Description

Technical Field

[0001] This invention relates to the technical field of permanent magnet levitation rail transit, and in particular to a magnetized permanent magnet assembly equipment and assembly method. Background Technology

[0002] With the development of the rare earth industry, sintered NdFeB magnets have been creatively applied to the field of magnetic levitation rail transit. In order to improve the buoyancy of permanent magnet levitation, permanent magnets are combined in a Hellbeck array inside the permanent magnet levitation track unit. After the permanent magnets are combined, the magnetism on one side is strengthened and the magnetism on the other side is weakened accordingly, thereby improving the utilization rate of magnetic energy.

[0003] Magnetized permanent magnets have a strong attraction to ferromagnetic materials, making it impossible to assemble them by hand. Furthermore, due to the magnetic force, like poles can easily repel, flip, or unlike poles can easily attract each other, which can easily cause personal safety accidents.

[0004] The patent, with publication number CN209292800U, is entitled "An Assembly Fixture for a Permanent Magnet Levitation Track Unit and Its Usage Method." It includes a fixed bracket, a sliding assembly, a large positioning block, and a small positioning block. All components are non-magnetic. The fixed bracket comprises a base plate, a top plate, a baffle, and a sliding rod. The base plate has connecting grooves on its left and right sides. The lower end of the connecting rod seat at the bottom of the levitation track unit passes through the connecting grooves and is fixedly connected to the base plate via a pre-set through hole at the lower end of the connecting rod seat using bolts. The base plate has a top plate and a baffle on its left and right sides, respectively. The sliding assembly includes a small pressure plate, a large pressure plate, a slider, and a top rod. The small pressure plate, large pressure plate, and slider are slidably connected to the sliding rod on both sides and can move back and forth.

[0005] However, this patent uses a manual assembly method to assemble the permanent magnet levitation track units, and the next set of arrays can only be assembled after one set of arrays has been assembled. Although it can achieve the purpose of assembly, the assembly efficiency is low and it is not suitable for the large-scale assembly and manufacturing of permanent magnet levitation track units. To achieve the large-scale production and manufacturing of permanent magnet levitation track units, it is necessary to rely on automated equipment. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetized permanent magnet assembly equipment and assembly method to replace the defects of manual assembly in the original technology, realize automated assembly, have high work efficiency, and be more reliable and stable than manual assembly.

[0007] To achieve the above objectives, the present invention provides a magnetized permanent magnet assembly device, comprising a permanent magnet levitation track unit, a top plate, several rows of positioning bars, and a propulsion mechanism. The permanent magnet levitation track unit, top plate, positioning bars, and propulsion mechanism are all non-magnetic components. The permanent magnet levitation track unit has a top plate at one end along its length, and the top plate is capable of moving left and right along the width direction of the permanent magnet levitation track unit. The top plate has at least one groove and a stop. Multiple rows of positioning bars are arranged within the permanent magnet levitation track unit along its length. A portion of the positioning bars corresponding to the grooves can pass through the grooves, forming a channel within the permanent magnet levitation track unit. Another portion of the positioning bars are confined within the permanent magnet levitation track unit by the stop. A feeding area is provided at the other end of the permanent magnet levitation track unit along its length, and a permanent magnet is placed within the feeding area. The propulsion mechanism pushes the permanent magnet into the channel.

[0008] This technical solution replaces traditional manual operation, which requires numerous positioning blocks and individual pushing for the assembly of each permanent magnet. Instead, this solution utilizes a coordinated setup of a track unit, top plate, multiple positioning strips, and a propulsion mechanism. The top plate features grooves and baffles, enabling simultaneous pushing of the permanent magnet and pushing of the positioning strips during assembly. This simplifies the process and allows for positioning of the permanent magnet during the pushing process, preventing deviation. The baffles on the top plate also block positioning strips in other columns, achieving a synergistic effect. The width and height of the grooves on the top plate can be set slightly larger than the width and height of the permanent magnets, allowing for the extrusion of one or more columns of positioning strips while simultaneously blocking the remaining columns of positioning strips and permanent magnets.

[0009] Preferably, the propulsion mechanism includes a rolling assembly, which includes a motor, a reducer connected to the motor, a rolling shaft connected to the reducer, and a rolling wheel mounted on the rolling shaft. When the rolling wheel rolls, it drives the permanent magnet to move into the channel. The rolling shaft is connected to the reducer through a first universal coupling.

