Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, and in particular to a pressure-holding box inspection device and its usage method. Background Technology

[0002] In the assembly process of electronic products, pressure-holding fixtures are devices used to assist in maintaining pressure on the product. For example, the mid-frame pressure-holding box is such a pressure-holding fixture, which is used to perform time-curing treatment of the adhesive after the mid-frame of the mobile phone is bonded to the screen.

[0003] As a reusable product, pressure-holding boxes require regular inspection to ensure accuracy during subsequent pressure-holding operations and prevent deformation. Most existing pressure-holding box inspection equipment tests the pressure holding rate; boxes with abnormal pressure are deemed unqualified. However, in reality, multiple components on the pressure-holding box affect the pressure-holding effect. For example, the magnet's adhesion stability affects the pressure-holding effect; a silicone head that is too soft will not achieve the desired pressure-holding effect, while one that is too hard may damage the product; the surface flatness of the pressure-holding box directly affects its sealing performance, stability, and fit with compatible components, thus impacting the pressure-holding effect. Therefore, simply testing the pressure holding rate to determine if the box meets the pressure-holding requirements is inaccurate. Furthermore, scrapping the entire pressure-holding box due to a failed pressure holding rate increases production costs and is wasteful. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automated pressure box inspection device that can inspect multiple components and multiple points of the pressure box to improve the efficiency and accuracy of inspection, avoid waste and reduce production costs.

[0005] The objective of this invention is achieved through the following technical solution: A pressure-holding box inspection device, comprising: The machine base is provided with an equipment fixing plate and a testing platform base. The equipment fixing plate is fixed on the machine base, and the testing platform base is connected to the equipment fixing plate. A product profiling block is placed on the testing platform base. A clamping and lifting mechanism is connected to the bottom of the machine base. The clamping and lifting mechanism clamps the pressure holding box and moves it up and down relative to the detection platform base. The pressure holding box is equipped with a magnet and a silicone pressure head. When the clamping and lifting mechanism descends to the bottom position, it places the pressure holding box on the detection platform base, and the silicone pressure head presses against the product molding block. The testing mechanism includes a magnet testing component, a flatness testing component, a silicone hardness testing component, and a pressure testing component. The magnet testing component is located behind the clamping and lifting mechanism and can be pushed horizontally above the pressure-holding box clamped by the clamping and lifting mechanism to test the Gauss value of the magnet. The flatness testing component is connected to the equipment mounting plate, passes through the testing platform base, and contacts the pressure-holding box placed on the testing platform base to test its flatness. The silicone hardness testing component is connected to the equipment mounting plate, passes through the product molding block, and contacts the silicone indenter to test its hardness. The pressure testing component is connected between the product molding block and the equipment mounting plate to detect the pressure value applied to the product molding block. An operating system is provided, which is electrically connected to the lifting mechanism and the detection mechanism.

[0006] In a preferred embodiment, the surface of the testing platform base facing the pressure holding box is provided with a positioning protrusion and a magnetic connector. When the pressure holding box is placed on the testing platform base, the positioning protrusion positions the pressure holding box, and the magnetic connector is magnetically connected to the magnet.

[0007] In a preferred embodiment, the gripping and lifting mechanism includes grippers and a lifting assembly. The grippers are positioned on the left and right sides above the detection platform base and are used to hold the pressure-holding box. The lifting assembly includes a drive cylinder, a lifting connecting plate, and several lifting guide rods. The fixed end of the drive cylinder is located at the bottom of the machine base, and the telescopic end of the drive cylinder is connected to the lifting connecting plate. One end of each lifting guide rod is connected to the lifting connecting plate, and the other end of each lifting guide rod passes through the equipment fixing plate and is detachably connected to the grippers.

[0008] In a preferred embodiment, the clamping and lifting mechanism further includes a buffer and a buffer guide post. The buffer is connected to the lifting connecting plate, and the buffer guide post is disposed at the bottom of the machine platform at a position corresponding to the buffer.

