Description

Technical Field

[0001] This invention relates to the field of willow weaving processing technology, specifically to an automatic conveying device for the production and processing of willow weaving products based on industrial vision. Background Technology

[0002] Willow woven products are handicrafts made from flexible willow twigs using traditional techniques such as weaving and winding. They combine the characteristics of being natural and environmentally friendly, durable, breathable, and practical with diverse and beautiful designs. (See attached instruction manual.) Figure 15 As shown, this is a common willow woven bucket on the market. During the drying and shaping process, the moisture in the willow branches evaporates due to heat, and the willow branches are prone to deformation due to temperature changes. The product has a certain probability of quality problems such as chipping and curling. Therefore, an appearance inspection of the willow woven bucket is required between the drying process and the warehousing process.

[0003] Conveying devices play a crucial role in the production line processing of willow woven barrels, transporting products and connecting different processes. However, traditional conveying devices, such as conveyor belts and roller conveyors, cannot meet the requirements for the appearance inspection of willow woven barrels. Whether the barrels are placed upright or upside down on the conveying device, there are obstructions, limiting the scope of inspection and resulting in low efficiency. Therefore, improving traditional conveying devices to integrate with industrial vision technology and enhance the efficiency of appearance inspection of willow woven barrels has become an urgent problem to be solved in the industry. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic conveying device for the production and processing of willow woven products based on industrial vision, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An automated conveying device for willow weaving production and processing based on industrial vision includes a base, a conveyor belt, and a tray. The conveyor belt is mounted above the base via a mounting frame. A dual-axis moving assembly is located downstream of the conveyor belt on the base, and the tray is mounted on the dual-axis moving assembly. The tray is used for inverting willow weaving barrels, and the dual-axis moving assembly is used to adjust the tray vertically and horizontally between the transfer station and the inspection station. An inner support mechanism is provided on the tray to support and raise the willow weaving barrels from the inside. An adjustment mechanism is provided above the base, and the moving end of the adjustment mechanism has two symmetrically distributed semi-circular brackets. The adjustment mechanism is linked with the dual-axis moving assembly to drive the two semi-circular brackets to move closer or further apart. When the two semi-circular brackets are close to each other to their limit position, they form a ring structure downstream of the conveyor belt, which is used to support and suspend the willow weaving barrels above the transfer station.

[0007] Preferably, the internal support mechanism includes a threaded rod, an internal threaded sleeve, a first drive motor, and a pusher cylinder; the threaded rod is vertically and rotatably mounted on the tray, and the internal threaded sleeve is threadedly fitted onto the threaded rod; a hollow frame is fixed at the bottom of the tray, the first drive motor is fixed inside the hollow frame, and the output shaft of the first drive motor is fixedly connected to the bottom end of the threaded rod; the pusher cylinder is mounted on the top end of the internal threaded sleeve; an annular platform is fixed on the tray, distributed around the axis of the internal threaded sleeve, and several hinged arms A are hingedly mounted in an annular array on the annular platform; a... The ring seat has several hinged arms B mounted in a ring array. The ends of hinged arms B are hinged to the ends of hinged arms A one-to-one, and the connection between hinged arms B and hinged arms A can form hinged corners. When the top end face of the willow woven barrel abuts against the upper surface of the tray and the internal threaded sleeve moves down to its limit position, each hinged corner abuts against the inner edge wall of the willow woven barrel, while there is a clearance space between the pusher cylinder and the inner bottom wall of the willow woven barrel. When the internal threaded sleeve moves up to its limit position, the pusher cylinder abuts against the inner bottom wall of the willow woven barrel, while there is a clearance space between the top end face of the willow woven barrel and the tray.

[0008] Preferably, the pusher cylinder is rotatably mounted on the end of the internal threaded sleeve, and the pusher cylinder is equipped with a driving device; the driving device is used to drive the pusher cylinder to rotate around the axis of the internal threaded sleeve.

