Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0027] The embodiments of the present application provide a precise palletizing device for plates, which can solve the problems in the related art that during the palletizing of plates, using multiple cylinders to push the push plate to align the plates will not only increase production costs but also be inconvenient for later debugging and maintenance.

[0028] Please refer to Figures 1-4 , a precise palletizing device for plates, which includes: a workbench 1, a push plate 2, and a centering component 3. There are four groups of the push plates 2, and the four groups of the push plates 2 are evenly distributed in a ring on the workbench 1. The push plate 2 is slidably connected to the workbench 1;

[0029] The centering assembly 3 includes a turntable 31, a rotating column 32, a cylinder 33, four fixed columns 34 and four connecting rods 35. The rotating column 32 is rotatably arranged in the workbench 1. The rotating column 32 is located at the center of the four push plates 2. The turntable 31 is arranged at the upper end of the rotating column 32. The four fixed columns 34 are evenly arranged in a ring at the upper end of the turntable 31. One ends of the four connecting rods 35 are respectively hinged to the four push plates 2. The ends of the connecting rods 35 far from the push plates 2 are sleeved on the fixed columns 34 and rotatably connected thereto. Both ends of the cylinder 33 are respectively hinged to the rotating column 32 and the workbench 1;

[0030] In this way, when it is necessary to stack the plates, the plates can be placed on the workbench 1 so that the plates are located between the four push plates 2. Then the cylinder 33 is started to extend and expand. In this way, the cylinder 33 will push the rotating column 32 to rotate, thereby driving the four fixed columns 34 on the turntable 31 to rotate. When the fixed columns 34 rotate, they will drive the push plates 2 to move through the connecting rods 35. At the same time, due to the limiting effect of the sliding connection between the push plates 2 and the workbench 1, the connecting rods 35 will pull the four push plates 2 to approach each other, so as to respectively abut against the four sides of the plates through the four push plates 2 and push the plates to move to keep them in the centered position;

[0031] After aligning the plates, the cylinder 33 can be contracted and reset, thereby driving the rotating column 32 to reverse and making the four fixed columns 34 on the turntable 31 rotate in the reverse direction. In this way, the push plates 2 can be pushed to move away from each other through the connecting rods 35 to reset the push plates 2, so as to increase the space between the push plates 2 to facilitate the stacking of the next plate;

[0032] Then the next plate can be placed on the plate on the workbench 1. By extending the cylinder 33 to make the push plates 2 approach each other and push the plates to move, multiple plates can be accurately stacked together, and the push plates 2 will move away and reset after aligning the plates. In this way, by repeating this process, the plates can be continuously leveled and aligned during the stacking process of the plates, so as to facilitate the transportation and storage of the plates;

[0033] At the same time, only one cylinder 33 is needed for this device to drive the four push plates 2 to move simultaneously. This not only saves the driving source and reduces the production cost, but also only one cylinder 33 needs to be repaired during maintenance, which can reduce the debugging and maintenance costs and has strong practicability.

[0034] Please refer to Figures 3-4, a plurality of sliding grooves 11 are formed in the workbench 1. The pushing plate 2 includes a pushing plate body 21, a sliding plate 22, an adjusting component 23 and two groups of guiding plates 24. The sliding plate 22 is arranged in the workbench 1 and is rotatably connected to the connecting rod 35. The two groups of guiding plates 24 are respectively arranged on both sides of the sliding plate 22. The guiding plate 24 is located in the sliding groove 11 and is slidably connected thereto. The pushing plate body 21 is slidably arranged in the sliding plate 22. The adjusting component 23 is arranged in the sliding plate 22 and is connected to the pushing plate body 21 to drive the pushing plate body 21 to approach or move away from the turntable 31;

[0035] In this way, through the limiting effect of the sliding connection between the guiding plate 24 and the sliding groove 11, the moving direction of the sliding plate 22 can be guided, so that the pushing plate body 21 can move linearly, thereby avoiding the deviation of the pushing plate body 21 during the reciprocating movement and affecting the alignment effect of the plates;

[0036] At the same time, during use, the adjusting component 23 can be used to drive the pushing plate body 21 to slide in the sliding plate 22, approaching or moving away from the turntable 31. In this way, the distance between the pushing plate body 21 and the turntable 31 can be adjusted, so as to adjust the positions of the four groups of pushing plate bodies 21. In this way, according to production needs, the distance between the four groups of pushing plate bodies 21 can be adjusted, so that the device can stack and align plates of different sizes, enhancing the applicability of the device and facilitating use.

