Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a narrow bezel dispensing device for full-screen displays. Background Technology

[0002] The manufacturing process of a full-screen mobile phone is a highly precise manufacturing process. Its core lies in maximizing the display area through technologies such as irregular cutting and under-display cameras to pursue the ultimate screen-to-body ratio. Among this series of complex processes, the adhesive application process for the narrow bezel of the full-screen display is particularly critical. It is mainly responsible for high-precision sealing and structural fixation within the extremely narrow bezel area. This process not only effectively prevents screen light leakage and improves overall strength, but also ensures that internal components are protected from moisture and dust. It is an important guarantee for achieving the visual effect of "narrow bezels on all four sides" and reliable quality.

[0003] However, traditional full-screen narrow bezel dispensing equipment is usually more complex in structure and relatively expensive. Moreover, the dispensing head often adopts a rigid structure with a fixed height. It is not very adaptable to the slight warping inherent in mobile phone screen components or uneven working surface height caused by assembly tolerances, and the dispensing needle is prone to clogging due to pressure changes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a narrow bezel dispensing device for full-screen displays. It features a simple structure, low cost, and the ability to automatically adapt to and compensate for height differences on the workpiece surface during dispensing. This solves the problems of high cost due to complex structure and cumbersome debugging of traditional narrow bezel dispensing devices for full-screen displays, as well as the issues of uneven dispensing, glue breakage, or even scratching of products when encountering height differences on the workpiece surface due to rigid contact.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a narrow bezel dispensing device for full-screen displays, comprising a support frame, an adjustment component disposed on the surface of the support frame, a floating dispensing component disposed on the surface of the adjustment component, and a conveying component disposed below the adjustment component;

[0006] The adjustment assembly includes a motor fixedly connected to the top of the support frame. A drive shaft is fixedly installed at the output end of the motor. Two support plates are fixedly installed on the inner top wall of the support frame. A first slide rail is fixedly installed on the surface of each of the two support plates. A first sliding block is slidably connected inside each of the two first slide rails. A frame is fixedly installed on the opposite side of the two first sliding blocks. Two second slide rails are fixedly installed on the inner wall of the frame. A second sliding block is slidably connected inside each of the two second slide rails. A sliding plate is fixedly installed on the opposite side of the two second sliding blocks. An installation groove is opened inside the sliding plate. An eccentric wheel is fixedly installed at the end of the drive shaft away from the motor. The outer wall of the eccentric wheel fits against the inner wall of the installation groove.

[0007] Furthermore, the floating dispensing assembly includes a mounting box fixedly connected to the top of the sliding plate. Four springs are fixedly installed on the top wall of the mounting box. A connecting block is fixedly connected to one end of each spring away from the top wall of the mounting box. A dispensing device is fixedly installed on the outer wall of the connecting block. A dispensing tube is connected to the top of the connecting block.

[0008] Furthermore, the surface of the mounting box has an opening, and the connecting block extends from the inside of the mounting box to the top through the opening.

[0009] Furthermore, the conveying assembly includes a conveyor belt, with support legs fixedly installed on the outer wall of the conveyor belt, and a number of mobile phone frames placed on the surface of the conveyor belt.

[0010] Furthermore, the conveyor belt is positioned below the sliding plate, and the support leg is positioned inside the support frame.

[0013] Furthermore, a fixing frame is fixedly installed on the inner top wall of the support frame, and a sleeve is fixedly installed on the inner wall of the fixing frame. The inner wall of the sleeve is rotatably connected to the surface of the transmission shaft.

[0014] Compared with the prior art, this utility model provides a narrow bezel dispensing device for full-screen displays, which has the following beneficial effects:

[0015] 1. This narrow bezel dispensing device for full-screen displays uses a motor to drive an eccentric wheel to rotate. The eccentric wheel's contact motion within the mounting groove of the sliding plate converts the rotation into a combined horizontal and vertical motion of the sliding plate, thereby driving the dispensing device to achieve precise trajectory control and quickly dispensing adhesive onto the surface of the phone's frame. This design consists of only basic components and does not require a complex control system, achieving significant advantages such as simple structure and low cost.

[0016] 2. This narrow-bezel dispensing device for full-screen displays, when the dispensing nozzle contacts the workpiece surface at the start of dispensing, can rely on the compression and rebound of the spring to ensure that the dispensing nozzle always fits tightly against the workpiece. This design realizes automatic adaptation and compensation for the height difference of the workpiece surface during the dispensing process, effectively ensuring the uniformity of the dispensing trajectory and the sealing quality.

[0023] 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.

[0024] Please see Figures 1 to 5 This embodiment of a narrow bezel dispensing device for full-screen displays includes a support frame 1, an adjustment component 2 on the surface of the support frame 1, a floating dispensing component 3 on the surface of the adjustment component 2, and a conveying component 4 below the adjustment component 2.

