Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a printer housing and a 3D printing device. Background Technology

[0002] Since recessed photopolymer 3D printers are often used to print extremely precise parts, in order to reduce the impact of machine vibration on accuracy, the printer needs to be designed to be very robust and have good rigidity to suppress machine vibration.

[0004] However, this approach adopted by existing products usually results in an excessively heavy casing, increasing production and transportation costs, and causing inconvenience for users during installation, failing to simultaneously achieve both lightweight design and good protection. Utility Model Content

[0041] This utility model proposes a printer housing. It aims to solve the problems of existing products leading to excessive weight, increased production and transportation costs, inconvenience for users during installation, and the inability to simultaneously achieve lightweight design and good protection.

[0042] Please see Figure 1In one embodiment of this utility model, the printer housing 100 is applied to a 3D printer. The printer housing 100 includes two side plates 1, a back plate 2, four support columns 3, a bottom plate 4, and a top plate 5. The two side plates 1 are spaced apart laterally and extend longitudinally. The back plate 2 is disposed between the two side plates 1 and extends laterally. The four support columns 3 are arranged in an array in both the lateral and longitudinal directions and extend vertically. Two of the support columns 3 are used to connect the back plate 2 laterally. The two ends are connected to one end of the two side plates 1 in the longitudinal direction, and the other two support columns 3 are used to connect to the other ends of the two side plates 1 in the longitudinal direction respectively. The bottom plate 4 is connected to the lower end of the four support columns 3, and the top plate 5 is connected to the upper end of the four support columns 3. The two side plates 1, the back plate 2, the bottom plate 4 and the top plate 5 are used to enclose and form a receiving cavity. One end of the receiving cavity in the longitudinal direction is open. The receiving cavity is used to accommodate the 3D printer, and its open end is used for the operator to pick up and put in materials.

[0043] In this invention, the printer housing 100 directly supports the 3D printer, placing it within the accommodating cavity to reduce the impact of the external environment on its operation. The back plate 2 supports the 3D printer's drive mechanism. Since the back plate 2 has two support columns 3 connected to its two ends in the horizontal direction, adjacent support columns 3 provide support to the back plate 2, ensuring its vertical support of the 3D printer's drive mechanism. The two side plates 1 further enhance the printer housing 100's load-bearing capacity. The printer housing 100 also includes a top plate 5 and a bottom plate 4, which are respectively connected to… The top plate 5 and the bottom plate 4 are connected to the upper and lower ends of the four support columns 3, thus limiting the tilting of the four support columns 3 in the lateral or longitudinal direction. This restricts the position of the two side plates 1 and the bottom plate 4 in the lateral and longitudinal directions, ensuring the support performance of the printer housing 100 for the 3D printer and ensuring the rigidity of the printer housing 100. Furthermore, the printer housing 100 reduces the frame structure, directly providing support through the housing, reducing the weight of the machine body and achieving a lightweight design. At the same time, since the drive mechanism of the 3D printer is supported by the side plates 1, the printer housing 100 can also provide good shock absorption performance for the 3D printer, so that the 3D printer remains stable under the influence of external forces and vibrations, thereby improving the printing accuracy of the 3D printer.

[0044] It is understood that in this embodiment, the number of the support columns 3 is set to four, and at this time, the printer housing 100 is a square cube structure.

[0045] In another embodiment of this utility model, five support columns 3 are provided, spaced apart in the horizontal or vertical direction. Correspondingly, three side plates 1 are provided, located on both sides of the back plate 2 in the horizontal direction. One side plate 1 is provided on one side of the back plate 2 in the horizontal direction, and two side plates 1 are provided on the other side. In this arrangement, each side plate 1 is connected to two support columns 3 at both ends, thereby forming the accommodating cavity together with the back plate 2, the top plate 5, and the bottom plate 4.

[0046] Of course, in other embodiments of this utility model, the number of support columns 3 and side plates 1 can also be set to other quantities. Specifically, it is only necessary to ensure that the number of side plates 1 is two less than the number of support columns 3. In actual setting, it can be selected according to the needs, and this utility model does not limit it.

