DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The present application embodiment discloses a vehicle wiring harness tape wrapping assembly line operation frame, such as Figure 1 and 2 As shown, it includes a water flow rack 3, a plurality of base frames 16 and a plurality of operating tables 1. The water flow rack 3 is fixedly connected to the ground, and a conveying mechanism 34 is arranged on it. The number of base frames 16 is the same as that of the operating tables 1, and the operating tables 1 are installed on the base frames 16. The conveying mechanism 34 is used to make each base frame 16 carrying the operating table 1 move around the water flow rack 3 in a circular manner, and each station of the strapping assembly line is arranged in sequence along the moving direction of the base frame 16.

[0037] like Figure 1 As shown, the transmission mechanism 34 includes a driving source 31, a transmission wheel 32 and a transmission chain 33. In this embodiment, the driving source 31 is a driving motor. There are two transmission wheels 32 and both are rotatably connected to the water flow rack 3. The transmission chain 33 passes through the two transmission wheels 32 and forms a closed loop. The output shaft of the driving motor is coaxially fixedly connected to one of the transmission wheels 32, and the rotation plane of the transmission wheel 32 is a horizontal plane. Each chassis 16 is hinged to the transmission chain 33. One side of the chassis 16 is rotatably connected with a guide wheel 161. The rotation plane of the chassis 16 relative to the transmission chain 33 and the rotation plane of the guide wheel 161 relative to the chassis 16 are parallel to the horizontal plane. The bottom of the chassis 16 is installed with a bottom wheel 162, which is a universal wheel. The wheel surface of the bottom wheel 162 is in direct contact with the ground and rolls relatively. When the conveying mechanism 34 drives each base frame 16 to move in a circular motion through chain transmission, the wheel surface of the guide wheel 161 is in direct contact with the side edge of the water flow rack 3 and rolls relatively thereto, and the guide wheel 161 and the bottom wheel 162 jointly support and guide the base frame 16, thereby improving the state stability of the base frame 16 carrying the operating table 1 during the movement process.

[0038] like Figure 2As shown, the operating table 1 is composed of a rectangular steel frame 11 and two plastic plates 12 which are fixedly connected to each other. The two plastic plates 12 are arranged side by side, and the plates facing away from each other are both the table tops of the operating table 1. A positioning component 2 is arranged on the operating table 1, and the positioning component 2 includes a plurality of guide forks 21 and a plurality of plug blocks 22. The guide forks 21 and the plug blocks 22 are fixedly mounted on the plastic. At the same time, a drawing is also attached to the table top of the operating table 1, and an indicator mark 13 is displayed on the drawing. The indicator mark 13 is used to show the direction of the cable 6 corresponding to a certain model of the finished wire harness. The position of the guide fork 21 corresponds to the branch point or turning point of the cable 6 on the indicator mark 13, and the position of the plug block 22 corresponds to the terminal position on the indicator mark 13. The plug block 22 is provided with a slot for temporary insertion of the terminal. When performing assembly line operation, the operator is located on the side of the operating table 1 away from the water table. In this embodiment, the indicator marks 13 on the two tables of the operating table 1 correspond to two different models of finished wire harnesses, that is, the positioning component 2 and the indicator mark 13 are arranged on both tables of the operating table 1. The operating table 1 is rotatably connected to the base frame 16, and the rotation plane of the operating table 1 is a vertical plane and is parallel to the table top of the operating table 1, that is, the two table tops of the operating table 1 can be selectively turned toward the operator by rotating the operating table 1, so as to produce different types of wire harnesses, thereby improving equipment utilization.

[0039] like Figure 2 and 3 As shown, a limit assembly 4 is provided on the operating table 1, and the limit assembly 4 is used to keep the operating table 1 stationary relative to the base frame 16 during operation, and the limit assembly 4 includes a limit sleeve 42, a stop pin 44 and a limit pin 41. The limit sleeve 42 is fixedly mounted on the base frame 16 and is located at the side of the operating table 1, and the axis of the limit sleeve 42 is parallel to the rotation axis of the operating table 1, and the limit pin 41 is coaxially sleeved in the limit sleeve 42; a limit hole 14 is provided on the steel frame 11 of the operating table 1, and the limit hole 14 is used for inserting the limit pin 41. When the limit pin 41 is inserted into the limit hole 14, the operating table 1 cannot rotate relative to the base frame 16. There are six limit holes 14 into which a single limit pin 41 can be inserted, and each group of three limit holes 14 forms a group. When one of the table surfaces of the operating table 1 faces the operator, one limit pin 41 corresponds to a group of limit holes 14. The limit pins 41 are inserted into different limit holes 14, and the inclination angle of the table surface of the operating table 1 can be slightly adjusted.

