Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a device for secondary curing and molding of photopolymer 3D printing resin. Background Technology

[0002] Photopolymer 3D printing is a manufacturing technology that uses laser irradiation to solidify liquid resin, layering it to form a final product. Because the material inside the workpiece is not fully cured within a certain time after initial processing and requires cleaning, the workpiece remains relatively soft. Therefore, a secondary curing process is necessary, typically involving irradiation with ultraviolet light to harden the material to meet usage requirements.

[0003] The existing Chinese patent announcement number CN216068712U describes a secondary photocuring device for 3D printed workpieces. According to its description, this device does not have a structure for drying water stains on the cleaned product. Therefore, after cleaning the product, it needs to be transferred to an external drying device for drying before secondary curing can be performed. This method requires multiple transfers, increasing the number of operation steps. If secondary curing is performed directly without drying, water stains may easily remain on the product surface.

[0004] Therefore, it is necessary to provide a new photopolymer 3D printing resin secondary curing molding device to solve the above-mentioned technical problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 This utility model provides a photocurable 3D printing resin secondary curing molding device, which includes: a base plate 1, a processing box 2 fixedly connected to the base plate 1, a side wall curing lamp 21 and a bottom curing lamp 22 fixedly installed on the side wall and bottom of the processing box 2 respectively, and an auxiliary component 3 provided on the top of the processing box 2.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 The auxiliary component 3 includes a box cover 31 and a support ring 33. The bottom of the box cover 31 abuts against the top of the processing box 2. An air inlet pipe 32 is fixedly connected inside the box cover 31. Corrugated telescopic pipes 321 are fixedly installed at the ends of the air inlet pipe 32. A suspension cylinder 331 is fixedly installed between the top of the support ring 33 and the top cover. A guide pipe 34 is fixedly connected at the bottom of the support ring 33. The inside of the guide pipe 34 is connected to the bottom end of the corrugated telescopic pipe 321. Multiple evenly distributed and connected nozzles 341 are fixedly installed at the bottom of the inner side of the guide pipe 34.

[0026] It should be noted that with the auxiliary component 3, during use, the staff can place the cleaned product on the support plate 42, and then the air generated by the external air pump can be blown onto the product surface through the nozzle 341 through the air inlet pipe 32. During this process, the suspension cylinder 331 and the drive motor 43 can be controlled to work, so that the nozzle 341 can completely dry the water stains on the outer wall of the product. There is no need to transfer the cleaned product multiple times, and it can also reduce the phenomenon of water stains remaining on the product surface during the secondary curing process.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The processing box 2 is provided with a support assembly 4, which includes a support frame 41. The support frame 41 is rotatably installed on the inner bottom of the processing box 2. A fixedly connected support plate 42 is installed on the top of the support frame 41, and a fixedly connected transparent plate 421 is embedded inside the support plate 42.

[0028] It should be noted that: by setting the transparent plate 421 inside the support plate 42, when the product is cured, the bottom curing lamp 22 located in the support frame 41 can smoothly irradiate the bottom of the product through the transparent plate 421, thereby achieving more comprehensive irradiation and curing of the outer wall of the product.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4 The support assembly 4 also includes a drive motor 43, which is fixedly installed at the bottom of the processing box 2. The drive end of the drive motor 43 is equipped with a fixedly connected drive gear 431. The drive gear 431 is provided with a meshing gear ring 411 on the outside, and the gear ring 411 is fixedly sleeved on the support frame 41. A fixedly connected water guide frame 5 is installed on the inner wall of the processing box 2. A connected drain pipe 51 is fixedly installed inside the water guide frame 5, and the end of the drain pipe 51 away from the water guide frame 5 extends to the outside of the processing box 2. A fixedly connected water guide plate 422 is installed on the side wall of the support plate 42. The water guide plate 422 is inclined, and the side wall of the water guide plate 422 is located above the water guide frame 5.

[0030] It should be noted that: by setting the drive motor 43, when the product is air-dried and secondary cured, the working drive motor 43 can drive the support frame 41 and the product on top to rotate through the meshing of the end drive gear 431 and the gear ring 411. This makes the air-drying and secondary curing of the product surface more uniform. In addition, the rotation speed of the drive motor 43 is relatively slow, which can avoid the phenomenon that the product will fall off the support plate 42 due to centrifugal force during rotation.

[0031] In this embodiment, since the side wall of the water guide plate 422 is located above the water guide frame 5, the water droplets flowing during the drying of the product can smoothly fall along the side wall of the water guide pipe into the water guide frame 5, so that they can be smoothly discharged outward through the drain pipe 51 in the water guide frame 5 later.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 A lifting cylinder 311 is fixedly installed at the bottom of the cover 31. The bottom end of the lifting cylinder 311 is fixedly connected to the top of the base plate 1. An exhaust pipe 313 is fixedly installed inside the cover 31, and a top curing light 312 is fixedly installed at the center of the bottom of the cover 31.

[0033] It should be noted that: with the lifting cylinder 311 in use, the working lifting cylinder 311 can drive the box cover 31 to move vertically, thereby controlling the positional relationship between the box cover 31 and the processing box 2, so that the box cover 31 can be in a closed state when the device is in use, and can be moved up and opened after the device is finished, so that the staff can take out and place the products.

[0034] With the exhaust pipe 313 in place, excess gas entering the processing chamber 2 can be smoothly discharged outward through the exhaust pipe 313 when the product is being dried.

[0035] It should also be noted that the top curing lamp 312, side wall curing lamp 21 and bottom curing lamp 22 in the device are all UV LED lamps, which are the mainstream choice in the market.

[0036] The working principle of the photopolymer 3D printing resin secondary curing molding device provided by this utility model is as follows:

[0037] When using this device, the operator can first connect the air inlet pipe 32 in this device to an external air pump or fan (not shown in the figure). Then, the cleaned product can be placed on the support plate 42. Then, the lifting cylinder 311 can be retracted through the external terminal controller. The retracted lifting cylinder 311 can drive the box cover 31 to move downward until the bottom of the box cover 31 touches the top of the processing box 2. At this time, the external air pump can be controlled to work.

[0038] Gas can be output into the nozzle 341 through the air inlet pipe 32, the corrugated telescopic pipe 321, and the air guide pipe 34, and then the gas can be discharged from the nozzle 341 towards the product. During this process, the suspension cylinder 331 and the drive motor 43 can be controlled to work. The extended suspension cylinder 331 can drive the nozzle 341 to move downward through the support ring 33, while the working drive motor 43 will drive the drive gear 431 to rotate slowly. The rotating drive gear 431 can drive the support frame 41 and the product on top to rotate slowly and synchronously through meshing with the gear ring 411, so that the gas sprayed by the nozzle 341 can be evenly blown and dried along the outer wall of the product from top to bottom.

[0039] There is no need to place the cleaned product in a separate air-drying device or let it air dry for a while before transferring it, which improves the user experience of this device. After the product is dried, the operation of the external air pump can be stopped and the suspension cylinder 331 can be controlled to retract and reset. Then, the side wall curing lamp 21, bottom curing lamp 22 and top curing lamp 312 in the device can be controlled to work. During this process, through the setting of the transparent plate 421 inside the support plate 42, the bottom curing lamp 22 can also smoothly irradiate and cure the bottom of the product, thereby improving the uniformity of the secondary curing of the product by this device.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
