Description

Technical Field

[0001] This invention belongs to the technical field of steel pipe transfer equipment, specifically relating to a transfer device for steel pipe processing. Background Technology

[0002] Currently, in the manufacturing process of electric vehicles, the transfer of various steel pipe components (such as frame structure pipes, exhaust pipes, battery bracket pipes, etc.) generally relies on traditional manual handling, hoisting, or simple trolley transport methods. Although these methods are simple to operate, they have problems such as low efficiency and prominent safety hazards: for example, during manual handling, improper operation can easily cause scratches or deformation of the component surface; improper control during hoisting operations may cause the steel pipe to fall off, leading to safety accidents; and rolling transport is prone to slight deformation of the pipe due to collisions, affecting the accuracy of subsequent assembly.

[0003] Especially in the electric vehicle frame welding or battery pack bracket assembly sections, steel pipe fittings need to be transferred in an orderly manner from the storage area to the welding or assembly station. To avoid structural damage or assembly deviations caused by rolling or collision during the transfer process, intermittent conveying equipment is often used to transport the steel pipes in an orderly and isolated manner.

[0004] However, existing intermittent steel pipe conveying equipment can only transport steel pipes of a single size. When conveying long steel pipes, the center of gravity is prone to shift, which can cause the steel pipe to fall during the conveying process. When conveying steel pipes of different diameters, the receiving distance of the steel pipe is fixed, so it can only receive and transport steel pipes of a single diameter, which limits its applicability. In addition, when storing steel pipe fittings in multi-layer racks or high-bay warehouses, it still relies on hoisting equipment, which is not only inefficient but also poses safety risks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a transfer device for steel pipe processing.

[0006] The technical solution adopted to solve the above technical problems is: a transfer device for steel pipe processing, including a base plate, universal wheels installed at the bottom end of the base plate, a fixed frame welded and fixed at the rear top of the base plate, a fixed rod fixedly connected between the two sides of the fixed frame, a mode switching component rotatably connected to the fixed rod, an intermittent conveying component connected to the top of the mode switching component, a storage hopper fixedly connected to the upper side wall of the fixed frame, the storage hopper being located above the intermittent conveying component, and a material blocking component fixedly connected to the top of the base plate. The mode switching component and the material blocking component cooperate to realize the intermittent conveying component switching between feeding and conveying modes, and the material blocking component provides protection for the entire process of steel pipe conveying and storage.

[0007] The top of the front wall of the storage hopper is fixed with inclined and symmetrical guide plates. The guide plates are connected to the intermittent conveying component of the feeding mode to realize feeding. The bottom of the storage hopper is symmetrically provided with a rotating groove, and an adjustable intermittent discharge component is rotatably provided in the rotating groove on both sides.

[0008] Furthermore, the mode switching component includes a track limiting frame, a fixed base, and a hydraulic push rod. There are two track limiting frames arranged symmetrically on the left and right. The two sides of the fixed base are fixedly connected with a sliding limiting rod one and a sliding limiting rod two. The sliding limiting rod one is located in front of the sliding limiting rod two.

[0009] The bottom end of the hydraulic push rod is rotatably connected to the outer wall of the middle section of the fixed rod, and the movable top end of the hydraulic push rod is rotatably connected to the outer wall of the second sliding limit rod. The second sliding limit rod and the first sliding limit rod slide within the track limit frame to achieve the tilting, rising and resetting of the fixed seat.

[0010] Through the above technical solution, the hydraulic push rod, as a power source, can provide smooth and high-thrust linear motion, which is very suitable for attitude adjustment with heavy load. The sliding limit rod 2, the sliding limit rod 1, and the track limit frame form a statically indeterminate support structure, ensuring that the fixed seat and the intermittent conveying components on it do not twist or jam during the movement, and the movement trajectory has excellent rigidity.

[0011] Furthermore, the lower side wall of the track limiting frame is provided with a first propulsion limiting hole and a second propulsion limiting hole along the parallel line of the bottom plate. A rotating limiting hole is provided through the upper front end of the track limiting frame. The rotating limiting hole is opened with the front end of the second propulsion limiting hole as the rotation fulcrum and the distance between the first sliding limiting rod and the second sliding limiting rod as the radius. The front end of the track limiting frame is provided with a second rising limiting hole at an angle of 45°. The front end of the rotating limiting hole is provided with a first rising limiting hole at an angle of 45°. The first rising limiting hole and the second rising limiting hole have the same angle of inclination.

