Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically to a wire removal mechanism for continuous motor testing. Background Technology

[0002] In automated motor testing processes, when a motor fails noise, withstand voltage, or turn spacing tests, the motor wires must be promptly removed from the terminal clamps on the test base to prevent defective products from entering subsequent stations and causing invalid testing. Current technologies often rely on manual operation for wire removal, which is inefficient and prone to damaging the wires or terminal clamps. Therefore, a wire removal mechanism that precisely matches the test base is needed to automate and non-destructively remove the wires, ensuring the continuity and reliability of the testing process. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wire removal mechanism for continuous testing of motors, comprising: The equipment includes a machine, a cyclic test base, and at least one set of wire removal mechanisms. The cyclic test base includes a support plate, a fixed base on the support plate, and a wire clamp. The wire clamp is located at one end of the fixed base near the outside of the machine and is used to connect the motor wire. The wire removal mechanism is located above the movement path of the cyclic test base and is set corresponding to the wire clamp. It includes a pressing component and a wire taking component. The pressing component is directly opposite the wire clamp and is used to drive the wire clamp to release the motor wire. The wire taking component is located directly above the wire clamp and the fixed base and is used to clamp and pull out the motor wire released by the pressing component.

[0004] According to one embodiment of the present invention, the pressing component includes a first linear drive member and a pressure plate. The first linear drive member is suspended directly above the terminal clamp, with its driving end facing the terminal clamp. The pressure plate is located at the driving end of the first linear drive member and presses the terminal clamp downward with the driving of the first linear drive member.

[0005] According to one embodiment of the present invention, the wire taking assembly includes a second linear drive and a wire clamping drive. The second linear drive is located directly above the junction box and the fixed base, with its driving end facing the support plate.

A conductive wheel is provided on the lower surface of the support plate. The conductive wheel is in contact with the conductive rail.

When the wire taking assembly pulls out the motor wire, the electrical connection between the terminal clamp and the motor is disconnected.

[0007] According to one embodiment of the present invention, the wire removal mechanism includes multiple sets, which are arranged sequentially along the movement direction of the test base, and are used to remove wires tested at different workstations.

[0008] According to one embodiment of the present invention, the fixed base includes a base and a pushing component. The base includes a support seat and a stop block. The stop block is located at one end of the support seat near the outer side of the machine platform, and the pushing component is located at the other end of the support seat and faces the support seat.

However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential.

They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features.

[0015] See Figures 1-4 , Figure 1 This is one of the structural schematic diagrams of the wire removal mechanism for continuous motor testing in the embodiments. Figure 2 This is the second schematic diagram of the wire removal mechanism for continuous motor testing in the embodiment. Figure 3 This is a schematic diagram of the wire removal mechanism and the cyclic test base structure in the embodiment. Figure 4 This is a schematic diagram of the power supply rail structure in the embodiment. The example of a continuous motor testing wire removal mechanism includes a machine base 1, a cyclic testing base 2, and at least one set of wire removal mechanisms 3. The cyclic testing base 2 includes a support plate 21, a fixed base 211 disposed on the support plate 21, and a wire clamp 212. The wire clamp 212 is located at one end of the fixed base 211 near the outside of the machine base 1 and is used to connect the motor wire. The wire removal mechanism 3 is located above the movement path of the cyclic testing base 2 and is positioned corresponding to the wire clamp 212. It includes a pressing component 31 and a wire extraction component 32. The pressing component 31 is directly opposite the wire clamp 212 and is used to drive the wire clamp 212 to release the motor wire. The wire extraction component 32 is located directly above the wire clamp 212 and the fixed base 211 and is used to clamp and extract the motor wire released by the pressing component 31. When in use, the motor is placed on the fixed base 211 and electrically connected to the terminal clamp 212. At this time, the motor and the fixed base 211 undergo aging tests. If any motor fails the aging test, the pressing component 31 presses down on the terminal clamp 212, causing the terminal clamp 212 to release the motor wires. Then, the wire removal mechanism 32 removes the motor wires to disconnect the power supply to the motor, preventing it from entering the next testing station for invalid testing. It is understood that in practical implementation, this scheme can be used to set up multiple different testing stations for testing, such as noise testing and turn spacing testing. This scheme can be used to disconnect unqualified products and prevent them from undergoing invalid testing at the next testing station.

