[0014] Preferably, a feed port is provided at the left end of the detection platform.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This instrument production waterproof test device is to put multiple groups of instruments into the transport frame in batches, and transport them to the right side by the transport frame. When the transport frame is placed under the water storage tank, the water inside the water storage tank is sprayed out through the nozzle to spray the instruments inside the transport frame. The excess water falls through the grid and enters the inside of the gutter. When the transport frame enters above the fan, the fan dries the remaining water inside the transport frame. When the transport frame finally moves to the top of the limit triangle plate, the grid is opened, and the instrument enters the inclined surface of the limit triangle plate and falls above the weight sensing device. The device is used to determine the weight of multiple groups of instruments. When the weight of the instrument batch is within the specified range, it will pass through the screening device and be sent out from the second exit. When the weight of the instrument batch exceeds the specified range, it proves that there is still water inside some instruments. At this time, the screening device rotates to change the movement trajectory of the instrument, so that multiple groups of instruments enter the first exit. A large number of instruments to be tested can be preliminarily screened. The batches of instruments that pass the waterproof test will pass through the second exit, and the batches of instruments that fail the waterproof test will pass through the first exit for manual inspection, which can save a lot of time and labor costs.

[0017] 2. The waterproof testing device for the production of this instrument is used by matching the limiting triangle plate and the limiting plate. When the transport frame moves to the top of the limiting triangle plate, the vertical surface of the limiting triangle plate will contact the limiting plate. As the transport frame continues to move to the right, the limiting triangle plate will squeeze the limiting plate, so that the limiting plate drives the rotating plate to rotate, so that the rotating plate drives the grid and the card ball to disengage from the card slot, and the grid contacts the inclined surface of the limiting triangle plate. At this time, the instrument inside the transport frame will slide out from the inside of the transport frame. When the transport frame moves to the left, the highest point of the limiting triangle plate will squeeze the grid, so that the grid drives the rotating plate to rotate, and finally the card ball enters the inside of the card slot, completing the closure of the bottom of the transport frame. The single mechanical operation makes the opening and closing of the bottom of the transport frame more stable and will not be affected by water.

[0018] 3. The waterproof test device for the production of this instrument can intercept impurities in the water flow entering the gutter by setting a filter net inside the gutter to prevent impurities from entering the water storage tank inside the test bench. The water in the water storage tank will be pumped into the water storage tank through a water pump and a water pipe for recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figures 1 to 7 As shown, the waterproof test device for instrument production in this embodiment includes a test platform 1, and a water storage tank is provided inside the test platform 1. The water storage tank is located inside the test platform 1. Through the opening connected to the outside, the user can inject clean water into the water storage tank. A set of second support plates 24 are installed at the front and rear ends of the test platform 1. Figure 6 As shown, the two groups of second support plates 24 are respectively located at the front and rear ends of the surface of the testing platform 1, and a transport frame 9 with a horizontal movement function is arranged between the two groups of second support plates 24. The transport frame 9 can move horizontally between the two groups of second support plates 24 within a certain range. A group of first support plates 4 are installed on the outer sides of the two groups of second support plates 24. The first support plates 4 have a certain height. A water storage tank 6 is installed between the upper parts of the two groups of first support plates 4. A water conduit 7 connected to the water storage tank is installed at the upper end of the water storage tank 6. The water conduit 7 pumps the water inside the water storage tank into the inside of the water storage tank 6 through a water pump. The water pump is installed inside the first support plate 4. A plurality of groups of nozzles 19 are installed at the lower end of the water storage tank 6. The lowest height of the plurality of groups of nozzles 19 is higher than the highest height of the transport frame 9. A water trough 25 is opened at the right side of the nozzle 19 on the surface of the testing platform 1. The water sprayed by the nozzle 19 will enter the inside of the water trough 25. The water trough 25 is connected to the water storage tank. The water discharged is recycled, a weight sensing device 5 is provided on the right side of the gutter 25 at the position on the surface of the test platform 1, and the batch of instruments sprayed with water will slide into the upper end of the weight sensing device 5 for weight determination, and a screening device 26 is installed on the right side of the weight sensing device 5 at the position on the surface of the test platform 1, a second outlet 21 is opened on the right side of the screening device 26, and a first outlet 3 is opened behind the screening device 26. When the weight of the batch of instruments is within the specified range, it will pass through the screening device 26 and be sent out from the second outlet 21. When the weight of the batch of instruments exceeds the specified range, it proves that there is still water inside some instruments. At this time, the screening device 26 rotates to change the moving trajectory of the instruments, so that multiple groups of instruments enter the first outlet 3, so that a large number of instruments to be tested can be preliminarily screened, and the batch of instruments that pass the waterproof test will pass through the second outlet 21, and the batch of instruments that fail the waterproof test will pass through the first outlet 3, and then manual inspection will be carried out, which can save a lot of time and labor costs.

