Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, in particular to a linear motor with high-efficiency heat dissipation. Background Technique

[0002] The linear motor is a widely used industrial device. Due to factors such as the heating of the motor mover coil and frictional heating, a large amount of heat is generated inside the linear motor during operation. For some high-precision semiconductor products, the thermal expansion of materials or equipment caused by the temperature rise of the linear motor will greatly affect the finished product accuracy of the products.

[0003] At present, the heat dissipation methods of linear motors include water cooling and air cooling. Compared with the air cooling device, the water cooling device has higher heat dissipation performance and lower volume occupancy rate. However, for some workpieces that cannot be in contact with water or have a high leakage damage rate of the water cooling device, the linear motor can only use air cooling for heat dissipation. The existing linear motors using air cooling cannot meet the heat dissipation requirements of the above-mentioned workpieces. Therefore, there is a need for a linear motor based on air cooling that can efficiently dissipate heat. Content of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a linear motor with high-efficiency heat dissipation, which uses air cooling for heat dissipation, has a compact structure and high safety.

[0005] Based on the above purpose, the utility model adopts the following technical solutions:

The motor stator is arranged on the base and extends along the front-back direction of the linear motor; the guide rail assembly includes two guide rails arranged on the left and right sides of the motor stator; the guide rails extend along the front-back direction of the linear motor; at least part of the motor mover is arranged inside the motor stator and can move along the front-back direction of the linear motor inside the motor stator; the connection assembly includes a mover connecting plate, a mover connecting seat and a slider; the slider is slidably arranged on the guide rail; the mover connecting plate is arranged on the slider; at least part of the mover connecting seat is arranged on the lower side of the mover connecting plate, the left end is connected to the motor mover, and the right end is provided with a first heat dissipation member; the first heat dissipation member extends along the front-back direction of the linear motor; a heat insulation plate is arranged between the mover connecting seat and the mover connecting plate.

[0007] Further, the linear motor further includes a second heat dissipation member; the second heat dissipation member is arranged at the left and right ends of the mover connecting plate and extends along the front-back direction of the linear motor.

[0008] Further, the linear motor further includes a third heat dissipation member; the third heat dissipation member is arranged at the left end of the motor stator and extends along the front-back direction of the linear motor.

[0009] The utility model provides a linear motor with high heat dissipation efficiency. The linear motor can dissipate heat from the mover connection seat by arranging a first heat dissipation member extending in the front-to-back direction on the mover connection seat; at the same time, a heat insulation plate is arranged between the mover connection seat and the mover connection plate to prevent heat from being transferred from the motor mover to the mover connection plate through the mover connection seat as much as possible, thereby preventing the mover connection plate from expanding and deforming, thereby affecting the processing accuracy of the material to be processed arranged on the mover connection plate. In addition, the first heat dissipation member can cooperate with the cold air conveying device arranged at the front / rear end of the linear motor to ensure that the heat dissipation requirements of the material to be processed are met.

[0010] Figure 1 It is a structural schematic diagram of a linear motor provided by the utility model. DETAILED DESCRIPTION

[0011] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0012] At the same time, in order to clearly explain the technical solution of this application, the following is also defined: Figure 1 Upper side, lower side, left side, right side, front side and back side shown.

[0013] like Figure 1 As shown, this embodiment provides a linear motor with high heat dissipation efficiency. The linear motor comprises: a base 11 , a motor stator 12 , a guide rail assembly 13 , a motor mover 14 and a connecting assembly 15 .

[0014] Specifically, the motor stator 12 is disposed on the base 11 and extends along the front-rear direction of the linear motor.

[0015] The guide rail assembly 13 includes two guide rails 131 disposed on the left and right sides of the motor stator 12. The guide rails 131 extend along the front-rear direction of the linear motor and are used to carry the connection assembly 15.

[0016] The motor mover 14 is at least partially disposed in the motor stator 12 and can move in the motor stator 12 along the front-rear direction of the linear motor.

[0017] The connecting assembly 15 is used to carry the motor mover 14 , and includes a mover connecting plate 151 , a mover connecting seat 152 and a slider 153 .

[0018] The slider 153 is slidably disposed on the guide rail 131 , and the connecting component 15 can slide on the guide rail 131 along the front-rear direction of the linear motor through the slider 153 .

[0019] The movable connecting plate 151 is mounted on the slider 153 and fixedly connected to the slider 153. Specifically, the top surface of the movable connecting plate 151 is substantially horizontally arranged to carry the material to be processed.

[0020] The mover connection seat 152 is at least partially disposed on the lower side of the mover connection plate 151, with the left end connected to the motor mover 14, and the right end provided with a first heat sink 16. The first heat sink 16 extends along the front-to-back direction of the linear motor. The first heat sink 16 can be configured as a heat sink fin, a heat sink slot, or other heat sinks for air cooling.

[0021] A heat insulation plate 17 is provided between the mover connecting plate 151 and the mover connecting seat 152 , and the mover connecting seat 152 is connected to the mover connecting plate 151 via the heat insulation plate 17 .

[0022] Through the above arrangement, the first heat sink 16 can dissipate heat from the mover connection seat 152 to prevent the heat generated by the motor mover 14 during operation from being transferred to the mover connection plate 151 through the mover connection seat 152, causing deformation of the mover connection plate 151 and affecting the processing accuracy of the material to be processed on the mover connection plate 151. At the same time, the heat insulation plate 17 can further reduce the heat transfer between the mover connection seat 152 and the mover connection plate 151. In addition, the first heat sink 16 can cooperate with the cold air delivery device arranged on the front or rear side of the linear motor to ensure that the heat dissipation capacity of the linear motor meets the heat dissipation requirements of the material to be processed.

[0023] More specifically, the linear motor further includes a second heat sink 18. The second heat sink 18 is installed at the left and right ends of the mover connecting plate 151 to further dissipate heat from the mover connecting plate 151 and reduce the possibility of deformation of the mover connecting plate 151. The second heat sink 18 extends along the front-to-back direction of the linear motor to cooperate with the cold air delivery device to improve the heat dissipation effect. Among them, the second heat sink 18 can be set as a heat sink fin, a heat sink or other heat sink for air cooling.

[0024] Furthermore, the linear motor also includes a third heat sink 19. The third heat sink 19 is installed at the left end of the motor stator 12, and is used to dissipate heat from the motor stator 12, so as to prevent the heat generated by the coil of the motor mover 14 from being transferred to the base 11 through the motor stator 12, causing deformation of the base 11. The third heat sink 19 extends along the front-to-back direction of the linear motor to cooperate with the cold air delivery device to improve the heat dissipation effect. Among them, the third heat sink 19 can be set as a heat sink fin, a heat sink or other heat sink for air cooling.

[0025] Furthermore, a heat dissipation channel or a heat insulation device may be provided between the base 11 and the motor stator 12 to further isolate the heat transfer between the base 11 and the motor stator 12 .

[0026] In summary, the present application provides a linear motor. The linear motor is provided with a first heat dissipation member 16, a second heat dissipation member 18, and a third heat dissipation member 19, which dissipate heat from the mover connection seat 152, the mover connection plate 151, and the motor stator 12 respectively, so as to prevent the equipment of the linear motor from deforming due to the heat generated during the operation of the linear motor, thereby affecting the processing accuracy of the material to be processed. At the same time, the first heat dissipation member 16, the second heat dissipation member 18, and the third heat dissipation member 19 can be cooperatively arranged with a cold air delivery device on the front side or the rear side of the linear motor to ensure that the linear motor meets the heat dissipation requirements of the material to be processed. In addition, the above linear motor has a compact structure, higher safety and applicability.
