Description

Technical Field

[0001] This application relates to the field of fixture technology, specifically to glue injection fixtures and vacuum glue injection equipment. Background Technology

[0002] Some products consist of a metal sheet and a resin part embedded in a groove within the metal sheet. Typically, the metal sheet and resin part can be molded separately, and then the resin part can be glued into the groove; however, this method is complex and costly. To simplify the process and reduce costs, molten resin material can be directly injected into the groove, and after curing, the resin part is obtained.

[0003] However, existing injection fixtures have difficulty removing air bubbles generated during the injection molding process and addressing the issue of resin material failing to fill the grooves. Utility Model Content

[0004] To address the shortcomings of the existing technology, it is necessary to provide a dispensing fixture. Furthermore, it is necessary to provide a vacuum dispensing apparatus incorporating this dispensing fixture.

[0005] This application provides a glue-dispensing fixture for vacuum glue dispensing onto a component. The component includes a first surface and a second surface. A glue-dispensing groove is provided on the component, extending from the first surface through the second surface. The glue-dispensing fixture includes an upper template and a lower template. The upper template is configured to be fixed to the first surface. A first sealing member is provided on the upper template facing the first surface, sealing the glue-dispensing groove on one side of the first surface. The lower template is configured to be fixed to the second surface. A second sealing member is provided on the lower template facing the second surface, sealing the glue-dispensing groove on one side of the second surface. The first and second sealing members are configured to close the glue-dispensing groove and form a closed cavity with it.

[0006] The upper and lower molds, along with the first and second sealing elements, form a closed cavity, enabling vacuum injection. In a vacuum environment, the resin more easily fills all voids, reducing air bubble formation because gas is effectively expelled, preventing bubble formation. The closed cavity structure allows for uniform resin distribution during injection, preventing incomplete filling caused by resin shrinkage or uneven flow during curing. The sealing design ensures resin fully fills every corner of the injection tank, improving the filling degree and consistency of the injection-molded parts. The vacuum environment and closed structure effectively eliminate air bubbles generated during injection, ensuring product defect-free performance. This ensures uniform resin distribution and full filling of the injection tank, preventing incomplete filling and improving production stability and product consistency.

[0007] In some embodiments of this application, an adhesive injection portion is provided on the side of the upper template facing away from the first surface. The first seal has a connecting portion that protrudes through and connects to the adhesive injection portion on the side facing the adhesive injection portion, and the connecting portion has an adhesive injection port that communicates with the adhesive injection groove.

[0008] In some embodiments of this application, a first groove is provided on the side of the upper template facing the glue injection groove. At least a portion of the first seal is fixed in the first groove, and a second groove is provided on the side of the lower template facing the glue injection groove, with at least a portion of the second seal fixed in the second groove.

[0009] In some embodiments of this application, a mounting groove is provided on the side of the lower template near the injection part, and the mounting groove is configured to fix at least part of the injection part.

[0010] In some embodiments of this application, the lower template is provided with a locking mechanism, and the upper template is provided with a snap-fit ​​groove on the side opposite to the lower template. The locking mechanism is rotatably connected to the lower template and configured to snap-fit ​​with the snap-fit ​​groove to fix the upper template to the lower template.

[0011] In some embodiments of this application, an operating part is also provided on the side of the upper template opposite to the glue injection part.

[0012] In some embodiments of this application, both the first seal and the second seal are provided with flow channels.

[0013] This application also provides a vacuum dispensing apparatus, including a frame, a worktable mounted on the frame, and a dispensing head mounted on the frame. The vacuum dispensing apparatus further includes the aforementioned dispensing fixture, which is mounted on the worktable. The dispensing head is configured to dispense adhesive into the dispensing fixture.

[0014] In some embodiments of this application, a first moving mechanism and a second moving mechanism are provided on the worktable. A dispensing head is disposed on the first moving mechanism and configured to move along a first direction, while a dispensing fixture is disposed on the second moving mechanism and configured to move along a second direction.

[0027] 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.

[0028] Please see Figures 1 to 3This application provides a glue injection fixture 10 for vacuum glue injection of a glue injection component 100. The glue injection component 100 includes a first surface 110 and a second surface 120. The glue injection component 100 is provided with a glue injection groove 101, which extends from the first surface 110 through the second surface 120. The glue injection fixture 10 includes an upper template 200 and a lower template 300. The upper template 200 is configured to be fixed to the first surface 110. A first sealing member 400 is provided on the upper template 200 facing the first surface 110, and the first sealing member 400 is used to seal the glue injection groove 101 located on one side of the first surface 110. The lower template 300 is configured to be fixed to the second surface 120. A second sealing member 500 is provided on the lower template 300 facing the second surface 120. The second sealing member 500 is used to seal the glue injection groove 101 located on the second surface 120. The first seal 400 and the second seal 500 are configured to close the glue injection groove 101 and form a closed cavity with the glue injection groove 101.

