[0002] A general optical system is composed of a variety of optical elements, among which optical lenses may include lenses, beam splitters, and reflectors.

[0044] Please refer to Figure 1-Figure 3 The present embodiment provides a dual optical lens adjustment module 100, including a first optical lens 110, a second optical lens 120, a first adjustment component 130 and a second adjustment component 140; the first adjustment component 130 is provided with the first optical lens 110; the second adjustment component 140 is provided with the second optical lens 120, and the second adjustment component 140 is used to adjust the position and / or distance of the second optical lens 120 relative to the first optical lens 110 so that the focus of the first optical lens 110 and the focus of the second optical lens 120 are collinear; the first adjustment component 130 is used to rotate the position of the first optical lens 110 relative to the second optical lens 120 so that the first optical lens 110 and the second optical lens 120 are orthogonal.

[0045] It can be understood that the position of the second optical lens 120 is adjusted relative to the first optical lens 110 through the second adjustment component 140 so that the focus of the first optical lens 110 and the focus of the second optical lens 120 are collinear; at the same time, since the actual focal length from the first optical lens 110 to the light source is equal to the distance between the first optical lens 110 and the light source, and the actual focal length from the second optical lens 120 to the light source is equal to the distance between the second optical lens 120 and the light source, by adjusting the distance of the second optical lens 120 relative to the first optical lens 110 through the second adjustment component 140, it is possible to fine-tune the distance between the first optical lens 110 and the second optical lens 120, thereby making the light spots after shaping of the first optical lens 110 and the second optical lens 120 uniform and symmetrical; at the same time, the position of the first optical lens 110 is rotated relative to the second optical lens 120 by setting the first adjustment component 130 so that the first optical lens 110 and the second optical lens 120 are orthogonal, thereby ensuring the verticality of the center line of the first optical lens 110 and the center line of the second optical lens 120.

[0046] In this embodiment, the first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction.

[0047] Please refer to Figure 1 In this embodiment, the dual optical lens adjustment module 100 includes a first optical lens 110 and a second optical lens 120 .

[0048] In this embodiment, the first optical lens 110 and the second optical lens 120 are both cylindrical lenses; a cylindrical lens is a non-spherical lens and can be divided into the following four types: a plano-convex cylindrical lens, a plano-concave cylindrical lens, a bi-convex cylindrical lens, and a bi-concave cylindrical lens. Among them, a cylindrical lens can effectively reduce the problems of spherical aberration and chromatic aberration, and is therefore widely used in visual inspection systems.

[0049] It is worth mentioning that the cylindrical mirror has the function of one-dimensional magnification, which is mainly used to meet the design requirements of changing the size of the image. For example, the cylindrical mirror can convert a point spot into a line spot, or change the height of the image without changing the width. Therefore, using two cylindrical mirrors can decompose the problem into two one-dimensional directions, and by combining two orthogonal cylindrical mirrors, simultaneous collimation in two directions can be achieved.

[0050] In other embodiments, the first optical lens 110 and the second optical lens 120 may both be lenses, beam splitters, or reflectors.

[0057] In this embodiment, the external force is applied along one side of the bracket 150; the application of the external force is achieved by a first sliding member and a second sliding member arranged on one side of the bracket 150, the first sliding member squeezes the first support 131 along the first rotation direction along the first direction, and the second sliding member squeezes the first support 131 along the second direction to rotate along the second rotation direction.

[0060] One end of the first fixing member 134 is fixed to the bracket 150 , and the other end is rotatably connected to the first adjusting screw 132 .

[0061] The middle section of the first adjusting screw 132 is fixedly connected to the first support 131 ; the first adjusting screw 132 passes through the two first fixing members 134 , and the first adjusting screw 132 is rotatably connected to the two first fixing members 134 on both sides of the middle section.

The first adjusting screws 133 are used to press and fix the first adjusting screw 132 and the first fixing member 134. The adjustment accuracy of the first adjusting screws 133 is 0.025 mm.

[0063] It is worth mentioning that the connection relationship of the second sliding member is consistent with the connection relationship of the first sliding member.

[0064] It can be understood that the adjustment process of the first adjustment component 130 in this embodiment is:

[0066] When the adjustment is in place, the first adjusting screw 133 and the second adjusting screw 135 and the second adjusting screw 136 of the first adjusting screw 132 on both sides are tightened, and the adjustment is completed.

[0069] Optionally, the second adjustment component 140 includes a first direction adjustment member 142 and a second direction adjustment member 143 connected to the second optical lens; the first direction adjustment member 142 is set along the first direction and moves along the first direction; the second direction adjustment member 143 is set along the second direction and moves along the second direction; the second optical lens 120 is driven to move along the first direction and / or the second direction through the movement of the first direction adjustment member 142 in the first direction and / or the movement of the second direction adjustment member 143 in the second direction.

[0070] Optionally, the second adjustment assembly 140 includes a second support 141 for adjusting the first direction and the second direction, a first direction adjustment member 142 and a second direction adjustment member 143 , and a third direction adjustment assembly for adjusting the third direction.

