By providing at least one first type lens 20 and a first type spacer 30 within the first cylinder 10, the first type lens 20 can be assembled by the first type spacer 30. The first type spacer ring 30 is connected with the first type lens 20, and the first type spacer ring 30 is connected with the second cylinder 40, so that no connection relation exists between the first type lens 20 and the second cylinder 40, the risk of deformation of the first type lens 20 is effectively avoided, the working stability of the first type lens is greatly improved, and the split type lens can work stably.
As shown in fig. 2 and 4, the first type lens 20 has an optical effective portion 21 and an optical bearing portion 22 coaxially disposed and connected, the optical bearing portion 22 is located outside the optical effective portion 21, the optical bearing portion 22 includes a connecting section 23 and a bearing section 24 sequentially connected from inside to outside, and the bearing section 24 bears against the first type spacer 30. The bearing section 24 and the first type spacer ring 30 are supported together to ensure that the first type spacer ring 30 and the first type lens 20 can be abutted together, thereby being beneficial to dispensing between the first type spacer ring 30 and the first type lens 20 and ensuring the accuracy of the connection position between the first type spacer ring 30 and the first type lens 20. The arrangement of the connecting section 23 is used for connecting the bearing section 24 and the optical effective part 21, so that glue is prevented from overflowing to the optical effective part 21 in the dispensing process, and stable imaging of the optical effective part 21 is ensured.
As shown in fig. 2 and 4, the thickness of the bearing section 24 is smaller than the thickness of the connecting section 23 to form a bearing region 25, and at least a portion of the first type spacer ring 30 extends into the bearing region 25 to bear against the first type lens 20. The thickness of the bearing section 24 is set smaller than that of the connecting section 23, so that a bearing area 25 into which the first type spacer ring 30 extends is formed at the bearing section 24, so that the first type lens 20 can limit the first type spacer ring 30, and the assembling position of the first type spacer ring 30 is ensured, so that quick assembly between the first type spacer ring 30 and the first type lens 20 is realized.
Meanwhile, the thickness of the connecting section 23 is set to be larger than that of the bearing section 24, so that the structural strength of the connecting section 23 can be ensured, and meanwhile, the structural strength of the bearing section 24 can be ensured.
As shown in fig. 2 and 4, the surface of the first side of the bearing section 24 is flush with the surface of the first side of the connecting section 23, so that a height difference is formed between the surface of the second side of the bearing section 24 and the connecting section 23, the area where the height difference is located is the bearing area 25, and the surface of the second side of the bearing section 24 is used as the bearing surface 241. By providing the surface of the first side of the bearing section 24 flush with the surface of the first side of the connecting section 23, the first type lens 20 is facilitated to be de-molded while a height difference is formed at the surface of the second side so that at least a portion of the first type spacer ring 30 extends into the bearing area 25 and abuts against the bearing surface 241.
As shown in fig. 2 and 4, the surface of the second side of the connection section 23 includes a connection plane 231 and a connection inclined plane 232, the connection plane 231 being connected with the optically effective portion 21 and being parallel to the surface of the first side of the connection section 23, the connection inclined plane 232 connecting the connection plane 231 with the surface of the second side of the rest section 24. That is, the connection inclined plane 232 is connected with the bearing surface 241, so that the connection inclined plane 232 can play a role in limiting the first-type spacer ring 30, so as to ensure the accuracy of assembling the first-type spacer ring 30 and the first-type lens 20, and realize rapid assembly between the first-type spacer ring 30 and the first-type lens 20.
As shown in fig. 2 and 4, the first type spacer 30 includes a spacer body 31 and a support ledge 32, the spacer body 31 is annular, the spacer body 31 has an inner annular surface 311, an outer annular surface 312, and two side surfaces connecting the inner annular surface 311 and the outer annular surface 312, and a first side surface 313 has a filling surface section 314; the support flange 32 extends from the inner annular surface 311 toward the center of the spacer body 31, the support flange 32 is connected to the second side surface 315, the support flange 32 abuts against the abutment surface 241, the inner annular surface 311 abuts against the outer peripheral surface of the first type lens 20, and at least a portion of the filling surface section 314 is adjacent to the abutment surface 241 with respect to the surface of the first side of the abutment section 24 to form a filling gap for filling glue between the filling surface section 314 and the first type lens 20. The supporting flange 32 can support the first lens 20 to achieve the functions of supporting and limiting the first lens 20, and the spacer body 31 is used for connecting the second cylinder 40 to ensure stable connection between the first spacer 30 and the second cylinder 40. The inner annular surface 311 is not provided with the supporting convex edge 32 and is supported against the outer peripheral surface of the first lens 20, so that the first lens 20 is prevented from shaking along the radial direction, and the stability of the position of the first lens 20 is ensured. After the first type lens 20 and the first type spacer ring 30 are brought together, a gap, or glue filled area, is formed between the filling face section 314 and the first type lens 20. Glue is filled in the filling gap to bond and fix the first type lens 20 and the first type spacer ring 30 together so as to ensure the stability of the connection between the first type lens 20 and the first type spacer ring 30.
