Description

Technical Field

[0001] The present invention relates to the technical field of transfer vehicles, and in particular to a transfer vehicle and a transfer method for tile magnet green blanks. Background Art

[0002] The manufacturing process for permanent ferrite magnet tiles involves ball milling, forming, sintering, grinding, cleaning, and sorting, forming a critical chain of steps. The green tiles, after being pressed in the forming process, are fragile and prone to tipping and falling during transport and stacking. Furthermore, before entering the sintering kiln, the green tiles must be neatly stacked on 450mm x 450mm sintering plates according to a strict, fixed stacking process, placing extremely high demands on the stability and accuracy of the transport process.

[0003] Currently, the commonly used transfer solution in the industry involves manually stacking green billets in reusable wooden crates, transporting them to the sintering kiln via trailer, and finally manually stacking them again on the sintering plate on the kiln's roller table. This traditional transfer method has numerous drawbacks: Firstly, the multiple manual handling and stacking operations severely impact green billet turnover efficiency and increase labor costs; secondly, manual operations make it difficult to ensure the stability of the transfer process, leading to frequent green billet dropouts and increased product defect rates; Furthermore, this solution cannot effectively integrate with the automated production of the upper and lower kilns in the sintering process, hindering production efficiency improvements and intelligent upgrades, making it difficult to meet the efficient, stable, and automated production requirements of modern industry. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a transfer vehicle and a transfer method for tile magnetic green billets. By designing a stacking platform that can be opened and fixed by independent rotation, the transfer vehicle has the dual functions of transfer and stacking. Compared with the traditional transfer vehicle with a fixed bracket, the transfer vehicle for tile magnetic green billets does not need to transport the green billets multiple times between different platforms. The operator can directly complete the stacking of the tile magnetic green billets on the transfer vehicle for tile magnetic green billets, and then move them directly to the kiln equipment of the sintering plate process, which reduces the number of transportation times and reduces the risk of damage to the tile magnetic green billets due to transportation, while improving space utilization and the continuity of the production process.

[0010] A transfer vehicle for tile-shaped magnetic green blanks according to an embodiment of the present invention has at least the following technical effects: through the design of an independently rotating, openable, and fixed stacking platform, the transfer vehicle has the dual functions of both transfer and stacking. Compared to traditional transfer vehicles with fixed brackets, this transfer vehicle for tile-shaped magnetic green blanks does not require the green blanks to be moved multiple times between different platforms. Operators can stack the tile-shaped magnetic green blanks directly on this transfer vehicle and then move them directly to the kiln equipment for the sintering plate process. This reduces the number of transfers and the risk of damage to the tile-shaped magnetic green blanks caused by transportation, while also improving space utilization and the continuity of the production process.

[0015] The rotating assembly includes a bearing, and the bearing is installed on the crossbeam. One side of the stacking platform is fixed on the bearing and rotates around the crossbeam through the bearing.

[0016] In some specific embodiments of the present invention, the locking device includes a fixing pin, one end of which is fixed to a sleeve or a bearing, and the positioning device is a positioning hole, the other end of which is inserted into the positioning hole.

[0017] Some specific embodiments of the present invention further include a damping assembly, which uses an adjustable oil pressure damper. The adjustable oil pressure damper includes a cylinder and a piston rod. The cylinder is fixed on the frame, and the piston rod is connected to the stacking platform.

[0018] In some specific embodiments of the present invention, grooves and protrusions are provided on the surface of the stacking platform.

[0019] In some specific embodiments of the present invention, load-bearing wheels are provided at the bottom of the frame.

[0020] On the other hand, a method for transporting a tile magnetic green body of the present invention uses the aforementioned transport vehicle for transporting a tile magnetic green body, comprising the following steps:

[0021] Step 1: Rotate the stacking platforms of all layers on the transfer vehicle for the tile magnet green billet to be close to the side 1 of the vehicle frame, and fix the stacking platforms of all layers on the vehicle frame through the locking device and the positioning device;

[0022] Step 2: Open the locking device of the bottom stacking platform, rotate the bottom stacking platform to a horizontal state, and lock the locking device of the bottom stacking platform into a positioning device adapted thereto; place a sintering plate on the bottom stacking platform, and place the tile magnetic green blanks on the sintering plate to a preset height;

[0023] Step 3: As described in step 2, open the locking device of each stacking platform from bottom to top, rotate it to a horizontal state, lock it, then place the sintering plate, and place the tile magnetic green billets to a preset height until all the tile magnetic green billets are placed or the top stacking platform is full of tile magnetic green billets;

[0024] Step 4: Move the transfer vehicle of the tile magnetic green body to the sintering kiln equipment.

