Description

Technical Field

[0001] The present invention relates to the technical field of appearance detection, and in particular to a device for detecting appearance defects of a spin-on oil filter of an internal combustion engine. Background Art

[0002] In the production process of internal combustion engine spin-on oil filters, appearance defect detection is a key link in ensuring product quality. Currently, the industry relies on manual visual inspection or automated detection using camera probes to detect appearance defects in oil filters.

[0003] Among them, when using camera probes for automated detection, due to the cylindrical structure of the filter, the detection viewing angles of different parts vary greatly. In order to improve detection efficiency and accuracy, it is usually necessary to set camera probes on multiple key parts such as the circumferential side, upper and lower end faces of the oil filter for comprehensive scanning to cover different detection areas respectively. In actual use, this detection method with multiple probes set up in a dispersed manner has obvious shortcomings: on the one hand, the installation position and angle of each probe need to be adjusted individually according to the detection requirements, which increases the difficulty of equipment debugging and maintenance; on the other hand, the use of a large number of detection probes directly increases the hardware cost of the equipment, and also increases the load of data acquisition and processing, which is not conducive to the efficient operation and cost control of the detection system.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a plurality of carrier units are distributed in a circular manner within a rail frame, and a first horizontal track and a second horizontal track with a height difference are formed on the left and right sides of the rail frame. The carrier units carrying the oil filter are driven to move upright on the first horizontal track, and driven to move inverted on the second horizontal track with the oil filter. This allows the camera probe in the middle position to capture the appearance of the oil filter from two different directions, upper and lower, without adjustment, to perform appearance defect detection. The operation is convenient and efficient, which can effectively improve the detection accuracy. Moreover, it is unnecessary to set up multiple camera probes, which can effectively reduce the detection cost. 2. In the present invention, the support wheels are rotatably mounted on the left and right sides of the frame in the carrier unit, and a first baffle is provided at the bottom of the first horizontal track to guide the support wheels, a second baffle is provided at the top of the second horizontal track to guide the support wheels, and a third baffle and an arc-shaped guide plate are provided to cooperate with each other. The support wheels are continuously guided at the left end of the horizontal vertical section at the bottom of the rail frame. Under the action of gravity and the center of gravity, when the carrier unit moves around in the rail frame, it can automatically be in an upright state at the first horizontal track and automatically turn into an inverted state at the second horizontal track. No manual operation or adjustment by the staff is required, which can effectively ensure the flexibility of use and operational stability of the device. 3. In the present invention, the truncated cone-shaped structure provided at the end of the insertion rod is squeezed between a plurality of surrounding elastic plates under the elastic support of the spring, so that the elastic plates are supported outward, thereby realizing the fastening of the oil filter by the connecting mechanism. By installing magnets that magnetically repel the slider at the lower position in the loading area and the upper position in the unloading area, after the carrier unit enters the loading and unloading areas, the magnetic repulsion between the magnet and the slider automatically releases the fastening state of the connecting mechanism, which can effectively improve the operational convenience when loading and unloading the oil filter during the operation of the device and is conducive to improving the detection efficiency. 4. In the present invention, by rotatably connecting the column rod to the vehicle frame and installing a rack rod adapted to the gear at a lower position within the first inspection area and an upper position within the second inspection area, when the carrier unit carries the oil filter and moves within the first inspection area and the second inspection area, the column rod can be driven to rotate the oil filter by virtue of the meshing of the gear and the rack rod at the corresponding position, the transmission of the transmission rod, and the meshing of the first bevel gear and the second bevel gear. This allows the camera probe to perform a more comprehensive appearance photography inspection of the oil filter within the first inspection area and the second inspection area, effectively improving the comprehensiveness of appearance defect inspection and thereby facilitating improved inspection accuracy. 5. In the present invention, a transmission belt connected to rollers in a plurality of transport units is installed in a circular manner in a rail frame and driven by the rotation of a wheel disc, so that the device can uniformly pull a plurality of transport units to move in an orderly manner. By evenly opening a plurality of air holes in the contact surface of the rail frame with the transmission belt and supplying air with the help of an air pipe, the air flow ejected from the air holes can form a high-speed air flow layer between the transmission belt and the rail frame. With the help of the Bernoulli effect, the stability and smooth movement of the transmission belt installed in the rail frame can be effectively guaranteed. At the same time, the air flow ejected outward from the air holes can also act on the path of movement of the transport unit, blowing away dust and impurities floating in the surrounding environment of the device, which can effectively ensure the detection accuracy of the device during operation.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example: This embodiment provides an internal combustion engine spin-on oil filter appearance defect detection device, see Figure 1 - Figure 12Specifically, it includes a rail frame 1 arranged around, the upper left side of the rail frame 1 is set as a first cross section 101, the upper right side of the rail frame 1 is set as a second cross section 102, and the second cross section 102 is set above the first cross section 101, a loading area 103 is set on the left side of the first cross section 101, a first detection area 104 is set on the right side of the first cross section 101, a second detection area 105 is set on the left side of the second cross section 102, and a discharge area 106 is set on the right side of the second cross section 102. There are transport units distributed in a surrounding manner, and the transport units include a frame 2 movably arranged in the rail frame 1, and the front and rear sides of the frame 2 coaxially rotate with rollers 201 installed in the rail frame 1. A connecting mechanism is installed on the top of the frame 2, and a driving mechanism is installed in the rail frame 1. The transport units located in the first horizontal track 101 area are in a vertically upward state, and the transport units located in the second horizontal track 102 area are in a vertically downward state. A camera probe is installed on the front of the rail frame 1 at a position between the first detection area 104 and the second detection area 105.

