Description

Technical Field

[0001] This invention relates to the field of punching machines, specifically a chip copper busbar bending and punching integrated machine. Background Technology

[0002] Copper busbars, as a high-current conductive product that bears the heavy responsibility of transmitting current and connecting electrical equipment in circuits, are widely used in electrical engineering fields such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and busbar trunking. They also play a key role in ultra-high current electrolytic smelting projects such as metal smelting, electrochemical electroplating, and chemical caustic soda production. In chip manufacturing, the chip copper busbar is an important component connecting the chip to the external circuit. Its processing quality directly affects the chip performance and equipment stability. To meet the high precision requirements of chip manufacturing, copper busbars often need to undergo fine processing such as bending and punching.

[0003] However, the existing adjustment mechanisms are crudely designed, mostly using manual screw adjustment or simple gear and rack adjustment methods, resulting in low adjustment accuracy. During the punching process, there is a lack of an effective copper busbar fixing structure, and the copper busbar is prone to shaking and displacement under the impact of punching pressure. This not only reduces the punching quality but may also cause safety hazards. Furthermore, it is impossible to continue punching the copper busbar after changing its bending angle. Summary of the Invention

[0004] This invention provides an integrated machine for bending and punching copper busbars for chips, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A chip copper busbar bending and punching integrated machine includes a bending mold, a bending mechanism, a support structure, a limiting plate group, and a conveying component disposed within the bending and punching integrated machine. The bending mold and the conveying component are respectively disposed on the left and right sides of the support structure. The limiting plate group is disposed on the upper side of the support structure, and the bending mechanism is disposed close to the bending mold. A robot arm is also provided on the side of the conveying component to convey the copper busbar between the support structure and the limiting plate group through the conveying component or to clamp the copper busbar between the support structure and the limiting plate group through the robot arm.

[0007] The bending die includes a swing plate and an arc-shaped cylinder disposed on the back of the swing plate. The swing plate is fixed on the output shaft of a motor and is driven to rotate by the motor. The surface of the swing plate is provided with a first mounting groove and a second mounting groove. A punching template is disposed in the first mounting groove and a magnetic suction plate is disposed in the second mounting groove. The punching template is attracted and fixed by the magnetic suction plate. The arc-shaped cylinder is driven to extend and retract its output shaft by an external air compressor. The output shaft of the arc-shaped cylinder has an arc-shaped structure and a punching plate is disposed on the output shaft of the arc-shaped cylinder so that the output shaft of the arc-shaped cylinder is driven to press the punching plate along the punching template.

[0008] The bending mechanism includes a bending wheel and a motor for driving the bending wheel to rotate. A bending rod for twisting the copper busbar is provided on the side of the bending wheel near the bending die.

[0009] There is a gap between the limiting plate assembly and the supporting structure for the copper busbar to pass through, and the limiting plate assembly is driven to rise and fall by a cylinder installed on the bending and punching machine, so as to adjust the gap by driving the limiting plate assembly to rise and fall by the cylinder.

[0010] In a preferred embodiment, the limiting plate assembly is disposed above the support structure, and the side of the limiting plate assembly has a notch that extends to the upper end of the limiting plate assembly. The limiting plate assembly consists of a first baffle and a second baffle, which are respectively disposed on the left and right sides of the support structure. The first baffle is connected to the output shaft of the cylinder and extends above the conveying assembly. The surface of the first baffle away from the conveying assembly has a raised portion, so that the first baffle can be driven to move downward by the cylinder. The copper busbar on the support structure is fixed by the raised portion of the surface of the first baffle.

[0011] In a preferred embodiment, the bending wheel has a groove on its surface and a bending rod is also provided in the groove. The bending wheel has a threaded rod that passes through the groove and is threadedly connected to the bending rod. The bending rod can be rotated to make the bending rod slide up and down in the groove. The side of the bending wheel away from the groove is provided with a meshing gear, and a gear that meshes with the meshing gear is provided on an output shaft of the motor.

