Description

Technical Field

[0001] This invention belongs to the field of plunger pump assembly technology, and particularly relates to an assembly system and method for plunger pumps. Background Technology

[0002] Currently, piston pumps, as the core power component of hydraulic transmission systems, are widely used in key fields such as engineering machinery, aerospace, and petrochemicals. Their assembly quality and efficiency directly affect the production safety, operating efficiency, and operating costs of downstream industries, and are crucial to ensuring the stable development of related industries.

[0003] Currently, in plunger pump assembly, multiple parts within the pump need to be assembled using separate equipment. Due to the dispersed nature of these devices, the plunger pump requires multiple transfers during assembly, from the positioning equipment to the spring feeding equipment, and then sequentially to equipment for gasket installation and plunger cap assembly. This process necessitates manual assistance or the use of simple conveyor devices for connection. However, the positioning standards of each piece of equipment are difficult to standardize, and multiple transfers can easily lead to part misalignment, resulting in problems such as spring tilting and gasket misalignment. This affects assembly accuracy, product quality consistency, and stability. Furthermore, multiple transfers increase process intervals, leading to low assembly efficiency.

[0004] To solve the above-mentioned technical problems, the present invention designs an assembly system and method for a plunger pump. Summary of the Invention

[0018] Secondly, the present invention provides an assembly method for a plunger pump, applied to an assembly system for a plunger pump as described in any of the above embodiments, comprising the following steps: S1, a plunger seat feeding mechanism feeds a plunger seat to a clamping and positioning mechanism, the clamping and positioning mechanism clamps the plunger seat; S2, the clamping and positioning mechanism moves along a guide rail to a position corresponding to a pre-positioning mechanism, the pre-positioning mechanism positions and adjusts the placement position and angle of the plunger seat, and the clamping and positioning mechanism continues to move along the guide rail; S3, the clamping and positioning mechanism moves along the guide rail to a position corresponding to a plunger spring feeding mechanism, the plunger spring feeding mechanism installs a spring into a preset position inside the plunger seat, and the clamping and positioning mechanism continues to move along the guide rail; S4, the clamping and positioning mechanism moves along... The guide rail moves to the corresponding position of the plunger gasket installation mechanism, which accurately installs the gasket into the preset position of the plunger seat. The clamping and positioning mechanism continues to move along the guide rail. S5, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger cover assembly mechanism, which assembles the plunger cover into the preset position of the plunger seat, sleeved over the spring and gasket, completing the assembly of the plunger pump. S6, the clamping and positioning mechanism moves along the guide rail to the plunger pump gasket detection mechanism, which determines whether a gasket is missing from the assembled plunger pump. If a gasket is missing, the plunger pump is transferred to the scrap bin. If no gasket is missing, the plunger pump is returned to the storage tray.

[0019] Based on the above technical solution, step S3 includes the following steps: S3.1, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger spring feeding mechanism, and the plunger spring enters the material distribution component through the first conveying pipe from the first vibrating plate, and the material distribution component distributes the plunger spring; S3.2, the push plate moves along the direction close to the first feed port, and pushes the distributed plunger spring into the plunger spring placement slot corresponding to the first rotating seat; S3.3, the first rotating seat rotates relative to the first fixed seat until the next plunger spring placement slot corresponds to the first feed port, and the push plate pushes the next plunger spring into the plunger spring placement slot, and so on, until all the plunger spring placement slots in the first rotating seat are filled; S3.4, the gripping mechanism moves the multiple plunger springs simultaneously into the plunger seat to be assembled, and the clamping and positioning mechanism continues to move along the guide rail.

[0020] Based on the above technical solution, the step S3.1 of distributing the plunger springs includes the following steps: S3.11, multiple plunger springs enter the first distribution channel through the first conveying pipe from the first vibrating plate; S3.12, the first cylinder extends to block all the plunger springs falling in the first distribution channel; S3.13, when the plunger springs fall to contact the extended first cylinder, the second cylinder extends, the free height of the plunger springs is Hf, and the range of the height H between the first cylinder and the second cylinder is Hf < H < 2Hf. When the second cylinder extends, it presses down the second plunger spring counted from bottom to top; S3.14, the first cylinder retracts, and the first plunger spring counted from bottom to top, which is the lowest, falls to the bottom of the first distribution seat; S3.15, the push plate moves along the direction close to the discharge port, pushes the plunger springs out of the discharge port, pushes them into the corresponding plunger spring placement slots through the first inlet, the push plate retracts, and returns to step S3.12 to continue distributing.

[0021] Compared with related technologies, the beneficial effects of the present invention are as follows: This invention, through the establishment of a ring guide rail mechanism, enables efficient transfer of plunger seats between different workstations. A plunger seat loading mechanism is responsible for loading the plunger seats onto a clamping and positioning mechanism. The clamping and positioning mechanism moves along the guide rail to the corresponding position of the pre-positioning mechanism, ensuring accurate positioning of the plunger seat through precise positioning and adjustment. The clamping and positioning mechanism then moves along the guide rail to the plunger spring loading station, where it installs the spring into a designated position within the plunger seat. Next, the clamping and positioning mechanism continues to move along the guide rail to the plunger gasket installation station, where it accurately installs the gasket into the designated position within the plunger seat. After gasket installation, the clamping and positioning mechanism transfers the plunger seat to the plunger cap assembly station, where it assembles the plunger cap onto the spring and gasket, completing the assembly of the entire plunger pump. The entire assembly process is completed collaboratively by multiple mechanisms; through precise control and coordination, the efficient and accurate assembly of the plunger pump is achieved.

[0028] Combination Figure 1 As shown in the figure, this embodiment of the present disclosure provides an assembly system for a plunger pump, including a machine base 8 and an annular guide rail mechanism 7. The annular guide rail mechanism 7 is located at the center of the machine base 8. The annular guide rail mechanism 7 is provided with a plunger seat feeding mechanism 1, a plunger spring feeding mechanism 2, a plunger gasket mounting mechanism 3, and a plunger cover assembly mechanism 4 in sequence along its circumference. The annular guide rail mechanism 7 is provided with a guide rail 71 and a clamping and positioning mechanism 15. The clamping and positioning mechanism 15 is used to clamp the plunger seat 16 to be assembled. A pre-positioning mechanism 6 is provided between the plunger seat feeding mechanism 1 and the plunger spring feeding mechanism 3. The pre-positioning mechanism 6 is used to position the plunger seat 16. The clamping and positioning mechanism 15 can move along the guide rail circumferentially to the corresponding positions of the plunger seat feeding mechanism 1, the pre-positioning mechanism 6, the plunger spring feeding mechanism 2, the plunger gasket mounting mechanism 3, and the plunger cover assembly mechanism 4.

[0029] The plunger pump assembly system provided in this embodiment enables efficient transfer of the plunger seat 16 between different stations by setting up the annular guide rail mechanism 7. The plunger seat feeding mechanism 1 is responsible for feeding the plunger seat 16 onto the clamping and positioning mechanism 15. The clamping and positioning mechanism 15 moves along the guide rail 71 to the corresponding position of the pre-positioning mechanism 6. Through the precise positioning and adjustment of the plunger seat 16 by the pre-positioning mechanism 6, the accurate position of the plunger seat 16 is ensured. The clamping and positioning mechanism 15 moves along the guide rail 71 to the plunger spring feeding station, where the plunger spring feeding mechanism 2 installs the spring into the designated position inside the plunger seat 16. Next, the clamping and positioning mechanism 15 continues to move along the guide rail 71 to the plunger gasket installation station, where the plunger gasket installation mechanism 3 accurately installs the gasket into the designated position of the plunger seat 16. After the gasket is installed, the clamping and positioning mechanism 15 moves the plunger seat 16 to the plunger cover assembly station. The plunger cover assembly mechanism 4 then assembles the plunger cover body 544 onto the spring 452 and the gasket 543, thus completing the assembly of the entire plunger pump. The entire assembly process is completed collaboratively by multiple mechanisms. Through precise control and coordination, the efficient and accurate assembly of the plunger pump is achieved.

[0030] Based on the above technical solutions, such as Figure 2 As shown, the annular guide rail mechanism 7 includes a support assembly and a drive assembly. The guide rail 71 is disposed on the support assembly. The support assembly includes multiple support seats 72 and a support plate 73. The multiple support seats 72 are supported below the support plate 73. The guide rail 71 is disposed on the support plate 73. The drive assembly includes a first rotating disk 74, a second rotating disk 75, and a rotating belt 76 disposed above the support plate, and a drive motor disposed below the support plate 73. The rotating belt 76 is sleeved on the first rotating disk 74 and the second rotating disk 75. The drive motor is connected to the first rotating disk 74 and the second rotating disk 75, and can drive the first rotating disk 74 and the second rotating disk 75 to rotate. The guide rail 71 is arranged around the rotating belt 76. The clamping and positioning mechanism 15 is provided with a rotating mating seat 77. One side of the rotating mating seat 77 is connected to the rotating belt 76. The bottom of the rotating mating seat 77 is provided with a pulley. The pulley can slide relative to the guide rail 71, so that the clamping and positioning mechanism 15 can perform a circular motion relative to the guide rail 71.

[0031] Combination Figure 3-5As shown, the plunger seat feeding mechanism 1 includes a storage tray 11, a first transfer mechanism 12, a placement mechanism 13, and a detection mechanism 14. The placement mechanism 13 is located below the detection mechanism 14. The placement mechanism 13 includes a rotary drive assembly 131, the top of which is a plunger seat placement position 132. The rotary drive assembly 131 can drive the plunger seat 16 to rotate. The storage tray 11 is located on one side of the placement mechanism 13, and the clamping and positioning mechanism 15 is located on the placement mechanism 13. On the other side, the first transfer mechanism 12 is used to move the plunger seat 16 from the storage tray 11 to the placement mechanism 13 and from the placement mechanism 13 to the clamping and positioning mechanism 15. The clamping and positioning mechanism 15 includes a clamping component 151 and a plurality of positioning pins 152. The clamping component 151 is used to clamp and fix the plunger seat 16. The plurality of positioning pins 152 are disposed on the clamping component 151. The plunger seat 16 includes a plurality of mounting holes 161. The plurality of positioning pins 152 are correspondingly disposed with the plurality of mounting holes 161.

