Description

Technical Field

[0001] This utility model relates to the field of copper busbar processing technology, specifically a device for flattening the negative electrode of a DC input copper busbar. Background Technology

[0002] Traditional DC input copper busbars typically have a circular or rectangular cross-section for the negative terminal. However, with the increasing power density requirements of power systems, the traditional shape of the copper busbar results in insufficient contact area when connected to other electrical components. This leads to increased contact resistance, causing heat generation, reducing power transmission efficiency, and potentially posing safety hazards. To solve this problem, the end of the copper busbar's negative terminal is flattened, forming a flat structure. This effectively increases the contact area between the end and the connector, reduces contact resistance, and improves conductivity.

[0003] In the prior art, such as the flattening device for processing low-voltage switch components as described in patent number CN218503135U, there is a support frame, a conveyor belt, a part body, a first mounting plate, and a second mounting plate. Two sets of mounting grooves are provided on both sides of the conveyor belt. A first cylinder drives a first driving block to move within the mounting groove via a first connecting assembly. The first driving block can drive a first flattening rod in the first groove to flatten the upper end of the first pin. A second cylinder drives a second driving block to move within the mounting groove via a second connecting assembly. The second driving block can drive a second flattening rod in the second groove to flatten the lower end of the second pin. Through the first flattening mechanism and the second flattening mechanism, the first and second pins on the part body can be flattened quickly.

[0004] While the aforementioned patents can flatten parts, some problems remain. External interference during transport can easily cause parts to shift. This shift leads to inaccurate positioning of the parts upon entering the flattening station, affecting the precision and quality of the flattening process. Therefore, this invention provides a DC input copper busbar negative electrode flattening device. Utility Model Content

[0011] Preferably, a sprocket and chain assembly is provided on one side of the outer wall of the conveyor frame, one end of the outer wall of a group of conveying rollers extends through the outer wall of the conveyor frame, and the group of conveying rollers are fixedly connected by the sprocket and chain assembly.

The output shaft of the first motor passes through the outer wall of the L-shaped plate and is fixedly connected to the sprocket and chain assembly.

[0012] Preferably, two third slide rods are fixedly installed on the inner wall of the mounting shell, and the two sliders are slidably connected to the two third slide rods. The conveyor frame is fixedly installed on the top of the base plate.

[0013] Preferably, a second motor is fixedly installed at the bottom of the mounting shell, the output shaft of the second motor passes through the inner wall of the mounting shell and is fixedly installed on a rotating plate, and connecting plates are rotatably installed at both ends of the outer wall of the rotating plate, and one end of the outer wall of the two connecting plates is rotatably connected to two moving plates respectively. Beneficial effects

[0014] This invention provides a device for flattening the negative electrode of a DC input copper busbar. Compared with the prior art, it has the following advantages:

[0015] 1. This DC input copper busbar negative electrode flattening device, when feeding copper busbars, first starts the first motor. The output shaft of the first motor drives the sprocket and chain assembly to rotate, which in turn drives a set of conveyor rollers to rotate synchronously. The copper busbar to be flattened is placed on the conveyor rollers, and the rotation of the conveyor rollers achieves the conveying of the copper busbar. At the same time, the second motor starts, and its output shaft drives the rotating plate to rotate. The connecting plates at both ends of the rotating plate rotate accordingly. Since the connecting plate is rotatably connected to the moving plate, and the slider at the bottom of the moving plate is slidably set in the mounting housing, the two sets of limit rollers on both sides can be brought closer to each other. The two sets of limit rollers contact the copper busbar to correct its deviation and prevent the copper busbar from shifting during the conveying process, ensuring that the copper busbar can be accurately conveyed to the flattening station, thereby preventing any impact on the flattening quality of the copper busbar.

