Description

Technical Field

[0001] The invention relates to the technical field of mobile phone cases, and in particular to an unmanned vending machine for customizing mobile phone cases. Background Art

[0002] With the development of science and technology, smart phones are widely used. When people buy smart phones, they will put a mobile phone case on the outside of the smart phone to protect the smart phone and decorate the phone, making the mobile phone case more personalized. In the mobile phone case vending machine, a printing device is usually set to print the mobile phone case, so that users can customize the pattern of the mobile phone case.

[0003] Since there are many types of mobile phones used by users and different mobile phones have different thicknesses, the corresponding thickness of the mobile phone case is also different. After the robot arm of the vending machine puts the mobile phone case into the positioning structure of the printing device, it does not adjust the height of the mobile phone case. As a result, during the printing process, some overly thick mobile phone cases are close to the printing nozzle, which will affect the printing effect and may even collide with the printing nozzle.

[0067] See also Figure 1 and Figure 2 An embodiment of the present invention provides an unmanned mobile phone case customization vending machine, including: a frame 10, a mobile phone case storage and transportation mechanism 20 and a mobile phone case printing device 30.

[0068] A plurality of cargo compartments 11 are disposed on the frame 10 .

[0069] The mobile phone case printing device 30 is arranged on one side of the mobile phone case storage and transportation mechanism 20 , and the mobile phone case storage and transportation mechanism 20 transports the mobile phone cases between the warehouse 11 and the mobile phone case printing device 30 .

[0070] In order to facilitate the installation of the mobile phone shell printing device 30, a bracket 40 is also provided on the frame 10, and the bracket 40 is detachably connected to the frame 10. The mobile phone shell printing device 30 is arranged on the bracket 40, so that the mobile phone shell printing device 30 and the bracket 40 form a modular design, which is convenient for production and assembly and subsequent disassembly, maintenance and replacement. Among them, the mobile phone shell printing device 30 includes a printing mechanism 50, a mobile phone shell shaping jig 60, a height adjustment mechanism 70 and a conveying mechanism 80.

[0071] The printing mechanism 50 is disposed on the bracket 40 and is used for printing on the mobile phone case.

[0072] The mobile phone case shaping jig 60 is arranged below the printing mechanism 50 and is used to position the mobile phone case.

[0073] The height adjustment mechanism 70 is drivingly connected to the mobile phone case shaping jig 60 , and the height adjustment mechanism 70 drives the mobile phone case shaping jig 60 to move up and down so that the mobile phone case on the mobile phone case shaping jig 60 is at a preset height relative to the printing mechanism 50 .

[0074] The following is an explanation of the operating principle of the mobile phone case customized vending machine: after the mobile phone case storage and handling mechanism 20 takes the mobile phone case out of the warehouse 11, it places the mobile phone case on the mobile phone case shaping jig 60, the mobile phone case shaping jig 60 positions the mobile phone case, and then the height adjustment mechanism 70 adjusts the height of the mobile phone case shaping jig 60 so that the mobile phone case is at a preset height suitable for the printing mechanism 50 to print. After printing is completed, the mobile phone case storage and handling mechanism 20 removes the mobile phone case from the mobile phone case shaping jig 60, and then transports the mobile phone case to a suitable position so that the user can take the printed mobile phone case.

[0075] See also Figure 3 and Figure 4 In some optional embodiments, the mobile phone shell storage and handling mechanism 20 includes a multi-axis translation drive component 210, a rotation drive component 220 and an adsorption component 230;

[0076] The multi-axis translation driving assembly 210 is drivingly connected to the adsorption assembly 230, and is used to drive the adsorption assembly 230 to translate;

[0077] The rotation driving assembly 220 is drivingly connected to the adsorption assembly 230, and is used to drive the adsorption assembly 230 to rotate to both sides of the multi-axis translation driving assembly 210;

[0078] The adsorption component 230 is used to grab the mobile phone case;

[0079] Multiple cargo bins 11 are arranged on both sides of the multi-axis translation drive assembly 210, wherein some of the cargo bins 11 and the mobile phone case printing device 30 are located on the same side of the multi-axis translation drive assembly 210, and other cargo bins 11 and the mobile phone case printing device 30 are located on both sides of the multi-axis translation drive assembly 210 respectively.

[0080] The multi-axis translation module can drive the adsorption component 230 to move to one side of any warehouse 11, and then the rotation drive component 220 drives the adsorption component 230 to rotate toward the warehouse 11, so that the adsorption component 230 moves to the exit of the warehouse 11. The adsorption component 230 can enter the warehouse 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 shell in the warehouse 11 to grasp the mobile phone shell, and then the adsorption component 230 correspondingly detaches from the warehouse 11 under the drive of the adsorption component 230 or the multi-axis translation module. The mobile phone shell can be stably adsorbed by the adsorption component 230 to achieve stable grasping. The multi-axis translation module and the rotation drive component 220 can drive the adsorption component 230 to move flexibly, which is convenient for picking up goods, and a large number of warehouses 11 can be arranged.

