Description

Technical Field

[0001] This invention relates to the field of auxiliary processing technology for mobile phone casings, specifically to a multi-dimensional adaptive structure mobile phone casing positioning and clamping device and its usage method. Background Technology

[0002] Mobile phone cases are components that protect the main body of the phone and enhance its appearance. Their structures come in various forms, including straight, curved, and folding, and their sizes and thicknesses also vary. Mobile phone cases are used in the production and assembly of various smartphones. They not only cushion external impacts and prevent scratches on the body, but also enhance product recognition through personalized designs. They are one of the core components with the largest production volume and the most diverse categories in the smartphone industry chain, and have strict requirements for production and processing precision.

[0003] The multi-dimensional adaptive structure mobile phone shell positioning and clamping device is an auxiliary device in the processing of mobile phone shells. It is mainly used in grinding, polishing and spraying processes. It can quickly and accurately position and firmly clamp the mobile phone shell. Its core function is to fix the position of the workpiece and avoid displacement during processing. At the same time, it can be adapted to shells of different specifications and sizes, taking into account clamping stability and ease of operation. It is a key device to ensure processing accuracy and improve production efficiency.

[0004] Currently, most mobile phone casing positioning and clamping devices on the market consist of a fixed clamp and a positioning structure. During use, the mobile phone casing is positioned by a preset clamping distance and clamping force. In order to improve clamping stability, existing technologies use rigid clamping arms with rubber pads for fixation. At the same time, in order to adapt to different sizes of casings, a manual adjustment of the slider distance is used. However, this method is difficult to adapt to mobile phone casings of various sizes and there is a lack of synchronization of clamping actions in different dimensions, which leads to stress concentration and positioning offset of the casing, affecting processing accuracy and product yield, thereby reducing the applicability and reliability of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-dimensional adaptive structure mobile phone shell positioning and clamping device and its usage method, which solves the problem that the clamp cannot adapt to products of various specifications and that clamping actions in different dimensions are not synchronized.

[0010] Preferably, the fixing assembly includes multiple limiting shells, one end of each limiting shell is fixedly connected to one end of a corresponding rotating rod, the top of each limiting shell is provided with a sliding groove, a support rod is slidably connected inside each limiting shell, a connecting rod is fixedly connected to the top of each support rod, the outer wall of each connecting rod is slidably connected to the inner wall of the corresponding sliding groove, an eccentric wheel is rotatably connected to one side of the outer wall of each connecting rod, and a handle is fixedly connected to one side of the outer wall of each eccentric wheel.

[0011] Preferably, the fixing assembly further includes a plurality of screws, the outer walls of the plurality of screws being threadedly connected to the inner walls of the corresponding support rods, the bottoms of the plurality of screws being slidably connected to a sliding sleeve, the interiors of the plurality of sliding sleeves being fixedly connected to a spring, the tops of the plurality of springs being fixedly connected to the bottoms of the corresponding screws.

[0012] Preferably, the bracket has limiting grooves on all four sides of its top, and the bottoms of the plurality of movable shells one and two are slidably connected to the inner walls of the corresponding limiting grooves, and the bottoms of the plurality of movable shells one and two are fixedly connected to the tops of the corresponding sliding plates.

[0013] Preferably, the top of the mounting platform is fixedly connected to slide rails on all four sides, and a slider is slidably connected to one side of the top of each of the slide rails. The top of each slider is fixedly connected to one side of a corresponding sliding plate.

[0015] Preferably, one end of each of the plurality of wedge blocks 1 penetrates one side of the inner wall of the corresponding groove, and the inclined surfaces of the plurality of wedge blocks 1 and wedge blocks 2 are in contact.

[0016] The method of using the multi-dimensional adaptive structure mobile phone shell positioning and clamping device includes the following steps:

[0017] S1. When preparing for loading and positioning, place the mobile phone shell to be processed on the top of the bracket. At this time, the top block and the limiting pin in the limiting mechanism extend out of the pin hole to form an enclosed positioning area, which initially limits the mobile phone shell to prevent loading deviation. According to the size and structure of the shell, slide the support rod along the limiting shell to the target pressing position and then turn the handle in the opposite direction to lock the support rod through the eccentric wheel. At the same time, rotate the screw to drive the sliding sleeve to move up and down to adjust to the pressing position that matches the height of the shell.

