Description

Technical Field

[0002] Optical components are widely used in various industries and are in huge demand. In addition, most optical components require gluing two or more optical components together during production. The traditional centering method during gluing is to manually place the two optical components in a gluing jig, and use the jig's own limited accuracy to achieve the purpose of centering before proceeding to the next step of gluing. This operation not only has low centering accuracy, high labor costs, and low production efficiency, but also relies on the jig's own limited accuracy to achieve centering. It is inevitable that rotation or displacement will occur, affecting the center of the optical axis and making it impossible to adjust the centering of the optical component, and the yield rate cannot be guaranteed.

[0042] Preferably, the first clamping jig 11 , the second clamping jig 20 , the third clamping jig 30 and the lifting support 40 form an E-shape.

[0043] Specifically, taking the example that each of the first clamping jig 11, the second clamping jig 20 and the third clamping jig 30 has one, the first clamping jig 11, the second clamping jig 20 and the third clamping jig 30 are arranged parallel to each other, and the first clamping jig 11 is fixedly arranged on the base 10, and the second clamping jig 20 and the third clamping jig 30 are connected by a lifting bracket 40, wherein one end of the lifting bracket 40 is fixedly connected to the base 10, and the first clamping jig 11, the second clamping jig 20, the third clamping jig 30 and the lifting bracket 40 roughly form an E shape.

In this embodiment, it is preferred that the first clamping jig 11 and the second clamping jig 20 are of the same size and shape, and the third clamping jig 30 is of the same size as the second clamping jig 20, which helps to improve the gluing efficiency.

[0044] Preferably, a plurality of first vacuum holes are provided at the bottom of the first containing tank, and the plurality of first vacuum holes are evenly distributed; a plurality of second vacuum holes are provided at the bottom of the second containing tank, and the plurality of second vacuum holes are evenly distributed, and both the first vacuum holes and the second vacuum holes are connected to the vacuum generator 50.

[0045] Preferably, the first accommodating groove and the second accommodating groove are in the shape of rectangular grooves, triangular prism grooves, or circular grooves.

[0046] Preferably, the first accommodating groove and the second accommodating groove have the same or different shapes.

[0047] Specifically, the first clamping jig 11 and the second clamping jig 20 are provided with a receiving groove on the opposite sides, that is, the first clamping jig 11 is provided with a first receiving groove on the side facing the second clamping jig 20, and the second clamping jig 20 is provided with a second receiving groove on the side facing the first clamping jig 11. The first receiving groove is used to receive the first optical element 12, and the second receiving groove is used to receive the second optical element 22. The first optical element 12 and the second optical element 22 can be the same or different. The shapes and sizes of the first receiving groove and the second receiving groove are set according to the shapes and sizes of the first optical element 12 and the second optical element 22 to adapt to the gluing of optical elements of different sizes and shapes. For example, the first optical element 12 and the second optical element 22 are both transparent semicircular optical elements, and the first receiving groove and the second receiving groove can be set to a semicircular shape. Generally, the size of the first receiving groove is slightly larger than the first optical element 12, and the size of the second receiving groove is slightly larger than the second optical element 22, so as to accommodate and fix the optical elements. For example, if the first optical element 12 is a triangular prism and the second optical element 22 is a rectangular glass, the first receiving groove is set as a triangular prism, the side of the triangular prism to be bonded faces the second clamping jig 20, and the second receiving groove is set as a rectangle.

[0048] A plurality of first vacuum holes are provided in the first receiving groove, and a plurality of second vacuum holes are provided in the second receiving groove. The plurality of first vacuum holes are connected to the exhaust pipe of the vacuum generator 50 from the bottom of the first receiving groove to the side wall of the first receiving jig, and the plurality of second vacuum holes are connected to the exhaust pipe of the vacuum generator 50 from the bottom of the second receiving groove to the side wall of the second receiving jig. The first optical element 12 is fixed in the first receiving groove by negative pressure, and the second optical element 22 is fixed in the second receiving groove. The arrangement of the plurality of first vacuum holes in the first receiving groove and the arrangement of the plurality of second vacuum holes in the second receiving groove can both be arranged uniformly in a matrix, which is not specifically limited here, so as to be able to fix and adsorb the optical elements, and during the bonding process, the relative surfaces of the two optical elements to be bonded can remain parallel.

[0049] In actual operation, the vacuum generator 50 is turned on. When the optical element needs to be sucked through the vacuum hole, the air inside the top tube is sucked through the exhaust pipe to make the top tube negatively pressurized, and the air in the first receiving groove and the inner cavity of the first receiving groove is sucked through the exhaust pipe, so that the vacuum hole can suck the air. When the exhaust pipe extracts the gas, the gas is continuously discharged through the exhaust pipe, so that the vacuum hole can continuously suck the optical element, that is, the first optical element 12 can be firmly adsorbed in the first receiving groove, and the second optical element 22 can be firmly adsorbed in the second receiving groove. Generally, the depth of the first receiving groove is slightly smaller than the thickness of the first optical element 12, and the depth of the second receiving groove is slightly smaller than the thickness of the second optical element 22, so that the gluing surface of the optical element is higher than the jig, which facilitates gluing. This vacuum adsorption fixing method can not only protect the integrity of the optical element and prevent pollution, but also avoid position displacement during the gluing process, thereby improving the gluing accuracy.

