Description
Technical Field
[0001] This utility model relates to the field of tablet computer protective case technology, specifically to the field of tablet computer protective case stand opening and flip detection. Background Technology
[0002] Tablet cases typically include a stand to prop up the tablet, which folds back into the case when not in use. Currently, the stand and case are magnetically attached, and the strength of this attachment significantly impacts the user experience. Therefore, after production, the opening force of the stand and case needs to be tested—that is, measuring the magnetic force between the magnets. Additionally, since the case connects to the stand via a hinge, the torque during stand rotation also needs to be tested. Currently, stand opening and flipping tests are primarily manual, relying on operators to manually open and flip the stand. This method is highly susceptible to human error, affecting product consistency, and different operators may yield different results. Summary of the Invention
[0003] The purpose of this invention is to provide a two-in-one testing machine for opening and flipping the stand of a tablet computer protective case. The machine replaces manual opening and flipping of the stand, reducing the impact of human error, and can feed the test results back to the production end for production control, thereby ensuring product quality.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A two-in-one testing machine for opening and flipping the stand of a tablet computer case, which features:
[0006] The base, on which a control system for testing is assembled, and a worktable is provided at the upper end of the base, which is adapted to be laid flat with a tablet computer protective cover;
[0007] A clamping mechanism is installed on the aforementioned base. The clamping mechanism is used to clamp the tablet computer protective cover placed on the worktable.
[0008] The testing mechanism is mounted on the aforementioned base and includes a pull rod that is vertically positioned above the workbench. The lower end of the pull rod has a hook that is adapted to attach the bracket of the tablet computer protective case. The upper end of the pull rod is connected to a lifting device via a force sensor. The lifting device raises the pull rod, causing it to move upwards and thus pull the bracket open via the hook. The force sensor records the opening force value of the bracket and outputs it to the control system.
[0009] The lifter is mounted on the flip bracket, which is assembled on the base and can rotate relative to it. The lifter is driven to rotate by the flip bracket, which in turn drives the pull rod to rotate the bracket relative to the tablet computer protective case. The force sensor records the torque during the rotation of the bracket and outputs it to the control system, achieving a two-in-one detection of bracket opening and flipping.
[0010] The above solution is further provided with a protective cover at the upper end of the base, which covers the workbench, the clamping mechanism and the testing mechanism, and the front of the protective cover is provided with an opening and closing door and a safety light curtain switch.
[0011] The above solution further includes a pressure plate, lifting guide columns, and a cylinder. There are two lifting guide columns symmetrically distributed on both sides of the worktable. The two lifting guide columns are mounted on the machine base through bushings and are set vertically. The upper ends of the two lifting guide columns are connected to the pressure plate, so that the pressure plate is horizontally placed on the upper side of the worktable. The lower ends of the two lifting guide columns are connected to the cylinder. The cylinder extends and retracts to drive the two lifting guide columns to move up and down synchronously, so that the pressure plate can descend and press the tablet computer protective cover placed on the worktable.
[0012] The above-mentioned solution is further described as follows: the tilting bracket includes a crossbeam, a swing arm, and a servo motor; there are two swing arms symmetrically distributed on both sides of the worktable, and the lower ends of the two swing arms are respectively mounted on the machine base through a rotating shaft, allowing the swing arms to rotate relative to the machine base. One of the swing arms is also connected to the servo motor through the rotating shaft, and the servo motor drives the swing arm to tilt; the upper ends of the two swing arms are connected together to the crossbeam, and the crossbeam connects the two swing arms in a linkage relationship; the crossbeam is horizontally arranged on the upper side of the worktable, and the lifting device is installed on the crossbeam.
[0013] A further improvement in the above scheme is that the lifting device is a motor lead screw structure, and the extension end of the lead screw is connected to a force sensor.
[0014] By adopting the above structure, the present invention achieves the following beneficial effects:
[0015] 1. The lifting device drives the pull rod upward, thereby pulling the bracket on the tablet case and opening it against the magnetic attraction. The force sensor records the opening force of the bracket and outputs it to the control system. The lifting device is installed on the flip bracket. The flip bracket drives the lifting device to rotate, which in turn causes the pull rod to rotate the bracket relative to the tablet case. The force sensor records the torque during the rotation of the bracket and outputs it to the control system, achieving a two-in-one detection of bracket opening and flipping.
[0016] 2. The clamping mechanism allows for the rapid pressing of tablet computer cases onto the worktable for testing. The structure is simple and can be adapted to test tablet computer cases of different sizes, thus increasing its applicability.
[0017] 3. This utility model can improve the testing accuracy of bracket opening and flipping, and can realize the feedback of the test results to the production end, thereby controlling the production and ensuring product quality. Attached Figure Description

[0022] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.
[0023] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0024] See Figure 1 , 2 Figures 3 and 4 show schematic diagrams of a preferred embodiment of this utility model. This utility model relates to a two-in-one testing machine for opening and flipping a tablet computer case support. It includes: a base 1, a clamping mechanism 2, and a testing mechanism 3. A control system for testing is assembled on the base 1. The control system is a common mechanical motion control system that outputs corresponding data to the production line. A worktable 11 is provided at the upper end of the base. This worktable is adapted to accommodate a tablet computer case 100 placed flat. The tablet computer case 100 has a support 103, which is connected to the tablet computer case via a hinge 102 to achieve opening and closing movement. The movable end of the support is magnetically attracted to the tablet computer case to achieve folding.
