[0022] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0023] Existing splicing fixtures suffer from low splicing accuracy and unstable splicing quality during use. To address these issues, this application provides a splicing fixture that employs a high-precision positioning clamp to accurately position two workpieces, ensuring positional accuracy during splicing; and utilizes a pressure application device and a pressure detection device to provide uniform and appropriate pressure during the splicing process, guaranteeing the strength of the splice, thereby improving both the accuracy and quality of the splicing.
[0024] This application uses the automotive trim processing application scenario as an example to introduce the structure and usage of the splicing fixture in this application. The splicing fixture provided in this application is not only suitable for automotive trim production, but also for application scenarios involving the splicing of other types of workpieces, specifically:
[0025] A splicing fixture includes a worktable 1, on which a support mechanism 2, a positioning mechanism 3, a clamping mechanism 4, and a splicing mechanism 5 are mounted. The pressing surface of the clamping mechanism 4 is movably positioned opposite to the supporting surface of the support mechanism 2. The positioning mechanism 3 is arranged around the edge of the support mechanism 2. The splicing mechanism 5 is movably positioned on one side of the support mechanism 2. When the splicing mechanism 5 is close to the support mechanism 2, it corresponds to the position of the workpiece to be bonded on the support mechanism 2, and is used to press and splice the workpiece. The splicing mechanism 5 is equipped with a pressure detection device 51 for detecting the pressure during the splicing process. After the support mechanism 2 supports the trim strip to be spliced, the positioning mechanism 3 accurately positions the trim strip to ensure the positional accuracy during splicing. Then, the clamping mechanism 4 precisely positions and clamps the trim strip onto the support mechanism 2, and the splicing mechanism 5 presses and splices the trim strip. Furthermore, the pressure detection device 51 on the splicing mechanism 5 can detect the pressing pressure in real time, so as to adjust the pressure during the pressing process, ensure the splicing firmness, and thus improve the splicing accuracy and quality.
[0026] In some embodiments, the support surface of the support mechanism 2 is strip-shaped; the positioning mechanism 3 includes a limiting post 31 and a limiting end 32; the limiting end 32 is disposed at the end of the support surface of the support mechanism 2; the limiting posts 31 are sequentially spaced along both sides of the support surface of the support mechanism 2. By disposing the limiting end 32 at the end of the support surface of the support mechanism 2, the trim strip can be limited at the end of the support surface; and by sequentially spaced the limiting posts 31 along both sides of the support surface, the trim strip can be limited on the side of the support surface, thereby effectively positioning and limiting the trim strip on the support mechanism 2.
[0027] In some embodiments, the clamping mechanism 4 includes a pre-clamping device 41 and a clamping positioning device 42. The pressing height of the pre-clamping device 41 is higher than that of the clamping positioning device 42. That is, after the trim strip on the support mechanism 2 is pre-clamped by the pre-clamping device 41, the trim strip is clamped and positioned by the clamping positioning device 42. The secondary clamping can apply sufficient clamping force so that the trim strip will not shift or loosen during splicing and will remain stable, thereby achieving a more effective positioning and clamping effect.
[0028] In some embodiments, the pre-clamping device 41 and the clamping positioning device 42 are pneumatic clamps or manual clamping clamps. Using pneumatic clamps or manual clamping clamps as clamping devices can meet the needs of clamping operations in different scenarios.
[0029] In some embodiments, the pressing and positioning device 42 includes at least two sets of pressing blocks 421 and a first cylinder 422; the fixed end of the first cylinder 422 is connected to the worktable 1, and the movable end of the first cylinder 422 is connected to the pressing block 421; the first cylinders 422 are arranged sequentially at intervals along the edge of the support surface of the support mechanism 2. The pressing blocks 421 and the first cylinders 422 form a pressing and positioning assembly, and multiple pressing and positioning assemblies constitute the pressing and positioning device 42. By arranging these multiple pressing and positioning assemblies sequentially at intervals along the edge of the support surface of the support mechanism 2, the trim strip can be effectively positioned and pressed.
