[0034] Specifically: Figure 2 As shown, the loading unit 2 includes a No. 1 frame 21, a No. 1 material bin 22 arranged on the No. 1 frame 21, a precision positioning mechanism 23 arranged on the No. 1 frame 21, a No. 1 conveyor line 24 arranged on the No. 1 frame 21 along the X direction, a No. 1 transfer mechanism 25 arranged on the No. 1 frame 21, and a flattening mechanism 26 arranged on the No. 1 frame 21 for pressing the gasket 100 in the jig 1 on the No. 1 conveyor line 24. Figure 3 As shown, the precision positioning mechanism 23 includes a No. 1 seat 231 arranged on the No. 1 frame 21, a plurality of No. 1 supporting seats 232 arranged along the Y direction on the No. 1 seat 231, and a No. 1 clamping cylinder 233 arranged on the No. 1 seat 231 and corresponding to the No. 1 supporting seat 232 one by one. After the gasket 100 is placed on the No. 1 supporting seat 232, the two claws of the No. 1 clamping cylinder 233 align the gasket 100.

[0035] In actual use, the gasket 100 in the No. 1 hopper 22 is transferred to the fine positioning mechanism 23 through the No. 1 transfer mechanism 25, and the two ends of the gasket 100 on the No. 1 support seat 232 are corrected by the two claws of the No. 1 clamping cylinder 233 to achieve fine positioning, and then the No. 1 transfer mechanism 25 transfers the gasket 100 from the No. 1 support seat 232 to the fixture 1.

[0036] In the above design, the structural design and specific implementation of the feeding unit 2 facilitate rapid feeding of the gasket 100 .

[0037] Specifically: Figure 2 As shown, the No. 1 transfer mechanism 25 includes a No. 1 support 251 disposed on the No. 1 frame 21, a No. 1 linear module A252 disposed on the No. 1 support 251 along the Y direction, a No. 1 linear module B253 fixedly disposed at the output end of the No. 1 linear module A252 along the Z direction, a No. 1 connecting plate 254 fixedly disposed at the output end of the No. 1 linear module B253, and a plurality of No. 1 suction cups 255 arranged on the No. 1 connecting plate 254 along the Y direction. Figure 4As shown, the flattening mechanism 26 includes a plurality of pressing heads 261, a No. 1 mounting seat 262 arranged on the No. 1 frame 21, a No. 1 cylinder 263 vertically arranged on the No. 1 mounting seat 262, a No. 1 plate fixedly arranged at the output end of the No. 1 cylinder 263, and a plurality of elastic buffer members 264 arranged on the No. 1 plate and connected to the upper end of the pressing head 261.

[0038] In actual use, the No. 1 linear module A252 drives the No. 1 linear module B253 to move back and forth between the silo and the No. 1 conveyor line 24 along the Y direction, and the No. 1 connecting plate 254 is driven to rise and fall by the No. 1 linear module B253, so that the No. 1 suction cups 255 move synchronously. When it is necessary to flatten the gasket 100 in the jig 1, the No. 1 plate is driven downward by the No. 1 cylinder 263, so that the pressure head 261 contacts the gasket 100, and the elastic buffer 264 is compressed with the continuous driving of the No. 1 cylinder 263 until the pressure head 261 completes the pressing of the gasket 100.

[0039] In the above design, the structural design and specific implementation method of the No. 1 transfer mechanism 25 can effectively realize the rapid pressing of the gasket 100.

[0040] Specifically: Figure 5 As shown, the code scanning and code checking unit 3 includes a No. 2 frame 31, a No. 2 conveyor line 32 arranged on the No. 2 frame 31 along the X direction and connected to the No. 1 conveyor line 24, a marking component 33, a code scanning component 34, a code checking component 35, a No. 2 destruction component and a No. 2 transfer mechanism 37 arranged on the No. 2 frame 31, the marking component 33, the code scanning component 34, the code checking component 35, the No. 2 destruction component and the No. 2 transfer mechanism 37 are arranged along the X direction and are all located on one side of the No. 2 conveyor line 32, the marking component 33 is used to draw a two-dimensional code on the gasket 100, the code scanning component 34 is used to detect whether the second number can be scanned normally, the code checking component 35 is used to detect the code deviation of the two-dimensional code, and the No. 2 transfer mechanism 37 is used to transfer the gasket 100 with an unqualified two-dimensional code to the No. 2 destruction component for destruction.

