Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to a printer. Background Technology

[0002] With the continuous development of digital printing technology, UV printers (Ultraviolet LED Inkjet Printers) are high-tech, plate-free color digital printing machines. They boast high precision, high efficiency, and wide material adaptability, finding widespread application in advertising production, art reproduction, and industrial manufacturing signage. In practical applications, to achieve high-precision printing results, the motion mechanisms of UV printers typically employ a precision-fit design to ensure the stability and accuracy of each component during printing. While this tight-fitting, non-disassembly method guarantees print quality, it also significantly limits the printer's application scenarios. Utility Model Content

[0065] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0066] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0067] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0068] First Embodiment

[0069] like Figures 2-6 As shown, a printer is designed to meet various needs such as planar inkjet printing and 3D inkjet printing. Its flexible modular design enables adaptability to a wide range of application scenarios. The printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4.

[0070] The support base 1 serves as the basic structure, providing a stable support platform for the entire printer. The design of the support base 1 must consider load-bearing capacity and stability to ensure that the printer remains stable under various operating conditions.

[0071] The motion device 2 includes a motion seat 21, which is movably connected to the support base 1, such that the motion seat 21 can move along the first direction of the printer (see reference). Figure 3 The Y-axis (as shown) reciprocates, facilitating inkjet printing of the workpiece on the printing platform.

[0072] The printing platform 3 is mounted on the motion base 21 and is detachably connected to it, allowing for disassembly and reassembly to suit different application scenarios and improve printing range and flexibility. The printing platform 3 is a fixture for placing the workpiece to be printed. It should be noted that this solution does not limit the specific structure of the printing platform 3. The printing platform 3 can be a regular structure, such as a flat plate, with a flat surface for placing the workpiece; it can also be an irregular structure, such as a rotating body, used to hold and rotate a cup, or have irregular surfaces for placing workpieces of different shapes.

[0073] The locking device 4 enables the stable installation and convenient disassembly of the printing platform 3 on the motion seat 21. The locking device 4 includes, for example, a first locking part 41 and a second locking part 42, with the first locking part 41 having a locking groove 411. In one embodiment, the first locking part 41 is disposed on the motion seat 21, and the second locking part 42 is disposed on the printing platform 3. In another embodiment, the first locking part 41 is disposed on the printing platform 3, and the second locking part 42 is disposed on the motion seat 21. This embodiment is explained using the example of the second locking part 42 being disposed on the printing platform 3 and the first locking part 41 being disposed on the motion seat 21.

[0074] When the printing platform 3 is installed onto the motion base 21, part of the structure of the second locking part 42 can be accommodated in the locking groove 411 to facilitate the locking state of the locking device 4. The first locking part 41 is configured to rotate relative to the second locking part 42, such that the locking device 4 is in a locked state that fixes the printing platform 3 to the motion base 21, or in a released state that unlocks the printing platform 3 from the motion base 21. In the released state, the printing platform 3 and the motion base 21 can be separated.

[0075] In one embodiment, the first locking part 41 and the second locking part 42 are threadedly connected. Part of the structure of the second locking part 42 is accommodated in the locking groove 411 of the first locking part 41. The first locking part 41 rotates relative to the second locking part 42 so that the locking device 4 is in a locked state that fixes the printing platform 3 and the motion seat 21, or in a released state that unlocks the printing platform 3 and the motion seat 21.

[0076] In one embodiment, the first locking part 41 is hinged to the motion seat 21. One end of the first locking part 41 is rotatably connected to the motion seat 21, and the other end is detachably connected to the motion seat 21. When it is necessary to fix the printing platform 3 to the motion seat 21, the other end of the first locking part 41 is first separated from the motion seat 21, and part of the structure of the second locking part 42 is accommodated in the locking groove 411 of the first locking part 41. Then, the first locking part 41 is rotated so that the other end of the first locking part 41 is fixedly connected to the motion seat 21, thereby limiting the second locking part 42 to the locking groove 411.

[0077] In this embodiment, the printing platform 3 is located on the side of the motion base 21 away from the support base 1, and is separable from the motion base 21 by a locking device 4. Specifically, the locking device 4 includes a first locking part 41 and a second locking part 42. The first locking part 41 rotates relative to the second locking part 42, switching between a locked and a released state. This achieves a detachable connection between the printing platform 3 and the motion device 2, meeting the needs of different application scenarios, improving the printer's flexibility and applicability, and increasing its utilization rate. Furthermore, the motion device 2 and the printing platform 3 are assembled and connected. By rotating the first locking part 41, the relative positions of the first locking part 41 and the second locking part 42 are changed, thereby achieving the locking or releasing state of the locking device 4. This achieves quick disassembly or quick assembly, effectively improving installation efficiency.

[0078] In this embodiment, the first locking part 41 includes a locking wheel 413, which is rotatably connected to the motion seat 21. The locking wheel 413 is provided with a locking groove 411, which is used to accommodate part of the structure of the second locking part 42.

[0079] First Example

[0080] The locking groove 411 is, for example, an arc-shaped groove, and the second locking part 42 is, for example, an arc-shaped body. When the second locking part 42 rotates relative to the first locking part 41, the arc-shaped groove corresponds to the arc-shaped body, allowing the arc-shaped body to be inserted into the arc-shaped groove, thereby achieving a locking state between the first locking part 41 and the second locking part 42; conversely, by moving the arc-shaped body out of the arc-shaped groove, a releasing state between the first locking part 41 and the second locking part 42 can be achieved.

[0081] In operation, the first locking part 41 can rotate relative to the second locking part 42, causing the arc-shaped body to insert or move out of the corresponding arc-shaped groove, thus quickly locking or releasing the printing platform 3 and the motion seat 21. This simple operation method eliminates the need for complex tools or cumbersome steps, greatly improving the efficiency of printer installation and disassembly and saving time.

[0082] This design allows a single person to easily assemble and disassemble the printing platform 3. When it is necessary to frequently change the printing platform to adapt to different printing tasks, the operator can quickly and independently complete the operation without the assistance of others, thus improving the autonomy and flexibility of the work.

[0083] When the arc-shaped body is inserted into the arc-shaped groove, the arc-shaped structure between the two can fit tightly together, forming a large contact area and friction. This tight fit can effectively prevent the printing platform 3 from loosening or shaking during the printing process, ensuring the accuracy and quality of the print. Even when the printer is moving at high speed or subjected to large external forces, the locking device 4 can ensure that the printing platform 3 and the motion seat 21 maintain a relatively stable connection.

[0084] The curved design better adapts to various forces and vibrations generated during the printing process. Under different printing tasks and environmental conditions, the locking device 4 can provide reliable locking force, ensuring stable printer operation and reducing printing failures or quality problems caused by loose printing platform 3.

[0085] This locking mechanism allows the printer to quickly adapt to different application scenarios. For example, in different printing scenarios, it may be necessary to change to a different size or material of the printing platform 3. Through this locking device 4, operators can quickly disassemble and install different types of printing platforms 3 to meet diverse printing needs. At the same time, in scenarios with high printing accuracy requirements, reliable locking performance can also ensure print quality.

[0086] As a crucial module of the printer, the printing platform 3, through this convenient locking mechanism, can be easily combined and replaced with other modules. In the future, if functional expansion or upgrades to the printer are needed, only the corresponding printing platform module needs to be replaced, without requiring large-scale changes to the entire printer, providing strong support for the modular design of printers.

[0087] Second example

[0088] The locking groove 411 is, for example, circular, and the locking wheel 413 has a notch 412 communicating with the locking groove 411. Part of the structure of the second locking part 42 can pass through the notch 412 and enter the locking groove 411. At this time, by rotating the first locking part 41, the relative position of the first locking part 41 and the second locking part 42 is changed, thereby realizing the locking state or the releasing state of the locking device 4.

