Description

Technical Field

[0001] This utility model relates to the field of spot welding technology, specifically to an automatic spot welding machine for button battery electrodes. Background Technology

[0002] In the production process of button batteries, positive and negative electrode plates need to be welded. Most of the existing welding equipment is spot welding, which uses spot welding machines. The structure of a spot welding machine is very simple. It is a high-power transformer that converts 220V AC power into a low-voltage, high-current power supply, which can be either DC or AC.

[0003] Existing button battery spot welding equipment is mostly manual. A person holds the workpiece, places it on the welding head of the welding machine, and then turns on the welding switch. This process is prone to workpiece displacement, resulting in inaccurate welding and inconsistent weld quality. Manual operation is labor-intensive and poses certain risks. Furthermore, the numerous steps involved lead to high manpower requirements and low production efficiency. Some controlled spot welding machines also exist, but they mostly use a single working point method. After welding the positive electrode on one machine, the worker manually transfers the battery to another machine to weld the negative electrode, followed by manual voltage testing. This method is also inefficient. Utility Model Content

The battery conveyor 22 is mounted on the vibrating feeder 21, and the vibrating feeder 21 drives the battery conveyor 22 to vibrate and feed the button batteries forward. The battery lateral movement module 24 is mounted on the battery feeding rack 23, and the battery lifting module 25 is mounted on the drive element of the battery lateral movement device and is reciprocated laterally by the battery lateral movement device. The battery synchronization plate 26 is movably mounted on the drive element via a lifting slide rail and is driven by the battery lifting module 25 to perform lifting and lowering actions. The two suction nozzles 27 are symmetrically arranged on both sides of the battery synchronization plate 26. One suction nozzle 27 places the button battery on the battery conveyor 22 onto the loading seat 28, while the other suction nozzle 27 simultaneously places the button battery on the loading seat 28 onto the synchronous belt circulation mechanism 3.

[0029] The synchronous belt circulation mechanism 3 includes a base plate 31, a main frame 32, side frames 33, a drive wheel 34, a driven wheel 35, a conveyor belt 36, a battery fixture 37, a fixture positioning device 38, an electrode positioning device 39, and a drive device 310. Several main frames 32 are arranged sequentially along the long side of the base plate 31. Two guide rails 312 are mounted on the main frames 32. Specifically, the upper sides of the main frame 32 symmetrically protrude upwards to form two support arms. The two guide rails 312 are correspondingly mounted on the two support arms, and a guide groove is formed between the two guide rails 312 for the conveyor belt 36 to pass through. The guide rails in the same straight direction are connected. A slot is provided in the lower middle part of the main frame 32 for the conveyor belt 36 to pass through, facilitating the passage of the conveyor belt 36 and the battery fixture 37. A sliding strip is provided on the base plate 31 at the position corresponding to the slot. The sliding strip supports the battery fixture 37, preventing the conveyor belt 36 from sagging due to the weight of the battery fixture 37.

[0030] The driving wheel 34 and driven wheel 35 are disposed at both ends of the base plate 31. The conveyor belt 36 passes around the guide rail, driving wheel 34, and driven wheel 35. A plurality of battery fixtures 37 are disposed on the conveyor belt 36. The drive device 310 is disposed on the base plate 31 and can drive the driving wheel 34 to rotate.

When positioning is required, as the battery fixture 37 moves to the predetermined position with the conveyor belt 36, the positioning cylinder extends, and the space between the two positioning claws precisely clamps and positions the battery fixture 37.

[0033] The electrode positioning device 39 includes a lifting and positioning cylinder, a finger cylinder, and positioning blocks. The finger cylinder is mounted on the driving element of the lifting and positioning cylinder, and the two positioning blocks are correspondingly mounted on the two fingers of the finger cylinder. When the positive or negative electrode is placed on the button cell of the battery fixture 37, the lifting and positioning cylinder drives the finger cylinder to descend to a predetermined height. The finger cylinder controls the two positioning blocks to move closer together to position the positive or negative electrode on the button cell, preventing displacement and ensuring the welding effect.

[0034] When the synchronous belt circulation mechanism 3 is working, the drive device 310 drives the drive wheel 34 to rotate, which in turn drives the battery fixture 37 to transport the button battery forward through the operation of the conveyor belt 36. When the battery fixture 37 moves to the required processing position, the positioning cylinder extends and clamps and positions the battery fixture 37 precisely through the gap between the two positioning claws. When it is necessary to spot weld the positive or negative electrode, the lifting positioning cylinder drives the finger cylinder to descend to the height of the upper surface of the button battery. The finger cylinder controls the two positioning blocks to move closer together to position the positive or negative electrode on the button battery, preventing displacement, and waiting for the spot welding machine to weld, thus avoiding displacement during welding.