As shown in fig. 2 and 4, the filling face section 314 is disposed at an angle to the bearing face 241. That is, the fill-surface segment 314 is angled such that a fill gap is formed between the fill-surface segment 314 and the first type lens 20 to facilitate a tight connection between the first type lens 20 and the first type spacer ring 30.
Optionally, the angle between the filling face section 314 and the bearing face 241 is greater than 0 degrees and less than 90 degrees. The bearing surface 241 is perpendicular to the optical axis, and the angle between the filling surface segment 314 and the bearing surface 241 is in the range of 0 to 90 degrees, so that the filling surface segment 314 is inclined relative to the bearing surface 241, so that glue is dispensed at the position of the filling surface segment 314, and a part of glue can be contained, so that the connection tightness between the filling surface segment 314 and the bearing surface 241 is increased.
As shown in fig. 2 and 4, the first side 313 further includes a connection face segment 316, the connection face segment 316 being remote from the bearing face 241 relative to a surface of the first side of the bearing segment 24. The connection surface section 316 is connected with the filling surface section 314, and the connection surface section 316 is close to the outer peripheral side of the first type spacer ring 30 relative to the filling surface section 314, and after the first type spacer ring 30 is assembled with the first type lens 20, the connection surface section 316 is far away from the bearing surface 241 relative to the surface of the first side of the bearing section 24, so that the glue can be effectively prevented from overflowing to the outside of the filling surface section 314.
As shown in fig. 1, the object end surface of the second cylinder 40 sequentially includes, from inside to outside, a first surface section 41, a second surface section 42, and a third surface section 43, the first surface section 41 is parallel to the third surface section 43 and perpendicular to the optical axis of the split lens, the third surface section 43 is close to the image side of the second cylinder 40 with respect to the first surface section 41, the first type spacer 30 is connected to the first surface section 41, and the first cylinder 10 is connected to the third surface section 43. By dividing the object end surface of the second cylinder 40 into the first surface section 41, the second surface section 42 and the third surface section 43, and providing a height difference between the first surface section 41 and the third surface section 43, the first type spacer ring 30 and the first cylinder 10 can be connected with the second cylinder 40 respectively, and meanwhile, interference between the first cylinder 10, the first type spacer ring 30 and the second cylinder 40 can be effectively ensured without generating interference. In addition, the second surface section 42 can also realize radial limit on the first cylinder 10, so that collision of the first cylinder 10 on the first lens 20 and the first spacer ring 30 caused by radial movement of the first cylinder 10 is avoided, and the working stability of the first lens 20 and the first spacer ring 30 is improved.
It should be noted that, the minimum distance between the inner side surface of the first cylinder 10 and the second surface section 42 is smaller than the minimum distance between the inner side surface of the first cylinder 10 and the first type spacer ring 30, so that the first cylinder 10 is not extruded to the first type spacer ring 30 after being dislocated in the radial direction, and the working stability of the split lens is effectively ensured.
As shown in fig. 6, the split lens adopts an assembly method of the split lens, and the assembly method of the split lens includes: acquiring a first-type lens 20 and a first-type spacer 30, and assembling the first-type lens 20 and the first-type spacer 30 together; acquiring a second cylinder 40 and a second lens 50, and assembling the second lens 50 into the second cylinder 40; assembling the first type spacer 30 with the second cylinder 40; the first cylinder 10 is obtained, and the first cylinder 10 and the second cylinder 40 are assembled together. The first type lens 20 and the first type spacer ring 30 are assembled together, and then the first type spacer ring 30 and the second cylinder 40 are assembled together, so that contact between the first type lens 20 and the second cylinder 40 can be avoided, and the first type spacer ring 30 is positioned on the outer periphery side of the first type lens 20, so that the first type lens 20 and the first type spacer ring 30 are conveniently glued. After the first type spacer ring 30 and the second cylinder 40 are assembled together, the first cylinder 10 and the second cylinder 40 are assembled together to form the protection of the first type lens 20 and the first type spacer ring 30, so that the working stability of the first type lens 20 and the first type spacer ring 30 is ensured.
