Description

Technical Field

[0001] This utility model relates to the field of weld grinding technology, specifically to a battery box weld grinding system. Background Technology

[0002] In the manufacturing process of new energy battery boxes, welding is often used to fix and install various components. After welding is completed, the weld seams usually need to be ground to remove excess solder in order to ensure the overall aesthetics of the battery box.

[0003] In existing technologies, manual polishing is often carried out by operators holding hand grinders. This not only fails to guarantee the overall flatness of the battery box after polishing, but also results in slow overall polishing efficiency and high labor costs. Utility Model Content

[0004] In view of this, the present invention provides a battery box weld grinding system that can ensure product consistency while also speeding up grinding efficiency and reducing labor costs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A battery box weld grinding system is characterized by comprising a positioning platform, a robotic arm, and a grinding device. The positioning platform has a working area on its top for fixing and installing the battery box. The robotic arm is disposed at one end of the positioning platform and is a multi-degree-of-freedom robotic arm whose range of motion covers the working area. The grinding device is fixedly disposed at the front end of the robotic arm and has a rotatable flap wheel. The flap wheel is used to grind the weld seam of the battery box and drives the robotic arm to move the flap wheel above the working area.

[0007] By adopting the above structure, the blade wheel controlled by the robotic arm is used to grind the weld seams of the battery box, realizing mechanized operation, ensuring product consistency, and also speeding up the grinding efficiency.

[0008] Preferably, the system also includes a tool magazine, which is located at the same end of the positioning platform as the robotic arm. The tool magazine holds the flap wheel, and driving the robotic arm to rotate to the side where the tool magazine is located allows the flap wheel to be mounted on the grinding device. This structure enables the flap wheel to be replaced, ensuring overall processing efficiency.

[0009] Preferably, the tool magazine is equipped with positioning jaws, and each positioning jaw is fixedly fitted with the flap wheel. This structure allows the robotic arm to directly control the grinding device by installing the positioning jaws.

[0010] Preferably, the grinding device includes a drive motor fixedly mounted at the end of the robotic arm and a rotating shaft powered by the drive motor, with the flap wheel fixedly connected to one end of the rotating shaft. Using this structure, the drive motor drives the rotating shaft to rotate, which in turn drives the flap wheel to rotate, thereby achieving the grinding of the weld seams of the battery casing.

[0011] Preferably, the flapper wheel includes a grinding head and a grinding head mounting shaft. The grinding head mounting shaft is vertically mounted within the positioning jaws, and the middle portion of the grinding head is fixedly fitted onto the lower end of the grinding head mounting shaft. With this structure, the mounting shaft facilitates both fixing the flapper wheel to the positioning jaws and fixing it to the rotating shaft.

[0012] Preferably, the grinding head includes a central disk and blades arranged in a circumferential array around the central disk, each blade being radially inclined relative to the central disk. With this structure, the rotating blades can be used to grind the weld seams of the battery casing.

[0013] Preferably, each blade is an arc-shaped blade. This structure facilitates the grinding of the weld seam.

[0014] Preferably, a rotary table is fixedly mounted on one side of the positioning platform, and the robotic arm is rotatably mounted on top of the rotary table. This structure facilitates the robotic arm's rotation to the tool magazine for changing the flap wheels.

[0015] Preferably, the positioning platform has a rotating base, with a working area located on the upper side of each end of the rotating base, and a partition between the two working areas. This structure allows for simultaneous grinding of the weld seams of two battery boxes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The battery box weld grinding system provided by this utility model uses a robotic arm to control the flap wheel to grind the battery box weld, realizing mechanized operation, ensuring product consistency, and also speeding up the grinding efficiency.

[0018] 2. The tool magazine allows for timely replacement of the flaps, thereby ensuring overall processing efficiency. Attached Figure Description

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figure 1 As shown, a battery box weld grinding system includes a positioning platform 1, a robotic arm 2, and a grinding device 3. The top of the positioning platform 1 is formed with a working area 1b for fixing and installing the battery box 7. The robotic arm 2 is installed at one end of the positioning platform 1. In this embodiment, the robotic arm 2 is a multi-degree-of-freedom robotic arm, and its range of motion covers the working area 1b. The grinding device 3 is fixedly installed at the front end of the robotic arm 2, and the grinding device 3 has a rotatable flap wheel 3a. The flap wheel 3a is used to grind the weld seam on the surface of the battery box 7. Driving the robotic arm 2 can drive the flap wheel 3a to move above the working area 1b.

