Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and in particular to a heat dissipation device for linear motors. Background Technology

[0002] Linear motors are widely used in precision manufacturing, semiconductor equipment, automated production lines, logistics sorting systems, and many other fields due to their advantages such as high precision, high response speed, and high acceleration. However, when linear motors operate under high-speed and high-load conditions, the linear motor coils generate a lot of heat. High temperatures not only reduce the efficiency and output of the motor and accelerate the aging of insulation materials, shortening its service life, but more seriously, they can cause irreversible demagnetization of the motor materials, directly affecting the motor's precision, reliability, and dynamic performance. Therefore, a linear motor heat dissipation device is needed to assist in cooling the linear motor.

[0003] Existing linear motors rely on natural convection heat exchange between the motor casing or heat sink fins and the ambient air for cooling. This method is simple, low-cost, and noiseless, but its heat dissipation capacity is extremely limited. Some methods that embed cooling pipes inside the motor and circulate coolant for cooling are complex in structure, expensive, have leakage risks, increase system weight, and make maintenance more difficult. Using cooling fans for cooling can easily lead to "short circuits" or "dead zones" in airflow inside or on the surface of the motor. In areas far from the fan, especially at both ends of the motor, the airflow speed is slow or even stagnant, resulting in poor heat dissipation and the formation of localized hot spots. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a linear motor heat dissipation device, which more precisely solves the problems of poor heat dissipation efficiency, complex structure, and incomplete heat dissipation in existing linear motors.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a heat dissipation device for a linear motor, including a first end plate, a second end plate symmetrically arranged on one side of the first end plate, and a heat dissipation component arranged between the first end plate and the second end plate. The heat dissipation component is used to dissipate heat and cool down the linear motor coil.

[0007] Furthermore, the heat dissipation assembly includes a mounting base, which is bolted to the top of the first end plate and the second end plate. Anti-collision devices are installed on the side walls of both the first end plate and the second end plate. A drag chain is provided on the top of the mounting base, and two sets of photoelectric sensors are symmetrically installed on the top of the mounting base.

[0008] Furthermore, a linear motor magnetic plate is installed on the side wall of the fixed base, and two sets of guide rails are installed on the side wall of the fixed base by bolts. A slider is slidably installed on the outside of the guide rails, and a motor mounting plate is installed on the side wall of the slider by bolts.

[0009] Furthermore, the two sets of guide rails are located at the top and bottom of the linear motor magnetic plate, and multiple through openings are formed on the surface of the motor mounting plate.

[0010] Furthermore, a linear motor coil is bolted to the side wall of the motor mounting plate, an encoder is bolted to the top of the side wall of the motor mounting plate, and two sets of cooling fans are embedded in the motor mounting plate.

[0011] Furthermore, the linear motor coil is correspondingly arranged with the linear motor magnetic plate, the encoder is located between the two sets of photoelectric sensors, and the cooling fan is located on one side of the linear motor coil.

[0012] Furthermore, two sets of air intake pipe connectors are symmetrically installed on the top of the motor mounting plate, a flow channel is opened inside the motor mounting plate, and multiple sets of exhaust ports are symmetrically opened on the side wall surface of the motor mounting plate.

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0024] Please refer to Figures 1-5 This utility model proposes a heat dissipation device for a linear motor, including a first end plate 1, a second end plate 2 symmetrically arranged on one side of the first end plate 1, and a heat dissipation assembly between the first end plate 1 and the second end plate 2. The heat dissipation assembly is used to dissipate heat and cool down the linear motor coil 10.

[0025] The heat dissipation assembly includes a mounting base 3, which is bolted to the top of the first end plate 1 and the second end plate 2. Anti-collision devices 16 are installed on the side walls of both the first end plate 1 and the second end plate 2 to limit the movement range of the linear motor. A drag chain 4 is provided on the top of the mounting base 3 for laying the linear motor's wiring or piping. Two sets of photoelectric sensors 5 are symmetrically installed on the top of the mounting base 3 to limit the movement range of the motor mounting plate 9. A linear motor magnetic plate 6 is installed on the side wall of the mounting base 3 to generate magnetic attraction, causing the linear motor to generate thrust. Two sets of guide rails 7 are bolted to the side wall of the mounting base 3 to limit the movement of the slider 8. The slider 8 is slidably mounted on the outside of the guide rails 7. A motor mounting plate 9 is bolted to the side wall of the slider 8 for mounting and fixing the linear motor coil 10 and the cooling fan 12. The two sets of guide rails 7 are located at the top and bottom of the linear motor magnetic plate 6. Multiple through-holes are opened on the surface of the motor mounting plate 9 to ensure heat dissipation of the linear motor coil 10.

[0026] A linear motor coil 10 is bolted to the side wall of the motor mounting plate 9 to convert electrical energy into mechanical energy and achieve linear motion. An encoder 11 is bolted to the top of the side wall of the motor mounting plate 9 to record and provide feedback on the position of the linear motor coil 10. Two sets of cooling fans 12 are embedded in the motor mounting plate 9 to dissipate heat from the linear motor coil 10. The linear motor coil 10 is correspondingly arranged with the linear motor magnetic plate 6. The encoder 11 is located between the two sets of photoelectric sensors 5, and the cooling fan 12 is located on one side of the linear motor coil 10.

[0027] Two sets of air inlet pipe connectors 13 are symmetrically installed on the top of the motor mounting plate 9 for connecting to air pipes. A flow channel 14 is provided inside the motor mounting plate 9 for gas flow. Multiple sets of exhaust ports 15 are symmetrically provided on the sidewall surface of the motor mounting plate 9 for heat dissipation. The flow channel 14 is connected to the air inlet pipe connectors 13 and the exhaust ports 15. The edges of the multiple sets of exhaust ports 15 are chamfered. The multiple sets of exhaust ports 15 are located on both sides of the cooling fan 12. In the initial state, the air pipe and the air inlet pipe connectors... Connected together, compressed air enters the flow channel 14 through the air inlet pipe connector 13 and is finally discharged through the exhaust port 15. With the cooperation of the cooling fan 12, the linear motor coil 10 can be cooled down. With the chamfered arrangement of multiple exhaust ports 15, the direct cooling area is expanded, the coverage is increased, the blind area that the cooling fan 12 cannot reach is covered, the air intake volume is increased, the air flow rate is accelerated, and the air circulation is accelerated, achieving a good and efficient cooling effect and ensuring the stable operation of the linear motor.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
