Description

Technical Field

[0001] The utility model relates to a conveying system, in particular to a conveying system for producing flat wire motors and a flat wire motor production system adopting the conveying system. Background Art

[0002] The flat wire motor stator production process includes multiple different links and is more complex than that of ordinary motors. Therefore, the production process involves more processing steps, and different processing steps need to be performed at different processing stations. Therefore, the flat wire motor stator must be transported and moved multiple times before it can be sent to different processing stations for processing. Therefore, the positioning accuracy of the transport system is very high.

[0003] Existing conveying systems typically consist of conveyor belts or rollers to transport semi-finished products. A motor and control system drive the conveyor belt to transport the semi-finished products in a preset direction and speed. However, this conveying system maintains a single conveying speed and direction within the same conveyor belt section. In the production of flat wire motors, which have multiple stator component types and differing processing techniques, the efficiency of the entire conveying system is limited by the component with the longest processing time. To ensure that this component can be processed, other components must wait on the conveyor belt, reducing efficiency. Furthermore, due to the one-way nature of the conveyor belt, the layout of all processing stations must be strictly arranged according to the processing sequence. If the same processing technique needs to be performed multiple times, a corresponding number of processing stations must be installed on the production system's assembly line. This increases the cost of the production system and reduces production efficiency.

[0004] Therefore, a flexible and efficient transportation system to cooperate with the flat wire motor stator production process is a technical problem that needs to be solved urgently. Utility Model Content

[0031] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0032] Figure 1 The flat wire motor transport system is shown, comprising a ring-shaped stator track 10, a mover tray 20 mounted on the stator track 10, and a control unit (not shown). The stator track 10 comprises a main segment 101 and branch segments 102. In this embodiment, the main segment 101 is rectangular, with three branch segments located on each long side of the rectangle, for a total of six. The shape of the main segment 101 and the number of branch segments 102 can be adjusted to suit the specific requirements of the flat wire motor being produced and the location of the processing equipment. This embodiment uses a rectangular ring shape and six branch segments as an example. The stator track 10 is connected by a plurality of different segmented tracks 14. There are three types of segmented tracks 14, namely a straight segment 141, a corner segment 142 and a branch segment 143. The corner segment 142 deflects the direction of the stator track 10 by 90°. The straight segment 141 is a straight stator track segment. The branch segment 143 divides the trajectory of the stator track into two, including a straight sub-segment and a corner sub-segment. The straight sub-segment is the same as the straight segment 141, and the corner sub-segment is the same as the corner segment 142. One end of the corner sub-segment coincides with one end of the straight sub-segment to form one end of the branch segment 143, and the other end of the corner sub-segment is deflected by 90°.

[0033] Each of the branch line segments 102 includes two branch segments 143, which are led out from the main line segment 101 through one branch segment 143 and then led back to the main line segment 101 through another branch segment 143, thereby forming a complete branch segment 143. The two branch segments 143 are connected by a straight line segment 141 and a corner segment 142 to form the shape required for the flat wire motor production system. In this embodiment, a simplest branch line segment form is exemplified, that is, there is only one straight line segment 141 in the two branch segments 143.

[0034] The flat wire motor conveying system of this embodiment further includes a mover tray 20 disposed on the stator rail 10. Figure 1As shown in the figure, seven mover trays 20 are exemplarily shown, two of which are located on the trunk section 101 and are moved or stationary according to the needs of the machining process, one is located on the branch section 143 and is moving from the trunk section 101 to the branch section 102, one is located on the branch section 143 and is moving from the branch section 102 to the trunk section 101, one is stationary on a branch section 102, at this time, the parts placed on this mover tray 20 can receive machining work from the machining equipment because it is located on the branch section 102, and the other mover tray 20 can pass through the trunk section 101 without being affected by the mover tray 20 that is stationary and receiving machining. According to the actual machining needs, more mover trays 20 can be provided in this embodiment, and in general, the number of mover trays 20 is not less than the number of branch sections 102, which ensures that the machining equipment on each branch section is as much as possible to avoid idle waiting, and there are enough mover trays 20 to carry parts to be machined as standby, which not only meets the machining efficiency requirements of the flat motor, but also maximizes the interference between each other, and maximizes the efficiency of the flat motor parts transport and movement.

[0035] The trunk section 101 of the stator track 10 in this embodiment is a closed ring, and each branch section 102 also branches out and converges from the trunk section 101 to form a closed loop, so the corner section 142 and the branch section 143 that make up the stator track 10 are both even numbers. However, because each mover tray 20 is independently bidirectional, the trunk section 101 can also be open-looped according to the actual position relationship of the production equipment, and each branch section 102 can also be selected to be open-looped or closed-looped as needed, so the number of each section track 14 that makes up the stator track 10 can also be different.

[0036] Figure 2 、 Figure 3 and Figure 4 The partial section of the flat motor conveying system of this embodiment is shown from three different angles. The stator track 10 is provided with convex tracks 11 parallel to each other on both sides, and the inner side of the convex tracks 11 is provided with rows of rollers 13 for carrying the mover trays 20. The mover tray 20 is a rectangular tray with the same width as the stator track 10, and the length is less than each electromagnetic drive unit 12, which can move linearly on the stator track 10 by means of the rollers 13. The bottom of the mover tray 20 is provided with a magnetic drive part 21, and a plurality of electromagnetic drive units 12 are arranged between the convex tracks 11, each electromagnetic drive unit 12 is arranged along the stator track 10, and there is an air gap between the magnetic drive part 21 at the bottom of the mover tray 20 and the electromagnetic drive unit 12.

[0037] The flat wire motor transport system further includes a control unit (not shown). The control unit is provided with a signal interface. Each electromagnetic drive unit 12 is connected to a signal interface via a signal line. Under the control of the control unit, each electromagnetic drive unit 12 generates a directional driving force on the mover tray 20. To allow for the expansion and extension of the stator rail 10, the number of signal interfaces may be greater than the number of electromagnetic drive units 12.

[0038] Because there is no contact between the electromagnetic drive unit 12 and the magnetic drive portion 21, the mover tray 20 experiences very little frictional resistance and air resistance as it moves along the stator track 10 on the roller 13, resulting in very little additional energy consumption. Furthermore, the mover tray 20 operates passively, requiring no power cable connection, further reducing weight. It also allows for more free movement on the stator track 10, preventing cable interference and entanglement between multiple mover trays 20.

[0039] The stator track 10 is formed by connecting segmented tracks 14. Figure 2 As shown, two straight segments 141 are spliced ​​together to form a longer stator track 10. Each segmented track 14 is provided with segmented convex rails 11 of the same length on both sides. Adjacent segmented convex rails 11 are fixedly connected by bolts.

[0040] Another specific embodiment of the present invention is a flat wire motor production system with the above-mentioned conveying system, wherein a plurality of processing stations are provided along the stator track 10, each processing station corresponding to one of the branch line segments 102, and various processing equipment are provided on each processing station. Each of the processing equipment has a clamping claw for moving the parts to be processed transported to the corresponding branch line segment 102 from the mover pallet 20 to the processing equipment, or moving the processed parts to the mover pallet 20 resting on the corresponding branch line segment 102.

[0041] The processing required for flat wire motor production includes at least painting, cutting, forming, and straightening. The processing equipment in this embodiment can be equipped with two or more of these four processes. While it is possible for each processing equipment along the line to perform the same processing, the time required for different processing steps can be minimized in this production system, demonstrating a higher efficiency compared to existing flat wire motor production systems.
