Description

Technical Field

[0001] This invention belongs to the field of mechanical assembly technology, and specifically relates to an automated assembly table for iron core components. Background Technology

[0002] Iron core assemblies are mostly installed inside various types of circuit breakers. They play an important role in magnetic field conduction and stability, and are one of the key components for achieving current control and disconnection.

[0003] Currently, the assembly of iron core components is done manually. Since iron core components involve a large number of parts, manual assembly is inefficient and reduces the product qualification rate. Therefore, it is necessary to design an automated assembly station for iron core components to replace manual assembly and improve efficiency. Summary of the Invention

[0004] The present invention addresses the technical problems mentioned in the background section by employing the following technical solution:

[0005] A method for assembling iron core components using an automated assembly table is disclosed. The automated assembly table includes a base plate, on the top of which a lower plate is slidably mounted via a sliding assembly. A workpiece placement plate is mounted on the top of the lower plate. Each workpiece placement plate has a placement hole for placing an iron block, a movable rod, and a spring. A tray is mounted on the top of the workpiece placement plate, and the tray has multiple through holes matching the placement holes for placing an armature and a housing. A pressing mechanism is mounted on one side of the top of the base plate to press the tray, causing the tray and the workpiece placement plate to combine, thereby assembling the movable rod, iron block, spring, armature, and housing into an iron core component.

[0006] It should be noted that the outer shell is first placed in each through hole, and the armature is placed inside the outer shell; the movable rod is first placed in each placement hole, and then an iron block is sleeved on the movable rod. A spring is sleeved on both the iron block and the movable rod. When the pressing mechanism presses, a part of the movable rod, the iron block and the spring are located inside the outer shell, and one end of the spring is in contact with the armature, and the bottom of the armature is combined with the movable rod to form the iron core assembly.

[0007] As a preferred example, the sliding assembly includes a slide rail and a slider. The slide rail is mounted on the top of the base plate, and the slider is mounted on the bottom of the lower plate, and the slider slides on the slide rail.

[0008] Furthermore, the bottom of the slider is provided with a groove, and the slide rail is provided with a protrusion that matches the groove. The groove on the slider slides on the protrusion on the slide rail, allowing the slider to move smoothly along the slide rail. There are two slide rails. Two limiting blocks and two support blocks are installed on the base plate by bolts. Each limiting block is located at one end of each slide rail, and each support block is located on the side wall of one end of each slide rail. One of the support blocks is located near one of the limiting blocks. Limiting components are also installed on the base plate by screws. The limiting components are located at the other end of the two slide rails. The limiting blocks and limiting components are used to indicate the movement position of the slider on the slide rail.

[0009] As a preferred example, the lower plate and the workpiece placement plate are fixed together by a fastening assembly.

[0010] Furthermore, the fastening assembly includes fasteners and fastening bolts. Bolt holes are installed on both the lower plate and the workpiece placement plate. The fasteners are fitted into the bolt holes of the lower plate and the workpiece placement plate and are fixed to the lower plate by screws. The fastening bolts are threaded into the fasteners, so that the lower plate and the workpiece placement plate are connected.

[0011] As a preferred example, the workpiece placement plate and the pallet are positioned by locating pins.

[0012] Furthermore, the workpiece placement plate is provided with insertion holes, and the tray is provided with positioning holes. Positioning pins are placed on both the insertion holes and the positioning holes to correspond to the workpiece placement plate.

[0013] As a preferred example, the pressing mechanism includes a motor, a lead screw, a connector, a lifting platform, and a support column. There are multiple support columns, the bottoms of which are fixed to a base plate, and a horizontal plate is installed on the tops of which. The fixed end of the motor is fixedly sleeved on the horizontal plate, and the lifting platform is slidably sleeved on the multiple support columns. One end of the lead screw is connected to the output end of the motor, and the lifting platform is threadedly sleeved on the lead screw through a connector.

[0014] Furthermore, there are four pillars.

[0015] As a preferred example, the lifting platform includes a pressure plate, a connecting plate, a through-pipe connector, and a lifting plate. The lifting plate is slidably sleeved on the support column through the through-pipe connector. One end of the connecting plate is connected to the bottom of the lifting plate, and the other end of the connecting plate is connected to the pressure plate. Both the connecting plate and the support column are vertical on the base plate. The pressure plate is provided with a protrusion that matches the tray.

[0016] Furthermore, a handle is connected to one side wall of the lower plate, which can be used to push the lower plate to move on the base plate.

[0017] The beneficial effects of this invention are as follows: This invention sets a lower plate on the base plate, fixes a workpiece placement plate on the lower plate, and then uses positioning pins to cooperate with the tray to complete the placement of iron core materials. A motor drives a lead screw to make the pressure plate press the head of the workpiece to complete the assembly. In addition, this invention sets multiple through holes on the surface of the tray and sets corresponding placement holes on the workpiece placement plate to cooperate with each other, so that multiple components can be assembled at one time, improving assembly efficiency.

Detailed Implementation

[0024] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0025] like Figure 1-5As shown, an assembly method for iron core components using an automated assembly table is described. The automated assembly table includes a base plate 1, a lower plate 2 slidably mounted on the top of the base plate 1 via a sliding component 5, and a workpiece placement plate 3 mounted on the top of the lower plate 2. Each workpiece placement plate 3 has a placement hole 31 for placing an iron block, a movable rod, and a spring, respectively. A tray 4 is provided on the top of the workpiece placement plate 3, and multiple through holes 41 matching the placement holes 31 are provided on the tray 4 for placing an armature and a housing, respectively. A pressing mechanism is installed on one side of the top of the base plate 1 to press the tray 4, so that the tray 4 and the workpiece placement plate 3 are combined, thereby assembling the movable rod, iron block, spring, armature, and housing into an iron core component.

