DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] like Figures 1 to 7 As shown, the scrap rejection and unloading mechanism described in this embodiment is used to reject stators 100 that fail the electrical performance test. The mechanism mainly includes: a rotating turntable 20 mounted on the frame 10, a lifting and unloading mechanism 30 located below the turntable 20, a transfer mechanism 40 for transferring the stators, and a scrap rejection channel 50 located next to the turntable 20.

[0026] The turntable 20 is equipped with multiple positioning slots spaced evenly around its circumference. Each slot houses a stator test socket 60, topped with an electrical connection pin 70 for connecting to the lead pins of the stator 100 under test. Before testing, the stator 100 is placed in the positioning slots, its lead pins secured to the electrical connection pins 70 by a robotic arm or manually, and then connected to external testing equipment (not shown) for electrical performance testing.

[0027] After the test is completed, regardless of the test results, the ejection mechanism 30 (e.g., pneumatically or electrically driven) ejects the stator 100 from the electrical connection pin 70. For stators 100 that fail the test, the clamp 43 of the transfer mechanism 40 immediately and accurately clamps them. The clamp 43 can move horizontally and vertically, first moving the stator 100 horizontally to above the waste rejection channel 50, and then moving vertically downward to send the stator 100 into the waste rejection channel 50. The design of the waste rejection channel 50 (e.g., with an inclined material plate and side guards) ensures that unqualified stators 100 are discharged smoothly and prevents accidental damage to qualified stators.

[0028] In a preferred embodiment, the entire process is automated by a PLC control system (not shown), enabling continuous and efficient stator testing and rejection. The rotation of turntable 20 ensures continuous testing and rejection of stators 100, significantly improving efficiency and surpassing traditional manual or single-arm operation methods.

[0029] In some embodiments, as Figure 3 As shown, the turntable 20 includes a disk body 21 , a plurality of mounting slots 22 equidistantly spaced along the circumference of the disk body 21 , and a positioning plate 23 detachably mounted in the mounting slots 22 , wherein the positioning slots are formed on the positioning plate 23 .

[0030] The turntable 20 of this embodiment adopts a modular design, which facilitates maintenance and replacement and can accommodate stators 100 of different specifications. Specifically, the turntable 20 has a plurality of mounting slots 22 equidistantly arranged around its body 21. Each slot accommodates a removable positioning plate 23. Each positioning plate 23 is provided with a positioning groove that matches a stator 100 of a specific size, ensuring precise positioning of the stator 100. If a single positioning plate 23 is damaged, only that positioning plate 23 needs to be replaced, without having to replace the entire turntable 20, thus reducing maintenance costs. Furthermore, when faced with stators 100 of different specifications, only the positioning plate 23 of the corresponding size needs to be replaced, without having to redesign or manufacture the entire turntable 20, thereby reducing production costs and increasing flexibility.

[0031] In some embodiments, as Figure 3 As shown, a buffer rubber pad 24 is provided on the inner wall surface of the positioning groove. The buffer rubber pad 24 is made of elastic material, such as silica gel or rubber, so as to effectively absorb impact force, protect the stator 100 from damage, and reduce noise.

[0032] In some embodiments, as Figure 1 、 Figure 2 As shown, the transfer mechanism 40 includes an X-axis moving mechanism 41 and a Z-axis lifting mechanism 42, the clamp 43 is a finger cylinder arranged at the power output end of the Z-axis lifting mechanism 42, and the Z-axis lifting mechanism 42 is arranged at the power output end of the X-axis moving mechanism 41.

[0033] In this embodiment, the X-axis moving mechanism 41 is a linear slider guide or a screw nut guide, and the Z-axis lifting mechanism 42 is a screw lifting structure, an electric lifting structure or a cylinder lifting structure.

[0034] Using this structural design, the clamp 43 is installed at the power output end of the Z-axis lifting mechanism 42, and serves as an actuator to clamp and move the unqualified stator 100. Specifically, the Z-axis lifting mechanism 42 is installed at the power output end of the X-axis moving mechanism 41. The X-axis moving mechanism 41 controls the horizontal movement of the clamp 43 to move the clamped unqualified stator 100 to the top of the waste rejection channel 50. The Z-axis lifting mechanism 42 controls the vertical movement of the clamp 43 to send the unqualified stator 100 into the waste rejection channel 50. This coordinated control of the XZ axes enables the clamp 43 to accurately position and operate the stator 100, thereby realizing an efficient and reliable rejection process.

