Description

Technical Field

[0001] This invention relates to the technical field of laser printing. More specifically, this invention relates to a laser printer for DIY mobile phone cases. Background Technology

[0002] Laser printing technology utilizes a high-energy-density, highly directional, and monochromatic laser beam to precisely irradiate the surface of a material. Under the influence of the laser, localized areas of the material rapidly absorb energy, undergoing melting, vaporization, or changes in chemical structure. This allows for precise etching or surface property control, ultimately forming the desired text and patterns.

[0003] Currently, some commercial districts have set up self-service laser printers for DIY phone cases. Users can install their own phone cases on the machine's fixtures and customize their designs or text on-site. However, the laser processing generates a lot of heat, and most phone case raw materials do not contain laser-sensitive additives. This requires the use of a higher-power laser beam for processing, which can cause some phone case materials with poor heat resistance to warp or deform when heated. In severe cases, this can even damage the phone case, rendering it unusable and seriously affecting the user experience.

[0004] If air cooling is used, the cooling airflow may agitate dust or impurities accumulated inside the equipment, causing them to pass through the laser beam path, interfering with laser focusing and scanning, and affecting printing accuracy and quality. To solve the heat dissipation problem, existing technologies attempt to integrate cooling structures inside the fixture to conduct heat and cool the phone case through direct contact. However, due to the variety of phone cases brought by users, it is difficult for the fixture to achieve a full fit with all phone cases. As a result, the cooling structure can only act on local areas, especially at edges or in complex areas where heat dissipation capacity is insufficient, and there is still a risk of thermal deformation.

[0005] In summary, this application proposes a laser printer for DIY mobile phone cases, which improves the aforementioned technical problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: A laser printer for DIY mobile phone cases, such as... Figures 1-4 As shown, it includes a first outer shell 1, a second outer shell 2, and a control panel 3; the second outer shell 2 is bolted to the first outer shell 1; the control panel 3 is bolted to the second outer shell 2; it also includes a housing 4, an automatic laser head 5, a connecting block 6, an electric push rod 7, a side plate 8, an L-shaped plate 9, a semiconductor cooling chip 10, a heat-conducting plate 11, a drive assembly, and a conveying assembly; the housing 4 is slidably connected inside the first outer shell 1; the automatic laser head 5 is installed inside the second outer shell 2; the connecting block 6 is bolted to the housing 4; four electric push rods 7 are fixedly connected to the connecting block 6; each electric push rod 7 has a side plate 8 fixedly connected to its telescopic end, and the side plate 8 contacts the side of the connecting block 6; the four... An L-shaped plate 9 is provided at each corner, and the L-shaped plate 9 is slidably connected to the corresponding side plate 8; both the side plate 8 and the L-shaped plate 9 are in contact with the box body 4; a semiconductor cooling chip 10 is fixedly connected to the connecting block 1 6, and the semiconductor cooling chip 10 is in contact with the side plate 8 and the L-shaped plate 9; a heat-conducting plate 11 is fixedly connected to the semiconductor cooling chip 10, and the heat-conducting plate 11 is in contact with the side plate 8 and the L-shaped plate 9; a driving assembly is connected to the outer shell 2; a conveying assembly is connected to the connecting block 1 6; a cavity 91 is formed between the connecting block 1 6 and the semiconductor cooling chip 10; six grooves 92 are opened on the connecting block 1 6, and the grooves 92 communicate with the cavity 91.

[0022] The drive assembly includes a motor 201, a lead screw 202, and a connecting block 203; the motor 201 is bolted to the outer casing 2; the lead screw 202 is rotatably connected to the outer casing 2, and the lead screw 202 is fixedly connected to the output end of the motor 201; the connecting block 203 is fixedly connected to the box 4, and the connecting block 203 is spun to the lead screw 202.

[0023] The conveying assembly includes an electric push rod 204 and a piston plate 205; the electric push rod 204 is bolted to the connecting block 6; the piston plate 205 is fixedly connected to the telescopic end of the electric push rod 204, and the piston plate 205 slides in the cavity 91.

[0024] A sealing ring is provided on the outer side of the piston plate 205 to improve the sealing performance.

[0025] First, the user prints a pattern or text using the control screen 3. Then, the user controls the motor 201 to start via the control screen 3. The motor 201 drives the lead screw 202 to rotate, which in turn drives the connecting block 203 to move forward. The connecting block 203 then drives the housing 4 and its components forward, moving the connecting block 6 to the outside of the outer casing 1. Next, the user places the phone case, opening downwards, onto the outside of the assembly formed by the connecting block 6, the electric push rod 7, the side plate 8, the L-shaped plate 9, the semiconductor cooling chip 10, and the heat-conducting plate 11, placing the phone case on the heat-conducting plate 11. At this point, the upper side of the heat-conducting plate 11 contacts the top of the inner side of the phone case. Then, the user controls the housing 4 and its components to move back to their original positions via the motor 201, moving the phone case to the inside of the housing 4. Push rod 7 controls the four side plates 8 to move in opposite directions, so that the four side plates 8 simultaneously abut against and press against the inner wall of the phone case, thereby tightening and fixing the phone case from the inside. During this process, the side plates 8 can also correct the position of the phone case and push it to the middle of the connecting block 6 to complete the clamping and positioning operation for phones of different sizes. Then, the automatic laser head 5 performs laser printing on the upper side of the phone case. After printing is completed, the electric push rod 7 drives the side plates 8 to move back to their original position, so that the side plates 8 stop fixing the phone case. Then, the motor 201 controls the box 4 and its parts to move forward, thereby moving the printed phone case to the outside of the outer shell 1. After it is manually removed, the motor 201 controls the box 4 and its parts to move back to their original position, completing the DIY phone case printing operation.

