Description

Technical Field

[0001] This invention relates to the field of printer technology, and in particular to a fixture-type printing platform and a desktop printer. Background Technology

[0002] Desktop printers, as an important branch of miniaturized, high-precision printing equipment, have developed rapidly in recent years due to the rapid growth in demand for personalized customization and small-batch production. Their technological evolution has progressed from initially supporting only flat surface printing to gradually expanding to printing on curved, cylindrical, and other irregularly shaped surfaces, meeting the decorative and labeling needs of everyday items such as cups and pen holders. To achieve stable printing on non-planar objects, the industry has widely introduced roller fixture structures, which convert the linear motion of the printing platform into the rotational motion of the object being printed through mechanical transmission, thereby achieving continuous and uniform pattern coverage.

[0003] Currently, mainstream desktop printers typically use a roller fixture combined with friction drive when printing cylindrical products. Specifically, as the printing platform moves, the friction between its surface and the rollers drives the rollers to rotate around their own axis; the rollers, in turn, cause the cylindrical product to rotate synchronously through contact friction with the product's outer surface, thus "wrapping" the pattern printed by the printhead along a straight path onto the product's surface. This solution is simple in structure, low in cost, and allows for quick replacement of fixtures of different sizes, hence its widespread adoption.

[0004] However, current printing platforms and roller fixtures are prone to printing misalignment during the printing process. Summary of the Invention

[0005] The main objective of this invention is to propose a fixture-type printing platform and desktop printer, which aims to solve the problem of printing misalignment that easily occurs during the printing process in current printing platforms and roller fixtures.

[0006] To achieve the above objectives, this invention proposes a fixture-type printing platform for use in desktop printers. The fixture-type printing platform includes a fixture base and a first fixture. The fixture base includes a mounting plate, a drive component, and an actuating gear. The drive component is mounted on the mounting plate and is connected to the actuating gear via a transmission connection. The first fixture includes a housing, a gear set, and a rotating assembly. The gear set and the rotating assembly are rotatably mounted on the housing. The gear set is connected to the rotating assembly via a transmission connection, and the outer periphery of the rotating assembly is used to abut against the product. The housing is detachably mounted on the mounting plate so that the gear set meshes with the actuating gear.

[0007] In one embodiment, the rotating assembly includes at least two drive shafts and a plurality of jig rollers. The drive shafts are rotatably mounted on the housing. The at least two drive shafts are spaced apart from each other. The drive shafts are connected to a gear set for transmission. A plurality of jig rollers are spaced apart along the outer periphery of each drive shaft. The jig rollers are provided with elastic sealing rings on their outer periphery for contacting the product.

[0008] In one embodiment, the gear set includes a main drive gear and at least two auxiliary drive gears. The main drive gear is rotatably mounted on the housing, and the at least two auxiliary drive gears are fixedly connected to at least two drive shafts. The auxiliary drive gears mesh with the main drive gear. The bottom teeth of the main drive gear protrude from the lower surface of the housing, and the top teeth of the actuating gear are lower than or flush with the upper surface of the mounting plate.

[0009] In one embodiment, the top of the mounting plate is provided with a positioning recess, and the bottom of the outer shell is provided with a positioning protrusion, the positioning protrusion and the positioning recess being positioned and engaged; or, the mounting plate is provided with positioning notches around its perimeter, and the bottom of the outer shell is provided with positioning protrusions around its perimeter, the positioning protrusions and the positioning notches being positioned and engaged.

[0010] In one embodiment, the top of the mounting plate is provided with a magnetic element, and the bottom of the housing is provided with a magnetic element or ferromagnetic metal, and the magnetic element of the mounting plate and the magnetic element or ferromagnetic metal of the housing are magnetically attracted to each other.

[0011] In one embodiment, the fixture-type printing platform further includes a second fixture, which includes at least a phone case receiving shell. The phone case receiving shell is detachably mounted on the mounting plate, and a receiving groove is provided on the top of the phone case receiving shell for receiving a phone case.

[0012] In one embodiment, the receiving groove is provided with a boss and at least two movable clamping members. At least two elastic members are provided on at least two side surfaces of the boss. The clamping members are elastically connected to the boss through the elastic members. The elastic members are used to apply an elastic force to the clamping members in the direction of the edge of the receiving groove.

