Description

Technical Field

[0001] This utility model relates to the field of tablet computer quality inspection technology, and in particular to a side magnetic force detection device for tablet computers. Background Technology

[0002] In the design and production of tablet computers, the performance of the side magnetic force is a key indicator affecting the user experience, directly impacting the connection stability and ease of use of accessories such as external keyboards and protective cases. Therefore, accurate and reliable testing of the tablet computer's side magnetic force is a crucial step in ensuring product quality.

[0003] Currently, the industry commonly uses manual push-pull force gauges for magnetic force testing, but this method has significant technical limitations. Firstly, during manual operation, it's difficult for the tester to maintain a stable direction and speed of the pulling force, causing violent shaking during the separation of the tablet and the testing end. This not only easily leads to instantaneous peak deviations in the test data but also results in large dispersion in multiple tests of the same product, making it impossible to establish a unified quality assessment standard and severely impacting testing efficiency and accuracy. Secondly, in existing testing solutions, the push-pull force gauge and the magnetic attraction structure on the side of the tablet are rigidly fixed. Since dimensional tolerances (such as side flatness deviations and length errors) are unavoidable in the tablet casing during injection molding and assembly processes, when the actual product size deviates from the standard value, the rigidly connected testing end cannot adaptively adjust its position, resulting in loose or even completely misaligned magnetic surfaces. In this situation, the testing device cannot effectively attract the product or transmit accurate magnetic force values, easily leading to misjudgments of qualified products or missed detection of defective products, causing quality risks and cost losses for manufacturers.

[0004] With consumers demanding higher quality electronic products and smart manufacturing requiring greater precision in testing, existing testing methods are no longer sufficient to meet the quality control needs of large-scale production. Developing a magnetic testing device that can achieve stable separation, ensure test consistency, and adapt to product dimensional deviations has become an urgent need to overcome current technological bottlenecks.

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] This utility model discloses a side magnetic force detection device for a tablet computer, such as... Figures 1-9As shown, the system includes: a controller, an operating console 100, a control component 200, a fixing component 300, and a testing component 400. The controller is located inside the operating console 100. The control component 200 is located on the front side of the operating console 100, i.e., the side of the operating console 100 facing the operator. The control component 200 includes a control panel 210, which has several buttons 211 and indicator lights 212. In this embodiment, the buttons 211 include two start buttons 2112 connected in series and an emergency stop button 2111. The indicator lights 212 include a PASS light 2121 and a FAIL light 2122. The buttons 211 and indicator lights 212 are all electrically connected to the controller. The fixing component 300 includes: a product placement position 300a disposed on the upper surface of the operating table 100, a pressure plate 310 movably disposed above the product placement position 300a, and a cylinder 320. The pressure plate 310 is fixedly connected to the telescopic shaft of the cylinder 320. The cylinder 320 is connected to an external air source, which provides power to the cylinder 320, causing the telescopic shaft of the cylinder 320 to extend and retract, driving the pressure plate 310 to move up and down in the vertical direction. During testing, the pressure plate 310 presses on the tablet computer placed in the product placement position 300a, serving a fixing function. The number of cylinders 320 is determined according to actual needs. In this embodiment, there are two cylinders 320, which are respectively disposed on the left and right sides of the product placement position 300a. The two cylinders 320 can apply a uniform driving force to the pressure plate 310 to avoid jamming.The test assembly 400 includes: a sliding table 410 slidably disposed on the upper surface of the operating table 100; a push-pull force gauge 420 fixed on the sliding table 410; a flexible clamping unit 430 slidably disposed on the upper surface of the operating table 100; and a motor disposed within the operating table 100 and pulsatorically connected to the sliding table 410. A protrusion 421 is fixed to the tip of the probe of the push-pull force gauge 420. The flexible clamping unit 430 forms a first receiving cavity 430a on the side facing the push-pull force gauge 420 to accommodate the protrusion 421 and has a first through hole 430b facing the push-pull force gauge 420. A stop 431 is provided at the first through hole 430b to restrict the protrusion 421 from moving out of the first receiving cavity 430a. The protrusion 421 is provided with… Within the first receiving cavity 430a, the flexible clamping unit 430 can move back and forth. When the protrusion 421 moves forward and abuts against the wall of the first receiving cavity 430a, its continued movement pushes the flexible clamping unit 430 forward, bringing it closer to the product placement position 300a. When the protrusion 421 moves backward and abuts against the stop 431 on the first through hole 430b of the first receiving cavity 430a, its continued movement pulls the flexible clamping unit 430 backward, moving it away from the product placement position 300a. The flexible clamping unit 430, facing the product placement position 300a, holds the test pen 432. The test pen 432's shape and internal magnetic device are similar to a stylus and external keyboard used with a tablet computer. The device is manufactured to standard specifications to simulate real-world usage scenarios. The test pen 432 can also be directly used with the stylus that comes with the tablet computer. The motor drives the sliding stage 410 to move the push-pull force gauge 420 back and forth, thereby moving the flexible clamping unit 430 and the test pen 432 on it closer to or further away from the tablet computer at the product placement position 300a. The motor, push-pull force gauge 420, and controller are electrically connected. The flexible clamping unit 430 includes a fixing part 433 and a clamping part 434 for clamping the test pen. The fixing part 433 and the clamping part 434 are movably connected by an equal-height bolt 435. The fixing part 433 forms a second receiving cavity 433a. The fixing part 433 has an opening facing the clamping part 434 that connects to the second receiving cavity. The cavity 433a is connected to the second through hole 433b. The head of the equalizing bolt 435 is movably disposed in the second receiving cavity 433a. The bolt of the equalizing bolt 435 slides out from the second through hole 433b. The threaded part of the equalizing bolt 435 is threadedly connected to the clamping part 434, that is, the equalizing bolt 435 and the clamping part 434 form a whole. This whole can move back and forth in the horizontal direction. A spring 436 is also sleeved on the bolt, with its two ends connected to the fixing part 433 and the clamping part 434 respectively. The spring 436 is used to reduce the instantaneous change of the push-pull force value when the test pen 432 is attracted or separated from the product. The flexible clamping unit 430 as a whole can adaptively compensate for the size deviation between the tablet computer and the test pen 432.

