Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an automatic and precise feeding device for shaft products in the processing of new energy vehicle parts. Background Technology

[0002] The processing of new energy vehicle components, especially shaft products, demands extremely high precision, efficiency, and consistency. With the rapid development of the new energy vehicle industry, traditional feeding devices have gradually revealed numerous shortcomings: First, existing storage mechanisms often employ horizontal or low-angle placement, relying on vibratory feeders or manual assistance for arrangement. This easily leads to problems such as jamming and uneven material supply due to workpiece stacking, resulting in unstable processing cycles. Second, the weight screening of shafts before forging typically relies on offline detection. The sorting process is cumbersome and prone to human error, making it difficult to remove defective products in real time, resulting in material waste and potential problems in subsequent processing. Furthermore, when traditional feeding devices transfer shafts to the forging station, positioning deviations often lead to insufficient coaxiality, causing mold wear and even product scrap, severely impacting processing quality and equipment lifespan. Although some automated equipment attempts to improve efficiency through robotic arms or conveyor belts, the coordination between their sorting modules and processing units is insufficient, and the control system lacks a closed-loop feedback mechanism based on multi-sensor fusion, making it difficult to balance high efficiency and precision. Summary of the Invention

[0003] This invention relates to an automatic and precise feeding device for shaft products in the processing of new energy vehicle parts. It is an integrated device that combines material storage, precise sorting, automatic feeding and closed-loop control to solve the core problems of low efficiency, high scrap rate and strong dependence on manual labor in the prior art, and to meet the urgent needs of high-precision and mass production of new energy vehicle parts.

[0004] This invention provides an automatic and precise feeding device for shaft products in the processing of new energy vehicle parts, specifically comprising: a base; a storage rack on the base for storing orderly arranged shafts; a controller mounted on the side wall of the support column of the storage rack, and a diverter rack on one side of the base; a receiving cylinder horizontally positioned in the diverter rack, with a receiving block fixedly connected to the piston rod end of the receiving cylinder; a feeding rack on one side of the diverter rack near the storage rack, and a forging table fixedly positioned on the other side of the same end, with a feeding cylinder on the feeding rack for horizontally pushing the shafts on the receiving block into the forging table; a control release rack on one end of the storage rack near the diverter rack for controlling individual shafts to move into the receiving block below; and a diverter control rack vertically fixed on the base between the storage rack and the diverter rack for cooperating with the receiving block to remove shafts that do not meet the weight requirements.

[0005] Optionally, the upper end of the storage rack is inclined at least 15 degrees downward towards the side where the control frame is located, and a storage tray is provided. The end of the storage tray near the control frame is covered with a cover plate. Only a single shaft is allowed to pass laterally in the storage tray below the cover plate. An arc-shaped recessed groove that runs through the left and right sides is provided on the side wall of the storage tray opposite to the control frame.

[0006] Optionally, a pressing wheel is rotatably installed on the side wall of the storage tray away from the control rack, and the wheel wall of the pressing wheel is provided with an annular groove; a touch switch is provided on the side wall of the support column of the storage rack opposite to the receiving block, and the touch switch is squeezed when the receiving block moves to receive material under the control rack.

[0007] Optionally, the left and right ends of the control release frame are respectively provided with hanging rods distributed along the inclined direction of the storage tray. The hanging rods are slidably installed on the storage tray through ear plates. The end of the hanging rod is provided with a retaining ring. A spring is fitted on the hanging rod between the retaining ring and the ear plate. A control release cylinder is rotatably installed in the control release frame. The control release cylinder has a semi-circular locking opening. The shaft enters and exits the control release cylinder through the locking opening. One end of the control release frame is provided with a control release motor for driving the rotation of the control release cylinder. Cams are also fixed on the rotating shafts at both ends of the control release cylinder. The cams always abut against the annular groove of the extrusion wheel on the corresponding side. The outer sidewall of the cam is close to the annular edge. Two alignment plates with an angle of degrees are provided at the position. A downward alignment frame is provided on the control release frame above the cam. The lower end of the alignment frame is provided with a photoelectric sensor that matches the alignment plates. When the release port is facing, the tip of the cam contacts the extrusion wheel, and the control release frame is in a state away from the storage tray. The shaft in the control release cylinder falls naturally onto the receiving block under the action of gravity. When the release port is facing the storage tray, the blunt end of the cam contacts the cam, and the control release frame is in a state close to the storage tray. The two ends of the control release cylinder are engaged in the recessed receiving groove, and the shaft in the storage tray enters the control release cylinder from the release port.

