Description

Technical Field

[0001] The invention relates to the technical field of roll welding machines, in particular to an ultrasonic roll welding machine for producing composite current collectors. Background Art

[0002] At present, the ultrasonic roll welding machine converts electrical energy into high-frequency mechanical vibration energy through an ultrasonic generator, and then transmits the mechanical vibration energy to the welding roller through a transducer. When the welding roller contacts the material to be welded, the high-frequency vibration generates friction heat on the surface of the material, thereby partially melting the material and achieving welding under pressure. The composite current collector roll welding machine usually adopts ultrasonic welding technology. When the ultrasonic vibration is transmitted to the composite current collector through the welding mold, friction heat is generated between two or more layers of the composite current collector under pressure, causing the material to partially melt and achieve firm welding. In the existing ultrasonic rolling welding machine, it is necessary to weld the metal foil for a long time. When the metal foil shifts during the transmission process, resulting in an error in the welding position, the metal foil is not restricted and continues to be transmitted and welded, resulting in a large number of errors in the welding position of the metal foil after the welding is completed, increasing the loss of the metal foil. Summary of the invention

When the metal foil tends to deviate or tilt, the rubber ring and the outer cover wheel transmit the tendency to the top ring and the top block, so that the top block tends to expand outward, thereby limiting the movement and tilt tendency of the metal foil. When the metal foil begins to tilt, the expanded top block drives the rubber ring to change, clamping the metal foil between the connecting shafts, making it unable to continue to transmit, thereby preventing the equipment from continuing to weld after an error in the welding position occurs, resulting in a large number of errors in the welding position of the metal foil after the welding is completed, thereby increasing the loss of the metal foil. Blocks are rotatably installed at both ends of the outer side of the connecting shaft, and spring plates are fixedly installed between the blocks. The spring plates are symmetrically installed along the center position of the axis of the blocks.

The rotating shaft cannot continue to drive the rotating cylinder to rotate. At the same time, the pressure rod presses the metal foil passing through below under its own gravity, ensures the tightness of the winding, and cooperates with the top shaft and the bottom shaft to prevent the metal foil from bending.

[0007] The present invention provides an ultrasonic rolling welding machine for producing a composite current collector. It has the following beneficial effects: 1. The ultrasonic rolling welding machine for the composite current collector production, through the sliding adaptation of the top block and the top ring, when the metal foil tends to deviate or tilt, transmits the trend to the top ring and the top block through the rubber ring and the outer cover wheel, so that the top block tends to expand outward, restricting the movement and tilting trend of the metal foil. When the metal foil begins to tilt, the expanded top block drives the rubber ring to change, clamping the metal foil between the connecting shafts, making it unable to continue to transmit, preventing the equipment from continuing to weld after an error in the welding position, resulting in a large number of errors in the welding position of the metal foil after the welding is completed, increasing the loss of the metal foil.

The ultrasonic roll welding machine for producing the composite current collector, through the cooperation between the top plate and the elastic ring, utilizes the elastic deformation of the elastic ring during the welding and tightening process to buffer the contact pressure between the metal foil and the roll welding head, thereby avoiding excessive pressure that causes the roll welding head to directly penetrate the metal foil during the welding process, resulting in the metal foil being broken.

At the same time, the winding mechanism makes it easier to wind up the welded material.

[0010] 4. The ultrasonic roll welding machine for the composite current collector production cooperates with the groove plate and the rubber wheel to restrict the metal foil on the side of the metal foil close to the welding position, so that the side of the metal foil close to the welding position passes through the groove of the groove plate and cooperates with the rubber wheel to press the metal foil to prevent the metal foil from being unable to be separated from the roll welding head after welding and rotating with the roll welding head, causing damage to the metal foil.