[0032] Using the plunger seat feeding mechanism 1 described in this embodiment, a storage tray 11 is set up to store the plunger seats 16 to be fed. The first transfer mechanism 12 picks up the plunger seats 16 in the storage tray 11 and moves them to the plunger seat placement position 132 of the placement mechanism 13. The placement angle of the plunger seat 16 is detected by the detection mechanism 14 above. If there is a deviation between the placement angle and the standard angle, the rotation drive assembly 131 drives the plunger seat 16 to rotate to reach the standard angle. Then, the first transfer mechanism 12 moves the storage tray 11 to the clamping and positioning mechanism 15, and places the multiple mounting holes 161 of the plunger seat 16 and the multiple positioning pins 152 correspondingly. The clamping assembly 151 clamps and fixes the plunger seat 16 for subsequent assembly.

[0033] Batch feeding via storage tray 11 reduces the frequency of manual intervention. The flexibility of the first transfer mechanism 12 ensures the rapid transfer of plunger seat 16 between different workstations. The detection mechanism 14 effectively avoids assembly problems caused by angular deviations, further improving product quality. The clamping and positioning mechanism 15 achieves accurate positioning of plunger seat 16 through the precise cooperation of multiple positioning pins 152 and mounting holes 161, facilitating subsequent processing or assembly. The plunger seat 16 feeding mechanism 1 ensures the stability and accuracy of plunger seat 16 during the feeding process through the coordinated work of multiple functional modules.

[0034] Based on the above technical solutions, such as Figure 3As shown, the first transfer mechanism 12 includes a first X-axis drive mechanism 121, a first Y-axis drive mechanism 122, a first Z-axis drive mechanism 123, and a first moving head 124. The first Y-axis drive mechanism 122 is disposed on the first X-axis drive mechanism 121, the first Z-axis drive mechanism 123 is disposed on the first Y-axis drive mechanism 122, and the first moving head 124 is disposed at the end of the first Z-axis drive mechanism 123.

[0035] Specifically, the first X-axis drive mechanism 121, the first Y-axis drive mechanism 122, and the first Z-axis drive mechanism 123 can drive the first moving head 124 to move along the X, Y, and Z directions, thereby achieving precise transfer of the plunger seat 16 between the storage tray 11, the placement mechanism 13, and the clamping and positioning mechanism 15. The first X-axis drive mechanism 121, the first Y-axis drive mechanism 122, and the first Z-axis drive mechanism 123 all employ high-precision servo motors in conjunction with slide rails to ensure stability and positioning accuracy during the transfer process.

[0036] Optionally, there are multiple first Z-axis drive mechanisms 123, and multiple first Z-axis drive mechanisms 123 are sequentially arranged on the first Y-axis drive mechanism 122 along the Y-axis direction. Multiple first Z-axis drive mechanisms 123 are correspondingly provided with multiple first moving heads 124, and multiple first moving heads 124 can move multiple plunger seats 16 simultaneously.

[0037] Furthermore, such as Figure 4 As shown, the first moving head 124 includes a first arm 1241 and a second arm 1242 arranged opposite to each other. The end of the first Z-axis drive mechanism 123 is provided with a slide rail 1231. The first arm 1241 and the second arm 1242 can move closer or further apart along the slide rail 1231.

[0038] Specifically, the plunger seat 16 has a central hole. When the first arm 1241 and the second arm 1242 are in close contact, the total diameter of the ends of the first arm 1241 and the second arm 1242 is less than or equal to the diameter of the central hole. When the first arm 1241 and the second arm 1242 are close together, they are inserted into the central hole. When the first arm 1241 and the second arm 1242 are relatively far apart, they are supported within the central hole to drive the plunger seat 16 to move. The moving head uses the cooperation of the first arm 1241 and the second arm 1242 to perform an internal support extraction of the plunger seat 16, avoiding damage to the surface of the plunger seat 16 that may be caused by traditional clamping methods. It also avoids interference with surrounding components when transferring to another workstation, ensuring the firmness and stability of the plunger seat 16 during the transfer process, while improving the efficiency and accuracy of the transfer. In addition, the slide rail 1231 makes the movement of the first arm 1241 and the second arm 1242 smoother, reducing errors caused by mechanical vibration.

[0039] Based on the above technical solutions, such as Figure 5 As shown, the placement mechanism 13 further includes a first base 133, and the rotary drive assembly 131 includes a first drive motor 134 and a rotary seat 135. The first drive motor 134 is disposed on the first base 133, and the rotary seat 135 is connected to the first drive motor 134. The top of the rotary seat 135 is the plunger seat placement position 132.

[0040] Specifically, such as Figure 5 As shown, the first base 133 is provided with multiple support legs 136, and the tops of the multiple support legs 136 jointly support a limiting plate 137. The limiting plate 137 is provided with a through hole 1515. The rotating seat 135 is provided on the limiting plate 137. The rotating seat 135 is provided with a rotating shaft. The rotating shaft passes through the through hole 1515 and extends toward the first drive motor 134. The rotating shaft and the first drive motor 134 are connected by a first coupling 138. The top of the rotating seat 135 is provided with a positioning pin.

[0041] The first drive motor 134 drives the rotating shaft to rotate via the first coupling 138, thereby driving the rotating seat 135 and the plunger seat 16 at its top to rotate. The design of the limiting plate 137 not only supports the rotating seat 135, but also guides and limits the movement of the rotating shaft through the through hole 1515, ensuring the smoothness and accuracy of the rotation process. In addition, a positioning pin is provided at the top of the rotating seat 135. When the plunger seat 16 is placed in the plunger seat placement position 132, the positioning pin is inserted into the middle hole of the plunger seat 16 to further fix the plunger seat 16 and prevent the plunger seat 16 from shifting or shaking during rotation.

[0042] Optionally, there are multiple rotary drive components 131, which are distributed in a regular manner on the first base 133, and can drive multiple plunger seats 16 to rotate at the same time, thereby improving the feeding efficiency.

[0043] Based on the above technical solution, the detection mechanism 14 includes an image acquisition device, which is located on the first Y-axis drive mechanism.

[0044] Specifically, the image acquisition device is a camera. The first Y-axis drive mechanism has a fixed plate that extends downwards. The camera is located on one side of the fixed plate, and the first Z-axis drive mechanism is located on the other side of the fixed plate. Preferably, the camera is located on the side of the fixed plate closest to the storage tray 11. By setting the camera to acquire images of the plunger seat 16 placed on the placement mechanism 13, it is determined whether the placement angle of the plunger seat 16 reaches the standard angle. If the placement angle of the plunger seat 16 does not reach the standard angle, it is adjusted by rotating the component, and the camera acquires images again until the placement angle reaches the standard angle, and then the next step of transfer is performed.

[0045] Optionally, there are multiple image acquisition devices, and the multiple image acquisition devices are correspondingly arranged with multiple plunger seats 16 on the placement mechanism 13, so as to perform image acquisition on the multiple plunger seats 16 respectively.

[0046] Based on the above technical solutions, such as Figure 6 As shown, the clamping assembly 151 includes a base plate 1511, a driving part 1512, a first fixing part 1513, and a movable part 1514. The first fixing part 1513 and the movable part 1514 are disposed on the base plate 1511. The positioning pin 152 is disposed on the base plate 1511 between the first fixing part 1513 and the movable part 1514. The driving part 1512 is disposed on the side of the first fixing part 1513 away from the movable part 1514. The driving part 1512 can drive the movable part 1514 to move in a direction close to or away from the first fixing part 1513 to clamp or release the plunger seat 16.

[0047] Furthermore, such as Figure 6 As shown, the first fixed part 1513 is provided with a through hole 1515, the movable part 1514 is provided with a movable shaft 1516, the movable shaft 1516 passes through the through hole 1515 and protrudes from the first fixed part 1513, the driving part 1512 includes a piston 1517, the end of the piston 1517 is correspondingly provided with the end of the movable shaft 1516, and a first elastic member 1518 is provided between the base plate 1511 and the movable part 1514 along the movement direction of the movable part 1514.

[0048] When the first transfer mechanism 12 moves the plunger seat 16 from the placement mechanism 13 to the clamping assembly 151, the piston 1517 moves toward the movable shaft 1516, driving the movable shaft 1516 to move the movable part 1514 away from the first fixed part 1513, thereby increasing the distance between the first fixed part 1513 and the movable part 1514, so that the first transfer mechanism 12 can place the plunger seat 16 between the first fixed part 1513 and the movable part 1514. At this time, the first elastic member 1518 is in a compressed state. Then, the piston 1517 moves away from the movable shaft 1516, and the first elastic member 1518, under the action of the restoring force, pushes the movable part 1514 toward the direction closer to the first fixed part 1513, so as to clamp the plunger seat 16 between the first fixed part 1513 and the movable part 1514 and fix the position of the plunger seat 16.

[0049] Furthermore, such as Figure 7 and Figure 8 As shown, the movable part 1514 has a first recessed hole on its side wall away from the first fixed part 1513, the base plate 1511 has an upwardly extending extension part 1519, the extension part 1519 has a second recessed hole, the first recessed hole and the second recessed hole are arranged correspondingly, one end of the first elastic member 1518 is disposed in the first recessed hole, and the other end of the first elastic member 1518 is disposed in the second recessed hole.