[0008] Optionally, a collection tray is provided below the diverter at the upper end of the receiving cylinder, tilted away from the receiving block. The lower end of the collection tray is an upward-curved arc-shaped stop end, and defective shafts on the receiving block enter the collection tray for collection.

[0009] Optionally, the upper end of the receiving block is a transversely penetrating V-groove, and pressure sensing plates are respectively provided in the inclined walls at both ends of the V-groove. When the shaft is placed in the V-groove of the receiving block, the pressure sensing plates are squeezed, generating a pressure signal that is sent to the controller. The controller determines whether the weight of the shaft is qualified based on the magnitude of the pressure signal. The piston rod of the receiving cylinder moves horizontally, causing the receiving block to move horizontally, receiving the shaft from below the control cylinder to between the feeding rack and the forging table.

[0010] Optionally, the diversion control frame is vertically equipped with a diversion cylinder. The piston rod of the diversion cylinder is fixed with a horizontal diversion arm. There are two diversion arms, which are parallel to each other and located on the left and right sides of the receiving block respectively. The inner sidewalls of the two receiving blocks are respectively provided with guide grooves that are inclined downwards to one side of the diversion frame. The part of the guide groove near the diversion frame is provided with a snap-in groove that is obliquely cut inwards and downwards. When the shaft on the receiving block is a defective part, when the piston rod of the diversion cylinder moves upwards, the diversion arm moves upwards and lifts the shaft on the receiving block. The two ends of the shaft are guided from the snap-in groove and fall into the guide groove, and then roll into the collection tray under the guidance of the guide groove.

[0011] Optionally, a pusher plate is fixedly provided at the end of the piston rod of the feeding cylinder. The axis of the pusher plate is consistent with the axis of the shaft on the receiving block. After the shaft on the receiving block is determined to be qualified, the piston rod of the feeding cylinder is pushed out, and the pusher plate pushes the shaft on the receiving block into the forging table for forging operation.

[0012] This invention provides an automatic and precise feeding device for shaft products in the processing of new energy vehicle parts, which has the following beneficial effects:

[0013] 1. This invention achieves full automation of shaft component processing from storage and individual release to sorting through the tilted design of the storage rack and the mechanical-photoelectric coordinated control of the release rack. The storage tray utilizes gravity self-sliding and the height-limiting structure of the cover plate to ensure that shaft components are arranged in an orderly manner and released one by one, solving the problem of material jamming caused by stacking in traditional feeding. The rotation of the release cylinder, combined with the precise positioning of the cam and photoelectric sensor, ensures the controllable release of one component at a time, avoiding over- or under-weighting. The V-groove of the receiving block integrates pressure sensing technology, which can detect the weight of the shaft components in real time. Combined with the guiding and sorting mechanism of the diverter arm, it can quickly remove overweight or underweight defective products, significantly improving sorting accuracy and efficiency and reducing manual sorting costs.

[0014] 2. The axial alignment design of the receiving block and the feeding pusher in this invention, combined with a closed-loop control system, ensures that qualified shaft parts maintain high coaxiality when transferred to the forging table, effectively avoiding forging errors or mold damage caused by misalignment, thereby improving product processing accuracy and consistency. Furthermore, the controller dynamically coordinates the timing of actions of each cylinder and motor through real-time feedback from multiple sensor signals (touch switches, photoelectric sensors, pressure sensors), forming a stable closed-loop control logic. This ensures smooth operation and high fault tolerance of the device, significantly reducing the risk of failures caused by mechanical interference or signal delays.

[0015] 3. In this invention, defective shaft parts are automatically recycled via the guide groove of the diversion arm and the collection tray, avoiding the safety hazards of manual sorting and reducing material waste. The entire device replaces traditional manual operation with full-process automation, not only reducing labor costs but also reducing scrap rates and improving material utilization through precise weight detection and sorting. Furthermore, the device's compact structure and modular design facilitate integration into existing production lines, meeting the high-precision, high-volume production needs of new energy vehicle parts and providing reliable technical support for intelligent manufacturing upgrades.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1 to 8 :

