Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and in particular to a feeding device with a cleaning effect for processing automotive parts. Background Technology

[0002] In automotive parts manufacturing, cylindrical parts such as drive shafts, steering columns, piston rods, valve cores, and guide pillars account for a significant proportion. After these parts undergo final finishing processes such as turning, grinding, drilling, and tapping, a large amount of microscopic metal shavings, abrasive particles, and residual coolant mixture will adhere to their surfaces, inner holes, threaded grooves, and relief grooves.

[0003] The current standard production process is as follows: after parts are machined on a machine tool, they are directly transported by a robotic arm or inclined slide to the unloading conveyor line (such as a conveyor belt, roller, or basket), and then sent to a cleaning machine for centralized cleaning, or directly enter subsequent stages such as assembly, inspection, and packaging. However, the critical moment between the completion of machining and the start of unloading is precisely the blind spot and the most effective time for cleaning intervention. The existing process has significant defects in this area. If the "fresh" debris after machining is not removed at the point of generation, it will be crushed and embedded in the micro-dents or threads on the surface of the parts due to residual cutting fluid or its own plasticity during the vibration, rolling, and collision during the conveying process, forming "solidified contamination." Subsequent cleaning requires extremely strong processes, such as high-pressure spraying and ultrasonic cleaning, to remove it, and may damage the finished surface. Moreover, without preliminary cleaning during unloading, a large amount of debris will concentrate in the central cleaning machine during subsequent cleaning, which will quickly contaminate the cleaning fluid, clog the filter, and increase maintenance frequency and costs. Therefore, a feeding device with cleaning effect for automotive parts processing is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device with a cleaning effect for processing automotive parts includes a processing table, a suspension assembly at the top of the processing table, a guide frame assembly on the left side of the suspension assembly, a discharge table on the right side of the suspension assembly, a vibrating conveyor assembly for continuous feeding inside the suspension assembly, and an air jet for blowing away debris at the top of the suspension assembly. The suspension assembly includes a side plate, the bottom end of which is movably mounted on the top of the processing table via a spring bolt assembly B. Support blocks are equidistantly arranged on the top of the side plate, and a rubber pad is installed between the processing table and the side plate. The vibrating conveying assembly includes an inner plate fixed to the inner wall of the side panel. A beam plate is connected to the top of the inner plate. Support shafts are rotatably installed on both ends of the beam plate. Movable support plates are connected to the inner ends of the two support shafts. The two movable support plates are connected and fixed to each other by a through shaft. The through shaft passes through the inside of the support platform through a through hole and is movably connected to the support platform. Adjacent support platforms are connected and fixed to each other by a connecting plate. A driving device is provided after one end of one of the support shafts passes through the side panel.

[0006] Preferably, the drive device includes a variable frequency motor, and the variable frequency motor is mounted on the side of the side plate via a support plate. The shaft end of the variable frequency motor is provided with a pulley assembly, and the pulley assembly consists of a connecting belt between two pulleys and a drive pulley. One pulley shaft end is connected and fixed to the support shaft end, and the other pulley shaft end is connected and fixed to the variable frequency motor shaft end.

[0007] Preferably, the side uprights are symmetrically connected to two external support rods on both sides, and the external support rods are movably mounted on the top of the processing table via spring bolt group A. The suspension group includes the side uprights, the bottom of which is movably mounted on the top of the processing table via spring bolt group B, giving it a certain elastic vibration capability, which helps to shake off debris from the surface of the parts during transportation. The two external support rods symmetrically connected to both sides of the side uprights, and the movable mounting of the external support rods via spring bolt group A, further enhance the stability and vibration resistance of the overall structure. The top of the side uprights is provided with equidistant support blocks for temporarily supporting the columnar parts being transported.

[0008] Preferably, the guide frame assembly includes a hollow frame plate fixed to the left side of the side upright plate, and the right side of the hollow frame plate has a groove for the external support rod to be adapted. The hollow frame plate has a baffle end on its side. The guide frame assembly includes a hollow frame plate fixed to the left side of the side upright plate, and the right side of the plate has a groove for the external support rod to be adapted, so as to ensure accurate structural connection.