[0009] Preferably, the dual-axis moving assembly includes a push cylinder and a power guide rail; there are two push cylinders, which are symmetrically fixed on the base, and the telescopic ends of the two push cylinders are both facing upwards; the power guide rail is fixed on the telescopic ends of the two push cylinders, and a moving seat is provided on the power guide rail, with a hollow frame installed on the moving seat; wherein, the end of the power guide rail closer to the conveyor belt is the transfer station, and the end farther from the conveyor belt is the inspection station.

[0010] Preferably, the adjusting mechanism includes a bidirectional screw, a nut seat, a driven gear, and a rack; two columns are symmetrically fixed on the base, the bidirectional screw is rotatably installed between the two columns, and a guide rod is also fixed between the two columns; two nut seats are symmetrically threaded on both sides of the bidirectional screw, and both nut seats are slidably fitted on the guide rod; a driven gear is fixedly fitted in the middle of the bidirectional screw; the rack is fixed to the side of the power guide rail through a connecting arm, and the rack meshes with the driven gear; an L-shaped connecting rod is fixed to the side of each of the two nut seats, a connecting plate is fixed to the top of each of the two connecting rods, and two semi-annular brackets are fixed to the side of the connecting plate one by one.

[0011] Preferably, a bracket is fixed to one side of the mounting frame, and an industrial vision camera B is fixed to the end of the bracket to detect the state of the willow wicker bucket falling onto the tray.

[0012] Preferably, the driving device includes a drive motor and a main gear; the drive motor is fixed on the side wall of the push cylinder, and the main gear is fixed on the output shaft of the drive motor; a toothed ring is fixed on the outer wall of the internal threaded sleeve, and the toothed ring meshes with the main gear.

[0013] Preferably, a U-shaped seat is fixed on the movable seat, and a shaft is rotatably mounted on the U-shaped seat; a second drive motor is fixed on the side of the U-shaped seat, and the output end of the second drive motor is correspondingly and fixedly connected to one end of the shaft; a frame is fixedly fitted on the shaft, and a hollow frame is fixed on the frame.

[0014] Preferably, two inclined guide troughs are fixedly installed on the base by a support frame, and the two guide troughs are symmetrically distributed on both sides of the testing station.

[0015] Preferably, the top end face of the push cylinder is evenly distributed with several anti-slip protrusions.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] 1. This invention uses an inverted conveying method to expose the outer surface of the willow woven bucket. The lifting and rotating design of the top pusher ensures that the inner side and end face of the willow woven bucket are not obstructed. Combined with multiple industrial vision inspection technologies, it can collect images of areas that are traditionally difficult to photograph, such as the inner and outer surfaces, corners, and end faces of the willow woven bucket, without blind spots. This solves the problem of blind spots caused by the support structure, while reducing manual intervention and improving inspection efficiency.

[0018] 2. This invention utilizes an industrial vision camera B to detect the posture of the willow wicker bucket as it falls onto the pallet in real time. If it becomes skewed, the dual-axis moving assembly is controlled to drive the pallet downwards. Simultaneously, the adjustment mechanism drives the two semi-circular brackets to move closer to each other, forming a clamping and straightening effect. In conjunction with industrial vision technology, this invention reduces detection errors caused by the posture deviation of the willow wicker bucket during the conveying process and improves the efficiency of the connection between the detection process and the conveying process.

[0019] 3. The present invention, through the hinged engagement of hinge arm B and hinge arm A, not only limits the internal threaded sleeve, but also, when the willow woven bucket falls onto the tray, the hinged corners formed by hinge arm A and hinge arm B, evenly distributed around the internal threaded sleeve, abut against the inner edge wall of the willow woven bucket, which can achieve a self-centering effect on the willow woven bucket, ensuring that the pusher can subsequently abut against the center of the inner bottom wall of the willow woven bucket, thereby ensuring that the pusher can push the willow woven bucket upward smoothly and avoid the willow woven bucket tilting or leaning due to instability of the center of gravity.

[0037] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0038] It is worth noting that, such as Figure 16 As shown, the main areas where willow woven buckets are prone to chipping and warping during drying are the outer circumference surface 01, bottom surface 02, outer corner 03, top end face 04, inner edge wall 05, inner bottom wall 06, and inner corner 061. Therefore, it is necessary to focus on defect detection in the above-mentioned areas.

