Description

Technical Field

[0001] This utility model relates to the field of touch screen coating technology, specifically a coating machine for touch screen production. Background Technology

[0002] Currently, there are many types of glue applicators, such as automatic glue applicators (programmable control of glue dispensing amount and path) and manual glue guns (suitable for small batches or repairs). Each type of glue applicator has its own advantages and is commonly seen in touch screen processing plants.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: When applying glue to small batches of touch screens using existing glue-applying machines for touch screen production, personnel need to manually apply glue in a "reverse" pattern using a handheld glue gun. However, the existing method is prone to issues of too much or too little glue during the "reverse" glue application process: too much glue will cause glue overflow to contaminate the screen or surrounding structure, while too little glue will affect the bonding strength, both of which may lead to secondary problems such as an increase in the defect rate. Therefore, we propose a glue-applying machine for touch screen production. Utility Model Content

[0004] The purpose of this utility model is to provide a glue coating machine for touch screen production, which solves the problem that the existing method mentioned in the background art is prone to too much or too little glue in the "U" shaped glue coating process: too much glue will cause glue overflow to contaminate the screen or surrounding structure, while too little glue will affect the bonding strength, both of which may lead to secondary problems such as increased defect rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue coating machine for touch screen production, comprising a carrier board, a glue storage mechanism, a glue dispensing mechanism, and a connecting mechanism;

[0006] A herringbone frame is fixedly installed in the middle of the upper surface of the carrier plate, and a concave plate is inserted in the herringbone frame. A touch screen is inserted in the groove of the concave plate.

[0007] A gantry frame is fixedly installed on the outer side of the upper surface of the carrier plate, and a glue storage mechanism is fixedly installed at the top inside the gantry frame;

[0008] Support plates are fixedly installed on both sides of the inner middle part of the gantry frame, and a glue dispensing mechanism is fixedly installed between the two sets of support plates.

[0009] The dispensing mechanism is equipped with a connecting mechanism at its top.

[0010] As an optional solution to the technical solution of this application, the glue storage mechanism includes a liquid storage tank, a liquid pump is connected to the bottom of the front wall of the liquid storage tank, a heating tube is installed inside the liquid storage tank, and a feed pipe is connected to the top of one side of the liquid storage tank.

[0011] As an optional solution to the technical solution of this application, the glue dispensing mechanism includes a glue dispensing plate, and several sets of uniformly arrayed glue dispensing pin holes are opened around the bottom wall of the glue dispensing plate, and a glue receiving groove is opened in the center of the glue dispensing plate.

[0012] As an optional solution to the technical solution of this application, a movable plate is placed at the top of the adhesive tank, and a sealing strip is fixedly installed on the outer edge of the movable plate. A handle and a guide tube are fixedly installed on both sides of the top of the movable plate, and an inner rod is movably inserted through the guide tube, with the top end of the inner rod fixedly connected to the liquid storage tank.

[0013] As an optional solution to the technical solution of this application, the connecting mechanism includes a hose, the top end of which is connected to the through pipe of the liquid pump via a clamp, and the bottom end of which is connected to a feed pipe.

[0014] As an optional solution to the technical solution of this application, the outer ends of the two sets of support plates are fixedly installed with a locking block. The locking block is in a slot, and the slot has an opening on the side near the support plate. The slot is fixed on the gantry frame.

[0015] As an optional solution to the technical solution of this application, a flange is fixedly installed at the bottom end of the hose, a nut is provided on the outer side of the flange, and the hose moves through the top wall of the nut. The nut is screwed to the external thread of the feed pipe through the internal thread, and the feed pipe is fixedly inserted inside the movable plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model discloses a glue applicator for touchscreen production. It is equipped with glue dispensing needles, a movable plate, and a liquid pump. During operation, after the touchscreen is positioned in the concave plate, the glue is dispensed via the liquid pump by holding the handle. The machine stops feeding by observing the scale on the front wall of the liquid tank. Then, pressing down the handle causes the movable plate to move downwards due to the silicone rubber sealing strip, allowing the glue to be extruded from the evenly distributed glue dispensing needles, forming continuous and uniformly spaced glue dots that are applied to the touchscreen. As the glue is extruded, adjacent glue dots melt together. After bonding, a uniform "U"-shaped glue line is formed. Compared with traditional manual glue guns, this structure effectively avoids the problem of discontinuous or uneven glue line caused by unstable hand gestures or fluctuations in glue pressure. It significantly improves the process consistency and yield of small-batch glue application and solves the problem mentioned in the background technology: "In the existing method, the glue amount is prone to being too much or too little during the "U"-shaped glue application process: too much glue will cause glue overflow to contaminate the screen or surrounding structure, while too little glue will affect the bonding strength, both of which may lead to secondary problems such as increased defect rate."

