[0029] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0030] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Embodiment 1: Figures 1 to 7 As shown, the LED lamp bead packaging structure of the present application includes a base 10, a first driving component 20, a second driving component 30, a third driving component 40, a sliding block 50, a glue gun 60, a power assembly and a control unit;

[0033] The number of the first driving components 20 is two, and the two first driving components 20 are vertically arranged on the base 10 .

[0034] The first driving component 20 may be a telescopic cylinder.

[0035] The top ends of the two first driving components 20 are respectively connected to the two ends of the second driving component 30, and the second driving component 30 is arranged horizontally.

[0036] The third driving member 40 is slidably disposed on the second driving member 30 .

[0037] The third driving member 40 is disposed horizontally, and the third driving member 40 and the second driving member 30 are disposed perpendicularly.

[0038] The third driving component 40 is located above the base 10 .

[0039] It should be noted that the second driving component 30 and the third driving component 40 can be slidably arranged together via an electric slide rail; the electric slide rail is a common structure in the prior art and will not be described in detail here.

[0040] The sliding block 50 is horizontally slidably disposed on the third driving component 40 , and the sliding block 50 is located above the base 10 .

[0041] It should be noted that the sliding block 50 and the third driving component 40 can be slidably arranged together via an electric slide rail; the electric slide rail is a common structure in the prior art and will not be described in detail here.

[0042] The glue gun 60 is disposed on the sliding block 50 .

[0043] It should be noted that the glue gun 60 can be snap-connected to the sliding block 50 or can be threadedly connected to the sliding block 50 . The specific installation method is selected according to actual needs and will not be described in detail here.

[0044] Further, such as Figure 1 As shown, a movable plate 11 is movably arranged on the base 10, and a translation driving track is arranged between the base 10 and the movable plate 11, and the translation driving track is used to drive the base 10 to perform lateral and longitudinal translation on a horizontal plane.

[0045] It should be noted that the translational driving track is a common structure in the prior art and will not be described in detail here.

[0046] The power assembly is used to provide energy for the operation of the packaging structure, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of the various components of the packaging structure, preferably a programmable logic controller; both are prior arts and will not be described in detail here.

[0047] It should be noted that there may be multiple sliding blocks 50 , and multiple glue guns 60 may be used to dispense glue at the same time.

[0048] It can be understood that the vertical movement of the second driving component 30 is realized by operating the first driving component 20 through the control unit; the horizontal sliding of the second driving component 30 and the third driving component 40, in conjunction with the sliding block 50, can realize the precise positioning of the glue gun 60 in three-dimensional space; when the glue gun 60 is positioned at the appropriate position, the LED lamp beads can be started to be dispensed and packaged; by adjusting the position of the sliding block 50 through the control unit, the spacing between the glue guns 60 (if there are multiple sliding blocks 50) can be changed to accommodate LED lamp bead brackets of different sizes; the movable disk 11 and the translational drive track allow the operator to move the entire base 10 as needed to facilitate the packaging of LED lamp beads in different positions.

[0049] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0050] 1. Multi-dimensional motion control makes the positioning of the glue gun 60 more precise, improving the quality of packaging;

[0051] 2. The arrangement of the sliding block 50 and the electric slide rail provides a flexible operation mode, and cooperates with the movable plate 11 to quickly adapt to different packaging requirements.

[0052] Embodiment 2: After a long period of dispensing and packaging, a portion of packaging glue will remain at the glue outlet of the glue gun 60 in the above embodiment. If the time is too long, this portion of the residual packaging glue may solidify, resulting in defects in the subsequent dispensing and packaging process. The embodiment of the present application is optimized based on the above embodiment.

[0053] like Figures 1 to 4 As shown, the LED lamp bead packaging structure of the present application further includes a glue removal component 70 , which is disposed on the base 10 , and the glue removal component 70 is staggered with the movable plate 11 .

[0054] It should be noted that the glue removal assembly 70 will not affect the translation of the movable plate 11 , and the glue gun 60 can be moved above the glue removal assembly 70 .