[0039] Example 1: Please refer to Figures 1-14 This invention provides an automatic conveying device for the production and processing of willow woven products based on industrial vision. The automatic conveying device is set in the appearance inspection process and connects with the upstream and downstream processes. It is mainly used to convey willow woven buckets and cooperate with the vision inspection system to detect defects in the appearance of the willow woven buckets.

[0040] The automatic conveying device includes a base 1, a conveyor belt 2, and a tray 4. A mounting frame 201 is provided on one side of the base 1, and the conveyor belt 2 is mounted on the mounting frame 201 for conveying willow woven barrels from upstream to downstream. A dual-axis moving assembly 3 is provided on the base 1 downstream of the conveyor belt 2, and the tray 4 is mounted on the dual-axis moving assembly 3. The tray 4 is used for placing the willow woven barrels upside down. Through the operation of the dual-axis moving assembly 3, the tray 4 can be adjusted up and down and moved left and right between the transfer station 07 and the inspection station 08. An inner support mechanism 5 is provided on the tray 4 for supporting and lifting the willow woven barrels away from the tray 4 from the inside upwards.

[0041] An adjustment mechanism 6 is provided above the base 1. The moving end of the adjustment mechanism 6 has two symmetrically distributed semi-annular brackets 21. The adjustment mechanism 6 is linked with the dual-axis moving group 3 to drive the two semi-annular brackets 21 to move closer or further apart. Specifically, when the dual-axis moving group 3 drives the tray 4 upward, the adjustment mechanism 6 drives the two semi-annular brackets 21 to move away from each other under the transmission action of the dual-axis moving group 3 and the adjustment mechanism 6. When the dual-axis moving group 3 drives the tray 4 downward, the adjustment mechanism 6 drives the two semi-annular brackets 21 to move closer together. When the two semi-annular brackets 21 move closer to each other to the limit position, the two semi-annular brackets 21 form a ring structure downstream of the conveyor belt 2. This ring structure is used to receive the willow woven buckets conveyed by the conveyor belt 2 and support and suspend the willow woven buckets above the transfer station 07. In addition, the top of the inner support mechanism 5 has a push cylinder 7, which abuts against the inner bottom wall surface 06 of the willow woven bucket, and the push cylinder 7 can rotate and adjust.

[0042] Among them, such as Figure 8 , Figure 9 and Figure 11 As shown, the inner support mechanism 5 includes a threaded rod 51, an internal threaded sleeve 52, and a first drive motor 55. The threaded rod 51 is vertically rotatably mounted on the tray 4. The internal threaded sleeve 52 is threadedly fitted onto the threaded rod 51. A hollow frame 42 is fixed at the bottom of the tray 4. The first drive motor 55 is fixed inside the hollow frame 42, and the output shaft of the first drive motor 55 is fixedly connected to the bottom end of the threaded rod 51. The push cylinder 7 is mounted on the top end of the internal threaded sleeve 52. An annular platform 41 distributed around the axis of the internal threaded sleeve 52 is fixed on the tray 4. Several hinged arms A53 are mounted in an annular array on the annular platform 41. An annular seat 521 is fixedly fitted on the outer wall of the internal threaded sleeve 52 near the push cylinder 7. Several hinged arms B54 are mounted in an annular array on the annular seat 521. The ends of the hinged arms B54 are hinged one-to-one with the ends of the hinged arms A53.

[0043] The first drive motor 55 operates, driving the threaded rod 51 to rotate forward or backward. The forward-rotating threaded rod 51, in conjunction with the limiting action of the hinged arms A53 and B54, can thread-drive the internal threaded sleeve 52 upward for adjustment. The reverse-rotating threaded rod 51 can thread-drive the internal threaded sleeve 52 downward for adjustment. During the upward and downward adjustment of the internal threaded sleeve 52, the hinged arms A53 and B54 undergo hinged oscillation, and... Figure 11 As shown, the connection between hinge arm B54 and hinge arm A53 can form a hinge angle 501.

