Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a wire winding rocker arm device. Background Technology

[0002] In the production of wires and cables, neatly winding continuously produced wires is a crucial subsequent process. Existing technologies typically employ complex rocker arm mechanisms for wire end transfer. For example, some equipment uses multi-axis robotic arms, which are costly and complex to control; others use separate wire clamps and transfer mechanisms for separate winding, resulting in a bulky overall structure and long rewinding cycles. Furthermore, after the wire is cut, the wire end tends to retract within the rocker arm's feed rod, making it difficult to accurately reach the clamping position on the empty reel during subsequent delivery, leading to rewinding failures, requiring manual intervention, and impacting production efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire winding rocker arm device, which can effectively prevent the wire end from retracting, while also clamping the wire to prevent it from loosening. It has a simple structure and an efficient and rapid winding process.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wire winding rocker arm device, comprising:

[0006] The rocker arm mechanism includes a hollow rocker arm wire feed rod and a first drive structure for driving the rocker arm wire feed rod to move back and forth.

The wire passes through the clamping block structure and then enters the rocker arm wire feeding rod. The third driving structure is used to drive the clamping block structure to clamp the wire located therein.

[0009] A side-pushing mechanism is used to push the rocker arm wire feed rod in the left-right direction. The side-pushing mechanism includes a side-pushing structure disposed on one side of the outlet end of the rocker arm wire feed rod and a fourth driving structure for moving the side-pushing structure in the left-right direction.

[0012] According to some embodiments of the present invention, the push structure includes a top plate disposed on the lower side of the outlet end near the rocker arm feed rod, and the second drive structure is disposed below the top plate and connected to the side end of the top plate away from the push structure.

[0013] According to some embodiments of the present invention, the side-pushing mechanism further includes a reset structure disposed on the base, the reset structure being used to push and reset the rocker arm feed rod that has been pushed laterally by the first push plate.

[0017] According to some embodiments of the present invention, the clamping block structure includes an L-shaped clamp and a clamping block arranged opposite to each other, and the third driving structure can drive the clamping block to move towards the L-shaped clamp to clamp the wire passing between the two.

[0018] This utility model has at least the following beneficial effects:

It also allows the side-pushing structure to avoid interference when the rocker arm wire feeder needs to be pushed, facilitating operations such as wire cutting. By directly mounting the wire clamping mechanism on the rocker arm mechanism, the entire device structure becomes more compact, effectively preventing the wire end from retracting during the hooking process and avoiding winding failures caused by retraction or swaying. This greatly improves the success rate and reliability of automatic reel changing. Attached Figure Description

[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a wire winding rocker arm device, such as... Figure 1-2 As shown, it includes:

[0029] The rocker arm mechanism 1 includes a hollow rocker arm wire feed rod 101 and a first drive structure 102 for driving the rocker arm wire feed rod 101 to move back and forth. The wire 5 to be wound enters from the inlet end 103 of the rocker arm wire feed rod 101 and extends from the outlet end 104 of the rocker arm wire feed rod 101.

[0030] The swing mechanism 2 includes a push structure 201 for abutting against the bottom of the rocker arm wire feed rod 101 and a second drive structure 202 for moving the push structure 201 up and down.

[0031] The wire clamping mechanism 3 is mounted on the rocker arm mechanism 1. The wire clamping mechanism 3 includes a clamping block structure 301 mounted on one side of the inlet end 103 of the rocker arm wire feeding rod 101 and a third drive structure 302. The wire 5 passes through the clamping block structure 301 and then enters the rocker arm wire feeding rod 101. The third drive structure 302 is used to drive the clamping block structure 301 to clamp the wire 5 located therein.

[0032] The side push mechanism 4 is used to push the rocker arm wire feed rod 101 in the left and right direction. The side push mechanism 4 includes a side push structure 401 disposed on one side of the outlet end 104 of the rocker arm wire feed rod 101 and a fourth drive structure 402 for moving the side push structure 401 in the left and right direction.

