Referring to fig. 1, the pole piece conveying device in the present embodiment includes a first pole piece conveying device 100 and a second pole piece conveying device 200. From the perspective of fig. 1, the first pole piece conveyor 100 is located to the right of the second pole piece conveyor 200. The pole pieces are first adsorbed by the top of the left end of the second pole piece conveyor 200 and are transported from left to right to the left end of the first pole piece conveyor 100. Then absorbed by the bottom of the first pole piece conveying device 100 and continuously transported from left to right.

Referring to fig. 2, the first pole piece transporting device 100 includes transporting rollers (including a driving roller 111 and a plurality of driven rollers 112), a driving roller driving member 120, a belt 130, a tension driving member 140, a vacuum duct assembly 150, a defective NG box 160, a size NG box 170, and a first frame 180. The feed roller is connected to the frame 180 and the belt 130 is held in tension by the feed roller. The belt 130 is provided with a hole 131, and the vacuum pipe assembly 150 keeps the negative pressure at the hole 131 to adsorb the pole piece on the surface of the belt 130. During transportation, the pole piece is adsorbed by the lower surface of the belt 130 and passes through the flaw NG box 160 and the size NG box 170 in sequence.

Referring to fig. 2 and 3, the driving roller driving member 120 is a motor, and the motor drives the driving roller 111 to rotate through the transmission belt 121 and the pulley 122, so that the belt 130 sleeved on the driving roller 111 rotates together to complete the transportation. The driving roller 111 is provided with a bump 1111 for dividing the driving roller 111 into two parts to form two conveying surfaces 1112, but the driving roller may be provided with a bump for division. The belt 130 is disposed on one of the conveying surfaces 1112 and is abutted against each other to tension the belt 130. Because two conveying surfaces 1112 are arranged, two belts can be arranged, and two conveying lines can be conveyed at the same time.

The structure of the driven roller 112 is similar to that of the driving roller 111, and referring to fig. 4 and 5, the driven roller 112 is provided with a groove 1121 to divide the driving roller 112 into two parts to form two conveying surfaces 1122. But providing a groove can reduce the processing time compared to providing a bump. The belt 130 is disposed on one of the conveying surfaces 1122, and the two conveying surfaces abut against each other to tension the belt 130.

The conveying surface of at least part of the conveying roller protrudes toward the belt 130 to limit the belt 130 so that it is not easily displaced. The driven roller 112 will be described as an example. Both the conveying surfaces 1122 on the driven roller 112 project outward. Specifically, in the width direction, the distance between both ends of the conveying surface 1122 and the axis of the driven roller 112 is smaller than the distance between the center of the conveying surface 1122 and the axis of the driven roller 112, that is, the driven roller 112 has a drum shape. After the belt 130 is sleeved on the conveying surface 1122 of the driven roller 112, the outwardly protruding conveying surface 1122 is attached to the belt 130, so that the distance between the belt 130 and the axis of the driven roller 112 in the width direction of the belt 130 gradually decreases from the center to both sides. Preferably, the difference obtained by subtracting the distance between the center of the belt 130 in the width direction and the axis of the driven roller 112 from the distance between the ends of the belt 130 in the width direction and the axis of the driven roller 112 is in the range of 0.4mm to 0.8mm, more preferably 0.6 mm.

Compared with a common cylindrical roller, the belt 130 can be better limited by the drum-shaped roller, the convex conveying surface 1122 can enable the belt 130 to be higher in tightness, and if the belt needs to be displaced in the width direction in the conveying process, the blocking of the convex conveying surface 1122 needs to be overcome, so that the belt has a better limiting effect.

Referring to fig. 2 and 6, a tension driver 140 is disposed on the top of a portion of the driven roller 112, and in this embodiment, the tension driver 140 is an air cylinder. The driven roller 112 is fixedly connected with the telescopic end of the air cylinder, the driven roller 112 connected with the driven roller is driven by the air cylinder to move along the vertical direction, the tensioning degree of the belt 130 is adjusted, the situation that the tensioning degree is not enough when the belt 130 is long is avoided, looseness occurs in partial positions is avoided, the stability of the belt 130 during transportation is improved, and the shaking degree is reduced.

Referring to fig. 7, the second pole piece transfer device 200 in this embodiment is arranged in a manner similar to the first pole piece transfer device 100. The second pole piece conveying device 200 includes a second conveying roller (including a second driving roller 211 and a plurality of second driven rollers 212), a second driving roller driving member 220, a second belt 230, a second tension driving member 240, a second vacuum duct assembly 250, a brush assembly 260, a second frame 270, and the like.

Referring to fig. 7 and 8, the second driving roller driving member 220 is a motor, and the motor drives the second driving roller 211 to rotate through the second conveying belt 221 and the second belt wheel 222, so that the second belt 230 sleeved on the second driving roller 211 rotates together to complete the transportation.

Referring to fig. 7 and 9, in the second pole piece transfer device 200, the shape of a part of transfer rollers is similar to that of the first pole piece transfer device 100. The conveying surface of part of the conveying rollers protrudes toward the second belt 230 to form a drum-shaped roller, so that the limit of the second belt 230 is enhanced, and the second belt is not easy to shift. The conveying roller of the second pole piece conveying device 200 is provided with only one conveying surface, and only one belt can be sleeved on the conveying roller at the same time, but the invention is not limited to this, and the first pole piece conveying device 100 can also be referred to, and two belts are provided with two grooves or projections to form two conveying surfaces by separation.

Referring to fig. 7 and 10, similar to the first pole piece conveyor 100, in the second pole piece conveyor 200, a second tensioning driving member 240 is disposed at the top of a portion of the second driven roller 212, and in this embodiment, the second tensioning driving member 240 is an air cylinder. The second driven roller 212 is fixedly connected with the telescopic end of the air cylinder, and the air cylinder drives the second driven roller 212 connected with the air cylinder to move along the vertical direction so as to adjust the tensioning degree of the second belt 230.

Referring to fig. 7 and 11, the brush assembly 260 includes a vacuum suction cover 261, a brush driving member 262, a brush driving belt 263, a brush driving pulley 264, and a brush (not shown). The brush is in contact with the surface of the second belt 230, and the vacuum adsorption cover 261 covers the outside of the brush. The brush driving member 262 is a motor, which drives the brush to rotate via the brush driving belt 263 and the brush driving belt wheel 264 to lift the dust attached to the surface of the second belt 230, and the lifted dust is sucked by the vacuum absorption cover 261 to maintain the cleanliness of the surface of the second belt 230.
