Description

Technical Field

[0001] This invention relates to the field of jigs, and more specifically, to a pressure-holding jig for assembling small parts of a tablet computer back cover. Background Technology

[0002] In the manufacturing process of tablet computers, the assembly of small back shell components is a crucial step. As consumers' demands for tablet computers to be thinner, more portable, and have more diverse appearance designs continue to increase, the structural design of tablet computer back shells has become increasingly complex. They are no longer limited to the traditional flat and simple structure, but have many designs with non-flat features in some areas.

[0003] In the installation process of tablet computer back cover components, the pressure holding process is a crucial step to ensure a firm bond between the component and the back cover, achieving the desired installation effect. Pressure holding typically requires specialized equipment to apply pressure and time, causing the component and back cover to adhere tightly through adhesives or other connection methods, forming a stable and reliable connection structure.

[0004] However, due to the aforementioned uneven structures on the back cover of tablet computers, existing pressure-holding equipment and processes are mostly designed for back covers with traditional flat structures. When applied to back covers with complex local structures, it is difficult to ensure that pressure is applied evenly to all parts of the back cover. During the pressure-holding process, pressure tends to concentrate in flat areas or raised parts of the back cover, while the pressure on recessed areas or structurally complex parts is relatively less. This uneven stress can lead to insufficient adhesion between small parts and the back cover, making it prone to loosening, detachment, and other installation defects during subsequent use, affecting the normal use of the tablet computer. Furthermore, excessive local pressure may damage the back cover, such as causing cracks or deformation, reducing the structural integrity and appearance quality of the back cover, increasing the product defect rate, and raising production costs.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

[0048] The following describes in detail, with reference to the accompanying drawings, a pressure-holding fixture for assembling small components of a tablet computer back cover according to an embodiment of the present invention.

[0049] Reference Figures 1 to 12 As shown, a pressure-holding fixture for assembling small back shell parts of a tablet computer according to an embodiment of the present invention includes a base 10, two locking components 20, a floating component 30, multiple clamping components 40 and a pressure plate 50.

[0050] The base 10 has pads 11 on both sides of its bottom surface, and the pads 11 are suitable for being placed on the conveyor belt.

[0051] The two locking components 20 are disposed opposite to each other on the upper surface of the base 10 and extend along the length of the base 10. The lower ends of the two locking components 20 can rotate along the width of the base 10. Each locking component 20 is provided with a plurality of guide wheels 21, which are distributed at intervals along the length of the locking component 20 to cooperate with the robot arm to push the two locking components 20 to pivot relative to each other.

[0052] The floating component 30 includes two floating plates 31, which are arranged adjacent to each other and are floatingly positioned above the base 10 for placing the tablet computer casing.

[0053] All of the clamping components 40 can be floated up and down on the base 10 to clamp small parts to be assembled. It should be noted that the floating plate 31 is provided with multiple through slots, and the multiple through slots are one-to-one with the multiple clamping components 40, so that the small parts located on the clamping components 40 can contact and adhere to the tablet computer shell.

[0054] The pressure plate 50 is detachably covered above the floating component 30, and both locking components 20 can be rotated and locked on both sides of the pressure plate 50 to press the pressure plate 50 onto the floating component 30.

[0055] Based on the above, by setting pads 11 on opposite sides of the bottom surface of the base 10, it can be placed directly on the conveyor belt, which facilitates the transfer and transportation of the fixture on the production line, realizes rapid movement and positioning in the automated production process, and improves production efficiency. Multiple guide wheels 21 are spaced apart along the length of the locking assembly 20. When the robot pushes the locking assembly 20 to rotate, the guide wheels 21 play a guiding and assisting role, reducing friction and making the rotation process smoother and more precise, reducing the difficulty of operation and equipment wear. The two floating plates 31 of the floating assembly 30 can be floated above the base 10 and can be adaptively adjusted according to the actual shape and size of the shell, effectively dealing with shells of different specifications or with certain tolerances, improving the versatility of the fixture and the assembly quality. Multiple clamping assemblies 40 can be floated up and down on the base 10, which can flexibly clamp small parts to be assembled of different heights and shapes, meet diverse assembly needs, and ensure the positional accuracy and stability of small parts during the assembly process. The pressure plate 50 is detachably covered above the floating assembly 30. The two locking assemblies 20 can rotate and lock on both sides of the pressure plate 50, pressing the pressure plate 50 onto the floating assembly 30, which makes the pressure holding process more stable and reliable, and can provide uniform and continuous pressure to ensure full adhesion between the small parts and the back shell.

