Description

Technical Field

[0001] This invention relates to the field of tooling for new energy vehicle manufacturing, and specifically to a positioning mechanism for installing soft copper busbars. Background Technology

[0002] Figure 1 It is a controller used in new energy vehicles, which has a first soft copper busbar 100 and a second soft copper busbar 200. Figure 2 This is a split diagram of the controller. Both the first flexible copper busbar 100 and the second flexible copper busbar 200 have bolt mounting holes. One end of the first flexible copper busbar is fastened to the stud 400 of the housing by a nut 500, and the other end is fastened to the screw hole 700 of the housing by a bolt 600. Both ends of the second flexible copper busbar are fastened to the screw hole 700 of the housing by bolts 600.

[0003] The existing installation method involves manually observing whether the holes are aligned and judging whether the two soft copper busbars are installed in place. Because the soft copper busbars are prone to deformation, it is often necessary to pull them while tightening the bolts to install them. This is time-consuming, labor-intensive, and inefficient, and problems such as misalignment and deformation may occur at any time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a positioning mechanism for installing flexible copper busbars, thereby improving the installation efficiency and yield of flexible copper busbars.

The driving mechanism is used to drive the first positioning block and the second positioning block to move back and forth in the left-right direction and the up-down direction. The first and second positioning blocks work together to position the second soft copper busbar in all directions. The movable block can move back and forth in the left and right directions. The movable block and the first positioning block work together to position the first soft copper busbar in the front, back, left and right directions.

[0006] Furthermore, the first positioning block is provided with a first bayonet, which provides front, back and right positioning for the first flexible copper busbar. The movable block is located to the left of the first bayonet for positioning the left side of the first flexible copper busbar.

[0007] Furthermore, the bottom right side of the movable block has a right-angle notch, and the top right of the right-angle notch has a chamfer.

[0008] Furthermore, the first positioning block is provided with a second bayonet, and the second positioning block is provided with a third bayonet.

The second bayonet provides three-way positioning for the second soft copper busbar in the left, front, and back directions, and the third bayonet provides three-way positioning for the second soft copper busbar in the right, front, and back directions.

[0009] Furthermore, the movable block is connected to a first cylinder, which can drive the movable block to move in the left and right direction. The first cylinder is fixed on the bracket. The drive mechanism includes a second cylinder and a third cylinder. The second cylinder is fixed on the bracket, and the third cylinder is fixedly connected to the second cylinder through a first connecting block.

Detailed Implementation

[0015] like Figures 3 to 8 As shown, this embodiment discloses a positioning mechanism for installing soft copper busbars, which is used to assist in fixing the soft copper busbars to the housing 300 of the controller. There are two soft copper busbars, namely a first soft copper busbar 100 and a second soft copper busbar 200.

[0016] The positioning mechanism includes a bracket on which a positioning fixture 1, a movable block 2 and a positioning component are mounted. The positioning fixture 1 is used to position the housing 300. The positioning component includes a first positioning block 4, a second positioning block 5, and a driving mechanism. The driving mechanism is used to drive the first positioning block 4 and the second positioning block 5 to move back and forth in the left-right direction and the up-down direction. The first positioning block 4 and the second positioning block 5 work together to position the second soft copper busbar 200 in all directions. The movable block 2 can move back and forth in the left and right directions; the movable block 2 and the first positioning block 4 work together to position the first soft copper busbar 100 in the front, back, left and right directions.

[0017] The positioning mechanism described in this embodiment, through the cooperation of the movable block 2 and the positioning component, can quickly complete the positioning of the first soft copper busbar 100 and the second soft copper busbar 200 around their perimeter. The subsequent bolt tightening process can be carried out by automated equipment, improving the automation level of the controller manufacturing process. This positioning mechanism is reliable in structure, simple and convenient, saves time and labor, and has low requirements for personnel operation.

[0018] In the specific structure, the first positioning block 4 is provided with a first latch 41 and a second latch 42, and the second positioning block 5 is provided with a third latch 43. The part of the first flexible copper busbar 100 to be fixed (with bolt mounting holes) is placed between the movable block 2 and the first latch 41. The first latch 41 provides three-way positioning for the first flexible copper busbar 100 in the front, back, and right directions. The movable block 2 is located to the left of the first latch 41 to position the first flexible copper busbar 100 on the left side. The movable block 2 cooperates with the first latch 41 to restrict the movement of the first flexible copper busbar 100 in the left-right direction, and the second latch 42 restricts the front-back movement of the first flexible copper busbar 100 through two opposing side walls.

[0019] The second latch 42 and the third latch 43 are set at 90°. The part of the second flexible copper busbar 200 to be fixed (with bolt mounting holes) is placed between the second latch 42 and the third latch 43. The second latch 42 provides three-way positioning for the second flexible copper busbar 200 in the left, front, and back directions, while the third latch 43 provides three-way positioning for the second flexible copper busbar 200 in the right, front, and back directions. The second latch 42 restricts the front-back movement of the second flexible copper busbar 200 through its two opposing front and rear side walls, while the third latch 43 restricts the left and right movement of the second flexible copper busbar 200 through its two opposing left and right side walls.

