Description

Technical Field

[0001] The present invention relates to the technical field of detection instruments, and particularly relates to an automobile windshield detection device and a detection method. Background Art

[0002] Automobile windshields are essential accessories of automobile bodies, mainly playing a protective role. With the continuous development of society, automobiles have become essential means of transportation for every household, and the number of automobiles in use is increasing day by day. Traffic accidents have become an issue that cannot be ignored. Therefore, it is necessary to inspect the curvature and defects of automobile windshields to ensure the safety of the automobiles themselves. Windshield defects include scratches, cracks, bubbles, nodules, protrusions, oil stains, etc. Cracks in the windshield may start small and may not be detectable by the naked eye for a long time. Even if they are clearly detectable, the cracks may originate at positions on the windshield that the driver or passenger do not check frequently enough to be aware of their existence; if not repaired immediately, the cracks may become larger, which further reduces the appearance and safety of the windshield. Moreover, larger cracks are usually more expensive to repair. Some cracks may become large enough to make it necessary to replace the entire windshield. It is imperative to identify and repair cracks as early as possible.

[0003] The patent with the patent publication number CN109458968B discloses an arc surface detection instrument for automatically installing automobile windshields, including a bottom plate, a glue injection device, a clamping device, and a detection device. The glue injection devices are uniformly installed on the outer side of the upper end of the bottom plate, the clamping device is installed in the middle of the upper end of the bottom plate, and the detection device is installed in the middle of the upper end of the clamping device. The above detection instrument can solve the problems of high labor intensity, low work efficiency, and low accuracy in manually installing automobile windshields. At the same time, it can also detect the arc surface of the windshield and realize the functions of automatic installation and detection.

[0004] However, when the above detection instrument detects an automobile windshield, it cannot detect cracks on the automobile windshield, and when detecting cracks on the automobile windshield, it is difficult to mark the cracks on its surface. As a result, the position of the cracks after detection is inaccurate, and it is easy to have repair omissions. If the omitted cracks are not processed in time, with the extension of the use time, the cracks may become more obvious, thus affecting the transparency and safety performance of the windshield.

[0023] S3. Further start the linear moving member, and make the linear moving member drive the telescopic rod, the support block and the marking mechanism to move; the support block drives the vertical plate to move, the vertical plate drives the connecting rod, the detection member, and the electric push rod to move, and the detection roller rotates under the action of friction;

[0024] S4. The detection member detects the cracks in the windshield during the movement, and the detection roller detects the curved surface of the windshield during the rotation. When a crack is detected, the linear moving member stops moving, and the marking mechanism is driven by the electric push rod to mark the position of the crack;

[0025] S5. After the marking mechanism finishes marking, the electric push rod resets, start the linear moving member and perform the next detection until the detection is completed.

[0026] The present invention has the following beneficial effects:

[0027] 1. For the automotive windshield detection device of the present invention, the position of the detection member is adjusted by the telescopic rod, and the detection roller is brought into contact with the surface of the windshield to be detected. The linear moving member finally drives the detection member to move. During the movement, the detection roller rotates. Under the action of the first spring and the detection roller, the distance between the detection member and the surface of the windshield is always kept consistent. The detection roller can detect the curvature of the windshield, and the detection member is used to detect cracks. When the detection member detects a crack, the marking mechanism is driven by the electric push rod to mark the position of the crack, so as to facilitate the staff to carry out repairs and other treatments.

[0028] 2. For the marking mechanism of the present invention, through the cooperation of the connecting block, the marking liquid spraying tank, the hose, the nozzle block, the L-shaped pressing member, and the electric push rod, when the electric push rod contracts, it drives the connecting block to move downward through the connecting rod. The connecting block moves downward and presses the pressing end of the L-shaped pressing member, so that the pressing end of the L-shaped pressing member transports the marking liquid in the marking liquid spraying tank to the nozzle block through the hose and sprays it onto the crack of the automotive windshield, thereby marking the crack on the surface of the automotive windshield, so as to facilitate the subsequent staff to observe and repair the crack on the surface of the automotive windshield. At the same time, through the cooperation of the first runner, the blocking rod, the rotating rod, the second runner, the belt, and the fan plate, the detection roller rotates during the movement, which can drive the first runner to rotate, and drive the second runner to rotate through the belt. The second runner drives the fan plate on the rotating rod to rotate, thereby fanning the surrounding air flow and accelerating the drying speed of the marking liquid, avoiding the situation that the mark at the crack on the surface of the automotive windshield is accidentally wiped off.

