[0002] At present, extruded aluminum alloy battery trays meet different needs through the splicing and processing of profiles, and have the advantages of flexible design, convenient processing, and easy modification. In terms of performance, extruded aluminum alloy battery trays have high rigidity, vibration resistance, extrusion and impact resistance, and can meet various energy requirements through the welding and processing of different aluminum profiles. At the same time, it is easy to modify the design and adjust the materials used. The frame structure is more conducive to lightweight and strength assurance of different structures. The outer frame mainly completes the bearing function of the entire battery system, and the inner frame mainly completes the bearing function of modules, water cooling plates and other sub-modules. The middle protective surface of the inner and outer frames mainly completes the isolation and protection of the battery pack from the outside world, such as gravel impact, waterproofing, heat insulation, etc. Aluminum battery trays are the most widely used products, and most car companies will choose aluminum alloy materials to make battery trays;

However, the existing technology combines manual operation and traditional milling equipment to perform milling processing on the battery tray. The efficiency is low, and there are problems such as processing errors and easy physical harm to workers;

[0004] For this purpose, we designed an automatic commutator slot milling machine for battery tray processing. Summary of the invention

Specific implementation mode

[0027] Refer to Figure 1-Figure 5 , an automatic commutator milling machine for battery tray processing, including a mounting frame 1, an industrial robot 3 for milling the battery tray, and a control board. A pair of first chutes 4 are opened on the inner wall of the mounting frame 1. A pair of moving platforms 6 move relatively on the pair of first chutes 4. A clamping and fixing mechanism is provided on the moving platform 6, and the clamping and fixing mechanism is used to clamp and fix battery trays of different sizes;

[0028] The clamping and fixing mechanism includes a pair of corner clamping members 10 for clamping and fixing the four corners of the battery tray. The clamping and fixing mechanism further includes a second motor 8 and a second left - right screw rod 9. A second chute and a mounting cavity are opened on the moving platform 6. The second motor 8 is fixedly installed in the mounting cavity. The second left - right screw rod 9 is arranged in the second chute. The output end of the second motor 8 is coaxially and fixedly connected to the second left - right screw rod 9. By driving the second left - right screw rod 9 to rotate through the second motor 8, a pair of corner clamping members 10 move relatively in the second chute to clamp and fix the corners at both ends of the battery tray;

[0029] The clamping and fixing mechanism further includes a pair of sliding blocks 7 and a pair of sliding connection blocks. The pair of sliding blocks 7 are symmetrically arranged on both sides of the moving platform 6 respectively. Threaded holes adapted to the threads of the first left - right screw rod 5 are opened on the pair of sliding blocks 7 respectively. The pair of sliding connection blocks are symmetrically arranged in the second chute. Threaded holes adapted to the threads of the second left - right screw rod 9 are opened on the pair of sliding connection blocks respectively. The end of the sliding connection block away from the moving platform 6 is fixedly connected to the corner clamping member 10. By driving the pair of first left - right screw rods 5 to rotate through the first motor 12, the pair of moving platforms 6 move relatively between the mounting frames 1. By driving the second left - right screw rod 9 to rotate through the second motor 8, the pair of corner clamping members 10 move relatively on the moving platform 6. The effect of such a setting is that by controlling the first motor 12 and the second motor 8 to work through the control board, the two pairs of corner clamping members 10 on the pair of moving platforms 6 can clamp and fix battery trays of different sizes.

[0030] Refer to Figure 1 and Figure 5, a pair of mounting shaft platforms 14 are provided below the mounting frame 1, and a pair of support platforms 2 are provided below the mounting frame 1. A steering mechanism is provided between the pair of support platforms 2. The steering mechanism is used to adjust the angle of the battery tray, facilitating the milling process of the battery tray at different angles by the industrial robot with good accuracy and having self-locking property;

[0031] The steering mechanism includes a worm 18 for driving the mounting frame 1 to adjust the angle. The steering mechanism also includes a U-shaped rotating shaft 15 and a worm gear 16. Both ends of the U-shaped rotating shaft 15 are fixedly connected to a pair of mounting shaft platforms 14 through connecting shafts respectively. The worm gear 16 is coaxially and fixedly connected to one of the connecting shafts. The third motor 17 is fixedly installed on the support platform 2 through a motor mounting bracket. The output end of the third motor 17 is coaxially and fixedly connected to the worm 18. The worm 18 meshes with the worm gear 16. By driving the worm 18 to mesh with the worm gear 16 through the third motor 17, the U-shaped rotating shaft 15 rotates, and then the mounting frame 1 rotates. The effect of such a setting is to achieve precise angle adjustment of the rotating frame 1 according to the self-locking characteristics of the worm 18 and the worm gear 16, facilitating the milling process of the battery tray at different angles by the industrial robot 3 with high processing efficiency and good effect.

