An ultrasonic seam welder for the production of composite current collectors

Abstract

The present invention discloses an ultrasonic roll welding machine for the production of composite current collectors. The present invention relates to the technical field of ultrasonic welding machines. When the metal foil deviates during the transmission process, resulting in an incorrect welding position, the metal foil is not restricted and still continues to be transmitted and welded, resulting in a large number of errors at the welding position of the metal foil after welding is completed, increasing the loss of the metal foil. Therefore, through the sliding fit of the top block and the top ring, when the metal foil shows a tendency to deviate or tilt, the tendency is transmitted to the top ring and the top block through the rubber ring and the outer cover wheel, causing the top block to show a tendency to expand outwards, restricting the movement and tilting tendency of the metal foil. After the metal foil starts to tilt, the expanded top block drives the rubber ring to deform, clamping the metal foil between the connecting shafts, making it unable to continue to be transmitted, preventing continuous welding after an incorrect welding position occurs, resulting in a large number of errors at the welding position of the metal foil after welding is completed, and increasing the loss of the metal foil.

Description

Technical Field

[0001] The present invention relates to the technical field of roll welding machines, and particularly to an ultrasonic roll welding machine for the production of composite current collectors. Background Art

[0002] At present, an ultrasonic roll welding machine converts electrical energy into high-frequency mechanical vibration energy through an ultrasonic generator, and then transfers 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 frictional heat on the material surface, thereby locally 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 conducted to the composite current collector through the welding die, under the action of pressure, frictional heat is generated between two or more layers of composite current collectors, locally melting the material and achieving firm welding;

[0003] In the existing ultrasonic roll welding machines, it is necessary to weld the metal foil for a long time. When the metal foil deviates during the transmission process, resulting in an incorrect welding position, the metal foil is not restricted and still continues to be transmitted for welding, resulting in a large number of errors at the welding position of the metal foil after welding is completed, increasing the loss of the metal foil. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An ultrasonic roll welding machine for the production of composite current collectors, comprising:

[0005] A frame body, which has a framework for supporting the mechanism components, and one side of the top of the frame body is fixedly installed with a material rack;

[0006] A material pressing mechanism, which is used to press the metal foil during the welding process, and the material pressing mechanism is fixedly installed at the center position of the top of the frame body;

[0007] A roll welding head, which is rotatably installed inside the material pressing mechanism, and a first motor is fixedly installed on the outside of the material pressing mechanism, and the output end of the first motor is connected to the roll welding head.

[0008] A material guiding mechanism, which is used to limit the position of the metal foil during its movement, and the material guiding mechanism is installed between the material rack and the material pressing mechanism;

[0009] A winding mechanism, which is used to wind the welded material, and a second motor is fixedly installed on the outside of the frame body, and the output end of the second motor is connected to the winding mechanism;

[0010] Among them, the material guiding mechanism includes a fixing plate, which is installed between the material rack and the material pressing mechanism. An inclined groove is formed on the outer side of the fixing plate, and a connecting shaft is slidably installed at the inclined groove of the fixing plate. A fixed ring is fixedly installed on the outer side of the connecting shaft, and the fixed rings are symmetrically installed along the central position of the connecting shaft. An outer cover wheel is slidably installed on the outer side of the connecting shaft. The outer cover wheel is located outside the fixed ring. A top ring is fixedly installed on the inner wall of the outer cover wheel, and the outer side of the top ring is a conical surface. A rubber ring is fixedly installed on the outer side of the outer cover wheel. A top block is slidably installed on the inner wall of the outer cover wheel, and the opposite surfaces of the top block are arc-shaped surfaces, and the opposite surfaces of the top block are slidably adapted to the outer side of the top ring. Through the sliding adaptation of the top block and the top ring, when the metal foil shows a tendency of deviation or inclination, the tendency is transmitted to the top ring and the top block through the rubber ring and the outer cover wheel, causing the top block to have a tendency to expand outwards, restricting the movement and inclination tendency of the metal foil. When the metal foil starts to incline, the expanded top block drives the rubber ring to deform, clamping the metal foil between the connecting shafts, making it unable to continue to drive, preventing the equipment from continuing to perform welding work after a welding position error occurs, resulting in a large number of errors at the welding position of the metal foil after welding is completed, increasing the loss of the metal foil. Sleeve blocks are rotatably installed at both ends of the outer side of the connecting shaft, and a spring plate is fixedly installed between the sleeve blocks. The spring plates are symmetrically installed along the central position of the axis of the sleeve blocks.

