Description

Technical Field

[0001] This utility model relates to the technical field of light inspection conveying devices, and in particular to an auxiliary device for light inspection conveying of soft bags. Background Technology

[0002] Transparent or semi-transparent flexible bags require quality inspection during production. The most commonly used method is light inspection, which uses high-speed cameras, sensors, and other imaging equipment to collect images of the flexible bags under specific lighting conditions. Quality inspection includes foreign object detection (checking for visible foreign objects such as glass shards, fibers, white spots, and white patches) and appearance inspection (checking for appearance defects such as cracks, damage, and poor sealing).

[0003] In existing technologies, soft bag light inspection conveying devices generally use clamps to hold the opening of the soft bag while simultaneously performing light inspection. However, during the light inspection process, there is a problem that the light source is blocked at the opening of the soft bag by the clamping tool, resulting in inaccurate inspection results. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for conveying soft bags for light inspection without obstructing the light source, so as to solve the problems mentioned in the background art.

[0006] Furthermore, it also includes a correction component, which includes a drive unit and a correction arm. One end of the drive unit is movably in contact with the correction arm, which is located above the transparent tray. The other end of the drive unit is movably controlling the movement of the correction arm.

[0007] Specifically, the driving component includes a main correction roller, a push plate, a slide rail, and a slider. The main correction roller is fixedly mounted on one end of the push plate, and the other end of the push plate is movably in contact with the correction assembly. The slide rail is fixedly mounted on a plate, and the top surface of the slider is fixedly connected to the bottom of the push plate. The bottom surface of the slider is movably mounted on the slide rail. When the main correction roller drives the slider to move along the slide rail, the main correction roller drives the push plate to touch and squeeze the correction arm to move.

[0008] Specifically, the correction arm includes a correction sub-wheel, a connecting part, and a clamping arm. One end of the connecting part is connected to the correction sub-wheel, and the other end of the connecting part is connected to the clamping arm. The push plate is movably in contact with the correction sub-wheel, and the correction sub-wheel drives the connecting part and the clamping arm to move together.

[0009] Specifically, the correction arm further includes an elastic element, which includes a first connector and a second connector. The correction arm includes two correction sub-wheels, two connecting parts, and two clamping arms. One correction sub-wheel, one connecting part, and one clamping arm form the left arm, and the other correction sub-wheel, another connecting part, and another clamping arm form the right arm. The first connector of the elastic element hooks onto the connecting part of the left arm, and the second connector of the elastic element hooks onto the connecting part of the right arm. The elastic element deforms as the connecting parts of the left and right arms move.

[0010] Specifically, each of the two connecting parts is provided with a mounting post, the first connecting head of the elastic element hooks onto the mounting post connecting the left arm, and the second connecting head of the elastic element hooks onto the mounting post connecting the right arm.

[0011] Specifically, the connecting part includes a mounting arm, an I-shaped component, a U-shaped component, and a reinforcing arm. The I-shaped component and the U-shaped component are arranged parallel to each other. The mounting arm and the reinforcing arm are arranged parallel to each other within the I-shaped component and the U-shaped component. One end of the mounting arm is provided with an opening, and the correction wheel is fixedly installed in the opening.

[0012] The first structure: When the tray assembly includes two transparent trays connected in sequence, the two transparent trays are a first transparent tray and a second transparent tray, the first transparent tray is the driving component, the second transparent tray is the auxiliary component, the bottom of the first transparent tray is provided with a mounting plate, the first transparent tray and the second transparent tray are connected by a rotating shaft, the rotating shaft is located at one end of the second transparent tray, and the flipping roller is located at the other end of the second transparent tray.

Soft bags fall directly onto the transparent trays. The transparent trays, acting as the active component, are driven by the rotating rollers, which in turn cause the transparent trays and the soft bags on them to swing slowly. This facilitates image acquisition of the tube opening and bag body positions by the imaging equipment. Since no clamping tools are used to hold the tube opening, the light source is not obstructed, thus solving the problem of inaccurate detection results caused by light source obstruction. Furthermore, because no clamping tools are needed, this auxiliary device for light inspection of soft bags is suitable for soft bags of different shapes, including those with one tube opening and those with two tube openings.

