Technical Field

[0001] This invention relates to the field of inkjet printing equipment technology, and in particular to an inkjet printing device for mobile phone back covers. Background Technology

[0002] In recent years, people's demand for diverse mobile phone colors has led to the growing popularity of colorful phone back covers. Some existing mobile phones with wood grain, leather texture, and iridescent finishes achieve this by applying iridescent films to the back cover. However, due to process and system errors, light leakage is prone to occur at the glass edges after the film is applied, resulting in low yield and low production efficiency.

[0014] A second moving mechanism is disposed on the base;

[0015] A suction cup component is disposed in the second moving mechanism for picking up the mobile phone back cover located at the unloading station;

[0016] The second moving mechanism is used to: drive the suction cup component to move to the unloading station when the conveying device moves the back cover of the mobile phone to the unloading station so that the suction cup component picks up the back cover of the mobile phone, and drive the suction cup component to move the back cover of the mobile phone to the baking mechanism so that the suction cup component releases the back cover of the mobile phone to the baking mechanism.

[0017] In some embodiments, the baking mechanism includes:

[0040] This invention proposes a printing device for mobile phone back covers, with reference to... Figures 1-4 The printing equipment for the back cover of the mobile phone includes:

[0041] The base 100 is equipped with a printing station and a material unloading station.

[0042] The conveying device 200 is set on the base 100 and is used to carry the mobile phone back cover 500 and convey the mobile phone back cover 500 to the printing station and the unloading station respectively.

[0043] The printing device 300 is mounted on the base 100 and is used to print on the light leakage points on the back cover 500 of the mobile phone located at the printing station.

[0044] The unloading device 400 is set on the base 100 and is used to unload the mobile phone back cover 500 that has been printed by the inkjet printing device 300 and is located at the unloading station.

[0045] The base 100 provides support for other mechanisms of the equipment, ensuring their stable installation and operation, and providing sufficient space for cooperation between them, thus guaranteeing the continuity and efficiency of the entire assembly process. The base 100 can be a frame structure or a seat structure. The frame structure is typically made of metal (such as aluminum alloy or steel), providing high strength and stability. Other mechanisms can be installed within the frame structure or mounted on its sides, offering greater installation flexibility. The seat structure includes a three-dimensional load-bearing structure with a worktable on its upper surface. Other structures are mounted on the upper surface or sides of the base 100. The bottom of the base 100 can be equipped with shock-absorbing or mounting structures, such as cushioning pads or feet, allowing the base 100 to adapt to various installation environments. The base 100 can be made of materials such as stainless steel or aluminum alloy, but is not limited to these. Preferably, a cover can be installed on the base 100 to protect the internal structure from external environmental influences, creating a closed processing environment that effectively prevents the entry of harmful substances such as wastewater with irritating odors or dust generated during processing.

[0046] The conveying device 200 is used to move the mobile phone back cover 500 to a suitable position, thereby completing processes such as printing and unloading. For example, the conveying device 200 can be a conveyor belt structure, where the mobile phone back cover 500 is placed on the conveyor belt manually or automatically. The conveyor belt then moves under the drive of the drive wheels and driven wheels, thereby moving the mobile phone back cover 500 to the printing station or the unloading station. This allows for continuous, large-volume conveying of the mobile phone back cover 500, with a simple structure and convenient maintenance. Alternatively, the conveying device 200 can be a robotic arm structure, where the robotic arm grips the mobile phone back cover 500, and a control system connected to the robotic arm controls its movements to move the mobile phone back cover 500. The back cover 500 can be moved to the printing station or the unloading station, offering greater flexibility and applicability to various models of mobile phone back covers 500. The conveying device 200 can also be a slide rail slider structure, where the slider carries the mobile phone back cover 500 and can slide on the slide rail under the drive of a motor, thereby moving the mobile phone back cover 500 to the printing station or the unloading station. The conveying accuracy is high, enabling precise transportation of the mobile phone back cover 500. This invention does not limit the type or setting of the conveying device 200, and designers can make reasonable designs according to actual needs.

