Description

Technical Field

[0001] This utility model relates to the field of machinery, and more specifically, to a touch screen adhesive coating mechanism. Background Technology

[0002] Traditional touchscreen adhesive application processes include dispensing, scraping, and potting. These processes have many drawbacks. For example, dispensing requires manually applying a border first to prevent glue overflow, then dispensing and waiting for the glue to level itself. This is labor-intensive and cannot guarantee uniform glue thickness. Scraping also requires manually applying the border first, then dispensing and scraping, which is time-consuming and labor-intensive. Potting is purely manual, requiring the border to be applied first and then the product to be bonded. The dispensing needle is inserted through the gap in the border to pour the glue. This is not only labor-intensive and time-consuming, but also prone to uneven glue application and gaps, allowing air and dust to enter and affecting product quality.

[0003] Currently, adhesive coating mechanisms on the market use rollers for coating. However, dust easily accumulates during the coating process, affecting the coating effect. Furthermore, the adhesive tends to flow during extrusion after coating, which also affects the coating effect. How to invent a touch screen adhesive coating mechanism to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a touch screen adhesive coating mechanism, which aims to improve the problems of residual dust affecting coating and adhesive backflow.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a touch screen adhesive coating mechanism, including a load-bearing plate, a movable groove on the load-bearing plate, a motor fixedly installed inside the movable groove, a lead screw fixedly installed at one end of the motor, and an exhaust assembly on the side wall of the load-bearing plate. The exhaust assembly includes a protective railing, which is fixedly connected to the side wall of the load-bearing plate. The mechanism also includes:

[0007] A stamping assembly, which is fixedly connected to the load-bearing plate;

[0008] A positioning component, which is located above the load-bearing plate.

[0009] Preferably, an airbag is slidably installed on the inner wall of the guardrail, an exhaust plate is installed at one end of the airbag, and an exhaust pipe is fixedly installed on the inner wall of the exhaust plate.

[0010] Preferably, the pressing assembly includes a piston cylinder, which is fixedly connected to the side wall of the load-bearing plate. A load-bearing column is slidably connected to the inner wall of the piston cylinder. The load-bearing column is T-shaped and a spring is sleeved on the outer wall of the load-bearing column.

[0011] Preferably, the two ends of the spring are fixedly connected to the side wall of the load-bearing column and the inner wall of the piston cylinder, respectively. A load-bearing block is fixedly installed at the end of the load-bearing column away from the piston cylinder. A coater is rotatably connected to the inner wall of the load-bearing block, and the coater is located above the airbag.

[0012] Preferably, the positioning component includes a base plate, a movable block is fixedly installed on the side wall of the base plate, the inner wall of the movable block is threadedly connected to a lead screw, a positioning groove is formed on the side wall of the base plate, the movable block 402 is slidably connected to the inner wall of the movable groove 5, and the end of the lead screw 7 away from the motor 6 is rotatably connected to the inner wall of the movable groove 5.

[0013] Preferably, the inner wall of the positioning groove is provided with air guide holes, the positions of the air guide holes correspond one-to-one with the positions of the exhaust pipes, and a push plate is fixedly installed on the side wall of the base plate, the other end of the push plate being fixedly connected to the side wall of the exhaust plate.

[0014] The beneficial effects of this utility model are:

[0015] During coating, the motor rotates, which in turn moves the lead screw, moving block, substrate, and touch screen placed on the substrate. This movement, in turn, moves the push plate and squeezes the exhaust plate, allowing the gas inside the airbag to be discharged from the exhaust pipe and blown onto the surface of the touch screen through the air guide hole. This helps to remove dust from the touch screen surface and prevents dust from affecting the processing effect. After the pressing and coating is completed, the gas blown out from inside the airbag can also blow on the freshly coated touch screen to prevent the adhesive on the touch screen surface from flowing and affecting the coating efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example, refer to Figures 1-3 A touchscreen adhesive coating mechanism includes a load-bearing plate 1, a moving groove 5 on the load-bearing plate 1, a motor 6 fixedly installed inside the moving groove 5, a lead screw 7 fixedly installed at one end of the motor 6, and an exhaust assembly 2 on the side wall of the load-bearing plate 1. The exhaust assembly 2 includes a protective railing 201, which is fixedly connected to the side wall of the load-bearing plate 1. The mechanism also includes:

[0023] The stamping assembly 3 is fixedly connected to the load-bearing plate 1.

