Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment, and in particular to a self-curing UV-curing adhesive dispensing equipment. Background Technology

[0002] Dispensing equipment consists of a dispensing controller, needle, storage container, and motion control system. It precisely dispenses fluid materials through pneumatic pressure, piston, or other driving methods. Self-curing UV adhesive dispensing equipment is widely used because UV adhesives can cure rapidly within seconds to minutes under ultraviolet light, greatly shortening the production cycle. They have excellent flowability and thixotropy, and the equipment can accurately control the amount and shape of dispensing, meeting the needs of high-precision dispensing. The curing process does not produce VOCs, has good environmental performance, meets the requirements of stringent production environments, and has high bonding strength after curing. It is also water-resistant, chemically resistant, and can firmly bond to various materials such as glass, plastic, and metal.

[0003] Existing self-curing UV adhesive dispensing equipment is mainly based on the following working principle: First, the equipment's control system drives the dispensing needle to a designated position via a motion control system according to the preset dispensing path and parameters. Simultaneously, the UV adhesive in the adhesive storage container is extruded under the action of the driving device. The driving method usually includes pneumatic, piston, and screw types. For example, the pneumatic type uses the pressure generated by compressed air to push the adhesive out, and the amount of adhesive dispensed is controlled by adjusting the air pressure and time. The piston type pushes the adhesive through the reciprocating motion of the piston, which has higher precision. After the UV adhesive is extruded from the dispensing needle and applied to the surface of the workpiece, the equipment immediately turns on the ultraviolet light source to irradiate the adhesive. The photoinitiator in the UV adhesive generates free radicals under the excitation of ultraviolet light, which triggers the polymerization reaction of monomers and prepolymers, thereby enabling the adhesive to cure rapidly in a short time and firmly bond the workpieces together.

[0004] In the actual use of self-curing UV adhesive dispensing equipment, the replacement of the spray head has revealed significant operational challenges. As a key component that directly contacts and dispenses UV adhesive, the spray head inevitably suffers from adhesive residue and wear after prolonged use, affecting the accuracy and quality of dispensing. Timely replacement is then necessary. However, the disassembly process for the spray head in current equipment is extremely cumbersome. It requires professionals to follow complex operating manuals and disassemble multiple parts in a specific order, and also necessitates the use of various specialized tools. This process is time-consuming, severely disrupting production continuity and preventing the equipment from returning to normal operation quickly. This significantly limits the high efficiency that self-curing UV adhesive dispensing equipment should possess in production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-curing UV adhesive dispensing device, which aims to improve the problem that complicated operations are required to remove and replace the spray head during the use of the device.

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a self-curing UV-curable adhesive dispensing device, including a working platform 1, a baffle 5 fixedly connected to the top of the working platform 1 to block the fixed platform 20, a control component on one side of the working platform 1 for controlling the operation of the device, a dispensing machine 11 on the top of the working platform 1 for dispensing adhesive onto the item to be dispensed, a sliding component on the outer wall of the working platform 1 for controlling the position of the dispensing machine 11, a connecting strip 12 fixedly connected to the bottom of the dispensing machine 11 for connecting a limiting strip 13, an adhesive storage component on the top of the working platform 1 for storing adhesive, a limiting strip 13 fixedly connected to the bottom of the connecting strip 12 for cooperating with a sliding groove 18 to limit the movement of the spray head 17, a fixing component inside the limiting strip 13 for fixing the spray head 17, a spray head 17 slidably connected to the bottom of the dispensing machine 11 for spraying adhesive, and multiple sliding grooves 18 on the top of the spray head 17 for accommodating the connecting strip 12 and the limiting strip 13;

[0034] The fixing assembly includes a fixing pin 14, a limiting plate 15, and multiple springs 16. The outer wall of the fixing pin 14 is slidably connected to the inside of the limiting strip 13, and cooperates with the springs 16 to fix the spray head 17 to the bottom of the dispensing machine 11. The inner wall of the limiting plate 15 is fixedly connected to the outer wall of the fixing pin 14, limiting the movement range of the fixing pin 14. Each spring 16 is disposed inside the connecting strip 12 to provide elastic force to the fixing pin 14. One end of each spring 16 is fixedly connected to the inside of the connecting strip 12, and the other end of each spring 16 is fixedly connected to the top of the fixing pin 14. The control assembly includes multiple buttons 2, an emergency switch 3, and a start button 4. One end of each button 2 is electrically connected to one side of the work platform 1 for controlling the equipment. The emergency switch... One end of the 3 is electrically connected to one side of the work platform 1 for emergency shutdown of the equipment. One side of the start button 4 is electrically connected to one side of the work platform 1 for starting and stopping the equipment. The sliding assembly includes a moving rod 6, a connecting block 7, and a support plate 8. The bottom end of the moving rod 6 is slidably connected to the outer wall of the work platform 1 for controlling the dispensing machine 11 to move back and forth. The bottom of the connecting block 7 is slidably connected to the top of the moving rod 6 for controlling the dispensing machine 11 to move left and right. One side of the support plate 8 is fixedly connected to one side of the connecting block 7 for connecting the dispensing machine 11. The glue storage assembly includes a glue storage tube 9 and a glue guide tube 10. The outer wall of the glue storage tube 9 is fixedly connected to the inside of the connecting block 7 for storing glue. One end of the glue guide tube 10 is fixedly connected to one end of the glue storage tube 9 for guiding the glue flow.