[0050] Preferably, a light hole 21 is provided at the center of the bottom of the first containing groove, a collimating laser 13 is provided at the center of the bottom of the first containing groove, and the light hole 21 is coaxial with the light emitted by the collimating laser 13 .

[0052] Preferably, a placement groove is provided at the bottom of the first containing groove, and the placement groove can place the collimating laser 13 .

[0053] Preferably, the light through hole 21 is in the shape of a circular light through hole 21 or a square light through hole.

[0054] Specifically, according to Figure 3 A collimated laser 13 is provided at the bottom center of the first receiving groove. In a preferred embodiment, a storage groove is provided at the bottom center of the first receiving groove, and the collimated laser 13 is fixed in the storage groove, wherein the size of the storage groove is determined by the collimated laser 13, and it is sufficient to accommodate the collimated laser 13. The depth of the storage groove is preferably equal to the height of the collimated laser 13 to ensure that when the optical element is fixedly adsorbed in the first receiving groove, the surface to be glued of the first optical element 12 and the surface to be glued of the second optical element 22 can still be kept parallel to each other, so as to improve the gluing efficiency.

[0055] A light hole 21 is set in the area opposite to the center of the bottom of the second gluing jig and the first containing groove, and a plane reflector 31 is set in the third clamping jig 30 toward the second gluing jig. The size of the plane reflector 31 is preferably larger than the size of the light hole 21, so as to facilitate the light emitted by the collimated laser 13 to pass through the light hole 21 and enter the plane reflector 31.

[0056] When using the centering and gluing device for gluing, the collimated laser 13 emits a collimated laser beam, which passes through the first optical element 12 and the second optical element 22 in sequence, and lands on the plane reflector 31, and then reflects the laser beam through the plane emitting mirror to return to its original path. It is possible to visually check whether the round-trip laser beams overlap, and adjust the manual six-axis displacement platform 60 to achieve the centering purpose. A driver can also be set to drive the lifting mechanism and the six-axis displacement platform 60 to achieve the centering purpose. Finally, after the first optical component is glued on the surface, the entire second positioning fixture is driven downward by the lifting support rod, and finally the second optical component and the first optical component are glued to each other.

[0057] Preferably, a plurality of light holes 21 are provided at the bottom center of the second receiving groove, and the plurality of light holes 21 are arranged in a matrix or concentric circles, and a plurality of collimating lasers 13 are provided at the bottom center of the first receiving groove. Figure 4 The positions of the multiple collimating lasers 13 correspond to the positions of the multiple light holes 21 one by one, and the light holes 21 are coaxial with the light emitted by the collimating lasers 13 .

[0058] In another embodiment, a plurality of light holes 21 may be provided at the center of the bottom of the second receiving tank, and a plurality of collimating lasers 13 may be provided at the bottom of the first receiving tank, which is more helpful to improve the centering accuracy. The light holes 21 and the second vacuum holes may be arranged alternately at the bottom of the second receiving tank, or other arrangements may be used. The shape of the light holes 21 may be circular, diamond, or rectangular. Preferably, the shapes of the plurality of light holes 21 are the same. The number of light holes 21, the collimating lasers 13, and the size of the light holes 21 are not specifically limited in this embodiment, as long as they can meet the precise centering function.

[0059] Preferably, the displacement platform 60 is an electric six-axis displacement platform 60. One end of the electric six-axis displacement platform 60 is fixedly arranged in the middle part of the lifting bracket 40, and the other end is fixedly connected to the second gluing fixture. The electric six-axis displacement platform 60 is used to realize XYZ and θ x θ y θ z The specific structure of the six-dimensional adjustment is prior art and will not be described in detail herein. In this embodiment, the six-axis displacement platform 60 is controlled manually or by a driver to adjust the position of the second bonding jig to achieve centering effect.

[0060] Similarly, when there are more than two first clamping jigs 11, second clamping jigs 20, and third clamping jigs 30, it is convenient to glue multiple optical elements of the same type. For example, there are two first clamping jigs 11, second clamping jigs 20, and third clamping jigs 30, which are arranged side by side and have the same internal structure, and two rectangular transparent optical elements can be glued; or there are more than two first clamping jigs 11 and second clamping jigs 20, and the size of the third clamping jig 30 is greater than or equal to the total area of ​​more than two first clamping jigs 11 arranged side by side, the entire surface of the third clamping jig 30 can be set with a plane reflector 31, or a plurality of plane reflectors 31 can be set on the surface of the third clamping jig 30 corresponding to the position of the light hole 21. The above methods can greatly improve the gluing efficiency and reduce labor costs.
