Problems solved by technology
[0004] However, the existing method is to roll the cutting edge at the opening position of the bottom cover to deform it and attach it to the step of the upper cover. However, due to the small size of the battery, the rolling force of the traditional rolling device is uneven, which is easy to cause Dimensional deviation and liquid leakage problems affect product quality, increase defective products, and increase costs

Embodiment Construction
[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

A battery capping and sealing machine, comprising a feeding device, a transfer device, and a capping and sealing device. The capping and sealing device includes: a bracket, a capping assembly, and a crimping and sealing assembly, and the crimping and sealing assembly includes a positioning jig , the lower pressing piece and the crimping and sealing pressure column, the crimping and sealing pressure column is provided with a channel, the lower pressing piece is used to drive the sealing pressure column to move towards the direction close to the battery, and the channel is used to accommodate The upper cover of the battery is placed, and the pressing slope is used to squeeze the cutting edge at the opening position of the bottom cover of the battery, so that the cutting edge at the opening position of the bottom cover of the battery is deformed by force, thereby making the battery The cutting edge at the opening position of the bottom cover is riveted on the step of the upper cover. The battery gland sealing machine provided by the present invention can ensure accurate sealing of batteries, avoid leakage of electrolyte, and ensure uniform thickness of batteries, thereby greatly improving battery yield and product quality.
Description
technical field [0001] The invention relates to the field of battery gland sealing equipment, in particular to a battery gland sealing machine. Background technique [0002] As we all know, in the battery preparation process, capping and sealing are extremely important links. In order to prevent electrolyte leakage, it is necessary to perform capping and sealing operations on the battery casing. For example, for batteries such as button batteries or cylindrical batteries that need to be sealed with a gland, the bottom cover needs to be riveted on the top cover. [0003] see figure 1 , which is a schematic diagram of the structure of the unpressed seal 20 of the button battery. Taking the button battery as an example for illustration, the cutting edge 21a at the opening position of the bottom cover 21 of the button battery is pressure riveted on the step 22a of the upper cover 22. Realize the crimping and sealing operation of the upper cover and the bottom cover, that is, r...
