Referring to fig. 1 to 4, the present application provides a battery tab processing apparatus 10, which includes a guide roller 11, a laser 12, a dust extraction box 13, and a rim charge collection assembly 14. The guide roller 11 includes a feed roller 111 and a discharge roller 112, and the tab 30 extends in a vertical direction and bypasses the discharge roller 112 after bypassing the feed roller 111. The laser light emitted from the laser 12 corresponds to a processing position between the feed roller 111 and the discharge roller 112. The dust box 13 is used for dust extraction and corresponds to a processing position. The rim charge collecting assembly 14 includes a vacuum suction belt 141 and a rim charge collecting cylinder 142, the vacuum suction belt 141 is ring-shaped and has an effective working surface 141a abutting against the tab, the effective working surface 141a extends in the vertical direction with one end located below the processing position and the other end extending to the rim charge collecting cylinder 142. The effective working surface 141a can vacuum-adsorb the tab and move in the vertical direction in synchronization with the tab.

It will be appreciated that the feed roll 111 and the discharge roll 112 cooperate to support and conduct the tabs. For a part of the tab between the feed roller 111 and the discharge roller 112, it is required to gradually move from the feed roller 111 to the discharge roller 112 in the vertical direction.

It will be appreciated that the laser light from the laser 12 may be directed onto a portion of the tab between the feed roll 111 and the discharge roll 112 to process the portion of the tab. Or the laser light emitted from the laser 12 may be finally irradiated onto a part of the tab between the feed roller 111 and the discharge roller 112 after the optical path is changed, so that the part of the tab is processed. It can be understood that when the laser irradiates on a part of the tab between the feeding roller 111 and the discharging roller 112, the laser swings and moves within a certain range under the action of the internal vibrating mirror, so that the laser processing on the part of the tab is smoothly completed by matching with the movement of the part of the tab along the vertical direction, and thus, the moving range of the laser between the feeding roller 111 and the discharging roller 112 is the processing position.

It can be understood that, since a part of the tab between the feeding roller 111 and the discharging roller 112 moves along the vertical direction, the tab after being processed by the laser will carry the cut edge material to move along the vertical direction synchronously, and further be smoothly received and vacuum absorbed by the effective working surface 141a of the vacuum absorbing belt 141 below the processing position, so that the effective working surface 141a drives the tab and the edge material to move synchronously along the vertical direction, and after a certain distance of movement, the tab will separate from the effective working surface 141a to come to the discharging roller 112, and the edge material will move along with the effective working surface 141a to the edge material collecting cylinder 142, and finally be uniformly collected by the edge material collecting cylinder 142, so as to avoid the edge material from falling randomly.

It can be understood that the dust box 13 corresponds to the "processing position", so that dust generated when the laser processes a part of the tab located between the feeding roller 111 and the discharging roller 112 can be timely sucked away by the dust box 13, and potential safety hazards caused by dust pollution of the tab can be avoided.

It will be appreciated that lasers 12 of different powers may be employed for different shaped tabs, the more complex the shape of the tab, the smaller the spacing, the higher the power of the laser.

In the battery tab processing apparatus 10, the tab is processed by the laser in the process of moving between the feeding roller 111 and the discharging roller 112 along the vertical direction, and dust is pumped by the dust pumping box 13 to avoid dust pollution on the tab, and the tab and cut rim charge after laser processing are adsorbed on the effective working surface 141a of the vacuum adsorption belt 141 by vacuum, so that the vacuum adsorption belt 141, the tab and the rim charge synchronously move, and finally the tab leaves the vacuum adsorption belt 141 and is led out by the discharging roller 112, and the rim charge is uniformly collected by the rim charge collecting cylinder 142 along with the movement of the vacuum adsorption belt 141, thereby avoiding the rim charge from falling randomly. In addition, when the effective working surface 141a adsorbs the tab and the rim charge, the stability of the tab is maintained and the vibration of the tab is reduced, so that the processing of the tab by laser precision can be facilitated.

As shown in fig. 1 and 2, specifically, the dust box 13 includes a mesh plate 131, a dust extraction cover 132, and a dust extraction tube 133, where the mesh plate 131 has meshes and corresponds to a processing position, the dust extraction cover 132 is connected to a periphery of the mesh plate 131, the dust extraction tube 133 is connected to one end of the dust extraction cover 132 far away from the mesh plate 131, the dust extraction cover 132 gradually contracts from the mesh plate 131 to the dust extraction tube 133 to be cone-shaped, and dust at the processing position enters the dust extraction tube 133 along the dust extraction cover 132 after passing through the meshes on the mesh plate 131 and is collected at one end of the dust extraction tube 133 far away from the dust extraction cover 132.

