In order to solve the technical problems mentioned in the background art, the utility model provides a vacuum device and a vacuum conveying device, because the adsorption surface is provided with an adsorption through hole communicated with a vacuum cavity, the end surface of one end of the vacuum cavity structure is provided with an air blowing port communicated with the vacuum cavity, and the other end surface is provided with an air suction port communicated with the vacuum cavity, the area of the cross section of the vacuum cavity near the air blowing port is smaller than that of the cross section of the vacuum cavity near the air suction port, therefore, by arranging the air blowing port, the airflow velocity of the end of the vacuum cavity near the air blowing port can be improved, the adsorption force of the adsorption through hole near the air blowing port is increased, the difference between the adsorption force of the adsorption through hole near the air blowing port and the adsorption through hole near the air suction port is reduced, the uniformity of the adsorption through hole near the vacuum device is improved, in addition, the adsorption force of the adsorption through hole near the vacuum cavity near the air suction port is smaller than that of the cross section of the vacuum cavity near the air suction port is increased, the uniformity of the adsorption force of a plurality of adsorption through holes is further avoided, and when the vacuum device is applied to the vacuum conveying device, and the adsorption efficiency of the vacuum device near the vacuum conveying device is reduced.

The application is illustrated in detail below by means of specific examples:

referring to fig. 1, 2 and 3 in combination, an embodiment of the present application provides a vacuum apparatus 100, where the vacuum apparatus 100 includes a vacuum cavity structure 110 and a blower 120, the vacuum cavity structure 110 is hollow to form a vacuum cavity 111, the vacuum cavity 111 has an adsorption surface 1111, a plurality of adsorption through holes 1112 communicating with the vacuum cavity 111 are formed on the adsorption surface 1111, the adsorption through holes 1112 are used for adsorbing a piece to be adsorbed, an air blowing port 112 communicating with the vacuum cavity 111 is formed on an end surface of one end of the vacuum cavity structure 110, an air suction port 113 communicating with the vacuum cavity 111 is formed on an end surface of the other end, an area of a cross section of the vacuum cavity 111 near the air blowing port 112 is smaller than an area of a cross section of the vacuum cavity 111 near the air suction port 113, and the adsorption surface 1111 is located between the air blowing port 112 and the air suction port 113; the blower 120 includes a suction port 121 and a first air outlet 122, which are communicated with each other, the suction port 121 is communicated with the suction port 113, and the first air outlet 122 is communicated with the air blowing port 112.

The vacuum chamber 111 has an adsorption surface 1111 thereon, and it is understood that the adsorption surface 1111 is located outside the chamber wall of the vacuum chamber 111.

In this embodiment, by providing the air blowing port 112 communicating with the vacuum chamber 111 on the end surface of one end of the vacuum chamber structure 110 and providing the air suction port 113 communicating with the vacuum chamber 111 on the end surface of the other end, the flow rate of the air flow in the vacuum chamber 111 near the air blowing port 112 can be increased, thereby increasing the adsorption force of the plurality of adsorption through holes 1112 near the air blowing port 112, further reducing the difference between the adsorption force of the plurality of adsorption through holes 1112 near the air suction port 113 and the adsorption force of the plurality of adsorption through holes 1112 near the air blowing port 112, improving the uniformity of the adsorption force of the plurality of adsorption through holes 1112 on the adsorption surface 1111, in addition, by making the area of the cross section of the vacuum chamber 111 near the air blowing port 112 smaller than the area of the cross section of the vacuum chamber 111 near the air suction port 113, and making the suction port 121 communicate with the air blowing port 113, the first air outlet 122 communicates with the air blowing port 112, on one hand, by using a fan 120, and the flow rate of the air flow entering the vacuum chamber 111 is smaller than the air flow of the air flow through the air suction port 113, thereby reducing the difference between the adsorption force of the plurality of adsorption through holes 1112 near the air blowing port 113, and the vacuum chamber 111 in a negative pressure state, thereby making the adsorption force of the vacuum chamber 111 in a plurality of adsorption pieces near the vacuum chamber 1112, and the cross section of the vacuum chamber 111 can be increased, and the suction force of the cross section of the air flow can be increased, and the cross section of the vacuum chamber 111 near the vacuum chamber 111 can be made more uniformly by adopting the adsorption force of the suction through the suction port 111, and the suction port 111. Thus, when the vacuum apparatus 100 is applied to the vacuum transfer device 200, the uniformity of the suction force of the suction ports communicating with the plurality of suction through holes 1112 can be improved, thereby reducing the failure rate of the suction-to-be-suctioned member during the transfer of the vacuum transfer device 200.

