Description

Technical Field

[0001] This invention relates to the field of magnetization technology, and in particular discloses a fully automatic magnetization device for neodymium iron boron magnets. Background Technology

[0002] Existing NdFeB magnet magnetization equipment often uses manual labor or simple tooling to complete magnet feeding, magnetization, unloading, and tray stacking operations, resulting in low automation and limited production efficiency. Traditional magnetization support structures are unable to achieve reliable lateral positioning and smooth ejection of NdFeB magnets during magnetization, easily leading to magnet displacement, jamming, and damage from impacts. Conventional automatic tray stacking mechanisms are prone to causing the tray to pull and bounce or shift during the negative pressure detachment of the suction cups during tray lifting and holding. Furthermore, the unidirectional stacking self-locking structure of the trays is complex and has high processing and assembly costs. At the same time, the material transfer buffering, magnetization track docking and pushing, and precise unloading clamping space reservation after material transfer at the magnetization station lack an integrated structure that is compatible and coordinated, making it difficult to stably adapt to the production requirements of continuous automated magnetization, unloading, and tray stacking of NdFeB magnets. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a fully automatic magnetization device for neodymium iron boron magnets.

[0004] To achieve the above objectives, the present invention provides a fully automatic magnetization device for neodymium iron boron magnets, comprising a magnetic carrier, a feeding mechanism, a buffer assembly, a magnetization assembly, a pushing assembly, and a tray unloading assembly. The magnetic carrier holds a magnet to be magnetized. The magnetic carrier is conveyed to the buffer assembly for temporary storage via the feeding mechanism. An external robot moves the magnetic carrier from the buffer assembly to the magnetization assembly for magnetization. After magnetization, the external robot moves the magnetic carrier carrying the magnetized magnet to the pushing assembly. The pushing assembly pushes the magnetized magnet inside the magnetic carrier outward for unloading. The external robot then transfers the unloaded magnetized magnet to the tray unloading assembly for stacking. The magnetic carrier includes a body, a limiting plate, and a pusher. The body has a through groove along its length and a first opening at one end that communicates with the through groove. The limiting plate is mounted on the body and has a guide groove along its length, which communicates vertically with the through groove. The pusher includes a first push block and a second push block perpendicularly disposed on the first push block. The first push block is slidably accommodated at the end of the through groove away from the first opening. The magnetized part is accommodated inside the through groove and located on the side of the first push block closer to the first opening. The second push block protrudes from the upper surface of the limiting plate via the guide groove. The pushing assembly pushes and pulls the second push block, causing the first push block to slide along the through groove, so that the first push block pushes the magnetized part out of the first opening, thereby achieving automatic separation and unloading of the magnetized part from the magnetic carrier.

[0005] Shoulders are provided at both ends of the guide groove. The shoulders are used to limit the sliding stroke of the second push block. By blocking the second push block, the sliding range of the first push block is indirectly limited, preventing the pusher from coming out of the first opening along the through groove.

[0006] During operation, the component to be magnetized is pre-placed in the through-slot of the magnetic carrier body. After being conveyed and temporarily stored by the feeding mechanism and buffer assembly, the magnetic carrier is transferred by an external robotic arm to the magnetization assembly for magnetization. The magnetized magnetic carrier is then transferred by the robotic arm to the pushing assembly station. A second pusher in the guide slot, guided by a push-pull limiting plate, moves the first pusher, pushing the magnetized component out of the first opening in the through-slot for unloading. The robotic arm then transfers the unloaded magnetized component to the material tray unloading assembly for stacking. The equipment utilizes shoulders at both ends of the guide slot to... The second pusher provides physical limitation and indirectly constrains the sliding stroke of the first pusher. While ensuring that the magnetized part can be ejected smoothly and the material can be automatically separated and unloaded, it effectively prevents the pusher from slipping out. The structure is simple and compact, and there is no need to add additional complex limiting components. It can realize the stable reset and cyclic reuse of the pusher, effectively eliminating problems such as material jamming, equipment downtime, parts wear and loss caused by the pusher coming out. It significantly improves the overall stability and continuity of equipment operation, reduces equipment maintenance costs, and effectively improves the automation production efficiency of the entire process of magnetizing, unloading and collecting neodymium iron boron magnets.

[0007] The magnetic support components, limiting plates, and pushing components are all made of non-magnetic materials, which will not divert the magnetizing flux or change the distribution of the magnetizing magnetic field.

[0008] The width of the guide groove is smaller than the width of the part to be magnetized, so that the limiting plate blocks the part to be magnetized and prevents the part to be magnetized from coming out of the guide groove.

[0009] The magnetic support component also includes a sealing component. The main body has second openings on both sides, which are connected to the through-groove. The sealing component is slidably mounted on the main body and includes a first protrusion, a first protrusion at each end of the first protrusion, and a second protrusion. The first protrusion has a clearance groove to allow movement of the pusher. The direction of movement of the sealing component is perpendicular to the direction of sliding of the pusher. When the first protrusion protrudes from the side of the main body and the second protrusion is flush with the second opening on one side of the main body, the clearance groove is misaligned with the through-groove, and the first protrusion laterally seals and limits the magnetized component in the through-groove. When the second protrusion protrudes from the side of the main body and the first protrusion is flush with the second opening on the other side of the main body, the clearance groove is aligned with the through-groove, allowing the first pusher to eject the magnetized component from the first opening of the through-groove for unloading.

[0010] When this equipment is working, the part to be magnetized is placed in the through groove of the main body, and the sealing part slides and adjusts its position along the direction perpendicular to the sliding of the pusher. During the magnetization stage, the sealing part slides until the first protrusion protrudes from the side of the main body and the second protrusion is flush with the second opening on one side of the main body. At this time, the clearance groove and the through groove are misaligned, and the first protrusion forms a lateral sealing limit on the part to be magnetized in the through groove, preventing the part to be magnetized from shifting laterally or falling out, and ensuring the stability of the magnetization position. During the unloading stage, the sealing part switches to the state where the second protrusion protrudes from the side of the main body and the first protrusion is flush with the second opening on the other side of the main body. The clearance groove and the through groove are aligned, the lateral obstruction is released, and the first pusher of the pusher can push the magnetized part out of the first opening for unloading. This sealing part adopts a single-component sliding switching sealing / It avoids two working conditions, has a simple structure, and can realize lateral locking and unloading simultaneously by relying solely on lateral sliding. The positioning is reliable and the switching action is simple. It can prevent the lateral movement of the part to be magnetized, improve the consistency of magnetization and the smoothness of unloading, and adapt to the continuous operation requirements of automated magnetization and unloading of neodymium iron boron magnets.

[0011] The first and second protrusions are respectively vertically arranged at both ends of the first protrusion. The length of the protrusion is greater than the thickness of the first protrusion. The contact length between the first and second protrusions and the side of the body is larger, so the sealing part is less likely to deviate or get stuck when it slides laterally, and the positioning stability is better.