[0041] In actual use, after the jig 1 enters the No. 2 conveyor line 32 from the No. 1 conveyor line 24, the gasket 100 in the jig 1 is laser marked by the marking component 33, and the marked two-dimensional code is read by the code scanning component 34. If the two-dimensional code can be read normally, it is qualified, otherwise it is unqualified. The code detection component 35 is used to check the code deviation of the two-dimensional code. The gasket 100 that fails the inspection by the code scanning component 34 or the code detection component 35 is transferred to the No. 2 destruction component by the No. 2 transfer mechanism 37 for destruction, and the gasket 100 that passes the code scanning component 34 and the code detection component 35 flows into the size detection unit 4 along the No. 2 conveyor line 32.

[0042] In the above design, the structural design of the code scanning and checking unit 3 is convenient for drawing a two-dimensional code on the gasket 100 and automatically checking the two-dimensional code.

[0043] Specifically: Figure 5 As shown, the No. 2 transfer mechanism 37 includes a No. 2 mounting seat 371 arranged on the No. 2 frame 31, a No. 2 linear module A372 arranged on the No. 2 mounting seat 371, a No. 2 linear module B373 fixedly arranged at the output end of the No. 2 linear module A372 along the Z direction, a No. 2 plate arranged at the output end of the No. 2 linear module B373, and a plurality of clamps 374 fixedly arranged on the No. 2 plate.

[0044] In actual use, the No. 2 linear module A372 drives the No. 2 linear module B373 to move the No. 2 plate, so that the clamping claws 374 on the No. 2 plate transfer the unqualified gasket 100 in the fixture 1 to the No. 2 destruction assembly for destruction.

[0045] Specifically: Figure 6 As shown, the size detection unit 4 includes a No. 3 frame 41, a No. 3 conveyor line 42 arranged on the No. 3 frame 41 along the X direction, a transverse transport mechanism 43 arranged on the No. 3 frame 41, a transfer transport mechanism 44 arranged on the No. 3 frame 41, an inspection mechanism 45 arranged on the No. 3 frame 41, and a No. 3 destruction component 46 arranged on the No. 3 frame 41, the transfer transport mechanism 44 is used to transfer the products in the No. 3 conveyor line 42 to the transfer to the transverse transport mechanism 43, the transverse transport mechanism 43 is used to transport the products to the inspection mechanism 45 for inspection, the inspection mechanism 45 is used to perform size inspection and penetration shortage inspection on the products, and the No. 3 destruction component 46 is used to scrap the products that fail the shortage inspection.

[0046] In actual use, the jig 1 in the No. 2 conveyor line 32 is received by the No. 3 conveyor line 42, and then the gasket 100 in the jig 1 is transferred to the transverse conveying mechanism 43 by the transfer conveying mechanism 44, and the gasket 100 is moved to the detection position of the inspection mechanism 45 for inspection by the transverse conveying mechanism 43. When the inspection mechanism 45 passes the inspection, the gasket 100 is transferred back to the jig 1 by the transfer conveying mechanism 44. If the inspection mechanism 45 fails the inspection, the gasket 100 is transferred to the No. 3 destruction component 46 by the transfer conveying mechanism 44.

[0047] In the above design, the structural design and specific implementation of the size detection unit 4 can quickly detect the size of the gasket 100.

[0048] Specifically: the No. 2 destruction component and the No. 3 destruction component 46 have the same structure, and the No. 3 destruction component 46 includes a No. 3 cylinder A fixedly set on the No. 3 frame 41, a No. 3 plywood A set at the output end of the No. 3 cylinder A, a No. 3 cylinder B set on the No. 3 frame 41, and a No. 3 plywood B fixedly set at the output end of the No. 3 cylinder B, and the No. 3 plywood A and the No. 3 plywood B are arranged opposite to each other.

[0049] In actual use, the unqualified gasket 100 is placed between the No. 3 plywood A and the No. 3 plywood B, and then the No. 3 cylinder A and the No. 3 cylinder B respectively drive the No. 3 plywood A and the No. 3 plywood B to move towards each other to squeeze the gasket 100, thereby destroying the gasket 100.

[0050] In the above design, the structural design and specific implementation of the No. 2 destroying component 46 and the No. 3 destroying component 46 facilitate the rapid destruction of the defective gasket 100 .

[0056] The method for coding and inspecting the size of the gasket 100 adopts the flexible line for coding and inspecting the size of the gasket 100, provides the gasket 100 to the jig 1 through the feeding unit 2, and transports the jig 1 to the code scanning and inspection unit 3, the code scanning and inspection unit 3 draws a two-dimensional code on the gasket 100 in the jig 1 and detects the two-dimensional code, detects the size of the gasket 100 through the size detection unit 4, and unloads the gasket 100 through the unloading unit 5.
