Abstract
Description
Technical Field
[0001] This application relates to the field of testing technology, and in particular to a testing fixture for decorative parts. Background Technology
[0002] An antenna is a component used for transmitting or receiving radio waves and can be installed inside electronic devices such as mobile phones. An antenna completes the signal transmission and reception process by converting the circuit signal energy output from the transmitter into electromagnetic waves for radiation, or by converting spatial electromagnetic wave signals into circuit signal energy for transmission to the receiver. As electronic devices need to meet increasingly diverse frequency band and functional requirements, there is a need to find more ways to install antennas within the limited space inside these devices. With continuous advancements in manufacturing processes, a technology that directly integrates decorative components mounted on the back cover of electronic devices as antennas is gradually being applied.
[0003] In related technologies, decorative components need to be assembled onto electronic devices to test antenna performance. This is primarily to simulate the actual operating environment of the electronic device using the complete unit, and then use coupling testing to test the radio frequency performance of the entire unit in a wireless environment. This determines whether the antenna performance of the decorative component is good. If the antenna performance is poor, the entire unit needs to be disassembled and reassembled with other antennas. As can be seen, coupling testing can only test the performance of decorative components on the assembled unit, and cannot test their performance separately before assembly. This reduces both the efficiency of testing the performance of decorative components and the efficiency of assembling a good unit. Summary of the Invention
[0004] In view of this, embodiments of this application provide a decorative component testing fixture that can perform performance testing on the decorative component under test, which serves as an antenna, thereby improving the efficiency of performance testing of the decorative component under test.
[0005] This application provides a decorative part testing fixture, which includes a bearing mechanism, a clamping mechanism, and a testing mechanism.
[0006] The bearing mechanism has a bearing surface, and the bearing surface is provided with a test area suitable for placing the decorative part to be tested;
[0007] The testing mechanism includes a power supply test line, a grounding test line, a power supply probe, and at least one grounding probe.

One end of the grounding probe is exposed in the testing area, and the other end is electrically connected to the grounding test line. The power supply test line and the grounding test line are adapted to be electrically connected to a network analyzer.
[0008] At least a portion of the clamping mechanism can move toward and away from the bearing surface.
[0009] Optionally, the test area has multiple test holes, and the power supply probe and the at least one grounding probe are respectively disposed in one of the test holes, wherein at least three of the multiple test holes can form the three vertices of a triangle.

The power supply circuit is electrically connected to the power supply probe and the power supply test line, respectively, and the grounding circuit is electrically connected to at least one of the grounding probes and the grounding test line, respectively.
[0012] Optionally, the bearing mechanism includes a bearing member and a positioning member, the bearing member is detachably mounted on the positioning member, the side of the bearing member facing away from the positioning member is the bearing surface, and the circuit board is mounted on the positioning member.
[0013] Optionally, the clamping mechanism includes a bracket, a clamping block, and a driving component;
[0014] The driving component is mounted on the bracket, and the driving end of the driving component is connected to the clamping block to drive the clamping block to move toward and away from the bearing surface.
[0015] Optionally, the clamping block has at least one positioning post on one of its surfaces facing the bearing surface and at least one positioning groove on the other surface. When the clamping block moves toward the bearing surface, the positioning post engages with the corresponding positioning groove.
[0016] Optionally, the surface of the clamping block facing the bearing surface is connected to a protrusion.
[0017] Optionally, the decorative part testing fixture further includes a pressure reducing valve mounted on the bracket, the pressure reducing valve being used to control the pressure value applied by the drive to the clamping block.
[0018] Optionally, the decorative component testing fixture further includes an electrical housing, the supporting mechanism is mounted on the top surface of the electrical housing, and a controller is provided inside the electrical housing, the controller being electrically connected to the driving component.
[0019] Optionally, the bracket includes a first support member and a second support member connected together. The two ends of the first support member are respectively connected to the top surface of the electrical chassis and the second support member. The second support member extends away from the first support member and is opposite to the bearing surface. The driving end of the driving member passes through the second support member and is connected to the clamping block.
