Detailed implementation manners

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not intended to limit the present utility model.

[0027] Refer to Figures 1 to 3 As shown, an embodiment of the present utility model provides a stamping product quality detection system, including:

[0028] Frame 100; the frame 100 can be a steel structure;

[0029] Conveying mechanism 200, arranged in the frame 100, the conveying mechanism 200 includes a conveying component 210 that conveys along the X direction; the front end of the conveying component 210 is docked with the stamping workshop of the previous process;

[0030] The line body 300 is arranged in the frame 100. The line body 300 includes a quality inspection area 310, a qualified product discharging area 320, and a non-qualified product discharging area 330 arranged in sequence along the X direction. The quality inspection area 310 includes a plurality of quality inspection lights 311 arranged directly above the conveying component 210 and a plurality of quality inspection lights 311 arranged on both sides of the conveying component 210 along the Y direction. The Y direction is perpendicular to the X direction and both are in the horizontal plane. The quality inspection area 310 further includes a 2D line scan inspection system installed above the conveying component 210. The 2D line scan inspection system includes a frame body 312, a moving component 313, a 2D line scan camera 314, and an image processing system. The frame body 312 is connected to the frame 100. The moving component 313 is arranged on the top of the frame body 312. The frame body 312 is a portal frame and straddles above the conveying component 210. The moving component 313 is connected to the 2D line scan camera 314 and is used to drive the 2D line scan camera 314 to move along the Y direction. The image processing system is electrically connected to the 2D line scan camera 314. The qualified product discharging area 320 is arranged on at least one side of the conveying component 210. The non-qualified product discharging area 330 is arranged on at least one side of the conveying component 210.

[0031] After the stamping product is stamped, the stamping product is placed on the conveying component 210. The conveying component 210 transports the stamping product to the quality inspection area 310 of the line body 300. After the inspection is completed, the conveying component 210 transports the qualified stamping products and the unqualified stamping products to the qualified product discharging area and the non-qualified product discharging area 330 respectively, realizing the docking of the upper and lower processes, as well as the centralized storage of qualified products and facilitating subsequent transfer, improving the automation performance and reducing the labor cost. When being transported to the quality inspection area 310, the plurality of quality inspection lights 311 can make the product obtain sufficient light brightness in all directions (except the bottom surface), so as to ensure the accuracy of the inspection. And at the same time, while the 2D line scan inspection system moves in the direction perpendicular to the conveying direction of the stamping product, it scans the outer contour of the stamping product and feeds the result back to the image processing system. The image processing system can judge whether the product contour, size, defects, etc. are qualified. Thus, accurate and rapid product quality inspection is realized, avoiding missed inspections and improving the inspection efficiency. In addition, the distribution of the light can be adjusted by turning on the quality inspection lights 311 at different positions.

[0032] Specifically, through the arrangement of the plurality of quality inspection lights 311 in the quality inspection area 310 of the present application, a better inspection environment is provided for the 2D line scan camera 314 to scan the outer contour of the product, thereby improving the inspection accuracy and avoiding missed inspections. In addition, in the present application, the product completed in the upper process is transmitted to the quality inspection area 310 by the conveying mechanism 200 for inspection, so as to realize the inspection during the transmission process, improve the inspection efficiency, and then transmit it to the qualified product discharging area 320 and the non-qualified product discharging area 330 for buffering.

[0033] Furthermore, the present application further includes a control unit, which is connected to the quality inspection lamp 311 and is used to control the light emission intensity of the quality inspection lamp 311.

[0034] Furthermore, the light emission intensity of the quality inspection lamp 311 is 33%, 66% or 100%. Thus, by adjusting the light emission intensity of the quality inspection lamp 311 through the control unit, the most suitable inspection environment can be provided for the 2D line scan inspection system to detect the product, improving the inspection accuracy.

[0035] Furthermore, there are two conveying components 210, and the two conveying components 210 are arranged in parallel.

[0036] Furthermore, the moving component 313 includes a linear module, and the linear module drives the 2D line scan camera 314 to move. The structure is simple and stable.

[0037] Furthermore, the 2D line scan inspection system further includes a linear array CCD sensor for identifying whether a stamping product passes through. The linear array CCD sensor is electrically connected to the 2D line scan camera 314. When the product moves to the quality inspection area 310 along with the conveying component 210, the linear array CCD sensor detects that a stamping product passes through, and the 2D line scan camera 314 starts to scan the stamping product and feeds back the result to the image processing system. The image processing system can judge whether the product contour, size, defects, etc. are qualified and display the result on the display screen. In this way, the 2D line scan camera 314 does not work when there is no product passing through, and the 2D line scan camera 314 works when there is a product passing through, thus saving energy.