[0040] like Figure 3As shown, a guide groove 43 is provided on the wall of the limiting sleeve 42. The guide groove 43 is L-shaped and includes an advance and retreat section 431 and a locking section 432 that are interconnected. The length direction of the advance and retreat section 431 is consistent with the axial direction of the limiting sleeve 42, and the locking section 432 is located on the side of the advance and retreat section 431 facing the operating table 1. One end of the stop pin 44 is fixedly connected to the side wall of the limiting pin 41, and the other end extends out of the limiting sleeve 42 through the guide groove 43; when the stop pin 44 is located in the advance and retreat section 431, the limiting pin 41 can move along its own axial direction in the limiting sleeve 42, and when the stop pin 44 is located in the locking section 432 but not in the advance and retreat section 431, the end of the limiting pin 41 has been inserted into the limiting hole 14, and the limiting pin 41 cannot move along the axial direction, that is, it cannot be easily withdrawn from the limiting hole 14.

[0041] like Figure 2 As shown, a receiving cloth bag 17 is fixedly installed on the bottom frame 16 and at the lower edge of the operating table 1. The bag opening of the receiving cloth bag 17 faces the operating table 1 and is used to receive materials such as cables 6 or terminals that accidentally fall from the operating table 1. A raw material box 18 for holding cables 6 is also provided on the table top of the operating table 1. The box opening of the raw material box 18 is located on the side away from the receiving cloth bag 17. Batches of cable 6 raw materials can be placed in the raw material box 18 for direct access by the operator.

[0042] like Figure 4 and 5 As shown, the raw material box 18 is rotatably connected to the operating table 1, and the rotation plane of the raw material box 18 is parallel to the table surface of the operating table 1; a motorized assembly 5 is arranged inside the operating table 1, and the motorized assembly 5 is used to control the rotation of the raw material box 18 along with the rotation of the operating table 1, and the motorized assembly 5 includes a motorized gear 51, a motorized rack 52 and a reset spring 53. A mounting block 15 is fixedly connected to the side of the plastic plate 12 of the operating table 1 away from the raw material box 18, and the mounting block 15 is passed through by the motorized rack 52 and the two are slidably connected, and the sliding direction of the motorized rack 52 is parallel to the rotation axis of the operating table 1. The motorized gear 51 is coaxially fixedly connected with the rotating shaft of the raw material box 18, and the motorized gear 51 is meshed with the motorized rack 52. A force plate 521 is welded and fixed to one end of the motorized rack 52 facing the limiting sleeve 42. When the limiting pin 41 is inserted into the limiting hole 14, the end of the limiting pin 41 will abut against the force plate 521, and the return spring 53 is passed through the motorized rack 52. One end of the return spring 53 is fixedly connected to the side of the force plate 521 away from the limiting pin 41, and the other end is fixedly connected to the mounting block 15. The return spring 53 always applies a thrust to the force plate 521 so that the force plate 521 and the motorized rack 52 always have a tendency to move close to the limiting pin 41.

[0043] like Figure 4 and 5As shown, when the limit pin 41 is inserted into the limit hole 14, the limit pin 41 pushes the force plate 521 and the motorized rack 52, and when the stop pin 44 is located in the locking section 432, the box opening of the raw material box 18 faces directly opposite to the material receiving cloth bag 17; when the limit pin 41 is withdrawn from the limit hole 14, the reset spring 53 pushes the force plate 521 and the motorized rack 52, and the motorized gear 51 and the raw material box 18 rotate at the same time until the force plate 521 abuts against the inner side of the steel frame 11, and at this time, the box opening of the raw material box 18 faces the material receiving cloth bag 17. When the limit assembly 4 releases the anti-rotation effect on the operating table 1, the raw material box 18, which can normally place raw materials, automatically flips over, so that the materials in the raw material box 18 that have not been taken out in time can actively slide into the material receiving cloth bag 17, reducing the probability of residual materials accidentally falling to the ground and being lost when flipping the operating table 1.

[0044] The implementation principle of the automotive wiring harness tape wrapping assembly line rack in the present application embodiment is as follows:

[0045] Each operator is located at each workstation, the driving source 31 is started, and each chassis 16 starts to move slowly with the operating table 1. Each operating table 1 passes each operator in turn. At that time, the operator performs the cable 6 bundling step for which he is responsible on the operating table 1. When the operating table 1 leaves a workstation, the cable 6 attached to it is still "fixed" on the operating table 1 through the positioning component 2. The operator at the next workstation can continue processing according to the indicator mark 13 until the finished wire harness is assembled and can be removed from the operating table 1 as a whole.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
