The base 1 has a first surface (not shown) and a second surface (not shown) disposed opposite each other along a fifth direction L5. The third drive device 3 is disposed on the first surface, and the fourth drive device 5 is disposed on the second surface. The first drive unit 2, the second drive unit 4, the third drive unit 3, and the fourth drive unit 5 are connected together via the base 1. These three drive units can drive external objects independently. The drive platform 100, when applied to a production line, allows for a compact production line layout and improves space utilization. Furthermore, since the third drive unit 3 and the fourth drive unit 5 are located on either side of the base 1 along the fifth direction L5, the space utilization of the production line in the fifth direction L5 can be further improved.

[0028] In some embodiments, the first driving device 2 is used to drive the first external object to move along the first direction L1, including the first driving device 2 driving the first external object to reciprocate along the first direction L1.

[0032] In some embodiments, the first angle is 90 degrees, that is, the third direction L3 is perpendicular to the first direction L1.

[0033] In some embodiments, the fifth direction L5 is perpendicular to the first direction L1 and the fifth direction L5 is perpendicular to the third direction L3.

[0034] In some embodiments, the first direction L1 is parallel to the ground, the third direction L3 is parallel to the ground, and the fifth direction L5 is perpendicular to the ground. By setting the third driving device 3 on the first surface and the fourth driving device 5 on the second surface, the space in the direction perpendicular to the ground can be effectively utilized, thereby improving space utilization.

[0035] The base 1 described above is used for mounting the first drive device 2, the second drive device 4, the third drive device 3, and the fourth drive device 5. In some embodiments, please refer to... Figure 1 The base 1 is provided with an opening 11, which is used for setting a fifth external object. The fifth external object can be a lifting device, a detection device, or a combination of a lifting device and a detection device, etc.

[0036] In some embodiments, the first drive device 2, the second drive device 4, the third drive device 3 and the fourth drive device 5 are arranged around the opening 11, thereby enabling the proper use of the base 1.

[0037] For the first drive device 2 mentioned above, please refer to Figure 2When the fourth direction L4 and the third direction L3 are opposite, in some embodiments, the first driving device 2 includes a first base 21, a first platform 22, a first side plate 23, a first metal part 24, a first magnetic element 25, a first motor stator 26, a first motor mover 27, and a first air buoyancy assembly 28; the first base 21 is disposed on the base 1 along the first direction L1; the first motor stator 26 is disposed on the base 1; the first motor mover 27 is disposed on the first platform 22, and moves relative to the first motor stator 26 along the first direction L1; the first platform 22 includes a first plate 221 and a second plate 222 connected together, the end of the second plate 222 away from the first plate 221 is connected to the first side plate 23, and the first platform 22 and the first side plate 23 are disposed around the first base 21; the first metal part 24 is disposed on the first base 21; the first magnetic element 25, the first magnetic element 26, the first motor stator 27, the first motor mover 27, and the first air buoyancy assembly 28. Component 25 and the first metal part 24 are disposed opposite to each other; the first magnetic component 25 is disposed on the first plate 221 for adsorbing the first metal part 24 along a third direction L3, and / or, the first magnetic component 25 is disposed on the second plate 222 for adsorbing the first metal part 24 along a fifth direction L5, and / or, the first magnetic component 25 is disposed on the first side plate 23 for adsorbing the first metal part 24 along the fourth direction L4; the first air flotation assembly 28 is disposed on the first base 21, the first air flotation assembly 28 is used to output force towards the first plate 221 along a third direction L3, and / or, the first air flotation assembly 28 is used to output force towards the second plate 222 along the fifth direction L5, and / or, the first air flotation assembly 28 is used to output force towards the first side plate 23 along the fourth direction L4; the first platform 22 is used for the first external object.

[0038] In some embodiments, the first plate 221 and the second plate 222 are arranged vertically.

[0039] The force exerted on the first plate 221 by the first metal component 24 is opposite to the force exerted by the first air buoyancy component 28, thus ensuring a stable relative position between the first plate 221 and the first base 21. When the first plate 221 is moved along the first direction L1 by the first motor stator 26, the relative motion between the first plate 221 and the first base 21 is stable and free from frictional loss. Furthermore, the forces exerted on the first plate 221 by the first metal component 24 and the first air buoyancy component 28 enable precise movement of the first plate 221.

[0040] Similarly, the force exerted on the second plate 222 by the first metal component 24 is opposite to the force exerted on it by the first air buoyancy component 28, thus ensuring a stable relative position between the second plate 222 and the first base 21. When the second plate 222 is moved along the first direction L1 by the first motor stator 26, the relative motion between the second plate 222 and the first base 21 is stable and free from frictional loss. Furthermore, the forces exerted on the second plate 222 by the first metal component 24 and the first air buoyancy component 28 enable precise movement of the second plate 222.

[0041] Similarly, the force exerted on the first side plate 23 by the first metal component 24 is opposite to the force exerted on it by the first air buoyancy assembly 28, thus ensuring a stable relative position between the first side plate 23 and the first base 21. When the first side plate 23 is moved along the first direction L1 by the first motor stator 26, the relative movement between the first side plate 23 and the first base 21 is stable and free from frictional loss. Furthermore, the force exerted on the first side plate 23 by the first metal component 24 and the first air buoyancy assembly 28 enables precise movement of the first side plate 23.

