DETAILED DESCRIPTION

[0017] The present application will be further described below in conjunction with specific examples. The illustrative examples of the present application and the description are used to explain the present application, but are not intended to limit the present application.

[0018] Example 1, a kind of dispensing metal can bottom panel stacking device of this embodiment, as shown in Figures 1-5 shown, including mounting frame 11, electric control lifting slider 12, shading cylinder 13, fixed plate 21, electric control push rod 22, single slider 23, arc-shaped clamping plate 24, torsion spring 25, rubber sheet 26, gas pipeline 27 and gas flow heater 3; the electric control lifting slider 12 is slidably connected on the mounting frame 11; the electric control lifting slider 12 is fixedly connected with the shading cylinder 13; the four sides of the shading cylinder 13 are each slidably connected with a fixed plate 21; the four sides of the shading cylinder 13 are each provided with two electric control push rods 22, and the two electric control push rods 22 are respectively located on the two sides of the corresponding fixed plate 21; the telescopic end of each electric control push rod 22 is fixedly connected with the corresponding fixed plate 21; a plurality of single sliders 23 are equidistantly fixedly connected on each fixed plate 21; all single sliders 23 are slidably connected with the shading cylinder 13; each single slider 23 is rotatably connected with an arc-shaped clamping plate 24 on the inside of the shading cylinder 13; two torsion springs 25 are fixedly connected between each arc-shaped clamping plate 24 and the corresponding single slider 23; each arc-shaped clamping plate 24 is made of a metal material with high heat transfer efficiency; each arc-shaped clamping plate 24 is fixedly connected with a rubber sheet 26 at the bottom to prevent scratching the panel body 7; the shading cylinder 13 is fixedly connected with the gas pipeline 27; the gas pipeline 27 is connected with a suction device; each arc-shaped clamping plate 24 in the bottom first layer is provided with a hollow cavity structure; each arc-shaped clamping plate 24 in the bottom first layer is provided with an air nozzle structure 2401 communicating with the hollow cavity structure; the air nozzle structure 2401 of each arc-shaped clamping plate 24 in the bottom first layer communicates with the gas pipeline 27; a plurality of punching hole structures 2402 are formed on each arc-shaped clamping plate 24 in the bottom first layer; the shading cylinder 13 is provided with a gas flow heater 3; the gas inlet end of the gas flow heater 3 is connected with an inert gas flow conveying device; a plurality of jet hole structures 301 are formed on the gas outlet end of the gas flow heater 3.

[0019] AsFigure 2 and Figure 3 As shown in the figure, the light shielding cylinder 13 is equipped with a cover plate 4 for covering the top of the first panel body 7; the upper surface of the cover plate 4 is provided with a tapered flow guide structure that can guide the hot air flow blown out of the air jet hole structure 301 to flow towards the inner wall of the light shielding cylinder 13.

[0020] In this embodiment, the external conveyor bed sequentially conveys the panel body 7 that has completed the dispensing process to the position below the light shielding cylinder 13, and the outer surface of the panel body 7 is provided with a downwardly tapered inverted conical structure; when the external conveyor bed conveys the first panel body 7 to the position below the light shielding cylinder 13, the operator timely covers the cover plate 4 on the first panel body 7, and the electric control lifting slide 12 drives the light shielding cylinder 13 to move downwardly to cover the first panel body 7; in this process, when the first layer of arc-shaped clamping plates 24 contact the upper surface of the first panel body 7, the first layer of arc-shaped clamping plates 24 are flipped upwardly due to the obstruction of the upper surface of the first panel body 7, and the first layer of arc-shaped clamping plates 24 drive the torsion springs 25 to twist; when the first layer of arc-shaped clamping plates 24 are aligned with the middle part of the first panel body 7, the torsion springs 25 drive the first layer of arc-shaped clamping plates 24 to flip downwardly and reset, so that the middle part of the first panel body 7 is clamped between the four arc-shaped clamping plates 24 in the first layer; then the electric control lifting slide 12 drives the light shielding cylinder 13 to move upwardly, and the light shielding cylinder 13 drives the panel body 7 clamped in the first layer of arc-shaped clamping plates 24 to move upwardly.

