Description

Technical Field

[0001] This utility model relates to the technical field of transformer production tinning equipment, and in particular to a transformer pin tinning device. Background Technology

[0002] Transformer pin tinning refers to immersing the metal pins of a transformer into molten solder to form a uniform tin layer on their surface. This prevents pin oxidation, ensures reliable solder joints during subsequent PCB soldering, and reduces contact resistance, signal loss, and corrosion of copper pins, thereby improving product durability.

[0003] Traditional tinning operations are manual, which is not only inefficient but also makes it difficult to guarantee the quality of the finished product. To meet market demand, automated tinning equipment has emerged. For example, Chinese utility model patent CN216632919U discloses a device for tinning network transformers. This tinning device is equipped with a tin bath, and a bracket for mounting a lifting cylinder is set on one side of the top of the tin bath. A transformer clamping mechanism is set at the bottom of the lifting cylinder. The clamping mechanism clamps and fixes the transformer to be tinned, and then the lifting cylinder drives the transformer to move vertically downward until the transformer leads are immersed in the molten tin in the tin bath. The method of moving the transformer leads downward to dip them in molten tin by the lifting cylinder can better control the degree of tinning, making the leads of the tinned transformers consistent across batches.

[0004] The above-mentioned tin-immersion device has the following problems in its operation method of vertically immersing the transformer pins into the molten tin by using a lifting cylinder: when vertically immersed, the molten tin may form a tin bridge between adjacent pins due to surface tension, resulting in a short circuit. In addition, vertical immersion is prone to adsorbing too much tin due to capillary action, forming tin nodules, which affects subsequent installation and thus results in poor product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transformer pin tinning device, which solves the problem that vertical immersion of transformer pins into molten solder easily leads to poor finished product quality.

[0006] According to an embodiment of this utility model, a transformer pin tinning device includes a base, a support plate, a clamping member, a translating member, a deflecting member, a molten solder tank, and a feeding member. The clamping member is slidably disposed on one side of the support plate and is used to clamp the transformer. The translating member is disposed in the middle of the support plate and is used to drive the clamping member to move horizontally. The deflecting member is disposed on one side of the support plate and is used to make the clamping member rotate clockwise or counterclockwise. The molten solder tanks are arranged in pairs on the top of the base and below the clamping member. The feeding member is located below the clamping member and passes through the middle of the support plate. The feeding member is used for feeding and discharging.

[0007] In the above embodiment, a support plate is vertically set on the base. The clamping member is driven to move horizontally on one side of the support plate by the translation component. During the movement, the clamping member can grab the transformer on the material and send it into different solder baths for immersion. At the same time, during the horizontal translation of the clamping member driven by the translation component, the deflection component can make the translation component drive the clamping member to rotate clockwise or counterclockwise, so that the transformer clamped on the clamping member can be immersed in the solder at a certain angle, thereby ensuring the immersion effect.

[0008] In some embodiments, a strip-shaped sliding hole is provided through the middle of the support plate for slidingly mounting the translation member, and the clamping member is fixedly mounted on one end of the translation member.

[0009] In some embodiments, the clamping member includes a vertically arranged lifting cylinder with its output axis pointing downwards and a clamping plate fixedly installed on the output shaft of the lifting cylinder. A deflecting member is located on one side of the support plate, the molten solder tank is vertically distributed with respect to the lifting cylinder, and a feeding member is located below the clamping plate.

[0010] In some embodiments, the translation component includes a support rod slidably disposed inside a strip-shaped sliding hole and a pair of linear modules fixedly disposed at the end of the support rod opposite to the lifting cylinder. The end of the support rod near the linear module is rotatably disposed with a sliding column slidably connected to the strip-shaped sliding hole. The two linear modules are provided with a moving block fixedly connected to the end of the support rod near the sliding column opposite to the lifting cylinder.

[0011] In some embodiments, the deflector includes a pair of racks fixedly mounted on the top of one side of the strip-shaped sliding hole and a gear fixedly sleeved on the outside of the support rod and meshing with the racks.

[0012] In some embodiments, molten solder baths are arranged in pairs and distributed opposite each other on the top sides of the support plate, and the feeder is located between the two molten solder baths.

[0013] In some embodiments, the feeding component includes a feed belt and a discharge belt that both penetrate the support plate.

[0014] Compared with the prior art, this utility model has the following beneficial effects: by adopting a deflection component to cause the translation component to drive the clamping component to rotate clockwise or counterclockwise during the horizontal clamping of the transformer, it solves the technical problem that the vertical immersion of transformer pins into molten solder in the existing tin-immersion device easily leads to poor product quality, thereby achieving the technical effect of ensuring product quality.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In an exemplary implementation, such as Figures 1-4 As shown, this embodiment provides a transformer pin tinning device, including a base 100, a support plate 200, a clamping member 300, a translating member 400, a deflecting member 500, a tin bath 600, and a feeding member 700. The clamping member 300 is slidably disposed on one side of the support plate 200 and is used to clamp the transformer. The translating member 400 is disposed in the middle of the support plate 200 and is used to drive the clamping member 300 to move horizontally. The deflecting member 500 is disposed on one side of the support plate 200 and is used to make the clamping member 300 rotate clockwise or counterclockwise. The tin bath 600 is arranged in pairs on the top of the base 100 and below the clamping member 300. The feeding member 700 is located below the clamping member 300 and passes through the middle of the support plate 200. The feeding member 700 is used for feeding and discharging.

