Abstract
Description
Technical Field
[0001] This application relates to the field of adhesive bonding equipment technology, and in particular to a novel adhesive bonding discharge device. Background Technology
[0002] In the precision coating or potting processes of high-viscosity fluids such as adhesives and sealants, the performance of the pressure dispensing equipment directly affects product quality and production efficiency. Taking the sealing of power batteries for new energy vehicles as an example, if the pressure dispensing equipment cannot accurately control the extrusion amount and coating uniformity of the sealant, the battery casing will not be sealed properly, leading to the intrusion of moisture and impurities, which seriously threatens battery safety and service life. In the field of semiconductor chip packaging, the potting precision requirements for high-viscosity thermally conductive adhesives are extremely high. Even a slight deviation will affect the heat dissipation performance of the chip, thereby reducing the stability of electronic products.
[0003] Current adhesive tape dispensing equipment uses a fixed nozzle design, which makes it difficult to meet the needs of different adhesive tape widths. The fixed nozzle design leads to material waste due to excessively wide adhesive strips or insufficient sealing due to excessively narrow strips, increasing rework rates. To address these issues, we propose a new type of adhesive tape dispensing equipment. Utility Model Content
[0004] The purpose of this application is to provide a novel adhesive dispensing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A novel adhesive dispensing device includes a glue cylinder. An adjustable dispensing assembly is provided at the bottom of the glue cylinder. The adjustable dispensing assembly includes a dispensing head. A plug is slidably connected to the inner wall of the dispensing head. An L-shaped plate is fixedly connected to both the front and back of the plug. A U-shaped plate is sleeved on the outside of each L-shaped plate. The ends of a group of U-shaped plates that are close to each other are respectively connected to the outer surface of the dispensing head. The glue cylinder has a dispensing structure inside.
[0007] In a further embodiment, a set of equally spaced locking blocks are fixedly connected to the opposite sides of a group of L-shaped plates, and a through groove is provided on the upper surface of each U-shaped plate, with a moving block slidably connected to the inner wall of each through groove.
[0008] In a further embodiment, each through groove has a groove on its inner wall, each groove has a movable plate slidably connected to its inner wall, each movable plate has a set of guide rods slidably connected to it, the top and bottom ends of each guide rod are connected to the inner wall of the groove, and each guide rod has a spring sleeved on its outer surface.
[0009] In a further embodiment, each of the L-shaped plates has a stop block fixedly connected to one of its opposite sides.
[0010] In a further embodiment, the discharge structure includes a push rod sleeved inside the rubber cylinder, and a handle is fixedly connected to the top end of the push rod.
[0011] In a further embodiment, a sealing cover is slidably connected to the outer surface of the push rod, and the sealing cover is sleeved on the outside of the rubber tube.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This application, through the adjustable dispensing component, allows the plug to move to different degrees inside the dispensing head, thereby adjusting the width of the glue extruded inside the dispensing head. This makes it suitable for different widths of glue application requirements. Through the cooperation of the push rod, handle, and sealing cap, the movement of the push rod can squeeze the glue out of the glue tube, while the sealing cap can seal the top of the glue tube to prevent foreign objects from falling into the glue tube.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 In this utility model, a novel adhesive dispensing device includes a glue cylinder 1. The dispensing structure includes a push rod 5 fitted inside the glue cylinder 1. A handle 4 is fixedly connected to the top of the push rod 5. By holding the handle 4, the push rod 5 can be pushed, which will squeeze the glue inside the glue cylinder 1, thereby extruding glue strips. A sealing cover 2 is slidably connected to the outer surface of the push rod 5. The sealing cover 2 is fitted outside the glue cylinder 1. The sealing cover 2 can be fitted on the top of the glue cylinder 1 to prevent impurities from falling into the glue cylinder 1.
[0023] An adjustable dispensing assembly 3 is provided at the bottom of the glue cylinder 1. The adjustable dispensing assembly 3 includes a dispensing head 301. A plug 302 is slidably connected to the inner wall of the dispensing head 301. The width of the glue strip extruded from the dispensing head 301 can be adjusted by adjusting the plug 302. An L-shaped plate 303 is fixedly connected to both the front and back of the plug 302. A U-shaped plate 304 is sleeved on the outside of each L-shaped plate 303. The ends of a group of U-shaped plates 304 that are close to each other are respectively connected to the outer surface of the dispensing head 301. By using the connection between the L-shaped plate 303 and the U-shaped plate 304, the plug 302 can be stabilized outside the dispensing head 301.
[0024] The inner part of the rubber cylinder 1 is equipped with a discharge structure. A set of L-shaped plates 303, on opposite sides, are fixedly connected to a set of equally spaced locking blocks 305. Each U-shaped plate 304 has a through groove 306 on its upper surface. A moving block 307 is slidably connected to the inner wall of each through groove 306. Each through groove 306 has a groove 308 on its inner wall. A moving plate 309 is slidably connected to the inner wall of each groove 308. A set of guide rods 310 is slidably connected to each moving plate 309. The top and bottom ends of each guide rod 310 are connected to the inner wall of the groove 308. A spring 311 is fitted onto the outer surface of each guide rod 310. A plug is also included. When 302 moves, it will simultaneously drive the L-shaped plate 303. When the L-shaped plate 303 moves, it will pull the moving block 307. When the moving block 307 moves, it will be squeezed by the locking block 305. The moving block 307 will then move upward and drive the moving plate 309. The moving plate 309 will compress the spring 311. When the plug 302 moves to the appropriate position, the spring 311 will extend and push the moving plate 309, which can push the moving block 307 back into the locking block 305, thereby locking the L-shaped plate 303. This will make the plug 302 stable in the dispensing head 301, which can ensure that the dispensing head 301 can extrude adhesive strips of different widths, thus meeting the pressing needs of different widths.
[0025] Each L-shaped plate 303 has a stop block 312 fixedly connected to one of its opposite sides. The stop block 312 can limit the movement of the L-shaped plate 303 and prevent the L-shaped plate 303 from separating from the U-shaped plate 304.
[0026] The working principle of this application is as follows: When it is necessary to adjust the glue dispensing width inside the glue dispensing head 301, the plug 302 can be pushed and pulled. When the plug 302 moves, it will simultaneously drive the L-shaped plate 303. When the L-shaped plate 303 moves, it will pull the moving block 307. When the moving block 307 moves, it will be squeezed by the locking block 305. The moving block 307 will then move upward and drive the moving plate 309. The moving plate 309 will then compress the spring 311. When the plug 302 moves to the appropriate position, the spring 311 will extend and push the moving plate 309, which can push the moving block 307 back into the locking block 305, thereby locking the L-shaped plate 303 and making the plug 302 stable in the glue dispensing head 301. This ensures that the glue dispensing head 301 can extrude glue strips of different widths, thus meeting the glue pressing needs of different widths.
[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
