[0052] Specifically, the extraction sleeve 1 is placed in the first feeding mechanism 9, and the extraction sleeve 1 is transported to the designated position through the loading track of the first feeding mechanism 9. The offset cylinder 62 is actuated to drive the dividing plate 63 to move left and right, and four extraction sleeves 1 are placed in the groove of the dividing plate 63. Then, the first upper and lower cylinders 65 move downward to drive the first extraction head 67 installed on the first extraction plate 66 to extend into the groove of the dividing plate 63. The first extraction head 67 generates a vacuum through the vacuum generator to suck the extraction sleeve 1. The first upper and lower cylinders 65 move upward. After reaching the designated position, the first front and rear cylinders 68 move backward, driving the first extraction plate 66 and the first extraction head 67 with the extraction sleeve 1 sucked to move together to the top of the tooling 791. The first upper and lower cylinders 65 move downward. When the extraction sleeve 1 is placed in the designated position of the tooling 791, the first extraction head 67 vacuum leaks. After the first upper and lower cylinders 65 move upward back to the designated position, the first front and rear cylinders 68 move forward to the original position to start the next material picking action.

[0053] It should be noted that the power motor drives the disc 5 on the divider to rotate, and the tooling 791 with the extraction sheath 1 installed is moved to the first assembly mechanism 7 .

The second upper and lower cylinder 75 is displaced in the horizontal direction by the extension and retraction of the output end of the second front and rear cylinder 78. A pushing cylinder 79 is also provided below the fixing frame 71, and a tooling 791 is installed on the top of the pushing cylinder 79.

[0055] Specifically, the extraction cap body 2 is placed in the second feeding mechanism 10, and the extraction cap body 2 is transported to a predetermined position through the loading track of the second feeding mechanism 10. The cross-cutting cylinder 72 drives the cross-cutting plate 73 to move left and right to extract four extraction cap bodies 2. The second upper and lower cylinders 75 drive the second extraction plate 76 installed on the connecting plate 74 to move downward. When the second extraction plate 76 is inserted into the extraction cap body 2, the second extraction plate 76 absorbs the extraction cap body 2 through the vacuum generating device. The second upper and lower cylinders 75 drive the second extraction head 77 installed on the connecting plate 74 to move upward, and the power motor drives the disc 5 on the divider to rotate. The tooling 791 with the extraction sheath 1 installed is moved to the first assembly mechanism 7.

[0056] It should be noted that the second front and rear cylinder 78 moves backward, and when it reaches the specified position above the tooling 791, the second upper and lower cylinder 75 drives the second extraction head 77 installed on the connecting plate 74 to move downward, and at the same time, the pushing cylinder 79 drives the tooling 791 to move upward. Under the action of the upper and lower forces, the extraction sheath 1 and the extraction cap body 2 are installed together. Then, the vacuum in the second extraction head 77 is destroyed, and the second upper and lower cylinder 75 drives the second extraction head 77 installed on the connecting plate 74 to move upward, and at the same time, the pushing cylinder 79 drives the tooling 791 to move downward. The second upper and lower cylinder 75 moves upward to the specified position, and the second front and rear cylinder 78 moves forward to the original position.

[0057] Then the disc 5 rotates, and the extraction cap body 2 and the extraction sheath 1 are assembled and moved to the second assembly mechanism 8, and the filter membrane 3 is transported to the designated position by the third feeding mechanism 11 of the second assembly mechanism 8.

[0058] See also Figure 3 , 8 -12, one end of the second assembly mechanism 8 is fixedly connected to the third feeding mechanism 11, and the third feeding mechanism 11 is provided with a filter membrane 3 inside, and the filter membrane 3 is transported to the second assembly mechanism 8 by the third feeding mechanism 11, so as to complete the installation of the filter membrane 3 in the extraction cap body 2, and the second assembly mechanism 8 comprises: a mounting frame 81 fixedly connected to the machine table 4, a cutting cylinder 82 is fixedly installed on one side of the mounting frame 81, and a pair of cutting plates 83 for cutting the filter membrane 3 transported by the third feeding mechanism 11 are fixedly connected to the output end of the cutting cylinder 82, and the mounting frame 81 is provided with a plurality of cutting plates 83 for cutting the filter membrane 3 transported by the third feeding mechanism 11. A third upper and lower cylinder 84 is also installed, and a suction cup manifold 85 is fixedly connected to the output end of the third upper and lower cylinder 84. The bottom of the suction cup manifold 85 is connected in sequence with multiple suction port connecting rods 86, and the bottom of each suction port connecting rod 86 is connected to a suction cup 87. One side of the third upper and lower cylinder 84 is also fixedly connected to the output end of the third front and rear cylinder 88. The third upper and lower cylinder 84 is moved horizontally on the mounting frame 81 through the third front and rear cylinder 88. Each suction cup 87 is threadedly connected to the suction port connecting rod 86, and a plurality of capillary holes 871 are provided at the bottom of the suction cup 87.

