For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] Combine the following Figure 1-Figure 13 A specific embodiment of the pump head assembly assembly system of the present invention is described.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a pump head assembly system, including: a workstation bracket 100, which encloses an assembly work area; a truss 110, which is arranged above the workstation bracket 100 and connected to the workstation bracket 100 through a moving mechanism, so that the truss 110 can move laterally above the assembly work area; a pump head slide 120, which extends through the inside and outside of the assembly work area and is used for loading and unloading the pump head body 101; an accessory slide 130, which extends through the inside and outside of the assembly work area and is used for loading and unloading the pump head accessories; a mechanical arm 140, which is located in the middle of the assembly work area and is used for grasping and assembling the pump head accessories; a positioner 150, which is arranged on one side of the mechanical arm 140, includes a bearing platform 151, which can be deflected relative to the horizontal plane, and is used to carry the pump head body 101 and adjust its posture; a grasping mechanism 160, which is arranged on the truss 110, and is used to grasp the pump head body 101; a tightening mechanism 170, which is arranged on the truss 110, and is used to tighten the assembly bolts. The pump head assembly system achieves efficient, safe and high-quality automated assembly through multiple key components and technical means.

[0035] First, the workstation support 100 encloses the assembly work area, providing a closed operating environment for the entire assembly process, ensuring the safety and orderliness of the operation. Second, the truss 110 is arranged above the workstation support 100 and connected to the workstation support 100 through a moving mechanism, so that the truss 110 can move horizontally above the assembly work area.

[0036] like Fig.11 and Fig.12 As shown, the pump head slide 120 and the accessory slide 130 extend through the inside and outside of the assembly work area respectively, and are used for loading and unloading the pump head body 101 and accessories, making the material loading and unloading more convenient, reducing manual intervention, and improving the degree of automation. The mechanical arm 140 is located in the middle of the assembly work area and is used for grabbing and assembling the pump head accessories. The mechanical arm 140 replaces the traditional manual operation and improves the assembly speed and accuracy.

[0037] like Fig.13 As shown, the positioner 150 is arranged on one side of the robot arm 140, including a bearing platform 151, which can be deflected relative to the horizontal plane, for carrying the pump head body 101 and adjusting its posture, so that the pump head body 101 can be automatically adjusted to the best posture during the assembly process, thereby ensuring the accuracy and consistency of the assembly. The grasping mechanism 160 is arranged on the truss 110, for grasping the pump head body 101. Through automated grasping, the safety hazards caused by manual handling are avoided, and the accuracy and efficiency of grasping are improved. In use, the pump head body 101 grasped by the truss 110 is transported to the top of the positioner 150, and the positioner 150 adjusts the posture of the bearing platform 151 to a horizontal position in advance, so as to pick up the pump head body 101 from the truss 110, and then the positioner 150 picks up the pump head body 101 and the pump head tooling plate 121 together and automatically fixes them, and then the positioner 150 starts to flip (rotate) and switch to the assembly posture. Preferably, the positioner 150 has a maximum load-bearing capacity of 2000 kg.

[0038] The tightening mechanism 170 is arranged on the truss 110 and is used to tighten the assembly bolts, thereby ensuring the consistency and reliability of the bolt tightening and avoiding quality problems that may be caused by manual operation. It is understandable that integrating the tightening mechanism 170 on the truss 110 can offset the reverse torque during tightening. When the assembly step of bolt tightening is carried out, the robot arm 140 grabs the bolt from the accessory slide 130 and places it in the threaded hole. After that, the truss 110 together with the tightening mechanism 170 runs again to the top of the pump head to tighten the bolt. Among them, the tightening mechanism 170 can preferably automatically switch the tightening head according to different bolt specifications. At the same time, the tightening mechanism 170 preferably also has a data recording function. Through the integrated torque sensor, the bolt tightening torque at each position can be recorded.