[0033] The wire 5 to be wound enters from the inlet end 103 of the rocker arm feed rod 101, extends from its outlet end 104, and is then fed into the winding equipment (not shown in the diagram) for winding and packaging of the wire 5. The rocker arm feed rod 101 is a guide component for the wire 5. The first drive structure 102 is used to drive the entire rocker arm feed rod 101 to reciprocate along its axial direction. The first drive structure 102 can be a ball screw pair driven by a servo motor, or it can be a cylinder, hydraulic cylinder, or electric push rod, etc. Its function is to drive the rocker arm feed rod 101 forward and backward during winding. Driving the rocker arm feed rod 101 forward so that the end of the wire 5 is hooked by the structure in the winding equipment, and driving the rocker arm feed rod 101 backward so that the rocker arm feed rod 101 is reset, and then the next round of winding continues.

[0034] The swing mechanism 2 is used to realize the up-and-down movement of the rocker arm wire feeder 101 during the winding process, cooperating with the winding device in front to make the wire 5 move up and down evenly and wind. The push structure 201 abuts against the bottom of the rocker arm wire feeder 101. The second drive structure 202 drives the push structure 201 to push from the bottom to the top, so that the rocker arm wire feeder 101 moves up and down. This push method is simple and effective, and convenient for maintenance and replacement. In addition, the push structure 201 can act as a support when the rocker arm wire feeder 101 moves back and forth. The second drive structure 202 can be a cylinder or a servo electric cylinder, which drives the push structure 201 to make vertical lifting and lowering movements. When the push structure 201 rises, it lifts the outlet end 104 side of the rocker arm wire feeder 101. In this embodiment, the rocker arm wire feeder 101 is fixed at the inlet end 103 side by a hinge fulcrum to form a lever structure, so that the outlet end 104 can swing up and down to realize the upward swinging action of the rocker arm wire feeder 101. When the jacking structure 201 descends, the rocker arm feed rod 101 returns to a horizontal position under its own weight.

[0035] The wire clamping mechanism 3 is directly mounted on the rocker arm mechanism 1, allowing it to move together with the rocker arm wire feed rod 101 as it moves back and forth, maintaining the clamping of the wire 5 and preventing the wire 5 from coming loose when the winding device hooks the wire. The clamping block structure 301 is located on one side of the inlet end 103, with a tight structure and good clamping effect. The clamping block structure 301 can be a pair of V-shaped jaws, left and right clamping blocks, or other clamping structures driven by a third drive structure 302 such as a cylinder to perform clamping or releasing actions. The wire 5 passes through the middle of it and then enters the inner hole of the rocker arm wire feed rod 101.

[0036] The side-pushing mechanism 4 is located on one side of the outlet end 104 of the rocker arm wire feed rod 101. When the rocker arm wire feed rod 101 moves up and down, it does not interfere with other structures. When side-pushing is required, the fourth drive structure 402 pushes the outlet end 104 of the rocker arm wire feed rod 101 in the left and right direction. At this time, the rocker arm wire feed rod 101 slides directly on the top-pushing structure 201 to provide support.

[0037] The rocker arm device operates as follows:

[0038] Normal winding state: The clamping mechanism 3 is in the loose state. The wire 5 passes through the clamping block structure 301, enters from the inlet end 103 of the rocker arm wire feed rod 101, extends out from the outlet end 104 and is wound on the rotating reel. The second drive structure 202 drives the rocker arm wire feed rod 101 to swing up and down at a uniform speed, so that the wire 5 is neatly arranged on the reel.

[0039] In the middle state of changing the coil: When a coil of wire 5 is fully wound, the second drive structure 202 stops swinging, and the fourth drive structure 402 drives the side push structure 401 to push the rocker arm wire feed rod 101 to the left or right. The wire cutting structure in the winding device clamps the wire 5 and cuts it. Then, the rocker arm wire feed rod 101 is driven to reset to the right or left.

