[0031] 1. This invention provides a resin tank loading and unloading structure, including a base frame, a resin tank loading chamber, a resin tank conveying device, and a pushing device. The base frame is equipped with a printing device. The resin tank loading chamber is connected to the base frame and is suitable for holding a plurality of resin tank components. The resin tank conveying device is located between the resin tank loading chamber and the printing device to convey the resin tank components between the printing device and the resin tank loading chamber.

In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Example

[0054] This embodiment provides a resin tank loading and unloading structure, such as... Figures 1 to 6 As shown, it includes a base frame 1, a printing device 2, a resin tank loading chamber 3, a resin tank conveying device 5, a pushing device 6, and a resin tank recovery chamber 7.

[0055] like Figure 1 and Figure 3As shown, a plurality of support columns 12 are provided inside the base frame 1. The printing device 2 is positioned above the base frame 1 for 3D printing. The resin tank loading chamber 3 and the resin tank recycling chamber 7 are positioned on the base frame 1 and are arranged side by side. The resin tank conveying device 5 is connected to the base frame 1 and is positioned between the resin tank loading chamber 3 and the resin tank recycling chamber 7 to deliver the resin tank parts 4 in the resin tank loading chamber 3 to the working area of ​​the printing device 2, and to deliver the resin tank parts 4 used by the printing device 2 to the resin tank recycling chamber 7. The pushing device 6 is positioned on the same side of the resin tank loading chamber 3 and the resin tank recycling chamber 7, and is used to deliver the resin tank parts 4 in the resin tank loading chamber 3 into the resin tank conveying device 5, and to deliver the resin tank parts 4 used by the printing device 2 in the resin tank conveying device 5 to the resin tank recycling chamber 7. The resin tank loading chamber 3 is open on the side closest to the resin tank conveying device 5.

[0056] This invention utilizes a resin tank loading chamber 3, a resin tank conveying device 5, a pushing device 6, and a resin tank recovery chamber 7 working together. The pushing device 6 delivers the resin tank components 4 from the resin tank loading chamber 3 into the resin tank conveying device 5. The resin tank conveying device 5 then delivers the resin tank components 4 to the working area of ​​the printing device 2 for printing. After printing, the resin tank conveying device 5 delivers the used resin tank components 4 back to the top of the resin tank loading chamber 3, i.e., below the resin tank recovery chamber 7. The pushing device 6 then pushes the unused resin tank components 4 from the resin tank loading chamber 3 upwards. During this upward push, the unused resin tank components 4 push the used resin tank components 4 above them to the resin tank recovery chamber 7. The resin tank conveying device 5 then delivers the unused resin tank components 4 back to the working area of ​​the printing device 2 for printing. This cycle completes the automatic replacement of the resin tank components 4. Compared to the manual replacement in the prior art, this invention can automatically replace the resin tank components 4, achieving continuous printing and improving printing efficiency.

[0057] Meanwhile, since the resin curing process will leave some residue, which can damage the bottom surface of the resin tank 4, timely replacement can reduce the probability of damage to the resin tank 4 and improve the printing success rate.

[0058] like Figure 2As shown, the pushing device 6 includes a pushing motor 61, a pushing plate 62, and a threaded rod 63. The pushing motor 61 is connected to the base frame 1, and the pushing plate 62 is slidably connected to the support column 12 on the base frame 1. The pushing end of the pushing plate 62 is located at the bottom of the resin tank loading chamber 3 and abuts against the resin tank component 4. One end of the threaded rod 63 is connected to the output end of the pushing motor 61, and the other end of the threaded rod 63 is connected to the threaded hole on the pushing plate 62. During operation, the pushing motor 61 drives the threaded rod 63 to rotate. The threaded hole on the pushing plate 62 and the external thread on the outside of the threaded rod 63 cooperate with each other, so that the pushing plate 62 can move relative to the axis of the threaded rod 63 to push the resin tank component 4 to move inside the resin tank loading chamber 3.

[0059] It is understood that in some other embodiments, the pushing device 6 may also be a driving component such as a cylinder, which can also achieve the pushing of the resin tank 4.