[0012] The buffer assembly includes a first driving component, a conveyor belt connected to the output end of the first driving component, and a material feeding assembly disposed on the side of the conveyor belt. The conveyor belt is arranged parallel to the magnetization assembly. A temporary storage plate is provided on the side of the conveyor belt near the magnetization assembly. The temporary storage plate is used to receive the magnetic carriers conveyed to the position by the conveyor belt. The material feeding assembly is used to push the magnetic carriers on the conveyor belt onto the temporary storage plate for temporary storage and positioning, so that they can be grasped and transferred to the magnetization assembly by an external robot arm.

[0013] The feeding assembly includes a first sliding guide rail, a first support frame reciprocatingly sliding on the first sliding guide rail, a rotary motor fixed on the first support frame, a feeding plate connected to the output end of the rotary motor, and a second driving member for driving the first support frame to slide. The feeding plate is suspended above the conveyor belt and includes a first plate and a second plate on the first plate. The second plate is used to abut against the side of the magnetic support member. The second driving member drives the first support frame to slide along the first sliding guide rail, causing the second plate to push the magnetic support member laterally to the temporary storage plate for positioning. After the magnetic support member is pushed into place, the rotary motor drives the feeding plate to rotate and lift, separating it from the conveyor belt surface. The second driving member drives the first support frame to return and slide back to reset. Then, the rotary motor drives the feeding plate to rotate and press down to reset to the feeding position, waiting for the next feeding operation.

[0014] During operation, the first drive unit drives the conveyor belt to transport the magnetic carrier containing the part to be magnetized. After the magnetic carrier is transported to the corresponding position, the second drive unit drives the first support frame to slide along the first sliding guide rail, so that the second plate on the material feeding plate abuts against the side of the magnetic carrier, pushing the magnetic carrier laterally onto the temporary storage plate for temporary storage and positioning, which is convenient for external robotic arms to grasp and transfer to the magnetization assembly. After the magnetic carrier is pushed into place, the rotary motor drives the material feeding plate to rotate and lift to detach from the conveyor belt surface. Then, the second drive unit drives the first support frame to return and slide back to reset. After that, the rotary motor drives the material feeding plate to rotate and press down to return to the feeding station to wait for the next operation. This feeding assembly adopts a sliding push combined with a rotation lifting and avoidance structure, which ensures reliable push and positioning. When the material feeding plate is lifted during the return stroke, it will not interfere with the continuous feeding of the conveyor belt. It can stably complete the transfer and temporary storage of the magnetic carrier, ensure the orderly supply of materials to the magnetization station, and facilitate continuous automated production of the equipment.

[0015] The magnetization assembly includes a magnetization component and a propulsion component. The magnetization component includes a magnetization base and a magnetization track. The magnetization track includes a first track, a second track, and a third track integrally formed sequentially. The first track connects to the discharge end of the buffer component, the second track is located in the magnetization station inside the magnetization base, and the third track connects to the loading end of the pusher component. The propulsion component includes a third drive component, a pusher guide rail, a second support frame, and a pusher component. The second support frame is slidably mounted on the pusher guide rail and connected to the output end of the third drive component. The pusher component is fixed on the second support frame and is located at the end of the first track away from the second track. The third drive component drives the second support frame to slide back and forth along the pusher guide rail, which in turn drives the pusher component to push the magnetic carrier component carrying the component to be magnetized on the first track to the magnetization station of the second track to complete the magnetization. After magnetization is completed, the pusher component continues to push the magnetic carrier component to the third track for temporary storage, waiting for the external robot arm to transfer it to the next process.

[0016] During operation, the magnetic carrier, delivered by the buffer component, is fed into the first track of the magnetization track. The third drive component drives the second support frame to slide along the magnetic pusher rail, which in turn drives the pusher to push the magnetic carrier on the first track to the magnetization station inside the magnetization seat on the second track to complete the magnetization. After magnetization, the pusher continues to push the magnetic carrier to the third track for temporary storage, waiting for the external robot to transfer it to the pusher component. The magnetization track adopts an integrated structure of the first, second, and third tracks, with high track docking accuracy and less prone to misalignment. Together with the pusher component, it realizes the smooth feeding, fixed-point magnetization, and temporary storage of the magnetic carrier. The material conveying is continuous and can stably connect the preceding and following processes, improving the automation continuity and positioning consistency of the NdFeB magnet magnetization process.

[0017] The pushing assembly includes a third support frame, a first pushing assembly, a second pushing assembly, and a stop block mounted on the third support frame. When the magnetic carrier carrying the magnetized component is transferred to the third support frame station, the first pushing assembly faces one end of the top pushing component of the magnetic carrier, and the stop block abuts against and is limited to the first opening end of the magnetic carrier, thus fixing and positioning the magnetic carrier. The second pushing assembly is located on the side of the magnetic carrier and is used to drive the sealing component to slide laterally, so that the clearance groove of the sealing component is aligned and connected with the through groove of the main body. After alignment, the first pushing assembly pushes and pulls the second pushing block of the top pushing component, causing the first pushing block to slide along the through groove, pushing the magnetized component inside the through groove out from the first opening, thus completing the automatic unloading operation of the magnetized component.

[0018] The abutment block includes a main body, a first limiting protrusion and a second limiting protrusion disposed on the main body. The first limiting protrusion and the second limiting protrusion are arranged in parallel and spaced apart, and together they form a feeding groove that is aligned and connected with the through groove. The height of the first limiting protrusion and the second limiting protrusion is less than the height of the magnetized part, so that when the magnetized part is pushed out of the feeding groove, the upper surface of the magnetized part is higher than the upper surface of the two sets of limiting protrusions, avoiding obstruction and interference by the limiting protrusions, and reserving sufficient clamping space for the external robot arm.

[0019] The magnetic carrier bearing the magnetized component is transferred to the third support frame station. The abutment block abuts against the first opening end of the magnetic carrier to complete the positioning. The first pushing component aligns with one end of the pusher component, and the second pushing component drives the sealing component to slide laterally, so that the clearance groove of the sealing component is aligned and connected with the through groove of the main body. Then, the first pushing component pushes and pulls the second pusher block of the pusher component, causing the first pusher block to slide along the through groove, and ejecting the magnetized component through the first opening for unloading. The abutment block forms a feeding groove that is aligned and connected with the through groove through the first and second limit protrusions set in parallel intervals. The height of the two sets of limit protrusions is less than the height of the magnetized component. After the magnetized component is ejected from the feeding groove, its upper end surface is higher than the upper end surface of the limit protrusions, so it will not obstruct or interfere with the external robot arm, and a reliable clamping space is reserved. The entire pushing component can complete the carrier positioning, sealing component clearance, and magnet ejection unloading actions in sequence. The process is well coordinated, the unloading is stable and convenient for the robot arm to pick up the material, ensuring smooth connection of automated operation.

