Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production equipment, and specifically to a busbar preparation device. Background Art

[0002] Solar cell modules convert solar energy into electricity and are becoming increasingly popular. During the production of solar cell modules, there's a process called busbar welding, which involves welding the busbars to the extended ribbons of the battery string. To facilitate subsequent installation of the junction box, the busbars welded to the extended ribbons in the middle of the battery string are bent with bent ends. These bent ends are inserted into the junction box and welded together.

[0003] Before busbar welding, a busbar preparation device bends the ends of the busbars to obtain busbars with bent ends. Existing busbar preparation devices include a supporting platform, a bending rod, and a bending rod driver. The supporting platform is used to support the busbar to be bent. The bending rod is arranged on the side of the supporting platform and is in transmission connection with the bending rod driver. The bending rod driver is used to drive the bending rod up and down to drive the bending rod to bend the busbar so that it extends out of the supporting platform.

[0004] A problem with existing busbar preparation devices is that the bending rods are prone to shaking during the rising process, resulting in poor bending effect on the busbars. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a busbar preparation device, which adopts the following technical solutions:

[0006] A busbar preparation device includes a base, a first lifting drive unit, a bearing platform, a guide rod, a slider, a guide seat, a second lifting drive unit and a bending rod, wherein:

[0007] The first lifting drive unit is installed on the base;

[0008] The carrying platform is arranged on the movable component of the first lifting drive unit, and the carrying platform has a carrying surface for carrying the bus bar. The first lifting drive unit is used to drive the carrying platform to move up and down;

[0009] The upper end of the guide rod is fixedly connected to the bearing platform, and the guide seat is arranged on the base. The guide seat is provided with a guide hole matching the guide rod. The guide rod is downwardly inserted into the guide hole, and the guide hole guides the guide rod to be lifted and lowered;

[0010] The second lifting drive unit is arranged on the bearing platform, the slider is slidably connected to the guide rod and is connected to the movable component of the second lifting drive unit, and the second lifting drive unit is used to drive the slider to slide up and down along the guide rod;

[0011] The lower end of the bending rod is connected to the slider, and the upper end of the bending rod is located on the side of the supporting platform and close to the supporting platform. When the second lifting drive unit drives the slider to slide upward, the upper end of the bending rod extends upward from the supporting surface to bend the end of the bus bar located on the supporting surface.

[0012] When using the busbar preparation device of the present application to prepare a bent busbar, the first lifting drive unit first drives the carrier platform to a low position. When the external busbar pulling device pulls the busbar to the top of the carrier platform, the first lifting drive unit drives the carrier platform to a high position to receive the busbar. Subsequently, the second lifting drive unit drives the slider to slide upward to drive the bending rod to bend the end of the busbar. Since the upper end of the guide rod is fixedly connected to the carrier platform and the guide rod is located in the guide hole of the guide seat, when the first lifting drive unit drives the carrier platform to rise and fall, the guide rod guides the lifting of the carrier platform, thereby improving the lifting stability of the carrier platform; when the second lifting drive unit drives the bending rod to rise via the slider, the guide rod guides the lifting of the bending rod to prevent the bending rod from shaking during the rising process, thereby ensuring the bending effect of the bending rod on the busbar.

[0013] In some embodiments, the supporting platform includes a mounting seat and a supporting plate, wherein: the mounting seat is arranged on the movable part of the first lifting drive unit, and the second lifting drive unit is arranged at the bottom of the mounting seat; the supporting plate is installed on the top of the mounting seat, and the supporting plate has a supporting surface.

[0014] The bearing platform is configured as a split structure consisting of a mounting seat and a bearing plate, which facilitates the processing, forming, disassembly, and maintenance of the bearing platform. The mounting seat can also provide stable support for the bearing plate.

[0015] In some embodiments, a downwardly opening mounting groove is provided at the bottom of the mounting seat, and the second lifting drive unit is provided in the mounting groove.

[0016] The second lifting drive unit is arranged in the installation groove, which increases the stability of the second lifting drive unit and ultimately improves the driving smoothness of the bending rod by the second lifting drive unit.

[0017] In some embodiments, the lower end of the bending rod is connected to the slider via an adapter plate.

