Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a wedge anti-rotation fixing mechanism. Background Technology

[0002] In the existing mobile phone product manufacturing process, refer to the appendix to this application specification. Figure 1 and appendix Figure 2 As shown, multiple flat spring clips 2000 are typically fixed at multiple preset positions on the bottom surface of the phone back cover 3000. Then, a decorative panel with the same outer circumference size, such as a glass back panel, is attached to the bottom surface of the corresponding phone back cover 3000 to seal and cover the attached flat spring clips 2000. The attached flat spring clips 2000 mainly serve to fix the decorative panel, and they are basically installed and fixed by fastening bolts 40.

[0003] In traditional fixing processes, screw holes are typically made at multiple preset positions on the bottom surface of the phone back cover 3000, and fixing holes are made on multiple flat spring pieces 2000, with the fixing holes and screw holes aligned one by one. Then, fastening bolts 40 are screwed into the fixing holes and screw holes at multiple relative positions to fix the phone back cover 3000 and the multiple flat spring pieces 2000 together.

[0004] However, there are certain requirements for fixing multiple flat spring clips 2000. They need to be fixed in a preset position. In actual operation, when tightening the fastening bolts 40 to the corresponding fixing holes and screw holes, the flat spring clips 2000 to be fixed will rotate slightly. As a result, when they are finally locked, they cannot be accurately fixed in the preset position. This requires subsequent fine-tuning of their fixing position, which is not only time-consuming and labor-intensive, but also increases labor costs and greatly extends the product assembly and production cycle.

[0005] In response, the inventor of this patent, drawing on practical work experience, reflected on the problems encountered in his work, reviewed a large amount of scientific research data and literature, and conducted a novelty search, gradually conceived and designed this application to solve the relevant technical problems. Summary of the Invention

[0006] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a wedge anti-rotation fixing mechanism.

[0007] To achieve the above objectives, according to an embodiment of the present invention, a wedge anti-rotation fixing mechanism is used to attach and fix a flat spring sheet to a preset position on the bottom surface of the back cover of a mobile phone. The flat spring sheet has fixing holes penetrating its upper and lower end faces. The mechanism includes a workpiece bearing plate, a workpiece pressure plate, and a liftable wedge.

[0008] The workpiece pressure plate is stacked on the workpiece support plate to press and fix the mobile phone back cover;

[0009] The upper surface of the workpiece support plate is provided with a resting position for placing the flat spring sheet; the resting position has a screw hole extending through to the bottom surface of the workpiece support plate; when the flat spring sheet is placed in the resting position, the fixing hole on it is directly opposite the screw hole; the workpiece support plate also has a lifting port extending through its upper and lower surfaces next to the resting position; the liftable wedge is installed in the lifting port, its upper part is located above the first long side of the flat spring sheet, and has a bearing surface directly opposite the first long side of the flat spring sheet;

[0010] When the liftable wedge is lowered by a preset stroke along the lifting port, the abutting surface moves toward the direction of the first long side of the flat spring to abut against the first long side of the flat spring.

[0011] In addition, the wedge anti-rotation fixing mechanism according to the above embodiments of the present invention may also have the following additional technical features:

[0012] According to one embodiment of the present invention, the liftable inclined wedge includes a Z-shaped lifting block and a return spring;

[0013] The Z-shaped lifting block includes an inclined wedge, a horizontally fixed upper push block at the upper end of the inclined wedge, and a horizontally fixed lower fixing block opposite to the upper push block at the lower end of the inclined wedge; the lifting port is also formed into a Z-shaped structure, including an upper support groove for supporting the upper push block, an inclined slide for locking the inclined wedge, and a lower locking groove for locking the lower fixing block.

[0014] The upper push block has a vertically abutting surface at its end; the reset spring is vertically fixed to the upper end face of the lower fixed block, and its top is fixed to the upper top surface of the lower slot.

[0015] The upper end of the inclined slide is away from the resting position, and the lower end is inclined directly below the resting position.

[0016] According to one embodiment of the present invention, the upper surface of the workpiece bearing plate is further provided with an anti-rotation positioning piece next to the fixing hole for pressing against the first end of the flat spring sheet from the first end.