[0020] The material tray unloading assembly includes a material tray track, a tray dropping assembly, and a tray picking assembly. The tray dropping assembly and the tray picking assembly are respectively located at both ends of the material tray track, and a gap is formed between the tray dropping assembly and the tray picking assembly. The tray dropping assembly is used to drop empty material trays downward onto the material tray track. The empty material trays are transported to the gap position via the material tray track to receive the magnetized parts transferred by the external robot. The filled full material trays are transported to the tray picking assembly station via the material tray track, and the tray picking assembly completes the automatic stacking and receiving operation of the full material trays.

[0021] The material tray track includes a third guide rail, a first conveyor belt and a second conveyor belt arranged parallel to the third guide rail. The first conveyor belt and the second conveyor belt are symmetrically spaced on the left and right, and a hollow part is formed between the first conveyor belt and the second conveyor belt. The material tray is supported on the first conveyor belt and the second conveyor belt on both sides respectively, and the material tray is moved by the synchronous operation of the first conveyor belt and the second conveyor belt.

[0022] During operation, the tray dropping assembly lowers empty trays onto the first and second conveyor belts of the tray track. The empty trays are then moved to the interval section by the two synchronously operating and symmetrically spaced conveyor belts to receive magnetized parts transferred by the external robotic arm. The filled trays are then conveyed by the conveyor belts to the tray retrieval assembly station for automatic stacking and collection. A hollow section is formed between the first and second conveyor belts, which provides passage space for the pushing structure of the tray dropping and retrieval station below. The trays are supported and conveyed by belts on both sides, resulting in smooth movement and a simple structure. This allows for stable and continuous automated operation of empty tray supply, material reception, and full tray stacking and collection.

[0023] The tray-dropping assembly includes a fourth support frame, four sets of first baffles mounted on the fourth support frame, four sets of clamping members, and a first push-drive member. A first discharge hole is formed in the center of the fourth support frame, opposite to a hollowed-out section. The first push-drive member is located below the hollowed-out section. The four sets of first baffles are arranged around the first discharge hole and enclose a first receiving chamber for stacking and storing empty trays. Each first baffle has a first clearance hole communicating with the first receiving chamber. The four sets of clamping members are located on the sides of the four sets of first baffles and can pass through the opposite sides of the first baffles. The first clearance hole of the first baffle extends into the first receiving cavity to clamp and position the empty material tray from all sides. When the empty material tray is unloaded, the first push drive moves upward and approaches the bottom of the stacked empty material trays, leaving a thickness gap for the falling of a single set of empty material trays. Then, the four sets of clamping members retract and exit the first receiving cavity, and the bottom single set of empty material trays falls and is supported by the first push drive. The remaining stacked empty material trays are clamped and positioned again by the clamping members. Finally, the first push drive moves downward, driving the single set of empty material trays through the first dropping hole and falling onto the tray track, completing the single empty material tray unloading.

[0024] Multiple empty trays are stacked and stored in a first receiving cavity formed by four sets of first baffles. The clamping members around the perimeter pass through the first clearance holes to laterally clamp and position the stacked empty trays. When unloading empty trays, the first push drive moves upward to approach the bottom of the stacked empty trays and leaves a thickness gap for the single empty tray to fall. Then, the four sets of clamping members retract and exit the first receiving cavity, and only the bottom empty tray falls onto the first push drive. The remaining stacked empty trays are then re-clamped and fixed by the clamping members. Then, the first push drive moves downward, driving the single empty tray to fall through the first discharge hole onto the tray track to complete a single unloading. This tray unloading assembly adopts a method of clamping from all four sides and lifting and releasing with the push drive, which can achieve the separation and dropping of only one empty tray at a time, effectively preventing multiple trays from sticking together and falling together. The tray unloading action is reliable and the separation is accurate, which can stably and continuously supply empty trays to the tray track, ensuring the continuous and automated operation of subsequent material filling processes.

[0025] The tray-retrieving assembly includes a fifth support frame, four sets of second baffles mounted on the fifth support frame, four sets of backstop components, and a second push-drive component. The fifth support frame has a second discharge hole in its center, which is vertically aligned with the hollowed-out portion. The second push-drive component is located below the hollowed-out portion. The four sets of second baffles are arranged around the second discharge hole to form a second accommodating chamber for stacking and storing full trays. Each second baffle has a second clearance hole communicating with the second accommodating chamber. The four sets of backstop components are respectively located on the outer sides of the four sets of second baffles, and each backstop component can pass through the corresponding second clearance hole. The hole extends into the second receiving chamber to support the stacked full pallets. When the full pallets are being stacked, a single set of full pallets carrying the magnetized components is moved along the pallet track to the position above the pallet unloading assembly. The second push drive pushes the full pallet upward, causing it to move upward into the second receiving chamber. During the upward movement of the full pallet, it presses against the backstop assembly, triggering the backstop assembly to swing inward to allow the full pallet to pass smoothly. After the full pallet has completely passed the backstop assembly, the backstop assembly resets and extends, tilting to support the full pallet, thus limiting the stacking of the full pallets. Subsequently, the second push drive moves downward to reset, waiting for the next set of full pallets to be pushed and stacked.

[0026] The filled tray is moved along the tray track to the station above the tray retrieval assembly. The second push drive pushes the tray upward, allowing it to move upward through the second discharge hole into the second receiving chamber formed by four sets of second baffles. During the upward movement of the tray, the backstop assembly is squeezed, and the backstop assembly is forced to swing inward to allow the tray to pass smoothly. After the tray has completely passed the backstop assembly, the backstop assembly returns to its original position, extends, and tilts to support the tray, completing the stacking limit of the tray. Then the second push drive returns to its original position to prepare for the next stacking operation. This tray retrieval assembly relies on the one-way passage and reverse support self-locking characteristics of the backstop assembly to only allow the trays to stack upward and prevent the trays from falling back. The structure is simple and reliable, and it can realize the automatic and orderly stacking of trays, which is suitable for the needs of automated continuous material collection.

