[0041] See also Figure 1A and Figure 1B , Figure 1A and Figure 1B A flat motor 100 provided in an embodiment of the present application is shown.

[0042] It can be understood that the flat motor 100 is a linear motor that can generate magnetic force through the magnetic effect of electric current and drive the mover to perform linear motion through the magnetic force.

[0043] In an embodiment of the present application, the flat motor 100 may include a stator component 101 and a mover component 102. The stator component 101 extends along a first direction, and a plurality of permanent magnets are arranged in the stator component 101 or the stator component 101 is configured as a permanent magnet. The mover component 102 is located on one side of the stator component 101. An electromagnet may be arranged in the mover component 102. The electromagnet in the mover component 102 generates a magnetic field after being energized, and the stator component 101 may generate a magnetic field. Under the action of the two magnetic fields, the mover component 102 may move along the first direction according to the principle that like poles repel each other and opposite poles attract each other.

[0044] It can be understood that the length direction of the stator component 101 and the movable component 102 can be defined as the first direction, the width direction of the movable component 102 can be defined as the second direction, and the height direction of the movable component 102 can be defined as the third direction. For example, as shown in FIG. 1 and FIG. 2, the first direction can be the X direction and the opposite direction, the second direction can be the Y direction and the opposite direction, and the third direction can be the Z direction and the opposite direction.

[0045] It can be understood that in some cases, the mover member 102 can be movably connected to the stator member 101. In other cases, the mover member 102 and the stator member 101 can be spaced apart along the third direction.

[0046] In an embodiment of the present application, the flat motor 100 may further include a liquid cooling device 103. The liquid cooling device 103 is fixedly mounted on the moving component 102. The liquid cooling device 103 can receive and output cooling liquid. The heat generated by the moving component 102 during operation can be transferred to the liquid cooling device 103, and the liquid cooling device 103 can transfer the heat to the cooling liquid. The cooling liquid that absorbs the heat can flow out of the liquid cooling device 103, and the cooling liquid that does not absorb the heat can enter the liquid cooling device 103. In this way, the heat dissipation of the moving component 102 can be achieved through heat transfer between the moving component 102 and the liquid cooling device 103, and between the liquid cooling device 103 and the cooling liquid.

[0047] It can be understood that the liquid cooling device 103 is installed on the moving part 102, that is, the liquid cooling device 103 is located outside the moving part 102. When the liquid cooling device 103 has problems such as leakage, and the staff needs to investigate and solve the problem, the staff can inspect and maintain the liquid cooling device 103 in the space outside the moving part 102 without disassembling the moving part 102. In this way, the convenience of maintaining the liquid cooling device 103 can be improved, and the probability of the moving part 102 being damaged due to the leakage of coolant into the inside of the moving part 102 can be reduced.

[0048] In the embodiment of the present application, there is no specific limitation on the installation position of the liquid cooling device 103 on the moving component 102. Figure 1A As shown, the liquid cooling device 103 may be installed on a side of the moving part 102 away from the stator part 101. For another example, the liquid cooling device 103 may be installed on a side of the moving part 102 in the second direction.

[0049] In the embodiments of the present application, there is no specific limitation on the fixing method during the fixed connection and fixed installation. For example, the fixing method may include, but is not limited to, screw fixing, welding fixing, buckle fixing, etc.

[0050] Please also read Figure 2A and Figure 2B In some embodiments, the liquid cooling device 103 may include a liquid cooling box 10, a first end cover 20, and a second end cover 30. The liquid cooling box 10 extends along a first direction. The liquid cooling box 10 may be made of a heat-conducting metal material.

[0051] The liquid cooling box 10 has a liquid inlet channel 11 and a liquid outlet channel 12. The liquid inlet channel 11 and the liquid outlet channel 12 both extend in a first direction. The liquid inlet channel 11 and the liquid outlet channel 12 can be arranged at intervals in a direction perpendicular to the first direction (e.g., a second direction and / or a third direction). A connecting groove 13 is provided at the first end of the liquid cooling box 10, and the connecting groove 13 can connect the liquid inlet channel 11 and the liquid outlet channel 12.

[0052] The first end of the liquid cooling box 10 in the first direction is provided with a first groove 14. The first groove 14 can be connected with the liquid inlet channel 11, the liquid outlet channel 12 and the connecting groove 13. The connecting groove 13 can be provided on the inner wall of the first groove 14 and extend to the inner walls of the liquid inlet channel 11 and the liquid outlet channel 12. At least part of the structure of the first end cover 20 is accommodated in the first groove 14, and the first end cover 20 is fixedly connected to the liquid cooling box 10.

