Description

Technical Field

[0001] This application relates to the field of adhesive technology, and more particularly to an adhesive tooling and adhesive method. Background Technology

[0002] In product manufacturing, multiple components can be bonded together using bonding fixtures to obtain the desired product, such as bonding two or more different composite material components into a multi-component composite material product. Bonding fixtures are devices or tools used to assist in positioning, supporting, and maintaining components in the correct position during the bonding process.

[0003] However, bonding components (such as composite material components) using existing bonding fixtures results in poor product quality (e.g., low positioning accuracy between components).

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention

[0005] This application provides an adhesive tooling and adhesive method to solve or alleviate one or more of the technical problems mentioned above.

[0006] As one aspect of the embodiments of this application, this application provides an adhesive tooling that relies on the shaping and positioning of a molding die and can be quickly assembled and disassembled. The adhesive tooling includes a tooling body, a connecting part, and a clamping part. The tooling body is connected to the clamping part through the connecting part. Positioning parts are provided at both ends of the tooling body, and the clamping part is used to fix it to the object to be bonded.

[0007] The molding die is provided with a positioning interface, and the molding die is used to hold the product body that has not been demolded;

[0008] In the assembled state, the positioning part of the bonding fixture is locked to the positioning interface of the molding mold, thereby fixing the bonding fixture on the molding mold; when the bonding fixture is fixed on the molding mold, the object to be bonded approaches the product body and is bonded to the bonding area of ​​the product body by applying adhesive.

[0009] Optionally, the bonding fixture further includes a linear slide rail and a limiting block, wherein the linear slide rail is fixed on the fixture body and the limiting block is fixed at one end of the linear slide rail;

[0010] The connecting part is slidably mounted on the linear slide rail to move the object to be bonded; the limiting block is used to limit the maximum movement position of the connecting part on the linear slide rail to determine the target position of the object to be bonded.

[0011] Optionally, the connecting part is provided with a locking bolt;

[0012] Correspondingly, the limiting block is provided with a screw hole;

[0013] The screw hole is locked with the locking bolt. Under the action of external force, the relative position of the object to be bonded and the main body of the product can be adjusted by adjusting the locking force of the locking bolt and the limiting block.

[0014] Optionally, the connecting portion is provided with a guide hole;

[0015] The limiting block is equipped with guide posts;

[0016] The guide hole corresponds to the position of the guide post and is used to allow the guide post to pass through.

[0017] Optionally, the bonding fixture further includes:

[0018] A lifting block, which is fixed to the main body of the tooling, and the lifting block is in the shape of an annular ring.

[0019] Optionally, the clamping part is made of medium carbon steel.

[0020] As another aspect of the embodiments of this application, this application provides a drilling method for bonding an object to be bonded to a product body using an adhesive fixture. The adhesive fixture includes a fixture body, a connecting part, a clamping part, and a linear slide rail. The fixture body is connected to the clamping part through the connecting part. The linear slide rail is fixed to the fixture body and allows the connecting part to slide. The product body is disposed in a molding die, and the molding die is provided with a positioning interface. The method includes:

[0021] The object to be bonded is fixed on the clamping part of the bonding fixture, which is provided with a positioning part;

[0022] Based on the positioning part and the positioning interface, the bonding fixture is fixed on the molding die;

[0023] The object to be bonded is moved along the linear slide rail to the bonding area of ​​the product body.

[0024] When the object to be bonded is located in the bonding area of ​​the product body, the object to be bonded is bonded to the bonding area of ​​the product body, and then the object to be bonded is separated from the bonding fixture.

[0025] Optionally, the bonding fixture further includes a limiting block connected to one end of the linear slide rail, and the limiting block is provided with a screw hole; the connecting part is provided with a locking bolt; the method further includes:

[0026] The relative position of the object to be bonded and the main body of the product can be adjusted by adjusting the tightening force of the locking bolt and the screw hole.

