Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a stator segment feeding and forming production line. Background Art

[0002] The motor is one of the core components of the drive system. The stator is the stationary part of the motor or generator, usually consisting of three parts: the stator core, the stator winding, and the frame. The stator core is stacked by multiple annular stator segments of the same specification. Many manufacturers use the segment blanking process for the stator punching sheets of generators or motors. To make a complete stator, it is necessary to stack the segments around the center to form a circle. Since the small holes in the product are staggered, each section is composed of stator segments of different specifications and quantities during stacking. Then, after misalignment, the second section is stacked, and so on, until a complete stator is formed. In the prior art, this stacking process is carried out manually, generally by multiple people working together, which is prone to material mixing, poor accuracy, time-consuming and laborious, and has a high scrap rate. Summary of the Invention

[0021] The present utility model will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.

[0022] As Figure 1A stator sheet feeding and forming production line as shown includes a station intelligent feeding bin A, which includes several sub-bins 1. Different specifications of products are placed in each sub-bin 1. Among them, the station intelligent feeding bin A is a rotary bin. The station intelligent feeding bin A includes a tray. A number of sub-bins 1 are arranged in an annular array on the tray. The number of sub-bins 1 is set according to product requirements. Different specifications of stator sheets are placed in each sub-bin 1. A thickness measuring device and a weighing device are provided on any one of the sub-bins 1. Both the thickness measuring device and the weighing device are connected to a display screen installed on the sub-bin 1. Workers are located in front of the display screen to manually detect and confirm the segmented bodies, thereby preventing material mixing through the cooperation of manual labor and devices.

[0023] A double-station alternating detection segmented feeding table B is located on one side of the station intelligent feeding bin A. It includes a feeding rack 5. A number of feeding groups are installed on the feeding rack 5. Each feeding group contains more than one feeding station. Feeding is alternated between each feeding group. For example, there are two feeding groups, and each feeding group has two feeding stations. A vision detection device 6 for detecting products on the feeding group is also installed on the feeding rack 5. That is to say, each feeding station corresponds to a vision detection device 6. The vision detection device 6 is arranged away from the station intelligent feeding bin A to re-detect each segmented section to prevent material mixing.

[0024] A six-axis assisting robot feeding device C is used to grab the segmented bodies on the double-station alternating detection segmented feeding table B and send them to the next process.

[0025] A chain plate line feeding device D includes a conveying device and is installed on a tooling plate 2 on the conveying device. A finished product outer diameter detection station 3 is installed at the output end of the conveying device.

[0026] A handling truss E is used to integrally handle the qualified formed products on the finished product outer diameter detection station 3 to the next station.

[0027] A welding device F welds the formed products. Among them, a defective product placement table 4 is provided between the chain plate line feeding device D and the welding device F. The output end of the chain plate line feeding device D is placed with the welding device F. The handling truss E is located at the junction of the chain plate line feeding device D and the welding device F.

[0028] In addition, it also includes a control unit (not shown in the figure) for controlling the operation of this production line. At the same time, before processing, the information of the stator to be produced is input to compare with the detection information of each station.

[0029] Working process:

[0030] Step 1: Manually load the 5 types of products required (specifically depending on product requirements) into each bin 1 until it is full. Take materials in segments according to the requirements of the assembled stator, compare with the preset values in the program. After passing the comparison, a green light will be on.

[0031] Step 2: The multi-station intelligent feeding bin A automatically feeds according to the program settings. Rotate bin 1 to the manual position. Automatically calculate the weight and thickness of the products taken by the weighing device and thickness measuring device. After reaching the required values, the worker removes the products, and it shows that the material taking is completed. Otherwise, it will prompt the worker to operate.

[0032] Step 3: Manually place the segmented products into one of the feeding stations of the rear feeding group of the double-station alternating detection segmented feeding table B according to the program settings.

[0033] If after the feeding of one feeding station in this feeding group is completed, the product on the corresponding other feeding group has not been grabbed by the six-axis assisting robot feeding device C and placed into the next station, then place it into the other feeding station of this feeding group.

[0034] Step 4: After placing the segmented products, this feeding station automatically moves to the vision inspection position for inspections such as oil grooves and special-shaped grooves. After the inspection is completed and confirmed to be correct, the six-axis assisting robot feeding device C takes this segmented product and places it into the tooling plate 2 on the chain plate line feeding device D.

[0035] Step 5: After the vision inspection device 6 completes the inspection and confirms it is correct, the double-station alternating detection segmented feeding table B automatically ejects to allow the worker to place the next segment of products. After placing, it automatically moves to the vision inspection position to complete the inspection.

[0036] Step 6: After the inspection at the vision inspection position is completed, the multi-station intelligent feeding bin A automatically ejects to allow the worker to place the next segment of products.

[0037] If there is a problem with the inspection, do not feed the next segment of products. The current station ejects and prompts the worker with the specific cause of nonconformance. After manual processing and placing, click the button to continue the operation.

[0038] Step 7: The six-axis assisting robot feeding device 6 places the segmented products with qualified vision inspection, thickness inspection, and quantity into the tooling plate 2 of the chain plate line feeding device D. According to the program design (required for each completed product), until the placement of each product segment is completed, forming a completed product.

[0039] Step 8: The chain plate line feeding device D automatically transports the completed product to the outer diameter inspection station G before feeding the finished product, and automatically completes the final re-inspection before feeding. This inspection area will detect whether the marking groove on the side is correct. This inspection uses a 3D scanning camera for scanning and forming, and compares with the preset values. After being consistent, it is transported to the next process.

[0040] Step 9: The handling truss E transports the qualified finished products as a whole to the laser welding waiting position of the welding equipment F and waits for welding; if there are defective products, they will be placed at the defective product placement table 4, and so on.

[0041] Inspired by the ideal embodiments of the present utility model described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
