Description

Technical Field

[0001] The present invention relates to the technical field of automobile glass appearance detection technology, and in particular to an adjustable automobile glass appearance detection device and a detection method. Background Art

[0002] In the automotive manufacturing industry, automotive glass, as a critical component of vehicles, has a significant impact on its appearance quality, both in terms of safety and aesthetics. Appearance defects not only affect the optical properties of the glass but can also cause cracks due to stress during driving, threatening the safety of drivers and passengers. As consumers' expectations for automotive quality continue to rise, automakers are placing higher demands on the accuracy and efficiency of automotive glass appearance quality testing. Traditional manual inspection methods, which rely primarily on visual observation and simple tool measurements, are significantly affected by subjective factors and fatigue, resulting in poor consistency in test results and low efficiency, making them unable to meet the demands of modern large-scale automobile production. In order to solve the above defects, the existing technology (Announcement No. CN213239970U, Chinese patent with announcement date of 2021-05-18) is a Sai Neng optical inspection equipment for glass appearance inspection, which is provided with a servo motor, a fixed frame, a moving block, a threaded rod, a limit block and a clamping plate. The servo motor is started, and the output end of the servo motor drives the threaded rod to rotate through a coupling. The moving block is sleeved on the outside of the threaded rod, and its internal thread is engaged with the external thread of the threaded rod. The threaded rod rotates, driving the moving block to move relatively. One side of the moving block is embedded in a moving groove provided on one side of the fixed frame to improve the movement stability. When the moving block drives the clamping plate to move relatively in the reserved groove, the glass can be strongly clamped. In this way, glass of different thicknesses can be automatically clamped in four directions, thereby improving the applicability of the equipment. Prior art (Announcement No. CN208780133U, Chinese patent announcement date April 23, 2019) An automatic inspection device for automotive glass uses a point laser to acquire the coordinates of multiple points on the glass's curved surface, and a line laser to acquire the coordinates of each point on the glass's black edge. A controller compares the coordinates of designated points and / or specific points with the coordinates of designated points and / or specific points on a standard sample as needed to obtain a difference. The controller or the user can determine whether the automotive glass is qualified based on the difference. This automatic inspection device for automotive glass can save a large number of electronic inspection tools and the space occupied by electronic inspection tools. It can also achieve the purpose of inspection without moving the automotive glass under the action of a fixed fixture, thereby improving the inspection accuracy. In the above scheme, when positioning the automobile glass, the direct contact with the glass is linear extrusion, clamping and fixing. However, the automobile glass will have a certain degree of curvature after production. When clamped by the plywood, the contact area between the plywood and the glass is relatively small, and the pressure is concentrated in a local area, which can easily cause indentations on the glass surface and even cause the glass to break. Especially for some thin or high-strength automobile glass, the clamping process is not smooth and natural. When testing automobile glass of different thicknesses, complex alignment and clamping operations are also required. Moreover, the detection component is not in a relatively parallel state with the automobile glass during the detection process. Changes in the distance or angle between the detection component and the glass surface can easily lead to detection errors. For curved automobile glass, applying appropriate detection methods can more accurately capture subtle defects on the glass surface and improve the accuracy and reliability of detection. Summary of the Invention

[0003] The purpose of the present invention is to provide an adjustable automobile glass appearance inspection device and inspection method to solve the problem that the existing automobile glass appearance inspection equipment proposed in the above background technology adopts a clamp-type positioning component for the automobile glass during use. The contact area between the clamp and the glass is relatively small, and the pressure is concentrated in a local area, which easily causes indentations on the glass surface. In addition, when inspecting automobile glass of different thicknesses, complex alignment and clamping operations are also required. At the same time, changes in the distance or angle between the inspection component and the glass surface can easily lead to detection errors.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: an adjustable automobile glass appearance inspection device and inspection method, comprising a workbench, the top of which is connected to a top plate via columns on all sides, and a detector for inspecting the appearance of automobile glass is provided at the bottom of the top plate; Side panels are symmetrically fixed on the left and right sides of the top of the workbench. Notches are provided on the side panels. Moving panels are symmetrically slidably connected in the notches. Positioning arc panels are hinged on the outer sides of the moving panels for accurately positioning the automobile glass. The positioning arc panels are in contact with the top and bottom edges of the automobile glass. A curvature adjustment component is provided between the slide plate and the positioning arc plate, and the curvature adjustment component adjusts the use state of the positioning arc plate corresponding to the thickness change of the detected automobile glass; A guide plate is provided on the inner side of the bottom of the top plate, and the top of the detector is in sliding contact with the bottom of the guide plate. A trajectory adjustment component is provided on the top of the guide plate, and the trajectory adjustment component adjusts the state of the guide plate according to the thickness change of the automobile glass to keep it parallel to the automobile glass.

