[0003] At present, the elongation rate and resistance value of the enameled wire meet the standards, so the welding requirements for workers are extremely high. In addition, the welding wire is too thin, and long-term work will cause worker fatigue. It is impossible to directly judge whether the welding is qualified, resulting in low product yield and increased production costs. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problems and proposes a welding device for processing curved tire membranes.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a welding device for curved tire membrane processing, which includes a clamping jaw connecting plate, a wire feeding mechanism, a wire breakage detection mechanism, a conducting mechanism, a welding head mechanism and a wire cutting mechanism, the wire feeding mechanism and the wire breakage detection mechanism are both arranged on the clamping jaw connecting plate, the conducting mechanism is connected to the clamping jaw connecting plate through a side plate, the welding head mechanism is arranged on the clamping jaw connecting plate, and the welding head mechanism is located on one side of the conducting mechanism, the wire cutting mechanism is arranged on the side plate, and the wire cutting mechanism is located on one side of the welding head mechanism.

[0012] As a further description of the above technical solution:

[0013] The welding head mechanism comprises a voice coil motor and an ultrasonic welding head. The voice coil motor is fixedly mounted on the clamping claw connecting plate. The ultrasonic welding head is mounted on the voice coil motor via a fixing plate. The fixing plate is connected with a conducting coil.

[0014] As a further description of the above technical solution:

[0015] The tangent mechanism includes a telescopic cylinder, a knife seat and a cutter. The telescopic cylinder is connected to the side plate through a transposition plate. The knife seat is installed on the telescopic end of the telescopic cylinder. The cutter is installed on the knife seat, and the cutter is located on one side of the ultrasonic welding head.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, by installing the clamping claw connecting plate on the mechanical arm, the wire feeding mechanism feeds the enameled wire, and the enameled wire is sent to the welding head mechanism for welding. During the process, the conductor mechanism acts on the enameled wire to ensure that the pulling force and tension of the enameled wire are constant during the wire feeding process. The wire break detection mechanism can detect whether the enameled wire is broken to avoid continuing welding after the enameled wire is broken, resulting in more defective products. After welding is completed, the wire cutting mechanism can cut off the enameled wire. The entire wire feeding and welding process is stable and coherent, which greatly improves the product yield and reduces production costs.

[0018] 2. In the utility model, the enameled wire passes through the damping wheel, the tension sensor and the guide wheel in sequence. The damping wheel applies tension to the enameled wire to ensure that the enameled wire will be straightened during the welding process, and pressure will be generated on the tension sensor, thereby ensuring the stability of the tension sensor and preventing misjudgment. The tension sensor will capture the tension of the enameled wire during the welding process. The detection range is 0-1N and the acquisition speed is 3 times / second. During the normal winding process, the tension of the enameled wire will be maintained within a certain range. We set the minimum value as a threshold. When all the data collected within 1s are lower than the set threshold, it is considered to be broken. At this time, the tension sensor is connected to an external alarm, and the tension sensor sends a signal to the alarm to trigger the alarm to sound an alarm. The guide wheel is used to change the direction of the enameled wire so that the enameled wire can flow smoothly.

[0019] 3. In the utility model, after the enameled wire comes out of the wire feeding mechanism and passes through the guide roller, when the capacitive sensor cannot detect the wire at the guide roller, the capacitive sensor can be connected to an alarm, and the capacitive sensor sends a signal to the alarm to trigger the alarm to sound an alarm.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-3 The utility model provides a technical solution: a welding device for curved tire membrane processing, comprising a clamping jaw connecting plate 1, a wire feeding mechanism 2, a wire breakage detection mechanism 3, a wire guide mechanism 4, a welding head mechanism 5 and a wire cutting mechanism 6, wherein the wire feeding mechanism 2 and the wire breakage detection mechanism 3 are both arranged on the clamping jaw connecting plate 1, the wire guide mechanism 4 is connected to the clamping jaw connecting plate 1 through a side plate 7, the welding head mechanism 5 is arranged on the clamping jaw connecting plate 1, and the welding head mechanism 5 is located on one side of the wire guide mechanism 4, the wire cutting mechanism 6 is arranged on the side plate 7, and the wire cutting mechanism 6 is located on one side of the welding head mechanism 5;

[0027] The wire feeding mechanism 2 includes a fixed column 21 and a wire barrel 22. The fixed column 21 is fixedly mounted on the clamping claw connecting plate 1. The wire barrel 22 is hinged on the fixed column 21. The enameled wire wound on the wire barrel 22 is unwound to prevent the enameled wire from shaking and falling during movement, and to prevent the wire from twisting, tangling, and other situations that affect normal wire feeding.