[0017] Example 1

[0018] The following is a structural description of the auxiliary device in conjunction with the light inspection conveyor: This utility model provides an auxiliary device for conveying soft bags for light inspection, which is connected to a rotary conveyor 1, as shown in the reference. Figure 5 The rotary conveyor 1 includes a frame 11, a chain 12, a drive wheel 13, a guide rail 141, and a correction rail 142. The drive wheel 13 and the chain 12 are both located inside the frame 1. The drive wheel 13 is engaged with the chain 12. The guide rail 141 is located on the outer periphery of the frame 11 and is also located on the periphery of the chain 12. A connecting rod is provided between the guide rail 141 and the frame 1 for fixation. The correction rail 142 is located on the top of the frame 1.

[0019] Please refer to Figures 1-4 The auxiliary devices include: The tray assembly 2 includes two transparent trays 21 connected in sequence. The transparent trays 21 allow a detection light source (such as backlight) to evenly illuminate the bottom of the soft bag through the trays, improving the recognition rate of defects such as foreign objects and black spots. The two transparent trays 21 are a first transparent tray 211 and a second transparent tray 212. The bottom of the first transparent tray 211 is provided with a mounting plate 23, which is connected to the rotary conveyor 1, specifically to the chain 12 on the rotary conveyor 1. Thus, the first transparent tray 211 is the driving component. The first transparent tray 211 and the second transparent tray 212 are connected by a rotating shaft 22, which is located at one end of the second transparent tray 212. No clamps are used, avoiding clamps from obstructing the view and making it easier to completely inspect the outer surface and interface of the soft bag. A flip roller 3 is located at the other end of the second transparent tray 212. The flip roller 3 is movably installed in the guide rail 141. The flip roller 3 is used to drive the second transparent tray 212 to move, and changes the angle between the first transparent tray 211 and the second transparent tray 212 as the trajectory of the guide rail 141 changes.

[0020] During the light inspection, the soft bag is placed on the transparent tray 21. The drive wheel 13 of the rotary conveyor 1 drives the chain 12 on it to move, causing one end of the first transparent tray 211 and the second transparent tray 212 to move together. The other end of the second transparent tray 212 moves with the guide rail 141, thereby changing the angle between the first transparent tray 211 and the second transparent tray 212. (Refer to...) Figure 5 The angle between the first transparent tray 211 and the second transparent tray 212 ranges from 95 degrees to 180 degrees, allowing the soft bag to change from a vertical to a horizontal position, or vice versa. When the soft bag is laid flat (especially horizontally), the internal liquid distribution is more uniform, making it easier to detect sediment, foreign objects, or poorly sealed areas. Certain defects (such as bag opening seals or foreign objects at the top) are easier to observe in the vertical position. Furthermore, the entire process does not obstruct the light source, aiding in light inspection and enabling the imaging equipment to acquire clearer images of the soft bag, improving detection coverage and accuracy. Since the soft bag is placed directly on the transparent tray, it is not subject to mechanical clamping forces, significantly reducing the risk of bag breakage, deformation, and contamination. This also simplifies the equipment structure and reduces manufacturing and maintenance costs. Additionally, the transparent tray 21 is made of a flat, smooth material (such as glass or transparent plastic), making it easier to clean and disinfect, meeting GMP and other clean production requirements. Moreover, because it does not rely on specific clamps for positioning, it can adapt to soft bag products of different sizes, shapes, and weights, resulting in greater flexible production capabilities.

[0021] Reference Figure 2 The first transparent tray 211 has openings 24 on both sides of its end, and the second transparent tray 212 has openings 24 on both sides of its head. The pivot 22 is a screw, and there are two screws. The first screw is inserted into the opening 24 on the left side of the first transparent tray 211 and the second transparent tray 212, and the second screw is inserted into the opening 24 on the right side of the first transparent tray 211 and the second transparent tray 212, thereby completing the connection of the pivot 22 between the first transparent tray 211 and the second transparent tray 212.