[0005] Furthermore, electric push rods are installed in the upper and lower inner walls of the recess of the side panel, and the outer portion of the electric push rods is fixedly connected to the upper and lower movable plates, and the movable plates drive the positioning arc plates to position and fix the automobile glass.

[0006] Furthermore, the curvature adjustment assembly includes a piston plate arranged outside the movable plate, the piston plate is sealed and slidably connected to the oil chamber, the oil chamber is opened in the upper and lower inner walls of the recess, and the oil chamber is connected to the inside of the sleeve through a connecting pipe.

[0007] Furthermore, the sleeve and the slide are arranged between the top of the movable plate and the top of the positioning arc plate, the slide is slidably connected in the sleeve, the top of the upper movable plate is installed with a sleeve, the slide is connected to the top of the positioning arc plate, the top of the lower movable plate is installed with a slide, and the sleeve is fixed to the top of the movable plate.

[0008] Furthermore, the positioning arc plates on the upper and lower sides rotate as the thickness of the automobile glass changes. The upper positioning arc plate rotates downward as the glass thickness increases, and the lower positioning arc plate rotates upward as the glass thickness increases, so that the positioning arc plate always fits the outer side of the automobile glass.

[0009] Furthermore, the trajectory adjustment assembly includes a pull rope fixed to the top of the upper movable plate inside the side panel, the top of the pull rope is connected to the end of the first screw, the first screw is rotatably connected to the slide groove symmetrically opened at the bottom of the top panel, a first screw is installed between the first screw and the inside of the top panel, the first screw is rotatably connected to the slide groove symmetrically opened at the bottom of the top panel, and a first torsion spring is installed between the first screw and the top panel.

[0010] Furthermore, the guide plate on the top plate is set as a curved structure, and connecting rods are symmetrically hinged on the top of both sides of the guide plate. A slider is hinged on the top of the connecting rod, and the slider is slidably connected in the slide groove. The slider is threadedly connected to the first screw, and the threads of the first screw on both sides are in opposite directions.

[0011] Furthermore, a motor is installed inside the right side of the top plate, and the output end of the motor is connected to the second screw on the front and rear sides through a sprocket mechanism. The second screw is rotatably connected to the transverse groove opened on the inner walls of the front and rear sides of the top plate. A truss is threadedly connected to the second screw, and a connecting frame is slidably connected to the truss. A detector is vertically slidably connected to the connecting frame, and an electromagnet is provided on the top of the detector. The side panel is set to a magnetic material.

[0012] Furthermore, the bottom of the truss is hinged with a jet plate, and half gears are symmetrically installed on the front and rear sides of the jet plate shaft, and the top of the half gear is intermittently engaged with the convex teeth, and the convex teeth are arranged in groups with equal intervals at the front and rear side edges of the bottom of the top plate. A second torsion spring is installed at the hinge of the jet plate and the truss, and the jet plate forms a swinging blowing structure through the half gear, the second torsion spring and the convex teeth. Half of the swing range of the jet plate is less than the straight-line distance from the jet plate to the detector, and the jet plate is connected to the air pump installed on the rear side of the top plate through a connecting pipe.