[0059] Specifically, the cutting plate 83 moves left and right under the drive of the cutting cylinder 82 to convert the four filter membranes 3 to the correct position, the third upper and lower cylinders 84 move downward, driving the suction cup manifold 85 and the suction cup 87 thereon to move downward, the suction cup 87 forms a certain vacuum through the suction cup manifold 85 to suck the filter membrane 3, the third upper and lower cylinders 84 move upward, suck the filter membrane 3 from the cutting plate 83, the third front and rear cylinders 88 move toward the disc 5, and when it reaches the specified position above the tooling 791, the third upper and lower cylinders 84 move downward until the filter membrane 3 is inserted into the specified position in the accommodating cavity 21, the suction cup manifold 85 breaks the vacuum, the third upper and lower cylinders 84 move upward, the suction cup 87 detaches from the filter membrane 3, and then the disc 5 rotates to the detection mechanism 12, and the presence or absence of the filter membrane 3 is detected by photoelectric detection, the disc 5 rotates again to the finished product conveying mechanism 13, and the qualified products and unqualified products are discharged respectively through the unloading cylinder 133.

[0060] It should be noted that, in this embodiment, the suction cup 87 is designed with a plurality of capillaries 871. Through experimental tests, it is found that this design effectively solves the current problem of automatic extraction of mesh objects.

[0061] In some embodiments, the suction cup 87 is fixed to the suction port connecting rod 86 by threads, and the bottom of the suction cup 87 is densely covered with tiny capillaries 871. The aperture of the capillary pores 871 is designed according to the grid of the mesh, and the minimum is 0.1 mm or even less than 0.1 mm. This design of capillary pores 871 has a small ventilation volume of each capillary pore 871. Even if some capillary pores 871 are not blocked by objects, it will not cause a large leakage to the vacuum degree, and can effectively absorb porous objects.

[0062] In other embodiments, the capillary holes 871 are not only circular, but can be any shape. The arrangement of the capillary holes 871 is not just in the schematic diagram, but can be arranged at will according to the shape of the suction cup 87.

[0063] See also Figure 3 , 13 -14, also includes: a detection mechanism 12 arranged around the outer side of the disc 5, wherein the detection mechanism 12 is used to detect the installed finished product, and the detection mechanism 12 includes: a bracket 121 fixedly connected to the machine table 4, a fourth upper and lower cylinder 122 is fixedly connected to the bracket 121, and a supporting plate 123 is fixedly installed on the output end of the fourth upper and lower cylinder 122, a plurality of detection columns 124 are penetrated on the supporting plate 123, a detection sheet 125 is fixedly connected to the top of the detection column 124, a spring 126 is sleeved and fixed on the outer wall of the detection column 124 between the detection sheet 125 and the supporting plate 123, and an optical fiber 127 is also arranged on one side of the supporting plate 123 corresponding to the plurality of detection columns 124.

[0064] Specifically, the detection mechanism 12 is fixed on the machine 4 by a bracket 121, the fourth upper and lower cylinder 122 is fixed on the bracket 121, the detection column 124 is fixed on the fourth upper and lower cylinder 122, a spring 126 is installed on the upper end of the detection column 124, a detection piece 125 is installed on the top of the spring 126, and the optical fiber 127 is also installed on the bearing plate 123 of the detection column 124. The product with the filter membrane 3 installed moves to the detection mechanism 12 as the disc 5 rotates. The product stays directly below the detection column 124, and the fourth upper and lower cylinder 122 moves downward, driving the detection column 124 to insert downward into the product cavity. When there is no filter membrane 3 in the product cavity, the optical fiber 127 cannot detect the detection piece 125, then The optical fiber 127 transmits a signal to the host PLC, and the PLC determines that the product is unqualified. When the filter membrane 3 in the product cavity is not installed in place, the detection column 124, driven by the fourth upper and lower cylinders 122, continues to push the filter membrane 3 downward to install the filter membrane 3 in the correct position. If the filter membrane 3 is installed in the correct position, the optical fiber 127 can just detect the detection piece 125, and the PLC determines that the product at this position is qualified. If the position of the filter membrane 3 is not reasonable for the first time, and the detection column 124 cannot install it in the correct position, the position of the detection piece 125 will be higher than the optical fiber 127, and the optical fiber 127 still cannot detect the detection piece 125, and the PLC still determines that the product here is unqualified.