[0047] It should be noted that, since the top plate 5 is connected to the four support columns 3 simultaneously, it prevents the upper ends of the four support columns 3 from tilting laterally or longitudinally, thereby ensuring the stability of the accommodating cavity. To ensure the ability of the top plate 5 to limit the tilt of the four support columns 3, the top plate 5 is fixedly connected to the upper ends of the four support columns 3. Of course, this utility model does not limit the specific connection form between the top plate 5 and the four support columns 3. In one embodiment of this utility model, the top plate 5 is provided with a plurality of first through holes in the vertical direction, and the plurality of first through holes are respectively provided for the four support columns 3. The upper ends of the four support columns 3 protrude to form a plurality of pins, and each pin is inserted into one of the first through holes. In this way, the connection stability between the top plate 5 and the four support columns 3 is ensured.

[0048] In another embodiment of this utility model, the top plate 5 is provided with a plurality of first through holes along the vertical direction, and the plurality of first through holes are respectively provided for the four support columns 3 and are threadedly connected to the upper end of the corresponding support column 3. This arrangement can also ensure the connection stability between the top plate 5 and the four support columns 3.

[0049] Of course, when the top plate 5 is threadedly connected to the four support columns 3, this utility model does not limit the specific threaded connection form of the top plate 5 and the four support columns 3. In another embodiment of this utility model, the printer housing 100 also includes a plurality of connecting bolts. The upper ends of the four support columns 3 are recessed with threaded grooves corresponding to the plurality of first through holes. Each connecting bolt passes through the corresponding first through hole to extend into the corresponding threaded groove, thereby engaging with the threaded groove.

[0050] In another embodiment of this utility model, the upper ends of the four support columns 3 are provided to protrude from the multiple first through holes to form threaded protrusions. The multiple first through holes are all configured as threaded holes. With this configuration, each threaded protrusion can extend into the corresponding first through hole to engage with the threaded first through hole, thereby achieving a stable connection between the top plate 5 and the four support columns 3.

[0051] It should also be noted that the present invention does not limit the specific number of the first through holes. In one embodiment of the present invention, the number of the first through holes is set to four, and the four first through holes correspond to the four support columns 3 respectively. In another embodiment of the present invention, the number of the first through holes is set to eight, and in this case, every two first through holes correspond to one support column 3. In other embodiments of the present invention, the number of the first through holes can also be set to other numbers. In order to ensure the stability of the top plate 5 under stress, it is only necessary to ensure that the number of the first through holes is a multiple of 4. In actual setting, it can be selected according to the needs.

[0052] Similarly, since the base plate 4 is connected to the lower ends of the four support columns 3 simultaneously to prevent the lower ends of the four support columns 3 from tilting in the horizontal or vertical direction, thereby ensuring the stability of the accommodating cavity, in order to ensure the tilt-limiting ability of the base plate 4 on the four support columns 3, the base plate 4 should be fixedly connected to the lower ends of the four support columns 3. Of course, this utility model does not limit the specific connection form between the base plate 4 and the four support columns 3. In one embodiment of this utility model, the base plate 4 and the four support columns 3 can be fixedly connected by a pin connection; in another embodiment of this utility model, the base plate 4 and the four support columns 3 can be connected by a threaded connection; and in other embodiments of this utility model, the base plate 4 and the four support columns 3 can also be connected by welding, bonding or other connection methods. In actual installation, the appropriate method can be selected according to the requirements.

[0053] In this utility model, the base plate 4 is threadedly connected to the four support columns 3.

[0054] Specifically, the base plate 4 has a plurality of second through holes extending vertically, each of which corresponds to one of the four support columns 3 and is threadedly connected to the lower end of the corresponding support column 3. Of course, this invention does not limit the specific threaded connection between the base plate 4 and the four support columns 3. In another embodiment of this invention, the printer housing 100 further includes a plurality of connecting bolts. The lower ends of the four support columns 3 are recessed with threaded grooves corresponding to the plurality of second through holes. Each connecting bolt passes through the corresponding second through hole and extends into the corresponding threaded groove, thereby engaging with the threaded groove.