[0018] 2. This utility model discloses a glue applicator for touch screen production. By setting a locking block and a nut, the movable plate is limited by the circular frame and the locking block can be moved upward to disassemble the glue dispensing mechanism. At the same time, the flexible tube can be separated from the movable plate by rotating the nut. The machine allows for flexible replacement of suitable components such as the concave plate, glue dispensing plate, and movable plate, which improves the adaptability of the equipment to different production batches and product models and has a wide range of applications.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a glue coating machine for touch screen production, including a carrier plate 1, a glue storage mechanism, a glue dispensing mechanism, and a connecting mechanism; a U-shaped frame 11 is fixedly installed in the middle of the upper surface of the carrier plate 1, a concave plate 12 is inserted in the U-shaped frame 11, and a touch screen is inserted in the groove of the concave plate 12; a gantry frame 2 is fixedly installed on the outer side of the upper surface of the carrier plate 1, and a glue storage mechanism is fixedly installed at the top of the gantry frame 2; support plates 5 are fixedly installed on both sides of the middle part of the gantry frame 2, and a glue dispensing mechanism is fixedly installed between the two sets of support plates 5; a connecting mechanism is provided at the top of the glue dispensing mechanism;

[0027] First, after the glue applicator is placed or fixed, the glue storage mechanism can deliver the glue towards the glue dispensing mechanism. Then, by manually adjusting the glue dispensing component, the glue can be evenly dripped onto the touch screen. Compared with the existing method, this can improve the quality of glue application.

[0028] The glue storage mechanism includes a liquid storage tank 21, with a liquid pump 22 connected to the bottom of the front wall of the liquid storage tank 21. A heating tube is installed inside the liquid storage tank 21, and a feed pipe is connected to the top of one side of the liquid storage tank 21. The glue dispensing mechanism includes a glue dispensing plate 3, with several sets of uniformly arrayed glue dispensing pinholes 33 opened around the bottom wall of the glue dispensing plate 3. A glue receiving trough 32 is opened in the middle of the glue dispensing plate 3. A movable plate 31 is placed on the top of the glue receiving trough 32, and a sealing strip 34 is fixedly installed on the outer edge of the movable plate 31. A handle and a guide tube are fixedly installed on the top two sides of the movable plate 31, respectively. An inner rod moves through the guide tube, and the top of the inner rod is fixedly connected to the liquid storage tank 21. The connecting mechanism includes a hose 4, with the top of the hose 4 connected to the through pipe of the liquid pump 22 through a clamp, and a feed pipe 43 connected to the bottom of the hose 4.

[0029] For details, please refer to Figure 1-4 During the use of the glue applicator, after the touch screen is positioned in the concave plate 12, the glue can be dispensed by holding the handle and pumped by the liquid pump 22. The feeding can be stopped by observing the scale on the front wall of the liquid tank 21. Then, the handle is pressed down. Due to the setting of the silicone rubber sealing strip 34, the movable plate 31 moves down, allowing the glue to be squeezed out from the glue dispensing needle holes 33 evenly distributed around the perimeter, forming continuous glue dots with consistent spacing. The glue is then applied to the touch screen. As the glue is pressed out, adjacent glue dots merge to form a uniform "U"-shaped glue line. Compared with the traditional manual glue gun, this structure effectively avoids the problem of discontinuous or uneven glue lines caused by unstable hand gestures or fluctuations in glue dispensing pressure, significantly improving the process consistency and yield of small-batch glue application.

[0030] For further details, please refer to [link / reference]. Figure 1-4 Two sets of support plates 5 are fixedly installed with a locking block 51 at their outer ends. The locking block 51 is in the locking groove 52, and the locking groove 52 has an opening on the side near the support plate 5. The locking groove 52 is fixed on the gantry frame 2. A flange 41 is fixedly installed at the bottom end of the hose 4. A nut 42 is covered on the outside of the flange 41, and the hose 4 moves through the top wall of the nut 42. The nut 42 is screwed to the external thread of the feed pipe 43 through the internal thread, and the feed pipe 43 is fixedly inserted through the movable plate 31.

[0031] Because the concave plate 12 is limited in movement by the circular frame 11 and the movable block 51 can be moved upward, the dispensing mechanism can be disassembled. At the same time, the hose 4 can be separated from the movable plate 31 by rotating the nut 42. The appropriate components such as the concave plate 12, dispensing plate 3 and movable plate 31 can be flexibly replaced, which improves the adaptability of the equipment to different production batches and product models and has a wide range of applications.

[0032] Preparation and Usage: Place the glue applicator on the carrier plate 1 at the appropriate operating position, then connect the device to an external power source. The operator controls the device via the built-in switch of the liquid pump 22. After checking and cleaning impurities on the components, the touch screen can be placed to begin the glue applicator operation.

[0033] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, and can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method. Secondly, the specific connection methods of the signal acquisition circuit, power supply circuit, and data output interface of the sensor involved in this utility model all adopt mature standardized circuit designs in this field. These circuit connection schemes (such as the connection specifications of common I2C, SPI and other communication interfaces, or the basic topology of analog signal conditioning circuits) have been widely recorded in publicly available electronic technical manuals, sensor application guides or relevant industry standards, and belong to the existing public technologies that can be clearly known and implemented by those skilled in the art through conventional knowledge. Therefore, the inventive point of this utility model does not involve any substantial improvement to the internal circuit connection method of the sensor, and its specific circuit implementation details need not be elaborated.
