DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the application will be described below with reference to the drawings in the embodiments of the application.

[0026] Please refer to Figures 1-5 , the application provides a battery tab punching device with high punching precision, comprising a punching assembly 10 and a waste collecting assembly 20.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the punching assembly 10 comprises a base 110 and a frame 190, and the base 110 is fixedly installed at the top end of the frame 190. The base 110 is fixedly connected with a fixed vertical plate 130 and a fixed seat 170, respectively, and a feeding groove 111 is arranged between the fixed vertical plate 130 and the fixed seat 170 on the base 110. The lifting piece 120 is installed on the fixed vertical plate 130, and the lifting end of the lifting piece 120 is installed with a punching knife 160. The punching knife 160 is integrally formed with a guide block 161 on one side, and the guide block 161 is in contact with the side wall of the fixed seat 170 when the punching knife 160 is punching. When the battery tab is punched, the battery tab is placed on the fixed seat 170, and then the lifting piece 120 is started to make the punching knife 160 move downward. When the punching knife 160 moves downward, the guide block 161 first contacts the side wall of the fixed seat 170 downward, thereby realizing the punching of the battery tab, and the waste after punching falls through the feeding groove 111. By sliding the guide block 161 in contact with the side wall of the fixed seat 170, the cutting end burr of the battery tab is smooth when the punching knife 160 is cutting down, thereby improving the punching precision of the battery tab and making the punching effect of the battery tab good.

[0028] In this embodiment, the cutting edge end of the punching knife 160 is inclined. The cutting edge of the punching knife 160 is invasive, and since the battery tab is metal, the punching of the battery tab is more smooth and the cutting effect is good.

[0029] In the embodiment, the lifting section of the lifting piece 120 is fixedly connected with a tool holder 150, and a punching cutter 160 is installed on the tool holder 150. Specifically, the tool holder 150 is installed with a positioning piece 180 on the side away from the guide sliding block 141. The positioning piece 180 comprises an installation plate installed on the side of the tool holder 150 away from the guide sliding block 141, and a second air cylinder is installed on the installation plate. The cylinder rod end of the second air cylinder is movably penetrated through the installation plate and fixedly connected with a plastic pressing plate. The plastic pressing plate can press and position the battery tab on the fixing seat 170, facilitating the punching of the punching cutter 160. A guide piece 140 is arranged between the tool holder 150 and the fixed vertical plate 130. The guide piece 140 comprises a guide sliding block 141 and a guide sliding rail 142, which are arranged on the opposite surfaces of the tool holder 150 and the fixed vertical plate 130, respectively. The guide sliding block 141 is in sliding connection with the guide sliding rail 142. The lifting piece 120 comprises a first air cylinder 121 installed on the outside of the fixed vertical plate 130. The cylinder rod end of the first air cylinder 121 is fixedly connected with a lifting plate 122, and the tool holder 150 is fixedly connected with the lifting plate 122. When punching the battery tab, the second air cylinder is first started to press and fix the battery tab by the plastic pressing plate, and then the first air cylinder 121 is started to lower the lifting plate 122, so as to lower the punching cutter 160 to cut the battery tab. When the punching cutter 160 is lowered, the cooperation of the guide sliding block 141 and the guide sliding rail 142 makes the tool holder 150 more stable during movement and lifting, thereby improving the accuracy of punching the battery tab.

[0030] Please refer to Figure 1 and Figure 5 The waste collecting assembly 20 comprises a waste collecting bin 210, and a discharging baffle 220 is detachably inserted at the discharging opening of the waste collecting bin 210. Specifically, the bottom of the waste collecting bin 210 is provided with a supporting column. The waste generated by punching is collected in the waste collecting bin 210 through the discharging chute 111. The detachable connection of the discharging baffle 220 and the waste collecting bin 210 enables the waste in the waste collecting bin 210 to be uniformly or continuously collected, which can be determined by the production personnel according to the actual production situation.

[0031] In the embodiment, the discharging opening of the waste collecting bin 210 is provided with a slot 211 matched with the discharging baffle 220. The top end of the discharging baffle 220 is installed with a handle 230. When continuous collection of waste is needed, the handle 230 is gripped to take out the discharging baffle 220 from the waste collecting bin 210 through the slot 211, so that continuous discharging can be performed. When centralized discharging is needed, the handle 230 is gripped to insert the discharging baffle 220 into the waste collecting bin 210 through the slot 211 to block the discharging opening, and then the discharging baffle 220 is taken out when unified discharging is performed.

[0032] The working principle of the battery tab punching device with high punching precision is as follows: when the battery tab is punched, the battery tab is placed on the fixing seat 170, then the lifting piece 120 is started to move the punching knife 160 downward, when the punching knife 160 moves downward, the guide block 161 first contacts the side wall of the fixing seat 170 downward, thereby realizing the punching of the battery tab, and the waste after punching falls through the discharging groove 111. Through the sliding contact of the guide block 161 with the side wall of the fixing seat 170, the cutting end burr of the battery tab is smooth when the punching knife 160 is cut downward, thereby improving the punching precision of the battery tab and making the punching effect of the battery tab good. The waste produced by punching enters the inside of the waste collecting bin 210 through the discharging groove 111, and then is collected. Through the detachable connection of the discharging baffle 220 and the waste collecting bin 210, the waste inside the waste collecting bin 210 can be uniformly collected or continuously collected, which can be determined by the production personnel according to the actual production situation.

[0033] It should be noted that the specific model and specification of the first cylinder 121 and the second cylinder need to be selected and determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0034] The power supply of the first cylinder 121 and the second cylinder and its principle are clear to those skilled in the art, and will not be described in detail here.

[0035] The above only describes the embodiments of the present application and does not limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
