Description

Technical Field

[0001] This utility model relates to the technical field of workpiece collection systems, and more specifically, to a workpiece sorting and inspection system. Background Technology

[0002] Magnets are generally manufactured using powder metallurgy, and then ground after production. Grinding is the most common and widely used machining process, and most workpieces' outer surfaces or corners need to be ground to the desired shape. To improve efficiency, the workpiece is usually first processed into a long strip of magnet, and then the strip is cut into segments according to the required length. To further improve cutting efficiency, multiple magnets are often stacked and cut simultaneously. Glue is applied to adjacent magnets during stacking to prevent them from shifting during cutting. However, this method also introduces a problem: glue residue remains on the outer wall of the cut magnets. Therefore, glue removal is necessary after cutting. A commonly used method is to place the cut workpiece in a glue removal drum. Heating components are installed on the side wall of the drum, and polishing abrasive particles are placed inside. These abrasive particles prevent chipping during workpiece turnover and polish the edges and corners.

[0003] After the workpieces are degummed and polished, they need to be bagged. In the current technology, bagging is usually done manually. Before bagging, the shape of the workpieces needs to be observed. If the workpieces have obvious chipped corners, they are put into the waste box for scrap. This manual sorting and bagging method is not only inefficient, but also leaves some dust particles on the surface of the workpieces after they come out of the degumming system. If they are not dusted, direct packaging will affect the performance of the workpieces to some extent. Summary of the Invention

[0004] To overcome at least one of the defects in the prior art, this utility model provides a workpiece sub-packaging and inspection system that can realize automatic dust removal, shape screening and automatic sub-packaging of workpieces. The entire process does not require human intervention, saving labor costs and improving work efficiency.

[0005] The technical solution adopted by this utility model is to provide a workpiece sorting and inspection system: including a main frame, on which a feeding mechanism, a dust removal mechanism, an inspection and sieving mechanism, and a sorting mechanism are arranged sequentially along its length. A vibrating plate is also provided between the feeding mechanism and the dust removal mechanism. The vibrating plate is used to receive the workpieces conveyed by the feeding mechanism and output them one by one to the inlet end of the dust removal mechanism in a set direction. The outlet end of the dust removal mechanism is connected to the inlet end of the inspection and sieving mechanism, and the outlet end of the inspection and sieving mechanism is connected to the inlet end of the sorting mechanism. The inspection and sieving mechanism is used to detect whether the shape of the workpiece is qualified, and qualified workpieces can be conveyed to the inlet end of the sorting mechanism. Unqualified products can be automatically collected into a waste box. The sorting mechanism is used to sort the qualified workpieces one by one into different packaging bags.

[0006] Compared with the prior art, the workpiece sub-assembly and inspection system of this utility model has the following advantages:

[0007] This utility model's workpiece sorting and inspection system is a specialized system used to automatically separate workpieces after degumming and polishing from the polishing particles. The separated workpieces are then conveyed to a vibratory feeder, where they are arranged one by one at a set angle and output to a dust removal mechanism. This allows for simultaneous dust removal by roller brushes on both sides of the workpiece as it moves. Furthermore, after dust removal, the workpieces undergo automatic shape inspection by a screening and sorting mechanism. If the workpiece shape does not meet the requirements, the system automatically sorts the defective products into a waste bin, while the qualified products continue to be conveyed to the sorting and packaging mechanism, ultimately achieving bagged packaging of the workpieces. The entire process requires no manual intervention, effectively improving work efficiency.

[0008] Furthermore, the feeding mechanism includes a first mounting frame and a conveyor belt mounted on the first mounting frame. The first mounting frame is vertically and elastically connected to the main frame, and a vibrating motor that drives it to shake up and down is also connected to the first mounting frame. The outlet end of the conveyor belt extends to the feed port of the vibrating plate.

[0009] Furthermore, the feeding mechanism also includes a hopper, and a collection box is provided on the main frame. The bottom of the hopper has a sand leakage channel that allows sand particles to pass through only, and the sand leakage channel extends to the collection box. The hopper is equipped with an upwardly inclined feeding conveyor belt for transferring workpieces to the inlet end of the conveyor belt.

[0010] As an improvement, the first mounting frame is obliquely upward along the conveying direction of the workpiece, the conveyor belt is parallel to the base plate of the first mounting frame, and the main frame is also provided with a dispersing roller brush extending along its width direction and a dispersing roller brush motor for driving the roller brush to rotate. The dispersing roller brush is located above the conveyor belt, and a material passage for the workpiece to pass through is left between the lower end face of the dispersing roller brush and the upper end face of the conveyor belt. The height of the material passage is greater than the thickness of the workpiece and less than twice the thickness of the workpiece.

[0011] In a further improvement, the outlet end of the conveyor belt is also connected to an air knife assembly that is inclined downwards, and the air outlet of the air knife assembly faces the conveyor belt.