[0035] Example 1

[0036] On the one hand, see Figure 1 and Figure 2 As shown, a transfer vehicle for tile magnet green billets of the present invention includes a frame 101, a stacking mechanism, a rotating assembly 300 and a locking device; the stacking mechanism includes a plurality of stacking platforms 201 stacked in layers; the rotating assembly 300 is mounted on a side 1011 of the frame 101, one side of the stacking platform 201 is fixed on the rotating assembly 300, and the other side rotates around the frame 101 through the rotating assembly 300; the locking device is fixed on the rotating assembly 300 or the stacking platform 201, and is adapted to the positioning device on the frame 101.

[0037] Specifically, frame 101 includes side 1011, side 2, side 3, side 4, and a bottom surface. Side 1011 is parallel to side 3, and side 2 is parallel to side 4. Side 1011, side 2, side 3, and the other sides, in sequence, form a cylindrical structure. Side 4 is removable, meaning it can be removed or opened. Frame 101 is welded from high-strength square steel measuring 50 mm x 50 mm x 3 mm.

[0038] The stacking mechanism consists of five stacking platforms 201, each made of high-strength aluminum alloy plates and measuring 460mm x 460mm. The stacking platforms 201 are used to hold sintered plates 203, which in turn hold the tile-shaped green magnetic blanks. The sintered plates 203 measure 450mm x 450mm, and the stacking platforms 201 are no smaller than these. The vertical spacing between adjacent stacking platforms 201 is set at 150mm, ensuring smooth access for operators.

[0039] The rotating assembly 300 is mounted on a side surface 1011 of the vehicle frame 101 and rotates 45°-90° around the vehicle frame 101. The side of each stacking platform 201 adjacent to the rotating assembly 300 is connected to the rotating assembly 300 via a flat key or directly welded to the rotating assembly 300, enabling the stacking platform 201 to rotate upward 45°-90° around the vehicle frame 101. At this point, the stacking platform 201 forms an angle of 45°-90° with respect to the horizontal position.

[0040] One end of the locking device is fixed to the rotating assembly 300 or the stacking platform 201, and the other end is connected to the positioning device on the frame 101, thus locking the stacking mechanism. The positioning device is located on the frame 101 and faces the side 1011. A single stacking mechanism can have two corresponding locking devices: one for locking the stacking platform 201 when it is horizontal, and the other for locking it when it is rotated 45°-90°. The locking device and the positioning device work together to ensure that the stacking platform 201 remains stable during the stacking and transportation process, preventing it from loosening or accidentally rotating.

[0041] In this embodiment, the design of an independently rotating, openable, and fixed stacking platform 201 allows the transfer vehicle to perform both transport and stacking functions. Compared to conventional fixed-frame transfer vehicles, this vehicle for transferring tile-shaped magnetic green billets eliminates the need to repeatedly move the green billets between different platforms. Operators can stack the green billets directly on the vehicle and then move them directly to the kiln equipment for the sintering plate 203 process. This reduces the number of transfers and the risk of damage to the green billets during handling, while also improving space utilization and the continuity of the production process.

[0042] Furthermore, the transfer vehicle for the tile-shaped magnetic green pieces can also be used in conjunction with an automatic kiln loading and unloading device to achieve fully automatic loading and unloading of the sintering plate 203. Specifically, the rollers of the automatic kiln loading and unloading device enter and exit from the side of the transfer vehicle, delivering the sintering plate 203 to the kiln equipment, thus achieving efficient connection between the transfer of the tile-shaped magnetic green pieces and the sintering process.

[0043] Furthermore, the stacking mechanism includes a support frame 202, one end of which is fixed to the bottom surface of any stacking platform 201, and the other end of which is supported on the top surface of the stacking platform 201 below it. Specifically, the support frame 202 is used to support each stacking platform 201 and maintain the stability of the stacking platform 201. Specifically, the support frame 202 is fixed to the bottom surface of the stacking platform 201 at the end away from the rotating assembly 300.

[0044] To provide ample operating space for operators, one side of the transfer vehicle for the tile-shaped green magnetic blanks is designed to be open. Specifically, the vehicle frame 101 comprises three longitudinally connected side surfaces at 90° angles to one another, and a bottom surface. This not only facilitates the operator's stacking of the sintered plates 203 but also provides ample space for the automatic kiln loading and unloading equipment. During the sintering process, the rollers of the automatic kiln loading and unloading equipment can freely enter and exit the transfer vehicle, unobstructed by the frame structure of the vehicle frame 101. This allows for fully automatic loading and unloading of the sintered plates 203 into and out of the kiln, effectively increasing the level of production automation, reducing manual intervention, and improving both production efficiency and stability.

