Description

Technical Field

[0001] This utility model relates to the field of inkjet printing inspection equipment technology, specifically to an inkjet printing inspection device based on machine vision. Background Technology

[0002] With the ever-increasing demand for quality and rapid production, product coding is becoming increasingly important. The reasons are self-evident: reducing the number of defective products and providing qualified products. Manual product coding inspection is too expensive and implies monotonous, impersonal work. Continuously increasing manufacturing productivity makes manual inspection increasingly impractical. Here, digital image processing technology offers solutions. Currently, identifying coding information on product packaging surfaces, including defects such as font size, character presence, missing strokes, and errors, relies on manual visual inspection. This method is not only inefficient and slow but also inaccurate. The inkjet printing on product surfaces contains information such as production dates and shelf-life. Problems with this printing can easily lead to incorrect food shelf-life readings, misleading consumers and causing significant harm. Furthermore, it can disrupt inventory management and product traceability, hindering production and sales management. Single-function inkjet printers, with their limited functionality, suffer from low pass rates and poor quality, and are now rarely used. Integrated automated inkjet printing and inspection equipment is too expensive, unable to meet the continuous inspection needs of large volumes of products, and has low material handling efficiency, thus presenting certain drawbacks. Therefore, we propose a machine vision-based inkjet printing and inspection device. Utility Model Content

[0003] The purpose of this invention is to provide a machine vision-based inkjet printing inspection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a machine vision-based inkjet printing detection device, comprising a base, a side plate on the top of the base, a top plate hinged inside the side plate, a support block for supporting the top plate inside the side plate, a positioning plate on the side of the side plate, a roller shaft inside the positioning plate, a conveyor belt on the roller shaft, an elastic limiting band on the conveyor belt, an arc-shaped locking block engaged on the inner side of the end of the elastic limiting band, a bracket connected to the top of the arc-shaped locking block, an inkjet printer mounted on the side plate, and a controller and an alarm mounted on the top plate.

[0005] In the above scheme, casters are provided at the bottom of the base.

[0006] In the above scheme, a limiting rod is movably inserted into the side of the side plate, and the end of the limiting rod is inserted into the limiting hole on the side of the top plate.

[0007] In the above scheme, a limit block is provided on the side of the elastic limiting band.

[0008] In the above scheme, the bracket is fixed inside the side plate.

[0009] In the above scheme, a collection frame is provided on the lower side of the end of the conveyor belt.

[0010] In the above scheme, the controller is connected to the power supply via a wire.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This machine vision-based inkjet printing inspection device has a simple and reasonable structural design and strong practicality. By setting a conveyor belt as a conveying mechanism, the equipment to be inspected can quickly pass through the internal space of the side plate and be rapidly and comprehensively scanned by the inkjet printer. The product is scanned when it first passes the inkjet printer and then judged by the controller to determine whether it is correct. By setting an elastic limit band on the conveyor belt as a limiting mechanism, the internal equipment can be constrained to adapt to the positioning requirements of workpieces of different sizes. Under the action of the arc-shaped block, the two elastic limit bands are opened, allowing the equipment confined inside the elastic limit band to fall into the collection frame, further ensuring the efficiency of the equipment inspection process. The inkjet printer is connected to the controller, and the controller is connected to the alarm through a signal line, which can better increase the monitoring of the product qualification rate. The alarm can prompt the operator to handle defective products in a timely manner, making the operation more convenient and efficient. It has the advantages of being easy and quick to use, having low operating costs, comprehensive functions, and greatly improving the product qualification rate. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a machine vision-based inkjet printing detection device, including a base 1, a side plate 12 on the top of the base 1, a top plate 13 hinged inside the side plate 12, a support block 14 for supporting the top plate 13 inside the side plate 12, a positioning plate 16 on the side of the side plate 12, a roller 17 inside the positioning plate 16, a conveyor belt 18 on the roller 17, an elastic limiting band 19 on the conveyor belt 18, an arc-shaped locking block 21 engaged at the inner end of the elastic limiting band 19, a bracket 22 connected to the top of the arc-shaped locking block 21, an inkjet printer 24 mounted on the side plate 12, and a controller 25 and an alarm 26 mounted on the top plate 13. Specifically, a motor is connected to the end of the roller 17, driving the roller 17 to rotate, thereby driving the conveyor belt 18 to rotate.

[0018] In the above scheme, the base 1 is equipped with casters 11 at its bottom. The design of the casters 11 makes it easy to move the device.

[0019] In the above scheme, a limiting rod 15 is movably inserted into the side of the side plate 12, and the end of the limiting rod 15 is inserted into the limiting hole on the side of the top plate 13.

[0020] In the above scheme, a limit block 2 is provided on the side of the elastic limiting band 19. By setting the conveyor belt 18 as a conveying mechanism, the device to be tested can quickly pass through the internal space of the side plate 12 and be quickly and comprehensively scanned by the inkjet printer 24. The product is scanned when it first passes the inkjet printer 24 and then the controller 25 judges whether it is correct. The controller 25 issues a corresponding command to the alarm 26.

[0021] In the above scheme, the bracket 22 is fixed inside the side plate 12.

[0022] In the above scheme, a collection frame 23 is provided on the lower side of the end of the conveyor belt 18. By setting an elastic limiting band 19 on the conveyor belt 18 as a limiting mechanism, the internal equipment can be limited and constrained to adapt to the positioning requirements of workpieces of different sizes. Under the action of the arc-shaped locking block 21, the two elastic limiting bands 19 are opened, so that the equipment restricted inside the elastic limiting band 19 can fall into the collection frame 23, further ensuring the efficiency of the equipment inspection process.

[0023] In the above scheme, the controller 25 is connected to the power supply via a wire. The inkjet printer 24 is connected to the controller 25, and the controller 25 is connected to the alarm 26 via a signal line. This improves the monitoring of product qualification rate, and the alarm 26 can prompt operators to handle defective products in a timely manner. This makes operation more convenient and efficient, and has the advantages of being easy and quick to use, having low operating costs, comprehensive functions, and greatly improving the product qualification rate.

[0024] Working principle:

[0025] This machine vision-based inkjet printing inspection device places the device to be inspected within the elastic limiting band 19 during operation. The conveyor belt 18, with its own drive mechanism, propels the device into the side panel 12 for inspection by the inkjet printer 24. If the inkjet printing is normal, the controller 25 receives feedback and enables the device to operate normally. The arc-shaped locking block 21 expands the elastic limiting band 19 to both sides, allowing the device to disengage and fall into the collection box 23. When the inkjet printer 24 detects a problem with the inkjet printing, the controller 25 commands the drive mechanism of the conveyor belt 18 to stop, triggering an alarm 26. The user removes the limiting rod 15 and opens the top panel 13, allowing them to remove the defective device for further processing. This achieves rapid inkjet printing inspection of the device.