[0056] Preferably, in one embodiment of the present invention, both locking components 20 include locking arms 22 and a plurality of locking elements 23.

[0057] The locking arm 22 is U-shaped, and two first mounting grooves 12 are provided on both sides of the upper surface of the base 10. The two first mounting grooves 12 are distributed at intervals along the length direction of the locking assembly 20. The two ends of the locking arm 22 are rotatably connected to the inner sidewall of the first mounting groove 12.

[0058] The locking arm 22 is provided with a plurality of second mounting slots 221, which are spaced apart along the length of the locking arm 22, and the plurality of locking members 23 are detachably connected to the second mounting slots 221 respectively. The lower ends of the plurality of locking members 23 extend below the locking arm 22 to fasten onto the pressure plate 50.

[0059] Thus, the locking arm 22 adopts a U-shaped structure, with its two ends rotatably connected to the inner sidewalls of the first mounting grooves 12 spaced apart along the length of the locking assembly 20 on both sides of the upper surface of the base 10. This allows the locking arm 22 to rotate flexibly, enabling angle adjustment according to actual production needs, facilitating robot operation and cooperation with the pressure plate 50, improving the adaptability and ease of operation of the fixture in automated production processes. Simultaneously, the width of the first mounting grooves 12 also limits the rotation range of the locking arm 22. Multiple second mounting grooves 221 are spaced apart along the length of the locking arm 22, and multiple locking components 23 are detachably connected to these second mounting grooves 221. This detachable structure makes the installation and replacement of the locking components 23 very convenient. When a locking component 23 is damaged or needs adjustment according to different product specifications, it can be quickly replaced without replacing the entire locking assembly 20, reducing maintenance costs and downtime, and improving production efficiency.

[0060] Preferably, in one embodiment of the present invention, the locking member 23 includes a mounting block 231 and a plurality of ball screws 232.

[0061] The mounting block 231 is installed in the second mounting groove 221 by screws. The bottom surface of the mounting block 231 is provided with a plurality of mounting holes 2311, which are distributed at intervals along the length of the locking arm 22.

[0062] Multiple ball screws 232 are disposed one-to-one in the mounting holes 2311.

[0063] The second mounting groove 221 has a through hole 222 on its bottom surface. The through hole 222 and the mounting hole 2311 are arranged opposite to each other. The lower end of the ball screw 232 extends through the through hole 222 to the bottom of the locking arm 22. The upper surface of the pressure plate 50 has multiple locking holes 51 on both sides. When the locking assembly 20 is fastened to both sides of the pressure plate 50, the lower ends of the multiple ball screws 232 slide into the locking holes 51 respectively.

[0064] Thus, the locking component 23 consists of a mounting block 231 and multiple ball screws 232. The mounting block 231 is installed in the second mounting slot 221 by screws. Its modular design makes the installation and removal of the locking component 23 simple and quick. When the locking component 23 needs to be repaired, replaced, or adjusted, it can be done simply by operating the screws, without complicated tools and cumbersome steps, which greatly shortens maintenance time and improves production efficiency. Since the ball screws 232 themselves have a certain degree of elasticity, when the locking assembly 20 is fastened to both sides of the pressure plate 50, the lower end of the ball screws 232 can smoothly slide into the locking holes 51 on both sides of the upper surface of the pressure plate 50. During the pressure holding process, the elastic force of the ball screws 232 can provide a continuous and stable locking force, ensuring a tight connection between the locking assembly 20 and the pressure plate 50, preventing the pressure plate 50 from loosening or shifting due to external forces, thereby ensuring the uniformity and stability of the pressure holding pressure and effectively improving the assembly quality of the small parts and the back shell.

[0065] Meanwhile, due to the tolerance capability of the fit between the ball screw 232 and the locking hole 51, the locking component 23 is designed to adapt to the assembly needs of tablet computer back covers and small parts of different specifications. During the production process, even if there is a certain dimensional deviation between the pressure plate 50 and the locking component 20, the ball screw 232 can smoothly slide into the locking hole 51 through its own elastic adjustment, achieving a reliable locking function and improving the versatility and adaptability of the fixture.

[0066] Preferably, in one embodiment of the present invention, a plurality of first springs 311 are distributed on the bottom surface of the floating plate 31, and the lower ends of the plurality of first springs 311 are connected to the upper surface of the base 10.

