Description

An automatic steam pump assembly machine Technical Field

[0001] This invention relates to the field of pump assembly machines, and more particularly to an automatic steam pump assembly machine. Background Technology

[0002] A steam mop is a household or commercial cleaning device that uses high-temperature, high-pressure steam to clean floors and surfaces. Its core purpose is to soften stains and kill bacteria with high-temperature steam, achieving efficient and environmentally friendly cleaning without relying on chemical cleaning agents.

[0003] The steam pump is the core power component of steam cleaning equipment, which includes steam mops, steam cleaners, and steam irons. The steam pump is responsible for drawing clean water from the water tank to the heating module, heating it to generate high-temperature and high-pressure steam, and then stably delivering it to the nozzle or working end of the equipment to provide power support for cleaning and ironing, ensuring that the steam is continuously and stably ejected. For example, the cleaning function of a steam mop relies on the steam pump to provide stable high-temperature and high-pressure steam.

[0004] The assembly quality of a steam pump directly determines the sealing performance, water output stability, and service life of the entire steam cleaning equipment. Steam pump assembly is generally characterized by numerous parts, intricate processes, and high requirements for sealing and coaxiality. Traditionally, steam pumps are mainly assembled manually. Components such as the pump casing, nozzles, and base cover are all manually loaded, aligned, pressed, and inspected. Manual assembly of steam pumps heavily relies on skilled operators, and operator fatigue and variations in operation directly affect the yield rate. The workpieces (steam pumps) are frequently subject to quality risks such as bumps, omissions, and misassemblies. This results in low assembly efficiency, low assembly accuracy, poor assembly results, high labor intensity for workers, and high labor costs for enterprises, making it difficult to meet the demands of large-scale, high-quality production.

[0005] To reduce labor intensity and improve assembly efficiency, some semi-automatic steam pump assembly machines have emerged on the market. However, these machines can only assemble certain parts of the steam pump assembly process and cannot automate the entire assembly process on a single machine. This results in fragmented processes, time-consuming workflows, and long assembly cycles for individual steam pumps. Furthermore, current semi-automatic steam pump assembly machines typically use traditional methods: a pneumatic cylinder drives two movable grippers to clamp O-rings, a pneumatic gripper grips the bottom cover, and a robotic arm to collect the finished pump. This leads to O-ring distortion, bottom cover deformation, and potential damage to the workpiece surface from the movable grippers and pneumatic grippers. The use of a robotic arm for unloading the finished pump results in high equipment costs, complex structure, and high maintenance costs. In addition, the fragmented processes cause workpiece misalignment during workflow and assembly, affecting the alignment accuracy of subsequent stations. This leads to problems such as nozzle misalignment, O-ring distortion, and bottom cover deformation resulting in inadequate sealing during steam pump assembly. These machines cannot meet the requirements of large-scale, high-speed, and automated production. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By installing a circulating conveying mechanism, a pump housing oiling mechanism, a spring assembly mechanism, a first O-ring expansion mechanism, a first O-ring feeding mechanism, a piston feeding mechanism, a first O-ring assembly mechanism, a piston assembly mechanism, a bottom cover assembly mechanism, a pump housing tilting mechanism, a second O-ring feeding mechanism, a second O-ring expansion mechanism, a second O-ring assembly mechanism, a first longitudinal fixing mechanism, a nozzle assembly mechanism, a second longitudinal fixing mechanism, and a finished product guiding mechanism at the top of the casing, the present invention can achieve the function of fixing each pump housing through the circulating conveying mechanism. The steam pump components on the positioning assembly are positioned. The pump housing oiling mechanism performs single or multiple oil spraying lubrication treatments on the pump housing before piston assembly, as needed. The spring assembly mechanism enables fully automatic control of the spring guide to sequentially assemble springs on the pump housings of each pump housing positioning assembly on the track circulation line. The first O-ring feeding mechanism, the first O-ring expansion mechanism, and the first O-ring assembly mechanism work together to automate the feeding, expansion, and fitting of the expanded first O-ring onto the piston. The piston feeding mechanism and the piston assembly mechanism work together to automatically feed the piston. The pump casing assembly mechanism automatically assembles the bottom cover of the pump casing, while the pump casing flipping mechanism automatically flips and positions the pump casing after the bottom cover is installed. The second O-ring feeding mechanism, second O-ring expansion mechanism, and second O-ring assembly mechanism work together to automatically feed, convey, enlarge, and assemble the enlarged second O-rings onto the nozzle connector of the pump casing. The nozzle assembly mechanism automatically feeds, conveys, presses, positions the nozzle cap before installation, and assembles the nozzle onto the pump casing. Furthermore, it uses a finished product guiding mechanism instead of a robotic arm. Finished products are collected and unloaded, enabling automated assembly of multiple different processes for steam pumps on a single machine. This avoids transferring workpieces between different assembly machines, resulting in high assembly precision, high assembly efficiency, good assembly effect, and high yield of finished products. This addresses the problems of low assembly efficiency, low assembly precision, poor assembly effect, low yield, and high assembly cost caused by the current semi-automatic steam pump assembly machine, which suffers from dispersed processes, time-consuming workflow, long assembly cycle of a single steam pump, nozzle eccentricity during assembly, O-ring distortion, and inadequate sealing due to bottom cover deformation.

