Description

Visual inspection system

Technical Field

The invention relates to a visual inspection system, in particular to a visual inspection system for a row of objects, which is used for solving the problem that side wall flaws in the row of objects cannot be detected and improving the inspection efficiency of the visual inspection system.

Background

In general, in order to facilitate single use and storage of liquids such as artificial tears, physiological saline, and trace amounts of pharmaceutical agents, tandem packaging is often used. The bottles are made of light-transmitting plastic materials, each bottle contains a trace amount of liquid solution, and the bottles are connected with each other and arranged in a row. However, such products may be subject to abnormalities such as foreign matter in the bottle, abnormal amounts of liquid, or discoloration of the solution when the liquid solution is filled, and thus it is necessary to perform abnormality detection manually or with the aid of a visual detection instrument. In addition, the abnormal conditions of products such as outer bottle black spots, bottle cap white heads, bottle body burrs or water seepage at the twist cap positions are also aimed at.

Although the speed of detection is facilitated by the aid of visual inspection instruments. However, when the conventional visual inspection apparatus detects an abnormality, image sampling analysis is used. For a partial area of the row of objects, for example, a close-fitting position of two adjacent bottle bodies, effective image sampling analysis cannot be performed. In other words, when a flaw exists in the dead angle of the image sampling, the conventional visual inspection apparatus cannot detect the flaw or may cause erroneous judgment. Finally, the problem is still solved with manual assistance, which is time-consuming and labor-consuming.

In view of the foregoing, it is necessary to provide a visual inspection system for a row of objects, in which the bending module operates the corresponding angle of the row of objects with respect to the inspection module, so as to effectively inspect the defects occurring on the sidewall of the row of objects, and further improve the inspection performance of the visual inspection system, so as to solve the defects of the prior art.

Disclosure of Invention

The invention aims to provide a visual inspection system for inspecting a row of objects. Because the two adjacent bottles of the continuous-row objects are connected by the elastic connecting piece, the visual detection system drives the continuous-row objects through the bending module, so that the two adjacent bottles form a bending angle to expose the side walls of the two bottles, the detection module is used for detecting the side walls, the problem that the two adjacent bottles cannot be detected that the two adjacent bottles are abnormal on the side walls is solved, the requirement of manual visual detection is eliminated, and the detection efficiency is effectively improved. Furthermore, when the bending module drives the connecting objects to form the bending angles between 150 degrees and 170 degrees between two adjacent bottle bodies, the detection module is facilitated to detect, and the elastic connecting piece is prevented from being broken or the bottle bodies are prevented from being separated due to excessive bending.

Another object of the present invention is to provide a visual inspection system for inspecting a row of objects. The driving of the row of articles forms the bending modules of the bending angles of the two adjacent bottle bodies, which can be realized by a transmission track, for example. The design of the transmission track can drive the continuous objects to form convex arc sides to be opposite to the detection module during transmission, so that visual detection of the side wall between two adjacent bottles is realized. In addition, when the transmission track is designed into an S-shaped transmission track, the visual detection of two opposite sides of the objects in the row can be completed together by arranging the detection modules.

It is still another object of the present invention to provide a visual inspection system for inspecting a row of objects. The driving of the row of articles forms the bending modules of the bending angles of the two adjacent bottle bodies, which can be realized by an automatic mechanical clamping arm. The arm is clamped to clamp the continuous objects, and bending operation, standing operation, lying operation, rotating operation or oscillating operation is carried out, so that the continuous objects can be driven to face the detection module at the convex arc side, and visual detection of the side wall between two adjacent bottle bodies is realized. The clamping arm can further clamp the objects in the row to rotate 180 degrees horizontally and then bend reversely, and the visual detection of the two opposite sides of the objects in the row can be completed by matching with the detection module. On the other hand, the visual detection system can integrate other detection items such as the bottom surface, the horizontal surface, the vertical surface and the vibration post, so that the comprehensive automatic detection of the continuous objects is realized, and the defect that the defect is not detected and the product yield is prevented from being influenced.

