Description

Technical Field

[0001] The utility model relates to the technical field of soft rib processing, and in particular to soft rib stamping equipment for new energy vehicles and a production line thereof. Background Art

[0002] A flexible copper busbar, also known as a flexible copper busbar, is an electrical conductor made of a soft copper material and used in electrical equipment and systems. Due to its excellent conductivity and flexibility, it is often used in power transmission and distribution. Compared to rigid copper busbars, flexible copper busbars are easier to bend and handle, making them useful in electrical installations that need to adapt to different spaces and configurations.

[0003] The traditional soft copper busbar production process is that the copper and aluminum foils are automatically cut by a cutting machine, and then manually stacked one by one in order. Then, the nickel-added sheets are manually placed on both sides and one end is manually aligned. The clamp is clamped to reserve the position required for welding, and then handed over to another worker for the subsequent welding process. Manual stacking of copper and aluminum foils will cause uneven stacking due to the action of clamping, or manual error. At the same time, the traditional stacking process is complicated and the manual operation efficiency is low, which is not conducive to the mass production of soft connectors.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention and does not constitute any limitation to the present invention. Utility Model Content

[0027] See also Figure 1 and Figure 2 The utility model provides a soft rib stamping equipment for new energy vehicles, including a punching machine 100 and a stamping die 110. The stamping die 110 is installed on the workbench of the punching machine 100 through its lower die. The ejection column 11 of the stamping die 110 is connected to the ejection device of the punching machine 100. The stamping die 110 punches the blank into a soft rib semi-finished product 10 with a convex structure 101 in a single time through the convex structure set in its upper die.

[0028] Specifically, in an embodiment of the present invention, the stamping equipment includes a punching machine 100 and a stamping die 110, and the stamping die 110 is a tool for punching the blank on the punching machine 100. Commonly, the stamping die 110 generally includes an upper die, a lower die and an ejection mechanism, etc. The upper die is the upper part of the stamping die 110, usually including a punch or a punch, which is used to stamp, cut or shape the blank installed therein. The lower die is the lower part of the die, usually including a die or a die base, which is used to support and position the workpiece, i.e. the blank, and receive the impact from the upper die. The ejection mechanism, such as the ejection column 11 structure, is used to push the stamped workpiece, i.e. the soft row semi-finished product 10, out of the die to prevent the workpiece from getting stuck in the die. Similarly, the stamping die 110 also includes a positioning device, a guide system, etc., which are not described here.

[0029] More specifically, the stamping process of the flexible copper busbar, also known as the flexible busbar, includes placing a copper foil strip as raw material into a punch press 100, and punching and blanking the material through a punching die 110 in the punch press 100 to form a specific copper foil sheet, also known as the flexible busbar semi-finished product 10, and then ejecting the copper foil sheet of the flexible busbar semi-finished product 10 from the stamping die 110 through an ejector pin 11. When the stamping die 110 extrude the blank copper foil sheet into the flexible busbar semi-finished product 10 copper foil sheet through the action between the upper die and the lower die, a corresponding protruding structure (not shown in the drawings) can be provided on the surface of the blank copper foil sheet acting on the upper die to form a corresponding convex structure 101 on the flexible busbar semi-finished product 10.

[0030] In this way, by punching out a copper foil sheet with a convex structure 101 on the copper foil strip in the stamping die 110 as a soft bus semi-finished product 10, that is, by designing the convex structure 101 on the soft bus semi-finished product 10, the multi-layer soft bus semi-finished product 10 copper foil sheets can be stacked in an orderly manner, avoiding misalignment between multiple soft bus semi-finished products 10 in the stacked state, thereby improving the forming accuracy and yield rate of the soft bus semi-finished product 10 in the subsequent process. At the same time, the stacked soft bus semi-finished product 10 copper foil sheets can also be circulated as a whole between the processes, avoiding the problem that the traditional soft bus semi-finished product 10 copper foil sheets are scattered and inconvenient to circulate after stamping and blanking.

