At present, the fields such as micro-projection, near-eye display, wearable and the like all seek products with small volume and high imaging quality, and undoubtedly have strict requirements on the processing and assembly of the products. The beam splitter prisms adopted by the micro products have high requirements on surface precision, angle precision, smoothness, stress magnitude and the like, so that in the process of gluing the beam splitter prisms, the attention of people is gradually paid to how to improve the gluing precision and ensure higher gluing yield. The utility model provides a prism veneer device, its high accuracy, the high yields that can guarantee the veneer prism.

Referring to fig. 1 to 8 of the drawings, a prism gluing device according to an embodiment of the present invention is illustrated. Specifically, the prism gluing device 1 is used for gluing a first prism 51 to be glued and a second prism 52 to be glued, wherein the prism gluing device 1 comprises a base 10, a limiting component 20 and a sliding support element 30. The base 10 has a receiving groove 100 for supportingly receiving the first prism 51 to be glued, so that the first inclined surface 511 of the first prism 51 to be glued faces upward. The sliding support element 30 is slidably disposed above the accommodating groove 100 of the base 10, and is used for slidably supporting the second prism to be glued 52, so that the second prism to be glued 52 is located above the accommodating groove 100 of the base 10. The limiting component 20 is positioned on the base 10, and is used for limiting the first prism to be glued 51 and the second prism to be glued 52, so that the second inclined surface 521 of the second prism to be glued 52 is aligned with the first inclined surface 511 of the first prism to be glued 51 in a face-to-face manner, and when the sliding support element 30 slides away from the accommodating groove 100 of the base 10, the sliding support element 30 is used for removing the support of the second prism to be glued 52, so that the second prism to be glued 52 naturally falls to the first prism to be glued 51 to complete gluing.

It is noted that, since the first prism to be glued 51 and the second prism to be glued 52 are generally implemented as right-angle prisms, in order to stably support the first prism to be glued 51 to ensure that the first inclined surface 511 of the first prism to be glued 51 located in the accommodating groove 100 of the base 10 faces upward, the accommodating groove 100 of the base 10 of the prism gluing device 1 of the present invention has mutually perpendicular side wall surfaces 101 so that the side wall surfaces 101 of the accommodating groove 100 can face-to-face contact with the right-angle surface 512 of the first prism to be glued 51 to stably support the first prism to be glued 51.

Preferably, in the above embodiment of the present invention, as shown in fig. 2 and fig. 3, the receiving groove 100 has a V-shaped structure, so that the side wall surface 101 of the receiving groove 100 can contact the right-angle surface 512 of the first prism 51 to be glued to the maximum extent, so as to reduce the pressure applied to the right-angle surface 512 of the first prism 51 to be glued, and help to protect the right-angle surface 512 of the first prism 51 to be glued.

According to the above embodiment of the present invention, as shown in fig. 2 and fig. 6, the limiting component 20 of the prism gluing device 1 may include a first limiting component 21, a second limiting component 22 and a third limiting component 23, wherein the first limiting component 21, the second limiting component 22 and the third limiting component 23 are respectively positioned on the base 10 and respectively located on three sides of the receiving groove 100 to limit the positions of the first and second to-be-glued prisms 51 and 52 from three directions, so as to ensure that the second inclined plane 521 of the second to-be-glued prism 52 falls face to face and naturally down to the first inclined plane 511 of the first to-be-glued prism 51, thereby completing the gluing process.

For example, as shown in fig. 6 and 7, the first limiting member 21 is fixedly positioned on the base 10 to be located at the front side of the accommodating groove 100, so as to limit the positions of the first and second prisms 51 and 52 to be glued from the front side of the accommodating groove 100; the second limiting member 22 is fixedly positioned on the base 10 to be located at the left side of the accommodating groove 100, and is used for limiting the positions of the first and second to-be-glued prisms 51 and 52 from the left side of the accommodating groove 100. Specifically, the third stopper 23 is detachably mounted on the base 10 to be located at the rear side of the receiving groove 100, and is used for limiting the positions of the first and second to- be-glued prisms 51 and 52 from the rear side of the receiving groove 100. Meanwhile, the accommodating groove 100 extends from the front side of the base 10 to the rear side of the base 10, so that the first limiting member 21 and the third limiting member 23 are respectively located at the front side and the rear side of the accommodating groove 100, and the first to-be-glued prism 51 is prevented from sliding back and forth in the accommodating groove 100.

