Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology, and relates to a quick connector used for an automated line vacuum carrier, in particular to a self-sealing vacuum suction quick connection device and an automated line vacuum carrier. Background Art

[0002] With the advancement of product technology, conventional purely mechanical clamping carriers are no longer able to meet process requirements. The industry urgently needs vacuum adsorption carriers to replace traditional clamping carriers. Furthermore, with the increasing prevalence of automated production lines, traditional vacuum pipe joints are unable to achieve the rapid vacuum release function. Furthermore, the current industry has too few and too high-priced connectors that can achieve this, failing to meet the demands of 3C automated production lines.

[0003] For example, Chinese patent literature has disclosed an automatic lifting door bottom sealing strip [Chinese Patent No.: 201920494175.0], a plunger-type quick connector, including a male connector body and a female connector body. The utility model designs the male and female parts of the quick connector into plunger-type one-way valves respectively. When the connectors are separated, the connector uses spring elastic force to press the valve core back to the sealing position to achieve sealing performance. When the connectors are combined, the interaction between the male and female connectors is used to push each other apart, opening the male and female parts of the quick connector to achieve the purpose of connection; and the utility model can eliminate the dependence of the key sealing performance on the spring elastic force, and a smaller spring can be used to save costs. It also uses common O-rings on the market, eliminating the need for special procurement, simplifying the processing technology and procurement; and the male connector spring of the male connector of the utility model is connected to the valve body and the valve core at both ends respectively. In the open state, the valve core is in a semi-suspended state. During the opening and closing process, the valve core will not directly contact the inner wall of the valve body, avoiding noise and wear.

[0004] The above-mentioned technical solution uses elastic pressure to open the valve hole, which requires precise control of the elastic coefficients of the two sets of springs. Otherwise, it is difficult to control the degree of valve opening. In addition, after long-term opening and closing, the sealing performance of the male and female connectors will deteriorate, affecting the sealing effect of the joint. Utility Model Content

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] Example 1

[0029] like Figures 1 to 3 As shown, this self-sealing vacuum quick-connect device includes a matching vacuum male connector 1 and female connector. The female connector is 21mm long, which is smaller than the common vacuum female connector (>30mm), thereby simplifying the female connector structure, reducing processing difficulty, and reducing carrier costs. The bottom of the barrel cavity of the vacuum male connector 1 is connected to the trachea connector 2. The barrel cavity of the vacuum male connector 1 elastically presses against the sealing top member A5, and the sealing top member A5 has a through hole connecting to the barrel cavity. The female connector includes a cap 8 with a vent cavity, and the vent cavity elastically presses against the sealing top member B11. The sealing top member B11 elastically blocks the top of the vent cavity. The top of the barrel cavity of the vacuum male connector 1 is pressed against the bottom of the vent cavity of the cap 8 to form a sealed connection. Negative pressure is formed in the barrel cavity of the vacuum male connector 1, driving the sealing top member B11 to open the top of the vent cavity.

[0030] A base A3 is mounted on the bottom of the barrel of the vacuum male connector 1. The center hole of the base A3 is sealed and connected to the air pipe connector 2. The base A3 and the bottom of the barrel of the vacuum male connector 1 are interference-fitted to form a sealed connection. The center hole of the base A3 reduces the connection aperture to achieve a sealed assembly with the air pipe connector 2.

[0031] like Figure 1 and Figure 3 As shown, the sealing top member A5 is a cylinder with an annular platform protruding from the outer periphery of the cylinder. A stop edge is provided at the top opening of the cylinder cavity of the vacuum suction male connector 1, and the annular platform contacts the stop edge to form a limit stop. A spring A4 is provided in the cylinder cavity of the vacuum suction male connector 1, and the bottom end of the spring A4 presses against the base A3, and the top end of the spring A4 presses against the annular platform.

[0032] Spring A4 applies elastic pressure to the top seal member A5, which is then held in place by the retaining edge. In its natural state, the cylindrical portion of top seal member A5 extends from the top opening of the vacuum connector 1. Under pressure, top seal member A5 fully retracts into the connector 1, compressing spring A4.