[0039] Through the collaborative work of the above components, the pump head assembly system of the present invention achieves the following improvements: in terms of efficiency, the assembly efficiency is significantly improved through functions such as automated loading and unloading, gripping and assembly by the robot arm 140, and automatic posture adjustment; in terms of safety, automated operation reduces manual intervention and reduces the safety risk of operators; in terms of high quality, through precise positioning, posture adjustment and tightening mechanism 170, the consistency and reliability of assembly are ensured, and the overall assembly quality is improved. During the assembly process, the operator only needs to start and stop the system on the operating table. At the same time, the system is preferably equipped with isolation protection devices around it, such as an isolation net set between the workstation brackets 100, to ensure the safety of the operator.

[0040] When the assembly system completes all the assembly steps of the pump head, the truss 110 grabs the pump head body 101 from the positioner 150, and then transports and places it on the pump head slide 120, and then the pump head slide 120 is transported to the outside of the assembly system to complete the entire assembly process. Preferably, the above-mentioned pump head slide 120 and accessory slide 130 can be provided with two each. Figure 1 As shown, the two pump head slides 120 operate alternately to simultaneously deliver the pump head body 101 to be assembled into the workstation and deliver the assembled pump head body 101 out of the workstation; similarly, the two accessory slides 130 operate alternately to respectively deliver and deliver the pump head accessories.

[0041] According to a pump head assembly system of the present invention, the moving mechanism includes a first driving component, a first slide rail 111 and a first slide 112; the first slide 112 is arranged at both ends of the truss 110, and the first slide rail 111 is arranged on two top beams on opposite sides of the workstation bracket 100, and the first driving component is used to drive the first slide 112 to move laterally along the first slide rail 111. The first slide 112 is arranged at both ends of the truss 110, and is used to support the truss 110 and enable it to move laterally above the assembly work area. The first slide 112 is driven by the first driving component to move along the first slide rail 111 to achieve lateral movement of the truss 110.

[0042] According to a pump head assembly system of the present invention, the first slide rail 111 is provided with a rack structure; the first drive assembly includes a servo motor arranged on the first slide 112 and a driving gear connected to the servo motor, and the driving gear is meshed with the rack structure. The servo motor is meshed with the rack structure on the first slide rail 111 through the driving gear, and drives the first slide 112 to move laterally along the first slide rail 111. The movement of the first slide 112 drives the truss 110 to move laterally above the assembly work area, so as to realize the precise positioning of the pump head body 101 and accessories. The use of the servo motor ensures the precise movement of the first slide 112, and improves the accuracy and reliability of the assembly process. The cooperation of the rack structure and the driving gear enables the truss 110 to move laterally stably above the assembly work area, ensuring the smooth progress of the assembly process.

[0043] In actual applications, the precise control of the moving mechanism enables the truss 110 to move quickly and accurately above the assembly work area. For example, when the pump head body 101 needs to be moved from the pump head slide 120 to above the positioner 150, the servo motor drives the first slide 112 along the first slide rail 111 through the driving gear to accurately move the pump head body 101 to the predetermined position. Similarly, when the assembled pump head body 101 needs to be moved from the positioner 150 to the pump head slide 120, the moving mechanism also plays a role to ensure the precise movement of the pump head body 101.

[0044] like Figure 4 As shown, according to a pump head assembly assembly system of the present invention, a second slide rail 113 is provided on the truss 110, a second slide 114 and a second drive assembly are provided on the second slide rail 113, and the second drive assembly is used to drive the second slide 114 to move along the second slide rail 113; the grabbing mechanism 160 and the tightening mechanism 170 are both provided on the second slide 114. By providing the second slide rail 113 on the truss 110, the grabbing mechanism 160 and the tightening mechanism 170 are precisely positioned in the assembly work area. In use, the second drive assembly drives the second slide 114 to move along the second slide rail 113, so that the grabbing mechanism 160 and the tightening mechanism 170 can accurately reach the desired position.

[0045] Specifically, the second slide rail 113 is arranged on the truss 110, providing a moving track for the second slide 114. The second drive assembly (usually including a servo drive and a transmission structure) drives the second slide 114 to move along the second slide rail 113. The grabbing mechanism 160 and the tightening mechanism 170 are both arranged on the second slide 114, and accurate positioning and operation are achieved through the movement of the second slide 114. In actual use, the second drive assembly drives the second slide 114 to move along the second slide rail 113 to ensure that the grabbing mechanism 160 can accurately grab the pump head body 101 and move the pump head body 101 to the specified position. At the same time, the tightening mechanism 170 can also accurately reach the position of the bolt for tightening operation through the movement of the second slide 114.

