Technical Field
[0001] This utility model belongs to the field of copper busbar production technology, specifically relating to a copper flexible connector diffusion welding post-shaping device. Background Technology
[0002] Copper flexible connectors are mostly used in the electrical industry, and diffusion soldering is an essential part of the manufacturing process. The soldering process involves stacking and overlapping multiple layers of copper foil to achieve the required thickness, and then using polymer diffusion soldering to form the multiple layers of copper foil under pressure and heat.
[0003] In existing technologies, during the pressure and heating process of copper foil forming, the pressure causes the copper foil at the welding point to be relatively flat. However, the high temperature causes unevenness at the intersection of the flat copper foil at the welding point and the unpressed copper foil. Generally, the product's appearance fails to meet technical requirements, and in severe cases, it can lead to a reduction in the product's electrical performance. Current solutions involve manual tapping with a rubber mallet, which imposes extremely high labor intensity on production workers and results in low production efficiency. Utility Model Content
[0004] In view of this, the present invention provides a shaping device for copper flexible connector diffusion soldering, the purpose of which is to quickly roll the unpressed part of the copper foil, shorten the shaping time, reduce labor costs, and improve the appearance quality of the product.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A shaping device for copper flexible connector diffusion soldering includes a shaping chamber. The shaping chamber contains an active roller and a driven roller, both horizontally positioned within the chamber. The driven roller is positioned above the active roller. Both ends of the active roller are externally connected to drive components for rotating it. Both ends of the driven roller are equipped with lifting assemblies for adjusting the gap between the driven and active rollers. Each lifting assembly includes a lifting groove, a lead screw, and moving blocks. Two lifting grooves are respectively formed on the outer walls of the left and right sides of the shaping chamber, extending from the top to the bottom. Two moving blocks are slidably connected to the interiors of the two lifting grooves. Both ends of the driven roller are inserted into the two moving blocks. The lead screw passes through the moving blocks and is connected between the top and bottom of the shaping chamber.
[0007] As a preferred technical solution, the top of the shaping chamber is provided with a rotating component for rotating the lead screw. The rotating component includes a rotating shaft, a driving part, and a transmission shaft. The top end of the transmission shaft is provided with a first spiral bevel gear, and the bottom end of the transmission shaft passes through the top of the shaping chamber and connects to the top of the lead screw. The driving part is located at the top of the shaping chamber. One end of the rotating shaft is connected to the driving part, and the other end of the rotating shaft is provided with a second spiral bevel gear, wherein the second spiral bevel gear meshes with the first spiral bevel gear.
[0008] Furthermore, scales are provided on the outer walls of both sides of the shaping chamber, wherein the scales are located outside the opening of the lifting groove and extend along the length of the lifting groove.
[0009] Furthermore, it also includes a feed inlet and a discharge outlet on the shaping chamber. The feed inlet is located on the front of the shaping chamber, and a feed plate is provided inside the feed inlet. One end of the feed plate faces the drive roller, and the other end extends to the outside of the shaping chamber. The discharge outlet is located on the back of the shaping chamber, and a discharge plate is provided inside the discharge outlet. The discharge plate and the feed plate are distributed relative to each other with the center of the drive roller as a reference.
[0010] Furthermore, the front of the shaping chamber is also provided with a baffle, and the baffle is located above the feed plate.
[0011] Furthermore, the bottom of the shaping chamber is provided with a water receiving box, wherein the opening of the water receiving box faces downwards from the active roller.
[0012] Furthermore, the inner wall of the water receiving box is provided with a removable sponge pad.
[0013] Furthermore, an installation groove is provided on the inner wall of the water receiving box, wherein the sponge pad is adapted to the installation groove.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] 1. By using a drive roller and a driven roller, the hot-pressed copper foil can be sandwiched between them. Then, the drive roller begins to rotate. Through the interaction of the drive and driven rollers and the effect of friction, the copper foil is moved forward at a uniform speed. During this process, the soldered areas and surrounding regions of the copper foil are subjected to uniform pressure, effectively flattening the foil.
[0016] 2. By setting up the lifting component, the gap between the driven roller and the driving roller can be adjusted, thereby adapting to the processing requirements of copper foil of different thicknesses, further improving the practicality and versatility of the shaping device.

[0022] 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.
[0023] In existing technologies, during the pressing and heating forming process, the welded areas of the copper foil become relatively flat due to pressure. However, under high temperatures, unevenness easily occurs at the interface between the flat copper foil at the welded areas and the unpressed areas. This typically results in the product's appearance failing to meet technical specifications, and more seriously, it can degrade the product's electrical performance. Currently, this problem is usually solved manually, using a rubber mallet to tap the foil. This not only increases the labor intensity of production workers but also results in low production efficiency.