Optionally, the suction port 121 and the suction port 113 and the first air outlet 122 and the air blowing port 112 pass through a hose 130. By providing the hose 130, the installation position of the blower 120 can be flexibly set.

Since the direction of the air flow in the vacuum chamber 111 is from the air blowing port 112 to the air suction port 113, the flow rate of the air flow in the vacuum chamber 111 near the air blowing port 112 is small, the flow rate of the air flow in the vacuum chamber 111 near the air suction port 113 is large, and thus, in the direction in which the air blowing port 112 is directed to the air suction port 113 (the direction indicated by the arrow X in fig. 2), the flow rate of the air flow in the vacuum chamber 111 is gradually increased, and based on this, in order to ensure the uniformity of the adsorption force of the plurality of adsorption through holes 1112, in some possible embodiments, the plurality of adsorption through holes 1112 are uniformly provided on the adsorption surface 1111, and the area of the cross section of the vacuum chamber 111 is gradually increased in the direction in which the air blowing port 112 is directed to the air suction port 113, as seen in fig. 2 and 3.

Since the area of the cross section of the vacuum chamber 111 increases gradually along the direction in which the air blowing port 112 points to the air suction port 113, the space in which the vacuum chamber 111 increases gradually along the direction in which the air blowing port 112 points to the air suction port 113 can be used to accommodate the increasing air flow, so that the pressure in the vacuum chamber 111 is prevented from increasing near the air suction port 113, and the uniformity of the adsorption force of the plurality of adsorption through holes 1112 is ensured.

Since the flow of the air flow through the air-blow port 112 is smaller than the flow of the air flow through the air-suction port 113, in order to minimize the difference between the flow rate of the air flow through the air-blow port 112 and the flow rate of the air flow through the air-suction port 113, in some possible embodiments, see fig. 2, the diameter of the air-blow port 112 is smaller than the diameter of the air-suction port 113.

Thus, when the diameter of the air blowing port 112 is smaller than the diameter of the air suction port 113, the uniformity of the suction force of the plurality of suction through holes 1112 can be further ensured.

In some possible embodiments, the blower 120 further includes a second air outlet 123, where the second air outlet 123 is used to communicate with the external environment, so that the flow rate of the air flow entering the vacuum chamber 111 through the air blowing port 112 can be made smaller than the air flow exiting the vacuum chamber 111 through the air suction port 113, so that the plurality of adsorption through holes 1112 can adsorb the to-be-adsorbed pieces.

In some possible embodiments, referring to fig. 4 and 5, a plurality of support plates 140 are provided in the vacuum chamber 111, the plurality of support plates 140 being sequentially spaced apart in a direction perpendicular to the blowing port 112 toward the suction port 113 to divide the vacuum chamber 111 into a plurality of first vacuum chambers, and a communication hole 141 being provided in each support plate 140 to communicate each first vacuum chamber with each other.

In this embodiment, since the plurality of support plates 140 are sequentially arranged in the vacuum chamber 111 at intervals along the direction of the air blowing port 112 pointing to the air suction port 113, the vacuum chamber 111 can be supported, so that the strength of the vacuum chamber structure 110 is ensured, and the situation that the vacuum chamber structure 110 deforms under the negative pressure in the vacuum chamber 111 is avoided. In addition, since the communication holes 141 are provided on each support plate 140, the plurality of first vacuum chambers can be communicated with each other through the communication holes 141, thereby ensuring that the pressures in the plurality of first vacuum chambers tend to be equal, and further ensuring that the adsorption forces of the plurality of adsorption through holes 1112 corresponding to each first vacuum chamber tend to be equal.