[0050] Specifically, the first and second recesses limit the first elastic member 1518, so that when the movable part 1514 moves relative to the base plate 1511, the first elastic member 1518 extends and retracts along the movement direction of the movable part 1514. The extension 1519 is disposed on the side of the base plate 1511 near the movable part 1514, and when the driving part 1512 drives the movable part 1514 to move, it can maximize the limitation of the movement of the movable part 1514 and prevent the movable part 1514 from moving excessively.

[0051] Furthermore, such as Figure 6 As shown, the first fixing part 1513 has a first groove 1521 on the side wall near the movable part 1514, and the movable part 1514 has a second groove 1522 on the side wall near the first fixing part 1513. The first groove 1521 and the second groove 1522 are correspondingly arranged to jointly enclose the clamping space.

[0052] The first groove 1521 and the second groove 1522 cooperate to further limit the position of the plunger seat 16 and firmly clamp it, preventing displacement during subsequent processing or assembly. The size of the clamping space can be adjusted according to the specific specifications of the plunger seat 16 to accommodate different models of plunger seats 16, enhancing versatility.

[0053] Furthermore, the drive unit 1512 also includes a limit switch for controlling the movement range of the movable unit 1514. When the movable unit 1514 approaches or moves away from the first fixed unit 1513 to a preset position, the limit switch is triggered and stops the operation of the drive unit 1512 to prevent damage to the clamping and positioning mechanism 15 due to excessive movement.

[0054] Preferably, the first groove 1521 is a V-shaped groove and the second groove 1522 is a U-shaped groove. The side wall of the U-shaped groove facing the V-shaped groove is provided with an elastic pressure head. The elastic pressure head and the V-shaped groove cooperate to clamp and fix the plunger seat 16, thereby achieving three-contact point fixation of the plunger seat 16, which can effectively improve the stability and accuracy of clamping.

[0055] Optionally, there are multiple first grooves 1521 and multiple second grooves 1522, which enclose multiple clamping spaces and can clamp and position multiple plunger seats 16.

[0056] Based on the above technical solutions, such as Figure 6 and Figure 8 As shown, the clamping and positioning mechanism 15 also includes a first sensor 153, the end of which is disposed toward the clamping space to detect whether a plunger seat 16 exists in the clamping space.

[0057] Preferably, the first sensor 153 is a photoelectric sensor, which can operate stably in complex environments. The photoelectric sensor accurately determines whether the plunger seat 16 exists in the clamping space by measuring the change in photoelectric signal between the transmitting and receiving ends, while being unaffected by external light interference, ensuring the reliability of the detection results.

[0058] Optionally, there may be multiple first sensors 153, and each of the multiple first sensors 153 may correspond to multiple clamping spaces.

[0059] Based on the above technical solutions, such as Figure 9 As shown, the pre-positioning mechanism 6 includes a fixed frame 61, a vertical drive member 62, a first positioning pin 63 and a second positioning pin 64. The vertical drive member 62 is disposed on the fixed frame 61, and the first positioning pin 63 and the second positioning pin 64 are disposed at the ends of the vertical drive member 62. The first positioning pin 63 and the second positioning pin 64 correspond to the mounting holes 161 of the plunger seat 16, respectively.

[0060] Specifically, the first positioning pin 63 is cylindrical and the second positioning pin 64 is rhomboid. The positioning is achieved by using a combination of cylindrical and rhomboid shapes to avoid excessive precision when both the first positioning pin 63 and the second positioning pin 64 are cylindrical, which could cause interference with the edge of the mounting hole of the plunger seat 16 and damage to the plunger seat 16, thus avoiding positioning problems.

[0061] Combination Figure 10 and Figure 11 As shown, the plunger spring feeding mechanism 2 includes a spring distributing mechanism 21 and a gripping mechanism 22. The spring distributing mechanism 21 includes a first vibratory plate 211, a distributing component 212, and a first rotary positioning component 213. The first vibratory plate 211 and the distributing component 212 are connected by a first transport pipe 214. The first rotary positioning component 213 includes a first rotating seat 2131 and a first fixed seat 2132 surrounding the first rotating seat 2131. The first rotating seat 2131 is rotatable relative to the first fixed seat 2132. The rotating base 2131 has multiple plunger spring placement slots 2133 evenly distributed around its periphery. The first fixed base 2132 is provided with a first feed port 2134. The material distribution component 212 is provided with a push plate 2121 corresponding to the first feed port 2134. The push plate 2121 can move in a direction close to or away from the first feed port 2134 to push the plunger spring from the first feed port 2134 into the plunger spring placement slot 2133. The gripping mechanism 22 is used to move the plunger springs in the multiple plunger spring placement slots 2133 to the plunger seat to be assembled.

[0062] Using the plunger spring feeding mechanism 2 provided in this embodiment, the plunger springs are fed from the first vibrating plate 211 through the first transport pipe 214 into the material distribution component 212. After being distributed by the material distribution component 212, the push plate 2121 moves along the direction close to the first feed port 2134, pushing the plunger springs into the plunger spring placement slot 2133 of the first rotating seat 2131. The first rotating seat 2131 rotates relative to the first fixed seat 2132 until the next plunger spring placement slot 2133 corresponds to the first feed port 2134. The push plate 2121 pushes the next plunger spring into the plunger spring placement slot 2133 until all the plunger spring placement slots 2133 in the first rotating seat 2131 are filled. The gripping mechanism 22 moves the multiple plunger springs into the plunger seat to be assembled.

[0063] The automatic sorting and conveying of plunger springs is achieved through the cooperation of the first vibratory feeder 211 and the material distribution component 212, avoiding the confusion and errors that may occur in traditional manual operation. The design of the first rotary positioning component 213 enables the plunger springs to be placed and grasped in precise positions, thereby improving the overall assembly accuracy. The flexibility and efficiency of the grasping mechanism 22 further optimize the feeding process. This plunger spring feeding mechanism 2 can effectively improve the feeding efficiency of plunger springs, reduce manual intervention, and ensure the stability and consistency of the assembly process.

[0064] Based on the above technical solutions, such as Figure 11 and Figure 14-15As shown, the material distribution assembly 212 includes a first material distribution seat 2122, a first cylinder 2123, and a second cylinder 2124. The first material distribution seat 2122 has a first material distribution channel 2125 inside. The top end of the first material distribution channel 2125 is connected to the first transport pipe 214. The bottom end of the first material distribution channel 2125 has a discharge port 2126. The discharge port 2126 is correspondingly arranged with the first inlet port 2134. The first cylinder 2123 and the second cylinder 2124 are sequentially inserted into the side wall of the first material distribution seat 2122 in the vertical direction. Both the first cylinder 2123 and the second cylinder 2124 can move in a direction perpendicular to the extension of the first material distribution channel 2125.

[0065] Furthermore, the free height of the plunger spring is Hf, and the height between the first cylinder 2123 and the second cylinder 2124 is H, where Hf < H < 2Hf.

[0066] like Figure 15 As shown, when multiple plunger springs enter the first material distribution channel 2125 from the first vibrating plate 211 through the first conveying pipe 214, the initial state of the first cylinder 2123 is that it extends to the inner wall of the first material distribution channel 2125 to block all the plunger springs falling into the first material distribution channel 2125. When the plunger springs fall to contact the extended first cylinder 2123, the second cylinder 2124 extends. When the height H between the first cylinder 2123 and the second cylinder 2124 is in the range of Hf < H < 2Hf, the second cylinder... When cylinder 2124 extends, it presses down on the second plunger spring counted from bottom to top. The first cylinder 2123 retracts, and the first plunger spring counted from bottom to top (the lowest) falls to the bottom of the first distribution seat 2122. The push plate 2121 is located on the side of the plunger spring furthest from the discharge port 2126. The push plate 2121 moves towards the discharge port 2126, pushing the plunger spring out of the discharge port 2126 and into the corresponding plunger spring placement slot 2133 through the first feed port 2134. The push plate 2121 then retracts. At this time, the first cylinder 2123 extends, the second cylinder 2124 retracts, and the plunger spring falls to the first cylinder 2123. The second cylinder 2124 extends, pressing down on the plunger spring at the corresponding height. The first cylinder 2123 retracts, and the lowest plunger spring falls. The push plate 2121 pushes it into the plunger spring placement slot 2133, and so on, sequentially completing the distribution of subsequent plunger springs.

[0067] Optionally, there are multiple material distribution components 212, which can simultaneously distribute multiple sets of plunger springs.

[0068] Furthermore, the distribution positions of the multiple mounting holes of the plunger seat correspond to the distribution positions of the multiple plunger spring placement slots 2133.

[0069] Once the multiple plunger spring placement slots 2133 in the rotating seat are full, the gripping mechanism 22 grips multiple plunger springs and moves them simultaneously into the plunger seat, ensuring that each plunger spring accurately falls into the corresponding mounting hole, thereby achieving efficient and accurate assembly operations.

[0070] Based on the above technical solutions, such as Figure 11 and Figure 16 As shown, the material distribution assembly 212 further includes a third cylinder 2127, which is located on one side of the first material distribution seat 2122 and passes through the side wall of the first material distribution seat 2122. The end of the third cylinder 2127 is connected to a first push rod 2128.

[0071] Furthermore, the height HT of the end of the first push rod 2128 is higher than the height H1 of the first cylinder 2123, and the height HT of the end of the first push rod 2128 is less than H1 + Hf.