[0040] This invention proposes an automatic and precise feeding device for shaft products in the processing of new energy vehicle parts, comprising: a base 1; a storage rack 2 on the base 1 for storing orderly arranged shaft parts 10; a controller 3 mounted on the side wall of the support column of the storage rack 2; a diversion rack 5 on one side of the base 1 of the storage rack 2; a receiving cylinder 6 horizontally arranged in the diversion rack 5, with a receiving block 601 fixedly connected to the end of the piston rod of the receiving cylinder 6; and a feeding rack on one side of the diversion rack 5 near the storage rack 2. 8. On the other side of this end, a forging table 9 is fixedly provided. A feeding cylinder 801 is provided on the feeding rack 8 to push the shaft 10 on the receiving block 601 horizontally into the forging table 9. A control rack 4 is provided on the storage rack 2 near the diversion rack 5. The control rack 4 is used to control the entry of a single shaft 10 into the receiving block 601 below. A diversion control rack 7 is fixed vertically upward on the base 1 between the storage rack 2 and the diversion rack 5 to cooperate with the receiving block 601 to remove shafts 10 that do not meet the weight requirements.

[0041] Among them, the upper end of the storage rack 2 is inclined at least 15 degrees downward towards the side where the control rack 4 is located, and a storage tray 201 is provided. The end of the storage tray 201 near the control rack 4 is covered with a cover plate 202. Only a single shaft 10 is allowed to pass laterally in the storage tray 201 below the cover plate 202. An arc-shaped recessed groove 2011 that runs through the left and right is provided on the side wall of the end of the storage tray 201 opposite to the control rack 4.

[0042] Among them, the concave receiving groove 2011 is mounted on the side wall of the storage tray 201 away from the control frame 4, and the extrusion wheel 203 is provided with an annular groove on the wheel wall; the support column of the storage rack 2 is provided with a touch switch 204 on the side wall opposite to the receiving block 601. When the receiving block 601 moves to receive material below the control frame 4, the touch switch 204 is squeezed.

[0043] The control frame 4 has hanging rods 401 at its left and right ends, which are distributed along the inclined direction of the storage tray 201. The hanging rods 401 are slidably mounted on the storage tray 201 through ear plates. The end of the hanging rod 401 is provided with a retaining ring. A spring 402 is fitted on the hanging rod 401 between the retaining ring and the ear plate. The control playback cylinder 403 is rotatably mounted in the control frame 4. The control playback cylinder 403 has a semi-circular release port 4031. The shaft 10 enters and exits the control playback cylinder 403 through the release port 4031. One end of the control frame 4 is provided with a control discharge motor 404 for driving the control playback cylinder 403 to rotate. Cams 405 are also fixed on the rotating shafts at both ends of the control playback cylinder 403. The cams 405 always abut against the annular groove of the extrusion roller 203 on the corresponding side. Two spaced angles are provided on the outer side wall of the cam 405 near the annular edge. The alignment sheet 4051 has an alignment angle of 105 degrees. The control release frame 4 above the cam 405 is provided with a downward alignment frame 406. The lower end of the alignment frame 406 is provided with a photoelectric sensor that matches the alignment sheet 4051. When the release port 4031 is facing, the tip of the cam 405 is in contact with the extrusion wheel 203, and the control release frame 4 is in a state away from the storage tray 201. The shaft 10 in the control release cylinder 403 falls naturally onto the receiving block 601 under the action of gravity. When the release port 4031 is facing the storage tray 201, the blunt end of the cam 405 is in contact with the cam 405, and the control release frame 4 is in a state close to the storage tray 201. The two ends of the control release cylinder 403 are engaged in the recessed receiving groove 2011, and the shaft 10 in the storage tray 201 enters the control release cylinder 403 from the release port 4031.

[0044] Among them, the diverter 5 at the upper end of the receiving cylinder 6 is provided with a collection tray 501 at the lower end of the diverter 5 that is inclined away from the receiving block 601. The lower end of the collection tray 501 is an upwardly curved arc-shaped stop end 502. The defective shaft 10 on the receiving block 601 enters the collection tray 501 for collection.

[0045] The upper end of the receiving block 601 is a transversely penetrating V-groove. Pressure sensing plates 602 are respectively provided in the inclined walls at both ends of the V-groove. When the shaft 10 is placed in the V-groove of the receiving block 601, the pressure sensing plates 602 are squeezed and generate a pressure signal, which is sent to the controller 3. The controller 3 judges whether the weight of the shaft 10 is qualified according to the value of the pressure signal. The piston rod of the receiving cylinder 6 moves horizontally, which drives the receiving block 601 to move horizontally, receiving the shaft 10 from below the control cylinder 403 to between the feeding rack 8 and the forging table 9.