[0029] 3. For the wiping mechanism of the present invention, through the cooperation of the moving long block, the elastic arc plate, the limiting block, the L-shaped short block, and the wiping plate, the surface of the detection roller can be wiped, avoiding the situation that the inaccurate marking of the automotive windshield is caused by the existence of the marking liquid on the surface of the detection roller. Through the cooperation of the L-shaped fixing rod, the short rod, and the round block, the wiping plate can also move left and right reciprocally to wipe the surface of the detection roller, making the wiping cleaner, and avoiding the interference of the marking liquid adhered to the detection roller during rotation to other marked positions.

[0030] 4. The cleaning mechanism of the present invention cleans the surface of the windshield through the limit block, the long rod and the brush, so as to remove the sundries on the surface of the windshield, avoiding the sundries from affecting the accuracy of the detection by the detection piece; through the cooperation of the cross plate, the fixed disc, the limit disc, the second spring, the hemispherical block and the pushing block, when the detection roller rotates, it will drive the fixed disc to rotate. When the hemispherical block contacts the pushing block, it will cause the pushing block to move, and finally drive the long rod to move. Under the action of the second spring, the long rod realizes reciprocating motion. The reciprocating motion of the long rod drives the brush to perform reciprocating motion, and the reciprocating motion of the brush can remove the sundries on the surface of the automobile windshield, improving the cleaning effect.

Detailed implementation manners

[0041] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0042] As Figures 1 to 3 shown, in an embodiment of the present invention, a vehicle windshield detection device is provided, including a base 1, a support plate 2 disposed on the top of the base 1, the support plate 2 is rotatably disposed on the top of the base 1, four hinge seats are provided on the top of the base 1, hinge rods corresponding to two of the hinge seats are provided at the bottom of the support plate 2, and rotation is achieved through a pin shaft. At the same time, an electric telescopic rod rotatably connected to the other two hinge seats is provided on the top of the base 1, and the telescopic end of the electric telescopic rod is rotatably connected to the bottom of the support plate 2; two groups of fixed arc frames 3 disposed on the top of the support plate 2, the fixed arc frames 3 are connected to the top of the support plate 2; a linear moving member 4 disposed on the top of the support plate 2 and between the two groups of fixed arc frames 3, an installation groove for installing the linear moving member 4 is opened on the top of the support plate 2, and the linear moving member 4 adopts an existing electric slide table, which will not be elaborated here; two groups of telescopic rods 5 disposed on the top of the moving end of the linear moving member 4, the telescopic rods 5 adopt electric telescopic rods; support blocks 6 disposed on the top of the telescopic ends of the two groups of telescopic rods 5, and a first spring disposed between the telescopic rods 5 and the support blocks 6, the first spring is sleeved on the outer wall of the telescopic rod 5.

[0043] Specifically, vertical plates 61 are respectively arranged on both sides of the top of the support block 6. A connecting rod 62 is vertically slidably fitted between the two vertical plates 61. Vertical sliding grooves matching the connecting rod 62 are respectively formed on the two vertical plates 61. A detection member 63 is arranged on the outer wall of the middle part of the connecting rod 62. The detection member 63 is used for detecting cracks in the windshield. The detection member 63 adopts an existing light source transceiver component, which will not be elaborated here. An electric push rod 64 rotatably fitted with the connecting rod 62 is arranged at the bottom of the inner wall of the vertical plate 61. Installation grooves 611 for installing the electric push rod 64 are formed on the opposite side walls of the two vertical plates 61. An annular limiting groove is formed on the outer wall of the connecting rod 62. An arc-shaped limiting block slidably fitted with the annular limiting groove is arranged at the output end of the electric push rod 64. The cross-section of the annular limiting groove is in a T-shaped structure, so as to realize the rotational cooperation between the connecting rod 62 and the electric push rod 64. The cooperation between the arc-shaped limiting block and the annular limiting groove enables the connecting rod 62 to be smoothly driven to rise and fall by the telescopic movement of the electric push rod 64. Detection rollers 65 are respectively rotatably arranged on the outer wall of the connecting rod 62 and on both sides of the detection member 63. The detection rollers 65 are of the prior art and will not be described in detail here. The detection rollers 65 are electrically connected to an external detection instrument and are used for detecting the curved surface of the windshield. A marking mechanism 7 corresponding to the detection member 63 is arranged between the two vertical plates 61. The marking mechanism 7 is connected to both ends of the connecting rod 62 in a matching manner. In this embodiment, the linear moving member 4, the telescopic rod 5, the detection member 63, and the detection rollers 65 can all be electrically connected to an external controller, and the intelligent control of the above components is realized through the controller.