[0027] The anti-reverse assembly includes a fixed block, a first rotating block, a connecting block, a connecting rod, a first rotating shaft, and a second rotating shaft. The fixed block includes a first block and a second block perpendicularly disposed on the first block. The first rotating block has a first groove and a second groove on its two sides. The connecting block includes an integrally formed first main body and a second main body. The first main body has a receiving hole, and the second main body has a through hole. The opening directions of the receiving hole and the through hole are perpendicular to each other. One end of the connecting rod is fixed to the first block, and the other end is fixedly connected to the receiving hole of the first main body, so that the connecting block is fixed as a whole and does not rotate relative to each other. The side walls of the first groove have a first rotating hole and a second rotating hole, respectively. The first rotating shaft passes through the first rotating hole, the through hole, and the second rotating hole in sequence, allowing the first rotating block to swing relative to the connecting block around the first rotating shaft. The second block has a first groove and a second rotating shaft. The second groove has three rotating holes. The second rotating shaft passes through the fourth, third, and fifth rotating holes in sequence, allowing the first rotating block to swing relative to the fixed block around the second rotating shaft. The first and second rotating shafts are arranged parallel to each other, and the distance from the first rotating shaft to the first block is less than the distance from the second rotating shaft to the first block, so that the first rotating block maintains an outward tilted supporting posture under normal conditions. When the second push drive pushes the full material tray upward, the side wall of the full material tray presses against the first rotating block, driving the first rotating block to swing inward around the first and second rotating shafts simultaneously to avoid collision, allowing the full material tray to move upward into the second accommodating chamber. After the full material tray moves upward and loses contact, the first rotating block automatically returns to the tilted posture, stably supporting the current full material tray and all the full material trays stacked above, realizing the stacking function of the full material tray moving upward and self-locking downward.

[0028] During operation, the backstop assembly relies on the first and second rotating shafts, which are parallel to each other and at unequal distances from the first block, to constrain the first rotating block. Under normal conditions, the first rotating block maintains an outward tilted supporting posture. When the second push drive pushes the full material tray upward, the side wall of the full material tray presses against the first rotating block, causing the first rotating block to swing inward synchronously around the first and second rotating shafts to avoid obstruction, allowing the full material tray to smoothly move upward into the second receiving chamber. After the full material tray is no longer in contact, the first rotating block automatically returns to its tilted posture, stably supporting the current full material tray and all the full material trays stacked above it. This achieves a unidirectional stacking function where the full material tray can only pass upward and is self-locking downward. This dual-shaft linkage structure has a stable layout and smooth swing, which can reliably achieve unidirectional stacking of full material trays to prevent them from falling, ensuring that the tray retrieval assembly can continuously and stably complete the automatic stacking operation of full material trays.

[0029] The opening width of the hollow part is greater than the diameter of the first and second material dropping holes, so that the pushing stroke of the push drive and the falling stroke of the material tray are completely unobstructed, ensuring smooth and unimpeded material dropping of empty trays and pushing and stacking of full trays.

[0030] The front end of the pusher is provided with a soft pushing pad. The soft pushing pad contacts the end of the magnetic support component and pushes it, avoiding deformation of the support component and collision of the component to be magnetized caused by rigid pushing. At the same time, it buffers the pushing impact force and reduces the operating noise of the equipment.

[0031] The push drive component includes a push cylinder, a push plate disposed at the output end of the push cylinder, and a suction cup disposed on the push plate. The suction cup is a floating buffer negative pressure suction cup, which includes a plate body and a flexible lip. The plate body is fixed to the bottom surface of the push plate, and an adsorption cavity is provided inside the plate body. The flexible lip is arranged around the lower port of the adsorption cavity. The negative pressure air passage is connected to the adsorption cavity, and a pressure relief microchannel is provided in parallel with the negative pressure air passage. When the negative pressure air source is closed, the pressure relief microchannel introduces normal pressure air into the adsorption cavity to break the vacuum. Before the push cylinder moves downward, the vacuum adsorption force is broken to prevent the suction cup from pulling the material plate and causing bumps and displacement.

[0032] The suction cup has a simple structure and is easy to assemble. It relies on the pressure relief microchannel to introduce normal pressure air into the adsorption chamber in advance to break the vacuum after the negative pressure air source is turned off. Before the push cylinder moves down, the adsorption force is released first to avoid the suction cup directly tearing the material tray and causing bumps and displacement. This ensures that the lifting and releasing action of the material tray in the tray dropping and tray picking process is stable and controllable.

[0033] The beneficial effects of this invention are as follows: By setting up a magnetic support component, a feeding mechanism, a buffer assembly, a magnetizing assembly, a pushing assembly, and a tray unloading assembly to work together, this invention achieves fully automated operation of neodymium iron boron magnets, including automatic feeding, buffer storage, precise magnetization, automatic unloading, automatic tray loading and unloading, and stacking and collecting. The magnetic support component is made entirely of non-magnetic material, which does not interfere with the distribution of the magnetizing magnetic field, ensuring magnetization saturation and consistency. Simultaneously, the through-slot, limiting plate, and guide slot with a width smaller than the magnet to be magnetized form an upper and lower limiting structure, effectively preventing the magnet from slipping out. The shoulders at both ends of the guide groove limit the stroke of the pusher, preventing it from slipping out, getting stuck, or being lost, thus ensuring the stable operation of the pusher structure. Laterally sliding sealing components allow for switching between lateral sealing and limiting during magnetization and alignment during unloading. Extended protrusions at both ends further enhance sliding stability, effectively preventing lateral magnet displacement and improving magnetization accuracy and unloading smoothness. The buffer assembly continuously feeds material via a conveyor belt and utilizes a rotating lifting and avoidance-type material-pushing structure to precisely push the magnetic carrier to the temporary storage plate for standby without interfering with the conveying operation. This ensures the orderly supply of materials to the magnetization station; the integrated three-section magnetization track, combined with the propulsion component, enables smooth feeding of the load-bearing components, fixed-point magnetization, and temporary storage after magnetization, with tight process connections and high positioning accuracy; the pushing component precisely positions the load-bearing components through the abutment block, and uses the cooperation of two components to complete the sealing, clearance, and magnet ejection unloading, and the abutment block adopts a low-height limiting protrusion structure to reserve sufficient clamping space for the robot arm, facilitating automated material handling; the material tray unloading component adopts a double belt interval conveyor structure, using the central hollow section to provide passage space for the pushing mechanism, and cooperates with the four-section dropping component. The feeding structure, which releases material to each individual piece, can accurately and stably feed empty trays one by one, preventing multiple trays from stacking and jamming. At the same time, the tray-retrieving component is equipped with a dual-shaft backstop component, which uses bidirectional swing and unidirectional self-locking principle to achieve automatic stacking function for full trays to pass upwards and prevent them from falling downwards, ensuring stable and reliable stacking. In addition, a soft push pad is set at the front end of the pusher to buffer the push impact, prevent workpiece collision and deformation, and reduce equipment noise. The push drive component is equipped with a floating buffer negative pressure suction cup with pressure relief microchannel, which actively breaks the vacuum before resetting, preventing the suction cup from pulling the tray and causing bumps and displacement.