[0019] 2. By designing the structure of the first O-ring assembly mechanism and the second O-ring assembly mechanism, the O-ring clamping component in each O-ring assembly mechanism clamps the corresponding ring part of the O-ring by cooperating with a fixed clamping finger and an adjacent movable clamping finger. This avoids the O-ring from changing shape and solves the problem that the current semi-automatic steam pump assembly machine, which uses a traditional clamping finger drive device to drive two movable clamping fingers to approach each other to clamp the O-ring, is prone to O-ring changing shape.

[0020] 3. By designing the structure of the bottom cover assembly mechanism, the bottom cover pressing mold head of the bottom cover assembly mechanism uses vacuum to pick up the bottom cover, which avoids deformation of the bottom cover and achieves precise positioning, thereby greatly improving the assembly efficiency. It effectively solves the problem that the current semi-automatic steam pump assembly machine, which uses pneumatic grippers to pick up the bottom cover, is prone to deformation.

The number of first positioning components 23 and second positioning components 25 are equal and they are symmetrically arranged.

[0050] By adopting the above technical solution, the track circulation line 21 drives one or more pump housing positioning components 22 to circulate and convey. When each pump housing positioning component 22 is synchronously conveyed to the next station, the fixture limiting mechanism 24 laterally limits the corresponding pump housing positioning component 22. The first positioning component 23 and the second positioning component 25 on both sides of each pump housing positioning component 22 jointly center and position it, thereby realizing the positioning of the steam pump components on each pump housing positioning component 22 and ensuring the accuracy and quality of steam pump assembly.

A fixture seat 223 is mounted on the top of both the first slider 221 and the second slider 222. A positioning hole 224 is provided at the center of the top of the fixture seat 223. The positioning hole 224 is used to support the pump housing 2206 and position the pump housing 2206. A first positioning block 225 and a second positioning block 226 are sequentially mounted on the fixture seat 223 along the conveying direction of the track circulation line 21.

The contour groove 235 of the limiting fork plate 233 contacts the outer periphery of the pump housing 2206 to position the pump housing 2206. The limiting fork plates 233 of the first positioning assembly 23 and the second positioning assembly 25 push the pump body 2206 together to position and fix the pump body 2206, ensuring the smooth progress and quality of the subsequent steam pump assembly.

[0054] In this embodiment, the structure of the second positioning component 25 is the same as that of the first positioning component 23. The fork drive device 234 is preferably configured as a cylinder.

[0055] Referring to FIG5, the fixture limiting mechanism 24 includes a first fixture transmission assembly 241 and a second fixture transmission assembly 242 mounted side-by-side on the top of the chassis 1 along the conveying direction of the track circulation line 21.

The first jig transmission assembly 241 positions the corresponding pump housing positioning assembly 22, and the second jig transmission assembly 242 positions the corresponding pump housing positioning assembly 22. The first jig transmission assembly 241 and the second jig transmission assembly 242 achieve synchronous positioning of the corresponding pump housing positioning assembly 22 on the track circulation line 21, ensuring the accuracy and consistency of the positioning of the pump housing positioning assembly 22.

[0060] Referring to Figure 9, the pump housing oiling mechanism 4 includes an oil spray mounting bracket 40 mounted on the top of the housing 1. A slide plate drive device 41 is mounted on the oil spray mounting bracket 40. One or more first linear guide rails 42 are mounted longitudinally on one side of the oil spray mounting bracket 40. A third slider 43 is slidably mounted on each first linear guide rail 42. An oil spray slide plate 44 is mounted on each third slider 43.

[0061] By adopting the above technical solution, the slide plate drive device 41 drives the oil injection slide plate 44 to move up and down along the first linear guide rail 42, thereby driving the oil injector 48 to move up and down. The oil injector 48 moves downward and extends into the pump housing 2206. The oil pump 46 supplies oil to the oil injector 48 and sprays the oil onto the inner wall of the pump housing 2206. The slide plate drive device 41 drives the oil injector 48 to move back and forth once or multiple times within the pump housing 2206 as needed to spray oil onto the pump housing 2206, thereby automatically lubricating the pump housing 2206 before the piston is assembled.

The stop pin 501 of the first spring blocking assembly 55 is inserted into the spring conduit 54 to reset and prepare to block the second spring 502. The stop pin 501 of the second spring blocking assembly 56 is withdrawn from the spring conduit 54 to... The second spring 502 is released, and the stop pin 501 of the first spring blocking assembly 55 blocks the second spring 502 in the spring guide tube 54 to fix it.