[0089] For example, the relative position between the notch 412 and the second locking part 42 changes, that is, there is a first relative position and a second relative position between the notch 412 and the second locking part 42. When the notch 412 faces upward, the first relative position between the notch 412 and the second locking part 42 is formed. When the notch 412 is offset from the above position, that is, when it is in other positions, it can be regarded as the second relative position between the notch 412 and the second locking part 42. Since the printing platform 3 is along the vertical direction of the printer (refer to...), Figure 3 The Z-axis shown is installed or removed. Therefore, as long as the notch 412 is offset from the vertical position, it can form a blockage on the second locking part 42, and the second locking part 42 cannot be disengaged from the locking groove 411.

[0090] When the notch 412 and the second locking part 42 are in the first relative position, that is, when the notch 412 faces upward, the locking device 4 is in the released state, which allows for easy disassembly or installation of the printing platform 3. When the notch 412 and the second locking part 42 are in the second relative position, the locking device 4 is in the locked state. The notch 412 and the locking groove 411 form an arc-shaped plate for the first locking part 41, which can constrain the second locking part 42, so that the printing platform 3 is stably installed on the motion seat 21.

[0091] The locking groove 411 is the area inside the first locking part 41 that mates with the locking shaft 422, and its shape, size, and position are matched to the locking shaft 422. For example, the locking groove 411 may be eccentrically circular, such that the distance between the center position and the inner wall of the locking groove 411 varies. The eccentric design can be achieved by utilizing the different thicknesses of the arc-shaped plate, thereby changing the distance between the center position and the inner wall of the locking groove 411. For example, the two sides of the notch 412 are the starting ends, and the position opposite the notch 412 is the ending end; the thickness of the arc-shaped plate gradually increases from the starting end to the ending end. When the locking device 4 is in the released state, the notch 412 faces upward, and there is a second distance between the second locking part 42 and the radial inner wall of the locking groove 411. When the locking device 4 is in the locked state, its first locking part 41 can rotate 180° so that the notch 412 faces downward. At this time, the second locking part 42 can abut against the inner wall of the locking groove 411. There is a first distance between the second locking part 42 and the radial inner wall of the locking groove 411 to improve the stability during locking. The first distance is smaller than the second distance.

[0092] The first locking part 41 is disposed within the motion base 21, which has a first clearance through hole 212. This structural design has multiple advantages. On the one hand, the first clearance through hole 212 provides clearance space for the second locking part 42, ensuring that the second locking part 42 can smoothly pass through the notch 412 to achieve locking and releasing functions. On the other hand, placing the first locking part 41 within the motion base 21 avoids its direct exposure to the external environment, effectively preventing dust, debris, and other contaminants from corroding and damaging the first locking part 41, thus extending the service life of the locking device 4. Simultaneously, this design also improves the overall flatness of the printer, making the printer more stable during operation and reducing vibration and noise caused by structural unevenness.

[0093] The locking device 4 switches between locking and releasing states by rotating the first locking part 41 to change its relative position with the second locking part 42. When the notch 412 faces the side closest to the printing platform 3 and is in the first relative position, the locking device 4 is in the released state. At this time, the printing platform 3 can be easily disassembled or installed without complicated tools or cumbersome steps, greatly improving operational efficiency. This simple and convenient operation method reduces the professional skills required of operators and reduces operation time and labor costs.

[0094] The locking groove 411 precisely matches the second locking part 42, and the locking groove 411 can be designed as an eccentric circle, achieving the eccentric design through the variation in thickness of the arc plate. Specifically, the thickness of the inner wall of the locking groove 411 near the notch 412 is less than the thickness of the inner wall of the locking groove 411 away from the notch 412. In the locked state, the first locking part 41 rotates so that the notch 412 faces towards the support base 1, and the second locking part 42 abuts against the inner wall of the locking groove 411. This design increases the contact area and friction between the first locking part 41 and the second locking part 42, effectively improving the stability of the locked state. The arc plate constrains the second locking part 42, allowing the printing platform 3 to be stably installed on the motion seat 21, avoiding problems such as decreased printing accuracy and model deformation caused by platform loosening during printing, thus improving printing quality and reliability. Furthermore, compared to the structure where the inner wall thickness of each position of the locking groove 411 is uniform, this solution is more labor-saving to operate, facilitates the entry of the second locking part 42 into the locking groove 411, and improves the connection stability in the locked state.

[0095] The structural design of the locking device 4 makes full use of limited space. The layout of the locking groove 411, the notch 412, and the first clearance through hole 212 is compact and reasonable, minimizing the size and space occupied by the locking device 4 while ensuring the locking function. This not only makes the overall structure of the printer more compact, facilitating installation and portability, but also provides more space for the layout of other components of the printer, which is conducive to the miniaturization and integration of the printer.

[0096] In this embodiment, the number of second locking parts 42 is the same as the number of locking wheels 413 of the first locking part 41, and they are correspondingly arranged to ensure the coordinated operation of each component. The second locking part 42 includes a support body 421 and a locking shaft 422. The locking shaft 422 is connected to the printing platform 3 through the support body 421, and at least a portion of the structure of the locking shaft 422 is accommodated within the locking groove 411.

[0097] The support body 421 is firmly fixed to the printing platform 3 by bolts, screws, welding, etc., providing a stable support base for the locking shaft 422 and ensuring that the locking shaft 422 is in a stable and reliable position during the locking process. The support body 421 adopts a spring-loaded design, which can deform to a certain extent during installation, allowing the locking shaft 422 to smoothly enter the locking groove 411, avoiding installation difficulties caused by limited installation space, and improving installation efficiency and success rate.

[0098] Furthermore, when the locking device 4 is in the locked state, the locking shaft 422 can abut against the inner wall of the locking groove 411, thereby improving the reliability of locking between the first locking part 41 and the second locking part 42.

[0099] In one embodiment of this application, the second locking part 42 is rotatably connected to the printing platform 3, and the rotation direction of the second locking part 42 relative to the printing platform 3 is the axial direction of the second locking part 42. Specifically, the locking shaft 422 includes, for example, a rotating shaft block 4221, a locking bearing 4222, and a retaining ring 4223. The modular design of the locking shaft 422, with the rotating shaft block 4221 fixedly connected to the support body 421, ensures the stable position of the locking shaft 422 during the locking process, effectively reducing the problem of inaccurate locking caused by the shaking or displacement of the locking shaft 422, and improving the locking accuracy and stability.

[0100] The locking bearing 4222 is mounted on the rotating shaft block 4221. Its high-precision rolling contact surface reduces frictional resistance and improves the smoothness and accuracy of the locking process. Simultaneously, the load-bearing capacity of the locking bearing 4222 ensures the stability of the locking device 4 under heavy loads, further enhancing locking performance. The locking bearing 4222 abuts against the locking groove 411, and its cylindrical shape facilitates a tight fit with the inner wall of the locking groove 411.

[0101] By installing the snap ring 4223 on the outside of the locking bearing 4222, the locking bearing 4222 can be effectively prevented from disengaging from the rotating shaft block 4221 due to vibration or external force during operation. This not only improves the overall structural strength of the locking shaft 422, but also ensures the continuity and reliability of the locking process.

[0102] The modular design of the locking shaft 422 makes it easy to disassemble and assemble the components. When the locking bearing 4222 wears or is damaged due to prolonged use, the user can easily replace the locking bearing 4222 by simply removing the retaining ring 4223, without the need for complex repairs to the entire locking shaft 422. This design reduces maintenance costs and increases the service life of the locking device 4.