[0027] The embodiments of this application employing the above-described technical solution may have the following advantages:

[0028] A positioning interface is set in the molding mold, and a positioning part is set in the bonding fixture accordingly. By engaging the positioning interface with the positioning part, the bonding fixture can be quickly fixed on the molding mold. When it is necessary to bond the object to be bonded to the product body, the object to be bonded can be directly bonded to the product body that has not been demolded in the molding mold by the bonding fixture fixed on the molding mold. The advantages of doing so are: (1) Bonding can be carried out in the state where the product body has not been demolded, without the need to demold the product body (the product body is easy to deform after demolding, resulting in poor bonding accuracy). This can improve the relative position accuracy between the object to be bonded and the product body during bonding, thereby improving the bonding accuracy and the quality of the bonded items. (2) Bonding can be carried out when the product body has not been demolded. High-precision positioning and bonding of the product body and the object to be bonded can be achieved by the bonding fixture and the molding mold. Therefore, it is not necessary to rely on other fixtures (such as positioning fixtures) to position the product body and the object to be bonded after demolding. This can reduce the cost of fixture manufacturing and simplify the bonding operation process, thereby improving the bonding efficiency. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The application will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] The following provides a definition of the terminology used in this application.

[0053] Bonding fixtures: Devices used to hold parts in a specific position and maintain their position during manufacturing or assembly processes so that processes such as bonding or welding can be performed.

[0054] Composite materials: Materials composed of two or more different types of materials. Composite materials can consist of two parts: a matrix and a reinforcement.

[0055] Demolding: The process of removing a finished workpiece or product from a mold. In manufacturing processes, molds or models are used to shape or form objects. Once the workpiece has completed its shaping or processing within the mold, it needs to be removed from the mold; this process is called demolding.

[0056] Molding mold: A tool or device used to process raw materials into a desired shape. Molding molds can be made of metal, plastic or other materials, and have a specific shape and structure. They are used in the manufacturing process to process raw materials (such as composite materials) into finished products of the desired shape and size.

[0057] Mold parting surface: Inside the mold, it is the boundary or dividing line between two or more surfaces used to separate the mold and remove the molded product. The parting surface determines the separation position of the mold during the demolding process, ensuring that the molded product can be smoothly removed from the mold while maintaining the structural integrity of the mold and production efficiency.

[0058] To facilitate understanding of the technical solutions provided in the embodiments of this application by those skilled in the art, the relevant technologies are described below:

[0059] When bonding products (such as composite material products), the main body of the product can be demolded first, and then the main body of the product can be positioned by tooling. Then, tooling is designed to limit the position according to the positional relationship between the parts. The above method has the following shortcomings: (1) The main body of the product is easily deformed after demolding, resulting in poor positioning accuracy in the bonding process, which in turn leads to poor components after bonding (such as weak adhesion); (2) The tooling design cost is high; (3) The product and tooling need to be repeatedly adapted, resulting in low work efficiency; (4) The adaptation and transfer operation of the components to be bonded and the product is complicated; (5) It is difficult to control the bonding thickness during the bonding process.

[0060] Therefore, this application provides a bonding fixture and a bonding technology solution based on the bonding fixture. In this technical solution, (1) the bonding fixture is placed on the mold parting surface through the positioning interface reserved in the mold, and the bonding operation is performed in the product before demolding. The advantages of doing so are: it can solve the problem of poor bonding positioning accuracy caused by deformation after product demolding, and at the same time, the bonding thickness is controlled according to the structure of the bonding fixture, which improves the bonding accuracy of multiple parts of the product and simplifies the operation process. (2) Bonding is performed in the product body before demolding, which can improve the relative position accuracy between the bonded parts. (3) Bonding is performed in the product body before demolding, which eliminates the need for secondary positioning and reduces the tooling manufacturing cost. (4) The tooling and mold positioning accuracy is high, which ensures the bonding position accuracy. (5) The linear slide rail movement operation is convenient and can improve the work efficiency. (6) By controlling the bonding gap between the product and the parts through the limit block and applying pressure during the bonding process using the locking bolt, the quality of the bonded components can be effectively controlled. (7) It can be used for mass production of products, and the product manufacturing cycle can be reduced by improving the efficiency of the bonding process. See below for details.

[0061] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0062] Example 1

[0063] like Figures 1-6 As shown, this bonding fixture relies on the molding die (1) for shaping and positioning, and can be quickly assembled and disassembled. The bonding fixture may include: a fixture body, a connecting part 4, and a clamping part 5. The fixture body is connected to the clamping part 5 via the connecting part 4. Positioning parts 6 are provided at both ends of the fixture body, and the clamping part 5 is used to fix it to the object to be bonded. The molding die 1 is provided with a positioning interface 2, and the molding die 1 is used to hold the undemolded product body.

