Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and more specifically, to a thermosetting apparatus for a 3D printer. Background Technology

[0002] Workpieces printed by photopolymerization usually require further curing to stabilize them. Common post-photopolymerization treatments include UV curing and thermal curing.

[0003] In existing technologies, thermosetting requires heating the air inside the heating chamber to a certain temperature and then holding the workpiece in the chamber for a specific time to achieve the thermosetting effect. Conventional thermosetting devices control the start and stop of individual PTC heating blocks to maintain the temperature within a certain range in the heating chamber. However, PTC heating blocks have a characteristic where their starting power is often much greater than their actual operating power. For example, a PTC heating block with an operating power of 205W can reach a peak power of 310W during startup and maintain that peak power for about 3 seconds. Therefore, the power supply matched to this heating block must have sufficient power reserve for buffering, necessitating the use of a larger power supply, increasing cost and installation space. Furthermore, thermosetting devices with a single PTC heating block typically have the heating block installed at the bottom of the heating chamber, which can easily lead to a significant temperature difference between the bottom and top of the workpiece during thermosetting, negatively impacting the uniformity of the workpiece's thermosetting process.

[0004] Therefore, it is necessary for the inventors to design a new thermosetting device for 3D printers to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a 3D printer thermosetting device to solve the problems of high power requirements and uneven workpiece heating in related technologies.

[0006] To achieve the above objectives, this application provides a 3D printer thermosetting device, including a housing and a power supply assembly. A placement stage is rotatably mounted on the bottom of the housing. A plurality of heating blocks are fixedly mounted on the lower part of the housing. The heating blocks are arranged in a circumferential array on the outside of the placement stage. A power monitoring component is fixedly connected to each heating block. The heating blocks are electrically connected to the power monitoring component and the power supply assembly.

[0007] It also includes an operation panel, which is electrically connected to the power supply component, the heating block, and the power monitoring component.

[0008] Preferably, a motor is fixedly installed at the bottom of the outer casing, and the output shaft of the motor passes through the outer casing and is fixedly connected to the placement platform.

[0013] Preferably, the operation panel is fixedly mounted on the outer wall of the housing.

[0014] Preferably, a sealing cover is rotatably provided on the top of the outer casing.

[0029] like Figures 1 to 4 As shown, a 3D printer thermosetting device includes a housing 1 and a power supply assembly 2. A placement platform 3 is rotatably mounted on the bottom of the housing 1. Several heating blocks 4 are fixedly mounted inside the lower end of the housing 1. The heating blocks 4 are arranged in a circumferential array on the outside of the placement platform 3. A power monitoring component 5 is fixedly connected to each heating block 4. The heating blocks 4 are electrically connected to the power monitoring component 5 and the power supply assembly 2. The device also includes an operation panel 6, which is electrically connected to the power supply assembly 2, the heating blocks 4, and the power monitoring component 5.

[0030] Specifically, the single high-power PTC heating block 4 in conventional technology is decomposed into multiple low-power heating blocks 4 in this embodiment. The real-time power of each heating block 4 is monitored in real time by the power monitoring component 5. When the heating block 4 is started for heating, the start and stop of each heating block 4 is controlled in stages by the operation panel 6. For example, one heating block 4 is started first. At the start, the peak power of the heating block 4 is relatively high. After the peak power drops to the working power, the next heating block 4 is started. At this time, the instantaneous power of the power supply is the working power of one heating block 4 plus the peak power of one heating block 4. Taking the decomposition of a large heating block 4 into two small heating blocks 4 as an example: a PTC heating block 4 with a working power of 205W is set as two small PTC heating blocks 4 with a working power of 105W. The peak power of the small heating block 4 when it is started is 155W. In this way, the maximum instantaneous power of the power supply is only 105W plus 155W, which equals 260W, which is much lower than the heating power of a single heating block 4 of 310W. Therefore, a relatively small power supply can be selected, saving costs and installation space. At the same time, multiple low-power heating blocks 4 are evenly arranged around the placement platform 3, and the placement platform 3 is set to rotate. When the heating blocks 4 are not turned on at the same time, the placement platform 3 is driven to rotate, which can make the workpiece heat more evenly and improve the performance of the workpiece.

[0031] In this embodiment, by setting multiple heating blocks 4 and controlling the start and stop of each heating block 4 individually, and by monitoring the real-time power of the heating block 4 in real time through the power monitoring component 5, the peak power times of each heating block 4 can be staggered, thereby reducing the size of the power supply model, reducing costs and installation space, and by rotating the placement platform 3, the workpiece can be heated more evenly.

[0032] A motor 7 is fixedly installed at the bottom of the outer casing 1, and the output shaft of the motor 7 passes through the outer casing 1 and is fixedly connected to the placement platform 3. Specifically, the placement platform 3 is driven by the motor 7. Depending on actual needs, other drive structures can also be used to drive the rotation of the placement platform 3.

[0033] The housing 1 has several snap-fit ​​slots 8 fixedly installed inside, and the heating block 4 is fixedly snapped into the snap-fit ​​slots 8. The bottom of the snap-fit ​​slot 8 has a through-hole 9 for wiring. Specifically, the PTC heating block 4 is installed in the snap-fit ​​slot 8. Since the heating block 4 needs to be electrically connected to the power supply and the power monitoring component 5, a through-hole 9 for cable wiring also needs to be reserved.

[0034] The number of heating blocks 4 is even. Specifically, setting it to an even number makes the positions of the heating points inside the outer shell 1 more symmetrical, thereby better ensuring the uniformity of workpiece heating.

[0035] The power monitoring component 5 includes a power meter, which is fixedly installed outside the housing 1. The power meter is electrically connected to the heating block 4 via a cable. Specifically, the instantaneous power of the heating block 4 can be monitored in real time by electrically connecting the power meter to the heating block 4. In addition, a voltmeter and an ammeter can also be electrically connected to it to indirectly obtain the power of the heating block 4.

[0036] A temperature sensor 10 is also fixedly installed inside the outer casing 1, and the temperature sensor 10 is electrically connected to the operation panel 6. Specifically, the real-time temperature inside the outer casing 1 is obtained through the temperature sensor 10, and then the working status of the heating block 4 is controlled through the operation panel 6.

[0037] The operation panel 6 is fixedly mounted on the outer wall of the housing 1. Specifically, the operation panel 6 is directly mounted on the housing 1, allowing workers to operate and react quickly. One worker can control one of these devices, resulting in higher efficiency.

[0038] A sealing cover 11 is rotatably mounted on the top of the outer casing 1. Specifically, the sealing cover 11 is tightened during heating to prevent heat loss.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
