Precise parameter control allows the same equipment to be compatible with both adhesive and non-adhesive coils.

Description

Technical Field

[0001] This utility model belongs to the technical field of winding machine, and specifically relates to a desizing structure for a winding machine. Background Technology

[0002] The unloading structure of a winding machine is a key component in coil production, and its performance directly affects unloading efficiency and the quality of the finished coil. Current technologies generally employ cylinder-driven core-pulling unloading, which has significant shortcomings: low drive control precision: the output force and stroke adjustment range of the cylinder are narrow, making it difficult to flexibly adjust parameters according to coil specifications, easily leading to large impacts and poor stability during the unloading process; traditional cylinder-driven modes cannot accommodate the differentiated needs of two types of coils, often requiring the replacement of specialized equipment or components; reliability and yield issues: uncontrollable unloading actions can easily cause coil deformation, breakage, or residue, especially significantly impacting the yield of high-precision coils (such as miniature inductors). Although some solutions attempt to optimize the mechanical structure, the rigidity inherent in the power source itself limits the fundamental solutions to these problems, hindering the versatility and intelligent upgrading of winding equipment. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides a descrambling structure for a winding machine, which aims to solve the problem of uncontrollable coil descrambling.

[0005] (2) Technical solution

[0006] This utility model provides a descrambling structure for a winding machine, including a first driving member. The first driving member extends downward with a lead screw and a nut seat sleeved on the lead screw. At least one side of the nut seat is connected to a connecting assembly. A rotating shaft is provided below the connecting assembly, with corresponding vertical rotation shafts. The rotating shaft is connected to a rotating assembly that drives the rotating shaft to rotate. A central column is also provided inside the rotating shaft. One end of the central column is rotatably connected to the connecting assembly, and the other end passes through the rotating shaft and is provided with a winding part. A coil is wound around the outer peripheral wall of the winding part.

[0007] During unloading, the first driving component drives the nut seat to reciprocate vertically, simultaneously causing the connecting assembly and the central column to move vertically relative to the rotating axis to pull the core, and the coil disengages from the winding part.

[0008] Furthermore, the connecting assembly includes a first connecting seat and a second connecting seat, with a fixing member between them. The upper end of the fixing member is connected to the second connecting seat, and the bottom end is rotatably connected to the central column.

[0009] Furthermore, the first connecting seat is provided with grooves corresponding to the upper and lower parts of the fixing member, and the end of the central column connected to the fixing member is provided with a protrusion, which is snapped into the groove.

[0010] Furthermore, the fixing member is provided with an outwardly extending platform, and a first bearing is provided between the platform and the second connecting seat. The first bearing is a planar thrust bearing.

[0011] Furthermore, the rotating shaft is fitted with a detachable bearing housing, and the bearing housing has a boss inside. The boss has two bearing grooves on both sides along its axial direction, and the two bearing grooves are respectively provided with a second bearing and a third bearing.

[0012] Furthermore, the second bearing is a deep groove ball bearing, and the third bearing is an angular contact ball bearing.

[0013] Furthermore, the rotating shaft is provided with a wire clamping component, which includes a rotating shaft, an "L"-shaped connecting rod that connects the rotating shaft and passes laterally through the central column, and a clamp disposed at the end of the connecting rod, the clamp acting on the coil.

[0014] Furthermore, a vertically spring-loaded elastic element is provided between the connecting rod and the rotating shaft.

[0015] Furthermore, the rotating assembly includes a second transmission component, a belt, a second drive component, and a first transmission component connected to the second drive component, all sleeved on the rotating shaft. The belt simultaneously sleeves the second transmission component and the first transmission component.

[0016] Furthermore, at least one air outlet is provided on one side of the winding section, and the air outlet has built-in cold or hot air.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Digital control of the motor allows for real-time adjustment of the unloading stroke, speed, and output force, adapting to the unloading needs of coils with different wire diameters, materials, and types, thus solving the problem of unadjustable cylinder drive parameters. Precise parameter control enables the same equipment to be compatible with both adhesive and non-adhesive coils. The smoothness of the motor drive significantly reduces unloading impact, preventing coil deformation or damage, ensuring the molding stability of adhesive coils, and comprehensively improving the yield rate. The motor system has a longer lifespan and lower failure rate than the cylinder, and requires no air source equipment, simplifying the overall structure and reducing energy consumption.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-3As shown, this utility model provides a winding machine unloading structure, including a bracket and a first driving component 1 fixed on the bracket. The first driving component 1 is a motor, whose output axis extends downward to form a lead screw 11. The lead screw 11 has an external thread and is fitted with a nut seat 12 that can move along its axis. Two sets of symmetrically arranged connecting components 2 are fixedly connected to both sides of the nut seat 12. At a certain distance below the connecting components 2, there are rotating shafts 3 arranged vertically and vertically. Each rotating shaft 3 is connected to a rotating component 5 that drives its rotation. The rotating shaft 3 is designed as a hollow structure, and its interior has a central column 4 that can slide up and down along its axis. The upper end of the central column 4 extends and is rotatably connected to the corresponding connecting component 2, so that the central column 4 can rotate relative to the connecting component 2. The lower end of the central column 4 extends downward and passes through the rotating shaft 3. Its protruding part has a winding part 41, and a coil 42 is wound on the winding part 41.

