[0035] In order to make the person skilled in the art better understand the utility model scheme, the utility model is further explained in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the scope of protection of the utility model.

[0036] The core of the utility model is to provide a kind of new energy vehicle multi-bending female lead production equipment, and the partial structure schematic diagram of one of its specific embodiments is as shown in Figure 1 to Figure 2, called specific embodiment one, for producing the new energy vehicle multi-bending female circuit as described above any one, including single-sided baffle 500, fixed base plate 100 and extrusion contact 200;

[0037] The fixed base plate 100 includes positioning fixing piece 110, molding pulling head 120 and pulling track 130;

[0038] The positioning fixing piece 110 is used to position and fix base material wire 300;

[0039] The molding pulling head 120 is arranged in the pulling track 130, and can reciprocate in the pulling track 130;

[0040] The starting position of multiple molding pulling heads 120 is alternatively arranged on the two sides of the base material wire 300 along the extension direction of the base material wire 300;The movement direction of adjacent molding pulling heads 120 from the starting position is opposite, and the movement direction is all intersected with the base material wire 300;The molding pulling head 120 movement drives the base material wire 300 to form multiple bending and circuitous sections;

[0041] The extrusion contact 200 is used to press the base material wire 300 forming the bending and circuitous section from two sides of the single-sided baffle 500, so that the wire section between the bending and circuitous section forms mutually adhering and parallel straight line section;

[0042] The single-sided baffle 500 includes cushion block 510, and the cushion block 510 is in contact with the straight line section in the process of pressing the base material wire 300, and the contact surface of the cushion block 510 and the straight line section is all located in the first plane;The first plane is perpendicular to the pressing direction of the extrusion contact 200.

[0043] As a preferred embodiment, a height limiting plate is further included, which forms a working cavity with the fixed base plate 100, and the substrate wire 300 is arranged in the working cavity;

[0044] The distance between the height limiting plate and the fixed base plate 100 is consistent with the diameter of the substrate wire 300.

[0045] The specific embodiment ensures that the straight sections of the substrate wire 300 under pressure are always kept flat during the pressing process by the first plane, greatly avoiding the generation of local stress concentration in the substrate wire 300 during the pressing process between the extrusion contact 200 and the single-sided baffle 500, and finally leading to the inconsistency between the obtained substrate wire 300 shape and the preset, even the local damage due to stress concentration, greatly improving the standardization degree of the shape of the substrate wire 300 after pressing, and improving the yield of finished products.

[0046] In the specific embodiment, the thickness of the working cavity, that is, the distance between the height limiting plate and the fixed base plate 100, is consistent with the diameter of the substrate wire 300, that is, the substrate wire 300 is clamped by the fixed base plate 100 and the height limiting plate, and when the substrate wire 300 is pressed, the extrusion contact 200 needs to be inserted into the working cavity to ensure that the substrate wire 300 is always in the same plane during the compaction process, avoiding the misalignment of different straight sections in different planes, and the subsequent processing difficulty. Of course, the distance between the height limiting plate and the fixed base plate 100 is consistent with the diameter of the substrate wire 300, which means that the two can be exactly the same, or there can be a certain error, and the specific value of the error can be selected according to the actual situation.

[0047] Further, all the pulling tracks 130 are parallel to each other. Referring to FIGS. 1-3, all the pulling tracks 130 in the above three figures are parallel to each other, which facilitates the subsequent pressing of the substrate wire 300 by the extrusion contact 200 and improves the production efficiency. In addition, FIG. 1 is a structure schematic view in which the substrate wire 300 is positioned and fixed, and the plastic pulling head 120 is located at the starting position; FIG. 2 is a structure schematic view after the plastic pulling head 120 starts to move along the pulling track 130 and pulls the substrate wire 300.

[0048] Further, a chuck 400 and a welding assembly are further included;

[0051] As shown in FIG. 3, the chuck 400 is directly attached to the edge of the fixed substrate 100, and the side surface of the chuck 400 in the thickness direction can directly serve as the single-sided baffle 500 opposite to the extrusion contact 200, assisting in the pressing of the substrate wire 300 during the pressing of the substrate wire 300 by the extrusion contact 200, thereby simplifying the structure of the production equipment of the multi-bending busbar wire of the new energy vehicle and reducing the equipment cost.

[0052] As another preferred embodiment, a hot press plate is further included.

[0053] The surface of the hot press plate includes a groove corresponding to the shape of the multi-bending busbar wire 10, for hot pressing and shaping the substrate wire 300 subjected to pulling and pressing.

[0054] The state sensor 20 is connected to the signal transmission bus 30 through the multi-bending busbar wire 10, and transmits signals to the signal transmission bus 30. In individual application scenarios, such as new energy vehicles, there is a certain gap between the signal transmission bus 30 and the battery of the vehicle. The wire or metal sheet is arranged at this position, and the space at this position is extremely limited, and reasonable layout is required to not affect other components.