In order to achieve the above-mentioned objective, the present invention provides a visual inspection system for inspecting a row of objects, wherein the row of objects includes at least two bottles and an elastic connecting member, and the front side wall of one of the at least two bottles is spatially opposite to the rear side wall of the other bottle, and is connected by the elastic connecting member. The vision detection system comprises a bending module and a detection module. The bending module drives the row of objects to bend at least two bottle bodies relative to the elastic connecting piece to form a bending angle. The detection module is spatially opposite to the at least two bottles, and detects the front side wall and the rear side wall of the adjacent elastic connecting piece when the bending module drives the at least two bottles of the continuous object to form a bending angle.

In an embodiment, the row of objects includes a front end, a rear end, a first side and a second side, the front end and the rear end are opposite to each other, the first side and the second side are opposite to each other, and the first side and the second side are connected between the front end and the rear end, wherein when the bending module drives at least two bottles to form a bending angle, the first side and the second side form a convex arc side and a concave arc side respectively, and the detection module faces the convex arc side.

In an embodiment, the bending module is a transmission track and includes at least one convex arc segment, and the detecting module is spatially disposed opposite to the convex arc segment, so that the first side or the second side forms a convex arc side when the front end of the row of objects enters the at least one convex arc segment.

In an embodiment, the bending module is an S-shaped transmission track, and includes two convex arc segments connected in sequence, and when the front end of the row of objects enters the S-shaped transmission track, the first side and the second side form convex arc sides in sequence for the detection module to detect the front side wall and the rear side wall on the row of objects.

In an embodiment, the bending module is a clamping arm, and when clamping the row of objects, bending operation is performed to make the first side or the second side form a convex arc side and face the detection module.

In one embodiment, the gripping arm further comprises an upright operation, a lying operation, a rotating operation, or a vibrating operation.

In one embodiment, the bending angle ranges from 150 degrees to 170 degrees.

In one embodiment, at least two bottles are each composed of a light-transmissive material and are assembled with a liquid.

In one embodiment, the at least two bottles and the elastic connecting member are made of a plastic material and are integrally formed.

In one embodiment, each bottle has a rectangular or square horizontal cross section.

The invention has the beneficial effects that the invention provides a visual detection system for detecting a row of objects. Because the two adjacent bottles of the continuous-row objects are connected by the elastic connecting piece, the visual detection system drives the continuous-row objects through the bending module, so that the two adjacent bottles form a bending angle to expose the side walls of the two bottles, the detection module is used for detecting the side walls, the problem that the two adjacent bottles cannot be detected that the two adjacent bottles are abnormal on the side walls is solved, the requirement of manual visual detection is eliminated, and the detection efficiency is effectively improved.

Fig. 1 is a perspective view of a row of articles according to an embodiment of the present invention. FIG. 2 is a top view of a relationship between a row of objects and a detection module according to an embodiment of the invention. Fig. 3A and 3B illustrate a visual inspection system for inline objects according to a first embodiment of the present invention. Fig. 4A and fig. 4B are schematic diagrams illustrating an example of a visual inspection system for inspecting a row of objects according to a first embodiment of the present invention. In this embodiment, the vision inspection system 2 is configured to inspect a row of objects 1. The row of articles 1 comprises a plurality of bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, wherein every two adjacent bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h are connected through an elastic connecting piece 13 to form an integrated row of articles 1. The bottle bodies 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h and the elastic connecting member 13 are made of, for example, a plastic material, and are integrally formed. In this embodiment, each bottle 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h has a rectangular or square horizontal cross section, and includes a front sidewall 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h and a corresponding rear sidewall 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h. In the present embodiment, the front side wall 11a of the bottle 10a forms, for example, the front end of the row of articles 1, and the rear side wall 12h of the bottle 10h forms, for example, the rear end of the row of articles 1, the front end and the rear end being opposite to each other. Furthermore, the row of articles 1 comprises a first side 14 and a second side 15 opposite to each other. Wherein the first side 14 and the second side 15 are connected between the front end and the rear end. In the present embodiment, the number of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h is eight, but the invention is not limited thereto. In other embodiments, at least two adjacent bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, such as the front sidewall 11b of the bottle 10b, are spatially opposite to the rear sidewall 12a of the other bottle 10a and connected by the elastic connection 13.

