Description

Technical Field

[0001] The utility model relates to the technical field of transformer tinning, in particular to an auxiliary jig for tinning transformer pins. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation (magnetic saturation transformer). For small transformers, multiple sets of pins are set on one side. The pins are used for soldering on the circuit board. In order to improve the solderability, corrosion resistance, and conductivity of the pins, they need to be tinned. The tinning process can be completed by manually immersing the pins directly in the tin pool for a while. However, tinning the transformer is inefficient, and the depth of the pins immersed in the tin pool varies. Therefore, it is necessary to produce a transformer pin tinning auxiliary jig to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a transformer pin tinning auxiliary jig to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] A transformer pin tinning auxiliary jig includes a first fixed block, a second fixed block, a first rotating block, a second rotating block, a mounting base, a limiting column and a magnetic pressure plate. The left side of the first rotating block is rotatably mounted on the right end of the first fixed block, and the right side of the second rotating block is rotatably mounted on the left end of the second fixed block. The left and right ends of the mounting base are respectively fixed on the first rotating block and the second rotating block. Multiple groups of limiting columns are provided and are evenly fixed above the mounting base. The limiting columns are made of metal, and the magnetic pressure plate is fixed above the multiple groups of limiting columns by magnetic force.

[0006] Further description of the present invention: The first fixing block and the second fixing block are both regular quadrangular prisms.

[0007] Further description of the present invention: The width of the mounting base plate is the same as the height of the first fixing block and the height of the second fixing block.

[0008] Further description of the utility model: a plurality of groups of threaded holes are evenly arranged on the installation base plate, the lower end of the limiting column is threadedly connected to the threaded hole, and a hexagonal groove is opened above the limiting column.

[0009] Further description of the utility model: The outer periphery of the upper end of the limiting column is provided with a rounded corner.

[0010] Further description of the utility model: It also includes a rotating handle, the left end of the rotating handle is bent downward and fixedly connected to the right end of the mounting base.

[0011] The beneficial effects of the present invention are as follows: a pin is provided on one side of the small transformer. For some types of transformers, the shape is annular with a central through hole in the middle. The side of the small transformer with the pin is facing upward, and the central through hole is placed on the limit column. At this time, the pin corresponds to the front and back sides of the mounting base. After repeatedly placing multiple groups of small transformers, the magnetic pressure plate is placed on the limit column. Due to the magnetic force, the pressure plate presses the multiple groups of small transformers simultaneously and quickly, thereby completing the batch fixation of the small transformers. For small transformers without a hole in the middle, the small transformer can also be placed between two adjacent groups of limit columns for fixation. The tin pool is a container containing tin liquid. After the small transformer is fixed, the first fixing block and the second fixing block are respectively placed on both sides of the tin pool container, that is, the mounting base is across the tin liquid. Then, the mounting base is rotated forward to tin all the pins on the front side. Then, the mounting base is rotated backward to tin all the pins on the rear side in the same way. The advantage of this design is that it can quickly locate and clamp batches of small transformers, and can quickly and batch-wise tin their pins, thereby improving the efficiency and effect of tinning.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 4As shown, a transformer pin 091 tinning auxiliary fixture includes a first fixed block 01, a second fixed block 02, a first rotating block 03, a second rotating block 04, a mounting base 05, a limiting column 06 and a magnetic pressure plate 07. The left side of the first rotating block 03 is rotatably mounted on the right end of the first fixed block 01, and the right side of the second rotating block 04 is rotatably mounted on the left end of the second fixed block 02. The left and right ends of the mounting base 05 are respectively fixed on the first rotating block 03 and the second rotating block 04. The limiting columns 06 are arranged in multiple groups and are evenly fixed above the mounting base 05. The limiting columns 06 are made of metal, and the magnetic pressure plate 07 is fixed above the multiple groups of limiting columns 06 by magnetic force.

[0021] A pin 091 is provided on one side of the small transformer 09. For some models of transformers, its shape is annular with a central through hole 092 in the middle. The side of the small transformer 09 with the pin 091 is facing upward, and the central through hole 092 is placed on the limit column 06. At this time, the pin 091 corresponds to the front and back sides of the mounting base 05. After repeatedly placing multiple groups of small transformers 09, the magnetic pressure plate 07 is placed on the limit column 06. Due to the action of magnetic force, the pressure plate presses multiple groups of small transformers 09 simultaneously and quickly, thereby completing the batch fixation of the small transformers 09. For small transformers 09 without a hole in the middle, the small transformer 09 can also be placed between two adjacent groups of limit columns 06 for fixation. The tin pool is a container filled with molten tin. After the small transformer 09 is secured, the first and second fixing blocks 01 and 02 are placed on either side of the tin pool, with the mounting base 05 positioned across the molten tin. Next, the mounting base 05 is rotated forward to tin all the front pins 091. Then, the mounting base 05 is rotated backward to tin all the rear pins 091 in the same manner. This design offers the advantage of quickly positioning and clamping batches of small transformers 09 and rapidly and efficiently tinning their pins 091 in batches, improving the efficiency and effectiveness of tinning.

[0022] The first fixing block 01 and the second fixing block 02 are both regular quadrangular prisms. When the first fixing block 01 and the second fixing block 02 are placed on the container, each plane on the first fixing block 01 and the second fixing block 02 can be used as a bottom surface, which is convenient for operation.

[0023] The width of the mounting base 05 is the same as the height of the first fixing block 01 and the height of the second fixing block 02, so that when the mounting base 05 is rotated forward 90° or backward 90°, the side of the mounting base 05 just touches the plane of the top of the container, limiting the further rotation of the mounting base 05. At this time, the pin 091 is just vertically inserted into the tin liquid, which makes it easy to control the depth of the pin 091 immersed in the tin liquid.

[0024] The mounting base plate 05 is evenly distributed with multiple sets of threaded holes 051, with the lower ends of the limiting posts 06 being threadedly connected to the threaded holes 051. A hexagonal groove 061 is formed above the limiting posts 06. The hexagonal groove 061 allows for quick installation of the limiting posts 06 using a hexagonal screwdriver. The multiple sets of threaded holes 051 on the mounting base plate 05 can be flexibly selected based on the size of the small transformer 09. The bottom of the limiting posts 06 is threadedly mounted on the mounting base plate 05, and the depth of the threads can be easily adjusted to adjust the height of the limiting posts 06.

[0025] The upper periphery of the limiting column 06 is provided with a rounded corner, which has a guiding effect on the placement of the small transformer 09, facilitating the rapid placement of the small transformer 09.

[0026] In this design, a rotating handle 08 is also included, the left end of which is bent downward and fixedly connected to the right end of the mounting base 05.

[0027] By rotating the handle 08, the mounting base plate 05 can be rotated more conveniently, and the operator can be prevented from directly touching the tin liquid.

[0028] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
