Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and in particular to a fragment suction cup. Background Technology

[0002] Some fragile, sheet-like products inevitably break during production, transportation, and use due to improper handling. Currently, there are no good methods for handling the fragments, and most of them are cleaned manually. For products with sharp edges after breakage, such as glass, extra care must be taken during the cleaning process to avoid being cut by the fragments. Traditional fragment suction cups can be used to pick up broken sheet-like products, making it easy to transfer and clean them. However, when cleaning products that are not easy to pick up, it is necessary to improve the adsorption strength of traditional fragment suction cups. Especially when picking up some disc-shaped fragments, the difficulty of cleaning is often increased because the fragments are upside down. Therefore, a fragment suction cup is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a debris suction cup to solve the problem of using a suction cup to pick up debris in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A debris suction cup, comprising:

[0006] A negative pressure chamber is provided with a vacuum tube inside the negative pressure chamber. An air suction hole is opened on the side wall of the vacuum tube, and the air suction hole connects the negative pressure chamber and the vacuum tube.

[0007] A suction cup is provided on the lower side of the negative pressure chamber. A suction nozzle is provided on the lower side of the suction cup. A steel ball mounting plate is provided between the suction cup and the negative pressure chamber. A steel ball cavity is provided in the steel ball mounting plate. The steel ball cavity connects the suction nozzle and the negative pressure chamber. A steel ball is disposed in the steel ball cavity. The radial dimension of the steel ball is set smaller than the radial dimension of the steel ball cavity.

[0008] To achieve the above technical solution, a vacuum tube is installed inside the negative pressure chamber, and an air compressor is connected to the vacuum tube. Compressed air is injected outwards at a height through the vacuum tube, forming a jet inside the nozzle and generating a suction flow. Under the suction effect, the air in the compressed air chamber is continuously drawn away by the nozzle of the vacuum tube through the air intake hole and sprayed to the outside, thereby reducing the pressure inside the compressed air chamber to below atmospheric pressure, forming a certain degree of vacuum to complete the suction action of the suction nozzle at the bottom of the suction cup.

[0009] By setting a steel ball cavity inside the steel ball mounting plate, the suction nozzle can generate suction force under the action of entrapment, thereby adsorbing debris onto the suction nozzle. For suction nozzles without adsorbed material, in order to avoid the loss of negative pressure energy, the steel balls arranged in the steel ball cavity will move upward under the action of negative pressure to reduce the loss of negative pressure energy.

[0010] In one embodiment of this utility model, a sealing gasket is provided between the steel ball mounting plate and the negative pressure chamber, and an air cavity is provided inside the sealing gasket, the air cavity connecting the steel ball cavity and the negative pressure chamber.

[0011] To achieve the above technical solution, the sealing reliability between the steel ball mounting plate and the negative pressure chamber can be improved by setting a sealing gasket, and the air cavity can guide the airflow out of the steel ball cavity, thereby improving the airflow stability in the negative pressure chamber.

[0012] In one embodiment of the present invention, the air cavity is a conical air cavity with the long side end of the conical air cavity located near the steel ball cavity, and the radial dimension of the short side end of the air cavity is set to be smaller than the radial dimension of the steel ball.

[0013] To achieve the above technical solution, the air chamber is set as a conical cross-section air chamber, and the radial dimension of the short side end of the air chamber is set to be smaller than the radial dimension of the steel ball. After the steel ball is sucked up under negative pressure, the steel ball can block the channel of the air chamber connected to the nozzle where there is no adsorbed material, thereby avoiding the loss of negative pressure energy. In addition, it can increase the suction force generated at other normally operating nozzles.

[0014] In one embodiment of the present invention, an air inlet is provided at one end of the vacuum tube, and an exhaust outlet is provided at the other end of the vacuum tube.

[0015] To achieve the above technical solution, by setting an external compressed air source through the air inlet and cooperating with the exhaust port, the flow stability of compressed air in the vacuum tube can be guaranteed.

[0016] In one embodiment of this utility model, a sound-absorbing cover is provided between the vacuum tube output end and the exhaust port.

[0017] To achieve the above technical solution, the soundproof cover can reduce the noise at the output end of the vacuum tube.

[0018] In one embodiment of the present invention, a steel ball seat is provided at the bottom of the steel ball cavity, and a steel ball hole is provided on the steel ball seat to hold the steel ball. The steel ball hole is provided with a flow channel evenly distributed around its circumference.

[0019] To achieve the above technical solution, a steel ball hole is provided on the steel ball holder to support the steel ball. The flow distribution groove can evenly distribute the airflow through the steel ball cavity and generate a small adsorption force in the initial stage of adsorbing debris, thereby improving the adsorption stability of debris.

[0020] In one embodiment of this utility model, a buffer pad is provided on the lower side of the suction nozzle.

[0021] The above technical solution improves the adsorption stability of the nozzle and reduces the damage to the nozzle caused by the adsorbent.

[0022] As described above, the debris suction cup of this utility model has the following beneficial effects: by setting a vacuum tube in the negative pressure chamber and connecting the vacuum tube to an air compressor, the vacuum tube sprays compressed air outward at a high height, forming a jet at the nozzle inside the vacuum tube, generating a suction flow. Under the suction effect, the air in the air pressure chamber is continuously drawn away by the nozzle of the vacuum tube through the air intake hole and sprayed to the outside, thereby reducing the pressure in the air pressure chamber to below atmospheric pressure, forming a certain vacuum degree to complete the suction action of the suction nozzle at the bottom of the suction cup.