[0103] The combined design of the rotating shaft block 4221, the locking bearing 4222, and the retaining ring 4223 gives the locking shaft body 422 a certain degree of versatility and adaptability. By adjusting the model and specifications of the locking bearing 4222 and selecting a suitable retaining ring 4223 size, the locking shaft body 422 can be adapted to the needs of different equipment and application scenarios. This design improves the flexibility and market competitiveness of the locking device 4.

[0104] It should be noted that the printer in this embodiment is not limited to the structure described above, such as... Figure 1 As shown, it also includes, for example, a printhead 5, a housing 6, and an ink cartridge 7 mounted on the housing 6. The printhead 5 is mounted on the frame 1 and slidably connected to the frame 1. The printhead 5 moves along the second direction of the printer (refer to...). Figure 3 The X-axis shown is perpendicular to the printer's first direction (refer to the X-axis). Figure 3 The Y-axis shown is perpendicular. The ink cartridge 7 is used to hold ink and is connected to the printhead 5. The support base 1 can move along the height direction within the housing 6. By using a slot structure and lifting mechanism, the support base 1 can be raised and lowered, changing the relative position of the support base 1 and the printhead 5, thereby meeting different printing needs.

[0105] The locking device 4 provided in this embodiment switches between locking and releasing states by rotating the first locking part 41, making operation simple and convenient. The locking groove 411 and the second locking part 42 are precisely matched. The locking groove 411 is set as an eccentric circle, and the thickness of the inner wall of the locking groove 411 near the notch 412 is less than the thickness of the inner wall of the locking groove 411 away from the notch 412. During the rotation of the first locking part 41 relative to the second locking part 42, the distance between the outer surface of the second locking part 42 and the inner wall of the locking groove 411 gradually decreases, increasing the contact area and friction, and improving locking stability. Compared with the solution where the inner wall of the locking groove 411 has a uniform thickness, this solution achieves a labor-saving effect and further improves the ease of operation of the locking device 4. Moreover, the locking device 4 has a compact and reasonable structure, effectively reducing volume and space occupation, which is conducive to the miniaturization and integration of printers. In addition, the locking shaft 422 adopts a modular design, which not only facilitates disassembly and assembly but also reduces maintenance costs and extends service life. The combination design of the locking shaft 422 gives it good versatility and adaptability, further improving the flexibility and market competitiveness of the locking device.

[0106] Second Embodiment

[0107] This embodiment provides a printer, such as Figures 2-6 As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar structure as the printer provided in the first embodiment, except that the first locking part 41 in this embodiment includes a synchronous shaft 414, with a locking wheel 413 at each end of the synchronous shaft 414. In this embodiment, there are two locking wheels 413. The synchronous shaft 414 can extend either along a first direction or a second direction of the printer; this embodiment will describe its extension along the first direction of the printer as an example.

[0108] The synchronous shaft 414 is rotatably mounted on the motion seat 21. To ensure the stability of the synchronous shaft 414 during rotation, a first connecting ear 213 is provided on the motion seat 21, through which the synchronous shaft 414 rotatably passes. This installation method allows the synchronous shaft 414 to maintain good stability during rotation, reducing the impact on the performance of the locking device 4 caused by rotational instability. The first connecting ear 213 provides reliable support and positioning for the synchronous shaft 414, enabling it to rotate smoothly in a predetermined position.

[0109] Two locking wheels 413 are mounted on both ends of a synchronous shaft 414 by a fixed sleeve, which allows the two locking wheels 413 to rotate synchronously with the help of the synchronous shaft 414. When the synchronous shaft 414 rotates, the locking wheels 413 at both ends will rotate at the same angular velocity, thus ensuring the consistency of the two locking wheels 413 in their operation.

[0110] When the locking device 4 performs locking or releasing operations, the locking wheels 413 on both sides interact with the second locking part 42 simultaneously. Because the two locking wheels 413 rotate synchronously, the force they apply to the second locking part 42 is more even and stable. This design with locking wheels 413 on both sides, compared to a single-sided locking wheel design, can effectively reduce locking instability caused by uneven force on one side.

[0111] The locking wheels 413 are provided on both sides, which makes the interaction between the first locking part 41 and the second locking part 42 more stable. After the printing platform 3 is installed on the motion seat 21, it can maintain its relative position with the motion seat 21 more stably, reducing the shaking or displacement of the printing platform 3 caused by unstable locking, and improving the reliability and stability of the entire locking device 4.

[0112] With the enhanced stability of the locking device 4, the printing platform 3 maintains a more stable state during printing, thus ensuring the printer's accuracy. A stable printing platform 3 ensures that the distance between the print head and the printing medium remains consistent during printing, reducing printing errors caused by platform movement and improving print quality.

[0113] The synchronous shaft 414 is rotatably mounted on the motion seat 21 and achieves stable rotation through the first connecting ear 213. This structural design is reasonable and compact. It not only improves the working performance of the locking device 4, but also reduces potential failure points caused by structural complexity, thus lowering the printer's maintenance costs. At the same time, this design facilitates the assembly and disassembly of the locking device 4, improving production efficiency.

[0114] In this embodiment, the printer enhances the stability and reliability of the locking device 4 by setting synchronously rotating locking wheels 413 at both ends of the first locking part 41 and optimizing the installation method of the synchronous shaft 414, thereby improving the printing accuracy of the printer and optimizing the structural design of the printer, which has significant beneficial effects.

[0115] Third Embodiment

[0116] This embodiment provides a printer, such as Figures 2-6As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar structure as the printer provided in the second embodiment, except that the first locking part 41 in this embodiment includes a synchronous shaft 414, a first drive part 415, and a first transmission part 416.

[0117] Two synchronous shafts 414 are symmetrically arranged along the first direction of the printer. A first drive unit 415 is connected to a first transmission unit 416, and the first transmission unit 416 is connected to each of the two synchronous shafts 414. Each synchronous shaft 414 has a locking wheel 413 at both ends. The four locking wheels 413 are positioned near the four corners of the moving base 21, achieving multi-point locking and improving the stability of the adapter 31 during installation, ensuring a balanced locking effect. This multi-point locking design makes the printing platform 3 experience more even force during locking, reducing shaking or tilting of the printing platform 3 caused by uneven local force, and improving the installation accuracy and stability of the printing platform 3.

[0118] The first drive unit 415 is disposed on the motion seat 21. The first drive unit 415 and the two synchronous shafts 414 are connected through the first transmission unit 416 to drive the two synchronous shafts 414 to rotate synchronously. The first drive unit 415 drives the first transmission unit 416 to perform circumferential motion, thereby driving the two synchronous shafts 414 to rotate synchronously, simplifying the operation difficulty during locking and effectively improving the locking efficiency.

[0119] First Example

[0120] The first drive unit 415 includes, for example, a pusher 4151 and two synchronous pulleys 4152, and the first transmission unit 416 is, for example, a synchronous belt, which is connected to the pusher 4151 via a first belt tension adjuster 4161.

[0121] The motion seat 21 is equipped with a slide rail 214, and the pusher 4151 is slidably disposed within the slide rail 214. The user generates driving force by pushing the pusher 4151 to slide along the slide rail 214. This design, which uses the pusher 4151 as a power source, greatly simplifies the operation process, reduces the difficulty of operation, and enables the user to easily and quickly achieve the locking and releasing functions.