[0040] Wire feeding state: The third drive structure 302 drives the clamping block structure 301 to clamp the wire 5. Then, the first drive structure 102 drives the entire rocker arm mechanism 1 to move forward to feed the wire 5 at the outlet end 104 of the rocker arm wire feeding rod 101 to the hook structure of the winding device. Finally, the first drive structure 102 drives the entire rocker arm mechanism 1 to move backward to reset. At the same time, the third drive structure 302 drives the clamping block structure 301 to release the wire 5. Then, the device returns to the normal winding state and enters the next working cycle.

[0041] In some embodiments, such as Figure 2 As shown, the rocker arm mechanism 1 also includes a rotatable base 105, one side of the inlet end 103 of the rocker arm wire feed rod 101 is hinged to the base 105, and the wire clamping mechanism 3 is fixed to the base 105.

[0042] During normal winding, the inlet end 103 of the rocker arm wire feed rod 101 is hinged to the base 105, which enables the outlet end 104 of the rocker arm wire feed rod 101 to swing up and down. The hinged connection makes the wire inlet movement on the inlet end 103 side of the rocker arm wire feed rod 101 smaller, avoiding the situation where the wire gets stuck due to the rocker arm wire feed rod 101 swinging up and down as a whole. The base 105 integrates and fixes the rocker arm feed rod 101, the wire clamping mechanism 3, and other structures that need to rotate or move back and forth together. This allows the outlet end 104 of the rocker arm feed rod 101 to swing left and right during reel changing, causing the entire base 105 on the inlet end 103 side to rotate together. This synchronously adjusts the direction of the feed rod and the wire clamping mechanism 3, preventing the rocker arm feed rod 101 from colliding with other structures or causing other pulling effects on the wire 5, reducing damage caused by relative displacement. Other structures can maintain a relatively stable distance from the rocker arm feed rod 101, improving clamping accuracy and preventing changes in their relative positions due to the left and right movement of the rocker arm feed rod 101. The base 105 can rotate using a rotating plate in conjunction with a slewing bearing or other rotating structures, or it can be additionally equipped with a servo motor or a limiting structure to limit the rotation distance.

[0043] Furthermore, such as Figure 2-3 As shown, the side push structure 401 includes a first push plate 403 disposed on one side near the outlet end 104 of the rocker arm wire feed rod 101 and a first limiting rod 404 disposed on the other side of the rocker arm wire feed rod 101 opposite to the first push plate 403.

[0044] The fourth drive structure 402 can apply force to the push plate on one side to make the rocker arm wire feed rod 101 move laterally. The first limit rod 404 prevents excessive displacement and avoids excessive deflection of the rocker arm wire feed rod 101. The structure is simple, reliable and low cost.

[0045] Furthermore, such as Figure 1 , 5 As shown, the push structure 201 includes a top plate 203 disposed on the lower side of the outlet end 104 near the rocker arm feed rod 101, and a second drive structure 202 disposed below the top plate 203 and connected to the side end of the top plate 203 away from the side push structure 401.

[0046] The top plate 203 is a flat plate structure with a smooth top. When the first push plate 403 pushes the rocker arm feed rod 101, it can slide directly on the top plate 203, cooperating to complete the side pushing operation, reducing unnecessary additional structures. The second drive structure 202 and the side pushing structure 401 are staggered to avoid interference with each other. At the same time, since the second drive structure 202 is fixed to the top plate 203 through its own vertically moving connecting rod 204, the fixing will be as follows: Figure 5 As shown, there is a connecting rod 204 that is higher than the top surface of the top plate 203. Since the connecting rod 204 is fixed on the side away from the push plate structure, this connecting rod 204 can be directly used as the first limiting rod 404. When the first push plate 403 pushes the rocker arm wire feeding rod 101 excessively, it is directly blocked by the connecting rod 204 to prevent damage caused by excessive pushing. This also reduces the need for additional first limiting rods 404, further reducing equipment costs.