[0046] The diversion control frame 7 is vertically equipped with a diversion cylinder 701. The piston rod of the diversion cylinder 701 is fixed with a horizontal diversion arm 702. There are two diversion arms 702, which are parallel to each other and located on the left and right sides of the receiving block 601. The inner sidewalls of the two receiving blocks 601 are respectively provided with guide grooves 7021 that are inclined downwards towards one side of the diversion frame 5. The part of the guide groove 7021 near the diversion frame 5 is provided with a snap-in groove 7022 that is cut inwards and downwards. When the shaft 10 on the receiving block 601 is a defective material, when the piston rod of the diversion cylinder 701 moves upwards, the diversion arm 702 moves upwards and lifts the shaft 10 on the receiving block 601. The two ends of the shaft 10 are guided from the snap-in groove 7022 and fall into the guide groove 7021, and then roll into the collection tray 501 under the guidance of the guide groove 7021.

[0047] In Example 2, based on Example 1, a pusher plate 802 is fixedly provided at the end of the piston rod of the feed cylinder 801. The axis of the pusher plate 802 is consistent with the axis of the shaft 10 on the receiving block 601. After the shaft 10 on the receiving block 601 is determined to be qualified, the piston rod of the feed cylinder 801 is pushed out, and the pusher plate 802 pushes the shaft 10 on the receiving block 601 into the forging table 9 for forging operation.

[0048] The following provides further explanation and description of the various structures mentioned above to help those skilled in the art better understand this technical solution:

[0049] The storage tray 201 of the storage rack 2 is tilted at an angle of at least 15 degrees, allowing the shaft 10 to slide naturally toward the control rack 4 under gravity. The cover plate 202 restricts the height of the opening at the end of the storage tray 201, allowing only a single shaft 10 to pass laterally, thus avoiding jamming problems caused by stacking multiple workpieces. The control rack 4, through the elastic sliding design of the hanging rod 401 and the spring 402, allows the control cylinder 403 to move flexibly along the tilt direction of the storage tray 201. When the controlled discharge motor 404 drives the controlled discharge cylinder 403 to rotate until the release port 4031 faces the storage tray 201, the blunt end of the cam 405 contacts the extrusion wheel 203, and both ends of the controlled discharge cylinder 403 are embedded in the recessed receiving grooves 2011. The shaft 10 slides from the storage tray 201 into the release port 4031. When the release port 4031 turns downward, the tip of the cam 405 contacts the extrusion wheel 203, the controlled discharge cylinder 403 moves away from the storage tray 201, and the shaft 10 falls precisely into the V-groove of the receiving block 601 under the action of gravity. This process uses a photoelectric sensor to detect the angle signal of the alignment sheet 4051 on the cam 405 to ensure the timing accuracy of the controlled discharge action and achieve controllable release of a single piece at a time.

[0050] Pressure sensing plates 602 are embedded in the inclined walls at both ends of the V-groove of the receiving block 601. When the shaft 10 falls into the V-groove, its gravity compresses the pressure sensing plates 602 on both sides. The controller 3 calculates the weight of the shaft through the pressure signal. If the weight is unqualified, the controller 3 triggers the diversion cylinder 701 to drive the diversion arm 702 to rise and lift the shaft 10. The unqualified shaft 10 is guided to the collection tray 501 through the inclined guide surfaces of the guide groove 7021 and the locking groove 7022. The arc-shaped structure of the stop end 502 prevents the shaft 10 from rolling out of the tray, realizing automatic sorting. The qualified shaft 10 is retained on the receiving block 601 and is horizontally pushed by the receiving cylinder 6 to the station between the forging table 9 and the feeding rack 8, ensuring that only qualified products enter the subsequent processing.

[0051] When the receiving block 601, carrying the qualified shaft 10, moves to the forging station, the axis of the push plate 802 of the feeding cylinder 801 aligns with the shaft 10. The piston rod pushes the shaft 10 precisely into the forging table 9 for processing. The matching design of the V-groove position between the push plate 802 and the receiving block 601, combined with the stroke control of the receiving cylinder 6, ensures the coaxiality of the shaft 10 during transfer, avoiding forging errors caused by misalignment. Furthermore, the touch switch 204 is triggered when the receiving block 601 moves below the control release frame 4, sending a receiving positioning signal to the controller 3, further coordinating the rhythm of the control release cylinder 403 releasing the shaft 10, forming a closed-loop control.