[0017] According to one embodiment of the present invention, the upper end face of the workpiece carrier plate is formed into a workpiece bearing surface at the middle; the upper end face of the workpiece carrier plate is provided with a plurality of clamps around the workpiece bearing surface for clamping the back cover of the mobile phone.

[0018] According to one embodiment of the present invention, the periphery of the workpiece pressure plate and the periphery of the workpiece support plate are detachably fixed, and a top clamping plate for pressing and fixing the periphery of the mobile phone back cover is provided at the center of the bottom surface of the workpiece pressure plate; the outer periphery of the top clamping plate is adapted to the outer periphery of the mobile phone back cover.

[0019] According to one embodiment of the present invention, the bottom surface of the top plate is provided with a plurality of elastic pressure-relieving members that correspond to a plurality of pressure-fixing positions on the bottom surface of the inner side of the back cover of the mobile phone.

[0020] According to one embodiment of the present invention, each of the elastic pressure-relieving members includes a pressure-fixing post and a pressure-relieving spring connected upward to the top of the pressure-fixing post;

[0021] The bottom surface of the top plate has multiple guide grooves facing upwards, which correspond to multiple pressing positions of the back cover of the mobile phone; the upper ends of multiple pressure-relieving springs are fixedly mounted on the top of the multiple guide grooves; the upper parts of multiple pressure-fixing columns are correspondingly limited within the multiple guide grooves.

[0022] According to one embodiment of the present invention, a plurality of inverted L-shaped fixing buckles are uniformly protruding upwards from the periphery of the upper surface of the workpiece bearing plate;

[0023] The workpiece pressure plate is also uniformly provided with a plurality of elastic fasteners; the positions of the plurality of elastic fasteners are directly opposite the plurality of inverted L-shaped fixing buckles, so that when the plurality of inverted L-shaped fixing buckles are inserted into them from bottom to top with an interference fit, the plurality of inverted L-shaped fixing buckles are locked.

[0024] According to one embodiment of the present invention, each of the resilient fasteners includes a movable plate and a telescopic spring;

[0025] The workpiece pressure plate has horizontally openable grooves around its periphery, and bottom openings extending through to the bottom surface of the workpiece pressure plate are partially opened in the bottom of each of the multiple openable grooves; multiple movable plates are correspondingly and movably fitted into the multiple openable grooves, and multiple telescopic springs are correspondingly connected between the inner walls of the multiple openable grooves and the inner sides of the multiple movable plates; each movable plate has a locking slot extending through its upper and lower end faces; the multiple locking slots are correspondingly offset from the multiple bottom openings;

[0026] When multiple movable plates are pressed in the direction of the multiple telescopic springs so that the multiple lock holes are aligned with the multiple bottom openings, the upper ends of the multiple inverted L-shaped fixing buckles can pass through the multiple lock holes from bottom to top in an interference fit.

[0027] When the multiple movable plates are released to allow the multiple telescopic springs to elastically return to their original position, the multiple locking ports are repositioned to the multiple bottom openings, and the upper ends of the multiple inverted L-shaped fixing buckles are locked and fixed by the multiple locking ports.

[0028] According to one embodiment of the present invention, each of the inverted L-shaped fixing buckles includes a vertically arranged connecting portion and a fixing portion horizontally connected to the upper end of the connecting portion; the upper surfaces of the plurality of fixing portions are respectively cut from the upper part of their connecting end to the lower part of their end to form a snap-in pushing surface.

[0029] The beneficial effects of this invention are:

[0030] The anti-rotation fixing mechanism for the wedge provided in this application first raises the liftable wedge to its highest position and places the flat spring in the placement position so that the fixing hole is aligned with the screw hole. Then, the back cover of the mobile phone is placed on the workpiece support plate and pressed and fixed by the workpiece pressure plate. At this time, the fixing hole is aligned with and tightly against the screw hole. Subsequently, the liftable wedge is lowered along the lifting port by a preset stroke. At this time, the abutting surface moves in the direction of the first long side of the flat spring to abut against the first long side of the flat spring. Subsequently, from bottom to top, the required fastening bolts are screwed into the fixing hole and the corresponding screw hole through the screw hole to lock and fix the flat spring to the bottom surface of the phone back cover. During this operation, the abutting surface will always press against the first long side of the flat spring, making it difficult for the flat spring to rotate during the fixing process. Its anti-rotation effect is good, so it can be accurately fixed in the preset position. This eliminates the need for subsequent fine-tuning of its fixing position, which not only saves time and effort and reduces labor costs, but also greatly shortens the product assembly and production cycle.

