Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and specifically to a motor conductivity detection device. Background Technology

[0002] An electric motor is an important power input device. Its production process involves multiple steps. When assembling an electric motor, the rotor needs to be accurately installed into the stator, and the end cover needs to be riveted to the housing through the shaft.

[0003] After the motor is assembled, it needs to be powered on to test whether its current, speed and noise are qualified. The motor is usually mounted on a tooling plate to move between processes to realize its assembly operation. The frequency of plugging and unplugging the motor circuit is not high. The manual plugging and unplugging method is not compatible with the work rhythm of the assembly line and will also increase production costs. The complexity of the circuit also makes it difficult to automate the plugging and unplugging of the motor's power circuit.

[0004] Based on this, the present invention designs a motor conductivity detection device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a motor conductivity detection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A motor conductivity detection device includes an energizing trigger component, an auxiliary fixing component, and a positioning component mounted on a frame of a double-speed chain conveyor.

[0008] The positioning component is used to determine whether the motor is in place, the power-on trigger component is used to power on the motor, and the auxiliary fixing component is used to fix the motor when it is powered on.

[0009] The power-on triggering component includes a power-on component for supplying power to the power strip and a triggering component for pressing the elastic lever to make the motor wires connected to the power strip.

[0010] Furthermore, the triggering assembly includes a triggering cylinder and a pressure rod. The triggering cylinder is fixedly installed on the frame of the double-speed chain conveyor via a connector. The output end of the triggering cylinder is fixedly installed with three pressure rods that correspond one-to-one with the elastic levers of the wiring terminals and cooperate to press the elastic levers.

[0011] Furthermore, the power-on component includes a power-on cylinder and a plug. The power-on cylinder is fixedly mounted on the frame of the double-speed chain conveyor via a connector. The output end of the power-on cylinder is fixedly mounted with a plug that mates with a power strip. The plug is electrically connected to an external power supply device via a wire.

[0012] Furthermore, the auxiliary fixing components are provided in two sets and symmetrically distributed on the front and rear sides of the frame of the double-speed chain conveyor. The two sets of auxiliary fixing components work together to fix the motor from both sides.

[0013] Furthermore, the auxiliary fixing assembly includes a side-push cylinder and a side-pressure rod. The side-push cylinder is fixedly connected to the frame of the double-speed chain conveyor via a connector, and at least two side-pressure rods are fixedly installed at the output end of the side-push cylinder.

[0014] Furthermore, rubber heads are provided at the ends of both the side pressure bar and the pressure bar.

[0015] Furthermore, the positioning component includes a first pair of photoelectric sensors and a second pair of photoelectric sensors, both of which are mounted on the frame of the double-speed chain conveyor and distributed left and right.

[0016] Furthermore, the distance between the first pair of photoelectric sensors and the second pair of photoelectric sensors is smaller than the outer diameter of the motor housing.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. The precise positioning of the motor is achieved by the cooperation of the first photoelectric sensor, the second photoelectric sensor, and the lower stop and check device of the double-speed chain conveyor. Then, the pressure rod presses down on the elastic block, and the plug is connected to the power strip to power on the motor. At the same time, two sets of auxiliary fixing components work together to fix the motor from both sides to prevent the motor position from shifting due to vibration during operation, thereby realizing the conductivity detection of the motor and judging whether the current, speed and noise of the motor are qualified.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3An automated assembly line for motor rotors includes a double-speed chain conveyor 1, a tooling plate 2 running on the double-speed chain conveyor 1, and a rotor assembly module 3, an end cap riveting module 4, and a conductivity detection module 5 arranged sequentially along the conveying direction of the double-speed chain conveyor 1.

[0033] Although the illustration is omitted, the lower side of the double-speed chain conveyor line 1 is equipped with multiple sets of stoppers and check valves for precise positioning of the tooling plate 2. After the assembled housing 61 and stator 62 are placed on the tooling plate 2 by manual labor or a robotic arm, the tooling plate 2 flows from left to right. The rotor 63 is installed into the stator 62 by the rotor assembly module 3, and then the end cover 64 is riveted to the top of the housing 61 by the end cover riveting module 4, completing the assembly of the motor 6. Finally, the three wires of the motor 6 are energized by the conductivity detection module 5 to test whether the motor can be energized smoothly. Qualified products flow into the next process, and unqualified products are removed from the double-speed chain conveyor line 1 by manual labor or a robotic arm.

