Description

Technical Field

[0001] This invention relates to the field of foreign object detection, and specifically to a foreign object detection device for box-type parts. Background Technology

[0002] For some box-type parts, such as high-voltage wiring boxes for automobiles, it is necessary to inspect the interior of the box for foreign objects after production and processing to avoid adverse effects caused by foreign objects inside the box. For example, if there are metal wires or metal shavings inside the high-voltage wiring box, it may cause a short circuit in the wiring inside the high-voltage wiring box during later use.

[0003] In existing technologies, foreign objects inside the box are detected visually. A high-definition camera is used to photograph the inside of the box, and the captured images are sent back to a computer for analysis to determine whether there are foreign objects inside the box.

[0004] Existing detection equipment can only detect foreign objects visually. Once detected, the object needs to be transferred to a cleaning device for additional cleaning or manually removed, making automated removal impossible. Furthermore, if these foreign objects are hidden in corners inside the container or in horizontal openings, the camera cannot capture them, thus affecting the detection results. Summary of the Invention

[0005] The present invention aims to provide a foreign object detection device for box-type parts, which has the function of foreign object cleaning, thus solving the problem that the prior art does not have the function of foreign object cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foreign object detection device for box-type parts, including a camera, and further comprising, A rotating component, which is provided with a fixing component for fixing the box body to the rotating component; A drive component used to drive rotating parts to flip; And a suction component, which includes a movable suction box with negative pressure inside; The relative states of the camera and the inside of the box, and the relative states of the inside of the box and the suction box are changed by rotating the rotating parts; when the suction box is relative to the inside of the box, the suction box moves onto the box and the suction box covers the box.

[0007] The principle and advantages of this solution are as follows: The box is placed on a rotating component, and a fixing component secures the box to the rotating component. A driving component drives the rotating component to rotate. Because the fixing component secures the box, it will not fall off the rotating component. The rotation of the rotating component causes the box to rotate along with it, thus changing the relative states of the camera and the inside of the box, and the relative states of the inside of the box and the suction box. When the camera is relative to the inside of the box, it takes a picture of the inside, thus detecting foreign objects inside. When the suction box is relative to the inside of the box, it moves closer to the box and closes its lid. Due to the negative pressure inside the suction box, it sucks up the foreign objects inside the box, removing them from the box.

[0008] This solution offers the following benefits: 1. This equipment can not only detect foreign objects through visual inspection, but also suck up foreign objects inside the box to clean them up, thus achieving automatic cleaning of foreign objects.

[0009] 2. Using suction to clean foreign objects, compared to blowing air to clean foreign objects inside the box, will not cause foreign objects to fly around, thus ensuring the quality of cleaning and preventing foreign objects from splashing into the surrounding environment and causing adverse effects.

[0010] 3. By rotating the component, the relative states of the camera and the inside of the box, as well as the relative states of the inside of the box and the suction box, are changed. During the rotation of the component, the box will shake, which helps to loosen or displace foreign objects in the box. This makes it easier for the suction box to suck out foreign objects from the box.

[0011] Preferably, as an improvement, the rotating component is located between the camera and the suction box.

[0012] Preferably, as an improvement, the camera is located above the suction box.

[0013] Preferably, as an improvement, the suction component further includes a movable plate, a drive unit for moving the movable plate, and a suction box fixedly located on the movable plate.

[0014] Therefore, by driving the moving plate through the driving component, the moving plate moves, and the moving plate moves the suction box together, thereby moving the suction box away from or closer to the box body.

[0015] Preferably, as an improvement, the suction component also includes a negative pressure machine for generating negative pressure within the suction box.

[0016] Thus, negative pressure is generated inside the suction box by using a negative pressure machine.

[0017] Preferably, as an improvement, the negative pressure unit can be located on the movable plate and move with the movable plate; or, the negative pressure unit is located outside the movable plate, and a negative pressure hose is connected to the negative pressure unit, which is connected to the suction box.

[0018] Preferably, as an improvement, the rotating component includes a rotating plate and a support block fixed on the rotating plate.

[0019] Therefore, by supporting the support block with the rotating plate and fixing the box, the box is placed on the support block, and the fixing component presses down on the box located on the support block, thereby fixing the box.