[0053] The second end of the liquid cooling box 10 in the first direction defines a second groove 15. The second groove 15 can communicate with the liquid inlet channel 11 and the liquid outlet channel 12. At least part of the second end cover 30 is accommodated in the second groove 15, and the second end cover 30 is fixedly connected to the liquid cooling box 10.

[0054] It can be understood that the first end cover 20 can be completely located in the first groove 14, or one side can protrude from the first groove 14 along the first direction, and the embodiments of the present application are not limited to this. Similarly, the second end cover 30 can be completely located in the second groove 15, or one side can protrude from the second groove 15 along the second direction, and the embodiments of the present application are not limited to this.

[0055] In some embodiments, the liquid cooling device 103 may further include a liquid inlet joint 40 and a liquid outlet joint 50. The liquid inlet joint 40 and the liquid outlet joint 50 are both passed through the first end cover 20 and are fixedly connected to the first end cover 20. The liquid inlet joint 40 is in communication with the liquid inlet channel 11. The liquid outlet joint 50 is in communication with the liquid outlet channel 12.

[0056] It can be understood that the liquid inlet connector 40 and the liquid outlet connector 50 can be connected to a liquid supply system (not shown) through a pipeline. The liquid supply system can output the coolant and input the coolant into the liquid inlet channel 11 through the liquid inlet connector 40. The coolant in the liquid inlet channel 11 can flow into the liquid outlet channel 12 through the connecting groove 13. The coolant in the liquid outlet channel 12 can flow into the liquid supply system through the liquid outlet connector 50.

[0057] The heat generated by the moving part 102 can be transferred to the liquid cooling box 10, and the liquid cooling box 10 can transfer the heat to the coolant in the liquid inlet channel 11 and the liquid supply channel. After the coolant absorbs the heat, it can flow into the liquid supply system for cooling; and in the process of the coolant flowing back to the liquid supply system, the liquid supply system can continuously input the coolant that has not absorbed the heat into the liquid inlet channel 11 through the liquid inlet connector 40. In this way, the coolant can continuously enter the liquid cooling device 103, and the coolant can be removed from the liquid cooling device 103 after absorbing the heat, thereby taking the heat generated by the moving part 102 away from the flat motor 100, and achieving heat dissipation of the moving part 102.

[0058] In the embodiments of the present application, there is no specific limitation on the number of the inlet channel 11 and the outlet channel 12. For example, the number of the inlet channel 11 and the outlet channel 12 can both be one. For another example, the number of the outlet channel 12 and the inlet channel 11 can be one, and the number of the other channel can be multiple. For another example, the number of the inlet channel 11 and the outlet channel 12 can both be multiple.

[0059] It can be understood that the number of the inlet joints 40 is the same as the number of the inlet channels 11, and the number of the outlet joints 50 is the same as the number of the outlet channels 12. When there are multiple inlet channels 11 and multiple inlet joints 40, the multiple inlet joints 40 correspond to the multiple inlet channels 11. When there are multiple outlet channels 12 and multiple outlet joints 50, the multiple outlet joints 50 correspond to the multiple outlet channels 12.

[0060] In some embodiments, a plurality of mounting holes 16 may be provided on the liquid cooling box 10 , each mounting hole 16 may penetrate the liquid cooling box 10 along the third direction, and each mounting hole 16 is spaced apart from the liquid inlet channel 11 and the liquid outlet channel 12 .

[0061] It is understandable that each mounting hole 16 can accommodate a corresponding connector (not shown). The staff can pass the corresponding connector through the mounting hole 16 and then fix it on the movable member 102, and fix the connector to the liquid cooling box 10 to achieve a fixed connection between the liquid cooling box 10 and the movable member 102.

[0062] In the embodiment of the present application, there is no specific limitation on the connecting member penetrating the mounting hole 16. For example, the connecting member penetrating the mounting hole 16 can be, but is not limited to, a screw.

[0063] In some embodiments, a plurality of mounting grooves 17 may be provided on the liquid cooling box 10. The mounting grooves 17 are grooves, and the mounting grooves 17 extend along the third direction. Each mounting groove 17 is spaced apart from the liquid inlet channel 11, the liquid outlet channel 12 and the mounting hole 16.

[0064] It can be understood that each mounting groove 17 can accommodate a corresponding connecting piece (not shown). The staff can extend the connecting piece that passes through the slider (not shown) into the corresponding mounting groove 17, and realize the fixed connection between the corresponding connecting piece and the liquid cooling box 10 through the mounting groove 17, thereby realizing the fixed connection between the slider and the liquid cooling box 10 and the moving member 102. When the moving member 102 moves along the first direction, it can drive the slider to move synchronously along the first direction. A carrying mechanism such as a tray can be provided on the slider to carry the corresponding material. In this way, the flat motor 100 can realize the transmission of the material in the first direction.

