The robot arm 411 and the robot arm transverse beam 413 are horizontally disposed and perpendicular to each other. The arm translation plate 412 is mounted on the arm transverse beam 413 by an arm transverse translation mechanism such that the arm translation plate 412 can translate along the arm transverse beam 413. The mechanical arm 411 is mounted on the mechanical arm translation plate 412 through a mechanical arm longitudinal translation mechanism, so that the mechanical arm 411 can longitudinally expand and contract along the mechanical arm 411. Thereby enabling the robotic arm 411 to be translatable laterally and retractable longitudinally. As shown in fig. 1 and 5, two round-nose riveting mechanisms 416 constitute a double round-nose riveting mechanism group, and are mounted on the front end of the mechanical arm 411 by a riveting mechanism mounting plate 415. The two fillet riveting mechanisms 416 are symmetrical with the longitudinal central axis of the mechanical arm 411, and respectively form an angle of 45 degrees with the mechanical arm 411.
In this embodiment, the specific structure of the mechanical arm mechanism is shown in fig. 1, 2, 3, and 4. The mechanical arm transverse translation mechanism comprises a mechanical arm transverse guide rail mechanism and a mechanical arm transverse driving mechanism. The robot lateral rail mechanism includes a robot lateral top rail 4131 and a robot lateral side rail 4132. The arm transverse drive mechanism includes an arm transverse rack 4133, an arm transverse drive gear 4134, and an arm transverse motor 4135. The arm transverse top slide 4131, the arm transverse side slide 4132, and the arm transverse rack 4133 are all disposed along the orientation of the arm transverse beam 413 and are disposed horizontally. The arm transverse top slide 4131 and the arm transverse rack 4133 are located on the top surface of the arm transverse beam 413. The arm transverse side rails 4132 are located on the sides of the arm transverse beam 413. The arm translation plate 412 is horizontally disposed, with the bottom being mounted on the arm lateral top slide 4131 by the arm lateral top slide 4121 and on the arm lateral side slide 4132 by the arm lateral side slide 4122.

The arm transverse drive gear 4134 is mounted below the arm translation plate 412, engages the arm transverse rack 4133, and is coupled to the arm transverse motor 4135. Thus, the mechanical arm transverse motor 4135 drives the mechanical arm transverse driving gear 4134 to rotate, and drives the mechanical arm translation plate 412 to translate transversely along the mechanical arm transverse top sliding rail 4131 and the mechanical arm transverse side sliding rail 4132 through the meshing action between the mechanical arm transverse driving gear 4134 and the mechanical arm transverse rack 4133.

The arm longitudinal motor 4116 is mounted below the arm translation plate 412 and is connected to the arm longitudinal drive gear 4115. Therefore, the mechanical arm longitudinal motor 4116 drives the mechanical arm longitudinal driving gear 4115 to rotate, and drives the mechanical arm 411 to extend and retract in the longitudinal direction through the meshing action between the mechanical arm longitudinal driving gear 4115 and the mechanical arm longitudinal rack 4114. In order to prevent the mechanical arm 411 from moving out of the mechanical arm translation plate 412, two ends of the mechanical arm 411 are provided with longitudinal limiting blocks 4117. In addition, in the present embodiment, the mechanical arm longitudinal rack 4114 is an oblique rack; the arm longitudinal drive gear 4115 is an oblique tooth gear.

