[0025] Refer to Figure 1 、 Figure 2, A liquid injection machine adsorption base, comprising a base body 1, a top rod assembly 2, a spring 3 and a suction cup 4. The top rod assembly 2, the spring 3 and the suction cup 4 are installed inside the base body 1. The spring 3 is arranged at the lower end of the top rod assembly 2, and the suction cup 4 is arranged at the upper end of the top rod assembly 2. At the same time, an air source connector 5 is externally connected to the top rod assembly 2, and the air source connector 5 is communicated with the suction cup 4. During operation, when the wiping paper tape falls onto the adsorption base, compressed air is introduced into the air source connector 5 to make the suction cup 4 generate suction force to adsorb the wiping paper tape. When the manipulator grabs the wiping paper tape, the suction cup 4 and the top rod assembly 2 are pressed downwards. The downward pressure of the top rod assembly 2 causes the spring 3 to contract, so that both ends of the wiping paper tape are lifted up to facilitate the clamping of the manipulator's jaws, enabling the manipulator to accurately grasp the wiping paper tape and ensuring the normal wiping work.

[0026] In addition, the suction cup 4 can adopt a Bernoulli suction cup, which generates suction force by using compressed air, or a self-made honeycomb hole suction cup, which generates suction force by using negative pressure vacuum, in order to adsorb the wiping paper tape. In addition, the air source connector 5 is equipped with a pressure regulating valve to adjust the air pressure according to different wiping paper tape materials, so as to ensure that the suction cup 4 has an appropriate adsorption force.

[0027] Refer to Figure 2 , Figure 3 , Figure 4 , In the embodiment of the present utility model, the base body 1 is provided with an installation cavity 11, so that the top rod assembly 2, the spring 3 and the suction cup 4 are installed in the installation cavity 11. At the same time, a limiting block 12 is arranged on the side wall of the installation cavity 11, and the top rod assembly 2 is arranged below the limiting block 12 to prevent the top rod assembly 2 from popping out of the base under the elastic force of the spring 3.

[0028] Specifically, a plurality of clamping notches 13 are arranged at the upper end of the installation cavity 11, and the plurality of clamping notches 13 are located on the side of the suction cup 4. Since the base body 1 in this embodiment is set as a square body structure, a clamping notch 13 is arranged on each of the four sides of the base body 1 to avoid the manipulator's jaws and facilitate the manipulator to grab the wiping paper tape. At the same time, it can also prevent the manipulator from grasping the base body 1 and causing friction and chip removal. In addition, an installation position 16 is arranged at the upper end of the base body 1, and a side sealing plate 6 is arranged on the installation position 16. The side sealing plate 6 is arranged at the outer end of the clamping notch 13. When the manipulator grabs the wiping paper tape, the wiping paper tape is pressed downwards along with the manipulator, and the side sealing plate 6 pushes up both sides of the wiping paper tape to facilitate the accurate clamping of the manipulator.

[0029] In addition, a stop block 14 is provided at the lower end of the base body 1. The stop block 14 is snap-fitted into the installation cavity 11 to limit the ejector rod assembly 2 and the spring 3 installed in the base body 1. Fixing blocks 15 are further provided at both ends of the base body 1. An installation hole 151 is provided on the fixing block 15, and fixing screws are used to pass through the installation hole 151 for fixed installation.

The air flow channel 211 is provided with an inlet 212 and an outlet 213. The air source connector 5 and the second ejector rod 22 are respectively hermetically connected to the inlet 212 and the outlet 213. A ventilation hole 221 is also provided in the middle of the second ejector rod 22. One end of the ventilation hole 221 communicates with the air flow channel 211, and the other end of the ventilation hole 221 communicates with the suction cup 4, so that the suction cup 4 is connected to the air source connector 5 to enable the suction cup 4 to generate suction force to adsorb the wiping paper tape.

[0031] In addition, a fastener 222 is provided at the upper end of the second ejector rod 22. The suction cup 4 is fixedly connected to the second ejector rod 22 through the fastener 222 for installation and fixation of the suction cup 4.
