Description
Technical Field
[0001] This utility model relates to the field of visual inspection technology, specifically a visual inspection device for key components of actuators. Background Technology
[0002] The actuator's structure mainly includes cables, a lower housing, an upper housing, a motor, a worm gear, a worm wheel, and a circuit board. During the assembly process on the production line, especially in the final process of fastening the upper housing, it is necessary to visually inspect most of the assembled structures for key components to avoid performing the final assembly with assembly errors, which would affect subsequent assembly tests.
[0003] The current visual inspection process is based on a fixed camera and a laser emitter. The laser emitter illuminates a reference point on a part of the actuator, and the camera takes a picture to extract the inspection image. The inspection image is sent to the industrial control computer for comparison and analysis with a standard image to detect whether the assembly position of each part is accurate, such as the meshing of the worm and worm wheel, the connection between the worm and the motor shaft, and the connection between the wire and the worm wheel.
[0004] Since each component is three-dimensional, the inspection image taken from one place cannot show the details from another angle. Therefore, in order to solve the above problem, a visual inspection device for key components of the actuator is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a visual inspection device for key components of actuators, which can solve the problems mentioned in the background art by comparing multiple reference points and taking pictures from multiple angles.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A visual inspection device for key actuator components includes a gantry support frame. Support columns are fixedly installed on the left and right sides of the gantry support frame. Cylinders are fixedly installed on the upper side of each support column. The push rod end of each cylinder is fixedly installed with the same baffle plate. The baffle plate covers the front and rear sides of the gantry support frame during use. An LED light is fixedly installed on the top inner side of the gantry support frame. A drive assembly and an adjustment assembly are fixedly installed on the top inner side of the gantry support frame. The drive assembly is centrally located, and the adjustment assemblies are distributed circumferentially around the drive assembly. A camera is installed on the lower side of the drive assembly, and a laser emitter is installed on the lower side of the adjustment assembly.
[0007] Specifically, the drive assembly includes a first motor, a second folding plate, and a second motor. The second motor is fixedly assembled with the gantry support frame. One end of the first folding plate is fixedly mounted on the output shaft of the second motor, and the first motor is fixedly mounted on the other end of the first folding plate. One end of the second folding plate is fixedly mounted on the output shaft of the first motor, and the other end of the second folding plate is fixedly assembled with a camera.
[0008] Furthermore, both the first and second folding plates are formed by bending the same rectangular plate 160° in the center.
[0009] Specifically, the adjustment assembly includes a base, a ball head, and a pressure ring. The base is fixedly assembled with the gantry support frame. The pressure ring is screwed onto the lower side of the base. The base has a spherical groove that conforms to the ball head. The pressure ring has a spherical through groove that conforms to the ball head. The ball head is located between the spherical groove and the spherical through groove. The lower side of the ball head is fixedly assembled with the laser emitter via a connecting rod.
[0010] Furthermore, the top diameter of the spherical through groove is larger than the bottom diameter.
[0011] Specifically, a pair of L-shaped guide plates are fixedly installed on both the front and rear sides of the gantry support frame, and the shielding plate is inserted and assembled with the L-shaped guide plates.
[0012] Specifically, rubber pads are fixedly installed at the lower end of each of the shielding plates.
[0013] Compared with the prior art, the beneficial effects of this utility model are: By adjusting the component settings, the orientation of the laser emitter can be flexibly adjusted and locked, thus providing multiple accurate reference points; the camera, which drives the component to switch between multiple positions, can extract detection images from multiple angles, facilitating comprehensive comparative analysis; and the liftable baffle, in conjunction with LED lights, can provide consistent ambient light, improving the convenience of image comparison; thereby achieving the effect of improving detection accuracy.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0017] Example content: Please see Figure 1 , Figure 2 This utility model provides a visual inspection device for key components of an actuator, including a gantry support frame 7, with support columns 5 fixedly installed on the left and right sides of the gantry support frame 7, and cylinders 6 fixedly installed on the upper side of each support column 5. The cylinders 6 are vertically arranged, and the same baffle plate 8 is fixedly installed on the push rod end of the cylinder 6. When in use, the baffle plate 8 covers the front and rear sides of the gantry support frame 7. The cylinder 6 can drive the baffle plate 8 to move up and down along the gantry support frame 7 to achieve light environment isolation in the detection area. An LED light 11 is fixedly installed on the top inner side of the gantry support frame 7. The top LED light 11 provides uniform illumination to ensure consistent light during image acquisition.
[0018] The inner top of the gantry support frame 7 is fixedly installed with a drive assembly 3 and an adjustment assembly 9. The drive assembly 3 is centrally located and the adjustment assembly 9 is distributed in a circle around the drive assembly 3. A camera 2 is installed on the lower side of the drive assembly 3 and a laser emitter 1 is installed on the lower side of the adjustment assembly 9. The number of laser emitters 1 is at least two. The setting angle is adjusted by the adjustment component 9, and sufficient reference points are provided as needed. The drive component 3 is used to adjust the position of the camera 2, so as to facilitate image acquisition from multiple angles.