In some possible embodiments, referring to fig. 5, a plurality of communication holes 141 are provided on each support plate 140, the sum of the areas of the openings of the plurality of communication holes 141 is S1, the area of one side of the support plate 140 facing the first vacuum chamber 111 is S2, and s1+ (4/5) S2.

When the sum of the areas of the openings of the plurality of communication holes 141 is smaller than 4/5 of the area of the support plate 140 facing one side surface of the first vacuum chamber 111, it is explained that the aperture or width of the communication hole 141 is small, thereby affecting the flow rate of the air flow passing through the communication hole 141, and thus making it difficult to ensure that the pressure in each first vacuum chamber is approximately equal or equal, based on which S1 is equal to or greater than (4/5) S2, so that the flow rate of the air flow passing through the communication hole 141 can be ensured, and thus ensuring that the pressure in each first vacuum chamber is approximately equal.

The specific structure of the vacuum chamber structure 110 is not limited, in some possible embodiments, referring to fig. 4, 6 and 7 in combination, the vacuum chamber structure 110 includes a bottom wall 114, a top cover 115, a first side wall 116, a second side wall 117, a first end wall 118 and a second end wall 119, the bottom wall 114 is disposed opposite to the top cover 115, the first side wall 116, the first end wall 118, the second side wall 117 and the second end wall 119 are sequentially and sealingly connected and are each sealingly disposed between the bottom wall 114 and the top cover 115 to enclose the vacuum chamber 111, and the adsorption surface 1111 is located on the bottom wall 114; the first end wall 118 includes a plurality of first end plates 1181 sequentially arranged in a direction perpendicular to the direction of the air-blowing port 112 toward the air-suction port 113 (i.e., a direction indicated by a Y arrow in fig. 4), and each first end plate 1181 is provided with the air-blowing port 112; the second end wall 119 comprises a plurality of second end plates 1191 spliced in sequence along a direction perpendicular to the direction of the air blowing port 112 pointing to the air suction port 113, the plurality of second end plates 1191 are in one-to-one correspondence with the plurality of first end plates 1181, and each second end plate 1191 is provided with the air suction port 113; the two ends of each supporting plate 140 are respectively connected to the connection portions of the two adjacent first end plates 1181 and the connection portions of the two adjacent second end plates 1191 corresponding to the two adjacent first end plates 1181.

Thus, by providing the air blowing port 112 on each first end plate 1181 and providing the air suction port 113 on each second end plate 1191, the plurality of second end plates 1191 and the plurality of first end plates 1181 are in one-to-one correspondence, and uniformity of the suction force of the plurality of suction through holes 1112 corresponding to each first vacuum chamber can be ensured.

Of course, the vacuum chamber structure 110 is not limited to the above-described structure, and for example, the vacuum chamber structure 110 is a columnar structure.

Because the air flow in the vacuum chamber 111 will move towards the air suction port 113 under the action of the blower 120, and because the air suction port 113 is located in the middle of the second end plate 1191, the air flow at the edge of the vacuum chamber 111 will converge towards the middle of the vacuum chamber 111, so, in order to ensure the constancy of the flow velocity of the air flow in the vacuum chamber 111, in some possible embodiments, referring to fig. 4 and 7 in combination, the top covers 115 include a plurality of top covers 115, which are sequentially arranged along the direction perpendicular to the direction of the air blowing port 112 pointing to the air suction port 113, the top covers 115 are in one-to-one correspondence with the first vacuum chamber, each top cover 115 covers the first vacuum chamber, one side of each support plate 140 away from the bottom wall 114 is connected to the junction between two adjacent top covers 115, each top cover 115 includes a first cover 1151 and a second cover 1152 connected to each other, the junction between the first cover 1151 and the second cover 1152 is located in the direction perpendicular to the suction plane 1111 (i.e. the direction indicated by the arrow in fig. 4) above the air suction port 113 and the support plate 115 is located directly below the junction between the two cover plates 1151.