[0018] The lower end of the bending rod is connected to the slider via the adapter plate, which facilitates the disassembly and assembly of the bending rod and increases the connection strength between the bending rod and the slider.

[0019] In some embodiments, the busbar preparation apparatus includes two guide rods arranged side by side.

[0020] The two guide rods arranged side by side cooperate to guide the lifting of the slider, which can further improve the lifting stability of the slider and the bending rod.

[0021] In some embodiments, the busbar preparation apparatus further includes a pressing mechanism configured to press the busbar onto the supporting surface.

[0022] Before the bending rod bends the end of the busbar upward, the pressing mechanism first presses the busbar against the bearing surface, thereby ensuring that the end of the busbar can be bent smoothly.

[0023] In some embodiments, the clamping mechanism includes a clamping block and a clamping drive, wherein: the clamping drive is arranged on a base or a supporting platform; the clamping block is rotatably connected to the supporting platform, the clamping block is hinged to the driving end of the clamping drive, and the clamping drive is configured to drive the clamping block to rotate down from the side of the supporting platform to the supporting surface of the supporting platform, thereby clamping the bus bar on the supporting surface.

[0024] A compacting mechanism with a simple structure is provided, which drives a compacting block to rotate toward or away from a bearing surface of a bearing platform through a compacting driving member, so as to implement rapid compaction or release of a busbar located on the bearing surface.

[0025] In some embodiments, the pressing block is close to the bending rod, pressing the first end of the busbar, and the first end of the busbar extends outward from the bearing surface. When the upper end of the bending rod extends upward from the bearing surface, the first end of the busbar is bent.

[0026] Ensure that when the upper end of the bending rod extends out of the bearing surface, the end of the convection strip can be bent.

[0027] In some embodiments, a first positioning pin and a second positioning pin are provided in pairs on the bearing surface, and a positioning gap for defining the bus bar is formed between the first positioning pin and the second positioning pin.

[0028] The first positioning pin and the second positioning pin cooperate to limit the busbar from both sides to prevent the busbar from sliding off the supporting platform.

[0029] In some embodiments, a sensing element for sensing the bus bar is disposed on the supporting surface.

[0030] By installing a sensor on the support surface, the busbar's position is detected. Once the busbar is placed on the support platform, the second lifting drive unit immediately drives the bending rod to bend the busbar, reducing delays and improving production efficiency.

DETAILED DESCRIPTION

[0051] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] like Figures 1 to 4 As shown, the busbar preparation device 10 in the embodiment of the present application includes a base 1, a first lifting drive unit 2, a supporting platform 3, a guide rod 4, a slider 5, a guide seat 6, a second lifting drive unit 7 and a bending rod 8, wherein:

[0053] The first lifting drive unit 2 is installed on the base 1 .

[0054] The carrying platform 3 is arranged on the movable component of the first lifting drive unit 2. The carrying platform 3 has a carrying surface for carrying the busbar. The first lifting drive unit 2 is used to drive the carrying platform 3 to move up and down.

[0055] The upper end of the guide rod 4 is fixedly connected to the supporting platform 3, and the guide seat 6 is arranged on the base 1. The guide seat 6 is provided with a guide hole matching the guide rod. The guide rod 4 is inserted downward into the guide hole, and the guide hole guides the guide rod 4 to be lifted and lowered.

[0056] The second lifting drive unit 7 is arranged on the supporting platform 3 , the slider 5 is slidably connected to the guide rod 4 and is connected to the movable part of the second lifting drive unit 7 , and the second lifting drive unit 7 is used to drive the slider 5 to slide up and down along the guide rod 4 .

[0057] The lower end of the bending rod 8 is connected to the slider 5, and the upper end of the bending rod 8 is located on the side of the supporting platform 3 and close to the supporting platform 3. When the second lifting drive unit 7 drives the slider 5 to slide upward, the upper end of the bending rod 8 extends upward from the supporting surface to bend the end of the bus bar located on the supporting surface.

