Description

Technical Field

[0001] This invention belongs to the field of automation technology, specifically relating to an automatic assembly device for AGM exhaust plugs. Background Technology

[0002] During operation, batteries produce hydrogen and oxygen. To ensure proper functioning, these gases must be released through a vent plug. Vent plugs are typically made of plastic and are securely attached to the battery cover. They not only expel gases from the battery, preventing potential hazards, but also seal the battery to prevent air ingress and oxidation of the plates. Vent plugs are usually made of AGM (a type of fiberglass), which offers excellent insulation, heat resistance, corrosion resistance, and high mechanical properties.

[0003] Exhaust plugs generally consist of a plug core and a plug body. In the current technology, exhaust plugs are usually assembled manually, which results in high labor intensity for workers and low assembly efficiency. In order to increase the number of exhaust plugs assembled, more workers need to be hired, resulting in high labor costs. Moreover, the different habits of each person assembling can easily affect the pass rate of exhaust plugs. After the exhaust plugs are assembled, they need to be tested to see if they are qualified. If unqualified products enter the assembly line, it will cause huge economic losses and reputational damage. Summary of the Invention

[0004] This invention provides an automatic assembly device for AGM exhaust plugs, aiming to solve the technical problems of existing technologies where exhaust plugs are assembled manually, resulting in low work efficiency, high labor intensity, and inconsistent manual processing methods that cannot guarantee the product qualification rate. This leads to unqualified products entering the assembly line, causing huge economic losses and reputational damage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic assembly device for AGM exhaust plugs is provided, comprising a frame, a conveying assembly having a reciprocating degree of freedom along a first preset path, and a flipping assembly disposed on the feeding side of the conveying assembly. The automatic assembly device for AGM exhaust plugs further includes a feeding assembly, a pressing assembly, and a heat sealing assembly arranged sequentially along the first preset path. The feeding assembly is located above the flipping assembly and has a sliding part that reciprocates along the first preset path. The sliding part is used to grip the plug core. The pressing assembly and the heat sealing assembly are located above the conveying assembly. The pressing assembly has a pressing part that moves in the vertical direction, and the heat sealing assembly has a heat sealing part that moves vertically.

[0006] The flipping assembly includes a support, above which is provided a material discharge trough for docking with the feeding assembly, a guide channel on the side of the material discharge trough facing the pressing assembly, and an assembly position docking with the discharge side of the guide channel. The flipping assembly also includes a top-loading cylinder, which has a lifting part extending into the material discharge trough. The lifting part is used to lift the core so that the core slides along the guide channel into the core body in the assembly position to form a semi-finished product. The conveying assembly has a clamping part, which is used to drive the semi-finished product to move along a first preset path. The clamping part has a first state in the assembly position, a second state in which the semi-finished product is moved to a position directly below the pressing assembly, and a third state in which the semi-finished product is directly below the heat-sealing assembly.

[0007] In one possible implementation, the AGM exhaust plug automatic assembly device further includes a feeding assembly comprising a vibratory feeder and a conveying channel connecting the assembly position and the vibratory feeder.

[0008] In one possible implementation, the feeding assembly further includes a mounting bracket disposed on the outer periphery of the vibratory feeder, the inner wall of which is covered with sound-insulating cotton.

[0009] In one possible implementation, the AGM exhaust plug automatic assembly device further includes a feeding assembly located on the inlet side of the feeding assembly. The feeding assembly includes a conveyor belt extending along a first preset path, with the outlet side of the conveyor belt located below the inlet side of the feeding assembly for conveying the plug core.

[0010] In one possible implementation, a mounting platform is provided above the support, and the feeding assembly includes a drive cylinder fixed to the mounting platform and a feeding cylinder fixed to the end of the piston rod of the drive cylinder. The feeding cylinder forms the sliding part, and the feeding cylinder is provided with a telescopic part that moves in the vertical direction, and two clamping plates that are slidably engaged with the telescopic part. The two clamping plates are used to move closer to each other to grip the stud.

[0011] In one possible implementation, the mounting platform is provided with a slide rail extending along a first preset path, and the bottom of the feeding cylinder is provided with a slider that slides in cooperation with the slide rail.