[0016] Furthermore, the pressing assembly 31 includes a first linear drive 311 and a pressure plate 312. The first linear drive 311 is suspended directly above the terminal clamp 212, with its drive end facing the terminal clamp 212. The pressure plate 312 is located at the drive end of the first linear drive 311 and presses the terminal clamp 212 downward as the first linear drive 311 drives it. The first linear drive 311 is a cylinder. In other words, by driving the pressure plate 312 downward through the first linear drive 311, the pressure plate 312 presses down on the terminal clamp 212, thus releasing the connection between the terminal clamp and the motor wire. The wire can then be retrieved by the wire-retrieving assembly 32.

[0017] Specifically, the wire-taking assembly 32 includes a second linear drive 321 and a wire-clamping drive 322. The second linear drive 322 is located directly above the junction box 212 and the fixed base 211, with its drive end facing the support plate 21. The wire-clamping drive 322 is located at the drive end of the second linear drive 321 and is used to clamp the motor wire. In this example, the second linear drive 321 is also a cylinder, while the wire-clamping drive 322 is a Y-type finger cylinder. Driven by the second linear drive 321, the wire-clamping drive 322 can move towards the motor wire until it reaches the motor wire. The wire-clamping drive 322 then clamps the motor wire, and the second linear drive 321 resets. In this way, the motor wire can be removed from the junction box 212.

[0018] Furthermore, the machine tool 1 is equipped with multiple conductive rails 11, which are arranged sequentially end-to-end along the length of the machine tool 1. A conductive wheel 213 is provided on the lower surface of the support plate 21, and the conductive wheel 213 is in contact with the conductive rail 11. A wire clamp 212 is electrically connected to the conductive wheel 213. When the wire extraction assembly 32 pulls out the motor wire, the electrical connection between the wire clamp 212 and the motor is broken. It can be understood that by setting multiple conductive rails 11, in actual use, aging power supply equipment and withstand voltage testing equipment can be set within the machine tool 1 and connected to different conductive rails 11. This not only ensures the continuity of power supply at each station during testing but also ensures that the power supply for each station is independent and does not affect each other. Of course, the number of conductive rails can be set according to the needs of different stations, which will not be elaborated here. Similarly, the wire extraction mechanism includes multiple sets, arranged sequentially along the movement direction of the test base 211, and is used for extracting wires tested at different stations.

[0019] Further, the fixed base 211 includes a base 2111 and a pushing assembly 2112. The base 2111 includes a support 21111 and a stop 21112. The stop 21112 is located at one end of the support 21111 near the outer side of the machine base 1, and the pushing assembly 2112 is located at the other end of the support 21111 and faces the support 21111. The pushing assembly 2112 includes a pushing drive 21121 and a push block 21122. The pushing drive 21121 is a linear electric cylinder, which is also electrically connected to the conductive wheel 213. When the motor is placed on the base 2111, the pushing drive 21121 pushes the motor so that the motor abuts against the stop block 21112, thereby limiting the position of the motor and ensuring the consistency of the motor position. In a specific implementation, the stop block 21112 and the support base 21111 are made of bakelite.

[0020] Furthermore, the cyclic test base 2 also includes a cyclic mechanism 22, which includes a chain 221, a sprocket 222 and a sprocket drive 223. The chain 222 is driven by the sprocket 222, the sprocket 222 is driven by the sprocket drive 223, the support plate 21 is connected to the chain 211, and the sprocket drive 223 adopts a servo drive mechanism.

[0021] In summary, in this example, the power supply to the motor is disconnected by removing the motor's wires through the wire-retrieving mechanism, preventing it from entering the next testing station for invalid testing and ensuring the continuity and reliability of the testing process.

[0022] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