[0022] To prevent the soft bag from being tilted on the transparent tray 21, a correction component 4 is also designed, the specific structure of which is as follows: The correction assembly 4 includes a drive member 41 and a correction arm 42. The drive member 41 is located between the correction track 142 and the correction arm 42. The correction arm 42 is located above the transparent support plate 21. Specifically, the correction arm 42 is correspondingly arranged on both sides of the transparent support plate 21. The correction track 142 can move the correction arm 42 by squeezing the drive member 41, i.e., applying force to the drive member 41. Correction can be achieved in several ways. The first method is: correction hand. Arm 42 includes a left clamping arm and a right clamping arm. The left and right clamping arms move closer to each other or further apart in the horizontal direction. When they move closer, they clamp the soft bag and straighten it. The second type: the correction arm 42 includes a left clamping arm and a right clamping arm. The left and right clamping arms tilt to the left / right at the same time and then tilt to the right / left to reset, straightening the soft bag. The third type: the correction arm 42 moves only the left or right clamping arm in the horizontal direction. The soft bag is pushed towards the fixed arm by one side clamping arm 423, straightening the soft bag.

[0023] The following explanation will take the first type of correction arm 42, which includes a left clamping arm and a right clamping arm that can move horizontally, as an example: The driving component 41 includes a main correction roller 411, a push plate 412, a slide rail 413, and a slider 414. The main correction roller 411 is fixedly mounted on one end of the push plate 412 and is movable along the correction track 142. The other end of the push plate 412 is located on the side of the correction assembly 4. The slide rail 413 is fixedly mounted above the rotary conveyor 1. The top surface of the slider 414 is fixedly connected to the bottom of the push plate 412. Figure 5 The slide rail 413 is set at a 90-degree angle to the correction track. The bottom surface of the slider 414 is movably set on the slide rail 413. When the correction track 142 squeezes the correction main roller 411, it drives the slider 414 to move along the slide rail 413, and then the other end of the push plate 412 touches and squeezes the correction arm 42.

[0024] The correction arm 42 includes a correction sub-wheel 421, a connecting part 422, and a clamping arm 423. One end of the connecting part 422 is connected to the correction sub-wheel 421, and the other end of the connecting part 422 is connected to the clamping arm 423. When the push plate 412 movably contacts the correction sub-wheel 421, the correction sub-wheel 421 drives the connecting part 422 and the clamping arm 423 to move together.

[0025] The correction arm 42 also includes an elastic element 424, which can be a spring or a sheet. The elastic element 424 includes a first connector 4241 and a second connector 4242. The correction arm 42 includes two correction sub-wheels 421, two connecting parts 422, and two clamping arms 423. One correction sub-wheel 421, one connecting part 422, and one clamping arm 423 form the left arm, and the other correction sub-wheel 421, another connecting part 422, and another clamping arm 423 form the right arm. The first connector 4241 of the elastic element 424 hooks onto the connecting part 422 of the left arm, and the second connector 4242 of the elastic element 424 hooks onto the connecting part 422 of the right arm. The elastic element 424 deforms as the connecting parts 422 of the left and right arms move.

[0026] Both connecting parts 422 are provided with a mounting post 425. The first connecting head 4241 of the elastic member 424 hooks onto the mounting post 425 of the left arm, and the second connecting head 4242 of the elastic member 424 hooks onto the mounting post 425 of the right arm. The connecting part 422 includes a mounting arm 4221, an I-shaped member 4222, a U-shaped member 4223, and a reinforcing arm 4224. The I-shaped member 4222 and the U-shaped member 4223 are arranged parallel to each other. The mounting arm 4221 and the reinforcing arm 4224 are arranged parallel to each other within the I-shaped member 4222 and the U-shaped member 4223. One end of the mounting arm 4221 is provided with an opening 42211, and the correction wheel 421 is fixedly installed in the opening 42211.

[0027] A baffle 5 is provided on the second transparent tray 212 equipped with a flipping roller 3. The baffle 5 is located at the bottom edge of the second transparent tray 212. When the transparent tray 212 is in a vertical state, the baffle 5 can block the soft bag and prevent the baffle 5 from slipping.

[0028] When the main correction roller 411 touches the correction track 142, the main correction roller 411 presses down, and the slider 414 and push plate 412 move vertically along the slide rail 413. The contact end of the push plate 412 with the correction auxiliary roller 421 is an inverted trapezoidal shape. The two correction auxiliary rollers 421 are squeezed apart by the inclined side of the inverted trapezoid. As the mounting arm 4221 retracts inward, the left and right arms move closer to each other and clamp in a clamping state with the clamping arm 423, thus straightening the soft bag. When the main correction roller 411 leaves the correction track, the main correction roller 411, slider 414, and push plate 412 move upward, the elastic element 424 returns to its original state, and drives the correction auxiliary roller 421 and the clamping arm 423 to move closer to each other. As the mounting arm 4221 opens outward, the soft bag is released, and the left and right arms are reset, that is, the vertical direction movement is converted into the horizontal direction movement, or the Y-axis movement is converted into the X-axis movement.