In this embodiment, the visual inspection system 2 includes a bending module and an inspection module D. The bending module is, for example, a transmission track 30, and is configured to drive the row of objects 1 to bend, for example, the elastic connecting pieces 13 between the bottle bodies 10a and 10b, so as to form a bending angle θ. In addition, in the present embodiment, the detection module D is, for example, an image capturing device or an image capturing lens, and is spatially located adjacent to at least two of the bottles 10a, 10b, 10c, 10D, 10e, 10f, 10g, and 10h, for example, the bottle 10a and the bottle 10b. When the bending module drives the row of articles 1 to form a bending angle θ between the bottle bodies 10a and 10b, the detecting module D detects the front sidewall 11b and the rear sidewall 12a adjacent to the elastic connecting piece 13.

In this embodiment, the transmission track 30 as the bending module includes at least one convex arc segment, and the detection module D is spatially disposed relative to the convex arc segment, as shown in fig. 3A and 3B. In the present embodiment, when the front end of the row of objects 1 (the front side wall 11a of the bottle 10 a) enters at least one convex arc section, the first side 14 of the row of objects 1 forms a convex arc side facing the detection module D, and the rear side wall 12a of the bottle 10a and the front side wall 11b of the bottle 10b are exposed due to the formed bending angle θ, as shown in fig. 4A. At this time, the detection module D can observe and check the rear side wall 12a of the bottle 10a and the front side wall 11b of the bottle 10b to confirm whether or not flaws exist on the front side wall 11b of the bottle 10b and the rear side wall 12a of the bottle 10a to mark the flaws. In other words, the visual inspection system 2 of the present invention drives the row of objects 1 through the bending module, so that, for example, two adjacent bottles 10a and 10b form a bending angle θ to expose the rear sidewall 12a and the front sidewall 11b, so that the inspection module D can inspect the sidewalls, solve the problem that the defects on the dead angles of the sidewalls cannot be inspected in the prior art, eliminate the requirement of manual visual inspection, and effectively improve the inspection efficiency. It should be noted that, when the bending module drives at least two adjacent rows of articles 1, such as bottles 10a and 10b, to generate the bending angle θ, the first side 14 or the second side 15 may be selected to form a convex arc side for visual detection relative to the detection module D. In one embodiment, the first side 14 and the second side 15 of the row of objects 1 respectively form a convex arc side and a concave arc side, as shown in fig. 4A. In another embodiment, the second side 15 and the first side 14 of the row of objects 1 form a convex arc side and a concave arc side, respectively, as shown in fig. 4B. In other embodiments, the first side 14 or the second side 15 of the row of objects 1 is selected to form a convex arc side for the detection module D to detect with respect to the design of the conveying track 30, which is not limited to the present invention.

In the present embodiment, the transmission track 30 as the bending module can make the bent row of objects 1 sequentially pass through the detecting module D from the bottle 10a to the bottle 10 h. The detection module D can sequentially detect the rear sidewall 12g of the bottle 10g and the front sidewall 11h of the bottle 10h from the rear sidewall 12a of the bottle 10a and the front sidewall 11b of the bottle 10b. Of course, the order of detection is merely illustrative, and does not limit the essential technical features of the present invention. As described herein.

In addition, it should be noted that, in the present embodiment, the bending module drives at least two adjacent rows of the objects 1, for example, the bottles 10a and 10b, to generate a bending angle θ between 150 ° and 170 °, which is helpful for the detection module D to detect, and at the same time, can avoid the elastic connection member 13 from being broken or the bottles 10a and 10b from being separated due to excessive bending.

Fig. 5 is a diagram of a visual inspection system for inline articles in accordance with a second embodiment of the present invention. In the present embodiment, the visual inspection system 2a is similar to the visual inspection system 2 shown in fig. 1 to 4B, and the same reference numerals refer to the same elements, structures and functions, and are not repeated herein. In this embodiment, the bending module of the visual inspection system 2a is, for example, an S-shaped transmission track 30, which includes two convex arc segments sequentially connected to correspond to the inspection module D2 and the inspection module D3, respectively. When the front end (the front side wall 11a of the bottle body 10 a) of the row of objects 1 enters the S-shaped transmission track 30, the first side 14 forms a convex arc side for detection by the detection module D2, and then the second side 15 forms a convex arc for detection by the detection module D3. When the transmission track 30 is designed as S-shaped, the two opposite sides of the row of objects 1, namely the first side 14 and the second side 15, can be visually inspected together by the arrangement of the detection modules D2 and D3, and the first side 14 and the second side 15 can clearly distinguish whether the front side wall 11a, 11b, 11c, 11D, 11e, 11f, 11g, 11h and the rear side wall 12a, 12b, 12c, 12D, 12e, 12f, 12g, 12h are abnormal or not, and the visual inspection system 2a can be integrated together into the automatic production line, thereby improving the inspection efficiency. In the present embodiment, the bottle body 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h is made of a light-transmitting material, and each detection module D2, D3 is provided with a light source S corresponding to the detection module D2, D3 in space. During detection, the light source S irradiates from the concave arc side to the convex arc side of the continuous object 1, is received by the corresponding detection modules D2 and D3, and strengthens the analysis capability of the detection modules D2 and D3. Of course, the invention is not limited thereto. In addition, in the present embodiment, the front and rear sections of the S-shaped transmission track 30 can be matched with the detection module D1 and the detection module D4 again, so as to perform visual detection on the first side 14 and the second side 15 when the row of objects 1 are not bent, further provide visual detection results at different angles, and enhance the capability of the visual detection system 2a to detect anomalies. Of course, the invention is not limited thereto.

