DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the process of producing solar cells by a stack welding machine, it is necessary to perform the steps of straightening, cutting, punching and bending the wound busbars. Among them, the step of cutting the busbars involves a busbar cutting module. The existing busbar cutting module can only pull and cut the busbars from one direction, which is inefficient and directly affects the production efficiency of the stack welding machine. To solve this problem, a busbar bidirectional cutting module is provided below.

[0021] refer to Figure 1 The busbar bidirectional cutting module includes a base 1, a transfer positioning plate 2, two material setting devices 4, two cutting devices 5 and a bidirectional pulling device 3 installed on the base 1.

[0022] A busbar unwinding module, a material setting device 4, a cutting device 5, a bidirectional pulling device 3, another cutting device 5, another material setting device 4 and another busbar unwinding module are sequentially arranged along the length direction of the base 1, wherein the transfer positioning plate 2 is arranged directly below the bidirectional pulling device 3, and the busbar unwinding module is not shown in the figure.

[0023] The bidirectional pulling device 3 pulls the busbar back and forth between the two material setting devices 4 and the two cutting devices 5. The busbar is straightened under the clamping and pulling action of the bidirectional pulling device 3 and the material setting device 4. The cutting device 5 cuts off the straightened busbar. The cut busbar is placed on the transfer positioning plate 2, waiting for the busbar handling module to move it away. One reciprocating action of the bidirectional pulling device 3 can cut two busbars, thereby doubling the pulling and cutting efficiency of the busbar.

[0024] Specifically, refer to Figure 1 , Figure 2 and Figure 3 .

[0025] The transfer positioning plate 2 is arranged in the central area of ​​the base 1, between the two busbar unwinding modules, and has a narrow rectangular top wall, and the length direction is parallel to the horizontal X-axis direction, and is used to support and position the cut busbars.

[0026] The bidirectional material pulling device 3 includes a first X-axis driver 31 and a bidirectional clamping mechanism 32 installed on the actuator of the first X-axis driver 31. The bidirectional clamping mechanism 32 is driven by the first X-axis driver 31 to move linearly back and forth above the transfer positioning plate 2. The bidirectional clamping mechanism 32 can clamp and release the busbar from two directions. When the bidirectional clamping mechanism 32 is located at one end of the transfer positioning plate 2, the bidirectional clamping mechanism 32 clamps a busbar from a busbar unwinding module and drives the first X-axis driver 31 to release the busbar. The device 31 pulls the busbar to the transfer positioning plate 2. At this time, the bidirectional clamping mechanism 32 is located at the other end of the transfer positioning plate 2. Then the bidirectional clamping mechanism 32 directly clamps a busbar from another busbar unwinding module, and pulls the busbar to the transfer positioning plate 2 in the opposite direction through the action of the first X-axis driver 31. Compared with the traditional busbar cutting module, the reciprocating action of the bidirectional clamping mechanism 32 can pull a busbar of twice the length, thereby greatly improving the pulling efficiency of the busbar.

[0027] The two material fixing devices 4 are symmetrically arranged at the two ends of the transfer positioning plate 2 along the X-axis direction. The rolled busbar is released toward the material fixing device 4 through the busbar unwinding module. The material fixing device 4 is used to clamp the busbar when the bidirectional pulling device 3 pulls the busbar of a predetermined length, so that the busbar stops unwinding. At this time, the two ends of the busbar are clamped by the bidirectional pulling device 3 and the material fixing device 4 respectively, and the bidirectional pulling device 3 applies a force to the busbar away from the material fixing device 4, so that the busbar between the two is straightened, so that it is easy to be cut at a fixed length.

[0028] The two cutting devices 5 are respectively arranged between each material fixing device 4 and the transfer positioning plate 2, including a second X-axis driver 51 and a cutting module 52 installed on the execution part of the second X-axis driver 51. The cutting module 52 is used to cut the busbar in a straight state. The second X-axis driver 51 is used to drive the cutting module 52 to approach the material fixing device 4 on the side after the busbar is cut off, so that the broken end of the busbar is exposed in front of the cutting module 52, so as to facilitate clamping when the two-way pulling device 3 is reset. When the broken end of the busbar is pulled to a preset position by the two-way pulling device 3 and the free end of the busbar is fixed by the material fixing device 4, the second X-axis driver 51 drives the cutting module 52 away from the material fixing device 4 on the side, and then cuts the busbar.

[0029] In addition, reference Figure 8 and Fig. 9 A first guide wheel 11, a second guide wheel 12, a first guide roller group 13 and a second guide roller group 14 are sequentially arranged between the busbar unwinding module and the fixing device 4. The axes of the first guide wheel 11 and the second guide wheel 12 are arranged along the Y-axis direction, the Y-axis direction is horizontal and perpendicular to the X-axis direction, the first guide roller group 13 includes two guide rollers whose axes are arranged along the Y-axis direction and arranged side by side along the Z-axis direction, the second guide roller group 14 includes two guide rollers whose axes are arranged along the Z-axis direction and arranged side by side along the Y-axis direction, and the Z-axis direction is vertical.

