Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a 3D printing layer curing box. Background Technology

[0002] With the popularization of photopolymer 3D printing technology in industrial, medical, and consumer model fields, the 3D printing layer curing box, as a core post-processing equipment, uses ultraviolet light of a specific wavelength to achieve layered directional curing of parts, which can increase the curing degree of parts from 60%-80% to more than 95%, effectively ensuring the mechanical properties and dimensional accuracy of parts.

[0003] When using existing 3D printing layer curing chambers to cure printed parts, the operating procedure is usually as follows: First, open the cover of the curing chamber and pull out the tray inside the chamber that holds the parts; then place the parts to be cured on the tray, and then push the tray back into the curing chamber. Start the equipment to perform the curing process on the parts.

[0004] After the curing process is complete, operators need to reach into the curing chamber to pull out the tray and remove the parts. During this process, the operator's hands or arms are very likely to come into contact with the inner wall of the curing chamber, posing a risk of burns. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a 3D printed layer curing box, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 3D printing layer curing box, comprising a curing box body for curing 3D printed parts, wherein the front side of the curing box body is open; A guide rail is installed on both the left and right sides of the curing chamber body along its depth direction. A vertical plate is slidably connected to the outside of both guide rails. A drive rod is hinged to the opposite side of each of the two vertical plates through a hinge shaft. The drive rods on both sides away from the vertical plate are hinged to the same frame via a hinge shaft, and a placement plate for placing parts is provided inside the frame. A connecting frame is installed between the two vertical plates on opposite sides. A cover plate is provided on the front side of the connecting frame, and the cover plate is used to control the opening and closing of the curing chamber body. Guide plates are provided on both the left and right sides of the inner wall of the curing chamber. Corresponding to the guide plates, a roller that cooperates with the guide plate is rotatably connected to the uppermost drive rod.

[0007] Furthermore, the placement plate is a honeycomb plate.

[0008] Furthermore, the two drive rods on one side are arranged in parallel.

[0009] Furthermore, the guide plate has a guide groove, and the roller is slidably connected inside the guide groove.

[0010] Furthermore, the guide groove includes two horizontal grooves and one inclined groove; The two horizontal grooves are connected by an inclined groove.

[0011] Furthermore, the inclined groove is inclined toward the opening of the curing chamber body and is distributed at an acute angle with the inner bottom wall of the curing chamber body.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This 3D printing layer curing chamber uses rollers on the top drive rod that work with guide grooves to automatically lift the frame when it is pulled out. This allows operators to pick up and put down parts without having to reach into the chamber, completely avoiding burns caused by touching the high-temperature chamber walls. The linkage design between the cover and the frame reduces ultraviolet leakage, further protecting the health of operators and complying with industrial equipment safety regulations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5In this embodiment, a 3D printing layered curing box solves the problem of burns caused by operators' hands touching the box wall when picking up and putting down parts by a combination of linkage push-pull and guide limiting structure. Specifically, it includes the curing chamber body 1, guide rail 2, vertical plate 3, drive rod 4, frame 5, placement plate 6, connecting frame 7, cover plate 8, guide plate 9, and rollers 10. All components work together to open and close the curing chamber and safely pick up and put away parts.

[0017] In detail, the main body of the curing chamber 1 is a rectangular sealed chamber made of stainless steel. The inner wall is equipped with ultraviolet lamps to provide the light source required for layer curing. The front of the chamber is open to serve as a channel for taking parts in and out. The inner wall is treated with high temperature resistance to withstand the heat generated by the ultraviolet lamps during long-term operation and prevent the chamber from deforming or aging.

[0018] Furthermore, there are two guide rails 2, which are installed along the depth direction of the left and right sides of the curing box body 1 respectively. They adopt a linear guide rail structure and have guide grooves on the outside for sliding connection of the vertical plate 3. This ensures that the vertical plate 3 can only move along the depth direction of the curing box body 1, and avoids the vertical plate 3 from shifting, which would cause the subsequent parts to be picked up or placed in a different position.

[0019] There are two vertical plates 3, made of aluminum alloy, which are slidably connected to the outside of the two guide rails 2 and can slide back and forth with the guide rails 2. Each of the two vertical plates 3 has a drive rod 4 hinged to its opposite side through a hinge shaft, which provides support and transmission for the frame 5. At the same time, a connecting frame 7 is installed between the two vertical plates 3 to realize the synchronous movement of the two vertical plates 3 and avoid structural imbalance caused by unilateral movement. The frame 5 is a rectangular frame made of metal, with a placement plate 6 fixed inside to support the parts to be cured. The frame 5 is connected to the vertical plates 3 through the drive rod 4 and can slide back and forth with the vertical plates 3 to move in and out of the curing chamber body 1, providing a stable bearing base for the loading and unloading of parts.

