Description

Technical Field

[0001] This utility model belongs to the field of cotton swab production and packaging technology, and in particular relates to a rotatable cotton swab visual inspection device and its conveying device. Background Technology

[0002] In the cotton swab production process, small sticks (swab sticks) need to be conveyed, and cotton is wrapped around one or both ends of the sticks. If the ends of the sticks are not filled with cotton, or if the shape, amount, or fullness of the cotton does not meet the requirements, the cotton swab is considered defective. During the conveying process, the sticks on the conveying toothed disc are arranged in a continuous manner. Defective products need to be identified by images, and then rejected by a rejection mechanism. For example, the utility model patent with publication number CN219448379U, entitled "Swab Conveying Device with Rejection Structure," discloses the specific structure of the cotton swab rejection device. However, in the prior art, the finished product vision mechanism can only detect the image above the top of the cotton swab on the conveying toothed disc, and cannot collect image data of the bottom and sides of the cotton swab. Therefore, when the bottom of the cotton swab is defective, it cannot be detected by the finished product vision mechanism, resulting in a high defect rate and affecting the production quality of the cotton swabs. Utility Model Content

[0003] To address the technical problem that existing cotton swab removal and conveying devices can only collect image data from the surface of the cotton swab and cannot collect image data from other positions, this invention provides a rotatable cotton swab visual inspection device. This device includes a vision mechanism for inspecting the cotton swab, and a cotton swab flipping mechanism installed below the vision mechanism. The cotton swab flipping mechanism includes a support plate, and a first rotating shaft and a second rotating shaft arranged parallel and spaced apart are provided above the support plate. The first rotating shaft and the second rotating shaft are rotatably mounted on the top of the support plate via bearing assemblies. Two first pulleys are fixed on the first rotating shaft, spaced apart. Two second pulleys are fixed on the second rotating shaft, corresponding one-to-one with the first pulleys. A rubber belt is tensioned between each of the corresponding first pulleys and the second pulley. The cotton swab flipping mechanism also includes a drive mechanism for driving the first or second rotating shaft to rotate. The rubber belt abuts against the cotton swab located on the conveying device, and the rubber belt moves in the opposite direction to the conveying device. By setting up a cotton swab flipping mechanism, the drive mechanism drives the first or second rotating shaft to rotate, thereby enabling the rubber belt to move the cotton swabs located on the rubber belt in the opposite direction to the cotton swab conveying direction. Under the action of the conveying device and the rubber belt, the cotton swabs are rotated, which allows the vision mechanism to collect image signals from various angles of the cotton swabs, thereby improving the success rate of detecting defective cotton swabs and improving product quality.

[0004] Preferably, the driving mechanism includes a drive motor, which is connected to the first rotating shaft via a transmission connection.

[0005] Preferably, the drive motor is fixedly connected to the bottom of the support plate via a motor bracket, and a drive wheel is fixedly connected to the power output shaft of the drive motor. A driven wheel corresponding to the drive wheel is fixedly connected to the first rotating shaft, and a transmission belt is tensioned between the drive wheel and the driven wheel.

[0006] Preferably, the vision mechanism includes a camera bracket, on which a camera for detecting cotton swabs is fixedly connected, and the camera's field of view is located directly above the rubber belt.

[0007] On the other hand, the present invention provides a cotton swab conveying device, which includes the aforementioned cotton swab visual inspection device. The device also includes a support frame, on which a first conveying mechanism for conveying cotton swabs is installed. The first conveying mechanism includes a first conveying chain for conveying cotton swabs, and the visual mechanism is located on the support frame above the first conveying chain.

[0008] Two first pulleys are located on both sides of the first conveyor chain, the top of the rubber belt abuts against the cotton swabs on the first conveyor chain, and the cotton swabs on the first conveyor chain are spaced apart from the bottom of the chain groove of the first conveyor chain.

