It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

As shown in fig. 1 and 2, a resin storage device 100 for photocuring 3D printing according to an embodiment of the present invention includes a resin tank 1, a storage tank 2, a first flap 3, and a second flap 4. The first flap 3 is provided on the resin tank 1 and partitions a first reservoir chamber 101 inside the resin tank 1. The first liquid storage cavity 101 is used for containing liquid resin for laser irradiation to perform photocuring 3D printing. In order to enable laser to irradiate the liquid resin in the first liquid storage cavity 101 for photocuring 3D printing, the upper end of the first liquid storage cavity 101 generally has an opening for laser irradiation, and the specific structure of the opening is set to be the prior art, which is not described herein again.

The first flap 3 described above may be provided inside the resin tank 1 (as shown in fig. 1 and 2), or constitute a part of the tank wall of the resin tank 1 itself. The first movable plate 3 is used for adjusting the volume of the first reservoir 101 when moving to different positions, so as to increase or decrease the volume of the first reservoir 101. The second movable plate 4 is arranged on the storage tank 2 and separates a closed second liquid storage cavity 201 in the storage tank 2. The second movable plate 4 may be provided inside the storing bath 2 (as shown in FIGS. 1 and 2), or constitute a part of the wall of the storing bath 2 itself. The second movable plate 4 is used for adjusting the volume of the second reservoir 201 when moving to different positions, so as to increase or decrease the volume of the second reservoir 201. Wherein the first reservoir 101 is in communication with the second reservoir 201.

In the above technical solution, as shown in fig. 1, after the photocuring 3D printing is finished, and when the residual liquid resin is in the first liquid storage cavity 101 of the resin tank 1, the positions of the first movable plate 3 and the second movable plate 4 can be adjusted, so that the volume of the first liquid storage cavity 101 is reduced, and the volume of the second liquid storage cavity 201 is increased, and since the first liquid storage cavity 101 is communicated with the second liquid storage cavity 201, the residual liquid resin in the first liquid storage cavity 101 can be extruded into the second liquid storage cavity 201 when the volume of the first liquid storage cavity 101 is reduced. Because the second liquid storage cavity 201 is of a closed structure, the second liquid storage cavity 201 can protect the liquid resin and prevent the liquid resin from being exposed in the air and losing effectiveness due to excessive moisture absorption.

As shown in fig. 2, when the photocuring 3D printing needs to be performed by using the liquid resin again, the positions of the first movable plate 3 and the second movable plate 4 can be adjusted to increase the volume of the first liquid storage cavity 101 and reduce the volume of the second liquid storage cavity 201, and the liquid resin stored inside can be extruded into the first liquid storage cavity 101 when the volume of the second liquid storage cavity 201 is reduced due to the communication between the first liquid storage cavity 101 and the second liquid storage cavity 201, so as to perform the photocuring 3D printing.

In order to realize the function of adjusting the volume of the first reservoir 101 by the first movable plate 3, the present invention further provides the following embodiments: as shown in fig. 1 and 2, the first movable plate 3 may be a lifting plate. The first flap 3 is located in the resin tank 1 and is in sealing fit with the tank wall of the resin tank 1, for example, the first flap 3 and the tank wall of the resin tank 1 can be sealed by surface fit. The first movable plate 3 divides the first reservoir chamber 101 above the first movable plate. The resin storage apparatus 100 of the present invention further includes a first driving mechanism for driving the first flap 3 to ascend. The first movable plate 3 may descend under the action of its own gravity, may also descend under the driving of the driving mechanism, and may also descend manually through pushing the first movable plate 3 to descend from the opening of the first liquid storage cavity 101, and the specific descending manner may be selected according to actual requirements. Preferably, the first flap 3 is configured as a plate that can be lowered by its own weight, so that the first flap 3 can be automatically lowered. In this example, when the first moving plate 3 is driven to ascend by the first driving mechanism, the volume of the first reservoir chamber 101 decreases; when the first movable plate 3 descends, the volume of the first reservoir chamber 101 increases.

