Description

Technical Field

[0001] This application relates to the field of flip cover welding technology, and in particular to a welding fixture for processing metal flip covers. Background Technology

[0002] A flip cover typically includes a first flat section, a bent section disposed on the first flat section, a second flat section disposed on the bent section, and a third flat section connecting the first flat section, the bent section, and the second flat section. It is mounted on the side of a semiconductor device and provides physical protection and structural reinforcement for the semiconductor device.

[0003] In related technologies, the various components of the flip cover need to be initially connected by electric welding before being placed on a welding fixture for further welding. Currently, the industry generally uses a four-point clamping welding fixture, which has a simple structure and low cost.

[0004] The existing flip-top welding process has the following problems: the four-point welding fixture cannot completely fix the flip-top during welding, which causes slight changes in the welding angle of the flip-top, resulting in uneven heating and deformation, thus reducing the product quality of the flip-top. Summary of the Invention

[0005] To improve the product quality of flip covers, this application provides a welding fixture for processing metal flip covers.

[0006] The welding fixture for processing metal flip covers provided in this application adopts the following technical solution: A welding fixture for processing metal flip covers includes: a base and a support assembly. The support assembly includes a bending support frame disposed on the base, a first vertical support plate disposed on the bending support frame, and a second vertical support plate connecting the base, the bending support frame, and the first vertical support plate. The base, the bending support frame, the first vertical support plate, and the second vertical support plate respectively abut against a first straight portion, a bent portion, a second straight portion, and a third straight portion of the flip cover.

[0007] By adopting the above scheme, contact constraints on the flip cover in three-dimensional space are achieved, effectively reducing the offset during flip cover welding, thereby reducing uneven deformation caused by changes in welding angle and improving the welding quality of the flip cover.

[0008] Preferably, the base, the bent support frame, and the first vertical support plate form a triangular structure.

[0009] By adopting the above scheme, the support capacity of the bend in the flip cover is improved by utilizing geometric stability, reducing the load on the bend as a stress concentration area, thereby reducing the risk of breakage of a single component.

[0010] Preferably, it also includes a clamping assembly, which includes a pressure clamp and a push clamp, the pressure clamp and the push clamp being arranged circumferentially along the outer contour of the flip cover on the welding fixture.

[0011] By adopting the above scheme, the clamp presses down vertically on the flip cover plane to reduce warping, and the push clamp presses horizontally against the flip cover sidewall to reduce offset. The clamp and push clamp work together to achieve dynamic stability of the flip cover welding process by being distributed circumferentially along the outer contour of the flip cover.

[0012] Preferably, the pressure clamps and push clamps distributed on the base are staggered and spaced apart.

[0013] By adopting the above scheme, vertical pressure and horizontal preload form a continuous support belt, which effectively absorbs welding vibration and balances the stress on the first straight part of the flip cover through multi-directional constraints.

[0014] Preferably, the support assembly further includes a plurality of positioning brackets, which are disposed on the base and adapted to the size of the first flat portion of the flip cover.

[0015] By adopting the above solution, it plays a guiding role when the operator places the flip cover, improving processing efficiency. The flip cover transmits vertical pressure to the base through the positioning bracket, reducing wear caused by direct force on the base.

[0016] Preferably, the side of the second vertical support plate away from the flip cover is provided with a plurality of reinforcing ribs, one end of which is connected to the second vertical support plate and the other end is connected to the base.

[0017] By adopting the above scheme, the mechanical transmission path of vibration load from the second vertical support plate to the base is optimized, thereby improving the bending strength of the second vertical support plate.

[0018] Preferably, a plurality of square tubes are provided below the base, and the plurality of square tubes are arranged at intervals and fixedly connected to the lower surface of the base.

[0019] By adopting the above scheme, a grid support system is formed, which transforms concentrated loads into uniformly distributed loads that are transmitted downwards, thereby reducing the peak stress of the base and minimizing the occurrence of local settlement.

[0020] Preferably, all right-angle connection points of the base are rounded.

[0021] By adopting the above solution, the risk of scratches to operators during welding can be reduced.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Achieve contact constraints on the flip cover in three-dimensional space, effectively reduce the offset during flip cover welding, thereby reducing uneven deformation caused by changes in welding angle and improving the welding quality of the flip cover; 2. Improved the load-bearing capacity and dynamic stability of the device; 3. Reduce wear and tear on the device and the occurrence of workers being scratched. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a welding fixture for processing metal flip covers. (Refer to...) Figure 1-3 A welding fixture for processing metal flip covers includes a base 1 and a support assembly 2. The base 1 has a plurality of waist-shaped holes 13. The support assembly 2 includes a bent support frame 21 installed on the base 1, a first vertical support plate 23 integrally formed with the bent support frame 21, and a second vertical support plate 24 connecting the base 1, the bent support frame 21 and the first vertical support plate 23.

[0031] Furthermore, when the flip cover 4 is placed in the welding station, the base 1, the bending support frame 21, the first vertical support plate 23 and the second vertical support plate 24 respectively abut against the first straight part 41, the bending part 42, the second straight part 43 and the third straight part 44 of the flip cover 4.

[0032] Correspondingly, the base 1 is tightly fitted with the first straight part 41 of the flip cover 4, the bent support plate is tightly fitted with the bent part 42, the first vertical support plate 23 is tightly fitted with the second straight part 43, and the second vertical support plate 24 is tightly fitted with the third straight part 44. This device achieves full contact and fixation of the flip cover 4 through multi-structure collaboration. While reducing the displacement of the flip cover 4 during welding, it also reduces thermal stress deformation by diverting welding heat, effectively improving the welding quality of the flip cover 4.

