Description

Technical Field

[0001] This utility model relates to the technical field of transformer copper strip processing equipment, and specifically to transformer copper strip processing equipment. Background Technology

[0002] Copper strip processing is a crucial part of transformer production. Welding mainly involves welding the copper strip wrapped around the outer surface of the transformer to the leads. Whether the copper strip weld is firm is an important indicator of whether the transformer is up to standard.

[0003] In the current process of welding copper strips for small transformers, the transformer is usually fixed by manually pushing the clamping parts with one hand or by directly gripping the transformer. During welding, another hand is needed to hold tweezers or other pressing tools to press and abut the copper strip welding end to ensure that the two ends of the copper strip wrapped around the outer surface of the transformer and the transformer leads can be welded in a stable superposition. However, this manual clamping and abutting welding method is not only inefficient, but also prone to welding defects due to incomplete abutment as the worker's fatigue increases.

[0004] Existing methods for welding copper strips in transformers require manual handling, where each transformer is individually clamped and the copper strip is brought into contact with a welding torch for welding. This method is not only inefficient, but the manual contact can also lead to incomplete contact and substandard welds. Therefore, we propose a transformer copper strip processing device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings mentioned in the background art and provide a transformer copper strip processing device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] Transformer copper strip processing equipment, including:

[0008] A processing plate mounted on an external workbench, the processing plate having multiple slots for placing transformers;

[0009] A clamping mechanism is mounted on a processing plate. The clamping mechanism includes a first clamping block and a second clamping block for clamping a transformer, and an electric push rod for driving the first clamping block to move towards the second clamping block for clamping.

[0010] The abutting mechanism is disposed on the second clamping block. The abutting mechanism includes an abutting block for abutting the transformer copper strip, a first spring for abutting the auxiliary abutting block for abutting copper strips of different thicknesses, and a fixing block for pushing the abutting block to the copper strip welding point.

[0011] Optionally, the clamping mechanism further includes a connecting frame slidably connected to the surface of the processing plate, the connecting frame being fixedly connected to a plurality of first clamping blocks, and one end of each first clamping block being fixedly connected to the output shaft of an electric push rod.

[0012] Optionally, the abutting mechanism further includes a sliding groove on the top of the second clamping block, a limiting slider is slidably connected in the sliding groove, and the top of the limiting slider is fixedly connected to the fixing block. The bottom of the fixing block near the first clamping block has a slot, and the inner wall of the slot is slidably connected to the abutting block. The abutting block and the top of the inner wall of the slot are fixedly connected to a first spring. The fixing block is made of magnetic material, and a magnetic block with opposite magnetic poles to the second clamping block is fixedly connected to the top of the first clamping block.

[0013] Optionally, a limiting shaft is fixedly connected to the top of the abutment block, and the top end of the limiting shaft penetrates the top of the inner wall of the slot and is fixedly connected to a stop block.

[0014] Optionally, a pressure sensor is fixedly connected to the inner wall of the slide, and a second spring is fixedly connected between the limiting slider and the inner wall of the pressure sensor. An induction lamp is fixedly installed on the second clamping block, and both the induction lamp and the pressure sensor are electrically connected to an external controller.

[0015] Optionally, one end of the abutment block relative to the first clamping block is set as an inclined surface, and the ends of the fixing block and the abutment block relative to the first clamping block are provided with arc-shaped grooves adapted to the welding gun head.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When in use, this transformer copper strip processing device activates an electric push rod, which drives the first clamping block within the clamping mechanism to simultaneously clamp multiple transformers. As the first clamping block clamps the transformers and moves them to a designated position, it triggers a fixing block within the abutment mechanism to abut the copper strip welding end. The elasticity of the first spring further enhances the stability of the copper strip clamping process. This process solves the problems of low processing efficiency and poor welding results associated with traditional methods where manual handling is required—one hand to clamp the transformer, the other to abut the copper strip welding end with a tool, and then welding with a welding gun. Firstly, it significantly improves the welding efficiency of the transformer surface copper strip. Secondly, the stable abutment method avoids poor welding quality during copper strip welding, thus increasing the product qualification rate. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The present invention details the above technical solution through the following embodiments:

[0029] Example 1

[0030] Please see Figures 1-6 As shown, the transformer copper strip processing device includes:

[0031] The processing plate 1 is installed on an external workbench, and the processing plate 1 has multiple placement slots 2 for placing transformers.

