Description

Technical Field

[0001] This invention relates to the field of valve body assembly technology, and in particular to a fire extinguisher valve body filter plug assembly machine. Background Technology

[0002] A portable dry powder fire extinguisher is a portable fire-fighting device suitable for extinguishing initial fires involving solids, liquids, gases, and electrical equipment. It is prohibited for use in metal fires. It consists of a cylinder, a cylinder valve, a spray hose, and other components.

[0003] As an important component of fire extinguishers, the cylinder valve is used to spray powder during fire fighting to prevent the spread of fire. The valve body, as a component of the cylinder valve, needs to be equipped with a pressure gauge to detect the internal pressure of the cylinder. Therefore, the position where the pressure gauge is installed on the side of the valve body needs to be connected to the powder inlet of the valve body. Since there is dry powder inside the cylinder, during internal inflation, the dry powder inside the cylinder may move towards the channel leading to the pressure gauge. In order to prevent the dry powder from rising during inflation, a filter plug needs to be installed at this position. Currently, there is no such assembly equipment on the market, and if manual assembly is used, the efficiency is relatively low. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a fire extinguisher valve filter plug assembly machine.

[0005] This invention is achieved through the following technical solution: The fire extinguisher valve filter plug assembly machine includes a machine base with a turntable at the top. The turntable is controlled to rotate by a drive mechanism. Multiple valve body carriers are evenly arranged along the circumference of the turntable. Along the rotation direction of the turntable, on the outer side of the turntable, there are a valve body feeding mechanism, a valve body correction mechanism, a filter plug pre-compression mechanism, a filter plug compaction mechanism, a visual inspection mechanism, and a feeding mechanism. A valve body correction mechanism includes an inclined pin that can move up and down along its inclined direction. The pin is used to correct the position of the assembly hole of the valve body located in the valve body carrier. The filter plug pre-compression mechanism includes a filter plug feeding mechanism and an inclined pre-compression rod. The filter plug feeding mechanism is used to feed the filter plug, and the pre-compression rod can move up and down along its inclined direction. The pre-compression rod is used to initially press the filter plug into the assembly hole. The filter plug compaction mechanism is used to compact the filter plug into the assembly hole; The visual inspection unit is used to visually inspect the compacted filter plugs; The feeding mechanism is used to feed good and defective products.

[0006] A further provision of this technical solution is that the valve body feeding mechanism includes: The feeding mechanism is used for feeding the valve body; The pushing mechanism, located at the end of the feeding mechanism, is used to push the valve body out. The robotic arm, located on one side of the pushing mechanism, is used to grab and transport the valve body onto the valve body carrier.

[0007] A further provision of this technical solution is that the valve body correction mechanism includes: The positioning component has a guide hole running through it. The movable cavity is located inside the upper part of the positioning component and is connected to the guide hole; The movable part is disposed inside the movable cavity. The ejector pin passes through the movable part and is fixedly connected to the movable part. The top of the ejector pin passes through the positioning part and extends above the positioning part, and the bottom of the ejector pin passes through the positioning part and extends below the positioning part. The spring is located within the movable cavity and at the upper end of the movable component.

[0008] A further feature of this technical solution is that the upper end of the positioning component is also provided with a slot photoelectric switch, which is used to detect whether the ejector pin has completed the correction process.

[0009] A further provision of this technical solution is that the filter plug feeding mechanism includes: The pusher seat has a pusher channel inside. The upper side of the pusher seat has an inlet channel and the upper other side of the pusher seat has a through outlet channel. Both the inlet channel and the outlet channel are set perpendicular to the pusher channel. The preload rod can move in the outlet channel. The feeder has a feed pipe connected to its discharge end via a pipeline, and the feed pipe is connected to the feed channel; The pusher is slidably disposed in the pusher channel, and the surface of the pusher is also perforated with a material receiving hole.

[0010] A further provision of this technical solution is that a guide sleeve is fixed at the lower end of the pusher seat, and a guide channel runs through the guide sleeve, the guide channel being connected to the discharge channel.

