Detailed Description

Referring to fig. 1 to 7, a feeding deviation correcting device according to an embodiment of the present invention mainly includes a clamping mechanism 10, a deviation correcting driving mechanism 30, a feeding driving mechanism 20, and a deviation correcting detector. The pole pieces pass through the clamping mechanism 10 and extend to the winding mechanism.

The driving end of the deviation-rectifying driving mechanism 30 is linked with the clamping piece mechanism 10, and the deviation-rectifying driving mechanism 30 is started, so that the clamping piece mechanism 10 can be driven to reciprocate in the deviation-rectifying direction; the driving end of the sheet feeding driving mechanism 20 is linked with the sheet clamping mechanism 10, and the sheet feeding driving mechanism 20 is started, so that the sheet clamping mechanism 10 can be driven to reciprocate in the pole piece conveying direction.

The linkage is a power connection, the deviation correcting driving mechanism 30 can provide a power source pointing to the deviation correcting direction, and the sheet feeding driving mechanism 20 can provide a power source pointing to the sheet feeding direction. The clamping mechanism 10 is used to clamp or unclamp pole pieces passing through its interior. The clamping mechanism 10 can realize the pole piece deviation rectifying function and the pole piece feeding function by the power of the deviation rectifying driving mechanism 30 and the pole piece feeding driving mechanism 20. The deviation rectifying detector is used for detecting the offset of the pole piece. The offset is equal to the displacement of the clip mechanism 10 driven by the deviation correcting driving mechanism 30 in the deviation correcting direction.

The feeding deviation correcting device realizes the combination of the functions of pole piece feeding and deviation correction, and the deviation correction of the pole piece can be realized by driving the clamping piece mechanism 10 to reciprocate in the deviation correcting direction through the deviation correcting driving mechanism 30; meanwhile, the sheet feeding driving mechanism 20 drives the sheet clamping mechanism 10 to reciprocate in the conveying direction of the pole pieces, so that the pole pieces can be conveyed. The deviation-rectifying driving mechanism 30 moves forward along with the pole piece, so that the deviation-rectifying position approaches to the winding station to the maximum extent, and the deviation-rectifying effect is remarkable.

Specifically, the clip mechanism 10 includes an upper clip 101, a lower clip 102, and a clip driving mechanism, and the clip driving mechanism can drive the upper clip 101 or the lower clip 102 to move in the vertical direction of the upper and lower surfaces of the pole piece, so that the two clips make relative or back-to-back movement. In this embodiment, the clamping piece is driven to drive the cylinder 103, the cylinder rod of the cylinder 103 is fixedly mounted with the lower clamping piece 102, the cylinder body of the cylinder 103 is fixedly mounted with the upper clamping piece 101, and the upper clamping piece 101 and the lower clamping piece 102 can be close to and far away from each other through the expansion and contraction of the cylinder rod, so that the clamping and loosening of the pole piece can be completed. Meanwhile, the installation modes of the driving cylinder 103, the upper clamping piece 101 and the lower clamping piece 102 can be exchanged, and the principle is the same. The driving cylinder 103 can also be installed on the frame, the cylinder rod is fixedly connected with one of the clamping pieces, and the driving cylinder 103 drives the clamping piece to move up and down.

Preferably, a first pressing wheel 1011 is rotatably disposed on the upper clamping piece 101, a second pressing wheel 1021 is rotatably disposed on the lower clamping piece 102, and the first pressing wheel 1011 and the second pressing wheel 1021 are disposed opposite to each other. The first pressing wheel 1011 and the second pressing wheel 1021 move relatively to be respectively abutted against the upper surface and the lower surface of the pole piece, and the pole piece between the first pressing wheel 1011 and the second pressing wheel 1021 is clamped tightly, so that the pole piece can be stably conveyed to a winding station.