[0031] Specifically, the screening device 26 includes a rotating column 2601 and a screening plate 2602. The surface of the test platform 1 is rotatably connected to the rotating column 2601. The lower end of the rotating column 2601 is connected to a driving motor installed inside the test platform 1. The surface of the rotating column 2601 is installed with a screening plate 2602. The length of the screening plate 2602 matches the width of the test platform 1. The rotating column 2601 is connected to the output end of the driving motor. The driving motor is electrically connected to the weight sensing device 5. The driving motor can drive the rotating column 2601 and the screening plate 2602 to rotate. When the screening plate 2602 does not rotate, the instrument will not be blocked and will be sent out from the second outlet 21. When the screening plate 2602 rotates, the second outlet 21 will be closed. At this time, the instrument will gradually enter the first outlet 3 at the rear end for delivery due to the blockage of the screening plate 2602.

[0032] Furthermore, a group of grooves 11 are provided on the inner end surfaces of the two groups of second support plates 24, and a threaded rod 13 is rotatably connected inside one group of grooves 11, and a guide rod 12 is installed inside the other group of grooves 11. The surface of the threaded rod 13 is connected to the transport frame 9 through a threaded moving block, and the surface of the guide rod 12 is connected to the transport frame 9 through a sliding moving block. A driving device 8 is installed at one end of the threaded rod 13, and the driving device 8 is fixedly installed on the surface of a group of second support plates 24. The threaded rod 13 is driven to rotate by the driving device 8, and the threaded rod 13 drives the moving plate to move along the length direction of the threaded rod 13, so that the transport frame 9 moves along the length direction of the threaded rod 13. The guide rod 12 can support and guide the movement of the transport frame 9, thereby enhancing the stability of the transport frame 9 when moving. The driving device 8 can select a common servo motor on the market.

[0033] Furthermore, a conveyor belt 2 is installed on the surface of the testing platform 1 at a position to the right of the weight sensing device 5. The batch of instruments passing through the weight sensing device 5 will enter the surface of the conveyor belt 2. When the screening device 26 does not rotate, the conveyor belt 2 will drive the instruments to the right side of the testing platform 1.

[0034] Furthermore, a water falling slope 22 is arranged at the position where the opening above the water falling trough 25 is connected to the inspection platform 1, and a plurality of sets of fans 23 are installed at the position on the surface of the inspection platform 1 to the right of the water falling slope 22. The lower end of the fan 23 is connected to the output end of the driving motor installed inside the inspection platform 1. The water falling slope 22 is an inclined plane inclined toward the water falling trough 25. Under the action of gravity, the water flow will enter the interior of the water falling trough 25 faster, and the remaining water inside the transport frame 9 will be dried by the fan 23.

