[0044] First, the X direction, Y direction and Z direction mentioned in the embodiment of the present application are shown in the attached drawings. Figure 4 The marked directions. Among them, the X direction, Y direction and Z direction intersect each other.

[0045] like Figure 1,like Figure 2 ,like Figure 3 、 Figure 4 and Figure 8 As shown, according to the first aspect of an embodiment of the present application, a welding strip flattening mechanism 100 is provided, comprising a first flattening component 1 and a second flattening component 2; the first flattening component 1 comprises a first pressing head 11; the second flattening component 2 comprises a second pressing head 21, the first pressing head 11 and the second pressing head 21 are arranged along the Z direction, and the welding strip is placed between the first pressing head 11 and the second pressing head 21; the edge of the first pressing head 11 can float in the Z direction relative to a preset position, and / or the edge of the second pressing head 21 can float in the Z direction relative to a preset position.

[0046] like Figure 2 As shown, the welding ribbon flattening mechanism 100 includes a first flattening component 1 and a second flattening component 2 .

[0047] Among them, the first flattening component 1 includes a first pressing head 11, and the second flattening component 2 includes a second pressing head 21. The first pressing head 11 and the second pressing head 21 are arranged along the Z direction, and a welding strip is placed between the first pressing head 11 and the second pressing head 21. That is to say, the first pressing head 11 of the first flattening component 1 can move along the Z direction, approaching or moving away from the second pressing head 21. The welding strip is placed between the first pressing head 11 and the second pressing head 21, and the first pressing head 11 approaches the second pressing head 21 along the Z direction. When the first pressing head 11 contacts the second pressing head 21 to extrude the welding strip, the welding strip is formed into a preset shape.

[0048] In a specific embodiment, the edge of the first pressing head 11 can float in the Z direction relative to a preset position. Specifically, the first pressing head 11 can rotate relatively, so that the edge of the first pressing head 11 can float in the Z direction. In other words, the angle of the working surface of the first pressing head 11 can be adjusted so that the working surface of the first pressing head 11 can fully contact the working surface of the second pressing head 21, thereby ensuring the pressing accuracy of the welding strip, thereby further improving the pressing quality of the welding strip.

[0049] In another specific embodiment, the edge of the second pressing head 21 can float in the Z direction relative to a preset position. Specifically, the second pressing head 21 can rotate relatively, so that the edge of the second pressing head 21 can float in the Z direction. In other words, the angle of the working surface of the second pressing head 21 can be adjusted so that the working surface of the second pressing head 21 can fully contact the working surface of the first pressing head 11, thereby ensuring the pressing accuracy of the welding strip, thereby further improving the pressing quality of the welding strip.

[0050] In another specific embodiment, the edge of the first pressing head 11 can float relative to the preset position along the Z direction; the edge of the second pressing head 21 can float relative to the preset position in the Z direction. The principle is the same as the above two embodiments, and this embodiment will not be repeated.

[0051] In one embodiment, the first flattening assembly 1 is located above the second flattening assembly 2 in the Z direction, and the working surface of the first pressing head 11 faces the working surface of the second pressing head 21 .

[0052] In an optional embodiment, the first flattening component 1 includes a first connecting rod 12, the first connecting rod 12 includes a first connecting end surface 121, and the first connecting end surface 121 is spherical; the first pressing head 11 is provided with a first connecting groove 111, the bottom surface of the first connecting groove 111 is arranged opposite to the working surface of the first pressing head 11, and the first connecting end surface 121 is located in the first connecting groove 111 and abuts against the bottom surface of the first connecting groove 111.

[0053] like Figure 1 and Figure 2 As shown, the first flattening assembly 1 includes a first pressing head 11 and a first connecting rod 12. The first pressing head 11 is provided with a first connecting groove 111. The bottom surface of the first connecting groove 111 is arranged opposite to the working surface of the pressing head, that is, the bottom surface of the first connecting groove 111 and the working surface coincide with each other in the Z direction; the first connecting rod 12 includes a first connecting end surface 121. The first connecting end surface 121 is located in the first connecting groove 111 and abuts against the bottom surface of the first connecting groove 111. The first connecting end surface 121 is spherical, so the bottom surface of the first connecting groove 111 can rotate relative to the first connecting end surface 121, and the first pressing head The working surface of 11 coincides with the bottom surface of the first connecting groove 111 in the Z direction, so the working surface of the first pressing head 11 can also rotate relative to the first connecting end surface 121, that is, the edge of the working surface of the first pressing head 11 can float in the Z direction relative to the position of the first connecting end surface 121. When the first pressing head 11 and the second pressing head 21 of the second flattening assembly 2 work together to extrude the welding strip, the angle of the working surface of the first pressing head 11 can be adjusted through the first connecting end surface 121, so that the first pressing head 11 and the second pressing head 21 are completely fitted together, thereby ensuring the flattening effect of the welding strip and improving the pressing quality of the welding strip.