[0020] Preferably, as an improvement, at least two sealing plates are movably connected to the rotating plate, and the multiple sealing plates seal the pipe holes on the box body; the opening and sealing states of the pipe holes are switched by moving the sealing plates.

[0021] The boxes can have different shapes and structures. Some boxes have at least two horizontal pipe holes. When cleaning foreign objects from such boxes, the sealing plates block the pipe holes on the box. By moving part of the sealing plates, some pipe holes are opened while the other pipe holes remain blocked. By controlling different sealing plates, different pipe holes can be opened or blocked.

[0022] Without the above improvements, when cleaning foreign objects from a box with at least two horizontal pipe holes, the suction box draws in foreign objects from the box. External air enters the box through the pipe holes and then into the suction box. With a constant suction speed, the pipe holes will disperse the speed or amount of gas entering the suction box. In other words, the more pipe holes there are, the lower the air intake speed or volume of each pipe hole, and the smaller the airflow in each pipe hole. This makes it difficult to clean foreign objects from the pipe holes and to remove firmly attached foreign objects from the inner wall of the pipe holes.

[0023] This solution, by partially sealing and partially opening the pipe holes, reduces the number of open holes. With a constant suction speed, it increases the velocity or volume of gas entering the pipe holes, resulting in more abundant gas flow or a stronger airflow. This allows for more thorough agitation of foreign objects within the pipe holes, increasing the success rate of removing firmly attached foreign objects from the inner walls of the holes and improving the overall cleaning effect.

[0024] By sealing or opening different pipe holes, it is possible to clean different pipe holes.

[0025] Preferably, as an improvement, the movement of the sealing plate is controlled so that only one orifice is open at a time, while the others are blocked. Thus, only one orifice is open at any given time, while the others are blocked. This ensures that gas entering the housing enters through only one orifice at a time, resulting in a larger airflow and better removal of foreign matter from the orifice compared to gas entering through two or more orifices.

[0026] Preferably, as an improvement, each of the sealing plates is fixedly connected to a sliding part, the sliding part is slidably connected to the rotating plate, and each of the sliding parts is fixedly connected to a wedge. The wedge is located on the side of the rotating plate away from the box body, and an elastic element is connected between the wedge and the rotating plate. A rotating motor is fixedly connected to the rotating plate, a rotating rod is fixedly connected to the output shaft of the rotating motor, and a mating part for sliding cooperation with the inclined surface of the wedge is fixedly connected to the rotating rod; The rotating motor drives the rotating rod to rotate, and the rotating rod drives the opposing parts to pass through the inclined surfaces of multiple wedges in sequence.

[0027] In this design, a rotating motor drives a rotating rod to rotate, which in turn causes the abutting component to sequentially pass over the inclined surfaces of multiple wedges. When the abutting component passes over the inclined surface of a corresponding wedge, it pushes the wedge, causing the wedge to push the sliding part to slide on the rotating plate, thus moving the sealing plate. When the abutting component leaves the corresponding wedge, an elastic element causes the sliding part to slide in the opposite direction, and the sealing plate moves in the opposite direction. Therefore, this design achieves automatic sequential movement control of multiple sealing plates without manual intervention, enabling the sequential opening and sealing of different pipe holes.

[0028] Preferably, as an improvement, the rotating rod includes a fixed rod and a sliding rod, the sliding rod is slidably connected to the fixed rod, the fixed rod is fixedly connected to the output shaft of the rotating motor, a guide groove is provided on the rotating plate, and a driven rod is fixedly connected to the sliding rod, the driven rod is slidably located in the guide groove.

[0029] The distance from the ends of different pipe holes on the housing to the axis of the rotating motor will vary. This results in different positions for the sealing plates and wedges corresponding to different pipe holes, and different distances from the wedges to the axis of the rotating motor. In this design, the guide groove is set according to the distance from the wedges to the axis of the rotating motor. With this design, the rotating motor's rotating rod rotates, and the driven rod on the rotating rod slides in the guide groove. The driven rod, following the direction of the guide groove, drives the sliding rod to slide on the fixed rod, thus achieving adjustment of the rotating rod's length. When the sliding rod moves on the fixed rod, it drives the abutting component to move along the axial direction of the sliding rod, thereby achieving automatic adjustment of the abutting component's position in the axial direction of the rotating rod, ensuring that the abutting component can push wedges at different distances from the axis of the rotating motor.

