Detailed Implementation

[0037] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0038] Example 1

[0039] like Figures 1 to 4As shown, this embodiment proposes a focusing mechanism for adjusting the height of multiple lens components 13, including a mounting base 11 and adjustment components 12. The adjustment components 12 are mounted on the mounting base 11, and the number of adjustment components 12 is the same as the number of lens components 13. Each adjustment component 12 includes:

[0040] A movable component 121 is connected to the lens component 13 via a first connector 122;

[0041] A reset member 123, the upper end of which is used to connect to the mounting base 11, and the lower end of which is used to tighten the moving part 121;

[0042] A distance adjustment member 124 is mounted on the mounting base 11 and has an output section that can move in a vertical direction for pushing the moving member 121.

[0043] The technical advantage of this solution lies in the fact that by setting multiple adjustment components 12 to adjust multiple lens components 13 separately, the field of view detection range is effectively increased. When the size of the product being inspected is large, the height of each lens component 13 can be adjusted individually, thereby enabling each lens component 13 to focus. This allows for clearer visual inspection and judgment of objects.

[0044] In addition, the focusing mechanism in this solution only adjusts the distance between the lens component 13 and the product, without involving any improvement to the lens component 13.

[0045] The working principle and internal structure of the lens component 13 are not described in detail in this article. The contents of the lens component 13 can be referred to the solutions in the prior art. At the same time, the shape of the lens component 13 in the figure cannot be used to limit the protection scope of this application. The shape and structure of the lens component 13 in this application can also adopt other forms in the prior art.

[0046] Furthermore, the distance adjustment component 124 serves as a micro-distance adjustment mechanism.

[0047] Furthermore, the moving part 121 is a push plate 1211, which is an L-shaped member. The push plate 1211 has a vertical part and a horizontal part, with the horizontal part located above the vertical part.

[0048] Furthermore, the horizontal portion is used to press against the output portion of the distance adjustment member 124, and the vertical portion is used to install the first connector 122.

[0049] Furthermore, multiple lens components 13 are arranged along a linear array.

[0050] As one embodiment of this example, the mounting base 11 has a vertical arm 111 and a horizontal arm 112 that are fixed to each other, and the horizontal arm 112 is used to mount the distance adjustment member 124.

[0051] As one embodiment of this invention, the distance adjustment member 124 includes:

[0052] A fixing sleeve 1241 is provided, the lower end of which is fixed to the upper surface of the horizontal arm 112, and the fixing sleeve 1241 has a threaded hole.

[0053] The tensioning rod 1242 is the output part of the distance adjustment component 124. The tensioning rod 1242 has a thread on its circumferential surface and is screwed into the threaded hole of the fixed sleeve 1241. The lower end of the tensioning rod 1242 passes through the clearance hole of the horizontal arm 112 and presses against the moving component 121. The top end of the tensioning rod 1242 is located above the fixed sleeve 1241.

[0054] The upper end of the adjusting cylinder shell 1243 is connected to the top end of the tightening rod 1242 by a fastener, and the adjusting cylinder shell 1243 is located outside the fixing sleeve 1241.

[0055] The fixed sleeve 1241 has its axis arranged vertically, and both the upper and lower ends of the fixed sleeve 1241 are open.

[0056] The height of the tightening rod 1242 is greater than the height of the fixed sleeve 1241, so that the upper end of the tightening rod 1242 is higher than the fixed sleeve 1241 by a certain distance, so as to facilitate the installation of the adjusting sleeve 1243.

[0057] The lower end of the adjusting cylinder shell 1243 is open, and the upper end has an end cap 12431. The end cap 12431 is connected to the top end of the tightening rod 1242 by a fastener, wherein the fastener is a locking screw 1244. The end cap 12431 has a through hole for the locking screw 1244 to pass through, and the upper end of the tightening rod 1242 has a threaded hole for installing the locking screw 1244.

[0058] Furthermore, the fixed sleeve 1241 has scale lines on its circumference for precise adjustment of the height of the tightening rod 1242.

[0059] In one embodiment of this invention, the reset member 123 is a spring 1231, the lower end of the spring 1231 is mounted on the first connecting member 122, and the upper end of the spring 1231 is mounted on the vertical arm 111 through the second connecting member 125.

[0060] In this design, rotating the adjusting cylinder shell 1243 clockwise causes the tightening rod 1242 and the adjusting cylinder shell 1243 to move downwards, and the moving part 121 to move downwards. Rotating the adjusting cylinder shell 1243 counterclockwise causes the tightening rod 1242 to move upwards. At this time, the spring 1231 drives the moving part 121 to return to its original position.

[0061] Furthermore, the first connector 122 and the second connector 125 are screws. The first connector 122 is threadedly connected to the lens assembly 13. The housing of the lens assembly 13 is provided with a threaded mounting hole 1221 for mounting the first connector 122.

[0062] Furthermore, a plurality of the first connectors 122 are provided on one of the moving parts 121, and only one of the first connectors 122 is used to mount the spring 1231.

[0063] In this design, the spring 1231 is used to tighten the moving part 121. The tension of the spring 1231 on the moving part 121 is opposite to the thrust of the clamping rod 1242 on the moving part 121.

[0064] Example 2

[0065] like Figures 1 to 9 As shown, this embodiment proposes a camera, which includes a housing 21 for mounting the aforementioned focusing mechanism;

[0066] The mounting base 11 is fixed to the camera housing 21;

[0067] The bottom of the housing 21 is provided with a mounting groove 211, and the surface of the housing 21 is provided with a clearance opening 212 that communicates with the mounting groove 211.

[0068] The lens component 13 is disposed in the mounting groove 211, and the first connector 122 passes through the clearance opening 212.

[0069] The camera in this solution uses the aforementioned focusing mechanism, which enables effective inspection of large-sized products and continuous scanning of items in different inspection scenarios, effectively achieving the detection and judgment of items.

[0070] Furthermore, the clearance opening 212 is an oblong opening, which allows the first connector 122 to move in the vertical direction.

[0071] Furthermore, an image sensor 213 is provided on the top of the housing 21.

[0072] Furthermore, a connecting bracket 214 is fixed on the housing 21 to facilitate fixing the camera to the detection equipment.

[0073] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
