Description

Technical Field

[0001] This utility model belongs to the field of inductor adhesive application, and specifically relates to an inductor adhesive application device. Background Technology

[0002] An inductor bonding machine is a device used to apply adhesive during the manufacturing process of inductors. This equipment is primarily used to apply adhesive to the coils and fins of inductors to prevent paint contamination and improve product reliability and performance. To improve production efficiency and bonding quality, modern inductor bonding machines typically employ automation technologies, such as automatic dispensing arms. This method requires the adhesive to cure quickly, withstand high temperatures, and have high bonding strength to ensure that components do not detach during high-temperature soldering.

[0003] Chinese Patent No. CN221125709U discloses an inductor adhesive application mechanism, comprising: a fixing plate; a guide groove connected to one side of the fixing plate; a first adhesive application device located below the guide groove, the first adhesive application device being used to apply adhesive to the lower side of the two fins of the inductor and to transport the inductor along the length direction of the guide groove; and a second adhesive application device located below the guide groove, the second adhesive application device being used to apply adhesive to the upper side of the two fins of the inductor. By setting up the guide groove and cooperating with the first and second adhesive application devices, the two fins of the inductor can be adhered with tape, avoiding contamination of the fins during subsequent painting processes. Compared with traditional manual adhesive application processes, the adhesive application process is fully automated, saving time and labor, and greatly improving adhesive application efficiency. As can be seen from the above structure, by setting the guide groove, the first adhesive application device and the second adhesive application device in combination, the two fins of the inductor can be attached with adhesive tape, avoiding contamination of the fins in the subsequent painting process. Compared with the traditional manual adhesive application process, the adhesive application process is fully automated, saving time and labor, and greatly improving the adhesive application efficiency. However, the pressure roller structure of the above device cannot be flexibly adjusted, which may result in ineffective pressing when the pressure roller presses the tape of different thicknesses. This is because the position of the pressure roller cannot cover the plate, which may reduce the practicality of the device. Utility Model Content

A lower adhesive application structure is located below the material guide groove on the front of the mounting frame. An upper guide structure is located between the upper adhesive application structure and the material guide groove on the front of the mounting frame. A lower adhesive application assembly and a lower guide structure are located on the front of the mounting frame. A tensioning structure is located on one side of the front of the mounting frame above the material guide groove. The other side of the mounting frame... The upper end of the guide trough is provided with a pressing structure, and both sides of the guide trough are provided with pressing components. The pressing components include mounting vertical plates on both sides of the guide trough. The inner side of each mounting vertical plate is rotatably connected to a mounting crossbar. One end of the mounting crossbar is provided with an adjusting component. The inner side of the adjusting component is provided with a pressure roller. The inner side of the adjusting component is fixedly connected to the inner side of the pressure roller. The lower end of the other end of the mounting crossbar is fixedly connected to a push rod.

[0006] As a preferred technical solution, the adjustment assembly includes an adjustment screw hole on the surface of the mounting crossbar, an adjustment screw is threadedly connected to the inside of the adjustment screw hole, a mounting plate is fixedly connected to the other end of the adjustment screw, the inner side of the mounting plate is fixedly connected to the pressure roller, and a rotating handle is fixedly connected to the outer end of the adjustment screw.

[0007] As a preferred technical solution, the outer side of the mounting plate is inserted into the surface of the mounting crossbar, and a limiting slide rod is fixedly connected to the outer side of the mounting plate. A limiting through hole is opened on the surface of the mounting crossbar, and the limiting through hole is slidably connected to the limiting slide rod.

[0008] As a preferred technical solution, the pressure roller includes a rotating shaft, the inner ring of the rotating shaft is fixedly connected to the mounting plate, the outer ring of the rotating shaft is fixedly connected to a roller body, and the outer surface of the roller body is fixedly connected to a rubber pad, and the surface of the rubber pad is provided with multiple anti-slip grooves.

[0009] As a preferred technical solution, the linkage shaft includes a connecting rod disposed inside the roller body inside the mounting plate, and a central rod is inserted into the other end of each connecting rod, with both ends of the central rod slidably inserted into the connecting rod.