[0012] In one possible implementation, the frame is provided with a track extending along a first preset path, and the conveying assembly includes:

[0013] The first cylinder is mounted on the frame and its axis is parallel to the first preset path;

[0014] The slide block is fixed to the piston rod of the first cylinder and slides in cooperation with the slide rail;

[0015] The first gripping cylinder is fixedly mounted on the slide block;

[0016] The second gripping cylinder is fixed to the slide and is spaced apart from the first gripping cylinder on the side away from the flipping assembly.

[0017] The first gripping cylinder and the second gripping cylinder constitute the clamping part. The first gripping cylinder is used to grip the semi-finished product located at the assembly position and move it below the pressing component. The second gripping cylinder is used to grip the semi-finished product located below the pressing component and move it below the heat sealing component. Both the first gripping cylinder and the second gripping cylinder have a locking part that moves along a second preset path. The locking part has a slot for accommodating the semi-finished product. The second preset path is parallel to the horizontal direction and perpendicular to the first preset path.

[0018] In one possible implementation, the AGM exhaust plug automatic assembly device further includes a positioning component, the positioning component comprising:

[0019] The third cylinder is connected to the frame and is located below the heat sealing assembly. The third cylinder is opposite to the second gripping cylinder, and the axis of the third cylinder is parallel to the axis of the second gripping cylinder.

[0020] The mounting plate is fixed to the piston rod of the third cylinder. The mounting plate has an opening on the side opposite to the third cylinder. The mounting plate is used to engage with the snap-fit ​​part on the second gripping cylinder in the third state to clamp the semi-finished product.

[0021] In one possible implementation, the frame is further provided with two opposing clamps, the surfaces of which are parallel to the first preset path, and the two clamps together form a slide for the semi-finished product to pass through.

[0022] In one possible implementation, the frame is provided with a second cylinder, and the piston rod of the second cylinder is provided with a stop bar that slides along a second preset path. The stop bar is used to block the assembly position on the side opposite to the guide channel.

[0023] The automatic assembly device for AGM exhaust plugs provided by this invention, compared with the prior art, can continuously complete the flipping of the plug core, the preliminary assembly of the plug core and plug body to form a semi-finished product, the clamping of the semi-finished product, and the heat sealing connection between the plug core and plug body. In this process, the various processes cooperate closely, realizing the efficient assembly of exhaust plugs, reducing the labor intensity of workers, and saving labor costs. The parameters of the clamping component and the heat sealing component are fixed, which can ensure that the parameters of each semi-finished product assembly process are the same (e.g., clamping force, heat sealing temperature), thereby ensuring the consistency of the exhaust plugs in the assembly process and ensuring the pass rate of the exhaust plugs.

[0040] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0041] In this embodiment, each pneumatic component (e.g., cylinder) is equipped with two reed switches, which control the start and stop of the pneumatic component. Each pneumatic component is connected to a PLC electrical control system, which controls the start sequence of each pneumatic component through a solenoid valve. When the plug core moves to the AGM exhaust plug automatic assembly device of this application after the previous process is completed, the bottom surface of the plug core faces up and the top surface faces down.

[0042] Please refer to the following: Figures 1 to 8 The automatic assembly device for AGM exhaust plugs of the present invention will be described. The automatic assembly device for AGM exhaust plugs includes a frame 10, a conveying assembly 20 having a reciprocating degree of freedom along a first preset path, and a tilting assembly 30 disposed on the feeding side of the conveying assembly 20. The automatic assembly device for AGM exhaust plugs also includes a feeding assembly 40, a pressing assembly 11, and a heat sealing assembly 12 arranged sequentially along the first preset path. The feeding assembly 40 is located above the tilting assembly 30 and has a sliding part 41 that reciprocates along the first preset path. The sliding part 41 is used to grip the plug core. The pressing assembly 11 and the heat sealing assembly 12 are located above the conveying assembly 20. The pressing assembly 11 has a pressing part 111 that moves in the vertical direction, and the heat sealing assembly 12 has a heat sealing part 121 that moves vertically. The tilting assembly 30 includes a support 31. Above the seat 31 is a material drop trough 32 for docking with the feeding assembly 40, a guide channel 33 on the side of the material drop trough 32 facing the pressing assembly 11, and an assembly position 34 docking with the discharge side of the guide channel 33. The flipping assembly 30 also includes a top material cylinder 35, which has a lifting part 351 extending into the material drop trough 32. The lifting part 351 is used to lift the core so that the core slides along the guide channel 33 into the core body in the assembly position 34 to form a semi-finished product. The conveying assembly 20 has a clamping part 21, which is used to drive the semi-finished product to move along a first preset path. The clamping part 21 has a first state in the assembly position 34, a second state in which the semi-finished product is moved to the position directly below the pressing assembly 11, and a third state in the position directly below the heat sealing assembly 12.