[0012] The upper end of the bent rod is provided with a stop plate extending towards the baffle. When the stop plate abuts against the upper end surface of the baffle, the lower end surface of the bent rod and the lower end surface of the baffle are at the same horizontal plane.

[0013] In a preferred embodiment, the support structure includes a support plate and a fixing plate. The support plate is fixed inside the bending and punching machine by the support plates on both sides. There is a gap between the fixing plate on the side near the arc-shaped cylinder and the arc-shaped cylinder. When the swing plate drives the arc-shaped cylinder to swing, the arc-shaped cylinder does not collide with the fixing plate.

[0014] In a preferred embodiment, the conveying assembly includes a conveyor belt, transmission wheels, a second motor, and a drive wheel. The transmission wheels are symmetrically arranged, the conveyor belt is sleeved over the two transmission wheels, and the drive wheel is mounted on the output shaft of the second motor. The drive wheel and one of the transmission wheels form a belt drive connection.

[0015] In a preferred embodiment, the punching template is provided with a retaining plate on both sides, and a retaining groove is provided on the surface of the swing plate corresponding to the retaining plate. The punching template is inserted into the mounting groove from the outside to the inside, and the retaining plate abuts against the surface of the retaining groove.

[0016] The punching template has a chip removal groove extending to the lower end of the punching template. The surface of the punching template has multiple holes corresponding to the perforated protrusions on the surface of the punching plate. These holes are connected to the chip removal groove, and the chip removal groove has a protrusion at the corresponding position of each hole.

[0017] Compared with existing technologies, this technical solution has the following advantages:

[0018] When the copper busbar is conveyed onto the support structure, baffle one moves downwards, its raised surface tightly pressing against the edge of the copper busbar. This raised structure increases contact pressure, preventing deformation of the thin copper busbar and preventing lateral displacement due to punching or torsional forces during punching and bending. This solves the swaying problem caused by the lack of effective fixation in traditional equipment. Simultaneously, baffle one extends above the conveying assembly, allowing for pre-positioning of the conveying copper busbar. Baffle two is fixed to the other side of the support structure, forming a symmetrical layout with baffle one. Its inner edge fits against the other edge of the copper busbar, restricting displacement in the width direction. For irregularly shaped or pre-bent copper busbars, the straight edge of baffle two can serve as a reference, working in conjunction with the clamping force of baffle one to form a three-dimensional constraint of "left-right clamping and top-bottom pressing," ensuring the stability of the copper busbar during processing.

[0035] like Figures 1 to 9 As shown, the present invention proposes a chip copper busbar bending and punching integrated machine, including a bending mold 1, a bending mechanism 2, a support structure 3, a limiting plate group 4 and a conveying component 5 disposed in the bending and punching integrated machine. The bending mold 1 and the conveying component 5 are respectively disposed on the left and right sides of the support structure 3. The limiting plate group 4 is disposed on the upper side of the support structure 3, and the bending mechanism 2 is disposed close to the bending mold 1. The side of the conveying component 5 is also provided with a robot 6, so as to convey the copper busbar between the support structure 3 and the limiting plate group 4 through the conveying component 5 or to clamp the copper busbar between the support structure 3 and the limiting plate group 4 through the robot 6.

[0036] The bending mold 1 includes a swing plate 11 and an arc-shaped cylinder 12 disposed on the back of the swing plate 11. The swing plate 11 is fixed on the output shaft of a motor and is driven to rotate by the motor. The surface of the swing plate 11 is provided with a first mounting groove 111 and a second mounting groove 113. A punching template 112 is disposed in the first mounting groove 111 and a magnetic suction plate 114 is disposed in the second mounting groove 113. The punching template 112 is attracted and fixed by the magnetic suction plate 114. The arc-shaped cylinder 12 is driven to extend and retract its output shaft by an external air compressor. The output shaft of the arc-shaped cylinder 12 has an arc-shaped structure and a punching plate 13 is disposed on the output shaft of the arc-shaped cylinder 12 so that the output shaft of the arc-shaped cylinder 12 is driven to press the punching plate 13 along the punching template 112.