[0028] With this design, the weld seams on the surface of the battery box 7 can be mechanically ground by the movement of the flap wheel 3a driven by the robotic arm 2, which greatly speeds up the grinding efficiency and also ensures the consistency of the product after grinding.

[0029] like Figure 1 and Figure 2 As shown, the battery box weld grinding system also includes a tool magazine 4. The tool magazine 4 and the robotic arm 2 are located on the same side of the positioning platform 1. The tool magazine 4 is equipped with a flap wheel 3a. After the robotic arm 2 is driven to rotate to the side where the tool magazine 4 is located, the flap wheel 3a can be replaced.

[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the tool magazine 4 has positioning claws 5 arranged in an array, and each positioning claw 5 is fixedly mounted with a flap wheel 3a. In this embodiment, the flap wheel 3a includes a grinding head 3a1 and a grinding head mounting shaft 3a2, wherein the grinding head mounting shaft 3a2 is vertically mounted on the positioning claw 5, and the middle part of the grinding head 3a1 is fixedly fitted onto the lower end of the grinding head mounting shaft 3a2.

[0031] Furthermore, such as Figure 6 As shown, the grinding head 3a1 includes a central disk b and blades a arranged in a circumferential array around the central disk b. Each blade a is radially inclined relative to the central disk b. In this embodiment, the blade a is an arc-shaped blade. One end of the grinding head mounting shaft 3a2 is fixedly connected to the central disk b. In the actual grinding process, the grinding is mainly achieved by the high-speed rotating blades a contacting the weld seam on the surface of the battery box 7.

[0032] like Figure 4 and Figure 5 As shown, the grinding device 3 includes a drive motor 3b fixedly mounted at the end of the robotic arm 2 and a rotating shaft 3c that is powered by the drive motor 3b. The flap wheel 3a is fixedly mounted at one end of the rotating shaft 3c. In this embodiment, the flap wheel 3a is fixedly connected to one end of the rotating shaft 3c by a snap-fit ​​mechanism.

[0033] In this embodiment, the drive motor 3b is fixedly mounted on the mounting base 2a. The mounting base 2a is rotatably mounted on the end of the robotic arm 2, which allows for adjustment of the grinding angle.

[0034] For example Figure 1 As shown, a rotary worktable 6 is fixedly installed on one side of the positioning platform 1, and the robotic arm 2 is rotatably mounted on the top of the rotary worktable 6. This design enables the robotic arm 2 to rotate to the tool magazine 4, thereby facilitating the replacement of the flap wheel 3a.

[0035] In this embodiment, the installation and replacement of the flap wheel 3a are achieved through automatic replacement. Specifically, the worktable 6 is rotated to move the robotic arm 2 to the tool magazine 4, and the mounting base 2a is rotated to bring the rotating shaft 3c into a vertical position and align it with the grinding head mounting shaft 3a2. Finally, the robotic arm 2 moves downward, causing the grinding head mounting shaft 3a2 to be engaged with the end of the rotating shaft 3c, thus completing the installation of the flap wheel 3a. In this embodiment, a locking device can be provided between the rotating shaft 3c and the grinding head mounting shaft 3a2 to facilitate their fixation and separation. When the flap wheel 3a needs to be replaced, the locking device only needs to be controlled to separate the two. Alternatively, the grinding head mounting shaft 3a2 can be engaged in the positioning jaw 5 by the robotic arm 2 and then pulled upward.

[0036] like Figure 7 As shown, a cylinder assembly 1a is fixedly installed on the top circumferentially of the positioning platform 1. In this embodiment, the battery box 7 is fixedly installed on the top of the positioning platform 1 by the cylinder assembly 1a.

[0037] Again Figure 1As shown, the positioning platform 1 has a rotating base 1c, and a working area 1b is provided on the upper side of each end of the rotating base 1c. A partition 1d is provided between the two working areas 1b. With this design, the weld seams of two battery boxes 7 can be ground simultaneously using one positioning platform 1, avoiding the need for an additional positioning platform 1.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
