Description

Technical Field

[0001] This utility model relates to the technical field of fuel filter testing equipment, and in particular to an automatic testing and screening device for fuel filters. Background Technology

[0002] Fuel filters are common automotive components, primarily preventing impurities in the fuel from entering the fuel pump and causing blockages. After processing, fuel filters need to be inspected and screened. Currently, this is typically done in two ways: First, by visual inspection. However, this method has low accuracy; fuel filters require high precision, and some defects are difficult to discern with the naked eye, resulting in low reliability and efficiency. Second, by using a CCD vision inspection instrument. However, existing CCD vision inspection instruments typically only inspect one direction of the fuel filter, leading to incomplete inspection and potential oversights in blind spots, thus affecting the product's pass rate. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an automatic detection and screening device for fuel filters that improves detection accuracy and efficiency.

[0004] The technical solution of this utility model is as follows: An automatic detection and screening device for fuel filters, comprising a base, a fuel filter feeding device connected to the base, a rotating worktable connected to the base, a rotary motor for driving the rotating worktable, several CCD vision inspection devices connected to the base, a discharge device connected to the base, and an information processor and controller connected to the base. The fuel filter feeding device includes a rotating vibrating feed plate connected to the base, a flat vibrating track connected to the rotating vibrating feed plate, a flat vibrating motor for driving the flat vibrating track, a push rod slidably connected to the base, and a first hydraulic cylinder for driving the push rod to move horizontally. The upper surface of the flat vibrating track is at the same height as the upper surface of the rotating worktable. The push rod moves from the end of the flat vibrating track towards the center of the rotating worktable. The number of CCD vision inspection devices is greater than or equal to... The system comprises six rotating worktables made of glass. One CCD vision inspection instrument is located above the rotating worktable, one below it, and the remaining CCD vision inspection instruments are distributed around the rotating worktable. All CCD vision inspection instruments can perform 360-degree inspection of the fuel filter placed on the rotating worktable. The discharge device includes several discharge bins connected to the equipment base, a pushing assembly connected to the equipment base, and several photoelectric sensors connected to the equipment base. The number of pushing assemblies and photoelectric sensors are the same as the number of discharge bins. The movement direction of the pushing assembly is always along the line connecting the center of the rotating worktable to the discharge bin. The positions of the discharge bins correspond one-to-one with the positions of the pushing assemblies and photoelectric sensors. The controller is electrically connected to the vibration motor, CCD vision inspection instruments, information processor, rotating motor, first hydraulic cylinder, photoelectric sensors, and pushing assembly.

[0005] Using the above technical solution, firstly, the fuel filter to be inspected is fed into the vibrating track by a rotating vibrating feed plate. Then, the vibrating motor is controlled by the controller to provide vibration force to the vibrating track. The fuel filter to be processed is then transported to the end via the vibrating track. The first hydraulic cylinder is controlled by the controller to drive the push rod, thereby pushing the blocked fuel filter into the rotary table. Then, the rotary motor is controlled by the controller to rotate the rotary table, so that the fuel filter passes through each CCD vision inspection instrument in sequence. Since one CCD vision inspection instrument is located above the rotary table, one is located below the rotary table, and the remaining CCD vision inspection instruments are distributed around the rotary table, and... The CCD vision inspection instrument can perform 360-degree inspection of fuel filters placed on a rotating worktable. It captures images of the fuel filter from all angles, which are then compared with those of a standard fuel filter by an information processor to detect any defects. The processor then sends an electrical signal to the controller. When the fuel filter moves to the corresponding photoelectric sensor, the sensor simultaneously sends an electrical signal to the controller, which in turn controls the corresponding feeding assembly to push the fuel filter into the appropriate discharge bin. Compared to traditional fuel filter inspection devices, this significantly improves inspection accuracy and automation.

[0006] A further feature of this invention is that the pushing assembly includes an air blowing element connected to the equipment base, a connecting pipe connected to the air blowing element, and a blower connected to the connecting pipe. The air blowing direction of the air blowing element is respectively towards the direction of the discharge bin, and the controller is electrically connected to the blower.