[0020] Preferably, the right end of the movable block 2 has a right-angle notch 21 on its bottom surface, and the right top of the right-angle notch 21 has a chamfer 22. After the driving mechanism drives the first positioning block 4 and the second positioning block 5 to the predetermined position, the first soft copper busbar 100 and the second soft copper busbar 200 are placed on the housing 300 at the position to be fixed. At this time, the second soft copper busbar 200 is positioned by the action of the second latch 42 and the third latch 43. Then, the movable block 2 is moved to the left side of the first soft copper busbar 100, and the left side wall of the right-angle notch 21 pushes the first soft copper busbar 100 to the right until it contacts the front, rear, and right side walls of the first latch 41. The top surface of the right-angle notch 21 abuts against the top surface of the first soft copper busbar 100 to press the first soft copper busbar 100. The chamfer 22 facilitates the insertion of the first soft copper busbar 100 into the right-angle notch 21 and avoids impact damage to the first soft copper busbar 100 caused by the movable block 2. The movable block 2 not only works with the first positioning block 4 to position the first soft copper busbar 100, but also has the function of pressing down the first soft copper busbar 100 to prevent it from shifting during the bolt tightening process.

[0021] The movable block 2 is connected to a first cylinder 6, which drives the movable block 2 to move in the left-right direction. The first cylinder 6 is fixed on the bracket. The driving mechanism includes a second cylinder 7 and a third cylinder 8. The second cylinder 7 is fixed on the bracket, and the third cylinder 8 is fixedly connected to the second cylinder 7 through a first connecting block 9. The first positioning block 4 and the second positioning block 5 are fixedly connected to the third cylinder 8 through a second connecting block 10. The second cylinder 7 drives the third cylinder 8 to move in the left-right direction, and the third cylinder 8 drives the first positioning block 4 and the second positioning block 5 to move in the up-down direction. The positioning mechanism for installing soft copper busbars provided in this embodiment provides simple power through three cylinders, which can quickly and reliably perform positioning, clamping, and other actions on the first soft copper busbar 100 and the second soft copper busbar 200. The cylinders described in this embodiment can also be replaced by hydraulic cylinders, linear modules, or other mechanisms that perform linear motion.

[0022] Preferably, cylinder sensors are installed on the first cylinder 6, the second cylinder 7, and the third cylinder 8. Cylinder sensors are existing technology and are key components in industrial automation systems used to detect the position and state of pneumatic cylinder pistons, enabling precise monitoring and control of the cylinder piston position. By using cylinder sensors to determine whether the first cylinder 6, the second cylinder 7, and the third cylinder 8 have reached their designated positions, detailed visual inspection is unnecessary. This ensures that the movable block 2, the first positioning block 4, and the second positioning block 5 are accurately moved to their predetermined positions, improving positioning accuracy and preventing the first soft copper busbar 100 and the second soft copper busbar 200 from becoming misaligned.

[0023] The top surface of the positioning fixture 1 is provided with a positioning groove 11, and multiple positioning pins 12 are installed on the positioning fixture 1. When the housing 300 is placed in the positioning groove 11, the bottom surface of the housing 300 contacts the bottom of the positioning groove 11. The positioning fixture 1 cooperates with each positioning pin 12 to restrict the housing 300 in four directions (front, back, left, and right) and prevent the housing 300 from moving along the horizontal plane.

[0024] Specifically, the positioning pins 12 are distributed on the left and right sides of the positioning groove 11. Each side of the positioning groove 11 is provided with multiple positioning pins 12. When the housing 300 is placed in the positioning groove 11, the groove walls at the front and rear ends of the positioning groove 11 contact the front and rear ends of the housing 300 respectively to restrict the front and rear movement of the housing 300, and the left and right sides of the housing 300 contact the positioning pins 12 to restrict the left and right movement of the housing 300.

[0025] The bottom surface of the controller is uneven, and the shape of the controller's perimeter is irregular. If the housing 300 is positioned solely by the positioning groove 11, not only would the positioning groove 11 need to be designed to resemble the shape of the controller, increasing the processing difficulty of the positioning groove 11, but the depth of the positioning groove 11 would also need to be increased, resulting in an increase in the thickness of the positioning fixture 1 and increasing material costs. In this embodiment, the housing 300 is positioned using both the positioning pin 12 and the positioning groove 11. The top surface of the positioning fixture 1 is provided with multiple insertion holes for installing the positioning pin 12 one by one. The axial length of the positioning pin 12 increases the vertical constraint on the housing 300, thereby reducing the vertical sway of the housing 300. This reduces the depth requirement of the positioning groove 11, and thus reduces the thickness of the positioning fixture 1, saving costs.

[0026] Preferably, the top of the positioning pin 12 is tapered to guide the housing 300 into the positioning groove 11, facilitating the placement of the housing 300 into the positioning groove 11 from top to bottom. Alternatively, the positioning pin 12 may have its top edge be sloped near the housing 300 for guiding the housing 300.

[0027] The bracket in this embodiment includes a base plate 13 and a top plate 14. The top plate 14 and the base plate 13 are connected by multiple columns 15. The positioning fixture 1 is installed on the top plate 14. The second cylinder 7 is fixedly installed on the bottom surface of the top plate 14. The first cylinder 6 is installed on the left side of the top plate 14 through the third connecting block 3 22. The third cylinder 8 is located on the right side of the top plate 14.

[0028] In use, the first cylinder 6 drives the movable block 2 to move to the left, and the second cylinder 7 drives the first positioning block 4 and the second positioning block 5 to move to the right, thereby completely exposing the positioning groove 11. Then, the controller housing 300 is placed in the positioning groove 11. Next, the second cylinder 7 drives the first positioning block 4 and the second positioning block 5 to move above the controller housing 300. The third cylinder 8 drives the first positioning block 4 and the second positioning block 5 to move down to be close to or in contact with the housing 300. Then, the first soft copper busbar 100 and the second soft copper busbar 200 are placed on the housing 300. Finally, the first cylinder 6 drives the movable block 2 to move to the right, and the movable block 2 pushes the first soft copper busbar 100 to the right and presses it tightly.

[0029] The above description is only a preferred embodiment of the present invention. It should be understood that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