Referring to fig. 1 to 3, in particular, in the present application, the rim charge collecting assembly 14 includes a vacuum pumping device (not shown), the vacuum adsorption belt 141 is provided with a plurality of air holes 141b, the discharging roller 112 is vertically higher than the rim charge collecting cylinder 142, and the vacuum pumping device is disposed at a side of the effective working surface 141a away from the discharging roller 112 and corresponds to the plurality of air holes 141b of the effective working surface 141 a. It will be appreciated that the vacuum device will vacuum the tab to the active working surface 141a via the air holes 141b. Since the position of the discharging roller 112 is higher than the rim charge collecting cylinder 142, in the vertical direction, a part of the effective working surface 141a is located between the processing position and the discharging roller 112, and the other part of the effective working surface 141a is located between the discharging roller 112 and the rim charge collecting cylinder 142, so that after the tab and the rim charge move synchronously with the effective working surface 141a to the discharging roller 112, the tab leaves the effective working surface 141a and is led out through the discharging roller 112, and the rim charge is continuously absorbed by the effective working surface 141a and moves towards the rim charge collecting cylinder 142, thereby realizing mutual separation of the tab and the rim charge.

Specifically, in the present application, the rim charge collecting assembly 14 includes a servo motor (not shown) and two transfer wheels (not shown) disposed at intervals in a vertical direction, the vacuum suction belt 141 bypasses the two transfer wheels, and the servo motor is connected to any one of the two transfer wheels to drive the vacuum suction belt to move through the two transfer wheels. The servo motor serves as a power means to power the movement of the two transfer wheels and the vacuum suction belt 141. It should be noted that, the speed of the servo motor driving the transfer wheel to rotate should ensure that the moving speed of the vacuum suction belt 141 matches the speed of the tab moving in the vertical direction.

Specifically, in the present application, the rim charge collector 142 is a vacuum pipe having a wind speed exceeding 23 m/s. By providing the rim charge collecting cylinder 142 with a large suction force, it is possible to ensure that the rim charge is smoothly carried away from the vacuum suction belt 141. It should be noted that, with the vacuum suction belt 141, there is no vacuum suction effect of the vacuum suction device at the position corresponding to the transfer wheel located at the lower position, so that the suction of the rim charge cannot be continued, and thus, when the rim charge moves to the position closest to the rim charge collection cylinder 142 along with the effective working surface 141a, the rim charge will be smoothly separated from the effective working surface 141a and enter the rim charge collection cylinder 142.

Further, a wind speed sensor (not shown) for detecting a wind speed is installed in the rim charge collecting cylinder 142. The wind speed in the rim charge collecting cylinder 142 can be detected in real time by the wind speed sensor so as to ensure that the rim charge is collected smoothly.

It will be appreciated that the anti-shake wheel 16 is disposed corresponding to the straight plate 152 to form a gap with the straight plate 152 for passing the tab, the straight plate 152 cooperates with the anti-shake wheel 16 to limit movement of the tab in the vertical direction, and the inclined plate 151 is disposed to guide the tab bypassing the feed roller 111 into the gap between the straight plate 152 and the anti-shake wheel 16.

Specifically, the anti-shake wheel 16 is disposed parallel to the feed roller 111, and a portion of the tab extending in the vertical direction is tangential to both the feed roller 111 and the anti-shake wheel 16. It can be appreciated that by setting the relative positions of the anti-shake wheel 16 and the feeding roller 111, the feeding roller 111 and the anti-shake wheel 16 can be respectively abutted against two opposite sides of the tab, so as to cooperate with each other to maintain the tab moving along the vertical direction and avoid the tab from swinging and shaking.

It can be appreciated that the width of the gap is changed by making the smoothing plate 15 and the anti-shake wheel 16 close to or far away from each other so as to adjust the relative positions of the smoothing plate and the anti-shake wheel, thereby facilitating the tab to extend into the gap between the smoothing plate and the anti-shake wheel or making the gap fit for tabs with different thicknesses to pass through. Specifically, the battery tab processing apparatus 10 includes a first bracket 18 and a second bracket 19, the first bracket 18 is slidably connected to the base 17, and the second bracket 19 is fixedly mounted to the base 17. The pacifier plate 15 is fixedly arranged on the first bracket 18, and the driving cylinder 21 is arranged on the base 17 and can drive the first bracket 18 to drive the pacifier plate 15 to slide relative to the base 17.