[0011] Preferably, the material pressing mechanism includes a groove rack, the top of the outer side of the groove rack is fixedly connected to a first motor, a sliding seat is slidably installed on the inner wall of the groove rack, a cylinder is fixedly installed at the bottom of the sliding seat, and the cylinders are symmetrically installed along the central position of the axis of the sliding seat. Positioning columns are fixedly installed on the inner wall of the groove rack, and the positioning columns are symmetrically installed along the central position of the axis of the groove rack. The inner wall of the sliding seat is slidably connected to the outer side of the positioning column. A groove seat is fixedly installed at the top of the sliding seat, a strip groove is formed at the top of the groove seat, and an elastic ring is fixedly installed at the strip groove of the groove seat. A top plate is fixedly installed at the top of the elastic ring. Through the cooperation between the top plate and the elastic ring, during the process of welding and pressing tightly, by using the elastic deformation of the elastic ring, the contact pressure between the metal foil and the roller welding head is buffered, avoiding excessive pressure, which may cause the roller welding head to directly penetrate the metal foil during the welding process, resulting in the fragmentation of the metal foil. The top plate is located directly below the roller welding head, and an inclined groove is formed at the top of the groove seat, and a bottom shaft is rotatably installed at the inclined groove of the groove seat.

[0012] Preferably, the bottom shaft is uniformly installed along the slope of the inclined groove of the groove seat. One side of the groove seat is fixedly installed with a side plate. A sliding rod is slidably installed on the inner wall of the side plate. The top of the sliding rod is fixedly installed with a connecting plate. The outside of the connecting plate is fixedly installed with a top shaft. The top shaft corresponds to the bottom shaft one by one. A spring is fixedly installed between the connecting plate and the side plate. The spring drives the connecting plate to move downward, so that the top shaft and the bottom shaft are closely attached to each other. During the welding movement of the material, the two metal foils can be closely overlapped, avoiding folding, ensuring the welding quality, and cooperating with the winding mechanism to make the welded material easier to wind. The spring is located outside the sliding rod. One side of the groove seat away from the side plate is fixedly installed with a groove plate. A strip groove is opened on the outside of the groove plate. The groove plate cooperates with the rubber wheel to restrict the metal foil on one side of the metal foil close to the welding position, so that one side of the metal foil close to the welding position passes through the strip groove of the groove plate and cooperates with the rubber wheel to press the metal foil, preventing the metal foil from being unable to separate from the roll welding head after welding and rotating with the roll welding head, resulting in damage to the metal foil. And the top of the groove plate is uniformly provided with wheel grooves, and rubber wheels are rotatably installed at the wheel grooves of the groove plate.

[0013] Preferably, the winding mechanism includes a rotating shaft. One end of the rotating shaft is connected to the output end of the second motor. A rotating arm is rotatably installed on the outside of the rotating shaft close to the second motor. A pressing rod is fixedly installed at the end of the rotating arm away from the rotating shaft. A convex ring is fixedly installed on the outside of the rotating shaft. Grooves are uniformly arranged on the outside of the convex ring. A rotating cylinder is rotatably installed at the central position on the outside of the rotating shaft. Rubber strips are uniformly installed on the outside of the rotating cylinder. Connecting cylinders are fixedly installed at both ends of the rotating cylinder. Empty grooves are symmetrically opened on the outside of the connecting cylinder. Convex blocks are slidably installed at the empty grooves of the connecting cylinder. One end of the convex block close to the convex ring is clamped with the groove of the convex ring. An elastic plate is fixedly installed on the outside of the connecting cylinder. Through the elastic deformation of the elastic plate, after an error occurs at the welding position, the guiding mechanism restricts the movement of the metal foil, and the clamping between the convex block and the convex ring can be continuously changed, and the rotating shaft cannot continue to drive the rotating cylinder to rotate. At the same time, under its own gravity, the pressing rod presses the metal foil passing through below, ensuring the winding tightness and cooperating with the top shaft and the bottom shaft to prevent the metal foil from being bent. The central position of the inner wall of the elastic plate is fixedly connected to the end of the convex block away from the convex ring.

[0014] The present invention provides an ultrasonic roll welding machine for the production of composite current collectors. It has the following beneficial effects:

[0015] 1. The ultrasonic roll welding machine for producing the composite current collector restricts the movement and tilting tendency of the metal foil by the sliding fit between the top block and the top ring. When the metal foil shows a tendency to shift or tilt, the tendency is transmitted to the top ring and the top block through the rubber ring and the outer cover wheel, causing the top block to expand outward, thereby restricting the movement and tilting tendency of the metal foil. After the metal foil starts to tilt, the expanded top block drives the rubber ring to deform, clamping the metal foil between the connecting shafts so that it cannot continue to move, preventing the equipment from continuing the welding operation after a welding position error occurs, resulting in a large number of errors at the welding position of the metal foil after welding and increasing the loss of the metal foil.

