Description

Technical Field

[0001] This application relates to the field of automated processing equipment technology, and in particular to an automatic wire winding and tinning device. Background Technology

[0002] Automatic winding and tinning equipment is used to automatically wind and tin the stator assembly in the cooling fan in sequence: through automatic feeding, automatic transfer and automatic unloading, the winding process and tinning process of the stator are connected online, replacing manual labor to complete high-precision winding and tinning operations, thereby reducing intermediate transfer links and improving the consistency of stator processing and overall production efficiency.

[0003] Existing automated winding and tinning equipment sequentially winds and tins the stator in a cooling fan, requiring no manual intervention throughout the process. The winding mechanism typically comprises multiple winding assemblies. A transport mechanism sequentially places the stators to be wound and tinned onto each winding assembly. Once all winding assemblies on the winding mechanism are filled with stators, the entire winding mechanism begins operation, winding the stators on each assembly. After winding is complete, the process proceeds to the subsequent tinning step, ultimately collecting the finished stators.

[0004] However, existing automatic wire winding and tinning equipment has the following drawbacks: multiple winding components operate synchronously, and the winding mechanism needs to wait for the transmission component to fill all the winding components one by one before starting winding. The winding mechanism only starts after all winding components are loaded. The winding components that are filled first are idle while waiting for subsequent winding components to be filled, resulting in long idle time for the winding components and low equipment utilization. How to solve the above technical problems is a question that those skilled in the art need to consider. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides an automatic wire winding and tinning device.

[0006] The automatic winding and tinning equipment provided in this application includes a conveying mechanism, a winding mechanism, and a tinning mechanism. The conveying mechanism is located on one side of the stator conveying direction and is used to convey the stator. The winding mechanism includes multiple independently operating winding assemblies, each including a pressing member, a winding member, and two support members. The two support members are connected and configured to rotate about their geometric centers. The support members support the stator, and the two support members alternately correspond to the winding members. When one support member rotates to a position corresponding to the winding member, the pressing member moves towards the support member to clamp the stator. After the stator winding is completed, the pressing member separates from the corresponding support member, and the support member supporting the wound stator rotates away from the winding member. The tinning mechanism is located downstream of the winding mechanism along the stator conveying direction and is used to perform tinning on the wound stator.

[0007] Understandably, each winding assembly operates independently. A single winding assembly can start immediately after loading, without waiting for other winding assemblies to fill, thus shortening the idle waiting time of the first-filled winding assemblies. When one support rotates to correspond with the winding assembly and begins winding, another support can simultaneously support the stator to be processed, allowing loading / unloading and winding actions to be performed in parallel within the same assembly. With the support and winding assembly aligned, the crimping member moves towards the support to clamp the stator, ensuring its stability during winding. After the stator winding is complete, the crimping member separates from the support, and the support supporting the wound stator moves away from the winding assembly, allowing the wound stator to leave the winding station and facilitating its transfer downstream. The tinning mechanism tins the wound stator, connecting the winding and tinning processes online, reducing intermediate transfer steps. This application reduces the waiting time of the winding assembly and improves the utilization rate of the automatic winding and tinning equipment by combining the independent operation of the winding assembly with the alternating operation of the support component.

[0008] In one embodiment, when a support member corresponds to a winding member, the straight line direction of the two support members is perpendicular to the conveying direction of the stator; the support member rotates along the conveying direction of the stator, and the single rotation angle of the support member is 180°.

[0009] Understandably, the two support components are located on the feed and discharge sides along the stator conveying direction, respectively. When the two support components alternately correspond to the winding component, their positional relationship is coordinated with the stator's conveying path, which helps reduce interference between the rotation of the support components and the stator conveying process. The support components rotate along the stator conveying direction with a single rotation angle of 180°, allowing the support component in the winding position and the support component in the loading / unloading position to exchange positions after one rotation, thus achieving a regular switching between the two support components in the winding position and the loading / unloading position. This facilitates a smooth and orderly alternation between the two support components, shortening the switching time between loading / unloading and winding within a single winding assembly.

