[0031] Embodiments

[0032] In order to solve the problem that the existing nail pressing equipment for pressing nails on new energy charging guns has low working efficiency and cannot adapt to the needs of enterprise development when in use, with reference to Figures 1-6 The present application discloses a nail pressing and assembling equipment, which comprises a loading table 10, a step-moving material mechanism 20, a rivet feeding mechanism 30, a pressing and covering mechanism 40 and a plurality of bearing jigs 50.

[0033] The step-moving material mechanism comprises a bearing table 21 arranged on the loading table along a first direction, two first Z-axis driving assemblies 22 arranged on the bottom of the loading table on both sides of a second direction, two first X-axis driving assemblies 23 arranged on both sides of the second direction above the loading table and connected with the two first Z-axis driving assemblies respectively, and two lifting plates 24 connected oppositely on the driving parts of the two first X-axis driving assemblies.

[0034] The plurality of bearing jigs are arranged on the bearing table, and a lower profiling groove 51 for placing a product lower shell is arranged on each of the plurality of bearing jigs.

[0035] The rivet feeding mechanism comprises two portal frames 31 arranged above the step-moving material mechanism along a second direction, two Y-axis driving assemblies 32 arranged above the cross beams of the two portal frames respectively, a second X-axis driving assembly 33 connected above the two Y-axis driving assemblies, a second Z-axis driving assembly 34 connected on the driving part of the second X-axis driving assembly, a rivet feeding assembly 35 connected on the driving part of the second Z-axis driving assembly for placing two rivets on the product lower shell, three rivet feeders 36 arranged on the bearing table on one side of the second direction of the step-moving material mechanism (the feeders are known technology, and will not be described in detail herein), and a rivet taking assembly 37 arranged between the three rivet feeders and the step-moving material mechanism for grabbing and placing the rivets in the three rivet feeders to the rivet feeding assembly.

[0036] The pressing mechanism comprises a reverse L-shaped support plate 41 arranged above the stepping material moving mechanism on the carrier table, a third Z-axis driving assembly 42 arranged above the transverse part of the reverse L-shaped support plate, a rivet pressing plate 43 arranged below the transverse part of the reverse L-shaped support plate and connected with the third Z-axis driving assembly, a profiling pressing block 44 arranged at the bottom of the rivet pressing plate, and an upper profiling groove 441 arranged at the bottom of the profiling pressing block and used for pressing the upper shell of the product.

[0037] Based on the above structure, the operator places the lower shell of the product on the carrier jig at the loading station and places the carrier jig on the carrier table. When the two first Z-axis driving assemblies drive the two first X-axis driving assemblies to rise, the carrier jig can be lifted. When the two first X-axis driving assemblies drive the two lifting plates to move backward and the two first Z-axis driving assemblies drive the two first X-axis driving assemblies to reset, the carrier jigs can be shifted backward. When the carrier jigs are located at the rivet loading mechanism, the three rivet taking assemblies first suck three rivets from the three rivet feeders. Then, the two Y-axis driving assemblies drive the second X-axis driving assembly to move so that the rivet loading assembly is located below the three rivet taking assemblies. After that, the three rivet taking assemblies place the sucked rivets in the rivet loading assembly. After the action is completed, the two Y-axis driving assemblies drive the second X-axis driving assembly to move to the upper side of the lower shell of the product. The second X-axis driving assembly continuously adjusts the position of the rivet loading assembly and places three rivets in the lower shell of the product (the rivet loading mechanism needs to load twice, and a total of six rivets need to be sucked). When the six rivets are loaded on the lower shell of the product and located at the pressing mechanism, the operator loads the upper shell of the product on the lower shell. After the action is completed, the third Z-axis driving assembly drives the rivet pressing plate to descend, so that the lower shell of the product and the upper shell of the product are riveted.

[0038] In order to realize the positioning of the carrier table, a plurality of positioning assemblies 25 are arranged in a straight line array above the carrier table. Each positioning assembly comprises four positioning columns 251. Four positioning holes 53 are arranged at the bottom of the carrier jig corresponding to the four positioning columns. In the specific implementation process, after the carrier jig is shifted by the stepping material moving mechanism each time, the four positioning holes of the carrier jig are inserted with the four positioning columns of each positioning assembly.

[0039] In addition to the above structure, the second direction of the carrier jig is provided with a lap block 52 on each side. A plurality of corresponding lap grooves 241 are arranged above the two lifting plates. In this way, the lifting plates can avoid the situation that the carrier jig slips during the shifting of the carrier jig, and have strong practicability in use.

[0040] In some preferred embodiments, the first Z-axis drive assembly of the present application comprises two electric cylinders arranged separately on the bottom of the platform, the first X-axis drive assembly, the second X-axis drive assembly, the Y-axis drive assembly and the second Z-axis drive assembly are all servo-screw modules, and the third drive assembly is a hydraulic cylinder.

[0041] In one specific embodiment, the rivet taking assembly of the present application comprises a cylinder a 371 arranged on the platform, a T-shaped plate 372 arranged on the piston rod of the cylinder a, and an electromagnetic suction head 373 arranged at the bottom end of the vertical part of the T-shaped plate. When taking the rivet from the rivet feeder, the cylinder a drives the T-shaped plate to descend, and the electromagnetic suction head takes a rivet from the rivet feeder.

[0042] In one specific embodiment, the rivet loading assembly of the present application comprises a sliding plate 351 connected to the driving part of the second Z-axis drive assembly, a loading plate 352 vertically arranged on the sliding plate, three cylinders b 353 arranged above the loading plate, three pressing pins 354 arranged below the loading plate and connected to the piston rods of the three cylinders b respectively, three pneumatic telescopic slides 355 arranged on the sliding plate below the loading plate, three pneumatic lifting slides 356 connected to the three pneumatic telescopic slides respectively, and three material receiving duckbills 357 arranged on the three pneumatic lifting slides respectively and corresponding to the three pressing pins. In the specific implementation, the two Y-axis drive assemblies drive the second X-axis drive assembly to move to the designated position. At this time, the three pneumatic lifting slides drive the three material receiving duckbills to descend, and the three pneumatic telescopic slides drive the three pneumatic lifting slides to extend so that the three material receiving duckbills are below the three electromagnetic suction heads. When the three electromagnetic suction heads stop adsorbing the rivets, the three rivets will be lowered into the three material receiving pins. After this step is completed, the two Y-axis drive assemblies drive the second X-axis drive assembly to move until the three material receiving duckbills are above the product lower shell, and the position of the sliding plate is continuously adjusted by the second X-axis drive assembly. In this process, the three cylinders b drive the pressing pins to descend to press the rivets from the material receiving duckbills to the product lower shell.

[0043] In one preferred embodiment, the present application is provided with guide sleeves (not labeled) around the inside of the inverted L-shaped support plate, guide columns 431 are provided around the top of the rivet pressing top plate and pass through the guide sleeves, limit nuts 4311 are arranged at the top of the guide columns, springs 432 are arranged around the guide columns between the limit nuts and the rivet pressing top plate. When the third Z-axis drive assembly drives the rivet pressing top plate to descend, the profiled pressing block can flexibly press and cover the product upper shell and the product lower shell, avoiding damage to them.
