Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts processing, and in particular to an automatic and precise feeding device for processing shaft products of new energy automobile parts. Background Art

[0002] The processing of new energy vehicle parts, especially shafts, requires extremely high precision, efficiency, and consistency. With the rapid development of the new energy vehicle industry, traditional loading devices have gradually exposed many shortcomings: First, existing storage mechanisms are mostly arranged horizontally or at low angles, relying on vibrating plates or manual assistance for arrangement. This can easily lead to problems such as material jamming and uneven feeding due to workpiece stacking, resulting in unstable processing time. Second, the weight screening of shafts before forging usually relies on offline testing. The sorting process is cumbersome and prone to human error, making it difficult to achieve real-time rejection of defective products, resulting in material waste and potential problems in subsequent processing. In addition, when traditional loading devices transfer shafts to the forging station, positioning deviations often lead to insufficient coaxiality, causing mold wear and even product scrapping, seriously affecting processing quality and equipment life. Although some automated equipment attempts to improve efficiency through robots or conveyor belts, the coordination between the sorting module and the processing unit is insufficient, and the control system lacks a closed-loop feedback mechanism for multi-sensor fusion, making it difficult to achieve a balance between efficiency and precision.

Combined with the guide sorting mechanism of the diversion arm, it can quickly eliminate overweight or underweight unqualified products, significantly improving sorting accuracy and efficiency, and reducing manual sorting costs.

[0013] 2. The axial alignment design of the receiving block and the feed push plate 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 preventing forging errors or mold damage caused by misalignment, thereby improving product processing precision and consistency. Furthermore, the controller dynamically coordinates the operation timing of each cylinder and motor through real-time feedback from multiple sensor signals (touch switches, photoelectric sensors, and pressure sensors), forming a stable closed-loop control logic. This ensures smooth operation and high fault tolerance, significantly reducing the risk of failures caused by mechanical interference or signal delays.

[0014] 3. In this invention, unqualified shafts are automatically recovered through the guide grooves and collection trays of the diverter arm, avoiding the safety hazards of manual sorting and reducing material waste. The entire device replaces traditional manual operations with fully automated processes, not only reducing labor costs but also reducing scrap rates and improving material utilization through precise weight detection and sorting.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 8 : The present invention proposes an automatic and precise feeding device for shaft products for processing new energy vehicle parts, comprising: a base 1; a storage rack 2 is provided on the base 1, and the storage rack 2 is used to store orderly arranged shafts 10; a controller 3 is mounted on the side wall of the support column of the storage rack 2, and a diverter rack 5 is provided on the base 1 on one side of the storage rack 2; a receiving cylinder 6 is provided horizontally in the diverter rack 5, and the end of the piston rod of the receiving cylinder 6 is fixedly connected to the receiving block 601; a feeding rack is provided on one side of the diverter rack 5 close to one end of the storage rack 2 8, and a forging table 9 is fixed on the other side of the end, and a feeding cylinder 801 is provided on the feeding rack 8, which is used to push the shaft 10 on the receiving block 601 horizontally into the forging table 9; a control rack 4 is provided on the end of the storage rack 2 close to the diversion rack 5, and the control rack 4 is used to control a single shaft 10 to enter and move to 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, which is used to cooperate with the receiving block 601 to remove the shaft 10 that does not meet the weight.

[0021] Among them, the upper end of the storage rack 2 is inclined at least fifteen degrees below the side where the control rack 4 is located, and a storage tray 201 is provided. The end of the storage tray 201 close to the control rack 4 is covered with a cover guide plate 202, and only a single shaft 10 is allowed to pass horizontally in the storage tray 201 below the cover guide plate 202; an arc-shaped recessed groove 2011 is provided on the side wall of the end of the storage tray 201 opposite to the control rack 4, which runs through it from left to right.

[0022] Among them, the extrusion wheel 203 is rotatably installed on the side wall of the storage tray 201 on the side away from the control and release rack 4, and a ring groove is provided on the wheel wall of the extrusion wheel 203; a touch switch 204 is provided on the side wall of the support column of the storage rack 2 opposite to the material receiving block 601. When the material receiving block 601 moves to the bottom of the control and release rack 4 to receive the material, the touch switch 204 is squeezed.

