Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to a camera with a rotation adjustment structure. Background Technology

[0002] In modern industrial inspection, security monitoring, and scientific research observation, camera equipment needs to have flexible spatial positioning capabilities to adapt to complex and ever-changing application scenarios. Traditional fixed cameras, due to their limited field of view, cannot meet the needs of capturing objects from multiple angles and in all directions, especially in applications such as precision workpiece inspection and 3D modeling, where it is often necessary to acquire images of the same target from multiple directions.

[0003] According to CN106990647B, an industrial camera pose adjustment device is disclosed. This technology discloses a technical solution including "a support plate, a gear shaft, a driving bevel gear, and a four-axis adjustment mechanism. The gear shaft is mounted on the support plate, and the driving bevel gear is mounted on the gear shaft. The four-axis adjustment mechanism includes a driven bevel gear, a ball screw mechanism, and a three-axis rotation adjustment mechanism. The three-axis rotation adjustment mechanism includes a rotating shaft bracket, a first rotation joint, a second rotation joint, and a third rotation joint." This device has the technical effect that "through the bevel gear transmission mechanism, the ball screw mechanism, and the three-axis rotation adjustment mechanism, the industrial camera can achieve four degrees of freedom adjustment, which is convenient and flexible. The industrial camera has a large adjustment range, and the three-axis rotation adjustment device can perform three-degree-of-freedom rotational adjustment of the industrial camera's pose, meeting the needs of optimal pose adjustment for industrial cameras in multi-view vision."

[0004] In the use of existing camera equipment, when it is necessary to adjust the shooting distance, it is often necessary to operate the actuators in multiple directions independently. This process is not only cumbersome, but also generates cumulative errors in multiple asynchronous adjustments. These errors originate from the mechanical gaps and response delays between the various adjustment units, which ultimately lead to the optical center shift, causing a deviation between the actual imaging position of the photographed workpiece and the expected target, thus affecting the accuracy of the detection results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a camera with a rotation adjustment structure. The main body component enables synchronous adjustment of the shooting distance in four directions, and the execution component enables adjustment of the pitch angle, thus achieving stable multi-directional shooting of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a camera with a rotation adjustment structure, comprising a frame, wherein a camera mechanism is mounted on the frame for multi-angle shooting, and the camera mechanism includes:

[0007] The main components include a platform fixed inside the frame, four circumferentially arranged sliding plates slidably mounted on the lower end of the platform, a base fixed on the upper end of the sliding plates, a cross bracket rotatably mounted in the middle of the bottom of the platform, connecting rods pivotally connected to the four ends of the cross bracket, and the other end of the connecting rods pivotally connected to the bottom of the sliding plates. A first cylinder is mounted on one end of the frame and is used to drive one of the sliding plates to move.

[0008] The execution component includes an adjustment part mounted on the main component for adjusting the pitch angle, and a photographing part mounted on the adjustment part for performing the shooting operation.

[0009] Preferably, the adjusting component includes a plate base disposed on the main body assembly, with arc-shaped grooves opened inside both ends of the plate base, a vertical frame fixed to the upper end of the plate base, a second cylinder pivotally connected to the upper end of the vertical frame, an arc-shaped frame pivotally connected to the lower output end of the second cylinder, and two cams rotatably mounted on the outer walls of both ends of the arc-shaped frame, with the cams located inside the arc-shaped grooves.

[0010] Preferably, the imaging component includes an adjusting rod fixed on an arc-shaped frame, two sliding sleeves are slidably mounted on the adjusting rod, a fill light and an industrial camera are respectively mounted on the upper end of the two sliding sleeves, and a knob bolt is threaded onto the sliding sleeve.

[0011] Preferably, the execution component further includes a Z-axis linear module mounted on the top of the base, and the plate base is fixed on the slider of the Z-axis linear module.

[0012] Preferably, the main component further includes four guide rails fixed to the bottom of the platform and arranged in a circular pattern, with sliders slidably mounted on the guide rails and the slide plate fixed to the bottom of the sliders.

[0013] Preferably, the arc-shaped groove has a semi-circular structure, and its cross-section is a groove that matches the outer contour of the cam.

[0014] Beneficial effects

[0015] This invention provides a camera with a rotation adjustment structure. Compared with the prior art, it has the following advantages:

[0016] 1. By placing the workpiece in the middle of the top of the platform, when the first cylinder drives one of the slides to move linearly, the force is transmitted to the cross bracket rotatably mounted on the bottom of the platform through the connecting rod pivotally connected to it. The rotation of the cross bracket will synchronously drive the other three connecting rods to move, thereby forcing all slides to produce a linked radial displacement; thus, the slides drive the actuator on the base to move closer to or further away from the workpiece synchronously, thereby achieving precise control of the shooting distance.

[0017] 2. When the second cylinder moves in extension and retraction, its piston rod pushes and pulls the middle part of the arc-shaped frame that is pivotally connected to it. Since the two ends of the arc-shaped frame are embedded and constrained in the arc-shaped groove of the plate seat through the cam, the cam then rolls in the arc-shaped groove, thereby forcing the entire arc-shaped frame to swing along the trajectory of the arc-shaped groove with the instantaneous contact point of the cam as the fulcrum, and finally achieves precise adjustment of the pitch angle of the imaging component installed on it.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a camera with a rotation adjustment structure, including a frame 1, a camera mechanism 2 mounted on the frame 1 for multi-angle shooting, and the camera mechanism 2 including:

[0026] The main component 21 includes a platform 211 fixed inside the frame 1. Four circumferentially arranged slide plates 214 are slidably installed on the lower end of the platform 211. A base 215 is fixed on the upper end of the slide plates 214. A cross bracket 216 is rotatably installed in the middle of the bottom of the platform 211. Each of the four ends of the cross bracket 216 is pivotally connected to a connecting rod 217, and the other end of the connecting rod 217 is pivotally connected to the bottom of the slide plate 214. A first cylinder 218 is installed at one end of the frame 1 and is used to drive one of the slide plates 214 to move.