It should be noted that, as shown in fig. 3, since the third limiting member 23 is detachably mounted on the base 10, and the third limiting member 23 is located at the rear side of the accommodating groove 100, when the third limiting member 23 is detached from the base 10, the first prism to be glued 51 can slide into the accommodating groove 100 from the rear side of the accommodating groove 100, so as to prevent the first prism to be glued 51 from colliding when being placed into the accommodating groove 100, and protect the first prism to be glued 51 from being damaged; when the third limiting member 23 is mounted on the base 10, the first prism 51 to be glued is limited in the accommodating groove 100 by the first limiting member 21, the second limiting member 22 and the third limiting member 23, so as to stably maintain the first prism 51 to be glued in the accommodating groove 100.

In addition, the third limiting member 23 can be, but not limited to, detachably mounted on the base 10 by means of magnetic attraction, that is, the third limiting member 23 and the base 10 can be made of corresponding magnetic materials, respectively, so as to magnetically fix the third limiting member 23 to the base 10. Of course, the third limiting member 23 can also be detachably mounted on the base 10 by means of screws, nesting, and the like; the first and second limiting members 21 and 22 may be fixed to the base 10 by screwing, welding, gluing, integrally connecting, or the like.

It should be noted that, as shown in fig. 6 and 7, the sliding support element 30 of the prism gluing device 1 is slidably mounted on the third limiting member 23, so that after the third limiting member 23 is mounted on the base 10, the sliding support element 30 is located above the accommodating groove 100 of the base 10 to slidably support the second prism to be glued 52, so that the second inclined surface 521 of the second prism to be glued 52 is located above the first inclined surface 511 of the first prism to be glued 51 in a face-to-face manner. When the sliding support element 30 slides away from the receiving groove 100, the second prism 52 to be glued naturally falls to the first prism 52 to be glued due to the loss of the support of the sliding support element 30, so that the second inclined surface 521 of the second prism 52 to be glued is attached to the first inclined surface 511 of the first prism 51 to be glued face to face, so as to realize the corresponding gluing operation.

It can be understood that when the sliding support element 30 slides away from the receiving groove 100, the third limiting member 23 will limit the position of the second prism to be glued 52, so as to prevent the second prism to be glued 52 from being carried by the sliding support element 30 to deviate from the first prism to be glued 51, which helps to ensure that the second inclined surface 521 of the second prism to be glued 52 and the first inclined surface 511 of the first prism to be glued 51 are always aligned face to face.

Preferably, as shown in fig. 2, the third limiting member 23 is provided with at least one sliding slot 231, and the sliding support element 30 includes at least one sliding support arm 31, wherein the sliding support arm 31 of the sliding support element 30 is adapted to the sliding slot 231 of the third limiting member 23, so that while the sliding support arm 31 can slide in the sliding slot 231 of the third limiting member 23, an end of the sliding support arm 31 can protrude out of the third limiting member 23, so as to support the second prism 52 to be glued on the accommodating slot 100.

More preferably, as shown in fig. 2, the sliding support arm 31 of the sliding support element 30 extends in a uniform cross section, so that the sliding support element 30 can be slidably assembled to the third limiting member 23 or slidably disassembled from the third limiting member 23, which helps to reduce the difficulty of assembling the prism gluing device 1.

Further, as shown in fig. 2 and 6, the third limiting member 23 may include a mounting portion 232 and a limiting portion 233, wherein the mounting portion 232 of the third limiting member 23 is mounted on the base 10, and the sliding slot 231 is disposed on the mounting portion 232; the limiting portion 233 of the third limiting member 23 integrally extends forward from the mounting portion 232 to abut against a side surface of the first prism 51 to be glued to limit the position of the first prism 51 to be glued. Meanwhile, when the sliding support element 30 slides away from the accommodating groove 100 along the sliding groove 231 of the third limiting member 23, the limiting portion 233 of the third limiting member 23 abuts against the side surface of the second prism to be glued 52, so as to prevent the second prism to be glued 52 from being driven by the supporting arm 32 of the sliding support element 30 to deviate from the first prism to be glued 51, and ensure that the first and second prisms to be glued 51, 52 are always aligned with each other.

