Technical Field

[0001] The invention relates to the technical field of passive film detection, and in particular to a portable rapid detector for passive film of metal parts. Background Art

[0002] The passivation film of metal parts is a coating formed on the metal surface by anodizing. The detection of metal passivation film includes potassium ferrocyanide method, copper sulfate method, salt spray test method, ferric chloride pitting corrosion method, etc. The potassium ferrocyanide method uses iron ions to react chemically with potassium ferrocyanide in the test solution under acidic conditions to generate blue Teng's blue precipitate; the copper sulfate method detects the passivation film by detecting that copper sulfate in the liquid reacts with iron ions; the salt spray test method is to immerse the surface of the metal part to be tested in a salt water containing (5±0.5)% sodium chloride and a pH value of 6.5-7.2 in a specific test box, and observe its surface corrosion state after a certain period of time; the ferric chloride pitting corrosion method is to immerse the passivated product in a ferric chloride solution with a concentration of 6% for detection; the metal part passivation film detection device in the prior art usually can only use one method to detect the metal part passivation film, and it is impossible to collect and reuse the waste liquid after the reaction. At the same time, the addition of reagents needs to be done manually, and the removal of metal blocks is done manually, which is dangerous. Summary of the invention

[0004] The rotation of the liquid feeding motor drives the liquid feeding shaft to rotate, and the rotation of the blades on the liquid feeding shaft generates suction, so that the upper top plate moves upward along the liquid feeding tank, and the upper top spring is compressed. At this time, the upper top plate no longer blocks the top of the liquid feeding pipe, and the detection liquid in the liquid feeding tank is drawn into the liquid feeding pipe. Then the detection liquid enters the liquid feeding shell through the liquid inlet groove and the liquid inlet, and is transported to the liquid outlet pipe through the blades on the liquid feeding shaft. The diameter of the liquid feeding shaft blade gradually decreases near the liquid outlet pipe, so that the water flow out of the liquid outlet pipe is smoother.

[0005] Furthermore, the box device includes four wheel seats rotatably mounted on the bottom of the box, movable wheels are rotatably mounted on the wheel seats, a protective shell is fixedly mounted on the box, a handle is fixedly mounted on the protective shell, and four detection cylinders are fixedly mounted on the box.

[0006] Furthermore, a closing mechanism is provided on the box body, and the closing mechanism includes a closing motor fixedly mounted on the box body, three arc seats fixedly mounted on the box body, an arc groove is provided on the arc seat, a motor rotating rod is fixedly mounted on the motor shaft of the closing motor, a connecting rotating shaft is rotatably mounted on the arc seat, the connecting rotating shaft is rotatably mounted with four detection cylinders, four cylinder covers are fixedly mounted on the connecting rotating shaft, a guide column is fixedly mounted on the cylinder cover, the guide column is fixedly mounted with the motor rotating rod, a guide sleeve is fixedly mounted on the guide column, and the guide sleeve slides in the arc groove of the arc seat.

[0007] The entire detector can be lifted by the handle, or moved by the moving wheels and wheel seat. When the reaction liquid is injected into the detection tube, the cover closing motor rotates to drive the motor rotating rod to rotate, thereby driving the guide column and the tube cover to rotate, thereby driving the guide sleeve to slide along the arc groove of the arc seat, and driving the four tube covers to move synchronously through the connecting shaft, so that the tube cover is covered on the corresponding detection tube.

[0008] Furthermore, the clamping device includes a lifting electric cylinder fixedly installed on the upper frame, a sliding sleeve fixedly installed on the upper frame, a lifting column slidably installed in the sliding sleeve, a lifting seat fixedly installed on the top of the lifting electric cylinder, the lifting seat and the lifting column are fixedly installed, a side sliding column fixedly installed on the lifting seat, two clamping seats slidably installed on the side sliding column, clamping claws fixedly installed on the clamping seat, a sliding column spring is arranged between the clamping seat and the lifting seat, two side guide blocks are arranged below the clamping seat, and a slope is arranged on the side guide blocks.

