Description

Technical Field

[0001] The utility model relates to the technical field of camera lens processing, in particular to a jig for anti-fogging camera lenses. Background Art

[0002] The impact of fogging on vehicle-mounted cameras on unmanned driving systems is obvious. Fogging will lead to a decline in camera image quality and increase the risk of accidents. Therefore, when processing the camera lens, the lens needs to be anti-fog treated to give it an anti-fog effect.

[0003] When processing camera lenses, it is usually necessary to clean the concave surface of the lens, and then make a base film on the concave surface of the lens by evaporation or immersion pulling (to improve the adhesion and durability of the anti-fog film), and then drip anti-fog liquid on the concave surface of the lens, and then let the lens with anti-fog liquid stand for 10 to 30 minutes to form an anti-fog film between the anti-fog liquid and the base film of the lens, and finally clean the lens to remove excess anti-fog liquid.

[0004] However, in the actual processing process, since the concave surface of the lens has a certain curvature, it is necessary to fill the entire concave surface with anti-fog liquid. However, the amount of anti-fog liquid added is much larger than the amount required for forming the anti-fog film, which will result in a large amount of anti-fog liquid being wasted, thereby increasing production costs. Therefore, in order to solve the above-mentioned problems, a jig for anti-fog processing of camera lenses is provided. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that during the current anti-fog processing of camera lenses, a large amount of anti-fog liquid needs to be filled in the concave surface of the lens, resulting in waste of anti-fog liquid and thus increasing production costs. A jig for anti-fog processing of camera lenses is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A jig for anti-fogging camera lenses comprises a chassis and a top plate connected to the chassis via a guide member, wherein a plurality of through slots are formed on the top of the chassis, and a lens body is sleeved within the through slots, wherein a plurality of convex balls are fixedly connected to the bottom of the top plate, and when the top plate is connected to the chassis, the convex balls are inserted into the concave surface of the lens body and form an arc-shaped cavity between the convex balls and the lens body.

[0008] In order to facilitate the precise insertion of the convex ball into the concave surface of the lens body, preferably, the guide member includes a positioning rod fixedly connected to the bottom of the top plate, and a positioning hole is provided on the top of the bottom plate. When the top plate is connected to the bottom plate, the positioning rod is inserted into the positioning hole.

[0009] In order to enable the positioning rod to be quickly inserted into the positioning hole, further, the bottom end of the positioning rod is fixedly connected with a guide head, and the shape of the guide head is conical.

[0010] In order to make the connection between the chassis and the top plate more stable, preferably, both sides of the chassis are fixedly connected to the shell, and both sides of the top plate are fixedly connected to the limit plates. When the top plate is connected to the chassis, the limit plates are inserted into the shell, wherein an extrusion plate is slidably installed in the shell, and a bolt is threaded on the shell, and the extrusion plate is rotatably connected to the bolt.

[0011] In order to facilitate the application of force to rotate the bolt, further, one end of the bolt away from the extrusion plate is fixedly connected to a knob, and a plurality of anti-slip strips are fixedly connected to the surface of the knob.

[0012] In order to guide the extrusion plate, further, both sides of the inner wall of the shell are provided with sliding grooves, and both sides of the extrusion plate are fixedly connected with sliders, and the sliders are connected in the sliding grooves in a transverse sliding manner.

[0013] In order to protect the surface of the lens body, preferably, a protective pad is provided on the convex ball, and the protective pad is fixedly connected to the bottom of the top plate. When the top plate is connected to the bottom plate, the protective pad contacts the top surface of the lens body.

[0014] In order to facilitate taking and placing the top plate, preferably, pull rings are fixedly connected to both sides of the top of the top plate, and the two pull rings are symmetrically arranged.

