Description

Technical Field

[0001] This utility model relates to the field of piston sorting technology, and more specifically, to an automatic sorting device for piston assembly assembly defects. Background Technology

[0002] The automotive braking system is the most important safety system in a car, and the master cylinder, as the energy conversion and output device, is the heart of the entire braking system. The assembly of the first and second piston components and spring components of the master cylinder is a crucial step in the production and assembly of the automotive braking system. Its assembly quality directly affects the engine's power consumption, stability, and lifespan. Therefore, as a critical step before piston assembly, its assembly quality must be 100% inspected.

[0003] Currently, online inspection of piston assembly quality mostly relies on manual methods. Inspectors need to use simple tools such as calipers and plug gauges, as well as visual observation, to complete each inspection item in sequence. This leads to unstable inspection accuracy. On the one hand, manual inspection is highly subjective, with differences in operating techniques, experience levels, and concentration among different inspectors. It is difficult to completely unify the judgment criteria for the same defect, which can easily result in "missing qualified parts and misjudging unqualified parts". On the other hand, long-term repetitive inspection can easily cause personnel fatigue, further reducing the inspection accuracy. In particular, the identification ability of manual inspection is significantly limited when dealing with micron-level dimensional deviations or hidden assembly defects. Utility Model Content

[0006] A conveying assembly is provided between the multiple support plates, two sets of detection assemblies are provided at the middle position of the top side of the rectangular base plate, and a sorting assembly is provided between two of the support plates near the rectangular base plate. The piston assembly is conveyed by the conveying assembly, and during the conveying process, the piston assembly is detected by the detection assemblies on both sides, and the piston assembly is sorted by the sorting assembly.

[0007] As a further improvement to this technical solution, the conveying assembly includes two receiving plates, a rotating shaft is rotatably connected between the two receiving plates, and the two rotating shafts are arranged far apart from each other. A rotating cylinder is fixedly sleeved on the outside of each rotating shaft, and a transmission belt is drivenly connected to the outside of the two rotating cylinders. Multiple hooks are fixedly connected to the outside of the transmission belt, and the multiple hooks are arranged far apart from each other.

[0008] As a further improvement to this technical solution, a drive motor is fixedly installed on one side of one of the receiving plates, and the output shaft of the drive motor is fixedly connected to one end of one of the rotating shafts. Two connecting plates are fixedly connected to one side of each of the two receiving plates, and the two connecting plates are arranged far apart from each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In automated sorting equipment for piston assembly defects, existing piston inspection and sorting are mostly done manually, which inevitably leads to omissions. By setting up a conveying component to transport the piston assembly, two sets of inspection components inspect the appearance of the piston assembly during the transport process to ensure its integrity. When a piston assembly with defects is encountered, the two inspection components transmit the data to the data processor, which drives the sorting component to sort the piston assembly. This achieves the effect of conveying, inspection, and sorting, avoiding omissions in manual inspection and sorting, and also increasing the inspection efficiency of piston assemblies.

[0023] Please see Figures 1-5As shown, this embodiment provides an automatic sorting device for piston assembly assembly defects, including a rectangular base plate 100. Support feet are fixedly connected to the four corners of the bottom side of the rectangular base plate 100, and support plates 200 are fixedly connected to the four corners of the top side of the rectangular base plate 100. The same data processor 300 is fixedly connected to the top side of multiple support plates 200. A display screen 400 and multiple buttons 500 are provided on one side of the data processor 300.

[0024] A conveying assembly 600 is arranged between multiple support plates 200, two sets of detection assemblies 700 are arranged at the middle position of the top side of the rectangular base plate 100, and a sorting assembly 800 is arranged between two support plates 200 near the rectangular base plate 100. The piston assembly is conveyed by the conveying assembly 600, and during the conveying process, the piston assembly is detected by the two sets of detection assemblies 700 and sorted by the sorting assembly 800.

[0025] In practical applications, the equipment is powered on, and parameters are set via the display screen 400 and multiple buttons 500. Then, the piston assembly is manually hung on the conveying assembly 600, which transports the piston assembly. During the transport process, two sets of detection assemblies 700 inspect the appearance of the piston assembly. When a piston assembly with defects is encountered, the two detection assemblies 700 transmit the data to the data processor 300, which then drives the sorting assembly 800 to sort the piston assembly. This achieves the functions of conveying, inspection, and sorting.

