The working principle of the invention is as follows: firstly, a feeding mechanism 4 is started to place injection feet in an injection foot frame 8, then a base plate is placed on the injection foot frame 8, a first self-adaptive mechanism 5 or a second self-adaptive mechanism 6 is used for adjusting, the distance between the injection foot frames 8 is adaptive to the size of the base plate, the injection feet are adaptive to the size of the base plate, then a lower layer conveying strip 2 or an upper layer conveying strip 3 is started to drive the first self-adaptive mechanism 5 or the second self-adaptive mechanism 6 to a nailing mechanism 9, the nailing mechanism 9 is used for binding the injection feet and the base plate together, the lower layer conveying strip 2 or the upper layer conveying strip 3 continuously drive the first self-adaptive mechanism 5 or the second self-adaptive mechanism 6 to a stacking mechanism 10, and the stacking mechanism 10 operates to enable a tray which is nailed and loaded on the first self-adaptive mechanism 5 or the second self-adaptive mechanism 6 to be separated from the lower layer conveying strip 2 or the upper layer conveying strip 3;

wherein the operating principle of feed mechanism 4 is: the injection pins in the feeding tray 11 are conveyed into the feeding barrel 14 by the gears rotating on the first material guiding rail 12 and the second material guiding rail 13, the injection pins enter the material containing block 16 through the feeding barrel 14, the pressing block 17 has a certain interference effect on the injection pins under the action of the spring, so that the pressing pins are temporarily fixed inside the material containing block 16, when the second air cylinder 19 receives an instruction, the second air cylinder 19 presses the pressing rod 18 to move downwards to provide downward pressure for the injection pins in the material containing block 16, so that the injection pins are separated from the material containing block 16 and enter the injection pin frame 8, and the injection pin feeding is completed;

the operation principle of the first self-adaptive mechanism 5 or the second self-adaptive mechanism 6 is as follows: when pulling pull rod 26 or No. two pull rods 27, rack 29 is driven and is stretched into or stretch out fixed cover 28 in, takes place the relative motion with gear 31, and gear 31 rotates, drives No. two rack 30 and stretches into or stretch out fixed cover 28 in, so drive annotates the foot rest 8 at both ends and move in opposite directions or opposite movement simultaneously, with this distance of adjusting annotating between the foot rest 8, until backing plate and the notes foot rest 8 at both ends take place to interfere, make the distance between the foot rest 8 can not change, the size adjustment is accomplished.

The operation principle of the nailing mechanism 9 is as follows: the third air cylinder 33 drives the pneumatic plate 34 to move up and down, the pneumatic plate 34 drives the upper air cylinder 35 and the driven frame 37 to move up and down, the driven frame 37 drives the driven rod 38 to move up and down, the external gear 39 and the third rack 40 are meshed with each other, when the driven rod 38 moves up and down, the external gear 39 and the third rack 40 rotate mutually, the driven frame 37 can be stably driven to move up and down by combining the limiting column 32, the nailing gun 46 is not inclined until the nailing gun 46 is right opposite to the injection foot and the backing plate at the upper end of the first self-adapting mechanism 5 or the second self-adapting mechanism 6, and the upper air cylinder 35 gives power to the nailing gun 46 to assemble the backing plate and the injection foot together;

the operation principle of the stacking mechanism 10 is as follows: the second motor 47 drives the two rolling rods 49 to rotate through a gear and a chain, when the rolling rods 49 rotate, the second gear 50 and the fourth rack 51 are driven to move mutually, the fourth rack 51 is driven to move up and down, when the nailed tray is transported to the upper end of the fourth rack 51 by the lower layer transport strip 2 or the upper layer transport strip 3, the fourth rack 51 moves upwards to drive the tray to the receiving device 52, when the tray is driven to the lower end of the stacking block 54, the tray continues to ascend and interfere with the stacking block 54, the stacking block 54 is driven to rotate, after the stacking block 54 is inserted into a gap in the middle of the tray, the tray starts to move downwards to drive the stacking block 54 to rotate reversely, and when the tail end of the stacking block 54 and the blocking rod 55 are overlapped again, stacking is completed.