[0015] Compared with the prior art, the present invention provides a jig for anti-fogging camera lenses, which has the following beneficial effects:

[0016] 1. This jig for anti-fogging camera lenses, by aligning the top plate and the bottom plate, can drive the convex balls to squeeze the anti-fog liquid added to the concave surface of the lens body, causing the anti-fog liquid to flow and spread and fill the arc-shaped cavity formed between the lens body and the convex balls. Compared with the amount of traditional anti-fog liquid, this jig only needs 1 / 5 to 1 / 2 of the original amount of anti-fog liquid to achieve the effect of filling the concave surface, greatly reducing the waste of anti-fog liquid and thus reducing production costs. In addition, through the arrangement of multiple convex balls and through grooves, the lens body can also be processed in batches, thereby improving processing efficiency.

[0017] 2. The jig for anti-fogging camera lenses can guide the top plate through the coordinated use of positioning rods and positioning holes, so that the top plate can be quickly covered on the top of the bottom plate, so that the convex ball can be accurately inserted into the concave surface of the lens body, thereby further improving processing efficiency.

[0018] 3. The jig for anti-fogging camera lenses can fix the combined top and bottom plates by squeezing the friction resistance between the plate and the shell, making the connection between the bottom and top plates more stable and greatly reducing the instability of the convex balls in the lens body, thereby helping to improve the film-forming effect of the anti-fog liquid.

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model solves the problem that when anti-fogging the camera lens is currently processed, a large amount of anti-fogging liquid needs to be filled in the concave surface of the lens, resulting in waste of anti-fogging liquid and increasing production costs.

[0030] Example:

[0031] Reference Figure 1-Figure 7 The embodiment of the utility model provides a jig for anti-fogging processing of camera lenses, comprising a chassis 1, and also comprising: a top plate 2 connected to the chassis 1 through a guide member, a plurality of through grooves 3 being opened on the top of the chassis 1, a lens body 4 being sleeved in the through grooves 3, wherein a plurality of convex balls 5 are fixedly connected to the bottom of the top plate 2, and when the top plate 2 is connected to the chassis 1, the convex balls 5 are inserted into the concave surface of the lens body 4 and form an arc-shaped cavity between the convex balls 5 and the lens body 4, the surface of the convex balls 5 is provided with a fluorinated polymer coating, the coating material is polytetrafluoroethylene, which has extremely low surface energy and good hydrophobicity, can reduce the contact between the convex balls 5 and the anti-fog liquid components, and effectively prevent the liquid from spreading on the surface of the convex balls 5, so as to prevent the anti-fog liquid from forming a film on the surface of the convex balls 5.

[0032] Specifically, during use, the top plate 2 can be guided by the setting of the guide member so that the top plate 2 can be quickly covered on the top of the bottom plate 1. At the same time, the top plate 2 also drives the convex ball 5 to be accurately inserted into the concave surface of the lens body 4. The convex ball 5 squeezes the anti-fog liquid added to the concave surface of the lens body 4, so that the anti-fog liquid flows and spreads and fills the arc-shaped cavity formed between the lens body 4 and the convex ball 5. Compared with the traditional amount of anti-fog liquid, this fixture only needs 1 / 5 to 1 / 2 of the original amount of anti-fog liquid to achieve the effect of filling the concave surface, which greatly reduces the waste of anti-fog liquid and thus reduces production costs.

[0033] The guide member includes a positioning rod 6 fixedly connected to the bottom of the top plate 2 . A positioning hole 7 is provided on the top of the bottom plate 1 . When the top plate 2 is connected to the bottom plate 1 , the positioning rod 6 is inserted into the positioning hole 7 .

[0034] Specifically, during use, by cooperating with the positioning rod 6 and the positioning hole 7, the top plate 2 can be quickly covered on the top of the bottom plate 1, so that the convex ball 5 can be accurately inserted into the concave surface of the lens body 4, thereby improving processing efficiency.

[0035] The bottom end of the positioning rod 6 is fixedly connected with a guide head 8, which is conical in shape.