[0081] 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 hold 11 can be arranged on both sides of the multi-axis translation drive component 210, thereby increasing the layout space of the cargo hold 11, increasing the number of mobile phone cases that can be stored, and making the structure more compact.

[0082] See also Figure 5 In some optional embodiments, a discharge bin 12 is provided on the frame 10, and the mobile phone shell printing device 30 of the discharge bin 12 is arranged on the same side of the mobile phone shell storage and handling mechanism 20, and a feed bin 121 is provided on the top of the discharge bin 12; the mobile phone shell storage and handling mechanism 20 transports the mobile phone shell between the cargo bin 11, the printing mechanism 50 and the discharge bin 12. Since the space occupied by the mobile phone shell printing device 30 and the discharge bin 12 is not large, by adding the cargo bin 11 on both sides of the multi-axis translation drive assembly 210, the layout space of the cargo bin 11 can be increased, the number of mobile phone shells stored is increased, and the structure is made more compact. After printing is completed, the mobile phone shell storage and handling mechanism 20 removes the mobile phone shell from the mobile phone shell shaping jig 60, and then transports the mobile phone shell to the top of the discharge bin 12, and then puts the mobile phone shell down, so that the mobile phone shell falls into the discharge bin 12 from the feed bin 121, and the user prints the completed mobile phone shell from the discharge bin 12. In this embodiment, a material taking port for the user to insert his hand is provided on one side of the material discharging bin 12 .

[0083] In some optional embodiments, a slanted guide plate 122 is provided on one side of the feed port 121 facing the multi-axis translation drive assembly 210, and the slanted guide plate 122 gradually tilts downward in a direction away from the multi-axis translation drive assembly 210. The adsorption assembly 230 moves to the top of the slanted guide plate 122 under the drive of the multi-axis translation drive assembly 210 and the rotation drive assembly 220, and then the adsorption assembly 230 puts down the grabbed mobile phone shell, and the mobile phone shell falls on the slanted guide plate 122, and then is guided by the slanted guide plate 122 through the feed port 121, and then enters the discharge bin 12, and the user can take out the mobile phone shell from the discharge bin 12. The slanted guide plate 122 facilitates the mobile phone shell to tilt away from the multi-axis translation drive assembly 210 and then enter the discharge bin 12, so that the other structures of the discharge bin 1214 except the slanted guide plate 122 can be arranged at a position farther away from the multi-axis translation drive assembly 210 to avoid interference with the multi-axis translation drive assembly 210.

[0084] The specific structure of the multi-axis translation drive assembly 210 can be appropriately designed 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 connected to the adsorption assembly 230 for driving the adsorption assembly 230 to move in the first direction. The second translation drive module 212 is connected to the adsorption assembly 230 for driving the adsorption assembly 230 to move in the second direction. The first direction and the second direction are perpendicular to each other. A plurality of warehouses 11 are arranged on at least one side of the first translation drive module 211. In this embodiment, the warehouses 11 are arranged in a matrix in the first direction and the second direction, so that the multi-axis translation drive assembly 210 can accurately drive the adsorption assembly 230 to move to one side of the warehouse 11. In this embodiment, the warehouses 11, the mobile phone shell printing device 30 and the discharge warehouse 12 are distributed on both sides of the first translation drive module 211, which effectively utilizes the space on both sides of the first translation drive module 211.

[0085] In some optional embodiments, the multi-axis translation drive assembly 210 further includes a third translation drive module, which is drivingly connected to the adsorption assembly 230 and is used to drive the adsorption assembly 230 to move in a third direction, and the first direction, the second direction and the third direction are perpendicular to each other. When the positions on both sides of the first translation drive module 211 for arranging the cargo warehouse 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 cargo warehouse 11, the printing station or the discharge station. In this embodiment, the first direction is the front-to-back direction of the frame 10, the second direction is the up-and-down direction of the frame 10, and the third direction is the left-right direction of the frame 10, without limiting this example.

[0086] 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 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 first translation drive module 211 and the second translation drive module 212 both adopt belt translation drive components. The frame 10 is provided with a first guide rail extending along the first direction, a first support seat slidably matched with the first guide rail, a second guide rail extending along the second direction and a second support seat slidably matched with the second guide rail. The first translation drive module 211 is arranged on the frame 10, and the belt of the first translation drive module 211 is driven and connected to the first support seat. The second translation drive module 212 is arranged on the first support seat, and the belt of the second translation drive module 212 is driven and connected to the second support seat. The rotation drive assembly 220 is arranged on the second support seat and then driven and connected to the adsorption assembly 230. The first translation drive module 211 drives the first support seat to move to drive the adsorption assembly 230 to move in the first direction, and the second translation drive module 212 drives the second support seat to move to drive the adsorption assembly 230 to move in the second direction.