[0122] The synchronous belt, serving as the first transmission unit 416, is tightly connected to the pusher 4151 via the first belt tension adjuster 4161, ensuring that the driving force generated by the pusher 4151 can be stably and accurately transmitted to the synchronous belt. The synchronous belt is fitted onto two synchronous pulleys 4152, which are fitted onto corresponding synchronous shafts 414. When the pusher 4151 slides, it drives the synchronous belt in a circular motion. The rotation of the synchronous pulleys 4152 is highly synchronized with the movement of the synchronous belt, thereby driving the smooth rotation of the synchronous shafts 414. This synchronization mechanism ensures the stability and reliability of the locking device 4 during locking or releasing.

[0123] The design of the slide rail 214 not only provides stable guidance for the pusher but also makes the entire locking device 4 more compact. Furthermore, the design of key components such as the timing belt and timing pulley 4152 makes them easy to disassemble and replace, reducing maintenance costs and time. Key components such as the pusher 4151, timing belt, and timing pulley 4152 are made of high-strength, wear-resistant materials, capable of withstanding significant forces and friction, thus extending the service life of the locking device 4. The first belt tension adjuster 4161 also ensures that the timing belt always maintains appropriate tension, preventing malfunctions and damage caused by slackness or over-tension.

[0124] Second example

[0125] The first drive unit 415 includes a drive body (not shown in the figure) and a drive wheel (not shown in the figure). The first transmission unit 416 is, for example, a chain. Its implementation principle and setting method are the same as those in the first example above. They all rely on linear motion to realize the rotation of the synchronous shaft 414. Here, it will not be described in detail.

[0126] Alternatively, the first drive unit 415 may include, for example, a rotating rod (not shown) and two rotating wheels (not shown), and the first transmission unit 416 may be a chain. The rotating rod is rotatably mounted on the motion seat 21, and the outer peripheral sidewall of the rotating rod is provided with teeth, so that the rotating rod is engaged with the chain. The chain is engaged on the two rotating wheels, and the two rotating wheels are respectively sleeved on the corresponding synchronous shafts 414.

[0127] The user can generate driving force by rotating the lever, which in turn drives the chain to rotate. The chain meshes with the pulley, driving the two synchronous pulleys 4152 to rotate. The synchronous pulleys 4152 are fixedly connected to the synchronous shaft 414, driving the synchronous shaft 414 to rotate. The locking wheel 413 is fixedly connected to the synchronous shaft 414, driving the locking wheel 413 to rotate, thus locking or releasing the locking device 4. The chain, lever, and pulley are made of high-strength, wear-resistant materials, ensuring the stability and durability of the transmission, thereby extending the service life of the locking device 4.

[0128] The first drive unit 415 drives the two synchronous shafts 414 to rotate synchronously, simplifying the locking operation. Whether using a sliding handle or a rotating rod, users can easily and quickly achieve locking and releasing functions, effectively improving locking efficiency. This design reduces the complexity and time cost of manual operation, enhancing the printer's ease of use.

[0129] The printer in this embodiment enhances the stability of the locking device 4, simplifies operation, optimizes structural design, and ensures transmission stability by setting two synchronous shafts 414 in the first locking part 41, using a first driving part 415 and a first transmission part 416 to achieve synchronous rotation, and employing multiple driving methods. This has significant beneficial effects.

[0130] Fourth embodiment

[0131] This embodiment provides a printer, such as Figures 2-8 As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar structure as the printers provided in the first to third embodiments, except that the printer in this embodiment also includes a first positioning part 211 and a second positioning part 311.

[0132] One of the first positioning part 211 and the second positioning part 311 is disposed on the motion device 2, and the other of the first positioning part 211 and the second positioning part 311 is disposed on the printing platform 3. The motion device 2 and the printing platform 3 are detachably connected through the first positioning part 211 and the second positioning part 311. In this embodiment, the explanation is given by taking the example of the first positioning part 211 being disposed on the motion device 2 and the second positioning part 311 being disposed on the printing platform 3.

[0133] The first positioning part 211 includes two positioning grooves 2111, which are symmetrically arranged along a first direction of the printer. The second positioning part 311 includes two positioning blocks 3111, which are inserted into the positioning grooves 2111 to achieve a coarse positioning connection between the motion seat 21 and the adapter seat 31. The positioning grooves 2111 are located near the end of the motion seat 21. This arrangement improves the stability of the connection between the motion seat 21 and the adapter seat 31, making the positioning blocks 3111 more accurate and stable when inserted into the positioning grooves 2111.

[0134] To further improve positioning and installation performance, the first positioning part 211 also includes a positioning pin 2112, which is disposed within the positioning groove 2111. The second positioning part 311 also includes a positioning hole 3112, which is disposed within the positioning block 3111. The positioning pin 2112 and the positioning hole 3112 are connected by insertion to achieve a precise positioning connection when the motion seat 21 and the adapter seat 31 are connected. This precise positioning connection ensures a more accurate relative position between the motion seat 21 and the adapter seat 31, improving installation efficiency and reducing adjustment time during installation.

[0135] Each positioning slot 2111 can be equipped with a positioning pin 2112. This method enables rapid positioning and installation, allowing the positioning block 3111 to quickly align with the positioning pin 2112 and achieve precise positioning when inserted into the positioning slot 2111. Alternatively, one positioning pin 2112 can be set in one of the positioning slots 2111 to achieve foolproof installation, preventing incorrect orientation or position during installation. Of course, multiple positioning pins 2112 can also be set in each positioning slot 2111, spaced apart, with the spacing designed according to actual needs. For example, to achieve foolproof installation, the spacing can be different, ensuring that the positioning block 3111 can only be inserted in the correct orientation and position; or for convenience, they can be set at equal intervals to facilitate the insertion and positioning of the positioning block 3111.

[0136] The design of the first positioning part 211 and the second positioning part 311 realizes both coarse and fine positioning connections between the motion seat 21 and the adapter seat 31. Coarse positioning is achieved by inserting the positioning block 3111 into the positioning groove 2111, ensuring the initial accuracy of the connection; fine positioning is achieved by inserting the positioning pin 2112 into the positioning hole 3112, further improving the accuracy and stability of the positioning. This dual positioning mechanism ensures a more reliable connection between the motion device 2 and the printing platform 3, reducing printing errors or equipment malfunctions caused by inaccurate positioning.

[0137] The positioning pin 2112 and positioning hole 3112 make the installation process more convenient and efficient. The quick-positioning and foolproof installation design reduces adjustment time and error rate during installation, improving installation efficiency. At the same time, the positioning groove 2111 near the end of the motion seat 21 also improves the stability of the connection, further optimizing the installation effect.

[0138] The printer provided in this embodiment, by adding a first positioning part 211 and a second positioning part 311, realizes a detachable connection between the motion device 2 and the printing platform 3, which improves the printer's flexibility of use, positioning accuracy and installation efficiency, meets differentiated needs and has significant beneficial effects.

[0139] Fifth embodiment

[0140] This embodiment provides a printer, such as Figures 2-12 As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar printer structure as any of the first to fourth embodiments, except that the printing platform 3 in this embodiment includes, for example, a first flat plate 33, an adapter 31, and a first drive mechanism 32. The adapter 31 is detachably connected to the motion base 21, and the first flat plate 33 is movably mounted on the adapter 31. The adapter 31 serves as the fixed foundation for the entire printing platform 3, securely mounted in the appropriate position of the printer, providing a stable support platform for other components.

[0141] The first plate 33 is a movable component capable of sliding or translating relative to the adapter 31. The first drive mechanism 32 is connected to both the first plate 33 and the adapter 31, and applies a driving force to cause the first plate 33 to reciprocate along a first direction of the printer. The first drive mechanism 32 can be any device capable of providing linear driving force, such as an electric motor, linear actuator, pneumatic or hydraulic cylinder; the specific choice depends on factors such as printer performance requirements, cost budget, and space constraints.