[0025] A clamping mechanism 2 is mounted on the base 1 and is used to clamp the tablet computer protective cover placed on the worktable. In this embodiment, the clamping mechanism 2 includes a pressure plate 21, lifting guide columns 22, and a cylinder 23. Two lifting guide columns 22 are symmetrically distributed on both sides of the worktable 11. The two lifting guide columns 22 are mounted on the base via bushings and are erected vertically. The upper ends of the two lifting guide columns 22 are connected to the pressure plate 21, so that the pressure plate 21 is horizontally positioned on the upper side of the worktable 11. The lower ends of the two lifting guide columns 22 are connected to the cylinder 23, and the cylinder 23 extends and retracts to drive the two lifting guide columns 22 to move synchronously up and down. In this embodiment, the lower ends of the two lifting guide columns 22 are connected together by a connecting rod, and the middle section of the connecting rod is connected to the telescopic end of the cylinder 23. Thus, the cylinder 23 can drive the two lifting guide columns 22 to move synchronously up and down via the connecting rod. When the two lifting guide columns 22 move upward, they lift the pressure plate 21, moving it away from the worktable 11, allowing the tablet computer protective case 100 to be placed or removed. When the two lifting guide columns 22 move downward, they pull down the pressure plate 21, causing it to press down on the tablet computer protective case placed on the worktable, thus securing it. The structure is simple and easy to operate. Figure 3 As shown, in this preferred embodiment, the pressing direction of the pressure plate 21 is consistent with the design direction of the hinge 102 on the tablet computer protective case, and the pressure plate 21 avoids interfering with the flip test of the bracket 103.
[0026] The testing mechanism 3 is mounted on the aforementioned base 1, and the testing mechanism 3 is equipped with a pull rod 31, which is vertically mounted above the workbench 11. The lower end of the pull rod 31 is equipped with a hook 311, which is adapted to fasten the bracket of the tablet computer protective case. For example... Figure 4As shown, in this embodiment, the hook 311 is structurally adapted to fit into the pre-set slot 101 of the tablet computer protective case. This slot is designed to facilitate the movement of the bracket 103. The hook 311 also has an appropriate structure for fastening the bracket, such as teeth or grooves, to better pick up the bracket. The upper end of the pull rod 31 is connected to the lifter 33 via a force sensor 32, which is electrically connected to the control system on the base 1. The lifter 33 lifts the pull rod 31 upward, thereby pulling the bracket open via the hook. The force sensor 32 records the opening force value of the bracket and outputs it to the control system, realizing mechanical replacement of manual detection. The lifter 33 is also mounted on the flip bracket 34, which is assembled on the base 1 and can rotate relative to it. The flip bracket 34 drives the lifter 33 to rotate, thereby enabling the pull rod 31 to drive the bracket to rotate relative to the tablet computer protective case. The force sensor 32 records the torque during the rotation of the bracket and outputs it to the control system. Through the above structural design, continuous detection of the bracket's opening and rotation is achieved, realizing a two-in-one detection function for bracket opening and rotation, thus improving the usability and economy of the testing machine. In this embodiment, the lifting device 33 is preferably a motor lead screw structure, with the extension end of the lead screw connected to the force sensor 32. This design is simple in structure, compact in size, and easy to control.
[0027] Figure 1 , 2 As shown in Figure 3, in this embodiment, the upper end of the base is provided with a protective cover 12, which covers the workbench 11, the clamping mechanism 2 and the testing mechanism 3. The front of the protective cover 12 is provided with an opening and closing door and a safety light curtain switch. This structural design can provide a good testing environment and improve the safety of use.
[0028] Figure 1 , 2 As shown in Figure 3, in this embodiment, the flipping support 34 includes a crossbeam 341, a swing arm 342, and a servo motor 343. Two swing arms 342 are symmetrically distributed on both sides of the worktable 11. The lower ends of the two swing arms are respectively mounted on the machine base via rotating shafts, allowing the swing arms to rotate relative to the machine base. One of the swing arms is also connected to the servo motor 343 via a rotating shaft, driving the swing arm to flip. The upper ends of the two swing arms are connected together to the crossbeam 341, which links the two swing arms in a linkage relationship. The crossbeam 341 is horizontally positioned on the upper side of the worktable 11, and a lifter 33 is mounted on the crossbeam 341. After detecting the opening force of the support, the lifter 33 stops lifting, and the servo motor 343 outputs power, driving the crossbeam to flip through the two swing arms. At this time, the lifter 33, in conjunction with the pull rod, drives the support to rotate. During the rotation, a force sensor records the torque magnitude of the support during rotation and transmits it to the control system, obtaining the support flipping detection result.
[0029] This invention utilizes a lifting mechanism to move a pull rod upwards, thereby pulling the bracket on the tablet case and causing it to open against magnetic attraction. A force sensor records the opening force and outputs it to the control system. The lifting mechanism is mounted on a flip-up bracket, which rotates the lifting mechanism, causing the pull rod to rotate the bracket relative to the tablet case. The force sensor records the torque during the rotation and outputs it to the control system, achieving a combined detection of bracket opening and flipping. A clamping mechanism allows for quick pressing of the tablet case onto a worktable for testing. The simple structure is adaptable to tablet cases of different sizes, increasing its applicability. This invention not only replaces manual inspection with mechanical methods, improving the accuracy of bracket opening and flipping tests, but also allows for feedback of the test results to the production end, enabling production control and ensuring product quality.
[0030] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