[0054] In the above embodiment, the second pressing head 21 of the second flattening assembly 2 can be fixed on the base plate. Therefore, while ensuring the flatness of the second pressing head 21, it is only necessary to adjust the angle of the working surface of the first pressing head 11 to fully contact the second pressing head 21, thereby ensuring the pressing accuracy of the welding strip, thereby further improving the pressing quality of the welding strip.

[0055] In this embodiment, the preset position is the position where the first connection end surface 121 abuts against the bottom surface of the first connection groove 111 .

[0056] like Figure 1 and Figure 2 As shown, the first flattening component 1 is located above the second flattening component 2 in the Z direction, that is, in this embodiment, the end of the first connecting rod 12 away from the first connecting end face 121 is used to connect with the driving component 4, the first flattening component 1 is located above the second flattening component 2, the second pressure head 21 of the first flattening component 1 is fixed on the bottom plate, and the first flattening component 1 can approach or move away from the second flattening component 2 along the Z direction. When the working surface of the first pressure head 11 of the first flattening component 1 contacts the second pressure head 21 of the second flattening component 2, the first connecting end face 121 of the first connecting rod 12 can adjust the angle of the first pressure head 11 so that the first pressure head 11 is in full contact with the second pressure head 21.

[0057] In an optional embodiment, the second flattening component 2 also includes a mounting seat 22, and a second connecting groove 221 is provided on the mounting seat 22; the second pressing head 21 includes a main body 212 and a mounting rod 211, the working surface of the second pressing head 21 is located on the main body 212, and the mounting rod 211 is connected to an end of the main body 212 away from the working surface of the second pressing head 21, and the mounting rod 211 includes a second connecting end face 2111, the second connecting end face 2111 is a spherical surface, and the second connecting end face 2111 is embedded in the second connecting groove 221.

[0058] like Figure 4As shown, the second flattening assembly 2 also includes a mounting seat 22, and the mounting seat 22 is provided with a second connecting groove 221, and the second connecting groove 221 faces the second pressing head 21; the second pressing head 21 includes a body 212 and a mounting rod 211, the working surface of the second pressing head 21 is located on the body 212, and the mounting rod 211 is connected to an end away from the working surface of the second pressing head 21, that is, one end of the mounting rod 211 is connected to the body 212, and the other end of the mounting rod 211 has a second connecting end surface 2111, and the second connecting end surface 2111 is a spherical surface. The second connecting end surface 2111 is located in the second connecting groove 221 and is connected to the bottom of the second connecting groove 221. The second connecting end face 2111 is spherical, so the second connecting end face 2111 can rotate relative to the second connecting groove 221, so that the working surface of the second pressing head 21 can rotate relatively, that is, the edge of the working surface of the second pressing head 21 can float in the Z direction relative to the position of the second connecting end face 2111. When the first pressing head 11 and the second pressing head 21 work together to extrude the welding strip, the angle of the working surface of the second pressing head 21 can be adjusted through the second connecting end face 2111, so that the first pressing head 11 and the second pressing head 21 are completely fitted together, thereby ensuring the flattening effect of the welding strip and improving the pressing quality of the welding strip.

[0059] In this embodiment, the preset position is the position of the connection between the mounting rod 211 and the body 212 .

[0060] In an optional embodiment, a limiting portion 13 is provided at one end of the first connecting rod 12 away from the first connecting end face 121, and the first connecting rod 12 is sleeved with a shaft sleeve 14 and an elastic member 15, and the shaft sleeve 14 and the elastic member 15 are located between the first connecting end face 121 and the limiting portion 13, and the shaft sleeve 14 is close to the first connecting end face 121 relative to the elastic member 15.

[0061] In an embodiment where the first flattening component 1 is located above the second flattening component 2, a limiting portion 13 is provided at the end of the first connecting rod 12 away from the first connecting end face 121. The limiting portion 13 can be a nut. A thread is provided on the outer wall of the end of the first connecting rod 12 away from the first connecting end face 121. The nut is sleeved on the outer wall of the first connecting rod 12 and is connected with the thread. An elastic member 15 and a sleeve 14 are also sleeved on the first connecting rod 12. The first connecting rod 12 can slide along the Z direction relative to the elastic member 15 and the sleeve 14. The sleeve 14 is closer to the first connecting end face 121 relative to the elastic member 15. The sleeve 14 and the elastic member 15 are located between the first connecting end face 121 and the limiting portion 13.

