Detailed Description of the Invention

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] It can be understood that the terms "first", "second", etc. used in this application can be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0020] As Figures 1-3 shown, in one embodiment, a COMPASS test device for a flexible printed circuit assembly is proposed. The COMPASS test device for the flexible printed circuit assembly includes: Frame assembly 100; Bracket assembly 200, arranged within the frame assembly 100; the bracket assembly 200 includes a bracket base plate 210, bracket side plates 220 and a bracket top plate 230. One end of the bracket side plate 220 is arranged in the positioning groove of the bracket base plate 210, and the other end is arranged in the positioning groove of the bracket top plate 230; both the bracket base plate 210 and the bracket top plate 230 are provided with coils 240; Inclined platform 300, arranged on the bracket base plate 210; SOCKET component 400, positioned and arranged on the inclined platform 300, and the SOCKET component 400 is used for placing products; Test component 500, arranged on the frame assembly 100, for connecting the coil 240 to perform product function testing.

[0021] In this embodiment, the frame assembly 100 is the housing of the COMPASS test device, which plays a role in supporting and protecting, and provides a test space for product function detection. AsFigure 2 As shown, there are three positioning grooves provided on the bracket bottom plate 210, and correspondingly three are provided on the bracket side plates 220, which are respectively inserted into the three positioning grooves; and there are also positioning grooves provided on the bracket top plate 230 for inserting the bracket side plates 220. The coil 240 is divided into an upper coil and a lower coil. The upper coil is positioned on the bracket top plate 230 through a coil limiting plate. Similarly, the lower coil is positioned at the bottom of the bracket bottom plate 210 through a coil limiting plate. In addition, the inclined platform 300 is positioned on the bracket bottom plate 210 and is fixedly installed on the bracket bottom plate 210 through two left and right fixing plates.

[0022] In this embodiment, the product is a COMPASS component, which is an electronic component for detecting the magnetic field strength and magnetic field direction in consumer electronic products. After the COMPASS component is mounted on the FPC, the component needs to be subjected to ICT testing and FCT testing. The test contents include conventional ICT items such as circuit continuity, line resistance value, current and voltage values, etc., and the component also needs to be subjected to functional testing. During the test, the center point of the component must coincide with the midpoint of the axis of the Helmholtz coil, and the XYZ three axes of the component need to form a specified angle with the axis. The Helmholtz coil will generate a uniform monopole magnetic field at the center during the test, and the magnetic field strength is the value specified in the test document. The magnetic field direction will also change during the test. The component will obtain a series of parameters according to the external magnetic field environment, and the component is analyzed for qualification based on the parameters. This test requires a relatively high position and angle accuracy of the component relative to the coil. Otherwise, the GRR and CPK values cannot meet the standards, and the test results of the same product by different devices cannot be correlated.

[0023] Therefore, in this embodiment, a bracket assembly 200 is designed outside the inclined platform 300. By ensuring the positioning between the inclined platform 300 and the bracket bottom plate 210, the positioning between the bracket bottom plate 210 and the bracket side plates 220, the positioning between the bracket side plates 220 and the bracket top plate 230, the positioning between the coil 240 and the bracket top plate 230, and the positioning between the coil 240 and the bracket bottom plate 210, the magnetic field direction is precisely aligned with the product component at an angle, thereby improving the test accuracy. The COMPASS test equipment designed according to the component test requirements in this embodiment has been verified by production. The COMPASS test has a high yield rate and is applicable to different flexible boards containing COMPASS.

[0024] In this embodiment, as Figure 4As shown, the test component 500 is the structure of a test box, which is integrally arranged on the frame component 100. The test component 500 includes a test bottom plate 510, a test frame 520, and a test cover 530. The test bottom plate 510 is installed on the frame component 100, the test frame 520 is installed on the test bottom plate 510, and the test cover 530 covers the test frame 520 to form a box structure. Various electrical components are installed inside the test frame 520, including but not limited to a cooling fan, a power supply, interfaces, a transfer board, and a test board. Buttons and indicator lights are arranged on the outer side of the test frame 520.