[0047] Furthermore, such as Figure 2-4 As shown, the side push mechanism 4 also includes a reset structure 405 disposed on the base 105. The reset structure 405 is used to push and reset the rocker arm wire feed rod 101 that is pushed laterally by the first push plate 403.

[0048] Because the overall structure of the device at the first push plate 403 is quite complex, if a reset push plate were installed, it would also require a corresponding drive structure, limit rod, and other structures, which would be space-constrained. Therefore, a reset structure 405 is installed on the base 105. After the first push plate 403 completes the lateral push of the wire and releases the force, the reset structure 405 can directly act on the rocker arm wire feed rod 101, causing the rocker arm wire feed rod 101 to quickly return to the center. More importantly, if... Figure 4 As shown, during the wire feeding state, the reset structure 405 also remains in a clamping state, which improves the stability of the entire rocker arm wire feeding rod 101 and prevents the swinging inlet end 103 from causing wire hooking failure.

[0049] Furthermore, such as Figure 3As shown, the reset structure 405 includes a positioning block 406 and a second push plate 407 disposed on the left and right sides of the rocker arm feed rod 101, and a fifth drive structure 408 connected to the second push plate 407. The positioning block 406 is disposed on the side close to the first push plate 403. The fifth drive structure 408 is used to push the second push plate 407 toward the positioning block 406 to clamp the rocker arm feed rod 101 and drive the rocker arm feed rod 101 to reset.

[0050] The fifth drive structure 408 connects to the bottom and drives the second push plate 407 to clamp onto the positioning block 406, which can accurately clamp the wire feed rod back to the zero position. The clamping reset method avoids excessive pushing reset and ensures high repeatability of the reset position each time. This clamping reset method does not require the addition of slide rails or springs to the base 105, and the structure is compact and occupies little space.

[0051] Furthermore, such as Figure 3 , 5 As shown, the reset structure 405 also includes a second limiting rod 409 disposed on one side of the outlet end 104 of the rocker arm wire feed rod 101. The second limiting rod 409 is disposed on the side close to the first push plate 403.

[0052] Because the rocker arm feed rod 101 is relatively long, when the reset structure 405, located near the inlet end 103, pushes the rocker arm feed rod 101 to reset, the lateral force generated at the outlet end 104 of the rocker arm feed rod 101 is relatively large, which can easily lead to over-reset. When over-reset, it abuts against the second limit rod 409 to form a limit. The two-stage limit shares the impact, avoids single-point reset deformation, and improves reset stability and life. At the same time, the second limit rod 409 can be used as a visual reference to facilitate debugging and maintenance.

[0053] Furthermore, such as Figure 1 , 4 As shown, the first drive structure 102 is located below the rocker arm wire feed rod 101 and is connected to the base 105.

[0054] The first drive structure 102 is located below the rocker arm feed rod 101 and directly connected to the base 105, so that the thrust axis is coplanar with the feed rod movement axis, eliminating additional bending moment, reducing guide rail wear, and utilizing the bottom space to reduce the space occupied by the equipment, further reducing costs.

[0055] Furthermore, such as Figure 2-3 As shown, the clamping block structure 301 includes an L-shaped clamping seat 303 and a clamping block 304 arranged opposite to each other. The third driving structure 302 can drive the clamping block 304 to move towards the L-shaped clamping seat 303 to clamp the wire 5 passing between the two.

[0056] The clamping block structure 301 adopts an L-shaped clamping seat 303 and a clamping block 304 facing each other. The third drive structure 302 is connected from the bottom and directly pushes the clamping block 304 toward the L-shaped clamping seat 303. The L-shaped facade forms a bidirectional positioning, so that the wire 5 is automatically centered and does not deviate at the moment of clamping, reducing the risk of clamping marks and flattening. The L-shaped clamping seat 303 has a very simple structure and small size, which makes it easy to be directly installed on the base 105 and move synchronously with the wire feeding rod.

[0057] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
