Description

Technical Field

[0001] The present invention relates to the technical field of communication and navigation testing, and particularly to a communication and navigation testing device and a communication and navigation testing method for powering on a tablet computer. Background Art

[0002] In precision electronic processing and manufacturing, optical component production testing, and consumer electronics production testing, it is necessary to detect the conductivity of product feature positions, such as the conductivity between components and the conduction situation between connectors. Currently, a multimeter is used to detect the positions to be detected. Two probe needles need to be respectively contacted with the points to be measured, and the operation steps are cumbersome, and the detection results are not intuitive, and the detection efficiency is low. In the prior art, the method for testing the conduction state is relatively complex. Since the contact points of the terminals are relatively small, and very careful operation is required to simultaneously contact two or more contact points of the connected terminals, such detection efficiency is very low, and the measurement accuracy is not high, and test errors are likely to occur.

[0003] Chinese Patent No. CN214473855U discloses a conduction testing device, including a top plate, a first mounting plate, and a second mounting plate. A second cylinder is installed below the first mounting plate, and a flat plate is arranged below the second cylinder. An installation block is fixed above the second mounting plate, and a flat plate and a nylon plate are installed above the installation block, and the nylon plate is located inside the support block. A guide post is installed below the top plate, and the guide post is located outside the spring needle. A guide sleeve is arranged inside the bottom plate. A first cylinder is installed above the second mounting plate, and one end of the first cylinder is connected to a support plate. In this conduction testing device, there are a top plate and a spring needle. When the top plate moves down, the spring needle inside the top plate will press on the surface of the workpiece, and the probe installed on the top plate contacts the workpiece terminal to connect the current. The current flows through the spring needle on the top plate, through the terminal on the workpiece, and then flows out through the copper inlay needle installed inside the bottom plate to complete the product conduction test.

[0004] Since the above technical solution can only be targeted at a single product for each test, the overall test production capacity is still limited by the one-by-one test mode. Each product test process requires waiting, resulting in a long test time interval and being difficult to meet the rapid test requirements of a large-scale production line. Secondly, when manually operating to place the detection product into the detection device, the hands of the staff will enter the pressing area inside the detection device. During the frequent operation of the test device, it is easy to cause accidental injuries to the hands due to fatigue or operation errors, and there are certain safety hazards.

[0010] Preferably, the correction and positioning device includes a limit docking frame slidably installed on the fixed mounting frame. Multiple docking insertion holes are provided on the limit docking frame, and the docking insertion holes correspond to the positioning docking shafts one by one. The correction and positioning device also includes a first linear driver for driving the telescopic movement of the limit docking frame.

[0011] Preferably, the flipping fixture includes a limiting placement plate installed on a rotating mounting plate.

On both sides of the limiting placement grooves, there are also limiting sliding rails. A flipping clamping mechanism is installed on the limiting sliding rails. The limiting placement plate is also provided with a plurality of detection indicator lights, and the detection indicator lights correspond to the limiting placement grooves one by one.

[0012] Preferably, the flipping clamping mechanism includes a plurality of telescopic clamping strips installed in the limiting sliding rails.

[0017] S2. Subsequently, start the positioning flipping seat and drive the flipping fixture to rotate precisely.

[0018] S3. Through the rotation of the flipping fixture, precisely rotate the flat panel to be tested directly above the stable docking detection seat, ensuring that the relative position between the flat panel and the stable docking detection seat is accurate. At the same time, rotate the flat panel that has completed the test to the top position of the flipping fixture for subsequent removal.

[0019] S4. Control the multi-stage lifting platform to rise, so that the stable docking detection seat approaches and pre-contacts the flat plate to be tested for position verification.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. Through the combination of the multi-stage lifting platform and the stable docking detection seat, the present invention realizes the synchronous support and movement of multiple test samples, significantly improving the test production capacity. The lifting function of the multi-stage lifting platform allows for adaptive adjustment of test samples with different heights and types, while the equidistant distribution of the stable docking detection seats ensures that multiple test samples can simultaneously conduct physical contact and electrical connection tests, thus effectively shortening the test time interval and meeting the rapid test requirements of large-scale production lines.

