However, these electronic products often have a considerable amount of electromagnetic wave radiation, and when they are normally used, they are relatively close to human tissues, so that an induced electromagnetic field is generated in the human tissues.
Currently, the Specific Absorption Rate (SAR) is introduced to characterize the degree of influence of electromagnetic radiation on human tissue. In practical applications, SAR is a measurement defined as the electromagnetic power absorbed or consumed in a unit of time and a unit of mass of biological tissue (including human tissue), and is measured in W/kg.

In this process, the electronic product to be tested needs to be placed at a set position near the biological model (also called DASY model), and then the testing is performed. At present, the electronic product to be tested is placed mainly by placing a bracket near a DASY model, then the posture of the bracket is manually adjusted by a worker, and the electronic product to be tested is manually placed, so that the efficiency is low.

The embodiment of the application does not specially limit the concrete form of the prototype.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an embodiment of a prototype in the present application.
As shown in fig. 2, a mobile phone is taken as an example of the prototype 52, and the prototype 52 may generally include a front side 521, a back side (a side opposite to the front side 521 in fig. 2) and four side surfaces 522, and when performing the SAR test, the test can be performed on different surfaces. For convenience of understanding, the following description will be made by taking the prototype 52 as a mobile phone as an example
As described in the background art, the existing prototype placement scheme is bracket + manual placement. Firstly, aiming at different forms of prototypes, adaptive supports need to be arranged, so that the types of the supports are more; the support needs to have an adjustable function so as to be suitable for adjusting the placing posture of the prototype and further meet the test requirement, so that the structural form of the support is relatively complex; in addition, when the prototype is placed on the support, manual participation is inevitably needed, the automation degree is low, and the testing efficiency is also low.
In view of the above, the embodiment of the present application provides a prototype placement device 5, and the prototype placement device 5 can automatically place the prototype 52 by means of a displacement component and a visual positioning technology, and the automation degree of the device can be greatly improved without manual participation in the testing process. In addition, a bracket with a relatively complex structure and a relatively wide variety can be omitted, and the structure of the equipment can be simplified to a certain extent.
Referring to fig. 3 to fig. 6, fig. 3 is a schematic structural diagram of an embodiment of a prototype placement apparatus provided in the embodiment of the present application, fig. 4 is a structural diagram of placement of a shelf and a prototype in the embodiment of the present application, fig. 5 is a structural diagram of placement of a positioning component and a prototype in the embodiment of the present application, and fig. 6 is a structural diagram of connection between a second displacement component and a prototype in the embodiment of the present application.
As shown in fig. 3, the prototype placement apparatus 5 provided by the embodiment of the present application includes a second displacement component 51, a visual detection component 511, a shelf 53, and a positioning component 54.
The shelf 53 is used to store and place the prototype 52, and the prototype 52 can be placed on the shelf 53 in an initial state or in some intermediate state during the test (see the following description).
In a specific example, in conjunction with fig. 4, the shelf 53 can be provided with a carrier 531, and the carrier 531 can be provided with a carrying structure for carrying the prototype 52. The specific form of the bearing structure is not limited as long as the bearing reliability and the picking convenience of the prototype 52 by the second displacement part 51 can be ensured; in the embodiment of the figures, the carrying structure may be a substantially L-shaped carrying location for carrying both sides 522 of the prototype 52, so that the picking of the prototype 52 by the second displacement member 51 may be facilitated.
The number of the carrier 531 may be one or more. When the number of the bearing tables 531 is plural, the shelf 53 may further include a bottom frame 532, and each bearing table 531 may be mounted to the bottom frame 532 at intervals, and the specific mounting manner may be welding, screwing, riveting, bonding, or the like; at this time, the shelf 53 has a function of simultaneously carrying a plurality of prototypes 52, however, in a specific practice, the number of prototypes 52 carried by the shelf 53 may be smaller than the number of carrying platforms 531, that is, the shelf 53 may not be full; when a plurality of prototype machines 52 are mounted, the types of prototype machines 52 may be the same or different.
