Description

Technical Field

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

[0002] During the production of photovoltaic modules, one of the processes is to weld busbars to the ends of the arranged battery strings. Before welding the busbars, a busbar preparation device is required to cut the rolled busbars into busbar segments of a certain length. For busbars with different positions and process requirements on the battery string, there will be different requirements for the cutting shape of the busbar ends. Some busbars require both ends to be cut into right angles, some busbars require both ends to be cut into rounded corners, and some busbars require one end to be cut into a right angle and the other end to be rounded.

[0003] The existing busbar preparation device generally includes a traction mechanism, a cutting mechanism and a pressing mechanism. The busbar passes through the pressing mechanism and the cutting mechanism in sequence under the traction of the traction mechanism. When the busbar of a predetermined length passes through the cutting mechanism, the pressing mechanism presses the busbar, the traction mechanism keeps the busbar taut, and the cutting mechanism then cuts the busbar to obtain a busbar segment. The existing busbar preparation device has the following technical problems: when the cutting mechanism cuts the busbar, the busbar between the traction mechanism and the cutting mechanism is relatively long, and is easily deformed by the release of the cutting stress, and the clamping end of the busbar is easily arched upward.

[0040] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] like Figure 1 As shown, the busbar preparation device in the embodiment of the present application includes a traction mechanism 1, a feeding mechanism (not shown in the figure), a pressing mechanism 2, a cutting mechanism 3 and a clamping mechanism 4, wherein:

[0042] The traction mechanism 1 is used to traction the busbar supplied by the feeding mechanism, so that the busbar is moved along a first horizontal direction (such as Figure 1 The X-axis direction in the figure) passes through the clamping mechanism 2, the cutting mechanism 3 and the clamping mechanism 4 in sequence.

[0043] The pressing mechanism 2 is used to press the busbar from the front side of the cutting mechanism 3, the clamping mechanism 4 is used to clamp the busbar from the rear side of the cutting mechanism 3, and the cutting mechanism 3 is used to cut the busbar to obtain a busbar with a predetermined length.

[0044] The working process of the busbar preparation device of the embodiment of the present application is as follows:

[0045] First, the pulling mechanism 1 clamps the free end of the busbar released from the feeding mechanism from the cutting mechanism 3 and pulls the busbar along the first horizontal direction.

[0046] When the busbar of a predetermined length passes through the cutting mechanism 3 , the traction mechanism 1 stops traction, the pressing mechanism 2 presses the busbar from the front side of the cutting mechanism 3 , and the clamping mechanism 4 clamps the busbar from the back side of the cutting mechanism 3 .

[0047] Subsequently, the cutting mechanism 3 cuts the busbar to obtain a busbar of a predetermined length. After the cutting is completed, the clamping mechanism 4 releases the busbar, and the pressing mechanism 2 keeps pressing the busbar, ensuring that the new free end of the busbar released from the feeding mechanism remains in the cutting mechanism 3, which is convenient for the traction mechanism 1 to clamp the busbar next time.

[0048] As known to those skilled in the art, the cutting mechanism 3 can be any other mechanism capable of achieving the purpose of cutting, such as a cutter, scissors, a punching die, etc. The following will be described using an embodiment in which the cutting mechanism 3 is a punching die.

[0049] In the busbar preparation device of the embodiment of the present application, a clamping mechanism 4 is provided between the cutting mechanism 3 and the pulling mechanism 1, and the clamping mechanism 4 clamps the busbar when punching the busbar pressed by the pressing mechanism 2. In this way, the stress generated by the cutting mechanism 3 during punching is buffered, thereby preventing the busbar between the pulling mechanism 1 and the cutting mechanism 3 from being deformed due to the release of the punching stress.

[0050] like Figure 3 As shown, optionally, the clamping mechanism 4 includes a first translation module 41, a first mounting plate 42 and a first clamping assembly 43, wherein the first mounting plate 42 is connected to the driving end of the first translation module 41, and the first clamping assembly 43 is arranged on the first mounting plate 42. The first translation module 41 is used to drive the first mounting plate 42 to translate toward or away from the bus bar, so as to drive the first clamping assembly 43 to approach the bus bar or avoid the traction mechanism 1.

[0051] In the initial state, the first clamping assembly 43 is in an evasive position to avoid the traction mechanism 1. After the busbar is pulled into place by the traction mechanism 1, the first translation module 41 drives the first clamping assembly 43 to translate toward the busbar to clamp the busbar.

[0052] The first translation module 41 can adopt various existing linear drive modules that can drive the first mounting plate 42 to translate toward or away from the bus bar, such as a screw drive module composed of a motor, a screw, and a screw nut, or a cylinder drive module composed of a cylinder and a slide rail pair.

