Abstract
Description
Technical Field
[0001] This invention relates to the field of winding machine chuck technology, and particularly to an automated winding chuck. Background Technology
[0002] In electronic transformer manufacturing technology, winding machines and winding chucks are required. The winding chucks hold the coil bobbin, and the rotation of the coil bobbin is caused by driving the winding chucks. Generally, the coil bobbin is directly fitted onto the clamping part of the winding chuck, and then the mounting part of the winding chuck is fixed to the winding machine. The winding machine drives the winding chuck to rotate along its axis, thereby causing the coil bobbin on the clamping part to rotate and wind.
[0003] Regarding the technical means of mounting the coil bobbin on the winding clamp, the existing technology directly sleeves and mounts the coil bobbin on the outside of the winding clamp, such as the transformer winding starting and fixing device disclosed in Chinese Patent No. CN212750611U. However, there may be a gap between the winding clamp and the coil bobbin, making it difficult to ensure a stable connection between the winding clamp and the coil bobbin. During the rotation winding process, the coil bobbin may loosen and the winding technology cannot be implemented.
[0004] To address the aforementioned issues, existing methods employ a clamp body with multiple clamping plates. The coil bobbin is fitted inside these clamping plates, and the clamp body is housed within a sleeve. A drive assembly, in conjunction with the sleeve, synchronously opens the clamping plates to place or remove the coil bobbin. An elastic element then retracts the clamping plates to hold the coil bobbin. This technique is employed in Chinese patents CN214043403U (disclosed as a T-button inductor winding clamp) and CN203983031U (disclosed as a winding clamp). However, this approach results in a complex winding clamp structure, high design and manufacturing costs, and the clamp is held solely by multiple clamping plates without any limiting components to restrict the rotation and axial movement of the coil bobbin. Summary of the Invention
[0005] The main objective of this invention is to provide an automated winding clamp to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention proposes an automated winding clamp, comprising: A sleeve, wherein the sleeve has a receiving cavity inside; A central column is disposed within the receiving cavity and rotates with the sleeve, and has a gap. The gap passes through both sides of the central column in the radial direction and passes through the end of the central column away from the sleeve in the axial direction. The coil frame is sleeved on the outside of the central column. A pressure cap, which abuts against the end of the central column away from the sleeve and rotates with the central column, and is mounted on the movable tailstock of the winding machine; Insertion block, which is mounted on the pressure cap and housed within the gap, for the purpose of opening up the central column on both sides of the gap; The two ends of the coil frame abut against the sleeve and the pressure cap, respectively.
[0007] In an optional embodiment, a first slot is further provided on the outer side of the central column, the first slot extending along the axial direction of the central column, and the first slot is used to hold the coil frame.
[0008] In an optional embodiment, the central post is transitionally fitted with the receiving cavity, and the automated winding clamp further includes a fixing member mounted on the sleeve and used to fix the central post on the sleeve.
[0009] In an optional embodiment, the end of the gap near the pressure cap is provided with a chamfer to facilitate the insertion of the insert into the gap; The end of the insert block away from the pressure cap is also provided with a chamfer to facilitate the insertion of the insert block into the gap.
[0010] In an alternative embodiment, the fastener includes a screw that is threadedly connected to the sleeve and abuts against the central post to secure the central post to the sleeve.
[0011] In an optional embodiment, the central column is further provided with a through hole that extends through both sides of the central column in the radial direction and connects to the end of the gap away from the pressure cap.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. The automated winding clamp of the present invention comprises a sleeve, a central column, a pressure cap, and an insert block. The central column has a gap, and the insert block can be inserted into or disengaged from this gap as the pressure cap moves. During the insertion of the insert block into the gap, the central column deforms and expands on both sides of the gap under the squeezing action of the insert block. The coil frame, which is sleeved on the outside of the central column, is held in place by the central column, and the central column provides continuous radial tension, thereby ensuring that the coil frame is securely mounted on the central column and preventing the coil frame from loosening during the winding process, which would prevent the winding technology from being implemented.