[0037] As described above, after the copper busbar is placed between the support structure 3 and the limiting plate group 4 by the conveying component 5 or the robot arm 6, the limiting plate group 4 is lowered under the drive of the cylinder 41, and together with the support structure 3, clamps the copper busbar to ensure no shaking during processing; the swing plate 11 is rotated to a preset angle under the drive of the motor, so that the punching template 112 (fixed by the magnetic suction plate 114) is aligned with the area to be punched on the copper busbar; the external air compressor drives the arc-shaped cylinder 12, and its arc-shaped output shaft extends and retracts along the preset arc, driving the punching plate 13 to move towards the punching template 112 in an arc-shaped trajectory. Through the squeezing and cooperation between the punching plate and the template, the processing of arc-shaped holes or holes distributed along the arc path is completed on the copper busbar.

[0038] According to the appendix Figure 8 As shown, the limiting plate group 4 is disposed above the support structure 3, and the side of the limiting plate group 4 is provided with a notch that extends to the upper end of the limiting plate group 4. The limiting plate group 4 is composed of a first baffle 101 and a second baffle 102. The first baffle 101 and the second baffle 102 are respectively disposed on the left and right sides of the support structure 3. The first baffle 101 is connected to the output shaft of the cylinder 41. The first baffle 101 extends above the conveying component 5, and the surface of the first baffle 101 away from the conveying component 5 is provided with a raised part, so that the cylinder 41 can drive the first baffle 101 to move downward. The copper busbar fixed on the support structure 3 is fixed by the raised part on the surface of the first baffle 101. The first baffle 101 is connected to the output shaft of the cylinder 41 and can be raised and lowered under the drive of the cylinder. When the copper busbar is conveyed onto the support structure 3, baffle 101 moves downward, and its raised surface tightly presses against the edge of the copper busbar. This raised structure increases contact pressure, preventing deformation of the thin copper busbar and preventing lateral displacement due to punching or torsional forces during punching and bending, thus solving the swaying problem caused by the lack of effective fixation in traditional equipment. Simultaneously, baffle 101 extends above the conveying assembly 5, allowing for pre-positioning of the conveying copper busbar. Baffle 2 102 is fixed to the other side of the support structure 3, forming a symmetrical layout with baffle 101. Its inner edge fits against the other edge of the copper busbar, restricting displacement in the width direction. For irregularly shaped or pre-bent copper busbars, the straight edge of baffle 2 102 can serve as a reference, working in conjunction with the clamping force of baffle 101 to form a three-dimensional constraint of "left and right clamping + top and bottom pressing," ensuring the stability of the copper busbar's posture during processing.

[0039] Copper busbars often need to be pre-bent or designed with irregular shapes (such as those with local protrusions or curved sections). When the robotic arm 6 picks up such copper busbars, the notch can accommodate the protruding parts or bent sections of the copper busbar, avoiding interference with the limiting plate group 4. For example, for a copper busbar that has already been bent at 90°, the robotic arm 6 can extend its vertical section above the support structure 3 through the notch, while the horizontal section rests on the upper surface of the limiting plate group 4, achieving stable placement.

[0040] Furthermore, the bending mechanism 2 includes a bending wheel 21 and a motor 22 for driving the bending wheel 21 to rotate. The bending wheel 21 has a bending rod 211 for twisting the copper busbar on the side near the bending die 1. There is a gap between the limiting plate assembly 4 and the supporting structure 3 for the copper busbar to pass through. The limiting plate assembly 4 is driven to rise and fall by a cylinder 41 mounted on the bending and punching integrated machine, so as to adjust the gap by driving the limiting plate assembly 4 to rise and fall via the cylinder 41. Figure 4 As shown, the bending wheel 21 has a groove 213 on its surface, and the bending rod 211 also has a groove 213 inside the groove 213. The bending wheel 21 has a threaded rod 212 that passes through the groove 213 on its surface. The threaded rod 212 passes through the bending rod 211 and forms a threaded connection with it, so that the bending rod 211 can slide up and down in the groove 213 by rotating the threaded rod 212. The side of the bending wheel 21 away from the groove 213 has a meshing gear 214. The output shaft of the motor 22 has a gear that meshes with the meshing gear 214. The upper end of the bending rod 211 has a stop plate 2111 that extends toward the baffle 101. When the stop plate 2111 abuts against the upper end surface of the baffle 101, the lower end surface of the bending rod 211 and the lower end surface of the baffle 101 are at the same level.

