Description
Technical Field
[0001] This application relates to the technical field of material loading platforms, and in particular to a linear motor material loading platform. Background Art
[0002] A flat linear motor generally consists of two parts: a stator and a mover. The stator is usually composed of a coil winding, which generates a magnetic field after being energized; the mover is composed of a magnetic conductive material and a permanent magnet (or a conductive plate). When an alternating current is applied to the stator coil, an electromotive force and current will be induced in the mover. According to Ampere's law, the mover will be subjected to a force perpendicular to the current direction and the magnetic field direction, thereby driving the mover to move in a straight line direction.
[0003] When the existing linear motor is used for material loading and transportation, generally, the mover of the linear motor is connected to the material loading platform, and by controlling the direction and magnitude of the current, the mover is driven to move reciprocally.
[0004] When the existing material loading platform is driven by a linear motor and moves reciprocally, it usually requires a support or a limit guide rail for limiting and supporting to ensure stability and structural strength. In this case, there is a problem of relatively large resistance, resulting in increased energy consumption. Summary of the Invention
[0005] This application provides a linear motor material loading platform, which can solve the problem that the use of a limit guide rail to limit and support the material loading platform results in relatively large resistance when the material loading platform moves.
[0006] The technical solution of this application is as follows: A linear motor material loading platform, comprising:
[0007] A heat-conducting base, the heat-conducting base being a strip-shaped member;
[0008] A linear motor assembly, disposed on the upper surface of the heat-conducting base and extending along the length direction of the heat-conducting base;
[0009] A material loading platform, disposed on the mover of the linear motor assembly. The material loading platform is an inverted U-shaped member and there is a gap between the material loading platform and the heat-conducting base. Auxiliary guiding components are respectively disposed on both sides of the lower end of the material loading platform. The auxiliary guiding components can apply a horizontal pressure perpendicular to the traveling direction of the material loading platform for guiding, and at the same time apply a pressure to the heat-conducting base, and utilize the reaction force generated by the heat-conducting base on the material loading platform to improve the supporting force of the material loading platform.
[0010] By adopting the above solution, with the use of a material-carrying platform that has a gap with the heat-conducting base, when the linear motor assembly drives the heat-conducting base to move, the resistance influence caused by the friction of the heat-conducting base is reduced. At the same time, due to the two auxiliary guiding components, they can generate pressures on the material-carrying platform that are horizontal and perpendicular to the traveling direction of the material-carrying platform, and the two pressure directions are opposite, so that the material-carrying platform will not shake in the horizontal direction.
[0011] At the same time, by using the reaction force generated by the heat-conducting base on the material-carrying platform, the load-bearing capacity of the material-carrying platform is improved, avoiding the situation where the linear motor assembly is damaged due to the excessive mass of the product.
[0012] In one embodiment of the present application, the heat-conducting base includes:
[0013] A guide rail main body, and the linear motor assembly is arranged on the upper surface of the guide rail main body;
[0014] A bottom plate, and the bottom plate is provided with two and is respectively assembled on both sides of the guide rail main body.
[0015] By adopting the above solution, by combining the guide rail main body and the bottom plate, a "convex"-shaped heat-conducting base is formed, enabling it to better fit the shape of the material-carrying platform and providing more accurate guidance.
[0016] In one embodiment of the present application, the material-carrying platform includes:
[0017] A material-carrying plate, which is horizontally arranged and located above the linear motor assembly;
[0018] Support plates, and there are two support plates, which are respectively fixedly assembled at both ends of the lower surface of the material-carrying plate. The support plates are vertically arranged and located on both sides of the guide rail main body.
[0019] By adopting the above solution, by combining the material-carrying plate and the support plates, an inverted U-shaped member is formed and buckled on the heat-conducting base, enabling the material-carrying platform to better fit the heat-conducting base.
[0020] In one embodiment of the present application, the auxiliary guiding component includes:
[0021] The first air-bearing, and the first air-bearing is horizontally arranged in two groups and is arranged on one side of the support plate close to the guide rail main body;
[0022] The second air-bearing, and the second air-bearing is vertically arranged in two groups and is arranged at the lower end of the support plate and above the bottom plate;
[0023] Both the first air-bearing and the second air-bearing are connected to the air supply device.
[0024] By adopting the above solution, by setting the first air bearing and the second air bearing, the two first air bearings can eject airflows in opposite directions. The reaction forces generated by the impact of the two opposite airflows on the heat-conducting base enable the material-carrying platform not to move erroneously in the horizontal direction.
