Technical Field

[0001] The invention belongs to the technical field of wire material processing, and in particular relates to an automatic tape wrapping device for wrapping wire materials with tape. Background Art

[0002] At present, during the assembly process of wires, it is usually necessary to wrap insulating tape around the terminals of the wires or the connection between two wires to enhance the insulation. At present, the process of wrapping insulating tape is mostly done manually, which greatly reduces production efficiency and increases labor costs. It is also easily disturbed by the instability caused by manual work, resulting in uneven wire quality and poor consistency. Summary of the invention

[0003] The present invention aims to overcome the deficiencies in the above-mentioned prior art and solves the technical problem of providing an automatic tape wrapping device which is highly efficient and can ensure the quality and consistency of the product after tape wrapping.

[0004] In order to solve the technical problems existing in the above-mentioned prior art, an embodiment of the present invention provides an automatic tape winding device, comprising a linear motion mechanism, a frame arranged on the linear motion mechanism, a rotating mechanism rotatably mounted on the frame, and a tape reel eccentrically arranged on the rotating mechanism;

[0005] The rotating mechanism is provided with an avoidance structure which radially extends to the rotation center and is used for the entry of the product to be wrapped with tape; the frame is provided with a swing clamping mechanism which is used for clamping and pulling the tape.

[0006] Furthermore, a self-resetting cutting mechanism is arranged on the rotating mechanism on the side of the avoidance structure; and a horizontal driving mechanism for driving the self-resetting cutting mechanism to cut the adhesive tape is arranged on the frame.

[0007] Furthermore, a tape limiting structure is arranged on the rotating mechanism above the avoidance structure; the tape limiting structure comprises a main body, and a limiting opening is arranged at one end of the main body facing the self-resetting cutting mechanism for the tape to pass through.

[0008] Furthermore, the swing clamping mechanism includes a swing arm rotatably mounted on the frame, a tape clamping structure arranged on the swing arm, and a rotating structure arranged on the frame for driving the swing arm to rotate.

[0009] Furthermore, the self-resetting cutting mechanism includes a cutter seat fixed on the rotating mechanism, and a cutter structure horizontally slidably installed in the cutter seat, and one end of the cutter structure extending out of the cutter seat is sleeved with a first elastic member, one end of the first elastic member abuts against the cutter seat, and the other end abuts against the limiting portion of the cutter structure.

[0010] Furthermore, the rotating mechanism includes a rotating gear rotatably mounted on the frame and a power module for driving the rotating gear to rotate.

[0011] Furthermore, the rotating gear comprises a disc-shaped body; a boss is arranged around the periphery of the disc-shaped body, and meshing teeth are arranged on the boss; and a plurality of rolling elements are arranged on the disc surface of the disc-shaped body at intervals in the circumferential direction.

[0012] Furthermore, the frame includes a frame body, a rear cover and a front cover; an annular limiting groove for matching with the boss is formed between the frame body and the front cover; the rear cover is provided with an annular groove concentric with the disc-shaped body, and the rolling element is rollingly arranged in the annular groove.

[0013] Furthermore, a connecting plate is provided on the rotating mechanism, a mounting seat for mounting the tape reel is provided on the connecting plate, an inner support tensioning structure for abutting against the inner wall surface of the tape reel is radially slidably installed on the mounting seat, and a tensioning driving structure for driving the inner support tensioning structure to slide is provided on the frame.

[0014] Furthermore, the automatic tape wrapping device further comprises a floating buffer limit assembly for axially limiting the tape reel; the floating buffer limit assembly comprises a limit baffle, a threaded connector inserted through the limit baffle, and a second elastic member sleeved between the limit baffle and the head of the threaded connector;

[0015] The threaded connector is used for threaded connection with the mounting seat, and the tape reel is located between the limit baffle and the connecting plate.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0017] The automatic tape winding device of the present invention comprises a linear motion mechanism, a frame arranged on the linear motion mechanism, a rotating mechanism rotatably mounted on the frame, and a tape reel eccentrically arranged on the rotating mechanism; the rotating mechanism is provided with an avoidance structure radially extending to the rotation center, and the frame is provided with a swing clamping mechanism, which is used to clamp and pull the tape.

[0018] The swing clamping mechanism has clamped and tightened the tape and pulled it out to a certain length. The wire enters the rotation center through the avoidance structure and its processing position is bonded with the clamped tape. The rotating mechanism drives the tape reel to rotate counterclockwise. When it rotates to a position close to the set angle (at this time, a certain amount of tape a has been wound around the processing position, and even if the tape a is not clamped and tightened, it will not affect the continued winding of the tape a), in order to avoid interference with the rotating mechanism and the tape reel, the swing clamping mechanism sends the tape away and swings back to its original position; while the rotating mechanism drives the tape reel to rotate, the linear motion mechanism acts in coordination along the axial direction of the wire (consistent with the principle of manual tape wrapping).