[0012] The second sliding limit rod is in sliding engagement with the first pushing limit hole, the first rotating limit hole, and the first rising limit hole, and the first sliding limit rod is in sliding engagement with the second pushing limit hole and the second rising limit hole.

[0013] Through the above technical solution, the track limit frame is set with a three-stage trajectory of propulsion, rotation and rising. The mechanical track hard limit guides and limits the simple linear motion of the hydraulic push rod, thereby realizing the design of the predetermined composite motion trajectory, enabling the equipment to switch between different functional modes accurately and stably, and with stronger anti-interference ability.

[0014] Furthermore, the material blocking assembly includes a first baffle plate arranged symmetrically on the left and right, a slide rail fixedly installed on the upper surface of the base plate, and a movable limiting shell. The slide rail and the movable limiting shell are arranged in parallel. There are two slide rails, which are respectively located on the front and rear sides of the movable limiting shell. The rear end of the first baffle plate is provided with a second baffle plate. The side wall of the second baffle plate is slidably connected to the inner side wall of the storage hopper.

[0015] The front and rear bottom ends of the first baffle plate are both fixedly connected to sliders, and the sliders are slidably connected to the adjacent slide rails. The middle bottom end of the first baffle plate is fixedly connected to a movable block. The inner walls of both sides of the movable limiting shell are rotatably connected to a bidirectional threaded screw. The outer wall of the bidirectional threaded screw is threadedly connected to the side wall of the movable block. The side wall of the movable limiting shell is fixedly installed with a motor, and the output end of the motor is fixedly connected to one end of the bidirectional threaded screw.

[0016] The sidewalls of the first baffle plate are provided with mounting holes that are adapted to the shape of the track limiting frame, and the two track limiting frames are respectively fixedly installed in the mounting holes on both sides.

[0017] Through the above technical solution, guard plate one and guard plate two form protection on both sides of the steel pipe conveying path, preventing the steel pipe from rolling off, ensuring that the conveying channel remains centered, and avoiding the steel pipe falling due to a shift in its center of gravity during conveying. Motor one drives a bidirectional threaded screw, causing the movable blocks on both sides to move synchronously towards or away from each other, thereby adjusting the distance between guard plate one and guard plate two to match steel pipes of different lengths. Simultaneously, two track limiting frames are fixedly installed in the mounting holes on both sides, integrating the structural load-bearing component of the mode switching assembly (which serves as the motion execution component) into the material-stopping assembly, simplifying the overall frame and enhancing structural compactness and overall rigidity.

[0018] Furthermore, the intermittent conveying assembly includes a U-shaped housing one and a U-shaped housing two. The bottom end of the U-shaped housing one is fixedly connected to the upper surface of the fixed base. The U-shaped housing two is located inside the U-shaped housing one. The U-shaped housing one and the U-shaped housing two are arranged parallel to each other. Right-angle serrated grooves are arranged at equal intervals on the top ends of the U-shaped housing one and the U-shaped housing two.

[0019] The front and rear ends of the left and right side walls of the second U-shaped housing are rotatably connected to movable rods, and the four movable rods are arranged in the same direction. A rotating rod is fixedly connected to the side of each movable rod near the inner side wall of the first U-shaped housing. The side wall of each rotating rod is rotatably connected through the side wall of the first U-shaped housing. A second motor is fixedly installed on the outer side wall of the first U-shaped housing, and the output end of the second motor is fixedly connected to one end of the rotating rod.

[0020] With the above technical solution, regardless of whether it is horizontal or inclined, the steel pipe can be supported and intermittently transported by the right-angle sawtooth groove at the top, preventing it from rolling randomly in inclined or horizontal states, and realizing controllable and discrete step conveying. This is more conducive to the separation and positioning of single steel pipes than continuous rolling conveying.