[0055] In another embodiment of the present invention, the lower ends of the four support columns 3 are provided to protrude from the multiple second through holes to form threaded protrusions. The multiple second through holes are all configured as threaded holes. With this configuration, each threaded protrusion can extend into the corresponding second through hole to engage with the threaded second through hole, thereby achieving a stable connection between the base plate 4 and the four support columns 3.

[0056] Meanwhile, this utility model does not limit the number of the second through holes. In this utility model, the number of the second through holes can be set to four, eight, twelve or other numbers, as long as the stress on the base plate 4 is stable, so that the number of the second through holes is a multiple of 4.

[0057] Furthermore, the two side plates 1 also ensure the stability of the printer housing 100 in the circumferential direction. To ensure the connection stability between the two side plates 1 and the support columns 3, in one embodiment of this invention, each side plate 1 is provided with a plurality of third through holes in the transverse direction. These third through holes are respectively provided for the two support columns 3 and are threadedly connected to the side ends of the corresponding support columns 3. This ensures the connection stability between each side plate 1 and the corresponding two support columns 3.

[0058] Similarly, the back plate 2 also ensures the stability of the printer housing 100 in the circumferential direction. In one embodiment of this utility model, the back plate 2 is provided with a plurality of fourth through holes in the longitudinal direction. The plurality of fourth through holes are respectively provided for two of the support columns 3 and are threadedly connected to the side end of the corresponding support column 3. In this way, the connection stability between the back plate 2 and the corresponding two support columns 3 can be ensured, thereby improving the stability of the printer housing 100.

[0059] It is understood that this utility model does not limit the specific screw connection form between each of the side plates 1 and the back plate 2 and the corresponding two support columns 3. Each of the side plates 1 and the back plate 2 can be connected to the side ends of the corresponding two support columns 3 by means of connecting bolts passing through the third through hole or the fourth through hole; or the side ends of the corresponding two support columns 3 can be made to protrude to form a threaded connection protrusion, thereby connecting the third through hole or the fourth through hole.

[0060] Of course, this utility model does not limit the number of the third through hole and the fourth through hole. In this utility model, the number of the third through hole and the fourth through hole can be set to two, four, six, eight or other numbers, as long as the stress on each of the side plates 1 and the back plate 2 is stable, so that the number of the third through hole and the fourth through hole is set to an even number.

[0061] Furthermore, to facilitate operation of the 3D printer within the cavity, in one embodiment of this invention, the printer housing 100 further includes a panel 6. The panel 6 is longitudinally spaced from the back plate 2 and connected to two additional support columns 3 at its two ends in the transverse direction. The panel 6 has a through-hole 61 extending longitudinally, which accommodates a touchscreen or buttons. With this configuration, when the operator approaches the open end of the printer housing 100, the operator can directly operate the touchscreen or buttons within the through-hole 61, thereby controlling the 3D printer within the cavity. Simultaneously, it facilitates the operator loading material into the cavity from the open end before printing begins and allows for easy removal of material from the cavity through the open end after printing.

[0062] It should be noted that in this utility model, the panel 6 only covers part of the open end of the receiving cavity, so as to ensure that the operator can smoothly put materials into the receiving cavity from the open end or take materials out of the receiving cavity.

[0063] In this invention, it should also be noted that since the 3D printer also has a driver, which requires a large installation space, in one embodiment of this invention, to ensure sufficient installation space for the driver, the back plate 2 has a longitudinally extending mounting hole for mounting the driver. With this arrangement, the driver portion of the 3D printer is located outside the printer housing 100, while the other portion can connect to the portion of the 3D printer within the receiving cavity via the mounting hole, thereby driving the portion within the receiving cavity to perform printing operations. This arrangement provides installation space for the driver while ensuring the normal operation of the 3D printer.

[0064] Furthermore, in one embodiment of this invention, to prevent the sharp edges of the printer housing 100 from scratching the operator when operating the 3D printer housed within the receiving cavity of the printer housing 100, each of the support columns 3 has multiple end faces in the circumferential direction. Among these end faces, adjacent two end faces form an included angle, which is rounded. This rounded corner design protects the operator from scratches by the printer housing 100 and also improves the aesthetics of the printer housing 100.