[0021] When the external conveyor bed transports the second panel body 7 under the light shielding cylinder 13, the electric control lifting slider 12 drives the light shielding cylinder 13 to move downwards to cover the second panel body 7, in the process, when the first layer of arc-shaped clamping plates 24 from bottom to top contact the upper surface of the second panel body 7, the first panel body 7 is stacked on the second panel body 7, and the first layer of arc-shaped clamping plates 24 is blocked by the upper surface of the second panel body 7 and is turned up, at the same time, the first layer of arc-shaped clamping plates 24 drives the torsion spring 25 to twist, and the second layer of arc-shaped clamping plates 24 is blocked by the upper surface of the first panel body 7 and is turned up, at the same time, the second layer of arc-shaped clamping plates 24 drives the torsion spring 25 to twist, when the first layer of arc-shaped clamping plates 24 is aligned with the middle shrinkage area of the second panel body 7, the twisted torsion spring 25 drives the second layer of arc-shaped clamping plates 24 to turn down and reset, at the same time, when the second layer of arc-shaped clamping plates 24 is aligned with the middle shrinkage area of the first panel body 7, the twisted torsion spring 25 drives the second layer of arc-shaped clamping plates 24 to turn down and reset, so that the middle of the first panel body 7 is clamped between the four arc-shaped clamping plates 24 in the second layer, and the middle of the second panel body 7 is clamped between the four arc-shaped clamping plates 24 in the first layer, then the electric control lifting slider 12 drives the light shielding cylinder 13 to move upwards, and the light shielding cylinder 13 drives the two panel bodies 7 clamped in the first layer of arc-shaped clamping plates 24 and the second layer of arc-shaped clamping plates 24 respectively to rise upwards.

[0022] Then, the layer-by-layer stacking work of each panel body 7 is carried out in the above-mentioned steps, after the layer-by-layer stacking work of each panel body 7 in this batch is completed, the operator only needs to temporarily stop the external conveyor bed, and controls each electric control push rod 22 to push the single slider 23 connected thereto to move away from the light shielding cylinder 13, at the same time, the single slider 23 drives the arc-shaped clamping plate 24 connected thereto to move away from the panel body 7, so that the stacked panel body 7 is separated from the clamping of the arc-shaped clamping plate 24, falls from the light shielding cylinder 13, and completes a step of unloading the stacked panel body 7.

[0023] In the embodiment, during the layer-by-layer stacking process of the panel body 7, the light shielding cylinder 13 can shield the glue layer in the panel body 7 from external light, and the external inert gas conveying device continuously conveys inert gas into the gas flow heater 3, while the gas flow heater 3 continuously heats the inert gas into hot gas, which is continuously sprayed into the light shielding cylinder 13 through the jet hole structure 301 to heat and keep warm the arc-shaped clamping plate 24 and the panel body 7 in the light shielding cylinder 13. Since the uppermost panel body 7 is covered with the cover plate 4, the hot gas is partially flowed into the light shielding cylinder 13 through the conical flow guide surface of the cover plate 4, and the arc-shaped clamping plate 24 can efficiently transfer more heat to the panel body 7 clamped and held thereby, so that the panel body 7 has better heating and keeping warm effect, thus ensuring that neither light nor temperature can affect the glue layer in the panel body 7.

[0024] Whenever the electrically controlled lifting slider 12 drives the light shielding cylinder 13 to move downward above the panel body 7 below, the first layer of arc-shaped clamping plate 24 tightly abuts the upper surface of the panel body 7 below, while the external suction device performs suction work on the hollow cavity structure of the first layer of arc-shaped clamping plate 24 through the gas conveying pipeline 27, so that most of the air in the panel body 7 below is sucked away through the suction hole structure 2402 of the arc-shaped clamping plate 24. In this way, the residual amount of air in the panel body 7 can be reduced, not only reducing the oxidation effect of the residual air in the panel body 7 on the internal glue layer, but also improving the lamination effect of the panel body 7 stacked together with the panel body 7 above, preventing external air from entering the panel body 7 and contacting the glue layer, and effectively ensuring that the glue layer always maintains excellent bonding performance before subsequent packaging work.