[0021] During the operation of the device, the staff uses the device to perform defect detection on the appearance of the internal combustion engine spin-on oil filter. When the driving mechanism in the device is started, it will pull the carrier unit, and the roller 201 will roll on the rail frame 1, so that the carrier unit will move around in the rail frame 1. The distances between the multiple carrier units are equal. The staff can load the oil filter from the loading area 103 to the top of the frame 2 through the connecting mechanism installed on the top of the frame 2. When the carrier unit carries the oil filter on the first horizontal track 1 01, the carrier unit is in a vertically upright position, at which time the oil filter connected to the carrier unit is in an upright position, thereby causing the oil filter to be in an upright position when in the first detection area 104; when the carrier unit carries the oil filter and moves on the second horizontal track 102, the carrier unit is in a vertically downward inverted position, at which time the oil filter connected to the carrier unit is in an inverted position, thereby causing the oil filter to be in an inverted position when in the second detection area 105.

[0022] In the device, the second cross section 102 is located above the first cross section 101. This allows the oil filter to stand upright in the first detection area 104 and be inverted in the second detection area 105. However, due to the height difference between the first cross section 101 and the second cross section 102, the oil filter standing upright in the first detection area 104 can maintain the same height as the oil filter inverted in the second detection area 105. The camera probe installed between the first detection area 104 and the second detection area 105 is at the same height as the first detection area 104. The position above the oil filter in the testing area 104 and the second testing area 105 allows the camera probe to shoot and test the oil filter in the first testing area 104 from the top of the oil filter, and to shoot and test the oil filter in the second testing area 105 from the bottom of the oil filter. The camera probe can simultaneously perform appearance defect detection on the oil filters in two different states in the first testing area 104 and the second testing area 105.

[0023] After the inspection is completed, the oil filter is detached and removed from the unloading area 106, and the carrying unit circulates in the rail frame 1, continuously transporting the oil filter through the first inspection area 104 and the second inspection area 105 for inspection. The device uses a single camera probe to perform appearance defect inspection on the oil filter, and when the position of the camera probe does not need to be moved and adjusted, the appearance of the oil filter can be inspected for defects from two different directions, the upper and lower, which can effectively improve the inspection accuracy, and there is no need to set up multiple camera probes, which can effectively reduce the inspection cost.