The top of the fourth mounting plate 84 is equipped with a pusher plate drive device 802. The output end of the pusher plate drive device 802 is fixedly connected to the piston pusher plate 80. The pusher plate drive device 802 drives the piston pusher plate 80 to push the piston along the feed chute 87 and position it at the end of the feed chute 87, realizing fully automatic feeding and positioning of the piston on the piston rail 85. The piston feeding efficiency is high and the piston positioning is accurate. In this embodiment, the pusher plate drive device 802 is preferably set as a cylinder.

[0068] Referring to Figure 13, the first O-ring expansion mechanism 7 includes an expansion base frame 71 mounted on the top of the chassis 1. A fifth mounting plate 72 is mounted on the top of the expansion base frame 71. Four connecting rods 73 are mounted longitudinally on the bottom surface of the fifth mounting plate 72. The four connecting rods 73 are arranged in a matrix. The bottom ends of the four connecting rods 73 are connected to a push seat drive device 74. A first push seat guide hole 75 is provided in the center of the fifth mounting plate 72. The first push seat guide hole 75 penetrates the top and bottom surfaces of the fifth mounting plate 72. A push seat 76 is slidably mounted in the first push seat guide hole 75. The bottom of the push seat 76 is connected to the push seat. The output end of the drive device 74 is fixedly connected. The internal shape of the first pusher guide hole 75 is adapted to the outer circumferential shape of the pusher 76. The pusher drive device 74 drives the pusher 76 to slide up and down within the first pusher guide hole 75. The top of the fifth mounting plate 72 is equipped with an expansion guide plate 77. The bottom center of the expansion guide plate 77 is recessed with a second pusher guide hole 78. The internal shape of the second pusher guide hole 78 is adapted to the outer circumferential shape of the pusher 76, and the second pusher guide hole 78 is vertically aligned with the first pusher guide hole 75. The expansion guide plate 77 is provided with three or more expansion guide grooves 79, each expanding... The expansion guide grooves 79 are evenly distributed at equal angles around the center of the expansion guide plate 77. Each expansion guide groove 79 is connected to the second push seat guide hole 78. Each expansion guide groove 79 is equipped with an expansion block 70 and a second elastic element 701. The expansion block 70 slides in the corresponding expansion guide groove 79. The second elastic element 701 abuts against the ends of the expansion block 70 and the expansion guide groove 79 away from the center of the expansion guide plate 77. Each second elastic element 701 pushes a corresponding expansion block 70 to move towards the center of the expansion guide plate 77. The top of the end of each expansion block 70 near the center of the expansion guide plate 77 is upward. The convex integral molding is provided with a buckle plate 702. Each expansion block 70 has a first chamfered surface 703 at the bottom of one end opposite the center of the expansion guide plate 77. The top of each buckle plate 702 has a second chamfered surface 704 on the side away from the center of the expansion guide plate 77. The pusher 76 rises and abuts against the first chamfered surface 703 of each expansion block 70 and pushes each expansion block 70 to separate from each other. The top of the expansion guide plate 77 is equipped with three or more expansion cover plates 705. Each expansion cover plate 705 is located above a corresponding expansion guide groove 79. The expansion cover plate 705 limits the expansion block 70 longitudinally.

[0069] By adopting the above technical solution, the first O-ring is fitted onto the common outer surface of each buckle plate 702. The pusher drive device 74 drives the pusher 76 to rise. The rising pusher 76 abuts against the first chamfered surface 703 of each expansion block 70 and pushes the expansion blocks 70 to disperse. The buckle plates 702 disperse to collectively expand the first O-ring, preparing for the first O-ring assembly mechanism 9 to pass through the expanded first O-ring. When the pusher drive device 74 drives the pusher 76 to fall, each second elastic element 701 pushes a corresponding expansion block 70 to move towards the intersection of each expansion guide groove 79 to achieve mutual contact between the expansion blocks 70. The mutual contact of the expansion blocks 70 releases the expansion of the first O-ring, allowing the first O-ring to be fitted into the first O-ring assembly mechanism 9. In this embodiment, the pusher drive device 74 is preferably a cylinder. The second elastic element 701 is preferably a spring.

