The same reference numerals as those in FIG. 1 denote the same components as those in FIG. 1, so that a detailed description thereof will be omitted and only differences from FIG. 1 will be described.

2 is a cross-sectional view showing a contamination purification unit of a lifting assembly for a rack-and-pinion drive robot according to the present invention.

As shown in the figure, the lift assembly 10 for a rack-and-pinion drive type robot according to the present invention has a configuration in which the pinion 28 of the drive portion 16 is engaged with the rack 20 of the lifting / lowering shaft portion 14 . The rollers 30 and 32 provided on the fixing brackets 34 and 36 of the driving unit 16 are also provided with a sealing belt 38 having the same blocking structure as that of the conventional one.

The pollution purification unit 50 includes an induction pipe 52 for sucking and transferring the contamination source S and a discharge pipe 52 for discharging the pollution source S through the induction pipe 52. [ And a filter unit 54 and a first blowing unit 56 that are provided in the induction pipe 52. [

2, the induction pipe 52 is installed in the case 22 of the driving unit 16 so as to collect and transport the contaminant S existing in the inside space C2. One end of the induction pipe 52 is provided with a collecting induction grill 58 having a trunk tube shape and is installed to be pulled out from the surface of the case 22 opposed to the guide groove 40. At this time, it is preferable that the collection induction grill 58 is disposed as close as possible to the position where the rack 20 and the pinion 28 are engaged with each other.

A filter unit 54 and a first blowing unit 56 are sequentially installed in the induction pipe 52. The filter unit 54 includes an oil filter 62 for collecting oil and a dust filter 60 for collecting dust. The first blowing means 56 is preferably composed of a motor 64 and a fan 66 that rotates by driving the motor 56.

Further, a configuration in which an intake fan 68 is further provided between the collecting induction grill 58 and the filter section 54 to further enhance the suction force as needed is also included in the technical scope of the present invention.

A discharge pipe 70 is connected to the other end of the induction pipe 52 corresponding to one end of the induction pipe 52 to which the collecting induction grill 58 is connected and a discharge port 72 Is disposed in the inner space (C2) of the seal belt (38) through the guide groove (40) through which the lifting shaft portion (14) passes. 3A, 3B and 4, the discharging portion 72 has a T-shaped structure, and discharge ports 74 are formed on the lower surfaces of the discharge portions 72 on both sides thereof.

The second blowing means 76 is preferably composed of a motor 80 and a fan 82 rotated by driving the motor 56. The filter portion 78 preferably uses a dust filter Do.

Hereinafter, the operation of the pollution control unit of the lift assembly for a rack-pinion drive type robot according to the present invention will be described.

First, when the driving unit 16 is moved up and down, contamination sources (for example, foreign matter, vapor, particles, oily foreign matter) due to contamination are generated as in the conventional case. And the contaminant S is present in the inner space C2.

At this time, a suction force is generated by the driving of the first blowing means 56 provided in the pollution purification unit 50, and the contamination source S existing in the inside space C2 is guided through the collection induction grille 58, The contamination source S sucked into the induction pipe 52 is conveyed along the induction pipe 52 and passes through the filter unit 54. [

The contamination source S is filtered by the oil filter 62 and the dust filter 60 while the contamination source S is passing through the filter unit 54, The air is sucked into the cleaned state.

The purified air is discharged through the discharge port 72 of the discharge pipe 70. At this time, the discharge port 72 is formed on both sides of the discharge portion 72 with the seal belt 38 as a center, And is discharged from both sides of the discharge port 38 toward the lower direction. (See Fig. 4)

That is, conventionally, the contamination source S existing in the inner space C2 leaks to the outside through the guide groove 40 of the lifting and lowering shaft portion 14, and the room as well as the room is contaminated by the contamination source S, When the contamination purification unit of the lift assembly for a rack-and-pinion drive type robot according to the present invention is used, the contamination source S and the air sucked in the inner space C2 are filtered and purified, The problem that has occurred in the past is solved.