[0033] The top end surface of the cylindrical body is provided with an annular groove 1, within which is embedded a sealing ring 1 (6). The top end surface of the vacuum male connector 1 is provided with an annular groove 2, within which is embedded a sealing ring 2 (7). When the vacuum male connector 1 is mated with the female connector, the sealing ring 1 (6) forms a seal between the sealing top member A5 and the female connector's base B9, while the sealing ring 2 (7) forms a seal between the vacuum male connector 1 and the female connector's cap 8, ensuring a good seal after mating.

[0034] like Figure 1 As shown, a small hole is provided in the center of the top wall of cap 8, which serves as the top opening of the vent cavity. A base B9 is provided at the bottom end of cap 8, and the center hole of base B9 serves as the bottom opening of the vent cavity. Base B9 and the bottom opening of cap 8 form an interference fit to form a sealed connection. The center hole of base B9 reduces the diameter of the connection hole to achieve assembly requirements.

[0035] like Figure 4 As shown, the sealing top component B11 includes a shaft rod 11a, the top end of the shaft rod 11a is connected to the sealing head 11b through an expanding step, the bottom of the shaft rod 11a is connected to the small-diameter rod 11c through a reducing step, and the outer periphery of the shaft rod 11a is sleeved with a spring B10, the bottom end of the spring B10 presses against the base B9, and the top end of the spring B10 presses against the expanding step.

[0036] In its natural state, spring B10 exerts elastic pressure on sealing top member B11, causing sealing head 11b to block the small hole in the top wall of cap 8 under its elastic force, creating a flow-blocking state. Under negative pressure, the annular gap between small-diameter rod 11c and the through-hole of sealing top member A5 forms a negative pressure channel. Sealing top member B11 compresses spring B10, forcing sealing top member B11 away from the small hole, creating a flow gap.

[0037] The inner wall of the aperture is provided with an annular groove 3, within which is embedded a sealing ring 3 12, which surrounds the periphery of the aperture. In its natural state, spring B10 pushes sealing head 11b against sealing ring 3 12, forming a sealed connection, thereby sealing the aperture and cutting off gas flow.

[0038] The sealing head 11b can be any one of a spherical body, a conical body, a T-shaped body, and a piston body.

[0039] The arc of the spherical body faces the small hole on the top wall of the cap 8 to form a blockage. The cone of the conical body faces the small hole on the top wall of the cap 8 to form a blockage. The cylindrical part of the T-shaped body faces the small hole on the top wall of the cap 8 to form a blockage. The end of the piston body faces the small hole on the top wall of the cap 8 to form a blockage.

[0040] like Figure 1 and 2 As shown, the bottom end of the cap 8 is provided with a flange outward, and the outer periphery of the cap 8 is sleeved with a sealing gasket 13, which is overlapped on the flange. The sealing gasket 13 is installed and fixed by the flange, and the sealing gasket 13 is used to achieve the sealing of the female connector and other components.

[0041] Example 2

[0042] Based on the first embodiment, the difference of this embodiment is that:

[0043] An automated line vacuum carrier comprises the above-mentioned self-sealing vacuum quick connection device.

[0044] The quick connector in this automated line vacuum carrier works as follows:

[0045] 1. In the initial position, the spring A4 presses the sealing top piece A5, so that part of the cylindrical body of the sealing top piece A5 extends out from the top opening of the cylinder cavity of the vacuum male connector 1.

[0046] 2. When the female connector needs to be docked for vacuum suction, the vacuum suction male connector 1 is driven upward by the external structure, and the sealing top member A5 contacts the bottom end of the cap 8 to form a primary seal; the vacuum suction male connector 1 continues to move upward under the external force, and the sealing top member A5 compresses the spring A4 and retracts it completely into the cylindrical cavity of the vacuum suction male connector 1, completing the secondary sealing docking between the vacuum suction male connector 1 and the female connector.

[0047] 3. Negative pressure is introduced through the trachea connector 2 to form a negative pressure in the connecting cavity between the vacuum male connector 1 and the female connector. Under the action of negative pressure, the sealing top piece B11 moves downward, causing the sealing head 11b to open the top opening of the vent cavity, completing the vacuuming action of the vacuum cavity.

[0048] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