[0012] Furthermore, the dust removal mechanism includes a second mounting frame and a dust removal conveyor belt. The second mounting frame is slidably provided with two sliding plates and a drive assembly for driving the two sliding plates to slide up and down. Each of the two sliding plates is connected to a dust removal motor, and each of the vertically downward output shafts of the two dust removal motors is connected to a dust removal roller brush. The outer walls of the material conveyor belt on both sides are respectively provided with arc-shaped clearance grooves for accommodating the dust removal roller brushes. The bottom of each of the clearance grooves is provided with a connecting hole, and the opposite sides of the two dust removal roller brushes pass through the connecting holes and are attached to the two side walls of the workpiece.

[0013] In a further improvement, the central axes of the two dust-removing rollers are staggered along the conveying direction of the workpiece.

[0014] Furthermore, the detection and sorting mechanism includes a feeding conveyor belt assembly, a vision inspection assembly, and a pushing assembly. One end of the feeding conveyor belt assembly extends to the outlet end of the dust removal mechanism, and the other end extends to the inlet end of the packaging mechanism. The vision inspection assembly is connected to the main frame, and the camera of the vision inspection assembly is located above the feeding conveyor belt assembly. When the image of the workpiece captured by the camera does not match the image stored in the system, the pushing assembly is used to push the workpiece into the waste box.

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figures 1-5As shown in the figure, this application discloses a workpiece sorting and inspection system, including a main frame 1. The main frame 1 is provided with a feeding mechanism, a dust removal mechanism, an inspection and sieving mechanism, and a sorting mechanism 23 in sequence along its length. A vibrating plate 2 is provided between the feeding mechanism and the dust removal mechanism. The vibrating plate 2 is used to receive the workpieces conveyed by the feeding mechanism and output them one by one to the inlet end of the dust removal mechanism in a set direction. The outlet end of the dust removal mechanism is connected to the inlet end of the inspection and sieving mechanism. The dust removal mechanism is used to remove dust from the workpieces. The outlet end of the inspection and sieving mechanism is connected to the inlet end of the sorting mechanism 23. The inspection and sieving mechanism is used to detect whether the shape of the workpiece is qualified. Qualified workpieces can be conveyed to the inlet end of the sorting mechanism 23, and unqualified products can be automatically collected into the waste box 3. The sorting mechanism 23 is used to sort the qualified workpieces one by one into different packaging bags.

[0027] Specifically, in this embodiment, see Appendix Figure 2 The feeding mechanism includes a first mounting frame 4 and a conveyor belt 5 mounted on the first mounting frame 4. The first mounting frame 4 is vertically and elastically connected to the main frame 1, and a vibrating motor 6 is also connected to the first mounting frame 4 to drive it to vibrate up and down. The outlet end of the conveyor belt 5 extends to the feed inlet of the vibrating plate 2. A collection box 7 located below the conveyor belt 5 is also connected to the main frame 1. When the mixture of workpiece and polishing particles is conveyed to the feeding mechanism, with the operation of the conveyor belt 5 and the up and down vibration of the entire first mounting frame 4, the workpiece and polishing particles can be fully separated. The workpiece continues to move to the vibrating plate 2 under the driving action of the conveyor belt 5, while the polishing particles pass through the mesh of the conveyor belt 5 and are collected in the collection box 7. They can then be put back into the degumming roller to assist in degumming and polishing.

[0028] On the other hand, see Appendix. Figure 2 The aforementioned feeding mechanism also includes a hopper 8, with a sand-leaking channel at the bottom for sand particles to pass through, extending to a collection box 7. The hopper 8 contains an upwardly inclined feeding conveyor belt for transferring workpieces to the inlet of the conveyor belt 5. With this added structure, the mixture of workpieces and polishing particles from the degumming device can be directly fed into the hopper 8. Due to the sand-leaking channel at its bottom, most of the polishing particles are actually recycled into the collection box 7. A small portion of the polishing particles, after being fed onto the conveyor belt 5 along with the workpieces, will be completely separated from the workpieces by the vibration motor 6 and then fall back into the collection box 7. In this embodiment, preferably, see attached... Figure 1 The bottom of the collection box 7 is equipped with rollers and is a movable structure. A receiving cavity is set below the corresponding position of the main frame 1. When in use, the collection box 7 is positioned in the receiving cavity. When the grinding particles in the collection box 7 reach a certain capacity, it can be moved to the glue removal equipment accessory, and then the grinding particles are returned to the glue removal roller by manual or automatic feeding mechanism.