[0032] Refer to Figure 1 and Figure 5 , the U-shaped rotating shaft 15 is arranged in a U shape, so that when the third motor 17 drives the worm 18 to mesh with the worm gear 16, the U-shaped rotating shaft 15 drives the mounting frame 1 to rotate. And because the U-shaped rotating shaft 15 is arranged in a U shape, it avoids blocking the bottom of the battery tray, facilitating the industrial robot 3 to process the bottom of the battery tray.

[0033] Refer to Figure 1 and Figure 3 , a first left-right screw rod 5 is provided in each of the pair of first sliding grooves 4. A first motor 12 is fixedly installed on the side wall of the mounting frame 1. The output end of the first motor 12 is coaxially and fixedly connected to one of the first left-right screw rods 5. The pair of first left-right screw rods 5 are driven by a pair of belt pulleys and a transmission belt 13. The threads on the first left-right screw rod 5 are symmetrically arranged. When the first motor 12 drives one of the first left-right screw rods 5 to rotate, the pair of first left-right screw rods 5 rotate simultaneously, facilitating the relative movement of the pair of moving platforms 6 on the mounting frame 1.

[0034] A telescopic connecting member 11 is provided between a pair of corner clamping members 10 on the pair of moving platforms 6. The telescopic connecting member 11 includes telescopic cylinders at both ends and a connecting rod in the middle part. The telescopic cylinders at both ends of the telescopic connecting member 11 are respectively fixedly connected to a pair of corner clamping members 10 on different moving platforms 6. A pressing member for pressing and fixing the side of the upper surface of the battery tray is provided on the telescopic cylinder. Such a setting is to fix the battery tray to prevent the battery tray from detaching from the mounting frame 1 during the flipping process and ensure the processing effect of the industrial robot 3 on the battery tray.

[0035] Refer to Figure 1 and Figure 2 Figure 2 , the control board is fixedly arranged on the installation frame 1. The control board is respectively electrically connected to the industrial robot 3, the first motor 12, the second motor 8 and the third motor 17. By electrically connecting the control board to the industrial robot 3, the first motor 12, the second motor 8 and the third motor 17 respectively, the first motor 12 and the second motor 8 can be controlled to work on the control board, so that the two pairs of corner clamping members 10 on a pair of moving platforms 6 can clamp and fix battery trays of different sizes. By controlling the third motor 17 on the control board to drive the worm 18 to mesh with the worm gear 16 for transmission, the U-shaped rotating shaft 15 rotates, and then the installation frame 1 drives the battery tray to rotate, realizing the full-automatic milling operation of the battery tray. The milling operation has high working efficiency, high precision, and avoids problems such as causing physical harm to workers during the milling operation.

[0036] The working principle of the present invention is as follows:

[0037] First of all, by controlling the first motor 12 and the second motor 8 to work on the control board, the two pairs of corner clamping members 10 on a pair of moving platforms 6 can clamp and fix battery trays of different sizes, with a wide range of applications and convenient for saving the production cost of the factory. By pre-entering commands on the control board, the industrial robot 3 is controlled by the control board to perform a full-automatic milling operation on the battery tray. When it is necessary to perform a milling operation on the back or a certain angle of the battery tray, the third motor 17 is controlled by the control board to drive the worm 18 to mesh with the worm gear 16 for transmission, so that the U-shaped rotating shaft 15 rotates, and then the installation frame 1 drives the battery tray to rotate, realizing the full-automatic milling operation of the battery tray. The milling operation has high working efficiency, high precision, and avoids problems such as causing physical harm to workers during the milling operation.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