[0030] The rolled busbar starts from the busbar unwinding module, is guided by the first guide wheel 11, the second guide wheel 12, the first guide roller group 13 and the second guide roller group 14 in sequence, and enters the material setting device 4.

[0031] For the specific structure of the transfer positioning plate 2, please refer to Figure 3 As shown in the enlarged partial view, the transfer positioning plate 2 includes a slat 21 and a plurality of positioning column groups 22 installed on the slat 21 and distributed along the X-axis direction. Each positioning column group 22 includes two positioning columns arranged in pairs along the Y-axis direction. The cut bus bar is placed on the slat 21, and the two sides of the bus bar respectively abut against the outer circumferential surfaces of the two positioning columns to achieve the positioning of the bus bar.

[0032] In addition, the distance between the two positioning columns can be adjusted. In the present embodiment, the positioning columns are bolts, and a plurality of bolt hole groups 23 corresponding to each positioning column are provided on the slat 21. Each bolt hole group 23 includes a row of bolt holes distributed along the C-axis direction. The C-axis is horizontally arranged and between the X-axis and the Y-axis. By installing the positioning columns inside different bolt holes in the C-axis direction, the distance between two adjacent positioning columns in the Y-axis direction can be changed, thereby adapting to bus bars of different widths.

[0033] In addition, a groove 24 is provided on the slat 21, which is recessed downward and surrounds the bolt hole group 23. The groove 24 is used to embed the bottom end of the positioning column so that the side wall of the busbar can contact the outer peripheral surface of the positioning column without contacting the lower edge of the positioning column, thereby avoiding burrs on the lower edge of the positioning column affecting the positioning of the busbar, or avoiding the verticality of the positioning column affecting the positioning of the busbar.

[0034] For the specific structure of the bidirectional clamping nozzle mechanism 32, refer to Figure 3 , Figure 4 and Figure 5 The bidirectional nozzle mechanism 32 includes a material pulling base plate 321, two material pulling nozzles 322 and a bidirectional nozzle driver 323. The material pulling base plate 321 is fixedly connected to the execution part of the first X-axis driver 31. The two material pulling nozzles 322 are respectively arranged on both sides of the material pulling base plate 321 along the X-axis direction. The bidirectional nozzle driver 323 is fixedly connected to the material pulling base plate 321. The execution part of the bidirectional nozzle driver 323 is transmission-connected to the two material pulling nozzles 322, so that the two material pulling nozzles 322 move synchronously and in opposite directions.

[0035] Specifically, refer to Figure 5 The material drawing clamp 322 includes a relatively long driving rod 325, a relatively short driven rod 326 and a clamp rotating shaft 327, wherein one end of the driving rod 325 is connected to one end of the driven rod 326 and the two are relatively perpendicular, the clamp rotating shaft 327 is arranged at the connection between the driving rod 325 and the driven rod 326, the clamp rotating shaft 327 is connected to the material drawing bottom plate 321 so that the material drawing clamp 322 is rotatably connected to the material drawing bottom plate 321, and the bidirectional clamp driver 323 adopts an actuator arranged along the X-axis direction. The bidirectional clamp driver 32 The actuator of 3 is connected to the driving rod 325 through a slide groove arranged along the Z-axis direction, so that the linear motion of the actuator of the bidirectional clamping nozzle driver 323 along the X-axis direction can be converted into the rotational motion of the driving rod 325 around the X-axis, and the driven rod 326 rotates following the driving rod 325. When the driving rod 325 on one side of the pulling base plate 321 approaches the pulling base plate 321 to clamp the bus bar, the driving rod 325 on the other side of the pulling base plate 321 moves away from the pulling base plate 321 to release the bus bar, so that the two pulling nozzles 322 can alternately clamp and release the bus bar.

[0036] Furthermore, in order to improve the friction between the material pulling nozzle 322, the material pulling bottom plate 321 and the bus bar, Figure 6An elastic rubber strip 324 is embedded on the side of the material pulling base plate 321 facing the material pulling nozzle 322. When the material pulling nozzle 322 approaches the material pulling base plate 321, the bus bar presses the elastic rubber strip 324 under the extrusion of the material pulling nozzle 322. The elastic rubber strip 324 is clamped between the bus bar and the material pulling base plate 321. At this time, there is a large friction between the elastic rubber strip 324 and the bus bar, thereby increasing the friction between the material pulling base plate 321 and the bus bar.

