Technical Field

[0001] The present invention relates to the technical field of detection devices, and more particularly to a food processing detection device and a detection method. Background Art

[0002] In the field of automated inspection in the food processing industry, the detection of visual defects and internal foreign matter has become a core component in ensuring food quality and safety. This is particularly true in automated packaging lines for pasta products like buns and dumplings. Post-packaging visual inspection directly determines the efficiency of detecting quality issues such as missing packaging, damaged packaging, and poor seals. Traditional inspection systems typically utilize a fixed inspection table combined with a single conveyor mechanism, which presents limitations when addressing the specialized inspection requirements of post-packaging food.

[0003] Existing inspection platforms are mostly flat, fixed structures. The food being inspected remains fixed during transport, leading to blind spots at the edges of the inspection machine due to internal light source refraction, shadows, or blind angles. For example, when the edge of a food approaches the edge of the inspection machine, industrial cameras or sensors struggle to capture a clear image, leading to missed detection of edge defects in curved or irregularly shaped food, seriously impacting food quality and safety. Summary of the Invention

[0004] The present invention provides a food processing detection device and detection method, which solves the technical problem in the related art that the posture of the food to be detected is fixed during the transportation process, resulting in the edge area being easily refraction of the light source inside the detection machine, shadows or dead angles forming detection blind spots.

[0009] As a further optimization solution of the present invention, the second conveying roller includes a conveying roller body, and the conveying roller body is connected to the internal bearing of the storage platform. The interior of the conveying roller body is annularly provided with multiple groups of piston blocks.

[0010] As a further optimization scheme of the present invention, the interior of the conveying roller body is provided with multiple groups of guide grooves adapted to the piston block, the piston block is slidingly connected to the guide grooves, the interior of the conveying roller body is provided with a cavity, and a spring is installed between the cavity and the piston block.

[0011] As a further optimization scheme of the present invention, multiple groups of the second spline shafts are provided with an air injection mechanism, which injects air into the cavity to push the piston block, causing the spring to produce elastic deformation and the piston block to expand outward under the action of pressure.

[0012] As a further optimization solution of the present invention, the apex position of the expanded piston block is flush with the apex position of the first conveying roller.

[0013] As a further optimization scheme of the present invention, the air injection mechanism includes an air box arranged on the outside of multiple groups of second spline shafts, and an air injection pipe is installed on the air box, multiple groups of annular sliders are installed inside the air box, and annular slide rails are slidably connected to the annular sliders, and the annular slide rails are installed on the second spline shafts. Multiple groups of air inlets are opened on the second spline shafts, and the air inlets are located inside the air box, an air cavity is opened inside the second spline shaft, and multiple groups of air outlets are opened in the middle of the second spline shaft, and the air outlets are connected to the inside of the cavity.

[0014] Another aspect of the present invention discloses a food processing detection method, comprising the following steps:

[0015] S1. The food to be tested is conveyed to the testing table. The height difference between the first conveyor roller and the second conveyor roller is used to automatically stop and position the food in the middle of the testing table.

DETAILED DESCRIPTION

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0031] Example 1: According to the attached Figure 1 To the attached Figure 3 As shown, a food processing detection device includes a frame 100, a detection machine 400 is installed on the frame 100, and a detection platform 500 is installed on the detection machine 400. When the food to be detected is moved above the detection platform 500, the detection machine 400 is used to detect the appearance of the food to be detected and whether there are foreign objects inside. An auxiliary detection unit 600 is provided on the detection platform 500, and the auxiliary detection unit 600 is used to perform auxiliary detection processing when detecting the appearance of the food.

[0032] Specifically, a conveyor belt 300 is provided on the frame 100, and multiple sets of transmission shafts 200 are provided inside the conveyor belt 300. The transmission shafts 200 are connected to the frame 100 by bearings. The transmission shafts 200 rotate to control the conveyor belt 300 to transport the inspection object.