[0018] S2. The output end of cylinder one drives the moving frame to descend. The moving frame pulls the surrounding sliding plates along the slide rail synchronously towards the center through the connecting block. The sliding plates drive moving shell one and moving shell two to slide towards the center along the limiting groove. According to the shell size, the position of clamping block one and clamping block two is adjusted by cylinder two of the avoidance mechanism so that clamping block one or clamping block two can achieve multi-directional synchronous clamping of the mobile phone shell. When moving shell one moves, it drives the rotating rod to swing around the support block, so that the sliding sleeve approaches and presses from the top of the shell. Spring one inside the sliding sleeve generates elastic buffer.

[0019] S3. When it is necessary to avoid a specific area during the processing, the cylinder two on the corresponding moving shell is activated. The cylinder two pulls the rack two to move in its own direction. The rack one moves in the opposite direction through meshing, causing the clamping block two to retract into the moving shell one and the moving shell two to avoid the gap. The clamping block one extends to continue to clamp the unprocessed area, ensuring a stable connection between processing and clamping. During processing, the moving shell in the limiting mechanism drives the wedge one to squeeze the wedge two, causing the limiting pin and the top block to retract into the pin hole to avoid interference with processing.

[0020] S4. After processing, the control cylinder 1 drives the moving frame to rise, the connecting block pushes the sliding plate to separate in all directions, the moving shell 1 and the moving shell 2 slide outwards synchronously, the rotating rod swings to make the sliding sleeve disengage from the top of the shell, the clamping block 1 and the clamping block 2 release the shell, after the moving shell 1 and the moving shell 2 separate, the wedge block 1 disengages from the wedge block 2, the spring 2 pushes the linkage rod to reset, the top block drives the limit pin to extend out of the pin hole, and synchronously lifts the bottom of the mobile phone shell to form a gap, so that the processed shell can be taken out.

[0021] This invention provides a multi-dimensional adaptive structure mobile phone casing positioning and clamping device and its usage method. It has the following beneficial effects:

[0022] 1. This invention uses a cylinder to drive the moving frame to rise and fall, and the connecting block converts the vertical movement into the horizontal movement of the sliding plate. When the moving frame descends, the connecting block pushes the sliding plate to converge towards the center, causing the first and second moving shells to slide along the limiting groove. The movement of the first moving shell causes the rotating rod to swing, so that the sliding sleeve presses the shell from the top, realizing multi-directional synchronous clamping, and adapting to the clamping needs of mobile phone shells of different sizes and structures.

[0023] 2. This invention uses cylinder two to pull rack two to move, and then gear meshing drives rack one to move in the opposite direction, causing clamping block two to retract and avoid the obstruction, while clamping block one extends to continue clamping. This achieves a connection between avoidance and clamping. For shells of different sizes, by adjusting the extension and retraction of cylinder two, when rack two is pushed out, smaller shells are clamped, and when rack two is pulled out, the clamping range is expanded to clamp larger shells. This invention can adapt to various sizes and processing areas and flexibly avoid obstruction.

[0024] 3. In this invention, the top block and the limiting pin extend out of the pin hole to form a positioning area, ensuring that the outer shell is placed in the preset processing position. After clamping is started, the moving shell drives the wedge block one to squeeze the wedge block two, overcoming the tension of the spring two to retract the limiting pin, thus avoiding interference with processing. After processing is completed, the moving shell separates to disengage the wedge block one, and the spring two pushes the linkage rod to reset. The top block and the limiting pin extend out to lift the outer shell, forming a gap for quick removal of parts and preventing friction and scratches. Attached Figure Description

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Reference Figure 2 , Figure 5 and Figure 6 This invention provides a multi-dimensional adaptive structure mobile phone shell positioning and clamping device and its usage method, including a bracket 1, a clamping mechanism 2 at the bottom of the bracket 1 for clamping the mobile phone shell from multiple directions, a movable shell 6 on the left and right sides of the top of the bracket 1, and a movable shell 10 on the front and rear sides of the top of the bracket 1, and an avoidance mechanism 3 inside the two movable shells 6 and the movable shell 10 for avoiding the clamping part from obstructing the processing, and a cavity 7 inside the bracket 1, with a limiting mechanism 4 inside the cavity 7 for limiting the placement area when loading the mobile phone shell;

