DETAILED DESCRIPTION OF THE EMBODIMENT

[0019] The utility model will be further described in conjunction with the drawings and embodiments.

[0020] As Figures 1 to 3 shown, a battery air filter assembly mechanism described in the utility model includes a slide block guide rail 17 installed on a bottom plate 14, three picking and placing mechanisms installed on the slide block guide rail 17 for picking and placing an air filter 1, a ball screw stepper motor 11 installed on the bottom plate 14 for driving the picking and placing mechanisms to move on the slide block guide rail 17, and a photoelectric switch 15 installed at the bottom of the bottom plate 14.

[0021] There are two ball screw stepper motors 11, which are respectively mounted on the bottom plate 14 through the stepper motor mounting bases 13. A nut connection block 12 is sleeved on the nut of the ball screw stepper motor 11.

[0022] The three picking and placing mechanisms include side picking and placing mechanisms on both sides and a middle picking and placing mechanism in the middle. The middle picking and placing mechanism includes a first picking block 7 mounted on the slider guide rail 17. The side picking and placing mechanism includes a second picking block 9. One side of the second picking block 9 is connected to one side of the slide rail mounting plate 10. The slide rail mounting plate 10 is slidably mounted on the slider guide rail 17. The other side of the slide rail mounting plate 10 is connected to one side of the nut connection block 12. By starting the rotation of the ball screw stepper motor 11 to drive the movement of the nut connection block 12 and then drive the movement of the two side picking and placing mechanisms, the distance between the three picking and placing mechanisms can be adjusted to adapt to the picking and placing of filter elements of different sizes. The cylinders 4 are mounted on the tops of both the first picking block 7 and the second picking block 9. The piston rods of the cylinders 4 are arranged downward and a floating joint 16 is mounted at the end. A filter element push rod 8 is mounted at the bottom of the floating joint 16. A pipe joint 2 is provided on the filter element push rod 8. The inside of the filter element push rod 8 is hollow and the lower end is provided with a chamfer, which plays a guiding role when the filter element 1 is sucked in.

[0023] The lower ends of the first picking block 7 and the second picking block 9 are provided with picking and placing cavities for the filter element push rod 8 to insert. An O-ring 3 is provided in the picking and placing cavity to play a sealing role. A proximity switch sensing piece 6 is provided at the bottom of the slide rail mounting plate 10. A synchronous belt guard 5 is provided on the top of the bottom plate 14.

[0024] In the present utility model, the bottom plate 14 is mounted on the Z-axis of the manipulator. The pipe joint 2 is connected to a negative pressure device. The filter element 1 is conveyed through a vibrating disk. When it is conveyed below the picking and placing mechanism, the cylinder 4 is started to drive the piston rod to descend, and when the distance between the filter element push rod 8 and the filter element 1 is 0.5 - 1 mm, the negative pressure device is started to suck the filter element 1 upward. Then, the manipulator drives the entire assembly mechanism to move above the battery. Then, the cylinder 4 is started again to drive the piston rod to descend and drive the filter element push rod 8 to move downward to push the filter element 1 out of the picking and placing cavity, completing the picking and placing of the filter element. By setting three picking and placing mechanisms, the picking and placing of 3 filter elements can be realized at one time, improving the efficiency.