[0029] When the correction assembly 4 is designed as the third type of correction arm 42, with only the left or right clamping arm moving horizontally, the drive unit 41 and the correction arm 42 can be integrated into one unit, omitting the correction auxiliary wheel 421. The push plate 412 directly connects to the connecting part 422, and there is only one clamping arm 423. The push plate 412, slide rail 413, and slider 414 are designed horizontally. One end of the elastic element 424 is connected to the connecting part 422, and the other end is connected to the slide rail 413. When the main correction roller 411 touches the correction track, it drives the push plate 412, slider 414, connecting part 422, and clamping arm 423 to move left or right together. When the main correction roller 411 leaves the correction track, the elastic element 424 returns to its original position, driving the push plate 412, slider 414, connecting part 422, and clamping arm 423 to move towards the other stationary clamping arm 423, providing a patting force to the soft bag and thus correcting its orientation.

[0030] Example 2

[0031] The difference from Embodiment 1 is that it has three transparent trays 21, but the other structures are the same. The structure and shape of the three transparent trays 21 will be described below.

[0032] Please refer to Figure 6 The auxiliary devices include: The pallet assembly 2 includes three transparent pallets 21, namely a first transparent pallet 211, a second transparent pallet 212, and a third transparent pallet 213. The bottom of the first transparent pallet 211 is provided with a mounting plate 23, which is connected to the chain 12 of the rotary conveyor 1. The first transparent pallet 211 and the second transparent pallet 212, and the second transparent pallet 212 and the third transparent pallet 213 are connected by a rotating shaft 22. The rotating shaft 22 is located at one end of the third transparent pallet 213, and both ends of the second transparent pallet 212 are connected to the rotating shaft 22. A flipping roller 3 is located at the other end of the third transparent tray 213. The flipping roller 3 is movably installed in the guide rail 141. The flipping roller 3 is used to drive the third transparent tray 213 to move, and the angle between the second transparent tray 212 and the third transparent tray 213 changes with the trajectory of the guide rail 141.

[0033] During the light inspection, the soft bag is placed on the transparent tray 21. The drive wheel of the rotary conveyor 1 drives the chain on it to move, causing the first transparent tray 211, the second transparent tray 212, and the third transparent tray 213 to move together. The other end of the third transparent tray 213, which is equipped with a turning roller 3, changes along the trajectory of the guide rail 141, causing the angle between the second transparent tray 212 and the third transparent tray 213 to change. Similarly, the angle between the second transparent tray 212 and the third transparent tray 213 varies from 95 degrees to 180 degrees, so that the soft bag can change from a vertical position to a horizontal position, or vice versa. When placed vertically (especially horizontally), the internal liquid distribution is more uniform, making it easier to detect sediment, foreign objects, or poorly sealed areas. Certain defects (such as bag opening seals or foreign objects at the top) are easier to observe in a vertical position. Furthermore, the entire process does not obstruct the light source, aiding in light inspection and allowing the imaging equipment to acquire clearer images of the soft bags, improving detection coverage and accuracy. The soft bags are placed directly on the transparent tray, free from mechanical clamping forces, significantly reducing the risk of bag breakage, deformation, and contamination. This also simplifies the equipment structure, reducing manufacturing and maintenance costs. Additionally, the transparent tray 21, made of a flat, smooth material (such as glass or transparent plastic), is easier to clean and disinfect, meeting GMP and other clean production requirements. Moreover, because it does not rely on specific clamps for positioning, it can adapt to soft bag products of different sizes, shapes, and weights, resulting in greater flexible production capabilities.

[0034] It is worth noting that the light source device and the imaging device can be set one above the other on the transparent tray 21.

[0035] Before light inspection, soft bags are transported to the auxiliary device using grippers; after light inspection, qualified or unqualified products are picked up from the auxiliary device by grippers for sorting.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
