Description

Visual inspection system for row objects

This case is about a visual inspection system, especially a visual inspection system for serial objects, which is used to solve the problem of undetectable side wall defects in serial objects and at the same time improve the detection efficiency of the visual inspection system.

Generally speaking, liquids such as artificial tears, physiological saline or trace pharmaceuticals are often packaged in rows, taking into account the single use volume and convenience of storage. The plurality of bottles are, for example, made of translucent plastic material. Each bottle contains a trace amount of liquid solution, and the bottles are connected to each other to form a row of packaging. However, when these products are filled with liquid solutions, abnormalities such as foreign matter in the bottle, abnormal liquid volume, or discoloration of the solution may occur. Therefore, abnormality detection must be carried out manually or with the assistance of visual inspection instruments. In addition, the same applies to defects on the outside of the bottle, such as black spots on the outer bottle, white spots on the bottle cap, burrs on the bottle body, or water leakage from the twisted cap.

Although, the assistance of visual inspection equipment can help increase the speed of inspection. However, when traditional visual inspection instruments perform anomaly detection, image sampling analysis is used. For some areas of connected objects, such as where two adjacent bottles are in close contact, effective image sampling analysis cannot be performed. In other words, when defects exist in the blind spots of image sampling, traditional visual inspection instruments cannot detect them, or may cause misjudgments. Finally, manual assistance is still needed to solve the problem, which is time-consuming and labor-intensive.

In view of this, it is necessary to provide a visual inspection system for continuous objects. The bending module operates the corresponding angle of the continuous objects relative to the inspection module to effectively detect defects on the side walls of the continuous objects and further improve visual inspection. System detection performance to solve the deficiencies in conventional technology.

The purpose of this project is to provide a visual inspection system to detect a row of objects. Since the two adjacent bottles of the serial object are connected by elastic connectors, the visual inspection system in this case drives the serial object through the bending module, so that the two adjacent bottles form a bending angle to expose the gap between the two bottles. The side wall is used to facilitate the detection module to perform side wall detection, solving the problem of being unable to detect abnormalities on the side wall between two adjacent bottles, eliminating the need for manual visual inspection, and effectively improving detection efficiency. Furthermore, when the bending module drives the connected objects to form a bending angle between two adjacent bottles between 150 degrees and 170 degrees, it not only helps the detection module to detect, but also avoids excessive bending. The elastic connector is broken or the bottle body is separated.

Another purpose of this project is to provide a visual inspection system for inspecting a row of objects. The bending module that drives the connected objects to form a bending angle between two adjacent bottles can be implemented, for example, through a transmission track. Among them, through the transmission track design, the continuous objects can be driven to form a convex arc side and face the detection module during transportation, thereby achieving visual inspection of the side walls between two adjacent bottles. In addition, when the transmission track is designed as an S-shaped transmission track, visual inspection of two opposite sides of the row of objects can be completed together with the setting of the detection module.

Another purpose of this project is to provide a visual inspection system for inspecting a row of objects. The bending module that drives the connected objects to form a bending angle between two adjacent bottles can be realized, for example, through an automated mechanical gripping arm. Among them, by using the clamping arm to pick up the serial objects and perform bending, upright, lying, rotating or shaking operations, the serial objects can be driven to face the detection module on a convex arc side to achieve two-phase Visual inspection of side walls between adjacent bottles. The gripping arm can further rotate the gripped serial objects 180 degrees horizontally and then bend them in the opposite direction. It can be used with the inspection module to complete visual inspection of the two opposite sides of the serial objects. On the other hand, the visual inspection system can integrate other inspection items such as bottom, horizontal, vertical and post-shock inspections to achieve comprehensive automated inspection of serial objects to avoid undetected defects that affect product yield.

In order to achieve the aforementioned purpose, this case provides a visual inspection system for detecting a row of objects, wherein the row of objects includes at least two bottles and an elastic connector, and the front side wall of at least one of the two bottles is spatially relative to The rear side wall of the other is connected through an elastic connector. The visual inspection system includes a bending module and an inspection module. The bending module drives the connected objects to bend at least two bottles relative to the elastic connector to form a bending angle. The detection module is spatially relative to at least two bottles, and when a bending angle is formed between at least two bottles of the connected object driven by the bending module, the detection module detects the front side wall and the rear side wall of the adjacent elastic connector.