The second displacement component 51 is used for picking and displacing the prototype 52 so as to adjust the position of the prototype 52 and realize the transfer of the prototype 52 among the components; for example, the second displacement unit 51 may transfer the prototype on the rack 53 to the positioning unit 54, and the second displacement unit 51 may also be used to drive the prototype 52 to a set position near the biological model 4 for SAR detection. The structural form of the second displacement member 51 is not limited herein, and is specifically related to the motion path that the second displacement member 51 needs to realize; in some embodiments, the second displacement component 51 may be a manipulator, or may also be a three-degree-of-freedom displacement table or the like capable of moving in a horizontal direction, a longitudinal direction, and a vertical direction, and taking the manipulator as an example, the second displacement component 51 may be a six-axis manipulator to realize a motion with a larger degree of freedom.
In detail, the second displacement member 51 may be provided with an adsorption part and a vacuum-pumping member, which may be a vacuum pump or the like, for generating an adsorption force at the adsorption part, so that the prototype 52 may be adsorbed and picked up to transfer the prototype 52; with this solution, the second displacement member 51 only needs to cooperate with one face of the prototype 52, so that the prototype 52 can be picked up, and more faces of the prototype 52 can be exposed, which is more beneficial for testing. In practice, the second displacement member 51 may also be a pick-up member in the form of a gripper for picking up the prototype 52.
Referring to fig. 5, the positioning unit 54 includes a positioning stage 541, and the second shift unit 51 can transfer the prototype 52 to the positioning stage 541. The visual inspection unit 511 may be an industrial camera or the like, and is configured to visually inspect the prototype 52 placed on the positioning unit 54 to obtain the placement position of the prototype 52 relative to the positioning unit 54. As shown in fig. 3, the visual inspection part 511 may be integrally assembled to the second displacement part 51; alternatively, the visual detection unit 511 may be integrally mounted on the positioning unit 54; alternatively, the visual inspection unit 511 may be mounted at other positions of the prototype placement device provided in the embodiment of the present application, as long as the placement position of the prototype 52 on the positioning unit 54 can be visually inspected.
It should be understood that, after the components in the placement device for prototypes provided by the embodiment of the present application are fixedly assembled, the position of the positioning component 54 is known, so that after the placement position of the prototype 52 relative to the positioning component 54 is obtained by the visual detection component 511, the position of the set picking position of the prototype 52 can be accurately obtained, and then, the set picking position can be suction-picked by the second displacement component 51. Thus, on the one hand, the reliability of the adsorption and positioning of the prototype 52 can be ensured, and the situation that the prototype 52 falls off accidentally due to poor adsorption position can be avoided to a great extent, and on the other hand, the subsequent accurate movement of the prototype 52 to the set position near the biological model 4 is facilitated. The specific position of the set picking position is not limited herein, and is specifically related to the shape and size of the prototype 52; taking the prototype 52 as an example of a mobile phone, the set pickup location generally refers to a central area of the front or back of the mobile phone.
When in specific use, a certain number of sample machines 52 can be placed on the shelf 53; then the corresponding prototype 52 is picked up by the second displacement member 51 and the prototype 52 is transferred to the positioning member 54; under the action of the visual detection component 511, the set picking position of the prototype 52 can be determined, and the second displacement component 51 can pick the prototype 52 again at the set picking position; then, the prototype 52 can be moved by the second displacement member 51 to a set position near the biological model 4 to facilitate the development of the SAR test. In the process, the second displacement component 51 can be matched with the visual detection component 511, the placement of the prototype 52 can be automatically completed, manual participation is basically not needed in the placement process, and the testing efficiency can be greatly improved.
The aforementioned setting position may be specifically given by the second control module 55. The second control module 55 and the aforementioned first control module may be provided integrally, or the second control module 55 may be separately configured. The set position may be calculated by the second control module 55 according to the type information, the shape information, and the like of the biological model and the shape information, and the like of the prototype 52, and the specific calculation method is not limited herein. The type information, the shape information, and the like of the biological body model, the shape information, and the like of the prototype 52, and the like may be manually input values. Alternatively, the information may be pre-stored in the second control module 55 for ready recall; taking the prototype 52 as an example, the prototype 52 may be configured with identification information capable of indicating an identity, the visual detection component 511 may capture and read the identification information, and the second control module 55 may automatically retrieve corresponding shape information from the database after receiving the identification information.
