Description

Technical Field

[0001] This utility model relates to the technical field of visual inspection, specifically to a packaging defective product rejection device with visual inspection. Background Technology

[0002] In traditional packaging production lines, defective product rejection mainly relies on manual visual inspection or basic photoelectric sensors, which suffers from low efficiency, high false negative rates, and poor stability. With the upgrading of industrial automation, intelligent sorting technology based on machine vision has gradually emerged. Early systems used simple cameras paired with image processing algorithms to detect obvious defects (such as damage and stains) through threshold segmentation. However, limited by algorithm accuracy and hardware performance, the recognition rate for complex defects (such as minor cracks and pattern misalignment) was insufficient, and it was difficult to adapt to the pace of high-speed production lines. Furthermore, mechanical rejection devices mostly use pneumatic push rods or flipping mechanisms, whose dynamic response speed and coordination with the vision system are insufficient, leading to false rejections or missed rejections. Existing technologies urgently need integrated innovation of high-frame-rate industrial cameras, deep learning algorithms, and high-precision actuators to achieve closed-loop control of microsecond-level detection and millisecond-level rejection.

[0003] Application number CN202020089942.2 discloses a defective product transfer device for an automatic inspection and packaging machine, including a mounting frame, an adjusting frame, and a transmission frame. The transmission frame is movably mounted inside the mounting frame via a sliding groove. A shaft frame is movably mounted inside the transmission frame. A fixing frame is bolted to the bottom of the shaft frame. A clamp is movably mounted inside the fixing frame. An adjusting frame is bolted to the top of the transmission frame. This invention features an adjustable frame mounted on top of the transmission frame, allowing for height adjustment to accommodate different product specifications. This broadens the device's applicability to various product sizes. The clamps enable rapid positioning and gripping of defective products, facilitating accurate removal and preventing missed removal, thus ensuring efficient defective product removal. However, a drawback exists: during inspection, the device removes defective items by clamping, which introduces a lag in removal efficiency, impacting production capacity. Utility Model Content

The other side of the rocking rod 405 is fixedly installed at the bottom of the rotating machine 406. A control device 408 is connected to the rear side of the rotating machine 406 through a brake 407.

[0027] By installing a control diversion component 4 on the device, defective or unqualified products captured during the inspection process can be diverted and exported through the control diversion component 4 when using the device, thereby achieving the effect of rejection and avoiding the tedious work of manual sorting afterwards.

[0028] The bracket assembly 1 includes a support column 101, a mounting clip 102 fixedly installed at the bottom of the support column 101, and a mounting side plate 104 fixedly installed at the top of the support column 101.

The device is moved to a suitable position by the movable roller 103 inside the mounting clip 102 at the bottom of the bracket assembly 1, and then the device is fixed.

[0029] The conveying assembly 2 includes a rotary motor 201, which is mounted on one end of the outer wall of the mounting side plate 104 via a mounting bracket 202. An active roller 203 is fixedly mounted on the inner side of the rotary motor 201, and a conveyor belt 204 is mounted on the outer side of the active roller 203. A positioning roller is mounted on the other end of the inner side of the conveyor belt 204. The positioning roller and the active roller 203 are positioned on both sides between the two mounting side plates 104. When the rotary motor 201 of the conveying assembly 2 is started, the active roller 203 is driven to rotate, and the positioning roller is driven to rotate through the conveyor belt 204, so that the packaged product is conveyed along the conveyor belt 204. The description of the conveying assembly 2 clearly presents the power transmission and product conveying process. The product moves with the conveyor belt 204 to below the detection lens 305.

[0030] The height adjustment detection component 3 includes a mounting base 301. Two mounting bases 301 are fixedly installed on the outer walls of two mounting side plates 104.

[0031] The control device 408 and the rotating machine 406 are fixedly mounted on the top of the mounting plate 104 via the fixed mounting bracket 409. The collected image information is transmitted to the control device 408. The control device 408 is pre-set with the standard parameters for qualified products. By comparing the image data with the standard parameters, it is determined whether the product is defective. This indicates the installation position of the control device 408, ensuring the stability of signal transmission and control. If the product is determined to be defective, the control device 408 controls the rotating machine 406 to operate via the brake 407, which drives the rocker arm 405 to shake the guide rail plate 403, changing the direction of defective product conveying.

[0032] The diversion track assembly 5 includes a positioning bracket 501, which is fixedly installed on the inner wall of the mounting side plate 104. Limiting side plates 502 are fixedly installed on both sides of the positioning bracket 501. The limiting side plates 502 are correspondingly arranged on the top two sides of the conveyor belt 204. A partition 503 is provided between the two limiting side plates 502. The partition 503 is fixedly installed at the bottom middle of the positioning bracket 501.

[0033] Using the detection lens 305 in the height adjustment detection component 3, based on visual recognition technology, images of packaged products on the conveyor component 2 are acquired. The height adjustment detection component 3 clarifies the installation structure of the detection lens 305, providing a hardware foundation for image acquisition. The acquired image information is transmitted to the control device 408. The control device 408 pre-sets the standard parameters for qualified products. By comparing the image data with the standard parameters, it determines whether the product is defective. This clarifies the installation position of the control device 408, ensuring the stability of signal transmission and control. If it is determined to be defective, the control device 408 controls the rotating machine 406 to operate through the brake 407, causing the rocker arm 405 to shake the guide rail plate 403, changing the direction of defective product conveying. If it is a qualified product, it continues to be conveyed along the conveyor belt 204. The support component and conveyor component provide a basic motion track for product conveying and defective product rejection. During operation, the device is moved to a suitable position by the moving roller 103 in the mounting clamp 102 at the bottom of the support component 1, and then the device is fixed. According to the product specifications, the height adjustment detection component 3 uses a pneumatic telescopic pump 302 to adjust the height of the detection lens 305. The structure and operation of the height adjustment detection component 3 are explained in detail. The rotary motor 201 of the conveyor component 2 is started, driving the drive roller 203 to rotate. This, in turn, drives the positioning roller to rotate via the conveyor belt 204, causing the packaged product to be conveyed along the conveyor belt 204. The description of the conveyor component 2 clearly presents the power transmission and product conveying process. The product moves along the conveyor belt 204 to below the detection lens 305, where the detection lens 305 captures an image of the product and transmits the information to the control device 408. The component structure ensures accurate detection. To assess the feasibility of measurement and signal transmission, the control device 408 compares the image information with preset standard parameters to determine whether the product is qualified. The installation position of the control device 408 is determined to ensure its stable operation. Defective products are controlled by the control device 408 to rotate the machine 406, which drives the rocking arm 405 to shake the guide rail plate 403, causing it to enter the specific track of the diversion track assembly 5. Qualified products are normally conveyed along the conveyor belt 204. The structure of the diversion assembly 4 and the diversion track assembly 5 is controlled to achieve the diversion and rejection of defective products. Defective products are collected to a designated location under the guidance of the limiting side plate 502 and partition plate 503 of the diversion track assembly 5.
