Description

Technical Field

[0001] The present application relates to the field of 3D printing technology, and in particular to a quick-release molding platform and a light-curing printer. Background Art

[0002] At present, 3D printing molding technology has been widely used. Among them, light-curing printers generally use a common molding platform with a molding surface, a molding table and a connecting seat as an integrated manufacturing unit. After each printing is completed, this integrated molding platform needs to be disassembled, the model removed, the residue removed and cleaned before it can be used again. If only one molding platform is used, the above-mentioned disassembly and cleaning steps need to be completed before it can be used again, which is not conducive to quickly carrying out the next printing task. If a machine is equipped with multiple molding platforms for replacement, the cost of use is relatively high.

[0003] In addition, there is currently a magnetic plate-type forming platform, which can also achieve rapid printing and replacement at low cost; however, this magnetic plate-type forming platform is more suitable for small-area printing machines. When used in large-area printing machines, when printing large models and the model demolding force is large, the magnetic plate is prone to displacement or falling off. Therefore, its use structure is not stable and is rarely used on large-area printers; and when a strong magnetic adsorption magnetic plate is used on the forming platform, the strong magnetism will also have a certain negative impact on the circuit of the lower light-transmitting screen.

[0004] Therefore, in order to solve and avoid the above problems, it is necessary to provide a forming platform that has a stable structure and can meet the needs of rapid switching printing. Utility Model Content

[0005] The purpose of the embodiments of the present application is to propose a quick-detachable forming platform and a light-curing printer using the quick-detachable forming platform. The forming platform of the present application has a stable structure and can enable a light-curing printer to continuously and quickly switch and perform multiple printing tasks at a relatively low cost by only replacing the forming surface and the forming table.

[0006] The embodiment of the present application provides a quick-release forming platform, comprising a forming table, a connecting seat, and a connecting unit; wherein the forming table comprises a forming surface and a wedge buckle;

[0007] A wedge hole is provided on the connecting base; the connecting unit is connected to the connecting base; the connecting unit is used to connect to the lifting mechanism of the light-curing printer; the forming surface is the bottom plane of the forming table, and the wedge buckle is provided on the upper part of the forming table; the forming surface is used for model attachment forming during light-curing printing; the wedge buckle is detachably wedged and fastened with the wedge hole, so that the forming table and the connecting base are detachably fixed.

[0008] Furthermore, the wedge hole includes a button hole and a wedging groove; the button hole and the wedging groove are connected to form an integral hole; the button hole is a long and wide-sided hole; the wedging groove is a short and narrow-sided hole; when the wedge buckle and the wedge hole are wedged and fastened, the wedge buckle passes upward through the button hole and then moves toward the side of the wedging groove, and then the wedge buckle is wedged and fastened.

[0009] Furthermore, the wedge buckle includes a wedge, a wedge stop, a buckle top, and a raised portion; the wedge is vertically connected to the wedge stop; the buckle top is vertically connected to the wedge and the wedge stop at the same time; and a raised portion is also provided on the buckle top.

[0010] Furthermore, when the wedge buckle is wedged and tightened with the wedge hole, the wedge, wedge stop, buckle top and raised portion pass upward through the buckle hole and then move toward one side of the wedging groove, so that the wedge enters the wedging groove and is wedged; the wedge stop clamps the inner groove edge of the buckle hole for stopping; the lower part of the buckle top is buckled with the upper surface of the connecting seat to prevent the forming table and the connecting seat from loosening and detaching up and down; the raised portion uses the lower inclined surface as a guide surface to enable the buckle top to be quickly buckled with the connecting seat.

[0011] Furthermore, the forming table further includes a handle; the handle is arranged on one side of the forming table; the handle is used to push the forming table for disassembly or fixation.

[0012] Furthermore, an inner shrinkage edge is provided on one side of the connecting seat; the inner shrinkage edge is an inner groove formed by inward contraction of one side of the connecting seat; the inner shrinkage edge is used to accommodate the buckle part, thereby making the overall shape of the forming table and the connecting seat neater.

[0013] Furthermore, structural ribs are provided on the upper portion of the forming table, and the structural ribs are used to enhance the overall structural strength of the forming table.

[0014] Furthermore, a friction enhancement layer is provided on the surface of the molding surface, and the friction enhancement layer is used to enhance the adhesion of the model during photocuring printing.

[0015] Preferably, the connecting unit adopts a ball head structure or a frame structure.

[0016] Preferably, there are multiple wedge buckles and multiple wedge holes.

[0017] Preferably, the forming table is made of plastic, and the micro-deformation property of the plastic can facilitate the removal of the model.

[0018] Furthermore, the quick-release molding platform further includes a fixed column and a fastening handle; the connecting unit is detachably fixed to the fixed column; the fixed column is used to dock with the lifting mechanism of the light-curing printer, and the fastening handle is used to lock the fixed column and the lifting mechanism.

[0019] The present application also aims to provide a light-curing printer, specifically the light-curing printer includes the above-mentioned quick-release molding platform.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The quick-release build platform proposed in the embodiments of the present application enables removable wedging and fastening of the wedge buckle and wedge hole, enabling the build platform and the connecting base to be removably fixed. Therefore, by simply replacing the build surface and the build table, a single stereolithography printer can rapidly switch between multiple print jobs at a relatively low cost compared to an integrated build platform.

[0022] 2. The quick-release molding platform proposed in the embodiments of the present application can be quickly disassembled by simply pushing the molding table horizontally and then lowering it for placement. This is simpler than rotating the fastening handle on conventional machines, making it more convenient to use.

[0023] 3. The quick-release build platform proposed in this embodiment can be quickly disassembled by simply pushing the build platform horizontally and then lowering it for removal. Compared to magnetic plate-type build platforms, which require forceful removal of the magnetic plate, this is more labor-saving and convenient to use.

[0024] 4. The quick-release build platform proposed in this application embodiment can be quickly disassembled by simply pushing the build platform horizontally and then lowering it for placement. Compared to magnetic plate-type build platforms, it is more suitable for larger print areas and eliminates the problem of strong magnets affecting the light-transmitting screen circuit.

[0025] 5.

Compared with the magnetic plate-type forming platform, the structure is more stable in use.

[0026] 6. In an embodiment of the present application, a quick-release molding platform is proposed. When the molding platform is made of plastic, the micro-deformation properties of the plastic can be utilized to facilitate removal of the attached model.

[0027] 7. A quick-release forming platform proposed in an embodiment of the present application can also adopt a fixed column and a fastening handle, thereby having two quick-release structures at the same time, namely a first quick-release structure where the forming surface and the forming table are located, and a second quick-release structure where the fixed column is connected to the printer lifting mechanism.