[0037] For the specific structure of the metering device 4, refer to Figure 5 , Figure 8 , Fig. 9 The material fixing device 4 includes a material fixing base plate 41, a material fixing nozzle 42 and a one-way nozzle driver 43. The material fixing base plate 41 is fixedly connected to the base 1, and the one-way nozzle driver 43 is fixedly connected to the material fixing base plate 41. The execution part of the one-way nozzle driver 43 is connected to the material fixing nozzle 42 so that the material fixing nozzle 42 rotates to approach or move away from the material fixing base plate 41, thereby performing the action of clamping and releasing the bus bar.

[0038] Specifically, the structure of the material fixing device 4 is roughly the same as that of the bidirectional clamping nozzle mechanism 32. The material fixing nozzle 42 also includes a driving rod 325, a driven rod 326 and a clamping nozzle shaft 327, and the positions and connection relationships of the three are consistent. Under the action of the unidirectional clamping nozzle driver 43, the material fixing nozzle 42 approaches or moves away from the material fixing base plate 41, thereby clamping or releasing the bus bar.

[0039] For the specific structure of the cutter module 52, refer to Figure 5 , Figure 7 , Fig.10 The cutting tool module 52 includes a cutting base plate 521 , a cutting tool 522 , and a push rod driver 524 connected to the cutting tool 522 via a tool push rod 523 .

[0040] Among them, the tool push rod 523 can be rotatably connected to the cutting base plate 521, the push rod driver 524 adopts a cylinder, and the tool push rod 523 is connected to the actuator of the push rod driver 524 through a vertical slide groove, so that the linear motion of the actuator of the push rod driver 524 can be converted into the rotational motion of the tool push rod 523, and then the tool push rod 523 drives the cutting tool 522 to approach the cutting base plate 521, so that the cutting tool 522 cuts off the bus bar located on the cutting base plate 521.

[0041] Among them, the cutting tool 522 can be connected to the tool push rod 523 by rotational motion or linear motion. One end of the cutting tool 522 has a blade, and the other end of the cutting tool 522 is connected to the tool push rod 523 through an elastic member 525. The elastic member 525 is preferably a spring. The tool push rod 523 and the cutting tool 522 are provided with grooves for constraining the position of the spring. The elastic member 525 located between the tool push rod 523 and the cutting tool 522 always has an internal force to extend itself, so that the blade of the cutting tool 522 always has an internal force to move in a direction away from the tool push rod 523 (close to the cutting base plate 521).

[0042] When the blade of the cutting tool 522 contacts the cutting base plate 521, the tool push rod 523 can continue to move to apply a greater thrust to the cutting tool 522 through the elastic member 525, ultimately making the force between the cutting tool 522 and the cutting base plate 521 between the blade being destroyed and the bus bar being cut off, thereby effectively cutting off the bus bar while protecting the blade from damage.

[0043] Furthermore, the cutting device 5 also includes a detection switch 53 and a bus bar bracket 54 arranged in front of the cutting knife module 52 along the X-axis direction. The detection switch 53 and the bus bar bracket 54 are both installed on the execution part of the second X-axis driver 51. The height of the bus bar bracket 54 is lower than the height of the cutting base plate 521, the height of the detection switch 53 is higher than the height of the cutting base plate 521, and the detection switch 53 is arranged toward the bus bar bracket 54.

[0044] After the busbar is cut by the cutting tool 522, as the second X-axis driver 51 drives the cutting tool module 52 to retreat, the broken end of the busbar moves to the busbar bracket 54. At this time, the busbar bracket 54 supports the bottom wall of the busbar to prevent the broken end of the busbar from sagging, and assists the pulling clamp 322 to clamp the broken end of the busbar.

[0045] The detection switch 53 is preferably a metal proximity switch, which is used to detect whether there is a bus bar on the bus bar bracket 54. When the detection switch 53 detects the bus bar, the second X-axis driver 51 stops moving. At this time, the broken end of the bus bar is exactly located at the working position of the material pulling clamp 322.

[0046] In summary, combined with Figures 1 to 10The busbar bidirectional cutting module moves the bidirectional clamping mechanism 32 through the first X-axis driver 31, and clamps a broken end of a busbar from a busbar bracket 54 in front of a cutting module 52 at one end of the slat 21, and then pulls the busbar to a predetermined length. After the busbar is clamped and tightened by the fixing device 4, the cutting device 5 cuts the busbar, and the bidirectional clamping mechanism 32 releases the busbar so that the busbar stays at the specified position on the slat 21. At this time, the bidirectional clamping mechanism 32 is at the other end of the slat 21. While the first X-axis driver 31 drives the bidirectional clamping mechanism 32 to return, the bidirectional clamping mechanism 32 can cooperate with another fixing device 4 and another cutting device 5 to complete the fixed-length cutting of another busbar, thereby exponentially improving the cutting efficiency of the busbar.
