Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle motor manufacturing and transportation, and in particular to a motor transfer device and a transfer method. Background Art

[0002] New energy vehicles (NEVs) are vehicles that utilize unconventional automotive fuels as their power source (or conventional automotive fuels with novel onboard power units), integrating advanced technologies in vehicle power control and drive to create advanced technical principles, new technologies, and new structures. New energy vehicles include four major categories: hybrid electric vehicles (HEVs), battery electric vehicles (BEVs, including solar-powered vehicles), fuel cell electric vehicles (FCEVs), and other new energy vehicles (e.g., vehicles using high-efficiency energy storage devices such as supercapacitors and flywheels). The conventional method for transporting motors in NEVs is manual transport, which is not only time-consuming and labor-intensive but also highly dangerous when the motors need to be placed in high locations. Furthermore, manual transport is unstable and can easily damage the battery pack due to bumps and other issues. Therefore, the present invention provides a motor transport device and method.

[0003] In the prior art, a Chinese patent document with publication number CN114750812A and publication date July 15, 2022 is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A battery pack transfer device and method for new energy vehicles, the output end of the lifting motor rotates the lifting screw through the coupling, and the lifting screw then drives the lifting platform to achieve clamping at different heights, start the clamping motor, and the output end of the clamping motor drives the driving shaft to rotate through the coupling, and the driving shaft then rotates the driving gear, and the driving gear thereby drives two driven gears that are meshed with each other to rotate, and the two driven gears thereby drive the two clamping arms so that the two clamping arms move away from each other, and the two mechanical claws move away from each other on both sides with the connecting bolt as the rotation center, the clamping motor rotates in the opposite direction, and the two driven gears drive the two clamping arms closer to each other, and the two mechanical claws move closer to each other on both sides with the connecting bolt as the rotation center, so that the clamping frame and the slope bottom plate can clamp and transfer the battery pack, replacing manual transfer, saving time and effort.

[0004] In order to solve the problem that manual transfer is not only time-consuming and labor-intensive, but also very dangerous when the battery pack needs to be placed at a higher position, and on the other hand, manual transfer is unstable and prone to bumps and other problems, the existing technology uses a lifting motor and mechanical claw clamping method to handle it. However, there is still a situation where only one set of mechanical claws can transfer a single motor at a time, which leads to low transfer efficiency. Summary of the Invention

[0005] The present invention provides a motor transfer device and a transfer method to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0012] A further improvement of the technical solution of the present invention is that: the inner wall of the middle portion of the moving block is threadedly connected to the outer surface of the threaded rod, and telescopic rods are fixedly installed on both sides of the moving block.

[0013] By adopting the above technical solution, the limiting movable crossbeam limits the movable block, and the telescopic rod mainly enables the motor clamping fixed plate to be lowered and the motor clamping fixed plate to be lifted.

[0014] A further improvement of the technical solution of the present invention is that the lifting unit includes a motor clamping fixed plate fixedly installed at the output end of telescopic rod one, telescopic rod two is fixedly installed in the middle of the motor clamping fixed plate, and a pushing block is fixedly installed at the output end of telescopic rod two.

[0015] With the above technical solution, the telescopic rod 2 and the telescopic rod 3 mainly control the rotation and opening and closing of the grabbing clamp to clamp and fix the motor.

[0016] A further improvement of the technical solution of the present invention is that a gripping clamp is rotatably mounted on the lower surface of the motor clamping fixed disk, a connecting rod is hingedly mounted on the upper end of the gripping clamp, and the lower end of the connecting rod is rotatably connected to the side wall of the pushing block.

[0017] By adopting the above technical solution, the connecting rod connects the pushing block so that the clamp flips outward to select the motor when the telescopic rod pushes the pushing block downward, and then the clamp just clamps the motor when the telescopic rod resets.

[0018] A further improvement of the technical solution of the present invention is that: the placement unit includes an annular placement rack fixedly installed on the outer surface of the mobile transfer rack, the upper surface of the annular placement rack is fixedly installed with a placement fixing platform, the middle upper surface of the placement fixing platform is fixedly installed with a center placement plate, the inner surface of the placement fixing platform is rotatably installed with a driving gear, the lower surface of the placement fixing platform is fixedly installed with motor 2, and the output shaft of motor 2 is fixedly connected to the lower end of the rotating shaft of the driving gear.

[0025] S1. Clamp and lift the new energy vehicle motor;

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0029] 1. The present invention provides a motor transfer device and transfer method. When the motor at the bottom of the rotating column works, the rotating column can rotate and reverse. In conjunction with the distribution of the annular placement rack, the new energy vehicle motors are transported to the placement and fixed platform on the annular placement rack in sequence, realizing the rotation of multiple groups of new energy vehicle motors at one time, thereby improving the efficiency of transfer.

[0030] 2. The present invention provides a motor transfer device and transfer method. The threaded rod is driven to rotate by a driving motor installed at one end of a limit moving beam, prompting the moving block to move to the outside of the annular placement rack under the limited cooperation of the limit moving beam. The telescopic rod 1 descends to make the motor clamping fixed plate adapt to the height of the new energy vehicle motor placed on the ground. The telescopic rod 2 works to push the pushing block downward to rotate the connecting rod, prompting the clamp to flip outward to select the outer ring of the motor. Then the telescopic rod 2 is reset to make the pushing block move up. At this time, the clamp clamps the motor inward to fix it, and cooperates with the contraction of the telescopic rod 1 and the movement of the moving block to automatically lift the motor to the annular placement rack, replacing manual transfer, saving time and effort, and avoiding bumps.

[0031] 3. The present invention provides a motor transfer device and a transfer method. A plurality of placement and fixing platforms are fixedly installed on the annular placement frame. A central placement plate is provided on the placement and fixing platform to independently place the motor. When the motor works, a group of drive gears rotates on the inner side of the placement and fixing platform. The four groups of drive gears are meshed and connected through a gear ring, so that the four groups of drive gears rotate at the same time. The movable rack is engaged with the drive gear and moves at the same time under the limit cooperation of the placement and fixing platform, so that the clamping protection block slides from the outside to the inside to protect the upper outer surface of the motor, thereby increasing the stability of the motor during transportation.

[0032] 4. The present invention provides a motor transfer device and transfer method. When the elastic pad on the inner side of the clamping protection block contacts the side wall of the new energy vehicle motor, it undergoes elastic deformation due to extrusion, and the arc-shaped outward expansion increases the support force on the motor side wall. The reset spring rope uses elasticity to elastically pull the front end of the elastic pad, so that the elastic pad always has a centripetal elastic supporting force, which effectively performs shock-absorbing and buffering protection on the side wall of the new energy vehicle motor.
