Dispensing wiredrawing cleaning mechanism and dispensing mechanism

Abstract

The utility model provides a dispensing wiredrawing cleaning mechanism and a dispensing mechanism. The dispensing wiredrawing cleaning mechanism comprises a bottom plate, a sliding part, a sliding seat and a pushing driving part, the sliding piece comprises at least one sliding rail, a sliding block is arranged on the sliding rail in a sliding mode, and the sliding rail is fixed to the bottom plate. The sliding block is fixed on a sliding seat, the sliding seat is rotationally connected with a brush, and one end of the brush is in transmission connection with a rotation driving device for driving the brush to rotate; the pushing driving piece is fixed to the bottom plate and connected with the sliding base. The pushing driving piece is used for pushing the sliding base to move back and forth along the sliding rail. When the automatic glue dispensing device works, after glue dispensing is completed and the glue dispensing nozzle ascends to a glue wiping position, the push driving piece pushes the sliding seat to move forwards along the sliding rail, the rotary driving device drives the brush to rotate, and residual hot melt glue on the glue dispensing nozzle is wound on the brush, so that point explosion caused when a top cover is welded due to the fact that wiredrawing residual glue falls off is prevented, and poor welding of the top cover and an aluminum shell is prevented; and the welding yield of the top cover is ensured.

[0001] The utility model relates to the field of lithium ion battery production equipment, in particular to a glue dispensing wire drawing cleaning mechanism and a glue dispensing mechanism. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is intercalated and deintercalated between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

[0003] In the current adapter welding process, after the adapter and the top cover are welded, the dispensing mechanism rises after dispensing, and there will be wire drawing. After dispensing, it cannot be guaranteed that the hot melt adhesive can be 100% blown off, and the dispensing wire drawing will remain on the battery cell, affecting the poor welding of the top cover and the aluminum shell, affecting the welding quality of the top cover, etc. Utility Model Content

[0007] Preferably, the bottom plate is a flat plate, and a plurality of fixing holes are provided on the flat plate.

[0008] Preferably, there are two slide rails, which are symmetrically fixed on the base plate.

[0009] Preferably, two bearing seats are fixed on the slide seat, bearings are installed on the bearing seats, and both ends of the brush are sleeved in the inner ring of the bearing.

[0013] Preferably, the motor or the reduction motor is connected to one end of the brush via a bearing.

[0014] Preferably, the driving member is a pneumatic cylinder or an electric cylinder.

[0015] The utility model secondly proposes a glue dispensing mechanism, which comprises the glue dispensing wire drawing cleaning mechanism mentioned above.

[0016] Preferably, the glue dispensing mechanism further comprises a movable plate, on which at least one glue dispensing machine is mounted.

[0017] The beneficial effects of the utility model are as follows: during operation, after the dispensing is completed, the dispensing nozzle rises to the glue wiping position, and the driving part pushes the slide seat to move forward along the slide rail, the rotating driving device drives the brush to rotate, and the residual hot melt adhesive wire on the dispensing nozzle is entangled on the brush to prevent the residual adhesive from falling and causing explosion points during the welding of the top cover, thereby preventing poor welding between the top cover and the aluminum shell and ensuring the excellent welding rate of the top cover; the utility model can be directly installed on the existing dispensing mechanism through the bottom plate, and is suitable for different types of dispensing mechanisms, has good compatibility, does not require additional modification costs, is convenient to modify, and has low costs.