[0065] See also Figure 3 , 15 -16, also includes: a finished product conveying mechanism 13, the finished product conveying mechanism 13 is used to select and convey qualified / unqualified products, the finished product conveying mechanism 13 includes: a connecting frame 131 fixedly connected to the machine platform 4, a fifth upper and lower cylinder 132 is fixedly connected to the connecting frame 131, a feeding cylinder 133 is fixedly connected to the output end of the fifth upper and lower cylinder 132, a fourth front and rear cylinder 134 is also provided on one side of the connecting frame 131, and the output end of the fourth front and rear cylinder 134 is fixedly connected to one side of the fifth upper and lower cylinder 132 to drive the horizontal movement of the fifth upper and lower cylinder 132, a finished product conveying channel 135 is provided at the bottom of the connecting frame 131, and a defective product conveying channel 136 is also provided in the finished product conveying channel 135, and a positioning cylinder 137 is symmetrically provided on one side of the fifth upper and lower cylinder 132 with the fourth front and rear cylinder 134, and the positioning cylinder 137 corresponds to the defective product conveying channel 136.

[0066] Specifically, the four unloading cylinders 133 act independently.

[0067] When the assembled product moves to the finished product conveying mechanism 13, the fifth upper and lower cylinder 132 installed on the connecting frame 131 moves downward, driving the unloading cylinder 133 installed thereon to move toward the extraction cap body 2 at the same time. When the unloading cylinder 133 reaches the specified position, the unloading cylinder 133 clamps the product under the action of compressed air, and the unloading cylinder 133 moves upward, and the fourth front and rear cylinder 134 installed on the connecting frame 131 moves forward. When there are unqualified products, the positioning cylinder 137 moves forward to position the fourth front and rear cylinder 134 for the first time above the defective product conveying channel 136, and the unloading cylinder 133 with the unqualified products releases its clamping jaws, puts down the unqualified products, and puts the unqualified products into the container through the defective product conveying channel 136.

[0068] After releasing the unqualified products, the positioning cylinder 137 moves backward, and the fourth front and rear cylinder 134 continues to move forward to the specified position of the finished product conveying channel 135. The unloading cylinder 133 holding the qualified products releases its clamping claws and puts down the qualified products. The fourth front and rear cylinder 134 drives the unloading cylinder 133 back to the starting position for the next action.

[0070] In this embodiment, the first feeding mechanism 9 , the second feeding mechanism 10 , and the third feeding mechanism 11 preferably use a vibration plate, which can effectively transport the extraction sheath 1 , the extraction cap body 2 , and the filter membrane 3 .

The filter membrane (3) is transported into the second assembly mechanism (8) by the third feeding mechanism (11), thereby completing the installation of the filter membrane (3) in the extraction cap body (2); A detection mechanism (12) and a finished product conveying mechanism (13) arranged around the outer side of the disc (5); Wherein, the detection mechanism (12) is used to detect the finished product after installation; The finished product conveying mechanism (13) is used to select and convey qualified products / unqualified products; The detection mechanism (12) is fixed on the machine platform (4) by a bracket (121), the fourth upper and lower cylinder (122) is fixed on the bracket (121), the detection column (124) is fixed on the fourth upper and lower cylinder (122), a spring (126) is installed on the upper end of the detection column (124), a detection sheet (125) is installed on the top of the spring (126), and the optical fiber (127) is also installed on the bearing plate (123) of the detection column (124). The product with the filter membrane (3) installed moves to the detection mechanism (12) as the disc (5) rotates, and the product stays directly below the detection column (124). The fourth upper and lower cylinder (122) moves downward, driving the detection column (124) to be inserted downward into the product cavity. When there is no filter membrane (3) in the product cavity, the optical fiber (127) cannot detect the detection sheet ( 125), the optical fiber (127) transmits a signal to the host PLC, and the PLC determines that the product is unqualified. When the filter membrane (3) in the product cavity is not installed in place, the detection column (124) continues to push the filter membrane (3) downward under the drive of the fourth upper and lower cylinders (122) to install the filter membrane (3) to the correct position. If the filter membrane (3) is installed in the correct position, the optical fiber (127) can just detect the detection sheet (125), and the PLC determines that the product at this position is qualified. If the position of the filter membrane (3) is not reasonable for the first time, the detection column (124) cannot install it to the correct position, and the position of the detection sheet (125) will be higher than the optical fiber (127). The optical fiber (127) still cannot detect the detection sheet (125), and the PLC still determines that the product here is unqualified.