[0016] 2. The ultrasonic roll welding machine for producing the composite current collector buffers the contact pressure between the metal foil and the roll welding head by the cooperation between the top plate and the elastic ring during the welding tightening process, using the elastic deformation of the elastic ring to avoid excessive pressure, which may cause the roll welding head to directly penetrate the metal foil during the welding process, resulting in the fragmentation of the metal foil.

[0017] 3. The ultrasonic roll welding machine for producing the composite current collector drives the connecting plate to move downward through the spring, making the top shaft and the bottom shaft fit tightly together. During the welding movement of the material, the two layers of metal foil can be closely overlapped to avoid folding, ensuring the welding quality. At the same time, in cooperation with the winding mechanism, the welded material is easier to wind.

[0018] 4. The ultrasonic roll welding machine for producing the composite current collector restricts the metal foil on one side close to the welding position by the cooperation between the groove plate and the rubber wheel. The metal foil on one side close to the welding position passes through the strip grooves of the groove plate and cooperates with the rubber wheel to press the metal foil, preventing the metal foil from being unable to separate from the roll welding head after welding and rotating with the roll welding head, resulting in damage to the metal foil.

[0019] 5. The ultrasonic roll welding machine for producing the composite current collector, through the elastic deformation of the elastic plate, after a welding position error occurs, the material guiding mechanism restricts the movement of the metal foil. The clamping between the convex block and the convex ring can be continuously changed, and the rotating shaft cannot continue to drive the rotating cylinder to rotate. At the same time, under its own gravity, the pressure rod presses the metal foil passing through below, ensuring the winding tightness and cooperating with the top shaft and the bottom shaft to prevent the metal foil from being bent.

Specific embodiments

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0031] The first embodiment is as Figures 1 to 2 shown in Figures 6 to 7 and provides a technical solution of the present invention: An ultrasonic seam welder for the production of composite current collectors, comprising:

[0032] A frame body 1, which has a framework for supporting the mechanism components, and a material rack 7 is fixedly installed on one side of the top of the frame body 1;

[0033] A blanking mechanism 2, which is used to press the metal foil during the welding process, and the blanking mechanism 2 is fixedly installed at the center position on the top of the frame body 1;

[0034] A seam welding head 5, which is rotatably installed inside the blanking mechanism 2. A first motor 6 is fixedly installed outside the blanking mechanism 2, and the output end of the first motor 6 is connected to the seam welding head 5.

[0035] A material guiding mechanism 3, which is used to limit the position of the metal foil during its movement, and the material guiding mechanism 3 is installed between the material rack 7 and the blanking mechanism 2;

[0036] A winding mechanism 4, which is used to wind the welded material. A second motor 8 is fixedly installed outside the frame body 1, and the output end of the second motor 8 is connected to the winding mechanism 4;

[0037] Among them, the material guiding mechanism 3 includes a fixing plate 31, which is installed between the material rack 7 and the blanking mechanism 2. An inclined groove is formed on the outside of the fixing plate 31, and a connecting shaft 33 is slidably installed at the inclined groove of the fixing plate 31. A fixing ring 39 is fixedly installed on the outside of the connecting shaft 33. The metal foil passes through between the two connecting shafts 33, and contacts the upper and lower layers of metal foils through the rubber ring 36 on the outside of the outer cover wheel 32. At the same time, the elastic plate 35 drives the sleeve block 34, and the two connecting shafts 33 are driven to approach each other through the sleeve block 34. During the transmission of the metal foil, the metal foil driven by the winding mechanism 4 drives the rubber ring 36 and the outer cover wheel 32 to rotate along the axis position of the connecting shaft 33. The fixing rings 39 are symmetrically installed along the center position of the connecting shaft 33. The outer cover wheel 32 is slidably installed on the outside of the connecting shaft 33. The outer cover wheel 32 is located outside the fixing ring 39. A top ring 38 is fixedly installed on the inner wall of the outer cover wheel 32. The outer side of the top ring 38 is a conical surface. A rubber ring 36 is fixedly installed on the outside of the outer cover wheel 32. A top block 37 is slidably installed on the inner wall of the outer cover wheel 32. The opposite surfaces of the top block 37 are arc surfaces, and the opposite surfaces of the top block 37 are slidably adapted to the outer side of the top ring 38. Sleeve blocks 34 are rotatably installed at both ends of the outside of the connecting shaft 33, and an elastic plate 35 is fixedly installed between the sleeve blocks 34. When the metal foil during the transmission process is offset and tilted, through the friction force between the metal foil and the rubber ring 36, the metal foil with an offset trend transfers the offset trend to the outer cover wheel 32 through the rubber ring 36, so that the outer cover wheel 32 transfers the trend to the top ring 38, causing the top ring 38 to have a moving trend. 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 moving trend, the top block 37 has a trend of pressing the rubber ring 36 outward. The elastic plates 35 are symmetrically installed along the axis center position of the sleeve blocks 34.