Illustratively, as shown in fig. 2 and 7, the third limiting member 23 has two sliding grooves 231, and the sliding grooves 231 are respectively located at the left and right sides of the mounting portion 232 of the third limiting member 23, wherein the cross section of the limiting portion 233 is smaller than that of the mounting portion 232, and the limiting portion 233 integrally extends forward from the middle of the mounting portion 232 to form the third limiting member 23 having a zigzag structure. The slide supporting arms 31 of the slide supporting member 30 are disposed at intervals, wherein when the slide supporting arms 31 slide in the sliding slots 231 of the third limiting member 23, the slide supporting arms 31 of the slide supporting member 30 will be located at both sides of the limiting portion 233 of the third limiting member 23 and protrude forward from the limiting portion 233, so as to stably support the second prism 52 to be glued. Of course, in other examples of the present invention, the sliding groove 231 of the third limiting member 23 may be implemented as a through groove penetrating through the mounting portion 232 and the limiting portion 233, and it can still be ensured that the sliding support arm 31 of the sliding support element 30 slides in the sliding groove 231, and protrudes from the limiting portion 233 to slidably support the second prism 52 to be glued.

Thus, when the first prism 51 to be glued and the second prism 52 to be glued are glued, the first prism 51 to be glued is placed in the accommodating groove 100 of the base 10, so that two adjacent edges (such as the front edge and the left edge) of the inclined surface 511 of the first prism 51 to be glued are respectively tightly attached to the first limiting member 21 and the second limiting member 22, so as to ensure that the first prism 51 to be glued is stable in the accommodating groove 100, and the first inclined surface 511 of the first prism 51 to be glued is upward (as shown in fig. 3); after a proper amount of glue (e.g., uv curable glue) is dropped on the first inclined surface 511 of the first prism 51 to be glued, the side without the back glue of the light splitting element 40 (e.g., polarizer) faces downward, and is horizontally placed on the first inclined surface 511 of the first prism 51 to be glued (as shown in fig. 4). In this way, pressure is applied from the left side and the front side of the light splitting element 40 (e.g., the portions close to the first and second stoppers 21 and 22), so that the glue between the light splitting element 40 and the first prism 51 to be glued naturally overflows to achieve uniform post-curing, thereby achieving the effect of gluing the light splitting element 40 to the first prism 51 to be glued. It is understood that the glued side of the light splitting element 40 faces upwards to glue the second prism to be glued 52.

Then, the third limiting member 23 with the sliding support element 30 mounted thereon is mounted on the base 10, and the end of the sliding support arm 31 of the sliding support element 30 is located above the first inclined surface 511 of the first prism to be glued 51 placed in the accommodating groove 100 (as shown in fig. 5); next, the second prism to be glued 51 is placed on the slide brace arm 31 of the slide brace element 30, and under the action of the first, second and third stoppers 21, 22 and 23, the first prism to be glued 51 and the second prism to be glued 52 are aligned in a face-to-face manner (as shown in fig. 6); finally, sliding the sliding support element 30 slowly to retract the sliding support arm 31 to the third stopper 23, the second prism to be glued 52 will naturally fall on the first inclined surface 511 of the first prism to be glued 51, and the glued surface of the light splitting element 40 is finished (as shown in fig. 7). It can be understood that when the third limiting member 23 is installed on the base 10, a certain gap exists between the sliding arm 31 of the sliding supporting element 30 and the first inclined surface 511 of the first prism 51 to be glued, so as to prevent the sliding supporting element 30 from contacting the upper surface glue layer of the light splitting element 40 and adversely affecting the gluing quality.