[0009] Preferably, the side of the hollow frame plate is bolted to a fixed plate, and a movable shaft is rotatably mounted on the inner side of the top of the fixed plate through a through hole. A support spring is welded to the end of the movable shaft, and the end of the support spring is fixed to the inner end face of the side support plate. The side support plate is fixed to the surface of the fixed plate, and the cross-section of the side support plate is L-shaped. Cleaning brushes are arranged at the bottom of the movable shaft. The side of the hollow frame plate is bolted to the fixed plate, and the movable shaft is rotatably mounted on the fixed plate. The cleaning brushes are arranged at the bottom of the movable shaft. The movable shaft is connected to the side support plate through the support spring, so that the cleaning brushes have a certain elastic pressure, which can clean the parts as they roll over, and at the same time play a role in straightening and guiding.

[0010] Preferably, the top of the sweeping brush is a straight plate, and the bottom of the sweeping brush is a bristle end, with the bottom edge of the bristle end of the sweeping brush having an overall curved structure design.

[0011] Preferably, the top of the support platform has a placement groove, and the inner sides of the placement groove are set at an independent inclined angle. The bottom of the inner wall of the placement groove of the support platform has a rounded structure design. The bottom of the support platform is made of rigid PVC material, and the top of the support platform is made of hard rubber material. Adjacent support platforms are fixed by connecting plates to form a continuous conveying platform. One of the support shafts passes through the side uprights and is connected to the drive device. The drive device includes a variable frequency motor and a pulley set to realize the cyclic swing of the support platform to complete the picking and transferring of parts. The top of the support platform has a placement groove with an inclined angle design on the inner sides and a rounded bottom, which ensures the stability of the parts and facilitates the sliding of debris. The bottom is made of rigid PVC material, which is wear-resistant and lightweight. The top is made of hard rubber material, which is non-slip and protects the surface of the parts.

[0012] Preferably, the unloading platform is fixed to the right side of the processing frame by bolts. A groove for supporting the movement of the platform is provided at the center of the left side of the unloading platform. A gap groove for matching the outer support rod is provided on the left side of the unloading platform near the supporting platform. The top surface of the unloading platform is designed with a slope from left to right, with the left side higher than the right side. The unloading platform is fixed to the right side of the processing frame, and the slope from left to right facilitates the automatic sliding of the parts to the next work position. The groove for supporting the movement of the platform and the gap groove for matching the outer support rod on its left side ensure that there is no interference during the movement.

[0013] Preferably, the air jet component includes two limiting side plates fixed to the outer surfaces of two side uprights. Supports are bolted to the top left and right sides of the limiting side plates, and an air jet pipe is rotatably installed inside the support through a through hole. A connecting pipe is connected to both ends of the air jet pipe, and an air pump is installed at the end of the connecting pipe. A locking screw is screwed into the top of the support through a threaded hole. Several sets of air nozzles are equidistantly arranged on the inner end of the air jet pipe. The middle nozzle of each set of air nozzles is designed to be oppositely inclined, with the nozzles tilted towards the adjacent support platform. The air jet pipe is connected to the air pump at both ends, and several sets of symmetrically inclined air nozzles are installed inside the air jet pipe. The nozzle direction is precisely aligned with the part position on the support platform. By rotating both ends of the air jet pipe and fixing it with the locking screw, the angle of the air jet pipe can be adjusted to adapt to different part sizes. The high-pressure airflow can thoroughly blow away debris and dust from the surface of the parts, achieving non-contact and efficient cleaning.

[0014] The present invention has at least the following beneficial effects: 1. This invention integrates air jet cleaning and brushing structures during the feeding process, enabling proactive cleaning during the golden window period when columnar parts are just finished processing and before debris has solidified. The air jet component performs directional high-pressure blowing on the surface of the parts, and the cleaning brush in the guide frame assembly brushes the surface of the parts. This effectively removes metal debris and coolant residues adhering to the surface of the parts, thread grooves and other microstructures, preventing them from embedding into the surface due to vibration and rolling during the conveying process, thus reducing the difficulty of subsequent cleaning and the risk of damage.

