[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings. Figure 1As shown, a tab coil cutting mechanism 10 includes: a coil loading device 100, a cutting and separating device 200 and a cutting linkage device 300, the coil loading device 100 includes a unwinding component 110 and a feeding module 120, the unwinding component 110 is arranged on one side of the feeding module 120, and the unwinding component 110 is used to unwind the tab coil onto the feeding module 120; the cutting and separating device 200 includes a separating module 210 and an adsorbent 220, the separating module 210 is arranged at the discharge end of the feeding module 120, and the adsorbent 220 is arranged on the separating module 210 The adsorption part 220 is used to adsorb and fix the tab coil at the discharge end of the feeding module 120; the cutting linkage device 300 includes a cutter 310 and a linkage module 320. The cutter 310 is arranged between the separation module 210 and the feeding module 120. The linkage module 320 is connected to the cutter 310 and the separation module 210 respectively. The linkage module 320 is used to drive the cutter 310 to move up and down toward the discharge end of the feeding module 120. The linkage module 320 is also used to drive the separation module 210 to perform reciprocating displacement toward or away from the discharge end of the feeding module 120.

[0024] It should be noted that the tab coil is unwound by the unwinding assembly 110 so that the tab coil can be loaded onto the feeding module 120. In this embodiment, the unwinding assembly 110 is a unwinding disc structure, so that the tab coil can be unwound by the cooperation of the unwinding disc and each roller group. After the tab coil is loaded onto the feeding module 120, the feeding module 120 cooperates with the unwinding operation of the unwinding assembly 110 to feed the tab coil, so that the tab coil is fed to the cutting and separation device 200, and then the tab coil is adsorbed and fixed by the adsorption component 220 on the separation module 210, and finally, the separation module 210 is moved away from the discharge end of the feeding module 120 to extend one end of the tab coil and fix it on the cutting and separation device 200. At this time, the cutter 310 is located between the adsorption component 220 and the discharge end of the feeding module 120. In this way, the cutter 310 can be driven by the linkage module 320 to press downward in the direction close to the discharge end of the feeding module 120, so that the tab coil located at the discharge end of the feeding module 120 is cut, thereby completing the cutting operation of the tab coil. The tab coil cutting mechanism 10 of the present invention is equipped with a coil feeding device 100, a cutting and separating device 200 and a cutting linkage device 300, so that the tab coil can be cut in an alternative manner to manual labor, thereby improving the efficiency and continuity of production and processing, and improving the overall production and processing quality.

[0025] Combine Figure 2 and Figure 3As shown, in one embodiment, the feeding module 120 includes a feeding table 121, a feeding roller group 122 and a feeding drive 123. The feeding table 121 is arranged on one side of the unwinding component 110. A feeding guide groove 121a is opened on the feeding table 121. The feeding roller group 122 is arranged in the feeding guide groove 121a. The feeding drive 123 is connected to the feeding roller group 122. The feeding drive 123 is used to drive the feeding roller group 122 to rotate relative to the feeding table 121.

[0026] It should be noted that the unwinding assembly 110 unwinds the tab coil into the feed guide groove 121a of the feed table 121. A pressure plate structure 124 is provided above the feed guide groove 121a, thereby limiting the tab coil in the feed guide groove 121a. At this time, the feed roller assembly 122 is driven to rotate by the feed drive 123, thereby driving the tab coil along the feed guide groove 121a for feeding and moving. In this embodiment, the feed roller assembly 122 is composed of a plurality of feed rollers, each of which is spaced apart in the feed guide groove 121a. The feed drive 123 is composed of a motor, a synchronous belt, and a drive shaft. By mounting each feed roller on a corresponding drive shaft, and then driving the synchronous belt and drive shaft to rotate by the motor, each feed roller can rotate relative to the feed table 121, thereby achieving the feeding operation of the tab coil.

[0027] In one embodiment, please refer to Figure 2 The feeding module 120 also includes a feeding pressure block 125 and a feeding pressure block driving component 126. The feeding pressure block 125 is arranged above the feeding guide groove 121a. The feeding pressure block driving component 126 is connected to the feeding pressure block 125. The feeding pressure block driving component 126 is used to drive the feeding pressure block 125 to perform reciprocating displacement in the direction of the feeding guide groove 121a.

[0028] It should be noted that when the cutting linkage 300 performs a cutting operation, the feed pressing block driving member 126 drives the feed pressing block 125 to move downward, thereby pressing and securing the tab coil within the feed guide groove 121a. This prevents the tab coil from shifting during the cutting process, thereby improving the overall cutting accuracy. In this embodiment, the feed pressing block driving member 126 is a cylinder structure, thereby enabling the feed pressing block 125 to be raised and lowered.

