Description

A customizable phone case vending machine Technical Field

[0001] This invention relates to the field of mobile phone case technology, and specifically to a custom mobile phone case vending machine. Background Technology

[0002] With the development of technology and the widespread use of smartphones, people typically use phone cases to protect and decorate their smartphones, making them more personalized. Unmanned phone case vending machines usually have printing devices to print designs on the cases, allowing users to customize their phone cases.

[0003] Because users use a variety of mobile phone models with varying thicknesses, the corresponding thickness of phone cases also varies. However, after the vending machine's robotic arm places the phone case into the positioning structure of the printing device, it does not adjust the height of the phone case. This results in some overly thick phone cases being too close to the print head during the printing process, which may affect the printing effect or even cause collisions with the print head. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a custom mobile phone case vending machine.

[0005] One embodiment of the present invention provides a custom mobile phone case vending machine, comprising: a frame, a mobile phone case printing device, and a mobile phone case storage and handling mechanism;

[0006] The rack is equipped with multiple cargo compartments;

[0007] The phone case printing device is located on one side of the phone case storage and handling mechanism, which transports phone cases between the warehouse and the phone case printing device.

[0008] The mobile phone case printing device includes a printing mechanism, a mobile phone case shaping fixture, a height adjustment mechanism, and a conveying mechanism.

[0009] The printing mechanism is mounted on the frame and is used to print on mobile phone cases;

[0010] The phone case shaping fixture is arranged below the printing mechanism and is used to position the phone case;

[0011] The height adjustment mechanism is driven to the phone case shaping fixture. The height adjustment mechanism drives the phone case shaping fixture to rise and fall so that the phone case on the phone case shaping fixture is at a preset height relative to the printing mechanism.

[0012] In some alternative implementations, the height adjustment mechanism includes:

[0013] A lifting drive assembly is connected to the phone case shaping fixture drive assembly and is used to drive the phone case shaping fixture to lift.

[0014] A height detection component is used to detect whether the phone case has reached a preset height. The height detection component is arranged on one side of the phone case shaping fixture and is signal-connected to the lifting drive component.

[0015] In some optional embodiments, the mobile phone case printing device further includes a conveying mechanism, which is disposed on the frame and drivenly connected to the height adjustment mechanism, driving the height adjustment mechanism to move relative to the printing mechanism to the feeding position and the printing position;

[0016] Specifically, when the conveying mechanism drives the height adjustment mechanism to move from the loading position to the printing position, if the height detection component detects a phone case at the preset height, the lifting drive component drives the phone case shaping fixture to descend until the height detection component no longer detects a phone case at the preset height. If the height detection component does not detect a phone case at the preset height, the lifting drive component drives the phone case shaping fixture to rise until the height detection component detects a phone case at the preset height. Then, the lifting drive component drives the phone case shaping fixture to descend again until the height detection component no longer detects a phone case at the preset height.

[0017] In some optional embodiments, the mobile phone case storage and handling mechanism includes a multi-axis translation drive assembly, a rotation drive assembly, and an adsorption assembly;

[0018] The multi-axis translation drive component is driven to the adsorption component and is used to drive the adsorption component to translate.

[0019] The rotation drive assembly is driven to the adsorption assembly and is used to drive the adsorption assembly to rotate to both sides of the multi-axis translation drive assembly.

[0020] The adsorption component is used to grip the phone case;

[0021] Multiple cargo compartments are arranged on both sides of the multi-axis translation drive assembly, with some cargo compartments and the mobile phone case printing device located on the same side of the multi-axis translation drive assembly, and other cargo compartments and the mobile phone case printing device located on opposite sides of the multi-axis translation drive assembly.

[0022] [Correction 25.08.2025 according to Rule 91] In some optional embodiments, the frame is provided with a discharge bin, the discharge bin and the mobile phone case printing device are arranged on the same side of the mobile phone case storage and handling mechanism, and the top of the discharge bin is provided with a feed inlet.

[0023] The mobile phone case storage and handling mechanism moves the mobile phone cases between the warehouse, the printing mechanism, and the discharge hopper.

[0024] In some alternative embodiments, the frame is provided with support beams;

[0025] The printing mechanism includes a printhead assembly, a printhead drive assembly, and a position detection assembly;

[0026] The support beam is equipped with a nozzle guide rail;

[0027] The printhead assembly is movably connected to the printhead guide rail, and the printhead assembly and the position detection assembly are respectively disposed on both sides of the support beam;

[0028] The printhead drive assembly is driven by the printhead assembly, and drives the printhead assembly to move along the printhead guide track.

[0029] In some alternative embodiments, the position detection component includes a grating sensor and a grating strip, the grating sensor and the grating strip being inductively coupled, both the grating sensor and the grating strip being arranged on the side of the support beam away from the print head assembly, the grating sensor being connected to the print head assembly, and the grating strip being disposed on the side of the support beam away from the print head assembly.

[0030] In some alternative embodiments, the printing mechanism further includes a protective cover that surrounds and forms a printing space located on the side of the support beam facing the printhead assembly and below the printhead assembly;

[0031] When the printing mechanism prints a mobile phone case, the mobile phone case shaping fixture is located within the printing space.

[0032] In some alternative embodiments, the phone case shaping fixture includes a phone case shaping base and a positioning component;

[0033] The positioning component is disposed on the phone case shaping base and is used to push the phone case to a preset shaping position on the phone case shaping base;

[0034] The positioning component includes a positioning drive component and four positioning elements. The four positioning elements are disposed on the phone case shaping base and are respectively located on the four sides of the shaping position.

[0035] The positioning drive component drives the positioning members located on both sides adjacent to the shaping position to move relative to the phone case shaping base; or, the positioning drive component drives the positioning members located on three sides adjacent to the shaping position to move relative to the phone case shaping base; or, the positioning drive component drives four positioning members to move relative to the phone case shaping base, so that the corresponding positioning members move closer to or further away from the shaping position.

[0036] In some optional embodiments, the positioning drive assembly is driven to connect with the positioning elements located on at least two sides adjacent to the shaping position, wherein the positioning element connected to the positioning drive assembly is a movable positioning element, and the movable positioning element is movably connected to the phone case shaping base.