[0023] In this embodiment, a support plate 200 is vertically mounted on the base 100. A translation member 400 drives a clamping member 300 to move horizontally on one side of the support plate 200. During the movement, the clamping member 300 can grab the transformer on the material part 700 and send it into different tin baths 600 for tinning. At the same time, during the horizontal translation of the clamping member 300 driven by the translation member 400, the deflection member 500 can make the translation member 400 drive the clamping member 300 to rotate clockwise or counterclockwise, so that the transformer clamped on the clamping member 300 can be immersed in the tin at a certain angle, thereby ensuring the tinning effect.

[0024] In one embodiment, please refer to Figures 1-3 A strip-shaped sliding hole 210 for sliding installation of translation component 400 is provided through the middle of the support plate 200, and the clamping component 300 is fixedly installed on one end of the translation component 400.

[0025] In this embodiment, one end of the translation member 400 is slidably connected to the support plate 200, and the other end extends a certain length and is used to fix and install the clamping member 300.

[0026] In one embodiment, please refer to Figures 1-3 The clamping component 300 includes a vertically arranged lifting cylinder 310 with its output axis pointing downwards and a clamping plate 320 fixedly installed on the output shaft of the lifting cylinder 310. The deflecting component 500 is located on one side of the support plate 200. The molten solder tank 600 is vertically distributed with the lifting cylinder 310. The feeding component 700 is located below the clamping plate 320.

[0027] In this embodiment, the lifting cylinder 310 is vertically mounted on one end of the translation component 400, and the clamping plate 320 is set on the bottom end of the lifting cylinder 310. The lifting cylinder 310 controls the up and down movement of the clamping plate 320 after picking up the material.

[0028] Among them, the clamping plate 320 is the material handling mechanism in the existing tin dipping device, which can be adapted to meet the actual operation requirements. Specific details will not be elaborated.

[0029] In one embodiment, please refer to Figures 1-4 The translation component 400 includes a support rod 410 slidably disposed inside the strip-shaped sliding hole 210 and a pair of linear modules 420 fixedly disposed at one end of the support rod 410 opposite to the lifting cylinder 310. The end of the support rod 410 near the linear module 420 is rotatably disposed with a sliding column 430 that is slidably connected to the strip-shaped sliding hole 210. The two linear modules 420 are provided with a moving block 440 fixedly connected to the end of the support rod 410 near the sliding column 430 opposite to the lifting cylinder 310.

[0030] In this embodiment, the linear module 420 drives the lifting cylinder 310 to move horizontally. Specifically, the linear module 420 is disposed on one side of the strip-shaped sliding hole 210 of the support plate 200. The two linear modules 420 can drive the moving block 440 to move horizontally. The moving block 440 can then drive the support rod 410 to move horizontally together through the sliding column 430. At the same time, the support rod 410 is rotatably connected to the sliding column 430. Therefore, under the restriction of the deflection member 500, the support rod 410 can drive the lifting cylinder 310 and its upper clamping plate 320 to deflect clockwise or counterclockwise.

[0031] The rotating connection between the support rod 410 and the sliding column 430 has a certain damping to prevent the support rod 410 from easily rotating.

[0032] In one embodiment, please refer to Figures 1-3 The deflector 500 includes a pair of racks 510 fixedly installed on the top of one side of the strip-shaped sliding hole 210 and a gear 520 fixedly sleeved on the outside of the support rod 410 and meshing with the racks 510.

[0033] In this embodiment, when the support rod 410 moves horizontally, it drives the gear 520 to mesh with two oppositely arranged racks 510 respectively. When the gears 520 mesh, they can drive the support rod 410 to rotate, thereby achieving clockwise or counterclockwise deflection.

[0034] In one embodiment, please refer to Figures 1-3 The molten tin baths 600 are arranged in pairs and distributed on opposite sides of the top of the support plate 200, and the feed component 700 is located between the two molten tin baths 600.

[0035] In this embodiment, the tin bath 600 is set up separately to facilitate the immersion of the leads on both sides of the transformer.

[0036] Furthermore, a scraper 610 is provided on the top of the tin bath 600, and the scraper 610 is driven by an electric telescopic rod 620 to scrape away impurities generated during tin immersion.

[0037] The feeding component 700 includes a feeding belt 710 and a discharging belt 720 that both penetrate the support plate 200. Both the feeding belt 710 and the discharging belt 720 are existing structures that enable material feeding and unloading, and will not be described in detail.

[0038] To better understand this utility model, the following is combined with... Figures 1 to 4The technical solution of this utility model is described in detail as follows: In use, the transformer material to be tinned is transported to the bottom of the clamping plate 320 by the feeding belt 710. The clamping plate 320 is controlled by the lifting cylinder 310 to grip the transformer material. Then, the linear module 420 is driven to move the sliding column 430 in the strip-shaped sliding hole 210 of the support plate 200 through the moving block 440. At the same time, the sliding column 430 can drive the lifting cylinder 310 to move horizontally together through the support rod 410. During the horizontal movement of the two, the gear 520 on the outside of the support rod 410 meshes with two oppositely arranged racks 510. The meshing of the gears 520 can drive the support rod 410 to rotate, thereby achieving clockwise or counterclockwise deflection. This allows the transformer pins clamped on the clamping plate 320 to be immersed in the molten solder at a certain angle, thus ensuring the tinning effect.

[0039] In summary, this utility model solves the technical problem in existing tinning devices where vertical immersion of transformer pins into molten solder easily leads to poor finished product quality by using a deflector 500 to cause the translation 400 to drive the clamping 300 to rotate clockwise or counterclockwise during the horizontal clamping of the transformer. This achieves the technical effect of ensuring finished product quality.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