[0021] Furthermore, the adjustable intermittent discharge assembly includes a limiting plate rotatably mounted on the inner wall of the rotating groove and a servo electric cylinder fixedly mounted on the side wall of the storage hopper. The two limiting plates are symmetrically arranged. A connecting block is fixedly connected to the bottom of the movable end of the servo electric cylinder. A connecting rod is rotatably connected to both sides of the connecting block. A rotating disk is fixedly connected to the end of the limiting plate near the connecting rod through the side wall of the rotating groove. The other end of the connecting rod is rotatably connected to the outer wall of the eccentric part of the adjacent rotating disk.

[0022] The inner sidewalls of the limiting plate are all fixed with protective plates, and the bottom end of the limiting plate is provided with a rotating groove II. The bottom ends of the two rotating groove II are rotatably connected to an intermittent feeding mechanism, and the protective plate is located above the intermittent feeding mechanism.

[0023] The above technical solution allows for adjustment of the discharge port diameter according to steel pipes of different diameters. During adjustment, the servo electric cylinder provides precise position control and drives two rotating disks to rotate via a connecting rod, thereby causing two limiting plates to open and close synchronously like a "gate". This achieves stepless, electric adjustment of the discharge port width, enabling rapid adaptation to steel pipes of different diameters with high adjustment accuracy.

[0024] Furthermore, the intermittent feeding mechanism includes arc-shaped feeding plates symmetrically rotatably installed on the inner walls of the two rotating slots on both sides, and brackets 1 symmetrically fixed on the outer walls of the two limiting plates on both sides. The upper and lower ends of the arc-shaped feeding plates are provided with slots, and rolling rods are rotatably connected between the inner walls of the two sides of the slots. Brackets 2 are fixedly connected to the side walls of the arc-shaped feeding plates near the adjacent brackets 1. Servo electric cylinders 2 are rotatably connected between the adjacent brackets 1 and brackets 2.

[0025] By using the above technical solutions, the opening and closing of the bottom outlet of the storage hopper and the feeding rhythm are controlled, and the intermittent conveying components work together to achieve active and flexible single-piece feeding, which solves the problems of congestion, uneven feeding and impact that are easily caused by gravity feeding.

[0026] Furthermore, a control panel is installed on the side wall of the fixing frame, and the control panel is electrically connected to the hydraulic push rod, motor one, motor two, servo cylinder one, and servo cylinder two.

[0027] The above technical solution integrates the control of all actuators such as motors, electric cylinders, and hydraulic cylinders onto a single control surface, achieving simplified and convenient human-machine interaction.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) By setting up a mode switching component, intermittent conveying component, storage hopper and baffle component, the mode switching component and the baffle component limit the cooperation, and the switching between the discharge mode and the feeding mode can be realized. In the feeding mode, the steel pipe below can be transported to the storage hopper in an orderly manner through the inclined intermittent conveying component for temporary storage. There is no need to use external hoisting tools, which reduces the safety risk of manual handling. In the discharge mode, the horizontal intermittent conveying component and the storage hopper use the gravitational potential energy to discharge the material. It can controllable and discrete step conveying, which is more conducive to the separation and positioning of single steel pipes of different sizes.

[0030] (2) By setting up the baffle assembly, the baffle plate one and the baffle plate two form protection on both sides of the steel pipe conveying path, ensuring that the conveying channel is always in the center, avoiding the steel pipe from falling due to the shift of the center of gravity during conveying, and the protection spacing can be adjusted according to the length of the steel pipe, improving the overall applicability of the structure, while also taking into account the structural load-bearing components of the mode switching assembly, simplifying the overall frame, and enhancing the structural compactness and overall rigidity.

[0031] (3) By setting an adjustable intermittent discharge component, the discharge port width can be adjusted according to the steel pipes of different diameters, which is suitable for steel pipes of different sizes, and realizes the discharge of single steel pipes at a time and with low impact. This solves the problems of congestion, uneven material and impact that are easily caused by gravity discharge, and further improves the applicability of the equipment. Attached Figure Description

Detailed Implementation

[0043] 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.