[0009] In a preferred embodiment, the detection mechanism further includes a detection grating and a detection laser. The detection grating is disposed on the outside of the gripper facing away from the detection platform base, and the detection grating is used to detect whether a pressure holding box is placed on the gripper. The detection laser is disposed on the equipment fixing plate, and the detection laser is used to detect whether a pressure holding box is placed on the platform base.

[0010] In a preferred embodiment, the magnet detection assembly includes a magnetic field detection fixing plate, a push cylinder, and a push guide rod. The push cylinder is mounted on the machine base and connected to the push guide rod. The push guide rod is connected to the magnetic field detection fixing plate. A magnetic field strength detection needle is mounted on the magnetic field detection fixing plate. The push cylinder drives the push guide rod to push the magnetic field detection fixing plate out and retract. The magnetic field strength detection needle is used to detect the Gauss value of the magnet.

[0011] In a preferred embodiment, the flatness detection component includes several displacement gratings and several flatness detection heads. The displacement gratings are mounted on the equipment fixing plate, and each flatness detection head is connected to a corresponding displacement grating. The flatness detection head passes through the detection platform base and contacts the pressure holding box placed on the detection platform base. The displacement gratings measure the displacement of the flatness detection head.

[0012] In a preferred embodiment, the silicone hardness testing component includes a hardness tester and a hardness testing probe. The hardness tester is fixed on the equipment mounting plate and connected to the hardness testing probe. The hardness testing probe passes through the product molding block and contacts the silicone indenter.

[0013] In a preferred embodiment, the pressure detection component includes a pressure fixing block and a pressure sensor. The pressure fixing block is connected to the product molding block, and the pressure sensor is connected between the pressure fixing block and the base plate.

[0014] The method of using the above-mentioned pressure-holding box inspection equipment includes the following steps: S1. Place the pressure-holding box into the clamping and lifting mechanism, and the equipment starts testing; S2 Magnet Detection: The magnet detection component is pushed out above the pressure box. The magnet detection component detects the Gauss value of the magnet on the pressure box. The control system determines whether the Gauss value meets the set range. After the detection is completed, the magnet detection component is retracted, the lifting mechanism descends, and the pressure box is placed on the detection platform base. S3 Flatness Detection: After the pressure holding box is placed on the detection platform base, the contact surface between the pressure holding box and the detection platform base and the flatness detection component are in contact to perform flatness detection. The control system determines whether the flatness of the entire contact surface meets the set range based on the detection value of the flatness detection component. S4 Silicone Hardness Testing: After the pressure box is placed on the testing platform, the silicone indenter presses against the product molding block. The silicone hardness testing component contacts the silicone indenter to perform hardness testing. The control system determines whether the silicone hardness meets the set range based on the test value of the silicone hardness component. S5 Pressure Detection: After the pressure holding box is placed on the detection platform, the pressure detection component detects the pressure value as the product molding block is pressed, and the control system determines whether the pressure value is within the acceptable range. S6 Based on the test results of S2-S5, if all four test results are within the set range, the test is passed, and the pressure box is removed for later use; if any one of the four test results is outside the set range, the test fails, the pressure box is removed, and the test results are classified, stored, and processed accordingly.

[0015] Compared with the prior art, the present invention has at least the following advantages: 1. The pressure-holding box inspection equipment of the present invention integrates a magnet detection component, a flatness detection component, a silicone hardness detection component, and a pressure detection component to detect the magnet strength, flatness, silicone indenter, and pressure of the pressure-holding box. This enables multi-part, multi-point inspection of the pressure-holding box. Pressure-holding boxes that meet the requirements of all four tests are deemed qualified, improving the efficiency and accuracy of the inspection. Based on the results of the four tests, unqualified items of the pressure-holding box can be classified, providing a basis for decision-making regarding subsequent maintenance, adjustment, reuse, or scrapping of the pressure-holding box, thus avoiding waste.