In addition, the shape information may be detected and acquired. For example, the positioning component 54 may be further provided with an infrared detection mechanism (not shown), which can accurately detect the shape information of the prototype 52, such as size information, position information of components such as a camera or a handset, and the like. For a detailed description, the positioning stage 541 may be made of transparent material, such as glass, and an infrared detection mechanism may be disposed below the positioning stage 541 to detect the above-mentioned shape information. In fact, the visual inspection unit 511 described above can also be used to detect profile information of the prototype 52.
The second control module 55 can also be in signal connection with the second displacement part 51 and the prototype 52 and is used for controlling the second displacement part 51 to displace according to a set path and carrying out adsorption pickup on the prototype 52; moreover, the second control module 55 can also be used to control the working scenarios of the prototype 52, for example, the prototype 52 is adjusted to a call state, a hot spot starting state, a music playing state, etc., so that the prototype 52 can have different output powers, and the SAR values under different working scenarios can be conveniently tested.
The signal connection of the second control module 55, the second displacement member 51, the prototype 52, the infrared detection mechanism, etc. may be a cable connection. Taking the prototype 52 as an example, the prototype 52 can be provided with a numerical control interface in the form of a USB socket or the like, and the control cable can be fixed on the shelf 53; thus, when the prototype 52 is positioned on the shelf 53, the signal connection relation between the prototype 52 and the second control module 55 can be established, and at this time, the shelf 53 has the functions of data transmission and control besides the function of bearing the prototype 52; with the arrangement, the corresponding working scene of the prototype 52 needs to be opened or switched before the prototype 52 is separated from the shelf 53, and after the prototype 52 is separated from the shelf 53, the working scene of the prototype 52 is in a locked state and cannot be changed.
In addition, the signal connection mode between the second control module 55 and the second displacement part 51, the prototype 52, the infrared detection mechanism, etc. may also be wireless connection, such as bluetooth connection, wifi connection, etc., so as to omit the connection cable, thereby simplifying the structure. Moreover, in the embodiment, the working scene of the prototype 52 can be started or switched at any position, the dependence on the shelf 53 is not required, and the function of the shelf 53 can be simplified. The prototype 52 does not need to be started early, and the prototype 52 can be started after being moved to the set position through the second displacement part 51, so that the power consumption of the prototype 52 can be reduced.
The prototype 52 may be plugged with a SIM (Subscriber identity Module) card, and an operating company to which the SIM card belongs may not be limited, so that the prototype 52 may operate under a network of a specific operator, and thus, an SAR value of the prototype 52 when operating under the network of the specific operator may be detected. The test is closer to the user level, and the test result is also closer to the actual application situation of the user.
In this embodiment, a dedicated base station simulator 56 may be further configured, where the base station simulator 56 may be specifically an integrated tester or the like, and may output one or more network signals, such as a 4G network signal or a 5G network signal. Unlike the direct use of SIM cards, the configuration of the base station simulator 56 makes the network signal more stable, avoids interference caused by signal instability, and achieves a higher accuracy of the SAR value based on the set network signal. The switching of the network signal of the base station simulator 56 may be controlled by an operation key or the like provided thereon, or a signal transmission relationship between the base station simulator 56 and the second control module 55 may be established, and then the network signal output by the base station simulator 56 may be switched by the second control module 55.
The SAR test system provided in the embodiment of the present application may further be provided with a detection component (not shown in the figure) for monitoring the communication state and the communication quality of the base station simulator 56 in real time, and if the communication is disconnected or the communication quality is poor, the detection needs to be suspended, and related devices are debugged and maintained.
As described above, the prototype 52 in the form of a mobile phone or the like includes the front 521, the back, and the four side surfaces 522, and when the SAR detection is performed, the front 521, the back, and the side surfaces 522 can be detected separately.
For this reason, the suction lever 515 of the second robot arm 51 in the embodiment of the present application may be provided with two types of suction portions. In conjunction with fig. 6, for convenience of description, they may be referred to as a first adsorption part 512 and a second adsorption part 513, respectively. Wherein, the first adsorption part 512 is arranged on the peripheral wall of the adsorption rod 515, and after adsorbing and fixing the front surface 521 or the back surface of the prototype 52, the front surface 521 or the back surface of the prototype 52 and the axial direction of the adsorption rod 515 are in a state of being basically parallel; the second suction portion 513 is provided at an end of the suction rod 515, and after the front side 521 or the back side of the prototype 52 is sucked and fixed, the front side 521 or the back side of the prototype 52 is in a state of being substantially perpendicular to the axial direction of the suction rod 515. The two different adsorption states of the prototype 52 against the adsorption bar 515 allow the prototype 52 to have a wider variety of pose.