[0037] Specifically, in this embodiment, the adjusting component 23 includes a threaded rod 231 and a handwheel 232. The threaded rod 231 is rotatably arranged in the sliding plate 22. The threaded rod 231 penetrates through the pushing plate body 21 and is threadedly connected thereto. The handwheel 232 is arranged at one end of the threaded rod 231 away from the turntable 31;

[0038] In this way, when it is necessary to adjust the position of the pushing plate body 21, the staff can rotate the handwheel 232 to drive the threaded rod 231 to rotate through the handwheel 232, so that the threaded rod 231 drives the pushing plate body 21 to move through the threaded connection with the pushing plate body 21. In this way, the staff only needs to rotate the handwheel 232 forward and backward to adjust the position of the pushing plate body 21, which facilitates the on-site operation of the staff and facilitates use;

[0039] At the same time, due to the self-locking property of the threaded transmission of the threaded rod 231, the pushing plate body 21 can be prevented from moving by itself during use, so as to ensure the stability of the device and strong practicability.

[0040] More specifically, a groove 25 is formed at the upper end of the sliding plate 22. The push plate body 21 includes a fitting block 211, a fixing plate 212, a pressing plate 213, and a plurality of elastic members 214. The fitting block 211 is slidably disposed in the groove 25. The fitting block 211 is sleeved on the threaded rod 231 and is threadedly connected thereto. The fixing plate 212 is disposed at the upper end of the fitting block 211. The pressing plate 213 is disposed on the side of the fixing plate 212 close to the turntable 31;

[0041] The elastic member 214 includes a limit post 2141, a limit block 2142, and a spring 2143. The limit post 2141 penetrates through the fixing plate 212 and is slidably connected thereto. One end of the limit post 2141 is fixedly connected to the pressing plate 213. The spring 2143 is sleeved on the limit post 2141. The spring 2143 is located between the fixing plate 212 and the pressing plate 213. The limit block 2142 is disposed on the limit post 2141. The limit block 2142 is located on the side of the fixing plate 212 away from the pressing plate 213;

[0042] In this way, when the staff rotates the threaded rod 231 through the handwheel 232, the threaded rod 231 will push the fixing plate 212 to move through the threaded connection with the fitting block 211, so as to adjust the position of the fixing plate 212;

[0043] When the air cylinder 33 starts to extend and drives the sliding plate 22 to move, the fixing plate 212 will move along with the sliding plate 22. In this way, the fixing plate 212 will push the pressing plate 213 to move through the limit post 2141 and the spring 2143, so that the pressing plate 213 contacts the side surface of the plate. In this way, when aligning the plate through the pressing plate 213, the pressing plate 213 will squeeze the spring 2143, so as to buffer the force of the pressing plate 213 squeezing the plate through the elastic force of the spring 2143, and avoid the fixing plate 212 directly contacting the plate rigidly and causing extrusion damage to the side of the plate. In this way, it can be ensured that the device can align the plate without damaging the plate, and the practicability is strong.

[0044] Wherein, a rubber pad is provided on the side of the pressing plate 213 away from the fixing plate 212;

[0045] In this way, when the pressing plate 213 squeezes the plate, the rubber pad can further enhance the protection effect on the plate, so as to ensure the quality of the plate and facilitate the use.

[0046] Preferably, a plurality of convex blocks 4 are provided at the top of the workbench 1;

[0047] In this way, after the plates are stacked on the workbench 1, the plates can be separated from the workbench 1. When it is necessary to transfer the plates, the fork of the forklift can be inserted into the gap between the convex blocks 4, so as to facilitate lifting the stacked plates by the forklift for transfer, which is convenient for use.
