Description

Technical Field

[0001] The utility model relates to the field of battery pole piece production equipment, in particular to an adsorption type pole piece guiding device. Background Art

[0002] In the production process of lithium battery pole pieces, it is necessary to coat the positive electrode active material or the negative electrode active material on the substrate (generally a metal foil film) to form the pole piece, and the pole piece needs to be baked in a baking oven. The baking ovens currently used basically adopt air-floating baking ovens, and the pole pieces are all in a floating state in the baking oven. When the tension on the left and right sides of the pole piece is uneven, or the width of the pole ears on the left and right sides of the pole piece is inconsistent, it is easy to cause the pole piece to deviate in the baking oven. In the prior art, when encountering such a situation, a deviation correction device located behind the baking oven is usually used to solve it. However, when the pole piece deviates seriously, the effect is poor.

[0003] The market needs a pole piece alignment device that can be flexibly installed in a baking oven to align the pole piece at any time. Utility Model Content

[0017] See also Figures 1 to 3 , Figures 1 to 3 The invention discloses an adsorption type electrode piece guiding device, comprising a vacuum adsorption box 1, a linear guide pair 2, a translation motor 3 and a position detection switch 4, wherein the vacuum adsorption box 1 is arranged on a slider 21 of the linear guide pair 2, and the translation motor 3 drives the slider 21 to reciprocate on a guide rail 22 of the linear guide pair 2 through a linear drive mechanism 5; the position detection switch 4 is arranged on the vacuum adsorption box 1, and the position detection switch 4 moves synchronously with the vacuum adsorption box 1. The utility model has the advantage of being installed in a baking oven, and being able to guide the electrode piece 10 when the electrode piece 10 needs to be guided.

[0018] Preferably, the vacuum adsorption box 1 includes a first clamping plate 11 and a second clamping plate 12 which are arranged in parallel at a predetermined distance, and a driving pulley 13 and a passive pulley 14 are respectively provided at both ends of the first clamping plate 11 and the second clamping plate 12, and a suction belt 15 with suction holes 151 is sleeved on the driving pulley 13 and the passive pulley 14, and a belt motor 16 is connected to one end of the driving pulley 13 through a coupling 17; when in use, after the suction belt 15 absorbs the pole piece 10, the belt motor 16 can drive the suction belt 15 to run synchronously with the running speed of the pole piece 10, so that the running stability of the pole piece 10 will not be affected; in this embodiment, the belt motor 16 can use a servo motor.

[0019] Preferably, the central axis of the vacuum adsorption box 1 or a line 110 parallel to the central axis forms an angle α of 0-20 degrees with the pole piece travel direction 120.
