the first pad assembly 1311 further includes a first positioning member 1311c. The first positioning member 1311c is connected between the first pad 1311a and the first extension 1311b, and protrudes from the first extension 1311b along the second direction Y (perpendicular to the first direction X). One side of the first positioning member 1311c in the first direction X is detachably abutted against one end of the support base 132 along the first direction X. The provision of the first positioning member 1311c helps to improve the connection strength between the first extension 1311b and the first pad 1311a, and avoids the situation where the extension 1311b jumps during the movement of the first drive wheel 1313a driving the first extension 1311b, causing the first extension 1311b to disengage from the first drive wheel 1313a, thus effectively improving the connection reliability between the first extension 1311b and the first drive wheel 1313a. The first positioning element 1311c can also play a positioning role during the movement of the first pad 1311a along the first direction X, so as to prevent the first pad 1311a from overtraveling.

[0050] Specifically, when the printing apparatus 100 is adjusted or ready to start printing, the first positioning member 1311c ensures that the first pad assembly 1311 maintains precise positioning during movement relative to the support base 132. For example, when printing on workpieces of different sizes, during the adjustment of the position of the first pad assembly 1311, as the first pad 1311a moves along the first direction X toward the second pad 1312a, the first positioning member 1311c, with one end near the first pad 1311a abutting against the support base 132, moves the first pad 1311a to its final position. That is, the first positioning member 1311c can accurately define its final position, ensuring precise contact and flatness between the workpiece surface and the printing screen 122. This not only improves the clarity and accuracy of the printed pattern but also reduces printing quality problems caused by positional deviations, thereby improving overall work efficiency and product quality.

[0051] Similarly, the second pad assembly 1312 is equipped with a second positioning member structure similar to the first positioning member 1311c. Therefore, more precise position control can be achieved when handling both large and small workpieces, further improving the flexibility and applicability of the equipment.

[0052] In some embodiments, the printing apparatus 100 further includes a conveying assembly, and the support base 132 includes a plurality of spaced-apart support frames 1321. The conveying assembly is mounted within an accommodating space 1322 defined by the plurality of spaced-apart support frames 1321. The conveying assembly is configured to move a workpiece thereon, thereby enabling an automated or semi-automated workpiece conveying process.

[0053] For example, in actual operation, a workpiece can enter from one port of the printing device 100 via a conveyor assembly and move along a predetermined path to another port. During this process, the workpiece can smoothly transition between different working areas, such as moving from a preparation area to a printing area, and then to a drying area. This design not only simplifies manual operation and reduces the possibility of human error, but also significantly improves production efficiency, especially in high-volume production scenarios.

[0054] To further enhance the functionality and adaptability of the printing apparatus 100, an intelligent control system can be integrated into the conveying assembly, enabling it to automatically adjust speed and path according to different workpiece types and sizes. Furthermore, sensor technology can be introduced to monitor the position and status of workpieces in real time, ensuring optimal processing results for each workpiece. In this way, even when faced with complex production demands, the printing apparatus 100 can flexibly respond and meet diverse market needs.

[0055] In some embodiments, the first pad assembly 1311 and / or the second pad assembly 1312 are movable relative to the support 132 along a first direction X and abut against both ends of the workpiece along the first direction X. This ensures that the surface of the workpiece facing the printing screen 122 remains flush with the surfaces of the first pad assembly 1311 and the second pad assembly 1312 facing the printing screen 122.

[0056] During the printing operation, when the workpiece is placed on the support 132 and positioned between the first pad group 1311 and the second pad group 1312, the workpiece can be precisely aligned by adjusting the position of the first pad group 1311 and / or the second pad group 1312, ensuring that its surface is in close contact with the printing screen 122. This guarantees that the pattern can be accurately transferred to the workpiece surface. This structure helps eliminate printing quality problems caused by uneven surfaces, such as blurred patterns or positional misalignment. Furthermore, this design improves the adaptability of the printing apparatus 100, enabling it to handle workpieces of different sizes and shapes without the need to replace specialized adapter parts.

[0057] To further enhance the flexibility of the printing apparatus 100, a fine-tuning mechanism could be added to the first pad group 1311 and the second pad group 1312, allowing users to make subtle adjustments according to specific workpiece requirements to achieve optimal printing results. Additionally, an automatic calibration system could be introduced, using sensors to detect the workpiece's position and surface condition, and automatically adjusting the position of the pad groups to achieve intelligent operation.

[0058] Please see Figure 1 and Figure 2In some embodiments, the cutting tool assembly 110 includes not only a printing blade 111, but also a first track 112 extending along a first direction X. It should be noted that the first track 112 may include multiple tracks to improve the movement stability of the printing blade 111. The printing blade 111 is connected to the first track 112 and configured to move along the first track 112. This allows the printing blade 111 to move freely in the first direction X, thereby covering a wider working area and meeting the printing needs of different types of workpieces.