[0020] The decorative component testing fixture provided in this application includes a support mechanism, a clamping mechanism, and a testing mechanism. By placing the decorative component to be tested, which serves as an antenna, within the testing area on the support surface of the support mechanism, a portion of the clamping mechanism moves towards the support surface, thus clamping the decorative component to be tested into the testing area and positioning it.

Therefore, when the feed test line and the ground test line are connected to a network analyzer, the performance of the decorative component to be tested can be determined by the waveform displayed on the network analyzer. In other words, using the decorative component testing fixture provided in this application, the performance of the decorative component to be tested can be tested separately without assembling it onto an electronic device for testing. This improves the efficiency of testing the performance of the decorative component to be tested as an antenna and also improves the assembly efficiency of good electronic devices.

Detailed Implementation
[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0041] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.
[0042] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0043] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this application provides a decorative part testing fixture, which includes a bearing mechanism 100, a clamping mechanism 200 and a testing mechanism 300.
[0044] The supporting mechanism 100 has a supporting surface 110, and the supporting surface 110 is provided with a test area 111 suitable for placing the decorative part 400 to be tested. At least a portion of the pressing mechanism 200 can move toward and away from the supporting surface 110. Thus, when at least a portion of the pressing mechanism 200 moves toward the supporting surface 110, the decorative part 400 to be tested can be pressed into the test area 111 to fix the decorative part 400 to be tested. It should be noted that the decorative part 400 to be tested in this embodiment is an antenna, and the decorative part 400 to be tested generally has at least one feed point 450 and at least one ground point 460. The decorative part 400 to be tested can generally be assembled with the housing of an electronic device, for example, it can be assembled with the battery cover of an electronic device, and can decorate the image acquisition module on the electronic device, such as decorating the camera. It should be understood that the decorative part 400 to be tested not only serves to decorate the appearance of the electronic device, but also realizes the function of transmitting and receiving signals.
[0045] The test mechanism 300 includes a power supply test line 310, a grounding test line 320, a power supply probe 330, and at least one grounding probe 340. One end of the power supply probe 330 is exposed in the test area 111, and the other end is electrically connected to the power supply test line 310. One end of the grounding probe 340 is exposed in the test area 111, and the other end is electrically connected to the grounding test line 320. The power supply test line 310 and the grounding test line 320 are suitable for electrical connection to the network analyzer 500. It should be noted that the two ends of the power supply probe 330 can be electrically connected to the corresponding power supply point 450 and the power supply test line 310 on the decorative part 400 under test, respectively. At the same time, the two ends of the grounding probe 340 can be electrically connected to the corresponding grounding point 460 and the grounding test line 320 on the decorative part 400 under test, respectively. Therefore, once the power supply test line 310 and the grounding test line 320 are connected to the network analyzer 500, the performance of the decorative component 400 under test can be determined by the waveform displayed on the network analyzer 500.
[0046] In other words, by using the decorative part testing fixture provided in this application embodiment, the performance of the decorative part 400 to be tested can be tested separately without assembling the decorative part 400 to be tested onto the electronic device before testing. This improves the efficiency of testing the performance of the decorative part to be tested as an antenna and also improves the assembly efficiency of good electronic devices.
[0047] The following is in conjunction with the appendix Figures 1 to 9 The various components and functions of the decorative part testing fixture provided in the embodiments of this application will be described in more detail.
[0048] Combination Figure 1 and Figure 3As shown, in some embodiments, the test area 111 has multiple test holes 112, with a feed probe 330 and at least one ground probe 340 respectively passing through one test hole 112. At least three of the multiple test holes 112 can form the three vertices of a triangle. It should be noted that at least a portion of the test decorative element 400 used as an antenna in this embodiment is a metal part, which can generally be triangular, quadrilateral, circular, or polygonal in shape. Such decorative elements typically have a large number of grounding points 460. For example... Figure 3 The decorative part to be tested is roughly square in shape. One side of the square has a power supply point 450 and a grounding point 460, and the other two sides each have a grounding point 460. Multiple test holes 112 are arranged in the above positions so that the positions of the test holes 112 can match the positions of the grounding point 460 and the power supply point 450 on the decorative part 400 to be tested.