[0024] Example 1
[0025] Therefore, in order to solve the above problems and achieve the function of quickly flattening copper foil and reducing labor costs, this utility model discloses a copper flexible connector diffusion soldering post-shaping device, see reference. Figure 1 and Figure 2The device includes a shaping chamber 1. Specifically, the shaping chamber 1 is equipped with an active roller 8 and a driven roller 7. Both the active roller 8 and the driven roller 7 are horizontally positioned inside the shaping chamber 1. The driven roller 7 is positioned above the active roller 8. Both ends of the active roller 8 are externally connected to drive components for rotating the active roller 8. Both ends of the driven roller 7 are equipped with lifting components for adjusting the gap between the driven roller 7 and the active roller 8. The lifting components include lifting grooves, lead screws 6, and moving blocks 11. The two lifting grooves are respectively opened on the outer walls of the left and right sides of the shaping chamber 1, and the lifting grooves extend from the top of the shaping chamber 1 to the bottom of the shaping chamber 1. The two moving blocks 11 are slidably connected to the interior of the two lifting grooves. Both ends of the driven roller 7 are respectively inserted into the two moving blocks 11. The lead screw 6 passes through the moving blocks 11 and is connected between the top and bottom of the shaping chamber 1.
[0026] In this embodiment, the user places the hot-pressed copper foil on the active roller 8, and then uses a lifting assembly to lower the driven roller 7 to the top of the copper foil, so that the copper foil can be sandwiched between the active roller 8 and the driven roller 7. Next, the drive unit is activated, causing the active roller 8 to rotate. After the active roller 8 starts rotating, through the interaction between the active roller 8 and the driven roller 7 and the action of friction, the copper foil is driven forward at a uniform speed. During this process, the welding area and surrounding area of the copper foil are subjected to uniform pressure, and the copper foil is effectively flattened. Since the entire process is completed automatically by a mechanical device, there is no need for tedious manual hammering, reducing the labor intensity of production workers and significantly improving production efficiency. Moreover, the gap between the driven roller 7 and the active roller 8 can be adjusted by the lifting assembly, thereby adapting to the processing needs of copper foil of different thicknesses, further enhancing the practicality and versatility of the shaping device.
[0027] In a specific implementation, when the lifting assembly is in use, the user can rotate the lead screw 6 so that the moving block 11 can move the driven roller 7 up and down along the length of the lifting groove, thereby adjusting the distance between the driven roller 7 and the driving roller 8 to adapt to copper foil of different thicknesses.
[0028] It should be noted that the driving component can be a motor, which drives the end of the active roller 8 to start rotating.
[0029] In this embodiment, both ends of the driven roller 7 can rotate within the moving block 11, so that the driven roller 7 can also rotate while following the moving block 11 up and down, ensuring its coordinated work with the active roller 8, which helps to ensure the smooth transmission and uniform pressure of the copper foil during the shaping process.
[0030] Example 2
[0031] Based on Example 1, in order to ensure that the lead screw 6 can rotate smoothly, refer to... Figure 2 The present invention also includes a rotating component for rotating the lead screw. Specifically, the rotating component includes a rotating shaft 4, a driving part and a transmission shaft 5. The top end of the transmission shaft 5 is provided with a first spiral bevel gear, and the bottom end of the transmission shaft 5 passes through the top of the shaping chamber 1 and is connected to the top of the lead screw 6. The driving part is located at the top of the shaping chamber 1. One end of the rotating shaft 4 is connected to the driving part, and the other end of the rotating shaft 4 is provided with a second spiral bevel gear, wherein the second spiral bevel gear meshes with the first spiral bevel gear.
[0032] In this embodiment, the user operates the drive unit to drive the rotating shaft 4 to rotate, and the second spiral bevel gear on the rotating shaft 4 rotates accordingly. Since the second spiral bevel gear meshes with the first spiral bevel gear at the top of the transmission shaft 5, the rotational power is transmitted to the transmission shaft 5, thereby realizing the rotation of the lead screw 6, driving the moving block 11 to rise and fall, and finally adjusting the gap between the driven roller 7 and the driving roller 8.
[0033] The drive unit can be a motor or other mechanism with a rotatable shaft 4, which is existing technology and will not be described in detail below.
[0034] Furthermore, when adjusting the height of the driven roller 7 using the lead screw 6, in order to improve the accuracy of the adjustment, scales 10 are provided on the outer walls of both sides of the forming chamber 1. The scales 10 are located outside the opening of the lifting groove and extend along the length of the lifting groove. This arrangement allows the user to intuitively read the lifting height of the moving block 11 according to the scales 10 when adjusting the gap between the driven roller 7 and the driving roller 8, thereby controlling the gap size and ensuring that the forming operation for copper foil of different thicknesses is more precise and reliable, thus improving the forming quality and consistency of the product.
