Description

Technical Field

[0001] This invention relates to the field of diaphragm pump assembly, and particularly to a sealing gasket assembly device for diaphragm pump assembly. Background Technology

[0002] Diaphragm pumps, also known as control pumps, are a major type of actuator. They receive control signals from a regulating control unit and use power to change the fluid flow rate. They are a new type of conveying machinery capable of transporting various corrosive liquids, liquids containing particles, and high-viscosity, volatile, flammable, and highly toxic liquids. Their structural feature lies in the fact that each of the pump's two symmetrical working chambers contains a diaphragm, connected by a central connecting rod. This central connecting rod is a movable rod that pushes the diaphragms through reciprocating motion, thus causing the two diaphragms to reciprocate continuously and synchronously.

[0003] During the assembly of diaphragm pumps, there is a valve chamber cover plate that requires the installation of a sealing gasket. Because the sealing gasket is elastic, it needs to be stretched and installed onto the valve chamber cover plate. This process lacks a mechanized installation mechanism, and the conventional operation is manual installation, which results in low production capacity. Frequent manual repetition of product loading can easily cause worker fatigue, high labor costs, and inconvenience in cooperating with existing automated production lines, leading to low production efficiency in diaphragm pump assembly. Summary of the Invention

[0004] In view of this, the present invention provides a sealing gasket assembly device for diaphragm pump assembly to solve the above-mentioned technical problems.

The downward guide posts pass vertically through the main support plate and have a connecting structure at their free ends on the side of the main support plate away from the support connecting plate for equal-level connection. The main body of the press-fit cylinder is fixed to the main support plate, and its drive end is connected to the support connecting plate. The sealing ring assembly release plate has multiple opening shaft movement holes. The opening shaft movement holes are oblong holes, and their length direction corresponds to the clamping direction of the clamping assemblies. The clamping assemblies include a gripper cylinder mounted on a lifting connecting plate, two opening grippers mounted on the gripper cylinder, and multiple positioning opening shafts mounted on the opening grippers. The spreading grippers are respectively disposed on the two drive ends of the gripper cylinder, and move closer to or further away from each other under the drive of the gripper cylinder. The spreading grippers are located between the support connecting plate and the sealing ring assembly release plate, and are arranged parallel to both. The spreading grippers are provided with multiple support column movement holes. The support column movement holes are oblong holes, and the length direction of the hole is the clamping direction of the clamping assembly. The support connecting column passes through the support column movement holes. The positioning spreading shaft is a columnar optical axis disposed on the spreading grippers, extending towards the side away from the support connecting plate. The positioning spreading shaft passes through the spreading shaft movement hole.

Each support leg includes a fixed base plate, a support pad vertically fixed on the fixed base plate, and a reinforcing rib plate that is perpendicular to both the fixed base plate and the support pad plate. The support pad plate extends upward in a vertical direction perpendicular to the ground.

[0009] Furthermore, the movable slide rail is fixed to the horizontal plate and extends along the length of the horizontal plate. The two movable slide rails are spaced apart from each other and arranged in parallel. The plane on which the movable slide rails are arranged is a vertical plane perpendicular to the ground. The movable sliders are arranged in pairs on the two movable slide rails respectively.

[0010] Furthermore, the lifting mechanism includes a lifting fixed plate disposed on the movable connecting plate, two lifting sliders fixed on the lifting fixed plate, two lifting slide rails disposed on the lifting sliders, a lifting connecting plate disposed on the lifting slide rails, a lifting cylinder fixed on the lifting fixed plate and connected to the lifting connecting plate, and a lifting buffer disposed on the lifting connecting plate.

[0011] Furthermore, the lifting sliders are fixed at intervals and parallel to the lifting fixed plate, and the lifting slide rails are respectively arranged on the lifting sliders, with the extension direction being in a vertical direction perpendicular to the ground.

[0012] Furthermore, six supporting connecting columns are provided, located on both sides of the supporting connecting columns, and the supporting connecting columns on the same side are on the same straight line.

The fixed base plate 111, the support pad 112, and the reinforcing rib 113 are perpendicularly fixed to each other to provide a more stable support structure and ensure the stability of the equipment. The support pad 112 extends upward in a vertical direction perpendicular to the ground to support the horizontal plate 12.

[0023] The horizontal plate 12 is connected to the free ends of the two support pads 112 respectively, and both are vertically connected and extend in a horizontal direction parallel to the ground to form a gantry structure for setting a displacement component in the horizontal direction.

