Description

Technical Field

[0001] This utility model relates to the field of soft copper bar technology, and in particular to a feeding component and a soft copper bar polymer diffusion welding machine. Background Technology

[0002] In the field of new energy battery manufacturing, soft copper conductive sheets are key connecting components, and their welding quality directly affects the performance and safety of the battery. Traditional welding processes rely heavily on manual operation for the feeding, positioning, and clamping of soft copper sheets, presenting several significant problems: manual placement of each sheet is difficult to match the high-speed production demands of automated production lines; manual positioning easily leads to copper sheet misalignment or tilting, affecting welding accuracy; in high-temperature welding environments, manual operation may cause burns or mechanical injuries; multiple operators are required, and the high rate of welding defects increases subsequent rework costs. While some existing automated devices attempt to achieve feeding via robotic arms or conveyor belts, they generally suffer from complex structures, insufficient control precision, or inability to simultaneously complete clamping and positioning. Therefore, there is an urgent need for an integrated, high-precision, and safe automated feeding and clamping device to meet the specific requirements of the soft copper sheet polymer diffusion welding process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as low device efficiency (manual placement of copper bars piece by piece is difficult to match the high-speed production requirements of automated production lines), poor consistency (manual positioning can easily cause copper bars to shift or tilt, affecting welding accuracy), safety hazards (manual operation may cause burns or mechanical injuries in high-temperature welding environments), and high cost (requiring multiple operators and increasing the cost of subsequent rework due to high welding defect rates). Therefore, this invention proposes a feeding component and a polymer diffusion welding machine for soft copper bars.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding assembly includes a placement plate with side blocks fixed to both sides. The top of each side block has a groove communicating with a horizontal groove on the top of the placement plate. The assembly also includes:

[0006] The placement box is fixed to the top of the side block, and the bottom has a clearance hole to accommodate multiple soft copper bars stacked on top of each other.

[0007] The top plate is fixed to one side of the placement box, and the bottom is provided with an ejection assembly. The ejection assembly includes a bidirectional lead screw, a symmetrical moving plate driven by a servo motor, and a push plate fixed to the moving plate. The push plate forms a sliding fit with the clearance hole.

[0008] The clamping assembly is symmetrically arranged on both sides of the placement box, and includes an L-shaped plate that slides along the slide groove and a tension spring that connects the slider and the top of the slide groove;

[0009] The linkage mechanism includes a crossbar and a diagonal bar fixed to the movable plate, wherein the inclined working surface of the diagonal bar forms a contact fit with the top of the L-shaped plate;

[0010] When the bidirectional lead screw rotates, the push plate pushes the soft copper bar out of the clearance hole into the transverse groove, and at the same time the inclined rod presses down on the L-shaped plate to achieve automatic clamping. When the servo motor reverses, the tension spring resets the L-shaped plate.

[0011] As a further improvement to the above technical solution:

[0012] The launch component includes:

[0013] Two fixing plates are symmetrically fixed to both sides of the bottom of the top plate;

[0014] The bidirectional lead screw is rotatably supported on a fixed plate at both ends;

[0015] The servo motor is fixed to the outside of one of the fixed plates, and its output shaft is coaxially connected to the bidirectional lead screw.

[0016] In the clamping assembly:

[0017] The chute extends perpendicularly to the material ejection direction of the placement box;

[0018] The horizontal section of the L-shaped plate extends to the outside of the placement box, and the vertical section is provided with a pressing surface that contacts the soft copper bar.

[0019] In the linkage mechanism:

[0020] The axis of the crossbar is parallel to the axis of the double-acting lead screw;

[0021] The inclined angle of the diagonal rod is 30°-60°, and its end is provided with an arc transition part that contacts the top plane of the L-shaped plate. The cross-sectional shape of the clearance hole forms a clearance fit with the outline of the soft copper bar, and the clearance is controlled within the range of 0.1-0.5mm. The servo motor is connected to the bidirectional lead screw through a coupling to transmit torque, and a protective cover is provided on the outside of the coupling. The preload of the tension spring is adjustable, and its lower end is connected to the slider through a threaded connector to form a detachable connection. The radius of curvature R of the arc transition part satisfies R≥2mm, and the surface is hardened to form a wear-resistant layer.

[0022] A soft copper polymer diffusion welding machine, comprising:

[0023] As mentioned above, the feeding components;

[0024] The supporting shell is fixed to the polymer diffusion welding machine body at one end;

[0025] A reinforcing plate is fixed to the side of the supporting shell and extends to the bottom of the placement plate, and its top is provided with a guide slope corresponding to the transverse groove.