[0011] A further provision of this technical solution is that the filter plug compaction mechanism includes an inclined pressing member that can move up and down along its inclined direction.

[0012] A further provision of this technical solution is that the visual inspection mechanism includes a light source and a CCD camera.

[0013] A further provision of this technical solution is that the unloading mechanism includes a good product unloading mechanism and a defective product unloading mechanism, both of which include an unloading robot and an unloading track.

[0014] A further provision of this technical solution is that an anti-detachment mechanism is provided above the turntable. The anti-detachment mechanism includes a horizontally arranged slide cylinder five and an anti-detachment plate connected to the slide cylinder five. The anti-detachment plate is used to press down the valve body and prevent the valve body from detaching from the valve body carrier after the correction process is completed. This invention discloses a fire extinguisher valve filter plug assembly machine, which, compared with the prior art: This technical solution, by setting a valve body correction mechanism, can correct the position of the valve body that has shifted during the feeding process, ensuring that subsequent assembly can proceed smoothly; This technical solution achieves precise positioning and assembly and improves assembly efficiency by setting up a pre-compression and compaction mechanism, which first performs pre-compression and then compaction. This technical solution completes the assembly of valve bodies and filter plugs through automated feeding, correction, pre-compression, compaction, visual inspection, and automated unloading, thereby improving production efficiency.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0031] See Figures 1 to 13As shown, the fire extinguisher valve body filter plug assembly machine includes a machine base with a turntable 10 at its upper end. The turntable 10 is controlled to rotate by a drive mechanism. Multiple valve body carriers 20 are evenly arranged along the circumference of the turntable 10. Along the rotation direction of the turntable 10, a valve body feeding mechanism 30, a valve body correction mechanism 40, a filter plug pre-compression mechanism 50, a filter plug compaction mechanism 60, a visual inspection mechanism 70, and a feeding mechanism 80 are sequentially arranged on the outer side of the turntable 10. The valve body correction mechanism 40 includes an inclined pin 401, which can move up and down along its inclined direction. The pin 401 is used for... The position of the assembly hole of the valve body located in the valve body carrier 20 is corrected; the filter plug pre-compression mechanism 50 includes a filter plug feeding mechanism and an inclined pre-compression rod 509. The filter plug feeding mechanism is used to feed the filter plug, and the pre-compression rod 509 can move up and down along its inclined direction. The pre-compression rod is used to initially press the filter plug into the assembly hole; the filter plug compaction mechanism 60 is used to compact the filter plug into the assembly hole; the visual inspection mechanism 70 is used to perform visual inspection on the compacted filter plug; the unloading mechanism 80 is used to unload good and defective products; wherein, the turntable 10 and the drive mechanism are existing technologies.

[0032] The valve body 11 in this technical solution is referred to. Figure 12 As shown, Figure 12 The valve body 11 shown is inverted. The valve body 11 includes a valve body 110. The lower inner side of the valve body 110 has a powder inlet channel 111, and the upper inner side of the valve body 110 has a powder outlet channel 112. The powder inlet channel 111 and the powder outlet channel 112 are connected. The inner diameter of the powder inlet channel 111 is larger than the inner diameter of the powder outlet channel 112. The upper outer side of the valve body 110 also has a powder spraying channel 113. The powder spraying channel 113 is perpendicular to and connected to the powder outlet channel 112. The upper outer side of the valve body 110 also has a… Mounting base 114 is located next to powder spraying channel 113. Mounting base 114 is used to fix a pressure gauge, which is used to detect the pressure value inside the fire extinguisher cylinder. To detect the pressure value inside the cylinder, mounting base 114 needs to be connected to powder inlet channel 111. An assembly hole 115 is provided on the top edge of the powder inlet channel 111, communicating with mounting base 114. The top edge of the powder inlet channel 111 is an annular inclined surface, meaning the assembly hole 115 is inclined. (Refer to the filter plug in this technical solution.) Figure 13 As shown, the filter plug includes a body and a guide body, which are integrally formed. The body is cylindrical, and the guide body is conical with a flat bottom surface. The guide body mainly serves as a guide during assembly, so that the filter plug can be smoothly inserted into the assembly hole 115. The surface of the filter plug has several filter holes. When assembling the filter plug, the guide body first enters the assembly hole 115 for guidance until the body is pressed into the assembly hole 115.