[0044] Such as Figures 4 to 6As shown in the figure, the marking mechanism 7 includes connection blocks 71 respectively arranged at both ends of the connecting rod 62, a marking liquid spraying tank 72 arranged between the side walls of the two vertical plates 61. The interior of the marking liquid spraying tank 72 is hollow and used to contain the marking liquid. The top of the marking liquid spraying tank 72 is provided with a filling port, and a sealing plug is arranged on the filling port to facilitate the replenishment of the marking liquid in the marking liquid spraying tank 72 when necessary; a hose 73 arranged at the top of the marking liquid spraying tank 72 and communicating with it, a nozzle block 74 arranged at the top of the hose 73 and corresponding to the detection piece 63. The top of the nozzle block 74 has a spraying port, and the hose 73 communicates with the spraying port; L-shaped connecting rods 75 respectively arranged at both ends of the nozzle block 74, and the end of the L-shaped connecting rod 75 far from the nozzle block 74 is connected to the side of the corresponding vertical plate 61; and L-shaped pressing members 76 arranged at both ends of the marking liquid spraying tank 72 and communicating with it, and the pressing end of the L-shaped pressing member 76 is connected to the bottom wall of the connection block 71. The L-shaped pressing member 76 includes an L-shaped pipe communicating with the marking liquid spraying tank 72. The L-shaped pipe includes a horizontal pipe communicating with the marking liquid spraying tank 72 and a vertical pipe vertically connected to the end of the horizontal pipe. A pressing rod is slidably arranged in the vertical pipe, a piston is arranged on the pressing rod located in the vertical pipe, and the end of the pressing rod far from the piston is connected to the bottom of the connection block 71. When it is necessary to mark the detected crack, the linear moving member 4 is paused, the telescopic end of the electric push rod 64 contracts and drives the connecting rod 62 to slide downward along the vertical plate 61. At this time, the connection block 71 moves downward and presses the pressing end of the L-shaped pressing member 76, so that the marking liquid in the marking liquid spraying tank 72 enters the nozzle block 74 through the hose 73 and sprays out from the spraying port on the nozzle block 74, thereby marking the position of the crack detected on the windshield.

[0045] Among them, the marking mechanism 7 further includes a first runner 77 arranged on the roller shaft 651 of the detection roller 65. The first runner 77 is fixed on the roller shaft 651 by screws. When the detection roller 65 rotates, it can drive the first runner 77 to rotate together; a stop bar 78 arranged on the side of the connection block 71 and above the marking liquid spraying tank 72. The stop bars 78 correspond to the connection blocks 71 one by one; a rotating rod 79 rotatably arranged between the two stop bars 78 and parallel to the marking liquid spraying tank 72. The stop bars 78 and the L-shaped connecting rods 75 are arranged in a staggered manner to avoid mutual interference; and second runners 710 respectively arranged on the outer walls at both ends of the rotating rod 79. Fan plates 711 are arranged at intervals along the axial direction on the outer wall of the rotating rod 79. The first runner 77 on the roller shaft 651 is drivingly connected to the corresponding second runner 710 through a belt 712.