[0044] Specifically, when the internal threaded sleeve 52 descends to its limit position, the distance between the two opposing hinged corners 501 is less than the opening diameter of the willow wicker bucket, so that the inverted willow wicker bucket can be fitted onto the inner support mechanism 5. Furthermore, as... Figure 13 As shown, when the top end face 04 of the willow wicker bucket abuts against the upper surface of the tray 4, and the internal threaded sleeve 52 descends to its limit position, each hinged corner 501 abuts against the inner edge wall 05 of the willow wicker bucket. Simultaneously, there is clearance space between the pusher cylinder 7 and the inner bottom wall 06 of the willow wicker bucket. Figure 14 As shown, when the internal threaded sleeve 52 moves to its limit position, each hinge arm B54 and hinge arm A53 swings to a vertical state, and the push cylinder 7 abuts against the inner bottom wall 06 of the willow woven barrel. At the same time, there is a clearance space between the top end face 04 of the willow woven barrel and the tray 4.

[0045] Example 2: Based on Example 1, this example combines the device with the detection system by setting a detection camera at a corresponding location to achieve appearance inspection of willow woven buckets, as detailed below:

[0046] Please see Figure 1 and Figure 4 A vertical stand 12 is fixed on the side of the inspection station 08 on the base 1. An industrial vision camera A13 is installed at an angle on the top of the stand 12. The industrial vision camera A13 is used to photograph and inspect the outer peripheral surface 01, the bottom surface 02, and the outer corner 03 of the willow woven bucket.

[0047] Please see Figure 11 An industrial vision camera E523 is fixed on the top of the internal threaded sleeve 52. The industrial vision camera E523 is used to photograph and inspect the bottom wall surface 06 and the corner 061 inside the willow woven barrel. The industrial vision camera E523 is located inside the push cylinder 7, and the shooting end is slightly lower than the top end face of the push cylinder 7. This ensures that the shooting range of the industrial vision camera E523 is sufficient to cover the bottom wall surface 06 and the corner 061 inside the willow woven barrel, while also ensuring that the industrial vision camera E523 will not come into contact with the bottom wall surface 06 inside the willow woven barrel and damage the lens.

[0048] Please see Figure 9 and Figure 12An industrial vision camera D522 is installed on the outer wall of the internal threaded sleeve 52 and near the bottom of the internal threaded sleeve 52. The industrial vision camera D522 is used to photograph and inspect the inner edge wall 05 of the willow woven barrel.

[0049] Please see Figure 9 and Figure 10 A vertical through hole 401 is made on the tray 4, and an industrial vision camera C402 is installed in the through hole 401. The industrial vision camera C402 is used to photograph and inspect the top end face 04 of the willow woven barrel. The industrial vision camera C402 extends downward to the bottom of the tray 4, and the shooting end of the industrial vision camera C402 is set below the upper surface of the tray 4 to avoid the shooting end of the industrial vision camera C402 from contacting the top end face 04 of the willow woven barrel and causing damage.

[0050] The principle of detecting appearance defects in willow woven buckets is as follows:

[0051] First, the dual-axis moving assembly 3 drives the pallet 4 downward to its limit position, ensuring that the pallet 4 is at the transfer station 07. Under the transmission action of the adjusting mechanism 6, the two semi-circular brackets 21 are driven to approach each other to their limit positions, forming a circular structure (e.g., Figure 2 As shown in the diagram, the willow woven bucket is transferred from the upstream process to the conveyor belt 2 (the willow woven bucket is inverted). The conveyor belt 2 transports the willow woven bucket downstream to the above-mentioned circular structure. At the same time, the first drive motor 55 drives the internal threaded sleeve 52 to descend to the limit position, and the hinged arm A53 and hinged arm B54 swing when they are connected.

