Description

Pressure device

Technical Field

The application relates to the technical field of battery production, in particular to a pressure device.

Background

With the optimization of the lithium battery manufacturing process, large-sized battery cells are becoming more popular in the market. After lamination or winding, the battery core is usually subjected to cold and hot pressing treatment through a subsequent process, and in order to ensure the consistency of cold and hot pressing effects, the flatness requirements on the upper pressing plate and the lower pressing plate are higher, and the upper pressing plate and the lower pressing plate are generally designed into an integral structure. However, when the battery cells with large weight after cold and hot pressing are taken on a flat pressing plate, the battery cells cannot be effectively grabbed by the clamping jaw.

One of the solutions is to install a suction cup on the discharging claw hand so as to suck up the battery cell through the suction cup and transfer the position of the battery cell. However, the sucker can only aim at a lighter battery cell, and when the weight of the battery cell is large, the sucker cannot provide enough suction force to take away the battery cell, so that the battery cell has the limitation of use. When the suction force of the sucker is too large, the sucker mark is left on the pole piece to cause the damage of the pole piece, the suction force provided by the sucker is unstable, the battery cell is easy to fall and damage, and the quality of a finished product is influenced; in addition, the sucking disc is the wearing and tearing spare, needs periodic inspection to change, influences production efficiency.

The other solution is to adopt split type structure with cold, hot pressing hypoplastron, and cold, hot pressing hypoplastron includes the plate body and sets up the backup pad in the plate body middle part, backup pad and the setting of plate body components of a whole that can function independently to make the backup pad remove along vertical direction for the plate body, and the electric core is when shifting, jack-up support jack-up backup pad and the electric core that is in the backup pad top, and the rethread unloading claw hand takes away the electric core. This kind of design mode does can realize the removal of electric core, but split type hot pressing board can't guarantee the homogeneity of temperature, leads to backup pad position department electric core cold, hot pressing effect to have the difference, and has the clearance between backup pad and the plate body of split type cold, hot pressing board down, leads to the cold and hot pressing effect of clearance department electric core not ideal, influences the cold and hot pressing effect of electric core. In addition, under long-term state, the plane appears the difference in height easily between backup pad and the plate body, leads to electric core cold, hot pressing effect inconsistent to, in the use repeatedly, can appear wearing and tearing between backup pad and the plate body and produce the metal fillings, influence the electrical property of electric core.

Therefore, when the traditional cold and hot pressing device moves the battery cell, the battery cell is limited in use in a mode of grabbing the battery cell by using the sucker, and the battery cell is easy to damage, so that the effect of a finished product is affected; the lower pressing plate of the cold and hot pressing device is designed in a split type to influence the cold and hot pressing effect of the battery cell, and metal scraps are easy to generate in the use process to influence the electrical property of the battery cell.

the workpiece 5 is moved by the jaws 4 to above the jacking station 12, the jacking member 3 is lifted, and the end of the ram 312 passes through the through hole 13 and is supported at the bottom of the workpiece 5. The clamping jaw 4 is released, at this time, the ejector rod 312 provides a supporting force for the workpiece 5, and the jacking member 3 descends so that the workpiece 5 is supported at the jacking station 12 of the lower platen 1.

As shown in fig. 2, the second driving member 212 on the right pushes the workpiece 5 to move leftward by the adjusting lever 211 until the adjusting lever 211 on the right is retracted after the workpiece 5 is at the pressing station 11, at which time the lower platen 1 and the upper platen perform pressing operation on the workpiece 5 (the upper platen is raised after the upper platen is lowered to cool and heat press the workpiece 5).

As shown in fig. 1, the second driving member 212 on the left pushes the workpiece 5 to move rightward by the adjustment lever 211 until the adjustment lever 211 on the left is retracted after the workpiece 5 is at the jacking station 12.

As shown in fig. 4, the clamping jaw 4 hooks the bottom of the workpiece 5 so that the workpiece 5 can be supported by the clamping jaw 4. As shown in fig. 5, the ejector rod 312 is retracted, and the clamping jaw 4 drives the workpiece 5 to the next station.

Wherein, in the process of moving the workpiece 5 left and right on the lower pressing plate 1, the end part of the ejector rod 312 is 0.1mm lower than the surface of the lower pressing plate 1, so as to avoid the ejector rod 312 from damaging the workpiece 5 in the process of translating the workpiece 5 left and right. And when the workpiece 5 moves to the pressing station 11, the positioning device can be used for positioning the workpiece 5, so that the positioning accuracy of the workpiece 5 is ensured, and the contact between the probe and the current collector during the short circuit test of the workpiece 5 is facilitated. The workpiece 5 is positioned in a conventional manner, which is not described here too much.