[0013] The pressure cap abuts against the end of the central column away from the sleeve and rotates with the central column. The two ends of the coil frame abut against the sleeve and the pressure cap respectively. The pressure cap, together with the sleeve, clamps the coil frame in the axial direction of the central column, further stabilizing the coil frame on the central column, and at the same time effectively suppressing the jumping of the end of the coil frame.
[0014] The automated winding clamp of the present invention has a simple structure, is easy to install, does not require too many parts, reduces the risk of failure, and has low design and manufacturing costs.
[0015] 2. A first retaining groove is also provided on the outer side of the central column, extending along the axis of the central column to the end opposite to the pressure cap. The first retaining groove is used to hold the coil frame in place. When installing the coil frame, the first retaining block of the coil frame is engaged in the first retaining groove, further restricting the rotation of the coil relative to the central column.
[0016] 3. The central column also has through holes, which extend through both sides of the central column in the radial direction and connect to the end of the gap away from the pressure cap. The through holes effectively create a rounded corner at the end of the gap away from the pressure cap. This enhances the deformation and expansion effect of the central column under the pressure of the insert block, and reduces stress concentration at the edges within the gap, thus lowering the risk of breakage at the edges when the central column deforms and expands under the pressure of the insert block.
[0017] The present invention also proposes another embodiment of an automated winding clamp, the automated winding clamp comprising: A sleeve, wherein the sleeve has a receiving cavity inside; A central column is disposed within the receiving cavity and rotates with the sleeve. A coil frame is sleeved on the outside of the central column. A first slot is also provided on the outside of the central column, which extends along the axial direction of the central column and is used to hold the coil frame. A pressure cap, which abuts against the end of the central column away from the sleeve and rotates with the central column, and is mounted on the movable tailstock of the winding machine; The two ends of the coil frame abut against the sleeve and the pressure cap, respectively; The end face of the sleeve is provided with a second slot, and the end face of the pressure cap is provided with a third slot. The width of the second slot and the third slot gradually decreases from shallow to deep. The second block and the third block located at both ends of the coil frame are respectively locked in the second slot and the third slot.
[0018] In an optional embodiment, the central post is transitionally fitted with the receiving cavity, and the automated winding clamp further includes a fixing member mounted on the sleeve and used to fix the central post on the sleeve. In an alternative embodiment, the fastener includes a screw that is threadedly connected to the sleeve and abuts against the central post to secure the central post to the sleeve.
[0019] In an alternative embodiment, the second slot and the third slot are respectively arranged around the central column.
[0020] Compared with the prior art, the present invention has the following technical effects: The automated winding clamp of this invention comprises a sleeve, a central post, and a pressure cap. The coil bobbin is fitted onto the outside of the central post, with its two ends abutting against the sleeve and pressure cap, respectively. A second slot is formed on the end face of the sleeve, and a third slot is formed on the end face of the pressure cap. The width of the second and third slots gradually decreases from shallow to deep. Second and third locking blocks located at both ends of the coil bobbin are respectively engaged within the second and third slots, clamping the coil bobbin radially. This prevents the coil bobbin from loosening during the winding process, thus ensuring the winding technique can be performed.
[0021] The pressure cap abuts against the end of the central column away from the sleeve and rotates with the central column. The two ends of the coil frame abut against the sleeve and the pressure cap respectively. The pressure cap, together with the sleeve, clamps the coil frame in the axial direction of the central column, further stabilizing the coil frame on the central column, and at the same time effectively suppressing the jumping of the end of the coil frame.
[0022] A first slot is also provided on the outer side of the central column, extending along the axis of the central column to the end opposite to the pressure cap. The first slot is used to hold the coil frame in place. When installing the coil frame, the first locking block of the coil frame is locked in the first slot, further restricting the rotation of the coil relative to the central column.
[0023] The central column does not require gaps or continuous compression to deform and expand, reducing the risk of fatigue failure caused by continuous deformation and expansion, thus resulting in a longer service life.