[0030] Preferably, as an improvement, the abutting component includes a roller and a frame, with the roller rotatably connected to the frame. Thus, the roller of the abutting component slides on the inclined surface of the wedge, resulting in less friction between the abutting component and the wedge. Attached Figure Description

[0038] Figure 8 This is a schematic diagram showing the connection of the rotating motor, rotating rod, abutting part, and driven rod in Example 4. Detailed Implementation

[0039] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame 1, detection platform 2, top plate 3, suction box 4, moving plate 5, box body 6, fixed cylinder 7, rotating plate 8, rotating disk 9, bracket 10, drive motor 11, suction cover 12, hole 13, drive component 14, drive component frame 15, second pipe hole 17, first pipe hole 16, rotating motor 18, rotating rod 19, frame body 20, roller 21, wedge block 22, elastic element 23, sliding part 24, sealing plate 25, vent hole 26, first groove 27, second groove 28, connecting part 29, driven rod 30, fixed rod 31, sliding rod 32, protective cover 33, guide groove 34. Example 1

[0040] The basics are as follows: Figures 1-4As shown: A foreign object detection device for box-type parts includes a frame 1 and a camera. The frame 1 is equipped with a detection platform 2 and a top plate 3. A camera with a downward-facing lens is mounted on the lower side of the top plate 3, which can capture images of the detection platform 2.

[0041] The foreign object detection device for box-type parts in this embodiment also includes, A rotating component, on which a fixing component is provided for fixing the box 6 to the rotating component; A drive component used to drive rotating parts to flip; And a suction component, which includes a movable suction box 4, which has negative pressure.

[0042] Combination Figure 2 As shown, the rotating component in this embodiment specifically includes a rotating plate 8 and a support block fixed on the rotating plate 8. The fixing component in this embodiment is specifically a fixing cylinder 7. There are multiple fixing cylinders 7; four are shown in the figure. These cylinders are located around the support block and are mounted on the rotating plate 8. When the box body 6 is placed on the support block, the pressure block on the fixing cylinder 7 presses down on the outer ear plate of the box body 6. The outer ear plate of the box body 6 is pressed against the support block, thus firmly fixing the box body 6 to the support block.

[0043] The driving component in this embodiment includes a bracket 10, a drive motor 11, and a rotating disk 9. The rotating disk 9 is rotatably connected to the bracket 10 via bearings. The drive motor 11 is mounted on the bracket 10. A driven gear (located inside the bracket 10, not shown in the figure) is fixedly provided on the circumferential side wall of the rotating disk 9. A driving gear (located inside the bracket 10, not shown in the figure) is coaxially fixed on the output shaft of the drive motor 11. The driven gear and the driving gear mesh. A rotating plate 8 is fixed to the end of the rotating disk 9 by bolts. Thus, the drive motor 11 drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the rotating disk 9 to rotate, and the rotating disk 9 drives the rotating plate 8 to rotate. Figure 1 The detection platform 2 is equipped with a protective cover 33, which covers the drive motor 11 and the bracket 10.

[0044] Combination Figure 2 and Figure 3As shown, in this embodiment, the suction component is mounted on the detection platform 2. The detection platform 2 has a vertical through hole. Specifically, the suction component also includes a movable plate 5 and a driving component 14 for moving the movable plate 5. The movable plate 5 is located in the through hole, and the suction box 4 is fixed to the upper surface of the movable plate 5 by screws or bolts. A driving component frame 15 is fixed to the lower surface of the detection platform 2, and the driving component 14 is mounted on the driving component frame 15. The driving component 14 is specifically an electric cylinder, and its telescopic rod is fixed to the movable plate 5. Thus, through the extension and retraction of the telescopic rod of the driving component 14, the driving component 14 drives the movable plate 5 to move vertically in the through hole, and the movable plate 5 drives the suction box 4 to move vertically.

