Description

Technical Field

[0001] This utility model relates to the field of circuit board deformation testing technology, and in particular to a circuit board deformation testing device. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are core components that provide mechanical assembly support and electrical connections for various electronic systems. They also carry out signal transmission, signal reception and power supply for electronic devices. After the circuit boards are soldered into shape, samples need to be tested for stress deformation resistance of the solder joints using circuit board deformation testing equipment.

[0003] In the existing technology, circuit board deformation testing equipment is inconvenient when testing circuit boards that require double-sided testing. When flipping the circuit board, it is necessary to remove the circuit board from the clamping mechanism, flip it over, and then put it back on the clamping mechanism. In addition, most current clamping mechanisms use threaded rod structures for clamping, which makes it inconvenient to place and remove the circuit board. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit board deformation testing device to solve the problems mentioned in the background art, which are inconvenient when testing circuit boards that need to be tested on both sides. Furthermore, the current clamping mechanisms mostly use threaded rod structures for clamping, which makes it inconvenient to place and remove the circuit boards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a test frame mechanism and a circuit board body. The test frame mechanism includes a test chamber, a stabilizing block, a stabilizing groove, an extension plate, a fixing block, and a support plate. A pressing component is provided on the top of the test frame mechanism. A placement mechanism is provided inside the test frame mechanism. The placement mechanism includes a placement frame, a sliding groove, a moving groove, a movable groove, and a movable slot. A flipping mechanism is provided inside both sides of the placement mechanism. The flipping mechanism includes a connecting spring, a moving block, a moving rod, a rotating block, a clamping frame, a spring groove, a return spring, a blocking block, a connecting groove, a hollow groove, and a connecting plate.

[0006] In a preferred embodiment, the inner wall of the test chamber is fixedly connected to one side of the stabilizing block, and a stabilizing groove is provided inside the stabilizing block. The inner wall of the stabilizing groove is movably connected to the outer wall of the circuit board body.

[0007] In a preferred embodiment, one side of the test chamber is fixedly connected to one side of the extension plate, and one side of the extension plate is fixedly connected to one side of the fixing block. The bottom side of the test chamber is fixedly connected to one side of the support plate, and an extrusion member is provided on the top of the test chamber.

[0008] In a preferred embodiment, the inner wall of the test chamber is movably connected to the outer wall of the placement rack, and sliding grooves are provided on both outer walls of the placement rack. The inner wall of the sliding groove is movably connected to the outer wall of the fixed block, and movable grooves are provided on both sides of the placement rack.

[0009] In a preferred embodiment, the inner wall of the movable groove is fixedly connected to one end of the connecting spring, and the other end of the connecting spring is fixedly connected to one side of the movable block. One side of the movable block is fixedly connected to the outer wall of the movable rod, and the outer wall of the movable rod is movably connected to the interior of the movable groove. The outer wall of the movable block is movably connected to the inner wall of the movable groove.

[0010] In a preferred embodiment, one end of the movable rod is rotatably connected to one end of the inner wall of the rotating block via a bearing, and the other end of the rotating block is fixedly connected to one side of the clamping frame. Spring grooves are provided inside both sides of the clamping frame.

[0011] In a preferred embodiment, the inner wall of the spring groove is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to one side of the blocking block. A connecting groove is provided on one side of the spring groove, and the outer wall of the blocking block is movably connected to the inside of the spring groove.

[0012] In a preferred embodiment, a hollow groove is provided on one side of the connecting groove, one side of the blocking block is fixedly connected to both sides of the connecting plate, and the outer wall of the connecting plate is movably connected to the inner wall of the connecting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the placement frame is pulled out, the clamping frame is rotated to flip the circuit board body that has been initially stabilized by the blocking block. Then the placement frame is pushed into the test chamber, thereby performing bidirectional deformation testing on the circuit board body, which facilitates the testing of double-sided solder joints on the circuit board body.

[0015] 2. In this utility model, pushing the connecting plate at the top causes the blocking block to enter the spring groove, while simultaneously compressing the reset spring. The circuit board body is placed between the clamping frames, blocked by the blocking block at the bottom. Simultaneously, releasing the connecting plate allows the reset spring to move the blocking block to block the top of the circuit board body, thus initially stabilizing it. The placement frame is then pushed into the test chamber by the stabilizing block. Simultaneously, the inner wall of the test chamber compresses one end of the moving rod, causing it to move and thus the clamping frame to compress both sides of the circuit board body. Simultaneously, the moving block compresses the connecting spring. After the circuit board body is fully inside the test chamber, one side of the circuit board body enters the stabilizing groove. When the placement frame is pulled out, the reset spring loosens the clamping frame, facilitating the placement and removal of the circuit board body and simplifying the clamping operation.

