The first supporting plate 19 is located directly below the upper tray rack, and the width of the first supporting plate 19 is smaller than the inner spacing of the upper chain. Since the tray 12 generally contains a plurality of parts to be installed, the tray 12 is then stacked one by one. In order to adapt to the needs of automated production, a gap is formed between the outer edges of adjacent trays 12 for easy insertion. During the operation of the upper tray separator, the following operation process is performed: ① The initial position of the first insertion plate 19 is located between the upper chain and the bottom tray 12. At this time, the first insertion plate 19 supports the bottom tray 12 to avoid affecting the transmission of the upper chain; ② The piston rod of the second air cylinder 18 extends upward until the first supporting plate 19 supports the bottom tray 12; ③ The piston rod of the first air cylinder 5 retracts until the first insertion plate 17 is separated from the bottom tray 12; ④ The piston rod of the second air cylinder 18 retracts downward until the first insertion plate 19 is located at the gap formed between the bottom tray 12 and the upper tray 12 adjacent to the bottom tray 12, and the piston rod of the first air cylinder 5 extends and is inserted into the gap; ⑤ The piston rod of the second air cylinder 18 continues to retract downward until the bottom tray 12 is carried on the upper chain; ⑥ The upper chain moves the bottom tray 12 carried thereon to the next station;

[0038] The transmission assembly comprises a transmission chain 1 and a carrier 2; the transmission chain 1 is installed on the support platform; the transmission chain 1 is parallel to the feeding chain; the carrier 2 is a rectangular strip structure, a groove adapted to the shape of the part to be installed is formed in the carrier 2, and the carrier 2 is installed on the transmission chain 1. The feeding chain only needs to realize the feeding and transmission of the part to be installed, such as feeding a lower shell, a PCB board and an upper shell; therefore, the feeding chain needs to be divided into three feeding chains, i.e., a lower shell feeding chain, a PCB board feeding chain and an upper shell feeding chain. The transmission chain 1 needs to not only realize the transmission, but also assemble the parts on the carrier 2; therefore, the transmission chain 1 needs to be an integral chain; the carrier 2 on the transmission chain 1 carries the lower shell to the next station; after the PCB board is installed on the lower shell, the PCB board is transported to the next station by the transmission chain 1; after the PCB board, the lower shell and the upper shell are assembled into one, the assembly is transported to the next station by the transmission chain 1.

[0039] The mechanical arm 3 is installed on the support platform and located between the feeding tray rack and the recycling tray rack; the mechanical arm 3 is adjacent to the feeding chain, and the feeding chain is adjacent to the transmission chain 1.

[0040] Since the controller is generally assembled by a lower shell, an upper shell and a PCB board, after the PCB board is installed on the lower shell, it needs to be burned and tested by FCT (function test), so the part to be installed needs high position accuracy on the carrier 2. In order to improve the position accuracy, the scheme further comprises two blocking strips 8, a first positioning cylinder 7 and an intermediate positioning assembly.

[0041] The blocking strips 8 are respectively installed in parallel on both sides of the middle section of the transmission chain.

[0042] The first positioning cylinder 7 is installed on the support platform and located on one side of the middle section of the feeding chain; the movement direction of the piston rod of the first positioning cylinder 7 is perpendicular to the transmission direction of the feeding chain; the end of the piston rod of the first positioning cylinder 7 can extend above the feeding chain. When the feeding chain transports the tray 12 to the middle section of the feeding chain, the piston rod of the first positioning cylinder 7 extends and pushes the edge of the tray 12 until the tray 12 contacts the blocking strip 8 on the other side to realize the first positioning.

[0043] The intermediate positioning assembly comprises a chassis 14, a first corner positioner 13, a second corner positioner 15, and a fifth cylinder 16. The chassis 14 is provided with a groove matching the shape of the part to be installed, and is installed on the support platform.

The first corner positioner 13 can be in V-shaped structure, and the second corner positioner 15 can be in V-shaped structure. After the robot 3 places the part to be installed on the chassis 14, the piston rod of the fifth cylinder 16 is extended to push the edge of the tray 12 until the tray 12 is in contact with the first corner positioner 13 to realize the second positioning. Then, the robot 3 places the part to be installed on the carrier 2 to realize high-precision positioning.

[0044] Workflow:

[0045] (1) The bottom tray 12 is separated by the feeding tray separator.

[0046] (2) The feeding chain drives the bottom tray 12 to the middle section of the feeding chain.

[0047] (3) The piston rod of the first positioning cylinder 7 is extended to push the edge of the tray 12 until the tray 12 is in contact with the blocking strip 8 on the other side to realize the first positioning.

[0048] (4) The robot 3 places the part to be installed on the chassis 14 in turn. The piston rod of the fifth cylinder 16 is extended to push the edge of the part to be installed until the part to be installed is in contact with the first corner positioner 13 to realize the second positioning.

[0051] (5) The feeding chain drives the empty tray 12 to the bottom of the recycling tray rack. The recycling tray holder operates and completes the support of the bottom empty tray 12.

[0052] (6) Repeat the above process in turn until all operations are completed.
