Description

Technical Field

[0001] The utility model relates to the technical field of processing machinery, in particular to an intelligent vacuum platform and a plate cutting device. Background Art

[0002] In order to produce and process aluminum substrates, companies need to cut the aluminum substrates into long strips of light and embed light beads on the long strips of light.

[0003] A Chinese patent with publication number CN116423221A discloses a plate cutting machine, which is provided with a sliding platform for transporting plates to be cut. A plurality of vacuum holes are evenly arranged on the sliding platform, and the plurality of vacuum holes are connected to the air inlet end of a vacuum pump through an air pipe. The plurality of vacuum holes can generate a negative pressure adsorption force under the action of the vacuum pump, thereby adsorbing the plates to be cut onto the sliding platform through the adsorption effect of the vacuum holes.

[0004] In the actual processing process, in order to adsorb aluminum-based plates of different sizes, the vacuum holes need to be spread across the entire plane of the sliding platform as much as possible. However, the plane size of the aluminum-based plate to be cut is usually smaller than the plane size of the sliding platform. This results in that after the aluminum substrate is in place, a part of the vacuum holes on the sliding platform are not covered by the aluminum substrate, and these uncovered vacuum holes are still connected to the vacuum pump, and there is still vacuum airflow inside them. These vacuum airflows will affect the vacuum degree of the adjacent vacuum holes covered by the aluminum substrate, thereby affecting the adsorption strength of the sliding platform on the plate. In severe cases, it will cause the plate to move during the transmission process, thereby affecting the accuracy of plate cutting. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0029] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0030] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] In this example, see Figure 1 to Figure 2The embodiment of the utility model provides an intelligent vacuum platform 1, which is used in a plate cutting machine in conjunction with a negative pressure device for adsorbing and conveying the plate to be cut. The negative pressure device may include a vacuum pump and a vacuum tube. The plate to be cut may be an aluminum substrate. The intelligent vacuum platform 1 may include a platform body 11, a plurality of air holes 12, an intelligent valve core 13, and an air cavity. The number of platform bodies 11 may be set to two, and the two platform bodies 11 may be arranged in parallel. A plurality of air holes 12 are evenly or unevenly arranged on the platform body 11, and there is a vacuum airflow inside the platform body 11 to form a negative pressure to adsorb the plate; the air inlet of the air hole 12 is arranged on the surface of the platform body 11, and is spread over the surface of the platform body 11 as much as possible, and the surface is used to place the end face of the plate to be cut, so that the platform body 11 can adsorb plates of various sizes. The intelligent valve core 13 is arranged inside the platform body 11, one end of which is connected to the air hole 12 on the platform body 11, and the other end is connected to the negative pressure device; the intelligent valve core 13 can automatically control the connection and disconnection between the negative pressure device and the outside of the platform body 11 according to whether the air hole 12 is blocked, thereby ensuring the vacuum degree in the air hole 12 blocked by the plate and the adsorption strength of the plate by the intelligent vacuum platform 1. The air cavity is arranged inside the platform body 11, which is used to connect the intelligent valve core 13 and the negative pressure device, that is, when the negative pressure device is turned on, the order of air flow entering the vacuum pump from the outside of the intelligent vacuum platform 1 is air hole 12→intelligent valve core 13→air cavity→vacuum tube→vacuum pump.

[0032] In some embodiments, the smart valve core 13 is tightly arranged on the outside of the air outlet of the air hole 12, that is, the air hole 12 is arranged above the smart valve core 13; the number of smart valve cores 13 is less than or equal to the number of air holes 12. When the number of smart valve cores 13 is equal to the number of air holes 12, one smart valve core 13 corresponds to one air hole 12 above; when the number of smart valve cores 13 is less than the number of air holes 12, one smart valve core 13 corresponds to at least two air holes 12 above.

[0033] It is understandable that the smart valve core 13 may also be disposed in the air hole 12 , and the smart valve core 13 is closely attached to the side wall of the air hole 12 . In this case, the number of the smart valve cores 13 corresponds to the number of the air holes 12 .

[0034] The number of air cavities is set to be more than two, each of which is connected to a certain number of intelligent valve cores 13, and a valve is provided between the negative pressure device and each of the air cavities to control the communication between the air cavity and the negative pressure device. When the valve between the air cavity and the negative pressure device is opened to form a vacuum inside the air cavity, the valve of each air cavity is opened at intervals. That is, when the valve between the first air cavity and the negative pressure device is opened, the first air cavity and the interiors of each intelligent valve core 13 connected thereto are vacuumed, and then the valve between the second air cavity and the negative pressure device is opened, and so on, until all valves are opened, and the intelligent vacuum platform 1 reaches a working state capable of adsorbing plates. Compared with opening all valves at once to form a vacuum state in all air cavities at the same time, the method of opening at intervals can effectively reduce the load pressure of the negative pressure device, and the total time consumption is less than the method of opening at once, which ensures the working reliability of the negative pressure device while saving working time.

[0035] Read also Figure 3 In some embodiments, the smart valve core 13 may include a valve body assembly 131, a spring 132, an opening and closing member 133, a first sealing ring 134, a second sealing ring 135 and a filter 136. An air flow channel is formed inside the valve body assembly 131. The spring 132 and the opening and closing member 133 are both arranged in the valve body assembly 131. The opening and closing member 133 is connected to the spring 132. The spring 132 is a compression spring 132. The opening and closing member 133 may be a valve ball or a valve plate. The spring 132 and the opening and closing member 133 cooperate with each other to realize the automatic opening and closing of the smart valve core 13. The first sealing ring 134 is arranged on the outer peripheral side of the valve body assembly 131, which is used to block the gap between the valve body assembly 131 and the platform body 11 to prevent the vacuum airflow formed by the negative pressure from entering the gap between the valve body assembly 131 and the platform body 11. The second sealing ring 135 is arranged inside the valve body assembly 131 to block the gaps between the internal components of the valve body assembly 131 to prevent the vacuum airflow formed by the negative pressure from leaking out and affecting the vacuum degree. The filter 136 is arranged on the path of the airflow channel inside the valve body assembly 131 to filter the sundries or debris outside the platform body 11 to prevent them from entering the inside of the valve body assembly 131 and affecting the performance of the smart valve core 13.

