[0110] Preferably, the conveying baffle 931 near the outlet end of the conveying track 91 can be inserted into the lower side of the assembly of the third part 120 and the fourth part 110 to support the assembly of the third part 120 and the fourth part 110 to move to a position away from the conveying track 91.

[0111] Further, as shown, Figure 14As shown, the assembly device of the conductive system further comprises a fastener secondary assembly mechanism 7 for pre-pressing the conductive system 100 and inserting the fastener 150 inserted into the connecting hole 160 on the fourth part 110 and the third part 120 into the connecting hole 160 on the second part 130 and the first part 140.

[0112] Specifically, as shown in the drawings, Figure 14 The fastener secondary assembly mechanism 7 comprises a pre-pressing assembly 71, a guide rod assembly 72 and a pressing rod assembly 73. The pre-pressing assembly 71 comprises a pre-pressing rod 711 arranged above the positioning clamp 300, which can move up and down relative to the positioning clamp 300 to press the fourth part 110 to make the fourth part 110, the third part 120, the second part 130 and the first part 140 fit together. The guide rod assembly 72 is arranged below the fastener 150 and comprises a guide rod 721 which moves up and down relative to the fastener 150 to abut the lower end of the fastener 150. The pressing rod assembly 73 is arranged above the fastener 150 and comprises a pressing rod 731 which can move up and down relative to the fastener 150 to press the upper end of the fastener 150 and press the fastener 150 into the connecting hole 160 on the second part 130 and the first part 140. After the assembly body of the fourth part 110 and the third part 120 is placed on the positioning clamp 300 and positioned with the second part 130 and the first part 140, the pre-pressing rod 711 is first used to press downward on the uppermost fourth part 110 to make the fourth part 110, the third part 120, the second part 130 and the first part 140 fit together to an assembled state, then the guide rod 721 and the pressing rod 731 are respectively abutted to the two ends of the fastener 150, and the pressing rod 731 is pressed against the fastener 150 to move downward to abut the fourth part 110 to facilitate subsequent locking of the fastener 150. The guide rod 721 plays a guiding role during the movement of the fastener 150, which is beneficial to improving the assembly precision of the fastener 150 with the fourth part 110, the third part 120, the second part 130 and the first part 140.

[0113] Preferably, since the second part 130 extends above the fourth part 110, obstructing the fourth part 110, the preload rod 711 cannot press against the center of the fourth part 110. Therefore, two preload rods 711 are provided, each passing through both sides of the second part 130 to press against the fourth part 110. The preload assembly 71 also includes a preload rod connecting plate 712, on which the two preload rods 711 are slidably disposed. A spring is also fitted onto each preload rod 711 to provide a buffer for its pressing action. To drive the pressing rod 731 to move up and down, such as... Figure 14 As shown, the pre-compression assembly 71 also includes a pre-compression rod cylinder 713 and a pre-compression rod mounting plate 714. The fixed end of the pre-compression rod cylinder 713 is disposed on the pre-compression rod mounting plate 714, and the driving end of the pre-compression rod cylinder 713 is connected to the pre-compression rod connecting plate 712 to drive the pre-compression rod connecting plate 712 to move up and down, thereby driving the pre-compression rod 711 to move up and down to press against the fourth part 110.

[0114] Preferably, such as Figure 14 As shown, to secure the preload rod mounting plate 714, a fixed plate 600 is installed above the indexing turntable 200. The fixed plate 600 is fixed to the mounting base 400 and spaced a certain distance from the indexing turntable 200 to prevent interference with the rotation of the indexing turntable 200. The bottom end of the preload rod mounting plate 714 is fixed to the fixed plate 600, which provides support for the preload assembly 71 and facilitates the spatial layout of the preload assembly 71.

[0115] Furthermore, such as Figure 14 As shown, the pressure rod assembly 73 also includes a second pressure rod drive cylinder 732. The drive end of the second pressure rod drive cylinder 732 is connected to the pressure rod 731 to drive the pressure rod 731 to move up and down. There are two pressure rods 731, and both pressure rods 731 are connected to the same second pressure rod drive cylinder 732 to simultaneously press against the two fasteners 150.

[0116] Furthermore, such as Figure 14 As shown, the guide rod assembly 72 also includes a guide rod drive cylinder 722. The fixed end of the guide rod drive cylinder 722 is connected to the mounting base plate 500, and the drive end of the guide rod drive cylinder 722 is connected to the guide rod 721 to drive the guide rod 721 to move up and down.

