Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0019] To facilitate understanding of the paper insertion depth compensation mechanism provided in this application embodiment, its application scenario is first described. The paper insertion depth compensation mechanism provided in this application embodiment is used to detect and compensate for the paper insertion depth of the motor stator. Currently, the paper insertion depth of the motor stator varies significantly during paper insertion, resulting in inconsistent lengths and large fluctuations in the length of the insulating paper exposed outside the motor stator end. Therefore, this application embodiment provides a paper insertion depth compensation mechanism to improve the paper insertion effect on the motor stator. A detailed description is provided below with reference to specific drawings and embodiments.

[0020] First refer to Figure 1 As shown, Figure 1 This diagram illustrates an application scenario of the paper insertion depth compensation mechanism provided in this embodiment. The paper insertion depth compensation mechanism provided in this embodiment is applied to a paper insertion mechanism. Figure 1 As shown, the paper insertion mechanism mainly includes a frame, a paper insertion assembly 20 mounted on the frame, and a lifting and rotating mechanism 10. The paper insertion assembly 20 and the lifting and rotating mechanism 10 are arranged vertically, forming a space to accommodate the motor stator. In use, the motor stator is supported on the lifting and rotating mechanism 10, which raises it to the paper insertion position. The paper insertion assembly 20 includes a paper feeding roller 21 and a paper feeding servo mechanism 22. The paper feeding servo mechanism 22 drives the paper feeding roller 21 to insert insulating paper into the insulating paper slots of the motor stator. During the paper insertion process, since there are multiple insulating paper slots arranged around the motor stator, the lifting and rotating mechanism 10 rotates the motor stator, allowing the insulating paper to be inserted into the slots sequentially. The aforementioned paper insertion assembly 20 and lifting and rotating mechanism 10 are conventional mechanisms in paper insertion systems and will not be described in detail here.

[0021] In addition, the paper insertion depth compensation mechanism's paper insertion detection mechanism 100 is also arranged on the frame, and the paper insertion detection mechanism 100 and the lifting and rotating mechanism 10 are located on the same side of the motor stator. That is, when the motor stator is in the paper insertion working position, the paper insertion detection mechanism 100 is located below the motor stator to detect the length of the portion of the insulating paper exposed outside the end of the motor stator.

[0022] Please refer to the above. Figure 2 As shown, Figure 2 A schematic diagram showing the cooperation between the lifting and rotating mechanism 10 and the paper insertion depth compensation mechanism is shown. Figure 2 As shown, the paper insertion compensation mechanism includes a bracket 110 and a paper insertion detection mechanism 100. The bracket 110 is used to fix the paper insertion compensation mechanism to the frame, and the bracket 110 is provided with a through hole for the lifting and rotating mechanism 10 to pass through. Part of the driving component 190 of the lifting and rotating mechanism 10 can be arranged below the bracket 110, and the support mechanism for supporting the motor stator can pass through the through hole on the bracket 110 and be exposed. The paper insertion detection mechanism 100 is located on the side of the bracket 110 facing the motor stator and is fixedly connected to the bracket 110 so that the bracket 110 can stably support the paper insertion detection mechanism 100. It should be understood that the bracket 110 provided in this application embodiment is an optional structural component. Other structural components that can provide stable support for the paper insertion detection mechanism 100 can also be applied in this application embodiment, or the paper insertion detection mechanism 100 can be arranged on a support surface, such as the ground or other structural components, without the bracket 110. For ease of description, the following description uses a paper insertion depth compensation mechanism including a bracket 110 as an example.

[0023] To facilitate the description of the paper insertion depth compensation mechanism provided in the embodiments of this application, the following will use... Figure 1 The orientation of the paper insertion mechanism shown is described with reference to the orientation.

[0024] refer to Figure 3 , Figure 4 and Figure 5 As shown, Figure 3 This paper insertion detection mechanism 100 provided in an embodiment of the present application is shown in a structural schematic diagram. Figure 4 This paper insertion detection mechanism 100 provided in an embodiment of this application is shown from another angle. Figure 5A cross-sectional view of the paper insertion detection mechanism 100 provided in this application embodiment is shown. The paper insertion detection mechanism 100 mainly includes a probe 120, a drive member 190, and a sensor 130. The probe 120 is used to press against the end of the motor stator or insulating paper, the drive member 190 is used to move the probe 120, and the sensor 130 is used to detect the position of the probe 120. For example, in use, when the probe 120 presses against the motor stator, the sensor 130 generates a first signal; when the probe 120 presses against the end of the insulating paper, the sensor 130 generates a second signal. The length of the insulating paper exposed at the end of the motor stator during paper insertion can be determined by the first and second signals. It should be understood that the aforementioned motor stator end and insulating paper end both refer to the lower end, that is, the lower end of the motor stator and insulating paper during the paper insertion process.