[0035] Specifically, when the spray nozzle 17 becomes clogged due to the gradual accumulation of UV-cured adhesive residue during prolonged dispensing operations, severely affecting dispensing accuracy and efficiency, it must be replaced promptly. The operator holds the spray nozzle 17 and slowly rotates it clockwise. This causes the inner wall of the spray nozzle 17 to press against the retaining pin 14, forcing the pin 14 to gradually retract into the limiting strip 13, thus unlocking the spray nozzle 17. After unlocking, the operator moves the spray nozzle 17 downwards, allowing the limiting strip 13 to gradually and completely disengage from the sliding groove 18, thereby successfully removing the spray nozzle 17. Afterwards, the operator... The operator takes a brand new spray nozzle 17 from the spare parts, aligns the sliding groove 18 on its top with the position of the limiting strip 13, and then moves the spray nozzle 17 upward, so that the limiting strip 13 slowly enters the sliding groove 18. When the limiting strip 13 reaches the deepest part of the sliding groove 18, the inner wall of the spray nozzle 17 presses against the fixing pin 14 again, causing it to retract into the limiting strip 13. Finally, the operator rotates the spray nozzle 17 counterclockwise to fix the spray nozzle 17. At the same time, the fixing pin 14 is quickly ejected under the elastic force of the spring 16, completely locking the spray nozzle 17 and ensuring its stable operation in subsequent operations.

[0036] Reference Figure 4 and Figure 5The top of the work platform 1 is fixedly connected to a slide rail 19, which provides mechanical support for the sliding of the fixed platform 20. The fixed platform 20 is slidably connected to the outer wall of the slide rail 19 for fixing the items that need to be glued. Multiple sliding blocks 21 are slidably connected inside the fixed platform 20 for driving the fixed strip 23 to move. They cooperate with the second spring 25 to control the contraction of the fixed strip 23. Each sliding block 21 has a sliding column 22 fixedly connected to both sides to limit the movement range of the sliding block 21. Each sliding block 21 has a fixed strip 23 fixedly connected to the top for squeezing and fixing the items that need to be glued. Each fixed strip 23 has a limiting groove 24 inside to accommodate the edge part of the items that need to be glued. Each sliding block 21 has a second spring 25 on one side to provide elastic force for the movement of the fixed strip 23. One end of each second spring 25 is fixedly connected to one side of the sliding block 21, and the other end of each second spring 25 is fixedly connected to the inside of the fixed platform 20.

[0037] Specifically, before the dispensing operation begins, the first step is to secure the item to be dispensed. The operator first holds the fixing strip 23 and pulls it outward. At the same time, the operator takes out the item to be dispensed with the other hand and places it in the center of the fixing platform 20. Then, the operator releases the fixing strip 23. At this time, the fixing strip 23 quickly retracts inward under the elastic force of the second spring 25. The limiting groove 24 on the fixing strip 23 can just allow the edge of the item to be tightly locked in it, forming a stable positioning. Through this process, the item is firmly fixed to the surface of the fixing platform 20, ensuring that there will be no displacement or shaking during the subsequent dispensing operation, providing a stable foundation for accurate dispensing.

[0038] Working Principle: When using the self-curing UV adhesive dispensing equipment, first fix the item to be dispensed. Hold the fixing bar 23 and pull it outwards. Then, the operator takes out the item to be dispensed and places it on the fixing platform 20. Next, release the fixing bar 23, allowing it to retract inwards under the action of spring 25, causing the edge of the item to engage with the limiting groove 24, thus fixing the item to the surface of the fixing platform 20. Then, turn on the equipment by pressing the start button 4. Press button 2 to control the position of the moving rod 6 and connecting block 7 to adjust the position of the dispensing machine 11. After adjusting the dispensing machine 11 above the fixing platform 20, start the dispensing machine 11 to begin dispensing. When the nozzle 17 becomes clogged and needs replacement, first hold the nozzle 17... Rotating it clockwise causes its inner wall to press against the fixing pin 14, causing the fixing pin 14 to retract into the limiting strip 13, thereby unlocking the glue spray head 17. Then, the glue spray head 17 is moved downwards to completely disengage the limiting strip 13 from the sliding groove 18, and the glue spray head 17 is then removed. A new glue spray head 17 is then taken out, and its top sliding groove 18 is aligned with the position of the limiting strip 13. The glue spray head 17 is then moved upwards so that the limiting strip 13 enters the sliding groove 18. When the limiting strip 13 enters the innermost part of the sliding groove 18, the inner wall of the glue spray head 17 presses against the fixing pin 14, causing it to retract into the limiting strip 13. Then, the glue spray head 17 is rotated counterclockwise to fix the glue spray head 17. At the same time, the fixing pin 14 is ejected under the action of the spring 16 to completely lock the glue spray head 17.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