[0058] The optional working process of the busbar preparation device in the embodiment of the present application is as follows:

[0059] When a bent busbar needs to be prepared, the first lifting drive unit 2 first drives the supporting platform 3 to a low position to avoid the busbar pulling device, and the upper end of the bending rod 8 is lower than the supporting surface of the supporting platform 3.

[0060] When the busbar pulling device pulls the busbar above the support platform 3, the first lifting drive unit 2 drives the support platform 3 to a high position to receive the busbar released by the busbar pulling device. The end of the busbar to be bent extends outward to above the bending rod 8.

[0061] Subsequently, the second lifting drive unit 7 drives the slider 5 to slide upward, so as to drive the upper end of the bending rod 8 to extend upward from the bearing surface of the bearing platform 3 to bend the end of the busbar.

[0062] Because the upper end of the guide rod 4 is fixedly connected to the carrier platform 3 and the guide rod 4 is located in the guide hole of the guide seat 6, when the first lifting drive unit 2 drives the carrier platform 3 to rise and fall, the guide rod 4 guides the lifting of the carrier platform 3, thereby improving the lifting stability of the carrier platform 3. In addition, when the second lifting drive unit 7 drives the bending rod 8 to rise via the slider 5, the guide rod 4 guides the lifting of the bending rod 8, preventing the bending rod 8 from shaking during the rising process and ensuring the bending rod 8's bending effect on the busbar.

[0063] The first lifting drive unit 2 and the second lifting unit 7 can both adopt various existing linear drive components, such as a pneumatic cylinder, an electric cylinder, etc.

[0064] Optionally, the support platform 3 includes a mounting base 31 and a supporting plate 32, wherein the mounting base 31 is disposed on the movable component of the first lifting drive unit 2, and the second lifting drive unit 7 is disposed at the bottom of the mounting base 31. The supporting plate 32 is mounted on top of the mounting base 31 and has a supporting surface. Configuring the support platform 3 as a split structure consisting of the mounting base 31 and the supporting plate 32 facilitates processing, assembly, disassembly, and maintenance of the support platform 3. The mounting base 31 also provides stable support for the supporting plate 32. Of course, the support platform 3 can also be configured as a one-piece structure.

[0065] like Figure 1 As shown, optionally, a downwardly opening mounting groove is provided at the bottom of the mounting base 31, and the second lifting drive unit 7 is disposed in the mounting groove. Placing the second lifting drive unit 7 in the mounting groove increases the installation stability of the second lifting drive unit 7, and ultimately improves the smoothness of the second lifting drive unit 7 driving the bending rod 8.

[0066] like Figure 1 As shown, optionally, the lower end of the bending rod 8 is connected to the slider via an adapter plate 9. The lower end of the bending rod 8 is connected to the slider 5 via the adapter plate 9, which facilitates the disassembly and assembly of the bending rod 8 and ensures the connection strength of the bending rod 8 and the slider 5.

[0067] like Figure 1 and Figure 4 As shown, the busbar preparation device in the embodiment of the present application optionally includes two guide rods 4 arranged side by side. The two guide rods 4 arranged side by side cooperate to guide the lifting of the slider 5, which can further improve the lifting stability of the slider 5 and the bending rod 8.

[0068] like Figure 1 and Figure 3 As shown, the busbar preparation device in the embodiment of the present application optionally further includes a pressing mechanism 10. Before the bending rod 8 bends the end of the busbar upward, the pressing mechanism 10 presses the busbar against the supporting surface of the supporting platform 3, thereby ensuring that the end of the busbar can be bent by the bending rod 8.

[0069] like Figure 2 As shown, optionally, the pressing mechanism 10 includes a pressing block 101 and a pressing driver 102, wherein the pressing driver 102 is disposed on the base 1 or the carrier 3. The pressing block 101 is rotatably connected to the carrier 3, and the pressing block 101 is hinged to the driving end of the pressing driver 102. The pressing driver 102 is configured to drive the pressing block 101 to rotate downward from the side of the carrier 3 to the carrier surface of the carrier 3, thereby pressing the busbar on the carrier surface.