[0033] The operation process of the side magnetic force detection device for tablet computers provided by this utility model is as follows: Step S1, place the tablet computer to be tested in the product placement position 300a; Step S2, the operator presses both start buttons 2112 simultaneously; Step S3, the cylinder 320 drives the pressure plate 310 to move downwards and finally presses it onto the tablet computer to be tested, at which point the tablet computer is fixed and cannot move; Step S4, the push-pull force gauge 420 pushes the flexible clamping unit 430 to move towards the product placement position 300a, at which point the push-pull force gauge 420 pushes the flexible clamping unit 430 to move towards the product placement position 300a. The protrusion 421 on the probe of the force gauge 420 presses against the cavity wall of the first receiving cavity 430a of the flexible clamping unit 430 near the product placement position 300a (defined as the front wall). The movement continues until the distance between the test pen 432 held by the flexible clamping unit 430 and the tablet computer under test (defined as distance A) is less than the distance between the protrusion 421 on the probe of the push-pull force gauge 420 and the stop block 431 on the first through hole 430b of the first receiving cavity 430a (defined as distance B). The sliding stage 410 then stops moving. Figure 7 As shown; in step S5, the test pen 432 is used to magnetically attract the tablet computer, while simultaneously driving the flexible clamping unit 430 to continue moving forward. At this time, the protrusion 421 separates from the front wall and is located in the middle of the first receiving cavity 430a, as shown. Figure 8 As shown, distance A is zero, and a zeroing operation is performed on the push-pull force gauge 420; in step S6, the push-pull force gauge 420 moves backward, and the protrusion 421 moves backward to engage with the stop block 431. The protrusion 421 continues to move backward, as shown... Figure 9 As shown, the push-pull force gauge 420 starts to display the pulling force until the test pen 432 separates from the tablet computer, records the peak pulling force, and transmits the peak pulling force to the controller; Step S7: Compare the peak pulling force with the preset range (or preset value) of the magnetic force. If the test is qualified, the PASS light 2121 lights up; if the test is unqualified, the FAIL light 2122 lights up; Step S8: The test ends and the tablet computer is removed.

