[0086] The above is only the preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model.

[0087] The utility model has the following implementation modes based on the above:

[0088] Embodiment 2:

[0089] As shown in Figure 8 ,

[0090] The difference from embodiment 1 is that:

[0091] In the embodiment, the feeding device of the second workpiece 12 adopts a feeding and cutting device 13, which is arranged on the other side of the bearing table 2 and is used for feeding the second workpiece 12. The cutting feeding mode is different from the flying feeding mode in that the second workpiece 12 is in the form of a tape, and the tape has at least one second workpiece 12 to be cut. After the second workpiece 12 is cut and separated from the tape by the feeding and cutting device 13, the subsequent mounting operation can be performed. The remaining structure is the same as that in Embodiment 1.

[0092] The specific mounting steps are as follows:

[0093] The second workpiece 12 to be mounted is fed to the bearing table 2 by manual feeding, the flying feeding device 9 or the feeding and cutting device 13. The number of the second workpieces 12 on the bearing table 2 is the same as the number of the mounting heads 301. The carrier 10 carrying the first workpieces 11 on which the dispensing process has been performed is conveyed to a preset first position by the conveying belt 1011. When the carrier 10 contacts the stop block 1033, the stop block 1033 blocks the further movement of the carrier 10 in the x-axis direction. Then, the jacking cylinder 1021 is started to drive the lifting plate 1022 to lift until the positioning pin 1023 is inserted into the positioning hole. Subsequently, the carrier 10 continues to rise to a preset second position. The three-axis motion mechanism 4 is started to drive the mounting heads 301 to move above the second workpieces 12. The mounting heads 301 pick up the second workpieces 12 synchronously or asynchronously according to a preset program and adjust the assembly posture of the second workpieces 12. The three-axis motion mechanism 4 drives the mounting heads 301 to move above one first workpiece 11 on the carrier 10. The mounting heads 301 synchronously or asynchronously mount the second workpieces 12 on the dispensing area (it should be noted that the dispensing area corresponds to the assembly area of the second workpieces 12 mounted on the first workpiece 11. When multiple second workpieces 12 need to be mounted on one assembly surface of the first workpiece 11, multiple dispensing areas need to be provided on the assembly surface, and each second workpiece 12 corresponds to one dispensing area) of the first workpiece 11. Since multiple first workpieces 11 are carried on each carrier 10, the above mounting steps are repeatedly performed until the mounting task of all the first workpieces 11 on the carrier 10 is completed. After the mounting is completed, the jacking mechanism 102 drives the carrier 10 to descend to the first position (i.e., in contact with the conveying belt 1011). The blocking cylinder 1032 controls the stop block 1033 to descend to a non-blocking position. The conveying belt 1011 conveys the carrier 10 carrying the mounted workpieces to the next process.
