[0044] Please see Figure 1 One embodiment of this application discloses a shaping device 100, applied in fields such as electronic device manufacturing and assembly, for shaping a frame (not shown) to ensure that the straightness and parallelism of each sidewall of the frame meet preset requirements. In this embodiment, the preset requirements are that the straightness and / or parallelism of each sidewall of the frame is less than or equal to 0.035. The shaping device 100 of this application will be described in detail below using the shaping of two adjacent sidewalls of the frame as an example.

[0045] Specifically, the shaping device 100 includes a support base 10, two inner pulling mechanisms 20, a slanting pushing mechanism 30, and a straight pushing mechanism 40. The support base 10 supports the frame. The two inner pulling mechanisms 20 are located on one side of the support base 10 and are used to pull the inner sidewall of the frame and move it outward to tighten the frame. The slanting pushing mechanism 30 is located on the other side of the support base 10 and is corresponding to one of the inner pulling mechanisms 20, and is used to push against the outer sidewall of the frame position pulled by the corresponding inner pulling mechanism 20. The straight pushing mechanism 40 is located on the support base 10 and adjacent to the slanting pushing mechanism 30, and is corresponding to the other inner pulling mechanism 20, and is used to push against the outer sidewall of the frame position tightened by the corresponding inner pulling mechanism 20. In this embodiment, with the center of the frame as the origin, movement towards the origin is movement inward, and movement away from the origin is movement outward.

[0046] It is understood that in some embodiments, the shaping device 100 is used to shape the four sidewalls of the frame. The frame includes four outer sidewalls and four inner sidewalls. The shaping device 100 includes a support 10, four inner pulling mechanisms 20, two oblique pushing mechanisms 30, and two straight pushing mechanisms 40. The support 10 is used to support the frame. The four inner pulling mechanisms 20 are disposed on one side of the support 10 and are used to pull the four inner sidewalls of the frame respectively and move them outward to tighten the frame. The two oblique pushing mechanisms 30 are disposed on the other side of the support 10 and are used to push against two opposite outer sidewalls of the frame. The two straight pushing mechanisms 40 are disposed on the support 10 and adjacent to the oblique pushing mechanisms 30 and are used to push against the other two opposite outer sidewalls of the frame to shape the frame.

[0047] The support base 10 has a support area 12 for supporting the frame; and two parallel mounting plates 14 are vertically arranged on the same side of the support base 10, the mounting plates 14 are used to mount the support base 10 on the machine base (not shown), wherein the support area 12 is located between the two mounting plates 14.

[0048] Please see Figure 2 , Figure 2 An exploded structural diagram of the support 10 and an internal pull mechanism 20 is shown. Each internal pull mechanism 20 includes an internal pull drive member 21, an internal pull member 22, a guide member 23, and an elastic member 24.

[0049] The inner pull drive member 21 is disposed on the lower surface of the support seat 10 and is connected to the guide member 23. The guide member 23 is slidably disposed within the support seat 10. The inner pull member 22 is elastically slidably disposed on the guide member 23 through the elastic member 24, so as to pull the inner sidewall of the frame to move elastically outward.

[0050] In this embodiment, the internal pull drive 21 is a cylinder.

[0051] The guide member 23 is provided with a groove 231 extending along a first direction and a limiting hole 232 communicating with the groove 231. In this embodiment, the first direction is the X-axis direction. The inner pull member 22 is slidably disposed in the groove 231. One end of the inner pull member 22 has an upwardly protruding holding part 221. The holding part 221 can extend into the bearing area 12 to pull the inner sidewall of the frame and move outward. The other end of the inner pull member 22 has a downwardly protruding abutting part 222 into the limiting hole 232. The abutting part 222 can slide in the limiting hole 232 along the first direction. The elastic member 24 is located in the limiting hole 232, and the two ends of the elastic member 24 abut against the abutting part 222 and the hole wall of the limiting hole 232 opposite to the abutting part 222, so that the inner pull member 22 can slide elastically.

[0052] In this embodiment, the elastic element 24 is a spring.

[0053] It is understood that the inner pull member 22 of the aforementioned inner pull mechanism 20 moves along the first direction, while the inner pull member 22 of the other inner pull mechanism 20 moves along the second direction, where the second direction is the Y-axis direction. Since the structures of the two inner pull mechanisms 20 are roughly the same, the structure of the other inner pull mechanism 20 will not be described in detail here.

[0054] It is understood that the shaping device 100, which has four inner pull mechanisms 20, is used to shape all four side walls of the frame. The inner pull members 22 of two opposing inner pull mechanisms 20 move along a first direction, while the inner pull members 22 of the other two opposing inner pull mechanisms 20 move along a second direction.