Detailed Implementation

[0036] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0037] Please see Figures 1 to 14As shown, the present invention provides a fully automatic magnetization device for neodymium iron boron magnets, comprising a magnetic carrier 1, a feeding mechanism 2, a buffer assembly 3, a magnetization assembly 4, a pushing assembly 5, and a tray unloading assembly 6. The magnetic carrier 1 houses a magnet to be magnetized 7. The magnetic carrier 1 is conveyed to the buffer assembly 3 for temporary storage via the feeding mechanism 2. An external robot moves the magnetic carrier 1 on the buffer assembly 3 to the magnetization assembly 4 for magnetization. After magnetization, the external robot moves the magnetic carrier 1 carrying the magnetized magnet to the pushing assembly 5. The pushing assembly 5 pushes the magnetized magnet inside the magnetic carrier 1 outward for unloading. The external robot then transfers the unloaded magnetized magnet to the tray unloading assembly 6 to complete the stacking. The magnetic support component 1 includes a body part 8, a limiting plate 9, and a pushing component 11. The body part 8 has a through groove 12 along its length, and one end of the body part 8 has a first opening 13 that communicates with the through groove 12. The limiting plate 9 is assembled on the body part 8, and the limiting plate 9 has a guide groove 14 along its length, which communicates vertically with the through groove 12. The pushing component 11 includes a first pushing block 15 and a second pushing block 16 perpendicularly disposed on the first pushing block 15. 5. The sliding housing is located at the end of the through groove 12 away from the first opening 13. The magnetized part 7 is housed inside the through groove 12 and located on the side of the first push block 15 near the first opening 13. The second push block 16 protrudes from the upper surface of the limiting plate 9 via the guide groove 14. The pushing assembly 5 pushes and pulls the second push block 16, causing the first push block 15 to slide along the through groove 12, so that the first push block 15 pushes the magnetized part out of the first opening 13, thereby realizing the automatic separation and unloading of the magnetized part and the magnetic carrier 1.

[0038] Shoulders are provided at both ends of the guide groove 14. The shoulders are used to limit the sliding stroke of the second push block 16. By blocking the second push block 16, the sliding range of the first push block 15 is indirectly limited, preventing the pusher 11 from coming out of the first opening 13 along the through groove 12.

[0039] When this equipment is working, the component 7 to be magnetized is pre-placed in the through groove 12 of the main body 8 of the magnetic carrier 1. After the magnetic carrier 1 is conveyed and temporarily stored by the feeding mechanism 2 and the buffer assembly 3, it is transferred by an external robot to the magnetization assembly 4 to complete the magnetization operation. After the magnetic carrier 1 is magnetized, it is then transferred by the robot to the push assembly 5. The second push block 16 in the guide slot 14, guided by the push-pull limiting plate 9, drives the first push block 15 to slide, pushing the magnetized component in the through groove 12 out of the first opening 13 for unloading. The robot then transfers the unloaded magnetized component to the material tray unloading assembly 6 for material collection and stacking. The equipment passes through the guide slot 14 Shoulders are provided at both ends to physically limit the second pusher 16 and indirectly constrain the sliding stroke of the first pusher 15. While ensuring that the magnetized part can be pushed out smoothly and the material can be automatically separated and unloaded, the pusher 11 is effectively prevented from sliding out. The structure is simple and compact, and no additional complex limiting components are required. The pusher 11 can be stably reset and reused. It effectively eliminates problems such as material jamming, equipment downtime, parts wear and loss caused by the pusher 11 coming out. It significantly improves the overall stability and continuity of equipment operation, reduces equipment maintenance costs, and effectively improves the automation production efficiency of the entire process of magnetizing, unloading and collecting neodymium iron boron magnets.

[0040] The magnetic support component 1, the limiting plate 9, and the pushing component 11 are all made of non-magnetic materials, which will not divert the magnetizing flux or change the distribution of the magnetizing magnetic field.

[0041] The width of the guide groove 14 is smaller than the width of the magnet to be charged 7, so that the limiting plate 9 blocks the magnet to be charged 7 and prevents the magnet to be charged 7 from coming out of the guide groove 14.

[0042] The magnetic support member 1 further includes a sealing member 17. The main body 8 has second openings 18 on both sides, and these second openings 18 communicate with the through grooves 12. The sealing member 17 is slidably mounted on the main body 8. The sealing member 17 includes a first protrusion 19, a first protrusion 21 and a second protrusion 22 respectively disposed at both ends of the first protrusion 19. The first protrusion 19 has a relief groove 23 for avoiding the movement of the pushing member 11. The moving direction of the sealing member 17 is perpendicular to the sliding direction of the pushing member 11. When the first protrusion 21 protrudes from the side of the main body 8 and the second protrusion 22 is flush with the second opening 18 on one side of the main body 8, the clearance groove 23 is misaligned with the through groove 12, and the first protrusion 19 laterally blocks and limits the magnetized part 7 in the through groove 12; when the second protrusion 22 protrudes from the side of the main body 8 and the first protrusion 21 is flush with the second opening 18 on the other side of the main body 8, the clearance groove 23 is aligned with the through groove 12 so that the first pusher 15 can push the magnetized part out from the first opening 13 of the through groove 12 for unloading.

[0043] When the device is working, the component to be magnetized 7 is placed in the through groove 12 of the main body 8, and the sealing component 17 slides and adjusts its position in a direction perpendicular to the sliding direction of the pusher 11. During the magnetization stage, the sealing component 17 slides until the first protrusion 21 protrudes from the side of the main body 8 and the second protrusion 22 is flush with the second opening 18 on one side of the main body 8. At this time, the clearance groove 23 is misaligned with the through groove 12, and the first protrusion 19 forms a lateral sealing limit on the component to be magnetized 7 in the through groove 12 to prevent the component to be magnetized 7 from shifting laterally or falling out, and to ensure the stability of the magnetization position. During the unloading stage, the sealing component 17 switches to the state where the second protrusion 22 protrudes from the side of the main body 8 and the first protrusion 21 is flush with the second opening 18 on the other side of the main body 8. The clearance groove 23 is aligned with the through groove 12, the lateral obstruction is released, and the first pusher 15 of the pusher 11 allows the magnetized component to be pushed out from the first opening 13 for unloading. The sealing component 17 adopts a single-component sliding switching sealing / It avoids two working conditions, has a simple structure, and can simultaneously achieve lateral locking and unloading by relying solely on lateral sliding. The positioning is reliable and the switching action is simple. It can prevent the lateral movement of the part to be magnetized 7, improve the consistency of magnetization and the smoothness of unloading, and adapt to the continuous operation requirements of automated magnetization and unloading of neodymium iron boron magnets.

[0044] The first protrusion 21 and the second protrusion 22 are respectively vertically arranged at both ends of the first protrusion 19. The length of the protrusion is greater than the thickness of the first protrusion 19. The first protrusion 21 and the second protrusion 22 have a longer contact length with the side of the body. The sealing part 17 is less likely to deviate or get stuck when it slides laterally, and the positioning stability is better.