[0044] like Figures 1-10As shown, a steel pipe processing transfer device in this embodiment includes a base plate 1. A caster wheel 2 is installed at the bottom of the base plate 1 to facilitate the overall movement of the device. A fixed frame 3 is welded and fixed to the rear side of the top of the base plate 1. A fixed rod 301 is fixed between the two sides of the fixed frame 3. A mode switching component 4 is rotatably connected to the fixed rod 301. An intermittent conveying component 6 is connected to the top of the mode switching component 4. A storage hopper 7 is fixed to the upper side wall of the fixed frame 3 to temporarily store a certain number of steel pipes and guide them into the conveying channel in an orderly manner. The storage hopper 7 is located above the intermittent conveying component 6. A baffle component 5 is also fixed to the top of the base plate 1. The mode switching component 4 and the baffle component 5 cooperate to realize the switching of the intermittent conveying component 6 between feeding and conveying modes. The baffle component 5 provides protection for the entire process of steel pipe conveying and storage.

[0045] The top of the front wall of the storage hopper 7 is fixed with an inclined and symmetrically arranged guide plate 701. The guide plate 701 is connected to the intermittent conveying component 6 of the feeding mode to realize feeding. The bottom of the storage hopper 7 is symmetrically provided with a rotating groove 702. An adjustable intermittent discharge component 8 is rotatably installed in the rotating groove 702 on both sides. This directly addresses the pain points of the traditional discharge port being non-adjustable and discontinuous discharge, and provides a structural basis for adapting to different pipe diameters and realizing controllable discharge.

[0046] like Figure 3 As shown, the mode switching component 4 includes a track limiting frame 401, a fixed base 402, and a hydraulic push rod 403. Two track limiting frames 401 are provided and arranged symmetrically on the left and right. Sliding limiting rod one 404 and sliding limiting rod two 405 are fixedly connected through both sides of the fixed base 402. The lengths of both sliding limiting rod one 404 and sliding limiting rod two 405 are not less than the length of the storage hopper 7, ensuring that the two limiting rods always maintain limiting contact with the track limiting frame 401 when the material blocking component 5 is adjusted. Sliding limiting rod one 404 is located in front of sliding limiting rod two 405. The hydraulic push rod 403, as a power source, can provide smooth, high-thrust linear motion, which is very suitable for attitude adjustment under heavy loads.

[0047] The bottom end of the hydraulic push rod 403 is rotatably connected to the outer wall of the middle section of the fixed rod 301, and the movable top end of the hydraulic push rod 403 is rotatably connected to the outer wall of the second sliding limit rod 405. The second sliding limit rod 405 and the first sliding limit rod 404 slide along the inner limit frame 401 to achieve the tilting, rising, and resetting of the fixed seat 402. The second sliding limit rod 405, the first sliding limit rod 404, and the track limit frame 401 constitute a statically indeterminate support structure, ensuring that the fixed seat 402 and the intermittent conveying component 6 on it do not twist or jam during movement, and the movement trajectory has excellent rigidity.

[0048] like Figure 4As shown, the track limiting frame 401 has two thrust limiting holes, 4011 and 4012, on its lower side wall along a line parallel to the base plate 1. A rotation limiting hole 4013 is formed at the top front end of the track limiting frame 401. The rotation limiting hole 4013 is formed with the front end of the thrust limiting hole 4012 as its rotation fulcrum and the distance between the sliding limiting rods 404 and 405 as its radius. A rising limiting hole 4015 is formed at a 45° angle at the front end of the track limiting frame 401. A rising limiting hole 4014 is formed at a similar angle at the front end of the rotation limiting hole 4013. The rising limiting hole 4014 and the rising limiting hole 4015 have the same angle of inclination. This results in the track limiting frame 401 exhibiting a three-stage trajectory of thrusting, rotating, and rising.

[0049] The sliding limit rod 405 is in sliding engagement with the first push limit hole 4011, the rotation limit hole 4013, and the first rise limit hole 4014. The sliding limit rod 404 is in sliding engagement with the second push limit hole 4012 and the second rise limit hole 4015. By using mechanical track hard limiting to guide and restrict the simple linear motion of the hydraulic push rod 403, the design of a predetermined composite motion trajectory is achieved, making the device more reliable, lower in cost, and stronger in anti-interference capability, ensuring absolute precision at the endpoint position of each mode switch.