[0037] Compared to existing technologies, the mobile phone case customization unmanned vending machine of this invention significantly increases the number of storage compartments through the rational layout of various structures, effectively utilizing space. The mobile phone case storage and handling mechanism can stably adsorb mobile phone cases through the adsorption component, achieving stable gripping. The multi-axis translational drive component and the rotational drive component can drive the adsorption component to move flexibly, facilitating product retrieval. Furthermore, a larger number of storage compartments can be arranged, resulting in a more streamlined overall structure. The mobile phone case printing device has a simple overall structure, provides accurate printing with good results, and effectively addresses problems encountered during the mobile phone case printing process. For example, the height of the mobile phone case can be adjusted through the height adjustment mechanism to maintain a suitable distance between the mobile phone case and the printing mechanism. The spacing is optimized to avoid the impact of thickness differences between different phone cases on printing results; the positioning component can stably position the phone case, ensuring it accurately reaches the shaping position for subsequent printing. The structure is simple, eliminating the need for additional positioning sleeves on the outside of the phone case, thus reducing production and transportation costs; by placing the printhead assembly and position detection assembly on opposite sides of the support beam, the filament ejected from the printhead assembly is prevented from adhering to the position detection assembly, effectively avoiding contamination and reducing maintenance frequency; the conveying mechanism can transport the phone case shaping fixture, preventing the printing mechanism from interfering with the handling of the phone case.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0066] Please refer to Figures 1 and 2. One embodiment of the present invention provides a mobile phone case customization unmanned vending machine, including: a frame 10, a mobile phone case storage and handling mechanism 20, and a mobile phone case printing device 30.

[0067] Multiple cargo compartments 11 are provided on the rack 10.

[0068] The phone case printing device 30 is located on one side of the phone case storage and handling mechanism 20, which moves the phone cases between the warehouse 11 and the phone case printing device 30.

[0069] To facilitate the installation of the phone case printing device 30, a bracket 40 is also provided on the frame 10. The bracket 40 is detachably connected to the frame 10, and the phone case printing device 30 is mounted on the bracket 40, forming a modular design between the phone case printing device 30 and the bracket 40. This facilitates production assembly and subsequent disassembly, maintenance, and replacement. The phone case printing device 30 includes a printing mechanism 50, a phone case shaping fixture 60, a height adjustment mechanism 70, and a conveying mechanism 80.

[0070] The printing mechanism 50 is mounted on the bracket 40 and is used to print on the phone case.

[0071] The phone case shaping fixture 60 is arranged below the printing mechanism 50 and is used to position the phone case.

[0072] The height adjustment mechanism 70 is driven to connect to the phone case shaping fixture 60. The height adjustment mechanism 70 drives the phone case shaping fixture 60 to rise and fall so that the phone case on the phone case shaping fixture 60 is at a preset height relative to the printing mechanism 50.

[0073] The following explains the operating principle of the custom phone case vending machine: After the phone case storage and handling mechanism 20 takes the phone case out of the warehouse 11, it places the phone case on the phone case shaping fixture 60. The phone case shaping fixture 60 positions the phone case, and then the height adjustment mechanism 70 adjusts the height of the phone case shaping fixture 60 so that the phone case is at a preset height suitable for printing by the printing mechanism 50. After printing is completed, the phone case storage and handling mechanism 20 removes the phone case from the phone case shaping fixture 60 and then moves the phone case to a suitable location so that the user can pick up the printed phone case.

[0074] Please refer to Figures 3 and 4. In some optional embodiments, the mobile phone case storage and handling mechanism 20 includes a multi-axis translation drive assembly 210, a rotation drive assembly 220, and an adsorption assembly 230.

[0075] The multi-axis translation drive assembly 210 is driven to the adsorption assembly 230 and is used to drive the adsorption assembly 230 to translate.

[0076] The rotary drive assembly 220 is driven to the adsorption assembly 230 and is used to drive the adsorption assembly 230 to rotate to both sides of the multi-axis translation drive assembly 210.

[0077] Adsorption component 230 is used to grip the phone case;

[0078] Multiple cargo compartments 11 are arranged on both sides of the multi-axis translation drive assembly 210. Some of the cargo compartments 11 and the mobile phone case printing device 30 are located on the same side of the multi-axis translation drive assembly 210, while other cargo compartments 11 and the mobile phone case printing device 30 are located on opposite sides of the multi-axis translation drive assembly 210.

[0079] The multi-axis translation module can move the adsorption component 230 to one side of any of the storage compartments 11. Then, the rotation drive component 220 drives the adsorption component 230 to rotate towards the storage compartment 11, so that the adsorption component 230 moves to the outlet of the storage compartment 11. The adsorption component 230 can enter the storage compartment 11 under the drive of the adsorption component 230 or the multi-axis translation module, so that the adsorption component 230 adsorbs the mobile phone cases located in the storage compartment 11, thereby grasping the mobile phone cases. Then, the adsorption component 230 detaches from the storage compartment 11 under the drive of the adsorption component 230 or the multi-axis translation module. The adsorption component 230 can stably adsorb mobile phone cases, achieving stable grasping. The multi-axis translation module and the rotation drive component 220 can drive the adsorption component 230 to move flexibly, facilitating goods retrieval, and allowing for the deployment of a large number of storage compartments 11.

[0080] Since the adsorption component 230 can move to both sides of the multi-axis translation drive component 210 under the drive of the rotation drive component 220, the cargo compartment 11 can be arranged on both sides of the multi-axis translation drive component 210, which increases the space available for the cargo compartment 11, increases the number of mobile phone cases that can be stored, and also makes the structure more compact.