[0034] In use, the fixed first driving component 1 drives the lead screw 11 to rotate, causing the nut seat 12 to move upward along the lead screw 11. The nut seat 12 simultaneously drives the connecting components 2 on both sides and the two central columns 4 connected to them to move upward. At this time, the rotating shaft 3 remains fixed in the axial direction, and the central column 4 slides upward relative to the rotating shaft 3. As the central column 4 moves upward, the winding part 41 at its lower end gradually retracts into the rotating shaft 3. At the same time, the coil 42 wound around the winding part 41 cannot move upward due to the obstruction at the bottom of the rotating shaft 3. Finally, when the winding part 41 is completely retracted into the rotating shaft 3, the coil 42 is disengaged from the winding part 41, thereby realizing the core extraction and unloading of the coil 42.

[0035] Most winding machines on the market use a cylinder to drive the central column 4 for core pulling during unloading. However, the unloading mechanism of these winding machines is only suitable for either adhesive or non-adhesive coils. Using a cylinder for unloading often has some drawbacks: the output force and stroke of the cylinder are uncontrollable, the adjustment range is narrow, and the operation is not smooth. Furthermore, the uncontrollable cylinder cannot be adjusted to be suitable for both adhesive and non-adhesive coils. To solve this problem, this application replaces the traditional cylinder with the first driving component 1, i.e., a motor. The controllability of the motor enables precise adjustment of position, speed, and force during the unloading process. At the same time, the speed and output force of the motor can be adjusted in real time through the control system, flexibly matching the unloading requirements of different specifications and types (adhesive and non-adhesive) coils.

[0036] Specifically, such as Figure 4-5As shown, in one embodiment of this utility model, the connecting component 2 is composed of a first connecting seat 21 and a second connecting seat 22, both arranged in an "L" shape at the top and bottom. The size of the first connecting seat 21 is larger than that of the second connecting seat 22. The vertical part of the first connecting seat 21 is fixedly screwed to the nut seat 12. The vertical part of the second connecting seat 22 is fixedly connected to the side end of the vertical part of the first connecting seat 21. The horizontal parts of the two connecting seats are arranged vertically and horizontally. A fixing member 23 is provided between the two horizontal parts. The upper end of the fixing member 23 passes through the horizontal part of the second connecting seat 22 and is fixedly connected to it. Its bottom end is rotatably connected to the central column 4. Since the fixing member 23 is axially fixed through the second connecting seat 22, when the central column 4 is driven by the rotating component 5 to rotate, it can rotate relative to the fixing member 23. The above structural design ensures that when the nut seat 12 is driven by the first driving member 1 to move up and down, it can synchronously drive the first connecting seat 21, the second connecting seat 22, the fixing member 23 and the central column 4 to perform an overall lifting and lowering movement.

[0037] Furthermore, such as Figure 5 As shown, the first connecting seat 21 has a groove 211 in its transverse portion. The groove 211 is coaxially arranged with the fixing member 23 and the central column 4. As shown, the end of the central column 4 that connects to the fixing member 23 has an outwardly extending protrusion 43. The connection point (including a part of the fixing member 23 and the protrusion 43) is accommodated in the groove 211. Since the central column 4 needs to continuously rotate relative to the fixing member 23, placing the rotating mating part (connection point) in the groove 211 can effectively isolate external dust and other contaminants from intruding, avoiding affecting the... Regarding the rotational performance of the central column 4, as shown in the figure, the protrusion 43 and the groove 211 form a snap-fit ​​engagement. However, during the operation of the mechanism, the central column 4 mainly bears the axial tensile force (upward) from the fixing member 23, and the downward pressure applied to the bottom of the groove 211 is minimal. Therefore, the continuous rotation of the central column 4 will not cause significant wear to the bottom of the groove 211. The main purpose of this snap-fit ​​structure is that even if the central column 4 is accidentally loosened, the protrusion 43 can still be constrained by the groove 211 to prevent it from falling off completely, thereby reducing the risk of damage.

