Technical Field

[0001] This utility model relates to the field of gasket assembly technology, and in particular to an automatic assembly mechanism for multi-specification gasket groups. Background Technology

[0002] The assembly of multiple gaskets and valve plates is a crucial step in mechanical assembly, and its technical issues directly affect the sealing performance, operating efficiency, and reliability of the equipment. In recent years, with the increasing demand for high-precision assembly in industries such as automotive, hydraulics, and fluid control, related technology research and development has focused on solving the pain points of traditional processes and promoting automation and intelligent upgrades.

[0003] Patent document CN202211210001.X discloses a screw and washer assembly device, which includes a device housing. The device housing is provided with an assembly inlet slide for placing unassembled screws and washers and an assembly outlet slide for discharging assembled screws and washers. A rotary wheel is provided inside the device housing. The rotary wheel is connected to a drive mechanism for driving it to rotate around its axial direction. The assembly inlet slide and the assembly outlet slide are arranged coaxially in the 180° circumferential direction of the rotary wheel. An assembly positioning groove for placing screws and washers is provided on the rotary wheel. The groove includes a screw movement positioning groove opened on the surface of the rotary wheel along the axial direction of the rotary wheel and a rotary washer positioning groove coaxially connected to its middle. A pushing structure is provided inside the device housing for driving the screw to move toward the rotary washer positioning groove and pass through the washer.

[0004] However, in actual use, the inventors found that if the positioning reference is not uniform or the tooling limit fails during the stacking and installation of multiple gaskets and valve plates, it can easily lead to misalignment of the sealing surface, causing problems such as media leakage or pressure loss. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by assembling different gaskets and valve plates on the support platform using a modular assembly, picking them up and limiting their position, and stably outputting them to the assembly assembly and precisely assembling them with the piston rod. This solves the technical problem that if the positioning reference is not uniform or the tooling limit fails during the stacked installation of multiple gaskets and valve plates, misalignment of the sealing surface can easily occur, leading to media leakage or pressure loss.

[0006] To address the above technical problems, the following technical solution is adopted: an automatic assembly mechanism for multi-specification gasket groups, comprising: A support platform, wherein a number of positioning posts are arranged along its linear direction; An assembly assembly, disposed above the support platform, includes a transfer member and a lifting member that moves under the transmission of the transfer member; and An assembly component is disposed at the output end of the assembly component, and includes a switching element and carriers evenly distributed along the circumferential direction of the switching element.

[0007] Preferably, the positioning post includes a support platform that extends outward along the circumferential direction.

[0008] Preferably, the two adjacent positioning posts are staggered in height.

[0009] Preferably, the transfer member includes a truss, a first sliding frame that moves horizontally on the truss, and a second sliding frame that moves vertically on the first sliding frame.

[0010] Preferably, both the first sliding frame and the second sliding frame are driven by a pneumatic unit and are transmitted in a guide rail slider structure.

[0011] Preferably, the lifting member includes a side plate installed at the lower end of the second sliding frame, a first pneumatic gripper installed on the side plate, an elastic unit installed on the side plate and located above the first pneumatic gripper, and a pressing column located below the elastic unit. The gripping end of the first pneumatic gripper has an L-shaped structure and the relatively close side is chamfered.

[0012] Preferably, two sets of lifting members are provided along the length direction of the second sliding frame.

[0013] Preferably, the switching component includes a turntable and a servo drive unit for driving the turntable to rotate.

[0014] Preferably, a feeding component is also provided on one side of the switching component and below the carrier. The feeding component includes a bracket, a third sliding frame that is vertically slidably disposed on the bracket, and a limiting post that is installed on the upper end of the third sliding frame and is matched and inserted into the lower end of the piston rod.

[0015] As another preferred embodiment, the carrier includes a base, a second pneumatic gripper mounted above the base, and a third pneumatic gripper that is horizontally slidably mounted on the base and located above the second pneumatic gripper.

[0016] The beneficial effects of this utility model are: (1) In this utility model, different gaskets and valve plates on the bearing platform are assembled by the assembly component, and they are picked up and limited to avoid the phenomenon of scattering during the transfer process. They are stably output to the assembly component and precisely assembled with the piston rod. The precise assembly of multiple sets of gaskets and valve plates will develop the product assembly in the direction of high precision, high efficiency and long life, providing core support for the safe and stable operation of high-end equipment. (2) In this utility model, by setting the chamfer structure of the first pneumatic gripper, the gasket or valve plate is extracted. During the picking process, the gasket or valve plate moves upward along the chamfer and acts on the lower end of the pressure column. This has enabled stable clamping of any number of stacked gaskets or valve plate groups for different specifications of products, reducing the switching cost of multi-variety small-batch production, and preventing the phenomenon of scattering during the transfer process.

[0017] In summary, this equipment has the advantages of simple structure and stable transfer, and is especially suitable for the field of gasket assembly technology. Attached Figure Description

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example 1 like Figure 1 As shown, an automatic assembly mechanism for multi-specification gasket sets includes: A support platform 1, wherein a plurality of positioning posts 11 are arranged along its linear direction; Assembly component 2, disposed above the support platform 1, includes a transfer member 21 and a lifting member 22 that moves under the transmission of the transfer member 21; and Assembly component 3 is disposed at the output end of assembly component 2, and includes a switching component 31 and carriers 32 evenly distributed along the circumferential direction of the switching component 31.