[0142] In this embodiment, the first drive mechanism 32 includes a second drive part 321 and two first guide parts 322. The two first guide parts 322 are symmetrically arranged along the first direction of the printer, and the first guide parts 322 provide guidance and support. The first guide parts 322 are, for example, optical axes, and are fixedly connected to the first plate 33 by bolts or welding to improve the reliability of the connection and prevent loosening or displacement during movement.

[0143] Each first guide portion 322 penetrates the adapter 31, providing stable guidance for the first flat plate 33 and restricting the movement direction of the adapter 31, keeping it moving along the first direction of the printer. Exemplarily, the adapter 31 has two second connecting lugs 312 symmetrically arranged along the first direction of the printer, providing mounting points for the first guide portions 322. Each second connecting lug 312 has a second through hole 3121, within which a second bearing 3122 is embedded. The second connecting lug 312 is fitted onto the corresponding first guide portion 322 via the second bearing 3122, achieving smooth and low-friction movement.

[0144] The second drive unit 321 is disposed on the adapter 31 and connected to the first platen 33, ensuring that the second drive unit 321 can directly drive the first platen 33 to move. By applying driving force, the second drive unit 321 drives the first platen 33 to reciprocate relative to the adapter 31 along the first direction of the printer, which not only provides stable power output, but also ensures the accuracy and controllability of the movement.

[0145] In this embodiment, the second drive unit 321 includes a first drive motor 3211 and a second transmission unit 3212. The second transmission unit 3212 is connected to the first plate 33 and the first drive motor 3211, respectively. The first drive motor 3211 is disposed on the adapter 31. The first drive motor 3211 provides a power source for the second transmission unit 3212. The first drive motor 3211 generates torque through rotation, and this torque is transmitted to the first plate 33 through the second transmission unit 3212, thereby driving it to reciprocate along the first direction of the printer.

[0146] For example, the second conveyor 3212 includes a first conveyor belt 32121, a drive main wheel 32122 and two drive slave wheels 32123, which together constitute a transmission system for transmitting the power of the first drive motor 3211 to the first flat plate 33.

[0147] A second belt tension adjuster 32124 is connected to a first plate 33 at each end of the first conveyor belt 32121. When the first conveyor belt 32121 moves, the first plate 33 also moves accordingly. The first conveyor belt 32121 is connected to the drive main wheel 32122, which is connected to the output shaft of the first drive motor 3211. When the output shaft of the first drive motor 3211 rotates, the drive main wheel 32122 also rotates accordingly. The housing of the first drive motor 3211 is fixedly connected to the adapter 31 to improve the stability of the first drive motor 3211.

[0148] Two driven wheels 32123 are symmetrically arranged on both sides of the main drive wheel 32122 along the second direction of the printer. The driven wheels 32123 press against the first conveyor belt 32121 to ensure the smooth operation of the first conveyor belt 32121.

[0149] When the first drive motor 3211 drives the drive main wheel 32122 to rotate, the first conveyor belt 32121 will start to move due to the friction between the first conveyor belt 32121, the drive main wheel 32122, and the two drive driven wheels 32123. The drive main wheel 32122 and the drive driven wheels 32123 rotate synchronously, and the first flat plates 33 connected to both ends of the first conveyor belt 32121 reciprocate. By controlling the rotation direction and speed of the first drive motor 3211, the movement direction and speed of the first flat plate 33 can be precisely controlled.

[0150] In this embodiment, the printing platform 3 is driven by the first drive mechanism 32 to reciprocate along the first direction of the printer, providing a stable and precise motion platform for the printer head or other moving components. This design not only improves the printing accuracy and efficiency of the printer but also enhances its overall performance and reliability.

[0151] In this embodiment, the motion device 2 further includes a second drive mechanism 23, so that the motion seat 21 can be driven by the second drive mechanism 23.

[0152] The support base 1 is provided with a receiving space 11 and a third clearance through hole 12 communicating with the receiving space 11. There are two third clearance through holes 12, which are symmetrically arranged along the first direction of the printer.

[0153] The second drive mechanism 23 is located within the accommodating space 11, which not only helps protect the second drive mechanism 23 from external interference, but also makes effective use of space, making the overall structure more compact.

[0154] A portion of the structure of the motion base 21 passes through the third clearance through hole 12 into the receiving space 11 and is connected to the second drive mechanism 23. Exemplarily, the motion base 21 is symmetrically provided with two first connecting lugs 216 along the first direction of the printer. The first connecting lugs 216 pass through the corresponding third clearance through hole 12 and are connected to the second drive mechanism 23, ensuring that the motion base 21 can be connected to the second drive mechanism 23 in a balanced and stable manner. The second drive mechanism 23 can drive the motion base 21 to reciprocate on the support base 2.

[0155] In this embodiment, the second drive mechanism 23 includes a third drive part 231 and two second guide parts 232. The second guide parts 232 are, for example, optical axes, which are fixedly connected to the support base 1 by bolts or welding. Each second guide part 232 corresponds to a third clearance through hole 12, so that part of the structure of the motion seat 21, namely the first connecting lug 216, can pass through the corresponding third clearance through hole 12 and cooperate with the second guide part 232.

[0156] For example, the first connecting lug 216 may be provided with a first through hole 2161, in which a first bearing 2162 is embedded. The first connecting lug 216 is sleeved on the corresponding second guide portion 232 through the first bearing 2162. The first bearing 2162 can greatly reduce the frictional resistance when the first connecting lug 216 slides on the second guide portion 232, ensuring the smoothness and fluidity of the movement. Through the first bearing 2162, the first connecting lug 216 can be tightly and flexibly sleeved on the corresponding second guide portion 232, forming a stable guiding and supporting structure.

[0157] The third drive unit 231 is connected to the first connecting lug 216 of the motion seat 21. The third drive unit 231 drives the motion seat 21 to reciprocate on the second guide portion 232 via the first connecting lug 216. The third drive unit 231, as the source of driving force, is connected to the first connecting lug 216 of the motion seat 21. This connection can be a direct mechanical connection or an indirect connection via a transmission mechanism such as gears or belts. Regardless of the method used, the third drive unit 231 can effectively drive the motion seat 21 to reciprocate on the second guide portion 232 via the first connecting lug 216. The axis of the second guide portion 232 is aligned with the first direction of the printer. When the third drive unit 231 drives the motion seat 21, the motion seat 21 will reciprocate precisely along the first direction of the printer, thus meeting the requirements of the printer for motion trajectory and accuracy when performing printing tasks.

[0158] For example, the third drive unit 231 includes a second drive motor 2311, a third transmission unit 2312, a drive shaft 2313, and a connecting plate 2314. The housing of the second drive motor 2311 is fixedly connected to the support base 1, and the motor shaft of the second drive motor 2311 serves as the power output end for driving the operation of subsequent components. The motor shaft of the second drive motor 2311 is connected to the third transmission unit 2312, and the third transmission unit 2312 is connected to one end of the drive shaft 2313. The third transmission unit 2312 includes, for example, a first transmission wheel 23121, a second transmission wheel 23122, and a second conveyor belt 23123. The first transmission wheel 23121 is fixedly sleeved on the motor shaft of the second drive motor 2311 and rotates with it. The second transmission wheel 23122 is fixedly sleeved on one end of the drive shaft 2313, maintaining a certain distance from the first transmission wheel 23121. The second conveyor belt 23123 is tightly fitted onto the first transmission wheel 23121 and the second transmission wheel 23122. When the first transmission wheel 23121 rotates, the second transmission wheel 23122 and the drive shaft 2313 are driven to rotate synchronously through the transmission action of the second conveyor belt 23123.

