Therefore, they should not be understood as limitations on this application.

[0043] In addition, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] It should be further understood that the term “and / or” used in this specification and the corresponding claims refers to any and all possible combinations of one or more of the listed items.

[0045] Example 1:

[0046] A non-return unlocking device, referring to Figures 1 to 3 , including a docking trolley 1 and a frame 3, the frame 3 has a defective product station 31, when the motor controller 10 (product) that fails the inspection is transported to the defective product station 31, the docking trolley 1 is moved to the defective product station 31 to turn over the unqualified products.

[0047] In this embodiment, the docking trolley 1 is moved to the defective product station 31 by being pushed. A handle 30 is provided on the docking trolley 1 to facilitate the operator to push the docking trolley 1 .

[0048] The docking trolley 1 is also equipped with universal wheels at the bottom, and the two sets of universal wheels near the handle 30 have locking parts that can be turned to lock or unlock the universal wheels. When the docking trolley 1 is moved to the defective product station 31, the universal wheels are locked to reduce the possibility of the docking trolley 1 moving when the motor controller 10 is turned.

[0049] Further, refer to Figure 1 A non-return structure 2 is provided at the starting end of the connecting trolley 1. The non-return structure 2 keeps the product flow smooth when the product is transported from the defective product station 31 to the connecting trolley 1, limits the product when it enters the connecting trolley 1, and reduces the possibility of the product sliding from the starting end of the connecting trolley 1 during the process of pushing the connecting trolley 1.

[0050] It should be noted that, in this embodiment, when the product is transported on the production line 9 and between the frame 3 and the docking trolley 1, a pallet 20 is provided to support and transfer the product, and the non-return structure 2 constrains the product by limiting the pallet 20.

[0051] Combine Figure 4 and Figure 5 The non-return structure 2 includes a fixed support 21 and a movable stopper 22. The fixed support 21 is fixed to the docking trolley 1. The movable stopper 22 is rotatably arranged on the fixed support 21 and has a contact surface 221 at one end away from the fixed support 21. The movable stopper 22 has a first state and a second state.

[0052] When the movable stopper 22 is in the first state, its top surface is staggered with the top surface of the fixed support 21 and at least partially higher than the fixed support 21. When the movable stopper 22 is in the second state, its top surface is in the same plane as the top surface of the fixed support 21.

[0053] Specifically, when the product moves from the defective product station 31 to the docking trolley 1, the product is pressed on the movable stopper 22, causing the movable stopper 22 to rotate clockwise until its top surface is in the same plane as the top surface of the fixed support 21, so that the movable stopper 22 is in the second state, and the product passes smoothly and is finally on the docking trolley 1.

[0054] When the movable stopper 22 is not subjected to external force, one end of the movable stopper 22 having the contact surface 221 naturally tilts downward, so that the top surface of the movable stopper 22 and the top surface of the fixed support 21 are staggered, and the end of the movable stopper 22 away from the contact surface 221 naturally tilts upward and is higher than the fixed support 21, so that the movable stopper 22 is in a first state. In the first state, if the product is already on the docking trolley 1, the upwardly tilted end of the movable stopper 22 limits the product.

[0055] Correspondingly, in one embodiment, an elastic member (specifically a spring) can be provided between the movable stopper 22 and the fixed support 21, with one end of the elastic member connected to the movable stopper 22 and the other end of the elastic member connected to the fixed support 21; when a product is pressed above the movable stopper 22 so that it is in the second state, the elastic member is squeezed or stretched, and after the product above the movable stopper 22 passes, the elastic member resets to restore the movable stopper 22 to the first state.

[0056] In this embodiment, referring to Figure 2 and Figure 4 A support plate 5 is provided at the starting end of the docking trolley 1. When the movable block is in the first state, the contact surface 221 is against the top surface of the support plate 5. The movable stopper 22 is supported by the support plate 5 to maintain the movable stopper 22 in the first state under normal conditions, thereby achieving the purpose of limiting the product. Compared with the method of using elastic parts, the pressure of the movable stopper 22 on the product in the second state can be reduced.

[0057] The movable stopper 22 can better restrain the product to reduce the possibility of the product sliding off the starting end of the docking trolley 1 .