[0013] In one embodiment, the second fixture further includes a first base plate and a first height compensation member. The first base plate is detachably mounted on the mounting plate, the first height compensation member is mounted on the first base plate, and the phone case receiving shell is mounted on the first height compensation member. The mounting plate has a first opening, and the first base plate has a second opening. The fixture-type printing platform further includes a positioning member that passes through the second opening and the first opening in sequence to position the mounting plate and the first base plate. The first base plate has a magnetic member or ferromagnetic metal, and the magnetic member of the mounting plate magnetically attracts the magnetic member or ferromagnetic metal of the first base plate.

[0014] In one embodiment, the jig-type printing platform further includes a third jig, which includes a second base plate, a second height compensation member, and a placement platform. The second base plate is detachably mounted on a mounting plate, the second height compensation member is mounted on the second base plate, and the placement platform is mounted on the second height compensation member. The mounting plate has a first opening, and the second base plate has a third opening. The jig-type printing platform also includes a positioning member that passes through the third opening and the first opening in sequence to position the mounting plate and the second base plate. The second base plate has a magnetic member or ferromagnetic metal, and the magnetic member of the mounting plate magnetically attracts the magnetic member or ferromagnetic metal of the second base plate.

[0015] The present invention also proposes a desktop printer, including a frame, a printing component and the aforementioned fixture-type printing platform, wherein the printing component and the fixture-type printing platform are both mounted on the frame, and the printhead of the printing component is positioned facing the fixture-type printing platform.

[0016] The technical solution of this invention employs a fixture base and a first fixture. The fixture base is equipped with an actuating gear driven by a driving component, while the first fixture integrates a gear set and a rotating component, and is detachably mounted on a mounting plate of the fixture base via a housing, allowing the gear set to mesh with the actuating gear for transmission. Compared to the traditional method relying on frictional transmission between a roller fixture and the printing platform, this solution avoids transmission errors caused by frictional slippage between the fixture base and the first fixture by using a gear meshing transmission mechanism. Thus, the driving component drives the actuating gear, which in turn drives the gear set to rotate, thereby causing the rotating component to rotate. The outer circumference of the rotating component abuts against the surface of the product, and the friction between them drives the product to rotate, achieving continuous rotary feed during the printing process. This working method of the fixture base and the first fixture reduces the original two-stage frictional transmission to a single-stage frictional transmission, reducing the slippage error accumulated by the two-stage frictional transmission, thereby improving the printing accuracy of the product and effectively suppressing the problem of pattern printing offset.

[0034] Desktop printers, as an important branch of miniaturized, high-precision printing equipment, have developed rapidly in recent years due to the rapid growth in demand for personalized customization and small-batch production. Their technological evolution has progressed from initially supporting only flat surface printing to gradually expanding to printing on curved, cylindrical, and other irregularly shaped surfaces, meeting the decorative and labeling needs of everyday items such as cups and pen holders. To achieve stable printing on non-planar objects, the industry has widely introduced roller fixture structures, which convert the linear motion of the printing platform into the rotational motion of the object being printed through mechanical transmission, thereby achieving continuous and uniform pattern coverage.

[0035] Currently, mainstream desktop printers typically use a roller fixture combined with friction drive when printing cylindrical products. Specifically, as the printing platform moves, the friction between its surface and the rollers drives the rollers to rotate around their own axis; the rollers, in turn, cause the cylindrical product to rotate synchronously through contact friction with the product's outer surface, thus "wrapping" the pattern printed by the printhead along a straight path onto the product's surface. This solution is simple in structure, low in cost, and allows for quick replacement of fixtures of different sizes, hence its widespread adoption.

[0036] However, current printing platforms and roller fixtures are prone to printing misalignment during the printing process. Experimental research has revealed a transmission accuracy issue with the aforementioned printing method. Since the transmission between the roller and the cylindrical product, and between the roller and the printing platform, relies on friction, this friction transmission inherently carries the risk of slippage. Furthermore, the secondary friction transmission between the roller and the cylindrical product, and between the roller and the printing platform, further amplifies the error, easily leading to printing misalignment.

[0037] To address the above problems, this invention proposes a fixture-type printing platform.

