[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4This utility model provides a technical solution: a display screen adhesive coating device, comprising: a working platform 1, the working platform 1 having an internal mounting groove 3 for mounting and fixing components such as a first linear motor 6, providing basic support and installation space for the motion mechanism of the entire device; the mounting groove 3 housing the first linear motor 6, capable of generating linear driving force to drive connected components to perform precise linear movement, thereby achieving position adjustment of the adhesive coating device in one direction; a sliding groove 13 is provided above the mounting groove 3, cooperating with a first fixing block 14 to ensure that the first fixing block 14 and its connected components can slide stably and smoothly above the mounting groove 3, guiding their movement direction; the output end of the first linear motor 6 is fixedly connected to a first... The fixed block 14 transmits the power of the first linear motor 6 to subsequent components, causing them to move in tandem with the motor. The first fixed block 14 is slidably connected to the sliding groove 13, ensuring the stability and accuracy of the first fixed block 14 during sliding and reducing movement deviation. Two support blocks 15 are fixedly connected to the upper surface of the first fixed block 14, providing support and mounting positions for subsequent components such as the first slide rod 16 and the second linear motor 17, maintaining them at appropriate heights and positions. The first slide rod 16 is fixedly connected inside each of the two support blocks 15, providing guidance and support for the sliding of the second linear motor 17, enabling it to move smoothly in a straight line on the first slide rod 16, further precisely controlling the adhesive application position. There are two first slide rods 16. A second linear motor 17 is disposed between the two first sliding rods 16. Guided by the first sliding rods 16, it generates a linear driving force independent of the direction of the first linear motor 6, enabling precise position adjustment of the gluing device in another direction for gluing operations on the display screen at different positions. The output end of the second linear motor 17 is fixedly connected to four second fixing blocks 18, which transmit the power of the second linear motor 17 to components such as connecting blocks 19, driving them to perform corresponding movements. Connecting blocks 19 are fixedly connected to the upper surfaces of the four second fixing blocks 18, serving as intermediate connecting components that connect the second fixing blocks 18 and the limiting plates 20, transmitting power and movement. Four limiting plates 20 are fixedly connected to the side walls of the connecting blocks 19 to limit and fix the position of the display screen. The four limiting plates 20 are symmetrically arranged on the front and rear sides of the connecting block 19 to ensure that the display screen does not shift during the glue application process, thus guaranteeing the accuracy and uniformity of the glue application. Each of the four limiting plates 20 has an adjustment groove 21 inside, providing installation and movement space for components such as the first contact block 24 and the second sliding rod 22, facilitating fine-tuning according to the size of the display screen. The inner surface of the adjustment groove 21 is fixedly connected to the second sliding rod 22, which cooperates with the first contact block 24, allowing the first contact block 24 to slide stably within the adjustment groove 21, achieving adaptive adjustment for display screens of different sizes. The outer surface of the second sliding rod 22 is provided with a spring 23, providing elastic force so that the first contact block 24 can move flexibly within a certain range and maintain appropriate pressure on the display screen.The system effectively secures the display screen while preventing damage from excessive pressure. One end of the spring 23 abuts against a first abutment block 24. Under the action of the spring 23, the spring 23 contacts the display screen and provides a stable resisting force, adapting to display screens of different sizes and ensuring their stability during the adhesive application process. The first abutment block 24 is slidably connected to the second slide bar 22, ensuring the smooth and accurate movement of the first abutment block 24, allowing it to adjust its position according to the elastic deformation of the spring 23. Several second abutment blocks 25 are fixedly connected to the upper surfaces of the four limiting plates 20, further enhancing the securing effect on the display screen and preventing it from shaking or shifting during the adhesive application process.
