Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

An embodiment of the terminal inspection device is shown in fig. 1 to 5, and includes a holder 10, a driving mechanism 20, a testing mechanism 30, and a terminal placing table 40; the support 10 is provided with a driving mechanism 20, the driving mechanism 20 is provided with a testing mechanism 30, the driving mechanism 20 is used for driving the testing mechanism 30 to move towards and away from the terminal placing table 40, the maximum stroke of the driving mechanism 20 for driving the testing mechanism 30 to move towards the terminal placing table 40 is a set value, and the terminal placing table 40 is used for placing a terminal 50 to be tested; the testing mechanism 30 includes an indicator 31, a power supply module 32 for supplying power to the indicator 31, and a test pogo pin 33 for switching the indicator 31 on and off with the power supply module 32; the test pogo pin 33 is disposed opposite to the terminal placing stage 40, and the pressed test pogo pin 33 is used to connect the indicator 31 and the power supply module 32 so that the indicator 31 sends an indication signal.

When the terminal testing device is applied, the terminal to be tested 50 needs to be placed on the terminal placing table 40, the PIN of the terminal to be tested 50 is arranged upwards, the driving mechanism 20 drives the testing mechanism 30 to move downwards until the driving mechanism 20 drives the testing mechanism 30 to move downwards to the maximum stroke, and the maximum downward movement stroke is set according to different types of terminals to be tested 50 to be tested; if the quality of the PIN of the terminal 50 to be tested is qualified, the PIN of the terminal 50 to be tested pushes the test spring PIN 33 to move until the test spring PIN 33 connects the power supply module 32 with the indicator 31, so that the indicator 31 sends out an indication signal to know the quality of the PIN of the terminal 50 to be tested is qualified; otherwise, if the PIN quality of the terminal 50 to be tested is not good, the PIN of the terminal 50 to be tested cannot push the test pogo PIN 33 to move to a proper position, and the power supply module 32 and the indicator 31 are in an open circuit state, that is, the PIN quality of the terminal 50 to be tested can be known by the fact that the indicator 31 cannot send an indication signal.

The above-mentioned testing mechanism 30 implements indication of the detection result by switching on and off the power supply loop, and a preferred way to implement this is shown in fig. 2 to 4, where the testing mechanism 30 further includes a first conductive block 341 and a second conductive block 342; the power supply module 32 is electrically connected to the indicator 31 through the first conductive block 341, the power supply module 32 is electrically connected to the testing pogo pin 33 through the second conductive block 342, the testing pogo pin 33 is opposite to the first conductive block 341, and the pressed testing pogo pin 33 can elastically abut against the first conductive block 341, so that the power supply module 32 supplies power to the indicator 31.

Therefore, when the PIN quality of the terminal 50 to be tested is not good, the testing elastic PIN 33 will be in an uncompressed state or an underpressurized state, and the testing elastic PIN 33 will be separated from the first conductive block 341, so that the power supply module 32 and the indicator 31 are in an open circuit state, and the indicator 31 cannot send an indication signal; when the PIN quality of the terminal 50 to be tested is qualified, the terminal 50 to be tested can push the testing elastic PIN 33 to elastically abut against the first conductive block 341, so as to connect the power supply loop between the power supply module 32 and the indicator 31, and the indicator 31 sends an indication signal to indicate the PIN quality of the terminal 50 to be tested is qualified.

The first conductive block 341 and the second conductive block 342 may be made of conductive metal, for example, the first conductive block 341 may be made of stainless steel, and the second conductive block 342 may be made of aluminum, so that the mechanical strength of the testing mechanism 30 is further improved on the basis of ensuring that the first conductive block 341 and the second conductive block 342 are conductive.

In addition, the power supply module 32 is used for providing electric energy for the testing mechanism 30, so the power supply module 32 may be powered by commercial power or a battery, and when the power supply module is powered by a battery, as shown in fig. 3 and 4, it is preferable that the power supply module 32 is provided with a loading area 321, the loading area 321 is exposed outside the testing mechanism 30, a battery 322 is installed in the loading area 321, and the battery 322 is used for providing electric energy for the testing mechanism 30; the advantage of this arrangement is that it is not limited by the location, the terminal detection device can be used anywhere, and the battery 322 can be replaced directly outside the testing mechanism 30, which also facilitates the replacement of the battery 322.

The driving mechanism 20 is used to drive the testing mechanism 30 to move towards and away from the terminal placing table 40, and the driving mechanism 20 may be controlled by a full-automatic control or a manual control.

One preferred way of manually controlling the driving mechanism 20 is shown in fig. 1 and 2, where the driving mechanism 20 includes a supporting frame 21, a handle 22, a connecting plate 23, a push rod 24 and a guide block 25; the support frame 21 is fixedly connected with the bracket 10; the handle 22 is rotatably connected with the support frame 21, so that the handle 22 can turn over by taking the rotary connection position as a rotary center; one side of the connecting plate 23 is rotationally connected with the handle 22, and the other side, opposite to the connecting plate 23, is rotationally connected with the push rod 24; the push rod 24 is fixedly connected with the testing mechanism 30; the guide block 25 is arranged on the support 10, the guide block 25 is used for limiting the moving track of the testing mechanism 30 to be a straight line, and the handle 22 is turned over to drive the push rod 24 to move linearly.

