Description

Technical Field

[0001] This invention belongs to the field of wire binding machine technology, and particularly relates to a reciprocating unidirectional winding mechanism. Background Technology

[0002] A winding mechanism is a mechanism that winds a thread-like object onto a specific workpiece. Existing winding mechanisms have the problem of uneven winding when the workpiece is finished.

[0003] Chinese patent CN218809634U discloses a multifunctional winding mechanism. In use, a winding block is placed on the surface of a rotating shaft, and then the position of the winding block is fixed by a fixing component to facilitate winding. A drive motor drives the drive block to rotate inside a support plate, and the rotating shaft rotates along with the drive block, causing the winding block to rotate and perform the winding work on copper wire. However, this type of winding mechanism has a fixed main body, resulting in very uneven concentration of the wire bundle during winding. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a reciprocating unidirectional winding mechanism for binding and tightening wire harnesses and for automatic tightening and cutting, and to provide a transmission method for realizing multiple repeated binding.

[0005] To achieve the above objectives, the specific technical solution of the reciprocating unidirectional winding mechanism of the present invention is as follows:

[0006] A reciprocating unidirectional winding mechanism includes a winding mechanism, a clutch assembly and a wire harness folding mechanism on one side of the winding mechanism, a gear transmission mechanism on the other side, and a pin assembly between the winding mechanism and the gear transmission mechanism.

[0007] Both the winding mechanism and the wire harness folding mechanism are slidably mounted on the slide rail assembly;

[0008] One end of the ejector pin assembly passes through the winding mechanism and is slidably disposed in the winding mechanism, so that the winding mechanism can follow the gear transmission mechanism to perform reciprocating linear motion; when the clutch assembly abuts against the ejector pin assembly, the other end of the ejector pin assembly will engage with the gear transmission mechanism. After engagement, the gear transmission mechanism will drive the winding mechanism to perform winding motion while performing linear motion.

[0009] A wire-spinning mechanism is fixedly installed on the side of the winding mechanism facing the wire harness folding mechanism;

[0010] Both the gear transmission mechanism and the wire harness folding mechanism are electrically connected to the control system;

[0011] In the initial state, the clutch assembly and the ejector assembly are separated. The wire harness passes through the winding mechanism and the wire harness folding mechanism in sequence. After being folded by the wire harness folding mechanism, it enters the wire throwing mechanism and is held in place by the wire throwing mechanism. During winding, the control system drives the wire harness folding mechanism away from the winding mechanism. At the same time, the gear transmission mechanism moves towards the clutch assembly until the clutch assembly and the ejector assembly are in close contact. This allows the gear transmission mechanism to push the winding mechanism forward at a constant speed while the winding process of the wire harness is carried out.

[0012] Furthermore, the ejector assembly includes a clutch ejector pin slidably disposed in the winding mechanism. The end of the clutch ejector pin facing the clutch assembly is provided with an abutment block that cooperates with the clutch assembly. The end of the clutch ejector pin facing the gear transmission mechanism is provided with a snap-fit ​​block that snaps into the gear transmission mechanism. The end of the snap-fit ​​block facing the gear transmission mechanism is integrally formed with a lug that matches the gear transmission mechanism. A control rod is fixedly disposed on the snap-fit ​​block. The control rod is slidably disposed on a guide block. The guide block is fixed between the gear transmission mechanism and the winding mechanism. The control rod is in contact with the ejector pin.

[0013] A clutch spring is installed on the snap-fit ​​block. One end of the clutch spring abuts against the snap-fit ​​block, and the other end abuts against the gear transmission mechanism.

[0014] Furthermore, the wire-spinning mechanism includes a wire-spinning body fixed to one side of the winding mechanism. A wire-clamping wrench is rotatably mounted on the wire-spinning body. A wire channel is opened inside the wire-spinning body. One end of the wire-clamping wrench is set in the wire channel, and the other end is set with a clamping spring. One end of the clamping spring abuts against the wire-clamping wrench, and the other end abuts against the wire-spinning body.

[0015] When the wire harness enters the cable channel, the cable clamp wrench, under the action of the spring, firmly clamps the wire harness into the cable channel.

