Description

Technical Field

[0001] This utility model relates to an auxiliary processing device for inductors, and more particularly to a heating device for adhesive materials used in a lead-joining machine. Background Technology

[0002] Currently, the processing method for inductors involves an inductor lead-connecting machine first applying adhesive to the ends of the leads, then inserting the adhesive-coated leads into the magnetic core, securing them together with the adhesive. Building upon this, existing inductor lead-connecting machines apply adhesive to the leads by first using a transfer wheel to sequentially guide each lead into a pin slot around its perimeter. Then, by rotating the wheel, the ends of each lead slide across the surface of the adhesive-applying wheel. Simultaneously, the surface of the wheel is evenly coated with adhesive by a coating plate, allowing the adhesive to adhere to the ends of the leads during sliding, thus achieving the adhesive application function.

[0003] However, the above-mentioned glue application method has two drawbacks. First, in low-temperature environments during winter, the adhesive on the surface of the glue-applying roller will harden and solidify, resulting in thickness deviations and unevenness of the glue layer on the surface of the glue-applying roller, affecting the glue application effect on the pins. Second, after long-term glue application, a completely cured and non-transferable glue layer will form on the surface of the glue-applying board. As a result, under the condition that the axial position of the glue-applying board and the glue-applying roller remains unchanged, the actual glue thickness on the surface of the glue-applying board after long-term use will be thinner than the preset thickness, further affecting the glue application quality on the pins.

[0004] Therefore, the existing inductor pin bonding machine has a problem with poor bonding stability in its pin application method. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for adhesive application in an inductor connector. This device improves the stability of adhesive application to the leads in the connector.

[0006] The technical solution of this utility model: A glue heating device for a jointing machine, comprising a glue-applying wheel, a transfer wheel on one side of the glue-applying wheel, and a glue-coating plate on the other side of the glue-applying wheel. Adhesive is applied to one side of the glue-coating plate. The glue-coating plate and the glue-applying wheel are arranged perpendicularly to each other, forming a gap for the adhesive to pass through. A mounting plate is provided on one side of the glue-coating plate, and an axial flow fan and a heating wire are respectively connected to both sides of the mounting plate. A mounting block is rotatably connected to the end of the glue-coating plate. The glue-coating plate and the mounting block are connected to each other via a limiting component. The limiting component includes a first toothed plate detachably connected to the mounting block and a second toothed plate fixedly connected to the glue-coating plate. The first toothed plate and the second toothed plate mesh with each other to form a circumferential limiting.

[0007] In the aforementioned heating device for adhesive material in a foot-jointing machine, a number of rectangular inserts are arranged in a ring around the first toothed plate and the second toothed plate, and the first toothed plate and the second toothed plate are interlocked by the rectangular inserts to form a circumferential limit.

[0008] In the aforementioned heating device for adhesive material in a foot-jointing machine, a fixing sleeve is threadedly connected to the middle of the mounting block. One end of the fixing sleeve extends to the outer side of the first toothed plate and fits against the first toothed plate. The fixing sleeve is used to press and fix the first toothed plate after tightening.

[0009] In the aforementioned adhesive heating device for a foot-jointing machine, a threaded hole is formed in the middle of the fixing sleeve, and a fixing screw is slidably connected to the end of the adhesive plate. The end of the fixing screw passes through the second toothed plate and is threadedly connected to the fixing sleeve.

[0010] In the aforementioned heating device for adhesive material in a foot-jointing machine, an elastic element sleeved on the outside of the fixing screw is provided between the fixing sleeve and the second toothed plate.

[0011] Compared with the prior art, this utility model has the following characteristics:

[0012] (1) This utility model uses an axial fan and heating wire on one side of the adhesive plate to heat the air and blow it to the adhesive in the low temperature environment of winter, thereby heating the adhesive and effectively preventing the adhesive from hardening and solidifying due to low temperature, thus improving its application stability.

[0013] (2) By connecting the coating plate and the mounting block with the limiting component, it is convenient to position the coating plate in the early stage. On the other hand, when the axial position of the coating plate needs to be adjusted in the later stage, the tilt angle of the coating plate can be limited by the cooperation of the first tooth plate and the second tooth plate, so as to avoid the coating plate from shifting after adjustment and improve the operation convenience of the operator.

[0014] (3) Through the structural cooperation of the fixed sleeve, the fixed screw and the elastic element, the elastic element can apply an axial outward extrusion force to the coating plate, and the fixed screw overcomes the extrusion force and limits the coating plate axially. On this basis, the operator can adjust the axial position of the coating plate by screwing in or out the fixed screw during operation, and cooperate with the first tooth plate and the second tooth plate to prevent the coating plate from rotating during the transverse movement, thereby improving the adjustment stability of the coating plate. Under the above cooperation, when the thickness of the cured glue layer on the surface of the glue-applying wheel changes, the operator can adjust the axial position of the coating plate to ensure the consistency of the interval distance between the glue-applying wheel and the coating plate, thereby improving the glue application stability of the pin.