[0037] The clamping mechanism 2 includes a mounting platform 21, the top of which is fixedly connected to the bottom of the bracket 1. The mounting platform 21 is used to fix the cylinder 22 and the slide rail 8. The bottom of the mounting platform 21 is fixedly connected to the cylinder 22, which drives the lifting and lowering of the movable frame 23. The output end of the cylinder 22 is fixedly connected to the movable frame 23. The movable frame 23 transmits the vertical power of the cylinder 22 to the connecting block 24, changing the direction of movement. The top of the movable frame 23 is rotatably connected to the connecting block 24 on all four sides. The connecting block 24 realizes the rotatable connection between the movable frame 23 and the sliding plate 25, converting the vertical movement into horizontal movement. The top of the mounting platform 21 is provided with the sliding plate 25 on all four sides. The sliding plate 25 drives the movable shell to move synchronously, transmitting the clamping power. The other ends of multiple connecting blocks 24 are rotatably connected to the bottom of the corresponding sliding plate 25. Support blocks 27 are provided on the front and rear sides of the two movable shells 6. The support blocks 27 provide rotation support points for the rotating rod 28 to ensure the stable swing of the rotating rod 28. The bottom of multiple support blocks 27 is fixedly connected to the top of the bracket 1. Rotating rods 28 are rotatably connected to the inner side of multiple support blocks 27. The rotating rods 28 convert the horizontal movement of the movable shell into a top pressing action. Rotating shafts 26 are rotatably connected to the top of the two movable shells 6. The rotating shafts 26 connect the movable shell and the rotating rod 28 and transmit the movement of the movable shell to the rotating rod 28. One side of multiple rotating shafts 26 is fixedly connected to the corresponding rotating rod 28. One end of multiple rotating rods 28 is provided with a fixing component 29.

[0038] The fixing assembly 29 includes multiple limiting shells 291, which provide sliding guidance and mounting base for the support rod 292. One end of each limiting shell 291 is fixedly connected to one end of a corresponding rotating rod 28. Each limiting shell 291 has a sliding groove 293 on its top, which limits the sliding trajectory of the connecting rod 294, ensuring smooth movement of the support rod 292. Support rods 292 are slidably connected inside each limiting shell 291, and the support rods 292 drive the sliding sleeve 298 to move. Each support rod 292 has a connecting rod 294 fixedly connected to its top. The connecting rod 294 is used to connect the support rod 292 and the eccentric wheel 295 to achieve position locking operation. The outer walls of the multiple connecting rods 294 are slidably connected to the inner walls of the corresponding slide grooves 293. An eccentric wheel 295 is rotatably connected to one side of the outer wall of the multiple connecting rods 294. The eccentric wheel 295 achieves the pressing, locking and releasing adjustment of the support rod 292 by rotation. A handle 296 is fixedly connected to one side of the outer wall of the multiple eccentric wheels 295.

[0039] The fixing component 29 also includes multiple screws 297. The outer walls of the multiple screws 297 are threadedly connected to the inner walls of the corresponding support rods 292. The screws 297 adjust the height of the sliding sleeves 298 through threaded transmission to achieve the matching of the clamping height. The bottom of each of the multiple screws 297 is slidably connected to the sliding sleeves 298. The sliding sleeves 298 directly contact the top of the outer shell to transmit the clamping force. The inside of each of the multiple sliding sleeves 298 is fixedly connected to a spring 299. The spring 299 provides elastic cushioning to avoid deformation of the outer shell caused by rigid clamping. The top of each of the multiple springs 299 is fixedly connected to the bottom of the corresponding screws 297.

