Description

Technical Field

[0001] The utility model relates to the technical field of electronic component welding, in particular to a welding device for an SMD patch transformer. Background Art

[0002] SMD chip transformer is a surface mount transformer, usually used in electronic equipment, for power conversion, signal transmission, etc. It is characterized by small size, light weight, high efficiency and good reliability.

[0003] Most of the existing SMD patch transformer welding devices are composed of a clamping component and a welding component. Before use, the SMD patch transformer to be processed is clamped and fixed by the clamping component, and then the welding component is used to quickly weld it mechanically. For example, the Chinese patent with the publication number CN219725018U and the name: A welding device for transformer processing, that is, when the part is transported to the position of the clamping component, the first telescopic rods on both sides will move the shell toward the part, and then the clamping rods in the shell will fix the part between the clamping rods on both sides. If the part needs to be rotated, it only needs to be rotated by the rotating member. This device increases the welding efficiency of the part. However, since most of the existing SMD patch transformers are small sizes such as 0.5mm and 0.8mm, when the clamping component clamps it, it is often possible to be clamped unsteadily or offset, so that the SMD patch transformer will be in a tilted state during welding, thereby affecting the accuracy of the overall welding. Therefore, the present application provides a SMD patch transformer welding device to meet the demand. Utility Model Content

[0004] The purpose of the present application is to provide a welding device for an SMD patch transformer, which solves the problem of unstable clamping of the SMD patch transformer during welding in the prior art and achieves the purpose of improving welding accuracy and stability.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a welding device for SMD patch transformers, comprising a welding workbench, a mounting bracket and a welding body fixedly connected to the top of the welding workbench, the welding workbench is fixedly connected to a first storage box, a second storage box and a receiving pad, and the receiving pad is located between the first storage box and the second storage box, and two electric slide rails are used to drive the mounting bracket to move horizontally linearly on the top of the welding workbench, and two adjacent mounting brackets are provided with adjustment cavities on opposite sides, and the interior of the adjustment cavity is connected to the same driving member through two electric push rods, two connecting shafts are arranged between the two driving members, and a coating roller brush is sleeved on the connecting shaft, and the two connecting shafts can be lifted and lowered between the two mounting brackets through the top of the first storage box and the second storage box.

[0006] Preferably, two lower grooves are formed on the top of the welding workbench body, and the electric slide rail is fixedly connected inside the lower grooves, and the top of the welding workbench body and the electric slide rail are located in the same plane.

[0007] Preferably, two drainage pieces are fixedly connected to the top of the welding workbench body, and opposite sides of the two drainage pieces are fixedly connected to two sides of the receiving pad respectively, and the height of the drainage piece is lower than the height of the receiving pad.

[0008] Preferably, an inclined section is provided on the top of the guide member, and the angle between the inclined section and the welding workbench body is thirty-five degrees, and the other side wall of the guide member is connected to the top of the first storage box body or the second storage box body.

[0009] Preferably, two installation openings are opened on the top of the welding workbench, and the first storage box and the second storage box are respectively fixedly connected inside the two installation openings, and the tops of the first storage box and the second storage box are both located in the same plane as the top of the welding workbench.

[0010] Preferably, the size of the driving member is adapted to the size of the regulating cavity, and chamfered grooves are provided at four corners of the driving member.

[0011] Preferably, the welding body is an inverted concave structure, and the welding workbench body and the welding body are located on the same longitudinal axis, and the receiving welding pad is located below the welding body.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. The utility model has a reasonable structure. By providing a coating roller brush and a first storage box, the four coating roller brushes will be immersed in the inside of the flux respectively before use. At this time, the coating roller brushes will absorb the flux and the cleaning agent to a certain extent under the action of their own structure, and the electric slide rail and the electric push rod can be controlled by an external controller, so that the electric push rod drives the two coating roller brushes immersed in the flux to move longitudinally. When they move to a suitable position, the electric slide rail will drive the coating roller brush to move horizontally through the mounting bracket. When the coating roller brush moves to the receiving pad, the coating roller brush will contact the top of the receiving pad, so that the flux absorbed by itself is coated on the top of the receiving pad. At this time, the SMD patch transformer to be processed can be directly placed on the top of the receiving pad, and then the welding body is turned on to directly weld it. At this time, the coated flux will directly increase the adhesion of the welding and improve the overall welding effect.

[0014] 2. In the utility model, by providing a drainage piece, when the coating roller brush is forced to move horizontally, the material attached to the coating roller brush can effectively drip onto the drainage piece and flow back to the inside of the first storage box or the second storage box along the inclined section at the top of the drainage piece, and then be collected, so as to achieve the effect of reuse, and at the same time, it also prevents the material from dripping onto the top of the welding workbench and affecting the cleanliness of the overall operating table.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0027] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0028] It includes a welding workbench body 1, a mounting bracket 3 and a welding body 15 fixedly connected to the top of the welding workbench body 1, a first storage box body 10, a second storage box body 11 and a receiving pad 12 are fixedly connected to the welding workbench body 1, and the receiving pad 12 is located between the first storage box body 10 and the second storage box body 11, and two electric slide rails 2 are used to drive the mounting bracket 3 to move horizontally linearly on the top of the welding workbench body 1, and an adjustment cavity 4 is opened on the opposite side of two adjacent mounting brackets 3, and the interior of the adjustment cavity 4 is connected to the same driving member 6 through two electric push rods 5, two connecting shafts 7 are arranged between the two driving members 6, and a coating roller brush 8 is sleeved on the connecting shaft 7, and the two connecting shafts 7 can be lifted and moved between the two mounting brackets 3 through the top of the first storage box body 10 and the second storage box body 11.

