Technical Field

[0002] In motor stator production, the shaping of the first and last wires and the pre-clamping of terminals are two key processes to ensure the stability of automated production and the reliability of the final product. After stator winding, the first and last wires are usually in a free-hanging state, and their position and shape are highly uncertain. Therefore, subsequent processes, such as terminal pre-clamping, face significant challenges. Preliminary pre-clamping of terminals before stator pressing is of great importance to prevent false insertion and detachment, and to improve the pressing quality. However, in the currently common first and last wire shaping and terminal pre-clamping processes…

[0003] Semi-automatic equipment is typically used, resulting in low production efficiency. Furthermore, the shaping and inspection of the first and last lines, as well as the pre-clamping and inspection of terminals, are all completed using different machines or testing instruments.

The machine base is provided with a first clamping position, a flipping position, a second clamping position, a shaping position, and a detection position. The flipping position is located between the first and second clamping positions. The stator core 300 is transported to the first clamping position by the first conveying assembly 120, clamped by the first handling assembly 130, and transported to the flipping position. The flipping assembly 140 is located at the flipping position and is used to flip the stator core 300 180 degrees. The flipped stator core... The stator core 300 is transported to the second clamping position by the first transport assembly 130; the shaping assembly 150 includes a shaping slide 151 and a shaping mechanism 152. The shaping mechanism 152 is located at the shaping position. After the shaping slide 151 carrying the stator core 300 slides from the second clamping position to the shaping position, the stator core 300 completes the shaping of the first and last lines through the shaping mechanism 152. After the shaping is completed, the stator core 300 slides back to the detection position through the shaping slide 151, is detected by the CDD detection assembly, slides back to the second clamping position, is then transported back to the first clamping position by the first transport assembly 130, and is then transported out by the first conveying assembly 120.

[0041] The terminal pre-clamping machine 200 includes a second machine base 210, a second conveying assembly 220, a second handling assembly 230, a turntable assembly 240, a terminal pressing and pushing mechanism 250, a terminal pressing assembly 260, and a pre-pressure detection assembly 270. The second conveying assembly 220 is integrally connected to the first conveying assembly 120 to receive the shaped stator core 300 transported from the first conveying assembly 120. The second machine base 210 is provided with a third clamping position and a terminal pre-clamping position. The turntable assembly 240 is provided with a fourth clamping position, a terminal pressing and pushing position, a terminal pressing position, and a pre-pressure detection position, which are sequentially spaced 90 degrees apart. The terminal pressing and pushing mechanism 250 is located beside the terminal pressing and pushing position, the terminal pressing assembly 260 is located beside the terminal pressing position, and the pre-pressure detection assembly 270 is located beside the pre-pressure detection position. The stator core 300... The stator core 300 is moved from the third clamping position to the fourth clamping position by the second transport assembly 230. The turntable assembly 240 rotates 90 degrees to transport the stator core 300 to the terminal pressing and wire pushing position. The terminal pressing and wire pushing mechanism 250 performs terminal pressing and wire pushing on the stator core 300. The turntable assembly 240 rotates 90 degrees again to transport the stator core 300 to the terminal pressing position. The terminal pressing assembly 260 performs terminal pressing on the stator core 300. The turntable assembly 240 rotates 90 degrees again to transport the stator core 300 to the pre-press detection position. The pre-press detection assembly 270 performs pre-press detection on the stator core 300. The turntable assembly 240 rotates 90 degrees again to transport the stator core 300 back to the fourth clamping position. The stator core 300 is then moved back to the third clamping position by the second transport assembly 230 and then transported out by the second conveying assembly 220.