[0040] Specifically, the output end of cylinder 22 drives the moving frame 23 to move vertically up and down. The moving frame 23 converts its vertical movement into the horizontal movement of the sliding plate 25 through the connecting block 24. When the moving frame 23 descends, the connecting block 24 pulls the surrounding sliding plates 25 to converge towards the center. The sliding plates 25 drive the moving shell 6 and the moving shell 10 to slide towards the center along the limiting groove 5. During the movement of the moving shell 6, the rotating rod 28 swings around the support block 27 and is pressed from the top of the phone shell through the sliding sleeve 298. When the pressing position needs to be adjusted, the handle 296 is turned to drive the eccentric wheel 2. Rotating 95 degrees releases the clamping force between the eccentric wheel 295 and the top of the limiting shell 291, allowing the support rod 292 to slide along the inner wall of the limiting shell 291. After adjustment, rotating the handle 296 in the opposite direction causes the eccentric wheel 295 to press the top of the limiting shell 291 again, locking the position of the support rod 292 through friction. When adjusting the clamping height, rotating the screw 297 drives the sliding sleeve 298 to move up and down along the axis of the support rod 292. When the sliding sleeve 298 contacts the phone casing, the spring 299 absorbs the clamping impact force through elastic deformation, avoiding casing deformation caused by rigid contact and improving the clamping stability of casings with different structures.

[0041] Reference Figure 1 , Figure 5 and Figure 7The avoidance mechanism 3 includes multiple sliding rods 31. The outer walls of the multiple sliding rods 31 are slidably connected to the inner walls of the corresponding movable shell 1 6 and movable shell 2 10. Each sliding rod 31 is equipped with a clamping block 1 32 and a rack 1 33, enabling the extension and retraction of the clamping block 1 32. Clamping blocks 1 32 are fixedly connected to both ends of one side of each of the multiple sliding rods 31, and rack 1 33 is fixedly connected to the other side of each of the multiple sliding rods 31. The rack 1 33 meshes with a gear 34 to transmit the extension and retraction power of the sliding rods 31. Gears 34 are rotatably connected to the inner center of each of the two movable shells 1 6 and movable shell 2 10, enabling the rack 1 33 to mesh with the rack 2 35. Reverse linkage, changing the direction of movement, multiple slide rods 31 are slidably connected to rack 2 35 inside, rack 2 35 is connected to cylinder 2 37, driving clamping block 2 36 to extend and retract, multiple rack 1 33 and rack 2 35 are respectively meshed with corresponding gears 34, clamping block 2 36 is fixedly connected to one side of multiple rack 2 35, cylinder 2 37 is fixedly connected to one side of two movable shell 1 6 and movable shell 2 10, cylinder 2 37 provides power to avoidance mechanism 3, the output end of multiple cylinder 2 37 passes through the outer wall of corresponding movable shell 1 6 and movable shell 2 10 and is fixedly connected to the other side of rack 2 35;

[0042] The dimensions of multiple clamping blocks 36 are matched with the inner wall dimensions of the slide bar 31, and one side of multiple clamping blocks 32 and clamping blocks 36 penetrates the inner wall of the corresponding movable shell 6 and movable shell 10.

[0043] Specifically, the output end of cylinder 2 37 pulls rack 2 35 to slide along the inner wall of the moving shell. Rack 2 35 meshes with gear 34, causing gear 34 to rotate. This causes rack 1 33 on the other side of gear 34 to slide in the opposite direction. The slide rod 31, which is fixedly connected to rack 1 33, moves synchronously with rack 1 33, causing clamping blocks 1 32 at both ends of slide rod 31 to extend out of the moving shell. Meanwhile, clamping block 2 36, which is fixed to rack 2 35, retracts into slide rod 31, achieving the switching between avoidance and clamping. For shells of different sizes, the extension and retraction of cylinder 2 37 can be slightly adjusted. When clamping a small shell, cylinder 2 37 pushes rack 2 35 to extend, and clamping block 2 36 protrudes and contacts the shell for clamping. When clamping a large shell, cylinder 2 37 pulls rack 2 35 to retract, expanding the clamping range. While adjusting the extension and retraction of cylinder 2 37, the position of clamping block 1 32 is ensured not to affect processing.