[0049] like Figure 5 As shown, in some embodiments, a first limiting component 120 and a second limiting component 130 are installed on the bearing surface 110. The first limiting component 120 includes at least two first limiting blocks 121 arranged opposite each other along a first direction, and the second limiting component 130 includes at least two second limiting blocks 131 arranged opposite each other along a second direction. The two first limiting blocks 121 and the two second limiting blocks 131 enclose a test area 111, wherein the first direction and the second direction intersect. With this configuration, the first limiting blocks 121 and the second limiting blocks 131 can be used to fix the decorative part 400 to be tested, preventing the decorative part 400 to be tested from shifting during the test and affecting the test results, thereby improving the accuracy of the test results.
[0050] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the decorative component 400 to be tested includes a first side 410, a second side 420, a third side 430, and a fourth side 440 connected in sequence. The first side 410 and the third side 430 are arranged opposite to each other, and the second side 420 and the fourth side 440 are arranged opposite to each other. The inner walls of the two first limiting blocks 121 and the inner walls of the two second limiting blocks 131 enclose a test area 111. The inner walls of the two first limiting blocks 121 abut against the first side 410 and the third side 430, respectively, and the inner walls of the two second limiting blocks 131 abut against the second side 420 and the fourth side 440, respectively, thereby stably fixing the decorative component 400 to be tested within the test area 111.
[0051] Combination Figure 1 , Figure 4 and Figure 5As shown, in some embodiments, the first direction and the second direction are perpendicular to each other. This allows the first limiting block 121 and the second limiting block 131 to more comprehensively fix the circumference of the decorative element 400 under test, preventing the decorative element 400 from shifting.
[0052] like Figure 5 As shown, in some embodiments, the first limiting block 121 and the second limiting block 131 are detachably or movably disposed on the bearing surface 110. Therefore, when antenna performance testing is required for decorative parts 400 of different sizes, the positions of the first limiting block 121 and the second limiting block 131 can be adjusted more flexibly, thereby meeting the needs of decorative parts 400 of different sizes and improving the applicability of the decorative part testing fixture.
[0053] Combination Figure 5 As shown, in some embodiments, the supporting mechanism 100 further includes two first driving components (not shown in the figure) and two second driving components (not shown in the figure). The driving end of the first driving component is connected to the corresponding first limiting block 121, and the driving end of the second driving component is connected to the corresponding second limiting block 131. It should be noted that the first driving component and the second driving component can be, for example, a drive motor. The first driving component is used to drive the corresponding first limiting block 121 to move along a first direction, so that the two first limiting blocks 121 move closer to each other or further away from each other. The second driving component is used to drive the corresponding first limiting block 121 to move along a second direction, so that the two second limiting blocks 131 move closer to each other or further away from each other. This allows for more flexible adjustment of the size of the test area 111 to meet the needs of different sized decorative parts 400 to be tested, improving the applicability of the decorative part test fixture.
[0054] Combination Figure 2 and Figure 3 As shown, in some embodiments, the test mechanism 300 further includes a circuit board 350, on which a power supply circuit (not shown) and a grounding circuit (not shown) are provided. The power supply circuit is electrically connected to a power supply probe 330 and a power supply test line 310, respectively, and the grounding circuit is electrically connected to at least one grounding probe 340 and a grounding test line 320, respectively. It should be noted that the circuit board 350 in the embodiments of this application can be, for example, a printed circuit board 350 or a flexible circuit board 350. It should be understood that when the decorative part 400 to be tested has multiple grounding points 460, the input terminal of the grounding circuit can be electrically connected to multiple grounding probes 340 electrically connected to the grounding points 460, and the output terminal of the grounding circuit is electrically connected to the grounding test line 320.
[0055] like Figure 1As shown, in some embodiments, the support mechanism 100 includes a support member 140 and a positioning member 150. The support member 140 is detachably mounted on the positioning member 150. The side of the support member 140 facing away from the positioning member 150 is the support surface 110, and the circuit board 350 is mounted on the positioning member 150. This arrangement facilitates the replacement of the support member 140. It should be noted that each support member 140 can match the size of at least one size of the decorative part 400 to be tested. Because the support member 140 can be flexibly replaced, the decorative part testing fixture can meet the testing needs of more sizes of decorative parts 400 to be tested, thus improving the applicability of the decorative part testing fixture.
