[0022] Reference Figures 1 to 3 The fork arm structure shown in the figure includes a hollow mounting tube 11, a fixed sleeve 12 and a fork arm 13. The hollow mounting tube 11 is fixedly mounted at the output end of the robot 10, and the upper and lower ends of the hollow mounting tube 11 are connected. The fixed sleeve 12 is detachably sleeved on the lower end of the hollow mounting tube 11, and the fork arm 13 is fixedly connected to the lower end of the fixed sleeve 12. In this embodiment, the fixed sleeve 12 and the fork arm 13 can be removed or replaced from the hollow mounting tube 11 as a whole. During installation, it is only necessary to debug the installation accuracy between the hollow mounting tube 11 and the fixed sleeve 12 to ensure the accuracy of the fork arm 13. It is convenient and quick. The lower end of the fixed sleeve 12 is provided with a connector 1 21. The end of the fork arm 13 is provided with a suction hole 132 for sucking and fixing the product, and an air flow channel 131 is also provided inside the fork arm 13. One end of the air flow channel 131 is connected to the connector 121, and the other end is connected to the suction hole 132. The external air pipe 101 passes through the hollow mounting tube 11 from top to bottom and is connected to the connector 121. The fork arm structure of the utility model can hide the air pipe 101 in the hollow mounting tube 11 and the fixing sleeve 12, which can effectively avoid the problem of the air pipe 101 being worn or even broken due to scratching or interference with the external mechanism during use, and can also maintain the beauty between the robot 10 and the fork arm structure.

[0023] In some possible embodiments, reference Figure 3As shown, a first positioning pin hole 122 and a first locking hole 123 are provided on the side of the fixing sleeve 12, a positioning groove 111 is provided at a position corresponding to the first positioning pin hole 122 on the outer surface of the hollow mounting tube 11, and a locking plane 112 is formed at a position corresponding to the first locking hole 123 on the outer surface of the hollow mounting tube 11. When the fixing sleeve 12 is sleeved on the hollow mounting tube 11, the fixing sleeve 12 is first inserted and rotated to the position corresponding to the first positioning pin hole 122 and the positioning groove 111, and then the fixing sleeve 12 is inserted into the first positioning pin hole 122. Insert the positioning pin, and the first locking hole 123 also corresponds to the locking plane 112. In this embodiment, the first locking hole 123 can be a threaded hole. Screw the locking bolt into the first locking hole 123 and crimp the end of the locking bolt into the locking plane 112, so that the fixing sleeve 12 can be fixedly connected to the hollow mounting tube 11. In this embodiment, the fixing sleeve 12 and the hollow mounting tube 11 are easy to disassemble and assemble, and the positioning pin hole cooperates with the first locking hole 123 to ensure the positioning accuracy between the fixing sleeve 12 and the hollow mounting tube 11.

[0024] In some possible embodiments, reference Figure 2 and Figure 3 As shown, the upper end of the connector 121 is provided with a barb 124 that can be fixedly connected to the trachea 101. The barb 124 is annular and has at least two formed on the outer surface of the connector 121. The trachea 101 is sleeved on the upper end of the connector 121 and is fixed and sealed to the connector 121 through the barb 124. A sealing ring can be further provided between the two barbs 124 to further improve the sealing between the trachea 101 and the connector 121. A sealing ring 125 is provided at the lower end of the connector 121. The fork arm 13 is installed at the lower end of the fixed sleeve 12 and presses the sealing ring 125 to ensure the sealing between the airflow channel 131 and the connector 121.

[0025] In some possible embodiments, reference Figure 1 and Figure 3 As shown, an installation window 126 is provided on the side of the fixed sleeve 12 corresponding to the connecting head 121. The purpose is that after the fixed sleeve 12 is fixedly connected to the hollow mounting tube 11, the staff can easily connect the air pipe 101 to the upper end of the connecting head 121. Of course, it is also convenient to separate the air pipe 101 from the connecting head 121 first, and then remove the fixed sleeve 12 for easy disassembly / replacement.

[0026] In some possible embodiments, reference Figure 2 and Figure 3As shown, the suction holes 132 are distributed at the corners of the fork arm 13 and are located on the upper end surface of the fork arm 13. When in use, another robot can be used to place the product on the upper end surface of the fork arm 13 corresponding to the suction holes 132, and the lower end surface of the product covers the suction holes 132. The air pipe 101 inhales air and generates negative pressure at the suction holes 132, so that the product is firmly placed on the upper end surface of the fork arm 13 to ensure that the product will not fall from the fork arm 13 during the feeding process.

[0027] In some possible embodiments, reference Figures 1 to 3 As shown, a positioning column 133 is also provided on the fork arm 13 near the suction hole 132 , and the positioning column 133 is used to position the product on the fork arm 13 to ensure that the lower end surface of the product can completely cover the suction hole 132 .

[0028] In some possible embodiments, the fork arm 13 is flat and has an air flow groove formed on its lower surface. A sealing plate 134 is also provided on the lower surface of the fork arm 13 to seal the air flow groove to form an air flow channel 131. In this embodiment, the outer dimensions of the sealing plate 134 are equal to those of the fork arm 13. The sealing plate 134 can be fixed to the lower end surface of the fork arm 13 by sealing and bonding. Specifically, the fork arm 13 can be made of hard metal material, and the air flow groove and the suction hole 132 can be milled on its lower surface, and then the sealing plate 134 is sealed and fixed to the lower surface of the fork arm 13.

[0029] In some possible embodiments, the lower end surface of the fixed sleeve 12 is closed and a mounting hole is opened at the center of the lower end surface. The sealing ring 125 is arranged at the lower end of the mounting hole. Two second positioning pin holes and two second locking holes are evenly distributed in the circumference of the mounting hole. The fork arm 13 approaches the fixed sleeve 12 from bottom to top and passes through the second positioning pin hole through the positioning pin. Finally, the locking bolt is screwed into the second locking hole to fix the fork arm 13 to the fixed sleeve 12.