[0070] The clamping drive 102 can be, for example, a pneumatic cylinder. The lower end of the clamp 101 is hinged to the cylinder's telescopic rod, and the middle portion of the clamp 101 is pivoted to the support platform 3 via a rotating shaft. When the cylinder's telescopic rod is extended, the upper end of the clamp 101 rotates toward the support surface of the support platform 3, thereby compressing the busbar on the support surface. When the cylinder's telescopic rod is retracted, the upper end of the clamp 101 rotates away from the support surface of the support platform 3, releasing the busbar.

[0071] Optionally, the pressing block 101 is positioned close to the bending rod 8, pressing the first end of the busbar tightly. The first end of the busbar extends outward from the support surface, and the upper end of the bending rod 8 extends upward from the support surface, thereby bending the first end of the busbar. Since the pressing block 101 is positioned close to the first end of the busbar to be bent and presses the busbar tightly, the bending rod 8 can smoothly bend the first end of the busbar when it is raised.

[0072] like Figures 1 to 3 As shown, optionally, a first locating pin 12 and a second locating pin 13 are provided in pairs on the supporting surface of the support platform 3. A positioning gap is formed between the first locating pin 12 and the second locating pin 13 to limit the positioning of the busbar. After the busbar to be bent is placed on the support platform 3, the first locating pin 12 and the second locating pin 13 cooperate to limit the position of the busbar from both sides, preventing the busbar from sliding off the support platform 3.

[0073] like Figure 1 As shown, the supporting surface of the platform 3 is optionally provided with a sensor 11 for sensing the busbar. Once the busbar is placed on the platform 3, the sensor 11 generates a position sensing signal. The second lifting drive 7 then drives the bending rod 8 to bend the busbar, thereby reducing delays and improving production efficiency.

[0074] As those skilled in the art are aware, during the production of solar cell modules, for certain models of solar cell modules, it is necessary to weld an L-shaped busbar with one end bent and a U-shaped busbar with both ends bent to the extended welding ribbon in the middle of the cell string. Optionally, a busbar preparation device composed of several busbar preparation devices according to the embodiments of the present application can be used to prepare L-shaped and U-shaped busbars.

[0075] For example, Figure 5 The busbar preparation apparatus shown includes a first busbar preparation device 100, a second busbar preparation device 200, a third busbar preparation device 300, a fourth busbar preparation device 400, a fifth busbar preparation device 500, and a sixth busbar preparation device 600 arranged in sequence along a first horizontal direction (indicated by the arrow in the figure), wherein:

[0076] The first busbar preparation device 100 and the second busbar preparation device 200 can cooperate to prepare the L-shaped busbar 700. Specifically, the busbar pulling mechanism pulls a busbar of a first length onto the supporting platform 3 of the first and second busbar preparation devices 100 and 200, with the second end (e.g., the right end) of the first busbar extending outward from the supporting platform 3 of the second busbar preparation device 200. The second end of the first busbar is then bent upward by the bending rod 8 of the second busbar preparation device 200, thereby forming the L-shaped busbar 700.

[0077] The third busbar preparation device 300, the fourth busbar preparation device 400, the fifth busbar preparation device 500, and the sixth busbar preparation device 600 can cooperate to prepare the U-shaped busbar 800. Specifically, the busbar pulling mechanism pulls the busbar of the second length onto the supporting platform 3 of the third busbar preparation device 300, the fourth busbar preparation device 400, the fifth busbar preparation device 500, and the sixth busbar preparation device 600, so that the first end (e.g., the left end) of the second busbar extends outward from the supporting platform 3 of the third busbar preparation device 300, and the second end (e.g., the right end) of the second busbar extends outward from the supporting platform 3 of the sixth busbar preparation device 600. The first end of the second busbar is bent upward by the bending rod 8 of the third busbar preparation device 300, and the second end of the second busbar is bent upward by the bending rod 8 of the sixth busbar preparation device 600, thereby obtaining the U-shaped busbar 800.

[0078] In actual use, the busbar preparation devices in the embodiments of the present application can be used in combination in any number or can be used individually.

[0079] The present application has been described above in sufficient detail with certain specificity. Those skilled in the art will understand that the descriptions in the examples are merely illustrative, and that all modifications made without departing from the true spirit and scope of the present application are intended to be within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the description in the examples.
