Embodiment Construction
[0031] 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, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0032] 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 ...

The invention relates to a laser welding and detection device for batteries. A feeding mechanical hand can sort batteries, to be welded on a feeding process line, to a welding jig; a welding head andthe welding jig are moved to a welding station to complete the welding; after the welding is completed, a welding discharging mechanism sorts the batteries to a bearing platform and the appearance detection is completed at an appearance detection station so as to determine whether there are defects such as explosion points and intermittent welding; further, the batteries subjuected to the appearance detection are sorted to a roller press by a detection discharging mechanism to realize flanging and flattening; the batteries subjected to roller pressing are sorted to a detection jig by a rollerpress discharging mechanism and whether the flanging thickness of the batteries is qualified is detected through a contour detector; finally, the batteries which has been welded and are qualified in appearance detection and contour detection can be sorted to a good-product discharging process line by a discharing mechanical hand, and the other batteries are sorted to a waste-product discharging process line. Since the above welding, appearance detection, roller pressing and contour detection are all completed automatically, the welding efficiency of top covers of the batteries is improved effectively.
Description
technical field [0001] The invention relates to the technical field of laser processing equipment, in particular to a battery laser welding and detection device. Background technique [0002] In the battery production process, an important link is to weld the top cover to the battery case to seal the battery. The general process of welding the top cover is: fix the shell with the top cover pre-fixed in the fixture, and then weld it with a laser welder. Since there may be defects such as explosive points, broken welds, and inconsistent welds at the welding place, the appearance of the battery needs to be inspected after welding. In addition, the top cover and the shell are provided with flanges to ensure welding. After the welding is completed, the flanges need to be flattened to ensure that the appearance of the weld seam is within a reasonable range. [0003] At present, the common practice is that after the top cover is welded, the operator takes the battery under the co...
