[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0026] See also Figures 1 to 5The utility model provides an AOI inspection mechanism with a shock-absorbing function, comprising a base 1, a gravity plate 2, a detection table 3, a connecting piece 4, an airbag assembly 5 and a transfer device 6;

[0027] The gravity plate 2 is connected to the base 1 via a connector 4. The gravity plate 2 is spaced apart from the base 1. Both ends of the airbag assembly 5 are connected to the gravity plate 2 and the base 1, respectively. The height of the airbag assembly 5 before inflation is less than the height of the connector 4. The height of the airbag assembly 5 after inflation is greater than the height of the connector 4.

[0028] The detection platform 3 is arranged on the gravity plate 2 and is far away from the base 1;

[0029] The transfer device 6 is disposed on the base 1 and is used to transfer external objects to be inspected to the inspection platform 3 .

[0030] Specifically, in the present embodiment, the base 1 is fixed on the workshop floor, and a transfer device 6 and a gravity plate 2 are installed on the upper surface of the base 1. The transfer device 6 is used to transfer the electronic PCB board to be tested. Four connectors 4 and four airbag assemblies 5 are installed on the upper surface of the base 1. Each connector 4 includes an adjustable screw and a tray fixed on the screw. The tray fits the lower surface of the gravity plate 2 to support the gravity plate 2. The gravity plate 2 adopts a plate with a higher density such as marble or granite to increase stability. The four airbag assemblies 5 are symmetrically distributed at the four corners of the gravity plate 2. When the airbag assemblies 5 are filled with high-pressure gas, the gravity plate 2 is supported by the four airbag assemblies 5, so that the gravity plate 2 loses its connection with the connector 4, thereby avoiding the phenomenon that the reaction force generated by the transfer device 6 during the working process acts on the base 1 and then is transmitted to the gravity plate 2, thereby ensuring the relative static state of the detection platform 3, thereby ensuring the detection quality.

[0031] By setting up an AOI inspection mechanism with a shock-absorbing function composed of a base 1, a gravity plate 2, a test table 3, a connector 4, an airbag assembly 5 and a transfer device 6, under the action of the airbag assembly 5, it is ensured that the test table 3 is in a relatively static state during the working process, thereby improving the inspection quality and meeting the production requirements.

[0032] The transfer device 6 includes a support column 61, a suspension beam 62 and an adsorption assembly 63. The support column 61 is arranged on the base 1, the suspension beam 62 is connected to the support column 61, the suspension beam 62 is located above the detection platform 3, the adsorption assembly 63 is slidably connected to the suspension beam 62, and the adsorption assembly 63 is used to transfer external parts to be inspected to the detection platform 3. The support column 61 adopts a hollow square column structure, the suspension beam 62 interviews a square steel structure, and the adsorption assembly 63 is slidably connected to the suspension beam 62 to transfer external electronic PCB boards to the detection platform 3.

[0033] The airbag assembly 5 includes a bottom plate 51, a side plate 52, a top plate 53 and a bladder body 54. The bottom plate 51, the side plate 52 and the top plate 53 are connected in sequence to form an accommodating cavity. The bladder body 54 is located in the accommodating cavity. The bottom plate 51 is connected to the base 1, and the top plate 53 is connected to the gravity plate 2. The bottom plate 51, the side plate 52 and the top plate 53 form a U-shaped part. The upper end of the bladder body 54 abuts the top plate 53, and the lower end of the bladder body 54 abuts the bottom plate 51. After the bladder body 54 is filled with high-pressure gas, the top plate 53 is lifted up, so that the height of the bottom plate 51 and the top plate 53 is increased. The supporting force of the gravity plate 2 is on the top plate 53, reducing the effect of the connecting member 4 on the gravity plate 2.

[0034] The airbag assembly 5 also includes an airbag regulating valve for adjusting the bag body 54, which is used to adjust the horizontal plane of the gravity plate 2 to further improve the production quality.

[0035] The detection platform 3 includes a platform 31 and a plurality of adjustment rods 32. The platform 31 is connected to the gravity plate 2 via the plurality of adjustment rods 32. The platform 31 and the gravity plate 2 are arranged in parallel with each other, so as to facilitate the adjustment of the plane levelness of the detection platform 3 and further improve the detection quality.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
