In order to improve the automatic welding of the tab 100 device, the present application proposes a new automatic welding tab 100 device, please refer to FIG. 1 to FIG. 5, which shows an embodiment of the automatic welding tab 100 device of the present application. Schematic.

The automatic welding tab 100 device comprises a fixing base 1, a mounting plate 2, a pole unwinding mechanism 3, a tab press mechanism 4, a tab cutting mechanism 5, a tab welding mechanism 6, and a tab correcting mechanism 7; The mounting plate 2 is slidably mounted on the fixing base 1; the polar ear unwinding mechanism 3 is fixedly mounted on the mounting plate 2; the tab pressure feeding mechanism 4 for pulling the tab 100 is disposed on the mounting plate 2; The tab cutting mechanism 5 of the tab 100 is disposed on the mounting board 2 and behind the tab press mechanism 4; the tab welding mechanism 6 for soldering the tab 100 to the pole piece 300 is disposed on the mounting board 2 and behind the tab cutting mechanism 5; a tab correcting mechanism 7 for correcting the position of the tab 100 on the pole piece 300, the tab correcting mechanism 7 comprising means for detecting the tab 100 on the pole piece 300 a position detecting feedback component 71 and a correcting execution component 72 for driving the movement of the mounting plate 2, the detecting feedback component 71 is disposed on the mounting plate 2 and adjacent to one side of the tab cutting mechanism 5, and the correcting execution component 72 is disposed on the fixing seat 1 on.

Referring to Figure 3, the action of the automatic welding tab 100 device automatically welds the tab 100 to the pole piece 300; wherein, in the welding position of the tab welding mechanism 6, a pole piece 300 transport mechanism is provided, the pole piece 300 transport mechanism including Two rollers 200 for conveying the pole piece 300. When the pole piece 300 is transferred to the welding position, the two rollers 200 stop working. At this time, when the welding work of the tab 100 is started, after the tab 100 is welded to the pole piece 300, the two rollers 200 start to rotate, and the pole piece 300 is rotated. After being transferred to the next station for subsequent processing, the automatic welding tab 100 device waits for the next piece of the pole piece 300 to be processed, so that the circulating water operation is performed, the pole piece 300 transmits the same distance each time, and the waiting time is also stopped each time. the same.

The tab correction mechanism 7 is mainly used to perform "torque 100 rectification" on the position of the tab 100 that is initially fed relative to the pole piece 300. In order to more clearly illustrate the embodiments of the present application, the "polar ear 100 correction" is now explained. The term "polar ear 100 correction" means that the pole piece 300 is transferred between the two rollers 200. Ideally, the two rollers 200 simultaneously tension the pole piece 300, so that the pole piece 300 is in a smooth and flat state. In order to ensure that the tab 100 is accurately soldered to the pole piece 300, but the pole piece 300 is not completely in tension, which is prone to breakage, so that the pole piece 300 sometimes slightly slides on the roller 200, and may In the case of wrinkles, if the wrinkles are just the place of welding, this is not suitable for the welding of the ear 100. At this time, the position of the tab 100 needs to be re-adjusted, and only a smooth and flat place can be found to ensure the welding success. Therefore, it is necessary to correct the welding position of the tab 100 in time according to the current flatness of the pole piece 300, which is called rectification.

The working principle of the ear correction mechanism 7 is: a detection feedback component 71 is disposed near the welding of the tab 100, and the data on the pole piece 300 is detected and collected, and then the data is fed back to the correction performing component 72 for data processing, and then The correcting execution component 72 drives the mounting plate 2 to move according to the result of the data, thereby adjusting the position on the pole 100 pole piece 300 for the purpose of correcting the deviation.

The detection feedback component 71 includes a first guiding rod 711, two clamping blocks 712, a photoelectric sensor 713, and a dial gauge 714. The first guiding rod 711 is fixedly mounted on the mounting board 2, and the two clamping blocks 712 are spaced apart from each other. On the first guiding rod 711, the photoelectric sensor 713 is disposed on a clamping block 712 for determining the position of the tab 100 on the pole piece 300, and feeding back the detection data to the correcting execution component 72; the dial gauge 714 is set. On the other clamping block 712, the detection position of the photosensor 713 is adjusted. Specifically, in an embodiment of the present application, the photosensor 713 projects an inductive light beam of a certain area on a surface of the pole piece 300 corresponding to the position of the tab 100, and blocks the light beam in the sensing area through the pole piece 300. The case is to judge whether or not the pole piece 300 of the region is wrinkled. For example, the photosensor 713 projects a rectangular induced beam toward the surface of the pole piece 300 corresponding to the position of the tab 100. If the detected area of the pole piece 300 completely blocks the induced beam, it proves that the area is suitable for soldering, photoelectric sensing. The device 713 feeds back the detection data to the console, and controls the tab welding mechanism 6 to solder the tab 100; if the area detected by the pole piece 300 does not completely cover the inductive beam, it proves that there is wrinkles in the area, and the photoelectric sensor 713 will feed back the detection data to the correcting execution component 72 to drive the mounting plate 2 to move. At this time, the photoelectric sensor 713 will also move along with the mounting plate 2, and re-select a new area for detection; until the appropriate area is detected, the mounting board 2 is stopped, the tab 100 is in the area, and then the detection data is fed back to the console, and the tab welding mechanism 6 is controlled to weld the tab 100. Of course, the position of the photosensor 713 can be adjusted by the dial gauge 714 as a reference according to actual needs, thereby adjusting the relative distance between the photosensor 713 and the tab 100; and also by the tilt angle of the clamping block 712. The area of the inductive light velocity projection area of the photosensor 713 on the pole piece 300 is adjusted.

The front and rear and left and right dimensions of the mounting plate 2 are moved by the ball screw to ensure that the range of the correction of the ear 100 can be maximized, thereby improving the success rate of the automatic welding of the ear 100.

The technical solution of the present application realizes one or more corrections of the tab 100 before soldering by adding the tab correction mechanism 7 to the device to detect the pole piece 300, thereby achieving accurate and fast orientation of the tab 100.
