[0064] Based on the problems, the present invention particularly provides a technical solution to the above problems. The technical solution, working principle and technical effects of the present invention are described in detail below in conjunction with specific embodiments.

[0065] Embodiment 1:

[0066] Reference Figure 1 , Figure 2 , Figure 3 As shown, the present invention records a multifunctional assembly machine, aiming to provide an efficient, flexible and automated product assembly equipment, which is particularly suitable for the assembly of various types of products, such as protective caps and stopcocks.

[0067] The assembly machine integrates a rotating mechanism, an assembly mechanism, a discharging mechanism and a controller to achieve full automation of the product from placement, positioning, assembly to discharging, significantly improving production efficiency and product quality.

[0068] This embodiment provides a multifunctional assembly machine, the structure of which is as follows: Figure 1 As shown, it mainly includes four parts: rotating mechanism, assembling mechanism, discharging mechanism and controller.

[0069] The rotating mechanism includes a rotating platform 1 and a turntable 2. The rotating platform 1 drives the turntable 2 to rotate through a motor. A plurality of positioning holes 3 are arranged on the upper part of the turntable 2. These positioning holes 3 are distributed in a circular array on the upper part of the turntable 2 for placing the products to be assembled.

[0070] The assembly mechanism is arranged above the turntable 2 , and includes a cylinder assembly 4 and an assembly tool 5 .

[0071] The cylinder assembly 4 is fixedly connected to the assembly tool 5, and the assembly tool 5 is driven by the telescopic movement of the cylinder to position and assemble the product. The assembly tool 5 includes a connecting block 6 and a punching assembly 7, and the punching assembly 7 is installed on the connecting block 6.

[0072] The punching assembly 7 further comprises a positioning column 8, an ejector pin 9 and an elastic member 10. In this embodiment, the elastic member is preferably a helical spring.

[0073] The positioning column 8 is arranged as a guide sleeve structure, and the ejector pin 9 and the elastic member 10 are arranged inside the guide sleeve structure.

[0074] One end of the ejector pin 9 is fixed, and the elastic member 10 is sleeved on the ejector pin 9 . One end of the elastic member is fixed, and the other end extends out of the free end of the ejector pin 9 .

[0075] During the assembly process, the positioning column 8 is used to position the product to be assembled in the center position, the ejector pin 9 is used to press the product to be assembled to the set position, and the elastic member 10 supports the product during and after assembly to ensure the stability of the product during the assembly process.

[0076] As an optimized design, in order to meet the use requirements of the products to be assembled, a detachable structure is set between the assembly tooling and the discharging mechanism and the turntable. The assembly tooling and the discharging mechanism can be removed from the turntable and replaced with different assembly tooling and discharging mechanisms to adapt to different products to be assembled.

[0077] The discharging mechanism is arranged on one side of the turntable 2 , and includes a blowing device 11 and a transmission channel 12 .

[0078] The installation position and angle of the blowing device can be adjusted to meet the discharging requirements of different products. The blowing device 11 is used to blow the assembled products out from the turntable 2, and the transmission channel 12 transports the products to the material box 13.

[0079] The controller 14 is configured as a programmable logic controller (PLC), which is electrically connected to the rotating table 1, the assembly mechanism, and the discharging mechanism, and is used to control the entire assembly process, including the rotation of the rotating table 1, the assembly action of the assembly mechanism, and the unloading action of the discharging mechanism.

[0080] The multifunctional assembly machine can be used to assemble protective caps and plug valves.

[0081] Among them, a connecting part is arranged at the lower part of the protective cap to be assembled, and the protective cap is matched with the positioning hole on the turntable through the connecting part. During assembly, the protective cap is inserted into the positioning hole on the turntable through the connecting part.

[0082] like Figure 4 , Figure 5 , Figure 6As shown, for the plug valve to be assembled, a mounting seat is provided at the position on the turntable corresponding to the position of the plug valve to be assembled, and the mounting seat is provided in plurality, and the mounting seats are respectively installed on the positioning holes provided on the turntable, and one mounting seat is installed corresponding to each positioning hole. A groove is provided on the mounting seat, and the shape of the groove matches the shape of the plug valve.

[0083] In order to facilitate material discharge, a hole is opened at the bottom of the groove, and the blowing device blows the assembled plug valve out of the groove of the mounting seat through the bottom hole, and enters the material taking box through the discharging mechanism.

[0084] Based on the description of the relevant structural design of the above-mentioned multifunctional assembly machine, the specific working principle of the multifunctional assembly machine of the present invention is as follows:

[0085] 1. Product positioning: The products to be assembled (such as protective caps, plug valves, etc.) are placed in the positioning holes 3 on the turntable 2. The turntable 2 is driven by the motor to rotate the turntable 1, so that each positioning hole 3 can be moved to the assembly station in turn. Among them, the circular array distribution of the positioning holes 3 ensures that each product can enter the assembly process evenly and orderly.

