In this embodiment, there are 12 positioning fixtures 111, which are equidistantly distributed on the turntable 11. The workbench 10 is circumferentially arranged around the turntable 11 with a loading / unloading module 20, a screw-locking module 40, and an overflow pipe installation module 50. The turntable 11 drives the positioning fixture 111 to pass through the loading / unloading module 20, the screw-locking module 40, and the overflow pipe installation module 50 in sequence before returning to the loading / unloading module 20. The loading / unloading module 20 is used to move the lower cover 70 to the positioning fixture 111. The screw-locking module 40 is used to put the washer 702 on the screw 701 and lock it to the lower cover 70 of the positioning fixture 111. The overflow pipe installation module 50 is used to transfer the overflow pipe 703 and press it to the lower cover 70. Finally, the loading / unloading module 20 removes the lower cover 70 with the installed parts from the positioning fixture 111. This utility model replaces manual operation, has a high degree of automation, high production efficiency, saves labor costs, and avoids missing parts in the lower cover 70.

[0049] like Figure 4-5As shown, the loading / unloading module 20 includes a loading track 201 and a unloading track 202 arranged side by side. A loading robot 203 and an unloading robot 204 are installed at the ends of the loading track 201 and unloading track 202 near the turntable 11. The loading robot 203 is used to pick up the lower cover 70 from the loading track 201 to the positioning fixture 111, and the unloading robot 204 is used to pick up the lower cover 70 from the positioning fixture 111 to the unloading track 202. Specifically, the loading track 201 and the unloading track 202 each include three conveyor belts, with the lower cover 70 placed side by side between two conveyor belts. It can simultaneously convey two rows of lower covers 70. The three conveyor belts that make up the loading track 201 drive in the opposite direction to the three conveyor belts that make up the unloading track 202. The loading robot 203 picks up the lower cover 70 at the end of the loading track 201 and puts it onto the fixture. The unloading robot 204 picks up the lower cover 70 at the front end of the unloading track 202 and puts it onto the fixture. The turntable 11 drives the positioning fixture 111 to rotate one revolution from the loading track 201 and return to the unloading track 202, thus realizing the functions of loading the lower cover 70 of the component to be installed and unloading the installed lower cover 70.

[0050] like Figure 7-12 As shown, the screw-locking module 40 includes a washer feeding mechanism 41, a screw feeding mechanism 42, and a locking mechanism 43. The washer feeding mechanism 41 includes a washer vibratory feeder 411 and a washer 702 picking robot. Specifically, the washer feeding mechanism 41 further includes a support platform 412 and a transfer base 413. The support platform 412 is installed at the transmission end of the washer vibratory feeder 411, and the transfer base 413 is located between the support platform 412 and the moving positioning track. The washer 702 picking robot includes a first chuck 414 and a second chuck 415. The first chuck 414 moves between the support platform 412 and the transfer base 413, and the second chuck 415 moves between the support platform 412 and the transfer base 413. The base 413 moves between the moving positioning track, and the vibratory feeder transmits a single washer 702 to the platform 412. The first chuck 414 of the control washer 702 picking robot picks up the washer 702 on the platform 412 and moves it to the transfer base 413. When the first chuck 414 returns to the platform 412, the second chuck 415 moves to the transfer base 413 and picks up the washer 702. When the first chuck 414 moves to the transfer base 413 again, the second chuck 415 moves the washer 702 to the screw 701 of the screw feeding mechanism 42. This design can improve the efficiency of the washer 702 being fitted onto the screw 701.

[0051] like Figure 7-12As shown, the screw feeding mechanism 42 includes a screw vibratory feeder 421, a moving positioning track, and a blowing channel 423. The screw vibratory feeder 421 is connected to the front end of the moving positioning track, and the blowing channel 423 is located at the end of the moving positioning track. Specifically, the moving positioning track consists of two plates with a gap between them. The screw 701 moves through the gap. A movable horizontal clamping cylinder 4221 and a shift fork 4222 are installed on one side of the moving positioning track along its length. The horizontal clamping cylinder 4221 and the shift fork 4222 are parallel. A vertical clamping cylinder 4223 is installed below the middle of the moving positioning track. The horizontal clamping cylinder 4221 is used to clamp the screw 701 and move it to the vertical clamping cylinder 4223. The vertical clamping cylinder 4223 is used to support the screw 701. The shift fork 4222 moves between the middle of the moving positioning track and the blowing channel 423. The screw vibratory feeder 421 conveys the screw 701 to the front end of the moving positioning track. It controls the horizontal clamping cylinder 4221 to move to the front end and clamp the screw 701 to the vertical clamping cylinder 4223. The horizontal clamping cylinder 4221 and the vertical clamping cylinder 4223 fix the screw 701, so that the second chuck 415 can put the washer 702 on the screw 701. After the screw 701 is fitted with the washer 702, the horizontal clamping cylinder 4221 is released and the screw returns to the moving positioning track. At the same time, the fork 4222 moves to the screw 701 with the washer 702 on it and moves the screw 701 to fall into the blowing channel 423 of the moving positioning track. The screw 701 then passes through the blowing channel 423 to the locking mechanism 43, thus completing the automatic feeding of the screw 701 and the washer 702 and the fitting of the washer 702 onto the screw 701.

