Description

Technical Field

[0001] This utility model relates to the field of adhesive fitting technology, and in particular to an LCM film-coated adhesive fitting. Background Technology

[0002] All LCM projects require finished product lamination. As customers have increasingly higher requirements for product quality, the standards for protective film bubbles are becoming more stringent, and the requirements for adhesion effect are becoming more rigorous.

[0003] In existing technologies, the current LCM coating process usually uses an acrylic squeegee to smooth the film, but because the edges of acrylic are hard, it is easy to scratch the protective film; the squeegees used in the current LCM coating process do not have a fixed storage location and are easy to lose, and cannot be adsorbed on the worktable, so they are easy to be accidentally touched and damaged; the current LCM coating process is usually done manually, and manual application often results in fingerprints on the surface of the LCM module and the protective film. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an LCM film-attaching fixture, which can effectively solve the shortcomings of the prior art.

[0005] An LCM coating application fixture includes a substrate, a scraper assembly, and a placement position on the top of the substrate for placing an LCM module. The placement position has several positioning holes and multiple positioning elements surrounding the LCM module. The positioning elements are threaded onto the positioning holes. The scraper assembly includes a scraper structure, a filling layer wrapped around the outside of the scraper structure, and buffer layers wrapped around both ends of the filling layer to reduce friction. An adsorption structure for adsorbing the substrate is located at the center of the scraper structure. A duct interface for connecting an air pump is located on one side of the substrate, and the duct interface connects to the positioning holes. A retractable corrugated pipe for adsorbing the LCM coating is located on the side of the substrate adjacent to the duct interface and communicates with the duct interface. A nozzle structure for controlling airflow is detachably installed at the end of the corrugated pipe away from the substrate.

[0006] Furthermore, a scraper storage position for storing the scraper assembly is also provided on the top of the substrate.

[0007] Furthermore, grooves are provided at both ends of the scraper storage position to facilitate the placement and removal of the scraper assembly.

[0008] Furthermore, a label attachment position for attaching the LCM module label is provided on the top of the substrate, and the label attachment position is located on the side of the placement position away from the scraper storage position.

[0009] Furthermore, the substrate is made of ferrous metal, and the adsorption structure is a magnet.

[0010] Furthermore, the scraper structure is made of PMMA.

[0011] Furthermore, the material of the insulating layer is polyester fiber.

[0012] Furthermore, the buffer layer is made of polytetrafluoroethylene.

[0013] The beneficial effects of this utility model are as follows: The operator connects the air pump to the air duct interface and starts the air pump, adjusting it to jet mode. The air ejected through the corrugated pipe and positioning holes removes dust from the placement area, preventing dust and impurities from entering between the film and the screen during subsequent LCM lamination. After dust removal from the placement area, the air pump is turned off, and the LCM module is placed on the placement area and fixed using multiple positioning components around it. This improves the placement accuracy of the LCM module and enhances its stability during lamination. After fixing the LCM module, the corresponding nozzle structure is selected according to the required lamination and installed on the corrugated pipe. The air pump is then started and adjusted to suction mode. The nozzle structure adsorbs the side of the lamination furthest from the release paper and moves the lamination to the LCM. At the top of the M module, peel off the release paper and attach the film to the LCM module. Simultaneously, the positioning holes will vacuum the area around the LCM module to prevent fingerprints from getting on the surface of the LCM module and the protective film during manual application. After the LCM film is attached to the LCM module, turn off the air pump and smooth the film using the squeegee structure. An isolation layer is wrapped around the outside of the squeegee structure to prevent scratches on the LCM film during smoothing. Buffer layers are wrapped at both ends of the isolation layer to reduce friction between the squeegee structure and the protective film during smoothing, preventing dirt and scratches. During the LCM film application process, the squeegee structure can be adhered to the substrate using an adsorption structure to prevent accidental damage. Attached Figure Description

[0020] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1 to 3 The LCM coating and attaching fixture in this embodiment of the present invention includes a substrate 10, a scraper assembly 20, and a placement position 11 disposed on the top of the substrate 10 for placing an LCM module. The placement position 11 has a plurality of positioning holes 12 and a plurality of positioning elements 13 disposed around the LCM module. The positioning elements 13 are threadedly connected to the positioning holes 12. The scraper assembly 20 includes a scraper structure 21, an isolation layer 22 wrapped around the outside of the scraper structure 21 for filling, and an isolation layer 22 wrapped in the width direction of the isolation layer 22. The buffer layers 23 at both ends are used to reduce friction. An adsorption structure 24 for adsorbing the substrate 10 is provided in the center of the scraper structure 21. A duct interface 14 for connecting an air pump is provided on one side of the substrate 10. The duct interface 14 is connected to the positioning hole 12. A retractable corrugated pipe 15 for adsorbing LCM coating is provided on the side of the substrate 10 adjacent to the duct interface 14 and is connected to the duct interface. A nozzle structure 16 for controlling the air volume is detachably provided at the end of the corrugated pipe 15 away from the substrate 10.

