Description

Technical Field

[0001] This invention relates to the field of pump core assembly line technology, and in particular to a device for preventing leakage of small parts in an automated assembly line. Background Technology

[0002] As the core component of an oil pump, the pump core is composed of precision components such as stator, rotor, blades, and pressure side plate. Its design and manufacturing level directly determines the oil pump's oil suction efficiency, pressure stability, and service life, playing a key role in the engine lubrication and cooling system and fuel supply system.

[0003] In existing technologies, small parts on assembly lines are prone to being missed due to their small size, light weight, and tendency to jam. Currently, this is mainly done manually, with replacements only when missed. However, due to the small size of these parts, manual inspection is easily missed due to inattention or visual fatigue, which can affect subsequent processing. Therefore, there is an urgent need for an improved device to prevent the missed feeding of small parts on automated assembly lines. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for preventing the leakage of small parts in automated assembly lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for preventing leakage of small parts in an automated assembly line, comprising a transverse adjustment mechanism, a longitudinal adjustment mechanism, and an auxiliary adjustment mechanism. The transverse adjustment mechanism includes a transverse arc frame with a groove on its outer wall, and an arc-shaped toothed plate fixedly disposed within the groove. The longitudinal adjustment mechanism includes a frame slidably disposed on the outer wall of the transverse arc frame. A drive shaft and a limit wheel are rotatably connected to the upper and lower ends of the frame, respectively. A drive gear is fixedly connected to the outer wall of the drive shaft, and the drive gear meshes with the arc-shaped toothed plate. A longitudinal arc frame is fixedly connected to the lower end face of the frame. The auxiliary adjustment mechanism includes a slider slidably connected to the longitudinal arc frame, and a positioning screw is threadedly connected to one side of the slider. The positioning screw is pressed against the outer wall of the longitudinal arc frame. A mounting bracket is fixedly connected to the lower end of the slider. A driven shaft is rotatably connected to the mounting bracket near the lower end. A driven gear is fixedly connected to the outer wall of the driven shaft. A mounting plate is fixedly connected to the lower end of the driven gear. A mounting box is fixedly connected to the lower end of the mounting plate. A monitoring tube is fixedly connected to one side of the lower end face of the mounting box. A main control module, a comparison module, a power supply module, and an image acquisition module are respectively arranged inside the mounting box. The acquisition lens of the image acquisition module is set inside the monitoring tube. An alarm module is fixedly connected to the upper end of the frame. A display module is fixedly connected to the side wall of the frame. The display module, alarm module, comparison module, and image acquisition module are all electrically connected to the main control module.

[0006] Furthermore, both ends of the transverse arc frame are fixedly connected to fixing plates, and the fixing plates are provided with mounting grooves for installing bolts.

[0007] By bolting through the mounting slots on the fixing plate, a transverse arc frame can be erected on the assembly line for monitoring small parts.

[0008] Furthermore, a motor is fixedly connected to the outer wall of the frame, and the output end of the motor is fixedly connected to one end of the drive shaft.

[0009] By driving the drive shaft to rotate via a motor, the drive gear can be rotated, thereby controlling the movement of the frame relative to the transverse arc frame.

[0010] Furthermore, the drive gear is rotatably disposed within the groove, and the limiting wheel presses against the lower arc surface of the transverse arc frame.

[0011] The limit wheels, together with the drive gears, are distributed at the upper and lower ends of the transverse arc frame, making it easy to slide the frame onto the transverse arc frame.

[0012] Further: A marking line one is fixedly installed on the outer wall of the transverse arc frame, a marking line two is fixedly installed on the outer wall of the longitudinal arc frame, a viewing window one is fixedly installed on the outer wall of the frame, the viewing window one is oriented towards the marking line one, and a viewing window two is fixedly installed on the outer wall of the slider, the viewing window two is oriented towards the marking line two.

[0013] By observing line one through window one, one can know the tilt angle of the longitudinal adjustment mechanism on the lateral adjustment mechanism. By observing line two through window two, one can know the tilt angle of the auxiliary adjustment mechanism on the longitudinal adjustment mechanism.

