Description

Technical Field

[0001] The utility model relates to the field of circuit board detection, in particular to a flexible circuit board detection auxiliary fixture. Background Art

[0002] Flexible printed circuits, also known as soft boards, are printed circuit boards made from a flexible insulating substrate. They offer many advantages over rigid printed circuit boards. They can be freely bent, rolled, and folded, arranged to fit spatial layout requirements, and moved and extended in three dimensions, enabling the integration of component assembly and wire connections. Flexible circuits can significantly reduce the size of electronic products, meeting the trend toward higher density, miniaturization, and higher reliability. After production, flexible circuit boards require testing, or quality inspection. This inspection process requires the use of auxiliary jigs to control the position of the flexible circuit boards.

[0003] A Chinese patent discloses a flexible circuit board detection auxiliary jig with patent number CN216209683U. In the patent, the flexible circuit board detection auxiliary jig includes a base plate, a mounting plate is symmetrically fixed on the upper end of the base plate, an adjustment motor is installed on the left mounting plate, the output shaft of the adjustment motor is connected to a rectangular frame, a rotating rod is fixed on the right end of the rectangular frame, a strip block is symmetrically fixed on the inner side of the rectangular frame, a number of limiting teeth are fixed on the strip block, a movable block is symmetrically sleeved on the outer side of the rectangular frame, a mounting cavity is opened on the inner side of the movable block, a circular cavity is symmetrically opened on the inner wall of the mounting cavity, a locking mechanism is symmetrically opened inside the mounting cavity, a rectangular block is fixed on the movable block, a groove is symmetrically opened on the rectangular block, and a clamping mechanism is arranged in the groove; a flexible circuit board detection auxiliary jig can adjust the position of the movable blocks on both sides according to the specifications of the flexible circuit board, can flip the flexible circuit board over to continue the detection work, and improves the convenience of the detection work.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, when a jig is used to assist in the inspection of a flexible circuit board, since the jig needs to clamp and fix the flexible circuit board, it may clamp the circuit board too hard during use, causing damage to the circuits on the surface of the flexible circuit board and electric shock, affecting the subsequent normal use of the flexible circuit board.

[0006] (2) In the prior art, after the fixture limits and fixes the flexible circuit board, the contact position between the fixture and the flexible circuit board is the same, which makes the operation process more complicated when testing different positions of the flexible circuit board, affecting the testing efficiency.

[0007] (3) In the prior art, after the flexible circuit board fixed by the fixture is tested, the flexible circuit board needs to be replaced to facilitate the subsequent testing of other flexible circuit boards. However, the replacement process is relatively cumbersome, which affects the testing efficiency. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, a flexible circuit board detection auxiliary fixture includes a base plate 1, a support leg 101 with an anti-slip pad 102 is provided on the bottom surface of the base plate 1 to prevent sliding during the detection process, a fixed frame 2 located on the surface of the base plate 1, and a rotating member 201 installed on one side rotates on the surface of a fixed shaft 203 fixed on the inner side of the fixing member 202, making the fixing frame 2 more convenient to open and close, and a snap assembly 3 provided on one side is provided with a card plate 301, which is clamped to the inner side of the card plate 301 by the card member 302, and is locked in the button Driven by 304, the snap assembly 3 can control the opening and closing of the fixed frame 2. The adjustment plate 4 located on the inner side of the fixed frame 2 slides and adjusts its position through the limit rods 401 and the slide rods 402 on the inner sides of both ends. The buffer clamping assembly 5 fixed on the surface of the adjustment plate 4 is provided with a screw 501. The movable plate 502 connected by rotation at the bottom end of the screw 501 is connected to the pressure plate 504 under the setting of the support rod 503, and a buffer spring 505 is provided on the surface of the support rod 503 to drive the pressure plate 504 for buffering clamping.

[0032] Bumps are provided on both sides of the placement plate 103 provided on the surface of the bottom plate 1 .

[0033] Through the above technical solution, the flexible circuit board can be placed on the surface of the placement plate 103, and under the limitation of the protrusions, the fixing frame 2 can be prevented from directly squeezing the flexible circuit board.

[0034] The clamping member 302 rotates on the surface of the limiting shaft 303 fixed on the inner side of the base plate 1, and a spring 305 fixed on the inner side of the base plate 1 is provided on the bottom surface of the clamping member 302.

[0035] Through the above technical solution, the clamping member 302 is connected to the spring 1 305 so that when the clamping member 302 is driven by the button 304 , it can squeeze the spring 1 305 , thereby separating the clamping member 302 from the clamping plate 301 .

[0036] A push block 307 is installed on the upper end of the spring 2 306 arranged on one side of the spring 1 305 so that the push block 307 can fit on the bottom surface of the clamping plate 301 .

[0037] Through the above technical solution, under the elastic force of the second spring 306, after the clamping member 302 is separated from the clamping plate 301, the pushing force of the second spring 306 can enable the pushing block 307 to push the clamping plate 301 out, making it easier to separate.

[0038] An insert block 404 is provided inside the limiting groove 403 provided on the surface of the slide bar 402 , and a baffle 405 on the surface of the insert block 404 is capable of fixing the spring three 406 .

[0039] Through the above technical solution, under the elastic force of the spring three 406, the insert block 404 can be inserted into the inner side of the limiting groove 403, which is convenient for limiting the position of the adjustment plate 4.

[0040] The screw 501 threadedly connected to the surface of the adjustment plate 4 can push the movable plate 502 to adjust its position. With the assistance of the buffer spring 505 located between the movable plate 502 and the pressure plate 504, the pressure plate 504 can be fitted on top of the flexible circuit board.

[0041] Through the above technical solution, the position of the movable plate 502 is adjusted by the screw 501, which facilitates the adjustment of the position of the pressure plate 504, and elastic clamping is performed by the buffer spring 505.

[0042] When in use, when the user uses the flexible circuit board detection auxiliary jig, he presses the button 304 to make the clamping member 302 rotate around the limit axis 303 under the elastic force of the spring 1 305, thereby breaking away from the clamping connection with the clamping plate 301, so that the fixing frame 2 can rotate around the fixed axis 203 through the rotating member 201 fixed by the fixing member 202, open the fixing frame 2, and then place the flexible circuit board to be tested on the surface of the placement plate 103, and then close the fixing frame 2 through the buckle assembly 3. Under the elastic force of the spring 3 406, The insert block 404 is disengaged from the limit slot 403, making it convenient to move the adjustment plate 4 under the limit of the limit rod 401 and the slide rod 402, so that the position of the adjustment plate 4 can be adapted to different flexible circuit boards. Then, the movable plate 502 is pushed to move by rotating the screw 501, so that the pressure plate 504 can be attached to the surface of the flexible circuit board with the assistance of the buffer spring 505 to clamp it. When the flexible circuit board for inspection needs to be replaced, it is only necessary to open the fixing frame 2 through the button 304 to conveniently replace it.