[0072] When multiple plunger springs enter the first distribution channel 2125, the first cylinder 2123 extends to block them, and the second cylinder 2124 extends to press down on the plunger springs at the corresponding height. The first cylinder 2123 retracts. At this point, it is expected that the lowest plunger spring will fall to the bottom of the first distribution seat 2122. If the lowest plunger spring gets stuck with the plunger spring above it, the third cylinder 2127 drives the first push rod 2128 to push the lowest plunger spring down, ensuring the smooth progress of the distribution process. The height HT of the end of the first push rod 2128 is designed to be higher than the height H1 of the first cylinder 2123, but lower than the sum of H1 and the free height Hf of the plunger spring. This setting can effectively avoid interference with the upper plunger springs, while ensuring that the first push rod 2128 can accurately act on the lowest plunger spring. Through the auxiliary action of the third cylinder 2127, the reliability and efficiency of the distribution are further improved, and the risk of equipment downtime or failure due to spring jamming is reduced.

[0073] The push plate 2121 is provided with a fourth cylinder 2129, which is connected to the push plate 2121 and is used to drive the push plate 2121 to move in a direction close to the first fixed seat 2132.

[0074] Furthermore, such as Figure 11 As shown, the first rotary positioning assembly 213 also includes a second sensor 2135, which is inserted through the side wall of the first fixed seat 2132, and the end of the second sensor 2135 is positioned toward the plunger spring placement groove 2133.

[0075] After a spring is placed in the plunger spring placement slot 2133, the first rotating seat 2131 rotates relative to the first fixed seat 2132, rotating the plunger spring placement slot 2133 to correspond with the second sensor 2135. The second sensor 2135 detects whether there is a spring in the plunger spring placement slot 2133. If a spring is detected in the plunger spring placement slot 2133, the material distribution process continues to the next plunger spring placement slot 2133. If no spring is detected, the second sensor 2135 sends a signal, and the first rotating seat 2131 rotates back, controlling the material distribution component 212 to perform the material distribution operation again, ensuring that a plunger spring can be accurately placed in each plunger spring placement slot 2133, further improving the reliability and accuracy of the entire material feeding process.

[0076] Based on the above technical solutions, such as Figure 11 As shown, the first rotary positioning component 213 further includes a second drive motor 2136, which is connected to the first rotary seat 2131 to drive the first rotary seat 2131 to rotate.

[0077] In this embodiment, as Figure 11 As shown, the spring-loaded material distribution mechanism 21 further includes a second base 215, the second base 215 is provided with a first fixed platform 216, the material distribution component 212 and the first rotary positioning component 213 are fixed on the first fixed platform 216. Specifically, the first material distribution seat 2122 is provided on the first fixed platform 216, the first fixed seat 2132 is provided on the first fixed platform 216, the second drive motor 2136 is provided below the first fixed platform 216, the second drive motor 2136 is fixed to the first fixed plate 2161, the first fixed plate 2161 is connected to the first fixed platform 216 through a plurality of first connecting legs 2162, the first rotary seat 2131 is provided with a first rotary shaft 2163, and the second drive motor 2136 is connected to the first rotary shaft 2163 through a second coupling.

[0078] Furthermore, such as Figure 12 and Figure 13 As shown, the first rotating shaft 2163 is provided with a first extension plate 2165, and the first rotating positioning assembly 213 also includes a third sensor 2166. The third sensor 2166 is provided with a detection groove, which is set towards the extension plate. The third sensor 2166 is used to detect whether the first rotating seat 2131 has rotated one revolution. When the extension plate rotates with the rotating shaft, it starts to pass through the detection groove for the first time. It continues to rotate until it passes through the detection groove for the second time, indicating that the first rotating seat 2131 has completed one revolution and the multiple plunger spring placement slots 2133 of the first rotating seat 2131 have been placed.

[0079] Optionally, there may be multiple first rotary positioning components 213, and multiple first rotary positioning components 213 may cooperate with multiple material dispensing components 212.

[0080] Based on the above technical solutions, such as Figure 17 As shown, the gripping mechanism 22 includes a first horizontal drive mechanism 221, a first vertical drive mechanism 222, and a gripping member 223. The first vertical drive mechanism 222 is disposed on the first horizontal drive mechanism 221, and the gripping member 223 is disposed on the first vertical drive mechanism 222. The gripping member 223 is correspondingly disposed with the first rotation positioning component 213.

[0081] Specifically, the first horizontal drive mechanism 221 can drive the first vertical drive mechanism 222 and the gripper 223 to move horizontally, thereby switching the position of the gripper 223 between the first rotary positioning assembly 213 and the plunger seat. The first vertical drive mechanism 222 is responsible for controlling the lifting and lowering action of the gripper 223. The first horizontal drive mechanism 221 and the first vertical drive mechanism 222 cooperate to ensure that the gripper 223 can accurately remove the plunger spring from the plunger spring placement slot 2133 on the first rotary seat 2131 and place it into the mounting hole of the plunger seat. Both the first horizontal drive mechanism 221 and the first vertical drive mechanism 222 are driven by high-precision servo motors in conjunction with slide rails to ensure stability and positioning accuracy during the gripping process. Through the coordinated work of the first horizontal drive mechanism 221, the first vertical drive mechanism 222 and the gripper 223, the gripping mechanism 22 can efficiently complete the synchronous transfer of multiple plunger springs, significantly improving the overall feeding efficiency.

[0082] Furthermore, such as Figure 18 As shown, the gripper 223 includes a second fixing part 2231 and an airbag part 2232. The airbag part 2232 is located at the center of the second fixing part 2231. The second fixing part 2231 is provided with a plurality of gripping grooves 2233. The airbag part 2232 can expand or shrink in the direction of approaching or moving away from the plurality of gripping grooves 2233 to grip and release a plurality of plunger springs.

[0083] Specifically, the first vertical drive mechanism 222 is provided with a fixing plate, the second fixing part 2231 is fixed to the fixing plate, the second fixing part 2231 of the gripping member 223 is arranged opposite to the first fixing seat 2132 of the first rotary positioning assembly 213, and the distribution positions of the multiple gripping slots 2233 correspond to the distribution positions of the multiple plunger spring placement slots 2133.

[0084] When the airbag 2232 is in an uninflated state, the gripping slot 2233 remains open, facilitating the entry and exit of the plunger springs. During the gripping process, the first horizontal drive mechanism 221 adjusts the gripper 223 to move above the plunger spring placement slot 2133 of the first rotating seat 2131, aligning the plunger spring placement slot 2133 with the gripping slot 2233. The first vertical drive mechanism 222 lowers the gripper 223 until the top portion of the plunger spring enters the gripping slot 2233. The airbag 2232 begins to inflate, applying pressure to multiple gripping slots 2233, thereby firmly securing multiple plunger springs. After the gripping is completed, the first vertical drive mechanism 222 lifts the gripper 223, and the first horizontal drive mechanism 221 moves it above the mounting hole of the plunger seat. The first vertical drive mechanism 222 then descends, causing the airbag 2232 to deflate and shrink, releasing the plunger springs and allowing them to fall precisely into the corresponding mounting holes. Through the elastic deformation of the air bladder 2232 and the controllable pressure adjustment, this design effectively avoids damage to the surface of the plunger spring while ensuring stability during gripping and placement. Furthermore, the structural design of the gripper 223 enables the simultaneous gripping of multiple plunger springs in a single operation, further improving assembly efficiency and precision.

[0085] Optionally, there are multiple gripping members 223, which cooperate with multiple first rotary positioning components 213 to simultaneously grip multiple sets of plunger springs.

[0086] Based on the above technical solutions, such as Figure 19 As shown, the plunger spring feeding mechanism 2 also includes a guide mechanism 23, which is located above the plunger seat. The guide mechanism 23 has multiple guide holes 231, and the distribution positions of the multiple guide holes 231 correspond to the distribution positions of the multiple mounting holes.

[0087] The guide mechanism 23 is designed to effectively guide the plunger spring to accurately fall into the mounting hole of the plunger seat, avoiding assembly failure or damage due to positional deviation. Specifically, the inner diameter of the guide hole 231 is slightly larger than the outer diameter of the plunger spring, forming a certain clearance fit to ensure that the plunger spring is properly constrained and guided during its descent. By setting up the guide mechanism 23, the stability and reliability of the entire feeding process are further improved, while reducing the need for manual intervention and significantly improving assembly efficiency and product quality consistency.

[0088] Furthermore, such as Figure 19 As shown, the guiding mechanism 23 includes multiple adjustable support legs 232 and a guide plate 233. The multiple adjustable support legs 232 are supported on the guide plate 233, and multiple guide holes 231 are provided on the guide plate 233.

[0089] The adjustable support legs 232 allow the guide plate 233 to be flexibly adjusted in height and angle according to actual needs, thus adapting to plunger seats of different sizes and specifications. Adjusting the support legs ensures that the guide hole 231 and the mounting hole of the plunger seat remain precisely aligned, further improving the accuracy and adaptability of the assembly process. The adjustable support legs 232 also enhance the equipment's versatility, enabling quick switching to different production tasks without the need for additional replacement of the guide mechanism 23, thereby reducing production costs and improving work efficiency. In actual operation, the adjustment device of the guide mechanism 23 is equipped with a locking function to ensure secure fixation after adjustment, preventing positional displacement due to vibration or external forces, further guaranteeing the stability and reliability of the feeding process.

[0090] Combination Figure 20 and Figure 21 As shown, this embodiment of the disclosure provides a plunger gasket mounting mechanism 3, including a gasket dispensing mechanism 31 and an adsorption mechanism 32. The gasket dispensing mechanism 31 includes a second vibratory plate 311, a push rod assembly 312, and a second rotary positioning assembly 313. The second vibratory plate 311 and the push rod assembly 312 are connected by a second transport pipe 314. The second rotary positioning assembly 313 includes a second rotating seat 3131 and a second fixed seat 3132 surrounding the second rotating seat 3131. The second rotating seat 3131 is rotatable relative to the second fixed seat 3132. The second rotating seat 3131 has a plurality of plunger gasket placement slots 3133 evenly distributed around its periphery. The second fixed seat 3132 is provided with a second feed port 3134. The push rod assembly 312 is provided with a push rod 3121 corresponding to the second feed port 3134. The push rod 3121 can move in a direction close to or away from the second feed port 3134 to push the plunger gasket from the second feed port 3134 into the plunger gasket placement slot 3133. The adsorption mechanism 32 is used to move the plunger gaskets in the plurality of plunger gasket placement slots 3133 into the plunger seat 16 to be installed.