[0019] Please see Figure 3 The structure of driver component 3: The drive assembly 3 includes a first motor 31, a second folding plate 32, a first folding plate 33, and a second motor 34. The second motor 34 is fixedly assembled with the gantry support frame 7. One end of the first folding plate 33 is fixedly mounted on the output shaft of the second motor 34, and the first motor 31 is fixedly mounted on the other end of the first folding plate 33. One end of the second folding plate 32 is fixedly mounted on the output shaft of the first motor 31, and the other end of the second folding plate 32 is fixedly assembled with the camera 2. The axis of the output shaft of the second motor 34 is the vertical axis, and the axis of the output shaft of the first motor 31 is the inclined axis. When the second motor 34 is working, it can make the first folding plate 33 and the second folding plate 32 rotate around the vertical axis. When the first motor 31 is working, it can make the second folding plate 32 rotate around the inclined axis. The resulting dual-axis linkage structure can easily adjust the position of the camera 2.
[0020] In addition, both the first folding plate 33 and the second folding plate 32 are formed by bending the same rectangular plate 160° in the center. When the first motor 31 swings the second folding plate 32 so that the camera 2 is below the second motor 34, the acquisition end of the camera 2 is vertically downward, which facilitates image acquisition of the actuator from directly above. When the first motor 31 swings the second folding plate 32 so that the camera 2 is at the end away from the second motor 34, the acquisition end of the camera 2 is tilted and points towards the center of the actuator. The bending angle of the first folding plate 33 and the second folding plate 32 can be adjusted according to the actual use to ensure the accuracy of the image acquisition range.
[0021] Please see Figure 4 Adjust the structure of component 9: The adjustment assembly 9 includes a base 91, a ball head 92, and a pressure ring 93. The base 91 is fixedly assembled with the gantry support frame 7. The pressure ring 93 is screwed onto the lower side of the base 91. The base 91 has a spherical groove that conforms to the ball head 92. The pressure ring 93 has a spherical through groove that conforms to the ball head 92. The ball head 92 is located between the spherical groove and the spherical through groove. The lower side of the ball head 92 is fixedly assembled with the laser emitter 1 through a connecting rod. By rotating the pressure ring 93 to change the pressure of the spherical through groove and the spherical recess clamping the ball head 92, a wide range of angle adjustment and locking can be achieved, which not only ensures that the laser emitter 1 can be flexibly adjusted, but also fixes the orientation by pressing.
[0022] The top diameter of the spherical through groove is larger than the bottom diameter; this shape prevents the ball head 92 from falling out of the spherical through groove, making installation and adjustment convenient.
[0023] To further improve sealing performance: A pair of L-shaped guide plates 10 are fixedly installed on both the front and rear sides of the gantry support frame 7. The L-shaped guide plates 10 are set vertically, and the baffle plate 8 is inserted and assembled with the L-shaped guide plates 10. The baffle plate 8 can improve the accuracy of the movement and the sealing performance through the guidance of the L-shaped guide plates 10.
[0024] Rubber pads 4 are fixedly installed at the lower end of the baffles 8. When the baffles 8 fall, the rubber pads 4 can abut against the conveyor belt, effectively isolating external stray light and improving sealing.
[0025] The laser emitter 1, camera 2, first motor 31, second motor 34, cylinder 6, and LED light 11 are connected to the industrial control electromechanical system of this process to work together to complete the visual inspection operation. They can also interact with humans to adjust and set specific parameters.
[0026] The working principle of this embodiment: Installation process: Fix the two support columns 5 on both sides of the production line, and let the conveyor belt pass through the gantry support frame 7 to ensure that the pallet of each assembly actuator can enter the gantry support frame 7 for inspection; The orientation of the laser emitter 1 can be adjusted by adjusting component 9 to ensure that each laser point falls on the corresponding reference position.
[0027] Testing process: Cylinder 6 lifts the baffle plate 8, the pallet enters the gantry support frame 7 in sequence and pauses for 8 to 10 seconds, cylinder 6 first lowers the baffle plate 8 along the L-shaped guide plate 10 until the rubber pad 4 comes into contact with the conveyor belt; Next, the LED light 11 and the laser emitter 1 are turned on. The LED light 11 provides uniform ambient light, while the laser emitter 1 is used to project a laser reference point onto the actuator. Afterwards, the drive component 3 rotates the camera 2 to the middle position, front, back, left, right positions, or a set specific position in sequence to take multiple pictures in order to complete the image acquisition work and facilitate comparison and analysis with standard pictures.
[0028] Screening process: qualified actuators are conveyed to the next process, while unqualified actuators are conveyed to the recycling area for further inspection and processing.