[0045] In addition, the side 1011 of the frame 101 is composed of a plurality of horizontally placed parallel beams 102; each beam 102 is rotatably connected to a rotating assembly 300; each beam 102 matches a stacking platform 201, and each stacking platform 201 rotates around its corresponding beam 102. The distance between two adjacent beams 102 is a preset distance, that is, the distance between two adjacent layers of stacking platforms 201; the beams 102 are cylindrical shafts to ensure the smooth rotation of the rotating assembly. The beams 102 are firmly fixed to the side 1011 of the frame 101 by bolts at both ends for easy disassembly. Furthermore, the rotating assembly 300 includes a sleeve that is sleeved on a beam 102 and rotates around the beam 102, with one side of the stacking platform 201 fixed to the wall of the sleeve; or the rotating assembly 300 includes a bearing, which is mounted on the beam 102, and one side of the stacking platform 201 is fixed to the bearing and rotates around the beam 102 via the bearing. Specifically, when the rotating component 300 is a sleeve, the length of the sleeve is not greater than the length of the beam 102, and it is sleeved on the beam 102 and can rotate along the axial direction of the beam 102; the outer wall of the sleeve is connected to the stacking platform 201, which is used to drive the stacking platform 201 to rotate around the axial direction of the beam 102, and a fixing component can also be connected to the connection between the sleeve and the stacking platform 201 to prevent the connection between the sleeve and the stacking platform 201 from fatigue and breakage due to frequent use; in a specific embodiment, the fixing component is a fixing plate, which is provided on the lower surface of the stacking platform 201 where the sleeve contacts the stacking platform 201. When the stacking platform 201 is in a horizontal state, the fixing plate abuts against the sleeve to bear a certain radial load. When the rotating assembly 300 is a bearing, the bearing is fixed to the mounting position reserved for the crossbeam 102. The bearing adopts a sealed design, which can effectively prevent dust or dander from entering the bearing, ensuring smooth and stable rotation. The bearing is selected as a deep groove ball bearing, which can meet the needs of frequent rotation of the stacking platform 201. At the same time, in order to enhance the load-bearing capacity, a double-row deep groove ball bearing structure is adopted to effectively withstand radial loads and a certain degree of axial loads, ensuring the stability of the rotating mechanism when stacking multi-layer tile magnetic green blanks. The stacking platform 201 is fixed to the outer ring of the bearing, allowing the stacking platform 201 to rotate axially around the crossbeam 102. Furthermore, shaft shoulders are provided at both ends of the crossbeam 102 for axial positioning of the bearing or sleeve, ensuring that the bearing or sleeve does not undergo axial transmission during rotation.

[0046] In addition, the locking device includes a fixed pin, one end of which is fixed on the sleeve or bearing, and the positioning device is a positioning hole, and the other end of the fixed pin is inserted into the positioning hole. Specifically, the fixed pin is made of high-strength stainless steel, one end of which is fixed on the sleeve or bearing along the axial direction of the crossbeam 102, and the other end is inserted into the positioning device. The positioning device is a positioning hole, which is provided on the bracket. A positioning hole 1 is provided horizontally for locking the stacking platform 201 when the stacking tile magnet green blanks are horizontally stacked; a positioning hole 2 is provided vertically for locking the stacking platform 201 to the frame 101 when the stacking platform 201 is rotated to 90°, so as to prevent the stacking platform 201 from falling, endangering the personal safety of the operator and hindering the stacking work.

[0047] The wattage green body transfer vehicle also includes a damping assembly, which utilizes an adjustable hydraulic damper. The adjustable hydraulic damper comprises a cylinder and a piston rod. The cylinder is fixed to the vehicle frame 101, and the piston rod is connected to the stacking platform 201. During rotation, the damping device controls the rotation speed to prevent the stacking platform 201 from shaking or colliding due to excessive rotation.

