[0030] Referring to the attached Figures 1-5 , an automatic material embedding device for a filter screen injection molding manipulator in this embodiment includes a manipulator 1 and a tooling fixture detachably installed on the manipulator 1. The tooling fixture includes a bottom plate 2, and a fixing plate 3 is correspondingly installed on one side of the bottom plate 2. A sleeve pipe 11 is correspondingly installed at the corresponding position on the fixing plate 3. The sleeve pipe 11 is formed by surrounding and closing two semi-circular pipe fittings, and the gap at the outer end of the two semi-circular pipe fittings is larger than the gap at the inner end. A driven and telescopic push plate 10 is also correspondingly provided on the side of the fixing plate 3. A round hole 1001 matching the sleeve pipe 11 is provided on the push plate 10, and the sleeve pipe 11 correspondingly slides through the round hole 1001 on the push plate 10. The annular cylindrical mesh cloth on the sleeve pipe 11 is embedded into the corresponding mold cavity through the push plate 10. A plurality of flexible clamping jaws 5 capable of telescopic movement are also correspondingly provided on one side of the fixing plate 3. The number and position of the flexible clamping jaws 5 are horizontally corresponding to the number and position of the sleeve pipes 11 on the fixing plate 3. The injection-molded filter screen can be taken out through the flexible clamping jaws 5.

[0031] Specifically, an arc transition section 1101 with a diameter shrinking inward is correspondingly provided at the outer end of the nesting tube 11, which facilitates feeding by sleeving the annular cylindrical mesh cloth on the nesting tube 11.

[0032] The four sides of the fixed plate 3 are correspondingly installed on the bottom plate 2 through the connecting rods 7. A movable plate 6 is correspondingly provided between the fixed plate 3 and the bottom plate 2. One side of the movable plate 6 is correspondingly installed with a cylinder 4, and the cylinder 4 is fixedly installed on the bottom plate 2 correspondingly; both ends of one side surface of the pushing plate 10 are correspondingly installed with connecting plates 8. The fixed plate 3 is correspondingly provided with through holes 301 for the connecting plates 8 to penetrate through.

Since the nesting tube 11 is formed by surrounding and closing two semi-circular pipe fittings, and the gap at the outer end of the two semi-circular pipe fittings is larger than the gap at the inner end, the nesting tube 11 will automatically unfold and clamp the annular cylindrical mesh cloth to prevent it from falling. At this time, the manipulator 1 is controlled to move to the corresponding mold cavity of the machine tool, and the annular cylindrical mesh cloth is pushed by the cylinder 4, so that the annular cylindrical mesh cloth can be automatically buried in the mold cavity.

A positioning short shaft 203 is correspondingly provided at the diagonal position in the mounting groove 201, and a positioning hole 103 that plugs and cooperates with the positioning short shaft 203 is provided at the corresponding position on the mounting plate 101, so that the installation and positioning are more accurate. Threaded rods 204 are correspondingly provided around the mounting groove 201 on the base plate 2, and a strip pressure block 205 is threadedly installed on the threaded rod 204. When installing, the strip pressure block 205 can be moved to press the mounting plate 101 against the mounting groove 201 to achieve installation.