[0026] It should be noted that the outer shell is first placed in each through hole 41, and the armature is placed inside the outer shell; the movable rod is first placed in each placement hole 31, and then an iron block is sleeved on the movable rod. A spring is sleeved on both the iron block and the movable rod. When the pressing mechanism presses, a part of the movable rod, the iron block and the spring are located inside the outer shell, and one end of the spring is in contact with the armature, and the bottom of the armature is combined with the movable rod to form the iron core assembly.

[0027] The sliding assembly 5 includes a slide rail 51 and a slider 52. The slide rail 51 is installed on the top of the base plate 1, and the slider 52 is installed on the bottom of the lower plate 2. The bottom of the slider 52 is provided with a groove, and the slide rail 51 is provided with a protrusion that matches the groove. The groove on the slider 52 slides on the protrusion on the slide rail 51, so that the slider 52 moves smoothly along the slide rail 51. There are two slide rails 51. Two limit blocks 53 and two support blocks 54 are installed on the base plate 1 by bolts. Each limit block 53 is located at one end of each slide rail 51, and each support block 54 is located on the side wall of one end of each slide rail 51. One of the support blocks 54 is located near one of the limit blocks 53. Limiting elements 55 are also installed on the base plate 1 by screws. The limiting elements 55 are located at the other end of the two slide rails 51. The limit blocks 53 and the limiting elements 55 are used to limit the movement position of the slider 52 on the slide rail 51.

[0028] The purpose of adopting the above scheme is to set a set of slide rails 51 on the base plate 1 and a set of sliders 52 on the lower plate 2, so that the lower plate 2 and the workpiece placement plate 3 can be quickly moved to the assembly position and the loading position, so as to facilitate the movement of the lower plate 2 and the workpiece placement plate 5 after assembly.

[0029] Both the lower plate 2 and the workpiece placement plate 3 are equipped with bolt holes 6. Fasteners 7 are fitted into the bolt holes 6 of the lower plate 2 and the workpiece placement plate 3 and are fixed to the lower plate 2 by screws. Fastening bolts 8 are threaded into the fasteners 7, so that the lower plate 2 and the workpiece placement plate 3 are connected.

[0030] The workpiece placement plate 3 is provided with an insertion hole 9, and the tray 4 is provided with a positioning hole 10. The insertion hole 9 and the positioning hole 10 are both provided with a positioning pin 11, which is used to align the tray 4 with the workpiece placement plate 3.

[0031] It should be noted that there is a certain gap between the tray 4 and the workpiece placement plate 3 through the positioning pin 11. The purpose is to facilitate the pressing mechanism to press the tray 4, so that the tray 4 moves towards the workpiece placement plate 3 until the whole formed by the outer shell and armature on the tray 4 and the whole formed by the movable rod, spring and iron block on the workpiece placement plate are combined to form the iron core assembly.

[0032] It should be noted that after the workpiece placement plate 3 and the lower plate 2 are fixed, and the spring, movable rod and iron block are placed on the workpiece placement plate 3, the tray 4 is then placed on the workpiece placement plate 3 and positioned by the positioning pin 11, so that the through hole 41 on the tray 4 corresponds to the placement hole 31 on the workpiece placement plate 3. That is, the whole formed by the outer shell and armature on the tray 4 corresponds to the whole formed by the movable rod, spring and iron block on the workpiece placement plate 3.

[0033] The pressing mechanism includes a motor 12, a lead screw 13, a connector 14, a lifting platform 15, and support columns 16. There are multiple support columns 16, and the bottoms of the multiple support columns 16 are fixed to the base plate 1. The tops of the multiple support columns 16 are mounted on a horizontal plate 17. The fixed end of the motor 12 is fixedly sleeved on the horizontal plate 17. The lifting platform 15 is slidably sleeved on the multiple support columns 16. One end of the lead screw 13 is connected to the output end of the motor 12. The lifting platform 15 is threadedly sleeved on the lead screw 13 through the connector 17.

[0034] There are four pillars in pillar 16.

[0035] The lifting platform 15 includes a pressure plate 151, a connecting plate 152, a through-pipe connector 153, and a lifting plate 154. The lifting plate 154 is slidably sleeved on the support column 16 through the through-pipe connector 153. One end of the connecting plate 152 is connected to the bottom of the lifting plate 154, and the other end of the connecting plate 152 is connected to the pressure plate 151. Both the connecting plate 152 and the support column 16 are vertical on the base plate 1. The pressure plate 151 is provided with a protrusion that matches the tray 4.

[0036] When the entire assembly formed by the lower plate 2, workpiece placement plate 3, and pallet 4 slides to the position of the limit block 53 with the assistance of the slider 52 and the slide rail 51, the motor 12 is then started. The output end of the motor 12 begins to rotate, thereby driving the transmission of the lead screw 13, which in turn drives the lifting plate 154 to move on the support column 16. This, in turn, drives the connecting plate 152 and the pressure plate 151 connected to the connecting plate 152 to move up and down relative to the bottom plate 1. This allows the pressure plate 151 to press the pallet 4 and workpiece placement plate 3, so that the entire assembly formed by the outer shell and armature and the entire assembly formed by the movable rod, spring, and iron block are combined into an iron core assembly.

[0037] A handle 18 is connected to one side wall of the lower plate 2, and the lower plate 2 can be pushed to move on the base plate 1 by holding the handle 18.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claims. The scope of protection of this invention is defined by the appended claims and their equivalents.