[0045] To generate negative pressure inside the suction box 4, the following method can be used: a negative pressure pump (not shown in the figure) is installed on the lower side of the movable plate 5. The negative pressure pump is connected to the suction box 4, thus creating negative pressure inside the suction box 4 by suctioning through the negative pressure pump. Of course, since the negative pressure pump has a certain size, it can also be installed outside the movable plate 5 instead of on the movable plate 5. Figure 3 As shown, a suction hood 12 is installed on the lower surface of the movable plate 5. The suction hood 12 is connected to the suction box 4. The suction hood 12 has a hole 13. A negative pressure hose is connected to the negative pressure machine. The negative pressure hose is connected to the hole 13 of the suction hood 12. In this way, the negative pressure machine generates negative pressure. The negative pressure machine sucks the suction inside the suction hood 12 through the negative pressure hose, thereby generating negative pressure inside the suction box 4.

[0046] In this embodiment, the edge of the suction box 4 and the edge of the box body 6 are adapted to each other, so that the suction box 4 and the box body 6 can fit together well.

[0047] The specific implementation process is as follows: Place the box 6 on the rotating component, and fix the box 6 on the rotating component using the fixing component, combined with... Figure 1 As shown, the inside of box 6 is facing upwards, and the camera is in a state of relative position to the inside of box 6. The camera takes pictures of the inside of box 6, thereby realizing the detection of foreign objects inside box 6.

[0048] When it is necessary to clean foreign objects from inside the box 6, the drive motor 11 drives the drive gear to rotate, which in turn drives the driven gear to rotate. The driven gear then drives the rotating disk 9 to rotate, which in turn drives the rotating plate 8 to flip, thus causing the inside of the box 6 to face downwards. (Refer to the attached diagram for further details.) Figure 5Since the inside of box 6 faces downwards, it is in a relative position to the suction box 4. Then, the driving component 14 drives the moving plate 5 to move upwards, which in turn drives the suction box 4 to move upwards. The edge of the suction box 4 is aligned with the edge of box 6, and the suction box 4 closes onto box 6. At the same time, the negative pressure machine is activated, creating negative pressure inside the suction box 4. The suction box 4 then sucks out the foreign objects from box 6, removing them and storing them in the suction box 4 or the suction cover 12. Example 2

[0049] Combination Figure 4 As shown, multiple pipe holes are connected to the side of the box 6. The number and position of the pipe holes will vary depending on the type of box 6. In this embodiment, the following is used: Figure 4 Let's take box 6 as an example for explanation. Figure 4 There are two central tube holes, namely the first tube hole 16 and the second tube hole 17.

[0050] Using the device of Example 1 Figure 4 When foreign objects are suctioned out, external air enters the box 6 through the first orifice 16 and the second orifice 17. Since there are two orifices, the gas entering the box 6 through the first orifice 16 and the second orifice 17 will be dispersed, resulting in a small amount of gas or a low air intake speed in each orifice. This is not conducive to cleaning foreign objects in the first orifice 16 and the second orifice 17. If the foreign objects are firmly adhered to the inner wall of the orifice, the foreign objects on the inner wall of the orifice cannot be effectively cleaned when the amount of gas entering the orifice is small or the air intake speed is low.

[0051] Therefore, in order to solve the above problems, this embodiment is further improved based on embodiment 1.

[0052] Combination Figure 5 As shown, in this embodiment, two sealing plates 25 are movably connected to the rotating plate 8. The sealing plates 25 seal the pipe holes on the box body 6, and the sealing plates 25 are provided with vent holes 26. The specific movement of the sealing plates 25 on the rotating plate 8 is as follows: the sealing plates 25 are located on the side of the rotating plate 8 where the box body 6 is located. A sliding part 24 is integrally connected to the end of the sealing plates 25. The sliding part 24 is specifically square rod-shaped. The sliding part 24 passes through the rotating plate 8 and slides with the rotating plate 8. A wedge block 22 is integrally fixed to the end of the sliding part 24 away from the sealing plates 25. The wedge block 22 is provided with an inclined surface. An elastic element 23 is provided between the wedge block 22 and the rotating plate 8. The elastic element 23 is specifically a compression spring and is sleeved on the sliding part 24.

