Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard delamination defect detection technology, and in particular to a detection device. Background Technology

[0002] In the packaging industry, corrugated cardboard is widely used for packaging various products due to its excellent cushioning, compression resistance, and lightweight properties. Delamination defects in corrugated cardboard have always been a technical challenge. This defect manifests as the surface of a single layer of corrugated base paper separating from the substrate. Because it is difficult to detect in the base paper state, it is mostly discovered only in the finished product stage.

[0003] Currently, in the finished product stage, the method for detecting delamination defects in corrugated cardboard is to fold the carton 180 degrees after gluing and check whether single-layer delamination occurs at the edges. Once a defect is found, a large number of defective products are generated, and such defects cannot be reworked, resulting in serious resource waste and increased costs. In the cardboard production stage, the method for inspecting delamination defects in corrugated cardboard is to forcibly tear and peel the cardboard sample from the edge after it leaves the machine. This detection method is greatly affected by factors such as the force and angle of human operation, making it difficult to guarantee accuracy. It cannot reliably identify potential delamination defects, nor can it detect problems in a timely manner during production, making it difficult to meet the requirements of modern, efficient, and precise production quality control.

[0004] Therefore, there is an urgent need for detection devices to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a detection device that avoids the generation of a large number of defective products and waste of resources in the finished product stage, eliminates human interference, improves detection accuracy, moves the detection process forward to the early stage of production, can promptly detect and stop the production of defective products, and meets the needs of efficient and precise production quality control.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A detection device for detecting delamination defects in a sample, the detection device comprising:

[0008] A base and a support member, the support member being fixed to the base;

[0009] The adsorption rotation component is rotatably connected to the support member. A gap is reserved between the adsorption rotation component and the base, which can accommodate the sample. The adsorption rotation component can adsorb a part of the sample. The rotation of the adsorption rotation component can cause a part of the sample to rotate and fold together, and make a part of the sample form a preset angle with the base. The adsorption rotation component can also press against another part of the sample and make the other part of the sample adhere to the surface of the base.

[0010] As an optional solution for the detection device, the adsorption rotation assembly includes a connector and an adsorption element. The connector is rotatably connected to the support member, and the adsorption element is disposed on the side of the connector facing the base. The adsorption element can adsorb a portion of the sample, and the connector can press against another portion of the sample. The connector can rotate relative to the base and drive the adsorption element to move between a first position and a second position. In the first position, the sample is horizontally sandwiched between the adsorption element and the base and is parallel to the base. In the second position, the portion of the sample adsorbed by the adsorption element and the portion of the sample pressed against by the connector are perpendicular to each other.

[0011] As an alternative to the detection device, the adsorption rotation assembly also includes a handle disposed on the connector, the rotation of which can cause the connector to rotate relative to the base.

[0012] As an alternative to the detection device, the handle extends in a direction perpendicular to the connector. The adsorption rotation assembly also includes a first limiting member disposed on the handle. The extension direction of the first limiting member is perpendicular to the extension direction of the handle. When the adsorption member is in the second position, the first limiting member abuts against the base and is perpendicular to the base.

[0013] As an alternative to the detection device, the detection device also includes a negative pressure fixing member disposed on the base facing the adsorption element, the negative pressure fixing member being configured to fix the position of the sample.

[0014] As an alternative to the detection device, the detection device also includes a negative pressure switch, which is electrically connected to the negative pressure fixing member and can open or close the negative pressure fixing member.

[0015] As an alternative to the detection device, the detection device also includes a stop disposed on the base, the stop being configured to limit the position of the sample end.

[0016] As an optional solution for the detection device, the adsorption rotation assembly further includes a second limiting member disposed on the connecting member. The second limiting member can overlap with the stop member so that when the adsorption member is in the first position, the adsorption member and the base are reserved with the gap.

[0017] As an optional solution for the detection device, the connector is also provided with a connection port that communicates with the adsorption element and can be connected to a negative pressure machine.

[0018] As an optional solution for the detection device, the base is symmetrically provided with support members on both sides, and the support members are provided with through holes. The detection device also includes two screws, which are respectively inserted into the through holes on the corresponding support members and are rotatably engaged with the support members. The ends of the two screws are threadedly connected to the two sides of the connector. Alternatively, the detection device also includes a rotating shaft, which is inserted through the connector and fixedly connected to the connector. The two ends of the rotating shaft are respectively inserted through the two through holes on the two support members and are rotatably connected to the two support members.