[0010] In conjunction with the above technical solutions, this technical solution includes a rolling shaft and a rolling wheel connected to the rolling shaft on the upper side of the feeding area to increase friction. When the rolling wheel rolls, the friction between it and the permanent magnet drives the permanent magnet to move into the channel of the track unit. The rolling wheel propels the permanent magnet with a small pushing force. This is to facilitate adjustment of the permanent magnet's pushing stroke and prevent excessive pushing force from pushing the positioning strip or the already installed permanent magnet out of the track unit, thus damaging the permanent magnet. Furthermore, considering the coating on the surface of the permanent magnet, a lighter pushing force is required, ensuring... The automatic assembly of permanent magnets improves work efficiency and minimizes damage to the permanent magnets. The rolling wheel in this technical solution can be made of rubber. Combined with the coupling, the vertical position of the rolling wheel can be adjusted, thereby adjusting the distance between it and the permanent magnet to increase or decrease the reverse force on the permanent magnet, generating greater or less friction to adapt to different working conditions and the pushing of permanent magnets of different thicknesses, without damaging the protective coating on the surface of the magnetized permanent magnet. This achieves a technical effect of 1+1>2 in the adjustment of the rolling wheel.

[0011] Furthermore, the feeding area is provided with a feeding platform, the feeding platform is provided with a rolling groove, the permanent magnet is located on the rolling groove, the propulsion mechanism also includes an auxiliary rolling shaft and an auxiliary rolling wheel installed on the auxiliary rolling shaft, the auxiliary rolling wheel is attached to the rolling groove, the auxiliary rolling wheel rolls simultaneously when the permanent magnet rolls, and the rolling shaft is connected to the feeding platform through a second universal coupling.

[0012] Combining the above technical solutions, an auxiliary rolling wheel is set under the feeding platform. When the rolling wheel pushes the permanent magnet, it simultaneously drives the auxiliary rolling wheel to roll, which can reduce the friction between the bottom surface of the feeding platform and the permanent magnet, further protecting the coating layer on the surface of the permanent magnet. Furthermore, through the connection of the second universal coupling, the distance between the auxiliary rolling wheel and the permanent magnet can be adjusted to better reduce the friction when the permanent magnet is pushed, thus protecting the coating layer on the surface of the permanent magnet.

[0013] Furthermore, the propulsion mechanism also includes a clamping assembly, which includes a hydraulic cylinder and a clamping block connected to the hydraulic cylinder. The clamping block pushes the permanent magnets so that the permanent magnets located in the same row are brought closer to each other.

[0014] Based on the above technical solutions, after a row of permanent magnets is assembled, the repulsive force between the permanent magnets will cause gaps between adjacent permanent magnets, affecting the assembly effect of the track unit. Furthermore, pushing the entire row of permanent magnets requires a large pushing force. At this point, the clamping block is needed to assist in pushing the magnets forward. By utilizing the fixed stroke of the hydraulic cylinder, the entire row of permanent magnets is pushed forward in a unified manner, bringing the permanent magnets closer together and improving the assembly effect of the track unit. This replaces the traditional method of pushing and precisely bringing adjacent permanent magnets closer together, which requires pins to position the permanent magnets. In this technical solution, the clamping block is pushed forward in a unified manner, which is more efficient, prevents horizontal displacement of the permanent magnets, and does not damage the permanent magnets.

[0015] Furthermore, the assembly equipment also includes a clamping mechanism, which includes a clamping plate and a plurality of clamping blocks connected to the clamping plate. The width of the clamping blocks is slightly smaller than the width of the permanent magnet, and the clamping blocks clamp the permanent magnet to prevent the permanent magnet from moving upward.

[0016] In conjunction with the above technical solution, since the permanent magnets are arranged in a Hellbeck array on the track unit, and considering the influence of processing accuracy, some magnets are uneven or tilted to one side, which affects the overall flatness of the track unit. After all the permanent magnets are installed in the track unit, the permanent magnets are collectively pressed to prevent them from bulging, misaligning, or tilting. Combined with the pins used to fix the permanent magnets, the stability and surface flatness of the permanent magnets during assembly are further improved. In this technical solution, the number of pressing blocks is the same as the number of permanent magnets, and the vertical center of the pressing blocks initially coincides with the vertical center line of the permanent magnets, but their width is set to be slightly smaller than the width of the permanent magnets, so as to achieve effective pressing of the permanent magnets.

