Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to an industrial camera with adaptive lighting. Background Technology

[0002] Industrial cameras typically refer to image acquisition devices specifically designed for industrial applications. They feature high stability, high precision, high frame rate, and anti-interference capabilities, and are widely used in machine vision, automated inspection, and intelligent manufacturing.

[0003] Currently, to avoid uncontrollable ambient light during photography, industrial cameras are usually equipped with supplementary lighting. Furthermore, these supplementary lights are equipped with ambient light sensors, meaning they can adjust their brightness according to the actual ambient light conditions, giving supplementary lighting components such as supplementary lights an adaptive lighting effect.

[0004] However, when the light emitted by the supplementary light shines on highly reflective surfaces such as metal and glass, it is easily reflected, resulting in glare and interfering with the imaging of the industrial camera. Although the angle of light projection can be changed by manually adjusting the position of the supplementary light, industrial cameras are usually installed in production lines, which requires stopping production during the adjustment process, thus affecting production efficiency. Furthermore, the adjustment of the projection angle is somewhat inconvenient due to the obstruction of personnel by various mechanical equipment. Utility Model Content

[0005] The main purpose of this invention is to provide an industrial camera with adaptive supplementary lighting, which aims to solve the problem of inconvenient adjustment of the projection angle of supplementary lighting in related technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

The lighting mechanism includes a connecting plate base, a lighting lamp, and an adjustment structure for adjusting the projection angle of the lighting lamp. The camera body is fixedly mounted on the connecting plate base, and the lighting lamp is flipped and mounted on the connecting plate base.

[0008] Furthermore, the camera body includes a lens and a body, with the body and lens located on opposite sides of the connecting plate base.

[0009] Furthermore, the connecting plate base is provided with a flip base, and the supplementary light includes a lamp plate base, which is symmetrically and evenly distributed around the flip base.

[0010] Furthermore, the adjustment structure includes a first adjustment slider, an adjustment motor, a drive screw, and a first adjustment connecting rod. The two ends of the first adjustment connecting rod are rotatably connected to the first adjustment slider and the supplementary light, respectively. The first adjustment slider is drivenly connected to the drive screw and slidably connected to the connecting plate seat. The drive screw is linked with the output shaft of the adjustment motor.

[0011] Furthermore, the adjustment structure also includes a second adjustment slider and a second adjustment link, with the second adjustment link and the first adjustment link located on opposite sides of the fill light; the two ends of the second adjustment link are rotatably connected to the second adjustment slider and the fill light, and a connecting rod is provided between the first adjustment slider and the second adjustment slider to enable them to move together.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] like Figure 1 As shown, this embodiment proposes an adaptive supplementary lighting industrial camera, mainly including a camera body 1 and a supplementary lighting mechanism 2. The supplementary lighting mechanism 2 includes a connecting plate base 21, a supplementary light 22, and an adjustment structure 23 for adjusting the light projection angle of the supplementary light 22. The supplementary light 22 should be equipped with an ambient light sensor, which is electrically connected to the control panel of the supplementary light 22. When the ambient light sensor detects that the brightness of the surrounding ambient light is lower than the system-set threshold, the ambient light sensor will send an adjustment signal to the control panel of the supplementary light 22 to increase the brightness of the supplementary light 22 or turn on the supplementary light 22 to increase the brightness of the surrounding environment; conversely, it will reduce the brightness of the supplementary light 22 or even turn off the supplementary light 22 to reduce the brightness of the surrounding environment, so that the surrounding environment is in a state that is convenient for the camera body 1 to shoot, ensuring the clarity of the image captured by the camera body 1.

[0027] The connecting plate base 21 is fixedly connected to the external production equipment. The specific way it is fixedly connected to the external production equipment depends on the type of production line equipment actually used in the external environment. This embodiment will not elaborate further. The camera body 1 is fixedly mounted on the connecting plate base 21, and the fill light 22 is flipped and mounted on the connecting plate base 21. That is, in this embodiment, the connecting plate base 21 is used as the main carrier and is fixedly mounted in the external production equipment.

[0028] The existence of the adjustment structure 23 eliminates the need for workers to crawl into the production equipment and manually adjust the beam angle of the fill light 22. This improves the safety of the fill light 22 adjustment and allows for external adjustment of the fill light 22, facilitating beam angle adjustment. It also prevents the light emitted by the fill light 22 from being reflected off highly reflective surfaces such as metal and glass when dealing with 2D products like appliance panels, thus ensuring the imaging of the camera body 1. Furthermore, because the adjustment is controlled directly from outside the equipment, there is no need to stop the production line, reducing equipment restart time and ensuring production efficiency to a certain extent.