[0016] 2. The pressure box inspection equipment of the present invention, through the cooperation of the gripper and the lifting component, makes the equipment suitable for the inspection of pressure boxes of different sizes and specifications. Attached Figure Description

[0021] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0022] See Figure 1 , Figure 2 The pressure-holding box inspection equipment includes a machine base 100, a clamping and lifting mechanism 200, an inspection mechanism 400, and an operating system 500. The machine base 100 is equipped with a machine fixing plate 110 and an inspection platform base 120. The machine fixing plate 110 is fixed to the machine base 100, and the inspection platform base 120 is connected to the machine fixing plate 110. A product profiling block 121 is placed on the inspection platform base 120. The clamping and lifting mechanism 200 is connected to the bottom of the machine base 100. The clamping and lifting mechanism 200 clamps the pressure-holding box 300 and moves it up and down relative to the inspection platform base 120. Figure 7The pressure-holding box 300 is equipped with a magnet 310 and a silicone pressure head 320. When the clamping and lifting mechanism 200 descends to its position, the pressure-holding box 300 is placed on the testing platform base 120, and the silicone pressure head 320 presses against the product molding block 121. The testing mechanism 400 includes a magnet 310 testing component 410, a flatness testing component 420, a silicone hardness testing component 430, and a pressure testing component 440. The magnet 310 testing component 410 is located behind the clamping and lifting mechanism 200 and can be pushed horizontally above the pressure-holding box 300 clamped by the clamping and lifting mechanism 200 to test the Gauss value of the magnet 310. The flatness testing component 420 is connected to the equipment fixing plate 110. A flatness detection component 420 passes through the detection platform base 120 and contacts the pressure holding box 300 placed on the detection platform base 120 to detect the flatness of the pressure holding box 300; a silicone hardness detection component 430 is connected to the equipment fixing plate 110 and passes through the product molding block 121, contacting the silicone indenter 320 to detect the hardness of the silicone indenter 320; a pressure detection component 440 is connected between the product molding block 121 and the equipment fixing plate 110, and is used to detect the pressure value of the product molding block 121; an operating system 500 is electrically connected to the lifting mechanism and the detection mechanism 400.

[0023] It should be noted that the machine base 100 serves as the main support for the entire equipment, with a fixed plate 110 mounted on it as a fixed platform. The testing platform base 120 is connected to the fixed plate 110 to provide a reference for the testing of the pressure box 300. The clamping and lifting mechanism 200 can clamp the pressure box 300 and move up and down relative to the testing platform base 120, thus clamping and moving the pressure box 300 up and down. When the clamping and lifting mechanism 200 with the pressure box 300 descends to the preset position, it accurately places the pressure box 300 on the testing platform base 120, causing the silicone pressure head 320 to press against the product molding block 121. The magnet 310 testing component 410 is located behind the clamping and lifting mechanism 200 and has a horizontal pushing function. Yes, once the pressure box 300 is placed on the clamping and lifting mechanism 200 at a suitable position, the magnet 310 detection component 410 is pushed horizontally above the pressure box 300 held by the clamping and lifting mechanism 200 to detect the Gauss value of the magnet 310 on the pressure box 300. Through the measurement of the Gauss value, the control system can determine the polarity of the magnet 310 (whether it is installed backwards or damaged) and whether it is missing. For example, if the polarity is reversed, the Gauss value will be opposite to the sign of the set range (if the set value is positive, the reversed value will be negative). If the polarity is damaged, the Gauss value will decrease. If it is missing, no Gauss value can be measured, thus determining whether the magnetism of the magnet 310 meets the requirements. The flatness detection component 420 is connected to the equipment fixing plate 110 and passes through the detection platform. When the pressure box 300 is placed on the testing platform 120, the flatness detection component 420 contacts the surface of the pressure box 300 to perform flatness detection. It can be understood that the flatness detection component 420 can use contact or non-contact sensors to measure displacement. Multiple contact points can be set between the flatness detection component 420 and the pressure box 300, allowing it to measure the position information at different points. The control system calculates the displacement based on the measured position information and compares it with the corresponding set displacement for each point to determine whether the flatness of the pressure box 300 meets the standard. The silicone hardness detection component 430 is connected to the equipment fixing plate 110 and passes through... When the pressure box 300 is placed and the silicone indenter 320 presses against the product molding block 121, the silicone hardness detection component 430 contacts the silicone indenter 320 to detect its hardness. The control system determines whether the hardness of the silicone indenter 320 meets the set range based on the detected value. When the silicone indenter 320 presses against the product molding block 121, the pressure applied by the pressure box 300 is transmitted to the product molding block 121. The pressure signal is then converted into an electrical signal by the pressure detection component 440. The operating system 500 receives and processes these electrical signals to obtain the pressure value of the product molding block 121, thereby determining whether the pressure applied by the pressure box 300 is within a reasonable range.The operating system 500 centrally controls and processes data throughout the entire testing process. The operating system 500 can control the rising and falling movements of the clamping lifting mechanism 200, precisely controlling its position and speed. Simultaneously, the operating system 500 receives testing data from the magnet 310 detection component 410, the flatness detection component 420, the silicone hardness detection component 430, and the pressure detection component 440. It stores, analyzes, and processes this data, and determines whether the performance of the pressure holding box 300 is qualified based on preset standard values. Finally, it provides the test results, such as... Figure 1 The operating system 500 includes a display screen. The Gauss value of the magnet 310, the flatness of the pressure box 300, the hardness of the silicone indenter 320, and the pressure value of the product molding block 121 detected by the testing mechanism 400 during the testing process are displayed on the display screen. The operating system 500 can indicate whether the pressure box 300 has passed based on the results of the above four tests, so that the operator can proceed to the next step.