[0038] Please see Figures 1 to 2 In one embodiment of the present invention, the fixture-type printing platform is applied to a desktop printer. The fixture-type printing platform includes a fixture base 1 and a first fixture 2. The fixture base 1 includes a mounting plate 11, a driving component 12, and an actuating gear 13. The driving component 12 is mounted on the mounting plate 11 and is connected to the actuating gear 13 in a transmission manner. The first fixture 2 includes a housing 21, a gear set 22, and a rotating component 23. The gear set 22 and the rotating component 23 are both rotatably mounted on the housing 21. The gear set 22 is connected to the rotating component 23 in a transmission manner. The outer periphery of the rotating component 23 is used to abut against the product. The housing 21 is detachably mounted on the mounting plate 11 so that the gear set 22 meshes with the actuating gear 13.

[0039] The technical solution of this invention employs a fixture base 1 and a first fixture 2. The fixture base 1 is equipped with an actuating gear 13 driven by a driving component 12, while the first fixture 2 integrates a gear set 22 and a rotating component 23, and is detachably mounted on the mounting plate 11 of the fixture base 1 via a housing 21, allowing the gear set 22 to mesh and transmit power with the actuating gear 13. Compared to the traditional method relying on frictional transmission between a roller fixture and the printing platform, this solution avoids transmission errors caused by frictional slippage between the fixture base 1 and the first fixture 2 by using a gear meshing transmission mechanism. Thus, the driving component 12 drives the actuating gear 13, which in turn drives the gear set 22 to rotate, thereby causing the rotating component 23 to rotate. The outer periphery of the rotating component 23 is used to abut against the surface of the product, and the friction between the two drives the product to rotate, achieving continuous rotary feed during the printing process. The working method of the fixture base 1 and the first fixture 2 can reduce the original two-stage friction transmission to a single-stage friction transmission, thereby reducing the slippage error accumulated by the two-stage friction transmission, thus improving the printing accuracy of the product and effectively suppressing the problem of pattern printing offset.

[0040] In addition, the housing 21 and the mounting plate 11 are detachably connected, which makes it easy to quickly change the appropriate fixture according to different types of products, such as using the first fixture 2 or other fixtures. This balances the convenience of high-precision printing and fixture replacement, meeting the stringent requirements of transmission accuracy for printing on irregular surfaces, while retaining the flexibility and practicality of desktop printers in small-batch, multi-variety production scenarios.

[0041] It should be noted that the first fixture 2 in this embodiment is suitable for products with arc-shaped outer surfaces, such as cylindrical and spherical shapes. The first fixture 2 can contact the outer surface of the product through the outer periphery of the rotating component 23, and drive the product to rotate through the contact friction force by the rotation of the rotating component 23, thereby realizing the continuous rotational feeding of the product during the printing process.

[0042] Furthermore, the drive component 12 can be configured as a drive device capable of generating torque, such as a motor, and the actuating gear 13 can be connected to the rotating shaft of the motor for transmission, which will not be elaborated further here. Specifically, the actuating gear 13 can directly mesh with the gear set 22 to achieve gear transmission; alternatively, the actuating gear 13 can mesh with the gear set 22 through an additional transmission gear to achieve gear transmission (see reference...). Figure 2 (This is not limited to)

[0043] In addition, the mounting plate 11 can be a single piece of integrally formed plate, or it can be composed of multiple plates connected together. In the case where the mounting plate 11 is composed of multiple plates connected together, different plates can have different functions. For example, the lower plate is an adjustment plate with leveling components such as adjusting bolts and nuts, and the upper plate is a mounting plate. The adjustment plate is connected to the mounting plate through the leveling components. In this way, the upper mounting plate can be leveled by adjusting the leveling components, thereby achieving a higher precision printing effect for the product.

[0044] Please see Figures 1 to 2 In an embodiment of the present invention, the rotating assembly 23 includes at least two drive shafts 231 and a plurality of jig rollers 232. The drive shafts 231 are rotatably mounted on the housing 21. The at least two drive shafts 231 are spaced apart from each other. The drive shafts 231 are connected to the gear set 22. A plurality of jig rollers 232 are spaced apart along the axial direction on the outer periphery of each drive shaft 231. An elastic sealing ring 233 is provided on the outer periphery of the jig rollers 232. The elastic sealing ring 233 is used to abut against the product.