[0055] In this embodiment, since the frame is a rectangular structure with a long side and a short side, the guide 23 of the inner pull mechanism 20 corresponding to the long side of the frame is provided with four inner pull members 22, and the guide 23 of the inner pull mechanism 20 corresponding to the short side of the frame is provided with two inner pull members 22. The inner pull members 22 have a similar structure to the inner sidewall of the frame, which can make the movement of the corresponding side of the frame smooth and the force output point consistent, ensuring that the inner cavity of the frame and each contact point of the inner pull member 22 are subjected to uniform force and the inner cavity is not damaged.

[0056] It is understood that in other embodiments, the frame can be a square structure. In this case, the inner pull members 22 on the guide members 23 of the inner pull mechanism 20 provided on each side of the frame are the same, for example, there are two, three or four of them.

[0057] Please see Figure 3The inner pull mechanism 20 also includes a lower cover plate 25 and an upper cover plate 26. The lower cover plate 25 is disposed on the lower surface of the support seat 10, and the upper cover plate 26 is embedded in the support seat 10 and connected to the lower cover plate 25. The guide member 23 is movably positioned between the upper cover plate 26 and the lower cover plate 25. The lower cover plate 25 has a limiting hole 251 extending in a first direction. The guide member 23 has a sliding part 233 protruding downward into the limiting hole 251. The sliding part 233 can slide in the limiting hole 251 in the first direction, thereby limiting the movement distance of the guide member 23.

[0058] Please see Figure 4 The inclined push mechanism 30 includes an inclined push drive component 31, a fixed block 32, an inclined push plate 33, and a push plate 34.

[0059] A fixing block 32 is disposed on the upper surface of the support seat 10. A slanted push drive 31 is disposed on the fixing block 32. In this embodiment, the slanted push drive 31 is a cylinder. A slanted push plate 33 is disposed inside the fixing block 32 and can slide along a third direction perpendicular to the first and second directions respectively. One end of the slanted push plate 33 is connected to the slanted push drive 31. In this embodiment, the third direction is the Z-axis direction. A push plate 34 is disposed inside the fixing block 32 and can slide along the first direction. One end of the push plate 34 abuts against the other end of the slanted push plate 33. The other end of the push plate 34 can extend into the support area 12 and is disposed opposite to the inner pull member 22 of the corresponding inner pull mechanism 20. The slanted push drive 31 is used to drive the slanted push plate 33 to move along the third direction, so that the slanted push plate 33 abuts against the push plate 34 and moves towards the inner pull member 22 along the first direction, so that the push plate 34 pushes against the outer wall of the frame position of the corresponding inner pull mechanism 20.

[0060] In this embodiment, the end of the inclined push plate 33 away from the inclined push drive member 31 has a wedge-shaped surface 331, and the end of the push plate 34 away from the inner pull member 22 has an abutting surface 341. The abutting surface 341 abuts against and is adapted to the wedge-shaped surface 331. Thus, the wedge-shaped surface 331 and the abutting surface 341 provide a self-locking function during the pushing process, thereby pressing the push plate 34 tightly and preventing relative movement of the frame when subjected to locking torque, thus ensuring the accuracy of the frame.

[0061] In this embodiment, the end of the push plate 34 opposite to the inner pull member 22 is provided with a plurality of flexible blocks 342, such as silicone, so that the push plate 34 flexibly contacts the outer wall of the frame that is pushed against.

[0062] The inclined push mechanism 30 also includes a connecting block 35 and an elastic part 36.

[0063] The connecting block 35 is fixed to the upper surface of the support base 10 and connected to the fixing block 32. The connecting block 35 has a guide rail 351 extending along a first direction. A groove 343 is formed at the end of the push plate 34 away from the inner pull member 22. The guide rail 351 is disposed within the groove 343, allowing the push plate 34 to slide along the guide rail 351 in the first direction. An elastic part 36 is disposed within the groove 343, and both ends of the elastic part 36 abut against the guide rail 351 and the groove wall of the groove 343, respectively, allowing the push plate 34 to move elastically. In this embodiment, the elastic part 36 is a spring.

[0064] Please see Figure 5 The direct push mechanism 40 includes a direct push drive 41, a direct push plate 42, and a guide block 43.

[0065] A direct-push drive member 41 is disposed on the upper surface of the support base 10, and a guide block 43 is disposed on the upper surface of the support base 10. The guide block 43 has a guide groove 431 extending in a second direction. A direct-push plate 42 is slidably connected in the guide groove 431. One end of the direct-push plate 42 is connected to the direct-push drive member 41, and the other end of the direct-push plate 42 can extend into the support area 12 and be disposed opposite to the inner pull member 22 of the corresponding inner pull mechanism 20. The direct-push drive member 41 is used to drive the direct-push plate 42 to move in the guide groove 431 of the guide block 43 towards the inner pull member 22 in the second direction, so that the direct-push plate 42 pushes against the outer wall of the frame position pulled by the corresponding inner pull mechanism 20. In this way, the movement of the direct-push plate 42 is smooth, the force point is consistent, and the frame is subjected to uniform force. In this embodiment, the direct-push drive member 41 is a cylinder.