[0023] 2. Through the combined application of the positioning flipping seat and the flipping fixture, the present invention realizes the automatic feeding and discharging of test samples, further improving the test efficiency. The positioning flipping seat rotates to flip the test sample from the top to the bottom for testing, eliminating the need for manual placement, reducing manual intervention, and lowering the risk of accidental injury caused by operation errors. At the same time, the design of the limit placement groove on the flipping fixture ensures the accurate positioning and stability of the test sample during the test, improving the accuracy and reliability of the test.

[0024] 3. Through the configuration of the transparent shielding cover and the safety sensor at the material feeding port on the top of the shielding cabinet, the present invention effectively guarantees the safety during the operation process. The signal indicating that the transparent shielding cover is closed in place is transmitted to the detection controller through the safety sensor. Only when the shielding cover is closed and safe can the test equipment be started, thus preventing the staff from directly touching the pressing area inside the test equipment with both hands during the operation and reducing the risk of accidental injury. In addition, the real-time monitoring and control function of the detection controller enables the staff to always master the operating status and test results of the test equipment, further improving the safety and efficiency of production.

[0037] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0038] See Figures 1 to 10 As shown, a communication and conduction test device includes a safety communication and conduction detection device installed inside the shielding cabinet 5. The safety communication and conduction detection device includes a multi-stage lifting platform 4, a stable docking detection seat 1, a positioning and flipping seat 2, and a flipping and fixing tool 3. The multi-stage lifting platform 4 is fixedly installed inside the shielding cabinet 5, and the lifting end of the multi-stage lifting platform 4 extends vertically upward. There are multiple stable docking detection seats 1, and they are evenly distributed at the lifting end of the multi-stage lifting platform 4. The detection end of the stable docking detection seat 1 extends vertically upward. The positioning and flipping seat 2 is installed on the top of the multi-stage lifting platform 4, and the movable end of the positioning and flipping seat 2 is located directly above the stable docking detection seat 1. There are multiple flipping and fixing tools 3, and they are symmetrically installed on the upper and lower sides of the positioning and flipping seat 2. There are multiple limit placement grooves 311 on the flipping and fixing tool 3, and the limit placement grooves 311 correspond one-to-one with the detection ends of the stable docking detection seats 1, and the limit placement grooves 311 match the shape of the test product.

[0039] The multi-stage lifting platform 4 is fixedly installed inside the shielding cabinet 5, and its lifting end extends vertically upward, used to support and move the stable docking detection seat 1 to different working heights. The design of the multi-stage lifting platform 4 allows for fine height adjustment to accommodate test samples of different sizes and types.

[0040] Multiple stable docking detection seats 1 are provided and evenly distributed on the lifting end of the multi-stage lifting platform 4. The detection end of each stable docking detection seat 1 extends vertically upward, used to make physical contact and electrical connection with the test sample, so as to perform tests. The design of the stable docking detection seat 1 ensures the stability and accuracy when docking with the test sample.

[0041] The positioning and flipping seat 2 is installed on the top of the multi-stage lifting platform 4, and its movable end is directly above the stable docking detection seat 1. The positioning and flipping seat 2 flips the flipping fixture 3 and the test sample on it from the top to the bottom through a rotating action, so as to realize the loading and unloading of continuous test samples.

[0042] Multiple flipping fixtures 3 are provided and symmetrically installed on the upper and lower sides of the positioning and flipping seat 2. Each fixture is provided with multiple limit placement grooves 311. The limit placement grooves 311 correspond one-to-one with the detection ends of the stable docking detection seats 1 and are shaped to match the test sample, so as to ensure the positioning and stability of the test sample during the test.

[0043] The top of the shielding cabinet 5 is provided with a feeding port. A transparent shielding cover 51 and a safety sensor are provided at the feeding port. A detection controller 52 is also installed on the shielding cabinet 5. The feeding port facilitates the staff to place the test sample. A transparent shielding cover 51 and a safety sensor are installed at the feeding port. When the transparent shielding cover 51 is closed in place, the safety sensor emits a signal to allow the test equipment to start. This ensures the safety during the operation process and prevents accidental injuries caused by operation errors. The detection controller 52 is used to monitor and control the operating status of the test equipment, including the test progress, test results, etc., facilitating the staff to grasp the test situation in real time.