[0023] Among them, the left and right ends of the control and release frame 4 are respectively provided with hanging rods 401 distributed along the inclined direction of the storage tray 201, and the hanging rod 401 is slidably installed on the storage tray 201 through the ear plate, and a retaining ring is provided at the end of the hanging rod 401. A spring 402 is set on the hanging rod 401 between the retaining ring and the ear plate, and a control and release cylinder 403 is rotatably installed in the control and release frame 4. The control and release cylinder 403 is provided with a semicircular clamping opening 4031, and the shaft 10 enters and exits the control and release cylinder 403 from the clamping opening 4031. One end of the control and release frame 4 is provided with a control and discharge motor 404 for driving the control and release cylinder 403 to rotate; cams 405 are also fixed on the rotating shafts at both ends of the control and release cylinder 403, and the cam 405 always abuts against the annular groove of the extrusion wheel 203 on the corresponding side, and two interval angles are provided on the outer side wall of the cam 405 near the ring edge. The angle of the alignment sheet 4051 is 105 degrees, and the control and release frame 4 above the cam 405 is provided with a downward alignment frame 406, and the lower end of the alignment frame 406 is provided with a photoelectric sensor matching the alignment sheet 4051. When the card release port 4031 is facing, the tip of the cam 405 contacts the extrusion wheel 203, and the control and release frame 4 is in a state away from the storage tray 201. The shaft 10 in the control and release cylinder 403 naturally falls onto the material receiving block 601 under the action of gravity. When the card release port 4031 is facing the storage tray 201, the blunt end of the cam 405 contacts the cam 405, and the control and release frame 4 is in a state close to the storage tray 201. The two ends of the control and release cylinder 403 are stuck in the recessed groove 2011, and the shaft 10 in the storage tray 201 enters the control and release cylinder 403 from the card release port 4031.

[0024] Among them, a collecting tray 501 is provided below the end of the diverter rack 5 at the upper end of the material receiving cylinder 6, which is inclined away from the material receiving block 601. The lower end of the collecting tray 501 is an upward curved arc-shaped stop end 502, and the unqualified shaft parts 10 on the material receiving block 601 enter the collecting tray 501 for collection.

[0025] Among them, the upper end of the receiving block 601 is a V-groove that runs horizontally through, and pressure sensing sheets 602 are respectively provided in the inclined walls at both ends of the V-groove. When the shaft 10 is clamped in the V-groove of the receiving block 601, the pressure sensing sheet 602 is squeezed, and a pressure signal is generated and sent to the controller 3. The controller 3 judges whether the weight of the shaft 10 is qualified according to the numerical value of the pressure signal. The piston rod of the receiving cylinder 6 moves horizontally to drive the receiving block 601 to move horizontally, and receives the shaft 10 from the bottom of the control tube 403 to between the feed rack 8 and the forging table 9.

[0026] Among them, a diversion cylinder 701 is vertically provided on the diversion control frame 7, and a horizontal diversion arm 702 is fixedly provided at the end of the piston rod of the diversion cylinder 701. There are two diversion arms 702, which are parallel to each other and are respectively located on the left and right sides of the material receiving block 601. The inner side walls of the two material receiving blocks 601 are respectively inclined downward to one side of the diversion frame 5 with guide grooves 7021, and the part of the guide groove 7021 close to the diversion frame 5 is provided with a snap-in groove 7022 obliquely cut inwardly and downwardly. When the shaft 10 on the material receiving block 601 is an unqualified material, when the piston rod of the diversion cylinder 701 moves upward, the diversion arm 702 moves upward to lift the shaft 10 on the material receiving block 601, and the two ends of the shaft 10 are respectively 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.

[0027] Example 2. On the basis of Example 1, a push plate 802 is fixedly provided at the end of the piston rod of the feed cylinder 801. The axis of the push 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 judged to be qualified, the piston rod of the feed cylinder 801 is pushed out, and the push plate 802 pushes the shaft 10 on the receiving block 601 into the forging table 9 for forging operation.

[0028] The following further explains and illustrates each structure in the above content to help those skilled in the art better understand the present technical solution: The storage tray 201 of the accumulator 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 the action of gravity. The cover guide plate 202 limits the height of the opening at the end of the storage tray 201, allowing only a single shaft 10 to pass horizontally, thus preventing material jams caused by stacking multiple workpieces. The control rack 4 utilizes a resilient sliding design using a hanging rod 401 and a spring 402, allowing the control cylinder 403 to flexibly move along the tilt of the storage tray 201. When the controlled discharge motor 404 drives the control release cylinder 403 to rotate until the release opening 4031 faces the storage tray 201, the blunt end of the cam 405 contacts the extrusion wheel 203, and the two ends of the control release cylinder 403 engage the recessed groove 2011, causing the shaft 10 to slide from the storage tray 201 into the release opening 4031. When the release opening 4031 turns downward, the tip of the cam 405 contacts the extrusion wheel 203, and the control release cylinder 403 moves away from the storage tray 201. Under the action of gravity, the shaft 10 precisely falls into the V-groove of the receiving block 601. This process is achieved by detecting the angle signal of the alignment sheet 4051 on the cam 405 by a photoelectric sensor, ensuring the timing accuracy of the control release action and achieving the controlled release of a single piece.

