Description

Technical Field

[0001] The present invention relates to the technical field of visual inspection, in particular to a multi-station high-precision appearance visual inspection device and an inspection method for an intelligent bottle making machine. Background Art

[0002] A bottle making machine is a device specifically used to manufacture various bottles. It processes raw materials such as glass and plastic through a series of processing steps, such as heating, forming, and cooling, to produce bottles with specific shapes, sizes, and quality requirements.

[0003] After the bottle is produced, it is usually necessary to perform visual inspection on the bottle shape to accurately measure key dimensional parameters such as the bottle diameter, height, bottle mouth diameter, bottle bottom diameter, and whether there are defects such as scratches and cracks on the bottle surface to ensure that it meets production standards and design requirements.

[0004] Existing visual inspection usually uses high-definition cameras to capture images and compare the collected data with the data of qualified products in the image library. In order to ensure that the bottle body can be fully inspected, it is usually necessary to control the bottle body to flip to cooperate with the visual detector for inspection.

[0005] However, the existing clamping and flipping method usually performs the flipping action directly after clamping the bottle body, which may cause the bottle body to not be separated from the conveyor belt, causing interference and causing deformation of the bottle body. In addition, the clamped part of the bottle body cannot be detected, resulting in incomplete detection results. Summary of the Invention

In summary, by controlling the displacement of the card plate, the bottle body is lifted to a certain height before inspection to prevent the problem of deformation of the bottle body due to external force caused by interference with the conveyor belt when the bottle body rotates. At the same time, by controlling the rotation of the bottle body, the bottle mouth and the bottle bottom of the bottle body can be controlled to rotate to a position cooperating with the visual detector, thereby realizing the effect of multi-direction and multi-angle inspection of the bottle body.

[0032] When the clamping plate clamps the outer wall of the bottle and rotates, the opening and bottom of the bottle and the surrounding parts that are not clamped are visually inspected. Since the clamping plate blocks the inspection of a part of the bottle, the inner support plate is used to clamp the inner wall of the bottle and drive the bottle to rotate, so that the outside of the bottle can be fully inspected. With the dual cooperation of the clamping plate and the inner support plate, the accuracy and comprehensiveness of the bottle inspection are ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] See also Figures 1 to 10 In an embodiment of the present invention, a multi-station high-precision appearance visual inspection device for an intelligent bottle making machine includes:

[0047] A conveying platform 1, and pulleys rotatably mounted on the conveying platform 1 and symmetrically arranged, a conveyor belt 3 is sleeved on the pulleys, and a visual detector 4 and a receiving platform 5 are provided on the conveying platform 1;

[0048] Also includes:

[0049] A rotating mechanism is provided on the receiving platform 5, wherein the rotating mechanism is provided with an outer diameter clamping assembly, and the outer diameter clamping assembly is connected to a symmetrically arranged clamping plate 33;

[0050] A spacing adjustment mechanism is provided on the receiving platform 5 and connected to the rotating mechanism. The spacing adjustment mechanism can drive the outer diameter clamping assembly to move through the rotating mechanism to adjust the spacing between the two clamping plates 33;

[0051] The inner diameter clamping mechanism is arranged on the receiving platform 5. The inner diameter clamping mechanism is connected to the inner support plates 15 which are symmetrically arranged. The inner diameter clamping mechanism can drive the two inner support plates 15 to move toward or away from each other.

[0052] Specifically, a reduction motor 2 is provided on the conveyor platform 1 for driving the pulley to rotate. When the bottle body is produced, it can be transferred to the conveyor belt 3. The reduction motor 2 will control the rotation of the pulley to control the bottle body to move to the position of matching with the card plate 33 through the conveyor belt 3. At this time, under the action of the spacing control mechanism, the card plate 33 is controlled to move toward the bottle body through the rotation mechanism and the outer diameter clamping component, and the distance between the two card plates 33 is reduced. When the card plate 33 abuts against the outer wall of the bottle body, the outer diameter clamping component can also control the bottle body to be lifted to a certain height through the card plate 33 to ensure that the bottle body does not interfere with the conveyor belt 3 when rotating. Under the action of the rotation mechanism, The rotation of the bottle body is controlled by the outer diameter clamping assembly and the card plate 33, and the bottle body is inspected from multiple angles under the action of the visual detector 4. When the inspection is completed, the control card plate 33 is reset. At the same time, under the action of the inner diameter clamping mechanism, the inner support plate 15 is inserted into the bottle body while controlling the inner support plate 15 to move away from each other until the inner support plate 15 abuts against the inner wall of the bottle. At this time, the inner diameter clamping mechanism will control the rotation of the bottle body through the inner support plate 15, so as to fully inspect the circumferential outer wall of the bottle body through the visual detector 4. By clamping and turning the bottle body at multiple stations, the effect of multi-angle and all-round inspection of the bottle body is achieved.