[0010] In one embodiment, the support includes a support structure and two support structures disposed on top of the support structure, each support structure being configured to be rotatable and connected to the support structure.

[0011] Understandably, the support structure provides basic support for the stator, and two support structures are positioned on top of the support structure, allowing the support structures to rotate together with it. Each support structure is constructed to be driven to rotate and connected to the support structure, enabling it to support the stator while also being driven to rotate independently. This allows the support structure to adjust the stator's attitude during winding to match the routing direction of the winding components. This enhances the ability to adjust the stator's attitude beyond simply providing support, thus meeting the stator's requirements for winding angles.

[0012] In one embodiment, the support structure includes a first support rod, a second support rod, and a connecting structure. The first support rod is arranged in a vertical direction, the second support rod is arranged in a vertical direction and slidably connected to the top of the first support rod, and the connecting structure is connected to the top of the second support rod.

[0013] Understandably, the first support rod provides a vertical support foundation for the support structure, while the second support rod can slide vertically relative to the first. By adjusting the support height of the second support rod in the vertical direction, it can accommodate stators of different heights. The connecting structure is connected to the top of the second support rod, rises and falls with it, and connects to the stator, allowing the stator's contact position to change with height adjustment. The first support rod, the second support rod, and the connecting structure work together to provide the support structure with vertical height adjustment capability, which is beneficial for automatic winding and tinning equipment to adapt to stators of different specifications.

[0014] In one embodiment, the crimping member is disposed above two support structures; the two support structures are spaced apart in the horizontal direction and are located at the same horizontal height; the winding member is configured to be close to or away from the connecting structure.

[0015] Understandably, the crimping component presses down on the stator from above, cooperating with the support component to press the stator against it. The two support structures, positioned separately at the same horizontal level, provide symmetrical and consistent support to the stator, reducing uneven stress on the stator during crimping. The winding component moves closer to the stator near the connecting structure during winding and further away during loading / unloading or after winding is complete, allowing space for stator placement and rotation of the support component. The top-mounted crimping component, the horizontally spaced arrangement of the two support structures, and the retractable design of the winding component all contribute to uniform stress on the stator during crimping and reduce movement interference between the crimping component, support structures, and winding component.

[0016] In one embodiment, the winding mechanism further includes a sensing component, which includes a first sensor and a second sensor. The first sensor is connected to the top of the support structure and is disposed corresponding to the connecting structure; the second sensor is connected to the winding member at the position corresponding to the connecting structure.

[0017] Understandably, the first sensor can sense the stator's positioning at the connection structure to determine whether the stator is properly supported; the second sensor is connected to the position corresponding to the winding component and the connection structure to sense the relative position between the winding component and the stator at the connection structure. By using the first and second sensors to sense the stator's positioning and winding alignment respectively, it is beneficial to reduce winding abnormalities caused by the stator not being in place or misalignment, and improve the reliability of the winding operation.

[0018] In one embodiment, the soldering mechanism includes a receiving box and a collecting box. The receiving box is used to receive molten solder, and the collecting box is used to collect solder dross. The opening of the receiving box is vertically upward, and the opening of the collecting box is vertically upward. The openings of the receiving box and the collecting box are connected. The conveying mechanism includes a conveying component and a cleaning component. The cleaning component is used to transfer the solder dross in the receiving box to the collecting box.

[0019] Understandably, the receiving box holds the molten solder for stator soldering, while the collecting box collects solder dross for separate processing. Solder dross floating on the surface of the molten solder can be transferred to the collecting box at the same level through a connecting opening, facilitating dross removal. A cleaning component automatically removes the solder dross from the receiving box to the collecting box. This interconnected arrangement of the receiving and collecting boxes, along with the automatic dross removal by the cleaning component, helps reduce the impact of solder dross on the molten solder and soldering quality, minimizes downtime for manual dross removal, and allows the soldering process to continue continuously.

[0020] In one embodiment, the receiving box is configured to be vertically movable, and the collection box is detachably connected to the receiving box.

