Description

Technical Field

[0001] This application belongs to the field of packaging machine technology, specifically relating to an online quality inspection device for solid welding wire packaging cartons. Background Technology

[0002] Solid welding wire, as a metal product, is quite sensitive to the temperature and humidity conditions of the storage environment. During transportation, it is necessary to avoid damage to the packaging caused by external impacts. Cardboard boxes, as the direct protective carrier, are the core barrier against adverse external factors due to their forming quality.

[0003] Inadequately pressed folds significantly reduce the structural stability of the cardboard box. During stacking, storage, or transport, the folds are prone to warping and the box may break. This can allow external dust, moisture, and other impurities to enter the box. Furthermore, improper sealing can lead to seal failure, allowing moisture from the air to penetrate and contact the welding wire surface, causing it to become damp and corrode. This can severely negatively impact the performance of solid welding wire and even render the product unusable. Current cardboard box packaging inspections typically rely on manual checks. Visual inspection and touch alone are insufficient to guarantee quality and accurately assess the pressure of the folds. Even if the folds don't warp, insufficient adhesive may exist, potentially leading to openings during handling and long-distance transport under vibration or other external forces. This can result in packaging failure, potentially causing internal components to fall out or be damaged, affecting subsequent use. Utility Model Content

[0004] This application provides an online quality inspection device for solid welding wire packaging cartons to solve the problem of not being able to accurately judge the compressive strength of the folded edges. Some packaging cartons may not have curled edges, but they may have insufficient adhesive. This may cause the packaging to fail due to openings under external forces such as vibration during subsequent handling and long-distance transportation.

[0005] The technical solution adopted in this application is as follows: An online quality inspection device for solid welding wire packaging cartons includes: The conveying device includes a gantry frame and a roller conveyor; the roller conveyor has an output end parallel to the conveying direction and a sorting end perpendicular to the conveying direction. The detection device includes a distance sensor assembly, a first folding detection device, and a second folding detection device; the distance sensor assembly is connected to the gantry support and is used to detect the size of the packaging carton; the first folding detection device and the second folding detection device are respectively connected to both sides of the roller conveyor and are used to detect the folding fit of the packaging carton. The sorting device includes a rejection assembly, a blocking assembly, and a stopper connected to a roller conveyor; the blocking assembly is used to block qualified packaging cartons from falling; the rejection assembly is used to push unqualified packaging cartons to the sorting end; and the stopper is connected to one side of the sorting end of the roller conveyor to block unqualified packaging cartons from falling from the sorting end.

[0006] The ranging sensor assembly includes a first laser ranging sensor, a second laser ranging sensor, and a third laser ranging sensor; the first laser ranging sensor is connected to the top inner wall of the gantry support, the second laser ranging sensor is connected to one side of the gantry support, and the third laser ranging sensor is connected to the other side of the gantry support.

[0007] The first folding detection device includes a first support assembly and a first pressure sensor; the first support assembly is connected to the frame of the roller conveyor; the first pressure sensor is connected to the inner side of the first support assembly facing the roller conveyor.

[0008] The first support assembly includes a first drive device, a first spring body, a first support frame, and a first positioning plate; the first drive device is connected to the roller conveyor, the first support frame is connected to the first drive device, a plurality of the first spring bodies are connected to the inner side of the first support frame facing the roller conveyor, and the first positioning plate is connected to the end of the first spring body, such that the first positioning plate has a floating amount along the conveying direction perpendicular to the roller conveyor; a first pressure sensor is connected to the first positioning plate.

[0009] The first positioning plate has a first connecting section, a second connecting section and a third connecting section; the first connecting section is connected to the side of the second connecting section facing the starting end of the roller conveyor, and the third connecting section is connected to the side of the second connecting section facing the output end of the roller conveyor.

[0010] The first connecting section has a first guide surface that is inclined to the second connecting section, such that the first positioning plate forms a first guide end that is inclined toward the outside of the roller conveyor.

[0011] The third connecting section has a second guide surface that is inclined to the second connecting section, such that the first positioning plate forms a second guide end that is inclined toward the outside of the roller conveyor.

[0012] The second folding detection device includes a second support assembly and a second pressure sensor; the second support assembly is connected to the frame of the roller conveyor; the second pressure sensor is connected to the inner side of the second support assembly facing the roller conveyor.