[0024] The automated winding clamp of the present invention has a simple structure, is easy to install, does not require too many parts, reduces the risk of failure, and has low design and manufacturing costs. Attached Figure Description

Example 1
[0031] Please refer to Figures 1-4 This invention proposes an automated winding clamp 100.
[0032] In this embodiment of the invention, the automated winding chuck 100 includes a sleeve 1, a central post 2, a pressure cap 3, and an insert block 4. The sleeve 1 has a receiving cavity 101 inside. The central post 2 is disposed within the receiving cavity 101 and rotates with the sleeve 1, and has a gap 201. The gap 201 extends radially through both sides of the central post 2 and axially through the end of the central post 2 away from the sleeve 1. The coil bobbin is sleeved on the outside of the central post 2. The pressure cap 3 abuts against the end of the central post 2 away from the sleeve 1 and rotates with the central post 2, and is mounted on the movable tailstock of the winding machine (not shown in the figure). The insert block 4 is mounted on the pressure cap 3 and housed within the gap 201 to open the central post 2 on both sides of the gap 201. The two ends of the coil bobbin abut against the sleeve 1 and the pressure cap 3, specifically, the two ends of the coil bobbin abut against the end faces of the sleeve 1 and the pressure cap 3, respectively.
[0033] Please refer to Figure 1 and Figure 3 The sleeve 1, the central column 2, and the pressure cap 3 are coaxially arranged. The width of the insert block 4 is greater than the width of the gap 201. The gap 201 is provided in the central column 2 so that when the insert block 4 is inserted into the gap 201, the two sides of the central column 2 deform and expand under the squeezing action of the insert block 4. The coil frame sleeved on the outside of the central column 2 is held against by the central column 2, and the central column 2 provides continuous radial tension force, so that the coil frame is firmly installed on the central column 2, avoiding the coil frame from loosening during the rotation winding process and making the winding technology impossible.
[0034] The pressure cap 3 abuts against the end of the central column 2 away from the sleeve 1 and rotates with the central column 2. The two ends of the coil frame abut against the sleeve 1 and the pressure cap 3 respectively. The pressure cap 3, together with the sleeve 1, clamps the coil frame in the axial direction of the central column 2, further stabilizing the coil frame on the central column 2, and at the same time effectively suppressing the jumping of the end of the coil frame.
[0035] The pressure cap 3 is mounted on the movable tailstock of the winding machine and moves along the axis of the central column 2 with the movable tailstock. When the movable tailstock drives the pressure cap 3 to disengage from the central column 2, the automated equipment can automatically remove the wound coil bobbin and reinstall a new coil bobbin. After the new coil bobbin is installed, the movable tailstock drives the pressure cap 3 to press against the end of the central column 2 away from the sleeve 1 and the coil bobbin again. The pressure cap 3 drives the insert block 4 to re-insert into the gap 201, thus starting the next winding cycle.
[0036] The movable tailstock can be pneumatic, such as using a cylinder to drive its movement, or electrically driven, such as using a motor and a lead screw. Both pneumatic and electrically driven tailstocks are conventional technologies, and their specific implementation methods will not be elaborated here.
[0037] Please refer to Figure 1 and Figure 3The pressure cap 3 is provided with a first connecting part 301, and is rotatably mounted on the movable tailstock of the winding machine through the first connecting part 301. The first connecting part 301 can be a first mounting hole, using a rotating shaft (not shown in the figure), with one end of the rotating shaft installed in the first mounting hole and the other end of the rotating shaft installed in a bearing (not shown in the figure), which is installed on the movable tailstock, so that the pressure cap 3 is rotatably mounted on the movable tailstock. Alternatively, one end of the pressure cap 3 opposite to the central column 2 can be directly mounted on a bearing, which is installed on the movable tailstock, so that the pressure cap 3 is rotatably mounted on the movable tailstock.
[0038] The sleeve 1 has a second connecting part 102 at one end opposite the pressure cap 3, and is mounted on the main shaft of the winding machine (not shown in the figure) through the second connecting part 102. The second connecting part 102 can be a second mounting hole, through which the sleeve 1 is mounted on the main shaft of the winding machine. Alternatively, the outer side of the sleeve 1 can be clamped by a chuck (not shown in the figure), and the sleeve 1 can be mounted on the chuck.
