Several pressing block positioning seats 16 are arranged at intervals on the turntable 6. In the present embodiment, the number of the pressing block positioning seats 16 is 4, resulting in 4 workstations, namely, a loading and unloading station, a lining assembly station, an O-ring assembly station and an inspection station.

[0019] The block handling robot arm 3, the lining assembly robot arm 8, the O-ring assembly robot arm 4 and the inspection robot arm 5 are distributed at intervals around the turntable 6, corresponding to the loading and unloading stations, the lining assembly station, the O-ring assembly station and the inspection station.

During the process of the press block on the first mobile conveyor line 22 being transferred to the loading and unloading station by the press block handling robot 3, it passes above the third visual inspection camera 21. The third visual inspection camera 21 is used to inspect the bottom structure of the press block to ensure that the angle of the concave arc surface at the bottom of the press block is consistent. If the angle of the concave arc surface is misaligned, it is corrected by rotating the press block handling robot 3 and then placed in the press block positioning seat of the loading and unloading station to avoid the problem of misalignment in subsequent pressing.

[0022] After the trays 35 on the first mobile conveyor line 22 are emptied, the first elevator 23 is lowered and transferred to the lower conveyor line of the upper tray line 1 to return the empty trays. A second elevator 18 is provided at the front end of the lower tray line 2, and a second mobile conveyor line 15 is provided on the second elevator 18. The upper conveyor line of the lower tray line 2 sends the empty trays to the second mobile conveyor line 15, and the briquette handling robot 3 transfers the assembled briquette 33 to the trays on the second mobile conveyor line 15. After the trays on the second mobile conveyor line 15 are full, the second elevator 18 descends and transfers the trays filled with briquette 33 to the lower conveyor line of the lower tray line 2 for delivery, thereby improving the level of automation.

[0023] like Figure 2 As shown, a cover body 20 is suspended above the first moving conveyor line 22, and a first visual inspection camera 19 pointing downward is arranged on the top of the cover body 20, which can perform visual inspection on the material tray on the first moving conveyor line 22, send a signal to the control system, obtain the number and position information of the briquettes 33 on the material tray, and facilitate the control system to control the handling of the briquette handling robot 3.

An arc groove 30 corresponding to the positioning column 27 is arranged at the end of the positioning plate 29. The positioning plate 29 is driven to move by the second telescopic cylinders 28 on both sides, and the arc groove 30 is used to clamp the two sides of the positioning column 27, so as to achieve accurate positioning of the lining 26. Then the second telescopic cylinder 28 is retracted and reset, which is convenient for subsequent press-fitting.

[0027] like Figure 4As shown, the lining assembly robot 8 includes a horizontal linear module 81, an electric cylinder 82, a pulling pressure sensor 83 and a first pneumatic clamp 84. The electric cylinder 82 is vertically arranged on the horizontal linear module 81, and the electric cylinder 82 is driven by the horizontal linear module 81 to move between the lining material distribution mechanism and the turntable 6. The pulling pressure sensor 83 is arranged at the output end at the bottom of the electric cylinder 82, and the first pneumatic clamp 84 is arranged at the bottom of the pulling pressure sensor 83. Pressure detection during press-fitting is performed to ensure that the pressure is in place but not too high.

[0028] The first pneumatic clamp 84 moves downward to grab the pressure block on the pressure block positioning seat corresponding to the lining assembly station, transfers it to the top of the lining positioning seat 25 and then moves vertically downward to realize the press-fitting of the pressure block and the lining on the lining positioning seat 25. After the press-fitting is completed, the pressure block is returned to the pressure block positioning seat of the lining assembly station along the original route, and the turntable 6 rotates 90° to switch to the O-ring assembly station to facilitate the subsequent assembly of the O-ring.

[0029] The O-ring vibrating plate 13 is arranged on one side of the O-ring assembly robot 4, and the output end of the O-ring vibrating plate 13 is provided with an O-ring output trough 14 extending to the bottom of the O-ring assembly robot 4. In this embodiment, the front end of the O-ring output trough 14 is provided with an O-ring distributing mechanism, such as Figure 5 As shown, the O-ring dispensing mechanism includes an O-ring holder 31 and a second telescopic cylinder 12 (as shown in FIG. 1 ) that pushes the O-ring holder 31 to move horizontally in a direction perpendicular to the O-ring output trough. Figure 1 As shown in the figure, the O-ring holder 31 is driven by the telescopic movement of the second telescopic cylinder 12 to move horizontally in a direction perpendicular to the O-ring output trough 14, and a single O-ring is introduced into the O-ring holder 31 to achieve dislocation material distribution. The O-ring assembly robot 4 picks up the O-ring 32 in the O-ring holder 31 and transfers it to the outer circle of the pressing block 33 to achieve the assembly of the O-ring. In this embodiment, the O-ring needs to be assembled twice, and the two O-rings are assembled on the pressing block 33 respectively.

[0030] A pressure block detection positioning seat 7 located in front of the detection robot 5 and a third telescopic cylinder 9 for driving the pressure block detection positioning seat 7 to move radially along the turntable 6 are arranged above the turntable 6. The position height of the pressure block detection positioning seat 7 is higher than the position height of the pressure block positioning seat 16, and they do not affect each other, and the pressure block detection positioning seat 7 does not rotate with the turntable 6.

[0031] like Figure 5The detection robot 5 includes a vertical linear module 51 and a second pneumatic clamp 52. The second pneumatic clamp 52 is horizontally arranged on the vertical linear module 51 and points to the pressure block detection positioning seat 7. The second pneumatic clamp 52 grabs the pressure block on the pressure block positioning seat in the corresponding area of ​​the detection station and then rises to a certain height. The third telescopic cylinder 9 drives the pressure block detection positioning seat 7 to move to the bottom of the second pneumatic clamp 52. After the second pneumatic clamp 52 releases the pressure block, the pressure block falls onto the pressure block detection positioning seat 7, and then the second pneumatic clamp 52 continues to rise to avoid affecting the detection.

[0032] A second visual inspection camera 17 pointing horizontally toward the pressing block inspection and positioning seat 7 is provided on one side of the pressing block inspection and positioning seat 7. The O-ring and lining on the pressing block are inspected by the second visual inspection camera 17 to avoid problems of missing or wrong installation.

[0033] After the inspection, the compressed block is returned to the compressed block positioning seat below through the inspection robot 5, and the turntable 6 rotates 90° to switch to the loading and unloading station. The qualified compressed blocks detected by the second visual inspection camera 17 are sent to the unloading tray line body 2 through the compressed block handling robot arm 3.