[0021] Understandably, the receiving box can be adjusted in height relative to the stator according to the stator's soldering requirements, facilitating control of the stator's immersion depth in molten solder and enabling maintenance of the receiving box. The collecting box is detachably connected to the receiving box, allowing it to be separated for cleaning or replacement after solder dross accumulates. The adjustable height of the receiving box and the detachable connection of the collecting box facilitate adjustment of the soldering depth and periodic cleaning of solder dross, simplifying the use and maintenance of automatic wire winding soldering equipment.

[0022] In one embodiment, the soldering mechanism further includes a storage box disposed downstream of the receiving box along the stator conveying direction and spaced apart from the receiving box, the storage box being used to store flux.

[0023] Understandably, the storage box is located downstream of the receiving box along the stator conveying direction and spaced apart from the receiving box, so that the flux storage position is arranged separately from the receiving box containing the solder liquid along the conveying direction, in order to reduce the mixing between the flux and the solder liquid, and to allow the stator to undergo two steps of flux application and solder application during the conveying process.

[0024] In one embodiment, the automatic wire winding and tinning equipment further includes a control mechanism, which is electrically connected to the conveying mechanism, the winding mechanism, and the tinning mechanism.

[0025] Understandably, the control mechanism can send control signals to the conveying mechanism, winding mechanism, and tinning mechanism respectively, and uniformly schedule the three stages of conveying, winding, and tinning. Through the electrical connection control of each mechanism, it is beneficial to coordinate the connection between the conveying, winding, and tinning processes, reduce manual intervention, and enable the automatic winding and tinning equipment to automatically carry out the processing according to the predetermined flow.

[0031] The following combination Figures 1 to 4 This application will be described in further detail below.

[0032] In one embodiment, the automatic winding and tinning equipment includes a conveying mechanism 1, a winding mechanism 2, and a tinning mechanism 3. The conveying mechanism 1 is disposed on one side of the stator conveying direction and is used to convey the stator. The winding mechanism 2 includes multiple independently operating winding assemblies 21. Each winding assembly 21 includes a crimping member 212, a winding member 213, and two support members 211. The two support members 211 are connected and configured to be rotatable about the geometric center of the two support members 211. The support members 211 are used to support the stator, and the two support members 211 alternately correspond to the winding member 213. When one support member 211 rotates to a state corresponding to the winding member 213, the crimping member 212 moves toward the support member 211 to clamp the stator. After the stator winding is completed, the crimping member 212 separates from the corresponding support member 211, and the support member 211 supporting the wound stator rotates away from the winding member 213. The tinning mechanism 3 is located downstream of the winding mechanism 2 along the stator conveying direction and is used to perform tinning on the wound stator.

[0033] In this embodiment, refer to Figures 2 to 4 The conveying mechanism 1 is arranged on one side of the stator conveying path. The conveying mechanism 1 moves along three axes to handle the feeding and discharging of the stator. The winding mechanism 2 includes three independently operating winding assemblies 21. Two support members 211 are horizontally arranged and interconnected. The two support members 211 rotate around the geometric center of their connected structure, driven by a motor. The stator is placed on the support member 211 and rotates with it. The two support members 211 move sequentially to a position facing the winding member 213. After the winding operation is completed, the pressing member 212 rises and disengages from the support member 211. Subsequently, the support member 211 drives the wound stator to rotate and leave the winding area.

[0034] Each winding assembly 21 operates independently. A single winding assembly 21 can start immediately after loading, without waiting for the other winding assemblies 21 to fill, thus shortening the idle waiting time of the first-filled winding assemblies 21. When one support 211 rotates to correspond with the winding assembly 213 and begins winding, another support 211 can simultaneously support the stator to be processed, allowing loading / unloading and winding actions to be performed in parallel within the same assembly. When the support 211 corresponds with the winding assembly 213, the crimping member 212 moves toward the support 211 to clamp the stator, keeping it stable during winding. After the stator winding is complete, the crimping member 212 separates from the support 211, and the support 211 supporting the wound stator rotates away from the winding assembly 213, allowing the wound stator to leave the winding station and facilitating its transfer downstream. The tinning mechanism 3 performs tinning on the stator after winding, connecting the winding and tinning processes online and reducing intermediate transfer links. This application reduces the waiting time of the winding assembly 21 by both allowing the winding assembly 21 to operate independently and allowing the support component 211 to work alternately, thereby improving the utilization rate of the automatic winding and tinning equipment.