[0019] Beneficial effects:

[0020] This invention provides a detection device. During operation, a sample produced in the production stage is placed in the gap between a base and an adsorption-rotating component. The adsorption-rotating component adsorbs a portion of the sample. Its rotation causes this portion of the sample to rotate and fold, forming a predetermined angle between this portion and the base. Simultaneously, the adsorption-rotating component presses against another portion of the sample, causing it to adhere to the base, thus folding the sample and simulating the folding action of a finished product to observe and detect delamination defects. This detection device avoids the generation of a large number of defective products and resource waste in the finished product stage, eliminates human interference, improves detection accuracy, and moves the detection process forward to the early stages of production. It can promptly detect and stop the production of defective products, meeting the requirements for efficient and precise production quality control. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0031] In the packaging industry, corrugated cardboard is widely used for packaging various products due to its excellent cushioning, compression resistance, and lightweight properties. At the finished product stage, the method for detecting delamination defects in corrugated cardboard involves folding the carton 180 degrees after gluing and checking for delamination of the single layer of paper at the edges. Once this defect is detected, a large number of defective products are produced, and these defects cannot be reworked, resulting in significant resource waste and increased costs. At the cardboard production stage, the inspection method for delamination defects involves forcefully tearing the cardboard sample 10 from its edge after it leaves the machine. This method is greatly affected by factors such as the force and angle of human operation, making its accuracy difficult to guarantee. It cannot reliably identify potential delamination defects, nor can it detect problems in a timely manner during production, failing to meet the demands of modern, efficient, and precise production quality control.

[0032] This embodiment discloses a detection device for detecting delamination defects in corrugated cardboard, used to detect delamination defects in sample 10, such as... Figures 1-5 As shown, the detection device includes a base 1, a support 2, and an adsorption rotation assembly 3. The support 2 is fixed to the base 1, and the adsorption rotation assembly 3 is rotatably connected to the support 2. A gap is reserved between the adsorption rotation assembly 3 and the base 1, which can accommodate a sample 10. The adsorption rotation assembly 3 can adsorb a portion of the sample 10. The rotation of the adsorption rotation assembly 3 can cause a portion of the sample 10 to rotate and fold together, and make a portion of the sample 10 form a preset angle with the base 1. The adsorption rotation assembly 3 can also press against another portion of the sample 10 and make the other portion of the sample 10 adhere to the surface of the base 1.

[0033] When this detection device is in operation, the sample 10 produced in the production stage is placed in the gap between the base 1 and the adsorption-rotation component 3. The adsorption-rotation component 3 adsorbs a portion of the sample 10. The rotation of the adsorption-rotation component 3 causes this portion of the sample 10 to rotate, making it form a preset angle with the base 1. At the same time, the adsorption-rotation component 3 also presses against the other portion of the sample 10, causing it to adhere to the base 1, thus folding the sample 10. This simulates the folding action of a finished product to observe and detect delamination defects. This detection device avoids the generation of a large number of defective products and resource waste in the finished product stage, eliminates human interference, improves detection accuracy, and moves the detection process forward to the early stage of production. It can promptly detect and stop the production of defective products, meeting the needs of efficient and accurate production quality control.

[0034] like Figure 5As shown, in this embodiment, the preset angle is 90 degrees, meaning that the portion of sample 10 adsorbed by the adsorption-rotation component 3 is perpendicular to the base 1, while the other portion of sample 10 pressed by the adsorption-rotation component 3 is attached to and parallel to the base 1. In other embodiments, the preset angle is 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc., and is not specifically limited here. This provides diverse operational possibilities for sample 10 processing to adapt to different detection and processing needs, fully demonstrating the flexibility and versatility of the detection device during use.

[0035] like Figures 1-5 As shown, the adsorption-rotation assembly 3 includes a connector 31 and an adsorption element 32. The connector 31 is rotatably connected to the support 2. The adsorption element 32 is disposed on the side of the connector 31 facing the base 1. The adsorption element 32 can adsorb a portion of the sample 10, and the connector 31 can press against the other portion of the sample 10. The connector 31 can rotate relative to the base 1, driving the adsorption element 32 to move between a first position and a second position. In the first position, the sample 10 is horizontally sandwiched between the adsorption element 32 and the base 1, and is parallel to the base 1. In the second position, the portion of the sample 10 adsorbed by the adsorption element 32 is perpendicular to the portion of the sample 10 pressed against by the connector 31. This design simulates the force on cardboard through mechanical adsorption and rotation. Compared with traditional finished product folding or manual tearing detection, it avoids human interference, can detect potential delamination defects in real time during production, reduces the production of defective products, and achieves efficient quality control through standardized and precise operating procedures, reducing resource waste and production costs.

