Description

Technical Field

[0001] This invention relates to the field of electrical machinery and equipment manufacturing, and in particular to a device for inserting a sealing ring into a capped iron cover. Background Technology

[0002] The core component of an electrochemical smoke alarm sensor is the sensor head assembly. This head assembly typically consists of a material wrapped in a capped metal cover pressed into a sealing ring. The material wrapped in the cap reacts with particles in the smoke, altering their physical properties and causing changes in resistance and temperature. By detecting these changes, an alarm is triggered. The capped metal cover is usually assembled and welded together from tiny parts, which are then pressed into the sealing ring. The sealing ring is ensured to tightly wrap around the edge of the cap before being inserted into the sensor end. The sealing ring, with its soft, rubbery seal, prevents other airborne contaminants from entering the sensor's interior.

[0003] The rimmed metal cap assembly is usually very small, and the sealing ring is made of soft rubber, so it is usually not easy to install the rimmed metal cap into the sealing ring. The conventional pressing assembly method often leads to problems such as damage to the sealing ring and improper installation of the rimmed metal cap during the assembly process, resulting in a high defect rate after assembly. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for inserting a sealing ring with a capped iron cover. This device is used to solve the problems of easy damage to the sealing ring, easy misalignment of the installation position, and low automation efficiency in the prior art during the press-fitting process of the sealing ring.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A device for inserting a sealing ring with a capped iron cover, including a sealing ring handling robot;

[0007] It also includes a sealing ring expansion mechanism and an iron cap pressing mechanism;

[0008] The sealing ring expansion mechanism includes a base, on which a nozzle expansion component and a lifting displacement component for driving the nozzle expansion component to move are provided. A sealing ring positioning plate is also embedded in the base.

[0009] The opening assembly includes a swing plate fixing plate, which has several through slots. Two opposing first opening swing plates are hinged in the through slots. Several sets of fixing plates are embedded in the swing plate fixing plate, each set consisting of two opposing fixing plates. A second opening swing plate is hinged to the inner side of the fixing plate. The first and second opening swing plates form an enclosing state. The lower sides of the first and second opening swing plates correspond to the sealing ring on the sealing ring positioning plate.

[0010] The iron cap pressing mechanism includes a three-axis manipulator, and the output end of the three-axis manipulator is fixed with several grippers or pneumatic suction heads for gripping the iron cap.

[0011] The sealing ring handling robot places the sealing ring on the sealing ring positioning plate. The output end of the nozzle expansion component moves to the inner wall of the sealing ring on the sealing ring positioning plate. Then, the iron cap pressing mechanism pushes the iron cap through the nozzle expansion component and presses it into the corresponding sealing ring. During the pressing process, the rim of the capped iron cap applies force to the inner walls of the first and second expansion flaps. When the first and second expansion flaps are under pressure, their lower ends expand outward, causing the upper part of the sealing ring to expand.

[0012] In one or more embodiments of the present invention, the lifting displacement assembly includes a slide plate fixed to a base via a linear slide rail, a cylinder seat fixed to the side of the base, a displacement cylinder fixed to the cylinder seat, a connecting block fixed to the output end of the displacement cylinder, one end of the connecting block fixed to the slide plate, four sliding shafts fixed to the slide plate, a lifting plate fixed to the sliding shafts via bushings, a lifting cylinder fixed to the lifting plate, the output end of the lifting cylinder fixed to the slide plate via a connecting seat, a component fixing plate fixed to the lower side of the lifting plate, and the opening nozzle assembly fixed to the lower side of the component fixing plate.

[0013] In one or more embodiments of the present invention, a blocking plate is fixed to one side of the slide plate, and the lower end face of the blocking plate slides in contact with the upper surface of the base and the sealing ring positioning plate.

[0014] In one or more embodiments of the present invention, a limiting plate is fixed to the outer side of the base, a first buffer post is installed on the limiting plate, a lower baffle is fixed on the base, an upper baffle is fixed to the lower side of the slide plate opposite to the lower baffle, a second buffer post is installed on the lower baffle, and a third buffer post is installed on the lifting plate.