[0016] 2. In this DC input copper busbar negative terminal flattening device, after the end of the copper busbar to be flattened is delivered to the flattening block, the hydraulic rod is activated, and its output end pushes the flattening block downward. During the downward movement of the flattening block, two first sliding rods slide on the mounting frame, serving to guide and stabilize the flattening block. Before the flattening block contacts the copper busbar, because the horizontal height of the clamping plate is lower than that of the flattening block, the clamping plate will first contact the copper busbar. At this time, the spring is compressed, and the rubber pad fits tightly against the copper busbar, firmly pressing the copper busbar onto the processing table to prevent the copper busbar from moving during the flattening process. Subsequently, the flattening block continues to move downward to flatten the copper busbar. The clamping plate and rubber pad in the flattening assembly can firmly press the copper busbar onto the processing table before flattening, preventing the copper busbar from moving or shaking during the flattening process, ensuring the stability of the flattening process, and thus improving the flattening quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides two technical solutions:

[0025] Figures 1-5 The first embodiment is shown: a DC input copper busbar negative electrode flattening device, including a base plate 1, a flattening component 2 is provided at the top of the base plate 1 for flattening the copper busbar, and a feeding component 3 is provided at the top of the base plate 1 for conveying the copper busbar.

[0026] The flattening assembly 2 includes a mounting frame 21. A hydraulic rod 22 is fixedly mounted on the top of the mounting frame 21. A flattening block 23 is fixedly mounted on the output end of the hydraulic rod 22. A mounting plate 25 is fixedly mounted on one side of the outer wall of the flattening block 23. Two second sliding rods 26 slide through the top of the mounting plate 25. A clamping plate 28 is fixedly mounted on the bottom end of the two second sliding rods 26.

[0027] The feeding assembly 3 includes a conveyor frame 31. A set of conveyor rollers 32 are rotatably mounted on the inner wall of the conveyor frame 31. A mounting shell 37 is fixedly mounted on the inner wall of the conveyor frame 31. Two sliders 39 are movably inserted into the inner wall of the mounting shell 37. A movable plate 38 is fixedly mounted on the top of each of the two sliders 39. A set of limiting rollers 36 is rotatably mounted on the top of each of the two movable plates 38. The two sets of limiting rollers 36 are staggered in the gap between the set of conveyor rollers 32. The copper busbar can be placed on the conveyor rollers 32 for conveying. The staggered arrangement of the two sets of limiting rollers 36 and the set of conveyor rollers 32 allows the limiting rollers 36 to collide with the conveyor rollers 32 when they come close to each other.

[0028] The mounting bracket 21 is fixedly installed on the top of the base plate 1. A processing table 29 is provided below the flattening block 23. The end of the copper busbar that needs to be flattened is placed on the processing table 29 so that it can be flattened by the flattening block 23 above. At the same time, the conveying roller 32 is set at an appropriate height so that the copper busbar can be conveyed to the processing table 29. The processing table 29 is fixedly installed on the top of the base plate 1. Two first sliding rods 24 slide through the top of the mounting bracket 21. The bottom ends of the two first sliding rods 24 are fixedly connected to the flattening block 23.

[0029] The mounting bracket 21 is fixedly installed on the top of the base plate 1. A processing table 29 is provided below the flattening block 23. The processing table 29 is fixedly installed on the top of the base plate 1. Two first sliding rods 24 slide through the top of the mounting bracket 21. The bottom ends of the two first sliding rods 24 are fixedly connected to the flattening block 23. The first sliding rods 24 can guide and stabilize the flattening block 23.

[0030] Figures 1-5 The second embodiment is shown, and its main difference from the first embodiment is:

[0031] Springs 27 are fitted on the outer walls of the two second sliding rods 26. One end of each spring 27 is fixedly connected to the mounting plate 25, and the other end is fixedly connected to the pressure plate 28. A rubber pad is fixedly installed at the bottom of the pressure plate 28. The horizontal height of the pressure plate 28 is lower than that of the flattening block 23. The rubber pad has a high coefficient of friction. When the pressure plate 28 is pressed down by the action of the springs 27, the rubber pad contacts the surface of the copper busbar, which can increase the friction between the copper busbar and the copper busbar, so that the copper busbar is more stably kept in its original position during the flattening process, preventing it from sliding due to the impact force of the flattening block 23 during flattening, thereby ensuring the accuracy and quality of the copper busbar flattening. After the flattening operation is completed, the hydraulic rod 22 drives the flattening block 23 to rise. At this time, the springs 27 will return to their original state, driving the pressure plate 28 back to the initial position, preparing for the next flattening operation, so that the device can achieve continuous and stable operation.