[0015] 2. The vibrating conveyor assembly uses a variable frequency motor to drive the support platform in a cyclical motion, achieving continuous and stable conveying of parts. The support platform is made of hard rubber, which has good cushioning and anti-slip properties. Combined with the arc-shaped placement groove at the top, it can stably support various columnar parts. At the same time, the suspension assembly achieves elastic support through spring bolt group A and spring bolt group B, which can generate slight vibration during the conveying process, further promoting the shedding of debris and improving the cleaning effect.

[0016] 3. This device can be seamlessly integrated with existing machine tools and conveyor belts to achieve continuous operation of processing, cleaning and unloading, reducing manual intervention and transfer links. The cleaning process is completed simultaneously during feeding, which not only reduces the burden on the central cleaning system and extends the service life of the cleaning fluid and filter screen, but also reduces rework and scrap rates caused by incomplete cleaning, thereby significantly improving production efficiency and product quality and reducing overall operation and maintenance costs.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] Reference Figure 1-8 A feeding device with a cleaning effect for processing automotive parts includes a processing table 1, a suspension assembly 2 at the top of the processing table 1, a guide frame assembly 3 on the left side of the suspension assembly 2, a discharge table 4 on the right side of the suspension assembly 2, a vibrating conveyor assembly 5 for continuous feeding on the inner side of the suspension assembly 2, and an air jet 6 for blowing away debris at the top of the suspension assembly 2. The suspension assembly 2 includes a side plate 21. The bottom end of the side plate 21 is movably mounted on the top of the processing table 1 via a spring bolt assembly B24. Support blocks are arranged at equal intervals on the top of the side plate 21. A rubber pad 25 is installed between the processing table 1 and the side plate 21. The vibrating conveyor assembly 5 includes an inner plate 51 fixed to the inner wall of the side plate 21. A beam plate 52 is connected to the top of the inner plate 51. Support shafts 53 are rotatably installed on both ends of the beam plate 52. Movable support plates 56 are connected to the inner ends of the two support shafts 53. The two movable support plates 56 are connected and fixed to each other by a through shaft 59. The through shaft 59 passes through the inside of the support plate 57 through a through hole and is movably connected to the support plate 57. The two adjacent support plates 57 are connected and fixed to each other by a connecting plate 58. One end of one of the support shafts 53 passes through the side plate 21 and is equipped with a drive device.

[0022] The drive unit includes a variable frequency motor 55, which is mounted on the side of the side plate 21 via a support plate. A pulley assembly 54 is provided on the shaft end of the variable frequency motor 55, which consists of a belt connecting two pulleys and a drive pulley. One pulley shaft end is connected and fixed to the shaft end of the support shaft 53, and the other pulley shaft end is connected and fixed to the shaft end of the variable frequency motor 55.

[0023] Two external support rods 22 are symmetrically connected on the left and right sides of the side plate 21, and the external support rods 22 are movably installed on the top of the processing table 1 through spring bolt group A23.

[0024] The guide frame assembly 3 includes a hollow frame plate 31 fixed to the left side of the side upright plate 21. The hollow frame plate 31 has a groove on the right side for the outer support rod 22 to fit, and a baffle end is provided on the side of the hollow frame plate 31.

[0025] A fixed plate 32 is bolted to the side of the hollow frame plate 31, and a movable shaft 33 is rotatably installed on the inner side of the top of the fixed plate 32 through a through hole. A support spring 35 is welded to the end of the movable shaft 33, and the end of the support spring 35 is fixed to the inner end face of the side support plate 34. The side support plate 34 is fixed to the surface of the fixed plate 32. The side support plate 34 has an L-shaped cross-section, and cleaning brushes 36 are arranged at the bottom of the movable shaft 33.

[0026] The top of the sweeping brush 36 is set as a straight plate end, and the bottom of the sweeping brush 36 is set as a brush end. The bottom edge of the brush end of the sweeping brush 36 has an overall curved structure design.

