The present application provides an online sampling device 001 for a battery electrode, and fig. 1 is a schematic structural diagram of the online sampling device 001 for a battery electrode provided in the present application. The on-line sampling device 001 of the battery pole piece can be used for on-line sampling of the battery pole piece 700 moving at a high speed in the operation process of the production line 800, and the on-line sampling device 001 of the battery pole piece can be applied to the battery coating process and the battery pole piece rolling process. Of course, the on-line sampling device 001 for battery pole pieces can also be used for on-line sampling in other production lines, such as production lines of surface coating processes of paper, base film and the like. A series of arrows are labeled in fig. 1, the direction of the arrows being the direction of movement of the battery pole piece 700.

As shown in fig. 1, the battery pole piece on-line sampling device 001 may include a sampling device 200. In some embodiments, the battery pole piece in-line sampling device 001 may also include an adhesion device 100. In some embodiments, a control device 300 may also be included. The adhesive device 100 may attach a protective device such as a tape to a target position of the battery pole piece 700. The control device 300 may control the sampling device 200 to sample the target position. The adhesive device 100 can protect the target site from pole piece breakage after sampling. It should be noted that, without the adhesion device 100, the sampling device 200 can still realize online sampling of the battery pole piece 700 during high-speed movement.

The adhesive device 100 can be mounted in a first fixed position 810 of the battery pole piece production line 800 and can be configured to adhere the tape 101 to a target location of the battery pole piece 700. The target position may be any position of the battery pole piece 700. When the adhesive tape 101 is adhered to the battery tab 700, the position of the battery tab 700 where the adhesive tape 101 is adhered is defined as the target position. The adhesion device 100 may include an adhesion driving device 110 and an adhesion mechanism 130. The tape 101 is attached to the attachment mechanism 130. The adhesion mechanism 130 is driven by the operation of the adhesion driving device 110 to adhere the tape 101 to the battery pole piece 700. The adhesive device 10 can adhere the adhesive tape 101 to the battery pole piece 700, and can protect the battery pole piece 700 from breaking after sampling.

The tape 101 may be attached to the outer surface 134 of the roller 131. The outer surface 134 of the roller 131 may be of a friction increasing material such as rubber or the like. Grooves may also be machined into the outer surface 134 to increase friction and increase adhesion of the tape 101. The pressure within the negative pressure cavity 136 may be less than the ambient atmospheric pressure. The suction hole 138 may communicate the negative pressure chamber 136 with the outer surface 134 of the roller 131. When the pressure of the sub-pressure chamber 136 is less than the atmospheric pressure, the adhesive tape 101 may be attached to the outer surface 134 of the roller 131 through the suction hole 138 by the pressure difference.

The swing arm 140 can rotate about the first hinge end 141. When the adhesion device 100 works, the adhesion driving device 110 contracts, the swing arm 140 is pulled to rotate around the first hinged end 141, so that the roller 131 is pressed through the roller 830, the roller 131 rotates around the second hinged end 142, and the adhesive tape 101 attached to the outer surface 134 of the roller 131 is adhered to the battery pole piece 700. When the adhesion device 100 is not in operation, the adhesion driving device 110 is extended to push the swing arm 140 to rotate around the first hinged end 141, so that the roller 131 leaves the roller 830.

As shown in fig. 3, the cut portion in the middle of the tape 101 is a sampling portion 102, and the position where the sampling portion 102 is stuck to the battery tab 700 is the target position. When the adhesion device 100 is operated, the adhesion driving device 110 is contracted, the swing arm 140 is pulled to rotate around the first hinged end 141, so that the roller 131 is pressed through the roller 830, and the roller driving device 160 drives the roller 131 to rotate around the second hinged end 142, so that the adhesive tape 101 attached to the outer surface 134 of the roller 131 is adhered to the battery pole piece 700. When the adhering device 100 is not in operation, the adhering driving device 110 is extended to push the swing arm 140 to rotate around the first hinged end 141, so that the roller 131 leaves the roller 830, and the roller driving device 160 stops operating.

In summary, when the adhesion driving device 110 is operated, the roller 131 is pressed against the roller 830, so that the adhesive tape 101 attached to the outer surface 134 of the roller 131 is adhered to the battery pole piece 700 to protect the battery pole piece 700.

As shown in fig. 1, the sampling device 200 may be mounted at a second fixed location 820 of the battery pole piece production line 800 and may be configured to enable on-line sampling of the target location on the production line 800 where the moving battery pole piece 700 is adhered with the adhesive tape 101.

Fig. 5 shows a cross-sectional view C-C of the down sampler 211 of fig. 4. As shown in fig. 5, the down-sampler 211 may include a female mold 212. The female die 212 may be a punched hole on the down-sampler 211.