[0046] During use, place the automotive windshield to be detected on the fixed arc frame 3 for fixation. Then, start the linear moving member 4. The moving end of the linear moving member 4 will drive the telescopic rod 5 and the support block 6 to move, thereby driving the vertical plate 61 to move. The vertical plate 61 drives the moving column link 62, the detection member 63, the detection roller 65, and the electric push rod 64 to move. Among them, the detection roller 65 contacts the surface of the windshield and detects the curved surface of the windshield, and the detection member 63 detects cracks. When cracks are detected in the windshield, the linear moving member 4 stops moving. At the same time, the telescopic end of the electric push rod 64 drives the link 62 to move downward along the vertical plate 61. The link 62 moves downward and drives the detection member 63 and the detection roller 65 away from the surface of the windshield. At the same time, the link 62 moves downward and drives the connecting block 71 to move downward. The connecting block 71 moves downward and presses the pressing end of the L-shaped pressing member 76, so that the pressing end of the L-shaped pressing member 76 conveys the marking liquid in the marking liquid spraying tank 72 to the nozzle block 74 through the hose 73 and sprays it onto the cracks of the windshield, thereby marking the cracks on the surface of the automotive windshield, facilitating subsequent workers to observe and repair the cracks on the surface of the automotive windshield; after the marking is completed, the telescopic end of the electric push rod 64 will extend, and the detection member 63 and the detection roller 65 will be reset to continue the detection; when the detection roller 65 moves on the surface of the automotive windshield, it will rotate. The rotation of the detection roller 65 drives the first runner 77 to rotate. The first runner 77 drives the second runner 710 to rotate through the belt 712. The second runner 710 drives the fan plate 711 on the rotating rod 79 to rotate, thereby fanning the surrounding air flow and accelerating the drying speed of the marking liquid, avoiding the situation where the marks at the cracks on the surface of the automotive windshield are accidentally wiped off.

[0047] As Figure 7 and Figure 8 shown, in another embodiment of the present invention, a detection device for an automotive windshield is provided, which further includes a wiping mechanism 8; the wiping mechanism 8 includes a moving long block 81 located on the side of the nozzle block 74 away from the detection roller 65. The moving long block 81 is parallel to the nozzle block 74; elastic arc plates 82 are respectively arranged on both sides of the moving long block 81. The elastic arc plates 82 are arc-shaped and are made of a material with a certain elasticity and can rebound after the external force disappears; a limiting block 83 is arranged on the side of the elastic arc plate 82 away from the moving long block 81. The limiting block 83 is connected to the side wall of the L-shaped link 75; an L-shaped short block 84 is arranged at the bottom of the moving long block 81, and a wiping plate 85 is arranged at the end of the L-shaped short block 84 and contacts the outer walls of the two detection rollers 65.

[0048] The wiping mechanism 8 further includes an L-shaped fixing rod 86 provided at the bottom of an elastic arc plate 82, and short rods 87 annularly and spaced apart on the outer wall of the rotating rod 79 and corresponding to the L-shaped fixing rod 86. Circular blocks are provided at the ends of the L-shaped fixing rod 86 away from the elastic arc plate 82 and at the ends of the short rods 87 away from the rotating rod 79, and the circular blocks on the L-shaped fixing rod 86 and the circular blocks on the short rods 87 have overlapping movement trajectories.

[0049] When the rotating rod 79 rotates, it will drive the short rods 87 to rotate together. When the short rods 87 rotate, the circular blocks on the short rods 87 will contact the circular blocks at the ends of the L-shaped fixing rod 86, so that the L-shaped fixing rod 86 moves upward. The upward movement of the L-shaped fixing rod 86 will squeeze the elastic arc plate 82, so that the elastic arc plate 82 deforms. The deformation of the elastic arc plate 82 will cause the moving long block 81 to move, and the movement of the moving long block 81 will drive the wiping plate 85 to move. When the circular blocks on the short rods 87 do not contact the circular blocks on the L-shaped fixing rod 86, the elastic arc plate 82 resets, and then drives the moving long block 81 and the wiping plate 85 to reset. In this way, the reciprocating movement of the wiping plate 85 is realized, so that the wiping plate 85 moves left and right reciprocally and wipes the surface of the detection roller 65, realizing the wiping of the outer surface of the detection roller 65 in the axial direction, wiping more cleanly, and avoiding the interference of the marking liquid adhered to the detection roller 65 during rotation on other marked positions.

