Technical Field

[0001] The present invention relates to the technical field of machine vision inspection of wine bottles, and in particular to a device and method for detecting wire drawing on the inner wall of a wine bottle. Background Art

[0002] The wire drawing on the inner wall of the wine bottle, commonly known as bird hanging, is one of the common serious defects in the wine bottle manufacturing process that affects food safety. During the filling process in the winery, the wire drawing on the inner wall is easily broken and fallen off by the wine, resulting in glass fibers and glass fragments entering the wine, causing food safety problems.

[0003] The traditional method for detecting wiredrawing on the inner wall of wine bottles is to complete the identification and detection through the side wall inspection of the EBI inspection machine. This detection method may miss very fine wiredrawing on the inner wall and wiredrawing on the inner wall of the patterned area. In particular, for some special-shaped wine bottles that cannot rotate in the EBI, the traditional side wall inspection has a greater chance of missing detection.

[0004] Therefore, in order to solve the above problems, a device for detecting wire drawing on the inner wall of a wine bottle is developed, which can enter the interior of the wine bottle and shoot the inner wall of the wine bottle at an angle to avoid missed detection. Summary of the Invention

[0009] Furthermore, it also includes a rotating mechanism for automatically rotating and moving the mounting bracket. The rotating mechanism includes a rotating part and a shifting post. The rotating part is connected to the left side of the mounting bracket, and the shifting post is connected to the right side of the upper part of the vertical frame.

[0011] Furthermore, it also includes a bottom light, which is connected to the middle position of the top of the placement tray.

[0012] Furthermore, it also includes a guide column and a third spring. The guide column is connected to the upper side of the right part of the toggle frame. The guide column is slidably connected to the mounting frame. The third spring is connected between the guide column and the mounting frame.

[0013] Furthermore, the portions of the clamping members that are close to each other are all arc-shaped.

[0015] Step 1: Control the electric push rod to make the rotating part drive the mounting frame to rotate, then place the wine bottle to be tested on the placement plate, and use the clamping part to clamp the wine bottle to limit the position;

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and examples.

[0032] A device for detecting wire drawing on the inner wall of a wine bottle, such as Figure 1 and Figure 2As shown, it includes a base 1, a placement tray 11, an isolation cover 12, a stand 13, a detection mechanism 2 and a rotating mechanism 3. The top of the base 1 is rotatably connected to the placement tray 11, and the placement tray 11 is used to place wine bottles. The top of the base 1 is connected to the isolation cover 12, and the isolation cover 12 can protect the internal components. The left side of the base 1 is connected to the stand 13, and the stand 13 is provided with a detection mechanism 2 for rotating the angle of the inside of the wine bottle for shooting. The base 1 is provided with a rotating mechanism 3, so that the placement tray 11 can automatically rotate intermittently.

[0033] During the manufacturing process of wine bottles, there may be wire drawing on the inner wall of the bottle body due to process errors. In order to inspect the finished wine bottles, the inspectors can use this device to assist in the inspection work. First, the wine bottle is placed on the placement tray 11, and then the inspection mechanism 2 is used to photograph and inspect the inside of the wine bottle. At the same time, the rotating mechanism 3 needs to be started to make the wine bottle start to rotate intermittently, so that the inspection mechanism 2 can fully photograph the inner wall of the wine bottle, avoid missed inspections, and improve inspection accuracy.

[0034] like Figure 1 、 Figure 3 and Figure 4 As shown, the detection mechanism 2 includes an electric push rod 20, a mounting frame 21, a detection head 22, a toggle frame 23 and a blocking frame 24. The vertical frame 13 is connected to the electric push rod 20, and the telescopic end of the electric push rod 20 is rotatably connected to the mounting frame 21. The right side of the mounting frame 21 is rotatably connected to the detection head 22, and the detection head 22 is used to take pictures and detect the inside of the wine bottle. The right part of the mounting frame 21 is slidably connected to the toggle frame 23, and the upper right side of the vertical frame 13 is connected to the blocking frame 24. The toggle frame 23 can be pushed by the blocking frame 24, and the toggle frame 23 is slidably connected to the detection head 22. The sliding of the toggle frame 23 can drive the detection head 22 to rotate.

