Description

Technical Field

[0001] This invention belongs to the field of terminal device testing, and particularly relates to testing equipment and notebook computer production lines. Background Technology

[0002] The wireless communication module is a key functional component of a laptop, and its radio frequency (RF) performance directly determines the end-user's network experience. Therefore, rigorous RF testing of each laptop on the production line is a core step in ensuring product quality.

[0003] Currently, a typical RF testing process involves connecting the laptop under test (BUT) to the testing equipment and conducting signal transmission and reception in a controlled environment to evaluate key indicators such as transmit power and receive sensitivity. However, existing laptop testing equipment often suffers from the following limitations during loading and testing: the production workshop environment is susceptible to interference during testing, such as radiation from the inverters of production equipment and co-channel or adjacent-channel interference from the workshop's Wi-Fi network. In such a testing environment, the inherent performance of the equipment cannot be accurately reflected, easily leading to misjudgments of product performance. In addition, existing production lines often use a single testing station. A laptop must complete all tests and be removed before the next one can enter the station for testing. The time required for testing itself, combined with the preparation time for loading, unloading, and connection, results in a large amount of idle waiting time throughout the process, thus slowing down the overall production line cycle time and reducing testing efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a testing device and a laptop computer production line, aiming to solve the problems of how to improve the accuracy and efficiency of testing.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a testing apparatus is provided, comprising a feeding station and a testing station along a first direction. The testing apparatus includes a conveying structure for conveying material along the first direction, a feeding platform slidably disposed vertically at the feeding station for carrying the material, a testing structure disposed at the testing station, and a material transfer structure disposed at the testing station. Multiple testing structures and conveying structures are arranged at intervals along the vertical direction, with each testing structure corresponding to a specific conveying structure. Each testing structure includes a housing with a shielded cavity and a testing component disposed within the shielded cavity. The feeding platform receives the material at the feeding station and moves the material to any of the conveying structures. The conveying structure receives the material at the feeding platform and moves the material to the corresponding testing structure. The material transfer structure receives the material at the conveying structure and transfers the material into the shielded cavity. The testing component detects the material.

[0007] In some embodiments, the material transfer structure includes a plurality of transport mechanisms spaced apart, each transport mechanism corresponding to a specific housing. Each housing has an opening communicating with the shielding cavity and facing the transport mechanism. The transport mechanism receives the material on the conveying structure and transports the material into the shielding cavity through the opening.

[0008] In some embodiments, the conveying mechanism includes a mounting base slidably disposed in a vertical direction and a transfer platform slidably connected to the mounting base in a second direction, the second direction being angular to the first direction. The conveying structure has a conveying surface for supporting the material, the conveying surface having a lifting channel for the mounting base to slide. The conveying structure conveys the material above the transfer platform, the mounting base slides upward to allow the transfer platform to lift the material away from the conveying surface, and the transfer platform slides toward the opening to allow the material to enter the shielding cavity.

[0009] In some embodiments, the conveying structure includes a conveyor line for conveying the material, the conveyor line extending along the first direction, two conveyor lines arranged at intervals, the two conveyor lines respectively supporting opposite ends of the material, and the lifting channel forming between the two conveyor lines.

[0010] In some embodiments, the conveyor line includes a first frame and a second frame spaced apart from the first frame along the second direction. The first frame and the second frame are respectively connected to a first belt and a second belt. The first belt and the second belt jointly support the material. The second frame is slidably disposed relative to the first frame along the second direction to adjust the distance between the first belt and the second belt.

[0011] In some embodiments, the testing apparatus further includes a barcode scanning structure disposed on the feeding platform, the barcode scanning structure being used to scan the material located on the feeding platform to read information about the material.

[0012] In some embodiments, the test assembly includes a plurality of test elements spaced apart, each test element being used to test the material; the test structure further includes a clamping mechanism disposed within the shielding cavity, the clamping mechanisms being spaced apart and each clamping mechanism corresponding to each test element; the clamping mechanism includes a linear adjustment member and a rotating member rotatably connected to the linear adjustment member, the test element being connected to the rotating member, the linear adjustment member being used to drive the rotating member to move in a straight line to adjust the position of the test element, and the rotating member being used to drive the test element to rotate around a preset axis to adjust the orientation of the test element relative to the material.

