Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell production equipment, and in particular to a flattening mechanism and welding equipment. Background Art

[0002] In the production process of photovoltaic cells, there is a process of using welding equipment to weld the cells and welding wires to form a cell string. Before the welding wires are welded to the cells, a flattening process needs to be added to the production process of photovoltaic cells. Through the flattening process, the preset parts of the welding wires can be flattened to meet the stacking requirements of the cells.

[0003] In the related art, welding equipment usually includes a flattening mechanism for flattening the welding wire.

The driving member can flatten the welding wire by driving the pressure head.

Since the spacing between two adjacent welding wires in a small number of welding wires is relatively large, the spacing between two adjacent pressure heads in each pressure head corresponding to each welding wire is also relatively large. However, when the number of welding wires is large, since the size of the battery cell is fixed, the spacing between two adjacent welding wires is relatively small, and since the spacing between two adjacent pressure heads in the flattening mechanism is relatively large, each pressure head cannot correspond to each welding wire one by one, and thus cannot achieve one-to-one flattening of each welding wire.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0047] As described in the background of this application, in the photovoltaic cell production process, there is a process of using welding equipment to weld the cell and the welding wire to form a cell string. Before the welding wire and the cell are welded, it is necessary to add a flattening process in the photovoltaic cell production process, through which the preset part of the welding wire can be flattened to meet the stacking requirements of the cell.

[0048] In the related art, welding equipment usually includes a flattening mechanism for flattening the welding wire. The flattening mechanism includes a plurality of driving members arranged in sequence and a pressure head connected to the driving members by transmission. The driving member can flatten the welding wire by driving the pressure head.

[0049] The flattening mechanism in the related art is only suitable for flattening operations with a small number of welding wires. Since the spacing between two adjacent welding wires in a small number of welding wires is relatively large, the spacing between two adjacent pressure heads in each pressure head corresponding to each welding wire is also relatively large. However, when the number of welding wires is large, since the size of the battery cell is fixed, the spacing between two adjacent welding wires is relatively small, and since the spacing between two adjacent pressure heads in the flattening mechanism is relatively large, each pressure head cannot correspond to each welding wire one by one, and thus cannot achieve one-to-one flattening of each welding wire.

[0050] In view of the above-mentioned problems, the present application provides a flattening mechanism to solve the problem that the flattening mechanism in the related art cannot flatten a large number of welding wires one by one.

[0051] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0052] like Figures 1 to 5 As shown, the flattening mechanism 100 includes a mounting frame 1 and a flattening actuator 2, wherein the flattening actuator 2 moves along a first direction ( Figure 3 The first pressing head 22 is provided with a plurality of pressing heads 22 and a second pressing head 23 in sequence. The flattening actuator 2 includes a driving member 21, a first pressing head 22 and a second pressing head 23. The driving member 21 and the second pressing head 23 are provided on the mounting frame 1. The driving member 21 is used to drive the first pressing head 22 to move closer to or away from the second pressing head 23. The first pressing head 22 is used to flatten the welding wire together with the second pressing head 23 when moving closer to the second pressing head 23.

[0053] The two driving members 21 in two adjacent flattening actuators 2 are arranged adjacent to each other, and the two adjacent driving members 21 are arranged in a second direction ( Figure 3 The driving members 21 are staggered in the Z direction (in the Z direction), and a projection of one of two adjacent driving members 21 in the second direction is at least partially located on the other.

[0054] In the present application, since the two driving members 21 in the two adjacent flattening actuators 2 in the flattening mechanism 100 are arranged adjacent to each other, and since the two adjacent driving members 21 are staggered in the second direction different from the first direction, and since the projection of one of the two adjacent driving members 21 in the second direction is at least partially located on the other, such an arrangement can ensure that there is no spacing between the two adjacent driving members 21 in the first direction, that is, the two adjacent driving members 21 can be compactly arranged in the first direction, and thus the driving members 21 in the entire flattening mechanism 100 can be compactly arranged in the first direction, so that the first pressure heads 22 can be compactly arranged in the first direction, that is, the spacing between any two adjacent first pressure heads 22 in the first direction can be reduced, and thus it is beneficial to make the spacing between the two adjacent first pressure heads 22 adapt to the spacing between the two adjacent welding wires in a larger number of welding wires, and it is beneficial to make each first pressure head 22 correspond one-to-one with each welding wire, and thus it is beneficial to achieve one-to-one flattening of a larger number of welding wires.