[0066] In this embodiment, a plurality of flexible blocks 342, such as silicone, are provided at one end of the push plate 42 opposite to the inner pull member 22, so that the push plate 42 can flexibly contact the outer wall of one side of the frame.

[0067] The following describes the implementation process of the shaping device 100 of this application, using a rectangle as an example:

[0068] First, place the frame on the bearing area 12 of the bearing seat 10. At this time, the long side of the frame is located between the holding part 221 of the inner pull member 22 and the push plate 34, and the short side of the frame is located between the holding part 221 of the inner pull member 22 and the straight push plate 42.

[0069] Next, the inner pull drive member 21 of one of the inner pull mechanisms 20 drives the inner pull member 22 to move away from the center of the frame along a first direction, so that the pulling part 221 of the inner pull member 22 pulls the inner sidewall of the frame and moves outward. The inner pull drive member 21 of the other inner pull mechanism 20 drives the inner pull member 22 to move away from the center of the frame along a second direction, so that the pulling part 221 of the inner pull member 22 pulls the inner sidewall of the frame and moves outward. The inclined push drive member 31 drives the inclined push plate 33 to move along a third direction, thereby inclined... The push plate 33 abuts against the push plate 34 and moves toward the inward pull member 22 in the first direction, so that the push plate 34 pushes against the outer wall of the corresponding inner pull mechanism 20 pull frame position. The direct push drive member 41 drives the direct push plate 42 to move in the guide groove 431 of the guide block 43 in the second direction, so that the direct push plate 42 pushes against the outer wall of the corresponding inner pull mechanism 20 pull frame position, thereby shaping the corresponding edge of the frame. There can be two or four edges until the straightness and parallelism of the corresponding edge of the frame meet the preset requirements.

[0070] The aforementioned shaping device 100 first pushes the oblique push mechanism 30 against the outer wall of the frame pulled by the corresponding inner pull mechanism 20; then the two inner pull mechanisms 20 respectively pull the inner side wall of the frame and move outward to tighten the frame; then the straight push mechanism 40 pushes against the outer wall of the frame position pulled by the corresponding inner pull mechanism 20, thereby shaping the corresponding side wall of the frame; this application performs micro-shaping of the corresponding side wall of the frame by pushing inward and pulling outward, which can make the dimensional accuracy of each side wall of the frame meet the requirements and the shaping accuracy is high.

[0071] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this application.

The inner pull drive component is disposed on the support base and is connected to the guide component. The inner pull component is elastically slidably disposed on the guide component through the elastic component. The inner pull drive component can drive the guide component to move so that the inner pull component pulls the inner sidewall of the frame and moves elastically outward. The structure of the inner pull component is similar to that of the inner sidewall of the frame. A second inclined pushing mechanism is located on the other side of the support base. The inclined pushing mechanism includes an inclined pushing drive component, a fixed block, an inclined pushing plate, and a pushing plate. The fixed block is located on the support base, the inclined pushing drive component is located on the fixed block, the inclined pushing plate is slidably disposed within the fixed block, one end of the inclined pushing plate is connected to the inclined pushing drive component, and the end of the inclined pushing plate away from the inclined pushing drive component has a wedge-shaped surface. The pushing plate is slidably disposed within the fixed block, and the sliding directions of the pushing plate and the inclined pushing plate are different. The end of the moving plate away from the inner pull member has an abutting surface, which abuts and fits with the wedge-shaped surface. The other end of the pushing plate is disposed opposite to the inner pull member of the corresponding inner pull mechanism. The inclined push drive member is used to drive the inclined push plate to move, so that the inclined push plate abuts against the pushing plate and moves toward the inner pull member, so that the pushing plate pushes against the outer wall of the corresponding inner pull mechanism's pull frame position. The wedge-shaped surface and the abutting surface have a self-locking function during the pushing process, which can press the pushing plate tightly. Two direct push mechanisms are provided on the support base and adjacent to the oblique push mechanism. The direct push mechanisms are used to push against the other two opposite outer walls of the frame to shape the frame.

9. The shaping apparatus as claimed in claim 8, wherein, The inclined push mechanism includes an inclined push plate and a push plate. The push plate is slidably disposed on the support seat. One end of the push plate abuts against the inclined push plate, and the other end of the push plate is disposed opposite to the corresponding inner pull mechanism. When the inclined push plate is driven to move, the inclined push plate abuts against the push plate and moves toward the inner pull mechanism, so that the push plate pushes against the outer wall of the corresponding frame position.

10. The shaping apparatus as claimed in claim 9, wherein, The push mechanism includes a push plate, which pushes against the outer wall of the frame when it moves toward the pull mechanism.