[0055] Therefore, in the specific embodiment, the substrate wire 300 subjected to pulling and pressing (i.e., the multi-bending busbar wire 10 in the foregoing) is further hot pressed and shaped by the hot press plate. On the one hand, the shape of the wire is kept regular, facilitating standardized mass production in subsequent processes. On the other hand, the multi-bending busbar wire 10 is strictly shaped into a planar plate structure by hot pressing, facilitating the embedding of the multi-bending busbar circuit of the new energy vehicle into the gap around the battery during installation, and reducing the installation difficulty. Of course, if the bonding between adjacent straight sections of the multi-bending busbar wire 10 needs to be performed by heat treatment, it can also be completed synchronously in the hot pressing process.

[0056] The distance between the positioning fixing member 110 and the extrusion contact 200 is greater than the distance between any of the pulling tracks 130 and the extrusion contact 200.

[0057] The first plane is located between the positioning fixing member 110 and the pulling track 130 closest to the positioning fixing member 110.

[0058] In the specific embodiment, the first plane is arranged between the positioning fixture 110 and the pulling track 130 closest to the positioning fixture 110, so as to avoid the positioning fixture 110 from becoming a stress concentration point when the base material wire 300 is pressed, and further improve the bending effect of the base material wire 300 after being pressed, and improve the yield of the finished product.

[0059] As a specific embodiment, the dispensing device is further included.

[0060] The dispensing device is used to add adhesive between the straight line segments, so as to bond adjacent straight line segments.

[0061] That is, in the specific embodiment, the dispensing device is used to bond adjacent straight line segments, and the dispensing device has high bonding efficiency, can greatly improve the production efficiency of the new energy vehicle multi-bending busbar circuit, is easy to popularize and expand the production scale, and has stronger universality.

[0062] Further, the extrusion contact 200 is a rod-shaped contact.

[0063] In the preferred embodiment, the rod-shaped contact is used, which occupies less space and is more flexible to assemble while being able to press the base material wire 300, and increases the universality of the equipment.

[0064] Further, the production equipment of the new energy vehicle multi-bending busbar wire includes a plurality of rod-shaped contacts.

[0065] A plurality of rod-shaped contacts are arranged, which can simultaneously press a plurality of regions of the straight line segment, so as to ensure the uniformity of the stress of the straight line segment during the pressing process, thereby improving the uniformity and meeting the expectation of the bonding force of each position of the straight line segment, and improving the working stability of the finished product.

[0066] Further, a plurality of contact drivers are included.

[0067] The plurality of contact drivers correspondingly drive the plurality of rod-shaped contacts.

[0068] In other words, the rod-shaped contacts in the preferred embodiment are no longer controlled by one driver, are pressed together when pressed, and are withdrawn together when the pressing is ended, but different contact drivers are used to control different rod-shaped contacts, which provides more choices for the processing of the base material wire 300, and greatly improves the universality of the equipment.

[0069] The utility model provides a new energy vehicle multi -bending female row wire's production facility, including single side baffle 500, fixed base plate 100 and extrusion contact 200, the fixed base plate 100 includes positioning fixed part 110, plastic type pulling head 120 and pulling track 130, positioning fixed part 110 is used for positioning fixed base material wire 300, plastic type pulling head 120 is set up in pulling track 130, and it can reciprocate in pulling track 130, the starting position of multiple plastic type pulling head 120, along the extension direction of base material wire 300 is alternately arranged in the both sides of base material wire 300, and the movement direction of adjacent plastic type pulling head 120 starts from the starting position is opposite, and the movement direction all is with base material wire 300 intersection, plastic type pulling head 120 movement drives base material wire 300 forms multiple bending circuitous section, extrusion contact 200 is used for with single side baffle 500 from both sides to the base material wire 300 of forming bending circuitous section pressure, makes the wire segment fall between bending circuitous section forms mutually adhering and parallel straight line segment, single side baffle 500 includes cushion block 510, the cushion block 510 is adhered contact with straight line segment in the process of pressure to base material wire 300, and the contact surface of cushion block 510 and straight line segment all is located first plane, first plane and the pressure direction of extrusion contact 200 are perpendicular, the new energy vehicle multi -bending female row wire's production facility can through the plastic type pulling head 120 on fixed base plate 100 fastly pull base material wire 300 to approach predetermined shape, further compacts, bonding again through extrusion contact 200, can obtain the multiple bending folding wire 10, when the production speed of multiple bending folding wire 10 is improved, the standardization degree of multiple bending folding wire 10 is greatly improved, provides the basis for subsequent mass production.
