Description

TECHNICAL FIELD

[0001] The present application relates to the toothpaste box defective product detection technical field, and in particular to a defective product detection and classification device. BACKGROUND

[0002] In the production process of toothpaste, after the toothpaste box is filled, it needs to be detected for quality to remove defective products and ensure that the products flowing into the market meet the quality standards; in the existing toothpaste box filling detection system, visual detection technology has been partially applied, but generally the toothpaste boxes are placed on a conveyor belt for detection one by one, which cannot fully cover all visible parts of the toothpaste box. For example, the front of the toothpaste box may have problems such as irregular label pasting and printing defects, while the back may have appearance damage caused by deformation of the box body or being accidentally touched by other equipment; only detecting one side will cause the defective products on the other side to be missed, resulting in some products with quality problems being mixed with qualified products, thereby reducing the overall quality of the products; in addition, the existing technology often relies on manual flipping, which is costly.

[0003] In view of the problem that the related art lacks a design for flipping the toothpaste box, which makes it only possible to detect one side of the toothpaste box, no effective solution has been proposed so far. SUMMARY

[0059] The recycling box 5 is located at the pushing end of the rejection and overturning assembly 4, so that the toothpaste box can be caught when the toothpaste box is pushed out by the rejection and overturning assembly 4.

[0060] As can be seen from the above description, in the embodiment of the application, the detection assembly 2 and the rejection and overturning assembly 4 are sequentially and spacedly arranged, the detection assembly 2, the conveying assembly 3, the rejection and overturning assembly 4 and the recycling box 5 are installed on the top of the machine table 1; the conveying assembly 3 is located at the middle of the top of the machine table 1; the detection assembly 2 and the rejection and overturning assembly 4 are located at the same side of the conveying assembly 3 and are sequentially and spacedly arranged along the conveying direction of the conveying assembly 3; the detection end of the detection assembly 2 faces the conveying assembly 3; the recycling box 5 is located at the pushing end of the rejection and overturning assembly 4, so as to achieve the purpose of detecting two surfaces of the toothpaste box respectively and pushing the defective product into the recycling box 5, thereby realizing the technical effect of fully detecting the toothpaste box and further solving the technical problem that only one surface of the toothpaste box can be detected due to the lack of design of overturning the toothpaste box.

[0062] Preferably, the bracket 21 comprises a base 211 fixedly installed on the top of the machine table 1 and located at the rear side of the conveying assembly 3.

[0063] The telescopic cylinder 212 is fixedly installed on the base 211 along the front-rear direction.

[0064] The first sliding block 213 is slidingly installed on the base 211 and connected with the piston rod of the telescopic cylinder 212, and is used to drive the first sliding block 213 to slide along the base 211 by the telescopic cylinder 212;

[0065] The first sliding rail 214 is fixedly installed on the first sliding block 213 along the left-right direction;

[0066] The second sliding block 215 is slidingly installed on the first sliding rail 214, and the first sliding rail 214 is rotatably installed with a knob, and the knob is threadedly connected with the second sliding block 215, so that the left-right position of the second sliding block 215 can be adjusted by rotating the knob;

[0067] The second sliding rail 216 is fixedly installed on the second sliding block 215 along the up-down direction;

[0068] The third sliding block 217 is slidingly installed on the second sliding rail 216;

[0069] The first motor 218 is fixedly installed on the top of the second sliding rail 216, and the output shaft of the first motor 218 is threadedly connected with the third sliding block 217, so that the third sliding block 217 can be driven to slide up and down along the second sliding rail 216 by the first motor 218, thereby adjusting the height of the third sliding block 217;

[0070] The camera mounting seat 219 is rotatably connected with the third sliding block 217;

[0071] The second motor 220 is fixedly installed on one side of the third sliding block 217 and fixedly connected with the camera mounting seat 219, so that the camera mounting seat 219 can be driven to rotate by the second motor 220;

[0072] The industrial camera 22 is fixedly installed on the camera mounting seat 219;

[0073] When different specifications of toothpaste boxes need to be detected, the shooting angle of the industrial camera 22 can be adjusted by the second motor 220, the shooting height of the industrial camera 22 can be adjusted by the first motor 218, and the left-right position of the industrial camera 22 can be adjusted by rotating the knob in the hand.

[0074] Preferably, the camera mounting seat 219 comprises a connecting plate 2191 rotatably connected with the third sliding block 217, a bottom plate 2192 detachably connected with the connecting rod, and a camera mounting plate 2193 slidingly installed on the bottom plate 2192, and two industrial cameras 22 are installed on the camera mounting plate 2193, and the distance between the two industrial cameras 22 can be adjusted.

[0075] Preferably, the rejecting and overturning assembly 4 comprises:

[0076] The guide rail 41 is fixedly installed on the top of the machine base 1 and located above the conveying assembly 3 to avoid interference with the conveying assembly 3;

[0080] A torsion spring is coaxially connected to the swing plate 42, and the end of the torsion spring abuts against the guide rail 41.

[0081] When the third motor 43 rotates clockwise, it drives the swing plate 42 to rotate clockwise. Since the swing plate 42 contacts the guide rail 41 during clockwise rotation, it slides along the guide rail 41. During this sliding process, the defective products move towards the recycling box 5. When the third motor 43 rotates counterclockwise, it drives the swing plate 42 to slide in the opposite direction. During this sliding process, the swing plate 42 abuts against the limit block 44, preventing it from sliding further. It then rotates counterclockwise, causing the qualified toothpaste boxes to flip over. When the third motor 43 stops working, the torsion spring resets the swing plate 42. Because there are toothpaste boxes on the swing plate 42, even if the swing plate 42 does not contact the guide rail 41 during clockwise rotation, it does not affect its sliding.

[0082] Preferably, the swing plate 42 is composed of a first L-shaped plate 421, a second L-shaped plate 422, and a rotating shaft 423 connecting the first L-shaped plate 421 and the second L-shaped plate 422; the length of the second L-shaped plate 422 is greater than that of the first L-shaped plate 421; when the rejection flipping component 4 is pushed out, the second L-shaped plate 422 separates from the conveying component 3 and rotates along the rotating shaft 423, causing the defective products to slide into the recycling box 5.

[0083] Preferably, an infrared beam detector is also installed on the top of the machine 1. The infrared beam detector is positioned opposite to the rejection flipping component 4 and is used to trigger the rejection flipping component 4 to operate when a toothpaste box is detected.

[0084] Preferably, a control box 6 is provided on one side of the machine 1. The control box 6 is equipped with a display 7 and physical buttons 8. The display 7 is used to display detection data, and the physical buttons 8 are used for manual control.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
