[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] Please also read Figures 1 to 6 The foam board material separation device provided by the present application is now described. The foam board material separation device comprises a base 1, a lifting mechanism 2 and a separation mechanism 3.

[0050] The base 1 is provided with a limit frame 11, which is used to place multiple foam boards 6 stacked up and down; the base 1 can be installed on the ground or on a workbench; the size of the limit frame 11 can be adjusted according to the outer dimensions of the foam boards 6 to be loaded; the limit frame 11 has limit grooves connected to the four outer corners of the foam boards 6. When multiple foam boards 6 are placed in the limit frame 11, the limit grooves can prevent each foam board 6 from detaching from the limit frame 11 in the horizontal direction.

[0051] By adopting the above technical solution, the separation device of the present application can stably fill multiple foam boards 6 at one time, reducing the work intensity of filling the foam boards 6 and saving time and effort.

[0052] The lifting mechanism 2 is arranged on the base 1 and is located below the multiple foam boards 6, and is used to drive the multiple foam boards 6 to move upward a preset distance; the preset distance is the thickness of a foam board 6. Whenever the top foam board 6 is separated from the remaining foam boards 6, the lifting mechanism 2 drives the multiple foam boards 6 to move upward a preset distance.

[0053] The separation mechanism 3 is arranged on the base 1 and is located on one side of the multiple foam boards 6; the separation mechanism 3 includes an insert plate 31 and a first cylinder 32 connected to the insert plate 31, and the first cylinder 32 is connected to the air pump 7 through a first pipe 33; the insert plate 31 is extended in the horizontal direction, and one side of the insert plate 31 faces the bottom surface of the foam board 6 of the top first layer; the first cylinder 32 is used to drive the insert plate 31 to be inserted between the foam board 6 of the top first layer and the foam board 6 of the top second layer to separate the top foam board 6 from the remaining foam boards 6.

[0054] In the embodiment of the present application, by placing multiple foam boards 6 in a limiting frame 11, the multiple foam boards 6 can be moved upward under the drive of the jacking mechanism 2, and then the foam board 6 on the top layer is separated from the remaining foam boards 6 by the separation mechanism 3.

[0055] Compared with the prior art, the foam board feeding and separation device provided in the embodiment of the present application can limit and fix the positions of multiple foam boards 6 in the limit frame 11, so that displacement will not occur. At the same time, the separation mechanism 3 can avoid the formation of negative pressure adsorption between the two foam boards 6, thereby realizing the separation of the two foam boards 6. When the suction cup is grasping, there is no longer a phenomenon of grasping two or more foam boards 6 at one time, and the operator no longer needs manual intervention, thereby improving the feeding automation effect.

[0056] In some embodiments, please refer to Figure 1 and Figure 2 As a specific implementation of the foam board material separation device provided in the present application, the separation mechanism 3 also includes a bracket 35.

[0057] The bracket 35 is arranged on the upper side of the base 1 , and has a track 34 extending toward the foam board 6 ; the inserting plate 31 is located above the bracket 35 , and the inserting plate 31 is slidably connected to the track 34 .

[0058] By adopting the above technical solution, the bracket 35 can raise the separation mechanism 3 so that the bottom surface of the plug board 31 can overlap with the fitting surface of the first layer of foam board 6 and the second layer of foam board 6 on the top layer, which provides convenience for the subsequent separation process.

[0059] In some embodiments, please refer to Figures 1 to 3 As a specific implementation of the foam board material separation device provided in the present application, the inserting plate 31 includes a main body 311, a plurality of inserting teeth 312 and a baffle 313.

[0060] The main body 311 is slidably connected to the track 34 , and the main body 311 is fixedly connected to the telescopic end of the first cylinder 32 .

[0061] The plurality of inserting teeth 312 are all connected to the side of the main body 311 facing the foam board 6 , and the plurality of inserting teeth 312 are all horizontally extended toward the foam board 6 for being inserted between two adjacent foam boards 6 .

[0062] By adopting the above technical solution, compared with the plug plate 31, the multiple insert teeth 312 can increase the separation effect while saving materials; at the same time, it also reduces the contact area between the plug plate 31 and the foam plate 6, reducing the occurrence of scratches on the foam plate 6.

[0063] The baffle 313 is disposed on the main body 311 , and an extending direction of the baffle 313 is perpendicular to an extending direction of the inserting teeth 312 .

[0064] When the first cylinder 32 drives the main body 311 to move toward the foam board 6 until the plurality of inserting teeth 312 are inserted between two adjacent foam boards 6 , the baffle 313 is suitable for abutting against the foam board 6 .

[0065] By adopting the above technical solution, the baffle 313 can play a limiting role, so that the top foam board 6 can be positioned in the front, back, left and right directions to avoid misalignment of the foam board 6 to be adsorbed.

[0066] In some embodiments, please refer to Figure 1 and Figure 3 As a specific embodiment of the foam board material separation device provided in the present application, the insertion end of each inserting tooth 312 has a first inclined platform 314 extending downwardly in an inclined direction toward the foam board 6.

[0067] In the process of inserting the inserting teeth 312 into two adjacent foam boards 6 , the ramp is suitable for being inserted between the two adjacent foam boards 6 first.

[0068] By adopting the above technical solution, since the gap between the two foam boards 6 that are fitted together up and down is very small, a first inclined platform 314 is set at the front end of the insert tooth 312. When the insert tooth 312 moves toward the foam board 6, the first inclined platform 314 can be gradually inserted between the two foam boards 6 from the small diameter end, thereby avoiding the occurrence of collision between the front end of the insert tooth 312 and the foam board 6, and improving the factory quality of the foam board 6.