[0024] In the specific implementation process, Figure 10 - Figure 12 As shown, the connecting mechanism includes a column 3, and a plurality of elastic plates 301 distributed around the end position of the column 3 are fixed, and an insertion rod 302 running through the plurality of elastic plates 301 is slidably inserted at the central axis position in the column 3, and the end of the insertion rod 302 away from the column 3 is set to a truncated cone structure, and the end of the plurality of elastic plates 301 away from the column 3 is gathered toward the insertion rod 302, and a slider 303 slidably installed in the column 3 is fixed on the insertion rod 302, and a spring 304 for elastically supporting the slider 303 is installed on the side of the column 3 close to the elastic plate 301.

[0025] During the operation of the device, when the connecting mechanism is used to firmly connect the oil filter to the carrier unit, the staff manipulates the insertion rod 302 to overcome the elastic support of the spring 304, so that the insertion rod 302 moves in the direction away from the column 3, so that the truncated cone structure at the end of the insertion rod 302 withdraws from the many surrounding elastic plates 301, and the end of the many elastic plates 301 converges toward the central axis of the column 3 again, making it present a cone structure as a whole. Then the staff puts the oil filter The connecting port at the bottom of the filter is aligned with the column 3, and the connecting port at the bottom of the oil filter is placed on the outside of the elastic plate 301 fixed around the end of the column 3. Subsequently, the control of the insertion rod 302 is released. Under the elastic reset support of the spring 304, the insertion rod 302 drives the truncated cone structure at its end to be reinserted between the many surrounding elastic plates 301. Under the support of the truncated cone structure, the many elastic plates 301 expand outward and are supported in the connecting port at the bottom of the oil filter, firmly connecting the oil filter to the frame 2.

[0026] In the specific implementation process, Figure 1 、 Figure 3 and Figure 8 As shown, there is an inclined transition between the first cross track 101 and the second cross track 102, and support wheels 202 located on the left and right sides of the roller 201 are rotated in the frame 2, a first baffle 5 is fixed under the first cross track 101, and a second baffle 501 is fixed above the second cross track 102, and the column 3 is vertically installed at the top middle position of the frame 2, and the central axis of the column 3 is in the same plane and perpendicular to the central axis of the roller 201, and a counterweight 203 is fixed on the top of the frame 2.

[0027] When the transport unit moves in the area of ​​the first cross track 101, the first baffle 5 provided below the first cross track 101 can support the support wheels 202 rotatably installed on the left and right sides of the frame 2 in the transport unit from the lower position, so that the transport unit maintains a stable vertical upward state when moving in the first cross track 101. When the transport unit crosses the first cross track 101 and arrives at the inclined transition section between the first cross track 101 and the second cross track 102, the support wheels 202 on the left and right sides of the frame 2 are no longer supported. Under the influence of gravity and the center of gravity, the transport unit drives the oil filter connected thereto to automatically flip downward and present a vertical downward state. When the transport unit moves in the second cross track 102, the second baffle 501 provided above the second cross track 102 can support the support wheels 202 rotatably installed on the left and right sides of the frame 2 in the transport unit from the upper position, thereby ensuring the stability of the inverted movement of the transport unit carrying the oil filter in the area of ​​the second cross track 102.

[0028] In this device, by setting the central axis of the column 3 and the central axis of the roller 201 in the same plane and perpendicular to each other, the center of gravity of the carrier unit is maintained on the central axis of the column 3 regardless of whether the oil filter is connected to the carrier unit through the connecting mechanism. This is beneficial to ensuring the stability of the carrier unit when it is flipped downward by gravity and during continuous movement after being flipped upside down.