[0038] The second embodiment, on the basis of the first embodiment, please refer to Figures 3 to 5As shown in the figure, the blank holding mechanism 2 includes a groove frame 201. The top of the outer side of the groove frame 201 is fixedly connected to the first motor 6. A slide seat 204 is slidably installed on the inner wall of the groove frame 201. A cylinder 203 is fixedly installed at the bottom of the slide seat 204. The cylinders 203 are symmetrically installed along the central axis position of the slide seat 204. Positioning columns 202 are fixedly installed on the inner wall of the groove frame 201. The positioning columns 202 are symmetrically installed along the central axis position of the groove frame 201. The inner wall of the slide seat 204 is slidably connected to the outer side of the positioning columns 202. A groove seat 205 is fixedly installed at the top of the slide seat 204. A strip groove is formed at the top of the groove seat 205. An elastic ring 209 is fixedly installed at the strip groove of the groove seat 205. 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 top shaft 211 drives the connecting plate 212 to move downward under the drive of the spring 215, the top shaft 211 drives the connecting plate 212 to press down the metal foil, pressing the two layers of metal foil tightly together. At the same time, the metal foil on one side of the welding passes through the inside of the groove plate 206. At the same time, the two layers of metal foil are tightly pressed and adhered by the rubber wheels 207. A top plate 208 is fixedly installed at the top of the elastic ring 209. The top plate 208 is located directly below the seam welding head 5. An inclined groove is formed at the top of the groove seat 205, and a bottom shaft 210 is rotatably installed at the inclined groove of the groove seat 205.

[0039] The bottom shafts 210 are uniformly installed along the slope of the inclined groove of the groove seat 205. A side plate 214 is fixedly installed on one side of the groove seat 205. A slide rod 213 is slidably installed on the inner wall of the side plate 214. The top end of the slide rod 213 is fixedly installed with a connecting plate 212. A top shaft 211 is fixedly installed on the outer side of the connecting plate 212. The top shafts 211 and the bottom shafts 210 correspond 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 rod 213. A groove plate 206 is fixedly installed on the side of the groove seat 205 away from the side plate 214. A strip groove is formed on the outer side of the groove plate 206. During the welding process, the cylinder 203 drives the slide seat 204 to move upward, so that the pressed metal foil contacts the seam welding head 5. The seam welding head 5 welds the pressed metal foil together. When driving the metal foil to tightly contact the seam welding head 5 upward, the top plate 208 supports at the bottom of the metal foil. At the same time, during the contact process, through the elastic deformation of the elastic ring 209, a certain buffer range is provided during the contact welding process. And wheel grooves are uniformly formed at the top of the groove plate 206, and rubber wheels 207 are rotatably installed at the wheel grooves of the groove plate 206.

[0040] The third embodiment is based on the first and second embodiments. Please refer to Figures 8 to 9As shown in the figure, the rewinding mechanism 4 includes a rotating shaft 41. One end of the rotating shaft 41 is connected to the output end of the second motor 8. A rotating arm 42 is rotatably installed on the outer side of the rotating shaft 41 near the second motor 8. A pressing rod 45 is fixedly installed at the end of the rotating arm 42 away from the rotating shaft 41. A convex ring 43 is fixedly installed on the outer side of the rotating shaft 41. Grooves are evenly arranged on the outer side of the convex ring 43. A rotating cylinder 44 is rotatably installed at the central position on the outer side of the rotating shaft 41. The welded metal foil passes under the pressing rod 45. The wound roller is inserted outside the rotating cylinder 44. The rubber strip 46 outside the rotating cylinder 44 supports and fixes it inside the roller. The second motor 8 drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the convex ring 43 to rotate. By the clamping connection between the convex ring 43 and the convex block 48, the connecting cylinder 47 and the rotating cylinder 44 are driven to rotate together, so that the roller drives the welded material to be rewound and collected. Rubber strips 46 are evenly installed on the outer side of the rotating cylinder 44. Connecting cylinders 47 are fixedly installed at both ends of the rotating cylinder 44. Empty grooves are symmetrically opened on the outer sides of the connecting cylinders 47. Convex blocks 48 are slidably installed at the empty grooves of the connecting cylinders 47. One end of the convex block 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 outer side of the connecting cylinder 47. During the rewinding process, when the positions of the two layers of metal foil are offset, resulting in incorrect welding positions, the material guiding mechanism 3 restricts the movement of the metal foil, and the rotating cylinder 44 is restricted from rotating by the metal foil and the roller. At this time, the convex block 48 transmits the restricting force to the elastic plate 49, causing the elastic plate 49 to deform and continuously changing the clamping position between the convex block 48 and the convex ring 43, so that the rotating cylinder stops rotating. The central position of the inner wall of the elastic plate 49 is fixedly connected to one end of the convex block 48 away from the convex ring 43.

