Description

Technical Field

[0001] This invention relates to the field of automated sorting technology for electronic components, specifically an automated sorting and classification device for chip resistors based on industrial vision inspection. Background Technology

[0002] In automated production processes such as production grading, appearance inspection, defective product rejection, and recycling of surface mount resistors, vibratory feeding and linear vibratory conveyor tracks combined with industrial vision are commonly used to achieve automated sorting. Currently, the mainstream conveyor mechanisms in the industry are mostly fixed-width grooved tracks. The track grooves are precisely machined according to the dimensions of a single resistor specification, resulting in poor equipment versatility. When switching to different specifications of components, it is necessary to completely disassemble and replace the corresponding width of the conveyor track. The changeover process is cumbersome, time-consuming, and requires multiple sets of dedicated track spare parts, leading to high overall operating costs.

[0003] Some equipment adopts an open straight rail structure with adjustable side plates on both sides in an attempt to achieve compatibility with multiple specifications. However, the rail base plate is mostly a fixed structure, while the sorting mechanism needs to open sorting gaps on the rail. This directly disrupts the continuity of the conveyor base plate, causing material jamming and leakage when the material passes through the sorting area. In addition, the traditional rigid lever or air-blowing sorting action has a strong impact, which easily disturbs the continuous flow of materials. The air-blowing method may also cause lightweight chip resistors to fly and turbulent, resulting in insufficient sorting reliability. At present, there is no sorting device in the industry that can meet the needs of high-efficiency, high-precision, and multi-specification universal chip resistor automated sorting.

[0004] Therefore, it is necessary to provide an automated sorting and classification device for chip resistors based on industrial vision inspection to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated sorting and classification device for chip resistors based on industrial vision inspection, comprising a vibrating feeding mechanism, a linear vibrating conveyor track, an industrial vision inspection unit, a chain plate unit, a material recycling and diversion mechanism, and a control system;

[0006] The linear vibrating conveyor track includes a fixed side plate and a movable side plate. Multiple first bottom plate strips are uniformly fixedly arranged at the bottom of the fixed side plate, and multiple second bottom plate strips are uniformly fixedly arranged at the bottom of the movable side plate. The multiple first bottom plate strips and second bottom plate strips slide and interlock with each other to form a continuous and seamless conveyor bottom plate. Multiple sorting notches are opened on the fixed side plate, and a rotating plate is rotatably arranged at the sorting notch.

[0007] The industrial vision inspection unit is located upstream of the sorting gap and is used to identify the specifications, posture and appearance defects of the chip resistors. The control system drives the turntable corresponding to the sorting gap to rotate according to the vision signal, so as to pull the resistors out of the linear vibration conveyor track and transport them to the corresponding material recycling and diversion mechanism.

[0008] Furthermore, as a preferred embodiment, the movable side plate is fixedly provided with a baffle at the position corresponding to the sorting gap. The second bottom plate strip is not provided at the baffle, and the chain plate unit is fixedly installed at the position where the second bottom plate strip should be provided. Two chain plate units are fixedly provided at both ends of the turntable in a centrally symmetrical manner. Multiple chain plate units are used to replace the first bottom plate strip and the second bottom plate strip at the corresponding positions, so that the conveying bottom plate remains continuously flat.

[0009] Furthermore, preferably, the chain plate unit includes:

[0010] The fixing plate has symmetrical mounting grooves on its upper and lower sides;

[0011] A sliding plate is slidably connected to the fixed plate, and a spring is provided between the two. The upper and lower sides of the sliding plate are flush with the bottom surfaces of the two mounting slots, respectively.

[0012] A flexible chain plate covers the outside of the fixed plate and the sliding plate. One end of the flexible chain plate is fixedly connected to one of the mounting slots, and the other end is connected to the other mounting slot via an elastic strap.

[0013] Furthermore, as a preferred embodiment, a slide rail is fixedly provided on the fixing plate;

[0014] An L-shaped support plate is fixedly installed on the sliding plate. The L-shaped support plate slides along the slide rail, and the end of the L-shaped support plate away from the fixed plate protrudes from the outer side of the flexible chain plate.

[0015] Furthermore, as a preferred embodiment, the flexible chain plate is composed of multiple columnar strips that are rotated and connected in sequence. The height of the columnar strips is equal to the depth of the mounting groove, and the outer side of the multiple columnar strips is wrapped with rubber pads. The rubber pads can fill the gap between two adjacent columnar strips and make the outer surface of the flexible chain plate form a continuous and smooth plane.

