In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0054] Please refer to Figure 1 The utility model discloses an embodiment provides a kind of mobile phone shell printing device, it include: support 10, printing mechanism 20, mobile phone shell shaping fixture 30, height adjusting mechanism 40 and conveying mechanism 50.

[0055] The printing mechanism 20 is arranged on the support 10, and is used for printing the mobile phone shell.

[0056] The mobile phone shell shaping fixture 30 is arranged below the printing mechanism 20, and is used for positioning the mobile phone shell, so that the printing mechanism 20 can accurately print the mobile phone shell.

[0057] The height adjusting mechanism 40 is drivingly connected with the mobile phone shell shaping fixture 30, drives the mobile phone shell shaping fixture 30 to ascend and descend, can adjust the height of the mobile phone shell on the mobile phone shell shaping fixture 30, so that the mobile phone shell and the printing mechanism 20 maintain appropriate spacing, thereby avoiding the thickness difference of different mobile phone shells affecting the printing effect, the overall structure is relatively simple, and the cost is relatively low.

[0058] The conveying mechanism 50 is arranged on the bracket 10 and is drivingly connected with the height adjusting mechanism 40 to drive the height adjusting mechanism 40 to move close to or away from the printing mechanism 20. The conveying mechanism 50 moves the height adjusting mechanism 40 as a whole to a position away from the printing mechanism 20 to facilitate the placement of the phone case on the phone shaping seat, avoiding the printing mechanism 20 from interfering with the placement process of the phone case. After the phone case is placed, the conveying mechanism 50 conveys the phone case to the position below the printing mechanism 20 to facilitate the printing of the phone case.

[0059] When printing, the phone case is placed on the phone case shaping jig 30, and then the conveying mechanism 50 moves the height adjusting mechanism 40 to the position of the printing mechanism 20, so that the phone case shaping jig 30 is located below the printing mechanism 20. Then the height adjusting mechanism 40 adjusts the height of the phone case shaping jig 30, so that the phone case is at a height suitable for printing by the printing mechanism 20. After printing is completed, the conveying mechanism 50 moves the height adjusting mechanism 40 to a position away from the printing mechanism 20, and then removes the printed phone case from the phone case shaping jig 30.

[0060] The specific structure of the conveying mechanism 50 can be selected according to actual needs, for example, the conveying mechanism 50 can adopt a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a pneumatic cylinder translation drive assembly, or a linear motor translation drive assembly, etc. In the present embodiment, the conveying mechanism 50 adopts a synchronous belt 4131 translation drive assembly.

[0061] Please refer to Figures 2 to 4 The specific structure of the printing mechanism 20 can be selected according to actual needs, for example, the printing mechanism 20 includes a printing nozzle assembly 210, a nozzle drive assembly 220, a position detection assembly 230, and a support beam 11.

[0062] The support beam 11 is provided with a nozzle guide rail 111.

[0063] The printing nozzle assembly 210 is movably connected with the nozzle guide rail 111, and the printing nozzle assembly 210 and the position detection assembly 230 are arranged on the two sides of the support beam 11, respectively.

[0064] The nozzle drive assembly 220 is drivingly connected with the printing nozzle assembly 210 to drive the printing nozzle assembly 210 to move along the nozzle guide rail 111.

[0065] The printing head assembly 210 and the position detection assembly 230 are arranged on two sides of the support beam 11 respectively, and the support beam 11 can block the consumables, so that the consumables sprayed by the printing head assembly 210 are prevented from adhering to the position detection assembly 230, thereby effectively preventing the position detection assembly 230 from being contaminated by the consumables and causing the inductance to be insensitive or even inductance failure, avoiding the need to frequently replace / clean the position detection assembly 230, and effectively reducing the number of maintenance.

[0066] The specific structure of the position detection assembly 230 can be selected according to actual needs, for example, the position detection assembly 230 can be an optical distance measuring sensor assembly or an infrared distance measuring sensor assembly, etc. In the embodiment, the position detection assembly 230 includes a grating sensor 231 and a grating strip 232, the grating sensor 231 and the grating strip 232 are inductively matched, the grating sensor 231 and the grating strip 232 are arranged on the side of the support beam 11 away from the printing head assembly 210, the grating sensor 231 is connected with the printing head assembly 210, and the grating strip 232 is arranged on the side of the support beam 11 away from the printing head assembly 210. Benefiting from the blocking of the support beam 11, the consumables sprayed by the printing head assembly 210 are prevented from adhering to the grating sensor 231 or the grating strip 232, especially the grating strip 232, because the grating strip 232 is relatively long, and the surface of the grating strip 232 needs to be kept smooth due to the inductive distance between the grating strip 232 and the grating sensor 231. Of course, the position detection assembly 230 can also adopt other suitable structures, and is not limited to the grating sensor 231 and the grating strip 232.