[0030] In some embodiments, the splicing mechanism 5 includes a movable member 52, a pressing head 53, a pressure detection device 51, a second cylinder 54, and a slide rail 55; the slide rail 55 is disposed on the worktable 1; the movable member 52 is slidably disposed on the slide rail 55; the fixed end of the second cylinder 54 is connected to the side of the movable member 52 near the slide rail 55; the movable end of the second cylinder 54 is connected to the pressing head 53; and the pressure detection device 51 is disposed on the side of the pressing head 53 away from the second cylinder 54. By disposing of the movable member 52 on the slide rail 55, when splicing is required, the movable member 52 can be moved closer to the support mechanism 2, and the trim strips are pressed and spliced by the second cylinder 54 and the pressing head 53. A pressure sensor is also used as the pressure detection device 51 to detect the pressure of the pressing head 53 during the pressing process, thereby controlling the pressure during the pressing and splicing process. After splicing is completed, the movable member 52 can be moved away from the support mechanism 2, and the spliced trim strips can be removed.
[0031] In some embodiments, a suction cup 56 is provided inside the pressure head 53; the suction nozzle of the suction cup 56 is disposed on the pressing surface of the pressure head 53. By providing a suction cup 56 inside the pressure head 53, while the pressure head 53 applies pressure to the trim strip, the suction cup 56 also adsorbs the trim strip, thereby achieving a more effective pressing effect on the trim strip.
[0032] In some embodiments, the movable member 52 is provided with a guide rod 57; one side of the pressure head 53 is movably connected to the guide rod 57. By providing the guide rod 57 on the movable member 52, the guide rod 57 guides the movement of the pressure head 53, reducing the shaking of the pressure head 53 during movement, thereby improving the pressing effect on the trim strip.
[0033] In some embodiments, a side-pushing device 6 is also included; the side-pushing device 6 is used to move the workpiece on the worktable 1. By setting the side-pushing device 6 to move the workpiece on the worktable 1, for example when splicing two trim strips by tooling, the side-pushing device 6 can be used to move one trim strip towards the other trim strip, so that the two trim strips are close together before being pressed and spliced.
[0034] In some embodiments, an adhesive application mechanism 7 is further included; the adhesive application mechanism 7 is disposed on one side of the support mechanism 2 and corresponds to the position on the support mechanism 2 where the workpiece is to be bonded. By providing the adhesive application mechanism 7, the adhesive can be applied to the part of the trim strip to be spliced and the adhesive application can be limited.
[0035] The following embodiments are preferred embodiments of the above implementation methods.
[0036] Please refer to Figure 1 and Figure 2A splicing fixture includes a workbench 1, on which a support mechanism 2, a positioning mechanism 3, a clamping mechanism 4, a splicing mechanism 5, a side-pushing device 6, and an adhesive applicator 7 are mounted. The workbench 1 also includes a start button 11, an indicator light 12, a boom 13, and a pressure reducing valve 14. The start button 11 controls the start and stop of the fixture; the indicator light 12 displays the current working status of the fixture; the boom 13 connects to relevant equipment; and the pressure reducing valve 14 controls the pressure of each cylinder. The clamping surface of the clamping mechanism 4 is movably positioned opposite the support surface of the support mechanism 2. The positioning mechanism 3 is positioned around the edge of the support mechanism 2. The splicing mechanism 5 is movably positioned on one side of the support mechanism 2. When the splicing mechanism 5 is close to the support mechanism 2, it corresponds to the position of the workpiece to be bonded on the support mechanism 2, and is used to press and splice the workpiece. The splicing mechanism 5 is equipped with a pressure detection device 51 to detect the pressure during the splicing process. The side-pushing device 6 is used to move the workpiece on the worktable 1; the glue-applying mechanism 7 is located on one side of the support mechanism 2 and corresponds to the position of the workpiece to be glued on the support mechanism 2.
[0037] In the application scenario of bonding automotive corner windows, the tooling is mainly used to splice two trim strips, therefore the support surface of the support mechanism 2 forms a strip shape that matches the shape of the trim strip; such as Figure 1 As shown, the support mechanism 2 includes a support structure for supporting the upper trim strip and a support structure for supporting the lower trim strip. The support surfaces of both support structures are strip-shaped and converge at the splicing position. The support structure can be composed of multiple support blocks or a single contour support block.