[0010] As a preferred technical solution, the push rod includes a sleeve rod disposed at the lower end of the other end of the mounting crossbar.

[0012] In summary, the present invention has the following main advantages: First, this utility model, through its adjustable component, allows for the adjustment of the distance between the two pressure rollers during use. By twisting the handle, the adjusting screw is rotated. Under the action of the adjusting screw hole, the adjusting screw moves inward or outward, thereby moving the mounting plate and the pressure rollers. This allows for the adjustment of the distance between the two pressure rollers, enabling flexible adjustment of the distance between the pressure rollers when dealing with different types of tape. Secondly, this utility model, through the setting of push rods and limiting holes, allows the pressure roller to press the inductor fins together. As the inductor fins pass through the pressure roller, the pressure roller can be lifted, causing the fins to move at the bottom of the pressure roller. This allows the adhesive tape on the fin surface to be pressed together simultaneously with the movement of the fins. Furthermore, when the pressure roller is lifted by the fins, it will apply upward pressure under the action of a spring, increasing the force at the mounting crossbar pressure roller section. This, in turn, increases the downward force applied by the pressure roller, thereby enhancing the pressing effect of the pressure roller on the fins. This prevents the adhesive tape from separating after the inductor is applied. Attached Figure Description

[0015] Example refer to Figures 1 to 4 The inductor adhesive applicator of this embodiment includes a mounting frame 1. A material guide groove 9 is provided on the front of the mounting frame 1. An upper adhesive application structure 2 is provided at the upper end of the material guide groove 9 on the front of the mounting frame 1. A lower adhesive application structure 3 is provided at the lower end of the material guide groove 9 on the front of the mounting frame 1. An upper guide structure 4 is provided between the upper adhesive application structure 2 and the material guide groove 9 on the front of the mounting frame 1. A lower guide structure 5 is provided between the lower adhesive application assembly and the support of the material guide groove 9 on the front of the mounting frame 1. A tensioning structure 6 is provided at the upper end of the material guide groove 9 on one side of the front of the mounting frame 1. A pressing structure 8 is provided at the upper end of the material guide groove 9 on the other side of the mounting frame 1. A pressing assembly 7 is provided on both sides of the material guide groove 9. The pressing assembly 7 includes components disposed on the material guide groove 9. The vertical mounting plates 71 on both sides of the groove 9 are rotatably connected to the inner side of the vertical mounting plates 71. An adjustment component 75 is provided at one end of the horizontal mounting plate 72. A pressure roller 76 is provided inside the adjustment component 75. A linkage shaft 77 is fixedly connected to the inner side of the adjustment component 75 and the inner side of the pressure roller 76. A push rod 73 is fixedly connected to the lower end of the other end of the horizontal mounting plate 72. A limit hole 74 is opened at the upper end of the guide groove 9. The limit hole 74 and the limit push rod 73 are inserted into each other. Fixed screw holes are opened on both sides of the guide groove 9. Fixed through holes 12 are opened on both sides of the surface of the vertical mounting plate 71. A fixed screw 13 is inserted into the inside of the fixed through hole 12. The fixed screw 13 passes through the fixed through hole 12 and is threadedly connected to the fixed screw hole.

[0016] refer to Figure 2 and Figure 3The adjusting assembly 75 includes an adjusting screw hole 751 on the surface of the mounting crossbar 72. An adjusting screw 752 is threadedly connected to the inside of the adjusting screw hole 751. A mounting plate 754 is fixedly connected to the other end of the adjusting screw 752. The inner side of the mounting plate 754 is fixedly connected to the pressure roller 76. A rotating handle 753 is fixedly connected to the outer end of the adjusting screw 752. By twisting the rotating handle 753, the adjusting screw 752 is driven to rotate. Under the action of the adjusting screw hole 751, the adjusting screw 752 will move inward or outward according to the direction of rotation. Thus, the movement of the adjusting screw 752 drives the mounting plate 754 to move. The movement of the mounting plate 754 drives the pressure roller 76 to move, thereby allowing the distance between the two pressure rollers 76 to be adjusted.

