Description

Technical Field

[0002] A wire harness is an integrated component in an electrical system, consisting of multiple wires, connectors, terminals, and insulation materials combined according to specific functions. It is widely used in automotive, electronic equipment, aerospace, and industrial machinery industries. Its core function is to connect disparate electrical components (such as sensors, controllers, and actuators) into an ordered circuit network via wires, enabling signal transmission or power supply. To slow down the aging and corrosion of wire harnesses due to long-term use, extend their overall lifespan, and reduce the frequency of equipment maintenance and wire harness replacement, heat shrink tubing is typically used to cover the wire harness.

[0003] Currently, the application of heat shrink tubing to wire harnesses is mainly accomplished using heat shrink equipment. However, in existing heat shrink equipment, during the heat shrinking process, when the diameters on both sides of the wire harness are inconsistent, the belt cannot automatically adjust the pressure according to the diameter difference, resulting in an inability to stably clamp the wire harness and affecting the heat shrinking effect.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figure 1As shown, a transmission mechanism for a wire harness heat shrink tubing baking machine includes a front belt drive module 1, a rear belt drive module 2, and an elastic clamping module 3. The rear belt drive module 2 is disposed opposite to the front belt drive module 1, and a transmission range is formed between their opposing surfaces to clamp and transmit the wire harness on both sides. The elastic clamping module 3 is disposed on the side of the rear belt drive module 2 and acts within the transmission range. The clamping force on both sides of the wire harness can be adjusted through the elastic clamping module 3.

[0030] Further, see Figure 2 As shown, the front belt drive module 1 includes a first front clamping synchronous pulley assembly 11, a second front clamping synchronous pulley assembly 12, and a drive motor 13. The first front clamping synchronous pulley assembly 11 and the second front clamping synchronous pulley assembly 12 are connected together via two sets of front connecting shafts 14, while the second front clamping synchronous pulley assembly 12 is connected to a front connecting rod 15. The output shaft of the drive motor 13 is connected to the front connecting rod 15 via a transmission element 16. During transmission, the drive motor 13 drives the front connecting rod 15 to rotate via the transmission element 16, and the rotating front connecting rod 15 drives... The second front clamping synchronous pulley assembly 12 rotates, and the rotating second front clamping synchronous pulley assembly 12 drives the first front clamping synchronous pulley assembly 11 to rotate synchronously with it through the front connecting shaft 14; wherein, in this embodiment, the drive motor 13 is a servo motor, and the transmission element 16 is a synchronous pulley assembly, but it is not limited to a synchronous pulley assembly, and other types can also be used, such as gear transmission, etc.; in addition, it should be noted that the number of sets of the front connecting rod 15 is only one implementation and is not intended to limit the scope of this application. In actual settings, the specific number of sets is sufficient to meet the requirements.

[0031] For further details, please refer to [link / reference]. Figure 2 As shown, two sets of idler pulleys 17 are provided on the outer side of the synchronous belt to which the second front clamping synchronous pulley assembly 12 belongs.

[0032] Further, see Figure 3As shown, the rear belt drive module 2 includes a pair of rear clamping synchronous pulley assemblies 21 and a drive motor 13; the pair of rear clamping synchronous pulley assemblies 21 are connected together by two sets of rear connecting shafts 22, and one set of rear clamping synchronous pulley assemblies 21 is connected to a rear connecting rod 23; the output shaft of the drive motor 13 is connected to the rear connecting rod 23 through a transmission element 16; during transmission, the drive motor 13 drives the rear connecting rod 23 to rotate through the transmission element 16, and the rotating rear connecting rod 23 drives the rear clamping synchronous pulley assembly connected to it. The rotating component 21 drives another set of rear clamping synchronous pulley assemblies 21 to rotate synchronously via the rear connecting shaft 22. In this embodiment, the drive motor 13 is also a servo motor, and the transmission element 16 is also a synchronous pulley assembly, but it is not limited to synchronous pulley assemblies; other types, such as gear transmission, can also be used. Furthermore, it should be noted that the number of sets of the rear connecting shaft 22 is only one implementation and is not intended to limit the scope of this application. In actual settings, the specific number of sets should meet the requirements.