[0036] For ease of description, the portion of sample 10 adsorbed by the adsorbent 32 is defined as the folding part 101. The folding part 101 rotates and folds under the drive of the adsorbent 32 to change its spatial position. The other portion of sample 10 pressed by the connector 31 is defined as the fixing part 102. The fixing part 102 remains fixed under the pressing action of the connector 31.

[0037] like Figures 4-5As shown, in actual operation, sample 10 is placed in the gap between base 1 and adsorption member 32. Adsorption member 32 adsorbs the folded part 101 of sample 10. Connector 31 presses against the fixing part 102 of sample 10, causing the fixing part 102 to adhere to base 1. Connector 31 rotates relative to base 1, causing adsorption member 32 to switch from the first position to the second position, so that the entire sample 10 is folded from a horizontal state parallel to base 1 to a state where the folded part 101 and the fixing part 102 are perpendicular to each other. This detection method moves the folding detection step after the finished product is glued to the production and processing stage. By simulating the folded state of the finished product, when the folded part 101 of sample 10 is perpendicular to the fixing part 102, the reverse pulling action caused by the tension of sample 10 itself is used to visually present the delamination defect. Once sample 10 has a delamination problem, sample 10 will break open under the pulling action, making the delamination defect characteristics clearly visible. This detection method greatly improves the defect identification rate, effectively prevents samples 10 with delamination defects from entering the mass production stage, significantly reduces the defect rate, and ensures product quality.

[0038] like Figure 3 As shown, in this embodiment, the connector 31 is a regular cuboid. Two adjacent sides of the cuboid are connected by a smooth arc transition to form a smooth arc transition portion 314. The two sides forming this arc transition portion 314 are defined as the first side 315 and the second side 316. The first side 315 corresponds to the position of the base 1 and is provided with an adsorption member 32. The end of the connector 31 near the arc transition portion 314 is rotatably connected to the support member 2. When the connector 31 rotates relative to the base 1 around the support member 2, the arc transition portion 314 and the second side 316 press against the fixing portion 102 of the sample 10, so that the folded portion 101 and the fixing portion 102 are perpendicular to each other. The arc transition portion 314 and the second side 316 can gently press against the fixing portion 102 of the sample 10, effectively improving the accuracy and reliability of the detection.

[0039] In other embodiments, the connector 31 is a regular cuboid. When the connector 31 rotates relative to the base 1 around the support 2, one side of the cuboid and the side adjacent to it press against the fixing part 102 of the sample 10 so that the folding part 101 and the fixing part 102 are perpendicular to each other. This is not specifically limited here.

[0040] like Figure 1 and Figure 3As shown, in this embodiment, the first side 315 of the connector 31 is provided with a mounting groove 312, and the adsorption component 32 is installed in the mounting groove 312. The mounting groove 312 on the connector 31 provides precise installation positioning for the adsorption component 32, ensuring that the adsorption component 32 is firmly fitted into the side of the connector 31 facing the base 1. This design not only facilitates the quick installation and disassembly of the adsorption component 32, which is beneficial for later maintenance and replacement, but also effectively prevents the adsorption component 32 from shifting or loosening during the detection process, ensuring the stability and uniformity of its adsorption force on the sample 10, thereby improving the reliability and stability of the adsorption rotation assembly 3 when detecting delamination defects in the sample 10, and ensuring the accuracy of the detection results.

[0041] like Figures 1-3 As shown, the adsorption rotation assembly 3 also includes a handle 33, which is mounted on the connector 31. Rotating the handle 33 causes the connector 31 to rotate relative to the base 1. The handle 33 provides a convenient point of leverage for operation. Operators can flexibly control the adsorption component 32 to switch between the first and second positions by rotating the handle 33, allowing the sample 10 to be folded as needed. This effectively improves detection efficiency, reduces human error, and more efficiently detects delamination defects in the sample 10, ensuring production quality.

[0042] like Figures 3-5 As shown, the handle 33 extends in a direction perpendicular to the connector 31. The adsorption rotation assembly 3 also includes a first limiting member 34, which is disposed on the handle 33. The extension direction of the first limiting member 34 is perpendicular to the extension direction of the handle 33. When the adsorption member 32 is in the second position, the first limiting member 34 abuts against the base 1 and is perpendicular to the base 1. This precisely limits the rotation range of the adsorption member 32, ensuring that the folding part 101 can accurately reach the required vertical state for layer detection, avoiding inaccurate detection due to excessive rotation, ensuring the stability and standardization of the detection operation, and improving the reliability of the detection results.