[0070] Referring to FIG14, the first O-ring assembly mechanism 9 includes an O-ring assembly mounting bracket 91 mounted on the top of the chassis 1. At least two second linear guide rails 92 are mounted laterally on one side of the O-ring assembly mounting bracket 91. A fourth slider 93 is slidably mounted on each second linear guide rail 92. An O-ring conveyor slide plate 94 is mounted on each fourth slider 93. A second connecting block 95 is mounted at the top of the O-ring conveyor slide plate 94. An O-ring transverse movement drive device 96 is mounted at the top of the O-ring assembly mounting bracket 91. The output end of the O-ring transverse movement drive device 96 is fixedly connected to the second connecting block 95. The O-ring transverse movement drive device 96 drives the second connecting block 95. The receiving block 95 moves laterally along the second linear guide rail 92. An O-ring clamping lifting drive device 97 and an O-ring set lifting drive device 98 are installed side by side on the O-ring conveying slide plate 94. A sixth mounting plate 99 is installed on the output end of the O-ring clamping lifting drive device 97. The O-ring clamping lifting drive device 97 drives the sixth mounting plate 99 to move up and down. An O-ring clamping assembly 90 is installed on the sixth mounting plate 99. A seventh mounting plate 901 is installed on the output end of the O-ring set lifting drive device 98. The O-ring set lifting drive device 98 drives the seventh mounting plate 901 to move up and down. An O-ring set assembly 902 is installed on the seventh mounting plate 901.

[0071] By adopting the above technical solution, the O-ring lateral movement drive device 96 drives the second connecting block 95 to move, thereby driving the O-ring conveyor slide 94 to move along the second linear guide rail 92. The O-ring conveyor slide 94 drives the O-ring clamping lifting drive device 97 and the O-ring assembly lifting drive device 98 to move laterally. The O-ring conveyor slide 94 drives the O-ring clamping assembly 90 to move up and down, ultimately realizing the movement of the O-ring clamping assembly 90 in a vertical two-dimensional space. The O-ring assembly lifting drive device 98 drives the O-ring assembly 902 to move up and down, ultimately realizing the movement of the O-ring assembly lifting drive device 98 in a vertical two-dimensional space. In this embodiment, the O-ring lateral movement drive device 96 is preferably configured as a cylinder. The O-ring clamping lifting drive device 97 and the O-ring assembly lifting drive device 98 are preferably configured as slide table cylinders.

[0072] Referring to Figures 14 and 15, the O-ring clamping assembly 90 includes a first finger clamping drive device 903 mounted on a sixth mounting plate 99. Movable fingers 904 are respectively mounted on the two output ends of the first finger clamping drive device 903. The two movable fingers 904 are located below the first finger clamping drive device 903 and are symmetrically arranged. Finger clamping mounting seats 905 are respectively mounted on both sides of the first finger clamping drive device 903. Fixed fingers 906 are respectively mounted on the bottom ends of the two finger clamping mounting seats 905. The two fixed fingers 906 are symmetrically arranged.

[0073] By adopting the above technical solution, the first finger-clamping drive device 903 drives the two movable fingers 904 to move closer together, and the fixed finger 906 separates from the adjacent movable finger 904 to avoid the ring body of the first O-ring 68. The O-ring clamping lifting drive device 97 drives the sixth mounting plate 99 to move downward, thereby driving the first finger-clamping drive device 903 to move downward. The first finger-clamping drive device 903 drives the two movable fingers 904, the two finger-clamping mounting seats 905, and the two fixed fingers 906 to move downward. The O-ring clamping assembly 90 docks with the O-ring positioning fixture 64, and the ring body of the first O-ring 68 enters between the fixed finger 906 and the adjacent movable finger 904. The fixed finger 906 and the adjacent movable finger 904... 04 Insert the O-ring into the corresponding finger-avoiding hole 67 of the lower O-ring positioning fixture 64. The first finger-driving device 903 drives the two movable fingers 904 to move away from each other. The outer periphery of the first O-ring 68 is supported by two symmetrically arranged fixed fingers 906. The first finger-driving device 903 drives the two movable fingers 904 to separate from each other to push the ring body of the first O-ring 68 onto their respective fixed fingers 906. The fixed fingers 906 and the adjacent movable fingers 904 jointly clamp the ring body of the first O-ring 68, which replaces the traditional method of the finger-driving device driving the two movable fingers 904 to move closer to each other to clamp the O-ring. This avoids the problem of the O-ring being deformed due to the two movable fingers 904 clamping the O-ring.

[0074] When the O-ring clamping assembly 90 aligns with the first O-ring expansion mechanism 7, the O-ring clamping lifting drive 97 drives the sixth mounting plate 99 downward, which in turn drives the first clamping finger drive 903 downward. The first clamping finger drive 903 drives the two movable clamping fingers 904, the two clamping finger mounting seats 905, the two fixed clamping fingers 906, and the first O-ring 68 downward. The two fixed clamping fingers 906 and the first O-ring 68 move above the first O-ring expansion mechanism 7. The first clamping finger drive 903 drives the two movable clamping fingers 904 to move closer together. The two sets of fixed clamping fingers 906 and movable clamping fingers 904 simultaneously release the first O-ring 68, so that the first O-ring 68 is fitted onto the common outer periphery of each buckle plate 702 and falls onto each expansion block 70, thus realizing the automated feeding and conveying of the first O-ring 68.

[0075] In this embodiment, the first gripper drive device 903 is preferably configured as a pneumatic gripper.

