Description

Technical Field

[0001] This utility model belongs to the field of copper busbar assembly technology, and specifically relates to a copper busbar sealing ring assembly device. Background Technology

[0002] In the electronic control system of new energy vehicles, the three-phase copper busbar, as a key component connected to the motor, often has airtight requirements. Currently, there are two main sealing methods used for this type of product: glue potting and the assembly of sealing rings.

[0003] In the existing technology, the installation of sealing rings on three-phase copper busbars is generally done manually. Workers need to open the sealing rings by hand and then install them into the sealing grooves of the three-phase copper busbars. The disadvantages are: when the workers are not skilled enough, it will affect the efficiency of the installation; manually opening the sealing rings is not easy, time-consuming and laborious, and it is also easy to damage the sealing rings due to improper force, thereby affecting the sealing quality of the three-phase copper busbars. Utility Model Content

[0004] The purpose of this invention is to provide a copper busbar sealing ring assembly device that can avoid human damage to the sealing ring during manual assembly and the sealing risks caused by the instability of the manual assembly process.

[0005] The purpose of this utility model is achieved as follows: A copper busbar sealing ring assembly device includes: a workbench; a copper busbar positioning mechanism disposed on the workbench for placing a three-phase copper busbar; a plurality of positioning posts at the same horizontal height for placing the sealing ring; a horizontal expansion mechanism disposed on the workbench for driving the plurality of positioning posts to move outward a specified distance or return inward simultaneously, so as to transform the sealing ring in its natural state into an expanded state; a push plate located below the sealing ring; and a vertical lifting mechanism disposed on the workbench for driving the push plate to move upward or return downward, so as to push the sealing ring in the expanded state away from the positioning posts onto the three-phase copper busbar.

[0006] In use, the sealing ring in its natural state is fitted onto the outside of several positioning posts. A horizontal expansion mechanism drives the positioning posts to move outwards simultaneously by a certain distance, thus expanding the sealing ring outwards according to a set ratio. The three-phase copper busbar is then placed on the busbar positioning mechanism. A vertical lifting mechanism drives a push plate to move upwards by a certain distance, thereby pushing the expanded sealing ring upwards a certain distance. The sealing ring, detached from the positioning posts, retracts onto the three-phase copper busbar, completing the assembly. Finally, the three-phase copper busbar is removed. Compared with existing technologies, the advantages of this invention are: using this device to assemble the sealing ring results in a higher efficiency than traditional manual assembly; the degree of sealing ring expansion is controllable, avoiding human damage to the sealing ring during manual assembly and the sealing risks caused by the instability of the manual assembly process, thus ensuring the sealing quality of the three-phase copper busbar.

[0008] As a further improvement of this utility model, the horizontal expansion mechanism includes several horizontal cylinders that are arranged one-to-one with the positioning columns. The cylinder body of the horizontal cylinder is mounted on the upper side of the worktable through a fixed seat, and the end of its piston rod is connected to the positioning column through a connecting block. A linear module is arranged between the connecting block and the worktable.

[0009] As a further improvement of this utility model, the linear module includes a slider and a linear guide rail. The upper side of the slider is fixedly connected to the connecting block, and the lower side is slidably connected to the linear guide rail.

[0011] As a further improvement of this utility model, the vertical lifting mechanism includes a vertical cylinder, the cylinder body of which is located on the lower side of the worktable, and a lifting plate is provided at the end of its piston rod. The lifting plate is connected to the push plate through four guide rods arranged in a rectangular shape. A linear bearing is sleeved on the guide rods, and the linear bearing is fixed on the worktable.

[0012] As a further improvement of this utility model, a limiting step is provided at the top of the positioning column, and the limiting step abuts against the inner wall of the sealing ring.

[0013] As a further improvement of this utility model, it also includes a copper busbar detection mechanism, which includes a laser sensor, and the laser sensor is mounted on the upper side of the workbench via a bracket.