[0071] The second support 141 is provided with a second placement space for accommodating the second optical lens 120; the second support 141 is provided with two first hole positions along the first direction, and a first adjustment block 144 is fixed on the outer side of the second support 141, and the first adjustment block 144 is provided with two first threaded holes corresponding to the two first hole positions; the second support 141 is provided with two second hole positions along the second direction, and a second adjustment block 145 is fixed on the outer side of the second support 141, and the second adjustment block 145 is provided with two second threaded holes corresponding to the two second hole positions.

[0072] Of course, the second optical lens 120 is also provided with two first limiting holes along the first direction and two second limiting holes along the second direction.

[0073] The first direction adjusting members 142 include two, and one end of the first direction adjusting members 142 is provided with a thread matched with the first threaded hole. The two first direction adjusting members 142 are arranged along the first direction, one end of the first direction adjusting member 142 is connected to the first limiting hole of the second optical lens 120, and the other end passes through the first hole of the second support 141 and is threadedly connected to the first threaded hole of the first adjusting block 144.

[0074] The second direction adjusting member 143 includes two, and one end of the second direction adjusting member 143 is provided with a thread matched with the second threaded hole. The two second direction adjusting members 143 are arranged along the second direction, one end of the second direction adjusting member 143 is connected to the second limiting hole of the second optical lens 120, and the other end passes through the second hole position of the second support 141 and is threadedly connected to the second threaded hole of the second adjustment block 145.

[0075] Optionally, the first direction adjusting member 142 and the second direction adjusting member 143 may be adjusting members such as top screws that can be precisely adjusted, and the adjustment accuracy of the first direction adjusting member 142 and the second direction adjusting member 143 is 0.025 mm.

[0076] Optionally, one side of the third direction adjustment component is connected to the bracket 150, and the other side is connected to the second adjustment component 140, and the third direction adjustment component is used to adjust the distance between the second optical lens 120 and the first optical lens 110 along the third direction.

[0077] Please refer to Figure 1-Figure 3 The third direction adjustment assembly includes a third adjustment block 146, a fourth adjustment block 147 and an electric adjustment module 148; one side of the third adjustment block 146 is fixed to the second adjustment assembly 140; one side of the fourth adjustment block 147 is slidably connected to the other side of the third adjustment block 146, and the other side is fixed to the bracket 150. The output end of the electric adjustment module 148 is connected to the third adjustment block 146 and is used to adjust the position of the third adjustment block 146 along the third direction.

[0078] It can be understood that the adjustment process of the second adjustment component 140 in this embodiment is:

[0079] The first direction adjusting member 142 is manually rotated along the first direction, and the first direction adjusting member 142 rotates relative to the first adjusting member and pushes the second optical lens 120 along the first direction, thereby achieving adjustment of the second optical lens 120 in the first direction.

[0080] The second direction adjusting member 143 is manually rotated along the second direction, and the second direction adjusting member 143 rotates relative to the second adjusting member and pushes the second optical lens 120 along the second direction, thereby achieving adjustment of the second optical lens 120 in the second direction.

[0081] It is understandable that the position of the second optical lens 120 is adjusted along the first direction and / or the second direction by the second optical module, thereby ensuring that the midpoint of the first optical lens 110 intersects with the midpoint of the second optical lens 120 .

[0082] Through the electric adjustment of the electric adjustment module 148, the third adjustment block 146 moves along the third direction, and at the same time the third adjustment block 146 drives the entire second support 141 to move, thereby adjusting the distance between the second optical lens 120 and the first optical lens 110 along the third direction.

[0083] It can be understood that by adjusting the relative distance between the second optical lens 120 and the first optical lens 110 along the third direction, clear focus can be achieved, thereby ensuring a uniform light spot.

[0084] At the same time, when the midpoint of the first optical lens 110 and the midpoint of the second optical lens 120 intersect, the focus of the first optical lens 110 and the focus of the second optical lens 120 are adjusted to be collinear, so as to ensure the uniformity and symmetry of the light spot.

[0085] It is worth mentioning that the first adjustment component 130, the second adjustment component 140 and the bracket 150 use part of the adjustment plane as the base 160 substrate for the next degree of freedom adjustment, saving space and materials.

[0086] In summary, the dual optical lens adjustment module 100 proposed in this embodiment realizes the adjustment of the first optical lens 110 relative to the second optical lens 120 along the Rz direction by setting the first adjustment component 130, so that the first optical lens 110 and the second optical lens 120 are orthogonal, ensuring the verticality of the center line of the first optical lens 110 and the center line of the second optical lens 120; the second optical lens 120 is realized by setting the second adjustment component 140. The adjustment of the second optical lens 120 relative to the first optical lens 110 along the first direction, the second direction and the third direction is achieved, so that the first optical lens 110 and the second optical lens 120 can be clearly focused, thereby ensuring a uniform light spot; the dual optical lens adjustment module 100 can achieve four degrees of freedom adjustment according to actual usage requirements, and has a reasonable spatial layout and a compact size.