[0032] The clamping mechanism 3 is mounted on the processing plate 1. The clamping mechanism 3 includes a first clamping block 33 and a second clamping block 35 for clamping the transformer, and an electric push rod 31 for driving the first clamping block 33 to move towards the second clamping block 35 for clamping.

[0033] The abutting mechanism 4 is mounted on the second clamping block 35. The abutting mechanism 4 includes an abutting block 441 for abutting the transformer copper strip, a first spring 442 for abutting copper strips of different thicknesses with the auxiliary abutting block 441, and a fixing block 43 for pushing the abutting block 441 to the copper strip welding point.

[0034] When using this processing device, the processing plate 1 is first installed on the external workbench and positioned to correspond to the welding gun. This ensures that the multiple placement slots 2 on the processing plate 1 can be matched with the corresponding welding gun positions. During welding, the electric push rod 31 is activated, causing the electric push rod 31 in the clamping mechanism 3 to drive the first clamping block 33 to clamp multiple transformers simultaneously. As the first clamping block 33 clamps the transformers and moves them to the designated position, it triggers the fixing block 43 in the abutment mechanism 4 to drive the abutment block 441 to abut and clamp the copper strip welding end. The stability of the copper strip clamping is further enhanced by the elasticity of the first spring 442. This process solves the problems of low processing efficiency and poor welding effect caused by the traditional method of manually clamping the transformer with one hand and using a tool to abut the copper strip welding end with the other hand in conjunction with the welding gun for welding. Firstly, it greatly improves the welding processing efficiency of the copper strip on the transformer surface. Secondly, the stable abutment method can avoid the problem of poor welding quality when welding the copper strip, thus improving the product qualification rate.

[0035] Furthermore, the clamping mechanism 3 also includes a connecting frame 32 that is slidably connected to the upper surface of the processing plate 1. The connecting frame 32 is fixedly connected to a plurality of first clamping blocks 33 respectively, and one end of the first clamping block 33 is fixedly connected to the output shaft of the electric push rod 31.

[0036] By activating the electric push rod 31, its output shaft will drive multiple first clamping blocks 33 fixedly connected to it to move in the same direction, achieving the effect of simultaneously clamping multiple transformers. With the help of multiple welding guns, multiple transformer copper strips can be welded at the same time, greatly improving processing efficiency and reducing manual labor intensity.

[0037] Furthermore, the abutment mechanism 4 also includes a groove 41 formed on the top of the second clamping block 35. A limiting slider 42 is slidably connected in the groove 41, and the top of the limiting slider 42 is fixedly connected to the fixing block 43. A slot 44 is formed at the bottom of one end of the fixing block 43 near the first clamping block 33, and the inner wall of the slot 44 is slidably connected to the abutment block 441. The top of the inner wall of the abutment block 441 and the slot 44 are fixedly connected together with a first spring 442. The fixing block 43 is made of magnetic material, and a magnetic block 34 with the opposite magnetic pole to that of the second clamping block 35 is fixedly connected to the top of the first clamping block 33.

[0038] When the first clamping block 33 is moved closer to the second clamping block 35 by the connecting frame 32, the magnetic block 34 fixedly connected to its top will generate a magnetic attraction force through its characteristic of having opposite magnetic poles to the fixed block 43, attracting the fixed block 43 to move closer to it. At this time, the abutment block 441 of the fixed block 43 near the copper strip end of the transformer will gradually come into contact with and abut the copper strip downward. During this process, due to the influence of the thickness of the copper strip itself, the abutment block 441 will move upward to a certain range in order to continuously and stably abut the copper strip and squeeze the first spring 442 to compress and deform. The elastic force generated by the compression and deformation of the first spring 442 makes the abutment block 441 further abut the welding end of the copper strip, ensuring that the copper strip remains continuously stable during welding.

[0039] Example 2

[0040] Further additions are made based on Example 1; please refer to [link / reference]. Figures 5-6 As shown, a pressure sensor 46 is fixedly connected to the inner wall of the slide 41, and a second spring 45 is fixedly connected between the limit slider 42 and the inner wall of the pressure sensor 46. An induction lamp 47 is fixedly installed on the second clamping block 35, and both the induction lamp 47 and the pressure sensor 46 are electrically connected to an external controller.