[0016] Furthermore, as a preferred embodiment, a first permanent magnet is embedded inside the columnar strip, and a second permanent magnet that attracts the first permanent magnet is embedded inside the fixed plate and the sliding plate respectively. Under the combined action of the tension of the elastic strap and the attraction force of the permanent magnet, the flexible chain plate always adheres to the outer surface of the fixed plate and the sliding plate.

[0017] Furthermore, as a preferred embodiment, the material recycling and diversion mechanism includes at least one abnormal posture return port, multiple good product sorting ports and one defective product port, wherein the abnormal posture chip resistors are returned to the vibrating feeding mechanism for cyclic feeding, and good product chip resistors and defective product chip resistors are directly discharged and collected.

[0018] Furthermore, preferably, the single rotation angle of the rotating plate is 180°, and its rotating material-pushing action matches the vibration frequency of the linear vibrating conveyor track.

[0019] Furthermore, as a preferred embodiment, the movable side plate can slide along the width direction of the linear vibrating conveyor track to adjust the width of the conveyor base plate and the overall track width.

[0020] Furthermore, preferably, the thickness of the rotating plate is the same as the thickness of the fixed side plate and the movable side plate, and the outer side of the flexible chain plate fixedly connected to the mounting groove is flush with the conveying surface of the conveying base plate.

[0021] Compared with existing technologies, the present invention provides an automated sorting and classification device for surface mount resistors based on industrial vision inspection, which has the following advantages:

[0022] First, the system adopts a staggered interlocking base plate structure with fixed and movable side plates, which allows for quick adjustment of the conveyor channel width according to different specifications of surface mount resistors. One set of tracks can accommodate multiple specifications of components, eliminating the tedious operation of frequent track replacement, shortening production line changeover time, and reducing spare parts inventory and equipment investment costs. Furthermore, the first and second base plate strips slide and interlock with each other, always maintaining a continuous and seamless conveyor base plate. Combined with the adaptive chain plate unit to fill gaps in the sorting area, the inner wall of the track after adjustment has no breaks, protrusions, or gaps, ensuring that the tiny surface mount resistors do not jam, tilt, tip over, or jump during vibration conveying, significantly improving conveying stability and visual recognition success rate.

[0023] Secondly, the sliding plate can automatically extend and retract with the displacement of the movable side plate under the action of the spring. Combined with the double adhesion of the elastic pull belt and magnetic adsorption, the flexible chain plate always fits tightly against the support surface. Regardless of whether the track is widened or narrowed, it can automatically compensate for the size change and ensure that the conveying surface remains intact and flat. This solves the industry problem of traditional adjustable tracks that are "able to be widened but not stable".

[0024] Third, chain plate units are symmetrically set at both ends of the turntable. A single 180° rotation can complete the material feeding. At the same time, the chain plate unit on the other side is synchronously reset and replenished, so that the conveyor base plate always maintains a continuous structure during the sorting operation, without interrupting the material flow, realizing high-speed, uninterrupted automated sorting, and greatly improving the overall sorting efficiency.

[0025] Fourth, mechanical rotary feeding replaces high-pressure air blowing, resulting in a gentle feeding action without impact or turbulence. This prevents lightweight materials from scattering or flipping, making the material flow more orderly, improving sorting accuracy, and making the equipment quieter and more environmentally friendly.

[0026] Fifth, an L-shaped support plate protruding from the outside of the flexible chain plate is set, which preferentially abuts against the movable side plate, so that a gap is maintained between the chain plate and the side plate. During the width adjustment and rotation of the rotating plate, there is no direct contact, friction, or squeezing and jamming. The mechanism runs more smoothly, has higher stability and less wear in the long term. Attached Figure Description

[0035] Please see Figures 1 to 7In this embodiment of the invention, the automated sorting and classification device for chip resistors based on industrial vision inspection includes a vibrating feeding mechanism 1, a linear vibrating conveyor track 2, an industrial vision inspection unit, a chain plate unit 3, a material recycling and diversion mechanism, and a control system. The vibrating feeding mechanism 1 adopts a vibrating plate structure to arrange the randomly stacked chip resistors in an orderly manner and transport them to the entrance of the linear vibrating conveyor track 2. The bottom of the linear vibrating conveyor track 2 is equipped with a linear vibrator, which drives the chip resistors to slide smoothly along the length of the track through high-frequency micro-amplitude vibration.

[0036] In this embodiment, the linear vibration conveying track 2 includes a fixed side plate 21 and a movable side plate 22. The bottom of the fixed side plate 21 is uniformly fixed with a plurality of first base plate strips 211, and the bottom of the movable side plate 22 is uniformly fixed with a plurality of second base plate strips 221. The first base plate strips 211 and the second base plate strips 221 slide and engage with each other to form a continuous and seamless conveying base plate. The movable side plate 22 can slide and move along the width direction of the track to realize the overall width adjustment of the track to adapt to the conveying requirements of various conventional chip resistors. After adjustment, it can be locked to ensure that it does not loosen or shift during vibration conveying.

