Description

Technical Field

[0001] This utility model relates to the field of label detection technology, specifically to an automatic product label detection device. Background Technology

[0002] Labels are a symbol of product identity and help to quickly identify products and understand their basic information. Therefore, labels on products should be kept clear and accurate.

[0003] In related technologies, a solution for an automatic product label detection device (announcement number CN216901923U) was found. First, the label is placed in front of the spotlight. Then, the first motor is started. At the same time, the first motor drives the sliding rod to slide on the inner wall of the elongated hole. Then, the rotating block rotates around the rotating shaft. The rotating block drives the spotlight to irradiate the damaged label. If there is damage, the light will shine on the surface of the receiver. The receiver will transmit the signal to the alarm. At this time, the staff can more easily and accurately find the damaged label.

[0004] However, the above solution uses an assembly line to transport products. If the products are not placed correctly during the transportation process, it is easy to cause problems such as mis-detection, incorrect detection, and missed detection of labels. This may require rework of the products, increasing additional time and costs and reducing detection efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic product label detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic product label detection device, including a conveyor, an inspection box installed above the conveyor, and adjusters installed on both the left and right sides inside the inspection box. A CCD camera is installed on the adjuster. By using the adjuster, the height of the CCD camera can be changed to facilitate the detection of different products.

[0007] Support bars are installed on the left and right sides of the conveyor. Insertion blocks are installed on the support bars. Lifting seats are installed in the insertion blocks. Sliding rods are inserted into the lifting seats. Guide bars are rotatably installed at the ends of the sliding rods. The two guide bars guide the forward direction of the products, which facilitates the limiting and guidance of products of different sizes and improves the accuracy of CCD camera detection.

[0008] Furthermore, a pusher is installed on the right side of the conveyor via a bracket assembly, and a guide hopper corresponding to the pusher is installed on the left side of the conveyor. When the product label is unqualified, the pusher pushes the product off the conveyor and automatically rejects it, eliminating the need for manual rejection.

[0009] Furthermore, the guide strip surface is equipped with several guide wheels, which can reduce friction on the product and maintain the integrity of the product surface.

[0010] Furthermore, a cylinder is connected to the lower surface of the lifting seat, and the cylinder slides into a quick-connect fitting. A first handle screw is screwed onto the side of the quick-connect fitting to abut against the cylinder. A second handle screw is screwed onto the upper surface of the lifting seat to abut against the sliding rod. Tightening the first and second handle screws can adjust the height and translation of the guide bar, making operation convenient.

[0011] Furthermore, the adjuster includes a column, on which a mounting base is sleeved. A third handle screw is screwed onto the mounting base to abut against the column. The CCD camera is mounted on the mounting base, and turning the third handle screw can adjust the height of the CCD camera to facilitate alignment of the CCD camera with the label.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the product to be inspected is transported to the conveyor, the conveyor transports the product between two guide bars, the guide bars keep the product moving stably, and when the product passes the CCD camera, the label can be better aligned with the CCD camera, improving the CCD camera's shooting accuracy of the label, ensuring that the product label can be inspected with high precision, continuity and high speed, suitable for products of different sizes, and products with unqualified labels are pushed into the guide hopper by the dual-axis cylinder, which can automatically reject products with unqualified labels.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-4 This utility model provides a technical solution: an automatic product label detection device, including a conveyor 5, which picks up products and delivers them to the location of a CCD camera 13. An inspection box 1 is installed above the conveyor, and adjusters are installed on both the left and right sides inside the inspection box 1. A CCD camera 13 is installed on the adjuster, and the CCD camera 13 captures images of the product label to provide images for the detection of the product label.

[0021] Support bars 6 are installed on the left and right sides of the conveyor. Insertion blocks 7 are installed on the support bars 6. Lifting seats 15 are installed in the insertion blocks 7. Sliding rods 18 are inserted into the lifting seats 15. Guide bars 8 are rotatably installed at the ends of the sliding rods 18. The two guide bars 8 guide the forward direction of the product. The sliding rods 18 can be adjusted by lifting, rotating, and translating. Figure 3 and Figure 4 As shown, this allows the guide bar 8 to be adjusted flexibly, and the product is guided by the guide bar 8 and is not easily deviated, making it convenient for the CCD camera 13 to complete the shooting of the note in one go.

[0022] In this embodiment, as Figure 1 As shown, a pusher is installed on the right side of the conveyor via a bracket assembly 2, and a guide hopper 14 corresponding to the pusher is installed on the left side of the conveyor. The pusher includes a dual-axis cylinder 3, and the piston rod of the dual-axis cylinder 3 is connected to a pusher 4. When the product label is unqualified, the conveyor 5 transports the product to the position of the pusher 4, and the dual-axis cylinder 3 controls the pusher 4 to push the product from the conveyor 5 onto the guide hopper 14 and let it slide down.

[0023] In this embodiment, as Figure 3 As shown, several guide wheels 9 are installed on the surface of the guide bar 8. The rotation of the guide wheels 9 can prevent the guide bar 8 from wearing down the product, and the product moves more smoothly with the conveyor 5.

[0024] In this embodiment, as Figure 4As shown, a cylinder 19 is connected to the lower surface of the lifting seat 15, and the cylinder 19 is slidably connected to the plug-in 7. The cylinder 19 can be raised, lowered, and rotated in the plug-in 7. A first handle screw 16 is screwed to the side of the plug-in 7 to abut against the cylinder 19. Turning the first handle screw 16 to separate it from the cylinder 19 can adjust the cylinder 19. A second handle screw 17 is screwed to the upper surface of the lifting seat 15 to abut against the sliding rod 18. Turning the second handle screw 17 to separate it from the sliding rod 18 can move the sliding rod 18 horizontally. The sliding rod 18 drives the guide bar 8 to be adjusted.

[0025] In this embodiment, as Figure 2 As shown, the adjuster includes a column 10, a mounting base 11 is sleeved on the column 10, and a third handle screw 12 is screwed onto the mounting base 11 to abut against the column 10. The CCD camera 13 is installed on the mounting base 11. By turning the third handle screw 12, the height of the mounting base 11 on the column 10 can be changed, thereby changing the height of the CCD camera 13.

[0026] Specifically, during use, the conveyor 5 picks up the product to be inspected, and the spacing between the two guide bars 8 is adjusted according to the size of the product. The conveyor 5 transports the product between the two guide bars 8. When the product passes the CCD camera 13, the guide bars 8 can prevent the product from shifting, ensuring that the label on the product can be more accurately aligned with the CCD camera 13. The CCD camera 13 can complete the accurate shooting of the label in one go. Products with qualified labels are transported to the next process by the conveyor 5, while products with unqualified labels are transported to the side of the push bar 4 by the conveyor 5. The dual-axis cylinder 3 pushes the product onto the inclined guide hopper 14 through the push bar 4, realizing the automatic rejection of the product.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