[0076] Referring to FIG16, the O-ring assembly 902 includes a sleeve mounting base 9021 mounted on a seventh mounting plate 901, a sleeve 9022 mounted on the sleeve mounting base 9021 along the longitudinal direction, an eighth mounting plate 9023 mounted on the upper end of the sleeve 9022, a stripping ring drive device 9024 mounted on the eighth mounting plate 9023, a stripping ring 9025 sleeved on the lower end of the sleeve 9022, the output end of the stripping ring drive device 9024 being fixedly connected to the stripping ring 9025, the stripping ring drive device 9024 driving the stripping ring 9025 to slide up and down on the sleeve 9022, and a buckle plate clearance groove 9026 provided at the lower end of the sleeve 9022 for clearance of the buckle plate 702, the number of buckle plate clearance grooves 9026 being equal to the number of expansion blocks 70.

[0077] Referring to Figures 14 and 16, by adopting the above-described technical solution, when the O-ring assembly 902 moves to dock with the first O-ring expansion mechanism 7, the O-ring assembly lifting drive device 98 drives the seventh mounting plate 901 to move downward, thereby driving the O-ring assembly 902 to move downward. At the same time, the stripping ring drive device 9024 drives the stripping ring 9025 to rise to expose the buckle plate clearance groove 9026 of the sleeve 9022. The O-ring assembly 902 moves downward so that each buckle plate clearance groove 9026 on the sleeve 9022 is respectively fitted onto the corresponding buckle plate 702 below it, realizing the docking of the sleeve 9022 with each buckle plate 702. The first O-ring expansion mechanism 7 releases the expansion of the first O-ring, and the first O-ring shrinks and recovers its deformation and is fitted onto the lower end of the sleeve 9022 to realize the automatic removal of the expanded first O-ring from the sleeve 9022.

[0078] When the O-ring assembly 902 moves to dock with the piston feeding mechanism 8, the O-ring assembly lifting drive 98 drives the seventh mounting plate 901 to move downward, thereby driving the O-ring assembly 902 to move downward. The sleeve 9022 is fitted onto the piston on the piston positioning fixture 86 of the piston feeding mechanism 8. The stripping ring drive 9024 drives the stripping ring 9025 to descend, so as to push the first O-ring on the lower end of the sleeve 9022 out of the sleeve 9022. After the first O-ring is separated from the sleeve 9022, it is fitted onto the piston, realizing the automated assembly of the first O-ring on the piston.

[0079] The process of assembling the first O-ring for the piston in the automatic steam pump assembly machine is as follows: The O-ring lateral movement drive device 96 and the O-ring clamping and lifting drive device 97 of the first O-ring assembly mechanism 9 jointly drive the O-ring clamping assembly 90 to move in the longitudinal two-dimensional space. The O-ring lateral movement drive device 96 and the O-ring assembly lifting drive device 98 jointly drive the O-ring assembly 902 to move in the longitudinal two-dimensional space. The O-ring clamping assembly 90 clamps the first O-ring from the O-ring positioning fixture 64 of the first O-ring feeding mechanism 6. The O-ring lateral movement drive device 96 and the O-ring clamping and lifting drive device 97 jointly drive the O-ring clamping assembly 902 to move in the longitudinal two-dimensional space. The first O-ring on component 90 is moved above the first O-ring expansion mechanism 7 and released. The first O-ring is then fitted onto the common outer periphery of each expansion block 70 and placed on top of each expansion block 70. Each expansion block 70 of the first O-ring expansion mechanism 7 passes through and expands the first O-ring, thus completing the feeding, conveying, and positioning of a single first O-ring assembly, preparing for the O-ring assembly 902 to pass through the first O-ring. Then, the O-ring lateral movement drive 96 and the O-ring clamping lifting drive 97 jointly drive the O-ring clamping assembly 90 to move to the top of the first O-ring feeding mechanism 6 to clamp the next first O-ring. The O-ring lateral movement drive 96 and the O-ring assembly lifting drive 98 work together to move the O-ring assembly 902 above each expansion block 70. Simultaneously, the O-ring assembly 902 exposes the buckle plate clearance groove 9026 at the lower end of the sleeve 9022. The O-ring assembly lifting drive 98 lowers the sleeve 9022 to align with each buckle plate 702. The first O-ring expansion mechanism 7 releases its support for the first O-ring, and the first O-ring retracts and automatically fits onto the lower end of the sleeve 9022, completing the process of inserting and expanding the first O-ring from the sleeve 9022. The O-ring lateral movement drive 96, the O-ring clamping lifting drive 97, and the O-ring clamping assembly 90 work together to lift the first O-ring from the... The material feeding mechanism 6 picks up the next first O-ring and puts it onto the first O-ring expansion mechanism 7. The first O-ring expansion mechanism 7 expands the next first O-ring to position it. This completes the feeding, conveying and positioning of the next first O-ring. The O-ring lateral movement drive device 96 and the O-ring assembly lifting drive device 98 jointly drive the O-ring assembly 902 and the first O-ring on it to move above the piston feeding mechanism 8 and dock with the piston feeding mechanism 8. The O-ring assembly 902 puts the first O-ring on the sleeve 9022 onto the piston circumference of the piston on the piston positioning fixture 86 of the piston feeding mechanism 8 in the aforementioned manner. This completes the automatic assembly of the first O-ring for a single piston.

