Description

Technical Field

[0001] This invention relates to the field of external rotor manufacturing technology, and in particular to an external rotor assembly and testing device. Background Technology

[0002] An external rotor motor is a motor whose rotor is located outside the stator. The external rotor assembly includes a motor housing, a motor shaft, and magnets mounted inside the housing. The magnets are typically glued directly to the inner circumference of the motor housing. A shaft hole is located at the bottom of the motor housing, and the motor shaft is interference-fitted with this hole. External rotor motors require high concentricity between the motor shaft and the rotor's inner bore. After the rotor is press-fitted into the motor housing's shaft hole, a runout test is necessary. During the assembly of the external rotor, many processes, such as incoming material inspection, component transfer, assembly, and final product inspection and sorting, require manual intervention. This results in low production efficiency and a low degree of automation, especially in batch production where ensuring product consistency is difficult. Summary of the Invention

[0029] refer to Figure 14 , Figure 15 The runout detection device 8 is used to detect the radial runout of the motor housing 11 carried by the detector. The runout detection device 8 includes a runout detection platform 81, a runout detection rotating mechanism 82, a runout detection frame 83, a runout detection lifting mechanism 84, a runout detection translation mechanism 85, and a runout sensor 86. The runout detection rotating mechanism 82 is mounted on the frame 2, and the runout detection platform 81 is mounted on the rotating end of the runout detection rotating mechanism 82. The runout detection rotating mechanism 82 is an electric turntable or a rotary motor.

[0030] The vibration detection platform 81 has a third groove structure 801, which is inserted into the motor shaft 12 inside the motor housing 11. The vibration detection platform 81 is powered by the motor housing 11 with its open side facing down. The vibration detection frame 83 is set on the frame 2. The vibration detection lifting mechanism 84 is set on the frame 2. The vibration detection translation mechanism 85 is set on the lifting end of the vibration detection lifting mechanism 84. Both the vibration detection lifting mechanism 84 and the vibration detection translation mechanism 85 are telescopic cylinders or electric push rods. The vibration sensor 86 is set on the translation end of the vibration detection translation mechanism 85. The vibration translation mechanism and the vibration lifting mechanism cooperate with each other to adjust the position of the vibration sensor 86 in the horizontal and vertical directions, so that the sensing end of the vibration sensor 86 abuts against the outer wall of the motor housing 11 on the vibration detection platform 81.

[0031] The vibration sensor 86 includes an upper vibration sensing plate 861, a lower vibration sensing plate 862, a zero-adjustment cylinder 863, a displacement sensor 864, and a vibration sensing rod 865. A first reset plate 8601 and a second reset plate 8602 are respectively arranged on opposite sides of the upper vibration sensing plate 861 and the lower vibration sensing plate 862. The zero-adjustment cylinder 863 is mounted on the first reset plate 8601, and a zero-adjustment rod is mounted on the second reset plate 8602. The extension and retraction end of the zero-adjustment cylinder 863 corresponds to the zero-adjustment rod. A displacement sensor 864 is provided on the position plate 8601. The sensing end of the displacement sensor 864 corresponds to the second reset plate 8602. Two elastic connectors 8603 are symmetrically arranged between the upper bounce sensing plate 861 and the lower bounce sensing plate 862. The elastic connectors 8603 consist of an upper connecting strip, a lower connecting strip, and two spring sheet structures disposed between the upper connecting strip and the lower connecting strip. The upper bounce sensing plate 861 and the lower bounce sensing plate 862 are relatively movable and have an elastic reset function. The upper bounce sensing plate 861 is disposed on the translation end of the bounce detection translation mechanism 85. The upper end of the bounce sensing rod 865 is disposed on the lower bounce sensing plate 862. The lower end of the bounce sensing rod 865 forms a bounce sensing part. The outer wall of the bounce sensing part is a circumferential surface. The bounce sensing part is the sensing end of the bounce sensor 86. The zero-adjustment cylinder 863 is used to adjust the relative position between the first reset plate 8601 and the second reset plate 8602, thereby facilitating the zero-adjustment operation of the displacement sensor 864.