[0015] In one or more embodiments of the present invention, the first expanding swing plate and the second expanding swing plate are fixed by rotation via a rotating shaft. The first expanding swing plate and the second expanding swing plate have the same structure. The first expanding swing plate is a fan-shaped structure with its inner wall forming an arc-shaped surface.

[0016] In one or more embodiments of the present invention, the outer surfaces of the first expansion swing piece and the second expansion swing piece are provided with arc-shaped grooves, and a collar is fitted inside the arc-shaped grooves.

[0017] In one or more embodiments of the present invention, the sealing ring positioning plate is provided with a plurality of sealing ring grooves for placing the sealing ring, the middle part of which is a hollow cylindrical hole penetrating the sealing ring positioning plate, and the upper end of the hollow cylindrical hole has a raised limiting protrusion.

[0018] The beneficial effects of this invention are:

[0019] This invention proposes a device for inserting a sealing ring into a capped iron cover. When the capped iron cover is pressed in, force is applied to the inner walls of the first and second expanding flaps. When pressure is applied internally, the lower end expands outward, causing the upper part of the sealing ring to expand, allowing the capped iron cover to be pressed into the groove of the sealing ring. This prevents damage to the sealing ring and ensures a more secure installation. The device has a compact structure with multiple nozzles arranged side-by-side at intervals, improving the quality and efficiency of pressing the capped iron cover into the sealing ring during mass production.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] In this embodiment, as Figures 1 to 7 As shown, a device for inserting a sealing ring with a capped iron cover includes a sealing ring handling robot, a sealing ring expansion mechanism, and an iron cover pressing mechanism.

A sealing ring positioning plate 2 is also embedded in the base 1. The sealing ring handling robot places the sealing ring on the sealing ring positioning plate 2. The output end of the nozzle expansion component moves to the inner wall of the sealing ring on the sealing ring positioning plate 2. Then, the iron cover pressing mechanism passes through the nozzle expansion component and presses it into the corresponding sealing ring. During the pressing process, the sealing ring is expanded by the nozzle expansion component.

[0029] In this embodiment, the sealing ring positioning plate holds eight sealing rings within two years. The external robotic arm, sealing ring expansion mechanism, and iron cap pressing mechanism all perform the sealing ring installation work in eight positions, thereby further improving work efficiency. In this embodiment, a slot is provided on the inner wall of the sealing ring, and the slot is adapted to the cap edge of the iron cap.

[0030] In one or more embodiments of the present invention, the opening assembly includes a fixing plate 3, the fixing plate 3 having a plurality of through slots, two opposing first opening swing pieces 4 hinged in the through slots, the fixing plate 3 having a plurality of sets of fixing pieces 5 embedded therein, each set consisting of two opposing fixing pieces 5, the inner side of the fixing piece 5 being hinged to a second opening swing piece 6, the first opening swing piece 4 and the second opening swing piece 6 forming an enclosed state, the lower side of which corresponds to the sealing ring on the sealing ring positioning plate 2.

[0031] In this embodiment, the first expanding swing plate 4 and the second expanding swing plate 6 are hinged together, and their lower ends have the freedom to swing inward and outward. When pressure is received inside, their lower ends expand outward, thereby expanding the sealing ring so that it can be installed on the cap. The lower ends of the first expanding swing plate 4 and the second expanding swing plate 6 only expand the upper half of the sealing ring, and the inner walls of the first expanding swing plate 4 and the second expanding swing plate 6 only abut against the cap rim of the cap.

[0032] In one or more embodiments of the present invention, the lifting displacement assembly includes a slide plate 7 fixed to a base 1 via a linear slide rail. A cylinder seat is fixed to the side of the base 1, and a displacement cylinder 8 is fixed to the cylinder seat. A connecting block 9 is fixed to the output end of the displacement cylinder 8. One end of the connecting block 9 is fixed to the slide plate 7. Four sliding shafts 10 are fixed to the slide plate 7. A lifting plate 11 is fixed to the sliding shaft 10 via a bushing. A lifting cylinder 12 is fixed to the lifting plate 11. The output end of the lifting cylinder 12 is fixed to the slide plate 7 via a connecting seat. A fixing plate 13 is fixed to the lower side of the lifting plate 11. The drive nozzle expansion assembly is fixed to the lower side of the fixing plate 13.