[0159] The drive shaft 2313 is, for example, a lead screw. The other end of the drive shaft 2313 is rotatably connected to the support base 1, ensuring that the drive shaft 2313 can rotate smoothly and flexibly on the support base 1. The connecting plate 2314 can be screwed onto the drive shaft 2313. The two ends of the connecting plate 2314 are respectively fixedly connected to the two first connecting lugs 216 of the motion seat 21, thereby forming an integral motion unit.

[0160] When the second drive motor 2311 starts, its motor shaft begins to rotate, thereby driving the first transmission wheel 23121 to rotate. Through the transmission action of the second conveyor belt 23123, the second transmission wheel 23122 and the drive shaft 2313 rotate synchronously. Since the drive shaft 2313 adopts a lead screw form and the connecting plate 2314 can be screwed to it, when the drive shaft 2313 rotates, the connecting plate 2314 will slide along the axial direction of the drive shaft 2313. This sliding motion is further transmitted to the motion seat 21 through the connection relationship between the connecting plate 2314 and the motion seat 21, causing it to perform linear motion under the guidance of the second guide part 232.

[0161] In this embodiment, the third drive unit 231 further includes a second elastic element 2315, which is sleeved on the drive shaft 2313. The two ends of the second elastic element 2315 abut against the connecting plate 2314 and the support base 1, respectively. The second elastic element 2315 is, for example, a spring, and has good elasticity and restoring force.

[0162] The second elastic element 2315 is mainly designed to address the potential clearance issues that may arise during the movement of the drive shaft 2313. Because there are certain tolerances in the fit between mechanical components, these tolerances may increase the clearance between components after prolonged operation, thereby affecting the stability and accuracy of the movement.

[0163] The second elastic element 2315 acts as a compensating element, filling these gaps in real time to ensure that the connecting plate 2314 and the drive shaft 2313 always maintain a tight contact. When the drive shaft 2313 rotates, the connecting plate 2314 slides smoothly in the helical groove of the lead screw, while the second elastic element 2315 provides the necessary elasticity and restoring force to cope with possible gap changes.

[0164] In addition, the second elastic element 2315 can also absorb and buffer the impact and vibration during the motion process to a certain extent, further improving the stability and durability of the entire transmission system.

[0165] In this embodiment, the motion device 2 also includes a zeroing switch 25, which is disposed on the second guide portion 232 to facilitate the motion seat 21 to return to its initial position, thereby improving printing accuracy.

[0166] The second drive mechanism 23 in this embodiment realizes stable and precise linear movement of the motion seat 21 on the support base 1, which not only improves the motion accuracy and stability of the printer, but also provides convenience for subsequent maintenance and upgrades.

[0167] In this embodiment, the first drive mechanism 32 and the second drive mechanism 23 can be powered by external power supply devices. Alternatively, they can be powered synchronously. For example, the printer also includes a first electrical connection module 22 and a second electrical connection module 34. The first electrical connection module 22 is disposed on the motion seat 21 and electrically connected to the second drive mechanism 23. The second electrical connection module 34 is disposed on the adapter seat 31 and electrically connected to the first drive mechanism 32. The motion device 2 and the printing platform 3 are electrically connected through the first electrical connection module 22 and the second electrical connection module 34.

[0168] The motion seat 21 is provided with a first groove 215, which not only helps to reduce the weight of the motion seat 21 and improve its mechanical performance, but also provides a suitable installation position for the first electrical connection module 22.

[0169] In order to expose part of the structure of the first electrical connection module 22 so as to make contact with the second electrical connection module 34, a second clearance through hole 2151 is provided on the side wall of the first groove 215. The position and size of the second clearance through hole 2151 are based on the actual situation to ensure that the part of the first electrical connection module 22 that needs to contact the printing platform 3 can be accurately exposed.

[0170] In practical applications, when the motion device 2 is assembled with the printing platform 3, the corresponding first electrical connection module 22 on the printing platform 3 is exposed so as to make contact with the second electrical connection module 34 on the printing platform 3 and establish a stable electrical connection, thereby realizing the transmission of signals or electricity.

[0171] For example, the first electrical connection module 22 includes a first electrical connector 221 and a cycloidal wire 222, which is electrically connected to the first electrical connector 221. The cycloidal wire 222 serves as a transmission medium for electrical signals. One end of the cycloidal wire 222 is fixedly connected to the first electrical connector 221. The cycloidal wire 222 has sufficient flexibility and conductivity to ensure stable and efficient transmission of electrical signals. The other end of the cycloidal wire 222 extends out of the motion seat 21 and into the support base 1 to form a connection with other parts of the printer or external devices. The first electrical connector 221 may be, for example, a quick-connect male connector.

[0172] The second electrical connection module 34 is disposed on the adapter 31, so that when the adapter 31 is assembled to the motion seat 21, the second electrical connection module 34 can form an electrical connection with the first electrical connection module 22.

[0173] For example, in order to accurately align and achieve electrical connection, the adapter 31 is provided with a protrusion 313. The protrusion 313 protrudes from the surface of the adapter 31, which not only enhances the guidance during assembly, but also provides the necessary space arrangement for electrical connection. The sidewall of the protrusion 313 is provided with a fourth clearance through hole 3131 to expose part of the structure of the second electrical connection module 34, so as to facilitate docking with the first electrical connection module 22, without affecting the layout of other assembly or functional components.

[0174] When the adapter 31 is assembled onto the motion seat 21, the protrusion 313 can be inserted into the first groove 215. This plug-in design not only achieves physical positioning connection but also ensures precise alignment between the second electrical connection module 34 and the first electrical connection module 22. The second electrical connection module 34 is, for example, a quick-connect motherboard. This type of electrical connector is known for its fast and reliable connection characteristics, making it ideal for applications requiring frequent assembly or disassembly.

[0175] When the protrusion 313 is correctly inserted into the first groove 215, a stable contact electrical connection will be formed between the quick-connect female board (i.e., the second electrical connection module 34) and the first electrical connection module 22 (the matching quick-connect male board), thereby ensuring the smooth transmission of electrical signals.

[0176] In this embodiment, the first electrical connection module 22 can be fixedly mounted on the motion seat 21 to improve its stability. Alternatively, the first electrical connection module 22 can be movably mounted on the motion seat 21 to improve its flexibility. When not in use, the first electrical connection module 22 can be retracted a certain distance from the second clearance through hole 2151 to be stored and protected.

[0177] First Example

[0178] The printer also includes an elastic drive unit (not shown in the figure) disposed on the motion base 21 to realize the retractable state of the first electrical connection module 22. That is, the elastic drive unit is connected to the first electrical connection module 22, and the elastic drive unit is configured to drive the first electrical connection module 22 to move, so that the first electrical connection module 22 and the second electrical connection module 34 are always in contact electrical connection. The elastic drive unit includes, for example, a spring and a locking member. The spring is disposed in the accommodating space 11 and is connected to the first electrical connection module 22. In the natural state, the spring releases its elastic force, pushing the first electrical connection module 22 to the second electrical connection module 34 to ensure that the two are always connected. When the printing platform 3 is disassembled, in order to avoid damage to the first electrical connection module 22, the first electrical connection module 22 can be pushed by external force to retract it into the second clearance through hole 2151, and locked by the locking member. The locking member is, for example, a pin, etc., and the locking member can be disposed on the first electrical connection module 22, and screwed to abut against the inner wall of the accommodating space 11.