[0011] 5. The ultrasonic rolling welding machine for the composite current collector production uses the elastic deformation of the elastic plate. After an error occurs in the welding position, the material guide mechanism limits the movement of the metal foil, and the clamping connection between the protrusion and the protruding ring can be continuously changed. The rotating shaft cannot continue to drive the rotating drum to rotate. At the same time, the pressure rod presses the metal foil passing through below under its own gravity, ensuring the tightness of the winding while cooperating with the top shaft and the bottom shaft to prevent the metal foil from bending.

At the same time, the two layers of metal foil are pressed and tightly fitted by the rubber wheel 207. A top plate 208 is fixedly installed on the top of the elastic ring 209, and the top plate 208 is located directly below the rolling welding head 5.

[0017] The bottom shaft 210 is evenly installed along the inclined groove of the slot seat 205. A side plate 214 is fixedly installed on one side of the slot seat 205. A slide bar 213 is slidably installed on the inner wall of the side plate 214. A connecting plate 212 is fixedly installed on the top of the slide bar 213. A top shaft 211 is fixedly installed on the outer side of the connecting plate 212. The top shaft 211 corresponds to the bottom shaft 210 one by one. A spring 215 is fixedly installed between the connecting plate 212 and the side plate 214. The spring 215 is located on the outer side of the slide bar 213. A slot plate 206 is fixedly installed on the side of the slot seat 205 away from the side plate 214. The slot plate 206 is fixedly installed on the side of the slot seat 205 away from the side plate 214. 6 is provided with a groove. During the welding process, the slide 204 is driven upward by the cylinder 203 to make the compressed metal foil contact the roll welding head 5, and the compressed metal foil is welded together by the roll welding head 5. When the metal foil is driven upward to tightly contact the roll welding head 5, the top plate 208 is used to support the bottom of the metal foil.

[0018] The third embodiment is based on the first and second embodiments. Figures 8 to 9As shown, the winding mechanism 4 includes a rotating shaft 41, one end of which is connected to the output end of the second motor 8, and a rotating arm 42 is rotatably installed on the side of the outer side of the rotating shaft 41 close to the second motor 8, and a pressure rod 45 is fixedly installed on the end of the rotating arm 42 away from the rotating shaft 41, and a convex ring 43 is fixedly installed on the outer side of the rotating shaft 41, and grooves are evenly arranged on the outer side of the convex ring 43. A rotating drum 44 is rotatably installed at the center position of the outer side of the rotating shaft 41, and the welded metal foil passes through the bottom of the pressure rod 45, and the wound roller is inserted into the outer side of the rotating drum 44, and the rotating drum 44 is supported and fixed on the inner side of the roller by the rubber strip 46 on the outer side of the rotating drum 44, and the rotating shaft 41 is driven to rotate by the second motor 8, and the convex ring 43 is driven to rotate by the rotation of the rotating shaft 41, and the clamping connection between the convex ring 43 and the convex block 48 is used to drive the connecting drum 47 to rotate together with the rotating drum 44, so that the roller drives the welding The finished materials are rolled up and collected, and rubber strips 46 are evenly installed on the outside of the rotating drum 44. Connecting drums 47 are fixedly installed at both ends of the rotating drum 44. Empty grooves are symmetrically opened on the outside of the connecting drum 47. Bumps 48 are slidably installed at the empty grooves of the connecting drum 47. The end of the bump 48 close to the convex ring 43 is clamped with the groove of the convex ring 43. An elastic plate 49 is fixedly installed on the outside of the connecting drum 47. During the rolling process, when the positions of the two layers of metal foil are offset, resulting in an error in the welding position, the material guiding mechanism 3 limits the movement of the metal foil and limits the rotation of the rotating drum 44 through the metal foil and the roller. At this time, the bump 48 transmits the limiting force to the elastic plate 49, causing the elastic plate 49 to deform, and continuously changes the clamping position between the bump 48 and the convex ring 43, so that the rotating drum stops rotating, and the center position of the inner wall of the elastic plate 49 is fixedly connected to the end of the bump 48 away from the convex ring 43.

