Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to the field of industrial camera vision inspection, specifically an arc-shaped rotating device for industrial cameras. Background Technology

[0002] In automated visual inspection of electrical components and precision parts, it is often necessary to photograph the same workpiece from different angles to comprehensively detect any defects. Current technology does not allow changing the shooting angle within the same inspection process. Changing the shooting angle typically requires stopping the machine and manually adjusting the camera position, which is then locked in place by a locking mechanism. This method is inefficient and cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide an arc-shaped rotating device for industrial cameras, which solves the technical problems of cumbersome and inefficient operation of adjusting and locking the camera shooting angle in the prior art.

[0004] This utility model provides an arc-shaped rotating device for an industrial camera, comprising a fixed arc-shaped track and a sliding seat. A worm gear rack is provided on the outer surface of the fixed arc-shaped track. A mounting bracket is fixedly provided on the sliding seat, and an industrial camera is fixedly mounted on the mounting bracket. The sliding seat has an inner cavity, and a groove adapted to the fixed arc-shaped track is provided in the inner cavity of the sliding seat. The sliding seat is connected to the fixed arc-shaped track through the groove. The sliding seat and the fixed arc-shaped track form a sliding pair along the extension direction of the fixed arc-shaped track. The inner cavity of the sliding seat contains two bearing seats, a worm gear, and a motor. Each of the two bearing seats contains a bearing. Both ends of the worm gear are connected to the two bearings respectively. The output shaft of the motor is connected to one end of the worm gear. The axial direction of the worm gear is tangent to the worm gear rack. The worm gear meshes with the worm gear rack, and the lead angle of the worm gear is smaller than the equivalent friction angle between the worm gear and the worm gear rack.

[0005] Preferably, the sliding seat is provided with rollers that cooperate with the fixed arc-shaped track.

[0006] Compared with existing technologies, the advantages of this invention are positive and significant. The output shaft of the motor drives the worm to rotate. Since the worm meshes with the worm wheel and rack, and the worm wheel and rack are fixed, the worm experiences a reaction force while rotating, which pushes the sliding seat to rotate circumferentially along a fixed arc track, thereby changing the shooting angle of the industrial camera. Because the lead angle of the worm is smaller than the equivalent friction angle between the worm and the worm wheel, the worm and worm wheel and rack have a self-locking function. That is, the worm wheel and rack can only be driven by driving the worm, and not by driving the worm wheel and rack. Therefore, after the motor stops, the industrial camera can resist vibration or external interference and stably maintain its position without the need for an additional locking device.

[0009] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included in the protection scope of the present invention. The use of directional terms such as up, down, front, back, left, right, middle, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0010] like Figures 1-2 As shown, this utility model provides an arc-shaped rotating device for an industrial camera, including a fixed arc-shaped track 1 and a sliding seat 2. A worm gear rack 3 is provided on the outer surface of the fixed arc-shaped track 1. A mounting bracket 4 is fixedly provided on the sliding seat 2, and an industrial camera 7 is fixedly mounted on the mounting bracket 4. The sliding seat 2 has an inner cavity, and a groove adapted to the fixed arc-shaped track 1 is provided in the inner cavity of the sliding seat 2. The sliding seat 2 is connected to the fixed arc-shaped track 1 through the groove. The sliding seat 2 and the fixed arc-shaped track 1 form a sliding pair along the extension direction of the fixed arc-shaped track 1. Two bearing seats, a worm gear 6, and a motor 5 are provided in the inner cavity of the sliding seat 2. Each of the two bearing seats is provided with a bearing. The two ends of the worm gear 6 are respectively connected to the two bearings. The output shaft of the motor 5 is connected to one end of the worm gear 6. The axial direction of the worm gear 6 is tangent to the worm gear rack 3. The worm gear 6 meshes with the worm gear rack 3. The lead angle of the worm gear 6 is smaller than the equivalent friction angle between the worm gear 6 and the worm gear rack 3.

[0011] Preferably, the sliding seat 2 is provided with rollers that cooperate with the fixed arc-shaped track 1.

[0012] The working principle of this utility model:

[0013] Before use, the fixed arc track 1 of the industrial camera's arc rotating device is installed on a mobile device. During use, the mobile device moves the industrial camera's arc rotating device above the electrical component 8, takes a picture at a specified angle, and checks whether the electrical component 8 has defects. If the same component or different components need to be photographed at different angles, the motor 5 is started. The output shaft of the motor 5 drives the worm 6 to rotate. Since the worm 6 meshes with the worm gear rack 3, and the worm gear rack 3 is fixed, the worm 6 will be subjected to a reaction force while rotating, thereby pushing the sliding seat 2 to rotate circumferentially along the fixed arc track 1, which in turn drives the industrial camera 7 to change the shooting angle.

[0014] Because the lead angle of the worm 6 is smaller than the equivalent friction angle between the worm 6 and the worm wheel, the worm 6 and the worm wheel rack 3 have a self-locking function. That is, the worm wheel rack 3 can only be driven by driving the worm 6, and the worm 6 cannot be driven by driving the worm wheel rack 3. Therefore, after the motor stops, the industrial camera 7 can resist vibration or external force interference and can stably maintain the position of the industrial camera 7 without additional locking devices.