[0067] In some optional embodiments, two grating fixing frames 112 are arranged on the side of the support beam 11 away from the printing head assembly 210, and the grating strip 232 is mounted on the two grating fixing frames 112, and the grating sensor 231 is located between the two grating fixing frames 112. The grating fixing frame 112 facilitates the installation of the grating strip 232 and maintains the shape of the grating strip 232.

[0068] Please refer to Figure 4 and Figure 5 In some optional embodiments, a first limiting portion 113 is formed on the grating fixing frame 112, and two second limiting portions 211 are arranged on the printing head assembly 210, the two second limiting portions 211 are located on two sides of the grating sensor 231 respectively, the two second limiting portions 211 are located between the two first limiting portions 113, the first limiting portion 113 corresponds to and limits the second limiting portion 211, and when the grating sensor 231 moves to the limit position, the first limiting portion 113 and the second limiting portion 211 abut against each other to limit the position of the grating sensor 231 relative to the grating strip 232.

[0069] Referring to Figure 6 and Figure 7 In some alternative embodiments, the printing mechanism 20 further comprises a protective cover 240, which forms a printing space 241 on the side of the support beam 11 facing the printing head assembly 210 and below the printing head assembly 210, and is used to block the consumables sprayed by the printing head assembly 210, further effectively preventing the sprayed consumables from bypassing the support beam 11 and adhering to the grating sensor 231 or the grating bar 232.

[0070] In some alternative embodiments, part of the protective cover 240 is arranged on the side of the support beam 11 away from the printing head assembly 210 and below the grating sensor 231 and the grating bar 232. Since the printing space 241 is on the side of the support beam 11 facing the printing head assembly 210 and below the printing head assembly 210, the sprayed consumables mainly spread from below the support beam 11, and the protective cover 240 protects the grating sensor 231 and the grating bar 232 below, which can further prevent the consumables from contacting the grating sensor 231 and the grating bar 232 in cooperation with the support beam 11. When the printing mechanism 20 prints the phone case, the phone case shaping jig 30 is located in the printing space 241. After printing is completed, the conveying mechanism 50 drives the height adjusting mechanism 40 to move to drive the phone case shaping jig 30 to leave the printing space 241, or the printing space 241 can also be designed to be large enough, so that part of the printing space 241 is located directly below the printing mechanism 20, and the other part is located below the side of the printing mechanism 20, so that the phone case shaping jig 30 is always located in the printing space 241, and the conveying mechanism 50 moves the phone case shaping jig 30 to the position where the printing space 241 is located below the side of the printing mechanism 20, and the phone case can also be placed or taken out to avoid the printing mechanism 20 hindering the movement of the phone case.

[0071] In some alternative embodiments, the nozzle guide rail 111 and the nozzle driving assembly 220 are both arranged on the side of the support beam 11 facing the printing head assembly 210, thereby providing sufficient space for the layout of the grating sensor 231 and the grating bar 232.

[0072] In order to facilitate the installation of the grating sensor 231 or the grating strip 232, in some optional embodiments, an extension 212 is arranged on the print head assembly 210, the extension 212 extends from above the support beam 11 to a side of the support beam 11 away from the print head assembly 210, and the grating sensor 231 or the grating strip 232 is installed on the extension 212, so as to facilitate the connection of the grating sensor 231 or the grating strip 232 with the print head assembly 210. In the embodiment, the grating sensor 231 and the second limiting portion 211 are arranged at the bottom of the extension 212, and the grating strip 232 is arranged at the side of the support beam 11 away from the print head assembly 210.

[0073] In addition, due to the blocking of the extension 212, the consumables can also be further prevented from contacting the grating sensor 231 and the grating strip 232. In the embodiment, the extension 212 is located above the grating sensor 231 and the grating strip 232, part of the protective cover 240 is located below the grating sensor 231 and the grating strip 232, and the support beam 11 is located at the side of the grating sensor 231 and the grating strip 232 facing the print head assembly 210, so that the consumables can be blocked in three directions, and the consumables can be effectively prevented from contacting the grating sensor 231 and the grating strip 232.

[0074] In some optional embodiments, the extension 212 is connected with a drag chain mechanism 213, the drag chain mechanism 213 is located at the side of the support beam 11 away from the print head assembly 210, and the drag chain mechanism 213 is used for protecting the pipes and wires such as cables, oil pipes and gas pipes. Since the drag chain mechanism 213 is arranged at the side of the support beam 11 away from the print head assembly 210, the consumables can also be prevented from adhering to the drag chain mechanism 213 and the pipes or wires in the drag chain mechanism 213, so as to facilitate the smooth operation of the drag chain mechanism 213 and protect the pipes and wires.

