[0036] Specifically, from the figure Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 Provided is a robot bidirectional fork arm 1 and a protection component 2 for sealing and protecting the robot bidirectional fork arm 1, wherein the protection component 2 comprises a protection shell 201 installed on the outside of the robot bidirectional fork arm 1, a slide groove 202 is provided on the front side of the protection shell 201, a guide groove 203 is provided on the inner wall of the slide groove 202, a square blocking plate 204 and two folding curtains 205 for sealing the slide groove 202 are slidably connected between the inner left wall and the inner right wall of the guide groove 203, wherein one folding curtain 205 is installed between the inner top wall of the guide groove 203 and the top of the square blocking plate 204, and the other folding curtain 205 is installed between the inner bottom wall of the guide groove 203 and the bottom of the square blocking plate 204, and the middle part of the square blocking plate 204 is rotatably connected with a circular blocking plate 206 plugged into the robot bidirectional fork arm 1;

[0037] A plurality of embedding grooves are provided on both sides of the left side of the square blocking plate 204, and the distance between two adjacent embedding grooves is equal. A ball 5 is embedded in the embedding groove. The material of the ball 5 is stainless steel, which is not easy to rust, thereby extending the service life of the ball 5. The inside of the ball 5 is integrally formed with a cavity, so that the weight of the ball 5 is light, avoiding affecting the rise or fall of the square blocking plate 204. The outer wall of the ball 5 is rollingly connected to the inner wall of the embedding groove, and the inner wall of the guide groove 203 is connected to the outer wall of the ball 5. Rolling connection, by setting the embedding groove, it is convenient to embed the ball 5 on the left and right sides of the square blocking plate 204. By setting the ball 5, the friction between the square blocking plate 204 and the guide groove 203 is reduced, ensuring that the square blocking plate 204 slides more smoothly in the guide groove 203. The left and right sides of the folding curtain 205 are equipped with multiple permanent magnetic sheets 6 that are magnetically attracted to the inner side wall of the guide groove 203. The two adjacent permanent magnetic sheets 6 are respectively located on both sides of the bending part of the folding curtain 205. The opposite ends of the two permanent magnetic sheets 6 are integrally formed with arc chamfers 7. By setting and utilizing the magnetism of the permanent magnetic sheets 6, the left and right sides of the folding curtain 205 are prevented from being away from the inner wall of the guide groove 203, thereby ensuring the sealing effect of the folding curtain 205. By setting the arc chamfers 7, the problem of motion interference caused by the permanent magnetic sheets 6 following the bending of the folding curtain 205 during movement is avoided. During the process of the robot's two-way fork arm 1 rising or falling in the protective shell 201, the square blocking plate 204 drives the two folding curtains 205 to fold or stretch in the guide groove 203, thereby sealing the slide groove 202 without affecting the up and down movement of the robot's two-way fork arm 1. By setting a circular blocking plate 206 rotatably connected to the square blocking plate 204, the rotation of the robot's two-way fork arm 1 is not affected during the sealing process, thereby ensuring the normal use of the robot's two-way fork arm 1, thereby blocking dust and oil molecules, preventing oil molecules from leaking out, and preventing dust from entering the robot's two-way fork arm 1, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot. Example

[0038] Furthermore, as a specific implementation of the present invention, the present invention provides a wafer box transporting composite robot.

[0039] Based on the first embodiment, specifically, Figure 5 and Figure 8The invention also includes a photovoltaic cell panel 3, which includes a slot 301 extending through the front side of the circular baffle plate 206 and a permanent magnetic limit ring 302 connected to the outer ring of the circular baffle plate 206. The slot 301 is plugged into the robot bidirectional fork arm 1. A rotating groove 303 rotatably connected to the outer ring of the circular baffle plate 206 is provided through the front side of the square baffle plate 204. An annular limit groove 304 is provided on the inner wall of the rotating groove 303. The permanent magnetic limit ring 302 is located inside the annular limit groove 304. The outer wall of the permanent magnetic limit ring 302 is rotatably connected to the inner wall of the annular limit groove 304. The outer surface is smooth and made of quartz glass with strong thermal stability. At the same time, the ring is embedded in the magnetic annular limit groove 304. The magnetic seal has a long service life. An extremely thin oil film is maintained between the sealing end faces to avoid dry friction between the end faces, and the circular baffle plate 206 cannot be separated from the square baffle plate 204 during the rotation of the robot's bidirectional fork arm 1. Without affecting the normal use of the robot's bidirectional fork arm 1, the fork arm joint rotates in a static sealing state to avoid leakage of oil molecules and dust from entering the robot's bidirectional fork arm 1, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot.