[0026] When this laser printer is powered on, the thermoelectric cooler 10 begins its cooling operation, cooling the heat-conducting plate 11 and the air inside the cavity 91. The thermoelectric cooler 10 is equipped with a temperature control module, which can control the heat-conducting plate 11 and the air inside the cavity 91 to maintain a relatively low temperature. Figure 4As shown, during the expansion of the side panel 8 to tighten and fix the phone case, the L-shaped plate 9 will slide adaptively with the side panel 8, thereby causing the side panel 8 and the L-shaped plate 9 to expand together. At this time, a U-shaped space is formed between the box body 4, connecting block 6, side panel 8, L-shaped plate 9, heat-conducting plate 11 and phone case. Then, the electric push rod 204 drives the piston plate 205 to move upward, causing the piston plate 205 to squeeze the air in the cavity 91 from the groove 92 into the U-shaped space and contact the outer edge of the phone case. At this time, the heat-conducting plate 11 cools the middle of the phone case, and the cold air cools the outer edge of the phone case, thereby achieving sufficient cooling of various parts of the phone case of different sizes. Subsequently, Laser printing on the phone case effectively avoids deformation caused by overheating. It's important to note that a single laser printing operation can be completed within five seconds, and the cool air remaining in the U-shaped space is sufficient to cool the outer edge of the phone case. During use, the side plate 8, used to fix the phone case, also works with the L-shaped plate 9 to form a U-shaped space on the lower side of the outer edge of the phone case. The piston plate 205 delivers pre-cooled air from the cavity 91 to the U-shaped space to cool the outer edge of the phone case, while the heat-conducting plate 11 cools the middle of the phone case. This ensures sufficient cooling of all parts of the phone case of different sizes, preventing deformation caused by insufficient cooling of the outer edge.

[0027] Example 2, based on Example 1, such as Figures 4-6 As shown, it also includes a covering assembly, which includes a first baffle 206 and a second baffle 207; a first baffle 206 is fixedly attached to each of the two rear L-shaped plates 9, and the first baffle 206 contacts the heat-conducting plate 11; a second baffle 207 is fixedly attached to the rear side plate 8; the heat-conducting plate 11 contacts the second baffle 207; the first baffle 206 contacts the second baffle 207; a second groove 93 is formed on the heat-conducting plate 11 corresponding to the position of the first baffle 206.

[0028] The semiconductor cooling chip 10 and the heat-conducting plate 11 are both provided with a through hole 94. The through hole 94 is connected to the cavity 91 and the second groove 93. Air in the cavity 91 can be discharged into the second groove 93 through the through hole 94.

[0029] An infrared sensor is installed on the outer shell 1. When the infrared sensor detects that the user's limb is in the movement path of the box 4, the box 4 cannot move to avoid pinching injury.

[0030] An alarm is installed on the outer casing 1, which can sound an alarm in case of malfunction and remind the user to stop using the device.

[0031] Both outer casing 1 and outer casing 2 are coated with an anti-corrosion layer, which helps to improve their lifespan.

[0032] The contact surfaces of the outer shell 2 and the box 4 are both designed to be smooth, which can reduce friction and thus reduce wear.

[0033] The phone case has a camera hole. When the camera hole is aligned with the U-shaped space, a large amount of cold air inside will leak out from the camera hole, interfering with the cooling operation. Therefore, a baffle 206 is set on each of the two L-shaped plates 9 at the rear, and a baffle 207 is set on the side plate 8 at the rear. When the phone case is manually placed on the outside of the connecting block 6, with the end of the phone case with the camera hole facing backward, and the phone case is fixed by the side plate 8, the side plate 8 at the rear moves the two L-shaped plates 9, baffle 206 and baffle 207 at the rear backward. Then the left and right side plates 8 move in opposite directions, and the side plates 8 move the two baffles 206 in opposite directions, thereby unfolding the baffles 206 and baffle 207. At this time, the baffles 206 and baffle 207 are in the following state. Figure 6 As shown, in this way, the first baffle 206 and the second baffle 207 cover the camera hole on the phone case to prevent a large amount of cold air from flowing out of the camera hole and affecting the cooling.

[0034] During the cooling process of the semiconductor cooling chip 10, the baffle 206 is also cooled. After the phone case is clamped, the lower side of the phone case contacts the baffle 206, at which point the baffle 206 can cool the phone case. Figure 6 As shown, after the first baffle 206 and the second baffle 207 are unfolded, a second groove 93 is formed on the heat-conducting plate 11. At this time, the position of the phone case corresponding to the second groove 93 does not contact the heat-conducting plate 11 or the first baffle 206. Furthermore, the air flow inside the narrow second groove 93 is poor, making it difficult for the cold air in the U-shaped space to flow into the second groove 93. This results in a low cooling effect at the position of the phone case corresponding to the second groove 93. Therefore, through holes 94 are opened on the semiconductor cooling chip 10 and the heat-conducting plate 11, and the piston plate 205 pushes the cavity 9. When the air moves within the device, some air flows through the through hole 94 into the groove 93, forming a flow of cold air within the groove 93, which cools the corresponding area of ​​the phone case. In use, by opening the through hole 94 on the semiconductor cooling chip 10 and the heat-conducting plate 11, the piston plate 205 can push some cold air through the through hole 94 into the groove 93 to cool the phone case, thus avoiding the problem of reduced cooling effect in local areas of the phone case due to the installation of the deployable baffle 206 and baffle 207.