[0045] The buffer assembly 3 includes a first driving member 24, a conveyor belt 25 connected to the output end of the first driving member 24, and a material feeding assembly 26 disposed on the side of the conveyor belt 25. The conveyor belt 25 is arranged parallel to the magnetizing assembly 4. A temporary storage plate 27 is provided on the side of the conveyor belt 25 near the magnetizing assembly 4. The temporary storage plate 27 is used to receive the magnetic carrier 1 conveyed to the position by the conveyor belt 25. The material feeding assembly 26 is used to push the magnetic carrier 1 on the conveyor belt 25 to the temporary storage plate 27 for temporary storage and positioning, so that an external robot arm can grasp and transfer it to the magnetizing assembly 4.

[0046] The feeding assembly 26 includes a first sliding guide rail 28, a first support frame 29 reciprocatingly sliding on the first sliding guide rail 28, a rotary motor 31 fixed on the first support frame 29, a feeding plate 32 connected to the output end of the rotary motor 31, and a second driving member 33 for driving the first support frame 29 to slide. The feeding plate 32 is suspended above the conveyor belt 25 and includes a first plate 34 and a second plate 35 disposed on the first plate 34. The second plate 35 is used to abut against the magnetic bearing. On the side of component 1; the second driving component 33 drives the first support frame 29 to slide along the first sliding guide rail 28, causing the second plate 35 to push the magnetic carrier 1 to move laterally to the temporary storage plate 27 for positioning; after the magnetic carrier 1 is pushed into place, the rotary motor 31 drives the feeding plate 32 to rotate and lift, separating it from the conveying surface of the conveyor belt 25, and the second driving component 33 drives the first support frame 29 to return and slide to reset. Then the rotary motor 31 drives the feeding plate 32 to rotate and press down to reset to the feeding station, waiting for the next feeding operation.

[0047] During operation, the first driving component 24 drives the conveyor belt 25 to transport the magnetic carrier 1 carrying the magnetic component 7 to be magnetized. After the magnetic carrier 1 is transported to the corresponding position, the second driving component 33 drives the first support frame 29 to slide along the first sliding guide rail 28, so that the second plate 35 on the feeding plate 32 abuts against the side of the magnetic carrier 1, pushing the magnetic carrier 1 laterally onto the temporary storage plate 27 to complete temporary storage and positioning, so that the external robot arm can grasp and transfer it to the magnetization assembly 4. After the magnetic carrier 1 is pushed into place, the rotary motor 31 drives the feeding plate 32 to rotate. The material is lifted to detach from the conveyor belt 25, and then the second drive component 33 drives the first support frame 29 to return to its original position by sliding and resetting. After that, the rotary motor 31 drives the material feeding plate 32 to rotate and press down to return to the feeding position to wait for the next operation. The feeding component 26 adopts a structure of sliding push combined with rotation lifting to avoid obstacles. The push positioning is reliable. When returning, the material feeding plate 32 is lifted and will not interfere with the continuous feeding of the conveyor belt 25. It can stably complete the transfer and temporary storage of the magnetic carrier 1, ensure the orderly supply of materials to the magnetization station, and facilitate the continuous automated production of the equipment.

[0048] The magnetizing component 4 includes a magnetizing part and a propulsion part. The magnetizing part includes a magnetizing base 38 and a magnetizing track 39. The magnetizing track 39 includes a first track 41, a second track 42, and a third track 43 integrally formed sequentially. The first track 41 connects to the discharge end of the buffer component 3, the second track 42 is located in the magnetizing station inside the magnetizing base 38, and the third track 43 connects to the feeding end of the pushing component 5. The propulsion part includes a third driving component 44, a pushing guide rail 45, a second support frame 46, and a pushing component 47. The second support frame 46 is slidably assembled on the pushing guide rail. The pusher 47 is fixed on the second support frame 46 and is located at the end of the first track 41 away from the second track 42. The third drive 44 drives the second support frame 46 to slide back and forth along the magnetic pusher rail 45, which drives the pusher 47 to push the magnetic carrier 1 carrying the magnetic component 7 to be magnetized on the first track 41 to the magnetization station of the second track 42 to complete the magnetization. After the magnetization is completed, the pusher 47 continues to push the magnetic carrier 1 to the third track 43 for temporary storage, waiting for the external robot to transfer it to the next process.

[0049] During operation, the magnetic carrier 1, delivered by the buffer component 3, is fed into the first track 41 of the magnetization track 39. The third drive component 44 drives the second support frame 46 to slide along the magnetic push guide rail 45, which in turn drives the pusher component 47 to push the magnetic carrier 1 on the first track 41 to the magnetization station inside the magnetization seat 38 located on the second track 42 to complete the magnetization. After magnetization, the pusher component 47 continues to push the magnetic carrier 1 to the third track 43 for temporary storage, waiting for the external robot arm to transfer it to the pusher component 5. The magnetization track 39 adopts an integrated structure of the first track 41, the second track 42, and the third track 43. The track docking accuracy is high and it is not easy to misalign. With the pusher component, the magnetic carrier 1 is fed smoothly, magnetized at a fixed point, and temporarily stored after magnetization. The material conveying is continuous and can stably connect the preceding and following processes, improving the automation continuity and positioning consistency of the NdFeB magnet magnetization process.

[0050] The pushing assembly 5 includes a third support frame 48, a first pushing assembly 49, a second pushing assembly 51, and an abutment block 52 disposed on the third support frame 48. When the magnetic carrier 1 carrying the magnetized component is transferred to the work position of the third support frame 48, the first pushing assembly 49 is directly opposite one end of the top pushing member 11 of the magnetic carrier 1, and the abutment block 52 is abutted against and limited at the first opening 13 end of the magnetic carrier 1, thereby fixing and positioning the magnetic carrier 1. The second pushing assembly 51 is located on the side of the magnetic carrier 1 and is used to drive the sealing member 17 to slide laterally, so that the clearance groove 23 of the sealing member 17 is aligned and connected with the through groove 12 of the body part 8. After the alignment is completed, the first pushing assembly 49 pushes and pulls the second pushing block 16 of the top pushing member 11, causing the first pushing block 15 to slide along the through groove 12, pushing the magnetized component inside the through groove 12 out through the first opening 13, thus completing the automatic unloading operation of the magnetized component.

[0051] The abutment block 52 includes a main body 53, a first limiting protrusion 54 and a second limiting protrusion 55 disposed on the main body 53. The first limiting protrusion 54 and the second limiting protrusion 55 are arranged in parallel and spaced apart, and together they form a feeding groove 56 that is aligned and connected with the through groove 12. The height of the first limiting protrusion 54 and the second limiting protrusion 55 is less than the height of the magnetized part, so that when the magnetized part is pushed out of the feeding groove 56, the upper surface of the magnetized part is higher than the upper surface of the two sets of limiting protrusions, avoiding obstruction and interference by the limiting protrusions, and reserving sufficient clamping space for the external robot arm.

