Technical Field

The present invention relates to a dynamic test module with a mechanism for limiting over-rotation, and more particularly, to a dynamic test module with a mechanism for limiting over-rotation suitable for a test machine.

Background

Motion sensors, which are elements capable of converting motion states (such as tilt angles) into corresponding electrical signals, are increasingly commonly used in modern electronic or electromechanical devices, such as game controllers, mobile phones, digital music players (MP3), cameras, Personal Digital Assistants (PDAs), and various motion-related applications (such as flipping, accelerating, rotating, etc.) to promote reality, convenience, or functional diversity. The motion sensor of the present invention is generally fabricated as an integrated circuit by a semiconductor process technology in combination with an electromechanical technology. As with conventional integrated circuits, final test (final test) is required on the packaged motion sensor to ensure its functional correctness. In addition to the functional and electrical parameters, the accuracy of the motion state of the device is also tested during the test.

Please refer to fig. 8, which is a perspective view of a conventional flip test module. As shown in the drawings, in the prior art, such as the "flipping test module and the test system thereof" disclosed in taiwan patent publication No. TW 201031935a1, the flipping test module 9 mainly includes a first flipping mechanism 921 and a second flipping mechanism 922, and the first flipping mechanism 921 is controlled by a first driving device 931 (e.g. a stepping motor) to flip around a first axis (e.g. the Y axis in the drawings); the second flipping mechanism 922 (disposed inside the first flipping mechanism 921) is controlled by a second driving device 932 (e.g. a stepping motor) to flip around a second axis (e.g. X axis of the drawing). The dut accommodated in the socket 90 is fixed on the second flipping mechanism 921 through the component interface board. The motion sensor to be tested can be turned over at a single or continuous different angle according to the requirement, and output signals in various turning states are transmitted to a testing machine through the transmission line 91.

However, when the inversion testing module 9 of the prior art is tested, the number of turns or the inversion angle of the inversion testing module is limited by the factor of pulling the transmission line 91, and if the inversion testing module is not provided with the over-rotation limiting mechanism, the inversion mechanism is easily over-set by human error or malfunction of the machine, and the maximum rotation angle of the inversion mechanism is over-set, so that the first driving device 931 and the second driving device 932 are over-rotated to pull the transmission line 91, and the transmission line is damaged or abnormal.

The present invention is conceived based on the spirit of the active invention, and several research experiments have completed the present invention by devising a dynamic test module with over-rotation limiting mechanism capable of solving the above problems.

In order to achieve the above object, the dynamic testing module with over-rotation limiting mechanism of the present invention comprises a dynamic turning mechanism and an over-rotation limiting mechanism. The dynamic turnover mechanism is connected with a driving module and is provided with an accommodating space capable of accommodating at least one tested element for carrying out dynamic turnover test; the over-rotation limiting mechanism comprises a rotating shaft connected with the dynamic turnover mechanism and a base erected above the rotating shaft, the rotating shaft is provided with a plurality of guide grooves, a slide rail is arranged on the base and can be used for a front stop block, a rear stop block and a sliding piece which are positioned on the slide rail to slide, and the sliding piece is connected with a guide pillar which is accommodated in the guide grooves.

When the rotating shaft rotates, the sliding piece is driven by the guide of the guide post and slides towards the front stop block or the rear stop block according to different rotating directions of the rotating shaft. Through the design, the invention can convert the rotation kinetic energy of the rotating shaft into the linear displacement of the sliding piece, and further limit the maximum limit rotation angle of the dynamic testing module through the separation of the front stop block and the rear stop block, thereby effectively preventing the dynamic testing module from exceeding the set maximum rotation angle.

The front stop block and the rear stop block can be adjustable stop blocks and are positioned at specific positions of the slide rail according to different requirements. Therefore, the limit rotation angle of the dynamic test module can be conveniently adjusted by a user, and the flat cable is prevented from being pulled by the driving module due to the over rotation.

The front block and the rear block can be respectively provided with at least one locking piece for respectively and correspondingly locking in a plurality of positioning holes formed in the slide rail. Therefore, the front stop block and the rear stop block can be conveniently locked at specific positions of the slide rail by a user, and the two stop blocks can be adjusted and fixed conveniently.

The front stop block and the rear stop block can be respectively provided with an oil buffer for absorbing the impact force generated when the sliding piece collides, and the sliding piece is effectively prevented from being damaged by collision with the front stop block or the rear stop block.

At least one proximity sensor can be respectively arranged on two sides of the front stop block and the rear stop block. Therefore, the invention can detect the positions of the front stop block and the rear stop block in real time, confirm whether linear displacement is generated synchronously along with the rotation of the rotating shaft, prevent the device from generating abnormal state and control the dynamic test module to stop at any time.