[0044] The staff member opens the transparent shielding cover 51 and sequentially places multiple test samples into the limit placement groove 311 of the flipping fixture 3. After closing the transparent shielding cover 51, the safety sensor confirms that the shielding cover is closed in place, and the staff member activates the positioning flipping base 2. The positioning flipping base 2 drives the flipping fixture 3 to rotate, turning the test sample to be tested to directly above the stable docking detection seat 1, and at the same time turning the tested test sample to the top to be taken out. The multi-stage lifting platform 4 rises, causing the stable docking detection seat 1 to pre-contact the test sample to be tested for position calibration. If the position is correct, the lifting platform continues to rise until the detection end is in close contact with the test sample, and power is supplied for testing. During this period, the staff member can open the transparent shielding cover 51 to place a new test sample into the flipping fixture 3 at the top or take out the tested test sample. By repeating the above steps, continuous cyclic testing is achieved, reducing the detection interval time, improving work efficiency, and at the same time preventing the staff member's hands from directly contacting the inside of the testing equipment, thus enhancing production safety.

[0045] See Figures 2 to 6 As shown, the stable docking detection seat 1 includes a limit mounting seat 11 installed on the multi-stage lifting platform 4. Inside the limit mounting seat 11, there is a limit mounting rail. On both sides of the limit mounting rail, there are mounting clamping rails 112. Inside the mounting clamping rails 112, a limit clamping joint 113 is slidably installed. Between the limit clamping joint 113 and the mounting clamping rails 112, a first pressing spring 111 is installed. Inside the limit mounting rail, a contact detection seat 12 is slidably installed.

[0046] The limit mounting rail provided inside the limit mounting seat 11 is used to guide the sliding insertion of the contact detection seat 12, ensuring that the contact detection seat 12 can move along a predetermined trajectory. The mounting clamping rails 112 are provided on both sides of the limit mounting rail, and a limit clamping joint 113 is slidably installed inside them. A first pressing spring 111 is installed between the limit clamping joint 113 and the mounting clamping rails 112. The elastic force of the spring keeps the limit clamping joint 113 in a clamped state, thus effectively restricting the position of the contact detection seat 12 in the limit mounting rail and preventing the contact detection seat 12 from moving.

[0047] The contact detection seat 12 is used to dock with the test sample and perform testing. When the multi-stage lifting platform 4 raises the stable docking detection seat 1 to the position where it contacts the test sample, the contact detection seat 12 will dock and contact the test sample, thereby performing corresponding test operations.

[0048] When the contact detection seat 12 malfunctions or needs maintenance, the staff can cancel the limit on the contact detection seat 12 by toggling the limit card joint 113 to slide and adjust it in the installation card rail 112. Once the limit card joint 113 is released from the clamped state, the staff can quickly remove the problematic contact detection seat 12 from the limit installation rail and perform replacement or repair operations. This not only improves production efficiency but also ensures the stability and reliability of the testing equipment.

[0049] See Figures 4 to 7 As shown, the contact detection seat 12 includes a limit mounting plate 121. Multiple limit holes 1211 are provided on the limit mounting plate 121. A pressure detector 124 is installed at the bottom of the limit hole 1211. Multiple test pins 1212 are also installed on the limit mounting plate 121. Above the limit mounting plate 121, a contact test tool 122 is installed. A sliding guide post is provided at the bottom of the contact test tool 122, and the sliding guide post is slidably connected to the limit hole 1211. A second push spring 123 is installed between the sliding guide post and the pressure detector 124. The contact test tool 122 is also provided with an insertion hole 1221, and the insertion hole 1221 corresponds to the test pin 1212 one by one.

[0050] Multiple limit holes 1211 are provided on the limit mounting plate 121, and pressure detectors 124 are installed at the bottoms of the limit holes 1211 for real-time monitoring of pressure changes. In addition, multiple test pins 1212 are fixed on the limit mounting plate 121 for performing specific test operations. Above the limit mounting plate 121, a contact test tool 122 is installed. A sliding guide post is provided at the bottom of the contact test tool 122, and the sliding guide post is slidably connected to the limit hole 1211, ensuring the stable movement of the contact test tool 122 in the vertical direction. At the same time, a second push spring 123 is installed between the sliding guide post and the pressure detector 124, providing an appropriate pre-tightening force and buffering effect for the contact test tool 122. The contact test tool 122 is also provided with insertion holes 1221 corresponding to the test pins 1212 one by one for the test pins 1212 to pass through during the test process.