[0045] In this embodiment, the rotating assembly 23 includes at least two drive shafts 231 and multiple jig rollers 232. The at least two drive shafts 231 are spaced apart from each other and are rotatably mounted on the housing 21. This allows the multiple drive shafts 231 to work together to transmit the driving force from the gear set 22, making the power distribution more uniform and effectively improving the overall transmission stability and load capacity of the rotating assembly 23. In addition, multiple jig rollers 232 are spaced apart along the axial direction on the outer periphery of each drive shaft 231. The multiple jig rollers 232 arranged along the axial direction can form multi-point support and drive in the length direction of the product, which significantly enhances the clamping stability of the product. This is especially suitable for long or easily deformable cylindrical products, preventing them from shaking or deflecting due to uneven local force during the printing process. In addition, the jig roller 232 is provided with an elastic sealing ring 233 on its outer periphery. The elastic sealing ring 233 is used to abut against the product surface. The setting of the elastic sealing ring 233 not only increases the coefficient of friction with the product surface and improves the reliability of friction transmission, but also can adapt to products with different diameters or surface roughness, playing a dual role of buffering and anti-slip. Furthermore, the flexible contact of the elastic sealing ring 233 can reduce the risk of scratching the product surface and protect the appearance integrity of the printed pattern on the product.

[0046] The drive shaft 231 is rotatably mounted on the housing 21. Specifically, the housing 21 has at least two openings, and bearings are installed in the openings. Different drive shafts 231 are installed in different bearings, thereby realizing the rotatable mounting of the drive shaft 231.

[0047] Please see Figures 1 to 2 In an embodiment of the present invention, the gear set 22 includes a main drive gear 221 and at least two auxiliary drive gears 222. The main drive gear 221 is rotatably mounted on the housing 21, and the at least two auxiliary drive gears 222 are correspondingly and fixedly connected to at least two drive shafts 231. The auxiliary drive gears 222 mesh with the main drive gear 221. The bottom teeth of the main drive gear 221 protrude from the lower surface of the housing 21, and the top teeth of the actuating gear 13 are lower than or flush with the upper surface of the mounting plate 11.

[0048] In this embodiment, the gear set 22 includes a main drive gear 221 and at least two auxiliary drive gears 222. The main drive gear 221 is rotatably mounted on the housing 21. The at least two auxiliary drive gears 222 are respectively fixedly connected to at least two drive shafts 231, and each auxiliary drive gear 222 meshes with the main drive gear 221, thereby synchronously and evenly distributing the rotational motion of the main drive gear 221 to multiple drive shafts 231. Since the dimensional parameters of each auxiliary drive gear 222 are consistent, it can ensure that the rotational speed of each drive shaft 231 is consistent, effectively avoiding the problem of asynchronous product rotation caused by uneven power distribution, and improving the coordination and stability of product rotation during the printing process. Furthermore, the bottom teeth of the main drive gear 221 protrude from the lower surface of the housing 21, while the top teeth of the actuating gear 13 are lower than or flush with the upper surface of the mounting plate 11. This structural design allows the main drive gear 221 and the actuating gear 13 to mesh properly after the first fixture 2 is installed at the corresponding position on the fixture base 1, making the installation operation simple. At the same time, this tooth layout not only effectively prevents foreign objects from entering the meshing area, improving the reliability and service life of the transmission system, but also prevents the actuating gear 13 from protruding from the upper surface of the mounting plate 11, thereby facilitating the installation of the mounting plate 11 with other fixtures that do not require gear transmission, and enabling the fixture base 1 to adapt to different types of fixtures.

[0049] The specific installation method of the main drive gear 221 rotatably mounted on the housing 21 can refer to the above-mentioned rotatable installation method, that is, the housing 21 is provided with an opening, and a rotating shaft is provided in the opening. The inner circumference of the main drive gear 221 is sleeved on the rotating shaft, thereby realizing the rotatable installation of the main drive gear 221.

[0050] Please see Figure 3 In an embodiment of the present invention, the top of the mounting plate 11 is provided with a positioning recess (not shown in the figure), and the bottom of the outer shell 21 is provided with a positioning protrusion, which is positioned and engaged with the positioning recess; or, the mounting plate 11 is provided with a positioning notch 111 around its perimeter, and the bottom perimeter of the outer shell 21 is provided with a positioning protrusion 211, which is positioned and engaged with the positioning notch 111.

