[0038] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0039] After loading a tank with material, it is usually necessary to seal the tank opening to facilitate transportation and storage. Existing tanks typically use a pressurized cylinder to press the sealing cap against the tank opening. However, the stroke of the pressurized cylinder is difficult to control, and the applied pressure directly acts on the tank without a buffering process, which can easily damage the tank opening.

[0040] An embodiment of the present invention provides a press-fitting device for a sealing cover, which can solve the above-mentioned problem and will be described in detail below.

[0041] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the press-fitting device of an embodiment of the present invention when applying pressure. Figure 2This is a diagram showing the positional relationship between the press-fitting cylinder and the gasket when the press-fitting device does not grab the sealing cover.

[0042] The pressing device of the sealing cover includes a C-shaped seat 1, a servo pressure cylinder 2, a pressing cylinder 3, a pressing cylinder 3, a pressing mold 31, a gasket 4 and a cylinder 6. The pressing cylinder 3 is connected to the servo pressure cylinder 2. The pressing cylinder 3 is provided with a clamping jaw 30 which can move axially along the pressing cylinder 3. The pressing mold 31 is connected to the pressing cylinder 3. An avoidance groove 311 is provided on the pressing mold 31. The avoidance groove 311 is provided along the axial direction of the pressing mold 31. One end of the clamping jaw 30 is located in the avoidance groove 311 and can move along the avoidance groove 311. The gasket 4 is located below the pressing mold 31. The gasket 4 is used to place the charging tank, and the gasket 4 is connected to the cylinder 6, so that the charging tank on the gasket 4 is driven to rise and fall by the cylinder 6.

[0043] The C-shaped seat 1 provides an installation position for the servo cylinder 2, the pad 4 and the cylinder 6. The clamp 30 grabs the sealing cover, and the servo cylinder 2 drives the pressing cylinder 3 to move and then drives the pressing mold 31 to move, and presses the sealing cover grabbed by the clamp 30 down to the tank port of the charging tank and presses it tightly, and sets the sealing cover at the tank port. Since the charging tank is connected to the cylinder 6, the charging tank can move downward a certain distance when the servo cylinder 2 presses down the sealing cover, thereby forming a buffer to protect the charging tank. In addition, compared with the booster cylinder 6, the stroke of the servo cylinder 2 is easier to control, and the pressure applied when sealing the charging tank is easier to accurately control, further avoiding damage to the charging tank.

[0044] refer to Figure 3 Combined with Figure 1 , Figure 3 This is a schematic structural diagram of a C-shaped seat according to an embodiment of the present invention.

[0045] The C-shaped base 1 includes an upper mounting platform 10 and a lower mounting platform 11, which are connected by two identical C-shaped plates. Of course, the C-shaped base 1 can be formed by welding or screwing corresponding plates or blocks, or it can be formed as a single piece. The upper mounting platform 10 is used to mount the servo cylinder 2. The upper mounting platform 10 has a through hole for the servo cylinder 2's pressure rod 20 to pass through, so that the lower end of the pressure rod 20 is located at the bottom of the mounting platform. The lower mounting platform 11 is used to mount the pad 4 and cylinder 6. The pad 4 is placed on the upper surface of the lower mounting platform 11 and is connected to the lower mounting platform 11 by bolts or screws. The cylinder 6 is located at the bottom of the lower mounting platform 11.

[0046] Specifically, bolts or screws are used to connect the cylinder 6 to the cylinder fixing plate 62, and two fixed optical axes 61 are fixedly connected to the cylinder fixing plate 62. The upper end faces of the two fixed optical axes 61 are provided with threaded holes. The two fixed optical axes 61 are connected to the lower mounting platform 11 by screws, thereby stably connecting the cylinder 6 to the lower part of the lower mounting platform 11.

[0047] A through slot 12 is also provided between the upper mounting platform 10 and the lower mounting platform 11, through which a transmission mechanism for conveying the sealing cover can be arranged. The transmission mechanism conveys the sealing cover to the bottom of the clamping jaw 30 for grasping by the clamping jaw 30. The transmission mechanism for conveying the sealing cover here is not a component of the pressing device of the utility model, and therefore will not be described in detail here and can be regarded as existing technology.

[0048] refer to Figure 4 , Figure 4 This is a diagram showing the position relationship between the cylinder and the cylinder fixing plate.

[0049] A circular hole is formed on the lower mounting platform 11, and a center hole is formed in the middle of the cushion block 4, which passes through both ends of the cushion block 4. A lifting optical shaft 5 is inserted into the circular hole of the lower mounting platform 11 and the center hole of the cushion block 4. The lower end of the lifting optical shaft 5 is connected to the floating joint 60, which is connected to the output end of the cylinder 6. The upper end of the lifting optical shaft 5 is located in the center hole of the cushion block 4. When a charging tank is placed on the cushion block 4 and a sealing cap is press-fitted onto the charging tank, the cylinder 6 first lifts the charging tank upward to a certain height. The clamping jaws 30 then grasp the sealing cap and press it down to the tank opening of the charging tank through the capping die 31. Since the charging tank has been raised to a certain height in advance, the cylinder 6 cooperates with the charging tank to fall back during the downward pressing of the capping die 31, forming a buffer process, thereby protecting the charging tank and preventing damage to the charging tank.

[0050] refer to Figure 5 , Figure 5 Schematic diagram of the connection between the positioning core block and the spacer block.

