Description

Detection system, method and use of patterned transparent detection object

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 2024101054360, filed with the Chinese Patent Office on January 24, 2024, entitled "A detection system, method and use for a transparent detection object with a pattern", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present invention relates to the field of detection devices, and in particular to a detection system, method and application of a transparent detection object with a pattern. Background Art

[0004] Existing inspection systems identify the inspection object mainly by acquiring multiple images of the inspection object's surface, and then determine whether there are defects on the inspection object's surface in the image based on the algorithm. Therefore, there are high requirements for the image acquired of the inspection object, requiring the acquired image to be high-definition and free of other interference factors. It is usually only applicable to inspection objects made of non-transparent materials. For inspection objects made of transparent materials, the transparent material will cause the opposite side of the inspection to display the content of the external environment on the front side of the inspection, so that the image acquired on the front side of the inspection will be subject to other interference factors. Especially for partially transparent bottles or tubes, bottles or tubes generally may have patterns, and the pattern on the opposite side of the inspection will be displayed on the front side of the inspection, thereby obtaining an image with overlapping patterns between the front and back sides of the inspection. Some inspection objects may shake during transportation due to unstable clamping, which may also cause part of the outline of the opposite side of the inspection to appear on the front side of the inspection. When the content of the opposite side of the inspection appears on the front side of the inspection, it interferes with the recognition of the pattern content on the front side of the inspection, resulting in misjudgment.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to propose a detection system for a transparent detection object with a pattern, which uses a clamping gap formed when the clamping synchronous belts are close to each other to clamp the detection object, and the clamping synchronous belts drive the detection object to rotate a specific number of times during the movement process, so that the detection object passes through the lighting channel and is illuminated in a rotating state, and the image acquisition device can obtain a clear picture of the detection object.

[0007] The present invention also provides a method for detecting a transparent detection object with a pattern, which can obtain a clear image of the detection object.

[0008] The present invention also provides a use of a detection system in detecting transparent bottle-shaped objects or tube-shaped objects with patterns.

[0009] To achieve this object, the present invention adopts the following technical solutions:

[0012] The lighting device is installed on the detection base;

[0013] The lighting device is provided with a lighting channel and an external lighting plate. The inner diameter of the lighting channel gradually decreases from large to small, forming a large-diameter opening at the end with the largest inner diameter and a small-diameter opening at the end with the smallest inner diameter. Light sources are respectively provided on the inner walls of multiple sides of the lighting channel. The image acquisition device is arranged at the small-diameter opening. The light source of the external lighting plate is separated from the lighting channel and forms a detection passage. The conveying end of the loading device passes through the detection passage.

[0014] The detection and conveying device is provided with a clamping drive unit; the clamping drive units are installed in pairs on the detection base and are respectively located on both sides of the detection aisle; the clamping drive unit includes: a clamping rotation driver, a clamping driving wheel, a clamping driven wheel and a clamping synchronous belt;

[0016] Preferably, it further comprises: an image acquisition mobile component;

[0017] The output end of the image acquisition moving component is connected to the image acquisition device, and is used to drive the image acquisition device to move so that the lens of the image acquisition device moves through the small-diameter opening.

[0018] It can be optimized to further include: an in-position sensing device;

[0019] The in-position sensing device is communicatively connected to the image acquisition moving component; the image acquisition moving component drives the image acquisition device to move in a resettable manner.

[0020] Optimally, the lighting device includes: a first lighting board, a second lighting board, a third lighting board and the external lighting board;

[0021] The first lighting plate and the second lighting plate are separated to form the lighting channel; the interval between the first lighting plate and the second lighting plate gradually increases, forming a large-diameter opening at the end of the lighting channel with the largest interval, and a small-diameter opening at the end of the lighting channel with the smallest interval; the detection base is installed below the lighting channel; the third lighting plate is arranged above the lighting channel; the light sources of the first lighting plate, the second lighting plate and the third lighting plate are located in the lighting channel.

[0022] Optimally, it further includes: a lifting drive component;

[0023] A plurality of pairs of the clamping drive units are vertically distributed on the detection platform; a pair of the clamping drive units is installed on the detection base;

[0024] The output end of the lifting drive assembly is connected to the detection base of at least one pair of the clamping drive units, and is used to drive the detection base to move up and down, thereby driving the pair of the clamping drive units of the detection base to move up and down.

[0025] Optimally, it further includes: a horizontal drive component;

[0026] The output end of the horizontal drive assembly is connected to the clamping drive unit, and is used to drive the two clamping drive units to move forward and backward relative to each other, thereby driving the offset sections of the pair of clamping drive units to move closer to or away from each other.

[0027] The horizontal drive assembly includes: a clamping head;

[0028] The clamping synchronous belt can be movably limited to the clamping head; the clamping head causes a section of the clamping synchronous belt between the clamping active wheel and the clamping driven wheel to be offset toward the outer ring direction to form an offset section; the offset sections of two adjacent clamping drive units lean against each other to form a clamping gap with a clamping function.

