Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to an integrated device for secondary curing and drying of 3D printed products. Background Technology

[0002] 3D printing is a rapid prototyping technology that uses digital model files as a basis and employs powdered metal or plastic and other bondable materials to construct objects layer by layer. During the 3D printing process, the internal resin may not be fully polymerized after printing, so secondary curing and drying operations are required. Secondary curing can promote the resin to fully undergo photocuring reaction, enhancing the mechanical properties and stability of the product. At the same time, the product may absorb or retain a certain amount of moisture during the printing process. Drying can remove this moisture, preventing problems such as deformation and mold growth due to moisture residue, thus improving product quality and service life.

[0003] Existing 3D printed products have the following defects during secondary curing and drying:

[0004] 1. Curing and drying need to be carried out at two different workstations, which not only increases equipment costs and space usage, but also makes the operation process cumbersome. It requires frequent manual transfer of products, which can easily lead to damage to the products during the transfer process and affect product quality.

[0005] 2. The curing lamps are used in fixed positions and there are usually multiple lamps, making it impossible to adjust the distance between the product and each lamp. The distance between the curing lamp and the object has a significant impact on the curing effect and efficiency. If the distance is too close, the local surface temperature may become too high, resulting in over-curing problems such as scorching and deformation. It may also cause the curing reaction to be too fast, generating internal stress and affecting product quality. If the distance is too far, there will be more light loss during transmission, reducing the energy density reaching the object surface, decreasing curing efficiency, and making the curing depth shallower. This may result in insufficient curing and poor flexibility. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please refer to Figures 1 to 6 Example 1:

[0032] This utility model proposes an integrated device for secondary curing and drying of 3D printed products, including: a mounting component 1 and a curing component. The mounting component 1 includes a mounting base 101, a drying column 102, a rotating table 103, a rotary motor 104, and a protective cover 4. The drying column 102 is fixedly mounted on the top of the mounting base 101, and the rotating table 103 is rotatably connected to the top of the mounting base 101. The rotary motor 104 is fixedly mounted on the bottom of the mounting base 101, and the rotary motor 104 and the rotating table 103 are connected by a gear set. The protective cover 4 is inserted into the top of the mounting base 101. The curing component includes a light source mechanism 2, which includes a positioning plate 201 and four curing lamp rods 202. The positioning plate 201 is rotatably connected inside the mounting base 101, and the curing lamp rods 202 are inserted into the top of the mounting base 101. The included angle between adjacent curing lamp rods 202 is 90 degrees, and curing lamps are installed on the side of the curing lamp rods 202.

[0033] The curing assembly also includes an adjustment mechanism 3, which includes an adjustment motor 301 and a positioning rod 302. The adjustment motor 301 is fixedly installed on the side of the mounting base 101, and the positioning rod 302 is rotatably connected inside the mounting base 101. One end of the positioning rod 302 is connected to the rotating shaft of the adjustment motor 301.

[0034] The rotary motor 104, the regulating motor 301, and the hot air blower are electrically connected to an external power supply and control device. Their specific structure and working principle are existing mature technologies and will not be described in detail here.

[0035] The positioning plate 201 and the rotating table 103 are on the same axis of rotation, and there are four drying columns 102. The included angle between adjacent drying columns 102 is 90 degrees, and the included angle between adjacent drying columns 102 and curing lamp poles 202 is 45 degrees. In use, by setting up the rotating table 103 and multiple sets of curing lamp poles 202, the product can be irradiated from all directions during rotation, achieving a more uniform secondary curing effect. The rotating motor 104 can drive the rotating table 103 to rotate through the gear set, thereby realizing the product's rotation on the top of the mounting base 101. This allows the product to be dried and cured from all directions during rotation, and the drying and curing are uniform and stable. The protective cover 4 can effectively reduce heat loss. By making the protective cover 4 transparent, it is also convenient for operators to observe the processing status of the product inside the equipment.