[0019] In summary, the present invention can realize mechanized tape wrapping, which not only improves production efficiency and reduces labor costs, but also ensures the quality and consistency of the product after tape wrapping. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A connecting plate 33 is provided on the rotating gear 31, and a mounting seat 34 for mounting the tape reel 4 is provided on the connecting plate 33. An inner support tensioning structure 35 for contacting the inner wall surface of the tape reel 4 is radially slidably installed on the mounting seat 34.

Among them, a T-shaped notch 341 is provided on the mounting seat 34. The inner support tensioning structure 35 includes a body slidably installed in the T-shaped notch 341, a bevel groove structure is provided at the bottom of the body, and a third elastic member is provided between the body and the inner wall of the T-shaped notch 341, and the third elastic member is used to provide an elastic force that makes the body have a tendency to move toward the center of the mounting seat 34. The tensioning driving structure 26 includes a horizontal driving member 261 and a push rod 262 provided on the horizontal driving member 261, and the conical push end of the push rod 262 can pass through the connecting plate 33 and cooperate with the bevel groove structure.

[0035] The self-resetting cutting mechanism 5 includes a cutter seat 51 fixed on the rotating gear 31, and a cutter structure 52 horizontally slidably installed in the cutter seat 51. One end of the cutter structure 52 extending out of the cutter seat 51 is sleeved with a first elastic member 53, one end of the first elastic member 53 abuts against the cutter seat 51, and the other end abuts against the limiting portion of the cutter structure 52; the first elastic member 53 is used to provide an elastic force that causes the cutter structure 52 to have a tendency to move in a direction away from the tape a.

[0036] The swing clamping mechanism 7 includes a swing arm 71 rotatably mounted on the frame 21 , a tape clamping structure 72 disposed on the swing arm 71 , and a rotating structure 73 (preferably a rotating motor) disposed on the frame 21 for driving the swing arm 71 to rotate.

[0037] In order to ensure that the adhesive tape a is wrapped around the product in a limited manner, the above structure is optimized in this embodiment.

[0038] A tape limiting structure 8 is provided on the rotating mechanism 3 above the avoidance structure 312 ; the tape limiting structure 8 comprises a main body 81 , and a limiting opening 82 for the tape a to pass through is provided at one end of the main body 81 facing the self-resetting cutting mechanism 5 .

[0039] The automatic tape winding device b also includes a floating buffer limit assembly 9 for axially limiting the tape reel 4; the floating buffer limit assembly 9 includes a limit baffle 91, a threaded connector 92 passed through the limit baffle 91, and a second elastic member 93 sleeved between the limit baffle 91 and the head of the threaded connector 92; the threaded connector 92 is used for threaded connection with the mounting seat 34, and the tape reel 4 is located between the limit baffle 91 and the connecting plate 33.

[0040] The following is a brief description of the working process of the automatic tape wrapping device b using wire tape wrapping as an example:

[0041] Depend on Figures 1 to 8 As shown together, the lateral transfer device 101 clamps and drives the wire to move, so that the position to be processed of the wire enters the rotation center from the left side through the avoidance structure 312; at the same time, the rotating structure 73 in the swing clamping mechanism 7 drives the swing arm 71 to rotate clockwise to the position, and the tape clamping structure 72 clamps the tape a, and then the rotating structure 73 drives the swing arm 71 to rotate counterclockwise to a certain angle, and the clamped and tightened tape a is pulled out to a certain length (after cutting, the tape a is too short and is located at the rotation center, and the swing clamping mechanism 7 needs to be clamped and tightened and pulled out to a certain length to facilitate the subsequent winding of the tape a on the wire). After the wire moves into place, its position to be processed is bonded to the clamped and tightened tape a.

[0042] The power module 32 drives the rotating gear 31 to carry the tape reel 4 to rotate counterclockwise by a certain angle (further rotation will collide and interfere with the swing clamping mechanism 7, and at this time, a certain amount of tape a has been wound around the position to be processed, and even if the tape a is not clamped and tightened, it will not affect the continued winding of the tape a). In order to avoid the rotating gear 31 and the tape reel 4 that continue to rotate, the tape clamping structure 72 in the swing clamping mechanism 7 releases the tape a, and then the rotating structure 73 drives the swing arm 71 to swing counterclockwise to reset. The power module 32 drives the rotating gear 31 to rotate counterclockwise while the linear motion mechanism 1 acts in coordination (consistent with the principle of manual tape winding).

[0043] After the tape a is wound, the rotating gear 31 stops rotating, and the tensioning driving structure 26 drives the inner support tensioning structure 35 to slide until it is in close contact with the inner wall surface of the tape reel 4; then the horizontal driving mechanism 6 drives the cutting part of the cutting structure 52 in the self-resetting cutting mechanism 5 to extend the cutting seat 51 to cut the tape a.

[0044] The linear motion mechanism 1 drives the frame 2 to retreat and reset, avoiding the movement of the wire.

[0045] In summary, the present invention can realize mechanized tape wrapping, which not only improves production efficiency and reduces labor costs, but also ensures the quality and consistency of the product after tape wrapping.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