[0043] Specifically, the pressing assembly 11 is a pressing cylinder, and the piston rod of the pressing cylinder forms a pressing part 111. A column 112 is fixed on the piston rod of the pressing cylinder to facilitate the pressing of the semi-finished product. The heat sealing assembly 12 includes a heat sealing cylinder, and a heating coil 122 is provided on the piston rod of the heat sealing cylinder. The piston rod of the heat sealing cylinder and the heating coil 122 form a heat sealing part 121. After the semi-finished product is pressed by the pressing assembly 11, the conveying assembly 20 places the semi-finished product directly below the heat sealing assembly 12. The piston rod of the heat-sealing cylinder drives the heating coil 122 to heat the connection between the plug core and the plug body, so that the plug core and the plug body are bonded together after reaching a viscous state, thereby completing the assembly of the exhaust plug; the piston rod of the heat-sealing cylinder is also equipped with a thermocouple, which detects the heating temperature of the heating coil 122. The thermocouple and the heating coil 122 are respectively connected to a temperature controller, which controls the heating temperature of the heating coil 122; the piston rod of the top material cylinder 35 forms the lifting part 351.

[0044] Optionally, the four bottom corners of the frame 10 are equipped with bolt adjustment structures. The nuts of the bolts are connected to the bottom of the frame 10. By rotating the nuts, the height of the four corners of the frame 10 can be adjusted to keep the frame 10 level.

[0045] The automatic assembly device for AGM exhaust plugs provided by this invention operates as follows: the sliding part 41 picks up the plug core and moves along a first preset path, placing the plug core into the material drop groove 32 of the support 31. After the plug core falls into the material drop groove 32, it is positioned above the lifting part 351 of the top-loading cylinder 35. The lifting part 351 of the top-loading cylinder 35 moves upward to lift the plug core, causing it to fall out of the material drop groove 32 and slide along the guide channel 33. During this process, the bottom surface of the plug core slides forward on the guide channel 33. When it reaches the bottom of the guide channel 33, the bottom surface of the plug core falls downward into the assembly position 3. A semi-finished product is formed inside the plug body in position 4. At this time, the clamping part 21 of the conveying component 20 is in the first state, which drives the semi-finished product from the assembly position 34 to move along the first preset path to the underside of the pressing component 11. The pressing part 111 moves downward to press the semi-finished product. After the semi-finished product is pressed, the clamping part 21 continues to clamp the semi-finished product and moves the semi-finished product from the underside of the pressing component 11 to the underside of the heat sealing component 12. The heat sealing part 121 moves downward to heat seal the semi-finished product, thereby completing the assembly of the exhaust plug. The above steps are repeated to complete the batch assembly of the exhaust plug.

[0046] The automatic assembly device for AGM exhaust plugs provided by this invention, compared with the prior art, can continuously complete the flipping of the plug core, the preliminary assembly of the plug core and plug body to form a semi-finished product, the clamping of the semi-finished product, and the heat sealing connection between the plug core and plug body. In this process, the various processes cooperate closely, realizing the efficient assembly of exhaust plugs, reducing the labor intensity of workers, and saving labor costs. The parameters of the clamping component 11 and the heat sealing component 12 are constant, which can ensure that the parameters of each semi-finished product assembly process are the same (e.g., clamping force, heat sealing temperature), thereby ensuring the consistency of exhaust plugs in the assembly process and ensuring the pass rate of exhaust plugs.

[0047] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 5 and Figure 8 The structure shown. See also Figure 5 and Figure 8 The AGM exhaust plug automatic assembly device also includes a feeding assembly 50, which includes a vibratory feeder 51 and a conveying channel 52 connecting the assembly position 34 and the vibratory feeder 51. A batch of plugs can be placed into the vibratory feeder 51. When the vibratory feeder 51 is started, the plugs are vibrated and rise along the spiral track inside the vibratory feeder 51. After a series of adjustments, the batch of plugs are arranged in a uniform state with their top surfaces facing upwards as they enter the conveying channel 52 from the vibratory feeder 51. As the vibratory feeder 51 continuously feeds the plugs into the conveying channel 52, it pushes the plugs at the front end to move continuously along the conveying track 16 until the plug at the very front moves into the assembly position 34. The plug core is rotated 180° by the flipping assembly 30 and falls into the plug body, forming a semi-finished product.

