[0034] The specific embodiments of the pump head assembly assembly system of the application are described below. Figures 1-13 The specific embodiments of the pump head assembly assembly system of the application are described below.

[0035] As shown in Figure 1 , Figure 2 and Figure 3 , the application provides a pump head assembly assembly system, comprising: a workstation support 100 surrounding an assembly work area; a truss 110 arranged above the workstation support 100 and connected to the workstation support 100 through a moving mechanism, so that the truss 110 can move transversely above the assembly work area; a pump head sliding table 120 extending through the inside and outside of the assembly work area, used for feeding and discharging the pump head body 101; a fitting sliding table 130 extending through the inside and outside of the assembly work area, used for feeding and discharging the pump head fitting; a mechanical arm 140 located in the middle of the assembly work area, used for grabbing and assembling the pump head fitting; a positioner 150 arranged on one side of the mechanical arm 140, comprising a carrying table 151 capable of deflecting relative to the horizontal plane, used for carrying the pump head body 101 and adjusting its posture; a grabbing mechanism 160 arranged on the truss 110, used for grabbing the pump head body 101; a tightening mechanism 170 arranged on the truss 110, used for fastening the assembly bolts. The pump head assembly assembly system realizes efficient, safe and high-quality automatic assembly through a plurality of key components and technical means.

[0036] Firstly, the workstation support 100 surrounds the assembly work area, providing a closed operating environment for the entire assembly process, ensuring the safety and orderliness of the operation. Secondly, 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 transversely above the assembly work area.

[0037] As shown in Figure 11 and Figure 12 , the pump head sliding table 120 and the accessory sliding table 130 extend through the assembly work area respectively, for feeding and discharging the pump head body 101 and the accessories, so that the material is more convenient to enter and exit, reduces manual intervention, and improves the degree of automation. The mechanical arm 140 is located in the middle of the assembly work area, for grabbing and assembling the pump head accessories. The mechanical arm 140 replaces the traditional manual operation, improves the assembly speed and accuracy.

[0038] As shown in Figure 13 , the positioner 150 is arranged on one side of the mechanical arm 140, including a carrying table 151 capable of deflecting 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 assembly, thereby ensuring the accuracy and consistency of assembly. The grabbing mechanism 160 is arranged on the truss 110, for grabbing the pump head body 101. Through automatic grabbing, safety hazards caused by manual handling are avoided, and the accuracy and efficiency of grabbing are improved. In use, the truss 110 grabs the pump head body 101 and transports it to the positioner 150 above, the positioner 150 adjusts the posture of the carrying table 151 to a horizontal position in advance, so as to facilitate the pump head body 101 from the truss 110, and then the positioner 150 takes the pump head body 101 and the pump head tool plate 121 together and automatically fixes them, and then the positioner 150 starts to overturn (rotate) and switches to the assembly posture. Preferably, the maximum load of the positioner 150 is 2000Kg.

[0039] The tightening mechanism 170 is arranged on the truss 110, for tightening the assembled bolts, ensuring the consistency and reliability of the bolt tightening, and avoiding quality problems that may be caused by manual operation. It can be understood that the integration of the tightening mechanism 170 on the truss 110 can offset the reverse torque when tightening. When the assembly step of tightening the bolts is performed, the mechanical arm 140 grabs the bolts from the accessory sliding table 130 and places them into the threaded holes, and then the truss 110 together with the tightening mechanism 170 runs above the pump head to tighten the bolts. Among them, according to different bolt specifications, the tightening mechanism 170 is preferably capable of automatically switching the tightening head, and the tightening mechanism 170 is preferably also provided with a data recording function, which can record the bolt tightening torque at each position through the integrated torque sensor.

[0040] Through the cooperation of the above components, the pump head assembly system of the present application realizes the following improvements: in terms of efficiency, through automatic feeding and discharging, mechanical arm 140 grabbing and assembling, automatic posture adjustment and other functions, the assembly efficiency is significantly improved; in terms of safety, automatic operation reduces human intervention and reduces the safety risk of operators; in terms of 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 operate the start and stop of the system on the operation table, and at the same time, the system is surrounded by isolation protection devices, such as the isolation net arranged between the workstation supports 100, which can ensure the safety of the operator.

[0041] When the assembly system completes all assembly steps of the pump head, the truss 110 grabs the pump head body 101 from the positioner 150, then transports and places it on the pump head sliding table 120, and then transports it to the outside of the assembly system by the pump head sliding table 120, completing the entire assembly process. Preferably, the above pump head sliding table 120 and the accessory sliding table 130 can be provided with two respectively. As shown in Figure 1 , two pump head sliding tables 120 operate alternately to simultaneously send the pump head body 101 to be assembled into the workstation and send the assembled pump head body 101 out of the workstation; similarly, two accessory sliding tables 130 operate alternately to send the pump head accessories in and out respectively.