[0025] Specifically, when the motor stator is in the paper insertion position and the paper insertion assembly 20 is not inserted, the drive component 190 can drive the probe 120 to rise and press against the end of the motor stator (the position of the insulating paper slot). At this time, the sensor 130 can generate a first signal. When the paper insertion assembly 20 inserts paper into the insulating paper slot, as the insertion depth increases, the insulating paper begins to protrude from the end of the motor stator and abuts against the probe 120. During the insertion of the insulating paper, the end of the insulating paper pushes the probe 120 down, and the drive component 190 can keep the probe 120 in contact with the end of the insulating paper, thereby realizing the length transmission function of the amount of insulating paper exposed. After the paper insertion action is completed, the sensor 130 can generate a second signal. The length of the insulating paper exposed outside the end of the motor stator can be determined by the first signal and the second signal.

[0026] The paper insertion depth compensation mechanism also includes a data processing module. This module can determine the first length of the insulating paper exposed on the motor stator based on a first signal and a second signal. Furthermore, the data processing module can adjust the paper insertion depth of the paper insertion mechanism based on a comparison between the first length and a set length. This allows for adjustment of the length of the insulating paper exposed outside the motor stator. For example, during continuous paper insertion by the paper insertion assembly 20, the paper feeding length of the paper insertion assembly 20 can be adjusted based on the comparison between the determined first length and the set length. If the first length is less than the set length, the paper insertion assembly 20 continues to feed paper into the motor stator until the first length equals the set length.

[0027] It should be understood that the above-mentioned first length equals the set length means that within the range that meets the tolerance requirements, the first length can be considered equal to the set length. For example, if the exposed length of the insulating paper is set to 3cm and the tolerance is ±2mm, then within the range of 2.8cm to 3.2cm, the first length is considered equal to the set length.

[0028] As can be seen from the above description, in the technical solution disclosed in this application, the length of the insulating paper exposed on the motor stator is determined by the first signal and the second signal detected by the paper insertion detection mechanism 100, and the insertion depth of the paper insertion mechanism is adjusted by the data processing module according to the comparison result between the determined length of the insulating paper exposed on the motor stator and the set length, thereby improving the paper insertion accuracy.

[0029] Continue to refer to Figure 3 , Figure 4 and Figure 5 As shown, the paper insertion detection mechanism 100 provided in this embodiment further includes a base 140 and a main detection shaft 150. The main detection shaft 150 is slidably mounted within the base 140 and can slide vertically. The probe 120 is provided at the end of the main detection shaft 150 exposed outside the base 140. The driving member 190 is an elastic member disposed within the base 140, with its two ends pressing against the base 140 and the main detection shaft 150, respectively. For example, the elastic member can be a compression spring, such as a metal spring or a rubber spring, or other different types of elastic members. When the probe 120 presses against the end of the motor stator or the end of the insulating paper, the elastic member provides a pressure to ensure the accuracy of the sensor 130's position during detection.

[0030] It should be understood that the probe 120 and the main detection shaft 150 can be separate or integrated. When they are separate, the probe 120 and the main detection shaft 150 can be fixedly connected by different methods such as bonding, snap-fitting, or threaded connection.

[0031] Continue to refer to Figure 3 , Figure 4 and Figure 5As shown, in a specific configuration, the base 140 is fixed to the bracket 110, such as by means of connectors (bolts, screws, rivets), or by different methods such as bonding, welding, or snap-fitting. The base 140 has a cavity with one open end, in which the main detection shaft 150 is slidably fitted and can slide back and forth vertically. In an optional configuration, the base 140 has two opposing first sliding grooves 141, which are formed on the side wall of the base 140. Correspondingly, a sliding shaft is detachably fixedly connected to the main detection shaft 150, and this sliding shaft is slidably fitted into the first sliding grooves 141. For example, the sliding shaft passes through the end of the main detection shaft 150 located within the cavity and is inserted into the two first sliding grooves 141, allowing it to slide within them. The first slide groove 141 is an elongated slot. The cooperation between the sliding shaft and the first slide groove 141 ensures that the main detection shaft 150 can only slide in the vertical direction and will not rotate during sliding. On the other hand, the cooperation between the sliding shaft and the first slide groove 141 limits the sliding stroke of the main detection shaft 150, avoiding the risk of the main detection shaft 150 sliding out of the base 140, and ensuring the stability of the entire mechanism.