[0031] Furthermore, by setting up this application, it is ensured that it is highly practical and effective in use, thus possessing significant market promotion value and becoming very popular. This application is also expected to achieve effective popularization.

[0092] The following describes in detail, with reference to the accompanying drawings, the wedge anti-rotation fixing mechanism 1000 of the present invention.

[0093] Reference Figures 1 to 11 As shown, the wedge anti-rotation fixing mechanism 1000 provided according to an embodiment of the present invention is used to fix the flat spring sheet 2000 to a preset position on the bottom surface of the mobile phone back cover 3000. A screw hole 60 is opened upwards at the preset position. A fixing hole 50 penetrating the upper and lower end faces of the flat spring sheet 2000 is opened on the flat spring sheet 2000. The fixing hole 50 and the screw hole 60 are positioned opposite each other. Specifically, refer to... Figure 4 , Figure 5 and Figure 7 As shown; based on this, this application includes a workpiece support plate 10, a workpiece pressure plate 20, and a liftable inclined wedge 30;

[0094] The workpiece pressure plate 20 is stacked on the workpiece support plate 10 to press and fix the mobile phone back cover 3000 and each other.

[0095] Furthermore, in comparison Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the upper surface of the workpiece support plate 10 is provided with a resting position 101 for resting the flat spring sheet 2000; the resting position 101 has a screw hole 102 extending through to the bottom surface of the workpiece support plate 10; when the flat spring sheet 2000 is placed on the resting position 101, the fixing hole 50 on it is directly opposite the screw hole 102; the workpiece support plate 10 also has a lifting port 103 extending through its upper and lower surfaces on the side of the resting position 101; the liftable inclined wedge 30 is installed in the lifting port 103, its upper part is located above the first long side of the flat spring sheet 2000, and has a bearing surface 30a directly opposite the first long side of the flat spring sheet 2000.

[0096] When the liftable wedge 30 is lowered by a preset stroke along the lifting port 103, the abutment surface 30a moves toward the direction of the first long side of the flat spring 2000 to abut against the first long side of the flat spring 2000.

[0097] Based on the above, it is clear that in specific implementation, this application is mainly used as the anti-rotation fixing mechanism 1000 for the wedge.

[0098] Specifically, when applying this application, first, the liftable wedge 30 is raised to its highest position, and the flat spring 2000 is placed in the placement position 101 so that the fixing hole 50 is aligned with the screw hole 102. Then, the mobile phone back cover 3000 is placed on the workpiece support plate 10 and pressed and fixed by the workpiece pressure plate 20. At this time, the fixing hole 50 will be aligned with and tightly against the screw hole 60. Subsequently, the liftable wedge 30 is lowered along the lifting port 103 by a preset stroke. At this time, the abutment surface 30a will move in the direction of the first long side of the flat spring 2000 to abut against the flat spring 2000. 00. Following the first long side, from bottom to top, the required fastening bolts 40 are screwed into the fixing hole 50 and the corresponding screw hole 60 through the screw hole 102 to lock and fix the flat spring piece 2000 to the bottom surface of the phone back cover 3000. During this operation, the abutment surface 30a will always press against the first long side of the flat spring piece 2000, making it difficult for the flat spring piece 2000 to rotate during the fixing process. Its anti-rotation effect is good, so it can be accurately fixed in the preset position. This eliminates the need for subsequent fine-tuning of its fixing position, which not only saves time and effort and reduces labor costs, but also greatly shortens the product assembly and production cycle.

[0099] Specifically, the product illustration shows a flat spring piece 2000 fixedly attached to a preset position on the bottom surface of the phone back cover 3000 by fastening bolts 40. Please refer to the attached drawings in this application specification. Figure 1 and Figure 2 As shown.

[0100] Furthermore, by setting up this application, it becomes highly practical and effective.

