Example 1

Referring to fig. 1 to 4, a sampler 100 according to an embodiment of the present utility model is provided. The sampler 100 is used for cutting and sampling the pole piece 200.

The pole piece 200 in this embodiment is a pole piece in a lithium battery, and a coating is coated on the surface of the pole piece 200.

Referring to fig. 1, the sampler 100 includes a first rotating roller 110, a second rotating roller 120, a side plate 130, a telescopic cylinder 140 and a sampling cutter 111.

The end of the second rotating roller 120 is rotatably connected with the side plate 130; the first rotating roller 110 is located right above the second rotating roller 120; the telescopic cylinder 140 is fixed on the side plate 130, and the first rotating roller 110 is rotatably arranged at the output end of the telescopic cylinder 140; the sampling cutter mold 111 is fixed to the first rotating roller 110.

The telescopic cylinder 140 is used for driving the first rotating roller 110 to move downwards, so that the first rotating roller 110 and the second rotating roller 120 respectively press the upper surface and the lower surface of the pole piece 200; and then the sampling knife mold 111 performs cutting sampling on the pole piece 200 when the first rotating roller 110 rotates.

As shown in fig. 2, the side plate 130 includes a first side plate and a second side plate, and two ends of the second rotating roller 120 are respectively connected with the first side plate and the second side plate in a rotating manner; so that the second rotating roller 120 can rotate when the first rotating roller 110 and the second rotating roller 120 press the upper and lower surfaces of the pole piece 200, respectively.

The telescopic cylinder 140 is fixed to the top of the side plate 130.

The sampler 100 further includes a sliding block 150, a sliding groove is formed on the side plate 130, and the sliding block 150 is movably disposed in the sliding groove.

The end of the first rotating roller 110 is rotatably connected with the slider 150, and the output end of the telescopic cylinder 140 is fixedly connected with the slider 150.

The telescopic cylinder 140 drives the sliding block 150 to move in the sliding groove, so as to drive the first rotating roller 110 to move along the opening direction of the sliding groove.

In some embodiments, the opening direction of the sliding groove on the side plate 130 is a vertical direction, so that the telescopic cylinder 140 indirectly drives the first rotating roller 110 to move along the vertical direction through the sliding block 150.

In some embodiments, the output end of the telescopic cylinder 140 is fixedly connected to the slider 150 by welding.

The sampler 100 further includes a seated bearing 160, the seated bearing 160 includes a first seated bearing and a second seated bearing, the end of the first rotating roller 110 is disposed in the first seated bearing, and the first seated bearing is fixed on the slider 150 by a screw.

The end of the first rotating roller 110 is rotatable in the first belt seat bearing.

The end of the second rotating roller 120 is disposed in the second seated bearing, and the second seated bearing is fixed to the side plate 130 by a screw. The end of the second rotating roller 120 is rotatable in the second seated bearing.

Referring to fig. 3 and 4, the pole piece 200 is disposed between the first rotating roller 110 and the second rotating roller 120. When the sampler 100 is not in operation, the telescopic cylinder 140 drives the first rotating roller 110 to move upwards through the sliding block 150, so that the first rotating roller 110 is far away from the second rotating roller 120.

When the sampler 100 works, the telescopic cylinder 140 drives the first rotating roller 110 to move downwards through the sliding block 150, so that the first rotating roller 110 presses the upper surface of the pole piece 200, and the second rotating roller 120 presses the lower surface of the pole piece 200.

When the sampler 100 works, the first rotating roller 110 and the second rotating roller 120 can be driven to rotate by moving the pole piece 200; since the first rotating roller 110 presses the pole piece 200 downward, when the pole piece 200 is in contact with the sampling die 111 on the first rotating roller 110, the sampling die 111 can press the pole piece 200 downward to cut and sample the pole piece 200.

In some embodiments, after the pole piece 200 is punched by the sampling cutter 111, the sampling hole 210 formed on the pole piece 200 is a circular hole. However, it is understood that in other embodiments, the operator may change the shape of the sampling die 111 as needed, so that the sampling holes 210 formed on the pole piece 200 are square holes or bar holes after the sampling die 111 punches the pole piece 200.

In some embodiments, the sampler 100 is provided with a buckle, the first rotating roller 110 is provided with a buckle hole corresponding to the buckle, and the buckle is matched with the buckle hole, so that the sampling cutter die 111 is fixed on the first rotating roller 110.

The sampler 100 further includes an elastic pad 112, where the elastic pad 112 is disposed in the sampling cutter 111, and an upper surface of the elastic pad 112 is slightly higher than an upper surface of the sampling cutter 111.

When the sampler 100 works, as the first rotating roller 110 rotates, the pressure of the sampling cutter mold 111 on the pole piece 200 gradually increases, the reaction force of the pole piece 200 on the elastic gasket 112 compresses the elastic gasket 112, so that the sampling cutter mold 111 can perform punching sampling on the pole piece 200, and a sample cut on the pole piece 200 is attached in the sampling cutter mold 111.

With further rotation of the first rotating roller 110, the pressure of the sampling cutter mold 111 on the pole piece 200 gradually decreases, and the elastic force of the elastic gasket 112 during recovery can promote the automatic separation of the sample from the sampling cutter mold 111, so as to avoid manual separation of the sample from the sampling cutter mold 111.

In some embodiments, the sampler 100 includes a plurality of the sampling dies 111, and the plurality of sampling dies 111 are disposed on the first rotating roller 110 at intervals along the axial direction of the first rotating roller 110.

Through the mode, the sampler can sample a plurality of positions of the pole piece 200 in the transverse direction at the same time, so that fluctuation of the coating density of the pole piece 200 in the transverse direction can be effectively reflected, sampling data is more accurate, and quantitative analysis conditions are provided.

In some embodiments, the sampler 100 includes a plurality of sampling dies 111, and the plurality of sampling dies 111 are disposed on the first rotating roller 110 at intervals along the circumferential direction of the first rotating roller 110.

In this way, the sampler can sample a plurality of positions of the pole piece 200 in the longitudinal direction at the same time, so that fluctuation of the coating density of the pole piece 200 in the longitudinal direction can be effectively reflected.

In some embodiments, the sampler 100 includes a plurality of sampling dies 111, at least two sampling dies 111 are disposed on the first rotating roller 110 at intervals along the axial direction of the first rotating roller 110; at least two sampling dies 111 are disposed on the first rotating roller 110 at intervals along the circumferential direction of the first rotating roller 110.

In this way, the sampler can sample a plurality of positions in the transverse direction as well as the longitudinal direction of the pole piece 200 at the same time.

The sampler 100 provided in this embodiment is formed by rotationally connecting the end of the first rotating roller 110 and the end of the second rotating roller 120 with the side plate 130, respectively; the output end of the telescopic cylinder 140 can drive the first rotating roller 110 to move downwards, so that the first rotating roller 110 and the second rotating roller 120 respectively press the upper surface and the lower surface of the pole piece 200; the first rotating roller 110 can rotate along with the transmission of the pole piece 200, and when the first rotating roller 110 rotates, the sampling cutting die 111 on the first rotating roller 110 can punch the pole piece 200, so that the pole piece 200 is cut and sampled. The sampler 100 of the utility model has high automation degree, and can sample in the conveying process of the pole piece 200, so that the production efficiency of the coated pole piece 200 is not affected.
