[0001] This utility model relates to the field of OLED / LCD / LED wearable display processing technology, specifically to a curing device for a narrow slit in the bezel of a 3D printed screen. Background Technology

[0002] In recent years, with increasing emphasis on health and a growing number of people enjoying sports, wearable display products have experienced explosive growth. However, the quality of wearable products on the market varies greatly. Waterproofing is a crucial performance indicator for evaluating the quality of a wearable product, and this waterproofing is primarily achieved through the curing of UV adhesive around the screen. The quality of this UV adhesive curing determines the overall waterproofing performance of the product.

[0003] Currently, most equipment on the market uses planar curing (a top-down direct curing method) to cure wearable products. However, due to the small size of wearable products, especially curved ones, poorly cured adhesive is easily left in the narrow gaps of the side bezels, greatly affecting product quality. To solve this process problem, this invention develops a five-sided composite curing lamp (four sides + top surface) structure, which solves the problem of difficult and poorly cured adhesive in the narrow gaps of wearable screen bezels. Utility Model Content

[0004] To address the problem of poor curing in narrow seams of wearable screen bezels that existing planar curing devices cannot solve, this invention provides a curing device for narrow seams of 3D printed screen bezels.

[0012] Furthermore, the light sources on the four sides are line light sources, while the light source on the top surface is a surface light source.

[0013] Furthermore, both the line light source and the surface light source are ultraviolet light sources.

[0014] Furthermore, the Y-axis power mechanism includes a Y-axis lead screw drive module or a Y-axis linear module.

[0015] Furthermore, the Y-axis lead screw transmission module includes a Y-axis motor and a lead screw driven and connected to the Y-axis motor. The lead screw is screwed to the Y-axis movable part to form a structure that converts rotational motion into linear motion.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1: The specific structure of this utility model is as follows:

[0032] Please refer to the appendix. Figure 1-5 This utility model discloses a curing device for a narrow slit in the frame of a 3D printed screen, comprising a gantry 5 arranged along the X-axis and a mounting plate fixed to the top beam of the gantry 5. The curing device also includes a lifting power source 6, an adhesive curing lamp 7, a Y-axis module 1, and a vacuum platform 2.

[0033] The lifting power source 6 is fixed to the mounting plate. The lifting power source 6 is driven by a connecting member, which performs a lifting action when driven. The lifting power source 6 is a lifting cylinder or a Z-axis linear module. In this embodiment, a lifting cylinder is preferred. The connecting member includes a connecting plate and two side plates. The connecting plate is connected to the driving part of the lifting cylinder, and the two side plates are perpendicular to the front side of the connecting plate and located on either side.

[0034] The glue curing lamp 7 is fixed to the connector; specifically, it is fixed horizontally between the two side plates. The glue curing lamp 7 has a multi-faceted light source, which generates a composite beam after being powered on. Figure 2-3 As shown, the main body of the glue curing lamp 7 is a square frame structure, with light sources provided on the four sides inside the frame opening and the top surface of the frame opening. The light sources on the four sides are line light sources 72, and the light source on the top surface is a surface light source 71. Both the line light source 72 and the surface light source 71 are ultraviolet light sources. The combined light beam formed by the line light source 72 and the surface light source 71 on the four sides makes the glue curing efficiency higher.

[0035] The four side line light sources 72 correspond to Figure 3 The four positions a, b, c, and d correspond to the area light source 71. Figure 3 The position of e.

[0036] The Y-axis module 1 is located below the gantry frame 5 and has a Y-axis power mechanism and a Y-axis movable part driven and connected to the Y-axis power mechanism. The Y-axis movable part moves along the Y-axis after being driven. The Y-axis power mechanism includes a Y-axis lead screw transmission module or a Y-axis linear module. The Y-axis lead screw transmission module includes a Y-axis motor and a lead screw driven and connected to the Y-axis motor. The lead screw is screwed to the Y-axis movable part to form a structure that converts rotational motion into linear motion.

[0037] The Y-axis movable part is equipped with a vacuum gauge 4 and multiple ball valves 3.

