[0003] Currently, for the glue injection operation of heterogeneous cover plates, most are manual glue injection and jig-assisted glue injection. However, although manual glue injection can flexibly adapt to complex shapes to ensure uniform distribution of glue, the glue injection efficiency is low, and it is difficult to control the glue injection angle and ensure the consistency of the glue injection amount for products in the same batch, affecting the overall quality of the products. Although jig-assisted glue injection can improve production efficiency and assist in controlling the glue injection angle to ensure the consistency of the glue injection amount for products in the same batch, it cannot adjust the working angle of the product at any time according to requirements, cannot ensure uniform distribution of glue, and the glue injection effect is limited.

[0035] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0037] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of this application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] In this application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "joined", "fixed", etc., these terms should be understood in a broad sense.

If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0041] In the automotive screen bonding industry, the glue injection process is a process that has to be considered during the processing of special-shaped covers. Since special-shaped covers usually have complex curved surfaces or irregular shapes, these complex shapes make it difficult for mechanical automation to precisely control the glue injection angle and position. Therefore, in the prior art, glue injection mostly relies on manual adjustment of the glue injection angle to fill the entire screen with glue.

[0042] However, although manual glue injection can flexibly adapt to complex shapes and ensure uniform distribution of the glue, manual adjustment of the angle for glue injection is difficult, with low efficiency, and the operation angles vary greatly for each operation and when different personnel perform the operation. Problems such as glue injection bubbles (poor exhaust of the glue injection angle), backflow bubbles (glue flows out at the glue injection port and exhaust port, with less glue bubbles), angle problems due to product sliding, IML cover plate bump damage, and poor glue injection caused by bending of the glue injection tube and needle tip are likely to occur. It is difficult to control the glue injection angle and ensure the consistency of the glue injection amount for products in the same batch, which affects the overall quality of the products.

[0043] Therefore, currently, a jig-assisted glue injection method is provided to address the problems of manual glue injection. Although jig-assisted glue injection can improve production efficiency and assist in controlling the glue injection angle to ensure the consistency of the glue injection amount for products in the same batch, it cannot adjust the operation angle of the product at any time according to requirements, resulting in possible aggregation and blockage of the glue when it flows in the product, and unable to ensure uniform distribution of the glue, with limited impact on the glue injection effect.

[0044] In summary, this application provides a glue injection jig that can adjust the angle in real time according to requirements to solve the above problems.

[0045] Referring to Figure 1 , an embodiment of this application provides a glue injection jig for glue injection of special-shaped covers. The glue injection jig includes a base 1, a first support assembly 2, and a second support assembly 3. The first support assembly 2 and the second support assembly 3 are arranged at intervals in the horizontal direction on the base 1. The first support assembly 2 is used to fix and adjust the angle of the special-shaped cover, and the second support assembly 3 is used to fix the glue injector so that the glue injector can automatically complete the glue injection operation on the special-shaped cover.

[0046] Specifically, when setting, referring to Figure 1 and Figure 2, the base 1 has a supporting surface 11. The first supporting component 2 includes a first support member 21 and a first fixing base 22. The first support member 21 is disposed on the supporting surface 11 of the base 1, and the first fixing base 22 is disposed on the first support member 21 with adjustable angle and is configured to fix the special-shaped cover plate. After the special-shaped cover plate is fixed on the first fixing base 22, it can be rotated under the drive of the first fixing base 22 to adjust its working angle, so as to avoid the problem of poor exhaust caused by the injection angle during the injection process, avoid the formation of injection bubbles, and also solve the problems such as less glue volume and glue flowing out of the injection port and exhaust port of the product.

[0047] In addition, in the assembly line operation of the same product, after the preset inclination angle of the first fixing base 22 is adjusted in advance, it can be ensured that each product of the same model can be placed at the same preset inclination angle when placed in the injection jig, ensuring the consistency of the injection volume of the products in the same batch.