[0033] Among them, first transmission rollers 700 are arranged on both sides of the detection machine 400, and the first transmission rollers 700 are connected to the frame 100 by bearings. Second transmission rollers 800 are symmetrically arranged on the detection machine 400, and the second transmission rollers 800 are connected to the detection machine 400 by bearings. The middle part of the conveyor belt 300 passes through the first transmission roller 700 and the second transmission roller 800 to form a concave state.

[0034] According to the attached Figure 3 To the attached Figure 5 As shown, the auxiliary detection unit 600 includes a storage table 610 arranged on the detection table 500, and multiple groups of first conveying rollers 620 are symmetrically arranged on both sides of the storage table 610, the storage table 610 and the first conveying rollers 620 are connected by bearings, and a swing mechanism 640 is provided on the storage table 610, and the swing mechanism 640 is used to control the storage table 610 to swing back and forth, the first conveying roller 620 is internally slidably connected to the first spline shaft 650, and the second conveying roller 630 is internally provided with a second spline shaft 660, and the first spline shaft 650 and the second spline shaft 660 are connected to the inner wall bearings of the detection machine 400.

[0035] Among them, according to the attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, multiple groups of first spline shafts 650 and second spline shafts 660 are connected via a pulley transmission mechanism 670 , and one group of first spline shafts 650 is connected to the transmission shaft 200 via a sprocket transmission mechanism 900 .

[0036] It should be understood that when the food processing and detection device is in operation, the motor controls the transmission shaft 200 to rotate, so that the conveyor belt 300 conveys the object to be detected. While the conveyor belt 300 is conveying, the transmission shaft 200 and the first spline shaft 650 are connected through the sprocket transmission mechanism 900, driving multiple groups of first spline shafts 650 and second spline shafts 660 to rotate synchronously, thereby controlling the first conveyor roller 620 and the second conveyor roller 630 to rotate.

[0037] That is, when the conveyor belt 300 delivers the food to be inspected to the position of the first conveyor roller 620, the food is conveyed to the inspection table 500 by the first conveyor roller 620, and further inspected by the inspection machine 400. Furthermore, the swing mechanism 640 controls the reciprocating swing of the storage table 610, thereby controlling the displacement of the food to be inspected. This allows the edge of the food to be moved to the middle of the inspection position during the appearance inspection of the food, allowing clear images of the food's appearance near the edge of the inspection machine 400, thereby preventing the inspection from being affected by refraction of the light source within the inspection machine 400, shadows, or blind spots.

[0038] It should be noted that according to the Figure 4 and attached Figure 5 As shown, multiple sets of second conveyor rollers 630 are positioned in the middle of the storage platform 610. The apex height of the first conveyor rollers 620 is greater than that of the second conveyor rollers 630, and the apex position of the second conveyor rollers 630 is lower than the upper surface of the storage platform 610. In this embodiment, when the first conveyor rollers 620 convey the food to be inspected to the middle of the inspection platform 500, the height difference between the first and second conveyor rollers is utilized to automatically stop the food to be inspected due to a change in the supporting surface when the food reaches the middle of the inspection platform. This ensures that the food is fixed in position during inspection and improves inspection accuracy.

[0039] In summary, the swing mechanism drives the table back and forth, periodically moving the edge of the food being inspected to the center of the inspection position. This prevents missed inspections at the edges of the inspection machine due to light source refraction, shadows, or blind spots. Furthermore, the food's posture changes dynamically during the swing process, allowing the inspection equipment to capture multi-dimensional appearance information, such as the top and sides. This overcomes the blind spot issues of traditional static inspections and is particularly suitable for full-surface defect detection of irregularly shaped foods.

[0040] Furthermore, according to the attached Figure 7 , Attachment Figure 8 and attached Figure 9 As shown, the second conveyor roller 630 includes a conveyor roller body 631, and the conveyor roller body 631 is connected to the internal bearing of the storage platform 610. The interior of the conveyor roller body 631 is provided with multiple groups of piston blocks 632 in a ring shape. The interior of the conveyor roller body 631 is provided with multiple groups of guide grooves adapted to the piston blocks 632. The piston blocks 632 are slidably connected to the guide grooves. A cavity is provided inside the conveyor roller body 631, and a spring 633 is installed between the cavity and the piston block 632.