[0009] Furthermore, a push-open electric cylinder is fixedly installed on the lifting seat, a push-down slope block is fixedly installed on the top of the push-open electric cylinder, a slope surface is arranged on the lower surface of the push-down slope block, and a push-open slope block is fixedly installed on the clamping seat, and a slope surface is arranged on the push-open slope block.

[0010] When in use, push the clamping claw outward to place the metal block between the side guide blocks, and use the sliding column spring to clamp the metal block. Then the lifting electric cylinder extends to drive the lifting seat to descend, and the lifting column descends along the sliding sleeve to place the metal block in the four slope guide blocks. At this time, the top opening electric cylinder extends to drive the push-down slope block to descend, thereby pushing the push-open slope block and the clamping seat to slide outward along the side sliding column. The sliding column spring is compressed, causing the clamping claw to release the metal block and keep the metal block in the slope guide block. Then the lifting electric cylinder contracts to drive the lifting seat back to the top.

[0011] When the metal block completes the reaction, the lifting electric cylinder extends and drives the lifting seat down. When the slope surface under the clamp contacts the metal block, the metal block will push the clamp and the clamp seat outward along the side sliding column. The sliding column spring is compressed, so that the clamp is located on both sides of the metal block and clamps the metal block through the clamp. The slope surface of the slope guide block is convenient for the metal block to be placed in. Then the lifting electric cylinder contracts and drives the lifting seat to rise. Then the pickup tray is manually placed under the metal block. The top opening electric cylinder extends and drives the push-down slope block to descend, so that the clamp seat slides outward along the side sliding column. The sliding column spring is compressed, and the metal block falls into the tray. The metal block is manually observed to draw the detection conclusion.

[0012] Furthermore, the recovery device includes a disassembly recovery plate which is detachably fixed on the box body by connecting bolts, a side panel is fixedly installed on the disassembly recovery plate, four recovery tanks are arranged in the side panel, the recovery tank is located below the detection cylinder, a liquid spray pipe is fixedly installed on the liquid outlet pipe, the liquid spray pipe is fixedly installed with the detection cylinder, a flow outlet is arranged at the bottom of the detection cylinder, the bottom of the inner wall of the detection cylinder is a conical surface, a discharge pipe is arranged in the recovery tank, and a ball valve is rotatably installed on the discharge pipe.

When the closing block blocks the flow outlet, the compression spring is in a normal state and the clamping rod is located in the clamping slot. When the closing block is required not to block the flow outlet, the pull rod is pulled out and rotated one hundred and eighty degrees, the compression spring is in a compressed state, and the clamping rod is located in the upper clamping block.

[0014] Furthermore, four slope guide blocks are fixedly installed in the detection cylinder, the inner sides of the slope guide blocks are provided with slope surfaces, and the metal blocks are placed in the slope guide blocks.

[0015] When the metal block is placed in the slope guide block, the detection liquid enters the detection cylinder through the liquid outlet pipe and the liquid spray pipe. At this time, the outflow port is blocked by the closing block, and the detection liquid soaks the metal block and reacts. When the detection is completed, the pull rod is pulled outward, and the card rod leaves the slot, so that the closing block leaves the outflow port, the compression spring is compressed, and then the pull rod is rotated 180 degrees, and the pull rod is stuck in the upper block. At this time, the compression spring cannot rebound, and the liquid in the detection cylinder flows into the recovery tank through the outflow port for collection. When the liquid in the detection cylinder is emptied, the pull rod is pulled outward and rotated 180 degrees, the pull rod is released, the card rod enters the slot, the closing block closes the outflow port again, and then the metal block is taken out.

[0016] When the detected liquid in the recovery tank reaches a certain amount, the ball valve can be turned to discharge the liquid in the recovery tank from the discharge pipe.