[0052] Next, the dual-axis moving assembly 3 drives the tray 4 and the inner support mechanism 5 to move upward as a whole for adjustment. Under the transmission action of the adjustment mechanism 6, the two semi-circular brackets 21 are moved away from each other until the diameter between the two semi-circular brackets 21 is greater than the maximum diameter of the willow woven bucket. At this point, the willow woven bucket falls downward from between the two semi-circular brackets 21 onto the tray 4 and is fitted onto the outside of the inner support mechanism 5, as shown in the image. Figure 13 As shown, at this time, the top end face 04 of the willow woven barrel abuts against the tray 4, and each hinge corner 501 abuts against the inner edge wall 05 of the willow woven barrel. At the same time, there is a certain distance between the push cylinder 7 and the inner bottom wall 06 of the willow woven barrel, which makes room for the shooting angle of the industrial vision camera E523. Then, through the operation of the dual-axis moving group 3, the tray 4, the inner support mechanism 5 and the willow woven barrel are driven to move to the inspection station 08.

[0053] Next, the bottom surface 02 of the willow woven bucket is photographed by industrial vision camera A13, and the inner bottom wall surface 06 and the inner corner 061 of the willow woven bucket are photographed by industrial vision camera E523. The industrial vision cameras A13 and E523 upload the captured images to the system for processing to detect whether there are defects on the bottom surface 02, the inner bottom wall surface 06, and the inner corner 061 of the willow woven bucket.

[0054] If there are no defects on the bottom surface 02, the inner bottom wall surface 06, and the inner corner 061 of the willow woven bucket, then the first drive motor 55 drives the threaded rod 51 to rotate, which in turn drives the inner threaded sleeve 52 to move upward. The pusher cylinder 7 moves upward synchronously with the inner threaded sleeve 52 and will abut against the inner bottom wall surface 06 of the willow woven bucket. Then, the inner threaded sleeve 52 continues to move upward to its limit position until the pusher cylinder 7 pushes the adjusting mechanism 6 upward, so that the top end face 04 of the willow woven bucket and the upper surface of the tray 4 reach a predetermined distance, ensuring that the top end face 04 of the willow woven bucket will not obstruct the shooting of the industrial vision camera C402. The specific state is as follows: Figure 14 As shown;

[0055] Subsequently, the top pusher 7 rotates, and under the frictional force of its contact with the inner bottom wall surface 06 of the willow woven bucket, it drives the willow woven bucket to rotate synchronously. During the rotation of the willow woven bucket, industrial vision cameras A13, D522 and C402 take multiple photos at intervals and upload them to the system for analysis and processing to detect whether there are defects on the outer peripheral surface 01, the outer corner 03, the inner edge wall 05, and the top end face 04 of the willow woven bucket. The interval shooting of multiple photos, in conjunction with the rotation of the willow woven bucket, ensures that the detection range is sufficient to cover the entire circumference of the willow woven bucket.

[0056] During the above process, the dual-axis moving group 3 and the adjusting mechanism 6 work together to drive the two half-ring brackets 21 away from each other. At the same time, the dual-axis moving group 3 drives the tray 4 and the inner support mechanism 5 to move upward, which can reduce the distance between the tray 4 and the willow woven bucket, ensure that the willow woven bucket can fall smoothly onto the tray 4, and reduce the situation where the willow woven bucket is tilted or skewed due to excessive impact caused by the excessive distance between the tray 4 and the willow woven bucket.

[0057] The industrial vision camera D522 is positioned near the bottom of the internal threaded sleeve 52. When the internal threaded sleeve 52 moves upward to its limit position, such as... Figure 14 As shown, at this time, the industrial vision camera D522 is positioned close to the middle height of the willow wicker bucket to ensure that its shooting and detection range can sufficiently cover the vertical span of the inner edge wall 05 of the willow wicker bucket, thereby improving the accuracy of the detection results.

[0058] Furthermore, the hinged engagement of hinged arms B54 and A53 not only limits the internal threaded sleeve 52, but also, when the willow woven bucket falls onto the tray 4, the hinged corners 501 formed by hinged arms A53 and B54, evenly distributed around the internal threaded sleeve 52, abut against the inner edge wall 05 of the willow woven bucket. This provides a self-centering effect for the willow woven bucket, ensuring that the pusher 7 can subsequently abut against the center of the inner bottom wall 06 of the willow woven bucket. This ensures that the pusher 7 can smoothly push the willow woven bucket upwards, preventing the willow woven bucket from tilting due to instability. In addition, when the internal threaded sleeve 52 reaches its limit position, each hinged arm B54 and hinged arm A53 swings to a vertical position, not contacting the inner edge wall 05 of the willow woven bucket, thus avoiding resistance to the rotation of the willow woven bucket following the pusher 7.