[0065] In the embodiment of the present application, there is no specific limitation on the connecting member that enters the installation groove 17. For example, the connecting member that enters the installation groove 17 can be, but is not limited to, a screw. Exemplarily, the installation groove 17 can be a threaded groove, and the connecting member that extends into the installation groove 17 is a screw, and each connecting member can be threadedly connected to the corresponding installation groove 17.

[0066] The following describes in detail various arrangements of the liquid inlet channel 11 and the liquid outlet channel 12 when there are one or more liquid inlet channels 11 and the liquid outlet channels 12 .

[0067] Please also read FIG. 3A to FIG. 3C In the first case, the liquid inlet channel 11 and the liquid outlet channel 12 are spaced apart in the second direction and arranged in a row. At least one of the liquid inlet channel 11 and the liquid outlet channel 12 has one channel.

[0068] For example, Figure 3A As shown, the number of the inlet channel 11 and the outlet channel 12 are both one. The inlet channel 11 and the outlet channel 12 are arranged at intervals along the second direction. One end of the connecting groove 13 is connected to the inlet channel 11, and the other end is connected to the outlet channel 12.

[0069] For example, Figure 2B and Figure 3B As shown, the number of the inlet channel 11 can be one, and the number of the outlet channels 12 can be two. The inlet channel 11 can be located between the two outlet channels 12, and can be spaced apart from the two outlet channels 12 along the second direction. The number of the connecting grooves 13 can be equal to or greater than the number of the outlet channels 12, and each outlet channel 12 corresponds to at least one connecting groove 13. Each connecting groove 13 connects the corresponding outlet channel 12 and the only inlet channel 11.

[0070] In the embodiment of the present application, there is no specific limitation on the number of the communication grooves 13 corresponding to each liquid outlet channel 12. When each liquid outlet channel 12 corresponds to a plurality of communication grooves 13, the plurality of communication grooves 13 connected to the same liquid outlet channel 12 can be arranged at intervals in a direction perpendicular to the first direction.

[0071] For example, Figure 3C As shown, the number of the liquid outlet channel 12 can be one, and the number of the liquid inlet channel 11 can be two. The liquid outlet channel 12 can be located between the two liquid inlet channels 11, and can be spaced apart from the two liquid inlet channels 11 along the second direction. The number of the connecting grooves 13 can be equal to or greater than the number of the liquid inlet channels 11, and each liquid inlet channel 11 corresponds to at least one connecting groove 13. Each connecting groove 13 connects the corresponding liquid inlet channel 11 and the only liquid outlet channel 12.

[0072] In the embodiment of the present application, there is no specific limitation on the number of the communication grooves 13 corresponding to each liquid inlet channel 11. When each liquid inlet channel 11 corresponds to a plurality of communication grooves 13, the plurality of communication grooves 13 connected to the same liquid inlet channel 11 can be arranged at intervals in a direction perpendicular to the first direction.

[0073] Please also read FIG. 4A to FIG. 4C In the second case, the liquid inlet channel 11 and the liquid outlet channel 12 are spaced apart in the second direction and arranged in a row. The number of the liquid inlet channel 11 and the number of the liquid outlet channel 12 are both multiple.

[0074] For example, Figure 4A As shown, the number of the liquid outlet channels 12 and the liquid inlet channels 11 can be two. The two liquid outlet channels 12 are arranged at intervals along the second direction, and the two liquid inlet channels 11 are arranged at intervals along the second direction, and the two liquid inlet channels 11 are located between the two liquid outlet channels 12. The number of the connecting grooves 13 can be equal to or greater than two. Each connecting groove 13 can connect an inlet channel 11 and a liquid outlet channel 12 adjacent to the inlet channel 11.

[0075] For example, Figure 4B As shown, the number of the liquid outlet channels 12 and the liquid inlet channels 11 can be two. The two liquid outlet channels 12 are arranged at intervals along the second direction, and the two liquid inlet channels 11 are arranged at intervals along the second direction, and the two liquid outlet channels 12 are located between the two liquid inlet channels 11. The number of the connecting grooves 13 can be equal to or greater than two. Each connecting groove 13 can connect a liquid outlet channel 12 and a liquid inlet channel 11 adjacent to the liquid outlet channel 12.