[0029] More specifically, in this embodiment, the first mounting frame 4 is obliquely upward along the conveying direction of the workpiece, and the conveyor belt 5 is parallel to the base plate of the first mounting frame 4, that is, the conveyor belt 5 is also obliquely upward, which makes it easier to separate the workpiece from the polishing particles; and a dispersing roller brush 9 extending along its width direction and a dispersing roller brush motor 10 for driving the roller brush to rotate are also provided on the main frame 1, and the dispersing roller brush 9 is located above the conveyor belt 5. A material passage for the workpiece to pass through is left between the lower end face of the dispersing roller brush 9 and the upper end face of the conveyor belt 5. The height of the material passage is greater than the thickness of the workpiece but less than twice the thickness of the workpiece. In this structure, the dispersing roller brush 9 can beat the workpiece on the conveyor belt 5 to prevent multiple workpieces from sticking together, and ensure that the workpiece can only pass through the material passage in a single layer, which facilitates the subsequent vibratory plate 2 to arrange the workpiece at a set angle and output it to the dust removal mechanism, ensuring that each workpiece can enter the packaging mechanism 23 after dust removal. In addition, vertical supports 24 are respectively provided on both sides of the first mounting frame 4 on the top plate of the main frame 1. The two ends of the dispersing roller brush 9 are rotatably connected to the two vertical supports 24 respectively, and the dispersing roller brush motor 10 is connected to one of the vertical supports 24.

[0030] In the above structure, an improved version is provided, in which an air knife assembly 11 is connected at the outlet end of the conveyor belt 5, which is inclined downwards and the air outlet of the air knife assembly 11 faces the conveyor belt 5, so that the workpiece is separated from the polishing particles more thoroughly.

[0031] Additionally, in this embodiment, see Appendix Figure 3 , 4 5. The dust removal mechanism includes a second mounting frame 12 and a dust removal conveyor belt. The second mounting frame 12 is slidably provided with two slide plates 13 and a drive assembly for driving the two slide plates 13 to slide up and down. In this structure, the two slide plates 13 are slidably connected to the second mounting frame 12 through a linear guide rail to ensure smooth and reliable sliding. The drive assembly is a servo motor 20 that drives a screw mechanism to drive the slide plates 13 to rise and fall, and the drive is smooth and reliable.

[0032] More specifically, in the above structure, two horizontally extending dovetail groove support plates 22 are also provided on the second mounting bracket 12. Two sliding plates 13 and two drive components are respectively connected to the slides of the two dovetail groove support plates 22. By adjusting the corresponding dovetail groove support plates 22, the distance between the two dust removal roller brushes 15 can be adjusted horizontally, thereby better adapting to dust removal of workpieces of different thicknesses and improving versatility.

[0033] Additionally, anti-vibration springs 21 are connected between the two slide plates 13 and the second mounting bracket 12. Dust removal motors 14 are connected to both slide plates 13, and dust removal rollers 15 are connected to the vertically downward output shafts of both dust removal motors 14. Arc-shaped clearance grooves 16 for accommodating the dust removal rollers 15 are respectively provided on the outer walls of the material conveyor baffles on both sides of the dust removal conveyor belt. The bottom of each clearance groove 16 has a connecting hole, and the opposite sides of the two dust removal rollers 15 pass through the connecting hole and adhere to the two side walls of the workpiece. In this structure, the central axes of the two dust removal rollers 15 are staggered along the conveying direction of the workpiece, effectively ensuring sufficient dust removal on both sides of the workpiece while preventing the workpiece from being jammed by the two dust removal rollers 15 and thus affecting work efficiency. Furthermore, in the above structure, the two dust removal rollers can also move up and down, ensuring full contact between the two side walls of the workpiece in the height direction and the dust removal rollers 15 for dust removal. Preferably, the dust removal rollers 15 are wire brushes.

[0034] On the other hand, the inspection and screening mechanism includes a feeding conveyor belt assembly 17, a vision inspection assembly 18, and a pushing assembly 19. One end of the feeding conveyor belt assembly 17 extends to the outlet of the dust removal mechanism, and the other end extends to the inlet of the packaging mechanism 23. The vision inspection assembly 18 is connected to the main frame 1, and the camera of the vision inspection assembly 18 is located above the feeding conveyor belt assembly 17. When the image of the workpiece captured by the camera does not match the image stored in the system, the pushing assembly 19 pushes the workpiece into the waste box 3. The pushing assembly 19 includes a push rod and a push rod drive cylinder, and the push rod drive cylinder is electrically connected to the system controller, and the camera is also electrically connected to the system controller. The waste box 3 is connected to the main frame 1 on the side opposite to the push rod. When the system detects defects such as corner dents in the workpiece and determines that the shape is unqualified, the push rod drive cylinder drives the push rod to extend, pushing the workpiece that has been moved on the feeding conveyor belt assembly 17 into the waste box 3, thereby realizing automatic screening of workpieces and improving work efficiency.

[0035] In addition, the qualified workpieces are conveyed to the packaging mechanism 23. In this embodiment, the packaging mechanism 23 is a rotary packaging mechanism 23, which is used to package the qualified workpieces one by one into the corresponding packaging bags. The rotary packaging mechanism 23 in this structure is an existing structure. The applicant has relevant patents. For details, please refer to the automatic rotary bag-splitting device disclosed in patent CN219382998U. It will not be elaborated here.
