Description

Technical Field

[0001] The present application relates to the technical field of loading platforms, and in particular to a linear motor loading platform. Background Art

[0002] Flat linear motors are generally composed of two parts: a stator and a mover. The stator is usually composed of coil windings, which generate a magnetic field when energized; the mover is composed of magnetic conductive materials and permanent magnets (or conductive plates). When alternating current is passed through the stator coil, electromotive force and current will be induced in the mover. According to Ampere's force law, the mover will be subjected to a force perpendicular to the direction of the current and the magnetic field, thereby pushing the mover to move in a straight line.

[0003] When an existing linear motor is used for material transportation, the mover of the linear motor is generally connected to a material loading platform, and the direction and magnitude of the current are controlled to drive the mover to move back and forth.

[0004] When the existing loading platform is driven by a linear motor and moves back and forth, it usually requires support members or limit guide rails for limiting and supporting to ensure stability and structural strength. In this case, there is a large resistance, resulting in increased energy consumption. Summary of the invention

[0005] The present application provides a linear motor loading platform, which can solve the problem that the loading platform is subjected to greater resistance when moving due to the use of limiting guide rails to limit the support of the loading platform.

[0006] The technical solution of the present application is as follows: A linear motor loading platform, comprising: A heat-conducting base, wherein the heat-conducting base is a strip-shaped component; A linear motor assembly is disposed on the upper surface of the heat-conducting base and extends along the length direction of the heat-conducting base; A loading platform is arranged on the mover of the linear motor assembly. The loading platform is an inverted U-shaped component and there is a gap between the loading platform and the heat-conducting base. Auxiliary guide components are respectively arranged on both sides of the lower end of the loading platform. The auxiliary guide components can apply horizontal pressure to the loading platform and perpendicular to the moving direction of the loading platform for guidance, and at the same time apply pressure to the heat-conducting base, and use the reaction force generated by the heat-conducting base on the loading platform to improve the supporting force of the loading platform.

[0007] By adopting the above scheme, the material loading platform with a gap between it and the heat conducting base is used, so that when the linear motor assembly drives the heat conducting base to move, the resistance caused by the friction of the heat conducting base is reduced. At the same time, due to the two auxiliary guide assemblies, the material loading platform can generate a horizontal pressure that is perpendicular to the moving direction of the material loading platform. The two pressure directions are opposite, so that the material loading platform will not shake in the horizontal direction. At the same time, the reaction force generated by the heat-conducting base on the loading platform is used to improve the load capacity of the loading platform, thereby avoiding damage to the linear motor assembly due to excessive product weight.

[0008] In one embodiment of the present application, the thermally conductive base includes: A guide rail body, wherein the linear motor assembly is arranged on an upper surface of the guide rail body; The bottom plate is provided in two pieces and is respectively assembled on both sides of the guide rail body.

[0009] By adopting the above solution, by combining the guide rail body and the bottom plate, a "convex" shaped heat-conducting base is formed, so that it can better fit the shape of the loading platform and guide more accurately.

[0010] In one embodiment of the present application, the loading platform comprises: A material carrier plate, which is arranged horizontally and is located above the linear motor assembly; The supporting plates are provided with two and are respectively fixedly assembled on the two ends of the lower surface of the loading plate. The supporting plates are vertically arranged and located on both sides of the guide rail body.

[0011] By adopting the above solution, the material loading plate and the support plate are combined to form an inverted U-shaped component, which is buckled on the heat-conducting base, so that the material loading platform can fit the heat-conducting base more closely.

[0012] In one embodiment of the present application, the auxiliary guide assembly includes: First air bearings, the first air bearings are arranged in two groups transversely, and the first air bearings are arranged on a side of the support plate close to the guide rail body; The second air bearings are vertically arranged in two groups, and the second air bearings are arranged at the lower end of the support plate and located above the bottom plate; The first air bearing and the second air bearing are both connected to the air supply device.

[0013] By adopting the above solution, by providing the first air bearing and the second air bearing, the two first air bearings can spray airflows in opposite directions, and the reaction force generated by the two opposite airflows impacting the heat-conducting base can prevent the loading platform from malfunctioning in the horizontal direction; At the same time, the second air bearing can spray air to the bottom plate, thereby generating an upward thrust on the loading platform, thereby increasing the overall support force of the device and increasing the load capacity. In addition, the reaction force of the airflow is utilized to avoid direct contact between the loading platform and the heat-conducting base, thereby avoiding the generation of friction resistance.