[0017] Preferably, the clamping mechanism further includes a connecting piece and a driving assembly for driving the clamping plate to slide vertically. The connecting piece is provided with a connecting groove, and the clamping plate and the clamping block are connected through the connecting groove. A filling block is provided between the two clamping blocks, and the filling block is connected to the clamping plate. The length of the filling block is less than the length of the clamping block.

[0018] In conjunction with the above technical solutions, when pressing the upper surface of the permanent magnet, it is necessary to adapt to the pressing of permanent magnets of different thicknesses and to better adjust the pressing force of the permanent magnets. A connecting piece with a connecting groove is set. The position of the pressing block relative to the connecting groove is adjusted according to actual needs, so that the pressing block can make slight adjustments in the vertical direction relative to the pressing plate. This makes it easy to adjust the pressing and loosening of one or several rows of permanent magnets when the pressing plate is stationary. It also achieves the alignment of the fixing holes of the permanent magnets and uses pins to position the permanent magnets, further improving the assembly effect and stability of the track unit.

[0019] Preferably, the width of the positioning strip is slightly smaller than the width of the permanent magnet, and the length of the positioning strip is an integer multiple of the length of the permanent magnet.

[0020] Based on the above technical solutions, the positioning strip is made of non-magnetic material, preferably nylon. Its width is slightly smaller than that of the permanent magnet, leaving a certain gap to facilitate the insertion of the permanent magnet into the track unit during assembly. The length of the positioning strip is an integer multiple of the permanent magnet. This design can achieve the filling and replacement of empty spaces of the magnetized permanent magnet by combining positioning strips of different lengths. When assembling one or several columns of permanent magnets, the remaining columns of permanent magnets are replaced by positioning strips.

[0021] An assembly method for a magnetized permanent magnet assembly device includes the following steps:

[0022] (1) Place multiple rows of positioning strips parallel to the permanent magnet levitation track unit inside the permanent magnet levitation track unit.

[0023] (2) Adjust the left and right position of the top plate so that the positioning strip located in the outermost column can pass through the groove of the top plate.

[0024] (3) Place permanent magnets in the feeding area of ​​the permanent magnet levitation track unit, corresponding to the columns of the grooves.

[0025] (4) The rolling component pushes the permanent magnet into the permanent magnet levitation track unit.

[0026] (5) After a row of permanent magnets is placed into the permanent magnet levitation track unit, the clamping component pushes the permanent magnets to completely push them into the permanent magnet levitation track unit.

[0027] (6) readjust the left and right positions of the top plate so that the positioning strips of the adjacent columns can pass through the grooves of the top plate. Repeat steps (3)-(5) until the last column of permanent magnets is assembled.

[0028] (7) Adjust the vertical position of the clamping mechanism, clamp the assembled permanent magnet with the clamping block, and fix the permanent magnet with the shaft pin.

[0029] This technical solution replaces traditional manual assembly, realizing automated operation of permanent magnet assembly. By utilizing the combined action of positioning bars, top plates, rolling components, clamping components, pressing mechanisms, and axle pins, it achieves uniformity in the assembly of permanent magnets in a row. The coordinated action of the top plate, track unit, clamping plate, rolling wheels, and clamping blocks restricts the movement of the magnetized permanent magnets in the up-down, forward-backward, and left-right directions, ensuring that the magnetized permanent magnets move to the set position according to the set trajectory and speed. This significantly reduces labor intensity, improves the reliability and safety factor of magnetized permanent magnet assembly, and eliminates the need for the complex placement and removal of positioning bars in traditional manual assembly. The assembly method is simple and further improves work efficiency.

[0030] Preferably, step (3) includes the following steps:

[0031] (3-1) Apply glue to the bottom of the permanent magnet.

[0032] (3-2) Place permanent magnets in the feeding area of ​​the permanent magnet levitation track unit, corresponding to the columns of the grooves.

[0033] (3-3) Place the remaining columns into positioning blocks, with the height of the positioning blocks lower than the height of the permanent magnets.

