Technical Field
[0001] This utility model relates to the field of electromagnetic valve airtightness testing technology, and in particular to an electromagnetic valve airtightness testing mechanism applied to a production line. Background Technology
[0002] In the solenoid valve assembly industry, customers have a need for the automated assembly of bulk materials such as valve body, valve stem, valve seat, sealing ring, spring, spring seat, metal cover plate, armature tube, and hexagonal nut into finished valve bodies.
[0003] The existing technology, CN2024103883113, describes a solenoid valve assembly production line. The existing technology uses automated equipment to automatically assemble the solenoid valves. However, after the solenoid valves are assembled, the airtightness of the assembled solenoid valves still needs to be tested. The existing technology requires additional assembly, which results in low efficiency.
[0004] Therefore, it is necessary to design a solenoid valve airtightness testing mechanism for use on production lines to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a solenoid valve airtightness testing mechanism for use on production lines, in order to overcome the aforementioned shortcomings of the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An airtightness testing mechanism for a solenoid valve applied on a production line includes a production line, characterized in that it further includes an airtightness testing mechanism placed beside the production line. The airtightness testing mechanism includes a column disposed beside the production line, a mounting base disposed on the column, a front limiting mechanism, a rear limiting mechanism, a left limiting mechanism, and a right limiting mechanism disposed around the mounting base, a solenoid valve tooling disposed between the front limiting mechanism, the rear limiting mechanism, the left limiting mechanism, and the right limiting mechanism, and a solenoid valve pickup module disposed on the front side of the mounting base and close to the production line.

DETAILED DESCRIPTION
[0014] REFERENCE Figure 1 The electromagnetic valve gas-tightness detection mechanism applied to the production line comprises a production line and a gas-tightness detection mechanism arranged on the side of the production line.
[0015] The gas-tightness detection mechanism comprises a stand 1 arranged on the side of the production line, a mounting seat 2 arranged on the stand, a front limiting mechanism 3, a rear limiting mechanism 4, a left limiting mechanism 5 and a right limiting mechanism 6 arranged on the four sides of the mounting seat, an electromagnetic valve tooling 7 arranged in the middle of the front limiting mechanism, the rear limiting mechanism, the left limiting mechanism and the right limiting mechanism, and an electromagnetic valve pickup module 8 arranged on the front side of the mounting seat and close to one side of the production line.
[0016] The solenoid valve pickup module 8 includes a mounting base 81 disposed on the front side of the column, a lifting cylinder 82 disposed on the mounting base, a mounting base 83 driven by the lifting cylinder and moving up and down, a rotating cylinder 84 disposed on the mounting base, a rotating rod 85 driven by the rotating cylinder, and suction heads 86 respectively disposed on both sides of the rotating rod; in order to drive the suction heads to pick up the solenoid valve, a vacuum adsorption device is connected to the outside of the suction heads.
[0017] A vacuum adsorption device provides adsorption force, allowing the suction head to remove the solenoid valve from the production line. A lifting cylinder drives the suction head up and down to approach the solenoid valve, where it adheres. The lifting cylinder then moves the suction head upwards to remove the solenoid valve from the production line. A rotary cylinder then rotates the suction head 180° to move it onto a fixture. The lifting cylinder then moves the suction head downwards to place the solenoid valve onto the fixture. The suction head releases its adsorption force, and the solenoid valve is installed on the fixture. The lifting cylinder resets, and after an airtightness test, the suction head moves downwards again to pick up the solenoid valve. It rotates again and returns to the production line. Meanwhile, the other side has a solenoid valve for testing, which is then moved to the fixture for testing. This cycle is repeated for repeated testing.
[0018] The front limiting mechanism, rear limiting mechanism, left limiting mechanism, and right limiting mechanism have the same structure and are respectively set on the front, rear, left, and right sides of the mounting base. Each includes a slide rail 51 set on the mounting base, a drive plate 52 mounted on the slide rail via a slider, a drive cylinder 53 set on the side of the mounting base and driving the drive plate to move, and an airtight plug 54 set on the slider.
[0019] The airtight plugs of the front, rear, left, and right limiting mechanisms are respectively configured to correspond to the front, rear, left, and right air pipes of the solenoid valve. A driving cylinder drives the driving plate to move, simultaneously moving the slider, which in turn moves the airtight plugs. The airtight plug of the front limiting mechanism aligns with the front air pipe of the solenoid valve, and the airtight plug contacts the front air pipe of the solenoid valve, thus blocking the air pipe at the front of the solenoid valve. Similarly, the airtight plug of the rear limiting mechanism contacts the rear air pipe of the solenoid valve, the airtight plug of the left limiting mechanism contacts the left air pipe of the solenoid valve, and the airtight plug of the right limiting mechanism contacts the right air pipe of the solenoid valve, thus completely blocking the air pipes of the solenoid valve. Furthermore, the airtight plugs of the front, rear, left, and right limiting mechanisms are respectively configured to correspond to the front, rear, left, and right air pipes of the solenoid valve, thus blocking the air pipes of the solenoid valve. The airtight plugs of the side limiting mechanism and the right limiting mechanism are connected to an air inlet module, an air outlet module, and an airtightness display module. Each limiting mechanism's airtight plug is connected to a module. For example, the airtight plug of the front limiting mechanism is connected to an air inlet module, and the airtight plug of the rear limiting mechanism is connected to an airtightness display module. The airtight plug of the left limiting mechanism is connected to an air inlet module, and the airtight plug of the right limiting mechanism is connected to an air inlet module, thus forming a circuit. Since the air pipes around the solenoid valve are interconnected and are blocked by airtight plugs during testing, air enters through the air inlet module, while the other air outlet modules are closed. After a period of air intake, the airtightness display module tests the internal airtightness. If there is only leakage, the airtightness is good; if there is leakage, it indicates that there is a problem with the airtightness.
[0020] In order to effectively detect the actual airtightness, an airtightness display module 9 is provided on the rear side of the airtightness detection mechanism; it includes an air pipe, a pressure gauge 91 connected to the air pipe, a pressure sensor 92, and a connector 93 for connection; specifically, the connector of the air pipe is connected to the airtightness plug of the rear limiting mechanism.
[0021] The advantages of this utility model are that this technical solution picks up the solenoid valve on the production line and places it on the airtightness testing mechanism by setting a solenoid valve pickup module on the side of the production line. The solenoid valve is limited around its perimeter by a front limiting mechanism, a rear limiting mechanism, a left limiting mechanism, and a right limiting mechanism. At the same time, the plug is aligned with the air pipe to seal it. The airtightness is tested by ventilation and an airtightness display module. This structure is effectively applied on the production line to assist in the rapid airtightness testing.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
