DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] A pallet rapid assembly and stacking device, please refer to Figure 2-8 , including a lifting frame 11 and a bracket 2. The lifting frame 11 is used to drive the bracket 2 to rise and fall in the vertical direction. Specifically, the bracket 2 can be lifted and lowered in the vertical direction by sprocket drive, cylinder 310 lifting or screw drive, so that the tray can be moved up and down.

[0029] It also includes a claw assembly 3, which includes at least a back plate 301 and two claw arms 302 connected to the front side of the back plate 301, wherein a motor 4 is fixed on the back side of the bracket 2, and the output end of the motor 4 is fixedly connected to the first gear 5. The surface of the bracket 2 is opened and rotatably connected to a rotating shaft 7, one end of the rotating shaft 7 is coaxially fixedly connected to the second gear 6, and the other end extends to the front side of the bracket 2 and is fixedly connected to the back plate 301, the first gear 5 and the second gear 6 are meshed and connected, the motor 4 can rotate the first gear 5, and the first gear 5 drives the second gear 6 and the rotating shaft 7 to rotate, thereby enabling the claw assembly 3 to rotate relative to the bracket 2 as a whole.

[0030] The two claw arms 302 can move in opposite directions to approach or move away from each other. Specifically, a connecting plate 305 is fixedly connected to the front side of the back plate 301 through a connecting rod 316, and two parallel slide rails 306 are fixedly connected to the upper and lower sides of the connecting plate 305 respectively. Slide racks 307 are slidably connected to the two sides of the two slide rails 306 respectively, and the adjacent ends of the two slide rails 306 are fixedly connected to racks 308. A transmission gear 309 is rotatably connected to the front side of the connecting plate 305, and the transmission gear 309 is meshed with the two racks 308. The two claw arms 302 are respectively fixed to the ends of the two slide racks 307 that are away from each other; a cylinder 310 is fixedly connected between the back plate 301 and the connecting plate 305, and a convex plate 312 is fixed on one of the slide racks 307. The telescopic end of the cylinder 310 is fixedly connected to a short plate 311, and the short plate 311 extends to the front side of the connecting plate 305 and is fixedly connected to the convex plate 312. The extension and retraction of the cylinder 310 can drive the convex plate 312 and the slide 307 connected to the convex plate 312 to move along the slide rail 306 through the short plate 311. The slide 307 drives the transmission gear 309 to rotate through the rack 308 connected to it. The transmission gear 309 drives another rack 308 and another slide 307 to move along the slide rail 306, so that the two slides 307 move synchronously in opposite directions. When the cylinder 310 is shortened, the two slides 307 drive the claw arms 302 to move closer to each other. When the cylinder 310 is shortened, the two slides 307 drive the claw arms 302 to move away from each other.

[0031] A strip plate 303 is fixedly connected to the lower edge of the opposite side of the two claw arms 302, and a rubber stripe plate 315 is arranged on the upper surface of the strip plate 303. The pallet is placed on the surface of the rubber stripe plate 315 to reduce deformation or damage of the pallet plate due to uneven force during clamping; a limit baffle 304 is connected to the top of the two claw arms 302, and the limit baffle 304 can be at least partially moved to the top of the opposite side of the two claw arms 302 to limit the movement of the pallet.

[0032] A pushing cylinder 8 is fixed on the side of the bracket 2, a through hole 21 is opened on the front surface of the bracket 2, and a strip groove 3011 is opened on the surface of the back plate 301. The telescopic end of the pushing cylinder 8 passes through the through hole 21 to between the back plate 301 and the bracket 2 and is fixedly connected with a pushing plate 9. When the pushing cylinder 8 is extended, it can drive the pushing plate 9 to pass through the strip groove 3011 to the front side of the back plate, and then push the tray forward from the strip plate 303.

[0033] When in use, the transverse plate and the longitudinal plate of the pallet are arranged according to the pallet structure and placed on the strip plate 303 between the two claw arms 302. The cylinder 310 contracts to drive the two claw arms 302 to move closer to each other. The two claw arms 302 clamp and fix the pallet from both sides, and the limit baffle 304 moves to the top of the pallet, so that the upper and lower sides of the pallet are clamped and limited between the limit baffle 304 and the strip plate 303, respectively, so that the pallet can be stably fixed to avoid sliding or shifting during loading. The lifting frame 11 then drives the claw assembly 3 to move upward as a whole to the processing station for processing. After nailing on the front side, the motor 4 drives the claw assembly 3 to rotate as a whole to change the angle and nail the back side, thereby improving the flexibility of the combined nailing operation, facilitating multi-angle complex processing, changing the processing direction, and processing the back side of the plate; after nailing on both the front and back sides, the cylinder 310 extends to drive the two claw arms 302 to move away from each other, so that the assembled pallet and the claw arms are loosened. At this time, the push cylinder 8 extends to drive the push plate 9 to pass through the strip groove 3011 and abut against the back side of the pallet, thereby pushing the pallet away from the strip plate 303. A conveyor belt can be set above the front side of the device for automatically placing the assembled pallets, or a pallet collection frame can be set at the front side of the processing position of the device. The push plate 9 pushes the pallet away from the strip plate 303 to the conveyor belt or the pallet collection frame located above the front side of the device, so that the integrated operation of the pallet combination is completed synchronously during the transfer from the lower layer of the lifting frame 1 to the upper layer for placement and stacking, thereby improving production efficiency.

[0034] In this embodiment, U-shaped frames 313 are fixedly connected on both sides above the upper slide rail 306, and a section of the limit baffle 304 extends into the U-shaped frame 313 and is rotatably connected to the U-shaped frame 313; a limit pin 314 is fixedly connected above the claw arm 302, and a through groove 3041 is opened on the surface of the limit baffle 304, and the limit pin 314 is slidably connected to the through groove 3041. When the cylinder 310 contracts and drives the slide 307 to slide, the slide 307 simultaneously drives the limit pin 314 to slide, and the limit pin 314 slides relatively in the through groove 3041, so that the limit baffle 304 rotates, and the limit baffle 304 rotates inward to above the pallet, that is, when the cylinder 310 drives the slide 307 and the claw arm 302 to clamp on both sides of the pallet, the limit baffle 304 synchronously rotates until its end is limited above the pallet, and two linkage actions are synchronously completed by a single cylinder 310, so that the left and right sides and the upper and lower sides of the pallet are synchronously clamped and fixed, making the entire equipment compact, reducing hardware costs, simplifying the control system, and realizing the synchronous coordination of the two clamping actions.