[0013] The spacing between the first pressure sensor and the second pressure sensor can be adapted to the width of the packaging carton, so that one side of the packaging carton in the width direction can fit with the first pressure sensor and the other side of the packaging carton in the width direction can fit with the second pressure sensor, so that the first pressure sensor and the second pressure sensor can collect the compaction pressure of the two folded edges of the packaging carton.

[0014] The rejection assembly includes an ejector cylinder that can move in the width direction of the roller conveyor to push non-conforming cartons into the sorting end.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The conveying device of this application can transport the packaging carton. During the transport of the packaging carton along the roller conveyor, when it passes through the gantry support, the distance measuring sensor assembly, the first folding detection device, and the second folding detection device connected to the gantry support can further detect the packaging carton. The distance measuring sensor assembly can collect the actual width and height dimensions of the packaging carton and transmit them to the PLC controller. The PLC controller can calculate the dimensions of the packaging carton, including the length and height dimensions, based on the data collected by the distance measuring sensor assembly, and then compare them with a preset standard ruler. The dimensions of the packaging carton are compared to check whether the packaging dimensions are qualified. Furthermore, the first folding edge detection device is set on one side of the gantry support, and the second folding edge detection device is set on the other side of the gantry support. The first folding edge detection device can correspond to the folding edge position on one side of the packaging carton. The first pressure sensor inside can fit with the folding edge to collect the compaction pressure data of the folding edge. If the pressure value is lower than the preset threshold, it can be determined that the folding edge is not properly fitted. Similarly, the second folding edge detection device can detect whether the folding edge on the other side is properly fitted, thereby realizing the detection of qualified folding edges of the packaging carton.

[0016] The PLC controller can comprehensively judge whether the packaging carton is properly packaged by combining the dimensional data collected by the ranging sensor component and the pressure data collected by the first or second pressure sensor through dual detection, comparative analysis, and logical judgment. This allows for online inspection of packaging cartons directly after processing on the production line, saving subsequent quality inspection processes, improving the efficiency of mass production, eliminating the need for manual intervention, reducing labor costs and intensity, and coordinating with the high-speed production line cycle. It can adjust the detection parameters in real time according to the different specifications of solid welding wire packaging cartons, thereby achieving high-quality, high-speed inspection with a missed detection rate of ≤0.1%, realizing accurate online inspection of packaging cartons.

[0022] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0023] This application relates to an online quality inspection device for solid welding wire packaging cartons, such as... Figure 1 As shown, it includes: The conveying device includes a gantry support 2 and a roller conveyor 1; the roller conveyor 1 has an output end 14 parallel to the conveying direction and a sorting end 16 perpendicular to the conveying direction. The detection device includes a distance sensor assembly, a first folding detection device 6, and a second folding detection device 7. The distance sensor assembly is connected to the gantry support 2 and is used to detect the size of the packaging carton. The first folding detection device 6 and the second folding detection device 7 are respectively connected to both sides of the roller conveyor 1 and are used to detect the folding fit of the packaging carton. The sorting device includes a rejection assembly, a blocking assembly 13, and a stopper connected to the roller conveyor. The rejection assembly and the blocking assembly 13 are connected to one side of the output end 14 of the roller conveyor 1. The rejection assembly is used to push unqualified packaging cartons to the sorting end 16, and the blocking assembly 13 is used to prevent qualified packaging cartons from falling from the output end 14. The stopper is connected to one side of the sorting end 16 of the roller conveyor 1 and is used to block unqualified packaging cartons from falling from the roller conveyor 1.

[0024] The solid welding wire packaging carton online quality inspection device of this application is used to detect the qualification of the packaging carton after packaging. After the packaging carton is packaged, its two sides will have folded edges. Whether the fit of the folded edges is intact, whether there are any folded edges that are not fitted, or whether some folded edges are loose at some angles and not fully fitted, can easily lead to the packaging failure during subsequent transportation due to external vibration or force during handling. In severe cases, it may cause the internal parts of the packaging to fall out or be damaged, affecting subsequent use. Therefore, the conveying device of this application can complete the conveying of the packaging carton. During the transportation of the packaging carton along the roller conveyor 1, when it passes through the gantry support 2, the distance measuring sensor assembly, the first folding detection device 6 and the second folding detection device 7 connected on the gantry support 2 can further detect the packaging carton. The distance measuring sensor assembly can collect the actual width and height dimensions of the packaging carton and transmit them to the PLC controller. The PLC controller can calculate the dimensions of the packaging carton, including the length and height dimensions, based on the data collected by the distance measuring sensor assembly, and then compare them with the preset standard dimensions. The packaging dimensions of the carton are compared to check if they are within acceptable limits. Furthermore, a first folding edge detection device 6 is located on one side of the gantry support 2, and a second folding edge detection device 7 is located on the other side of the gantry support 2. The first folding edge detection device 6 corresponds to the folding edge position on one side of the carton, and its internal first pressure sensor 62 is in contact with the folding edge to collect the compaction pressure data. If the pressure value is lower than a preset threshold, it can be determined that the folding edge is not properly aligned. Similarly, the second folding edge detection device 7 can detect whether the folding edge on the other side is properly aligned, thereby achieving the detection of the acceptable folding edge of the carton.