[0055] As for the driving member 21 , in the embodiment of the present application, the driving member 21 may be any one of a pneumatic cylinder, an electric cylinder and a hydraulic cylinder, and the embodiment of the present application does not specifically limit the type of the driving member 21 .

[0056] Regarding the first direction and the second direction, further, the first direction is perpendicular to the second direction.

[0057] Such an arrangement can reduce the space occupied by the driving member 21 , especially in the direction perpendicular to the first direction and the second direction, and is conducive to facilitating the arrangement of the driving member 21 in this direction.

[0058] In the embodiment of the present application, the first direction may be a horizontal left-right direction or a front-back direction, and the second direction may be an up-down direction, or the second direction may be a front-back or left-right direction that is perpendicular to the first direction and horizontal; or the first direction and the second direction may both be any other direction that is different from the horizontal direction and the up-down direction. The specific direction settings of the first direction and the second direction are relatively flexible, and the embodiment of the present application does not limit the specific directions of the first direction and the second direction.

[0059] For the driving member 21, further, each first pressing head 22 in each flattening execution assembly 2 is sequentially arranged along the first direction; Figure 5 As shown, the driving member 21 is used to drive along the third direction ( Figure 5 The third direction is perpendicular to the second direction.

[0060] Such a configuration can, to a certain extent, reduce the output path of at least one output action of the driving member 21, facilitate the output of the output action of the driving member 21, and at the same time, can also reduce the space occupied by the driving member 21 in the third direction, thereby facilitating the reduction of the space occupied by the entire flattening mechanism in the third direction.

[0061] In other embodiments, the third direction may be the same as the second direction, and the angle between the third direction and the second direction may be an acute angle or an obtuse angle, that is, the third direction and the second direction may not be perpendicular. The setting between the third direction and the second direction is relatively flexible, and specifically, it can be set according to actual use requirements, and this embodiment of the present application will not be elaborated in detail.

[0062] like Figures 1 to 4 As shown, part of the flattening actuator components 2 in each flattening actuator component 2 constitutes a first module 10, and another part of the flattening actuator components 2 constitutes a second module 20, each driving member 21 in the first module 10 and each driving member 21 in the second module 20 are disposed on both sides of each first pressing head 22, and each driving member 21 in the first module 10 and each driving member 21 in the second module 20 are located on the same side of each first pressing head 22 in the arrangement direction of the first pressing head 22 and the second pressing head 23.

[0063] Such an arrangement, compared with the arrangement of each driving member 21 in the first module 10 and each driving member 21 in the second module 20 on the same side of each first pressure head 22, is conducive to further arranging each driving member 21 in the entire flattening mechanism 100 compactly in the first direction. On the one hand, it is conducive to further arranging each first pressure head compactly in the first direction, and further conducive to further adapting the spacing between two adjacent first pressure heads to the spacing between two adjacent welding wires in a larger number of welding wires. On the other hand, it is conducive to further reducing the space occupied by each driving member 21 in the entire flattening mechanism 100 in the first direction, and further conducive to further facilitating the arrangement of each driving member 21 in the first direction.

[0064] Furthermore, if Figure 2 As shown, at least part of two adjacent flattening actuators 2 in the first module 10 are located between two adjacent flattening actuators 2 in the second module 20 in the first direction.

[0065] Such an arrangement is conducive to further compactly arranging each driving member 21 in the entire flattening mechanism 100 in the first direction. On the one hand, it is conducive to further compactly arranging each first pressure head in the first direction, and further conducive to further adapting the distance between two adjacent first pressure heads to the distance between two adjacent welding wires in a larger number of welding wires. On the other hand, it is conducive to further reducing the space occupied by each driving member 21 in the entire flattening mechanism 100 in the first direction, and further conducive to further facilitating the arrangement of each driving member 21 in the first direction.

[0066] In a preferred embodiment, Figure 2 As shown, in the first module 10, only one group of two adjacent flattening actuators 2 are located on one side of the second module 20 in the first direction, and the remaining two adjacent flattening actuators 2 are located between the two adjacent flattening actuators 2 in the second module 20 in the first direction. This arrangement facilitates the arrangement between the first module 10 and the second module 20.

[0067] In other embodiments, the first module 10 is located on one side of the second module 20 in the first direction, and each driving member 21 in the first module 10 is located on one side of each driving member 21 in the second module 20 in the first direction. This arrangement facilitates the arrangement between the first module 10 and the second module 20.