[0035] Furthermore, a filter net 10 is installed inside the gutter 25. By setting the filter net 10 inside the gutter 25, impurities in the water flow entering the gutter 25 can be intercepted to prevent impurities from entering the water storage tank inside the testing platform 1. The water in the water storage tank will be pumped into the water storage tank 6 through the water pump and the water pipe 7 for recycling.

[0036] Furthermore, a limit triangle plate 27 is installed on the surface of the test platform 1 at a position on the left side of the weight sensing device 5, the inclined surface of the limit triangle plate 27 faces the right end of the test platform 1, and the vertical surface of the limit triangle plate 27 faces the left end of the test platform 1. Figure 6 As shown, it is installed between the fan 23 and the weight sensing device 5.

[0037] Furthermore, a rotating plate 17 is rotatably connected to the bottom of the inner wall at the left end of the transport frame 9, and a limiting plate 18 is installed at the lower end of the rotating plate 17 for matching with the limiting triangle plate 27. By matching the limiting triangle plate 27 and the limiting plate 18, when the transport frame 9 moves to the top of the limiting triangle plate 27, the vertical surface of the limiting triangle plate 27 will contact the limiting plate 18. As the transport frame 9 continues to move to the right, the limiting triangle plate 27 will squeeze the limiting plate 18, so that the limiting plate 18 drives the rotating plate 17 to rotate.

[0038] Furthermore, multiple groups of grids 14 are installed at the right end of the rotating plate 17, and a snap-in ball 16 is installed at the right end of the grid 14. Multiple groups of snap-in grooves 15 matching the snap-in balls 16 are opened at the bottom of the inner wall of the right end of the transport frame 9. The rotating plate 17 drives the grid 14 and the snap-in balls 16 to disengage from the snap-in grooves 15, and makes the grid 14 contact with the inclined surface of the limiting triangle plate 27. At this time, the instruments inside the transport frame 9 will slide out from the inside of the transport frame 9. When the transport frame 9 moves to the left, the highest point of the limiting triangle plate 27 will squeeze the grid 14, so that the grid 14 drives the rotating plate 17 to rotate, and finally makes the snap-in ball 16 enter the inside of the snap-in groove 15, completing the closure of the bottom of the transport frame 9. The single mechanical operation makes the opening and closing of the bottom of the transport frame 9 more stable and will not be affected by the water source.

[0039] Furthermore, a feed port 20 is provided at the left end of the testing platform 1 , and when the transport frame 9 is located near the feed port 20 , the user can put the instrument batch into the transport frame 9 .

[0040] The method of using this embodiment is as follows: by placing multiple groups of instruments in batches into the transport frame 9, the transport frame 9 is transported to the right side. When the transport frame is placed under the water storage tank 6, the water inside the water storage tank 6 is sprayed out through the nozzle 19 to spray the instruments inside the transport frame 9. The excess water falls through the grid 14 and enters the inside of the gutter 25. When the transport frame 9 enters above the fan 23, the remaining water inside the transport frame 9 is dried by the fan 23. When the transport frame 9 finally moves to above the limiting triangle plate 27, the vertical surface of the limiting triangle plate 27 will contact the limiting plate 18. As the transport frame 9 continues to move to the right, the limiting triangle plate 27 will squeeze the limiting plate 18. 8, so that the limiting plate 18 drives the rotating plate 17 to rotate, so that the rotating plate 17 drives the grid 14 and the receiving ball 16 to disengage from the receiving groove 15, and makes the grid 14 contact with the inclined surface of the limiting triangle plate 27. At this time, the instruments inside the transport frame 9 will slide out from the inside of the transport frame 9, and the instruments will enter the inclined surface of the limiting triangle plate 27 and fall onto the top of the weight sensing device 5. The weight of multiple groups of instruments will be determined by the weight sensing device 5. According to the determination results and the screening device 26, the batch of instruments without any problems will be sent out through the second outlet 21, and the batch of instruments with problems will enter the first outlet 3 under the obstruction of the screening device 26, and the second step of manual inspection will be carried out.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