[0025] At the same time, the second air bearing can eject an airflow towards the bottom plate, thereby generating an upward thrust on the material-carrying platform, further improving the overall support force of the device and the load capacity. In addition, by using the reaction force of the airflow, direct contact between the material-carrying platform and the heat-conducting base is avoided, thereby avoiding the generation of frictional resistance.
[0026] In one embodiment of the present application, the heat-conducting base further includes height-limiting strips. The height-limiting strips extend along the length direction of the guide rail main body and are arranged on both sides of the guide rail main body. The height-limiting strips are located above the first air bearing.
[0027] By adopting the above solution, height-limiting strips are arranged above the first air bearing, and the height-limiting strips can prevent the material-carrying platform from disengaging from the heat-conducting base, so as to improve the safety performance of the use of the material-carrying platform.
[0028] In one embodiment of the present application, air-permeable holes extending along the length direction of the height-limiting strips are opened inside the height-limiting strips. The width d1 of the air-permeable holes and the thickness d2 of the first air bearing satisfy: d1 < d2.
[0029] By adopting the above technical solution, by opening air-permeable holes inside the height-limiting strips, when the first air bearing and the second air bearing eject airflows, the airflows can pass through the air-permeable holes and reach the linear motor assembly, so that the airflows ejected by the first air bearing and the second air bearing can play a role in dissipating heat from the linear motor assembly.
[0030] In one embodiment of the present application, a water injection cavity is opened inside the guide rail main body. The water injection cavity extends along the length direction of the guide rail main body. A spiral water groove is arranged on the inner wall of the water injection cavity along the length direction of the inner wall. End caps communicating with the water groove are threadedly assembled at both ends of the guide rail main body, and a water pipe is assembled on the end caps along the tangential direction of the end caps.
[0031] By adopting the above technical solution, a water injection cavity is opened inside the guide rail main body, and water pipes are arranged at both ends of the water injection cavity. By using the water pipes arranged tangentially to the end caps, when water is introduced, the water can enter the water injection cavity through the end caps and form a vortex, improving the speed of the water flow, and further being able to accelerate the heat exchange efficiency of the water flow, and further reducing the heat of the linear motor assembly located on the heat-conducting base.
[0032] In one embodiment of the present application, limit buffer seats are provided on the upper surfaces at both ends of the guide rail main body. The two limit buffer seats are respectively located at both ends of the linear motor assembly. The limit buffer seat includes:
[0033] A fixed seat, which is fixedly assembled on the upper surface of the guide rail main body;
[0034] A hollow tube, which is disposed through the fixed seat. A piston is provided inside the hollow tube. A connecting shaft is coaxially assembled on one side of the piston. One end of the connecting shaft penetrates through one side of the hollow tube close to the material loading platform and extends to the outside of the hollow tube. A contact block is connected to one end of the connecting shaft. The other sides of the two hollow tubes are communicated through a connecting pipe, and a buffer liquid is filled inside the communicating pipe.
[0035] By adopting the above technical solution, when the material loading platform moves to the end of the stroke, the material loading platform impacts on one side at the end of the stroke, thereby pushing the contact block on this side to retract towards the hollow tube. At the same time, the contact block pushes the piston to move along the hollow tube, so that the buffer liquid inside the hollow tube is pushed through the connecting pipe to the inside of the hollow tube on the other side. The buffer liquid column can push the piston inside the hollow tube on the other side to move, and make the connecting shaft on the other side extend, so that when the material loading platform moves to the end of the stroke on the other side, the extended connecting shaft on the other side has enough buffer distance.
[0036] In one embodiment of the present application, the auxiliary guiding assembly includes:
[0037] A first magnetic plate assembly, which includes two first magnetic strips and two groups of first magnetic blocks. The two first magnetic strips are respectively assembled on both sides of the guide rail main body and extend along the length direction of the guide rail main body. The first magnetic blocks are assembled on one side of the lower end of the support plate close to the heat conducting base, and the first magnetic strip and the first magnetic block repel each other;
[0038] A second magnetic plate assembly, which includes two second magnetic strips and two groups of second magnetic blocks. The second magnetic strips are assembled on the upper surface of the bottom plate and extend along the length direction of the bottom plate. The second magnetic blocks are assembled on the lower end of the support plate and are located above the second magnetic blocks, and the second magnetic strip and the second magnetic block repel each other.