[0014] In one embodiment of the present application, the heat-conducting base further includes a height-limiting strip, which extends along the length direction of the guide rail body and is arranged on both sides of the guide rail body, and the height-limiting strip is located above the first air bearing.

[0015] By adopting the above solution, a height limiting strip is arranged above the first air bearing, and the height limiting strip can prevent the loading platform from escaping from the heat-conducting base, so as to improve the safety performance of the loading platform.

[0016] In one embodiment of the present application, the height limiting strip has an air hole extending along its length direction, and the width d1 of the air hole and the thickness d2 of the first air bearing satisfy: d1 <d2。

[0017] By adopting the above technical solution, by opening air holes inside the height limit strip, when the first air bearing and the second air bearing eject airflow, the airflow can pass through the air holes and reach the linear motor assembly, so that the airflow ejected from the first air bearing and the second air bearing can have the effect of dissipating heat for the linear motor assembly.

[0018] In one embodiment of the present application, a water injection cavity is opened inside the guide rail body, and the water injection cavity extends along the length direction of the guide rail body. The inner wall of the water injection cavity is provided with a spiral water groove along its own length direction. The two ends of the guide rail body are threadedly equipped with end covers connected to the water groove, and the end covers are equipped with water pipes along their own tangential direction.

[0019] By adopting the above technical solution, a water injection cavity is opened inside the guide rail body, and water pipes are arranged at both ends of the water injection cavity. When water flows through the water pipes arranged tangentially along the end cover, the water flow can pass through the end cover into the water injection cavity and form a vortex, thereby increasing the speed of the water flow, thereby accelerating the heat exchange efficiency of the water flow, and thereby reducing the heat of the linear motor assembly located on the heat-conducting base.

[0020] In one embodiment of the present application, the upper surfaces of both ends of the guide rail body are provided with limit buffer seats, and the two limit buffer seats are respectively located at the two ends of the linear motor assembly, and the limit buffer seats include: A fixing seat, the fixing seat is fixedly assembled on the upper surface of the guide rail body; A hollow tube, the hollow tube is penetrated and arranged on the fixed seat, a piston is arranged inside the hollow tube, a connecting shaft is coaxially assembled on one side of the piston, one end of the connecting shaft penetrates the side of the hollow tube close to the loading platform and extends to the outside of the hollow tube, one end of the connecting shaft is connected to a resistance block, the other sides of the two hollow tubes are connected through a connecting tube, and the connecting tube is filled with a buffer solution.

[0021] By adopting the above technical solution, when the loading platform moves to the end of the stroke, the loading platform generates an impact on the side located at the end of the stroke, thereby pushing the resistance block on this side to retract toward the direction of the hollow tube. At the same time, the resistance block pushes the piston to move along the hollow tube, so that the buffer solution inside the hollow tube is pushed to the inside of the hollow tube on the other side through the connecting tube. The buffer solution column can push the piston inside the hollow tube on the other side to move and extend the connecting shaft on the other side, so that when the loading platform moves to the end of the stroke on the other side, the connecting shaft extended on the other side has sufficient buffer distance.

[0022] In one embodiment of the present application, the auxiliary guide assembly includes: A first magnetic plate assembly, the first magnetic plate assembly comprising two first magnetic strips and two groups of first magnetic blocks, the two first magnetic strips are respectively mounted on both sides of the guide rail body and extend along the length direction of the guide rail body, the first magnetic block is mounted on a side of the lower end of the support plate close to the heat conductive base, and the first magnetic strips and the first magnetic blocks repel each other; The second magnetic plate assembly includes two second magnetic strips and two groups of second magnetic blocks. The second magnetic strips are mounted on the upper surface of the base plate and extend along the length direction of the base plate. The second magnetic blocks are mounted on the lower end of the support plate and are located above the second magnetic blocks. The second magnetic strips and the second magnetic blocks repel each other.