[0035] In one embodiment, the automatic winding and tinning equipment further includes a control mechanism 4, which is electrically connected to the conveying mechanism 1, the winding mechanism 2, and the tinning mechanism 3.

[0036] In this embodiment, refer to Figures 1 to 3 The control mechanism 4 can be an industrial computer, and it is located upstream of the winding mechanism 2 in the stator conveying direction. The control mechanism 4 is electrically connected to the conveying mechanism 1, the winding mechanism 2, and the tinning mechanism 3 via cables.

[0037] The control mechanism 4 can send control signals to the conveying mechanism 1, the winding mechanism 2, and the tinning mechanism 3 respectively, and uniformly schedule the three stages of conveying, winding, and tinning. By controlling the electrical connection of each mechanism through the control mechanism 4, it is beneficial to coordinate the connection between the conveying, winding, and tinning processes, reduce manual intervention, and enable the automatic winding and tinning equipment to automatically carry out the processing according to the predetermined process.

[0038] In one embodiment, when a support member 211 corresponds to a winding member 213, the straight line direction of the two support members 211 is perpendicular to the conveying direction of the stator; the support member 211 rotates along the conveying direction of the stator, and the single rotation angle of the support member 211 is 180°.

[0039] In this embodiment, refer to Figure 2 and Figure 4Both support members 211 are arranged horizontally, and the line connecting the two support members 211 is perpendicular to the conveying direction of the stator. The rotation direction of the support member 211 is the same as the conveying direction of the stator, and the angle of a single rotation of the support member 211 is 180°.

[0040] Two support members 211 are located on the feed side and discharge side along the stator conveying direction, respectively. When the two support members 211 alternately correspond to the winding member 213, the positional relationship of the support members 211 is coordinated with the stator conveying path, which helps to reduce the mutual interference between the rotation of the support members 211 and the stator conveying process. The support members 211 rotate along the stator conveying direction with a single rotation angle of 180°, so that the support member 211 in the winding position and the support member 211 in the loading / unloading position complete the position exchange after one rotation, thereby realizing the regular switching of the two support members 211 between the winding position and the loading / unloading position. This facilitates the smooth and orderly alternation between the two support members 211, shortening the switching time between loading / unloading and winding within a single winding assembly 21.

[0041] In one embodiment, the support member 211 includes a support structure 2111 and two support structures 2112, the two support structures 2112 being disposed on top of the support structure 2111, each support structure 2112 being configured to be rotatable and connected to the support structure 2111.

[0042] In this embodiment, refer to Figure 2 and Figure 4 The supporting structure 2111 is plate-shaped and arranged horizontally. Two support structures 2112 are spaced apart and connected to the top of the supporting structure 2111. Each support structure 2112 is connected to an independent drive module at its bottom, so that each support structure 2112 can rotate independently on the supporting structure 2111.

[0043] The support structure 2111 provides basic support for the stator, and two support structures 2112 are disposed on top of the support structure 2111, allowing the support structures 2112 to rotate together with the support structure 2111. Each support structure 2112 is constructed to be driven to rotate and connected to the support structure 2111, enabling the support structure 2112 to be driven to rotate independently while supporting the stator. This allows the support structure 2112 to adjust the stator's attitude during winding to match the routing direction of the winding member 213. This facilitates increased stator attitude adjustment capability based on the stator's support, thus meeting the stator's requirements for winding angles.

[0044] In one embodiment, the support structure 2112 includes a first support rod 21121, a second support rod 21122, and a connecting structure 21123. The first support rod 21121 is arranged in a vertical direction, the second support rod 21122 is arranged in a vertical direction and slidably connected to the top of the first support rod 21121, and the connecting structure 21123 is connected to the top of the second support rod 21122.