[0038] The positioning mechanism 3 includes limiting posts 31 and limiting ends 32; the limiting ends 32 are disposed at the end of the supporting surface of the supporting mechanism 2; the limiting posts 31 are arranged sequentially at intervals along both sides of the supporting surface of the supporting mechanism 2. Figure 1 As shown, two limiting posts 31 can be set as a group and distributed on both sides of the support surface, or a single limiting group can be set as a group on one side of the support surface, and multiple groups of limiting posts 31 can be arranged sequentially at intervals along the side edge of the support surface; two limiting ends 32 are respectively set at the ends of the two separated support structures.
[0039] The clamping mechanism 4 includes a pre-clamping device 41 and a clamping positioning device 42. The pre-clamping device 41 and the clamping positioning device 42 are either pneumatic clamps or manual clamping clamps. For example, in this embodiment, the pre-clamping device 41 is a manual clamping clamp, and the clamping positioning device 42 is a pneumatic clamp composed of a clamping block 421 and a first cylinder 422. The fixed end of the first cylinder 422 is connected to the worktable 1, and the movable end of the first cylinder 422 is connected to the clamping block 421. Simultaneously, the clamping positioning device 42 includes multiple sets of pneumatic clamps; these multiple sets of pneumatic clamps are sequentially spaced along the edge of the support surface of the support mechanism 2.
[0040] Please refer to Figure 3 and Figure 4 The splicing mechanism 5 includes a movable component 52, a pressure head 53, a pressure detection device 51, a second cylinder 54, and a slide rail 55. A pressure sensor is used as the pressure detection device 51. The slide rail 55 is mounted on the worktable 1. The movable component 52 is slidably mounted on the slide rail 55. The fixed end of the second cylinder 54 is connected to the side of the movable component 52 closest to the slide rail 55. The movable end of the second cylinder 54 is connected to the pressure head 53. The pressure detection device 51 is located on the side of the pressure head 53 away from the second cylinder 54. A suction cup 56 is also provided inside the pressure head 53; the suction nozzle of the suction cup 56 is located on the pressing surface of the pressure head 53. To improve the stability of the pressure head 53 during movement, the movable component 52 is provided with a guide rod 57; one side of the pressure head 53 is movably connected to the guide rod 57.
[0041] The workflow for the above-mentioned assembly fixture is as follows:
[0042] S1. After docking the aircraft insert 13 with the relevant equipment, place the two upper and lower trim strips to be spliced on the support surface of the support mechanism 2 respectively, and position them by the limiting end 32 and the limiting post 31; then, after the upper and lower trim strips are pre-pressed by the pre-pressing device 41, the first cylinder 422 of the pressing and positioning device 42 is activated to clamp and position the upper and lower trim strips by the pressure block 421.
[0043] When splicing, it is necessary to select an appropriate splicing method according to the material, shape and design requirements of the trim strip. For example, when splicing by adhesive, a connecting piece is placed at the splicing point of the upper and lower trim strips and glue is applied by the glue application mechanism 7.
[0044] S2. Perform the splicing operation. The upper trim strip is moved as a whole by the side push device 6. During the movement, the pressure of the cylinder of the side push device 6 can be adjusted by the pressure reducing valve 14 to splice the upper trim strip with the lower trim strip.
[0045] S3. The splicing mechanism 5 uses a cylinder to push the moving part 52 on the slide rail 55 to the limit position of the slide rail 55 and stop it. At this time, the pressure head 53 is set above the splicing point. The second cylinder 54 presses down the pressure head 53 to apply pressure to the splicing point. During the pressing process, the pressure can be adjusted by the pressure reducing valve 14. The pressing action is maintained for a period of time to ensure that the splicing is firm. By applying a certain pressure to the splicing point, the splicing effect can be enhanced, ensuring that the splicing point fits tightly and improving the splicing firmness and sealing.
[0046] S4, release the splicing mechanism 5 and clamping mechanism 4, and remove the spliced trim strip. For example, after a 5-second delay, the corresponding mechanism will automatically open, and then the workpiece can be manually removed.
