When the disk 397 rotates, the top shaft 301 slides in the V-shaped groove 399, gradually changing the distance between the top shaft 301 and the axis of the disk 397, thereby controlling the lifting and lowering movement of the top shaft 301.

[0059] Guide grooves 302 are provided on both sides of the detection rod 30 , and the guide grooves 302 are slidably connected to the guide rails 390 to guide the movement of the detection rod 30 .

A triangular plate 307 is fixedly provided on one side of the moving plate 306, and a roller 308 is rotatably provided on one side of the triangular plate 307.

[0061] When the roller 308 moves on the surface of the blowing plate, when a bulge appears on the surface of the blowing plate, the roller 308 pushes the moving plate 306 to move upward, and the distance sensor 305 detects that the distance of the moving plate 306 is shortened, thereby detecting the flatness of the surface of the blowing plate.

[0062] like Fig.12 , Fig.13 As shown, the base 4 includes a fixed base 41, on which a cylinder five 42 is fastened and installed, a sealing plate 43 is fixedly connected to the output end of the cylinder five 42, the sealing plate 43 is fixedly provided with symmetrically distributed air nozzles 44, the air nozzles 44 are fixedly connected to an air pipe 45, a supporting block 46 is fixedly provided on the sealing plate 43, a rectangular tube 47 is fixedly provided on the top of the supporting block 46, both sides of the rectangular tube 47 are respectively fixedly connected to the air pipe 45, the rectangular tube 47 is connected to an air outlet pipe 49, a cylinder six 48 is fixedly provided at one end of the rectangular tube 47, and an air pressure sensor 40 is fixedly provided at the other end.

[0063] In this embodiment, the pressure sensor and the air pressure sensor 40 both adopt the model FSR-A406, the visual sensor 392 adopts the model MV-SC3016C-12M-WBN, and the distance sensor 305 adopts the model SW-E60.

[0064] The output end of the cylinder 6 48 is fixed with a piston, which is slidably arranged between the rectangular tube 47 and the connecting part of the air outlet pipe 49 and the air pipe 45. When the blowing plate moves to one side of the base 4, the blowing plate is usually provided with a cooling water channel. The structure of the blowing plate is as follows: Fig.14 As shown, the sealing plate 43 is pushed to move by the cylinder five 42, so that the two air nozzles 44 block the water inlet and outlet of the water channel, connecting the water channel with the air pipe 45, and the cylinder six 48 pushes the piston to move to fill the water channel with gas, and the air pressure sensor 40 detects the pressure in the air pipe 45 and the water channel.

[0065] Here’s how it works:

[0066] After the automobile battery blown plate is prepared and formed, it is placed on the jig 2, and then the automobile battery blown plate is fixed by the limit plate 23, so that the blown plate is fixed on the pad 25, the jig 2 is moved to the top frame 13, the blown plate is pressed down by the pressing block, and then the air is exhausted by the air outlet groove 26 to detect the air tightness and pressure resistance of the blown plate.

[0067] At the same time, the two detection heads 208 are moved back and forth by the cooperation of the cylinder three 29 and the spring one 205, and the impact detection is performed on the inside of the inflation plate alternately to detect the compressive strength of the inside of the inflation plate.

[0068] After the internal pressure detection is completed, the sealing plate 43 is pushed to move by the cylinder five 42, so that the two air nozzles 44 block the water inlet and outlet of the water channel, connecting the water channel with the air pipe 45, and the cylinder six 48 pushes the piston to move to fill the water channel with gas. The air pressure sensor 40 detects the pressure in the air pipe 45 and the water channel.

[0069] By rotating the disk 397, the top shaft 301 slides in the V-shaped groove 399, gradually changing the distance between the top shaft 301 and the axis of the disk 397, thereby controlling the lifting and lowering movement of the top shaft 301, controlling the impact block 303 to impact the outer side of the blowing plate, and detecting the impact resistance of the blowing plate.

[0070] During this process, the pressure sensor 40 is used to constantly monitor whether there is a change in the pressure inside the inflation plate, and to detect the impact resistance of the water channel to avoid water leakage when the inflation plate is actually used.

[0071] During the external inspection process, the roller 308 translates on the surface of the blowing plate to detect whether there are protrusions on the surface of the blowing plate, and during the movement, the visual sensor 392 is used to detect whether there are concave points on the surface of the blowing plate, so as to detect the flatness of the appearance of the blowing plate.

[0072] When the detection is completed, the cylinder 6 48 pulls the piston to move, and the gas is discharged from the outlet pipe 49, and the outlet pipe 49 is directed to the top of the blowing plate to clean the surface of the blowing plate, which is helpful for subsequent packaging and sales.

[0073] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