[0014] Furthermore: an adjusting shaft is rotatably connected to the mounting bracket, an adjusting gear is fixedly connected to the outer wall of the adjusting shaft, the adjusting gear meshes with the driven gear, a knob is fixedly connected to one end of the adjusting shaft, and multiple positioning grooves are provided on the outer wall of the knob.

[0015] The adjustment shaft is rotated by turning the knob, which in turn drives the adjustment gear to rotate, which in turn drives the driven gear to rotate, thereby adjusting the tilt angle of the mounting plate.

[0016] Furthermore: multiple positioning slots are evenly distributed on the outer wall of the knob, and a connecting ear is fixedly connected to the side wall of the mounting bracket. A positioning rod is slidably connected to the connecting ear, and the positioning rod is engaged with the positioning slot.

[0017] By fitting the positioning rod into the positioning groove, the knob can be fixed after each rotation to a specified angle, thereby locking the driven gear after rotation adjustment.

[0018] Furthermore, a spring is fixedly connected between the end cap and the connecting lug of the positioning rod, and the spring is movably sleeved on the outer end of the positioning rod.

[0019] The spring is used to pull the end cap of the positioning rod, so that the positioning rod can always be fitted into the positioning groove without being pulled.

[0020] The present invention has the following beneficial effects:

[0021] 1. Compared with existing technologies, this device, through the coordinated operation of a lateral adjustment mechanism, a longitudinal adjustment mechanism, and an auxiliary adjustment mechanism, enables the image acquisition module to move relative to the lateral arc frame via the meshing relationship between the drive gear and the arc-shaped toothed plate. Simultaneously, the sliding slider on the longitudinal arc frame allows the image acquisition module to move relative to the longitudinal arc frame, thereby adjusting the monitoring angle of the image acquisition module in multiple directions. This allows for better image acquisition of small parts on the assembly line, resulting in higher accuracy and greater ease of use compared to manual inspection.

[0022] 2. Compared with the existing technology, the mounting bracket, knob, adjusting shaft, adjusting gear, driven shaft and driven gear structure of this device can further drive the adjusting shaft to rotate through the knob, which in turn drives the adjusting gear to rotate, thereby driving the driven gear to rotate, and finally realize the compensation angle adjustment of the image acquisition module. This avoids the limitation of the monitoring range caused by the size of the longitudinal arc frame. In addition, with the positioning groove and positioning rod on the surface of the knob, it can be fixed after the knob is rotated to a specified angle, so as to achieve the purpose of locking the angle.

[0023] 3. Compared with the prior art, this device sets a first mark on the surface of the transverse arc frame and a second mark on the surface of the longitudinal arc frame. Combined with a first viewing window on the frame and a second viewing window on the slider, the tilt angle can be determined according to the mark indication during the adjustment process, making it easier to adjust the device to the specified angle and easier to operate.

It is made of DC12V sound and light alarm, power module 6 is made of 12V / 2A switching power supply module, and display module 26 is made of TFT LCD screen.

[0036] Both ends of the transverse arc frame 11 are fixedly connected to a fixing plate 15, and the fixing plate 15 is provided with a mounting groove 16 for mounting bolts. By passing the bolts through the mounting groove 16 on the fixing plate 15, the transverse arc frame 11 can be erected on the assembly line for monitoring small parts.

[0037] A motor 28 is fixedly connected to the outer wall of the frame 21. The output end of the motor 28 is fixedly connected to one end of the drive shaft 22. The motor 28 drives the drive shaft 22 to rotate, which in turn drives the drive gear 23 to rotate, thereby controlling the frame 21 to move relative to the transverse arc frame 11.

[0038] The drive gear 23 is rotatably set in the groove 12, and the limiting wheel 24 is pressed against the lower arc surface of the transverse arc frame 11. The limiting wheel 24 and the drive gear 23 are distributed at the upper and lower ends of the transverse arc frame 11, which facilitates the sliding connection of the frame 21 to the transverse arc frame 11.