[0050] During the advancement process, the hydraulic push rod 403 pushes the fixed base 402 forward, the sliding limit rod 404 slides along the advancement limit hole 4012, and the sliding limit rod 405 slides along the advancement limit hole 4011, thereby driving the intermittent conveying component 6 to move forward to reserve space for subsequent inclined docking and avoid interference with the storage hopper 7. When the translation reaches its most extreme point, the hydraulic push rod 403 continues to push, at which point the rotation stage begins. With the sliding limit rod 404 as the fulcrum, the sliding limit rod 405 slides along the rotation limit hole 4013. Intermittent conveying component 6 begins to undergo precise tilt angle changes in preparation for docking with guide ramp 701. Next, hydraulic push rod 403 continues to push, entering the rising stage. Sliding limit rod 1 404 slides tilted along rising limit hole 2 4015, and sliding limit rod 2 405 slides tilted along rising limit hole 1 4014. Intermittent conveying component 6 finally docks precisely with guide ramp 701, completing the locking of the feeding posture and completing the switching of the feeding mode. When it is necessary to switch to the discharge mode, the extension rod of hydraulic push rod 403 only needs to be reset.

[0051] like Figure 4As shown, the baffle assembly 5 includes a first baffle plate 501 symmetrically arranged on the left and right, a slide rail 504 fixedly installed on the upper surface of the base plate 1, and a movable limiting shell 506. The slide rail 504 and the movable limiting shell 506 are arranged in parallel. There are two slide rails 504, which are located on the front and rear sides of the movable limiting shell 506 respectively. The rear end of the first baffle plate 501 is provided with a second baffle plate 502. The side walls of the second baffle plate 502 are slidably connected to the inner side wall of the storage hopper 7. The first baffle plate 501 and the second baffle plate 502 form protection on both sides of the steel pipe conveying path to prevent the steel pipe from rolling down. At the same time, they ensure that the steel pipe remains neat when it is piled up, providing the necessary conditions for orderly discharge.

[0052] Slider 503 is fixedly connected to the front and rear bottom ends of the first baffle plate 501. The slider 503 is slidably connected to the adjacent slide rail 504. Movable block 505 is fixedly connected to the middle bottom end of the first baffle plate 501. Bidirectional threaded screw 507 is rotatably connected through the inner walls of both sides of the movable limiting shell 506. The outer wall of the bidirectional threaded screw 507 is threadedly connected to the side wall of the movable block 505. Motor 508 is fixedly installed on the side wall of the movable limiting shell 506. The output end of motor 508 is fixedly connected to one end of the bidirectional threaded screw 507. When conveying the steel pipe, the bidirectional threaded screw 507 is driven by motor 508 to make the movable blocks 505 on both sides move synchronously towards or away from each other, thereby adjusting the distance between the first baffle plate 501 and the second baffle plate 502 to match steel pipes of different lengths. The slider 503 slides with the slide rail 504 to ensure the linear motion accuracy and stability of the baffle plate during the adjustment process and prevent jamming.

[0053] The side walls of the baffle plate 501 are provided with mounting holes 509 that are adapted to the shape of the track limiting frame 401. The two track limiting frames 401 are fixedly installed in the mounting holes 509 on both sides. The mounting holes 509 on the baffle plate 501 fix the track limiting frame 401, so that the width of the entire mode switching component 4 and the intermittent conveying component 6 can be adjusted together with the baffle to ensure that the conveying channel is always centered and to prevent the steel pipe from falling due to the shift of the center of gravity during conveying. At the same time, the two track limiting frames 401 are fixedly installed in the mounting holes 509 on both sides, integrating the mode switching component 4, which is a motion execution component, and the structural load-bearing component, into the baffle component 5, simplifying the overall frame and enhancing the structural compactness and overall rigidity.

[0054] like Figure 5As shown, the intermittent conveying assembly 6 includes a U-shaped housing 601 and a U-shaped housing 602. The bottom end of the U-shaped housing 601 is fixedly connected to the upper surface of the fixed base 402. The U-shaped housing 602 is located inside the U-shaped housing 601. The U-shaped housing 601 and the U-shaped housing 602 are arranged parallel to each other. Right-angle serrated grooves 606 are arranged at equal intervals on the top of the U-shaped housing 601 and the U-shaped housing 602. Whether in a horizontal or inclined state, the steel pipe can be supported and intermittently conveyed through the right-angle serrated grooves 606 on the top, preventing it from rolling randomly in an inclined or horizontal state.

