The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0020] This utility model embodiment provides an adjustable light source device for visual inspection of workpieces, such as... Figure 1-4 As shown, the adjustable light source device for workpiece visual inspection includes: a base 1; an extension frame 2 fixed on the base 1; an electric telescopic rod 3 installed on the top of the extension frame 2 for adjusting the height of the light source; a fixed frame 4 installed on the output rod of the electric telescopic rod 3; an adjustment rod 6 rotatably installed on the fixed frame 4 via a rotating shaft 5; LED beads 7 and LED strips 8 respectively disposed on the fixed frame 4 and the adjustment rod 6 for providing light source illumination; and an adjustment component disposed on the fixed frame 4 for adjusting the angle of the LED strips 8.
[0021] In this embodiment, by setting the electric telescopic rod 3, the height of the light source can be flexibly adjusted to adapt to different detection scenarios. By setting the adjustment rod 6, the angle of the light source can be flexibly adjusted, solving the problem of fixed light source angle in the prior art, which is inconvenient to adjust according to detection needs. By setting LED beads 7 and LED strips 8 to provide light source illumination, the light source illumination effect is better, which can optimize image quality. By setting the adjustment component, the angle of LED strip 8 can be adjusted, further enhancing the flexibility and convenience of light source angle adjustment.
[0022] In a further preferred embodiment of the present invention, the adjustment assembly includes a support frame 17 fixed on the fixed frame 4, a second motor 18 mounted on the support frame 17 for driving the rotating shaft 5 to rotate, and an absolute encoder 19 mounted on the fixed frame 4 for monitoring the rotation angle of the rotating shaft 5.
[0023] In this embodiment, by setting the support frame 17, a stable mounting base is provided for the second motor 18 (NEMA 8), ensuring that the drive components are stable and reliable. By setting the second motor 18, the rotating shaft 5 is driven to rotate, thereby realizing the automatic adjustment of the angle of the adjustment rod 6 and the LED light strip 8 on it, improving the convenience and accuracy of the adjustment. By setting the absolute encoder 19 (ac58-ethercat), the rotation angle of the rotating shaft 5 is monitored in real time, making the angle adjustment more precise and controllable, which is conducive to achieving accurate positioning of the light source angle.
[0024] In a further preferred embodiment of the present invention, the base 1 is provided with a sliding groove 10, a slider 11 is slidably installed in the sliding groove 10, a clamping plate 9 for holding and stabilizing the gyroscope is installed on the top of the slider 11, and an anti-slip pad for increasing friction is provided on the bottom of the clamping plate 9.
[0025] In this embodiment, by setting the slide groove 10, the sliding track of the slider 11 is provided, ensuring the stability and directionality of the slider 11's movement. The slider 11 slides within the slide groove 10 to adjust its position, allowing the clamping plate 9 to move flexibly to accommodate gyroscopes of different sizes or positions. The clamping plate 9 also serves to hold and stabilize the gyroscope, preventing it from moving or shaking during detection, thus ensuring the accuracy of the detection. The anti-slip pad at the bottom of the clamping plate 9 increases friction, further improving the stability of the clamping.
[0026] In a further preferred embodiment of this utility model, a threaded rod 13 is rotatably installed inside the base 1, and an adjusting plate 12 connected to the slider 11 is threadedly sleeved on the external thread of the threaded rod 13. The adjusting plate 12 slides in contact with the inner wall of the base 1. A first motor 14 is fixed inside the base 1. Both the first motor 14 and the threaded rod 13 are equipped with bevel gears 15, and the two bevel gears 15 mesh for transmission.
[0027] In this embodiment, by setting the threaded rod 13, the effect of threaded engagement with the adjusting plate 12 to drive its movement is achieved, realizing the precise sliding of the slider 11 in the slide groove 10. By setting the adjusting plate 12, it serves to connect the slider 11 and the threaded rod 13, and at the same time, it slides in contact with the inner wall of the base 1 to ensure the stability of the movement. By setting the first motor 14 (NEMA23) and the bevel gear 15, a transmission function is achieved, converting the rotational power of the first motor 14 into the rotation of the threaded rod 13, thereby driving the adjusting plate 12 and the slider 11 to move.
[0028] In a further preferred embodiment of the present invention, the bottom of the clamping plate 9 is inlaid with a ball bearing 16 for reducing friction, and the ball bearing 16 can contact the top of the base 1.
[0029] In this embodiment, by setting the ball bearing 16, a rolling contact is achieved between the bottom of the clamping plate 9 and the top of the base 1, which effectively reduces the friction between the two. This design reduces the resistance when the clamping plate 9 moves and improves the smoothness of movement, making it easier and less strenuous to adjust the position of the gyroscope. At the same time, the rolling contact of the ball bearing 16 also reduces wear caused by friction and extends the service life of the clamping plate 9 and the base 1.
[0030] In a further preferred embodiment of the present invention, an operation port for providing a maintenance passage is provided on one side of the base 1, and a protective door for closing the operation port is hinged on the base 1. The first motor 14, the second motor 18 and the absolute encoder 19 are all covered with protective shells, and the protective shells are provided with dustproof nets.
[0031] In this embodiment, by setting up an operating port, a maintenance channel is provided for the internal components of the equipment, facilitating technicians to inspect and maintain them. The hinged protective door effectively seals the operating port, preventing external dust and debris from entering the equipment and ensuring its cleanliness and normal operation. Protective shells are fitted over the first motor 14, the second motor 18, and the absolute encoder 19, protecting these critical components from external impacts or damage. Furthermore, dustproof nets are installed on the protective shells, further enhancing the dustproof effect and extending the service life of the equipment.
[0032] In a further preferred embodiment of this utility model, the top of the base 1 is provided with a controller 20 (CNC controller) for controlling the start and stop of various electrical appliances, the rotating shaft 5 is provided with a wiring channel, and the LED light strip 8 is equipped with a wire that extends through the wiring channel to the outside of the fixing frame 4, and the wire is provided with an electric slip ring.
[0033] In this embodiment, by setting the controller 20, the effect of centralized control of the start and stop of each electrical appliance is achieved, making the operation more convenient and unified. By setting a wiring channel in the rotating shaft 5, the wires are protected and prevented from being pulled or tangled when the adjusting rod 6 rotates, ensuring the safety and stability of the wires. By installing wires on the LED light strip 8 and extending them to the outside of the fixing frame 4 through the wiring channel, the electrical connection between the LED light strip 8 and the power supply or control system is realized. At the same time, the electric slip rings set on the wires ensure that the electrical connection is not interrupted when the rotating shaft 5 rotates, ensuring the normal operation of the LED light strip 8.
[0034] In summary, compared with related technologies, this device achieves flexible adjustment of the height and angle of the light source by setting up the electric telescopic rod 3, the adjusting rod 6 and the adjusting components, which optimizes the lighting effect and improves the image quality. At the same time, the gyroscope is stably clamped by the slide groove 10, the slider 11, the clamping plate 9 and other structures, which ensures the accuracy of detection. The overall design improves the flexibility and stability of workpiece visual inspection.