[0046] like Figure 4 and Figure 5 As shown, according to a pump head assembly system of the present invention, the grasping mechanism 160 includes a vertical movable frame 161 arranged on the second slide 114, and a clamping portion 162 arranged at the bottom end of the vertical movable frame 161; the tightening mechanism 170 includes a mounting plate 171 arranged on one side of the clamping portion 162, a driving cylinder 172 arranged on the mounting plate 171, and a sliding seat 173 slidably arranged on the mounting plate 171 in the vertical direction, and a tightener 174 facing downward is arranged on the sliding seat 173. By arranging the vertical movable frame 161 and the clamping portion 162 on the second slide 114, accurate grasping and positioning of the pump head body 101 is achieved. Specifically, the vertical movable frame 161 drives the clamping portion 162 to move up and down, ensuring that the clamping portion 162 can accurately grasp the pump head body 101. At the same time, the tightening mechanism 170 realizes the precise movement of the tightener 174 in the vertical direction through the design of the mounting plate 171, the driving cylinder 172 and the sliding seat 173. In actual use, the second slide 114 drives the vertical moving frame 161 and the clamping part 162 to move to the position of the pump head body 101, and the clamping part 162 grabs the pump head body 101; the tightening mechanism 170 drives the sliding seat 173 to move up and down through the driving cylinder 172, so that the tightener 174 can accurately tighten the bolt.

[0047] According to the above embodiment, a three-axis regional motion mechanism is formed based on the truss 110, which realizes the movement of the grabbing mechanism 160 and the tightening mechanism 170 in various horizontal directions and vertical height. Each part of the mechanism is preferably driven by a servo motor and adopts a gear rack transmission method, with a maximum load-bearing capacity of 2000Kg, which can meet the assembly requirements of pump heads of all specifications, and the repeat positioning accuracy is within ±1mm.

[0048] like Figure 6As shown, according to a pump head assembly assembly system of the present invention, the pump head slide 120 is provided with a pump head tooling plate 121, and the pump head tooling plate 121 is provided with a positioning piece 122 adapted to the bottom edge shape of the pump head body 101, thereby realizing the precise positioning and stable support of the pump head body 101. Specifically, in the process of the pump head slide 120 sending the pump head body 101 from the outside into the assembly work area, the positioning piece 122 on the pump head tooling plate 121 ensures the precise position of the pump head body 101 on the tooling plate. In this way, the pump head body 101 can be accurately positioned and stably supported throughout the entire assembly process, thereby ensuring the efficiency and quality of the assembly process. In actual use, the pump head slide 120 sends the pump head body 101 into the assembly work area, and the positioning piece 122 on the pump head tooling plate 121 ensures the precise positioning of the pump head body 101, thereby ensuring the smooth progress of the assembly process.

[0049] According to a pump head assembly system of the present invention, each pump head tooling plate 121 is configured with four positioning members 122; the positioning members 122 are respectively provided with positioning grooves adapted to the shapes of the four bottom corners of the pump head body 101. By configuring four positioning members 122 on the pump head tooling plate 121, and providing positioning grooves adapted to the shapes of the four bottom corners of the pump head body 101 on the positioning members 122, accurate positioning and stable support of the pump head body 101 are achieved. Specifically, each pump head tooling plate 121 has four positioning members 122, and each positioning member 122 is provided with positioning grooves adapted to the shapes of the four bottom corners of the pump head body 101. In this way, when the pump head body 101 is placed on the pump head tooling plate 121, the four bottom corners can be accurately embedded in the positioning grooves, ensuring that the position of the pump head body 101 during the assembly process is accurate and stable. When the pump head body 101 is placed on the pump head tooling plate 121 , the four bottom corners are precisely matched with the positioning members 122 through the positioning grooves, thereby ensuring that the position of the pump head body 101 is stable and reliable during the entire assembly process.