[0047] After the printing process of the phone back cover 500 at the printing position is completed, the phone back cover 500 needs to be removed from the conveyor 200 by the unloading device 400. For example, the unloading device 400 can be a slide structure. By setting a slide near the unloading station, the phone back cover 500 that has moved to the unloading station can be moved to other collection containers by the slide. The structure is simple and the cost is low. The unloading device 400 can also be a robotic arm structure. The robotic arm removes the phone back cover 500 and places it in a designated position, which is more flexible. The present invention does not limit the type and setting method of the unloading device 400. Designers can make reasonable designs according to actual needs.

[0048] In operation, the phone back cover 500 is first placed on the conveyor 200 manually or automatically. The conveyor 200 then moves the phone back cover 500 to the printing station, where the printing device 300 prints the light-leaking points on the phone back cover 500. At this time, the conveyor 200 can be stopped or still in motion, allowing the printing device 300 to print on the phone back cover 500 while in motion. After printing, the conveyor 200 continues to move the phone back cover 500 to the unloading station, where the unloading device 400 unloads the phone back cover 500. Understandably, to ensure the above operations are completed at appropriate times, a control device can be installed to control the operation of the conveyor 200, printing device 300, and unloading device 400, allowing them to cooperate and improve work efficiency.

[0049] This invention provides a mobile phone back cover printing device that allows back covers 500 with light leakage points to be printed using the printing device 300, thus completing the reprocessing of the back cover 500 and improving the yield rate. Furthermore, the conveying device 200 in this invention can automatically move the back cover 500 between the printing station and the unloading station, greatly improving automation, reducing the workload of workers, and increasing work efficiency.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the printing device 300 includes a first moving mechanism 310 and a printing head 320. The first moving mechanism 310 is disposed on the base 100, and the printing head 320 is disposed on the first moving mechanism 310. The first moving mechanism 310 is used to drive the printing head 320 to move, and the printing head 320 is used to print on the light leakage points.

[0051] Specifically, when the conveying device 200 moves the phone back cover 500 to the printing station, the first moving mechanism 310 controls the inkjet head 320 to move to the top or side of the phone back cover 500, so that the inkjet head 320 can complete the printing of the light leak points on the phone back cover 500. If there are multiple light leak points on the phone back cover 500, the first moving mechanism 310 moves the inkjet head 320 to the next light leak point position according to the preset path, and repeats the printing operation until all light leak points are printed. After the printing of one phone back cover 500 is completed, the first moving mechanism 310 can drive the inkjet head 320 back to the initial position or directly continue the printing work of the next phone back cover 500 and repeat the above process until the phone back cover printing equipment is turned off.

[0052] The printhead 320 typically includes at least one printhead, which can be connected to a structure such as an ink reservoir to provide ink. For example, in this embodiment, two printheads are arranged side-by-side, and the printheads can be detachably connected to the first moving mechanism 310 via at least one of the following methods: screwing, snap-fitting, or gluing; or they can be non-detachably connected to the first moving mechanism 310 via at least one of the following methods: welding, bonding, etc.

[0053] There are various ways to configure the first moving mechanism 310, and designers can make a reasonable design according to actual needs. For example, the first moving mechanism 310 can be a linear motor, a lead screw structure, or a guide rail structure that moves in a straight line. Taking the guide rail structure as an example, the movement of the print head 320 is realized through the sliding connection between the print head 320 and the guide rail structure. In this case, a cylinder can be used as the drive, so that the print head 320 can be connected to the telescopic rod of the cylinder. The speed and position of the print head 320 are controlled by the extension and retraction of the telescopic rod. The configuration of the linear motor and lead screw structure is similar, and will not be described in detail here. Preferably, in this embodiment, the first moving mechanism 310 is a three-axis moving platform, including a bracket mounted on the base 100, and an X-axis module 311, a Y-axis module 312, and a Z-axis module 313 mounted on the bracket. Specifically, the print head 320 is mounted on the Z-axis module 313, the X-axis module 311 is mounted on the bracket and is used to drive the Y-axis module 312 and the Z-axis module 313 to move along the XX' direction, the Y-axis module 312 is mounted on the X-axis module 311 and is used to drive the Z-axis module 313 to move along the YY' direction, and the Z-axis module 313 is mounted on the Y-axis module 312 and is used to drive the print head 320 to move along the ZZ' direction, thereby realizing the three-axis movement of the print head 320. The movement of the print head 320 is more precise and can be height-adjusted according to the model of the mobile phone back cover 500, thus adapting to more usage environments.

