Description

Technical Field

[0001] This invention relates to the field of 3D printer technology, and more particularly to a 3D printer optical engine angle adjustment structure and a 3D printer. Background Technology

[0002] The optical engine of a 3D printer emits light necessary for resin curing. Changing the pattern of the emitted light enables 3D printing. The optical engine is connected to a lifting mechanism via a connecting structure, allowing for its movement. During the curing process, it's crucial to ensure the light emitted by the optical engine is perpendicular to the resin to guarantee printing accuracy. To adjust the angle of the optical engine, an angle-adjustable connecting structure is required. However, current technology uses numerous screws for fixing, which is inconvenient. Summary of the Invention

[0003] Therefore, it is necessary to provide a 3D printer optical engine angle adjustment structure and a 3D printer that can achieve adjustable optical engine angle while reducing the number of screws used.

[0004] This invention provides a 3D printer optical engine angle adjustment structure, comprising:

[0005] A first connector, wherein a first circular hole and a first arc hole are provided on the first connector, and the first arc hole and the first circular hole are not concentric;

[0006] The second connector has a second circular hole and a second arc hole. The second arc hole is not concentric with the second circular hole, while the first circular hole and the second circular hole are concentric. The width of the second arc hole is equal to the width of the first arc hole.

[0007] A first screw, the first screw passing through the first circular hole and the second circular hole;

[0008] The second screw has a width equal to the diameter of the first arc hole, and the second screw passes through both the first arc hole and the second arc hole.

[0009] Wherein, when the first connector rotates around the center of the first circular hole such that the first connector is at an angle relative to the second connector, the first circular hole and the second circular hole at least intersect.

[0010] Furthermore, when the first connector rotates around the center of the first circular hole so that the first connector is at a first preset angle relative to the second connector, the first circular hole and the second circular hole are concentric.

[0011] Furthermore, the centerline of the first arc hole passes through the first circular hole, and the centerline of the second arc hole passes through the second circular hole. When the first arc hole and the second arc hole are concentric, the centerline of the first arc hole coincides with the centerline of the second arc hole.

[0012] Furthermore, when the first arc hole and the second arc hole are concentric, the first arc hole and the second arc hole coincide.

[0013] Furthermore, the first circular hole is located between the center of the first arc-shaped hole and the first arc-shaped hole.

[0014] The present invention also provides a 3D printer, including an optical engine, wherein the optical engine is connected to the first connecting member in the optical engine angle adjustment structure of the 3D printer.

[0015] Compared to the prior art, the beneficial effects of the present invention are as follows: The present invention allows the first connecting member to rotate around the center of the circular hole relative to the second connecting member by passing the first screw through the first circular hole and the second circular hole. The first circular hole and the second circular hole intersect. Since the diameter of the second screw is equal to that of the first circular hole and the second circular hole, after the second screw passes through the intersection, the inner surfaces of the first circular hole and the second circular hole jointly restrict the second screw, making the second screw fixed at the intersection point and unable to move. This fixes the angle between the first connecting member and the second connecting member, allowing the optical engine to emit perpendicular light. Attached Figure Description

[0022] A specific embodiment of the present invention provides an angle adjustment structure 200 for a 3D printer optical engine 100, such as... Figure 1-3 As shown, the adjustment structure 200 includes a first connector 10, a second connector 20, a first screw 30, and a second screw 40.

[0023] The first connector 10 includes two oppositely arranged first connecting plates 11, and the second connector 20 includes two oppositely arranged second connecting plates 21, with one first connecting plate 11 paired with one second connecting plate 21.

[0024] The first connecting plate 11 has a first circular hole 111 and a first arc-shaped hole 112, the first arc-shaped hole 112 being non-concentric with the first circular hole 111. The second connecting plate 21 has a second circular hole 211 and a second arc-shaped hole 212, the second arc-shaped hole 212 being non-concentric with the second circular hole 211, the first circular hole 111 and the second circular hole 211 being concentric, and the width of the second arc-shaped hole 212 being equal to the width of the first arc-shaped hole 112.

[0025] The first screw 30 passes through the first circular hole 111 and the second circular hole 211; the second screw 40 passes through the first arc hole 112 and the second arc hole 212, and the width of the first arc hole 112 is equal to the diameter of the second screw 40.

[0026] like Figure 3 As shown, when the first connector 10 rotates around the center of the first circular hole 111 such that the first connector 10 forms an angle with respect to the second connector 20, the first circular hole 112 and the second circular hole 212 intersect at least once.

[0027] In this embodiment, such as Figure 2 As shown, when the first connector 10 rotates around the center of the first circular hole 111 such that the first connector 10 forms a preset angle relative to the second connector 20 ( Figure 2 When the optical mechanism is horizontal, the center 113 of the first arc hole 112 coincides with the center 213 of the second arc hole 212, that is, the first arc hole 112 and the second arc hole 212 are concentric.

[0028] Furthermore, when the center line L1 of the first arc-shaped hole 112 passes through the first circular hole 111, and the center line L2 of the second arc-shaped hole 212 passes through the second circular hole 211, and the first arc-shaped hole 112 and the second arc-shaped hole 212 are concentric, the center line L1 of the first arc-shaped hole 112 coincides with the center line L2 of the second arc-shaped hole 212. Furthermore, when the first arc-shaped hole 112 and the second arc-shaped hole 212 are concentric, the first arc-shaped hole 112 coincides with the second arc-shaped hole 212. Furthermore, the first circular hole 111 is located between the center of the first arc-shaped hole 112 and the first arc-shaped hole 112, and the second circular hole 211 is located between the center of the second arc-shaped hole 212 and the second arc-shaped hole 212.

[0029] In this invention, the first screw 30 passes through the first circular hole 111 and the second circular hole 211, allowing the first connector 10 to rotate relative to the second connector 20 around the center of the circular hole. The first circular hole 112 intersects with the second circular hole 212. Since the diameter of the second screw 40 is equal to that of the first circular hole 112 and the second circular hole 212, after the second screw 40 passes through the intersection, the inner surfaces of the first circular hole 112 and the second circular hole 212 form a similar prism shape. The four faces S1, S2, S3, and S4 of the prism restrict the second screw 40, fixing it at the intersection point and preventing it from moving. This fixes the angle between the first connector 10 and the second connector 20, allowing the optical engine 100 to emit vertical light.