[0048] The second supporting component 3 includes a second support member 31 and a second fixing base 32. The second support member 31 is disposed on the supporting surface 11 of the base 1 and is spaced from the first supporting component 2 in the horizontal direction. The second fixing base 32 is disposed on the second support member 31 with adjustable height and is configured to fix the injector. After the injector is fixed on the second fixing base 32, it can be lifted and lowered under the drive of the second fixing base 32 to adjust its working height, so that the glue inside it can be automatically injected into the special-shaped cover plate under the action of gravity.

[0049] It can be understood that in the embodiment of the present application, the injector is an injection tube filled with glue inside, and an injection needle is provided at the glue outlet of the injection tube. By tilting the injection tube and inserting the injection needle into the injection port of the special-shaped cover plate, the injector can realize the automatic injection operation of the special-shaped cover plate under the action of gravity.

[0050] In addition, since the pipeline in the special-shaped cover plate has a complex shape, even if the initial working angle is adjusted, there will still be a situation where the glue cannot flow to the pipeline located at a higher position because it is at a lower position during the injection operation. At this time, the angle of the first fixing base 22 can be adjusted in real time to change the working angle of the special-shaped cover plate, so that the pipeline previously located at a higher position moves to a lower position, and the glue can continue to be injected under the action of gravity.

[0051] In summary, when the glue injection fixture of the present application is in use, the special-shaped cover plate can be first placed on the first fixing seat 22, and the angle of the first fixing seat 22 is adjusted until the first fixing seat 22 and the base 1 reach the set angle, so that the special-shaped cover plate reaches the set working angle. Then, the glue injector is placed on the second fixing seat 32, and the height of the second fixing seat 32 is adjusted to ensure that the glue injector will not be bent, guaranteeing the smoothness of subsequent glue injection. After that, the glue injection needle of the glue injector is inserted into the glue injection port of the special-shaped cover plate, enabling the glue injector to automatically inject glue into the special-shaped cover plate under the action of gravity. During the glue injection process, the operator can view the position of the glue in real time and adjust the angle of the first fixing seat 22 according to the flow direction of the glue in the special-shaped cover plate to ensure uniform distribution of the glue.

[0052] By adjustably arranging the first fixing seat 22 on the first support member 21 and fixing the special-shaped cover plate with the first fixing seat 22, the above-mentioned glue injection fixture can adjust the angle of the first fixing seat 22 to the specified angle before glue injection during specific operations, thereby controlling the glue injection angle of the special-shaped cover plate and ensuring the consistency of the glue injection amount of products in the same batch. Moreover, during the glue injection process, the angle of the first fixing seat 22 can be adjusted at any time according to requirements, thereby adjusting the working angle of the special-shaped cover plate, ensuring uniform distribution of the glue, and guaranteeing the glue injection effect and the overall quality of the product.

[0053] Refer to Figure 1 and Figure 2 In one embodiment, the first support assembly 2 further includes a spherical universal joint 23. The spherical universal joint 23 is arranged on the first support member 21 and connected to the first fixing seat 22. The first fixing seat 22 can flexibly adjust its angle through the spherical universal joint 23.

[0054] Specifically, the spherical universal joint 23 includes a first joint head and a second joint head that are rotatably connected to each other. The first support assembly 2 is connected to the first joint head, and the first fixing seat 22 is connected to the second joint head. By using the connection of the spherical universal joint 23 to the first support assembly 2 and the first fixing seat 22, the first fixing seat 22 can flexibly adjust its angle driven by the spherical universal joint 23.

[0055] In one embodiment, the first support member 21 is a height adjustment frame, so that the first support member 21 can not only support the first fixing seat 22 but also adjust the height of the first fixing seat 22, enabling the height of the special-shaped cover plate to be adjusted according to requirements.

[0056] Specifically, the first support member 21 may include a first frame body and a second frame body. Along the height direction, the first frame body is telescopically assembled on the second frame body to achieve the effect of adjusting the length of the first support member 21. The first fixing seat 22 is arranged on the first frame body to adjust its own height when the first frame body expands and contracts relative to the second frame body.