[0039] A first mark 14 is fixedly installed on the outer wall of the transverse arc frame 11, a second mark 210 is fixedly installed on the outer wall of the longitudinal arc frame 29, a first viewing window 25 is fixedly installed on the outer wall of the frame 21, the first viewing window 25 is oriented toward the first mark 14, and a second viewing window 316 is fixedly installed on the outer wall of the slider 31, the second viewing window 316 is oriented toward the second mark 210.

By observing the second mark 210 through the second viewing window 316, the tilt angle of the auxiliary adjustment mechanism 3 on the longitudinal adjustment mechanism 2 can be known.

[0040] An adjusting shaft 33 is rotatably connected to the mounting bracket 32. An adjusting gear 34 is fixedly connected to the outer wall of the adjusting shaft 33. The adjusting gear 34 meshes with the driven gear 36. A knob 310 is fixedly connected to one end of the adjusting shaft 33. Multiple positioning grooves 311 are provided on the outer wall of the knob 310. The knob 310 drives the adjusting shaft 33 to rotate, which in turn drives the adjusting gear 34 to rotate, which in turn drives the driven gear 36 to rotate, thereby adjusting the tilt angle of the mounting plate 37.

[0041] Multiple positioning slots 311 are evenly distributed on the outer wall of the knob 310. A connecting ear 312 is fixedly connected to the side wall of the mounting bracket 32. A positioning rod 313 is slidably connected to the connecting ear 312. The positioning rod 313 is engaged with the positioning slot 311. By fitting the positioning rod 313 into the positioning slot 311, the knob 310 can be fixed after rotating a specified angle each time, thereby locking the driven gear 36 after rotation adjustment.

[0042] A spring 314 is fixedly connected between the end cap of the positioning rod 313 and the connecting ear 312. The spring 314 is movably sleeved on the outer end of the positioning rod 313. The spring 314 is used to pull the end cap of the positioning rod 313 so that the positioning rod 313 can always be sleeved in the positioning groove 311 without being pulled.

[0043] Working principle: The transverse arc frame 11 is fixed to the assembly line by bolts through the fixing plate 15 and mounting groove 16 of the transverse adjustment mechanism 1. The power module 6 supplies power to the entire device. Then, the motor 28 is started to drive the drive shaft 22 to rotate, which in turn drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the arc-shaped toothed plate 13 in the groove 12 of the transverse arc frame 11, the frame 21 moves along the transverse arc frame 11 in conjunction with the limit wheel 24. The operator observes the mark 14 through the viewing window 25 on the frame 21 to determine the transverse tilt angle. Then, the slider 31 of the sliding auxiliary adjustment mechanism 3 is moved along the longitudinal arc frame 29 to the appropriate angle, and then the positioning screw 315 is tightened to fix the slider. During the adjustment of the position of block 31, the second mark 210 is observed through the viewing window 316 on the slider 31 to determine the longitudinal tilt angle. Then, the image acquisition module 7 captures images of small parts on the assembly line in real time through the acquisition lens inside the monitoring tube 39 and transmits the image data to the comparison module 5. The comparison module 5 compares the acquired image with the preset standard part image and feeds back the comparison result to the main control module 4. If the comparison is consistent, the display module 26 displays the normal monitoring status. If the comparison is inconsistent, that is, there is a missed transmission, the main control module 4 immediately controls the warning module 27 to issue an alarm signal, and at the same time, the display module 26 displays the missed transmission abnormal information to remind the staff to deal with it in time.

[0044] During the above process, depending on the actual situation, the positioning rod 313 can be pulled to disengage it from the positioning groove 311 of the knob 310. Then, the knob 310 can be rotated to drive the adjusting shaft 33 to rotate, which in turn drives the adjusting gear 34 to rotate, which in turn drives the driven gear 36 to rotate, which in turn drives the mounting plate 37 to rotate, thereby realizing the adjustment of the compensation angle of the image acquisition module 7. After the adjustment is completed, the positioning rod 313 is released, and under the reset of the spring 314, the positioning rod 313 is pushed into the corresponding positioning groove 311 to lock the angle of the image acquisition module 7.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