[0080] In this embodiment, the stripping ring drive device 9024 is preferably configured as a cylinder.

[0081] Referring to Figure 17, the piston assembly mechanism 10 includes a piston assembly upright plate 101 mounted on the top of the housing 1.

A ninth mounting plate 103 is mounted on the output end of the suction rod lateral movement drive device 102. The suction rod lateral movement drive device 102 drives the ninth mounting plate 103 to move laterally. Two or more third linear guide rails 104 are mounted on the ninth mounting plate 103 along the longitudinal direction. Each third linear guide rail 104 is parallel to each other, and a fifth slider 105 is slidably mounted on each third linear guide rail 104. A tenth mounting plate 106 is mounted on each fifth slider 105. The top of the tenth mounting plate 106... The tenth mounting plate 106 is mounted on a tenth mounting plate 106, which is equipped with a third connecting block 107 and a suction rod lifting drive device 108 at the top of the ninth mounting plate 103. The output end of the suction rod lifting drive device 108 is fixedly connected to the third connecting block 107. The suction rod lifting drive device 108 drives the third connecting block 107 to move up and down, thereby driving the tenth mounting plate 106 to move up and down. The tenth mounting plate 106 is equipped with a piston penetration drive device 109 and a suction rod guide seat 100 from top to bottom. A piston suction rod 1001 is mounted on the suction rod guide seat 100 along the longitudinal direction. The piston suction rod 1001 moves through the suction rod guide seat 100. The output end of the piston penetration drive device 109 is fixedly connected to the piston suction rod 1001.

The suction rod lateral movement drive device 102 and the suction rod lifting drive device 108 together drive the tenth mounting plate 106 to move in the longitudinal two-dimensional space, thereby driving the suction rod guide seat 100, the piston insertion drive device 109 and the piston suction rod 1001 to move in the longitudinal two-dimensional space. The suction rod lateral movement drive device 102 and the suction rod lifting drive device 108 together drive the piston suction rod 1001 to move above the piston positioning fixture 86. The piston insertion drive device 109 drives the piston suction rod 1001 to insert into the piston. The suction rod 1001 is connected to an external vacuum system. By evacuating the suction hole 1106 at the bottom of the piston suction rod 1001, the piston suction rod 1001 can be inserted into the piston and the piston can be tightly sucked. The suction rod lateral movement drive device 102 and the suction rod lifting drive device 108 jointly drive the piston suction rod 1001 and the piston on it to move to the pump housing 2206 on the corresponding pump housing positioning assembly 22 on the circulation conveying mechanism 2. The piston insertion drive device 109 drives the piston suction rod 1001 and the piston on it to insert into the pump housing 2206. The vacuum system inflates the piston suction rod 1001 and releases the vacuum, so that the piston naturally falls into the pump housing 2206. This realizes the automatic completion of piston feeding and conveying and piston assembly in the pump housing 2206, with high assembly efficiency and good assembly effect.

[0083] In this embodiment, the suction rod lateral movement drive device 102 is preferably configured as a rodless cylinder. The suction rod lifting drive device 108 and the piston insertion drive device 109 are both preferably configured as cylinders.

[0084] Referring to Figure 18, the bottom cover assembly mechanism 11 includes a third vibratory plate 111, a third linear vibrator 112, a bottom cover bracket 113, and a bottom cover assembly mounting frame 114 mounted on the top of the housing 1.

One end of the bottom cover material rail 115 is connected to the discharge end of the third vibratory plate 111, and the other end of the bottom cover material rail 115 is connected to the bottom cover positioning fixture. 116 docking; The bottom cover assembly mounting frame 114 is equipped with two or more fourth linear guide rails 117 along the transverse direction. Each fourth linear guide rail 117 is parallel to each other, and a sixth slider 118 is installed on each fourth linear guide rail 117. A bottom cover positioning and moving frame 119 is jointly installed on each sixth slider 118. A fourth connecting block 110 is installed on the top of the bottom cover positioning and moving frame 119. A mold head transverse movement drive device 1101 is installed on the top of the bottom cover assembly mounting frame 114. The output end of the die head transverse movement drive device 1101 is fixedly connected to the fourth connecting block 110. The bottom cover positioning and moving frame 119 is sequentially equipped with a rear cover pressing drive device 1102 and a die head guide plate 1103 from top to bottom. A bottom cover pressing die head 1104 is mounted on the die head guide plate 1103 along the longitudinal direction. The bottom cover pressing die head 1104 movably passes through the die head guide plate 1103. The output end of the rear cover pressing drive device 1102 is fixedly connected to the upper end of the bottom cover pressing die head 1104. The bottom cover pressing die 1104 has a vacuum connection hole 1105 on the outer periphery of its middle part and one or more suction holes 1106 on the outer periphery of its lower end. An eleventh mounting plate 1107 is mounted on one side of the bottom cover assembly mounting bracket 114. A die head limiting plate 1108 is mounted on the eleventh mounting plate 1107. The die head limiting plate 1108 limits the bottom cover pressing die 1104 to move horizontally above the bottom cover positioning fixture 116.