Fig. 6A is a diagram illustrating a visual inspection system according to a third embodiment of the present invention. In the present embodiment, the visual inspection system 2B is similar to the visual inspection system 2 shown in fig. 1 to 4B, and the same reference numerals refer to the same elements, structures and functions, and are not repeated herein. In the present embodiment, the bending module of the visual inspection system 2b is implemented by, for example, a clamping arm 30 a. After the gripping arm 30a grips the bottle heads of the bottle bodies 10a, 10b, 10c, 10D, 10e, 10f, 10g and 10h, a bending operation is performed, so that the first side 14 of the row of objects 1 forms a convex arc with the side facing the detection module D. In this embodiment, the detection module D can be displaced relative to the row of objects 1, and sequentially detects from the rear sidewall 12a of the bottle 10a and the front sidewall 11b of the bottle 10b. In other embodiments, the visual inspection system 2b includes a plurality of inspection modules D for inspecting each of the front side walls 11a, 11b, 11c, 11D, 11e, 11f, 11g, 11h and each of the rear side walls 12a, 12b, 12c, 12D, 12e, 12f, 12g, 12h simultaneously with respect to the bent row of articles 1.

Fig. 6B is a diagram illustrating a visual inspection system according to a fourth embodiment of the present invention. In the present embodiment, the visual inspection system 2c is similar to the visual inspection system 2b shown in fig. 6A, and the same reference numerals refer to the same elements, structures and functions, and are not repeated herein. In this embodiment, the bending module of the vision inspection system 2c is also realized by the clamping arm 30a, for example. After the gripping arm 30a grips the bottle heads of the bottles 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h and performs a bending operation, the gripping arm 30a further performs a rotating operation, so that the first side 14 of the row of objects 1 forming the convex arc faces the detection module D and is displaced, and the detection module D is spatially and directly opposite to at least two adjacent ones of the bottles 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h, such as the bottle 10D and the bottle 10e, and detects the front sidewall 11e and the rear sidewall 12D adjacent to the elastic connection member 13. The present invention is not limited to the number and order of detection of the front side walls 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h and the rear side walls 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h. In other embodiments, the gripper arm 30a performs a different type of inspection process after gripping the row of objects 1, thereby enhancing the inspection capability and multiple applications of the vision inspection system 2 c.

FIG. 7 discloses a visual inspection system of the present invention for inspecting the bottom surface of a row of objects. In this embodiment, the row of objects 1 is made of a transparent material, and each bottle 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h (refer to fig. 1 and 2) is filled with a liquid L such as artificial tears, saline or micro-drug, and after the arm 30a clamps the bottle heads of the bottles 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h, it is further combined with a detection module D to observe and check whether the bottle 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h or the liquid L filled therein is abnormal or not.

Fig. 8 discloses a visual inspection system of the present invention for performing level inspection of an inline article. In this embodiment, the gripping arm 30a grips the bottle heads of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, and then performs a lying operation, or places the row of articles 1 on a transparent glass (not shown). Then, a detection module D is used to observe and check each bottle 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h or the liquid L filled therein from the lower side of the row of objects 1 to determine whether an abnormality or flaw exists and mark the abnormality.