[0053] See also Figures 1-6 、 Figure 8 、 Figure 9 The rotating mechanism includes a second motor 17 installed on the receiving platform 5, and a second rotating rod 18 connected to the output shaft of the second motor 17 is rotatably installed on the receiving platform 5. A second sliding sleeve 23 is slidably installed on the second rotating rod 18, and a guide assembly is provided on the second sliding sleeve 23, wherein the guide assembly includes a second support plate 24 installed on the second sliding sleeve 23, and a second sliding groove 2401 is symmetrically arranged on the second support plate 24. A guide column 29 is provided in the second sliding groove 2401, and a second sliding block 26 slidably connected to the second sliding groove 2401 is slidably installed on the guide column 29, and the side wall of the second sliding block 26 is provided with an inclined groove 2601.

[0054] The outer diameter clamping assembly includes a hollow rod 30 installed on the second sliding block 26, a limiting ring 3001 is provided at the end of the hollow rod 30, a movable block 31 is slidably installed on the hollow rod 30 and cooperates with the limiting ring 3001, the movable block 31 is slidably connected to the clamping plate 33, and a third spring 32 is sleeved on the hollow rod 30, and the two ends of the third spring 32 are respectively in contact with the movable block 31 and the second sliding block 26; it also includes a limiting column 34 installed on the clamping plate 33 and slidably connected to the inclined groove 2601.

[0055] Specifically, the visual detector 4 is used to perform visual inspection on bottles. It consists of a high-resolution industrial camera and an adapted optical lens. It uses professional image processing software to grayscale, filter, binarize, and perform edge detection on the captured images. It then analyzes the bottle's shape parameters and features based on preset algorithms and models, such as calculating dimensions like diameter, height, and wall thickness, and identifying defects like scratches, cracks, and bubbles.

[0056] See also Figure 6 , the rotating mechanism is symmetrically provided with two groups, so that the card plates 33 are also provided with two groups, and each group of card plates 33 is composed of two symmetrically arranged card plates 33. The end of the second rotating rod 18 is provided with a second fixing ring 1801 that contacts and cooperates with the second sliding sleeve 23. In the initial state, under the action of the spacing adjustment mechanism, the second support plate 24 is located at the end of the stroke toward the second motor 17, and the distance between the two second sliding blocks 26 is maximized. The third spring 32 is also in a compressed state, so that the movable block 31 is located at the end of the stroke away from the second sliding block 26 and is in abutment with the limiting ring 3001, so that the limiting column 34 is located at the end of the stroke on the side of the inclined groove 2601, so that the distance between the two card plates 33 is maximized and the distance between the conveyor belt 3 is minimized;

[0057] When the bottle needs to be inspected, the spacing control mechanism pushes the second support plate 24 and the second sliding sleeve 23 to move along the length direction of the second rotating rod 18, thereby driving the second sliding block 26 to move, so as to control the clamping plate 33 to move toward the bottle body. When the two symmetrically arranged clamping plates 33 abut against each other, the bottle body is located between the two clamping plates 33. At this time, the spacing control mechanism continues to move and controls the two second sliding blocks 26 to move in the direction of approaching each other. Under the action of the third spring 32, the movable block 31 is pushed to move synchronously to reduce the distance between the two clamping plates 33. When both sets of clamping plates 33 abut against the inner wall of the bottle, the clamping plate 33 and the movable block 31 stop moving, and the second sliding block 26 continues to move and compresses the third spring 32. Under the action of the inclined groove 2601 and the limiting column 34, the clamping plate 33 is moved in the direction away from the conveyor belt 3 to lift the bottle body to a certain height, ensuring that the bottle body does not interfere with the conveyor belt 3 when it rotates.

[0058] Subsequently, the second motor 17 works and drives the second rotating rod 18 to rotate, thereby driving the second supporting plate 24 to rotate through the second sliding sleeve 23. Under the action of the card plate 33, the bottle body is driven to rotate around the second rotating rod 18. Under the action of the visual detector 4, the appearance and size of the circumferential side, bottle port and bottle bottom of the bottle body are inspected and processed. When the bottle body rotates one circle, it means that the inspection is completed. If there are defects in the appearance and size, the visual detector 4 can sound an alarm and record the bad data. At the same time, the unqualified products can be taken out. If the appearance and size are in a qualified state, it is necessary to inspect the circumferential outer wall of the bottle body. Under the action of the spacing control mechanism, the card plate 33 is reset, and the bottle body falls on the conveyor belt 3 again for subsequent inspection.