[0056] like Figure 1 As shown, in some embodiments, the clamping mechanism 200 includes a bracket 210, a clamping block 220, and a driving member 230. The driving member 230 is mounted on the bracket 210, and its driving end is connected to the clamping block 220 to drive the clamping block 220 to move toward and away from the bearing surface 110. It should be noted that the driving member 230 in this embodiment can be a cylinder or a motor. The bracket 210 not only serves to mount the driving member 230 but also provides support for it, ensuring that when the driving member 230 is started, its output end can more smoothly drive the clamping block 220 to move toward or away from the bearing surface 110. When the clamping block 220 moves toward the bearing surface 110 to its lowest point, it can press against the decorative piece 400 to be tested within the test area 111 to fix the decorative piece 400 to be tested.
[0057] like Figure 7 As shown, in some embodiments, the clamping block 220 has at least one positioning post 221 on its surface facing the bearing surface 110, and the bearing surface 110 has at least one positioning groove 113 on its other surface. When the clamping block 220 moves toward the bearing surface 110, the positioning post 221 engages with the corresponding positioning groove 113. It should be noted that the accompanying drawings of this application illustrate the example of setting a positioning groove 113 on the bearing surface 110 and a positioning post 221 on the clamping block 220. When the positioning post 221 engages with the positioning groove 113, it can be ensured that there is no relative movement between the clamping block 220 and the bearing member 140 during the test, so that the decorative part 400 to be tested can be more stably fixed in the test area 111, thereby avoiding the influence of the accuracy of the test results due to the movement of the decorative part 400 to be tested during the test, that is, improving the accuracy of the test results.
[0058] like Figure 8As shown, in some embodiments, a protrusion 222 is connected to the surface of the clamping block 220 facing the bearing surface 110. It should be noted that when the clamping block 220 moves to its lowest point facing the bearing surface 110, the protrusion 222 abuts against the surface of the decorative piece 400 to be tested facing the clamping block 220. By providing the protrusion 222, the decorative piece 400 to be tested can be more stably fixed.
[0059] like Figure 8 As shown, in some embodiments, the protrusion 222 includes a first protrusion 223 and a second protrusion 224 that are perpendicular to each other. This arrangement ensures that the decorative piece 400 to be tested is fixed in all directions.
[0060] Combination Figure 1 and Figure 6 As shown, in some embodiments, the decorative part testing fixture further includes a pressure reducing valve 600, which is mounted on the bracket 210. The pressure reducing valve 600 is used to control the pressure value applied by the drive member 230 to the clamping block 220. It is understood that by controlling the pressure value applied by the drive member 230 to the clamping block 220, the pressure reducing valve 600 can prevent the drive member 230 from damaging the clamping block 220 or the decorative part 400 to be tested that is against the clamping block 220 due to excessive pressure, and can also prevent the drive member 230 from failing to fix the decorative part 400 to be tested due to insufficient pressure. Simultaneously, it can ensure that the drive member 230 can drive the clamping block 220 to move more smoothly. In other words, the pressure reducing valve 600 can improve the reliability of the decorative part testing fixture provided in this application embodiment.
[0061] like Figure 1 As shown, in some embodiments, the test fixture further includes an electrical enclosure 700. The support mechanism 100 is mounted on the top surface 720 of the electrical enclosure 700. A controller 710 is provided inside the electrical enclosure 700, and the controller 710 is electrically connected to the drive component 230. It should be understood that the electrical enclosure serves not only to support the support mechanism 100, the clamping mechanism 200, and the test mechanism 300, but also to protect the controller 710.