Fig. 9A to 9C disclose the visual inspection system of the present invention for upright inspection and post-concussion inspection of a row of objects. In this embodiment, the gripping arm 30a grips the heads of the bottle bodies 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, and then performs a standing test on the first side 14 or the second side 15, as shown in fig. 9A. In another embodiment, as shown in fig. 9B to 9C, after the gripping arm 30a grips the bottle heads of the bottle bodies 10a, 10B, 10C, 10D, 10e, 10f, 10g, and 10h, a shaking operation is further performed, and the shaking operation is repeated 3 to 5 times, so that the foreign matters in the bottle bodies 10a, 10B, 10C, 10D, 10e, 10f, 10g, and 10h can be accurately detected by the detection module D. Of course, the invention is not limited thereto.

Fig. 10A and 10I illustrate a visual inspection system according to a fifth embodiment of the present invention. In the present embodiment, the visual inspection system 2d is similar to the visual inspection system 2b shown in fig. 6A, and the same reference numerals refer to the same elements, structures and functions, and are not repeated herein. In the present embodiment, the bending module of the vision inspection system 2d is implemented by, for example, the gripping arm 30b of the robot arm device 3, and the vision inspection system 2d further integrates multiple vision inspection functions through the programming of the robot arm device 3. In this embodiment, the row of objects 1 is conveyed on a linear conveying track 301, and the detection module D1 can perform vertical detection on the second side 15 of the row of objects 1 by corresponding arrangement of the detection module D1, for example, shooting the bottle heads of the bottles 10A, 10b, 10c, 10D, 10e, 10f, 10g, 10h (refer to fig. 1 and 2), as shown in fig. 10A.

The present invention is not limited to the order of the operations of gripping the arm 30 b. In an embodiment, as shown in fig. 10C, after the gripping arm 30b grips the row of objects 1, the automated arm device 3 rotates, and moves the row of objects 1 above a detection module D2, and the detection module D2 detects the bottom surface of the row of objects 1 in a direction from bottom to top by the corresponding arrangement of the detection module D2 (refer to fig. 7), so as to confirm whether there is an abnormality or a flaw in the bottle 10a to the bottle 10h, and mark the abnormality. In one embodiment, as shown in fig. 10D, after the gripping arm 30b grips the row of objects 1, the automatic arm device 3 rotates, and performs a lying operation to lie the row of objects 1 above a detection module D3, and the detection module D3 performs a lying detection of the row of objects 1 in a direction from bottom to top through the corresponding arrangement of the detection module D3 (refer to fig. 8), so as to confirm whether there is an abnormality or a flaw in the bottle 10a to the bottle 10h and mark the abnormality. In one embodiment, as shown in fig. 10D, after the gripping arm 30B grips the row of objects 1, the automatic arm device 3 rotates, and performs a bending operation to form a convex arc side on the first side 14 of the row of objects 1, and the detection module D4 and the detection module D5 perform a sidewall detection on the row of objects 1 with respect to the direction of the first side 14 of the row of objects 1 through the corresponding arrangement of the detection module D4 and the detection module D5 (refer to fig. 6B), so as to confirm whether an abnormality or a flaw exists in the bottle body 10a to the bottle body 10h and mark the abnormality. The gripping arm 30b may rotate the row of objects 1 sequentially about the center of the convex arc formed on the first side 14, so that the detection module D4 and the detection module D5 can sequentially detect whether the side wall of the bottle 10a, 10b, 10c, 10D, 10e, 10f, 10g, 10h has an abnormality or a defect to mark the abnormality. In an embodiment, after the detection module D4 and the detection module D5 sequentially complete the detection of the sidewalls of the bottles 10a, 10b, 10c, 10D, 10e, 10F, 10g, 10h from the first side 14, the gripper arm 30b may rotate the row of objects 1 180 degrees, for example, with the center of the circle on the convex arc side formed by the first side 14 as the center, as shown in fig. 10F. Then, the first side 14, which is the convex arc side, is reversely folded to be the concave arc side, so that the second side 15 of the row of objects 1 is the convex arc side. At this time, by the corresponding arrangement of the detection modules D6 and D7, the detection modules D6 and D6 detect the side walls of the row of articles 1 with respect to the second side 15 direction of the row of articles 1, and confirm whether the bottle 10a to 10h are abnormal or have flaws to mark the bottle. In this embodiment, for the row of objects 1 for which the sidewall inspection is completed, the robot 3 may rotate the gripper arm 30b to allow the gripper arm 30b to place the row of objects 1 on another linear transport rail 302 for transport, as shown in fig. 10H, so that the row of objects 1 may be transported on the linear transport rail 302. In an embodiment, by the corresponding arrangement of the detection modules D8 and D9, the detection modules D8 and D9 can detect the vibration of the second side 15 of the row of objects 1 after the vibration, for example, the vibration shooting 3 to 5 times in cooperation with the other rotary vibration device 3 a. In other embodiments, the detection of the row 1 after the oscillation can be performed by, for example, pinching the arm 30B (see fig. 9B and 9C). Of course, the present invention is not limited to the operation timing of the robotic arm device 3 for manipulating the gripper arm 30, and will not be described again.