[0068] Furthermore, if Figure 3 and Figure 4 As shown, the driving members 21 in the two flattening actuator components 2 arranged with one flattening actuator component 2 between them in the first module 10 are aligned in the first direction; and / or, the driving members 21 in the two flattening actuator components 2 arranged with one flattening actuator component 2 between them in the second module 20 are aligned in the first direction.

[0069] Such an arrangement, especially in the direction perpendicular to the first direction and the second direction, is conducive to avoiding excessively diffuse arrangement of the driving members 21 in two flattening actuators 2 arranged with one flattening actuator 2 between them, thereby helping to further reduce the space occupied by the driving members 21 in this direction, and further facilitating the arrangement of the driving members 21 in this direction.

[0070] In a preferred embodiment, Figure 3 and Figure 4 As shown, the driving members 21 in the two flattening actuator components 2 arranged with one flattening actuator component 2 between them in the first module 10 are aligned in the first direction; and the driving members 21 in the two flattening actuator components 2 arranged with one flattening actuator component 2 between them in the second module 20 are aligned in the first direction.

[0071] Such a configuration is beneficial to further avoid excessively diffuse arrangement of the driving members 21 in two flattening actuators 2 that are arranged one flattening actuator 2 apart, thereby helping to further reduce the space occupied by the driving members 21 in this direction, thereby further facilitating the arrangement of the driving members 21 in this direction.

[0072] For the flattening actuator 2, further, as Figure 2 , Figure 4 and Figure 5 As shown, the flattening actuator 2 also includes a connecting rod structure 24, one end of the connecting rod structure 24 is connected to the driving member 21, and the other end is connected to the first pressing head 22. The driving member 21 is used to drive the first pressing head 22 to move closer to or away from the second pressing head 23 through the connecting rod structure 24.

[0073] With such arrangement, the connection rod structure 24 can increase the spacing between the driving member 21 and the first pressing head 22 , which is beneficial to avoid excessive concentration of the driving member 21 and the first pressing head 22 and facilitates the arrangement of the driving member 21 and the first pressing head 22 .

[0074] In other embodiments, the output end of the driving member 21 is directly connected to the first pressing head 22. In this configuration, there is no need to provide the connecting rod structure 24, which can simplify the structural composition of the flattening actuator 2 and further reduce the manufacturing cost.

[0075] Furthermore, if Figure 5 and Figure 6 As shown, the connecting rod structure 24 includes a connecting rod 241 and a piston shaft 242. One end of the connecting rod 241 is connected to the driving member 21, and the connecting rod 241 is hinged to the mounting frame 1 at a hinged position.

[0076] The piston shaft 242 is guided and arranged on the mounting frame 1 , one end of the piston shaft 242 is connected to the first pressure head 22 , and the other end is connected to the connecting rod 241 at a connecting position, which is spaced apart from the above-mentioned hinge position in a direction different from the length direction of the connecting rod 241 .

[0077] In this way, when the driving member 21 drives the connecting rod 241 to rotate around the hinge axis at the above-mentioned hinge position, the above-mentioned connecting position will also rotate around the hinge axis at the above-mentioned hinge position, and because the piston shaft 242 is connected to the connecting rod 241 at the connecting position, during this process, through the rotation of the connecting position around the hinge axis at the above-mentioned hinge position, the connecting rod 241 can drive the piston shaft 242 to move along the guiding direction of the mounting frame 1, and then the piston shaft 242 can drive the first pressure head 22 connected thereto to move closer to or away from the second pressure head 23.

[0078] According to the above description, setting the connecting rod structure 24 to include a connecting rod 241 and a piston shaft 242 is conducive to facilitating the driving member 21 to drive the first pressure head 22 to move closer to or away from the second pressure head 23 by driving the connecting rod structure 24. At the same time, it is also conducive to simplifying the specific structure of the connecting rod structure 24 and facilitating the processing of the connecting rod structure 24.

[0079] In a preferred embodiment, Figure 6 As shown, the mounting frame 1 includes a mounting frame body 11 and a fixed shaft 12 disposed on the mounting frame body 11. Each connecting rod 241 in each flattening actuator 2 is provided with a through hole. The fixed shaft 12 sequentially passes through each through hole on each connecting rod 241 along a first direction to realize the hinge of each connecting rod 241 on the mounting frame 1. The above-mentioned hinge position is also the position where the through hole on the connecting rod 241 is located. The fixed shaft 12 sequentially passes through each through hole on each connecting rod 241 to realize the hinge of each connecting rod 241 on the mounting frame 1, which facilitates the hinge of each connecting rod 241 on the mounting frame 1.