[0013] In some embodiments, multiple test structures are arranged at intervals along the first direction, and each test structure arranged at intervals along the first direction corresponds to the same conveying structure, which is used to move the material to any of the test structures.

[0014] In some embodiments, the testing device includes a material unloading station, and the material loading station, the testing station, and the material unloading station are arranged sequentially along the first direction. The material unloading station includes a discharge conveyor line and a material unloading platform that slides vertically. The material unloading platform slides to dock with any of the conveying structures and receives the material after testing. The material unloading platform moves the material to the discharge conveyor line. The discharge conveyor line receives the material at the material unloading platform and unloads the material.

[0015] Secondly, a notebook computer production line is provided, which includes the testing apparatus described above.

[0016] The beneficial effects of this application are as follows: When the testing device of this application is in use, the feeding platform receives the material to be tested at the feeding station and moves the material to any conveying structure. After receiving the material from the feeding platform, the conveying structure moves the material to the corresponding testing structure. The material transfer structure receives the material from the conveying structure and conveys the material to the shielded cavity. The testing components in the shielded cavity test the material. The shielded cavity creates an independent and isolated electromagnetic environment for the material, effectively shielding external electromagnetic interference, thereby greatly improving the accuracy of the test. Furthermore, by arranging multiple layers of conveying structures and multiple layers of testing structures at intervals along the vertical direction, multiple materials to be tested can be transported to different testing structures in parallel for synchronous testing, which greatly shortens the testing time and improves the testing efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0029] Please see Figures 1 to 5This application provides a testing device, which includes a loading station 300 and a testing station 400 along a first direction a. The testing device includes a conveying structure 30 for conveying material 200 along the first direction a, a loading platform 10 slidably disposed at the loading station 300 along the vertical direction c and used to carry the material 200, a testing structure 40 disposed at the testing station 400, and a material transfer structure 20 disposed at the testing station 400. Multiple testing structures 40 and conveying structures 30 are arranged at intervals along the vertical direction c. Each testing structure 40 and each conveying structure... 30 correspond one-to-one; the test structure 40 includes a box 41 with a shielding cavity 411 and a test component 42 disposed in the shielding cavity 411; the loading platform 10 receives the material 200 at the loading station 300 and moves the material 200 to any conveying structure 30, the conveying structure 30 receives the material 200 at the loading platform 10 and moves the material 200 to the corresponding test structure 40; the material transfer structure 20 receives the material 200 at the conveying structure 30 and transfers the material 200 to the shielding cavity 411, and the test component 42 detects the material 200.

[0030] It should be noted that the material 200 provided in this embodiment is a laptop computer, and the test structure 40 tests the laptop computer. Specifically, the test structure 40 can test the Wi-Fi antenna signal reception performance of the laptop computer, etc. Understandably, the laptop computer under test typically has two or more Wi-Fi antennas installed in different locations within the laptop to avoid simultaneous obstruction. The test structure 40 in this embodiment can also test whether multiple antennas can work together to improve performance. Of course, in other possible embodiments, the material 200 can also be other electronic devices; this application does not limit the specific type of the material 200.

[0031] In this embodiment, the testing device is provided with a loading station 300 and a testing station 400 along a first direction a. A conveying structure 30 is used to convey material 200 along the first direction a. Optionally, the first direction a is a horizontal direction, meaning the conveying direction of the material 200 is perpendicular to the moving direction of the loading platform 10. The loading platform 10 can slide in the vertical direction c, allowing it to flexibly transfer material 200 to any layer of the conveying structure 30. This is equivalent to stacking the existing horizontally linearly distributed testing structures 40 in the vertical direction, thereby fully utilizing the vertical height space and significantly reducing the footprint of the testing device.

[0032] Optionally, the testing device further includes a lifting driver 60, to which the loading platform 10 is connected. The lifting driver 60 can drive the loading platform 10 to rise and fall, and accurately dock the loading platform 10 with any conveying structure 30. Optionally, the lifting driver 60 is a linear module that extends in the vertical direction c.

