DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The technical ideas in the embodiments of the present invention will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can obtain without making inventive efforts are all included in the scope of protection of the present invention. Example 1

[0020] In an embodiment of the present invention, a multi-mover direct drive transmission system 100 is provided. The multi-mover direct drive transmission system 100 is data-connected to an external control system 200. The multi-mover direct drive transmission system 100 is powered by an external power source 300.

[0021] As shown in FIGS. 1 to 4, specifically, the multi-mover direct drive transmission system 100 includes a stator unit 1, a guide rail 2, a mover unit 3, and a conductive bar 4.

[0022] The stator unit 1 is formed by sequentially connecting multiple segments to form an integrated unit.

[0023] Each of the stator units 1 includes a stator 11 , a magnet steel 12 and a second position feedback device 13 .

[0024] The stator 11 is made of a magnetically permeable material.

[0025] The magnet steel 12 is fixed to the stator 11. The magnet steel 12 is located on the side of the stator 11 closer to the mover unit 3, i.e., the magnet steel 12 and the guide rail 2 are located on the same side of the stator 11. There are a plurality of the magnet steels 12, and the plurality of the magnet steels 12 are sequentially connected to be integrated.

[0026] The second position feedback device 13 is fixed to the stator 11. The second position feedback device 13 is data-connected to the control system 200. The second position feedback device 13 is used to sense the position of the mover unit 3 and provide it to the external control system 200.

[0027] The guide rail 2 is provided so as to be attached to the stator unit 1. Specifically, the guide rail 2 is provided so as to be attached to the stator 11.

[0028] There are two guide rails 2. The two guide rails 2 are installed parallel to and spaced apart from each other along the extension direction of the stator unit 1. The two guide rails 2 are located on the same horizontal plane, which is advantageous for allowing the mover unit 3 to move smoothly.

[0029] The mover unit 3 is connected to the guide rail 2 so as to be capable of sliding.

[0030] There are a plurality of the mover units 3. The plurality of mover units 3 helps to improve the usage efficiency of the multi-mover direct drive transmission system 100. Of course, this is not limited thereto, and only one mover unit 3 may be provided.

[0031] Specifically, each of the mover units 3 includes a mover 31 , a winding 32 , a driving device 33 , a power supply unit 34 , and a first position feedback device 35 .

[0032] The mover 31 is made of a magnetically permeable material. The mover 31 is connected to the guide rail 2 so as to be capable of sliding.

[0033] The winding 32 is fixed to the mover 31. The winding 32 is disposed opposite to and spaced apart from the magnet steel 12. The winding 32 drives the magnet steel 12 so that the mover unit 3 moves along the guide rail 2.

[0034] The driving device 33 is electrically connected to the winding 32 to control the energization or cutoff of the winding 32. The driving device 33 realizes data connection with the control system 200 through wireless communication. This structure avoids the stator being in a state of frequent energization and cutoff as in the prior art, and directly controls the energization or cutoff of the winding 32 by the mover unit 3, thereby simplifying the control system 200 and helping to make the multi-mover direct drive transmission system 100 of the present invention easier to control and use, and also helps to reduce the number of devices used in the multi-mover direct drive transmission system 100, simplifying the structure and reducing costs.

[0035] The power supply unit is used for connection to the power source 300. The power source 300 supplies power to the mover unit 3 via the power supply unit .

[0036] In the first embodiment, the power supply unit 34 is a movable cable. One end of the power supply unit 34 is electrically connected to the winding 32 and the driving device 33 respectively, and the other end of the power supply unit 34 is slidably connected to the conductive bar 4, forming a movable conductive structure. The movable conductive structure can realize the control of energizing or de-energizing the winding 32, which simplifies the control system 200 and helps to facilitate the control and use of the multi-mover direct drive transmission system 100 of the present invention.

[0037] Specifically, the power supply unit 34 includes a first segment 341 fixed to the mover 31, a second segment 342 bending and extending from the first segment 341 in a direction away from the mover 31, and a third segment 343 bending and extending from the second segment 342, forming a movable conductive structure in which the third segment 343 and the conductive bar 4 are slidably connected. This structure helps to realize that the power supply unit 34 moves following the mover unit 3, and is also simple in structure.

[0038] The first position feedback device is fixed to the mover 31. The first position feedback device is electrically connected to the power supply unit .

[0039] The first position feedback device 35, the second position feedback device 13, the winding 32 and the magnet steel 12 are all located between the two guide rails 2. The first position feedback device 35 is installed opposite the second position feedback device 13 so that the second position feedback device 13 senses position information of the first position feedback device 35 and transmits the position information to the control system 200.

[0040] The conductive bar 4 is used for connection to the power source 300. The conductive bar 4 is installed at a distance from the stator unit 1 and parallel to the extension direction of the stator unit 1. Example 2

[0042] As shown in FIGS. 5 and 6, a power supply unit 34a of the multi-mover direct drive transmission system 100a is different from the power supply unit 34 of the multi-mover direct drive transmission system 100 of the first embodiment.

[0043] The power supply unit 34a of the multi-mover direct drive transmission system 100a of the second embodiment of the present invention is a battery. The battery is a battery with an electric capacity, can be directly installed, and does not need to be charged separately, such as a lithium battery or an accumulator.

[0044] Here, the power supply unit 34a is electrically connected to the winding 32a and the driving device 33a, respectively.

[0045] Of course, since the power supply unit 34a adopts a battery, the power supply unit 34a of the multi-mover direct drive transmission system 100a does not need to be provided with the conductive bar 4 of the multi-mover direct drive transmission system 100 in the first embodiment.

[0046] The multi-mover direct drive transmission system 100a in the second embodiment of the present invention can achieve beneficial effects corresponding to the respective embodiments of the multi-mover direct drive transmission system 100 in the first embodiment, which need not be described again here to avoid duplication.

[0048] As shown in FIGS. 7 and 8, the power supply unit 34b of the multi-mover direct drive transmission system 100b is different from the power supply unit 34a of the multi-mover direct drive transmission system 100a of the second embodiment.

[0049] The power supply unit 34b is a wirelessly chargeable battery, and is electrically connected to the winding 32b and the driving device 33b, respectively.

[0050] In order to realize wireless charging of the power supply unit 34b, the multi-mover direct drive transmission system 100b of the embodiment 3 of the present invention has one additional charging device compared to the multi-mover direct drive transmission system 100a of the embodiment 2. Specifically, the multi-mover direct drive transmission system 100b further includes a wireless charging device 5 for wirelessly charging the power supply unit 34b, and at least a part of the stroke of the power supply unit 34b moving along the guide rail 2b is within the wireless charging range of the wireless charging device 5.

[0051] The multi-mover direct drive transmission system 100b of the third embodiment of the present invention can achieve beneficial effects corresponding to those of the embodiments of the multi-mover direct drive transmission system 100 of the first embodiment, which need not be described again here to avoid duplication.

[0052] Compared with the prior art, the multi-mover direct drive transmission system of the present invention has a magnet steel installed in the stator unit, a winding installed in the mover unit, the winding facing the magnet steel at a distance, and the winding drives the magnet steel so that the mover unit moves along the guide rail.