[0033] In the above technical solution, the valve body 11 is transported to the valve body carrier 20 by the valve body feeding mechanism 30. The valve body carrier 20 has a receiving seat for placing the valve body 11. Then, the turntable 10 drives the valve body 11 to rotate. During the rotation, the valve body feeding mechanism 30 continuously feeds the empty valve body carrier 20. When the turntable 10 moves the valve body 11 to the valve body correction mechanism 40, the ejector pin 401 of the valve body correction mechanism 40 moves downwards to correct the position of the assembly hole 115 of the valve body 11. After correction, the ejector pin 401 returns to the initial position, and the turntable 10 moves the valve body 11 to the filter plug pre-compression mechanism 50. The filter plug pre-compression mechanism 50 feeds the filter plug through the filter plug feeding mechanism, and then the pre-compression rod 509 moves downwards to pre-compress the filter plug into the assembly hole 115 to complete the initial assembly. The preload rod 509 returns to its initial position, and the turntable 10 moves the valve body 11 to the filter plug compaction mechanism 60. The filter plug compaction mechanism 60 completely compacts the filter plug into the assembly hole 115, preventing the filter plug from protruding and completing the assembly process. Then, the turntable 10 moves the valve body 11 to the vision inspection mechanism 70. The vision inspection mechanism 70 performs image inspection on the assembled valve body 11 and provides the image to the processing terminal. The processing terminal analyzes and determines whether it is a good product. If the filter plug is completely pressed into the assembly hole 115, it is a good product; if the filter plug is not completely pressed into the assembly hole 115, it is a defective product. After the analysis and determination are completed, relevant instructions are sent to the unloading mechanism 80 to classify and unload good and defective products. The ejector pin 401 is a round rod structure with a conical bottom and a flat bottom surface.

[0034] See Figure 3 and Figure 4 As shown, the valve body feeding mechanism 30 includes a feeding mechanism for feeding valve bodies 11. This feeding mechanism includes a vibratory feeder and a direct vibratory feeder 304. A feeding track 303 is fixed to the upper end of the direct vibratory feeder 304. Several valve bodies 11 are arranged inside the vibratory feeder. The discharge end of the vibratory feeder is connected to the feeding track 303. The valve bodies 11 are arranged within the vibratory feeder and discharged in an orderly manner according to the correct assembly direction. At the feeding track 303, the valve body 11 moves forward continuously due to the action of the direct vibration feeder 304. The feeding track 303 has a "U"-shaped structure, and a limiting member is provided at the upper end of the feeding track 303. This limiting member is used to limit the top of the valve body 11 to prevent the valve body 11 from leaving the feeding track 303. The pushing mechanism 301 is located at the end of the feeding mechanism and is used to push the valve body 11 out. The pushing mechanism 301 is located at the end of the feeding track 303 of the feeding mechanism. The pushing mechanism 301 includes a slide cylinder 305 and a pushing seat 306 located at its upper end. Cylinder 305 is horizontally positioned. The slide cylinder 305 controls the movement of the pusher seat 306 in the vertical direction of the feeding track 303. The pusher seat 306 has a closed end 307 and a feeding groove 308 on the side near the feeding track 303. The feeding groove 308 supports the valve body 11, and the closed end 307 prevents the valve body 11 from detaching from the feeding track 303. In the initial state, the closed end 307 of the pusher seat 306 is in contact with the end of the feeding track 303 and remains in a blocking state. When feeding is required, the slide cylinder 305... 305 controls the feeding groove 308 to move towards the feeding track 303. Due to the action of the direct vibration feeder 304, it can push the valve body 11 into the feeding groove 308. The bottom of the feeding groove 308 has a bearing plate to support the valve body 11. After the valve body 11 enters the feeding groove 308, the slide cylinder 305 controls the feeding groove 308 to move away from the feeding track 303, while the closed end 307 returns to its initial position to block the valve body 11. The robot arm 302, located on one side of the pushing mechanism 301, is used to grab and transport the valve body 11 to the designated position. On the valve body carrier 20 at the turntable 10, the robot arm 302 is used to grab and transport the valve body 11 located in the feeding groove 308 onto the valve body carrier 20. It is worth noting that the valve body feeding mechanism 30 also includes a displacement sensor, which is used to detect whether the valve body 11 is in place at the pusher seat 306. When the valve body 11 is in place, the displacement sensor sends a signal to the control terminal, which controls the robot arm 302 to work and grab and transport the valve body 11. If the displacement sensor detects that the valve body 11 is not in place, the robot arm 302 does not work.

