On the basis of the structure, when the full-automatic flexible circuit board testing machine is used, the feeding and discharging assembly 80 can clamp the flexible circuit board and place the flexible circuit board on the positioning assembly 20 for positioning, the turntable 40 drives the positioning assembly 20 to rotate to the lower side of the testing assembly 30, and the testing assembly 30 is in compression joint with the flexible circuit board on the positioning assembly 20 for electrical connection, and then testing is performed. After the test is completed, the turntable driving mechanism 50 drives the turntable 40 to rotate to the outer side of the test assembly 30, and the loading and unloading assembly 80 can take down the workpiece to complete the unloading, so that the test and loading and unloading are automatically completed. The turntable 40 can enable the positioning assembly 20 to reciprocally rotate below the testing assembly 30 and outside the testing assembly 30, so as to facilitate the picking and placing of the flexible circuit board.
Specifically, the positioning assembly 20 includes a positioning seat, a cover plate 23, and a cover plate driving mechanism, where the positioning seat is detachably mounted on the turntable 40. A positioning groove 21 is arranged on the positioning seat, and the positioning groove 21 is matched with the flexible circuit board structure. In addition, a connector groove 22 is provided in the positioning groove 21, and the connector groove 22 is used for accommodating a connector of the flexible circuit board. The cover plate 23 can move close to or away from the connector groove 22 under the driving of the cover plate driving mechanism, and the cover plate 23 is packaged on the connector groove 22 after moving close to the connector groove 22. Of course, electrical connector test lines may be provided within the connector slots 22.
The test assembly 30 can move along the height direction of the machine body 10, and the test assembly 30 is disposed above the positioning assembly 20. The test assembly 30 is used for being pressed onto the flexible circuit board in the positioning slot 21 after downward movement, and is electrically connected with the flexible circuit board for testing.
Based on the above structure, with the fully automatic flexible circuit board testing machine of the invention, the turntable 40 can rotate to the outer side of the machine body 10 under the drive of the turntable driving mechanism 50, and the flexible circuit board can be placed in the positioning groove 21 on the positioning seat, and can be initially positioned. At the same time, the electrical connector on the flexible circuit board can be correspondingly placed in the connector groove 22 on the bottom wall of the positioning groove 21, the electrical connector on the flexible circuit board can be electrically connected with the electrical connector test circuit, and the electrical connector on the flexible circuit board can be positioned. Then, the turntable driving mechanism 50 drives the turntable 40 to rotate, so that the positioning seat rotates below the testing assembly 30, at this time, the testing assembly 30 moves downwards along the height direction of the machine body 10, and when testing, the testing assembly 30 can move downwards and be pressed on the flexible circuit board for testing, and the degree of automation is higher. And during testing, the flexible circuit board and the connector can be positioned, so that the testing precision is improved.
After the test is completed, the test assembly 30 moves upward, the turntable driving mechanism 50 drives the turntable 40 to rotate, the positioning assembly 20 rotates to the outer side of the machine body 10, and the flexible circuit board is taken down for the next round of test. Thus, each time the workpiece is taken and placed outside the machine body 10, interference is avoided. In addition, when being applied to different work piece tests, dismantle the positioning seat, change the locating component 20 of different models, application scope is wider.
In this embodiment, one end of the cover plate 23 is formed as a capping end 231, the middle end of the cover plate 23 is hinged to the positioning seat, and the cover plate 23 can rotate under the driving of the cover plate driving mechanism, i.e. the capping end 231 rotates towards or away from the connector slot 22. When the cover plate 23 is driven to cover, the cover plate 23 can be driven to rotate by the cover plate driving mechanism, so that the cover end 231 of the cover plate 23 can rotate towards the position close to the connector groove 22, and the cover is covered on the connector groove 22. After the test is completed, the capping end 231 of the cap plate 23 can be rotated reversely, away from the connector slot 22, and the workpiece can be removed.
