The top surface of the workbench 2 is provided with a mounting plate 8, the second driving mechanism comprises a fourth cylinder 82 which is fixed on the top surface of the mounting plate 8 and extends and retracts along the length direction of the workbench 2 and a moving block 81 connected to the driving end of the fourth cylinder 82, and a first limiting groove 811 for clamping and embedding the terminal body 1 is formed in the top surface of one end, far away from the fourth cylinder 82, of the moving block 81. The top surface of the mounting plate 8 is fixed with a fifth cylinder 83 which is consistent with the telescopic direction of the fourth cylinder 82, the driving end of the fifth cylinder 83 is connected with a first connecting block 831 which is perpendicular to the telescopic rod of the fifth cylinder 83, a second groove 812 which is used for the first connecting block 831 to pass through is formed in the top surface of the moving block 81, and the length of the second groove 812 is larger than the width of the first connecting block 831. A second connecting block 832 for pushing the terminal body 1 is fixed on the top surface of the first connecting block 831 through screws, the length direction of the second connecting block 832 is consistent with the telescopic direction of the fourth cylinder 82, and a second limiting groove 84 for clamping and embedding the end part of the terminal body 1 is formed in the end surface of the second connecting block 832. The fourth cylinder 82 pushes the moving block 81 to move, and simultaneously, the fifth cylinder 83 actuates to push the second connecting block 832 to move; after the fourth cylinder 82 pushes the end surface of the moving block 81 to abut against the moving stage 6, the fourth cylinder 82 stops operating, and the fifth cylinder 83 continues to push the second connecting block 832 to move, so that the insert pin 13 is inserted into the terminal body 1. After the assembly is completed, the fourth cylinder 82 and the fifth cylinder 83 are retracted, the second connecting block 832 is retracted, and the assembled terminal slides into the collecting box 26 from the moving block 81 through the guide rail extension 35 under the action of gravity.

Referring to fig. 4, a grabbing mechanism for grabbing the terminal body 1 from the tail end of the guide rail 3 to the first limiting groove 811 is arranged on the top surface of the workbench 2. The grabbing mechanism comprises a U-shaped seat 9 fixed on the top surface of the workbench 2 and a second air cylinder 92 vertically installed on the top surface of the U-shaped seat 9, the driving end of the second air cylinder 92 penetrates through the top surface of the U-shaped seat 9, the driving end of the second air cylinder 92 is connected with a sliding block 91, and the sliding block 91 is just located in a U-shaped groove of the U-shaped seat 9. A third cylinder 93 which extends and retracts along the width direction of the workbench 2 and a clamping jaw 931 connected to the driving end of the third cylinder 93 are fixed on the side surface of the sliding block 91, and a first groove 321 for the clamping jaw 931 to pass through is formed in one end, close to the clamping jaw 931, of the baffle plate 32. Before grabbing, the clamping jaw 931 is located above the first groove 321; then, the second cylinder 92 drives the slider 91 to descend, the clamping jaw 931 grips one terminal body 1 at the tail end of the guide rail 3 downwards, the third cylinder 93 drives the clamping jaw 931 to retreat, and the terminal body 1 is placed in the first limiting groove 811 on the moving block 81, so that the gripping is convenient and fast, and the assembling efficiency is further improved. After the gripping is completed, the second cylinder 92 is returned upward, and the third cylinder 93 is returned so that the holding jaw 931 is returned to above the first recess 321.

The implementation principle of the embodiment is as follows: a plurality of terminal bodies 1 are first placed in the guide rail 3. The pressing block 54 of the second guiding mechanism presses on the guide block 51, and the second guiding mechanism moves the insert pin 13 forwards to be partially extended out of the third guiding mechanism under the driving of the first air cylinder 55, and the extended part is clamped in the clamping groove 63 on the cutting block 622.

At the time of cutting, the push-down cylinder 53 of the third introduction mechanism is lowered to perform press cutting, and the insert pin 13 after cutting is positioned in the notch 63 of the cutting block 622. After the cutting, the hydraulic rod 61 drives the moving table 6 to advance so that the engaging groove 63 communicates with the through groove 751. Meanwhile, the arrangement cylinder 23 pushes the rectangular block 24, and the L-shaped plate 242 rotates around the rotating shaft in the second abdicating groove 241 and then moves into the guide rail 3, so that the terminal bodies 1 are arranged regularly. After photoelectric sensor 25 discerned that the guide rail 3 end has the terminal, second cylinder 92 drive slider 91 descends, and clamping jaw 931 snatchs the terminal body 1 at guide rail 3 end downwards, and third cylinder 93 drives clamping jaw 931 and retreats and places terminal body 1 in spacing groove 811 on movable block 81, snatchs convenient and fast, further improves the packaging efficiency. After the gripping is completed, the second cylinder 92 is returned upward, and the third cylinder 93 is returned so that the holding jaw 931 is returned to above the first recess 321.

Finally, the pushing cylinder 71 pushes the C-shaped block 72, the second pushing rod 722 pushes the second pushing block 74, and the pushing pin 75 extends out of the through groove 751 during the movement of the second pushing block 74, so as to push out the insert pin 13 in the card slot 63. Meanwhile, the fourth cylinder 82 pushes the moving block 81 to move, the fifth cylinder 83 pushes the second connecting block 832 to move, after the fourth cylinder 82 pushes the end surface of the moving block 81 to abut against the moving platform 6, the fourth cylinder 82 stops operating, and the fifth cylinder 83 continues to push the second connecting block 832 to move, so that the insert pin 13 is inserted into the terminal body 1. After the assembly is completed, the fourth cylinder 82 and the fifth cylinder 83 are retracted, the second connecting block 832 is retracted, and the assembled terminal slides into the collecting box 26 from the moving block 81 through the guide rail extension 35 under the action of gravity.

Automatic cycle assembly is realized, so that the assembly efficiency and the assembly quality are improved.