[0076] For example, Figure 4CAs shown, the number of the liquid outlet channels 12 and the liquid inlet channels 11 can be equal to or greater than two. The two liquid outlet channels 12 are arranged at intervals along the second direction, and the two liquid inlet channels 11 are arranged at intervals along the second direction. At least one liquid inlet channel 11 is arranged between every two adjacent liquid outlet channels 12, and at least one liquid outlet channel 12 is arranged between every two adjacent liquid inlet channels 11. The number of the connecting grooves 13 can be equal to or greater than the number of the larger number of the liquid outlet channels 12 and the liquid inlet channels 11. Each connecting groove 13 can connect one liquid outlet channel 12 and one liquid inlet channel 11 adjacent to the liquid outlet channel 12.

[0077] It can be understood that when there is a liquid inlet channel 11 between two liquid outlet channels 12, the liquid inlet channel 11 can be connected to one of the two liquid outlet channels 12 through the connecting groove 13, or can be connected to both of the liquid outlet channels 12 through the connecting groove 13, and the embodiments of the present application do not limit this. Similarly, when there is a liquid outlet channel 12 between two liquid inlet channels 11, the liquid outlet channel 12 can be connected to one of the two liquid inlet channels 11 through the connecting groove 13, or can be connected to both of the liquid inlet channels 11 through the connecting groove 13, and the embodiments of the present application do not limit this.

[0078] It can be understood that when two liquid inlet channels 11 are adjacent, the two liquid inlet channels 11 are not connected, thereby reducing the situation where the cooling liquid that has received heat flows back between the adjacent liquid inlet channels 11 and cannot be output from the liquid cooling device 103. When two liquid outlet channels 12 are adjacent, the two liquid outlet channels 12 are not connected, thereby reducing the situation where the cooling liquid that has received heat flows back between the adjacent liquid outlet channels 12 and cannot be output from the liquid cooling device 103.

[0079] Please also read FIG. 5A to FIG. 5C In the third case, the liquid inlet channel 11 and the liquid outlet channel 12 are arranged in a row at intervals in the third direction. The number of at least one of the liquid inlet channel 11 and the liquid outlet channel 12 is one.

[0080] For example, Figure 5A As shown, the number of the inlet channel 11 and the outlet channel 12 are both one. The inlet channel 11 and the outlet channel 12 are arranged at intervals along the third direction. One end of the connecting groove 13 is connected to the inlet channel 11, and the other end is connected to the outlet channel 12.

[0081] It can be understood that when a liquid inlet channel 11 and a liquid outlet channel 12 are arranged at intervals along the third direction, the liquid inlet channel 11 can be located on the side of the liquid outlet channel 12 away from or toward the movable component 102, and the embodiments of the present application are not limited to this.

[0082] For example, Figure 5BAs shown, the number of the inlet channel 11 can be one, and the number of the outlet channels 12 can be two. The inlet channel 11 can be located between the two outlet channels 12, and can be spaced apart from the two outlet channels 12 along the third direction. The number of the connecting grooves 13 can be equal to or greater than the number of the outlet channels 12, and each outlet channel 12 corresponds to at least one connecting groove 13. Each connecting groove 13 connects the corresponding outlet channel 12 and the only inlet channel 11.

[0083] For example, Figure 5C As shown, the number of the liquid outlet channel 12 can be one, and the number of the liquid inlet channel 11 can be two. The liquid outlet channel 12 can be located between the two liquid inlet channels 11, and can be spaced apart from the two liquid inlet channels 11 along the third direction. The number of the connecting grooves 13 can be equal to or greater than the number of the liquid inlet channels 11, and each liquid inlet channel 11 corresponds to at least one connecting groove 13. Each connecting groove 13 connects the corresponding liquid inlet channel 11 and the only liquid outlet channel 12.

[0084] In the fourth case, the liquid inlet channel 11 and the liquid outlet channel 12 are arranged in a row at intervals in the third direction. The number of the liquid inlet channel 11 and the number of the liquid outlet channel 12 are both multiple.

[0085] It can be understood that the arrangement of the inlet channel 11 and the outlet channel 12 in the fourth case can be similar to the arrangement of the inlet channel 11 and the outlet channel 12 in the second case, and the difference between the two cases can only be the difference in the arrangement direction.

[0086] For example, the number of the liquid outlet channels 12 and the number of the liquid inlet channels 11 can both be two. The two liquid outlet channels 12 are spaced apart along the third direction, the two liquid inlet channels 11 are spaced apart along the third direction, and the two liquid inlet channels 11 are located between the two liquid outlet channels 12. The number of the connecting grooves 13 can be equal to or greater than two. Each connecting groove 13 can connect one liquid inlet channel 11 and one liquid outlet channel 12 adjacent to the liquid inlet channel 11.

[0087] For example, the number of the liquid outlet channels 12 and the number of the liquid inlet channels 11 can both be two.