[0017] The liquid delivery tank and the recovery tank can be disassembled for cleaning. The liquid delivery plate and the recovery plate can be removed by unscrewing the connecting bolts. Then the recovery tank can be taken out from the side plate, and the liquid delivery tank can also be taken out from the positioning piece.

[0018] Compared with the prior art, the present invention has the following advantages: (1) after the clamping device places the metal block into the detection cylinder, the injection device provided in the present invention automatically extracts the reagent in the liquid delivery tank and smoothly delivers it into the detection cylinder. The reagent reacts with the metal block in the detection cylinder. After the reaction is completed, the metal block is taken out by the clamping device, and the reagent is automatically delivered, thereby avoiding direct contact between the operator and the reagent, thereby improving safety; (2) when the metal block provided in the present invention is detected in the detection cylinder, the flow outlet between the detection cylinder and the recovery tank is closed by the closing block. After the reaction of the metal block in the detection cylinder is completed, the flow outlet can be opened, and the used reagent can flow into the recovery tank for collection, which is convenient for subsequent reuse. When the flow outlet is opened, the clamping rod is clamped into the upper clamping block. When the flow outlet is closed, the clamping rod is located in the clamping groove. The invention is convenient for operation; (3) the four recovery tanks provided by the invention can be respectively used to place four detection reagents, namely potassium ferrocyanide, copper sulfate, 5% sodium chloride and ferric chloride, so that the passivation film of the metal block made by the same process can be detected by different detection methods; the same reagent can also be placed in the four recovery tanks, and the passivation film of the metal block made by different processes can be detected by the same reagent, and the detection effect is good; (4) the cover closing mechanism provided by the invention can automatically close the four detection cylinders at the same time after the metal block is placed in, so as to prevent the invasion of external pollutants and affect the detection effect of the metal block. At the same time, the liquid feeding tank and the recovery tank are easy to disassemble, and the liquid in the recovery tank can be discharged after the ball valve is opened after a certain amount of liquid is collected. At the same time, the whole detector can be lifted and moved by the handle, and can also be pushed by four moving wheels, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The rotation of the liquid feeding motor 305 drives the liquid feeding shaft 308 to rotate, and the rotation of the blades on the liquid feeding shaft 308 generates suction, so that the upper top plate 309 moves upward along the liquid feeding tank 302, and the upper top spring 310 is compressed. At this time, the upper top plate 309 no longer blocks the top of the liquid feeding pipe 311, and the detection liquid in the liquid feeding tank 302 is drawn into the liquid feeding pipe 311.

[0039] The entire detector can be lifted by the handle 107, or moved by the moving wheel 103 and the wheel seat 102. When the reaction liquid is injected into the detection tube 108, the cover closing motor 109 rotates to drive the motor rotating rod 110 to rotate, thereby driving the guide column 111 and the tube cover 112 to rotate, thereby driving the guide sleeve 113 to slide along the arc groove of the arc seat 114, and driving the four tube covers 112 to move synchronously through the connecting shaft 115, so that the tube cover 112 covers the corresponding detection tube 108.

[0041] like Figure 8-Figure 10As shown, a push-open electric cylinder 205 is fixedly installed on the lifting seat 204, a push-down ramp block 206 is fixedly installed on the top of the push-open electric cylinder 205, and a slope is provided on the lower surface of the push-down ramp block 206, and a push-open ramp block 210 is fixedly installed on the clamping seat 209, and a slope is provided on the push-open ramp block 210.

[0042] When in use, the clamping claw 211 is pushed outward to place the metal block 411 between the side guide blocks 212, and the clamping claw 211 clamps the metal block 411 through the sliding column spring 208, and then the lifting cylinder 201 extends to drive the lifting seat 204 to descend, and the lifting column 203 descends along the sliding sleeve 202 to place the metal block 411 in the four slope guide blocks 415.