[0025] In an optimized solution, as Figure 5 shown, the frame component 100 is specifically defined. The frame component 100 includes: A frame bottom plate 110 that restricts the support bottom plate 210 on the frame bottom plate 110; Frame side plates 120 fixedly installed on the frame bottom plate 110; A frame door plate 130 rotatably installed on one side of the frame side plates 120 and buckled to the other side of the frame side plates 120; An induction sheet 140 arranged on the frame door plate 130; A proximity switch 150 arranged inside the frame component 100.

[0026] In this optimized solution, the frame component 100 is a device frame. There are three frame side plates 120 and one frame door plate 130. The rotary handle on the frame door plate 130 can be associated with the lock on the side plate to realize the opening, closing, and locking of the frame door plate 130. The induction sheet 140 on the frame door plate 130 and the proximity switch 150 can detect whether the door is closed, and the test can only be carried out when it is closed. Among them, the support limit plates 160 and the baffle plates 170 on the left and right sides of the support bottom plate 210 can limit the support component 200 to improve the stability of the support component 200.

[0027] In an optimized solution, as Figure 3 shown, the inclined table 300 is specifically defined. The inclined table 300 is inclined so that the center point of the product is on the same axis as the center point of the coil 240, and the XYZ three axes of the product components form a specified angle with the axis; the inclined table 300 includes: A SOCKET limit plate 310 inclined for placing the SOCKET component 400; A positioning pin 320 arranged on the SOCKET limit plate 310 for positioning the SOCKET component 400; A guide block 330 arranged on the SOCKET limit plate 310 to fix the SOCKET component 400 on the SOCKET limit plate 310 through a ball head plunger; The transfer module 340 is arranged on the SOCKET limiting plate 310 and is used to transfer the test signal on the SOCKET component 400.

[0028] In this optimization solution, the SOCKET component 400 is movable and is detachably connected to the inclined table 300. Placing the SOCKET component 400 on the inclined table 300 is the feeding process. Since the inclined table 300 is inclined, the stability of the installation of the SOCKET component 400 must be considered. Therefore, the positioning pin 320 and the guiding block 330 are designed in this optimization solution; the SOCKET limiting plate 310 is the tabletop of the inclined table 300, and the positioning pin 320, the guiding block 330 and the transfer module 340 are arranged on it. The positioning pin 320 of the inclined table 300 is in guiding connection with the bushing on the SOCKET component 400, and the periphery of the SOCKET component 400 is limited by the guiding block 330, and the ball head plunger can ensure the stability of the limiting fixation.

[0029] Among them, as Figure 3 shown, the transfer module 340 includes: The bracket transfer plate 341 is arranged on the SOCKET limiting plate 310 and is used to connect the test signal to the test component 500; The lower transfer block 342 is arranged on the bracket transfer plate 341; The upper transfer block 343 is arranged on the lower transfer block 342; The transfer pin 344 is arranged between the lower transfer block 342 and the upper transfer block 343 and is used to transfer the test signal of the SOCKET component 400 to the bracket transfer plate 341.

[0030] In this optimization solution, the transfer module 340 is used to transfer the signal of the SOCKET component 400, and the transfer pin 344 is docked with the pin mold transfer plate 425 of the SOCKET component 400. The lower transfer block 342 and the upper transfer block 343 are used to fix the transfer pin 344 so that the transfer pin 344 can accurately pierce the pin mold transfer plate 425.

[0031] In an optimization solution, as Figures 6-8 shown, the SOCKET component 400 is specifically defined. The SOCKET component 400 includes: The SOCKET bottom plate 410 is positioned on the inclined table 300; The pin mold module 420 is arranged on the SOCKET bottom plate 410 and is used to place the product; The first limiting module 430 is arranged on one side of the pin mold module 420 and is used to limit the product on the pin mold module 420; The second limiting module 440 is used to limit the needle die module 420 so that the probe 424 pierces the product connector at the specified position.

