Description

Supporting mechanism, unreeling supporting device and laser processing system

Technical Field

The utility model relates to the technical field of automatic equipment, in particular to a supporting mechanism, an unreeling supporting device and a laser processing system.

Background

The lithium battery is widely applied to the fields of consumer electronics and electric automobiles due to the advantages of high energy density, long service life, green pollution-free performance, high safety performance and the like. With the continuous development of the battery industry, current collectors with better performance, namely composite current collectors formed by compounding polymers and metals, are appeared. The composite current collector can reduce the temperature rise of the battery, reduce the occurrence risk of thermal runaway and improve the safety of the battery.

In the production process of lithium batteries, a current collector is coated and dried to form a coil stock, and the coil stock needs to be die-cut into a specific shape to be used for battery production. Current technologies for current collector die cutting mainly include direct blade die cutting and laser die cutting. The direct die cutting of the blade is to cut into a required shape by means of a die directly using a cutter, and is divided into two types: (1) Cutting by a wood plate cutting die, and arranging a sharp cutting edge on the wood plate to enable the cutting edge to cut the pole piece under the action of certain pressure; (2) And (3) punching the hardware die, and cutting the pole piece by utilizing a very small gap between the punch and the lower cutting die. However, the cutter abrasion problem exists in the direct die cutting of the blade, the cutter tightness state is different during personnel assembly, the die cutting process is easy to be unstable, the cutting quality of the pole piece is poor, the battery performance is reduced, the management of the cutter is complicated, and the repair cost is high. For the above reasons, laser die cutting technology is increasingly being adopted.

The principle of laser die cutting is to irradiate the cut battery pole piece or current collector with high power density laser beam to heat the pole piece or current collector to high temperature to melt, vaporize, ablate or reach burning point to form hole, and the hole forms narrow slit continuously with the movement of the laser beam on the pole piece to complete the cutting of the pole piece.

The unwinding mechanism of the laser die cutting machine is often cantilever type, when the material is overweight, the deformation of a cantilever shaft of the unwinding mechanism can be increased, the unwinding resistance is increased, and the service life of a bearing at the unwinding shaft is reduced. Therefore, in the prior art, a supporting mechanism is proposed, wherein a supporting plate is directly driven to lift by an air cylinder, and when the air cylinder drives the supporting plate to rise to a preset height, a cantilever shaft of the unreeling mechanism is supported by the supporting plate. However, such a supporting mechanism requires a large supporting force for the cylinder, resulting in a large bore of the cylinder, taking up a large space and increasing the cost of the supporting mechanism.

Accordingly, improvements to existing support mechanisms are needed to reduce the size and cost of the support mechanism.

Referring to fig. 1 and 2, fig. 1 is a front view of a supporting mechanism 100 in the embodiment of the present utility model, fig. 2 is a schematic perspective view of the supporting mechanism 100 in the embodiment of the present utility model, and this embodiment provides a supporting mechanism 100, including a fixing frame 110, a sliding rail 120 and a supporting block 130, where the sliding rail 120 is disposed on the fixing frame 110, the supporting block 130 is slidably connected with the sliding rail 120, and further includes a first swing link 140 and a first connecting rod 150, a first joint of the first swing link 140 is rotatably connected with the fixing frame 110, a first joint of the first connecting rod 150 is rotatably connected with the supporting block 130, a second joint of the first swing link 140 is hinged with a second joint of the first connecting rod 150, and a rotation axis of the first joint of the first connecting rod 150, a rotation axis of the first joint of the first swing link 140 and a rotation axis between the first swing link 140 and the first connecting rod 150 are parallel to each other, and a driving component 160 driving the second joint of the first swing link 140 to rotate around the first joint, and a driving component 160 driving the second joint of the first swing link 140 to swing link 140 is disposed between the first joint of the first swing link 140 and the first connecting rod 150 extends parallel to the first joint 150.

Since the first joint of the first swing link 140 is rotatably connected to the fixing frame 110, the first joint of the first link 150 is rotatably connected to the supporting block 130, and the second joint of the first swing link 140 is hinged to the second joint of the first link 150, and the rotation axis of the first joint of the first link 150, the rotation axis of the first joint of the first swing link 140 and the hinge axis between the first swing link 140 and the first link 150 are parallel to each other, and the connection line between the first joint of the first swing link 140 and the first joint of the first link 150 intersects with the swing locus of the second joint of the first swing link 140, therefore, when the interval between the rotation axis of the first joint of the first swing link 140 and the rotation axis of the second joint is the sum of the interval between the rotation axis of the first joint of the first link 150 and the rotation axis of the second joint, at a maximum distance equal to the line of rotation of the first joint of the first oscillating bar 140 and the second joint of the first link 150, the force acting on the supporting block 130 will be transmitted through the first link 150 to the first oscillating bar 140, from the first joint of the first oscillating bar 140 to the fixed frame 110, since the first link 150 is now co-linear with the first oscillating bar 140 and the first link 150 is at an angle of 180 ° to the first oscillating bar 140, the force acting on the supporting block 130 will be transmitted by the first link 150 to the first oscillating bar 140 for the most part, by the first oscillating bar 140 to the fixed frame 110 for the most part, instead of to the driving assembly 160, and at this time the supporting block 130 is in contact with the supported element (cantilever shaft of the unreeling mechanism), and therefore, the force exerted by the support member on the support block 130 will be transmitted to the mount 110 for the most part rather than to the drive assembly 160, thus requiring less drive force on the drive assembly 160 and reducing the volume and cost of the drive assembly 160.