In one embodiment, the connected object 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 to Between the front end and the rear end, when the bending module drives at least two bottles to form a bending angle, the first side and the second side respectively form a convex arc side and a concave arc side, and the detection module faces the convex arc. side.

In one embodiment, the bending module is a transmission track that includes at least one convex arc segment. The detection module is spatially disposed relative to the convex arc segment. When the front end of the row of objects enters the at least one convex arc segment, the detection module is The first side or the second side forms a convex arc side.

In one embodiment, the bending module is an S-shaped transmission track, including two convex arc segments connected in sequence. When the front end of the row of objects enters the S-shaped transmission track, the first side and the second side form convex sections in sequence. The arc side is used for the detection module to detect the front side wall and rear side wall of the continuous objects.

In one embodiment, the bending module is a clamping arm. When clamping consecutive objects, the bending operation is performed so that the first side or the second side forms a convex arc side and faces the detection module.

In one embodiment, the gripping arm further includes an upright operation, a lying operation, a rotation operation or a shock operation.

Figure 2 is a top view showing the relationship between the connected objects and the relative detection modules according to the embodiment of the present invention. Figures 3A and 3B illustrate the visual inspection system for serial objects according to the first embodiment of the present invention. Figures 4A and 4B illustrate an example of the visual inspection system of the first embodiment of the present invention performing continuous object inspection. In this embodiment, the visual inspection system 2 is configured to measure a row of objects 1 . The row object 1 includes a plurality of bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h. Each two adjacent bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h pass through an elastic The connectors 13 are connected to form an integrated serial object 1 . The bottle body 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h and the elastic connecting member 13 are all made of a plastic material, for example, and are integrally formed. In this embodiment, the horizontal cross-section of each bottle 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h is in the shape of a rectangle or a square, and includes front side walls 11a, 11b, 11c, 11d, 11e, respectively. 11f, 11g, 11h and the corresponding rear side walls 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h. In this embodiment, the front side wall 11a of the bottle body 10a constitutes the front end of the serial object 1, for example, and the rear side wall 12h of the bottle body 10h constitutes the rear end of the serial object 1, for example. The front end and the rear end are opposite to each other. Furthermore, the connected object 1 includes a first side 14 and a second side 15 opposite to each other. The first side 14 and the second side 15 are connected between the front end and the rear end. It should be noted that in this embodiment, the number of bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h is eight, but the case is not limited to this. In other embodiments, at least two adjacent ones of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h, such as the front side wall 11b of the bottle 10b, are spatially relative to the rear side wall of the other bottle 10a. 12a, and connected through elastic connector 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, which is assembled to drive the connected object 1 to bend, for example, the bottle body 10a and the bottle body 10b relative to the elastic connecting member 13 therebetween to form a bending angle θ. In addition, in this embodiment, the detection module D is, for example, an image capture device or a camera lens, and is spatially relative to at least two adjacent ones of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h. , such as bottle body 10a and bottle body 10b. When the bending module drives the connected object 1 to form a bending angle θ between the bottles 10a and 10b, the detection module D detects the front side wall 11b and the rear side wall 12a adjacent to the elastic connector 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 Figures 3A and 3B. In this embodiment, when the front end of the row of objects 1 (the front side wall 11a of the bottle body 10a) 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 , the rear side wall 12a of the bottle body 10a and the front side wall 11b of the bottle body 10b are exposed due to the bending angle θ formed, as shown in Figure 4A. At this time, the detection module D can observe and inspect the rear side wall 12a of the bottle 10a and the front side wall 11b of the bottle 10b to confirm whether there are any defects on the front side wall 11b of the bottle 10b and the rear side wall 12a of the bottle 10a. Mark an exception if it exists. In other words, the visual inspection system 2 in this case drives the serial object 1 through the bending module, so that, for example, two adjacent bottles 10a and 10b form a bending angle θ to expose the rear side wall 12a and the front side wall 11b, so as to facilitate the detection of the mold. Group D conducts side wall inspection to solve the conventional problem of being unable to detect abnormalities in the dead corners of the side wall, eliminating the need for manual visual inspection and effectively improving inspection efficiency. It should be noted that when the bending module drives at least two adjacent connected objects 1, such as the bottle body 10a and the bottle body 10b, to produce a bending angle θ, the first side 14 or the second side 15 can be selected to form a convex arc side. Use relative detection module D for visual inspection. In one embodiment, the first side 14 and the second side 15 of the connected object 1 form a convex arc side and a concave arc side respectively, as shown in Figure 4A. In another embodiment, the second side 15 and the first side 14 of the connected object 1 form a convex arc side and a concave arc side respectively, as shown in Figure 4B. In other embodiments, the serial object 1 selects the first side 14 or the second side 15 to form a convex arc side relative to the design of the transmission track 30 for detection by the detection module D. This case is not limited to this.

