Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an automatic assembly mechanism of a magnet and a round cover in a gas self-closing valve. Background Art

[0002] Gas is a widely used gas fuel. Due to its flammable, explosive and poisonous properties, leakage can easily cause major safety accidents. Therefore, it is necessary to ensure that the gas entering the gas appliance is kept at a normal pressure so that it can burn fully and stably. At present, a gas self-closing valve is installed in front of the gas appliance to automatically close the valve when overpressure or underpressure occurs to prevent gas leakage.

[0003] For example, the gas self-closing valve disclosed in patent application No. 202320507447.2 includes a valve body, a valve core assembly, an overflow valve, and a ball valve. The valve body includes a lower shell and an upper cover. The lower shell is provided with an inlet and an outlet. The inlet end is connected to the overflow valve, and the outlet end is connected to the ball valve. A valve seat and a valve core assembly are arranged in a chamber formed by the upper cover and the lower shell. The valve seat is provided with a valve port connecting the inlet and the outlet. The valve core assembly includes a red twist, a lifting button, a connecting rod, a diaphragm, a magnet, a slider, and a sealing gasket. The lifting button is arranged on the top of the upper cover. The red twist is arranged in the lifting button and cooperates with it, and the red twist is fixedly connected to the upper end of the connecting rod. The rod of the connecting rod extends into the upper cover and is fixedly connected to the diaphragm sheet. The upper cover and the lower shell are fixed by a riveting ring, and the periphery of the diaphragm sheet forms a clamping seal when the upper cover and the lower shell are fixed. The lower end of the connecting rod is connected by suction with the magnet, and the slider is placed in the valve seat and slides up and down. The magnet is fixedly connected to the upper end of the slider, and the lower end of the slider is connected with a sealing gasket that is closed with the valve port when the slider slides down into place. In the initial state, under the elastic action of the diaphragm sheet, the lower end of the connecting rod is pressed against the magnet and the slider, and the sealing gasket at the lower end of the slider is pressed against the valve port of the valve seat to form a seal, that is, the inlet and outlet of the lower shell are closed; when the connecting rod moves upward, the suction end of the connecting rod drives the magnet and the slider upward, and the sealing gasket of the slider and the valve port of the valve seat are released, and the inlet and outlet of the lower shell are connected.

[0004] Among them, a magnet sleeve (also called a round cover) is set against the upper end of the slider, and the magnet is embedded in the magnet sleeve. The magnet and the magnet sleeve are fixed to the upper end of the slider by screws. The gas self-closing valve is assembled manually, but the gas self-closing valve is relatively small in size, and the various accessories used are also relatively small, so there is a high difficulty in assembly, slow assembly speed, and low production efficiency. Utility Model Content

[0005] The utility model aims at the above problems existing in the prior art, and proposes an automatic assembly mechanism of a magnet and a round cover in a gas self-closing valve, thereby solving the problem of low production efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] An automatic assembly mechanism for magnets and round covers in a gas self-closing valve comprises a workbench, a linear vibrator arranged on the workbench, and a linear conveying guide rail fixed on the linear vibrator and having a feed end and a discharge end. The mechanism is characterized in that the workbench is also provided with a bracket located on one side of the linear vibrator, the upper end of the bracket is connected to a sliding seat, a guide pipe is vertically fixedly connected to the upper edge of the workbench, a rod-shaped pushing piece that can move up and down is provided in the guide pipe, a suction cylinder is fixedly connected to the sliding seat, and a suction piece that can be adsorbed by a magnet is fixedly connected to the lower end of the suction cylinder, the linear conveying guide rail has a shoulder at the port of the discharge end, the sliding seat can be translated from above the guide pipe relative to the bracket to above the discharge end of the linear conveying guide rail, and the sliding seat is also provided with a stripping piece that can move downward and dislodge the magnet adsorbed on the lower end of the suction piece.

[0008] When in use, the feed end of the linear conveyor rail is connected to the vibration plate, and a number of magnets are placed in the guide tube, and the magnets are attracted to each other to form a string. Initially, the sliding seat is in a position where the suction piece is located directly above the guide tube, and the push piece moves upward to expose the topmost magnet outside the upper end of the guide tube. The piston rod of the suction cylinder extends downward to make the suction piece contact with the magnet exposed outside the upper end of the guide tube to form adsorption, and then the sliding seat is translated toward the discharge end of the linear conveyor rail, and the magnet attracted to the lower end of the suction piece is separated from the magnet located below it and attracted to it by the force of translation. After the sliding seat is translated to the discharge end of the linear conveyor rail where the suction piece is located, so that the magnet adsorbed on its lower end is located directly above the round cover at the discharge end of the linear conveyor rail, the stripping piece moves downward to remove the magnet adsorbed on the lower end of the suction piece and press it into the round cover to achieve automatic installation. After that, other clamping mechanisms remove the round cover equipped with the magnet from the discharge end of the linear conveyor rail and proceed to the next process. After the installation is completed, the stripping piece and the suction piece are reset, and then the sliding seat is translated again to the suction piece located directly above the guide tube. Through such a setting, the automatic assembly of the magnet and the round cover is achieved, and the production efficiency is improved.

