[0048] Reference Figure 1 The component 100 (e.g., an antenna) includes a main body 110, a flexible circuit board 120, and a docking portion 130. The flexible circuit board 120 includes a first power-carrying section 121, a bending portion 123, and a flexible circuit board 122. The bending portion 123 is connected between the first power-carrying section 121 and the flexible circuit board 122. The main body 110 is connected to the first power-carrying section 121, and the docking portion 130 is connected to the flexible circuit board 122. The docking portion 130 is used to be plugged into and connected to the plug-in portion 510 of the test module 500, so that the test module 500 can test the main body 100.

[0049] According to the first aspect of the present invention, a correction structure 320 is disclosed for correcting the body 100. Figures 2 to 4 The correction structure 320 includes a lower jig assembly 300 and an upper jig assembly 400. The lower jig assembly 300 includes a lower jig 310, a correction structure 320 and a first elastic member 330. The lower jig 310 is used to position the body 100. The correction structure 320 is slidably set on the lower jig 310. The sliding direction of the correction structure 320 is set to the extension direction of the flexible circuit board 122, and it switches between the first position and the second position. The first elastic member 330 is disposed between the lower jig 310 and the correction structure 320 and is used to reset the correction structure 320 from the second position to the first position. The correction structure 320 has a correction surface 3222. When the correction structure 320 is in the second position, the correction surface 3222 is used to abut against the end of the flexible circuit board 122 away from the bent portion 123 to maintain the flexible circuit board 122 in the docking position. The upper jig assembly 400 includes an upper jig 410 and a pusher 420. The upper jig 410 is used to load the test module 500. The pusher 420 is connected to the upper jig 410 and is used to push the correction structure 320 toward the bent portion 123 when the lower jig 310 and the upper jig 410 are engaged. The correction structure 320 is converted from the first position to the second position, so that the correction surface 3222 of the correction structure 320 pushes the first energized section 121 to move to the docking position.

[0050] It should be noted that when the flexible circuit board 122 is in the docking position, and because the docking portion 130 is set on the flexible circuit board 122, at this time, the docking portion 130 is just arranged opposite to the plug-in portion 510 of the test module 500. When the lower fixture 310 and the upper fixture 410 are engaged, the docking portion 130 and the plug-in portion 510 can be accurately plugged and matched, ensuring that the test module 500 can test the main body 100.

[0051] Specifically, when testing the body 100, when the lower jig 310 and the upper jig 410 are engaged, the pusher 420 pushes the correction structure 320 toward the flexible printed circuit board 122. The correction surface 3222 of the correction structure 320 contacts the end face of the flexible printed circuit board 122 away from the bend 123, pushing the flexible printed circuit board 122 toward the bend 123, causing the bend 123 to deform to a certain extent. The correction structure 320 uses the correction surface 3222 to move the flexible printed circuit board 122 to the docking position and maintain the flexible printed circuit board 122 in the docking position. Furthermore, because the test module 500 is disposed on the upper jig 410, when the lower jig 310 and the upper jig 410 are engaged, the plug-in portion 510 of the test module 500 precisely plugs into and connects with the docking portion 130 of the flexible printed circuit board 122.

[0052] As can be seen from the above, even when the body 100 is being bent, there may be errors in the bending precision of the flexible circuit board 120, resulting in the plug-in portion 510 of the test module 500 being unable to accurately plug and connect with the docking portion 130 of the flexible circuit board 120 when the test module 500 is testing the body 100. In the present application, when the lower fixture 310 and the upper fixture 410 are engaged, the pusher 420 is used to push the correction structure 320 to move. During the movement of the correction structure 320, the correction surface 3222 acts on the end of the second flexible segment, so that the position of the second flexible segment is adjusted, thereby adjusting the docking portion 130 on the second flexible segment, and the plug-in portion 510 of the test module 500 can be accurately plugged and connected with the docking portion 130.