[0055] Movable rods 603 are rotatably connected to the front and rear ends of the left and right sidewalls of the second U-shaped shell 602. The four movable rods 603 are arranged in the same direction. A rotating rod 604 is fixedly connected to the side of each movable rod 603 near the inner sidewall of the first U-shaped shell 601. The sidewall of each rotating rod 604 is rotatably connected through the sidewall of the first U-shaped shell 601. A second motor 605 is fixedly installed on the outer sidewall of the first U-shaped shell 601. The output end of the second motor 605 is fixedly connected to one end of the rotating rod 604. When conveying the steel pipe, the second motor 605 drives the rotating rod 604, which in turn causes the inner U-shaped shell 602 to reciprocate relative to the outer U-shaped shell 601 via the movable rods 603.

[0056] The right-angle serrated grooves 606 of U-shaped housing 1 601 and U-shaped housing 2 602 are initially aligned to support the steel pipe. When U-shaped housing 2 602 moves forward or backward, the two rows of serrated grooves are misaligned, and the groove depth becomes shallower, causing the steel pipe that was originally stuck in the groove to roll down one position. Then U-shaped housing 2 602 resets, the two grooves are aligned again, and the next steel pipe is supported. This cycle is repeated to achieve intermittent, single-pipe drop, thereby realizing controllable and discrete step conveying. This is more conducive to the separation and positioning of single steel pipes than continuous rolling conveying.

[0057] like Figures 6-9 As shown, the adjustable intermittent discharge assembly 8 includes a limiting plate 801 rotatably mounted on the inner wall of the rotating groove 702 and a servo electric cylinder 802 vertically fixedly mounted on the side wall of the storage hopper 7. The two limiting plates 801 are symmetrically arranged. A connecting block 803 is fixedly connected to the bottom of the movable end of the servo electric cylinder 802. Connecting rods 804 are rotatably connected to both sides of the connecting block 803. A rotating disk 805 is fixedly connected to one end of each limiting plate 801 near the connecting rod 804 through the side wall of the rotating groove 702. The other end of each connecting rod 804 is rotatably connected to the outer wall of the eccentric part of the adjacent rotating disk 805. During adjustment, the servo electric cylinder 802 provides precise position control, and drives the two rotating disks 805 to rotate through the connecting rod 804, thereby causing the two limiting plates 801 to open and close synchronously like a "gate". This achieves stepless, electric adjustment of the discharge port width, which can quickly adapt to steel pipes of different diameters and has high adjustment accuracy.

[0058] The inner sidewalls of the limiting plate 801 are all fixed with protective plates 806. The bottom end of the limiting plate 801 is provided with a rotating groove 807. The bottom ends of the two rotating grooves 807 are rotatably connected to the intermittent feeding mechanism 808. The protective plate 806 is located above the intermittent feeding mechanism 808. The protective plate 806 protects the rotation of the intermittent feeding mechanism 808 and prevents the top gap of the intermittent feeding mechanism 808 from contacting the steel pipe, causing jamming and affecting the normal operation of the intermittent feeding mechanism 808.

[0059] like Figure 10 As shown, the intermittent feeding mechanism 808 includes an arc-shaped feeding plate 8081 symmetrically rotatably installed on the inner wall of the two rotating slots 807 on both sides, and a bracket 8084 symmetrically fixed on the outer wall of the two limiting plates 801 on both sides. The upper and lower ends of the arc-shaped feeding plate 8081 are provided with slots 8082. Rolling rods 8083 are rotatably connected between the inner walls of the two sides of the slots 8082. A bracket 8085 is fixedly connected to the side wall of the arc-shaped feeding plate 8081 near the adjacent bracket 8084. A servo electric cylinder 8086 is rotatably connected between the adjacent bracket 8084 and the bracket 8085 to control the opening and closing of the bottom outlet of the storage hopper 7 and the feeding rhythm. It works in conjunction with the intermittent conveying component 6 to realize active and flexible single-piece feeding.

[0060] During operation, the servo electric cylinder 8086 drives the two arc-shaped material-pushing plates 8081 on both sides to swing back and forth. When material needs to be discharged, the two arc-shaped material-pushing plates 8081 rotate and swing synchronously, the lower half opens, and the rolling rod 8083 at its end gently "pushes out" the bottommost steel pipe, while the upper half tends to close, blocking the upper steel pipe. After the servo electric cylinder 8086 resets, the next material discharge cycle can begin. This achieves single-piece, timed, and low-impact material discharge, solving the problems of congestion, uneven material distribution, and impact that are easily caused by gravity-type material discharge. The rolling rod 8083 reduces friction with the steel pipe, improving the smoothness of material discharge.