[0043] When the metal block 411 completes its reaction, the lifting electric cylinder 201 extends and drives the lifting seat 204 to descend. When the slope surface below the clamping claw 211 contacts the metal block 411, the metal block 411 will push the clamping claw 211 and the clamping seat 209 outward along the side sliding column 207, and the sliding column spring 208 is compressed, so that the clamping claw 211 is located on both sides of the metal block 411, and the metal block 411 is clamped by the clamping claw 211. The slope surface of the slope guide block 415 is convenient for the metal block 411 to be placed in. Then the lifting electric cylinder 201 contracts and drives the lifting seat 204 to rise. Then the picking tray is manually placed under the metal block 411, and the top opening electric cylinder 205 extends and drives the push-down slope block 206 to descend, so that the clamping seat 209 slides outward along the side sliding column 207. The sliding column spring 208 is compressed, and the metal block 411 falls into the tray. The metal block 411 is manually observed to draw a detection conclusion.

[0044] like Figure 11-Figure 14 As shown, the recovery device includes a disassembly recovery plate 401 which is detachably fixed on the box body 101 by connecting bolts 104, a side plate 403 is fixedly installed on the disassembly recovery plate 401, four recovery tanks 402 are arranged in the side plate 403, the recovery tank 402 is located below the detection cylinder 108, a liquid spraying pipe 412 is fixedly installed on the liquid outlet pipe 307, the liquid spraying pipe 412 is fixedly installed with the detection cylinder 108, a flow outlet 416 is arranged at the bottom of the detection cylinder 108, the bottom of the inner wall of the detection cylinder 108 is a conical surface, a discharge pipe 413 is arranged in the recovery tank 402, and a ball valve 414 is rotatably installed on the discharge pipe 413.

When the closing block 409 blocks the flow outlet 416, the compression spring 410 is in a normal state, and the clamping rod 406 is located in the clamping groove 407. When the closing block 409 is required not to block the flow outlet 416, the pull rod 405 is pulled out and rotated 180 degrees, the compression spring 410 is in a compressed state, and the clamping rod 406 is located in the upper clamping block 404.

[0046] like Figure 11-Figure 14 As shown, four slope guide blocks 415 are fixedly installed in the detection cylinder 108 , the inner sides of the slope guide blocks 415 are provided with slope surfaces, and the metal blocks 411 are placed in the slope guide blocks 415 .

[0047] When the metal block 411 is placed in the slope guide block 415, the detection liquid enters the detection cylinder 108 through the liquid outlet pipe 307 and the liquid spray pipe 412. At this time, the flow outlet 416 is blocked by the closing block 409. The detection liquid soaks the metal block 411 and reacts. When the detection is completed, the pull rod 405 is pulled outward, the clamping rod 406 leaves the clamping groove 407, so that the closing block 409 leaves the flow outlet 416, the compression spring 410 is compressed, and then the pull rod 405 is rotated. The pull rod 405 is turned 180 degrees and inserted into the upper clamping block 404. At this time, the compression spring 410 cannot rebound, and the liquid in the detection cylinder 108 flows into the recovery tank 402 through the outflow port 416 for collection. When the liquid in the detection cylinder 108 is emptied, the pull rod 405 is pulled outward and rotated 180 degrees to release the pull rod 405. The clamping rod 406 enters the clamping groove 407, and the closing block 409 closes the outflow port 416 again. Then, the metal block 411 is taken out by the clamping device.

[0048] When the amount of the detected liquid in the recovery tank 402 reaches a certain amount, the ball valve 414 can be rotated to discharge the liquid in the recovery tank 402 from the discharge pipe 413 .

[0049] The liquid delivery tank 302 and the recovery tank 402 can be disassembled and cleaned.

There are two detection methods in total. Four detection reagents, potassium ferrocyanide, copper sulfate, 5% sodium chloride and ferric chloride, can be placed in four recovery tanks 402 respectively, and the passivation films of metal blocks 411 made by the same process can be detected by different detection methods; or the same reagent can be placed in four recovery tanks 402, and the passivation films of metal blocks 411 made by different processes can be detected by the same reagent.

