[0016] The specific embodiments of the present application will be further described in detail below in combination with the accompanying drawings, so that the technical scheme of the present application is easier to understand and master, and the protection scope of the present application is more clearly defined.

[0017] As Figure 1 and Figure 2The utility model discloses a busbar L type bending assembly, from the implementation structure of the overview, it is based on the straight rail 2 of gantry 1 is sequentially connected with first feeding mechanism 31, first material loading positioning mechanism 41, second feeding mechanism 32 and second material loading positioning mechanism 42. With first feeding mechanism 31 as an example, it is equipped with first driver 311 in the inside, and chuck 312 is connected with the output end of first driver, and the other feeding mechanism is same configuration. Again with first material loading positioning mechanism 41 as an example, it is equipped with the loading platform 411 of fixed attachment on the straight rail, and the side of the loading platform near opposite side edge 411a is equipped with the turnover pressure arm 412. The upward push folding mechanism 5 is equipped between two loading platforms, and is driven to lift along the opposite side edge of two loading platforms.

[0018] Here, two loading platforms are arranged side by side, aiming at realizing two L-shaped busbars to be formed simultaneously on both sides by cooperating with the upward push folding mechanism. Therefore, the two material loading positioning mechanisms and the upward push folding mechanism are fixed in position in the transverse direction. Corresponding to each loading platform, the feeding mechanism is configured in a complete set and does not interfere with each other, and is synchronized, which is beneficial to improve the efficiency of the busbar to be bent into position.

[0019] In combination Figure 2 And Figure 3 As shown from further details structure: the straight rail 2 is equipped with horizontal linear slide rail 21 on the side wall opposite to the upward push folding mechanism, and the two feeding mechanisms are sleeved on the linear slide rail and can be adjusted in transverse positioning. Since the position of the loading platform is fixed, the position of the feeding mechanism relative to the loading platform needs to have adjustable ability according to the size specification of the busbar to be formed. For this purpose, the first feeding mechanism is also equipped with a brake plug column 315 extending into the linear slide rail and a drive handle 316 for adjusting the tightness of the brake plug column, and the second feeding mechanism is also configured in the same structure.

[0020] In the above-mentioned first feeding mechanism, the chuck 312 is pivoted in the body seat 314 of the feeding mechanism, and the busbar 8a is inserted into the slot 313 on the bottom side of the chuck. The chuck 312 is driven by the first driver 311 to rotate within a limited range, and the busbar is pressed or released. In the pressed state, the busbar moves transversely with the feeding mechanism, cooperates with the turnover pressure arm to press the busbar on the loading platform, the chuck releases the pressure and resets backward, and then switches the pressing state of the chuck and the turnover pressure arm, realizes the step-by-step feeding. Preferably, the second material loading positioning mechanism 42 is exemplified, wherein the surface of the loading platform 421 is provided with two convex columns 422 distributed along the input direction of the busbar, the bottom of the loading platform is provided with a second driver 423, and the side of the loading platform is provided with a correcting push rod 424 connected to the output end of the second driver. The correcting push rod is driven to approach or separate from the two convex columns, so as to correct the busbar on the loading platform.

[0021] When referring to the function of the turnover pressing arm 413, the assembly structure is that the platform 411 is provided with a bypass support 412, and the bypass support is provided with a third driver 414 with an output end upward, one part of the turnover pressing arm 413 is pivoted to the bypass support 412, and the other part is connected to the output end of the third driver and extends upward to the platform surface, and another part is driven by the third driver to turn over and press the bus bar or turn over and release the displacement channel of the bus bar. It should be noted that, in order to show the structural details, part of the technical features is identified and described by two load positioning mechanisms, and in actual situation, the structures and functions of the two are the same.

[0022] In addition, the upward pushing and folding mechanism 5 is provided with a base 51 attached to the gantry 1, and the base 51 is provided with a fourth driver 52 and a plate-mounted push head 53 connected to the output end of the fourth driver. In the initial position state, the plate-mounted push head is positioned below the platform, so that the bus bar can be fed without interference; and in the state that the plate-mounted push head passes over the platform surface, the bus bar 8a is bent upward at a right angle in the gap formed between the plate-mounted push head and the opposite side edge 411a of the platform, and similarly, the bus bar 8b is bent upward at a right angle in the gap formed between the plate-mounted push head and the opposite side edge of the other platform 412. As can be seen from the figure, the bypass support occupies more space on the bottom side of the platform, especially on the outside of the opposite side edges. In order to avoid interference of the plate-mounted push head during lifting with the exposed part of the bypass support, the plate-mounted push head is formed in a continuous bending shape and non-contact wrapping part of the bypass support.

[0023] Due to the single direction of feeding, the right-angled bent parts of the two bus bars are slightly different. The left bus bar 8a in the figure is suspended outside after feeding, with the rear section being pressed on the platform; and the right bus bar 8b in the figure is suspended outside after feeding, with the front section being pressed on the platform. After the plate-mounted push head is lifted, the front section of the left bus bar 8a and the rear section of the right bus bar 8b will be bent upward by 90 degrees.

[0024] As can be seen from the above introduction and embodiment details of the bus bar L-shaped bending assembly of the utility model, the present scheme has substantial characteristics and progressiveness: by using the bending assembly, a pair of bus bars of a preset length can be automatically bent in an L shape as a mirror image in the process of attaching the bus bars, which facilitates quick connection of multiple bus bars to the same current path or junction box in the subsequent process; and manual intervention is not required in the operation, which greatly improves the production efficiency.

[0025] In addition to the above embodiments, the utility model can also have other implementation manners, and any technical scheme formed by equivalent replacement or equivalent transformation falls within the scope of the utility model claimed.