[0051] During the test process, when the multi-stage lifting platform 4 stably docks the detection seat 1 to the position in contact with the test product, the contact test tool 122 first contacts the test product. If the contact test tool 122 can smoothly enter the interior of the test product, it indicates that the test product has been correctly placed in the designated position and subsequent tests can be carried out. At this time, the pressure detector 124 will monitor the pressure value of the second push spring 123 to ensure that the fit between the contact test tool 122 and the test product is within the normal range.

[0052] If the contact test tool 122 fits stably with the test article and the pressure detector 124 does not detect abnormal pressure, the multi-stage lifting table 4 will continue to drive the contact detection seat 12 to rise. During this process, the second push spring 123 will be compressed, enabling the test needle 1212 on the limit mounting plate 121 to smoothly pass through the insertion hole 1221 on the contact test tool 122 and directly contact the test article. Subsequently, various performance tests are carried out on the test article through the test needle 1212 to complete the entire test process.

[0053] See Figure 2 , Figure 8 and Figure 9 As shown in

[0054] A rotating mounting plate 22 is rotatably mounted on the fixed mounting frame 21. Multiple positioning and docking shafts 23 are provided on the side of the rotating mounting plate 22. The positioning and docking shafts 23 are used to dock with the correction and positioning device 25 to ensure the stability and accuracy during the flipping process. When the rotating mounting plate 22 rotates to a predetermined position under the drive of the rotation drive 24, the correction and positioning device 25 will immediately intervene to precisely correct and position and fix the positioning and docking shafts 23, thereby ensuring the stability and accuracy of the flipping fixture 3 during the flipping process.

[0055] See Figures 1 to 10 As shown in

[0056] When the rotating mounting plate 22 completes the flipping action and reaches the predetermined position under the drive of the rotation drive 24, the positioning and docking shafts 23 move accordingly. At this time, the first linear drive 252 is activated to drive the limit docking frame 251 to slide along the fixed mounting frame 21 and move towards its corresponding positioning and docking shaft 23. As the limit docking frame 251 approaches, the docking jacks 2511 gradually align with and contact the positioning and docking shafts 23 until they are completely nested. The tight fit between the docking jacks 2511 and the positioning and docking shafts 23 effectively ensures the stability and accuracy of the rotating mounting plate 22 after flipping to the predetermined position, and further guarantees the position accuracy and stability of the entire flipping fixture 3 during the flipping process.

[0057] SeeFigure 2 , Figure 8 and Figure 10 As shown in Figure 2 , Figure 8 and Figure 10 , the flipping fixture 3 includes a limit placement plate 31 mounted on the rotating mounting plate 22. A plurality of limit placement grooves 311 are provided on the limit placement plate 31. Inside the limit placement grooves 311, there are correction guiding blocks 34, suction cups 33 and fitting sensors 32. Limit sliding rails are also provided on both sides of the limit placement grooves 311. A flipping clamping mechanism 36 is mounted on the limit sliding rails. A plurality of detection prompt lights 35 are also provided on the limit placement plate 31, and the detection prompt lights 35 correspond to the limit placement grooves 311 one by one.

[0058] First, the test piece is placed in the limit placement grooves 311 on the limit placement plate 31. The correction guiding blocks 34 inside the limit placement grooves 311 are customized according to the shape of the test piece and are used to guide the test piece to be correctly placed into the grooves, effectively avoiding the situation of misplacement. When the test piece is placed in the limit placement grooves 311, the fitting sensors 32 are immediately activated to sense whether the test piece has been correctly placed in the designated position, ensuring the accurate docking of the test piece and the detection end. At the same time, the suction cups 33 also start to work, generating suction force to adsorb the test piece placed in the designated position. This suction force not only helps to maintain the stability of the test piece during flipping but also prevents the displacement of the test piece caused by vibration or external interference.

[0059] When the test piece is stably placed and adsorbed, the rotating mounting plate 22 starts to rotate under the drive of the rotation driver 24. At this time, the flipping clamping mechanism 36 is triggered, moves along the limit sliding rails, and clamps the test piece to ensure that the test piece will not fall off or shift during flipping.

[0060] During the flipping process, the detection prompt lights 35 start to work. The detection prompt lights 35 correspond to the limit placement grooves 311 one by one and are used to display the test status of the test piece at the corresponding position. When the test piece is being tested, the corresponding detection prompt light 35 will light up a specific color to remind the staff of the current status of the test piece.