[0034] The side magnetic force detection device for tablet computers provided by this utility model uses a motor-driven sliding stage to move a push-pull force gauge 420, realizing automated control of the testing process, ensuring consistent pulling force direction and stable speed, and avoiding violent shaking during separation. Simultaneously, symmetrical cylinders 320 drive a pressure plate 310 to fix the tablet computer, reducing displacement interference during testing. Combined with the push-pull force gauge 420, it accurately records peak pulling force, reducing instantaneous data deviation and the dispersion of multiple tests, forming a unified quality evaluation standard, and improving testing efficiency and accuracy. Furthermore, the flexible clamping unit 430 of this device is movably connected to a spring 436 via equal-height bolts 435. The fixing part 433 and the clamping part 434 can be relatively horizontally fine-tuned, allowing the testing pen 432 to adapt to dimensional deviations on the side of the tablet computer (such as flatness and length errors), ensuring a tight fit of the magnetic surface, avoiding attraction failure or force transmission distortion caused by misalignment, thereby reducing misjudgment of qualified products or missed detection of defective products, and lowering quality risks and cost losses.

[0035] In one embodiment, such as Figure 1 , Figure 2 As shown, a pressure regulating valve 330 (connecting pipe not shown) is installed on the pipe connecting the cylinder 320 to the external air source. The pressure regulating valve 330 precisely controls the driving force of the cylinder 320 on the pressure plate 310 by adjusting the gas pressure entering the cylinder 320, thereby flexibly adjusting the clamping force of the pressure plate 310 on the tablet computer. The pressure regulating valve 330 can adaptively adjust the pressure according to the differences in shell material, thickness and structural strength of different tablet computer models. This avoids excessive pressure that may cause product deformation or scratches, and also prevents insufficient pressure that may cause the tablet to shake during testing, thereby enhancing test stability and reducing data deviation. At the same time, the same device can be adapted to multiple product specifications without frequent adjustments to the mechanical structure, improving versatility and ease of operation, and reducing equipment modification costs.

[0036] In one embodiment, such as Figure 1 , Figure 2As shown, a housing 500 is added above the fixed component 300. The housing 500 is fixed to the upper surface of the operating table 100 by its support plate. The side wall of the housing 500 has a material feeding port 500a and a test port 500b, and a barcode scanner 510 is also configured thereon. By adding the housing 500, a relatively enclosed test space is formed, reducing interference from the external environment. The barcode scanner 510 is used to automatically identify the model, batch, and other information of the tablet computer under test and transmit it to the controller, realizing the association between product information and test data. The housing 500 can prevent dust and foreign object intrusion, protect the test components and products, and reduce interference from external disturbances on the test process, thereby improving test stability. The barcode scanner 510 replaces manual input of product information, improves operational efficiency, avoids information input errors, and can automatically match the magnetic preset parameters of the corresponding product to achieve intelligent testing. In addition, the housing 500 can also isolate moving parts in the test area, improving operational safety. The design of the material feeding port 500a and the test port 500b ensures smooth product loading and unloading and testing actions.

[0037] In one embodiment, such as Figure 1 As shown, a grating 520 electrically connected to the controller is installed at the discharge port 500a. Utilizing the light signal sensing characteristics of the grating 520, it monitors in real time whether foreign objects (such as the operator's hand, tools, etc.) enter the housing 500 in the area of ​​the discharge port 500a. When a foreign object is detected, the grating 520 transmits a signal to the controller, which immediately triggers the equipment to pause or stop operation. This forms a safety barrier without affecting the normal handling of tablet computers, preventing operators from accidentally putting their hands into the housing 500 and coming into contact with moving test components 400 (such as the sliding table 410, flexible clamping unit 430) during equipment operation, thus significantly improving operational safety. At the same time, compared with traditional mechanical protection, the grating 420 responds more quickly, can accurately identify small foreign objects, and does not obstruct the operator's line of sight, ensuring the smoothness of the testing process and reducing the risk of safety accidents.