[0053] A rotating motor 18 is bolted to the rotating plate 8. A rotating rod 19 is fixedly connected to the output shaft of the rotating motor 18, and the rotating rod 19 is perpendicular to the output shaft of the rotating motor 18. A mating component for sliding engagement with the inclined surface of the wedge block 22 is fixedly connected to the rotating rod 19. In this embodiment, the mating component specifically includes a roller 21 and a frame 20. The frame 20 is fixed to the rotating rod 19, and the roller 21 is rotatably connected to the frame 20. The roller 21 can roll on the inclined surface of the wedge block 22.

[0054] The rotating motor 18 drives the rotating rod 19 to rotate, and the rotating rod 19 drives the abutting part to move together. The roller 21 at the bottom of the abutting part passes through the inclined surface of multiple wedges 22 in sequence.

[0055] In this embodiment, the box body 6 is mounted on the rotating plate 8. Initially, the two sealing plates 25 seal the first pipe hole 16 and the second pipe hole 17 respectively, and both the first pipe hole 16 and the second pipe hole 17 are in a sealed state.

[0056] When suction is performed in the suction box 4 and the box body 6, the rotating motor 18 is started at the same time, and the rotating motor 18 drives the rotating rod 19 to rotate. Figure 5 The rotating motor 18 rotates clockwise, and the rotating rod 19 drives the roller 21 of the abutting part to pass through the inclined surfaces of the two wedges 22 in sequence. When the abutting part passes through the inclined surface of the wedge 22 on the sealing plate 25 corresponding to the first pipe hole 16, the roller 21 pushes the corresponding wedge 22, and the wedge 22 pushes the sliding part 24 to slide on the rotating plate 8. The elastic element 23 is squeezed, and the sealing plate 25 moves downward. The vent 26 on the sealing plate 25 is aligned with the first pipe hole 16, and the first pipe hole 16 changes from a blocked state to an open state. At this time, external gas enters the box 6 only through the first pipe hole 16. When the roller 21 leaves the wedge 22, the wedge 22 moves upward and resets under the elastic force of the elastic element 23. The wedge 22 drives the sealing plate 25 to move upward through the sliding part 24, and the sealing plate 25 continues to seal the first pipe hole 16.

[0057] Similarly, as the rotating motor 18 rotates, the abutting component will pass over the inclined surface of the wedge 22 on the sealing plate 25 corresponding to the second pipe hole 17. At this time, the roller 21 pushes the other wedge 22, and the wedge 22 pushes the sliding part 24 to slide on the rotating plate 8. The elastic element 23 is squeezed, and the sealing plate 25 moves downward. The vent 26 on the sealing plate 25 is aligned with the second pipe hole 17, and the second pipe hole 17 changes from a blocked state to an open state. At this time, external gas enters the box 6 only through the second pipe hole 17. When the roller 21 leaves the wedge 22, the wedge 22 moves upward and resets under the elastic force of the elastic element 23. The wedge 22 drives the sealing plate 25 to move upward through the sliding part 24, and the sealing plate 25 continues to seal the second pipe hole 17.

[0058] Therefore, through this embodiment, the automatic sequential movement control of the two sealing plates 25 is achieved without manual control of the movement of the sealing plates 25. This allows the first pipe hole 16 and the second pipe hole 17 to be opened and closed sequentially. The first pipe hole 16 and the second pipe hole 17 will not open simultaneously, so that the gas entering the box 6 will only enter through one pipe hole. When the gas enters from one pipe hole, the other pipe holes are in a blocked state and will not disperse the amount of gas entering the box 6. The gas flow rate or the intake volume in the pipe hole is relatively large, which can fully blow away foreign objects in the pipe hole and fully clean the foreign objects in the pipe hole. Example 3

[0059] In Example 2, two pipe holes are used for illustration. Of course, it is easy to understand that the number of pipe holes may be more than two. When the number of pipe holes is more, more wedges 22, sealing plates 25, elastic elements 23, and other structures need to be provided.