[0029] Please refer again Figure 2In one embodiment, the feeding module 120 further includes a feeding guide wheel 127 and a feeding guide lifting member 128. The feeding guide wheel 127 is arranged above the feeding guide groove 121a. The feeding guide lifting member 128 is connected to the feeding guide wheel 127. The feeding guide lifting member 128 is used to drive the feeding guide wheel 127 to perform reciprocating displacement in the direction of the feeding guide groove 121a.

[0030] It should be noted that when the tab coil is being fed and moved within the feed guide groove 121a, the feed guide lifting member 128 drives the feed guide wheel 127 to press downward in the direction of the feed guide groove 121a, so that the feed guide wheel 127 abuts against the tab coil within the feed guide groove 121a. Thus, the guide movement of the feed guide wheel 127 allows the tab coil to be better fed and moved within the feed guide groove 121a. In this embodiment, the feed guide lifting member 128 is a cylinder structure, which can realize the lifting and lowering drive operation of the feed guide wheel 127.

[0031] See also Figure 4 In one embodiment, the separation module 210 includes a separation guide rail 211, a separation sliding plate 212, an elastic return member 213, and a follower cam 214. The separation guide rail 211 is disposed at the discharge end of the feed guide groove 121a. The separation sliding plate 212 is slidably disposed on the separation guide rail 211. The adsorption member 220 is disposed on the separation sliding plate 212. The elastic return member 213 is respectively connected to the separation sliding plate 212 and the feed platform 121. The follower cam 214 is disposed on one side of the separation sliding plate 212 and is connected to the linkage module 210. In this embodiment, the elastic return member 213 is a return spring.

[0032] It should be noted that the separation sliding plate 212 is slidably arranged on the separation guide rail 211, so that it can move toward or away from the feed table 121 on the separation guide rail 211, thereby driving the adsorption member 220 to adsorb and move the tab coil at the discharge end of the feed guide groove 121a. By providing a follower cam 214 on one side of the separation sliding plate 212, it can cooperate with the linkage module 210 for linkage operation, thereby realizing the sliding control of the separation sliding plate 212. At the same time, the elastic reset member 213 is respectively connected to the separation sliding plate 212 and the feed table 121. In this way, the elastic action of the elastic reset member 213 can drive the separation sliding plate 212 to reset and slide, thereby making the overall structure more compact and improving the consistency of the overall production and processing operation.

[0033] In one embodiment, please refer to Figure 4The adsorption member 220 includes an adsorption block 221, which is arranged on the separation sliding plate 212. A plurality of adsorption holes 221a are provided on the adsorption block 221. In this way, the tab coil can be adsorbed and fixed through the adsorption holes 221a on the adsorption block 221.

[0034] See also Figure 5 In one embodiment, the linkage module 320 includes a lifting drive 321, a lifting bracket 322, and a linkage guide plate 323. The lifting drive 321 is connected to the lifting bracket 322. The linkage guide plate 323 is disposed on one side of the lifting bracket 322. The cutter 310 is disposed on the lifting bracket 322. The linkage guide plate 323 has a linkage guide slope 323a formed on it. The follower cam 214 abuts against the linkage guide slope 323a. In this embodiment, the lifting drive is a pneumatic cylinder.

[0035] It should be noted that when the cutter 310 needs to perform a tab cutting operation, the lifting drive 321 drives the lifting bracket 322 to move downward, thereby driving the cutter 310 to perform a downward cutting operation, thereby enabling the tab cutting operation to be performed on the tab at the discharge end of the feed guide groove 121a. In this embodiment, when the lifting drive 321 drives the lifting bracket 322 to move downward, the linkage guide plate 323 moves downward synchronously. At this time, the adsorption member 220 stops the adsorption operation, the follower cam 214 moves along the linkage guide inclined surface 323a, and the separation sliding plate 212 moves toward the discharge end of the feed guide groove 121a under the elastic force of the elastic return member 213, thereby enabling the adsorption member 220 to adsorb and fix the end of the next tab coil. When the cutting operation is completed, the lifting drive 321 drives the lifting bracket 322 to perform a lifting movement. At this time, the linkage guide plate 323 performs an upward movement, thereby driving the follower cam 214 to move along the linkage guide inclined surface 323a, and then the separation sliding plate 212 moves in the direction away from the discharge end of the feeding guide groove 121a, thereby moving the end of the next tab coil to the set position, and realizing the linkage drive operation of the linkage module 320.

[0036] Please refer again Figure 5 In one embodiment, the cutting linkage device 300 also includes a punching head 330, which is arranged on a side surface of the lifting bracket 322 away from the cutter 310. In this way, the punching head 330 can punch the tab while the cutter 310 is performing cutting processing, thereby improving the continuity of production and processing and improving the overall production and processing efficiency.