[0052] The magnetic carrier 1, carrying the magnetized component, is transferred to the third support frame 48. The abutment block 52 abuts against the first opening 13 end of the magnetic carrier 1 for positioning. The first pushing component 49 is aligned with one end of the pusher 11. The second pushing component 51 drives the sealing component 17 to slide laterally, so that the clearance groove 23 of the sealing component 17 is aligned and connected with the through groove 12 of the main body 8. Then, the first pushing component 49 pushes and pulls the second push block 16 of the pusher 11, causing the first push block 15 to slide along the through groove 12, pushing the magnetized component out through the first opening 13 for unloading. The abutment block 52... 2. The first limiting protrusion 54 and the second limiting protrusion 55, which are set in parallel intervals, form a feeding groove 56 that is aligned and connected with the through groove 12. The height of the two sets of limiting protrusions is less than the height of the magnetized part. After the magnetized part is pushed out of the feeding groove 56, its upper end face is higher than the upper end face of the limiting protrusion, so it will not block or interfere with the external robot arm. A reliable clamping space is reserved. The entire set of pushing components 5 can complete the positioning of the bearing component, the relocation of the sealing component 17, and the unloading action of the magnet in sequence. The process is coordinated in an orderly manner, the unloading is stable and it is easy for the robot arm to pick up the material, ensuring smooth connection of automated operation.

[0053] The material tray unloading assembly 6 includes a material tray track 57, a tray dropping assembly 58, and a tray picking assembly 59. The tray dropping assembly 58 and the tray picking assembly 59 are respectively located at both ends of the material tray track 57, and a gap 61 is formed between the tray dropping assembly 58 and the tray picking assembly 59. The tray dropping assembly 58 is used to drop empty material trays onto the material tray track 57. The empty material trays are transported to the gap 61 position via the material tray track 57 to receive the magnetized parts transferred by the external robot. The filled full material trays are transported to the tray picking assembly 59 station via the material tray track 57, and the tray picking assembly 59 completes the automatic stacking and receiving operation of the full material trays.

[0054] The material tray track 57 includes a third guide rail 62, a first conveyor belt 63 and a second conveyor belt 64 arranged parallel to the third guide rail 62. The first conveyor belt 63 and the second conveyor belt 64 are symmetrically spaced on the left and right, and a hollow part 65 is formed between the first conveyor belt 63 and the second conveyor belt 64. The material tray is supported on the first conveyor belt 63 and the second conveyor belt 64 on both sides respectively, and the material tray is transferred by the synchronous operation of the first conveyor belt 63 and the second conveyor belt 64.

[0055] During operation, the tray dropping assembly 58 lowers empty trays onto the first conveyor belt 63 and the second conveyor belt 64 of the tray track 57. The empty trays are then moved to the interval section 61 by the two synchronously operating and symmetrically spaced conveyor belts, where they receive magnetized parts transferred by an external robot. The filled trays are then conveyed by the conveyor belts to the tray retrieval assembly 59 for automatic stacking and collection. A hollow section 65 is formed between the first conveyor belt 63 and the second conveyor belt 64, which provides passage space for the pushing structure of the tray dropping and retrieval station below. The trays are supported and conveyed by belts on both sides, resulting in smooth transport and a simple structure. This allows for stable and continuous automated operation of empty tray supply, material reception, and full tray stacking and collection.

[0056] The tray-dropping assembly 58 includes a fourth support frame 66, four sets of first baffles 67 disposed on the fourth support frame 66, four sets of clamping members 68, and a first push-drive member 71. A first discharge hole 72 is opened in the center of the fourth support frame 66, and the first discharge hole 72 is opposite to the hollowed-out portion 65. The first push-drive member 71 is located below the hollowed-out portion 65. The four sets of first baffles 67 are arranged around the first discharge hole 72 and enclose it to form a first receiving chamber 73 for stacking and storing empty trays. The first baffles 67 have first clearance holes 74 communicating with the first receiving chamber 73. The four sets of clamping members 68 are respectively disposed on the sides of the four sets of first baffles 67. The holding member 68 can pass through the first clearance hole 74 of the corresponding first baffle 67 and extend into the first receiving chamber 73 to clamp and position the empty material tray from all sides. When the empty material tray is unloaded, the first push drive member 71 moves upward and approaches the bottom of the stacked empty material trays, leaving a thickness gap for the falling of a single set of empty material trays. Then, the four sets of clamping members 68 retract and exit the first receiving chamber 73, the bottom single set of empty material trays falls and is supported by the first push drive member 71, and the remaining stacked empty material trays are clamped and positioned again by the clamping members 68. Finally, the first push drive member 71 moves downward, driving the single set of empty material trays to fall through the first dropping hole 72 onto the tray track 57, completing the single empty material tray unloading.

[0057] Multiple empty trays are stacked and stored within a first receiving chamber 73 formed by four sets of first baffles 67. Clamping members 68 pass through first clearance holes 74 to laterally clamp and position the stacked empty trays. During the empty tray unloading operation, the first push drive 71 moves upwards towards the bottom of the stacked empty trays, leaving a thickness allowance for the single empty tray's fall. Then, the four clamping members 68 retract and exit the first receiving chamber 73, with only the bottommost empty tray falling onto the first push drive 71. The remaining stacked empty trays are then clamped... The holder 68 extends and re-clamps and fixes the material, and then the first push drive 71 moves downward, driving the single empty material tray through the first drop hole 72 and onto the tray track 57 to complete a single material feeding. The tray feeding assembly 58 adopts a four-sided clamping method combined with the push drive to lift and release, which can achieve the separation and dropping of only one empty material tray at a time, effectively preventing multiple material trays from sticking together and falling down together. The tray feeding action is reliable and the separation is accurate, which can stably and continuously supply empty material trays to the tray track 57, ensuring the continuous and automated operation of subsequent material filling processes.

[0058] The tray-retrieving assembly 59 includes a fifth support frame 75, four sets of second baffles 76 disposed on the fifth support frame 75, four sets of backstop assemblies 77, and a second push-drive component 78. A second discharge hole 79 is provided in the center of the fifth support frame 75, and the second discharge hole 79 is vertically aligned with the hollowed-out portion 65. The second push-drive component 78 is located below the hollowed-out portion 65. The four sets of second baffles 76 are arranged around the second discharge hole 79 to form a second accommodating chamber 81 for stacking and storing full trays. Each second baffle 76 has a second clearance hole 82 communicating with the second accommodating chamber 81. The four sets of backstop assemblies 77 are respectively disposed on the outer sides of the four sets of second baffles 76. It can extend into the second receiving chamber 81 through the corresponding second clearance hole 82 to support the stacked full material trays; when the full material trays are stacked, a single set of full material trays carrying the magnetized parts is moved to the position above the tray taking assembly 59 along the tray track 57, and the second push drive 78 pushes the full material tray upward, so that the full material tray moves upward into the second receiving chamber 81; during the upward movement of the full material tray, it presses against the backstop assembly 77, triggering the backstop assembly 77 to swing inward to allow the full material tray to pass smoothly upward; after the full material tray completely passes the backstop assembly 77, the backstop assembly 77 resets and extends, tilting against and supporting the full material tray to achieve the stacking limit of the full material trays; then the second push drive 78 moves downward to reset, waiting for the next set of full material trays to be pushed and stacked.

