The laser assembly may be configured to emit laser to the abutting surface. During laser cutting, the electrode plate may abut against the abutting surface and closely fits the abutting surface to extend fully and thus may be in a flattened state, and therefore, the problem of defocusing caused by a wavy edge may be solved. Moreover, supported by the abutting surface, the electrode plate may be tensioned and not prone to shaking, and therefore, problems such as failing to cut off the incoming material due to easy shaking of the electrode plate may be effectively solved. ## Claims ### Claim 1 An electrode plate supporting device for use in coordination with a laser assembly, the electrode plate supporting device comprising: a body constructed with an abutting surface for abutting against an electrode plate to tension the electrode plate, wherein the laser assembly is configured to emit laser to the abutting surface. ### Claim 2 (depends on 1) The electrode plate supporting device according to claim 1, wherein the body comprises a light absorbing component capable of absorbing the laser passing through the electrode plate: or, the body comprises a light transmitting component capable of allowing the laser passing through the electrode plate to transmit therethrough. ### Claim 3 (depends on 1) The electrode plate supporting device according to claim 1, wherein the body comprises a light absorbing component for absorbing the laser and a light transmitting component for allowing the laser to transmit therethrough, and the light transmitting component covers and is connected to the light absorbing component: wherein a surface, far away from the light absorbing component, of the light transmitting component is constructed with an abutting surface. ### Claim 4 (depends on 3) The electrode plate supporting device according to claim 3, wherein the light absorbing component is cylindrical, and the light transmitting component covers an outer peripheral wall of the light absorbing component. ### Claim 5 (depends on 3) The electrode plate supporting device according to claim 3, wherein a hole is formed within the light absorbing component and extends through the light absorbing component along an axis of the light absorbing component. ### Claim 6 (depends on 5) The electrode plate supporting device according to claim 5, further comprising an air extraction unit having an air extraction opening communicated with one end of the hole, or further comprising an air blowing unit having an air blowing opening communicated with one end of the hole. ### Claim 7 (depends on 5) The electrode plate supporting device according to claim 5, further comprising an air blowing unit and an air extraction unit, wherein one of two opposite ends of the hole is communicated with an air extraction opening of the air extraction unit, and the other one is communicated with an air blowing opening of the air blowing unit. ### Claim 8 (depends on 5) The electrode plate supporting device according to claim 5, further comprising a supporting component disposed to pass through the hole, wherein the supporting component and a wall of the hole form a flowing space for air to flow;