In particular practice, the prototypes 52 adsorbed to the first adsorption part 512 may be used for testing four sides 522, and the prototypes 52 adsorbed to the second adsorption part 513 may be used for testing the front 521 or the back. Of course, it is also possible that the prototype 52 adsorbed on the first adsorption part 512 is used for testing the front side 521 or the back side, and the prototype 52 adsorbed on the second adsorption part 513 is used for testing the four side surfaces 522.
When switching between the first suction unit 512 and the second suction unit 513, the separation of the prototype 52 from the second robot arm 51 needs to be controlled first, and thus the prototype 52 needs to be placed on a certain member first. Specifically, the prototype 52 may be placed on the shelf 53 (in the intermediate state, the case where the prototype 52 needs to be placed on the shelf 53), and then the posture of the second robot arm 51 may be adjusted to perform suction pickup on the prototype 52 by using different suction portions; then, the positioning by the positioning member 54 is performed again so that the suction portion sucks the prototype 52 at the set pickup position.
In fact, the prototype 52 can be directly transferred to the positioning member 54, and thus the second displacement member 51 can directly suck the prototype 52 at the set pickup position after switching the suction portion, and the step of getting on the shelf 53 can be omitted, and the operation can be more speedy.
With continued reference to fig. 1, the prototype placement apparatus provided in the embodiment of the present application may further include a turning component 57, which is used to turn the front side 521 and the back side of the prototype 52, so as to facilitate the detection of the front side 521 and the back side of the prototype 52 respectively. Specifically, after one of the front and back surfaces of the prototype 52 is detected, the prototype 52 may be transferred to the turning member 57 by the second displacement member 51, and the prototype 52 may be turned by the turning member 57; then, the second shift member 51 can transfer the prototype 52 to the positioning member 54 again for positioning, so that the suction portion can suction-pick the prototype 52 at the set pickup position.
Referring to fig. 7, fig. 7 is a schematic structural diagram of the turning part in the embodiment of the present application.
The structure of the turning part 57 can be varied as long as the turning of the front and back of the prototype 52 can be realized. In a specific example, as shown in fig. 7, the turning component 57 may include a clamping mechanism, the clamping mechanism includes a first clamping portion 571 and a second clamping portion 572 which are oppositely arranged, and the two clamping portions may be driven by air pressure or hydraulic pressure to move toward or away from each other so as to clamp and release the prototype 52; the turning part 57 may further include a turning driving member 573, and the turning driving member 573 may be a driving element capable of outputting rotational displacement in the form of a motor, a rotary cylinder, or the like, and may be in transmission connection with the clamping mechanism for driving the clamping mechanism to rotate, so as to turn the front side 521 and the back side of the prototype 52.
In detail, the second displacement member 51 can move the prototype 52 between the first clamping portion 571 and the second clamping portion 572; the turning part 57 may be provided with a sensing element, and after the model 52 is sensed to be put in, the first clamping part 571 and the second clamping part 572 may approach each other and clamp the model 52; then, the second displacement member 51 can release the suction to the prototype 52; flip drive 573 can be activated to flip prototype 52; after the overturning is completed, the second displacement part 51 can adsorb the prototype 52 again; then, the first and second clamping portions 571 and 572 can be moved away from each other to release the clamping with respect to the prototype 52. By doing so, the safety of the prototype 52 during the overturning process can be ensured to the maximum extent so as to avoid the falling of the prototype 52.
Further, the second robot arm 51 may be provided with a force sensor 514 capable of detecting the magnitude of the suction force. The type of force sensor 514 is not limited herein.
The second control module 55 may have a pre-stored upper limit F of the adsorption force MAX And lower limit of adsorption force F MIN . If the force sensor 514 detects the real-time value F of the adsorption force<F MIN If the adsorption force is too small, the adsorption reliability is poor, and the risk that the prototype 52 falls off may exist; at this time, the second control module 55 may send an alarm message to the outside to prompt the human to participate. If the force sensor 514 detects the real-time value F of the adsorption force>F MAX This indicates that the suction force is too large, and in this case, there is a possibility that the sample 52 will be touchedThe shell is damaged, and the second control module 55 can send out alarm information to prompt people to participate. The upper limit value F of the adsorption force MAX And lower limit value of adsorption force F MIN The specific values of (a) are not limited herein, and are specifically related to the size, shape, weight, etc. of the prototype 52.
