[0022] When the suction cup 9 normally grabs the battery pole to the clamp inside the receiving component 4, the internal pressure of the suction cup 9 is released to release the battery pole. When the suction cup 9 leaves the surface of the battery pole, the force of the first spring 18 makes the bottom end of the square slide bar 11 always rest on the upper surface of the battery pole, ensuring that the instantaneous departure of the suction cup 9 will not cause the battery pole to move up and shake. This device avoids the shaking of the battery pole when the suction cup 9 leaves, thereby ensuring the accuracy of the battery pole position and ensuring the subsequent processing accuracy and quality.

[0023] In this embodiment, a plurality of partitions 801 are fixedly installed at equal intervals between the inner walls of the shell 8, and the shell 8 is divided into a plurality of cavities by the plurality of partitions 801. The top ends of the plurality of cylinders penetrate the inner wall of the shell 8 and are respectively connected to the plurality of cavities. A plurality of air pipe joints 802 are fixedly installed at equal intervals on the outer surface of one side of the shell 8, and one end of the plurality of air pipe joints 802 penetrates the inner wall of the shell 8 and is respectively connected to the plurality of cavities. A base 16 is fixedly installed on the bottom wall of the plurality of cavities, and a second compression cylinder 15 is fixedly installed on the upper surface of the base 16. A lower compression plate 23 is slidably installed on the inner wall of the second compression cylinder 15, and a middle position of the lower compression plate 23 A sliding column 21 is fixedly installed on the upper surface of the housing 8, and a second spring 24 is sleeved on the outer surface of the sliding column 21. The bottom end of the second spring 24 is fixedly connected to the upper surface of the lower compression plate 23, and the top end of the second spring 24 is fixedly connected to the top wall of the housing 8. The top end of the sliding column 21 passes through the upper surface of the housing 8 and is slidably installed therewith. A plurality of first compression cylinders 14 are fixedly installed on the upper surface of the housing 8 at equal intervals, and a plurality of exhaust holes are evenly opened on the outer surfaces of the plurality of first compression cylinders 14 near the bottom ends. An upper compression plate 22 is slidably installed on the inner wall of the first compression cylinder 14. The top end of the sliding column 21 is fixedly connected to the lower surface of the upper compression plate 22. The outer surface of the sliding column 21 A gap is set between the outer surface of the sliding column 21 and the port at the bottom end of the first compression cylinder 14, and a gap is also set between the outer surface of the sliding column 21 and the port at the top end of the second compression cylinder 15. A square hole 1601 is penetrated on the outer surface of the middle position of the base 16, and the square hole 1601 is matched with the square sliding rod 11. The square sliding rod 11 is slidably installed on the inner wall of the square hole 1601. The top ends of the multiple first compression cylinders 14 are fixedly installed with pipe joints, and the multiple pipe joints are connected through the connecting pipe 12. One end of the connecting pipe 12 is fixedly connected to the cylinder 13, and the cylinder 13 is vertically arranged. The top end of the cylinder 13 is fixedly installed with a second electrode 1302. The bottom end of the electrode 1302 is arranged inside the cylinder 13, and an air outlet is opened at the top of the cylinder 13. The first electrode 1301 is fixedly installed on the outer surface of the cylinder 13 near the bottom end, and the other end of the first electrode 1301 is arranged inside the cylinder 13. A material receiving component 4 is fixedly installed on the inner wall of one end of the vacuum loader body 1, and a vacuum generator 5 is fixedly installed on the inner wall of the other end of the vacuum loader body 1. An electromagnetic valve 6 is arranged on the outer surface of the vacuum generator 5. The electromagnetic valve 6 is connected to the air pipe joint 802 through a hose, and the other ends of the first electrode 1301 and the second electrode 1302 are electrically connected to the electromagnetic valve 6 through a wire.

[0024] Since the cavity inside the shell 8 is in a negative pressure state, the air inside the second compression cylinder 15 will expand, and then the upper compression plate 22 will be driven upward through the lower compression plate 23 and the slide column 21. The upper compression plate 22 pushes the conductive liquid from the first compression cylinder 14 through the connecting pipe 12 into the cylinder 13. Since the conductive liquid inside the cylinder 13 of multiple first compression cylinders 14 enters, the conductive liquid inside the cylinder 13 rises, so that the first electrode 1301 and the second electrode 1302 are electrically connected, and then the solenoid valve 6 receives the electrical signal and sends a command, so that the suction cup 9 can grasp normally. When the battery pole reaches the specified position, if one or more suction cups 9 fail to suck the battery pole, the conductive liquid inside the corresponding first compression cylinder 14 will not enter the interior of the cylinder 13, so that the solenoid valve 6 cannot receive the electrical signal of the electrical connection between the first electrode 1301 and the second electrode 1302, and then issues an abnormal instruction so that the suction cup 9 will not drive the battery pole to move. Through this device, it can be detected whether the suction cup 9 has firmly sucked all the battery poles, avoiding missing the battery poles and causing incorrect material sorting or position, thereby affecting the accuracy of the overall operation.