[0052] Through the tilted storage of the storage rack 2, the mechanical-photoelectric collaborative positioning of the control rack 4, the online weight detection of the receiving block 601, and the dynamic sorting of the diversion control rack 7, the entire device realizes full automation of the shaft 10 from storage to sorting to forging. The actions of each cylinder (receiving cylinder 6, diversion cylinder 701, feeding cylinder 801) and motor (control discharge motor 404) are all centrally controlled by the controller 3. Combined with the multi-signal feedback of pressure sensing, photoelectric sensing and touch switch 204, the device ensures accurate timing of actions and stable operation, significantly improving processing efficiency and reducing the need for manual intervention.

[0053] Working principle:

[0054] After the device is started, the storage tray 201 of the storage rack 2, due to its design of being tilted at least 15 degrees, causes the shaft 10 to automatically slide towards the control release frame 4 under the action of gravity. The cover plate 202 at the end of the storage tray 201 restricts the opening height, allowing only a single shaft 10 to pass laterally, avoiding material accumulation and jamming. When the receiving block 601 is driven by the receiving cylinder 6 to move to below the control release frame 4, the touch switch 204 is triggered, and a feedback signal is sent to the controller 3. The controller 3 then starts the control release motor 404 to drive the control release cylinder 403 to rotate. During the rotation, the release port 4031 of the control release cylinder 403 achieves the reciprocating movement of the control release frame 4 by switching the contact state between the cam 405 and the extrusion wheel 203.

[0055] When the release cylinder 403 rotates to the position where the release port 4031 faces the storage tray 201, the blunt end of the cam 405 contacts the extrusion wheel 203, and both ends of the release cylinder 403 are embedded in the recessed grooves 2011 of the storage tray 201. At this time, the shaft 10 inside the storage tray 201 slides into the release port 4031. Subsequently, the release motor 404 continues to drive the release cylinder 403 to rotate 105 degrees, the release port 4031 turns downward, the tip of the cam 405 contacts the extrusion wheel 203, the release cylinder 403 moves away from the storage tray 201, and the shaft 10 falls freely from the release port 4031, accurately falling into the V-groove of the receiving block 601. During this process, the photoelectric sensor detects the 105-degree interval angle signal of the alignment sheet 4051 on the cam 405 to ensure the precise timing of the release action and achieve single-piece release.

[0056] After the shaft 10 falls into the V-groove of the receiving block 601, its gravity presses against the pressure sensing plates 602 on both sides of the V-groove. The pressure signal is transmitted to the controller 3, which determines whether the shaft 10 is qualified based on a preset weight threshold. If the shaft 10 is overweight or underweight, the controller 3 activates the diversion cylinder 701 of the diversion control frame 7, driving the diversion arm 702 to move upward. The guide groove 7021 and the locking groove 7022 on its inner side lift both ends of the shaft 10 and guide it into the inclined collection tray 501. The arc-shaped stop end 502 prevents the shaft 10 from slipping out, completing the automatic sorting of defective products. If the shaft 10 is qualified, the receiving cylinder 6 moves the receiving block 601 horizontally, conveying the shaft 10 to the station between the forging table 9 and the feeding frame 8.

[0057] Once the receiving block 601 is in place, the pusher 802 of the feeding cylinder 801 is pushed out under the command of the controller 3. The axis of the pusher 802 is coaxially aligned with the shaft 10, smoothly pushing the shaft 10 into the forging table 9 for processing. The V-groove position matching design of the pusher 802 and the receiving block 601, combined with the stroke control of the receiving cylinder 6, ensures the coaxiality of the shaft 10 transfer and avoids forging misalignment. In the entire process, the controller 3 coordinates the timing of the rotation of the control cylinder 403, the movement of the receiving block 601, the lifting and lowering of the diverter arm 702, and the pushing of the pusher 802 through multi-signal feedback from the touch switch 204, photoelectric sensor, and pressure sensing plate 602, forming a closed-loop control. This achieves fully automated and precise operation from material storage and sorting to forging, significantly improving production efficiency and product consistency, while reducing manual intervention and scrap rate.