[0027] The top of the support plate 57 has a placement groove, and the inner side of the placement groove is set with an independent inclined angle. The bottom of the inner wall of the placement groove of the support plate 57 has an arc structure design. The bottom of the support plate 57 is made of rigid PVC material, and the top of the support plate 57 is made of hard rubber material. The movement trajectory of the support plate 57 is approximately an elliptical trajectory, so as to realize slight vibration of the parts during the picking, lifting and transfer process.

[0028] The unloading platform 4 is fixed to the right side of the processing table 1 by bolts. A groove is provided at the center of the left side of the unloading platform 4 for the support platform 57 to move. A gap groove for matching the outer support rod 22 is provided at the position of the left side of the unloading platform 4 near the support platform 57. The top surface of the unloading platform 4 is designed with a slope from left to right, with the left side higher than the right side.

[0029] The air nozzle component 6 includes two limiting side plates 61 fixed to the outer surfaces of two side upright plates 21. Supports 62 are bolted to the top left and right sides of the limiting side plates 61, and an air nozzle pipe 63 is rotatably installed inside the support 62 through a through hole. Connecting pipes 64 are connected to both ends of the air nozzle pipe 63, and an air pump is installed at the end of the connecting pipe 64. A locking screw 65 is screwed into the top of the support 62 through a threaded hole. Several sets of air nozzles are equidistantly arranged on the inner end of the air nozzle pipe 63. The middle nozzle of each set of air nozzles is designed to be tilted in opposite directions, with the nozzles tilted towards the adjacent support plate 57. The tilt angle of the air nozzles is set to 15°–45°, and the nozzle diameter is 0.5–2mm. Specifically, the air pump can be an air compressor, providing a pressure of 0.5... Compressed air within the range of -0.8MPa is supplied through a connecting pipe 64, which is connected at both ends to the air pump outlet and the air inlet of the air nozzle 63 via quick-connect fittings. The air nozzle 63 is a stainless steel pipe, which is rotatably mounted on a support 62 via bearings. The support 62 is fixed to the limiting side plate 61 by bolts. Several sets of air nozzles are evenly spaced on the pipe wall of the air nozzle 63. Each set of air nozzles includes two symmetrically inclined nozzles with a nozzle orifice diameter of 0.5mm. The spray direction is at a 30-degree angle to the vertical direction, and the airflow from the two nozzles converges 50mm above the support plate 57 to ensure coverage of the part surface. The angle of the air nozzle 63 can be manually adjusted by loosening the locking screw 65 to align the nozzle with the part. After adjustment, tightening the locking screw 65 will fix the nozzle.

[0030] The pulley group 54, as a transmission mechanism, plays the role of deceleration, torque increase and power transmission. By selecting a suitable ratio of the diameter of the driving pulley to the driven pulley, the high speed of the variable frequency motor 55 can be converted into a lower speed and a larger torque required to drive the support shaft 53 and match the feeding rhythm, ensuring sufficient power to smoothly drive the support plate 57 carrying the parts. On the left and right sides of the side plate 21, at its lower or middle position, there are two outer support rods 22 that are rigidly connected symmetrically by welding or high-strength bolts. These two outer support rods 22 extend outward horizontally or slightly downward, and their ends are connected to the top of the processing table 1 below through the spring bolt group A23. Specifically, the bolt shank of the spring bolt group A23 is fixed on the processing table 1. The bolt shank passes through the pre-compressed spring and the connecting hole at the end of the outer support rod 22 in sequence, and is finally locked with a nut, thereby "suspending" or "elastically supporting" the outer support rod 22 on the table, allowing it to perform limited elastic displacement and swing in a plane perpendicular to the bolt axis. The spring bolt group A23 and the spring bolt group B24 have the same structure.