[0051] In this embodiment, the top of the mounting plate 11 is provided with a positioning recess, and the bottom of the outer shell 21 is provided with a matching positioning protrusion 211. The two work together to achieve precise alignment of the first fixture 2 during the installation process of the outer shell 21. Alternatively, the mounting plate 11 is provided with positioning notches 111 around its perimeter, and the bottom perimeter of the outer shell 21 is provided with corresponding positioning protrusions 211. The positioning protrusions 211 are embedded in the positioning notches 111, which also achieves quick and accurate installation positioning. Any of the above structures can effectively limit the lateral displacement of the first fixture 2 on the mounting plate 11, ensuring that the main drive gear 221 in the gear set 22 and the actuating gear 13 on the fixture base 1 mesh precisely after installation, avoiding problems such as poor meshing, transmission jamming, or gear wear caused by installation misalignment. At the same time, this positioning structure does not require complex auxiliary tools or repeated manual adjustments, significantly improving the efficiency and ease of operation of fixture replacement.

[0052] In one optional implementation, the positioning recess can be a positioning groove or a positioning hole, such as a pin hole; correspondingly, the positioning protrusion 211 is a protrusion that matches the shape of the positioning recess. For example, when the positioning recess is a cuboid positioning groove, the positioning protrusion 211 is a cuboid protrusion corresponding to the positioning groove. When the positioning recess is a pin hole, the positioning protrusion 211 can be a pin-shaped protrusion.

[0053] In an embodiment of the present invention, the top of the mounting plate 11 is provided with a magnetic element, and the bottom of the outer shell 21 is provided with a magnetic element or ferromagnetic metal. The magnetic element of the mounting plate 11 and the magnetic element or ferromagnetic metal of the outer shell 21 are magnetically attracted to each other.

[0054] In this embodiment, the top of the mounting plate 11 is equipped with a magnetic component, and the bottom of the outer casing 21 is equipped with a magnetic component or ferromagnetic metal. The two components are magnetically attracted to each other to achieve quick connection and positioning between the first fixture 2 and the mounting plate 11. This magnetic structure can automatically attract and fix the first fixture 2 when it is placed on the mounting plate 11, effectively limiting its lateral or vertical displacement caused by vibration or external force interference during the printing process. This ensures the stable meshing state of the main drive gear 221 and the actuating gear 13, avoiding transmission errors or gear damage caused by loosening. At the same time, the magnetic attraction method not only makes installation and disassembly simple, but also reduces wear on the connecting structure caused by frequent disassembly and reassembly, extending the service life of the fixture and the base. In addition, the magnitude of the magnetic attraction force can be designed according to actual needs by using different magnetic component materials. While ensuring connection reliability, it is still easy for users to change the fixture by hand, thereby ensuring operational flexibility and efficiency.

[0055] As an optional implementation, the magnetic component can be a magnet, and the ferromagnetic metal can include one or more materials such as iron, cobalt, and nickel.

[0056] Please see Figure 1 and Figure 4 In an embodiment of the present invention, the fixture-type printing platform further includes a second fixture 3, which includes at least a mobile phone case receiving shell 31. The mobile phone case receiving shell 31 is detachably mounted on the mounting plate 11. A receiving groove 311 is provided on the top of the mobile phone case receiving shell 31 for receiving a mobile phone case.

[0057] In this embodiment, the jig-type printing platform also includes a second jig 3, which includes at least a phone case receiving shell 31. The phone case receiving shell 31 is detachably mounted on the mounting plate 11, and its top has a receiving groove 311 for receiving the phone case. This structure provides limiting and stable support for the phone case by setting the phone case receiving groove 311, preventing it from moving during the printing process, thereby ensuring the positional accuracy and integrity of the printed pattern. At the same time, since the phone case receiving shell 31 is detachably mounted on the mounting plate 11, the user can quickly switch between the first jig 2 and the second jig 3 according to the type of printing object, realizing the adaptation of cylindrical products and phone case products without replacing the entire printing platform, significantly improving the versatility and production efficiency of the equipment. In addition, the shape and size of the receiving groove 311 can be customized according to different models of phone cases, ensuring adaptability while facilitating consistent positioning during batch printing.