The down drive 213 may be configured to drive the down sampler 211 to rotate relative to the down sampling mechanism 210. The lower driving unit 213 may be directly connected to the pivot shaft 215 or indirectly connected to the pivot shaft 215 via a transmission mechanism 218, thereby driving the rotation of the lower sampler 211. The lower driving device 213 may be a servo motor, a stepping motor, a synchronous motor, or the like. The transmission 218 may be a gear transmission, or may be one or more of a chain transmission, a belt transmission, and a worm gear.

Lower bearing housing 216 may be mounted on lower stationary surface 821 and lower drive 213 may drive rotation of lower sampler 211 relative to lower bearing housing 216.

The first positioning means 220 may be configured as positioning means of the down-sampler 211 in the lateral direction. The transverse direction refers to the axial direction of the rotation axis of the down-sampler 211, or the axial direction of the pivot 215. The first positioning device 220 may include a first lead screw 221, a first stop 223, a second stop 225, and a first handle 227. The first lead screw 221 may be rotatably coupled to the down-sampling mechanism 210. Further, the first lead screw 221 can be rotatably connected with the lower bearing seat 216. The axial direction of the first lead screw 221 coincides with the lateral direction. The first shutter 223 may be slidably mounted on the first lead screw 221. The first baffle 223 may include a nut (not shown in fig. 4). The nut is engaged with the first lead screw 221. The nut is fixedly connected with the first barrier 223. By rotating the first lead screw 221, the nut drives the first baffle 223 to slide in the axial direction of the first lead screw 221.

second baffle plates

223 and 225 are coupled together by bolts 228 and nuts 229, and the down-sampler 211 is sandwiched between the first and

second baffle plates

223 and 225. The first handle 227 may be coupled to the first lead screw 221. The first lead screw 221 can be rotated by rotating the first handle 227. When the first handle 227 is rotated, the first lead screw 221 rotates together with the first handle 227, and the first baffle 223 and the second baffle 225 drive the lower sampler 211 to slide in the transverse direction, so that the position of the lower sampler 211 in the transverse direction is adjusted; when the first handle 227 stops rotating, the first lead screw 221 has a self-locking function, and fixes the first barrier 223, the second barrier 225, and the down-sampler 211 at the current position.

In summary, the down sampler 211 can move in the transverse direction under the action of the first positioning device 220 to achieve positioning in the transverse direction. The position of the down sampler 211 in the transverse direction depends on the position of the adhesive tape 101 adhering on the cell pole piece 700. The position of the down-sampler 211 in the transverse direction needs to be consistent with the position of the adhesive tape 101 stuck in the transverse direction, so that the sampling part 102 stuck by the adhesive tape 101 can be accurately sampled.

The male mold 232 may engage the female mold 212.

The up-drive mechanism 233 may be configured to drive the up-sampler 231 to rotate relative to the up-sampling mechanism 230. The upper drive unit 232 may be directly connected to the pivot shaft 235 or indirectly connected to the pivot shaft 235 through a transmission mechanism 238, thereby driving the rotation of the upper sampler 231. The upper driving device 233 may be a servo motor, a stepping motor, a synchronous motor, or the like. The transmission 238 may be a gear transmission, or may be one or more of a chain transmission, a belt transmission, and a worm gear.

The upper bearing housing 236 may be directly or indirectly connected to the upper fixing surface 823, and the upper driving unit 233 may drive the upper sampler 231 to rotate relative to the upper bearing housing 236.

By rotating the second lead screw 241, the third flapper 243 can slide in the axial direction of the second lead screw 241. The third barrier 243 may be provided at one side of the upper sampler 231. The fourth blocking plate 245 may be slidably mounted on the second lead screw 241. The fourth baffle 245 may include a nut (not shown in fig. 4). The nut is engaged with the second lead screw 241. The nut is fixedly connected with the fourth baffle 245. By rotating the second lead screw 241, the fourth shutter 245 can slide in the direction of the lateral axis of the second lead screw 241. A fourth baffle 245 may be provided on the opposite side of the upper sampler 231 from the third baffle 243. Third apron 243 and fourth apron 245 are coupled together by bolts 248 and nuts 249, and upper sampler 231 is sandwiched between third apron 243 and fourth apron 245. The second handle 247 may be connected to the second lead screw 241, and the second lead screw 241 may be rotated by rotating the second handle 247. When the second handle 247 is rotated, the second lead screw 241 rotates together with the second handle 247, and the third and

fourth stoppers

243 and 245 slide the upper sampler 231 in the transverse direction, so that the position of the upper sampler 231 in the transverse direction is adjusted, so that the male mold 232 of the upper sampler 231 and the female mold 212 of the lower sampler 211 can be completely engaged, and the engaged position can cover the target position to which the adhesive tape 101 is adhered; when the second handle 247 stops rotating, the second lead screw 241 has a self-locking function, and fixes the third barrier 243, the fourth barrier 245 and the up-sampler 231 at the current position.

In summary, the upper sampler 231 can move in the transverse direction under the action of the second positioning device 240 to achieve positioning in the transverse direction. The position of the up-sampler 231 in the lateral direction depends on the position of the down-sampler 211 in the lateral direction.