[0048] In order to prevent the sintering plate 203 from sliding during stacking and transportation, grooves and protrusions are set on the surface of the stacking platform 201; specifically, the surface of the stacking platform 201 is processed with anti-slip grooves with a depth of 2 mm and a spacing of 10 mm to increase the friction between the sintering plate 203 and the stacking platform 201. In addition, load-bearing wheels 103 are provided at the bottom of the frame 101; specifically, four load-bearing wheels 103 with a diameter of 200 mm and a brake device are evenly installed at the bottom of the frame 101, and the rated load of a single load-bearing wheel 103 is 500 kg, ensuring that the transfer vehicle for the tile magnetic green billets can stably carry the sintered plates 203 and green billets with a total weight of approximately 2000 kg; the load-bearing wheels 103 use high-strength rubber material to wrap the metal wheel hub, and have good wear resistance and shock absorption performance; when it is necessary to fix the transfer vehicle for the tile magnetic green billets, it is only necessary to step on the brake device to firmly fix the transfer vehicle for the tile magnetic green billets in the specified position, thereby avoiding displacement of the transfer vehicle for the tile magnetic green billets during stacking or transportation, and ensuring operational safety and stability.

[0049] On the other hand, a method for transporting a tile magnetic green body of the present invention uses the above-mentioned tile magnetic green body transport vehicle, comprising the following steps:

[0050] Step 1: Rotate all the stacking platforms 201 on the transfer vehicle for the tile magnet green blanks to be close to the side 1011 of the vehicle frame 101, and fix all the stacking platforms 201 on the vehicle frame 101 by means of a locking device and a positioning device;

[0051] Step 2: Open the locking device of the bottom stacking platform 201, rotate the bottom stacking platform 201 to a horizontal state, and lock the locking device of the bottom stacking platform 201 into a corresponding positioning device; place the sintering plate 203 on the bottom stacking platform 201, and place the tile magnetic green body on the sintering plate 203 to a preset height;

[0052] Step 3: As described in step 2, open the locking device of each stacking platform 201 from bottom to top, rotate it to a horizontal state, lock it, then place the sintering plate 203, and place the tile magnetic green billets to a preset height until all the tile magnetic green billets are placed or the top stacking platform 201 is full of tile magnetic green billets;

[0053] Step 4: Move the transfer vehicle of the tile magnetic green body to the sintering kiln equipment.

[0054] Specifically, see Figure 1 and Figure 2 As shown, five layers of stacking platforms 201 are provided on the transfer vehicle for the tile magnetic green billets. Each layer of stacking platform 201 is rotated 45°-90° around the vehicle frame 101 by the rotating assembly 300, so that the stacking platform 201 can be in a horizontal state or an inclined state. The stacking platform 201 is fixed to the vehicle frame 101 by a locking device and a positioning device. A preset distance is maintained between the stacking platforms 201 of two adjacent layers, and the preset distance is set to 150 mm. The preset height of the tile magnetic green billets is not greater than the preset distance.

[0055] Step 1: Rotate all the stacking platforms 201 80° toward the side 1011 of the frame 101, and insert the fixing pin into the matching positioning hole 1 to stably fix the stacking platform 201 on the frame 101, and maintain an 80° tilt angle to facilitate the placement of the sintered plate 203 and the placement of the tile magnet green body on the stacking platform 201.

[0056] Step 2: Open the fixing pin of the bottom stacking platform 201, rotate the bottom stacking platform 201 to a horizontal state, and insert the fixing pin of the bottom stacking platform 201 into the second positioning hole matched with it; place the sintering plate 203 on the bottom stacking platform 201, and steadily place the tile magnetic green billets on the sintering plate 203 to 100 mm, and stop placing;

[0057] Step 3: As described in step 2, the operator opens the fixed latches of each layer of the stacking platform 201 from bottom to top, and uses the rotating mechanism to stack the layer horizontally to make room for the upper sintered plate 203. Then, the sintered plate 203 is placed and the tile magnetic green billets are placed to 100 mm. The placement is stopped until all five layers of sintered plates 203 are stacked or all tile magnetic green billets are placed.

[0058] Step 4: Move the transfer vehicle of the tile magnet green body to the kiln equipment of the sintering process; cooperate with the automatic upper and lower kiln equipment to realize the fully automatic upper and lower kiln of the sintering plate 203.

[0059] The design of the layered stacking and layer-by-layer rotating stacking platform 201 effectively improves the stacking efficiency, reduces the labor intensity of the operators, and reduces the damage rate of the tile magnet green billets.

[0060] Example 2

[0061] The only difference between this embodiment and embodiment 1 is that the locking device can also be a spring snap-on locking assembly, an electromagnetic locking assembly, a wedge block locking assembly or a hydraulic latch locking assembly.

