Description

Technical Field

[0001] This invention relates to a potting process, and more specifically, to a method for potting and fixing tubes. Background Technology

[0002] The potting process is a crucial manufacturing procedure, as its quality directly impacts the product's appearance, electrical properties, and mechanical characteristics. Recent years have revealed a series of potting quality issues, indicating a very serious problem with the potting quality of assembled components.

[0003] Currently, during the glue-filling operation of tubes, the bending of the tubes causes them to twist, increasing their flatness. This results in glue and tubes protruding above the product surface during the glue-filling process, affecting product quality. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a method for fixing tubes with glue, which reduces the flatness requirements of the tubes after bending, thereby reducing the bending difficulty of the tubes. During the glue-filling process, the glue and the tubes will not protrude above the product surface, thus ensuring the quality of the product.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a method for fixing tubes with adhesive, comprising the following steps:

[0006] S1, Inject the glue into the grooves on the glued product so that the bottom of the groove is covered with a layer of base glue;

[0007] S2, Insert the tubular workpiece into the groove;

[0008] S3, press the clamping fixture onto the tubular workpiece so that the highest point of the tubular workpiece is lower than the surface of the glued product;

[0009] S4, base adhesive cured;

[0010] S5, Remove the clamping fixture;

[0011] S6. Inject side glue into both sides of the tubular workpiece at the opening of the groove to form side glue, and smooth the glue surface to make it flat.

[0012] S7, side adhesive cured.

[0013] When applying adhesive to tubular workpieces, first apply a layer of primer to the bottom of the groove, then install the tubular workpiece into the groove. Use a clamping fixture to press and position the workpiece, preventing it from protruding from the groove opening. Even if the tubular workpiece twists due to bending, it will remain within the groove, reducing the difficulty of bending. After the primer cures, apply and cure the side adhesive to further secure the workpiece, ensuring a good adhesive fixation effect.

[0014] The tube-type glue-filling and fixing method disclosed in this patent application reduces the flatness requirements of the tube after bending, thereby reducing the bending difficulty of the tube workpiece. During the glue-filling process, the glue and the tube workpiece will not protrude above the product surface, ensuring the quality of the product.

[0015] Preferably, before S1, a masking pad is applied to the surface of the glued product, and the grooves of the glued product on the masking pad are cut out to form a hollow; after S7, the masking pad applied to the surface of the glued product is removed.

[0016] Masking pads are applied to the surface of the product to prevent glue from sticking to the surface during the glue-pouring process.

[0017] Preferably, the shielding pad is made of tape.

[0018] Adhesive tape is convenient to use as a masking pad.

[0019] Preferably, in step S1, after opening the glue container, the glue is first placed in an oven for heating, and then the heated glue is injected into the groove.

[0020] Heating increases the fluidity of the glue, making it easier to flow to various locations on the bottom surface after being poured into the trench.

[0021] As a preferred option, during the S3 process, any glue overflowing into the groove should be cleaned up promptly.

[0022] Remove any excess glue to prevent it from sticking to the surface of the glued product.

[0023] Preferably, the dispensing product is loaded onto a workbench for operation, and the workbench is equipped with several positioning pins to position the dispensing product.

[0024] The glue-dispensing product is loaded onto the workbench and positioned using locating pins, which facilitates the glue-dispensing operation.

[0025] Preferably, the clamping fixture includes a lifting seat and a pressure head. A clamping screw is connected between the lifting seat and the worktable. The pressure head is installed on the lifting seat, and the surface of the pressure head protrudes from the lifting seat. The pressure head presses against the tubular workpiece.

[0026] When the clamping fixture is in operation, the clamping screw is rotated so that the pressure head can be reliably clamped onto the tubular workpiece.

[0027] Preferably, the groove width of the glue-filled product gradually decreases from the bottom surface to the opening end.

[0028] This structural design ensures that after the adhesive is poured and cured in the groove, it forms a structure that is smaller at the top and larger at the bottom, preventing the cured adhesive from detaching from the groove and ensuring the reliability of the pipe workpiece after it has been fixed with adhesive.

[0029] Preferably, in step S1, the dispensing product is loaded onto the movable seat, and a lifting support plate is installed on the movable seat, supporting the dispensing product on the support plate; after step S2, the movable seat moves to below the worktable, and a positioning hole adapted to the dispensing product is provided on the worktable, with several clamping fixtures installed on the edge of the positioning hole on the worktable; in step S3, the support plate rises, and the dispensing product is inserted into the positioning hole, so that the clamping fixtures press against the tubular workpiece; after step S5, the dispensing product descends together with the support plate, and the movable seat returns to its original position.