[0117] Preferably, one of the guide rod 721 and the fastener 150 is provided with a guide groove 151, and the other is provided with a guide protrusion 7211.

The locking mechanism 10 is used to lock the fourth part 110, the third part 120, the second part 130, and the bimetallic strip using the fastener 150. The conductive system 100, after being assembled by the secondary fastener assembly mechanism 7, moves in position as the indexing turntable 200 rotates, moving to the locking mechanism 10 to lock the fastener 150.

[0119] In this embodiment, the fastener 150 is a rivet, which achieves a locking effect through the rivet shank end of the cold-riveting rivet. The equipment used for cold riveting is a riveting machine. Specifically, the locking mechanism 10 includes a first rivet head 101 and a second rivet head 102. The first rivet head 101 and the second rivet head 102 are located at opposite ends of the rivet and can approach each other to cooperate with the rivet shank end of the cold-riveting rivet, thereby achieving the complete assembly of the conductive system 100. Riveting machines are commonly used equipment in the prior art, and their detailed structure and working principle will not be described in detail here.

[0120] After assembly, the conductive system 100 continues to move with the indexing turntable 200, and is removed from the positioning fixture 300 after avoiding the locking mechanism 10. The positioning fixture 300 continues to move with the indexing turntable 200 to the first part loading mechanism 1, and then loads the next part into the first part loading mechanism 1.

[0121] Work process:

[0122] First, the indexing turntable 200 rotates, causing a positioning fixture 300 to rotate to the first part loading mechanism 1, and the first part loading mechanism 1 inserts the first part 140 into the positioning fixture 300.

[0123] Then, the indexing turntable 200 continues to rotate, causing the positioning fixture 300 carrying the first part 140 to rotate to the second part feeding mechanism 2. The second part feeding mechanism 2 inserts the second part 130 into the positioning fixture 300. The indexing turntable 200 continues to rotate, causing the positioning fixture 300 carrying the first part 140 and the second part 130 to rotate to the fastener secondary assembly mechanism 7.

[0124] While the first part 140 and the second part 130 are being assembled, the third part 120 and the fourth part 110 are being assembled simultaneously. The third part loading mechanism 4 places the third part 120 on the carrier 32 on the rotary platform 31, and the rotary drive assembly drives the carrier 32 carrying the third part 120 to move to the fourth part loading mechanism 5.

[0125] Then, the fourth part loading mechanism 5 places the fourth part 110 on the carrier 32 carrying the third part 120;

[0126] After that, the positioning clamping plate 811 of the third and fourth part assembling mechanism 8 pushes the third part 120 to move to the lower side of the fourth part 110, so that the positioning protrusion 121 on the third part 120 is aligned with the positioning hole 111 on the fourth part 110, the pressing column 821 is pressed down, the positioning protrusion 121 is inserted into the positioning hole 111, and the third part 120 is attached to the fourth part 110 to realize the alignment and assembly of the two;

[0127] After that, the third and fourth part transfer clamp 92 clamps and transfers the assembled third part 120 and the fourth part 110 to the conveying track 91, the conveying baffle 931 pushes the third part 120 and the fourth part 110 to move to the lower side of the fastener primary assembling mechanism 6, the fastener primary assembling mechanism 6 inserts the fastener 150 into the connecting hole 160 on the third part 120 and the fourth part 110, and the conveying baffle 931 continues to push the third part 120 and the fourth part 110 to move to the positioning clamp 300, so that the fourth part 110, the third part 120, the second part 130 and the first part 140 are stacked in sequence;

[0128] After that, the fastener secondary assembling mechanism 7 presses the fastener 150 into the connecting hole 160 on the second part 130 and the first part 140, so that the fastener 150 connects the fourth part 110, the third part 120, the second part 130 and the first part 140;

[0129] Finally, the indexing turntable 200 rotates, the positioning clamp 300 carrying the fourth part 110, the third part 120, the second part 130 and the first part 140 moves to the locking mechanism 10, the locking mechanism 10 fixes the fastener 150, so that the fastener 150 locks the fourth part 110, the third part 120, the second part 130 and the bimetallic strip, and the assembly of the conductive system 100 is completed.