It is worth noting that, in the above example of the present invention, since the first and second locating parts 21 and 22 are respectively tightly attached to the front side and the left side of the first inclined plane 511 of the first prism 51 to be glued, so that the back side and the right side of the first inclined plane 511 of the first prism 51 to be glued are left with sufficient operating space and glue overflow space, the prism gluing device 1 of the present invention can realize the gluing between the independent light splitting element 40 (such as an independent polarization light splitting film or a metal wire grating film, etc.) and the first prism 51 to be glued, so as to adopt the light splitting element 40 with better light splitting performance as required.

In other examples of the present invention, the splitting element 40 can also be implemented as a splitting film plated on the first inclined plane 511 of the first prism 51 to be glued, so that the splitting element 40 is not glued on the first prism 51 to be glued by the prism gluing device 1, but the second prism 52 to be glued is directly glued on the first prism 51 to be glued on which the splitting film is plated, so as to obtain a high-quality splitting prism. In other words, the prism gluing device 1 of the present invention can be free from the limitation of the existence form of the light splitting element 40, and not only can the gluing between the first prism 51 to be glued and the second prism 52 to be glued, which are plated with the light splitting element 40, be realized, but also the independent gluing between the light splitting element 40 and the first and second prisms 51 and 52 to be glued can be realized, so as to adopt the light splitting element 40 with better light splitting performance.

Furthermore, although micro-projection, near-eye display, wearable, etc. devices are pursuing smaller size and lighter weight, the size of the beam splitting prism required for different models or types of devices will also be different, that is, the size of the first and second prisms 51, 52 to be glued will be different. Therefore, in order to satisfy the gluing between the first and second prisms 51, 52 to be glued of different sizes, fig. 9 shows a variant embodiment of the prism gluing device 1 according to the above-described embodiment of the present invention, wherein the third limiting member 23 of the prism gluing device 1 can be adjustably mounted to the base 10 to adjust the mounting position of the third limiting member 23 according to the length size of the first prism 51 to be glued, so that the distance between the first limiting member 21 and the third limiting member 23 is equal to the length of the first prism 51 to be glued. In other words, the prism gluing device 1 can be changed along with the size change of the first prism 51 to be glued so as to complete the gluing of the light splitting prisms (i.e. the first and second prisms 51 and 52 to be glued) with various sizes, and is particularly suitable for gluing micro prisms in different types of micro-projection, near-eye display, wearable field and other equipment.

In particular, as shown in fig. 9, in this variant embodiment of the present invention, the receiving groove 100 may have a Y-shaped structure to prevent the right-angled edge of the first prism to be glued 51 from contacting the wall surface of the receiving groove 100 (i.e., from contacting the base 10) while ensuring that the side wall surface 101 of the receiving groove 100 contacts the right-angled surface 512 of the first prism to be glued 51 face to face, so as to prevent the right-angled edge of the first prism to be glued 51 from being damaged by the collision.

Meanwhile, as shown in fig. 9, the third limiting member 23 further includes a sliding portion 234, wherein the sliding portion 234 integrally extends forward from the mounting portion 232, and the sliding portion 234 is adapted to the receiving groove 100, so that the sliding portion 234 can adaptively extend into the receiving groove 100, so as to slidably mount the third limiting member 23 on the base 10, and further slide the sliding portion 234 of the third limiting member 23 back and forth along the receiving groove 100, so as to adjust the distance between the third limiting member 23 and the first limiting member 21, thereby facilitating to complete the gluing between the first and second prisms 51 and 52 to be glued in various sizes.

For example, as shown in fig. 9, the receiving groove 100 of the base 10 has a receiving space 110 and a sliding-mounting space 120, wherein the sliding-mounting space 120 extends downward from the receiving space 110 in a communicating manner to form the receiving groove 100 with a Y-shaped structure. The sliding part 234 of the third limiting member 23 is located below the limiting part 233, and the sliding part 234 is adapted to the sliding space 120 of the receiving groove 100, so that the sliding part 234 can slide in the sliding space 120 as a sliding arm, and the third limiting member 23 is then slidably mounted on the base 10, which facilitates sliding the third limiting member 23 conveniently according to the size of the first and second prisms 51 and 52 to be glued, and is suitable for gluing between the first and second prisms 51 and 52 to be glued of any size.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