[0029] The upper and lower mold plates 300, along with the first and second sealing elements 400 and 500, cooperate to form a closed cavity, achieving vacuum injection molding. In a vacuum environment, the resin more easily fills all voids, reducing bubble formation because gas is effectively expelled under vacuum. The closed cavity structure allows for uniform resin distribution during injection, preventing incomplete filling caused by resin shrinkage or uneven flow during curing. The sealing design ensures that the resin fully fills every corner of the injection molded part 101, improving the filling degree and consistency. The vacuum environment and closed structure effectively expel air bubbles generated during injection molding, ensuring product defect-free performance. This ensures uniform resin distribution and full filling of the injection molded part 101, preventing incomplete filling and improving production stability and product consistency.

[0030] Please see Figures 1 to 3In one embodiment of this application, an injection section 210 is provided on the side of the upper template 200 opposite to the first surface 110. A connecting portion 401 protrudes from the side of the first sealing member 400 facing the injection section 210, passing through and connecting to the injection section 210. The connecting portion 401 has an injection port 402 communicating with the injection groove 101. By providing the injection section 210 on the side of the upper template 200 opposite to the first surface 110 and connecting it to the injection section 210 via the connecting portion 401, a highly efficient injection channel is formed. The design of the connecting portion 401 makes the injection operation more convenient, and the opening of the injection port 402 further optimizes the accuracy and efficiency of the injection. During the injection process, the connecting portion 401 can effectively guide the resin flow to the injection groove 101, avoiding the problem of resin displacement or uneven distribution during the injection process. Meanwhile, the cooperation between the dispensing section 210 and the connecting section 401 also prevents contamination during the dispensing process, ensuring a clean dispensing environment, thereby improving the quality and reliability of the final product. This design significantly improves the stability and consistency of the dispensing operation, reduces the scrap rate caused by uneven dispensing, and increases production efficiency and product consistency. Preferably, four dispensing sections 210 can be provided, located around the upper template 200.

[0031] Please see Figure 2 and Figure 3 In one embodiment of this application, a first groove 201 is provided on the side of the upper template 200 facing the glue injection groove 101. At least a portion of the first sealing member 400 is fixed within the first groove 201, and a second groove 301 is provided on the side of the lower template 300 facing the glue injection groove 101, with at least a portion of the second sealing member 500 fixed within the second groove 301. By providing the first groove 201 and the second groove 301 on the upper template 200 and the lower template 300 respectively, and connecting them with the first sealing member 400 and the second sealing member 500, the sealing performance of the first groove 201 and the second groove 301 is further enhanced. The design of the first groove 201 and the second groove 301 allows the sealing member to fit more tightly with the template, reducing the risk of leakage from the closed cavity. Meanwhile, the presence of the first groove 201 and the second groove 301 can also guide the position of the first seal 400 and the second seal 500, ensuring that the first seal 400 and the second seal 500 are precisely matched with the upper template 200 and the lower template 300, thus avoiding poor sealing problems caused by installation errors.

[0032] Please see Figure 2In one embodiment of this application, a mounting groove 310 is provided on the side of the lower template 300 near the injection part 100. The mounting groove 310 is configured to fix at least a portion of the injection part 100. By providing a mounting groove 310 on the side of the lower template 300 near the injection part 100 and embedding the injection part 100 therein, this technical means significantly improves the fixation and stability of the injection part 100. It avoids the problem of incomplete molding caused by the movement or displacement of the injection part 100. At the same time, the design of the mounting groove 310 can also ensure the precise fit between the injection part 100 and the template, reducing the problem of uneven injection caused by installation errors. In addition, the presence of the mounting groove 310 can also reduce the possibility of the injection part 100 shifting due to external forces during the injection process, thereby improving the stability and consistency of the injection process.

[0033] Please see Figures 2 to 3 In one embodiment of this application, the lower template 300 is provided with a locking mechanism 600, and the upper template 200 has a snap-fit ​​groove 202 on the side opposite to the lower template 300. The locking mechanism 600 is rotatably connected to the lower template 300 and configured to snap into the snap-fit ​​groove 202 to fix the upper template 200 to the lower template 300. By providing the locking mechanism 600 on the lower template 300 and the snap-fit ​​groove 202 on the side of the upper template 200 opposite to the lower template 300, quick connection and fixation of the upper template 200 and the lower template 300 are achieved. The flip-up design of the locking mechanism 600 allows the upper template 200 to easily snap into the lower template 300. At the same time, the design of the snap-fit ​​groove 202 also ensures precise fit between the upper template 200 and the lower template 300, avoiding loosening of the snap-fit ​​groove 202 due to installation errors. In addition, the design of the locking mechanism 600 can reduce the occurrence of poor mold connection due to improper manual operation, thereby improving the service life and stability of the mold. Preferably, the locking mechanism 600 can be a cam locking mechanism 600.