[0053] In order to enable the pushing member 420 to push the correction structure 320 toward the flexible circuit board 122, in some embodiments, referring to Figure 1 、 Figure 3 and Figure 4 The correction structure 320 is provided with a first inclined surface 3213, one edge of which is connected to the side of the correction structure 320 close to the pusher 420, and the other edge is connected to the side of the correction structure 320 away from the correction surface 3222. At the same time, the pusher 420 is provided with a second inclined surface 421, one edge of which is connected to the side of the pusher 420 close to the correction structure 320, and the other edge is connected to the side close to the test module 500. The first inclined surface 3213 and the second inclined surface 421 are able to slide relative to each other when the lower jig 310 and the upper jig 410 are engaged. Specifically, when the lower jig 310 and the upper jig 410 are engaged, the pusher 420 acts on the first inclined surface 3213 through the second inclined surface 421, thereby acting on the correction structure 320, causing the correction structure 320 to move toward the flexible printed circuit board 122, thereby moving the flexible printed circuit board 122 to the docking position and maintaining it in the docking position.

[0054] Of course, the method for achieving the movement of the correction structure 320 by the pushing member 420 is not limited to the above-described method. For example, the pushing member 420 may be a roller rotatably mounted on the upper jig 410. When the lower jig 310 and the upper jig 410 are engaged, the circumferential surface of the pushing member 420 pushes the correction structure 320 toward the flexible circuit board 122. Alternatively, the lower jig 310 may be provided with a transmission member, and the pushing member 420 acts on the transmission member, which in turn acts on the correction structure 320, thereby causing the correction structure 320 to move toward the flexible circuit board 122. This will not be described in detail.

[0055] In some embodiments, the lower fixture 310 is provided with a reference surface 3113. When the correction structure 320 abuts against the reference surface 3113, that is, when the correction surface 3222 of the correction structure 320 abuts against the reference surface 3113, the correction structure 320 cannot move further toward the flexible printed circuit board 122. At this time, the flexible printed circuit board 122 is precisely located in the docking position. The provision of the reference surface 3113 prevents the correction structure 320 from excessively moving toward the bend 123, which could result in the docking portion 130 on the second channel section not being accurately connected to the plug-in portion 510 of the test module 500.

[0056] Furthermore, the correction structure 320 includes a first sliding seat 321, a second sliding seat 322, and a second elastic member 323. The first sliding seat 321 is slidably mounted on the lower fixture 310, with its sliding direction aligned with the extension direction of the flexible printed circuit board 122. The first inclined surface 3213 is disposed on the first sliding seat 321. The first sliding seat 321 defines a guide slot 3211. One end of the guide slot 3211 extends to the edge of the first sliding seat 321 away from the second sliding seat 322. The length of the guide slot 3211 is aligned with the extension direction of the flexible printed circuit board 122. The second sliding seat 322 is slidably mounted in the guide slot 3211 and extends through the end of the guide slot 3211. The end of the second sliding seat 322 away from the first sliding seat 321 serves as the correction surface 3222. The second elastic member 323 is positioned within the guide slot 3211. One end of the second elastic member 323 abuts against the first sliding seat 321, while the other end abuts against the second sliding seat 322. The first elastic member 330 may be connected between the lower fixture 310 and the first sliding seat 321 , and the first elastic member 330 may also be connected between the lower fixture 310 and the second sliding seat 322 .

[0057] Specifically, when the lower jig 310 is engaged with the upper jig 410, the pushing member 420 acts on the first sliding seat 321, the first sliding seat 321 acts on the second elastic member 323, the second elastic member 323 acts on the first sliding seat 321, and the second sliding seat 322 is supported on the end of the flexible circuit board 122 through the correction surface 3222, thereby correcting the position of the flexible circuit board 122, and then adjusting the position of the docking portion 130.

