Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and in particular to a heat shrink tube heating device and a method for using the same. Background Art

[0002] The wiring harness provides the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc.

[0003] Wiring harnesses are widely used in the automotive field. When producing and processing automotive wiring harnesses, it is often necessary to cut various cables first, then strip the cut ends and crimp metal parts. The shorter cables after processing will finally be laid and combined according to the circuit diagram. The role of the metal parts is to facilitate the combination with the plastic terminals. Therefore, in order to ensure that the metal parts and the cable ends can be sealed, plastic tubes are installed at the crimping points and the plastic tubes are thermoformed at the crimping points by high-temperature heating. Existing thermoplastic equipment generally uses a separate heating device for heating. This heating device generally corresponds to a separate wire feeding assembly. When used, The cable will be fixed on the wire feeding assembly and then sent into the heating device. After a period of time, it will be reset and taken out to realize the thermoplastic operation. The existing wire harness production workshops generally adopt the form of assembly lines, that is, the end of each process is the head of the next process. In this way, the production line will be arranged in an S-shaped distribution in the workshop. Therefore, there is more than one operating station for thermoplastic processing in the same process. After the thermoplasticization is completed, when preparing for the next batch of wire harness thermoplasticization, the heating device is in an idle state. If the heating device is turned off, it will cause subsequent reheating, which wastes energy. If the heating device is not turned off, the heating device will continue to work idle, which is still a waste of energy.

[0004] At the same time, the wire harnesses are often fed into the heating device in batches rather than being thermoformed individually. When the wire harnesses are fixed on the wire feeding assembly, if they are too dense, the operation will be very troublesome, and if they are too scattered, it will cause a waste of space.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0052] In order to facilitate wiring inside the rack 1 , in this embodiment, a plurality of wire racks 26 are installed on the inner side wall of the top of the rack 1 , and a scale 33 is fixedly installed on the side wall of the inner beam 29 away from the assembly frame 31 .

[0053] In order to enable the wire feeding mechanism 3 to stably feed the wire harness 59 into the interior of the box body 12, in this embodiment, the wire feeding mechanism 3 includes a top plate 34, which is arranged along the width direction of the frame 1, and the four corners of the bottom of the top plate 34 are fixedly mounted on the top of the four support rods 27 on one side of the outer cover shell 7. The top plate 34 is provided with strip holes 35 distributed symmetrically along the center, and the strip hole 35 located in the middle of the top plate 34 is arranged along the width direction of the top plate 34, and the two ends of the strip holes 35 on both sides are arranged along the width direction of the top plate 34, and the middle parts of the strip holes 35 on both sides are inclined, and the inclination angle of the middle parts of the strip holes 35 on both sides gradually increases from the inside to the outside. A wire feeding module 36 is also provided on the top of the top plate 34, and the number of the wire feeding modules 36 is the same as that of the top plate 34. The number of strip holes 35 is equal and corresponds one to one. The top of the wire feeding module 36 is coplanar with the notch 11 and the strip opening 14.

[0056] See also Figure 15-18In order to enable the two wire feeding mechanisms 3 on both sides of the box 12 to respectively realize the wire feeding operation of the wire harness 59, in this embodiment, the adjustment mechanism 25 includes a motor 62 and a transmission 63 fixedly mounted on the horizontal plate 24, the transmission 63 is connected to the output shaft of the motor 62, the output shaft end of the transmission 63 is fixedly mounted with a rotating shaft 64, the bottom center of the support plate 22 is fixedly mounted with a bearing seat 65, the top end of the rotating shaft 64 is rotatably connected to the support plate 22 through the bearing seat 65, and the outside of the rotating shaft 64 is fixedly mounted with a rotating plate 66. The rotating plate 66 is arranged coplanar with the guide wheel 45. A fan-shaped plate 67 is symmetrically arranged on the outer side of the rotating plate 66. The fan-shaped plate 67 and the rotating plate 66 are coaxial and integrally arranged. An arc plate 68 is coaxially provided on the outer side of the outer wall of the fan-shaped plate 67. An extension strip 69 is integrally provided at both ends of the arc plate 68. The end of the extension strip 69 away from the arc plate 68 is arranged away from the rotating plate 66. A connecting strip 70 is fixedly installed on the side of the bottom of the arc plate 68 away from the fan plate 67. The end of the connecting strip 70 away from the arc plate 68 is fixedly connected to the outer side of the arc plate 68.