[0038] In one embodiment, such as Figure 1 , Figure 2As shown, a guide post 530 extending vertically is sandwiched between the top plate of the outer shell 500 and the upper surface of the operating table 100. A third through hole matching the guide post 530 is opened on the pressure plate 310. The pressure plate 310 is sleeved on the guide post 530 through the third through hole. The cooperation between the guide post 530 and the third through hole provides rigid guiding constraint for the up and down movement of the pressure plate 310, limiting its horizontal deviation or tilting. This can prevent the pressure plate 310 from tilting due to the difference in synchronization of the cylinder 320, ensuring that it presses the tablet computer evenly, preventing product damage or displacement, ensuring the relative position of the tablet computer and the test pen 432 is stable to improve the detection accuracy, while reducing the mechanical wear of the cylinder 320 caused by radial force, extending the equipment life, and preventing the pressure plate 310 from colliding with other components, enhancing operational safety, and also improving the adaptability to products of different specifications.

[0039] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 As shown, a positioning block 340 protrudes from the product placement position 300a and fits against the edge of the tablet computer. The physical fit between the positioning block 340 and the edge of the tablet computer provides precise horizontal positioning for the tablet computer, ensuring that the tablet computer can be quickly and accurately positioned in the preset test position when placed in the product placement position 300a. This avoids deviations in the relative position of the tablet computer's side and the test pen 432 due to placement offset. On the one hand, this simplifies the material placement operation for operators, eliminating the need to repeatedly adjust the tablet computer's position and improving operational efficiency. On the other hand, it ensures the alignment accuracy of the tablet computer's side and the test pen 432 during each test, avoiding magnetic force detection deviations caused by inconsistent placement positions (such as the deviation of the attraction position between the test pen 432 and the tablet computer affecting the accuracy of the peak tensile force). This reduces the dispersion of results from multiple tests of the same product, enhances the reliability of the test data, and also works with the pressure plate 310 to more stably fix the tablet computer, further improving the stability of the testing process.

[0040] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a slide rail 440 is added between the flexible clamping unit 430 and the upper surface of the operating table 100, so that the flexible clamping unit 430 is slidably mounted on the slide rail 440. The principle is to use the guiding effect of the slide rail 440 to provide a precise and stable motion trajectory for the forward and backward movement of the flexible clamping unit 430, restricting the horizontal offset or wobbling of the flexible clamping unit 430, and ensuring that it can only move smoothly along the direction of the slide rail 440. The advantage of this improvement is that it can significantly improve the linearity and stability of the movement of the flexible clamping unit 430 and the test pen 432, and avoid the problems caused by unevenness of the upper surface of the operating table 100 or the flexible clamping unit 430. The zero-weight-shift mechanism prevents movement jamming and deviation, ensuring the precise relative position of the test pen 432 and the side of the tablet computer, reducing data fluctuations in the push-pull force gauge 420 caused by unstable movement. Simultaneously, the slide rail 440 reduces friction during the movement of the flexible clamping unit 430, making the driving force transmitted by the push-pull force gauge 420 more stable, avoiding interference from additional resistance on peak tension measurement, improving the accuracy of the test data, and reducing mechanical wear between the flexible clamping unit 430 and the operating table 100, extending the equipment's lifespan. Combined with other structures in the test assembly 400, this further enhances the reliability of the entire testing process.

[0041] The aforementioned side magnetic force detection device for tablet computers achieves automated testing by using a motor-driven sliding stage to move a push-pull force gauge, ensuring consistent pulling force direction and stable speed. Combined with a cylinder-driven pressure plate to fix the tablet computer, it reduces product displacement interference, lowers data deviation and test dispersion, and improves testing efficiency and accuracy. Simultaneously, the flexible clamping unit, through the relative position design of the first receiving cavity and the protrusion on the push-pull force gauge probe, and the movable connection between the fixing and clamping parts of the flexible clamping unit via equal-height bolts and springs, along with the use of a test pen compatible with the tablet computer's accessories, can adapt to the dimensional tolerances of the tablet computer's side, ensuring a tight fit of the magnetic surface and avoiding misjudgments or missed detections due to misalignment. It also effectively reduces severe shaking during testing. All of the above measures reduce the quality risks and cost losses associated with side magnetic force detection of tablet computers.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