[0029] In the specific implementation process, Figure 3 and Figure 8 As shown, a third baffle 502 is fixed at the lower left end of the rail frame 1, and an arc-shaped guide plate 503 connected between the third baffle 502 and the first baffle 5 is fixed at the left end of the rail frame 1. The right end of the third baffle 502 is set to an upwardly inclined structure. During the operation of the device, when the carrier unit continues to move after crossing the second cross-track 102 area, it will move to the horizontal section at the bottom of the rail frame 1. In this process, due to the traction of the driving mechanism and the guidance of the surrounding rail frame 1, the carrier unit is moved from the first cross-track 101 and the second cross-track 102. The movement from left to right is transformed into movement from right to left. Affected by gravity and center of gravity, the carrier unit remains in an inverted state when moving on the horizontal and vertical section at the bottom of the track frame 1. When the carrier unit moves to the left side of the horizontal and vertical section at the bottom of the track frame 1, the support wheels 202 rotatably installed on the left and right sides of the frame 2 in the carrier unit will be supported and restricted by the third baffle 502 set above it. In the subsequent movement process, the carrier unit is continuously guided by the third baffle 502 and the arc-shaped guide plate 503, so that when it moves into the first horizontal track 101 area, it will be converted into a vertical upward state.

[0030] In the device, the support wheels 202 are rotatably installed on the left and right sides of the frame 2 in the carrier unit, and the support wheels 202 are guided at the bottom of the first cross track 101 by means of the first baffle 5, and are guided at the top of the second cross track 102 by means of the second baffle 501. The support wheels 202 are continuously guided at the left end of the horizontal and vertical section at the bottom of the track frame 1 by means of the third baffle 502 and the arc-shaped guide plate 503. In combination with the effects of gravity and center of gravity, when the carrier unit moves around in the track frame 1, it can automatically be in an upright state at the first cross track 101 and automatically change to an inverted state at the second cross track 102. No manual operation and adjustment by staff is required, which can effectively ensure the flexibility of use and operational stability of the device.

[0031] In this device, by setting the right end of the third baffle 502 to an upwardly inclined structure, when the transport unit moves from right to left in the horizontal and vertical section at the bottom of the rail frame 1 to below the third baffle 502, the right end of the third baffle 502 can tilt and guide the entry of the support wheel 202, so that the transport unit can enter below the third baffle 502 more smoothly, which is conducive to further ensuring the operational stability of the device.

[0032] In the specific implementation process, Figure 3 - Figure 5 As shown, magnets 504 are installed in the loading area 103 and the unloading area 106. The magnet 504 in the loading area 103 is fixed below the first horizontal track 101, and the magnet 504 in the unloading area 106 is fixed above the second horizontal track 102. The magnet 504 and the slider 303 magnetically repel each other. During the operation of the device, when the carrier unit moves to the loading area 103 and the unloading area 106, the connecting mechanism will automatically release the fastening of the oil filter under the magnetic repulsion between the magnet 504 and the slider 303, which can effectively improve the convenience of loading and unloading operations when the staff uses the device to detect appearance defects of the oil filter.

[0033] The structure between the slider 303 and the magnet 504 on the carrier unit is made of non-magnetic materials such as aluminum, copper or engineering plastics. The slider 303 is made of magnets. When the carrier unit moves to the loading area 103, the magnet 504 installed below the first horizontal track 101 generates a magnetic repulsive force against the slider 303 in the connecting mechanism on the carrier unit above it, so that the slider 303 drives the insertion rod 302 to overcome the elastic support of the spring 304 and move upward. The insertion rod 302 is controlled to move upward, and its end is provided with a magnetic repulsive force. The truncated cone-shaped structure is withdrawn from between the numerous surrounding elastic plates 301, so that the ends of the numerous surrounding elastic plates 301 are gathered in the loading area 103, making it convenient for the staff to plug the oil filter into the elastic plate 301. When the carrier unit moves out of the loading area 103, the slider 303 in the internal connection mechanism is no longer affected by the magnetic repulsion of the magnet 504, and is reset under the elastic support of the spring 304, pushing the elastic plate 301 outward to achieve a fastened connection to the oil filter.

[0034] Similarly, when the carrier unit moves into the unloading area 106, the magnet 504 installed above the second horizontal track 102 generates a magnetic repulsive force on the slider 303 in the connecting mechanism on the carrier unit below it, so that the slider 303 drives the insertion rod 302 to overcome the elastic support of the spring 304 and move downward. The insertion rod 302 is controlled to move downward in the inverted connecting mechanism, releasing the expansion of the ends of the numerous elastic plates 301 from the inside to the outside, thereby releasing the fastening connection of the connecting mechanism to the oil filter, facilitating the unloading operation.