[0058] Please see Figures 4 to 5 In an embodiment of the present invention, the receiving groove 311 is provided with a boss 312 and at least two movable clamping members 313. At least two elastic members 314 are provided on at least two side surfaces of the boss 312. The clamping members 313 are elastically connected to the boss 312 through the elastic members 314. The elastic members 314 are used to apply an elastic force to the clamping members 313 in the direction of the edge of the receiving groove 311.

[0059] In this embodiment, the receiving groove 311 is provided with a boss 312 and at least two movable clamping members 313. The boss 312 serves as the supporting core of the clamping structure, providing a stable mounting base for the clamping members 313 and the elastic members 314, ensuring reliable transmission of clamping actions. Furthermore, at least two elastic members 314 are correspondingly provided on at least two side surfaces of the boss 312. The clamping members 313 are elastically connected to the boss 312 through the elastic members 314. The elastic members 314 apply an elastic force to the clamping members 313 towards the edge of the receiving groove 311. Thus, the movable clamping members 313 can move flexibly in the horizontal direction under the drive of the elastic members 314, adapting to phone cases of different widths or contours and achieving adaptive clamping. Specifically, by continuously applying an elastic force towards the edge of the receiving groove 311, the elastic members 314 ensure that the clamping members 313 always conform to the side wall of the phone case, not only improving the positioning stability of the phone case but also effectively resisting minor displacements caused by platform movement or nozzle vibration during printing. Furthermore, since the clamping force is provided by the elastic element 314, the clamping process has elastic buffering characteristics, which can prevent rigid clamping from causing indentations or scratches on the surface of the phone case. Overall, through the coordinated cooperation of the boss 312, the movable clamping element 313, and the elastic element 314, this clamping structure achieves automatic adaptation and stable positioning for various models of phone cases, while taking into account clamping reliability and product surface protection, significantly improving the positioning consistency and printing yield of the second fixture 3 in batch printing.

[0060] In one optional implementation, the elastic element 314 can be a spring, an elastic rubber ring, or the like; the clamping element 313 can be a clamping block. Furthermore, the edge of the receiving groove 311 can be provided with a protruding mating portion, allowing the clamping element 313 to cooperate with the protruding mating portion to jointly clamp the phone case.

The mounting plate 11 is provided with a first opening 112, and the first base plate 32 is provided with a second opening 321. The fixture-type printing platform further includes a positioning member (not shown in the figure), which passes through the second opening 321 and the first opening 112 in sequence to position the mounting plate 11 and the first base plate 32 in a positioning fit. The first base plate 32 is provided with a magnetic member (not shown in the figure) or a ferromagnetic metal (not shown in the figure), and the magnetic member of the mounting plate 11 is magnetically attracted to the magnetic member or ferromagnetic metal of the first base plate 32.

[0062] In this embodiment, the second fixture 3 also includes a first base plate 32 and a first height compensation component 33. The first base plate 32 is detachably mounted on the mounting plate 11. By setting the first base plate 32 as an intermediate connecting layer, it is convenient to uniformly adapt fixture modules with different functions (such as the mobile phone case housing 31) to the same mounting plate 11, thereby improving the modularity and assembly flexibility of the fixture system. The first height compensation component 33 is mounted on the first base plate 32 and is used to adjust the installation height of the mobile phone case housing 31 in the vertical direction, thereby compensating for the height deviation caused by the difference in working distance of different printheads or product thickness, ensuring that the printing surface of the mobile phone case is always within the optimal focusing plane of the printhead, and improving printing clarity and accuracy. In addition, the mounting plate 11 is provided with a first opening 112, and the first base plate 32 is provided with a second opening 321. The fixture-type printing platform also includes a positioning component, which passes through the second opening 321 and the first opening 112 in sequence, so that the mounting plate 11 and the first base plate 32 can achieve precise positioning and engagement, effectively preventing the first base plate 32 from shifting laterally or rotating during installation, and ensuring the positional repeatability accuracy of the phone case housing 31. At the same time, the first base plate 32 is provided with a magnetic component or ferromagnetic metal, which forms a magnetic attraction with the magnetic component on the mounting plate 11. This magnetic attraction structure further enhances the connection stability between the first base plate 32 and the mounting plate 11 on the basis of the initial alignment of the positioning component, preventing the base plate from loosening due to vibration during printing, and making it easy for users to quickly assemble and disassemble by hand, taking into account both positioning reliability and operation convenience. Overall, through the coordinated design of the first base plate 32, the first height compensation component 33, the positioning component, and the magnetic attraction, this structure not only achieves flexible adjustment and high-precision positioning of the printing height of the mobile phone case, but also improves the adaptability and installation stability of the second fixture 3 in switching between multiple product models, effectively ensuring the consistency of printing quality and the high efficiency of equipment use.