[0067] Thus, multiple first springs 311 provide elastic support for the floating plate 31, allowing it to float within a certain range. When placing tablet PC housings of different specifications, shapes, or with certain dimensional tolerances, the floating plate 31 can automatically adjust according to the actual contour of the housing, ensuring a tight fit between the housing and the floating plate 31. This improves the fixture's adaptability to different products and reduces assembly problems caused by differences in housing dimensions. During the pressure holding process, the pressure plate 50 applies pressure to the floating plate 31, and the multiple first springs 311 can evenly distribute the pressure across the entire floating plate 31. This avoids excessive local stress on the housing due to pressure concentration, preventing deformation or damage. It also ensures uniform pressure between the small parts and the housing, resulting in more thorough and secure adhesion, and improving the reliability and stability of the assembly.

[0068] Preferably, in one embodiment of the present invention, a plurality of positioning elements 32 are further included, each of the plurality of positioning elements 32 including a positioning pin 321, a first clamping screw 322, a positioning seat 323 and a second clamping screw 324.

[0069] The floating plate 31 is provided with a first insertion hole 312, and the positioning pin 321 is inserted into the first insertion hole 312. The positioning pin 321 is provided with a first limiting platform 3211 on its side.

[0070] The first insertion hole 312 has a first threaded hole 313 on one side, and the first clamping screw 322 is disposed in the first threaded hole 313. The nut side of the first clamping screw 322 presses against the first limiting platform 3211 to restrict the positioning pin 321 in the insertion hole.

[0071] The base 10 is provided with a second insertion hole 13, and the second insertion hole 13 and the first insertion hole 312 are arranged vertically opposite each other. The positioning seat 323 is provided in the second insertion hole 13. The positioning seat 323 is provided with a positioning hole 3231. The lower end of the positioning pin 321 is inserted into the positioning hole 3231. The side of the positioning seat 323 is provided with a second limiting platform 3232.

[0072] A second threaded hole 14 is provided on one side of the second insertion hole 13. The second clamping screw 324 is located in the second threaded hole 14, and the nut side of the second clamping screw 324 presses against the second limiting platform 3232 to restrict the positioning seat 323 within the second insertion hole 13.

[0073] Thus, the positioning pin 321 is inserted into the first insertion hole 312 of the floating plate 31, and its lower end is inserted into the positioning hole 3231 of the positioning seat 323 on the base 10, with the first insertion hole 312 and the second insertion hole 323 being arranged vertically opposite each other. This achieves precise vertical positioning of the floating plate 31 and the base 10, ensuring that the position of the floating plate 31 relative to the base 10 remains fixed during assembly and pressure holding. It provides a stable and accurate reference for the housing and small parts to be assembled placed on the floating plate 31, effectively improving the accuracy of the assembly of small parts and housing, reducing assembly deviations, and improving product quality. The first limiting platform 3211 on the side of the positioning pin 321 cooperates with the first clamping screw 322, and the second limiting platform 3232 on the side of the positioning seat 323 cooperates with the second clamping screw 324, respectively limiting the movement of the positioning pin 321 in the first insertion hole 312 of the floating plate 31 and the positioning seat 323 in the second insertion hole 13 of the base 10.

[0074] Meanwhile, the positioning component 32 adopts a combination of positioning pin 321, first clamping screw 322, positioning seat 323, and second clamping screw 324. The components are installed through simple plug-in and threaded connections. This makes the installation and disassembly of the positioning component 32 very convenient. Operators can quickly complete the assembly and replacement of the positioning component 32 without complicated tools and cumbersome steps, which greatly shortens the preparation and maintenance time of the fixture and improves production efficiency.

[0075] Preferably, in one embodiment of the present invention, each of the plurality of clamping components 40 includes a guide frame 41, a tray 42, and a floating platform 43.

[0076] The base 10 is provided with a third mounting groove 15, and the guide frame 41 is disposed in the third mounting groove 15.

[0077] The support plate 42 is disposed on the bottom surface of the base 10 and is opposite to the third mounting groove 15, for supporting the guide frame 41.

[0078] The floating platform 43 is located inside the guide frame 41 and is slidably connected to the guide frame 41. The bottom surface of the floating platform 43 is connected to the support plate 42 by multiple second springs 44 so that the floating platform 43 sinks when it is pressed. The surface of the floating platform 43 is provided with a workpiece groove 431 for placing the workpiece to be assembled.