[0026] In one embodiment, the inner wall of the test chamber 101 is fixedly connected to one side of the stabilizing block 102, and the stabilizing block 102 has a stabilizing groove 103 inside, and the inner wall of the stabilizing groove 103 is movably connected to the outer wall of the circuit board body 5.

[0027] Specifically: After the circuit board body 5 is fully inserted into the test chamber 101, one side of the circuit board body 5 enters the interior of the stabilizing groove 103.

[0028] In one embodiment, one side of the test chamber 101 is fixedly connected to one side of the extension plate 104, and one side of the extension plate 104 is fixedly connected to one side of the fixing block 105. The bottom side of the test chamber 101 is fixedly connected to one side of the support plate 106, and the top of the test chamber 101 is provided with an extrusion member 2.

[0029] Specifically, the stability of the placement rack 301 is ensured by the setting of the extension plate 104, the fixing block 105 and the support plate 106.

[0030] In one embodiment, the inner wall of the test chamber 101 is movably connected to the outer wall of the placement rack 301, and both outer walls of the placement rack 301 are provided with sliding grooves 302. The inner wall of the sliding grooves 302 is movably connected to the outer wall of the fixing block 105. Both sides of the placement rack 301 are provided with moving grooves 303, and both sides of the moving grooves 303 are provided with moving grooves 304.

[0031] Specifically, the stability of the moving block 402 and the moving rod 403 is ensured by the setting of the moving groove 303 and the movable groove 304.

[0032] In one embodiment, the inner wall of the movable groove 304 is fixedly connected to one end of the connecting spring 401, and the other end of the connecting spring 401 is fixedly connected to one side of the movable block 402. One side of the movable block 402 is fixedly connected to the outer wall of the movable rod 403, and the outer wall of the movable rod 403 is movably connected to the interior of the movable groove 303. The outer wall of the movable block 402 is movably connected to the inner wall of the movable groove 304.

[0033] Specifically: the reset of the connecting spring 401 loosens the clamp 405, making it easier to place and remove the circuit board body 5.

[0034] In one embodiment, the outer wall of one end of the moving rod 403 is rotatably connected to the inner wall of one end of the rotating block 404 via a bearing, and the other end of the rotating block 404 is fixedly connected to one side of the clamping frame 405. Spring grooves 406 are provided inside both sides of the clamping frame 405.

[0035] Specifically: while being pushed in, the inner wall of the test chamber 101 presses against one end of the moving rod 403, thereby causing the moving rod 403 to move, which in turn causes the clamping frame 405 to press against both sides of the circuit board body 5.

[0036] In one embodiment, the inner wall of the spring groove 406 is fixedly connected to one end of the return spring 407, and the other end of the return spring 407 is fixedly connected to one side of the blocking block 408. A connecting groove 409 is provided on one side of the spring groove 406, and the outer wall of the blocking block 408 is movably connected to the inside of the spring groove 406.

[0037] Specifically: when the connecting plate 411 is released, the reset spring 407 causes the blocking block 408 to block the top of the circuit board body 5, thereby initially stabilizing the circuit board body 5.

[0038] In one embodiment, a hollow groove 410 is provided on one side of the connecting groove 409, one side of the blocking block 408 is fixedly connected to both sides of the connecting plate 411, and the outer wall of the connecting plate 411 is movably connected to the inner wall of the connecting groove 409.

[0040] Working principle: Pushing the connecting plate 411 at the top causes the blocking block 408 to enter the spring groove 406, simultaneously compressing the reset spring 407. This places the circuit board body 5 between the clamping frames 405, where it is blocked by the blocking block 408 at the bottom. Simultaneously, releasing the connecting plate 411 causes the reset spring 407 to move the blocking block 408 to block the top of the circuit board body 5, thus initially stabilizing it. The placement frame 301 is then pushed into the test chamber 101 by the stabilizing effect of the fixing block 105. Simultaneously, the inner wall of the test chamber 101 compresses one end of the moving rod 403, thereby driving the moving rod... The moving rod 403 moves, thereby causing the clamping frame 405 to press against both sides of the circuit board body 5. At the same time, the moving block 402 presses against the connecting spring 401. After the circuit board body 5 is fully inserted into the test chamber 101, one side of the circuit board body 5 enters the interior of the stabilizing groove 103. When the placement frame 301 is pulled out, the clamping frame 405 is loosened by the reset of the connecting spring 401. When the placement frame 301 is pulled out, the clamping frame 405 is rotated to flip the circuit board body 5, which was initially stabilized by the blocking block 408. Then the placement frame 301 is pushed into the interior of the test chamber 101, thereby performing a bidirectional deformation test on the circuit board body 5.