[0035] In the specific implementation process, Figure 3 - Figure 5 and Figure 12 As shown, the column 3 is rotatably connected to the frame 2, and a transmission rod 4 located on the central axis of the roller 201 rotates inside the frame 2, and a gear 401 and a first bevel tooth 402 are fixed to the transmission rod 4, and a second bevel tooth 403 engaged with the first bevel tooth 402 is fixed to the column 3, and a rack rod 505 is installed in both the first detection area 104 and the second detection area 105, and the rack rod 505 is adapted to the gear 401, the rack rod 505 located in the first detection area 104 is fixed below the first horizontal track 101, and the rack rod 505 located in the second detection area 105 is fixed above the second horizontal track 102.

[0036] During the operation of the device, when the carrier unit moves in the first inspection area 104 and the second inspection area 105, the gear 401 will engage with the rack rod 505. As the carrier unit continues to move, and with the help of the engagement of the gear 401 and the rack rod 505 at the corresponding position, the gear 401 can drive the transmission rod 4 to rotate, and then with the help of the engagement of the first bevel gear 402 and the second bevel gear 403, the column rod 3 is driven to rotate, thereby driving the oil filter connected to the connecting structure to rotate. The above-mentioned structural arrangement allows the oil filter to automatically rotate when it is carried by the carrier unit through the first inspection area 104 and the second inspection area 105, so that the camera probe can perform a more comprehensive appearance shooting inspection of the oil filter in the first inspection area 104 and the second inspection area 105, which can effectively improve the comprehensiveness of appearance defect detection and thus help improve detection accuracy.

[0037] In the specific implementation process, Figure 4 - Figure 7 and Figure 9 As shown, the driving mechanism includes a wheel disc 6 rotatably mounted in the left end of the rail frame 1, a servo motor 601 for driving the wheel disc 6 to rotate is fixed to the rear of the rail frame 1, a transmission belt 602 is slidably mounted on the outside of the wheel disc 6 in the rail frame 1, and a connecting frame rotatably connected to the roller 201 is fixed on the transmission belt 602, air holes 603 corresponding to the transmission belt 602 are distributed around the end wall of the rail frame 1, and an air pipe 604 connected to a plurality of air holes 603 is fixed on the side of the end wall of the rail frame 1 away from the transmission belt 602, and the air pipe 604 is externally connected to an air pump. During the operation of the device, when the driving mechanism is used to pull a plurality of carrier units to move around in an orderly manner in the rail frame 1, the servo motor 601 is powered on and started, which will drive The wheel 6 connected to its drive shaft rotates, and the rotation of the wheel 6 drives the transmission belt 602 to move around in the rail frame 1, and the connection between the roller 201 and the transmission belt 602 is connected by the connecting frame, so as to pull the carrying unit to move in the rail frame 1. During the movement of the transmission belt 602, the air pump connected to the air pipe 604 is powered on and started, providing a high-speed air flow in the air pipe 604. The air flow is blown out through the air hole 603 and acts on the contact surface between the transmission belt 602 and the rail frame 1, forming a high-speed air flow layer between the transmission belt 602 and the rail frame 1. With the help of the Bernoulli effect, the transmission belt 602 is firmly installed in the rail frame 1, and the smoothness of the transmission belt 602 during rotation and movement can be guaranteed.

[0038] At the same time, high-speed airflow is ejected outward through numerous surrounding air holes 603, acting on the path of movement of the carrier unit. The airflow can blow away dust and impurities floating in the surrounding environment of the device, preventing dust and impurities from adhering to the oil filter. This not only prevents dust and impurities from interfering with the appearance defect detection of the oil filter, but also ensures the appearance cleanliness of the oil filter after detection, which is beneficial to ensuring the quality of the product after detection.

[0039] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
