[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0027] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0028] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0029] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a glue applying device 100 . The glue applying device 100 includes a positioning member 10 and a negative pressure mechanism 20 .

[0030] Combine Figure 3 As shown, the positioning member 10 is provided with a first positioning groove 11, a second positioning groove 12, and a vacuum chamber 13. The second positioning groove 12 and the vacuum chamber 13 are respectively located on opposite sides of the first positioning groove 11 and are connected to the first positioning groove 11. The first positioning groove 11 is used to install the adhesive assembly 200, and the second positioning groove 12 is used to install the speaker 300. The negative pressure mechanism 20 is connected to the vacuum chamber 13 and is used to generate a negative pressure in the vacuum chamber 13 to provide an adsorption force that causes the adhesive assembly 200 to adhere to the bottom surface of the first positioning groove 11.

[0031] By setting a first positioning groove 11 on the positioning member 10, the first positioning groove 11 has a bottom surface connected to the vacuum chamber 13 on the side away from the second positioning groove 12, and the back glue component 200 can be installed in the first positioning groove 11 to realize the positioning of the back glue component 200. Thereafter, the negative pressure mechanism 20 can form a negative pressure in the vacuum chamber 13, so that the back glue component 200 is tightly fitted to the bottom surface of the first positioning groove 11 under the action of the negative pressure, ensuring that the surface to be fitted of the back glue component 200 matches the surface to be fitted of the speaker 300. For example, if the surface to be fitted of the speaker 300 is a plane, then when the back glue component 200 is tightly fitted to the bottom surface of the first positioning groove 11 under the action of negative pressure, the surface to be fitted of the back glue component 200 is a plane. Then, the speaker 300 is installed in the second positioning groove 12 to achieve the positioning between the speaker 300 and the adhesive component 200, and the surface to be bonded of the speaker 300 and the surface to be bonded of the adhesive component 200 are bonded to achieve the assembly of the speaker 300 and the adhesive component 200. During the assembly process, the first positioning groove 11 and the second positioning groove 12 can limit the relative position of the adhesive component 200 and the speaker 300, improve the positioning accuracy between the adhesive component 200 and the speaker 300, and ensure the accuracy of the bonding position of the two. The negative pressure mechanism 20 can ensure that the surface to be bonded of the adhesive component 200 matches the surface to be bonded of the speaker 300, so that the surface to be bonded of the adhesive component 200 and the surface to be bonded of the speaker 300 can be tightly bonded and adhered everywhere, thereby improving the fit between the adhesive component 200 and the speaker 300 and improving the sealing of the speaker 300.

[0032] For example, combined Figure 2 and Figure 3As shown, the first positioning groove 11 has a bottom surface connected to the vacuum cavity 13, and a side wall surface connected to the second positioning groove 12. The bottom surface has an opening connected to the vacuum cavity 13. The adhesive backing component 200 has a first side and a second side arranged opposite to each other. When the adhesive backing component 200 is installed in the first positioning groove 11, the first side of the adhesive backing component 200 is attached to the bottom surface of the first positioning groove 11 and covers the opening on the bottom surface. When negative pressure is formed in the vacuum cavity 13, an adsorption force is generated on the first side of the adhesive backing component 200, so that the first side of the adhesive backing component 200 is more closely attached to the bottom surface, preventing a large gap between the adhesive backing component 200 and the bottom surface, so that different positions of the first side of the adhesive backing component 200 are supported by the bottom surface, and the surface to be attached on the second side of the adhesive backing component 200 matches the surface to be attached on the speaker 300.

[0033] Exemplarily, the shape and size of the first positioning groove 11 match the shape and size of the adhesive backing component 200, so that when the adhesive backing component 200 is installed in the first positioning groove 11, the outer peripheral edge of the adhesive backing component 200 at least partially fits the side wall surface of the first positioning groove 11 to limit the position of the adhesive backing component 200 on the positioning member 10.