[0043] In this embodiment, the first limiting member 34 is located on the side of the handle 33 away from the connector 31, which can fully utilize the lever effect to achieve effective limiting with less force. When the adsorption member 32 rotates to the second position, the first limiting member 34 can precisely abut against the base 1 and remain perpendicular, ensuring accurate positioning of the adsorption member 32. This arrangement avoids spatial interference with the connector 31, ensures smooth operation of the adsorption rotation assembly 3, thereby improving the stability of the sample 10's posture during detection and enhancing the reliability of the detection results.

[0044] In this embodiment, the handle 33 is a cuboid. In other embodiments, the handle 33 may be an irregularly shaped part, a curved part, etc., and no specific limitation is made here. In this embodiment, the first limiting member 34 is a cuboid. In other embodiments, the first limiting member 34 may be an irregularly shaped part, etc. It is sufficient that when the adsorption member 32 rotates to the second position, the first limiting member 34 abuts against the base 1 and is perpendicular to the base 1, and the folding part 101 and the fixing part 102 are perpendicular to each other, and no specific limitation is made here.

[0045] In this embodiment, the number of first limiting members 34 is one. In other embodiments, the number of first limiting members 34 can be adjusted adaptively according to the length of the handle 33, that is, the number of first limiting members 34 can be two, three, four, etc., and no specific limitation is made here.

[0046] like Figure 1 , Figures 4-5 As shown, the detection device also includes a negative pressure fixing component 4, which is disposed on the base 1 facing the adsorption component 32. The negative pressure fixing component 4 is used to fix the position of the sample 10. By fixing the position of the sample 10 through the principle of negative pressure adsorption, the sample 10 can be effectively prevented from sliding or shifting when the adsorption rotation component 3 performs adsorption and flipping detection on the sample 10. This ensures that the sample 10 is always in the accurate detection position during the detection process, avoids detection errors caused by position changes, and greatly improves the accuracy and reliability of the detection results.

[0047] It is worth noting that the adsorption force of the adsorption element 32 and the negative pressure fixing element 4 are designed differently, with the adsorption force of the adsorption element 32 being greater than that of the negative pressure fixing element 4. During testing, the adsorption element 32, with its stronger adsorption force, drives the folding part 101 of the sample 10 to fold; at the same time, the fixing part 102 of the sample 10 remains stable under the continuous adsorption of the negative pressure fixing element 4, and combined with the pressing action of the connecting part 31, further ensures that the fixing part 102 is tightly attached to the base 1.

[0048] like Figure 1 , Figures 4-5 As shown, the detection device also includes a negative pressure switch 5, which is electrically connected to the negative pressure fixing component 4. The negative pressure switch 5 can open or close the negative pressure fixing component 4, allowing for flexible control of its operation. Before detection, the operator opens the negative pressure switch 5 to generate an adsorption force on the negative pressure fixing component 4, quickly stabilizing the sample 10. After detection, the operator closes the negative pressure switch 5 to release the negative pressure, facilitating the removal of the sample 10. This design enables convenient and controllable negative pressure fixing operations, preventing accidental displacement or damage to the sample 10 during fixing and disassembly, effectively improving the efficiency and safety of the detection process.

[0049] like Figure 1 , Figures 4-5As shown, the detection device also includes a stop 6, which is mounted on the base 1 and is used to limit the position of the end of the sample 10. When performing delamination defect detection on the sample 10, the stop 6 serves as a positioning reference, ensuring that the sample 10 is placed in a uniform and standardized position, avoiding any impact on the detection effect of the adsorption-rotation assembly 3 on the sample 10 due to placement deviations. Simultaneously, it effectively prevents excessive movement of the sample 10 during the detection process, ensuring the stability and consistency of the detection operation, thereby improving the accuracy and reliability of the detection results.

[0050] like Figures 1-5 As shown, the adsorption rotation assembly 3 also includes a second limiting member 35, which is disposed on the connecting member 31. The second limiting member 35 can overlap with the stop member 6 so that when the adsorption member 32 is in the first position, a gap is reserved between the adsorption member 32 and the base 1. This can regulate the placement space of the sample 10, prevent the adsorption member 32 from directly contacting and squeezing the sample 10, and effectively protect the integrity of the sample 10; at the same time, it ensures that the sample 10 is stable in the initial state of detection, improving the standardization of the detection operation and the reliability of the detection results.

