The end is connected to the first slide 3241-2; several first water injection blocks 3241-3 are distributed and installed above the first slide 3241-2; the upper pressing assembly 3242 includes a fixed frame 3242-1, a second cylinder 3242-2 and a pressure plate 3242-3; the fixed frame 3242-1 is fixed on the machine housing 1; the pressure plate 3242-3 is slidably connected to the fixed frame 3242-1 and located above the lower water injection assembly 3241; the second cylinder 3242-2 is fixed on the fixed frame 3242-1 and its power output end is connected to the pressure plate 3242-3; the feeding device 325 is arranged between the first barcode scanning device 322 and the air knife 3. Between 23 and the initial inspection and testing device 324, there is a second mounting bracket 3251, a second Y-axis drive device 3252, and a feeding plate 3253; the second mounting bracket 3251 is fixed on the chassis 1; the feeding plate 3253 is slidably connected to the second mounting bracket 3251; the height of the feeding plate 3253 is above the OK replenishing device 321, the first scanning device 322, the air knife 323 and the lower water injection assembly 3241 and below the pressure plate 3242-3; the feeding plate 3253 has a plurality of first positioning grooves 3253-1 distributed left and right; the middle of the first positioning groove 3253-1 has a first through hole 3253-2;The second Y-axis drive device 3252 is mounted on the second mounting bracket 3251 and its power output end is connected to the feeding plate 3253.

The air pressure test can determine the initial waterproofing effect of the explosion-proof valve. If the air pressure is stable, the initial inspection is OK; if the air pressure drops, it is considered NG (not acceptable). The initial inspection test device 324 is reset, and the second Y-axis drive device 3252 controls the feeding plate 3253 to be transported above the air knife 323.

This provides sufficient material for subsequent re-inspection. OK materials are manually added to the OK material carrier 3212 via the OK replenishment device 321. After the first X-axis module 3211 controls the OK material carrier 3212 to move to the left, manual replenishment is possible.

The lifting drive device 4231 is mounted on the housing 1 and its power output end is connected to the lifting movable frame 4232. The support plate 4233 is fixed to the lower part of the lifting movable frame 4232. The support plate 4233 has several support parts arranged on the left and right sides and drainage grooves 4233-1 located on the front and rear sides of the support parts. The front and rear sides of the support plate 4233 are provided with drainage interfaces 4233-2 communicating with the drainage grooves 4233-1. Each support part is provided with a second through hole 4233-3 and a sixth cylinder 4236 located on the second through hole 4233-4234. Two first positioning posts 4233-4 on the front and rear sides of 233-3; the movable plate 4234 is slidably connected to the upper part of the lifting movable frame 4232; the number of the second water injection blocks 4235 is the same as that of the support part; the second water injection blocks 4235 are fixed to the bottom of the movable plate 4234 and respectively correspond to the upper part of the support part; the sixth cylinder 4236 is installed above the lifting movable frame 4232 and its power output end is connected to the movable plate 4234; the test paper detection device 424 includes a test paper feeding assembly 4241, a test paper winding assembly 4242 and a test paper CCD imaging device 4243 installed on the chassis 1; the test paper feeding assembly 4241 and the test paper winding assembly 4242 are respectively located on the left and right sides of the waterproof re-inspection device 423;The test strip CCD imaging device 4243 is located between the waterproof re-inspection device 423 and the test strip winding assembly 4242;

[0045] The re-inspection module 4 also includes a second barcode scanning device 425; the second barcode scanning device 425 is installed on the front side of one of the waterproof re-inspection mechanisms 42, including a third X-axis module 4251 and a second barcode scanner 4252; the third X-axis module 4251 is installed on the chassis 1 and its power output end is connected to the second barcode scanner 4252. The two sets of waterproof re-inspection mechanisms 42 facing each other share one set of second barcode scanning device 425. The re-inspection loading and unloading conveying mechanism 41 transports the product to the top of the second barcode scanning device 425. The third X-axis module 4251 controls the movement of the second barcode scanner 4252 to scan the products on the re-inspection loading and unloading conveying mechanism 41 one by one. After scanning, the re-inspection loading and unloading conveying mechanism 41 will transport the product to the top of the second barcode scanning device 425. The product is placed on the adsorption seat 4215-1 of the flip-feeding device 421, where it is adsorbed and fixed. Then, the rotation drive device 4213 controls the swing frame 4214 to rotate 180° backward, and the fourth cylinder 4211 controls the third slide to move backward, delivering the product to the position of the waterproof re-inspection device 423. Because the product has protruding pillars, before the flip-feeding device 421 delivers the product, the lifting drive device 4231 of the waterproof re-inspection device 423 first controls the lifting movable frame 4232 to move downward. After the flip-feeding device 421 delivers the product, the lifting drive device 4231 then controls the lifting movable frame 4232 to move upward, receiving the product through the support plate 4233. After receiving the product on the auxiliary seat 4215-1, the lifting frame 4232 is controlled to move downwards, the flipping and feeding device 421 is reset, the sixth cylinder 4236 controls the moving plate 4234 to move downwards, the second water injection block 4235 is pressed on top of the product, and the second water injection block 4235 is connected to an external water supply device through a water pipe to inject water. The water injection time is maintained at about 30 seconds. If the waterproof performance of the explosion-proof valve is not up to standard, water will pass through the explosion-proof valve and hang at the bottom in the form of water droplets. The lifting drive device 4231 controls the lifting frame 4232 to move up and down to shake off the water droplets. The water falling onto the test paper will cause the test paper to change color. The color of the test paper can be observed through the test paper CCD imaging device 4243 to determine the corresponding product. The waterproof performance of the product can determine whether it is an OK product or an NG product. After the test is completed, the sixth cylinder 4236 drives the movable plate 4234 to rise, and the water in the second water injection block 4235 flows down to the drainage trough 4233-1 and is sent out from the drainage port 4233-2. The flipping and feeding device 421 takes the product from the waterproof re-inspection device 423 and places the OK product on the buffer material carrier plate 4222. The NG product is placed on the NG unloading conveyor belt device 22 and sent out. The OK material on the buffer material carrier plate 4222 is used to place it on the next material carrier plate 23. This can realize that when taking material from the material carrier plate 23 for inspection, the OK material on the buffer material carrier plate 4222 is unloaded onto the material carrier plate 23.

[0046] The swing arm 4215, the support part, and the second water injection block 4235 are all provided in five units; the buffer material carrier plate 4222 is provided with five placement positions; each placement position is provided with a clearance hole 4222-1 and a second positioning post 4222-2 located on the front and rear sides of the clearance hole 4222-1, so as to simultaneously detect five products. The clearance hole 4222-1 is used to prevent the protrusion on the product from being exposed, and the second positioning post 4222-2 positions the product.

[0047] The test strip detection device 424 further includes a first roll material buffer assembly 4244, a second roll material buffer assembly 4245, and a test strip punching assembly 4246 installed on the chassis 1. The first roll material buffer assembly 4244 and the test strip punching assembly 4246 are sequentially arranged between the test strip feeding assembly 4241 and the waterproof re-inspection device 423. The second roll material buffer assembly 4245 is arranged between the test strip CCD imaging device 4243 and the test strip winding assembly 4242. The arrangement of the first roll material buffer assembly 4244 and the second roll material buffer assembly 4245 allows for more flexible feeding and winding of the test strip. The test strip punching assembly 4246 punches holes in the test strip, and the punched holes are used to avoid the protrusion in the middle of the product. The protrusion passes through the hole in the test strip, which allows the product to be closer to the test strip and improves the stability of the detection.

[0048] The above description is not intended to limit the scope of the present invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the present invention.