[0042] According to the pump head assembly system of the present application, the moving mechanism includes a first driving assembly, a first sliding rail 111 and a first sliding table 112; the first sliding table 112 is arranged at both ends of the truss 110, the first sliding rail 111 is arranged on the two top cross beams on the opposite sides of the workstation support 100, and the first driving assembly is used to drive the first sliding table 112 to move laterally along the first sliding rail 111. The first sliding table 112 is arranged at both ends of the truss 110, used to support the truss 110 and enable it to move laterally above the assembly work area. The first sliding table 112 moves along the first sliding rail 111 through the driving of the first driving assembly, realizing the lateral movement of the truss 110.

[0043] According to the pump head assembly assembling system, the first sliding rail 111 is provided with a rack structure; the first driving assembly includes a servo motor arranged on the first sliding table 112 and a driving gear connected to the servo motor, and the driving gear is engaged with the rack structure. Wherein, the servo motor is engaged with the rack structure on the first sliding rail 111 through the driving gear, and drives the first sliding table 112 to move transversely along the first sliding rail 111. The movement of the first sliding table 112 drives the truss 110 to move transversely above the assembling work area, and realizes the accurate positioning of the pump head main body 101 and the accessories. The use of the servo motor ensures the accurate movement of the first sliding table 112, and improves the accuracy and reliability of the assembling process. The cooperation of the rack structure and the driving gear enables the truss 110 to move stably transversely above the assembling work area, and ensures the smooth progress of the assembling process.

[0044] In actual application, the accurate control of the moving mechanism enables the truss 110 to move quickly and accurately above the assembling work area. For example, when the pump head main body 101 needs to be moved from the pump head sliding table 120 to above the positioner 150, the servo motor drives the first sliding table 112 to move along the first sliding rail 111 through the driving gear, and accurately moves the pump head main body 101 to the predetermined position. Similarly, when the assembled pump head main body 101 needs to be moved from the positioner 150 to the pump head sliding table 120, the moving mechanism also plays a role, and ensures the accurate movement of the pump head main body 101.

[0045] As shown in Figure 4 According to the pump head assembly assembling system, the truss 110 is provided with a second sliding rail 113, the second sliding rail 113 is provided with a second sliding table 114 and a second driving assembly, the second driving assembly is used for driving the second sliding table 114 to move along the second sliding rail 113; the grabbing mechanism 160 and the tightening mechanism 170 are arranged on the second sliding table 114. By arranging the second sliding rail 113 on the truss 110, the accurate positioning of the grabbing mechanism 160 and the tightening mechanism 170 in the assembling work area is realized. In use, the second driving assembly drives the second sliding table 114 to move along the second sliding rail 113, so that the grabbing mechanism 160 and the tightening mechanism 170 can accurately reach the required position.

[0046] Specifically, the second slide rail 113 is arranged on the truss 110 to provide a moving track for the second slide table 114. A second driving assembly (generally comprising a servo driver and a transmission structure) drives the second slide table 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 table 114, and through the movement of the second slide table 114, accurate positioning and operation are realized. In actual use, the second driving assembly drives the second slide table 114 to move along the second slide rail 113, ensuring that the grabbing mechanism 160 can accurately grab the pump head body 101 and move the pump head body 101 to a designated position. At the same time, the tightening mechanism 170 can also accurately reach the position of the bolt for fastening operation through the movement of the second slide table 114.

[0047] As shown in Figure 4 and Figure 5 , according to the pump head assembly system of the present application, the grabbing mechanism 160 comprises a vertical moving frame 161 arranged on the second slide table 114, and a clamping portion 162 arranged at the bottom end of the vertical moving frame 161; the tightening mechanism 170 comprises 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 arranged in the vertical direction on the mounting plate 171, and a tightening device 174 arranged on the sliding seat 173 and facing downward. By arranging the vertical moving frame 161 and the clamping portion 162 on the second slide table 114, accurate grabbing and positioning of the pump head body 101 are realized. Specifically, the vertical moving frame 161 drives the clamping portion 162 to move up and down, ensuring that the clamping portion 162 can accurately grab the pump head body 101. At the same time, the tightening mechanism 170 realizes the accurate movement of the tightening device 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 table 114 drives the vertical moving frame 161 and the clamping portion 162 to move to the position of the pump head body 101, and the clamping portion 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 tightening device 174 can accurately tighten the bolt.