[0034] like Figure 3 As shown, in some embodiments, the adhesive assembly 200 includes a release film 210 and an adhesive 220 that is releasably connected to the release film 210. The release film 210 is located on a first side of the adhesive assembly 200, and the release film 210 can be attached to the bottom surface of the first positioning groove 11. The release film 210 and / or the adhesive 220 abut against the side wall surface of the first positioning groove 11. The adhesive 220 is located on a second side of the adhesive assembly 200, and the side of the adhesive 220 facing away from the release film 210 has a surface to be attached. The surface to be attached of the adhesive 220 is attached to the surface to be attached of the speaker 300.

[0035] Furthermore, the release film 210 includes a main body region 211 and a hand-tear region 212. Adhesive backing 220 is disposed on the main body region 211. The first positioning groove 11 has a first groove body and a second groove body that are connected. The main body region 211 and adhesive backing 220 of the release film 210 can be installed in the first groove body, and the hand-tear region 212 is installed in the second groove body. The vacuum chamber 13 is connected to the first groove body. When the vacuum chamber 13 forms a negative pressure, it can provide an adsorption force to the main body region 211 of the release film 210, so that at least the main body region 211 of the release film 210 is tightly attached to the bottom surface of the first groove body.

[0036] For example, the groove depth of part of the first positioning groove 11 along the Z direction may be smaller than the thickness of the adhesive backing assembly 200, so that part of the adhesive backing assembly 200 is located in the first positioning groove 11, and the other part protrudes from the first positioning groove 11 and is located in the second positioning groove 12, so that the speaker 300 can fit tightly with the adhesive backing assembly 200 when installed in the second positioning groove 12.

[0037] In some embodiments, the negative pressure mechanism 20 includes a vacuum generator or a vacuum pump that can extract air from the vacuum pump to create a negative pressure in the vacuum chamber 13 , thereby providing an adsorption force that allows the adhesive assembly 200 to adhere to the bottom surface of the first positioning groove 11 .

[0038] In an optional embodiment, the adhesive laminating device 100 further includes a gas compression mechanism (not shown), which is connected to the vacuum generator and is used to generate compressed gas. It is understood that the gas compression mechanism is capable of generating compressed gas, and the gas compression mechanism is connected to the vacuum generator, so that the compressed gas generated by the gas compression mechanism can be connected to the vacuum generator. The compressed gas is a gas that has been compressed from atmospheric air to increase its pressure and density.

[0039] In another optional embodiment, the adhesive laminating device 100 further includes a compressed gas tank (not shown), which is connected to the vacuum generator and is used to provide compressed gas to the vacuum generator. It is understood that the compressed gas tank stores compressed gas and is connected to the vacuum generator, so that the compressed gas in the compressed gas tank can be connected to the vacuum generator. The compressed gas is a gas that has been compressed from atmospheric air to increase its pressure and density.

[0040] By connecting compressed gas to the vacuum generator through a gas compression mechanism or a compressed gas tank, the suction capacity of the vacuum generator can be improved, so that the vacuum chamber 13 forms a negative pressure more quickly and a higher vacuum degree is achieved in the vacuum chamber 13, thereby providing a greater adsorption force to the back glue component 200 more quickly, improving the fit between the back glue component 200 and the first positioning groove 11, thereby improving the fit between the back glue component 200 and the speaker 300, and at the same time improving the assembly efficiency of the back glue component 200 and the speaker 300.

[0041] like Figure 2 As shown, in some embodiments, the adhesive application device 100 further includes a base 30, the negative pressure mechanism 20 is connected to the base 30, and the positioning member 10 is detachably connected to the base 30. The base 30 is provided with a through hole 30a, which connects the vacuum chamber 13 of the positioning member 10 and the negative pressure mechanism 20. It will be understood that the positioning member 10 is detachably connected to the base 30, and the vacuum chamber 13 of the positioning member 10 is connected to the negative pressure mechanism 20 through the through hole 30a, which facilitates the replacement of the positioning member 10.

[0042] For example, when it is necessary to attach the adhesive backing assembly 200 to different types of speakers 300, the type of positioning member 10 provided on the base 30 can be changed so that the first positioning groove 11 and the second positioning groove 12 of the positioning member 10 are respectively adapted to the adhesive backing assembly 200 and the speaker 300 to be attached. The positioning member 10 can be connected to the base 30 by screws or clamping, which makes the connection method more flexible and varied.