[0059] It is worth noting that lighting lamps (not shown in the figure) are provided next to each industrial vision camera in this application to ensure the lighting environment when each industrial vision camera is shooting and inspecting. In addition, each industrial vision camera and the vision inspection system used adopt existing technology, and the specific structure and principle will not be described in detail.

[0060] like Figure 12 As shown, several anti-slip protrusions are evenly distributed on the top end face of the push cylinder 7. When the push cylinder 7 contacts the bottom wall surface 06 of the willow woven bucket, these anti-slip protrusions can increase the friction between the top of the push cylinder 7 and the bottom wall surface 06 of the willow woven bucket, so as to avoid the push cylinder 7 being unable to drive the willow woven bucket to rotate synchronously due to slippage, thus affecting the shooting and detection effect.

[0061] Example 3: Please refer to Figure 9 and Figure 11 Based on the aforementioned embodiments, this embodiment provides a detailed explanation of the installation method of the push cylinder 7, as follows:

[0062] The push cylinder 7 is rotatably mounted on the end of the internal threaded sleeve 52. The push cylinder 7 is equipped with a drive device 8, which is used to drive the push cylinder 7 to rotate around the axis of the internal threaded sleeve 52. The drive device 8 includes a drive motor 82 and a main gear 83. The drive motor 82 is fixed on the side wall of the push cylinder 7, and the main gear 83 is fixed on the output shaft of the drive motor 82. A gear ring 81 is fixed on the outer wall of the internal threaded sleeve 52, and the gear ring 81 meshes with the main gear 83. When the drive motor 82 works, its output shaft can drive the main gear 83 to rotate. Under the driving action of meshing with the gear ring 81, the rotating main gear 83 can drive the push cylinder 7 to rotate around the internal threaded sleeve 52 in the opposite direction, thereby providing a stable drive for the push cylinder 7 to drive the willow woven bucket to rotate synchronously.

[0063] Example 4: Please refer to Figure 4 , Figure 5 and Figure 7Based on the aforementioned embodiments, this embodiment provides a detailed explanation of the installation method of tray 4, as follows:

[0064] The dual-axis moving assembly 3 includes a push cylinder 31 and a power guide rail 32. There are two push cylinders 31, which are symmetrically fixed on the base 1, and the telescopic ends of the two push cylinders 31 are both facing upwards. The power guide rail 32 is fixed on the telescopic ends of the two push cylinders 31. A movable seat 321 is provided on the power guide rail 32, and a hollow frame 42 is installed on the movable seat 321. The end of the power guide rail 32 closer to the conveyor belt 2 is the transfer station 07, and the end farther from the conveyor belt 2 is the inspection station 08. The push cylinder 31 is selected from pneumatic cylinders, electric cylinders, or hydraulic cylinders. The power guide rail 32 adopts a linear drive structure such as a screw mechanism. Through the telescopic operation of the push cylinder 31, its telescopic end can drive the power guide rail 32 and the tray 4 to adjust in height. Through the operation of the power guide rail 32, it can drive the movable seat 321 to move and adjust between the transfer station 07 and the inspection station 08, thereby realizing the biaxial translation adjustment of the tray 4.

[0065] like Figure 8 As shown, a U-shaped seat 9 is fixed on the movable seat 321, and a shaft 91 is rotatably mounted on the U-shaped seat 9. A second drive motor 93 is fixed to the side of the U-shaped seat 9, and the output end of the second drive motor 93 is correspondingly and fixedly connected to one end of the shaft 91. A bracket 92 is fixedly fitted on the shaft 91, and a hollow frame 42 is fixed on the bracket 92. In addition, as shown... Figure 4 As shown, two inclined guide troughs 11 are fixedly installed on the base 1 by a support frame, and the two guide troughs 11 are symmetrically distributed on both sides of the inspection station 08. One guide trough 11 is used to guide good products, and the other guide trough 11 is used to guide defective products.