[0029] Pressure sensing sheets 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 squeezes the pressure sensing sheets 602 on both sides, and 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, and guide the unqualified shaft 10 to the collection tray 501 through the guide groove 7021 and the inclined guide surface of the card slot 7022. The arc-shaped structure of the stop end 502 can prevent 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 pushed horizontally by the receiving cylinder 6 to the workstation between the forging table 9 and the feed rack 8 to ensure that only qualified products enter the subsequent processing flow.

[0030] When the receiving block 601, carrying the qualified shaft 10, moves to the forging station, the axis of the push plate 802 of the feed cylinder 801 is aligned with the shaft 10, and the piston rod pushes the shaft 10 precisely into the forging table 9 for processing. The V-groove position matching design of 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 the transfer process, avoiding forging errors caused by misalignment. In addition, the touch switch 204 is triggered when the receiving block 601 moves below the control and release frame 4, feeding back a signal indicating that the receiving block is in place to the controller 3, further coordinating the release rhythm of the control and release cylinder 403 to form a closed-loop control.

[0031] Through the tilting of the material storage rack 2, the mechanical and optoelectronic coordinated positioning of the control and release rack 4, the online weight detection of the receiving block 601, and the dynamic sorting of the diversion control rack 7, the entire system automates the entire process of shaft 10, from storage to sorting to forging. The operation of each cylinder (receiving cylinder 6, diversion cylinder 701, feed cylinder 801) and motor (discharge control motor 404) is centrally controlled by the controller 3. Combined with multi-signal feedback from pressure sensors, optoelectronic sensors, and touch switches 204, this ensures precise timing and stable operation, significantly improving processing efficiency and reducing the need for manual intervention.

[0032] Working principle: After the device is started, the storage tray 201 of the storage rack 2 is tilted at least 15 degrees, so that the shaft 10 automatically slides toward the control rack 4 under the action of gravity. The cover guide plate 202 at the end of the storage tray 201 limits the opening height, allowing only a single shaft 10 to pass horizontally to avoid accumulation and jamming of materials. When the receiving block 601 is driven by the receiving cylinder 6 to move to the bottom of the control rack 4, the touch switch 204 is triggered and the feedback signal is sent to the controller 3. The controller 3 then starts the control discharge motor 404 to drive the control cylinder 403 to rotate. During the rotation process, the release port 4031 of the control cylinder 403 switches the contact state between the cam 405 and the extrusion wheel 203 to realize the reciprocating movement of the control rack 4.

[0033] When the release control cylinder 403 rotates until the release opening 4031 faces the storage tray 201, the blunt end of the cam 405 contacts the extrusion wheel 203, and the two ends of the release control cylinder 403 engage the recessed groove 2011 of the storage tray 201. The shaft 10 in the storage tray 201 now slides into the release opening 4031. Subsequently, the release control motor 404 drives the release control cylinder 403 to rotate 105 degrees, causing the release opening 4031 to turn downward. The tip of the cam 405 contacts the extrusion wheel 203, and the release control cylinder 403 as a whole moves away from the storage tray 201. The shaft 10 freely falls from the release opening 4031 and precisely lands in the V-groove of the receiving block 601. During this process, the photoelectric sensor detects the 105-degree interval signal from the alignment sheet 4051 on the cam 405, ensuring the precise timing of the release control action and achieving a single-shot release of a single piece.

[0034] After the shaft 10 falls into the V-groove of the receiving block 601, its gravity squeezes the pressure sensing sheets 602 on both sides of the V-groove, and the pressure signal is transmitted to the controller 3, which determines whether the shaft 10 is qualified based on the 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 snap-in groove 7022 on the inner side of the diversion cylinder 701 lift the two ends of the shaft 10 and guide them to the inclined collection tray 501. The arc-shaped stop end 502 prevents the shaft 10 from sliding out, completing the automatic sorting of unqualified products. If the shaft 10 is qualified, the receiving cylinder 6 moves the receiving block 601 horizontally and transports the shaft 10 to the work station between the forging table 9 and the feed rack 8.

[0035] When the receiving block 601 is in place, the push plate 802 of the feeding cylinder 801 is pushed out under the instruction of the controller 3. The axis of the push plate 802 is coaxially aligned with the shaft 10, and the shaft 10 is smoothly pushed into the forging table 9 for processing. The V-groove position matching design of the push plate 802 and the receiving block 601, combined with the stroke control of the receiving cylinder 6, ensures the coaxiality of the transfer of the shaft 10 and avoids forging deviation. In the whole process, the controller 3 coordinates 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 push plate 802 through the multi-signal feedback of the touch switch 204, the photoelectric sensor and the pressure sensing sheet 602, forming a closed-loop control, realizing fully automated and precise operations from material storage, sorting to forging, significantly improving production efficiency and product consistency, while reducing manual intervention and scrap rate.