[0043] For example, Figure 2 As shown, the base 30 may be provided with one or more through holes 30 a.

[0044] Preferably, the base 30 is provided with two or more through holes 30a, so that the negative pressure mechanism can be connected to the vacuum chamber 13 through multiple through holes 30a, thereby being able to achieve a higher vacuum degree in the vacuum chamber 13, and provide a greater adsorption force to the back glue component 200 more quickly, thereby improving the fit between the back glue component 200 and the first positioning groove 11, thereby improving the fit between the back glue component 200 and the speaker 300, and at the same time, it can also improve the assembly efficiency of the back glue component 200 and the speaker 300.

[0045] For example, Figure 2 As shown, the positioning member 10 is arranged on the outside of the base 30, and the base 30 is provided with an inner cavity and multiple through holes 30a. The negative pressure mechanism is arranged in the inner cavity of the base 30 and is connected to the through holes 30a of the base 30 through a connecting pipe to connect to the vacuum cavity 13 of the positioning member 10.

[0046] Furthermore, the adhesive laminating device 100 further includes a sealing member 40, through which the positioning member 10 is sealedly connected to the base 30. Providing the sealing member 40 between the positioning member 10 and the base 30 results in a sealed connection between the positioning member 10 and the sealing member 40, which helps ensure that a sealed cavity is formed between the vacuum chamber 13 and the through hole 30a, thereby ensuring that a stable negative pressure is formed within the vacuum chamber 13, and ensuring that the adhesive assembly 200 can stably adhere to the bottom surface of the first positioning groove 11 under the action of the negative pressure.

[0047] Illustratively, the sealing member 40 includes a sealing ring.

[0048] Specifically, the base 30 or the positioning member 10 is provided with a sealing groove, which is located at the periphery of the vacuum cavity 13 and the through holes 30a. The sealing member 40 is provided in the sealing groove, so that a sealed cavity is formed between the vacuum cavity 13 and the plurality of through holes 30a.

[0049] For example, Figure 3 As shown, the sealing member 40 is an annular sealing groove, and the base 30 is provided with an annular sealing groove.

[0050] In some embodiments, the negative pressure mechanism 20 is connected to one end of a connecting tube (not shown), and the other end of the connecting tube is provided with a joint 21, which is threadedly connected to the through hole 30a of the base 30. It can be understood that the threaded connection between the joint 21 and the through hole 30a of the base 30 can ensure the stability of the connection between the two. The joint 21 is a hollow joint 21, and the hollow portion of the joint 21 can achieve communication between the through hole 30a of the base 30 and the channel of the connecting tube, so that the negative pressure mechanism 20 is connected to the through hole 30a of the base 30.

[0051] In some embodiments, such as Figure 1 As shown, the base 30 is also provided with a pipe joint 31, one side of the pipe joint 31 can be connected to the pipe inside the base 30 that is connected to the vacuum generator, and the other side can be connected to the pipe outside the base 30 that is connected to the gas compression mechanism or compressed gas tank, so that the gas compression mechanism / compressed gas tank is connected to the vacuum generator.

[0052] In some embodiments, such as Figure 1 As shown, the base 30 is provided with a switch 32, which is electrically connected to the negative pressure mechanism 20. Exemplarily, the switch 32 may be located on the side of the base 30 where the positioning member 10 is located. By switching the state of the switch 32, the start and stop of the negative pressure mechanism 20 are controlled, so that when the adhesive component 200 and the speaker 300 are attached, the negative pressure mechanism 20 is turned on, negative pressure is formed in the vacuum chamber 13, and adsorption force is provided for the adhesive component 200. When the adhesive component 200 and the speaker 300 are attached, the negative pressure mechanism 20 is turned off, the adsorption force is reduced or removed, so that the adhesive component 200 and the speaker 300 can be removed from the positioning member 10 in a stable attached state.

[0053] In other embodiments, the negative pressure mechanism 20 may also be communicatively connected to the controller, and the controller may control the negative pressure mechanism 20 to be periodically opened to realize the start and stop of the negative pressure mechanism 20 .

