Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a quick-disassembly device for a light-curing 3D printing resin tank. Background Art

[0002] The resin tank is a device for holding photosensitive resin on a light-curing 3D printer. It has a transparent film at the bottom and is installed on a base plate of the 3D printer. The base plate is provided with an ultraviolet light source system. During printing, the ultraviolet light source irradiates ultraviolet light, which passes through the transparent film to cure the photosensitive resin in the resin tank. Furthermore, the photosensitive resin is cured on the building platform, which is pulled up to take away the cured photosensitive resin and then descends to continue the next curing work. This cycle is repeated layer by layer to complete the light-curing 3D printing process.

[0003] The resin tanks of existing light-curing 3D printers on the market are usually fixed with bolts. Hand-tightened knurled bolts are provided on the left and right sides of the resin tank. The resin tank is locked and fixed to the base plate of the printer by manually rotating the bolts. This method requires the knurled bolts to be aligned with the fixed holes on the base plate of the printer before the locking operation can be performed. It is difficult for beginners to align them without a certain concept of the positions of the fixed holes on the base plate. Furthermore, the knurled bolts need to be rotated several times during the locking process to complete the locking. The loading and unloading process is cumbersome and complicated. In addition, if the manufacturer does not use an anti-slip knurled bolt design, there is a risk that the knurled bolts will slip out of the resin tank, increasing the risk of losing the knurled bolts. When installing the resin tank, an action of reinstalling the knurled bolts is also added, thereby reducing the user experience, the production efficiency of the equipment and the competitiveness of the product.

[0028] See attached Figure 1-3 The utility model provides a quick-release device for a light-curing 3D printing resin tank, comprising a fixing frame 300, a resin frame 100 and a clamping plate assembly 200; one side of the clamping plate assembly 200 is fixed to one side of the resin frame 100, and the clamping plate assembly 200 and the resin frame 100 enclose a space for accommodating resin;

[0029] The clamping plate assembly 200 has a fixing ear 210 extending from the outside of the resin frame 100, and the fixing frame 300 is provided with a positioning groove 310 corresponding to the position of the fixing ear 210, and the positioning groove 310 can be interference fit with the fixing ear 210;

[0030] When the side of the resin frame 100 fixing the clamping plate assembly 200 moves closer to or farther from the fixing frame 300 , the fixing ear 210 can be engaged with or separated from the positioning groove 310 .

[0031] Based on the above technical features, by fixing the splint assembly 200 to the resin frame 100, the user places the resin frame 100 in the fixed frame 300. Further, the user pushes the resin frame 100 downward so that the fixing ear 210 is engaged and fixed in the positioning groove 310 from the bottom, thereby completing the locking installation of the resin frame 100. On the contrary, the user pulls the resin frame 100 upward to unlock it. The entire process only requires "one push and one pull" to complete the loading and unloading of the resin frame 100 and the splint assembly 200, which is convenient and quick, and eliminates the tedious and complicated steps of aligning the positioning holes and then tightening the knurled bolts in the traditional resin tank.

[0032] A first guiding slope is provided on one side of the positioning groove 310 close to the clamping plate assembly 200 , and the first guiding slope is inclined from top to bottom to guide the fixing ear 210 .

[0033] Among them, the splint assembly 200 includes an upper splint 220, a release film 230 and a lower splint 240 arranged in sequence from top to bottom; the splint assembly 200 is fastened to the resin frame 100 through fasteners; the photosensitive resin is received by the release film 230, and the photosensitive resin is enclosed by the resin frame 100.

[0034] In this embodiment, the inner side of the fixed frame 300 includes a plurality of spaced-apart boss units, which form a positioning groove 310. The boss unit includes a fixed boss 320 and a guide boss 330. The guide boss 330 is disposed above the fixed boss 320. One end of the guide boss 330 protrudes outward from the fixed boss 320, and a first guide slope is disposed on the protruding end of the guide boss 330. The positioning groove 310 is formed by adjacent boss units to achieve the interlocking fixation of the fixed ear 210. Specifically, the guide boss 330 achieves the guided sliding of the fixed ear 210, thereby achieving the interlocking fixation between the fixed ear 210 and the fixed boss 320. The upper limit is achieved by the guide boss 330 protruding outward. When installing the resin frame 100 , the resin frame 100 is pushed downward, and the fixing ears 210 will be interference-fitted with the boss units under the action of the thrust, and the force generated by the interference fit will fix the clamping plate assembly 200 and the resin frame 100 .

[0035] Furthermore, a chamfer is provided between the guide boss 330 and the fixed boss 320 , and the chamfer is provided to facilitate the installation and separation of the clamping plate assembly 200 from the guide boss 330 to the fixed boss 320 .

[0037] Specifically, handles 130 are provided on both sides of the resin frame 100 to facilitate the user to install and remove the resin frame 100 .

[0038] Furthermore, the resin frame 100 and the fixing frame 300 are both provided with guiding slopes on their upward sides. The fixing frame 300 guides the installation of the resin frame 100 and the clamping plate assembly 200 through the guiding slopes, and the resin frame 100 guides the injection of the photosensitive resin through the guiding slopes.

[0039] Among them, the resin frame 100 has a side wall extending from the bottom, and an anti-fool column 120 is set on the inner side of the side wall. The side of the splint assembly 200 corresponding to the anti-fool column 120 is provided with an anti-fool notch 250 to avoid the error in the installation direction of the splint assembly 200 and the resin frame 100.

[0040] In this embodiment, the splint assembly 200 also includes a silicone plate 260, which is respectively located between the upper splint 220 and the release film 230 and between the resin frame 100 and the upper splint 220. By setting the elastic deformation of the silicone plate 260, the gap between the release film 230 and the splint module during installation can be filled to avoid leakage of photosensitive resin.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
