Specifically, the material taking drive member 1231 and the material discharging drive member 1232 are both cylinders.

[0038] In specific application, when the rotating mechanism 11 drives the pick-up and placement mechanism 12 to rotate to the corresponding pole piece, the pick-up and placement driving member 1231 generates a driving force to drive the pick-up and placement support plate 1212 to move toward the pole piece, and the pick-up and placement support plate 1212 drives the pick-up and placement movable plate 1213 and the ball plate 1214 to move toward the pole piece, and the pick-up and placement movable plate 1213 drives the suction plate 1221 to move toward the pole piece, and the suction plate 1221 generates suction to suck the pole piece. At this time, the pick-up and placement reset member 1214 is stretched, and the suction plate 12 After the electrode is sucked, the material taking driving member 1231 returns to the initial state, the stretched material taking and placing reset member 1214 returns to the initial unstretched state, and the elastic force of the material taking and placing reset member 1214 drives the material taking and placing support plate 1212, the material taking and placing movable plate 1213, the ball plate 1214 and the suction plate 1221 to return to the initial position, and then the turntable 112 rotates to drive the taking and placing mechanism 12 and the electrode to pass through the electrode position detection component 131 and the electrode taking and placing deviation correction component 132 in turn to reach the diaphragm patch station, and the material is discharged.

The stretched material picking and placing reset piece 1214 needs to return to its initial unstretched state, and the elastic force of the material picking and placing reset piece 1214 drives the material picking and placing support plate 1212, the material picking and placing movable plate 1213, the ball plate 1214 and the suction plate 1221 to return to their initial positions.

The pole piece picking and placing correction driving component 1323 is arranged on the pole piece picking and placing correction alignment platform 1322. The pole piece picking and placing correction component 1324 is arranged at the output end of the pole piece picking and placing correction driving component 1323, specifically, the pole piece picking and placing correction driving component 1323 is a cylinder.

[0042] Specifically, the pole piece taking and placing correction member 1324 includes a correction plate 13241 and a correction needle 13242.

At this time, the electromagnetic clutch 12121 installed on the pick-up and release support plate 1212 is powered off, the magnetism disappears, the pick-up and release movable plate 1213 is separated from the pick-up and release support plate 1212, and the pick-up and release movable plate 1213 slides on the ball plate 1125, and the pick-up and release movable plate 1213 drives the suction plate 1221 that has sucked the pole piece to slide, thereby achieving The position of the pole piece is now corrected so that it is in a predetermined position. At the same time, the pole piece picking and placing correction drive 1323 continues to drive the correction needle 13242 to move, so that the correction needle 13242 is completely inserted into the correction block 1222, and the pole piece is corrected. After the correction, the electromagnetic clutch 12121 is energized, so that the material picking and placing movable plate 1213 is again magnetically adsorbed on the material picking and placing support plate 1212, and then, the turntable 112 drives the corrected pole piece to rotate to the diaphragm patch station to perform the pole piece pasting action.

The dust removal drive member 154 is arranged on the connecting plate 155, and the output end of the dust removal drive member 154 is connected to the dust removal brush 153, and specifically, the dust removal drive member 154 is a cylinder.

[0051] The pick-and-place fixture anti-static mechanism 16 is arranged on the dust removal mounting seat 151. Specifically, the pick-and-place fixture anti-static mechanism 16 is an ion wind aluminum rod, which is easy to install, safe and stable to work, and has a fast anti-static speed.

[0052] During specific application, the turntable 112 drives the aligned pick-and-place jig 122 to rotate to the working position of the dust removal mechanism 15, and the dust removal moving drive 152 drives the connecting plate 155 to move toward the pick-and-place jig 122, and the connecting plate 155 drives the dust removal brush 153 to move to abut the suction plate 1221, and then, the dust removal drive 154 drives the dust removal brush 153 to rotate to remove dust from the surface of the suction plate 1221, and the removed dust is sucked away through the vacuum tube. At the same time, the pick-and-place jig anti-static mechanism 16 removes static electricity from the surface of the suction plate 1221 to prevent static electricity from affecting subsequent operations.

[0053] In specific applications, the above-mentioned rotating mechanism 11, the pick-up and placement mechanism 12, the position adjustment mechanism 13, the fixture alignment mechanism 14, the dust removal mechanism 15 and the pick-up and placement fixture anti-static mechanism 16 are all electrically connected to the control system of the electrode pick-up and placement device 1, and the control system of the electrode pick-up and placement device 1 controls the rotation mechanism 11, the pick-up and placement mechanism 12, the position adjustment mechanism 13, the fixture alignment mechanism 14, the dust removal mechanism 15 and the pick-up and placement fixture anti-static mechanism 16 to achieve the effect of automatic control of the electrode pick-up and placement device 1. Of course, the control system of the electrode pick-up and placement device 1 can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be repeated here.

[0054] To sum up, in one or more embodiments of the present invention, the electrode piece picking and placing device of the present invention adjusts the position of the electrode piece sucked by the picking and placing mechanism through a position adjustment mechanism to ensure that the electrode piece is attached to the predetermined position of the diaphragm, thereby improving the yield rate of the battery cell. In addition, the position adjustment mechanism is arranged on the outside of the picking and placing mechanism, which effectively reduces the weight of the rotating mechanism, allowing the rotating mechanism to operate at high speed, thereby increasing the feeding speed.

[0055] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