[0038] Furthermore, barcode scanners are provided in the quality inspection area 310, the qualified product discharging area 320, and the unqualified product discharging area 330. The barcode scanner in the quality inspection area 310 is located on the front side of the 2D line scan camera 314. A two-dimensional code is provided on each corresponding stamping product. The stamping product corresponding to the two-dimensional code can be scanned through the barcode scanner, which is convenient for traceability.

[0039] In this way, before the 2D line scan camera 314 scans and inspects, the barcode scanner can scan the stamping product to be inspected and upload the product information to the factory MES system. After the 2D line scan camera 314 scans and passes through the image processing system, the result is correspondingly uploaded to the corresponding product in the factory MES system, thus facilitating traceability. In this way, when the inspected stamping product is transferred to the qualified product discharging area 320 and the unqualified product discharging area 330, the operator can know whether the product is a qualified product or an unqualified product by scanning the two-dimensional code of the stamping product, thus facilitating corresponding disposal of the product.

[0040] Furthermore, the conveying assembly 210 includes a frame, a motor, a transmission belt, a driving wheel and a driven wheel; the motor is mounted on the frame, the driving wheel and the driven wheel are both rotatably connected to the frame, the driving wheel is connected to the driving shaft of the motor, and the transmission belt is wound around the driving wheel and the driven wheel. The conveying assembly 210 has a stable and reliable structure.

[0041] Furthermore, the qualified product unloading area 320 includes a plurality of first unloading stations 321 arranged in sequence along the X direction, and the first unloading station 321 is provided with an elevator 322, and the elevator 322 is lifted and lowered at the first unloading station 321; a material rack 323 for placing stamping products is placed on the elevator 322. In this way, when the operator needs to transport the qualified stamping product to the elevator 322, the elevator 322 can automatically adjust its height, so that the operator does not need to bend over, turn sideways, etc., which reduces fatigue and ensures the safety of the operator. The labor intensity of the operator is reduced.

[0042] Furthermore, the material rack 323 is provided with a sensor for identifying whether the stamped products on the material rack 323 are fully loaded, and the sensor is electrically connected to the material dispatching system. For example, the sensor is a weight sensor. In this way, when the operator completes the placement of qualified stamped products on the elevator 322 and adjusts it to a safe height, the sensor performs detection at the same time. When the sensor detects that it is qualified (that is, the stamped products on the material rack 323 are fully loaded), the dispatching system can automatically call a forklift operator to move the materials. In addition, the lifting control and dispatching control of the elevator 322 can also be manually operated, and the appropriate operation mode can be selected according to the actual situation on site.

[0043] In some embodiments, the qualified product unloading area 320 has 8 first unloading stations 321, and the unqualified product unloading area 330 has 4 second unloading stations 331. Products are cached in the qualified product unloading area 320 and the unqualified product unloading area 330, and operators do not need to track the production line all the time. After the product inspected by the quality inspection area 310 is transported to the qualified product unloading area 320 or the unqualified product unloading area 330 with the conveying component 210, the operator determines whether the product is OK by scanning the code and transfers the product to the corresponding shelf position. Improve efficiency and reduce labor costs.

[0044] The detection and transmission process of this application is as follows:

[0045] 1. The stamping products produced in the upward process (stamping workshop) are transported to the quality inspection area 310 through the conveying assembly 210.

[0046] 2. Adjust the light intensity and distribution of the quality inspection lamp 311, and use the code scanning and 2D line scanning inspection system to inspect the product.

[0047] 3. The products after detection continue to flow towards the rear unloading area (qualified product unloading area 320 or unqualified product unloading area 330) through the conveying component 210.

[0048] 4. The operator at the qualified product unloading area 320 uses a barcode scanner to scan the products to distinguish whether they are qualified. If they are qualified, the operator places the qualified products on the material rack 323 of the elevator 322. In addition, after the sensor recognizes that the material rack 323 is full, it triggers an alarm to prompt the forklift to pick up the materials, calls the material dispatcher to pick up the products and place an empty material rack 323. If the unqualified products continue to be transported backward to the unqualified product unloading area 330.

[0049] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