[0051] When in use, the clamping claw 211 is pushed outward to place the metal block 411 between the side guide blocks 212, and the clamping claw 211 clamps the metal block 411 through the sliding column spring 208, and then the lifting cylinder 201 extends to drive the lifting seat 204 to descend, and the lifting column 203 descends along the sliding sleeve 202 to place the metal block 411 in the four slope guide blocks 415. At this time, the top cylinder 205 extends to drive the push-down slope block 206 to descend, thereby pushing the push-open slope block 210 and the clamping seat 209 to slide outward along the side sliding column 207, and the sliding column spring 208 is compressed, so that the clamping claw 211 releases the metal block 411 and keeps the metal block 411 in the slope guide block 415, and then the lifting cylinder 201 contracts to drive the lifting seat 204 back to the top. The liquid delivery shaft 308 is driven to rotate by the liquid delivery motor 305, and the rotation of the liquid delivery shaft 308 generates suction, so that the upper top plate 309 moves upward along the liquid delivery tank 302, and the upper top spring 310 is compressed. At this time, the upper top plate 309 no longer blocks the top of the liquid delivery pipe 311, and the detection liquid in the liquid delivery tank 302 is drawn into the liquid delivery pipe 311, enters the liquid delivery shell 306 through the liquid inlet groove 312 and the liquid inlet port 313, and the liquid is delivered to the liquid outlet pipe 307 through the liquid delivery shaft 308. The diameter of the blade of the liquid delivery shaft 308 gradually decreases near the liquid outlet pipe 307, so that the water flow at the liquid outlet pipe 307 is smoother.When the metal block 411 is placed in the slope guide block 415, the detection liquid enters the detection tube 108 through the liquid outlet pipe 307 and the liquid spray pipe 412. When the reaction liquid is injected into the detection tube 108, the cover closing motor 109 rotates to drive the motor rotating rod 110 to rotate, thereby driving the guide column 111 and the tube cover 112 to rotate, thereby driving the guide sleeve 113 to slide along the arc groove of the arc seat 114, and driving the four tube covers 112 to move synchronously through the connecting shaft 115, so that the tube cover 112 covers the corresponding detection tube 108. At this time, The outflow port 416 is blocked by the closing block 409, and the detection liquid soaks the metal block 411 and reacts. When the detection is completed, the pull rod 405 is pulled outward, and the clamping rod 406 leaves the clamping groove 407, so that the closing block 409 leaves the outflow port 416, and the compression spring 410 is compressed. Then the pull rod 405 is rotated 180 degrees, and the pull rod 405 is clamped into the upper clamping block 404. At this time, the compression spring 410 cannot rebound, and the liquid in the detection cylinder 108 flows into the recovery tank 402 through the outflow port 416 for collection. When the liquid in the detection cylinder 108 is emptied, the pull rod 405 is pulled outward and rotated 180 degrees to release the pull rod 405, the clamping rod 406 enters the clamping groove 407, and the closing block 409 closes the outflow port 416 again. Then the lifting cylinder 201 extends to drive the lifting seat 204 to descend. When the slope below the clamping jaw 211 contacts the metal block 411, the metal block 411 pushes the clamping jaw 211 and the clamping seat 209 outward along the side sliding column 207, and the sliding column spring 208 is compressed, so that the clamping jaw 211 is located on the metal block 411. The metal block 411 is clamped on both sides by the clamping claws 211. The slope of the slope guide block 415 is convenient for the metal block 411 to be placed in. Then the lifting cylinder 201 contracts to drive the lifting seat 204 to rise. Then the pickup tray is manually placed under the metal block 411, and the top cylinder 205 extends to drive the push-down slope block 206 to descend, so that the clamping seat 209 slides outward along the side sliding column 207, the sliding column spring 208 is compressed, and the metal block 411 falls into the tray. The metal block 411 is manually observed to draw a detection conclusion.