[0085] By adopting the above technical solution, the mold head transverse movement drive device 1101 drives the bottom cover positioning moving frame 119 to move laterally along the fourth linear guide rail 117, thereby driving the rear cover pressing drive device 1102 and the bottom cover pressing mold head 1104 to move laterally. The rear cover pressing drive device 1102 drives the bottom cover pressing mold head 1104 to move up and down, thereby driving the bottom cover 1109 adsorbed on the bottom cover pressing mold head 1104 to move up and down. The mold head transverse movement drive device 1101 drives the bottom cover pressing mold head 1104 to move above the bottom cover positioning fixture 116. The rear cover pressing drive device 1102 drives the bottom cover pressing mold head 1104 to move downward until it contacts the bottom cover 1109 on the bottom cover positioning fixture 116. The vacuum connection port 1105 is used to connect an external vacuum system to evacuate the suction holes 1106 on the bottom cover pressing mold head 1104 to pick up the bottom cover 1109. The transfer drive device 1101 drives the bottom cover pressing die head 1104 to move above the pump housing 2206 on the corresponding pump housing positioning assembly 22 on the circulation conveying mechanism 2. The rear cover pressing drive device 1102 drives the bottom cover pressing die head 1104 and the bottom cover 1109 adsorbed thereon to move downward to the port of the pump housing 2206 and press the bottom cover 1109 into the port of the pump housing 2206. The vacuum system fills the suction holes 1106 on the bottom cover pressing die head 1104 with air to release the vacuum. The bottom cover 1109 is separated from the bottom cover pressing die head 1104, completing the pressing of the bottom cover 1109 onto the pump housing 2206. The bottom cover pressing die head 1104 uses vacuum suction to pick up the bottom cover, replacing the pneumatic gripper to pick up the bottom cover, avoiding the problem of bottom cover deformation caused by the pneumatic gripper pressing the bottom cover. In addition, it has the advantages of accurate positioning and high assembly efficiency in assembling the bottom cover 1109 onto the pump housing 2206.

[0086] In this embodiment, both the die head transverse movement drive device 1101 and the rear cover pressing drive device 1102 are preferably configured as cylinders.

[0087] Referring to FIG19, the pump casing tilting mechanism 12 includes a pump casing lateral movement drive device 121 installed at the bottom of the housing 1. A twelfth mounting plate 122 is installed at the output end of the pump casing lateral movement drive device 121.

A second finger clamping drive device 126 is installed at the output end of the pump casing tilting drive device 125. The pump casing tilting drive device 125 drives the second finger clamping drive device 126 to rotate. Pump casing clamping fingers 127 are respectively installed on the two output ends of the second finger clamping drive device 126. The two pump casing clamping fingers 127 are symmetrically arranged.

[0088] Referring to Figures 4 and 19, by adopting the above-described technical solution, the pump casing lateral movement drive device 121 drives the second gripper finger drive device 126 and the two pump casing gripper fingers 127 to move towards the corresponding pump casing positioning assembly 22 on the circulation conveying mechanism 2. The two pump casing gripper fingers 127 are engaged with the outside of the pump casing placed vertically on the pump casing positioning assembly 22. The second gripper finger drive device 126 drives the two pump casing gripper fingers 127 to move closer together to clamp the pump casing. The pump casing lifting drive device 123 drives the second gripper finger drive device 126, the two pump casing gripper fingers 127, and the pump casing 2206 to move upward, causing the pump casing 2206 to disengage from the pump.

This realizes the flipping and placement of the pump housing 2206, which is used to position the subsequent steam pump assembly. It has the advantages of high flipping efficiency and high positioning accuracy.

[0089] In this embodiment, the pump casing lateral movement drive device 121 is preferably a cylinder. The pump casing lifting drive device 123 is preferably a slide cylinder. The pump casing tilting drive device 125 is preferably a rotary cylinder. The second gripper drive device 126 is preferably a pneumatic gripper.

[0090] Referring to FIG20, the first longitudinal fixing mechanism 16 includes two sensor brackets 161 and a fixed mounting bracket 162 mounted on the top of the chassis 1.

A fixed block 166 is mounted at the bottom of the fixed support plate 165, and a fixing groove 167 adapted to the outer peripheral shape of the pump body is provided at the bottom of the fixed block 166. The structure of the second longitudinal fixing mechanism 18 is the same as that of the first longitudinal fixing mechanism 16.