[0029] A method for detecting a patterned transparent detection object comprises the following steps:

[0030] (1) The loading device transfers the patterned and transparent test object to the test table, and the test object is placed in the clamping gap formed by the synchronous belt on both sides of the test aisle;

[0031] (2) The clamping rotation drivers of the clamping drive units on both sides respectively drive the clamping driving wheels to rotate, and drive the clamping synchronous belt to rotate through the clamping driven wheels; the clamping synchronous belts of the clamping drive units on both sides form a rotation speed and drive the test object to move through the large diameter opening of the polishing channel in a rotating state;

[0033] (4) Determine whether there are defects on the surface of the inspection object based on the acquired image of the inspection object.

[0034] Preferably, in step (3), the image acquisition device moves through the small-diameter opening of the lighting channel and then resets, and the image acquisition device moves synchronously with the detection object in one of the movement directions; the image acquisition device acquires the image of the detection object during the movement.

[0035] It can be optimized that in step (1), after the detection object moves past the in-place sensing device, the in-place sensing device feeds back the in-place information to the clamping and rotating driver, and step (2) is executed.

The image acquisition device can obtain a clear picture of the detection object, which solves the problem of poor light-receiving position of the existing detection object, resulting in overlapping patterns on the front and back sides of the transparent surface during image acquisition, causing interference with recognition.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish the described features, without distinction of order or importance. In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0050] As shown in Figures 1-8, a detection system for patterned transparent test objects includes: a detection platform 01, a loading device 02, a lighting device 03, an image acquisition device 04, a detection conveyor device 05, and a detection base 06;

[0051] The conveying end of the loading device 02 passes through the detection platform 01; the image acquisition device 04, the lighting device 03 and the detection and transmission device 05 are respectively installed on the detection platform 01; the detection base 06 is set on the detection platform 01;

[0052] The lighting device 03 is installed on the detection base 06;

[0053] The lighting device 03 is provided with a lighting channel 30 and an external lighting plate 34. The inner diameter of the lighting channel 30 gradually decreases from large to small, forming a large-diameter opening 301 at the end with the largest inner diameter and a small-diameter opening 302 at the end with the smallest inner diameter. Light sources are respectively provided on multiple inner walls of the lighting channel 30. The image acquisition device 04 is disposed at the small-diameter opening 302. The light source of the external lighting plate 34 is separated from the lighting channel 30, forming an inspection passage 303. The conveying end of the loading device 02 passes through the inspection passage 303.

[0054] The detection and conveying device 05 is provided with a clamping drive unit 51; the clamping drive unit 51 is installed in pairs on the detection base 06 and is located on both sides of the detection aisle 303; the clamping drive unit 51 includes: a clamping rotation driver 511, a clamping driving wheel 512, a clamping driven wheel 513 and a clamping synchronous belt 514;

[0055] The output end of the clamping rotation driver 511 is connected to the clamping driving wheel 512, which is used to drive the clamping driving wheel 512 to rotate; the clamping synchronous belt 514 connects the clamping driving wheel 512 and the clamping driven wheel 513 for synchronous rotation; the clamping synchronous belts 514 located on both sides of the detection aisle 303 are close to each other to form a clamping jaw 510 with a clamping function.

[0056] This solution provides a detection system for a transparent detection object with a pattern, which uses a clamping gap formed when the clamping synchronous belts 514 are close to each other to clamp the detection object, and the clamping synchronous belts 514 drive the detection object to rotate a specific number of times during the movement. The detection object passes through the lighting channel 30 in a rotating state and is exposed to light. The image acquisition device 04 can obtain a clear picture of the detection object, solving the problem of poor light-receiving position of the existing detection object, which causes overlapping patterns on the front and back sides of the transparent surface during image acquisition, thereby interfering with recognition.

[0057] The loading device 02 is used to convey the test object. The test object is placed on the conveying end of the loading device 02. The conveying end drives the test object to move through the test aisle 303. The test object moves to the front of the large-diameter opening 301, so that the test object finally stops at the clamping opening 510. When the test object is clamped by the clamping synchronous belt 514 of a pair of clamping drive units 51, the clamping rotation driver 511 can be started. The output end of the clamping rotation driver 511 rotates, driving the clamping active wheel 512. The clamping synchronous belt 514 connects the clamping driven wheel 513 and the clamping active wheel 512 to rotate synchronously, so that the clamping driven wheel 513 also rotates, and then the clamping synchronous belt 514 moves in a straight line between the clamping active wheel 512 and the clamping active wheel 512. Therefore, when the two clamping synchronous belts 514 clamp the test object, they also drive the test object to move; in the pair of clamping drive units 51 Each clamping drive unit 51 is provided with an independent clamping rotation driver 511, and the output parameters of the clamping rotation driver 511 can be adjusted as needed, thereby adjusting the rotation speed and rotation direction of the clamping synchronous belt 514; when the two clamping synchronous belts 514 have the same speed, the detection object can be driven forward in opposite rotation directions; when the speed of one clamping synchronous belt 514 is greater than the speed of the other clamping synchronous belt 514, the clamping synchronous belt 514 with a larger speed can drive the detection object to rotate, so that the detection object passes through the large-diameter opening 301 of the lighting channel 30 in a rotating state. The inner diameter of the lighting channel 30 gradually increases, and the lighting channel 30 has a trumpet-shaped structure; the inspection object is transmitted to a straight position between the inspection channel 303 and the external lighting plate 34 and the large-diameter opening 301; the light sources of the multiple inner walls of the lighting channel 30 illuminate the surface of the inspection object, so that the inspection object can be evenly illuminated in front of the large-diameter opening 301, thereby facilitating the image acquisition device 04 to obtain a clear picture at the small-diameter opening 302; the pattern on the front of the inspection object has the highest brightness and the largest lighting range under the illumination of the large-diameter opening 301, while the pattern on the back of the inspection object close to the external lighting plate 34 has low brightness and a small area, so that the pattern on the front of the inspection object and the pattern on the back of the inspection object form a large luminosity difference, and the pattern on the back of the inspection object will not appear on the front of the inspection object; therefore, the clearest picture can be obtained at the small-diameter opening 302. Image recognition device 09 is a well-known device with image recognition capabilities, such as a computer, motherboard, mobile phone, tablet computer, etc.; the image recognition method is well-known and mainly depends on the software installed in image recognition device 09. For example, image recognition device 09 can preset defect characteristics, receive images captured by image acquisition device 04, and then identify whether the content in the image is the same or similar to the preset characteristics, thereby determining whether the inspection object has defects. Of course, image recognition device 09 may also have certain image processing capabilities, such as decolorizing the image and determining whether the inspection object has defects based on the grayscale depth.The image recognition device 09 receives the image acquired by the image acquisition device 04 and determines whether there are defects in the inspection object; and the lighting channel 30 of this solution has the highest brightness and the largest and most uniform lighting range when illuminating the pattern on the front of the inspection object, while the pattern on the back of the inspection object close to the external lighting plate 34 has low brightness and a small area, so the pattern on the back of the inspection object will not appear on the front of the inspection object, thereby solving the problem that the existing inspection object is unevenly illuminated, causing the patterns on the front and back sides of the transparent surface to overlap when acquiring the image, thereby interfering with recognition.

