Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a 3D printing substrate. Background Technology

[0002] The heated bed, installed above the leveling assembly of a 3D printer, has an upper plate on its top surface that directly contacts the printed part. To facilitate cleaning the plate or removing the printed part from the upper plate, the upper plate is usually detachable from the heated bed and can be removed directly from the printer's loading / unloading window. However, to prevent the upper plate from shifting during printing and affecting print quality, the heated bed and upper plate are typically magnetically secured. A soft magnetic sheet is attached to the top surface of the heated bed to attract the ferromagnetic upper plate, thus limiting their relative displacement during printing and facilitating the loading / unloading of the upper plate. Due to the different characteristics of printing consumables and printing needs, the materials used for the upper plate are also diverse. Some upper plates, such as carbon lattice glass, which are not ferromagnetic, can only be fixed by clamps. When picking up and putting down, the clamps need to be operated to loosen or tighten the plate, which is inconvenient.

[0003] To address the problems existing in the prior art, this utility model designs and manufactures a 3D printed base plate to overcome the aforementioned defects. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a 3D-printed base plate that enables rapid assembly and disassembly of the upper plate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a 3D printed base plate, including a heated bed platform and an upper plate, wherein the heated bed platform includes a support plate and a heating pad, and the upper surface of the support plate is provided with a placement groove, and the heating pad is placed in the placement groove; The support plate has two limiting grooves on both sides. The upper plate has two inserts on each side that correspond to the limiting grooves. One end of each insert has a horizontal groove. The insert is inserted into the upper plate through the horizontal groove. The end of the insert with the horizontal groove can abut against the end of the limiting groove away from the side of the support plate.

[0006] Preferably, the limiting groove is a V-shaped groove, and the lower end face of the insert is a contoured surface that can match the limiting groove.

[0007] Preferably, the end of the limiting groove near the side of the support plate is not closed.

[0008] Preferably, an anti-slip pad is provided on the upper surface of the transverse groove.

[0009] Preferably, the anti-slip mat is made of an elastic material.

[0010] Preferably, the upper surface of the support plate is flush with the upper surface of the heating pad.

[0011] Preferably, the four limiting grooves are symmetrical about each other with respect to the placement groove.

[0012] Preferably, the upper plate is provided with a pick-and-place flange, which is located at the end of the upper plate near the pick-and-place window.

[0013] Preferably, the heating pad is a silicone heating plate.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model sets a limiting groove on the support plate and installs an insert on the upper plate, which can not only limit the position but also make it easy to pick up and put down, thus realizing the quick assembly and disassembly of the upper plate.

[0015] 2. The present invention provides a horizontal groove on the insert so that it can be inserted into the upper plate, which is convenient to remove and reuse to reduce costs. An anti-slip pad is provided on the upper surface of the horizontal groove, which makes the connection between the insert and the upper plate more reliable, avoids relative displacement, and also avoids damage to the coating on the upper plate surface during the installation of the insert.

[0016] 3. This utility model improves the convenience of picking up and placing items by providing a pick-up and place flange on the upper plate. Attached Figure Description

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-4The 3D printed substrate shown includes a heated bed platform and an upper plate 1. The heated bed platform includes a support plate 3 and a heating pad. The upper surface of the support plate 3 has a placement groove 7, in which the heating pad is placed. The heating pad is a silicone heating plate. Since the heating pad is a flexible plate, the support plate 3 provides support, and the placement groove 7 on the upper surface assists in fixing and installing the heating pad.

[0021] The upper surface of the support plate 3 of this utility model is flush with the upper surface of the heating pad, so that the support plate 3 can not only support the upper plate 1, but also make the upper surface of the heating pad contact the heating pad, thereby improving the heat transfer efficiency.

[0022] Specifically, the support plate 3 has two limiting grooves 6 on each side. The four limiting grooves 6 are symmetrical about the placement groove 7 in pairs, so they will not interfere with the installation and placement of the heating pad. The upper plate 1 has two inserts 5 on each side, which correspond one-to-one with the limiting grooves 6. One end of the insert 5 can abut against the end of the limiting groove 6 away from the side of the support plate 3. The two abut against each other, which can restrict the movement of the upper plate 1 in the horizontal direction, thereby limiting the upper plate 1. Due to its own weight and the friction generated by the insert 5 abutting against the closed end of the limiting groove 6, the upper plate 1 will not move up or down relative to the support plate 3 during printing.

[0023] Specifically, the limiting groove 6 is a V-shaped groove, and the lower end face of the insert 5 is a contoured surface 9 that matches the limiting groove 6. The two downward-sloping surfaces of the limiting groove 6 guide the insert 5 into the limiting groove 6 to engage with it, facilitating quick and easy positioning and installation.

[0024] The insert 5 of this utility model has a horizontal groove 4 at one end, through which the insert 5 is inserted into the upper plate 1. An anti-slip pad 8 is provided on the upper surface of the horizontal groove 4. The anti-slip pad 8 is made of elastic material. This ensures a more reliable connection between the insert 5 and the upper plate 1, preventing relative displacement and avoiding damage to the coating on the upper surface of the upper plate 1 during installation. The insert 5 is detachably installed on the upper plate 1, allowing it to be removed and reused when the upper plate 1 is replaced, thus reducing costs.

[0025] The end of the limiting groove 6 near the side of the support plate 3 is not closed, so as to avoid the limiting groove 6 interfering with the placement of the insert 5.

[0026] Specifically, the upper plate 1 is provided with a pick-and-place flange 2, which is located at the end of the upper plate 1 near the pick-and-place window. This facilitates the operator's picking up or placing of items.

[0027] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