[0091] Using the plunger gasket mounting mechanism 3 provided in this embodiment, the plunger gasket enters the push rod assembly 312 through the second transport pipe 314 from the second vibrating plate 311. After being distributed by the push rod assembly 312, the push rod 3121 moves along the direction close to the second feed port 3134, pushing the plunger gasket into the plunger gasket placement groove 3133 of the second rotating seat 3131. The second rotating seat 3131 rotates relative to the second fixed seat 3132 until the next plunger gasket placement groove 3133 corresponds to the second feed port 3134. The push rod 3121 pushes the next plunger gasket into the plunger gasket placement groove 3133 until all the plunger gasket placement grooves 3133 in the second rotating seat 3131 are filled. The adsorption mechanism 32 moves the multiple plunger gaskets into the plunger seat 16 to be assembled.

[0092] The automatic sorting and conveying of plunger gaskets is achieved through the cooperation of the second vibratory plate 311 and the push rod assembly 312, avoiding the confusion and errors that may occur in traditional manual operation. The design of the second rotary positioning assembly 313 allows the plunger gaskets to be placed and picked up in precise positions, thereby improving the overall assembly accuracy. The flexibility and efficiency of the adsorption mechanism 32 further optimize the feeding process. This plunger gasket feeding mechanism can effectively improve the feeding efficiency of plunger gaskets, reduce manual intervention, and ensure the stability and consistency of the assembly process.

[0093] Based on the above technical solutions, such as Figure 21 and Figure 22 As shown, the push rod assembly 312 includes a second material distribution seat 3122, a first drive cylinder 3123, and a connecting block 3124. The first drive cylinder 3123 is connected to the push rod 3121 through the connecting block 3124. The end of the push rod 3121 passes through the second material distribution seat 3122. The second material distribution seat 3122 is provided with a second material distribution channel 3125. The first end of the second material distribution channel 3125 is connected to the second transport pipe 314. The second end of the second material distribution channel 3125 is connected to the end of the push rod 3121. The third end of the second material distribution channel 3125 is connected to the second feed port 3134. The second end and the third end are arranged opposite to each other.

[0094] Specifically, such as Figure 21 and Figure 22 As shown, the plunger gasket is transported sequentially from the second vibratory plate 311 to the second distribution seat 3122 via the second transport pipe 314, and enters the T-shaped or similar T-shaped second distribution channel 3125. The second distribution seat 3122 is equipped with a detection switch. When the presence of the plunger gasket is detected, the first drive cylinder 3123 drives the push rod 3121 to move towards the direction close to the second feed port 3134, pushing the plunger gasket along the second distribution channel 3125 through the second feed port 3134 into the second vibratory plate. Within the plunger gasket placement slot 3133 of the rotary seat 3131, the second rotary seat 3131 rotates relative to the second fixed seat 3132 until the next plunger gasket placement slot 3133 aligns with the second feed inlet 3134. The next plunger gasket enters the second distribution channel 3125 through the second transport pipe 314. The push rod 3121 pushes the plunger gasket into the second feed inlet 3134 and reaches the plunger gasket placement slot 3133. This process is repeated to place multiple plunger gaskets. Preferably, the extension direction of the push rod 3121 is perpendicular to the extension direction of the second transport pipe 314.

[0095] Optionally, there may be multiple push rod assemblies 312, which can simultaneously distribute multiple sets of plunger gaskets.

[0096] Furthermore, such as Figure 27 and Figure 28 As shown, the distribution positions of the plurality of mounting holes 161 of the plunger seat 16 correspond to the distribution positions of the plurality of plunger gasket placement grooves 3133.

[0097] When the multiple plunger gasket placement slots 3133 in the second rotating seat 3131 are full, the adsorption mechanism 32 picks up multiple plunger gaskets and moves them into the plunger seat 16 at the same time, ensuring that each plunger gasket is accurately installed into the corresponding mounting hole 161, thereby achieving efficient and accurate assembly operation.

[0098] Based on the above technical solutions, such as Figure 22 As shown, the second rotary positioning component 313 further includes a third drive motor 3135, which is connected to the second rotary seat 3131 to drive the second rotary seat 3131 to rotate.

[0099] In this embodiment, as Figure 22-23 As shown, the gasket dispensing mechanism 31 further includes a third base 315, the third base 315 is provided with a second fixed platform 316, the push rod assembly 312 and the second rotation positioning assembly 313 are fixed on the second fixed platform 316. Specifically, the second dispensing seat 3122 is provided on the second fixed platform 316, the second fixed seat 3132 is provided on the second fixed platform 316, the third drive motor 3135 is provided below the second fixed platform 316, the third drive motor 3135 is fixed to the second fixed plate 3161, the second fixed plate 3161 is connected to the second fixed platform 316 through multiple second connecting legs 3162, the second rotating seat 3131 is provided with a second rotating shaft 3163, and the third drive motor 3135 is connected to the second rotating shaft 3163 through a third coupling 3164.

[0100] Optionally, there may be multiple second rotary positioning components 313, which cooperate with multiple push rod components 312.

[0101] Furthermore, such as Figure 24 As shown, the second rotating seat 3131 is provided with a second rotating shaft 3163, the second rotating shaft 3163 is provided with a second extension plate 3165, and the second rotating positioning assembly 313 further includes a fourth sensor 3166. The fourth sensor 3166 is provided with a detection groove 3167, the detection groove 3167 is disposed toward the extension plate, and the fourth sensor 3166 is used to detect whether the extension plate has rotated one revolution.

[0102] When the second extension plate 3165 rotates with the second rotating shaft 3163, it starts to rotate after passing the detection groove 3167 for the first time. When it rotates to pass the detection groove 3167 for the second time, it indicates that the second rotating seat 3131 has completed one revolution and the multiple plunger gasket placement slots 3133 of the second rotating seat 3131 have been placed.

[0103] Based on the above technical solutions, such as Figure 25 As shown, the adsorption mechanism 32 includes a second horizontal driving mechanism 321, a second vertical driving mechanism 322, and an adsorption member 323. The second vertical driving mechanism 322 is disposed on the second horizontal driving mechanism 321, and the adsorption member 323 is disposed on the second vertical driving mechanism 322. The adsorption member 323 is disposed in accordance with the second rotary positioning component 313 along the movement direction of the second horizontal driving mechanism 321.

[0104] Specifically, the second horizontal drive mechanism 321 can drive the second vertical drive mechanism 322 and the adsorption member 323 to move horizontally, thereby switching the position of the adsorption member 323 between the second rotary positioning assembly 313 and the plunger seat 16. The second vertical drive mechanism 322 is responsible for controlling the lifting and lowering of the adsorption member 323. The second horizontal drive mechanism 321 and the second vertical drive mechanism 322 cooperate to ensure that the adsorption member 323 can accurately remove the plunger pad from the plunger pad placement groove 3133 on the second rotary seat 3131 and place it into the mounting hole 161 of the plunger seat 16. Both the second horizontal drive mechanism 321 and the second vertical drive mechanism 322 are driven by high-precision servo motors in conjunction with slide rails to ensure stability and positioning accuracy during the suction process. Through the coordinated work of the second horizontal drive mechanism 321, the second vertical drive mechanism 322, and the adsorption member 323, the adsorption mechanism 32 can efficiently complete the synchronous transfer of multiple plunger pads, significantly improving the overall feeding efficiency.

[0105] Furthermore, such as Figure 25 and Figure 26 As shown, the vertical drive mechanism is provided with a first fixed bracket 3221, and the adsorption member 323 includes a plurality of adsorption heads 3231 and a drive air source 3232. The drive air source 3232 is connected to the plurality of adsorption heads 3231, and the plurality of adsorption heads 3231 and the drive air source 3232 are disposed on the first fixed bracket 3221.

[0106] Preferably, there are multiple driving air sources 3232, each connected one-to-one with a corresponding adsorption head 3231. This allows for independent control of the adsorption action of each adsorption head 3231, enabling precise gripping and release of multiple plunger pads. This design not only enhances the flexibility of the adsorption mechanism 32 but also allows for adjustment of the adsorption force according to actual needs, ensuring that the plunger pads do not shift or become damaged during transfer. Furthermore, the first fixed bracket 3221 has a stable structure, effectively supporting the multiple adsorption heads 3231 and driving air sources 3232, ensuring the reliability of the entire adsorption mechanism 32 during high-speed operation.

[0107] Based on the above technical solution, the distribution positions of the multiple adsorption heads 3231 correspond to the distribution positions of the multiple plunger gasket placement grooves 3133.

[0108] When all the plunger pad placement slots 3133 in the second rotating seat 3131 are filled, the adsorption member 323 adsorbs the plunger pads and moves them to the plunger seat 16. The distribution positions of the multiple adsorption heads 3231 correspond to the distribution positions of the multiple plunger pad placement slots 3133. During the adsorption process, it is ensured that each plunger pad can be accurately adsorbed, avoiding misalignment or omission.

[0109] In this embodiment, the top of the positioning pin 152 is provided with a magnet, such as Figure 28 As shown, when the adsorption head 3231 adsorbs the plunger gasket above the plunger seat 16, it moves downward until the plunger gasket is attracted by the magnet at the top of the positioning pin 152, and the adsorption head 3231 releases the suction force.

[0110] Furthermore, there are multiple gasket dispensing mechanisms 31 and multiple adsorption elements 323, with each adsorption element 323 corresponding to one of the multiple gasket dispensing mechanisms 31.

