[0024] Example 1:
[0025] Please see Figures 1-5 The present invention discloses a heat dissipation structure for a linear motor mover, comprising a mover slide rail 1, wherein a mover seat 2 is slidably mounted in the inner groove at the top of the mover slide rail 1.
[0026] A heat dissipation device 3 is provided on the left side of the moving base 2, and a ventilation device 4 is provided on the top right end of the moving base 2. The heat dissipation device 3 includes T-shaped plates 31 fixed to the lower ends of the left and right sides of the moving base 2 by screws. A temperature sensor 32 is provided on the left end of the rear face of the moving base 2. A brush strip 33 is glued to the bottom of the T-shaped plate 31. The moving brush strip 33 sweeps the dust or debris in the inner groove of the moving slide rail 1 to both sides to prevent it from obstructing the movement of the moving base 2.
[0027] A fan blade 34 is rotatably mounted on the upper left side of the moving base 2. An electric motor 35 is mounted on the upper left side of the moving base 2 by screws. The drive shaft on the left side of the electric motor 35 is connected to the right side of the fan blade 34 by a connecting rod. The electric motor 35 drives the fan blade 34 to rotate through the connecting rod. The T-shaped plate 31 is slidably connected to the inner groove at the top of the moving slide rail 1. There are two temperature sensors 32, which are respectively located on the upper left and right sides of the rear end face of the moving base 2. The temperature sensors 32 can detect the temperature inside the moving base 2 and improve the accuracy of the detection results. The outer surface of the T-shaped plate 31 is coated with a wear-resistant coating to reduce the wear generated by the T-shaped plate 31 during operation.
[0028] The working principle of the heat dissipation structure for a linear motor actuator based on Embodiment 1 is as follows:
[0029] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.
[0030] Secondly, the temperature sensor 32 can detect the temperature inside the moving base 2. When the temperature is too high, the control terminal controls the start of the electric motor 35. The electric motor 35 drives the fan blade 34 to rotate through the connecting rod, and then the fan blade 34 forms an airflow to carry away the heat inside the moving base 2.
[0031] Third, the moving movable seat 2 will drive the T-shaped plate 31 and the brush strip 33 to move. The moving brush strip 33 will sweep the dust or debris in the inner groove of the movable slide rail 1 to both sides to prevent it from obstructing the movement of the movable seat 2.
[0032] Fourth, by driving the fan blades 34 to rotate, airflow is generated to carry away the heat inside the moving base 2 for heat dissipation. The temperature sensor 32 detects the temperature inside the moving base 2, and the moving brush strips 33 sweep the dust or debris in the inner groove of the moving slide rail 1 to both sides to avoid obstructing the movement of the moving base 2.

[0035] In this embodiment:
[0036] After the control terminal receives the signal, the user first pulls out the limit bar 45 using the pull rod 44, and then pulls the push block 42 by hand to move the cover plate 41. At this time, the slot at the top right end of the moving base 2 opens. When the cover plate 41 can no longer move, the limit bar 45 is inserted into the cover plate 41 again using the pull rod 44. It is then attracted to the rear end of the moving base 2 by the magnet 43. At this time, the fixation of the cover plate 41 is completed. The filter screen 46 can filter impurities inside the outside air to prevent them from affecting the operation of the internal components of the moving base 2. This facilitates the contact and exchange between the inside of the moving base 2 and the outside air, helps to enhance the heat dissipation effect of the device, and the filter screen 46 can filter impurities inside the outside air to prevent impurities from entering and affecting the operation of the internal components.
[0037] This utility model provides an improved heat dissipation structure for the mover of a linear motor. A heat dissipation device 3 is installed on the left side of the mover base 2. Airflow is generated by fan blades 34 to carry away the heat inside the mover base 2. The fan blades 34 are driven to rotate to generate airflow and dissipate heat from the inside of the mover base 2. The temperature inside the mover base 2 is detected by a temperature sensor 32. A moving brush strip 33 sweeps away dust or debris in the inner groove of the mover slide rail 1 to both sides to avoid obstructing the movement of the mover base 2.