[0101] Furthermore, in specific implementation, in accordance with... Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the liftable inclined wedge 30 includes a Z-shaped lifting block 301 and a return spring 302;

[0102] The Z-shaped lifting block 301 includes an inclined wedge block 3011, an upper push block 3012 horizontally fixed at the upper end of the inclined wedge block 3011, and a lower fixing block 3013 horizontally fixed at the lower end of the inclined wedge block 3011 opposite to the upper push block 3012. The lifting port 103 is also formed into a Z-shaped structure, including an upper support groove 1031 for supporting the upper push block 3012, an inclined slide 1032 for interference fit to engage the inclined wedge block 3011, and a lower slot 1033 for engaging the lower fixing block 3013.

[0103] Furthermore, the upper push block 3012 has a vertically provided abutment surface 30a at its end; the reset spring 302 is vertically fixed to the upper end face of the lower fixing block 3013, and its top is fixed to the upper top surface of the lower slot 1033.

[0104] Meanwhile, the upper end of the inclined slide 1032 is away from the resting position 101, and the lower end is inclined downwards towards the resting position 101.

[0105] When the inclined wedge block 3011 is lowered along the inclined slide 1032 by a predetermined stroke, the abutting surface 30a moves toward the direction of the first long side of the flat spring piece 2000 to abut against the first long side of the flat spring piece 2000.

[0106] From the above, we can conclude that:

[0107] Firstly, the liftable inclined wedge 30 described in this application includes a Z-shaped lifting block 301 and a return spring 302; the Z-shaped lifting block 301 is interference-fitted into the lifting port 103 of the Z-shaped structure, which makes it have good anti-fall-off performance in the vertical direction, making it stable and reliable in use.

[0108] Secondly, initially, when the application is pushed upwards, the inclined wedge block 3011 will rise along the inclined slide 1032 by a predetermined stroke. At this time, the supporting surface 30a will move away from the resting position 101, so that the flat spring piece 2000 can be placed in the resting position 101. After the mobile phone back cover 3000 is pressed and fixed between the workpiece bearing plate 10 and the workpiece pressure plate 20, the application can be released. At this time, the return spring 302 will elastically return to its original position and push downwards against the lower fixing block 3013, so that the inclined wedge block 3011 can be driven to descend along the inclined slide 1032 by a predetermined stroke, so that the supporting surface 30a faces the direction of the first long side of the flat spring piece 2000. During the movement, after the inclined wedge block 3011 described in this application descends a preset distance along the inclined slide 1032, the abutment surface 30a will press against the first long side of the flat spring piece 2000. Thus, even if the fastening bolt 40 is subsequently screwed into the fixing hole 50 and the screw hole 60 opposite it through the screw hole 102 from bottom to top to lock the flat spring piece 2000 to the bottom surface of the phone back cover 3000, the abutment surface 30a will always press against the first long side of the flat spring piece 2000 during this operation, making it difficult for the flat spring piece 2000 to rotate during the fixing process. Its anti-rotation effect is good, so that it can be accurately fixed in the preset position.

[0109] As described above, it can be said that the structural design of the liftable inclined wedge 30 described in this application is very ingenious. When it moves obliquely in the vertical direction, its movement is stable and reliable and it is not easy to fall off.

[0110] Furthermore, in the specific implementation, we will continue to refer to... Figure 8 and Figure 9 As shown, according to an embodiment of the present invention, the upper end surface of the workpiece bearing plate 10 is further provided with an anti-rotation positioning piece 104 for pressing against the first end of the flat spring 2000 from the side of the fixing hole 50.

[0111] Therefore, in actual use of this application to fix the flat spring 2000 to the bottom surface of the mobile phone back cover 3000, by setting the anti-rotation positioning piece 104 for secondary anti-rotation positioning, the fastening bolt 40 to be used is screwed into the fixing hole 50 and the screw hole 60 directly opposite it through the screw hole 102 from bottom to top, so as to lock and fix the flat spring 2000 to the bottom surface of the mobile phone back cover 3000. The abutting surface 30a is always pressed against the first long side of the flat spring 2000, and when the anti-rotation positioning piece 104 presses against the first end of the flat spring 2000 from the first end, the flat spring 2000 is less likely to rotate during the fixing process, and its anti-rotation effect can be better.

[0112] Furthermore, in specific implementation, in accordance with... Figure 4 and Figure 8 As shown, according to an embodiment of the present invention, the upper end face of the workpiece support plate 10 is formed into a workpiece support surface 105 in the middle; the upper end face of the workpiece support plate 10 is provided with a plurality of clamps 106 for clamping the mobile phone back cover 3000 around the workpiece support surface 105.

