[0026] Reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4The application discloses a battery aluminum plastic film cutting device. The battery aluminum plastic film cutting device comprises a base 1, a distance adjusting platform 2 and a cutting mechanism 3. In some embodiments, the distance adjusting platform 2 is assembled on the base 1 and can move relative to the base 1. The cutting mechanism 3 is assembled on the distance adjusting platform 2 and can move with the distance adjusting platform 2 to adjust the cutting position of the battery aluminum plastic film. Preferably, the distance adjusting platform 2 moves relative to the base 1 to drive the cutting mechanism 3 to move synchronously with the distance adjusting platform 2, so as to adjust the cutting position of the cutting mechanism 3 on the battery aluminum plastic film, to meet different requirements of actual production, without adding or replacing a cutting knife, so that the battery aluminum plastic film can be cut in different widths, the cutting process is optimized, and the production efficiency is improved.
[0027] Referring to Figure 1 、 Figure 2 and Figure 4 In some embodiments, the base 1 is provided with a distance adjusting driving element 11, and an output shaft of the distance adjusting driving element 11 is connected with the distance adjusting platform 2. Optionally, the distance adjusting driving element 11 can be one or more of electric devices such as a cylinder, a linear motor and an electric screw rod, that is, the distance adjusting platform 2 is driven to move by the distance adjusting driving element 11 composed of electric devices. Optionally, the distance adjusting driving element 11 can be a manual device such as a handle, that is, the distance adjusting platform 2 is driven to move by a worker manually operating the handle. Optionally, the distance adjusting driving element 11 can be assembled at any position of the base 1. In the embodiment, the distance adjusting driving element 11 is preferably arranged at one end of the base 1 away from a battery placing area, so as to prevent the distance adjusting platform 2 and / or the cutting mechanism 3 from interfering with the distance adjusting driving element 11. Preferably, the distance adjusting driving element 11 comprises a distance adjusting cylinder, and an output shaft of the distance adjusting cylinder is connected with the distance adjusting platform 2. In this way, the distance adjusting platform 2 drives the cutting mechanism 3 to move by the distance adjusting cylinder, so as to adjust the cutting position of the cutting mechanism 3 on the battery aluminum plastic film, to meet different requirements of actual production.
[0028] Referring to Figure 1 、 Figure 2 and Figure 4In some embodiments, the base 1 is equipped with a distance-adjusting slide rail 12, the distance-adjusting slide rail 12 is slidingly connected with a distance-adjusting slide block 13, and the distance-adjusting platform 2 is equipped on the distance-adjusting slide block 13. In this way, the direct sliding friction between the distance-adjusting platform 2 and the base 1 during movement can be prevented, the equipment wear can be effectively avoided, and the movement track of the distance-adjusting slide block 13 can be limited by the distance-adjusting slide rail 12, so as to limit the movement track of the distance-adjusting platform 2. In the embodiment, the distance-adjusting slide rail 12 is arranged between the distance-adjusting driving member 11 and the battery, and the distance-adjusting slide rail 12 is arranged in a straight manner. When the distance-adjusting driving member 11 drives the distance-adjusting platform 2 to move together with the cutting mechanism 3, the distance-adjusting platform 2 slides along the distance-adjusting slide rail 12 through the distance-adjusting slide block 13, so as to prevent the direct sliding friction between the distance-adjusting platform 2 and the base 1 during movement, limit the movement track of the distance-adjusting platform 2, and enable the cutting mechanism 3 to move in a straight line, so as to effectively adjust the cutting position of the cutting mechanism 3 on the aluminum-plastic film of the battery.
[0029] Referring to Figure 1 and Figure 2 In some embodiments, the base 1 is equipped with two limiting members 4, the two limiting members 4 are arranged in a spaced manner in the movement direction of the distance-adjusting platform 2, and the distance-adjusting platform 2 is limited between the two limiting members 4. In the embodiment, the movement direction of the distance-adjusting platform 2 is defined as the front-back direction, any one of the limiting members 4 is located in front of the distance-adjusting platform 2, so as to limit the limit position of the forward movement of the distance-adjusting platform 2 relative to the base 1, and the other limiting member 4 is located behind the distance-adjusting platform 2, so as to limit the limit position of the backward movement of the distance-adjusting platform 2 relative to the base 1. Optionally, the battery is placed in front of the distance-adjusting platform 2, and the distance-adjusting driving member 11 is arranged behind the distance-adjusting platform 2. In this way, the limit position defined by the limiting member 4 in front prevents the distance-adjusting platform 2 from moving forward excessively, so as to effectively reserve a certain width of the aluminum-plastic film, so as to meet the requirements of packaging and battery performance, and the limit position defined by the limiting member 4 behind prevents the distance-adjusting platform 2 from moving backward excessively, so as to avoid the mutual interference between the distance-adjusting platform 2 and the distance-adjusting driving member 11, and the collision damage of the equipment.

Preferably, by driving the telescopic rod 42 to be telescoped away from or close to the distance adjusting platform 2, the limiting positions of the limiting block 22 in front and behind are adjusted, so as to change the distance of the distance adjusting platform 2 in front and behind, and further adjust the cutting position of the cutting mechanism 3 on the battery aluminum plastic film. Further, one end of the telescopic rod 42 close to the distance adjusting platform 2 is provided with a buffer block, which buffers the collision between the limiting block 22 and the telescopic rod 42, so as to prevent the components from being damaged by the collision.