[0036] In some embodiments, the valve body assembly 131 may include a first valve body 1311, a second valve body 1312, a first inner cavity 1313, a second inner cavity 1314, a first through hole 1315, and a second through hole 1316. The first valve body 1311 and the second valve body 1312 are tightly connected to form a housing of the valve body assembly 131. The first valve body 1311 and the second valve body 1312 may be interference fit or threaded. The first inner cavity 1313 and the second inner cavity 1314 are both formed inside the second valve body 1312. The first inner cavity 1313 is connected to the air hole 12 on the platform body 11, and the second inner cavity 1314 is connected to the negative pressure device. The first inner cavity 1313 and the second inner cavity 1314 are connected to each other inside the valve body assembly 131. After the vacuum airflow formed by the negative pressure enters the valve body assembly 131 from the outside of the valve body assembly 131, it first passes through the first inner cavity 1313 and then passes through the second inner cavity 1314. The second inner cavity 1314 can be specifically connected to the negative pressure device through the air cavity.

[0037] Among them, the diameter of the second inner cavity 1314 is smaller than the diameter of the first inner cavity 1313, one end of the spring 132 is arranged in the first inner cavity 1313, the other end of the spring 132 is connected to the second inner cavity 1314, the opening and closing member 133 is arranged in the first inner cavity 1313, and the filter 136 is arranged on the side of the opening and closing member 133 away from the second inner cavity 1314; and the opening and closing member 133 is connected to one end of the spring 132 arranged in the first inner cavity 1313, the diameter of the opening and closing member 133 is larger than the diameter of the second inner cavity 1314, and the diameter of the opening and closing member 133 is smaller than the diameter of the first inner cavity 1313 so that it can block the connection between the second inner cavity 1314 and the first inner cavity 1313 under corresponding conditions.

[0038] Specifically, when the air hole 12 connected to the smart valve core 13 is not covered by an obstruction, the vacuum gas flow passing through the inside of the smart valve core 13 is large, and the vacuum suction force is greater than the supporting force generated by the deformation of the spring 132. The opening and closing member 133 compresses the spring 132 and moves toward the second inner cavity 1314 to block the connection between the second inner cavity 1314 and the first inner cavity 1313, close the smart valve core 13, and thus block the vacuum channel between the negative pressure device and the outside of the smart vacuum platform 1; when the air hole 12 connected to the smart valve core 13 is covered by an obstruction, the vacuum flow passing through the inside of the smart valve core 13 is small, and the suction force generated by the vacuum flow is insufficient to overcome the elastic force of the spring 132, and thus is insufficient to attract the opening and closing member 133 and the second inner cavity 1314, so that the smart valve core 13 is always kept in an open state.

[0039] In some embodiments, the first through hole 1315 is disposed on the first valve body 1311, the first through hole 1315 and the first inner cavity 1313 are disposed on the same axis, and the first through hole 1315 connects the first inner cavity 1313 with the air hole 12. The second through hole 1316 is disposed on the second valve body 1312, the second through hole 1316 and the second inner cavity 1314 are disposed on the same axis, and the second through hole 1316 connects the second inner cavity 1314 with the external environment of the second valve body 1312, that is, the second through hole 1316 connects the second valve body 1312 with the air cavity. Preferably, the first through hole 1315, the first inner cavity 1313, the opening and closing member 133, the spring 132, the second inner cavity 1314 and the second through hole 1316 are all disposed on the same axis.

[0040] Read also Figure 4 and Figure 5 In some embodiments, the inner wall of the first valve body 1311 defines the first through hole 1315, and at one end of the first through hole 1315 close to the second valve body 1312, the inner wall of the first valve body 1311 expands outward to form a first step portion 1311a. The first step portion 1311a includes a horizontal surface and a vertical surface connected to each other, and the filter screen 136 is disposed between the horizontal surface and the second valve body 1312; the vertical surface is tightly connected to the outer wall of the second valve body 1312.

[0041] The inner wall of the second valve body 1312 includes an expanded first section 1312a and a contracted second section 1312b, wherein the first section 1312a defines a first inner cavity 1313, and the second section 1312b defines a second inner cavity 1314. The inner wall of the second valve body 1312 at one end close to the second inner cavity 1314 defines the second through hole 1316, and the diameter of the second through hole 1316 is smaller than the diameter of the second inner cavity 1314, so that a second step portion 1312c is formed between the inner wall of the second valve body 1312 at one end close to the second inner cavity 1314 and the inner wall of the second section 1312b, and the end of the spring 132 connected to the second inner cavity 1314 is arranged on the second step portion 1312c.

[0042] The second valve body 1312 also includes a first annular groove 1312d and a second annular groove 1312e. The first annular groove 1312d is arranged on the outer side of one end of the second valve body 1312 close to the first valve body 1311, and the above-mentioned first sealing ring 134 is arranged on the first annular groove 1312d; the second annular groove 1312e is arranged on the outer side of one end of the second valve body 1312 close to the air cavity, and the above-mentioned second sealing ring 135 is arranged on the second annular groove 1312e.