[0062] Further explanation: the sleeve 14 is used to connect with the installation, and the elastic member 15 is located between the limit portion 13 and the sleeve 14. When the first connecting rod 12 moves along the Z direction, the limit portion 13 will squeeze the elastic member 15, so that the elastic member 15 provides a buffering force for the limit portion 13. Therefore, the elastic member 15 also provides a buffering force for the first pressure head 11, thereby providing a buffering effect when the first pressure head 11 contacts the welding strip, thereby preventing the first pressure head 11 from breaking the welding strip.

[0063] The elastic member 15 may be a coil spring.

[0064] In an optional embodiment, a limiting groove 122 is provided on the outer wall of the first connecting rod 12 close to the first connecting end surface 121, and a limiting protrusion 1112 is provided at one end of the first connecting groove 111 away from the bottom surface of the first connecting groove 111, and the limiting protrusion 1112 is embedded in the limiting groove 122.

[0065] like Figure 2 and Figure 3 As shown, a limiting groove 122 is provided on the outer wall of one end of the first connecting rod 12 close to the first connecting end face 121, and the limiting groove 122 extends radially along the first connecting rod 12; a limiting protrusion 1112 is provided at one end of the first connecting groove 111 away from the bottom surface of the first connecting groove 111, and the limiting protrusion 1112 extends radially along the first connecting groove 111, and the limiting protrusion 1112 is embedded in the limiting groove 122, and the first connecting end face 121 is located in the first connecting groove 111 and abuts against the bottom surface of the first connecting groove 111, through the limiting protrusion 1112 and the limiting groove 122, the first connecting rod 12 and the first pressing head 11.

[0066] In a preferred embodiment, the height of the limiting groove 122 in the Z direction is greater than the thickness of the limiting protrusion 1112 in the Z direction, thereby enabling the first pressing head 11 to rotate relative to the first connecting rod 12 .

[0067] In an optional embodiment, the welding strip flattening mechanism 100 also includes a second connecting rod 3 and a driving assembly 4, the driving end of the driving assembly 4 is rotatably connected to one end of the second connecting rod 3, and the other end of the second connecting rod 3 is abutted against the end of the first connecting rod 12 away from the first connecting end face 121, and the driving assembly 4 drives one end of the second connecting rod 3 to move along the Y direction, and the other end of the second connecting rod 3 can move along the Z direction to drive the first connecting rod 12.

[0068] like Figure 1As shown, the welding ribbon flattening mechanism 100 also includes a second connecting rod 3 and a driving assembly 4. The driving end of the driving assembly 4 is rotatably connected to one end of the second connecting rod 3. The driving assembly 4 drives one end of the second connecting rod 3 to move in the Y direction, and the other end of the second connecting rod 3 can rotate relative to the driving end of the driving assembly 4 around the axis in the X direction. In other words, the other end of the second connecting rod 3 can rotate along the axis of the rotating shaft between one end of the second connecting rod 3 and the driving end of the driving assembly 4, and the other end of the second connecting rod 3 abuts against the end of the first connecting rod 12 away from the first connecting end surface 121. When the driving assembly 4 drives one end of the second connecting rod 3 to move in the Y direction, the other end of the second connecting rod 3 can drive the first connecting rod 12 to move in the Z direction toward the second flattening assembly 2, thereby causing the first pressing head 11 and the second pressing head 21 to press the welding ribbon. This structure is simple and easy to install.

[0069] The driving component 4 may be an electric cylinder or a hydraulic cylinder.

[0070] like Figure 5 、 Figure 6 and Figure 7 As shown, according to the second aspect of the embodiment of the present application, a welding strip flattening device 200 is provided, comprising a plurality of the above-mentioned welding strip flattening mechanisms 100 and a mounting bracket 5, wherein the plurality of the welding strip flattening mechanisms 100 are all arranged on the mounting bracket 5.

[0071] In a specific embodiment, multiple ribbon flattening mechanisms 100 are spaced apart along the X-direction. Specifically, first flattening assemblies 1 are spaced apart along the X-direction, drive assemblies 4 are spaced apart along the X-direction, and second connecting rods 3 are spaced apart along the X-direction. Multiple ribbon flattening mechanisms 100 operate simultaneously, thereby improving the efficiency of pressing the ribbon.

[0072] In another specific embodiment, multiple first flattening components 1 are arranged at intervals along the X direction; multiple second connecting rods 3 are arranged at intervals along the X direction; multiple driving components 4 are divided into a first driving component group 6 and a second driving component group 7, and the first driving component group 6 and the second driving component group 7 are arranged along the Z direction. In the X direction, the driving component 4 of the second driving component group 7 is located between two adjacent driving components 4 of the first driving component group 6; two adjacent second connecting rods 3 are respectively connected to the driving component 4 of the first driving component group 6 and the driving component 4 of the second driving component group 7.