[0024] During the testing process, each testing component is tested based on a specific position of the pressure holding box 300. If the position of the pressure holding box 300 is offset, the testing component may not be able to accurately contact the part of the pressure holding box 300 to be tested, resulting in deviations in the testing data. To ensure the accuracy of the pressure holding box 300's placement on the testing platform 120 and its stability during testing, the testing platform 120 has a positioning protrusion 122 and a magnetic connector 123 on its surface facing the pressure holding box 300. When the pressure holding box 300 is placed on the testing platform 120, the positioning protrusion 122 provides clear guidance for its placement, allowing operators to quickly and accurately place the pressure holding box 300 on the testing platform 120 without spending a lot of time on repeated adjustments and calibrations, thus shortening the placement time of the pressure holding box 300 and improving the efficiency of the entire testing process. The magnetic connector 123 connects to the magnet 310 for automatic alignment and enhances the fixation of the pressure holding box 300 on the testing platform 120, ensuring that the pressure holding box 300 remains stable during testing, guaranteeing the reliability of the test data, reducing test failures or inaccurate data due to position changes, and avoiding the need for repeated testing due to the position of the pressure holding box 300.

[0025] In this embodiment, the gripping and lifting mechanism 200 includes grippers 210 and lifting components 220. Grippers 210 are located on the left and right sides above the detection platform base 120 and are used to hold the pressure holding box 300. The lifting components 220 include a drive cylinder 221, a lifting connecting plate 222, and several lifting guide rods 223. The fixed end of the drive cylinder 221 is located at the bottom of the machine base 100, and the telescopic end of the drive cylinder 221 is connected to the lifting connecting plate 222. One end of the lifting guide rod 223 is connected to the lifting connecting plate 222, and the other end of the lifting guide rod 223 passes through the equipment fixing plate 110 and is detachably connected to the grippers 210.

