Obviously, the drawings described below are only part of the embodiments of the present application, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative labor.

[0011] Figure 1 This is a schematic diagram of the structure of the tab debris guide plate of an embodiment of the present application. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0013] Example

[0014] In order to solve the above technical problems, this embodiment provides a tab debris guide plate, such as Figure 1As shown, it includes a limit plate 10 and a guide block 20 arranged at the bottom of the limit plate 10, a guide groove is opened inside the guide block 20, and a positioning groove 30 for the pole ear to pass through is opened in the limit plate 10. The limit plate 10 is installed on the workstation of the tablet making machine for conveying the pole ear. The pole ear is cut by the tablet making machine after passing through the positioning groove 30, wherein the positioning groove 30 extends in the horizontal direction and is located above the guide block 20, so that the debris of the pole ear after cutting falls into the guide groove of the guide block 20, and the end of the guide block 20 away from the positioning groove 30 is conical, and then the pole ear debris is guided and collected through the guide groove of the guide block 20, so as to prevent the pole ear debris from flying randomly, facilitate collection and cleaning, and at the same time prevent the debris from falling onto the pole sheet, causing quality problems and safety risks of the finished battery.

[0015] Specifically, the positioning groove 30 extends to one side of the limiting plate 10, and the limiting plate 10 is formed with a flared opening 31 at one end of the positioning groove 30. When installing the limiting plate 10, the pole ear needs to be adjusted to pass through the middle of the positioning groove 30. By extending the positioning groove 30 to one side of the limiting plate 10 and opening the flared opening 31 on the side, it is convenient to adjust the installation position of the limiting plate 10 according to the conveying position of the pole ear. In some embodiments, when the pole ear passes through the positioning groove 30, the pole ear can be grasped and pulled by the clamping mechanism of the film making machine, and then the pole ear can be cut by the cutting mechanism of the film making machine, and then transferred and welded to the pole piece.

[0016] Furthermore, the limiting plate 10 is provided with a mounting slot 11 below the positioning slot 30, and the limiting plate 10 can be mounted on the tablet machine through the mounting slot 11 with height adjustment. Exemplarily, a bolt is inserted through the mounting slot 11, and the bolt is fixedly connected to the tablet machine, so that the height position of the limiting plate 10 on the tablet machine can be adjusted to ensure that the tab can pass through the positioning slot 30. In the process of conveying the tab, the tab may be deflected or slightly warped, thereby affecting the welding of the tab. Therefore, in this solution, the size of the positioning slot 30 can be designed to match the tab, and then when the tab passes through the positioning slot 30, the positioning slot 30 can play a role in positioning the tab, thereby avoiding the situation where the tab is deflected or warped during conveying.

[0017] In the above solution, baffles 40 are provided on both sides of the limiting plate 10, thereby preventing the tab debris from flying off from both sides, so that the debris can fall into the guide groove of the guide block 20, thereby realizing waste collection.

[0018] Specifically, the bottom surface of the guide block 20 is open, and a collection box is provided below the guide block 20. After the tab debris falls into the guide groove, the debris is guided by the guide groove to fall into the collection box, thereby facilitating the processing of the debris waste.

[0019] Furthermore, for the convenience of processing, the guide block 20 is integrally formed with the limit plate 10. Alternatively, in other embodiments, the guide block 20 is separately provided from the limit plate 10, and the guide block 20 is detachably connected to the limit plate 10 by screws. Furthermore, when the guide block 20 is separately provided from the limit plate 10, the bottom surface of the guide block 20 is closed, and thus there is no need to provide a collection box under the guide block 20, and the tab debris is collected through the guide groove of the guide block 20, and when it is full, the guide block 20 is removed to achieve the purpose of cleaning.

[0020] To summarize, the present application scheme arranges a limit plate on the tablet making machine, arranges a guide block at the bottom of the limit plate, a guide groove is opened inside the guide block, and a positioning groove for the pole ear to pass through is opened on the limit plate. The limit plate is installed on the work station of the tablet making machine for conveying the pole ear. The pole ear is cut by the tablet making machine after passing through the positioning groove. The positioning groove extends in the horizontal direction and is located above the guide block, so that the debris of the pole ear after cutting falls into the guide groove of the guide block. The end of the guide block away from the positioning groove is conical, and the pole ear debris can be guided and collected through the guide groove of the guide block, so as to prevent the pole ear debris from flying around, facilitate collection and cleaning, and at the same time prevent the debris from falling onto the pole piece, causing quality problems and safety risks in the finished battery.

[0021] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