[0042] Based on this design, in this embodiment, firstly, the first conveying component 120 of the first and last line shaping machine 100 and the second conveying component 220 of the terminal pre-clamping machine 200 are connected as a whole, so that the terminal pre-clamping machine 200 can automatically flow into the first and last line shaping machine after the first and last line shaping is completed, thereby saving the time of intermediate buffering, handling and repositioning, and truly realizing integrated production. Secondly, in the first and last line forming machine 100, a closed-loop design of sequential cyclic transport, handling, flipping, forming, inspection, handling and then transport is used to automate the first and last line forming and related inspection of the stator core 300. Thirdly, in the terminal pre-clamping machine 200, a closed-loop design of sequential cyclic transport, handling, terminal pressing and pushing, terminal pressing and inspection, handling and then transport is used to automate the terminal pre-clamping and related inspection. In particular, the 90-degree indexing rotation of the turntable assembly 240 can decompose the key process into independent stations such as terminal pressing and pushing, terminal pressing and inspection, and pre-pressure inspection on a turntable assembly 240. This not only enables parallel processing, shortens the cycle time of a single station, and greatly improves the overall production efficiency, but also has the advantages of high integration and space saving. Finally, by optimizing the layout of each component on the machine table in the first and last line shaping machine 100 and the terminal pre-clamping machine 200, not only is the process flow smoother, but space utilization is also improved, which is conducive to equipment miniaturization and reduces the occupation of production space. In summary, this first and last line shaping and terminal pre-clamping equipment can realize automated production of first and last line shaping and terminal pre-clamping without manual intervention, greatly improving production and inspection efficiency and increasing space utilization.

[0043] It should be noted that this end-line shaping and terminal pre-clamping equipment can achieve intelligent control and data interaction through various hardware and supporting control programs. The tooling changeover in the equipment has mechanical or electrical error prevention and foolproof settings. The pneumatic or electrical control in the equipment is integrated with the machine tool as a whole, which has the advantages of small footprint and convenient transportation. In addition, the machine tool is relatively narrow on one side, which facilitates maintenance and control.

[0044] Please see Figures 1 to 3In this embodiment, the first conveying component 120 includes a first conveying track 121 and a first tray 122. The first and last line forming machine 100 also includes a first barcode scanning component 170 located beside the first conveying track 121. After the stator core 300 is positioned on the first tray 122 and transported to the first clamping position on the first conveying track 121, the first barcode scanning component 170 scans the stator core 300. Here, the stator core 300 is automatically transported to the first clamping position by the first conveying component 120, realizing the automatic positioning of the stator core 300. When the stator core 300 stops here, the first barcode scanning component 170 automatically scans the QR code information on the stator core 300, thereby achieving data traceability, process recording, and prevention of missed processes. Specifically, in this embodiment, the first conveying component 120 is preferably a double-speed chain conveyor structure to achieve continuous flow and precise stopping, and has high positioning accuracy without damaging the workpiece. However, in this embodiment, other suitable transmission devices may also be used.

[0045] Specifically, the first conveying assembly 130 includes a first horizontal moving slide bar 131, a first vertical moving slide bar 132, and a first gripper 133. The gripper is mounted on the first vertical moving slide bar 132 to drive the first gripper 133 to move up and down. The first vertical moving slide bar 132 is slidably connected to the first horizontal moving slide bar 131, and is driven to move horizontally on the first horizontal moving slide bar 131. In this way, the first gripper 133 can achieve linear movement in both the horizontal and vertical directions, thereby ensuring that after the first gripper 133 grips the stator core 300, it can accurately move back and forth between the first gripping position and the second gripping position.

[0046] Furthermore, the shaping assembly 150 also includes a shaping slide rail 153, on which the shaping slide table 151 slides; the running direction of the first conveying assembly 130 is perpendicular to the running direction of the first conveying assembly 120, and the length direction of the first horizontal moving slide rod 131 is perpendicular to the first conveying track 121; one end of the first horizontal moving slide rod 131 crosses the first conveying track 121, and the other end extends beyond the shaping slide rail 153; the length extension of the shaping slide rail 153 is consistent with the length extension direction of the first conveying track 121, and the shaping mechanism 152 is located on the side of the shaping slide rail 153 away from the first horizontal moving slide rod 131. Specifically, the shaping slide table 151 has multiple positions, and the position near the first horizontal moving slide rod 131 is the second clamping position. After the flipped stator core 300 is placed in this position on the shaping slide table 151, it can be controlled to slide on the shaping slide rail 153 to the shaping position on the other side.

[0047] Please see Figures 1 to 3In this embodiment, the flipping assembly 140 is located between the shaping slide rail 153 and the first conveying track 121. The flipping assembly 140 includes a flipping bracket 141, a flipping drive, and a flipping gripper 142. The lower end of the flipping bracket 141 is fixed to the first machine base 110. The flipping drive is mounted on the flipping bracket 141, and the flipping gripper 142 is connected to the flipping drive. The flipping drive drives the flipping gripper 142 to grip the stator core 300 and achieve a 180-degree flip. Specifically, the flipping gripper 142 is positioned with its opening facing the first horizontal moving slide bar 131, and can grip the stator core 300 located in the flipping position. Then, it is controlled to flip 180 degrees so that the side of the stator core 300 with the start and end lines faces upward, which facilitates the subsequent shaping process.