[0075] The specific structure of the print head guide rail 111 can be selected according to actual needs, for example, the print head guide rail 111 is a convex rail, and the print head assembly 210 is slidably connected with the convex rail through a sliding block, which is not limited to this example.

[0076] The specific structure of the print head driving assembly 220 can be selected according to actual needs, for example, the print head driving assembly 220 can adopt a screw driving assembly, a rotary motor translation driving assembly, a belt translation driving assembly, a gas cylinder translation driving assembly or a linear motor translation driving assembly, etc. In the embodiment, the print head driving assembly 220 adopts a belt translation driving assembly, a belt structure is arranged at the side of the support beam 11 facing the print head assembly 210, a belt driving motor is arranged at the side of the support beam 11 away from the print head assembly 210 and is drivingly connected with the belt structure, and the belt structure is drivingly connected with the print head assembly 210.

[0077] Please refer toFigure 8 and Figure 9 The specific structure of the mobile phone shell shaping jig 30 can be selected according to actual needs, for example, the mobile phone shell shaping jig 30 comprises a mobile phone shell shaping seat 310 and a positioning assembly 320.

[0078] The positioning assembly 320 is arranged on the mobile phone shell shaping seat 310 and is used to push the mobile phone shell 60 to move to a preset shaping position 311 on the mobile phone shell shaping seat 310.

[0079] The positioning assembly 320 comprises a positioning driving assembly 321 and four positioning pieces 322, the four positioning pieces 322 are arranged on the mobile phone shell shaping seat 310 and are respectively located at four sides of the shaping position 311.

[0080] The positioning driving assembly 321 drives the positioning pieces 322 located at adjacent two sides of the shaping position 311 to move relative to the mobile phone shell shaping seat 310, or the positioning driving assembly 321 drives the positioning pieces 322 located at adjacent three sides of the shaping position 311 to move relative to the mobile phone shell shaping seat 310, or the positioning driving assembly 321 drives the four positioning pieces 322 to move relative to the mobile phone shell shaping seat 310, so as to make the corresponding positioning pieces 322 close to or away from the shaping position 311. When the positioning is completed, the four positioning pieces 322 are respectively located at the sides of the shaping position 311, so as to limit the mobile phone shell 60 in the shaping position 311. The positioning driving assembly 321 can drive the mobile phone shell shaping seat 310 to move so that the positioning pieces 322 are close to or away from the shaping seat, or the positioning driving assembly 321 can drive the positioning pieces 322 to move to the shaping seat, so that the positioning pieces 322 are close to or away from the shaping position 311.

The mobile phone shell detection assembly 314 is used for detecting whether the mobile phone shell 60 is placed at the shaping position 311. When the mobile phone shell detection assembly 314 detects the mobile phone shell 60, the mobile phone shell detection assembly 314 sends a positioning signal to the positioning driving assembly 321, and then the positioning assembly 320 positions the mobile phone shell 60. The mobile phone shell detection assembly 314 can adopt photoelectric sensor, infrared sensor, ultrasonic sensor, proximity switch and the like. The detection modes of the photoelectric sensor, the infrared sensor, the ultrasonic sensor and the proximity switch are known to those skilled in the art, and will not be described here.

[0092] Please refer to Figure 14 and Figure 15 The specific structure of the height adjusting mechanism 40 can be selected according to actual needs, for example, the height adjusting mechanism 40 includes a lifting driving assembly 410 and a height detection assembly 420 for detecting whether the mobile phone shell 60 reaches a preset height.

[0093] The lifting driving assembly 410 is drivingly connected with the mobile phone shell shaping seat 310 of the mobile phone shell shaping jig 30, and is used for driving the mobile phone shell shaping seat 310 to lift; the height detection assembly 420 is in sensing cooperation with the mobile phone shell shaping seat 310 or the mobile phone shell 60 on the mobile phone shell shaping seat 310, and is in signal connection with the lifting driving assembly 410.

[0094] The printing mechanism 20 is arranged above the mobile phone shell shaping seat 310 of the mobile phone shell height adjusting mechanism 40, and the printing mechanism 20 can print patterns on the top surface of the mobile phone shell 60.

[0095] The height of the mobile phone shell shaping seat 310 is adjusted by the lifting driving assembly 410, so as to adjust the height of the mobile phone shell 60. Whether the mobile phone shell 60 reaches a preset height is judged by the height detection assembly 420. After the lifting driving assembly 410 drives the mobile phone shell shaping seat 310 to lift so that the mobile phone shell 60 reaches the preset height, the printing mechanism can print on the mobile phone shell 60. The height of the mobile phone shell shaping seat 310 is adjusted by the lifting driving assembly 410 to adapt to the thickness difference of different mobile phone shells 60, so as to avoid affecting the printing effect due to the thickness difference of different mobile phone shells 60. The overall structure is relatively simple, and the cost is relatively low.