[0050] According to a pump head assembly system of the present invention, for each positioning member 122, the pump head tooling plate 121 is respectively provided with a plurality of mounting positions adapted to the positioning member 122; when the positioning member 122 is arranged at different mounting positions, positioning structures for compatibility with pump head bodies 101 of different models or specifications are respectively formed between the positioning members 122. The position of the positioning member 122 is adjusted according to the pump head bodies 101 of different models or specifications, so as to achieve accurate positioning and compatibility of the pump head bodies 101. Specifically, a plurality of mounting positions are provided for each positioning member 122 on the pump head tooling plate 121. According to the different models or specifications of the pump head bodies 101, the positioning member 122 can be placed at different mounting positions, so as to form different positioning structures between the positioning members 122. In this way, pump head bodies 101 of different models or specifications can be accurately positioned and firmly supported on the pump head tooling plate 121 by adjusting the position of the positioning member 122. Therefore, the pump head tooling plate 121 is compatible with pump head bodies 101 of various specifications, and it is only necessary to adjust the positioning member 122 to the corresponding position according to the mark.

[0051] like Figure 7 , Figure 8 and Fig. 9 As shown, according to a pump head assembly system of the present invention, a gripper library 180 is provided on one side of a robot arm 140, and the gripper library 180 is provided with a plurality of storage stations for storing gripper workpieces 141 of different shapes, and the gripper workpieces 141 of different shapes correspond to different types of pump head accessories. By providing the gripper library 180 on one side of the robot arm 140 and providing a plurality of storage stations in the gripper library 180, automatic replacement of gripper workpieces 141 of different shapes is achieved, so that different types of pump head accessories can be grasped.

[0052] Specifically, the robot arm 140 needs to grab different types of pump head accessories during the assembly process. The gripper library 180 is set on one side of the robot arm 140, which includes multiple storage stations for storing gripper workpieces 141 of different shapes. These gripper workpieces 141 are automatically replaced as needed to ensure that the robot arm 140 can accurately grab various types of pump head accessories. The robot arm 140 can adapt to different types of pump head accessories by automatically replacing the gripper workpieces 141 in the gripper library 180, thereby achieving an efficient and accurate assembly process.

[0053] According to the above embodiment, when the positioner 150 switches to the assembly posture and the accessory slide 130 has completed the delivery of the accessory, the robot arm 140 starts to grab the accessory and assemble it into the pump head body 101. A gripper library 180 is configured next to the robot arm 140, and the gripper workpiece 141 is automatically switched according to the accessories of different shapes. The gripper workpiece 141 or the end of the robot arm 140 is preferably equipped with a displacement sensor, which can accurately measure the position after assembly to ensure the assembly quality.

[0054] like Fig.10 As shown, according to a pump head assembly assembly system of the present invention, the accessory slide 130 is provided with an accessory tooling plate 131, and the accessory tooling plate 131 is provided with a plurality of storage areas for storing different types of accessories; different types of pump head accessories are placed correspondingly on the accessory tooling plate 131 according to their corresponding storage areas. By setting the accessory tooling plate 131 on the accessory slide 130 and setting a plurality of storage areas on the accessory tooling plate 131, classified storage and precise management of different types of pump head accessories are achieved. Specifically, the accessory slide 130 delivers the pump head accessories into the assembly work area, and the plurality of storage areas on the accessory tooling plate 131 ensure that different types of pump head accessories can be stored in a classified manner. Different types of pump head accessories are placed correspondingly on the accessory tooling plate 131 according to their corresponding storage areas, thereby achieving orderly management and precise grasping. In actual use, the storage area on the accessory tooling plate 131 ensures that different types of pump head accessories can be stored in order, and the robot arm 140 can grab the required accessories from the corresponding storage area as needed, thereby ensuring the efficiency and accuracy of the assembly process. The storage area is preferably designed with dedicated card slots according to the shapes of different accessories to ensure the uniqueness and directionality of the placement of the accessories. After the accessories are placed, they are transported to the inside of the assembly system by the accessory slide 130 for easy assembly.