[0032] During assembly, the main detection shaft 150 is inserted into the base 140 and the elastic element is compressed. Then, the sliding shaft is inserted through the first groove and fixedly connected to the main detection shaft 150, thereby confining the main detection shaft 150 within the base 140.

[0033] In one alternative, the end of the main detection shaft 150 located within the base 140 is provided with a through hole, and the sliding shaft passes through the through hole and is fixed by interference fit or by adhesive bonding.

[0034] The sensor 130 provided in this embodiment is a displacement sensor 130, which can be a non-contact displacement sensor 130 or a contact displacement sensor 130. In an optional embodiment, the sensor 130 is a contact displacement sensor 130, thereby making the measured data more accurate.

[0035] When the contact displacement sensor 130 is installed, it is fixedly connected to the main detection shaft 150 so that the position of the probe 120 is determined by the position of the main detection shaft 150. For example, a second sliding groove 142 is provided on the base 140, and a first connecting plate 180 is provided on the portion of the main detection shaft 150 located within the base 140. The first connecting plate 180 is fixedly connected to the main detection shaft 150, and passes through the second sliding groove 142 and protrudes outside the base 140. The measuring end of the contact displacement sensor 130 is fixedly connected to the first connecting plate 180. Specifically, the contact displacement sensor 130 is installed on the bracket 110, and the measuring end of the contact displacement sensor 130 is fixedly connected to the portion of the first connecting plate 180 exposed in the base 140.

[0036] It should be understood that the first connecting plate 180 can slide within the second slide groove 142 to ensure that the first connecting plate 180 can slide synchronously with the main detection shaft 150.

[0037] When this arrangement is adopted, the contact displacement sensor 130 and the base 140 can be arranged side by side, making the whole device compact and occupying less space.

[0038] Continue to refer to Figure 3 , Figure 4 and Figure 5 As shown, in one optional embodiment, the first connecting plate 180 is an inverted L-shaped connecting plate. The vertical portion of the first connecting plate 180 is fixedly connected to the main detection shaft 150, and the horizontal portion of the first connecting plate 180 is fixedly connected to the measuring end of the contact displacement sensor 130. Specifically, the vertical portion of the first connecting plate 180 can be fixedly connected to the main detection shaft 150 by bolts or screws, or by different methods such as bonding or welding. The horizontal portion of the first connecting plate 180 can be fixedly connected to the measuring end of the contact displacement sensor 130 by bolts or screws.

[0039] Continue to refer to Figure 3 , Figure 4 and Figure 5As shown in the embodiment of this application, the paper insertion depth compensation mechanism may further include a clearance mechanism 160. This clearance mechanism 160 is used to lower the probe 120 to avoid paper insertion when the motor stator rotates, thus preventing damage to the insulating paper due to the pressure of the probe 120 during motor stator rotation. For example, after one paper insertion is completed, the lifting and rotating mechanism 10 drives the motor stator to rotate a set distance so that the next insulating paper slot aligns with the paper insertion assembly 20 for the next paper insertion. Before the motor stator rotates, the clearance mechanism 160 lowers the probe 120, and then the lifting and rotating mechanism 10 drives the motor stator to rotate. When the motor stator rotates to the desired position, the clearance mechanism 160 exits its working state. At this time, the probe 120, under the action of the driving member 190, can press against the end of the motor stator to detect the paper insertion depth during the paper insertion process.

[0040] In the embodiments of this application, the avoidance mechanism 160 can be implemented with different structures. Two specific avoidance mechanisms 160 are exemplified below.

[0041] In one feasible embodiment, the avoidance mechanism 160 can be a linear drive mechanism. The moving end of this linear drive mechanism can slide relative to the probe 120, and after sliding to a set distance, it can drive the probe 120 to descend. For example, when the linear drive mechanism is not in operation, the probe 120 can rise and fall under the action of the drive member 190 to press against the end of the motor stator or the end of the insulating paper. When the linear drive mechanism is in operation, it can drive the probe 120 to descend to avoid the insulating paper.

