Description

Technical Field

[0001] This invention relates to the field of screening device technology, specifically an octagonal screening device based on laser measurement. Background Technology

[0002] As a commonly used spice and industrial raw material, the integrity of star anise directly affects product quality and economic value. Therefore, in the star anise processing process, it is necessary to screen and remove unqualified products that are broken or missing corners. The accurate screening of broken and missing star anise is an important process in the deep processing of star anise and is of great significance to improving the overall quality of star anise products.

[0003] Currently, star anise screening mainly employs manual or traditional mechanical methods. Manual screening relies on operators visually identifying the shape of the star anise and manually picking out broken or missing pieces, resulting in low efficiency, high labor intensity, and susceptibility to human fatigue leading to misjudgments and omissions. Traditional mechanical screening struggles to accurately distinguish between qualified and unqualified products based on the shape and integrity of the star anise's edges, resulting in low screening accuracy. Even with optical detection components, a single clamping and transfer mechanism must complete a series of actions, including clamping, transferring, and recycling, before proceeding to the next round of work, leading to long processing cycles and preventing continuous screening. Furthermore, it is difficult to accurately locate and efficiently process irregularly shaped broken or missing star anise, making it challenging to balance screening accuracy and efficiency.

[0004] Therefore, it is necessary to provide an octagonal screening device based on laser measurement to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an octagonal screening device based on laser measurement. By setting up a laser measuring instrument, parameters such as the shape outline and edge integrity of the octagon can be accurately collected, so as to achieve accurate identification and positioning of broken and missing octagons. This effectively solves the technical problem of the difficulty in accurately screening irregularly shaped octagons, significantly improves screening accuracy, and avoids misjudgment and missed judgment.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an octagonal screening device based on laser measurement, comprising a support frame, two support plates disposed inside the support frame, a robotic arm disposed on one side of the support frame, a laser measuring instrument mounted on the robotic arm, and two clamps. The side walls of the two support plates are movably fitted together, and the two support plates close the top opening of the support frame. A first driving component for driving the two support plates to rotate relative to each other is disposed on the support frame. A support plate is fixedly installed on the side wall of the laser measuring instrument. A second driving component for driving the two clamps to rotate is disposed on the support plate. A negative pressure suction component is installed at the top of the support plate. When the driving component drives the two clamps to rotate, the clamp located above enters the negative pressure suction component.

Two rotating shafts pass through the two drive seats and are fixedly connected to the drive seats. The rotating shafts are rotatably connected to the support frame. The cylinder is arranged vertically and is fixedly connected to the support frame. The output end of the cylinder is fixedly connected to the connecting seat. The connecting seat is connected to the two rotating shafts respectively through two telescopic connectors.

[0008] A further configuration of the present invention is as follows: the telescopic connector includes a connecting cylinder and a sliding column, one end of the sliding column is hinged to the connecting seat, the other end of the sliding column extends into the connecting cylinder, and the sliding column and the connecting cylinder are slidably engaged, and the end of the connecting cylinder away from the sliding column is rotatably connected to the rotating shaft.

[0009] A further configuration of the present invention is as follows: the second drive assembly includes a motor and a rotating base, the motor is fixedly mounted on the support plate, the output end of the motor is fixedly connected to the rotating base, and two clamps are respectively mounted on both ends of the rotating base.

The recycling box is fixedly connected to the top wall of the supporting upright plate. The bottom of the recycling box is open. Elastic baffles are fixedly connected to both sides of the bottom opening of the recycling box. The top of the recycling box is connected to a recycling pipe.

[0011] A further feature of the present invention is that the clamp is provided with two grippers, and air supply channels are provided on both sides of the clamp, with the air outlet of the air supply channel located between the two grippers.

[0012] A further feature of the present invention is that a hopper is fixedly installed on the lower surface of the support frame, and the hopper is connected to the support frame.

[0013] A further provision of the present invention is that a vibrator is fixedly installed on the side wall of the support frame.

[0024] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Please see Figures 1 to 7In this embodiment of the invention, an octagonal screening device based on laser measurement includes a support frame 1, two support plates 3 disposed inside the support frame 1, a robotic arm 4 disposed on one side of the support frame 1, a laser measuring instrument 5 mounted on the robotic arm 4, and two clamps 11. The side walls of the two support plates 3 are movably fitted together, and the two support plates 3 close the top opening of the support frame 1. The support frame 1 is provided with a first driving component for driving the two support plates 3 to rotate relative to each other. The side wall of the laser measuring instrument 5 is fixedly installed with a support plate 8. The support plate 8 is provided with a second driving component for driving the two clamps 11 to rotate. The top of the support plate 8 is installed with a negative pressure suction component. When the driving component drives the two clamps 11 to rotate, the clamp 11 located above enters the negative pressure suction component.