[0081] Referring to Figure 5, in some optional embodiments, a discharge bin 12 is provided on the frame 10. The phone case printing device 30 is arranged on the same side of the phone case storage and handling mechanism 20. A feed inlet 121 is provided on the top of the discharge bin 12. The phone case storage and handling mechanism 20 transports the phone case between the storage bin 11, the printing mechanism 50, and the discharge bin 12. Since the phone case printing device 30 and the discharge bin 12 occupy relatively little space, by adding storage bins 11 on both sides of the multi-axis translation drive assembly 210, the available space of the storage bins 11 can be increased, the number of phone cases that can be stored can be increased, and the structure can be made more compact. After printing is completed, the phone case storage and handling mechanism 20 removes the phone case from the phone case shaping fixture 60, then transports the phone case above the discharge bin 12, and then lowers the phone case so that it falls into the discharge bin 12 from the feed inlet 121. The user then receives the printed phone case from the discharge bin 12. In this embodiment, a material retrieval port for the user to reach into is provided on one side of the discharge bin 12.

[0082] In some optional embodiments, an inclined guide plate 122 is provided on the side of the feed inlet 121 facing the multi-axis translation drive assembly 210. The inclined guide plate 122 gradually tilts downward away from the multi-axis translation drive assembly 210. The adsorption assembly 230 moves above the inclined guide plate 122 under the drive of the multi-axis translation drive assembly 210 and the rotation drive assembly 220. Then, the adsorption assembly 230 puts down the gripped mobile phone case. The mobile phone case falls onto the inclined guide plate 122 and is then guided by the inclined guide plate 122 through the feed inlet 121 and into the discharge chamber 12. The user can then remove the mobile phone case from the discharge chamber 12. The inclined guide plate 122 facilitates the tilting of the mobile phone case away from the multi-axis translation drive assembly 210 before it enters the discharge chamber 12. This allows the other structures of the discharge chamber 1214, except for the inclined guide plate 122, to be arranged at a position further away from the multi-axis translation drive assembly 210 to avoid interference with the multi-axis translation drive assembly 210.

[0083] The specific structure of the multi-axis translation drive assembly 210 can be selected according to actual needs. For example, in some optional embodiments, the multi-axis translation drive assembly 210 includes a first translation drive module 211 and a second translation drive module 212. The first translation drive module 211 is driven to the adsorption assembly 230 and is used to drive the adsorption assembly 230 to move in a first direction. The second translation drive module 212 is driven to the adsorption assembly 230 and is used to drive the adsorption assembly 230 to move in a second direction. The first direction and the second direction are perpendicular to each other. A plurality of cargo bins 11 are arranged on at least one side of the first translation drive module 211. In this embodiment, the cargo bins 11 are arranged in a matrix in the first and second directions, thereby facilitating the multi-axis translation drive assembly 210 to accurately drive the adsorption assembly 230 to one side of the cargo bins 11. In this embodiment, the cargo bins 11, the mobile phone case printing device 30, and the discharge bin 12 are distributed on both sides of the first translation drive module 211, effectively utilizing the space on both sides of the first translation drive module 211.

[0084] In some optional embodiments, the multi-axis translation drive assembly 210 further includes a third translation drive module, which is drivenly connected to the adsorption assembly 230 and used to drive the adsorption assembly 230 to move in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. When the locations on both sides of the first translation drive module 211, where the storage compartment 11, the printing station, or the discharge station are far apart, adding the third translation drive module can facilitate the movement of the adsorption assembly 230 to the storage compartment 11, the printing station, or the discharge station. In this embodiment, the first direction is the front-back direction of the frame 10, the second direction is the vertical direction of the frame 10, and the third direction is the left-right direction of the frame 10, but this is not a limitation.

[0085] The specific structures of the first translation drive module 211, the second translation drive module 212, and the third translation drive module can be designed according to actual needs. For example, the first translation drive module 211, the second translation drive module 212, and the third translation drive module can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc. In this embodiment, both the first translation drive module 211 and the second translation drive module 212 adopt belt translation drive components. The frame 10 is provided with a first guide rail extending in a first direction, a first support seat slidably engaged with the first guide rail, a second guide rail extending in a second direction, and a second support seat slidably engaged with the second guide rail. The first translation drive module 211 is mounted on the frame 10, and the belt of the first translation drive module 211 is drivenly connected to the first support seat. The second translation drive module 212 is mounted on the first support seat, and the belt of the second translation drive module 212 is drivenly connected to the second support seat. The rotation drive component 220 is mounted on the second support seat and then drivenly connected to the adsorption component 230. The first translation drive module 211 drives the first support seat to move, thereby driving the adsorption component 230 to move in the first direction. The second translation drive module 212 drives the second support seat to move, thereby driving the adsorption component 230 to move in the second direction.

[0086] The specific structure of the rotary drive assembly 220 can be designed according to actual needs. For example, the rotary drive assembly 220 includes a rotary drive motor, and the output shaft of the rotary drive motor is driven to connect with the adsorption assembly 230.

[0087] In some optional embodiments, the adsorption assembly 230 includes a rotating arm 231 and a plurality of vacuum suction cups 232, the vacuum suction cups 232 being disposed on the rotating arm 231. Both the multi-axis translation drive assembly 210 and the rotation drive assembly 220 are drivenly connected to the rotating arm 231. The rotating arm 231 can rotate to both sides of the multi-axis translation drive assembly 210 under the drive of the rotation drive assembly 220. The length of the rotating arm 231 can be designed according to actual needs, so that the vacuum suction cups 232 can reach suitable positions. The vacuum suction cups 232 are connected to a negative pressure generating device, and a negative pressure is formed at the vacuum suction cups 232 to adsorb and grasp the phone case. In this embodiment, the rotating arm 231 is connected to the output shaft of the rotation drive motor. Alternatively, the adsorption assembly 230 includes a rotating arm 231 and an electromagnet module. The electromagnet module is mounted on the rotating arm 231. The multi-axis translation drive assembly 210 and the rotation drive assembly 220 are both drivenly connected to the rotating arm 231. The electromagnet module adsorbs and holds the phone case 90. The phone case 90 itself can be magnetic, or magnetic components can be added inside the phone case 90 to facilitate the adsorption of the phone case 90 by the electromagnet module. In this embodiment, the adsorption assembly 230 including the rotating arm 231 and several vacuum suction cups 232 is used as an example for explanation.