[0064] In the assembled state, the positioning part 6 of the bonding fixture is locked to the positioning interface 2 of the molding mold 1, thereby fixing the bonding fixture onto the molding mold 1. With the bonding fixture fixed on the molding mold 1, the object to be bonded approaches the product body and is bonded to the bonding area of ​​the product body by applying adhesive.

[0065] Bonding fixtures refer to tools, equipment, or devices used to assist, support, and position the objects to be bonded during the bonding process. Bonding fixtures ensure the position of the objects during bonding, allowing for precise and stable bonding to the product body.

[0066] The main body of the tooling can be shaped like an I-beam, such as... Figure 3 As shown, the main body of the tooling may include two parallel strip plates, which can be fixed by connecting plates (such as two plates), and the connecting plates are perpendicular to the two strip plates. It should be noted that the shape of the main body of the tooling can be designed according to actual conditions and is not limited here. The main body of the tooling can be welded from materials such as Q235-B square tubing.

[0067] The connecting part can be a columnar body made of Q234-B square tube, and the connecting part can be fixedly connected to the clamping part by means of pins and bolts.

[0068] The clamping part can be made of S45C material. In the assembled state, the clamping part can be used to fix the objects to be bonded. It should be noted that the shape of the clamping part and the fixing method between the clamping part and the objects to be bonded can be set according to actual conditions, such as being designed according to the outer contour of the objects to be bonded. In some embodiments, such as... Figure 3 As shown, the clamping part can be a rectangular plate, and there can be two clamping parts, which can be respectively located near both ends of the tooling body. The clamping parts can be provided with corresponding bolts, screw holes, etc., to fix the object to be bonded below the clamping part.

[0069] The positioning part can be a component used to ensure proper alignment between the bonding tooling and the molding die during assembly. The positioning part can be a rectangular or square positioning block, such as... Figure 3 As shown, corresponding positioning parts can be set at both ends of the two strip plates of the tooling body. The positioning parts can be fixedly connected to the strip plates by means of pins and bolts.

[0070] A molding die can be a tool or device used to process materials (such as composite materials) into a desired shape. The molding die can be of different types, such as injection molds, die-casting molds, extrusion molds, and compression molds. It should be noted that the material and shape of the molding die can be set according to actual conditions, such as the shape and specifications of the main body of the product to be manufactured, and are not limited here.

[0071] A positioning interface can be a connecting device used to ensure the accurate positioning of the bonding tooling and the molding die during assembly. The design (e.g., shape, size) of the positioning interface can be adapted to the positioning part of the bonding tooling. For example, the positioning interface can be a corresponding protrusion (e.g., a flange), and correspondingly, the positioning part can be a square block with a corresponding groove, the protrusion and the groove being able to engage and be fixed together. Specifically, as... Figure 3As shown, the positioning interface can be a positioning post set on the parting surface of the molding die, and the positioning part can be provided with a groove or the like that conforms to the size and shape of the positioning post. In addition, the positioning post can also be provided with corresponding positioning holes, which can allow bolts or the like on the positioning part to pass through, thereby further fixing the bonding tooling to the molding die.

[0072] The product body can be the main part of the product to be manufactured, such as the body of a car body. The object to be bonded can be an object that needs to be bonded to the corresponding bonding area on the product body.

[0073] The adhesive coating can be a glue or adhesive used to bond the object to be bonded to the product body. The type of adhesive coating can be selected according to the actual situation. For example, when both the product body and the object to be bonded are composite material products, the adhesive coating can be epoxy resin glue, polyurethane glue, acrylic glue, cyanoacrylate glue, etc.

[0074] For example, to bond an object to the product body, the specific process can be as follows: The bonding fixture is placed on the parting surface of the molding mold through the positioning interface of the molding mold. After placement, the bonding fixture is locked to the molding mold using bolts or similar means (screw holes or bolts can be provided at corresponding positions on the bonding fixture and the molding mold to lock them together). While the product body is still in the mold, the object to be bonded, fixed in the clamping part, is pushed to the bonding area for sanding and fitting, and then adhesive is applied to bond the object to the product body.