[0026] Please see Figures 1-3 As shown, the conveying assembly 600 includes two receiving plates 601, with a rotating shaft 602 rotatably connected between them. The two rotating shafts 602 are arranged far apart from each other. A rotating cylinder 603 is fixedly sleeved on the outside of each rotating shaft 602. A transmission belt 604 is drivenly connected to the outside of the two rotating cylinders 603. Multiple hooks 605 are fixedly connected to the outside of the transmission belt 604. The multiple hooks 605 are arranged far apart from each other. A drive motor 606 is fixedly installed on one side of one of the receiving plates 601. The output shaft of the drive motor 606 is fixedly connected to one end of one of the rotating shafts 602. Two connecting plates 607 are fixedly connected to one side of each of the two receiving plates 601. The two connecting plates 607 are arranged far apart from each other. The multiple connecting plates 607 are respectively fixedly connected to one side of multiple support plates 200.

[0027] In practical applications, the piston assembly is manually hung on the corresponding hook 605. The data processor 300 sends a command to the drive motor 606, which drives one of the rotating shafts 602 and the rotating drum 603 to rotate. At the same time, the drive belt 604 drives the transmission outside the two rotating drums 603, which drives multiple hooks 605 to move. By rotating the drive motor 606 clockwise, the piston assembly can be transported.

[0028] Please see Figure 1 and Figure 4 As shown, each detection component 700 includes two arc-shaped support plates 701. The two arc-shaped support plates 701 are fixedly connected to the top side of the rectangular base plate 100, and the two arc-shaped support plates 701 are arranged far apart from each other. The top of the two arc-shaped support plates 701 is fixedly connected to the same arc-shaped mounting plate 702. Multiple infrared cameras 703 are fixedly installed on the inner side of the arc-shaped mounting plate 702, and the multiple infrared cameras 703 are arranged far apart from each other.

[0029] In practical applications, during the conveying process of the piston assembly, in order to avoid blind spots in the appearance scanning, both arc-shaped mounting plates 702 are set in an arc shape. Multiple infrared cameras 703 set on the inner side of the two arc-shaped mounting plates 702 perform appearance scanning on the conveying piston assembly and transmit the image data to the data processor 300. The data processor 300 compares and processes the image data to complete the inspection of the appearance of the piston assembly.

[0030] Please see Figure 1 and Figure 5 As shown, the sorting assembly 800 includes a one-way threaded rod 801, which is rotatably connected between and through two support plates 200. Two threaded sliding blocks 802 are threadedly connected to the outer side of the one-way threaded rod 801. The two threaded sliding blocks 802 slide along the top side of the rectangular base plate 100, while the top side of the rectangular base plate 100 limits the two threaded sliding blocks 802. A sorting bucket 803 is fixedly connected to the two threaded sliding blocks 802. A sorting motor 804 is fixedly installed on one side of one of the support plates 200. The output shaft of the sorting motor 804 is fixedly connected to one end of the one-way threaded rod 801.

[0031] In practical applications, when the two sets of detection components 700 perform visual inspection on the defective piston components, the data processor 300 controls the sorting motor 804 to drive the one-way threaded rod 801 to rotate, and the one-way threaded rod 801 drives the sorting bucket 803 to move through the two threaded sliding blocks 802, so that the sorting bucket 803 can separate and collect good products and defective products.

[0032] Working principle: Before starting the equipment, the operator sets parameters (such as conveying speed, detection accuracy, etc.) via button 500. This operation signal is transmitted to the data processor 300 via a serial communication line. The data processor 300 simultaneously sends the parameter information to the display screen 400 for visual display through the same channel. During operation, the operator hangs the piston assembly on the hook 605 of the conveying assembly 600. The data processor 300 sends start and speed control commands to the drive motor 606 via the servo motor control bus. The drive motor 606 responds to the commands and drives the conveying assembly 600 to move, realizing the conveying of the piston assembly. When the piston assembly passes the detection assembly 700, multiple infrared cameras 703 on the inner side of the arc-shaped mounting plate 702 of the two sets of detection assemblies 700... Simultaneously, an appearance scan is initiated, and the collected image data of the piston assembly is uploaded in real time to the data processor 300 via an industrial Ethernet bus or high-definition video transmission line. The data processor 300 compares and processes the image data using a built-in image recognition algorithm to determine defects. If a defective product is determined, the data processor 300 immediately sends a steering and rotation angle control command to the sorting motor 804 of the sorting component 800 via the servo motor control bus. The command drives the one-way threaded rod 801 to rotate and moves the sorting bucket 803 to the designated sorting position. At the same time, the data processor 300 transmits the inspection results (good / defective products) and equipment operating status to the display screen 400 via a serial port, realizing real-time transmission and closed-loop control of data throughout the entire process.