[0026] In practical use, the octagons to be screened are laid flat on the two support plates 3 inside the support frame 1. Then, the laser measuring instrument 5 on the robotic arm 4 accurately detects the octagons on the support plates 3. By collecting parameters such as the shape contour and edge integrity of the octagons, the identification and positioning of broken and missing octagons are completed. Then, the robotic arm 4 drives the clamp 11 to move, so that the lower clamp 11 is aligned with the broken octagon and clamps it. After clamping, the two clamps 11 are driven to rotate synchronously by the drive component 2, realizing the exchange of positions between the two clamps 11. Then, the clamp 11 holding the broken octagon is transferred to the inside of the negative pressure suction component. At this time, the clamp 11 is released from the clamping limit of the broken octagon, and the negative pressure suction generated by the negative pressure suction component is used to transfer the clamp 11 to the inside of the negative pressure suction component. The broken star anise is quickly sucked out and recycled. During this process, another clamp 11 can simultaneously carry out the gripping operation of the next broken star anise, without waiting for the broken star anise to be transferred and recycled, forming a continuous screening operation process. This process is repeated until all broken star anise is completely removed. This solution achieves integrated operation of gripping and recycling broken star anise through the coordinated cooperation of two clamps 11, drive component two and negative pressure suction component. There is no need to set up an additional broken star anise transfer mechanism, which greatly shortens the processing cycle of a single broken star anise and effectively improves screening efficiency. At the same time, the precise positioning method of laser measurement solves the technical problem that broken and missing star anise are difficult to screen efficiently and accurately due to their irregular shape, ensuring screening accuracy and operational stability.

[0027] In this embodiment, preferably, a hopper 2 is fixedly installed on the lower surface of the support frame 1, and the hopper 2 is connected to the support frame 1. After screening, the two support plates 3 are driven to rotate by the drive component 1, so that the qualified octagons on the support plates 3 slide tilted into the support frame 1, and are then discharged in a concentrated manner through the hopper 2. When in use, a receiving container is set below the hopper 2 for unified collection, so as to realize the automated discharge of qualified materials and further improve the operation continuity of the device.

[0028] In this embodiment, preferably, the drive assembly includes a drive seat 13, a rotating shaft 14, a telescopic connector, a connecting seat 17, and a cylinder 18. Two drive seats 13, rotating shafts 14, and telescopic connectors are provided. The two drive seats 13 are arranged parallel to each other and are respectively fixedly connected to the lower surfaces of the two support plates 3. The two rotating shafts 14 pass through the two drive seats 13 respectively and are fixedly connected to the drive seats 13. The rotating shafts 14 are rotatably connected to the support frame 1. The cylinder 18 is vertically arranged and fixedly connected to the support frame 1. The output end of the cylinder 18 is fixedly connected to the connecting seat 17. The connecting seat 17 is connected to the two rotating shafts 14 respectively through two telescopic connectors. The connector includes a connecting cylinder 15 and a sliding column 16. One end of the sliding column 16 is hinged to the connecting seat 17, and the other end of the sliding column 16 extends into the connecting cylinder 15. The sliding column 16 and the connecting cylinder 15 are slidably engaged. The end of the connecting cylinder 15 away from the sliding column 16 is rotatably connected to the rotating shaft 14. When the drive support plate 3 rotates, the output end of the control cylinder 18 retracts to drive the connecting seat 17 to move downward. When the connecting seat 17 moves downward, it drives the rotating shaft 14 to rotate through the telescopic connector. When the rotating shaft 14 rotates, it drives the support plate 3 to rotate through the drive seat 13, so that the octagon on the support plate 3 slides downward. Through the sliding adaptation characteristics of the telescopic connector, the stability of power transmission during the rotation of the rotating shaft 14 is ensured, and the support plate 3 is prevented from jamming.

[0029] In this embodiment, preferably, a vibrator 19 is fixedly installed on the side wall of the support frame 1. When the octagon is laid on the support plate 3, the vibrator 19 is turned on and controlled to work, so that the support plate 3 vibrates slightly. When the support plate 3 vibrates, it drives the octagon on it to vibrate synchronously, which effectively avoids the stacking of octagons causing missed or false detections in laser measurement, and ensures that each octagon can be accurately detected by the laser measuring instrument 5. At the same time, when the support plate 3 rotates and the octagon slides down, the vibrator 19 drives the whole equipment to vibrate slightly, which can break the friction between the octagon and the support plate 3, so that the octagon on the support plate 3 slides down quickly and smoothly, avoiding material residue.