[0033] In this embodiment, the loading station 300 is used to load the material 200 to be tested onto the loading platform 10. The loading station 300 can be connected to the previous workstation, or to a transfer trolley or robotic arm, etc. In addition, after receiving the material 200 from the loading platform 10, the conveying structure 30 can move the material 200 to any position on the conveying structure 30 and stop it.

[0034] In use, the testing device of this application has the following steps: the loading platform 10 receives the material 200 to be tested at the loading station 300 and moves the material 200 to any of the conveying structures 30. After receiving the material 200 from the loading platform 10, the conveying structure 30 moves the material 200 to the corresponding testing structure 40. The transfer structure 20 receives the material 200 from the conveying structure 30 and transfers the material 200 to the shielding cavity 411. The testing component 42 in the shielding cavity 411 tests the material 200. The shielding cavity 411 creates an independent and isolated electromagnetic environment for the material 200, effectively shielding external electromagnetic interference, thereby greatly improving the accuracy of the test. Furthermore, by arranging multiple layers of conveying structures 30 and multiple layers of testing structures 40 at intervals along the vertical direction c, multiple materials 200 to be tested can be transported in parallel to different testing structures 40 for synchronous testing, greatly shortening the testing time and improving the testing efficiency.

[0035] Understandably, the embodiments of this application also include a control system (not shown in the figure). The conveying structure 30, the lifting driver 60, the feeding platform 10, the transferring structure 20, and the testing structure 40 are all communicatively connected to the control system. The control system can control the automatic coordination and operation of the conveying structure 30, the lifting driver 60, the feeding platform 10, the transferring structure 20, and the testing structure 40. The entire process is greatly automated through the automatic coordination and operation of the conveying structure 30, the lifting driver 60, the feeding platform 10, the transferring structure 20, and the testing structure 40, which reduces manual operation and greatly improves the efficiency of feeding and testing.

[0036] In this embodiment, the enclosure 41 can be made of a material with high magnetic permeability and high electrical conductivity, such as cold-rolled steel plate or galvanized steel plate, so that the enclosure 41 can reflect electromagnetic waves or absorb and attenuate electromagnetic waves, thereby providing a good shielding effect against electromagnetic interference and providing key protection for accurate radio frequency testing.

[0037] In some embodiments, such as Figure 2 and Figure 3As shown, the material transfer structure 20 includes multiple conveying mechanisms 21 spaced apart, each conveying mechanism 21 corresponding to a box 41. Each box 41 has an opening 412 communicating with a shielding cavity 411 and facing the conveying mechanism 21. The conveying mechanism 21 receives material 200 on the conveying structure 30 and conveys the material 200 into the shielding cavity 411 through the opening 412. Understandably, the test structure 40 also includes a door plate 46 rotatably connected to the box 41. The door plate 46 can open or close the opening 412. When it is necessary to convey material 200 into the shielding cavity 411 via the conveying mechanism 21, the door plate 46 rotates to open the opening 412, facilitating the entry of the conveying mechanism 21. After the conveying mechanism 21 has finished conveying and exited, the door plate 46 rotates to close the opening 412, thus beginning the testing of the material 200. Once the test is completed, the door panel 46 reopens the opening 412, and the conveying mechanism 21 re-enters the shielded cavity 411 to remove the tested material 200 and releases it to the conveying structure 30, which can then transport the material 200 to the next workstation.

[0038] Understandably, in this embodiment of the application, each box 41 is equipped with an independent handling mechanism 21, which means that the loading and unloading actions of all test structures 40 can be carried out synchronously. For example, when the first material 200 is sent into a box 41 on a certain layer for testing, the handling mechanism 21 on other layers can simultaneously send the second material 200 into a box 41 on another layer for testing. Compared with a single material handling mechanism loading and unloading each box 41 sequentially, the waiting time can be shortened and the work efficiency can be further improved. Moreover, each handling mechanism 21 only needs to be responsible for a fixed, short-distance linear motion path. Compared with using a complex robot that needs to move over a wide range in three-dimensional space, the motion trajectory is simpler and more direct, the mechanical structure is easier to design and manufacture, and it is beneficial to reduce maintenance costs.