[0087] The specific structure of the rotation driving assembly 220 can be designed according to actual needs. For example, the rotation driving assembly 220 includes a rotation driving motor, and the output shaft of the rotation driving motor is drivingly connected to the adsorption assembly 230.

[0088] 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 are arranged on the rotating arm 231, and the multi-axis translation drive assembly 210 and the rotation drive assembly 220 are both driven and connected to the rotating arm 231. The rotating arm 231 can be rotated to both sides of the multi-axis translation drive assembly 210 driven by the rotation drive assembly 220, and the length of the rotating arm 231 can be designed according to actual needs so that the vacuum suction cup 232 can reach a suitable position. The vacuum suction cup 232 is connected to the negative pressure generating device, and negative pressure is formed at the vacuum suction cup 232 to adsorb and grasp the mobile phone case. In this embodiment, the rotating arm 231 is connected to the output shaft of the rotation drive motor. Alternatively, the adsorption component 230 includes a rotating arm 231 and an electromagnet module, the electromagnet module is arranged on the rotating arm 231, the multi-axis translation drive component 210 and the rotation drive component 220 are both connected to the rotating arm 231, and the electromagnet module is used to adsorb and clamp the mobile phone case 90. The mobile phone case 90 itself can be magnetic, or a magnetic part can be added inside the mobile phone case 90, so as to facilitate the electromagnet module to adsorb the mobile phone case 90. In this embodiment, the adsorption component 230 including the rotating arm 231 and a plurality of vacuum suction cups 232 is used as an example for description.

[0089] See also Figure 6 In order to facilitate the vacuum suction cup 232 or the electromagnet module to extend into the cargo warehouse 11 to absorb the mobile phone case, in some optional embodiments, the cargo warehouse 11 is provided with an outlet port of the cargo warehouse 11 and an avoidance gap 112 for the rotating arm 231 to pass through. The avoidance gap 112 extends in the direction close to the outlet port of the cargo warehouse 11 and is connected to the outlet port of the cargo warehouse 11. When the rotating arm 231 is driven by the rotation drive assembly 220 to rotate to the vicinity of the outlet port of the cargo warehouse 11, the multi-axis translation drive assembly 210 drives the rotating arm 231 to move toward the cargo warehouse 11. At this time, the rotating arm 231 will enter the avoidance gap 112, so that a part of the rotating arm 231 is located outside the cargo warehouse 11, and the other part is located inside the cargo warehouse 11, so that the rotating arm 231 is driven to move toward the mobile phone case in the cargo warehouse 11 along the avoidance gap 112, so that the vacuum suction cup 232 or the electromagnet module accurately and stably approaches the surface of the mobile phone case, thereby realizing the grabbing of the mobile phone.

[0090] See also Figure 7 and Figure 8 The specific structure of the printing mechanism 50 can be appropriately designed according to actual needs. For example, the printing mechanism 50 includes: a print head assembly 510, a print head driving assembly 520, a position detection assembly 530 and a support beam 41.

[0091] In this embodiment, the support beam 41 is installed on the frame 10 through the bracket 40. Of course, when the bracket 40 is not arranged, the support beam 41 is installed on the frame 10 or other suitable structures on the frame 10.

[0092] A nozzle guide rail 411 is provided on the support beam 41 .

[0093] The print head assembly 510 is movably connected to the nozzle guide track 411 , and the print head assembly 510 and the position detection assembly 530 are respectively arranged on both sides of the support beam 41 .

[0094] The nozzle driving assembly 520 is drivingly connected to the printing nozzle assembly 510 , and drives the printing nozzle assembly 510 to move along the nozzle guiding track 411 .

[0095] The print head assembly 510 and the position detection assembly 530 are respectively arranged on both sides of the support beam 41. The support beam 41 can block the consumables, thereby preventing the consumables sprayed by the print head assembly 510 from adhering to the position detection assembly 530, thereby effectively preventing the position detection assembly 530 from being contaminated by the consumables and causing insensitive sensing or even sensing failure, avoiding the need for frequent replacement / cleaning of the position detection assembly 530, and effectively reducing the number of maintenance times.