In this embodiment, the transmission track 30 as a bending module can allow the bent objects 1 to pass through the detection module D sequentially from the bottle 10a to the bottle 10h. The detection module D can sequentially detect the rear side wall 12g of the bottle body 10a and the front side wall 11b of the bottle body 10b to the rear side wall 12g of the bottle body 10g and the front side wall 11h of the bottle body 10h. Of course, the order of testing is only an example and does not limit the necessary technical features of this case. Let’s explain this first.

In addition, it is worth noting that in this embodiment, the bending module drives the bending angle θ of at least two adjacent objects 1, such as the bottle 10a and the bottle 10b, to be between 150 degrees and 170 degrees. , in addition to being helpful for detection by the detection module D, it can also avoid excessive bending to cause the elastic connector 13 to break or the bottle body 10a to separate from the bottle body 10b.

Figure 5 shows the visual inspection system for continuous objects in the second embodiment of the present invention. In this embodiment, the visual inspection system 2a is similar to the visual inspection system 2 shown in Figures 1 to 4B, and the same component numbers represent the same components, structures and functions, which will not be described again. 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 connected in sequence, corresponding to the inspection module D2 and the inspection module D3 respectively. When the front end of the row of objects 1 (the front side wall 11a of the bottle body 10a) enters the S-shaped transmission track 30, the first side 14 first 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 detection module D3. When the transmission track 30 is designed to be S-shaped, with the setting of the detection modules D2 and D3, the visual inspection of the two opposite sides of the row object 1, that is, the first side 14 and the second side 15, can be completed at the same time. 14 and the second side 15 to clearly identify whether each front side wall 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h and each rear side wall 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h has Abnormalities exist, and it helps to integrate the visual inspection system 2a into the automated production line to improve inspection efficiency. In this embodiment, the bottle body 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h is made of a light-transmitting material, for example, and each detection module D2, D3 is provided with a light source S, for example, in space. Relative to detection modules D2 and D3. During detection, the light source S is emitted from the concave arc side of the serial object 1 and from the convex arc side, and is received by the corresponding detection modules D2 and D3, thereby enhancing the analytical capabilities of the detection modules D2 and D3. Of course, this case is not limited to this. In addition, in this embodiment, the front and rear sections of the S-shaped transmission track 30 can further cooperate with the detection module D1 and the detection module D4 to perform visual inspection of the first side 14 and the second side 15 when the row of objects 1 is not bent. Detection further provides comparison of visual detection results from different angles, strengthening the ability of the visual detection system 2a to detect abnormalities. Of course, this case is not limited to this.

In this embodiment, the bending module of the visual inspection system 2b is implemented by, for example, the clamping arm 30a. For example, the clamping arm 30a clamps the bottle heads of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h, and then performs a bending operation to form a convex arc side surface on the first side 14 of the serial object 1 To the detection module D. In this embodiment, the detection module D can, for example, be displaced relative to the serial object 1 and detect sequentially starting from the rear side wall 12a of the bottle body 10a and the front side wall 11b of the bottle body 10b. In other embodiments, the visual inspection system 2b includes, for example, a plurality of inspection modules D, which are used to simultaneously detect each of the front side walls 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h is visually inspected with each rear side wall 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h.

In this embodiment, the bending module of the visual inspection system 2c is also implemented by, for example, the clamping arm 30a. 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 rotation operation to form a row of objects 1. The first side 14 of the convex arc side faces the detection module D and generates a displacement so that the detection module D is directly spatially relative to at least two adjacent ones of the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h. For example, the bottle body 10d and the bottle body 10e are detected, and the front side wall 11e and the rear side wall 12d adjacent to the elastic connector 13 are detected. This case 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 gripping arm 30a grips the serial objects 1 and then performs different types of inspection processes, thereby enhancing the inspection capabilities and diversified applications of the visual inspection system 2c.

