Description

Technical Field

[0001] This utility model relates to the field of electronic product testing technology, specifically to an angle-adjustable swing testing device. Background Technology

[0002] Electronic circuit boards (PCBs) are frequently subjected to vibration during daily use, such as in mobile phones and automobiles. PCB oscillation testing is a core verification step to ensure product reliability throughout its entire lifecycle. This test accurately assesses the mechanical strength and signal stability of the PCB under dynamic loads by reproducing real-world scenarios such as transportation bumps, equipment vibrations, or environmental shocks. High-frequency oscillation can accelerate the exposure of problems such as soldering defects, material deformation, or poor contact, providing data support for optimized design.

[0003] Some current swing testing devices do not have the function of changing the swing amplitude (angle) at any time. Each test can only perform a single swing amplitude. It is necessary to temporarily stop the machine, adjust the equipment, and restart it before the swing amplitude can be changed. It is impossible to adjust it during the swing test, and it cannot effectively simulate the constantly changing vibration amplitude under complex conditions, thus limiting the test effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6As shown, an angle-adjustable swing testing device includes a housing 1 and a rocker arm 3. A support rod 2 is bolted to one side of the housing 1, and the rocker arm 3 is rotatably connected to the surface of the support rod 2. The top ends of the rocker arm 3 and the support rod 2 are fixed to each other by bearings to achieve a rotatable connection. A long groove 4 is formed on the surface of the rocker arm 3. A clamping and positioning assembly 5 is provided at the end of the rocker arm 3 away from the support rod 2. The clamping and positioning assembly 5 includes a fixing plate 51, a threaded sleeve 52, and a screw 53. The fixing plate 51 is bolted to one end of the rocker arm 3, and the threaded sleeve 52 is bolted to the surface of the fixing plate 51 to fix the rocker arm 3. The plate 51 is L-shaped. The screw 53 is threaded to the inner wall of the threaded sleeve 52. A handwheel 54 is bolted to the top of the screw 53 to facilitate rotation of the screw 53. The bottom of the screw 53 is fixed to a clamping plate 55 through a bearing, which makes the screw 53 rotatably connected to the clamping plate 55. The bottom of the clamping plate 55 and the surface of the fixing plate 51 are respectively fixed with a first rubber pad 56 and a second rubber pad 57. The surfaces of the first rubber pad 56 and the second rubber pad 57 are provided with anti-slip ridges to increase the friction of clamping and make it difficult for the clamped electronic circuit board to fall off.

[0027] A drive motor 6 is bolted inside the housing 1. A rotating column 7 is also rotatably connected inside the housing 1. The top of the rotating column 7 extends through to the top of the housing 1 and is bolted to a turntable 8. The connection between the rotating column 7 and the housing 1 is fixed to each other by bearings to achieve a rotatable connection. A transverse groove 9 is provided on the surface of the turntable 8. A first slider 10 is slidably connected to the inner wall of the transverse groove 9. The output shaft of the drive motor 6 is connected to the rotating column 7 through gear transmission.

[0028] A connecting post 11 is bolted to the top of the first slider 10. A second slider 12 is rotatably connected to the top of the connecting post 11. A sliding sleeve 14 is slidably connected to the surface of the rotating post 7. A push-pull rod 13 is hinged to the side of the sliding sleeve 14, and the other end of the push-pull rod 13 is hinged to the first slider 10. Both the first slider 10 and the second slider 12 are I-shaped. A long strip 17 is also welded to the surface of the rotating post 7. An inner groove 16 is also provided on the inner wall of the sliding sleeve 14, and the long strip 17 is slidably connected to the inner wall of the inner groove 16. This allows the rotating post 7 to drive the sliding sleeve 14 to rotate together during rotation, so that the sliding sleeve 14 can only move up and down along the surface of the rotating post 7. An adjustment component 15 is provided on the top of the housing 1.

[0029] During operation, the electronic circuit to be tested is first placed on the surface of the fixing plate 51 and in contact with the second rubber pad 57. Then, the handwheel 54 is turned to drive the screw 53 to rotate. The screw 53 moves downward under the action of the threaded sleeve 52. Vertical grooves 58 are provided on both sides of the surface of the fixing plate 51. Movable blocks 59 are welded on both sides of the surface of the clamping plate 55. The movable blocks 59 are slidably connected to the inner wall of the vertical groove 58. During the descent of the screw 53, the clamping plate 55 is driven to descend together. The clamping plate 55 drives the movable blocks 59 to slide downward along the inner wall of the vertical groove 58. The first rubber pad 56 at the bottom of the clamping plate 55 is in contact with the top edge of the electronic circuit board, thereby clamping and fixing the electronic circuit board.

[0030] When the drive motor 6 is turned on, its output shaft drives the rotating column 7 to rotate through the gear. The rotating column 7 drives the turntable 8 to rotate, thereby causing the transverse groove 9 on the surface of the turntable 8 to make a circular motion. This, in turn, causes the first slider 10, the connecting column 11, and the second slider 12 to make a circular motion. The second slider 12 then pushes the long groove 4, causing the rocker arm 3 to swing back and forth, thus performing a swing test on the clamped and fixed electronic circuit board.

[0031] The adjusting assembly 15 includes an electric cylinder 151, a connecting frame 152, and rollers 153. Two sets of electric cylinders 151 are bolted to both sides of the top of the housing 1. The connecting frame 152 is bolted to the output shaft of the electric cylinder 151. The rollers 153 are rotatably connected to the surface of the connecting frame 152. A connecting plate 154 is welded to the surface of the sliding sleeve 14, and the rollers 153 are respectively disposed on the upper and lower sides of the connecting plate 154 and in contact with it. During rotation, the rotating column 7 can drive the sliding sleeve 14 and the connecting plate 154 to rotate together, and the rollers 153 can contact the rotating connecting plate 154. Activating the electric cylinder 151 extends its output, thereby raising the connecting frame 152 and the rollers 153, and pushing the rotating connecting plate 154 and the sliding sleeve 14 upwards. The sliding sleeve 14 is connected to the sliding rod 1... 3. Push the first slider 10 to move, so that the first slider 10 and the connecting column 11 move away from the center of the turntable 8. In the reciprocating rocking mechanism (such as the crank rocker mechanism), when other conditions remain unchanged, the longer the crank, that is, the longer the distance between the first slider 10 and the center of the turntable 8, the greater the swing amplitude of the rocker arm 3. Activate the electric cylinder 151 to retract its output shaft, which can drive the connecting frame 152, roller 153, connecting plate 154 and sliding sleeve 14 to descend, and pull the first slider 10 closer to the center of the turntable 8 through the push-pull rod 13, so that the crank becomes shorter, that is, the distance between the first slider 10 and the center of the turntable 8 becomes shorter, and the swing amplitude of the rocker arm 3 becomes smaller. Thus, during the rocking test, the swing amplitude, that is, the swing angle, can be adjusted. It is convenient to use and does not require stopping the machine for adjustment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