[0053] Optionally, the first clamping assembly 43 includes a first fixed clamping jaw 431, a first movable clamping jaw 432 and a first clamping driver 433, wherein the first clamping driver 433 is disposed on the first mounting plate 42. The first fixed clamping jaw 431 is fixedly connected to the first mounting plate 42, and the first movable clamping jaw 432 is hinged on the first mounting plate 42 and connected to the driving end of the first clamping driver 433. The first clamping driver 433 is used to drive the first movable clamping jaw 432 to rotate toward or away from the first fixed clamping jaw 432 to clamp or release the busbar.

[0054] like Figure 3 As shown, optionally, the clamping mechanism 2 includes a mounting bracket 21, a pressure plate 22, a clamping block 23 and a clamping drive 24, wherein: the pressure plate 22 is fixedly mounted on the mounting bracket 21. The clamping block 23 is slidably connected to the mounting bracket 21 and is drivingly connected to the driving end of the clamping drive 24. The busbar passes between the clamping block 23 and the pressure plate 22, and the clamping drive 24 is used to drive the clamping block 23 to slide toward or away from the pressure plate 22 to clamp or release the busbar.

[0055] As known to those skilled in the art, when the busbars included in the feeding mechanism are almost used up, the tray needs to be replaced. In order to ensure that the busbars can be continuously supplied, when the busbars on the old tray are cut off and the old tray is taken away, the ends of the busbars left after the cut off need to be connected with the free ends of the busbars on the new tray, and a connection scar will be left at the connection, that is, warping and / or thickness changes will occur at this location.

[0056] like Figures 2 to 3 As shown, optionally, the busbar preparation device in the embodiment of the present application further includes a scar detection assembly 5 mounted on the mounting bracket 21 of the clamping mechanism 2, and the scar detection assembly 5 is located between the pressure plate 23 and the cutting mechanism 3. The busbar passes through the clamping mechanism 2 and then through the scar detection assembly 5, and continues to be pulled backward after the scar detection is performed by the scar detection assembly 5.

[0057] Since the thickness of the busbar at the scar location is greater than the thickness of the busbar at other locations. Optionally, the scar detection assembly 5 includes a lower roller 51, an upper roller 52, a fixed block 53, a sensing rod 54, a spring and a sensor 55, wherein: the lower roller 51 is rotatably mounted on the mounting bracket 21. The fixed block 53 is arranged on the mounting bracket 21, the sensing rod 54 is vertically liftably connected to the fixed block 53, and the spring is sleeved on the sensing rod 54, wherein the upper end of the spring abuts against the fixed block 53, and the lower end of the spring abuts against the limit step on the sensing rod 54. The upper roller 52 is rotatably connected to the lower end of the sensing rod 54, and the busbar passes between the upper roller 52 and the lower roller 51. The upper roller 52 elastically presses the busbar against the lower roller 51 under the pressure of the spring. The sensor 55 is mounted on the mounting bracket 21 and is located above the sensing rod 54 . When there is a scar on the bus bar between the upper roller 52 and the lower roller 51 , the sensing rod 54 rises to a predetermined height to trigger the sensor 55 .

[0058] By arranging the scar detection assembly 5 on the mounting bracket 21 of the clamping mechanism 2, the detection and positioning of the scar on the busbar is realized, and the busbar with the scar is prevented from flowing into the subsequent process. Specifically, the busbar passes between the upper roller 52 and the lower roller 51 under the traction of the traction mechanism 1, and is elastically clamped by the upper roller 52 and the lower roller 51. When there is no scar on the busbar passing through the upper roller 52 and the lower roller 51, the upper end of the sensing rod 54 is maintained at a non-triggering position away from the sensor 55. When there is a scar on the busbar passing through the upper roller 52 and the lower roller 51, the sensing rod 54 is lifted upward to a predetermined height due to the increase in the thickness of the busbar, thereby approaching and triggering the sensor 55, and the sensor 55 generates a sensing signal. The sensor 55 can be, for example, a proximity sensor or a photoelectric sensor.

[0059] Of course, the scar detection component 5 is not integrated and installed on the mounting bracket 21 of the clamping mechanism 2, and it only needs to be arranged between the cutting mechanism 3 and the feeding mechanism. For example, in another optional embodiment, the scar detection component 5 includes an independent mounting frame. The lower roller 51 is rotatably mounted on the mounting frame, the fixed block 53 is arranged on the mounting frame, the sensing rod 54 is connected to the fixed block 53 in a vertical direction and can be raised and lowered, and the spring is sleeved on the sensing rod 54. The upper end of the spring abuts on the fixed block 53, and the lower end of the spring abuts on the limiting step on the sensing rod 54. The upper roller 52 is rotatably connected to the lower end of the sensing rod 54, and the bus bar passes between the upper roller 52 and the lower roller 51. The upper roller 52 elastically presses the bus bar against the lower roller 51 under the pressure of the spring. The sensor 55 is mounted on the mounting frame and is located above the sensing rod 54.

[0060] Similarly, when there is a scar on the bus bar between the upper roller 52 and the lower roller 51 , the sensing rod 54 rises to a predetermined height to trigger the sensor 55 , thereby realizing automatic detection of the scar on the bus bar.