[0058] More specifically, the clamping drive units 51 are arranged in pairs, and each clamping drive unit 51 is correspondingly provided with a clamping active wheel 512 and a clamping driven wheel 513, and the clamping active wheel 512 and the clamping driven wheel 513 are connected in synchronous rotation by a clamping synchronous belt 514; the clamping active wheel 512 of one or two of the clamping drive units 51 is installed on the output end of the clamping rotation driver 511; when the detection object is clamped by the clamping synchronous belt 514 of a pair of clamping drive units 51, the clamping rotation driver 511 can be started, and the output end of the clamping rotation driver 511 rotates to drive the clamping active wheel 512, and the clamping synchronous belt 514 connects the clamping driven wheel 513 and the clamping active wheel 512 in synchronous rotation, so that the clamping driven wheel 513 also rotates, thereby causing the clamping synchronous belt 514 to be moved between the clamping active wheel 512 and the clamping active wheel 512. The segments move in a straight line, so that when the two clamping synchronous belts 514 clamp the inspection object, they also drive the inspection object to move; and, each clamping drive unit 51 in a pair of clamping drive units 51 is provided with an independent clamping rotation driver 511, and the output parameters of the clamping rotation driver 511 can be adjusted as needed, thereby adjusting the rotation rate and rotation direction of the clamping synchronous belt 514; when the two clamping synchronous belts 514 have the same speed, the inspection object can be driven forward when the rotation directions are opposite; when the speed of a clamping synchronous belt 514 is greater than the speed of the other clamping synchronous belt 514, the clamping synchronous belt 514 with a larger speed can drive the inspection object to rotate, so that the inspection object passes through the large-diameter opening 301 of the lighting channel 30 in a rotating state, so that the detection device can capture multiple pictures of the inspection object when it rotates, thereby improving the accuracy of defect detection.

[0059] The clamping rotation driver 511 is a well-known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0060] Among them, the loading device 02 is a well-known mechanism with a driving and moving function, such as a conveyor belt structure, a conveyor roller structure, a conveyor robot arm, a conveyor cart, etc., as long as it can convey the inspection object to pass through the large-diameter opening 301.

[0061] Optimally, it further includes: an image acquisition mobile component 07;

[0062] The output end of the image acquisition moving component 07 is connected to the image acquisition device 04 , and is used to drive the image acquisition device 04 to move, so that the lens of the image acquisition device 04 moves through the small-diameter opening 302 .

[0063] The position of the image acquisition device 04 can be fixed or can be adjusted after being disassembled as needed; in the most preferred embodiment, the image acquisition device 04 is movable; the image acquisition moving component 07 is a well-known mechanism with a driving and moving function, such as a cylinder, a moving trolley, a combination of a screw and a motor, a manipulator structure, etc.; in this way, the image acquisition moving component 07 can drive the image acquisition device 04 to move, thereby driving the lens of the image acquisition device 04 to move through the small-diameter opening 302; in this solution, the lighting device 03 has evenly distributed the light on the inspection object, that is, the position of the lighting is fixed; the images may overlap at a certain angle, but not at a certain angle; and combined with the inspection object passing through the large-diameter opening 3 in a rotating state. 01. During the straight-line transmission, the inspection object can face multiple surfaces toward the image acquisition device 04. The image acquisition device 04 can acquire multiple surfaces of the inspection object, thereby improving the detection accuracy. When the image acquisition device 04 passes through the small-diameter opening 302, the image acquisition device 04 can acquire images of the inspection object at different positions of the small-diameter opening 302, and acquire images from more angles, thereby improving the accuracy of intelligent recognition and the recognition tolerance rate. For example, if there is pattern overlap in one image but not in another, more images can be analyzed to determine whether it is a defect or whether there is pattern overlap. This solves the problem of incomplete and inaccurate detection caused by the limited or discontinuous rotation angle of the inspection object in the existing inspection device.