[0075] In this embodiment, a positioning interface is provided in the molding mold, and a positioning part is provided in the bonding fixture accordingly. By engaging the positioning interface with the positioning part, the bonding fixture can be quickly fixed on the molding mold. When it is necessary to bond the object to be bonded to the product body, the object to be bonded can be directly bonded to the product body in the molding mold without demolding by using the bonding fixture fixed on the molding mold. The advantages of doing so are: (1) Bonding can be performed while the product body is still in the molded state, without demolding the product body (the product body is easily deformed after demolding, resulting in poor bonding accuracy). This can improve the relative positional accuracy between the object to be bonded and the product body during bonding, thereby improving the bonding accuracy and the quality of the bonded items. (2) Bonding can be performed while the product body is still in the mold. High-precision positioning and bonding of the product body and the object to be bonded can be achieved by using the bonding fixture and the molding mold. This eliminates the need to use other fixtures (such as positioning fixtures) to position the product body and the object to be bonded after demolding. This can reduce the cost of fixture manufacturing and simplify the bonding process, thereby improving bonding efficiency.

[0076] In an optional embodiment, the bonding fixture further includes a linear slide rail 7 and a limiting block 8, wherein the linear slide rail 7 is fixed to the fixture body, and the limiting block 8 is connected to one end of the linear slide rail 7. The connecting portion 4 is slidably mounted on the linear slide rail 7 to move the object to be bonded. The limiting block 8 is used to limit the maximum movement position of the connecting portion 4 on the linear slide rail 7 to determine the target position of the object to be bonded.

[0077] The linear guide rail provides a smooth and precise linear motion track for the connecting part on the fixture body. Since the connecting part can be fixedly connected to the clamping part, with the object to be bonded already fixed on the clamping part, the position of the object to be bonded can be quickly adjusted by sliding the connecting part. It should be noted that the direction of movement provided by the linear guide rail to the connecting block is the bonding direction of the object to be bonded (i.e., the direction in which bonding pressure is applied). Multiple linear guide rails can be used, such as... Figure 3 As shown, four linear slide rails can be provided on the main body of the tooling. Specifically, corresponding linear slide rails are provided at the two strip plates of the main body of the tooling near their ends. The linear slide rails can be connected and fixed to the main body of the tooling by bolts and pins.

[0078] The limiting block can be made of S45C material, and it can be fixedly connected to the main body of the tooling via bolts or the like. The limiting block can be a component used to limit the range of motion of the connecting part, and its configuration can be set according to the bonding direction, etc. For example, such as... Figure 3 As shown, a corresponding limiting block can be set at one end of each linear guide. For example, a limiting block can be set in the direction of the first end a, which is close to the linear guide (the linear guide is located near the first end a on the tooling body).

[0079] In the above optional embodiments, by slidingly mounting the connecting part on the linear slide rail, the object to be bonded can be moved conveniently and quickly, bringing it closer to the bonding area on the product body, thus improving operational efficiency. Furthermore, by limiting the movement of the connecting part on the linear slide rail using a limiting block, the target position of the object to be bonded can be accurately controlled, thereby precisely controlling the bonding gap between the product body and the object to be bonded, and ensuring the bonding thickness between the product body and the object to be bonded.

[0080] In an optional embodiment, the connecting part 4 is provided with a locking bolt 41, and correspondingly, the limiting block 8 is provided with a screw hole 81. The screw hole 81 is locked with the locking bolt 41, and under external force, the position of the object to be bonded is adjusted by adjusting the locking force between the locking bolt and the limiting block.

[0081] The locking bolt 41 can be placed in the connection part in a direction parallel to the direction of the linear slide rail, such as... Figure 5 , Figure 6 As shown, since the linear guide rail is horizontal, the locking bolt 41 should also be placed horizontally in the connecting part. Correspondingly, the screw hole 81 should be a horizontal hole. In the working state, by adjusting the locking force of the locking bolt 41 and the screw hole 81 (e.g., tightening or loosening), the distance between the connecting part and the limiting block can be adjusted, thereby adjusting the relative position of the object to be bonded and the product body to apply different bonding pressures to the object to be bonded.