[0065] To ensure the load-bearing capacity of the printer housing 100 and to improve the structural strength of the multiple structures within the printer housing 100, in this invention, the material of each side plate 1 includes at least one of aluminum alloy, steel, and plastic. For example, in one embodiment of this invention, the material of each side plate 1 is aluminum alloy, thus the side plate 1 has excellent structural strength and load-bearing capacity. In another embodiment of this invention, the material of each side plate 1 can also be steel, and the use of steel side plates 1 can also ensure the load-bearing capacity of the printer housing 100.

[0066] Similarly, in this invention, the structural strength of the printer housing 100 can be improved by providing the structural strength of the back plate 2. In this invention, the material of the back plate 2 includes at least one of aluminum alloy, steel, and plastic.

[0067] Of course, the structural strength of the panel 6 can also be improved. In this utility model, the material of the panel 6 includes at least one of aluminum alloy, steel and plastic.

[0068] Furthermore, to further enhance the restraining ability of the top plate 5 on the four support columns 3, thereby improving the stability of the printer housing 100, in this invention, the material of the top plate 5 includes at least one of aluminum alloy, steel, and plastic. For example, in one embodiment of this invention, the material of the top plate 5 can be set as aluminum alloy; in another embodiment, the material of the top plate 5 can be set as steel; and in yet another embodiment, the material of the panel 6 can also be set as plastic. Specifically, in actual installation, the material can be selected according to requirements.

[0069] Similarly, in order to improve the ability of the base plate 4 to restrict the four support columns 3, thereby improving the stability of the printer housing 100, in this utility model, the material of the base plate 4 includes at least one of aluminum alloy, steel and plastic.

[0070] Of course, in order to limit the weight of the printer while ensuring the structural strength and stability of the printer housing 100 for ease of transportation and use, in one embodiment of this utility model, the thickness of the side plate 1 is A, 0.8mm≤A≤3.2mm. Thus, by limiting the thickness of the side plate 1, the structural strength of the side plate 1 is ensured while limiting its weight, thereby ensuring the stability of the printer housing 100 and achieving its lightweight design.

[0071] Similarly, the stability and lightweight of the printer housing 100 can be achieved simultaneously by limiting the thickness of the back plate 2. In another embodiment of the present invention, the thickness of the back plate 2 is B, where 0.8mm≤B≤3.2mm.

[0072] It is understood that the stability and lightweight of the printer housing 100 can also be achieved by limiting the thickness of the top plate 5. In another embodiment of the present invention, the thickness of the top plate 5 is C, where 0.8mm≤C≤3.2mm.

[0073] Of course, by limiting the thickness of the base plate 4, the stability and lightweight characteristics of the printer housing 100 can also be achieved simultaneously. In another embodiment of this utility model, the thickness of the base plate 4 is D, 0.8mm≤D≤3.2mm.

[0074] Furthermore, in this utility model, the printer housing 100 also includes the panel 6. Therefore, the thickness of the panel 6 can also be limited. In one embodiment of this utility model, the thickness of the panel 6 is E, where 0.8mm≤E≤3.2mm.

[0075] Of course, other forms can be adopted to ensure the load-bearing capacity of the printer housing 100. For example, in one embodiment of this utility model, the printer housing 100 further includes multiple reinforcing rods, each of which extends vertically and is inclined in the longitudinal or transverse direction. The two ends of each reinforcing rod are respectively connected to the upper end of a support column 3 and the lower end of an adjacent support column 3. With this arrangement, the addition of each reinforcing rod increases the force transmission path to distribute the pressure on the support column 3. At the same time, the addition of the reinforcing rod can further improve the stability of the support column 3, thereby ensuring the load-bearing capacity of the printer housing 100.

[0076] This utility model also proposes a 3D printing device, which includes the printer housing 100 described above, and a 3D printer disposed within the printer housing 100. The specific structure of the printer housing 100 is as described in the above embodiments. Since this 3D printing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0077] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