[0111] Multiple gasket dispensing mechanisms 31 cooperate with multiple adsorption elements 323 to simultaneously perform dispensing and adsorption operations on multiple sets of plunger gaskets, further improving overall work efficiency. Each gasket dispensing mechanism 31 and its corresponding adsorption element 323 work collaboratively to ensure that the process from dispensing to adsorption to assembly for each set of plunger gaskets is independent and efficient, avoiding mutual interference between different sets. Furthermore, the arrangement of multiple gasket dispensing mechanisms 31 and adsorption elements 323 can adapt to different production scales and flexibly adjust the workload to meet diverse feeding scenarios. This design not only improves equipment utilization but also significantly enhances the stability and consistency of the feeding process.

[0112] Based on the above technical solution, a direct vibration assembly is connected below the second transport pipe 314. When the plunger gasket is output from the second vibrating plate 311, the direct vibration assembly vibrates the plunger gasket and transmits it to the second distribution seat 3122.

[0113] Combination Figure 29 As shown, this embodiment of the present disclosure provides a plunger cap assembly mechanism 4, including a storage mechanism 41, a second transfer mechanism 42, and an auxiliary positioning mechanism 44. The storage mechanism 41 is provided with a plurality of positioning elements 411, and the plunger cap is disposed on the positioning elements 411. A spring 452 is installed in the mounting hole 161. The auxiliary positioning mechanism 44 is provided with an elastic adsorption element 441, which adsorbs onto one side of the spring 452. The second transfer mechanism 42 is used to move the plunger cap from the storage mechanism 41 to the plunger seat 16 to cover and assemble it on the outside of the spring 452.

[0114] Using the plunger cap assembly mechanism 4 provided in this embodiment, the plunger cap to be assembled is stored by a storage mechanism 41. Multiple mounting holes 161 of the plunger seat 16 are placed corresponding to multiple positioning pins 152. The clamping assembly 151 clamps and fixes the plunger seat 16. A spring 452 is installed in the mounting hole 161 of the plunger seat 16. The spring 452 is sleeved on the positioning pin 152. The elastic adsorption member 441 adsorbs on one side of the spring 452 to fix the position of the spring 452. The plunger cap is moved from the storage mechanism 41 to the plunger seat 16 by the second transfer mechanism 42 and is mounted on the spring 452.

[0115] The clamping assembly 151 and the positioning pin 152 work together to ensure the stability of the plunger seat 16 during assembly. The positioning pin 152 limits the position of the spring 452 to a certain extent, while the elastic adsorption component 441 further enhances the fixing effect of the spring 452, avoiding assembly failure due to positional misalignment and improving assembly accuracy. The second transfer mechanism 42 realizes the automated transfer and assembly of the plunger cap, significantly reducing the difficulty of operation and time cost. The multi-positioning component 411 of the storage mechanism 41 can accommodate multiple plunger caps, improving continuous operation capability. This plunger cap assembly mechanism 4 can effectively improve assembly efficiency, reduce manual intervention, and ensure assembly accuracy.

[0116] Based on the above technical solutions, such as Figure 30 As shown, the storage mechanism 41 includes an upper storage assembly and a lower storage assembly. The upper storage assembly includes a first drive slide rail 412 and a first storage plate 413 disposed on the first drive slide rail 412. The lower storage assembly includes a second drive slide rail 414 and a second storage plate 415 disposed on the second drive slide rail 414. The first storage plate 413 is disposed above the second storage plate 415. The first drive slide rail 412 and the second drive slide rail 414 extend in a direction close to the clamping and positioning mechanism 15. The positioning member 411 is disposed on the first storage plate 413 and the second storage plate 415.

[0117] The first storage plate 413 and the second storage plate 415 are driven independently by the first drive slide rail 412 and the second drive slide rail 414, respectively, thereby sequentially conveying the plunger caps to be assembled to the working range of the transfer mechanism. The layered design of the upper and lower storage components effectively utilizes space, increases storage capacity, and avoids mutual interference between the plunger caps. In addition, the extension direction of the first drive slide rail 412 and the second drive slide rail 414 matches the position of the clamping and positioning mechanism 15, ensuring that the plunger caps can be accurately grasped by the transfer mechanism and transferred to the assembly position.

[0118] Specifically, in this embodiment, there are two first drive slide rails 412 and two second drive slide rails 414. The two second drive slide rails 414 are located inside the two first drive slide rails 412. Each of the two first drive slide rails 412 is provided with a support plate 416. The first storage plate 413 is supported on the support plate 416. The storage mechanism 41 also includes a control component, which controls the first storage plate 413 and the second storage plate 415 to move on the first drive slide rail 412 and the second drive slide rail 414 respectively. After all the plunger covers on the first storage plate 413 are assembled, the first storage plate 413 is controlled to move to the outside to replenish the plunger covers. After all the plunger covers on the second storage plate 415 are assembled, the first storage plate 413 is controlled to move to the inside to continue the assembly. Then the second storage plate 415 is controlled to move to the outside to replenish the plunger covers. Through the precise operation of the control component, the first storage plate 413 and the second storage plate 415 can work alternately to ensure that the assembly process is not interrupted due to the replenishment of plunger covers, thereby further improving the continuity and efficiency of the assembly.

[0119] Furthermore, the design of the support plate 416 enhances the stability of the first storage plate 413, preventing swaying or displacement during movement, thereby further improving the reliability of the plunger cap delivery. The internal and external layout of the two first drive slide rails 412 and the two second drive slide rails 414 optimizes the overall structural compactness and reduces the space occupied by the equipment. To further improve operational convenience, the positioning components 411 of both the first storage plate 413 and the second storage plate 415 adopt an adjustable structure to adapt to plunger caps of different specifications, enhancing the versatility of the equipment.

[0120] Specifically, the positioning element 411 can be a positioning pin or a positioning block, as long as it can be adapted to the plunger cover to position the plunger cover, and there is no limitation here.

[0121] Optionally, the number of the storage mechanisms 41 is multiple.

[0122] Based on the above technical solutions, such as Figure 29As shown, the second transfer mechanism 42 includes a second X-axis drive mechanism 421, a second Y-axis drive mechanism 422, a second Z-axis drive mechanism 423, and a second moving head 424. The second X-axis drive mechanism 421 is disposed on the second Y-axis drive mechanism 422, the second Z-axis drive mechanism 423 is disposed on the second X-axis drive mechanism 421, and the second moving head 424 is disposed at the end of the second Z-axis drive mechanism 423.

[0123] Specifically, the second X-axis drive mechanism 421, the second Y-axis drive mechanism 422, and the second Z-axis drive mechanism 423 can drive the moving head to move along the X, Y, and Z directions, thereby achieving precise transfer of the plunger cap between the storage mechanism 41, the clamping and positioning mechanism 15, and the plunger seat 16. The second X-axis drive mechanism 421, the second Y-axis drive mechanism 422, and the second Z-axis drive mechanism 423 all employ high-precision servo motors in conjunction with slide rails to ensure stability and positioning accuracy during the transfer process.

[0124] Optionally, such as Figure 33 As shown, there can be multiple second X-axis drive mechanisms 421, second Y-axis drive mechanisms 422, and second Z-axis drive mechanisms 423. Multiple second Z-axis drive mechanisms 423 are provided with multiple second moving heads 424, and multiple second moving heads 424 are provided with multiple material storage mechanisms 41. Multiple plunger covers can be moved simultaneously and moved to the plunger seats 16 of the corresponding multiple clamping and positioning mechanisms 15.

[0125] Furthermore, such as Figure 31 As shown, a floating compensation component 425 is provided between the second moving head 424 and the second Z-axis drive mechanism 423.

[0126] Specifically, the upper edge of the mounting hole 161 of the plunger seat 16 has a chamfered structure. When the second moving head 424 moves the plunger cover from the storage mechanism 41 to the plunger seat 16 to be assembled along the X and Y axes, the plunger cover corresponds vertically to the mounting hole 161 below. The second moving head 424 moves downward along the Z axis, preparing to insert into the mounting hole 161. When the bottom end of the plunger cover meets the edge of the mounting hole 161, due to the possible slight positional deviation between the plunger cover and the mounting hole 161, the floating compensation component 425 can play a role in this process. Through its elastic or adjustable structural design, it allows the second moving head 424 to make fine adjustments within a certain range, thereby automatically correcting the positional deviation and ensuring that the plunger cover can be smoothly inserted into the mounting hole 161. This design not only improves the success rate of assembly but also effectively reduces the risk of part damage caused by hard contact. In this way, the second transfer mechanism 42 can achieve a more stable and reliable assembly operation while ensuring high precision. Specifically, the floating compensation component 425 can be a combination of an air-driven component and an elastic element; this is a standard existing structure, and its specific structure will not be described in detail here. Optionally, a rotary motor is provided between the floating compensation component 425 and the Z-axis drive mechanism 423. The rotary motor can drive the floating compensation component 425 and the second moving head 424 to rotate, avoiding interference between the second moving head 424 and other already installed plunger caps during installation. This is suitable for assembling plunger caps on various types of plunger seats.

[0127] Based on the above technical solutions, such as Figure 31 As shown, the second moving head 424 includes a first moving arm 4241 and a second moving arm 4242 arranged opposite to each other. The end of the second Z-axis drive mechanism is provided with a first horizontal drive member 426 and a first slide rail 427. The first slide rail 427 is disposed on the first horizontal drive member 426. The first moving arm 4241 and the second moving arm 4242 can move closer or further away from each other along the first slide rail 427.