[0061] See Figures 8 to 10 As shown in Figures 8 to 10 , the flipping clamping mechanism 36 includes a plurality of telescopic clamping strips 361 mounted in the limit sliding rails. A pushing telescopic rod 362 is provided beside the telescopic clamping strips 361. The pushing telescopic rod 362 is slidably connected to the limit placement plate 31. A pressing ball 3621 is provided at the end of the pushing telescopic rod 362 away from the limit placement plate 31. A third pushing spring 363 is installed between the pushing telescopic rod 362 and the limit placement plate 31. A synchronous connecting rod 364 is installed between the pushing telescopic rod 362 and the telescopic clamping strips 361. The flipping clamping mechanism 36 also includes a rotation control disk 365 mounted on the side of the fixed mounting frame 21. A contact surface is provided on the side of the rotation control disk 365, and a release plane 3652 and a pressing convex surface 3651 are provided on the contact surface.

[0062] The pushing telescopic rod 362 is slidably connected to the limiting placement plate 31, and a pressing ball 3621 is provided at one end of the pushing telescopic rod 362 away from the limiting placement plate 31 to reduce the friction force with the rotation control disc 365. A third pushing spring 363 is installed between the pushing telescopic rod 362 and the limiting placement plate 31 to provide the necessary reset force. In addition, the pushing telescopic rod 362 and the telescopic clamping strip 361 are connected by a synchronous connecting rod 364 to ensure their synchronous movement. The flipping clamping mechanism 36 further includes a rotation control disc 365 installed on the side of the fixed mounting frame 21, with a contact surface on its side, and a release plane 3652 and a pressing convex surface 3651 are respectively provided on the contact surface for controlling the movement state of the pushing telescopic rod 362.

[0063] In the initial state, when the flipping fixture 3 is located above the rotating mounting plate 22, the pressing ball 3621 of the pushing telescopic rod 362 contacts the pressing convex surface 3651 of the rotation control disc 365, causing the pushing telescopic rod 362 to compress the third pushing spring 363 and keeping the telescopic clamping strip 361 in an expanded state through the synchronous connecting rod 364. At this time, the telescopic clamping strip 361 does not clamp the test piece.

[0064] When the test piece is correctly placed in the limiting placement groove 311 on the limiting placement plate 31 and the rotating mounting plate 22 starts to rotate driven by the rotation driver 24, the limiting placement plate 31 and all components thereon, including the pushing telescopic rod 362, will rotate synchronously. As the pushing telescopic rod 362 disengages from the pressing convex surface 3651 and rotates to the position of the release plane 3652, the elastic force of the third pushing spring 363 will push the pushing telescopic rod 362 towards the rotation control disc 365 until the pressing ball 3621 contacts the release plane 3652. During this process, the movement of the pushing telescopic rod 362 drives the telescopic clamping strip 361 to contract synchronously through the synchronous connecting rod 364, thereby clamping and fixing the test piece in the limiting placement groove 311. It ensures the stability and safety of the test piece during the flipping process, avoids the displacement of the test piece caused by vibration or external interference, and thus guarantees the accuracy and reliability of the test.

[0065] See Figure 2 and Figure 3 As shown in, the multi-stage lifting platform 4 includes a mounting bottom plate 41 installed inside the shielding cabinet 5, a plurality of lifting guide columns 42 are installed on the mounting bottom plate 41, a lifting push plate 43 is installed on the lifting guide columns 42, a second linear driver 44 is also installed on the mounting bottom plate 41, the output end of the second linear driver 44 is connected to the lifting push plate 43, and a blocking device 45 is installed beside the lifting push plate 43.

[0066] A plurality of lifting guide posts 42 are fixed on the mounting base plate 41, and the lifting guide posts 42 provide a stable lifting track for the lifting push plate 43. In addition, a second linear driver 44 is also installed on the mounting base plate 41, and its output end is directly connected to the lifting push plate 43, which is used to drive the lifting push plate 43 to perform precise vertical movement along the lifting guide posts 42. In order to ensure the accuracy and stability of the lifting push plate 43 during the movement, a blocking device 45 is also installed on the side of the lifting push plate 43. The blocking device 45 is used to limit the movement range of the lifting push plate 43 to ensure that it can accurately stay at the predetermined position after each lifting operation.