[0025] In this embodiment, a filter plate 19 is fixedly installed on the inner wall of the cylinder near the top, and a plurality of filter holes are evenly opened on the outer surface of the filter plate 19. A scraper cylinder 20 is rotatably installed on the upper surface of the mounting frame 10. A plurality of scraper rods are equidistantly fixedly installed on the circumferential outer surface of the scraper cylinder 20 near the top. The upper surfaces of the plurality of scraper rods are flush with the lower surface of the filter plate 19. The square slide bar 11 penetrates the inner wall of the scraper cylinder 20. The square slide bar 11 penetrates the outer surface of the filter plate 19 and is slidably installed therewith. A guide column 26 is fixedly installed on the outer surface of the square slide bar 11 located inside the scraper cylinder 20. A guide groove 25 is opened through the circumferential outer surface of the scraper cylinder 20. The guide groove 25 is spirally arranged, and the guide column 26 is slidably installed with the inner wall of the guide groove 25.

[0026] The upward movement of the square slide bar 11 drives the guide post 26 to move upward, and the guide post 26 drives the scraper 20 to rotate within a certain angle range through the guide groove 25. The scraper 20 drives the scraper rod to clean the lower surface of the filter plate 19 to prevent the dust on the surface of the battery pole from blocking the filter holes on the surface of the filter plate 19 and affecting the subsequent vacuuming effect.

[0027] In this embodiment, it should be noted that the interior of the first compression cylinder 14 , the connecting tube 12 and the cylinder 13 are filled with conductive liquid.

[0028] It should be noted that, before use, the present invention places the battery poles to be grasped in an equidistant manner in a placement box on the upper surface of the vacuum feeder body 1. When in use, the X-direction motion component 2 and the Y-direction motion component 3 are used to drive the suction cup 9 to move above the battery pole to be grasped, and then the Z-direction motion component 7 is used to drive the suction cup 9 to move close to the upper surface of the battery pole. The present device facilitates the subsequent grasping and moving of the battery pole. The square slide bar 11 is driven downward by the downward pressure of the suction cup 9. When the bottom end of the square slide bar 11 contacts the upper surface of the battery pole, the suction cup 9 continues to move downward so that the top end of the square slide bar 11 is inserted into the inside of the square hole 1601, and the inside of the second compression cylinder 15 is sealed. Then, the vacuum generator 5 is controlled to perform vacuum negative pressure suction on the cavity inside the shell 8 by controlling the host, so that the inside of the suction cup 9 is in a negative pressure state of a certain pressure, and the battery pole is firmly adsorbed under the suction cup 9. Since the cavity inside the shell 8 is in a negative pressure state, the air inside the second compression cylinder 15 will expand, and then the upper compression plate 22 is driven upward by the lower compression plate 23 and the slide column 21. The upper compression plate 22 pushes the conductive liquid from the first compression cylinder 14 through the connecting pipe 12 into the inside of the cylinder 13. The cylinder 13 has multiple The conductive liquid enters the first compression cylinder 14, causing the conductive liquid inside to rise, thereby electrically connecting the first electrode 1301 and the second electrode 1302, and then the solenoid valve 6 receives the electrical signal and issues a command, so that the suction cup 9 can normally grab the battery pole to the specified position. If one or more of the suction cups 9 do not suck the battery pole, at this time, the conductive liquid inside the corresponding first compression cylinder 14 will not enter the cylinder 13, so that the solenoid valve 6 cannot receive the electrical signal of the electrical connection between the first electrode 1301 and the second electrode 1302, and then issues an abnormal command so that the suction cup 9 will not drive the battery pole to move. The device can detect whether the suction cup 9 has firmly sucked all the battery poles, thereby avoiding missing the battery poles and causing the wrong material sorting or position, thereby affecting the accuracy of the overall operation; When the suction cup 9 normally grabs the battery pole to the fixture inside the material receiving assembly 4, the internal pressure of the suction cup 9 is released to release the battery pole. When the suction cup 9 leaves the surface of the battery pole, the bottom end of the square slide bar 11 is always against the upper surface of the battery pole through the force of the first spring 18, ensuring that the instantaneous departure of the suction cup 9 will not cause the battery pole to move upward and shake. The device avoids the shaking of the battery pole caused by the departure of the suction cup 9, thereby ensuring the accuracy of the position of the battery pole and ensuring the subsequent processing accuracy and quality; At the same time, the upward movement of the square slide bar 11 drives the guide column 26 to move upward, and the guide column 26 drives the scraper 20 to rotate within a certain angle range through the guide groove 25. The scraper 20 drives the scraper rod to clean the lower surface of the filter plate 19 to prevent the dust on the surface of the battery pole from blocking the filter holes on the surface of the filter plate 19 and affecting the subsequent vacuum effect.