[0066] By setting conveyor belts (not shown in the figure) at the downstream ends of the two guide troughs 11, the second drive motor 93 drives the shaft 91 and the frame 92 to rotate, which can drive the tray 4 and the inner support mechanism 5 to swing to one side. If a willow woven bucket has a defect, the tray 4 and the inner support mechanism 5 are driven to swing to the defective product side and tilt downward. The defective willow woven bucket slides off the inner support mechanism 5 and falls onto the guide trough 11 on that side. The guide trough 11 then guides the willow woven bucket to the conveyor belt on that side, so that the defective willow woven bucket can be transported to the subsequent defective product process. If there is no defect on the willow woven bucket, the second drive motor 93 drives the tray 4 and the inner support mechanism 5 to swing to the other side, so that the willow woven bucket slides onto the other side of the conveyor belt, so that the willow woven bucket with good appearance can continue to be transported downstream, thereby realizing the sorting of defective willow woven buckets.

[0067] Example 5: Please refer to Figures 2-6Based on the foregoing embodiments, this embodiment provides a detailed explanation of the adjustment mechanism 6, as follows:

[0068] The adjusting mechanism 6 includes a bidirectional screw 62, a nut seat 63, a driven gear 64, and a rack 65. Two columns 61 are symmetrically fixed on the base 1. The bidirectional screw 62 is rotatably installed between the two columns 61, and a guide rod 631 is also fixed between the two columns 61. Two nut seats 63 are symmetrically threaded on both sides of the bidirectional screw 62, and both nut seats 63 are slidably fitted on the guide rod 631. A driven gear 64 is fixedly fitted in the middle of the bidirectional screw 62. The rack 65 is fixed to the side of the power guide rail 32 through a connecting arm 651, and the rack 65 meshes with the driven gear 64. An L-shaped connecting rod 632 is fixed to the side of each of the two nut seats 63, and a connecting plate 22 is fixed to the top of each of the two connecting rods 632. Two semi-annular brackets 21 are fixed to the side of the connecting plate 22 in a corresponding manner.

[0069] When the push cylinder 31 extends to push the power guide rail 32 and the tray 4 upward, under the fixed connection of the connecting arm 651, the power guide rail 32 drives the rack 65 to move upward synchronously. The upward rack 65 meshes with and drives the driven gear 64, which in turn drives the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 drives the two nut seats 63 to move away from each other. Under the connection of the connecting rod 632 and the connecting plate 22, the two half-ring brackets 21 are driven away from each other. When the power guide rail 32 retracts to drive the tray 4 downward, the driving direction is opposite to the above, which in turn drives the two half-ring brackets 21 to move closer to each other.

[0070] Example 6: Please refer to Figure 2 The difference between this embodiment and embodiment 5 is as follows:

[0071] A bracket 202 is fixed to one side of the mounting frame 201, and an industrial vision camera B23 is fixed to the end of the bracket 202. This camera is used to detect the state of the willow woven barrel falling onto the tray 4. Specifically, the industrial vision camera B23 takes a picture when the willow woven barrel falls onto the tray 4 and uploads the picture to the system. The system processes and analyzes whether the willow woven barrel is tilted. If the willow woven barrel that falls onto the tray 4 is tilted, the controller controls the push cylinder 31 to retract, driving the power guide rail 32, the tray 4, the inner support mechanism 5, and the willow woven barrel to move downward. At the same time, under the linkage of the adjustment mechanism 6, the two semi-circular brackets 21 are driven to move closer to each other. Combined with the semi-circular structure of the semi-circular brackets 21, the two semi-circular brackets 21 that move closer to each other clamp and straighten the willow woven barrel from both sides, ensuring that the willow woven barrel can fall onto the tray 4 in the correct posture. In addition, after the willow woven barrel is straightened, the push cylinder 31 extends again, pushing the tray 4 upward to its original height.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