[0080] In a preferred embodiment, Figure 6 As shown, the mounting frame 1 further includes a guide sleeve 13 disposed on the mounting frame body 11, the guide sleeve 13 is sleeved on the piston shaft 242, and the length direction of the guide sleeve 13 is along the second direction ( Figure 3 The guide sleeve 13 extends in the second direction (Z direction), that is, the guide sleeve 13 guides the piston shaft 242 along the second direction. The guide sleeve 13 is provided to guide the piston shaft 242, so that when the guide sleeve 13 is worn due to long-term use, only the guide sleeve 13 needs to be replaced, and the entire mounting frame 1 does not need to be replaced, which is conducive to reducing maintenance costs.

[0081] Regarding the connection between the piston shaft 242 and the connecting rod 241, in the embodiment of the present application, the connection between the piston shaft 242 and the connecting rod 241 can be any one of a ball joint, a pin joint and a hinge joint. The connection method between the piston shaft 242 and the connecting rod 241 is relatively flexible, and the embodiment of the present application does not make any specific limitations on this.

[0082] Furthermore, if Figure 6 As shown, a reset elastic member 3 is provided between the piston shaft 242 and the mounting frame 1 , and the reset elastic member 3 is used to drive the first pressing head 22 to move away from the second pressing head 23 through the elastic force generated by its own elastic deformation.

[0083] With such arrangement, on the basis of the driving member 21 driving the first pressing head 22 to move away from the second pressing head 23, the first pressing head 22 is driven to move away from the second pressing head 23 by the reset elastic member 3, which is beneficial to further ensure that the first pressing head 22 can move away from the second pressing head 23 to achieve reverse reset, and further beneficial to further ensure that the next operation of flattening the welding wire can be carried out smoothly.

[0084] In a preferred embodiment, Figure 6 As shown, the piston shaft 242 includes a piston shaft body 2421, a limiting sleeve 2422 sleeved and threadedly assembled on the piston shaft body 2421, the reset elastic member 3 and the guide sleeve 13 are both sleeved on the piston shaft body 2421, and the reset elastic member 3 is located between the guide sleeve 13 and the limiting sleeve 2422, one end of the reset elastic member 3 abuts against the guide sleeve 13, and the other end abuts against the limiting sleeve 2422, so that the reset elastic member 3 can be set between the piston shaft 242 and the mounting frame 1.

[0085] The limiting sleeve 2422 threadedly assembled on the piston shaft body 2421 not only enables the reset elastic member 3 to be arranged between the piston shaft 242 and the mounting bracket 1 , but also facilitates the installation and removal of the reset elastic member 3 on the piston shaft body 2421 .

[0086] Regarding the reset elastic member 3, in the embodiment of the present application, the reset elastic member 3 can be any one of a spring, an elastic rubber ring, etc. The type of the reset elastic member 3 can be selected flexibly, and the embodiment of the present application does not make any specific limitation on this.

[0087] The present application also provides a welding device, such as Figure 7 As shown, the welding equipment includes a flattening mechanism 100, which has the same structure as any of the flattening mechanisms 100 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, which will not be repeated in this embodiment.

[0088] In the present application, since the two driving members 21 in the two adjacent flattening actuators 2 in the flattening mechanism 100 are arranged adjacent to each other, and since the two adjacent driving members 21 are staggered in the second direction different from the first direction, and since the projection of one of the two adjacent driving members 21 in the second direction is at least partially located on the other, such an arrangement can ensure that there is no spacing between the two adjacent driving members 21 in the first direction, that is, the two adjacent driving members 21 can be compactly arranged in the first direction, and thus the driving members 21 in the entire flattening mechanism 100 can be compactly arranged in the first direction, so that the first pressure heads 22 can be compactly arranged in the first direction, that is, the spacing between any two adjacent first pressure heads 22 in the first direction can be reduced, and thus it is beneficial to make the spacing between the two adjacent first pressure heads 22 adapt to the spacing between the two adjacent welding wires in a larger number of welding wires, and it is beneficial to make each first pressure head 22 correspond one-to-one with each welding wire, and thus it is beneficial to achieve one-to-one flattening of a larger number of welding wires.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