[0025] The PLC controller can comprehensively judge whether the packaging carton is properly packaged by combining the dimensional data collected by the ranging sensor component and the pressure data collected by the first pressure sensor 62 or the second pressure sensor 72 through dual detection, comparative analysis and logical judgment. This allows for direct online inspection of the packaging carton after processing on the production line, saving subsequent quality inspection processes, improving the efficiency of mass production, eliminating the need for manual intervention, reducing labor costs and intensity, and coordinating with the high-speed production line cycle. It can adjust the detection parameters in real time according to the different specifications of solid welding wire packaging cartons, achieving high-quality, high-speed inspection with a false negative rate of ≤0.1%.

[0026] In a preferred embodiment, the ranging sensor assembly includes a first laser ranging sensor 3, a second laser ranging sensor 4, and a third laser ranging sensor 5; the first laser ranging sensor 3 is connected to the top inner wall of the gantry support 2, the second laser ranging sensor 4 is connected to one side of the gantry support 2, and the third laser ranging sensor 5 is connected to the other side of the gantry support 2.

[0027] The first laser rangefinder 3 is connected to the top of the gantry bracket 2, positioned at the center of the top. Its detection accuracy is ±0.1mm. It collects the height of the carton in real time and transmits the data to the PLC controller. The second laser rangefinder 4 is connected to one side of the gantry bracket 2, specifically to the side where the first folding detection device 6 is located. It collects the distance between the left side of the carton and the second laser rangefinder 4 (as shown in the figure). The third laser rangefinder 5 is connected to the same side as the second folding detection device. It collects the distance between the right side of the carton and the third laser rangefinder 5 (as shown in the figure). The data collected by the second and third laser rangefinders are uploaded to the PLC controller. The PLC controller calculates the actual dimensions of the carton, including length and width, based on the collected data, thereby determining whether the carton meets the required dimensions and indirectly assessing the degree of proper packaging.

[0028] In a preferred embodiment, the first folding detection device 6 includes a first support assembly 61 and a first pressure sensor 62; the first support assembly 61 is connected to the frame of the roller conveyor 1; the first pressure sensor 62 is connected to the inner side of the first support assembly 61 facing the roller conveyor 1.

[0029] The first support assembly 61 is used to connect the first pressure sensor 62 to one side of the roller conveyor 1. Therefore, the first support assembly 61 plays a supporting and positioning role for the first pressure sensor 62. The first support assembly 61 can move back and forth a certain distance relative to the width direction of the roller conveyor 1. The purpose is to achieve adaptive adjustment of the packaging carton so as to detect the adhesion of the side of the packaging carton. This makes it easier for the first pressure sensor 62 to adhere to the side of the packaging carton, thereby facilitating the collection of the compaction pressure of the folded edge of the packaging carton.

[0030] In a preferred embodiment, the first support assembly 61 includes a first driving device, a first spring body, a first support frame, and a first positioning plate; the first driving device is connected to the roller conveyor 1, the first support frame is connected to the first driving device, a plurality of first spring bodies are connected to the inner side of the first support frame facing the roller conveyor 1, the first positioning plate is connected to the end of the spring body, such that the first positioning plate has a floating amount along the conveying direction perpendicular to the roller conveyor 1, and a first pressure sensor 62 is connected to the first positioning plate.