[0042] Since the first plate 221 can move stably, without friction loss, and with precision relative to the first base 21, the first external object set on the first platform 22 can move stably, without friction loss, and with precision relative to the base 1.

[0043] In some embodiments, the number of the first magnetic element 25 is three, one magnetic element 25 is disposed on the first plate 221, one magnetic element 25 is disposed on the second plate 222, and one magnetic element 25 is disposed on the first side plate 23; the number of the first metal part 24 is three, one first metal part 24 and one first magnetic element 25 are disposed opposite to each other. When the number of the first metal part 24 and the number of the first magnetic element 25 are three, the first external object disposed on the first platform 22 can move more stably, without friction loss, and with precision relative to the base 1.

[0044] In some embodiments, the number of the first air flotation components 28 is three, one with its working surface facing the first plate 221, one with its working surface facing the second plate 222, and one with its working surface facing the first side plate 23. Having three first air flotation components 28 enables a first external object mounted on the first platform 22 to move more stably, without frictional loss, and with precision relative to the base 1.

[0045] In some embodiments, the first magnetic element 25 includes a permanent magnet; however, the first magnetic element 25 is not limited to a permanent magnet.

[0046] In some embodiments, the first metal element 24 includes a steel bar; however, the first metal element 24 is not limited to a steel bar.

[0047] In some embodiments, the first air bearing assembly 28 includes an air bearing with its working surface facing the first plate 221 of the first platform 22, and / or the working surface of the air bearing facing the second plate 222 of the first platform 22, and / or the working surface of the air bearing facing the first side plate 23.

[0048] In some embodiments, the working surface of the air bearing is provided with a plurality of through holes, which are connected to an external air source. By adjusting the pressure of the external air source, the force exerted by the air bearing on the first plate 221 of the first platform 22, and / or on the second plate 222 of the first platform 22, and / or on the first side plate 23 can be adjusted.

[0049] In some embodiments, the first driving device 2 further includes a mounting block (not shown); the mounting block is disposed on the first plate 221, the first magnetic element 25 is detachably mounted to the mounting block, and the mounting block is used to adjust the distance between the first magnetic element 25 and the first metal element along the third direction L3; and / or, the mounting block is disposed on the second plate 222, the first magnetic element 25 is detachably mounted to the mounting block, and the mounting block is used to adjust the distance between the first magnetic element 25 and the first metal element along the fifth direction L5; and / or, the mounting block is disposed on the first side plate 23, the first magnetic element 25 is detachably mounted to the mounting block, and the mounting block is used to adjust the distance between the first magnetic element 25 and the first metal element along the third direction L3.

[0050] It is understood that when the number of the first metal parts 24 is three and the number of the first magnetic elements 25 is three, the number of mounting blocks is three. One mounting block is set on the first plate 221 of the first platform 22, one mounting block is set on the second plate 222 of the first platform 22, and one mounting block is set on the first side plate 23.

[0051] Regarding the second driving device 4 described above, please refer to some embodiments. Figure 1 The second driving device 4 is symmetrically arranged on the base 1 with the first driving device 2.

[0052] The structure of the second drive device 4 can be the same as that of the first drive device 2. For example, when the fourth direction L4 and the third direction L3 are opposite, the second drive device 4 includes a second base (not shown), a second platform (not shown), a second side plate (not shown), a second metal part (not shown), a second magnetic element (not shown), a second motor stator (not shown), a second motor mover (not shown), and a second air buoyancy assembly (not shown); the second base is disposed on the base 1 along the first direction L1; the second motor stator is disposed on the base 1; the second motor mover is disposed on the second platform, and moves relative to the second motor stator along the second direction L2; the second platform includes a connected third plate and a fourth plate, the end of the fourth plate away from the third plate is connected to the second side plate, and the second platform and the second side plate are disposed around the second base; the second metal part is disposed on the... The second base is described; the second magnetic element and the second metal part are disposed opposite to each other; the second magnetic element is disposed on the third plate for adsorbing the second metal part along the fourth direction L4, and / or, the second magnetic element is disposed on the fourth plate for adsorbing the second metal part along the fifth direction L5, and / or, the second magnetic element is disposed on the second side plate for adsorbing the second metal part along the third direction L3; the second air flotation assembly is disposed on the second base, and the second air flotation assembly is used to output force towards the third plate along the fourth direction L4, and / or, the second air flotation assembly is used to output force towards the fourth plate along the fifth direction L5, and / or, the second air flotation assembly is used to output force towards the second side plate along the third direction L3; the second platform is used for mounting the second external object. The second external object mounted on the second platform can move stably, without frictional loss, and with precision relative to the base 1.

[0053] It is understandable that, similar to the first driving device 2, the number of the second metal parts and the second magnetic elements in the second driving device 4 can be set to three, and the number of the second air buoyancy components can be set to three, so that the second external object set on the second platform can move more stably, without friction loss, and with precision relative to the base 1.