[0064] It can be further optimized to further include: an in-position sensing device 08;

[0065] The in-position sensing device 08 is communicatively connected to the image acquisition moving component 07; the image acquisition moving component 07 drives the image acquisition device 04 to move in a resettable manner.

[0066] A position sensing device 08 can be set at any position in the detection device. The position sensing device 08 is in communication with the image acquisition mobile component 07. When the position sensing device 08 senses that the image acquisition mobile component 07, the detection object, or other preset mechanisms are in position or passing through, the position information can be fed back to the image acquisition mobile component 07. The image acquisition mobile component 07 mainly drives the image acquisition device 04 to move through the small-diameter opening 302. When the image acquisition mobile component 07 receives the position information, the image acquisition mobile component 07 responds and starts, thereby driving the image acquisition device 04 to move, thereby causing the image acquisition device 04 to move in the same direction as the detection object when it passes through the detection aisle 303. The detection object does not need to stay in the detection aisle 303 for a long time, thereby shortening the detection time of the detection object. Moreover, since the image acquisition device 04 captures the image of the detection object in the process of moving through the small-diameter opening 302, the light-receiving position of the detection object changes during the movement. Therefore, the image acquisition device 04 can capture images from multiple angles under the premise of uniform lighting, which can not only improve the detection tolerance rate, but also improve the detection accuracy and shorten the detection residence time. Thereafter, the image acquisition moving component 07 drives the image acquisition device 04 to move in a resettable manner, thereby resetting the position of the image acquisition device 04 to facilitate subsequent identification of the next detection object.

[0067] Among them, the communication connection method here refers to the communication between connected devices through signal transmission interaction, which can be divided into wired connection and wireless connection; wired connection includes conventional data cable connection; wireless connection includes conventional WiFi, Bluetooth, infrared, NFC, etc.

[0068] Optimally, the lighting device 03 includes: a first lighting board 31, a second lighting board 32, a third lighting board 33 and the external lighting board 34;

[0069] The first lighting plate 31 and the second lighting plate 32 are separated to form the lighting channel 30; the interval between the first lighting plate 31 and the second lighting plate 32 gradually increases, and a large-diameter opening 301 is formed at the end of the lighting channel 30 where the interval is largest, and a small-diameter opening 302 is formed at the end where the interval is smallest; the detection base 06 is installed below the lighting channel 30; the third lighting plate 33 is arranged above the lighting channel 30; the light sources of the first lighting plate 31, the second lighting plate 32 and the third lighting plate 33 are located in the lighting channel 30.

[0070] Specifically, the first lighting plate 31 and the second lighting plate 32 are separated to form a lighting channel 30; the third lighting plate 33 is arranged above the first lighting plate 31 and the second lighting plate 32, so as to cover the opening above the lighting channel 30; the first lighting plate 31 and the second lighting plate 32 are arranged below the detection base 06, so as to cover the opening below the lighting channel 30; at the same time, the interval between the first lighting plate 31 and the second lighting plate 32 gradually increases from one end to the other end, so that the inner diameter of the lighting channel 30 gradually increases, and the lighting channel 30 has a trumpet-shaped structure, and the trumpet-shaped structure has a large-diameter opening 301 with a relatively large inner diameter and a small-diameter opening 302 with a relatively small inner diameter; the light sources of the first lighting plate 31, the second lighting plate 32 and the third lighting plate 33 are arranged in the lighting channel 30; and the external lighting plate 34 is arranged at a distance From the position of the lighting channel 30, a detection channel 303 is formed between the two; the detection object is transmitted to the straight position passing through the detection channel 303 and located between the external lighting plate 34 and the large-diameter opening 301; at this time, an image acquisition device 04 can be set at the small-diameter opening 302; the image acquisition device 04 acquires the image of the detection object facing the small-diameter opening 302; at this time, since the interval between the first lighting plate 31 and the second lighting plate 32 gradually increases, the first lighting plate 31 and the second lighting plate 32 are equivalent to being inclined toward the detection object, so the first lighting plate 31 can emit the light source in an inclined direction to one side of the image to be imaged, and the second lighting plate 32 can emit the light source in an inclined direction to the other side of the image to be imaged; the third lighting plate 33 and the detection base 06 can block the light from being exposed from the upper and lower sides of the lighting channel 30, Thus, it is avoided that the light source is emitted to the non-detection surface; in this way, the surface of the detection object is illuminated by the first lighting plate 31, the second lighting plate 32 and the third lighting plate 33, so that the detection object can be evenly illuminated toward the front of the large-diameter opening 301, so that it is convenient for the image acquisition device 04 to obtain a clear picture at the small-diameter opening 302; at the same time, the small-diameter opening 302, the large-diameter opening 301 and the external lighting plate 34 are distributed in sequence, and the external lighting plate 34 will also emit light to the back of the detection object. The back of the detection object is illuminated, and part of the light is projected on the back of the front pattern; in this way, the detection object is The pattern on the surface has the highest brightness and the largest lighting range under the illumination of the first lighting plate 31, the second lighting plate 32 and the third lighting plate 33, while the pattern on the back of the detection object close to the external lighting plate 34 has low brightness and a small area. Therefore, there is a large luminosity difference between the pattern on the front of the detection object and the pattern on the back of the detection object, and the pattern on the back of the detection object will not appear on the front of the detection object; therefore, the clearest image can be obtained at the small-diameter opening 302, which solves the problem that the existing detection object is unevenly illuminated, causing the patterns on the front and back sides of the transparent surface to overlap when acquiring the image, thereby interfering with recognition.