[0044] Reference Figure 2 , Figure 3 and Figure 8The limiting mechanism 4 includes multiple wedges 41, one side of which is fixedly connected to the bottom side of the corresponding movable shell 6 and movable shell 10. The wedges 41 move with the movable shell, and the pressure of the wedges 44 causes the limiting pins 43 to retract. The top of the bracket 1 has multiple pin holes 42, which provide installation and sliding channels for the limiting pins 43. The inner walls of the multiple pin holes 42 are slidably connected to the limiting pins 43, forming a feeding positioning area to achieve pre-positioning of the shell. The bottom of the multiple limiting pins 43 is fixedly connected to the wedges 44. Through the pressure of the wedges 41, the limiting pins 43 are driven to move up and down. Each of the two wedges 44 has a top block 47 fixedly connected to one side of its top. The top block 47 is used to lift the workpiece during reset. The outer walls of the multiple top blocks 47 are slidably connected to the other side of the inner wall of the corresponding pin hole 42. A linkage rod 45 is provided inside the cavity 7. The linkage rod 45 connects the multiple wedges 44 to ensure that the limit pin 43 moves synchronously. The outer walls of the multiple linkage rods 45 are fixedly connected to one end of the corresponding wedge 44. Springs 46 are fixedly connected to the bottom of the linkage rods 45. Springs 46 provide reset force so that the top block 47 extends out after processing to lift the outer shell. The bottom of the multiple springs 46 is fixedly connected to the bottom of the cavity 7.

[0045] One end of each of the multiple wedges 41 penetrates one side of the inner wall of the corresponding groove 293, and the multiple wedges 41 are in contact with the inclined surface of the wedges 44.

[0046] Specifically, during loading, the top block 47 and the limiting pin 43 extend from the top of the pin hole 42. The enclosed area formed by multiple limiting pins 43 initially positions the mobile phone casing. When the clamping mechanism 2 is activated, the first movable casing 6 and the second movable casing 10 move towards the center. The first wedge 41 at the bottom moves synchronously and passes through the slide groove 293 to fit against the inclined surface of the second wedge 44. As the movable casing continues to move, the first wedge 41 generates a downward component force through the inclined surface compression, causing the second wedge 44 to overcome the tension of the second spring 46 and move downward. The linkage rod 45 drives all the limiting pins 43 and the top block 47 to retract into the pin hole 42 synchronously, avoiding interference of the limiting pins 43 with the processing. After processing is completed, the movable casing separates to the outside, the first wedge 41 disengages from the second wedge 44, the tension of the second spring 46 drives the linkage rod 45 to reset, and the second wedge 44 rises, causing the top block 47 and the limiting pin 43 to extend, synchronously lifting the bottom of the casing to form a small gap, which facilitates quick removal of the part.

[0047] Reference Figure 1 , Figure 2 and Figure 4The bracket 1 has limit grooves 5 on all four sides of its top. The bottoms of multiple movable shells 1 6 and 2 10 are slidably connected to the inner walls of the corresponding limit grooves 5. The limit grooves 5 limit the sliding direction of the movable shells 1 6 and 2 10 to ensure the stability of the horizontal movement of the movable shells. The bottoms of multiple movable shells 1 6 and 2 10 are fixedly connected to the top of the corresponding sliding plates 25. The mounting platform 21 has slide rails 8 fixedly connected on all four sides of its top. The slide rails 8 provide sliding guides for the sliders 9 to ensure the stability of the movement of the sliding plates 25. The tops of multiple slide rails 8 are slidably connected to one side of the top of each slider 9. The sliders 9 are used to connect the sliding plates 25 and the slide rails 8. The tops of multiple sliders 9 are fixedly connected to one side of the corresponding sliding plates 25.

[0048] Specifically, the limiting groove 5 at the top of the bracket 1 forms a sliding fit with the bottom of the first movable shell 6 and the second movable shell 10, which limits the movable shell to only make linear movements in the horizontal direction, either close to or away from the center, thus preventing the movable shell from deviating or shaking during the movement. When the cylinder 22 drives the movable frame 23 to rise and fall, the connecting block 24 drives the sliding plate 25 to move. The cooperation between the slide rail 8 and the slider 9 provides stable support and guidance for the sliding plate 25. At the same time, the movement of the sliding plate 25 is transmitted to the movable shell through the fixed connection, ensuring the synchronicity of the movement of the movable shell.

