The pressing plate 23 and the plurality of pressing rods 22 are respectively in pressing cooperation with the workpiece in the assembly flow channel 24. The workpiece is held in place in the assembly flow channel 24 under the action of the plurality of pressing rods 22 and the spring 21. In the present invention, the spring pressing mechanism 55 is installed above or below the assembly flow channel 24 as required.

[0023] Specifically, the first transfer mechanism 1 includes a first motor 51, a second motor 52, a first lead screw 49, a second lead screw 47, a first sliding guide rail 26, a second sliding guide rail 10, a first slider 11, a first ball linear guide rail pair 8, a first feeding claw 9, a first bearing roller 14, a roller guide rail 17, a second slider 13, a second ball linear guide rail pair 12, a pushing block 16, a cylinder 15, a second feeding claw 6, a third feeding claw 18, a second bearing roller 25 and a connecting plate 19. The first motor 51 and the second motor 52 are respectively arranged at both ends of the first transfer mechanism body. The first motor 51 and the second motor 52 are respectively connected to the first lead screw 49 and the second lead screw 47. The first lead screw 49 is fixedly arranged on the first sliding guide rail 26 through a first nut 50. The second lead screw 47 is fixedly arranged on the second sliding guide rail 10 through a second nut 48. The second sliding guide rail 10 is fixed on the first slider 11.

The first feeding claw 9, the second feeding claw 6 and the third feeding claw 18 respectively cooperate with the first spring pressing mechanism 5 and the second spring pressing mechanism 7 correspondingly.In the present invention, the FPC connector body is sent to between the jaws of the first feeding claw 9 by other devices. Each time the first feeding claw loads one body, it moves a distance equal to the distance between the jaws in the assembling direction. One feeding claw loads six bodies at a time. After the first feeding claw 9 is filled with bodies, the second motor 52 drives the second lead screw 47 to move along the first ball linear guide 8 in the assembling direction to below the second spring pressing mechanism 7. Then, the air cylinder 15 drives the roller guide 17 to move downward, that is, drives the first feeding claw 9, the second feeding claw 6 and the third feeding claw 18 to move downward together. At this time, the six bodies that were previously between the jaws of the first feeding claw 9 remain in the assembling flow channel 24 and are held in the assembling flow channel 24 by the second spring pressing mechanism 7. Then, the first feeding claw 9 returns to below the initial position. At the same time, the first motor 51 drives the first lead screw 49 to move the second feeding claw 6 to below the second spring pressing mechanism 7. The second feeding claw 6 and the third feeding claw 18 are fixedly connected together by the connecting plate 19 and move synchronously. The third feeding claw 18 moves to below the first spring pressing mechanism 5. After that, the air cylinder 15 drives the three feeding claws to move upward, so that the first feeding claw 9 returns to the initial position to start loading the next batch of bodies. At the same time, the second feeding claw 6 loads the bodies that remained below the second spring pressing mechanism 7 before and moves in the assembling direction. Before reaching the first spring pressing mechanism 5, the insertion of terminals process is completed by cooperating with other devices. Then, the body with terminals inserted is transferred to below the first spring pressing mechanism 5. Through the reciprocating up and down movement of the three feeding claws, the workpiece transfer is realized, and the workpiece with terminals inserted is continuously transferred in the assembling direction.

[0024] Specifically, the second transfer mechanism 2 includes a third motor 53, a first adapter plate 27, a fourth feeding claw 28, a first double-rod air cylinder 29, a third sliding guide 30, a fourth slider 31 and a first linear module 32.

The fourth feeding claw 28 cooperates with the third spring pressing mechanism 33, the fourth spring pressing mechanism 34 and the fifth spring pressing mechanism 35 respectively. In the present invention, the third feeding claw 18 in the first transfer mechanism 1 transfers the workpiece with terminals inserted from below the first spring pressing mechanism 5 to below the third spring pressing mechanism 33, and thus enters the second transfer mechanism 2. The third motor 53 drives the first linear module 32 to move. Under the action of the first linear module 32 and the first double-rod air cylinder 29, the fourth feeding claw 28 moves along Figure 5As shown by the arrow movement in the figure, six workpieces are loaded below the third spring pressing mechanism 33 and moved towards the assembly direction with the workpieces. Before reaching the fourth spring pressing mechanism 34, the process of inserting the lid is completed in cooperation with other devices.

At this time, the sixth feeding claw 44 moves along the Figure 7 direction shown by the arrow in the figure, loads the workpieces above the sixth spring pressing mechanism 39 and moves towards the assembly direction, completes the process of inserting the lid buckle below the spring clamping mechanism 41, and then continues to move in the assembly direction, sending the workpieces to the limit position of the second linear module 40. So far, the workpieces have completed three processes: inserting terminals, inserting lids, and inserting lid buckles. Under the push of the sixth feeding claw 44, the assembled workpieces are continuously arranged and continue to move in the assembly direction along the assembly flow channel and enter the next device.