[0128] Specifically, the relative movement of the first moving arm 4241 and the second moving arm 4242 is controlled by the first horizontal drive member 426. The first horizontal drive member 426 drives the first moving arm 4241 and the second moving arm 4242 to achieve synchronous or independent movements through the first slide rail 427, so that the moving head can flexibly adjust the clamping range to adapt to plunger caps of different sizes, thereby improving the versatility and operational flexibility of the equipment. In actual operation, when the plunger cap is transferred from the storage mechanism 41 to the plunger seat 16 to be assembled, the first moving arm 4241 and the second moving arm 4242 can quickly unfold or close under the action of the first horizontal drive member 426 to complete the precise gripping and releasing action. Combined with the vertical movement of the Z-axis drive mechanism, an efficient automated assembly process is achieved.

[0129] Furthermore, such as Figure 31 As shown, the ends of the first moving arm 4241 and the second moving arm 4242 are both provided with arc-shaped plates 428, and the curvature of the arc-shaped plates 428 is adapted to the plunger cover.

[0130] Specifically, the arc-shaped plate 428 is designed to better conform to the outer surface of the plunger cap, ensuring uniform contact pressure during gripping and preventing deformation or damage to the plunger cap due to excessive localized force. The arc-shaped plate 428 is made of a highly wear-resistant, high-friction coefficient material, further enhancing the stability and reliability of the gripping process. Furthermore, the inner side of the arc-shaped plate 428 features a flexible protective layer that effectively protects the plunger cap surface during clamping, preventing damage.

[0131] Based on the above technical solutions, such as Figure 32 As shown, the auxiliary positioning mechanism 44 is provided with a fourth base 442, a third vertical drive mechanism 443, and a first clamping arm 444 and a second clamping arm 445 arranged opposite to each other. The third vertical drive mechanism 443 is located on the base, and the first clamping arm 444 and the second clamping arm 445 are located on the third vertical drive mechanism 443. The first clamping arm 444 and the second clamping arm 445 extend in a direction close to the clamping and positioning mechanism 15. The elastic adsorption member 441 is located inside the first clamping arm 444 and the second clamping arm 445.

[0132] Specifically, the third vertical drive mechanism 443 can drive the first clamping arm 444 and the second clamping arm 445 to move up and down, thereby adjusting the position of the elastic adsorption member 441 so that it is precisely aligned with one side of the spring 452. The auxiliary positioning mechanism 44 works in conjunction with the clamping and positioning mechanism 15. After the clamping and positioning mechanism 15 fixes the plunger seat 16, the auxiliary positioning mechanism 44 uses the elastic adsorption member 441 to fine-tune and reposition the spring 452, eliminating potential problems caused by initial placement deviations. This not only greatly improves assembly accuracy but also significantly reduces the possibility of human intervention and improves assembly efficiency.

[0133] Furthermore, such as Figure 32 As shown, both the first clamping arm 444 and the second clamping arm 445 have multiple elastic suction elements 441 on their inner sides, and the multiple elastic suction elements 441 are correspondingly arranged with multiple springs 452. The arrangement of the multiple elastic suction elements 441 corresponds one-to-one with the multiple springs 452 on the plunger seat 16, ensuring that each spring 452 can be accurately positioned and fixed.

[0134] Furthermore, the elastic adsorption member 441 has a magnetic part at one end near the spring 452.

[0135] Specifically, a magnet is provided at the end of the elastic adsorption component 441 near the spring 452. The magnet can firmly adsorb the spring 452, further enhancing the stability of the spring 452 during assembly. The first clamping arm 444 and the second clamping arm 445 can move up and down under the control of the vertical drive component, thereby adjusting the distance between the elastic adsorption component 441 and the spring 452. To further optimize operational accuracy, the vertical drive component adopts a high-precision servo motor, which can achieve precise displacement control and ensure accurate alignment between the elastic adsorption component 441 and the spring 452.

[0136] Based on the above technical solutions, such as Figure 32 As shown, the third vertical drive mechanism 443 is provided with a second horizontal drive member 446, the second horizontal drive member 446 is provided with a second slide rail 447, the second slide rail 447 is provided with a slider 448, and the first clamping arm 444 and the second clamping arm 445 are both fixedly connected to the slider 448.

[0137] Specifically, the first clamping arm 444 and the second clamping arm 445, through the cooperation of the slider 448 and the second slide rail 447, can move precisely in the horizontal direction. The second horizontal drive member 446 controls the slider 448 to slide along the second slide rail 447, thereby driving the first clamping arm 444 and the second clamping arm 445 to adjust the relative positions between the multiple elastic adsorption members 441 and the spring 452, achieving further fine-tuning of the position of the spring 452. This design not only enhances the flexibility of the auxiliary positioning mechanism 44, but also improves the accuracy of the alignment between the elastic adsorption members 441 and the spring 452.

[0138] Furthermore, the slider 448 and the second slide rail 447 are coupled using a high-precision ball screw structure to ensure smooth and offset-free movement. The second horizontal drive component 446 employs a high-precision servo motor, enabling precise displacement control to meet the assembly requirements of springs 452 of different specifications. Through the coordinated operation of the vertical drive component and the second horizontal drive component 446, the first clamping arm 444 and the second clamping arm 445 can be flexibly adjusted in three-dimensional space, providing optimal positioning for the spring 452.

[0139] Combination Figure 34 and Figure 35As shown, the plunger pump assembly system also includes a plunger pump gasket detection mechanism 5. The plunger pump gasket detection mechanism 5 includes a drive assembly 51 and a detection assembly 52. ​​The detection assembly 52 is connected to the drive assembly 51. The detection assembly 52 includes a main body 521, a clamping member 522, and a height detection part 523. The height detection part 523 passes through the main body 521, and the clamping member 522 is sleeved on the height detection part 523. A second elastic member 524 is provided between the clamping member 522 and the main body 521. A spring 452, a gasket 543, and a cover 544 are sequentially provided in the plurality of mounting holes 161 of the plunger seat 16. The clamping member 522 and the height detection part 523 are both oriented toward the plunger pump. The clamping member 522 can move relative to the main body 521 in a direction closer to or farther from the plunger pump.

[0140] The plunger pump gasket detection mechanism 5 provided in this embodiment uses a drive assembly 51 to drive the detection assembly 52 to move in a direction closer to or away from the plunger pump. When the main body 521 moves towards the plunger pump, the pressing head gradually approaches the cover 544 on the mounting hole 161. With the assistance of the second elastic element 524, it presses the cover 544 downward, so that the cover 544 is in the installed position. At this time, the height detection unit 523 detects the height of the cover 544 and determines whether the detected height of the cover 544 is equal to the standard height. When the detected height is equal to the standard height, it means that the gasket 543 has been installed inside the mounting hole 161. When the detected height is less than the standard height, it means that the gasket 543 has not been installed inside the mounting hole 161. This allows for quick and accurate identification of whether the plunger pump is missing a gasket 543, improving detection efficiency and accuracy. Furthermore, by ensuring that multiple positioning pins 152 in the clamping and positioning mechanism 15 correspond one-to-one with the mounting holes 161 of the plunger pump, the stability and precise positioning of the plunger pump during the testing process can be ensured, avoiding testing errors caused by positional deviations. The linkage design between the drive assembly 51 and the testing assembly 52 further optimizes the operation process, reduces manual intervention, and improves the overall automation level of the testing. This mechanism has a compact structure, is easy to operate, and is suitable for testing various specifications of plunger pump gaskets 543.

[0141] Based on the above technical solutions, such as Figure 36 and Figure 37 As shown, the main body 521 includes a third fixing plate 525, a mounting plate 526 and a clamping cover plate 527 arranged sequentially along the direction close to the plunger seat 16. The drive assembly 51 is connected to the third fixing plate 525. The mounting plate 526 is provided with a mounting cavity 5261. The height detection part 523 is fixedly inserted through the third fixing plate 525 and extends into the mounting cavity 5261. The clamping member 522 is provided in the mounting cavity 5261 and protrudes from the clamping cover plate 527.

[0142] Specifically, the third fixing plate 525 is used to connect the drive assembly 51, enabling the drive assembly 51 to drive the detection assembly 52. ​​The third fixing plate 525 is also used to fix the height detection part 523, ensuring the stability of the height detection part 523 and achieving accurate detection by the height detection part 523. The mounting cavity 5261 of the mounting plate 526 provides a precise mounting space for the height detection part 523 and the clamping member 522, while also protecting the internal components. The clamping cover plate 527 not only prevents the clamping member 522 from detaching from the mounting cavity 5261 during movement, but also further enhances the overall structural rigidity. The part of the clamping member 522 protruding from the clamping cover plate 527 is used to directly contact the cover 544 during the detection process, clamping the cover 544 and preventing detection errors caused by the cover 544 not being installed properly. In addition, the mounting plate 526 and the clamping cover plate 527 are connected through precision-machined positioning holes, ensuring the coaxiality between the components and further improving the accuracy of the detection.

[0143] Optionally, the height detection unit 523 may be a contactless sensor, and its working principle may include, but is not limited to, electromagnetic induction, photoelectric effect, ultrasonic wave or infrared light.

[0144] Furthermore, such as Figure 37 As shown, the bottom wall of the mounting cavity 5261 is provided with a first opening 5262, the clamping cover plate 527 is provided with a second opening 5271, a first limiting part 5272 is formed between the second opening 5271 and the first opening 5262, and the outer wall of the clamping member 522 is provided with a first limiting mating part 5221. The first limiting part 5272 and the first limiting mating part 5221 cooperate with each other so that the clamping member 522 is partially locked in the mounting cavity 5261.

[0145] Specifically, the size of the first opening 5262 is larger than the size of the second opening 5271, thereby forming a first limiting portion 5272. The clamping member 522 includes a first segment and a second segment. The outer wall of the first segment contacts the inner wall of the mounting cavity 5261. The second segment is disposed within the second opening 5271 and protrudes from the second opening 5271. The size of the first segment is larger than the size of the second segment, thereby forming a second limiting mating portion 5263. The cooperation between the first limiting portion 5272 and the first limiting mating portion 5221 can effectively limit the movement range of the clamping member 522 within the mounting cavity 5261, preventing the clamping member 522 from excessively extending or detaching from the mounting cavity 5261 due to the force of the second elastic member 524, thereby ensuring the stability and reliability of the clamping member 522 during the testing process.