[0059] Preferably, by controlling the displacement of the card plate 33, the bottle body is lifted to a certain height before detection to prevent the bottle body from being damaged by external force due to interference with the conveyor belt 3 when the bottle body rotates. At the same time, by controlling the rotation of the bottle body, the bottle mouth and the bottle bottom of the bottle body can be controlled to rotate to a position that cooperates with the visual detector 4, thereby achieving the effect of multi-directional and multi-angle detection of the bottle body.

[0060] See also Figures 1-6 、 Figure 9 The spacing adjustment mechanism includes a second movable sleeve 21 slidably mounted on the second rotating rod 18, a second cylinder 19 is provided on the receiving platform 5, and a second movable plate 20 rotatably connected to the second movable sleeve 21 is provided on the telescopic end of the second cylinder 19, and a driven assembly connected to the second sliding block 26 is provided on the second movable sleeve 21, wherein the driven assembly includes a rotating plate 22 mounted on the second movable sleeve 21, and a second spring 25 is sleeved on the second rotating rod 18, and the two ends of the second spring 25 are respectively in contact with the rotating plate 22 and the second support plate 24, and a symmetrically arranged support sleeve 27 is provided on the rotating plate 22, and a support rod 28 fixedly connected to the second sliding block 26 is slidably installed in the support sleeve 27.

[0061] It should be noted that, in the initial state, under the action of the second cylinder 19, the second movable plate 20 is located at the end of the stroke toward the second motor 17, so that the distance between the rotating plate 22 and the second motor 17 is minimized by controlling the second movable sleeve 21, and the second rotating rod 18, the second support plate 24, the support sleeve 27 and the support rod 28 are combined to form a right-angled triangle. Since the second spring 25 is in a compressed state, the second support plate 24 is located at the end of the stroke away from the rotating plate 22. Therefore, one of the right-angled sides represented by the second rotating rod 18 has the largest length, so that the second sliding block 26 is located at the end of the stroke in the second slide groove 2401 away from the second rotating rod 18, so that the size of the mutual fit between the support sleeve 27 and the support rod 28 is minimized. When it is necessary to control the clamping plate 33 to clamp the bottle body, the second cylinder 25 is in a compressed state. 19 works and pushes the second movable plate 20 to move, thereby driving the rotating plate 22 to move synchronously through the second movable sleeve 21. Under the action of the second spring 25, the second support plate 24 moves synchronously, so that the distance between the two sets of card plates 33 gradually decreases. When the two card plates 33 abut against each other, the position of the second support plate 24 no longer changes. At this time, the rotating plate 22 continues to move toward the second support plate 24 and compresses the second spring 25. At the same time, the size of the mutual fit between the support sleeve 27 and the support rod 28 increases, so that the length of the oblique angle in the triangle decreases, so as to control the second sliding block 26 to slide along the length direction of the second slide groove 2401 and move toward the direction of the second rotating rod 18, thereby reducing the distance between the two card plates 33. Until the card plate 33 fixes the bottle body and lifts it to a certain height, the second cylinder 19 stops moving.

[0062] Preferably, the elastic thrust provided to the second support plate 24 by the second spring 25 can be achieved when the two sets of card plates 33 abut against each other, so as to adjust the distance between the two card plates 33, thereby achieving the effect of first driving the card plates 33 to move in the horizontal direction and then adjusting the distance between the card plates 33. Among them, since the qualified size of the bottle body to be measured is fixed, the distance between the two card plates 33 approaching each other is certain, and an infrared sensor can be installed on the card plate 33. If the bottle body size is large, it means that when the card plate 33 abuts against the bottle body, the infrared sensor can measure the distance between the two card plates 33 greater than the set value. If the bottle body size is small, it means that when the card plate 33 abuts against the bottle body, the infrared sensor can measure the distance between the two card plates 33 less than the set value. By comparing the required measurement value with the set value, it is possible to further detect whether the bottle body size is qualified. The infrared sensor is an application of the existing technology and is not described in detail in this application.