[0062] Specifically, when the locking device is a spring-loaded locking assembly, it primarily consists of a slot, a spring clip, and an operating handle. A U-shaped slot is positioned on the transfer vehicle's frame 101. The slot's depth and width precisely match the edge dimensions of the stacking platform 201, ensuring accurate positioning of the stacking platform 201 after insertion. The spring clip is mounted on one side of the slot and consists of a high-strength spring and a latch. One end of the latch is connected to the spring, while the other end is designed with a sloped structure to facilitate the stacking platform 201's automatic sliding into the slot upon insertion.

[0063] The specific method of use is as follows: When the stacking platform 201 is rotated to a horizontal position close to the vehicle frame 101, the latch automatically pops out under the action of the spring force and embeds into a groove on the edge of the stacking platform 201, achieving initial locking. To facilitate unlocking, an operating handle is provided to link with the latch, one end of which is connected to the latch via a connecting rod. When the stacking platform 201 needs to be rotated, the operator simply pulls the operating handle, causing the latch to compress and retract the spring to release the lock. The spring-loaded locking assembly is simple to operate and locks quickly. The elasticity of the spring effectively buffers vibrations during transportation, preventing the bracket from loosening.

[0064] When the locking device is an electromagnetic locking assembly, electromagnetic force is used to achieve rapid locking and unlocking. An electromagnetic chuck is mounted on the vehicle frame 101, and a magnetic metal plate is positioned at the corresponding position of the stacking platform 201. The electromagnetic chuck consists of a coil, an iron core, and a shell. When the coil is energized, the iron core generates a strong magnetic field that attracts the magnetic metal plate, causing the stacking platform 201 to fit tightly against the vehicle frame 101, completing the locking process.

[0065] The electromagnetic locking assembly is equipped with an independent electronic control system, which uses buttons or sensors to control the power supply of the electromagnetic chuck. When the stacking platform 201 rotates into position, the sensor detects a signal and automatically powers the electromagnetic chuck, instantly generating a strong suction force. To unlock, press the unlock button, disconnecting the electromagnetic chuck's power supply. The magnetic field disappears, allowing the stacking platform 201 to rotate freely. The electromagnetic locking assembly has a fast response time, is wear-free, and can be programmed for automated control, seamlessly integrating with the automated operation of the transfer vehicle.

[0066] When the locking device is a wedge block locking assembly, it consists of a wedge block, a drive screw, and an adjustment nut. An inclined wedge-shaped slot is provided on the vehicle frame 101, and a wedge-shaped hole that matches the slot is provided at a corresponding position on the edge of the stacking platform 201. The wedge block is installed in the slot, with its inclined surface aligned with the slot's inclined surface. One end of the wedge block is connected to the drive screw.

[0067] The specific usage is as follows: Once stacking platform 201 is rotated into position, the adjustment nut is rotated to drive the screw, which moves the wedge block along the wedge groove. The wedge block gradually wedges into the wedge hole of stacking platform 201, leveraging the self-locking principle of the wedge structure to securely lock the bracket to the outer frame. The wedge block locking assembly can withstand significant external forces, and the locking tightness can be fine-tuned by adjusting the nut to ensure stability under different working conditions. To unlock, rotate the adjustment nut in the opposite direction to allow the wedge block to exit the wedge hole, thereby rotating stacking platform 201.

[0068] When the locking device is a hydraulic latch locking assembly, the hydraulic latch locking assembly is based on the principle of hydraulic transmission and consists of a hydraulic cylinder, a latch, a hydraulic pump, and a control valve. The hydraulic cylinder is fixedly mounted on the vehicle frame 101, the latch is connected to the piston rod of the hydraulic cylinder, and a pin hole that matches the latch is provided on the stacking platform 201.

[0069] The specific method of use is as follows: After the stacking platform 201 is rotated into position, the control valve is operated to start the hydraulic pump. Hydraulic oil enters the hydraulic cylinder, pushing the piston rod out, driving the latch to accurately insert into the pin hole of the stacking platform 201, achieving locking. The hydraulic system has the characteristics of stable pressure and high thrust, which can ensure that the latch is firmly inserted and provide reliable locking force. To unlock, the control valve changes the flow direction of the hydraulic oil, causing the hydraulic cylinder piston rod to retract and drive the latch out of the pin hole. The hydraulic latch locking assembly adapts to the stacking requirements of sintered plates 203 of different weights and sizes by adjusting the pressure of the hydraulic pump. The hydraulic transmission is smooth, and the locking process is impact-free.

[0070] It should be noted that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the technical solution of the present invention are all included in the technical scope of the present invention. In addition, without departing from the scope of the present invention, other embodiments that can be conceived by those skilled in the art and that combine some of the constituent elements in the embodiments are also included in the scope of the present invention.