[0028] The wire mechanism 4 includes a damping wheel 41, a tension sensor 42 and a guide wheel 43. A protective cover 8 is provided on the side plate 7. The damping wheel 41, the tension sensor 42 and the guide wheel 43 are sequentially connected to the protective cover 8. After the enameled wire comes out of the wire break detection mechanism 3, the enameled wire passes through the damping wheel 41, the tension sensor 42 and the guide wheel 43 in sequence. The damping wheel 41 applies tension to the enameled wire to ensure that the enameled wire will be straightened during the welding process, and pressure is generated on the tension sensor 42, thereby ensuring the stability of the tension sensor 42. The tension sensor 42 will capture the tension of the enameled wire during the welding process. The detection range is 0-1N and the acquisition speed is 3 times / second. During the normal winding process, the tension of the enameled wire will be maintained within a certain range. We set the lowest value as a threshold. When all the data collected within 1s are lower than the set threshold, it is considered to be a wire break. At this time, the tension sensor 42 is connected to an alarm. The tension sensor 42 sends a signal to the alarm to trigger the alarm. The guide wheel 43 is used to change the direction of the enameled wire so that the enameled wire can flow smoothly.

[0029] The wire breakage detection mechanism 3 includes a capacitive sensor 31 and a guide roller 32. The capacitive sensor 31 is installed on the clamping jaw connecting plate 1. The guide roller 32 is installed on the clamping jaw connecting plate 1 through a wire breakage detection guide plate 9, and the guide roller 32 is located on one side of the capacitive sensor 31. After the enameled wire comes out of the wire feeding mechanism 2, it passes through the guide roller 32. When the capacitive sensor 31 cannot detect the presence of wire at the guide roller 32, the capacitive sensor 31 can be connected to an alarm. The capacitive sensor 31 sends a signal to the alarm to trigger the alarm to sound an alarm.

[0030] The welding head mechanism 5 includes a voice coil motor 51 and an ultrasonic welding head 52. The voice coil motor 51 is fixedly mounted on the clamping claw connecting plate 1. The ultrasonic welding head 52 is mounted on the voice coil motor 51 through a fixing plate 10. A wire coil 11 is connected to the fixing plate 10. The wire coil 11 has a guiding effect on the enameled wire entering the ultrasonic welding head 52. Under the action of the voice coil motor 51, when the ultrasonic welding head 52 is welding, the ultrasonic welding head 52 applies a constant force to the fetal membrane to ensure a consistent welding effect.

[0031] The wire cutting mechanism 6 includes a telescopic cylinder 61, a knife seat 62 and a cutter 63. The telescopic cylinder 61 is connected to the side plate 7 through a transposition plate 12. The knife seat 62 is installed on the telescopic end of the telescopic cylinder 61. The cutter 63 is installed on the knife seat 62, and the cutter 63 is located on one side of the ultrasonic welding head 52. After the telescopic cylinder 61 is extended, it drives the knife seat 62 to move. The movement of the knife seat 62 drives the cutter 63 to move, and the cutter 63 cuts the enameled wire at the welding point.

[0032] Working principle: First, during welding, the clamping claw connecting plate 1 is installed on the robot arm, the enameled wire is wound on the wire barrel 22, the wire barrel 22 rotates along the fixed column 21, and the enameled wire wound on the wire barrel 22 is released to prevent the enameled wire from shaking and falling during movement, and to prevent the wire from being twisted or knotted during wire feeding, etc., which affect the normal wire feeding. The enameled wire released from the wire barrel 22 passes through the guide roller 32. When the capacitive sensor 31 detects that there is wire at the guide roller 32, the enameled wire passes through the damping wheel 41, The tension sensor 42 and the guide wheel 43, when the capacitive sensor 31 cannot detect the wire at the guide roller 32, the capacitive sensor 31 can be connected to an alarm, and the capacitive sensor 31 sends a signal to the alarm to trigger the alarm to sound an alarm. Secondly, the damping wheel 41 applies tension to the enameled wire to ensure that the enameled wire will be straightened during the welding process, and exert pressure on the tension sensor 42, thereby ensuring the stability of the tension sensor 42 and preventing misjudgment. The tension sensor 42 will capture the enameled wire being stressed during the welding process. The detection range of the tension is 0-1N, and the acquisition speed is 3 times / second. During the normal winding process, the tension of the enameled wire will be maintained within a certain range. We set the minimum value as a threshold. When all the data collected within 1s are lower than the set threshold, it is considered to be a broken wire. At this time, the tension sensor 42 is connected to an external alarm, and the tension sensor 42 sends a signal to the alarm to trigger the alarm to sound an alarm. The guide wheel 43 is used to change the direction of the enameled wire so that the enameled wire can flow smoothly. Then, the enameled wire coming out of the guide wheel 43 passes through the wire coil 11, and the wire coil 11 has a guiding effect on the enameled wire entering the ultrasonic welding head 52. The enameled wire is now attached to the curved fetal membrane. Under the action of the voice coil motor 51, when the ultrasonic welding head 52 is welding, the ultrasonic welding head 52 applies a constant force to the fetal membrane to ensure consistent welding effect. Finally, after the welding is completed, the telescopic cylinder 61 extends and drives the knife seat 62 to move, and the movement of the knife seat 62 drives the cutter 63 to move, and the cutter 63 cuts the enameled wire at the welding point.