[0038] The vacuum platform 2 is installed on the Y-axis movable part. The platform 23 of the vacuum platform 2 is provided with multiple vacuum negative pressure zones. The moving path of the vacuum platform 2 can pass through the area irradiated by the composite beam.

[0039] The vacuum platform 2 is provided with multiple negative pressure connectors on one side, and the multiple negative pressure connectors are set one-to-one with the multiple vacuum negative pressure zones. Multiple ball valves 3 are connected one-to-one with the multiple negative pressure connectors through multiple air pipes.

[0040] like Figure 4-5As shown, the vacuum platform 2 includes a base plate 21, two vertical blocks arranged on the base plate 21, a negative pressure channel plate 22 mounted on the upper end of the two vertical blocks, and a negative pressure platform plate arranged on the upper end of the negative pressure channel plate 22. The upper end surface of the negative pressure platform plate is the platform surface 23.

[0041] Three ball valves 3 are installed on the side of the seat plate 21, and three negative pressure connectors are installed on the side of the negative pressure channel plate 22. The three ball valves 3 and the three negative pressure connectors are connected one-to-one through air pipes.

[0042] The negative pressure channel plate 22 has three negative pressure channels, each connected to one of three negative pressure connectors. For example... Figure 5 As shown, multiple vacuum negative pressure zones include a small vacuum negative pressure zone 23a, a medium vacuum negative pressure zone 23b, and a large vacuum negative pressure zone 23c, with each zone corresponding to different specifications of OLED / LCD / LED wearable displays.

[0043] Example 2:

[0044] The following describes the operating principle and process of the curing device for the narrow slit of the 3D printed screen bezel:

[0045] I. Pre-operation preparation stage:

[0046] ① Negative pressure system initialization: Check the status of vacuum gauge 4 and ball valve 3 on the Y-axis moving part: According to the size of the wearable screen frame to be cured, such as small / medium / large, open the ball valve of the corresponding vacuum negative pressure zone. For example, for small workpieces, the ball valve of "small area vacuum negative pressure zone 23a" is open, and the ball valves of other areas are closed. Start the negative pressure system and monitor the negative pressure value in real time through the vacuum gauge. It usually needs to reach -0.06 to -0.08 MPa to ensure that there is no leakage in the negative pressure channel and that the adsorption function of vacuum platform 2 is normal.

[0047] ②Inspection of curing lamp and power source: Turn on the power of the glue curing lamp 7 and check whether the five-sided light source, four-sided linear light source 72 and top surface light source 71 are emitting light normally. The ultraviolet light source should have no dark areas. Confirm the lifting power source 6. If the lifting cylinder is in the initial high position to avoid interference with the platform, the Y-axis movable part of the Y-axis module 1 is in the initial position outside the gantry 5.

[0048] II. Workpiece positioning and fixing stage:

[0049] ① Workpiece Placement: Precisely place the curved or flat workpiece of the OLED / LCD / LED wearable screen frame coated with UV glue into the vacuum negative pressure area corresponding to vacuum platform 2. For example, place small workpieces in area 23a. Ensure that the narrow slit of the workpiece frame faces the frame opening of the glue curing lamp to facilitate coverage by the five light sources.

[0050] ② Vacuum adsorption fixation: Confirm again that the corresponding ball valve is open, and use the negative pressure system to generate suction in the vacuum negative pressure zone, so that the workpiece is firmly adsorbed on the table 23; observe the value of vacuum gauge 4. If the negative pressure is stable and there is no significant drop, it means that the workpiece is fixed in place and there is no risk of loosening. Avoid displacement during the curing process that may cause accuracy deviation.

[0051] III. Curing Parameter Adjustment Stage:

[0052] ① Curing lamp height adjustment: Start the lifting power source 6. If it is a lifting cylinder, the connecting plate and side plate of the connecting part will be lowered through air pressure control, which will drive the glue curing lamp 7 to fall synchronously. According to the height of the workpiece, adjust the square frame opening of the curing lamp to the position where "the workpiece is completely inside the frame opening". Usually, the distance between the bottom surface of the frame opening and the top surface of the workpiece is 5-10mm, to ensure that the four-sided linear light source 72 can fit the narrow side gap and the top surface light source 71 can cover the top surface of the workpiece without any blind spots.