[0048] Please see Figures 1 to 3 In this embodiment, the shaping mechanism 152 includes a shaping bracket 154, a shaping drive, a shaping pressure head 155, a pressure detection component, and a displacement monitoring component. The shaping bracket 154 is located on the side of the shaping slide rail 153 away from the first horizontal moving slide rod 131, and its lower end is fixedly connected to the machine base. The shaping drive is mounted on the shaping bracket 154, and the shaping pressure head 155 is located above the shaping position on the shaping slide rail 153. The shaping pressure head 155 is driven downward by the shaping drive to achieve the shaping treatment of the first and last lines of the stator core 300. Here, by setting the pressure detection component and the displacement monitoring component, real-time detection of pressure and displacement can be achieved in the first and last line shaping process, thereby ensuring the shaping quality.

[0049] Please see Figures 1 to 3 In this embodiment, the detection position is located between the second clamping position and the shaping position; the CCD detection component 160 is disposed between the first horizontal moving slide bar 131 and the shaping mechanism 152, and is located on the side of the shaping slide rail 153 away from the flipping component 140. Here, the CCD detection component 160 includes a CCD camera, and the detection frame of the CCD camera is vertically distributed on the side of the shaping slide rail 153. When the shaped stator core 300 reaches the detection position, the shaping slide 151 automatically rotates 4 times, 90 degrees each time, and the CCD camera automatically takes pictures to detect whether the bridge line is qualified.

[0050] In addition, the first and last line shaping machine 100 also includes an inspection machine sub-assembly 180. The inspection machine sub-assembly 180 is located on the side of the shaping slide rail 153 away from the flipping assembly 140, and is situated between the first horizontal moving slide bar 131 and the CCD detection assembly 160. The first vertical moving slide bar 132 and the first gripper 133 can move on the first horizontal moving slide bar 131 to above the inspection machine sub-assembly 180. Here, the inspection machine sub-assembly 180 is mainly used to realize the automatic inspection of the CCD detection assembly 160 upon startup.

[0051] Please see Figures 4 to 6In this embodiment, for the terminal pre-clamping machine 200, the second conveying assembly 220 includes a second conveying track 221 and a second tray 222; the second handling assembly 230 includes a second horizontal moving slide bar 231, a second vertical moving slide bar 232 slidably connected to the second horizontal moving slide bar 231, and a second gripper 233 mounted on the second vertical moving slide bar 232; the length extension direction of the second horizontal moving slide bar 231 is perpendicular to the length extension direction of the second conveying track 221; one end of the second horizontal moving slide bar 231 crosses the second conveying track 221, and the other end extends to the adjacent turntable assembly 240. Here, the second conveying assembly 220 can realize the automatic positioning of the stator core 300, and is preferably a double-speed chain structure. The perpendicular layout design of the second conveying track 221 and the second horizontal moving slide bar 231 is beneficial to improve space utilization and the handling route is shorter.

[0052] In addition, the terminal pre-clamping machine 200 also includes a second scanning component 280, a third conveying component 291, and an NG component 292. The third clamping position is located between the second conveying component 220 and the third conveying component 291. The second scanning component 280 is located on the side of the second conveying track 221 away from the turntable component 240 and corresponds to the third clamping position. The third conveying component 291 includes a third horizontal moving slide bar, a third vertical moving slide bar slidably connected to the third horizontal moving slide bar, and a third gripper mounted on the third vertical moving slide bar. The third conveying component 291 and the second conveying component 230 are arranged in parallel at intervals along the running direction of the second conveying track 221. The NG component 292 is located between the second conveying track 221 and the turntable component 240 and is located on the side of the third conveying component 291 away from the second conveying component 230. It is understandable that when the stator core 300 is transported to the third clamping position, the second scanning component 280 will automatically scan the QR code on the stator core 300, thereby achieving data traceability, process recording, and prevention of missed processes. Of course, there is also an NG unloading position located next to the third handling component 291 on the second conveying track 221. If the stator core 300 is detected as unqualified, it is first transported from the fourth clamping position to the third clamping position by the second handling component 230. Then, the unqualified stator core 300 continues to be transported along the transport direction on the second pallet 222 to the NG unloading position, where it stops. Then, the third gripper grabs the unqualified stator core 300 here and transports it to the NG component 292. Finally, it is transported out through the NG component 292. In this way, the automated sorting of good and bad products can be achieved.