[0041] During use, the worker fixes the two welded metal foil rolls through the material rack 7, so that the metal foil first passes through the material guiding mechanism 3. The material guiding mechanism 3 drives and guides the metal foil and restricts the transmitted metal foil. When the metal foil passes through the material guiding mechanism 3, it enters the material pressing mechanism 2. The material pressing mechanism 2 presses the upper and lower layers of metal foil together, cooperates with the material guiding mechanism 3 to overlap the two layers of metal foil, and applies upward pressure to the bottom of the overlapping metal foil. The first motor 6 drives the roll welding head 5 to rotate. The roll welding head 5 welds the two layers of metal foil through ultrasonic vibration. The welded metal foil passes through the material pressing mechanism 2 and is driven by the second motor 8 to operate the rewinding mechanism 4 to wind up the welded metal foil.

[0042] During the process of guiding the metal foil through the material guiding mechanism 3, the metal foil passes through between the two connecting shafts 33, contacts the upper and lower layers of the metal foil through the rubber ring 36 on the outer side of the outer cover wheel 32. At the same time, the elastic plate 35 drives the sleeve block 34, and the two connecting shafts 33 are driven to approach each other through the sleeve block 34. During the transmission of the metal foil, 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 in the transmission process is offset and tilted, due to the frictional force between the metal foil and the rubber ring 36, the metal foil with an offset tendency transmits the offset tendency to the outer cover wheel 32 through the rubber ring 36, causing the outer cover wheel 32 to transmit the tendency to the top ring 38, resulting in a movement tendency of the top ring 38. Utilizing 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 movement tendency, the top block 37 has a tendency to press the rubber ring 36 outward.

[0043] 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 top shaft 211 drives the connecting plate 212 to move downward under the action of the spring 215, the top shaft 211 drives the connecting plate 212 to press down the metal foil, tightly pressing the two layers of metal foil together. At the same time, the metal foil on one side of the welding passes through the inside of the groove plate 206, and the two layers of metal foil are tightly pressed and closely attached by the rubber wheel 207. During the welding process, the cylinder 203 drives the slide seat 204 to move upward, so that the pressed metal foil contacts the roller welding head 5, and the pressed metal foil is welded together by the roller welding head 5. When driving the metal foil upward to tightly contact the roller welding head 5, the top plate 208 supports at the bottom of the metal foil. At the same time, during the contact process, through the elastic deformation of the elastic ring 209, a certain buffer range is provided during the contact welding process.

[0044] After the metal foil is welded, the welded metal foil passes through below the pressure rod 45, inserts the wound drum outside the rotating cylinder 44, and the rubber strip 46 outside the rotating cylinder 44 supports and fixes it inside the drum. The second motor 8 drives the rotating shaft 41 to rotate, and the rotation of the rotating shaft 41 drives the convex ring 43 to rotate. Utilizing the clamping connection between the convex ring 43 and the convex block 48, the connecting cylinder 47 and the rotating cylinder 44 are driven to rotate together, so that the drum drives the welded material to be wound and collected. At the same time, during the winding process, when the positions of the two layers of metal foil are offset, resulting in a wrong welding position, the material guiding mechanism 3 restricts the movement of the metal foil, and the rotation of the rotating cylinder 44 is restricted by the metal foil and the drum. At this time, the convex block 48 transmits the restricting force to the elastic plate 49, causing the elastic plate 49 to deform and continuously changing the clamping position between the convex block 48 and the convex ring 43, so that the rotating cylinder stops rotating.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the scope of protection of the present invention. Structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