[0039] In some embodiments, such as Figure 3 As shown, the conveying mechanism 21 includes a mounting base 211 slidably disposed along the vertical direction c and a transfer platform 212 slidably connected to the mounting base 211 along a second direction b. The second direction b is angled to the first direction a. The conveying structure 30 has a conveying surface 32 for supporting the material 200. The conveying surface 32 is provided with a lifting channel 33 for the mounting base 211 to slide. The conveying structure 30 conveys the material 200 above the transfer platform 212. The mounting base 211 slides upward so that the transfer platform 212 lifts the material 200 to a position away from the conveying surface 32. The transfer platform 212 slides toward the opening 412 so that the material 200 enters the shielding cavity 411. Optionally, the second direction b is perpendicular to the first direction a and the vertical direction c.

[0040] Understandably, in the non-working state, the transfer stage 212 and mounting base 211 are hidden below the conveying surface 32, without occupying additional external space, which helps to make the overall structure of the device more compact. By setting the transfer stage 212 and mounting base 211, the transfer path of the material 200 is decomposed into two simple and efficient actions: the mounting base 211 slides upward, the transfer stage 212 vertically lifts the material 200, causing it to detach from the conveying surface 32, and the transfer stage 212 slides horizontally, directly sending the material 200 into the shielding cavity 411 of the housing 41. This process avoids complex multi-axis linkage, reduces the attitude interference to the material 200, and thus reduces damage to the material 200. Optionally, the mounting base 211 is connected to a sliding driver 213, which drives the mounting base 211 to slide in the vertical direction c. Optionally, the sliding driver 213 is a linear module.

[0041] Optionally, such as Figure 3 and Figure 5 As shown, the test structure 40 also includes a support platform 44 disposed in the shielding cavity 411. Two support platforms 44 are arranged at intervals along the first direction a. The two support platforms 44 are respectively used to support the two ends of the material 200. A channel is formed between the two support platforms 44 for the transfer platform 212 to slide. The transfer platform 212 slides between the two support platforms 44. At this time, the height of the bearing surface of the transfer platform 212 is greater than the bearing surface of the support platform 44. The mounting base 211 drives the transfer platform 212 to descend. The transfer platform 212 passes through the channel between the two support platforms 44, so that the material 200 on the transfer platform 212 falls onto the two support platforms 44. Then the transfer platform 212 withdraws. Conversely, after the test is completed, the transfer platform 212 extends into the shielding cavity 411 and is located below the material 200. The mounting base 211 drives the transfer platform 212 to rise, so that the transfer platform 212 lifts the material 200 to a position away from the bearing surface of the support platform 44. Then the transfer platform 212 withdraws, completing the material removal.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the transfer table 212 is provided with a stop block 214 and a push block 215 spaced apart from the stop block 214. The push block 215 is slidably disposed along the second direction b. The push block 215 can slide toward the stop block 214, so that the push block 215 and the stop block 214 jointly clamp the material 200, thereby improving the stability of the material 200 on the transfer table 212. Understandably, the push block 215 can also slide away from the stop block 214, thereby releasing the clamping of the material 200. Optionally, the push block 215 is connected to a push cylinder, which is used to drive the push block 215 to slide along the second direction b.

[0043] In some embodiments, such as Figure 3 and Figure 4As shown, the conveying structure 30 includes a conveyor line 31 for conveying material 200. The conveyor line 31 extends along a first direction a, and two conveyor lines 31 are arranged at intervals. The two conveyor lines 31 are respectively used to support the opposite ends of the material 200, and a lifting channel 33 is formed between the two conveyor lines 31. In this embodiment, the two conveyor lines 31 jointly support and convey the material 200, and the lifting channel 33 is formed between them, so that the mounting base 211 and the transfer platform 212 can be hidden below the conveying surface 32 and only rise through the lifting channel 33 when lifting is required. This makes the movement space of the conveying surface 32 of the material 200 and the mounting base 211 overlap in the vertical direction, eliminating the need to open up additional space outside the conveyor line 31 for installing the mounting base 211 and the transfer platform 212, achieving a compact layout and helping to reduce the overall footprint of the equipment.

