[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] like Figure 1-Figure 2 As shown, the utility model provides a fixing device for a compound eye structure, including a positioning component and a pressure plate component arranged inside a sleeve 4, the positioning components are respectively arranged at both ends of the compound eye structure 3, the positioning component includes a positioning plate 1, the number of the positioning plates 1 is four, and they are respectively tightly fitted with the side surfaces of the compound eye structure 3 to enclose and form a closed frame structure around them; the pressure plate assembly includes a pressure plate 2, the number of the pressure plates 2 is four, and the two positioning plates 1 on the same side are connected by the pressure plate 2.

[0025] Through the coordinated action of the positioning assembly and the pressure plate assembly, the positioning plate 1 is enclosed to form a closed frame structure so that the lenses 31 can be neatly placed in the frame structure according to a predetermined array and accurately positioned. The two positioning plates 1 on the same side are connected by the pressure plate 2 so that the lenses 31 are stably pressed in the frame structure, eliminating the gaps between the frame structure and the lenses 31 and between the lenses 31 and the lenses 31 to avoid shaking, effectively fixing the array lenses, so that the lenses 31 can remain aligned in the horizontal and vertical directions, and because the lenses 31 are accurately positioned and pressed, the concentricity of all lenses 31 can be ensured and they are coaxial with the optical path.

[0026] As an optional implementation, it also includes an adjustment component, which is arranged in a one-to-one correspondence with the pressing plate 2 and is used to drive the pressing plate 2 to synchronously push the two positioning plates 1 to fit tightly with the side surfaces of the compound eye structure 3.

[0027] By adjusting the adjustment component, the pressure plate 2 is driven to move in the vertical direction. When the pressure plate 2 moves toward the positioning plate 1, the two positioning plates 1 are pushed to move toward the side of the compound eye structure 3 synchronously until the positioning plate 1 fits tightly with the side of the lens 31, thereby eliminating the gap between the compound eye structure 3 and the frame structure and between the lenses 31 and the lenses 31.

[0028] As an optional implementation, the adjustment assembly includes a top screw, and a through hole 41 is opened on the sleeve 4. The through hole 41 is arranged corresponding to the position of the pressing plate 2. The top screw passes through the through hole 41 and abuts against the pressing plate 2 vertically.

[0029] Furthermore, the top screw is vertically abutted against the middle position of the pressing plate 2 .

[0030] By rotating the top screw, the pressure plate 2 is driven to move in the vertical direction. The movement of the pressure plate 2 pushes the two positioning plates 1 to move toward or away from the side of the compound eye structure 3 synchronously, so that the positioning plates 1 are tightly fitted with the side of the compound eye structure 3, which can eliminate the gap between the compound eye structure 3 and the frame structure and between the lenses 31 and the lenses 31.

[0031] The four top screws are pressed in to the same distance to ensure that the lens 31 can be aligned in the horizontal and vertical directions, thereby achieving coaxial compression.

[0032] As an optional implementation, two adjacent positioning plates 1 are staggered along the length direction of the compound eye structure 3 and overlap at the corners of the corresponding compound eye structure 3 .

[0033] Such an arrangement improves the structural stability and reliability of the frame structure, especially at the corners corresponding to the compound eye structure 3 .

[0034] As an optional implementation, the two positioning plates 1 are arranged flush with each other, which is convenient for installation.

[0035] As an optional implementation, the positioning plate 1 has a straight portion 11 and an arc portion 12 , the straight portion 11 abuts against the side wall of the compound eye structure 3 , and the arc portion 12 matches the inner wall of the sleeve 4 .

[0036] The straight portion 11 abuts against the side surface of the compound eye structure 3 to provide stable support for the lens 31 .

[0037] The arc portion 12 is matched with the inner wall of the sleeve 4 to improve the connection stability with the sleeve 4 .

[0038] The combination of the arc portion 12 and the straight portion 11 enhances the overall structural strength of the positioning plate 1 .

[0039] As an optional implementation, the length of the straight portion 11 is greater than the width of the side surface of the compound eye structure 3 .

[0040] Such an arrangement enables the positioning plate 1 to fully contact the side surface of the compound eye structure 3 and is also applicable to compound eye structures 3 of different specifications.

[0041] As an optional implementation, a groove 121 for accommodating the pressing plate 2 is formed on the arc portion 12 .

[0042] Furthermore, the pressing plate 2 is a flat plate-shaped structure, and is vertically clamped with the groove 121. The positioning plate 1 is vertically abutted with the side surface of the compound eye structure 3.

[0043] The top screw drives the pressing plate 2 to move up and down smoothly along the groove 121, pushing the positioning plate 1 to fit more closely with the side surface of the compound eye structure 3.

[0044] During installation, first place the sleeve 4 vertically, screw one open end of the sleeve with a cover glass and a pressure ring to close it, then put the positioning plate 1 in to enclose the frame structure and the pressure plate 2, and then place the lens 31 in the frame structure according to the predetermined array. When the lens 31 array is placed, use the top screw to drive the pressure plate 2 to move toward the positioning plate 1, and push the two positioning plates 1 to move toward the side of the compound eye structure 3 synchronously until the positioning plate 1 fits tightly with the side of the compound eye structure 3, which can eliminate the gap between the compound eye structure 3 and the frame structure and the gap between the lenses 31. Measure the pressing distance of the top screw, and ensure that the four top screws are pressed in at the same distance to ensure that the lens 31 can be aligned in the horizontal and vertical directions, thereby achieving coaxial compression.