[0009] Preferably, the first conveying mechanism further includes a first conveying toothed disc connected to the first conveying chain. The first conveying toothed disc and the first conveying chain are conveyed synchronously under the drive of the first transmission mechanism. A waste removal mechanism is installed on the support frame between the vision mechanism and the first conveying toothed disc. A second conveying mechanism is also installed on the support frame. The second conveying mechanism includes a second conveying toothed disc and a second conveying chain. The second conveying toothed disc and the second conveying chain are conveyed synchronously under the drive of the second transmission mechanism, and the second conveying toothed disc is connected to the first conveying toothed disc. The first transmission mechanism and the second transmission mechanism are driven by corresponding motors, and the transmission between the first transmission mechanism and the second transmission mechanism is connected or disconnected through two motors. When the transmission is disconnected, the second conveying toothed disc stops rotating, and the first conveying toothed disc continues to rotate to remove the vacant position before the transmission is connected. The second conveying toothed disc rotates synchronously with the first conveying toothed disc to avoid the appearance of vacant positions on the second conveying toothed disc.

[0010] Preferably, the support plate is detachably and fixedly connected to the support frame; the camera bracket is detachably and fixedly connected to the support frame.

[0011] The first conveying mechanism also includes two spaced-apart first conveying sprockets, with a first conveying chain tensioned between the two first conveying sprockets. A first conveying toothed disc is coaxially arranged with the first conveying sprocket near the second conveying toothed disc, and a second conveying toothed disc is staggered with the first conveying toothed disc. The second conveying mechanism also includes two spaced-apart second conveying sprockets, with a second conveying chain tensioned between the two second conveying sprockets.

[0012] The support plate is L-shaped, and the first and second rotating shafts are rotatably connected to the horizontal part of the support plate. The vertical part of the support plate has a vertically arranged strip hole, and the support plate is detachably fixed to the support frame through bolts in the strip hole.

[0013] Preferably, a horizontally arranged pressure plate is installed above the first conveyor chain. The pressure plate has two vertically spaced fixing holes. Two support rods corresponding to the fixing holes are fixedly connected to the support frame. The pressure plate is detachably fixed to the support rods by fixing bolts passing through the fixing holes.

[0014] Preferably, a baffle plate for blocking cotton swabs is detachably and fixedly connected to the support frame below the support rod. The baffle plate is arranged parallel to the pressure plate and is located on the side of the first conveyor chain near the support frame.

[0015] Preferably, the waste removal mechanism includes a waste removal plate and a waste removal drive. The waste removal drive is mounted on a support frame, and the waste removal plate is connected to the waste removal drive via a transmission connection. The waste removal drive includes a waste removal motor or a waste removal cylinder. The above solution has the following advantages:

[0016] The drive mechanism rotates the first rotating shaft in the opposite direction to the cotton swab conveying direction. The first rotating shaft drives the first pulley to rotate, and the first pulley drives the first pulley and the second pulley to rotate synchronously in the opposite direction via a rubber belt. The rubber belt between the first and second pulleys drives the cotton swab to rotate, with the bottom surface of the cotton swab rotating upwards. This allows the camera to collect image signals from various angles of the cotton swab, reducing blind spots in the camera's image signal acquisition and reducing the defect rate of cotton swabs. The vision mechanism can collect image information from the cotton swabs, improving production efficiency compared to manual screening of defective cotton swabs. The slotted holes on the support plate facilitate the adjustment of the support plate's horizontal height, ensuring that the rubber belt is at the appropriate height for the cotton swab flipping mechanism to flip the cotton swabs. The pressure plate restricts the vertical position of the cotton swab, preventing the cotton swabs on the first conveying chain from displacing excessively upwards under the action of the rubber belt and detaching from the first conveying chain, thus ensuring the smooth conveying of the cotton swabs.