[0024] The movable slide rail 13 is fixed to the horizontal plate 12 and extends along the length of the horizontal plate 12. The two movable slide rails 13 are spaced apart and parallel to each other, and the plane on which the movable slide rails 13 are arranged is a vertical plane perpendicular to the ground. The movable sliders 14 are arranged in pairs on the two movable slide rails 13 and can slide along the movable slide rails 13 to serve as the track structure for the movement of the movable connecting plate 16.

[0025] The movable push cylinder 15 is disposed on one side of the horizontal plate 12, and its driving direction is consistent with the extension direction of the movable slide rail 12. The driving end is fixedly connected to the movable connecting plate 16 to drive the movable connecting plate 16 to move. The movable push cylinder 15 can be a magnetically coupled rodless cylinder, which is existing technology. For example, relevant content is explained in a magnetically coupled rodless cylinder disclosed in Chinese Utility Model CN202122983097.0. Therefore, only a brief description is given here, and its functions and structure are not described in detail.

[0026] The movable connecting plate 16 is a rectangular plate that connects to four movable sliders 14, so that it can reciprocate along the movable slide rail 13 under the drive of the movable push cylinder 15, and serve as the base plate for the lifting mechanism 20, the support structure 30 and the clamping assembly 40.

[0027] The movable buffer 17 is a hydraulic buffer, which is fixed on the horizontal plate 12 and located at both ends of the movable slide rail 13. The sensing ends are all facing the movable connecting plate 16 so that when the movable connecting plate 16 moves to the limit position, the sensing ends touch the edge of the movable connecting plate 16, which plays a role in buffering and limiting, and at the same time facilitates the setting of the corresponding working position.

[0028] The lifting mechanism 20 includes a lifting fixed plate 21 disposed on the movable connecting plate 16, two lifting sliders 22 fixed on the lifting fixed plate 21, two lifting slide rails 23 disposed on the lifting sliders 22, a lifting connecting plate 24 disposed on the lifting slide rails 23, a lifting cylinder 25 fixed on the lifting fixed plate 21 and connected to the lifting connecting plate 24, and a lifting buffer 26 disposed on the lifting connecting plate 24.

[0029] The lifting fixing plate 21 is fixed on the movable connecting plate 16, and the two are in close contact to ensure the stability and reliability of the lifting mechanism 20.

[0030] The lifting sliders 22 are fixed at intervals and parallel to each other on the lifting fixing plate 21. The lifting slide rails 23 are respectively arranged on the lifting sliders 22 and extend in a vertical direction perpendicular to the ground, so that the support structure 30 and the clamping assembly 40 can reciprocate in the vertical direction.

[0031] The lifting connecting plate 24 is spaced apart from and parallel to the lifting fixing plate 21. The lifting slide rail 23 is fixed on the lifting connecting plate 24, so that the track is connected to the lifting fixing plate 21, and the lifting connecting plate 24 can move up and down relative to the lifting fixing plate 21.

[0032] The lifting cylinder 25 is fixed on the lifting fixed plate 21, and the driving end is connected to the lifting connecting plate 24 to provide driving force for the lifting movement of the lifting connecting plate 24.

[0033] The lifting buffer 26 is disposed on the edge of the lifting connecting plate 24, with the sensing end facing a vertical direction perpendicular to the ground. A blocking plate is disposed on the edge of the lifting fixing plate 21 so that the lifting connecting plate 24 can play a buffering and blocking role after it descends to the working position.

[0034] The support structure 30 includes a support main plate 31 perpendicular to the lifting connecting plate 24, four pressing guide columns 32 on the support main plate 31, a support connecting plate 33 spaced apart from the support main plate 31, a press-fit cylinder 34 on the support main plate 31, a sealing ring assembly / disengagement plate 35 spaced apart from the support connecting plate 33, and multiple support connecting columns 36 connecting the support connecting plate 33 and the sealing ring assembly / disengagement plate 35.

[0035] The main support plate 31 is vertically fixed to the lifting connecting plate 24, and the plate surface is parallel to the ground plane, serving as the base plate of the support structure 30. Two ribs can also be vertically fixed to the main support plate 31 and the lifting connecting plate 24 to enhance the structural strength.

[0036] The downward guide post 32 passes vertically through the support main plate 31 to serve as a guide. The downward guide posts 32 are set at the same height, and a connecting structure is provided on the free end of the support main plate 31 on the side away from the support connecting plate 33 for equal height connection, so as to ensure that the downward guide posts 32 maintain a consistent height during the guiding movement, thereby ensuring that the support connecting plate 33 and the sealing ring assembly release plate 35 always remain in a horizontal state parallel to the ground.