[0027] The execution component 22 includes an adjustment component 222 disposed on the main component 21 for adjusting the pitch angle, and a photographing component 223 disposed on the adjustment component 222 for performing the shooting operation.

[0028] In this embodiment, by placing the workpiece at the top center of the platform 211, when the first cylinder 218 drives one of the slide plates 214 to move linearly, the force is transmitted to the cross bracket 216 rotatably mounted on the bottom of the platform 211 through the connecting rod 217 pivotally connected to it. The rotation of the cross bracket 216 will synchronously drive the other three connecting rods 217 to move, thereby forcing all slide plates 214 to produce a linked radial displacement; then the slide plates 214 drive the actuator 22 on the base 215 to synchronously move closer to or away from the workpiece, thereby achieving precise control of the shooting distance.

[0029] Specifically, the adjustment component 222 includes a plate base 2221 mounted on the main body component 21. Both ends of the plate base 2221 have arc-shaped grooves 2222 inside. A stand 2223 is fixed to the upper end of the plate base 2221. A second cylinder 2224 is pivotally connected to the upper end of the stand 2223. An arc-shaped frame 2225 is pivotally connected to the lower output end of the second cylinder 2224. Two cams 2226 are rotatably mounted on the outer walls of both ends of the arc-shaped frame 2225, and the cams 2226 are located inside the arc-shaped grooves 2222.

[0030] In this embodiment, when the second cylinder 2224 performs telescopic movement, its piston rod pushes and pulls the middle part of the arc-shaped frame 2225 pivotally connected to it. Since the two ends of the arc-shaped frame 2225 are embedded and constrained in the arc-shaped groove 2222 of the plate seat 2221 through the cam 2226, the cam 2226 then rolls in the arc-shaped groove 2222, thereby forcing the entire arc-shaped frame 2225 to swing along the trajectory of the arc-shaped groove 2222 with the instantaneous contact point of the cam 2226 as the fulcrum, and finally realizes the precise adjustment of the pitch angle of the imaging component 223 installed on it.

[0031] Specifically, the imaging component 223 includes an adjusting rod 2231 fixed on an arc-shaped frame 2225. Two sliding sleeves 2232 are slidably mounted on the adjusting rod 2231. A fill light 2233 and an industrial camera 2234 are respectively mounted on the upper ends of the two sliding sleeves 2232. A knob bolt 2235 is threaded onto the sliding sleeves 2232.

[0032] In this embodiment, two sliding sleeves 2232 are slidably mounted on the adjusting rod 2231 through through holes, allowing the fill light 2233 and industrial camera 2234 mounted on top of the adjusting rod 2231 to move independently and continuously along the axial direction of the adjusting rod 2231. After adjusting to the target position, the sliding sleeves 2232 are tightened by turning the knob bolts 2235 on the side to press their ends against the surface of the adjusting rod 2231, and the sliding sleeves 2232 are securely locked by friction.

[0033] Specifically, the execution component 22 also includes a Z-axis linear module 221 mounted on top of the base 215, and the plate base 2221 is fixed on the slider of the Z-axis linear module 221.

[0034] In this embodiment, the Z-axis linear module 221 drives the imaging component 223 on the execution component 222 to move up and down, which can flexibly meet the complex shooting needs of different heights, angles and distances.

[0035] Specifically, the main component 21 also includes four guide rails 212 arranged circumferentially on the bottom of the platform 211, with sliders 213 slidably mounted on the guide rails 212, and a slide plate 214 fixed to the bottom of the sliders 213.

[0036] In this embodiment, the guide rail 212 and the slider 213 cooperate to restrict the slide plate 214 on a preset radial path and eliminate lateral swaying and twisting during the movement.

[0037] Specifically, the arc-shaped groove 2222 has a semi-circular structure, and its cross-section is a groove that matches the outer contour of the cam 2226.

[0038] In this embodiment, the semi-circular structure of the arc groove 2222 limits the rolling trajectory and pitch adjustment limit angle of the cam 2226.

[0039] The working principle and usage process of this utility model are as follows: First, the workpiece to be photographed is placed in the center area of ​​the top of the platform 211. After the equipment is started, the first cylinder 218 drives one of the slide plates 214 to produce radial displacement according to the command. The slide plate transmits the thrust to the cross bracket 216 through the connecting rod 217 pivotally connected to it. The cross bracket 216 then rotates and synchronously pulls the other three connecting rods 217 to move, forcing all the slide plates 214 to produce synchronous radial sliding under the guidance of the guide rail 212 and the slider 213. This drives the base 215 and the entire execution assembly 22 above to smoothly approach or move away from the workpiece, so as to achieve precise coarse adjustment of the shooting distance.

[0040] Then, the Z-axis linear module 221 is activated, driving the plate base 2221 fixed on its sliding component and the entire adjustment component 222 and imaging component 223 to vertically lift and lower, adjusting the industrial camera 2234 to the optimal observation height of the workpiece.

[0041] Finally, the second cylinder 2224 starts working, and its piston rod pushes and pulls the middle of the arc frame 2225, forcing the cams 2226 at both ends of the arc frame to roll in the semi-circular arc groove 2222, driving the arc frame 2225 to swing along a precise arc trajectory, ultimately achieving fine adjustment of the pitch angle of the camera component 223.