The front block and the rear block can be respectively provided with at least one contact inductor. Therefore, when the sliding piece touches the contact sensors on the front stop block and the rear stop block, the sliding piece can send out a signal prompt in time, so that the generation of additional impact force is avoided, and the service life of the over-rotation limiting mechanism and the dynamic test module is prolonged.

The rotating shaft can be further sleeved with a brake module. Therefore, the rotating speed of the rotating shaft can be adjusted through the action of decelerating the rotating shaft by the brake module.

Please refer to fig. 3 and fig. 4, which are a partially exploded view and a top view of the over-rotation limiting mechanism according to a preferred embodiment of the present invention. In the embodiment, the over-rotation limiting mechanism 3 mainly includes a rotating shaft 31, a base 32 and a brake module 6 sleeved on the base 32, the rotating shaft 31 has a plurality of guiding slots 311, and is connected to the dynamic turnover mechanism 2 to enable the two mechanisms to rotate synchronously, the rotational kinetic energy of the rotating shaft 31 and the dynamic turnover mechanism 2 is supplied by the driving module 7, and the braking force of the rotating shaft 31 and the dynamic turnover mechanism 2 is generated by the brake module 6, and the rotation rate of the rotating shaft 31 can be adjusted according to the requirement. The base 32 is erected above the rotating shaft 31, and is provided with a slide rail 321, and a front block 33, a rear block 34 and a sliding member 35 are carried above the slide rail 321. In the embodiment, the front block 33 and the rear block 34 are adjustable blocks, and are positioned at specific positions of the slide rail 321 according to different requirements, and have four locking members 331, 341, which are respectively and correspondingly locked in the positioning holes 322 formed in the slide rail 321 at the specific positions. Therefore, the design is helpful for adjusting and fixing the front and rear stoppers 33 and 34, so that a user can conveniently set the limit rotation angle of the dynamic test module 1, and the flat cable is prevented from being pulled by the driving module due to over rotation.

In addition, the sliding member 35 is provided with a guide post 351, and the guide post 351 is accommodated in the guide slot 311 and can perform a guiding action along the guide slot 311. The sliding member 35 is slidably disposed on the sliding rail 321 by two sliding blocks 352, so that the sliding member 35 can be guided by the guiding groove 311 and can linearly slide on the sliding rail 321. Please refer to fig. 5A and fig. 5B, which are cross-sectional views of the mechanism for limiting over-rotation according to a preferred embodiment of the present invention, that is, when the rotating shaft 31 rotates, the sliding member 35 is guided by the guide post 351 and can slide toward the front block 33 or the rear block 34 according to the rotation direction of the rotating shaft 31, the sliding member 35 in fig. 5A moves to the position of the rear block 34, and the sliding member 35 in fig. 5B moves to the position of the front block 33.

Furthermore, referring back to fig. 4 and please refer to fig. 7, in the present embodiment, besides the front stop 33 and the rear stop 34 are used as the blocking protection blocks when the dynamic turnover mechanism 2 rotates excessively, the two sides of the front stop 33 and the rear stop 34 are respectively provided with four proximity sensors 51, so that the positions of the front stop 33 and the rear stop 34 can be detected in real time, and it is determined whether the sliding member 35 synchronously generates linear displacement along with the rotation of the rotating shaft 31, as shown in fig. 7, if a controller 8 receives signals sent by the four proximity sensors 51, it means that the four proximity sensors 51 do not detect the positions of the sliding member 35 to the front stop 33 and the rear stop 33, 34, the controller 8 sends a signal to notify the driving module 7 to stop rotating the dynamic turnover mechanism 2, and the controller 8 starts the braking module 6, so as to control the dynamic testing module 1 to stop in real time. In addition, in order to further reduce the impact force of the sliding member 35 on the front block 33 and the rear block 34, the present invention further provides a contact sensor 52 and a hydraulic buffer 4 on the front block 33 and the rear block 34, respectively. Therefore, when the sliding member 35 touches the contact sensors 52 on the front stop 33 and the rear stop 34, a signal can be sent to notify the controller 8 immediately, the driving module 7 stops providing the rotating power to the dynamic turnover mechanism 2, and the controller 8 also starts the braking module 6 to stop the dynamic turnover mechanism 2 immediately, so as to prevent the dynamic turnover mechanism 2 from pulling and winding displacement due to over-rotation, and prevent the generation of extra impact force, and if some impact force is applied to the front stop 33 or the rear stop 34, the solution can be absorbed by the oil pressure buffer 4, thereby prolonging the service life of the over-rotation mechanism 3 and the dynamic testing module 1.

Please refer to fig. 6A and fig. 6B, which are schematic cross-sectional views illustrating adjustment of the front and rear stops of the over-rotation limiting mechanism according to a preferred embodiment of the present invention.
