Description

Technical Field

[0001] This utility model relates to the field of touch screen processing technology, and in particular to a dispensing device for touch screen processing. Background Technology

[0002] A touchscreen, also known as a touch panel or touch screen, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the haptic feedback system drives various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. As a latest computer input device, the touchscreen is a simple, convenient, and natural way of human-computer interaction. It gives multimedia a brand-new look and is a highly attractive new multimedia interactive device. It is mainly used in public information retrieval, industrial control, military command, video games, multimedia teaching, etc. However, the production process of touchscreens cannot be separated from dispensing equipment.

[0003] For example, Chinese Utility Model Patent Publication No. CN 211436835 U discloses a dispensing device for a mobile phone touchscreen production line, including a fixed bracket. A fixed movable frame is fixedly installed on the front end of the lower surface of the fixed bracket. A translation device is sleeved on the outside of the fixed movable frame. An air pipe is fixedly connected to the rear surface of the translation device, and a precision device is fixedly installed on the front surface of the translation device. A glue tube is fixedly connected to the front surface of the precision device. An adjustment device is fixedly connected to the right side of the glue tube, and a dispensing head is fixedly connected to the lower surface of the glue tube. The precision device can effectively solve the problem that dispensing equipment cannot dispense glue to touchscreens of different thicknesses. At the same time, the dispensing accuracy of the dispensing equipment can be improved by adjusting the height of the dispensing head through pointers and scales. The adjustment device can effectively control the glue flow rate in the glue tube, thereby avoiding glue waste.

[0004] However, the glue utilization effect is poor when the packaging edge is narrow, and there are more defects such as glue overflow and bubbles. Therefore, in order to change the dispensing angle during the dispensing operation and improve the dispensing quality when the packaging edge is narrow, a dispensing device for touch screen processing is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as excessive glue overflow and bubbles, when the packaging edge is narrow, by proposing a dispensing device for touch screen processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dispensing device for touch screen processing, comprising:

[0007] A dispensing base includes a moving mechanism and an angle adjustment seat. The angle adjustment seat is rotatably connected to the moving mechanism.

[0037] 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.

[0038] As mentioned in the background section, to address the shortcomings of excessive glue overflow and bubbles when dealing with narrow packaging edges, which fails to meet the high-quality requirements of touchscreens for narrow packaging edges, this application provides a dispensing device for touchscreen processing, including a dispensing base 1, a dispensing device 2, and a positioning mechanism 3. The dispensing base 1 includes a moving mechanism 11 and an angle adjustment seat 12, which is rotatably connected to the moving mechanism 11. An adjustment mechanism 13 is provided between the moving mechanism 11 and the angle adjustment seat 12, which can drive the angle adjustment seat 12 to rotate on the moving mechanism 11. The dispensing device 2 is located above the dispensing base 1, and the moving mechanism 11 can move horizontally below the dispensing device 2. The positioning mechanism 3 includes a positioning sensor 31 that moves with the dispensing base 1 and a fixed positioning sensor 32. The positioning sensor 31 and the positioning sensor 32 are signal-connected. When the positioning sensor 31 moves to a predetermined position, the dispensing device 2 dispenses glue onto the workpiece on the dispensing base 1.

[0039] See Figures 1-4In this way, when performing dispensing on the touchscreen, the angle between the touchscreen and the part to be dispensed can be adjusted, thereby changing the contact angle between the edge to be dispensed and the dispensing head. This allows more of the edge to be dispensed to be exposed under the dispensing head, enabling the adhesive to better penetrate the edge. This facilitates control over the amount of adhesive used and effectively reduces defects such as overflow and bubbles that are prone to occur on narrow dispensing edges, thus improving the dispensing quality of the touchscreen.

