[0037] Figure 1 A schematic diagram of a main body structure according to an embodiment of the present application is shown. As shown in the figure, the industrial camera capable of automatic zooming according to the embodiment of the present application comprises a whole bracket 100, a first lens barrel 600, imaging lenses, a lens barrel gear 500, a motor gear set 210, a motor bracket 200, and a motor 220. The first lens barrel 600 and the motor bracket 200 are arranged on the whole bracket 100. The imaging lenses are arranged in the first lens barrel 600 and can move up and down with the rotation of the first lens barrel 600. The lens barrel gear 500 is arranged on the first lens barrel 600. The motor 220 is fixedly arranged on the motor bracket 200. The motor gear set 210 is in meshing connection with the motor 220 and the lens barrel gear 500 respectively. The motor gear set 210 drives the rotation of the lens barrel gear 500, and then drives the rotation of the first lens barrel 600, so that the imaging lenses in the first lens barrel 600 move up and down to realize zooming. Figure 1 In the embodiment, the motor 220 is fixedly arranged on the bracket of the lens barrel in cooperation with a structural member. The rotation of the lens barrel is driven by the rotation of the gear of the motor 220, so that the motor zooming is realized. The problems of inaccurate zooming and limited zooming range can be solved. Specifically, the motor 220 and the motor gear set 210 are arranged on the whole bracket 100 through the motor bracket 200.

It ensures that the power of the motor 220 can be stably and reliably transmitted to the lens barrel gear 500, thereby driving the first lens barrel 600 to rotate, improving the power transmission efficiency and stability during zooming, and ensuring smooth zooming operation.

[0041] In a specific embodiment, the lens barrel gear 500 is sleeved on the outside of the first lens barrel 600 and is fixedly connected with the first lens barrel 600. The lens inside the first lens barrel 600 moves up and down with the first lens barrel 600, and the imaging magnification changes with the movement of the lens, thereby realizing imaging zooming.

[0042] In a specific embodiment, the lens barrel gear 500 is arranged along the circumferential direction of the first lens barrel 600, so that when the lens barrel gear 500 on the first lens barrel 600 rotates with the motor gear set 210, the first lens barrel 600 can rotate along the circumferential direction. The circumferentially arranged lens barrel gears 500 are arranged at equal intervals, which can more evenly receive the power transmitted by the motor gear set 210, so that the first lens barrel 600 is more balanced in the rotating process, thereby ensuring that the imaging lens moves up and down more stably and improving the stability and clarity of imaging during zooming.

[0043] In a specific embodiment, it further comprises a second lens barrel 300 and a prism 400, which are arranged on the overall support 100, and the second lens barrel 300 is connected with the first lens barrel 600 through the prism 400.

Moreover, the overall support 100 can also be provided with through holes for installing components.

[0045] In a specific embodiment, it further comprises a camera front shell, which is arranged on the end of the second lens barrel 300 away from the prism 400 and is sleeved on the second lens barrel 300. The camera shell is arranged on the end of the second lens barrel 300 for observation, which can provide certain dustproof and waterproof functions for the camera.

[0046] In a specific embodiment, the overall support 100 is made of metal or engineering plastic.

[0047] In a specific embodiment, the motor 220 is a stepper motor 220 or a servo motor 220.

[0048] In a specific embodiment, the motor support 200 is in an "L" shape structure, including a first mounting plate and a second mounting plate, both of which are plate structures, the end of the first mounting plate is connected with the end of the second mounting plate, and the plate surface of the first mounting plate is perpendicular to the plate surface of the second mounting plate, the plate surface of the first mounting plate is provided with a motor 220 mounting hole, the motor 220 is embedded in the motor 220 mounting hole, and the second mounting plate is connected with the overall support 100. The "L" shape structure of the motor support 200 is convenient to connect with the overall support 100, reasonably uses the space to install the motor 220, enhances the connection strength and stability between the motor 220 and the overall structure, and the motor 220 is outside the overall support 100, which ensures that the motor 220 will not displace or shake during the working process, and guarantees the accuracy of the zoom operation.