[0079] Thus, by setting the guide frame 41 within the third mounting slot 15 of the base 10, a precise moving track is provided for the floating stage 43. This ensures that the floating stage 43 always moves in the predetermined direction during sliding, without deviation or wobbling, thereby guaranteeing that the workpiece to be assembled placed in the workpiece slot 431 of the floating stage 43 can be accurately positioned in the designated location. The support plate 42 is set on the bottom surface of the base 10 and opposite to the third mounting slot 15, providing a stable support for the guide frame 41 and ensuring its stable installation. The floating stage 43 is connected to the support plate 42 via multiple second springs 44, allowing it to sink when subjected to pressure. This enables the clamping assembly 40 to adapt to workpieces of different heights or shapes, as well as minor dimensional changes that may occur during assembly. For example, when there is a certain height difference or unevenness on the surface of the placed workpiece, the floating stage 43 can automatically adjust the sinking depth according to the actual situation, ensuring a tight fit between the workpiece and the assembly components, and improving assembly quality. The workpiece groove 431 on the surface of the floating table 43 provides a dedicated placement position for the workpiece to be assembled, and the operator can easily put the workpiece into the workpiece groove 431.

[0080] Preferably, in one embodiment of the present invention, the floating platform 43 is provided with two sliding grooves 432, the two sliding grooves 432 are arranged perpendicularly to each other, and one end of each groove extends into the workpiece groove 431.

[0081] Each of the two slide grooves 432 is provided with a clamping block 433, and the two clamping blocks 433 can slide along the length direction of the slide groove 432 to clamp the workpiece in the workpiece groove 431.

[0082] Thus, by setting two mutually perpendicular slides 432, the clamping block 433 can clamp the workpiece placed in the workpiece slot 431 from two mutually perpendicular directions. This multi-directional clamping method can more accurately fix the position of the workpiece, ensuring that the workpiece does not shift during assembly and pressure holding. Since the clamping block 433 can slide along the length of the slide 432, it can be adjusted according to the actual shape and size of the workpiece. Whether the workpiece is square, rectangular, or other irregularly shaped, the two clamping blocks 433 can be moved appropriately to fit tightly against the edge of the workpiece, achieving effective clamping of workpieces of different specifications. This enhances the versatility and adaptability of the fixture, reducing the trouble and cost of changing fixtures due to differences in workpiece size.

[0083] Preferably, in one embodiment of the present invention, each of the two clamping blocks 433 is provided with a third insertion hole 4331 at its tail end, a third spring 434 is provided in the third insertion hole 4331, and a stop block 435 is provided at the other end of each of the sliding grooves 432, with one end of the third spring 434 connected to the stop block 435.

[0084] Thus, since one end of the third spring 434 is connected to the stop block 435 and the other end is placed in the third insertion hole 4331 at the tail end of the clamping block 433, under natural conditions, the spring force will cause the clamping block 433 to always maintain a tendency to move towards the workpiece groove 431. When the workpiece is placed, the clamping block 433 is driven away from the workpiece groove 431, and the spring is compressed; once the workpiece is placed, the driving force of the clamping block 433 is released, and the spring force will automatically push the clamping block 433 closer to the workpiece, realizing automatic clamping. There is no need for the operator to manually adjust the clamping blocks 433 one by one, which greatly improves the clamping efficiency.

[0085] Preferably, in one embodiment of the present invention, both of the bottom surfaces of the sliding grooves 432 are provided with a retraction groove 4321, the retraction groove 4321 extends through to the bottom surface of the floating platform 43, and the support plate 42 is provided with a hollow groove 421, the hollow groove 421 and the retraction groove 4321 are arranged opposite to each other.

[0086] Both clamping blocks 433 have a driving groove 4332 on their bottom surfaces. The driving groove 4332, the hollow groove 421, and the retraction groove 4321 are arranged opposite to each other so that the driving device can extend into the driving groove 4332 to drive the clamping block 433 and control the clamping and releasing of the clamping block 433.

[0087] Thus, by setting the corresponding drive groove 4332, hollow groove 421 and retraction groove 4321, the drive device can smoothly extend into the drive groove 4332 on the bottom surface of the clamping block 433 through the hollow groove 421 and retraction groove 4321 to directly drive the clamping block 433, thereby controlling the clamping and loosening of the clamping block 433.

[0088] Preferably, in one embodiment of the present invention, the base 10 is provided with slots 16 on all four sides to facilitate the insertion of a robotic arm into the slots 16 to transfer the entire fixture.

[0089] Thus, by providing the locking holes 16 on the side of the base 10, the robotic arm can quickly and accurately insert into the locking holes 16 to transfer the fixture from one workstation to another, greatly shortening the transfer time of the fixture between processes. Compared with manual handling, the robotic arm has a faster transfer speed and is not affected by factors such as fatigue, enabling continuous and uninterrupted operation, thereby effectively improving the production rhythm and efficiency of the entire production line.