[0038] Furthermore, such as Figure 5As shown, the lower side of the fixing member 23 is provided with an outwardly extending platform 231. A first bearing 24 is installed between the platform 231 and the transverse portion of the second connecting seat 22. The first bearing 24 is sleeved on the fixing member 23. The first bearing 24 is a planar thrust bearing, which is designed to bear axial (i.e., vertical) loads in this structure. As shown, when the nut seat 12 drives the connecting assembly 2 and the central column 4 to move upward, the central column 4 will apply an upward axial thrust to the fixing member 23. The position of the first bearing 24 enables it to effectively bear and disperse this thrust, significantly reducing the local stress concentration in the contact area between the fixing member 23 and the second connecting seat 22.

[0039] Specifically, such as Figure 6-8 As shown, in one embodiment of this utility model, the rotating shaft 3 is fitted with a bearing housing 6. The bearing housing 6 contains a boss 61 extending towards the rotating shaft 3. Two independent bearing grooves 62 are formed on both axial (i.e., vertical) sides of the boss 61. A second bearing 63 is installed in the upper bearing groove 62, and a third bearing 64 is installed in the lower bearing groove 62. The second bearing 63 is a deep groove ball bearing, and the third bearing 64 is an angular contact ball bearing. Both types of bearings can withstand radial and axial forces. This arrangement effectively disperses the radial force generated by the rotation of the rotating shaft 3, while simultaneously bearing… The bearing 63 is a pair of second bearings (deep groove ball bearings) installed in the upper bearing groove 62 to receive and disperse the axial force generated when the central column 4 slides axially (vertically) relative to the rotating shaft 3. Similarly, two third bearings (angular contact ball bearings) are installed in pairs in the lower bearing groove 62 to receive and disperse the axial force generated when the central column 4 slides axially (vertically) relative to the rotating shaft 3. Each angular contact ball bearing mainly bears the axial force in one direction. By arranging them in pairs (back to back), the two angular contact ball bearings work together to bear the axial force in both directions. This paired installation method significantly improves the upper limit of the axial load capacity of the bearing assembly as a whole.

[0040] It is worth noting that the inner hole of the boss 61 of the bearing housing 6 maintains a gap with the outer surface of the rotating shaft 3 and does not directly contact it. The only parts that directly cooperate with the rotating shaft 3 are the inner rings of the second bearing 63 and the third bearing 64. The core function of the boss 61 is to separate and position the upper and lower sets of bearings so that they maintain a specific axial distance. This design effectively increases the span of the rotating shaft 3 support system, thereby significantly improving the running concentricity and overall rigidity of the rotating shaft 3.

[0041] Specifically, such as Figure 9-10As shown in one embodiment of this utility model, a wire clamping member 31 is provided on the lower end of the rotating shaft 3 near the winding part 41 and the coil 42. The wire clamping member 31 is composed of a rotating shaft 311, an "L"-shaped connecting rod 312, and a clamp 313. As shown in the figure, one end of the horizontal portion of the "L"-shaped connecting rod 312 is connected to the rotating shaft 311, and the other end extends horizontally and passes through the horizontal through hole provided on the central column 4, and then extends downward. Its vertical extension end is provided with an arc-shaped clamp 313. The clamp 313 has a clamping groove for clamping the wire end of the coil 42. The horizontal through hole provided on the central column 4 has a vertical height dimension greater than the diameter (or thickness) of the horizontal portion of the connecting rod 312. In the un-unwinding state (i.e., the initial or winding completed state), When the coil 42 is wound on the winding part 41, the upper wall of the through hole abuts against the upper surface of the transverse part of the connecting rod 312, while a gap is reserved between the lower wall of the through hole and the lower surface of the transverse part of the connecting rod 312. When the coil 42 is wound on the winding part 41, the clamp 313 has not yet clamped the end of the coil wire. When the clamping action needs to be performed, the first driving member 1 is controlled to drive the central column 4 to move downward a small distance. During this process, since the transverse part of the connecting rod 312 is initially restricted by the upper wall of the through hole, the downward movement of the central column 4 will exert a downward force on the transverse part of the connecting rod 312 through the upper wall of the through hole. This force is transmitted to the connecting rod 312, driving it to rotate around the rotating shaft 311, and finally driving the clamp 313 to clamp the end of the coil 42.