[0013] The inspection method of the adjustable automobile glass appearance inspection equipment is as follows: S1. Place the automotive glass to be inspected between the side panels. The electric push rod drives the positioning arc plate to move through the movable plate to clamp and secure the automotive glass. The piston plate slides synchronously in the oil chamber. The sleeve pushes the slide plate out, driving the positioning arc plate to rotate. After the positioning arc plate rotates, it fits the top and bottom of the automotive glass edge, thereby effectively contacting and clamping the automotive glass. S2. While the upper positioning arc plate is kept at the same distance from the movable plate, it rotates downward so that the upper positioning arc plate fits the upper side of the automobile glass of different thicknesses. Similarly, the lower positioning arc plate rotates upward so that it fits the lower side of the automobile glass, so that the positioning arc plate always maintains the maximum contact area, effectively reducing the risk of glass damage and protecting the integrity and appearance quality of the glass; S3. After the first screw rotates, it drives the slider to move in the slide groove. After the slider moves, it drives the two sides of the guide plate to expand or contract through the connecting rod, so that the curved surface direction of the guide plate is consistent with the direction of the automobile glass; S4. After the second screw rotates, it drives the truss to move left and right. The truss drives the detector to move with it through the connecting frame, thereby detecting the entire automobile glass. The detector moves up and down along the direction of the guide plate. The detector moves along the same direction as the curved surface of the automobile glass, and can always maintain a relatively fixed distance and angle with the glass surface, avoiding detection errors caused by changes in the distance or angle between the detection component and the glass surface.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The adjustable automobile glass appearance inspection device and inspection method are characterized in that during use, the positioning arc plate can closely fit the glass curved surface. The process of the arc plate fitting and clamping along the glass curved surface is relatively smooth and natural, and the contact with the glass is more uniform and comprehensive, thereby more accurately determining the position and posture of the glass, reducing the risk of glass damage and protecting the integrity and appearance quality of the glass. In addition, the position of the positioning arc plate can be adjusted according to the different thicknesses of the glass, and the inspection component can also be adaptively adjusted according to the specific thickness of the glass, so that the inspection component always remains parallel to the glass surface, thereby improving the accuracy of the inspection. Furthermore, when the electric push rod drives the slide plate to move, the piston plate on the slide plate will synchronously slide in the oil chamber, and the oil chamber will transport the oil to the inside of the sleeve through the connecting pipe. The sleeve will push the slide plate to slide out, and the slide plate will drive the positioning arc plate to rotate. After the positioning arc plate rotates, it fits with the top and bottom of the edge of the car glass, thereby effectively contacting and clamping the car glass, maintaining the stability of the car glass positioning, and thus improving the accuracy of the detection; Furthermore, as the thickness of the glass increases, the upper positioning arc plate rotates downward while adjusting the basic spacing with the slide plate, so that the upper positioning arc plate fits the upper side of the automobile glass of different thicknesses. Similarly, the lower positioning arc plate rotates upward to fit the lower side of the automobile glass, so that the positioning arc plate always maintains the maximum contact area, effectively reducing the risk of glass damage and protecting the integrity and appearance quality of the glass. The clamping process is relatively smooth and natural, and it is easier to control the force and position during the clamping process, making the entire positioning process simpler and faster, reducing the labor intensity of the operator and improving work efficiency. Furthermore, when the position of the upper slide changes, the pull rope drives the first screw to rotate, thereby reversing the torsion spring. The rotation of the first screw drives the slider to move in the slide slot. After the slider moves, the connecting rod drives the two sides of the guide plate to expand or contract, so that the curved surface of the guide plate is consistent with the direction of the car glass. Furthermore, after the second screw rotates, it drives the truss to move left and right along the transverse groove. When the truss moves, it drives the detector to move with it through the connecting frame, thereby detecting the entire automobile glass. When the detector moves horizontally, it will move up and down following the direction of the guide plate, so that the distance between the detector and the surface of the automobile glass is equal, and the detectors are always parallel to each other and never intersect above the glass for detection. The detector moves along the same direction as the curved surface of the automobile glass, and can always maintain a relatively fixed distance and angle with the glass surface, avoiding detection errors caused by changes in the distance or angle between the detection component and the glass surface.

Example

[0019] Based on the first embodiment, the piston plate 9, the oil chamber 10, the sleeve 11 and the slide plate 12 are also disclosed. Figure 1 - Figure 5 As shown, its specific structure is as follows: an electric push rod 6 is installed in the upper and lower inner walls of the recess 5 of the side panel 4, and the outer portion of the electric push rod 6 is fixedly connected to the upper and lower movable plates 7. The movable plate 7 drives the positioning arc plate 8 to position and fix the automobile glass. The curvature adjustment component includes a piston plate 9 arranged on the outside of the movable plate 7. The piston plate 9 penetrates the seal and slides in the oil chamber 10. The oil chamber 10 is opened in the upper and lower inner walls of the recess 5. The oil chamber 10 is connected to the inside of the sleeve 11 through a connecting pipe. The sleeve 11 and the slide plate 12 are arranged on the movable plate 7.