[0063] The first height compensation component 33 can be a structural component in the shape of a plate, block, column, or cuboid, etc., and has a certain length in the height direction, thereby adjusting the installation height of the phone case housing 31 in the vertical direction. In addition, the positioning component can be set as a pin, and the first opening 112 is a pin hole, so that the mounting plate 11 and the first base plate 32 can achieve precise positioning and engagement.

[0064] Please see Figure 1 , Figure 6 and Figure 7In an embodiment of the present invention, the fixture-type printing platform further includes a third fixture 4, which includes a second base plate 41, a second height compensation member 42, and a placement platform 43. The second base plate 41 is detachably mounted on the mounting plate 11, the second height compensation member 42 is mounted on the second base plate 41, and the placement platform 43 is mounted on the second height compensation member 42. The mounting plate 11 is provided with a first opening 112, and the second base plate 41 is provided with a third opening 411. The fixture-type printing platform also includes a positioning member (not shown in the figure), which passes through the third opening 411 and the first opening 112 in sequence to position the mounting plate 11 and the second base plate 41 in a positioning fit. The second base plate 41 is provided with a magnetic member (not shown in the figure) or a ferromagnetic metal (not shown in the figure), and the magnetic member of the mounting plate 11 is magnetically attracted to the magnetic member or ferromagnetic metal of the second base plate 41.

[0065] In this embodiment, the jig-type printing platform also includes a third jig 4, which includes a second base plate 41, a second height compensation component 42, and a placement platform 43. The second base plate 41 is detachably mounted on the mounting plate 11. By setting the second base plate 41 as a universal mounting base, it is convenient to quickly integrate printing jigs (such as the placement platform 43) suitable for planar or irregular non-cylindrical products into the same jig base 1 system, thereby improving the compatibility and modular expansion capability of the whole machine for multiple types of products. The second height compensation component 42 is mounted on the second base plate 41 and is used to adjust the installation height of the placement platform 43 in the vertical direction, thereby adapting to printing objects of different thicknesses or different nozzle working focal lengths, ensuring that the printing surface is always in the optimal imaging and spraying position, and ensuring the clarity and adhesion quality of the printed pattern. The placement platform 43 is used to place planar products, thereby realizing the printing of planar products. In addition, the mounting plate 11 has a first opening 112, and the second base plate 41 has a third opening 411. The fixture-type printing platform also includes a positioning component, which passes through the third opening 411 and the first opening 112 in sequence, so that the mounting plate 11 and the second base plate 41 can achieve a high-precision mechanical positioning fit, effectively avoiding lateral offset or angular deviation of the second base plate 41 during installation, ensuring that the placement platform 43 can maintain a consistent spatial position after multiple assembly and disassembly, and improving the repeatability of the printing operation. At the same time, the second base plate 41 is provided with a magnetic component or ferromagnetic metal, which forms a magnetic attraction fit with the magnetic component on the mounting plate 11. This magnetic attraction structure further enhances the connection rigidity between the second base plate 41 and the mounting plate 11 on the basis of the initial alignment completed by the positioning component, effectively resisting slight loosening caused by platform movement or equipment vibration during printing, and supporting users to quickly complete the installation and replacement by hand, significantly improving the operating efficiency. Overall, the third fixture 4, through the coordinated design of the second base plate 41, the second height compensation component 42, the positioning component, and the magnetic attraction, not only achieves flexible height adjustment and high-precision positioning of planar printing objects, but also enhances the versatility, stability, and ease of use of the fixture-type printing platform in diverse product printing scenarios.

[0066] The second base plate 41 can be a plate with the same structure as the first base plate 32; the second height compensation member 42 can be a component with the same structure as the first height compensation member 33, which will not be described in detail here. In addition, the positioning member can be set as a pin, and the first opening 112 is a pin hole, so that the mounting plate 11 and the first base plate 32 can achieve precise positioning and engagement.
