A plug-in device for transformer production

Abstract

A plug-in device for transformer production belongs to the technical field of transformers. It solves the problem that the existing transformer plug-in installation device can only push a fixed number of plugs when in use, resulting in a narrow range of applications. The present invention drives the screw to rotate by rotating the adjustment knob at the groove, which can then drive the adjustment plate, the sliding column and the limit plate to move, thereby adjusting the space above the inside of the material trough. After adjustment, multiple material troughs can accommodate different numbers of plugs. When the material disc rotates, the plugs in the discharge box fall into the inside of the material trough, and then the plugs are pushed onto the transformer through the pushing mechanism and the pressing mechanism. This realizes that different numbers of plugs can be inserted each time according to different transformers to meet production requirements, with high work efficiency and a wide range of applications.

Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a sheet inserting device for transformer production. Background Art

[0002] A transformer is an electrical device used to change the voltage and current of alternating current. It is mainly composed of components such as an iron core, a coil, and plugs. Transformers are widely used in power systems, electronic equipment, home appliances, and industrial manufacturing. The plug device is a device used to install the plugs on the transformer in order to improve installation efficiency.

[0003] Patent publication number CN104517717B discloses a high-efficiency transformer core inserting machine. The machine comprises upper and lower guide rails that are stacked and offset from each other, a chute for stacking core sheets, and horizontally arranged first and second cylinders. The piston rod of the first cylinder is connected to a pusher block, and the piston rod of the second cylinder is connected to a feed rack for placing transformer windings. An electrical box with a limit switch is located on one side of the upper and lower guide rails. This invention utilizes cylinders on either side to push the transformer windings and core, respectively, to complete the core inserting process on the offset and stacked guide rails. The limit switch automatically triggers the cylinders to complete the reciprocating motion, improving the efficiency and precision of transformer core inserting operations and preventing product quality defects caused by human error.

[0004] In order to increase current capacity and reduce electromagnetic interference, multiple blades are often installed in an overlapping manner each time the blades are installed, and a single blade is placed for the first and last time. However, when performing the blade insertion operation, the existing blade device can only install one blade or a fixed number of blades on the left and right sides at a time. Considering that the number of blades installed each time when inserting transformer blades is different, the existing blade device can only be installed on one side, and then installed on the other side after the appropriate number of blades are installed, which will lead to overall low efficiency.

[0005] To solve the above problems, a sheet inserting device for transformer production is proposed. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to solve the technical problem that the existing transformer plug installation device can only push a fixed number of plugs when in use, resulting in a limited scope of application, such as Figures 1-6 As shown, the following preferred technical solutions are provided:

[0029] A plug-in device for transformer production includes a workbench 1 and a pressing mechanism 6 disposed in the middle of the top of the workbench 1, and also includes a material discharge box 3 disposed on both sides of the top of the workbench 1. Rotating material dispensing trays 2 are also rotatably disposed on both sides of the top of the workbench 1. Material dispensing troughs 21 are evenly distributed on the top of the rotating material dispensing tray 2. The material dispensing troughs 21 are used to accommodate plug-in sheets. The interior of the material dispensing troughs 21 is provided with an adjustment mechanism 4. The adjustment mechanism 4 is used to adjust the space above the interior of the material dispensing trough 21 and thereby adjust the number of plug-in sheets accommodated.

[0030] The top of the workbench 1 is located above the rotating material-taking tray 2 and is provided with a pushing mechanism 5. The pushing mechanism 5 is used to push the inserts in the material-taking troughs 21 on both sides of the pressing mechanism 6 outward into the transformer on the pressing mechanism 6. The pressing mechanism 6 includes a lower elastic base 61 installed on the workbench 1, a second telescopic cylinder 62 installed on the top of the workbench 1, and an upper elastic base 63 installed below the second telescopic cylinder 62. The lower elastic base 61 and the upper elastic base 63 are used to position the transformer, and the second telescopic cylinder 62 is used to control the transformer to move downward. The top edge of the rotating material-taking tray 2 is located above the material-taking trough 21 and a limit baffle 23 is installed. The limit baffle 23 It is used to ensure that the insert can only slide horizontally before leaving the feeding chute 21. The transformer insert is pre-placed in the feeding box 3. The upper space inside the feeding chute 21 is changed by adjusting the adjustment mechanism 4. Then, when the feeding tray 2 is rotated, the insert in the feeding box 3 falls into the inside of the feeding chute 21. Then, the insert on both sides of the pressing mechanism 6 is pushed outward in sequence by the pushing mechanism 5. When the insert in the feeding chute 21 moves to the bottom of one side of the transformer, the second telescopic cylinder 62 is used to force the transformer to move downward, and the installed insert is forced to move upward. At this time, the insert in the feeding chute 21 is facing the installation slot on the transformer, and the insert is pushed onto the transformer by the pushing mechanism 5.

[0035] The workbench 1 is provided with grooves 11 running through the upper and lower parts, and there are two groups of grooves 11. The grooves 11 are used to adjust the adjustment mechanism 4 on the rotating material picking tray 2 from the bottom of the workbench 1. When adjusting, the screw 44 is driven to rotate by rotating the adjustment knob 441, which can drive the adjustment plate 43, the sliding column 42 and the limit plate 41 to move, thereby adjusting the space above the inside of the material picking trough 21.

[0036] A motor 24 is fixedly connected to the bottom of the workbench 1. The motor 24 passes through the workbench 1 upward and is fixedly connected to the middle of the bottom of the rotating material taking tray 2. A preset groove 22 is provided in the upper middle part of the interior of the rotating material taking tray 2. The preset groove 22 is connected to the material taking groove 21.

A first telescopic cylinder 53 is installed on one side of the guide plate 511. The output end of the first telescopic cylinder 53 is fixedly connected to the pushing rod 52. When the pushing rod 52 is retracted, the pushing rod 52 can be moved, and the insert is pushed to the side of the transformer through the gap between the two sets of limit plates 41 through the pushing plate 521.

[0038] The second telescopic cylinder 62 is fixedly connected to the top of the workbench 1 through the second fixed bracket 621. The top of the workbench 1 is provided with a guide groove 12. The lower elastic base 61 includes a guide rod 611 slidably connected to the inside of the guide groove 12. The top of the guide rod 611 is fixedly connected to the lower base 612.

When the second telescopic cylinder 62 extends half its length, the upper base 634 and the lower base 612 position the transformer. When the push plate 521 pushes the insert to the bottom of one side of the transformer, the second telescopic cylinder 62 extends, causing the transformer to move downward, and the insert located in the material trough 21 limits the insert on the transformer. When the installation slot on the transformer is aligned with the insert in the material trough 21, the push plate 521 then extends to install the insert.

[0040] Specifically, first, the transformer plug is placed in the discharge box 3 in advance, and the screw 44 is driven to rotate by rotating the adjusting knob 441 at the groove 11, which can drive the adjusting plate 43, the sliding column 42 and the limit plate 41 to move, thereby adjusting the space above the inside of the material chute 21. Then, when the motor 24 drives the rotating material disc 2 to rotate, the plug in the discharge box 3 falls into the inside of the material chute 21. Then, when the pushing rod 52 is retracted, the pushing rod 52 can be moved, and the pushing plate 521 passes through the gap between the two sets of limit plates 41 to push the plug to the side of the transformer. When the plug in the material chute 21 moves to the bottom of one side of the transformer, the second telescopic cylinder 62 is used to force the transformer to move downward, causing the installed plug to move upward. At this time, the plug in the material chute 21 is facing the installation slot on the transformer, and the pushing mechanism 5 can push the plug onto the transformer.
