Description

Technical Field

[0001] The utility model relates to the technical field of transformer welding, in particular to an arrangement limiting device for continuously welding transformers. Background Art

[0002] After winding, the winding pins of the transformer need to be welded. During the welding process, the transformer needs to be clamped and fixed. For the welding operation of small transformers, due to their small volume, it is not easy to apply too much clamping force. Using conventional clamping tools is likely to cause damage to the transformers. When clamping in batches, some transformers are likely to become loose and displaced due to insufficient clamping, unable to meet the clamping requirements for continuously welding multiple transformers at one time. Therefore, usually, small transformers are welded one by one, which seriously affects the welding efficiency of small transformers. Summary of the Invention

Description of the Drawings

[0011] Att Figure 1 is a schematic diagram of the overall structure of an embodiment of the present invention;

[0012] Att Figure 2 is an exploded view of the overall structure of an embodiment of the present invention;

[0013] Att Figure 3 is a schematic diagram of the structure of the pressing cover of an embodiment of the present invention. Detailed Embodiment

[0014] The present invention will be further described in detail below with reference to the drawings.

[0015] As shown in the attach Figures 1-3 The arrangement limiting device for continuously welding transformers includes a receiving groove 1. A plurality of transformers are arranged along the length direction of the receiving groove 1, and the groove width of the receiving groove 1 is adapted to the size of the transformers; the end of the transformer with pins is attached to the inner groove wall of the receiving groove 1, and adjacent transformers are in contact with each other; a pressing cover 2 is arranged at the opening of the receiving groove 1. The pressing cover 2 presses a plurality of the transformers against the bottom of the receiving groove 1, and the pressing cover 2 and the receiving groove 1 are fixed by mutual adsorption; a gap 3 is formed between the edge of the pressing cover 2 and the edge of the port of the receiving groove 1, and the pins extend through the gap 3.

[0016] This solution can clamp and fix multiple transformers neatly arranged to form an integral transformer array. This integral can be installed and disassembled relative to the welding equipment, thereby realizing continuous welding of transformers, and can perform welding and clamping operations synchronously, greatly improving the welding efficiency. Specifically, multiple transformers are quickly arranged neatly and closely attached to each other through the accommodation groove, and then the neatly arranged transformers are limited in the groove by the pressing cover. By using the mutual adsorption effect between the accommodation groove and the pressing cover, multiple transformers are firmly clamped to avoid the dropping and displacement of the transformers. The accommodation groove can restrict the transformers so that the formed transformer array is neatly arranged. The pressing cover can fix the transformer array and only make the pin parts to be welded protrude, which can play a protective role for the transformers.

[0017] The pressing cover 2 includes a pressing rod 21. The pressing rod 21 is arranged parallel to the length direction of the accommodation groove 1. Both ends of the pressing rod 21 are fixedly connected with support blocks 22. The size of the support blocks 22 is adapted to the groove width of the accommodation groove 1. A strong magnet 4 is embedded on the surface of the support block 22 that fits with the groove bottom, and the strong magnet 4 is embedded at the corresponding position on the groove bottom. By the adaptive fit between the support block and the accommodation groove, the distance between the pressing rod and the groove bottom of the accommodation groove is determined to ensure that all transformers can be pressed simultaneously. Through the strong magnets arranged at the corresponding positions, the pressing cover can be quickly attracted to the accommodation groove, improving the clamping efficiency, and the adsorption force generated by the strong magnet can also ensure the firmness of clamping.

[0018] A positioning block 11 is arranged on the groove bottom of the accommodation groove 1. The positioning block 11 abuts against the transformer at the end. When installing the transformer, only need to place the transformer into the groove and slide along the groove to abut against the positioning block. The subsequent placed transformers slide in turn to abut against the previous transformer, so as to position multiple transformers in turn. There are two positioning blocks 11. The distance between the adjacent end faces of the two positioning blocks 11 is an integer multiple of the width dimension of the transformer, ensuring that after the space between the two positioning blocks is filled with transformers, the transformers at both ends of the array can respectively abut against the two positioning blocks. The two positioning blocks 11 respectively fit with the inner side surfaces of the two support blocks 22, which can play a guiding role in the pressing process of the pressing cover, making the position of the pressing cover more accurate after pressing, and avoiding the influence of the pressing process on the position of the transformer. Especially when the number of transformers in a single batch is not enough to fill the space between the two positioning blocks, before the pressing cover is fully pressed, it does not contact the transformer and will not cause the displacement of the transformer.

[0019] A soft elastic body 5 is arranged on the surface of the pressing rod 21 close to the accommodation groove 1. The soft elastic body 5 is strip-shaped and arranged along the length direction of the pressing rod 21. The soft elastic body can adopt a sponge strip made of EVA material, which can isolate the pressing rod from the transformer coil and avoid direct contact between the metal pressing rod and the wire package to cause damage. In addition, its elasticity can be adjusted according to the size of the wire package error.

[0020] The pressure bar 21 correspondingly presses against the middle part of the transformer. Soft shielding bodies 23 are arranged on both sides of the pressure bar 21, and the shielding bodies 23 are made of heat-insulating materials. The shielding bodies can adopt high-silica self-adhesive tapes, which have the effect of fire prevention and flame retardancy, effectively isolate the heat during welding and the splashing of solder balls, play a good protective role for the transformer, and the self-adhesive tapes can be directly adhered to the metal frame composed of the support blocks and the pressure bar. As consumables, they are convenient to replace and use.

[0021] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