[0061] like Figure 2 As shown, optionally, the cutting mechanism 3 includes a first bottom plate 31, a second bottom plate 32, a second translation module 33, a translation mounting frame 34, a concave die mounting plate 35, a convex die mounting plate 36 and a lifting module 37, wherein:

[0062] The second bottom plate 32 is slidably connected to the first bottom plate 31 and can slide along a second horizontal direction, which is perpendicular to the first horizontal direction. The second translation module 33 is arranged on the first bottom plate 31 and is transmission-connected to the second bottom plate 32, and the translation mounting frame 34 is arranged on the second bottom plate 32. The male mold mounting plate 36 and the female mold mounting plate 35 are arranged up and down, and one of them is fixedly mounted on the translation mounting frame 34. The lifting module 37 is installed on the translation mounting frame 34 and is transmission-connected to the other of the male mold mounting plate 36 and the female mold mounting plate 35, and the busbar passes between the male mold mounting plate 36 and the female mold mounting plate 35.

[0063] The female mold mounting plate 35 has at least two cavities of different shapes spaced apart in the second horizontal direction, and the male mold mounting plate 36 has at least two male molds corresponding to the cavities. The lifting module 37 is used to drive the male mold mounting plate 36 and the female mold mounting plate 35 to move closer to or away from each other, so that the male mold and the corresponding cavity are molded or separated.

[0064] The second translation module 33 is used to drive the second bottom plate 32 to slide, so as to drive one of the cavities and the corresponding punch to move to the upper and lower sides of the busbar. When the punch is molded with the corresponding cavity, a busbar with an end having a corresponding shape is punched out.

[0065] For example, Figure 4 As shown, the die mounting plate 35 is arranged along the second horizontal direction (such as Figure 4 Two cavities are arranged at intervals (in the Y-axis direction), namely, a rounded cavity 351 and a right-angle cavity 352. Correspondingly, the convex mold plate mounting plate 36 has two convex molds, namely, a rounded convex mold corresponding to the rounded cavity 351 and a right-angle convex mold corresponding to the right-angle cavity 352. When the second translation module 33 drives the translation mounting frame 34 to translate to the first punching position, the rounded cavity 351 and the rounded convex mold move to the upper and lower sides of the busbar, thereby punching out a busbar with a rounded end. When the second translation module 33 drives the translation mounting frame 34 to translate to the second punching position, the right-angle cavity 352 and the right-angle convex mold move to the upper and lower sides of the busbar, thereby punching out a busbar with a right-angle end.

[0066] It can be seen that, by setting the cutting mechanism 3 , the busbar preparation device of the embodiment of the present application can prepare busbars with ends of different shapes.

[0067] The second translation module 33 can adopt various existing linear drive modules that can drive the second bottom plate 32 to slide. The first lifting module 37 can adopt various existing linear drive modules that can drive the male die mounting plate 36 or the female die mounting plate 35 to rise and fall.

[0068] like Figure 1 As shown, optionally, the traction mechanism 1 includes a fourth translation module 11, a second mounting plate 12 and a second clamping assembly 13, wherein the second mounting plate 12 is connected to the driving end of the fourth translation module 11, and the second clamping assembly 13 is arranged on the second mounting plate 12. The fourth translation module 11 is configured to drive the second mounting plate 12 to translate along the first horizontal direction, so as to drive the second clamping assembly 13 to clamp the free end of the busbar from the cutting mechanism 3, and to pull the busbar away from the cutting mechanism 3.

[0069] like Figure 5 As shown, optionally, the second clamping assembly 13 includes a second fixed jaw 131, a second movable jaw 132 and a second clamping driver 133, wherein the second clamping driver 133 is disposed on the second mounting plate 12. The second fixed jaw 131 is fixedly connected to the mounting plate 132, and the second movable jaw 132 is hinged on the second mounting plate 12 and connected to the driving end of the second clamping driver 133. The second clamping driver 133 is used to drive the second movable jaw 132 to rotate toward or away from the second fixed jaw 131 to clamp or release the busbar.

[0070] Continue to refer Figure 5 As shown, optionally, a feeding mechanism, a pressing mechanism 2, a cutting mechanism 3 and a clamping mechanism 4 are provided on both sides of the traction mechanism 1. The second clamping assemblies 13 are provided in two groups, and the two groups of second clamping assemblies 13 are symmetrically arranged, and each group of second clamping assemblies 13 is used to clamp the free end of the busbar from the cutting mechanism 3 on the corresponding side, and to pull the busbar away from the corresponding cutting mechanism 3.

[0071] By arranging two sets of feeding mechanisms, pressing mechanisms 2, cutting mechanisms 3 and clamping mechanisms 4 on both sides of the traction mechanism 1, the traction mechanism 1 can clamp the busbar from the cutting mechanism 3 on any side. In this way, when the busbar of the feeding mechanism 3 on one side is exhausted and the material tray needs to be replaced, the traction mechanism 1 can clamp the busbar from the clamping mechanism 3 on the other side, thereby avoiding feeding interruption and improving processing efficiency.