Detailed Implementation

[0026] like Figure 1-8As shown, a visual inspection device for a rotatable cotton swab 9 is disclosed. This device includes a vision mechanism 4 for inspecting the cotton swab 9. The vision mechanism 4 can be an industrial camera 42 or a camera, etc. The vision mechanism 4 performs visual inspection by imaging, a relatively mature technology. Below the vision mechanism 4 is a cotton swab flipping mechanism 6. The cotton swab flipping mechanism 6 includes a support plate 61. A first rotating shaft 62 and a second rotating shaft 63, parallel and spaced apart, are mounted above the support plate 61. The first rotating shaft 62 and the second rotating shaft are rotatably mounted on the top of the support plate 61 via a bearing assembly 64. Two first pulleys 65 are fixed on the first rotating shaft 62, spaced apart. Two second pulleys 66, corresponding one-to-one with the first pulleys 65, are fixed on the second rotating shaft 63. A rubber belt 67 is tensioned between the first pulleys 65 and their corresponding second pulleys 66. The cotton swab flipping mechanism 6 also includes a drive mechanism for driving the first rotating shaft 62 or the second rotating shaft 63 to rotate. Here, the direction in which the cotton swab 9 moves forward is defined as the forward direction, and the direction parallel to and opposite to the forward direction of the cotton swab 9 is defined as the reverse direction. The drive mechanism drives the first rotating shaft 62 or the second rotating shaft 63 to rotate. Under the action of the rubber belt 67, the other rotating shaft rotates synchronously, realizing the rotation of the rubber belt 67. In order to realize the flipping of the cotton swab 9, the rubber belt 67 and the cotton swab flipping mechanism 6 are set up. The drive mechanism drives the first rotating shaft 62 or the second rotating shaft 63 to rotate, and the first rotating shaft 62 or the second rotating shaft 63 needs to drive the cotton swab 9 located on the rubber belt 67 to move in the reverse direction through the rubber belt 67. At the same time, the conveying device pushes the cotton swab 9 to move in the forward direction, thereby realizing the rotation of the cotton swab 9. This allows the vision mechanism 4 to collect image signals of the cotton swab 9 from various angles, so as to improve the success rate of detecting defective cotton swab 9 and improve product quality. The rubber belt 67 abuts against the cotton swab 9 located on the conveying device, and the rubber belt 67 moves in the opposite direction to the conveying device. Specifically, if the conveying device conveys the cotton swabs 9 via a chain tensioned on a sprocket, and the sprocket rotates clockwise, then the first rotating shaft 62 or the second rotating shaft 63 rotates counterclockwise. Figure 1 As shown, the conveying device drives the cotton swab 9 to move to the right, while the rubber belt 67 drives the cotton swab 9 to move to the left, thereby realizing the rotation of the cotton swab 9.

[0027] In another embodiment, the driving mechanism includes a drive motor 7, which is connected to a first rotating shaft 62. The drive motor 7 drives the first rotating shaft 62 to rotate, and the first rotating shaft 62 drives a second rotating shaft 63 to rotate synchronously via a rubber belt 67.

[0028] In another embodiment, the drive motor 7 is fixedly connected to the bottom of the support plate 61 via a motor bracket 71, and a drive wheel 72 is fixedly connected to the power output shaft of the drive motor 7. A driven wheel 73, corresponding to the drive wheel 72, is fixedly connected to the first rotating shaft 62. A transmission belt is tensioned between the drive wheel 72 and the driven wheel 73. The drive motor 7 drives the driven wheel 73 to rotate via the drive wheel 72 and the transmission belt 74, thereby driving the first rotating shaft 62 to rotate via the driven wheel 73. Under the action of the rubber belt 67, the first pulley 65 and the second pulley 66 rotate synchronously.

[0029] In another embodiment, the vision mechanism 4 includes a camera bracket 41, on which a camera 42 for detecting cotton swabs 9 is fixedly connected. The field of view of the camera 42 is located directly above the rubber belt 67 to facilitate visual detection of the cotton swabs 9 located on the rubber belt 67 and obtain image data of the cotton swabs 9. The camera 42 is connected to a power supply, a video recorder, and a PLC controller via cables; this is prior art and will not be described in detail here. Furthermore, an additional light source can be configured at the camera 42 to improve the detection accuracy to some extent.