[0016] Furthermore, the gear transmission mechanism includes a lead screw, on which a third transmission gear is threadedly connected. One side of the third transmission gear meshes with a first transmission gear, and the first transmission gear also meshes with a second transmission gear and a motor.

[0017] Furthermore, the winding mechanism includes a one-way bearing that is slidably connected to the ejector pin assembly. The one-way bearing is fixed inside the belt drive pulley. Multiple belt driven pulleys are arranged around the belt drive pulley. The same synchronous belt is fitted on the multiple belt driven pulleys. One side of the synchronous belt meshes with the belt drive pulley, and the other side meshes with the winding gear.

[0018] The winding gear has a first channel for the wire harness and a workpiece placement hole.

[0019] Furthermore, the wire harness folding mechanism includes a wire guide block slidably disposed on the slide rail assembly, a wire harness path insert is disposed inside the wire guide block, a second wire harness channel is formed between the wire harness path insert and the wire guide block, and the outlet of the second wire harness channel corresponds to the inlet of the wire-spinning mechanism.

[0020] The reciprocating unidirectional winding mechanism of the present invention has the following advantages: the winding mechanism can move forward at a constant speed while rotating and winding, and can efficiently and evenly wind the wire harness onto the workpiece; after one winding is completed, the mechanism automatically resets and prepares for the next winding process, saving manpower and improving work efficiency.

[0043] To better understand the purpose, structure, and function of this invention, a reciprocating unidirectional winding mechanism of this invention will be described in further detail below with reference to the accompanying drawings.

[0044] A reciprocating unidirectional winding mechanism includes a winding mechanism 20, a clutch assembly 50 and a wire harness folding mechanism 60 are provided on one side of the winding mechanism 20, a gear transmission mechanism 10 is provided on the other side, and a pin assembly 70 is provided between the winding mechanism 20 and the gear transmission mechanism 10.

[0045] Both the winding mechanism 20 and the wire harness folding mechanism 60 are slidably mounted on the slide rail assembly 40;

[0046] One end of the ejector pin assembly 70 passes through the winding mechanism 20 and is slidably disposed in the winding mechanism 20, so that the winding mechanism 20 can follow the gear transmission mechanism 10 to perform reciprocating linear motion; when the clutch assembly 50 abuts against the ejector pin assembly 70, the other end of the ejector pin assembly 70 will engage with the gear transmission mechanism 10. After engagement, the gear transmission mechanism 10 will drive the winding mechanism 20 to perform winding motion while performing linear motion.

[0047] A wire-spinning mechanism 30 is fixedly installed on the side of the winding mechanism 20 facing the wire harness folding mechanism 60;

[0048] Both the gear transmission mechanism 10 and the wire harness folding mechanism 60 are electrically connected to the control system;

[0049] Initially, the clutch assembly 50 is separated from the ejector assembly 70. The wire harness 00 passes through the winding mechanism 20 and the wire harness folding mechanism 60 in sequence. After being folded by the wire harness folding mechanism 60, it enters the wire-spinning mechanism 30, where the wire harness 00 is held in place. During winding, the control system drives the wire harness folding mechanism 60 away from the winding mechanism 20. At the same time, the gear transmission mechanism 10 moves towards the clutch assembly 50 until the clutch assembly 50 is in close contact with the ejector assembly 70. This allows the gear transmission mechanism 10 to push the winding mechanism 20 forward at a constant speed while simultaneously winding the wire harness 00. Specifically, the power of the motor 105 is decomposed into the transmission of the third transmission gear 104 along the lead screw 101 and the winding motion of the winding mechanism 20.

[0050] In this embodiment, the ejector pin assembly 70 includes a clutch ejector pin 701 slidably disposed in the winding mechanism 20. The clutch ejector pin 701 has an abutment block 702 that cooperates with the clutch assembly 50 at one end facing the clutch assembly 50. The clutch ejector pin 701 has a snap-fit ​​block 703 that snaps into the gear transmission mechanism 10 at one end facing the gear transmission mechanism 10. The snap-fit ​​block 703 has an integrally formed lug 705 that matches the gear transmission mechanism 10 at one end facing the gear transmission mechanism 10. A control rod 706 is fixedly disposed on the snap-fit ​​block 703. The control rod 706 is slidably disposed on the guide block 707. The guide block 707 is fixed between the gear transmission mechanism 10 and the winding mechanism 20. The control rod 706 is in contact with the ejector pin 701.