[0007] Using the above technical solution, when the fuel filter moves to the corresponding discharge bin position, the photoelectric sensor sends an electrical signal to the controller. The controller controls the blower to send air through the connecting pipe to the air blowing element at the corresponding position. The airflow blown out by the air blowing element pushes the fuel filter into the corresponding discharge bin. This discharge method is more efficient and can reduce friction damage to the fuel filter during the discharge process.

[0008] A further feature of this invention is that the discharge bin includes a qualified product discharge bin connected to the equipment base, an end defective product discharge bin connected to the equipment base, and a side defective product discharge bin connected to the equipment base. The fuel filter entering the rotary table passes through the qualified product discharge bin, the end defective product discharge bin, and the side defective product discharge bin in sequence.

[0009] By adopting the above technical solution, since the discharge bin includes a qualified product discharge bin connected to the equipment base, an end defective product discharge bin connected to the equipment base, and a side defective product discharge bin connected to the equipment base, the fuel filter can be placed into the end defective product discharge bin or the side defective product discharge bin according to the detection results of the CCD vision inspection instrument. This can quickly find the defective product and greatly improve the efficiency of subsequent processing of defective products.

[0010] Further features of this invention: The discharge bin also includes a designated discharge bin connected to the equipment base and a guide plate connected to the equipment base. One end of the guide plate corresponds to the end position of the designated discharge bin, and the bottom of the guide plate is at the same level as the upper surface of the rotating worktable. The fuel filter entering the rotating worktable passes sequentially through the qualified product discharge bin, the end defective product discharge bin, the side defective product discharge bin, and the designated discharge bin.

[0011] Using the above technical solution, during the operation of the rotating worktable driving the fuel filter to rotate, the fuel filter may move too fast, resulting in insufficient image information captured by the CCD vision monitoring instrument, making it impossible to accurately determine whether there are defects on the fuel filter. The discharge bin also includes a pending discharge bin connected to the equipment base and a guide plate connected to the equipment base. Therefore, after the fuel filter passes through the qualified product discharge bin, the end defective product discharge bin, and the side defective product discharge bin, it will be automatically blocked by the guide plate and slide into the pending discharge bin to facilitate subsequent secondary inspection and ensure the inspection accuracy of this equipment.

Detailed Implementation

[0014] like Figure 1As shown, an automatic detection and screening device for fuel filters includes a base 1, a fuel filter feeding device 2 connected to the base 1, a rotary worktable 3 connected to the base 1, a rotary motor 4 for driving the rotary worktable 3 to rotate, several CCD vision inspection devices 5 connected to the base 1, a discharge device 6 connected to the base 1, an information processor 7 and a controller 8 connected to the base 1. The fuel filter feeding device 2 includes a rotating vibrating feed plate 9 connected to the base 1, a flat vibrating track 10 connected to the rotating vibrating feed plate 9, a flat vibrating motor 11 for driving the flat vibrating track 10 to vibrate, a push rod 12 slidably connected to the base 1, and a first hydraulic cylinder 13 for driving the push rod 12 to move horizontally. The upper surface of the flat vibrating track 10 is at the same height as the upper surface of the rotary worktable 3. The push rod 12 moves from the end of the flat vibrating track 10 towards the center of the rotary worktable 3. The number of CCD vision inspection devices is greater than or equal to 6. The worktable 3 is made of glass. One of the CCD vision inspection instruments 5 is located above the rotary worktable 3, and another is located below the rotary worktable 3. The remaining CCD vision inspection instruments 5 are distributed around the rotary worktable 3. All CCD vision inspection instruments 5 can perform 360-degree inspection of the fuel filter placed on the rotary worktable 3. The discharge device 6 includes several discharge bins 14 connected to the equipment base 1, a pusher assembly 15 connected to the equipment base 1, and several photoelectric sensors 16 connected to the equipment base 1. The number of pusher assemblies 15 and the number of photoelectric sensors 16 are the same as the number of discharge bins 14. The movement direction of the pusher assembly 15 is the line connecting the center of the rotary worktable 3 to the discharge bin 14. The positions of the discharge bins 14 correspond one-to-one with the positions of the pusher assembly 15 and the photoelectric sensors 16. The controller 8 is electrically connected to the vibration motor 11, the CCD vision inspection instrument 5, the information processor 7, the rotary motor 4, the first hydraulic cylinder 13, the photoelectric sensor 16, and the pusher assembly 15.