[0071] The first polishing plate 31 and the second polishing plate 32 form an angle of 30-90 degrees.

[0072] The angle between the first lighting plate 31 and the second lighting plate 32 can be preferably 30-90°; within this angle range, the light source in the lighting channel 30 has a better effect on uniformity of lighting the inspection object and preventing pattern overlap; especially when the angle between the first lighting plate 31 and the second lighting plate 32 is 60°, the performance is optimal.

[0073] Optimally, it further includes: a lifting drive component 52;

[0074] A plurality of pairs of the clamping drive units 51 are vertically distributed on the detection platform 01; a pair of the clamping drive units 51 is installed on the detection base 06;

[0075] The output end of the lifting drive assembly 52 is connected to the detection base 06 of at least one pair of the clamping drive units 51, and is used to drive the detection base 06 to move up and down, thereby driving the pair of the clamping drive units 51 of the detection base 06 to move up and down.

[0076] The lifting drive assembly 52 includes: a nut seat 521, a lifting screw rod 522 and a lifting driver 523;

[0077] The nut seat 521 is installed on part of the detection base 06; the nut seat 521 is provided with a threaded hole 5211; the lifting screw 522 is threadedly engaged with the threaded hole 5211; the lifting driver 523 is connected to the lifting screw 522, and is used to drive the lifting screw 522 to rotate relative to the nut seat 521, so that the detection base 06 is lifted and lowered along the length direction of the lifting screw 522, driving a pair of the clamping drive units 51 to lift and move.

[0078] The lifting drive assembly 52 of this solution can be replaced by a known mechanism with a lifting function. In the most preferred embodiment, a combination of a nut seat 521 and a lifting screw 522 can be used to achieve this. Specifically, the nut seat 521 is mounted on the detection base 06, and the lifting screw 522 is threadedly engaged with the threaded hole 5211 of the nut seat 521. The rotation of the lifting screw 522 can drive the external thread structure of the lifting screw 522 and the internal thread structure of the threaded hole 5211 to rotate relative to each other, causing the nut seat 521 to rise and fall relative to the lifting screw 522, thereby driving the detection base 06 connected to the nut seat 521 to rise and fall, and further driving the pair of clamping drive units 51 on the detection base 06 to rise and fall, thereby adjusting the height position of the clamping jaws 510 of the pair of clamping drive units 51 relative to the detection object. The lifting drive 523 can be an adjustment member for manually driving the lifting screw 522 to rotate, or it can be a mechanism for mechanically and automatically adjusting the rotation of the lifting screw 522, such as a motor.

[0079] The lifting drive assembly 52 includes: a synchronous rotating wheel 524 and a synchronous rotating belt 525;

[0080] The nut seats 521 are installed at multiple positions of the detection base 06, and multiple nut seats 521 are threadedly matched with the lifting screw 522; some of the synchronous rotating wheels 524 are installed on the lifting screw 522, and the synchronous rotating wheels 524 are fixed in synchronous rotation with the lifting screw 522; the synchronous rotating belt 525 connects multiple synchronous rotating wheels 524 in synchronous rotation; the lifting driver 523 is connected to one of the lifting screws 522 or the synchronous rotating wheels 524.

[0081] The present solution preferably provides nut seats 521 at multiple positions of the detection base 06, so that lifting screws 522 are installed at multiple positions of the detection base 06; multiple lifting screws 522 are provided with synchronous rotating wheels 524, that is, some synchronous rotating wheels 524 can be installed on multiple lifting screws 522, some synchronous rotating wheels 524 can only be used to tension the synchronous rotating belt 525 without being connected to the lifting screw 522, and some can only be connected to the lifting driver 523; the synchronous rotating belt 525 connects the multiple synchronous rotating wheels 524 for synchronous rotation; in this regard, driving a single lifting screw 522 or a single synchronous rotating wheel 524 to rotate can drive the lifting screw 522 to rotate, and the synchronous rotating wheels 524 of other lifting screws 522 are driven to rotate through the synchronous rotating belt 525, so that the lifting screws 522 rotate synchronously, and then the multiple lifting screws 522 are respectively lifted and lowered synchronously on their nut seats 521; the provision of multiple lifting screws 522 can make the force on the detection base 06 more uniform and the lifting more stable.

[0082] The lifting driver 523 is a turntable; the turntable is installed on one of the synchronous rotating wheels 524 or the lifting screw 522, and is used to drive one of the synchronous rotating wheels 524 or the lifting screw 522 to rotate.

[0083] The turntable can facilitate manual direct adjustment of the synchronous rotating wheel 524 or the lifting screw 522, thereby directly adjusting the height of the detection base 06, and then adjusting the height of the clamping drive unit 51, realizing manual rapid and accurate adjustment of the height of the clamp 510, saving the electric drive structure.