[0033] It should be noted that after the rear belt drive module 2 is installed with the front belt drive module 1, see [link to relevant documentation]. Figure 1 and 7 As shown (A in the figure represents the mounting frame), the two are positioned opposite each other. In this embodiment, the first front clamping synchronous pulley assembly 11 is positioned opposite to a set of rear clamping synchronous pulley assemblies 21, while the second front clamping synchronous pulley assembly 12 is positioned opposite to another set of rear clamping synchronous pulley assemblies 21. At this time, a section is formed between the first front clamping synchronous pulley assembly 11 and the set of rear clamping synchronous pulley assemblies 21, and between the second front clamping synchronous pulley assembly 12 and the other set of rear clamping synchronous pulley assemblies 21, respectively, for clamping one side of the wire harness. The transmission range of the transmission: During transmission, one side of the wire harness is clamped in the transmission range between the first front clamping synchronous pulley assembly 11 and a set of rear clamping synchronous pulley assemblies 21, while the other side of the wire harness is clamped in the transmission range between the second front clamping synchronous pulley assembly 12 and another set of rear clamping synchronous pulley assemblies 21. With the start of the drive motor 13, the synchronous belts belonging to the first front clamping synchronous pulley assembly 11, the second front clamping synchronous pulley assembly 12, and a pair of rear clamping synchronous pulley assemblies 21 begin to rotate, thereby realizing the transmission of the wire harness.

[0034] Further, see Figure 1 and Figure 7As shown (A in the figure represents the mounting frame), an elastic clamping module 3 is respectively provided on the inner side of the synchronous belt of each pair of rear clamping synchronous belt pulley assemblies 21, and the elastic clamping modules 3 all act within the transmission range; see also Figure 4-5 As shown, the elastic clamping module 3 includes a fixing block 31. The front end face of the fixing block 31 has 11 sets of connecting holes 32 evenly distributed from top to bottom. The number of sets can be set according to the specific requirements, but not limited to 11 sets. A connecting rod 33 that can slide inside each connecting hole 32 is inserted into it. A spring 34 is provided between the rear end of the connecting rod 33 and the inner bottom surface of the connecting hole 32. A clamping wheel 35 is provided at the front end of the connecting rod 33. When the elastic clamping module 3 is connected to a pair of rear clamping synchronous pulley assemblies 21, the spring 34 tends to drive the connecting rod 33 to move outward from the connecting hole 32 (i.e., the front end face of the fixing block 31) without the action of external force, thereby keeping the clamping wheel 35 at the front end of the connecting rod 33 abutting against the inner surface of the synchronous belt of the rear clamping synchronous pulley assembly 21. During transmission, the synchronous belt of the rear clamping synchronous pulley assembly 21 is subjected to force and squeezes the pressure wheel 35, causing the connecting rod 33 to move inward toward the connecting hole 32. This allows the pressure to be automatically adjusted according to the outer diameter of both sides of the wire harness during the transmission process, ensuring stable clamping of the wire harness.

[0035] In this embodiment, see Figure 4 As shown, a removable cover plate 36 is provided on the fixing block 31. When the cover plate 36 is removed, the mating surface between the fixing block 31 and the cover plate 36 communicates with the connecting hole 32; and see... Figure 6 As shown, a countersunk hole 331 is formed at the rear end of the connecting rod 33 for the spring 34 to sink into it; and see further... Figure 6 As shown, semi-circular slots 321 are respectively opened between the upper and lower end faces of the connecting rod 33 and the mating surfaces of the connecting hole 32. A ball bearing 37 is provided in the slot 321, and the rolling engagement between the connecting rod 33 and the connecting hole 32 is achieved by the ball bearing 37. The slot 321 opened on the connecting hole 32 passes through the front end face of the fixing block 31, while the slot 321 opened on the connecting rod 33 does not pass through its two end faces.