[0035] Example 3
[0036] Based on Example 1, to facilitate the loading and unloading of longer copper foils, please refer to... Figure 1 and Figure 3 The present invention also includes a feed inlet and a discharge outlet provided on the shaping chamber 1. Specifically, the feed inlet is located on the front side of the shaping chamber 1, and a feed plate 2 is provided inside the feed inlet. One end of the feed plate 2 faces the active roller 8, and the other end extends to the outside of the shaping chamber 1. The discharge outlet is located on the back side of the shaping chamber 1, and a discharge plate is provided inside the discharge outlet. The discharge plate and the feed plate 2 are distributed relative to each other with the center of the central axis of the active roller 8 as a reference.
[0037] In this embodiment, the above structure allows the shaping chamber 1 to accommodate some longer copper foils.
[0038] In a specific implementation, the feed plate 2 and the discharge plate can support the copper foil. When feeding, the user can connect one end of the copper foil between the active roller 8 and the driven roller 7, and place the other end of the copper foil on the feed plate 2. Then, the active roller 8 is turned on, so that the active roller 8 rotates and pulls the other end of the copper foil until all parts of the copper foil are crushed by the roller.
[0039] In addition, to prevent users from accidentally putting their hands into the feed inlet when loading materials, the front of the shaping chamber 1 is also provided with a baffle 3, which is located above the feed plate 2, so as to block the top of the feed inlet and prevent the risk of users putting their hands into the feed inlet.
[0040] Example 4
[0041] Based on Example 1, since the copper foil needs to be cooled with cooling water during the pressurization and heating process, some residual cooling water will flow out when the hot-pressed copper foil is rolled. To prevent the outflowing water from causing corrosion to the inside of the forming chamber 1, please refer to... Figure 2 The present invention also includes a water receiving box 9 for receiving cooling water. Specifically, the bottom of the shaping chamber 1 is provided with a water receiving box 9, wherein the opening of the water receiving box 9 faces downwards from the active roller 8.
[0042] In this embodiment, when the copper foil is crushed by the active roller 8 and the driven roller 7 and cooling water flows out, as the active roller 8 rotates, the cooling water will drip into the water receiving box 9 under the action of gravity. At the same time, since the inner wall of the water receiving box 9 is provided with a removable sponge pad, the sponge pad can effectively absorb the dripping water, prevent the water from shaking in the water receiving box 9 and causing noise or overflow, and the removable structure also makes it easy for the user to replace the sponge pad.
[0043] In one embodiment, to facilitate the disassembly and installation of the sponge pad, an installation groove is provided on the inner wall of the water receiving box 9, wherein the sponge pad is adapted to the installation groove. This arrangement allows the sponge pad to be simply inserted into the installation groove when installing it, and to be simply pulled out of the installation groove when disassembling it.
[0044] In summary, based on Examples 1 to 4, the working steps of this copper flexible connector diffusion soldering post-shaping device are as follows:
[0045] First, based on the thickness of the copper foil to be shaped, observe the scale 10 on the outer walls of the left and right sides of the shaping chamber 1. By rotating the rotating shaft 4 (the drive unit drives the rotating shaft 4 to rotate, and the second spiral bevel gear on the rotating shaft 4 meshes with the first spiral bevel gear at the top of the transmission shaft 5, thereby driving the transmission shaft 5 to rotate, which in turn causes the lead screw 6 to rotate), adjust the gap between the driven roller 7 and the driving roller 8 to a suitable size. Then, feed the hot-pressed copper foil into the shaping chamber 1 through the feed plate 2 of the feed inlet and place it on the driving roller 8 (make sure that the baffle 3 on the front of the shaping chamber 1 is in the normal position to prevent hands from accidentally entering the feed inlet). At the same time, connect one end of the copper foil between the driving roller 8 and the driven roller 7, and place the other end of the copper foil on the feed plate 2. Next, the drive unit (such as a motor) is activated, causing the active roller 8 to rotate. The rotating active roller 8 pulls the other end of the copper foil, moving it forward at a constant speed. Under the combined action of the active roller 8 and the driven roller 7, the welding area and surrounding region of the copper foil are flattened and shaped. During the shaping process, carefully observe the water level in the water receiving box 9. If the sponge pad becomes saturated with water, remove and replace it promptly. After shaping, the copper foil is smoothly output from the discharge plate at the discharge port, completing the entire shaping process.