[0084] Also included: a lifting guide assembly 54;

[0085] The lifting guide assembly 54 includes a lifting guide rail 541 and a lifting guide slider 542;

[0086] The lifting guide slider 542 is installed on the lifting guide rail 541 in a liftable manner; the lifting guide slider 542 is installed on the detection base 06 to drive the detection base 06 to move up and down along the length direction of the lifting guide rail 541.

[0087] Any number of lifting guide rails 541 can be fixed at any position, such as on a workbench or a wall; the lifting guide slider 542 is installed on the lifting guide rail 541 and can be lifted and lowered along the length direction of the lifting guide rail 541, thereby driving the detection base 06 to be lifted and lowered along the length direction of the lifting guide rail 541, thereby providing a guiding effect for the detection base 06, ensuring the lifting stability of the detection base 06, and making the lifting and lowering adjustment of the clamp 510 smoother.

[0088] Optimally, it further includes: a horizontal driving component 53;

[0089] The output end of the horizontal drive assembly 53 is connected to the clamping drive unit 51 and is used to drive the two clamping drive units 51 to move forward and backward relative to each other, thereby driving the offset sections 5140 of the pair of clamping drive units 51 to move closer to or away from each other.

[0090] The horizontal driving assembly 53 includes: a clamping head 531;

[0091] The clamping synchronous belt 514 can be movably limited to the clamping head 531; the clamping head 531 causes the clamping synchronous belt 514 to be offset toward the outer circle at a section between the clamping active wheel 512 and the clamping driven wheel 513 to form an offset section 5140; the offset sections 5140 of two adjacent clamping drive units 51 lean against each other and form a clamping mouth 510 with a clamping function.

[0092] A section of the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 is limited to the clamping head 531. The clamping head 531 can cause the clamping synchronous belt 514 between the clamping driving wheel 512 and the clamping driven wheel 513 to shift toward the outer ring direction of the clamping synchronous belt 514, thereby causing the offset section to deviate from the straight line formed by the wheel surfaces of the clamping driving wheel 512 and the clamping driven wheel 513. The clamping head 531 also has a tightening effect on the clamping synchronous belt 514. When the test object is transmitted to the nip formed between the two clamping synchronous belts 514, the output end of the clamping rotation driver 511 drives the clamping active wheel 512 to rotate, thereby driving the clamping synchronous belt 514 to rotate; when the clamping synchronous belt 514 rotates, the clamping synchronous belt 514 clamps the test object to move and rotate, and when a speed difference is formed between the two clamping synchronous belts 514, the test object can be rotated one or more times, which can be determined by the distance that the clamping head 531 causes the clamping synchronous belt 514 to deviate toward the outer ring; the speed difference between the clamping synchronous belts 514 can be achieved according to the output parameters of the clamping rotation driver 511 of the corresponding clamping drive unit 51.

[0093] The horizontal drive assembly 53 further includes: a clamping and moving driver 532;

[0094] The output end of the clamping movement driver 532 is connected to the detection base 06 or the clamping head 531 , and is used to drive the detection base 06 or the clamping head 531 to move, thereby driving the offset section 5140 to move.

[0095] The two offset segments 5140 can move relative to each other, either one moving toward the other or both moving toward each other. When the two offset segments 5140 move toward each other, they abut to form a clamping opening 510. The size of the clamping opening 510 can be adjusted by the clamping motion actuator 532, thereby adaptively clamping objects of varying sizes.

[0096] In one embodiment, the clamping movement driver 532 can drive the detection base 06 to move, thereby driving the clamping rotation driver 511, the clamping driving wheel 512, the clamping driven wheel 513, and the clamping timing belt 514 to move synchronously, thereby moving the offset section 5140 of the clamping timing belt 514 to adjust the size of the clamping opening 510. In one embodiment, the clamping movement driver 532 can only drive the clamping head 531 to move, thereby driving the offset section 5140 to move via the clamping head 531 to adjust the size of the clamping opening 510.

[0097] The clamping head 531 is provided with a clamping limiting groove 5311 ; the offset section 5140 can be relatively movably limited in the clamping limiting groove 5311 .

[0098] The clamping limit groove 5311 can limit the movement of a section of the clamping synchronous belt 514, thereby ensuring that the clamping synchronous belt 514 can move the section between the clamping driving wheel 512 and the clamping driven wheel 513 along the length of the clamping limit groove 5311 when rotating. This provides a guide for the movement of this section of the clamping synchronous belt 514, ensuring that the detection object can move along the length of the clamping limit groove 5311 when clamped, thereby improving movement stability. At the same time, when the clamping head 531 moves, it can drive the offset section 5140 to move toward the detection object through the clamping limit groove 5311, thereby narrowing the clamping gap 510 formed by the clamping synchronous belt 514, thereby ensuring that the clamping synchronous belt 514 is always confined within the clamping limit groove 5311 and is not easily dislodged.

[0099] The clamping and moving driver 532 includes a clamping and driving seat 5321 and a clamping and driving screw 5322;

[0100] The clamping drive screw 5322 is rotatably mounted on the clamping drive seat 5321 ; the clamping head 531 or the detection base 06 is threadedly engaged with the clamping drive screw 5322 ; the rotation of the clamping drive screw 5322 drives the clamping head 531 or the detection base 06 to move.