[0035] In some embodiments, as Figure 1 As shown, the waste rejection channel 50 includes an inclined material plate 51 and guard plates 52 arranged on both sides of the material plate 51. The distance between the guard plates 52 is adapted to the width of a single stator 100. The guard plates 52 are provided with a beam sensor 53 on the side near the feed end of the material plate 51. In this way, the material plate 51 is tilted, and the stators 100 are automatically discharged by their own gravity, while the guard plates 52 on both sides prevent the stators 100 from scattering, ensuring the cleanliness and safety of the material channel 50. In addition, a photoelectric sensor 53 is installed at the feed end of the material plate 51 to monitor the discharge of unqualified stators 100 in real time. When the accumulation of unqualified stators 100 on the material plate 51 exceeds a preset number, the sensor 53 triggers an alarm, prompting staff to clean it up in time, avoiding blockage in the material channel and ensuring the continued stable operation of the system.

[0036] In some embodiments, as Figures 4 to 7 As shown, a terminal 61 for connecting an external electrical performance test device is embedded on the side of the stator test socket 60, and the electrical connection pin 70 is electrically connected to the terminal 61; a pad 62 is provided on the top of the stator test socket 60, and the pad 62 is provided with a guide sliding hole adapted to the electrical connection pin 70, and a tension spring 63 is fixedly connected to the side of the pad 62 facing the stator test socket 60; a countersunk hole 64 for accommodating the tension spring 63 is provided on the top of the stator test socket 60, and the side of the tension spring 63 facing away from the pad 62 is fixed to the bottom of the countersunk hole 64; a push rod 65 is provided at the bottom of the pad 62, and the lower end of the push rod 65 extends to below the table of the turntable 20, and the cylinder 90 is a cylinder arranged below the turntable 20 and coaxially arranged with the push rod 65.

[0037] During the test, under the action of the tension spring 63, the spacer 62 presses the stator test socket 60, exposing the electrical connection pin 70. Then, the stator lead head is aligned and inserted into the electrical connection pin 70 on the spacer 62, so that the electrical connection pin 70 is in close contact with the stator lead head, establishing a reliable electrical connection. Next, the stator is subjected to an electrical performance test through an external test device connected to the terminal 61. When the test is completed, the cylinder 90 extends until the spacer 62 overcomes the preload of the tension spring 63, separates from the stator test socket 60, and drives the stator lead head to completely detach from the electrical connection pin 70. Finally, the cylinder 90 is controlled to retract, so that the push rod 80 and the spacer 62 are reset under the action of the tension spring 63, ready for the next test. The entire process is completed automatically, improving test efficiency and reliability.

[0038] In some embodiments, as Figure 6 As shown, the stator test socket 60 includes a first portion 60a and a second portion 60b stacked one above the other. A groove 60c is provided on the side of the second portion 60b facing the first portion 60a. The terminal 61 is embedded in the second portion 60b and at least partially placed in the groove 60c. The electrical connection pin 70 is fixed to the first portion 60a, and the electrical connection pin 70 is at least partially placed in the groove 60c.

[0039] With this structural design, first, the groove 60c provides a space for accommodating the wiring harness of the connection terminal 61 and the electrical connection pin 70, making the internal wiring more regular and avoiding exposure of the wiring harness. At the same time, it also protects the wiring harness from external damage, thereby improving the reliability and safety of the connection; secondly, the modular design of dividing the stator test socket 60 into an independent first part 60a and a second part 60b greatly simplifies the maintenance and replacement process. Whether the terminal 61 or the electrical connection pin 70 fails, or a different model of terminal 61 needs to be replaced to adapt to different test equipment, it is only necessary to replace the corresponding parts, without disassembling or replacing the entire stator test socket 60, thereby significantly reducing maintenance costs and time and improving equipment maintenance efficiency.

[0040] In some embodiments, as Figure 6As shown, the electrical connection pin 70 is covered with an insulating sleeve (not shown in the figure), and the top of the electrical connection pin 70 is at least partially exposed outside the insulating sleeve; the aperture of the guide slide hole is adapted to the diameter of the insulating sleeve. In this way, the insulating sleeve can not only effectively isolate the electrical connection pin 70 from other conductive components, ensuring the safety of operators and equipment, but also protect the electrical connection pin 70 from damage such as wear, corrosion and oxidation, especially in the case of frequent plug-in and unplug tests, effectively extending its service life. In this embodiment, preferably, the insulating sleeve is made of a brightly colored insulating material, such as red or yellow, so as to clearly mark the position of the electrical connection pin 70, facilitate the operator to quickly and accurately perform connection and disconnection operations, and improve the safety of the operation.

[0041] The waste rejection and unloading mechanism provided in this embodiment has a simple structure, is easy to maintain, has high safety, and has a wide range of applications. It effectively rejects stators that fail electrical performance tests, significantly improves production efficiency, reduces production costs, and effectively ensures product quality.