[0057] See also Figures 1-3 In one embodiment, the first fixing seat 22 includes a fixing plate 221 and a positioning member 222. The positioning member 222 is disposed on the fixing plate 221 and is configured to limit the position of the special-shaped cover plate on the fixing plate 221 to ensure the stability of the special-shaped cover plate on the first fixing seat 22.

[0058] Specifically, the positioning member 222 is a positioning retaining ring, which is arranged on the fixing plate 221 and cooperates with the fixing plate 221 to form a positioning groove 24. The positioning groove 24 is located on the side of the first fixing seat 22 away from the base 1 and can accommodate a special-shaped cover plate.

[0059] See also Figure 1 and Figure 2 In one embodiment, the first support assembly 2 is arranged at the center of the base 1 to ensure the stability of the overall structure. Specifically, the base 1 is a square plate, the first support assembly 2 is arranged at the center of the square plate, and the second support assembly 3 is arranged on the line connecting the center of the square plate and the side plate.

[0060] It can be understood that by arranging the first support assembly 2 at the center of the base 1, it can ensure that the load is evenly distributed on the base 1, reducing structural deformation or damage caused by uneven load. At the same time, the evenly distributed load can improve the stability of the entire structure and reduce the risk of overturning due to local overload.

[0061] In one embodiment, the second fixing seat 32 is slidably connected to the second support member 31 along the height direction to adjust its own height during the sliding process. A fixing member is provided on the second fixing seat 32, which is connected to the second support member 31 and is configured to limit the position of the second fixing seat 32 on the second support member 31 to ensure the stability between the second fixing seat 32 and the second support member 31.

[0062] Specifically, a sliding groove is provided on the side of the second support member 31 facing away from the base 1, and the second fixing seat 32 is inserted into the sliding groove to achieve a sliding fit connection between the second fixing seat 32 and the second support member 31 in the height direction. The second support member 31 is also provided with a through opening 33 connected to the sliding groove, and the through opening 33 extends in the height direction. The fixing member passes through the through opening 33 and is connected to the second fixing seat 32, so that the fixing member can limit the position of the second fixing seat 32 on the second support member 31.

[0063] More specifically, the second support member 31 is provided with at least two through-holes 33 communicating with the sliding groove, and the two through-holes 33 are symmetrically arranged along the axial direction of the second support member 31. The number of the fixing members is consistent with the number of the through-holes 33, and the two fixing members are respectively arranged on the two through-holes 33 and are both connected to the second fixing seat 32.

[0064] It can be understood that in some embodiments, the fixing member is a rubber block, and the fixing member is inserted through the through-port 33 and abuts against the through-port 33. The position of the second fixing seat 32 on the second support member 31 is defined by the frictional force between the rubber block and the through-port 33.

[0065] In other embodiments, the fixing member includes a screw and a nut. The screw is inserted through the through-port 33 and connected to the second fixing seat 32, and the nut is screwed on the screw and abuts against the second support member 31. The position of the second fixing seat 32 on the second support member 31 is defined by tightening the nut against the second support member 31.

[0066] Refer to Figure 1 and Figure 2 In one embodiment, a fixing groove 34 is provided on the side surface of the second fixing seat 32 facing away from the base 1. The injector is inserted through the inside of the fixing groove 34, and the detachable connection of the injector is achieved through the fixing groove 34. Wherein, the outer side surface of the injector abuts against the inner surface of the fixing groove 34.

[0067] Specifically, the depth of the fixing groove 34 is greater than the thickness of the injector, so as to ensure that the injector can completely enter the fixing member through the fixing groove 34, so as to maximize the contact area between the injector and the second fixing seat 32, thereby ensuring that the injector can be detachably connected to the second fixing seat 32 while ensuring the stability of the injector on the second fixing seat 32.