[0034] After assembly, the permanent magnets in this technical solution are prone to flipping, tilting, and floating due to the mutual influence between the magnets arranged in the Hellbeck array. To avoid this, adhesive is applied before pushing the permanent magnets into the permanent magnet levitation track unit. Then, the positioning strip is pushed out of the groove while the permanent magnets are pushed into the permanent magnet levitation track unit using a rolling component. Since the height of the positioning block is lower than the height of the permanent magnet, it ensures that the permanent magnets are pushed in smoothly and do not deviate from their direction during the push-out. At the same time, the adhesive helps to bond and fix the permanent magnets to the bottom of the permanent magnet levitation track unit, thereby improving assembly efficiency and the surface flatness of the permanent magnet levitation track unit, and thus improving the assembly effect.

[0035] Preferably, step (3) includes the following steps:

[0036] (3-1) Take out the positioning strip corresponding to the groove to form a permanent magnet and enter the channel.

[0037] (3-2) Apply glue inside the channel.

[0038] (3-3) Adjust the left and right positions of the top plate again to block the permanent magnet from entering the channel.

[0039] (3-4) Place permanent magnets in the feeding area of ​​the permanent magnet levitation track unit, corresponding to the column of the groove. (3-5) Place positioning blocks in the remaining columns, with the height of the positioning blocks lower than the height of the permanent magnets.

[0040] After the permanent magnets in this technical solution are assembled, they are prone to flipping, tilting, and floating due to the mutual influence between the magnets arranged in the Hellbeck array. To avoid this phenomenon, in this technical solution, the positioning strips of the corresponding columns are removed before the permanent magnets are pushed into the permanent magnet levitation track unit, and glue is applied to the channel. Compared with the method of applying glue to the permanent magnets first, this setting has a better bonding and fixing effect between the permanent magnets and the permanent magnet track unit, and the assembly effect of the permanent magnet levitation track unit is further improved.

[0041] Preferably, step (3) consists of steps (3a) and (3b).

[0042] Step (3a) includes the following steps: (3-1) Take out the positioning strip corresponding to the groove to form a permanent magnet entering the channel; (3-2) Apply glue to the channel; (3-3) Adjust the left and right position of the top plate to block the permanent magnet from entering the channel; (3-4) Place the permanent magnet corresponding to the groove in the feeding area of ​​the permanent magnet levitation track unit; (3-5) Place positioning blocks in the remaining columns, with the height of the positioning blocks lower than the height of the permanent magnet. Step (3b) includes the following steps: (3-1) Apply glue to the bottom of the permanent magnet; (3-2) Place the permanent magnet corresponding to the groove in the feeding area of ​​the permanent magnet levitation track unit; (3-3) Adjust the left and right position of the top plate to block the permanent magnet from entering the channel; (3-4) Place positioning blocks in the remaining columns, with the height of the positioning blocks lower than the height of the permanent magnet.

[0043] The assembly of the outermost column of permanent magnets is completed in step (3a), and the assembly of the permanent magnets in step (6) that are spaced an odd number of columns apart from the outermost column of permanent magnets is completed in step (3b), until the last column of permanent magnets is assembled.

[0044] After assembly, the permanent magnets in this technical solution are prone to flipping, tilting, and floating due to the mutual influence between the magnets arranged in the Hellbeck array. To avoid this, this technical solution applies adhesive to the bottom of the permanent magnets or inside the channels of the permanent magnet levitation track unit. Considering the ease of bonding between the permanent magnets and the track unit in practical applications, the adhesive can be applied to the channels first when assembling the outermost permanent magnets, and then the permanent magnets can be pushed into the track unit. When assembling the permanent magnets located on the inner side that need to be fixed downwards, the adhesive can be applied to the bottom of the permanent magnets first, and then the permanent magnets can be pushed into the track unit. Combined with other operation steps, this optimizes the workflow, simplifies the operation steps, improves the assembly effect, and increases work efficiency.

[0045] The beneficial effects of this invention are as follows: This invention replaces the manual assembly work of turning a lead screw to control forward and backward movement with the manual tooling of the original technology by using components such as a variable frequency motor and a hydraulic cylinder. This improves the efficiency of repetitive operations, simplifies the operation steps, and makes the workflow relatively simple, greatly improving work efficiency. Moreover, the hydraulic cylinder can provide greater pushing force, allowing an entire row of permanent magnets to be assembled in one go, while manual assembly can only assemble a single permanent magnet. This invention also uses an electrically controlled clamping plate to achieve up and down movement, which is more efficient than the manual screwing and repeated clamping. The computer-controlled clamping plate and the clamping block with adjustable height can precisely control the movement distance, which is more reliable and stable than manual assembly, thus improving work efficiency.
