Description

Technical Field

[0001] This utility model relates to a production device for rotor cores, and more particularly to an automatic plugging device for rotor cores. Background Technology

[0002] After the rotor cores of the motor are stacked, they need to undergo heat treatment to eliminate residual stress from stamping and restore magnetic permeability. To prevent displacement or loosening of the silicon steel sheets in the rotor core due to thermal expansion or residual stress during heat treatment, plugs are used to fix the rotor core, maintaining a tight arrangement of the sheets and ensuring the geometric and dimensional stability of the core. Therefore, a plug needs to be inserted into the center hole of the rotor core before it enters the heat treatment equipment. Currently, the plug is mainly inserted manually. Before insertion, a plug gauge needs to be inserted into the hole of the rotor core to check whether the hole is correct and whether the orientation is correct. This method is prone to misdiagnosis for large-diameter holes. After the plug is inserted, the rotor core with the plug is placed in a transfer box, which is then transferred to the feeding conveyor line of the heat treatment furnace. The rotor core is then manually placed onto the conveyor line. The overall turnover cycle is long and the overall efficiency is low. Furthermore, shaping is required after heat treatment, which is labor-intensive for operators and requires a large number of operators, resulting in high costs. Utility Model Content

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 15As shown, an automatic plug-pressing device for rotor cores includes a rotor feeding device 1, a detection and flipping device 2, a first material distribution device 3, a shaping device 4, a plug-loading device 5, a pressing detection device 6, a second material transfer device 71, a second material distribution device 72, and a discharge device 8. The rotor feeding device 1, the first material distribution device 3, the shaping device 4, the pressing detection device 6, and the plug-loading device 5 are arranged sequentially. The detection and flipping device 2 is positioned opposite to the rotor feeding device 1 and the first material distribution device 3. The second material transfer device 71 is positioned opposite to the shaping device 4, the pressing detection device 6, and the second material distribution device 72. The second material distribution device 72 is located between the second material transfer device 71 and the plug-loading device 5. The rotor feeding device 1 is used to sequentially feed out rotor cores; the detection and flipping device 2 is used to detect the positive and negative directions and bore diameter of the rotor cores and flip the rotor cores with incorrect directions; the first material distribution device 3 is used to feed out qualified and unqualified rotor cores according to the detection results; the shaping device 4 is used to shape the qualified rotor cores; the plug feeding device 5 is used to sequentially feed out plugs; the pressing detection device 6 is used to press the plugs fed out by the plug feeding device 5 into the rotor cores; the second material distribution device 72 is used to feed out plugs for pressing into qualified rotor cores and plugs for pressing into unqualified rotor cores according to the detection results; the discharge device 8 is used to feed out the rotor cores equipped with plugs. The detection and flipping device 2, the first material distribution device 3, the shaping device 4, the plug feeding device 5, the pressing detection device 6, and the second material distribution device 72 are all mounted on the frame, and the rotor feeding device 1 and the discharge device 8 are located at opposite ends of the frame. The second material transfer device 71 is used to move the rotor cores from the shaping device 4 to the pressing detection device 6.

[0033] The rotor feeding device 1 sequentially feeds out the rotor cores. Then, the detection and flipping device 2 sequentially detects the rotor cores and flips over any rotor cores with incorrect orientation. The detected rotor cores are then sent to the first distribution device 3. Based on the detection results, the first distribution device 3 sends qualified rotor cores to the shaping device 4 for shaping, while unqualified rotor cores are sent out. The shaped rotor cores are then sent to the pressing and detection device 6 to install plugs and check if the plugs are properly pressed in. Then, the second distribution device 72 sends the plug-in rotor cores to the discharge device 8, while unqualified rotor cores are sent out. This achieves fully automated plug pressing. Throughout the process, the operator only needs to feed and remove unqualified rotor cores, allowing one operator to monitor multiple machines simultaneously, greatly reducing the number of operators required. Furthermore, the plugs are detected before pressing in to ensure that the rotor core dimensions match the plugs, and that the rotor core orientation is accurate, reducing errors and improving overall accuracy. The shaping device 4 also performs preliminary shaping, which reduces the workload of subsequent shaping and ensures the consistency of the rotor core after shaping.

[0034] like Figures 1 to 4As shown, the rotor feeding device 1 includes a rotor feeding device 11, a rotor moving device 13, a rotor pushing device 14, and a rotor conveying device 15.

The first pushing plate 143 is fixed at the feed end of the first belt conveyor 151, and the first pushing cylinder 142 is used to push the rotor core on the first pushing plate 143 onto the first belt conveyor 151. The first belt conveyor 151 drives the rotor cores to be arranged in a row through the guide plate 152 and abut against the first baffle plate 153. The first sensor 154 detects whether there are rotor cores at the first baffle plate 153 so as to give a control signal.

[0036] like Figure 6As shown, the detection and flipping device 2 includes a first linear module 21, a first material gripping and flipping device 22, a first material gripping device 23, and a first detection device 24.

The rotor core is inserted into the first detection rod 245 and rests on the first detection seat 246. The first detection camera 242 is used to detect whether the inner diameter and outer diameter of the rotor core and the orientation of the rotor core hole are correct. The first finger cylinder 25 moves the rotor core from the first belt conveyor 151 to above the first detection rod 245. Then, the first lifting cylinder 281 lowers the rotor core, inserting its center hole into the first detection rod 245 and abutting the top of the first detection seat 246. The first detection rod 245 prevents the rotor core from tipping over or detaching from the first detection seat 246, improving the stability and reliability of the rotor core during detection. The first detection camera 242 takes a picture for detection. If the rotor core is oriented incorrectly, the first finger cylinder 25 clamps the rotor core, the first lifting cylinder 281 raises the rotor core, and then the first tilting cylinder 221 is activated, rotating the rotor core 180° to tilt it so that the desired end of the rotor core faces upwards.