[0025] Furthermore, the substrate 10 is made of iron metal, and the adsorption structure 24 is a magnet.

[0026] Furthermore, the scraper structure 21 is made of PMMA.

[0027] Furthermore, the material of the isolation layer 22 is polyester fiber.

[0028] Furthermore, the buffer layer 23 is made of polytetrafluoroethylene.

[0029] Understandably, the operator connects the air pump to the duct interface 14 and starts the air pump, adjusting it to jet mode. This allows the air ejected from the corrugated pipe 15 and the positioning hole 12 to remove dust from the placement position 11, preventing dust and impurities from entering between the film and the screen during subsequent LCM lamination. After cleaning the placement position 11, the air pump is turned off, and the LCM module is placed on the placement position 11 and fixed using the multiple positioning elements 13 surrounding the LCM module. This improves the placement accuracy of the LCM module and enhances its stability during lamination. After fixing the LCM module, the corresponding nozzle structure 16 is selected according to the required lamination and installed on the corrugated pipe 15. The air pump is then started and adjusted to suction mode. The nozzle structure 16 adsorbs the side of the LCM lamination away from the release paper and moves the LCM lamination to the top of the LCM module. At this point, the release paper is removed and the LCM film is attached to the LCM module. Simultaneously, the positioning hole 12 vacuums the area around the LCM module, preventing fingerprints from accumulating on the surface of the LCM module and protective film during manual application. After the LCM film is attached to the LCM module, the air pump is turned off, and the LCM film is smoothed using the scraper structure 21. The isolation layer 22 is wrapped around the outside of the scraper structure 21, preventing scratches on the LCM film during the smoothing process. The buffer layer 23 is wrapped around both ends of the isolation layer 22 in the width direction, reducing friction between the scraper structure 21 and the protective film during smoothing, preventing dirt and scratches. During the LCM film application process, the scraper structure 21 can be adsorbed onto the substrate 10 by the adsorption structure 24, preventing accidental damage.

[0030] Furthermore, a scraper storage position 17 for storing the scraper assembly 20 is also provided on the top of the substrate 10.

[0031] It is understandable that by providing a scraper storage position 17 for storing the scraper assembly 20 on the top of the substrate 10, the scraper assembly 20 can be prevented from being lost.

[0032] Furthermore, grooves 18 are provided at both ends of the scraper storage position 17 to facilitate the placement and removal of the scraper assembly 20.

[0033] Furthermore, a label attachment position 19 for attaching the LCM module label is also provided on the top of the substrate 10. The label attachment position 19 is located on the side of the placement position 11 away from the scraper storage position 17.

[0034] In summary, the LCM lamination fixture in the above embodiments of this utility model allows the operator to connect the air pump to the air duct interface and start the air pump, adjusting it to jet mode. This allows the air ejected through the corrugated pipe and positioning holes to remove dust from the placement area, preventing dust and impurities from entering between the film and the screen during subsequent LCM lamination. After dust removal from the placement area, the air pump is turned off, and the LCM module is placed on the placement area and fixed using multiple positioning components around the LCM module. This improves the placement accuracy of the LCM module and enhances its stability during lamination. After fixing the LCM module, the corresponding nozzle structure is selected according to the required lamination and installed on the corrugated pipe. The air pump is then started and adjusted to suction mode. The nozzle structure adsorbs the side of the lamination furthest from the release paper and... The film is moved to the top of the LCM module. At this point, the release paper is peeled off, and the film is attached to the LCM module. Simultaneously, the positioning holes will vacuum the area around the LCM module to prevent fingerprints from getting on the surface of the LCM module and the protective film due to manual application. After the LCM film is attached to the LCM module, the air pump is turned off, and the LCM film is smoothed using the squeegee structure. By wrapping an isolation layer on the outside of the squeegee structure, the isolation layer can cover the edge of the squeegee structure to prevent scratches on the LCM film during the smoothing process. By wrapping buffer layers at both ends of the isolation layer in the width direction, the friction between the squeegee structure and the protective film during the smoothing process can be reduced to prevent dirt and scratches. During the LCM film application process, the squeegee structure can be attached to the substrate by the adsorption structure to prevent accidental damage.
