In the existing technical field of 3D printing, in order to improve the utilization rate of an optical device, the optical device can be moved to different stations to realize multi-station printing of the optical device.
In order to improve the accuracy of the moving distance of the optical device in the moving process, so that the optical device works in different working positions, in the existing scheme, a high-precision driving element is adopted to drive the optical device, for example, a high-precision motor and a high-precision lead screw guide rail mode or a mode of additionally arranging a grating ruler is adopted to ensure the accuracy of the movement of the optical device. However, such a high-precision driving element is high in cost, so that it is difficult to reduce the production cost of the 3D printer. For this reason, researchers think that the optical device and the positioning seat are positioned by means of, for example, two positioning surfaces attached to each other, so that the optical device can reach a specified working position, and the production cost of the optical moving module is reduced by the positioning means.

The supporting member 200 of the optical device is a first working position of the optical device when being attached to the first positioning base 300, and is a second working position when being attached to the second positioning base 400. The optical device support 200 is moved to be attached to the first positioning seat 300 and the second positioning seat 400, and the optical device can work at different working positions through a surface-to-surface positioning mode.
Specifically, the table 100 is provided with a driving module 110 capable of reciprocating in a first direction; the optical device or the supporting member 200 of the optical device is disposed on the worktable 100 and is guided by the driving module 110 to reciprocate along a first direction, which is the direction pointed by the arrow a in fig. 1, and the supporting member 200 of the optical device includes an a1 positioning surface 210 and an a2 positioning surface 220 which are disposed opposite to each other in the first direction; the first positioning seat 300 and the second positioning seat 400 are oppositely arranged along a first direction, the supporting member 200 of the optical device is located between the first positioning seat 300 and the second positioning seat 400, wherein the first positioning seat 300 includes a B positioning surface 310, the B positioning surface 310 of the first positioning seat faces the a1 positioning surface 210 of the supporting member 200 of the optical device and is parallel to the a1 positioning surface 210, the second positioning seat 400 includes a C positioning surface 410, and the C positioning surface 410 of the second positioning seat 400 faces the a2 positioning surface 220 of the supporting member 200 of the optical device and is parallel to the a2 positioning surface 220 of the supporting member 200 of the optical device. It should be noted that the a1 locating surface 210 and the a2 locating surface 220 may be parallel to each other and perpendicular to the first direction; the drive module 110 may include an air cylinder or a timing belt or linear bearings.

When the positioning surface is used for positioning, the driving module 110 does not need to use a high-precision positioning element, and only needs that the driving module 110 can drive the supporting member 200 of the optical device to reciprocate along the first direction, so that the a1 positioning surface 210 is attached to the B positioning surface 310, and the a2 positioning surface 220 is attached to the C positioning surface 410, so that the supporting member 200 of the optical device reaches the corresponding working position. Compared with the existing scheme, the scheme realizes the positioning between the support piece 200 of the optical device and the first positioning seat 300 and the second positioning seat 400 through the positioning mode pair of the positioning surfaces, so that the driving module 110 does not need to select a high-precision driving element with higher cost, and further the production cost of the optical mobile module can be reduced.
In order to prevent the a1 positioning surface 210 of the supporting member 200 of the optical device from moving in the horizontal direction relative to the B positioning surface 310 of the first positioning seat after the B positioning surface 310 of the first positioning seat and the a1 positioning surface 210 of the supporting member 200 of the optical device are positioned, thereby affecting the positioning accuracy between the supporting member 200 of the optical device and the first positioning seat 300, a researcher may think of providing a positioning shaft and a positioning hole to limit the movement of the supporting member 200 of the optical device relative to the first positioning seat 300. Specifically, as shown in fig. 2, 3 and 4, the first positioning seat 300 is provided with a first positioning hole 311 on the B positioning surface 310, and the first positioning shaft 211 is provided on the a1 positioning surface 210 of the support 200 of the optical device, and the first positioning shaft 211 can be engaged with the first positioning hole 311.

Similarly, in order to prevent the support 200 of the optical device from rotating relative to the second positioning socket 400 after the C positioning surface 410 of the second positioning socket 400 and the a2 positioning surface 220 of the support 200 of the optical device are positioned, researchers also adopt a positioning shaft and a positioning hole. Specifically, referring to fig. 1 and 3, a second positioning hole 411 is disposed on the C positioning surface 410 of the second positioning socket 400, and a second positioning shaft 221 is disposed on the a2 positioning surface 220 of the support 200 of the optical device, wherein the second positioning shaft 221 can be engaged with the second positioning hole 411.
Furthermore, in order to prevent the supporting member 200 of the optical device from rotating relative to the first positioning base 300, researchers also use a positioning block and a positioning slot to limit the rotation. Specifically, referring to fig. 2, 3 and 4, a first positioning groove 312 is further provided on the B positioning surface 310 of the first positioning seat 300, and a first positioning block 212 is provided on the a1 positioning surface 210 of the support 200 of the optical device, wherein the first positioning block 212 is capable of being engaged with the first positioning groove 312. When the a1 locating surface 210 of the support 200 of the optical device is attached to the B locating surface 310 of the first locating seat 300, the first locating shaft 211 is inserted into the first locating hole 311, the first locating block 212 is inserted into the first locating slot, through the cooperation of the first locating shaft 211 and the first locating hole 311, the cooperation of the first locating block 212 and the first locating slot 312, when the support 200 of the optical device can be limited to move relative to the first locating seat 300, the support 200 of the optical device can be limited to rotate relative to the first locating seat 300. In this embodiment, the first positioning groove 312 may extend to an edge of the B positioning surface 310 to facilitate machining of the first positioning groove 312.
Similarly, in order to prevent the supporting member 200 of the optical device from rotating relative to the second positioning seat 400, the researchers also use a positioning block and a positioning groove to limit the rotation. Specifically, as described with reference to fig. 1 and 3, a second positioning groove 412 is further disposed on the C positioning surface 410 of the second positioning seat 400, and a second positioning block 222 is disposed on the a2 positioning surface 220 of the support 200 of the optical device, and the second positioning block 222 can be matched with the second positioning groove 412.

Taking the adsorption module 313 as an example of an electromagnet, when the optical device or the supporting member 200 of the optical device is close to the first positioning seat 300 or the second positioning seat 400, the electromagnet is powered on, the optical device or the supporting member 200 of the optical device can be adsorbed, and the optical device or the supporting member 200 of the optical device has magnetism; when the optical device supporting member 200 is far away from the first positioning seat 300 or the second positioning seat 400, the electromagnet is powered off and does not attract the optical device or the optical device supporting member 200.
The utility model further provides a 3D printer which comprises the optical moving module. When the optical moving module is adopted in the utility model, the supporting member 200 of the optical device can be accurately positioned in the first positioning seat 300 and the second positioning seat 400, and meanwhile, the driving module 110 with lower cost can be used to reduce the production cost of the 3D printer.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