[0034] Example 2: In some embodiments, please refer to the accompanying drawings. Figures 4-6 A stator moving carrier that facilitates communication, including tooling plate 2;

[0035] The tooling plate 2 is provided with a material placement seat 21 for positioning the housing 61;

[0036] The material placement seat 21 consists of an outer annular block 211 and an inner annular block 212 disposed inside the outer annular block 211. Both the outer annular block 211 and the inner annular block 212 are fixedly connected to the tooling plate 2. The inner diameter of the outer annular block 211 is larger than the outer diameter of the housing 61 of the motor 6, so that the outer annular block 211 can completely accommodate the housing 61 and achieve the positioning effect of the motor 6. There is a certain gap between the inner wall of the outer annular block 211 and the housing 61, so that the outer annular block 211 can adapt to various different specifications of motors 6. The height of the inner annular block 212 is lower than the height of the outer annular block 211. The inner annular block 212 is used to support the bottom of the housing 61. The outer annular block 211 and the inner annular block 212 work together to achieve the positioning effect of the motor 6. The tooling plate 2 is also provided with a circular groove 214, which is located inside the inner annular block 212 and is used to avoid the protrusion at the bottom of the housing 61. The outer annular block 211, the inner annular block 212 and the circular groove 214 are concentrically arranged.

[0037] The outer annular block 211 is provided with a receiving groove 213. There are multiple receiving grooves 213, and the receiving grooves 213 are evenly distributed at equal intervals along the circumference of the outer annular block 211. The receiving grooves 213 not only facilitate the manual or robotic arm to pick up and put down the motor 6, but also facilitate the arrangement of the motor 6's wires.

[0038] The tooling plate 2 is fixedly installed with a power strip 22 for connecting to the power supply and a terminal block 23 for connecting to the wires of the motor 6. The power strip 22 and the terminal block 23 are electrically connected. The terminal block 23 is provided with three sockets 231, which are respectively used to connect to the ends of the three wires of the motor 6. The terminal block 23 is also provided with three elastic levers 232 that correspond one-to-one with the sockets 231. By pressing the elastic levers 232, the wires in the sockets 231 can be controlled to conduct.

[0039] Multiple cable management posts 24 are fixedly installed on the tooling plate 2. By passing the wires through the cable management posts 24, the wiring can be made neat and clear, which facilitates the operation of the motor 6. Preferably, the top of the cable management post 24 is provided with a locking block to further increase the effect of preventing the wires on the cable management post 24 from falling off.

[0040] Example 3: In some embodiments, such as Figures 7-10 As shown, in a preferred embodiment of the present invention, a motor conductivity detection device includes an energizing trigger component 51, an auxiliary fixing component 52 and a positioning component 53 mounted on the frame of the double-speed chain conveyor line 1. The positioning component 53 is used to determine whether the motor 6 is in place, the energizing trigger component 51 is used to energize the motor 6, and the auxiliary fixing component 52 is used to fix the motor 6 when it is energized.

[0041] The power-on triggering assembly 51 includes a trigger cylinder 511, a pressure rod 512, a power-on cylinder 513, and a plug 514. The trigger cylinder 511 is fixedly installed on the frame of the double-speed chain conveyor line 1 via a connector. The output end of the trigger cylinder 511 is fixedly installed with three pressure rods 512 that correspond one-to-one with the elastic levers 232 of the terminal block 23 and cooperate to press the elastic levers 232. The power-on cylinder 513 is also fixedly installed on the frame of the double-speed chain conveyor line 1 via a connector. The output end of the power-on cylinder 513 is fixedly installed with a plug 514 that is connected to the power strip 22. The plug 514 is electrically connected to an external power supply device via a wire.

[0042] The auxiliary fixing components 52 are provided in two sets and symmetrically distributed on the front and rear sides of the frame of the double speed chain conveyor line 1. The two sets of auxiliary fixing components 52 cooperate to fix the motor 6 from both sides to prevent the position of the motor 6 from shifting due to vibration during operation.

[0043] The auxiliary fixing component 52 includes a side push cylinder 521 and a side pressure rod 522. The side push cylinder 521 is fixedly connected to the frame of the double speed chain conveyor line 1 through a connector. At least two side pressure rods 522 are fixedly installed at the output end of the side push cylinder 521. The ends of the side pressure rods 522 and the pressure rods 512 are provided with rubber heads to increase friction and buffer.

[0044] The positioning component 53 includes a first pair of photoelectric sensors 531 and a second pair of photoelectric sensors 532. Both the first pair of photoelectric sensors 531 and the second pair of photoelectric sensors 532 are mounted on the frame of the double-speed chain conveyor line 1 and are distributed left and right. When the double-speed chain conveyor line 1 drives the motor 6 to pass through the first pair of photoelectric sensors 531, it indicates that the motor 6 is about to be in position. When the motor 6 leaves the first pair of photoelectric sensors 531 and passes through the second pair of photoelectric sensors 532, it indicates that the motor 6 has been in position. The first pair of photoelectric sensors 531, the second pair of photoelectric sensors 532, and the stop and anti-return device on the lower side of the double-speed chain conveyor line 1 work together to achieve precise positioning of the motor 6.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