[0088] Please refer to Figure 6. In order to facilitate the vacuum suction cup 232 or the electromagnet module to extend into the storage compartment 11 to adsorb the mobile phone case, in some optional embodiments, the storage compartment 11 is provided with a discharge compartment 11 opening and a clearance notch 112 for the rotating arm 231 to pass through. The clearance notch 112 extends in the direction close to the discharge compartment 11 opening and communicates with the discharge compartment 11 opening. Under the drive of the rotation drive component 220, the rotating arm 231 rotates to the vicinity of the discharge compartment 11 opening of the storage compartment 11. Then, the multi-axis translation drive component 210 drives the rotating arm 231 to move towards the storage compartment 11. At this time, the rotating arm 231 will enter the clearance notch 112, so that part of the rotating arm 231 is outside the storage compartment 11 and the other part is inside the storage compartment 11. This facilitates the rotating arm 231 to move towards the mobile phone case in the storage compartment 11 along the clearance notch 112, so that the vacuum suction cup 232 or the electromagnet module can accurately and stably approach the surface of the mobile phone case and realize the gripping of the mobile phone.

[0089] Please refer to Figures 7 and 8. The specific structure of the printing mechanism 50 can be selected according to the actual needs. For example, the printing mechanism 50 includes: a print head assembly 510, a print head drive assembly 520, a position detection assembly 530, and a support beam 41.

[0090] In this embodiment, the support beam 41 is mounted on the frame 10 via the bracket 40. Of course, if the bracket 40 is not provided, the support beam 41 is mounted on the frame 10 or other suitable structure on the frame 10.

[0091] The support beam 41 is equipped with a nozzle guide rail 411.

[0092] The printhead assembly 510 is movably connected to the printhead guide rail 411, and the printhead assembly 510 and the position detection assembly 530 are respectively located on both sides of the support beam 41.

[0093] The printhead drive assembly 520 is driven to connect with the printhead assembly 510, and drives the printhead assembly 510 to move along the printhead guide track 411.

[0094] The printhead assembly 510 and the position detection assembly 530 are respectively positioned on both sides of the support beam 41. The support beam 41 can block the consumables, thereby preventing the consumables ejected from the printhead assembly 510 from adhering to the position detection assembly 530. This effectively prevents the position detection assembly 530 from being contaminated by consumables, which could lead to insensitive sensing or even sensing failure. This also avoids the need for frequent replacement / cleaning of the position detection assembly 530, effectively reducing the number of maintenance operations.

[0095] Please refer to Figures 8 to 10. The specific structure of the position detection component 530 can be selected according to actual needs. For example, the position detection component 530 can be a photoelectric ranging sensor component or an infrared ranging sensor component, etc. In this embodiment, the position detection component 530 includes a grating sensor 531 and a grating strip 532. The grating sensor 531 and the grating strip 532 are inductively coupled. The grating sensor 531 and the grating strip 532 are both arranged on the side of the support beam 41 away from the print head assembly 510. The grating sensor 531 is connected to the print head assembly 510, and the grating strip 532 is arranged on the side of the support beam 41 away from the print head assembly 510. Thanks to the obstruction of the support beam 41, the consumables ejected from the printhead assembly 510 are prevented from adhering to the grating sensor 531 or the grating strip 532, especially preventing contamination of the grating strip 532. This is because the grating strip 532 is relatively long, and due to the distance between the grating strip 532 and the grating sensor 531, the surface of the grating strip 532 needs to be kept clean. Of course, the position detection assembly 530 can also adopt other suitable structures, not limited to the grating sensor 531 and the grating strip 532.

[0096] In some alternative embodiments, two grating holders 412 are provided on the side of the support beam 41 away from the printhead assembly 510. A grating strip 532 is mounted on the two grating holders 412, and a grating sensor 531 is located between the two grating holders 412. The grating holders 412 facilitate the installation of the grating strip 532 and maintain the shape of the grating strip 532.

[0097] In some alternative embodiments, a first limiting portion 413 is formed on the grating holder 412, and two second limiting portions 511 are provided on the print head assembly 510. The two second limiting portions 511 are respectively located on both sides of the grating sensor 531 and are located between the two first limiting portions 413. The first limiting portions 413 are corresponding to the second limiting portions 511 for limiting cooperation. When the grating sensor 531 moves to the limit position, the first limiting portions 413 and the second limiting portions 511 abut against each other to limit the position of the grating sensor 531 relative to the grating strip 532.

[0098] Referring to Figures 11 and 12, in some optional embodiments, the printing mechanism 50 further includes a protective cover 540, which surrounds and forms a printing space 541. The printing space 541 is located on the side of the support beam 41 facing the printhead assembly 510 and below the printhead assembly 510. The protective cover 540 is used to block the consumables ejected from the printhead assembly 510, further effectively preventing consumables from splashing into the environment and bypassing the support beam 41 and adhering to the grating sensor 531 or grating strip 532. The printing position is located within the printing space 541, while the feeding position can be located outside or within the printing space 541.

[0099] In some alternative embodiments, a portion of the protective cover 540 is arranged on the side of the support beam 41 away from the printhead assembly 510, and below the grating sensor 531 and the grating strip 532. Since the printing space 541 is located on the side of the support beam 41 facing the printhead assembly 510 and below it, the splattered consumables mainly diffuse from below the support beam 41. The protective cover 540 protects the area below the grating sensor 531 and the grating strip 532, further preventing consumables from contacting them, in conjunction with the support beam 41.

[0100] In some alternative implementations, the printhead guide rail 411 and the printhead drive assembly 520 are both positioned on the side of the support beam 41 facing the printhead assembly 510, thereby providing ample space for the layout of the grating sensor 531 and the grating strip 532.

[0101] To facilitate the installation of the grating sensor 531 or grating strip 532, in some optional embodiments, the printhead assembly 510 is provided with an extension 512. The extension 512 extends from above the support beam 41 to the side of the support beam 41 away from the printhead assembly 510. The grating sensor 531 or grating strip 532 is mounted on the extension 512, thereby facilitating the connection between the grating sensor 531 or grating strip 532 and the printhead assembly 510. In this embodiment, the grating sensor 531 and the second limiting part 511 are located at the bottom of the extension 512, and the grating strip 532 is located on the side of the support beam 41 away from the printhead assembly 510.