[0035] See Figure 5 and Figure 6As shown, the valve body correction mechanism 40 includes: a positioning member with a guide hole 404 passing through it; a movable cavity 406 disposed at the upper end of the positioning member and connected to the guide hole 404; a movable member 407 disposed inside the movable cavity 406, with a pin 401 passing through and fixedly connected to the movable member 407, the top of the pin 401 passing through the positioning member and extending above it, and the bottom of the pin 401 passing through the positioning member and extending below it; and a spring 408 disposed inside the movable cavity 406 and located at the upper end of the movable member 407. The valve body correction mechanism 40 also includes a bracket 411 fixed to the machine base. A support frame 411 is located on the outer side of the turntable 10. A second inclined slide cylinder 410 is fixed to the top side of the support frame 411. A positioning component is connected to the second slide cylinder 410, and the second slide cylinder 410 controls the positioning component to move up and down in the inclined direction. The positioning component includes a positioning seat 402, which is rectangular in structure. A mounting groove 403 is recessed in the center of the lower surface of the positioning seat 402. A through hole is formed in the center of the mounting groove 403. A positioning pin sleeve 405 is also fixed inside the mounting groove 403. The movable cavity 406 is located inside the upper end of the positioning pin sleeve 405. The center of the positioning pin sleeve 405 also has a through hole. Through hole two, the movable cavity 406 is connected to through hole two, and through hole one and through hole two constitute the guide hole 404. The guide hole 404 is used to provide a space for the ejector pin 401 to move. The movable part 407 is cylindrical, and through hole three is passed through its center. Through hole three allows the ejector pin 401 to pass through. The ejector pin 401 is fixedly connected to the movable part 407. One end of the spring 408 contacts the top of the movable part 407, and the other end of the spring 408 contacts the mounting groove 403. When the turntable 10 drives the valve body 11 to the working position of the valve body correction mechanism 40, the slide cylinder two 410 of the valve body correction mechanism 40 works to control the ejector pin 401. The needle 401 moves downward in an inclined direction until it extends into the assembly hole 115 of the valve body 11, thereby completing the correction process of the assembly hole 115. After the correction process is completed, the slide cylinder 410 controls the needle 401 to return to its initial position. In addition, in order to allow the needle 401 to leave the valve body 11 smoothly, this technical solution also provides a spring 408. When the needle 401 is corrected, the spring 408 is compressed. When the needle 401 needs to be disengaged, the spring 408 can provide a counter-push force to the moving part 407, so that the needle 401 can leave the valve body 11 smoothly, so as to facilitate the subsequent assembly of the filter plug on the valve body 11.