[0017] refer to Figure 2 and Figure 3 The outer side of the mounting plate 754 is inserted into the surface of the mounting crossbar 72. The outer side of the mounting plate 754 is fixedly connected with a limiting slide bar 11. The surface of the mounting crossbar 72 is provided with a limiting through hole 10. The limiting through hole 10 is slidably connected to the limiting slide bar 11. Through the setting of the limiting slide bar 11 and the limiting slide hole, the mounting plate 754 can be limited, so as to avoid the mounting plate 754 from rotating due to the lack of a limiting structure, which would cause the pressure roller 76 to be unstable.

[0018] refer to Figure 2 and Figure 3 The pressure roller 76 includes a rotating shaft 761. The inner ring of the rotating shaft 761 is fixedly connected to the mounting plate 754. The outer ring of the rotating shaft 761 is fixedly connected to a roller body 762. Rubber pads 763 are fixedly connected to the outer surface of the roller body 762. Multiple anti-slip grooves 764 are formed on the surface of the rubber pads 763. The rubber pads 763 provide protection for the tape on the basis of anti-slip, avoiding damage to the fins due to excessive pressure. The anti-slip grooves 764 can achieve an effective anti-slip effect.

[0019] refer to Figure 2 and Figure 3 The linkage shaft 77 includes a connecting rod 772 disposed inside the roller body 762 inside the mounting plate 754. The other end of the connecting rod 772 is inserted into a center rod 771. Both ends of the center rod 771 are slidably inserted into the connecting rod 772. The linkage rod ensures that the positions of the two pressure rollers 76 are the same during use without deviation. At the same time, the connecting rod 772 does not affect the adjustment effect between the pressure rollers 76.

[0020] refer to Figure 2 and Figure 4The push rod 73 includes a sleeve rod 731 located at the lower end of the other end of the mounting crossbar 72. A spring 732 is fixedly connected inside the sleeve rod 731. A contact plate 733 is fixedly connected to the other end of the spring 732. The contact plate 733 is located inside the limiting hole 74 and is movably connected to the limiting hole 74. When the inductor fins pass through the pressure roller 76, the pressure roller 76 can be lifted up, allowing the fins to move at the bottom of the pressure roller 76. This allows the tape on the surface of the fins to be pressed together under the action of the pressure roller 76 while the fins are moving. When the pressure roller 76 is lifted by the fins, it will apply upward pressure under the action of the spring 732, thereby increasing the force at the pressure roller 76 part of the mounting crossbar 72. This will increase the downward force applied by the pressure roller 76, thereby increasing the pressing effect of the pressure roller 76 on the fins.

[0021] Operating principle and advantages: First, install the adhesive tape to the upper adhesive structure 2 and the lower adhesive structure 3 respectively. Then, make contact with the upper guide structure 4 and the lower guide structure 5 respectively. Place the adhesive tape inside the guide groove 9. Move the adhesive tape so that the upper and lower adhesive tapes are bonded at the pressing assembly 7. The inductor can be placed inside the upper guide groove 9 of the lower adhesive tape. Pull the adhesive tape to move the inductor into the pressing assembly 7, so that the upper adhesive tape is also in contact with the inductor fins. When the pressure roller 76 presses the inductor fins, the pressure roller 76 is supported as the inductor fins pass through it, causing the fins to move at the bottom of the pressure roller 76. This allows the adhesive tape on the fin surface to be pressed together under the action of the pressure roller 76 while the fins are moving. When the pressure roller 76 is supported by the fins, it will be subjected to upward pressure under the action of the spring 732. This increases the force on the mounting bar 72 and pressure roller 76, thereby increasing the downward force applied by the pressure roller 76 and enhancing its pressing effect on the fins. When adjusting the distance between the two pressure rollers 76, the adjusting screw 752 is rotated by twisting the rotating handle 753. Under the action of the adjusting screw hole 751, the adjusting screw 752 moves inward or outward, causing the mounting plate 754 to move. The movement of the mounting plate 754 moves the pressure roller 76, allowing for adjustment of the distance between the two pressure rollers 76. The linkage rod ensures that the positions of the two pressure rollers 76 are aligned during use, and the connecting rod 772 does not affect the adjustment effect between the pressure rollers 76.