[0102] Furthermore, the extension 512 further prevents consumables from contacting the grating sensor 531 and the grating strip 532. In this embodiment, the extension 512 is located above the grating sensor 531 and the grating strip 532, a portion of the protective cover 540 is located below the grating sensor 531 and the grating strip 532, and the support beam 41 is located on the side of the grating sensor 531 and the grating strip 532 facing the printhead assembly 510. Therefore, consumables can be blocked in three directions, effectively preventing consumables from contacting the grating sensor 531 and the grating strip 532.

[0103] In some alternative embodiments, the extension 512 is connected to a cable chain mechanism 513, which is located on the side of the support beam 41 away from the print head assembly 510. The cable chain mechanism 513 is used to protect pipes and wires such as cables, oil pipes, and air pipes. Since the cable chain mechanism 513 is located on the side of the support beam 41 away from the print head assembly 510, it can also prevent consumables from adhering to the cable chain mechanism 513 and the pipes or wires adhering to the cable chain mechanism 513, which is conducive to the smooth operation of the cable chain mechanism 513 while protecting the pipes and wires.

[0104] The specific structure of the printhead guide rail 411 can be selected according to actual needs. For example, the printhead guide rail 411 can be a convex rail, and the printhead assembly 510 can slide with the convex rail through a slider. This example is not limited to this one.

[0105] The specific structure of the printhead drive assembly 520 can be selected according to actual needs. For example, the printhead drive assembly 520 can adopt a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc. In this embodiment, the printhead drive assembly 520 adopts a belt translation drive assembly. The belt structure is set on the side of the support beam 41 facing the printhead assembly 510, and the belt drive motor is set on the side of the support beam 41 away from the printhead assembly 510 and is drivenly connected to the belt structure. The belt structure is drive-connected to the printhead assembly 510.

[0106] Please refer to Figures 13 and 14. The specific structure of the phone case shaping fixture 60 can be selected according to the actual needs. For example, the phone case shaping fixture 60 includes: a phone case shaping base 610 and a positioning component 620.

[0107] The positioning component 620 is disposed on the phone case shaping base 610 and is used to push the phone case 90 to the preset shaping position 611 on the phone case shaping base 610.

[0108] The positioning component 620 includes a positioning drive component 621 and four positioning elements 622. The four positioning elements 622 are disposed on the phone case shaping base 610 and are located on the four sides of the shaping position 611 respectively.

[0109] The positioning drive component 621 drives the positioning members 622 located on both sides of the shaping position 611 to move relative to the phone case shaping base 610; alternatively, the positioning drive component 621 drives the positioning members 622 located on three sides of the shaping position 611 to move relative to the phone case shaping base 610; or, the positioning drive component 621 drives all four positioning members 622 to move relative to the phone case shaping base 610, so that the corresponding positioning members 622 move closer to or further away from the shaping position 611. When positioning is completed, the four positioning members 622 are positioned on the sides of the shaping position 611, thereby confining the phone case 90 within the shaping position 611. The positioning drive component 621 can both drive the phone case shaping base 610 to move so that the positioning member 622 moves closer to or away from the shaping base, and drive the positioning member 622 to move towards the shaping base so that the positioning member 622 moves closer to or away from the shaping position 611. In this embodiment, the positioning drive component 621 and the positioning member 622 are driven together as an example. The positioning member 622 driven by the positioning drive component 621 is a movable positioning member 6221. In some embodiments, the structures of the fixed positioning member 6222 and the movable positioning member 6221 may be different to meet structural design requirements.

[0110] Please refer to Figure 15. When the first positioning method is adopted: the positioning drive component 621 drives the positioning members 622 located on both sides adjacent to the shaping position 611 to move relative to the phone case shaping base 610. At this time, two of the positioning members 622 are fixed positioning members 6222. The fixed positioning members 6222 are fixed in position relative to the phone case shaping base 610. The fixed positioning members 6222 can be fixed on the phone case shaping base 610. The fixed positioning members 6222 can be arranged on the side edge of the shaping position 611 to facilitate the positioning of the phone case 90. The other two positioning members 622 are movable positioning members 6221. After the phone case 90 is placed on the phone case shaping base 610, the positioning drive component 621 can drive the movable positioning member 6221 to move, so that the movable positioning member 6221 moves towards the shaping position 611 until the movable positioning member 6221 pushes the phone case 90 towards the shaping position 611, and so that the four sides of the phone case 90 abut against the two fixed positioning members 6222 and the two movable positioning members 6221 respectively. In this embodiment, the positioning drive component 621 is drivenly connected to the movable positioning member 6221.

[0111] Please refer to Figure 16. When the second positioning method is adopted: the positioning drive component 621 drives the positioning members 622 on the three sides adjacent to the shaping position 611 to move relative to the phone case shaping base 610. At this time, one of the positioning members 622 is a fixed positioning member 6222. The fixed positioning member 6222 is fixed in position relative to the phone case shaping base 610. The fixed positioning member 6222 can be fixed on the phone case shaping base 610. The fixed positioning member 6222 can be arranged on the side edge of the shaping position 611 to facilitate the positioning of the phone case 90. The other three positioning members 622 are movable positioning members 6221. After the phone case 90 is placed on the phone case shaping base 610, the positioning drive component 621 drives the movable positioning component 6221 to move, so that the movable positioning component 6221 moves toward the shaping position 611 until the movable positioning component 6221 pushes the phone case 90 toward the shaping position 611, and so that the four sides of the phone case 90 respectively abut against one fixed positioning component 6222 and three movable positioning components 6221, thereby achieving the positioning of the phone case 90.

[0112] Please refer to Figure 17. When using the third positioning method: the positioning drive component 621 drives the positioning members 622 located on the four sides adjacent to the shaping position 611 to move relative to the phone case shaping base 610. All four positioning members 622 are movable positioning members 6221. After the phone case 90 is placed on the phone case shaping base 610, the positioning drive component 621 drives the four movable positioning members 6221 to move, so that the positioning members 622 move towards the shaping position 611 until the movable positioning members 6221 push the phone case 90 towards the shaping position 611, and so that the four sides of the phone case 90 respectively abut against the four movable positioning members 6221.