As shown in fig. 1 and 2, the first driving mechanism may include a first airbag 5 located below the first flap 3 to push the first flap 3 to ascend by the first airbag 5. Preferably, the first flap 3 further partitions the resin tank 1 into a first accommodating cavity 102, and the first accommodating cavity 102 and the first reservoir cavity 101 are respectively located on two opposite sides of the first flap 3. The first air bag 5 can be placed in the first accommodating chamber 102, and the air inlet and outlet of the first air bag 5 are communicated with the outside through a pipeline, so that the inflation and deflation of the first air bag 5 can be controlled conveniently.

In order to realize the function of adjusting the volume of the second reservoir chamber 201 by the second movable plate 4, the present invention further provides the following embodiments: as shown in fig. 1 and 2, the second flap 4 may be a lifting flap. The second movable plate 4 is located in the storing groove 2 and is in sealing fit with the groove wall of the storing groove 2, for example, the second movable plate 4 and the groove wall of the storing groove 2 can be sealed by surface fit. The second movable plate 4 divides the second reservoir 201 above the second movable plate. The resin storage apparatus 100 of the present invention further includes a second driving mechanism for driving the second flap 4 to ascend. Wherein, the second fly leaf 4 can descend under the effect of self gravity, certainly also can descend by the drive mechanism drive, can also set up the lid through the upper end at second stock solution chamber 201, and the manual work promotes the second fly leaf 4 from the lid of opening and descends, and its concrete descending mode can be selected according to actual demand. Preferably, the second flap 4 is configured as a plate that can be lowered under the effect of its own weight, so that the second flap 4 can be automatically lowered. In this example, when the second driving mechanism drives the second movable plate 4 to ascend, the volume of the second reservoir chamber 201 is reduced; when the second movable plate 4 descends, the volume of the second reservoir chamber 201 increases.

As shown in fig. 1 and 2, the second driving mechanism may include a second airbag 6 located below the second flap 4 to push the second flap 4 to ascend by the second airbag 6. Preferably, the second movable plate 4 is further divided into a second accommodating cavity 202 in the storage tank 2, and the second accommodating cavity 202 and the second reservoir 201 are respectively located on two opposite sides of the second movable plate 4. The second airbag 6 can be placed in the second accommodating chamber 202, and the air inlet and outlet of the second airbag 6 are communicated with the outside through a pipeline, so that the inflation and deflation of the second airbag 6 can be controlled conveniently.

As shown in fig. 1 and 2, when the aforementioned resin storage apparatus 100 includes both the first air bag 5 and the second air bag 6, the resin storage apparatus 100 may further include an inflation mechanism 9, a first three-way valve 7, and a second three-way valve 8. The inflation mechanism 9 may be an air compressor or the like. Both the first three-way valve 7 and the second three-way valve 8 have an inlet, a first air outlet and a second air outlet. Wherein, the first export of first three-way valve 7 and second three-way valve 8 both is connected with the inflation inlet of inflating mechanism 9, and the import of first three-way valve 7 is connected with the business turn over gas port of first gasbag 5, and the import of second three-way valve 8 is connected with the business turn over gas port of second gasbag 6. In this example, as shown in fig. 1, when the photo-curing 3D printing is finished and the liquid resin remains in the first reservoir 101 of the resin tank 1, the first three-way valve 7 and the second three-way valve 8 may be adjusted such that the inlet of the first three-way valve 7 is communicated with the first outlet and the inlet of the second three-way valve 8 is communicated with the second outlet. Because the second outlet of the second three-way valve 8 is directly communicated with the atmosphere, the second airbag 6 can be deflated outwards without being supported by the second airbag 6, and the second movable plate 4 can descend under the action of self gravity, so that the volume of the second liquid storage cavity 201 is increased. At this time, the inflating mechanism 9 is started, the inflating mechanism 9 inflates the first air bag 5 through the first three-way valve 7, the first air bag 5 pushes the first movable plate 3 to ascend, the volume of the first liquid storage cavity 101 is reduced, and the liquid resin remained in the first liquid storage cavity 101 is squeezed and sent to the second liquid storage cavity 201 of the storage tank 2.