[0113] Therefore, in actual use of this application, when the mobile phone back cover 3000 is placed from top to bottom on the workpiece bearing surface 105, its outer periphery can be clamped and fixed by the multiple grippers 106, so that it will not shift circumferentially.

[0114] Furthermore, in specific implementation, refer to the diagram. Figure 7 and Figure 11 As shown, according to an embodiment of the present invention, the periphery of the workpiece pressure plate 20 is detachably fixed to the periphery of the workpiece support plate 10, and a top clamping plate 201 for pressing and fixing the periphery of the mobile phone back cover 3000 is provided at the center of the lower bottom surface of the workpiece pressure plate 20; the outer periphery of the top clamping plate 201 is adapted to the outer periphery of the mobile phone back cover 3000.

[0115] Therefore, it is clear that when the workpiece pressure plate 20 is stacked and fixed on the workpiece support plate 10, the outer periphery of the top clamping plate 201 provided on its bottom surface will press against the upper periphery of the mobile phone back cover 3000, so that the mobile phone back cover 3000 is indeed well fixed and will not shift in the vertical direction.

[0116] Secondly, in specific implementation, refer to Figure 7 , Figure 10 and Figure 11 As shown, according to an embodiment of the present invention, the bottom surface of the top plate 201 is provided with a plurality of elastic pressure relief members 202 that correspond to and are directly opposite to a plurality of pressure-fixing positions on the inner bottom surface of the mobile phone back cover 3000.

[0117] Therefore, when the workpiece pressure plate 20 presses down to fix the mobile phone back cover 3000, the multiple elastic pressure buffers 202 buffer the downward pressure, making it less likely for the multiple pressing positions of the mobile phone back cover 3000 to be crushed or cracked, thus making the application highly reliable.

[0118] Preferably, in this technical solution, according to an embodiment of the present invention, each of the elastic pressure-relieving members 202 includes a pressure-fixing post 2021 and a pressure-relieving spring 2022 connected upward to the top of the pressure-fixing post 2021;

[0119] The top plate 201 has multiple guide grooves 2011 on its bottom surface facing upwards, which correspond to multiple pressing positions of the back cover 3000 of the mobile phone; the upper ends of multiple pressure-relieving springs 2022 are fixedly mounted on the top of the multiple guide grooves 2011; the upper parts of multiple pressure-fixing columns 2021 are correspondingly limited within the multiple guide grooves 2011.

[0120] In conclusion, based on the above:

[0121] On the one hand, when each of the elastic pressure-relieving components 202 includes a pressure-fixing post 2021 and a pressure-relieving spring 2022 connected upward to the top of the pressure-fixing post 2021, the multiple pressure-relieving springs 2022 provide pressure relief in the vertical direction, making it difficult for the multiple pressure-fixing posts 2021 to crush or crack the multiple pressure-fixing positions of the mobile phone back cover 3000 in the vertical direction.

[0122] On the other hand, since the upper ends of the multiple pressure-relieving springs 2022 are fixedly mounted on the top of the multiple guide grooves 2011, and in the initial state, the upper parts of the multiple pressure-fixing columns 2021 are correspondingly limited within the multiple guide grooves 2011 by interference fit, the multiple guide grooves 2011 not only serve to limit and fix the multiple pressure-relieving springs 2022 so that the multiple pressure-relieving springs 2022 can only extend and retract in the vertical direction, but also guide the multiple pressure-fixing columns 2021 in the vertical direction so that they are not easily displaced circumferentially.

[0123] Furthermore, through the above-mentioned optimized design, all of the elastic pressure-relieving components 202 described in this application are stable and reliable in use.

[0124] Furthermore, in specific implementation, in accordance with Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown,

[0125] According to one embodiment of the present invention, the upper end face of the workpiece bearing plate 10 is provided with a plurality of five inverted L-shaped fixing buckles 107 that are evenly protruding upwards from the periphery;

[0126] Based on this, in this application, the workpiece pressure plate 20 is also uniformly provided with a plurality of elastic fasteners 203 around its periphery; the positions of the plurality of elastic fasteners 203 are directly opposite to the plurality of inverted L-shaped fixing buckles 107, so that when the plurality of inverted L-shaped fixing buckles 107 are inserted into them from bottom to top with an interference fit, the plurality of inverted L-shaped fixing buckles 107 are locked.