[0020] Furthermore, the placement plate 6 is made of honeycomb material with uniform honeycomb-shaped through holes on its surface. This reduces the overall weight and the load on the drive rod 4 and the vertical plate 3. It also allows ultraviolet light to penetrate the through holes, achieving uniform curing of the bottom of the parts and avoiding the problem of insufficient curing of the bottom of parts caused by traditional solid trays. The placement plate 6 is fixed to the frame 5 by snaps, and different specifications of placement plates can be replaced according to the size of the parts, improving the adaptability of the device.

[0021] In addition, the connecting frame 7 is a metal rod that connects the two vertical plates 3 to opposite sides, ensuring that the two vertical plates 3 slide back and forth synchronously, and preventing the frame 5 from tilting due to the single vertical plate 3 moving too fast; a cover plate 8 is fixed to the front of the connecting frame 7 to realize the linkage between the cover plate 8 and the vertical plate 3. When the vertical plate 3 slides back and forth, the cover plate 8 opens and closes the opening of the curing box body 1 synchronously.

[0022] In actual setup, the cover plate 8 is a rectangular plate made of stainless steel, the size of which is adapted to the front opening of the curing chamber body 1. A high-temperature resistant sealing strip is pasted on the inside to seal the opening of the curing chamber body 1, reducing ultraviolet leakage and heat loss. The cover plate 8 is linked to the vertical plate 3 through the connecting bracket 7, which does not require separate operation and simplifies the usage process.

[0023] Furthermore, there are two guide plates 9, which are fixed on the left and right sides of the inner wall of the curing box body 1, respectively, corresponding to the rollers 10 on the drive rods 4; the guide plates 9 are provided with guide grooves 11, which include two horizontal grooves and one inclined groove. The two horizontal grooves are connected by the inclined groove, which is inclined towards the opening of the curing box body 1 and is distributed at an acute angle with the bottom wall of the box body. It is used to guide the movement of the rollers 10, thereby controlling the rotation direction of the drive rods 4. There are two rollers 10, which are respectively installed on the two uppermost drive rods 4 and are slidably connected in the guide grooves 11 of the two guide plates 9. When they roll along the grooves, they guide the rotation of the drive rods 4 and control the movement trajectory of the frame 5.

[0024] The working principle of the above embodiments is as follows: (1) The operator pulls the cover plate 8 forward, and the cover plate 8 drives the two vertical plates 3 to slide forward along the guide rail 2 through the connecting frame 7; the vertical plates 3 drive the four drive rods 4 to move simultaneously, and the rollers 10 on the two uppermost drive rods 4 roll along the guide groove 11 of the guide plate 9. At this time, the rollers 10 enter the inclined groove from the horizontal groove inside the box of the guide groove 11. The acute angle trajectory of the inclined groove forces the uppermost drive rod 4 to rotate upward around the hinge axis, thereby driving the entire frame 5 to lift upward and move forward; when the vertical plate 3 slides to the front end of the guide rail 2, the frame 5 is completely pulled out of the curing box body 1, and because of the lifting effect, it is higher than the box opening, so the operator does not need to reach into the box to place the parts to be cured on the placement plate 6.

[0025] (2) After the parts are placed, the operator pushes the cover plate 8 backward. The cover plate 8 drives the vertical plate 3 to slide backward along the guide rail 2 through the connecting frame 7. The roller 10 of the uppermost drive rod 4 rolls into the box along the inclined groove of the guide groove 11. The drive rod 4 rotates downward around the hinge axis, and the frame 5 descends and moves into the box. When the roller 10 enters the horizontal groove of the guide groove 11, the frame 5 remains horizontal and continues to move backward until it is completely inside the curing box body 1 and fits the bottom of the box. At this time, the cover plate 8 moves to the front of the box with the vertical plate 3, closes the opening, and the sealing strip ensures that the box is sealed. The ultraviolet lamp is turned on, and the light irradiates the parts to begin layer curing. After curing, the ultraviolet lamp is turned off, and the cover plate 8 is pulled forward again. The vertical plate 3 drives the drive rod 4 to move. The roller 10 of the uppermost drive rod 4 enters the inclined groove from the horizontal groove along the guide groove 11. The frame 5 is lifted and pulled out of the box with the vertical plate 3. The operator safely removes the cured parts.