[0113] In some optional embodiments, the sides of any two adjacent positioning members 622 used for positioning the phone case 90 are perpendicular to each other. If the phone case 90 is tilted relative to the side of the positioning member 622 used for positioning the phone case 90, after the side of the positioning member 622 abuts against the phone case 90, when the positioning member 622 pushes the phone case 90 to the shaping position 611, it will drive the phone case 90 to gradually align with the side corresponding to the shaping position 611, so that the phone case 90 is accurately positioned.

[0114] In this embodiment, the positioning drive component 621 is driven to connect with the positioning element 622. The positioning element 622 connected to the positioning drive component 621 is a movable positioning element 6221. The movable positioning element 6221 is movably connected to the phone case shaping base 610 and is relatively movable to the phone case shaping base 610.

[0115] Referring to Figures 14 and 18, in some optional embodiments, the positioning drive assembly 621 further includes multiple positioning power modules 6211. Each positioning power module 6211 is connected to and drives the movable positioning member 6221, causing it to move closer to or further away from the shaping position 611. This allows for precise control of the movable positioning member 6221. Of course, in other embodiments, depending on the number of movable positioning elements 6221, for example, when there are two movable positioning elements 6221, the positioning drive component 621 may include only one positioning power module 6211, which can drive both movable positioning elements 6221 to move simultaneously, thereby reducing structural complexity; or, when there are three movable positioning elements 6221, the positioning drive component 621 may include two positioning power modules 6211, one of which is driven connected to one movable positioning element 6221, and the other is driven connected to both movable positioning elements 6221; or, when there are four movable positioning elements 6221, the positioning drive component 621 may include two positioning power modules 6211, which are driven connected to both movable positioning elements 6221.

[0116] Please refer to Figure 18. The specific structure of the positioning power module 6211 can be selected according to actual needs. For example, in some optional embodiments, the positioning power module 6211 includes a positioning drive motor 62111 and a positioning transmission gear 62112. The positioning drive motor 62111 and the positioning transmission gear 62112 are drivenly connected. The movable positioning member 6221 is provided with a rack portion 62211. The positioning transmission gear 62112 meshes with the rack portion 62211. The positioning drive motor 62111 drives the positioning transmission gear 62112 to rotate, and the positioning transmission gear 62112 drives the movable positioning member 6221 to move through the rack portion 62211. Of course, the positioning power module 6211 can also adopt a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc., and is not limited to this example.

[0117] In some alternative implementations, the moving direction of the active positioning member 6221 is perpendicular to the side of the phone case 90 it is used to position, and the moving direction of the second positioning member 622 is perpendicular to the side of the phone case 90 it is used to position, thereby facilitating the matching of the side of the phone case 90 and making the phone case 90 stably positioned.

[0118] To facilitate the installation of the positioning drive component 621 and prevent it from being affected by dust and impurities in the environment, in some optional embodiments, the phone case shaping base 610 is also provided with a mounting cavity 612 and multiple guide slots 613. The multiple guide slots 613 are arranged around the shaping position 611 and communicate with the mounting cavity 612. The positioning drive component 621 is disposed in the mounting cavity 612. The movable positioning member 6221 slides in cooperation with the guide slots 613. Part of the movable positioning member 6221 extends into the mounting cavity 612 and then drives and connects with the positioning drive component 621. The guide slots 613 can guide the movable positioning member 6221 to slide stably, improving the movement stability of the movable positioning member 6221.

[0119] In some optional embodiments, a baffle plate 62212 is provided on the movable positioning member 6221. The baffle plate 62212 is located within the mounting cavity 612 and closes at least a portion of the guide groove 613. The baffle plate 62212 moves with the movable positioning member 6221. When the phone case 90 is not being positioned, the baffle plate 62212 can prevent dust and other impurities in the environment from entering the mounting cavity 612 through the guide groove 613, thereby improving the protection of the positioning drive assembly 621. In this embodiment, the rack portion 62211 is provided on the baffle plate 62212.

[0120] In some optional embodiments, a phone case detection component 614 is provided on the phone case shaping base 610. The phone case detection component 614 faces the shaping position 611 and is signal-connected to the positioning drive component 621. The phone case detection component 614 is used to detect whether the phone case 90 is placed at the shaping position 611. When the phone case detection component 614 detects the phone case 90, it sends a positioning signal to the positioning drive component 621, and then the positioning component 620 positions the phone case 90. The phone case detection component 614 can be a photoelectric sensor, infrared sensor, ultrasonic sensor, proximity switch, etc. The detection methods such as photoelectric sensors, infrared sensors, ultrasonic sensors, and proximity switches are technologies known to those skilled in the art and will not be described in detail here.

[0121] Referring to Figures 19 and 20, in some alternative embodiments, the height adjustment mechanism 70 includes:

[0122] The lifting drive assembly 710 is connected to the phone case shaping base 610 of the phone case shaping fixture 60 and is used to drive the phone case shaping base 610 of the phone case shaping fixture 60 to lift.

[0123] A height detection component 720 is used to detect whether the phone case 90 has reached a preset height. The height detection component 720 is arranged on one side of the phone case shaping fixture 60 and is signal-connected to the lifting drive component 710. The height of the phone case shaping base 610 is adjusted by the lifting drive component 710, thereby adjusting the height of the phone case 90. The height detection component 720 determines whether the phone case 90 has reached the preset height. After the lifting drive component 710 drives the phone case shaping base 610 to rise and fall so that the phone case 90 reaches the preset height, the printing mechanism can print on the phone case 90. The height of the phone case shaping base 610 is adjusted by the lifting drive component 710 to accommodate the thickness difference of different phone cases 90, avoiding the impact of the thickness difference on the printing effect. The overall structure is relatively simple and the cost is low.

[0124] It should be noted that when the phone case 90 is at the preset height, the distance between the top surface of the phone case 90 and the printing mechanism 50 is sufficient for the printing mechanism 50 to print effectively. The top surface of the phone case 90 will not be too far away from or too close to the printing mechanism 50, thus affecting the printing effect. The printing mechanism 50 and the phone case 90 will not collide.