[0024] Positioning component 4 is located above the load-bearing plate 1.

[0025] Furthermore, an airbag 202 is slidably installed on the inner wall of the guardrail 201. An exhaust plate 203 is installed at one end of the airbag 202. An exhaust pipe 204 is fixedly installed on the inner wall of the exhaust plate 203. The positioning component 4 includes a base plate 401. A moving block 402 is fixedly installed on the side wall of the base plate 401. The inner wall of the moving block 402 is threadedly connected to the lead screw 7. A positioning groove 403 is opened on the side wall of the base plate 401. The moving block 402 is slidably connected to the inner wall of the moving groove 5. The end of the lead screw 7 away from the motor 6 is rotatably connected to the inner wall of the moving groove 5. An air guide hole 404 is opened on the inner wall of the positioning groove 403. The position of the air guide hole 404 corresponds one-to-one with the position of the exhaust pipe 204. A push plate 405 is fixedly installed on the side wall of the base plate 401. The other end of the push plate 405 is fixedly connected to the side wall of the exhaust plate 203.

[0026] It should be noted that: when the touch screen to be processed is placed in the positioning groove 403, the motor 6 is started and the lead screw 7 is rotated. Since the moving block 402 is threadedly connected to the lead screw 7, the substrate 401 is driven to move laterally along the moving groove 5 of the load-bearing plate 1. At this time, the touch screen placed in the positioning groove 403 of the substrate 401 moves synchronously. During the movement of the substrate 401, the push plate 405 on its side wall pushes the exhaust plate 203 to move inward, so that the air bag 202 is squeezed and contracted, so that the internal space of the air bag 202 gradually shrinks and the volume of the internal gas decreases accordingly. The shrinkage of the gas volume will cause the pressure to rise sharply, so that the high-pressure gas inside is squeezed out through the exhaust pipe 204 and blown to the surface of the touch screen through the air guide hole 404 on the substrate 401, so as to remove the dust on the surface of the touch screen and avoid the dust from affecting the subsequent coating accuracy, thereby affecting the coating result.

[0027] Reference Figures 2-3 Furthermore, the pressing assembly 3 includes a piston cylinder 301, which is fixedly connected to the side wall of the load-bearing plate 1. A load-bearing column 302 is slidably connected to the inner wall of the piston cylinder 301. The load-bearing column 302 is arranged in a "T" shape. A spring 303 is sleeved on the outer wall of the load-bearing column 302. The two ends of the spring 303 are fixedly connected to the side wall of the load-bearing column 302 and the inner wall of the piston cylinder 301, respectively. A load-bearing block 304 is fixedly installed at the end of the load-bearing column 302 away from the piston cylinder 301. A coater 305 is rotatably connected to the inner wall of the load-bearing block 304. The coater 305 is located above the airbag 202.

[0028] It should be noted that as the motor 6 continues to rotate, the substrate 401 moves to a position below the coater 305. The coater 305 then contacts the substrate 401. Due to the slope at the front end of the substrate 401, the coater 305 begins to move at the front end of the substrate 401. Under the action of friction, the coater 305 begins to rotate. During the upward movement of the coater 305, it is supported by the substrate 401, causing the coater 305 to drive the support block 304 and the support column 302 to slide upward along the piston cylinder 301 under the elastic force of the spring 303, until the coater 305 applies adhesive to the touchscreen, thus making the coater 305 contact the touchscreen surface. The close contact increases coating efficiency and prevents air bubbles from forming during coating through appropriate compression. It also prevents excessive pressure during contact from causing damage to the touchscreen. This ensures that the adhesive is evenly applied to the touchscreen surface. At the same time, the airbag 202 continues to be compressed, and the applicator 305 continues to apply adhesive to the cleaned display screen. The display screen, which has already been coated with adhesive, is continuously blown by the exhaust airflow. On the one hand, the airflow tension inhibits the flow of adhesive, preventing uneven adhesive layer thickness caused by adhesive flow, thereby improving the coating success rate. On the other hand, the continuous airflow can accelerate the initial curing of the adhesive surface, improving coating efficiency.

[0029] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