[0058] On this basis, a limit block 8 is set on the side of the docking trolley 1 away from the starting end, and the limit block 8 cooperates with the movable block 22 in the first state to clamp the motor controller 10. The limit block 8 blocks the far end of the docking trolley 1 to further limit the product.

[0059] Further, refer to Figure 3 Furthermore, a pair of guide structures 7 are provided at the starting end of the docking trolley 1. The pair of guide structures 7 are symmetrically arranged on both sides of the docking trolley 1. The guide structure 7 includes a guide bar 72 and a plurality of guide wheels 71. The two pairs of guide bars 72 are fixed on the docking trolley 1 and are spaced to form a guide space to provide a guiding effect when the product is transported from the defective product station 31 to the docking trolley 1; the plurality of guide wheels 71 are arranged in sequence along the length direction of the docking trolley 1 to reduce the movement resistance of the product during its movement, so that the product can be more smoothly transferred to the docking trolley 1.

[0060] Combine Figure 4 and Figure 5The non-return unlocking device also includes an unlocking structure 4, which is arranged at the terminal end of the frame 3 and has an inclined wedge surface 41 that cooperates with the contact surface 221. When the docking trolley 1 is docked with the frame 3, the unlocking structure 4 pushes the movable block 22 to rotate from the first state to the second state through the inclined wedge surface 41.

[0061] Specifically, when the docking trolley 1 is docked to the frame 3, the contact surface 221 of the movable stopper 22 contacts the inclined wedge surface 41 of the unlocking structure 4. Under the push of the inclined wedge surface 41, the contact surface 221 of the movable stopper 22 and the inclined wedge surface 41 are finally completely fitted together. At this time, the movable stopper 22 is in the second state, and the docking trolley 1 moves into place.

[0062] In order to make the docking trolley 1 able to connect smoothly with the frame 3, refer to Figure 2 A pair of limiting structures 6 are provided at the terminal end of the frame 3. The limiting structures 6 are spaced apart and form a limiting space for the docking trolley 1 to enter. When the docking trolley 1 is moved, the posture of the docking trolley 1 is adjusted to align with the limiting space so that the docking trolley 1 can dock with the frame 3 accurately.

[0063] On this basis, a detection member can be further provided to detect whether the docking trolley 1 is properly docked with the frame 3. This application does not limit the specific form of the detection member. For example, the detection member can be provided as a displacement sensor, which determines that the docking is in place when the docking trolley 1 moves a specified distance after entering the confined space; or the detection member can be provided as a pressure sensor, which determines that the docking is in place when the docking trolley 1 abuts against the frame 3.

[0064] Furthermore, the width of the beveled wedge surface 41 is 1 to 5 times the width of the contact surface 221. By providing a beveled wedge surface 41 that is wider than the contact surface 221, it is ensured that when the docking trolley 1 is docked with the frame 3, the contact surface 221 can smoothly cooperate with the beveled wedge surface 41, allowing the movable block 22 to smoothly switch from the first state to the second state. The width of the beveled wedge surface 41 is specifically set according to actual conditions and can be 2 times, 3 times, 4 times, etc. the width of the contact surface 221. In this embodiment, the width of the beveled wedge surface 41 is set to 3 times the width of the contact surface 221.

[0065] In addition, in this embodiment, multiple groups of non-return structures 2 and unlocking structures 4 are provided, and multiple groups of non-return structures 2 and multiple groups of unlocking structures 4 are provided in a one-to-one correspondence. The multiple groups of non-return structures 2 can better limit the product at the starting end of the docking trolley 1.

[0068] S1, push the product from the defective product station 31 to the docking trolley 1;

[0069] S2. Unlock the docking trolley 1 and move it to the next unit. During the movement, the movable block 22 is always in the first state and limits the product.

[0070] S3. After the product inspection is completed, the mobile docking trolley 1 returns to the frame 3;

[0071] S4, move the docking trolley 1 to the frame 3, and when the movable block 22 is pushed to the second state by the unlocking structure 4, position the docking trolley;

[0072] S5. Push the product from the docking trolley 1 to the rack 3.