[0026] It should be noted that the grippers 210 are positioned on opposite sides above the detection platform base 120 to accurately control the position and orientation of the pressure holding box 300, ensuring that the pressure holding box 300 does not shift or tilt during the gripping process. For example, in one embodiment, as... Figure 6 The gripper 210 is equipped with protrusions, and the pressure holding box 300 has corresponding placement notches on both sides. When placing the pressure holding box 300, the placement notches face the protrusions, and the protrusions face the pressure holding box 300, contacting the inner surface of the placement notches. The gripper 210 descends with the lifting assembly 220 to the set position and places the pressure holding box 300 onto the testing platform base 120. The detachable connection between the gripper 210 and the lifting guide rod 223 allows the gripper 210 to be replaced to adapt to pressure holding boxes 300 of different specifications and sizes, improving the versatility and applicability of the equipment. In the lifting assembly 220, the lifting connecting plate 222 serves as the connecting component between the drive cylinder 221 and the lifting guide rods 223. It evenly distributes the force generated by the drive cylinder 221 onto each lifting guide rod 223, preventing excessive localized stress that could deform or damage the lifting guide rods 223. Simultaneously, the lifting connecting plate 222 and the multiple lifting guide rods 223 jointly bear the weight of the gripper 210 and the pressure box 300, as well as various forces generated during movement, ensuring structural stability during lifting. Under uniform force distribution, the lifting guide rods 223 accurately guide the movement of the gripper 210, ensuring that the gripper 210 does not deviate or wobble during movement. It is understood that the gripper 210 can employ existing technological structures, such as opening / closing structures or supporting structures, to grip or place the pressure box 300. It can also be connected to opening / closing adjustment or pushing components, which will not be elaborated upon here.

[0027] To further improve the motion accuracy and structural stability of the lifting assembly 220, several positioning guide rods 224 are provided at the bottom of the machine base 100. The positioning guide rods 224 pass through the lifting connecting plate 222 and connect to the equipment fixing plate 110. A guide sleeve is provided on the equipment fixing plate 110, and the lifting guide rods 223 pass through the guide sleeve. The positioning guide rods 224 provide precise linear guidance for the up-and-down movement of the lifting connecting plate 222. When the drive cylinder 221 pushes or pulls the lifting connecting plate 222, the positioning guide rods 224 can provide linear guidance for the up-and-down movement of the lifting connecting plate 222, ensuring that the lifting connecting plate 222 can only move in a straight line in the vertical direction, avoiding the entire lifting assembly 220 from shifting or swaying in the horizontal direction. The presence of the guide sleeve makes the movement of the lifting guide rods 223 more stable and precise.

[0028] In some embodiments, the gripping lifting mechanism 200 further includes a buffer 230 and a buffer guide post 240. The buffer 230 is connected to the lifting connecting plate 222, and the buffer guide post 240 is located at the bottom of the machine base 100 corresponding to the position of the buffer 230. It is understood that when the gripper 210 grips or places the pressure-holding box 300, the lifting connecting plate 222 moves to its limit position, generating an impact force. The buffer 230 is used to buffer the impact and reduce vibration, and the buffer guide post 240 provides precise guidance for the buffering process, ensuring that the buffer 230 can stably compress and recover along a predetermined direction when subjected to impact.

[0029] To improve the automation level of the entire equipment and avoid idling, the detection mechanism 400 also includes a detection grating 450 and a detection laser 460. The detection grating 450 is set on the outside of the gripper 210 facing away from the detection platform base 120. The detection grating 450 is used to detect whether the pressure holding box 300 is placed on the gripper 210. The detection laser 460 is set on the equipment fixing plate 110. The detection laser 460 is used to detect whether the pressure holding box 300 is placed on the platform base 120. It should be noted that during equipment operation, if the detection grating 450 detects that the gripper 210 has a pressure-holding box 300 placed on it, it will send feedback information to the control system. The control system will then send a command to initiate the above four checks on the pressure-holding box 300. If it detects that the gripper 210 does not have a pressure-holding box 300 placed on it, it will promptly send feedback information. The control system, considering the current operating stage of the gripper 210 (either waiting for the next placement of the pressure-holding box 300 or completing the check without placing the pressure-holding box 300), will send a command to control the lifting assembly 220 to keep the gripper 210 stationary or raise it, thereby preventing the equipment from proceeding due to an empty gripper 210. Invalid testing operations prevent equipment malfunctions due to misoperation and ensure stable equipment operation. After the gripper 210 places the pressure box 300 onto the testing platform 120, if the testing laser 460 detects that the pressure box 300 is accurately placed on the testing platform 120, the testing process of flatness testing, silicone hardness testing, and product molding block 121 pressure testing will start normally. If there is no pressure box 300 on the platform, the testing laser 460 will send a feedback signal, and the control system will control the equipment not to execute subsequent testing steps, avoiding the corresponding testing components from running idle, reducing equipment wear, and ensuring that the entire testing process is carried out in an orderly and reliable manner.