[0030] The adhesive product is loaded onto the support plate. After the primer is injected into the groove and the tubular workpiece is installed, it moves below the positioning hole. The support plate rises to allow the adhesive product to fit into the positioning hole. Several clamping fixtures press against the tubular workpiece, while a support piston cylinder pushes a support block outward to support the adhesive product. This method eliminates the need to adjust the clamping force of each clamping fixture, improving the consistency of the clamping force on the tubular workpiece. This results in a more even installation of the tubular workpiece within the groove, ensuring accurate installation. When the adhesive product is loaded onto the support plate, the support plate is separate from the worktable, and the clamping fixtures on the worktable do not interfere with the adhesive product. If the adhesive product were directly loaded onto the worktable, the position of the clamping fixtures would need to be moved during loading to prevent interference, and after loading, the clamping fixtures would need to be returned to their original positions and pressed against the tubular workpiece. Given the large number of clamping fixtures, this significantly impacts work efficiency. The clamping fixture in this application has a fixed setting that eliminates the need to adjust the position and clamping force, which facilitates operation and helps improve work efficiency.

[0031] Preferably, the worktable is provided with several positioning holes, and several clamping fixtures are installed on the edge of each positioning hole; several support mechanisms are installed on the edge of the positioning holes on the worktable, the support mechanism including a support piston cylinder and a support block, the support block being connected to the telescopic rod of the support piston cylinder; after S3, the telescopic rod of the support piston cylinder extends outward to support the support block on the surface of the glue-filled product, then the support plate descends and separates from the glue-filled product, and the support plate and the movable seat return to their original positions together; after S5, the support plate moves to below the positioning hole, after the support plate rises to its position, the support piston cylinder returns to its original position, then the glue-filled product is supported on the support plate and descends together with the support plate, and the movable seat returns to its original position.

[0032] The worktable is equipped with multiple positioning holes, allowing for simultaneous dispensing of multiple products, which improves work efficiency. After the support plate moves to the positioning hole, it rises to its position, pressing the clamping fixture onto the tubular workpiece. Then, the support piston cylinder extension rod extends outward, supporting the support block on the surface of the dispensing product. After this, the support plate and moving seat return to their original positions, allowing the next dispensing product to be loaded onto the support plate for base adhesive application and installation of the tubular workpiece.

[0033] Compared with the prior art, the beneficial effects of the present invention are: the tube-type glue-filling and fixing method of this patent application reduces the flatness requirements of the tube after bending, thereby reducing the bending difficulty of the tube workpiece. During the glue-filling process, the glue and the tube workpiece will not protrude above the product surface, thus ensuring the quality of the product. Attached Figure Description

[0043] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0044] Example 1: A method for fixing tubes with glue (see appendix) Figure 1 To be continued Figure 5 ), including the following steps:

[0045] S1. Inject the glue into the groove 2 on the glue-filling product 1, so that the bottom surface of the groove is covered with a layer of base glue with a thickness of 0.5mm-0.8mm. After opening the glue cap, put it in the oven and heat it for 2 hours. The oven temperature is controlled at 52℃. Then inject the heated glue into the groove.

[0046] S2, insert the tubular workpiece 3 into the groove, bend the tubular workpiece to form a ring structure, set the two ends of the tubular workpiece with risers 4, and extend upward out of the surface of the glued product.

[0047] S3, press the clamping fixture 5 onto the tubular workpiece so that the highest point of the tubular workpiece is lower than the surface of the glued product;

[0048] S4, base adhesive cured;

[0049] S5, Remove the clamping fixture;

[0050] S6. Inject side glue at a 45-degree angle on both sides of the tubular workpiece at the opening of the groove to form side glue, and smooth the glue surface to make it flat. Use a trowel 6 to smooth the glue surface. The width of the trowel is adapted to the width of the opening end of the groove. The end of the trowel has an arc-shaped structure, which has good adhesion to the surface of the tubular workpiece, thus ensuring the smoothing effect.

[0051] S7, side adhesive cured.

[0052] Before S1, a masking pad is applied to the surface of the product to be glued. The masking pad is made of self-adhesive tape, which makes it easy to apply to the surface of the product. The grooves of the product to be glued are cut out on the masking pad to create a cutout. After S7, the masking pad is removed from the surface of the product to be glued. During S3, any glue that overflows from the grooves is cleaned up promptly to prevent glue from sticking to the surface of the product to be glued.

[0053] The dispensing product is loaded onto the workbench 7 for operation. Several positioning pins 8 are set on the workbench to position the dispensing product. The edges of the dispensing product abut against the positioning pins for positioning. The clamping fixture includes a lifting seat 9 and a pressure head 10. The pressure head is mounted on the lifting seat, which has an L-shaped structure and a mounting groove 11. The upper part of the pressure head is installed in the mounting groove and secured to the lifting seat with screws. A clamping screw 12 connects the lifting seat and the workbench. The surface of the pressure head protrudes from the lifting seat, and the pressure head presses against the tubular workpiece. The end face of the pressure head has an arc-shaped structure, providing good contact with the surface of the tubular workpiece.