[0031] The guide frame assembly 3 is the inlet module for receiving and pre-processing parts. Its main body is a hollow frame plate 31, which is horizontally fixed to the upper left side of the side upright plate 21 by welding or bolting. The plate surface is designed with regularly arranged mesh or strip-shaped gaps. On the right edge of the hollow frame plate 31, one or more positioning grooves that are adapted to the outer contour of the outer support rod 22 of the suspension assembly 2 are precisely machined. The depth and width of the grooves are matched to ensure that the outer support rod 22 can be nested in them, realizing lateral positioning and constraint between the two and preventing relative displacement. In addition, on the side edge of the hollow frame plate 31, an integrally formed or additionally installed vertical baffle end is provided. The baffle end is set along part of the path of the expected rolling direction of the part, forming a guide and protective boundary.

[0032] The top of the cleaning brush 36 is a rigid straight plate, which is reliably connected to the bottom of the movable shaft 33 by bolt fastening to form a force transmission base. The bottom of the brush is integrated with a brush end, which is made of densely arranged wear-resistant fibers such as nylon, pig bristles or metal wire. The bottom edge of the brush end of the cleaning brush 36 is processed or shaped into a smooth curved structure. The radius of curvature of this curve is optimized so that it can smoothly support cylindrical parts of different diameters. The edge of the curve is the first contact point. Its smooth surface can convert the impact force of the part into rolling friction, which greatly reduces the risk of parts getting stuck or bouncing. When the part passes over it, the curve guides the brush to bend and deform in accordance with the cylindrical shape of the part, ensuring that the bristles can fully adhere to the surface of the part with a certain wrap angle and pressure, achieving adaptive cleaning and having a good effect on parts of different diameters.

[0033] At the top of the support plate 57, a placement groove adapted to the shape of the columnar part is formed along its length. The inner side of the placement groove is not vertical, but is set with an independent inclined angle. That is, the two sides of the groove wall can be designed with the same or different inclination angles, forming a wedge-shaped or V-shaped receiving space that is wider at the top and narrower at the bottom and has a guiding function. The bottom end of the inner wall of the placement groove is processed into a smooth and continuous arc structure. The radius of curvature of the arc matches the diameter of the target part, ensuring that the bottom surface of the part and the bottom of the groove are in line contact or surface contact, avoiding stress concentration or jamming caused by point contact. In terms of materials, the support plate 57 adopts a composite structure design: its bottom base is set as rigid Made of PVC, it provides sufficient structural strength, rigidity, and wear resistance to ensure no deformation during cyclic movement. The working surface at its top, which contacts the parts, is made of hard rubber. This hard rubber layer is firmly bonded to the PVC matrix through adhesive or in-mold molding processes, forming a functional surface that is both strong and flexible. Its funnel-shaped design, which is wider at the top and narrower at the bottom, allows cylindrical parts that are rolled in or placed from above to be automatically guided to the center of the placement slot, achieving a self-centering function. This effectively compensates for positional deviations during the loading process, ensuring that the parts are accurately and repeatedly positioned in the same transport posture each time, providing a benchmark for subsequent cleaning and unloading operations.

[0034] On the left side of the unloading platform 4, near the movable area of ​​the support platform 57, a clearance groove adapted to the shape of the outer support rod 22 is provided. This groove allows the suspension assembly 2 and its outer support rod 22 to have the necessary movement space during elastic vibration, preventing rigid collisions. The top bearing surface of the unloading platform 4 is specially designed, and its overall outline presents a continuous, left-high-right-low inclined surface from left to right. The inclination angle of this inclined surface is optimized to ensure that the parts can be automatically and orderly slid by gravity, while the sliding speed can be controlled to avoid damage to the parts due to collisions.