When the terminal placing table is applied, if the control handle 22 is turned upwards, the handle 22 can drive the testing mechanism 30 to move upwards through the connecting plate 23, so that the testing mechanism 30 is moved away from the terminal placing table 40, and a worker can place the terminal 50 to be tested on the terminal placing table 40 conveniently; if the control handle 22 is turned over downwards, the handle 22 can drive the testing mechanism 30 to move downwards through the connecting plate 23, so that the testing mechanism 30 moves towards the terminal placing table 40, and the detection of the terminal 50 to be tested is realized.

In addition, the guide block 25 is used to ensure that the testing mechanism 30 always moves linearly, and a preferred embodiment of the guide block 25 for achieving the purpose is shown in fig. 1 and 5, the guide block 25 encloses a limiting channel 251, the central axial direction of the limiting channel 251 is in the same direction with the moving track of the testing mechanism 30, and the testing mechanism 30 is movably installed in the limiting channel 251.

The guide block 25 is always surrounded outside the circumference of the test mechanism 30, thereby limiting the test mechanism 30 to move only in a straight line; further, the guide blocks 25 may be formed integrally, for example, the guide blocks 25 may be formed in a shape of "square", or as shown in fig. 1 and 5, the guide blocks 25 may be formed in two pieces, each of the guide blocks 25 being formed in a shape of "concave", so as to facilitate the assembly between the guide block 25 and the test mechanism 30.

Further, in order to realize that the maximum stroke of the driving mechanism 20 driving the testing mechanism 30 to move to the terminal placing table 40 is a set value, as shown in fig. 1, fig. 2 and fig. 5, the testing mechanism 30 may be provided with a protrusion 35, the protrusion 35 extends in a direction away from the central axial direction of the limiting channel 251, the guide block 25 is disposed between the protrusion 35 and the terminal placing table 40, and the abutment of the guide block 25 and the protrusion 35 is used for preventing the testing mechanism 30 from moving to the terminal placing table 40.

Therefore, no matter how the operator operates, the abutment of the bump 35 and the guide block 25 will prevent the testing mechanism 30 from moving further, which is beneficial to avoid the testing mechanism 30 from moving excessively to damage the terminal 50 to be tested, and also to ensure that the testing position of the testing elastic pin 33 is the same each time, so that the testing result of the terminal testing device is accurate and error-free.

It should be noted that, for different terminals 50 to be tested, the maximum downward moving stroke of the testing mechanism 30 needs to be adjusted to different values, and for this purpose, as shown in fig. 1 and fig. 5, a waist hole 11 for adjusting the installation position of the driving mechanism 20 may be provided on the bracket 10, the extending direction of the waist hole 11 matches the moving track of the testing mechanism 30, a locking member 12 for adjusting the installation position is installed in the waist hole 11, and the locking member 12 is connected with the driving mechanism 20 to fix the installation position of the driving mechanism 20.

The locking member 12 in this case may be a bolt, or a nut and screw combination; taking the locking member 12 as an example of a bolt, the driving mechanism 20 can be disposed on one surface of the bracket 10, the locking member 12 can be disposed on the other surface of the bracket 10 opposite to the driving mechanism 20, the locking member 12 can pass through the waist hole 11 to connect with the driving mechanism 20, so as to lock and fix the driving mechanism 20 on the bracket 10, if the installation position of the driving mechanism 20 needs to be adjusted, the locking member 12 can be unscrewed, and after the installation position of the driving mechanism 20 is adjusted, the driving mechanism 20 can be locked and fixed.

Since the terminal placement stage 40 is used to place the terminals 50 to be tested, but the shapes of the different terminals 50 to be tested are different from each other, in order to increase the application range of the terminal placement stage 40, as shown in fig. 1, a through groove 41 may be provided on a surface of the terminal placement stage 40 facing the test mechanism 30, the through groove 41 may penetrate the terminal placement stage 40, and a supporting step 42 may be provided on an inner wall of the through groove 41.

Therefore, when the terminal to be tested is applied, the terminal to be tested 50 can be supported on the supporting step 42, and the local part of the terminal to be tested 50 can pass through the through groove 41, that is, the terminal to be tested 50 with the matched size on the peripheral side can be placed on the terminal placing table 40, so that the application range of the terminal placing table 40 is expanded.

The indicator 31 is used for providing a visual indication result for the worker, so the indicator 31 can be set as an indicator light and/or a buzzer, that is, the worker can be provided with indication by the light emission of the indicator light and/or the sounding of the buzzer.

As shown in fig. 3 and 4, in this embodiment, the indicator 31 is preferably an indicator light, and a transparent cover plate 36 is disposed outside the testing mechanism 30, and the transparent cover plate 36 covers the indicator light; the indicator lamp has the advantages that the indication is clear and no environmental noise is generated, and the transparent cover plate 36 can cover and protect the indicator lamp, so that the service life of the indicator lamp is prolonged.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