[0049] Example 2:

[0050] The method of using the multi-dimensional adaptive structure mobile phone shell positioning and clamping device includes the following steps:

[0051] S1. When preparing for loading and positioning, place the mobile phone shell to be processed on the top of the bracket 1. At this time, the top block 47 and the limiting pin 43 in the limiting mechanism 4 extend out of the pin hole 42 to form an enclosed positioning area, which initially limits the mobile phone shell to prevent loading deviation. According to the shell size and structure, slide the support rod 292 along the limiting shell 291 to the target pressing position and then rotate the handle 296 in the opposite direction to lock the support rod 292 through the eccentric wheel 295. At the same time, rotate the screw 297 to drive the sliding sleeve 298 to move up and down to adjust to the pressing position that matches the shell height.

[0052] S2, the output end of cylinder 1 22 drives the moving frame 23 to descend. The moving frame 23 pulls the surrounding sliding plates 25 along the slide rail 8 synchronously towards the center through the connecting block 24. The sliding plates 25 drive the moving shell 1 6 and the moving shell 2 10 to slide towards the center along the limiting groove 5. According to the shell size, the position of clamping block 1 32 and clamping block 2 36 is adjusted by cylinder 2 37 of the avoidance mechanism 3 so that clamping block 1 32 or clamping block 2 36 can achieve multi-directional synchronous clamping of the mobile phone shell. When the moving shell 1 6 moves, it drives the rotating rod 28 to swing around the support block 27, so that the sliding sleeve 298 approaches and presses from the top of the shell. The spring 1 299 inside the sliding sleeve 298 generates elastic buffer.

[0053] S3. When it is necessary to avoid a specific area during processing, the cylinder 37 on the corresponding moving shell is activated. The cylinder 37 pulls the rack 35 to move in its own direction. The rack 33 moves in the opposite direction through meshing, causing the clamping block 36 to retract into the moving shell 6 and the moving shell 10 to avoid being in the same position. The clamping block 32 extends to continue to clamp the unprocessed area, ensuring a stable connection between processing and clamping. During processing, the moving shell in the limiting mechanism 4 drives the wedge 41 to squeeze the wedge 44, causing the limiting pin 43 and the top block 47 to retract into the pin hole 42 to avoid interfering with processing.

[0054] S4. After processing, the control cylinder 22 drives the moving frame 23 to rise, the connecting block 24 pushes the sliding plate 25 to separate to all sides, the moving shell 6 and the moving shell 10 slide outwards synchronously, the rotating rod 28 swings to make the sliding sleeve 298 disengage from the top of the shell, the clamping block 32 and the clamping block 36 release the shell, after the moving shell 6 and the moving shell 10 are separated, the wedge 41 disengages from the wedge 44, the spring 46 pushes the linkage rod 45 to reset, the top block 47 drives the limit pin 43 to extend out of the pin hole 42, and simultaneously lifts the bottom of the mobile phone shell to form a gap, so that the processed shell can be taken out.

[0055] Working principle: When the clamping mechanism 2 is activated, the output end of cylinder 22 drives the moving frame 23 to rise and fall vertically. The moving frame 23 converts the vertical motion into the horizontal motion of the sliding plate 25 through the connecting block 24. When the moving frame 23 descends, the connecting block 24 pushes the surrounding sliding plates 25 to converge towards the center synchronously. The sliding plates 25 drive the moving shell 6 and the moving shell 10 to slide towards the center along the limiting groove 5. The mobile phone shell on the top of the bracket 1 is clamped synchronously from multiple directions by clamping block 32 or clamping block 36. When the moving frame 23 rises, the connecting block 24 pulls the sliding plates 25 to separate them from the surrounding areas, completing the release. When the moving shell 6 moves, it drives the rotating rod 28 to swing around the support block 27. When the screw 297 and the sliding sleeve 298 approach and press together from the top of the outer shell, and the pressing position needs to be adjusted, turn the handle 296 to release the eccentric wheel 295. After the support rod 292 slides along the limiting shell 291 to the target position, turn the handle 296 in the opposite direction to lock the position of the support rod 292 through the eccentric wheel 295. When adjusting the height, turn the screw 297 to drive the sliding sleeve 298 to move up and down through the threaded transmission. The spring 299 inside the sliding sleeve 298 generates elastic buffer when pressing, adapts to the curvature deviation of the outer shell surface, avoids clamping deformation, ensures stable pressing of outer shells with different structures, realizes multi-directional synchronous clamping, and meets the clamping requirements of mobile phone shells of different sizes and structures.

