Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology, and in particular to an ultrathin laser and additive manufacturing equipment. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology that uses slicing software to plan the path of a three-dimensional digital model and then uses materials such as powder, filament, or liquid to build up a three-dimensional solid model layer by layer. Compared with traditional processing methods, 3D printing technology has the advantages of not requiring molds, high material utilization, short product realization cycle, and the ability to create high-performance, complex structural parts without molds, quickly, and with full density, gradually becoming the best technical approach to address technological challenges in many fields. In recent years, 3D printing applications have gradually expanded from industrial applications to consumer products. Faced with the huge demand for consumer products, traditional single-channel printing cannot meet the needs, requiring the development of multi-channel printing equipment. This necessitates the integration of the laser, the core material of the printing equipment, to address the problem of the excessively large overall size of the existing ultra-thick laser in multi-channel printing equipment.

[0037] This invention provides an ultrathin laser, characterized by comprising a chassis 1, a water-cooled plate 2, a cover plate 3, a pump source 5, an optical fiber 6, a control board 7, a drive board 8, a drive power supply 9, and a control board power supply 10. The chassis 1 includes a first mounting cavity 13 and a second mounting cavity 11, spaced apart. The drive power supply 9 and the control board power supply 10 are installed in the first mounting cavity 13. The water-cooled plate 2 is installed in the second mounting cavity 11 and fixedly connected to the chassis 1. The pump source 5, optical fiber 6, control board 7, and drive board 8 are installed on the water-cooled plate 2 in the second mounting cavity 11. The cover plate 3 is detachably connected to the chassis 1. The pump source 5, optical fiber 6, control board 7, drive board 8, drive power supply 9, and control board power supply 10 are arranged in a single plane, reducing the space occupied by the chassis 1 in the height direction. Furthermore, the ultrathin structure of each module further reduces the overall thickness of the ultrathin laser, solving the problem of excessively large overall equipment caused by existing ultrathin lasers in multi-channel printing devices.

[0038] As an optional implementation, the chassis 1 includes four side plates and a bottom plate; the four side plates and the bottom plate together form an opening, and a cover plate 3 is placed over the opening. A first partition plate 12 is provided between the first mounting cavity 13 and the second mounting cavity 11. The lower end of the first partition plate 12 is fixedly connected to the bottom plate of the chassis 1, and the upper end of the first partition plate 12 is in sealing contact with the cover plate 3.

[0039] A first partition plate 12 is provided between the first mounting cavity 13 and the second mounting cavity 11. The lower end of the first partition plate 12 is sealed to the bottom of the chassis 1, and the upper end of the first partition plate 12 is sealed to the cover plate 3, so that the first mounting cavity 13 and the second mounting cavity 11 are closed, isolating the power module from the optical module and the power module from the circuit module, so as not to affect the sealing and anti-condensation design, and also to ensure the separation of strong and weak.

[0040] The first partition plate 12 is made of a non-thermal-conducting material, which prevents heat transfer between the first mounting cavity 13 and the second mounting cavity 11. The length direction of the first partition plate 12 is consistent with the length direction of the chassis 1, and the position of the first partition plate 12 is closer to the right side panel of the chassis 1. The space of the second mounting cavity 11 is larger than the space of the first mounting cavity 13.

[0041] The chassis 1 includes four side panels and a bottom plate. After the four side panels and the bottom plate are closed, an opening will be left. This opening is covered by a cover plate 3 to protect the internal components from external influences.

[0042] As an optional implementation, the chassis 1 is fully welded, and at least one gap in the chassis 1 is sealed with sealant. It is not necessary to seal individual panels on the chassis 1, which further simplifies the chassis structure and ensures the airtightness of the chassis 1.

[0043] As an optional implementation, the four side plates, the bottom plate, and the cover plate 3 are all detachably connected. This allows for easy disassembly or replacement of any components inside the laser when they malfunction, significantly improving its maintainability.

[0044] As an optional implementation, the four side plates are fixedly connected to form a mounting bracket, which is detachably connected to the base plate and the cover plate 3, thereby improving the airtightness of the chassis 1 and the maintainability of the chassis 1.