[0044] In some embodiments, the conveyor line 31 includes a first frame 311 and a second frame 312 spaced apart from the first frame 311 along a second direction b. The first frame 311 and the second frame 312 are respectively connected to a first belt conveyor 313 and a second belt conveyor 314. The first belt conveyor 313 and the second belt conveyor 314 jointly support the material 200. The second frame 312 is slidably disposed relative to the first frame 311 along the second direction b to adjust the spacing between the first belt conveyor 313 and the second belt conveyor 314. By adjusting the spacing between the first belt conveyor 313 and the second belt conveyor 314, the conveyor line 31 can be adapted to materials 200 of different sizes, thus allowing for adaptive adjustment according to different sizes of materials 200. Therefore, it can adapt to materials 200 of various specifications, greatly enhancing the flexibility and applicability of the testing device.

[0045] Optionally, such as Figure 4 As shown, the second frame 312 is connected to an adjustment driver 315. The adjustment driver 315 includes a rotary drive 3151, a lead screw 3152 connected to the rotary output end of the rotary drive 3151, and a nut seat 3153 sleeved on and threadedly connected to the lead screw 3152. The second frame 312 is connected to the nut seat 3153. The lead screw 3152 extends along the second direction b. The rotary drive 3151 drives the lead screw 3152 to rotate. The rotational motion of the lead screw 3152 is converted into the linear motion of the nut seat 3153, thereby causing the second frame 312 to slide along the second direction b.

[0046] In addition, among the two conveyor lines 31, the conveyor line 31 farther from the loading platform 10 is equipped with a blocking structure 34. The blocking structure 34 is slidably disposed between the first belt line 313 and the second belt line 314 in the vertical direction c. The blocking structure 34 is used to block the material 200. When the material 200 is conveyed to the position, the blocking structure 34 can slide above the conveying surface 32 of the conveyor line 31 and block the material 200 on the conveyor line 31, thereby blocking the material 200 at a preset position and ensuring that the position of the material 200 after stopping is uniform. Optionally, the blocking structure 34 can be connected to a lifting cylinder 35, which drives the blocking structure 34 to rise and fall.

[0047] In some embodiments, the testing apparatus further includes a barcode scanning structure 50 disposed on the loading platform 10. The barcode scanning structure 50 is used to scan the material 200 located on the loading platform 10 to read the information of the material 200, thereby facilitating subsequent testing of the material 200. Understandably, the material 200 can be equipped with identification codes such as one-dimensional codes, barcodes, and serial numbers to reflect relevant information about the material 200. Once the material 200 is placed on the loading platform 10, the barcode scanning structure 50 immediately and automatically scans the material 200. This information is uploaded to the control system in real time. The control system can automatically associate and bind the material 200 with subsequent test data and configure different test parameters and test schemes for different models of material 200, improving the flexibility of testing. Optionally, the barcode scanning structure 50 is a barcode scanner.

[0048] In some embodiments, such as Figure 3 and Figure 5 As shown, the test assembly 42 includes multiple test elements 421 spaced apart, each of which is used to test the material 200; the test structure 40 also includes a clamping mechanism 43 disposed in the shielding cavity 411, multiple clamping mechanisms 43 are spaced apart and each clamping mechanism 43 corresponds to each test element 421; the clamping mechanism 43 includes a linear adjustment member 431 and a rotating member 432 rotatably connected to the linear adjustment member 431, the test element 421 is connected to the rotating member 432, the linear adjustment member 431 is used to drive the rotating member 432 to move in a straight line to adjust the position of the test element 421, and the rotating member 432 is used to drive the test element 421 to rotate around a preset axis to adjust the orientation of the test element 421 relative to the material 200.

[0049] Understandably, when material 200 is a laptop computer, test element 421 is a coupling antenna. The antenna of a laptop computer is usually hidden inside the chassis. By driving the rotating element 432 and test element 421 to move synchronously in a straight line through the linear adjustment element 431, the test element 421 can be accurately positioned to the optimal coupling position of the laptop's built-in antenna. Then, by adjusting the orientation of the test element 421 through the rotating element 432, the test element 421 can be further matched with the laptop's antenna, thereby improving the accuracy and consistency of the test.