[0054] Combine Figure 2 and Figure 4 As shown, in some embodiments, the vacuum chamber 13 includes a first cavity 131 and multiple second cavities 132. The first cavity 131 communicates with the negative pressure mechanism 20 and the multiple second cavities 132. The multiple second cavities 132 are spaced apart and respectively communicate with the first positioning groove 11. The multiple second cavities 132 communicate with the first positioning groove 11, providing adsorption force to different positions of the adhesive component 200, which helps to make the distribution of adsorption force more uniform, so that the adhesive component 200 can be more stably attached to the bottom surface of the first positioning groove 11.

[0055] Illustratively, the adhesive 220 in the adhesive assembly 200 is a ring-shaped structure.

[0056] Furthermore, the side of the release film 210 facing away from the adhesive 220 is in contact with the bottom surface of the first positioning groove. The plurality of second cavities 132 are distributed in an annular pattern and are provided corresponding to the adhesive 220. Thus, when a negative pressure is formed within the vacuum chamber 13, an adsorption force is provided to the portion of the release film 210 corresponding to the adhesive 220. It will be appreciated that the portion of the release film 210 corresponding to the adhesive 220 has relatively high strength, providing an adsorption force to the portion of the release film 210 corresponding to the adhesive 220. This prevents deformation of the adhesive assembly 200 under the action of the adsorption force, thereby ensuring that the entire release film 210 is tightly adhered to the bottom surface of the first positioning groove 11.

[0057] Furthermore, the first cavity 131 corresponds to the first positioning groove 11, and the vacuum cavity 13 also includes multiple third cavities 133, which extend in a direction perpendicular to the first positioning groove 11 to the second positioning groove 12, so that the first cavity 131 can be connected to different through holes 30a on the base 30 through different third cavities 133, which is beneficial to control the volume of the first cavity 131, so that the negative pressure mechanism 20 can form negative pressure in the vacuum cavity 13 more quickly, thereby improving the fitting efficiency of the speaker 300 and the back glue assembly 200.

[0058] like Figure 3 As shown, in some embodiments, the positioning member 10 is further provided with a first avoidance groove 14, which is connected to the first positioning groove 11. The first avoidance groove 14 is used to form an operating position that is convenient for taking and placing the adhesive-backed component 200. By providing the first avoidance groove 14 and making it connected to the first positioning groove 11, a human hand or a robot can reach into the first avoidance groove 14, making it convenient for the human hand or the robot to grasp the adhesive-backed component 200 located in the first positioning groove 11 and remove the adhesive-backed component 200 from the first positioning groove 11.

[0059] Exemplarily, the first avoidance groove 14 can be connected to the second groove body of the first positioning groove 11, so that a human hand or a robotic arm can reach into the first avoidance groove 14 and clamp the hand-tear area 212 of the release film 210 located in the second groove body to remove the adhesive component 200 from the first positioning groove 11.

[0060] like Figure 3 As shown, in some embodiments, the positioning member 10 is further provided with a second avoidance groove 15, which is connected to the second positioning groove 12. The second avoidance groove 15 is used to form an operating position for conveniently removing and placing the speaker 300. By providing the second avoidance groove 15 and connecting it to the second positioning groove 12, a human hand or a robot can reach into the second avoidance groove 15, conveniently grasping the speaker 300 located in the second positioning groove 12 and removing the speaker 300 from the second positioning groove 12. Alternatively, a human hand or a robot can grasp the speaker 300, reach into the second avoidance groove 15, and stably install the speaker 300 in the second positioning groove 12.

[0061] The following describes the process of applying the adhesive backing 220 using the adhesive laminating device 100 according to the embodiment of the present application.

[0062] First, the compressed gas generated by the gas compression mechanism or the compressed gas stored in the compressed gas tank can be connected to the negative pressure mechanism 20, and then the adhesive component 200 is installed in the first positioning groove 11, and the control switch 32 is used to turn on the vacuum generator, so that the vacuum generator runs and forms a negative pressure in the vacuum chamber 13, so that the adhesive component 200 is tightly fitted to the bottom surface of the first positioning groove 11, and finally the speaker 300 is installed in the second positioning groove 12, and the surface to be fitted of the speaker 300 is tightly fitted and glued to the surface to be fitted of the adhesive component 200, thereby realizing the assembly of the speaker 300 and the adhesive component 200.