The rounded translating carriage 431 is mounted to the frame base 424 of the rounded riveting frame by means of a slide 435 and a slide 434 and is capable of horizontal movement along the slide 434. A horizontal fillet hemming die strip 432 is installed at the front end of the fillet translating frame 431. The round horizontal cylinder 433 is mounted on the frame back plate 423 of the round riveting frame, and the piston of the round horizontal cylinder is connected with the rear end of the round translation frame 431. The front end face of the horizontal fillet flanging die strip 432 is provided with a die groove with a circular arc horizontal section.
The fillet platen hemming mechanism comprises a fillet vertical cylinder 441, a fillet die bar lifting frame 442, a fillet platen 443 and a vertical fillet hemming die bar 444. The round angle die bar lifting frame 442 is mounted below the frame top plate 422 of the round angle riveting frame through a guide post and guide sleeve mechanism 4421. A rounded vertical cylinder 441 is mounted above the frame top plate 422 with its piston connected to a rounded die bar lifter 442. The radius presser 443 is mounted below the radius bar frame 442 by a spring post mechanism 4431. A vertical fillet hemming die strip 444 is fixed under the fillet die strip lifter 442. The front end face of the vertical fillet flanging die strip 444 is provided with a die groove with a circular arc horizontal section. A clamping protrusion with a circular arc horizontal section is arranged at the rear of the round angle pressing plate 443. The corner presser piece 443 is engaged by engagement with a die groove on the front end surface of the vertical corner crimping die 444, and is movable in the vertical direction with respect to the vertical corner crimping die 444.
The die cavity on the front end surface of the horizontal fillet folding die strip 432 is the same as the die cavity on the front end surface of the vertical fillet folding die strip 444 in specification and is matched with the circular arc of the bottom plate fillet of the refrigerator liner.
The working principle of the fillet riveting mechanism of the embodiment is shown in fig. 8, 9 and 10. In fig. 8, 9 and 10, 3901 is a bottom plate, and a generally Z-shaped bottom plate may also be a flat plate bottom plate, 4903 is a bottom plate fillet folded edge, 3902 is a coaming, that is, a large and small U-shaped coaming or a port-shaped coaming, 4904 is a coaming fillet folded edge, and 1901 is an arc angle supporting block on the liner supporting mechanism. The bottom plate fillet bent edge 4903 and the coaming fillet bent edge 4904 are both 90-degree bends at the fillet. Bottom plate 3901 is perpendicular to shroud 3902. When the refrigerator liner is placed on the liner supporting mechanism, the structure is shown in figure 8. Then, the fillet caulking mechanism 416 performs caulking by moving the mechanical arm 411 laterally and moving it longitudinally to the fillet bending position. The riveting process is as follows: first, the round vertical cylinder 441 drives the round bar lifter 442 to press down, and when the round bar presser piece 443 is pressed against the round bar support block 1901, the round bar lifter 442 stops descending. At this time, the bottom surface of the vertical round-corner crimping die 444 is flush with the bottom surface of the round-corner crimping die 443. Then, the round horizontal cylinder 433 drives the horizontal round hemming die 432 to press forward so that the bottom plate round bending edge 4903 is bent inward, so that the edge portion of the bottom plate 3901, the coaming round bending edge 4904, and the bottom plate round bending edge 4903 are overlapped to form a three-layer edge structure 4905 as shown in fig. 9. Thereafter, the rounded horizontal cylinder 433 drives the horizontal rounded hemming die strip 432 to retract to the vertical rounded hemming die strip 444. Then, the round vertical cylinder 441 continues to drive the round bar lifting frame 442 to press down, at this time, the round bar pressing plate 443 presses on the round bar supporting block 1901, and the vertical round bar folding die 444 continues to press down, so as to bend the three-layer edge structure 4905 downward, forming a corner four-layer riveting structure 4906 as shown in fig. 10, and completing the riveting.
In addition, when the riveting mechanism for riveting the bottom plate fillet of the refrigerator liner is used for riveting, the erection direction of the transverse beam 413 of the mechanical arm is parallel to the end edge of the refrigerator liner. The end edge of the refrigerator liner corresponds to two fillets. The two round corner riveting mechanisms 416 on the mechanical arm 411 correspond to the two round corners respectively, and rivet the two round corners respectively. The right round angle is riveted by the round angle riveting mechanism 416 on the left side of the arm 411, and the left round angle is riveted by the round angle riveting mechanism 416 on the right side of the arm 411. When riveting of the right side fillet is completed, the left side fillet needs to be riveted, and the mechanical arm 411 needs to translate along the mechanical arm transverse beam 413.
In addition, in this embodiment, in order to take into account the difference in height of the refrigerator liners of different models, the height of the fillet riveting mechanism is required to be adjustable. To this end, the robot transverse beam 413 is mounted on the robot support column 4140 by a robot lifting mechanism. The robot support column 4140 is vertically mounted on the station base 400. As shown in fig. 1 and 2, the arm lifting mechanism includes an arm lifting link 4141, an arm lifting slide 4142, an arm lifting motor 4143, an arm lifting synchronizing shaft 4145, and an arm lifting rack 4147. The number of the mechanical arm lifting connecting frames 4141 is two. The two arm lifting connection frames 4141 are at the same height and are respectively erected on the two arm support columns 4140 through the vertically arranged arm lifting sliding rails 4142. The two ends of the mechanical arm lifting synchronizing shaft 4145 are respectively erected on the mechanical arm lifting connecting frame 4141, and the middle part of the mechanical arm lifting synchronizing shaft is connected with the mechanical arm lifting motor 4143 through a speed reducer 4144. The mechanical arm lifting racks 4147 are two. The two mechanical arm lifting racks 4147 are respectively and vertically arranged on the two mechanical arm support columns 4140 and are positioned on the inner sides of the mechanical arm lifting slide rails 4142. The arm lifting synchronizing shaft 4145 is provided with arm lifting gears 4146 at both ends thereof, which are engaged with the arm lifting racks 4147. The arm lifting gear 4146 can rotate in synchronization with the arm lifting synchronizing shaft 4145. The two ends of the mechanical arm transverse beam 413 are mounted on the mechanical arm lifting connecting frame 4141. Therefore, when the mechanical arm lifting motor 4143 drives the mechanical arm lifting synchronizing shaft 4145 to rotate, the two mechanical arm lifting gears 4146 at two ends of the mechanical arm lifting synchronizing shaft 4145 synchronously rotate, and the mechanical arm lifting connecting frame 4141, the mechanical arm lifting motor 4143 and the mechanical arm lifting synchronizing shaft 4145 are driven to synchronously lift by the meshing action between the mechanical arm lifting gears 4146 and the mechanical arm lifting racks 4147, so that the mechanical arm transverse beam 413 is driven to lift.