[0039] A first slot 202 is also provided on the outer side of the central column 2, and the first slot 202 extends through both ends of the central column 2 along the axial direction of the central column 2. The first slot 202 is used to hold the coil frame. When installing the coil frame, the first locking block of the coil frame (not shown in the figure) is locked in the first slot 202, further restricting the rotation of the coil relative to the central column 2.
[0040] The center post 2 is fitted into the receiving cavity 101. The automated winding chuck 100 also includes a fixing member 5, which is mounted on the sleeve 1 and used to fix the center post 2 onto the sleeve 1 so that the center post 2 rotates with the sleeve 1. The center post 2 is fitted into the receiving cavity 101 so that the center post 2 can move along the axis of the sleeve 1 within the receiving cavity 101, facilitating adjustment of the length of the center post 2 extending outside the sleeve 1 to accommodate coil bobbins of different lengths. Specifically, the sleeve 1 has a threaded hole in the radial direction, which communicates with the receiving cavity 101. The fixing member 5 includes a screw, which is threadedly connected to the sleeve 1 through the threaded hole and abuts against the center post 2 to fix the center post 2 onto the sleeve 1.
[0041] Please refer to Figure 3 and Figure 4 The central column 2 also has a through hole 203, which extends through both sides of the central column 2 in the radial direction and connects to the end of the gap 201 away from the pressure cap 3. The through hole 203 is provided to be equivalent to a rounded corner at the end of the gap 201 away from the pressure cap 3. This can enhance the effect of the central column 2 deforming and opening under the pressure of the insert block 4, and reduce stress concentration at the edges in the gap 201, thereby reducing the risk of the edges in the gap 201 breaking when the central column 2 deforms and opens under the pressure of the insert block 4.
[0042] The gap 201 has a chamfer 200 at the end near the pressure cap 3, and the insert 4 also has a chamfer 200 at the end away from the pressure cap 3. The two chamfers 200 can serve as guides to facilitate the insertion of the insert 4 into the gap 201.
[0043] In the specific application of this application, the pressure cap 3 is mounted on the movable tailstock of the winding machine and moves along the axis of the central column 2 with the movable tailstock. When the movable tailstock moves away from the central column 2, causing the pressure cap 3 to disengage from the central column 2, the automated equipment can automatically remove the wound coil bobbin and reinstall a new coil bobbin. After the new coil bobbin is installed, the movable tailstock causes the pressure cap 3 to press against the end of the central column 2 away from the sleeve 1 and the coil bobbin again. The pressure cap 3 then causes the insert block 4 to re-insert into the gap 201, thereby starting the next winding cycle.
[0044] During the insertion of the insert 4 into the gap 201, the central column 2 deforms and expands on both sides of the gap 201 under the squeezing action of the insert 4. The coil frame, which is sleeved on the outside of the central column 2, is held in place by the central column 2, and the central column 2 provides continuous radial tension, thereby ensuring that the coil frame is securely installed on the central column 2 and preventing the coil frame from loosening during the rotation winding process, which would prevent the winding technique from being carried out. The pressure cap 3 abuts against the end of the central column 2 away from the sleeve 1 and rotates with the central column 2. The two ends of the coil frame abut against the sleeve 1 and the pressure cap 3 respectively. The pressure cap 3, together with the sleeve 1, clamps the coil frame in the axial direction of the central column 2, further stabilizing the coil frame on the central column 2, and also effectively suppressing the jump at the end of the coil frame. Example 2
[0045] Please refer to Figures 5-7 In this embodiment, the automated winding chuck 100 includes: Sleeve 1, with a receiving cavity 101 inside.
[0046] The central column 2 is located inside the receiving cavity 101 and rotates with the sleeve 1. The coil frame is sleeved on the outside of the central column 2. A first slot 202 is also provided on the outside of the central column 2. The first slot 202 extends along the axial direction of the central column 2 and is used to hold the coil frame.