[0054] In some embodiments, the printing apparatus 300 further includes a CCD positioning mechanism, which is disposed on the base 100 and is communicatively connected to the first moving mechanism 310. When the conveying device 200 moves the mobile phone back cover 500 to the printing station, the CCD positioning mechanism is located above the mobile phone back cover 500 to detect light leakage points on the mobile phone back cover 500.

[0055] Specifically, the CCD positioning mechanism first acquires a real-time image of the phone back cover 500 located at the printing station using a camera, and then analyzes the image to obtain the position and quantity information of the light leak points on the phone back cover 500. Subsequently, it transmits the position information of each light leak point to the first moving mechanism 310, enabling the print head 320 to accurately move to the vicinity of the light leak point to complete the printing operation. Alternatively, a control device can be connected to both the CCD positioning mechanism and the first moving mechanism 310. This control device receives the position and quantity information of the light leak points obtained by the CCD positioning mechanism and generates the movement path of the first moving mechanism 310 accordingly, allowing the first moving mechanism 310 to move the print head 320 to the vicinity of the light leak point more quickly, thus improving printing efficiency.

[0056] The CCD positioning mechanism accurately detects the position and number of light leakage points on the back cover 500 of the mobile phone and feeds this information back to the first moving mechanism 310. The first moving mechanism 310 then moves the printing head 320 accordingly, ensuring that the printing head 320 is always in the optimal printing position and angle, thereby improving the accuracy and efficiency of printing.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments, an ink cartridge 110 is provided on the base 100. The ink cartridge 110 is disposed on the base 100, and the top of the ink cartridge 110 is provided with an opening for recovering the remaining ink in the print head 320 before the printing equipment is turned off.

[0058] The size, dimensions, and shape of the ink cartridge 110 can be configured according to the size of the mobile phone back cover 500 and the printing device 300. For example, in this embodiment, the ink cartridge is conical, with the smaller diameter end facing the base 100 and the larger diameter end facing the printing device 300, allowing ink to converge along the inclined surface of the ink cartridge. During use, the first moving mechanism 310 moves the print head 320 to the vicinity of the opening of the ink cartridge 110 (usually above the opening), and then the print head 320 sprays ink into the ink cartridge 110, preventing ink from remaining in the print head 320 for extended periods and causing blockages. Furthermore, a return channel can be provided at the bottom of the ink cartridge 110 to transfer the ink in the ink cartridge 110 to other storage devices, such as a waste bin, improving recycling efficiency.

[0059] Furthermore, the ink collection box 110 can be placed below the printing station so that if ink splashes out when the printing device 300 is working, the splashed ink can be collected through the ink collection box 110 to prevent ink from contaminating the entire equipment, reduce the workload of the staff, and thus improve the overall work efficiency.

[0060] like Figures 2-5 As shown, in some embodiments, the feeding device 400 includes:

[0061] A baking mechanism 410 is set on a base 100 and is used to bake the back cover 500 of a mobile phone.

[0062] The second moving mechanism 420 is disposed on the base 100;

[0063] The suction cup component 430 is disposed in the second moving mechanism 420 and is used to pick up the mobile phone back cover 500 located at the unloading station.

[0064] The second moving mechanism 420 is used to: drive the suction cup component 430 to move to the unloading station when the conveying device 200 moves the mobile phone back cover 500 to the unloading station so that the suction cup component 430 picks up the mobile phone back cover 500, and drive the suction cup component 430 to move the mobile phone back cover 500 to the baking mechanism 410 so that the suction cup component 430 releases the mobile phone back cover 500 to the baking mechanism 410.

[0065] The baking mechanism 410 provides a high-temperature environment to heat the printed mobile phone back cover 500, thereby curing the ink onto the back cover 500. For example, the baking mechanism 410 can be a hot air circulating oven, including a chamber and a hot air circulation system consisting of a heating source and a fan disposed inside the chamber. The arrangement of the second moving mechanism 420 can refer to the aforementioned embodiments, and will not be repeated here.

[0066] The suction cup component 430 is used to pick up or release the back cover 500 of the mobile phone. It can be composed of a suction cup head and a vacuum pump. The vacuum pump is connected to the suction cup head through a pipe, so that the surface of the suction cup head generates negative pressure, thereby making the back cover 500 of the mobile phone tightly connected to the suction cup head.