[0041] Motor 22 meshes with the bending wheel 21's meshing gear 214 via its output shaft gear, driving the bending wheel 21 to rotate and thus achieving the twisting and bending of the copper busbar by the bending rod 211. The slide groove 213 provides an axial sliding track for the bending rod 211. When the threaded rod 212 rotates, the threaded transmission drives the bending rod 211 to rise and fall along the slide groove 213, precisely adjusting its contact height with the copper busbar to accommodate different thicknesses of chip copper busbars. This structure solves the problem of low precision in traditional manual screw adjustment. The threaded rod 212, in conjunction with the guide constraint of the slide groove 213, avoids wobbling and offset during adjustment. Simultaneously, the swing plate 11 can be rotated by the motor to change its angle. After the copper busbar is bent to a preset angle by the bending rod 211, the swing plate 11 rotates to adapt to the bent copper busbar's posture, aligning the punching template 112 with the area to be processed, achieving continuous bending and punching operations. This overcomes the defect of traditional equipment that cannot continue punching holes in bent copper busbars.

[0042] Furthermore, as shown above, the abutment plate 2111 abuts against the upper end face of the baffle plate 101, ensuring that the lower end face of the bent rod 211 is flush with the lower end face of the baffle plate 101, forming a mechanical limiting reference. This design solves the problem of the lack of precise positioning in traditional adjustment mechanisms: when the threaded rod 212 is rotated to adjust the height of the bent rod 211, the contact between the abutment plate 2111 and the baffle plate 101 can quickly calibrate the initial position, avoiding the cumulative error of manual adjustment, and ensuring that the bending reference of copper busbars of different thicknesses is consistent. At the same time, the limiting function ensures the repeatability of adjustment: when changing the copper busbar specifications multiple times, there is no need for repeated measurements; the standard position can be restored simply by limiting the abutment plate 2111, reducing adjustment time.

[0043] Furthermore, the support structure 3 includes a support plate 31 and a fixing plate 32. The support plate 31 is fixed in the bending and punching machine by the support plates 31 on both sides. There is a gap between the fixing plate 32 on the side close to the arc cylinder 12 and the arc cylinder 12. When the swing plate 11 drives the arc cylinder 12 to swing, the arc cylinder 12 does not abut against the fixing plate 32.

[0044] Furthermore, the conveying assembly 5 includes a conveyor belt 51, a transmission wheel 52, a second motor 53, and a drive wheel 54. The transmission wheels 52 are symmetrically arranged, the conveyor belt 51 is sleeved on the two transmission wheels 52, and the drive wheel 54 is mounted on the output shaft of the second motor 53. The drive wheel 54 and one of the transmission wheels 52 form a belt drive connection.

[0045] Furthermore, the punching template 112 is provided with a clamping plate 1121 on both sides, and a clamping groove 115 is provided on the surface of the swing plate 11 corresponding to the clamping plate 1121. The punching template 112 is inserted into the mounting groove 111 from the outside to the inside, and the clamping plate 1121 abuts against the surface of the clamping groove 115.

[0046] The punching template 112 has a chip removal groove 1122 extending to the lower end of the punching template 112. The surface of the punching template 112 has a plurality of holes 1123 corresponding to the perforated protrusions on the surface of the punching plate 13. The holes 1123 are connected to the chip removal groove 1122, and the chip removal groove 1122 has a protrusion 1124 at the corresponding position of each hole 1123.

[0047] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