As shown in fig. 2, when the photo-curing 3D printing needs to be performed again using the liquid resin, the first three-way valve 7 and the second three-way valve 8 may be adjusted such that the inlet of the first three-way valve 7 is communicated with the second outlet and the inlet of the second three-way valve 8 is communicated with the first outlet. Because the second outlet of the first three-way valve 7 is directly communicated with the atmosphere, the first air bag 5 can be deflated outwards, and the first movable plate 3 can descend under the action of self gravity without being supported by the first air bag 5, so that the volume of the first liquid storage cavity 101 is increased. At this time, the inflation mechanism 9 is started, the inflation mechanism 9 inflates the second air bag 6 through the second three-way valve 8, the second air bag 6 pushes the second movable plate 4 to ascend, the volume of the second liquid storage cavity 201 is reduced, and the liquid resin stored in the second liquid storage cavity 201 is squeezed into the first liquid storage cavity 101.

In the above example, the inflation mechanism 9, the first three-way valve 7 and the second three-way valve 8 cooperate with each other to perform the inflation and deflation operations on the first air bag 5 and the second air bag 6, so as to adjust the volume of the first reservoir 101 and the second reservoir 201, without designing two sets of mechanisms to perform the inflation and deflation operations on the first air bag 5 and the second air bag 6, thereby reducing the structural cost of the present invention.

In a specific application example, the first three-way valve 7 and the second three-way valve 8 may be two-position three-way solenoid valves. The resin storage device 100 further includes a controller for controlling the first three-way valve 7, the second three-way valve 8, and the inflation mechanism 9, so that when the resin storage device 100 is in the first state, the inlet of the first three-way valve 7 is communicated with the first outlet of the first three-way valve 7, the inlet of the second three-way valve 8 is communicated with the second outlet of the second three-way valve 8, and the inflation mechanism 9 performs inflation operation; and when the resin storage apparatus 100 is in the second state, the inlet of the first three-way valve 7 is communicated with the second outlet of the first three-way valve 7, the inlet of the second three-way valve 8 is communicated with the first outlet of the second three-way valve 8, and the inflation mechanism 9 performs inflation operation. Specifically, as shown in fig. 1, when the resin storage apparatus 100 is in the first state, the first flap 3 is lifted, and the second flap 4 is lowered, so that the liquid resin remaining in the first reservoir 101 is pushed into the second reservoir 201 of the storage tank 2. As shown in fig. 2, in the second state, the first flap 3 descends and the second flap 4 ascends, so that the liquid resin stored in the second reservoir chamber 201 is pushed into the first reservoir chamber 101. The specific working process can refer to the corresponding description above, and is not described herein again.

The controller can be a PLC or a processor. The controller is matched with the two-position three-way electromagnetic valves, so that automatic control over inflation and deflation of the first air bag 5 and the second air bag 6 can be realized, and the automatic control device has the effect of saving manpower.

Further, as shown in fig. 1 and 2, a filter 10 may be disposed between the first reservoir 101 and the second reservoir 201 to prevent impurities in the first reservoir 101 from flowing into the second reservoir 201, which may cause deterioration of the liquid resin during long-term storage in the second reservoir 201.

Further, as shown in fig. 1 and fig. 2, both the first liquid storage cavity 101 and the second liquid storage cavity 201 have discharge ports, and the two discharge ports are provided with discharge valves 12 and communicated to the liquid collecting barrel 13 through a pipeline, so as to conveniently discharge the liquid resin in the two liquid storage cavities.

As shown in fig. 1 and fig. 2, the second liquid storage chamber 201 may further be provided with a material supplementing port 11 to facilitate material supplementing into the second liquid storage chamber 201, so as to solve the problem of fluid supplementing balance, and always maintain the liquid level of the first liquid storage chamber 101 on the printing surface, thereby reducing the trouble of adding resin for an operator.

The present invention also provides a photo-curing 3D printer, which may include any one of the above-described resin storage devices 100 for photo-curing 3D printing.

The photocuring 3D printer of the invention can send the liquid resin remained in the first liquid storage cavity 101 of the resin tank 1 to the second liquid storage cavity 201 of the storage tank 2 for storage due to the arrangement of the resin storage device 100, and the second liquid storage cavity 201 can protect the liquid resin due to the closed structure of the second liquid storage cavity 201, so that the liquid resin is prevented from being exposed in the air and losing efficacy due to excessive moisture absorption.