[0057] When the motor 62 is started, the motor 62 will drive the rotating shaft 64 to rotate through the transmission 63, and the rotating shaft 64 will drive the rotating plate 66 to rotate synchronously. When the rotating plate 66 rotates, it will drive the fan-shaped plate 67 to rotate. The fan-shaped plate 67 will then drive the arc plate 68 to rotate synchronously through the connecting bar 70. When the arc plate 68 rotates around the rotating shaft 64, when the outermost end of the extended strip 69 on one side of the rotating shaft 64 rotates in the direction of rotation and contacts the guide wheel 45 on one side, it can drive the guide wheel 45 to move closer to the rotating shaft 64 until the guide wheel 45 moves between the arc plate 68 and the fan plate 67. At this time, the rotating shaft 64 continues to rotate and will no longer drive The guide wheel 45 moves, and at this time the plastic tube 61 at the end of the wire harness 59 will be completely moved into the box body 12. The time when the guide wheel 45 is between the arc plate 68 and the fan plate 67 is the time for the plastic tube 61 to be thermoplasticized. The rotating plate 66 continues to rotate. When the guide wheel 45 moves out from between the arc plate 68 and the fan plate 67, due to the action of the tension spring 48, the guide wheel 45 will be reset along the extended strip 69 on the other side until the extended strip 69 on one side of the rotation direction of the rotating shaft 64 contacts the guide wheel 45 at the bottom of the other wire feeding mechanism 3, so that the plastic tube 61 at the end of the wire harness 59 at the other end of the top of the frame 1 can be thermoplasticized.

A fixing groove 72 is opened on the side of the bottom of the fan-shaped plate 67 away from the rotating plate 66 , and one end of the connecting bar 70 is fixedly installed in the fixing groove 72 .

[0059] Through the above-mentioned scheme of the present invention, the strip hole 35 provided in the present invention can adjust the wire feeding module 36. When the wire feeding module 36 moves toward the box body 12, the plastic tube 61 at the end of the wire feeding module 36 can be gathered and sent into the box body 12 for thermoplasticization. When the wire feeding module 36 is reset, the wire harnesses 59 will be separated from each other. At this time, the effect of the heat dissipation fan 32 can be used to achieve rapid heat dissipation, ensuring that the plastic tube 61 after thermoplasticization can be quickly shaped. Moreover, the movement and adjustment of the wire feeding module 36 is achieved by rotating the fan plate 67 and the arc plate 68. When the wire feeding mechanism 3 on one side feeds the plastic tube 61 and the metal part 60 into the box body 12, the wire feeding mechanism 3 on the other side can place and assemble the wire harness 59. The same heating mechanism 2 can cooperate with the two wire feeding mechanisms 3 to perform thermoplastic operations on the plastic tube 61 at the end of the wire harness 59 without stopping, thereby greatly improving the thermoplastic efficiency.

When the wire feeding module 36 moves toward the box body 12, the plastic tube 61 at the end of the wire feeding module 36 can be gathered and sent into the box body 12 for thermoplasticization. When the wire feeding module 36 is reset, the wire harnesses 59 will be separated from each other. At this time, the cooling fan 32 can be used to quickly dissipate heat, ensuring that the plastic tube 61 after thermoplasticization can be quickly shaped. Moreover, the movement and adjustment of the wire feeding module 36 is achieved by rotating the fan plate 67 and the arc plate 68. When the wire feeding mechanism 3 on one side feeds the plastic tube 61 and the metal part 60 into the box body 12, the wire feeding mechanism 3 on the other side can place and assemble the wire harness 59. The same heating mechanism 2 can cooperate with the two wire feeding mechanisms 3 to perform thermoplastic operations on the plastic tube 61 at the end of the wire harness 59 without stopping, thereby greatly improving the thermoplastic efficiency.