[0060] Combination Figure 6 As shown, when there are eight pipe holes and the distance from the pipe holes to the rotating motor 18 in the lateral direction is the same, the eight wedges 22 will be arranged around the rotating motor 18. At this time, the rotating motor 18 rotates, which drives the rotating rod 19 to rotate. The rotating rod 19 drives the abutting parts to pass through different wedges 22 in sequence, thereby pushing the different sealing plates 25 respectively. Example 4

[0061] Of course, in practice, due to differences in the position and length of the pipe holes, the distance from the end of different pipe holes on the box 6 to the axis of the rotating motor 18 will be different. This results in different positions for the sealing plate 25 and wedge 22 corresponding to different pipe holes, and different distances from the wedge 22 to the axis of the rotating motor 18. To address this scenario, this embodiment is further improved based on embodiment 2 or embodiment 3.

[0062] Combination Figure 7 and Figure 8 As shown, the rotating rod 19 in this embodiment includes a horizontally fixed rod 31 and a horizontally sliding rod 32. The sliding rod 32 is slidably connected to the fixed rod 31. Specifically, the fixed rod 31 has a rod cavity, into which the sliding rod 32 is inserted and can slide. The fixed rod 31 is fixedly connected to the output shaft of the rotating motor 18. The rotating plate 8 has a guide groove 34 on one surface where the rotating motor 18 is located. A driven rod 30 is fixedly connected to the sliding rod 32. The driven rod 30 is vertically arranged, and its bottom end slides in the guide groove 34.

[0063] In this embodiment, the rotating motor 18 rotates the rotating rod 19, and the driven rod 30 on the rotating rod 19 slides in the guide groove 34. The driven rod 30 drives the sliding rod 32 to slide on the fixed rod 31 according to the direction of the guide groove 34, thereby realizing the length adjustment of the rotating rod 19. During the sliding of the sliding rod 32 on the fixed rod 31, the sliding rod 32 drives the abutting member to move along the axial direction of the sliding rod 32, thereby realizing the automatic adjustment of the position of the abutting member in the axial direction of the rotating rod 19, so that the abutting member can move to the corresponding wedge 22 in the axial direction of the rotating rod 19, ensuring that the abutting member can push the wedge 22 at different distances from the axis of the rotating motor 18.

[0064] The following description uses a specific scenario as an example. Figure 7 As shown, four pairs of wedges 22 are provided above the rotating plate 8. Two pairs of opposing wedges 22 are located farther from the rotating motor 18 and on both sides of the rotating motor 18, while the other two pairs of opposing wedges 22 are located closer to the rotating motor 18 and on both sides of the rotating motor 18. The guide groove 34 is divided into two first grooves 27, two second grooves 28, and a connecting part 29. The two first grooves 27 are opposite each other, and the two second grooves 28 are opposite each other. The first grooves 27 are located between the rotating motor 18 and the wedges 22 that are farther from the rotating motor 18, and the second grooves 28 are located between the rotating motor 18 and the wedges 22 that are closer to the rotating motor 18. The distance between the first grooves 27 and the rotating motor 18 is greater than the distance between the second grooves 28 and the rotating motor 18. The connecting part 29 is located between the first grooves 27 and the second grooves 28, thereby connecting the first grooves 27 and the second grooves 28. In this embodiment, there are four connecting parts 29. The guide groove 34 in this embodiment is arranged in a closed loop.

[0065] Therefore, the rotating motor 18 drives the rotating rod 19 to rotate, and the driven rod 30 slides in the guide groove 34. When the driven rod 30 slides in the first groove 27, the length of the rotating rod 19 is relatively long, and the abutting member on the sliding rod 32 can act with the wedge 22 corresponding to the first groove 27. When the driven rod 30 moves to the second groove 28 through the connecting part 29, since the second groove 28 is closer to the rotating motor 18, the driven rod 30 drives the sliding rod 32 to slide on the fixed rod 31, the length of the rotating rod 19 becomes shorter, and the sliding rod 30 drives the abutting member to move closer to the rotating motor 18. At this time, the abutting member on the sliding rod 32 can act with the wedge 22 corresponding to the second groove 28.

[0066] Of course, in different implementations, the shape of the guide groove 34 can be designed into different closed shapes according to the specific shape of the box 6.