[0042] For example, the avoidance mechanism 160 can be connected to the main detection shaft 150. A second connecting plate 170 is provided on the main detection shaft 150, passing through and exposed above the base 140, and is slidable relative to the base 140. If a third sliding groove is provided on the base 140, the second connecting plate 170 can pass through and slide within the third sliding groove. The linear drive mechanism is located outside the base 140, and its moving end slides in cooperation with the second connecting plate 170. If the second connecting plate 170 has a channel, which can be a through hole or a U-shaped groove, the moving end of the linear drive mechanism passes through this through hole or U-shaped groove. Furthermore, a limiting member is provided at the end of the moving end, which can press against the second connecting plate 170. This limiting member can be a shoulder, nut, or other structure.

[0043] In actual operation, when the moving end is in the first state, the limiting member is away from the second connecting plate 170, and the probe 120 can abut against the end of the motor stator or the insulating paper; that is, when the linear drive mechanism is in the non-working state, the probe 120 can press against the end of the motor stator or the insulating paper within its stroke. When the moving end is in the second state, the limiting member abuts against the second connecting plate 170, and the probe 120 avoids the end of the insulating paper. That is, when the linear drive mechanism is in the working state, the linear drive mechanism can drive the probe 120 down to avoid the end of the insulating paper.

[0044] It should be understood that the linear drive mechanism can be a common linear drive mechanism such as a cylinder, hydraulic cylinder or linear motor, which will not be described in detail here.

[0045] The second connecting plate 170 mentioned above can be an inverted L-shaped connecting plate, and its arrangement is the same as that of the first connecting plate 180, which will not be described in detail here.

[0046] In another embodiment, the moving part of the avoidance mechanism 160 can be relatively fixed to the probe 120, and the relative movement of the probe 120 during operation is achieved through the structure of the avoidance mechanism 160 itself. For example, the avoidance mechanism 160 is fixedly connected to the main detection shaft 150. The avoidance mechanism 160 is a cylinder, and the piston rod (moving part) of the cylinder is fixedly connected to the main detection shaft 150. The rod chamber of the cylinder is connected to an air supply pipe, and an exhaust valve is installed on this air supply pipe. The exhaust valve closes when the piston rod retracts and opens when the piston rod extends. Specifically, during operation, the rodless chamber of the cylinder is not connected to a pipe, while the rod chamber is connected to the air supply pipe. When the cylinder is not in operation, the exhaust valve is open, and the probe 120 can extend and retract under the action of the elastic element, simultaneously driving the piston rod to extend and retract synchronously. When the cylinder is in operation, the exhaust valve is closed, the air supply pipe supplies air to the rod chamber, causing the piston rod to descend, thereby causing the piston rod to retract, allowing the probe 120 to avoid the insulating paper.

[0047] The cylinder can also be connected to the main detection shaft 150 via a connecting plate, which is a third connecting plate, and its arrangement is similar to that of the first connecting plate 180. Specifically, a third sliding groove is formed on the base 140; the third connecting plate is located on the portion of the main detection shaft 150 within the base 140. Furthermore, the third connecting plate passes through the third sliding groove and protrudes outside the base 140, and can slide within the third sliding groove. The piston rod is fixedly connected to the third connecting plate.

[0048] In an alternative arrangement, when arranging the sensor 130 and the avoidance mechanism 160, the sensor 130 and the avoidance mechanism 160 can be positioned on opposite sides of the probe 120, thus forming a similar symmetrical arrangement. This reduces the space occupied by the entire mechanism. Furthermore, when arranged in the above manner, the second slide 142 and the third slide 142 can be arranged opposite each other, improving the structural strength of the base 140.

[0049] In one alternative scheme, when there are two or more paper insertion components 20, there are also two or more corresponding paper insertion detection mechanisms 100, with a one-to-one correspondence between the two.

[0050] like Figure 1 and Figure 2 As shown, this application embodiment also provides a paper insertion mechanism, which includes a lifting and rotating mechanism 10, a paper insertion assembly 20, and a paper insertion depth compensation mechanism as described above; wherein, A space for accommodating the motor stator is formed between the lifting and rotating mechanism 10 and the paper insertion assembly 20; the paper insertion depth compensation mechanism is located on the same side of the motor stator as the lifting and rotating mechanism 10.

[0051] In the above technical solution, the length of the insulating paper exposed on the motor stator is determined by the first signal and the second signal detected by the paper insertion detection mechanism 100, and the insertion depth of the paper insertion mechanism is adjusted by the data processing module according to the comparison result between the determined length of the insulating paper exposed on the motor stator and the set length, thereby improving the paper insertion accuracy.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