[0053] Please see Figures 4 to 6In this embodiment, the turntable assembly 240 includes an annular turntable 241, a turntable drive, a turntable platform 242, and a rotary lifting mechanism 243; the fourth clamping position is located on the annular turntable 241 on the side adjacent to the third clamping position, the terminal pressing position is opposite to the fourth clamping position and located on the other side of the annular turntable 241 away from the third clamping position, and the terminal pushing position and the pre-pressing detection position are respectively located on the left and right sides of the line connecting the fourth clamping position and the terminal pressing position. A turntable platform 242 is mounted on an annular turntable 241. A turntable drive unit is located below the annular turntable 241. The turntable drive unit controls the rotation of the annular turntable 241 by 90 degrees each time, so that the turntable platform 242, which is positioned and loaded with the stator core 300, is sequentially cyclically in the fourth clamping position, the terminal push position, the terminal pressing position, and the pre-pressing detection position. A turntable fixture is provided on the turntable platform 242 to position and fix the stator core 300. A rotary lifting mechanism 243 is located below the turntable platform 242 at the terminal push position to rotate and lift the turntable fixture to a predetermined position at the terminal push position. It can be understood that this design, which decomposes the process into four independent workstations by rotating the annular turntable 241 in 90-degree increments, not only enables parallel processing and shortens the cycle time of a single workstation, significantly improving overall production efficiency, but is also an integrated design that improves space utilization. Specifically, in this embodiment, the annular turntable 241 rotates clockwise. Of course, in other embodiments, the rotation sequence can also be counterclockwise.

[0054] Please see Figures 4 to 6 In this embodiment, the terminal pressing and pushing mechanism 250 includes a terminal pressing assembly 251 and a pushing assembly 252. The terminal pressing assembly 251 is located outside the terminal pressing and pushing position of the annular turntable 241, and the pushing assembly 252 is located inside the terminal pressing and pushing position of the annular turntable 241. The pushing assembly 252 is used to push the first and last wires of the stator core 300 into the terminal, and the terminal pressing assembly 251 is used to flatten the terminal with the first and last wires pushed in. Here, the pushing assembly 252 located inside can push the first and last wires into the terminal before pressing the terminal, thereby preventing false insertion and ensuring that the wire ends do not fall off during transportation.

[0055] Please see Figures 4 to 6In this embodiment, the terminal pressing assembly 260 includes a terminal pressing bracket, a terminal pressing drive, and a terminal pressing head. The terminal pressing bracket is located outside the terminal pressing position of the annular turntable 241. The terminal pressing drive is mounted on the terminal pressing bracket, and the terminal pressing head is located directly above the terminal pressing position of the annular turntable 241. The terminal pressing drive drives the terminal pressing head downward to flatten all the terminals of the stator core 300. Here, the terminal pressing bracket acts as a rigid base, providing stable mechanical support and effectively preventing shaking during pressing. The terminal pressing drive can be, but is not limited to, a servo motor or a high-precision cylinder, providing controllable downward pressure and stroke to ensure consistent pressing force and depth each time. The terminal pressing head, located directly above the terminal pressing position, can be designed as a flat pressing block or a multi-contact claw, capable of simultaneously contacting all terminals to flatten them all at once.

[0056] Please see Figures 4 to 6 In this embodiment, the pre-pressure detection component 270 includes a pre-pressure detection bracket 271 and a pre-pressure detection camera 272. The pre-pressure detection bracket 271 is located outside the pre-pressure detection position of the annular turntable 241, and the pre-pressure detection camera 272 is installed on the upper end of the pre-pressure detection bracket 271, and is located directly above the turntable platform 242 at the pre-pressure detection position. Specifically, the pre-pressure detection camera 272 mainly serves to take pictures to detect whether the pressing is qualified. If the detection is qualified, the stator core 300 will be rotated to the fourth clamping position, and then transported to the third clamping position on the second transport component by the second handling component 230, and then transported to the next process by the second transport component.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