[0023] By adopting the above technical solution, the mutual repulsion between the first magnetic plate components is utilized to ensure that the loading platform and the guide rail body can limit the loading platform in the horizontal direction through repulsion in opposite directions without contacting each other; 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.

[0024] 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: 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; The roller is rotatably mounted on the lower end of the support frame and contacts the bottom plate.

[0025] 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.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0035] See also Figure 1 , Figure 2 and Figure 4The heat-conducting base 1 is a strip-shaped component, the linear motor assembly 2 is arranged on the upper surface of the heat-conducting base 1 and extends along the length direction of the heat-conducting base 1, the loading platform 3 is arranged on the mover of the linear motor assembly 2, the loading platform 3 is an inverted U-shaped component, and there is a gap between the loading platform 3 and the heat-conducting base 1, and auxiliary guide components 31 are respectively arranged on both sides of the lower end of the loading platform 3, and the auxiliary guide components 31 can apply horizontal and perpendicular pressure to the loading platform 3 in the direction of travel of the loading platform 3 for guiding, and at the same time apply pressure to the heat-conducting base 1, and utilize the reaction force generated by the heat-conducting base 1 on the loading platform 3 to improve the supporting force of the loading platform 3, by providing a loading platform 3 with a gap between the loading platform 3 and the heat-conducting base 1, and utilizing the auxiliary guide components 31 to generate pressure on the side and surface of the heat-conducting base 1, and utilizing the reaction force of the heat-conducting base 1 so that the loading platform 3 can be stably limited without direct contact with the heat-conducting base 1.

[0036] In this embodiment, the heat-conducting base 1 can be a copper component.

[0037] Please continue reading Figure 1 and Figure 2 The heat-conducting base 1 includes: a guide rail body 11 and a base plate 12. The linear motor assembly 2 is arranged on the upper surface of the guide rail body 11. The base plates 12 are provided in two numbers and are respectively assembled on both sides of the guide rail body 11. By setting the guide rail body 11 and the base plate 12, a "convex"-shaped heat-conducting base 1 is formed, so that it can better fit the shape of the loading platform 3 and guide more accurately.

[0038] See also Figure 1 The loading platform 3 includes: a loading plate 32 and a support plate 33. The loading plate 32 is horizontally arranged and located above the linear motor assembly 2. Two support plates 33 are provided and are respectively fixedly assembled at the two ends of the lower surface of the loading plate 32. The support plates 33 are vertically arranged and located on both sides of the guide rail body 11. By combining the loading plate 32 and the support plate 33, an inverted U-shaped component is formed and buckled on the heat-conducting base 1, so that the loading platform 3 can fit the heat-conducting base 1 more closely.

[0039] See also Figure 1, the auxiliary guiding assembly 31 includes: a first air bearing 311 and a second air bearing 312. The first air bearings 311 are horizontally arranged in two groups, and the first air bearings 311 are arranged on one side of the support plate 33 close to the guide rail body 11. The second air bearings 312 are vertically arranged in two groups, and the second air bearings 312 are arranged at the lower end of the support plate 33 and 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 setting two opposite first air bearings 311 and ejecting air flow, the reaction force generated by the air flow impacting on the heat conduction 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 support performance of the material loading platform 3, thereby improving the load capacity of the material loading platform 3.

[0040] Please continue to refer to Figure 1 , the heat conduction base 1 further includes a height limiting strip 13. The height limiting strip 13 extends along the length direction of the guide rail body 11 and is arranged on both sides of the guide rail body 11. The height limiting strip 13 is located above the first air bearing 311. The height limiting strip 13 can prevent the material loading platform 3 from disengaging from the heat conduction base 1 to improve the use safety performance of the material loading platform 3.

[0041] The height limiting strip 13 is internally provided with air holes 131 extending along its own length direction. The width d1 of the air holes 131 and the thickness d2 of the first air bearing 311 satisfy: d1 < d2. By limiting the width of the air permeability, the air holes 131 can play a role in limiting the material loading platform 3 while enabling the air flow blown out by the air bearing to pass through the air holes 131 to reach the linear motor assembly 2 for heat dissipation.