[0025] Specifically, the adjustment assembly 2 includes a motor 5 fixedly connected to the top of the support frame 1. A transmission shaft 6 is fixedly installed at the output end of the motor 5. Two support plates 7 are fixedly installed on the inner top wall of the support frame 1. A first slide rail 8 is fixedly installed on the surface of each of the two support plates 7. A first sliding block is slidably connected inside each of the two first slide rails 8. A frame 9 is fixedly installed on the opposite side of the two first sliding blocks. Two second slide rails 10 are fixedly installed on the inner wall of the frame 9. A second sliding block is slidably connected inside each of the two second slide rails 10. A sliding plate 11 is fixedly installed on the opposite side of the two second sliding blocks. An installation groove is opened inside the sliding plate 11. An eccentric wheel 12 is fixedly installed at the end of the transmission shaft 6 away from the motor 5. The outer wall of the eccentric wheel 12 is in contact with the inner wall of the installation groove.

[0026] Among them, the motor 5 drives the transmission shaft 6 and the eccentric wheel 12 to rotate. The rotational motion is converted into the sliding motion of the sliding plate 11 along the second slide rail 10 and the sliding motion of the frame 9 along the first slide rail 8 by the contact motion of the eccentric wheel 12 in the mounting groove of the sliding plate 11. This realizes the composite motion of the sliding plate 11 in the horizontal and vertical directions, so as to drive the floating dispensing assembly 3 to move along a predetermined trajectory.

[0027] Please see Figure 1 and Figure 4 In this embodiment, the floating dispensing assembly 3 includes a mounting box 13 fixedly connected to the top of the sliding plate 11. Four springs 14 are fixedly installed on the top wall of the mounting box 13. A connecting block 15 is fixedly connected to one end of the four springs 14 away from the top wall of the mounting box 13. A dispensing device 16 is fixedly installed on the outer wall of the connecting block 15. A glue supply tube 21 is connected to the top of the connecting block 15.

[0028] When the dispensing device 16 contacts the surface height difference of the mobile phone frame 19, the spring 14 is compressed and undergoes elastic deformation, causing the connecting block 15 to float up and down within the mounting box 13. This allows the dispensing device 16 to adapt to the undulations of the mobile phone frame 19 surface, ensuring that the dispensing device 16 always maintains close contact with the edge of the mobile phone frame 19, thereby achieving uniform and precise narrow bezel dispensing.

[0029] Please see Figure 4 In this embodiment, the surface of the mounting box 13 has an opening, and the connecting block 15 extends from the inside of the mounting box 13 to the top through the opening.

[0030] Please see Figure 1 In this embodiment, the conveying component 4 includes a conveyor belt 17, a support leg 18 is fixedly installed on the outer wall of the conveyor belt 17, and a number of mobile phone frames 19 are placed on the surface of the conveyor belt 17.

[0031] The conveyor belt 17 is stably supported by the support legs 18. The continuous operation of the conveyor belt 17 transports multiple mobile phone frames 19 placed on its surface to the predetermined working position of the dispensing machine 16 in sequence, so as to realize the automated and continuous dispensing operation of the workpiece.

[0032] Please see Figure 1 and Figure 3 In this embodiment, the conveyor belt 17 is disposed below the sliding plate 11, and the support leg 18 is disposed inside the support frame 1.

[0033] Please see Figure 1 and Figure 4 In this embodiment, the dispensing device 16 is positioned above the mobile phone frame 19, and a rubber layer is provided at the opening of the mounting box 13.

[0034] The rubber layer not only effectively reduces friction, ensures smooth floating, and reduces component wear when the connecting block 15 floats up and down, but also prevents dust and other impurities from entering the mounting box 13, ensuring the normal operation of precision components such as the spring 14 and the cleanliness and stability of the dispensing process.

[0035] Please see Figure 2 In this embodiment, a wear-resistant bushing is fixedly installed on the inner wall of the mounting groove, and the outer wall of the eccentric wheel 12 is in contact with the inner wall of the wear-resistant bushing.

[0036] Among them, the wear-resistant bushing can effectively withstand and disperse the friction and impact transmitted by the rotation of the eccentric wheel 12, thereby significantly reducing the wear of the mounting groove itself.

[0037] Please see Figure 1 In this embodiment, a fixed frame is fixedly installed on the inner top wall of the support frame 1, and a sleeve 20 is fixedly installed on the inner wall of the fixed frame. The inner wall of the sleeve 20 is rotatably connected to the surface of the transmission shaft 6.

[0038] Among them, the sleeve 20 provides a stable and reliable intermediate support point for the drive shaft 6, which can effectively constrain the radial runout and deflection deformation of the drive shaft 6 when rotating at high speed, thereby ensuring the accurate and stable running trajectory of the eccentric wheel 12, and ultimately ensuring the accuracy of the entire dispensing trajectory and the smoothness of equipment operation.

[0039] The working principle of the above embodiments is as follows:

[0040] The motor 5 drives the transmission shaft 6 and the eccentric wheel 12 to rotate. The eccentric wheel 12 is in contact with the mounting groove of the sliding plate 11, which converts the rotational motion into a compound motion of the sliding plate 11 along the second slide rail 10 and the frame 9 along the first slide rail 8 in the horizontal and vertical directions. This drives the dispensing device 16 to perform a dispensing operation along a predetermined trajectory. At the same time, when the dispensing device 16 contacts the surface of the mobile phone frame 19, the spring 14 allows the connecting block 15 and the dispensing device 16 to float with the undulation of the workpiece surface, ensuring that the dispensing device 16 is always in close contact with the edge of the mobile phone frame 19. Finally, the fast and precise narrow bezel dispensing operation of the mobile phone frame 19 is completed.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