[0025] In Embodiment 2, based on Embodiment 1 described above, as Figures 1-6As shown, the metal can bottom panel stacking device after dispensing of the embodiment is slidably connected with the fixed rod 5 in the light shielding cylinder 13; the cover plate 4 is made of ferromagnetic metal material, and the lower end of the fixed rod 5 is provided with a permanent magnet for adsorbing the cover plate 4 made of ferromagnetic material; the lower end of the fixed rod 5 is provided with an insertion block structure 501; the surface of the cover plate 4 is provided with an insertion hole structure 401 adapted to the insertion block structure 501; the fixed rod 5 is provided with a scale ring 502 indicating the stacking number of the panel body 7; in the embodiment, the operator does not need to manually place the cover plate 4 on the first panel body 7, but manually pushes the fixed rod 5 to move downward along the light shielding cylinder 13 until the insertion block structure 501 of the fixed rod 5 is inserted downward on the insertion hole structure 401 of the cover plate 4, the permanent magnet of the fixed rod 5 adsorbs the cover plate 4 firmly, and the height of the cover plate 4 is aligned with the height of the arc-shaped clamping plate 24 of the first layer on the lower side, at this time, most of the scale ring 502 of the fixed rod 5 is located inside the light shielding cylinder 13, only the first scale ring 502 on the upper side of the fixed rod 5 is exposed on the upper side of the light shielding cylinder 13, which indicates that the cover plate 4 is aligned with the arc-shaped clamping plate 24 of the first layer on the lower side at this time, then during the stacking of the first panel body 7, when the first panel body 7 is clamped in the arc-shaped clamping plate 24 of the first layer on the lower side, the cover plate 4 will be automatically covered on the first panel body 7, then during the stacking of the second panel body 7, when the first panel body 7 is pushed up and clamped in the arc-shaped clamping plate 24 of the second layer on the lower side, the cover plate 4 will be pushed up by the first panel body 7 to align with the arc-shaped clamping plate 24 of the second layer on the lower side, at the same time, the cover plate 4 pushes the fixed rod 5 to move upward along the light shielding cylinder 13 until the second scale ring 502 on the upper side of the fixed rod 5 is exposed on the upper side of the light shielding cylinder 13, which indicates that the cover plate 4 is aligned with the arc-shaped clamping plate 24 of the second layer on the lower side at this time, and the stacking work of the two panel bodies 7 has been completed, then the subsequent stacking work is continued in this way, the number of the scale rings 502 exposed on the upper side of the light shielding cylinder 13 by the fixed rod 5 indicates the number of the panel bodies 7 that have been successfully stacked at present, so that the operator can intuitively observe the stacking work of the panel bodies 7 in the light shielding cylinder 13.

[0026] In the embodiment 3, on the basis of the above-mentioned embodiment 1, Figures 1-5As shown, the bottom of the light shielding cylinder 13 is fixedly connected with a frame-shaped baffle 6; the surface of the frame-shaped baffle 6 is provided with a plurality of flow guide groove structures 601 for guiding airflow downward to the center; in this embodiment, after the hot airflow is sprayed from the air jet hole structure 301 of the airflow heater 3 to the bottom of the light shielding cylinder 13, most of the hot airflow will be intercepted by the frame-shaped baffle 6, prolonging the residence time of the hot airflow in the light shielding cylinder 13, improving the heat preservation effect of the hot airflow on the arc-shaped clamping plate 24 and the panel body 7 located inside the light shielding cylinder 13, and the hot airflow remaining in the light shielding cylinder 13 will flow downward to the center of the frame-shaped baffle 6 along the flow guide groove structure 601 and into the panel body 7 waiting to be stacked below, not only can the hot airflow be used to quickly extrude the air in the panel body 7 outward in time, but also can be used to preheat the panel body 7.

[0027] Although the present disclosure has been described with reference to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present application. Therefore, the scope of the present application should be limited only by the appended claims.