[0023] By setting a steel ball cavity inside the steel ball mounting plate, the suction nozzle can generate suction force under the action of entrapment, thereby adsorbing debris onto the suction nozzle. For suction nozzles without adsorbed material, in order to avoid the loss of negative pressure energy, the steel balls arranged in the steel ball cavity will move upward under the action of negative pressure to reduce the loss of negative pressure energy.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please see Figures 1 to 5 This utility model provides a debris suction cup, including a vacuum tube 2 disposed in a negative pressure chamber 1, a suction hole 3 opened on the side wall of the vacuum tube 2, the suction hole 3 connecting the negative pressure chamber 1 and the vacuum tube 2, a suction cup 4 disposed on the lower side of the negative pressure chamber 1, a suction nozzle 5 disposed on the lower side of the suction cup 4, a steel ball mounting plate 6 disposed between the suction cup 4 and the negative pressure chamber 1, a steel ball cavity 7 disposed in the steel ball mounting plate 6, the steel ball cavity 7 connecting the suction nozzle 5 and the negative pressure chamber 1, a steel ball 8 disposed in the steel ball cavity 7, the radial dimension of the steel ball 8 being smaller than the radial dimension of the steel ball cavity 7.

[0033] By installing a vacuum tube 2 inside the negative pressure chamber 1, and connecting the vacuum tube 2 to an air compressor, compressed air is injected outwards at a height through the vacuum tube 2. A jet is formed at the nozzle inside the vacuum tube 2, generating a suction flow. Under the suction effect, the air in the compressed air chamber is continuously drawn away by the nozzle of the vacuum tube 2 through the air intake hole 3 and sprayed to the outside, thereby reducing the pressure inside the compressed air chamber to below atmospheric pressure, forming a certain degree of vacuum to complete the suction action of the suction nozzle 5 at the bottom of the suction cup 4.

[0034] By providing a steel ball cavity 7 inside the steel ball mounting plate 6, the suction nozzle 5 can generate suction force under the action of suction, thereby adsorbing the debris onto the suction nozzle 5. For the suction nozzle 5 where there is no adsorbed material, in order to avoid the loss of negative pressure energy, the steel ball 8 arranged in the steel ball cavity 7 will move upward under the action of negative pressure to reduce the loss of negative pressure energy.

[0035] A sealing gasket 9 is provided between the steel ball mounting plate 6 and the negative pressure chamber 1. An air cavity 10 is provided inside the sealing gasket 9. The air cavity 10 connects the steel ball cavity 7 and the negative pressure chamber 1. By providing the sealing gasket 9, the sealing reliability between the steel ball mounting plate 6 and the negative pressure chamber 1 can be improved. In addition, the air cavity 10 can guide the airflow out of the steel ball cavity 7 and improve the airflow stability in the negative pressure chamber 1.

[0036] The air chamber 10 is a conical air chamber 10 with its long side end located near the steel ball chamber 7. The radial dimension of the short side end of the air chamber 10 is smaller than the radial dimension of the steel ball 8. By setting the air chamber 10 to have a conical cross-section and setting the radial dimension of the short side end of the air chamber 10 to be smaller than the radial dimension of the steel ball 8, after the steel ball 8 is sucked up under negative pressure, the steel ball 8 can block the channel of the air chamber 10 connected to the nozzle 5 where there is no adsorbed material, thereby avoiding the loss of negative pressure energy. In addition, it can increase the suction force generated at other normally operating nozzles 5.

[0037] One end of the vacuum tube 2 is provided with an air inlet 11, and the other end of the vacuum tube 2 is provided with an exhaust port 12. By providing an external compressed air source through the air inlet 11, and in conjunction with the exhaust port 12, the flow stability of compressed air in the vacuum tube 2 can be ensured.

[0038] A soundproof cover 13 is provided between the output end of the vacuum tube 2 and the exhaust port 12. The soundproof cover 13 can reduce the noise at the output end of the vacuum tube 2.

[0039] A steel ball seat 14 is provided at the bottom of the steel ball cavity 7. The steel ball seat 14 is provided with steel ball holes 15 to hold steel balls 8. The steel ball holes 15 are evenly distributed with flow channels 16 in the circumference. By providing steel ball holes 15 on the steel ball seat 14 to hold steel balls 8, the flow channels 16 can evenly distribute the airflow in the steel ball cavity 7, and can also generate a small adsorption force in the initial stage of adsorbing debris, thereby improving the adsorption stability of debris.

[0040] A buffer pad 17 is provided on the lower side of the suction nozzle 5 to improve the adsorption stability of the suction nozzle 5 and reduce the damage to the suction nozzle 5 caused by the adsorbent.

[0041] This invention features a vacuum tube installed inside a negative pressure chamber, connected to an air compressor. The vacuum tube ejects compressed air outwards at a high height, creating a jet stream at the nozzle inside the vacuum tube. This jet stream generates entrainment flow, and under the entrainment effect, the air in the compressed air chamber is continuously drawn away through the suction hole and ejected to the outside. This reduces the pressure inside the compressed air chamber to below atmospheric pressure, creating a certain degree of vacuum to complete the suction action of the suction nozzle at the bottom of the suction cup.

[0042] By setting a steel ball cavity inside the steel ball mounting plate, the suction nozzle can generate suction force under the action of entrapment, thereby adsorbing debris onto the suction nozzle. For suction nozzles without adsorbed material, in order to avoid the loss of negative pressure energy, the steel balls arranged in the steel ball cavity will move upward under the action of negative pressure to reduce the loss of negative pressure energy.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
