[0003] In the existing production line of automotive wire harnesses, different processes require workers to carry out production at different workstations. During assembly, it leads to long-term handling of raw materials and semi-finished products, increasing the production cycle. Moreover, fixed processes have relatively high technical requirements for workers. Workers moving between multiple processes increase fatigue and the possibility of human errors.

[0004] In view of this, in order to overcome the above technical problems, the utility model proposes a wire harness assembly production line to solve the above technical problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, the utility model proposes a wire harness assembly production line. Through the setting of the turntable and the conveyor belt, the driving motor drives the conveyor belt to rotate through the turntable, so that the conveyor belt drives the workbench frame connected to it to move synchronously, enabling the workbench frame to surround between the upper frame and the lower frame. Thus, workers only need to carry out specific assembly or processing tasks on the moving workbench frame, without the need for workers to move between multiple processes, reducing the working intensity and operation steps of workers, thereby reducing the fatigue of workers and the occurrence of human errors, and improving production efficiency.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figures 1 to 4 shown, a wire harness assembly production line according to the present utility model includes:

[0024] Frame 1, the frame 1 includes an upper frame 11 and a lower frame 12; the lower end of the lower frame 12 is fixedly connected with feet; the upper frame 11 is located above the lower frame 12; a support column 13 is arranged between the upper frame 11 and the lower frame 12; the support column 13 is fixedly connected with the upper frame 11 and the lower frame 12;

[0025] Workbench 14, the workbench 14 is located between the upper frame 11 and the lower frame 12; pinch rollers 141 are rotatably connected to the upper end and the lower end of the workbench 14; the workbench 14 is in rotational contact with the upper frame 11 and the lower frame 12 through the pinch rollers 141; mounting columns 15 are arranged on both sides of the support column 13; the mounting columns 15 are fixedly connected with the lower frame 12; a turntable 16 is arranged above the mounting columns 15; there are two mounting columns 15; a drive motor 151 is fixedly connected to the upper end of one of the mounting columns 15; the drive motor 151 is used to drive the turntable 16 to rotate; the two turntables 16 are connected by a transmission belt 152 for belt drive connection; the workbench 14 is rotatably connected to the lower end of the transmission belt 152 through a connecting rod 165.

[0026] In this embodiment, teeth 161 are mounted on the surface of the turntable 16; tooth grooves 153 are formed in the inner wall of the transmission belt 152; the turntable 16 is in meshing transmission with the tooth grooves 153 in the inner wall of the transmission belt 152 through the teeth 161 on its surface.

[0027] In this embodiment, a groove 162 is formed in the outer wall of the turntable 16; the tooth 161 is slidably and sealingly connected in the groove 162; an electromagnetic sheet 163 is embedded in the bottom of the groove 162; a connecting spring 164 is arranged inside the groove 162; one end of the connecting spring 164 is fixedly connected to the tooth 161, and the other end is fixedly connected to the bottom of the groove 162.

[0028] During operation, in the production line of existing automotive wire harnesses, the generally adopted methods are fixed processes or batch production. In both of these methods, workers carry out production at fixed workstations, which leads to long-time handling of raw materials and semi-finished products, increases the production cycle, and the fixed processes have relatively high technical requirements for workers. Workers move between multiple processes, increasing fatigue and the possibility of human errors.

[0029] In response to this, through the setting of the turntable 16 and the transmission belt 152 in this utility model, the driving motor 151 drives the transmission belt 152 to rotate through the turntable 16, and the transmission belt 152 drives the workbench 14 rotatably connected thereto to move synchronously, so that the workbench 14 can surround between the upper frame 11 and the lower frame 12. Thus, workers only need to carry out specific assembly or processing tasks on the moving workbench 14, without the need for workers to move between multiple processes, reducing the working intensity and operation steps of workers, thereby reducing the fatigue of workers and the occurrence of human errors, and improving production efficiency.