[0051] To ensure the stability of the charging canister placed on the cushion block 4, a positioning core block 40 is also connected to the cushion block 4. One end surface of the positioning core block 40 is provided with a step protruding from its end face. The size of this step is adapted to the central hole in the middle of the cushion block 4. The step is inserted into the central hole, thus connecting the positioning core block 40 and the cushion block 4 together. The center of the positioning core block 40 also has a large-diameter hole extending through both end surfaces. The diameter of the large-diameter hole is larger than that of the central hole in the cushion block 4, so that the charging canister can be placed in the large-diameter hole and prevented from tipping or tilting.

[0052] Furthermore, a flange linear bearing 50 is provided on the lifting optical axis 5, and the flange linear bearing 50 is provided on the side of the lifting optical axis 5 close to the pad 4. The end of the flange linear bearing 50 with the flange is connected to the lower mounting platform 11. The lifting optical axis 5 can achieve smooth sliding with the lower mounting platform 11 and the pad 4 through the flange linear bearing 50.

[0053] refer to Figure 6 , Figure 6 Schematic diagram of the arrangement of the press cylinder, capping die and clamping jaws.

[0054] The end of the pressure rod 20 of the servo pressure cylinder 2 is connected to the pressure cylinder joint 21. Both ends of the pressure cylinder joint 21 are flanges. Both flanges are provided with connecting screw holes. The two flanges are respectively threadedly connected to the pressure rod 20 and the pressing cylinder 3 by screws. The pressure cylinder joint 21 is connected to the pressure rod 20 and the pressing cylinder 3 by bolts, which facilitates the connection and disassembly of the pressing cylinder 3 and the pressure rod 20. When the clamping jaws 30 or the pressure cover mold 31 need to be replaced, the pressing cylinder 3 can be directly removed from the pressure rod 20. The bolt connection greatly improves the efficiency of replacing the pressing cylinder 3.

[0055] The pressing cylinder 3 is a hollow cylinder with a screw hole on the upper end face of the cylinder, which is connected to the flange of the cylinder joint 21 by screws. The lower end of the cylinder is fixedly connected to the cover mold 31. When the servo cylinder 2 drives the pressure rod 20 to move downward, the pressing cylinder 3 drives the cover mold 31 to move downward. A plurality of slots are provided on the side wall of the press cylinder 3, which penetrate the inside and outside of the side wall. At the same time, a pneumatic drive is arranged in the hollow interior of the press cylinder 3. The pneumatic drive is connected to the clamp 30. The clamp 30 is U-shaped. One end of the clamp 30 is connected to the pneumatic drive, and the other end passes through the slot on the side wall of the press cylinder 3 and is located in the avoidance groove 311 on the side wall of the capping mold 31. When the pneumatic drive is working, it can drive the clamp 30 to move along the axial direction of the press cylinder 3, thereby grabbing the sealing cover. When the sealing cover is aligned with the tank opening of the charging tank, the servo cylinder 2 drives the capping mold 31 to move downward, thereby pushing the sealing cover grabbed by the clamp 30 out of the tank opening. It should be noted that since the avoidance groove 311 is provided on the side wall of the capping mold 31, the clamp 30 will not hinder the downward movement of the capping mold 31, and the direction in which the avoidance groove 311 is opened is along the axial direction of the capping mold 31.

[0056] In this embodiment, the pneumatic drive component is an MHS3-20D type pneumatic finger cylinder 6, which is fixed inside the press-fitting cylinder 3. When the press-fitting cylinder 3 moves downward, the starting mechanism drive component also moves downward, but the clamping jaw 30 can move axially relative to the press-fitting cylinder 3.

[0057] For further reference, Figure 7 A flange outer ring 41 is also provided on the positioning core block 40, and the tank opening of the loading tank is located inside the flange outer ring 41. When the capping mold 31 is pressed down, the downward movement height of the sealing cover at the tank opening is limited by the flange outer ring 41, so that the sealing cover can not only seal the tank opening well, but also avoid damaging the tank opening.

[0058] Reference again Figure 1A sensor mounting plate 70 is also connected to the C-shaped base 1. A sensor 7 is mounted on this sensor mounting plate 70. This sensor 7 can detect the position of the pressure rod 20 of the servo cylinder 2 and determine the travel distance, thereby providing a basis for optimizing the stroke and pressure of the servo cylinder 2. In this embodiment, the sensor 7 is a through-beam fiber optic sensor 7. This through-beam fiber optic sensor 7 is composed of two optical fibers and two light sources, and has the advantage of high detection accuracy. This through-beam fiber optic sensor 7 is an existing product, and its operating principle will not be described in detail.

[0059] Furthermore, an operating terminal 8 is mounted on the C-shaped base 1. The operating terminal 8 is connected to the servo cylinder 2, the sensor 7, the pneumatic drive, and the cylinder 6, so that operations can be performed through the operating terminal 8. The operating terminal 8 is a touch screen and is connected to a programmable PLC controller, which is connected to the servo cylinder 2, the sensor 7, the pneumatic drive, and the cylinder 6.

[0060] It should be mentioned that, in this embodiment, the models of the servo cylinder 2 , the air cylinder 6 and the sensor 7 are not limited, and in practice, appropriate ones can be selected based on actual needs.

[0061] Of course, the pressing device of the sealing cover of the present invention is not limited to sealing the tank mouth of the filling tank, but can also be used to seal other bottled containers, and use sealing rings to fit parts or products. When the fitting part is a sealing ring, the existing clamping jaws 30 and the pressing cover mold 31 need to be replaced with clamping jaws 30 and the pressing cover mold 31 that match the sealing ring.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