[0035] Both ends of the air nozzle 63 are connected to a connecting pipe 64 via threads or quick-connect fittings. The end of the connecting pipe 64 is connected to an external air pump, forming a compressed air supply passage. To fix the air nozzle 63 after angle adjustment, a threaded hole is machined at the top of the support 62, and a locking screw 65 is screwed in. When the air nozzle 63 is adjusted to the optimal spray angle, the locking screw 65 is tightened, and its end can press against the surface of the air nozzle 63 to prevent it from rotating during use. Several sets of air nozzles are equidistantly opened and fixed on the inner wall of the air nozzle 63. The middle nozzle in each set of air nozzles adopts an opposing tilt design, that is, the axes of the left and right nozzles are not parallel and they face inward and downward respectively. Their tilt angle is calculated and set to ensure that the high-speed airflow accurately converges and covers the surface area of ​​the parts on the adjacent support plate 57. This allows the device to flexibly adapt to columnar parts of different diameters or placement positions, optimize the airflow impact angle, and improve cleaning efficiency. The air nozzle 63 is connected to an external air pump via a connecting pipe 64, serving as a high-pressure air delivery pipeline and distribution center. Its internal channels guide the airflow evenly to each set of air nozzles. The "opposite tilt design" allows two airflows from adjacent nozzles to converge in a specific area, forming stronger turbulence and cleaning force. This effectively removes fine debris and oil stains adhering to the grooves, threads, and other complex structures on the surface of the parts. The cleaning effect far exceeds that of a single direct-blowing method. The tilt direction of the air nozzles is precisely set to face the adjacent support plate 57. When the support plate 57 carries the parts and moves to the apex near the air nozzle 63, the air nozzle 6 is activated. The high-speed airflow acts on the surface of the parts. This precise coordination in space and time enables automatic cleaning at fixed points and times during continuous feeding. The cleaning process is seamlessly integrated into the feeding process without additional interruptions, ensuring production efficiency.

[0036] Working principle: During the blanking process after machining cylindrical automotive parts, according to the attached... Figure 2 With appendix Figure 7 As shown, after the cylindrical automotive parts are processed, they are transported to the surface of the hollow frame plate 31 via a conveyor belt. The cylindrical automotive parts roll on the surface of the hollow frame plate 31. The cylindrical automotive parts first collide with and press against the cleaning brush 36. The cleaning brush 36 can be driven by force to rotate the movable shaft 33. The movable shaft 33 can pull the support spring 35. The cleaning brush 36 guides and straightens the cylindrical automotive parts so that they can fall stably and orderly. The brush end at the bottom of the cleaning brush 36 can clean the cylindrical automotive parts to a certain extent. Secondly, when the columnar automotive part rolls to the right side of the hollow frame plate 31, according to the attached... Figure 5 With appendix Figure 6As shown, when the variable frequency motor 55 is started by the external control panel of the equipment, the shaft end of the variable frequency motor 55 can drive the support shaft 53 to rotate through the pulley group 54. The support shaft 53 drives the movable support plate 56 to rotate. The movable support plate 56 drives the support platform 57 to rotate and swing through the through shaft 59. During the movement of the support platform 57, the top placement slot of its top is always steadily facing upward. When the horizontal plane of the top of the support platform 57 is lower than the horizontal plane of the top support block end of the side upright plate 21, the columnar automotive parts can be placed on the support block end surface of the side upright plate 21. After the support platform 57 rotates and moves for a new round, it can simultaneously transport the columnar parts on the support block end surface of the side upright plate 21. When the support platform 57 moves, it can generate a sway, driving the side upright plate 21 to swing slightly. During the swing, the side upright plate 21 is subjected to the spring bolt group A23 and The spring elasticity of the spring bolt group B24 causes the cylindrical automotive parts on the surface of the support plate 57 to vibrate. At the same time, when the support plate 57 lifts the cylindrical automotive parts to the top, the cylindrical automotive parts approach the air nozzle end of the air nozzle 63. Under the action of the external air pump, the high-speed airflow generated by the air pump enters the air nozzle 63 through the connecting pipe 64. The high-speed airflow blows and cleans the surface of the cylindrical automotive parts through the air nozzle end of the air nozzle 63. As the support plate 57 lifts and pushes the cylindrical automotive parts, the cylindrical automotive parts can be orderly placed onto the surface of the unloading plate 4. The surface of the unloading plate 4 is higher on the left and lower on the right, which can guide the cylindrical automotive parts, so that the initially cleaned cylindrical automotive parts can roll back onto the surface of the external conveyor belt, thereby facilitating the subsequent processing of the cylindrical automotive parts.