[0086] 2. Assembly preparation:

[0087] When a certain positioning hole 3 carries the product and moves to the assembly station, the controller 14 (programmable logic controller) issues a command to start the assembly mechanism.

[0088] The cylinder assembly 4 starts to work, and its piston rod extends downward, driving the assembly tool 5 to move downward.

[0089] 3. Product positioning and assembly:

[0090] The positioning column 8 in the assembly tool 5 first contacts and stabilizes the product to ensure that the product is in the vertical center position during the assembly process. Then, the ejector pin 9, driven by the cylinder assembly 4, moves downward along the guide sleeve structure of the positioning column 8, pressing the product to the set position to complete the assembly action.

[0091] During and after the assembly process, the elastic member 10 always supports the product, providing necessary support and stability to prevent the product from being displaced or damaged due to external forces.

[0092] 4. Assembly completion and reset:

[0093] After the assembly is completed, the piston rod of the cylinder assembly 4 retracts, driving the assembly tool 5 to reset. The elastic member 10 continues to support the product to maintain the product in a stable state until the next assembly cycle begins.

[0094] 5. Product discharging:

[0095] When the assembled product moves to the discharging station, the controller 14 starts the discharging mechanism. At this time, the blowing device 11 generates airflow to blow the product out of the positioning hole 3 on the turntable 2.

[0096] The product is then transported to the material picking box 13 through the transmission channel 12, completing the entire automated assembly process.

[0097] 6. Cycle operation:

[0098] The controller 14 repeats the above steps according to the preset program and instructions to achieve continuous and efficient automated assembly operations. The multifunctional assembly machine can also adapt to the assembly requirements of products of different shapes and sizes by adjusting program parameters and replacing assembly tools 5, showing strong flexibility and adaptability.

[0099] Embodiment 2: Method for assembling protective caps using a multifunctional assembly machine

[0100] This embodiment provides the use of Figure 1 The specific method of assembling the protective cap by the multifunctional assembly machine shown is as follows:

[0101] 1. Preparation stage:

[0102] The protective cap 15 is accurately placed in the positioning hole 3 of the turntable 2. The lower connecting portion of the protective cap 15 needs to accurately match the shape and size of the positioning hole 3 to ensure that the protective cap can be stably placed during the assembly process without shaking or offsetting.

[0103] The electric rotating table 1 is started by the controller 14, and the movement of the turntable 2 is precisely controlled to smoothly rotate it to the preset assembly station. This process needs to ensure the rotation speed and position accuracy of the turntable 2 so that the subsequent assembly operation can proceed smoothly.

[0104] 2. Assembly stage:

[0105] The cylinder ejector rod of the assembly mechanism starts to move downward under the command of the controller 14. At this time, the positioning column 8 in the assembly tool 5 first contacts the protective cap 15, and stabilizes the protective cap in its vertical center position by means of its guide sleeve structure.

[0106] Next, the ejector pin 9, driven by the cylinder assembly 4, precisely presses the protective cap 15 along the guide path of the positioning column 8 until it reaches the set assembly position. This process requires strict control of the pressing force and speed to avoid damage to the protective cap.

[0107] When the ejector pin 9 is pressed down, the elastic member 10 is gradually compressed to provide additional support for the protective cap. When the assembly action is completed, the elastic member 10 maintains the top pressure on the protective cap to ensure its stability at the assembly station.

[0108] 3. Reset and fixation stage:

[0109] After the assembly is completed, the cylinder ejector rod is slowly pulled back under the control of the controller 14. At this time, due to the elastic force of the elastic member 10, the protective cap 15 is firmly supported on the assembly station, effectively preventing it from being ejected or displaced due to external force.

[0110] After the protective cap is stably fixed, the controller 14 starts the electric rotating platform 1 again to smoothly rotate the assembled protective cap 15 to the unloading station. This process needs to ensure the stability and accuracy of the rotation so that the subsequent unloading operation can proceed smoothly.

[0111] 4. Discharging stage:

[0112] When the protective cap 15 arrives at the discharging station, the blowing device 11 of the discharging mechanism is started under the instruction of the controller 14. A soft and stable airflow is ejected from the blowing device, and the protective cap is gently blown off the turntable 2.

[0113] The blown-off protective cap is then smoothly transported to the material taking box 13 through the transmission channel 12. During the transmission process, it is necessary to ensure that the channel is unobstructed and the protective cap is stably transmitted to avoid it being damaged or lost.

[0114] 5. Cycle operation:

[0115] After completing the above steps, the multifunctional assembly machine enters the next assembly cycle under the precise control of the controller 14. By continuously repeating the above operation process, the assembly machine can achieve efficient and continuous assembly of the protective cap.