[0036] See Figure 5 and Figure 6As shown, a slotted photoelectric switch 409 is also provided above the positioning seat 402, which is used to detect whether the ejector pin 401 has completed the correction process; the slotted photoelectric switch 409 is model PM-L45, and a fixing plate is vertically fixed to one side of the positioning seat 402. The slotted photoelectric switch 409 is fixed to the fixing plate and located above the positioning seat 402; because the valve body carrier 20 itself has a certain machining allowance, the receiving seat at the valve body carrier 20 will be larger than the valve body 11 itself. This causes the mounting hole 115 of the valve body 11 to shift left and right when it is placed at the valve body carrier 20. Therefore, it is particularly important to correct the assembly hole 115 by setting the valve body correction mechanism 40. However, it is inevitable that the offset of the assembly hole 115 may be too large, making it impossible to complete the correction process smoothly. Therefore, a slot photoelectric switch 409 is set to detect whether the correction process has been completed. In the above, the top of the ejector pin 401 extends above the positioning member. Therefore, the slot photoelectric switch 409 can detect the running trajectory of the top position of the ejector pin 401. The inability to complete the correction process smoothly means that the bottom of the ejector pin 401 cannot be inserted into the assembly hole 115. During the testing process, the red light on the slot photoelectric switch 409 remains constantly lit. When the correction process is performed, the ejector pin 401 moves downwards in a tilted direction. If the bottom of the ejector pin 401 does not extend into the assembly hole 115, it indicates that the movement stroke of the ejector pin 401 is very small, and the red light on the slot photoelectric switch 409 remains constantly lit, indicating that the correction has not been successfully completed. When the ejector pin 401 completes the correction process, meaning the bottom of the ejector pin 401 extends into the assembly hole 115, it indicates that the movement stroke of the ejector pin 401 is large. At this time, the slot... The photoelectric switch 409 will turn off; therefore, the slot photoelectric switch 409 determines whether the correction process has been completed based on the travel of the ejector pin 401. If the correction process is not completed, the slot photoelectric switch 409 will send a signal to the processing terminal, which will control other subsequent mechanisms not to perform assembly and inspection processes on the valve body 11, and directly determine it as a defective product, which will then be unloaded by the unloading mechanism 80. If the correction process is completed, the slot photoelectric switch 409 will send a signal to the processing terminal, which will then control other subsequent mechanisms to continue the assembly process on the valve body 11.

[0037] See Figure 1 and Figure 7 , Figure 8As shown, the filter plug feeding mechanism includes: a pusher seat 501, which has a pusher channel 502 inside. A feed channel 503 is provided on one side of the upper end of the pusher seat 501, and a through discharge channel 504 is provided on the other side of the upper end of the pusher seat 501. Both the feed channel 503 and the discharge channel 504 are perpendicular to the pusher channel 502. A pre-compression rod 509 can move within the discharge channel 504; a feeder 505, whose discharge end is connected to a feed pipe 506 via a pipe. The feed pipe 506 is connected to the feed channel 503; and a pusher component 507, which is slidably disposed within the pusher channel 502. A receiving hole 508 penetrates the surface of the pusher component 507, and the pusher component 507 has a rectangular structure. The pusher seat 501 is rectangular. The structure includes a non-through feeding channel 503 and a vibratory feeder 505. The vibratory feeder arranges the filter plugs neatly according to the assembly direction and transports them into the feeding channel 503 through the feeding pipe 506. In the initial state, the material receiving hole 508 of the pusher 507 is located directly below the feeding channel 503, with the tapered surface of the filter plug facing down in the feeding channel 503. A mounting plate is fixed to one side of the upper end of the pusher seat 501, located outside the feeding channel 503. A pusher cylinder is fixed to the lower end of the mounting plate, with the piston rod end of the pusher cylinder connected to the pusher 507. Due to the continuous feeding by the feeder 505, the filter plugs accumulate one by one. When pushing is needed again, the pusher cylinder... When the cylinder operates, the pusher 507 moves, causing the filter plug in the receiving hole 508 to move towards the discharge channel 504 until the filter plug is located in the discharge channel 504 (during the pushing process, since the pusher 507 only has the receiving hole 508, the remaining position of the pusher 507 will be blocked by the feeding channel 503 to prevent the filter plug from falling off). Then, the pre-pressing rod 509 operates to push the filter plug. The filter plug feeding mechanism also includes a second bracket 512, which is fixed on the machine base and located outside the turntable 10. A third sliding cylinder 513 is fixed on the top of the second bracket 512. The third sliding cylinder 513 is also connected to the push plate. The third sliding cylinder 513 is in a [missing information - likely a specific orientation or position]. The slide cylinder 513 is tilted and can control the push plate to move up and down in the tilt direction. The push seat 501 is fixedly connected to the push plate, that is, the slide cylinder 513 can control the push seat 501 to move up and down in the tilt direction. The side of the push plate is also fixed with a cylinder 514. The piston rod end of the cylinder 514 is connected to the pre-pressing rod 509. The lower end of the push seat 501 is also fixed with a guide sleeve 510. The guide sleeve 510 has a guide channel 511 through it. The guide channel 511 is connected to the discharge channel 504. Thus, when the filter plug is located in the discharge channel 504, the cylinder 514 starts to work, thereby causing the pre-pressing rod 509 to push the filter plug out of the guide sleeve 510 and pre-press the filter plug into the assembly hole.The specific working process of the filter plug pre-compression mechanism 50 is as follows: the feeder 505 continuously feeds the filter plugs. When the turntable 10 moves the valve body 11 to the position of the filter plug pre-compression mechanism 50, the slide cylinder 513 operates, causing the guide sleeve 510 to contact the outside of the assembly hole. Then, the pusher cylinder operates, transporting the filter plug to the discharge channel 504. Next, the cylinder 514 operates, pushing the filter plug into the assembly hole through the pre-compression component 509 to complete the pre-compression process. It is worth noting that the feeder 505 is existing technology, and those skilled in the art can select it according to actual needs.