[0060] like Figure 3 and Figure 4 As shown, the resin tank conveying device 5 includes a conveying motor 51, a pulley, a transmission belt 52, a clamping frame 53, a first elastic element 54, and an abutment element 55. The conveying motor 51 is connected to the base frame 1, the pulley is rotatably connected to the base frame 1, and the pulley is located on one side of the resin tank loading chamber 3. The transmission belt 52 is connected between the pulley and the output end of the conveying motor 51. The base frame 1 is provided with a slide rail 11, the clamping frame 53 is slidably connected to the slide rail 11, and the clamping frame 53 is fixedly connected to the transmission belt 52 by a fixing element 56. The clamping frame 53 has a through groove inside, and the resin tank component 4 in the resin tank loading chamber 3 passes through the through groove to the upper side of the clamping frame 53. There are two first elastic elements 54. The first elastic element 54 is disposed opposite to the side wall of the through groove. When the resin tank part 4 passes through the through groove, the first elastic element 54 has a yielding state due to elastic deformation caused by the compression of the resin tank part 4. The elastic force of the first elastic element 54 clamps the resin tank part 4 until the resin tank part 4 completely passes through the through groove. After that, the first elastic element 54 returns to its deformation and supports the bottom of the resin tank part 4. There are four abutment elements 55, which are disposed on the through groove. The abutment elements 55 have a barbed limiting part to limit the top of the resin tank part 4. Thus, the abutment elements 55 and the first elastic element 54 cooperate to fix both ends of the resin tank part 4 to achieve the fixation of the resin tank part 4. It can be understood that the number of the first elastic element 54 and the abutment elements 55 can be determined according to production needs.

[0061] like Figure 5As shown, the resin tank recovery chamber 7 is provided with at least a pair of relief plates 71, which are arranged opposite to each other. The relief plates 71 are elastic elements. When the resin tank conveying device 5 delivers the resin tank part 4 used by the printing device 2 to the bottom of the resin tank recovery chamber 7, the pushing device 6 pushes the resin tank part 4 in the resin tank loading chamber 3 upward, thereby pushing the resin tank part 4 used by the printing device 2 on the resin tank conveying device 5 into the resin tank recovery chamber 7. The relief plates 71 are deformed by the pressure of the resin tank part 4 until the resin tank part 4 is completely inside the resin tank recovery chamber. At this time, the resin tank part 4 is no longer in contact with the relief plates 71, and the relief plates 71 return to their original shape and support the resin tank part 4, keeping it inside the resin tank recovery chamber 7. Figure 6 As shown, the resin tank 4 has grooves on both sides for matching the relief piece 71.

[0062] like Figure 1 As shown, the resin tank loading and unloading structure also includes a sensor 8, which is connected to the base frame 1. The sensor 8 is located on the open side of the resin tank loading chamber 3 and is electrically connected to the push motor 61. It is used to detect whether there is a resin tank component 4 above the open side of the resin tank loading chamber 3. After printing is completed, when the resin tank conveying device 5 sends the used resin tank component 4 back to the resin tank loading chamber 3, it drives the push motor 61 to move and push the unused resin tank component 4 in the resin tank loading chamber 3 onto the surface.

[0063] In this embodiment, the resin tank loading and unloading structure first pushes the resin tank component 4 in the resin tank loading chamber 3 upward until it is engaged in the engagement bracket 53 in the resin tank conveying device 5. The resin tank conveying device 5 then sends the resin tank component 4 in the engagement bracket 53 into the working area of ​​the printing device 2. After processing, the resin tank conveying device 5 sends the used resin tank component 4 to the bottom of the resin tank recycling chamber 7. The pushing device 6 then pushes another unused resin tank component 4 in the resin tank loading chamber 3 upward to abut against the resin tank component 4 in the engagement bracket 53 and pushes it into the resin tank recycling chamber 7. The unused resin tank component 4 is then engaged in the engagement bracket 53 in the resin tank conveying device 5. The resin tank conveying device 5 then sends the resin tank component 4 in the engagement bracket 53 into the working area of ​​the printing device 2, and the operation is repeated.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
