Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet synchronous motors for new energy vehicles, and in particular to a rapid and automatic locking test device. Background Art

[0002] In the production and manufacturing of motors and controllers, major domestic suppliers have basically achieved fully automatic or semi-automatic assembly. However, there are still a few processes that require manual operation (such as performance testing, signal harness docking, electrical performance testing, etc.), resulting in a low level of quality control and failure to meet customer quality requirements.

[0003] In the controller performance test process, manufacturers of permanent magnet synchronous motor controllers for new energy vehicles use employees to manually take the power wiring harness and directly connect it to the three-phase terminals and DC bus terminals of the controller with high-current alligator clips. The operation requirements are that the positive and negative of the DC bus cannot be reversed, the clamping position cannot be misplaced, and the connection is reliable. The existing process is difficult for employees to operate and has low efficiency. The positive and negative poles are easily reversed and damage the product, and it cannot meet the quality requirements, resulting in a high failure rate in the performance test of this process. Due to the positive and negative pole requirements and the three-phase sequence requirements, as long as the clamping polarity and position are wrong, the performance test products that fail can only be scrapped. Therefore, the current assembly process urgently needs a new rapid anti-error locking process to solve the practical problem. To this end, a rapid automatic locking test device is proposed.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-4As shown, a rapid automated locking test device includes a base 1, a three-phase line locking mechanism 4 and a busbar locking mechanism 5. Two parallel slide rails 2 are installed on the base 1, and a slide 3 is slidably connected to the two slide rails 2. The slide 3 is used to transport the motor controller. The three-phase line locking mechanism 4 is installed on the base 1 and is used to realize the connection between the three-phase power harness and the three-phase connection support on the motor controller. The busbar locking mechanism 5 is installed on the base 1 and is used to realize the connection between the DC bus power harness and the busbar connection support on the motor controller.

[0020] In this embodiment, the three-phase line locking mechanism 4 includes a first tooling seat 42 and a first tooling cover 43. The first mounting seat 41 is installed on the base 1. The first tooling seat 42 is connected to the upper end of the first mounting seat 41. The first tooling seat 42 is connected to the first tooling cover 43. A three-phase line bus 44 is provided on the first tooling seat 42 and the first tooling cover 43.

[0021] In this embodiment, the busbar locking mechanism 5 includes a second tooling seat 54 and a second tooling cover 55. A guide rail 51 is installed on the base 1. A slider 52 is slidably connected to the guide rail 51. The slider 52 is connected to the second mounting seat 53. The second tooling seat 54 is connected to the upper end of the second mounting seat 53. The second tooling seat 54 is connected to the second tooling cover 55. The second tooling seat 54 and the second tooling cover 55 are provided with a busbar 56.

[0022] In this embodiment, a position sensor is provided on the guide rail 51 for detecting the position of the slider 52 and determining whether the busbar 56 is properly connected to the busbar connection support on the motor controller product.

[0023] In this embodiment, the first tooling seat 42 , the first tooling cover 43 , the second tooling seat 54 and the second tooling cover 55 are all made of glass fiber, which has good insulation and voltage resistance properties.

[0024] Working process and principle:

[0025] Before work, first connect the three-phase power harness for testing to the tail end of the three-phase bus 44, and at the same time connect the positive and negative poles of the DC bus power harness to the bus bar 56. During work, the motor controller is automatically grabbed by the robot and positioned on the slide 2, and then the slide 2 is controlled to slide so that the motor controller approaches the three-phase line locking mechanism 4 and the busbar locking mechanism 5. After the slide 2 slides into place, the three-phase bus 44 just corresponds to and contacts the three-phase connection support on the motor controller. At this time, an electric torque gun and an adapter bit are used manually to take the bolts for locking. Afterwards, the operator pushes the second mounting seat 53 to insert the busbar 56 into the busbar busbar and the busbar connection on the motor controller, then takes out the bolts for manual tightening, starts the automatic test to detect the performance of the motor controller, and uses the three-phase line locking mechanism 4 and the busbar locking mechanism 5 to automatically and accurately position and lock the product with the three-phase and busbar tooling, avoiding three-phase position errors, busbar polarity errors, and preventing the hidden dangers of performance test failures caused by poor contact, which not only saves manpower and reduces costs, but also improves test efficiency and increases product production capacity.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
