A mounting frame 2 is fixedly provided at the top of the assembly seat 1, and the mounting frame 2 is vertically arranged at the top of the assembly seat 1. A bracket 8 is fixedly provided on the side of the mounting frame 2. A control module is also provided.

[0025] To store the pins and to keep an eye on replenishment. Figure 2 and Figure 3 In this embodiment, a pin storage frame 3 is fixedly arranged on the mounting frame 2. The pin storage frame 3 is in the form of two rectangular structures with a large upper portion and a small lower portion, and the connection position at the opposite sides of the mounting frame 2 is in the form of an arc transition structure. A large number of pins can be stored, and the pins can be automatically dropped by the arc transition structure. The upper and lower ends of the pin storage frame 3 are both open structures, and the bottom end of the pin storage frame 3 abuts against the top end of the bracket 8, and a slide 10 for the pin to move along the head and tail direction is horizontally opened at the abutting position of the bracket 8. The pin can automatically fall onto the slide 10, which is convenient for the subsequent movement of the pin. An observation slot 11 is vertically opened at one end of the pin storage frame 3 facing away from the mounting frame 2, and an adjustment slot 12 is opened on the bracket 8 below the observation slot 11. The number of pins can be observed in real time and the pins can be moved to unblock after being blocked. A guide block 13 is fixedly arranged on the bracket 8 on the side of the pin storage frame 3, and a guide slot 14 corresponding to the position of the slide 10 is opened through the middle of the guide block 13. It can guide the subsequent movement of the pin.

[0026] In order to realize the pinning operation. In this embodiment, see Figure 2 and Figure 3, a slide rail 9 is horizontally and fixedly arranged on the side of the bracket, and the pin punching block 5 slides on the slide rail 9. A fixed plate 4 is fixedly arranged on the assembly seat 1 on the side of the mounting bracket 2, and a pin punching block 5 which can slide in the horizontal direction and push the pin out of the pin storage frame 3 is arranged on the fixed plate 4. A pneumatic push rod 15 is horizontally and fixedly arranged on the side of the fixed plate 4, and the pneumatic push rod 15 is centrally controlled by a control module. The output end of the pneumatic push rod 15 penetrates through the fixed plate 4 and the pin punching block 5 is fixedly arranged at the end of the pneumatic push rod 15. By controlling the pneumatic push rod 15 to work through the control module, the pin punching block 5 is driven to move on the slide rail 9. A pin punching rod 16 is horizontally and fixedly arranged on the top side of the pin punching block 5, and the pin punching rod 16 is located at the bottom side of the pin storage frame 3 on the opposite side of the guide block 13 and is coaxially arranged with the guide groove 14. By moving the pin punching rod 16, the pin is pushed to be assembled onto the armrest box.

[0027] For limiting the top cover of the armrest box. Specifically, refer to Figure 2 and Figure 3 , a limiting mechanism 6 for fixing the position of the top cover of the armrest box is arranged on the fixed plate 4. The limiting mechanism 6 includes a limiting block 61 fixedly arranged at the top of the fixed plate 4, a sliding rod 62 sliding towards the armrest box direction is arranged on the limiting block 61, and a limiting plate 63 for limiting the armrest box is fixedly arranged at one end of the sliding rod 62 facing the armrest box direction. The top cover of the armrest box is limited and positioned by the limiting plate 63, which is convenient for subsequent pin punching operations. A roller 64 is rotatably arranged at the other end of the sliding rod 62, and a spring 65 is sleeved between the sliding rod 62 on the side of the roller 64 and the limiting block 61. An extrusion rod 66 which can be abutted against the roller 64 is fixedly arranged on the side of the pin punching block 5 facing away from the armrest box, and the abutting surface of the extrusion rod 66 and the roller 64 is an inclined surface gradually thinning towards the tail. By the extrusion rod 66 extruding the roller 64, the extrusion rod 66 overcomes the resistance of the spring 65 to push the limiting plate 63 to move, which is convenient for positioning and limiting the top cover of the armrest box.

[0028] The using method of the pin assembly device based on the automotive armrest box of the present utility model: First, place the assembly seat 1 at a suitable position and fix it on the desktop or workbench through bolts. Then place the pin inside the pin storage frame 3, and then place the base of the armrest box on the clamping block 7 for limiting, and place the top cover of the armrest box on the base and position and limit it through the limiting plate 63. When placing the top cover of the armrest box, the limiting plate 63 is abutted against the limiting block 61 through the spring 65, so as to facilitate the placement of the top cover of the armrest box.

[0029] When the pinning operation is performed, the air push rod 15 is controlled by the control module to work, and the pinning block 5 is moved in the direction of the air push rod 15. In this process, the pinning block 5 moves on the slide rail 9 for guidance, and the pinning rod 16 moves on the slide groove 10, so that the pin shaft slides out of the guide groove 14 along the slide groove 10. At this time, the guide groove 14 plays a guiding role. At the same time, the pinning block 5 drives the extrusion rod 66 to move, and the tail of the extrusion rod 66 abuts against the roller 64. The extrusion rod 66 continues to move, and the roller 64 pushes the slide bar 62 to overcome the resistance of the spring 65 and slide on the limit block 61, so that the limit plate 63 squeezes the top cover of the armrest box, thereby positioning the hinge of the armrest box. At this time, the pinning rod 16 pushes the pin shaft to insert into the hinge, realizing the hinge between the base and the top cover of the armrest box. In this process, the number of pin shafts can be observed in real time through the observation slot 11, and when the pin shaft is blocked, the pin shaft can be adjusted at any time through the adjustment slot 12 to remove the blockage and make the pin shaft fall automatically.

[0030] After the pinning is finished, the air push rod 15 is controlled by the control module to work, and the pinning block 5 is moved away from the armrest box, and each component returns to the initial position. At this time, the armrest box can be removed, and the assembly of the next armrest box pin is carried out.