[0029] Before using it, the welding workbench 1 can be directly placed on a flat surface, and then the flux and the cleaning agent are poured into the first storage box 10 and the second storage box 11 respectively, so that the four coating roller brushes 8 will be immersed in the inside of the flux and the cleaning agent respectively. At this time, the structure of the coating roller brush 8 itself will absorb the flux and the cleaning agent to a certain extent. At this time, the electric slide rail 2 and the electric push rod 5 can be directly controlled by the external controller, so that two of the electric push rods 5 drive the two coating roller brushes 8 immersed in the flux to move longitudinally. When it reaches a suitable position, the electric slide rail 2 will drive the coating roller brush 8 to move horizontally through the mounting bracket 3. When the coating roller brush 8 moves to the receiving pad 12, the coating roller brush 8 will contact the top of the receiving pad 12, thereby coating the flux absorbed by itself on the top of the receiving pad 12. At this time, the SMD patch transformer to be processed can be directly placed on the top of the receiving pad 12, and then the welding body 15 is turned on to directly weld it. At this time, the coated flux will directly increase the adhesion of the welding and improve the overall welding effect.

[0030] After the welding is completed, the SMD patch transformer can be directly removed. At this time, the coating roller brush 8 with the detergent attached can be driven by the electric push rod 5 to move longitudinally. When it moves to a suitable position, the electric slide rail 2 will drive the coating roller brush 8 to move horizontally through the mounting bracket 3. When the coating roller brush 8 moves to the receiving pad 12, the coating roller brush 8 will contact the top of the receiving pad 12, thereby coating the detergent absorbed by itself on the top of the receiving pad 12, and then cleaning the top of the receiving pad 12 to ensure its subsequent normal use.

[0031] Two lower grooves 14 are formed on the top of the welding workbench body 1, and the electric slide rail 2 is fixedly connected inside the lower grooves 14, and the tops of the welding workbench body 1 and the electric slide rail 2 are located in the same plane.

[0032] The setting at the same height can effectively provide space for the movement of the adjustment cavity 4 and the coating roller brush 8, so that when the coating roller brush 8 moves to contact the receiving pad 12, the receiving pad 12 will exert a certain extrusion force on the coating roller brush 8, thereby ensuring the overall coating effect.

[0033] Two drainage members 13 are fixedly connected to the top of the welding workbench body 1 , and opposite sides of the two drainage members 13 are fixedly connected to the two sides of the receiving pad 12 , respectively. The height of the drainage members 13 is lower than that of the receiving pad 12 .

[0034] The height setting of the guide member 13 can effectively allow the coating roller brush 8 to touch the side wall of the receiving pad 12 when it moves. The side wall of the receiving pad 12 will apply a certain pressure to the coating roller brush 8, and then when the coating roller brush 8 moves horizontally, the pressure between the coating roller brush 8 and the top of the receiving pad 12 will always remain the same, so that the material on the surface of the coating roller brush 8 can be evenly coated on the top of the receiving pad 12, thereby improving its overall coating effect.

[0035] The top of the flow guide 13 is provided with an inclined section, and the angle between the inclined section and the welding workbench body 1 is thirty-five degrees. The other side wall of the flow guide 13 is connected to the top of the first storage box 10 or the second storage box 11.

[0036] The setting of the guide member 13 can effectively receive the flux or cleaning agent attached to the coating roller brush 8, so that when the coating roller brush 8 is forced to move horizontally, the material attached to the coating roller brush 8 can effectively drip onto the guide member 13, and flow back to the first storage box 10 or the second storage box 11 along the inclined section at the top of the guide member 13, and then be collected, so as to achieve the effect of reuse, and at the same time, it also prevents the material from dripping on the top of the welding workbench 1, affecting the cleanliness of the overall operating table.

[0037] Two installation openings 9 are opened on the top of the welding workbench body 1, and the first storage box 10 and the second storage box 11 are fixedly connected inside the two installation openings 9 respectively, and the tops of the first storage box 10 and the second storage box 11 are both located in the same plane as the top of the welding workbench body 1.

[0038] The setting of the mounting port 9 can effectively provide effective space for the installation of the first storage box 10 and the second storage box 11, so that the top of the first storage box 10 and the second storage box 11 will be at the same height as the top of the welding workbench 1. At this time, when it is in use, the coating roller brush 8 immersed in the first storage box 10 or the second storage box 11 will be more convenient to move or adjust.

[0039] The size of the driving member 6 is matched with the size of the adjusting cavity 4 , and chamfered grooves are provided at the four corners of the driving member 6 .

[0040] The matching sizes of the adjusting cavity 4 and the driving member 6 can effectively allow the driving member 6 to slide along the adjusting cavity 4 under the action of the electric push rod 5, and then effectively drive the connecting shaft 7 to change the position height of the connecting shaft 7 and the coating roller brush 8. Before its use, the driving member 6 will slide to the maximum displacement at the bottom, so that the driving member 6 can directly fall off the adjusting cavity 4 and slide into the first storage box 10 or the second storage box 11. At this time, if it is needed to be used, it is only necessary to control the driving member 6 to rise through the electric push rod 5, and then let the driving member 6 slide into the interior of the adjusting cavity 4. At this time, the chamfered design of the driving member 6 can effectively increase the stability of the driving member 6 when it enters the adjusting cavity 4 for docking, making it more convenient as a whole.

[0041] The welding body 15 is an inverted concave structure, and the welding workbench body 1 and the welding body 15 are located on the same longitudinal axis, and the receiving pad 12 is located below the welding body 15 .

[0042] During its use, the SMD patch transformer to be soldered can be directly placed on the receiving pad 12, and the soldering head of the soldering body 15 will be placed on the top of the SMD patch transformer, thereby making the overall soldering operation more convenient.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
