Description

Technical Field

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

[0002] Solar cell modules convert solar energy into electricity and are becoming increasingly common. During the production of solar cell modules, there's a process called busbar welding, which involves welding the busbars to the extended ribbons at both ends and the middle of the cell string.

[0003] Before busbar welding, a traction mechanism clamps one end of the busbar and pulls it horizontally onto the supporting surface of the strip preparation device. The strip preparation device then processes the busbar to obtain the busbar required for welding. To prevent interference between the traction mechanism and the strip preparation device during horizontal movement, the traction mechanism typically pulls the busbar at a certain height above the supporting surface of the strip preparation device. After the busbar is pulled to the specified position, the traction mechanism releases the busbar, allowing it to freely fall from a height onto the strip preparation device. However, the free fall of the busbar can easily cause it to shift position or even flip, affecting the subsequent smooth preparation of the busbar. Utility Model Content

[0017] In some embodiments, the opposite side walls of the first limiting portion and the second limiting portion are inclined downward to form a guiding slope; and / or, the distance between the first limiting portion and the second limiting portion is adjustable.

[0018] The guiding slopes formed on the opposite sides of the first and second stoppers guide the end of the strip as it falls, ensuring it is smoothly lowered onto the lifting surface. The spacing between the first and second stoppers is adjustable to accommodate strips of varying widths.

[0040] 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.

[0041] like Figures 1 to 3 As shown, the strip preparation device in the embodiment of the present application includes a carrying platform 1, a first lifting mechanism 2 and a second lifting mechanism 3, wherein:

[0042] The top of the carrying platform 1 has a carrying surface 13 for carrying the strip.

[0043] The first lifting mechanism 2 and the second lifting mechanism 3 are both arranged on the supporting platform 1, wherein the lifting end of the first lifting mechanism 2 is located on the first side (for example, the left side) of the supporting platform 1, and the lifting end of the second lifting mechanism 3 is located on the second side (for example, the right side) of the supporting platform 1.

[0044] The first lifting mechanism 2 and the second lifting mechanism 3 are configured to rise synchronously to support both ends of the strip sent above the carrying surface 13 .

[0045] The first lifting mechanism 2 and the second lifting mechanism 3 are further configured to descend synchronously to place the strips onto the carrying surface 13 .

[0046] It can be seen that the strip preparation device in the embodiment of the present application has the first lifting mechanism 2 and the third lifting mechanism 3 respectively provided on both sides of the carrier 1. Therefore, when the strip traction mechanism pulls the strip to be processed to the top of the carrier 1, the first lifting mechanism 2 and the third lifting mechanism 3 can rise toward the strip to receive the strip. Subsequently, the first lifting mechanism 2 and the third lifting mechanism 3 descend synchronously to lower the strip onto the carrier 1. In this way, the strip can be prevented from being offset and flipped. The strip preparation device in the embodiment of the present application is suitable for the preparation of busbars. Of course, it can also be used to prepare other types of strip products.

[0047] Optionally, the first lifting mechanism 2 and the second lifting mechanism 3 both include a lifting drive member 21 and a lifting block 22, wherein: the lifting drive member 21 is installed on the supporting platform 1, the lifting block 22 is transmission-connected to the driving end of the lifting drive member 21, and the lifting block 22 is located on the side of the supporting platform 1. The lifting drive member 21 is configured to drive the lifting block 22 to rise and fall. When the lifting drive member 21 drives the lifting block 22 to rise, the lifting block 22 extends upward from the supporting surface 13 to support the end of the strip sent to the top of the supporting surface 13. When the lifting drive member 21 drives the lifting block 22 to descend, the lifting block 22 retracts downward to below the supporting surface 13 to lower the strip onto the supporting surface 13.

[0048] The lifting drive member 21 can adopt various existing linear drive members that can drive the lifting block 22 to rise and fall, such as a pneumatic cylinder, an electric cylinder, etc.

[0049] Optionally, in order to improve the smoothness of the lifting and lowering of the lifting block 22, the strip preparation device in the embodiment of the present application also includes a slider and a slide rail, and the supporting platform 1 includes a supporting plate, a vertical plate and a base connected in sequence from top to bottom, and the top of the supporting plate has a supporting surface for supporting the strip, and the lifting block 22 is located on the side of the supporting plate; the lifting drive 21 is fixedly installed on the base, the slide rail is vertically installed on the vertical plate, the slider is slidably connected to the slide rail and is transmission-connected to the lifting drive 21, and the lifting block 22 is installed on the slider.

[0050] like Figure 1 As shown, optionally, the lifting block 22 is connected to the driving end of the lifting drive member 21 via the adapter plate 23. In this way, the lifting block 22 can be easily disassembled and assembled, and the connection strength between the lifting block 22 and the driving end of the lifting drive member 21 is ensured.

[0051] like Figures 3 and 4 As shown, optionally, a first limiting portion 24 and a second limiting portion 25 are provided in pairs on the top of the lifting block 22, and a horizontal lifting surface 26 is provided between the first limiting portion 24 and the second limiting portion 25. The lifting surface 26 is used to support the end of the strip, and the first limiting portion 24 and the second limiting portion 25 are used to limit the end of the strip in the width direction of the strip.