[0041] With the above settings, when the limit slider 42 moves toward the first clamping block 33, it will compress the second spring 45, thereby continuously applying pressure to the pressure sensor 46. If the pressure value is within the normal preset range, the sensor light 47 will not light up. Conversely, when the second spring 45 experiences metal fatigue during long-term use, the elastic force of the second spring 45 when it is compressed and reset will deviate from the pressure applied to the pressure sensor 46 within the normal range. The pressure sensor 46 will then transmit this pressure signal to the external controller, which will control the sensor light 47 to light up. At this time, the staff can know that the second spring 45 has a problem, so that it can be replaced in time and the continuous use of the device can be guaranteed.

[0042] Example 3

[0043] Further improvements were made based on Example 1; please refer to [link / reference]. Figure 4As shown, further, the top of the abutment block 441 is fixedly connected to a limiting shaft 443, the top of the limiting shaft 443 penetrates the top of the inner wall of the slot 44, and is fixedly connected to a stop block 444.

[0044] By setting the limiting shaft 443, it is possible to ensure that the abutting block 441 will not shift laterally during the compression deformation of the first spring 442 when it abuts against the top of the transformer copper strip, thus preventing a reduction in the abutting effect. This allows the abutting block 441 to move up and down stably. The setting of the stop block 444 can prevent the limiting shaft 443 from disengaging from the through hole of the slot 44, thus preventing the limiting effect of the stop block 444 from failing.

[0045] The abutment block 441 has an inclined surface at one end relative to the first clamping block 33, and the fixing block 43 and the abutment block 441 have an arc-shaped groove at one end relative to the first clamping block 33 that is adapted to the welding gun head.

[0046] With the above settings, when the abutment block 441 moves to the copper strip welding point of the transformer, the inclined bottom of the abutment block 441 can move smoothly to the top of the copper strip without abrading the surface of the copper strip, thus improving the safety of the enhancement device. The arc-shaped groove opened at one end of the fixing block 43 and the abutment block 441 relative to the first clamping block 33 can maximize the contact area of ​​the abutment block 441 with the welding point without affecting the welding, thereby improving the stability of the abutment.

[0047] The working principle of the transformer copper strip processing device in this embodiment is as follows: First, the processing plate 1 is installed on the external workbench and corresponding to the welding gun. This ensures that the multiple placement slots 2 opened on the processing plate 1 can be adapted to the corresponding welding gun positions. During welding, the electric push rod 31 is activated first, causing the electric push rod 31 in the clamping mechanism 3 to drive the first clamping block 33 to clamp multiple transformers simultaneously. During the process of the first clamping block 33 clamping the transformers and moving them to the designated position, the fixing block 43 in the abutment mechanism 4 is triggered, which drives the abutment block 441 to abut and clamp the copper strip welding end. Under the elasticity of the first spring 442, the stability of the copper strip clamping is further improved. The above process solves the problems of low processing efficiency and poor welding effect caused by the traditional method of manually clamping the transformer with one hand and using a tool to abut the copper strip welding end with the other hand in conjunction with the welding gun for welding. After the electric push rod 31 is activated, its output shaft will drive the fixed connection to it. Multiple first clamping blocks 33 move in the same direction to achieve the effect of simultaneously clamping multiple transformers. With the help of multiple corresponding welding guns, multiple transformer copper strips can be welded at the same time, which greatly improves processing efficiency and reduces manual labor intensity. When the first clamping block 33 is driven by the connecting frame 32 to approach the second clamping block 35, the magnetic block 34 fixedly connected to its top will generate magnetic attraction force through its characteristic of opposite magnetic poles to the fixed block 43, attracting the fixed block 43 to approach it. At this time, the abutment block 441 of the fixed block 43 near the end of the transformer copper strip will gradually come into contact with and abut the copper strip downward. During this process, due to the influence of the thickness of the copper strip itself, the abutment block 441 will move upward to a certain range in order to continuously and stably abut the copper strip and squeeze the first spring 442 for compression deformation. The elastic force generated by the compression deformation of the first spring 442 makes the abutment block 441 further abut the welding end of the copper strip, ensuring that the copper strip remains stable during welding.

[0048] Furthermore, when the limiting slider 42 moves towards the first clamping block 33, it compresses the second spring 45, thereby continuously applying pressure to the pressure sensor 46. If the pressure value is within the normal preset range, the sensor light 47 will not light up. Conversely, when the second spring 45 experiences metal fatigue during long-term use, the elastic force of the second spring 45 when it is compressed and reset will deviate from the pressure applied to the pressure sensor 46 within the normal range. The pressure sensor 46 will then transmit this pressure signal to the external controller, which will control the sensor light 47 to light up. At this time, the staff can know that the second spring 45 has a problem, so that it can be replaced in time and the continuous use of the device can be guaranteed.