[0041] Among them, according to the attached Figure 7 , Attachment Figure 8 and attached Figure 10 As shown, multiple groups of second spline shafts 660 are provided with gas injection mechanisms 680, which inject gas into the cavity to push the piston block 632, causing the spring 633 to produce elastic deformation, and the piston block 632 expands outward under the action of pressure.

[0042] It should be noted that the apex of the expanded piston block 632 is flush with the apex of the first conveying roller 620 ; and a rubber pad is glued to the outer surface of the piston block 632 .

[0043] When the piston block 632 is pushed outward and expanded, the rubber pad on the piston block 632 contacts the bottom surface of the detection object. The second spline shaft 660 rotates to control the piston block 632 to convey the detection object, so that it enters the conveying area of ​​the first conveyor roller 620, thereby continuing to convey the detected food, thereby facilitating subsequent operations.

[0044] According to the attached Figure 10 As shown, the gas injection mechanism 680 includes an air box 681 arranged on the outside of multiple groups of second spline shafts 660, and an air injection pipe 682 is installed on the air box 681, multiple groups of annular sliders 683 are installed inside the air box 681, and an annular slide rail 684 is slidably connected to the annular slider 683, and the annular slide rail 684 is installed on the second spline shaft 660, and multiple groups of air inlets 685 are provided on the second spline shaft 660, and the air inlets 685 are located inside the air box 681, an air cavity 686 is provided inside the second spline shaft 660, and multiple groups of air outlets 687 are provided in the middle of the second spline shaft 660, and the air outlets 687 are communicated with the inside of the cavity.

[0045] During operation, the gas injection tube 682 is connected to an external gas supply device. When testing is complete, the gas supply device supplies air to the interior of the air box 681. The gas enters the air cavity 686 through the air inlet 685 and is discharged into the cavity through the air outlet 687. This pushes the piston block 632, causing the spring 633 to elastically deform. Under the action of pressure, the piston block 632 expands outward, transporting the test object. By controlling the expansion and contraction of the piston block 632 by air pressure, the second conveyor roller 630 can quickly switch between being below the surface of the storage platform and flush with the first conveyor roller, achieving a seamless connection between the detection and conveying functions.

[0046] According to the attached Figure 6 As shown, the swing mechanism 640 includes a connecting frame 641 installed inside the testing platform 500, and a motor 642 is installed on the connecting frame 641, a wheel 643 is installed on the output shaft of the motor 642, and a protruding rod 644 is installed on the wheel 643, a swing arm 645 is rotatably connected to the connecting frame 641 through a rotating shaft, and a movable groove 646 is provided inside the swing arm 645, and the movable groove 646 is slidably connected to the protruding rod 644, a movable frame 647 is provided inside the testing platform 500, and a traction rod 648 is provided on the movable frame 647, a traction groove 649 is provided on the swing arm 645, and the traction groove 649 and the traction rod 648 are slidably connected, connecting rods 6410 are symmetrically installed on the movable frame 647, and the connecting rod 6410 passes through the testing platform 500 and is fixedly connected to the storage platform 610, and a slot adapted to the connecting rod 6410 is provided on the testing platform 500. The movable frame 647 is slidably connected to a limiting guide rail 6411 , and the limiting guide rail 6411 is fixedly connected to the testing platform 500 .

[0047] It should be noted that when the wheel rotates, the protruding rod slides from bottom to top and then to bottom in the movable groove, forcing the swing arm to swing back and forth around the rotating axis. When the swing arm swings, the traction rod slides horizontally in the traction groove, driving the movable frame to make a straight reciprocating motion in the vertical direction along the limiting guide rail 6411, controlling the storage platform 610 to swing back and forth, thereby facilitating detection.

[0049] S1. The food to be tested is conveyed to the testing table 500. The height difference between the first conveyor roller 620 and the second conveyor roller 630 is used to automatically stop and position the food in the middle of the testing table.

[0050] S2: The swing mechanism 640 drives the object to be inspected to dynamically adjust its posture, and the inspection machine 400 inspects the appearance of the food and foreign matter inside it during the swinging process;

[0051] S3.

[0052] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method.