[0053] ②Y-axis movement parameter setting: According to the curing requirements of the UV adhesive, such as a curing time of 10-15 seconds, set the movement speed of Y-axis module 1: If the Y-axis power mechanism is a lead screw drive module, control the speed of the Y-axis motor so that the movement speed of the Y-axis moving part driven by the lead screw matches the curing time. For example, if the workpiece needs to stay in the beam area for 12 seconds, and the beam coverage length is 100 mm, then set the movement speed to 8.3 mm / s to ensure sufficient and uniform curing.

[0054] IV. Core Solidification and Operation Phase:

[0055] ①The Y-axis drives the workpiece into the curing zone and starts the Y-axis power mechanism: the Y-axis motor drives the lead screw to rotate, and the lead screw is screwed to the Y-axis movable part, converting the rotational motion into linear motion. The Y-axis movable part drives the vacuum platform 2 and the workpiece to move along the Y-axis to the curing lamp area below the gantry 5.

[0056] ② Synchronous curing from five light sources: When the workpiece enters the frame range of the adhesive curing lamp 7, the five light sources work synchronously. Four linear light sources 72, ultraviolet light: directly irradiate the narrow gaps on the side of the workpiece frame, specifically solving the curing dead corners on the side of curved workpieces and avoiding poor curing of adhesive in narrow gaps; top surface light source 71, ultraviolet light: vertically irradiates the top surface of the workpiece, ensuring synchronous curing of the UV adhesive on the top surface; the workpiece passes through the beam area at a uniform speed with the vacuum platform, and throughout the entire movement, the five-sided composite beam continuously covers the workpiece, achieving "all-round curing without dead corners".

[0057] ③ Curing process monitoring: Observe the value of vacuum gauge 4 in real time to ensure that the negative pressure is stable and the Y-axis movement is smooth. If the negative pressure drops or the movement is abnormal, stop the equipment immediately and check for loose workpieces or module failures to avoid scrapping uncured workpieces.

[0058] V. Post-curing repositioning and component removal stage:

[0059] ①Y-axis reset and curing lamp lifting: When the workpiece has completely passed through the curing lamp area and cured, the Y-axis module drives the Y-axis movable part to move the vacuum platform back to the initial position; at the same time, the lifting power source 6 drives the connecting part to rise, moving the curing lamp back to the initial high position to avoid interference when picking up the workpiece.

[0060] ② Workpiece removal and quality inspection: Close the negative pressure system, open the corresponding ball valve to release the vacuum negative pressure, and manually remove the cured workpiece; check the curing status of the UV adhesive at the narrow gap of the frame, such as whether there are bubbles or uncured residues. After confirming that it is qualified, proceed to the next process.

[0061] ③ Equipment Reset: Turn off the power to the glue curing lamp, reset all ball valves 3 to the closed state, return vacuum gauge 4 to zero, and restore the equipment to the initial standby state, waiting for the next batch of workpieces to be processed.

[0062] In summary, the curing device of this invention solves the problem of poor curing: the five light sources (four linear light sources + top surface light source) form a composite beam that fully covers the narrow gaps of the frame, avoiding dead corners in the curing of curved products.

[0063] This invention improves the versatility of the curing device: the multi-specification vacuum negative pressure zone is adapted to different sizes of OLED / LCD / LED wearable displays, eliminating the need for frequent tooling changes.

[0064] This utility model's curing device ensures curing accuracy: the Y-axis module precisely controls product movement, the lifting power source adjusts the height of the curing lamp, and vacuum adsorption fixation ensures accurate curing position and high efficiency.

[0065] This utility model's curing device optimizes ease of operation: a vacuum gauge monitors the negative pressure status in real time, and ball valves independently control each negative pressure zone, facilitating quick switching of product specifications.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