[0033] Specifically, the base 1, the bent support frame 21, and the first vertical support plate 23 form a triangular structure, which realizes a stable mechanical transmission path and reduces the occurrence of local collapse or warping caused by welding thermal deformation.

[0034] Furthermore, the bending support frame 21, acting as an inclined side, decomposes the load of the flip cover 4 into the vertical pressure of the base 1 and the horizontal component of the first vertical support plate 23, reducing the risk of breakage of a single component.

[0035] In the process described above, the base 1 is a flat plate-like structure. The right-angle connection points of the base 1 are all rounded to ensure that the stress at the corners of the base 1 is evenly distributed. At the same time, it reduces the possibility of operators being scratched by the edges of the base 1 when welding the flip cover 4.

[0036] Furthermore, in this embodiment, three square tubes 11 are fixedly connected below the base 1. The three square tubes 11 are spaced apart in the width direction of the base 1 and extend laterally to form a grid support system, which converts the total load of the base 1 into a uniformly distributed load and transmits it downward, thereby reducing the stress peak of the base 1 and reducing the risk of local settlement.

[0037] On the other hand, refer to Figure 3-5 It also includes a clamping assembly 3, which includes a pressure clamp 32 and a push clamp 31. In this embodiment, a total of five push clamps 31 and six pressure clamps 32 are provided. The pressure clamps 32 and push clamps 31 are installed circumferentially on the base 1, the first vertical support plate 23 and the second vertical support plate 24 along the outer contour of the flip cover 4. This can decompose the welding stress into multiple directional vectors and reduce the risk of single-point overload.

[0038] Furthermore, the clamps 32 and 31 installed on the base 1 are staggered and spaced apart. Therefore, the vertical pressure applied to the flip cover 4 by the clamps 32 and the horizontal pre-tightening force provided by the 31 form a continuous support band. The staggered clamping layout achieves mechanical complementarity, completing the high-precision horizontal domain constraint of the flip cover 4, effectively absorbing welding vibration and balancing the stress on the first straight part 41 of the flip cover 4.

[0039] Specifically, in this embodiment, the push clamp 31 includes a first pad 311 mounted on the base 1, a slide bar 313 arranged parallel to the first pad 311 via a first connector 312, and a slider 314 slidably disposed on the slide bar 313. The push clamp 31 provides a horizontal preload to the side wall of the flip cover 4 by sliding the slider 314 on the slide bar 313.

[0040] Furthermore, in this embodiment, the clamp 32 includes a second pad 321 mounted on the base 1 and on the first vertical support plate 23 or the second vertical support plate 24, a hollow connecting plate 323 arranged parallel to the second pad 321 via a second connector 322, and a fastening bolt 324 that passes through the hollow connecting plate 323. Both ends of the fastening bolt 324 are fixed to the hollow connecting plate 323 by nuts 325. The bottom of the fastening bolt 324 is also provided with a nut 325 for abutting against the surface of the flip cover 4. The clamp 32 lowers down until it abuts against the surface of the flip cover 4 by rotating the lowest nut 325, and provides vertical pressure to the side wall of the flip cover 4.

[0041] In summary, the clamp 32 presses down vertically on the plane of the flip cover 4 to reduce warping, and the push clamp 31 presses horizontally against the side wall of the flip cover 4 to reduce offset. The clamp 32 and the push clamp 31 are distributed circumferentially along the outer contour of the flip cover 4, automatically compensating for the tolerance of the flip cover 4, improving the positioning accuracy of different batches of flip covers 4, and working together to achieve dynamic stability of the welding process of the flip cover 4.

[0042] On the other hand, the support component 2 also includes several positioning brackets 22. In this embodiment, a total of four positioning brackets 22 are provided. The four positioning brackets 22 are installed on the base 1 and extend along the width direction of the base 1. The size of the positioning brackets 22 is adapted to the size of the first flat part 41 of the flip cover 4.

[0043] Therefore, the top plane of the positioning bracket 22 forms a surface contact with the bottom of the first flat part 41 of the flip cover 4, establishing a stable assembly reference and reducing the risk of tilting when the flip cover 4 is initially placed.

[0044] Furthermore, the positioning bracket 22 plays a guiding role when the flip cover 4 is placed. Through precise contour matching, the operator can pre-place the flip cover 4 without fine adjustment, thereby reducing assembly time. At the same time, the positioning bracket 22 can vertically transmit the clamping pressure to the base 1, reducing the occurrence of direct pressure deformation of the thin-walled area of ​​the flip cover 4 and local wear of the base 1.

[0045] In addition, in this embodiment, five reinforcing ribs 25 are provided at intervals on the side of the second vertical support plate 24 away from the flip cover 4. All five reinforcing ribs 25 are arranged in a right-angled trapezoidal structure. One right-angled side of the reinforcing rib 25 is fixedly connected to the second vertical support plate 24, and the other right-angled side is fixedly connected to the base 1.

[0046] Correspondingly, the reinforcing rib 25 connects the second vertical support plate 24 and the base 1 with an oblique edge, converting the welding vibration load into stress components and transmitting them to the base 1, thereby reducing stress concentration at the bottom of the second vertical support and dispersing and absorbing vibration potential energy, and improving the bending stiffness of the device.

[0047] The implementation principle of a welding fixture for processing metal flip covers in this application embodiment is as follows: the device is closely fitted with each component of the flip cover 4 through the base 1, bending support frame 21, first vertical support plate 23 and second vertical support plate 24, and with the clamping components 3 distributed circumferentially along the outer contour of the flip cover 4, the flip cover 4 is fully contacted and fixed in three-dimensional space, which effectively reduces the offset of the flip cover 4 during welding, thereby reducing the uneven deformation caused by the change of welding angle and improving the welding quality of the flip cover 4.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