[0040] Furthermore, since the dispensing platform 122, which carries the dispensing operation, is rotatable, its relative position to the dispensing head of the dispensing device 2 will change when it rotates. Also, when dispensing touchscreens of different sizes and widths, the position of the edge to be dispensed relative to the dispensing head will change. Therefore, in this application, a movable moving mechanism 11 is provided to move the dispensing platform 122, so that the dispensing platform 122 can move with the touchscreen to the dispensing position of the dispensing device 2 for operation. This can adapt to the positional changes caused by the angle changes of the dispensing platform 122, and can also adapt to touchscreens of different sizes and widths.

[0041] In addition, by setting a positioning mechanism 3, this application can detect the movement position of the dispensing table 122. When the dispensing table 122 moves to the working position, the dispensing device 2 starts to dispense glue to the touch screen, which can realize a semi-automatic operation process.

[0042] The dispensing equipment for touch screen processing in this application embodiment can be applied to the dispensing operation in touch screen production. Specifically, it can be used for bonding touch screens to display panels, bonding protective glass to touch screens, and bonding frames to touch screens, and is not limited to touch screens of displays.

[0043] See Figures 2-5 The dispensing base 1 includes a moving mechanism 11, an angle adjustment seat 12, an adjustment mechanism 13, and a moving drive component 14. The moving mechanism 11 can move on the frame. The fixed end of the moving drive component 14 is fixedly installed on the frame. The telescopic end of the moving drive component 14 is fixedly connected to the moving mechanism 11. The angle adjustment seat 12 is rotatably connected to the moving mechanism 11. The adjustment mechanism 13 is disposed between the moving mechanism 11 and the angle adjustment seat 12 and can adjust the angle between the moving mechanism 11 and the angle adjustment seat 12.

[0044] The adjustment mechanism 13 is a structure that can rotate an object around an axis by a certain angle and then fix it at the required angle. It includes at least an adjustment follower 131 and an adjustment drive 132. The adjustment drive 132 is mounted on the moving mechanism 11 and is used to drive the adjustment follower 131 to rotate. The angle adjustment seat 12 is a structure that can mount and place a touch screen to be glued. It includes at least a glue dispensing table 122 for mounting the touch screen.

[0045] Therefore, the angle of the dispensing table 122 can be adjusted by the adjustment mechanism 13, so that the dispensing edge line between the touch screen to be dispensed and the part to be dispensed can be exposed, which facilitates the dispensing operation on the touch screen.

[0046] In one embodiment, specifically, the adjusting driven member 131 includes a main shaft 1311 fixed on a rotating seat 121, and a worm gear 1312 fixedly mounted on the main shaft 1311; the adjusting driving member 132 includes a worm 1321, which is rotatably mounted on a movable seat 111. The worm 1321 meshes with the worm gear 1312. A knob 1322 is fixedly mounted on one end of the worm 1321, and the knob 1322 extends outside the movable seat 111 for easy rotation by the operator. When the operator rotates the knob 1322, the main shaft 1311 is driven to rotate through the meshing of the worm 1321 and the worm gear 1312, thereby changing the angle of the rotating seat 121 and adjusting the angle of the dispensing table 122 so that the touch screen to be dispensed can be tilted, exposing the edge line to be dispensed.

[0047] Optionally, the adjusting driven member 131 and the adjusting driving member 132 can be worm gears, hydraulic telescopic mechanisms, telescopic electric cylinders, or other structures that enable the adjusting driving member 132 to drive the adjusting driven member 131 to rotate a certain angle and then fix it at the required angle. The specific structure is not limited.

[0048] In some embodiments, the angle adjustment seat 12 includes a rotating seat 121 and a dispensing platform 122, the dispensing platform 122 being fixedly connected above the rotating seat 121 and the adjustment follower 131 being fixedly connected below the rotating seat 121; the moving mechanism 11 includes a moving seat 111, on which a bearing seat 112 is fixedly disposed, and the adjustment follower 131 being rotatably connected to the bearing seat 112.

[0049] The dispensing device 2 includes a dispensing frame 21 for movement and a dispensing tube 22 for dispensing. The dispensing frame 21 is slidably connected to the frame 4, and the dispensing tube 22 is movably mounted on the dispensing frame 21.