[0096] It should be noted that when the mobile phone shell 60 is at the preset height, the distance between the mobile phone shell 60 and the printing mechanism 20 can enable the printing mechanism 20 to effectively print. The mobile phone shell 60 will not be too far or too close to the printing mechanism 20 to affect the printing effect, and the printing mechanism 20 and the mobile phone shell 60 will not collide.

[0097] In some alternative embodiments, the printing device further comprises a support 10, and the printing mechanism 20 and the conveying mechanism are arranged on the support 10.

[0098] The specific manner in which the height detection assembly 420 determines whether the height of the phone case 60 reaches the preset height can be selected according to actual needs, for example, in some alternative embodiments, the height detection assembly 420 comprises a light emitter 421 and a light receiver 422, which are arranged on both sides of the phone case shaping seat 310, respectively. The light emitter 421 can be selected in different types, for example, an infrared light emitter 421, a visible light emitter 421, etc. The light emitter 421 and the light receiver 422 are arranged at the preset height, for real-time detection of whether the phone case 60 exists at the preset height. In this embodiment, the light emitter 421 is taken as a laser emitter, and the light receiver 422 is taken as a laser receiver for illustration. The light receiver 422 judges whether the phone case 60 exists by detecting the light emitted by the light emitter 421, and further judges whether the height of the phone case 60 exceeds the preset height. If the light receiver 422 detects the phone case 60, it means that the height of the phone case 60 exceeds the preset height, and the laser emitter sends a signal to the lifting driving assembly 410, which drives the phone case shaping seat 310 to slowly descend until the light receiver 422 does not detect the phone case 60, at which time the lifting driving assembly 410 immediately stops descending, and at this time the phone case 60 is just at the preset height. If the light receiver 422 does not detect the phone case 60, it means that the height of the phone case 60 is lower than the preset height, and the light receiver 422 sends a signal to the lifting driving assembly 410, which drives the phone case shaping seat 310 to rise until the light receiver 422 detects the phone case 60, at which time the height of the phone case 60 exceeds the preset height, and then the light receiver 422 sends a signal to the lifting driving assembly 410, which drives the phone case shaping seat 310 to slowly descend until the light receiver 422 does not detect the phone case 60, at which time the lifting driving assembly 410 immediately stops descending, and at this time the phone case 60 is just at the preset height. The conveying mechanism 50 and the height adjusting mechanism 40 can operate simultaneously, that is, the height adjusting mechanism 40 adjusts the height of the phone case during the process in which the conveying mechanism 50 moves the phone case height adjusting mechanism 40 to the lower side of the printing mechanism 20, thereby improving the work efficiency.

[0099] In some alternative embodiments, the height detection assembly 420 includes a distance sensor, which is arranged above the phone case shaping seat and faces the top of the phone case shaping seat. The distance sensor faces the phone case 60 on the phone case shaping seat 310. By detecting the distance between the phone case 60 and the distance sensor, the height detection assembly 420 can determine whether the phone case 60 reaches the preset height. The distance sensor can be a proximity switch, an infrared distance sensor, or the like, without being limited thereto.

[0100] In some alternative embodiments, the height detection assembly 420 includes a thickness sensor, which is arranged on one side of the phone case shaping seat 310 and can detect the thickness of the phone case 60. Since the printing area of the phone case 60 is usually located at the top of the phone case 60, the height that the phone case shaping seat 310 needs to be raised can be obtained by subtracting the thickness of the phone case 60 from the preset height, so that the phone case shaping seat 310 is raised to the preset height.

[0101] In some alternative embodiments, the height detection assembly 420 includes a contact sensor. The height detection assembly 420 can determine whether the phone case reaches the preset height by judging whether the phone case just touches the contact sensor at the preset height.

[0102] In some alternative embodiments, the height detection assembly 420 includes a phone case height calculation unit that is signal-connected to the lifting driving assembly 410. The lifting driving assembly 410 drives the phone case shaping seat 310 to raise and lower. The current height of the phone case shaping seat 310 can be calculated in real time. For example, when the lifting driving assembly 410 uses a motor as a power source, the current height of the phone case shaping seat 310 can be determined in real time by the running data of the motor. Since the size (length, width, and thickness) of the phone case 60 placed on the phone case shaping seat 310 can be obtained and stored in advance, the current height of the phone case 60 can be calculated in real time by adding the thickness of the phone case 60 to the current height of the phone case shaping seat 310 after the phone case height calculation unit receives the thickness information of the phone case 60. The lifting driving assembly 410 adjusts the height of the phone case shaping seat 310 according to the current height of the phone case 60, so that the phone case 60 reaches the preset height. The phone case height calculation unit can be a processor, an arithmetic circuit, or the like.