[0050] Optionally, the linear adjustment member 431 includes a horizontal bar 4311 extending along a first direction a, a first connecting block 4312 slidably connected to the horizontal bar 4311 along the first direction a, a vertical bar 4313 connected to the first connecting block 4312 and extending along a vertical direction c, and a second connecting block 4314 slidably connected to the vertical bar 4313 along a vertical direction c. The rotating member 432 is rotatably connected to the second connecting block 4314. Furthermore, the horizontal bar 4311, the vertical bar 4313, and the second connecting block 4314 are provided with scales, thereby facilitating adjustment according to the scales and improving the consistency and accuracy of the adjustment.

[0051] In some embodiments, the test structure 40 further includes a router shielding box 45, which contains a router. An RF cable is connected to the router's RF interface, and the other end of the RF cable extends out of the shielding box 45 and connects to an RF link consisting of an attenuator, a power divider, and a combiner. The final output of this RF link is connected via a cable to a coupling antenna placed inside the enclosure 41. When a laptop is placed inside the enclosure 41, the coupling antenna is close to the laptop, and the laptop receives a Wi-Fi signal from the router, thus forming a communication loop. Optionally, the support platform 44 inside the enclosure 41 is spaced apart from the bottom wall of the enclosure 41. When a coupling antenna located below the laptop needs to be configured, the space between the support platform 44 and the bottom wall of the enclosure 41 can be reserved for the placement of the coupling antenna.

[0052] In some embodiments, multiple test structures 40 are arranged at intervals along a first direction a, and each test structure 40 arranged at intervals along the first direction a corresponds to the same conveying structure 30. The conveying structure 30 is used to move the material 200 to any of the test structures 40. Thus, one set of conveying structures 30 can sequentially or distribute the material 200 to multiple test structures 40. When one test structure 40 is undergoing testing, the conveying structure 30 can continue to feed other idle test structures 40, realizing a linear expansion of testing capacity and greatly improving production efficiency.

[0053] In some embodiments, such as Figure 1As shown, the testing device is provided with a material unloading station 500, a material loading station 300, a testing station 400, and a material unloading station 500 arranged sequentially along the first direction a. The material unloading station 500 is provided with a discharge conveyor line 80 and a material unloading platform 70 that slides along the vertical direction c. The material unloading platform 70 slides to dock with any of the conveying structures 30 and receives the material 200 after testing. The material unloading platform 70 moves the material 200 to the discharge conveyor line 80. The discharge conveyor line 80 receives the material 200 at the material unloading platform 70 and unloads the material 200.

[0054] Understandably, both the loading platform 10 and the unloading platform 70 connect to the conveying structures 30 at different heights by sliding vertically in the direction c, making the flow of material 200 continuous. The material 200 that has completed testing is directly transported from the conveying structure 30 to the unloading station 500, where it is received by the unloading platform 70 and flows to the next process via the discharge conveyor line 80. This avoids the interruptions and waiting time caused by manual intervention, handling, or scheduling of transfer carts in the traditional method, making the flow of material 200 smooth. Furthermore, it eliminates the need to configure an unloading robot or conveyor line for each conveying structure 30, thereby saving space and cost.

[0055] The present invention also proposes a laptop computer production line, which includes a testing device. The specific structure of the testing device is as described in the above embodiments. Since this laptop computer production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0056] In summary, when the testing device of this application is in use, the loading platform 10 receives the material 200 to be tested at the loading station 300 and moves the material 200 to any of the conveying structures 30. After receiving the material from the loading platform 10, the conveying structure 30 moves the material 200 to the corresponding testing structure 40. The transfer structure 20 receives the material 200 from the conveying structure 30 and conveys the material 200 to the shielding cavity 411. The testing component 42 in the shielding cavity 411 tests the material 200. The shielding cavity 411 constructs an independent and isolated electromagnetic environment for the material 200, effectively shielding external electromagnetic interference, thereby greatly improving the accuracy of the test. Furthermore, by arranging multiple layers of conveying structures 30 and multiple layers of testing structures 40 at intervals along the vertical direction c, multiple materials 200 to be tested can be transported in parallel to different testing structures 40 for synchronous testing, which greatly shortens the testing time and improves the testing efficiency.

[0057] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