[0032] In this optimized solution, a bushing is provided on the SOCKET base plate 410, which can be connected to the positioning pin 320 on the inclined table 300 in a guiding manner to achieve precise docking; several guiding blocks 330 are also provided on the inclined table 300, and the SOCKET base plate 410 can be fixed between the guiding blocks 330 through the ball plungers in the guiding blocks 330. A working position for placing the product is provided on the needle die module 420, B2B connector contacts are provided on the product, and a B2B positioning block is also provided on the needle die module 420. The B2B positioning block can position the flexible board to ensure precise needle piercing test. Both the first limiting module 430 and the second limiting module 440 are pressing and limiting structures, and fixation or needle piercing is achieved by applying a downward mechanical force. In this embodiment, two limiting modules are provided. The first limiting module 430 first fixes the product and then presses down the needle die module 420 to achieve needle piercing. This design is more reasonable and meets the requirements of the production operation process.

[0033] In the above optimized solution, as Figure 7 shown, the needle die module 420 includes: The first needle die 421 is provided with a working position for placing the product; The second needle die 422 is arranged at the bottom of the first needle die 421 and is floatingly connected to the first needle die 421; The third needle die 423 is arranged at the bottom of the second needle die 422; The probe 424 is fixedly arranged between the second needle die 422 and the third needle die 423, and the tip of the probe 424 extends into the first needle die 421 for testing the test points on the product; The needle die adapter plate 425 is arranged at the bottom of the third needle die 423 and is fixedly connected to the SOCKET base plate 410 for transferring the test signal to the transfer module 340 of the inclined table 300.

[0034] In this optimized solution, a first needle die 421 limiting plate is also provided on the needle die module 420. The first needle die limiting plate is arranged above the first needle die 421 to limit the upward movement of the first needle die 421. The first needle die 421 and the second needle die 422 are connected by an elastic member and a guiding pin to ensure that the first needle die 421 is floatingly connected between the first needle die limiting plate and the second needle die 422. The second needle die 422 is fixed to the third needle die 423, and the probe 424 is arranged between them. When the second limiting module 440 presses down, the first needle die 421 moves downward and fits with the second needle die 422. At this time, one end of the probe 424 pierces the test point of the product, and the other end pierces the needle die adapter plate 425, thereby conducting the circuit and realizing the function test.

[0035] In the above optimization solution, as Figure 7 shown, the first limiting module 430 includes: The first rotating seat 431 is fixedly arranged on the SOCKET bottom plate 410, close to the needle die module 420; The first rotating pressing block 432 is connected to the first rotating seat 431 through a first rotating reset structure, and is used to limit the product on the needle die module 420.

[0036] In this optimization solution, the first rotating seat 431 is divided into a right rotating seat and a left rotating seat, and the first rotating pressing block 432 is arranged between the two. The first rotating reset structure selects a torsion spring and a rotating pin. The rotating pin is sequentially inserted into the right rotating seat, the first rotating pressing block 432 and the left rotating seat, and the torsion spring is arranged on the rotating pin, so as to realize rotating reset. It can be understood that the second rotating reset structure and the third rotating reset structure in the following optimization solutions can both be this matching structure of the torsion spring and the rotating pin. The first rotating pressing block 432 is a steel sheet pressing block, with a pre-pressure, which can press the product to achieve fixation.

[0037] In the above optimization solution, as Figure 7 and 8 shown, the second limiting module 440 includes: The second rotating seat 441 is fixedly arranged on the SOCKET bottom plate 410, The second rotating pressing block 442 is connected to the second rotating seat 441 through a second rotating reset structure; The needle die pressing block 443 is arranged on the second rotating pressing block 442, and is used to press the first needle die 421 so that the first needle die 421 is attached to the second needle die 422; The COMPASS pressing block 444 is arranged on the second rotating pressing block 442, and is used to secondarily limit the product.