[0062] Combination Figure 1 and Figure 7As shown, in some embodiments, the top surface 720 of the electrical enclosure 700 is provided with a first opening 721, and the electrical enclosure 700 is also provided with a second opening 722. The first opening 721 faces the circuit board 350. The positioning member 150 has a through hole 151. One end of the power supply test line 310 passes through the first opening 721 and the through hole 151 in sequence to be electrically connected to the power supply probe 330, and the other end passes through the second opening 722 and is electrically connected to the network analyzer 500. One end of the grounding test line 320 passes through the first opening 721 and the through hole 151 in sequence to be electrically connected to the grounding probe 340, and the other end passes through the second opening 722 and is electrically connected to the network analyzer 500. It should be noted that the network analyzer 500 can be located outside the electrical enclosure 700. When the grounding test line 320 and the power supply test line 310 are respectively connected to the corresponding interfaces on the network analyzer 500, the network analyzer 500 can display the waveform corresponding to the measured decorative part. It should be understood that when the waveform matches the waveform characteristic of good antenna performance, it indicates that the tested decorative component has good performance; when the waveform does not match the waveform characteristic of good antenna performance, it indicates that the tested decorative component has poor performance. In other words, by testing the decorative component 400 individually, it is possible to quickly distinguish whether the decorative component is good or not. This not only improves the efficiency of performance testing of the decorative component 400, but also facilitates the timely assembly of good decorative components onto electronic devices, thereby improving the assembly efficiency of electronic devices.
[0063] like Figure 6 As shown, in some embodiments, the bracket 210 includes a first support member 211 and a second support member 212 connected together. The two ends of the first support member 211 are connected to the top surface 720 of the electrical housing 700 and the second support member 212, respectively. The second support member 212 extends away from the first support member 211 and faces the bearing surface 110. The driving end of the drive member 230 passes through the second support member 212 and is connected to the clamping block 220. It should be noted that the pressure reducing valve 600 can be mounted on the first support member 211. The first support member 211 and the second support member 212 can provide support to the drive member 230 and the pressure reducing valve 600.
[0064] Combination Figure 1 and Figure 6As shown, in some embodiments, the clamping mechanism 200 further includes a connector 240, with its two sides connected to the drive end of the drive member 230 and the clamping block 220, respectively. When the drive end of the drive member 230 extends or retracts, it can push the connector 240 and the clamping block 220 to move synchronously toward or away from the bearing surface 110. One of the surfaces of the connector 240 facing the first support member 211 and the first support member 211 facing the connector 240 is provided with at least one slide rail 241, and the other is provided with at least one slide groove 213. The slide rail 241 can move within the corresponding slide groove 213, wherein the extension direction of the slide rail 241 and the extension direction of the slide groove 213 are both parallel to the moving direction of the clamping block 220. It is understood that the cooperation of the slide rail 241 and the slide groove 213 ensures that the clamping block 220 can move more smoothly along the moving direction, preventing the clamping block 220 from deviating during movement. This ensures that the clamping block 220 can accurately press down on the decorative part 400 to be tested within the test area 111, thereby improving the reliability of the decorative part test fixture.
[0065] Combination Figure 1 and Figure 6 As shown, in some embodiments, the connector 240 includes a first connecting plate 242 and a second connecting plate 243 connected together. The first connecting plate 242 is perpendicular to the moving direction of the clamping block 220, and the second connecting plate 243 is perpendicular to the first connecting plate 242. The two sides of the first connecting plate 242 are respectively connected to the driving end of the driving member 230 and the clamping block 220. The surface of the second connecting plate 243 facing the first support member 211 is provided with a slide rail 241 or a slide groove 213. A limiting member 244 is installed on the surface of the first connecting plate 242 facing the driving member 230, and the limiting member 244 is provided with a slot 245. The driving end of the driving member 230 is located in the slot 245 and fixed to the first connecting plate 242. It should be noted that the first connecting plate 242 and the limiting member 244 can be fixedly connected by bolts or other fasteners. Understandably, the slot 245 can limit the drive end of the drive component 230, ensuring that the drive end of the drive component 230 can move smoothly in the same direction, thereby driving the clamping block 220 to move smoothly in the same direction, avoiding the clamping block 220 from shifting, and further improving the reliability of the decorative part test fixture.
[0066] As can be seen from the above, the decorative part testing fixture provided in this application embodiment has high reliability and applicability. It can stably fix the decorative part 400 to be tested and perform separate testing on the performance of the decorative part 400 used as an antenna.