[0031] See also Figure 1 In one embodiment, the punch press 100 further includes a clamping chamber 12, which is located below the ejector pin 11 and communicates with the space above the ejector pin 11. The bottom of the clamping chamber 12 extends through the external space below the punch press 100. The cross-sectional profile of the clamping chamber 12 matches the profile of the soft-row semi-finished product 10, and the soft-row semi-finished product 10 moves along the clamping chamber 12 under the action of the ejector pin 11. The height of the clamping chamber 12 is greater than the thickness of a single soft-row semi-finished product 10.

[0032] Specifically, in an embodiment of the present invention, the clamping cavity 12 is used to accommodate the soft ribbed semi-finished product 10 pushed out by the ejection column 11. When the fallen soft ribbed semi-finished product 10 falls into the clamping cavity 12 of the mold, the cross-sectional profile of the clamping cavity 12 is set to match the copper foil of the soft ribbed semi-finished product 10 (for example, the inner profile of the clamping cavity 12 can be set to match the outer profile of the copper foil of the soft ribbed semi-finished product 10, or the width of the clamping cavity 12 can be matched with the width of the copper foil of the soft ribbed semi-finished product 10, so that the contact between the two is in a clamping state), that is, the copper foil of the soft ribbed semi-finished product 10 will be clamped in it after falling into the clamping cavity 12 and will not continue to fall freely, so as to cooperate with the action of the ejection column 11 to further press and lock the copper foil of the soft ribbed semi-finished product 10 in the clamping cavity 12. In this way, when the required number of semi-finished copper foil sheets 10 for the soft bus has accumulated in the clamping cavity 12, as the ejection column 11 continues to push out the semi-finished copper foil sheets 10 for the soft bus, the semi-finished copper foil sheets for the soft connection will be pushed out of the clamping cavity 12. The height of the clamping cavity 12 is used to determine the number of semi-finished copper foil sheets 10 for the soft bus, thereby controlling the number of semi-finished copper foil sheets 10 for the soft bus that circulate as a whole and improving the batch production efficiency of the soft bus.

[0033] See also Figure 1 In one embodiment, a conveyor belt 400 is further arranged below the punch press 100 , and the conveyor belt 400 corresponds to the bottom outlet of the clamping chamber 12 .

[0034] Specifically, in the embodiment of the present invention, a punch press 100 with a support structure is used, so that a conveyor belt 400 can be arranged between the supports at the bottom of the punch press 100, that is, at the exit position of the through-space connecting the clamping cavity 12 to the outside of the punch press 100. In this way, after the semi-finished copper foil of the flexible connector is pushed out of the clamping cavity 12, it will pass through the through-space below it and fall onto the conveyor belt 400 below the stamping die 110, and then be transported to the subsequent process for further processing.

[0035] It should be noted that, combined with the height of the clamping cavity 12, the number of semi-finished flexible rectifier 10 copper foil sheets that can be pushed out of the clamping cavity 12 at one time can be selectively controlled, that is, the number of semi-finished flexible rectifier 10 copper foil sheets that can be batch processed. In this way, combined with the batch processing quantity of the semi-finished flexible rectifier 10 copper foil sheets in the subsequent process, the semi-finished flexible rectifier 10 copper foil sheets can be efficiently processed in the subsequent process after the stamping is completed, further improving the batch production efficiency of the flexible rectifier.

[0036] See also Figure 1 In one embodiment, the punch press 100 further includes a beveled pressure plate 13. One end of the beveled pressure plate 13 contacts the top of the ejector pin 11, and the other end is connected to the cylinder 14 of the ejection device. The beveled pressure plate 13 pushes the ejector pin 11 to move under the traction of the cylinder 14. The contact portion of the beveled pressure plate 13 and the ejector pin 11 includes corresponding horizontal sections 131 and inclined sections 132. The lengths of the horizontal sections 131 and the inclined sections 132 on the beveled pressure plate 13 are greater than their lengths on the ejector pin 11, and the height of the inclined section 132 on the beveled pressure plate 13 is greater than its height on the ejector pin 11.