[0096] See also Figures 8 to 10 The specific structure of the position detection component 530 can be appropriately designed 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 the present embodiment, the position detection component 530 includes a grating sensor 531 and a grating bar 532, and the grating sensor 531 and the grating bar 532 cooperate with each other in induction. The grating sensor 531 and the grating bar 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 bar 532 is arranged on the side of the support beam 41 away from the print head assembly 510. Benefiting from the blocking of the support beam 41, the consumables ejected from the print head assembly 510 are prevented from adhering to the grating sensor 531 or the grating strip 532, and in particular, the grating strip 532 is prevented from being contaminated by the consumables, because the grating strip 532 is relatively long, and the surface of the grating strip 532 needs to be kept smooth due to the sensing distance between the grating strip 532 and the grating sensor 531. Of course, the position detection assembly 530 may also adopt other suitable structures, not limited to the grating sensor 531 and the grating strip 532.

[0097] In some optional embodiments, two grating fixing frames 412 are provided on one side of the support beam 41 away from the print head assembly 510, the grating strip 532 is mounted on the two grating fixing frames 412, and the grating sensor 531 is located between the two grating fixing frames 412. The grating fixing frame 412 facilitates the installation of the grating strip 532 and maintains the shape of the grating strip 532.

[0098] In some optional embodiments, a first limiting portion 413 is formed on the grating fixing frame 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 the two second limiting portions 511 are located between the two first limiting portions 413. The first limiting portion 413 corresponds to the second limiting portion 511 for limiting cooperation. When the grating sensor 531 moves to the extreme position, the first limiting portion 413 and the second limiting portion 511 abut against each other to limit the position of the grating sensor 531 relative to the grating bar 532.

[0099] See also Fig.11 and Fig.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 print head assembly 510 and is located below the print head assembly 510. The protective cover 540 is used to block the consumables sprayed by the print head assembly 510, further effectively preventing the consumables from splashing in the environment and bypassing the support beam 41 and adhering to the grating sensor 531 or the grating bar 532. The printing position is located in the printing space 541, and the loading position can be located outside the printing space 541 or in the printing space 541.

[0100] In some optional embodiments, part of the protective cover 540 is arranged on the side of the support beam 41 away from the print head assembly 510, and is located 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 print head assembly 510 and is located below the print head assembly 510, the splashed consumables mainly diffuse from the bottom of the support beam 41. The protective cover 540 protects the bottom of the grating sensor 531 and the grating strip 532, and can cooperate with the support beam 41 to further prevent the consumables from contacting the grating sensor 531 and the grating strip 532.

[0101] In some optional embodiments, the nozzle guide rail 411 and the nozzle drive assembly 520 are both arranged on the side of the support beam 41 facing the print nozzle assembly 510, thereby providing sufficient space for the layout of the grating sensor 531 and the grating bar 532.

[0102] In order to facilitate the installation of the grating sensor 531 or the grating strip 532, in some optional embodiments, an extension portion 512 is provided on the print head assembly 510, and the extension portion 512 extends from the top of the support beam 41 to the side of the support beam 41 away from the print head assembly 510, and the grating sensor 531 or the grating strip 532 is installed on the extension portion 512, so as to facilitate the connection between the grating sensor 531 or the grating strip 532 and the print head assembly 510. In this embodiment, the grating sensor 531 and the second limit portion 511 are arranged at the bottom of the extension portion 512, and the grating strip 532 is arranged on the side of the support beam 41 away from the print head assembly 510.

[0103] In addition, due to the blocking of the extension part 512, the consumables can be further prevented from contacting the grating sensor 531 and the grating strip 532. In this embodiment, the extension part 512 is located above the grating sensor 531 and the grating strip 532, part 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 print head assembly 510, so the consumables can be blocked in three directions, which effectively prevents the consumables from contacting the grating sensor 531 and the grating strip 532.

[0104] In some optional embodiments, the extension portion 512 is connected to a drag chain mechanism 513, which is located on the side of the support beam 41 away from the print head assembly 510. The drag chain mechanism 513 is used to protect pipes and wires such as cables, oil pipes, and air pipes. Since the drag chain mechanism 513 is arranged on the side of the support beam 41 away from the print head assembly 510, consumables can be prevented from adhering to the drag chain mechanism 513 and to the pipes or wires inside the drag chain mechanism 513, which is beneficial for the drag chain mechanism 513 to operate smoothly while protecting the pipes and wires.

[0105] The specific structure of the nozzle guide track 411 can be appropriately designed according to actual needs. For example, the nozzle guide track 411 is a convex track, and the print nozzle assembly 510 slides with the convex track through a slider, but this example is not limited to this.

[0106] The specific structure of the nozzle drive assembly 520 can be appropriately designed according to actual needs. For example, the nozzle 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. In this embodiment, the nozzle drive assembly 520 adopts a belt translation drive assembly, and the belt structure is arranged on the side of the support beam 41 facing the print nozzle assembly 510. The belt drive motor is arranged on the side of the support beam 41 away from the print nozzle assembly 510 and is drivingly connected to the belt structure. The belt structure is drivingly connected to the print nozzle assembly 510.