[0179] Second example

[0180] The printer also includes an auxiliary drive unit 24, which is connected to the locking device 4. When the first locking part 41 rotates, it drives the auxiliary drive unit 24 to move, which in turn drives the first electrical connection module 22 to move, thus forming a contact electrical connection between the first electrical connection module 22 and the second electrical connection module 34. The locking device 4 is used to achieve this linkage.

[0181] The auxiliary drive unit 24 includes, for example, a first connecting seat 241, a first support seat 242, a first elastic element 243, a first drive block 244, and a second drive block 245. These parts work together to achieve a stable contact-type electrical connection and disconnection function between the first electrical connection module 22 and the printing platform 3.

[0182] The first connecting seat 241 is fixedly connected to the moving seat 21 by means of bolts or welding, thereby ensuring the stability and reliability of the first connecting seat 241.

[0183] The first electrical connector 221 is connected to the first support base 242, which is movably disposed on the first connecting base 241, allowing the first electrical connector 221 to move within a certain range to adapt to changes in its relative position with the printing platform 3. For example, the first support base 242 has protruding rods 2421 at both ends along the first direction of the printer, and the first connecting base 241 has second grooves 2411 corresponding to the protruding rods 2421. The protruding rods 2421 are placed in the second grooves 2411, and the size of the second grooves 2411 is slightly larger than the size of the protruding rods 2421, so that the protruding rods 2421 can move within a certain range in the second grooves 2411, thereby driving the first support base 242 to move.

[0184] The first support base 242 is connected to the locking device 4 via the auxiliary drive unit 24. When the first locking unit 41 rotates, it drives the auxiliary drive unit 24 to move, thereby driving the first support base 242 along the second direction of the printer (see reference). Figure 3 The X-axis (as shown) moves relative to the first connecting seat 241, that is, the first support seat 242 moves towards the adapter seat 31, so that the first electrical connection module 22 and the printing platform 3 form a contact electrical connection. This has the advantages of stability, reliability, and ease of maintenance, and can meet the electrical connection requirements of high-precision equipment such as printers. The second direction, the first direction, and the vertical direction of the printer are all perpendicular to each other, which helps to optimize the printer's structural layout and improve the compactness and stability of the equipment.

[0185] The first drive block 244 is fixedly mounted on the first support base 242, and the second drive block 245 is fixedly mounted on the synchronous shaft 414 of the locking device 4. When the first locking part 41 of the locking device 4 rotates, it will drive the second drive block 245 to perform corresponding movements.

[0186] The first elastic element 243 is, for example, a torsion spring. One end of the first elastic element 243 abuts against the first support 242, and the other end of the first elastic element 243 abuts against the first connecting seat 241. The design of the torsion spring allows it to deform when subjected to external force and automatically return to its original position after the external force is removed.

[0187] When the first locking part 41 rotates, that is, when the locking device 4 is in the locked state, the synchronous shaft 414 drives the second driving block 245 to move. A protrusion 2451 is provided on one side of the second driving block 245, which abuts against the first driving block 244 until it presses against the first driving block 244. This, in turn, pushes the first support seat 242 to move towards the first connecting seat 241 along the second direction of the printer. The first electrical connector 221 of the first electrical connection module 22 gradually approaches the printing platform 3 and eventually forms a contact electrical connection. During this process, the first elastic element 243 deforms, storing a certain amount of elastic potential energy. The first locking part 41 can rotate clockwise or counterclockwise, depending on the actual situation.

[0188] When it is necessary to disconnect the electrical connection between the first electrical connection module 22 and the printing platform 3, the first locking part 41 rotates in the opposite direction, that is, the synchronous shaft 414 rotates, driving the second drive block 245 to move. The protruding part of the second drive block 245 will retract from the first drive block 244. At this time, the first elastic element 243 will release the previously stored elastic potential energy to achieve a reset, pushing the first support base 242 to move away from the first connection base 241 along the second direction of the printer, thereby causing the first electrical connection body 221 of the first electrical connection module 22 to gradually separate from the printing platform 3.

[0189] The selection and design of the first elastic element 243 are crucial for achieving stable and reliable electrical connection and disconnection. The stiffness and preload of the torsion spring need to be precisely calculated and selected according to the actual application scenario and requirements to ensure that sufficient driving force can be generated when the first locking part 41 rotates and that it can be smoothly reset when disconnected.

[0190] In this embodiment, the auxiliary drive unit 24, through its reasonable structural design and working principle, achieves a stable contact-type electrical connection and disconnection function between the first electrical connection module 22 and the printing platform 3. This design not only has the advantages of simple structure and easy maintenance, but also can adapt to changes in different application scenarios and needs.

[0191] The printer provided in this embodiment uses a first drive mechanism 32 to drive a first flat plate 33 to reciprocate along a first direction of the printer, providing a stable and precise motion platform for the printer head and other components, improving printing accuracy and efficiency, and enhancing overall performance and reliability. Furthermore, the motion base 21 and the first flat plate 33 can be stacked to accommodate larger printing areas. The second drive mechanism 23 enables stable and precise linear motion of the motion base 21 on the support base 1, improving motion accuracy and stability, and facilitating subsequent maintenance and upgrades.

[0192] The motion device 2 and the printing platform 3 are electrically connected through the first electrical connection module 22 and the second electrical connection module 34, and can be powered synchronously. The design of the elastic drive unit or auxiliary drive unit 24 ensures that the electrical connection is stable and reliable. The auxiliary drive unit 24 has a simple structure, is easy to maintain, and can adapt to different application scenarios and changes in requirements.

[0193] The addition of a detachable printing platform 3 allows the printer to select the appropriate printing platform 3 to work with the motion device 2 as needed, and connect them through the locking device 4, thereby improving the printer's range of use and flexibility to meet different usage requirements.

[0194] Sixth Embodiment

[0195] This embodiment provides a printer, such as Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar structure as the printer provided in any of the first to fifth embodiments, except that the printing platform 3 in this embodiment includes a second plate 36, which is detachably connected to the motion base 21, and the second plate 36 moves synchronously with the motion base 21.

[0196] Specifically, the detachable connection between the second plate 36 and the motion seat 21 can be achieved by the locking device 4. The locking device 4 has a first locking part 41 and a second locking part 42. Through the cooperation of the first locking part 41 and the second locking part 42, the second plate 36 can be firmly locked onto the motion seat 21, thereby improving the reliability of the connection between the second plate 36 and the motion seat 21.

[0197] In another embodiment, to simplify the connection method, the second locking part 42 may not be provided on the second plate 36. For example, the second plate 36 is provided with a limiting protrusion 361. When the second plate 36 is installed on the motion seat 21, the limiting protrusion 361 will be accommodated in the locking groove 411 through the notch 412, thereby realizing the connection between the second plate 36 and the motion seat 21.

[0198] Furthermore, the number of limiting protrusions 361 is the same as the number of locking wheels 413 of the first locking part 41. When multiple limiting protrusions 361 are provided, a multi-point locking design is formed. This multi-point locking design not only significantly enhances the stability of the structure, but also effectively prevents overall failure due to single-point failure, thereby ensuring the stability and durability of the printer during high-speed, high-precision operations.

[0199] To further improve the positioning connection between the second plate 36 and the motion seat 21, the second plate 36 is connected by a positioning block 3111 and a positioning groove 2111. The positioning block 3111 and the positioning groove 2111 can be in an interference fit, which can improve the reliability of the connection. The specific details of this positioning connection have been described in detail in the fourth embodiment and will not be repeated here.

[0200] In this embodiment, the cross-sectional dimension of the second plate 36 is smaller than that of the first plate 33. This difference in cross-sectional dimensions reflects the consideration of different application scenarios in this disclosure. Due to its smaller cross-sectional dimension, the second plate 36 is defined as a small-format panel, suitable for situations with limited space or low requirements for print area. The first plate 33, as a large-format panel, is suitable for scenarios requiring a larger print area.