[0034] Please see Figure 1 In one embodiment of this application, an operating part 700 is also provided on the side of the upper template 200 opposite to the glue injection part 100. By providing the operating part 700 on the side of the upper template 200 opposite to the glue injection part 100, the ease of operation for separating the glue injection part 100 is significantly improved.

[0035] Please see Figure 3 and Figure 4In one embodiment of this application, both the first sealing member 400 and the second sealing member 500 are provided with flow channels 800. By providing flow channels 800 in the first sealing member 400 and the second sealing member 500, this technique optimizes the flow path of the resin during the injection process. The design of the flow channels 800 can guide the resin to flow more evenly and quickly to all corners of the closed cavity, reducing resistance and pressure during resin flow, thereby improving the efficiency and consistency of injection. In addition, the design of the flow channels 800 can also ensure that the resin can fully fill all areas of the closed cavity, avoiding the problem of incomplete filling caused by uneven flow. Preferably, the minimum height of the flow channels 800 of the first sealing member 400 and the second sealing member 500 is 2mm, which can improve the problems of shrinkage and excessive air bubbles after injection.

[0036] Please see Figure 5 and Figure 6 This application also provides a vacuum dispensing apparatus 20, including a frame 900, a worktable 910 mounted on the frame 900, and a dispensing head 920 mounted on the frame 900. The vacuum dispensing apparatus 20 further includes the aforementioned dispensing fixture 10, which is mounted on the worktable 910. The dispensing head 920 is configured to dispense adhesive into the dispensing fixture 10. A vacuum hood 913 is also mounted on the worktable 910, and a vacuum pump 914 is connected to one side of the vacuum hood 913. The vacuum pump 914 can maintain a vacuum state inside the vacuum hood 913, improving the problem of excessive air bubbles after dispensing adhesive into the part 100.

[0037] Please see Figure 6In one embodiment of this application, a first moving mechanism 911 and a second moving mechanism 912 are provided on the worktable 910. A dispensing head 920 is disposed on the first moving mechanism 911 and configured to move along a first direction X, while a dispensing fixture 10 is disposed on the second moving mechanism 912 and configured to move along a second direction Y. The first direction X intersects the second direction Y. By providing the first moving mechanism 911 and the second moving mechanism 912 on the worktable 910, and respectively mounting the dispensing head 920 and the dispensing fixture 10 onto these moving mechanisms, this technical means achieves independent movement functions for the dispensing head 920 and the dispensing fixture 10. The dispensing head 920 can move along the first direction X, enabling precise alignment of the dispensing position and reducing dispensing deviation caused by operational errors. Simultaneously, the dispensing fixture 10 can move along the second direction Y, enabling rapid positioning to the required dispensing position, further improving operational efficiency. This allows the dispensing head 920 and dispensing fixture 10 to be precisely adjusted according to actual needs, ensuring flexibility and consistency in the dispensing process. Furthermore, the first moving mechanism 911 and the second moving mechanism 912 reduce uneven dispensing caused by improper manual operation, thereby improving product quality and production efficiency. The vacuum dispensing equipment 20 significantly improves operational flexibility and positioning accuracy, reducing scrap rates due to movement errors and enhancing product quality and production efficiency.

[0038] Please see Figure 6 In one embodiment of this application, the first moving mechanism 911 is further provided with a heating device 930, and the dispensing fixture 10 is disposed on the heating device 930. By providing the heating device 930 on the first moving mechanism 911 and dispensing the dispensing fixture 10 on the heating device 930, this technical means significantly optimizes the resin flow characteristics during the dispensing process. The heating device 930 can preheat the resin, reducing its viscosity and enhancing its fluidity, thereby ensuring that the resin can be filled into all areas of the closed cavity more evenly and quickly. At the same time, the presence of the heating device 930 can also reduce the problem of uneven resin flow caused by uneven temperature during the dispensing process, further improving the efficiency and consistency of dispensing. In addition, the heating device 930 can also accelerate the resin curing speed, shorten the production cycle, and thus improve production efficiency. Through this design, the resin's flow properties and curing characteristics are significantly optimized, reducing the scrap rate caused by uneven flow and improving product quality and production efficiency.