[0107] See also Fig.13 and Fig.14 The specific structure of the mobile phone case shaping jig 60 can be appropriately designed according to actual needs. For example, the mobile phone case shaping jig 60 includes: a mobile phone case shaping seat 610 and a positioning component 620.

[0108] The positioning component 620 is disposed on the mobile phone case shaping seat 610 and is used to push the mobile phone case 90 to move to a preset shaping position 611 on the mobile phone case shaping seat 610 .

[0109] The positioning assembly 620 includes a positioning drive assembly 621 and four positioning members 622 . The four positioning members 622 are arranged on the mobile phone case shaping seat 610 and are respectively located on four sides of the shaping position 611 .

[0110] The positioning drive assembly 621 drives the positioning members 622 located on the two adjacent sides of the shaping position 611 to move relative to the mobile phone case shaping seat 610, or the positioning drive assembly 621 drives the positioning members 622 located on the three adjacent sides of the shaping position 611 to move relative to the mobile phone case shaping seat 610, or the positioning drive assembly 621 drives four positioning members 622 to move relative to the mobile phone case shaping seat 610, so that the corresponding positioning members 622 are close to or away from the shaping position 611. When the positioning is completed, the four positioning members 622 are correspondingly located at the sides of the shaping position 611, thereby limiting the mobile phone case 90 in the shaping position 611. The positioning drive assembly 621 can drive the mobile phone case shaping seat 610 to move so that the positioning member 622 is close to or away from the shaping seat, and can also drive the positioning member 622 to move toward the shaping seat so that the positioning member 622 is close to or away from the shaping position 611. In this embodiment, the driving connection between the positioning drive assembly 621 and the positioning member 622 is used as an example for explanation, and the positioning member 622 driven by the positioning drive assembly 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, so as to meet the structural design requirements.

[0111] See also Fig.15When 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 mobile phone case shaping seat 610. At this time, two of the positioning members 622 are fixed positioning members 6222, and the fixed positioning members 6222 are fixed relative to the position of the mobile phone case shaping seat 610. The fixed positioning members 6222 can be fixed on the mobile phone case shaping seat 610. The fixed positioning members 6222 can be arranged correspondingly at the side edges of the shaping position 611 to facilitate positioning of the mobile phone case 90. The other two positioning members 622 are movable positioning members 6221. After the mobile phone case 90 is placed on the mobile phone case shaping seat 610, the positioning drive assembly 621 can drive the movable positioning member 6221 to move, so that the movable positioning member 6221 moves toward the shaping position 611 until the movable positioning member 6221 pushes the mobile phone case 90 toward the shaping position 611, and the four sides of the mobile phone case 90 respectively abut against the two fixed positioning members 6222 and the two movable positioning members 6221. In this embodiment, the positioning drive assembly 621 is drivingly connected to the movable positioning member 6221.

[0112] See also Fig.16 When the second positioning method is adopted: the positioning drive component 621 drives the positioning members 622 located on the three sides adjacent to the shaping position 611 to move relative to the mobile phone case shaping seat 610. At this time, one of the positioning members 622 is a fixed positioning member 6222. The position of the fixed positioning member 6222 is fixed relative to the mobile phone case shaping seat 610. The fixed positioning member 6222 can be fixed on the mobile phone case shaping seat 610. The fixed positioning member 6222 can be arranged corresponding to the side edge of the shaping position 611 to facilitate positioning of the mobile phone case 90. The other three positioning members 622 are movable positioning members 6221. After the mobile phone case 90 is placed on the mobile phone case shaping seat 610, the positioning drive assembly 621 drives the movable positioning piece 6221 to move, so that the movable positioning piece 6221 moves toward the shaping position 611 until the movable positioning piece 6221 pushes the mobile phone case 90 toward the shaping position 611, and makes the four sides of the mobile phone case 90 respectively abut against a fixed positioning piece 6222 and three movable positioning pieces 6221, thereby realizing the positioning of the mobile phone case 90.

[0113] See also Fig.17 When the third positioning method is adopted: the positioning drive assembly 621 drives the positioning members 622 located on the four sides adjacent to the shaping position 611 to move relative to the mobile phone case shaping seat 610, and the four positioning members 622 are all movable positioning members 6221. After the mobile phone case 90 is placed on the mobile phone case shaping seat 610, the positioning drive assembly 621 drives the four movable positioning members 6221 to move, so that the positioning members 622 move toward the shaping position 611 until the movable positioning members 6221 push the mobile phone case 90 toward the shaping position 611, and the four sides of the mobile phone case 90 respectively abut against the four movable positioning members 6221.

