Description

Technical Field

[0001] This utility model relates to the field of 3D printing auxiliary structure technology, specifically to an auxiliary structure that facilitates platform cleaning. Background Technology

[0002] With the rapid development of additive manufacturing technology, 3D printing processes such as fused deposition modeling (FDM) and sintering laser (SLS) have been widely applied in aerospace, medical, mold making, and education fields. During the printing process, support debris, escaping powder, molten stringing, or coating peeling inevitably remain in the platform's working area. If not cleaned in time, this will directly lead to a decrease in the bonding strength between subsequent printing layers, warping of the first layer, nozzle clogging, or even scratching of the printhead, significantly reducing equipment uptime and finished product yield.

[0003] However, existing cleaning methods generally rely on manual labor, requiring operators to periodically enter the forming chamber with hand scrapers, brushes, or vacuum cleaners. This method is not only inefficient and labor-intensive, but human factors can also lead to inconsistent cleaning efforts, overlooking corner areas. Furthermore, frequent opening and closing of the chamber doors can disrupt the temperature field and atmosphere balance, reducing processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary structure that facilitates platform cleaning, thereby solving the problems of low efficiency, inconsistent cleaning, and impact on equipment temperature field caused by existing manual cleaning methods.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An auxiliary structure for facilitating platform cleaning includes an auxiliary cleaning mechanism disposed on a 3D printing platform. The 3D printing platform has a working area. The auxiliary cleaning mechanism includes a scraping component for cleaning the working area. A negative pressure collection component is connected to the scraping component. The scraping component is also provided with a driving component, which is disposed at the lower end of the 3D printing platform.

[0007] Furthermore, two symmetrical grooves for installing scraping components are provided on both sides of the above-mentioned work area, and guide grooves are provided in the grooves. Two mounting seats for installing drive components are symmetrically provided at the lower end of the 3D printing platform.

[0008] Furthermore, the aforementioned scraping assembly includes a sliding seat slidably installed in a slide groove, guide blocks on both sides of the sliding seat, the guide blocks slidably installed in a guide groove, a mounting cover at the upper end of the sliding seat, a movable seat connected to the drive assembly at the lower end of the sliding seat, and a scraper rotatably installed inside the mounting cover.

[0009] Furthermore, an angle adjustment component is provided on one side of the aforementioned scraper. The angle adjustment component uses a stepper motor, and the output end of the stepper motor is connected to the scraper.

[0010] Furthermore, eight telescopic protective covers are symmetrically arranged on both sides of the aforementioned sliding seat. The eight telescopic protective covers are respectively installed at the upper and lower openings of the slide groove. One end of the telescopic protective cover is fixedly connected to the sliding seat, and the other end is fixedly connected to the side wall of the slide groove.

[0011] Furthermore, the aforementioned negative pressure collection assembly includes several connecting pipes that communicate with the mounting cover, and the other end of the connecting pipes is connected to the negative pressure collection box.

[0012] Furthermore, the aforementioned connecting pipe includes a first bent pipe fixedly connected to the mounting cover and a second bent pipe fixedly connected to the negative pressure collection box, with the first bent pipe and the second bent pipe connected by a telescopic corrugated pipe.

[0013] Furthermore, the aforementioned drive assembly includes a screw rotatably mounted on a mounting base, two guide rods symmetrically arranged on both sides of the screw, the screw being threadedly connected to the movable base, the guide rods being slidably connected to the movable base, and the screw being driven by a motor.

[0014] This utility model has the following beneficial effects:

[0015] This invention integrates the three major functions of "scraping, negative pressure collection, and driving" into a single auxiliary cleaning mechanism, which is arranged around the perimeter and bottom of the 3D printing platform. This achieves an independent cleaning route that is completely decoupled from the printing motion axis, enabling the platform to be cleaned online without stopping the machine or opening the door, thus significantly improving the equipment's working efficiency.

[0022] like Figures 1-3 As shown, this embodiment provides an auxiliary structure for easy platform cleaning, including an auxiliary cleaning mechanism 200 disposed on a 3D printing platform 100. The 3D printing platform 100 has a working area 101. The auxiliary cleaning mechanism 200 includes a scraping component 300 for cleaning the working area 101. A negative pressure collection component 400 is connected to the scraping component 300. The scraping component 300 is also provided with a driving component 500. The driving component 500 is disposed at the lower end of the 3D printing platform 100. In use, the driving component 500 drives the scraping component 300 to move along the working area 101 to scrape off the adhering material on the surface of the working area 101. At the same time, the negative pressure collection component 400 collects the scraped adhering material.

[0023] like Figure 3 As shown, two symmetrical grooves 102 for mounting the scraping component 300 are provided on both sides of the working area 101. The grooves 102 are provided with guide grooves 103. Two mounting seats 104 for mounting the drive component 500 are symmetrically provided at the lower end of the 3D printing platform 100. In use, the scraping component 300 is driven to move along the grooves 102 by the drive component 500.

[0024] like Figure 4As shown, the scraping assembly 300 includes a sliding seat 301 slidably mounted in a slide groove 102. Guide blocks 302 are provided on both sides of the sliding seat 301, and the guide blocks 302 are slidably mounted in a guide groove 103. A mounting cover 303 is provided at the upper end of the sliding seat 301, and a movable seat 304 connected to the drive assembly 500 is provided at the lower end of the sliding seat 301. A scraper 305 is rotatably mounted inside the mounting cover 303. An angle adjustment component is provided on one side of the scraper 305, and the angle adjustment component uses a stepper motor 306. The output end of the machine 306 is connected to the scraper 305. Eight telescopic protective covers 307 are symmetrically arranged on both sides of the sliding seat 301. These eight telescopic protective covers 307 are respectively located at the upper and lower openings of the slide groove 102. One end of each telescopic protective cover 307 is fixedly connected to the sliding seat 301, and the other end is fixedly connected to the side wall of the slide groove 102. The negative pressure collection assembly 400 includes several connecting pipes 401 that communicate with the mounting cover 303. The other end of each connecting pipe 401 is connected to the negative pressure collection box 405. 01 includes a first bent pipe 402 fixedly connected to the mounting cover 303 and a second bent pipe 404 fixedly connected to the negative pressure collection box 405.

Two guide rods 502 are symmetrically arranged on both sides of the screw 501. The screw 501 is threadedly connected to the movable base 304, and the guide rods 502 are slidably connected to the movable base 304. Driven by motor 503, the angle of scraper 305 is adjusted by stepper motor 306 to make scraper 305 closely adhere to the surface of working area 101. Then, motor 503 drives screw 501 to rotate, causing moving seat 304 to slide along guide rod 502, which in turn drives scraper 305 to move.

Then, the screw 501 is driven to rotate by the motor 503, so that the moving seat 304 slides along the guide rod 502, thereby moving the scraper 305. The scraper 305 scrapes off the adhering substances on the surface of the working area 101. At the same time, the scraped adhering substances are sucked into the negative pressure collection box 405 through the negative pressure collection box 405 and the connecting pipe 401, thereby completing the cleaning of the working area 101.