[0042] Please refer to Figure 3 , the guide rail body 11 is internally provided with a water injection cavity 111. The water injection cavity 111 extends along the length direction of the guide rail body 11. A spiral water tank 1111 is arranged on the inner wall of the water injection cavity 111 along its own length direction. End caps 112 communicating with the water tank 1111 are threadedly assembled at both ends of the guide rail body 11. Water pipes 113 are assembled on the end caps 112 along their tangential directions. 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 carried away by the high-speed flowing water, thereby further dissipating the heat of the linear motor assembly 2.

[0043] Please refer to Figure 6, the upper surfaces of both ends of the guide rail body 11 are provided with limited buffer seats 4, and the two limited buffer seats 4 are respectively located at the two ends of the linear motor assembly 2, and the limited buffer seats 4 include: a fixed seat 41 and a hollow tube 42, the fixed seat 41 is fixedly assembled on the upper surface of the guide rail body 11, the hollow tube 42 is penetrated and arranged on the fixed seat 41, a piston 43 is arranged inside the hollow tube 42, and a connecting shaft 44 is coaxially assembled on one side of the piston 43, and one end of the connecting shaft 44 penetrates the hollow tube 42 near the loading platform 3 side, and extends to the outside of the hollow tube 42, one end of the connecting shaft 44 is connected with a resistance block 45, the other sides of the two hollow tubes 42 are connected through a connecting tube 46, and the inside of the connecting tube is filled with a buffer solution 47. By setting two relative and mutually connected limit buffer seats 4, not only can the limit buffer seat 4 have a buffering effect, but also after the resistance block 45 at one end is squeezed, the buffer solution 47 will move to the other end, and drive the buffer solution 47 column at the other end to push out the piston 43, thereby extending the buffer formation at the other end and improving the buffering effect.

[0044] Example 2 The basic structure of Example 2 is the same as that of Example 1, except that: See also Figure 7 The auxiliary guide assembly 31 includes: a first magnetic plate assembly 313 and a second magnetic plate assembly 314, wherein the first magnetic plate assembly 313 includes two first magnetic strips 3131 and two groups of first magnetic blocks 3132, wherein the two first magnetic strips 3131 are respectively mounted on both sides of the guide rail body 11 and extend along the length direction of the guide rail body 11, and the first magnetic block 3132 is mounted on the lower end of the support plate 33 close to the heat-conducting base 1, and the first magnetic strips 3131 and the first magnetic blocks 3132 repel each other, and the second magnetic plate assembly 314 includes two first magnetic strips 3131 and two groups of first magnetic blocks 3132. Component 314 includes two second magnetic strips 3141 and two groups of second magnetic blocks 3142. The second magnetic strips 3141 are mounted on the upper surface of the base plate 12 and extend along the length direction of the base plate 12. The second magnetic block 3142 is mounted on the lower end of the support plate 33 and is located above the second magnetic block 3142. The second magnetic strips 3141 and the second magnetic block 3142 repel each other. By adopting two groups of repelling magnetic plate components, the repulsive force can also play a guiding and limiting role. At the same time, no additional power input is required, thereby reducing energy consumption.

[0045] Example 3 The basic structure of Example 3 is the same as that of Example 1, except that: See also Figure 8The linear motor loading platform 3 also includes a rolling support member 5, and the rolling support member 5 is arranged in two groups. The rolling support members 5 are respectively arranged at the lower end of the support plate 33. The rolling support member 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 with the bottom plate 12. By setting the support frame 51 and using the roller 52 to roll on the bottom plate 12, it is possible to ensure that the load capacity of the loading platform 3 is further provided while reducing the resistance.

[0046] To sum up, when the device is working, the linear motor assembly 2 controls the movement of the mover, and the mover can drive the loading platform 3 to move along the heat-conducting base 1. A gap is left between the loading platform 3 and the heat-conducting base 1. Therefore, when the loading platform 3 moves along the heat-conducting base 1, it can effectively reduce the resistance encountered during the movement process. At the same time, the first air bearing 311 can blow out a relative airflow, and use the reaction force of the airflow acting on the heat-conducting base 1 to limit the loading platform 3 in the horizontal direction. At the same time, the second air bearing 312 blows out a downward airflow, which can further improve the load capacity of the loading platform 3. In addition, when the airflow is blown out, it can also effectively take away the heat of the linear motor assembly 2 to avoid heat accumulation.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