Specifically, the end of the cover 23 away from the cover end 231 is formed as a driving end 232, and the cover driving mechanism includes a first cylinder 24 and a second cylinder 34, so that the first cylinder 24 is fixedly connected to the positioning seat, and the piston rod of the first cylinder 24 can push the cover end 231 to rotate towards the connector slot 22 when moving towards the positioning slot 21. In addition, the cylinder body of the second cylinder 34 is fixedly connected to the testing assembly 30, and when the testing assembly 30 is used for downward movement, the piston rod of the second cylinder 34 can push the driving end 232 to rotate downwards so as to enable the sealing cover end 231 to rotate away from the connector groove 22.
Based on this structure, the cover plate 23 can be opened and closed by the second air cylinder 34 and the first air cylinder 24 respectively, specifically, when the cover is driven to cover the connector groove 22, the piston rod of the first air cylinder 24 can extend towards the connector groove 22, during the extending process, the piston rod of the first air cylinder 24 can push the cover end 231 forward to rotate downwards, and during the process, the cover end 231 can cover the connector groove 22. When the connector slot 22 is opened, the testing assembly 30 is pressed against the positioning seat at this time, so that the piston rod of the second air cylinder 34 extends downwards, and in the process that the piston rod of the second air cylinder 34 extends downwards, the driving end 232 can be pushed downwards to drive the capping end 231 to rotate upwards, so that the connector slot 22 is opened.
In order to facilitate better uncovering of the second cylinder 34, a mounting groove 25 may be provided on the positioning seat, the mounting groove 25 may be specifically located at one side of the positioning groove 21, the middle end of the cover plate 23 may be hinged to the top end of the mounting groove 25, the cover end 231 punishs the mounting groove 25, and the driving end 232 is located in the mounting groove 25, so that the driving end 232 may rotate in the mounting groove 25. Thus, when the test assembly 30 moves downwards during the uncapping process, the piston rod of the second cylinder 34 is used to be inserted into the mounting groove 25, the telescopic movement of the piston rod of the second cylinder 34 can be limited in the mounting groove 25, and under the guidance of the mounting groove 25, the piston rod of the second cylinder 34 extends out to stably drive the driving end 232 to rotate, so as to uncap.
It should be noted that, the cover plate driving mechanism in this embodiment is implemented by using the first air cylinder 24 and the second air cylinder 34 respectively disposed on the positioning seat and the testing seat 31, so that the installation space on the machine body 10 can be saved, and the separate air cylinders can be opened or closed only by one stroke cooperation, so that the movement space is saved, and the whole volume of the machine body 10 is smaller.
Of course, in other cases, in the absence of the second cylinder 34, a torsion spring may be provided between the cover plate 23 and the positioning seat, so that the return of the cover plate 23 may be achieved by an elastic member.
Further, in the present embodiment, the machine body 10 may further be provided with a mounting frame 60 and a mounting frame driving mechanism. The test assembly 30 includes a test socket 31 and a test probe 33, the test probe 33 is fixedly connected to the bottom end of the test socket 31, and the test socket 31 is detachably fixedly connected to the bottom end of the mounting frame 60. The mounting frame 60 moves in the height direction of the machine body 10 under the driving of the mounting frame driving mechanism.
So, after the flexible circuit board is positioned in the positioning groove 21, the mounting frame 60 can be driven to move downwards by the mounting frame driving mechanism, the test seat 31 arranged at the bottom end of the mounting frame 60 can move downwards, and the test probe 33 arranged at the bottom end of the test seat 31 can be electrically connected with the circuit of the flexible circuit board in the downward movement process, so that the test can be completed. After the test is completed, the mounting frame driving mechanism can drive the test seat 31 to move upwards, and the test seat 31 is separated from the positioning seat, so that the tested flexible circuit board can be taken down.
The test seat 31 and the mounting frame 60 are detachably mounted, so that the test assembly 30 can be replaced on circuit boards with different types, and the test range is wider.