[0047] The pressure cap 3 abuts against the end of the central column 2 away from the sleeve 1 and rotates with the central column 2, and is installed on the movable tailstock of the winding machine.
[0048] The two ends of the coil frame abut against the sleeve 1 and the pressure cap 3, respectively.
[0049] The end face of the sleeve 1 is provided with a second slot 103, and the end face of the pressure cap 3 is provided with a third slot 302. The width of the second slot 103 and the third slot 302 gradually decreases from shallow to deep. The second and third blocks located at both ends of the coil frame are respectively locked in the second slot 103 and the third slot 302.
[0050] Compared with Example 1, the central column 2 in this example is a column, and the coil frame is not fixedly mounted on the central column 2 by deforming and expanding the central column 2.
[0051] Therefore, this embodiment does not use the insert block 4, and the central column 2 does not have a gap 201, thus eliminating the need for a through hole 203 to reduce stress concentration at the edges within the gap 201. Obviously, there is also no need to design a chamfer 200 in the gap 201 or the insert block 4.
[0052] Please refer to Figure 5 and Figure 6 The two ends of the coil frame abut against the sleeve 1 and the pressure cap 3, respectively, and the two ends of the coil frame abut against the end faces of the sleeve 1 and the pressure cap 3, respectively. In this embodiment, the end face of the sleeve 1 is further provided with a second slot 103, and the end face of the pressure cap 3 is further provided with a third slot 302. The widths of the second slot 103 and the third slot 302 gradually decrease from shallow to deep. The second and third locking blocks at both ends of the coil frame are respectively locked in the second slot 103 and the third slot 302, clamping the coil frame in the radial direction through the second slot 103 and the third slot 302.
[0053] Both the second slot 103 and the third slot 302 are V-shaped slots, so that the width of the second slot 103 and the third slot 302 gradually decreases from shallow to deep. The shapes of the second and third blocks located at both ends of the coil frame are adapted to the shapes of the second slot 103 and the third slot 302, and the overall size of the second and third blocks is larger than the overall size of the second slot 103 and the third slot 302, so that the second slot 103 and the third slot 302 can lock the second and third blocks, preventing the second and third blocks from loosening, thereby clamping the second and third blocks in the radial direction.
[0054] In practice, based on experience or design and manufacturing requirements, the overall size of the second and third locking blocks can be 1.1 to 1.5 times the overall size of the second slot 103 and the third slot 302, but it is not limited to this. As long as the second slot 103 and the third slot 302 can lock the second and third locking blocks and prevent the second and third locking blocks from becoming loose, it is acceptable.
[0055] Please refer to Figure 5 and Figure 6 The second slot 103 and the third slot 302 are respectively arranged around the central column 2, which can increase the contact area between the second slot 103 and the second card block and the contact area between the third slot 302 and the third card block, and make the radial clamping force on the second card block and the third card block more balanced.
[0056] In summary, this embodiment uses a second slot 103 and a third slot 302 to respectively hold the second and third locking blocks located at both ends of the coil frame, preventing the second and third locking blocks from loosening, thereby clamping the second and third locking blocks in the radial direction. Instead of designing a gap 201 in the central column 2 as in Embodiment 1, and using an insert block 4, during the insertion of the insert block 4 into the gap 201, the central column 2 deforms and expands on both sides of the gap 201 under the squeezing action of the insert block 4. The coil frame, sleeved on the outside of the central column 2, is held in place by the central column 2, and the central column 2 provides continuous radial tension, thus ensuring the coil frame is securely mounted on the central column 2.
[0057] Compared to Example 1, the central column 2 in this example does not need to have a gap 201, nor does it need to be continuously compressed and deformed, reducing the risk of fatigue failure caused by continuous deformation and thus resulting in a longer service life.
[0058] Apart from the different technical solutions mentioned above, the other technical solutions in Embodiment 2 are the same as those in Embodiment 1, and will not be repeated here.
[0059] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