[0042] Furthermore, a vertically installed elastic element (such as a spring) is provided between the lower end of the lateral portion of the connecting rod 312 and the rotating shaft 3. In the initial state (before unloading): the elastic element is in a pre-compressed state, and its restoring force applies a continuous upward thrust to the lateral portion of the connecting rod 312. When the central column 4 is driven upward by the first driving member 1 to unload, since the central column 4 no longer constrains the connecting rod 312 through the upper wall of the through hole, the compressed elastic element can extend and reset. The extension and reset force of the elastic element acts on the connecting rod 312, driving the connecting rod 312 to rotate (oscillate) upward around the rotating shaft 311. This rotation directly drives the chuck 313 at the lower end of the connecting rod 312 to lift up and move away from the wire end of the coil 42, thereby achieving reliable disengagement of the chuck 313 from the wire end.

[0043] Specifically, such as Figure 11As shown, in one embodiment of this utility model, the rotating assembly 5 includes: a transmission component 51: mounted on each rotating shaft 3, a belt 52, and a second drive component 53: typically a motor. The two rotating shafts 3 are arranged in parallel. The second drive component 53 is located on one side between the two rotating shafts 3. The belt 52 simultaneously surrounds the output wheel of both transmission components 51 and the second drive component 53. When the second drive component 53 is running, it synchronously drives the two transmission components 51 to rotate in the same direction through the belt 52. The transmission component 51 directly transmits the rotational motion to its corresponding rotating shaft 3, thereby realizing the function of a single drive component simultaneously driving the rotation of both rotating shafts 3.

[0044] Specifically, such as Figure 12 As shown, in one embodiment of this utility model, each winding portion 41 is provided with two air outlets 7 on one side: one for outputting hot air and the other for outputting cold air. When manufacturing the adhesive coil, the air outlet 7 that outputs hot air is first controlled to blow hot air onto the wound coil 42. The hot air melts the adhesive on the coil 42, melting and bonding each coil turn into a whole. Subsequently, the air outlet 7 that outputs cold air blows cold air onto the coil 42. The cold air cools and solidifies the molten adhesive quickly, thereby firmly fixing the coil 42 in the wound state. Since the melting and bonding process causes the coil 42 to stick to the surface of the winding portion 41, at this time, the first driving member 1 needs to be controlled to drive the central column 4 to move upward. The upward movement of the central column 4 drives the winding portion 41 to be pulled out from the solidified coil 42, realizing the final core removal and material removal.

[0045] The working principle of this utility model will be explained in detail below:

[0046] During the winding stage, the first driving member 1 applies a downward force to the central column 4, and the central column 4 applies a downward force to the wire clamping member 31, so that the clamp 313 of the wire clamping member 31 can clamp the wire end of the coil 42 (at this time, the coil 42 is not wound). Then, the rotating component 5 drives the rotating shaft 3 and the central column 4 to rotate synchronously, so that the coil 42 is wound into a spiral inductor coil in the winding part 41. After the winding is completed, it is moved to the welding table (not shown). At this time, the unloading stage begins. The first driving member 1 operates, driving the nut seat 12 and the connecting component 2 to move upward along the lead screw 11, and synchronously driving the central column 4 to move upward to pull the core. The winding part 41 moves upward and retracts into the rotating shaft 3. The coil 42 separates from the winding part 41 and enters the welding table for welding.

[0047] The innovation of this utility model lies in:

[0048] Replacing traditional cylinders with motor-driven systems overcomes existing technological bottlenecks, offering the following specific benefits: Precise and controllable unloading: Digital control of the motor (the primary driving component) allows for real-time adjustment of unloading stroke, speed, and output force, adapting to the unloading needs of coils with different wire diameters, materials, and types, thus solving the problem of unadjustable cylinder drive parameters; Enhanced equipment versatility: Precise parameter control enables the same equipment to be compatible with both adhesive and non-adhesive coils—low-speed, gentle unloading is used for adhesive coils to avoid adhesion, while high-speed, high-force unloading is used for non-adhesive coils to improve efficiency and significantly reduce changeover costs; Optimized production quality and efficiency: The smoothness of motor drive greatly reduces unloading impact, preventing coil deformation or damage. Combined with hot / cold air curing modules (air outlets), it further ensures the molding stability of adhesive coils, comprehensively improving yield; Reduced maintenance costs: Motor systems have a longer lifespan and lower failure rate than cylinders, and require no air source equipment, simplifying the overall structure and reducing energy consumption.