[0032] A sprocket and chain assembly 33 is provided on one side of the outer wall of the conveyor frame 31. One end of the outer wall of a set of conveyor rollers 32 extends through the outer wall of the conveyor frame 31. The set of conveyor rollers 32 are fixedly connected to each other through the sprocket and chain assembly 33. An L-shaped plate 34 is fixedly installed on one side of the outer wall of the conveyor frame 31. A first motor 35 is fixedly installed on the outer wall of the L-shaped plate 34. The output shaft of the first motor 35 passes through the outer wall of the L-shaped plate 34 and is fixedly connected to the sprocket and chain assembly 33. The sprocket and chain assembly 33 is existing technology and consists of multiple sprockets and chains. When the first motor 35 is turned on, it can drive multiple conveyor rollers 32 to rotate simultaneously, thereby enabling the conveying of copper busbars.

[0033] Two third slide rods 310 are fixedly installed on the inner wall of the mounting shell 37. The two sliders 39 are slidably connected to the two third slide rods 310, which can limit the sliders 39 so that the sliders 39 can only slide on the third slide rods 310. The conveyor frame 31 is fixedly installed on the top of the base plate 1.

[0034] A second motor 311 is fixedly installed at the bottom of the mounting housing 37. The output shaft of the second motor 311 passes through the inner wall of the mounting housing 37 and is fixedly installed on a rotating plate 312. Connecting plates 313 are rotatably installed at both ends of the outer wall of the rotating plate 312. One end of the outer wall of the two connecting plates 313 is rotatably connected to two moving plates 38 respectively. When the second motor 311 is turned on, it can drive the rotating plate 312 to rotate. The rotating plate 312 can drive the two moving plates 38 to move through the connecting plates 313.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, when feeding copper busbars, the first motor 35 is started first. The output shaft of the first motor 35 drives the sprocket and chain assembly 33 to rotate, which in turn drives a set of conveying rollers 32 to rotate synchronously. The copper busbar to be flattened is placed on the conveying rollers 32, and the rotation of the conveying rollers 32 realizes the conveying of the copper busbar. At the same time, the second motor 311 is started, and its output shaft drives the rotating plate 312 to rotate. The connecting plates 313 at both ends of the rotating plate 312 rotate accordingly. Since the connecting plate 313 is rotatably connected to the moving plate 38, and the slider 39 at the bottom of the moving plate 38 is slidably set in the mounting shell 37, the set of limiting rollers 36 on both sides can be brought closer to each other. The two sets of limiting rollers 36 contact the copper busbar to correct its deviation and prevent it from shifting during the conveying process, ensuring that the copper busbar can be accurately conveyed to the bottom of the flattening block 23. When the end of the copper busbar that needs to be flattened is conveyed to the flattening station, the hydraulic rod 22 is started, and its output end pushes the flattening block 23 downward. As the flattening block 23 moves downward, the two first sliding rods 24 slide on the mounting bracket 21, serving to guide and stabilize the flattening block 23. Before the flattening block 23 contacts the copper busbar, since the horizontal height of the clamping plate 28 is lower than that of the flattening block 23, the clamping plate 28 will contact the copper busbar first. At this time, the spring 27 is compressed, and the rubber pad fits tightly against the copper busbar, firmly pressing the copper busbar onto the processing table 29 to prevent the copper busbar from moving during the flattening process. Subsequently, the flattening block 23 continues to move downward to flatten the copper busbar. The clamping plate 28 and the rubber pad in the flattening assembly 2 can firmly press the copper busbar onto the processing table 29 before flattening, preventing the copper busbar from moving or shaking during the flattening process, ensuring the stability of the copper busbar flattening process, and thus improving the quality of copper busbar flattening.