[0127] Therefore, this application sets multiple elastic fasteners 203 to correspondingly lock multiple inverted L-shaped fixing buckles 107, so that the workpiece pressure plate 20 can be fixed as one with the workpiece bearing plate 10, so as to achieve long-term pressing and fixing of the mobile phone back cover 3000.

[0128] Preferably, in this technical solution, according to an embodiment of the present invention, each of the elastic cards

[0129] Firmware 203 includes a movable plate 2031 and a telescopic spring 2032;

[0130] 5. Among them, the workpiece pressure plate 20 has horizontally opened movable grooves 204 on its periphery, and in multiple of the above...

[0131] Each movable groove 204 has a bottom opening 205 extending through to the bottom surface of the workpiece pressure plate 20; multiple movable plates 2031 are correspondingly and movably fitted into multiple movable grooves 204; multiple telescopic springs 2032 are correspondingly connected to the inner walls of multiple movable grooves 204 and the multiple movable plates 2031.

[0132] Between the sides; each of the movable plates 2031 has a locking slot 20311 that penetrates its upper and lower ends; the multiple locking slots 20311 are staggered with the multiple bottom openings 205;

[0133] Regarding the above, it should be noted that the locking principle of the multiple elastic fasteners 203 corresponding to the multiple inverted L-shaped fixing buckles 107 in this application is roughly as follows:

[0134] When the multiple telescopic springs 2032 are located, the multiple movable plates 2031 are pressed accordingly.

[0135] When the multiple locking slots 20311 are aligned with the multiple bottom openings 205 and the workpiece pressure plate 5 20 is placed on the workpiece support plate 10 from top to bottom, the upper ends of the multiple inverted L-shaped fixing buckles 107 will pass through the multiple locking slots 20311 from bottom to top with an interference fit. Subsequently, when the multiple movable plates 2031 are released to allow the multiple telescopic springs 2032 to elastically return to their original positions, the multiple locking slots 20311 will be repositioned to the multiple bottom openings 205. At this time, the upper ends of the multiple inverted L-shaped fixing buckles 107 will be locked and fixed by the multiple locking slots 20311.

[0136] Conversely, when multiple movable plates 2031 are pressed again in the direction of multiple telescopic springs 2032 so that multiple locking slots 20311 are aligned with multiple bottom openings 205, the workpiece pressure plate 20 of this application can be removed from bottom to top. At this time, the upper ends of multiple inverted L-shaped fixing buckles 107 will be opposite to multiple sets of locking slots 20311 and bottom openings 205, so as to remove the mobile phone back cover 3000 with the flat spring sheet 2000 fixed on the bottom surface.

[0137] Preferably, in this technical solution, according to an embodiment of the present invention, each of the inverted L-shaped fixing buckles 107 includes a vertically arranged connecting portion 1071 and a fixing portion 1072 horizontally connected to the upper end of the connecting portion 1071; the upper surfaces of the plurality of fixing portions 1072 are cut from the upper part of their connecting end to the lower part of their end to form a snap-in pushing surface 10721.

[0138] Therefore, by setting multiple snap-fit ​​pushing surfaces 10721, when the workpiece pressure plate 20 is placed on the workpiece support plate 10 from top to bottom, it is not necessary to press multiple movable plates 2031 in the direction of multiple telescopic springs 2032. Instead, the multiple snap-fit ​​pushing surfaces 10721 are used for pushing, allowing the multiple movable plates 2031 to automatically move a preset distance in the direction of multiple telescopic springs 2032. During the travel, if the multiple locking slots 20311 are aligned with the multiple bottom openings 205, then the fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 will automatically pass through the multiple locking slots 20311. After that, in an instant, the multiple telescopic springs 2032 will elastically reset, so that the multiple locking slots 20311 will be repositioned to the multiple bottom openings 205. At this time, the fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 will be locked and fixed by the multiple locking slots 20311.

[0139] Furthermore, through the above-mentioned optimized design, even when the workpiece pressure plate 20 is placed on the workpiece support plate 10 from top to bottom during the use of this application, it is not necessary to manually operate the multiple movable plates 2031. The fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 are locked and fixed by the multiple locking holes 20311, so that the workpiece pressure plate 20 and the workpiece support plate 10 are fixed as one unit, so as to finally achieve long-term pressing and fixing of the mobile phone back shell 3000 to fix the flat spring piece 2000 to its bottom surface.