[0030] The magnetic field strength of magnet 310 affects the adsorption stability of pressure holding box 300, and thus affects the pressure holding performance of pressure holding box 300, such as... Figure 3The magnet 310 detection assembly 410 includes a magnetic field detection fixing plate 411, a push cylinder 412, and a push guide rod 413. The push cylinder 412 is mounted on the machine base 100 and is connected to the push guide rod 413. The push guide rod 413 is connected to the magnetic field detection fixing plate 411. A magnetic field strength detection needle 414 is mounted on the magnetic field detection fixing plate 411. The push cylinder 412 drives the push guide rod 413 to push the magnetic field detection fixing plate 411 out and retract. The magnetic field strength detection needle 414 is used to detect the Gauss value of the magnet 310. In the structure of the magnet 310 detection assembly 410, the magnetic field strength detection needle 414 is the core component. It can accurately measure the Gauss value of the magnet 310. It is set on the magnetic field detection fixing plate 411, which provides a stable support and mounting platform for the magnetic field strength detection needle 414, ensuring that the detection needle is accurately positioned and stable in posture during the detection process, thereby ensuring accurate detection results. Multiple magnetic field strength detection needles 414 can be set on the magnetic field detection fixing plate 411 at the same time. When the magnetic field detection fixing plate 411 is pushed out above the pressure box 300, multiple magnets 310 on the pressure box 300 are detected simultaneously, improving detection efficiency. The magnetic field detection fixing plate 411 is pushed out and retracted by the cooperation of the pushing cylinder 412 and the pushing guide rod 413, reducing the error and labor intensity of manual operation, and realizing efficient and stable operation of the magnet detection process.

[0031] like Figure 1 , Figure 5 In some embodiments, the flatness detection component 420 includes a plurality of displacement gratings 421 and a plurality of flatness detection heads 422. The displacement gratings 421 are disposed on the equipment fixing plate 110. Each flatness detection head 422 is correspondingly connected to a displacement grating 421. The flatness detection head 422 passes through the detection platform base 120 and contacts the pressure holding box 300 placed on the detection platform base 120. The displacement gratings 421 measure the displacement of the flatness detection head 422. It should be noted that the surface flatness of the pressure box 300 has a direct impact on its sealing performance, stability, and compatibility with supporting components. Several flatness detection heads 422 pass through the detection platform seat 120 and contact the pressure box 300 placed on it. When there are unevennesses on the surface of the pressure box 300, different flatness detection heads 422 will generate corresponding displacements at their contact points. The displacement grating 421 connected to each flatness detection head 422 can accurately measure these displacements. By analyzing these displacement data, the control system can accurately determine whether the flatness of the pressure box 300 surface meets the design requirements, promptly detect surface defects such as local depressions and protrusions, and ensure that the surface flatness of the pressure box 300 entering subsequent production or use stages is qualified.