[0030] In the initial state, the conveyor belt 152 is installed at the lower end of the upper frame 11, and the electromagnetic sheet 163 is in a power-off state. At this time, the tooth 161 extends out of the groove 162 under the push of the connecting spring 164, so that the tooth 161 extending out of the groove 162 can be inserted into the tooth groove 153 on the inner wall of the conveyor belt 152. When in use, the staff needs to install the new energy vehicle wire harness on the workbench 14, and then control the driving motor 151 to operate, so that the driving motor 151 can drive the turntable 16 to rotate, and the turntable 16 drives the tooth 161 in the groove 162 to rotate synchronously, so that the tooth 161 located in the tooth groove 153 can push the inner wall of the tooth groove 153 to push the conveyor belt 152 to slide in a circumferential manner at the lower end of the upper frame 11. Since the workbench 14 is rotationally connected to the conveyor belt 152 through the connecting rod 165, the conveyor belt 152 can drive the workbench 14 to move synchronously through the connecting rod 165 rotationally connected to it. And because the workbench 14 is in rotational contact with the upper frame 11 and the lower frame 12 through the pinch roller 141, when the conveyor belt 152 pushes the workbench 14 to move, the workbench 14 is limited between the upper frame 11 and the lower frame 12 through the pinch roller 141, so that the workbench 14 rolls around the upper frame 11 and the lower frame 12 through the pinch roller 141. The setting of the pinch roller 141 not only enables the workbench 14 to be fixed and limited to the upper frame 11 and the lower frame 12 in a clamped form, but also the pinch roller 141 is in rolling contact with the upper frame 11 and the lower frame 12, greatly reducing the friction between the pinch roller 141 and the upper frame 11 and the lower frame 12, thereby reducing the driving load of the driving motor 151 and improving the driving effect of the driving motor 151. When driving the workbench 14 to the next staff member, control the driving motor 151 to stop. At this time, this staff member performs specific assembly or processing tasks on the vehicle wire harness on the workbench 14. After the specific assembly or processing tasks are completed, control the driving motor 151 to drive the workbench 14 to drive the wire harness to the next staff member for specific assembly or processing tasks. And the tooth 161 is slidably connected in the groove 162 to facilitate the disassembly and replacement of the conveyor belt 152. That is, when the conveyor belt 152 needs to be disassembled or replaced, the user only needs to control the electromagnetic sheet 163 to be energized, so that the electromagnetic sheet 163 can generate a magnetic adsorption force on the tooth 161, so that the tooth 161 extends out of the tooth groove 153 and away from the conveyor belt 152 under the adsorption of the electromagnetic sheet 163, so that the tooth 161 away from the conveyor belt 152 can squeeze the connecting spring 164 into the groove 162, thereby facilitating the user to remove the conveyor belt 152 separated from the tooth 161 from the lower end of the upper frame 11, greatly reducing the disassembly and replacement difficulty of the conveyor belt 152, and further improving the maintenance efficiency of the staff, so that the practicability of the present utility model is further improved.

[0031] Embodiment 2, the difference compared with Embodiment 1 is that:

[0032] A cylindrical groove 17 is formed at the upper end of the turntable 16; a screw 171 is threadedly connected in the cylindrical groove 17; an oil passage 172 is formed at the bottom of the cylindrical groove 17; one end of the oil passage 172 away from the cylindrical groove 17 communicates with the groove 162.

[0033] In this embodiment, a baffle 173 is rotatably connected to the upper end of the turntable 16; the baffle 173 is L-shaped; the screw 171 is made of PTFE material;

[0034] During operation, although the electromagnetic sheet 163 and the connecting spring 164 are provided, the electromagnetic sheet 163 can enter and exit the groove 162 by adsorbing the tooth 161, so that the connection and separation between the tooth 161 and the transmission belt 152 can be quickly switched. However, in a humid or dusty environment, the electromagnetic sheet 163 is prone to short circuit or open circuit, resulting in abnormal operation. Moreover, during the repeated compression and release of the connecting spring 164, material fatigue occurs, resulting in a decrease in the elasticity and strength of the spring, and thus it is prone to breakage. To address this, the present utility model provides a screw 171. Since the screw 171 is threadedly connected in the cylindrical groove 17 and the cylindrical groove 17 is filled with hydraulic oil, when the user rotates the screw 171 into the cylindrical groove 17, the screw 171 can squeeze the hydraulic oil in the cylindrical groove 17 to enter the groove 162 through the oil passage 172, so that the hydraulic oil entering the groove 162 can push the tooth 161 out of the groove 162, thereby enabling the tooth 161 extending out of the groove 162 to insert into the tooth groove 153 on the inner wall of the transmission belt 152, so that the turntable 16 is meshed and driven with the transmission belt 152 through the tooth 161. When it is necessary to remove the transmission belt 152, only need to rotate the screw 171 in the reverse direction, so that the screw 171 can be spirally extended out of the cylindrical groove 17, so that the hydraulic oil in the cylindrical groove 17 is no longer pushed by the screw 171, and the space in the cylindrical groove 17 increases. At this time, a negative pressure is generated in the cylindrical groove 17, so that the hydraulic oil in the groove 162 flows back to the cylindrical groove 17 through the oil passage 172. And the screw 171 is made of PTFE material, so that the screw 171 made of PTFE material has the characteristics of smooth surface and corrosion resistance, so that the screw 171 not only has a low friction coefficient with the cylindrical groove 17, but also can resist the corrosion of hydraulic oil, so that the service life of the screw 171 is improved. Moreover, by providing the baffle 173, after the screw 171 pushes the hydraulic oil in the cylindrical groove 17 into the groove 162, by rotating the baffle 173, the baffle 173 can block the mouth of the cylindrical groove 17, preventing foreign dust and other impurities from entering and blocking the cylindrical groove 17, thereby facilitating the user to rotate the screw 171, and further improving the practicality of the present utility model.