[0039] By adopting the above technical solution, by using the mutual repulsive force between the first magnetic plate assemblies, it is ensured that the material loading platform and the guide rail main body can realize the horizontal limit of the material loading platform through the repulsive forces in opposite directions without contacting each other;
[0040] At the same time, the mutual repulsion between the second magnetic plate components is utilized to ensure that the loading platform and the guide rail body can utilize the mutual repulsion between the support plate and the bottom plate without contacting each other, thereby improving the supporting capacity of the support plate and further improving the load capacity of the entire loading platform.
[0041] In one embodiment of the present application, the linear motor loading platform further includes a rolling support member, the rolling support member is provided in two groups, the rolling support members are respectively provided at the lower end of the support plate, and the rolling support member includes:
[0042] A support frame, the support frame is fixedly mounted on the lower end of the support plate and is located between the two second air bearings;
[0043] The roller is rotatably mounted on the lower end of the support frame and contacts the bottom plate.
[0044] By adopting the above technical solution and utilizing rolling supports, the device can further improve the load capacity of the loading platform. At the same time, by rolling, the roller can walk on the bottom plate to reduce the resistance encountered by the loading platform when it moves.
[0045] In summary, the present application includes at least one of the following beneficial technical effects:
[0046] 1. By setting up an auxiliary guide component and utilizing the loading platform with a gap between the loading platform and the heat-conducting base, the loading platform is not in direct contact with the heat-conducting base, thereby reducing the resistance encountered by the loading platform during movement. At the same time, the auxiliary guide component is utilized to generate a relative lateral force on the loading platform, which has a similar effect to "clamping", so that the loading platform will not deflect during movement. At the same time, the auxiliary guide component can also generate pressure on the bottom plate, and utilize the upward reaction force acting on the loading platform to have a similar effect to "support", thereby improving the "load" capacity of the loading platform.
[0047] 2. By setting up two sets of air bearings as auxiliary guide components, the reaction force of the airflow acting on the guide rail body and the base plate is facilitated, thereby improving the limiting capacity and load capacity of the loading platform. At the same time, the airflow can also accelerate the heat generated between the stator and the mover in the linear motor assembly, thereby realizing the cooling of the motor.
[0048] 3. By setting a heat-conducting base and a water injection cavity, a tangential water pipe is set on the end cover. The water pipe introduces water tangentially into the water injection cavity. The water flow forms a vortex inside the water injection cavity, which accelerates the water flow speed, so that the water flow can take away the heat faster, thereby further improving the heat dissipation effect of the linear motor.
[0049] 4. By setting up two groups of connected hollow tubes and passing buffer solution, when the loading platform moves to one end of the stroke, the buffer solution can be squeezed into the inside of the hollow tube at the other end, so that the resistance block at the other end is further extended. After being squeezed, the resistance block cushions the loading platform, and at the same time, the buffering capacity of the loading platform at the other end of the stroke can be enhanced.
[0050] 5. By setting the first magnetic plate assembly and the second magnetic plate assembly as auxiliary guide assemblies, the first magnetic plate assembly can provide a relative repulsive force between the loading platform and the guide rail body in the horizontal direction, thereby limiting the loading platform in the horizontal direction. At the same time, the second magnetic plate assembly can provide a repulsive force between the loading platform and the bottom plate in the vertical direction, which can also limit the loading platform and is more energy-efficient.

By arranging the material loading platform 3 with a gap from the heat-conducting base 1 and using the auxiliary guiding assemblies 31 to generate pressure on the side and surface of the heat-conducting base 1, the reaction force of the heat-conducting base 1 is utilized to enable the material loading platform 3 to be stably limited without directly contacting the heat-conducting base 1.
[0063] In this embodiment, the heat-conducting base 1 can be a copper component.
[0064] Please continue to refer to Figure 1 and Figure 2, the heat conducting base 1 includes: a guide rail main body 11 and a bottom plate 12. The linear motor assembly 2 is disposed on the upper surface of the guide rail main body 11. The bottom plates 12 are provided in two and are respectively assembled on both sides of the guide rail main body 11. By providing the guide rail main body 11 and the bottom plates 12, a "convex"-shaped heat conducting base 1 is formed, enabling it to better fit the shape of the material loading platform 3 and providing more accurate guidance.
[0065] Please refer to Figure 1 , the material loading platform 3 includes: a material loading plate 32 and support plates 33. The material loading plate 32 is horizontally disposed and is located above the linear motor assembly 2. The support plates 33 are provided in two and are respectively fixedly assembled at both ends of the lower surface of the material loading plate 32. The support plates 33 are vertically disposed and are located on both sides of the guide rail main body 11. By combining the material loading plate 32 and the support plates 33, an inverted U-shaped member is formed and buckled on the heat conducting base 1, enabling the material loading platform 3 to better fit the heat conducting base 1.