[0029] like Figures 2-4 As shown, the adjustment structure 23 in this embodiment mainly includes a first adjustment slider 231, an adjustment motor 232, a drive screw 233, and a first adjustment connecting rod 234. The two ends of the first adjustment connecting rod 234 are rotatably connected to the first adjustment slider 231 and the supplementary light 22, respectively. The first adjustment slider 231 is driven to the drive screw 233 and slidably connected to the connecting plate seat 21. The drive screw 233 is linked to the output shaft of the adjustment motor 232. The adjustment motor 232 is fixedly installed inside the connecting plate seat 21 to ensure that the adjustment motor 232 can stably provide driving force. That is, this embodiment relies on the screw-driven connection structure to control whether the supplementary light 22 rotates. The rotation of the screw is controlled by the adjustment motor 232. Thus, by controlling the forward and reverse rotation and the rotation angle of the output shaft of the adjustment motor 232, the supplementary light 22 can be controlled to rotate at a certain angle or reset.

[0030] In this embodiment, the adjusting motor 232 is preferably a stepper motor or other motor with a self-locking function. That is, when the adjusting motor 232 does not receive a control signal (such as pressing the start switch), the drive screw 233 is difficult to rotate, thereby fixing the first adjusting slider 231 and ensuring the stability of the overall structure of this embodiment.

[0031] Meanwhile, the adjustment structure 23 also includes a second adjustment slider 235 and a second adjustment link 236, with the second adjustment link 236 and the first adjustment link 234 located on both sides of the supplementary light 22, respectively. That is, there are connection points between both sides of the supplementary light 22 and the adjustment structure 23, so that the adjustment structure 23 can more stably and reliably adjust the angle of the supplementary light 22.

[0032] The two ends of the second adjusting link 236 are rotatably connected to the second adjusting slider 235 and the supplementary light 22, respectively, so that the second adjusting link 236, the second adjusting slider 235 and the supplementary light 22 can also form a linkage structure. In order to avoid the operation of this linkage structure, an additional driving element is required in this embodiment. In this embodiment, a connecting rod 237 is provided between the first adjusting slider 231 and the second adjusting slider 235 to enable them to move together. The connecting rod 237 is fixedly connected to the first adjusting slider 231 and the second adjusting slider 235. In this way, when the first adjusting slider 231 slides under the action of the driving screw 233, it can drive the second adjusting slider 235 to slide together, thereby effectively reducing the operating cost of this embodiment.

[0033] like Figure 1 As shown, the connecting plate base 21 is provided with a flip base 211, and the supplementary light 22 includes a lamp plate base 221. The lamp plate base 221 is symmetrically and evenly distributed around the flip base 211 and is rotatably connected to the flip base 211 to ensure that there are support points at both ends of the supplementary light 22 so that it can stably flip under the action of the adjustment structure 23. Moreover, since the flip base 211 is located in the center of the lamp plate base 221, it can effectively avoid interference with the adjustment structure 23 located on the side of the lamp plate base 221, and thus there is no need to make special avoidance design for the adjustment structure 23.

[0034] The camera body 1 includes a lens 11 and a body 12. The body 12 and the lens 11 are located on opposite sides of the connecting plate base 21. If necessary, the lens 11 can be equipped with a protective ring to protect it and ensure its proper function as a lens 11. Correspondingly, the body 12 and the fill light 22 are located on opposite sides of the connecting plate base 21. This not only balances the overall weight of this embodiment but also prevents the body 12 from interfering with the fill light 22 (such as blocking the light emitted by the adjusted fill light 22).

[0035] The connecting plate base 21 is provided with a first sliding groove 212 and a second sliding groove 213. The first adjusting slider 231 and the second adjusting slider 235 are slidably connected in the first sliding groove 212 and the second sliding groove 213, respectively. The drive screw 233 is rotatably connected in the first sliding groove 212. That is, through the mutual cooperation between each sliding groove and each adjusting slider, the shaking of each adjusting slider during the movement is reduced, further ensuring the stability of the adjustment structure 23. At the same time, the connecting plate base 21 is provided with a third sliding groove for the connecting rod 237 to slide and connect, ensuring that the connecting rod 237 can slide inside the connecting plate base 21 along with the first adjusting slider 231.

[0036] like Figures 4-5 As shown, in this embodiment, the projection surfaces of the first adjusting slider 231 and the second adjusting slider 235 in the axial direction of the drive screw 233 are both "U" shaped structures. This ensures that the first adjusting slider 231 and the second adjusting slider 235 can provide support points on the left and right sides of the first adjusting link 234 and the second adjusting link 236, respectively, thus ensuring the connection stability between them (so that the load is evenly distributed to both sides when under force, reducing local stress concentration). At the same time, the strong bending and torsional resistance of the "U" shaped structure is used to ensure the structural strength and stability of each adjusting slider itself.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