[0038] See Figure 9 As shown, the filter plug compaction mechanism 60 includes an inclined pressing member 601, which can move up and down along its inclined direction. The filter plug compaction mechanism 60 also includes a bracket 3 602, which is fixed on the machine base and located outside the turntable 10. An inclined sliding cylinder 4 603 is fixed to the top of the bracket 3 602. The pressing member 601 is connected to the sliding cylinder 4 603. The sliding cylinder 4 603 controls the pressing member 601 to move downwards at an incline, thereby compacting the filter plug into the assembly hole, thus completing the assembly process. The bottom of the pressing member 601 is a cylindrical structure with a diameter larger than that of the filter plug.

[0039] See Figure 10 As shown, the visual inspection mechanism 70 includes a light source 701 and a CCD camera 702; the unloading mechanism 80 includes a good product unloading mechanism 801 and a defective product unloading mechanism 802, both of which include an unloading robot and an unloading track; the light source 701 takes a picture of the CCD camera 702 and then feeds the picture back to the processing terminal, which determines whether the filter plug is compacted. If it is compacted, a signal is fed back and the good product unloading mechanism 801 is controlled to unload the good product; if it is not compacted, a signal is fed back and the defective product unloading mechanism 802 is controlled to unload the defective product. The above visual inspection and unloading are existing technologies, and those skilled in the art can select them according to actual needs.

[0040] See Figure 11As shown, an anti-detachment mechanism 90 is also provided above the turntable 10. The anti-detachment mechanism 90 includes a horizontally arranged slide cylinder 5 901 and an anti-detachment plate 902 connected to the slide cylinder 5 901. The anti-detachment plate 902 is used to press down the valve body 11 and prevent the valve body 11 from detaching from the valve body carrier 20 after the correction process is completed. The anti-detachment mechanism 90 does not contact the turntable 10, that is, the rotation of the turntable 10 will not drive the anti-detachment mechanism 90 to rotate. The anti-detachment plate 902 has an arc-shaped notch on the side near the valve body carrier 20. The anti-detachment mechanism 90 is only used for the valve body correction mechanism 40. Since the ejector pin 401 of the valve body correction mechanism 40 is used to correct the assembly hole, The ejector pin 401 will extend into the assembly hole. Therefore, there is a possibility that the ejector pin 401 may not be able to detach from the valve body 11. To avoid this situation, when the assembly hole is corrected for the valve body 11, the slide cylinder 901 operates to control the anti-detachment plate 902 to move above the valve body 11. The anti-detachment plate 902 does not contact the valve body 11. When the ejector pin 401 is stuck in the assembly hole and needs to move the valve body 11 away from the valve body carrier 20, the anti-detachment plate 902 can provide a longitudinal force to the valve body 11 to prevent the valve body 11 from detaching from the valve body carrier 20. Its main function is to prevent this. After the correction process is completed, the slide cylinder 901 controls the anti-detachment plate 902 to return to its initial position.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