[0027] In this application, different gaskets and valve plates on the bearing platform 1 are assembled by the assembly component 2, and they are picked up and limited to avoid the phenomenon of scattering during the transfer process. They are stably output to the assembly component 3 and precisely assembled with the piston rod. The precise assembly of multiple sets of gaskets and valve plates promotes the development of product assembly in the direction of high precision, high efficiency and long service life, providing core support for the safe and stable operation of high-end equipment.

[0028] Furthermore, such as Figure 2 As shown, the positioning post 11 includes a support platform 13 that extends outward along the circumferential direction.

[0029] The two adjacent positioning posts 11 are staggered in height.

[0030] It should be noted that by utilizing a special structural design, different gaskets or valve plates are classified and stably placed on the corresponding support platform 13. Furthermore, by using the staggered distribution of positioning columns 11, interference between the lifting component 22 and the positioning column 11 can be avoided when the lifting component 22 descends to pick up materials.

[0031] Furthermore, such as Figure 3 As shown, the transfer member 21 includes a truss 211, a first sliding frame 212 that moves horizontally on the truss 211, and a second sliding frame 213 that moves vertically on the first sliding frame 212.

[0032] Furthermore, both the first sliding frame 212 and the second sliding frame 213 are driven by a pneumatic unit and are transmitted in a guide rail slider structure.

[0033] Furthermore, such as Figure 4-5 As shown, the lifting member 22 includes a side plate 221 installed at the lower end of the second sliding frame 213, a first pneumatic gripper 222 installed on the side plate 221, an elastic unit 223 installed on the side plate 221 and located above the first pneumatic gripper 222, and a pressing column 224 located below the elastic unit 223. The gripping end of the first pneumatic gripper 222 has an L-shaped structure and a chamfer is provided on the relatively close side.

[0034] Two sets of lifting members 22 are provided along the length of the second sliding frame 213.

[0035] It should be noted that the chamfered structure of the first pneumatic gripper 222 is used to extract the gasket or valve plate. During the picking process, the gasket or valve plate moves upward along the bevel of the chamfer and acts on the lower end of the pressure column 224. This allows for stable clamping of any number of stacked gaskets or valve plate groups for different product specifications, reducing the switching cost of multi-variety small-batch production and preventing the phenomenon of scattering during the transfer process.

[0036] Furthermore, such as Figure 6 As shown, the switching component 31 includes a turntable 311 and a servo drive unit 312 that drives the turntable 311 to rotate.

[0037] It should be noted that by setting the switching component 31 as a turntable structure, the piston rod loading station, the valve body loading station, and the unloading station after the valve body and piston rod are assembled are distinguished, each fulfilling its own function and the work is clearly defined.

[0038] Furthermore, the carrier 32 includes a base 321, a second pneumatic gripper 322 mounted on the base 321, and a third pneumatic gripper 323 horizontally slidably mounted on the base 321 and located above the second pneumatic gripper 322.

[0039] In this application, the piston rod is clamped during the transfer process by the second pneumatic gripper 322 of the carrier 32, and the valve body after loading is clamped by the third pneumatic gripper 323. Since the valve body is in an active state at this time, it will scatter during the transfer process, and the positioning is accurate.

[0040] Example 2 like Figure 6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 6 As shown, a loading component 33 is also provided on one side of the switching component 31 and below the carrier 32. The loading component 33 includes a bracket 331, a third sliding frame 332 that is vertically slidably arranged on the bracket 331, and a limiting post 333 that is installed on the upper end of the third sliding frame 332 and is matched and inserted into the lower end of the piston rod 100.

[0041] In this embodiment, by setting the feeding component 33, the piston rod 100 is stably fed into the limiting post 333, so as to ensure that the piston rod is uniquely positioned on the second pneumatic gripper 322. Priority is given to ensuring the positioning accuracy of the piston rod. First, the valve body mounting height is determined, and second, the third pneumatic gripper 323 holds the movable valve body in a precise position. Then, the feeding component 33 is made into a lifting structure to complete vertical feeding and also achieve descent, avoiding transfer interference.

[0042] In detail, the lower end of the piston rod is manually inserted into the limiting post 333. The limiting post 333 is steadily raised to the predetermined position. The second pneumatic gripper 322 clamps the piston rod, and the third sliding frame 332 drives the limiting post 333 to move down and disengage from the piston rod 100. Then the piston rod rotates and transfers.

[0043] Work process: First, assembly component 2 assembles the gasket, valve plate, and valve body together; Then, the piston rod is manually fed to the loading component 33, which sends the piston rod to the second pneumatic gripper 322 of the assembly component 3. Then it rotates to the assembly component 2, which unloads the valve body onto the piston rod at the front end. The third pneumatic gripper 323 holds the valve body and continues to rotate and unload under the traditional condition of the switching component 31, for the transfer assembly of the next product.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0045] Of course, those skilled in the art should understand that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple.