[0045] In this embodiment, refer to Figure 4 The diameter of the first support rod 21121 is larger than the diameter of the second support rod 21122, and the length of the second support rod 21122 is greater than the length of the first support rod 21121. The second support rod 21122 is slidably connected to the first support rod 21121 via an electric telescopic rod. The connecting structure 21123 is movably connected to the top end of the second support rod 21122, and the connecting structure 21123 has a connecting groove for engaging with the stator.

[0046] The first support rod 21121 provides a vertical support foundation for the support structure 2112. The second support rod 21122 can slide vertically relative to the first support rod 21121. By adjusting the support height of the second support rod 21122 in the vertical direction, it can accommodate stators of different heights. The connecting structure 21123 is connected to the top of the second support rod 21122, and rises and falls together with the second support rod 21122 and connects to the stator, so that the receiving position of the stator changes with the height adjustment. The first support rod 21121, the second support rod 21122, and the connecting structure 21123 work together to provide the support structure 2112 with vertical height adjustment capability, which is beneficial for the automatic winding and tinning equipment to adapt to stators of different specifications.

[0047] In one embodiment, the crimping member 212 is disposed above the two support structures 2112; the two support structures 2112 are spaced apart in the horizontal direction and are located at the same horizontal height; the winding member 213 is configured to be close to or away from the connecting structure 21123.

[0048] In this embodiment, refer to Figure 2 and Figure 4 A crimping member 212 is positioned vertically above the support member 211, moving closer to or further away from the support member 211. When one of the support members 211 rotates to align with the winding member 213, the crimping member 212 descends and presses against the stator on the support member 211. The winding member 213 can move closer to or further away from the support member 211.

[0049] The crimping member 212 presses down on the stator from above, cooperating with the support member 211 to press the stator. The two support structures 2112 support the stator separately at the same horizontal height, so that the stator receives symmetrical support at the same position and height, reducing uneven force on the stator during crimping. The winding member 213 is close to the stator at the connecting structure 21123 during winding, and moves away when loading / unloading or after winding is completed, making room for the placement and removal of the stator and the rotation of the support member 211. The top placement of the crimping member 212, the horizontal spacing of the two support structures 2112, and the retractable design of the winding member 213 help to ensure uniform force on the stator during crimping and reduce movement interference between the crimping member 212, the support structure 2112, and the winding member 213.

[0050] In one embodiment, the winding mechanism 2 further includes a sensing component 22, which includes a first sensor 221 and a second sensor 222. The first sensor 221 is connected to the top of the support structure 2111 and is correspondingly disposed with respect to the connecting structure 21123; the second sensor 222 is connected to the winding member 213 at the position corresponding to the connecting structure 21123.

[0051] In this embodiment, refer to Figure 1 , Figure 2 and Figure 4 The first sensor 221 can be a position sensor, and the second sensor 222 can be a distance sensor. The first sensor 221 and the second sensor 222 are electrically connected to the control mechanism 4 respectively.

[0052] The first sensor 221 senses the stator's positioning at the connecting structure 21123 to determine whether the stator is properly supported. The second sensor 222 is connected to the position corresponding to the winding member 213 and the connecting structure 21123 to sense the relative position between the winding member 213 and the stator at the connecting structure 21123. By using the first sensor 221 and the second sensor 222 to sense the stator's positioning and winding alignment respectively, it is beneficial to reduce winding abnormalities caused by the stator not being in place or misalignment, thereby improving the reliability of the winding operation.

[0053] In one embodiment, the soldering mechanism 3 includes a receiving box 31 and a collecting box 32. The receiving box 31 is used to receive molten solder, and the collecting box 32 is used to collect solder dross. The opening direction of the receiving box 31 is vertically upward, and the opening direction of the collecting box 32 is vertically upward. The openings of the receiving box 31 and the collecting box 32 are connected. The conveying mechanism 1 includes a conveying component 11 and a cleaning component 12. The cleaning component 12 is used to transfer the solder dross in the receiving box 31 to the collecting box 32.