[0036] The mounting base 101 has a hot air channel 1011 inside, and the drying column 102 has a connecting channel 1021 inside. One end of the hot air channel 1011 is connected to the hot air blower through a pipe, and the other end of the hot air channel 1011 is connected to the connecting channel 1021. The connecting channel 1021 has a drying channel 1022 on the side facing the rotating table 103. In use, the mounting assembly 1 can realize the secondary drying operation of the product. The hot air blower supplies hot air into the interior of the hot air channel 1011 through the pipe. The hot air can then enter the interior of the connecting channel 1021 through the hot air channel 1011 and finally be sprayed out from the drying channel 1022. The hot air finally blows onto the surface of the product to perform a secondary drying operation, remove the moisture inside the product, and prevent the product from deforming, moldy, or other phenomena due to moisture residue. The product is stable in use.

[0037] The positioning disk 201 has an arc-shaped synchronous positioning groove 2011 inside, and the bottom of the curing lamp post 202 has a synchronous positioning post 2021. The synchronous positioning post 2021 is inserted into the synchronous positioning groove 2011. The curing lamp post 202 can only move radially along the mounting base 101 inside the mounting base 101. The positioning rod 302 has threads on the outside of its body and is screwed into the inside of one of the curing lamp posts 202 through the thread. In use, the curing assembly can realize the secondary curing operation of the product by irradiating the product surface with the curing lamp on the curing lamp post 202. The product is cured evenly and stably during rotation. The distance between the curing lamp post 202 and the product can be adjusted by the adjustment mechanism 3 so that the curing lamp and the product are aligned. The secondary curing operation is always performed at a suitable distance. When the adjusting motor 301 rotates, it drives the positioning rod 302 to rotate. When the positioning rod 302 rotates, it drives the curing lamp rod 202, which is threaded to it, to move, changing the distance between it and the product. At the same time, the curing lamp rod 202 can drive the positioning disk 201 to rotate through the cooperation of its bottom synchronous positioning column 2021 and synchronous positioning groove 2011. Thus, when the positioning disk 201 rotates, the cooperation of the other synchronous positioning columns 2021 and synchronous positioning groove 2011 can drive the other curing lamp rods 202 to move synchronously, thereby changing the distance between each curing lamp rod 202 and the product. It is quick to adjust, easy to use, and adaptable to the rapid secondary curing operation of products of different volumes, with extremely strong adaptability.

[0038] The working principle of this embodiment is as follows: Placing the product on the rotating table 103 enables secondary curing and drying. The rotating motor 104 drives the rotating table 103 to rotate via a gear set, thus enabling the product to rotate on top of the mounting base 101. This allows for omnidirectional drying and curing during rotation. The mounting component 1 enables secondary drying. A hot air blower supplies hot air through a pipe into the hot air channel 1011. The hot air then enters the connecting channel 1021 and finally exits from the drying channel 1022. The hot air ultimately blows onto the surface of the product, performing secondary drying to remove internal moisture and prevent deformation or mold growth due to residual moisture. The curing component enables secondary curing by illuminating the product surface with the curing lamp on the curing lamp post 202. Yes, the product cures evenly and stably during rotation. The distance between the curing lamp pole 202 and the product can be adjusted by the adjustment mechanism 3, so that the curing lamp and the product are always kept at a suitable distance for secondary curing. When the adjustment motor 301 rotates, it can drive the positioning rod 302 to rotate. When the positioning rod 302 rotates, it can drive the curing lamp pole 202 with its threaded engagement to move, changing the distance between it and the product. At the same time, the curing lamp pole 202 can drive the positioning disk 201 to rotate through the cooperation of its bottom synchronous positioning column 2021 and synchronous positioning groove 2011. Thus, when the positioning disk 201 rotates, the cooperation of the other synchronous positioning columns 2021 and synchronous positioning groove 2011 can drive the other curing lamp poles 202 to move synchronously, thereby changing the distance between each curing lamp pole 202 and the product, adapting to the rapid secondary curing operation of products of different volumes.

[0039] In another embodiment, a temperature sensor is installed inside the protective cover 4. The temperature sensor can monitor the internal temperature and shut off the power to the hot air blower when the temperature is too high, so as to prevent the product from being damaged due to overheating and further improve the stability of the device.