[0032] Preferably, the fourth and fifth station clamping mechanisms 302 on the progressive workstation plate 35 of the progressive pick-and-place device 3 are both equipped with a flipping drive mechanism 303. The two flipping drive mechanisms 303 drive the fourth and fifth station clamping mechanisms 302 to rotate respectively. The fourth station clamping mechanism 302 places the motor housing 11 with the motor shaft 12 pressed on it onto the runout detection table 81. The corresponding flipping drive mechanism 303 drives the fourth station clamping mechanism 302 to rotate 180°, so that when the motor housing 11 is placed on the runout detection table 81 of the runout detection device 8, the opening side of the motor housing 11 faces downward. The runout detection rotating mechanism 82 drives the runout detection table 81 to rotate. The motor shaft 12 pressed inside the motor housing 11 rotates with the runout detection table 81. The runout detection lifting mechanism 84 and the runout detection translation mechanism 85 adjust the position of the runout sensor 86 so that its sensing end abuts against the outer wall of the motor housing 11 on the runout detection table 81, thereby detecting the radial runout of the motor housing 11. After the radial runout of the motor housing 11 is detected, the fifth station clamping mechanism 302 places the motor housing 11 with the motor shaft 12 pressed on it onto the second product discharge device 9 or the finished product discharge conveyor belt 10. The corresponding flipping drive mechanism 303 drives the fourth station clamping mechanism 302 to flip 180° so that the motor housing 11 is placed on the second product discharge device 9 or the finished product discharge conveyor belt 10 with the open side facing upward.

[0033] refer to Figures 1 to 15When the assembly and testing equipment is in use, the progressive pick-and-place device 3 is equipped with a six-station clamping mechanism 302, which can move progressively between six different processes, so that the motor housing 11 can be sequentially fed to the feeding and height adjustment device 4, the magnet detection device 5, the first-stage product discharge device 6, the shaft insertion and pressing device 7, the runout detection device 8, the second-stage product discharge device 9, and the finished product discharge conveyor belt 10. The housing feeding conveyor belt 13 transports the motor housing 11 to be assembled to the housing feeding device 14. The housing feeding device 14 adjusts the housing through the housing feeding translation mechanism 142 and the housing feeding lifting mechanism 143. The position of the loading clamping mechanism 144 allows it to transfer the motor housing 11 from the housing feeding conveyor belt 13 to the loading lifting platform 42 of the loading height adjustment device 4. The loading height adjustment device 4 adjusts the height of the loading lifting platform 42 via the loading lifting mechanism 43 so that it carries the motor housing 11 and enters the picking range of the progressive pick-and-place device 3. Then, the progressive pick-and-place device 3 synchronously adjusts the position of the station clamping mechanism 302 via the first progressive translation mechanism 33, the second progressive translation mechanism 34, and the progressive lifting mechanism 36, thereby picking up and discharging the motor housing 11. 11 is moved to the magnet detection device 5, which detects whether the magnet body 112 inside the motor housing 11 is missing. If the number of magnet bodies 112 inside the motor housing 11 is missing, the progressive pick-and-place device 3 sends the motor housing 11 to the first-stage product discharge device 6 for defective product discharge. If the magnet bodies 112 inside the motor housing 11 are complete, it is sent to the shaft insertion pressing device 7, and the progressive pick-and-place device 3 moves the motor housing 11 to the pressing table 73 of the shaft insertion pressing device 7. The shaft insertion pressing device 7 is used to supply the motor shaft 12 and press the motor shaft 12 onto the motor housing 11. After the motor housing 11 is pressed together, the progressive pick-and-place device 3 places the pressed motor housing 11 in the correct position on the runout detection table 81. The runout detection device 81 detects the radial runout of the motor housing 11. If the radial runout of the motor housing 11 fails the test, the progressive pick-and-place device 3 places the motor housing 11 that has passed the radial runout test on the second product discharge device 9 for defective product discharge. If the radial runout of the motor housing 11 passes the test, the progressive pick-and-place device 3 places the motor housing 11 that has passed the radial runout test on the finished product discharge conveyor belt 10 for finished product discharge.

[0034] This assembly and testing equipment enables the adjustment of the height of the motor housing 11, the detection of the number of magnet bodies 112 inside the motor housing 11, the discharge of defective products after magnet inspection, the pressing of the motor housing 11 and the motor shaft 12, the detection of radial runout of the motor housing 11, the discharge of defective products after radial runout inspection, and the discharge of finished products. The setting of the first product discharge device 6 and the second product discharge device 9 allows the staff to classify and collect defective products after magnet inspection and radial runout inspection, thereby classifying and reworking them and improving rework efficiency. The various devices of this assembly and testing equipment work together to realize automated assembly and testing, reduce manual intervention, and improve the production efficiency and product quality of the outer rotor assembly 1.

[0035] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