[0051] A clutch spring 704 is provided on the snap-fit ​​block 703. One end of the clutch spring 704 abuts against the snap-fit ​​block 703, and the other end abuts against the gear transmission mechanism 10.

[0052] In this embodiment, the wire-spinning mechanism 30 includes a wire-spinning body 304 fixed to one side of the winding mechanism 20. A wire-clamping wrench 302 is rotatably disposed on the wire-spinning body 304. A wire channel 301 is opened inside the wire-spinning body 304. One end of the wire-clamping wrench 302 is disposed in the wire channel 301, and the other end is disposed with a clamping spring 303. One end of the clamping spring 303 abuts against the wire-clamping wrench 302, and the other end abuts against the wire-spinning body 304.

[0053] When wire harness 00 enters wire channel 301, wire clamp wrench 302, under the action of spring, tightly clamps wire harness 00 in wire channel 301 to prevent wire harness 00 from falling off during the winding process;

[0054] The wire-spinning mechanism 30 is fixedly connected to the winding gear 206. When the winding gear 206 rotates, the wire-spinning mechanism 30 makes a circular motion around the workpiece, winding the wire harness 00 onto the workpiece. At this time, the third transmission gear 104 continues to drive along the lead screw 101, pushing the winding mechanism 20 forward at a constant speed. Thus, the winding mechanism 20 uniformly winds the wire harness 00 onto the workpiece.

[0055] In this embodiment, the gear transmission mechanism 10 includes a lead screw 101, on which a third transmission gear 104 is threadedly connected. One side of the third transmission gear 104 meshes with a first transmission gear 102. The first transmission gear 102 also meshes with a second transmission gear 103 and a motor 105.

[0056] When the winding begins, the motor 105 rotates in the forward direction. The gear driven by the motor 105 will drive the first transmission gear 102 to rotate. The first transmission gear 102 meshes with the second transmission gear 103 and the third transmission gear 104.

[0057] In this embodiment, the winding mechanism 20 includes a one-way bearing 203 that is slidably connected to the ejector pin assembly 70. The one-way bearing 203 is fixed inside the belt drive wheel 204. A plurality of belt driven wheels 205 are arranged around the belt drive wheel 204. The same synchronous belt 201 is sleeved on the plurality of belt driven wheels 205. One side of the synchronous belt 201 meshes with the belt drive wheel 204, and the other side meshes with the winding gear 206.

[0058] The winding gear 206 has a wire harness first channel 202 and a workpiece placement hole 207.

[0059] As the winding mechanism 20 slides along the linear guide rail, the pin assembly 70 in the winding mechanism 20 collides with the clutch assembly 50, the motor 105 works, and the second transmission gear 103 is connected to the belt drive wheel 204, and the belt drive wheel 204 starts to work.

[0060] Driven by the belt drive pulley 204, power is transmitted to the belt driven pulley 205 and the wound gear 206 via the synchronous belt 201.

[0061] Most existing winding mechanisms 20 require manual resetting for secondary winding, which significantly increases labor costs in situations requiring repeated winding, resulting in obvious drawbacks. For example, Chinese patent CN218809634U describes a multi-functional winding mechanism 20 that requires manual resetting after winding, further increasing labor costs.

[0062] In this invention, at the end of winding, the control motor 105 rotates in a certain direction. At this time, due to the presence of the one-way bearing 203, the large winding tooth will not rotate, and the third transmission gear 104 will push the winding mechanism 20 to the starting position through reverse transmission along the lead screw 101, thereby resetting and preparing for secondary winding.

[0063] In this embodiment, the wire harness folding mechanism 60 includes a wire guide block 601 slidably disposed on the slide rail assembly 40. A wire harness path insert 602 is disposed inside the wire guide block 601. A second wire harness channel 603 is formed between the wire guide block 602 and the wire guide block 601. The outlet of the second wire harness channel 603 corresponds to the inlet of the wire-spinning mechanism 30.

[0064] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