[0033] In this embodiment, the lifting and displacement component enables the nozzle expansion component to move and lift, so as to place the sealing ring and the nozzle expansion component.

[0034] In one or more embodiments of the present invention, a blocking plate 14 is fixed on one side of the slide plate 7, and the lower end face of the blocking plate 14 slides in contact with the upper surface of the base 1 and the sealing ring positioning plate 2.

[0035] In this embodiment, the baffle plate 14 has an overall "L" shaped structure, and the extended end of its lower bent portion is provided with several limiting grooves. A stepped groove is also formed on the lower side of the limiting groove. The sealing ring on the sealing ring positioning plate 2 is located in the stepped groove, and its two first expansion swing pieces 4 and the lower side of the second expansion swing piece 6 located on the inner side are limited by the limiting groove.

[0036] In one or more embodiments of the present invention, a limiting plate 15 is fixed on the outer side of the base 1, a first buffer post is installed on the limiting plate 15, a lower baffle is fixed on the base 1, an upper baffle is fixed on the lower side of the slide plate 7 opposite to the lower baffle, a second buffer post is installed on the lower baffle, and a third buffer post is installed on the lifting plate 11.

[0037] In this embodiment, the displacement of the opening assembly is limited by the setting of the first buffer column, the second buffer column and the third buffer column.

[0038] In one or more embodiments of the present invention, the first expanding swing piece 4 and the second expanding swing piece 6 are fixed by rotation via a rotating shaft. The first expanding swing piece 4 and the second expanding swing piece 6 have the same structure. The first expanding swing piece 4 is a fan-shaped structure with its inner wall forming an arc-shaped surface.

[0039] In one or more embodiments of the present invention, the outer surfaces of the first expanding swing piece 4 and the second expanding swing piece 6 are provided with arc-shaped grooves 16, and a collar is fitted inside the arc-shaped grooves.

[0040] In this embodiment, by setting the collar, when there is no external force squeezing the first expansion swing piece 4 and the second expansion swing piece 6 from the inside, the collar will gather the first expansion swing piece 4 and the second expansion swing piece 6, so that they will not swing randomly.

[0041] In one or more embodiments of the present invention, the sealing ring positioning plate 2 is provided with a plurality of gasket grooves for placing gaskets, the middle part of which is a hollow cylindrical hole penetrating the sealing ring positioning plate 2, and the upper end of the hollow cylindrical hole has a raised limiting protrusion 201.

[0042] In this embodiment, the pressed-in cap with a brim is limited by the limiting protrusion 201.

[0043] In one or more embodiments of the present invention, the iron cover pressing mechanism includes a three-axis manipulator 17, and the output end of the three-axis manipulator 17 is fixed with a plurality of grippers or pneumatic suction heads for gripping the iron cover.

[0044] Working principle of this invention:

[0045] The sealing ring is installed on the sealing ring positioning plate 2 by a robotic arm. Then, the lifting and displacement component drives the nozzle expansion component to reach the upper side of the sealing ring positioning plate 2. After the position is aligned, the three-axis robotic arm 17 uses a gripper or pneumatic suction head to push the capped iron cover through the middle of the first expansion swing plate 4 and the second expansion swing plate 6. During the pressing process, the capped iron cover applies force to the inner wall of the first expansion swing plate 4 and the second expansion swing plate 6. When there is internal pressure, its lower end expands outward, so that the upper part of the sealing ring expands so that the capped iron cover is pressed into the groove of the sealing ring. After pressing, the main body of the capped iron cover will not squeeze the first expansion swing plate 4 and the second expansion swing plate 6. At this time, the nozzle expansion component can be removed to take out the finished product.