[0032] The hardness of the silicone indenter 320 is one of the key factors affecting the performance of the pressure holding box 300. Appropriate hardness ensures that the pressure holding box 300 provides sufficient pressure during the pressure holding process without damaging the product due to excessive hardness or failing to achieve the desired pressure holding effect due to excessive softness. However, during mass production of the pressure holding box 300, the hardness of the silicone indenter 320 may fluctuate due to factors such as production batches and raw material differences. After repeated use, the silicone indenter 320 may age and harden. To address this, the equipment is equipped with a silicone hardness detection component 430 to detect the hardness of the silicone indenter 320. The silicone hardness detection component 430 includes a hardness tester 431 and a hardness detection probe 432. The hardness tester 431 is fixed on the equipment mounting plate 110, and the hardness tester 431 is connected to the hardness detection probe 432. The hardness detection probe 432 passes through the product molding block 121 and contacts the silicone indenter 320. It should be noted that the hardness tester 431 is tightly connected to the hardness test probe 432, which can accurately convert the hardness information of the silicone indenter 320 sensed by the test probe into an electrical signal and process it precisely. The hardness tester 431 is fixed on the equipment fixing plate 110, avoiding shaking and vibration caused by hand-held tester or tester movement, reducing the interference of external factors on the test process. At the same time, the product molding block 121 provides a stable support and guiding structure for the test probe, so that the test probe can maintain a stable posture when in contact with the silicone indenter 320, thereby ensuring the stability of the measurement force during the test and improving the stability of the test results.

[0033] like Figure 4 The pressure detection assembly 440 includes a pressure fixing block 441 and a pressure sensor 442. The pressure fixing block 441 is connected to the product molding block 121, and the pressure sensor 442 is connected between the pressure fixing block 441 and the base plate. The pressure fixing block 441 provides a stable mounting and support structure for the pressure sensor 442, avoiding measurement errors caused by unstable installation of the pressure sensor 442. Simultaneously, it can also disperse and buffer some of the pressure, preventing pressure concentration from damaging the pressure sensor 442. Furthermore, one or more pressure sensors 442 can be set to detect pressure values ​​at multiple points.

[0034] The method of using the above-mentioned pressure-holding box 300-point inspection equipment includes the following steps: S1 places the pressure-holding box 300 into the clamping and lifting mechanism 200, and the equipment starts testing; S2 Magnet 310 Detection: The magnet 310 detection component 410 is pushed out above the pressure box 300. The magnet 310 detection component 410 detects the Gauss value of the magnet 310 on the pressure box 300. The control system determines whether the Gauss value meets the set range. After the detection is completed, the magnet 310 detection component is retracted, the lifting mechanism descends, and the pressure box 300 is placed on the detection platform base 120. S3 Flatness Detection: After the pressure box 300 is placed on the detection platform seat 120, the contact surface between the pressure box 300 and the detection platform seat 120 and the flatness detection component 420 are in contact to perform flatness detection. The control system determines whether the flatness of the entire contact surface meets the set range based on the detection value of the flatness detection component 420. S4 Silicone Hardness Test: After the pressure box 300 is placed on the test platform seat 120, the silicone indenter 320 presses against the product molding block 121. The silicone hardness test component 430 contacts the silicone indenter 320 to perform hardness test. The control system determines whether the silicone hardness meets the set range based on the test value of the silicone hardness component. S5 Pressure Detection: After the pressure holding box 300 is placed on the detection platform seat 120, the pressure detection component 440 is pressurized along with the product molding block 121 to detect the pressure value, and the control system determines whether the pressure value is within the range. S6 Based on the test results of S2-S5, if all four test results are within the set range, the test is passed, and the pressure box 300 is removed for standby; if any one of the four test results is outside the set range, the test fails, the pressure box 300 is removed, and the test results are classified, stored, and processed accordingly.

[0035] It should be noted that pressure holding boxes 300 that fail the test are marked with non-compliance results. Operators will then make a comprehensive judgment on whether they need to be scrapped. If they do not need to be scrapped, corresponding adjustments or secondary processing will be performed. For example, in some specific operations, magnets 310 may be replaced, reinstalled, or supplemented based on the magnet 310 test results; points that do not meet the set range may be marked based on the flatness test results and secondary processing will be performed subsequently; silicone heads may be replaced based on the silicone hardness test results; and the internal structure of the pressure holding box 300 may be checked for deformation or damage based on the pressure test results, and structural adjustments or component replacements may be performed.

[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