The second air bearings 312 are disposed at the lower end of the support plate 33 and are located above the bottom plate 12. Both the first air bearing 311 and the second air bearing 312 are connected to a gas supply device. By providing two opposite first air bearings 311 and ejecting air flow, the reaction force generated by the air flow impacting on the heat conducting base 1 is utilized to improve the stability and limit accuracy during the movement of the material loading platform 3. The air flow ejected by the second air bearing 312 is utilized to improve the supporting performance of the material loading platform 3, thereby improving the load capacity of the material loading platform 3.

[0068] The height limiting strip 13 is internally provided with a ventilation hole 131 extending along its own length direction. The width d1 of the ventilation hole 131 and the thickness d2 of the first air bearing 311 satisfy: d1 < d2. By defining the width of the ventilation, while the ventilation hole 131 can limit the material loading platform 3, the air flow blown out by the air bearing can pass through the ventilation hole 131 to reach the linear motor assembly 2 for heat dissipation.
[0069] Please refer to Figure 3 Figure 3 , a water injection cavity 111 is provided inside the guide rail main body 11.

A spiral water groove 1111 is provided on the inner wall of the water injection cavity 111 along its own length direction. End caps 112 communicating with the water groove 1111 are threadedly assembled at both ends of the guide rail main body 11. A water pipe 113 is assembled on the end cap 112 along its tangential direction. By providing the water injection cavity 111 and cooperating with the heat conduction base 1, the heat of the heat conduction base 1 can be quickly taken away by the high-speed flowing water, thereby further dissipating the heat of the linear motor assembly 2.

[0071] Embodiment 2
[0072] Embodiment 2 has the same basic structure as Embodiment 1, the difference lies in:
[0073] Please refer to Figure 7, the auxiliary guiding component 31 includes: a first magnetic plate component 313 and a second magnetic plate component 314. The first magnetic plate component 313 includes two first magnetic strips 3131 and two groups of first magnetic blocks 3132. The two first magnetic strips 3131 are respectively assembled on both sides of the guide rail main body 11 and extend along the length direction of the guide rail main body 11. The first magnetic blocks 3132 are assembled on one side of the lower end of the support plate 33 close to the heat conduction base 1. The first magnetic strip 3131 and the first magnetic block 3132 repel each other. The second magnetic plate component 314 includes two second magnetic strips 3141 and two groups of second magnetic blocks 3142. The second magnetic strips 3141 are assembled on the upper surface of the bottom plate 12 and extend along the length direction of the bottom plate 12. The second magnetic blocks 3142 are assembled on the lower end of the support plate 33 and are located above the second magnetic blocks 3142. The second magnetic strip 3141 and the second magnetic block 3142 repel each other. By adopting two groups of mutually repulsive magnetic plate components, the repulsive force can also play a role in guiding and limiting, and at the same time, no additional power input is required, reducing energy consumption.
[0074] Embodiment 3
[0075] Embodiment 3 has the same basic structure as Embodiment 1, the difference being that:
[0076] Please refer to Figure 8 , the linear motor loading platform 3 further includes rolling supports 5. Two groups of rolling supports 5 are provided. The rolling supports 5 are respectively arranged at the lower end of the support plate 33. The rolling support 5 includes: a support frame 51 and a roller 52. The support frame 51 is fixedly assembled at the lower end of the support plate 33 and is located between the two second air bearings 312. The roller 52 is rotatably assembled at the lower end of the support frame 51 and contacts the bottom plate 12. By providing the support frame 51 and using the roller 52 to roll on the bottom plate 12, the load capacity of the loading platform 3 can be further provided while ensuring the resistance is reduced.
[0077] In summary, when the device is working, the linear motor component 2 controls the movement of the mover. The mover can drive the loading platform 3 to move along the heat conduction base 1. There is a gap between the loading platform 3 and the heat conduction base 1. Therefore, when the loading platform 3 moves along the heat conduction base 1, the resistance received during the movement can be effectively reduced. At the same time, the first air bearing 311 can blow out relative airflows. By using the reaction force when the airflows act on the heat conduction base 1, the loading platform 3 can be limited in the horizontal direction. At the same time, the second air bearing 312 blows out downward airflows, which can further improve the load capacity of the loading platform 3. In addition, when the airflows are blown out, the heat of the linear motor component 2 can be effectively taken away to avoid heat accumulation.
[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
