[0022] Hereinafter, the present invention will be further described with reference to the drawings and specific implementations:
[0023] Such as Figure 1-4 The tool shown for compression testing includes a body 10, a mounting frame 30, a turntable 20, a mounting frame drive mechanism 40, and a turntable drive mechanism 50. The mounting frame 30 is mounted on the body 10, and the mounting frame 30 The bottom end is formed as a pressing station, which is used to install an external test fixture. In addition, the turntable 20 is pivotally connected to the body 10, and the turntable 20 is located below the mounting frame 30. A positioning station is provided on the turntable 20, and the positioning station is used to install an external positioning jig. The above-mentioned mounting frame drive mechanism 40 can drive the mounting frame 30 to move along the height direction of the body 10, and the turntable drive mechanism 50 can drive the turntable 20 to rotate.
[0024] On the basis of the above structure, using the tool for pressing test of the present invention, taking the test circuit board as an example, the pressing station of the mounting frame 30 is equipped with a test fixture for testing the circuit board, which can be passed through the turntable The drive mechanism 50 drives the turntable 20 to rotate. The positioning station on the turntable 20 rotates to the outside of the pressing station. Then a positioning jig is installed on the positioning station. The circuit board is installed on the positioning jig. After the circuit board is positioned, the turntable The drive mechanism 50 can drive the turntable 20 to rotate so that the positioning station corresponds to the pressing station at the bottom end of the mounting frame 30. At this time, the mounting frame drive mechanism 40 drives the mounting frame 30 to move downwards to press the test probes of the test fixture. Put it on the circuit board of the positioning fixture for testing.
[0025] After the test is completed, the mounting frame drive mechanism 40 drives the mounting frame 30 to move upward, the turntable drive mechanism 50 drives the turntable 20 to rotate, the positioning jig of the positioning station rotates to the outside of the pressing station, the circuit board is removed, and the next round test. In this way, each time the workpiece is picked and placed is outside the pressing station to avoid interference. In addition, when applied to different workpiece tests, different test fixtures and positioning fixtures can be installed, and the driving mechanism required for pressing is the same, which is convenient for direct drive and has a wider range of use.
[0026] It should be noted that threaded holes can be provided on the mounting frame 30 and the turntable 20, and the test fixture and the positioning fixture can be fixed in the threaded holes by bolts, which is convenient for detachable installation.
[0027] Further, specifically, a first limit block 11 is fixedly connected to the body 10, and a second limit block 22 is correspondingly provided on the turntable 20. When the turntable 20 rotates until the positioning station corresponds to the pressing station, the turntable 20 The second limiting block 22 can abut the first limiting block 11. In this way, during the test, the turntable 20 rotates, and when the positioning station on the turntable 20 corresponds to the pressing station, the second limit block 22 on the turntable 20 can abut the first limit block 11 to prevent the turntable 20 from rotating Excessively, the positioning station and the pressing station on the turntable 20 can be accurately positioned.
[0028] More specifically, two positioning stations may be provided on the turntable 20, and the two positioning stations are arranged on the turntable 20 at intervals. Correspondingly, two first limit blocks 11 are provided on the body 10, and the two first limit blocks 11 are arranged at intervals on the rotation track of the turntable 20. In this way, during the test, a positioning jig is installed at one of the positioning stations to position the circuit board. After that, the turntable 20 rotates in one direction, and the second limit block 22 on the turntable 20 and one of the first on the body 10 The limit block 11 abuts, at this time, the positioning jig of the positioning station corresponds to the pressing station of the mounting frame 30, and the other positioning station is located outside the pressing station, and the next positioning jig is installed and Positioning preparation of the circuit board.
[0029] After the previous circuit board test is completed, the turntable 20 can be rotated in the reverse direction, and the second limit block 22 of the turntable 20 can abut another first limit block 11. At this time, the next positioning jig can be rotated to press Below the bonding station, and the positioning jig completed in the previous test is located outside the bonding station, which can be used to unload the circuit board. Such reciprocation improves the test efficiency and test accuracy.
[0030] Further, a camera may be provided on the top of the mounting frame 30, and the camera is used to collect workpiece information. Thus, before each test operation, the two-dimensional code of the workpiece on the turntable 20 can be checked by the camera on the mounting frame 30. Or take a photo with a bar code to obtain the corresponding product information for easy recording.
[0031] Further, the body 10 can also be provided with an anti-overpressure bracket 12, which is arranged below the turntable 20 and is arranged corresponding to the pressing station, that is, the positioning station on the turntable 20 rotates to When corresponding to the pressing station, during the downward pressing of the mounting frame 30, the pressure on the turntable 20 can be borne by the overpressure prevention bracket 12 under the turntable 20 to prevent the turntable 20 from being deformed under pressure.
[0032] Further, in order to facilitate the installation of the external positioning jig, a mounting groove 21 may be provided on the turntable 20, and the mounting groove 21 is formed as a positioning station. When the positioning jig is installed, the positioning jig can be installed in the mounting groove 21 , Easy to install accurately.
[0033] Further, the above-mentioned mounting frame driving mechanism 40 includes a driving cylinder 41, the cylinder of the driving cylinder 41 is fixed to the body 10, and the top end of the piston rod of the driving cylinder 41 is fixed to the mounting frame 30, so that the piston of the driving cylinder 41 The telescopic rod can drive the mounting frame 30 up and down stably.
[0034] Of course, the mounting frame drive mechanism 40 can also be implemented by other linear motion output mechanisms such as a screw drive mechanism and a linear motor in the prior art.
[0035] More specifically, the mounting frame drive mechanism 40 further includes a guide assembly for guiding the mounting frame 30 to move in the height direction of the body 10, the guide assembly may include a guide sleeve 42 and a guide rod 43, and the guide sleeve 42 and the mounting frame 30 With fixed connection, the guide rod 43 is fixed to the machine body 10, the mounting frame 30 moves up and down, and the guide sleeve 42 and the guide rod 43 are slidably matched to guide the mounting frame 30 up and down stably.
[0036] Further, the turntable driving mechanism 50 in this embodiment includes a rotary cylinder, and the rotary disk 20 is synchronously connected with the piston rod of the rotary cylinder. The rotary cylinder can drive the rotary disk 20 to rotate. Since the rotary cylinder is driven by pneumatic, it can start slowly and Stop slowly, with a certain buffer effect.
[0037] For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