[0125] In some alternative embodiments, the mobile phone case printing device 30 also includes a conveying mechanism 80, which is mounted on the bracket 40 and drivenly connected to the height adjustment mechanism 70, driving the height adjustment mechanism 70 to move relative to the printing mechanism 50 to the feeding position and the printing position.

[0126] The height adjustment mechanism 70 is moved to a loading position away from the printing mechanism 50 by the conveying mechanism 80, making it easier to place the phone case 90 on the phone shaping fixture and preventing the printing mechanism 50 from obstructing the placement process. After the phone case 90 is placed, the conveying mechanism 80 transports it to the printing position below the printing mechanism 50 for printing. In this embodiment, the printing position and the loading position are arranged sequentially near the phone case 90 storage and handling mechanism 20, which facilitates the quick placement of the phone case 90 onto the phone case shaping fixture 60 by the phone case storage and handling mechanism 20, shortening the movement path of the phone case 90.

[0127] During the process of the conveying mechanism 80 driving the height adjustment mechanism 70 to move from the loading position to the printing position, the height of the phone case 90 can be adjusted. If the height detection component 720 detects that the phone case 90 is present at the preset height, the lifting drive component 710 drives the phone case shaping fixture 60 to slowly descend until the height detection component 720 just fails to detect the phone case 90 at the preset height. At this point, the phone case shaping fixture 60 immediately stops descending, so that the top surface of the phone case 90 is exactly at the preset height. If the height detection component 720 does not detect that the phone case 90 is present at the preset height, the lifting drive component 710 drives the phone case shaping fixture 60 to rise until the height detection component 720 detects that the phone case 90 is present at the preset height. Then, the lifting drive component 710 drives the phone case shaping fixture 60 to slowly descend until the height detection component 720 just fails to detect the phone case 90 at the preset height. At this point, the phone case shaping fixture 60 immediately stops descending, so that the top surface of the phone case 90 is exactly at the preset height.

[0128] The specific method by which the height detection component 720 determines whether the height of the phone case 90 reaches the preset height can be selected according to actual needs. For example, in some optional embodiments, the height detection component 720 includes a light emitter 721 and a light receiver 722, which are respectively disposed on both sides of the phone case shaping fixture 60. The light emitter 721 can be of different types, such as an infrared light emitter 721, a visible light emitter 721, etc. In this embodiment, the light emitter 721 is used as a laser emitter and the light receiver 722 is used as a laser receiver. The laser emitter and laser receiver are arranged at a preset height, between the loading position and the printing position, to detect in real time whether a mobile phone case 90 exists at the preset height. The laser receiver determines whether a mobile phone case 90 exists by detecting the laser emitted by the laser emitter, and then determines whether the mobile phone case 90 exceeds the preset height. If the laser receiver does not receive the laser emitted by the laser emitter, it means that a mobile phone case 90 has been detected, indicating that the height of the mobile phone case 90 exceeds the preset height. The laser emitter sends a signal to the lifting drive assembly 710, which drives the mobile phone case shaping fixture 60 to slowly descend until the laser receiver receives the laser emitted by the laser emitter. Component 710 immediately stops descending. At this point, the phone case 90 is not detected, and the phone case 90 is at the preset height. If the laser emitter receives a laser beam, it means the phone case 90 is not detected, indicating that its height is below the preset height. The laser emitter sends a signal to the lifting drive component 710, which drives the phone case shaping fixture 60 to rise until the laser receiver no longer receives a laser beam. At this point, the phone case 90's height exceeds the preset height. Then, the laser emitter sends a signal to the lifting drive component 710, which drives the phone case shaping fixture 60 to slowly descend until the laser emitter just receives a laser beam, meaning the phone case 90 is no longer detected. At this point, the lifting drive component 710 immediately stops descending, and the phone case 90 is at the preset height. The conveying mechanism 80 and the height adjustment mechanism 70 can operate simultaneously. That is, while the conveying mechanism 80 moves the height adjustment mechanism 70 from the loading position to the printing position, the height adjustment mechanism 70 simultaneously adjusts the height of the phone case 90, thereby improving work efficiency.

[0129] Alternatively, in some other optional embodiments, the height detection component 720 includes a distance sensor positioned above the phone shaping base and facing the top of the phone shaping base. The distance sensor faces the phone case 90 on the phone case shaping fixture 60. By detecting the distance between the phone case 90 and the distance sensor, it is determined whether the phone case 90 has reached a preset height. The distance sensor can employ different types of detection methods, such as a proximity switch, an infrared distance sensor, etc., and is not limited to this example.

[0130] Alternatively, in some other optional embodiments, the height detection component 720 includes a thickness sensor and a distance sensor disposed on one side of the phone case shaping fixture 60, which can detect the thickness of the phone case 90. Since the area to be printed on the phone case 90 is usually located at the top of the phone case 90, the height required to be raised by subtracting the thickness of the phone case 90 from the preset height can be obtained, thereby raising the phone case shaping fixture 60 until the phone case 90 reaches the preset height.

[0131] Alternatively, in some other optional implementations, the height detection component 720 includes a contact sensor that determines whether the phone case has reached a preset height by judging whether the phone case just touches the contact sensor located at a preset height.

[0132] Alternatively, in some other optional embodiments, the height detection component 720 includes a phone case height calculation unit that is signal-connected to the lifting drive component 710. The height at which the lifting drive component 710 drives the phone case shaping base 610 to rise and fall, as well as the current height of the phone case shaping base 610, can be calculated in real time. For example, when the lifting drive component 710 uses a motor as its power source, the current height of the phone case shaping base 610 can be determined in real time through the motor's operating data. Since the dimensions (length, width, and thickness) of the phone case 90 can be pre-acquired and stored, after the user selects the corresponding model of phone case 90, the phone case storage and handling mechanism moves the phone case 90. The phone case height calculation unit receives the thickness information of the phone case 90 selected by the user and, based on the thickness of the phone case 90 plus the current height of the phone case shaping base 610, can measure the current height of the phone case 90 in real time. The lifting drive component 710 adjusts the height of the phone case shaping base 610 based on the current height of the phone case 90, so that the phone case 90 reaches the preset height. The phone case height calculation unit can use components such as processors and arithmetic circuits to perform calculations.