[0055] The adhesive removal assembly 70 includes a housing 71 and a plurality of cone-shaped cloths 72 .

[0056] The shell 71 is a hollow cube, and a plurality of upper openings are formed at the top of the shell 71 . The number of the upper openings is the same as that of the cone cloths 72 and they correspond one to one.

[0057] It should be noted that the number of the plurality of cone cloths 72 can be 3, 4, 5, 6, 7 cone cloths 72, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0058] The conical cloth 72 is located in the shell 71 , and the conical cloth 72 is a conical bag structure with a larger upper portion and a smaller lower portion.

[0059] The top of the conical cloth 72 is open, and the top of the conical cloth 72 is sleeved on the upper opening of the shell 71 .

[0060] It should be noted that the top of the conical cloth 72 can be mounted on the upper opening of the shell 71 by means of Velcro or snap-fit, so that the conical cloth 72 can be replaced.

[0061] The conical cloth 72 is made of dust-free cloth.

[0062] It can be understood that during the LED lamp bead packaging process, the glue gun 60 performs glue dispensing operations according to a predetermined procedure; after a period of glue dispensing operations, the glue gun 60 moves to the top of the glue removal component 70, and the glue outlet of the glue gun 60 is aligned with the top opening of the conical cloth 72. The control unit drives the glue gun 60 to move up and down slightly so that the glue outlet contacts the conical cloth 72. The conical structure of the conical cloth 72 helps to remove residual glue from the glue outlet; when the conical cloth 72 absorbs enough glue and becomes saturated, the conical cloth 72 can be easily replaced to ensure the glue removal effect.

[0063] It should be noted that there are multiple conical cloths 72. During the degumming process, the glue gun 60 can be inserted into any one of the conical cloths 72 or multiple conical cloths 72 for degumming. At the same time, the number of degumming times for each conical cloth 72 can be limited through the program. The conical cloth 72 that reaches the degumming times threshold will no longer be degummed. When multiple conical cloths 72 reach the degumming times threshold, the relevant personnel can be reminded to replace them.

[0064] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0065] 1. By timely removing the residual glue at the glue outlet, packaging defects caused by glue curing are avoided and packaging quality is improved;

[0066] 2. Regularly cleaning the glue outlet can prevent the glue from solidifying and blocking the glue outlet, thus extending the service life of the glue gun 60;

[0067] 3. The replaceable setting of the cone cloth 72 makes maintenance easier and faster, reducing downtime;

[0068] 4. Reduce downtime and rework caused by glue residue and curing, and improve production efficiency.

[0069] Embodiment 3: In the above embodiment, during the glue removal process, the glue gun 60 may fail to sufficiently contact the glue removal port of the glue gun 60 with the inner wall of the upper part of the conical cloth 72 due to the large inner diameter of the conical cloth 72. The embodiment of the present application is optimized based on the above embodiment.

[0070] The material of the tapered cloth 72 in this embodiment may be elastic rubber.

[0071] It should be noted that the elastic coefficient of the tapered cloth 72 is selected according to actual needs and will not be described in detail here.

[0072] like Figures 4 to 6 As shown, a plurality of lining dust-free cloths 73 are arranged inside the conical cloth 72 .

[0073] It should be noted that the plurality of liner dust-free cloths 73 may be 3, 4, 5, 6, 7 liner dust-free cloths 73, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0074] The liner dust-free cloth 73 is a tapered tube structure with a larger upper portion and a smaller lower portion as a whole, and the inner diameters of the upper ends and the lower ends of the plurality of liner dust-free cloths 73 decrease sequentially from top to bottom.

[0075] The plurality of liner dust-free cloths 73 are sequentially nested together from top to bottom. Among two adjacent liner dust-free cloths 73 , the inner diameter of the lower end of the liner dust-free cloth 73 located on the upper side is larger than the inner diameter of the upper end of the liner dust-free cloth 73 located on the lower side.

[0076] The outer ring of the top end of the lining dust-free cloth 73 is arranged in a ring shape on the inner wall of the conical cloth 72 .