[0037] In this embodiment, the fixed side plate 21 has multiple sorting notches 212 sequentially opened along the material conveying direction. Each sorting notch 212 is rotatably equipped with a rotating plate 23. The rotating plate 23 is driven by the control system to achieve step rotation, with a single rotation angle of 180°. Its rotation action is synchronously matched with the vibration frequency of the linear vibrating conveying track 2, which ensures reliable material feeding without disrupting the continuous material conveying rhythm. The movable side plate 22 has a baffle 222 integrally formed at the position corresponding to the sorting notch 212. The baffle 222 area does not have a second bottom plate strip 221, and the chain plate unit 3 is fixedly installed at the original installation position of the second bottom plate strip 221. The two ends of the rotating plate 23 are symmetrically fixed with their own rotation center as the center of symmetry. All chain plate units 3 together replace the missing first bottom plate strip 211 and second bottom plate strip 221 in the sorting area, so that the conveying bottom plate remains continuous and flat in the sorting area, avoiding jamming, tipping or jumping of the chip resistor during the conveying process.

[0038] In this embodiment, the chain plate unit 3 includes a fixed plate 31, a sliding plate 32, a flexible chain plate 33, and an elastic pull belt 34. The fixed plate 31 has symmetrical mounting grooves 311 on its upper and lower sides. The sliding plate 32 slides with the fixed plate 31, and a spring 321 is provided between them. The spring 321 always provides an outward pushing force to the sliding plate 32, so that the overall length of the chain plate unit 3 can adaptively expand and contract with the change of track width. The upper and lower sides of the sliding plate 32 are flush with the bottom surfaces of the two mounting grooves 311, ensuring a smooth transition of the contact surface of the flexible chain plate 33. A slide rail 312 is fixedly installed on the fixed plate 31, and an L-shaped support plate 322 is fixedly installed on the sliding plate 32. The L-shaped support plate 322 slides along the slide rail 312, and its end away from the fixed plate 31 protrudes out of the outer side of the flexible chain plate 33 for abutting with the movable side plate 22.

[0039] Furthermore, the flexible chain plate 33 covers the outside of the fixed plate 31 and the sliding plate 32. One end of the flexible chain plate 33 is fixedly connected to one of the mounting grooves 311, and the other end is connected to the other mounting groove 311 through an elastic strap 34. The elastic strap 34 continuously provides tension, keeping the flexible chain plate 33 in a taut state at all times. The flexible chain plate 33 is composed of multiple columnar bars 331 hinged together in sequence. The columnar bars 331 are cylindrical rods made of stainless steel or hard alloy, with a diameter of 0.6mm to 1mm. While ensuring sufficient structural rigidity, it also takes into account the need for flexible bending, and can adapt to the deformation requirements caused by track width adjustment and rotation of the rotating plate 23; the diameter of the columnar strip 331 is consistent with the depth of the mounting groove 311, so that the outer surface of the flexible chain plate 33 is flush with the conveying base plate; multiple columnar strips 331 are wrapped with rubber pads 332 on the outside, and the rubber pads 332 can fill the gap between adjacent columnar strips 331, so that the outer surface of the flexible chain plate 33 forms a continuous and smooth plane, further ensuring that the material does not get stuck or curl up during the vibration conveying process.

[0040] To ensure that the flexible chain plate 33 remains flat and fitted during extension, contraction, and rotation, a first permanent magnet is embedded axially inside the columnar strip 331, while a second permanent magnet that attracts the first permanent magnet is embedded inside the fixed plate 31 and the sliding plate 32, respectively. Under the combined action of the tension of the elastic belt 34 and the attraction force of the permanent magnet, the flexible chain plate 33 remains tightly fitted to the outer surfaces of the fixed plate 31 and the sliding plate 32, without arching, warping, or partial detachment, further improving the continuity and stability of the conveying surface.

