Description

Technical Field

[0001] The invention relates to the technical field of fuel injector mark detection equipment, and in particular to a fuel injector mark angle detection device. Background Art

[0002] The fuel injector itself is a normally closed valve (a normally closed valve means that when there is no input control signal, the valve is always in a closed state; a normally open valve means that when there is no input control signal, the valve is always in an open state). The opening and closing of the valve is controlled by a valve needle moving up and down. When the ECU issues a fuel injection command, its voltage signal will cause current to flow through the coil in the fuel injector, generating a magnetic field to lift the valve needle, allowing the valve to open so that the fuel can be sprayed out from the injection hole. The biggest advantage of injection fuel supply is that the fuel supply is very precisely controlled, allowing the engine to have the correct air-fuel ratio in any state, not only keeping the engine running smoothly, but also its exhaust gas can comply with environmental regulations.

[0003] With the widespread use of QR codes, QR codes are affixed to fuel injectors. Special equipment is usually used to interpret and verify the QR codes of fuel injectors. If the QR code is incorrect, subsequent operations will be affected. When scanning the fuel injectors in batches, it is usually done manually with a scanner. When picking up the fuel injectors, the staff not only needs to manually calibrate the position of the fuel injectors, but also needs to align the scanner with the QR code for scanning. This scanning method is not only time-consuming and labor-intensive, but also fails to improve efficiency, thereby wasting a lot of time for scanning, thereby reducing the production efficiency of the fuel injectors. Summary of the invention

[0004] The problem to be solved by the present invention is that manual code scanning of a fuel injector is inefficient, and the fuel injector needs to be manually calibrated before scanning the code.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a nozzle marking angle detection device, comprising a body, a motor is arranged on the top of the outer wall of the body, a rotating rod is installed on the output end of the motor through a coupling, a driving bevel gear is installed on the outer wall of the rotating rod through a coupling, a rotating disk is installed on one end of the rotating rod through a coupling, a connecting block is arranged on the outer wall of the rotating disk, a vibration rod is movably installed on the inner wall of the connecting block through a rotating shaft, a spring is arranged on the bottom of the outer wall of the vibration rod, a linkage block is installed on one side of the spring, a driven bevel gear is movably installed on one side of the driving bevel gear through a rotating shaft, a bottom bevel gear is movably installed on the bottom of the driven bevel gear through a rotating shaft, a chassis is installed on the bottom of the outer wall of the bottom bevel gear through a coupling, a linkage rod is installed on the outer wall of the chassis, a cavity is arranged on one end of the linkage rod, the diameter of the linkage rod cavity is slightly smaller than the diameter of the outer wall of the linkage block, a material box is movably installed on one end of the vibration rod through a rotating shaft, a cavity is arranged on the inner wall of the material trough, and the outer wall of the material trough is inclined.

[0006] Preferably, a bottom plate is provided at the bottom of the outer wall of the material discharge box, a force spring is installed on the outer wall of the bottom plate, a mounting rod is provided on one side of the inner wall of the body, a barcode scanner is installed at one end of the mounting rod, and a side plate is provided on the outer wall of the barcode scanner.

[0007] Preferably, a feeding bin is provided on one side of the top of the outer wall of the body, a conveyor belt is installed on the front side of the feeding bin, a feeding port is provided on one side of the conveyor belt, and a discharge pipe is installed at the bottom of the feeding port.

[0008] Preferably, a material receiving bin is provided at the bottom of the barcode scanner, a feed pipe is installed at the bottom of the material receiving bin, a material collection bin is installed at the bottom of the feed pipe, and a material taking door is provided on one side of the material collection bin.

[0009] Preferably, the vibration rod is movably mounted on the outer wall of the turntable via a connecting block, and the vibration rod is distributed in a circular shape on the outer wall of the turntable.

[0010] Preferably, one end of the force spring is connected to the outer wall of the bottom plate, and the other end of the force spring is connected to the outer wall of the material box.

[0011] Preferably, the linkage block is cylindrical and is installed on one side of the bottom of the outer wall of the vibration rod.

[0012] Preferably, the tooth grooves of the driving bevel gear, the driven bevel gear and the bottom bevel gear are meshed with each other, and the bottom of the outer wall of the bottom bevel gear is connected to the chassis through a coupling.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] (1) When the fuel injector falls to the inner wall of the material box, due to its "L" shape and the QR code at the shorter end, it may get stuck on the outer wall of the material trough. At this time, the linkage rod and the turntable are in a forward and reverse state. Through the interaction between the linkage block and the linkage rod, the vibration rod presents a vibrating motion form. This vibration can not only help the fuel injector to smoothly enter the inner wall of the material trough, but also keep the QR code facing up and fall in. In this way, the automatic calibration of the fuel injector is realized, which greatly facilitates the subsequent code scanning work. Since the fuel injector has realized automatic calibration, the barcode scanner can directly scan it without manual calibration. This design not only simplifies the code scanning process, but also improves the accuracy and efficiency of code scanning. At the same time, since the entire code scanning process is automatically controlled, the interference of human factors is greatly reduced, and the stability and reliability of production are improved.