[0030] On the other hand, this utility model provides a cotton swab conveying device, which includes the aforementioned cotton swab visual inspection device. The device also includes a body 1, which includes a support frame 11. A first conveying mechanism 2 for conveying cotton swabs 9 is installed on the support frame 11. The first conveying mechanism 2 includes a first conveying chain 21. A visual mechanism 4 is located on the support frame 11 above the first conveying chain 21. Two first pulleys 65 are located on both sides of the first conveying chain 21, that is, the first rotating shaft 62 and the second rotating shaft 63 are both parallel to the central axis of the length direction of the cotton swab 9. The first conveying chain 21 is located at the interval between the two first pulleys 65. Correspondingly, the first conveying chain 21 is also located at the interval between the two second pulleys 66. The top of the rubber belt 67 abuts against the cotton swab 9 located on the first conveying chain 21, and the cotton swab 9 located on the first conveying chain 21 is spaced apart from the bottom of the chain groove of the first conveying chain 21. Specifically, under normal circumstances, under the influence of gravity, the cotton swab 9 located on the first conveyor chain 21 is positioned within the chain groove 23 and abuts against the bottom of the chain groove 23, such as... Figure 8 When the cotton swab 9 on the left side is conveyed to the rubber belt 67, because the top of the rubber belt 67 is slightly higher than the bottom of the chain groove 23 on the first conveyor chain 21, the cotton swab 9 located at the bottom of the chain groove 23 is disengaged from the bottom of the chain groove 23, and there is a certain gap between the cotton swab 9 and the bottom of the chain groove 23. Figure 8The cotton swab on the right side is positioned with its bottom resting on the rubber belt 67. Since the rubber belt 67 rotates in the opposite direction to the first conveyor chain 21, the cotton swab 9 rotates, allowing the vision mechanism 4 to acquire images of the cotton swab 9 from all angles, thus improving the accuracy of cotton swab detection. This setup facilitates the flipping of the cotton swab during transport, enabling detection.

[0031] The first conveying mechanism 2 also includes a first conveying toothed disc 22 connected to the first conveying chain 21. A second conveying mechanism 3 is also installed on the support frame 11. The second conveying mechanism 3 includes a second conveying toothed disc 31 and a second conveying chain 32. The second conveying toothed disc 31 is connected to the second conveying chain 32, and the second conveying toothed disc 31 is also connected to the first conveying toothed disc 22. A waste rejection mechanism 5 is installed on the support frame 11 between the vision mechanism 4 and the first conveying toothed disc 22. The first conveying chain 21 conveys the finished product, such as a cotton swab 9, to the first conveying toothed disc 22 (the first conveying toothed disc 22 is provided with concave grooves that are adapted to the cotton swab 9). Since the second conveying toothed disc 31 is connected to the first conveying toothed disc 22, the cotton swab 9 can be easily conveyed to the second conveying chain 32 through the concave grooves on the second conveying toothed disc 31. The vision mechanism 4 inspects the cotton swabs 9 on the first conveyor chain 21 to determine whether the cotton swabs 9 are qualified. The rejection mechanism is located between the vision mechanism 4 and the first conveyor toothed disc 22 so that the cotton swabs 9 after being inspected by the vision mechanism 4 can be conveyed to the rejection mechanism 5. The rejection mechanism 5 performs rejection operation if there are unqualified products based on the inspection results of the vision mechanism 4.

