Description

Technical Field

[0001] This utility model relates to the field of toothpaste testing technology, specifically an image acquisition device for toothpaste appearance inspection. Background Technology

[0002] With societal development, daily chemical companies are increasingly focusing on improving efficiency, increasing profits, and building brands. While high-speed filling equipment on toothpaste production lines enhances production efficiency, it also places higher demands on quality inspection during the toothpaste filling process. The filling quality of toothpaste directly impacts the brand image of toothpaste manufacturers. How to reliably and quickly detect appearance defects in toothpaste after sealing on high-speed filling equipment has become a pressing issue for many toothpaste manufacturers.

[0003] With the development of machine vision technology, online toothpaste appearance inspection equipment based on machine vision technology is increasingly being used in toothpaste production lines, significantly reducing the amount of toothpaste with appearance defects entering the market. In existing technologies, toothpaste appearance inspection equipment based on machine vision technology acquires images of the toothpaste's appearance using industrial cameras. The acquired images are then sent to an image processing unit for feature extraction to achieve quality control and defect detection. However, existing industrial cameras for toothpaste appearance inspection can only acquire images of one side of the toothpaste, leading to errors in the inspection results, which urgently needs improvement. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing toothpaste appearance inspection image acquisition devices can only acquire images of one side of the toothpaste, resulting in errors in the inspection results.

[0005] To solve the above problems, the technical solution of this utility model is: an image acquisition device for toothpaste appearance inspection, including a frame, two conveyor belts installed inside the frame, and an image acquisition component between the two conveyor belts;

[0006] The image acquisition component includes a protective box installed inside the frame. A lower detection camera is installed at the bottom of the protective box, and a transparent glass is installed at the top. An inverted L-shaped fixing frame is installed at the rear end of the frame. An upper detection camera is installed at the top of the fixing frame, directly above the lower detection camera. A pushing component for pushing toothpaste onto the transparent glass is installed at the front end of the frame.

[0007] Furthermore, auxiliary plates are symmetrically fixed to the upper parts of both sides of the protective box, and the upper surfaces of the auxiliary plates, transparent glass and conveyor belt are flush.

[0008] Furthermore, two limiting plates are symmetrically installed on the top of the auxiliary plate, and the front end of the limiting plate is connected to a guide plate extending above the conveyor belt.

[0009] Furthermore, supplementary lights are symmetrically installed on both sides of the lower detection camera inside the protective box.

[0010] Furthermore, the pushing component includes a fixed plate installed on the upper front end of the frame, a KK module installed on the side of the fixed plate, an L-shaped support plate installed at the output end of the KK module, an electric push rod installed at the top of one end of the support plate, a crossbar installed at the output end of the electric push rod, and a push plate fixed to the bottom of the crossbar.

[0011] The advantages of this invention compared to existing technologies are as follows: This invention can simultaneously acquire images of the upper and lower surfaces of the toothpaste using an upper detection camera and a lower detection camera. Combined with two conveyor belts and a pushing component, it can achieve continuous detection of toothpaste, thus improving the practicality of the device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, an image acquisition device for toothpaste appearance inspection includes a frame 1, two conveyor belts 2 are installed inside the frame 1, and an image acquisition component is provided between the two conveyor belts 2.

[0019] The image acquisition component includes a protective box 3 installed inside the frame 1. A lower detection camera 4 is installed at the bottom inside the protective box 3, and a transparent glass 5 is installed at the top inside. Auxiliary plates 8 are symmetrically fixed to the upper parts of both sides of the protective box 3. The auxiliary plates 8, the transparent glass 5 and the upper surface of the conveyor belt 2 are flush. Two limiting plates 9 are symmetrically installed on the top of the auxiliary plates 8. The front end of the limiting plates 9 is connected to a guide plate 10 extending above the conveyor belt 2. Fill lights 11 are symmetrically installed on both sides of the lower detection camera 4 in the lower part of the protective box 3.

[0020] An inverted L-shaped mounting bracket 6 is installed at the rear end of the frame 1. An upper detection camera 7 is installed inside the mounting bracket 6, directly above the lower detection camera 4.

[0021] When the toothpaste moves from the conveyor belt 2 to above the transparent glass 5, the lower detection camera 4 can capture images of the lower surface of the toothpaste, and the upper detection camera 7 can capture images of the upper surface of the toothpaste, thus realizing double-sided image acquisition of the toothpaste, which is more practical.

[0022] The front end of the frame 1 is equipped with a push assembly for pushing toothpaste onto the transparent glass 5. The push assembly includes a fixed plate 12 installed on the upper part of the front end of the frame 1. A KK module 13 is installed on the side of the fixed plate 12. An L-shaped support plate 14 is installed at the output end of the KK module 13. An electric push rod 15 is installed at the top of one end of the support plate 14. A crossbar 16 is installed at the output end of the electric push rod 15. A push plate 17 is fixedly connected to the bottom of the crossbar 16.

[0023] The electric push rod 15 retracts, causing the push plate 17 to descend and be positioned on one side of the toothpaste. The KK module 13 drives the electric push rod 17 to move via the support plate 14, thereby adjusting the position of the push plate 17 and thus enabling the toothpaste to be pushed.

[0024] In practical use, the toothpaste can enter between the two limiting plates 9 through the setting of the guide plate 10 and the limiting plate 9. The electric push rod 15 retracts, causing the push plate 17 to drop and be located on one side of the toothpaste. The KK module 13 drives the push plate 17 to move, which can push the toothpaste to the center of the transparent glass 5. At this time, the KK module 13 drives the push plate 17 to move away from the toothpaste. At this time, the upper detection camera 7 and the lower detection camera 4 can simultaneously collect images of the upper and lower surfaces of the toothpaste. After the acquisition is completed, the KK module 13 drives the push plate 17 to move and push the toothpaste onto the next conveyor belt 2. The toothpaste is then transported to the sorting station via the conveyor belt 2.