[0015] (2) The turntable drives the material box to rotate so that the fuel injector can automatically adjust to the position directly below the barcode scanner, thereby realizing automatic barcode scanning. This design not only simplifies the preparation work before barcode scanning, but also improves the accuracy and efficiency of barcode scanning. Compared with the traditional manual barcode scanning method, the device can significantly reduce the time and labor cost required for barcode scanning and improve production efficiency. The turntable transmission method does not require manual picking up of the fuel injector, but only requires the fuel injector to be placed in the feed bin. After the barcode scanning is completed, the fuel injector can also be automatically collected, thereby realizing efficient and automatic barcode scanning of the fuel injector and greatly improving production efficiency.

[0039] In this embodiment, the linkage block 12 is cylindrical and is installed on one side of the bottom of the outer wall of the vibration rod 6. When the linkage block 12 rotates, it will just contact the linkage rod 17. Since the linkage rod 17 is reversed and the cavity diameter of the linkage rod 17 is slightly smaller than the diameter of the outer wall of the linkage block 12.

[0040] In this embodiment, the tooth grooves of the active bevel gear 13, the driven bevel gear 14 and the bottom bevel gear 15 are meshed with each other, and the bottom of the outer wall of the bottom bevel gear 15 is connected to the chassis 16 through a coupling. When the active bevel gear 13 rotates, it will drive the driven bevel gear 14 to rotate, and when the driven bevel gear 14 rotates, it will drive the bottom bevel gear 15 to rotate, and the bottom bevel gear 15 will drive the chassis 16 to rotate through the coupling.

[0041] The working principle and use process of the present invention: First, when using the present invention, the user can realize the automation of the code scanning of the fuel injector to the maximum extent. The specific use method is that the user needs to first put the fuel injector into the feed bin 21 set at the top of the outer wall of the body 1. After the fuel injector is put into the feed bin 21, it will roll onto the conveyor belt 22, and be transported to the feed port 23 by the conveyor belt 22, and fall into the inside of the discharge pipe 24 from the feed port 23, and then the fuel injector will fall to the inner wall of the discharge box 8;

[0042] Specifically, when using the device, the user needs to start the motor 2 first. After the motor 2 is started, its output end will drive the rotating rod 3 to rotate synchronously through the coupling, and the rotating rod 3 will drive the turntable 4 to rotate synchronously when rotating, and the turntable 4 will drive the vibration rod 6 to rotate synchronously when rotating, and the vibration rod 6 will drive the unloading box 8 to rotate when rotating, and the rotating rod 3 will synchronously drive the active bevel gear 13 to rotate when rotating, and the active bevel gear 13 will drive the driven bevel gear 14 to rotate when rotating, and the driven bevel gear 14 will drive the bottom bevel gear 15 to rotate when rotating, and the bottom bevel gear 15 will drive the chassis 16 to rotate through the coupling, and the linkage rod 17 provided on the outer wall of the chassis 16 will rotate synchronously, and at this time, the linkage rod 17 is reversed, while the turntable 4 is forward;

[0043] Secondly, when the fuel injection nozzle falls to the inner wall of the material box 8, see Fig.14As shown, due to its "L" shape and the QR code at the shorter end of the "L" shape, the fuel injector may be stuck on the outer wall of the feed chute 11 at this time. At this time, the linkage rod 17 and the turntable 4 are in a forward and reverse state. When the turntable 4 is rotating forward, the linkage block 12 at the bottom of the outer wall of the vibration rod 6 is also rotating. When the linkage block 12 rotates, it will just contact the linkage rod 17. Since the linkage rod 17 is reversed and the cavity diameter of the linkage rod 17 is slightly smaller than the diameter of the outer wall of the linkage block 12, then the linkage rod 17 will give the linkage block 12 an extrusion force at this time. After being subjected to the force, the linkage block 12 will drive the vibration rod 6 to rotate slightly. When the vibration rod 6 rotates slightly, the spring 7 will make the vibration rod 6 present a vibrating motion form. When the vibration rod 6 vibrates, it will drive the feed box 8 to vibrate. When the feed box 8 vibrates, it will make the fuel injector enter the inner wall of the feed chute 11. Since the cavity diameter of the inner wall of the feed chute 11 is small, the fuel injector will always keep the QR code facing up and fall in.

[0044] Finally, the feed box 8 is rotated by the rotation of the turntable 4. When the feed box 8 rotates to the bottom of the barcode scanner 19, the barcode scanner 19 will scan the oil nozzle on the inner wall of the feed trough 11. At the same time, the feed box 8 will touch the side plate 20 provided on the outer wall of the barcode scanner 19 due to the continuous rotation. The side plate 20 will drive the feed box 8 to rotate. When the feed box 8 rotates, the oil nozzle on the inner wall of the feed trough 11 will fall to the receiving bin 25 and enter the feed pipe 26 through the receiving bin 25. , and then falls into the collecting bin 27 through the feeding pipe 26 for collection. When the discharge box 8 rotates to a certain position, it will be separated from the side plate 20. At this time, the force spring 10 will drive the discharge box 8 to reset, and then the discharge box 8 continues to rotate to the bottom of the discharge pipe 24. The rotation method allows the fuel injector to continuously feed and discharge, and can adjust the position by itself for scanning, eliminating the trouble of manual scanning, and the fuel injector can be automatically collected.