[0037] The support connecting plate 33 is located between the support main plate 31 and the sealing ring assembly release plate 35, and is fixed to the other end of the four pressing guide posts 32 to serve as a connection.

[0038] The main body of the press-fit cylinder 34 is fixed on the main support plate 31, and the drive end is connected to the support connecting plate 33 to drive the support connecting plate 33 to move up and down in the vertical direction perpendicular to the ground.

[0039] The sealing ring assembly release plate 35 is provided with a plurality of opening shaft movement holes 351. The opening shaft movement holes 351 are waist-shaped holes, and the length direction of the hole is the clamping direction of the clamping assembly 40. The specific structure and function will be explained in detail in conjunction with the clamping assembly 40 in the afternoon.

[0040] The supporting connecting column 36 fixes and connects the supporting connecting plate 33 and the sealing ring assembly release plate 35. In this embodiment, six supporting connecting columns 36 are provided, located on both sides of the supporting connecting column 36, and the supporting connecting columns 36 on the same side are on the same straight line.

[0041] The clamping assembly 40 includes a gripper cylinder 41 disposed on the lifting connecting plate 24, two spreading grippers 42 disposed on the gripper cylinder 41, and a plurality of positioning spreading shafts 43 disposed on the spreading grippers 42.

[0042] The gripper cylinder 41 is a drive mechanism for driving the gripper. It is existing technology, as mentioned in Chinese invention CN202310870491.4, so it is only briefly described here.

[0043] The spreading jaws 42 are respectively disposed on the two driving ends of the jaw cylinder 41, and move closer or further apart under the drive of the jaw cylinder 41 to control the movement of the positioning spreading shaft 43. The spreading jaws 42 are located between the support connecting plate 33 and the sealing ring assembly release plate 35, and are arranged parallel to both. The spreading jaws 42 are provided with a plurality of support column movement holes 421. The support column movement holes 421 are oblong holes, and the length direction of the hole is the clamping direction of the clamping assembly 40. The support connecting column 36 passes through the support column movement holes 421 so that the spreading jaws 42 are not blocked by the support connecting column 36 when they move under the drive of the jaw cylinder 41.

[0044] The positioning and opening shaft 43 is disposed on the opening jaw 42 and is a cylindrical optical axis extending away from the support connecting plate 33 for insertion into the sealing gasket. The positioning and opening shaft 43 passes through the opening shaft movement hole 351 to ensure that it does not affect the movement of the opening jaw 42. In this embodiment, six positioning and opening shafts 43 are provided, with three shafts per group located on the opening jaw 42. The positioning and opening shafts 43 located on the same opening jaw 42 are on the same straight line, and the spacing is sufficient to allow them to be inserted into the sealing ring to be installed simultaneously.

[0045] In use, the clamping assembly 40 is in a clamped state, and the two spreading jaws 42 approach each other. Then, under the action of the slide bracket 10 and the lifting mechanism 20, they move to the location of the sealing ring to be installed. The positioning spreading shaft 43 is inserted into the reserved hole of the sealing ring. Then, under the driving action of the jaw cylinder 41, the spreading jaws 42 move away from each other, thereby spreading the sealing ring. They then move again to the location of the product to be installed via the dual shafts, and the spread sealing ring is placed on the product. Then, the pressing cylinder 34 drives the sealing ring assembly release plate 35 to press down, pressing the sealing ring off the positioning spreading shaft 43, and the assembly is completed.

[0046] Compared with existing technologies, the sealing gasket assembly device for diaphragm pump assembly provided by this invention, through the setting of the slide table support 10 and the lifting mechanism 20, realizes the dual-axis movement of the clamping component 40, automating material picking and assembly, replacing manual operation, improving assembly capacity, and reducing manual intervention. Furthermore, by setting the support structure 30 and the clamping component 40, and setting the positioning and opening shaft 43 on the gripper, the sealing gasket is opened for easy installation onto the product. Simultaneously, by setting the pressing cylinder 34 and the sealing gasket assembly release plate 35, the opened and moved sealing gasket is pushed out, causing the sealing gasket to retract, thus completing the assembly. The entire process is automated, solving the problem of the current process requiring manual assembly, greatly improving the assembly efficiency of the diaphragm pump, effectively increasing production capacity, and reducing labor costs.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