[0041] It should be noted that the end of the L-shaped support plate 322 away from the fixed plate 31 protrudes outward from the flexible chain plate 33, so that when the L-shaped support plate 322 abuts against the movable side plate 22, a gap is maintained between the flexible chain plate 33 and the movable side plate 22, avoiding direct frictional contact between the flexible chain plate 33 and the movable side plate 22; during the track width adjustment process, the flexible chain plate 33 can adaptively slide along the outside of the fixed plate 31 and the sliding plate 32 under the action of the elastic pull belt 34, always keeping the conveyor base plate flat; when the rotating plate 23 rotates and drives the chain plate unit 3 on it to rotate synchronously, the L-shaped support plate 322 still preferentially contacts the movable side plate 22 and pushes the sliding plate 32 to extend and retract. The sliding plate 32 completes the width adaptation under the joint action of the spring 321 and the L-shaped support plate 322, while the flexible chain plate 33 is synchronously tensioned and adjusted under the cooperation of the elastic pull belt 34, avoiding the flexible chain plate 33 directly abutting against the movable side plate 22 and causing jamming, wear or deformation.

[0042] In this embodiment, the thickness of the rotating plate 23 is the same as that of the fixed side plate 21 and the movable side plate 22. The outer side of the flexible chain plate 33 and the fixed end of the mounting groove 311 are flush with the conveying base plate, so that the inner wall of the entire conveying channel is without steps or breaks, and the material is conveyed smoothly and without obstruction.

[0043] Furthermore, the widths of the first base plate strip 211, the second base plate strip 221, and the chain plate unit 3 are all much smaller than the width of the chip resistor along the transmission direction. This ensures that when the rotating plate 23 rotates and causes the corresponding chain plate unit 3 to detach from the conveying base plate, it will not interfere with the conveying of the chip resistor at the adjacent position. At the same time, the single rotation angle of the rotating plate 23 is designed to be 180°, and its rotating material-pushing action matches the vibration frequency of the linear vibrating conveying track 2. This ensures that when the rotating plate 23 rotates and causes one side of the chain plate unit 3 to push the chip resistor out of the track, the other side of the chain plate unit 3 rotates synchronously and re-engages with the conveying base plate, so that the conveying base plate always maintains a complete and continuous structure, realizing an uninterrupted operation mode of conveying and sorting simultaneously, and greatly improving the sorting efficiency of the chip resistor.

[0044] In this embodiment, the industrial vision inspection unit is arranged upstream of the sorting gap 212 to collect image information of the chip resistors in real time, identify their specifications, dimensions, orientation, appearance damage, printing defects, and other features, and transmit the identification signals to the control system. The material recycling and diversion mechanism includes at least one abnormal posture return port, multiple good product sorting ports, and one defective product port. Materials with abnormal posture or unclear identification are returned to the vibrating feeding mechanism 1 through the return port for re-sorting and secondary inspection. Qualified good products are collected in the corresponding good product sorting ports according to their resistance, accuracy, and size specifications. Defective products with appearance damage, out-of-tolerance dimensions, or unqualified performance are collected in the defective product port and are not recycled.

[0045] In summary, this invention employs a staggered, interlocking base plate structure with fixed and movable side plates. This allows for rapid adjustment of the conveyor channel width to accommodate different specifications of surface mount resistors. One track can accommodate multiple component sizes, eliminating the tedious operation of frequent track changes, shortening production line changeover time, and reducing spare parts inventory and equipment investment costs. Furthermore, the first and second base plate strips slide and interlock, maintaining a continuous and seamless conveyor base. The adaptive chain plate unit fills gaps in the sorting area, ensuring no breaks, protrusions, or gaps on the inner wall of the track after adjustment. This prevents the tiny surface mount resistors from jamming, warping, tipping over, or jumping during vibration conveying, significantly improving conveying stability and visual recognition success rate. The sliding plate automatically extends and retracts with the displacement of the movable side plate under spring action. Combined with the double adhesion of elastic straps and magnetic adsorption, the flexible chain plate always maintains a tight fit with the support surface, automatically compensating for dimensional changes regardless of track width adjustment. The design ensures a continuously intact and flat conveyor surface, solving the industry problem of traditional adjustable tracks being "adjustable in width but not stable." Symmetrical chain plate units are set at both ends of the turntable, allowing material to be fed in a single 180° rotation. Simultaneously, the chain plate unit on the other side resets and fills the gap, ensuring the conveyor base plate maintains a continuous structure during sorting, preventing interruption of material flow and achieving high-speed, uninterrupted automated sorting, significantly improving overall sorting efficiency. Mechanical rotation replaces high-pressure air blowing, resulting in a gentle, impact-free, and turbulent feeding action, preventing the scattering of lightweight materials and tilting. This leads to a more orderly material flow, higher sorting accuracy, and quieter, more environmentally friendly equipment operation. An L-shaped support plate protruding from the outer side of the flexible chain plate preferentially abuts against the movable side plate, maintaining a gap between the chain plate and the side plate. This prevents direct contact, friction, and jamming during width adjustment and turntable rotation, resulting in smoother mechanism operation, higher long-term stability, and less wear.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