The upper positioning arc plate 8 rotates downward as the thickness of the glass increases, and the lower positioning arc plate 8 rotates upward as the thickness of the glass increases, so that the positioning arc plate 8 always fits the outer side of the automobile glass. During use, when the electric push rod 6 drives the movable plate 7 to move, the piston plate 9 on the movable plate 7 will slide synchronously in the oil chamber 10, and the oil chamber 10 will transport the oil to the inside of the sleeve 11 through the connecting pipe.

The thicker the glass, the upper positioning arc plate 8 rotates downward while maintaining the basic spacing adjustment with the movable plate 7, so that the upper positioning arc plate 8 fits the upper side of automobile glass of different thicknesses. Similarly, the lower positioning arc plate 8 rotates upward and fits the lower side of the automobile glass, so that the positioning arc plate 8 always maintains the maximum contact area, effectively reducing the risk of glass damage and protecting the integrity and appearance quality of the glass. The clamping process is relatively smooth and natural, and it is easier to control the force and position during the clamping process, making the entire positioning process simpler and faster, reducing the labor intensity of the operator and improving work efficiency.

The slider 16 is threadedly connected to the first screw 18. The threads of the first screws 18 on both sides are opposite. A motor 20 is installed inside the right side of the top plate 3. The output end of the motor 20 is connected to the second screws 21 on the front and rear sides through a sprocket mechanism.

An electromagnet is provided on the top of the detector 25, and the side plate 4 is set to a magnetic material. During use, as the position of the upper movable plate 7 changes, the pull rope 13 drives the first screw 18 to rotate, thereby reversing the first torsion spring 19. The rotation of the first screw 18 drives the slider 16 to move in the slide groove 17. After the slider 16 moves, it drives the two sides of the guide plate 14 to expand or contract via the connecting rod 15, so that the curved surface of the guide plate 14 is consistent with the direction of the automobile glass. After the motor 20 is started, it drives the second screw 21 to rotate. The rotation of the second screw 21 drives the truss 23 to move left and right along the transverse groove 22.

10. The adjustable automobile glass appearance inspection device according to claim 9, characterized in that: Also disclosed is a detection method for an adjustable automobile glass appearance detection device, the specific method steps are as follows: S1. The automobile glass to be inspected is placed between the side plates (4). The electric push rod (6) drives the positioning arc plate (8) to move through the moving plate (7) to clamp and fix the automobile glass. The piston plate (9) slides synchronously in the oil chamber (10). The sleeve (11) pushes the slide plate (12) to slide out, driving the positioning arc plate (8) to rotate. After the positioning arc plate (8) rotates, it fits the top and bottom of the edge of the automobile glass, thereby effectively contacting and clamping the automobile glass. S2. When the upper positioning arc plate (8) and the movable plate (7) are kept at a basic spacing, the upper positioning arc plate (8) is rotated downward so that the upper positioning arc plate (8) fits the upper side of automobile glass of different thicknesses. Similarly, the lower positioning arc plate (8) is rotated upward so as to fit the lower side of the automobile glass, so that the positioning arc plate (8) always maintains the maximum contact area, effectively reducing the risk of damage to the glass and protecting the integrity and appearance quality of the glass. S3, after the first screw (18) rotates, it drives the slider (16) to move in the slide groove (17), and after the slider (16) moves, it drives the two sides of the guide plate (14) to expand or contract through the connecting rod (15), so that the direction of the curved surface of the guide plate (14) is consistent with the direction of the automobile glass; S4, after the second screw (21) rotates, it drives the truss 23 to move left and right, and the truss (23) drives the detector (25) to move along with it through the connecting frame (24), thereby detecting the entire automobile glass. The detector (25) moves up and down along the direction of the guide plate (14). The detector (25) moves along the same direction as the curved surface of the automobile glass, and can always maintain a relatively fixed distance and angle with the glass surface, thereby avoiding detection errors caused by changes in the distance or angle between the detection component and the glass surface.