[0054] In this embodiment, refer to Figure 3 and Figure 4The size of the receiving box 31 is larger than that of the collecting box 32, and the top edge of the opening of the receiving box 31 and the top edge of the opening of the collecting box 32 are connected at the opening position. The conveying assembly 11 can be a robotic arm, and the cleaning assembly 12 can be a scraper. The cleaning assembly 12 is connected upstream of the conveying assembly 11 along the stator conveying direction. The cleaning assembly 12 can transfer the solder dross in the receiving box 31 to the collecting box 32 through the channel connecting the top of the receiving box 31 and the collecting box 32. The receiving box 31 is used to hold molten solder for stator soldering, and the collecting box 32 is used to collect solder dross for separate treatment from the molten solder. Solder dross floating on the surface of the molten solder can be transferred to the collecting box 32 at the same horizontal level through a connecting opening, facilitating dross cleaning. The cleaning component 12 is used to transfer the solder dross in the receiving box 31 to the collecting box 32 for automatic removal of solder dross. The connected arrangement of the receiving box 31 and the collecting box 32, along with the automatic dross removal by the cleaning component 12, helps to reduce the impact of solder dross on the molten solder and the soldering quality, and reduces the need for manual dross removal during downtime, allowing the soldering process to be carried out continuously.

[0055] In one embodiment, the receiving box 31 is configured to be vertically movable, and the collection box 32 is detachably connected to the receiving box 31.

[0056] In this embodiment, refer to Figure 3 The bottom of the receiving box 31 is connected to a lifting module, which allows the receiving box 31 to rise or fall vertically. The collection box 32 is detachably connected to the upstream of the receiving box 31 along the stator conveying direction.

[0057] The receiving box 31 can be adjusted in height relative to the stator according to the stator's soldering requirements, facilitating control of the stator's immersion depth in molten solder and enabling maintenance of the receiving box 31. The collecting box 32 is detachably connected to the receiving box 31, allowing it to be separated. After solder dross accumulates in the collecting box 32, it can be removed for cleaning or replacement. The adjustable height of the receiving box 31 and the detachable connection of the collecting box 32 facilitate adjustment of the soldering depth and periodic cleaning of solder dross, simplifying the use and maintenance of the automatic winding soldering equipment.

[0058] In one embodiment, the soldering mechanism 3 further includes a storage box 33, which is disposed downstream of the receiving box 31 along the stator conveying direction and spaced apart from the receiving box 31. The storage box 33 is used to store flux.

[0059] In this embodiment, refer to Figure 3The size of the storage box 33 is smaller than that of the receiving box 31. The storage box 33 is located downstream of the receiving box 31 along the stator conveying direction and is spaced apart from the receiving box 31. This makes the flux storage position separate from the receiving box 31 which contains the molten solder along the conveying direction, so as to reduce the mixing between the flux and the molten solder. This allows the stator to go through the two steps of flux application and solder application in sequence during the conveying process.

[0060] In this embodiment, refer to Figures 1 to 3 The automatic winding and tinning equipment also includes a collecting mechanism 5, which is located downstream of the storage box 33 along the stator conveying direction. The collecting mechanism 5 is used to support and transfer the tray. The conveying mechanism 1 also includes a transfer assembly 13, which can be a three-axis robot. The transfer assembly 13 is located downstream of the storage box 33 along the stator conveying direction. The transfer assembly 13 is located above the collecting component in the vertical direction and is used to transfer the tinned stator onto the tray.

[0061] The implementation principle of this application embodiment is as follows: The robotic arm places the stator to be wound and tinned on the support member 211 at the loading position. The support member 211 rotates 180°, flipping the stator to the position corresponding to the winding member 213. The pressing member 212 presses down to fix the stator, and the winding member 213 moves towards the connecting structure 21123 and performs the winding operation. After the winding is completed, the pressing member 212 lifts up to release the stator, and the support member 211 rotates 180° in the same direction to turn out. The robotic arm picks up the wound stator and moves it to the storage box 33 to dip it in flux. Then, the stator is moved to the receiving box 31 to be immersed in molten solder to complete the tinning process. The transfer component 13 transfers the wound and tinned stator to the collection mechanism 5. The entire process is seamlessly connected, completing the automated assembly line operation. Compared with the prior art, this automatic winding and tinning equipment has the advantages of short idle time and high working efficiency.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