[0015] Therefore, this invention can improve the stability of the adhesive application to the pins by the inductor pin connector machine. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example. A heating device for adhesive material in a lead-joining machine, configured as follows: Figure 1 As shown, the device includes a glue-applying roller 1, a transfer roller 2 on one side of the glue-applying roller 1, and a glue-applying plate 3 on the other side. The end of the glue-applying plate 3 is fixedly connected to the lead-jointing frame. Adhesive 4 is applied to one side of the glue-applying plate 3. The glue-applying plate 3 and the glue-applying roller 1 are arranged perpendicularly to each other, forming a gap through which the adhesive 4 passes. A mounting plate 6, detachably connected to the lead-jointing frame, is provided on one side of the glue-applying plate 3. An axial fan 7 and a heating wire 8 are respectively connected to both sides of the mounting plate 6. All components are externally connected to a power source. An axial fan 7 is used to blow air through a heating wire 8 to the adhesive 4, and the heating wire 8 is used to heat the adhesive 4 with air. An installation block 9 is rotatably connected to the end of the coating plate 3, and the coating plate 3 and the installation block 9 are connected to each other via a limiting component. The limiting component includes a first toothed plate 10 detachably connected to the installation block 9 and a second toothed plate 11 fixedly connected to the coating plate 3. The first toothed plate 10 and the second toothed plate 11 mesh with each other to form a circumferential limiting.

[0021] The adhesive plate 3 includes an L-shaped first plate 301 and a thin sheet-shaped second plate 302. The second plate 302 and the first plate 301 are connected to each other by a screw structure. The second plate 302 is provided with an elongated hole for the screw to pass through, so that the operator can adjust the extension length of the second plate 302 according to the needs during the initial installation.

[0022] The first toothed plate 10 and the second toothed plate 11 are surrounded by a number of rectangular inserts 5 in a ring. The first toothed plate 10 and the second toothed plate 11 are interlocked by the rectangular inserts 5 to form a circumferential limit. The rectangular inserts 5 enable the first toothed plate 10 and the second toothed plate 11 to maintain their circumferential limit function when they partially overlap.

[0023] The mounting block 9 is threadedly connected to a fixing sleeve 12 in the middle. One end of the fixing sleeve 12 extends to the outside of the first toothed plate 10 and fits against the first toothed plate 10. The fixing sleeve 12 is used to press and fix the first toothed plate 10 after tightening.

[0024] A threaded hole is formed in the middle of the fixing sleeve 12, and a fixing screw 13 is slidably connected to the end of the adhesive plate 3. The end of the fixing screw 13 passes through the second toothed plate 11 and is threadedly connected to the fixing sleeve 12.

[0025] An elastic element 14 is provided between the fixing sleeve 12 and the second toothed plate 11, which is sleeved outside the fixing screw 13. The elastic element 14 can be a butterfly spring or a wave spring. The elastic element 14 is used to apply an outward compressive force to the second toothed plate 11.

[0026] The middle part of the glue-applying wheel 1 is slidably connected to the motor shaft, and the side wall of the glue-applying wheel 1 is threaded with a set screw that matches the motor shaft. The structural cooperation between the glue-applying wheel 1 and the motor shaft allows the operator to adjust the axial position of the glue-applying wheel 1 on the motor shaft according to the glue application effect during the initial debugging, and to limit the glue-applying wheel 1 by tightening the set screw after the glue-applying wheel 1 is positioned.

[0027] The working principle of this utility model is as follows: During installation, the operator first adjusts the angle of the first toothed plate 10 on the mounting block 9 according to the relative position of the glue-applying roller 1 and the glue-applying plate 3. This allows the first toothed plate 10 to limit the angle of the glue-applying plate 3 via the second toothed plate 11 after positioning, preventing the glue-applying plate 3 from rotating or shifting during subsequent adjustments. After positioning, the first toothed plate 10 is pressed and fixed by tightening the fixing sleeve 12, preventing the first toothed plate 10 from rotating or shifting during subsequent use. After the first toothed plate 10 is fixed, the operator then adjusts the screw-in position of the fixing screw 13 according to the interval between the glue-applying plate 3 and the glue-applying roller 1. This allows the fixing screw 13, after being screwed in, to work with the elastic element 14 to press and limit the axial position of the glue-applying plate 3 from both sides. This allows the adhesive 4 to pass through the gap between the glue-applying plate 3 and the glue-applying roller 1 under the continuous rotation of the glue-applying roller 1, forming a glue layer of a specified thickness.

[0028] When this invention is in use, the pins are conventionally fastened into the pin grooves around the transfer wheel 2. Then, the transfer wheel 2 drives the end of the pin to slide across the adhesive layer on the surface of the coating plate 3 during rotation, thereby causing some of the adhesive 4 to adhere to the pin, thus achieving the adhesive application function. When the external ambient temperature is low, causing the adhesive 4 to harden and solidify, the operator can turn on the axial fan 7 and the heating wire 8 to heat the adhesive 4 and ensure the stability of the adhesive application. When a solidified adhesive layer forms on the surface of the coating wheel 1 after long-term use, causing the gap between the coating plate 3 and the coating wheel 1 to shorten, the operator can adjust the axial distance of the coating plate 3 using the fixing screw 13 to keep the gap between the two and the thickness of the adhesive layer formed after the adhesive 4 passes through the coating plate 3 constant.