[0052] like Figure 7-12 As shown, the guide block 431 has a guide hole, and the fixing block 433 has a moving groove, an input hole 4331, and an insertion hole 4332. The blowing channel 423 is connected to the input hole 4331 through a hose, and the screwdriver 432 is aligned with the insertion hole 4332. Specifically, the screw 701 with the washer 702 on it goes through the blowing channel 423 to the input hole 4331. The input hole 4331 is connected to the moving groove. The guide block 431 is movably inserted into the moving groove. The moving guide hole makes the input hole 4331 aligned with the guide hole, and the screw 701 goes directly to the guide hole. Then the guide block 431 is moved out so that the screw 701 moves to the insertion hole 4332. The screwdriver 432 is aligned with the insertion hole 4332, passes through it, and pushes the screw into the pipe of the lower cover 70. The screwdriver pre-tightens the screw and rotates it. The screwdriver tightens the screw, thus locking the screw 701 with the washer 702 on it in the lower cover 70.

[0053] like Figure 13As shown, the overflow pipe installation module 50 includes an overflow pipe vibratory feeder 501, a positioning base 502, a clamping and moving cylinder, and a lead screw servo cylinder 504. The positioning base 502 and the clamping and moving cylinder are mounted on the edge of the support plate 12. The overflow pipe vibratory feeder 501 conveys the overflow pipe 703 to the positioning base 502. The clamping and moving cylinder moves the overflow pipe 703 above the positioning fixture 111. The lead screw servo cylinder 504 is used to press the overflow pipe 703 onto the lower cover 70. Specifically, the overflow pipe vibratory feeder 501 conveys the overflow pipe 703 to the positioning base 502, the clamping and moving cylinder clamps the overflow pipe 703 and moves it above the lower cover 70, and the lead screw servo cylinder 504 is controlled to press down and press the overflow pipe 703 onto the lower cover 70, thus achieving automatic installation of the overflow pipe 703 onto the lower cover 70. In other embodiments, the lead screw servo cylinder 504 is replaced by a regular cylinder to complete the pressing action. Furthermore, a height detection module is installed on the workbench 10 around the turntable 11 between the overflow pipe installation module 50 and the dispensing module 60. The height detection module includes a position sensor set above the positioning fixture 111. When the lower cover 70 of the overflow pipe 703 is installed, it is moved to the bottom of the height detection module by the turntable to detect whether the overflow pipe 703 is installed in place.

[0054] like Figure 14 As shown, a dispensing module 60 is also provided on the worktable 10 around the turntable 11. The dispensing module 60 includes an X-axis 601, a Y-axis 602, and a vertical movement cylinder 603. The Y-axis 602 is slidably mounted on the X-axis 601, and the vertical movement cylinder 603 is slidably mounted on the Y-axis 602. The piston rod of the vertical movement cylinder 603 is fitted with a glue cylinder 604, with the opening of the glue cylinder 604 facing downwards. Specifically, after the screws 701 and the overflow pipe 703 are installed, the lower cover 70 is rotated by the turntable 11 to the dispensing module 60. The glue cylinder 604 is controlled to move horizontally along the X-axis 601 and Y-axis 602, and the vertical movement cylinder 603 is controlled to drive the glue cylinder 604 to move vertically up and down, applying glue to the upper surface of the lower cover 70.

[0055] like Figure 6 As shown, a dust blowing module 30 is installed on the workbench 10 between the loading / unloading module 20 and the screw locking module 40. The dust blowing module 30 includes a movable air pipe 301 and a pressure block 302 mounted on the support plate 12. The pressure block 302 is vertically movable and positioned above the positioning fixture 111. One end of the air pipe 301 faces the positioning fixture 111, and the other end is connected to an external air source. Before installing the screws 701 and overflow pipe 703, the bottom pipe of the lower cover 70 is dusted. The pressure block 302 is pressed down while the air pipe 301 is pressed against the pipe of the lower cover 70 and blows air to remove dust from the pipe of the lower cover 70.