[0031] The first driving device can be a servo motor. The first driving device can be connected to the frame of the roller conveyor 1 and connected to the first support frame. The first support frame can move back and forth along the width direction of the roller conveyor 1 under the driving action of the first driving device, thereby adjusting the position of the first support frame. Multiple first spring bodies are connected to the inner side of the first support frame, and the first positioning plate is connected through the multiple first spring bodies. The first support frame can move back and forth, thereby allowing the first positioning plate to adjust the distance relative to the packaging carton. Then, the first positioning plate can be elastically connected to the first support frame, so that the first positioning plate has a floating amount of back and forth movement, thereby achieving both the bonding of the left and right sides of the packaging carton and the smooth passage of the packaging carton through the first folding detection device 6 and the second folding detection device on both sides.

[0032] In a preferred embodiment, the first positioning plate has a first connecting section, a second connecting section and a third connecting section; the first connecting section is connected to the side of the second connecting section facing the starting end 15 of the roller conveyor 1, and the third connecting section is connected to the side of the second connecting section facing the output end 14 of the roller conveyor 1.

[0033] The first connecting section of the first positioning plate is located on the side of the first positioning plate facing the starting end 15 of the roller conveyor 1, and the third connecting section is located on the side of the first positioning plate facing the output end 14 of the roller conveyor 1. This allows the packaging carton to pass through the first connecting section of the first folding detection device 6, then through the second connecting section, and then be output along the third connecting section when it is transported by the roller conveyor 1. This enables the packaging carton to be smoothly introduced and exported between the first folding detection device 6 and the second folding detection device 7 on both sides, thereby realizing the positioning detection of the packaging carton.

[0034] In a preferred embodiment, the first connecting section has a first guide surface 8 that is inclined to the second connecting section, such that the first positioning plate forms a first guide end that is inclined toward the outside of the roller conveyor 1.

[0035] The first connecting section has a first guide surface 8 that is inclined to the second connecting section. The first guide surface 8 is inclined towards the outside of the roller conveyor 1, so that a flared structure is formed between the first connecting section of the first folding detection device 6 and the first transition section of the second folding detection device. The purpose is to facilitate the smooth guidance of the packaging carton between the first folding detection device 6 and the second folding detection device 7. When the packaging carton is skewed, that is, when it is not in the center position of the gantry support 2 or is not in the conveying direction parallel to the roller conveyor 1, it can be smoothly corrected under the guidance of the first guide surface 8 and the third guide surface 10. This facilitates the next step of the first pressure sensor 62 and the second pressure sensor 72 to be attached to both sides of the packaging carton for compaction pressure detection.

[0036] In a preferred embodiment, the third connecting section has a second guide surface 9 that is inclined to the second connecting section, such that the first positioning plate forms a second guide end that is inclined toward the outside of the roller conveyor 1.

[0037] The third connecting section has a second guide surface 9 that is inclined to the second connecting section. Similarly, the second positioning plate in the second folding detection device has a third transition section. The third transition section has a fourth guide surface 11 that is inclined to the second transition section. A flared structure is formed between the third guide surface 10 and the fourth guide surface 11. The purpose is to facilitate the smooth output of the packaging carton from the first folding detection device 6 and the second folding detection device 7, and to prevent the packaging carton from being stuck and unable to be output smoothly.

[0038] In a preferred embodiment, the second folding detection device includes a second support assembly 71 and a second pressure sensor 72; the second support assembly 71 is connected to the frame of the roller conveyor 1; the second pressure sensor 72 is connected to the inner side of the second support assembly 71 facing the roller conveyor 1.

[0039] The second support assembly 71 includes a second drive device, a second spring body, a second support frame, and a second positioning plate. The second drive device is connected to the roller conveyor 1, the second support frame is connected to the second drive device, a plurality of second spring bodies are connected to the inner side of the second support frame facing the roller conveyor 1, the second positioning plate is connected to the end of the second spring body, such that the second positioning plate has a floating amount along the conveying direction perpendicular to the roller conveyor 1, and the second pressure sensor 72 is connected to the second positioning plate.

[0040] The second drive device can be a servo motor. The second drive device can be connected to the frame of the roller conveyor 1 and connected to the second support frame. The second support frame can move back and forth along the width direction of the roller conveyor 1 under the drive of the second drive device, thereby adjusting the position of the second support frame. Multiple second spring bodies are connected to the inner side of the second support frame, and the second positioning plate is connected through the multiple second spring bodies. The second support frame can move back and forth, so that the second positioning plate can adjust the distance relative to the packaging carton. Then, the second positioning plate can be elastically connected to the second support frame, so that the second positioning plate has a floating amount of back and forth movement, thereby realizing both the bonding of the left and right sides of the packaging carton and the smooth passage of the packaging carton through the first folding detection device 6 and the second folding detection device on both sides.