[0059] The filled tray is moved along the tray track 57 to the station above the tray taking assembly 59. The second push drive 78 pushes the tray upward, causing it to move upward through the second drop hole 79 into the second receiving chamber 81 formed by the four sets of second baffles 76. During the upward movement of the tray, the backstop component 77 is squeezed and forced to swing inward to allow the tray to pass smoothly. After the tray has completely passed the backstop component 77, the backstop component 77 returns to its original position, extends and tilts to support the tray, completing the stacking limit of the tray. Then the second push drive 78 moves downward to return to its original position for the next stacking operation. The tray taking assembly 59 relies on the one-way passage and reverse support self-locking characteristics of the backstop component 77 to only allow the trays to stack upward and prevent the trays from falling back. The structure is simple and reliable, and it can realize the automatic and orderly stacking of trays, which is suitable for the needs of automated continuous material receiving.

[0060] The backstop assembly 77 includes a fixed block 83, a first rotating block 84, a connecting block 85, a connecting rod 86, a first rotating shaft 87, and a second rotating shaft 88. The fixed block 83 includes a first block 89 and a second block 91 perpendicularly disposed on the first block 89. The first rotating block 84 has a first groove 92 and a second groove 93 respectively on both sides. The connecting block 85 includes an integrally formed first main body 94 and a second main body 95. The first main body 94 has a receiving hole 96, and the second main body 95 has a through hole 97. 7. The opening directions of the receiving hole 96 and the through hole 97 are perpendicular to each other; one end of the connecting rod 86 is fixed to the first block 89, and the other end is fixedly connected to the receiving hole 96 of the first main body 94, so that the connecting block 85 is fixed as a whole and has no relative rotation; the two side walls of the first groove 92 are respectively provided with a first rotating hole 98 and a second rotating hole 99, and the first rotating shaft 87 passes through the first rotating hole 98, the through hole 97 and the second rotating hole 99 in sequence, so that the first rotating block 84 can swing relative to the connecting block 85 around the first rotating shaft 87; The second block 91 has a third rotating hole 101, and the two side walls of the second groove 93 have a fourth rotating hole 102 and a fifth rotating hole 103 respectively. The second rotating shaft 88 passes through the fourth rotating hole 102, the third rotating hole 101 and the fifth rotating hole 103 in sequence, so that the first rotating block 84 can swing relative to the fixed block 83 around the second rotating shaft 88. The first rotating shaft 87 and the second rotating shaft 88 are arranged parallel to each other, and the distance from the first rotating shaft 87 to the first block 89 is less than the distance from the second rotating shaft 88 to the first block 89. The first rotating block 84 is normally kept in an outward tilted supporting posture. When the second pushing drive 78 pushes the full material tray upward, the side wall of the full material tray presses against the first rotating block 84, driving the first rotating block 84 to swing inward around the first rotating shaft 87 and the second rotating shaft 88 to avoid it, allowing the full material tray to move upward and enter the second accommodating chamber 81. After the full material tray moves upward and loses contact, the first rotating block 84 automatically returns to the tilted posture, stably supporting the current full material tray and all the full material trays stacked above it, realizing the stacking function of the full material tray moving upward and self-locking support downward.

[0061] During operation, the backstop component 77 relies on the first rotating shaft 87 and the second rotating shaft 88, which are parallel to each other and at different distances from the first block 89, to constrain the first rotating block 84. Under normal conditions, the first rotating block 84 maintains an outward tilted supporting posture. When the second push drive component 78 pushes the full material tray upward, the side wall of the full material tray presses against the first rotating block 84, driving the first rotating block 84 to swing inward synchronously around the first rotating shaft 87 and the second rotating shaft 88 to avoid obstruction, allowing the full material tray to smoothly move upward into the second receiving chamber 81. After the full material tray is released from contact, the first rotating block 84 automatically returns to the tilted posture, stably supporting the current full material tray and all the full material trays stacked above it. This achieves the unidirectional stacking function of the full material tray, which can only pass upward and is self-locking downward. The dual-shaft linkage structure is stable and swings smoothly, which can reliably achieve unidirectional stacking of full material trays to prevent them from falling, ensuring that the tray taking component 59 can continuously and stably complete the automatic stacking operation of full material trays.

[0062] The opening width of the hollow part 65 is greater than the diameter of the first material dropping hole 72 and the second material dropping hole 79, so that the pushing stroke of the push drive and the falling stroke of the material tray are completely unobstructed, ensuring that the material dropping of the empty material tray and the pushing and stacking of the full material tray are smooth and without jamming.

[0063] The front end of the pusher 47 is provided with a soft push pad. The soft push pad contacts the end of the magnetic support 1 and pushes against it, so as to avoid deformation of the support and collision of the magnetic component 7 to be charged caused by rigid push. At the same time, it buffers the push impact force and reduces the operating noise of the equipment.

[0064] The push drive component includes a push cylinder 104, a push plate 105 disposed at the output end of the push cylinder 104, and a suction cup 106 disposed on the push plate 105. The suction cup 106 is a floating buffer negative pressure suction cup 106, which includes a plate body and a flexible lip. The plate body is fixed to the bottom surface of the push plate 105, and an adsorption cavity is provided inside the plate body. The flexible lip is arranged around the lower port of the adsorption cavity. The negative pressure air passage is connected to the adsorption cavity, and a pressure relief microchannel is provided in parallel with the negative pressure air passage. When the negative pressure air source is closed, the pressure relief microchannel introduces normal pressure air into the adsorption cavity to break the vacuum. Before the push cylinder 104 moves downward, the vacuum adsorption force is broken to prevent the suction cup 106 from pulling the material plate and causing bumps and displacement.

[0065] The suction cup 106 has a simple structure and is easy to assemble. It relies on the pressure relief microchannel to introduce normal pressure air into the adsorption chamber in advance to break the vacuum after the negative pressure air source is closed. Before the push cylinder 104 moves down, the adsorption force is released first to avoid the suction cup 106 directly tearing the material tray and causing bumps and displacement. This ensures that the lifting and releasing action of the material tray in the tray dropping and tray picking process is stable and controllable.

[0066] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0067] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