[0146] Furthermore, such as Figure 37As shown, the inner wall of the clamping member 522 is provided with a second limiting part 5222, the top wall of the mounting cavity 5261 is provided with a second limiting mating part 5263, one end of the second elastic member 524 abuts against the second limiting part 5222, and the other end of the second elastic member 524 abuts against the second limiting mating part 5263.

[0147] Specifically, the size of the first segment of the clamping member 522 is larger than the size of the second segment, thereby forming a first limiting fit portion 5221 on the outside and a second limiting portion 5222 on the inside. The top wall of the mounting cavity 5261 is provided with a third opening. The top wall of the mounting cavity 5261, excluding the third opening, can serve as a second limiting fit portion 5263 to limit the top end of the second elastic member 524.

[0148] The second elastic element 524 provides a continuous elastic force to the clamping element 522, ensuring that the clamping element 522 maintains proper clamping of the cover 544 during the testing process. When the main body 521 moves towards the plunger pump, the clamping element 522 first contacts the cover 544 and gradually applies pressure under the action of the drive assembly 51, compressing the second elastic element 524 accordingly. The second elastic element 524 can not only adapt to covers 544 of different thicknesses but also effectively prevent damage to the cover 544 or other components of the plunger pump due to excessive pressure. In addition, the elastic restoring force of the second elastic element 524 helps the clamping element 522 to quickly reset after testing, thereby reducing operation waiting time and improving testing efficiency. Furthermore, the design of the second limiting part 5222 and the second limiting mating part 5263 makes the position of the second elastic element 524 in the mounting cavity 5261 more stable, avoiding possible displacement or tilting of the second elastic element 524 during long-term use.

[0149] Based on the above technical solution, there are multiple clamping parts 522 and height detection parts 523, and each clamping part 522 and height detection part 523 is respectively provided in a one-to-one correspondence with the mounting hole 161.

[0150] Specifically, the arrangement of multiple clamping components 522 and height detection units 523 enables simultaneous detection of multiple mounting holes 161 of the plunger pump, significantly improving detection efficiency. Each clamping component 522 works in conjunction with its corresponding height detection unit 523 to ensure that the state of the gasket 543 within each mounting hole 161 can be accurately identified. This one-to-one correspondence design not only reduces detection time but also improves the reliability of detection results, avoiding the accumulation of errors that may result from individual detection. Furthermore, the modular design of the multiple clamping components 522 and height detection units 523 makes the mechanism more adaptable, allowing for flexible configuration adjustments based on the number and layout of mounting holes 161 for different models of plunger pumps, thereby meeting the detection needs of various product specifications and improving versatility.

[0151] Based on the above technical solutions, such as Figure 35 and Figure 36 As shown, the drive assembly 51 includes a second drive cylinder 511 and a floating joint 512, and the third fixed plate 525 is provided with a connector 5251. The second drive cylinder 511, the floating joint 512 and the connector 5251 are connected in sequence.

[0152] Specifically, the second drive cylinder 511, acting as a power source, transmits driving force to the detection component 52 through the cooperation of the floating joint 512 and the connecting piece 5251, thereby enabling the detection component 52 to move precisely in the direction of approaching or moving away from the plunger pump. The floating joint 512 effectively compensates for assembly errors between the second drive cylinder 511 and the third fixed plate 525, avoiding stress concentration problems caused by insufficient machining or installation accuracy, and also reducing the impact of vibration on detection accuracy during movement. The connecting piece 5251 is fixedly connected to the third fixed plate 525 by bolts or other fastening methods, ensuring stable linkage between the drive component 51 and the detection component 52. In addition, the stroke of the second drive cylinder 511 can be precisely controlled by an adjustment device to adapt to the detection requirements of plunger pumps of different height specifications, further enhancing the flexibility and applicability of the detection mechanism.

[0153] Furthermore, such as Figure 35 As shown, the plunger pump gasket 543 detection mechanism 5 also includes a second fixed bracket 55, the second drive cylinder 511 is fixed to the second fixed bracket 55, the drive assembly 51 also includes a linear bearing 513 and a guide shaft 514, the linear bearing 513 is sleeved on the guide shaft 514, the linear bearing 513 is fixed to the second fixed bracket 55, and the bottom end of the guide shaft 514 is fixed to the mounting plate 526.

[0154] Specifically, the second fixed bracket 55 provides a stable support foundation for the entire testing mechanism, ensuring the overall stability of the mechanism during testing and avoiding testing errors caused by external forces or vibrations. The cooperative design of the linear bearing 513 and the guide shaft 514 further enhances the smoothness and accuracy of the movement of the testing component 52. The guide shaft 514, through its fixed connection to the mounting plate 526 at its bottom end, can effectively guide the testing component 52 to move linearly along a predetermined trajectory, reducing the possibility of deviation or wobbling. In addition, the use of the linear bearing 513 reduces the frictional resistance of the guide shaft 514 during movement, extending the service life of the components, while also ensuring the high efficiency of power transmission by the drive component 51.

[0155] Combination Figure 38 As shown, this disclosure provides an assembly method for a plunger pump, applied to an assembly system for a plunger pump as described in any of the above embodiments, comprising the following steps: S1, the plunger seat feeding mechanism feeds the plunger seat to the clamping and positioning mechanism, and the clamping and positioning mechanism clamps the plunger seat; S2, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the pre-positioning mechanism, and the pre-positioning mechanism positions and adjusts the placement position and angle of the plunger seat. The clamping and positioning mechanism continues to move along the guide rail. S3, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger spring feeding mechanism, the plunger spring feeding mechanism installs the spring into the preset position in the plunger seat, and the clamping and positioning mechanism continues to move along the guide rail; S4, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger gasket installation mechanism, the plunger gasket installation mechanism accurately installs the gasket into the preset position of the plunger seat, and the clamping and positioning mechanism continues to move along the guide rail; S5, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger cover assembly mechanism, and the plunger cover assembly mechanism assembles the plunger cover to the preset position of the plunger seat, which is sleeved on the spring and gasket, thus completing the assembly of the plunger pump. S6, the clamping and positioning mechanism moves along the guide rail to the plunger pump gasket detection mechanism. The plunger pump gasket detection mechanism determines whether the assembled plunger pump is missing a gasket. If the plunger pump is missing a gasket, the plunger pump is transferred to the scrap bin. If the plunger pump is not missing a gasket, the plunger pump is transferred back to the storage tray.

[0156] Based on the above technical solution, step S3 includes the following steps: S3.1, the clamping and positioning mechanism moves along the guide rail to the corresponding position of the plunger spring feeding mechanism, and the plunger spring enters the material distribution component through the first conveying pipe from the first vibrating plate. The material distribution component distributes the plunger spring. S3.2, the pusher plate moves along the direction close to the first feed port, pushing the plunger spring obtained from the material distribution to the plunger spring placement slot corresponding to the first rotating seat; S3.3, the first rotating seat rotates relative to the first fixed seat until the next plunger spring placement slot corresponds to the first feed port, and the push plate pushes the next plunger spring into the plunger spring placement slot, and so on, until all the plunger spring placement slots in the first rotating seat are filled. S3.4, the gripping mechanism moves multiple plunger springs simultaneously into the plunger seat to be assembled, and the clamping and positioning mechanism continues to move along the guide rail.

[0157] Based on the above technical solution, the step S3.1 of distributing the plunger springs includes the following steps: S3.11, Multiple plunger springs enter the first material distribution channel from the first vibrating plate through the first conveying pipe; S3.12, the first cylinder extends to block all the plunger springs falling in the first material distribution channel; S3.13, when the plunger spring falls to contact the extended first cylinder, the second cylinder extends, the free height of the plunger spring is Hf, the range of the height H between the first cylinder and the second cylinder is Hf < H < 2Hf, when the second cylinder extends, it presses down the second plunger spring counted from bottom to top. S3.14, the first cylinder retracts, and the first piston spring counted from bottom to top, which is also the lowest, falls to the bottom of the first material distribution seat; S3.15, the push plate moves in the direction close to the discharge port, pushes the plunger spring out of the discharge port, pushes it into the corresponding plunger spring placement slot through the first feed port, the push plate retracts, and proceeds to step S3.12 to continue distributing materials.

[0158] Furthermore, in step 3.3, the first rotating seat rotates relative to the first fixed seat until the next plunger spring placement slot corresponds to the first feed port. After rotation, the second sensor corresponds to the plunger spring placement slot that has just been placed. The second sensor detects whether there is a spring in the plunger spring placement slot. If a spring is detected in the plunger spring placement slot, the next material distribution continues. If no spring is detected, the second sensor sends a signal to control the material distribution component to perform the material distribution operation again, ensuring that the plunger spring can be accurately placed in each plunger spring placement slot, further improving the reliability and accuracy of the entire feeding process.

[0159] Further, in step S6, if it is determined that the plunger pump is missing a gasket 543, the plunger pump is transferred to the scrap bin. A scrap channel is provided below the plunger seat feeding mechanism 1, and the scrap channel is connected to the scrap bin. After the clamping and positioning mechanism 15 passes the detection of the plunger pump gasket detection mechanism 5, it continues to move along the guide rail 71 to the corresponding position of the plunger seat feeding mechanism 1. The first transfer mechanism 12 moves the plunger pump with missing gasket 543 to the scrap channel below, and the plunger pump slides down the scrap channel into the scrap bin. If it is determined that the plunger pump is not missing a gasket 543, the first transfer mechanism 12 moves the plunger pump that has completed assembly and passed inspection back to the original position of the storage tray 11.

[0160] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
