[0001] The invention relates to the technical field of safety belt assembly equipment, and in particular to a narrow ribbon threading and sewing integrated machine and a control method thereof. Background Art

[0002] With the development of science and technology, cars are becoming more and more popular, which means that their production capacity is getting higher and higher. Safety, as one of the important performance indicators of cars, is always an existence that cannot be ignored. Seat belts can play a direct role in safety performance, and their importance is self-evident. Therefore, the output and quality of seat belts have become a demand, and automated assembly production has become inevitable.

[0003] Traditionally, the automation level of webbing threading is low, and the threading of webbing is basically assisted by tooling and fixtures. In addition, the product compatibility is poor, and the position of the tooling needs to be adjusted every time the length of the webbing is changed. The biggest problem is that manual labor is required for the threading, folding, sewing and other processes of the webbing, which not only wastes manpower but also has low production efficiency.

[0012] A control method for a narrow ribbon threading and sewing machine, comprising the following steps: Step 1: Place the buckle assembly and fixing plate from the shelf outside the equipment into the left and right fixtures corresponding to the loading assembly, and then place the webbing from the material box outside the equipment into the webbing carrier.

[0013] Step 2: The operator takes his hands off the equipment and starts the equipment. At this time, the light curtain detector cannot detect any object, and after the optical fiber detector detects that the webbing is in place, the equipment starts to carry out the webbing threading process.

[0014] Step 3: The belt pressing cylinder extends out, driving the pressing plate to descend and press the webbing, and then the webbing carrier moves toward the clamping claw, and the clamping claw cylinder drives the clamping claw to contract and clamp the webbing, completing the webbing pulling action.

[0015] Step 4: Then the two telescopic electric cylinders move back to back to set the distance between the buckle assembly and the fixed plate. After the distance adjustment is completed, the tensioning cylinder descends to make the fixed plate close to the webbing. Then the right and left lifting cylinders extend at the same time to lift up both sides of the webbing. Then the side flip cylinder drives the loading plate to rotate, so that the webbing on both sides completes the folding action.

[0016] Step 5: After the webbing is folded to the buckle assembly and the fixing plate, the turntable rotates to the transfer robot arm, and the product is moved from the feeding assembly to the sewing assembly through the transfer robot arm.

[0017] Step 6: At the sewing machine, the floating limit plate and the fixed limit plate work together to ensure the neatness of the webbing. Then the transfer robot arm places the product on the carrier plate, and the sewing cylinder drives the sewing pressure block to press the webbing. Then the transfer robot arm exits the sewing position and waits for the next product on the turntable to arrive.

[0018] Step 7: After the transfer robot arm leaves, the sewing download plate moves according to the set program route, and the sewing needle and thread above are output, thus completing the sewing process of the ribbon.

[0019] Preferably, the transfer clamp is based on the buckle assembly side, the buckle assembly supporting plate is in contact with the buckle assembly, and the position is adjusted by the transfer electric cylinder according to the required length of the webbing so that the fixed plate supporting plate fits with the fixed plate, and then the pressing cylinder is lowered to make the transfer pressure block contact with the webbing to prevent the webbing from recovering during the movement of the robot. At the same time, the floating limit plate is in contact with the side of the webbing to ensure that the webbing will not be scattered.

[0020] Preferably, sewing components are provided on both sides of the transverse conveyor belt to match the conveying time of the loading component and the transfer robot arm. Finally, the buckle assembly and the fixing plate are respectively wrapped and sewn with the webbing, and the products are transported to the finished product hopper through the transverse conveyor belt and the vertical conveyor belt, waiting to be taken away manually.

[0021] The present invention can achieve the following effects: The present invention provides a narrow ribbon threading and sewing integrated machine and a control method thereof, which, compared with the prior art, has the advantages of compact structure, time-saving, labor-saving and good operation stability. The threading and sewing of the ribbon are mediated by a robot to achieve integrated production, reduce intermediate losses and improve production efficiency. The automation level is high, replacing the manual threading operation mode. The turntable operation mode is adopted, and the double workstations are alternately operated to improve the operation efficiency.

[0022] In terms of automation level, compared with the conventional semi-automatic operation in which people and tooling cooperate with each other, it not only reduces labor intensity and saves labor costs, but also shortens the entire production line product cycle; in terms of operability, only the corresponding three parts are placed in the designated positions, the sensors automatically complete the detection, and the equipment can operate automatically; in terms of structural technology, the webbing threading and sewing processes do not require manual secondary transfer, and can achieve integrated production.