[0050] In some embodiments, the dispensing frame 21 can move on the frame 4, and its moving direction is perpendicular to the moving direction of the moving mechanism 11. When the dispensing tube 22 can move up and down on the dispensing frame 21, it performs dispensing operations on the touch screen. The dispensing device 2 adopts a common dispensing method, that is, the dispensing frame 21 moves with the dispensing tube 22. In related technologies, after the dispensing tube 22 moves above the workpiece to be dispensed, the dispensing tube 22 descends to dispense glue onto the workpiece.

[0051] Positioning sensor 1 31 can be moved to a fixed position on the dispensing table 122, and positioning sensor 2 32 is fixedly installed on the frame 4; positioning sensor 2 32 and the dispensing head moving plane of dispensing device 2 are on the same plane.

[0052] In one embodiment, a sliding groove is provided on the dispensing table 122, and the positioning sensor 31 moves on the dispensing table 122 through the sliding groove and the movable slider. When the operator moves the positioning sensor 31 to a fixed position by hand, the positioning sensor 31 remains stationary at that position.

[0053] It also includes a control unit, which is communicatively connected to the positioning mechanism 3 and controlled by the moving drive 14; positioning sensor 1 31 and positioning sensor 2 32 are used to detect the distance between the dispensing base 1 and the dispensing device 2. When positioning sensor 2 32 moves to the designated position, the control unit causes the moving drive 14 to stop moving.

[0054] In practical applications, the operator first moves the positioning sensor 31 to the position of the dispensing edge according to the size of the touchscreen, referring to the attached diagram. Figure 4 In one specific embodiment, the component 5 to be dispensed includes a touch screen 51 and a display panel 52, with a dispensing edge line 53 formed between the touch screen 51 and the display panel 52. The operator moves the positioning sensor 31 to the straight line position of the dispensing edge line 53, so that the positioning sensor 31 and the dispensing edge line 53 are in the same straight line. At this time, the device is started, and the moving drive 14 drives the dispensing base 1 to move towards the dispensing device 2. When the positioning sensor 32 detects that the positioning sensor 31 is directly below, that is, at this time the dispensing edge line 53 and the dispensing head are in the same vertical plane, the control unit receives the position information of the positioning mechanism 3, and the control unit brakes the moving drive 14 to position the dispensing base 1 on the frame 4. At this time, the dispensing device 2 can perform dispensing operation on the touch screen 51, which can ensure that the dispensing head and the dispensing edge line 53 are in a mutually cooperating position, ensuring the accuracy of dispensing.

[0055] Optionally, the control unit can be a PLC controller, microprocessor, or other processing device, and there are no specific limitations.

[0056] Optionally, positioning sensor 31 and positioning sensor 32 can be laser sensors, ultrasonic sensors, or other position sensors capable of positioning each other.

[0057] To better understand the working process of the dispensing device in this application embodiment, a specific embodiment is described below: First, the operator moves the positioning sensor 31 to the position of the dispensing edge 53 according to the size of the touch screen 51. The operator adjusts the angle of the dispensing table 122 through the adjustment mechanism 13 so that the dispensing edge 53 can be exposed. Then, several parts to be dispensed 5 can be installed on the dispensing table 122. After the device is started, the moving drive 14 drives the moving mechanism 11 to move, so that the dispensing table 122 moves along with it and thus moves the parts to be dispensed 5 toward the dispensing device 2. When the positioning sensor 31 and the positioning sensor 32 are in the same vertical position, the control unit responds to the position signal of the positioning mechanism 3 and stops the extension and retraction of the moving drive 14 to fix the dispensing base 1 in the working position. Then, the dispensing device 2 moves back and forth to perform dispensing operations on each part to be dispensed 5 in sequence. After dispensing a part to be dispensed 5 is completed, the operator can remove it and replace it with the next part to be dispensed 5 for dispensing.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