[0077] It should be noted that the bottom end of the liner dust-free cloth 73 not located at the bottom is in contact with the inner wall of the liner dust-free cloth 73 located therebelow, and the bottom end of the liner dust-free cloth 73 located at the bottom is in contact with the inner wall of the conical cloth 72 .

[0078] Further, such as Figure 7 As shown, the outer wall of the conical cloth 72 is sleeved with a plurality of elastic rings 74 from top to bottom.

[0079] The elastic ring 74 may be made of elastic rubber.

[0080] It should be noted that the plurality of elastic rings 74 may be 3, 4, 5, 6, 7 elastic rings 74, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0081] It should be noted that the elastic coefficient of the elastic ring 74 is greater than the elastic coefficient of the conical cloth 72, and the diameter of the elastic ring 74 in the initial state is smaller than the inner diameter of the corresponding position on the conical cloth 72, so that the conical cloth 72 is restricted by the elastic ring 74; the elastic coefficient of the elastic ring 74 and the diameter of each elastic ring 74 are selected according to actual needs and will not be described in detail here.

[0082] It can be understood that when glue removal is required, the glue gun 60 is moved above the glue removal component 70; the glue outlet of the glue gun 60 contacts the conical cloth 72, and due to the elastic rubber material of the conical cloth 72 and the conical tube structure of the lining dust-free cloth 73, the glue outlet contacts the inner wall of the conical cloth 72 more fully; during the cleaning process, the elastic ring 74 limits the excessive expansion of the conical cloth 72, maintains its shape and stability, and provides appropriate elastic pressure to assist cleaning; when the lining dust-free cloth 73 absorbs enough glue, it can be replaced separately without replacing the entire conical cloth 72, thereby reducing maintenance costs.

[0083] It should be noted that when the glue gun 60 is pulled out of the conical cloth 72, the bottom of the lining dust-free cloth 73 will flexibly scrape the glue removal port of the glue gun 60. At this time, part of the packaging glue will enter the outer circle of the lining dust-free cloth 73, thereby improving the utilization rate of the lining dust-free cloth 73 and the glue removal port on the glue gun 60 can be cleaned more thoroughly.

[0084] When the LED lamp bead packaging structure of the embodiment of the present application is actually operated, the steps are as follows:

[0085] S1: Start the packaging structure, ensure that all components are in a standby state, and position the glue gun 60 to the working starting position;

[0086] S2: Perform glue dispensing and packaging, control the glue gun 60 to perform glue dispensing operation on the LED lamp bead bracket according to the preset program, and monitor the glue dispensing process to ensure the packaging quality;

[0087] S3: After the glue dispensing is completed, the glue gun 60 is moved to the top of the glue removal component 70, so that the glue outlet of the glue gun 60 is aligned with the opening of the conical cloth 72; the glue gun 60 is driven to move up and down, so that the glue outlet is in full contact with the conical cloth 72 and its lining dust-free cloth 73, and the residual glue at the glue outlet is removed by the lining dust-free cloth 73;

[0088] S4: After cleaning, check whether the glue outlet of the glue gun 60 is clean. If necessary, replace the lining dust-free cloth 73 to maintain the glue removal effect. After confirmation, the glue gun 60 returns to the working starting position to prepare for the next round of glue dispensing and packaging operations.

[0089] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0090] 1. The setting of the elastic rubber material and the inner lining dust-free cloth 73 improves the cleaning efficiency of the glue outlet of the glue gun 60 and reduces the possibility of residual glue;

[0091] 2. The adjustability of the inner lining dust-free cloth 73 enables the glue removal assembly 70 to adapt to glue guns 60 of different sizes, thereby improving the versatility of the equipment;

[0092] 3. Through more effective cleaning, the maintenance frequency of glue gun 60 is reduced and its service life is extended;

[0093] 4. The replaceability of the liner dust-free cloth 73 reduces the overall maintenance cost because only the consumables need to be replaced instead of the entire component.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