[0063] See also Figures 1-4 、 Figure 7 、 Figure 10The inner diameter clamping mechanism includes a first motor 6 installed on the receiving platform 5, a first rotating rod 7 connected to the output shaft of the first motor 6 is rotatably installed on the receiving platform 5, a first sliding sleeve 11 is slidably installed on the first rotating rod 7, and a sliding assembly is provided on the first sliding sleeve 11, wherein the sliding assembly includes a first support plate 12 installed on the first sliding sleeve 11, a first sliding groove 1201 is symmetrically arranged on the first support plate 12, a first sliding block 14 is slidably installed in the first sliding groove 1201, and the first sliding block 14 is fixed to the inner support plate 15 The supporting platform 5 is provided with a follow-up structure connected to the first sliding block 14, and the follow-up structure includes a first movable sleeve 10 slidably mounted on the first rotating rod 7. The supporting platform 5 is provided with a first cylinder 8, and the telescopic end of the first cylinder 8 is provided with a first movable plate 9 rotatably connected to the first movable sleeve 10; it also includes a connecting rod 16 hinged on the first movable sleeve 10 and hinged to the first sliding block 14, and a first spring 13 is sleeved on the first rotating rod 7, and the two ends of the first spring 13 are respectively in contact with the first movable sleeve 10 and the first support plate 12.

[0064] Furthermore, a first fixing ring 701 is provided at the end of the first rotating rod 7. In the initial state, under the action of the first cylinder 8, the first movable plate 9 is located at the end of the stroke toward the first motor 6, and the first spring 13 is in a compressed state, so that the distance between the first movable plate 9 and the first support plate 12 is maximized. Under the action of the connecting rod 16, the distance between the two first sliding blocks 14 is minimized, so that the distance between the two inner support plates 15 is minimized and smaller than the size of the bottle opening.

[0065] When it is necessary to perform visual inspection on the circumferential outer wall of the bottle body, at this time, the first cylinder 8 works and pushes the first movable plate 9 to move in the direction away from the first motor 6, thereby driving the first movable sleeve 10 to move along the length direction of the first rotating rod 7. Under the action of the first spring 13, the first support plate 12 moves synchronously, thereby driving the inner support plate 15 to move toward the inside of the bottle body. When the first sliding sleeve 11 moves to the position abutting the first fixing ring 701, the inner support plate 15 is inserted into the opening of the bottle body, and the height of the first support plate 12 no longer changes. At this time, the first movable plate 9 continues to move and compresses the first spring 13 through the first movable sleeve 10. At the same time, the first movable sleeve 10 will also drive the connecting rod 16 to move to control the two first movable plates. A sliding block 14 moves along the length direction of the first slide groove 1201 and moves in the direction away from each other to increase the distance between the two inner support plates 15. When the two inner support plates 15 are in contact with the inner wall of the bottle body, it means that the bottle body is fixed. At this time, the first cylinder 8 stops moving, the first motor 6 works, and drives the first rotating rod 7 to rotate, thereby driving the first support plate 12 to rotate through the first sliding sleeve 11, so as to drive the bottle body to rotate around the first rotating rod 7 through the inner support plate 15. Under the action of the visual detector 4, the whole body of the bottle body can be visually inspected. When the bottle body rotates one circle, it means that the inspection is completed. At this time, the first cylinder 8 controls the first movable plate 9 to reset, so that the inner support plate 15 is separated from the inner wall of the bottle body and moves toward the initial position.

[0066] Preferably, when the clamping plate 33 clamps the outer wall of the bottle body and rotates, the opening and bottom of the bottle body and the surrounding area of ​​the bottle body that is not clamped are visually inspected. Since the clamping plate 33 blocks the inspection of a part of the bottle body, the inner support plate 15 clamps the inner wall of the bottle body and drives the bottle body to rotate, so that a comprehensive inspection of the outside of the bottle body can be achieved. With the dual cooperation of the clamping plate 33 and the inner support plate 15, the accuracy and comprehensiveness of the bottle body inspection are ensured.

[0067] A method for high-precision visual inspection of the shape of a multi-station intelligent bottle making machine includes the following steps:

[0068] Step 1: Under the action of the conveyor belt 3, the bottle body is conveyed to the position where it cooperates with the inner support plate 15;

[0069] Step 2: Under the action of the inner diameter support mechanism, control the inner support plate 15 to be inserted into the bottle body, and control the inner support plate 15 to move in a direction away from each other until the inner support plate 15 abuts against the inner wall of the bottle;

[0070] Step 3: The inner diameter support mechanism will control the rotation of the bottle body through the inner support plate 15, so that the outer wall of the bottle body can be visually inspected by the visual detector 4;

[0071] Step 4: After the detection is completed, under the action of the rotation mechanism and the spacing control mechanism, the outer diameter clamping assembly controls the two clamping plates 33 to clamp the outer wall of the bottle body;

[0072] Step 5: The rotating mechanism will control the bottle body to flip through the outer diameter clamping assembly and the clamping plate, so that the visual detector 4 can perform visual inspection on both ends of the bottle body.