Therefore, the connection between the first cover plate 1151 and the second cover plate 1152 is higher than the first side wall 116, the second side wall 117 and the support plate 140 in the direction perpendicular to the adsorption surface 1111, and the air suction port 113 and the air blowing port 112 are located directly below the connection between the first cover plate 1151 and the second cover plate 1152 in the direction perpendicular to the adsorption surface 1111, so that the space above the connection between the air suction port 113 and the air blowing port 112 can be increased to accommodate more converging air flows, thereby ensuring the stability of the flow velocity of the air flow in the vacuum chamber 111, and further ensuring the uniformity of the adsorption force of the plurality of adsorption through holes 1112 corresponding to each first vacuum chamber.

In some possible embodiments, referring to fig. 8, the adsorption surface 1111 is provided with a plurality of parallel and spaced ventilation slots 1113, each ventilation slot 1113 being respectively in communication with a plurality of adsorption through holes 1112, and each ventilation slot 1113 being further configured to be in communication with a plurality of adsorption ports.

Through setting up a plurality of parallel and spaced ventilation slots 1113, and every ventilation slot 1113 communicates with a plurality of absorption through-holes 1112 respectively, on the one hand, when conveyer belt 210 conveyable sets up on vacuum device 100, because ventilation slot 1113 communicates with a plurality of absorption through-holes 1112 and a plurality of absorption mouth respectively, therefore, when absorption through-hole 1112 is in negative pressure state, ventilation slot 1113 and absorption mouth all are in negative pressure state, thereby can make the absorption mouth be fixed in on the conveyer belt 210 with waiting to adsorb the piece, on the other hand, because ventilation slot 1113 has certain length, therefore, ventilation slot 1113 can adjust the adsorption force of a plurality of absorption through-holes 1112, so that the adsorption force that conveys to absorption mouth department through ventilation slot 1113 tends to be equal, further guaranteed the homogeneity of the adsorption force of a plurality of absorption mouths on the conveyer belt 210.

The width of the ventilation groove 1113 is greater than or equal to the diameters of the suction through hole 1112 and the suction port.

Since the main circulation flow in the first vacuum chamber flows from the air blowing port 112 to the air suction port 113, and the air blowing port 112 is disposed in the middle of the first end plate 1181, and the air suction port 113 is disposed in the middle of the second end plate 1191, the flow rate of the main circulation flow on the connection line between the air blowing port 112 and the air suction port 113 is fastest, in other words, the adsorption force of the plurality of adsorption through holes 1112 corresponding to the main circulation flow is greater than that of the other adsorption through holes 1112, and based on this, in order to ensure the uniformity of the adsorption force of the plurality of adsorption through holes 1112, in some possible embodiments, referring to fig. 8, the interval between every two adjacent ventilation slots 1113 is equal, and the extending direction of each ventilation slot 1113 has an included angle with the direction in which the air blowing port 112 points to the air suction port 113.

Therefore, on the one hand, compared with the direction in which the ventilation groove 1113 extends and the direction in which the air blowing port 112 points to the air suction port 113 are parallel, the ventilation groove 1113 is inclined (i.e. an included angle is formed between the extending direction of the ventilation groove 1113 and the direction in which the air blowing port 112 points to the air suction port 113), so that the negative pressures of the different adsorption through holes 1112 can be adjusted, the adsorption forces of the adsorption ports communicated with the ventilation groove 1113 tend to be equal, and the uniformity of the adsorption forces of the adsorption ports is ensured. On the other hand, the inclined ventilation grooves 1113 can generate a component force perpendicular to the conveying direction of the member to be suctioned, thereby preventing the risk of the member to be suctioned from being deviated with respect to the conveyor belt 210 during the conveying of the conveyor belt 210.

The included angle refers to an acute angle or a right angle. Preferably, the extending direction of each ventilation slot 1113 forms an angle of 45 ° with the direction in which the air-blowing port 112 is directed toward the air-suction port 113.