[0009] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the suction piece is columnar, and the lower end of the suction piece has a matching head. The matching head has a matching part 1 and a matching part 2 from top to bottom. The outer diameter of the matching part 1 gradually decreases from top to bottom, and the outer diameter of the matching part 2 is the same as the minimum outer diameter of the matching part 1.

[0010] The shape of the matching head can just match with the inner hole of the magnet, so that the material suction piece can stably suck up the magnet, thereby improving the reliability of the automatic assembly mechanism of the magnet and the round cover.

[0011] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the upper end of the guide pipe is slightly higher than the linear conveying guide rail.

[0012] The upper end of the guide tube is slightly higher than the linear conveyor rail, which means that after the sliding seat moves horizontally from the upper end of the guide tube to above the discharge end of the linear conveyor rail, the magnet adsorbed on the lower end of the suction piece is very close to the round cover, which also ensures that the stripping piece can accurately press the magnet into the round cover.

[0013] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the stripping piece is plate-shaped and is sleeved outside the suction piece. A stripping cylinder is fixedly connected to the sliding seat, and the stripping piece is fixedly connected to the lower end of the piston rod of the stripping cylinder.

[0014] After the suction piece embeds the adsorbed magnet into the round cover at the discharge end of the linear conveyor rail, the piston rod of the stripping cylinder extends downward and drives the stripping piece to move downward. After the stripping piece abuts against the magnet, the stripping piece can naturally push the magnet downward and separate from the suction piece as it continues to move downward.

[0015] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the number of the stripping cylinders is two, and the two stripping cylinders are located on both sides of the suction cylinder.

[0016] Through such an arrangement, the stripping plate can more stably strip the magnet from the material suction piece.

[0017] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, a slide rail for the sliding seat to slide is arranged laterally on the upper end of the bracket, a translation cylinder is fixed on the bracket, and the sliding seat is fixedly connected to the end of the piston rod of the translation cylinder.

[0018] The sliding seat is moved back and forth between the output end of the linear conveying guide rail and the material guide pipe by extending or retracting the piston rod of the translation cylinder, thereby realizing the unloading of the magnet and the automatic loading of the round cover.

[0019] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, an electric push rod is fixedly connected to the bottom of the workbench, and the pushing piece is the piston rod of the electric push rod, or a pushing cylinder is fixedly connected to the bottom of the workbench, and the pushing piece is the piston rod of the pushing cylinder.

[0020] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the upper end of the guide tube is fixedly connected to a mounting ring, on which a counter-beaming optical fiber sensor is provided. The upper side surface of the mounting ring has relatively arranged protrusions, and two probes of the counter-beaming optical fiber sensor are respectively fixed on the two protrusions.

[0021] By setting the opposing optical fiber sensor, the upward movement of the pusher can be controlled to ensure that two or more magnets are not pushed out of the upper port of the guide tube at one time.

[0022] In the automatic assembly mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, a mounting seat is fixedly connected to the workbench, and the bracket and the linear vibrator are both fixedly connected to the mounting seat.

[0023] The bracket and the branch line vibrator are all fixedly connected to the mounting base, so that the whole installation on the workbench can be realized except for the magnet storage base.

[0024] Compared with the prior art, the automatic assembly mechanism of the magnet and the round cover in the gas self-closing valve realizes the automatic assembly of the magnet and the round cover by arranging the material suction piece, the material stripping piece and the material guide pipe, thereby improving the production efficiency.

DETAILED DESCRIPTION

[0031] 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.