[0201] Users can flexibly choose to install the second platen 36 or the first platen 33 according to their actual needs, or even switch between the two. For example, when the printer only needs to meet basic printing requirements and the printing area does not exceed the printer body area, the user can choose to install the second platen 36. In this case, the movement stroke of the motion seat 21 is restricted inside the printer body, and the printer can perform box sealing printing, thus maintaining the printer's compactness and portability.

[0202] When faced with a wider range of printing needs, users can remove the second platen 36 and instead install the adapter 31 onto the motion base 21, and install the first platen 33 onto the adapter 31. This configuration can significantly expand the printer's printing area, enabling the printer to handle large-format printing tasks, such as printing advertising posters, murals, etc.

[0203] The printer in this embodiment, through the flexible assembly mechanism of printing platform 3, greatly enhances the printer's functional versatility and application flexibility. Users can freely choose to install flatbeds of different sizes according to different printing needs, thereby adapting to different usage scenarios. Whether it's a small-scale printing task or a large-scale printing demand, this printer can easily handle it, providing users with a more convenient and efficient printing solution.

[0204] In related technologies, some systems in UV printers across different application scenarios, such as control systems and drive systems, may share similarities. However, due to differences in overall design, these systems often cannot be directly shared or interchanged. This not only reduces printer utilization but also increases user operating costs.

[0205] The printer disclosed herein allows users to adapt the printing platform 3 to different materials, sizes, or printing requirements when faced with objects, eliminating the need for multiple UV printers. Since some parts of the system can be shared, printer utilization is improved. Users can flexibly switch between different printing modes according to actual needs, such as the second flatbed 36 suitable for small printing areas, and the first flatbed 33 suitable for large printing areas. It can also be used with any other printing fixture equipped with a first locking part 41 or a second locking part 42, adapting to different printing scenarios. Furthermore, the motion device 2 and the printing platform 3 are detachably connected, facilitating the replacement of different printing platforms without sacrificing printing accuracy. This significantly improves the printer's flexibility and versatility while ensuring print quality. Users can quickly adjust and optimize printing configurations according to different application needs, effectively reducing hardware costs and maintenance difficulty.

[0206] Seventh Embodiment

[0207] This embodiment provides a printer, such as Figure 4 , Figure 15 As shown, the printer includes a support base 1, a motion device 2, a printing platform 3, and a locking device 4. It has the same or similar structure as the printer provided in the fifth embodiment, except that the printing platform 3 in this embodiment also includes a self-locking mechanism 35.

[0208] When the adapter 31 and the motion base 21 are in the installed state, the self-locking mechanism 35 is in the released state, and the first plate 33 can reciprocate relative to the adapter 31 along the first direction of the printer.

[0209] When the adapter 31 and the motion seat 21 are detached, the self-locking mechanism 35 is locked and is configured to restrict the movement of the first platen 33 along the first direction of the printer.

[0210] The first platen 33 is limitedly connected to the adapter 31 via a self-locking mechanism 35. The self-locking mechanism 35 can be used to lock the first platen 33 to restrict its movement. When the printer is not in use and the printing platform 3 is removed, the first platen 33 may slide along the first guide portion 322, which could easily trap the user's hand, posing a safety hazard. Therefore, the first platen 33 can be pushed until it falls into the self-locking mechanism 35, thereby locking the first platen 33 and the adapter 31.

[0211] In this embodiment, the self-locking mechanism 35 includes a third elastic element 351, a first limiting part 352, a second limiting part 353, and a button 354. The first limiting part 352 is disposed on the first plate 33, and the second limiting part 353 is rotatably disposed on the adapter 31.

[0212] The second limiting part 353 has a locking end 3533 and a free end 3534. The third elastic member 351 is sandwiched between the locking end 3533 and the adapter 31. The free end 3534 is connected to the button 354, which can movably pass through the adapter 31.

[0213] When the adapter 31 and the motion seat 21 are installed, the motion seat 21 presses the free end 3534 through the button 354, thereby driving the second limiting part 353 to rotate, the third elastic member 351 deforms, and the second limiting part 353 disengages from the first limiting part 352.

[0214] When the adapter 31 and the motion seat 21 are detached, the third elastic element 351 is reset to press the locking end 3533, thereby driving the second limiting part 353 to rotate, and the second limiting part 353 and the first limiting part 352 are connected in a limiting manner.

[0215] For example, the second limiting part 353 includes a locking bracket 3531 and a locking connecting rod 3532. The locking bracket 3531 is connected to the adapter 31 and is used to support and fix the locking connecting rod 3532 to prevent the locking connecting rod 3532 from disengaging from the adapter 31. The locking connecting rod 3532 is rotatably connected to the locking bracket 3531, so that the locking connecting rod 3532 can rotate relative to the locking bracket 3531.

[0216] The locking connecting rod 3532 has a V-shaped structure and includes a locking end 3533 and a free end 3534. A third elastic element 351 is sandwiched between the locking end 3533 and the adapter 31 to receive the restoring force of the third elastic element 351. The free end 3534 is used for external force application to achieve rotation of the locking connecting rod 3532. For ease of operation, a button 354 is also provided on the free end 3534, allowing the user to operate the locking connecting rod 3532 by pressing the button 354.

[0217] The third elastic element 351, such as a spring, provides a restoring force to ensure that the locking connecting rod 3532 automatically returns to the locked position after unlocking. One end of the spring is connected to the locking end 3533 of the locking connecting rod 3532, and the other end is fixed to the adapter 31.

[0218] The first limiting part 352 is disposed on the first plate 33 and is used to cooperate with the second limiting part 353 to realize the locking function. The second limiting part 353 and the first limiting part 352 are connected by a pin hole. For example, the first limiting part 352 is a limiting pin. The locking connecting rod 3532 is provided with a limiting hole 3535 on one side of the locking end 3533.

[0219] When the adapter 31 and the motion seat 21 are installed, the motion seat 21 and the adapter 31 fit together seamlessly. The adapter 31 is provided with a third through hole 314, through which the button 354 can pass, allowing the user to press the button 354 directly from the outside. That is, the motion seat 21 will compress the button 354 at the free end 3534. Since the locking connecting rod 3532 is similar to a seesaw principle, when the free end 3534 is under pressure, the locking connecting rod 3532 will rotate relative to the locking bracket 3531. At this time, the third elastic element 351 deforms and is compressed, and at the same time, the limiting hole 3535 disengages from the limiting pin, thereby unlocking.

[0220] When the adapter 31 and the motion seat 21 are detached, the first plate 33 may slide along the first guide portion 322, potentially trapping the user's hand and posing a safety hazard. Therefore, the first plate 33 can be pushed until it falls into the self-locking mechanism 35, locking the first plate 33 and the adapter 31 and improving the stability of the first plate 33. At this time, because the adapter 31 disengages from the motion seat 21, the pressure on the button 354 is released, the third elastic element 351 resets, and presses the locking end 3533. Due to the seesaw principle of the locking connecting rod 3532, the locking connecting rod 3532 will reverse back to its initial position. During the reversal, the limiting hole 3535 and the limiting pin reconnect, achieving locking.

[0221] The self-locking mechanism 35 in this embodiment has advantages such as simple structure, convenient operation, and reliable locking. Unlocking and locking functions can be easily achieved by pressing button 354, greatly improving ease of use and efficiency. Simultaneously, the use of a spring as the third elastic element 351 ensures that the locking connecting rod 3532 automatically returns to the locked position after unlocking, improving the stability and reliability of the mechanism.