[0045] As an optional implementation, the left and right ends of the first partition plate 12 are fixedly connected to the front and rear end plates of the chassis 1, respectively.

[0046] As an optional implementation, the water-cooled plate 2 adopts an embedded pipe design, thereby reducing the thickness of the water-cooled plate 2. The water-cooled plate 2 includes a substrate 24 and an embedded pipe 21. The embedded pipe 21 is embedded in the substrate 24. The embedded pipe 21 has a meandering structure and is concentrated below the pump source 5, optical fiber 6, control board 7 and drive board 8. This is to dissipate heat for the optical module and circuit module. The embedded pipe 21 uses a 10mm diameter copper tube with a thermal conductivity of 390W (mk). The pipe layout is combined with the actual processing limits and heat dissipation requirements.

[0047] The two ends of the embedded pipe 21 are respectively connected to an inlet connector 22 and an outlet connector 23. The inlet connector 22 and the outlet connector 23 are both connected to the same side wall of the casing 1. The inlet connector 22 and the outlet connector 23 are located at the rear end of the casing 1.

[0048] As an optional implementation, such as Figure 3 As shown, the embedded pipeline 21 includes a first meandering section 211, a second meandering section 212, and a straight section 213. The water inlet connector 22, the first meandering section 211, the second meandering section 212, the straight section 213, and the water outlet connector 23 are connected in sequence. The first meandering section 211 is located in the rear half of the second mounting cavity 11, the second meandering section 212 is located in the front half of the second mounting cavity 11, and the straight section 213 is located in the left side of the second mounting cavity 11.

[0049] The first meandering section 211 and the second meandering section 212 have an S-shaped structure. The first meandering section 211 is set in a straight line, that is, the overall flow direction of the water is from right to left. The second meandering section 212 is set in a vertical line, that is, the overall flow direction of the water is from back to front.

[0050] As an optional implementation, the optical module includes a pump source 5, which is installed in the front half of the second mounting cavity 11 and corresponds to the second meandering portion 212.

[0051] There are multiple pump sources 5, each having a tail and a head. The heads of adjacent pump sources face different sides. All pump sources 5 are distributed in a crisscross pattern from front to back. The heads of the pump sources 5 on the left face right, and the heads of the pump sources 5 on the right face left. Each pump source 5 corresponds to at least two pipes on the second meandering section 212, ensuring that the pump sources 5 are arranged compactly while ensuring heat dissipation.

[0052] As an optional implementation, a fiber optic groove is provided in the middle region of the substrate 24, and the optical fiber 6 is placed in the fiber optic groove so that the optical fiber 6 does not occupy height space. The optical fiber 6 is located in the rear left side region of the second mounting cavity 11, and the optical fiber 6 corresponds to the first meandering part 211 and the straight part 213 to ensure heat dissipation of the optical fiber.

[0053] As an optional implementation, the control board 7 is installed in the rear side region of the second mounting cavity 11, and the drive board 8 is installed in the right rear region of the second mounting cavity 11, with the control board 7 and the drive board 8 forming an L-shaped structure.

[0054] As an optional implementation, the control board 7 and the drive board 8 are installed in the rear side area of ​​the second mounting cavity 11, and the control board 7 and the drive board 8 form a straight line structure.

[0055] As an optional implementation, the control board 7 and the drive board 8 are installed in the right side region of the second mounting cavity 11, and the control board 7 and the drive board 8 form a straight line structure.

[0056] As an optional implementation, the drive power supply 9 is installed in the front half of the first mounting cavity 13, and the control board power supply 10 is installed in the rear half of the first mounting cavity 13. The drive power supply 9 is an ultra-thin power supply with a thickness of 41±1mm.

[0057] As an optional implementation, the front end of the chassis 1 is provided with an indicator light panel 4, a handle 14 and a push-button switch 15.

[0058] As an optional implementation, a sealing ring is provided between the chassis 1 and the cover plate 3 to further reduce the thickness of the chassis 1 while ensuring the sealing of the chassis. The sealing ring can be selected from EPDM with a compression of 50-70% or other commonly used sealing ring materials.

[0059] As an optional implementation, the overall thickness of the ultrathin laser is 44±1mm, and the overall design meets the 1U thickness standard and complies with EU safety regulations.