[0032] In this system, the first conveyor chain 21 and the first conveyor toothed disc 22 are synchronously conveyed under the drive of the same transmission mechanism (referred to as the first transmission mechanism; only a partial structure of the first conveyor chain 21 is shown in the figure, but in reality, the first conveyor chain 21 is a complete conveying line). Similarly, the second conveyor chain 32 and the second conveyor toothed disc 31 are synchronously conveyed under the drive of the same transmission mechanism (referred to as the second transmission mechanism). The first transmission mechanism and the second transmission mechanism can be driven by different motors. The drive motor of the first transmission mechanism is referred to as the first drive motor, and the drive motor of the second transmission mechanism is referred to as the second drive motor. When the second drive motor stops, the second transmission mechanism closes, and the transmission between the first and second transmission mechanisms is disconnected. When the second drive motor starts, the transmission between the first and second transmission mechanisms is connected. When the transmission is disconnected, the second conveying toothed disc 31 stops, and the first conveying toothed disc 22 continues to rotate. After the first conveying toothed disc 22 rotates and completes the empty position on its tooth groove (i.e., the tooth groove is not filled with cotton swabs 9, which may be caused by the rejection mechanism 5), the second conveying toothed disc 31 rotates again to convey and connect with the first conveying toothed disc 22. Meanwhile, a sensor is installed on the support frame 11 to detect the cotton swabs in the groove of the first conveying toothed disc 22. The sensor is located on the rear side of the first conveying toothed disc 22 to detect the empty position of the first conveying toothed disc 22. After the empty position is detected, when the empty position is conveyed to a position close to the second conveying toothed disc 31, the second drive motor is stopped to disconnect the transmission and facilitate the empty position to be moved away. Thus, the second conveying toothed disc 31 is not affected by the empty position on the first conveying toothed disc 22, and there is no empty position on the second conveying toothed disc 31. The second conveying toothed disc 31 conveys the cotton swabs 9 evenly and at equal intervals to the second conveying chain 32 to ensure the stability of the number of cotton swabs 9 in the subsequent packaging process.

[0033] Furthermore, the first transmission mechanism and the second transmission mechanism can be driven by the same motor, and the second transmission mechanism can connect or disconnect the transmission between the two transmission mechanisms through a transmission clutch device. After the sensor detects that there is a gap on the first conveying toothed disk 22, the sensor feeds back the signal to the transmission clutch device through the controller, the second transmission mechanism is closed, the second conveying toothed disk 31 stops rotating, and the second transmission mechanism is started after the gap on the first conveying toothed disk 22 has been completed.

[0034] The first conveying mechanism further includes two spaced-apart first conveying sprockets (not shown in the figure). A first conveying chain 21 is tensioned between the two first conveying sprockets. A first conveying toothed disc 22 can be connected to the first conveying chain 21 via gears or other transmissions. In this embodiment, the first conveying toothed disc 22 is coaxially arranged with the first conveying sprocket near the second conveying toothed disc 31, and the first conveying toothed disc 22 is located outside the first conveying sprocket. There are two first conveying toothed discs 22, and the two first conveying toothed discs 22 are coaxial and spaced apart, so that the two ends of the cotton swab are respectively located at the two first conveying sprockets. The first conveying toothed disc 22 has a larger outer diameter than the first conveying sprocket. There are two second conveying toothed discs 31, which are coaxial and spaced apart. The second conveying toothed discs 31 and the first conveying toothed disc 22 are staggered to achieve their connection. The second conveying mechanism 3 also includes two spaced second conveying sprockets 33. The second conveying chain 32 is tensioned between the two second conveying sprockets 33. The second conveying sprockets 33 are coaxial with the second conveying toothed discs 31 or are connected by gear transmission.

[0035] In another embodiment, the support plate 61 is detachably and fixedly connected to the support frame 11 to facilitate the maintenance and replacement of components located on the support plate 61. The camera bracket 41 is detachably and fixedly connected to the support frame 11 to facilitate the maintenance and replacement of the camera 42.

[0036] In another embodiment, the support plate 61 is L-shaped. The first rotating shaft 62 and the second rotating shaft 63 are both rotatably connected to the horizontal portion of the support plate 61. A vertically oriented slot 68 is provided on the vertical portion of the support plate 61. The support plate 61 is detachably and fixedly connected to the support frame 11 via bolts within the slot 68. By arranging the support plate 61 in an L-shape, installation of the support plate 61 is facilitated. The slot 68 allows for adjustment of the height of the horizontal portion of the support plate 61 by selecting the bolt installation position within the slot 68, thereby facilitating the adjustment of the height of the rubber belt 67 and enabling the flipping of the cotton swab 9.