[0114] In some optional embodiments, the sides of any two adjacent positioning members 622 used to position the mobile phone case 90 are perpendicular to each other. If the mobile phone case 90 is tilted relative to the side of the positioning member 622 used to position the mobile phone case 90, after the side of the positioning member 622 abuts against the mobile phone case 90, when the positioning member 622 pushes the mobile phone case 90 to move to the shaping position 611, the mobile phone case 90 will be driven to gradually be flush with the side corresponding to the shaping position 611, so that the mobile phone case 90 is accurately positioned.

[0115] In this embodiment, the positioning drive component 621 is driven and connected to the positioning member 622, wherein the positioning member 622 connected to the positioning drive component 621 is a movable positioning member 6221, and the movable positioning member 6221 is movably connected to the mobile phone case shaping seat 610 and is relatively movable with the mobile phone case shaping seat 610.

[0116] See also Fig.14 and Fig.18 In some optional embodiments, the positioning drive assembly 621 further includes a plurality of positioning power modules 6211, and the positioning power modules 6211 are correspondingly connected to the movable positioning member 6221 for driving, and the positioning power modules 6211 drive the movable positioning member 6221 to move closer to or away from the shaping position 611. The positioning power modules 6211 correspondingly drive the movable positioning member 6221 to move, so as to facilitate precise control of the movable positioning member 6221. Of course, in other embodiments, according to the number of movable positioning parts 6221, for example, when the number of movable positioning parts 6221 is two, the positioning drive assembly 621 may include only one positioning power module 6211, and the positioning power module 6211 may simultaneously drive the two movable positioning parts 6221 to move, thereby reducing the complexity of the structure; or, when the number of movable positioning parts 6221 is three, the positioning drive assembly 621 may include two positioning power modules 6211, one of which is driven and connected to one movable positioning part 6221, and the other positioning power module 6211 is driven and connected to the two movable positioning parts 6221; or, when the number of movable positioning parts 6221 is four, the positioning drive assembly 621 may include two positioning power modules 6211, and the positioning power module 6211 is driven and connected to the two movable positioning parts 6221.

[0117] See also Fig.18The specific structure of the positioning power module 6211 can be appropriately designed 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 is drivingly connected to the positioning transmission gear 62112. The movable positioning member 6221 is provided with a rack portion 62211. The positioning transmission gear 62112 is meshed 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 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., without limitation to this example.

[0118] In some optional embodiments, the moving direction of the movable positioning member 6221 is perpendicular to the side surface of the mobile phone case 90, and the moving direction of the second positioning member 622 is perpendicular to the side surface of the mobile phone case 90, thereby facilitating matching the side surface of the mobile phone case 90 so that the mobile phone case 90 is stably positioned.

[0119] In order to facilitate the installation of the positioning drive component 621 and prevent the positioning drive component 621 from being affected by dust and impurities in the environment, in some optional embodiments, the mobile phone case shaping seat 610 is also provided with an installation cavity 612 and a plurality of guide grooves 613. The plurality of guide grooves 613 are arranged around the shaping position 611 and are connected to the installation cavity 612. The positioning drive component 621 is arranged in the installation cavity 612, and the movable positioning member 6221 is slidably matched with the guide groove 613. A portion of the movable positioning member 6221 extends into the installation cavity 612 and is then driven and connected to the positioning drive component 621. The guide groove 613 can guide the movable positioning member 6221 to slide stably, thereby improving the movement stability of the movable positioning member 6221.

[0120] In some optional embodiments, a shielding plate 62212 is provided on the movable positioning member 6221, and the shielding plate 62212 is located in the installation cavity 612. The shielding plate 62212 closes at least part of the guide slot 613, and the shielding plate 62212 moves with the movable positioning member 6221. When the mobile phone case 90 is not positioned, the shielding plate 62212 can prevent dust and other impurities in the environment from entering the installation cavity 612 from the guide slot 613, thereby improving the protection of the positioning drive assembly 621. In this embodiment, the rack portion 62211 is provided on the shielding plate 62212.

[0121] In some optional embodiments, a mobile phone shell shaping seat 610 is provided with a mobile phone shell detection component 614, which faces the shaping position 611 and is connected to the positioning drive component 621 by signal. The mobile phone shell detection component 614 is used to detect whether the mobile phone shell 90 is placed at the shaping position 611. When the mobile phone shell detection component 614 detects the mobile phone shell 90, the mobile phone shell detection component 614 sends a positioning signal to the positioning drive component 621, and then the positioning component 620 positions the mobile phone shell 90. The mobile phone shell detection component 614 can use a photoelectric sensor, an infrared sensor, an ultrasonic sensor, a proximity switch, etc. The detection methods such as photoelectric sensors, infrared sensors, ultrasonic sensors, proximity switches, etc. are well known to those skilled in the art and will not be described in detail here.