[0069] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 As a specific embodiment of the foam board material separation device provided in the present application, the lifting mechanism 2 includes a bottom plate 21, a supporting plate 22 and two sets of connecting plate components.

[0070] The bottom plate 21 is fixedly disposed on the upper side of the base 1 , and the bottom plate 21 is located in the limiting frame 11 and below the plurality of foam plates 6 .

[0071] The support plate 22 is arranged above the base plate 21, and the support plate 22 and the base plate 21 are parallel to each other. The upper side of the support plate 22 is used to support the foam board 6; the upper side of the support plate 22 has an anti-slip coating, which can increase the friction between the support plate 22 and the foam board 6, so that relative displacement is not easy to occur when the support plate 22 supports the foam board 6.

[0072] Each group of connecting plate assemblies includes two connecting plates 23 hinged to each other at the center, and each connecting plate 23 is arranged between the base plate 21 and the support plate 22; wherein, the ends of the two connecting plates 23 located on the same side of the hinge center of the two connecting plates 23 in the horizontal direction are hinged to the base plate 21 and the support plate 22 respectively, and the ends of the two connecting plates 23 on the other side are slidably connected to the base plate 21 and the support plate 22 in the horizontal direction respectively.

[0073] Among them, a second cylinder 25 is also provided between the two groups of connecting plate assemblies and the bottom plate 21, and the second cylinder 25 is connected to the air pump 7 through a second pipe 26; the second cylinder 25 is used to drive the two connecting plate assemblies to swing around the hinge center to increase or decrease the distance between the support plate 22 and the bottom plate 21.

[0074] By adopting the above technical solution, the two connecting plate assemblies form a scissors hinge structure. When the distance between the connecting plate assemblies in the left and right directions increases or decreases, the distance between the connecting plate assemblies in the up and down directions also decreases or increases synchronously; therefore, when the second cylinder 25 drives the two connecting plate assemblies to swing around the hinge center, the distance between the support plate 22 and the base plate 21 can be increased or decreased.

[0075] In some embodiments, see Figure 4 As a specific embodiment of the foam board material separation device provided in the present application, both the bottom plate 21 and the support plate 22 have guide grooves 24 that penetrate perpendicularly to the swinging direction of the connecting plate 23, and the sliding end of each connecting plate 23 is slidably connected to the corresponding guide groove 24.

[0076] By adopting the above technical solution, the guide groove 24 limits the sliding direction and range of the connecting plate 23 , and the staff can adjust the sliding range of the connecting plate 23 by adjusting the length of the guide groove 24 .

[0077] In some embodiments, see Figure 1 , Figure 2 , Figure 5 and Figure 6 As a specific implementation of the foam board feed separation device provided in the present application, the foam board feed separation device also includes a blowing mechanism 4.

[0078] The purge mechanism 4 is disposed on the limiting frame 11 , and the purge mechanism 4 and the separation mechanism 3 are respectively located on two opposite sides of the plurality of foam plates 6 .

[0079] By adopting the above technical solution, when the separation mechanism 3 separates the top layer of foam board 6 from the remaining foam boards 6 , the blowing mechanism 4 can blow gas toward the upper and lower sides of the foam board 6 , in order to remove dust adsorbed on the foam board 6 .

[0080] In some embodiments, please refer to Figure 5 and Figure 6 As a specific implementation of the foam board material separation device provided in the present application, the blowing mechanism 4 includes a blower box 41 and two nozzles 42.

[0081] The bellows box 41 has a hollow structure and is disposed on the limiting frame 11 . The bellows box 41 is connected to the air pump 7 via a third pipe 43 . The air pump 7 is used to introduce gas into the bellows box 41 .

[0082] Both nozzles 42 have a long strip structure, and the length of each nozzle 42 is the same as or slightly smaller than the length of the foam board 6; the two nozzles 42 are arranged on the side of the blow box 41 facing the foam board 6, and each nozzle 42 is connected to the inside of the blow box 41.

[0083] By adopting the above technical solution, the two nozzles 42 blow the gas to the upper side and the lower side of the top foam board 6 respectively.

[0084] In some embodiments, please refer to Figure 5 and Figure 6 As a specific embodiment of the foam board material separation device provided in the present application, each nozzle 42 has a second inclined platform 421 inclined toward the foam board 6, and the second inclined platform 421 has an outlet hole for exhausting gas.

[0085] By adopting the above technical solution, the second inclined platform 421 can change the gas outlet direction of the nozzle 42, ensuring that the gas outlet directions of the two nozzles 42 are inclined toward the foam plate 6, reducing gas diffusion and improving the purging effect.

[0086] In some embodiments, see Figure 1 As a specific implementation of the foam board loading separation device provided in the present application, the loading separation device also includes a controller 5.

[0087] The controller 5 is arranged on the base 1 and is electrically connected to the lifting mechanism 2 and the separation mechanism 3 respectively; the controller 5 can be an industrial computer or a single chip microcomputer.

[0088] Among them, after the topmost foam board 6 is separated from the remaining foam boards 6, the controller 5 controls the lifting mechanism 2 to drive the remaining foam boards 6 to move upward a first preset distance; at the same time, the controller 5 controls the separation mechanism 3 to move toward the foam board 6 a second preset distance. After the top layer of foam boards 6 is loaded, the controller 5 controls the separation mechanism to move back in the opposite direction.

[0089] It should be supplemented that the first preset distance is the thickness of a single foam board 6 , and the second preset distance is the maximum distance that the baffle 313 can move toward the foam board 6 .

[0090] By adopting the above technical solution, the controller can realize the automatic operation of the foam board feeding and separation device, reduce the labor cost, and improve the feeding efficiency of the foam board 6.

[0091] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