[0035] When conducting wire drawing inspection on a wine bottle, first rotate the mounting frame 21 clockwise, then place the wine bottle, and after it is placed stably, rotate the mounting frame 21 counterclockwise to reset it, and then start the electric push rod 20, so that the telescopic end of the electric push rod 20 contracts, thereby driving the mounting frame 21 to move downward. As the mounting frame 21 moves downward, it will drive the toggle frame 23 to move downward. At the same time, the detection head 22 will move downward under the drive of the mounting frame 21, thereby entering the interior of the wine bottle. As the toggle frame 23 continues to move downward and contacts the blocking frame 24, the toggle frame 23 will be pushed by the blocking frame 24 and begin to slide upward, thereby causing the detection head 22 to rotate backward, forming an angle tilt, and then being able to directly photograph the inner wall of the wine bottle, so that the inspection personnel can intuitively observe the inner wall of the wine bottle. During the shooting and inspection process, the inspection personnel need to rotate the placement plate 11 to rotate the wine bottle, so that The detection head 22 can perform a comprehensive inspection of the inner wall of the wine bottle to avoid missed parts. When the inspection is completed, the telescopic end of the electric push rod 20 is controlled to extend and reset, so that the mounting frame 21 starts to move upward and reset, and then the toggle frame 23 is no longer in contact with the blocking frame 24. At this time, the toggle frame 23 will slide downward and reset under the action of its own gravity, so that the detection head 22 rotates forward and resets, which makes it easier for the detection head 22 to follow the mounting frame 21 to move upward and leave the inside of the wine bottle. Finally, the inspected wine bottle is removed, and the above operation is repeated to continuously inspect the wine bottle. In summary, the mounting frame 21 is driven downward by the electric push rod 20, so that the blocking frame 24 pushes the toggle frame 23, and then the toggle frame 23 drives the detection head 22 to rotate, so that the inner wall of the wine bottle can be photographed and inspected, avoiding missed inspections and the inability to intuitively detect wire drawing.

[0036] like Figure 1 and Figure 5 As shown, the rotating mechanism 3 includes a motor 30, a missing gear 31, a spur gear 32, a locking ring 33, a locking member 34, a first spring 35 and a fixed block 36. The motor 30 is connected to the upper right side of the base 1 by bolts, and the missing gear 31 is connected to the output shaft of the motor 30. The spur gear 32 is connected to the placement plate 11, and the toothed portion of the spur gear 32 and the missing gear 31 are meshed with each other. The lower part of the placement plate 11 is connected to the locking ring 33, and the fixing block 36 is connected to the upper left side of the base 1. The locking member 34 is slidably connected to the fixing block 36. The locking member 34 can be engaged with the locking ring 33, so that the placement plate 11 cannot rotate. A first spring 35 is connected between the locking member 34 and the fixing block 36. The left end of the first spring 35 is connected to the fixing block 36, and the right end of the first spring 35 is connected to the locking member 34. The first spring 35 is wound around the locking member 34.

[0037] When the detection head 22 starts to take pictures and detect the inside of the wine bottle, in order to enable the detection head 22 to take a comprehensive picture and detect the inner wall of the wine bottle, the motor 30 can be started, and the output shaft of the motor 30 drives the missing gear 31 to rotate, so that the spur gear 32 starts to rotate, and then the placement plate 11 rotates. The rotation of the placement plate 11 drives the wine bottle to rotate. At this time, the locking ring 33 squeezes the locking member 34, so that the locking member 34 slides to the left, and the first spring 35 is compressed. As the missing gear 31 continues to rotate, the toothed part of the missing gear 31 disengages from the spur gear 32. At this time, the spur gear 32 no longer rotates, that is, one rotation of the missing gear 31 will drive the spur gear 32 to rotate one-third of a circle, that is, 120 degrees, when the spur gear 32 is no longer driven by the missing gear 31, the locking ring 33 will be in a state of no longer squeezing the locking member 34, and the locking member 34 will slide to the right and reset under the action of the first spring 35, thereby locking with the locking ring 33 again, preventing the placement plate 11 from continuing to rotate, causing the wine bottle to fall over. At the same time, the static state of the wine bottle is also conducive to clear shooting and detection by the detection head 22. Afterwards, as the toothed part of the missing gear 31 continues to engage with the spur gear 32, the above operation is repeated. In summary, the missing gear 31 is driven to rotate by the output shaft of the motor 30, thereby achieving the effect of intermittent rotation of the spur gear 32, and then the placement plate 11 drives the wine bottle to rotate intermittently, which is convenient for the detection head 22 to clearly shoot and detect the inner wall of the wine bottle.

[0038] like Figure 1 and Figure 6 As shown, it also includes a rotating mechanism 4, which includes a rotating part 40 and a shifting post 41. The rotating part 40 is connected to the left side of the mounting frame 21, and the shifting post 41 is connected to the upper right side of the vertical frame 13. The shifting post 41 is slidably connected to the rotating part 40. An arc-shaped groove is provided on the rotating part 40, and the rotating part 40 will rotate during the rotation of the shifting post 41.