[0036] Specifically, when in use, the guide head 8 can be used to guide the positioning rod 6 so that the positioning rod 6 can be quickly inserted into the positioning hole 7 .

[0037] Both sides of the chassis 1 are fixedly connected to the shell 9, and both sides of the top plate 2 are fixedly connected to the limit plates 10. When the top plate 2 is connected to the chassis 1, the limit plates 10 are inserted into the shell 9, wherein an extrusion plate 11 is slidably installed in the shell 9, and a rubber layer is provided on the extrusion surface of the extrusion plate 11, which can increase the friction of the extrusion plate 11. A bolt 12 is threadedly connected to the shell 9, and the extrusion plate 11 is rotatably connected to the bolt 12.

[0038] Specifically, during use, when the top plate 2 and the bottom plate 1 are merged, the limit plates 10 on both sides of the top plate 2 are inserted into the shell 9, and then the bolt 12 can be rotated. Under the action of the thread, the extrusion plate 11 moves toward the limit plate 10 and presses against the surface of the limit plate 10. Through the friction resistance between the extrusion plate 11 and the shell 9, the merged top plate 2 and the bottom plate 1 can be fixed, making the connection between the bottom plate 1 and the top plate 2 more firmly, greatly reducing the instability of the convex ball 5 in the lens body 4, thereby helping to improve the film-forming effect of the anti-fog liquid.

[0039] One end of the bolt 12 away from the extrusion plate 11 is fixedly connected to a knob 13 , and a plurality of anti-slip strips 14 are fixedly connected to the surface of the knob 13 . The number of the anti-slip strips 14 is preferably 12 and they are arranged in a ring shape on the surface of the knob 13 .

[0040] Specifically, the provision of the knob 13 and the anti-slip strip 14 can facilitate the staff to apply force to rotate the bolt 12 so as to drive the extrusion plate 11 to move.

[0041] Slide grooves 15 are provided on both sides of the inner wall of the housing 9 , and sliders 16 are fixedly connected to both sides of the extrusion plate 11 . The sliders 16 are laterally slidably connected in the slide grooves 15 .

[0042] Specifically, by providing the sliding groove 15 and the sliding block 16 , the extrusion plate 11 can be guided to prevent the extrusion plate 11 from rotating together with the bolt 12 .

[0043] A protective pad 17 is provided on the convex ball 5 and fixedly connected to the bottom of the top plate 2. When the top plate 2 is connected to the bottom plate 1, the protective pad 17 contacts the top surface of the lens body 4. The material of the protective pad 17 is silicone.

[0044] Specifically, by providing the protective pad 17 , the surface of the lens body 4 can be protected to prevent the top surface of the lens body 4 from being crushed.

[0045] Pull rings 18 are fixedly connected to both sides of the top of the top plate 2, and the two pull rings 18 are symmetrically arranged.

[0046] Specifically, the provision of the pull ring 18 makes it easy to take and place the top plate 2 .

[0047] Working principle: During the use of this jig for anti-fog processing of camera lenses, first, a batch of lens bodies 4 are sequentially sleeved on the top of the through groove 3, and then an appropriate amount of anti-fog liquid is added to the concave surface of the lens body 4, and then the positioning rod 6 at the bottom of the top plate 2 is inserted into the positioning hole 7 on the top of the chassis 1, so that the top plate 2 and the chassis 1 are merged and aligned with each other. At the same time, the top plate 2 also drives the convex ball 5 to be accurately inserted into the concave surface of the lens body 4, and the anti-fog liquid added to the concave surface of the lens body 4 is squeezed by the convex ball 5, so that the anti-fog liquid flows and spreads and fills the arc-shaped cavity formed between the lens body 4 and the convex ball 5. After the anti-fog liquid in the arc-shaped cavity is allowed to stand and form a film, the top plate 2 can be removed from the chassis 1, and then the next batch of lens bodies 4 can be replaced for processing.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