[0037] Specifically, in the embodiment of the present invention, a beveled pressure plate 13 is designed on the punching machine 100, that is, the stamping die 110, and the beveled pressure plate 13 is pulled to move in conjunction with the telescopic action of the cylinder 14, so that the beveled pressure plate 13 squeezes the ejector column 11 to push the copper foil of the soft row semi-finished product 10 out of the stamping die 110. The ejector column 11 in the stamping die 110 can be connected to the ejection device of the punching machine, such as the cylinder 14, through the beveled pressure plate 13. When the beveled pressure plate 13 pushes the ejector column 11 to perform the stamping action and move, it is achieved by opening a corresponding bevel on the beveled pressure plate 13. The bevel includes a connected horizontal section 131 and an inclined section 132. The difference in height between the horizontal section 131 connected at both ends of the inclined section 132 and the horizontal side surface of the beveled pressure plate 13 corresponds to the stroke range of the ejector column 11.

[0038] More specifically, during the initial stage of the movement of the beveled pressure plate 13 by the cylinder 14, that is, when the contact surface between the beveled pressure plate 13 and the ejector pin 11 moves from the horizontal section 131 to the inclined section 132, the contact between the ejector pin 11 and the beveled pressure plate 13 transitions from the horizontal section 131 to the inclined section 132. As the cylinder 14 moves the beveled pressure plate 13 in the middle stage of its movement, that is, when the contact surface between the beveled pressure plate 13 and the ejector pin 11 is in the inclined section 132, the ejector pin 11 and the beveled pressure plate 13 completely contact each other through the inclined section 132. Finally, during the final stage of the movement of the beveled pressure plate 13 by the cylinder 14, that is, when the contact surface between the beveled pressure plate 13 and the ejector pin 11 moves from the inclined section 132 to the horizontal side surface, the contact between the ejector pin 11 and the beveled pressure plate 13 transitions from the inclined section 132 to the horizontal side surface. It is easy to imagine that the reset process of the ejector column 11 is to release the reset stroke of the ejector column 11 by moving the inclined pressure plate 13 in the reverse direction. The ejector column 11 can be driven to rise and reset by installing corresponding reset elastic members (not shown in the drawings), which will not be elaborated here.

[0039] In this way, by arranging corresponding horizontal sections 131 and inclined sections 132 on the bevel pressure plate 13 and the ejector column 11, the bevel pressure plate 13 is entirely on the contact surface of the horizontal section 131 or the inclined section 132 during the process of pushing the ejector column 11, thereby maintaining the stability of the bevel pressure plate 13 in pushing the ejector column 11.

[0040] See also Figure 3 In one embodiment, the present invention further provides a flexible busbar production line for new energy vehicles, comprising the punch press 100 described above. Furthermore, the line also includes a nickel sheet positioning tool 200 and a polymer diffusion welding machine 300 sequentially arranged on the line.

[0041] Specifically, in an embodiment of the present invention, a punching machine 100, a positioning nickel stacking tool 200, and a polymer diffusion welding machine 300 are arranged in sequence and connected by a conveyor belt 400 to form a soft rib production line. The soft rib semi-finished product 10 processed in the punching machine 100 is transported to the positioning nickel stacking tool 200 via the conveyor belt 400. Then, the soft rib semi-finished product 10 on the conveyor belt 400 is manually picked up and placed into the positioning nickel stacking tool 200 and the corresponding nickel sheet is added. After the process is completed, it is returned to the conveyor belt 400 and transported to the polymer diffusion welding machine 300. Finally, the positioning nickel stacking tool 200 with the soft rib semi-finished product 10 is manually placed into the corresponding card slot of the polymer diffusion welding machine 300 for welding and forming to form the desired finished product. This improves the production efficiency of the soft rib finished product.

[0042] In summary, the utility model provides a soft ribbed stamping equipment for new energy vehicles. By punching out a soft ribbed semi-finished product with a convex structure on the blank in the stamping equipment, multiple layers of soft ribbed semi-finished products can be stacked in an orderly manner to avoid dislocation, thereby improving the precision and yield rate of the soft ribbed semi-finished product forming. At the same time, the stacked soft ribbed semi-finished products can also be easily circulated as a whole. The soft ribbed semi-finished products formed in the stamping equipment are transported to the conveyor belt below, and the soft ribbed semi-finished products are transported to the positioning nickel stacking tooling, the nickel sheet is installed to the corresponding position of the soft connection semi-finished product, and finally the soft ribbed semi-finished product is welded to the finished product by polymer diffusion welding graphite, thereby improving the production efficiency of the soft ribbed finished product.
