Description

Technical Field

[0001] The invention belongs to the field of bag delivery machines, in particular to visual inspection equipment for bag delivery machines. Background Art

[0002] At present, the overview of the bag throwing machine is as follows: the bottle blocking cylinder on the bottle feeding track of the bottle conveying mechanism will block the bottle conveyed by the previous equipment at the position of loading desiccant, waiting to be loaded with desiccant, and the bottle mouth is aligned with the shearing mechanism; the stepper motor drives the bag feeding mechanism to pull the desiccant bag out of the desiccant bag rack, the color code sensor detects the desiccant bag and controls the bag length, the scissors cut the desiccant bag and put it into the bottle, the conveyor belt of the bottle conveying mechanism transports the medicine bottle loaded with desiccant to the next equipment, and at the same time, the medicine bottle to be loaded with desiccant is added to the position of loading desiccant bag.

[0003] When using a bag-dropping machine, inspection equipment can be used to inspect unqualified packages. Visual inspection is to use machines instead of human eyes to make measurements and judgments. Visual inspection refers to the use of machine vision products (i.e. image capture devices, divided into CMOS and CCD) to convert the captured target into an image signal, which is transmitted to a dedicated image processing system and converted into a digital signal based on pixel distribution, brightness, color and other information. The image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging. It has immeasurable value in the function of detecting defects and preventing defective products from being delivered to consumers. When using inspection equipment in a bag-dropping machine, deep learning AI algorithms will be added to the self-programming of the inspection equipment to enable it to sort out the inspected packages according to requirements to see if they meet the standards.

[0004] However, during the use of traditional detection equipment, it was found that the above technology has at least the following problems:

[0005] 1. In traditional inspection equipment, the camera assembly usually needs to be connected to the corresponding installation position with screws, and then the corresponding wires are pulled out and connected to the interface position on the camera assembly. When the wires are pulled out, they need to be sorted out. The overall operation process is time-consuming and laborious.

[0006] 2. In traditional inspection equipment, when using inspection cameras for inspection and processing, if unqualified material packages are detected, the traditional operation method is to control the entire package delivery machine to stop working, and then manually cut and remove the corresponding unqualified material packages, thereby reducing the work efficiency of the entire package delivery process.

[0035] The embodiments of the present application solve the problems in the prior art by providing a visual inspection device for a bag delivery machine.

[0036] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0037] Embodiment 1:

[0038] This embodiment provides the specific structure of the entire detection device, such as Figure 1-Figure 6 As shown, a visual inspection device for a bag delivery machine includes a detection box 3 and a guide frame 4 arranged in the detection box 3. The detection box 3 is installed on a frame 1, and a transmission roller 2 is installed on the top of the frame 1. The bag to be inspected is transmitted on the transmission roller 2 and passes through the guide frame 4.

[0039] In specific application scenarios, the series-connected material packages are Figure 1 The material is wound onto the surface of the middle transmission roller 2 , and then enters through the brush opening 7 above the detection box 3 , passes through the guide frame 4 , and finally is discharged from the brush opening 7 below the detection box 3 .

[0040] The front side of the detection box 3 is detachably equipped with a camera assembly, the back side is hinged with a box door 14, and the inner wall of the box door 14 is embedded with a light board 15. The inner wall of the detection box 3 is installed with a pushing assembly for pushing unqualified material packages, and an infrared cutter 13 is installed on the material package pushing track in the detection box 3.

[0041] After the camera component detects an unqualified material package, the pushing component pushes the unqualified material package, and after passing through the infrared cutter 13 and being cut by the infrared cutter 13, a single unqualified material package is pushed into the surface of the box door 14 by the suction cup mouth 12. After the box door 14 is pushed open, the single unqualified material package falls into the storage box 5.

[0042] In some examples, the guide frame 4 includes two sets of parallel distributed support rods 41 , and two sets of guide rollers 42 are installed on each of the support rods 41 . The material package to be detected passes through the area formed between the two sets of guide rollers 42 .

[0043] In some examples, a brush opening 7 is provided on both the upper and lower surfaces of the detection box 3, and a plurality of brush bristles are arranged in an alternating manner on the inner wall of the brush opening 7. After the material package to be detected passes through the brush opening 7, the material package can be preliminarily positioned, and the surface of the material package can also be cleaned;.

[0044] In some examples, the camera assembly includes a mounting plate 8 and a detection camera 9;

[0045] A plate slot 16 is provided on the surface of the detection box 3 for inserting the assembly plate 8 ; the detection camera 9 is rotatably mounted on the surface of the assembly plate 8 , and the camera head of the detection camera 9 is located in the storage box 5 .

[0046] During the installation of the assembly plate 8, after holding the assembly plate 8, insert the assembly plate 8 into the plate slot 16, and then after the contact piece contacts the protruding piece, the camera assembly is connected to the external power supply. At this time, the camera assembly starts working and completes real-time monitoring of the material packages passing through the area between the guide frames 4.

[0047] A notch is provided on the top side of the assembly plate 8, a contact piece is provided in the notch, and a convex piece is provided at a position on the inner wall of the plate slot 16 corresponding to the notch. When the assembly plate 8 is fully inserted into the plate slot 16, the contact piece in the notch contacts with the convex piece, and the camera assembly is electrically connected to the external power supply.

[0048] The above-mentioned detection camera 9 is connected to the assembly plate 8 by setting a bearing. A baffle 10 is welded on the surface of the detection camera 9 at one end inside the detection box 3. The movement trajectory of the baffle 10 coincides with the inner wall of the detection box 3. When installing the detection camera 9, the detection camera 9 is rotated to make the baffle 10 fit the inner wall of the detection box 3, thereby ensuring the stability of the position of the detection camera 9. At the same time, the static friction generated between the baffle 10 and the detection box 3 is also used to ensure that the detection camera 9 does not rotate.

[0049] Embodiment 2:

[0050] This embodiment provides the specific structure of the entire detection device, such as Figure 1-Figure 6 As shown, an alarm light 6 is installed on one side of the outer wall of the detection box 3 close to the box door 14, and the alarm light 6 is connected to the camera assembly by setting a data cable. The alarm light 6 here will automatically turn on and flash only after the detection camera 9 detects unqualified material packages to remind the staff.

[0051] The pushing component includes a pushing cylinder 11 and a suction cup port 12;

[0052] The pushing cylinder 11 is tiltedly located below the camera assembly; the suction cup port 12 is arranged at one end of a piston rod matched with the pushing cylinder 11, and the moving track of the suction cup port 12 coincides with the detection range of the camera assembly.

[0053] In a specific application scenario, the pushing cylinder 11 drives the suction cup mouth 12 to move obliquely upward, and then the suction cup mouth 12 drives the unqualified material packages to move toward the position of the box door 14, and then the unqualified material packages are individually cut by the infrared cutter 13, and then the unqualified material packages at this location are discharged from the opened box door 14, and finally fall into the storage box 5 to complete the collection and processing.

[0054] In some examples, there are two groups of infrared cutters 13, and the spacing between the two groups of infrared cutters 13 matches the length of the material package to be detected. The infrared cutters 13 here use infrared light to complete the cutting process on the edge of the material package.

[0055] By adopting the above technical solution:

[0056] With the help of the detection camera 9 and the light board 15 in the camera assembly, the infrared light source is transmitted through the edge of the material bag to highlight the outline of the filler in the material bag and the edge of the material bag. The deep learning AI algorithm can be used to quickly detect stuck materials, empty bags and whether the loading quantity meets the standards, avoiding subsequent manual operations and automatically discharging unqualified material bags.

[0057] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