[0068] Refer to Figure 4 The present application also provides a glue injection method for the glue injection jig in any of the above embodiments. The glue injection method includes:

[0069] Adjust the first fixing seat to a set angle with the base. Specifically, press the first fixing seat, so that the spherical universal joint drives the first fixing seat to rotate until the first fixing seat reaches the set angle with the base, thereby realizing the adjustment of the angle of the first fixing seat.

[0070] Place the special-shaped cover plate on the first fixing seat so that the special-shaped cover plate reaches the set working angle.

[0071] Place the injector on the second fixing seat and fix the injector through the fixing groove.

[0072] Adjust the second fixing seat to a set height with the base so that the injector will not be bent, ensuring the smoothness of subsequent glue injection.

[0073] Control the injector to inject glue into the special-shaped cover plate. Specifically, insert the glue injection needle of the injector into the glue injection port of the special-shaped cover plate, so that the injector can automatically inject glue into the special-shaped cover plate under the action of gravity.

[0074] The angle of the first fixing seat is adjusted according to the flow direction of the glue in the special-shaped cover plate until the glue is evenly distributed. Specifically, during the glue injection process, the operator can check the position of the glue in real time and adjust the angle of the first fixing seat according to the flow direction of the glue in the special-shaped cover plate to ensure that the glue is evenly distributed.

[0075] The glue injection method of the present application, by adjusting the angle of the first fixing seat of the glue injection jig on the first support member, and fixing the first fixing seat to the special-shaped cover plate, can make it possible to adjust the angle of the first fixing seat to a specified angle before glue injection in specific operations, thereby controlling the glue injection angle of the special-shaped cover plate and ensuring the consistency of the glue injection amount of the same batch of products. The angle of the first fixing seat can also be adjusted at any time during the glue injection process as needed, thereby adjusting the operating angle of the special-shaped cover plate, ensuring uniform distribution of glue, and ensuring the glue injection effect and the overall quality of the product.

[0076] In one embodiment, adjusting the angle of the first fixing seat according to the flow direction of the glue in the special-shaped cover plate includes:

[0077] Obtain the position of the glue in the special-shaped cover plate and determine the direction in which the glue is to flow.

[0078] When the direction in which the glue is to flow is consistent with the tilt direction of the first fixing seat, the angle of the first fixing seat remains unchanged, and the glue flows in the direction in which it is to flow.

[0079] When the flow direction of the glue is inconsistent with the tilt direction of the first fixing seat, pressure is applied to the first fixing seat to rotate the first fixing seat until the flow direction of the glue is consistent with the tilt direction of the first fixing seat, so that the glue can flow in the direction to be flowed.

[0080] In summary, when using the glue injection jig through the glue injection method of the present application, the special-shaped cover plate can be first placed on the first fixing seat, and the angle of the first fixing seat can be adjusted until the first fixing seat and the base reach the set angle, so that the special-shaped cover plate reaches the set working angle. Then, the glue injector is placed on the second fixing seat, and the height of the second fixing seat is adjusted to ensure that the glue injector will not be bent, guaranteeing the smoothness of subsequent glue injection. Then, the glue injection needle of the glue injector is inserted into the glue injection port of the special-shaped cover plate, enabling the glue injector to automatically inject glue into the special-shaped cover plate under the action of gravity. Moreover, during the glue injection process, the operator can view the position of the glue in real time and adjust the angle of the first fixing seat according to the flow direction of the glue in the special-shaped cover plate to ensure uniform distribution of the glue. The above glue injection method sets the first fixing seat with adjustable angle on the first support member and fixes the special-shaped cover plate with the first fixing seat, so that during specific operation, the angle of the first fixing seat can be adjusted to the specified angle before glue injection, thereby controlling the glue injection angle of the special-shaped cover plate and ensuring the consistency of the glue injection amount of products in the same batch. Also, the angle of the first fixing seat can be adjusted at any time according to requirements during the glue injection process, thereby adjusting the working angle of the special-shaped cover plate to ensure uniform distribution of the glue and guaranteeing the glue injection effect and the overall quality of the product.

[0081] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0082] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