[0054] In some embodiments, the second magnetic element includes a permanent magnet; however, the second magnetic element is not limited to a permanent magnet.

[0055] In some embodiments, the second metal element includes a steel bar; however, the second metal element is not limited to a steel bar.

[0056] In some embodiments, the second air bearing assembly includes an air bearing, the working surface of which faces the third plate of the second platform, and / or the working surface of which faces the fourth plate of the second platform, and / or the working surface of which faces the second side plate.

[0057] Of course, the second drive unit 4 can also be equipped with a mounting block, which will not be elaborated here.

[0058] It is worth noting that in some embodiments, the second external object and the first external object are the same object, in which case the first driving device 2 and the second driving device 4 can drive the same external object simultaneously.

[0059] The aforementioned drive platform 100 also includes a first column 6 and a second column 7. The first column 6 and the second column 7 are disposed opposite each other on the first surface of the base 1 along a third direction L3. One end of the third drive device 3 is disposed on the first column 6, and the other end of the third drive device 3 is disposed on the second column 7. Thus, by setting the dimensions of the first column 6 and the second column 7 in the fifth direction L5, the distance between the third drive device 3 and the base 1 in the fifth direction L5 can be adjusted.

[0060] For the third drive unit 3 mentioned above, please refer to Figure 1 and Figure 3When the second direction L2 is opposite to the first direction L1, in some embodiments, the third driving device 3 includes a third base 30, a third platform 31, a third lower plate 32, a third upper plate 33, a third side plate 34, a third magnetic element 35, a third metal part 36, a third air flotation assembly 37, and a third motor stator assembly 38; along the third third direction L3, one end of the third base 30 is disposed on the first column 6, and the other end of the third base 30 is disposed on the second column 7; the stator end of the third motor stator assembly 38 is disposed on the... The third base 30 is described; the moving end of the third motor stator assembly 38 is disposed on the third side plate 34, and along the third direction L3, the moving end of the third motor stator assembly 38 moves relative to the stator end of the third motor stator assembly 38; the third platform 31 and the third side plate 34 are arranged opposite each other along the first direction L1, and the third lower plate 32 and the third upper plate 33 are arranged opposite each other along the fifth direction L5; the third platform 31, the third lower plate 32, the third side plate 34 and the third upper plate 33 are connected in sequence, and the third platform 31... A third lower plate 32, a third side plate 34, and a third upper plate 33 are arranged around the third base 30; a third metal piece 36 is disposed on the third base 30; a third magnetic element 35 and a third metal piece 36 are disposed opposite each other; the third magnetic element 35 is disposed on the third platform 31 for adsorbing the third metal piece 36 along a first direction L1, and / or, the third magnetic element 35 is disposed on the third upper plate 33 for adsorbing the third metal piece 36 along a fifth direction L5, and / or, the third magnetic element 35 is disposed on the third platform 31. The third side plate 34 is used to adsorb the third metal part 36 along the second direction L2; the third air flotation component 37 is disposed on the third base 30, and the third air flotation component 37 is used to output force towards the third platform 31 along the first direction L1, and / or, the third air flotation component 37 is used to output force towards the third upper plate 33 along the fifth direction L5, and / or, the third air flotation component 37 is used to output force towards the third side plate 34 along the second direction L2; the third platform 31 is used for the placement of the third external object.

[0061] The force exerted on the third platform 31 by the third metal component 36 is opposite to the force exerted by the third air buoyancy component 37, thus stabilizing the relative position of the third platform 31 and the third base 30. When the third platform 31 is driven by the stator end of the third motor stator assembly to move along the third direction L3, the relative motion between the third platform 31 and the third base 30 is stable and without frictional loss. Furthermore, the force exerted on the third platform 31 by the third metal component 36 and the third air buoyancy component 37 enables precise movement of the third plate.

[0062] Similarly, the force exerted on the third upper plate 33 by the third metal component 36 is opposite to the force exerted on it by the third air buoyancy component 37, thus ensuring a stable relative position between the third upper plate 33 and the third base 30. When the third upper plate 33 is moved along the third direction L3 by the stator end of the third motor stator assembly 38, the relative motion between the third upper plate 33 and the third base 30 is stable and free from frictional loss. Furthermore, the force exerted on the third upper plate 33 by the third metal component 36 and the third air buoyancy component 37 enables precise movement of the third upper plate 33.

[0063] Similarly, the force exerted on the third side plate 34 by the third metal component 36 is opposite to the force exerted on it by the third air buoyancy assembly 37, thus ensuring a stable relative position between the third side plate 34 and the third base 30. When the third side plate 34 is moved along the third direction L3 by the stator end of the third motor stator assembly 38, the relative motion between the third side plate 34 and the third base 30 is stable and free from frictional loss. Furthermore, the force exerted on the third side plate 34 by the third metal component 36 and the third air buoyancy assembly 37 enables precise movement of the third side plate 34.

[0064] Because the third platform 31 can move stably, without friction loss, and with precision relative to the third base 30, the third external object set on the third platform 31 can move stably, without friction loss, and with precision relative to the base 1.