[0026] In this application, during use, multiple soft copper bars are placed inside the placement box and stacked one on top of the other. During welding, the soft copper bar at the bottom falls onto the top of the side block and is located inside the clearance hole. At this time, the servo motor can be started. The output shaft of the servo motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives two moving plates to move closer to each other. The two moving plates drive two pushing plates to move closer to each other. The two pushing plates enter the clearance hole and push out the soft copper bar. The soft copper bar enters the transverse groove.

[0027] At the same time, as the moving plate moves laterally, it can drive the crossbar to move laterally, and the crossbar drives the diagonal bar to move laterally. The inclined surface of the diagonal bar will press the L-shaped plate downward, and the L-shaped plate will drive the slider to move down. The slider will stretch the tension spring. At this time, the L-shaped plate moves down, which can press down the protruding soft copper bar, thus facilitating the welding process.

[0028] After the polymer diffusion welding machine body completes the welding, the servo motor is restarted. The output shaft of the servo motor reverses, and the L-shaped plate moves upward under the tension of the tension spring. The push plate moves to one side of the clearance hole again, and the new soft copper bar falls into the interior of the clearance hole. At this time, the welded soft copper bar can be taken out to facilitate the next welding process.

[0029] Beneficial effects:

[0030] The system employs a stacked placement box and a servo motor-driven bidirectional screw mechanism to automatically eject soft copper bars layer by layer, completing the feeding process in a single action and improving work efficiency.

[0031] The precise fit between the push plate and the clearance hole reduces the lateral positioning error of the copper bar, meeting the requirements for high-precision welding.

[0032] Through the linkage mechanism of the inclined bar-L-shaped plate and the spring reset design, the clamping action is automatically completed at the same time as the copper bar is pushed out, eliminating the need for manual intervention.

[0033] The clamping force is automatically adjusted by the mechanical structure to avoid excessive pressure causing deformation of the copper bar or insufficient pressure causing poor welding, thereby improving the welding yield.

[0034] The fully enclosed welding area, combined with the automated feeding process, allows operators to monitor remotely only, completely eliminating the risk of high-temperature burns and mechanical pinching injuries.

[0035] After welding is completed, the servo motor can be reversed to reset, and the new copper bar will automatically fall to the welding position, achieving a seamless connection between "feeding-welding-removal". Attached Figure Description

A push plate 17 is fixedly connected to one side of the movable plate 10. A clearance hole 20 is provided at the bottom of the placement box 7. The push plate 17 is used in conjunction with the clearance hole 20 to place multiple soft copper bars inside the placement box 7 and stack them up and down. When welding, the soft copper bar at the bottom falls to the top of the side block 9 and is located inside the clearance hole 20. At this time, the servo motor 2 can be started. The output shaft of the servo motor 2 drives the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 drives the two movable plates 10 to move closer to each other. The two movable plates 10 drive the two push plates 17 to move closer to each other. The two push plates 17 enter the clearance hole 20 and push out the soft copper bar. The soft copper bar enters the transverse groove 8.

[0045] Both sides of the placement box 7 are provided with clamping components for pressing the soft copper bar. The clamping components include a slide groove 13 on one side of the placement box 7. A slider 16 is slidably connected inside the slide groove 13.

An L-shaped plate 15 is fixedly connected to one side of the slider 16. At the same time, when the moving plate 10 moves laterally, it can drive the crossbar 18 to move laterally. The crossbar 18 drives the diagonal bar 19 to move laterally. The inclined surface of the diagonal bar 19 presses the L-shaped plate 15 downward. The L-shaped plate 15 drives the slider 16 to move downward. The slider 16 stretches the tension spring 14. At this time, the L-shaped plate 15 moves downward, which can press the protruding soft copper bar, thereby facilitating the welding process.

The diagonal bar 19 abuts against the top of the L-shaped plate 15. After welding is completed by the polymer diffusion welding machine body 6, the servo motor 2 is started again. The output shaft of the servo motor 2 reverses, and the L-shaped plate 15 moves upward under the tension of the tension spring 14. The pushing plate 17 moves again to one side of the clearance hole 20, and the new soft copper bar falls into the interior of the clearance hole 20. At this time, the welded soft copper bar can be taken out to facilitate the next welding process.