[0101] The clamping movement driver 532 of this solution can be a well-known mechanism with a driving and moving function, such as a mobile trolley, a conveyor belt structure, a robotic arm, etc., as long as it can drive the clamping drive unit 51 or the clamping head 531 to move. This solution preferably uses the clamping drive screw 5322 and the clamping drive seat 5321 to cooperate as the clamping movement driver 532; the clamping drive screw 5322 is rotatably mounted on the clamping drive seat 5321, and when the clamping drive screw 5322 is rotated, the threaded structure between the clamping drive screw 5322 and the clamping head 531 (or the detection base 06) moves relative to each other; the movement of the clamping head 531 will drive the offset section 5140 to move, causing the offset section 5140 to move relative to the clamping mouth 510 to open or contract; or the detection base 06 drives the clamping drive unit 51 to move as a whole, thereby driving the offset section 5140 to move, causing the offset section 5140 to move relative to the clamping mouth 510 to open or contract.

[0102] The clamping drive screw 5322 is provided with a first drive thread segment 53221 and a second drive thread segment 53222 in opposite directions;

[0103] The first driving thread segment 53221 is threadedly engaged with the clamping head 531 or the detection base 06 of one of the clamping synchronous belts 514 , and the second driving thread segment 53222 is threadedly engaged with the clamping head 531 or the detection base 06 of the other clamping synchronous belt 514 .

[0104] In this solution, a single clamping drive screw 5322 can be used to drive the two clamping heads 531 (or the detection base 06) to move relative to each other, thereby driving the clamping opening 510 formed by the two clamping synchronous belts 514 to open or contract through a single drive source. The rotation of the clamping drive screw 5322 can be manually adjusted or mechanically automatically adjusted (for example, driven by a motor); the rotation of the clamping drive screw 5322 drives the first drive thread segment 53221 and the second drive thread segment 53222 to rotate; and since the first drive thread segment 53221 and the second drive thread segment 53222 are in opposite directions to each other, that is, one segment is a right-handed thread and the other segment is a left-handed thread; in this way, when the clamping drive screw 5322 rotates clockwise, the two clamping heads 531 (or the detection base 06) can be driven to move toward each other, thereby driving the clamping synchronous belt 514 to move toward each other until the clamp 510 contracts; when the clamping drive screw 5322 rotates counterclockwise, the two clamping heads 531 (or the detection base 06) can be driven to move back to back, thereby driving the clamping synchronous belt 514 to move toward each other until the clamp 510 opens.

[0105] The horizontal driving assembly 53 may further include: a clamping guide rod 533;

[0106] Both ends of the clamping guide rod 533 are respectively movably mounted on the clamping heads 531 connected to different clamping synchronous belts 514 , and the clamping heads 531 move along the length direction of the clamping guide rod 533 .

[0107] One end of the clamping guide rod 533 can be relatively movably connected to one of the clamping heads 531, and the other end of the clamping guide rod 533 can be relatively movably connected to the other clamping head 531; in this way, when the two clamping heads 531 (or the detection base 06) move toward or away from each other, the clamping head 531 (or the detection base 06) can drive the offset section 5140 to move along the length direction of the clamping guide rod 533, so that the clamping synchronous belts 514 of the two clamping drive units 51 move in the same plane, which can fix the clamping jaws 510 in a specific position and maintain clamping stability.

[0108] A method for detecting a patterned transparent detection object comprises the following steps:

[0109] (1) The loading device 02 transfers the patterned and transparent test object to the test table 01, and the test object is placed in the clamping opening 510 formed by the clamping synchronous belt 514 on both sides of the test aisle 303;

[0110] The loading device 02 is used to transport the test object. The test object is placed on the conveying end of the loading device 02. The conveying end drives the test object to move through the test aisle 303. The test object moves to the front of the large-diameter opening 301, so that the test object finally stops at the clamping opening 510.

[0111] (2) The clamping rotation drivers 511 of the clamping drive units 51 on both sides respectively drive the clamping driving wheels 512 to rotate, and drive the clamping synchronous belts 514 to rotate through the clamping driven wheels 513; the clamping synchronous belts 514 of the clamping drive units 51 on both sides form a rotational speed and drive the inspection object to move through the large diameter opening 301 of the polishing channel 30 in a rotating state;

[0112] When the detection object is clamped by the clamping synchronous belt 514 of the pair of clamping drive units 51, the clamping rotation driver 511 can be started, and the output end of the clamping rotation driver 511 rotates to drive the clamping active wheel 512. The clamping synchronous belt 514 connects the clamping driven wheel 513 and the clamping active wheel 512 to rotate synchronously, so that the clamping driven wheel 513 also rotates, thereby causing the clamping synchronous belt 514 to move in a straight line between the clamping active wheel 512 and the clamping active wheel 512. Therefore, when the two clamping synchronous belts 514 clamp the detection object, they also drive the detection object to move; in the pair of clamping drive units 51 Each clamping drive unit 51 is provided with an independent clamping rotation driver 511, and the output parameters of the clamping rotation driver 511 can be adjusted as needed, thereby adjusting the rotation speed and rotation direction of the clamping synchronous belt 514; when the two clamping synchronous belts 514 have the same speed, the detection object can be driven forward in opposite rotation directions; when the speed of one clamping synchronous belt 514 is greater than the speed of the other clamping synchronous belt 514, the clamping synchronous belt 514 with a larger speed can drive the detection object to rotate, so that the detection object passes through the large-diameter opening 301 of the lighting channel 30 in a rotating state.