[0030] In this embodiment, preferably, the second driving component includes a motor 9 and a rotating seat 10. The motor 9 is fixedly mounted on the support plate 8, and the output end of the motor 9 is fixedly connected to the rotating seat 10. Two clamps 11 are respectively mounted on both ends of the rotating seat 10. The motor 9 can drive the rotating seat 10 to rotate precisely. When the rotating seat 10 rotates, it drives the two clamps 11 to rotate synchronously along a circular trajectory, realizing the rapid and stable position exchange of the two clamps 11, ensuring the smooth connection between the crushed octagonal transfer and subsequent clamping operations, and improving work efficiency.

[0031] In this embodiment, preferably, the clamp 11 is provided with two grippers 1101. The two grippers 1101 on the clamp 11 can move relative to each other to firmly clamp the octagon. The grippers 1101 are made of flexible material to form a flexible gripper 1101 structure, which can fit the shape of the octagon during the clamping process, avoid damage to the octagon due to excessive clamping force, reduce the loss of qualified materials, and improve the clamping stability of irregularly shaped octagons.

[0032] In this embodiment, preferably, the negative pressure suction assembly includes a recycling box 6, elastic baffles 7, and a recycling pipe 12. The recycling box 6 is fixedly connected to the top wall of the supporting plate 8. The bottom of the recycling box 6 is open, and elastic baffles 7 are fixedly connected to both sides of the bottom opening of the recycling box 6. The top of the recycling box 6 is connected to the recycling pipe 12. The elastic baffles 7 are made of elastic rubber. When the rotating seat 10 drives the two clamps 11 to rotate, the clamps 11 knock open the elastic baffles 7 and enter the recycling box 6. After the clamps 11 are fully inside the recycling box 6, the elastic baffles 7 return to their original position, thus realizing the recycling box... The sealing of the bottom opening 6 ensures a stable negative pressure environment within the recycling box 6. The negative pressure suction assembly is equipped with a negative pressure suction device, which is used to collect the recycled broken star anise. The negative pressure suction device is existing technology and will not be described in detail here. During operation, after the negative pressure pump in the negative pressure suction device starts, a negative pressure gradient is generated in the recycling box 6 through the recycling pipe 12. When the clamp 11 holding the broken star anise enters the recycling box 6 and releases the clamp, the broken star anise moves along the recycling pipe 12 under the action of negative pressure suction for collection and recycling, thus completing the recycling process of the broken star anise.

[0033] In this embodiment, preferably, air supply channels 1102 are provided on both sides of the clamp 11, and the air outlet of the air supply channel 1102 is located between the two grippers 1101. When the negative pressure suction device is suctioning material, the external airflow can enter between the two grippers 1101 through the air supply channel 1102. The airflow acts on the surface of the crushed octagon. On the one hand, it can blow away the crushed octagon that is attached to the gripper 1101 to avoid material residue. On the other hand, it can form an auxiliary airflow, which, together with the negative pressure suction, accelerates the movement of the crushed octagon, further improves the material extraction efficiency, and ensures that the crushed octagon in the recycling box 6 can be completely sucked out.

[0034] Working principle: When this octagonal screening device is working, the octagons to be screened are first laid flat on two fitting support plates 3 inside the support frame 1. The vibrator 19 is turned on to make the support plates 3 vibrate slightly to avoid the stacking of octagons, which would cause missed or false detections in the laser measurement. Then, the robotic arm 4 drives the laser measuring instrument 5 to accurately detect the octagons, collecting parameters such as the shape contour and the integrity of the edges and corners, and completing the identification and positioning of broken and missing octagons. The robotic arm 4 drives the lower clamp 11 to align with and clamp the broken octagon. The drive component 2 drives the two clamps 11 to rotate synchronously to realize the position exchange, transferring the clamp 11 holding the broken octagon to the negative pressure suction component. At the same time, the other clamp 11 can start the next round of clamping, forming a continuous operation.

[0035] In the negative pressure suction assembly, the elastic baffle 7 resets and seals after the clamp 11 enters. The negative pressure suction device generates negative pressure through the recovery pipe 12, and after the clamp 11 is released, the crushed octagon is sucked out and recovered. The air supply channels 1102 on both sides of the clamp 11 introduce airflow to avoid material residue and assist in accelerating the suction. After screening, the drive assembly drives the two support plates 3 to rotate relative to each other, and the vibrator 19 assists the qualified octagon to slide into the support frame 1, and then discharges and collects it through the discharge hopper 2. The whole process realizes the integrated and efficient operation of crushed octagon screening, clamping, recovery and qualified octagon discharge, taking into account both screening accuracy and operation efficiency.