[0048] In practice, the conveying channel 52 is set to gradually slope downwards in the direction toward the support 31. The discharge end of the conveying channel 52 is located on one side of the assembly position 34. A baffle can be set on the opposite side of the assembly position 34 and the conveying channel 52 so that when the bolt enters the assembly position 34, it abuts against the baffle, restricting the continued movement of the bolt and ensuring that the bolt core can fall accurately into the bolt body.

[0049] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 5 and Figure 8 The structure shown. See also Figure 5 and Figure 8 The feeding assembly 50 also includes a mounting bracket 53 located on the outer periphery of the vibratory feeder 51, and the inner wall of the mounting bracket 53 is covered with sound-insulating cotton 54. During operation, the vibratory feeder 51 generates noise due to continuous vibration. By setting the sound-insulating cotton 54, the transmission of sound generated by the vibratory feeder 51 during operation can be reduced, thereby playing a role in sound insulation and noise reduction and reducing noise pollution.

[0050] Optionally, each of the four bottom corners of the mounting bracket 53 is equipped with a bolt adjustment structure. The nuts of the bolts are connected to the bottom of the mounting bracket 53. Adjusting the nuts allows for height adjustment of the mounting bracket 53. Rotating the nuts adjusts the height of the four corners of the mounting bracket 53, maintaining the mounting bracket 53 horizontally (e.g., ...). Figure 8 (As shown).

[0051] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 2 and Figure 5 The structure shown. See also Figure 1 , Figure 2 and Figure 5 The AGM exhaust plug automatic assembly device also includes a feeding assembly 60, which is located on the inlet side of the feeding assembly 40. The feeding assembly 60 includes a conveyor belt 61 extending along a first preset path. The outlet side of the conveyor belt 61 is located below the inlet side of the feeding assembly 40 and is used to transport the plug cores. The conveyor belt 61 can connect to the previous process to provide plug cores for the AGM exhaust plug automatic assembly device of this application. The plug cores are spaced along the first preset path on the conveyor belt 61. The conveyor belt 61 drives the plug cores to move towards the support 31. The sliding part 41 of the feeding assembly 40 grabs the plug cores and moves them to the support 31, thereby realizing uninterrupted supply of plug cores. By setting the conveyor belt 61, the efficient operation of the AGM exhaust plug automatic assembly device of this application is ensured.

[0052] Optionally, there is a certain gap between the conveyor belt 61 and the support 31, and a collection box can be set below the gap to facilitate the collection of plug cores that roll off the conveyor belt 61 due to machine failure and the feeding cylinder 43 not having enough time to clamp them.

[0053] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 The structure shown. See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A mounting platform 311 is provided above the support 31. The feeding assembly 40 includes a drive cylinder 42 fixed to the mounting platform 311 and a feeding cylinder 43 fixed to the piston rod end of the drive cylinder 42. The feeding cylinder 43 forms a sliding part 41. The feeding cylinder 43 is provided with a telescopic part 44 that moves in the vertical direction, and two clamping plates 45 that slide in the telescopic part 44. The two clamping plates 45 are used to move closer to each other to grip the plug. The piston rod of the drive cylinder 42 is connected to the feeding cylinder 43, which can drive the feeding cylinder 43 to move towards the conveyor belt 61. When it moves to the foremost end of the plug conveyed by the conveyor belt 61 (see attached diagram), the feeding cylinder 43 is positioned to grip the plug. Figure 1 and Figure 2 When the bolt core is above the feed cylinder 43 (directly below the feed cylinder 43), the feed cylinder 43 is activated, causing the two clamping plates 45 to move closer together to clamp the bolt core. The drive cylinder 42 drives the feed cylinder 43 to move towards the support 31. When the feed cylinder 43 moves above the lifting part 351 of the top feed cylinder 35, the feed cylinder 43 drives the two clamping plates 45 to move away from each other and release the bolt core, thereby completing the automatic feeding of the flipping assembly 30.