[0122] See also Fig.19 and Fig. 20 In some optional embodiments, the height adjustment mechanism 70 includes:

[0123] The lifting drive assembly 710 is connected to the mobile phone shell shaping seat 610 of the mobile phone shell shaping jig 60 and is used to drive the mobile phone shell shaping seat 610 of the mobile phone shell shaping jig 60 to lift;

[0124] The height detection component 720 is used to detect whether the mobile phone shell 90 has reached the preset height. The height detection component 720 is arranged on one side of the mobile phone shell shaping fixture 60 and is connected to the lifting drive component 710 by signal. The height of the mobile phone shell shaping seat 610 is adjusted by the lifting drive component 710, and then the height of the mobile phone shell 90 is adjusted. The height detection component 720 is used to determine whether the mobile phone shell 90 has reached the preset height. After the lifting drive component 710 drives the mobile phone shell shaping seat 610 to rise and fall so that the mobile phone shell 90 reaches the preset height, the printing mechanism can print on the mobile phone shell 90. The height of the mobile phone shell shaping seat 610 is adjusted by the lifting drive component 710 to adapt to the thickness difference of different mobile phone shells 90, so as to avoid affecting the printing effect due to the thickness difference of different mobile phone shells 90. The overall structure is relatively simple and the cost is low.

[0125] It should be noted that when the mobile phone case 90 is at a preset height, the distance between the top surface of the mobile phone case 90 and the printing mechanism 50 enables the printing mechanism 50 to perform effective printing. The top surface of the mobile phone case 90 will not be too far or too close to the printing mechanism 50 to affect the printing effect, and the printing mechanism 50 and the mobile phone case 90 will not collide with each other.

[0126] In some optional embodiments, the mobile phone case printing device 30 also includes a conveying mechanism 80, which is disposed on the bracket 40 and is driven and connected to the height adjustment mechanism 70 to drive the height adjustment mechanism 70 to move relative to the printing mechanism 50 to a loading position and a printing position.

[0127] The height adjustment mechanism 70 is moved as a whole to a loading position away from the printing mechanism 50 by the conveying mechanism 80, so as to facilitate the placement of the mobile phone case 90 on the mobile phone shaping seat, and to prevent the printing mechanism 50 from interfering with the placement process of the mobile phone case 90. After the mobile phone case 90 is placed, the conveying mechanism 80 conveys the mobile phone case 90 to the printing position below the printing mechanism 50, so as to facilitate printing on the mobile phone case 90. In the latter embodiment, the printing position and the loading position are arranged in sequence in the direction close to the storage and transportation mechanism 20 of the mobile phone case 90, so as to facilitate the storage and transportation mechanism 20 of the mobile phone case 90 to quickly place the mobile phone case 90 on the mobile phone case shaping jig 60, and shorten the moving path of the mobile phone case 90.

[0128] Among them, when the conveying mechanism 80 drives the height adjustment mechanism 70 to move from the loading position to the printing position, the height of the mobile phone case 90 can be adjusted. If the height detection component 720 detects that there is a mobile phone case 90 at the preset height, the lifting drive component 710 drives the mobile phone case shaping jig 60 to slowly descend until the height detection component 720 just fails to detect the mobile phone case 90 at the preset height, and the mobile phone case shaping jig 60 immediately stops descending, so that the top surface of the mobile phone case 90 is just at the preset height; if the height detection component 720 does not detect the presence of the mobile phone case 90 at the preset height, the lifting drive component 710 drives the mobile phone case shaping jig 60 to rise until the height detection component 720 detects that there is a mobile phone case 90 at the preset height, and then the lifting drive component 710 drives the mobile phone case shaping jig 60 to slowly descend again, until the height detection component 720 just fails to detect the mobile phone case 90 at the preset height, and the mobile phone case shaping jig 60 immediately stops descending, so that the top surface of the mobile phone case 90 is just at the preset height.