[0133] Please refer to Figures 21 and 22. The specific structure of the lifting drive assembly 710 can be selected according to actual needs. For example, in some optional embodiments, the lifting drive assembly 710 includes a base 711, a lifting power motor 712, a lifting transmission mechanism 713, and multiple lifting screws 714. The multiple lifting screws 714 are mounted on the base 711 and are driven and connected to the phone case shaping base 610. The lifting power motor 712 is signal-connected to the height detection component 720. The lifting power motor 712 is driven and connected to the multiple lifting screws 714 through the lifting transmission mechanism 713. The rotation of the lifting screws 714 drives the phone case shaping base 610 to rise and fall. The multiple lifting screws 714 can stably drive the phone case shaping base 610 to rise and fall and maintain the angle of the phone case shaping base 610 relative to the horizontal plane. In this embodiment, there are four lifting screws 714, located near the four corners of the phone case shaping base 610, which helps to maintain the angle of the phone case shaping base 610 relative to the horizontal plane. Of course, the lifting drive assembly 710 can also be a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc., and is not limited to this example.

[0134] Please refer to the figure. The specific structure of the lifting transmission mechanism 713 can be selected according to actual needs. For example, in some optional embodiments, the lifting transmission mechanism 713 includes a synchronous belt 7131, a driving synchronous pulley 7132, and multiple transmission synchronous pulleys 7133. The driving synchronous pulley 7132 is connected to the output end of the lifting power motor 712, and the transmission synchronous pulleys 7133 are connected to the lifting screw 714. The synchronous belt 7131 meshes with the driving synchronous pulley 7132 and the transmission synchronous pulleys 7133. The lifting power motor 712 drives the driving synchronous pulley 7132 to rotate, the driving synchronous pulley 7132 drives the synchronous belt 7131 to move, the synchronous belt 7131 drives the transmission synchronous pulleys 7133 to rotate, and the rotation of the synchronous pulleys drives the lifting screw 714 to rotate, thereby realizing the transmission.

[0135] In some alternative embodiments, a mounting part 7111 is provided on the base 711, the mounting part 7111 extends from one side of the base 711, and the lifting motor 712 is provided on the mounting part 7111. By arranging the lifting motor 712 on one side of the base 711, the thickness and length and width of the base 711 can be reduced, and the structure can be simplified.

[0136] Please refer to Figures 1 and 2. In some optional embodiments, the base 711 is provided with an assembly cavity 7112. The assembly cavity 7112 is provided with a plurality of first mounting holes 7113 located at the top of the assembly cavity 7112 and a plurality of second mounting holes 7114 located at the bottom of the assembly cavity 7112. The driving synchronous wheel 7132 and the transmission synchronous wheel 7133 are rotatably disposed in the assembly cavity 7112. The top ends of the driving synchronous wheel 7132 and the transmission synchronous wheel 7133 are connected to the first mounting holes 7113 respectively, and the bottom ends of the driving synchronous wheel 7132 and the transmission synchronous wheel 7133 are connected to the second mounting holes 7114 respectively. The assembly cavity 7112 is beneficial for providing a certain degree of protection for the driving synchronous wheel 7132 and the transmission synchronous wheel 7133, and is also beneficial for the stable assembly of the driving synchronous wheel 7132 and the transmission synchronous wheel 7133. The assembly cavity 7112 has an assembly opening 7115 on the side facing the mounting part 7111. The lifting power motor 712 is mounted on the mounting part 7111. One part of the synchronous belt 7131 is arranged inside the assembly cavity 7112 and meshes with the transmission synchronous pulley 7133. The other part of the synchronous belt 7131 extends from the assembly opening 7115 to the outside of the assembly cavity 7112 and meshes with the drive synchronous pulley 7132. The lifting power motor 712 is located outside the assembly cavity 7112. The size of the assembly cavity 7112 does not need to be designed to be too large.

[0137] In some optional embodiments, the lifting transmission mechanism 713 further includes a first guide synchronous wheel 7134 and a second guide synchronous wheel 7135. The first guide synchronous wheel 7134 and the second guide synchronous wheel 7135 are rotatably disposed in the assembly cavity 7112 and located on one side of the assembly opening 7115. The top ends of the first guide synchronous wheel 7134 and the second guide synchronous wheel 7135 are connected to the first mounting hole 7113, and the bottom ends of the first guide synchronous wheel 7134 and the second guide synchronous wheel 7135 are connected to the second mounting hole 7114, thereby improving the installation stability of the first guide synchronous wheel 7134 and the second guide synchronous wheel 7135. The synchronous belt 7131 located in the assembly cavity 7112 engages sequentially with the first guide synchronous pulley 7134, multiple transmission synchronous pulleys 7133, and the second guide synchronous pulley 7135. In order to maintain the tension of the synchronous belt 7131 without friction with the assembly opening 7115, the first guide synchronous pulley 7134 and the second guide synchronous pulley 7135 guide the synchronous belt 7131 to turn near the assembly opening 7115, so that the synchronous belt 7131 can pass smoothly through the assembly opening 7115. This allows the size of the assembly opening 7115 to be designed to be relatively small, improving the protective performance of the assembly cavity 7112. The synchronous belt 7131 passes sequentially through the drive synchronous pulley 7132, the first guide synchronous pulley 7134, multiple transmission synchronous pulleys 7133, and the second guide synchronous pulley 7135, and then returns to the drive synchronous pulley 7132.

[0138] Bearings can be installed in the first mounting hole 7113 and the second mounting hole 7114, and the lifting screw 714 passes through the bearings, thereby improving the stability of the rotation of the lifting screw 714.

[0139] The specific structure of the conveying mechanism 80 can be selected according to actual needs. For example, the conveying mechanism 80 can adopt a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc. In this embodiment, the conveying mechanism 80 adopts a synchronous belt 7131 translation drive assembly.