[0054] Optionally, the piston rod of the feeding cylinder 43 can be connected to the two clamping plates 45 by a sliding block mechanism. A frame can be fixed to the top of the feeding cylinder 43. The piston rod of the feeding cylinder 43 is slidably engaged with the side of the frame facing the feeding cylinder 43 and extends into the frame. The two clamping plates 45 are slidably connected to the side of the frame away from the feeding cylinder 43. The piston rod of the feeding cylinder 43 extends out and is slidably engaged with the sliding blocks respectively provided on the two clamping plates 45, so that the two clamping plates 45 move closer to each other to clamp the bolt core. The piston rod of the feeding cylinder 43 retracts to move the two clamping plates 45 away from each other to release the bolt core.

[0055] Specifically, each of the two clamping plates 45 has an arc-shaped surface on one side facing the bolt core, which is suitable for the outer circumference of the bolt core, increasing the contact area with the bolt core and improving the stability of the bolt core when the two clamping plates 45 clamp it.

[0056] Optionally, since the position of the feeding cylinder 43 in moving to the position of the conveyor belt 61 to clamp the core is fixed, and the cores are spaced apart on the conveyor belt 61, after the feeding cylinder 43 clamps the previous core, the conveyor belt 61 moves a certain distance so that the next core moves to the clamping position of the feeding cylinder 43, ensuring that the feeding cylinder 43 can clamp and feed continuously.

[0057] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 The structure shown. See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The mounting platform 311 is provided with a slide rail 312 extending along a first preset path, and the bottom of the feeding cylinder 43 is provided with a slider 46 that slides in cooperation with the slide rail 312. During the process of the driving cylinder 42 driving the feeding component 40 to move, the slider 46 cooperates with the slide rail 312, which effectively improves the stability of the feeding cylinder 43 during the clamping process.

[0058] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 3 , Figure 5and Figure 6 The structure shown. See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The conveying assembly 20 includes a first cylinder 22, a slide 23, a first gripping cylinder 24, and a second gripping cylinder 25. The first cylinder 22 is mounted on the frame 10 and its axis is parallel to the first preset path. The slide 23 is fixed to the piston rod of the first cylinder 22 and slides in cooperation with the track 16. The first gripping cylinder 24 is fixed to the slide 23. The second gripping cylinder 25 is fixed to the slide 23 and is spaced apart from the first gripping cylinder 24 on the side opposite to the flipping assembly 30. The cylinder 25 forms a clamping part 21. The first gripping cylinder 24 is used to grip the semi-finished product in the assembly position 34 and move it below the pressing component 11. The second gripping cylinder 25 is used to grip the semi-finished product below the pressing component 11 and move it below the heat sealing component 12. Both the first gripping cylinder 24 and the second gripping cylinder 25 have a latching part 26 that moves along a second preset path. The latching part 26 has a slot 261 for accommodating the semi-finished product. The second preset path is parallel to the horizontal direction and perpendicular to the first preset path.

[0059] Initially, the first gripping cylinder 24 is located in the assembly position 34 and on the side opposite to the feeding component 50. At this time, the second gripping cylinder 25 is directly below the pressing component 11. The piston rod of the first gripping cylinder 24 extends to engage the semi-finished product in the slot 261. After the first cylinder 22 is activated, the slide 23 moves along the track 16 in the direction away from the support 31. The first gripping cylinder 24 grips the semi-finished product and moves it below the pressing component 11. At the same time, the second gripping cylinder 25 grips the semi-finished product below the pressing component 11 and moves it below the heat sealing component 12. Compared with the first gripping cylinder 24 alone completing the switching of the semi-finished product between the assembly position 34, the pressing component 11, and the heat sealing component 12, the device in this embodiment consumes less time for each cycle, shortens the waiting time of the pressing component 11 and the heat sealing component 12, and improves the assembly efficiency of the exhaust plug.

[0060] It should be noted that the distance between the first gripping cylinder 24 and the second gripping cylinder 25 is equal to the distance between the pressing assembly 11 and the heat sealing assembly 12, and also equal to the distance between the assembly position 34 and the pressing assembly 11.