[0032] like Figure 1 and Figure 2As shown, the automatic assembly mechanism of the magnet and the round cover in the gas self-closing valve includes a workbench (not shown in the figure), a linear vibrator 1 arranged on the workbench, and a linear conveying guide rail 2 fixed on the linear vibrator 1 and having a feeding end and a discharging end, the linear conveying guide rail 2 having a feeding trough arranged along its length direction, and the linear conveying guide rail 2 having a stop shoulder 2a at the port of the discharging end. The workbench is also provided with a bracket 3 located on one side of the linear vibrator 1. In this embodiment, a mounting seat 4 is fixedly connected to the workbench, and the bracket 3 and the linear vibrator 1 are both fixedly connected to the mounting seat 4. A sliding seat 5 is connected to the upper end of the bracket 3, and a guide pipe 6 is fixedly connected vertically to the upper edge of the workbench. A rod-shaped pusher 7 that can move up and down is provided in the guide pipe 6. A suction cylinder 8 is fixedly connected to the sliding seat 5, and a suction member 9 that can be adsorbed by a magnet 18 is fixedly connected to the lower end of the suction cylinder 8. The sliding seat 5 can be translated relative to the bracket 3 from the upper side of the guide pipe 6 to the upper side of the discharging end of the linear conveying guide rail 2. Specifically, the upper end of the material guide pipe 6 is slightly higher than the linear conveying guide rail 2, and a slide rail 10 for sliding the sliding seat 5 is horizontally arranged on the upper end of the bracket 3. A translation cylinder 11 is fixed on the bracket 3, and the sliding seat 5 is fixedly connected to the piston rod end of the translation cylinder 11.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the suction piece 9 is columnar and is an iron piece. The lower end of the suction piece 9 has a matching head 9a. The matching head 9a has a matching part 1 9a1 and a matching part 2 9a2 from top to bottom. The outer diameter of the matching part 1 9a1 gradually decreases from top to bottom, and the outer diameter of the matching part 2 9a2 is the same as the minimum outer diameter of the matching part 1 9a1. The sliding seat 5 is also provided with a stripping piece 12 that can move downward and remove the magnet 18 adsorbed on the lower end of the suction piece 9 downward. The stripping piece 12 is plate-shaped and sleeved outside the suction piece 9. The sliding seat 5 is fixedly connected with a stripping cylinder 13, and the stripping piece 12 is fixedly connected to the lower end of the piston rod of the stripping cylinder 13. Among them, the number of stripping cylinders 13 is two, and the two stripping cylinders 13 are located on both sides of the suction cylinder 8. In practice, except for the suction piece 9, the rest of the materials that will contact the magnet 18 are made of materials that will not form adsorption with the magnet 18, such as aluminum alloy.

[0034] Furthermore, if Figure 1 , Figure 2 and Figure 4As shown, an electric push rod 14 is fixedly connected to the bottom of the workbench, and the pusher 7 is the piston rod of the electric push rod 14. In addition to the electric push rod 14, a pusher cylinder can also be fixedly connected to the bottom of the workbench, and the piston rod of the pusher cylinder can be used as the pusher 7. A mounting ring 15 is fixedly connected to the upper end of the material guide tube 6. The mounting ring 15 is specifically in the shape of an open ring. In practice, screws can be set at the opening of the mounting ring 15. After the mounting ring 15 is put on the upper end of the material guide tube 6, the screws are tightened to tighten the opening and fix the mounting ring 15 to the material guide tube 6. A counter-beam optical fiber sensor 16 is provided on the mounting ring 15. The upper side surface of the mounting ring 15 has relatively arranged protrusions 15a, and the two probes of the counter-beam optical fiber sensor 16 are respectively fixed on the two protrusions 15a.

[0035] like Figure 5 As shown, when in use, the feed end of the linear conveying guide 2 is connected to the vibration plate and the circular cover 17 is sequentially sent to the linear conveying guide 2 by the vibration plate, and a number of magnets 18 are placed in the guide tube 6, and the magnets 18 are mutually adsorbed to form a string. Initially, the sliding seat 5 is in a position where the suction member 9 is located directly above the guide tube 6, and the push member 7 moves upward to expose the topmost magnet 18 outside the upper end of the guide tube 6. After the opposing optical fiber sensor 16 detects the existence of the magnet 18, the electric push rod 14 stops working and the piston rod of the suction cylinder 8 extends downward, so that the mating head 9a of the suction member 9 is inserted into the inner hole of the magnet 18 and forms adsorption. Next, the sliding seat 5 is translated toward the discharge end of the linear conveying guide 2, and the magnet 18 adsorbed on the lower end of the suction member 9 is separated from the magnet 18 located below it and adsorbed with it by the force of the translation.

[0036] After the sliding seat 5 is translated to the discharge end of the suction member 9 at the linear conveying guide rail 2 so that the magnet 18 adsorbed on its lower end is located directly above the round cover 17 at the discharge end of the linear conveying guide rail 2, the piston rod of the stripping cylinder 13 extends downward and drives the stripping member 12 to move downward, and the stripping member 12 removes the magnet 18 adsorbed on the lower end of the suction member 9 downward and presses it into the round cover 17 to achieve automatic installation, and then other clamping mechanisms remove the round cover 17 equipped with the magnet 18 from the discharge end of the linear conveying guide rail 2 and proceed to the next process. After the installation is completed, the stripping member 12 and the suction member 9 are reset, and then the sliding seat 5 is translated again to the suction member 9 located directly above the guide tube 6.

[0037] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