[0140] At the same time, in specific implementation, in accordance with Figure 10 and Figure 11As shown, according to one embodiment of the present invention, the lower bottom surfaces of the plurality of movable plates 2031 are cut along the upper edge of the plurality of locking slots 20311 on the side of the plurality of locking slots 20311 respectively to form a snap-in guide surface 20312; the plurality of snap-in guide surfaces 20312 are parallel to the plurality of snap-in pushing surfaces 10721 and are located directly above the plurality of snap-in pushing surfaces 10721 respectively;

[0141] Therefore, it can be understood that in the specific implementation of this application, when the workpiece pressure plate 20 is placed on the workpiece support plate 10 from top to bottom, the plurality of snap-in pushing surfaces 10721 can correspondingly push the plurality of snap-in guide surfaces 20312 to drive the plurality of movable plates 2031 to move in the direction of the plurality of telescopic springs 2032. When the plurality of movable plates 2031 automatically move a preset distance in the direction of the plurality of telescopic springs 2032, the plurality of locking slots 20311 can be directly aligned with the plurality of bottom openings. 205. Subsequently, the multiple snap-in pushing surfaces 10721 will correspondingly push past the multiple snap-in guide surfaces 20312, so that the fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 will automatically pass through the multiple locking slots 20311. Similarly, in a moment thereafter, the multiple telescopic springs 2032 will elastically reset, so that the multiple locking slots 20311 will be repositioned to the multiple bottom openings 205. At this time, the fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 will be locked and fixed by the multiple locking slots 20311.

[0142] As described above, this application sets multiple sets of the snap-in pushing surfaces 10721 and snap-in guiding surfaces 20312 in relative positions. Under the guidance of the multiple snap-in guiding surfaces 20312, the multiple snap-in pushing surfaces 10721 can push and squeeze the snap-in pushing surfaces 10721 more easily, so that the snap-in pushing surfaces 20312 can be squeezed through the multiple snap-in guiding surfaces 20312 more easily. As a result, the fixing parts on the upper part of the multiple inverted L-shaped fixing buckles 107 can be quickly locked and fixed by the multiple locking slots 20311.

[0143] Therefore, through the above-mentioned optimized design, the overall performance of this application can be optimized.

[0144] It should be added that, in specific implementation, according to an embodiment of the present invention, multiple flat spring sheets 2000 that need to be fixed are provided in this application, and correspondingly, multiple sets of screw holes 102, lifting ports 103 and lifting inclined wedges 30 are provided.

[0145] Other embodiments, etc., will not be described here.

[0146] In summary, the wedge anti-rotation fixing mechanism 1000 provided in this application first raises the liftable wedge 30 to its highest position and places the flat spring 2000 on the placement position 101, so that the fixing hole 50 is aligned with the screw hole 102. Then, the mobile phone back cover 3000 is placed on the workpiece support plate 10 and pressed and fixed by the workpiece pressure plate 20. At this time, the fixing hole 50 will be aligned with and tightly attached to the screw hole 60. Subsequently, the liftable wedge 30 is lowered along the lifting port 103 by a preset stroke. At this time, the abutment surface 30a will move in the direction of the first long side of the flat spring 2000 to abut against the workpiece support plate 102. Following the first long side of the flat spring 2000, the necessary fastening bolts 40 are then screwed into the fixing hole 50 and the corresponding screw hole 60 through the screw hole 102 from bottom to top to lock the flat spring 2000 to the bottom surface of the phone back cover 3000. During this operation, the abutment surface 30a will always press against the first long side of the flat spring 2000, making it difficult for the flat spring 2000 to rotate during the fixing process. Its anti-rotation effect is good, so it can be accurately fixed in the preset position. This eliminates the need for subsequent fine-tuning of its fixing position, which not only saves time and effort and reduces labor costs, but also greatly shortens the product assembly and production cycle.

[0147] Furthermore, by setting up this application, it is ensured that it is highly practical and effective in use, thus possessing significant market promotion value and becoming very popular. This application is also expected to achieve effective popularization.