[0061] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 4 , Figure 5 and Figure 7 The structure shown. See also Figure 1 , Figure 4 , Figure 5 and Figure 7The AGM exhaust plug automatic assembly device also includes a positioning component 70, which includes a third cylinder 71 and a mounting plate 72. The third cylinder 71 is connected to the frame 10 and is located below the heat sealing component 12. The third cylinder 71 is opposite to the second gripping cylinder 25, and the axial direction of the third cylinder 71 is parallel to the axial direction of the second gripping cylinder 25. The mounting plate 72 is fixed to the piston rod of the third cylinder 71. An opening 73 is provided on the side of the mounting plate 72 away from the third cylinder 71. The mounting plate 72 is used to engage with the snap-fit ​​part 26 on the second gripping cylinder 25 in the third state to clamp the semi-finished product.

[0062] When the second gripping cylinder 25 moves the compressed semi-finished product to below the heat sealing assembly 12, the piston rod of the third cylinder 71 extends so that the opening 73 on the mounting plate 72 engages with the slot 261 of the second gripping cylinder 25 to clamp and fix the position of the semi-finished product, preventing the semi-finished product from shaking, and ensuring that the heat sealing assembly 12 can smoothly complete the heat sealing process of the semi-finished product and complete the assembly of the exhaust plug.

[0063] Specifically, the slot 261 of the second gripping cylinder 25 is located on the upper part of the semi-finished product, and the opening 73 on the third cylinder 71 is located on the lower part of the semi-finished product. The slot 261 and the opening 73 clamp the semi-finished product from opposite directions to prevent the semi-finished product from shaking when the heat sealing assembly 12 performs heat sealing treatment.

[0064] It should be noted that the central axis of the conveyor belt 61, the central axis between the two clamping blocks of the feeding cylinder 43, the central axis of the support 31, the central axis of the two clamping plates 13, the central axis of the pressing part 111, and the central axis of the heat sealing part 121 are coincident.

[0065] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 and Figure 5 The structure shown. See also Figure 1 and Figure 5 The frame 10 is also equipped with two opposing clamping plates 13, the surfaces of which are parallel to the first preset path. The two clamping plates 13 enclose a slide 14 for the semi-finished product to pass through. During the movement of the semi-finished product driven by the clamping part 21, the semi-finished product slides within the slide 14 formed by the two clamping plates 13. This helps the clamping part 21 to restrict the movement of the semi-finished product. During this process, the clamping part 21 only needs to be able to move the semi-finished product, and it is not necessary to apply excessive clamping force to the semi-finished product to avoid the situation where the clamping force of the clamping part 21 is too large, which may cause the semi-finished product to deform and affect the quality. The assembled exhaust plugs can be arranged in sequence in the part of the slide 14 after the heat sealing component 12, thereby realizing regular material discharge and facilitating the collection of assembled exhaust plugs by the staff.

[0066] Specifically, one of the clamps 13 forms the baffle in the area within the assembly position 34.

[0067] In some embodiments, an improved implementation of the above-described AGM exhaust plug automatic assembly device may employ, as follows: Figure 1 , Figure 3 , Figure 5 and Figure 6 The structure shown. See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The frame 10 is equipped with a second cylinder 15. The piston rod of the second cylinder 15 is equipped with a stop bar 151 that slides along a second preset path. The stop bar 151 is used to block the assembly position 34 on the side away from the guide channel 33.

[0068] The second cylinder 15 is located on the side of the conveying channel 52 away from the support 31 at the discharge end. As the plug continuously slides out of the vibrating plate 51 and into the conveying channel 52, it enters the assembly position 34 through the discharge end of the conveying channel 52. Due to the continuous conveying of the plug by the conveying channel 52, the plug falling into the assembly position 34 will move under the pressure of the subsequent plugs, preventing the plug core from falling into the plug body and affecting the assembly of the exhaust plug. By setting a stop lever 151, when the plug enters the assembly position 34, the piston rod of the second cylinder 15 extends, causing the stop lever 151 to restrict the plug on the side facing away from the support 31, preventing the plug from easily moving within the assembly position 34 and facilitating the direct falling of the plug core into the plug body. After the plug core falls into the plug body and forms a semi-finished product, the piston rod of the second cylinder 15 retracts, allowing the first gripping cylinder 24 to remove the semi-finished product.

[0069] Optionally, a through hole may be provided on the clamping plate 13 facing the second cylinder 15, through which the stop lever 151 can pass. The inner wall of the through hole can support the stop lever 151 and prevent the stop lever 151 from breaking due to excessive pressure.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