Figure 7 shows that the visual inspection system in this case performs bottom surface inspection of continuous objects.

The operation is repeated 3 to 5 times, so that the foreign matter existing in the bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g and 10h can be accurately detected by the detection module D. Of course, this case is not limited to this.

In other embodiments, the post-shock detection of the serial object 1 can also be accomplished by, for example, the gripper arm 30b (refer to Figures 9B and 9C). Of course, this case is not limited to the operation sequence of the automatic arm device 3 controlling the gripping arm 30, and will not be described again.

It should be noted that, as can be seen from the foregoing embodiments, when the bending module of the visual inspection system 2d is implemented by, for example, the clamping arm 30b of the automated arm device 3, the visual inspection system 2d is further integrated into a visual inspection workstation in a limited space. Among them, the serial objects 1 are clamped by the clamping arm 30b, and within the operating range of its revolution, the serial objects 1 can be driven to move in a direction by performing bending, upright, lying, rotating, or vibrating operations. The convex arc side faces the detection modules D2~D9 to realize all-round visual inspection of bottles 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h. In addition, within the working range of the rotation of the gripping arm 30b, the gripped serial object 1 can be further rotated 180 degrees horizontally and then bent in the opposite direction. The detection modules D4~D7 can be used to complete the detection of the two opposite sides of the serial object 1. Visual inspection. Of course, the order in which the visual inspection system 2d integrates other inspection items such as bottom, horizontal, upright, and post-shock inspection is only an example, and this case is not limited to this. In one embodiment, the clamping arm 30b of the automated arm device 3 is further combined with the aforementioned transmission track 30 to realize comprehensive automated inspection of the serial objects 1 and reduce the occurrence of undetected defects that affect the product yield. In other embodiments, the direction, sequence and method of bending the continuous object 1 by the bending module can be adjusted according to actual application requirements. This case is not limited to this and will not be described again.

To sum up, this project provides a visual inspection system to detect a row of objects. Since the two adjacent bottles of the serial object are connected by elastic connectors, the visual inspection system in this case drives the serial object through the bending module, so that the two adjacent bottles form a bending angle to expose the gap between the two bottles. The side wall is used to facilitate the detection module to perform side wall detection, solving the problem of being unable to detect abnormalities on the side wall between two adjacent bottles, eliminating the need for manual visual inspection, and effectively improving detection efficiency. Furthermore, the bending module drives the connected objects to limit the bending angle formed by two adjacent bottles to between 150 degrees and 170 degrees. This not only helps the detection module to perform inspection, but also avoids excessive bending. Cause the elastic connector to break or the bottle to separate. The bending module in which the connected objects are driven to form a bending angle between two adjacent bottles can be realized, for example, through a transmission track. Among them, through the design of the transmission track, the continuous objects can be driven to form a convex arc side and face the detection module during transportation, thereby achieving visual inspection of the side walls between two adjacent bottles. In addition, when the transmission track is designed as an S-shaped transmission track, visual inspection of two opposite sides of the row of objects can be completed together with the setting of the detection module. In addition, the bending module that drives the connected objects to form a bending angle between two adjacent bottles can be implemented, for example, by an automated mechanical gripping arm. Among them, by using the clamping arm to pick up the serial objects and perform bending, upright, lying, rotating or shaking operations, the serial objects can be driven to face the detection module on a convex arc side to achieve two-phase Visual inspection of side walls between adjacent bottles. The gripping arm can further rotate the gripped serial objects 180 degrees horizontally and then bend them in the opposite direction. It can be used with the inspection module to complete visual inspection of the two opposite sides of the serial objects. On the other hand, the visual inspection system can integrate other inspection items such as bottom, horizontal, vertical and post-shock inspections to achieve comprehensive automated inspection of serial objects to avoid undetected defects that affect product yield. It has real industrial applicability.

This case may be modified in various ways by those who are familiar with this technology, but none of them will deviate from the intended protection within the scope of the patent application.