[0020] like Figure 1-4 The diagram shows a copper busbar sealing ring assembly device, comprising: a workbench 1; a copper busbar positioning mechanism 2, mounted on the workbench 1, for placing a three-phase copper busbar 3; six positioning posts 4 at the same horizontal height for placing a sealing ring 5; a horizontal expansion mechanism 6, mounted on the workbench 1, for driving the six positioning posts 4 to move outward a specified distance or return inward simultaneously, so as to convert the sealing ring 5 in its natural state into an expanded state. Preferably, a limiting step 401 is provided at the top of the positioning posts 4, and the limiting step 401 abuts against the inner wall of the sealing ring 5; a push plate 7, located below the sealing ring 5; a vertical lifting mechanism 8, mounted on the workbench 1, for driving the push plate 7 to move upward or return downward, so as to push the sealing ring 5 in the expanded state away from the positioning posts 4 onto the sealing groove of the three-phase copper busbar 3; and a copper busbar detection mechanism 9, which includes a laser sensor 901, mounted on the workbench 1 via a bracket 902.

[0021] In this embodiment, the copper busbar positioning mechanism 2 includes a positioning plate 201, which is supported on the upper side of the workbench 1 by four rectangularly distributed columns 202. Positioning slots 203 are provided on the positioning plate 201 corresponding to the three-phase copper busbars 3. The horizontal expansion mechanism 6 includes six horizontal cylinders 601, each corresponding to one of the positioning columns 4. The cylinder body of each horizontal cylinder 601 is mounted on the upper side of the workbench 1 via a fixed seat 602. The end of its piston rod is connected to the corresponding positioning column 4 via a connecting block 603. A linear module is provided between the corresponding connecting block 603 and the workbench 1. Specifically, the linear module includes a slider 604 and a linear guide rail 605. The upper side of the slider 604 is fixedly connected to the connecting block 603, and the lower side is slidably connected to the linear guide rail 605. The bottom is fixedly connected to the upper side of the workbench 1; the push plate 7 has a clearance groove 701 for the passage of the three-phase copper busbar 3, and the clearance groove 701 has a limit groove 702 for each of the six positioning columns 4; the vertical lifting mechanism 8 includes a vertical cylinder 801, the cylinder body of the vertical cylinder 801 is located on the lower side of the workbench 1, and the piston rod end of the cylinder is provided with a lifting plate 802. The lifting plate 802 is connected to the push plate 7 through four rectangularly distributed guide rods 803. The guide rods 803 are fitted with linear bearings 804, and the linear bearings 804 are fixed on the workbench 1; the workbench 1 includes a support frame, the top of the support frame is provided with a platform 101, and the surrounding area is provided with a protective shell 102.

[0022] In use, the sealing ring 5 in its natural state is fitted onto the outside of the six limiting steps 401. Pressing the start button 10 activates the six horizontal cylinders 601 simultaneously, causing the piston rods to retract and move the six positioning pins 4 outwards a certain distance, thus expanding the sealing ring 5 outwards according to a set ratio. Then, the three-phase copper busbar 3 is placed on the positioning plate 201, with its bottom passing through the clearance groove 701. Pressing the start button 21 activates the vertical cylinder 801, causing its piston rod to retract and move the push plate 7 upwards a certain distance. Under the push of the push plate 7, the expanded sealing ring 5 moves upwards a certain distance until it detaches from the positioning pins 4. The sealing ring 5, no longer secured by the limiting steps 401, retracts onto the three-phase copper busbar 3, thus completing the assembly. Finally, the three-phase copper busbar 3 is removed. Pressing the start button 10 and start button 21 again resets all cylinders, allowing for the next assembly. The advantages of this utility model are: it uses a cylinder as the driving component, which has a fast response and is easy to operate, and can realize the rapid assembly of the sealing ring 5; the limiting groove 702 can limit the displacement of the positioning column 4, avoid excessive displacement and damage to the sealing ring 5, and ensure its sealing performance; the laser sensor 901 can detect whether the copper busbar is in place, and if an emergency occurs during the assembly process, the operation of all mechanisms can be stopped by the emergency stop button to ensure personal and product safety.
