Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to an extrusion-type light-curing adhesive applicator. Background Technology

[0002] Currently, adhesive tape is needed for bonding and fixing modules in electronic manufacturing and new energy vehicle lithium batteries. Most of the tapes used are dedicated UV-curing tapes. The tape is applied between the two modules that need to be bonded, and then irradiated with a UV lamp to cure the adhesive in the tape, thus firmly bonding the two modules. However, such tapes often cannot cover all application scenarios. For example, some small parts have small gaps that cannot be bonded by tape. Therefore, UV-curing adhesives are needed. UV-curing adhesives need to be injected using a dedicated injection head or nozzle while being irradiated with a UV lamp.

[0003] However, existing nozzles are mostly fixed designs and have a single extrusion shape, which cannot adapt to different sizes, shapes, or complex coating patterns and surfaces. Moreover, they are mostly extruded by manually squeezing the glue tube, so the extrusion volume cannot be controlled. Furthermore, the extruded glue needs to be cured under ultraviolet light or other light sources, which is a complicated process that wastes a lot of operation time and affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion-type light-curing adhesive applicator that can precisely control the amount of adhesive extruded and the coating shape to meet the fine coating needs of different products. At the same time, different shapes and sizes of applicators can be changed according to different coating tasks to adapt to various complex coating patterns and surfaces. In addition, the extruded adhesive is simultaneously irradiated and cured to ensure bonding quality and improve production efficiency.

[0005] To achieve the above objectives, an extrusion-type UV-curable adhesive applicator is provided, comprising: a glue tube; a limiting sleeve fixedly connected to the left side of the glue tube; a micro motor fitted and fixedly located at the center of the left side of the limiting sleeve; a rotating drum fixedly connected to the right output end of the micro motor; a threaded extrusion rod threadedly connected to the inner side of the rotating drum; the rotating drum and the limiting sleeve rotatably engaging; the threaded extrusion rod and the limiting sleeve slidingly engaging; the right end of the threaded extrusion rod extending into the inner side of the glue tube and a piston fixedly connected thereto; the piston and the glue tube slidingly engaging; an extrusion head fitted and fixedly located on the inner side of the right end of the glue tube; a liquid guide tube fixedly connected to the center of the inner side of the extrusion head in a left-right direction; a retaining sleeve fitted and fixedly located on the upper right side of the extrusion head; a sleeve connected and fixedly located on the inner side of the right end of the retaining sleeve; a diffuser UV lamp fixedly connected to the right end of the sleeve; a control button fitted and slidably connected to the bottom right side of the glue tube; and wires connected to the power terminals of the diffuser UV lamp and the micro motor. Do not connect the control button along the inner side of the sleeve, ferrule, and inner wall of the glue tube for synchronous transmission and control. The inner right end of the extruder head is fixed with an insert rod, and the outer right end of the insert rod is fitted with several combination nozzles. Each combination nozzle has a slot at its top center. A micro motor drives the rotating drum to rotate, which in turn drives the threaded extrusion rod to output linearly, allowing the piston to advance slowly and evenly inside the glue tube. This ensures that the glue is extruded at the same rate, accurately controlling the extrusion volume. Compared to manual extrusion of the bottle, this method is more stable and efficient. Several combination nozzles are inserted and fixed to the extruder head. Different shapes and sizes of nozzles can be changed according to different coating tasks to adapt to various complex coating patterns and surfaces. In addition, a diffused ultraviolet lamp is mounted directly above the combination nozzles and is synchronously controlled by the control button along with the micro motor. This allows for synchronous irradiation and curing of the extruded glue, ensuring bonding quality and improving production efficiency.

[0006] According to the aforementioned extrusion-type UV-curable adhesive applicator, the combined applicator is divided into a dot application applicator and a line application applicator. The dot application applicator is used for dot and line application operations, while the line application applicator is used for line and surface application operations, allowing for the selection of more suitable applicators as needed.

[0007] According to the extrusion-type UV-curing adhesive applicator, the right end of the diffused UV lamp is tilted downwards, and a shock-absorbing rubber ring is fixed around the outer side of the left end of the diffused UV lamp. This ensures irradiation intensity while providing a certain degree of impact protection.

[0008] According to the aforementioned extrusion-type UV-curable adhesive applicator, a retaining seat engages with the top of the slot, and elastic pads are fixedly connected to the top of the retaining seat in both the left and right directions. The top ends of the elastic pads are fixedly connected to a sleeve. The elastic pads are positioned within the slot to maintain the relative position of the diffuser UV lamp to the nozzle extrusion opening.

[0009] According to the extrusion-type UV-curable adhesive applicator, the outer isolation frame of the micro motor is provided with a sleeve, and the right side of the sleeve is engaged and fixed with the limiting bushing. This provides isolation and protection for the micro motor while maintaining the smoothness between the adhesive tube, the limiting bushing, and the sleeve.

[0010] According to the extrusion-type UV-curable adhesive applicator, an anti-slip sleeve is fixedly attached to the outer side of the adhesive cartridge, and a slot is provided on the bottom right side of the anti-slip sleeve corresponding to the control button. This improves the stability of the hand grip and ensures the quality of adhesive application.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this invention, a micro motor is used to drive the rotating drum, which in turn drives the threaded extrusion rod to output linearly. This allows the piston to advance slowly and uniformly within the glue cylinder, ensuring that the glue is extruded at the same rate. This allows for precise control of the extrusion volume and is more stable and efficient than manual bottle extrusion. Several combined nozzles are inserted and locked to the extrusion head, allowing for the replacement of nozzles of different shapes and sizes to adapt to various complex coating patterns and surfaces, depending on the specific glue application task. Furthermore, a diffused ultraviolet lamp is mounted directly above the combined nozzles and is synchronously controlled by a control button to simultaneously irradiate and cure the extruded glue, ensuring bonding quality and improving production efficiency.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] An extrusion head 8 is fitted and fixed to the inner side of the right end of the glue tube 1. A liquid guide tube 9 is fixedly connected to the center of the inner side of the extrusion head 8 in a left-right direction.

A diffused ultraviolet lamp 12 is fixedly connected to the right end of the sleeve 11. The right end of the diffused ultraviolet lamp 12 is tilted downward. An anti-collision rubber ring is fixed around the outer side of the left end of the diffused ultraviolet lamp 12. A control button 19 is fitted and slidably connected to the bottom right side of the glue tube 1. The power terminals of the diffused ultraviolet lamp 12 and the micro motor 4 are connected to wires 18, which are connected to the control button 19 along the inner side of the sleeve 11, the ferrule 10 and the inner wall of the glue tube 1, respectively, and perform synchronous transmission and control.

[0025] Working principle: By setting up a micro motor 4 to drive the rotating drum 5 to rotate, the threaded extrusion rod 6 outputs linearly, which allows the piston 7 to be slowly and uniformly pushed forward in the glue cylinder 1, so that the glue is extruded at the same rate, accurately controlling the extrusion amount. Compared with the manual extrusion method, it is more stable and efficient. At the same time, several combination glue nozzles are set and inserted into the extrusion head 8 for fixed fixation.

[0026] The simplified operation steps are as follows: Grasp the anti-slip sleeve 20 and press the control button 19 to simultaneously control the advancement of the piston 7 and the activation of the diffused ultraviolet lamp 12, thereby extruding the light-curing adhesive from the glue tube 1. The flow rate and shape of the adhesive are precisely controlled by the combined glue nozzle. The extruded adhesive is rapidly cured under the irradiation of the ultraviolet light source, realizing functions such as rapid bonding or coating.
