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...

Abstract

A battery gland sealing machine comprises a feeding device, a transfer device and a gland sealing device. The gland sealing device comprises a support, a gland assembly and a crimping sealing assembly, the crimping sealing assembly comprises a positioning tool, a press-down member and a crimping sealing press column, the crimping sealing press column is provided with a channel, the press-down member drives the sealing press column to move towards a battery, the channel is used to accommodate an upper cover of the battery, a pressing inclined surface is used to extrude a cutting edge in an opening position of a bottom cover of the battery so that the cutting edge is deformed by bearing a force, and further the cutting edge is pressed and pivoted onto a step of the upper cover. The battery gland sealing machine can ensure that the battery is sealed accurately, avoids an electrolyte from leakage, ensures that the battery thickness is uniform, and improves the battery yield rate and the 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...