[0051] like Figure 2 As shown, in this embodiment, there are two second limiting members 35, which are respectively disposed on both sides of the connector 31. When the two second limiting members 35 overlap with the stop member 6, they can limit the adsorption member 32 from both sides, so that the adsorption member 32 is subjected to more even force while leaving a gap between the first position and the base 1, effectively avoiding the offset and shaking caused by unilateral limiting, and significantly enhancing the stability and reliability of the adsorption rotation assembly 3. In other embodiments, the number of second limiting members 35 can also be three, four, five, six, etc., which is not specifically limited here.

[0052] like Figure 1 , Figures 3-5 As shown, the connector 31 is also provided with a connection port 311, which communicates with the adsorption element 32 and can be connected to a negative pressure generator. This ensures a stable supply of adsorption force, effectively avoiding the problem of sample 10 falling off or uneven adsorption affecting the test results due to insufficient adsorption force. At the same time, the standardized connection port 311 facilitates equipment maintenance and upgrades, and can be flexibly adapted to different negative pressure generators, enhancing the versatility and reliability of the testing device.

[0053] like Figure 2As shown, symmetrical support members 2 are provided on both sides of the base 1. Each support member 2 has a through hole 21. The detection device also includes two screws 7, each screw 7 passing through the corresponding through hole 21 on the support member 2 and rotatably engaging with it. The ends of the two screws 7 are threadedly connected to both sides of the connector 31. On one hand, the symmetrically arranged support members 2 on both sides of the base 1, in conjunction with the screws 7, provide a stable and flexible support structure for the adsorption-rotation assembly 3. On the other hand, the screws 7 passing through the through holes 21 of the support members 2 and rotatably engaging ensures that the connector 31 can rotate smoothly, preventing shaking during the detection process. Simultaneously, the threaded connection between the ends of the two screws 7 and the sides of the connector 31 facilitates disassembly, maintenance, installation, and debugging.

[0054] In other embodiments, the detection device further includes a rotating shaft, through which a connector 31 passes and is fixedly connected. Two through holes 21 on two support members 2 are respectively passed through both ends of the rotating shaft, and it is rotatably connected to the two support members 2. The rotating shaft provides a stable axis of rotation for the adsorption-rotation assembly 3. This structure ensures that the movement trajectory of the adsorption member 32 is precisely controllable when the connector 31 drives it to switch between the first and second positions, avoiding deviation or shaking. This ensures that the sample 10 is subjected to uniform force and its position is fixed during the folding detection process, effectively improving the stability and reliability of the detection operation, while simplifying the assembly and maintenance process of the adsorption-rotation assembly 3.

[0055] In this embodiment, the connector 31 is provided with a mounting hole 313, and different structural forms can be switched according to different assembly requirements of the detection device. When the screw 7 is selected as the transmission component, the mounting hole 313 is set as an internal thread hole, which achieves a stable connection through the external thread of the screw 7, ensuring the transmission accuracy and structural stability of the adsorption rotation component 3; when the rotating shaft is used as the transmission component, the mounting hole 313 is converted into a through hole, providing a through channel for the rotating shaft, realizing the fixed assembly of the rotating shaft and the connector 31, and enhancing the flexibility and practicality of the device configuration.

[0056] In summary, as Figure 1 , Figures 4-5 As shown, the general working process of this detection device is as follows:

[0057] (1) As Figure 4 As shown, rotate the handle 33 at a small angle to slightly lift the connector 31, clamp the sample 10 between the adsorption component 32 and the negative pressure fixing component 4, use the stop component 6 to position the end of the sample 10, and turn on the negative pressure switch 5 to fix the position of the sample 10.

[0058] (2) Figure 1 As shown, turn the handle 33 back, the second limiting member 35 overlaps the stop member 6, the connection port 311 connects to the negative pressure machine, the adsorption member 32 adsorbs the folded part 101 of the sample 10, and the negative pressure fixing member 4 adsorbs the fixing part 102 of the sample 10.

[0059] (3) Figure 5 As shown, the adsorption member 32 rotates from the first position to the second position, the adsorption member 32 adsorbs the folded part 101 of the sample 10, the connecting member 31 presses against the fixing part 102, the folded part 101 and the fixing part 102 are perpendicular to each other, and the delamination defect of the sample 10 is detected by observing whether the fold or edge of the sample 10 is delaminated.

[0060] (4) Figure 1 As shown, after the test is completed, turn off the negative pressure switch 5, turn the handle 33 back, take out the sample 10, and complete the test for one layer defect.