[0113] (3) The multiple inner side walls of the lighting channel 30 and the external lighting plate 34 respectively emit light to two opposite sides of the detection object, and the image acquisition device 04 at the small diameter opening 302 of the lighting channel 30 acquires the image of the detection object;

[0114] The inner diameter of the lighting channel 30 gradually increases, and the lighting channel 30 has a trumpet-shaped structure; the inspection object is transmitted to a straight position between the inspection channel 303 and the external lighting plate 34 and the large-diameter opening 301; the light sources of the multiple inner walls of the lighting channel 30 illuminate the surface of the inspection object, so that the inspection object can be evenly illuminated in front of the large-diameter opening 301, thereby facilitating the image acquisition device 04 to obtain a clear picture at the small-diameter opening 302; the pattern on the front of the inspection object has the highest brightness and the largest lighting range under the illumination of the large-diameter opening 301, while the pattern on the back of the inspection object close to the external lighting plate 34 has low brightness and a small area, so that the pattern on the front of the inspection object and the pattern on the back of the inspection object form a large luminosity difference, and the pattern on the back of the inspection object will not appear on the front of the inspection object; therefore, the clearest picture can be obtained at the small-diameter opening 302.

[0115] (4) Determine whether there are defects on the surface of the inspection object based on the acquired image of the inspection object.

[0116] Image recognition device 09 is a well-known device with image recognition capabilities, such as a computer, motherboard, mobile phone, tablet computer, etc.; the image recognition method is well-known and mainly depends on the software installed in image recognition device 09. For example, image recognition device 09 can preset defect characteristics, receive images captured by image acquisition device 04, and then identify whether the content in the image is the same or similar to the preset characteristics, thereby determining whether the inspection object has defects. Of course, image recognition device 09 may also have certain image processing capabilities, such as decolorizing the image and determining whether the inspection object has defects based on the grayscale depth.

[0117] Optionally, in step (3), the image acquisition device 04 moves through the small-diameter opening 302 of the lighting channel 30 and then resets, and the image acquisition device 04 moves synchronously with the detection object in one of the movement directions; the image acquisition device 04 acquires the image of the detection object during the movement.

[0118] In the process of driving the image acquisition device 04 to move in a resettable manner, the image acquisition device 04 will move synchronously with the conveying end of the loading device 02 in one of the moving directions, so that the speed of the image acquisition device 04 in one of the moving directions is the same as the conveying speed of the loading device 02 driving the detection object. The image acquisition device 04 and the loading device 02 are relatively stationary. The image acquisition device 04 can capture the entire process of the detection object passing through the large-diameter opening in the rotating state, thereby improving the detection accuracy. In practical applications, the rotation speed of the detection object driven by the clamp can be calculated based on the production capacity of the entire line and the specification parameters of the detection object. Then, based on the rotation speed of the detection object and the forward movement speed, the required movement distance of the detection object for one and a half circles (or a specific number of circles) is calculated. Then, based on the image acquisition width set by the image acquisition device 04, the camera frame rate required for the detection object to move a specific number of circles is calculated, and then the frame rate parameters of the image acquisition device 04 are modified in real time to achieve the detection object capturing the entire detection surface within the limited stroke.

[0119] It can be optimized that in step (1), after the detection object moves past the in-position sensing device 08, the in-position sensing device 08 feeds back the in-position information to the clamping and rotating driver 511, and step (2) is executed.

[0120] The in-position sensing device 08 is communicatively connected to the image acquisition mobile component 07. When the in-position sensing device 08 senses that the image acquisition mobile component 07, the detection object, or other preset mechanisms therein are in position or passing through, the in-position information can be fed back to the image acquisition mobile component 07. The image acquisition mobile component 07 mainly drives the image acquisition device 04 to move through the small-diameter opening 302. When the image acquisition mobile component 07 receives the in-position information, the image acquisition mobile component 07 responds and starts, thereby driving the image acquisition device 04 to move, and then the image acquisition device 04 moves in the same direction as the detection object when the detection object passes through the detection aisle 303. The detection object does not need to stay in the detection aisle 303 for a long time, thereby shortening the detection time of the detection object. Moreover, since the image acquisition device 04 acquires the image of the detection object in the process of moving through the small-diameter opening 302, the light-receiving position of the detection object changes during the movement. Therefore, the image acquisition device 04 can acquire images from multiple angles under the premise of uniform lighting, which can not only improve the detection tolerance rate, but also improve the detection accuracy and shorten the detection residence time. Thereafter, the image acquisition moving component 07 drives the image acquisition device 04 to move in a resettable manner, thereby resetting the position of the image acquisition device 04 to facilitate subsequent identification of the next detection object.

[0121] A detection system is used for detecting transparent bottle-shaped or tube-shaped objects with patterns. The detection system is the above-mentioned detection system for transparent objects with patterns, or the detection system executes the above-mentioned detection method for transparent objects with patterns.