The specific type of alarm information sent by the second control module 55 is not limited herein. For example, the following steps are carried out: the alarm information may be sound alarm information, and at this time, the second control module 55 may be configured with a sound alarm in the form of a buzzer alarm or the like; or, the second control module 55 may be configured with an optical alarm; or, an audible and visual alarm message may also be used, and in this case, the second control module 55 may be configured with an audible and visual alarm; alternatively, when the second control module 55 has a display interface, the alarm information can also be displayed directly on the display interface, such as "Warning! "or the like text alarm information or pop-up window information, etc.
The second robot arm 51 may also have a lock function, that is, in the event of an unexpected power failure or an unexpected interruption of a control signal of the second control module 55, the suction force of the second robot arm 51 may not be released to prevent the prototype 52 from falling.
Based on the prototype placement device related to the above embodiments, the following embodiments of the present application further provide a use method for the prototype placement device, which may specifically include the following steps: step S101, controlling the second displacement component 51 to transfer the model machine 52 of the goods shelf 53 to the positioning component 54; step S102, carrying out visual detection on the prototype through the visual detection part 511 to obtain a set picking part of the prototype 52; step S103, controlling the second displacement component 51 to pick the prototype 52 at the set picking position; in step S104, the second displacement unit 51 is controlled to move the prototype 52 to a set position near the biological model 4.
As mentioned above, the use method is implemented without manual participation basically, and can automatically complete the placement of the prototype 52, which is beneficial to improving the SAR test efficiency; in the above-described method of use, the position at which the second displacement unit 51 picks up the prototype 52 can be adjusted by the cooperation of the visual detection unit 511 and the positioning unit 54, and the reliability of the picking up of the prototype 52 can be ensured to a large extent.
It should be noted that the designations of the method steps such as "S101" and "S102" appearing herein are merely for convenience of naming, labeling and referencing the corresponding method steps, and do not necessarily indicate the importance and/or order of the relationship between the steps.
Further, the prototype placement device further comprises a second control module 55 for controlling the working scene of the prototype 52, and thus, the using method further comprises: and step S105, controlling the prototype 52 to start or switch the set working scene through the second control module 55. In this way, the test of the SAR value of the prototype 52 under the set working scenario can be completed, which is not limited herein.
As previously described, the signal transmission between the prototype 52 and the second control module 55 may be a cable connection, for example, by providing a cable on the shelf 53 to realize the signal connection between the prototype 52 and the second control module 55; thus, the above-described step S5 needs to be completed before step S1, that is, before the prototype 52 is detached from the shelf 53. Alternatively, the signal transmission between the prototype 52 and the second control module 55 may be wireless connection, and at this time, there is no specific sequence between the step S105 and the step S101 to the step S104, as long as the step S5 is completed before the SAR test is started; the above-described step S105 may be performed after the step S104 in view of reducing the consumption of power.
The setting position in step S104 may be specifically given by the second control module 55. The calculation of the set position is related to information such as the type and the shape of the biological model and information such as the shape of the prototype 52. The information on the type, shape, etc. of the biological model and the information on the shape, etc. of the prototype 52 may be manually input by the operator at the time of use, or may be pre-stored in the second control module 55, as described above.
Alternatively, information on the type, shape, and the like of the biological model, information on the shape of the prototype 52, and the like may be acquired by detection. Thus, step S106 may be further included before step S4: the shape information of the prototype 52 is detected, and the shape information may specifically include size information, position information of a component such as a camera or a handset, and the like.
The structural form of the part for detecting the shape information of the prototype 52 is not limited herein as long as the above technical effects can be achieved, and it may be a camera, for example. In the embodiment of the present application, an infrared detection mechanism is preferably used to improve the accuracy of the detection result. Further, the infrared detection mechanism may be provided to the positioning member, so that the above step S106 may be executed in synchronization with the step S102.
The prototype 52 may be fitted with a SIM card or alternatively, a dedicated base station simulator 56 may be provided. In the scheme for configuring the base station simulator 56, the using method provided by the embodiment of the present application further includes step S107: and controlling the base station simulator 56 to switch to the set network signal so as to test the SAR value of the prototype 52 under the set network signal. This step S107 may be performed before step S105.