[0041] Furthermore, the second positioning plate includes a first transition section, a second transition section, and a third transition section. The first transition section is connected to the side of the second transition section facing the starting end 15 of the roller conveyor 1, and the third transition section is connected to the side of the second transition section facing the output end 14 of the roller conveyor 1. The first transition section has a third guide surface 10 inclined to the second transition section, and the third transition section has a fourth guide surface 11 inclined to the second transition section.

[0042] In a preferred embodiment, the spacing between the first pressure sensor 62 and the second pressure sensor 72 can be adapted to the width of the packaging carton, so that one side of the packaging carton in the width direction can fit with the first pressure sensor 62 and the other side of the packaging carton in the width direction can fit with the second pressure sensor 72, so that the first pressure sensor 62 and the second pressure sensor 72 can collect the compaction pressure of the two folded edges of the packaging carton.

[0043] The first pressure sensor 62 can move back and forth along the width direction of the roller conveyor 1 under the action of the first driving device. Similarly, the second pressure sensor 72 can move back and forth along the width direction of the roller conveyor 1 under the action of the second driving device, so that the distance between the first pressure sensor 62 and the second pressure sensor 72 can be adjusted to match the width between the two sides of the packaging carton, so that the distance between the first pressure sensor 62 and the second pressure sensor 72 can allow the packaging carton to pass through smoothly. Since the first positioning plate connected to the first pressure sensor 62 can be elastically connected to the first support... On the support frame, the second positioning plate connected to the second pressure sensor 72 can be elastically connected to the second support frame, thereby allowing for fine-tuning relative to both sides of the packaging carton. This enables the first pressure sensor 62 to be attached to the left side of the packaging carton and the second pressure sensor 72 to be attached to the right side of the packaging carton, collecting the compaction pressure data of the folded edge. When it is determined that the pressure data is less than the preset threshold, it can be determined that the folded edge is not properly attached. The PLC controls the rejection component to push the unqualified packaging carton into the sorting end 16 for collection, which is beneficial for subsequent rework.

[0044] In a preferred embodiment, the rejection assembly includes an ejector cylinder 12, which is movable in the width direction of the roller conveyor 1 to push non-conforming cartons into the sorting end 16.

[0045] The ejector cylinder 12 is connected to the frame of the roller conveyor 1 and is connected to the side near the output end 14 of the roller conveyor 1. When the PLC determines that there are unqualified products in the packaging carton, it controls the ejector cylinder 12 to extend outward. The extension rod of the ejector cylinder 12 can push the packaging carton to move towards the sorting end 16 on the other side of the roller conveyor 1. The sorting end 16 of the roller conveyor 1 is vertically connected to the conveying direction side of the roller conveyor 1. The ejector cylinder 12 is set opposite to the sorting end 16. Under the pushing action of the ejector cylinder 12, the packaging carton continues to move towards the sorting end 16. It can move further to the output side of the sorting end 16 and then fall downward. A baffle is also connected to one side of the sorting end 16. The baffle can be driven by a drive motor to move the baffle plate up and down to block the unqualified packaging carton from falling. The unqualified packaging carton can enter the sorting end area and stay for further collection, which is beneficial for the subsequent rework of the unqualified packaging carton. A qualified packaging carton can continue to move along the output direction of the roller conveyor 1 by pushing out cylinder 12, but will stop moving forward under the blocking action of blocking component 13. The blocking component 13 is preferably a blocking cylinder, or the blocking component 13 has a structure in which the blocking cylinder is connected to the blocking partition. The blocking partition can move upward to prevent the packaging carton from continuing to move along the roller conveyor 1. The blocking cylinder can be a hydraulic cylinder or a servo motor connected to the baffle, depending on the actual needs. It is not described in detail, as long as it can block the packaging carton and prevent it from falling from the output end 14 of the roller conveyor 1.

[0046] In addition, it should be noted that a photoelectric switch is also connected to the roller conveyor of this application after the first folding detection device and the second folding detection device. The photoelectric switch is used to detect whether the welding wire in the packaging carton is full or whether there are any empty cavities. The collected data is uploaded to the PLC controller for further judgment to determine whether there is a shortage of welding wire in the packaging carton, so as to further detect whether the packaging requirements are met.