[0059] For example, when printing on a large workpiece, the printing blade 111 can complete the pattern printing task on the entire surface of the workpiece by moving along the first track 112. This not only improves work efficiency but also ensures the consistency and continuity of the pattern. At the same time, by adjusting the speed and pressure parameters of the printing blade 111 on the first track 112, the printing quality can be optimized according to different materials and pattern requirements.

[0060] To further enhance functionality, multiple printing blades 111 can be installed on the first track 112. Each blade can operate independently according to a set program, enabling simultaneous printing of multi-color or multi-layer patterns, greatly improving the functionality and production efficiency of the printing device 100. Furthermore, a precision adjustment device can be equipped on the first track 112, allowing users to precisely control the position and speed of the printing blades 111 according to specific needs, ensuring that each print achieves the desired effect.

[0061] Please see Figure 2 In some embodiments, the mounting bracket 121 includes a crossbeam 123 disposed opposite to the first direction X, and also includes a second track 124 extending along the first direction X. The crossbeam 123 is connected to the second track 124, and the crossbeam 123 is movable along the second track 124. This allows the user to adjust the position and size of the printing screen 122 according to actual needs, thereby accommodating workpieces of different specifications.

[0062] For example, when handling larger workpieces, the operator can easily move the crossbeam 123 along the second track 124 to expand the effective coverage of the printing screen 122. This not only improves the flexibility of the equipment but also ensures consistent printing quality. Furthermore, by precisely controlling the movement distance of the crossbeam 123, accurate printing on specific areas can be achieved, meeting the demands of high-precision printing.

[0063] To further enhance the functionality of the equipment, scale markings or an automatic positioning system can be added to the second track 124, making each adjustment more accurate and faster. Additionally, sensors can be equipped on the crossbeam 123 to monitor its position changes in real time, ensuring optimal printing performance under all conditions. This allows the printing device 100 to be suitable for production environments requiring frequent changes in workpiece size, significantly improving work efficiency and ease of operation.

[0064] In some embodiments, the mounting bracket 121 includes a first bracket and a second bracket, which are arranged opposite to each other in a direction from the cutter assembly 110 to the support assembly 130. The printing screen 122 is mounted between the first and second brackets and can be disassembled and reinstalled as needed. Simultaneously, the first and second brackets are configured to move relative to each other to facilitate easier installation and removal of the printing screen 122.

[0065] Specifically, during routine maintenance or replacement of the printing screen 122, operators can quickly complete the replacement process by adjusting the distance between the first and second frames. This significantly reduces downtime and improves production efficiency. Furthermore, because the printing screen 122 is detachable, a suitable screen can be selected for different printing tasks, increasing the equipment's application range.

[0066] To further enhance the user experience, locking mechanisms can be added to both the first and second frames to ensure their stability during use and prevent print quality issues caused by accidental movement. Additionally, an electric adjustment device can replace manual adjustment, making it simpler and faster to adjust the distance between the first and second frames. This design is particularly advantageous for work scenarios requiring frequent changes to the printing screen 122, saving time and reducing labor intensity. Simultaneously, this makes the printing device 100 more suitable for large-scale production line applications, improving overall production efficiency.

[0067] Specifically, please refer to Figure 2 and Figure 3The support assembly 130 also includes multiple fixing members 133, multiple transmission teeth 134, and a throttle 135. The throttle 135 can be used to fine-tune the position of the first pad 1311a relative to the support frame 1321. Part of the fixing members 133 are mounted on the support frame 1321, and the first drive wheel 1313a is mounted on the support frame 1321 via these fixing members 133. The first transmission member 1313b can be a chain or belt, etc., and is connected to the transmission teeth 134. The throttle 135 is inserted into the transmission teeth 134, the first drive wheel 1313a, and the fixing members 133. Another part of the fixing members 133 is mounted on the other end of the support frame 1321 in the vertical direction. The first drive member 1313c is mounted on the fixing member 133 and connected to another part of the transmission teeth 134, which are mounted on one end of the first transmission member 1313b in the vertical direction. Therefore, when the first driving member 1313c rotates, the transmission gear 134 connected to the first driving member 1313c rotates accordingly, thereby driving the first transmission member 1313b to move. The first transmission member 1313b further drives the transmission gear 134 mounted on the throttle 135 to rotate, and thus the first drive wheel 1313a rotates accordingly, thereby driving the first extension member 1311b to move.

[0068] In some embodiments, the throttle 135 can also be used to drive the first transmission member 1313b to rotate. The first transmission member 1313b transmits the driving force to the first extension member 1311b and the first drive member 1313c. Thus, the first extension member 1311b moves under the action of the driving force, while the first drive member 1313c drives each of the first transmission members 1313b connected thereto to move under the action of the driving force, thereby causing each of the first drive wheels 1313a connected to each of the first transmission members 1313b to rotate, thereby causing each of the first extension members 1311b to move.

[0069] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0070] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