Meanwhile, in order to avoid the pole piece from retracting in the pole piece conveying process, the second pressing wheel 1021 is set to rotate in a single direction, and the rotating direction of the second pressing wheel 1021 is consistent with the conveying direction of the pole piece. The pole piece is slightly deformed due to the fact that tension is applied to the pole piece to a certain degree in the winding process, and then the pole piece has the tendency of restoring deformation. After the pole piece is cut, the retraction of the pole piece may cause the reverse rotation of the first pressing wheel 1011 and the second pressing wheel 1021, and then the pole piece is driven reversely, so that the end of the pole piece is separated from the gap between the first pressing wheel 1011 and the second pressing wheel 1021, and the device cannot perform subsequent actions. Once the second pressing wheel 1021 is set to rotate in one direction, the rotation can be avoided, and the stability of the whole device is ensured.

preferably, the first and second pressing rollers 1011 and 1021 are disposed at front end portions of the upper and lower jaws 101 and 102, respectively. The detection position of the deviation-correcting detector is arranged close to the first pinch roller 1011 and the second pinch roller 1021, and is positioned behind the first pinch roller 1011 and the second pinch roller 1021. The deskew detector may be a deskew optical fiber mounted on a rack. And in the process of feeding the pole piece, the deviation of the pole piece is detected by the deviation-rectifying optical fiber. The offset can be fed back to the deviation correction driving mechanism 30, and the deviation correction driving mechanism 30 drives the clamping piece mechanism 10 to move in the deviation correction direction, so that the pole pieces are conveyed to the winding station along the correct direction under the clamping of the first pressing wheel 1011 and the second pressing wheel 1021.

Meanwhile, the front end of the upper clamping piece 101 is provided with an upper pressing block 1012 pointing to the pole piece conveying direction, the front end of the lower clamping piece 102 is provided with a lower pressing block 1022 pointing to the pole piece conveying direction, and a gap for the pole piece to pass through is formed in front of the upper pressing block 1012 and the lower pressing block 1022. The pole piece passes through the gap between the first pressing wheel 1011 and the second pressing wheel 1021 and then penetrates out. This gap has formed one section rigid clamping piece passageway, compares in the pole piece and directly wears out between first pinch roller 1011 and second pinch roller 1021, can avoid the pole piece to take place rocking by a relatively large margin in the centre gripping department of first pinch roller 1011 and second pinch roller 1021, has ensured the stability of centre gripping.

The first lead screw assembly comprises a first lead screw 33 and a first bearing seat 34 sleeved on the first lead screw 33, the first motor 31 drives the first lead screw 33 to rotate forwards and backwards, the first bearing seat 34 moves in a reciprocating mode along the deviation rectifying direction, and the clamping piece mechanism 10 is fixedly connected with the first bearing seat 34 through a first rigid connecting piece 50 to achieve synchronous movement.

The second lead screw 22 is synchronously and rotatably mounted on an output shaft driven by the second motor 21 through a coupler, and meanwhile, the second lead screw 22 is rotatably mounted on the rack through a bearing. The frame is provided with a pair of linear slide rails, the second rigid connecting piece 40 is a plate-shaped and can be a steel plate, the bottom surface of the steel plate is fixedly arranged with the second bearing seat 23, and the two side parts of the steel plate are connected with the linear slide rails in a sliding way. The linear slide provides support and guidance so that the second rigid link 40 can smoothly follow the second bearing housing 23 to and fro.

The deviation rectifying driving mechanism 30 is fixedly arranged on the second rigid connecting piece 40, and the whole body can move back and forth along with the second rigid connecting piece 40. Specifically, the first motor 31 is fixedly mounted on the second rigid connection member 40, and the first lead screw 33 is rotatably mounted on the second rigid connection member 40 through a bearing. When the first motor 31 is started, the belt transmission mechanism 32 can drive the first lead screw 33 to rotate, so as to drive the first bearing seat 34 to reciprocate in the deviation rectifying direction. The first rigid coupling member 50 may be a plate-shaped member or a steel plate having a bottom surface fixedly attached to the first bearing housing 34, and the first rigid coupling member 50 reciprocates along with the first bearing housing 34. Specifically, a guide shaft may be provided on the first rigid coupling member 50, the guide shaft extending through the lower clip 102 of the clip mechanism 10, and the entire clip mechanism 10 may be reciprocally moved along the guide shaft.