[0038] In this optimization solution, the second rotating pressing block 442 is a flip cover, which is the cover plate of the entire SOCKET assembly 400 and covers the SOCKET bottom plate 410 from above. There are two pressing blocks on the second rotating pressing block 442. One is the needle die pressing block 443, which is used to realize the needle piercing test, and the other is the COMPASS pressing block 444, which is used to further fix the product and improve the product fixing effect.

[0039] In the above optimization solution, as Figure 7 and 8 shown, the second limiting module 440 further includes: The pressing block cover plate 445 is fixedly arranged on the second rotating pressing block 442; The reset spring 446 is arranged inside the second rotary pressing block 442, with one end connected to the pressing block cover plate 445 and the other end connected to the needle die pressing block 443 and the COMPASS pressing block 444.

[0040] In this optimized solution, the two pressing blocks on the second rotary pressing block 442 are elastically connected. A groove is arranged inside the second rotary pressing block 442. The needle die pressing block 443 and the COMPASS pressing block 444 are embedded inside the groove, and the extrusion force is transmitted through the reset spring 446 to avoid damaging the surface of the product due to the impact force during downward pressing.

[0041] In the above optimized solution, as Figure 7 and 8 shown, the second limiting module 440 further includes a buckle module, and the buckle module includes: A fastener 447, which is rotatably connected to the second rotary pressing block 442 through a third rotary reset structure; A limiting member 448, which is fixedly arranged on the SOCKET bottom plate 410 and is buckled with the fastener 447; A limiting platform 449, which is fixedly arranged on the SOCKET bottom plate 410 and is used to support and limit the second rotary pressing block 442.

[0042] In this optimized solution, the fastener 447 is arranged at one end of the second rotary pressing block 442 away from the second rotary seat 441, and the limiting member 448 is arranged at one end of the SOCKET bottom plate 410 away from the second rotary seat 441. The third rotary reset structure can be a rotary pin or a combination of a rotary pin and a torsion spring. The fastener 447 is connected through the third rotary reset structure, and single - hand pressing for disassembly and installation can be realized, which is more convenient. The limiting platform 449 is used to limit the extreme position of the second rotary pressing block 442 to avoid over - pressing and damaging the product.

[0043] In the working process of the invention embodiment: Before testing, the second rotary pressing block 442 is opened through the fastener 447, and the first rotary pressing block 432 is rotated by hand - pressing. The product is placed into the product positioning groove of the first needle die 421, and the first rotary pressing block 432 is released. It presses the product under the action of the torsion spring, and at this time the product is completely limited; then the second rotary pressing block 442 is rotated to make it closed, the fastener 447 on the flip cover is buckled with the limiting member 448, the needle die pressing block 443 on the flip cover will press the first needle die 421 onto the surface of the second needle die 422, the probe 424 in the second needle die 422 pierces the point of the product connector, and the elastic COMPASS pressing block 444 presses above the product element, and the element is completely limited.

[0044] Then put the SOCKET component 400 into the ramp 300 in the bracket component 200 and place it on the SOCKET limit plate 310. The positioning pin 320 of the SOCKET limit plate 310 is docked with the bushing on the SOCKET for positioning. The ball plunger in the guide block 330 limits and fixes the SOCKET component 400. One end of the adapter module 340 of the SOCKET limit plate 310 is inserted into the docking point of the needle mold adapter plate 425 on the SOCKET component 400, and the other end is inserted into the bracket adapter plate 341. The bracket adapter plate 341 is connected to the test board in the test component 500 through a flat cable. Then close the rack door panel 130 and rotate the handle to lock it. Press the start button of the test component 500 to start the test. After the test is completed, remove the SOCKET component 400 from the bracket component 200 to start the cycle.