[0116] During the entire assembly process, the controller 14 needs to accurately control each component according to preset programs and parameters to ensure the smooth progress of each assembly step and the stable and reliable assembly quality.

[0117] In summary, the multifunctional assembly machine and the protective cap assembly method provided in this embodiment realize efficient and accurate assembly of the protective cap through precise control and stable mechanical structure design. This method not only improves production efficiency, but also ensures the stability and consistency of assembly quality.

[0118] Embodiment 3: Method for assembling a plug valve using a multifunctional assembly machine

[0119] This embodiment provides the use of Figure 4 The specific method of assembling the plug valve using the multifunctional assembly machine shown is as follows:

[0120] Step 1: Preparation for tooling replacement

[0121] First, the assembly tool 5 currently connected to the cylinder assembly 4 needs to be removed safely and securely (this tool was originally used for the protective cap assembly).

[0122] According to the assembly requirements of the plug valve, select and install the appropriate plug valve assembly tool. This step needs to ensure that the connection between the new tool and the cylinder assembly 4 is stable and reliable to avoid any looseness or deviation in subsequent operations.

[0123] Step 2: Precise positioning of the plug valve

[0124] The plug valve 16 to be assembled is gently placed in the groove 171 of the special mounting seat 17 on the upper part of the rotating disk 2. This groove design needs to fit closely with the shape of the plug valve to ensure its stable placement.

[0125] A special positioning block (not shown in the figure but a necessary component) is used to further fix the plug valve 16 to ensure that it remains stationary throughout the entire assembly process to avoid displacement due to external interference.

[0126] Step 3: Automated assembly process

[0127] After receiving the start signal, the controller 14 immediately activates the electric rotating table 1 and drives the turntable 2 to rotate smoothly to the preset assembly station.

[0128] The cylinder ejector rod in the assembly mechanism moves slowly downward under the drive of the control command until it directly presses the valve core of the plug valve 16 to the preset assembly position. In this process, due to the unique structural characteristics of the plug valve 16, no additional positioning column or ejector pin may be required for auxiliary positioning.

[0129] After completing the assembly action, the cylinder ejector rod is automatically pulled back to the initial position under the control of the controller, making full preparations for the next assembly operation.

[0130] Step 4: Finished product output and collection

[0131] The controller 14 starts the electric rotary table 1 again, and smoothly transfers the successfully assembled plug valve 16 to the discharging station.

[0132] The blowing device 11 of the discharging mechanism starts up quickly after receiving the control signal, and generates a strong airflow through the special opening at the bottom of the groove on the mounting seat 17 (although not directly shown in the figure, it has been clearly mentioned in the description of the embodiment), so as to blow the stopcock 16 off the turntable 2.

[0133] The blown-off stopcock 16 then slides smoothly along the carefully designed transmission channel 12 into the material taking box 13 for subsequent quality inspection, packaging or delivery processes.

[0134] In summary, the method for assembling a plug valve using a multifunctional assembly machine provided in this embodiment not only achieves a high degree of automation and intelligence, but also achieves significant improvements in assembly accuracy and efficiency.

[0135] The assembly mechanism and the discharging mechanism of the present invention can be replaced and adjusted according to different uses, thereby realizing multifunctional assembly. Specifically, the assembly mechanism includes a cylinder, a tooling, and electrical components, etc., and these components can be selected and replaced according to actual assembly requirements. By replacing different assembly mechanisms, the present invention can adapt to the assembly requirements of different products, greatly improving the flexibility and adaptability of the production line. At the same time, the discharging mechanism can also be adjusted as needed to ensure that the assembled products can be discharged smoothly and fall into the material collection box.

[0136] In addition, the controller of the present invention adopts a programmable logic controller (PLC), which is electrically connected to the rotating table, the assembly mechanism, and the discharging mechanism. Through programming control, the electric rotating table can be accurately controlled to rotate clockwise or counterclockwise, single or continuous, at any angle. This flexible rotation control method enables the present invention to be accurately adjusted according to the assembly process of different products, thereby further improving production efficiency and product quality.

[0137] Through the implementation of the present invention, the problems of complex structure, single function and high price of traditional assembly machines can be solved, the flexibility and adaptability of the production line can be improved, the production cost can be reduced, and the production efficiency can be improved.

[0138] At the same time, the present invention also has the advantages of simple and stable structure, convenient operation, etc., and is suitable for the automated assembly production of various products.

[0139] In summary, the multifunctional assembly machine of the present invention realizes the full automation of product assembly through highly integrated and automated design, significantly improving production efficiency and product quality. At the same time, its flexible and adjustable structural design enables the equipment to adapt to the assembly requirements of different products, and has broad application prospects and market value.