[0129] The specific method in which the height detection component 720 determines whether the height of the mobile phone case 90 reaches the preset height can be appropriately designed 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, and the light emitter 721 and the light receiver 722 are respectively arranged on both sides of the mobile phone case shaping jig 60. The light emitter 721 can be of different types, such as an infrared light emitter 721, a visible light emitter 721, and the like. In this embodiment, the light transmitter 721 is a laser transmitter and the light receiver 722 is a laser receiver. The laser transmitter and the laser receiver are arranged at a preset height and located between the loading position and the printing position. They are used 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 transmitter, 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 transmitter, it means that the mobile phone case 90 is detected, which means that the height of the mobile phone case 90 exceeds the preset height. The laser transmitter sends a signal to the lifting drive assembly 710, and the lifting drive assembly 710 drives the mobile phone case shaping jig 60 to slowly descend until the laser receiver receives the laser emitted by the laser transmitter. The lifting drive assembly 710 drives the mobile phone case shaping jig 60 to slowly descend. The assembly 710 stops descending immediately, and the mobile phone shell 90 is just not detected at this time, and the mobile phone shell 90 is just at the preset height; if the laser transmitter receives the laser emitted by the laser transmitter, it means that the mobile phone shell 90 is not detected, which means that the height of the mobile phone shell 90 is lower than the preset height, and the laser transmitter sends a signal to the lifting drive assembly 710, and the lifting drive assembly 710 drives the mobile phone shell plastic shaping fixture 60 to rise until the laser receiver does not receive the laser, and the height of the mobile phone shell 90 exceeds the preset height, and then the laser transmitter sends a signal to the lifting drive assembly 710, and the lifting drive assembly 710 drives the mobile phone shell plastic shaping fixture 60 to slowly descend until the laser transmitter just receives the laser, that is, the mobile phone shell 90 is just not detected, and the lifting drive assembly 710 stops descending immediately, and the mobile phone shell 90 is just at the preset height. The conveying mechanism 80 and the height adjustment mechanism 70 can operate simultaneously, that is, when 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 mobile phone shell 90, thereby improving work efficiency.

[0130] Or in some other optional embodiments, the height detection component 720 includes a distance sensor, which is arranged above the mobile phone shaping seat and faces the top of the mobile phone shaping seat, and faces the mobile phone shell 90 on the mobile phone shell shaping fixture 60. By detecting the distance between the mobile phone shell 90 and the distance sensor, it is determined whether the mobile phone shell 90 reaches a preset height. The distance sensor can use different types of detection methods, such as proximity switches, infrared distance sensors, etc., without limitation.

[0131] Or in some other optional embodiments, the height detection component 720 includes a thickness measuring sensor, and the distance measuring sensor is arranged on one side of the mobile phone case shaping jig 60, which can detect the thickness of the mobile phone case 90. Since the area to be printed on the mobile phone case 90 is usually located at the top of the mobile phone case 90, the preset height minus the thickness of the mobile phone case 90 can be obtained to obtain the height that the mobile phone case shaping jig 60 needs to be raised, thereby allowing the mobile phone case shaping jig 60 to be raised until the mobile phone case 90 reaches the preset height.

[0132] Or in some other optional embodiments, the height detection component 720 includes a contact sensor, and determines whether the mobile phone case reaches the preset height by judging whether the mobile phone case just touches the contact sensor located at the preset height.

[0133] Or in some other optional embodiments, the height detection component 720 includes a mobile phone case height calculation unit connected to the signal of the lifting drive component 710. The height to which the lifting drive component 710 drives the mobile phone case shaping seat 610 to rise and fall and the current height of the mobile phone case shaping seat 610 can be calculated in real time. For example, when the lifting drive component 710 uses a motor as a power source, the current height of the mobile phone case shaping seat 610 can be determined in real time through the operating data of the motor. Since the size specifications (length, width and thickness) placed on the mobile phone case 90 can be obtained and stored in advance, after the user selects the corresponding model of the mobile phone case 90, the mobile phone case storage and handling mechanism transports the mobile phone case 90, and the mobile phone case height calculation unit receives the thickness information of the mobile phone case 90 selected by the user, based on the thickness of the mobile phone case 60 itself plus the current height of the mobile phone case shaping seat 610, the current height of the mobile phone case 90 can be measured in real time. The lifting drive component 710 adjusts the height of the mobile phone case shaping seat 610 based on the current height of the mobile phone case 90, so that the mobile phone case 90 reaches a preset height. The mobile phone case height calculation unit can use components such as a processor and a computing circuit to implement the calculation function.

The synchronous belt 7131 located in the assembly cavity 7112 is meshed with the first guide synchronous wheel 7134, multiple transmission synchronous wheels 7133 and the second guide synchronous wheel 7135 in sequence. In order to enable the synchronous belt 7131 to maintain tightness without generating friction with the assembly port 7115, the first guide synchronous wheel 7134 and the second guide synchronous wheel 7135 are used to guide the synchronous belt 7131 to turn near the assembly port 7115, so that the synchronous belt 7131 can pass through the assembly port 7115 smoothly, so that the size of the assembly port 7115 can be designed to be relatively small, thereby improving the protection performance of the assembly cavity 7112. The synchronous belt 7131 passes through the active synchronous wheel 7132, the first guide synchronous wheel 7134, multiple transmission synchronous wheels 7133 and the second guide synchronous wheel 7135 in sequence, and then returns to the active synchronous wheel 7132.
