[0029] The working principle of this embodiment is as follows:
[0030] First, a number of from plate workpieces 13 are arranged in sequence on the from plate placement rack 801, and then the hook tail frame workpiece 11, the buffer workpiece 12 and the hook body workpiece 14 to be assembled are transported to the hook tail frame placement rack 601, the buffer placement rack 701 and the hook body loading unit 9 respectively through production lines, handling equipment, etc., and then a flat pin workpiece 15 is placed in the pin delivery tube 1004 to complete the preparation work before assembly. At this time, the from plate pushing device 803 is driven to push the from plate workpiece 13 to the from plate pushing device 803 at the from plate outlet 804, and the from plate pushing device 803 transfers the from plate workpiece 13 to the side of the buffer workpiece 12 on the buffer placement rack 701 and combines it with the buffer workpiece 12.

At this time, the flat pin mounting unit 10 is started, and the flat pin transverse driving device 1003 is first used to move the pin feeding cylinder 1004 transversely to the bottom of the flat pin mounting holes on the hook body workpiece 11 and the hook body workpiece 14, and then the flat pin longitudinal pushing device 1005 is started to push the flat pin workpiece 15 out of the pin feeding cylinder 1004 and into the flat pin mounting holes on the hook body workpiece 11 and the hook body workpiece 14. The position states of the above-mentioned components when the flat pin workpiece 15 is installed are shown in the attached figure. Figure 2 As shown, the buffer block is then driven to move, and the buffer workpiece 12 gradually returns to a free state. During this period, the elastic force of the buffer presses the hook body workpiece 14, so that the flat pin workpiece 15 is stuck in the flat pin mounting hole under the action of this elastic force, thereby realizing the automated assembly of the hook and buffer components, with high efficiency and better safety.