[0067] In use, the conveying device 200 first moves the printed mobile phone back cover 500 to the unloading station. Then, the second moving mechanism 420 drives the suction cup component 430 to move above the mobile phone back cover 500 at the unloading station, so that the suction cup component 430 can grasp the mobile phone back cover 500 through vacuum adsorption. Subsequently, the second moving mechanism 420 drives the suction cup component 430 together with the mobile phone back cover 500 to the baking mechanism 410, and releases the mobile phone back cover 500 to the baking mechanism 410, so that the baking mechanism 410 heats the mobile phone back cover 500 to complete the curing of the ink on the mobile phone back cover 500.

[0068] In this embodiment, the transfer of the printed mobile phone back cover 500 is achieved by setting a second moving mechanism 420 and a suction cup component 430, and the ink on the mobile phone back cover 500 is quickly cured by a baking mechanism 410, which reduces the storage process and avoids the possibility of ink contamination during transportation, thereby improving the product yield.

[0069] like Figure 2 and Figure 4 As shown, in some embodiments, the baking mechanism 410 includes:

[0070] The conveying component 411 is disposed on the base 100 and includes a first end 411a and a second end 411b opposite to each other. The second moving mechanism 420 can drive the suction cup component 430 to reciprocate between the unloading station and the first end 411a. The first end 411a is used to receive the mobile phone back cover 500 on the suction cup component 430 so that the conveying component 411 conveys the mobile phone back cover 500 to the second end 411b to remove the mobile phone back cover 500.

[0071] The baking component 412 is disposed on the conveying component 411 and is used to bake the back cover 500 of the mobile phone.

[0072] The conveying component 411 can be used to transfer the phone back cover 500 to an external storage container or equipment in the next process, and can also bake the phone back cover 500 during transportation to improve work efficiency. It also has a storage function, allowing for the storage of some phone back covers 500. Specifically, the conveying component 411 can be a conveyor belt structure, with the phone back cover 500 placed on it for transport; or it can be a slide rail structure, with the phone back cover 500 placed on a slider that is slidably connected to the slide rail. A stepper motor or servo motor drives the slider to move along the slide rail, thereby moving the phone back cover 500 along the slide rail. Specific modifications and adjustments can be made according to actual needs, and this invention does not limit this. When the phone back cover 500 is moved to the second end 411b, it can be received manually or automatically to achieve storage. Preferably, a lifting plate 413 can be provided at the first end 411a of the conveying member 411, so that after the suction cup member 430 places the mobile phone back cover 500 on the plate 413, the plate 413 can tilt toward the first end 411a. The tilted plate 413 allows the mobile phone back cover 500 to slide toward the conveying member 411, so that the position where the suction cup member 430 releases the mobile phone back cover 500 can be set more freely, and at the same time, the automation level of the mobile phone back cover printing equipment is improved.

[0073] Furthermore, such as Figure 1As shown, if the mobile phone back cover 500 that needs to be printed is placed on the conveyor device 200 by manual or automatic means, that is, when a loading station needs to be set on the base 100, the second end 411b of the conveying component 411 can be set near the loading station, so that the loading and unloading operations can be completed at the same time, thus improving work efficiency.

[0074] The baking component 412 is a common heating component. For example, the baking component 412 can be an infrared lamp tube. By setting the infrared lamp tube along the conveying direction of the conveying component 411, the back cover 500 of the mobile phone is heated evenly during the movement, ensuring that its surface is uniformly cured.

[0075] In this embodiment, the printed mobile phone back cover 500 is first transferred to the first end 411a of the conveying member 411 by the second moving mechanism 420. Then, the conveying member 411 moves the mobile phone back cover 500 and transfers it to the second end 411b of the conveying mechanism while the baking member 412 heats it. This makes it easier for workers to remove the mobile phone back cover 500 and improves work efficiency.

[0076] In some embodiments, the baking mechanism 410 further includes a photoelectric sensor disposed at the first end 411a for detecting whether the back cover 500 of the mobile phone has reached the second end 411b.

