Description

Technical Field

[0001] The invention relates to the technical field of clamps, and more specifically to a positioning and assembling device based on a fisheye lens. Background Art

[0002] The fisheye lens is a wide-angle lens with a very short front lens diameter and a parabolic shape that bulges out from the front of the lens. The fisheye lens is widely used in high-definition sports cameras, drone cameras, panoramic monitoring, and vehicle-mounted cameras due to its large field of view. Usually, when assembling a fisheye lens, it is necessary to clamp and fix the fisheye lens and the fisheye lens PCB board.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and the invention. It should be understood that the specific invention described herein is only used to explain the present invention and is not used to limit the present invention.

[0031] See also Figure 1 and Figure 2 , a positioning and assembling device based on a fisheye lens, comprising: a fixture body, a fixture elastic stopper, a lens clamping block, a slider, a toggle rod and a clamping claw toggle block;

[0032] A lens placement groove is provided on the fixture body, and the fisheye lens to be assembled is placed in the lens placement groove. A stopper installation groove is provided on the fixture body, and the fixture elastic stopper is installed in the stopper installation groove.

[0033] The lens clamp block is arranged on the clamp body, and at least two shift block installation grooves are arranged on one side of the clamp body, and the clamp claw shift block is arranged in the shift block installation groove;

[0034] One end of the toggle lever is connected with the lens clamp block, and the other end of the toggle lever abuts against one side of the clamping claw toggle block; the slider is installed on the fixture body, and the slider is clamped with the clamping claw toggle block.

[0035] Furthermore, a clamp block slide groove is provided on the clamp body, the clamp block slide groove is opened at the bottom of the stop block installation groove, and the lens clamp block is slidably arranged in the clamp block slide groove.

[0036] Furthermore, the positioning and assembling device based on the fisheye lens further includes a spring, the fixture body is provided with a spring mounting hole, the spring is arranged in the spring mounting hole, and one end of the spring is connected to the elastic stopper of the fixture.

[0037] Furthermore, the main function of the spring is to provide restoring elastic force for the clamping mechanism (i.e., the jig elastic block and the lens clamp block). When the lens clamp block and the jig elastic block are opened under the action of external force, the spring is stretched and generates restoring elastic force. When the external force acting on the lens clamp block and the jig elastic block disappears, the lens clamp block and the jig elastic block are reset under the action of the restoring elastic force of the spring, thereby realizing the opening and automatic locking functions of the clamp.

[0038] Furthermore, a through slot is provided on the fixture body. When the fisheye lens is positioned and clamped, the fisheye lens PCB board is aligned and placed in the through slot provided on the fixture body, and then the fisheye lens is aligned and installed on the fisheye lens PCB board by screws, thus realizing the point installation function of the fisheye lens.

[0039] The shape of the through groove arranged on the clamp body is adapted to the shape of the fisheye lens PCB board, which can play a role in positioning the fisheye lens PCB board, effectively preventing the problem of inaccurate positioning between the fisheye lens and the fisheye lens PCB board caused by human misoperation, thereby causing damage to the fisheye lens PCB board, and is easy to use.

[0040] Furthermore, the fisheye lens to be assembled includes a fisheye lens and a fisheye lens cover. When the fisheye lens to be assembled is positioned and assembled, first, the staff pushes the slider to rotate the clamping claw block. The rotation of the clamping claw block drives the toggle rod to move outward, so that the lens clamp and the elastic block of the jig are synchronously opened outward (i.e., the clamp is opened) under the drive of the toggle rod. Then the staff puts the fisheye lens cover and the fisheye lens into the lens placement slot in turn. When the external force applied to the slider disappears, the lens clamp and the elastic block of the jig return to their positions under the action of the restoring force of the spring and position and clamp the fisheye lens, thereby realizing the positioning and clamping function of the fisheye lens.

[0041] Furthermore, a toggle rod mounting hole is provided on the lens clamp, and one end of the toggle rod is clamped in the toggle rod mounting hole, and the movement of the toggle rod will drive the lens clamp to move synchronously.

[0042] Furthermore, the positioning and assembly device based on the fisheye lens further includes a clamping screw, a sliding groove is provided on the slider, the clamping screw passes through the sliding groove and presses the slider onto the fixture body, and the slider slides in a limited position along the direction of the sliding groove under the action of external force.

[0043] Furthermore, the positioning assembly device based on the fisheye lens further includes a clamp washer, a clamp backing ring, a clamp shaft and a bearing, a shaft through hole is opened on the clamping claw shift block, the clamp shaft is passed through the shaft through hole, and one end of the clamp shaft is connected to the clamp body;

[0044] The clamp washer, clamp backing ring and bearing are all sleeved on the clamp rotating shaft, the bearing is arranged in the rotating shaft through hole, and the clamp claw shift block rotates with the clamp rotating shaft as the axis under the action of external force.

[0045] Furthermore, the clamping claw shifting block comprises a rotating part, a first shifting part and a second shifting part, and the first shifting part, the second shifting part and the rotating part are integrally formed.

[0046] Furthermore, the slider is provided with at least two slots, one end of the second toggle portion is connected to the rotating portion, and the other end of the second toggle portion is engaged in the slot.

[0047] Furthermore, one end of the first toggle part is connected to the rotating part, and the other end of the first toggle part is against the toggle rod.

[0048] Specifically, the positioning and assembling device based on the fisheye lens involved in the present invention has the following working steps:

[0049] First, the staff applies an external force to the slider, so that the slider is pushed forward under the action of the external force. The movement of the slider causes the second moving part on the clamping claw block to be moved, and the clamping claw block rotates synchronously under the drive of the second moving part. The rotation of the clamping claw block causes the first moving part to rotate synchronously and drives the moving rod to move to both sides. At this time, the lens clamp moves synchronously to both sides under the drive of the moving rod, so that the whole device is in an open working state. At this time, the spring undergoes elastic deformation and generates a restoring elastic force.

[0050] Afterwards, after the staff placed the fisheye lens and the fisheye lens cover into the lens placement slot, they removed the external force acting on the slider. At this time, the lens clamp moved towards the middle under the action of the spring return force, and the toggle rod moved from both sides to the middle and drove the clamping claw to rotate. As the slider was pushed back and reset, the lens clamps on both sides clamped the fisheye lens, realizing the positioning and automatic clamping functions of the fisheye lens.

[0051] The present invention constructs a positioning and assembling device based on a fisheye lens, comprising a fixture body, a fixture elastic stopper, a lens clamping block, a slider, a toggle rod and a clamping claw toggle block. The clamping and unlocking of the fisheye lens are realized through the linkage between the mechanisms, which reduces manual operation, improves production efficiency, and achieves accurate positioning, avoids the problem of inaccurate positioning between the fisheye lens and the fisheye lens PCB board due to human misoperation, thereby causing damage to the fisheye lens PCB board, and is easy to use.

[0052] Although the present invention is disclosed through the above invention, the protection scope of the present invention is not limited thereto. Without departing from the concept of the present invention, deformation and replacement of the above components shall fall within the scope of the claims of the present invention.