[0067] During the working process, when it is necessary to push the stable docking detection seat 1 to dock with the test article, the second linear driver 44 pushes the lifting push plate 43 to rise or fall smoothly along the lifting guide posts 42. Since there is a fixed connection relationship between the lifting push plate 43 and the stable docking detection seat 1, the movement of the lifting push plate 43 will directly cause the synchronous movement of the stable docking detection seat 1.

[0068] During the rising process of the lifting push plate 43, when the lifting push plate 43 reaches the predetermined height, the blocking device 45 restricts the further movement of the lifting push plate 43. At this time, the contact test tool 122 on the stable docking detection seat 1 will make a preliminary contact with the test article. This is to verify whether the test article has been correctly placed at the designated position. If the contact test tool 122 can smoothly enter the interior of the test article, it indicates that the position of the test article is correct and subsequent test operations can be carried out.

[0069] In order to ensure that the fit between the contact test tool 122 and the test article is within the normal range, the pressure value of the second push spring 123 is monitored by the pressure detector 124. If the contact test tool 122 is stably fitted with the test article and the pressure detector 124 does not detect abnormal pressure, the blocking device 45 will release the limit on the lifting push plate 43 and allow it to continue rising. During the continuous rising process of the lifting push plate 43, the second push spring 123 will be gradually compressed, thereby pushing the test needle 1212 on the limit mounting plate 121 to pass through the insertion hole 1221 on the contact test tool 122 and make direct contact with the test article. The multi-stage pressing of the test article is realized, ensuring good contact between the test needle 1212 and the test article, thereby improving the accuracy and reliability of the test.

[0070] See Figure 2 and Figure 3 As shown, the blocking device 45 includes a mounting bracket 451 installed inside the shielding cabinet 5. A telescopic blocking frame 452 is slidably installed on the mounting bracket 451. A third linear driver 453 is also installed on the mounting bracket 451, and the output of the third linear driver 453 is connected to the telescopic blocking frame 452.

[0071] In the work process, the third linear driver 453 is responsible for driving the telescopic blocking frame 452 to perform precise telescopic movement. When the lifting push plate 43 moves along the lifting guide post 42 to a predetermined height, the third linear driver 453 is activated to drive the telescopic blocking frame 452 to extend, so as to block the further movement of the lifting push plate 43. This operation ensures that the lifting push plate 43 and the connected stable docking detection seat 1 can accurately stop at the predetermined position, thereby realizing the preliminary contact test.

[0072] During the contact test, if the contact test tool 122 is stably attached to the test item and the pressure detector 124 does not detect abnormal pressure, the third linear driver 453 is activated again to drive the telescopic blocking frame 452 to contract, releasing the limit on the lifting push plate 43. At this time, the lifting push plate 43 can continue to move along the lifting guide post 42 to perform subsequent test operations.

[0073] A conduction test method for a conduction test device for a flat panel to be powered on includes the following steps:

[0074] S1. PreciseIy place multiple flat panels 6 to be tested into the limit placement slots 311 of the flipping fixture 3 in a predetermined order, ensuring that each flat panel 6 is stably and accurately positioned at the predetermined position.

[0075] S2. Subsequently, start the positioning flipping base 2 to drive the flipping fixture 3 to perform precise rotation.

[0076] S3. Through the rotation of the flipping fixture 3, precisely rotate the flat panel 6 to be tested directly above the stable docking detection seat 1, ensuring the accurate relative position between the flat panel 6 and the stable docking detection seat 1. At the same time, rotate the flat panel 6 that has completed the test to the top position of the flipping fixture 3 for subsequent removal.

[0077] S4. Control the multi-stage lifting platform 4 to rise, so that the stable docking detection seat 1 approaches and preliminarily contacts the flat panel 6 to be tested for position verification. If the verification result shows that the position of the flat panel 6 is correct, continue to control the lifting platform to rise until the detection end is in close contact with the flat panel 6, and then start the power-on test program.

[0078] S5. While the power-on test is in progress, the staff can continue to place new flat panels 6 to be tested at the position on the top of the flipping fixture 3 or remove the flat panels 6 that have completed the test. After completing the replacement of the flat panel 6, repeat steps S1 to S4 to achieve continuous circulation of the test process and improve the test efficiency.