[0056] Furthermore, when processing requires avoiding a specific area, cylinder 2 37 is activated and pulls rack 2 35 to move in the direction of cylinder 2 37. Rack 2 35 drives rack 1 33 to move in the opposite direction through gear 34. Rack 2 35 drives clamping block 2 36 to retract into the moving shell to avoid obstructing the processing area. Rack 1 33 pushes slide bar 31 to extend clamping block 1 32 to continue clamping the unprocessed area, thus achieving the connection between avoidance and clamping. For shells of different sizes, the clamping range can be adjusted by adjusting the extension and retraction of cylinder 2 37. When clamping a small shell, cylinder 2 37 pushes rack 2 35 to extend for clamping. When clamping a large shell, cylinder 2 37 pulls rack 2 35 to retract, expanding the clamping range. While adjusting the extension and retraction of cylinder 2 37, it is necessary to ensure that the position of clamping block 1 32 does not affect processing, thus achieving multi-size compatibility and flexible avoidance of processing areas.

[0057] In the final loading stage, the top block 47 and the limiting pin 43 extend out of the pin hole 42 to form a positioning area, ensuring that the mobile phone casing is placed in the preset processing area and avoiding loading deviation. After the clamping operation is started, the moving shell 1 6 and the moving shell 2 10 drive the wedge block 1 41 to move synchronously. The wedge block 1 41 penetrates the inner wall of the slide groove 293 and squeezes the wedge block 2 44 through the inclined surface, causing the wedge block 2 44 to move downward against the tension of the spring 2 46. The linkage rod 45 drives all the limiting pins 43 and the top block 47 to retract into the pin hole 42 to avoid interference with processing. After processing is completed, the moving shell separates to the outside, the wedge block 1 41 disengages from the wedge block 2 44, the spring 2 46 pushes the linkage rod 45 to reset, and the top block 47 and the limiting pin 43 extend out of the pin hole 42, synchronously lifting the bottom of the mobile phone casing, so that there is a gap between the casing and the bracket 1, which facilitates quick removal of the part and avoids friction and scratches on the casing when removing the part.

A method for using a multi-dimensional adaptive structure mobile phone casing positioning and clamping device, characterized in that, The mobile phone casing positioning and clamping device with a multi-dimensional adaptive structure according to any one of claims 1-9 includes the following steps: S1. When preparing for loading and positioning, place the mobile phone shell to be processed on the top of the bracket (1). At this time, the top block (47) and the limiting pin (43) in the limiting mechanism (4) extend out of the pin hole (42) to form an enclosed positioning area, which initially limits the mobile phone shell to prevent loading deviation. According to the shell size and structure, slide the support rod (292) along the limiting shell (291) to the target pressing position and then rotate the handle (296) in the opposite direction to lock the support rod (292) through the eccentric wheel (295). At the same time, rotate the screw (297) to drive the sliding sleeve (298) to move up and down to adjust to the pressing position that matches the shell height. S2, the output end of cylinder one (22) drives the moving frame (23) to descend.

According to the shell size, the position of clamping block one (32) and clamping block two (36) is adjusted by cylinder two (37) of the avoidance mechanism (3), so that clamping block one (32) or clamping block two (36) can achieve multi-directional synchronous clamping of the mobile phone shell. When the moving shell one (6) moves, it drives the rotating rod (28) to swing around the support block (27), so that the sliding sleeve (298) approaches and presses from the top of the shell. The spring one (299) inside the sliding sleeve (298) generates elastic buffer. S3. When it is necessary to avoid a specific area during the processing, start the cylinder two (37) on the corresponding moving shell. The cylinder two (37) pulls the rack two (35) to move in its own direction. The rack one (33) moves in the opposite direction through meshing, so that the clamping block two (36) retracts into the moving shell one (6) and the moving shell two (10) to avoid the gap. The clamping block one (32) extends to continue to clamp the unprocessed area, ensuring a stable connection between processing and clamping. During processing, the moving shell in the limiting mechanism (4) drives the wedge one (41) to squeeze the wedge two (44), so that the limiting pin (43) and the top block (47) retract into the pin hole (42) to avoid interference with processing. S4.