[0091] Referring to Figures 4 and 20, by adopting the above-described technical solution, when the two photoelectric sensors 163 detect that the pump housing 2206 has been moved into position, the fixing block lifting drive device 164 drives the fixing support plate 165 to move downward, thereby causing the fixing block 166 to move downward. The fixing block 166 moves downward and presses the pump housing 2206 against the first positioning groove 227 of the first positioning block 225 and the second positioning groove 228 of the second positioning block 226. The fixing groove 167 of the fixing block 166 cooperates with the first positioning groove 227 of the first positioning block 225 and the second positioning groove 228 of the second positioning block 226 to position and fix the pump housing 2206, avoiding displacement during subsequent steam pump assembly and thus preventing assembly failure.

[0100] Referring to Figures 22 and 23, by adopting the above-described technical solution, the nozzle lateral movement drive device 1736 drives the sixth connecting block 1735 to move laterally, thereby causing the fifteenth mounting plate 1734 to move laterally along the sixth linear guide rail 1732.

[0101] Referring to FIG24, the finished product guiding mechanism 19 includes a first guiding assembly 191, a second guiding assembly 192, and a guide plate 193 mounted on the top of the housing 1. The first guiding assembly 191 includes two or more support rod seats 194. The top of each support rod seat 194 is equipped with a support rod 195 in the transverse direction. The same end of each support rod 195 is equipped with a guide rod 196 for guiding the pump housing. The end of the guide rod 196 opposite to the circulating conveying mechanism 2 is provided with a tip 197. The other end of the rod 196 is bent downwards and has a bend 198. The bend 198 of the guide rod 196 is used to guide the finished product pump discharge collection. The structure of the second guide assembly 192 is mirror-symmetrical to the structure of the first guide assembly 191. The guide plate 193 is located below the bend 198 of the guide rod 196 of the first guide assembly 191 and the bend 198 of the guide rod 196 of the second guide assembly 192. The guide plate 193 is obliquely arranged and is used to guide the finished product pump discharge collection.

[0102] By adopting the above technical solution, the circulating conveying mechanism 2 conveys the pump casing along the assembly line. After the pump casing is assembled, the finished pump reaches the discharge end of the circulating conveying mechanism 2. The tips 197 of the guide rods 196 of the first guide assembly 191 and the second guide assembly 192 are respectively aligned with the guide holes on both sides of the pump casing. The finished pump is conveyed by the circulating conveying mechanism 2 along the tips 197 and guide rods 196 of the first guide assembly 191 and the second guide assembly 192. The guide rods 197 and 197 of the first guide assembly 191 are also conveyed along the guide rods 196 of the second guide assembly 192. The guide rod 196 of the second guide assembly 192 supports and guides the finished product pump. After the finished product pump is separated from the pump casing positioning assembly 22 of the circulation conveying mechanism 2, it falls onto the guide plate 193 along the bend 198 of the guide rod 196 of the first guide assembly 191 and the bend 198 of the guide rod 196 of the second guide assembly 192, and is fed along the guide plate 193. This replaces the traditional method of using a robotic arm to grip the finished product pump for feeding and collection. The finished product guiding mechanism 19 has a simple structure, low cost, and is easy and convenient to maintain.

[0103] The automatic steam pump assembly machine's overall structural design enables the separate feeding and conveying of components such as the pump casing, spring, piston, first O-ring, and second O-ring on a single machine. It positions the pump casing positioning assembly 22 and automatically completes multiple assembly processes, including internal oil spraying, spring installation, first O-ring hole enlargement, piston and first O-ring assembly, second O-ring hole enlargement, pump casing and piston assembly, pump casing and bottom cover assembly, 90-degree pump casing rotation, nozzle and second O-ring assembly, pump casing and nozzle press-fitting, and finally, unloading and collecting the finished pump. This achieves fully automated assembly of the steam pump, avoiding issues such as O-ring distortion, bottom cover deformation, damage to workpiece surfaces, nozzle misalignment, and inadequate sealing. The fast flow between workstations, strong assembly and correction capabilities, and precise positioning greatly shorten the assembly cycle of a single steam pump, resulting in high overall assembly efficiency, high assembly precision, good assembly effect, and high finished product yield. It also significantly reduces the assembly intensity and cost for workers. It effectively solves the problems of current semi-automatic steam pump assembly machines, which cannot automate multiple different assembly processes on the same machine, leading to dispersed processes, time-consuming flow, and long assembly cycles for a single steam pump. It also solves the problems of current semi-automatic steam pump assembly machines using movable grippers to hold O-rings, pneumatic grippers to hold bottom covers, and robotic arms to hold finished pumps, which result in O-rings being easily deformed, bottom covers being easily deformed, workpiece surfaces being easily damaged, and high material costs for finished pumps.