[0019] When in use, a worker fixes the two metal foil rolls to be welded through a material rack 7, so that the metal foil first passes through the material guiding mechanism 3, and the metal foil is driven and guided by the material guiding mechanism 3, and the driven metal foil is restricted. After the metal foil passes through the material guiding mechanism 3, it enters the material pressing mechanism 2, and the upper and lower layers of metal foil are pressed together by the material pressing mechanism 2. The two layers of metal foil are overlapped with the material guiding mechanism 3, and pressure is applied upward to the bottom of the overlapping metal foil. The first motor 6 is used to drive the rolling welding head 5 to rotate, and the rolling welding head 5 welds the two layers of metal foil through ultrasonic vibration. After welding, the metal foil passes through the pressing mechanism 2, and the winding mechanism 4 is driven by the second motor 8 to run, so that the welded metal foil is wound up.

[0020] In the process of guiding the metal foil by the material guide mechanism 3, the metal foil passes through the two connecting shafts 33, contacts the upper and lower metal foils through the rubber ring 36 outside the outer cover wheel 32, and drives the sleeve block 34 through the spring plate 35, and drives the two connecting shafts 33 to approach each other through the sleeve block 34. In the process of metal foil transmission, the metal foil driven by the winding mechanism 4 drives the rubber ring 36 and the outer cover wheel 32 to rotate along the axial position of the connecting shaft 33. When the metal foil deviates and tilts during the transmission process, the metal foil with a tendency to deviate transmits the tendency to deviate to the outer cover wheel 32 through the friction force between the metal foil and the rubber ring 36, so that the outer cover wheel 32 transmits the tendency to the top ring 38, so that the top ring 38 has a tendency to move. By using the conical surface of the top ring 38 and the arc surface of the opposite surface of the top block 37, after the top ring 38 has a tendency to move, the top block 37 has a tendency to press the rubber ring 36 outward.

[0021] After the metal foil passes through the material guiding mechanism 3, the two layers of metal foil are clamped by the top shaft 211 and the bottom shaft 210. When the spring 215 drives the connecting plate 212 to move downward, the top shaft 211 drives the connecting plate 212 to press the metal foil downward, so that the two layers of metal foil are tightly pressed together and the metal foil on one side is welded at the same time. The metal foil passes through the inside of the groove plate 206, and the two layers of metal foil are pressed and tightly fitted by the rubber wheel 207. During the welding process, the slide seat 204 is driven upward by the cylinder 203 to make the pressed metal foil contact the roll welding head 5, and the pressed metal foil is welded together by the roll welding head 5. When the metal foil is driven upward to contact the roll welding head 5 tightly, the top plate 208 is used to support the bottom of the metal foil. At the same time, during the contact process, the elastic deformation of the elastic ring 209 provides a certain buffer range during the contact welding process.

[0022] After the metal foil is welded, the welded metal foil passes through the bottom of the pressure rod 45, and the wound roller is inserted into the outside of the rotating drum 44, and is supported and fixed on the inner side of the roller by the rubber strip 46 on the outside of the rotating drum 44. The rotating shaft 41 is driven to rotate by the second motor 8, and the convex ring 43 is driven to rotate by the rotation of the rotating shaft 41. The engagement between the convex ring 43 and the protrusion 48 is used to drive the connecting cylinder 47 and the rotating drum 44 to rotate together, so that the roller drives the welded material to be rolled up and collected. At the same time, during the rolling process, when the positions of the two layers of metal foil are offset, resulting in an error in the welding position, the material guiding mechanism 3 limits the movement of the metal foil and limits the rotation of the rotating drum 44 through the metal foil and the roller. At this time, the protrusion 48 transmits the limiting force to the elastic plate 49, causing the elastic plate 49 to deform, and continuously changes the engagement position between the protrusion 48 and the convex ring 43, so that the rotating drum stops rotating.
