Then, the insulating tube is rotated by the resistance wire winding mechanism 7, so that the resistance wire is wound around the outer wall of the insulating tube until the winding is completed. After that, the resistance wire is cut by the components inside the resistance wire loading and welding mechanism 6. Then, the resistance value of the assembled components is measured by the resistance value measuring device 8. After the measurement is completed, it can be transported away by the conveyor belt 9.

The cut thermal bimetallic element is pushed forward by subsequent thermal bimetallic elements to enter the insulating tube inside the movable plate 31, thereby completing the sleeve operation of the two.

[0035] Please refer to Figure 3 and Figure 6 A current impact device 431 is installed on the surface of the limiting plate 43 for impacting the current on the cut thermal bimetallic element inside the limiting plate 43 .

[0036] Specifically, the cut thermobimetallic element is tested by the current impact device 431, which can accurately test the performance of the thermobimetallic element when it is subjected to a high-energy instantaneous current impact.

A three-jaw chuck 74 is rotatably connected to the other side of the vertical plate 72. The central axis of the three-jaw chuck 74 is sleeved with the output shaft of the fourth motor 73.

[0041] Specifically, any one of the third conveyor rollers 62 is driven to rotate by the third motor 63, so as to convey the resistance wire wound on the resistance wire winding rod 61 until the resistance wire contacts the thermal bimetal element inside the insulating tube after it extends out. Then, the end of the resistance wire is welded to the thermal bimetal element by the welding device 66. The sleeved insulating tube is positioned by the three-jaw chuck 74. The vertical plate 72 slides on the substrate 71 until the insulating tube disengages from the inside of the movable plate 31. Then, the three-jaw chuck 74 is driven to rotate by the fourth motor 73, so that the resistance wire is wound around the outer wall of the insulating tube. After the winding operation is completed, the third cylinder 64 is driven to move the third cutting knife 65 downward to cut and separate the resistance wire. Then, the resistance value of the assembled component is measured by the resistance value measuring device 8.

[0042] Please refer specifically to Figure 9 , a fifth motor 75 is installed on the base 1, and the output end of the fifth motor 75 is installed on the inner wall of the substrate 71.

[0043] Specifically, the fifth motor 75 drives the substrate 71 to rotate on the base 1, thereby adjusting the orientation of the substrate 71, causing the three-jaw chuck 74 to release the assembled component after molding, and allowing the component to fall onto the conveyor belt 9 for transmission away.

[0044] Please refer specifically to Figure 9 , two sliding grooves 76 are provided inside the substrate 71, and the lower end of the vertical plate 72 is slidably connected inside the sliding grooves 76.

[0045] Specifically, by providing the sliding grooves 76, the vertical plate 72 can move inside the sliding grooves 76, thereby playing a role in limiting the movement of the vertical plate 72.

[0046] Please refer specifically to Figure 9 , a sixth motor 77 is installed on the outer wall of the substrate 71. The output end of the sixth motor 77 is sleeved with a reciprocating lead screw 78. The reciprocating lead screw 78 is rotatably connected inside any one of the sliding grooves 76, and the lower end of the vertical plate 72 is threadedly connected to the outside of the reciprocating lead screw 78.

[0047] Specifically, the sixth motor 77 drives the reciprocating lead screw 78 to rotate, causing the vertical plate 72 to move on the reciprocating lead screw 78, so that the vertical plate 72 can move inside the sliding grooves 76 when moving, thereby being able to drive the component on the three-jaw chuck 74 to displace.

[0048] Working principle: The first motor 21 drives the first conveyor roller 22 to rotate, causing the two gears 23 to rotate in opposite directions, thereby conveying the insulating tube located between multiple first conveyor rollers 22 until the insulating tube enters the other end inside the movable plate 31. After the length positioning of the insulating tube is completed, the first cylinder 24 can be activated to drive the first cutting knife 25 to move downward to cut the insulating tube, making the insulating tube located inside the movable plate 31; The second motor 41 drives any one of the second conveyor rollers 42 to rotate, transmitting the thermal bimetal element located between the two second conveyor rollers 42, causing the thermal bimetal element to enter the limiting plate 43. Then, the second cylinder 44 drives the second cutting knife 45 to move downward, causing the second cutting knife 45 to enter the cutting groove 46, thereby cutting the thermal bimetal element. The cut thermal bimetal element continues to move forward under the push of the subsequent thermal bimetal element and enters the insulating tube inside the movable plate 31, thereby completing the sleeving operation of the two; After the sleeving operation of the insulating tube and the thermal bimetal element is completed, the first electric push rod 3 drives the movable plate 31 to move on the base 1. After the outer wall of the movable plate 31 fits against the side wall of the base 1, the second electric push rod 51 can be activated to drive the cross plate 52 to move, causing the side wall of the cross plate 52 to fit against the side walls of the insulating tube and the thermal bimetal element and move, thereby extending the sleeved insulating tube out of the movable plate 31; The third motor 63 drives any third conveying roller 62 to rotate, thereby conveying the resistance wire wound on the resistance wire winding rod 61 until the resistance wire contacts the thermobimetallic element inside the insulating tube after being extended out, and then the end of the resistance wire is welded to the thermobimetallic element by the welding device 66. After the insulating tube that has been put on is grasped and positioned by the three-jaw chuck 74, the reciprocating screw rod 78 is driven to rotate by the sixth motor 77, so that the vertical plate 72 moves on the reciprocating screw rod 78, so that the vertical plate 72 can move inside the slide groove 76 when moving, thereby driving the insulating tube that has been put on the three-jaw chuck 74 to move. The vertical plate 72 slides on the base plate 71, and the fourth motor 73 drives the three-jaw chuck 74 to rotate, so that the resistance wire is wound around the outer wall of the insulating tube. After the wire winding operation is completed, the insulating tube after winding will be separated from the inside of the movable plate 31, and the third cylinder 64 can drive the third cutting knife 65 to move down to cut and separate the resistance wire. Then, the resistance measuring device 8 is used to measure the resistance of the installed component. Finally, the fifth motor 75 drives the base plate 71 to rotate on the base 1, so as to adjust the orientation of the base plate 71, so that the three-jaw chuck 74 releases the installed component, and the component falls onto the conveyor belt 9 to be transported away.