[0054] When applying adhesive to tubular workpieces, first apply a layer of primer to the bottom of the groove, then install the tubular workpiece into the groove. Use a clamping fixture to press and position the workpiece, preventing it from protruding from the groove opening. Even if the tubular workpiece twists due to bending, it will remain within the groove, reducing the difficulty of bending. After the primer cures, apply and cure the side adhesive to further secure the workpiece, ensuring a good adhesive fixation effect.

[0055] Example 2: A method for fixing tubes with glue (see appendix) Figure 6 To be continued Figure 8 The steps are similar to those in Example 1, with the main difference being that the groove width of the glue-filling product gradually decreases from the bottom to the opening end in this example. In S1, the glue-filling product is loaded onto the movable seat 13, and a lifting support plate 14 is installed on the movable seat, supporting the glue-filling product. Several positioning posts 15 are provided on the support plate, corresponding to the positioning holes on the glue-filling product. After S2, the movable seat moves below the worktable, and positioning holes 16 adapted to the glue-filling product are provided on the worktable. Several clamping fixtures are installed on the edges of the positioning holes on the worktable. The clamping fixtures include a fixed pressure seat 17 and a positioning pressure block 18. The fixed pressure seat is securely installed on the worktable, and the positioning pressure block has a downwardly extending protrusion 19 for clamping the tubular workpiece. In S3, the support plate rises, and the glue-filling product is inserted into the positioning hole, causing the clamping fixture to press against the tubular workpiece. After S5, the glue-filling product descends along with the support plate, and the movable seat returns to its original position.

[0056] Several positioning holes are provided on the worktable, and several clamping fixtures are installed on the edge of each positioning hole. Several support mechanisms 20 are installed on the edge of the positioning holes on the worktable. The support mechanism includes a support piston cylinder 21 and a support block 22. The support block is connected to the telescopic rod of the support piston cylinder. The upper surface of the front end of the support block is inclined to form a guide surface 23. After S3, the telescopic rod of the support piston cylinder extends outward to support the support block on the surface of the glued product. Then the support plate descends and separates from the glued product. The support plate and the moving seat return to their original positions together. After S5, the support plate moves to below the positioning hole. After the support plate rises to its position, the support piston cylinder returns to its original position. Then the glued product is supported on the support plate and descends with the support plate. The moving seat returns to its original position. Two guide rods 24 and a transmission screw 25 are installed under the worktable. The moving seat is threadedly connected to the transmission screw. The moving seat and the two guide rods are movably fitted together. One end of the transmission screw is connected to the output shaft of the drive motor. The drive motor 26 rotates and drives the moving seat to move. A lifting piston cylinder 27 is installed on the movable seat. The extension rod of the lifting piston cylinder is connected to the lifting plate 28. The lifting plate and the support plate are connected by a connecting rod 29, which passes through the movable seat. Other steps are the same as in Embodiment 1.

[0057] The adhesive product is loaded onto the support plate. After the primer is injected into the groove and the tubular workpiece is installed, it moves below the positioning hole. The support plate rises to allow the adhesive product to fit into the positioning hole. Several clamping fixtures press against the tubular workpiece, while a support piston cylinder pushes a support block outward to support the adhesive product. This method eliminates the need to adjust the clamping force of each clamping fixture, improving the consistency of the clamping force on the tubular workpiece. This results in a more even installation of the tubular workpiece within the groove, ensuring accurate installation. When the adhesive product is loaded onto the support plate, the support plate is separate from the worktable, and the clamping fixtures on the worktable do not interfere with the adhesive product. If the adhesive product were directly loaded onto the worktable, the position of the clamping fixtures would need to be moved during loading to prevent interference, and after loading, the clamping fixtures would need to be returned to their original positions and pressed against the tubular workpiece. Given the large number of clamping fixtures, this significantly impacts work efficiency. The clamping fixture in this application is fixed in place, eliminating the need to adjust its position and clamping force, thus simplifying operation and improving work efficiency. Multiple positioning holes on the worktable allow for simultaneous dispensing of multiple products, further enhancing efficiency. After the support plate moves to the positioning hole, it rises to its final position, pressing the clamping fixture onto the tubular workpiece. Then, the support piston cylinder's telescopic rod extends outward, supporting the support block on the surface of the dispensing product. Afterward, the support plate and moving seat return to their original positions, allowing the next dispensing product to be loaded onto the support plate for base adhesive application and installation of the tubular workpiece.