[0077] A photoelectric sensor is used to detect whether the phone back cover 500 has reached the second end 411b of the conveying member 411, so as to accurately position the phone back cover 500 and prevent it from falling and causing damage if it is not removed in time after being conveyed to the second end 411b. Furthermore, the photoelectric sensor can communicate with the baking member 412. If the phone back cover 500 cannot be detected within a preset time, it can transmit information to the baking member 412 to shut it off, thereby saving energy and reducing the probability of safety accidents.

[0078] like Figure 3 As shown, in some embodiments, the mobile phone back cover printing equipment also includes an ink suction device 600, and an ink suction station is also provided on the base 100. The ink suction device 600 is disposed on the base 100 and is used to remove the ink sprayed from the printing device 300 onto the conveying device 200 when the conveying device 200 passes through the ink suction station.

[0079] During the printing process, the conveyor 200 is easily contaminated with ink, which can negatively affect other mobile phone back covers 500 placed on the conveyor 200. Therefore, an ink-absorbing device 600 is provided on the base 100 to absorb the ink on the conveyor 200. For example, the ink-absorbing device 600 can be a brush, which is driven by a motor to rotate and move on the conveyor 200, thereby cleaning the ink off the surface of the conveyor 200; the ink-absorbing device 600 can also be absorbent cotton, etc., and the present invention does not limit this.

[0080] By setting up an ink suction device 600 to remove ink residue on the conveying device 200, it prevents contamination of other mobile phone back covers 500 during subsequent printing processes, thereby improving printing quality. At the same time, it prevents ink from spreading to other locations along with the conveying device 200, maintaining a clean working environment.

[0081] like Figure 3 As shown, in some embodiments, the ink-absorbing device 600 includes an ink-absorbing assembly 620 and a third moving mechanism 610. The third moving mechanism 610 is disposed on the base 100, and the ink-absorbing assembly 620 is disposed on the third moving mechanism 610 for absorbing ink from the conveying device 200 under the drive of the third moving mechanism 610.

[0082] The third moving mechanism 610 can be configured in the same way as the first moving mechanism 310 in the aforementioned embodiment, and will not be described again here. The ink suction assembly 620 is used to absorb residual ink on the conveying device 200. For example, in this embodiment, a vacuum ink suction method is used. Several suction heads are provided on the third moving mechanism 610, and the suction heads are connected to a vacuum pump through pipes. By controlling the vacuum pump to generate negative pressure at the suction heads, the ink is absorbed. The third moving mechanism 610 can drive the suction heads to move, thereby absorbing ink at various positions of the conveying device 200, ensuring a cleaning effect, and thus improving the printing quality of other mobile phone back covers 500.

[0083] like Figure 6 As shown, in some embodiments, the conveying device 200 includes:

[0084] Rotary seat 210, which is rotatably connected to base 100;

[0085] Fixture 220 is disposed on rotating base 210 and can rotate with rotating base 210, and is used to support the back cover 500 of mobile phone;

[0086] The rotating power component is connected to the rotating base 210 for driving the rotating base 210 to rotate the fixture 220 through the printing station and the unloading station respectively.

[0087] The rotating base 210, through its rotational motion, moves the fixture 220 and the mobile phone back cover 500 placed on the fixture 220 sequentially to different workstations, including the printing workstation, the unloading workstation, and the ink absorption workstation, achieving seamless connection between each process and improving printing efficiency. Furthermore, by adjusting the radius of the rotating base 210 and the number of fixtures 220, the number and position of workstations on the production line can be flexibly configured to adapt to different production needs. For example, in this embodiment, the rotating base 210 is a disc, and the rotational power component is a DD motor (Direct Drive Motor), which is mounted on the base 100. The disc is positioned at the drive end of the DD motor, enabling the DD motor to drive the disc to rotate. Two parallel fixtures 220 are arranged on the disc at 90° intervals. Each fixture 220 can carry at least one mobile phone back cover 500. By rotating the disc, these fixtures 220 can be moved to different workstations to complete different operations.

[0088] Compared to linear conveying devices 200 such as conveyor belts, the rotating structure design of the rotary seat 210 allows the workstations to be arranged more closely, greatly saving the space occupied by the mobile phone back cover printing equipment and making installation easier; and by adjusting the radius of the rotary seat 210 and the number of fixtures 220, the number and position of the workstations can be flexibly configured to meet different production needs.
