[0096] When the flip driving unit 233 drives the cover pressing seat 2322 to flip toward the positioning protrusion 2312 through the rotating shaft 2321, the clamping member 2323 presses the first workpiece 810 on the positioning protrusion 2312 through the clamping arc surface 2323a, which is beneficial to improve the stability of the cover pressing mold group 232 pressing the first workpiece 810. At this time, the positioning pin 2325 is inserted into the corresponding positioning hole 2313 to position the clamping member 2323 on the positioning protrusion 2312, which is beneficial to improve the accuracy of the cover pressing mold group 232 pressing the first workpiece 810. In addition, the adsorption member 2324 adsorbs the spring piece 830 and drives the spring piece 830 and the first pin 840 to respectively contact with the first workpiece 810.

[0099] Please refer to Figure 3 In this embodiment, the first workpiece 810 is provided with a first through hole 8102 which passes through the opposite side walls of the first workpiece 810 and is connected to the mounting groove 8101, and the assembly protrusion 8201 of the second workpiece 820 is provided with a second through hole 8203. When the assembly protrusion 8201 extends into the assembly groove 8101, the second through hole 8203 is opposite to and connected to the first through hole 8102. When the assembly device 100 of this embodiment assembles the product 800, it is also necessary to pass the second pin 850 through the first through-hole 8102 and the second through-hole 8203 to connect the first workpiece 810 and the second workpiece 820, wherein the process of the assembly device 100 connecting the first workpiece 810 and the second workpiece 820 through the second pin 850 is as follows: the second pin 850 is placed in the storage groove 51, the storage groove 51 receives the second pin 850 and guides the moving direction of the second pin 850, the push member 60 drives the push rod 70 to move toward the storage member 50, and the push rod 70 pushes the second pin 850 to slide along the storage groove 51 and insert into the first through-hole 8102 and the second through-hole 8203, thereby helping to improve the efficiency and accuracy of the assembly device 100 in connecting the first workpiece 810 and the second workpiece 820 through the second pin 850.

[0100] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8The pressing mechanism 40 includes a sliding seat 41, a pressing head 42 connected to the sliding seat 41, an elastic guide assembly 43, a buffer guide rod 44, and a displacement sensor 45 connected to the buffer guide rod 44. The sliding seat 41 is slidably disposed on the second slide rail 15 along the second direction and is connected to the pressing drive member 30. The sliding seat 41 has an abutting protrusion 411 extending toward the guide member 21; the pressing head 42 is rotatably disposed on the sliding seat 41 and is located on one side of the abutting protrusion 411. Both ends of the elastic guide assembly 43 are respectively connected to the abutting protrusion 411 and the pressing head 42. The buffer guide rod 44 passes through the sliding seat 41 and extends to the guide member 21. The buffer guide rod 44 may be a hydraulic telescopic rod. The displacement sensor 45 is disposed at one end of the buffer guide rod 44 close to the guide member 21. The displacement sensor 45 is a contact sensor. In the process of the pressing mechanism 40 pushing the first pin 840, the pressing drive member 30 drives the pressing head 42 to push the first pin 840 to move along the first guide groove 211 toward the second workpiece 820 through the sliding seat 41. The pressing head 42 swings along the movement trajectory of the first pin 840 when the first pin 840 moves along the first guide groove 211 toward the second workpiece 820, which is conducive to improving the accuracy of the pressing head 42 pushing the first pin 840 to connect the first pin 840 with the second workpiece 820. The elastic guide component 43 guides the swing direction of the pressing head 42 and is used to adjust the pressure when the pressing head 42 is disengaged from the first pin 840. The pressure head 42 is driven back to its original position, which is beneficial to improving the accuracy of the pressure head 42 pushing the first pin 840 and making it convenient for the assembling device 100 to accurately push the first pin 840 when the product 800 is assembled again. The displacement sensor 45 senses whether the sliding seat 41 and the pressure head 42 have moved into place by abutting against the guide member 21, thereby effectively preventing the sliding seat 41 from driving the pressure head 42 to over-press the first pin 840. The buffer guide rod 44 buffers the displacement sensor 45 when the displacement sensor 45 abuts against the guide member 21, thereby preventing the displacement sensor 45 from being damaged due to the rigid abutment with the guide member 21.

[0101] In this embodiment, the end of the pressing head 42 facing the guide member 21 has two spaced extrusion protrusions 421, and a clearance notch 422 for avoiding the spring sheet 830 is formed between the two extrusion protrusions 421, so as to avoid the interference between the pressing head 42 and the spring sheet 830 when pushing the first plug pin 840. The ends of the two extrusion protrusions 421 facing the guide member 21 are both provided with extrusion grooves 4211 for pushing the first plug pin 840. When the pressing head 42 pushes the first plug pin 840, the two extrusion grooves 4211 push the two ends of the first plug pin 840 respectively, so as to improve the stability of the pressing head 42 pushing the first plug pin 840, and can effectively reduce the probability of the first plug pin 840 and the pressing head 42 being separated.

[0106] The positioning drive member 22 drives the positioning seat 231 to approach the guide member 21 along the first direction, and the limiting groove 2311 abuts against the second workpiece 820 and limits the second workpiece 820 from moving between the positioning seat 231 and the guide member 21. At this time, the assembly protrusion 8201 of the second workpiece 820 extends into the assembly groove 8101 of the first workpiece 810, the first guide groove 211 abuts against the first pin 840, and the second guide groove 212 abuts against the spring piece 830;

[0107] The push member 60 drives the push rod 70 to move toward the receiving member 50 , and the push rod 70 pushes the second insertion pin 850 to slide along the receiving groove 51 and insert into the first through hole 8102 of the first workpiece 810 and the second through hole 8203 of the second workpiece 820 ;

[0108] The pressing drive member 30 drives the sliding seat 41 to move toward the guide member 21, and the sliding seat 41 drives the pressure head 42 to push the first pin 840 so that the first pin 840 moves along the first guide groove 211 toward the second workpiece 820 and is connected with the slot 8202 of the second workpiece 820.