Specifically, the step S107 can be executed by the second control module 55, that is, the base station simulator 56 can be controlled by the second control module 55.
Referring to fig. 2, the prototype 52 in the form of a mobile phone or the like generally includes a front 521, a back and four sides, and the above steps S101-S104 actually only complete the testing of the front 521 or the back or the four sides. Taking the pick-up component shown in fig. 6 as an example, the second displacement component 51 includes two suction portions, wherein the tests of the front surface 521 and the back surface can share the same suction portion, but the turning component 57 needs to be introduced to turn the prototype 52, and the tests of the four side surfaces can use the other suction portion; in this way, regardless of which side the test is completed in the above steps S101 to S104, the suction portion needs to be replaced and the other side needs to be turned over when the test is performed on the other side.
For convenience of description, the above steps S101 to S104 are only performed to test the four side surfaces 522, and the first suction unit 512 is used to suck the prototype 52 as an example. Then, the step S103 may specifically be: the step S104 of controlling the second displacement unit 51 to pick up the prototype 52 at the set picking position by the first adsorption unit 512 may specifically be: the second displacement means 51 is controlled to transfer the four side surfaces of the prototype 52 to the set positions near the biological model 4.
After testing of the four sides 522 is completed, the front 521 may be tested first, and the back may be tested last. Thus, the use method can further comprise the following steps: step S108, after the test of the four sides is finished, the prototype 52 is transferred to the shelf 53 through the second displacement part 51; step S109, controlling the second displacement member 51 to switch to the second adsorption part 513, and repeatedly executing the above steps S101 and S102; step S110, controlling the second displacement component 51 to pick the prototype 52 at the set picking position by the second adsorption part 513; step S111, controlling the second displacement component 51 to transfer the front 521 of the prototype 52 to a set position near the biological model; step S112, after the test of the alignment surface 521 is completed, the prototype 52 is transferred to the overturning part 57 through the second shifting part 51; step S113, controlling the overturning part 57 to overturn the prototype 52; step S114, controlling the second displacement means 51 to transfer the prototype to the positioning means 54, and repeatedly executing the aforementioned steps S102 and S110; in step S115, the second displacement unit 51 is controlled to move the back surface of the prototype 52 to a set position near the biological model.
In the above steps, step S108 may be omitted, that is, after the four-side test is completed, the second displacement member 51 may directly transfer the prototype 52 to the positioning member 54 to perform the switching of the suction portion and the re-positioning pickup of the prototype 52.
It is understood that, the above steps S101 to S115 are performed by testing each surface of the prototype 52 in the test sequence of four side surfaces, a front surface and a back surface, and if the test sequence is changed, the corresponding steps are also changed. For example, when the front side is tested, after the front side test is completed, the prototype 52 can be directly transferred to the turning part 57 to be turned over, then the positioning part 54 is positioned and picked up, and the back side test is performed, then the switching and the positioning and picking up of the adsorption part can be completed at the positioning part (or the shelf 53 is firstly positioned to complete the switching of the adsorption part, then the positioning part is positioned and picked up), and then the test of the four side surfaces 522 is performed; the case of testing the back side first, then the front side and the four sides and the like will not be described repeatedly herein. Of course, in a specific practice, there may be a case where after one of the front and back surfaces is tested, the four side surfaces are directly tested, and then the other of the front and back surfaces is tested, in which case, two times of switching of the adsorption portions are required, and a use process is relatively complicated.
Further, the use method provided by the embodiment of the application can further comprise an adsorption force monitoring strategy, and the strategy can be triggered when the second mechanical arm 52 carries out adsorption pickup on the prototype 52. The method specifically comprises the following steps: step S201, acquiring a real-time detection value F of the adsorption force of the second mechanical arm 52; step S202, judging whether the real-time detection value F is larger than the adsorption force upper limit value F MAX Or less than the lower limit value F of the adsorption force MIN If yes, executing the following step S203; and step S203, sending alarm information. The kind of the alarm information can be referred to the foregoing description.
By such arrangement, the situation that the prototype 52 falls down due to too small adsorption force or is damaged due to too large adsorption force can be avoided to a greater extent, and the safety of the test process can be improved to a greater extent.
The foregoing is only a preferred embodiment of the present application and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