[0058] It is understandable that if the first sliding seat 321 is fixedly connected to the second sliding seat 322, and there is an error between the first inclined surface 3213 and the second inclined surface 421, when the correction structure 320 abuts against the reference surface 3113, the pusher 420 and the correction structure 320 are in a deadlocked state, which may interfere with the normal engagement between the lower jig 310 and the upper jig 410. In the present application, the first sliding seat 321 and the second sliding seat 322 are slidably connected and abutted against each other by the second elastic member 323. In this way, even if there is an error between the first inclined surface 3213 and the second inclined surface 421, when the correction surface 3222 of the second sliding seat 322 abuts against the reference surface 3113, the first sliding seat 321 can still slide toward the second sliding seat 322, thereby absorbing the above-mentioned error and ensuring the engagement of the lower jig 310 and the upper jig 410.

[0059] Furthermore, the first sliding seat 321 is provided with a first limiting surface 3212 located inside the guide groove 3211, and the first limiting surface 3212 and the correction surface 3222 are oriented oppositely. Simultaneously, the second sliding seat 322 is provided with a second limiting surface 3221, and the second limiting surface 3221 and the correction surface 3222 are oriented in the same direction. The first limiting surface 3212 and the second limiting surface 3221 are arranged opposite each other so as to support each other. If the first elastic member 330 is connected between the lower fixture 310 and the first sliding seat 321, the first elastic member 330 acts on the first sliding seat 321 through the arrangement of the first limiting surface 3212 and the second limiting surface 3221. The first sliding seat 321 acts on the second limiting surface 3221 of the second sliding seat 322 via the first limiting surface 3212, causing the second sliding seat 322 to move away from the flexible circuit board 122, thereby facilitating the subsequent replacement of the body 100 to be tested on the lower fixture 310. At the same time, the first sliding seat 321 has a limiting effect on the second sliding seat 322 through the first limiting surface 3212 , thereby preventing the second sliding seat 322 from sliding away from the first sliding seat 321 along the guide groove 3211 .

[0060] In some embodiments, the lower fixture 310 is provided with a sliding groove 311, which includes a first groove portion 3111 and a second groove portion 3112. The first sliding seat 321 is slidably disposed in the first groove portion 3111, and the second sliding seat 322 is slidably disposed in the second groove portion 3112. The side of the second groove portion 3112 away from the first groove portion 3111 is the above-mentioned reference surface 3113. At the same time, the lower fixture assembly 300 also includes a retaining plate 340. The side wall of the first groove portion 3111 has a stepped surface 3114. The retaining plate 340 is located on the inner side of the first groove portion 3111 and is fixed to the stepped surface 3114 by screws. The inner side surface of the retaining plate 340 is in contact with the upper side wall of the first sliding seat 321 and the upper side wall of the second sliding seat 322. By providing the sliding groove 311, the retaining plate 340 and the correction structure 320 are both hidden in the sliding groove 311, preventing the correction structure 320 from interfering with the engagement between the lower fixture 310 and the upper fixture 410. The retaining plate 340 prevents the correction structure 320 from escaping the sliding groove 311.

[0061] In some embodiments, the lower jig assembly 300 further includes a plurality of limiting posts 360, for example, four limiting posts 360 are provided, and the four limiting posts 360 are connected to the lower jig 310 and are respectively located around the main body 110. In addition, the lower jig 310 is provided with suction holes for sucking the main body 110, so that the main body 110 is accurately fixed in the set position. Furthermore, the lower jig assembly 300 further includes a clamping cover 350, which is located on the upper side of the main body 110 and is rotatably connected to the lower jig 310. When the clamping cover 350 is rotated to a horizontal position, it is pressed on the upper surface of the main body 110, thereby further fixing the main body 110.