[0039] When it is necessary to inspect the wine bottle, the telescopic end of the electric push rod 20 is first controlled to continue to extend, so that the rotating member 40 starts to rotate forward under the action of the dial column 41, and then the mounting frame 21 rotates clockwise. At this time, the mounting frame 21 will drive the detection head 22 to move, so that the wine bottle can be placed on the placement tray 11. When the wine bottle is placed, the telescopic end of the electric push rod 20 is controlled to retract, so that the rotating block drives the mounting frame 21 to rotate counterclockwise and reset. Then, as the telescopic rod of the electric push rod 20 continues to retract, it will drive the detection head 22 into the wine bottle for inspection. In summary, through the cooperation of the dial column 41 and the rotating member 40, the mounting frame 21 can rotate automatically, thereby facilitating the quick placement of the wine bottle.

[0040] like Figure 1 and Figure 7As shown, a clamping mechanism 5 is also included, and the clamping mechanism 5 includes a fixing part 50, a second spring 51 and a clamping part 52. Three fixing parts 50 are connected to the top of the placement plate 11, and the fixing parts 50 are all slidably connected to the clamping parts 52. The parts of the clamping parts 52 close to each other are all arc-shaped, which can fit the outer edge of the wine bottle, thereby limiting and clamping the wine bottle. A second spring 51 is connected between the clamping part 52 and the fixing part 50, and the second spring 51 is wound around the clamping part 52. The ends of the second springs 51 close to each other are connected to the clamping part 52, and the ends of the second springs 51 away from each other are connected to the fixing part 50.

[0041] After the bottle is inspected, in order to prevent the bottle from falling during the rotation, it is necessary to clamp and fix the bottle. First, before placing the bottle, it is necessary to pull the clamping members 52 to the side away from each other so that the second spring 51 is compressed. Then, the bottle is placed on the placement plate 11, and the clamping members 52 are released. At this time, the clamping members 52 will slide back to the side close to each other under the action of the second spring 51, and clamp and fix the bottle to prevent the bottle from falling during the rotation. When the bottle inspection is completed, the clamping members 52 will be pulled to the side away from each other so that the second spring 51 is compressed. Then, the bottle is taken out, and the clamping members 52 are released so that the clamping members 52 are completely reset under the action of the second spring 51. In summary, through the cooperation between the clamping members 52 and the second spring 51, the bottle is clamped and fixed to prevent the bottle from falling during the rotation and causing damage to the material.

[0042] like Figure 1 and Figure 7 As shown, a bottom light 6 is also included. The bottom light 6 is connected to the middle position of the top of the placement tray 11. The bottom light 6 is used to illuminate the bottom of the wine bottle, thereby assisting the detection head 22 to photograph and detect the inner wall of the wine bottle.

[0043] When photographing and inspecting the wine bottle, the bottom light 6 needs to be turned on to illuminate the wine bottle so that the inspection head 22 can photograph and inspect the interior of the wine bottle more clearly.

[0044] like Figure 1 and Figure 8 As shown, it also includes a guide column 7 and a third spring 70. The guide column 7 is connected to the upper right side of the toggle frame 23. The guide column 7 is slidably connected to the mounting frame 21. The third spring 70 is connected between the guide column 7 and the mounting frame 21. The top end of the third spring 70 is connected to the mounting frame 21, and the bottom end of the third spring 70 is connected to the guide column 7. The third spring 70 is wound around the guide column 7.

[0045] When the toggle frame 23 is pushed by the blocking frame 24 and starts to slide upward, the guide column 7 will slide upward, thereby compressing the third spring 70. As the toggle frame 23 is no longer pushed by the blocking frame 24, the third spring 70 can make the guide column 7 slide downward and reset, thereby making the toggle frame 23 slide downward and reset. It is no longer necessary to rely on the toggle frame 23's own gravity to reset, making the reset more stable.

[0046] A method for detecting wire drawing on the inner wall of a wine bottle, the method comprising the following steps:

[0047] Step 1: Control the electric push rod 20 so that the rotating member 40 drives the mounting frame 21 to rotate, then place the wine bottle to be tested on the placement plate 11, and use the clamping member 52 to clamp the wine bottle to limit its position;

[0048] Step 2: Next, start the bottom light 6, and then control the electric push rod 20 to make the rotating member 40 drive the mounting frame 21 to rotate and reset, and send the detection head 22 into the interior of the wine bottle for shooting and testing. At the same time, start the motor 30 to make the placement plate 11 rotate intermittently, assisting the detection head 22 to perform comprehensive shooting and testing;

[0049] Step 3: After the test is completed, the motor 30 is turned off, and the electric push rod 20 is controlled to make the detection head 22 leave the interior of the wine bottle. Then, the electric push rod 20 is controlled to make the rotating member 40 drive the mounting frame 21 to rotate, and the wine bottle is taken out;

[0050] Step 4: Finally, control the electric push rod 20 so that the rotating member 40 drives the mounting bracket 21 to rotate and reset.