[0050] As Figure 7 and Figure 9 As shown, in another embodiment of the present invention, a vehicle windshield detection device is provided, which further includes a cleaning mechanism 9; the cleaning mechanism 9 includes a limit block 91 provided on the side of a vertical plate 61 away from the L-shaped connecting rod 75, and a long rod 92 provided on the limit block 91 and parallel to the connecting rod 62. A brush 93 for cleaning the glass is provided on the side wall of the long rod 92. The surface of the windshield is cleaned by the brush 93, so that the sundries on the surface of the windshield can be removed, avoiding the influence of the sundries on the accuracy of the detection of the detection piece 63 and the detection roller 65.

[0051] In another embodiment of the present invention, the long rod 92 slidably penetrates through the limit block 91, and a through hole matching the long rod 92 is provided on the limit block 91; the cleaning mechanism 9 further includes a cross plate 94 provided at the end of the long rod 92 away from the limit block 91 and opposite to the roller shaft 651 of the corresponding detection roller 65, and a fixed disc 95 provided on the roller shaft 651 of the corresponding detection roller 65. A limit circular plate 96 is provided at the end of the long rod 92 close to the limit block 91. A second spring is provided between the limit circular plate 96 and the limit block 91, and the second spring is sleeved on the long rod 92; a plurality of hemispherical blocks 97 are annularly and spaced apart on the side wall of the fixed disc 95 close to the cross plate 94. A pushing block 98 corresponding to the hemispherical blocks 97 is provided on the cross plate 94, and the movement trajectories of the pushing block 98 and the hemispherical blocks 97 coincide.

[0052] During use, the cleaning mechanism 9 is located on the front side of the detection roller 65 and the detection member 63, and can clean the surface of the windshield before detection, which can greatly reduce the interference caused by impurities adhered to the glass surface. The roller shaft 651 of the detection roller 65 rotates and drives the fixed disc 95 to rotate. The fixed disc 95 rotates and drives the hemispherical block 97 to rotate. The hemispherical block 97 rotates and touches the pushing block 98, so that the pushing block 98 moves in a direction away from the fixed disc 95. The movement of the pushing block 98 drives the long rod 92 to move through the cross plate 94. The movement of the long rod 92 drives the limit circular plate 96 to move. At this time, the second spring is compressed. When the hemispherical block 97 does not contact the pushing block 98, the second spring resets, and then drives the long rod 92, the cross plate 94, the pushing block 98, and the brush 93 to reset. In this way, the reciprocating movement of the brush 93 can clean the sundries on the surface of the automotive windshield, thus avoiding the influence of sundries on the detection accuracy.

[0053] In another embodiment of the present invention, a method for detecting an automotive windshield is provided, including the following steps:

[0054] S1. Place the windshield to be detected on the fixed arc frame 3 for fixation;

[0055] S2. Start the telescopic rod 5 and adjust the positions of the vertical plate 61 and the connecting rod 62 on the support block 6, and make the detection roller 65 contact the surface of the windshield;

[0056] S3. Further start the linear moving member 4, and make the linear moving member 4 drive the telescopic rod 5, the support block 6 and the marking mechanism 7 to move; the support block 6 drives the vertical plate 61 to move. The vertical plate 61 drives the connecting rod 62, the detection member 63 and the electric push rod 64 to move, and the detection roller 65 rotates under the action of friction;

[0057] S4. The detection member 63 detects the cracks on the windshield during movement, and the detection roller 65 detects the curved surface of the windshield during rotation. When a crack is detected, the linear moving member 4 stops moving, and the marking mechanism 7 is driven by the electric push rod 64 to mark the position of the crack;

[0058] S5. After the marking mechanism 7 finishes marking, the electric push rod 64 resets, start the linear moving member 4 and perform the next detection until the detection is completed;

[0059] S51. Start the linear moving member 4 to continue moving. The detection roller 65 rotates and drives the rotating rod 79 in the marking mechanism 7 to rotate. The rotating rod 79 drives the fan plate 711 to rotate, and fans the surrounding air flow, thereby accelerating the drying speed of the marking liquid and avoiding the situation that the mark at the crack on the surface of the automotive windshield is accidentally wiped off;

[0060] S52.