It should be noted that, before the first spacer ring 30 and the second cylinder 40 are assembled together, the second cylinder 40 and the second lens 50 are assembled together, so that the subsequent assembly process affects the optical performance.
Specifically, in the process of taking the first-type lens 20 and the first-type spacer ring 30 and assembling the first-type lens 20 and the first-type spacer ring 30 together includes: the bearing surface 241 of the first type lens 20 bears against the first type spacer ring 30; glue is filled into the filled face section 314 of the first type spacer ring 30 and the glue is waited for to cure to bond the first type lens 20 and the first type spacer ring 30 together. The bearing surface 241 of the first lens 20 and the first spacer 30 are firstly supported together so as to facilitate the positioning of the first lens 20 and the first spacer 30, and then the first lens 20 and the first spacer 30 are bonded and fixed together through glue, so that the assembly of the first lens 20 and the first spacer 30 is completed.
Specifically, in acquiring the second cylinder 40 and the second lens 50, the process of assembling the second lens 50 into the second cylinder 40 includes: adjusting the position of the second lens 50 in the second cylinder 40 to an accurate position; glue is filled between the second type lens 50 and the second cylinder 40 and the glue is waited for curing to adhere the second type lens 50 and the second cylinder 40 together. The position of the second lens 50 in the second cylinder 40 is adjusted to an accurate position where the second lens 50 can clearly image, and then the second lens 50 and the second cylinder 40 are assembled together by dispensing. It should be noted that, the second cylinder 40 is further equipped with a light shielding plate and a second type spacer, and a light shielding plate and a second type spacer are disposed between two adjacent second type lenses 50 to ensure that the split lens forms clear images.
Specifically, the process of assembling the first type spacer ring 30 with the second cylinder 40 includes: adjusting the positions of the first type lens 20 and the second type lens 50 in the second cylinder 40 to the correct positions; glue is filled between the first type spacer 30 and the second cylinder 40 and the glue is left to cure to adhere the first type spacer 30 to the second cylinder 40. By adjusting the relative positions of the first lens 20 and the second lens 50, an optical imaging system is formed between the first lens 20 and the second lens 50, and the split lens can clearly image and then fix the first spacer ring 30 and the second cylinder 40 together through glue.
Specifically, in the process of obtaining the first cylinder 10 and assembling the first cylinder 10 with the second cylinder 40, it includes: glue is filled into the abutting part of the first cylinder 10 and the second cylinder 40, and the glue is waited for solidification so as to adhere the first cylinder 10 and the second cylinder 40 together. Finally, the first cylinder 10 and the second cylinder 40 are connected together through glue, so that the first cylinder 10 protects the first lens 20 and the first spacer 30, collision of other structures on the first lens 20 and the first spacer 30 is avoided, and working stability of the first lens 20 and the first spacer 30 is effectively guaranteed.
Example 1
As shown in fig. 1 to 3, when the surface of the bearing surface 241 opposite to the first side of the bearing section 24 is far away from the second cylinder 40, the connection surface section 316 is connected with the second cylinder 40 by glue. The provision of the support ledge 32 in this way enables the first type of lens 20 to be supported on the object side of the first type of lens 20 while the filling surface section 314 is connected to the first type of lens 20 by glue. The connection surface section 316 is connected with the second cylinder 40 through glue, so that the situation of glue connection between the first lens 20 and the second cylinder 40 can be avoided, and the working stability of the first lens 20 is effectively ensured. Meanwhile, the connecting surface section 316 is closer to the second cylinder 40 relative to the surface of the first side of the bearing section 24, so that interference between the first lens 20 and the second cylinder 40 is avoided, and the working stability of the first lens 20 is effectively ensured.
As shown in fig. 3, the height difference d between the connection surface section 316 and the surface of the first side of the bearing section 24 is greater than 0.
The present embodiment can avoid the problem of deformation or even breakage of the first type lens 20 caused by direct contact of the first type lens 20 with the second cylinder 40 in the case where the first cylinder 10 is small. However, this smaller structural space results in smaller dispensing space for the first type lens 20 and the first type spacer 30 and smaller dispensing space for the first type spacer 30 and the second cylinder 40.
Example two
The difference from the first embodiment is that the first type spacer ring 30 is positioned against the first type lens 20.