[0073] like Figure 1 、 Figure 5 and Figure 6 As shown, multiple first flattening components 1 are arranged at intervals along the X direction, multiple second connecting rods 3 are arranged at intervals along the X direction, and one second connecting rod 3 abuts against the corresponding first connecting rod 12.

[0074] like Figure 6 As shown, multiple drive components 4 are divided into a first drive component group 6 and a second drive component group 7, and the first drive component group 6 and the second drive component group 7 are spaced apart along the Z direction. In other words, the first drive component group 6 is located above the second drive component group 7 in the Z direction, and the number of drive components 4 in the first drive component group 6 will be one less than the number of drive components 4 in the second drive component group 7. If the number of drive components 4 in the first drive component group 6 is four, then the number of drive components 4 in the second drive component group 7 is three. In the X direction, the drive component 4 of the second drive component group 7 is located between two adjacent drive components 4 of the first drive component group 6; and two adjacent second connecting rods 3, one of which is connected to the driving end of the drive component 4 of the first drive component group 6, and the other is connected to the driving end of the drive component 4 of the second drive component group 7.

[0075] Since the length of the driving component 4 in the X direction is greater than the length of the second connecting rod 3 and the first flattening component 1 in the X direction, the multiple driving components 4 are divided into a first driving component group 6 and a second driving component group 7 arranged along the Z direction, thereby making the structure of the welding strip flattening device 200 more compact.

[0076] In an optional embodiment, the mounting bracket 5 includes a first end surface 51 and a second end surface 52, the first end surface 51 and the second end surface 52 are arranged opposite to each other along the X direction, and an accommodation space is defined between the first end surfaces 51 and the first end surfaces 51, and a plurality of second connecting rods 3 are spaced apart in the accommodation space along the X direction;

[0077] The welding strip flattening device 200 also includes a connecting shaft 8, which is rotatably connected to multiple second connecting rods 3 along the X direction. One end of the connecting shaft 8 is connected to the first end surface 51, and the other end of the connecting shaft 8 is connected to the second end surface 52.

[0078] like Figure 5 and Figure 6 As shown, the mounting bracket 5 includes a first end face 51 and a second end face 52. The first end face 51 and the second end face 52 are arranged opposite to each other along the X direction. There is an accommodating space between the first end face 51 and the second end face 52. A plurality of second connecting rods 3 are arranged in the accommodating space at intervals along the X direction.

[0079] To further illustrate, the welding strip flattening device 200 also includes a connecting shaft 8, the direction of the axis of the connecting shaft 8 is the same as the X direction, the connecting shaft 8 is rotatably connected to a plurality of second connecting rods 3, one end of the connecting shaft 8 is connected to the first end face 51, and the other end of the connecting shaft 8 is connected to the second end face 52; specifically, the mounting bracket 5 is provided with a first mounting hole on the first end face 51, and the mounting bracket 5 is provided with a second mounting hole on the second end face 52, one end of the connecting shaft 8 is connected to the first mounting hole, and the other end of the connecting shaft 8 is connected to the second mounting hole.

[0080] Further explanation: the connecting shaft 8 is located at one end of the second connecting rod 3 close to the first connecting rod 12. When the driving component 4 drives the other end of the second connecting rod 3 to move along the Y direction, the other end of the second connecting rod 3 rotates around the axis of the connecting shaft 8. The connecting shaft 8 can prevent the second connecting rod 3 from detaching from the end of the first connecting rod 12.

[0081] Preferably, a plurality of partitions 54 are spaced apart in the accommodating space along the X direction, and an accommodating groove 55 is formed between two adjacent partitions 54 . A second connecting rod 3 is placed in each accommodating groove 55 .

[0082] In an optional embodiment, the mounting bracket 5 is provided with a plurality of through holes 56 spaced apart along the X direction. One of the first connecting rods 12 is located within one of the through holes 56, and the sleeve 14 of the ribbon flattening mechanism 100 is embedded within the through hole 56. Therefore, the mounting bracket 5 also provides a mounting position for the sleeve 14 to facilitate compression of the elastic member 15. When the second connecting rod 3 moves upward under the action of the drive assembly 4, the elastic member 15 can rebound, thereby driving the first connecting rod 12 to return to its original position, that is, the first pressing head 11 moves away from the second pressing head 21.

[0083] According to a second aspect of an embodiment of the present application, a string welding machine is provided, comprising the above-mentioned welding ribbon flattening device 200.

[0084] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