[0040] Furthermore, a sealing ring 4 is installed on the inner wall of the slot 301, and the outer wall of the sealing ring 4 is in conflict with the outer wall of the robot's bidirectional fork arm 1. The sealing ring 4 is made of nitrile rubber. Nitrile rubber has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. In addition, it also has good water resistance, air tightness and excellent bonding properties. By setting the sealing ring 4 to be made of nitrile rubber, the sealing between the slot 301 and the robot's bidirectional fork arm 1 is improved, blocking dust and oil molecules, preventing oil molecules from leaking, and preventing dust from entering the robot's bidirectional fork arm 1, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot.

[0041] Furthermore, an annular sealing gasket is installed on the inner wall of the rotating groove 303. The material of the annular sealing gasket is fluororubber. Fluororubber is a high-performance special rubber with excellent high temperature resistance and chemical stability. It is an ideal material for making seals in high temperature and high pressure environments. The outer ring of the circular baffle plate 206 is rotatably connected to the inner wall of the annular sealing gasket. By setting the annular sealing gasket to fluororubber material, the sealing between the rotating groove 303 and the circular baffle plate 206 is improved, dust and oil molecules are blocked, oil molecules are prevented from leaking, dust is prevented from entering the protective shell 201, and the cleanliness and service life of the fork arm of the stacking industrial robot are extended.

[0042] Working principle:

[0043] When the robot's bidirectional fork arm 1 rises or falls in the protective shell 201, the square blocking plate 204 drives the two folding curtains 205 to fold or stretch in the guide groove 203, thereby sealing the slide groove 202 without affecting the up and down movement of the robot's bidirectional fork arm 1. By setting a circular blocking plate 206 rotatably connected to the square blocking plate 204, the rotation of the robot's bidirectional fork arm 1 is not affected during the sealing process, ensuring the normal use of the robot's bidirectional fork arm 1, thereby blocking dust and oil molecules, preventing oil molecules from leaking, and preventing dust from entering the robot's bidirectional fork arm 1, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot.

[0044] The outer surface of the permanent magnetic limit ring 302 is smooth, and its material is quartz glass with strong thermal stability. At the same time, the ring is embedded in the magnetic annular limit groove 304. The magnetic seal has a long service life. An extremely thin oil film is maintained between the sealing end faces to avoid dry friction between the end faces, and the circular baffle plate 206 cannot be separated from the square baffle plate 204 during the rotation of the robot's bidirectional fork arm 1. Without affecting the normal use of the robot's bidirectional fork arm 1, the fork arm joint rotates in a static sealing state to avoid leakage of oil molecules and dust from entering the robot's bidirectional fork arm 1, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot.

[0045] By setting and utilizing the magnetism of the permanent magnetic sheet 6, the left and right sides of the folding curtain 205 are prevented from being away from the inner wall of the guide groove 203, thereby ensuring the sealing effect of the folding curtain 205. By setting the arc chamfer 7, the problem of motion interference caused by the permanent magnetic sheet 6 following the bending of the folding curtain 205 during movement is avoided. By setting the annular sealing gasket made of fluororubber material, the sealing between the rotating groove 303 and the circular blocking plate 206 is improved, dust and oil molecules are blocked, oil molecules are prevented from leaking, and dust is prevented from entering the protective shell 201, thereby extending the cleanliness and service life of the fork arm of the stacking industrial robot.