[0052] The first and second limiting portions 24, 25 limit the ends of the strip in the width direction of the strip, ensuring that the ends of the strip are positioned and retained on the lifting block 22, preventing the strip from slipping during the lifting process. The first and second limiting portions 24, 25 can, for example, be integrally formed on the top of the lifting block 22. Of course, the first and second limiting portions 24, 25 can also be limiting blocks installed on the top of the lifting block 22.

[0053] like Figure 4 As shown, optionally, the opposite side walls of the first limiting portion 24 and the second limiting portion 25 are inclined downward to form a guiding slope 27. When the strip pulling mechanism releases the strip, the guiding slope 27 can guide the end of the strip to fall, ensuring that the end of the strip is smoothly lowered to the lifting surface 26.

[0054] Optionally, the spacing between the first limiting portion 24 and the second limiting portion 25 is adjustable. For example, the first limiting portion 24 is fixed or integrally formed on the top of the lifting block 22, and the second limiting portion 25 is adjustably mounted on the top of the lifting block 22 via a waist hole. By adjusting the installation position of the second limiting portion 25, the spacing between the first limiting portion 24 and the second limiting portion 25 can be adjusted, thereby achieving compatibility with strips of different widths.

[0055] Optionally, the strip preparation device in the embodiment of the present application further includes a pressing mechanism 4 provided on the carrier 1, and the pressing mechanism 4 is used to press the strip against the carrier surface 13. The first lifting mechanism 2 and / or the second lifting mechanism 3 further include a bending member 28, which is transmission-connected to the driving end of the lifting drive member 21, and the bending member 28 is located between the lifting block 22 and the carrier 1. The lifting drive member 21 is further configured to drive the bending member 28 to rise, so that the bending member 28 extends upward from the carrier surface 13, so as to bend one end of the strip pressed against the carrier surface 13.

[0056] By setting the clamping mechanism 4 and the bending member 28, when the strip is lowered onto the carrying surface 13 of the carrying platform 1, the clamping mechanism 4 first presses the strip onto the carrying surface 13, and then the lifting drive 21 drives the bending member 28 to rise, thereby driving the bending member 28 to bend the end of the strip.

[0057] When both the first lifting mechanism 2 and the second lifting mechanism 3 are provided with bending members 28, the two bending members 28 can achieve synchronous bending of both ends of the strip under the synchronous drive of their respective lifting drive members 21. However, when only one of the first lifting mechanism 2 and the second lifting mechanism 3 is provided with a bending member 28, the strip preparation device of the present application only bends one end of the strip.

[0058] Optionally, the bending member 28 is a bending block with a curved bending surface formed on the top of the bending block 28. Alternatively, the bending member 28 is a roller. Using a bending block or roller with a curved bending surface as the bending member 28 can achieve smooth bending of the strip end and reduce wear on the strip.

[0059] like Figures 1 to 3 As shown, optionally, a clamping mechanism 4 is disposed near the bending member 28 and includes a clamping block 41 and a clamping driver 42, wherein the clamping driver 42 is disposed on the carrier platform 1. The clamping block 41 is rotatably connected to the carrier platform 1, and the clamping block 41 is hinged to a driving end of the clamping driver 42. The clamping driver 42 is configured to drive the clamping block 41 to rotate downward from the side of the carrier platform 1 onto the carrier surface 13 of the carrier platform 1, thereby clamping the strip on the carrier surface 13.

[0060] The clamping drive 42 can be, for example, a pneumatic cylinder. The lower end of the clamp 41 is hinged to the cylinder's telescopic rod, and the middle portion of the clamp 41 is pivotally connected to the support platform 1 via a rotating shaft. When the cylinder's telescopic rod is extended, the upper end of the clamp 41 rotates toward the support surface 13 of the support platform 1, thereby compressing the strip on the support surface 13. When the cylinder's telescopic rod is retracted, the upper end of the clamp 41 rotates away from the support surface 13 of the support platform 1, releasing the strip.

[0061] like Figure 1 As shown, optionally, a pair of first and second positioning pins 5 and 6 are provided on the support surface 13, with a limiting gap for accommodating the strip formed between the first and second positioning pins 5 and 6. The first and second positioning pins 5 and 6 cooperate to limit the strip from both sides to prevent the strip from sliding off the support platform 1.

[0062] like Figures 1 to 2 As shown, optionally, the supporting platform 1 includes a first supporting platform 11 and a second supporting platform 12 arranged side by side, wherein: the first lifting mechanism 2 is arranged on the first supporting platform 11, and the lifting end of the first lifting mechanism 2 is located on the first side of the first supporting platform 1; the second lifting mechanism 3 is arranged on the second supporting platform 12, and the lifting end of the second lifting mechanism 3 is located on the second side of the second supporting platform 12.

[0063] The carrying platform 1 is configured as a split structure consisting of a first carrying platform 11 and a second carrying platform 12 , which facilitates the installation and maintenance of the strip preparation device while ensuring that both ends of the strip are lifted and bent.