[0062] According to a second aspect of the present invention, a testing device is disclosed, referring to Figures 5 to 7, including a frame assembly 200, a conveying assembly 600, the above-mentioned correction mechanism, a test module 500 and a driving assembly 700, the frame assembly 200 includes a lower frame 210 and an upper frame 220, the upper frame 220 is arranged on the lower frame 210; the conveying assembly 600 includes a carrier 620 and a first driving member 6 10, the carrier 620 is provided with a receiving groove 621, the carrier 620 is movably arranged on the lower frame 210, and the first driving member 610 is used to drive the carrier 620 to move so that the receiving groove 621 is converted between the loading position 640 and the test position 650; the lower fixture 310 is movably placed in the receiving groove 621 and is spaced apart from the side wall of the receiving groove 621, and the upper fixture 410 is arranged on the upper frame 220; the test module 500 is arranged on the upper fixture 410, and the test module 500 has a plug-in portion 510, which is used to be plugged and connected with the docking portion 130; the driving assembly 700 is used to drive the upper fixture 410 and the lower fixture 310 to move relative to each other so that the upper fixture 410 and the lower fixture 310 are buckled together; wherein, referring to Figure 3 and Figure 4 One of the upper jig 410 and the lower jig 310 is provided with a positioning column 430, and the other is provided with a positioning hole 312. The insertion end of the positioning column 430 and / or the socket of the positioning hole 312 is provided with a correction surface 3121 with a gradually decreasing cross-section, so that the positioning column 430 can slide into the positioning hole 312 when the upper jig 410 and the lower jig 310 are engaged.

[0063] Specifically, initially, the receiving groove 621 is located at the loading position 640, so that the lower jig 310 is located at the loading position 640, and an external manipulator positions the body 100 to be tested on the lower jig 310. During testing, the first driving member 610 drives the carrier 620 to move, and the lower jig 310, with the body 100 to be tested positioned, moves to the testing position 650. The driving assembly 700 drives the lower jig 310 and the upper jig 410 to move relative to each other, and the positioning column 430 is inserted into the positioning hole 312, thereby accurately positioning the lower jig 310 and the upper jig 410, and then accurately engaging the two. When the lower jig 310 and the upper jig 410 are engaged, the plug-in portion 510 of the test module 500 is plugged into and connected with the docking portion 130 of the flexible circuit board 120, and the test module 500 is electrically connected to the body 100, thereby performing a test on the body 100, such as an RF electromagnetic frequency test or an ICT electrical function test.

[0064] The lower fixture 310 is movably placed in the receiving groove 621 and can move in a plane within the receiving groove 621 , and a correction surface 3121 with a gradually decreasing cross-section is provided at the end of the positioning column 430 and / or the socket of the positioning hole 312 . Through the above arrangement, during the movement of the carrying platform 620, even if the carrying platform 620 cannot accurately transport the lower jig 310 to the testing position 650, before the plug-in portion 510 of the test module 500 is plugged into and matched with the docking portion 130 of the flexible circuit board 120, since the correction surface 3121 makes the socket of the positioning hole 312 sufficiently large and / or makes the insertion end of the positioning post 430 sufficiently small, during the process of inserting the positioning post 430 into the positioning hole 312, the positioning post 430 gradually corrects the position of the lower jig 310 through the correction surface 3121. At this time, the lower jig 310 moves in the accommodating groove 621 until it moves to the testing position 650. Therefore, the plug-in portion 510 of the test module 500 can be accurately plugged into and connected with the docking portion 130 of the flexible circuit board, ensuring that the main body 100 can be tested normally.

[0065] In some embodiments, reference Figures 7 to 10 The driving assembly 700 includes a second driving member 710 and a lifting seat 720. The second driving member 710 is a cylinder.

[0067] Specifically, after the main body 100 is tested, the second driving member 710 drives the lifting seat 720 to move downward. The lifting seat 720 pulls the support 370 downward via the clamping portion 722. The lower fixture 310 and the support 370 move downward synchronously, thereby conveniently disengaging the plug-in portion 510 from the docking portion 130 and returning the lower fixture 310 to the accommodating groove 621. Thereafter, during the rotation of the supporting platform 620, the supporting platform 620 drives the lower fixture 310 to rotate synchronously, and the lifting seat 720 disengages from the support 370 through the end of the arc groove 371.