Further, a positioning column 311 may be further disposed at the bottom end of the test seat 31, the positioning column 311 is mounted at the bottom end of the test seat 31 by an elastic component, a positioning hole is disposed on the positioning seat, and when the test seat 31 moves downward, the positioning seat can be inserted into the positioning hole, so that the test seat 31 is matched with the positioning seat in a positioning manner, and the accurate test of the test probe 33 is facilitated. And because the positioning column 311 is connected with the test seat 31 through the elastic component, the positioning column 311 has the degree of freedom of left and right deflection, and when the positioning column 311 is matched with the positioning seat, the positioning column 311 has a certain degree of freedom of swinging, so that when the flexible circuit board has deviation, the probe on the test seat 31 is correspondingly deflected, and the positioning is more accurate.
Further, the above-mentioned mounting bracket driving mechanism includes a third cylinder 32, the cylinder body of the third cylinder 32 is fixedly connected to the machine body 10, the top end of the piston rod of the third cylinder 32 is fixedly connected to the mounting bracket 60, so that the piston rod of the third cylinder 32 stretches and contracts to drive the mounting bracket 60 to be stable up and down.
Of course, the mounting frame driving mechanism can also be realized by other linear motion output mechanisms such as a screw rod transmission mechanism, a linear motor and the like in the prior art.
More specifically, the mounting frame driving mechanism further comprises a guiding component, the guiding component is used for guiding the test seat 31 to move in the height direction of the machine body 10, the guiding component can comprise a guiding sleeve 351 and a guiding rod 352, the guiding sleeve 351 is fixedly connected with the test seat 31, the guiding rod 352 is fixed with the positioning seat, the test seat 31 moves up and down, and the guiding sleeve 351 is in sliding fit with the guiding rod 352, so that the test seat 31 can be guided to stably move up and down.
Further, the two ends of the positioning slot 21 are respectively provided with a connector slot 22, the cover plate 23 is used for being packaged on one of the connector slots 22, a plurality of positioning pins 26 are arranged on the periphery of the other connector slot 22, pin holes 312 are correspondingly formed in the test seat 31, in the actual production process, connectors are mounted on the front and back sides of the flexible circuit board, the downward connector can be electrically connected with a test circuit in one of the connector slots 22 and is sealed by the cover plate 23, the upward connector can be limited and positioned by the positioning pins 26, the positioning pins 26 are inserted into the pin holes 312 in the test, the test probes 33 on the test seat 31 are convenient to test, and the positioning test is more accurate.
Further, specifically, the body 10 is fixedly connected with the first limiting block 11, and the turntable 40 is correspondingly provided with the second limiting block 42, and when the turntable 40 rotates to the position component 20 to correspond to the test component 30, the second limiting block 42 on the turntable 40 can be abutted with the first limiting block 11. Thus, when the turntable 40 rotates during testing, the second limiting block 42 on the turntable 40 can be abutted with the first limiting block 11 when the positioning component 20 on the turntable 40 corresponds to the testing component 30, so that the turntable 40 is prevented from rotating too far, and the positioning component 20 on the turntable 40 and the testing component 30 are accurately positioned.
More specifically, two positioning assemblies 20 may be provided on the turntable 40, the two positioning assemblies 20 being spaced apart on the turntable 40. Correspondingly, two first limiting blocks 11 are arranged on the machine body 10, and the two first limiting blocks 11 are arranged at intervals on the rotating track of the turntable 40. Thus, when testing is performed, the positioning assembly 20 is installed on one of the positioning assemblies 20 to perform circuit board positioning, after that, the turntable 40 rotates towards one direction, the second limiting block 42 on the turntable 40 is abutted against one of the first limiting blocks 11 on the machine body 10, at this time, the positioning assembly 20 of the positioning assembly 20 corresponds to the testing assembly 30 of the mounting frame 60, and the other positioning assembly 20 is located outside the testing assembly 30 to perform installation of the next positioning assembly 20 and positioning preparation of the circuit board.