[0037] In another embodiment, a horizontally arranged pressure plate 8 is installed above the first conveyor chain 21. The pressure plate 8 has two vertically spaced fixing holes 82. Two support rods 81, corresponding one-to-one with the fixing holes 82, are fixedly connected to the support frame 11. The pressure plate 8 is detachably fixed to the support rods 81 by fixing bolts passing through the fixing holes 82. The fixing holes 82 facilitate the adjustment of the height of the pressure plate 8, thereby adjusting the distance between the pressure plate 8 and the first conveyor chain 21 and the rubber belt 67. This helps to limit the movement of the cotton swabs 9 on the first conveyor chain 21 and the rubber belt 67, preventing the rubber belt 67 from lifting the cotton swabs 9 too high and causing them to disengage from the chain groove 23 of the first conveyor chain 21. This ensures that during the movement of the first conveyor chain 21, the sidewall of the chain groove 23 still exerts a certain pushing force on the cotton swabs 9, enabling their rotation and reducing misalignment.

[0038] In another embodiment, a baffle plate 83 for blocking the cotton swab 9 is detachably and fixedly connected to the support frame 11 below the support rod 81. The baffle plate 83 is arranged parallel to the pressure plate 8 and is located on the side of the first conveyor chain 21 near the support frame 11. The baffle plate 83 reduces the longitudinal movement of the cotton swab 9, thereby reducing the occurrence of the cotton swab 9 detaching from the first conveyor chain 21.

[0039] In another embodiment, the waste removal mechanism 5 includes a waste removal plate and a waste removal drive. The waste removal drive is mounted on the support frame 11, and the waste removal plate is drive-connected to the waste removal drive. The waste removal drive includes a waste removal motor or a waste removal cylinder. The waste removal drive is connected to a power supply and a PLC controller via a cable. The vision mechanism 4 sends the detected image to the PLC controller, which then activates the waste removal drive. The waste removal drive drives the waste removal plate to remove the waste swabs 9 located on the first conveyor chain 21. The waste removal mechanism 5 is prior art and will not be described in detail here.

[0040] Usage process:

[0041] In use, the first conveyor chain 21 drives the cotton swab 9 to move forward. The camera 42 above the first conveyor chain 21 captures images of the cotton swab 9 and transmits the captured image information to the PLC controller. Simultaneously, the drive motor 7 is started. The drive motor 7 drives the driven wheel 73 to rotate through the drive wheel 72 and the transmission belt, thereby driving the first pulley 65 and the second pulley 66 to rotate synchronously through the first rotating shaft 62. The rubber belt 67 tensioned between the first pulley 65 and the second pulley 66 moves in the opposite direction to the first conveyor chain 21. When the cotton swab 9 is conveyed to the rubber belt 67, since the height of the rubber belt 67 is slightly higher than the bottom of the chain groove 23 of the first conveyor chain 21, the bottom of the cotton swab 9 abuts against the rubber belt 67 and the bottom of the cotton swab 9 is in contact with the chain groove 23 of the first conveyor chain 21. The bottom part separates, and the cotton swab 9 moves in the reverse direction under the action of the rubber belt 67. At the same time, the side wall of the chain groove 23 of the first conveyor chain 21 pushes the cotton swab 9 to move in the forward direction, thereby realizing the 360° rotation of the cotton swab 9. This allows the camera 42 to collect different angles of the cotton swab 9. After the camera 42 transmits the collected image signal of the cotton swab 9 to the PLC controller, the PLC controller controls and starts the waste removal motor. The waste removal motor drives the waste removal plate to remove the waste cotton swab 9 on the first conveyor chain 21. After there is a gap on the first conveyor chain 21, the cotton swab 9 is replenished at the gap at the first conveyor toothed disc 22 and the second conveyor toothed disc 31 (this is the prior art and will not be described in detail here). Then, the high-quality cotton swab 9 is conveyed to the second conveyor chain 32 and enters the next process under the conveying of the second conveyor chain 32.