[0015] First, the fuel filter to be inspected is fed into the vibrating track 10 by the rotating vibrating feed plate 9. Then, the vibrating motor 11, controlled by the controller 8, provides vibration force to the vibrating track 10. The fuel filter to be processed is then transported to the end via the vibrating track 10. The first hydraulic cylinder 13, controlled by the controller 8, moves the push rod 12, thereby pushing the blocked fuel filter into the rotary table 3. Then, the rotary motor 4, controlled by the controller 8, rotates the rotary table 3, causing the fuel filter to pass through each CCD vision inspection instrument 5 in sequence. Since one CCD vision inspection instrument 5 is located above the rotary table 3, one is located below the rotary table 3, and the remaining CCD vision inspection instruments 5 are distributed around the rotary table 3, and... The CCD vision inspection instrument 5 can perform 360-degree inspection of the fuel filter placed on the rotating worktable 3. Therefore, the CCD vision inspection instrument 5 captures images of the fuel filter from all directions, and then the information processor 7 compares them with the fuel filter in a standard state to detect whether there are any defects in the fuel filter. Then, the information processor 7 sends an electrical signal to the controller 8. When the fuel filter moves to the corresponding photoelectric sensor 16, the photoelectric sensor 16 simultaneously sends an electrical signal to the controller 8. The controller 8 controls the corresponding pusher assembly 15 to push the fuel filter into the corresponding discharge bin 14. Compared with traditional fuel filter inspection devices, this greatly improves the inspection accuracy and the degree of automation of the inspection work.

[0016] The feeding assembly 15 includes an air blowing element 17 connected to the equipment base 1, a connecting pipe 18 connected to the air blowing element 17, and a blower 19 connected to the connecting pipe 18. The air blowing direction of the air blowing element 17 is towards the discharge bin 14. The controller 8 is electrically connected to the blower 19.

[0017] When the fuel filter moves to the corresponding discharge bin 14, the photoelectric sensor 16 sends an electrical signal to the controller 8. The controller 8 controls the blower 19 to send air through the connecting pipe 18 to the air blowing element 17 at the corresponding position. The airflow blown out by the air blowing element 17 pushes the fuel filter into the corresponding discharge bin 14. This discharge method is more efficient and can reduce friction damage to the fuel filter during the discharge process.

[0018] The discharge bin 14 includes a qualified product discharge bin 20 connected to the equipment base 1, an end defective product discharge bin 21 connected to the equipment base 1, and a side defective product discharge bin 22 connected to the equipment base 1. The fuel filter entering the rotary worktable 3 passes through the qualified product discharge bin 20, the end defective product discharge bin 21, and the side defective product discharge bin 22 in sequence.

[0019] Since the discharge bin 14 includes a qualified product discharge bin 20 connected to the equipment base 1, an end defective product discharge bin 21 connected to the equipment base 1, and a side defective product discharge bin 22 connected to the equipment base 1, the fuel filter can be placed into the end defective product discharge bin 21 or the side defective product discharge bin 22 according to the detection results of the CCD vision inspection instrument 5. This can quickly find the defective product and greatly improve the efficiency of subsequent processing of defective products.

[0020] The discharge bin 14 also includes a designated discharge bin 23 connected to the equipment base 1 and a guide plate 24 connected to the equipment base 1. One end of the guide plate 24 corresponds to the end position of the designated discharge bin 23. The bottom of the guide plate 24 is at the same level as the upper surface of the rotary worktable 3. The fuel filter entering the rotary worktable 3 passes sequentially through the qualified product discharge bin 20, the end defective product discharge bin 21, the side defective product discharge bin 22, and the designated discharge bin 23.

[0021] During the operation of the rotating worktable 3 driving the fuel filter to rotate, the fuel filter may move too fast, resulting in insufficient image information captured by the CCD vision monitoring instrument, making it impossible to accurately determine whether there are defects on the fuel filter. The discharge bin 14 also includes a pending discharge bin 23 connected to the equipment base 1 and a guide plate 24 connected to the equipment base 1. Therefore, after the fuel filter passes through the qualified product discharge bin 20, the end defective product discharge bin 21, and the side defective product discharge bin 22, it will be automatically blocked by the guide plate 24 and slide into the pending discharge bin 23 to facilitate subsequent secondary inspection and ensure the inspection accuracy of this equipment.