It should be noted that, in the foregoing embodiment, the bending module of the vision inspection system 2d is implemented by, for example, the gripping arm 30b of the robot arm device 3, and the vision inspection system 2d is integrated into a vision inspection workstation in a limited space. The gripping arm 30b is used to grip the row of articles 1, and in the revolving operation range, bending operation, standing operation, lying operation, rotating operation or oscillating operation is performed, so that the row of articles 1 can be driven to face the detection modules D2-D9 at a convex arc side, and the omnibearing visual detection of the bottle bodies 10a, 10b, 10c, 10D, 10e, 10f, 10g and 10h is realized. In addition, the clamping arm 30b can further rotate the clamping row of objects 1 horizontally by 180 degrees and then bend reversely, so as to complete visual detection of two opposite sides of the row of objects 1 by matching with the detection modules D4-D7. Of course, the visual inspection system 2d is only illustrative and the invention is not limited thereto, and other inspection sequences such as bottom, horizontal, vertical and post-shake inspection are also incorporated. In an embodiment, the gripping arm 30b of the automated arm device 3 is further combined with the conveying track 30, so as to realize the overall automated detection of the row of objects 1, and reduce the occurrence of defects that are not detected and affect the product yield. In other embodiments, the direction, sequence and means of bending the row of objects 1 by the bending module can be modulated according to the actual application requirements. The present invention is not limited thereto, and will not be described in detail.

In summary, the present invention provides a visual inspection system for inspecting a row of objects. Because the two adjacent bottles of the continuous-row objects are connected by the elastic connecting piece, the visual detection system drives the continuous-row objects through the bending module, so that the two adjacent bottles form a bending angle to expose the side walls of the two bottles, the detection module is used for detecting the side walls, the problem that the two adjacent bottles cannot be detected that the two adjacent bottles are abnormal on the side walls is solved, the requirement of manual visual detection is eliminated, and the detection efficiency is effectively improved. Furthermore, the bending module drives the connecting objects to limit the bending angle formed by two adjacent bottles to 150-170 degrees, which is helpful for the detection module to detect and can avoid the elastic connecting piece from breaking or separating the bottles due to excessive bending. The driving of the row of objects enables two adjacent bottle bodies to form a bending module with a bending angle, which can be realized through a transmission track. The design of the transmission track can drive the continuous objects to form convex arc sides to be opposite to the detection module during transmission, so that visual detection of the side wall between two adjacent bottles is realized. In addition, when the transmission track is designed into an S-shaped transmission track, the visual detection of two opposite sides of the objects in the row can be completed together by arranging the detection modules. In addition, the driving of the row of objects to form the bending modules with the bending angles between the two adjacent bottle bodies can be realized by, for example, automatic mechanical clamping arms. The arm is clamped to clamp the continuous objects, and bending operation, standing operation, lying operation, rotating operation or oscillating operation is carried out, so that the continuous objects can be driven to face the detection module at the convex arc side, and visual detection of the side wall between two adjacent bottle bodies is realized. The clamping arm can further clamp the objects in the row to rotate 180 degrees horizontally and then bend reversely, and the visual detection of the two opposite sides of the objects in the row can be completed by matching with the detection module. On the other hand, the visual detection system can integrate other detection items such as the bottom surface, the horizontal surface, the vertical surface and the vibration post, so that the comprehensive automatic detection of the continuous objects is realized, and the defect that the defect is not detected and the product yield is prevented from being influenced. The method has industrial applicability.

The present invention is modified in a manner that would be apparent to one skilled in the art without departing from the scope of the invention as set forth in the appended claims.