[0023] The second linear motor 17 is slidably connected to the two first slide rods 16, ensuring the motion accuracy and stability of the second linear motor 17, enabling it to accurately reach the predetermined position under the constraint of the first slide rods 16. The second linear motor 17 is located inside the support block 15, making reasonable use of space and making the entire device structure more compact and stable. The spring 23 is sleeved with the second slide rod 22, ensuring the secure installation of the spring 23 and the effective transmission of elastic force, allowing it to function normally. The first abutment block 24 is located in the adjustment groove 21, allowing it to be effectively adjusted within the adjustment groove 21 to adapt to different sized displays. The sliding groove 13 and the mounting groove 3 are internally connected, ensuring the continuity and integrity of the movement of components such as the first fixed block 14, enabling the entire motion mechanism to work in a coordinated manner. The first fixed block 14 extends into the interior of the mounting groove 3, allowing the first fixed block 14 to be tightly connected to the first linear motor 6, ensuring the effective transmission of power. To ensure the accuracy of delivery and movement, two limiting blocks 4 are fixedly connected to the side wall of the first linear motor 6 to limit the movement range of the first linear motor 6, preventing it from exceeding the predetermined stroke during operation and ensuring the safety and stability of the device. The two limiting blocks 4 are symmetrically arranged on the front and rear sides of the first linear motor 6, and each limiting block 4 is equipped with two positioning bolts 5. The position of the limiting blocks 4 can be precisely adjusted and fixed through the positioning bolts 5, further optimizing the movement range and accuracy of the first linear motor 6. The two positioning bolts 5 are symmetrically arranged on the left and right sides of the limiting blocks 4. Four support legs 2 are fixedly connected to the lower surface of the work platform 1 to provide stable support for the entire device, allowing it to be placed stably on the workbench and ensuring the smooth progress of the glue application operation. A support frame 8 is fixedly connected to the upper surface of the work platform 1 to support components such as the tank 7 and the wire groove 9, ensuring the structural integrity and stability of the entire glue application device.
[0024] A tank 7 is fixedly connected to the side wall of the support frame 8 to store the adhesive required for gluing, providing a continuous supply of adhesive for the gluing operation. A wire groove 9 is opened inside the support frame 8 to provide a wiring channel for the delivery pipe 10, so that it can be neatly and safely connected to various components, avoiding messy wiring from affecting the normal operation of the device. The delivery pipe 10 is set inside the wire groove 9 to deliver the adhesive in the tank 7 to the pump 11, realizing the transmission and supply of adhesive. The pump 11 is fixedly connected to the lower surface of the support frame 8, generating suction to draw and pressurize the adhesive in the tank 7 through the delivery pipe 10, so that it can be delivered to the pump head 12 at a suitable pressure and flow rate. The pump head 12 is fixedly connected to the output end of the pump 11, which evenly sprays or applies the pressurized adhesive to the display screen to achieve precise gluing operation. The delivery pipe 10 is adapted to the pump 11 and the tank 7 respectively to ensure that the adhesive can flow smoothly between the tank 7, the pump 11 and the pump head 12, ensuring the continuity and stability of the gluing process.
[0025] Working principle: The display screen is placed on the working platform 1, positioned within the area enclosed by the limiting plate 20, with its edges in close contact with the limiting plate 20. It is fixed by the second contact block 25 and the first contact block 24 under the action of the spring 23. Parameters such as the glue application speed, glue flow rate, start and end positions are set through an external controller or device control panel. The power of the pump 11 is turned on, causing it to draw glue from the tank 7 and pressurize it. At the same time, the first linear motor 6 and the second linear motor 17 are started. The former slides on the sliding groove 13 through the first fixing block 14, driving related components to adjust the X-axis position. The latter slides on the first slide rod 16, driving the pump head 12 to move along the Y-axis, allowing the pump head 12 to accurately reach the glue application position. After the pump 11 starts running, the glue is evenly applied to the display screen. During glue application, attention is paid to uniformity and integrity. The two motors work together to control the movement of the glue application head according to a preset path, applying glue horizontally first along the long side and then vertically along the short side. After the glue application is completed, the power of the pump 11 is turned off, and the two motors are controlled to return the glue application head to the initial position. The display screen is then removed and placed in a designated location for subsequent processing or drying and curing.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