[0082] In the above optional embodiments, by adjusting the tightening force of the locking bolt and the screw hole, the bonding pressure applied to the object to be bonded can be adjusted, thereby adjusting the bonding thickness between the object to be bonded and the product body, and improving the quality of the obtained bonding assembly (the combination of the product body and the product to be bonded).

[0083] In an optional embodiment, the connecting part 4 is provided with a guide hole 42, and the limiting block 8 is provided with a guide post 82. The guide hole 42 and the guide post 82 are positioned correspondingly to allow the guide post 82 to pass through. The guide post 82 can be fixed to the limiting part by bolts or other means.

[0084] In the above optional embodiments, by setting guide posts on the limiting block and guide holes on the connecting part, that is, by adding a guiding mechanism between the limiting part and the connecting part, the positioning accuracy between the connecting part and the limiting part can be improved, thereby improving the smoothness of the movement of the connecting part on the linear guide rail.

[0085] In an optional embodiment, the bonding fixture further includes a lifting block 9, which is fixed to the fixture body and is annular in shape.

[0086] The lifting blocks can be made of Q235-B material, and there can be multiple lifting blocks, such as four. Each lifting block can be fixed to the main body of the tooling by welding. The lifting blocks can be used to lift and suspend the bonding tooling, and the bonding tooling can be moved effectively through the lifting blocks.

[0087] In an optional embodiment, the clamping part is made of medium carbon steel.

[0088] Example 2

[0089] Figure 7 A flowchart illustrating the bonding method according to Embodiment 2 of this application is shown schematically.

[0090] This bonding method is used to bond tooling (such as...) Figure 1(As shown) The object to be bonded is bonded to the product body. The bonding fixture includes a fixture body, a connecting part, a clamping part, and a linear slide rail. The fixture body is connected to the clamping part through the connecting part. The linear slide rail is fixed to the fixture body and allows the connecting part to slide. The product body is disposed in a molding die, and the molding die is provided with a positioning interface. The method may include steps S700 to S706, wherein:

[0091] Step S700: Fix the object to be bonded on the clamping part of the bonding fixture, wherein the bonding fixture is provided with a positioning part;

[0092] Step S702: Based on the positioning part and the positioning interface, fix the bonding fixture on the molding die;

[0093] Step S704: Move the connecting part along the linear slide rail to move the object to be bonded so that the object to be bonded is located in the bonding area of ​​the product body.

[0094] Step S706: When the object to be bonded is located in the bonding area of ​​the product body, the object to be bonded is bonded to the bonding area of ​​the product body, and then the object to be bonded is separated from the bonding fixture.

[0095] In this embodiment, a positioning interface is provided in the molding mold, and a positioning part is provided in the bonding fixture accordingly. By engaging the positioning interface with the positioning part, the bonding fixture can be quickly fixed on the molding mold. When it is necessary to bond the object to be bonded to the product body, the object to be bonded can be directly bonded to the product body in the molding mold without demolding by using the bonding fixture fixed on the molding mold. The advantages of doing so are: (1) Bonding can be performed in the state where the product body is not demolded, without demolding the product body (the product body is easy to deform after demolding, resulting in poor bonding accuracy), which can improve the relative position accuracy between the object to be bonded and the product body during bonding, thereby improving the bonding accuracy. (2) Bonding can be performed when the product body is not demolded, and high-precision positioning and bonding of the product body and the object to be bonded can be achieved by using the bonding fixture and the molding mold, so that the product body and the object to be bonded after demolding do not need to be positioned by other fixtures (such as positioning fixtures), which can reduce the fixture manufacturing cost and simplify the bonding operation process, thereby improving the bonding efficiency.

[0096] In an optional embodiment, the bonding fixture further includes a limiting block connected to one end of the linear slide rail, the limiting block having a screw hole, and the connecting portion having a locking bolt. The method may further include adjusting the relative position of the object to be bonded and the product body by adjusting the locking force between the locking bolt and the limiting block.

[0097] In the above optional embodiments, by adjusting the tightening force of the locking bolt and the screw hole, the bonding pressure applied to the object to be bonded can be adjusted, thereby adjusting the relative position of the object to be bonded and the product body, as well as the bonding thickness between the object to be bonded and the product body, and improving the quality of the obtained bonding assembly (the combination of the product body and the product to be bonded).