[0048] According to the above-mentioned embodiments, a three-axis area type motion mechanism is formed based on the truss 110, realizing the movement of the grabbing mechanism 160 and the tightening mechanism 170 in horizontal directions and in vertical height. The parts of the mechanism are preferably driven by servo motors and adopt gear and rack transmission mode, with a maximum load of 2000Kg, which can meet the assembly requirements of pump heads of all specifications, and the repeated positioning accuracy is within ±1mm.

[0049] As shown in Figure 6As shown, according to the pump head assembly assembling system of the present application, the pump head sliding table 120 is provided with a pump head tooling plate 121, and the pump head tooling plate 121 is provided with a positioning piece 122 which is adapted to the shape of the bottom edge of the pump head main body 101, so as to realize accurate positioning and stable support of the pump head main body 101. Specifically, during the process that the pump head sliding table 120 sends the pump head main body 101 into the assembling working area from the outside, the positioning piece 122 on the pump head tooling plate 121 ensures the accurate position of the pump head main body 101 on the tooling plate. In this way, the pump head main body 101 can be accurately positioned and stably supported during the whole assembling process, so as to ensure the efficiency and quality of the assembling process. In actual use, the pump head sliding table 120 sends the pump head main body 101 into the assembling working area, and the positioning piece 122 on the pump head tooling plate 121 ensures the accurate positioning of the pump head main body 101, so as to ensure the smooth progress of the assembling process.

[0050] According to the pump head assembly assembling system of the present application, each pump head tooling plate 121 is provided with four positioning pieces 122, and the positioning piece 122 is respectively provided with a positioning groove which is adapted to the shape of the four bottom corners of the pump head main body 101. By configuring four positioning pieces 122 on the pump head tooling plate 121 and setting the positioning grooves which are adapted to the shape of the four bottom corners of the pump head main body 101 on the positioning pieces 122, the accurate positioning and stable support of the pump head main body 101 are realized. Specifically, each pump head tooling plate 121 is provided with four positioning pieces 122, and each positioning piece 122 is provided with a positioning groove which is adapted to the shape of the four bottom corners of the pump head main body 101. In this way, when the pump head main body 101 is placed on the pump head tooling plate 121, the four bottom corners can be accurately embedded in the positioning grooves, so as to ensure the accurate position and stability of the pump head main body 101 during the assembling process. When the pump head main body 101 is placed on the pump head tooling plate 121, the four bottom corners are accurately matched with the positioning pieces 122 through the positioning grooves, so as to ensure the position stability and reliability of the pump head main body 101 during the whole assembling process.

[0051] According to the pump head assembly system, for each positioning piece 122, the pump head tooling plate 121 is respectively provided with a plurality of mounting positions matched with the positioning piece 122; when the positioning pieces 122 are arranged on different mounting positions, a positioning structure for accommodating pump head bodies 101 of different models or specifications is formed between the positioning pieces 122. The positions of the positioning pieces 122 are adjusted according to the pump head bodies 101 of different models or specifications, so that accurate positioning and compatibility of the pump head body 101 are realized. Specifically, the pump head tooling plate 121 is provided with a plurality of mounting positions for each positioning piece 122. According to different models or specifications of the pump head body 101, the positioning pieces 122 can be placed on different mounting positions, so that different positioning structures are formed between the positioning pieces 122. In this way, the pump head body 101 of different models or specifications can be accurately positioned and stably supported on the pump head tooling plate 121 by adjusting the positions of the positioning pieces 122. Therefore, the pump head tooling plate 121 can accommodate pump head bodies 101 of multiple specifications, and the positioning pieces 122 only need to be adjusted to the corresponding positions according to the marks.

By arranging the gripper library 180 on one side of the mechanical arm 140 and arranging a plurality of storage stations in the gripper library 180, automatic replacement of different shapes of gripper workpieces 141 is realized, so that different types of pump head accessories can be gripped.

[0053] Specifically, the mechanical arm 140 needs to grip different types of pump head accessories during assembly. The gripper library 180 is arranged on one side of the mechanical arm 140 and contains a plurality of storage stations for storing different shapes of gripper workpieces 141.

The mechanical arm 140 can adapt to different types of pump head accessories by automatically replacing the gripper workpieces 141 in the gripper library 180, thereby realizing an efficient and accurate assembly process.

[0054] According to the above embodiment, when the positioner 150 is switched to the assembly posture and the accessory sliding table 130 has completed the delivery of the accessory, the mechanical arm 140 starts to grip the accessory and assemble it into the pump head body 101. The gripper library 180 is arranged beside the mechanical arm 140, and the gripper workpieces 141 are automatically switched according to different shapes of accessories. The gripper workpieces 141 or the end of the mechanical arm 140 are preferably equipped with displacement sensors, which can accurately measure the position after assembly to ensure the assembly quality.
