Problems solved by technology

It can be seen from this that the forming process of the general battery bus bar is as follows: firstly put the battery cell (plate group) into the fixture for fixing, and use a casting welding mold to form a bus bar (including the positive bus bar) on the tab of the battery cell. and negative busbar), and then manually weld the positive busbar and negative busbar between adjacent battery cells. The process of manually welding battery cells will lengthen the battery production cycle and reduce production efficiency.

Embodiment 1

[0022] refer to figure 1 , 2 , a core-pulling device for forming battery busbars, comprising a support frame 1, a core-pulling mechanism, and an ejection mold 2, the support frame 1 is provided with an accommodating groove 10 for fixing a battery case, the The core-pulling mechanism includes a slider 4 and a core-pulling 8 arranged on the slider 4, the slider 4 is installed on the outer wall of the support bracket 1, and the two ends of the slider 4 are provided with axially protruding bosses 41 , the ejector die 2 is provided with an ejector pin 21 corresponding to the boss 41, and the upper end of the ejector pin 21 has a guiding slope 211. Drive slide block 4 to pull out core-pulling 8.

[0023] The slider 4 is connected to the support bracket 1 through the screw 5, the slider 4 can slide along the screw 5, but to realize the sliding of the slider 4, the installation method includes but not limited to the screw 5 connection, and the optical axis can also be used. structu...

Embodiment 2

[0031] refer to image 3 , the difference between this embodiment and Embodiment 1 is that the battery product is different, only two opposite sliders 4 need to be provided on the support bracket 1, and the two ends of each slider 4 are provided with axially protruding protrusions. Column 41, ejector pins are set at the four end corners of the ejection mold, and only one guiding inclined plane needs to be formed on the upper ends of the ejector pins.

[0032] The working principle of the core-pulling device has been disclosed in the applicant's previous patent application, and will not be described in detail here.

Abstract

The invention discloses a core pulling device for storage battery bus-bar molding. The core pulling device for storage battery bus-bar molding comprises a bearing support, a core pulling mechanism and an ejection mould, wherein an accommodation groove which is used for fixing a storage battery shell is formed on the bearing support, the core pulling mechanism comprises a sliding block and a loose core arranged on the sliding block, the sliding block is arranged on the external lateral wall of the bearing support, and protruding columns which protrude axially are arranged at the two ends of the sliding block. Thimbles corresponding to the protruding columns are arranged on the ejection mould, guide slopes are arranged on the upper end portions of the thimbles, the ejection mould drives the thimbles to be inserted into the core pulling mechanism, and the thimbles drive the sliding block to pull the loose core out by pushing the protruding columns. The core pulling device for storage battery bus-bar molding is used for free of gap bridge welding of the storage battery bus-bar.

Description

【Technical field】 [0001] The invention relates to a device for casting and forming battery busbars, in particular to a device for realizing bridge-free welding of battery busbars by using core pulling. 【Background technique】 [0002] Battery is a kind of battery, its function is to store limited electric energy and use it in a suitable place, especially lead-acid battery has been widely used in power generation, lighting, transportation and other fields. A general battery has multiple battery cells that work independently, and multiple battery cells need to be connected by welding to form a complete battery group; in order to facilitate welding, a special fixture is required to fix multiple battery cells on the A certain shape, and then welded. It can be seen from this that the forming process of the general battery bus bar is as follows: firstly put the battery cell (plate group) into the fixture for fixing, and use a casting welding mold to form a bus bar (including the p...