[0061] The working principle of this embodiment is as follows: When in use, the universal wheel 2 pushes the device to the electric vehicle parts storage area or the discharge port of the previous process.

[0062] Switch the equipment to feeding mode and activate the hydraulic push rod 403 via the control panel 9. The hydraulic push rod 403 pushes the fixed base 402 forward. The sliding limit rod 404 slides along the second push limit hole 4012, and the second sliding limit rod 405 slides along the first push limit hole 4011. This causes the intermittent conveying component 6 to move forward to reserve space for subsequent tilt docking. When the movement reaches its extreme, the hydraulic push rod 403 continues to push, and the rotation stage begins. With the first sliding limit rod 404 as the fulcrum, the second sliding limit rod 405 slides along the rotation limit hole 4013. The intermittent conveying component 6 begins to undergo precise tilt angle changes. Next, the hydraulic push rod 403 continues to push, entering the rising stage. The first sliding limit rod 404 tilts along the second rising limit hole 4015, and the second sliding limit rod 405 tilts along the first rising limit hole 4014. The intermittent conveying component 6 finally precisely docks with the guide plate 701, completing the locking of the feeding posture.

[0063] Next, the spacing of the guard plates is adjusted according to the length of the steel pipe. The motor 508 drives the bidirectional threaded screw 507 to make the movable blocks 505 on both sides move synchronously towards or away from each other, thereby adjusting the spacing of the guard plates 501 and 502 on both sides. The guard plates 501 and 502 form protection on both sides of the steel pipe conveying path to prevent the steel pipe from rolling down, and at the same time ensure that the steel pipe remains neat when stacked, providing the necessary conditions for orderly discharge.

[0064] Servo electric cylinder 802 pushes connecting block 803, which in turn drives two rotating disks 805 to rotate via connecting rod 804, thereby causing two limiting plates 801 to close like a "gate" and block the discharge port of storage hopper 7.

[0065] During feeding, the intermittent conveying component 6, which is in an inclined state, starts the second motor 605. The output shaft of the second motor 605 drives the rotating rod 604 in the opposite direction. Through the movable rod 603, the inner U-shaped shell 602 swings back and forth relative to the outer U-shaped shell 601. The right-angle serrated grooves 606 of the first U-shaped shell 601 and the second U-shaped shell 602 are initially aligned to support the steel pipe. When the second U-shaped shell 602 moves forward or backward, the two rows of serrated grooves are misaligned and the groove depth becomes shallower, causing the steel pipe that was originally stuck in the groove to roll down one position. Then the second U-shaped shell 602 resets, the two grooves are aligned again, and the next steel pipe is supported. This cycle is repeated to realize the intermittent, single-pipe drop of the steel pipe until the bottom steel pipe is conveyed to the top. The steel pipe rolls down into the storage hopper 7 in an orderly manner along the guide inclined plate 701 for temporary storage.

[0066] Afterwards, the equipment is transferred to the electric vehicle assembly line or welding station, the equipment is switched to the discharge mode, the hydraulic push rod 403 drives the telescopic rod to reset, and the intermittent conveying component 6 is pulled to the bottom of the storage hopper 7;

[0067] According to the diameter of the steel pipe, the servo electric cylinder 802 drives the two limiting plates 801 to open and close synchronously to adjust the width of the discharge port. When discharging, the two servo electric cylinders 8086 simultaneously drive the two arc-shaped material-pulling plates 8081 on both sides to swing back and forth. The two arc-shaped material-pulling plates 8081 on both sides rotate and swing synchronously. The lower half opens, and the rolling rod 8083 at the end gently "pushes out" the bottom steel pipe, which falls on the right-angle sawtooth groove 606. The upper half tends to close, blocking the upper steel pipe. After the servo electric cylinder 8086 resets, it can enter the next feeding cycle.

[0068] When feeding the steel pipes, motor 605 drives the rotating rod 604 in the forward direction. Through the movement of the sawtooth groove, the steel pipes at the end are conveyed one by one to the front end and rolled downwards to the target position, thus completing the conveying.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
